Description

Technical Field

[0001] This application relates to the technical field of power maintenance and protection, and in particular to a de-icing device for power cables. Background Technology

[0002] Power line icing has always been one of the most serious disasters in power systems both at home and abroad. In order to avoid serious power supply accidents caused by cable icing, it is necessary to carry out de-icing operations on the cables in a timely manner.

[0003] The existing de-icing device for power cables is installed on the cable by manually climbing a tower. Then, a motor drives rollers that come into contact with the cable to move the de-icing device along the cable. The de-icing device removes the ice layer on the cable by means of knocking, cutting, heat melting and vibration to complete the de-icing operation.

[0004] Although the aforementioned de-icing device removes the ice layer from the cables, it requires manual climbing of the tower to install on the cables, increasing the difficulty and time of installation and resulting in low installation efficiency. Summary of the Invention

[0005] In order to facilitate the installation of de-icing devices on cables and improve the installation efficiency of de-icing devices, this application provides a de-icing device for power cables.

[0006] This application provides a de-icing device for power cables, which adopts the following technical solution:

[0007] A de-icing device for power cables includes a connecting plate, a drone assembly, and a de-icing assembly. The drone assembly and the de-icing assembly are respectively connected to both sides of the connecting plate. The drone assembly is used to drive the de-icing assembly to approach the icy cable. The de-icing assembly includes a clamping part and a de-icing part. The clamping part is connected to the connecting plate and is used to clamp onto the icy cable. The de-icing part is disposed on the clamping part and is used to remove the ice layer on the cable.

[0008] By adopting the above technical solution, the drone component can carry the de-icing component to fly high and get close to the icy cable. After the de-icing component gets close to the icy cable, it is clamped onto the icy cable by the clamping part, so that the de-icing part can be quickly installed on the icy cable. This allows the de-icing part to easily start removing the ice layer from the cable. As a result, the installation of the de-icing device does not require manual climbing of the tower, which reduces the difficulty of installing the de-icing device on the icy cable and reduces the installation time of the de-icing device. This makes it easy to install the de-icing device on the cable and improves the installation efficiency of the de-icing device.

[0009] Optionally, the clamping part includes a clamping shaft, a clamping plate, and an electric telescopic component. Two clamping shafts, clamping plates, and electric telescopic components are symmetrically arranged. The clamping shaft is rotatably connected to the connecting plate, and the clamping plates correspond one-to-one with the clamping shafts. One side of the clamping plate is fixed to the clamping shaft. The two electric telescopic components are located on the opposite sides of the two clamping plates. The electric telescopic components are hinged between the connecting plate and the clamping plates. The electric telescopic components are used to drive the two clamping plates to clamp onto the icing cable.

[0010] By adopting the above technical solution, the electric telescopic component can drive the clamping plate to rotate around the rotation axis of the clamping shaft. Under the flight action of the drone component, the icing cable can easily be positioned between the two clamping plates. By driving the clamping plate with the electric telescopic component, the two clamping plates can clamp onto the icing cable, thereby making it easy for the de-icing part to be quickly installed on the icing cable through the clamping action of the clamping plates.

[0011] Optionally, the de-icing unit includes ice-breaking hammers and ice-breaking rods. There are two sets of ice-breaking hammers, which are respectively set on one side of two clamping plates that are close to each other. Each set contains multiple ice-breaking hammers, which are symmetrically arranged. The hammer rods of the ice-breaking hammers are hinged to the clamping plates. There are multiple ice-breaking rods, which are respectively set between two symmetrical ice-breaking hammers. The two ends of the ice-breaking rods are slidably connected to the hammer rods of the two ice-breaking hammers.

[0012] By adopting the above technical solution, when the clamping plate is clamped on the ice-covered cable, the sliding ice-breaking rod approaches the ice-covered cable, and the two ends of the ice-breaking rod slide along the hammer shaft of the ice-breaking hammer, so that the two symmetrical ice-breaking hammers swing in a direction that approaches each other, so that the hammer head of the ice-breaking hammer can strike the ice-covered cable, thereby causing the ice layer on the cable to fall off under the striking action.

