The invention provides a fish collecting station for river migratory fish, improves the fish collecting efficiency of river migratory fish, and solves the problem of high dam engineering migratory fish passing through dam in mountain and canyon area. The fish collecting station is composed of a guiding net wall, a fish collecting platform and a transportation channel, and the shrinkage opening at the upstream end of the net wall is connected with the fish collecting box of the fish collecting platform. The fish collecting platform is divided into fish collecting layer and fish unloading layer, and the fish collecting box is located below the water surface; the fish collecting box is divided into upper and lower parts, the upper part is the net clothing that can pass through the water, and the lower part is the substantial frame that can not pass through the water, so as to ensure that there is water at the bottom of the fish collecting box during the lifting and transferring process, so as to provide conditions for the normal survival of fish. A fish unloading layer is built above the water surface of the fish collecting platform. The lifting, landing, replacement and unloading of the fish collecting box are realized by the door opener installed above the fish unloading platform. The fish collecting box is unloaded and sorted in the fish unloading layer. The fish unloading platform is connected with the transportation channel to realize the transfer of the target fish through the dam.

一种河流洄游鱼类集鱼站
本专利技术涉及河流洄游鱼类集鱼站建设技术。
技术介绍
水电是清洁能源,具有可再生、无污染、运行费用低、便于进行电力调峰等诸多优点,近年来随着三峡、溪洛渡等大型水利水电工程建设,中国已成为世界水电第一大国,水电在国计民生中发挥着重要作用。由于河流水利水电工程等梯级建设,导致河流纵向连通受阻,上下游水体在地理空间上的连续受到阻隔,对洄游鱼类的生物过程连续造成较大影响。国内外常采用修筑洄游通道的方法以期降低工业设施建设对洄游鱼类造成的负面影响,从资料分析来看,国内外的鱼道并没有达到理想效果;另外大型水利水电工程通常上下游水位差越大,技术型鱼道对地理条件的要求越高,建设成本也越高。因此,国内外提出通过人工诱集和活体运输辅助鱼类实现溯河洄游,以满足水利水电不能建设技术型鱼道条件时的过鱼需求。人工诱集设施如集鱼箱、集鱼船等,国内已有相关报道,但是未见具体实施,效果如何尚不明了,另外,大型水利水电工程下游往往水流湍急(水流速度可达7m/s)、流态复杂、河岸和河底地形变化剧烈、乱石林立等原因,这些客观因素均给集鱼设施 ...
