Under the limiting action of the straight rod, the first slide plate drives the brush plate to slide along the outer wall of the first screw rod, so that the cleaning brush on the side wall of the brush plate cleans the inner wall of the water tank body. The motor drives the first screw rod to rotate forward and reverse to achieve reciprocating cleaning of the inner wall of the water tank body by the cleaning brush. During the rotation of the first screw rod, the scraper mechanism is driven by the first bevel gear to clean the inner wall of the bottom end of the water tank body, thereby reducing the trouble of manually cleaning the inside of the water tank body.

The air pipe 441 is connected to the inside of the cavity 335. The cam 45 is fixedly connected to the side wall of the first screw rod 21 extending outside the water tank body 1. The cam 45 can cooperate with the arc surface 421 to push the pressure block 42 to slide toward the inside of the concave shell 41.

[0056] The first screw rod 21 drives the cam 45 to rotate during rotation. When the cam 45 contacts the arc surface 421 on the pressure block 42, the cam 45 pushes the pressure block 42 to slide toward the inside of the concave shell 41. The pressure block 42 squeezes the air bag 44 so that the gas inside the air bag 44 is transported to the cavity 335 through the air pipe 441. When the cam 45 loses contact with the arc surface 421, the pressure block 42 is reset under the elastic force of the second spring 43, so that the cam 45 can squeeze the pressure block 42 again.

[0057] Working principle: water is delivered to the water tank body 1 through the water delivery device 14 so that the water tank body 1 stores domestic water; the water stored in the water tank body 1 is delivered to the water supply area of ​​the middle-level residential buildings through the first drainage pipe 15 through the first variable frequency water supply device 5, and the water stored in the water tank body 1 is delivered to the water supply area of ​​the high-level residential buildings through the second drainage pipe 16 through the second variable frequency water supply device 6. The first vortex preventer 151 and the second vortex preventer 161 are arranged so that vortex is not easily generated during water delivery;

[0058] When the water tank body 1 stores water, the overflow pipe 18 limits the water level. When the water level is higher than the upper end surface of the overflow pipe 18, the water will be discharged from the water tank body 1 through the overflow pipe 18, so that the water tank body 1 is not easy to store excessive water. The second filter 181 is set to filter dust and impurities, reducing the possibility of external impurities entering the water tank body 1 through the overflow pipe 18.

[0059] The water level gauge 7 and the static pressure level gauge 8 are used to detect the water level of the water source inside the water tank body 1, so as to facilitate the understanding of the water level inside the water tank; the arrangement of the vent pipe 17 keeps the pressure inside the water tank body 1 stable, and the first filter 171 arranged on the inner wall of the vent pipe 17 filters dust and impurities, thereby reducing the possibility of water source being polluted;

[0060] When cleaning the inside of the water tank body 1, the motor 2 is started to drive the first screw rod 21 to rotate. Under the limiting action of the straight rod 25, the first slide plate 22 drives the brush plate 23 to slide along the outer wall of the first screw rod 21, so that the cleaning brush 24 cleans the inner wall of the water tank body 1. The motor 2 drives the first screw rod 21 to rotate forward and reversely to achieve reciprocating cleaning of the inner wall of the water tank body 1 by the cleaning brush 24. During the rotation of the first screw rod 21, the first bevel gear 26 drives the second bevel gear 32 and the second screw rod 31 to rotate, so that the scraper 33 cleans the dirt adhered to the inner wall of the bottom end of the water tank body 1 during the sliding process along the outer wall of the second screw rod 31, so that the scraper 33 reciprocates to scrape off the dirt adhered to the inner wall of the bottom end of the water tank body 1, thereby reducing the trouble of manually cleaning the inside of the water tank body 1.

[0061] The first screw rod 21 rotates and drives the cam 45 to rotate. When the cam 45 contacts the arc surface 421 on the pressing block 42, the cam 45 pushes the pressing block 42 to slide toward the inside of the concave shell 41. The pressing block 42 squeezes the airbag 44 so that the gas inside the airbag 44 is transported to the cavity 335 through the air pipe 441 to push the second slide plate 336 to slide down. The second slide plate 336 drives the connecting rod 337 to push the straight plate 332 to slide down and compress the first spring 333. During the sliding process, the straight plate 332 drives the push plate 334 to slide along the outer surface of the scraper 33. The side wall slides down, so that the push plate 334 scrapes off the dirt adhered to the outer wall of the scraper 33, reducing the possibility of dirt adhering to the scraper 33. When the cam 45 loses contact with the arc surface 421, the pressing block 42 is reset under the elastic force of the second spring 43, so that the cam 45 can squeeze the pressing block 42 again. In the process of the cam 45 squeezing the pressing block 42 back and forth, the push plate 334 scrapes the outer wall of the scraper 33 back and forth, so that the scraper 33 can better clean the inner wall of the bottom end of the water tank body 1.

[0062] When the cleaning brush 24 cleans the inner wall of the water tank body 1, an external water pump is connected to the water inlet pipe 11, and the first valve 111 is opened. Clean water is transported from the water inlet pipe 11 to the water pipe 231 through the water pump. The water entering the water pipe 231 is finally sprayed out through the water nozzle 232 to flush the inner wall of the water tank body 1 and improve the cleaning effect of the inner wall of the water tank body 1. After the cleaning is completed, the third valve 191 is opened to discharge the sewage inside the water tank body 1 through the drain pipe 19.

[0063] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
