Flow adjusting tank for controlling fishway water depth and fishway
The invention provides a flow adjusting tank for controlling fishway water depth and a fishway. An outlet and an inlet of the fishway are respectively connected with an upstream reservoir and a downstream river channel; the adjusting tank comprises a bottom plate and a side wall; the side wall is provided with a adjusting tank inlet and a adjusting tank outlet, the adjusting tank inlet is connected with an inlet-section fishway body, and the adjusting tank outlet is connected with an outlet-section fishway body; an overflow weir is arranged on the side wall, a step energy dissipation structureis arranged on the outer side of the overflow weir, and the overflow weir enables redundant water in the adjusting tank to overflow out of the tank in a self-overflow mode; a step is arranged at an inlet of the adjusting tank, and the top of the step is smoothly connected with the inlet-section fishway body and is higher than the bottom elevation of the adjusting tank; and the adjusting tank is configured to have a certain dead water level, the top of the step is lower than the top of the overflow weir, and a certain height difference is formed between the top of the step and the top of the overflow weir. According to the flow adjusting tank and the fishway, part of water in the fishway freely overflows through the overflow weir, so that the water depth in the fishway is controlled, the flow speed of water flow in the fishway is kept stable, the fish migration requirement is met, and the fish passing effect is improved.
本发明提供了一种控制鱼道水深的流量调节池及鱼道，所述鱼道的出口、进口分别与上游水库和下游河道相连，调节池包括底板和边墙，边墙上开设有调节池进口和调节池出口，调节池进口与进口段鱼道相连，调节池出口与出口段鱼道相连相连，所述边墙上还设有溢流堰，溢流堰外侧设置台阶消能结构，溢流堰采用自溢流的方式将调节池内多余的水溢出池外，所述调节池进口处设置台阶，台阶顶部与进口段鱼道平顺连接并高于调节池底高程，使调节池被配置为具有一定的死水位，台阶顶部低于溢流堰顶部，且与溢流堰顶部形成一定的高度差；本发明将鱼道内部分水量通过溢流堰自由溢出，控制鱼道内水深，维持鱼道内水流流速稳定，达到鱼类洄游要求，提升过鱼效果。
