Description

Technical Field

[0001] The present application relates to the field of cable deicing, and in particular to a deicing device and a deicing method for a power transmission line. Background Art

[0002] With the popularization of power facilities, some cables are arranged in an environment with low temperature all year round. Therefore, when the temperature drops below 0℃, the surface of the cable will gradually be covered with ice. The ice on the cable will greatly increase the weight of the cable, which may exceed the designed load-bearing capacity of the cable. This will bring huge pressure to the supporting structures of the cable, such as poles, towers, and bridges, and easily cause the supporting structures to deform, tilt, or even collapse. Ice coating may damage the insulation layer of the cable. When the ice layer melts, water may penetrate into the insulation layer, causing the insulation resistance to decrease and the leakage current to increase, thereby causing partial discharge or even short circuit failure.

[0003] Therefore, it is often necessary to remove ice from cables to ensure the normal operation of power facilities. The existing deicing methods usually use high-pressure water guns and other equipment to clean the lines, remove snow and ice through manual deicing, or spray deicing agents such as sodium chloride and calcium chloride on the surface of the cables to reduce the melting point of ice and melt the ice. This method is simple to operate, but the deicing agent may corrode the metal part of the cable and cause certain pollution to the environment.

[0004] In recent years, with the development of robot technology, robots specifically used for cable deicing have emerged. These robots can walk on cables and remove ice in various ways, such as using a powerful power device to push the deicing surface along the extension direction of the cable, or using high-pressure jets, etc. This type of robot deicing has the advantages of high efficiency and good safety, but because it requires a large power device or equipment such as gas tanks, it is expensive and heavy, which can easily put pressure on the cable. Low-cost and light-weight deicing robots have low deicing efficiency and are prone to residual ice on them. Summary of the invention

[0005] In order to overcome the shortcomings of the prior art of high deicing cost and heavy weight, the present application provides a power transmission line deicing device, which can achieve light weight, low deicing cost and high deicing efficiency.

[0006] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme: a power transmission line deicing device, comprising a mounting frame, a roller, a first ice-breaking wheel group and a second ice-breaking wheel group, the mounting frame is horizontally slidably provided with a first support and a second support, the roller is rotatably provided at the upper part of the mounting frame and is located on the side of the first support away from the second support, and the mounting frame is provided with a first linear drive component for driving the first support and the second support to move closer to or away from each other; The first ice-breaking wheel assembly includes two first ice-breaking wheels that move up and down on a first support, and a second linear drive assembly that drives the two first ice-breaking wheels to move toward or away from each other; The second ice-breaking wheel assembly includes two second ice-breaking wheels that move up and down on the second support, a third linear drive assembly that drives the two second ice-breaking wheels to move toward or away from each other, and a rotation drive assembly that drives at least one second ice-breaking wheel to rotate.

[0007] After adopting the above technical scheme, the working process of the de-icing device is as follows: first, the second linear drive component controls the two first ice-breaking wheels to move away from each other, and the third linear drive component controls the two second ice-breaking wheels to move away from each other, and the two cables that need to be de-iced are placed in the clamping space between the corresponding first ice-breaking wheel group and the second ice-breaking wheel group. Then, the second linear drive component and the third linear drive component control the corresponding wheel groups to move closer to each other, and generate positive pressure on the ice on the clamped cables until the ice layer breaks, so that the two ice-breaking wheels are close together. Subsequently, the first linear drive component controls the first ice-breaking wheel group and the second ice-breaking wheel group to move closer to each other, and the ice between the two groups of wheel groups is moved closer. The de-icing operation is then carried out by the first linear drive assembly to control the first ice-breaking wheel group and the second ice-breaking wheel group to move away from each other to the initial position, and then the second linear drive assembly controls the first ice-breaking wheel group to move away from each other, so that the rollers are directly against the cable or the ice. Finally, the rotation drive assembly controls the two second ice-breaking wheels to roll along the extension direction of the cable. During the rolling process, the two second ice-breaking wheels can crush the ice layer that has not been completely broken again to achieve more thorough de-icing. After the de-icing device moves to the next cable part that needs to be de-iced, the next de-icing operation is carried out.

