Water diversion system for lower-level power station of cascade hydropower station
The invention discloses a water diversion system, particularly discloses a water diversion system for a lower-level power station of a cascade hydropower station, and belongs to the technical field of design and construction of water conservancy and hydropower engineering buildings. The water diversion system for the lower-level power station of the cascade hydropower station can effectively utilize the natural flow of a riverway interval between an upstream cascade dam site and a downstream cascade dam site to increase the generating capacity and can effectively reduce the scale of a downstream sand basin. The water diversion system comprises a tail water output structure of an upper-level power station, and further comprises a lower-level power station water inlet, a lower-level power station water diversion tunnel and a water supplementing structure; the water supplementing structure is arranged on a downstream riverway; and water flow output by the tail water output structure of the upper-level power station and water flow output by the water supplementing structure are input into the lower-level power station water diversion tunnel through the lower-level power station water inlet.
本发明公开了一种引水系统，尤其是公开了一种用于梯级水电站下级电站的引水系统，属于水利水电工程建筑物设计建造技术领域。提供一种既能够有效利用上、下游梯级坝址之间河道区间的天然流量来增加发电量，又能有效减小下游沉沙池规模的用于梯级水电站下级电站的引水系统。所述的引水系统包括上一级电站的尾水输出结构，所述的引水系统还包括下级电站进水口、下级电站引水隧洞和补水结构，所述的补水结构布置在下游河道上，上一级电站的尾水输出结构输出的水流和补水结构输出的水流均通过所述的下级电站进水口输入所述的下级电站引水隧洞中。