[0013] Optionally, each set of icebreakers is connected to an icebreaking drive unit, which includes an icebreaking telescopic rod. The icebreaking telescopic rod is fixed on the side of the clamping plate away from the other clamping plate. The movable end of the icebreaking telescopic rod slides through the clamping plate. The movable end of the icebreaking telescopic rod is fixedly connected to an icebreaking connecting rod. The icebreaking connecting rod is fixedly connected to the icebreaking rods connected to all the icebreakers in the corresponding set.

[0014] An electromagnet and a magnetic block are installed inside the rodless cavity of the ice-breaking telescopic rod. The electromagnet and the magnetic block are positioned opposite each other. The electromagnet is fixed to the ice-breaking telescopic rod, and the magnetic block is fixed to the movable end of the ice-breaking telescopic rod. An elastic rope is fixed between the electromagnet and the magnetic block. The elastic rope is used to drive the magnetic block closer to the electromagnet. The electromagnet is electrically connected to an intermittent power supply controller. The intermittent power supply controller is used to control the electromagnet to be intermittently energized. When the electromagnet and the magnetic block are energized, the polarities on the sides that are close to each other are the same.

[0015] By adopting the above technical solution, the intermittent power supply controller can control the electromagnet to be intermittently energized, so that the magnetic thrust between the electromagnet and the magnetic block exists intermittently. When the electromagnet is energized, the magnetic thrust between the electromagnet and the magnetic block can drive the ice-breaking telescopic rod to extend and cause the elastic rope to accumulate elasticity. The ice-breaking telescopic rod drives the ice-breaking rod to slide through the ice-breaking connecting rod, so that the ice-breaking hammer can strike the ice-covered cable. When the electromagnet is de-energized, the elastic rope between the electromagnet and the magnetic block can drive the ice-breaking telescopic rod to retract through elasticity, so that the ice-breaking hammer moves away from the ice-covered cable. Thus, during the intermittent energization of the electromagnet, the ice-breaking hammer can strike the ice-covered cable cyclically.

[0016] Optionally, each end of the clamp plate is provided with a support portion, which includes a support rod, a support plate, and a support spring. There are two or more support rods, support plates, and support springs, and they correspond one-to-one. The support rod slides through the clamp plate, the support plate is fixed at the end of the support rod away from the other clamp plate, and the support spring is fixed between the support plate and the clamp plate. The support spring is used to drive the end of the support rod away from the support plate to support the icing cable.

[0017] By adopting the above technical solution, the support rods on the two clamping plates can abut against the icy cable when the clamping plates clamp the icy cable. Under the elastic force of the support spring, the support rods provide support to the clamping plates with the icy cable as the support point. With the cooperation of all the support rods at both ends of the two clamping plates, the clamping plates can be in an elastic support state relative to the icy cable. On the one hand, the support spring can buffer the vibration transmitted from the icy cable to the clamping plate. On the other hand, with the cooperation of the support rods and the support spring, the two ends of the clamping plates can be stably supported on the icy cable and the cable without ice layer respectively, so that the position of the cable relative to the clamping plate can always be in a stable state.

[0018] Optionally, the drone component includes a drone body, a connecting rod fixedly connected to the drone body, a rotating shaft fixedly connected to the connecting rod, the rotating shaft rotatably connected to a connecting plate, and the axis of rotation is perpendicular to the axis of rotation of the clamp rotating shaft. A transmission component is connected between the rotating shaft and the clamp rotating shaft, and the transmission component includes a push rod, a bidirectional telescopic rod, a rack and pinion, and a gear.

