Therefore, in order to extend the service life of the cable, it is necessary to repair the damaged area on the cable.

[0003] The patent with the application number CN202410097611.6 discloses a cable fault detection device for overhead lines, including a support bottom frame. The upper end of the support bottom frame is fixedly provided with a hexagonal outer frame, and an overhead cable is arranged inside the hexagonal outer frame. Rotating monitoring parts and driving parts are respectively sleeved on the front and rear outer surfaces of the overhead cable. A solar photovoltaic panel is installed on the outer surface of the hexagonal outer frame. Compared with the prior art, the above solution detects the cable during the movement on the cable. The detection contents mainly include damage, corrosion, and aging on the outer surface of the cable, and can mark the cable bad points for convenient subsequent repair, replacing the traditional manual detection, without human risk, greatly improving the detection efficiency, and effectively reducing the power failure caused by cable problems. However, it does not effectively repair the damaged area on the cable, and still requires manual winding and judgment of the cable.

[0004] Moreover, when repairing the cable, due to the long length of the cable and its swing in the natural environment, it greatly affects the repair rate during the cable repair process and there is a situation of repair failure.

[0005] Therefore, in order to solve the above technical problems, the present invention proposes a potential insulation cable repair device. Summary of the Invention

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] like Figure 1 - Figure 8 As shown, a potential insulated cable repair device includes a connecting component 1 used to carry the entire device, and the connecting component 1 is respectively connected to a carrying component 2 at both ends along the thickness direction. The two carrying components 2 are rotatably provided with a movable rod 5 at one end away from the connecting component 1, and the movable rod 5 is rotatably provided with a clamping component 3 at one end away from the carrying component 2. The two ends of the movable rod 5 are respectively hinged to the carrying component 2 and the clamping component 3, that is, the two carrying components 2 and the component structures connected to the carrying component 2 are the same, and when in use, the connecting component 1, the carrying component 2 and the clamping component 3 are put on the cable to facilitate the repair of the cable.

[0032] The connecting component 1 includes a limiting shell 101, and the supporting component 2 is connected to the limiting shell 101. A constraint hole 103 for the cable to pass through is opened in the middle area of the limiting shell 101, and two mounting blocks 6 for fixing the required clips for maintenance are connected in the constraint hole 103. When in use, the constraint hole 103 is opened so that the cable to be repaired is located in the constraint hole 103, and the cable is located between the two mounting blocks 6, waiting to be repaired, and the two ends of the limiting shell 101 along the width direction are respectively connected with the interference component 4, wherein the interference component 4 is made of insulating material in the present invention, and when the maintenance and fixing device is used, when multiple groups of cables at the same position need to be fixed and repaired, the two adjacent maintenance and fixing devices can be clamped with each other to improve its stability during use, and when a single cable is repaired and fixed, the edge cable is interfered with by the interference component 4, thereby expanding the operating range during the maintenance process, reducing the situation of accidental contact with the gas cable, and improving operational safety.

[0033] A repair sleeve 7 for cable repair is snap-fitted on the mounting block 6. Threaded grooves are provided at both ends of the repair sleeve 7 distributed along the length direction, which is convenient for users to use tape or other flexible parts to wind and fix the repair sleeve 7 and the cable, so as to improve the stability after fixation and avoid position deviation on the repair sleeve 7. When only the surface of the cable is damaged, resulting in problems with its use safety, the damaged part is covered by the repair sleeve 7, and the position of the repair sleeve 7 is fixed by the staff using waterproof tape. When the cable is broken, first, the cable break is fastened by the clamping component 3 and made to approach each other, then the cable is connected to the repair sleeve 7 to complete the fixation and covering protection of the cable. In order to facilitate the use of the repair sleeve 7 on the cable, in this invention, the repair sleeve 7 is preferably divided into two parts and connected to the two mounting blocks 6 respectively.

[0034] It should be noted that in this invention, the repair sleeve 7 can be a housing for covering and protecting, or a two-way connecting cylinder with a connecting end, or other components convenient for cable repair.

[0035] Furthermore, in order to fix the position of the connecting component 1 and assist in improving the stability of the connecting component 1 during use, the clamping component 3 includes a clamping sleeve 301. A notch is provided on the clamping sleeve 301, which is convenient for the clamping sleeve 301 to be sleeved on the cable in the middle of the cable. One end of the clamping sleeve 301 close to the limiting shell 101 is hinged to the movable rod 5. A plurality of elastic rods 303 are connected to the inner ring of the clamping sleeve 301. During use, the user can compress the elastic rods 303 and maintain the compressed length unchanged. The ends of the elastic rods 303 far from the clamping sleeve 301 are all connected with movable plates 302. The movable plates 302 are distributed in an arc array in the clamping sleeve 301. When the device is in use, first, the movable plates 302 are pressed to make the elastic rods 303 contract and maintain the compressed length of the elastic rods 303 unchanged, that is, at this time, the position of the movable plates 302 is close to the inner ring of the clamping sleeve 301. Then, through the notch on the clamping sleeve 301, the cable is moved into the inside of the clamping sleeve 301, and then the length of the elastic rods 303 is restored, and the movable plates 302 are driven to contact the surface of the cable, realizing the fixation of the position of the clamping component 3.

