Strong tidal bore area one-way ecological fishway system based on Tesla valve principle
The invention discloses a strong tidal bore area one-way ecological fishway system based on a Tesla valve principle, which consists of a Tesla valve damp-resistant energy dissipation section, a multi-stage detachable ecological sand basin and a fish resting and monitoring pool which are closely connected in a linear structure. Most of tidal bore energy is eliminated through the Tesla valve tidal blocking and energy dissipation section, flowing water of the outer river is rectified into still water, the effect of one-way circulation from the inland river to the outer river is achieved, and fish migration is guided; sediment in the tidewater is settled through a multi-stage detachable ecological desilting basin, and'still water 'is changed into'purified water'; and finally, the fish rest and monitoring pool provides a rest space for the fishes and monitors the fishes. Through the ingenious design, the influence of tide level change, silt and tidal bore on the fishway is reduced, the fish migration time is shortened, the fish migration number is increased, and the ecological environment of the coastal area is improved.
本发明公开了一种基于特斯拉阀原理的强涌潮区单向生态鱼道系统，由特斯拉阀阻潮消能段、多级可拆卸生态沉沙池、鱼类休息兼监测池组成，呈“一”字形结构紧密相连。外江潮水经过特斯拉阀阻潮消能段消除大部分涌潮能量，将外江“动水”整流为“静水”，起到内河向外江单向流通作用，并引导鱼类洄游；再经过多级可拆卸生态沉沙池沉淀潮水中的泥沙，将“静水”变为“净水”；最后经过鱼类休息兼监测池为鱼类提供休息空间并进行监测。该发明通过巧妙的设计减小了潮位变化、泥沙、涌潮对鱼道的影响，提高了鱼类洄游时间及数量，改善了滨海区的生态环境。
