The performance of adhesives directly affects the quality of cable repair. Some adhesives may not be able to maintain a stable bonding effect in harsh on-site environments, resulting in water seepage, leakage and other problems in the repaired cables. The existing cable repair process is too complicated and the repair effect is not ideal. Summary of the invention

Through the cutting action of the first stab, the cable sheath is evenly peeled off, forming a flat and clean bonding surface. Such a bonding surface is more conducive to the heating and bonding of the heating component, thereby improving the bonding strength and sealing. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] See also Figure 1 , which is a schematic diagram of a three-dimensional structure of the present invention; the present application optimizes and improves a substation cable damage rapid repair device in the prior art. Compared with the traditional pulley design, the roller can support and transmit the cable more stably due to its larger contact area and better friction, reducing the sliding and shaking of the cable during the repair process. This directly improves the stability and efficiency of the repair process. The magnets embedded between the two rollers change the angle between the rollers by adjusting the arrangement or strength of the magnets. This flexibility allows the device to adapt to cables of different diameters and degrees of curvature without the need for frequent replacement or adjustment of tools, thereby improving work efficiency. The first stab will perform a second cut on the opening of the initial cut, further trimming the edge of the opening to make the opening smoother. This back and forth cutting action helps to remove burrs and irregular parts, providing a better attachment surface for the adhesive material. The flat and smooth opening surface is conducive to the adhesion of the heating device, thereby enhancing the bonding effect. Example 1

The output end of the motor 140 is rotatably connected to a displacement frame 150; The displacement rack 150 is a cylindrical body, and there are two displacement racks 150; A heating plate 160 is fixedly connected to one side of the displacement frame 150 away from the output end of the motor 140; The heating plate 160 is a rectangular body, and has two grooves symmetrically arranged on both sides of the heating plate 160.

[0013] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages: The two rollers 410 allow the cable to be subjected to uniform extrusion during the repair process, which helps the adhesive material of the outer or inner layer of the cable to fit better and improve the repair quality. The rotation of the roller 410 can also drive the cable to move forward smoothly, reduce the complexity of manual operation, and improve the repair speed. Due to the principle that like poles repel each other and opposite poles attract each other, the magnet 411 in the middle of the roller 410 allows the angle between the two rollers 410 to be adjusted. By adjusting the angle, it can be adapted according to cables of different diameters or shapes, ensuring that the cable can fit tightly between the rollers 410 during the repair process, further improving the bonding effect and improving work efficiency. The uniform extrusion force ensures that the heating component 100 can evenly heat the damaged part of the cable, avoiding the problem of poor bonding caused by uneven extrusion force, thereby improving the repair quality and efficiency. The rotation of the roller 410 and the angle adjustment function of the magnet 411 make the repair process more automated, reduce the need for manual intervention, and improve the repair speed. It reduces the errors that may be caused by manual operation, uneven extrusion force, improper angle adjustment, and other problems, thereby improving the repair quality and stability. Example 2

[0014] In order to further improve the applicability and convenience of the use of the substation cable damage quick repair device of the present application, the embodiment of the present application has been optimized and improved on the outside of the drum, specifically: like Figure 5 As shown, the extrusion assembly 400 further includes a first thorn, and the first thorn 420 is fixedly connected to the width direction of the roller 410; There are at least eight first thorns 420 , and each of the first thorns 420 is an isosceles triangle.

[0015] During the cable repair process, the initial scoring is performed by a blade to preliminarily open the damaged portion of the cable. However, due to factors such as the cable material and scoring conditions, the opening of the initial scoring may not be smooth enough or have burrs, which affects the subsequent bonding effect. In order to make up for this deficiency, a first thorn 420 is provided on the outside of the roller 410. When the cable passes through the roller 410 of the extrusion assembly 400, the first thorn 420 will perform a secondary scoring on the opening of the initial scoring, further trimming the edge of the opening to make the opening smoother. This back-and-forth scoring action helps to remove burrs and irregular parts, providing a better heating effect for the heating assembly 100. The flat and smooth opening surface is conducive to the adhesion of the heating assembly 100, thereby enhancing the bonding effect. Compared with direct bonding after the initial scoring, the cable opening that has been scored twice by the first thorn 420 can be more tightly bonded, improving the strength and durability of the repaired part. Multiple scoring also helps to remove impurities and contaminants at the opening, further improving the cleanliness and bonding quality of the bonding interface. The secondary scoring function of the first thorn 420 significantly improves the quality of cable repair. By optimizing the opening surface and enhancing the bonding effect, the service life of the repaired cable is extended. The first thorn 420 enables the extrusion assembly 400 to adapt to different types of cable damage. The cutting force and number of times can be adjusted according to actual needs to optimize the opening, thereby enhancing the adaptability and flexibility of the repair device. Example 3

[0016] In order to further improve the applicability and convenience of the use of the substation cable damage rapid repair device of the present application, the embodiment of the present application optimizes and improves the first thorn, specifically: like Figure 6-7 As shown, the extrusion assembly 400 further includes a second thorn; The first thorn 420 of the roller 410 away from the magnet 411 in the width direction is the second thorn 430; The second thorn 430 is a triangular shape; The number of the second thorns 430 is four.

[0017] After adjusting the angle, the first thorn 430 can effectively serve as a supporting structure, firmly supporting the cable sheath after being cut by the first thorn 420, and ensuring that the structural integrity of the cable is not destroyed during the repair process. The first thorn 430 is longer than the first thorn 420, and is tilted by adjusting the angle of the magnet 411 on the roller so as to be used in conjunction with the first thorn 420. This tilted design enables the first thorn 430 to further act on the cable sheath at a certain angle after the first thorn 420 completes the cutting, thereby generating additional support and cutting effects. After the first thorn 420 completes the cutting, the first thorn 430 can serve as a supporting point, and the cable sheath will shrink or deform due to internal tension or external factors. At this time, it can prevent the cable sheath from shrinking and maintain the flatness and stability of the bonding surface. The first thorn 430 can also enhance the cutting effect to a certain extent. It can further cut the cable sheath on the basis of the first thorn 420, making the bonding surface smoother, which is conducive to the bonding of the heating component. The coordinated use of the first thorn 420 and the first thorn 430 makes the cutting and supporting process of the cable sheath more efficient. They can quickly complete the stripping of the cable sheath and the preparation of the bonding surface, saving time for subsequent steps. The combination of multiple cuts and support is conducive to the adhesion of the heating component after heating and the recovery of cable performance, thereby ensuring the quality of the repair and improving the efficiency and effect of the repair work.