[0036] At the same time, in order to facilitate the identification of the damaged position on the cable, a current sensing coil and a screen for displaying the detection result of the current sensing coil are provided on the movable plate 302. When the current sensing coil identifies an area with current, its reading can be displayed on the screen, which is convenient for users not to miss any repair.

[0037] When dealing with various different faults on the cable line, it is necessary to adjust the fixing state and fixing method of the maintenance fixing device in real time to improve the maintenance speed of the cable line during the maintenance process. Further, both of the two bearing components 2 include connecting rings 202, and gaps for the cable line to enter are also provided on the connecting rings 202. A plurality of buffer rods 203 are connected to the outer periphery of the connecting ring 202. One end of the buffer rod 203 far from the connecting ring 202 is connected with a movable block 201. One end of the movable block 201 close to the clamping component 3 is hinged with a movable rod 5. During the use of the maintenance fixing device, after the cable line is constrained by the clamping sleeve 301 and the connecting ring 202, the tension of the cable line in the maintenance area is adjusted by adjusting the distance between the clamping sleeve 301 and the connecting ring 202. When the clamping sleeve 301 and the connecting ring 202 are at a normal distance, the movable block 201 is close to the connecting ring 202, and the buffer rod 203 is in a shortened state. When the clamping sleeve 301 moves towards the end close to the connecting ring 202, it drives the movable rod 5 to rotate, so that the included angle between the movable rod 5 between the clamping sleeve 301 and the movable block 201 changes. And when the movable rod 5 moves, it drives the movable block 201 to move, and the buffer rod 203 extends, so as to adapt to the cable line maintenance in different environments.

[0038] It should be noted that the buffer rod 203 is movably connected to the connecting ring 202. At the same time, a return spring is connected to the buffer rod 203. When the movable block 201 and the connecting ring 202 are in contact with each other, the return spring is at its normal length. When the movable block 201 and the connecting ring 202 move away from each other, the return spring is in an extended state.

[0039] Further, in order to facilitate passing the cable line through the limiting shell 101 and ensure that the maintenance fixing device can effectively maintain the cable line, the limiting shell 101 includes a fixing part 1011 and a hinged part 1012. The fixing part 1011 and the hinged part 1012 are unilaterally hinged through a hinge. That is, during use, in the area where the hinged part 1012 is connected to the fixing part 1011, one side can be separated from each other, and the other side is in a hinged state. Among them, two carrying blocks 6 are respectively located on the fixing part 1011 and the hinged part 1012. The connecting ring 202 is connected to the fixing part 1011. During use, unlock the connection between the hinged part 1012 and the fixing part 1011, and then control the hinged part 1012 to rotate around the position hinged to the fixing part 1011, so that the constraint hole 103 is opened. After placing the cable on the constraint hole 103, then close the constraint hole 103 by rotating the hinged part 1012, so that the cable line is located in the constraint hole 103.

[0040] Furthermore, during use, in order to ensure that the repair sleeve 7 contacts the cable body under the action of the carrying block 6 and realizes the repair of the cable, the connecting component 1 also includes a control nut 102, the extended end of the control nut 102 passes through the fixing part 1011 and is connected to the carrying block 6, and the control nut 102 can rotate on the surface of the carrying block 6, and the control nut 102 is threadedly connected to the fixing part 1011. When the cable is just in the constraint hole 103, the position of the carrying block 6 is not regulated by the control nut 102. After the damaged position of the cable is determined, the carrying block 6 is driven to move toward one end close to each other by rotating the control nut 102, and finally the position of the cable is fixed. At the same time, in order to ensure that the control nut 102 will not loosen due to the vibration of the cable when restricting the carrying block 6, a tightening spring is provided between the control nut 102 and the fixing part 1011 to ensure the stability of the control nut 102 when it is stationary.

