A welding pipe passes between two first cleaning brushes 7, and the surface of the welding pipe is brushed by friction between the welding pipe and the first cleaning brushes 7. The first cleaning brushes 7 are located inside the first housing 1. Multiple third arc panels 10 are rotatably connected to both sides of the lower rod 4. A sealing element is bolted to the inner side of each third arc panel 10.

[0033] Multiple support rods 14 are bolted between the inner walls of the two sides of the third housing 3. A heating element 15 is bolted to the top of the support rods 14. A fixing shell 16 is inserted into the top of the third housing 3. A mounting bracket 17 is bolted inside the fixing shell 16. A blower 18 is bolted to the bottom of the mounting bracket 17. The heating element 15 heats the air inside the third housing 3, and then the blower 18 blows the air onto the welding pipe to dry it. A dustproof net 19 is clipped to the top of the fixing shell 16 to prevent dust from entering the third housing 3. Two fixing plates 20 are bolted to the bottom outer walls of the first housing 1, the second housing 2, and the third housing 3. A water box 21 is bolted to the bottom of the two fixing plates 20. Water from the welding pipe falls into the water box 21 for collection. A frame is bolted to the bottom outer wall of the water box 21. 22. A vacuum cleaner 23 is bolted to the bottom inner wall of the frame 22. The dust inlet of the vacuum cleaner 23 is connected to a guide cover 24 through a connecting pipe. The guide cover 24 is clipped onto the top of the first housing 1. Under the action of the vacuum cleaner 23, the debris is sucked up through the guide cover 24. A water tank 25 is bolted to the bottom inner wall of the frame 22. A pump body 26 is bolted to one side outer wall of the water tank 25. The water inlet of the pump body 26 is connected to the water tank 25. A single-ended sealing pipe 27 is inserted into the water outlet of the pump body 26. Multiple connecting hoses 28 are inserted into the bottom of the single-ended sealing pipe 27. The other end of the connecting hoses 28 is inserted into the sealed water distribution box 11. The welded pipe passes between the two sealed water distribution boxes 11. Under the action of the pump body 26, the water in the water tank 25 is input into the single-ended sealing pipe 27, and then into the sealed water distribution box 11 through the connecting hoses 28. Then, it is sprayed out from the nozzle 12, thereby wetting the welded pipe.

[0034] The working principle of this embodiment is as follows: In use, firstly, the polished welded pipe is inserted into the first housing 1 from one side and pushed inwards, allowing it to pass between the two first cleaning brushes 7. The friction between the welded pipe and the first cleaning brushes 7 brushes the surface of the pipe. Simultaneously, the vacuum cleaner 23 removes debris through the guide cover 24. Next, the welded pipe is pushed into the second housing 2, passing between the two sealed water distribution boxes 11. Under the action of the pump 26, water from the water tank 25 is input into the single-ended sealed pipe 27. The connecting hose 28 is fed into the sealed water distribution box 11, and then sprayed out from the nozzle 12 to wet the welded pipe. Then, the welded pipe passes between the two second cleaning brushes 9, and the welded pipe is brushed a second time by friction between the welded pipe and the second cleaning brushes 9. Then, the welded pipe is rinsed by the nozzle 12. Then, the welded pipe is pushed into the third box 3, and the air in the third box 3 is heated by the heating body 15. Then, the air is blown onto the welded pipe by the blower 18 to dry the welded pipe. Finally, the welded pipe exits from one side of the third box 3.

[0035] When maintenance is required on the first cleaning brush 7, the second cleaning brush 9, and the nozzle 12, the first arc panel 6, the second arc panel 8, and the third arc panel 10 open outwards under the action of the retraction of the electric push rod 13, thereby facilitating maintenance of the first cleaning brush 7, the second cleaning brush 9, and the nozzle 12.

[0036] Example 2

[0037] Referring to Figure 7, a weld grinding and cleaning mechanism includes a first housing 1, a second housing 2, and a third housing 3, each with openings on both sides. Multiple guide wheels 29 are rotatably connected to the inner circumference of each opening. The guide wheels 29 are designed to facilitate the pushing of the welded pipe and reduce wear on the welded pipe. A transparent plate 30 is embedded on one side of each of the first housing 1, the second housing 2, and the third housing 3. A vibration motor 31 is bolted to the outer wall of one side of the first housing 1 and the second housing 2. The vibration motor 31 drives the first housing 1 and the second housing 2 to vibrate, thereby increasing the friction between the welded pipe and the first cleaning brush 7 and the second cleaning brush 9, thus improving the cleaning effect of the welded pipe. A connecting frame 32 is bolted to the top of the third housing 3, and a protective cover 33 is bolted to the top of the connecting frame 32. The connecting frame 32 and the protective cover 33 protect the top of the third housing 3.

[0038] The working principle of this embodiment is as follows: When in use, the design of the guide wheel 29 facilitates the pushing of the welded pipe and reduces the wear of the welded pipe. Then, the vibration motor 31 drives the first box 1 and the second box 2 to vibrate, thereby increasing the friction between the welded pipe and the first cleaning brush 7 and the second cleaning brush 9. Then, the top of the third box 3 is protected by the connecting frame 32 and the protective cover 33.
