Problems solved by technology

[0002] The outside of the cable is usually wrapped with an insulating layer. During actual use, the cable is easily damaged by the external environment and causes damage to the insulating layer, which will cause electrical safety accidents. Therefore, regular or real-time inspection of the cable is required
The cable damage inspection technology in the prior art usually uses unmanned aerial vehicle inspection or manual inspection, which not only has low inspection efficiency, but also has large inspection errors.

Abstract

The invention discloses a cable damage detection device. The cable damage detection device comprises a shell, a displacement mechanism, a detection mechanism and an adjusting mechanism. The displacement mechanism is arranged on the shell and used for driving the shell to move in the length direction of the cable. The detection mechanism is arranged on the shell and can be arranged on the cable in a sleeving mode, a gap is formed between the inner circumferential surface of the detection mechanism and the outer circumferential surface of the cable, in the radial direction of the cable, the difference value between the inner diameter of the detection mechanism and the outer diameter of the normal cable is a constant value, and the detection mechanism is used for detecting the distance between the inner circumferential surface of the detection mechanism and the outer circumferential surface of the cable. And the adjusting mechanism is arranged on the shell and is used for adjusting the distance between the shell and the cable so that the central axis of the detection mechanism and the central axis of the cable are kept coincident. The cable damage detection device can improve the detection efficiency and the detection reliability of the cable.

Description

technical field [0001] The invention relates to the technical field of detection devices, in particular to a cable damage detection device. Background technique [0002] The outside of the cable is usually wrapped with an insulating layer. During actual use, the cable is easily damaged by the external environment and causes damage to the insulating layer, which will cause electrical safety accidents. Therefore, regular or real-time inspections of the cable are required. The cable damage inspection technology in the prior art usually uses unmanned aerial vehicle inspection or manual inspection, which not only has low inspection efficiency, but also has large inspection errors. [0003] Therefore, there is an urgent need for a cable damage detection device that can improve the detection efficiency and reliability of the cable. Contents of the invention [0004] The object of the present invention is to provide a cable damage detection device, which can improve the detection...
