It transmits electricity or information from one place to another. Its basic components include conductor, insulation layer, shielding layer (some cables have) and sheath. Power cable: used to transmit electrical energy, it is the most common type of cable. According to the voltage level, it can be divided into low-voltage power cable (1kV and below), medium-voltage power cable (1kV-35kV), high-voltage power cable (35kV-220kV) and ultra-high-voltage power cable (above 220kV). Power cables of different voltage levels differ in insulation requirements, structural design, etc.

[0003] After the cable laying path is determined, the original length of the cable may not meet the requirements based on the actual measured distance and the pre-designed cable direction. When the cable needs to be cut, the existing cable cutters are often large in size, complex in structure, and heavy in weight.

[0017] Specific workflow: The cutter adopts a compact design and lightweight materials, and has a small overall size and light weight, which is convenient for quick transfer and use between different work locations. It is particularly suitable for outdoor operations and situations where the cable needs to be cut at multiple different locations. Due to its small and light characteristics, the position and angle can be adjusted more flexibly when in use. By placing one end of the cable into the inner side of the main body part 1, the cutting part 3 is opened, and the cable in the main body part 1 is cut by the cutting part 3. At the same time, the cable debris generated in the process of cutting the cable can be collected by opening the collecting part 4; By placing one end of the cable in the main housing 11 and pulling the cable to move in the main housing 11, a support rod 12 is provided on the side of the main housing 11, a roller 13 is rotatably provided on the inner side of the support rod 12, and a ball 15 is provided in a placement plate 14 on the inner wall of the main housing 11. When the cable is pulled and moved in the inner side of the main housing 11, the outer surface of the cable is in contact with the side of the roller 13, thereby converting the contact friction between the cable and the inner side of the main component 1 into rolling friction, thereby avoiding friction damage to the outer surface of the cable caused by the friction force generated when the cable is pulled in the inner side of the main housing 11. When the cable moves to a suitable position inside the main housing 11, the hydraulic cylinder 33 is turned on, and the output end of the hydraulic cylinder 33 drives the cutter 35 to move downward through the connecting shaft 34, so that the cutter 35 continues to pass through the cutting groove 16 downward until it abuts against the limiting groove 19, thereby cutting the cable placed on the placing plate 14. At the same time, when the connecting shaft 34 is driven downward by the output end of the hydraulic cylinder 33, the connecting shaft 34 can drive the connecting rod 36 to drive the positioning plate 37 to disengage from the moving groove 17, so that the positioning plate 37 can squeeze and fix the side of the cable when the cutter 35 cuts the cable, thereby avoiding the cable from being deflected in the main housing 11 when the cable is cut, thereby causing the cable to be cut off and damaged when the cutter 35 cuts off. After the cutter 35 cuts the cable, the output end of the hydraulic cylinder 33 drives the cutter 35 to move upward and reset through the connecting shaft 34. When the cutter 35 continues to move upward, the cutter 35 moves upward through the cutting groove 16, so that the side of the cutter 35 contacts and moves with the scraper 183, thereby avoiding that a large amount of cable debris will remain on the side of the cutter 35 after the cutter 35 cuts the cable. At the same time, when the scraper 183 contacts and cleans the side of the cutter 35, the scraper 183 contacts and moves with the cable debris adhered to the cutter. When the squeezing force between the cable debris on the cutter 35 is greater than the tensile force of the first spring 184 on the contact frame 182, the first spring 184 is squeezed and compressed, so that the first spring 184 pulls the contact frame 182 to move, so that the contact shaft 181 slides inside the cut-off groove 16, so that the contact frame 182 drives the scraper 183 to move away from the cutter 35, thereby avoiding excessive squeezing force between the scraper 183 and the impurities adhering to the cutter 35, which will cause squeezing damage to the cutter 35; When the cutter 35 cuts the cable in the main housing 11, the suction mechanism 42 is turned on, and the suction force generated by the suction mechanism 42 is used to make the connecting plate 46 drive the extrusion mechanism 48 to move downward, and at the same time pull the second spring 47 to move downward, so that the extrusion mechanism 48 is separated from the mesh of the mesh plate 43, so that the cable debris generated when the cable is cut is sucked into the collection housing 41 through the mesh plate 43, and then falls on the baffle 44 for collection; After the cable is cut off, by closing the suction mechanism 42, the connecting plate 46 is driven by the reset of the second spring 47 and driven by the sliding rod 45 to slide upward, so that the connecting plate 46 drives the extrusion rod 481 to move upward, so that the extrusion rod 481 drives the ejector pin 486 through the sliding rod 484 to eject the cable impurities blocked in the mesh of the mesh plate 43, thereby avoiding the cable debris from clogging the mesh of the mesh plate 43 when the cable debris passes through the mesh plate 43 and enters the inner cavity of the collection shell 41 for collection during the cable debris collection work, thereby interfering with the collection of the cable debris during the cable cutting work. At the same time, when the second spring 47 continues to drive the connecting plate 46 to reset upward, the extrusion rod 481 drives the arc plate 488 through the sliding rod 484 to contact and move with the inner wall of the mesh of the mesh plate 43, so that the arc plate 488 contacts the inner wall of the mesh of the mesh The wall is contacted and cleaned, thereby avoiding that after the impurities blocked in the mesh of the mesh plate 43 are cleaned and ejected, some dust and impurities will still remain on the inner wall of the mesh of the mesh plate 43, and then if it is not cleaned for a long time, the mesh of the mesh plate 43 will be blocked. At the same time, when the arc plate 488 is in continuous cleaning contact with the inner wall of the mesh of the mesh plate 43, when the extrusion force between the arc plate 488 and the inner wall of the mesh of the mesh plate 43 is greater than the tensile force of the third spring 487, the third spring 487 drives the circular plate 485 to shrink and move downward, so that the slider 483 moves downward in the groove 482, so that the slider 483 drives the arc plate 488 to move downward through the slide rod 484, thereby avoiding that when the inner wall of the mesh of the mesh is cleaned, the extrusion force between the arc plate 488 and the inner wall of the mesh of the mesh plate 43 is too large, which will cause friction damage to the inner wall of the mesh, thereby causing the mesh aperture to expand.
