Set up in front of the water inlet, it is used to block aquatic plants, driftwood and other debris (generally called dirt) carried by the water flow. ) frame-grid structure. The pollution rack is composed of a frame, a transverse partition and a grid (see picture). It is supported on a concrete pier wall and is generally made of steel. The spacing between the bars depends on the size, amount and application requirements of the dirt. The spacing between the bars used in hydropower stations It depends on the model and size of the turbine to ensure that the dirt passing through the waste rack will not be stuck in the flow-passing parts of the turbine. Generally, drainage tunnels and drainage holes are not equipped with waste racks. If the diameter of the hole or aperture is not large, When there is a lot of sunken wood that needs to be installed, the spacing between the bars should be increased. The load on the trash rack, in addition to its own weight, is mainly the water load caused by the water level difference between the front and rear of the rack after the dirt is blocked. Generally, it is considered based on the water head. .The size of the grid surface of the waste rack is determined by the flow rate and the allowable flow rate. In order to reduce the head loss and facilitate cleaning, it is generally required that the flow rate over the grid is not greater than about . The waste rack can be made fixed or can be lifted. . : >: ::: (,,)>Hoist