[0008] The present application has the following advantages: the de-icing device first applies positive pressure to the ice on the cable to break it through the synergistic effect of the first ice-breaking wheel group and the second ice-breaking wheel group, then performs a breaking operation, and finally rolls and crushes the ice by rotating the second ice-breaking wheel, which can effectively remove the ice layer on the cable, achieve more thorough de-icing, and improve de-icing efficiency. Compared with traditional de-icing robots, the present device only uses a small number of ice-breaking wheels and motors, as well as some moving components, while ensuring the de-icing effect, thereby reducing the overall cost. Compared with using a high-powered power device to push and remove the ice, the present device uses positive pressure on the ice, and only a small force is needed to crush the ice surface. While the present device is low in cost, it avoids excessive pressure on the cable through a reasonable structural design, thereby improving the practicability and economy of the device.

[0009] Furthermore, when the two first ice-breaking wheels clamp the cable, the height of the roller is higher than the height of the first ice-breaking wheel located above.

[0010] With the above technical solution, this height setting makes the operation sequence of the device more reasonable. In the early stage of deicing, the ice-breaking wheel group can focus on squeezing and breaking the ice without being disturbed by the rollers. When it is necessary to prevent the device from tilting, the rollers can intervene in time and play a role according to the preset operation process. This clear operation sequence helps to improve deicing efficiency and reduce uncertainty during operation.

[0011] Furthermore, the mounting frame includes a first fixed plate and a second fixed plate, the first fixed plate is fixed with a second connecting plate, the second fixed plate is fixed with a first connecting plate, the second connecting plate is slidingly connected to the first connecting plate along the width direction, and a fourth linear drive component is provided between the second connecting plate and the first connecting plate for driving the two to slide relative to each other.

[0012] By adopting the aforementioned technical solution, the width direction mentioned above is the direction in which the two connecting plates move away from or closer to each other; by making the two connecting plates move away from or closer to each other, the de-icing device can adapt to cable lines with different spacings, thereby improving the versatility and adaptability of the device. Regardless of whether the cables have narrow spacing or wide spacing, the de-icing device can be installed thereon to perform effective de-icing operations.

[0013] Furthermore, a clearance groove is provided on the second connecting plate, and one end of the first connecting plate is inserted into the clearance groove; the fourth linear drive assembly includes a screw threadedly connected to the first connecting plate and a fourth motor driving the screw to rotate, and one end of the screw is rotationally connected to the first fixed plate.

[0014] With the above technical solution, the fourth linear drive assembly adopts a combination of a screw connected to the first connecting plate by thread and a fourth motor driving the screw to rotate. This design can achieve precise adjustment of the width of the deicing device. The rotation of the screw can be precisely controlled by the fourth motor, and the mounting frame can be adjusted to a suitable width according to actual needs, ensuring that the deicing device matches cables with different spacings, thereby improving the adaptability of the deicing device.

[0015] The fourth motor is a standard part, and since it does not need to generate excessive rotational force, a small motor can be used.

[0016] Furthermore, a first support and a second support are provided on the sides of the first fixing plate and the second fixing plate that are close to each other; and a roller is provided on the side of each first support that is away from the second support.

[0017] By adopting the above-mentioned technical solution, a first support, a second support and a roller are provided on the sides of the first fixing plate and the second fixing plate that are close to each other, so that the device can perform de-icing operations on two cables at the same time. This greatly improves the de-icing efficiency, especially when multiple cables need to be de-iced quickly, which can save a lot of time and labor costs. When de-icing operations are performed on both sides at the same time, the overall balance of the device is better. Since the structures and operations on both sides are symmetrical, they can check and balance each other during the de-icing process, reducing the shaking and instability of the device. At the same time, the rollers on both sides can also better support the device to prevent it from tilting, thereby improving the stability and safety of the de-icing operation.

[0018] Furthermore, the heights of the second connecting plate and the first connecting plate are higher than the first support and the second support.

[0019] With the above technical solution, this height setting makes it more convenient for operators to install, debug and maintain the device. Since the connecting plate is higher than the support, the operator can see and touch the support and related components below more clearly, making it easier to adjust, repair and replace parts.

