(2) In this state, the carry-in device 15 is moved in the width direction of the overflow gutter 50 (direction of arrow A in the figure) to move the cleaning device 30 to the end part of the overflow gutter 50 to be cleaned. Move to the top. When moving in the direction of arrow A, the carrying-in device 15 (that is, the cleaning device 30) is positioned by a limit sensor (not shown) attached to the rail 13.

(3) After this positioning is performed, as shown in FIG. 3, the ladder unit 19 of the carry-in device 15 is lowered right below (in the direction of arrow B in the drawing) to clean the cleaning device 30.
Are carried into the overflow gutter 50. At this time, the cleaning device 30
The roll type resin brush 41 is located outside the overflow gutter 50. When moving in the direction of arrow B, the loading device 15
The ladder unit 19 (that is, the cleaning device 30) is positioned by a limit sensor (not shown) attached to the main body 22 of the.

(4) Next, the cleaning device 30 includes the motor 43
After the rotation of the roll type resin brushes 39 and 41 is started by the motor 32, the wheels 37 of the carriage 38 are rotated by the motor 32, and as shown in FIG. 4, the longitudinal direction of the overflow gutter 50 (direction of arrow C in the figure). Drive to.

At this time, the rotating roll type resin brush 3
The tips of the brushes 9, 41 are the inner and outer surfaces 50 of the overflow gutter 50.
The reaction force received from a and 50c is also used as the driving force of the cleaning device 30. In addition, the cleaning device 30 is guided by the guide roller 35, so that the inner surface 50 of the overflow gutter 50 is guided.
Drive following a.

Then, the roll type resin brushes 39 and 41 rotate together with the carriage 38 while moving in the direction of arrow C, and the flat type resin brushes 36 and 40 move together with the carriage 38 in the direction of arrow C, and the overflow gutter. Algae and sludge (hereinafter referred to as algae) which are the objects to be removed are removed from each part of 50. That is, the roll-type resin brush 39 removes algae or the like from the inner side surface 50a of the overflow gutter 50, and the roll-type resin brush 41 uses the outer side surface 50a.
c and the outer surface 55a-1 of the notch of the overflow plate, algae and the like are removed from the inner bottom surface 50b of the flat resin brush 36, and algae and the like from the corner 50d of the flat resin brush 40. To remove. The algae removed inside the overflow gutter 50 and the algae removed outside the overflow gutter 50 and overflowed into the overflow gutter 50 together with the treated water are strain nets 26 provided in the ladder portion 19 of the carry-in device 15. (See FIG. 4). That is, in the overflow gutter 50, the treated water that has flowed over the overflow plate 55 and flows into the overflow gutter 50 (overflow) is constantly flowing toward the drainage port 3, and the alga removed is treated by this treatment. It is collected by the strainer net 26 by being washed with water.

The inner and outer side surfaces 50a, 50 of the overflow gutter 50
The protrusions such as the bolts 56 and 57 in c do not hinder cleaning because the bristles of the roll-type resin brushes 39 and 41 have a sufficient length in consideration of the size of the protrusion.

(5) Subsequently, the cleaning device 30 is operated by the overflow gutter 5
When the sensor 33 detects the same end when traveling to the end of 0, the vehicle runs in reverse and returns to the start point, and is mounted on the carry-in table 24 of the carry-in device 15 waiting at the start point again. During this reverse running, the motor 43 is rotated in reverse and the roll type resin brushes 39, 41 are rotated in reverse, so that the reaction force received from the overflow gutter 50 is used as the propulsive force of the cleaning device 30. When the cleaning device 30 travels (forwards) and runs in reverse, the motor 16 causes the cable reel 17 to rotate normally and reversely, so that the power cable 18 is fed and wound.

(6) After confirming that the cleaning device 30 is placed on the carry-in table 24 by the sensor (not shown) attached to the main body 22 of the carry-in device 15, the ladder portion 19 is raised (arrow in FIG. 3). (Direction opposite to B) and lift the cleaning device 30 upward.

(7) After that, the above-mentioned operations (1) to (6) are repeated for each of the other overflow gutters 50 to clean all the overflow gutters 50 in the settling basin 1 and finish the work. .

From the above, according to the cleaning device 30 and the carry-in device 15 according to the present embodiment, the following effects can be obtained.

(1) Even if the overflow gutter 50 to be cleaned has the FRP overflow plate 55 which is relatively easily damaged as described above, the overflow plate 55 is rolled by the roll type resin brushes 39 and 41.
Part (inner side surface 50a, outer side surface 50a of the notch portion 55a-
By cleaning 1), the overflow plate 55 (particularly the notch portion 55a) can be automatically cleaned faster and cleaner than before without damaging the overflow plate 55. Therefore, not only the manual work (3K work) is unnecessary and the problem of the work is solved, but algae and the like are reduced in the point that the cleaning can be performed more neatly than in the conventional method. The water quality of can be improved.

(2) Since the cleaning device 30 is provided with the guide roller 35, the cleaning device 30 is guided by the guide roller 35 so that it can travel stably following the inner side surface 50a of the overflow gutter 50. . Therefore, even if there are protrusions such as the bolts 57 on the inner peripheral surface 50a of the overflow gutter 50, there is no risk of contacting these protrusions, and the parts of the overflow gutter 50 are more reliably cleaned. be able to.

(3) Since the cleaning device 30 is provided with the floater 31, even if the cleaning device 30 falls into the sedimentation tank 1,
It can float without sinking, and can be towed on the water even if the carry-in device 15 cannot be used for some reason.

(4) The resistance of water is reduced by providing the motors 32 and 43 on the upper part of the carriage 38 so that the motors 32 and 43 are higher than the water surface in the overflow gutter 50. And the motors 32, 4
It is possible to prevent 3 from breaking down.

(5) Since the rotation directions of the roll-type resin brushes 39 and 41 are switched according to the traveling direction of the cleaning device 30, the cleaning device 30 is propelled by using the reaction force received from the overflow gutter 50. You can increase your strength.

(6) Since the roll type resin brushes 39 and 41 rotate to remove algae and the like, the removed algae and the like are unlikely to adhere to the brushes. Therefore, the removability of algae (especially algae) can be enhanced. The removability of the roll type resin brushes 39 and 41 will be described in detail later.

(7) Since the outer peripheral portion of the wheel 37 of the carriage 38 is made of rubber, it is possible to easily travel even if the inside of the overflow gutter 50 is slippery.

(8) The cleaning device 3 is carried out by the carry-in device 15.
0 can be easily carried into the overflow gutter 50 and recovered from the overflow gutter 50, and can be easily moved between the overflow gutters 50.

(9) When a control signal to the cleaning device 30 is to be transmitted by wire, the signal cable for that purpose must be shielded in order to integrally integrate the signal cable and the power cable 18, and the cable is thick. turn into. For this reason, the weight of the cable itself becomes heavy, the resistance of water to the cable becomes large, and the thrust force required to pull the cable becomes large. Therefore, the capacity of the motor 32 must be increased accordingly. On the other hand, by transmitting the control signal wirelessly as described above and using only the power supply cable 18 as the cable for connecting the carry-in device 15 and the cleaning device 30, the cable can be made thin. The weight of the cable itself is reduced, the water resistance to the cable is reduced, and the thrust required to pull the cable is reduced.
Therefore, the capacity of the motor 32 can be reduced accordingly. It is also effective to use the battery of the cleaning device 30 as a battery and remove the power cable 18 in order to reduce the thrust force required for the cleaning device 30.

