Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0057] See also Figure 1-9 One embodiment of the present invention is a device for detecting wear and fatigue of a polymer cable, comprising a pipe 1, a polymer cable 2 being arranged in the pipe 1, and further comprising:

[0058] The moving mechanism 3 is movable in the pipeline 1 and is used to move into the pipeline 1;

[0059] The rotating mechanism 4 is provided on the moving mechanism 3 and is used to rotate the camera installed on the rotating mechanism 4 to move and shoot the polymer cable 2;

[0060] A cleaning mechanism 5 is provided on the moving mechanism 3 and is used to clean dust on the polymer cable 2;

[0061] Wherein, the moving mechanism 3 includes:

[0062] Multiple outer rings 31, every two outer rings 31 are symmetrically connected to form a cylindrical shape;

[0063] Two connecting rings 32 are fixedly connected between the outer rings 31;

[0064] A plurality of inner rings 33 are respectively connected to the inner wall of each outer ring 31;

[0065] A plurality of screw rods 36 and limiting rods 37 are respectively connected between the two outer rings 31, and the fixed outer ring 31 is cylindrical;

[0066] Multiple curved plates 34 are connected to the outer wall of the inner ring 33 through telescopic rods 38, and one side of the telescopic rods 38 is connected to a curved connecting plate, and the telescopic rods 38 are movably connected to the outer wall of the outer ring 31;

[0067] The inner wall of the outer ring 31 is fixedly connected to an electric push rod, and the output end of the electric push rod is connected to the arc-shaped connecting plate to pull the arc-shaped connecting plate to move;

[0068] A plurality of rollers 35 are mounted on the outer side of the arc-shaped plate 34 and move in contact with the inner wall of the pipe 1 .

[0069] The moving mechanism 3 also includes:

[0070] A plurality of arc-shaped extension rods 39 are movably connected in the slide grooves provided on the inner wall of the inner ring 33;

[0071] The arc-shaped limiting rod 391 is movably connected in the slide groove and connected to the arc-shaped extension rod 39;

[0072] Spring 1 392 is movably mounted on the outer wall of the arc-shaped limiting rod 391 , and both ends of spring 1 392 are respectively connected to the slide groove and the arc-shaped extension rod 39 for pushing the arc-shaped extension rod 39 to move.

[0073] The screw rod 36 is threadedly connected between the two outer rings 31 in the vertical direction, and the limiting rod 37 is slidably connected between the outer rings 31 and is located on one side of the screw rod 36 .

[0074] 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 activated 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 direct placement of the detection device 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 rolls on the inner wall of the pipeline 1 through the roller 35 on the arc plate 34. During the inspection, it can be moved in the pipeline 1 to detect the polymer cable 2 at different positions;

[0075] 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 rod 37 are fixed to limit the polymer cable 2 to the inner wall of the inner ring 33. At the same time, the diameter of the polymer cable 2 and the pipe 1 with different diameters are adjusted to achieve targeted adjustment. 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.

[0076] See also Figure 1-9 Based on the above embodiment, in another embodiment of the present invention, the rotating mechanism 4 includes:

[0077] A plurality of arc-shaped rods 41 are fixedly connected to the inner side of the inner ring 33;

[0078] A fixing block 42 is fixedly connected to the outer wall of the arc-shaped rod 41;

[0079] The sliding rod 43 is fixedly connected to the outer wall of the fixed block 42 and has the same curvature as the arc rod 41;

[0080] 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 .

[0081] The rotating mechanism 4 also includes:

[0082] A rotating shaft 48 is mounted on the output end of the motor 47;

[0083] An arcuate groove 46 is formed on the sealing plate between the inner ring 33 and the outer ring 31 . One side of the motor 47 is slidably connected in the arcuate groove 46 via a sliding column, and one side of the rotating shaft 48 is slidably connected in the arcuate groove 46 on the other side.

[0084] 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 by the slider 44 to slide on the slide rod 43, so as to realize 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.

[0085] See also Figure 1-9 On the basis of the above embodiment, in another embodiment of the present invention, the cleaning mechanism 5 includes:

[0086] The 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 a brush.

[0087] The cleaning mechanism 5 also includes:

[0088] The tooth block 51 is mounted on the inner wall of the inner ring 33;

[0089] Gear 49 is fixedly mounted on the outer wall of the rotating shaft 48 and meshes with the gear block 51;

[0090] A connecting block 54 is fixedly connected to one side of the motor 47;

[0091] A movable column 56 is movably connected in the connecting block 54, and the inner wall of the movable column 56 is hollow, and a spring 57 is provided on the inner wall of the movable column 56;

[0092] The push plate 55 is fixedly connected to one end of the movable column 56 and is pushed by the spring 57 to move toward the center of the inner ring 33;

[0095] Scraping rods 53 are fixedly connected to both sides of the outer wall of the arc-shaped push plate 52 and are in contact with the bristles 59. When rotating, the scraping rods 53 are removed from the bristles 59.

[0096] Working principle: During the rotation detection, the arc-shaped push plate 52 will push the drooping polymer cable 2 to prevent the drooping polymer cable from affecting the movement of the camera installed inside the arc-shaped push plate 52. The arc-shaped push plate 52 is transparent, which makes it easier for the camera to shoot the polymer cable 2.

[0097] When the motor 47 rotates, it drives the rotating shaft 48 and the slide column to move in the wavy groove 45. According to the shape of the wavy groove, a shaking stroke is achieved, so that the arc-shaped push plate 52 is rotated to push the polymer cable 2, so as to achieve a flapping 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;

[0098] At the same time, the scraper 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.
