Problems solved by technology

However, there are also two prominent problems with gas shield dams. One is that there are only two working conditions for the operation of the gas shield dam, the normal water-retaining state and the lodging discharge state, that is, the gas shield dam cannot achieve half-transportation; the second is that the gas shield dam The dam crest falls directly to the dam foundation after passing through the water. It looks like a waterfall and generates a lot of noise, which is likely to cause noise pollution to the surrounding environment. It will also block the river channel during work, making it impossible for migratory organisms to pass through, causing serious damage to the river ecology. severe impact

Embodiment 1

[0061] see figure 1 and figure 2 As shown, the dam includes an air compressor 10 and a dam 1 accommodated in the foundation pit 2;

[0062] The foundation pit 2 is located in the river channel 4, the gate dam 1 has a first water retaining plate 5 and a second water retaining plate 6, one end of the second water retaining plate 6 is hinged to the foundation pit 2, and the other One end is connected with the top of the first water retaining plate 5;

[0063] There is an air bag 3 in the dam 1, and the air bag 3 is connected to the air compressor 10;

[0064] When the air bag 3 is inflated, the first water retaining plate 5 and the second water retaining plate 6 protrude from the foundation pit 2 so that the first water retaining plate 5 has an uphill gradient and the second retaining plate The water plate 6 has a downhill slope;

[0065] And when the air bag 3 is deflated, the first water retaining plate 5 is folded in the foundation pit 2 , and the second water retaining p...

Abstract

The invention belongs to the technical field of barrages, and particularly relates to a movable barrage. The movable barrage comprises an air compressor and a gate dam contained in a foundation pit. The foundation pit is located in a river channel, the gate dam is provided with a first water baffle and a second water baffle, one end of the second water baffle is hinged to the foundation pit, and the other end of the second water baffle is connected with the top end of the first water baffle. An air bag is arranged in the gate dam and is connected with the air compressor; and when the air bag is inflated, the first water baffle and the second water baffle protrude out of the foundation pit so that the first water baffle can have an uphill gradient and the second water baffle can have a downhill gradient. When the air bag is deflated, the first water baffle is folded in the foundation pit, and the second water baffle is flush with the bottom surface of the river channel. According to the movable barrage, the structural strength is high, noise pollution generated during water passing can be effectively reduced, and the influence of the barrage on the ecological environment in the river channel is reduced.

Description

technical field [0001] The invention belongs to the technical field of barrages, in particular to a movable barrage. Background technique [0002] As the main water conservancy facilities, barrage dams, fixed or movable, will directly affect the ecological environment in and around the river. With the development of science and technology and the enhancement of people's awareness of ecological environment protection, the selection of retaining dams becomes more cautious. Except for the gravity concrete barrages used in large-scale reservoir power stations, fixed gravity barrages are generally no longer built in conventional river courses, and most of them use lifting gates, hydraulic gate dams, rubber dams, and air shield dams. The main feature of these dams is that they are movable, can be raised and lowered, and can block the river to store water during normal work. When the flood season comes, the gates can be opened to quickly discharge floods, solving the threat of flo...
