[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0021] like Figure 1 - Figure 8 As shown, a novel ground potential insulated cable repair device includes a connecting component 1 used to carry the device as a whole, and the connecting component 1 is respectively connected to a carrying component 2 at both ends along the thickness direction, and 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, and 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 components 2 are the same, and when in use, the connecting component 1, the carrying component 2 and the clamping component 3 are sleeved on the cable line to facilitate the repair of the cable line.

[0022] The connecting component 1 includes a limiting shell 101, and the bearing 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. Two mounting blocks 6 for fixing the required fixing parts for maintenance are connected in the constraint hole 103. When in use, the cable to be repaired is located in the constraint hole 103 by opening the constraint hole 103, and the cable is located between the two mounting blocks 6, waiting for maintenance. The limiting shell 101 is connected to the two ends along the width direction with the interference components 4 respectively, wherein the interference components 4 are made of insulating material in the present invention, and during the use of the maintenance and fixing device, when multiple groups of cables at the same position need to be fixed and repaired, two adjacent maintenance and fixing devices can be connected to each other to improve their stability during use, and when a single cable is repaired and fixed, the edge cable is interfered 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.

[0023] A maintenance sleeve 7 for repairing the cable is clamped on the carrying block 6, wherein both ends of the maintenance sleeve 7 along the length direction are provided with threaded grooves, so that when the user uses tape or other flexible parts to wrap and fix the maintenance sleeve 7 and the cable, the stability after fixation is improved and the position displacement on the maintenance sleeve 7 is avoided. When the cable is only damaged on the surface, which causes problems with its safety in use, the damaged part is covered by the maintenance sleeve 7, and the position of the maintenance sleeve 7 is fixed by the staff using waterproof tape. When the cable is broken, the broken part of the cable is first tightened and brought close to each other by the clamping component 3, the cable is connected to the maintenance sleeve 7, and the fixing and covering protection of the cable are completed. In order to facilitate the use of the maintenance sleeve 7 on the cable, in the present invention, the maintenance sleeve 7 is preferably divided into two parts, and they are respectively connected to the two carrying blocks 6.

[0024] It should be noted that, in the present invention, the repair sleeve 7 can be a protective shell, or a two-way connecting tube with a connecting end, or other components that are convenient for repairing the cable.

[0025] Furthermore, in order to fix the position of the connecting component 1 and to help improve the stability of the connecting component 1 when in use, the clamping component 3 includes a clamping sleeve 301, wherein the clamping sleeve 301 is provided with a notch to facilitate the clamping sleeve 301 to be sleeved on the cable in the middle of the cable, and the end of the clamping sleeve 301 close to the limiting shell 101 is hinged to the movable rod 5, and a plurality of elastic rods 303 are connected to the inner ring of the clamping sleeve 301. When in use, the user can compress the elastic rod 303 and maintain the compressed length unchanged, and the end of the elastic rod 303 away from the clamping sleeve 301 The connections are all connected with movable plates 302, and the movable plates 302 are distributed in an arc-shaped array in the clamping sleeve 301. When the device is used, the elastic rod 303 is first contracted by pressing the movable plate 302, and the compressed length of the elastic rod 303 is maintained unchanged, that is, the position of the movable plate 302 is close to the inner ring of the clamping sleeve 301. At this time, the cable is moved to the inside of the clamping sleeve 301 through the notch on the clamping sleeve 301, and then the length of the elastic rod 303 is controlled to rebound, and the movable plate 302 is driven to contact the surface of the cable, so as to fix the position of the clamping component 3.

[0026] At the same time, in order to facilitate the identification of the damaged location on the cable, an inductive coil and a screen for displaying the detection results of the inductive coil are set on the movable plate 302, and when the inductive coil identifies an area where current exists, its indication can be displayed on the screen, so that the user will not miss any repairs during use.

[0027] In order to deal with various 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 rate of the cable line during the maintenance process. Furthermore, the two bearing components 2 both include a connecting ring 202, and the connecting ring 202 is also provided with a notch for the cable line to enter. The outer periphery of the connecting ring 202 is connected with a plurality of buffer rods 203, and the end of the buffer rod 203 away from the connecting ring 202 is connected with a movable block 201, and the end of the movable block 201 close to the clamping component 3 is hinged to the movable rod 5. In the process of using the maintenance fixing device, the clamping sleeve 301 and the connecting ring 202 are used to complete After constraining the cable, the tension of the cable in the maintenance area is regulated 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 tightly attached to the connecting ring 202, and the buffer rod 203 is in a shortened state. When the clamping sleeve 301 moves toward one end close to the connecting ring 202, the movable rod 5 is driven to rotate, so that the angle between the movable rod 5 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 to extend, so as to adapt to cable maintenance in different environments.

[0028] It should be noted that the buffer rod 203 and the connecting ring 202 are movably connected, and a return spring is connected to the buffer rod 203. When the movable block 201 and the connecting ring 202 are in conflict with each other, the return spring is at a normal length. When the movable block 201 and the connecting ring 202 are away from each other, the return spring is in an extended state.