[0019] There are two push rods symmetrically arranged, each corresponding to a clamping shaft. One end of each push rod is fixed to the clamping shaft. The bidirectional telescopic rod is located between the two push rods, and the two movable ends of the bidirectional telescopic rod are respectively hinged to the ends of the two push rods away from the clamping shaft. The rack is fixed to the bidirectional telescopic rod and slides through the connecting plate. The rack meshes with the gear, and the gear is coaxially fixed to the rotating shaft. When the two clamping plates abut, the connecting rod is parallel to the connecting plate.

[0020] By adopting the above technical solution, when the electric telescopic component drives the clamping plate to swing, the clamping plate drives the clamping shaft to rotate, the clamping shaft drives the push rod to rotate, the push rod drives the bidirectional telescopic rod to move, the bidirectional telescopic rod drives the rack to slide, the rack drives the gear to rotate, and the gear drives the connecting rod and the drone body to swing through the rotating shaft, so that the connecting rod is parallel to the connecting plate, so that the drone body can change from a vertical setting to a horizontal setting. The horizontally set drone body can pull the connecting plate and the clamping plate to move along the cable, so that the drone body can not only carry the de-icing component close to the iced cable, but also pull the de-icing component to move along the cable.

[0021] Optionally, a cable groove is provided on the steering side of the drone body. When the connecting rod is parallel to the connecting plate, the cable is inserted into the cable groove. A heat fusion assembly is provided on the drone body. The heat fusion assembly includes two heating wires, which are symmetrically arranged on both sides of the cable groove and connected to the drone body.

[0022] By adopting the above technical solution, after the main body of the drone swings, the cable can be inserted into the cable groove. The two heating wires on both sides of the cable groove can heat and melt the ice layer on the cable, reducing the difficulty of the ice hammer in removing the ice layer from the cable.

[0023] Optionally, both ends of each heating wire are slidably disposed in a groove opened on the main body of the UAV. The sliding direction of the two heating wires is either towards each other or away from each other. A variable resistance slider is embedded in the bottom of the groove. The end of the heating wire abuts against the variable resistance slider and is electrically connected. When the heating wire is located at the end of the groove away from the cable groove, the heating wire and the variable resistance slider are in an open circuit state. When the heating wire is located at the end of the groove close to the cable groove, the heating wire and the variable resistance slider are in a short circuit state.

[0024] A swing rod is hinged to one end of the heating wire near the bottom of the cable groove. An adjustment rod is hinged to the ends of the two swing rods away from the heating wire. The adjustment rod is slidably connected to the main body of the drone along the opening direction of the cable groove. The end of the adjustment rod away from the swing rod extends into the cable groove from the bottom of the cable groove.

[0025] A thermoplastic spring is fixed between the two swing rods. The thermoplastic spring is used to drive the two swing rods to swing in a direction away from each other. When the cable is inserted into the cable groove in a state without ice layer, the end of the adjusting rod abuts against the cable, and the heating wire is located at the end of the slide groove away from the cable groove.

[0026] By adopting the above technical solution, the thickness of the ice layer on the cable determines the displacement of the adjusting rod after the cable is inserted into the cable groove. The greater the thickness of the ice layer, the greater the displacement of the adjusting rod. At the same time, the amplitude of the swing of the two swing rods driven by the adjusting rod is also greater, so that the heating wire is closer to the cable groove. The current is supplied to the heating wire through the variable resistance slider. Under the conductivity of the variable resistance slider, the closer the heating wire is to the cable groove, the greater the current flowing through the heating wire. Therefore, when the thickness of the ice layer is greater, the heating effect of the heating wire on the ice layer is more obvious, so that the heating of the ice layer by the heating wire can be automatically adjusted according to the thickness of the ice layer.

[0027] Optionally, a solar battery is fixedly mounted on the main body of the drone, and the solar battery is electrically connected to the main body of the drone, the electric telescopic component, the intermittent power supply controller, and the variable resistance slider.

