Multi-channel fishway
The invention discloses a multi-channel type fishway, belongs to the technical field of fishways, and can solve the problems of change of upstream incoming flow of the fishway and adaptation to upstream tracing of multi-target fishes. A side wall and a bottom plate of the fishway form the whole fishway, and two arc-shaped long partition plates are arranged in the middle to divide the whole fishway into three channels. A main flow channel in the water flow direction is formed between the two arc-shaped long partition plates, when the flow in the fishway is large, the flow pressure of the channels on the two sides can be reduced, meanwhile, an upstream channel can be provided for fishes with the high swimming capacity, the U-shaped partition plates are arranged on the two sides of the main flow channel respectively, and a rest pool is formed in the middle of each U-shaped partition plate. A temporary rest place is provided for upstream fishes, and a main stream entering channel is formed between the two U-shaped partition plates. An arc-shaped channel simulating a natural river is arranged between the arc-shaped long partition plate and the side walls on the two sides and is a main upstream channel for fishes with weak swimming ability.
本发明公开一种多通道式鱼道，属于鱼道技术领域，能够解决鱼道上游来流量的变化及适应多目标鱼类上溯的问题。该鱼道的边墙和底板组成整个鱼道，中间设置两块弧形长隔板将整体鱼道分为了三个通道。两弧形长隔板之间为沿水流方向的主流通道，当鱼道内流量较大时，能减小两侧通道流量压力的同时也可以为游泳能力较强的鱼类提供上溯通道，主流通道两侧分别布置U形隔板，每个U形隔板中间为休息池，为上溯的鱼类提供短暂的休息场所，两U形隔板中间为进入主流的通道。弧形长隔板与两侧边墙之间为模仿自然河流的弧形通道，是游泳能力较弱的鱼类的主要上溯通道。
