Also, the vertical swing range of the arm 40 is regulated by the stopper pin 43 to, for example, about 90 degrees as shown in FIG. 11, and this regulation pulls the extermination section chassis 4 upward. At this time, the arm 40 is prevented from swinging too much downward and reaching the side of the ship body 7 (see FIG. 1). As shown in FIG. 9, the tip of this arm 40 is curved downward at an angle of about 90 degrees, which enlarges the dimension from the lower end of the brush 33 to the arm 40, and the arm 40 is a protrusion on the seabed. To prevent contact with.

As shown in FIG. 12, the connecting mechanism 5 and the exterminating section 6 having the above-described structure are configured such that the lengths of the arms 40 are changed so that, for example, four front row exterminating section groups 44 and four rear row exterminating section groups 45 are provided. And the brushes 33 in the extermination section groups 44 and 45.
The extermination area of is partially overlapped at both edges in the width direction. As a result, it is possible to completely exterminate seaweeds on the seabed in the range from the extermination unit 6 at the right end in FIG. 12 of the front row extermination unit group 44 to the extermination unit 6 at the left end in FIG. 12 of the rear row extermination unit group 45. ing.

In addition, as shown in FIG.

5 can be prevented from being damaged.

Next, the operation of the present embodiment will be described.

In exterminating miscellaneous seaweed in the kelp fishing ground, first, the work mother ship 2 is sent to the work area, and the extermination part 6 is lowered into the sea by using the cranes 24 and 25 for both ships of the traction mechanism. At this time, the extermination unit chassis 4 is usually submerged in the sea, but may be located above the sea when the depth of the seabed is shallow.

Next, the anchor 17 fed out from the propulsion winch 9 is dropped to the front of the work end point using the work boat 20, and the anchor 16 fed out from the propulsion winch 8 is operated using the work boat 20. Drop behind the starting point. Then, the wire ropes 14 and 15 are wound by the winches 8 and 9 for both ships,
Stretch 5

Then, the motor 35 is started to start the brush 33.
Is rotated, and in this state, the wire rope 14 is wound and the wire rope 15 is paid out. This makes the ship body 7
Advances, and the work of exterminating seaweed is started.

As described above, the work of removing the seaweeds is performed by moving the work mother ship 2 straight, but when the control unit 6 does not move straight and skews to the left or right, the left half side and the right half side are removed. The rotation number of each brush 33 with respect to the side is adjusted to correct the direction. Further, when the depth of the seabed changes extremely and the angle of the arm 40 becomes too large or too small, the ship cranes 24 and 25 are vertically swung to vertically move the extermination part chassis 4 itself. In addition, when the step on the seabed is too large and the extermination section 6 cannot pass through this step, the ship cranes 24 and 25 are moved up and down before and after the step to avoid this step.

After the wire rope 14 has been wound up by the propulsion winch 8 to the work end point, the wire rope 15 of the anchor 17 is loosened and the anchor 17 is moved to the rear of the next work start point on the work boat 20. .

Next, the extermination unit 6 is once lifted to the sea by operating the ship cranes 24 and 25, and the work winch 8 is operated to move the work mother ship 2 to the next work start point. At the same time as this work, the anchor 16 is moved to the front of the next work end point by the work boat 20. After that, the extermination unit 6 is lowered into the sea, and the extermination work of the marine algae is repeated by the above-mentioned procedure.

In this way, when the extermination of seaweeds on the entire work area is completed, the wire ropes 14 and 15 are wound by driving the winches 8 and 9 for propulsion, and the anchors 16,
Store 17. After that, the extermination unit 6 is stored on the deck of the ship body 7.

In the above-mentioned seaweed extermination work, the entire work area is confirmed using the work mother ship 2 before the start of work.
It is desirable to check in advance the locations where there are reefs that are obstacles to the extermination work and where the work is difficult. At that time, if the position is confirmed by a signal from the GPS, more accurate positioning becomes possible.

