Description

Detailed Description of the Invention 3. Detailed Description of the Invention [Field of Industrial Application] The present invention relates to an opening/closing device (movable weir) provided in a water gate of a river or various reservoirs.

[Conventional technology]

A conventional water gate opening/closing device has a structure in which a single gate is moved upward by a vertical device to allow water to flow from below the gate.

[Problem that the invention seeks to solve]

However, as mentioned above, with conventional water gate opening/closing devices, water can only be released from below by raising the gate.
There is a problem in that if there is a request to obtain warm water from above or to remove garbage, water, etc. floating on the water by spraying water, the request cannot be met.

[Means for solving problems]

The present invention provides a water gate opening/closing device in which a gate is provided on a guide member so as to be vertically movable, and the gate is composed of an upper gate and a lower gate that can be stacked vertically with respect to the upper gate. The above conventional problems are solved by attaching a vertical device to move the upper gate up and down, and by providing a locking device between the upper gate and the lower gate to lock the lower gate to the upper gate. This is what I did.

[Sakuta] To fully close the water gate, the upper part of the lower gate is stacked on the lower part of the upper gate and lowered by the vertical device, so that the lower part of the lower gate touches the bottom of the water.

Furthermore, when water is to be discharged from below the gate, the lower gate is locked to the upper gate by the locking device, the entire gate is raised by the up/down device, and the lower gate is separated from the bottom of the water.

In addition, when water is to flow from above the gate, the upper gate is lowered below the water surface using a vertical device.

Furthermore, when discharging water from both the top and bottom of the gate, the upper gate is lowered and stacked on the lower gate, the lower gate is locked to the upper gate using a locking device, and the upper and lower gates are raised slightly from the bottom of the water. .

7. Connecting link 18 connected to the tip of this arm 17
, and the lock fitting 14 can be locked to a locking member 20 provided on the upper gate 3 by rotating it through an arm I9 fixed to the shaft 13 and having its tip connected to a connecting link 18. It is configured. Above operation lever 1
5 is attached to an operating spindle 16 by a sliding key 21, and the operating spindle 16 moves up and down within a cover vibe 22 provided on the operating lever I5.

Furthermore, the upper gate +-3 is provided with a vertical device 23 that moves the upper gate 3 up and down. This vertical device 23
The nut body 25 is rotated by the vertical handle 24, and the lower end is attached to the upper gate, so that the vertical handle 24 is rotated by the vertical handle 24.
When the two left and right nut bodies 25 are rotated by
The book drive threaded rod 26 is configured to move up and down synchronously.

A cover 27 is provided on the upper part of the upper gate 3 to cover the lower gate 2, and prevents water flowing out over the upper part of the upper gate 3 from directly falling into the lower gate 2. Further, a stopper screw 28 is attached to the upper gate 3 so as to be vertically adjustable and abuts against the upper surface of the lower gate 2 to stop the upper gate 3 from descending.

The operation of the gate opening/closing device will be explained.

In the closed state shown in FIG.
Also, since the upper gate 3 brings the sealing member 8.9 into close contact with the door stop 5a of the seal frame 5 and the lower gate 2 to make that part watertight, water does not flow into the upper gate. It does not flow out except when overflowing the water.

When water is to flow from below the lower gate 2, the up and down handle 24 is operated, the nut body 25 is rotated in the forward direction, and the upper gate 3 is pulled up together with the drive threaded rod 26. In this case, when the lock fitting 14 is locked to the locking member 20, the lock fitting 14 also locks the lock fitting! 4 is removed from the locking member 20, finally,
By engaging the lower member 34 of the upper gate 3 with the stopper 33, the lower gate 2 is pulled up following the upper gate 3, and the lower part is separated from the bottom of the water.

When water is to overflow, the nut body 25 is rotated in the opposite direction using the vertical handle 24, the upper gate 3 is lowered from the state shown in FIG. 1, and its upper part is lowered below the water surface. In this case, water flows over the cover 27 and falls to the downstream side of the lower gate 2. In addition, if the lock fitting 14 gets in the way in the above, operate the operating lever 15 to rotate the lock fitting 14 onto the lower gate 2, and then move the lock fitting 14 onto the lower gate 3.
(Locking member 20) is removed from the lifting surface.

Furthermore, when you want water to flow from above and below the gate, lower the upper gate 3 so that it overlaps the lower gate 2 as shown in FIG.
After operating the upper gate to lock it to another locking member 20 above, the upper and lower gates 3 and 2 are raised slightly from the bottom by operating the up-and-down handle 24.

As explained above, the water gate opening/closing device of the present invention includes an upper gate and a lower gate that can be stacked vertically with respect to the upper gate. In addition, a locking device is provided between the upper gate and the lower gate to lock the lower gate to the upper gate, so that the lower gate can be connected to the upper gate. Not only can you raise the water at the same time and discharge water from below the gate as before, but you can also lower the upper gate to allow water to overflow, or lower the upper gate and raise the lower gate to prevent them from overlapping. Water can be sprayed. Therefore, if you want to get warm water from the surface heated by the sun, get clean water that does not contain sludge at the bottom of the water, or want to remove garbage etc. by spraying water, etc.
It can meet a wide range of water discharge requirements.
