Description

Technical Field

[0001] The invention relates to the field of pollution blocking, in particular to a pollution blocking component for a water inlet of a pumped storage power station. Background Art

[0002] Pumped storage power stations are a way of generating electricity using hydroelectric power. The working principle is to build two reservoirs between high altitude and low altitude, and control the flow of water through the power grid, so that water flows from high altitude to low altitude, while driving turbine generators to generate electricity. When it is necessary to store electrical energy, the power grid inputs electrical energy into turbine generators and pumps water to the high reservoir to form an energy storage state. This method can both regulate the load of the power system and store a large amount of electrical energy.

[0003] When building an energy storage station in a small reservoir with a small area, a water storage tank is usually set up at the pumping station. The water is mainly treated before being pumped out by a water pump. Due to pollution, there are often garbage bags, dead leaves, and filamentous floating moss on the water surface. The existing solution is to set a floating net inside the pool to intercept the floating objects on one side of the float. However, when there are too many floating moss and garbage bags and they accumulate, they will naturally flow with the suction water, pass through the floating net, and be sucked into the pumping station, affecting the use of the pumping station; and it is difficult to fully clean them by regular salvage, and the salvage tools need to be manually cleaned during the salvage process, which makes the salvage operation more labor-intensive. Therefore, we need to optimize the existing design. Summary of the invention

Driven by the rotation of the baffle 15, the floating objects fall into the processing bucket 4 for temporary storage, and under the setting of the inclined shape of the filter station 5, part of the floating objects fall into the arc bucket 12 with the enclosure of the mounting rod 21. At this time, the hydraulic cylinder 16 can drive the frame rod 17 to move back and forth, causing the two opposing anti-flow plates 19 set at the lower end U-shaped frame 18 to guide the floating objects inside the arc bucket 12 so that all the retained floating objects fall into the processing The reciprocating movement of the frame rod 17 inside the bucket 4 will correspond to the squeezing of the piston rod 32 on the outer sides of both sides, so that the piston rod 32 cooperates with the piston cylinder 31 to squeeze the air inside the piston cylinder 31, so that the air flow pressure is delivered to the inner side of the connecting pipe 33, and then delivered to the inside of each processing box 35 by the connecting pipe 33, and finally, the air flow is sprayed on the surface of the filter plate 8 through the multiple extension holes 34 and air holes 36 extending from the inside of the processing box 35, so that the floating objects attached to it can reduce the wall hanging, so as to promote the faster circulation of water inside the processing bucket 4, and the uninterrupted rotation of the baffle rod 15 will adhere to some of the silky floating moss and garbage bags, which can be driven by the two-way telescopic rod 26 to cause the scraper frame 30 under the sliding rod 27 to fit the surface of the baffle rod 15 for scraping, so that it can automatically clean the baffle rod 15 that blocks dirt, greatly blocking the inflow of dirt, and at the same time automatically collecting the dirt and processing the original tools for treatment, which greatly improves the working efficiency of the water treatment in the pump station and reduces the labor burden of the operator.
