Description

Technical Field

[0001] The present invention relates to the technical field of cable repair, and in particular to a power grid cable fault repair device. Background Art

[0002] By regularly inspecting, testing and maintaining cables, potential cable problems can be discovered in a timely manner, including whether there are foreign objects on the cables, whether the cable insulation layer is broken, etc. Therefore, the inspection and maintenance of high-voltage cables is an important measure to ensure the safe and stable operation of the cables.

[0003] The patent with publication number CN111740357B discloses an efficient cable maintenance device and maintenance method thereof, which includes a terminal device, support rods respectively connected to two adjacent poles, two groups of steel ropes connected between the two groups of support rods, and moving blocks movably installed on the two groups of steel ropes. The terminal device is installed on the moving block, and the moving block is also provided with a camera. Through the guiding effect of the steel rope, the moving block is moved along the steel rope to achieve accurate shooting of the cable by the camera. The image data captured by the camera is transmitted to the ground receiving end through the terminal device, so that the ground staff can patrol the cable and improve the staff's maintenance efficiency of the cable.

[0004] In the above scheme, before the camera inspects and shoots the cable, it is necessary to fix the two sets of support poles on the two sets of poles respectively, so that the two sets of steel ropes are pulled apart between the two sets of poles; firstly, due to the high height of the poles, the support poles are long, which is not conducive to the staff's transportation and installation of the support poles. Secondly, the terrain of the pole installation area is complex, which makes it very difficult for the staff to install the support poles, thus affecting the installation efficiency of the support poles, so that the above scheme has low efficiency in cable inspection; In response to the above problems, a Chinese invention patent with publication number CN118100019B discloses a cable maintenance machine, which uses a drone to enable the entire device to fly very flexibly to the cable to be repaired, eliminating the need for staff to manually place the device on the cable, thereby improving the cable inspection efficiency; although the cable maintenance machine has improved the cable inspection efficiency to a certain extent, it is limited by its own structure, has poor applicability, requires two cables to achieve its own positioning, has a small monitoring range, uses a single monitoring and inspection method (the only information that can be obtained is visual information), cannot conduct focused inspections, and is greatly affected by dirt on the cables, resulting in the information finally obtained being of little reference value.

[0005] Therefore, there is a need for a power grid cable fault inspection and repair equipment that has strong applicability, can achieve self-positioning with only one cable (cable), has a wide monitoring range, can obtain cable damage information through multiple channels, and can automatically clean the cable surface.

[0028] As Figure 6 shown, an extrusion positioning wheel assembly is provided on each of the top C-shaped plate 110 and the bottom C-shaped plate 120 of the third tube body 103. The extrusion positioning wheel assembly is positioned at the bottom of the top C-shaped plate 110 and the top of the bottom C-shaped plate 120 of the third tube body 103; the two extrusion positioning wheel assemblies are symmetric to each other and both abut against the side wall of the cable; the extrusion positioning wheel assembly includes a cylindrical wheel 161 and a floating frame 162; the cylindrical wheel 161 is a horizontally arranged funnel-shaped wheel body, with both ends positioned on the floating frame 162 and rotating around its own axis; the axial direction of the cylindrical wheel 161 is perpendicular to the length direction of the cable; the floating frame 162 includes a C-shaped frame body and a floating rod; the C-shaped frame body is a horizontally arranged C-shaped rigid frame body, which plays a role in carrying and positioning the cylindrical wheel 161, and the opening faces the cylindrical wheel 161 positioned thereon; the floating rod is a telescopic rod with an internal compression spring and always has a tendency to extend due to the presence of the internal compression spring; one end of the floating rod is fixed on the top C-shaped plate 110 or the bottom C-shaped plate 120, and the other end is fixed on the C-shaped frame body; during use, the two extrusion positioning wheel assemblies clamp the cable between them under the elastic force of the compression spring.

[0040] The power assembly is used to provide power for the operation of various components of the power grid cable fault repair equipment of this application, and the control unit plays a role in controlling the coordinated operation of various components of the power grid cable fault repair equipment. Both are prior arts and will not be described in detail here.

[0041] Preferably, the control unit is a combination of a terminal device, a programmable logic controller, a display and a remote control device.

