gate

By designing a pressure relief component on the gate, the water flow pushes the guide plate to automatically open the pressure relief groove, solving the problem of uneven force on the gate plate and achieving safe and stable operation of the gate.

AI Technical Summary

⚠Technical Problem

When a hydropower plant gate is opened to release water, uneven water pressure can cause the gate plate to bend and deform easily, resulting in uneven stress and affecting safe and stable operation.

⚗Method used

A gate with a pressure relief component was designed. The flowing water pushes the guide plate to move upward, automatically opening the pressure relief groove and dispersing the impact force of the water flow. Through the connection between the pressure relief component and the gate plate, the impact force below is evenly distributed on the gate plate, alleviating the problem of uneven water pressure.

🎯Benefits of technology

It effectively alleviates uneven pressure on the gate plate, reduces torsional force, avoids deformation or breakage of the gate plate, and improves the safety and stability of the gate.

Abstract

This invention relates to a gate, comprising a gate frame, a gate panel, and a pressure relief assembly. The gate panel has multiple spaced pressure relief grooves at one end in a first direction. The pressure relief assembly includes a fixed sleeve, a sliding sleeve, and a water guide plate. The sliding sleeve is slidably mounted on the gate panel and corresponds to the pressure relief grooves to block at least a portion of them. One end of the water guide plate is connected to one end of the sliding sleeve. The distance between the water guide plate's water-facing surface and the sliding sleeve gradually increases from one end to the other. Both the sliding sleeve and the water guide plate are slidably connected to the fixed sleeve. This invention utilizes the force of flowing water on the water guide plate to push it upwards, automatically opening the pressure relief grooves below the gate panel. This alleviates the continuous impact of high water pressure on the lower part of the gate panel. Furthermore, through the connection between the pressure relief assembly and the gate panel, the impact force on the lower water guide plate is evenly distributed from bottom to top onto the gate panel, solving the problem of excessive localized stress on the lower part of the gate panel and reducing its torsional force.
