Description

Technical Field

[0001] The present invention relates to the technical field of electric power maintenance, and in particular to a cable power leakage detection device for electric power maintenance. Background Art

[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 the insulation material. Cables are widely used in power transmission, information communication, control systems and other fields to achieve efficient transmission of electric energy and signals. When the insulation layer of the cable is accidentally damaged, it will cause power leakage. In order to detect the specific location of the damage and facilitate repair, it is necessary to use cable power leakage detection equipment for detection. During the detection, in order to ensure the accuracy of the test results, it is necessary to effectively remove the debris on its surface 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 fixing plate, a connecting plate, a damping pad, a U-shaped hinge, an outer fixing plate, an L-shaped hinge, a small support spring, a triangular clip, and a petal threaded member. The cutting knife is fixedly connected to the scraper knife, the scraper knife is fixedly connected to the tension spring, the tension spring is fixedly connected to the connecting plate, the connecting plate is fixedly connected to the damping pad, the scraper knife is hinged to the strip fixing plate, the strip fixing plate is fixedly connected to the connecting plate, the connecting plate is hinged to the U-shaped hinge, the U-shaped hinge is contact-connected to the petal threaded member, the petal threaded member is threadedly connected to the outer fixing plate, the outer fixing plate is fixedly connected to the L-shaped hinge, the L-shaped hinge is fixedly connected to the small support spring, the small support spring is fixedly connected to the triangular clip, the triangular clip is hinged to the L-shaped hinge, and the triangular clip is connected to the petal threaded member through a groove.

[0004] When the cable power leakage detection device in the above application is in use, the scraper knife is pulled by the tension spring to scrape off the impurities on the cable surface. The scraper knife is brought into contact with the cable by the tension spring. However, when scraping thicker cables, the tension spring with a larger degree of compression can easily cause the scraper knife to have excessive pressure contact with the cable surface, which can easily cause the scraper knife to cause cutting damage to the cable surface, affecting the quality of the cable. The spring is also prone to certain plastic deformation after long-term use.

[0045] When the whole device moves on the cable, the metal scraper blade 301 inside the scraper seat 6 moves along the cable and the blade end of the metal scraper blade 301 contacts the cable surface. The cable surface is scraped by multiple moving metal scraper blades 301 inside the scraper seat 6. The multiple metal scraper blades 301 can completely scrape and clean the impurities on the cable surface. When the metal scraper blade 301 contacts the cable surface, the metal scraper blade 301 moves and scrapes the impurities on the cable surface.
