[0026] The above scheme is adopted: hydraulic power is provided by the setting of the hydraulic cylinder 201, and the entire cleaning mechanism 2 is driven to move up and down by controlling the extension and contraction of the hydraulic cylinder 201. The setting of the connecting plate 202 facilitates the installation of the slide 203 and the slider 204, and plays a supporting and transmission role. The setting of the slide 203 is used to guide and limit the movement trajectory of the slider 204.

The hydraulic cylinder 201 is telescopically transmitted to the slider 204, and the slider 204 is in the slider 204. The cleaning disc 206 on the rotator 205 rotates accordingly, and the dirt on the surface of the filter screen 302 is scraped off by the movement of the cleaning disc 206. The water filtered by the water inlet pump 6 is further purified by the purification box 7. The working status, water pressure and other parameters of the water pump 6 are monitored by the sensor 403, and the electric water outlet valve 13 is started. The filtered and purified tap water enters the water supply network inside the building through the water outlet pipe 11 through the electric water outlet valve 13.
