However, this operation method is labor-intensive, time-consuming and labor-intensive. In addition, when removing foreign objects on higher lines, it is not conducive to using handheld tools such as insulating rods for cleaning.

[0037] First, the device needs to be installed on the cable 3. In the initial state of the device, the slot 2 14 on the gear ring 11 and the slot 1 13 on the fixed plate 9 are arranged horizontally in the same direction. Therefore, the cable 3 can be placed in the fixing mechanism 1 by passing through the slot 1 13 and the slot 2 14, and then the motor 1 6 is started to rotate the one-way threaded rod 5. The threaded sleeve 1 7 connected to the spiral transmission on the outer surface of the one-way threaded rod 5 will carry the rack 8 for displacement, and the rack 8 is engaged with the gear ring 11, so the gear ring 11 will rotate, so that the slot 1 13 and the slot 2 14 are offset, and the device can be preliminarily installed on the cable 3.

[0038] The second fixing mechanism includes a limiting groove 15 opened on the left end surface of the fixing plate 9, and a transmission groove 16 is opened on the left end surface of the gear ring 11.

The slide bar 18 is fixedly connected to the slider 17, and the outer surface of the slide bar 18 is rotatably connected to a roller 19. The limiting groove 15, the transmission groove 16, the slider 17, the slide bar 18 and the roller 19 are each correspondingly provided in three groups, and are dispersedly arranged in a ring shape, and the three groups of rollers 19 are all arranged close to the cable 3. The second fixing mechanism has two groups corresponding to the two groups of the first fixing mechanism.

[0039] Secondly, when the gear ring 11 rotates, the slide bar 18 inside the transmission groove 16 opened on the end face of the gear ring 11 will move along with the gear ring 11, and the slide bar 18 is fixedly connected to the slider 17 slidably connected in the limit groove 15.

[0040] This solution is achieved by setting up a fixing mechanism 1 and a fixing mechanism 2. The fixing mechanism 1 preliminarily fixes the device on the cable 3 and can perform fixed installation on cables 3 of different diameters. The fixing mechanism 2 performs secondary stabilization between the cable 3 and the device to avoid shaking during the operation of the device, which may affect the normal operation of the device.

[0041] The transmission mechanism includes a bidirectional threaded rod 21 rotatably connected to the lower side of the inner part of the support frame 4, a gear 20 is fixedly installed at the front end of the unidirectional threaded rod 5, a gear 22 is fixedly installed at the front end of the bidirectional threaded rod 21, the gear 20 is meshed with the gear 22, the rear side of the outer surface of the bidirectional threaded rod 21 is spirally connected with a threaded sleeve 23, both sides of the outer surface of the threaded sleeve 23 are rotatably connected with a connecting rod 1 24, the left and right ends of the support frame 4 are provided with a slide groove 27, the interior of the slide groove 27 is slidably connected with two groups of sliders 28, the two groups of sliders 28 are respectively fixedly connected with the corresponding threaded sleeve 23 and the threaded sleeve 3 25, the front side of the outer surface of the bidirectional threaded rod 21 is spirally connected with the threaded sleeve 3 25, the threaded sleeve 3 25 Both sides of the outer surface of the platform 1 are rotatably connected with connecting rods 26, the left and right sides of the bidirectional threaded rod 21 are provided with top blocks 29, the connecting rods 1 24 and 26 on the same side are rotatably connected to the corresponding top blocks 29, and the ends of the top blocks 29 are fixedly installed with connecting pieces 1 30, and notches 31 are provided at both ends of the platform 1, and the inside of the notches 31 is rotatably connected with a transmission rod 32, one end of the transmission rod 32 is fixedly installed with a connecting piece 2 33, the lower end of the connecting piece 2 33 is fixedly installed with a sliding column 35, the upper end of the connecting piece 1 30 is fixedly installed with a sliding sleeve 36, the sliding column 35 is slidably connected with the sliding sleeve 36, and a spring 34 is fixedly installed between the connecting piece 1 30 and the connecting piece 2 33, and the spring 34 is sleeved on the outer surfaces of the sliding sleeve 36 and the sliding column 35.