[0028] By adopting the above technical solution and using solar batteries for power, the service life of the drone body, electric telescopic parts, electromagnets, and heating wires is extended, and the flight time of the de-icing device is increased.

[0029] Optionally, the ice-breaking hammer has multiple ice-breaking spikes fixedly attached to its hammerhead.

[0030] By adopting the above technical solution, the icebreaker breaks ice through ice-breaking spikes, thus improving the ice-breaking effect of the icebreaker.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] 1. By setting up the drone body, clamping plate and electric telescopic component, the de-icing device can be easily installed on the cable, improving the installation efficiency of the de-icing device;

[0033] 2. By setting up an ice-breaking hammer, ice-breaking rod, ice-breaking telescopic rod, electromagnet, magnetic block, elastic rope, and intermittent power supply controller, the ice layer on the cable can be easily knocked away;

[0034] 3. By setting push rods, bidirectional telescopic rods, racks and pinions, the main body of the UAV can pull the clamping plate along the cable when the clamping plate is holding the cable;

[0035] 4. By setting up heating wire, variable resistance slider, swing rod, adjustment rod and heat melting spring, the difficulty of removing ice layer on the cable is reduced, and the heating of the ice layer by the heating wire can be adjusted according to the thickness of the ice layer.

[0045] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0046] This application discloses a de-icing device for power cables. (Refer to...) Figure 1 A de-icing device for power cables includes a connecting plate 1, a drone component 2, and a de-icing component 3. The drone component 2 and the de-icing component 3 are respectively connected to both sides of the connecting plate 1. The drone component 2 is used to drive the de-icing component 3 close to the icy cable. The de-icing component 3 is used to clamp onto the icy cable and remove the ice layer on the cable.

[0047] In use, the drone component 2 carries the de-icing component 3 to the icy cable. The de-icing component 3 clamps onto the icy cable and removes the ice layer on the cable, thus eliminating the need for manual installation of the de-icing device onto the icy cable. This allows the de-icing device to be easily installed on the cable, improving the installation efficiency of the de-icing device.

[0048] Reference Figure 1 The connecting plate 1 is rectangular and horizontally positioned. The drone component 2 is connected to the top surface of the connecting plate 1, and the de-icing component 3 is connected to the bottom surface of the connecting plate 1.

[0049] Reference Figure 2 The de-icing assembly 3 includes a clamping part 31, a de-icing part 32, an ice-breaking drive part 33, and a support part 34. The clamping part 31 includes a clamping shaft 311, a clamping plate 312, and an electric telescopic component 313. Two clamping shafts 311, clamping plates 312, and electric telescopic components 313 are symmetrically arranged along the length direction of the connecting plate 1. The axis of the clamping shaft 311 is parallel to the length direction of the connecting plate 1. Both ends of the clamping shaft 311 are rotatably connected to clamping connecting rods 3111. The clamping connecting rods 3111 are vertically arranged and their top ends are fixed to the bottom surface of the connecting plate 1. The clamping shaft 311 is rotatably connected to the connecting plate 1 through the clamping connecting rods 3111.

[0050] The clamping plates 312 correspond one-to-one with the clamping shafts 311. The clamping plates 312 are rectangular plates curved into an arc shape. The axis of the clamping plates 312 is parallel to the axis of the clamping shafts 311. One side of the clamping plate 312 along its length is fixed to the clamping shafts 311. The axes of the two clamping plates 312 are located on opposite sides. The electric telescopic components 313 are electric push rods. Two electric telescopic components 313 are located on opposite sides of the two clamping plates 312. The electric telescopic components 313 are hinged to the connecting plate 1. The movable end of the electric telescopic component 313 is hinged to the clamping plate 312 closest to it. The electric telescopic components 313 are used to drive the two clamping plates 312 to clamp onto the icing cable. When the opposite sides of the two clamping plates 312, away from the clamping shafts 311, abut against each other, the axes of the two clamping plates 312 coincide.