[0041] When repairing the cables, the distance between the two adjacent cables is relatively close, which affects the user's operating space during repair. Furthermore, the resistance component 4 includes a resistance plate 401, wherein the resistance plate 401 is made of insulating material. When it interferes with the adjacent cables, no conductivity will occur, and the structures of the resistance plates 401 on both sides of the limiting shell 101 are different, but they are nested in each other. A telescopic rod 402 is connected to one end of the resistance plate 401 close to the connecting component 1. The telescopic rod 402 is connected to the connecting component 1, and the movement of the resistance plate 401 is controlled by the telescopic rod 402, so that the resistance plate 401 does not interfere with the outside without maintenance. If multiple groups of cables in the same area need to be repaired and fixed, the two adjacent resistance plates 401 are clamped together to connect them into an integral structure, thereby improving stability during use.

[0042] It should be noted that the inner diameter of the connecting ring 202 in the bearing component 2 is larger than the inner diameter of the snap sleeve 301 in the snap assembly 3, ensuring that the bearing component 2 will not interfere with the use of the snap assembly 3 during use, ensuring the stability of the cable during maintenance, and improving maintenance efficiency.

[0043] When the cable needs to be repaired, first move the connecting component 1 under the cable that needs to be repaired, then open the hinge part 1012, and connect the cable to the bearing component 2 and the clamping component 3 through the gap in turn, and then pass through the constraint hole 103 to connect with the connecting component 1, so as to ensure that the maintenance fixture constrains the cable.

[0044] When the cable is only severely damaged on the surface and the position is determined, and its normal use is affected, the repair sleeve 7 is connected to the carrier block 6 at this time. The length of the elastic rod 303 is controlled to extend, driving the movable plate 302 to contact the surface of the cable, and the position of the limiting shell 101 is fixed by using the frictional force. At this time, by rotating the control nut 102, the carrier block 6 is driven to move, so that the carrier block 6 compresses the position of the cable, and the repair sleeve 7 is prompted to limit the cable. Finally, it is ensured that the repair sleeve 7 is closely attached to the surface of the cable and the damaged position is covered. Then, the staff fixes the position of the repair sleeve 7 to complete the repair of the cable.

[0045] However, when repairing the cable, the cable may sag or shake due to external natural factors, which affects the limiting efficiency and accuracy of the carrier block 6 on it. At this time, the clamping sleeve 301 is prompted to move towards the end close to the bearing component 2, thereby driving the movable rod 5 to rotate, shortening the distance between the clamping component 3 and the bearing component 2. Furthermore, the movable plate 302 is driven to move through the elastic rod 303, so that the clamping sleeve 301 is fixed to the cable. When the cable is in a relaxed state, at this time, the buffer rod 203 drives the clamping sleeve 301 to move, and the cable in the target area is tightened, reducing the shaking of the cable in the area to be repaired, improving the limiting efficiency of the carrier block 6 on the cable, and improving the repair rate of the cable.

[0046] At the same time, when repairing a single cable, since the distance between two adjacent cables is small, which affects the fixing operation of the user during the repair process, at this time, the length of the contact plate 401 is extended by the telescopic rod 402, prompting the contact plate 401 to contact the cable at the edge and driving it to move, improving the operating space of the cable to be repaired. And when multiple groups of cables at the same position need to be repaired and fixed, the adjacent two contact plates 401 can be mutually clamped to connect them into a whole, improving its stability during the fixing process.

[0047] After repairing the target position, the restriction of the movable plate 302 on the cable can be released, and at the same time, the two carrying blocks 6 are controlled to separate, so that the repair fixing device can move on the cable and approach the next area waiting for repair. During the movement of the connecting component 1 and the clamping component 3, the surface of the cable is identified by the electric sensing coil on the movable plate 302 to avoid the situation that the damaged area is too small to be detected. That is, when there is a breakage on the cable, the electric sensing coil will be charged and displayed on the clamping sleeve 301 at this time, prompting the staff that there is a damaged position in this area and prompting them to repair it. When the movable plate 302 abuts against the cable, the electric sensing coil can identify the current flow situation on the cable to ensure that there is no open circuit when the cable is repaired. That is, when the cable is still in a conductive state after repair, the electric sensing coil can detect that there is current passing through at this time. When the cable is in an open circuit state after repair, there is no current display on the electric sensing coil at this time.

[0048] When necessary, but the cable use environment is harsh and there is still a leakage phenomenon after multiple repairs, the repair fixing device can be used to fix the target cable position at this time, and the connecting component 1 and the clamping component 3 are used to maintain the target cable. That is, during use, the limiting shell 101 is moved to the middle area of the target cable, and the movable plate 302 is used to fix the cable, so that the limiting shell 101 will not move relatively with the cable, and it is ensured that the cable between the two clamping sleeves 301 will not move excessively and collide, so as to reduce the probability of cable damage and improve the service life of the cable.

[0049] It should be noted that in this article, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
