Common drainage devices include gates, spillways, overflow weirs, etc. Among them, the gate is a door-type structure that can be opened or closed. The water level and flow can be adjusted by controlling the opening of the gate; the drainage device plays an important role in water conservancy projects and can help maintain the stability and safety of water conservancy facilities; There will be some man-made garbage and debris, such as discarded water bottles, in small rivers and lakes near cities.

The first intercepting plate 313 and the second intercepting plate 322 are away from the second filtering transverse plate 321. A synchronous connecting plate 73 is provided on the side. When the first filtering transverse plate 312 is lifted and lowered by the first lifting mechanism 4, the synchronous connecting plate 73 is used to drive the second filtering transverse plate 321 to be lifted and lowered synchronously.

Under the action of the first driving member 54, the first driving member 54 drives the first driving gear 55 to rotate, and the first driving gear 55 drives the first driven gear 56 to rotate through the chain, so that the lifting screw rod 52 rotates, and then the first interception plate 313 connected to the lifting screw rod 52 is lifted, thereby realizing the lifting of the filter device 3. During the lifting process, a U-shaped interception space is formed between the second interception plate 322 and the second filter horizontal plate 321 to intercept garbage and debris when the second filter horizontal plate 321 is lifted, and the water flows out from the second filter hole. The second filter mechanism 321 is then turned around by the second driving gear 74, and the second driving gear 74 drives the second driven gear 75 to rotate through the chain, thereby driving the turning roller 76 connected to the second driven gear 75 to turn over, so that the second filter transverse plate 321 with the turning roller 76 as the axis turns over. At the same time, since the two ends of the third driving member 81 are respectively hinged to the first intercepting plate 313 and the second intercepting plate 322, the fixed end of the third driving member 81 swings downward, and the movable end of the third driving member 81 contracts, thereby assisting in driving the second filter transverse plate 321 to turn over, thereby realizing the turning action of the second filter transverse plate 321, so that a dumping port 6 is generated between the second filter transverse plate 321 and the first filter transverse plate 312. The staff uses a tool to wait for the second filter mechanism 32 to turn over at the dumping port 6 position, so that the garbage and debris are poured out from the dumping port 6, thereby improving the cleaning efficiency of the garbage and debris in the filter device 3 at the sluice.

[0050] The embodiment of the present application also discloses a method for draining water from a water conservancy dam.

[0051] A method for draining water from a water conservancy dam, based on the above-mentioned device for draining water from a water conservancy dam, comprises the following steps: S1: Open the sluice gate 2, start the first lifting mechanism 4, and use the first lifting mechanism 4 to lift the sluice gate 2 between the two groups of dam infrastructure 1, so as to drain the water in the river channel; S2: Filtering garbage and debris. After the sluice gate 2 is opened, water flows out from the bottom of the sluice gate 2. The filtering device 3 located on one side of the sluice gate 2 intercepts and collects the garbage and debris brought by the water flow. S3: closing the sluice gate 2, starting the first lifting mechanism 4, and using the first lifting mechanism 4 to lower the sluice gate 2 between the two groups of dam infrastructure 1, so that water is stored in the river channel; S4: garbage and debris cleaning, start the second lifting mechanism 5, use the second lifting mechanism 5 to lift the first filter mechanism 31 on one side of the sluice gate 2, and the second filter mechanism 32 is synchronously lifted following the first filter mechanism 31, so that the garbage and debris in the first filter mechanism 31 and the second filter mechanism 32 are lifted out of the water together, and then the staff uses the tool to wait for the second filter mechanism 32 to flip over at the dumping port 6. After the second filter mechanism 32 is flipped, some garbage and debris enter the tool from the dumping port 6, and other staff can use cleaning tools to clean the garbage and debris that have not been poured out from the first filter mechanism 31 and the second filter mechanism 32 to the dumping port 6, and pour it into the tool from the dumping port 6, thereby realizing the cleaning of garbage and debris.