[0020] Furthermore, the first linear drive assembly includes two first sliders, a first screw rod rotatably mounted on a mounting frame, and a first motor fixedly mounted on the mounting frame, the first motor is drivingly connected to the first screw rod, a first slide groove is provided on the mounting frame, the first screw rod is disposed in the first slide groove, two first sliders are slidably connected in the first slide groove, the first support and the second support are respectively fixed to the corresponding first sliders, the screw threads on both sides of the first screw rod have opposite spiral directions, and the two first sliders are respectively threadedly connected to both sides of the first screw rod.

[0021] By adopting the above-mentioned technical scheme, since the spiral directions of the threads on both sides of the first screw are opposite, when the motor drives the screw to rotate, the two first sliders will move in opposite directions at the same time, thereby driving the first support and the second support to approach or move away synchronously. This synchronization can ensure that the clamping force of the icebreaking wheel group on the cable is evenly distributed, and also reduces the control cost and the manufacturing cost of the whole machine. At the same time, the synchronous movement is also conducive to improving the working efficiency of the de-icing device and reducing the operation time. The first screw is set in the first slide groove of the mounting frame, and the two first sliders also slide in the slide groove. This structural design makes the first linear drive assembly occupy a small space and have a compact structure, which also further reduces the weight of the whole machine.

[0022] Furthermore, the second linear drive assembly includes a second motor installed on the first support and a second screw rod rotatably connected to the first support, and the second motor is drivingly connected to the second screw rod; a second slide groove is opened on the first support, and the second screw rod is arranged in the second slide groove, and a first guide rod parallel to the second screw rod is fixed in the second slide groove, and two second sliders are slidingly sleeved on the first guide rod, and the spiral directions of the threads on both sides of the second screw rod are opposite, and the two second sliders are respectively threadedly connected to the two sides of the second screw rod, and the two first ice-breaking wheels are respectively rotatably connected to the two second sliders.

[0023] With the above technical solution, since the threads on both sides of the second screw rod have opposite spiral directions, when the motor drives the screw rod to rotate, the two second sliders will move in opposite directions at the same time, thereby driving the two first ice-breaking wheels to move closer or farther away synchronously. This synchronization can ensure that the clamping force of the ice-breaking wheels on the cable is evenly distributed. At the same time, the setting of the first guide rod can increase the stability of the slider movement, prevent the slider from shaking or deviating during movement, and further improve the stability and reliability of the deicing device.

[0024] Furthermore, the third linear drive assembly includes a third screw rod rotatably connected to the second support and a third motor installed on the second support, and the third motor is drivingly connected to the third screw rod; a third slide groove is opened on the second support, and the third screw rod is arranged in the third slide groove, and a second guide rod parallel to the third screw rod is fixed in the third slide groove, and two third sliding blocks are slidingly sleeved on the second guide rod, and the spiral directions of the threads on both sides of the third screw rod are opposite, and the two third sliding blocks are respectively threadedly connected to the two sides of the third screw rod, and the two third sliding blocks are respectively rotatably connected to the two second ice-breaking wheels, and the rotation drive assembly is drivingly connected to one of the second ice-breaking wheels.

[0025] With the above technical solution, the third linear drive assembly drives the third screw rod through the third motor, and can accurately adjust the spacing between the two second ice-breaking wheels. The screw rod transmission has the characteristics of high precision, and can achieve fine adjustment of the spacing between the ice-breaking wheels to adapt to cables of different diameters and ice layers of different thicknesses. This ensures that the ice-breaking wheels exert appropriate pressure on the cable ice and improves the deicing effect.

