Spiral stacked fishway outlet structure suitable for large water level amplitude
The invention provides a spiral stacking type fishway outlet structure suitable for a large water level amplitude. The spiral stacking type fishway outlet structure comprises a spiral stacking type fishway, a supporting foundation, a plurality of fishway outlets and an outlet gate. The supporting foundation is fixed to a side slope or a river bottom so as to support the spiral stacked fishway. The plurality of fishway outlets are positioned in the same direction of different layers of the outer wall of the spiral stacked fishway and correspond to different running water levels; the other direction of the same layer of the fishway outlet of the bottommost layer is a water flow outlet of the spiral stacked fishway, the elevation of the water flow outlet is lower than that of the spiral stacked fishway, and the water flow outlet is connected with the matched fishway; the multiple fishway outlets share the same outlet gate, the outlet gate is located on the outer sides of the multiple fishway outlets, the outlet gate can move in the height direction, and unified opening and closing control over the multiple fishway outlets is achieved. Linkage control over multiple gates is not needed, opening and closing control over multiple fishway outlets is achieved by controlling one gate, and the device is suitable for the upstream large-water-level variable-amplitude operation environment.
本发明提供了一种适用于大水位变幅的盘旋层叠式鱼道出口结构，包括盘旋层叠式鱼道、支撑基础、多个鱼道出口、出口闸门；所述支撑基础固定于边坡或河底以支撑盘旋层叠式鱼道；多个鱼道出口位于盘旋层叠式鱼道外壁不同层的同一方位，对应不同运行水位；最底层鱼道出口的同层另一方位为盘旋层叠式鱼道的水流出口，水流出口的高程低于盘旋层叠式鱼道的高程，水流出口与配套鱼道连接；多个鱼道出口共用同一个出口闸门，出口闸门位于多个鱼道出口的外侧，出口闸门能够在高度方向上进行移动，实现对多个鱼道出口进行统一启闭控制。本发明不需要联动控制多个闸门，通过控制一个闸门实现多个鱼道出口的启闭控制，适用于上游大水位变幅运行环境。
