Problems solved by technology

The cable works under high pressure and high temperature for a long time, which is easy to cause physical and chemical changes, and if it develops to a certain extent, it will cause damage to the insulation layer, which will cause accidents.
The current cable detection mainly relies on manual detection of preventive or maintenance nature, and the efficiency of manual detection is low

Embodiment Construction

[0024] Attached below Figure 1-2 The present invention is further illustrated with specific examples. This embodiment mainly exemplifies the detection method of cables. It is worth noting that this embodiment can also be applied to pipeline detection, and the detection method of the cable 1 to be tested in this embodiment is consistent with that of pipelines.

[0025] Such as figure 1 As shown, a detection device based on image recognition for the cable insulation layer and the outer layer of the pipeline includes:

[0026] The shell seat is set as a structure that penetrates front and back, and accommodates the cable 1 to be tested to pass through it;

[0027] A plurality of cameras 7 for photographing the outer wall of the cable 1 to be tested, all the cameras 7 are installed inside the housing, and are evenly distributed around the axis of the cable 1 to be tested, and there is a gap between the cameras 7 and the outer wall of the cable 1 to be tested;

[0028] A plural...

Abstract

The invention relates to a cable insulation layer and pipeline outer layer detection device based on image recognition in the field of cable safety detection, and the device comprises a housing seat which allows a cable or a pipeline to movably pass through; a plurality of cameras installed in the housing seat and evenly distributed around the axis of the cable or the pipeline, wherein gaps are reserved between the cameras and the outer side wall of the cable or the pipeline; a plurality of trundle motors uniformly distributed around the axis of the cable or the pipeline and mounted in the housing seat, wherein the output end of each trundle motor is provided with a trundle rolling on the outer side wall of the cable or the pipeline. During detection, trundles are driven to roll on the outer side wall of a cable or a pipeline through the trundle motors, so that the whole device moves in the length direction of the cable or the pipeline, the outer side wall of the cable or the pipelineis shot through the cameras, and the quality defect of the outer side wall of the cable or the pipeline can be automatically detected.

Description

technical field [0001] The invention relates to the field of cable safety detection, in particular to a detection device for a cable insulation layer and an outer layer of a pipe. Background technique [0002] Cables are an important part of the power system and the basis for ensuring the reliability of power supply. Cables work under high pressure and high temperature for a long time, which is easy to cause physical and chemical changes, and if it develops to a certain extent, the insulation layer will be damaged, which will cause accidents. The current cable testing mainly relies on manual testing for preventive or maintenance purposes, and the efficiency of manual testing is low. Contents of the invention [0003] The purpose of the present invention is to provide a detection device based on image recognition for the cable insulation layer and the outer layer of the pipe, which can automatically complete the detection of the outer wall of the cable or pipe, and the det...
