Steel gate and operating method thereof

Abstract

The invention provides a steel gate and an operating method thereof, relating to a turning-down steel gate and the operating method thereof. The invention provides the steel gate and the operating method thereof, and the steel gate can reduce operating energy consumption and can prevent a gate body from being vibrated. The steel gate comprises a gate shaft, a gate body, a gate body driving device, a controller, rubber dam bags and a rubber dam bag charging and discharging control device, wherein the gate body intercepts a water channel; the gate body is hinged with the gate shaft arranged at the bottom of the water channel; the rubber dam bags are fixedly connected with the top part of the gate body; the rubber dam bags and the top part of the gate body are in watertight seal to form a water barrage structure on the top of the gate body; and the rubber dam bag charging and discharging control device is connected with the controller. The operating method comprises the following steps of: 1) injecting water in the rubber dam bags until the rubber dam bags are full when the steel gate is in a vertical state; 2) storing water in upstream of the steel gate to a height at the top edge of the rubber dam bags; 3) making the rubber dam bags gradually unloaded when discharging water, and gradually reducing the height. According to the steel gate and the operating method thereof, the service life of the steel gate can be greatly prolonged.

Description

technical field [0001] The invention relates to a downward-turning steel gate and a working method thereof. Background technique [0002] At present, in water conservancy and hydropower projects, urban waterways, landscape waterways, environmental protection waterways and irrigation waterways, a large number of downward-turning steel gates are used. Its advantage is that it takes up little space. When releasing water, the net (clear) water at the top first flows downstream, using downstream water quality control and water flow control. However, the structure of this kind of gate is that the bottom axis rotates (the gate body generally moves downstream); the upstream water level is 2-3 meters high, and the static pressure on the gate body is extremely high. When working, if only a small amount of water needs to be discharged as the design requires, a large amount of electric energy is also required to drive the gate to dump and release water, reset and store water. If the ...

[0003] In addition, when the rigid door body is tilted to release water, when the water flow falls on the edge of the door body, a low-pressure sealed chamber will be formed between the inside of the water flow and the outside of the door body (towards the downstream surface of the door body). The resonant frequency is the same, which will cause the door body to resonate and damage the connection structure of the door body