[0051] Reference Figure 2 , Figure 3 and Figure 4The de-icing unit 32 includes ice-breaking hammers 321 and ice-breaking rods 322. Two sets of ice-breaking hammers 321 are provided, each set positioned on one side of two clamping plates 312 close to each other. Each set contains multiple ice-breaking hammers 321, symmetrically arranged about the axis of the clamping plate 312. The hammer rods of the ice-breaking hammers 321 are hinged to the clamping plate 312, and are perpendicular to the axis of the clamping plate 312. A [missing information - likely a design element] is fixed to the head of the ice-breaking hammer 321. Multiple needle-shaped ice-breaking spikes 3211 are provided to facilitate the ice-breaking hammer 321 in breaking the ice layer on the cable; multiple ice-breaking rods 322 are rectangular rods and are provided. The multiple ice-breaking rods 322 are respectively provided between two symmetrical ice-breaking hammers 321. The two ends of the ice-breaking rods 322 are slidably connected to the hammer rods of the two ice-breaking hammers 321. The ice-breaking rods 322 are vertically arranged, and the sliding direction of the ice-breaking rods 322 and the hammer rods of the ice-breaking hammers 321 is the extension direction of the hammer rods of the ice-breaking hammers 321.

[0052] Reference Figure 3 There are two ice-breaking drive units 33, which correspond one-to-one with two sets of ice-breaking hammers 321. The ice-breaking drive unit 33 includes an ice-breaking telescopic rod 331, which is fixed on the side of the clamping plate 312 away from the other clamping plate 312. The movable end of the ice-breaking telescopic rod 331 slides through the clamping plate 312. The ice-breaking telescopic rod 331 is located in the middle of the clamping plate 312, and the telescopic direction is consistent with the diameter direction of the clamping plate 312.

[0053] The movable end of the ice-breaking telescopic rod 331 is fixedly connected to the ice-breaking connecting rod 332. The ice-breaking connecting rod 332 is rectangular in shape. The ice-breaking connecting rod 332 is fixedly connected to the ice-breaking rod 322 connected to all the ice-breaking hammers 321 in the corresponding group. The ice-breaking connecting rod 332 is parallel to the axis of the clamping plate 312.

[0054] An electromagnet 333 and a magnetic block 334 are installed inside the rodless cavity of the ice-breaking telescopic rod 331. Both the electromagnet 333 and the magnetic block 334 are circular blocks and are positioned opposite each other. The electromagnet 333 is fixed to the ice-breaking telescopic rod 331, and the magnetic block 334 is fixed to the movable end of the ice-breaking telescopic rod 331. An elastic rope 335 is fixed between the electromagnet 333 and the magnetic block 334. The elastic rope 335 is used to drive the magnetic block 334 closer to the electromagnet 333.

[0055] Reference Figure 2 and Figure 3 The electromagnet 333 is electrically connected to an intermittent power supply controller 336, which is used to control the electromagnet 333 to be intermittently energized. When the electromagnet 333 and the magnetic block 334 are energized, the polarities of the two sides that are close to each other are the same.

[0056] Reference Figure 2Four support parts 34 are provided, respectively located at the four ends of the two clamping plates 312. Each support part 34 includes a support rod 341, a support plate 342, and a support spring 343. There are two support rods 341, two support plates 342, and two support springs 343, which correspond to each other in pairs. The support rod 341 is rectangular and slides through the clamping plate 312. The sliding direction of the support rod 341 is consistent with the diameter direction of the clamping plate 312. The two support rods 341 are symmetrically arranged about the axis of the clamping plate 312. A roller 3411 is rotatably connected to the end of the support rod 341 near the other clamping plate 312. The rotation axis of the roller 3411 is perpendicular to the axis of the clamping plate 312.

[0057] The support plate 342 is circular and fixed to the end of the support rod 341 away from the roller 3411. The support spring 343 is sleeved on the support rod 341 and fixed between the support plate 342 and the clamping plate 312. The support spring 343 is used to drive the end of the support rod 341 away from the support plate 342 to support the icing cable.

