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.

Embodiment Construction
[0018] Such as figure 1 , figure 2 As shown, the present invention is suitable for culvert-type arc gate automatic switch, including the control mechanism on the dam, the arc inspection door 3 near the water source in front of the dam 1, and the arc main gate 2 on the dam 1; the control mechanism includes Air switch 4, contraction steel cable 5, gear, gearway 6, block and fixed pulley 7. The surfaces of the arc-shaped main gate 2 and the arc-shaped maintenance door 3 are arc surfaces respectively, and the back surfaces are planes. An air bag 8 is arranged in the arc inspection door 3, and is controlled by an air switch 4. The outer ends of the arc-shaped main gate 2 and the arc-shaped inspection door 3, and the other side of the dam when the gate is closed, are provided with fixed pulleys 7, and the shrinkage steel cables 4 are respectively connected to the outer ends of the arc-shaped main gate 2 and the arc-shaped inspection door 3. end, and connect and wind each fixed p...

The invention discloses an automatic switch for a culvert type arc gate, which includes a control mechanism on a dam, and is characterized in that it also includes an arc inspection gate close to the water source in front of the dam and an arc main gate of the dam; The control mechanism includes an air switch, a contraction cable, a gear, a gear track, a block and a fixed pulley. The surfaces of the arc-shaped main gate and the arc-shaped maintenance door are respectively arc-shaped, and the back is plane. An air bag is arranged inside the arc-shaped inspection door, which is controlled by an air switch. The invention has the advantages of simple structure, low construction cost, safety and firmness.
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...