[0026] A method for deicing a power transmission line, comprising the above-mentioned deicing device, further comprising the following steps: Step 100, placing the mounting frame on the cable and passing the cable between the two first ice-breaking wheels and between the two second ice-breaking wheels, Step 200, the two first ice-breaking wheels are brought close to each other, and the two second ice-breaking wheels are brought close to each other, so that the ice layer on the cable is cut off. Step 300, the first support and the second support are brought close to each other, and the ice layer between the first ice-breaking wheel group and the second ice-breaking wheel group is crushed and broken; Step 400, after that, the two first ice-breaking wheels are moved away from each other, the rollers are in contact with the ice layer, and then the mounting frame is moved along the cable toward the first ice-breaking wheel group. Step 500, then the two first ice-breaking wheels are brought close to each other to break the ice layer, and the first support and the second support are brought close to each other again; Step 600: According to this, the first ice-breaking wheel group and the second ice-breaking wheel group break the ice layer on the cable section by section.

[0027] It can be seen that the de-icing device, through the synergistic effect of the first ice-breaking wheel group and the second ice-breaking wheel group, applies positive pressure to the ice layer on the cable to break it and fall it off during the first ice-breaking. The second ice-breaking is the rolling pressure generated by the first ice-breaking wheel group and the second ice-breaking wheel group moving away from each other, so that the ice layer between the first ice-breaking wheel group and the second ice-breaking wheel group breaks and falls off. The third ice-breaking is that when the rotating second ice-breaking wheel moves forward, the thin ice layer remaining on the cable is rolled and crushed, which can effectively and thoroughly remove the ice layer on the cable, achieve more thorough de-icing, and improve the de-icing efficiency.

[0032] The following specific embodiments are used to describe the technical solution of the present application in detail. The following specific embodiments can be combined or replaced with each other according to actual conditions, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0033] like Figures 1 to 7As shown, the present application provides a power transmission line deicing device, including a mounting frame, a roller 6, a first ice-breaking wheel group and a second ice-breaking wheel group, the mounting frame is horizontally slidably provided with a first support 7 and a second support 9, the roller 6 is rotatably provided at the upper part of the mounting frame and is located at a side of the first support 7 away from the second support 9, and the mounting frame is provided with a first linear drive component that drives the first support 7 and the second support 9 to move closer to or away from each other; The first ice-breaking wheel assembly includes two first ice-breaking wheels 5 that move up and down on a first support 7, and a second linear drive assembly that drives the two first ice-breaking wheels 5 to move toward or away from each other; The second ice-breaking wheel assembly includes two second ice-breaking wheels 10 that move up and down on the second support 9, a third linear drive component that drives the two second ice-breaking wheels 10 to move closer to or away from each other, and a rotation drive component that drives at least one second ice-breaking wheel 10 to rotate.

[0034] After adopting the above technical scheme, the working process of the de-icing device is as follows: first, the second linear drive component controls the two first ice-breaking wheels 5 to move away from each other, and the third linear drive component controls the two second ice-breaking wheels 10 to move away from each other, and the two cables 12 that need to be de-iced are placed in the clamping space between the corresponding first ice-breaking wheel group and the second ice-breaking wheel group, and then the second linear drive component and the third linear drive component control the corresponding wheel groups to move closer to each other, and generate positive pressure on the ice on the clamped cables 12 until the ice layer breaks, so that the two ice-breaking wheels are close together, and then the first linear drive component controls the first ice-breaking wheel group and the second ice-breaking wheel group to move closer to each other, and the ice between the two groups of wheel groups is broken. At this time, the roller 6 can gradually descend to the cable 12 or the ice cover to prevent the entire de-icing device from tilting too much. Then the first linear drive component controls the first ice-breaking wheel group and the second ice-breaking wheel group to move away from each other to the initial position, and then the second linear drive component controls the first ice-breaking wheel group to move away from each other, so that the roller 6 directly rests on the cable 12 or the ice cover. Finally, the rotation drive component controls the two second ice-breaking wheels 10 to roll along the extension direction of the cable 12. During the rolling process, the two second ice-breaking wheels 10 can crush the ice layer that has not been completely broken again to achieve more thorough de-icing. After the de-icing device moves to the next part of the cable 12 that needs to be de-iced, the next de-icing operation of the ice cover is carried out.

