在水电站的进水口设置拦污栅,是改善进水口闸门工作条件,保证水轮机正常运行的重要设施。消除拦污栅的堵塞,进行清污,对漂浮物多,过栅流速大的低闸引水式电站尤为重要。本文以渔子溪一级水电站为例,介绍了该电站进水口增建清污闸和安装齿耙回转式清污机的设计与运行情况及其较果。 Setting up the trash rack at the inlet of the hydropower station is an important facility for improving the working conditions of the sluice gate and ensuring the normal operation of the turbine. Elimination of trash rack clogging, cleaning, the floating objects and more gate flow rate of low gate water diversion plant is particularly important. Taking Yuzixi - Ⅰ Hydropower Station as an example, this paper introduces the design and operation conditions of the new intake of the hydropower station and the installation of a rotary tainter with tooth harrow and its consequences.
