[0001] The invention relates to the technical field of cable surface damage detection equipment, in particular to a cable surface damage detection device. Background Art

[0002] With the development of industrial automation, the application of electricity has penetrated into all aspects of our lives. Cables play an extremely important role in the transmission of electricity. If there are defects on the surface of power cables, it will bring great safety hazards to the safe operation of power cables. In addition, the operating environment is harsh, and maintenance and fault detection are difficult. Therefore, it is necessary to detect high-voltage power cables.

[0010] Furthermore, the linkage mechanism also includes a plurality of extrusion sliders slidably connected to the fixed bent rod, the side wall of the extrusion slider is rotatably connected to the extrusion rod 2, the end of the extrusion rod 2 away from the extrusion slider is rotatably connected to the rotating rod, the middle part of the rotating rod is rotatably connected to the extrusion rod 1, and both ends of the fixed bent rod are sleeved with extrusion springs.

[0013] The present invention has the following beneficial effects: (1) In the present invention, when the traction device drives the cable into the detection tube, the drive motor is started, the output end of the drive motor rotates to drive the output shaft to rotate, the output shaft rotates to drive the gear to rotate, the gear rotates to drive the rotating sleeve on the gear ring to rotate, the rotating sleeve rotates to drive the connecting block inside the cleaning mechanism to rotate, the connecting block rotates to drive the fixed bent rod to rotate, the fixed bent rod rotates to drive the cleaning roller on the cleaning rod to rotate along the outer wall of the cable. By providing the cleaning roller, the cleaning roller is conducive to removing impurities adhering to the outer wall of the cable, thereby preventing the impurities on the outer wall of the cable from affecting the accuracy of the detection of the device.

[0014] (2) According to the present invention, when the cable surface damage detection device is used, the cable to be installed is first placed on the input arc plate of the device. The cable to be installed is pulled into the detection tube through the input arc plate by the traction device under the prior art. When the cable moves to the positioning mechanism, the outer wall of the cable is squeezed by the positioning pulley. The positioning pulley is squeezed by the outer wall of the cable and moves toward the outer wall of the detection tube. The movement of the positioning pulley drives the positioning telescopic rod to contract. At this time, the elastic force of the positioning spring increases. The outer wall of the cable is supported by a plurality of positioning pulleys, which is conducive to the smooth sliding of the cable in the detection tube.

[0015] (3) In the present invention, the outer wall of the cable is squeezed by the positioning pulley, and the positioning pulley is squeezed by the outer wall of the cable and moves toward the outer wall of the detection tube. The movement of the positioning pulley drives the positioning telescopic rod to shrink. The positioning pulley moves upward and drives the push rod on the linkage rod to slide along the fixed ring. The push rod moves and squeezes the squeezing ring. The squeezing ring is squeezed to the right by the push rod. The squeezing ring moves to the right and drives the linkage column to slide to the right along the connecting block 2. At this time, the linkage column drives the rotating rod on the squeezing rod 1 to move to both sides of the linkage column. The rotating rod drives the squeezing slider on the squeezing rod 2 to squeeze the squeezing spring along the fixed bent rod. At this time, the squeezing spring is subjected to an increased squeezing elastic force. The squeezing spring elastic force increases. Since the squeezing spring is squeezed by the sliding ring, the squeezing force of the squeezing spring on the sliding ring increases. At this time, the squeezing force of the sliding ring on the cleaning roller on the cleaning rod increases. The squeezing force of the cleaning roller on the surface of the cable increases, and the friction force of the cleaning roller on the surface of the cable increases. Such a configuration is conducive to increasing the friction force of the cleaning roller on the surface of the cable, thereby enhancing the cleaning effect of the cleaning roller on the cable.

[0016] (4) The present invention sets a detection mechanism. When the positioning pulley is squeezed by the outer wall of the cable and moves toward the outer wall of the detection tube, the positioning pulley moves and drives the positioning telescopic rod to contract. The positioning pulley moves upward and drives the push rod on the linkage rod to slide along the fixed ring. The push rod moves and drives the push ring on the connecting column one to move. The push ring moves to the right and drives the slider on the connecting column two to slide to the right along the slide groove. The slider moves to the right and drives the detection telescopic rod at one end of the detection connecting rod to move toward the cable surface. At this time, the detection telescopic rod drives the detection arc plate to be close to the cable surface. When the detection arc plate is close to the cable surface, the detection telescopic rod squeezes the detection spring, causing the detection spring to contract. The detection spring contraction elastic force increases. The increase in the detection spring elastic force increases the squeezing force of the detection arc plate on the cable surface. This arrangement is conducive to the detection arc plate to detect defects on the cable surface. On the other hand, the side wall of the detection arc plate is conducive to scraping off impurities missed by the cleaning mechanism, thereby improving the fault tolerance rate of the device.