[0042] The rotation of the unidirectional threaded rod 5 will drive the gear 1 20 to rotate, and the gear 1 20 will mesh with the gear 2 22 on the bidirectional threaded rod 21, thereby driving the bidirectional threaded rod 21 to rotate, and the threaded sleeve 23 and the threaded sleeve 3 25 connected by the spiral transmission on the outer surface of the bidirectional threaded rod 21 will synchronously displace relative to each other, the threaded sleeve 23 carries the connecting rod 1 24 to displace, and the threaded sleeve 3 25 carries the connecting rod 26 to displace, and the connecting rod 1 24 and the connecting rod 26 on the same side are rotatably connected to the corresponding top block 29, thereby driving the two groups of top blocks 29 to expand to both sides, and the top block 29 is rotatably connected to the lower end of the transmission rod 32 through the connecting piece 1 30, the spring 34, the sliding sleeve 36, the sliding column 35, etc., thereby driving the transmission rod 32 to deflect counterclockwise, and the setting of the spring 34, the sliding sleeve 36, and the sliding column 35 can offset the displacement difference between the circular motion of the transmission rod 32 and the linear motion of the top block 29, and the other ends of the transmission rods 32 on both sides of the platform 1 will be displaced toward the cable 3.

[0043] In this solution, a transmission mechanism is set up, and the device and the cable 3 are fixed while driving the transmission mechanism. The transmission mechanism will place the cleaning mechanism and the cutting mechanism at both ends of the cable 3 respectively and close to the cable 3, so that the cleaning mechanism and the cutting mechanism can operate smoothly.

[0044] The cutting mechanism includes four slots 37 opened at the other end of the transmission rod 32, and one group of the slots 37 are internally rotatably connected with a driving wheel 38 and a cutting wheel 40, and the cutting wheel 40 is arranged on the right side of the driving wheel 38. A motor 2 39 is fixedly installed at the rear end of the transmission rod 32, and the end of the output shaft of the motor 2 39 is fixedly connected to the driving wheel 38. The driving wheel 38 is arranged close to the cable 3, and the cutting wheel 40 is arranged at a certain distance from the cable 3.

[0045] The driving wheel 38 on one set of transmission rods 32 with cutting mechanisms will be close to the cable 3, and the cutting wheel 40 will be two millimeters away from the cable 3. At this time, the motor 2 39 is started to rotate the driving wheel 38, so that the entire device can be displaced on the cable 3. When encountering plastic bags, ropes and other garbage wrapped around the cable 3, the foreign matter wrapped around the cable 3 will increase the outer contour size of the cable 3. Therefore, in the forward process of the present invention, the cutting wheel 40 will contact the foreign matter and cut it, and the garbage will automatically slide down under the influence of gravity after being cut.

[0046] In this solution, a cutting mechanism is provided, and the motor 2 39 drives the driving wheel 38 to rotate, so that the device moves on the cable 3. Foreign matter entangled on the cable 3 will increase the outer contour size of the cable 3. Therefore, during the forward movement of the present invention, the cutting wheel 40 will contact the foreign matter and cut it.

[0047] The cleaning mechanism includes a rotating shaft 41 rotating inside another group of slots four 37, a driven wheel 42 is fixedly installed on the outer surface of the rotating shaft 41, the driven wheel 42 is arranged close to the cable 3, both ends of the rotating shaft 41 extend to the outside of the slot four 37, and a worm 43 is fixedly installed at both ends of the rotating shaft 41, a worm wheel 46 is meshed on the upper side of the worm 43, a rotating rod 45 is fixedly installed on the right side of the worm 43, a cleaning brush 47 is fixedly installed on the outer surface of the rotating rod 45, the right end of the rotating rod 45 is rotatably connected to a support member 44, and the support member 44 is fixedly connected to the transmission rod 32.

[0048] The driven wheel 42 on the other set of transmission rods 32 will synchronously cling to the cable 3. As the equipment runs on the cable 3, the driven wheel 42 will rotate and carry the rotating shaft 41 to move. The rotating shaft 41 will drive the worm 43 to rotate. The worm wheel 46 on the rotating rod 45 is engaged with the worm 43, so the rotating rod 45 will rotate synchronously and drive the cleaning brush 47 to rotate, so as to clean the bird droppings and other debris on the cable 3. Secondly, the ultrasonic flaw detector 2 can perform flaw detection on the cable 3 and record the internally damaged cable 3, and then transmit it to the ground receiving end through the wireless transceiver.

