Flat pressure adjusting structure for rapid emptying of high dam reservoir
The invention discloses a high dam reservoir rapid emptying flat pressure adjusting structure which comprises n water retaining gate wells, n emptying gate chambers and n adjusting pools, the water retaining gate wells and the emptying gate chambers are arranged on a tunnel, the tunnel is communicated with a reservoir, the arrangement sequence of the water retaining gate wells and the emptying gate chambers is the same as the flow direction of water flow in the tunnel, and the number of the water retaining gate wells and the number of the adjusting pools are both n, along the arrangement sequence of the water retaining gate wells on the tunnel, the ith water retaining gate well is communicated with the ith regulating reservoir through a water replenishing pipe, the ith regulating reservoir is communicated with the (i + 1) th regulating reservoir through an interstage overflow gallery, and the setting elevation of the ith regulating reservoir is greater than that of the (i + 1) th regulating reservoir; the last regulating reservoir is communicated with the downstream tunnel of the emptying lock chamber through a last-stage overflow gallery, and n and i are positive integers. By the adoption of the technical scheme, it is guaranteed that the water pressure in the gate shaft rapidly returns to be stable under the gate water leakage working condition, the valve operation frequency is reduced, and the stable gate water retaining overhaul operation working condition is achieved.
本发明公开了一种高坝水库快速放空的平压调节结构，包括挡水闸井、排空闸室和调节池，挡水闸井、排空闸室设置于隧洞上，隧洞与水库连通，并且挡水闸井、排空闸室的排列顺序与隧洞内的水流流向相同，挡水闸井、调节池的数量均为n个，其中，沿着挡水闸井在隧洞上的排列顺序，第i个挡水闸井与第i个调节池通过补水管连通，第i个调节池与第i+1个调节池通过级间溢水廊道连通，第i个调节池的设置高程大于第i+1个调节池的设置高程，最后一个调节池与排空闸室的下游隧洞通过末级溢水廊道连通，n、i均为正整数。采用本发明的技术方案，保证了闸门漏水工况下闸门井内的水压快速回归稳定，降低了阀门操作频次，实现了闸门挡水检修运行工况的稳定。
