Fishway inlet pulse water flow water replenishing method and system
The invention relates to a fishway inlet pulse water flow water supplementing method and system, an unpowered pulse water flow device is adopted at a fishway inlet, and periodic pulse water flow can be generated, so that fishes in a larger downstream area can sense the change of a water flow field, and then make an upstream reaction. The pulse water flow has long intermittent time, the fishway inlet flow field gradually recovers to the original shape, the boundary of the fish induction area gradually retreats, fish tracking and migration are facilitated, fish arrives at the fishway inlet to gather, and upstream tracing is achieved. By optimizing the hydraulic design of the pulse water flow device and assisting in mathematical model analysis and verification, a set of pulse water flow water supplementing system which not only saves water and energy consumption but also can improve the fish luring effect is formed.
本发明涉及一种鱼道进口脉冲水流补水方法及系统，通过在鱼道进口采用一种无动力脉冲水流装置，能够产生周期性的脉冲水流，使得下游更大区域内的鱼类能够感应到水体流场变化，进而做出上溯反应。脉冲水流具有较长的间歇时间，鱼道进口流场逐渐恢复原状，鱼类感应区边界逐渐回退，便于鱼类追踪、洄游，到达鱼道进口聚集，实现上溯。通过优化脉冲水流装置的水力设计，并辅以数学模型分析验证，形成一套既节省水量与能耗，又能提升诱鱼效果的脉冲水流补水系统。
