[0023] Working principle: When inspecting the outer wall of the polymer cable 2, the cable inside the pipeline needs to be inspected. At this time, the detection device is placed in the pipeline 1. At this time, the electric push rod on the detection device is started to extend, driving the arc-shaped connecting plate to move, thereby contracting and driving the telescopic rod 38 to move, so as to facilitate the detection device to be directly placed in the pipeline 1. Then, by contracting the electric push rod, the arc-shaped connecting plate is driven to move, and then the telescopic rod 38 is driven to move outward, so that the detection device is rolled on the inner wall of the pipeline 1 through the roller 35 on the arc plate 34, so that during the inspection, it can be moved in the pipeline 1 to detect the polymer cable 2 at different positions; Then, by loosening the screws 36 on both sides, the polymer cable 2 is directly stuck in the inner ring 33, and then the inner ring 33 and the outer ring 31 on the upper and lower sides are brought close to each other, and then the screws 36 and the limit rods 37 are fixed to limit the polymer cable 2 to the inner wall of the inner ring 33, and at the same time, the diameters of the polymer cables 2 and the pipes 1 with different diameters are adjusted to achieve targeted adjustment, and at the same time, the spring 1 392 is used to push the arc limit rod 391 and the arc extension rod 39 outward to continue to close the area inside the inner ring 33 to prevent the polymer cable 2 from detaching from the inner ring 33, thereby improving the detection efficiency of the polymer cable 2, and at the same time, the camera is moved to shoot the polymer cable 2, so as to observe the wear of the polymer cable 2 inside the pipe.

[0024] See also Figure 1-9 Based on the above embodiment, in another embodiment of the present invention, the rotating mechanism 4 includes: A plurality of arc-shaped rods 41 are respectively fixedly connected to the inner side of the inner ring 33; A fixing block 42, fixedly connected to the outer wall of the arc-shaped rod 41; The sliding rod 43 is fixedly connected to the outer wall of the fixing block 42 and has the same curvature as the arc rod 41; The slider 44 is slidably connected to the outer wall of the slide rod 43 , and a motor 47 is fixedly connected to the other side of the outer wall thereof, and the camera is arranged on one side of the motor 47 .

[0026] Working principle: When performing stage detection, the motor 47 works to drive the rotating shaft 48 to rotate, and then drives the gear to rotate, and rotates on the tooth block 51, so that the motor 47 is driven to slide on the slide bar 43 through the slider 44, so that during the stage detection, the polymer cable 2 located on the inner ring 33 is surrounded by detection, so that the camera is rotated around the outer wall of the polymer cable 2, and the polymer cable 2 is photographed to improve the detection effect.

[0027] See also Figure 1-9 Based on the above embodiment, in another embodiment of the present invention, the cleaning mechanism 5 includes: The brush bristles 59 are mounted on the inner wall of the inner ring 33 and are used to remove dust from the outer wall of the polymer cable 2 by moving the brush.

The arc-shaped push plate 52 is transparent, which is convenient for the camera to shoot the polymer cable 2. When the motor 47 rotates, the rotating shaft 48 and the slide column are driven to move in the wavy groove 45, and a shaking stroke is achieved according to the shape of the wavy groove, so that the arc-shaped push plate 52 is rotated to push the polymer cable 2, so as to achieve a slapping effect on the polymer cable 2, thereby preventing dust on the outer wall of the polymer cable 2 from affecting the shooting effect of the polymer cable 2; At the same time, the scraper rod 53 on the arc-shaped push plate 52 that rotates and shakes along the circumference is used to brush the polymer cable 2 to improve the cleaning effect of the polymer cable 2, thereby improving the shooting effect of the outer wall of the polymer cable 2.
