The servo motor 2 is installed at the top center of the water tank body 14 , and the sealing cover 4 is installed on the left side of the servo motor 2 . The output shaft of the servo motor 2 is connected to the threaded rod 13 .

[0019] according to Figure 3 As shown, an N-type semiconductor and a P-type semiconductor are installed inside the heating ring 9, and the two ends of the N-type semiconductor are electrically connected to the metal sheet A and the metal sheet B respectively, and the two ends of the P-type semiconductor are electrically connected to the metal sheet A and the metal sheet B respectively. The N-type semiconductor, the P-type semiconductor, the metal sheet A and the metal sheet B form a ring-shaped closed circuit. The metal sheet A is located in the heating ring 9, the metal sheet B is located in the servo motor 2, and the metal sheet B and the servo motor 2 are electrically connected to a power supply.

[0020] according to Figure 2 As shown, a pipeline is opened in the connecting rod 18, and a nozzle 17 is opened at the connection between the connecting rod 18 and the scraper ring 10. The nozzle 17 is connected to the pipeline, and the cleaning tank 16 is connected to the pipeline.

[0021] according to Figure 3 and Figure 4 As shown, a metal strip is installed on the scraper 12, and a solenoid valve A and a current sensor are installed inside the cleaning tank 16, and the current sensor is electrically connected to the metal strip.

[0022] according to Figure 2 , Figure 3 and Figure 4 As shown, there are four connecting rods 18 , and a circle of brushes 8 is installed on the outside of the scraper ring 10 .

[0023] according to Figure 1 and Figure 5As shown, a water inlet pipe 3 is installed on the top of the outer wall of the water tank body 14 , a filter screen 15 is installed in the water inlet pipe 3 , and the diameter of the water inlet pipe 3 is consistent with the height of the heating ring 9 .

[0024] according to Figure 1 As shown, a sewage pipe 1 is installed at the bottom of the outer wall of the water tank body 14, and a solenoid valve B is installed in the sewage pipe 1 to control the opening and closing of the sewage pipe.

[0025] according to Figure 1 As shown, a water pump 6 is installed on the left side of the water tank body 14, and the water pump 6 is connected to the water tank body 14. The water pump 6 is installed with a drain pipe 5, and a drain flange 7 is installed at the outlet of the drain pipe 5.

[0026] Working principle: The staff observes through the top sealing cover 4 that the inner wall of the water supply equipment is covered with water rust and scale. When it is determined that the water supply equipment needs to be cleaned, the staff opens the drain pipe 5, first discharges the water in the water tank body 14 through the drain pipe 5, opens the sewage pipe 1, turns on the power, and starts the servo motor 2. The output shaft of the servo motor 2 drives the threaded rod 13 to rotate. The rotation of the threaded rod 13 drives the matching circular rings to move up and down along the threaded rod 13. The circular ring drives the connecting rod 18 to move up and down. The connecting rod 18 drives the scraper ring 10 to move up and down. The brush 8 on the outside of the scraper ring 10 moves up and down to brush off the water rust and scale on the inner wall of the water tank body 14. Part of the water rust and scale falls on the bottom of the water tank body 14. The rotation of the threaded rod 13 drives the scraper 12 at the bottom to rotate. The scraper 12 continuously scrapes the water rust and scale that falls on the bottom into the sewage pipe 1 for discharge. When the power is turned on, the heating ring 9 is energized, and the current flows from the N-type semiconductor through the metal sheet B to the P-type semiconductor. The metal sheet B absorbs heat. The metal sheet B is located in the servo motor 2 to help the servo motor 2 reduce the temperature. The current flows from the P-type semiconductor through the metal sheet A to the N-type semiconductor. The metal sheet A releases heat. The metal sheet A is located in the heating ring 9. The heating ring 9 starts to heat some stubborn rust and scale around it, making it easier for the brush 8 to brush it off. The N-type semiconductor, the metal sheet A, the P-type semiconductor, the metal sheet B and the power supply form a ring circuit to generate a magnetic field. When the heating ring 9 moves to the bottom, the scraper 12 keeps rotating, and the metal strip on the scraper 12 cuts the magnetic field to generate a weak current, which is captured by the current sensor in the cleaning tank 16. The solenoid valve A in the cleaning tank 16 opens, and the detergent in the cleaning tank 16 is sprayed out from the nozzle 17 through the pipeline inside the connecting rod 18. A part of the detergent is sprayed on the inside of the water tank body 14, and a part is sprayed on the brush 8, thereby improving the cleaning efficiency. When the heating ring 9 moves to the top, open the water inlet pipe 3 and flush water into the water tank body 14. Since the height of the heating ring is the same as the diameter of the water inlet pipe, the tap water flushes on the heating ring 9 and flows along the heating ring 9 to the brush 8, flushing away the rust and scale remaining on the brush 8.
