[0041] The working principle and working process of the utility model are as follows: Specific embodiment one:

[0042] Before using the self-cleaning ultraviolet disinfector for water treatment, the staff will check each component one by one to see if there is any abnormality. The external pipe with a submersible pump installed at one end is connected to the water inlet 3 through a flange connector to ensure that the submersible pump is fixed at the bottom of the pool. The outlet pipe is connected to the water outlet 3 through a flange connector, and the other end of the pipe is introduced into a clean container. The distribution control box 26 and the submersible pump are electrically connected. The control switch of the ultraviolet lamp 6 in the distribution control box 26 is turned on, and the submersible pump is powered on. The water flow rate is controlled by controlling the speed of the submersible pump. The water in the pool is pumped into the water inlet, and the ultraviolet lamp 6 emits ultraviolet rays. Ultraviolet rays with a wavelength in the range of 200-280nm, especially ultraviolet rays in the band of 240-270nm, have the strongest bactericidal ability and can directly destroy the DNA of viruses, bacteria and spores in the water, making them lose their pathogenicity. Ultraviolet radiation will destroy the deoxyribonucleic acid and other related bond molecules, thereby preventing the replication and reproduction of microorganisms to achieve the purpose of sterilization. Specifically, ultraviolet rays can pierce the cell membrane, destroy the deoxyribonucleic acid and other molecules in the cell, so that the microorganisms can no longer replicate and reproduce, thereby achieving a disinfection effect. The ultraviolet lamp 6 is sleeved in the quartz sleeve 5. The water to be treated fully protects the ultraviolet lamp 6 from being eroded by sewage when flowing through the shell 1, greatly increasing the service life of the ultraviolet lamp 6 and reducing the cost. The water to be treated flows through the entire shell 1 and is fully sterilized by ultraviolet rays. The sterilized water is introduced into a clean container from the water outlet 4 through a pipeline. During the operation of the self-cleaning ultraviolet sterilizer, the toughened nylon seal 7 has better toughness, wear resistance, sealing and hygroscopicity, which can greatly improve the static sealing performance between the quartz sleeve 5 and the circular hole II 20. The cleaning rod I seal 13 is used for the dynamic sealing performance of the circular hole I 19 and the cleaning rod I 11. Specific embodiment 2:

[0043] After the self-cleaning ultraviolet disinfector has been working for a period of time, the staff will perform self-cleaning regularly. First, the submersible pump switch is turned off to stop the water inlet, and the water source in the shell 1 is kept sufficient. The double-acting cylinder 14 switch in the power distribution control box 26 is turned on. The double-acting cylinders 14 at both ends of the outer side of the shell 1 work at the same time, and the piston rods are extended by compressed air. The two piston rods simultaneously push the support frame 16 forward, and the support frame 16 simultaneously drives the cleaning rod Ⅰ11 and the cleaning rod Ⅱ12 to extend forward, and at the same time drives the front ends of the circular silicone cleaning pieces Ⅰ17 and the circular silicone cleaning pieces Ⅱ18 to slide. When the circular silicone cleaning piece Ⅰ17 slides to the front end of the shell 1 , the two double-acting cylinders 14 reach the preset extension length, and the two double-acting cylinders 14 simultaneously push the piston rod to retract through compressed air. Through the above actions, the circular silicone cleaning sheet I17 and the circular silicone cleaning sheet II18 slide back to the initial position, and the circular silicone cleaning sheet I17 and the circular silicone cleaning sheet II18 are tightly sleeved with the quartz sleeve 5. According to the above steps, the telescopic movement is repeated to clean the impurities adsorbed on the outer wall of the quartz sleeve 5. After cleaning, a sewage container is placed under the sewage outlet 29, and the cover plate 30 is opened with a bolt screwing tool, and the sewage in the housing 1 is placed in the sewage container, and the self-cleaning work is completed. During this period, the oblique silicone sealing ring 9 and the waterproof joint 10 cooperate with each other, which can greatly improve the dynamic sealing performance of the cleaning rod II12 and the circular hole III21. Specific embodiment three:

[0044] When the self-cleaning ultraviolet sterilizer is working, the staff can observe the working status of the ultraviolet lamp 6 in real time through the lamp observation window 8, and observe which ultraviolet lamp 6 has reduced brightness or no brightness, indicating that this ultraviolet lamp 6 has failed. The staff turns off the submersible pump switch to stop water intake, places a sewage container under the sewage outlet 29, uses a bolt tightening tool to open the cover 30, and puts the sewage in the shell 1 into the sewage container. After all the water in the shell 1 is drained, remove the quartz sleeve 5 that covers the damaged ultraviolet lamp 6, replace the new ultraviolet lamp 6, and then reinstall the quartz sleeve 5 in place, and work again according to the steps of the specific embodiment 1.