By the way, the cleaning device 30 is provided with cylindrical roll type resin brushes 39, 41 as a cleaning tool for cleaning the inner side surface 50a and the outer side surfaces 50c, 55a-1 of the overflow gutter 50. However, the shape of the brush is not limited to this, and for example, the disk-shaped brush 81 shown in FIG. 6A, the truncated cone-shaped brush 82 shown in FIG. The flat brush 83 shown in c) may be used. In the case of the disk-shaped and frustoconical brushes 81 and 82, the brushes are rotated by the rotating mechanism, and in the case of the flat brush 83, the brushes are reciprocated by the reciprocating mechanism. In addition,
The bristles of the brush are preferably made of resin.

Further, in the above-mentioned cleaning device 30, since the inner bottom surface 50b and the corner portion 50d of the overflow gutter 50, which is a copper plate portion, are relatively free of algae and are easy to remove, they are fixed as cleaning tools for these. Although the flat resin brushes 36 and 40 are provided, of course, instead of these, various rotary brushes as described above may be provided. A scraper made of rubber or the like may be used instead of the brush. In the case of fixing, the cleaning tool on the inner bottom surface 50b and the cleaning tool on the corner 50d may be integrally configured.

In other words, the type of cleaning tool (brush or scraper), shape, mechanism (fixed or driven) can be appropriately selected according to the situation.

However, as described in (6) above, it is preferable to use rotary brushes such as the roll type resin brushes 39 and 41 in that they are excellent in removing algae. Hereinafter, the removability of this alga will be described in detail.

First, the characteristics of algae will be described with reference to FIG. FIG. 7 (a) is a perspective view showing the growth of algae, and FIG. 7 (b) is a sectional view taken along the line EE of FIG. 7 (a). As a result of detailed investigations and experiments, it was found that the algae that grow in the overflow gutter 50 can be classified into three types of algae M1, M2, and M3 shown in FIG. 7 from the viewpoint of their removal difficulty.

The first alga M1 has a corner 50d and an inner bottom surface 50.
It is an alga that grows on the copper plate part such as b, and is not rooted because it grows on the copper plate part with a smooth surface. Therefore, it is easily removed by rubbing it with the fixed flat resin brushes 36 and 40 as described above. be able to. The second alga M2 is an alga that grows on the inner surface 50a (that is, the surface of the overflow plate 55). Since the overflow plate 55 is made of FRP on the surface of the overflow plate 55 and is more easily damaged than the copper plate 52. Since there are fine scratches due to a brush or the like, the scratches are rooted between these fine scratches and cannot be easily removed by rubbing with a fixed brush such as the flat resin brushes 36 and 40. Third
The algae M3 are the outer surface 55a-1 of the overflow plate 55 and the overflow gutter 5
It is an alga that grows on the boundary with the upper end surface of 0 and is deeply rooted in the gap of this boundary, so it cannot be removed only by rubbing with a fixed brush.

Therefore, the second and third alga M2, M3 are
It should be removed with a moving brush rather than a fixed brush. 8, 9 and 10 show examples of the movable brush.
8A and 8B are a side view and a front view showing a cleaning state of the inner side surface by a movable flat resin brush, and FIG. 9 is a front view showing a cleaning state of the inner side surface by a movable roll type resin brush, 10 (a) is a side view showing a state of cleaning the inner side surface by a movable disk-shaped resin brush, and FIG. 10 (b) is FIG.
It is a NN sectional view taken on the line of (a).

However, as shown in FIG. 8, the flat resin brush 101 is reciprocally moved as indicated by an arrow in the drawing to move the second algae from the inner side surface 50a of the overflow gutter 50 (the surface of the overflow plate 55). When trying to remove M2, the removed second alga M2 is entangled with the bristles of the flat resin brush 101 and is gradually accumulated, so that the removal ability of the flat resin brush 101 decreases. The first alga M1 can be removed even by the flat resin brush 101 having the reduced removal ability in this way, but the second alga M2 is rooted on the inner surface 50a, The flat resin brush 101 whose removal ability has deteriorated cannot be removed.

On the other hand, as shown in FIG. 9, when removing the second alga M2 while rotating the roll type resin brush 39 as shown by the arrow in the figure, the flat type resin brush 10 is used.
As in No. 1, the removal ability is not deteriorated by the algae entwined with the hair tips.

In other words, paying attention to a part of the bristle tips of the roll type resin brush 39 in the circumferential direction, since the roll type resin brush 39 is rotating as shown in the figure, the inner tip surface 50 is the same.
The contact and separation with respect to a will be repeated. For this reason, the algae removed when the tip of the same hair contacts the inner side surface 50a is blown to the surroundings by the centrifugal force when the tip of the same hair separates from the inner side surface 50a. For this reason, the same hair tip is repeatedly brought into contact with the inner surface 50a repeatedly in a new state, and the removal ability is not deteriorated due to the entanglement of algae. Therefore, even in the bristles on the entire circumference of the roll-type resin brush 39, the removal ability does not decrease due to the entanglement of algae. For this reason,
Not only the first alga M1 but also the second alga M2 rooted on the inner surface 50a can be continuously removed. In addition,
The roll-type resin brush 41 also has the same operation and effect as the roll-type resin brush 39, particularly in cleaning the outer surface 55a-1 of the overflow plate 55.

Further, also by the disc type resin brush 103 as shown in FIG. 10, the same operation and effect as those of the roll type resin brush 39 can be obtained, and the second alga M2 can be removed. The bristles of the disk-shaped resin brush 103 are inclined outward at a predetermined angle θ with respect to the inner surface 50a. By tilting the hair in this way, when removing the second alga M2 while rotating it as indicated by the arrow in the figure, the removed alga is blown to the surroundings by the centrifugal force. Therefore, also in the disk-shaped resin brush 103, the algae is unlikely to be entangled with the bristle tips, and unlike the flat resin brush 101, the removal ability is not lowered by the entanglement of algae. Of course, when the angle θ is 0 degrees, the algae cannot be removed, but even when the angle θ is 90 degrees, the algae cannot be thrown into the surroundings and become entangled with the algae. You will not be able to do it.

Since the remaining third alga M3 is deeply rooted in the second alga M2 and above, it is difficult to remove it beyond the second alga M2 and above. The third alga M3 can be removed by a roll type resin brush dedicated to this alga. FIG.
1 (a) and 1 (b) are a side view and a front view showing the removal state of algae by such a roll type resin brush. As shown in the figure, the roll-type resin brush 106 is one in which a small amount of bristles corresponding to the width of the root 104 of the third alga M3 is provided around the rotary shaft, and the cleaning device 30 (see FIG. 1) is used. When it is carried into the overflow gutter 50, it is obliquely provided on the upper part of the carriage 38 (see FIG. 1) so that the tips of the hairs come into contact with the root 104 in a concentrated manner, and the brush drive motor 105 drives the brush to rotate. Therefore,
According to this roll-type resin brush 106, the rotational force of the motor 105 is transferred to the root 104 of the third alga M3 via the bristle tips.
The third alga M3 can be removed by acting intensively on the root 104 and tearing it off from the root 104.

