Anti-escape prevention device for upstream dam passing of migratory fishes in a hydropower station
The invention provides an anti-escape prevention device for upstream dam passing of migratory fishes in a hydropower station. A migration channel well is arranged on one side close to the downstream,of a reservoir dam, the migration channel well communicates with a downstream water area, a vertical shaft is arranged on one side close to the upstream, of the migration channel well, and the upper end of the vertical shaft is connected with a water outlet of the dam; a plurality of anti-escape cages are arranged in a swimming channel well, two parallel first horizontal frames are arranged on theupper sides and the lower sides of the anti-escape cages, the two first horizontal frames are fixedly connected through a supporting vertical frame, a blocking net fixed between the two first horizontal frames is arranged at the parts close to the upstream, of the anti-escape cages, and an opening with the adjustable width is reserved in the middle of the blocking net; and a trumpet-shaped anti-escape net cover is arranged in each first horizontal frame, and an opening in the front end of each anti-escape net cover is connected with an opening of the blocking net. The anti-escape cages are placed in the migration channel well, fishes are driven under migration habits to flow upwards and penetrate through the anti-escape cages to enter the vertical shaft, and the fishes can be prevented from swimming back through horn mouth design that the front parts of the anti-escape cages are narrow and the rear parts of the anti-escape cages are wide.
本发明提供了一种用于水电站洄游鱼类上行过坝的防逃装置，在水库堤坝靠近下游的一侧设置有洄游通道井，洄游通道井与下游水域相通，在洄游通道井靠近上游的一侧设置有竖井，竖井上端与堤坝的排水口相连；在游通道井设有若干防逃笼，防逃笼的上下两侧设置有两个平行的第一水平框架，两个第一水平框架之间通过支撑竖架固定连接，防逃笼靠近上游设置有固定在两个第一水平框架之间的拦网，拦网中间预留有宽度可调的开口；在第一水平框架内设置有喇叭状的防逃网罩，防逃网罩的前端开口与拦网的开口相连。将本发明防逃笼放置在洄游通道井中，鱼类在洄游习性驱使下逆流而上，穿过防逃笼进入到竖井中，防逃笼前窄后宽的喇叭口设计可以避免鱼类游回去。
