DETAILED DESCRIPTION

The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

The utility model provides a technical solution: a waterproof drainage device with the function of filtering impurities in water. In this embodiment, as shown in Figures 1 and 2, a support rod 9 is arranged on the base 1, and a mounting plate 11 is arranged on the upper end of the support rod 9. An annular fixing plate 12 is rotatably arranged on the lower side of the mounting plate 11, and two inner and outer filter cartridges 8 are fixedly connected to the lower side of the fixing plate 12. Through the arrangement of the inner and outer filter cartridges 8, impurities in the water can be filtered for a second time during drainage, effectively improving the filtering effect. The fixing plate 12 is provided with a driving mechanism 5 to drive the rotation. A sewage collecting tank 2 is provided on the upper side of the base 1, and a U-shaped The scraper 3 is a U-shaped scraper 3, one side of the scraper 3 is in contact with the outer side walls of the two filter cartridges 8, a sewage pump 4 is installed on the upper side of the mounting plate 11, a sewage suction pipe 10 is installed at the input end of the sewage pump 4, and one end of the sewage suction pipe 10 is arranged in the sewage collecting tank 2. Through the arrangement of the U-shaped scraper 3, the outer side walls of the inner and outer filter cartridges 8 can be in contact with the side wall of the scraper 3. When the driving mechanism 5 drives the filter cartridge 8 to rotate, the impurities attached to the filter cartridge 8 can be scraped off by the scraper 3 and fall into the sewage collecting tank 2 on the lower side. The impurities scraped out by filtration in the sewage collecting tank 2 are discharged by the sewage pump 4, thereby avoiding the filtered impurities from clogging the filter cartridge 8 for the second time after cleaning.

As shown in Figure 2, the driving mechanism 5 includes a motor 502 installed on the upper side of the mounting plate 11, and the output end of the motor 502 is interference-connected with a gear 501, and the gear 501 is meshed with a gear ring 503. The gear ring 503 is arranged on the outer side of the fixed plate 12. When in use, the motor 502 is powered by an external power supply, so that the motor 502 drives the gear 501 at the output end to rotate. When the gear 501 rotates, the gear ring 503 meshed with it will be driven by the gear 501 to rotate, and then the fixed plate 12 drives the two filter cartridges 8 to rotate synchronously, thereby facilitating the function of removing impurities attached to the surface of the filter cartridge 8.

As shown in Figures 1 and 2, a threaded portion is provided at the upper end of the support rod 9, and the threaded portion of the support rod 9 passes through the mounting plate 11. The threaded portion at the upper end of the support rod 9 is threadedly connected with a locking nut 7. The position of the mounting plate 11 can be fixed by using the locking nut 7 screwed on the threaded portion at the upper end of the support rod 9, thereby increasing the stability of the equipment.

As shown in Figures 2 and 3, a water pump 6 is installed at the center of the upper side of the mounting plate 11. The input end flange of the water pump 6 is connected to a water pipe 13. The lower end of the water pipe 13 extends to the bottom of the internal filter cartridge 8. Through the setting of the water pump 6, the sewage filtered by the inner and outer filter cartridges 8 can be pumped out through the water pipe 13.

As shown in Figures 1 and 4, a limiting groove 14 adapted to the filter cartridge 8 is opened on the upper side of the base 1, and the lower end of the filter cartridge 8 is slidably set in the limiting groove 14. Through the setting of the limiting groove 14, the position of the filter cartridge 8 can be limited to prevent the filter cartridge 8 from shifting during rotation.

The utility model provides a waterproof drainage device with the function of filtering impurities in water. The specific working principle is as follows: through the inner and outer filter cartridges 8 arranged on the lower side of the fixed plate 12, impurities in the water can be filtered twice, thereby effectively improving the function of filtering impurities in the water. Through the arrangement of the U-shaped scraper 3, the outer side walls of the inner and outer filter cartridges 8 can be fitted with the side walls of the scraper 3. When the driving mechanism 5 drives the filter cartridge 8 to rotate, the impurities attached to the filter cartridge 8 can be scraped off by the scraper 3 and fall into the sewage collection tank 2 on the lower side. The impurities scraped out by the filtration in the sewage collection tank 2 are discharged by the sewage pump 4, thereby avoiding the clogging of the filter cartridge 8 by the filtered impurities after cleaning.
