The weir gate body of the rotary weir gate can be driven to rotate by hydraulic equipment, etc., so that the overall height of the weir gate body can be adjusted, the discharge volume can be adjusted, and water backflow can be prevented during use.

[0003] For example, the invention patent: "An integrated hydraulic rotary anti-backflow weir gate", with the announcement number "CN113737745A", designs the cylinder bracket and the weir gate outer frame, so that the cylinder can be installed on the weir gate outer frame, thereby eliminating the need for a separate wall to install the cylinder. The weir gate can be installed and embedded at a construction site where it is not suitable to use two cylinders for two-way support at both ends of the weir gate or to install the cylinder in the center of the weir gate. However, during the implementation of this patent, the weir gate body is driven to rotate by controlling the extension and contraction of the cylinder. During the driving process, the inclination angle of the cylinder needs to be adjusted so that the cylinder can directly push or pull the weir gate body to rotate. It is not only difficult to install the cylinder firmly, but also inconvenient to drive the weir gate body to rotate stably. Therefore, a new integrated hydraulic anti-backflow rotary weir gate is urgently needed to solve the above problems. Utility Model Content
