Method for transforming vertical seam type fishway into movable partition plate type fishway
The invention discloses a method for transforming a vertical seam type fishway into a movable partition plate type fishway. The method comprises the steps that a, a fish inlet extends downstream; b) rebuilding a fish outlet into a transverse opening gate; c) energy dissipation baffles capable of being automatically controlled are additionally arranged between the pond chambers; when the defect of the original fishway is caused by the change of the upstream and downstream water levels, two reconstructions of a) extending the fish inlet to the downstream and b) reconstructing the fish outlet into a transverse opening gate are required to be carried out; when the defect of the original fishway is that a new low-swimming-speed fish passing type appears, improvement is carried out by adopting a method of adding an automatically-controlled energy dissipation baffle between pond chambers c); when an original fishway has the two problems at the same time, the method a), the method b) and the method c) are adopted for improvement at the same time. The method has the beneficial effects that the method for transforming the vertical seam type fishway is provided; a modification design method and a new body form of a fishway outlet; a modification method of a fishway entrance; the method and the body form play an important role in improving the fish passing efficiency.
本发明一种竖缝式鱼道改造为动隔板式鱼道的改造方法，包括：a)进鱼口向下游延伸；b)出鱼口改建为横向开启闸门；c)池室间增加可自动控制的消能挡板；当原鱼道的缺陷是由于上下游水位发生变化造成的，则需要进行a)进鱼口向下游延伸，b)出鱼口改建为横向开启闸门两项改造；当原鱼道的缺陷是由于出现新的低泳速过鱼种类时，采用c)池室间增加自动控制的消能挡板方法进行改进；当原鱼道同时出现以上两种问题时，同时采用a)，b)和c)方法进行改进。本发明的有益效果在于：本发明提出了竖缝式鱼道改造的方法；鱼道出口的改造设计方法和新的体型；鱼道入口的改造方法；以上方法和体型对鱼类通过效率提高具有重要作用。
