Energy dissipation structure of diversion aeration vertical shaft
The energy dissipation structure comprises a diversion canal, a volute chamber, a vertical shaft and a water outlet canal, the volute chamber is arranged above the vertical shaft, a water inlet of the volute chamber is connected with the diversion canal, a diversion ridge is arranged in the diversion canal, and an aerator ridge, a stilling well and the water outlet canal are arranged at the lower end of the vertical shaft. Ventilation holes are further formed in the aerator, each ventilation hole is connected with a ventilation pipe, and the ventilation pipes are selectively buried in the inner side of the vertical shaft. The structure is simple, construction is convenient, volute chamber inlet water flow is spirally discharged along the wall face of the vertical shaft under the flow guiding effect of the flow guiding ridge, the efficiency rate of the vertical shaft is improved, spiral water flow forms aerated water flow behind the ridge under the aeration effect of the aeration ridge at the lower end of the vertical shaft, the aeration and cavitation reduction effects can be achieved, the wall face is protected against cavitation damage, and the service life of the vertical shaft is prolonged. And safe operation of the vertical shaft under any working condition is ensured.
本发明公开了一种导流掺气竖井消能结构，包括引水渠，涡室，竖井以及出水渠，在所述竖井上方设置有涡室，并在涡室的进水口连接引水渠，将导流坎设置在引水渠内，而竖井下端则设置有掺气坎，消力井以及出水渠，在掺气坎上还设置有通气孔，每个通气孔都连接有通气管，而通气管选择埋设在竖井内侧。本发明结构简单，施工方便，涡室进口水流在导流坎导流作用下，沿竖井壁面螺旋下泄，竖井效能率得到提高，螺旋水流在竖井下端掺气坎的掺气作用下，在坎后形成掺气水流，能够起到掺气减蚀的效果，保护壁面免遭空蚀破坏，保证竖井能够在任何工况下安全运行。
