Escape-proof device suitable for dam fish gathering and transporting system
The invention provides an escape-proof device suitable for a dam fish gathering and transporting system. A migration channel well is arranged on the side, close to the downstream, of a reservoir dam and communicates with a downstream water area; a vertical well is arranged on the side, close to the upstream, of the migration channel well; the upper end of the vertical well is connected with a water outlet of the dam; a plurality of escape-proof cages are arranged in the migration channel well; two parallel first horizontal frames are arranged on the upper side and the lower side of each escape-proof cage; every two corresponding first horizontal frames are fixedly connected through a supporting vertical frame; a blocking net fixed between every two corresponding first horizontal frames is arranged on the side, close to the upstream, of each escape-proof cage; an opening with the adjustable width is reserved in the middle of each blocking net; a horn-shaped escape-proof net cover is arranged in each first horizontal frame; and an opening in the front end of each escape-proof net cover is connected with the opening of the corresponding blocking net. The escape-proof cages are placed in the migration channel well, fishes are driven by the migration habit to flow upwards in the reverse direction and penetrate the escape-proof cages to enter the vertical well, and the fishes can be prevented from swimming back through the design of horn openings with the narrow front portions and the wide rear portions of the escape-proof cages.
本发明提供了一种适用于水坝集运鱼系统的防逃装置，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。
