[0001] This utility model relates to the field of water tank self-cleaning technology, specifically a water tank self-cleaning disinfection device. Background Technology

[0002] Currently, water tanks are often used to store water in industrial production and daily life. However, due to long-term stagnation, the water in the tanks is subject to varying degrees of bacterial and microbial contamination, posing a threat to people's daily water use. Therefore, it is necessary to disinfect and sterilize the water regularly.

[0003] As disclosed in the patent announcement CN211310932U, a self-cleaning disinfection device for water tanks includes a hollow water tank body. A water pump is placed on the bottom inner wall of the water tank body. The same baffle is fixedly installed on the top and bottom inner walls of the water tank body. A disinfection box with a hollow structure is fixedly installed on the top inner wall of the water tank body, and the water pump's suction pipe extends into the disinfection box. The beneficial effects of this utility model using the above technical solution are: simple structure, convenient operation, and the ability to quickly and easily automatically clean ultraviolet lamps while simultaneously discharging the cleaned impurities, greatly solving the problem of difficult cleaning of ultraviolet lamps and thus meeting people's needs.

[0004] While the aforementioned patent enables quick and convenient automatic cleaning of ultraviolet lamps, it requires an additional motor to drive the lead screw, which increases energy consumption during operation. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1-4 As shown, this utility model provides a technical solution:

[0026] The water tank self-cleaning sterilizer includes a sterilization tank 1, inside which a sterilization mechanism is arranged side-by-side at the top. The sterilization mechanism includes several ultraviolet lamps 3 fixedly arranged side-by-side at the upper part of the inside of the sterilization tank 1, and a controller 4 fixedly installed at the upper part of the outside of the sterilization tank 1. The controller 4 is electrically connected to the ultraviolet lamps 3, and a cover plate is detachably installed on the top of the controller 4 by bolts. An overflow port 18 is provided between the upper part of the filter box 2 and the sterilization tank 1. A liquid level sensor 19 is fixedly installed at the left corner of the front of the sterilization tank 1. The liquid level sensor 19 is electrically connected to a high-pressure water pump 8 through a PLC. The liquid level sensor 19 monitors the water level in the sterilization tank 1. When the water level is lower than the set value, the PLC controls the high-pressure water pump 8 to start replenishing water. Inside the sterilization tank 1 and outside the sterilization mechanism, a rotating cleaning mechanism is arranged. The rotating cleaning mechanism includes several drive shafts 5 rotatably connected to the upper part of the right inner wall of the sterilization tank 1 through bearings, and a drive plate 6 fixed to the outer periphery of the drive shafts 5 with equal arc. The end of the drive plate 6 near the ultraviolet lamps 3 is rotatably connected to the filter box 1 through bearings. A cleaning brush 7 is attached, which contacts the outer wall of the ultraviolet lamp tube 3. The rotating cleaning mechanism also includes a high-pressure water pump 8 fixedly installed below the front of the disinfection box 1, and a vertical pipe 9 connected to the output end of the high-pressure water pump 8. A horizontal pipe 10 is fixedly installed at the top of the vertical pipe 9 through a three-way valve. Several diversion pipes 11 are arranged side by side at the other end of the horizontal pipe 10. The other end of the diversion pipe 11 extends to the upper end of the drive plate 6 and is fixedly installed with a vertical high-pressure nozzle 20. A water inlet pipe 1 is fixedly installed at the input end of the high-pressure water pump 8. 2. A filter box 2 is fixedly installed on the outside of the right side of the disinfection box 1. A filter mechanism is provided inside the filter box 2. The filter mechanism includes a mounting groove 13 opened in the middle of the top of the filter box 2 and a mounting bracket 14 set at the top of the filter box 2. A filter screen 15 is fixedly installed in the middle of the bottom end of the mounting bracket 14. The bottom end of the filter screen 15 extends into the interior of the filter box 2 and contacts its inner bottom wall. A handle 16 is fixedly installed at the top of the mounting bracket 14. A return water pipe 17 is fixedly installed at the bottom right side of the filter box 2.

[0027] In this embodiment, the high-pressure nozzle 20 driven by the high-pressure water pump 8, in conjunction with the rotatable drive plate 6, achieves the effect of continuously cleaning the ultraviolet lamp tube 3 by automatically driving the cleaning brush 7 with water power. This solves the problem of increased energy consumption caused by the need for additional motors in the prior art, and realizes energy-saving operation.

[0028] Furthermore, by using the filter screen 15 installed in the filter box 2 in conjunction with the circulating water circuit, the effect of filtering impurities in the circulating disinfectant water is achieved. At the same time, it can effectively intercept the dirt that falls off during the cleaning process of the ultraviolet lamp tube 3, ensuring the cleanliness of the disinfectant water.

[0029] Working principle: The disinfection box 1 is connected to the external water tank through the inlet pipe 12 and the return pipe 17 to form a circulating disinfection system. The ultraviolet lamp 3 at the upper end of the disinfection box 1 starts the sterilization function under the control of the controller 4. The water flows into the high-pressure water pump 8 through the inlet pipe 12, and is divided into each branch pipe 11 through the vertical pipe 9 and the horizontal pipe 10. Finally, it is sprayed out through the high-pressure nozzle 20 to form a high-pressure water flow. The high-pressure water flow impacts the drive plate 6, causing it to drive the drive shaft 5 to rotate. The cleaning brush 7 at the end of the drive plate 6 rotates accordingly and scrapes and cleans the outer wall of the ultraviolet lamp 3 to ensure that there is no dirt accumulation on the surface of the lamp. The filter box 2 receives the water overflowing from the disinfection box 1 through the overflow port 18. After being filtered by the filter screen 15, the water flows back to the water tank through the return pipe 17. The liquid level sensor 19 monitors the water level in the disinfection box 1 in real time. When the water level is lower than the set value, the PLC automatically starts the high-pressure water pump 8 to replenish water from the outside.
