AI Technical Summary

Technical Problem

The natural deposition of silt will gradually fill the gap between the gate and the frame, affecting the normal lifting and lowering function of the gate, leading to water stop failure, reduced sealing performance, and even the inability of the gate to close completely, thus affecting the flood control effect and operational safety of the water conservancy project.

Method used

A sand-pushing mechanism is used to push the mud and sand at the guide rail to the center, and then a flipping scraper is used to remove it. The automatic sand removal is achieved by hydraulic drive, ensuring that there is no mud and sand accumulation at the bottom when the gate is closed, and avoiding movement interference.

Benefits of technology

Ensuring smooth and unobstructed closure of the gates improves operational reliability, guarantees sealing, avoids movement interference caused by sediment accumulation, and significantly enhances the operational safety and efficiency of water conservancy projects.

Abstract

This utility model relates to the field of steel dam gate technology, and in particular to a hydraulic steel dam gate with a sand-clearing structure. It includes a steel dam gate mechanism for sand clearing. The steel dam gate mechanism includes: a main component comprising guide rails fixed at both ends of the inner wall of a frame, with a gate slidably installed between the guide rails; and a sand-pushing component comprising a push plate located at the lower end of the inner wall of the frame, a guide frame fixed to the push plate and penetrating the frame, a shaft rotatably installed inside the outer end of the guide frame, and first hydraulic cylinders installed at both ends of the outer wall of the frame. A guide seat is fixed at the output end of the first hydraulic cylinder, and a guide groove is provided inside the guide seat, with the shaft located inside the guide groove. The sand is first pushed to the center by the sand-pushing mechanism, and then collected and removed by a flipping scraper. Automated sand clearing is achieved through hydraulic drive, ensuring no sand accumulation at the bottom when the gate is closed, thus guaranteeing sealing and avoiding motion interference, significantly improving operational reliability.
