Fish collecting system and fish collecting method for hybrid hydropower station
The invention relates to the technical field of water conservancy and hydropower engineering, in particular to a fish collecting system and method of a hybrid hydropower station. A fish collecting system of a hybrid hydropower station is arranged at a tail water port of the hybrid hydropower station and comprises a fish collecting channel, the two ends of the fish collecting channel are provided with a fish collecting inlet and a water flow inlet respectively, an inlet gate is arranged at the fish collecting inlet, an outlet gate is arranged at the water flow inlet, and water flow comes from ecological flow or power generation tail water. A fish collecting pond is arranged in the fish collecting channel close to the outlet gate, and a movable fish driving grating is arranged between the inlet gate and the fish collecting pond; a sorting layer is arranged on the upper side of the fish collecting pond; the fish blocking weir is obliquely arranged, and a drainage area is defined by the fish blocking weir, the fish collecting side wall and the second outer wall. In order to solve the technical problem that an existing fish collecting system has defects, the ecological flow discharged by the mixed hydropower station is combined and utilized for fish collection, the operation cost is low, the fish collecting effect is good, the fish application range is wide, and operation is easy.
本发明涉及水利水电工程技术领域，具体涉及一种混合式水电站的集鱼系统及集鱼方法。一种混合式水电站的集鱼系统，布置于混合式水电站尾水口处，包括集鱼通道，集鱼通道的两端分别为集鱼进口和水流入口，集鱼进口处设有进口闸门，水流入口处设有出口闸门，水流来自生态流量或发电尾水，集鱼通道内靠近出口闸门处设有集鱼池，进口闸门与集鱼池之间设有活动的赶鱼格栅；集鱼池上侧设置有分拣层，还包括集鱼箱和提升机构；还包括倾斜设置的拦鱼堰，拦鱼堰、集鱼边墙和第二外墙围合构成泄流区域。针对现有集鱼系统存在缺陷的技术问题，本发明结合并利用了混合式水电站的下泄生态流量进行集鱼，运行成本低，集鱼效果好，适用鱼类范围广，且操作简单。
