Automatic switch of radial gate suitable for culvert

Abstract

The invention discloses an automatic switch of a radial gate suitable for a culvert, which comprises a control mechanism on a dam and is characterized by also comprising an arc access door and a main radial gate of the dam, wherein the arc access door is arranged in front of the dam and is close to a water source, the control mechanism comprises an air switch, a contraction steel cable, gears, a gear channel, a clamping block and fixed pulleys, the surfaces of the main radial gate and the arc access door are cambered surfaces, the back faces of the main radial gate and the arc access door are planes, and an air sac is arranged in the arc access door and is controlled by the air switch. The automatic switch has the advantages of simple structure, low construction cost, safety, firmness and the like.

Description

technical field [0001] The invention relates to the technical field of water conservancy equipment, and more specifically relates to an automatic switch for arc gates suitable for culverts. Background technique [0002] At present, the gates of hydropower stations, such as the planar gates used by the Tuoxi Power Station in central Hunan, have high water head diversion, and the power generation distance is too far, which leads to loss of pressure; Drain the sediment deposited at the bottom. In addition, Ertan Hydropower Station, a major national power station, adopts a culvert type, large flow, and large orifice, and uses a cylindrical valve to divert water to generate electricity without automatic switching. This structure is complex and difficult to maintain. Contents of the invention [0003] The purpose of the present invention is to solve the deficiencies of the prior art, and provide a simple structure, energy saving, flexible opening and closing, safe and firm auto...

AI Technical Summary

Problems solved by technology

[0002] At present, the gates of hydropower stations, such as the planar gates used by the Tuoxi Power Station in central Hunan, have high head water diversion, and the power generation distance is too far, which leads to loss of pressure; Excretion of sediment deposited at the bottom

In addition, Ertan Hydropower Station, a major national power station, adopts cylindrical valves for non-automatic switch water diversion and power generation in culvert type, large flow, and large orifice. This structure is complex and difficult to repair and maintain.