[0029] Furthermore, in order to facilitate the passage of the cable through the limiting shell 101 and ensure that the maintenance and fixing device can effectively repair the cable, the limiting shell 101 includes a fixing portion 1011 and a hinged portion 1012, and the fixing portion 1011 and the hinged portion 1012 are unilaterally hinged by a hinge, that is, when in use, the area where the hinged portion 1012 is connected to the fixing portion 1011 can be separated from each other on one side, and the other side is in a hinged state, wherein the two carrying blocks 6 are respectively located on the fixing portion 1011 and the hinged portion 1012, and the connecting ring 202 is connected to the fixing portion 1011. When in use, the connection between the hinged portion 1012 and the fixing portion 1011 is unlocked, and then the hinged portion 1012 is controlled to rotate around the position hinged with the fixing portion 1011, so that the constraint hole 103 is opened, and after the cable is placed on the constraint hole 103, the constraint hole 103 is closed by rotating the hinged portion 1012, so that the cable is located in the constraint hole 103.

[0030] 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 portion 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 portion 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 set between the control nut 102 and the fixing portion 1011 to ensure the stability of the control nut 102 when it is stationary.

[0031] 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, and no conduction occurs when it collides with the adjacent cables. The structures of the resistance plates 401 on both sides of the limiting shell 101 are different, but they are nested in each other's shape. A telescopic rod 402 is connected to one end of the resistance plate 401 close to the connecting component 1, and the telescopic rod 402 is connected to the connecting component 1. The movement of the resistance plate 401 is controlled by the telescopic rod 402, so that the resistance plate 401 does not conflict 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.

[0032] 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-in sleeve 301 in the snap-in component 3, ensuring that the bearing component 2 will not interfere with the use of the snap-in component 3 during use, ensuring the stability of the cable during maintenance, and improving maintenance efficiency.

[0033] When the cable needs to be repaired, first move the connecting component 1 under the cable that needs to be repaired, then open the hinged part 1012, and connect the cable to the bearing component 2 and the clamping component 3 through the notch in turn, and then pass through the restraining hole 103 to connect with the connecting component 1, so as to ensure that the maintenance fixing device restrains the cable.

[0034] When the cable is only seriously damaged on the surface and the position is determined, affecting its normal use, the repair sleeve 7 is connected to the carrying block 6, the length of the elastic rod 303 is controlled to extend, the movable plate 302 is driven to contact the surface of the cable, and the friction force is used to fix the position of the limiting shell 101. At this time, the control nut 102 is rotated to drive the carrying block 6 to move, so that the carrying block 6 compresses the position of the cable and prompts the repair sleeve 7 to restrict the cable. Finally, it is ensured that the repair sleeve 7 is in close contact with the surface of the cable and the damaged position is covered. The position of the repair sleeve 7 is fixed by the staff to achieve the maintenance of the cable.

[0035] However, when repairing the cable, the cable may sag or shake due to external natural factors, which will affect the limiting efficiency and positioning accuracy of the carrying block 6. At this time, the clamping sleeve 301 is prompted to move toward 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, and then driving the movable plate 302 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, the buffer rod 203 drives the clamping sleeve 301 to move, and the cable in the target area is tightened, thereby reducing the shaking of the cable in the area that needs to be repaired, improving the limiting efficiency of the carrying block 6 on the cable, and improving the repair rate of the cable.

[0036] At the same time, when repairing a single cable, the distance between two adjacent cables is small, which affects the user's fixing action during the repair process. At this time, the telescopic rod 402 drives the length of the contact plate 401 to extend, so that the contact plate 401 contacts the cable at the edge and drives it to move, thereby increasing the operating space for the cable that needs to be repaired. When multiple groups of cables need to be repaired and fixed at the same position, the two adjacent contact plates 401 can be connected to each other to form a whole, thereby improving their stability during the fixing process.

[0037] After the target position is repaired, the restriction of the movable plate 302 on the cable can be released, and the two carrying blocks 6 can be controlled to separate, so that the maintenance fixture can move on the cable line and approach the next area waiting for maintenance. During the movement of the connecting component 1 and the clamping component 3, the surface of the cable line is identified by the inductive coil on the movable plate 302 to avoid the damage being undetected due to being too small. That is, when there is damage on the cable, the inductive coil will be energized and displayed on the clamping sleeve 301, prompting the staff that there is a damaged position in this area and prompting them to perform repairs. When the movable plate 302 conflicts with the cable, the current flow on the cable can be identified by the inductive coil to ensure that the cable will not be broken during maintenance. That is, when the cable is still in passage after maintenance, the inductive coil can identify that there is current passing through. When the cable is broken after maintenance, no current is displayed on the inductive coil.

[0038] When necessary, but the cable is used in a harsh environment and leakage still exists after multiple repairs, the target cable position can be fixed by using a maintenance fixing device, and the target cable can be maintained by using the connecting component 1 and the clamping component 3. That is, when in use, the limiting shell 101 is moved to the middle area of ​​the target cable, and the movable plate 302 is used to fix it to the cable, so that the limiting shell 101 will not move relative to the cable, and ensure 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 increase the service life of the cable.
