[0014] Compared with the prior art, the present invention has the following beneficial effects: 1.

[0015] 2. When the reverse osmosis RO membrane cleaning device is in use, the water after flushing enters the water bucket through the inlet pipe, and enters the gear pump through the connecting pipe after being filtered by the filter cartridge.

If the water pressure in the connecting pipe 21 is low, the motor 3 26 is turned on, and the motor 3 26 drives the screw plate 24 to clean the filter through the support rod 25. The cylinder 23 performs scraping and cleaning work, and pushes the scraped impurities to the inside of the drain pipe 27 until the water level gauge 16 monitors the water level, then opens the electric valve 28, discharges the impurities and part of the sewage through the drain pipe 27, and controls the opening of the electric valve 28 through the water level gauge 16 to ensure that the amount of water entering the box body 1 through the reverse osmosis RO membrane is equal to the amount of impurities and sewage discharged from the drain pipe 27. Under the water pressure of the water pump 17, the reverse osmosis RO membrane is prevented from entering the inside of the reverse osmosis RO membrane, thereby effectively preventing the inside of the reverse osmosis RO membrane from being dirty, and preventing the cleaned water from penetrating into the reverse osmosis RO membrane again under the water pressure, thereby ensuring the cleaning effect of the reverse osmosis RO membrane. When the water in the box body 1 reaches the position of the water level gauge 16,A part of the cleaning water passes through the discharge pipe 27 and drives the impurities cleaned by the screw plate 24 to be discharged outward. Most of the water is filtered by the filter cartridge 23, then sucked into the gear pump 20 through the connecting pipe 21, and pumped into the nozzle 29 through the conduit 22, and then sprayed to the outer side of the reverse osmosis RO membrane through the nozzle 30. The motor 36 drives the scraper 32 to move left and right on the inner side of the box body 1 through the screw rod 37 to scrape and clean the inner side of the box body 1. As the pure water enters the box body 1 through the reverse osmosis RO membrane, the reverse osmosis RO is ensured. Under the water circulation work of cleaning the outside of the membrane, the sewage in the box 1 and the bucket 18 is gradually discharged outward until the water in the box 1 and the bucket 18 becomes clean. When cleaning the reverse osmosis RO membrane, the box 1, the bucket 18 and the filter cartridge 23 can be automatically cleaned to ensure that the box 1, the bucket 18 and the filter cartridge 23 are kept clean and sanitary after the work is completed, which can not only prevent the reverse osmosis RO membrane after cleaning from being soiled by the equipment again, but also ensure the work efficiency and cleaning effect of cleaning the next reverse osmosis RO membrane.
