AI Technical Summary
The existing gate limit devices in hydropower stations cannot continuously synchronize the length of the steel rope winding and unwinding in the drive device, resulting in slight tilting of the gate that cannot be detected in time. Long-term use leads to severe wear and tear on the limit devices, rendering them ineffective.
A detection mechanism, including a signal sensor and a movable plate, is installed on the side wall. The signal sensor determines whether the door is tilted while moving on the connecting groove, and the movable plate is always moved outward by a torsion spring. Combined with the engagement and limiting of the rack and pinion, the door moves stably and the drive device is adjusted in time.
It enables timely detection and adjustment of the gate, avoids wear on the limit device, improves the limit effect, and ensures stable movement of the gate on the connecting groove.
