Description

Technical Field

[0001] The utility model belongs to the field of filtering devices, in particular to a sewage filtering device for a pumped storage power station. Background Art

[0002] Pumped-storage power stations were created to resolve the contradiction between supply and demand between peak and trough times in the power grid. They are a way of indirectly storing electrical energy. They use excess electricity in the second half of the night to drive water pumps to pump water from the lower reservoir to the upper reservoir for storage, and then release the water to generate electricity during the day and first half of the night the next day, and the water flows into the lower reservoir. During the entire operation process, although some energy will be lost during the conversion, by comparison, the use of pumped-storage power stations is still cheaper and more efficient than adding coal-fired power generation equipment to meet peak electricity demand and overloading or shutting down during trough times. Pumped-storage power stations have two main operating modes: power generation and pumping. Between the two operating modes, there are many operating modes for switching from one operating condition to another.

[0004] However, during the use of the existing sewage filtering device of the pumped storage power station, since the water contains a large amount of garbage, a filtering device is needed to separate the garbage in the water when the water is pumped by the pumped storage power station. However, after separating the garbage, the filtering device is unable to collect the garbage and discharge it out of the water diversion trough, resulting in the need for staff to clean it regularly, thereby increasing the workload of the staff.

[0005] Therefore, those skilled in the art have proposed a sewage filtering device for a pumped storage power station to solve the problems raised by the background technology. Utility Model Content

[0013] Preferably, the collecting net and the filtering net are both in mesh structure, and the mesh sizes of the collecting net and the filtering net are the same.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The utility model provides a collecting frame, a collecting net and a cleaning scraper. When the sewage filtering device of the pumped storage power station is used, water will flow into the water diversion trough. At this time, the water will pass through the filter net, and the garbage in the water will be blocked on the filter net. When a certain amount of garbage is blocked, the lifting motor drives the lifting screw rod to rotate, and the lifting nut seat drives the collecting net to move up and down through the collecting frame, and the cleaning scraper will scrape the garbage blocked on the filter net and collect it in the collecting frame and the collecting net.
