Description

Technical Field

[0001] The invention relates to the technical field of cable maintenance, in particular to a power cable maintenance device. Background Art

[0002] The components of power cables mainly include conductors, insulation layers, fillers, inner sheaths and outer sheaths. The maintenance of power cables is an important task to ensure the safe and reliable operation of the cable system. The maintenance work mainly includes appearance inspection, insulation inspection, conductor connection inspection and grounding inspection. Among them, insulation damage of power cables is one of the common problems in power systems, which may cause cable failures, power outages and equipment damage.

[0003] After searching, the Chinese patent with patent number CN117996645B includes a mounting plate, a mounting frame, a movable frame and a visual sensor. The bottom of the mounting plate is connected to the mounting frame, and the movable frame is slidably connected to the mounting frame. The movable frame is connected to multiple visual sensors for detecting damage to the cable. It also includes a rotating frame, a visual sensor 2, a hot air gun, a moving mechanism, a pressing mechanism, a placing mechanism and a cutting mechanism.

[0004] In the above patent, the damage can be automatically detected and the damaged position can be automatically repaired through the cooperation of visual sensor 1, visual sensor 2 and insulating tape, which has higher work efficiency; at the same time, the movable end of the electric push rod is used to drive the cutter to move to the left, automatically cutting off the insulating tape, reducing manual operation to further improve the automation level of the device; on the other hand, in the process of the device moving along the cable, the bristles can brush off the stains on the cable, so that the device has a cleaning function while avoiding stains blocking the damaged position of the cable and affecting the detection effect of visual sensor 1 and visual sensor 2.

[0005] However, due to structural influences in the above-mentioned patent, the distance between the moving wheel and the clamping wheel cannot be changed, resulting in a fixed cable size applicable to the above-mentioned patent.

DETAILED DESCRIPTION

[0033] 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.

[0034] Embodiment 1:

[0035] See also Figures 1 to 9 The present invention provides a technical solution: a power cable maintenance device, comprising a repair component for repairing the appearance damage of the cable and a walking component for controlling the advancement of the device, characterized in that: the walking component is installed on the outer contour of the cable to be detected 1, and the repair component is connected to the inner contour of the cable to be detected 1 by limited sliding;

[0036] A fixed frame 11 is passed through the outer contour of the cable 1 to be detected and is connected with limited sliding. Two fixing frames 12 distributed up and down and front and back are fixedly connected to the inner contours of the two ends of the fixed frame 11. A guide wheel 13 is passed through and rotatably connected at one end of the two fixing frames 12 away from the fixed frame 11. The outer contours of the two guide wheels 13 are connected with the outer contour of the cable 1 to be detected in a limited rotational manner. A positioning ring 14 is fixedly connected to the inner contour of the middle section of the fixed frame 11. The positioning ring 14 is connected with a traveling component in a limited transmission manner. A counterweight 15 is fixedly connected to the inner wall of one end of the fixed frame 11. A detection component for detecting damage to the cable appearance is arranged near the traveling component inside the fixed frame 11.

[0037] In this device, the cable to be detected 1 is used as the power cable to be detected, and its size can be adjusted accordingly according to actual usage requirements. The fixed frame 11 limits the overall structure of the device to protect it from interference from the external environment with the maintenance work. The fixed frame 12 and the guide wheel 13 cooperate to guide and position the cable to be detected 1. The positioning ring 14 further utilizes the motion transmission of the walking component to realize the automatic advancement of the fixed frame 11. The counterweight block 15 offsets the center of gravity of the entire device so that the fixed frame 11 pulls the part of the cable to be detected 1 located in the fixed frame 11, thereby fully exposing the appearance damage on the upper surface of the cable to be detected 1 to improve the detection efficiency of subsequent detection components.