[0058] In use, when the drone component 2 flies to the position of the icing cable, the two clamping plates 312 are clamped on both sides of the icing cable. The electric telescopic component 313 is activated, which drives the clamping plates 312 to clamp onto the icing cable. The support rod 341 is supported on the icing cable by the roller 3411 under the elastic force of the support spring 343. The intermittent power supply controller 336 controls the electromagnet 333 to be intermittently energized. The energized electromagnet 333 drives the magnetic block 334 to slide away from itself with magnetic thrust, so that the ice-breaking telescopic rod 331 is ejected and extended. The ice-breaking telescopic rod 331 drives the ice-breaking rod 322 to slide through the ice-breaking connecting rod 332. The ice-breaking rod 322 drives the two symmetrical ice-breaking hammers 321 to swing in a direction that moves closer to each other, so that the ice-breaking hammers 321 strike the icing cable. This makes it easy to quickly install the de-icing component 3 on the icing cable and to remove the ice layer from the cable.

[0059] Reference Figure 2 The drone component 2 includes a drone body 21, to which a connecting rod 22 is fixedly connected. The connecting rod 22 is rectangular and is positioned perpendicular to the drone body 21. A rotating shaft 23 is fixedly connected to one end of the connecting rod 22 away from the drone body 21. The rotating shaft 23 is rotatably connected to the top surface of the connecting plate 1, and the axis of rotation of the rotating shaft 23 is perpendicular to the axis of rotation of the clamping rotating shaft 311.

[0060] Reference Figure 2 and Figure 5A transmission assembly 4 connects the rotating shaft 23 and the clamping rotating shaft 311. The transmission assembly 4 includes push rods 41, bidirectional telescopic rods 42, racks 43, and gears 44. Two push rods 41 are symmetrically arranged and correspond one-to-one with the clamping rotating shaft 311. The push rods 41 are circular rods, and one end of the push rod 41 is fixed to the clamping rotating shaft 311 along its axial direction. The bidirectional telescopic rod 42 is horizontally arranged and located between the two push rods 41. The two movable ends of the bidirectional telescopic rod 42 are respectively hinged to the ends of the two push rods 41 that are away from the clamping rotating shaft 311.

[0061] The rack 43 is vertically arranged and its bottom end is fixed to the top of the bidirectional telescopic rod 42. The rack 43 slides vertically through the connecting plate 1. The gear 44 meshes with the rack 43 and is coaxially fixed to the rotating shaft 23. When the two clamping plates 312 abut, the connecting rod 22 is parallel to the surface of the connecting plate 1.

[0062] Reference Figure 1 A solar battery 24 is fixed on the side of the drone body 21 away from the connecting plate 1. The solar battery 24 is electrically connected to the drone body 21, the electric telescopic component 313 and the intermittent power supply controller 336 respectively.

[0063] In use, the solar battery 24 supplies power to the drone body 21, the electric telescopic component 313, and the intermittent power supply controller 336, extending the flight time of the drone body 21. When the clamping plate 312 clamps the icing cable, the clamping shaft 311 drives the bidirectional telescopic rod 42 to move through the push rod 41. The bidirectional telescopic rod 42 drives the rack 43 to slide, and the rack 43 drives the gear 44 to rotate. The gear 44 drives the connecting rod 22 to rotate through the rotating shaft 23, so that the connecting rod 22 is parallel to the surface of the connecting plate 1. This allows the drone body 21 to pull the de-icing component 3 along the cable after flying to the icing cable.

