[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. They are also called water projects. Water is a precious resource indispensable to human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flows, prevent floods and waterlogging disasters, and regulate and distribute water to meet people's needs for water resources in life and production. Water conservancy projects require the construction of different types of hydraulic structures such as dams, dikes, spillways, sluices, water inlets, channels, ferries, rafts, fishways, etc. to achieve their goals.

[0003] At present, some of the sluice gates used in water conservancy projects are manually opened and closed gates or manually operated mechanical power opened and closed gates, which cannot automatically control the opening and closing of the gates, making the opening and closing of the gates more troublesome, the gate opening and closing work efficiency is low, and the practicality is insufficient. Utility Model Content