[0038] Embodiment 2:

[0039] See also Figures 4 to 5, this embodiment further explains Example 1, the walking assembly includes a transmission frame 2, the middle section of the transmission frame 2 is penetrated and limitedly slidably connected to the inner contour of the positioning ring 14, one end of the transmission frame 2 is provided with a ratchet portion 21, and the end of the transmission frame 2 close to the ratchet portion 21 is limitedly slidably connected to a deflection ring 22, a connecting rod 23 is fixedly connected to the outer contour of the deflection ring 22, and an adjusting ball 24 is fixedly connected to the end of the connecting rod 23 away from the deflection ring 22, and a positioning spring 25 sleeved on the outer contour of the connecting rod 23 is fixedly connected between the outer contour of the connecting rod 23 and the deflection ring 22, and the positioning spring 25 is located inside the ratchet portion 21, and a transmission ring 26 is fixedly connected to the axis of the deflection ring 22 away from the transmission frame 2, and a driving roller 27 is fixedly connected between the end of the deflection ring 22 close to the transmission frame 2 and the inner contour of the transmission frame 2.

[0040] Both ends of the driving roller 27 are provided with driving motors and are fixedly connected to the output shaft of the motor. The driving roller 27 is made of flexible material. The inner contour of the transmission ring 26 is provided with annular bristles. The positioning spring 25 is initially set to a stretched state. The upper half of the connecting rod 23 is intermittently clamped with the ratchet portion 21.

[0041] First, the operator installs the device on the outer surface of the cable to be detected 1. The fixed frame 11, the transmission frame 2 and the deflection ring 22 are all composed of two symmetrical semicircular structures, so that the fixed frame 11, the transmission frame 2 and the deflection ring 22 can be disassembled and installed by using the pin shaft. After the device is installed, the operator adjusts the adjustment ball 24 so that the drive roller 27 fits tightly on the outer contour of the cable to be detected 1. Then the drive motors at both ends of the drive roller 27 work and drive the drive roller 27 to rotate. Under the action of the friction force between the drive roller 27 and the cable to be detected 1, the drive roller 27 drives the transmission frame 2 to start spiral movement. The drive roller 27 further pushes the cable to be detected 1 through the positioning ring 14 and drives the entire device to start moving.

[0042] It should be noted that, when the operator adjusts the adjusting ball 24, the adjusting ball 24 is first pulled outward, at which time the stretching degree of the positioning spring 25 is further increased and the clamping relationship between the connecting rod 23 and the ratchet portion 21 is released, and then the operator rotates the adjusting ball 24 along the ratchet portion 21. Under the connection action of the connecting rod 23, the deflection ring 22 rotates synchronously with the adjusting ball 24, and the two ends of the driving roller 27 are fixedly connected to the transmission frame 2 and the deflection ring 22 respectively. At this time, the rotation of the deflection ring 22 with the adjusting ball 24 will cause the two ends of the driving roller 27 to be twisted. Rotation, because the driving roller 27 is made of flexible material, the torsion of the driving roller 27 at this time will cause the driving roller 27 to be in close contact with the cable to be detected 1 and the friction between the driving roller 27 and the cable to be detected 1 will increase synchronously, and then, the motors at both ends of the driving roller 27 drive the driving roller 27 to rotate, and under the action of the friction between the driving roller 27 and the cable to be detected 1, the rotation of the driving roller 27 will cause the driving roller 27 as a whole to move in an axial spiral along the cable to be detected 1, thereby causing the walking assembly to drive the device as a whole to start moving according to the above process description.

[0043] On the other hand, in the process of the transmission frame 2 and the deflection ring 22 spirally moving along the cable to be detected 1, the clamping relationship between the connecting rod 23 and the ratchet portion 21 can prevent the deflection ring 22 from sliding relative to each other to a limited extent, thereby reducing the friction between the driving roller 27 and the cable to be detected 1; at the same time, the annular bristles arranged inside the transmission ring 26 and the close contact between the driving roller 27 and the cable to be detected 1 can effectively clean the outer surface of the cable to be detected 1, further reducing the interference of stains attached to the outer surface of the cable to be detected 1 on the subsequent detection process.

