深圳抽水蓄能电站上水库进/出水口拦污栅设计

摘要

抽水蓄能电站的水道布置较为复杂，理想的进水口布置形式常受到输水道条件、扩散段体型等诸多因素的影响和限制。深圳抽水蓄能电站上库进/出水口的拦污栅的布置方式为将栅槽一侧轨道做成斜面，对应的拦污栅支承滑块与之保持对应的斜率，确保拦污栅放置入栅槽后栅叶上的支承滑块与栅槽的轨道面之间没有间隙的半固定式布置方式。实践证明，该布置方式可以有效限制栏污栅在栅槽中的振动，并且可以确保拦污栅的检修条件。%Channel arrangement of pumped-storage power station is relatively complex, so the ideal water inlet arrangement type often is limited to two conditions. Design of diffusion section shape also has many limitations. The track of the trash rack in Shenz-hen pumped storage power station is designed as slopes, and also kept the supporting slider of the trash rack to fit with the track to make sure the trash rack was semi-fixed in the channels. Practice has proved that this placement take effective at limiting the vi-bration of trash rack, and also kept the maintenance condition of the trash rack.
