Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a water gate with a two-stage door installed in a river, particularly a water level adjustable water gate having a device for engaging and disengaging an upper door and a lower door. Regarding.

[Conventional technology]

BACKGROUND ART Conventionally, a two-stage water gate is known as a water gate that can adjust the water level when the water is full.

10A to 10D are cross-sectional views schematically showing different states of a conventional two-stage water gate, in which a lower door 102 is integrally attached to a frame 101, and an upper door 103. is the lower door 10 inside the frame 101
2, and an upper door 103 is driven by an elevating shaft 104. In the frame 101,
Upper and lower stoppers 105 and 106 are provided to restrict the upper and lower limits of movement of the upper door 103. Note that 107 is a water gate bottom, and 108 is a groove formed in the water gate bottom 107.

In this conventional two-stage water gate, when used at half-water level, as shown in Figure 10A,
The lower door 102 and the upper door 103 are overlapped to form the lower door 1.
The lower end of the lower door 102 is in close contact with the groove 108 of the water gate bottom 107, and when used at full water level, the upper door 103 is pulled up by the lifting shaft 104, and the lower end of the lower door 102 is brought into contact with the groove 108 of the water gate bottom 107. groove 108
The lower door 102 and the upper door 103 are in close contact with each other, and the lower door 102 and the upper door 103 are shifted from each other.

In addition, when pulling up both doors, if the lifting shaft 104 is further pulled up, the upper end of the upper door 103 comes into contact with the upper stopper 105 of the frame body 101, and the upper door 103 and the upper end of the frame are brought into contact with each other. body 1
The lower door 102 integrated with 01 rises, and the 10th
As shown in Figure D, it is in a fully open state.

[Problems to be Solved by the Invention] However, the conventional two-stage water gate shown in FIG. 10 has the following problems.

() In the event of an emergency such as a rise in water due to rain, it takes time to fully open the flood gates, making it impossible to take immediate action.

That is, for example, in order to change the water gate from the half-water level shown in FIG. 10A to the fully open state shown in FIG. and the state shown in FIG. 10C, so it takes time to fully open the flood gate.

() The moving distance of the elevating shaft 104 becomes longer, leading to an increase in operating time, and it is necessary to secure a large space necessary for moving the elevating shaft 104.

For example, assuming that the heights of the upper door 103 and the lower door 102 are the same, the height of the doors 102 and 103 must be changed in order to go from the half-water level state shown in FIG. 10A to the fully open state shown in FIG. 10D. Requires three times the travel distance.

() It takes time to close the water gate.

When closing the water gate, the lower end of the lower door 102 must be in close contact with the groove 108 of the water gate bottom 107. However, if the groove 108 is clogged with earth and sand, the lower door 102 and frame 101 must be closed.
The lower end of the lower door 102 can be cut into the groove 108 by its own weight alone.
It cannot be kept in close contact with the For this reason, it is necessary to apply pressure to the lower door 102 from above. For example, in order to change from the fully open state shown in FIG. 10D to the full water level state shown in FIG. Through the states shown in
In the state shown in FIG. 10A, the upper door 103 is pressed from above by the lifting shaft 104, and the upper door 103
The lower end of the lower door 102 is brought into close contact with the groove 108 via the frame 101 by abutting the lower end of the lower stopper 106 of the frame 101, and then the upper door 103 is pulled up again, as shown in FIG. 10B. must be in state. In other words, regardless of whether the water is at half-water level or at full-water level,
The lower door 102 must be lowered once to the lower limit position, which takes extra time.

An object of the present invention is to provide a water level adjustable water gate that can solve the above problems.

As the whole is lowered relative to the first rack rod 5, the operating rod 23 is lowered along the first rack rod 5 (see FIG. 8). In conjunction with this, as shown by solid lines in FIG.
6 is lowered, the crank plate 22 rotates clockwise in the figure around the shaft 20, the rack engagement pin 19 engaged with the crank plate 22 moves to the left in the figure, and the second rack rod 8 The rack pin 8b and the rack engagement pin 19 can be engaged with each other, and the engagement/disengagement device 9 is in an engaged state. That is, crank plate 2
2 acts as drive direction changing means. In this state, the locking pin 30 is reinserted into the operating frame 27 to prevent the relative positions of the operating device 10 and the first rack rod 5 from shifting.