[0044] Embodiment three:

[0045] See also Figure 6 to Figure 7 , this embodiment further explains Example 2, the detection component includes a fixing ring 3, three annularly symmetrically distributed cameras 31 are fixedly connected to the inner contour of the fixing ring 3, three annularly symmetrically distributed fixing blocks 32 are fixedly connected to the outer contour of the fixing ring 3, the end of the fixing block 32 away from the fixing ring 3 is fixedly connected to the inner contour of the fixing frame 11, a connecting plate 33 is fixedly connected to the outer contour of the top of the fixing ring 3, the bottom end of the connecting plate 33 is fixedly connected to a liquid storage tube 34, a reset spring 35 is fixedly connected to the inner contour of the top of the fixing ring 3, the bottom end of the reset spring 35 is fixedly connected to a piston 36, both sides of the piston 36 are penetrated and fixedly connected with a transmission rod 37, and the bottom end of the piston 36 is limitedly slidably connected to the inner contour of the liquid storage tube 34.

[0046] During the movement of the device, the detection component uses the camera 31 to capture images of the outer surface of the cable 1 to be detected. At this time, the counterweight 15 causes the center of gravity of the fixed frame 11 and the entire device to shift, so that the part of the cable 1 to be detected in the fixed frame 11 is deflected at a small angle, and the fixed frame 11 is further limited and guided by the cooperation of the fixed frame 12 and the guide wheel 13. Since the upper surface of the cable is usually more exposed to the external environment in the cable installed at high altitude, it is easy to be directly contacted or affected by various external factors, so that the appearance damage is usually more likely to appear on the upper surface of the cable. At this time, the deflected cable 1 to be detected is stretched so that the appearance damage on the upper surface of the cable 1 to be detected is fully exposed to improve the subsequent detection efficiency.

[0047] It should be noted that the fixing block 32 is used to fix the fixing ring 3 and the cable to be detected 1, so that the fixing ring 3 moves synchronously with the cable to be detected, and the illumination angle of the camera 31 to the outer surface of the cable to be detected 1 is fixed. The liquid storage tube 34 contains cable repair liquid, which is mainly composed of polymer resin and additives, and has good fluidity and thermosetting properties. The lifting and lowering movement of the piston 36 inside the liquid storage tube 34 can squeeze the repair liquid along the bottom end of the liquid storage tube 34 and drip it on the top of the outer surface of the cable to be detected 1. The connecting plate 33 fixes the liquid storage tube 34 and the fixing ring 3 to limit the height of the liquid storage tube 34 so that relative movement occurs between the piston 36 and the liquid storage tube 34. Along with the movement of the piston 36, the stretching degree of the reset spring 35 changes synchronously to reset the piston 36, and the transmission rod 37 transmits the movement of the subsequent repair component to the piston 36, so that the piston 36 starts to lift and lower.

[0048] Embodiment 4:

[0049] See also Figure 8This embodiment further explains the third embodiment, the repair component includes a fixed plate 4, the fixed plate 4 is penetrated and limitedly rotated by a transmission shaft 45 near the top, the transmission shaft 45 is fixedly connected to the outer contour of one end of the fixed plate 4, the transmission shaft 45 is fixedly connected to the outer contour of the drive gear 42, the fixed plate 2 41 is fixedly connected to the outer contour of the drive shaft 45 near the drive gear 42, the outer contour of the bottom end of the drive gear 42 is meshed and transmission-connected with a ring gear 43, the ring gear 43 is limitedly slidably connected to the opposite surfaces of the fixed plate 4 and the fixed plate 2 41, A threaded portion 48 is provided on the outer contour of the end of the transmission shaft 45 away from the fixed plate 14, the transmission shaft 45 passes through and is threadedly connected to the fixed ring 3 and the connecting plate 33, a heat sealing shovel 44 is fixedly connected to the inner contour of the ring gear 43, a connecting spring 46 is fixedly connected to the middle of the end of the fixed plate 2 41 away from the fixed plate 14, the end of the connecting spring 46 away from the fixed plate 2 41 is fixedly connected to the outer contour of the fixed ring 3, a transmission block 47 is fixedly connected to the bottom of the end of the fixed plate 2 41 away from the fixed plate 14, and the transmission block 47 is intermittently connected to the transmission rod 37.

