Hydraulic impact rotating cylinder fishway
The invention discloses a hydraulic impact rotating cylinder fishway, and particularly relates to the technical field of river blocking building fish passing. The hydraulic impact rotating cylinder fishway comprises a gate foundation groove fixed to a riverbed at the bottom of an inlet of the fishway, a flow guide assembly is arranged at the inlet side of the gate foundation groove, a row of waterflow adjusting mechanisms and partition plate assemblies are arranged in the middle of the gate base groove in the water flowing direction in an alternative manner and divide the fishway into a leftpart and a right part, namely a slow flow area and a rapid flow area, an adjusting partition plate is arranged at an inlet of the rapid flow area, and the water flow adjusting mechanisms comprise vertical shafts, rotating cylinders and blades. According to the hydraulic impact rotating cylinder fishway, the water flow structure is improved through the rotating cylinders, the local flow field is effectively adjusted, the hydraulic impact rotating cylinder fishway is suitable for running of target fishes, the flowing speed is reduced, so that the physical strength recovery of the fishes in the upstream process is facilitated, and the fish passing effect is improved; and the overall structure is simple, too much maintenance is not needed, and the hydraulic impact rotating cylinder fishway iseconomically suitable for various hydraulic engineering and suitable for high-water-head dams.
本发明公开了一种水力冲击旋转筒鱼道，具体涉及拦河建筑物过鱼技术领域，包括固定于鱼道进口底部河床上的闸基槽，所述闸基槽入口侧设有导流组件，所述闸基槽中间位置沿水流方向设有一排间隔交叉设置的水流调节机构和隔板组件，将鱼道分为缓流区和急流区左右两部分，所述急流区入口处设有调节隔板；水流调节机构包括立轴、旋转筒和叶片。本发明通过旋转筒改善了水流结构，有效调整了局部流场，适宜于目标鱼类洄游，流速减缓有利于鱼类上溯过程中恢复体力，提高了过鱼效果，并且整体结构简单，无需太多维护，经济适用于各种水工工程，适应于高水头大坝。
