[0002] A gate usually refers to a device used to control the flow of fluid or materials. It is often used in water conservancy projects, power projects, mining, metallurgy, chemical industry and other industries. It is usually an important component for controlling and regulating material flow.

[0003] The patent with announcement number CN217267314U discloses a lifting gate for water conservancy projects. In the embodiment, a servo motor, a gear, a first rack, a second rack, a first plug rod and a second plug rod are arranged, and the end is inserted into the limit hole to complete the fixation of the second plug rod and the first plug rod, which is beneficial to reduce the impact force of the water flow on the gate body and protect the gate body. It solves the problem of poor stability of the gate body due to the lack of a support structure on the back surface of the gate body.

[0004] However, the inventors have found that the motor is easily damaged when immersed in water for a long time, and the maintenance is relatively troublesome. Therefore, we have proposed a gate for water conservancy projects. Utility Model Content