[0050] The limited length of the threaded portion 48 accounts for one third of the total length of the transmission shaft 45. The heat sealing shovel 44 is provided with a uniformly surrounding resistance wire inside. The driving gear 42 is driven by an external motor and is fixedly connected to the output shaft of the motor.

[0051] When damage is detected on the surface of the cable 1 to be tested, the driving gear 42 starts to rotate and drives the transmission shaft 45 and the ring gear 43 to rotate synchronously. The rotation of the transmission shaft 45 drives the driving gear 42, the fixing plate 1 4, the fixing plate 2 41 and the ring gear 43 to move toward the fixing ring 3 due to the threaded connection between the threaded portion 48 and the fixing ring 3, that is, the repair component as a whole moves toward the detection component; at the same time, the rotation of the ring gear 43 synchronously drives the heat sealing shovel 44 to rotate, and the heat sealing shovel 44 rotates around on the outer surface of the cable 1 to be tested.

[0052] As the repair assembly moves forward, the connecting spring 46 is gradually compressed and the bottom end of the transmission block 47 contacts and squeezes the transmission rod 37. Under the squeezing action of the transmission block 47, the transmission rod 37 drives the piston 36 to start lifting and lowering movement. At this time, the repair liquid inside the liquid storage tube 34 is squeezed out and drips onto the damaged position on the upper surface of the cable 1 to be detected; as the repair assembly moves further, the heat sealing shovel 44 moves to the damaged position on the outer surface of the cable 1 to be detected. At this time, the rotation of the heat sealing shovel 44 can evenly smooth the repair liquid on the upper surface of the cable 1 to be detected, and the heating of the heat sealing shovel 44 causes the repair liquid to solidify at the damaged position on the outer surface of the cable 1 to be detected, thereby completing the repair operation of the appearance damage of the cable 1 to be detected.

[0053] It should be noted that during the movement of the repair component, since the limited length of the threaded portion 48 accounts for one third of the total length of the transmission shaft 45, when the repair component moves to the point where the threaded portion 48 is disengaged from the fixing ring 3, the repair component reaches the limit distance and the connecting spring 46 is used to fix the overall position of the repair component, thereby ensuring the work quality of the heat sealing shovel 44 in the thermal curing and leveling operation of the repair liquid.

[0054] Embodiment five:

[0055] See also Fig. 9 , this implementation further illustrates the third embodiment, the cable to be detected 1 is internally provided with a control module for adjusting the operating state of the device, and the control module includes a processor, a receiver and a signal device;

[0056] The processor is configured to receive image information from the camera 31 and perform binarization processing before sending it to the receiver;

[0057] The receiver is configured to receive information from the processor and send it to a corresponding signaler according to the type of information;

[0058] The signaler is configured to send the signal of the receiver to the corresponding motor and control the operation of the motor.

[0059] The signal device inside the cable to be detected 1 is electrically connected to the driving motor of the driving roller 27 , and the signal device inside the cable to be detected 1 is electrically connected to the motor of the driving gear 42 .

[0060] First, as the device moves forward, the camera 31 captures images of the outer surface of the cable 1 to be detected and uses the processor to binarize the captured images. When an abnormal edge area appears in the image information after the binarization process, it indicates that the outer surface of the cable 1 to be detected has been detected to have appearance damage. At this time, the signal device controls the drive motors at both ends of the drive roller 27 to stop rotating, and the device stops moving; further, the signal device controls the drive gear 42 to start rotating and the heat sealing shovel 44 to start heating. The rotation of the drive gear 42 causes the repair component to approach the detection component and squeeze the repair liquid out of the liquid storage tube 34. The heat sealing shovel 44 further smoothes the repair liquid and, as the heat sealing shovel 44 is heated, the repair liquid solidifies at the appearance damage on the outer surface of the cable 1 to be detected to complete the repair operation of the cable 1 to be detected.

[0061] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