Instead of such a dedicated roll-type resin brush 106, a roll-type resin brush is constructed by combining the roll-type resin brush 106 and the roll-type resin brush 41 shown in FIG. The third alga M3 may be removed by a mold resin brush.

FIGS. 12 (a) and 12 (b) are a plan view and a front view showing a state of removing algae by such a roll type resin brush. As shown in the figure, the roll-type resin brush 107
Is composed of a cylindrical upper portion 107a and a lower portion 107b having different diameters, and is provided on the truck 38 shown in FIG. 1 so as to have the same positional relationship with the overflow gutter 50 as the roll type resin brush 41 shown in FIG. On the other hand, unlike the upper portion 41a of the roll-type resin brush 41, the upper portion 107a has two types of bristles 107a.
-1 and 107a-2. These hairs 1
07a-1 and 107a-2 are alternately provided around the rotary shaft, and are all arranged at intervals of 45 degrees. One of the bristles 107a-1 extends straight to the outer surface 55a-1 of the overflow plate 55, while the other bristles 107a-1 of the other bristles 107a-1.
2 extends obliquely downward toward the boundary between the outer surface 55a-1 and the upper end surface of the overflow gutter 50. For this reason, when the cleaning device 30 (see FIG. 1) is carried into the overflow gutter 50, the tips of the bristles 107a-1 extending right beside the outer surface 55a-1.
The tip of the bristles 107a-2 that extends diagonally downward while contacting the
Intensively contacts the root 104 of the alga M3.

Therefore, when the roll-type resin brush 107 is rotated by a motor (not shown) as indicated by an arrow in the figure, the bristles 107a-1 extending right beside the overflow plate 55a.
From the outer surface 55a-1 of the alga (similar to the second alga M2)
While the hairs 107a-2 extending diagonally downward are removed,
Similar to the roll-type resin brush 106 described above, the root 104
The third alga M3 is removed by tearing it off.

As shown in FIG. 7, a relatively deeply rooted alga M close to the third alga M3 grows also on the portion of the bolt 57 fixing the overflow plate 55. The bristles of the roll-type resin brush 39 (see FIG. 1) locally bend largely in the bolt 57, and the stress in this portion becomes larger than that in the other portions, so that the bristles can be removed.

Next, in order to further enhance and enhance the cleaning function of the cleaning device 30 and the carry-in function of the carry-in device 15,
Various configurations useful for the cleaning device 30 and the carry-in device 15 will be described in detail.

First, various configurations useful for the cleaning device 30 will be described.

<Removed Material Recovery Means> The cleaning device 30 is preferably provided with removed material recovery means. If the removed material is algae, it will reproduce again unless it is recovered, and if the removed material is sludge, it will accumulate at the bottom of the sedimentation basin 1 if not recovered. The removed matter collecting means is, for example, a known suction device or the like.

<Upper End Surface Cleaning Unit> FIGS. 13 and 14 are a plan view and a side view showing the structure of the upper end surface cleaning unit for cleaning the upper end surface at the end of the overflow gutter. As shown in both figures, the end of the overflow gutter 50 is abutting, and it is necessary to remove algae and the like accumulated on the upper end surface 50e (copper plate portion) at this abutting.

Therefore, in the cleaning device 30 shown in both figures,
An upper end surface cleaning unit 108 for removing algae on the upper end surface 50e is provided. This top surface cleaning unit 1
08 is mounted on the carriage 38 so that the moving direction of the movable portion 111a coincides with the width direction of the overflow gutter 50 (longitudinal direction of the upper end surface 50e).
Of the linear motor 111 provided on the upper front end of the lever, a lever 109 coupled to the movable part 111a and having a tip end side extending forward of the carriage 38, and a tip end of the lever 109 with the tip of the hair directed downward to the upper end surface. The flat resin brush 110 having a long bristle provided so as to come into contact with 50e. The stroke range of the movable portion 111a of the linear motor 111 is the width of the overflow gutter 50 (the length of the upper end surface 50e).
It corresponds to. Further, while the cleaning device 30 is traveling in the overflow gutter 50, the movable part 111a is controlled so as to be positioned at one end side or the other end side of the stroke range, whereby the brush tip part of the flat resin brush 110 is controlled. Touches the upper end surface 50f or 50g of the overflow gutter side.

Therefore, the upper end surface cleaning unit 1 having the above structure
According to 08, the cleaning device 30 is carried into the overflow gutter 50,
When the carriage 38 travels in the direction of arrow C, the flat resin brush 1
10 moves in the same direction as the carriage 38 to remove algae and the like accumulated on one upper end surface 50f of the overflow gutter side portion. When the carriage 38 reaches the end of the overflow gutter 50, the sensor 3
By detecting that 3 has reached the abutting surface 50h of the overflow gutter 50 and reached the same end, the carriage 30 stops at the same end as shown in FIGS. 13 and 14. After that, the flat resin brush 110 is driven by the linear motor 111,
The upper end surface 50e at the end of the overflow gutter is reciprocally moved in the longitudinal direction to remove algae and the like accumulated on the upper end surface 50e. When the cleaning of the upper end surface 50 is completed, the carriage 38 runs in the reverse direction and returns to the start point. At this time, the flat resin brush 110 has the other upper end surface 50g of the overflow gutter side portion.
Is located at the upper end surface 50, which moves with the carriage 38.
The algae and the like deposited on the e are removed.

As described above, by providing the upper end surface cleaning unit 108, it is possible to easily clean the upper end surface 50e at the end of the overflow gutter which is relatively difficult to clean.

The bristles of the flat resin brush 110 are long and easily bent, but this is for fail-safe.
That is, even if the flat resin brush 110 stops in the middle of the stroke range due to some cause of failure during cleaning of the upper end surface 50e and the carriage 38 runs backward in this state, the bristles of the flat resin brush 110 are Since it is long and easy to bend, the baffle plate 5 at the abutment part of the overflow gutter due to this hair catching
There is no risk of damaging 5. Even if the bristles of the flat resin brush 110 are long and easily bent, the upper plate 50e has no algae on the upper end surface 50e because the overflow plate 55 at the end of the overflow gutter has no serrated notch. Since there are only deposits such as
It can be removed sufficiently. Of course, the flat resin brush having short and strong bristles may be provided instead of the flat resin brush 110 by solving the above-mentioned problem of breakage by other means.

<Pressing Means> Further, in the above description, the attachment positions of the roll-type resin brushes 39 and 41 and the length of the bristles are adjusted so that the tips of these brushes are located at the inner and outer surfaces 5 of the overflow trough 50.
Although the roller type resin brushes 39 and 41 are moved by pressing means, the brush tips may be brought into contact with the inner and outer surfaces 50a and 50b. 15 and 16 are plan views showing the outline of the pressing means for the roll-type resin brushes 39, 41.

As shown in FIG. 15, each lever 114 is rotatably supported in the horizontal direction by joints 112 provided on both sides of the carriage 38 (see FIG. 1), and each tip of these levers 114 is supported. Roll type resin brush 39
Are rotatably supported. Then, the roll-type resin brush 39 is rotated together with the lever 114 by a driving means (motor, cylinder, etc.) not shown, and the roll-type resin brush 39 is provided on the lever 114.
The brush drive motors 117 provided at the respective tip end portions of the above are rotationally driven.

