[0032] As a preferred embodiment, the motor 405 is used to drive the pipe conveying roller 403 to rotate around its axis, wherein the output end of the two groups of motors 405 rotates to control the relative rotation of the two groups of pipe conveying rollers 403, and the extension end of the first electric push rod 404 is connected to the moving frame 402 through the fixed stake 401; further, when the pipe is placed between the two groups of pipe conveying rollers 403 rotating relative to each other, the pipe is subjected to friction force from the opposite directions on both sides, so that the pipe can move smoothly along the pipe channel 3 in the set direction, and the first electric push rod 404 can accurately control the position of the moving frame 402. Since the pipe conveying roller 403 is installed on the moving frame 402, the distance between the pipe conveying rollers 403 can be adjusted by the extension and retraction of the first electric push rod 404 to adapt to pipes of different diameters.

[0033] As a preferred embodiment, the moving frame 402 moves with the first electric push rod 404, so that the moving frame 402 and the pipe conveying roller 403 linked thereto move linearly along the surface of the sliding groove 2; further, the moving frame 402 can drive the pipe conveying roller 403 to move stably along the sliding groove 2, and when the two groups of motors 405 control the two groups of pipe conveying rollers 403 to rotate relative to each other, the pipe will be subjected to uniform friction force from both sides.

[0036] Subsequently, the detected pipe continues to move along the pipe channel 3, when the pipe moves under the gantry 11, the water pump 14 starts to work, the water pump 14 extracts the cleaning water from the water storage tank 15 through the water suction pipe 16, and then delivers the water to the upper end of the two groups of water delivery mechanism 12 through the water delivery pipe 13. After the water is evenly distributed in the water delivery mechanism 12, it is sprayed through a plurality of groups of cleaning nozzles 121 arranged in equidistant interval mode. These cleaning nozzles 121 are arranged in a straight line, which can impact the pipe surface in all directions, so that the water sprayed on the pipe surface covers a more regular range, avoids the occurrence of local over-washing or dead angle of cleaning, effectively removes the dust and coupling agent on the pipe surface, and the waste water after cleaning flows down along the pipe surface. The cleaned pipe moves to the water draining rack 10 between the two groups of extension columns 9, the surface of the water draining rack 10 is in the form of stainless steel wire mesh, the water on the pipe surface can quickly drip through the mesh, under the action of gravity, the waste water flows into the water collecting tank 17 below the water draining rack 10 for collection, the water collecting tank 17 collects the waste water for treatment, the height of the water draining rack 10 is lower than the arc surface of the pipe channel 3, the height difference makes the pipe not be blocked when moving from the pipe channel 3 to the water draining rack 10, when the waste water in the water collecting tank 17 needs to be treated, the liquid is connected to the external pipeline through the drain outlet 18 on the right side of the water collecting tank 17, and is safely delivered to the designated place according to the external pipeline specification.
