[0002] Mountain river channels have steep longitudinal slopes, fast water flow rates, and rich water energy. However, mountain river diversion projects often have problems such as long water diversion distances, water energy losses, and inability to completely divert water by gravity. Even if pumping stations are added during the water supply process, long-term operation will increase additional project costs. Therefore, there is an urgent need for a river diversion system that can improve water energy utilization, realize multi-level utilization of water energy, and improve water supply efficiency.