However, since it is possible to exterminate the seaweeds on the seafloor simply by advancing the work mother ship 2, it is possible to exterminate a wide range of the seafloor in a short time without requiring large-scale equipment or many workers. Can be done at.

Further, in the conventional extermination method, the work efficiency cannot be improved even if the shape of the sea bottom is flat, but in the case of this embodiment, the work efficiency can be improved by simply rotating the brush 33 faster. It can be greatly improved.

FIG. 13 shows a second embodiment of the present invention. The bracket 3 in the first embodiment is shown in FIG.
Instead of 9, a bracket 59 with a built-in extermination unit chassis 4 is used.

In other respects, the structure is the same as that of the first embodiment and the operation is the same.

Therefore, even if this bracket 59 is used, the same effect as that of the first embodiment can be expected.

FIG. 14 shows the third embodiment of the present invention. The mounting position of the arm 40 of the front row extermination section group 44 to the extermination section chassis 4 and the arm 40 of the rear row extermination section group 45 are shown.
The mounting position on the extermination part chassis 4 is changed up and down.

That is, the arm 40 of the front row extermination unit group 44.
As shown in FIG. 14, the base end portion of the arm 40 of the rear row extermination unit group 45 is connected to the upper end portion of the extermination unit chassis 4 through the bracket 39.
It is connected to the lower end of the extermination part chassis 4 via 9.

In other respects, the structure is the same as that of the first embodiment and the operation is the same.

However, even if the connection mechanism 5 cannot be arranged at the same height position of the extermination section chassis 4 due to the structure of the side surface of the brush casing 34, etc., it can be divided into a plurality of upper and lower stages so that a large number of The extermination unit 6 can be attached to the extermination unit chassis 4.

FIG. 15 shows a fourth embodiment of the present invention, in which a front row extermination section group 44 and a rear row extermination section group 45 are separately attached to the front and rear section extermination section chassis 4. .

That is, as shown in FIG. 15, the front row extermination unit group 44 is connected to the front edge of the frame-shaped extermination unit chassis 4 via the connecting mechanism 5, while the rear row extermination unit group 4 is connected.
5 is connected to the rear end edge of the frame-shaped extermination part chassis 4 via a connection mechanism 5.

In other respects, the structure is the same as that of the first embodiment and the operation is the same.

In the case of this embodiment, however, since both the extermination section groups 44 and 45 are provided separately to the front and rear,
The same effect as the third embodiment can be expected.

FIG. 16 and FIG. 17 show a fifth embodiment of the present invention, in which both ends of the extermination part chassis 4 are
A resistance plate 61 having a surface perpendicular to the axis of the extermination section chassis 4 is provided.

In other respects, the structure is the same as that of the first embodiment and the operation is the same.

However, when the tidal current in the work area is flowing in the extermination direction of the extermination section 6, by installing the resistance plate 61, the resistance plate 61 becomes a resistance in the lateral direction,
It is possible to prevent the extermination section 6 from moving laterally when the work mother ship 2 rolls. The resistance plate 61 is particularly effective when the extermination unit 6 is towed by a wire rope for work. When the tidal current in the work area flows in the direction orthogonal to the extermination direction of the extermination unit 6, the resistance plate 61 has the opposite effect, and therefore the resistance plate 61 is preferably removable.

FIG. 18 shows a sixth embodiment of the present invention, in which the motor 35 is built in the shaft center of the brush 33.

That is, as the brush 33, as shown in FIG. 18, a brush whose diameter is enlarged and the inside of the shaft is hollow is used, and the brush casing 34 is provided inside the brush 33.
The motor 35 fixedly installed in the is inserted. The brush 33 is directly connected to the motor 35.

In other respects, the structure is the same as that of the first embodiment and the operation is the same.

By incorporating the motor 35 in the axial center portion of the brush 33, the brush casing 34 can be downsized to reduce the weight of the extermination portion 6, and the gap between the adjacent brushes 33 can be eliminated. Therefore, the structure of the extermination unit 6 can be simplified.

