Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power maintenance, in particular to a cable power leakage detection device for power maintenance. BACKGROUND

[0002] Cable is an important electrical transmission medium, mainly composed of conductor, insulation layer, shielding layer and sheath. It takes the wire as the core and ensures the stability and safety of current transmission by wrapping insulation materials. Cable is widely used in power transmission, information communication, control system and other fields to realize efficient transmission of electric energy and signal. When the insulation layer of the cable is accidentally damaged, it will cause power leakage. In order to detect the specific position of the damage for repair, cable power leakage detection equipment needs to be used for detection. In order to ensure the accuracy of the detection result, the surface impurities need to be effectively removed first.

[0003] For example, Chinese patent publication No. CN110244162B discloses a power grid cable power leakage detection device, which includes a fixing and cleaning mechanism. The fixing and cleaning mechanism includes a cutting knife, a scraper knife, a tension spring, a strip-shaped fixing plate, a connecting plate, a damping pad, a U-shaped hinge, an outer fixing plate, an L-shaped hinge, a small supporting spring, a triangular clamping piece and a petal-shaped threaded piece. The cutting knife is fixedly connected with the scraper knife. The scraper knife is fixedly connected with the tension spring. The tension spring is fixedly connected with the connecting plate. The connecting plate is fixedly connected with the damping pad. The scraper knife is hingedly connected with the strip-shaped fixing plate. The strip-shaped fixing plate is fixedly connected with the connecting plate. The connecting plate is hingedly connected with the U-shaped hinge. The U-shaped hinge is in contact connection with the petal-shaped threaded piece. The petal-shaped threaded piece is in threaded connection with the outer fixing plate. The outer fixing plate is fixedly connected with the L-shaped hinge. The L-shaped hinge is fixedly connected with the small supporting spring. The small supporting spring is fixedly connected with the triangular clamping piece. The triangular clamping piece is hingedly connected with the L-shaped hinge. The triangular clamping piece is connected with the petal-shaped threaded piece through a groove.

[0004] The cable power leakage detection device in the above-mentioned application pulls the scraper knife to scrape off the impurities on the surface of the cable by means of the tension spring. The scraper knife contacts the cable by relying on the tension spring. However, when the scraper knife is used to scrape off the cable with a larger diameter, the tension spring with a larger compression degree is likely to cause the scraper knife to have an excessive pressure contact with the surface of the cable, which is likely to cause the scraper knife to cut and damage the surface of the cable, affecting the quality of the cable. Moreover, the spring is likely to have plastic deformation after long-time use. In addition, the scraper knife is in dry friction contact with the cable, which affects the impurity removal effect and is likely to cause the scraper knife to be worn out too quickly.

[0005] Therefore, it is necessary to provide a cable power leakage detection device for power maintenance to solve the above-mentioned technical problems. SUMMARY

[0048] In summary: the mobile assembly 1 drives the overall device to move along the cable, and has the ability to walk on the cable. During the movement of the overall device on the cable, the scraping assembly 3 is arranged to scrape the surface of the cable, thereby effectively scraping and cleaning the dirt adhering to the surface of the cable, avoiding the problem of affecting the detection accuracy due to the attachment of dirt on the surface of the cable, and effectively improving the detection accuracy. During the scraping and cleaning of the dirt on the surface of the cable by the scraping assembly 3, the scraping assembly 3 is pushed by the resistance to extrude the cleaning liquid onto the scraping assembly 3, so that the scraping assembly 3 has a certain humidity. The cleaning liquid dissolves the oil stains and other related pollutants on the surface of the cable, making it easier for the scraping assembly 3 to scrape off the dirt adhering to the surface of the cable, effectively improving the scraping and cleaning efficiency and cleaning effect of the scraping assembly 3 on the cable. When detecting and processing different specifications of cables, the pressure adjusting assembly 2 can adjust the extension amount of multiple mobile assemblies 1, so that the mobile assembly 1 can press against the surface of the cable with different diameters, allowing the mobile assembly 1 to move and walk on cables with different diameters. At the same time, the same adjusting assembly 4 is arranged to adjust the mobile assembly 1 and the scraping assembly 3 at the same time, so that the scraping assembly 3 can clean the cables with different diameters, thereby adapting to cables with different diameters, effectively improving the overall application range. Compared with the existing technology, the scraping assembly 3 is pressed by the spring and other elastic members, so that the scraping assembly 3 has a relatively small pressing force on the surface of the cable with different diameters, avoiding the problem of easily damaging the cable due to excessive pressing force of the scraping assembly 3 on the surface of the cable, and improving the protection of the cable.
