Water inlet and outlet trash rack of pumped storage power station and trash rack system thereof
The invention belongs to the field of industrial building structures, provides a water inlet and outlet trash rack of a pumped storage power station and a trash rack system of the water inlet and outlet trash rack, solves the problem of adverse influence of a sundry stacking effect caused by a single-layer trash rack on unobstructed water flow, and adopts the technical scheme that the trash rack comprises a plurality of stages of grilles and grille clamping grooves for fixing the grilles; the multi-stage grids are sequentially fixed into the grid clamping grooves from front to back, the first-stage grid is provided with a full-section grid, the second-stage grid is provided with a lower grid, the third-stage grid is provided with an upper grid, the fourth-stage grid is provided with a full-section grid, and the size of grid holes of the first-stage grid is larger than the size of grid holes of the second-stage grid, the size of grid holes of the third-stage grid and the size of grid holes of the fourth-stage grid. By means of graded filtering and trash holding, sundries can be cleaned easily, water flow is smooth, water resistance is stable, and normal operation of a unit is facilitated.
本发明属于工业建筑结构领域，提供了一种抽水蓄能电站进出水口拦污栅及其拦污栅系统，它解决了单层拦污栅造成的杂物堆叠效应对水流通畅的不利影响，其技术方案为：包括：多级格栅和用于固定各级格栅的格栅卡槽；多级格栅按照从前到后的顺序依次固定至格栅卡槽中，一级格栅上设置全断面格栅，二级格栅设置下部格栅，三级格栅上设置上部格栅，四级格栅上设置全断面格栅，一级格栅的格栅孔尺寸大于二级格栅、三级格栅和四级格栅的格栅孔尺寸。其通过分级过滤拦污，不仅有利于杂物的清理，而且水流通畅，水阻力较稳定，有利于机组的正常运行。
