Ecological fishway with turbulent flow assembly
The invention discloses an ecological fishway with turbulent flow assemblies, and belongs to the technical field of fishways. Comprising a plurality of fishway groove frames arranged in sequence, a gate is fixedly installed at the front end of the fishway groove frame located at the tail end, the two ends of one side of each fishway groove frame communicate with rest groove frames, the multiple fishway groove frames are arranged at an inclined angle, and a lifting mechanism used for lifting migratory fish schools is fixedly installed between every two adjacent fishway groove frames. According to the device, small vortexes of water flow can extend the retention time of fluid in the rear side area of the cross-shaped disturbance frame, so that impurity particles in the fluid can be adhered to the surface of the expansion air bag under the action of the vortexes, and planktons in the water flow can be adhered and reproduced on the surface of the expansion air bag; migratory fish schools can conveniently eat when staying on the surfaces of the expansion air bags, planktons adhering to the surfaces of the expansion air bags can be removed by inflating and deflating the adjusting pipes, the situation that impurities are accumulated to block the water flow passing ability between the turbulent flow frames on the two sides is avoided, and the use requirement is met.
本发明公开了一种具有扰流组件的生态鱼道，属于鱼道技术领域。包括多个顺序排列的鱼道槽框，且位于末端的鱼道槽框前端固定安装有闸门，所述鱼道槽框一侧两端均连通有休息槽框，且多个鱼道槽框呈倾斜角度排布，且相邻的两个鱼道槽框相对之间固定安装有用于提升洄游鱼群的抬升机构。本发明中，水流的小型涡流能够延展流体在十字形扰动架后侧区域的停留时间，使得流体中的杂质颗粒能够通过涡流的作用粘附在膨胀气囊表面，并且水流中的浮游生物还能够粘附繁殖在膨胀气囊表面，方便洄游鱼群在膨胀气囊表面停留时进行采食，膨胀气囊表面能够通过调节管的充放气去除表面粘附的浮游生物，避免杂质积蓄堵塞两侧扰流架之间的水流通过性，满足使用需要。
