Water stop rubber protection device for flat steel gate

Abstract

The invention relates to a water stop rubber protection device for a flat steel gate, in particular to water stop rubber of the flat steel gate and starting and closing of the gate. The device is characterized in that a hydraulic oil cylinder flange is welded on a door frame; the door frame is fixedly provided with a hydraulic oil cylinder through the hydraulic oil cylinder flange; the piston rodend of the hydraulic oil cylinder is provided with a guide wheel; the door frame is provided with a hole in which the piston rod and the guide wheel of the hydraulic oil cylinder are inserted; the piston rod and the guide wheel of the hydraulic oil cylinder are pressed against the wall of a guide channel beyond the water stop rubber so as to separate the water stop rubber from the wall of the guide channel; and the hydraulic oil cylinder is connected with a hydraulic pump station on a platform through a high pressure corrosion-resistant hose. The device can protect the water stop rubber and ensure reliable sealing between the water stop rubber and the guide channel, so the leakage of the steel gate is smaller; the device can effectively reduce the starting and closing force of the gate; and the device can greatly save the horizontal pressure charging time so as to improve the working efficiency.

Description

technical field [0001] The invention relates to a water-stop rubber protection device for a plane steel gate, in particular to the water-stop rubber for a plane steel gate and the opening and closing of the gate. Background technique [0002] The water-stop rubber is an important part of the plane steel gate. Through its sealing effect with the gate guide groove, the gate can intercept the water. The opening and closing methods of general plane gates are divided into static water opening and closing and dynamic water opening and closing. [0003] The plane steel gate consists of a gate guide groove, a steel gate body and a water-filled balance valve. It is suitable for water intake, drainage, sewage treatment and other projects in power plants. It is installed in conjunction with the gate guide groove at the water inlet of the pump station or the inlet part of the pipeline, the water outlet, etc. [0004] The plane steel gate has a simple structure, takes up little space a...

AI Technical Summary

Problems solved by technology

[0005] In the prior art, the water-stop rubber has no protection device during the opening and closing process, and the water-stop rubber is easy to rub violently with the guide groove wall under the action of water pressure, which intensifies the opening and closing force while causing the water-stop rubber to overturned or even damaged

Especially in water with poor water quality such as a lot of sundries and sand particles, slight friction can cause strain and scratches on the water-stop rubber, resulting in poor sealing and increased leakage
