High-fall water conservancy dam flood discharge opposite flushing structure
The invention relates to the field of water conservancy projects, in particular to a high-fall water conservancy dam flood discharge opposite flushing structure. According to the flood discharge hedging structure of the high-fall water conservancy dam, through cooperation of the dam body, the flood discharge gate, the downward sliding part, the arc-shaped upward raising groove, the hedging opening, the water flow channel, the overflow inlet and the like, first water flow flows out of the arc-shaped upward raising groove, the emergence angle of the first water flow is c, second water flow flows out of the hedging opening, the emergence angle of the second water flow is d, and d is larger than c; one part of water flow is discharged from the outer side of the dam body along the flood discharge gate, the lower sliding part and the arc-shaped upward-raising groove, and upward-raising first water flow is formed in the position of the upward-raising groove; the other part of water flow enters from the overflow inlet, second water flow flows out from the opposite flushing opening along the water flow channel in the dam body, the emergent angle d of the second water flow is larger than the emergent angle c of the first water flow, and the second water flow collides with the first water flow upwards, so that potential energy is greatly consumed, and the impact of the water flow on the foundation of the dam body is greatly reduced; potential safety hazards are reduced, and the service life is prolonged.
本发明涉及水利工程领域，具体涉及一种高落差水利大坝泄洪对冲结构。本发明的高落差水利大坝泄洪对冲结构，通过大坝本体、泄洪闸、下滑部、弧形上扬槽、对冲口、水流通道以及溢流进口等的配合，弧形上扬槽流出第一水流，其出射角度为c，对冲口流出第二水流，其出射角度为d，有d＞c，一部分水流从大坝本体外侧沿着泄洪闸、下滑部、弧形上扬槽排泄，在上扬槽的位置形成上扬的第一水流；另一部分水流从溢流进口进入，沿着大坝本体内部的水流通道从对冲口流出第二水流，由于第二水流的出射角度d大于第一水流的出射角度c，第二水流向上与第一水流对冲碰撞，大大消耗了势能，大大减小水流对大坝本体根基的冲击，减小了安全隐患，延长使用寿命。
