Embodiment Construction
[0016] The technical solution of the present invention is further described below in conjunction with the accompanying drawings, but the scope of protection is not limited to the description.
[0017] Such as figure 1 , figure 2 As shown, the present invention provides a kind of air replenishment device used in the sluice chamber system, which includes an air replenishment tunnel 1, and the sluice chamber system is arranged in the mountain body, and the sluice chamber system includes sluice chambers arranged opposite to each other, Between the two sluice chambers, there is a sluice gate that can movably intercept the water flow. The air supply tunnel 1 is arranged within the mountain body 3 arranged with the discharge sluice chamber system. One end of the air supply tunnel 1 is used as the air outlet 101 to communicate with the sluice chamber respectively. The other end of the air supply hole 1 is used as an air inlet 102 to communicate with the outside atmosphere.

The invention discloses an air supply device for use in a sluice chamber system. The device comprises an air supply hole; the sluice chamber system is arranged in a mountain body, and comprises sluicechambers which are arranged opposite to each other; the two sluice chambers are internally and separately provided with a gate capable of movably intercepting water flow; the air supply hole is formed in the mountain body; one end of the air supply hole is used as an air outlet and is separately communicated with the sluice chambers; the other end of the air supply hole is used as an air inlet and is communicated with the outside atmosphere. After the technical scheme is adopted, the air in the local atmospheric environment is introduced for supplying air for the sluice chamber system by forming the air supply hole in the mountain body, so that the sluice chamber system is effectively ventilated, and the safe operation of the sluice chamber system is guaranteed; furthermore, the air supply device provided by the invention is simple in construction, greatly reduces the investment cost and improves the economic benefit.
Description
technical field [0001] The invention belongs to the technical field of water conservancy and hydropower engineering, and in particular relates to an air replenishing device used in a sluice chamber system. Background technique [0002] With the emergence of high dams, higher requirements are put forward for the venting and operation of the project. At present, an ultra-deep water-retaining venting system has appeared, which can not only meet the existing metal structure manufacturing level, but also increase the venting depth. The Chinese invention patent with the publication number CN105220659B discloses an ultra-deep water retaining and venting system for a high dam reservoir and an operation method thereof. The technical solution is to share the total water head by setting multi-level gates, and fill water behind the gates at all levels to offset the water-retaining head, so that the water thrust of the gates at all levels is within the conventional design range. At the...
