The multi-layer fishway is arranged on the downstream side of a dam and used for allowing fishes on the downstream side to migrate towards the upstream side of the dam, at least one fish outlet is formed in the side, close to the dam, of the multi-layer fishway, each fish outlet is provided with a fishway water level adjusting mechanism, and each fishway water level adjusting mechanism comprises an adjusting gate and a driving mechanism; a rotating shaft is arranged at the bottom of the adjusting gate, and the driving mechanism drives the adjusting gate to rotate around the rotating shaft so that the adjusting gate can be switched between the opening position and the closing position. According to the multi-layer fishway, the rotary type three-dimensional multi-layer fishway is adopted, the fish outlets are formed in each layer of the multi-layer fishway close to the dam, and when the water level height of the upstream side river channel changes, the adjusting gates of the fish outlets with different heights can be opened, so that the water flow and the water flow speed of upstream side water flowing into the fishway channel are suitable for migration of downstream side fishes.
本发明公开了一种多层鱼道，多层鱼道设置于水坝下游侧，用于下游侧鱼类向水坝上游侧洄游，多层鱼道在靠近水坝一侧设置至少一个出鱼口，每个出鱼口设置一个鱼道水位调节机构，鱼道水位调节机构包括调节闸门和驱动机构，调节闸门的底部设置有转轴，驱动机构驱动调节闸门绕转轴转动，使得调节闸门在打开位置和关闭位置间切换。本发明的多层鱼道采用回旋式立体多层鱼道，通过紧靠水坝在多层鱼道的每层均设置出鱼口，在上游侧河道水位高度变化时，可打开不同高度的出鱼口的调节闸门，使得上游侧水流入鱼道通道中水流量和水流速适宜下游侧鱼类洄游。
