Cable damage detection device

Abstract

The invention discloses a cable damage detection device which comprises a main frame, a supporting groove, an inner gear ring, a first supporting cylinder, a first supporting rod, a turbine, a first gear, a second supporting cylinder, a roller brush, a worm, a first bevel gear, a first supporting shaft, a first volute, a second volute, a turbofan, a transmission part and a marking part. A plurality of horizontal supporting grooves are formed in the left portion and the right portion of the main frame in a penetrating mode respectively, a plurality of inner gear rings are fixed to the left portion and the right portion of the main frame respectively, the inner gear rings are located on the left outer edge and the right outer edge of the supporting grooves respectively, and the axes of the inner gear rings and the axes of the supporting grooves are coaxial. According to the cable detection device, the functions of automatic cleaning, automatic detection and automatic marking are achieved while a cable is dragged, the detection efficiency is greatly improved, roller brushes on the left portion and the right portion of a main frame can continuously rotate in the opposite directions through rotation of a gear motor, and the detection efficiency is greatly improved. And meanwhile, the turbofans can rotate in opposite directions relative to the first volute and the second volute, and the upper dragging shaft and the lower dragging shaft can rotate in opposite directions.

Description

technical field [0001] The invention relates to the field of cable detection, in particular to a cable damage detection device. Background technique [0002] In order to achieve long-distance power transmission, it is often necessary to erect various cables, and these cables are affected by various environmental factors and human factors after long-term use (such as light, temperature, humidity, external force and radiation, etc.) , will have a certain negative impact on the life of the cable. An important indicator to measure the life of the cable is the insulation performance of its insulator. For the cable, once the insulator is damaged, its own insulation performance will be greatly reduced, and the poor insulation performance When the cable is in use, it is prone to accidents such as leakage and short circuit, which seriously affect the safety of electricity use. Therefore, after a long-term use of the cable, it is necessary to regularly test its insulation performance,...

[0002] In order to achieve long-distance power transmission, it is often necessary to erect various cables, and these cables are affected by various environmental factors and human factors after long-term use (such as light, temperature, humidity, external force and radiation, etc.) , will have a certain negative impact on the life of the cable. An important indicator to measure the life of the cable is the insulation performance of its insulator. For the cable, once the insulator is damaged, its own insulation performance will be greatly reduced, and the poor insulation performance When the cable is in use, it is prone to accidents such as leakage and short circuit, which seriously affect the safety of electricity use. Therefore, after a long-term use of the cable, it is necessary to regularly test its insulation performance, so as to judge whether its insulation performance can meet the use requirements. , while the traditional cable damage detection device cannot significantly mark the damage when detecting the cable, it still needs manual secondary treatment, and the cable often needs to use cleaning equipment to clean the outer wall of the cable before detection, and the sequence It will consume a certain amount of time in the process, so the efficiency of cable detection will be reduced, highlighting its shortcomings
