AI Technical Summary
When adjusting the gate position, the existing river closure gate is easily impacted by water flow pressure, which causes the connecting rod between the motor and the gate to deform.
A limiting structure is adopted, including components such as a fixing frame, a sealing cover, a fixing screw, a positioning plate and a torsion spring. The positioning and limiting of the positioning plate are achieved through the elastic connection and threaded connection of the torsion spring to avoid water pressure shock.
