The reinforcing ribs 4 play a role in strengthening the valve plate 3, and the valve plate 3 can be strengthened to resist the strong pressure brought by the water flow. The bottom inner wall of the valve frame 1 is provided with a bottom groove 5. The bottom end of the valve plate 5 is connected with a sealing gasket 6, and the sealing gasket 6 matches the bottom groove 5. The sealing gasket 6 is embedded in the bottom groove 5 to make the valve plate 3 and the valve frame 1 sealed, so as to avoid water seepage at the connection between the valve plate 3 and the valve frame 1.

[0021] A fixing frame 7 is arranged on the top of the valve frame 1, and the fixing frame 7 plays a fixing role. A rotating shaft 8 is connected to the middle part of the fixing frame 7 through a bearing, and the rotating shaft 8 can rotate in the fixing frame 7. A servo motor 9 is arranged on one side of the fixing frame 7. A brake device is arranged in the servo motor 9, which can keep the brake in a braking state when the work stops. The output end of the servo motor 9 is connected to the rotating shaft 8, and the rotating shaft 8 can be driven to rotate by the servo motor 9. The outer walls on both sides of the rotating shaft 8 are key-connected with a winding drum 10, and the winding drum 10 plays a winding role.

[0022] The outer wall of the winding drum 10 is wrapped with a steel cable 11, and one end of the steel cable 11 away from the winding drum 10 extends downward through the valve frame 1 and is connected to the valve plate 3. The steel cable 11 plays a connecting role. When it is necessary to open the gate, the servo motor 9 drives the rotating shaft 8 to rotate, and the rotation of the rotating shaft 8 drives the winding drum 10 to rotate so that the winding drum 10 reels the steel cable 11. The valve plate 3 at the bottom end of the steel cable 11 is reeled up by the steel cable 11, thereby realizing the gate opening work. When closing the gate, the servo motor 9 is reversed to relax the steel cable 11, and the valve plate 3 automatically slides down due to the gravity of the valve plate 3 to close the gate. A filter plate 12 is connected to the bottom outer wall of one side of the valve frame 1 through a fixing bolt. The filter plate 12 can be installed or disassembled by tools for use in different situations. The filter plate 12 plays a filtering role and can block the solid garbage in the river, thereby facilitating the collection and cleaning of the garbage.

[0023] A fixed box 13 is connected to the edge of one side of the filter plate 12 away from the valve frame 1. The interior of the fixed box 13 is connected to a screw 14 through a bearing. The outer wall of the screw 14 is threadedly connected to a moving block 15. A forward and reverse motor 16 is arranged on one side of the fixed box 13. The output end of the forward and reverse motor 16 is connected to the screw 14. The forward and reverse motor 16 can drive the screw 14 to rotate. The rotation of the screw 14 drives the moving block 15 to move. A protective cover 17 is provided on the outer sleeve of the forward and reverse motor 16. The protective cover 17 plays a role in protecting the forward and reverse motor 16 to prevent water from entering and causing damage to the motor.

The forward and reverse motor 16 can drive the screw 14 to rotate, and the rotation of the screw 14 drives the moving block 15 to move. The moving block 15 moves and drives the cleaning brush 24 to move, so as to clean the surface of the filter plate 12, thereby avoiding the clogging of the filter plate 12. At the same time, the garbage in the middle of the river channel can be pushed to the edge for the convenience of staff to salvage and clean it. The inner wall of the bottom groove 5 is arranged with a support spring 18, and the support spring 18 plays a rebound role and is compressed and contracted. The top of the support spring 18 is connected with a top plate 19, and the outer wall of the top plate 19 is close to the bottom groove 5. When the gate plate 3 is lifted, the support spring 18 rebounds and drives the top plate 19 to rebound upward, so that the top plate 19 and the inner wall of the bottom end of the valve frame 1 are in the same straight line, thereby preventing the silt in the river channel from falling into the bottom groove 5 and making it difficult to clean.

[0025] A movable groove 20 is provided on the outer wall of the bottom end of the sealing gasket 6, and the movable groove 20 plays a movable role.

The valve plate 3 at the bottom end of the steel cable 11 is lifted up by the steel cable 11 to open the gate. When closing the gate, the servo motor 9 reverses to relax the steel cable 11, and the valve plate 3 automatically slides down due to the gravity of the valve plate 3 to close the gate. The reinforcing rib 4 strengthens the valve plate 3 to strengthen the valve plate 3 to resist the strong pressure brought by the water flow. The sealing gasket 6 is embedded in the bottom groove 5 to seal the valve plate 3 and the valve frame 1 to avoid water seepage at the connection between the valve plate 3 and the valve frame 1. The filter plate 12 can be installed or disassembled by tools for use in different situations. The filter plate 12 plays a filtering role and can block the solid garbage in the river channel, thereby facilitating the collection and cleaning of the garbage. The machine 16 can drive the screw 14 to rotate, and the rotation of the screw 14 drives the moving block 15 to move, and the movement of the moving block 15 drives the cleaning brush 24 to move, so as to clean the surface of the filter plate 12, thereby avoiding the clogging of the filter plate 12. At the same time, the garbage in the middle of the river channel can be pushed to the edge for the convenience of the staff to salvage and clean it. When the gate plate 3 is lifted, the support spring 18 rebounds and drives the top plate 19 to rebound upward, so that the top plate 19 and the bottom inner wall of the valve frame 1 are in the same straight line, thereby avoiding the silt in the river channel from falling into the bottom groove 5 and being difficult to clean. When the valve plate 3 is closed, the sealing gasket 6 is embedded in the bottom groove 5, and the movable frame 21 and the second spring 21 are compressed and contracted into the movable groove 20. When the valve plate 3 is lifted, the second spring 21 rebounds and drives the movable frame 21 and the cleaning roller 23 to pop out. The cleaning roller 23 can be driven by the water flow to rotate, so that the bottom inner wall of the valve frame 1 can be cleaned, thereby avoiding the accumulation of silt and causing a gap at the bottom of the valve frame 1 when it is closed.