[0035] The present application has the following advantages: It can be seen that the de-icing device, through the synergistic effect of the first ice-breaking wheel group and the second ice-breaking wheel group, first applies positive pressure to the ice layer 4 on the cable 12 to break it, then performs a breaking operation, and finally rolls and crushes it through the rotating second ice-breaking wheel 10, which can effectively and thoroughly remove the ice layer 4 on the cable 12, achieve more thorough de-icing, and improve de-icing efficiency.

[0036] Compared with the traditional deicing robot, the present device only uses a small number of ice-breaking wheels and motors, as well as some moving components, while ensuring the deicing effect, thereby reducing the overall cost. Moreover, compared with using a powerful power device to push and remove the ice layer 4, the present device uses positive pressure on the ice layer 4, and only requires a small force to crush the ice surface. While the present device is low in cost, through a reasonable structural design, it avoids excessive pressure on the cable 12, thereby improving the practicality and economy of the device.

[0037] Preferably, when the first ice-breaking wheel group and the second ice-breaking wheel group are close to each other, the distance moved by the first ice-breaking wheel group is greater than that of the second ice-breaking wheel group, so that the roller 6 can lean against the cable 12 more stably, preventing the device from shaking back and forth on both sides when breaking the ice on this part.

[0038] The gap between the same group of ice-breaking wheels is matched with the diameter of the cable 12, or slightly smaller than the diameter of the cable 12, so as to ensure that the ice layer on the cable 12 can be completely crushed and the two second ice-breaking wheels 10 can move more stably on the cable 12.

[0039] Furthermore, when the two first ice-breaking wheels 5 clamp the cable 12 , the height of the roller 6 is higher than the height of the first ice-breaking wheel 5 located above.

[0040] With the above technical solution, this height setting makes the operation sequence of the device more reasonable. When deicing, the ice-breaking wheel group can squeeze and break the ice layer 4 with all its strength without being interfered by the roller 6. When it is necessary to prevent the device from tilting, the roller 6 can intervene in time and play a role according to the preset operation process. This clear operation sequence helps to improve the deicing efficiency and reduce the uncertainty during the operation process.

[0041] Furthermore, the mounting frame includes a first fixed plate 1 and a second fixed plate 2, a second connecting plate 11 is fixed on the first fixed plate 1, a first connecting plate 8 is fixed on the second fixed plate 2, the second connecting plate 11 is slidably connected to the first connecting plate 8 along the width direction, and a fourth linear drive component is provided between the second connecting plate 11 and the first connecting plate 8 for driving the two to slide relative to each other.

[0042] By adopting the aforementioned technical solution, the width direction mentioned above is the direction in which the two connecting plates move away from or closer to each other; by making the two connecting plates move away from or closer to each other, the de-icing device can adapt to cable 12 lines with different spacings, thereby improving the versatility and adaptability of the device. Regardless of whether the cables 12 have a narrow spacing or a wide spacing, the de-icing device can be installed thereon to perform effective de-icing operations.

[0043] Furthermore, a clearance groove 15 is provided on the second connecting plate 11, and one end of the first connecting plate 8 is inserted into the clearance groove 15; the fourth linear drive assembly includes a screw 14 threadedly connected to the first connecting plate 8 and a fourth motor 3 driving the screw 14 to rotate, and one end of the screw 14 is rotationally connected to the first fixed plate 1.

[0044] With the above technical solution, the fourth linear drive assembly adopts a combination of a screw 14 threadedly connected to the first connecting plate 8 and a fourth motor 3 driving the screw 14 to rotate. This design can achieve precise adjustment of the width of the deicing device. The rotation of the screw 14 can be precisely controlled by the fourth motor 3, and the mounting frame can be adjusted to a suitable width according to actual needs, ensuring that the deicing device matches the cables 12 with different spacings, thereby improving the adaptability of the deicing device.

[0045] Specifically, the fourth motor 3 is a standard component, and since it is not necessary to generate excessive rotational force, a small motor can be used.

[0046] Furthermore, a first support 7 and a second support 9 are provided on the sides of the first fixing plate 1 and the second fixing plate 2 that are close to each other; and a roller 6 is provided on the side of each first support 7 that is away from the second support 9 .