Therefore, according to the pressing means having the above structure, the roll type resin brush 39 is moved by the driving means.
The tip end of the roll-type resin brush 39 can be easily brought into contact with the inner side surface 50a by rotating the inner side surface 50a side by a preset angle according to the position of the inner side surface 50a. Therefore, even if there is an overflow gutter in which the position of the inner side surface is slightly different, it is possible to easily cope with it by simply changing the set angle in accordance with the position of the inner side surface. Moreover, when there is a relatively large protrusion in the middle of the inner side surface 50a, the protrusion can be avoided by rotating the roll-type resin brush 39 to the side opposite to the inner side surface 50a. Further, as shown by the alternate long and short dash line in FIG. 15, the abutting surface 50h can be cleaned by rotating the roll type resin brush 39 by the driving means at the end of the overflow gutter 50. In this case, the roll type resin brush 39 may be moved in the longitudinal direction of the lever 114 by another driving means (motor, cylinder, etc.) in order to adjust the distance from the abutting surface 50h.

On the other hand, as shown in FIG. 16, on the upper part of the carriage 38 (see FIG. 1), the rods 115 on both sides are linearly movable in the width direction of the overflow gutter 50 (a cylinder, a linear motor, etc.). ) 116 is provided, and the roll-shaped resin brush 41 is rotatably supported at each tip of the rod 115. Therefore, the roll type resin brush 41 is driven by the linear actuator 116 and moves linearly in the width direction together with the rod 115. Also,
The roll-type resin brush 41 is adapted to be rotationally driven by a brush drive motor 118 provided at each tip of the rod 115.

Therefore, according to the pressing means having the above structure, the roll-shaped resin brush 41 is moved by the linear actuator 116 toward the outer side surface 50c by a distance set in advance according to the position of the outer side surface a. The brush tip of the shaped resin brush 41 can be easily attached to the outer surface 50.
c can be contacted. Therefore, even if there is an overflow gutter in which the position of the outer surface is slightly different, it is possible to easily cope with it by simply changing the set distance in accordance with the position of the outer surface. Moreover, when there is a relatively large protrusion in the middle of the outer side surface 50c, the roll-shaped resin brush 41 is moved to the side opposite to the outer side surface 50c.
It is also possible to avoid the protrusion.

<Door type fixed brush> When the flat resin brushes 40 (see FIG. 1) are simply fixed as described above, the cleaning device 30 is placed in the carry-in table 24 (see FIG. 2) of the carry-in device 15. The resistance of the bristles of the flat resin brushes 40 is relatively large when the brace is stored in, and the bristles are bent along the side plate 24b of the carry-in table 24, so that the bristles are easily damaged. Therefore, it is preferable to use a door-type fixed brush as shown in FIG.

That is, the flat resin brush 40 shown in FIG.
Are rotatably supported in the horizontal direction by joints 120 provided at the lower portions on both sides of the carriage 38 (see FIG. 1). A spring 121 is provided between the flat resin brush 40 and the lower portions on both sides. It is installed.

Therefore, according to the door type fixed brush (door type fixed flat resin brush 40) having the above-mentioned structure, when the cleaning device 30 is reversed and stored in the carry-in table 24, the flat resin brush 40 is Is pushed by the side plate 24b of the carry-in table 24 and rotated to the front side of the cleaning device 30 as shown by the alternate long and short dash line in FIG.
In this state, it is stored in the carry-in table 24. Therefore, the resistance of the hair during storage is small, and the hair is not damaged. When the cleaning device 30 moves forward and comes out of the carry-in table 24, the flat resin brush 40 is rotated in a direction opposite to the above by the force of the spring 121, and during cleaning as shown by the solid line in FIG. Return to the state of.

<Vertical Moving Mechanism of Flat Resin Brush> Further, although the flat resin brush 36 is simply fixed in the above description, when the inner bottom surface 50b of the overflow trough 50 is uneven, The flat resin brush 36 may be configured to be vertically movable along this uneven surface.

That is, as shown in FIG. 18, the lever 122 extending forward of the carriage 38 is rotatably supported by the joint 129 at the lower front end of the carriage 38, and between the lever 122 and the lower front end. Is provided with a spring 128, and a flat resin brush 36 is provided at the tip of the lever 122.

Therefore, according to the flat resin brush 36 having the rotating mechanism having the above structure, when the inner bottom surface 50b has the unevenness as shown in the drawing, the flat resin brush 36 has the lever 122.
The rotation of moves up and down along the uneven surface as indicated by an arrow in the figure. As a result, the bristles of the flat resin brush 36 do not bend so much, and the tips of the bristles make proper contact with the uneven surface, so that the ability to remove algae and the like is further enhanced.

<Flat Resin Brush Structure> Further, since the flat resin brush 36 is an integral one extending in the width direction of the overflow gutter 50 (see FIG. 1), as shown in FIG. The flat resin brush 36 blocks the flow of the treated water toward the drainage port 3 (see FIG. 2) as indicated by the arrow in the figure, and thus the removed algae and the like flowing along with the treated water are also blocked. Are accumulated in front of the flat resin brush 36. For this reason, as shown in FIG. 20, two flat resin brushes may be provided instead of the integral flat resin brush 36.

That is, as shown in FIG. 20, two flat resin brushes 123A and 123A on the left and right are provided at the lower front end of the carriage 38.
B is provided. These flat resin brushes 123
A and 123B are inclined at predetermined angles θ ₁ and θ ₂ in the water flow direction in the overflow gutter 50 (direction toward the drainage port 3 shown in FIG. 2), overlap with each other in the width direction of the overflow gutter 50, and The overlapping portion has a predetermined space d.

Therefore, the flat resin brush 123 having the above structure
According to A and 123B, as shown by the arrow in the figure, the removed algae and the like are treated together with the treated water by the flat resin brush 123.
Flat resin brush 123 along the slopes of A and 123B
It flows through between A and 123B. Therefore, there is no risk that the removed algae will be dammed up and accumulated, and the overflow gutter 50
It is possible to further improve the cleaning ability of the inner bottom surface 50b.

<Multi-Wheel Drive, Crawler> The wheels 37 of the carriage 38 are preferably multi-wheel drive (for example, four-wheel drive). This is because the inside of the overflow gutter 50 is slippery,
This is because the multi-wheel drive that can disperse the propulsion force can travel more reliably. Further, it is effective to use crawlers instead of the wheels 37. When it is a crawler, it can travel reliably and the wheels 3
Since the contact area of the overflow gutter 50 with respect to the inner bottom surface 50b is larger than that of No. 7 and the surface pressure is low, there is no fear of damaging the inner bottom surface 50b (that is, the copper plate 52) than the wheel 37.

<Guide Roller Mechanism> Further, in the above, the guide roller 35 is simply urged by the spring rod 45. However, in this case, a relatively small step (small unevenness on the inner side surface) is formed in the inner side surface 50a of the overflow gutter 50. Etc.), but also when there is a relatively large step, there is a problem.

