Description

Technical Field

[0001] This utility model relates to the field of gate equipment technology, and in particular to a steel gate with an anti-collision structure. Background Technology

[0002] Gates are control facilities used to close and open water discharge channels. They are an important component of hydraulic structures and can be used to intercept water flow, control water level, regulate flow, and discharge sediment and floating debris. Currently, steel gates usually use a lifting structure to move the gate vertically to achieve the function of intercepting water flow. However, the anti-collision structure of current steel gates has limited anti-collision effect. Large rocks and other objects in the rapid water flow can easily damage the gate when they hit it, making it difficult to improve the protection of the gate. Utility Model Content
