and step 3: the image acquisition module of the detection mechanism consists of a plurality of CCD cameras and two groups of annular light sources, the two groups of annular light sources form a uniform bright field by adopting the principle of machine vision imaging, each CCD camera can respectively cover an area which exceeds 1/6 of a cable to carry out 360-degree surrounding scanning on the cable, and can acquire uniform and clear images;
and 4, step 4: the device comprises an encoder, a plurality of CCD cameras, an image acquisition module, a processor, a flaw detection module, an audible and visual alarm module, a data acquisition module and a data storage module, wherein the encoder acquires a moving speed signal of a cable so as to detect the moving speed signal, the cable passes through a scanning area of the CCD cameras in the moving process, the CCD cameras synchronously shoot according to the moving speed signal acquired by the encoder, then the acquired image is transmitted to the image acquisition module, and the image is analyzed and processed by the processor, so that the flaw is effectively found and judged to be bad, and meanwhile, the audible and visual alarm module automatically gives an audible and visual alarm to remind workers on site;
and 5: when the detection device of the detection mechanism detects the insulation defect of the cable, the defect part of the cable can be marked through the positioner, so that the cable can be conveniently found by personnel.