That is, the cleaning device 30 is run backward in the direction of the arrow K in FIG. 21 and is waiting in the overflow gutter 50.
The inner side surface 24c of the carry-in table 24 and the overflow gutter 5
Since there is a relatively large step between the inner side surface 50a of the cleaning device 30 and the inner side surface 50a of 0 (that is, between the guide roller 35 and the inner side surface 24c of the loading table 24), a large force is required to center the cleaning device 30 into the loading table 24. is necessary. Therefore, it is necessary to use the spring rod 45 having a strong force (large spring constant). However, when the spring rod 45 having such a strong force is used, the cleaning device 30 is less likely to enter the carry-in table 24 due to the strong reaction force of the spring rod 45. In particular, when the cleaning device 30 travels in the slippery overflow gutter 50, the wheels 37 of the carriage 38 and the inner bottom surface 5 of the overflow gutter 50.
Since the friction with 0b is limited, the resistance of the guide roller 35 interferes with the traveling of the cleaning device 30. If the force of the spring rod 45 is weak, the loading table 24
Not only cannot be centered, but also the guide roller 35 excessively moves inward while being pressed by the inner surface 24c of the carry-in table 24. Therefore, the roll-type resin brush 39
For example, the structure on the side of the truck 30 may come into contact with the inner side surface 24c and be damaged.

The problem is that the cleaning device 30 is installed in the loading table 2
Loading stand 24 when it is stored in 4 and carried into the overflow gutter 50
Positioning error and the cleaning device 30 running backwards
It is more conspicuous when there is a relative position error between the two when they are stored in 4.

As a means for coping with such a problem, it is conceivable that the roll type resin brush 39 has a long bristle to increase the clearance, but this makes the roll type resin brush 39 considerably large. Will end up.

Therefore, as an effective means for solving such a problem, the cleaning device 3 shown in FIGS. 21, 22 and 23.
At 0, a guide roller mechanism having a stopper is provided. The guide roller mechanism will be described in detail below with reference to FIGS. 21, 22, and 23. 21 is a plan view showing the structure of the guide roller mechanism, FIG. 22 is a side view showing the structure of the guide roller mechanism, and FIG. 23 is a front view showing the structure of the guide roller mechanism. Are not shown.

As shown in these figures, supporting members 203 are provided at the lower front end and the lower rear end of the carriage 38, and levers 202 are provided at the left and right ends of these supporting members 203 via a shaft 201. And is rotatably supported.
The guide roller 35 is attached to the tip of each lever 202.
Are provided respectively. These guide rollers 35 are
It is directed to the inner side surfaces 50a on the left and right sides of the overflow gutter 50, respectively. Further, spring rods 45 are respectively provided between the front ends of the levers 202 on the left and right sides. Each of these spring rods 45 expands and contracts in the width direction of the overflow gutter 50 and has an appropriate elastic force (details will be described later).
Inner surface 50a of overflow gutter 50 by urging guide roller 35
Abutting against.

Further, stoppers 204 are fixed to the left and right ends of each support member 203, respectively. The positions of these stoppers 204 are in an appropriate state (centered) such that the cleaning device 30 has a center position in the width direction of the cleaning device 30 and a center position in the width direction of the carry-in table 24, as indicated by a dashed line in FIG. (In the state of being stored) in the loading table 24, the levers 202 on the left and right sides, which are pressed by both inner side surfaces 24c of the loading table 24 and rotated together with the guide rollers 35,
It is adjusted in advance by the stopper position adjusting jig 205 in consideration of the width of the carry-in table 24 so that the stoppers 204 on both the left and right sides are substantially in contact with each other. That is, the stopper 2
04 stores the cleaning device 30 in the carry-in table 24,
The guide roller 35 is fixed to a position where the rotation amount of the guide roller 35 is limited and the cleaning device 30 can be forcibly centered.

Therefore, according to the guide roller mechanism having the above structure, even if there is a small step on the inner side surface 50a of the overflow gutter 50 (small unevenness of the inner side surface 50a, etc.), the elasticity of the spring rod 45 at the step portion. By changing the traveling position of the wheels 37 of the carriage 38 by the force, the cleaning device 30
Can be easily centered. Moreover, when the cleaning device 30 is loaded into the loading table 24, the lever 20 is actuated by the action of the stopper 204 provided in the guide roller mechanism.
2 (that is, the guide roller 35) is restricted so as not to rotate too much inward, so that the cleaning device 30 can be loaded into the loading table 2.
4 can be forcibly centered and properly stored.

That is, the cleaning device 30 is centered by the action of the spring rod 45 at the small step portion, while the cleaning device 30 is forcibly centered by the action of the stopper 204 at the large step portion. The spring rod 45 can be made to have a relatively weak force so that the travel of the guide roller 35 can be reduced, so that the resistance of the guide roller 35 can be reduced.

Although the above description has been given of the case where the guide roller mechanism is provided in the overflow gutter cleaning device, the present invention is not limited to such an overflow gutter cleaning device, and the left and right opposite sides parallel to each other are parallel to each other. The guide roller mechanism can be applied as long as it travels between the wall surfaces along the wall surface. In this case, if there is a large step (a large unevenness on the wall surface) on the left and right wall surfaces, the stopper position of the guide roller mechanism may be adjusted according to the step.

<Slide mechanism> In the above, the overflow gutter 5
Although the vertical position of the roll-type resin brush 41 for cleaning the outer side surface 50c of 0 is constant, even if the height of the gutter is slightly deviated along the longitudinal direction of the overflow gutter 50 (even if it is wavy) ), Good cleaning can be performed according to the height of the gutter, and the overflow gutter 5
Even if there is an obstacle in the middle of 0, the roll type resin brush 41 is slid up and down so that the obstacle can be avoided and the cleaning can be continued and the overflow gutter near the wall of the sedimentation basin can be cleaned. Make it possible. Various examples of the slide mechanism will be described below.

First, the first slide mechanism will be described with reference to FIGS.
And it demonstrates based on FIG. 24, 25, and 26 are a side view, a front view, and a plan view, respectively, showing the cleaning device having the first slide mechanism. Note that the inner roll-type resin brush 39 and the brush drive motor 343 are not shown in FIG. 25.

As shown in these figures, linear guides 303 are provided on both sides of the carriage 38, respectively.
The slider 304 of the linear guide 303 can slide vertically along the linear guide 303. The slide member 300 is fixed to a slider 304, and the brush drive motor 3 is attached to the slide member 300.
45 and the upper end surface guide roller 301 are fixedly installed, and the roll type resin brush 41 is rotatably installed. Therefore, the slide member 300 fixed to the slider 304, the brush drive motor 345, the upper end surface guide roller 301, and the roll type resin brush 41 are integrated,
It can slide in the vertical direction with respect to the carriage 38.

Moreover, as described above, the rotational force of the brush drive motor 345 is transmitted to the roll type resin brush 41 via the belt 302. In addition, the upper end surface guide rollers 301, when the cleaning device 30 is carried into the overflow gutter 50, the upper end surfaces 50f and 50g of the overflow gutter 50.
The slide member 300 is fixedly installed on the slide member 300. Further, the roll-type resin brush 41 includes a cylindrical upper portion 41a and a lower portion 41b having different diameters, and the cleaning device 30
Is carried into the overflow gutter 50, and the upper end surface guide roller 30
When 1 is placed on the upper end surfaces 50f and 50g of the overflow gutter 50, the brush tip of the large diameter upper portion 41a contacts the outer surface 55a-1 of the notch 55a of the overflow plate 55 and the small diameter lower portion 41b. The brush member is provided on the slide member 300 so as to contact the outer side surface 50c of the overflow gutter 50.