FIG. 19 shows a seventh embodiment of the present invention, in which each operating section can be automated in order to perform the work smoothly.

That is, as shown in FIG. 19, the underwater camera 71 and the acoustic sonar 7 are provided on the ship body 7 of the work mother ship 2.
2, the extermination section chassis 4 is provided with an inclination sensor 73 and a pressure sensor 74, the coupling mechanism 5 is provided with an angle sensor 75, and the extermination section 6 is further provided.
Is provided with an acceleration sensor 76.

The underwater camera 71 confirms the extermination status without confirming the sea bottom to be exterminated, when confirming the work starting point of the work mother ship 2 to correct the position, or without diving the diver. It is used for cases and the like, and the video can be recorded on a VTR and left as a work record.

Further, the acoustic sonar 22 is used for knowing the depth of the sea bottom, and based on the information from this acoustic sonar 72, the tilt of the arm 40 is removed so as to have an appropriate angle. The height of the partial chassis 4 is determined.

The inclination sensor 73 is used to know the inclination of the extermination section chassis 4.
By using the information from the inclination sensor 73, the ship cranes 24, 25 can be operated smoothly.

Further, the pressure sensor 74 can know the depth from the sea surface of the extermination part chassis 4 from the pressure of seawater. By using the information from this pressure sensor 74, the arm 40 The tilt can be easily adjusted to an appropriate angle.

Further, the angle sensor 75 is provided on the bracket 39 at the base end of the arm 40 so that the angle of the arm 40 can be detected. By confirming the information from the angle sensor 75, the angle sensor 75 can be detected. It is possible to constantly monitor whether or not the inclination is at an appropriate angle.

Further, the acceleration sensor 76 is attached to the brush casing 34, and the acceleration sensor 76 is attached.
When the brush 33 comes into contact with an obstacle, this information can be promptly known from the information from.

The information from each of the sensors 73, 74, 75 and 76 is not only displayed on a meter or the like but also input to a programmable controller to calculate a numerical value that optimizes the height and inclination of the extermination section chassis 4. By using the calculation results, the ship crane 2
4, 25 are automatically controlled.

Further, the number of rotations of each motor 35 can be confirmed in real time, and by knowing the load condition of the brush 33 based on the result, the extermination state of seaweed can be estimated. .

In other respects, the structure is the same as that of the first embodiment and the operation is the same.

However, it is difficult to directly check the condition of the extermination part 6 in the sea and the sea bottom because the seaweed extermination work is performed on the sea, but as in this embodiment, each operation part is difficult. By automating, the disinfection work can be performed safely and surely without diving the diver.

FIG. 20 shows an eighth embodiment of the present invention, in which seabed contact members 81 for grounding to the seabed are provided at both ends of the extermination part chassis 4, respectively.

That is, this seabed grounding member 81 is designed to be grounded to the seabed when the positioning of the extermination part chassis 4 in the sea is not required, and its lower end has a tip end as shown in FIG. A ski-shaped sliding plate 81a that is curved upward is fixedly installed. The sliding plate 81a makes it possible to easily ride over steps and irregularities on the sea floor. The sliding plate 81a is made of a material such as metal, plastic or wood, but a wheel having a large diameter may be used instead of the sliding plate 81a.

Since the extermination unit chassis 4 can be positioned without operating the expulsion unit chassis 4 with the ship cranes 24 and 25, even if the work mother ship 2 shakes due to waves or swells, the expulsion unit is removed. There are few problems that the chassis 4 shakes and the extermination efficiency decreases. This effect can be more reliably obtained by not connecting the extermination part chassis 4 directly to the ship cranes 24, 25 but by connecting them via a wire rope or the like.

FIG. 21 shows a ninth embodiment of the present invention. For example, one second seabed grounding member 82 is provided in the middle portion of the extermination part chassis 4 in the eighth embodiment. It was done like this.

That is, the seabed contact member 82 is shown in FIG.
