Non-constant flow water-saving type turning plate step type fishway and fish migration method
The invention discloses a non-constant flow water-saving turning plate step type fishway and a fish migration method, a plurality of turning plates are arranged in a fishway body along the length direction of the fishway body, and each turning plate transversely partitions the fishway body, so that a multi-stage migration pool enclosed by two adjacent turning plates is formed; the elevation of the upper end of each turning plate is gradually reduced along the water flow direction; all the turning plates can connect or disconnect the adjacent migration ponds. The first-level turning plate, the second-level turning plate, the third-level turning plate and the like are sequentially opened and closed according to the set rhythm until the turning plate at the uppermost end, fishes enter the migration pool at the upper level in the turning plate opening process, and dam turning is achieved through step-by-step migration. According to the fishway, the requirement for the swimming capacity of fishes is basically avoided, drop water formed in the opening process of the turning plates has the attraction effect on the fishes, fish migration is quite facilitated, and the water flow for achieving migration is smaller than that of an existing fishway.
本发明公开了一种非恒定流节水型翻板梯级式鱼道及鱼类洄游方法，在鱼道本体中沿鱼道本体长度方向设有若干翻板，每块翻板将鱼道本体横向隔断，从而形成由相邻两翻板围成的多级洄游池；每块翻板上端高程沿水流方向逐渐降低；所有翻板可将相邻洄游池连通或者断开。本发明按设定节奏依次打开关闭一级翻板、二级翻板、三级翻板……，直至最上端的翻板，鱼类在翻板打开过程中进入上一级洄游池，逐级洄游即实现翻坝。本发明对鱼类的游动能力基本无要求，翻板在开启过程中所形成的跌水对鱼类具有吸引作用，十分有利于鱼类洄游，而且实现洄游的水流量也小于现有鱼道。
