Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy gates, in particular to a water conservancy gate structure. Background Art

[0002] Hydraulic gates are an important control device in water conservancy projects, mainly used to regulate water flow, control water level, and realize water storage or flood discharge. They are usually installed at the water inlet and outlet of waterways, rivers, reservoirs, irrigation systems or hydroelectric power stations. According to different structures and functions, hydraulic gates can be divided into many types, mainly including the following:

[0003] Plane gate: This is one of the most common types. The gate is a flat plate that moves up and down along a horizontal or nearly horizontal track to close or open a waterway.

[0004] Radius gate: The gate is arc-shaped and rotates around a fixed hinge point. It is suitable for waterways with large spans, can better resist water pressure and has good sealing performance.

[0005] Miter gate: It consists of two gates in the shape of a miter, usually used in large locks or dams. The two doors can be closed separately or simultaneously, providing more flexible control.

[0006] Flap gate: It opens and closes automatically by the weight of the gate or water pressure. It is suitable for small channels or low head applications and is easy to operate.

[0007] Rapid gate: designed to close quickly in an emergency to prevent water hammer effect or sudden flooding, commonly found at the outlet of the water diversion pipeline of a hydropower station.

[0008] Maintenance gate: used for maintenance or inspection when the normal gate is closed to ensure that the normal operation of the main project is not affected.

[0009] The control system of the hydraulic gate can be manual, electric, pneumatic or hydraulically driven, and is usually equipped with remote monitoring and automated operating systems to achieve precise control and improve safety. In an emergency, the emergency brake control method and process of the hydraulic gate are crucial to respond quickly and prevent disasters.
