Fishway structure and use method thereof
The invention discloses a fishway structure and a using method thereof.The fishway structure comprises a dam lower section, a dam passing section and an on-dam reservoir inner section, the dam lower section, the dam passing section and the on-dam reservoir inner section are sequentially communicated and form a fishway, the dam lower section is provided with a plurality of fish inlets located at different water level elevations, and the outlet end of the on-dam reservoir inner section is connected with a fish lifting tower; the fish lifting tower is used for adjusting the water level change of the fish collecting pond in the fish lifting tower, so that the water level of the fish collecting pond is smoothly connected with the water level of the upstream reservoir, and fishes enter the upstream reservoir from the fish lifting tower. The fish inlets with different elevations are formed in the fishway inlet section to meet the fish luring condition, fishes can enter the fishway, the fishes climb and migrate to the bottom of a dam upstream reservoir through the spiral fishway, and the fish lifting tower is designed according to the principle of a ship lift. The water level in the fish lifting tower is controlled to be freely connected with any water level in the upstream reservoir, so that fishes can freely pass through the dam, and the purpose of protecting the breeding of the fishes in the river channel is achieved.
本发明公开了一种鱼道结构及其使用方法，该鱼道结构包括坝下段、过坝段和坝上库内段，坝下段、过坝段和坝上库内段依次连通并形成鱼道，坝下段设有若干位于不同水位高程的进鱼口，坝上库内段的出口端连接有升鱼塔，升鱼塔用于调节其内部的集鱼池水位变化，使集鱼池的水位与上游水库的水位平顺衔接，从而使鱼类从升鱼塔进入上游水库中。本发明通过在鱼道进口段设置不同高程的进鱼口满足诱鱼条件，使鱼类能够进入鱼道中，鱼类通过螺旋式鱼道进行爬坡洄游至大坝上游水库底部，利用升船机的原理设计的升鱼塔，通过控制升鱼塔内水位使其水位和上游水库内任意水位自由衔接，从而达到鱼类自由过坝进而保护河道鱼类繁殖的目的。