[0049] In this solution, a cleaning mechanism is provided to synchronously follow the operation of the cutting mechanism. When the device moves on the cable 3, it drives the cleaning brush 47 in the cleaning mechanism to rotate at high speed, thereby cleaning the dust and bird droppings on the outer surface of the cable 3, thereby avoiding flashover, short circuit and other problems of the cable 3 caused by foreign objects such as birds.

[0050] Instructions for use: First, the device needs to be installed on the cable 3. In the initial state of the device, the slot 2 14 on the gear ring 11 and the slot 1 13 on the fixed plate 9 are arranged horizontally in the same direction. Therefore, the cable 3 can be placed in the fixing mechanism 1 by passing through the slot 1 13 and the slot 2 14. Then, the motor 1 6 is started to rotate the one-way threaded rod 5. The threaded sleeve 1 7 connected to the spiral transmission on the outer surface of the one-way threaded rod 5 will carry the rack 8 for displacement, and the rack 8 is engaged with the gear ring 11. Therefore, the gear ring 11 will rotate, so that the slot 1 13 and the slot 2 14 are offset. The device can be initially installed on the cable 3. Secondly, while the gear ring 11 rotates, the sliding rod 18 inside the transmission groove 16 opened on the end face of the gear ring 11 will follow the gear ring 11. The sliding rod 18 is fixedly connected to the sliding block 17 slidably connected in the limiting groove 15. Therefore, under the cooperation between the limiting groove 15 and the transmission groove 16, the sliding rod 18 will be driven to move toward the cable 3. The three groups of sliding rods 18 will synchronously drive the roller 19 to move toward the cable 3, and make the roller 19 close to the cable 3, so that the device and the cable 3 are reinforced for the second time. Secondly, the rotation of the one-way threaded rod 5 will drive the gear 1 20 to rotate, and the gear 1 20 will mesh with the gear 2 22 on the two-way threaded rod 21, so it will drive the two-way threaded rod 21 to rotate, and the threaded sleeve 23 and the threaded sleeve 3 25 connected by the spiral transmission on the outer surface of the two-way threaded rod 21 will be synchronously relatively displaced, and the threaded sleeve 23 will carry the connecting rod 1 24 to move, and the threaded sleeve 3 25 will carry the connecting rod 2 26 to move. The connecting rod 1 24 and the connecting rod 26 on the same side are rotatably connected with the corresponding top blocks 29, thereby driving the two groups of top blocks 29 to expand to both sides. The top blocks 29 are rotatably connected with the lower end of the transmission rod 32 through the connecting piece 1 30, the spring 34, the sliding sleeve 36, the sliding column 35, etc., thereby driving the transmission rod 32 to deflect counterclockwise, and the setting of the spring 34, the sliding sleeve 36, and the sliding column 35 can offset the displacement difference between the circular motion of the transmission rod 32 and the linear motion of the top block 29. The other ends of the transmission rods 32 on both sides of the platform 1 will move toward the cable 3, and the driving wheel 38 on one group of the transmission rods 32 with the cutting mechanism will be close to the cable 3, and the cutting wheel 40 will be two millimeters away from the cable 3. At this time, the motor 2 39 is started to rotate the driving wheel 38, and the entire device can be moved. The device is displaced on the cable 3. When encountering garbage such as plastic bags and ropes wrapped around the cable 3, the foreign matter wrapped around the cable 3 will increase the outer contour size of the cable 3. Therefore, during the forward movement of the present invention, the cutting wheel 40 will contact the foreign matter and cut it. The garbage will automatically slide down under the influence of gravity after being cut, and the driven wheel 42 on the other set of transmission rods 32 will synchronously stick to the cable 3. As the device runs on the cable 3, the driven wheel 42 will rotate and carry the rotating shaft 41 to move. The rotating shaft 41 will drive the worm 43 to rotate. The worm wheel 46 on the rotating rod 45 is engaged with the worm 43, so the rotating rod 45 will rotate synchronously and drive the cleaning brush 47 to rotate, so that the bird droppings and other debris on the cable 3 can be cleaned.Secondly, the ultrasonic flaw detector 2 can detect the cable 3 and record the internally damaged cable 3, and then transmit it to the ground receiving end through the wireless transceiver.

[0051] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
