Fish collecting well suitable for tail water of power station
The invention discloses a fish collecting well suitable for tail water of a power station. The fish collecting well is arranged on the downstream side of a tail water tunnel guide wall of the power station. A fish collecting pit and a fish collecting box arranged in the fish collecting pit are arranged in the fish collecting well, flow guide walls extending to the two sides of the tail water tunnel guide wall are arranged on the two sides of the fish collecting well, tail water channels which are communicated with the fish collecting box and can be opened and closed are formed between the flow guide walls and the tail water tunnel guide wall, and a plurality of energy dissipation piles are arranged between the fish collecting box and the tail water channels on the two sides; a plurality of fish inlets which are communicated with the fish collecting box and can be opened and closed are formed in the downstream side of the fish collecting well. The tail water of the power station is drained into the fish collecting well through the tail water channel, the drained tail water of the power station is subjected to energy dissipation through the energy dissipation piles, the flow speed and the flow state of the tail water of the power station are improved, a rapid flow area and a slow flow area are formed at different positions in the fish collecting well, and fishes are promoted to enter the fish collecting well; and the fishes can be conveniently collected and lifted through the fish collecting box in the fish collecting pit.
本发明公开了适用于电站尾水的集鱼井，集鱼井设置在电站的尾水洞导墙下游侧；集鱼井内部设有集鱼坑以及设置在集鱼坑内的集鱼箱，集鱼井的两侧设有延伸至尾水洞导墙两侧的导流墙，导流墙与尾水洞导墙之间形成与集鱼箱连通的且可开闭的尾水渠，集鱼箱与两侧的尾水渠之间设有多个消能桩；集鱼井的下游侧设有多个与集鱼箱连通且可开闭的进鱼口。本发明通过尾水渠将电站尾水引流至集鱼井中，并通过消能桩对所引流的电站尾水进行消能，对电站尾水的流速和流态进行改善，在集鱼井内部的不同位置处形成急流区和缓流区，促使鱼类进入集鱼井中，便于通过集鱼坑中的集鱼箱对鱼类进行收集提升。
