Background

A sluice for draining flood water, also called a drainage sluice. Is usually arranged at the outlet of the flood area for draining water to the river. Drainage gates on irrigation channels are used to remove excess water from the irrigation channel, such as during flood periods to remove floodwaters from the area of the canal system where the water is collected, commonly referred to as a drainage gate. The water return valve is positioned at the tail end of the channel and used for draining accumulated water in the channel and facilitating the maintenance of the channel, and is called as a water return valve. The drainage gate is also called a tide barrier gate and is built at the outlet of the coastal drainage river channel.

Existing drainage gates are generally vertically sliding, but require a large motor or a complex starting device to overcome the resistance of water, the flow of water or the gravity of the gate to lift the gate, and when the drainage gate is lifted and lowered, the pressure and impact force of the water flow are too large, so that the drainage gate is subjected to large resistance in the process of opening and closing.
