Fish passing system utilizing longitudinal cofferdam for fish passing
The invention discloses a fish passing system utilizing a longitudinal cofferdam for fish passing, and belongs to the technical field of water conservancy and hydropower ecological protection. The system comprises a riverway and a floating type fishway, a longitudinal cofferdam is arranged in the riverway in the water flow direction and connected with a bank slope on one side of the riverway through a transverse cofferdam, the downstream section of the longitudinal cofferdam is bent in the direction away from the transverse cofferdam to form a bent arc section, and a fish trapping mechanism is arranged on the downstream side of the bent arc section. The floating type fishway is in sliding connection with the waterside of the longitudinal cofferdam, and the downstream end of the floating type fishway is connected with the downstream end of the fish trapping mechanism through the fish lifting mechanism. The floating fishway can be self-adaptively lifted according to the water level of the upstream reservoir area of the high dam, so that downstream fishes can be smoothly upstream migrated to the water level of the upstream reservoir area of the high dam, the fishes are prevented from being greatly impacted when entering the water body of the reservoir area, and fish protection is facilitated.
本发明公开了一种利用纵向围堰进行过鱼的过鱼系统，属于水利水电生态保护技术领域。该系统包括河道和漂浮式鱼道，所述河道内顺水流方向设有纵向围堰，所述纵向围堰通过横向围堰与河道一侧的岸坡连接，且纵向围堰的下游段向背离横向围堰的方向弯曲形成弯弧段，所述弯弧段的背水侧设有诱集鱼机构，所述漂浮式鱼道与纵向围堰的临水侧滑动连接，且漂浮式鱼道的下游端通过鱼类提升机构与诱集鱼机构的下游端相衔接。漂浮式鱼道能够根据高坝上游库区水位进行自适应升降，确保下游鱼类能够顺利上溯洄游到高坝上游库区水位中，并避免鱼类进入库区水体时受到较大的冲击，有利于鱼类保护。
