Fish collecting system based on fish blocking weir
According to the fish collecting system based on the fish blocking weir, after a tail water channel is divided into a thin-walled weir water channel and a fish collecting water channel, on one hand, the thin-walled weir has a certain height, fishes are prevented from swimming into the thin-walled weir water channel from the thin-walled weir, and therefore the fishes only swim into a fish collecting box of the fish collecting water channel; on the other hand, the proper height of the thin-walled weir is designed, so that the flow speed of water flowing out of the fish collecting box is not larger than the swimming capacity of the fishes, and most fishes can swim in without obstacles. The simple structure is suitable for river development hydroelectric power generation with small runoff volume, the counterfeit investment is low, and a complex fish collecting and luring system does not need to be redesigned.
本发明公布了一种基于拦鱼堰的集鱼系统，尾水渠分为薄壁堰水渠和集鱼水渠后，一方面薄壁堰具有一定高度，阻止了鱼类从薄壁堰游入薄壁堰水渠，鱼类因此仅游入集鱼水渠的集鱼箱内；另一方面本发明通过设计合适的薄壁堰高度，使从集鱼箱流出的水流流速不大于鱼类游泳能力，使大部分鱼类都能无障碍游入。本发明的简单结构适合于径流量不大的河流开发水利发电，造假投入低，不用重新设计复杂的集鱼诱鱼系统。
