[0053] The rotating assembly includes: a square plate 40, a second rotating shaft 41, a third box body 42, a third servo motor 43, a movable rod 44, and a connecting rod 45;

[0054] Both ends of the top of one group of square plates 40 are fixedly installed with square plates 40. The second rotating shaft 41 is rotatably connected between the two square plates 40 through bearings. The movable rod 44 is fixedly installed on the second rotating shaft 41.

[0055] It further includes: a cleaning component for scraping impurities on the drain pipe 10, and the cleaning component is arranged in the drain pipe 10.

[0056] The cleaning component includes: a second box 50, a second electric push rod 51, a third support plate 52, a blade 53, and a telescopic rod 54;

[0057] A plurality of second boxes 50 are fixedly installed on the inner surface of the C-shaped plate 20. The second electric push rod 51 is fixedly installed in the second box 50. The push rod of the second electric push rod 51 is fixedly installed with a third support plate 52. The blade 53 is fixedly installed on one side of the third support plate 52. The telescopic rod 54 is fixedly installed between the C-shaped plate 20 and the third support plate 52.

[0058] In specific use, the operation steps of those skilled in the art are as follows:

[0059] S1: First, the drain pipe 10 is placed in the C-shaped plate 20 through the opening of the C-shaped plate 20, and then, the first support plate 32 is moved toward the drain pipe 10 through the first electric push rod 31. When the first support plate 32 moves, the second support plate 35 is moved toward the drain pipe 10. When the second support plate 35 moves, the roller 38 is moved toward the drain pipe 10 until the roller 38 is in close contact with the surface of the drain pipe 10 through the anti-slip ring 39. At this time, the moving direction of the roller 38 is toward the axial direction of the drain pipe 10. After that, the first rotating shaft 37 is rotated by the second servo motor 392. When the first rotating shaft 37 rotates, the roller 38 is driven to rotate. When the roller 38 rotates, the C-shaped plate 20 is moved along the axial direction of the drain pipe 10;

[0060] S2: If an obstacle appears during the movement, the second support plate 35 will be rotated by the first servo motor 34. When the second support plate 35 rotates, the roller 38 will be driven to rotate at an angle of 90°, so that the moving direction of the roller 38 is toward the radial direction of the drain pipe 10. At this time, the first rotating shaft 37 will be rotated by the second servo motor 392. When the first rotating shaft 37 rotates, the roller 38 will be driven to rotate. When the roller 38 rotates, the C-shaped plate 20 will be moved along the radial direction of the drain pipe 10 until the obstacle is aligned with the C-shaped plate. After the opening of the drain pipe 20 is aligned, the second support plate 35 is rotated by the first servo motor 34. When the second support plate 35 rotates, the roller 38 is driven to rotate. The rotation angle is 90 degrees, so that the moving direction of the roller 38 is toward the axial direction of the drain pipe 10. Then, the first rotating shaft 37 is rotated by the second servo motor 392. When the first rotating shaft 37 rotates, the roller 38 is driven to rotate. When the roller 38 rotates, the C-shaped plate 20 is moved along the axial direction of the drain pipe 10. At this time, the C-shaped plate 20 can pass through the obstacle.

[0061] S3: During the movement of the C-shaped plate 20, the surface of the drain pipe 10 is photographed by the camera 21 for detection;

[0062] S4: When it is detected that there are impurities on the surface of the drain pipe 10 that affect the detection, the C-shaped plate 20 is moved along the axial direction of the drain pipe 10 until the impurities are located on the upper and lower sides of the blade 53. After that, the C-shaped plate 20 is moved along the radial direction of the drain pipe 10 so that the blade 53 can rotate with the drain pipe 10 as the center point. When the blade 53 rotates, the impurities on the drain pipe 10 are scraped off;

[0063] S5: When encountering another set of perpendicular drain pipes, the opening of the C-shaped plate 20 will first face downward or upward (depending on whether the other set of drain pipes is below or above the drain pipe 10). Then, the internal moving components of the C-shaped plate 20 facing the drain pipe (hereinafter referred to as C-shaped plate A) will be restored to their original positions. After that, the second rotating shaft 41 will be rotated by the third servo motor 43. When the second rotating shaft 41 rotates, the movable rod 44 will be driven to rotate. When the movable rod 44 rotates, the C-shaped plate A will be driven to rotate by 90° so that the opening of the C-shaped plate A faces the other set of drain pipes. Finally, the C-shaped plate A will be moved by the moving components on another set of C-shaped plates 20 (hereinafter referred to as C-shaped plate B) until the other set of drain pipes is located in the C-shaped plate A and clamped by the rollers 38. At this time, the internal moving components of the C-shaped plate B will be restored to their original positions, and the C-shaped plate A will be moved on the other set of drain pipes. During this process, the other set of drain pipes will be located in the C-shaped plate B and clamped by the rollers 38. Thus, the pipeline robot completes the movement of perpendicular pipes.

[0064] Although the present invention has been described above with reference to the embodiments, various improvements can be made to it and its components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the disclosed embodiments of the present invention can be combined with each other in any way.