[0064] Reference Figure 6 and Figure 7 The main body 21 of the drone has a cable groove 211 on its turning side. The cable groove 211 is rectangular. When the clamping plate 312 clamps the ice-covered cable, the cable is inserted into the cable groove 211. The main body 21 of the drone is provided with a heat-melting component 5. The heat-melting component 5 includes two heating wires 51, which are symmetrically arranged on both sides of the cable groove 211. The heating wires 51 are serpentine and curved into an arc shape. Both ends of each heating wire 51 are slidably arranged in a sliding groove 212 opened on the main body 21 of the drone. The sliding groove 212 is rectangular. The sliding direction of the two heating wires 51 is either towards each other or away from each other.

[0065] Reference Figure 7The bottom of the groove 212 is fitted with a variable resistance slider 52, which is rectangular. The end of the heating wire 51 abuts against the variable resistance slider 52 and is electrically connected. The end of the variable resistance slider 52 near the cable groove 211 is electrically connected to the solar battery 24. When the heating wire 51 is located at the end of the groove 212 away from the cable groove 211, the heating wire 51 and the variable resistance slider 52 are in an open circuit state. When the heating wire 51 is located at the end of the groove 212 near the cable groove 211, the heating wire 51 and the variable resistance slider 52 are in a short circuit state.

[0066] A swing rod 53 is hinged to one end of the heating wire 51 near the bottom of the cable groove 211. The swing rod 53 is rectangular. An adjusting rod 54, also rectangular, is hinged to the ends of the two swing rods 53 away from the heating wire 51. The two swing rods 53 are symmetrically arranged on both sides of the adjusting rod 54. The adjusting rod 54 is slidably connected to the UAV body 21 along the opening direction of the cable groove 211. The end of the adjusting rod 54 away from the swing rod 53 extends into the cable groove 211 from the bottom. A thermoplastic spring 55 is fixed between the middle of the two swing rods 53, and the thermoplastic spring 55 is used to drive the two swing rods 53 to swing in opposite directions.

[0067] When the cable is inserted into the cable groove 211 without ice, the end of the adjusting rod 54 abuts against the cable, and the heating wire 51 is located at the end of the slide groove 212 away from the cable groove 211.

[0068] In use, when the clamping plate 312 clamps the ice-covered cable, the ice-covered cable is inserted into the cable groove 211. The ice-covered cable pushes the adjusting rod 54 to slide, and the adjusting rod 54 drives the swing rod 53 to swing, so that the heating wire 51 slides close to the ice-covered cable along the variable resistance slider 52. The solar battery 24 supplies power to the heating wire 51 through the variable resistance slider 52. Under the conductive effect of the variable resistance slider 52, the heating wire 51 is energized and heats the ice layer of the cable to melt the ice layer of the cable.

[0069] The implementation principle of the de-icing device for power cables in this application embodiment is as follows: When in use, the main body 21 of the drone is controlled to fly to the iced cable. The electric telescopic component 313 drives the clamping plate 312 to clamp onto the iced cable. The support rod 341 supports the clamping plate 312 on the iced cable. The intermittent power supply controller 336 controls the electromagnet 333 to be intermittently energized. The energized electromagnet 333 drives the ice-breaking telescopic rod 331 to extend. The ice-breaking telescopic rod 331 drives the ice-breaking hammer 321 to strike the iced cable through the ice-breaking connecting rod 332 and the ice-breaking rod 322 to remove the ice layer on the cable.

[0070] The clamping shaft 311 drives the rack 43 to slide via the push rod 41 and the bidirectional telescopic rod 42. The rack 43 drives the gear 44 to rotate, and the gear 44 drives the connecting rod 22 to rotate, so that the icing cable is inserted into the cable groove 211. The UAV body 21 drives the clamping plate 312 to move along the icing cable. The icing cable pushes the adjusting rod 54 to slide. The adjusting rod 54 drives the heating wire 51 to slide towards the icing cable via the swing rod 53. The heating wire 51 heats and melts the icing cable, so that the ice layer on the cable can be easily removed. This makes it easy to install the de-icing device on the cable and improves the installation efficiency of the de-icing device.

[0071] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
