[0024] In water conservancy projects, gates are used to control the flow and flow of fluids in reservoirs / waterways. Generally, gates move vertically driven by a drive mechanism. The flow of water is controlled by the distance between the gate and the bottom of the waterway. When the distance is zero, the gate cuts off the flow of water. If there is foreign matter between the gate and the bottom of the waterway, it will affect the closure of the gate and may even damage the gate.
