Description

Technical Field

[0001] The utility model relates to the technical field related to gates, in particular to a flip steel dam gate with a double opening and closing mechanism. Background Art

[0002] A gate is a common water conservancy engineering facility used to regulate water flow, control water level, prevent floods or divert water flow. It is usually composed of one or more movable plates that can be opened or closed. The degree of opening of the gate plate can be adjusted as needed to control the flow rate and water level of the water.

[0003] In the prior art, the steel dam gate is fixed on the pier, and a hinge seat is fixedly installed on the side surface of the steel dam gate. The hinge seat and the top of the bottom shaft are hingedly connected, and the bottom end of the bottom shaft and the piston rod at the output end of the hydraulic hoist are welded. The hydraulic hoist drives the piston rod to support the bottom shaft, and the bottom shaft supports the steel dam gate to open it. When the steel dam gate is closed, the steel dam gate is closed in a free fall state due to the force of the water flow and its own gravity.

[0004] However, when the steel dam gate reaches the pier, the momentum of the steel dam gate is large, which causes the steel dam gate to produce an impact force on the pier. When the steel dam gate is closed multiple times, the steel dam gate will damage the pier, causing the steel dam gate to become unstable on the pier. Utility Model Content