When the overflow gutter 50 is cleaned by the cleaning device 30 having the above-described first slide mechanism (FIGS. 24 to 26), the upper end surfaces 50f and 50g of the overflow gutter 50 are cleaned.
Even if the height of the upper end surface is slightly deviated (corrugated) along the gutter longitudinal direction, the upper end surface guide roller 301 is
Rolling (rotating) along the tops of f and 50g to move up and down along the height of the upper end surfaces 50f and 50g, and the roll type resin brush 41 also moves up and down along the height of the upper end surfaces 50f and 50g. To do. Therefore, the upper end surfaces 50f, 50 of the overflow gutter 50
Even if g is wavy, the brush tip portion of the upper portion 41a of the roll-type resin brush 41 is always the notch portion 55 of the overflow plate 55.
Since it contacts the outer surface 55a-1 of a and the tip of the brush of the lower portion 41b contacts the outer surface 50c of the overflow gutter 50, good cleaning can be performed. Even if there are obstacles such as protrusions on the upper end surfaces 50f and 50g, as long as the upper end surface guide rollers 301 can get over the obstacles,
Cleaning can be continued by overcoming (avoiding) obstacles.

When the cleaning device 30 is carried into the overflow gutter 50 by the carry-in device 15, as shown in FIG.
The slide member 300, the brush drive motor 345, the upper end surface guide roller 301, and the roll type resin brush 41 (hereinafter, these are also collectively referred to as “roll type resin brush etc.”) are integrated and positioned at the lower end of the linear guide 303 by their own weight. To do. Therefore, the overflow gutter 50 near the wall of the sedimentation tank 1 can be cleaned. The reason why the overflow gutter 50 can be cleaned near the wall will be further described with reference to FIG.

As shown in FIG. 25, the overflow gutter 50 installed at the end of the sedimentation tank 1 is installed close to the wall 4, and the passage 5 at the upper end of the wall 4 extends to the sedimentation tank 1. It consists of states. As shown in FIG. 25, if the roll-type resin brush 41 and the like are located at the lower end of the linear guide 303,
While holding the cleaning device 30 placed on the carry-in table 24 of the carry-in device 15 at a position slightly higher than the water surface 6, the horizontal direction from the adjacent overflow gutter 50 to the overflow gutter 50 near the wall (see FIG. 25). Even if the roll type resin brush 41 is moved to the direction of the arrow L) and set right above the overflow gutter 50 near the wall 4 (on the side of the wall), the roll type resin brush 41 is located below the passage 5, so the roll type resin brush 41 Does not collide with the passage 5. Therefore, this FIG.
Cleaning can be performed by lowering the cleaning device 30 from the above state and carrying it into the overflow gutter 50.

On the other hand, the roll type resin brush 41 and the like have the same height as that when the roll type resin brush 41 was carried into the overflow gutter 50 (height during cleaning work), that is, the roll type resin brush 4
Assuming that the first and the like are fixedly installed on the carriage 38 at the height of the middle portion of the linear guide 303, the carry-in table 2 of the carry-in device 15 is provided.
Even if the cleaning device 30 mounted on the No. 4 is moved in the horizontal direction (L direction) to set it just above the overflow gutter 50 near the wall 4, the roll-type resin brush 41 projects to the settling basin 1 side. It collides with the passage 5. That is, the roll type resin brush 41 and the like are mounted on the carriage 38 based on the height during cleaning work.
If the passage 5 of the settling basin 1 is overhanging, even if the cleaning device 30 is carried into the overflow gutter 50 near the wall, the cleaning device 30 collides with the passage 5 and the carry-in is not possible. It is possible, and the overflow gutter 50 near the wall cannot be cleaned. In the present technology, the roll type resin brush 41 and the like are slidably attached to the carriage 38 in consideration of such circumstances.

As described above, even if the passage 5 is constructed so as to overhang the settling basin 1, if the first slide mechanism is provided, the overflow gutter near the wall 4 does not collide with the passage 5. You can also clean 50.

Next, the second slide mechanism will be described with reference to FIGS.
8 will be described. 27 and 28 are a side view and a front view, respectively, showing the cleaning device having the second slide mechanism. 28, the inner roll-type resin brush 39 and the brush drive motor 343 are not shown.

As shown in these figures, a feed screw mechanism 310 is provided on each side of the carriage 38.
When the feed motor 311 of the feed screw mechanism 310 is rotated, the feed screw (included in the feed screw mechanism 310 and not visible in the figure) is rotated, and the feed nut 312 screwed to the feed screw moves vertically. . Slide member 31
3 is fixed to a feed nut 312, a brush drive motor 345 is fixedly installed on the slide member 313, and a roll type resin brush 41 is rotatably installed. Therefore, by driving the feed motor 311 to move the feed nut 312 up and down, the slide member 313, the brush drive motor 345, and the roll-type resin brush 41 fixed to the feed nut 312 are integrated into the carriage 38. And can slide up and down. The rotational force of the brush drive motor 345 is transmitted to the roll-type resin brush 41 via the belt 302, and the roll-type resin brush 41 rotates. The second slide mechanism does not include the upper end surface guide roller used in the first slide mechanism. The configuration of the other parts is the same as that of the first slide mechanism.

When the overflow gutter 50 is cleaned by the cleaning device 30 equipped with the above-mentioned second slide mechanism (FIGS. 27 and 28), the height of the roll type resin brush 41 is adjusted by driving the feed motor 311. Then, the outer surface 50c of the overflow gutter 50 can be satisfactorily cleaned by the outer roll type resin brush 41. In addition, the upper end surface 50 of the overflow gutter 50
A level detection sensor for detecting the heights of f and 50 g is provided, and the height of the roll-type resin brush 41 is finely adjusted according to the height of the upper end surfaces 50 f and 50 g detected by the level detection sensor during cleaning work. The feed motor 311 may be controlled to adjust. By doing so, even if the upper end surfaces 50f and 50g are wavy, the upper portion 41a of the roll-type resin brush 41 is always located on the outer surface 55 of the notch portion 55a.
Good cleaning can be performed by contacting a-1 and the lower part 41b contacting the outer peripheral surface 50c.

Further, the cleaning device 30 is provided with an obstacle sensor, and when the obstacle sensor detects an obstacle, the feed motor 311 is driven to shift the roll type resin brush 41 to the upper end position of the feed screw mechanism 310. By doing so, obstacles can be avoided. In addition, overflow gutter 5
Obstacles outside 0 include structures that support overflow gutter 50.

Further, in order to clean the overflow gutter 50 near the wall of the settling basin 1, the cleaning device 30 mounted on the carry-in table 24 of the carry-in device 15 is moved horizontally to directly above the overflow gutter 50 near the wall 4. When set to, the roll type resin brush 41 is moved to the lower end position of the feed screw mechanism 310 by driving the feed motor 311. By doing this,
The roll type resin brush 41 can be prevented from colliding with the passage 5, and the overflow gutter 50 near the wall can be cleaned.

