Problems solved by technology

[0003] The appearance inspection of high-voltage power transmission cables has many contents, including thickness inspection, diameter inspection, etc. In addition, it is necessary to ensure that the surface of the cable has no crack defects. Sometimes, the cable needs to be tested for a week. At present, more methods are used for visual inspection and infrared detectors. , most of the detectors are complex in structure, and also need to flip the cable, which is inconvenient to use

Abstract

The invention relates to the technical field of cable detection, and discloses a high-voltage transmission cable appearance detection device. The device comprises a detection base and a sliding base,a gas storage chamber is fixedly connected into the detection base, a piston is movably inserted into the detection base, the outer side of a first connecting shaft is movably sleeved with a pulley, the outer side of a second connecting shaft is movably sleeved with a top plate, a probe is movably inserted into the detection base, an indicator lamp is fixedly installed on the outer side of the detection base, and a button switch is fixedly installed in the detection base. The detection base and the sliding base sleeve the outer side of a cable main body and move leftwards, the top plate is driven to continuously impact the piston in order to inflate the gas storage chamber, the gas slowly flows out through a guide groove, and when cracks occur on the surface of the cable main body, a gap between the detection base and the cable main body is enlarged, the pressure of the gas on the probe is reduced, the probe falls down, the indicator lamp is lightened, whether the crack exists or not can be judged by observing the condition of the indicator lamp, and the operation is simple and convenient.

Description

technical field [0001] The invention relates to the technical field of cable detection, in particular to a high-voltage transmission cable appearance detection device. Background technique [0002] In high-voltage power transmission, the importance of cables is unquestionable. The quality of cables is directly related to the normal transmission of power. Due to the particularity of high-voltage power, the quality of cables is also related to the surrounding environment and personal health Safety, therefore, in the process of manufacturing and using the cable, it must be strictly tested, and it can continue to be used after passing the test. [0003] The appearance inspection of high-voltage power transmission cables has many contents, including thickness inspection, diameter inspection, etc. In addition, it is necessary to ensure that the surface of the cable has no crack defects. Sometimes, the cable needs to be tested for a week. At present, more methods are used for visu...
