Description

Technical Field

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

[0002] Gates are control facilities used to close and open water discharge channels. They are an important part of water conservancy structures and can be used to intercept water flow, control water levels, regulate flow, and discharge sediment and floating objects.

[0003] In the process of opening and closing by lifting, the existing gate reserves a distance between the outer frame and the gate to ensure the vertical movement of the gate plate and prevent impurities from completely blocking the gap between the two. However, the gate will swing within the distance during lifting, which may easily cause the gate plate to collide or resist the outer frame. This phenomenon will increase the damping of the gate plate during lifting. Therefore, there are great limitations in actual use and there is room for improvement. Utility Model Content
