Fish centralized transportation method and system for upstream dam crossing of migratory fishes in hydropower station
The invention provides a fish centralized transportation method and system for upstream dam crossing of migratory fishes in a hydropower station. Downstream migratory fishes upstream penetrate throughanti-escape cages to enter a vertical shaft; a fish collecting box with the vertical shaft sinking in the water is lifted away from the water surface, the fishes in the fish collecting box slide intoa water storage hopper at the bottom of the fish collecting box, and then the water storage hopper at the bottom of the fish collecting box is connected with a sliding chute on the dam; a gate valveis opened, the fishes in the water storage hopper flow into the sliding chute along with the water, the fishes flowing out of the sliding chute are conveyed into a temporary culture pond through grading grids, the small fish can fall into a first temporary culture area from gaps among the grid strips, and big fishes can slide into a second temporary culture area from the grading grids; and the fishes in each temporary culture area are transferred to an upstream water area. According to the fish centralized transportation method and system, the migratory fishes can go up and pass through the dam, the blocking effect of the dam on the upward movement of the migratory fishes is relieved, and the sustainable purpose of original ecology of the fishes is protected.
本发明提供了一种用于水电站洄游鱼类上行过坝的集运鱼方法及系统，下游的洄游鱼类逆流而上穿过防逃笼进入到竖井中；将竖井沉在水中的集鱼箱吊离水面，集鱼箱中的鱼溜到集鱼槽底部的存水斗中，随后将集鱼箱底部的存水斗与堤坝上的滑槽相连；打开闸阀，存水斗中的鱼随水流到滑槽中，滑槽流出的鱼经过分级格栅输送到暂养池中，小鱼从格栅条之间的间隙中掉落至第一暂养区，大鱼在分级格栅上滑落至第二暂养区；将各暂养区中的鱼转运至上游水域。本发明可以帮助洄游鱼类上行过坝，减缓了大坝对洄游鱼类上行的阻隔作用，保护了鱼类原生态的可持续目的。
