The bottom end of the high-pressure water nozzle 46 is fixedly connected to a riser pipe 45, and the bottom end of the riser pipe 45 is fixedly connected to a connecting arc pipe 43. The scraping assembly 5 includes a movable plate 51, an electric telescopic rod 52 is fixedly connected to the inner side of the movable plate 51, a limit telescopic rod 53 is fixedly connected to one side of the movable plate 51, a partition column 54 is fixedly connected to the top of the movable plate 51, an extension plate 55 is fixedly connected to the top of the partition column 54, an airbag 57 is fixedly connected to the outer side of one end of the movable plate 51, a rubber sheet 56 is fixedly connected to one side of the movable plate 51, and a rubber protective sleeve 58 is fixedly connected to the outer side of the rubber sheet 56.

[0031] As a further implementation of this solution, the limiting component 3 includes a base plate 31, a servo motor 32 fixedly connected to the inner side of the base plate 31, a turntable 33 fixedly connected to the end of the main shaft of the servo motor 32, a reserved screw hole 34 opened on the inner side of the turntable 33, the reserved screw hole 34 opened on the base plate 31 is fixed to the rigid plate 35 by bolts, an arc-shaped clamping plate 36 is fixedly connected to one side of the rigid plate 35, one side of the arc-shaped clamping plate 36 is in close contact with the inner side of the bicycle rim body 1, there are two arc-shaped clamping plates 36, one end of the arc-shaped clamping plate 36 is arc-shaped, a threaded hole is opened on the inner side of the limiting telescopic rod 53, the bottom end of the rigid plate 35 is in contact with the top end of the turntable 33, and multiple reserved screw holes 34 are set, which can fix the bicycle rim body 1. At the same time, through the gap fit between the arc-shaped clamping plate 36 and the inner side of the bicycle rim body 1, it is convenient to drive the bicycle rim body 1 to rotate through the servo motor 32 and the turntable 33.

[0032] As a further implementation of this solution, the left side of the base plate 31 is fixedly connected to the right side of the water tank 41. The inside of the water tank 41 is hollow. A through hole is opened inside the water inlet pipe of the water tank 41 near the water pump 42. The water inlet pipe of the water tank 41 is located inside the water tank 41. The water outlet pipe of the water pump 42 is connected to the inside of the connecting arc pipe 43. The inside of the riser pipe 45 is hollow. A through hole is opened on the inside of the high-pressure water nozzle 46 near the inside of the riser pipe 45. The inside of the riser pipe 45 is connected to the inside of the high-pressure water nozzle 46. The inside of the connecting arc pipe 43 is connected to the inside of the riser pipe 45. The high-pressure water nozzle 46 is aligned with the middle left side of the bicycle rim body 1 to facilitate the pumping of water from the inside of the water tank 41. The water is then sprayed out under high pressure to wash away the debris concentrated on the front rubber protective sleeve 58, thereby improving the cleanliness of the debris cleaning of the concave structure of the bicycle rim body 1.

[0033] As a further implementation of this solution, one side of the electric telescopic rod 52 and the limiting telescopic rod 53 are fixedly connected to one side of the upper end of the base plate 31. One end of the extension plate 55 is an arc shape and is located inside the bicycle rim body 1. The inner side of the airbag 57 is hollow, and the inner side of the airbag 57 near the extension plate 55 is a through structure. The end of the rubber sheet 56 away from the extension plate 55 is fixed to the inner side of the airbag 57. The top and bottom ends of the rubber sheet 56 are spaced from the top and bottom ends of the airbag 57. The design of the scraping component 5 can adapt to the shape of the concave structure of the bicycle rim body 1, so that the rubber protective sleeve 58 can easily scrape off the debris of the concave structure of the bicycle rim body 1. The rubber protective sleeve 58 plays a role in protecting the airbag 57.

[0034] Workflow: When cleaning debris from the concave structure of the bicycle rim body 1, first fix the bicycle rim body 1 by placing it on top of the base plate 31. Secure the rigid plate 35 with bolts, ensuring one side of the arc-shaped clamp 36 is tightly against the inner side of the bicycle rim body 1. Then, secure another arc-shaped clamp 36 to the inner side of the bicycle rim body 1 and fix the other rigid plate 35. With the bicycle rim body 1 fixed, the hydraulic rod at one end of the drilling device 2 pushes the drilling structure to move, thus achieving the effect of drilling a hole at the right end of the bicycle rim body 1. Then, rotate the bicycle rim body 1, using a servo... The servo motor 32 and turntable 33 drive the bicycle rim body 1 to rotate. After the bicycle rim body 1 is drilled, the electric telescopic rod 52 at the front end is activated to move the movable plate 51. At this time, the limiting telescopic rod 53 extends, which can improve the stability of the movable plate 51 during movement. After the airbag 57 and rubber protective sleeve 58 at the front end are inside the front end of the bicycle rim body 1, the rubber sheet 56 deforms under the pushing action of the extension plate 55, and the airbag 57 and rubber protective sleeve 58 expand. Under the pulling action of the rubber sheet 56, both the upper and lower ends of the rubber protective sleeve 58 expand. When the bicycle rim body 1 expands, the rubber protective sleeve 58 adheres tightly to the concave structure of the rim body 1. As the rim body 1 rotates, the rubber protective sleeve 58 removes debris from the concave structure. Because the rubber protective sleeve 58 is fitted inside the concave structure, it can scrape away debris. After removing debris from one circumference of the rim body 1, some debris concentrates on the left side of the front rubber protective sleeve 58. At this point, the rear electric telescopic rod 52 is activated, pushing the rear airbag 57 and the rubber protective sleeve 58 forward. The deformation of the rubber protective sleeve 58 seals the rear end of the bicycle rim body 1. The water pump 42 is started to draw water from the water tank 41 and enters the high-pressure water nozzle 46 through the connecting arc pipe 43 and the riser pipe 45. The water is then sprayed out in the form of high pressure. After the water comes into contact with the inside of the bicycle rim body 1, the water spreads outwards and enters the concave structure inside the bicycle rim body 1. The water washes the left side of the two rubber protective sleeves 58 respectively, thereby achieving the effect of cleaning the debris on the rubber protective sleeves 58. The combination of the two scraping components 5 can prevent water from contacting the drilling device 2, ensuring the safe use of the drilling device 2.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