Next, the third slide mechanism will be described with reference to FIG. In this slide mechanism, the carriage 38 is provided with one feed screw mechanism 320. This feed screw mechanism 3
When the feed motor 321 of 20 is rotated, a feed screw (which is included in the feed screw mechanism 320 and cannot be seen in the figure) is rotated, and the feed nut 322 screwed to the feed screw moves in the vertical direction. The pair of left and right slide members 323 are fixed to the feed nut 322, and the brush drive motor 345 is fixedly installed on each slide member 323 and the roll-type resin brush 41 is rotatably installed. Therefore, by driving the feed motor 321 to move the feed nut 322 up and down, the feed nut 3
The pair of left and right slide members 323, the brush drive motor 345, and the roll-type resin brush 41 fixed to the unit 22 can be slid together in the vertical direction with respect to the carriage 38 at the same time.

When the overflow gutter 50 is cleaned by the cleaning device 30 having the above-described third slide mechanism (FIG. 29), the height of the left and right roll type resin brushes 41 is adjusted by driving the feed motor 321. Then, the outer roll-type resin brush 41 enables good cleaning of the outer side surface 50c of the overflow gutter 50.

Further, the cleaning device 30 is provided with an obstacle sensor, and when the obstacle sensor detects an obstacle, the feed motor 321 drives the roll type resin brush 41 to move to the upper end position of the feed screw mechanism 320. By doing so, obstacles can be avoided. In addition, overflow gutter 5
Obstacles outside 0 include structures that support overflow gutter 50.

Further, in order to clean the overflow gutter 50 near the wall of the settling basin 1, the cleaning device 30 placed on the carry-in table 24 of the carry-in device 15 is horizontally moved to directly above the overflow gutter 50 near the wall 4. In the case of setting the roll type resin brush 41, the feed motor 321 is driven to shift the roll-type resin brush 41 to the lower end position of the feed screw mechanism 320. By doing this,
The roll type resin brush 41 can be prevented from colliding with the passage 5, and the overflow gutter 50 near the wall can be cleaned.

In the example described above, the settling tank 1 of the treatment plant
In order to clean the inner overflow gutter 50, the outer roll type resin brush 41 is configured to slide in the vertical direction.
When the cleaning target is different, the inner roll type resin brush 39 may be slid in the vertical direction, if necessary.

<Outer Brush Mechanism> In the above example, the roll type resin brush 41 that slides up and down by various slide mechanisms is used to clean the outer surface 50c of the overflow gutter 50. The brush mechanism of can also be adopted. Here, two examples of other brush mechanisms for cleaning the outer side surface 50c will be described with reference to FIGS. 30 and 31.

In the outer brush mechanism 400 shown in FIG. 30,
The slide portion 4 is attached to the substrate 401 attached to the carriage 38.
The first linear actuator 4 in which 02a moves up and down
02. In addition, the second linear actuator 4
03 is fixed to the upper end of the slide portion 402a,
The linear actuator 403 is provided at both ends with sliding portions 403a that expand and contract. As the linear actuators 402 and 403, cylinders or motor-driven linear actuators are used. An upper end of a stationary brush 404 is rotatably attached to the tip of each slide portion 403a.

Further, a torsion spring member is concentrically arranged in each slide portion 403a, one end of this torsion spring member is fixed to the slide portion 403a, and the other end of the torsion spring member is attached to the stationary brush 404. It is fixed. The torsion spring member prevents rotation of the stationary brush 404 when the moment in the R direction acting on the stationary brush 404 is less than or equal to a certain value (a value that occurs during normal cleaning), and is greater than or equal to a certain value (for example, stationary). When the brush 404 has a value that occurs when it collides with an obstacle), the stationary brush 404 is allowed to rotate.

This outer brush mechanism 400 allows the outer surface 5
0c when cleaning the linear actuator 402
Adjust the length of the slide part 402a of the
04 so as to face the cleaning portion of the outer side surface 50c, and the sliding portion 403a of the linear actuator 402.
The expansion / contraction length of the stationary brush 404 is adjusted so that the stationary brush 404 contacts the outer surface 50c with an appropriate contact pressure for cleaning. A reaction force generated by contacting the outer side surface 50c acts on the stationary brush 404, and a moment force for rotating the stationary brush 404 acts in the R direction. However, since the torsion spring member is provided, the stationary brush 404 rotates. Not, but good cleaning.

If the stationary brush 404 collides with an obstacle while the carriage 38 is traveling for cleaning, the stationary brush 40 resists the spring force of the torsion spring member.
4 rotates in the R direction to avoid obstacles. Then, after the stationary brush 404 has passed over the obstacle, the stationary brush 404 returns to the normal state shown in FIG. 30 by the spring force of the torsion spring member. Therefore, even if there are obstacles,
Cleaning can continue.

In the outer brush mechanism 500 shown in FIG. 31,
A brush arm 502 is rotatably attached to a base plate 501 attached to the carriage 38 with a fulcrum 503 as a rotation center. A brush drive motor 504 and a roll-type resin brush 505 rotated by the brush drive motor 504 are provided outside the brush arm 502.
Is provided. On the other hand, the inner end of the brush arm 502 is connected to the upper end of the cylinder 506, and the lower end of the cylinder 506 is connected to the substrate 501.

This outer brush mechanism 500 allows the outer surface 5
0c, when the cylinder 506 is extended as shown in FIG.
05 is set to the cleaning mode position as shown by the solid line in the figure.
On the other hand, when there is an obstacle, the cylinder 506 is contracted, and the roll type resin brush 505 is retracted upward as shown by the dotted line in the figure. By doing so, it is possible to avoid the obstacle and continue the cleaning.

<Other Cleaning Tools> It is also conceivable that the cleaning device 30 is provided with a cutting tool such as hair clippers or scissors, and the third alga M3 is cut off by this cutting tool.

Next, various useful constructions of the carry-in device 15 will be described.

<Fall Preventing Means> Since the carrying-in table 24 (see FIG. 2) simply mounts the cleaning device 30, if a large vibration or the like is caused during carrying-in of the cleaning device 30, The cleaning device 30 may fall off the carry-in table 24. For this reason, it is preferable to provide the carry-in table 24 with a fall prevention means as shown in FIG.

That is, the bottom plate 24 of the carry-in table 24 shown in FIG.
A hole 24e is formed in the center of a.
A rod-shaped stopper 124 having a tip end portion 124a bent upward is inserted through 4e. This stopper 1
24 is a bottom plate 24 via a hinge 125 with a spring.
It is rotatably supported by a, and the hinge 125 urges the tip portion 124a side to rotate upward. Then, as indicated by the alternate long and short dash line in the figure, while the cleaning device 30 is being carried in, the cleaning device 3 is moved by the tip portion 124a of the stopper 124 which is biased by the hinge 125 and rotated upward.
The axle 37a of the wheel 37 of 0 is locked. On the other hand, when the cleaning device 30 is carried into the overflow gutter 50, the base end portion of the stopper 124 is moved to the overflow gutter 50 as shown by the solid line in FIG.
The stopper 124 is pushed by the inner bottom surface 50b of the
The tip portion 124a side of the
a is disengaged from the axle 37a.

Therefore, according to the above fall prevention means, the stopper 124 can surely prevent the cleaning device 30 from falling while the cleaning device 30 is being carried in, and the stopper can be easily stopped when the cleaning device 30 is carried in. 124 can be released. Moreover, the structure is simple and inexpensive. The hole 125 also functions as a drain hole for removing the treated water from the inside of the carry-in table 24 when the carry-in table 24 is raised. Of course, if the hole 125 alone is insufficient for drainage, a drainage hole may be separately provided in the bottom plate 24a.

