Multi-vertical-seam fishway with V-shaped baffles and short baffles
The invention belongs to the field of fish passing facilities, and relates to a multi-vertical-seam fishway with V-shaped baffles and short baffles, which comprises a bottom plate, side wall surfaces, side long baffles, the V-shaped baffles and the side short baffles. By reasonably arranging the V-shaped baffles and the short baffles, water flow is divided and converged after entering the fishway, so that the water flow is fully mixed, the energy of the water flow is effectively dispersed, and the flow velocity, turbulent kinetic energy and the like in the pond chamber are reduced. The two symmetrically-distributed vertical seam channels are arranged in the pond chamber, so that the fishway can adapt to changes of different water levels, the migration requirements of different fishes are met, and the use efficiency of the fishway is improved. According to the invention, smooth migration of fishes with weak swimming ability is facilitated, effective operation under low flow can be ensured, and the method has significant economic benefits for areas with water resource shortage or high power generation demand.
本发明属于过鱼设施领域，涉及一种带有V形挡板和短挡板的多竖缝鱼道，包括底板、侧壁面、侧面长挡板、V型挡板和侧面短挡板。本发明通过合理布局V形挡板和短挡板，使得水流进入鱼道后发生水流分流和汇聚，使得水流充分混掺，有效地分散了水流能量，降低了池室内流速和湍动能等。池室内提供两条对称分布的竖缝通道，能够适应不同水位的变化，满足不同鱼类的迁徙需求，提高鱼道的使用效率。本发明不仅有利于游泳能力较弱的鱼类顺利洄游，还能够保证在低流量下有效运行，对于水资源紧缺或发电需求高的地区具有显著的经济效益。
