[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] A self-cleaning spiral fin tube, such as Figure 3 , 4 As shown, it includes a U-shaped frame 1 and a base tube 3. One end of the U-shaped frame 1 is provided with multiple groups of scrapers 103. The end of the scraper 103 is set in an arc shape. The head and the end of the U-shaped frame 1 are fixed with semicircular rings 101, which rotate along the base tube 3. The semicircular ring 101 drives the U-shaped frame 1 to rotate. A second slide groove 104 is provided in the middle of the scraper 103. The outer side of the scraper 103 is slidably connected with a scraper ring 2. The U-shaped frame 1 drives the scraper 103 to rotate, so that the scraper 103 scrapes impurities on the surface of the base tube 3 and the fin 301.

[0023] The semicircular ring 101 rotates along the base tube 3, driving the U-shaped frame 1 to rotate, so that the scraper 103 scrapes off the impurities on the surface of the base tube 3 and the fins 301, without disassembling the base tube.

[0024] Both sides of the scraper ring 2 are provided with fixed rods 201, and the pull block 202 is pulled up and down, and the pull block 202 drives the fixed rod 201 up and down, and the fixed rod 201 is slidably connected to the inside of the No. 2 slide groove 104, and the head end and the end of the fixed rod 201 are fixed with the pull block 202, and the other end of the U-shaped frame 1 is fixed with a handle 105, and both sides of the outer side of the U-shaped frame 1 are provided with the No. 1 slide groove 102, and the pull block 202 is slidably connected to the inside of the No. 1 slide groove 102, and the fixed rod 201 drives the scraper ring 2 up and down, so that the scraper ring 2 scrapes off the impurities left on the surface of the scraper 103;

[0025] The pulling block 202 drives the fixing rod 201 to move up and down, so that the scraper ring 2 scrapes off the impurities remaining on the surface of the scraper plate 103 .

[0026] It should be noted that, by rotating along the base tube 3, the semicircular ring 101 drives the U-shaped frame 1 to rotate, and the U-shaped frame 1 drives the scraper 103 to rotate, so that the scraper 103 scrapes off the impurities on the surface of the base tube 3 and the fin 301, and there is no need to disassemble the base tube. After the scraper 103 scrapes, impurities will remain on the surface of the scraper 103, and the pulling block 202 is pulled up and down, and the pulling block 202 drives the fixed rod 201 up and down, and the fixed rod 201 drives the scraper ring 2 up and down, so that the scraper ring 2 scrapes off the impurities remaining on the surface of the scraper 103.

[0027] Please pay attention to Figure 1 , 2 A plurality of fins 301 are arranged on the outside of the base tube 3, and mounting brackets 402 are arranged at both ends of the outside of the base tube 3. The mounting brackets 402 are convenient for taking out the base tube 3. A thread 4 is arranged on the outside of the base tube 3 on one side of the mounting bracket 402. The nut 401 is rotated to fix the base tube 3 in the mounting bracket 402, and a nut 401 is arranged on the outside of the thread 4.

[0028] It is understandable that the base pipe 3 can be easily taken out through the mounting frame 402 , and the nut 401 can be turned to fix the base pipe 3 in the mounting frame 402 .

[0029] Working principle: The semicircular ring 101 and the scraper 103 are brought into contact with the surface of the base tube 3 and the fin 301, and rotate along the base tube 3. The semicircular ring 101 drives the U-shaped frame 1 to rotate, and the U-shaped frame 1 drives the scraper 103 to rotate, so that the scraper 103 scrapes away impurities on the surface of the base tube 3 and the fin 301, without disassembling the base tube;

[0030] After the scraper 103 is scraped, impurities will remain on the surface of the scraper 103. The pull block 202 is pulled up and down, and the pull block 202 drives the fixed rod 201 up and down, and the fixed rod 201 drives the scraper ring 2 up and down, so that the scraper ring 2 scrapes off the impurities left on the surface of the scraper 103.

[0031] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
