Bottom-layer fish descending dam passing efficiency improving device
The invention provides a bottom-layer fish descending dam-crossing efficiency improving device. The bottom-layer fish descending dam-crossing efficiency improving device comprises a river-crossing bridge. The river-crossing bridge is provided with a liftable fish collecting vehicle along piers, and fish luring equipment is arranged in the fish collecting vehicle. The river-crossing bridge is positioned at a position which is more than 100m away from the upstream of the dam. By arranging the fish blocking, fish collecting and lifting transferring system with the fish blocking net formed by thebottom layer macromolecular structure as the basic structure, upstream bottom layer incoming water is blocked, bottom layer inhabiting characteristic fishes with the downstream migration requirement are collected and transferred in a targeted mode to pass through a dam, the fish blocking net is folded after the downstream peak of the fishes, and silt is prevented. Potential safety hazards to operation of water conservancy and hydropower engineering are avoided structurally, the real-time control efficiency of fish gathering and transferring is improved by applying sonar in operation, and the device and method are particularly suitable for descending dam passing of bottom habitual fishes and help to improve safe, reliable, scientific, flexible and convenient descending dam passing of the bottom fishes.
本发明提供了一种底层鱼类下行过坝效率提升装置，包括跨河大桥；所述跨河大桥沿桥墩有可升降的集鱼车，集鱼车内装有诱鱼设备；所述跨河大桥位置位于相对于大坝的上游100m以上。本发明通过设置以底层高分子结构塑造的拦鱼网为基本结构的拦鱼、集鱼、提升转运系统，拦截上游底层来水，并针对性收集、转运具有下行洄游需求的底层栖息特性鱼类过坝，鱼类下行高峰过后收起拦鱼网，预防淤沙；在结构上不对水利水电工程运行产生安全隐患，在操作上运用声呐提高集鱼转运实时控制效率，特别适用于底层栖息习性鱼类下行过坝，是帮助提升底层鱼类安全可靠科学灵活便捷地下行过坝的装置及方法。
