Description

Technical Field

[0001] The present invention relates to the technical field of cable detection, and particularly to a cable core break detection device. Background Art

[0002] During the use of cables, the phenomenon of core breakage is inevitable. Core breakage refers to the partial fracture of the wire cores inside the cable, which will affect the transmission performance of the cable. For cables that have been laid, when a core breakage occurs, it is usually necessary to first locate the core breakage position, then cut the cable at the core breakage position, and then replace it with a new cable section for repair. Therefore, how to quickly determine the core breakage position of the cable is the key to quickly solving the cable core breakage problem.

[0003] Traditional core breakage detection methods usually rely on electrical signals, such as resistance, induced voltage, etc. However, if there are contaminants such as dirt, oxide layers, and oil stains on the cable surface, the contact between the detection probe and the cable may be poor, resulting in signal distortion, and thus problems such as misjudgment and missed judgment may occur. To improve the detection accuracy, it is often necessary to manually clean the cable surface before detection. However, manual cleaning is not only time-consuming and laborious, but also increases the complexity of the detection process. Especially in long-distance or complex environments, the efficiency is low and it is difficult to ensure consistency.

[0004] Therefore, we propose a cable core break detection device. Summary of the Invention

[0045] Specifically, the cleaning mechanism further includes a scraping plate 44. Mounting plates 41 are arranged in an annular array around the inner wall of the cleaning sleeve 3.

Conical gears 31 are connected to the adjacent ends of the synchronous shaft 30 and the driven shaft 29, and the conical gears 31 mesh with each other;

[0050] When the device moves along the cable, the abrasive belt 6 rotates through the rotating cylinder 27 due to the frictional resistance. The rotating cylinder 27 rotates accordingly and at the same time drives the pulley 28 to rotate. The rotation of the pulley 28 drives the transmission belt 19 to move. The movement of the transmission belt 19 drives the driven shaft 29 to rotate. The driven shaft 29 drives the synchronous shaft 30 to rotate via the conical gear 31. The rotation of the synchronous shaft 30 drives the synchronous belt 33 to move. The movement of the synchronous belt 33 drives the transmission shaft 25 to rotate. The transmission shaft 25 drives the external gear ring 24 to rotate via the transmission gear 26. The external gear ring 24 drives the cleaning sleeve 3 to rotate. The cleaning mechanism moves synchronously with the grinding mechanism without an additional power source and runs passively as the cable broken core detection device moves forward;

[0051] Specifically, the transmission mechanism further includes a tensioning wheel 20. The tensioning wheel 20 is arranged inside the connecting member 2 for tensioning the transmission belt 19.