<Straining Net Structure> Further, at the lower end portion of the ladder portion 19 (rear portion of the carry-in table 24) shown in FIG. 32, two straining nets 26 can be attached to and removed from the front and rear. That is,
The strainer net 26 is doubled. With such a configuration, when the first strainer net 26 previously attached is clogged with the collected algae, the second strainer net 26 is attached to remove the first strainer net 26. It can be removed.
Of course, when the amount of collected algae is large, three or more strainer nets 26 may be detachable.

<Guide Rail Structure> As shown in FIG. 33, when the cleaning device 30 is carried into the overflow gutter 50, the ladder portion 19 of the carry-in device 15 has the rectangular portion 22b of the main body 22.
The guide rail 127 and the roller 126 of the ladder portion 19 are descended at this time.
If and are in contact with each other over the entire length of the guide rail 127 without any gap, when the center position in the width direction of the carry-in stand 24 and the center position in the width direction of the overflow gutter 50 are slightly displaced, the carry-in stand 24 is moved to the overflow gutter. Guide rail 1 as it will not fit inside 50
In the lower part of 27, some gap (play) is provided between the guide rail 127 and the roller 126. As a result, even if the widthwise center positions of the carry-in stand 24 and the overflow gutter 50 are slightly displaced, the carry-in stand 24 is provided with the inner surface 5 on one side of the overflow gutter 50.
The reaction force F of 0a pushes it toward the other inner side surface 50a and allows it to enter the overflow gutter 50.

The cleaning device 30 and the carry-in device 1 described above are used.
Although 5 is provided with an electric motor (motor 32 etc.) as a driving means, of course, other driving means such as an engine may be provided instead of these.

[0176]

As described above in detail with the embodiments of the invention, according to the gutter cleaning device of the present invention, even if the gutter to be cleaned has the FRP plate portion which is relatively easily damaged,
This FRP plate can be cleaned automatically faster and cleaner than before without damaging it. Therefore, not only manual work (3K work) becomes unnecessary and the problem of the work is solved, but also the removed substances such as algae are reduced compared to the conventional one in that it can be cleaned more cleanly than before. ,
The quality of treated water can be further improved in the treatment plant.

Further, by providing the gutter cleaning device with the guide roller, even if there is a protrusion on the inner side surface of the gutter, it can travel without coming into contact with the protrusion, and more reliably clean each part of the gutter. You can

Further, by providing the gutter cleaning device with a floater, the gutter cleaning device can be floated without sinking even if it falls into, for example, a settling basin of a treatment plant, and even if the carry-in device cannot be used for some reason. Can be towed over water.

Further, by providing the removed material collecting means in the gutter cleaning device, it is possible to prevent repropagation of algae and accumulation of sludge.

Further, the inner surface cleaning tool, the inner bottom surface cleaning tool, the corner cleaning tool or the outer surface cleaning tool is a roll type brush or a disk type brush having bristles inclined outward at a predetermined angle. Even if the removed product is easily entangled with algae,
With the roll type brush or the disc type brush, the object to be removed can be easily removed by being blown to the periphery by a centrifugal force.

Further, by using a roll type brush in which bristles extending toward the outer surface of the overflow plate and bristles extending toward the boundary between the outer surface and the upper end surface of the overflow gutter are provided alternately. Two types of algae, that is, the algae growing on the outer surface of the overflow plate and the alga growing on the boundary between the outer surface and the upper end surface of the overflow gutter can be removed by one roll-type brush.

Further, by providing the upper end surface cleaning tool and the cleaning tool driving means, the upper end surface at the end of the gutter which is relatively difficult to clean is also moved in the width direction of the gutter by the cleaning tool driving means. Therefore, it can be easily cleaned.

By providing the pressing means,
By this pressing means, the inner surface cleaning tool or the outer surface cleaning tool can be moved by a predetermined amount, and the inner surface cleaning tool or the outer surface cleaning tool can be easily pressed against the inner surface or the outer surface. Furthermore, when there is a relatively large protrusion in the middle of the inner surface or the outer surface, this protrusion can be avoided.

Further, the flat brush for cleaning the corners is provided with the horizontal rotating means, so that when the cleaning device is housed in the carry-in stand waiting in the gutter, the flat brush is pushed to the side of the carry-in stand. Since it is stored in a state of being rotated in the horizontal direction, the storage is easy and the bristles of the brush are not damaged.

Further, by providing the flat brush for cleaning the inner bottom surface with the vertical rotating means, when the inner bottom surface of the gutter has unevenness, the flat brush can move up and down along the uneven surface. You can Therefore, the tips of the hairs accurately contact the uneven surface, and the removal ability of the object to be removed can be further enhanced.

By configuring the inner bottom surface cleaning tool with two flat brushes, it is possible to flush the removed object without damming it.

Further, by having the guide roller and the urging means and further providing the stopper thereon to form the guide roller mechanism, the gutter cleaning device is centered by the action of the urging means in the small step portion on the inner side surface. On the other hand, at the large step portion, the gutter cleaning device can be forcibly centered by the action of the stopper.
Therefore, in order not to hinder the traveling of the cleaning device, it is possible to make the biasing means relatively weak and reduce the resistance of the guide roller. That is, by including the guide roller mechanism in the cleaning device, the gutter cleaning can be performed without obstructing the running even when there is not only a small step inside the gutter but also a relatively large step (carrying table, etc.). The device can be guided and centered.

Further, the side cleaning tool and the roll type brush are provided in the slide member of the slide mechanism, and the upper end surface guide roller provided in the slide member is caused to travel along the upper end surface of the gutter, so that the gutter can be waved. Even if it is hit, the side surface cleaning tool and the roll type brush accurately follow the height of the gutter and come into contact with the cleaning target portion, so that good cleaning can be performed. Moreover,
When the cleaning device is located above the gutter, the side cleaning tool and the roll-type brush are located at the lower end of the slide mechanism, so even if the cleaning device is moved horizontally, it does not collide with the passage of the sedimentation pond. Therefore, the overflow gutter near the wall can be cleaned.

Further, the side surface cleaning tool and the roll type brush are provided in the slide member of the slide mechanism, and the height of the slide member is adjusted by the vertical driving device, so that the side surface cleaning tool and the roll type brush are The gutter can be accurately brought into contact with the part to be cleaned, and good cleaning can be performed. When there is an obstacle, the side surface cleaning tool and the roll-type brush are shifted upward, so that the obstacle can be avoided and cleaning can be continued. Further, by adjusting the positions of the side surface cleaning tool and the roll type brush, the cleaning device can be carried into the overflow gutter near the wall for cleaning.

Further, even if there is an obstacle, the stationary brush can be attached through a spring or the brush can be retracted upward so that the cleaning can be continued.

According to the carrying-in device of the present invention, the gutter cleaning device can be easily carried into the gutter and recovered from the gutter by the elevating means. Further, since the gutter cleaning device can be lifted, it is easy to move the gutter space in this state.

By providing the fall prevention means,
It is possible to prevent the cleaning device from dropping from the loading table. Moreover, the structure of the fall prevention means is simple and inexpensive.