[0042] When the power grid cable fault repair device of the embodiment of the present application is used: The maintenance personnel first install and fix the device of the present application on the bottom of the drone, and remotely control the drone to carry the device of the present application to the vicinity of the cable to be repaired; control the connecting rod body 130 to extend so that the top C-shaped plate 110 is separated from the bottom C-shaped plate 120; control the movement of the drone so that the three sleeve positioning tubes are sleeved on the cable to be repaired; control the connecting rod body 130 to contract so that the top C-shaped plate 110 and the bottom C-shaped plate 120 are spliced ​​and combined together, and the extrusion positioning wheel assembly clamps the cable; control the coated plate-like capsule 150 to expand and gradually cover the cable, and during the expansion process, all the exhaust holes 151 are gradually closed due to the resistance to the cable; control the top connector to extend so that the top camera assembly 410 is raised; control the camera assembly to start recording; control the coated plate-like capsule 150 on the first tube body 101 and the second tube body 102 to expand and contract alternately, and control the connecting telescopic rod 200 to expand and contract so that the entire device creeps on the cable (specifically: first control the second tube body 102 The coated plate-shaped sac 150 on the first tube body 101 contracts and controls the coated plate-shaped sac 150 on the first tube body 101 to expand, and then controls the connecting telescopic rod 200 to contract so that the second tube body 102 is close to the first tube body 101; then controls the coated plate-shaped sac 150 on the first tube body 101 to contract and controls the coated plate-shaped sac 150 on the second tube body 102 to expand, and then controls the connecting telescopic rod 200 to extend so that the second tube body 102 is away from the first tube body 101); during the movement of the device of the present application, the camera component continues to shoot, and the maintenance personnel observe the cables through the display to inspect the cables; when the device of the present application moves, it also plays a role in scrubbing the cables to prevent debris from affecting the inspection judgment; during the movement of the device of the present application, if the cable is severely damaged (larger protrusions or depressions), the exhaust hole 151 leaks and then causes the air pressure in the coated plate-shaped sac 150 to change, providing a reference and basis for the maintenance personnel.

[0043] Furthermore, during the movement, when the covering plate-shaped bag 150 contracts, the pressure on the cable will be reduced, and it will not completely leave the cable. When contracted, all the exhaust holes 151 are also closed against the cable.

[0044] The control unit records the change in air pressure in the coated plate-like bag 150 and the change in length of the connecting telescopic rod 200 in real time and generates graphs (line graphs and other graphs); the generated graphs can reflect to a certain extent whether the cable passed by the device of the present application is flat (if it is not flat, the exhaust hole 151 will discharge a certain amount of gas conductor after the coated plate-like bag 150 is deformed, and the air pressure in the coated plate-like bag 150 fluctuates) and whether the device of the present application moves smoothly (whether the change in length of the connecting telescopic rod 200 is continuous and smooth can reflect whether the cable surface is smooth and whether there are defects such as protrusions, cracks and pits that affect the elongation of the connecting telescopic rod 200); the control unit can mark these cable areas where problems may occur, and hand them over to manual review or alert maintenance personnel to focus on them.

[0045] Furthermore, when the gas pressure in the coated plate-shaped bag 150 decreases, the energy pump gas assembly 190 replenishes it in time under the control of the control unit.

[0046] Preferably, in order to avoid leaving scrubbing residue on the cable and affecting the observation effect, the width of the covering plate-like bag 150 fixed on the top C-shaped plate 110 is different from the width of the covering plate-like bag 150 fixed on the bottom C-shaped plate 120 (the direction of the covering plate-like bag 150 that is the same as the axial direction of the first tube body 101 is its length direction); the covering plate-like bag 150 on the bottom C-shaped plate 120 on the first tube body 101 is wider; the covering plate-like bag 150 on the top C-shaped plate 110 on the second tube body 102 is wider.

[0047] Preferably, the covering plate-shaped capsule 150 is formed by splicing and assembling a plurality of strip-shaped capsule bodies, and the length direction of the strip-shaped capsule body is the same as the axial direction of the sleeve positioning tube; each strip-shaped capsule body is provided with a built-in sensor 152 .

[0048] Preferably, Figure 7As shown, in order to more conveniently observe the air pressure changes in the coated plate-like bladder 150 and to amplify the amount of gas discharged by the coated plate-like bladder 150 when encountering a protrusion or depression on the cable, the coated plate-like bladder 150 is composed of a front bladder body 153 and a rear bladder body 154; the front bladder body 153 and the rear bladder body 154 are both plate-shaped rubber bladders, both are connected to the energy pump air component 190, and both expand and contract under the control of the control unit; the front bladder body 153 is mainly used for scrubbing, and the rear bladder body 154 is mainly used to reflect the cable status through the internal gas pressure change value; the front bladder body 153 is in front, and the rear sac 154 is in the rear; the exhaust hole 151 is only arranged on the rear sac 154; a plastic soft board 155 is fixed on the surface of the rear sac 154 away from the inner wall of the sleeve positioning tube; a plurality of rows of air holes are arranged on the fitting soft board 155, and these air holes correspond to the exhaust holes 151 one by one; when the fitting soft board 155 moves to the damaged area of ​​the cable (i.e., the convex, concave and cracked area), the amount of gas discharged is greater than that of the coated plate-shaped sac 150 without the fitting soft board 155 when encountering the same damaged area, and thus it is easier to be observed.
