Coupling type hydropower station desilting and desilting system
The coupling type hydropower station desilting and desilting system comprises water diversion pipelines connected to the front portions of flood discharge holes, the multiple flood discharge holes are arranged in the height direction of a retaining dam, the water diversion pipelines are connected with the different flood discharge holes through lifting units, and gates are arranged in the flood discharge holes. When the gate matched with the water level is opened, the gates located below the opened gate are all kept open. The water diversion pipeline is clamped with the flood discharge holes with different heights according to the height of the water level in the reservoir, when the water level is at any height, water can be drained normally, water flow impacts the pipe wall of the water diversion pipeline at different angles according to different water pressures during water drainage, silt deposited at all positions is scoured, the silt is prevented from remaining in the water diversion pipeline, and the service life of the water diversion pipeline is prolonged. The water discharge is influenced; the impacted point can be further changed by controlling the opening size of the gate, and silt on the inner wall of the water diversion pipeline is effectively cleaned.
本发明提出一种耦合式水电站清淤排沙系统，包括连接于泄洪洞口前方的引水管道，所述泄洪洞口沿拦水坝高度方向设置有若干个，所述引水管道通过升降单元与不同的泄洪洞口连接，所述泄洪洞口中设置有闸门，当与水位匹配的闸门开启时，位于开启闸门下方的闸门均保持开启。引水管道根据水库内水位的高低与高度不同的泄洪洞口卡接，当水位位于任何高度时，都可正常进行排水，排水的同时根据水压的不同，水流对引水管道的管壁进行不同角度的冲击，将各处淤积的泥沙进行冲刷，防止残留在引水管道中，影响排水量；通过控制闸门的开口大小可进一步改变被冲击点，有效对引水管道内壁的泥沙进行清理。
