摘要
针对山区低闸引水式电站汛期污物难以清除的难题,设计了一种多层次清污系统。该系统由清污闸、拦沙坎、冲沙闸以及进水口拦污栅闸共同组成,清污闸快速清理大部分的漂浮物,拦沙坎拦截,冲沙闸清理下沉式污物,进水口拦污栅闸清除剩余污物。以龙洞水电站为例,阐述了该系统在实际工程中的应用。实践证明,该系统能够拦截并快速清理入库污物,有效解决了电站汛期的拦污及清污问题。
In order to solve the problem that it is difficult to remove the trashes at low sluice diversion hydropower station in mountainous area in flood season,a multi-level cleaning system is designed.The system is composed of a cleaning sluice,a sand trap,a sand sluicing gate and a trash rack gate at the water inlet.The cleaning sluice quickly cleans most of the floating objects,the sand trap intercepts,the sand sluicing gate cleans up the sinking trash,and the water inlet trash rack gate removes the remaining trash.Taking Longdong Hydropower Station as an example,the application of the system in practical engineering is described.The practice has proved that the system can intercept and quickly clean up the trashes in the reservoir,and effectively solve the problems of trash interception and cleaning in flood season.
