Description

Background Art

Gates are control facilities used to close and open water discharge channels. They are an important part of water conservancy projects and can be used to intercept water flow, control water levels, regulate flow, and discharge sediment and floating objects.

In the past, when the flood control gates of water conservancy projects were opened, the filter plates in front of the flood control gates were often lifted up at the same time, and the filter plates were erected in front of the flood control gates to block foreign objects. When the flood control gates lifted up the filter plates, the filter plates were installed on the bottom of the riverbed through chutes, and the chutes were immersed in river water for a long time, which led to a lot of silt inside the chutes. The silt in the chutes would hinder the sliding of the filter plates, which would greatly increase the resistance of the flood control gates to move the filter plates when the flood control gates were opened, and increase the time to open the flood control gates, making it inconvenient to discharge flood water.

Under the action of gravity, the roller pulls the drum downward and drives the protrusion to contact the filter plate. At the same time, when water flows, the fan blades are driven by water to rotate, so that the drum drives the protrusion to rotate, so as to facilitate the drum to drive the protrusion to get stuck in the filter holes on the filter plate, so that the protrusion squeezes the blockage in the filter holes of the filter plate, and creates a gap between the blockage and the filter holes of the filter plate, so that water can push away the blockage, thereby preventing the blockage from affecting the water passing through the filter holes of the filter plate.

When water drives the fan blades to rotate, the fan blades drive the drum to rotate, so that the drum drives the convex blocks and with the help of the filter holes on the filter plate, the drum has a pulling force on the filter plate to one side, thereby assisting the movement of the filter plate. When the workers lift the gate body, the filter plate has an auxiliary force to lift the gate body upward, which makes it easier for the workers to open the gate body and reduces the resistance to the opening of the gate body.