In this state, when the first rack rod 5 is raised by the lifting drive device 6, the operating device 10 and the engagement
The entire detachment device 9 rises, and the upper door 2 fixed to the engagement/disengagement device 9 rises, and the rack engagement pin 19 comes into contact with the rack pin 8b of the second rack bar 8. The lower door 3 connected to the lower door 3 also rises. Therefore, from the state in which the upper door 2 and the lower door 3 are overlapped, both doors can be directly raised as one, and the water gate can be quickly brought into a fully open state.
That is, there is no need to wait until the upper end of the upper door 2 comes into contact with the upper stopper 14a of the frame 11, as in conventional water gates.

Also, when the lower door 3 is brought into close contact with the water gate bottom 13, the engagement/disengagement device 9 is engaged as described above, regardless of the positional relationship between the upper door 2 and the lower door 3. In this state, the positional relationship between the upper door 2 and the lower door 3 is fixed, so by lowering the first rack rod 5 using the elevating drive device 6 in this state, the upper door 2 and the lower door 3 are moved. are lowered together, and the lower end of the lower door 3 can be quickly brought into close contact with the water gate bottom 13. That is, unlike conventional water gates, there is no need to bring the lower end of the upper door 2 into contact with the stopper 14 of the frame 11 and then raise the upper door 2 to a desired height again.

In addition, when changing the positional relationship between the upper door 2 and the lower door 3, the locking pin 30 of the operating device 10 is inserted into the operating frame 27.
When the handle 29 is pulled up, the operating rod 23 rises, and in conjunction with this, the plate-shaped bodies 24, 25 and the link rod 26 are moved up as shown by the dashed line in FIG.
rises, the crank plate 22 rotates counterclockwise in the figure around the shaft 20, the locking pin 19a engaged with the long groove 22a of the crank plate 22 moves to the right in the figure, and the second rack bar 8 rack pin 8
b is disengaged from the rack engagement pin 19, and the engagement/disengagement device 9 enters the disengaged state. Note that the locking pin 30 is reinserted into the operation frame 27, and the operation frame 27 is
and the operating rod 23 so that their relative positions do not deviate.

Therefore, if the first rack rod 5 is raised by the lifting drive device 6 in this state, only the upper door 2 will be raised.
By stopping the elevating drive device 6 at a desired position, the amount of overlap between the upper door 2 and the lower door 3 can be adjusted. When the handle 29 is pulled down after adjustment,
Since the rack engagement pin 19 is passed through between the rack pins 8b at a predetermined position, the relative positions of the upper door 2 and the lower door 3 can be fixed. Therefore, the upper door 2 and the lower door 3 can be fixed in any overlapping state, and the water gate can be opened and closed while the height of both doors of the water gate is fixed at the desired height. If the water level is predetermined, there is no need to set the height of both gates each time the gate is opened and closed, improving operability.

〔Effect of the invention〕

As described above, according to the present invention, the following effects can be obtained.

() Regardless of how the upper and lower doors overlap, it is possible to immediately raise both doors as one unit, so even if there is an urgent need to spray water due to increased water due to rain, etc., you can respond quickly. .

() Without lowering the upper door to the lower limit position,
Since the lower door can be brought into close contact with the bottom of the water gate, the door can be closed quickly.

() The water gate can be opened and closed while keeping the height of both gates constant, improving operability.

() Since the operating rod that operates the engagement and release device between the upper door and the lower door moves along the first rack rod, there is no need for extra space to operate the release device, and there is no need for inconvenience. I never touch it.

() Easy to operate, engaging and disengaging operations can be performed in one place.

() The moving distance of the lifting axis is shortened, and less space is required for moving the lifting axis.