[0047] By adopting the above-mentioned technical scheme, a first support 7, a second support 9 and a roller 6 are provided on the sides of the first fixed plate 1 and the second fixed plate 2 that are close to each other, so that the device can de-ice two cables 12 at the same time, which greatly improves the de-icing efficiency. Especially when multiple cables 12 need to be de-iced quickly, it can save a lot of time and labor costs. When de-icing operations are performed on both sides at the same time, the overall balance of the device is better. Since the structures and operations on both sides are symmetrical, they can check and balance each other during the de-icing process, reducing the shaking and instability of the device. At the same time, the rollers 6 on both sides can also better support the device to prevent it from tilting, thereby improving the stability and safety of the de-icing operation.

[0048] Furthermore, the heights of the second connecting plate 11 and the first connecting plate 8 are higher than the first support 7 and the second support 9 .

[0049] With the above technical solution, this height setting makes it more convenient for operators to install, debug and maintain the device. Since the connecting plate is higher than the support, the operator can see and touch the support and related components below more clearly, making it easier to adjust, repair and replace parts.

[0050] Furthermore, the first linear drive assembly includes two first sliders 18, a first screw rod 19 rotatably mounted on a mounting frame, and a first motor 16 fixedly mounted on the mounting frame. The first motor 16 is drivingly connected to the first screw rod 19. A first slide groove 17 is provided on the mounting frame. The first screw rod 19 is disposed in the first slide groove 17. The two first sliders 18 are slidably connected in the first slide groove 17. The first support 7 and the second support 9 are respectively fixed to the corresponding first sliders 18. The screw threads on both sides of the first screw rod 19 have opposite spiral directions. The two first sliders 18 are respectively threadedly connected to both sides of the first screw rod 19.

[0051] By adopting the above-mentioned technical scheme, since the spiral directions of the threads on both sides of the first screw rod 19 are opposite, when the motor drives the screw rod to rotate, the two first sliders 18 will move in opposite directions at the same time, thereby driving the first support 7 and the second support 9 to approach or move away synchronously. This synchronization can ensure that the clamping force of the ice-breaking wheel group on the cable 12 is evenly distributed, and also reduces the control cost and the manufacturing cost of the whole machine. At the same time, the synchronous movement is also conducive to improving the working efficiency of the de-icing device and reducing the operation time. The first screw rod 19 is set in the first slide groove 17 of the mounting frame, and the two first sliders 18 also slide in the slide groove. This structural design makes the first linear drive component occupy a small space and have a compact structure, which also further reduces the weight of the whole machine.

[0052] Furthermore, the second linear drive assembly includes a second motor 31 installed on the first support 7 and a second screw rod 32 rotatably connected to the first support 7, and the second motor 31 is drivingly connected to the second screw rod 32; a second slide groove 21 is opened on the first support 7, and the second screw rod 32 is arranged in the second slide groove 21, and a first guide rod 22 parallel to the second screw rod 32 is fixed in the second slide groove 21, and two second sliders 33 are slidably sleeved on the first guide rod 22, and the screw threads on both sides of the second screw rod 32 have opposite spiral directions, and the two second sliders 33 are respectively threadedly connected to the two sides of the second screw rod 32, and the two first ice-breaking wheels 5 are respectively rotatably connected to the two second sliders 33.

[0053] With the above technical solution, since the screw threads on both sides of the second screw rod 32 have opposite spiral directions, when the motor drives the screw rod to rotate, the two second sliders 33 will move in opposite directions at the same time, thereby driving the two first ice-breaking wheels 5 to move closer or farther away synchronously. This synchronization can ensure that the clamping force of the ice-breaking wheels on the cable 12 is evenly distributed. At the same time, the provision of the first guide rod 22 can increase the stability of the slider movement, prevent the slider from shaking or deflecting during the movement, and further improve the stability and reliability of the deicing device.

[0054] Furthermore, the third linear drive assembly includes a third screw rod 25 rotatably connected to the second support 9 and a third motor 27 installed on the second support 9, and the third motor 27 is drivingly connected to the third screw rod 25; a third slide groove 24 is opened on the second support 9, and the third screw rod 25 is arranged in the third slide groove 24, and a second guide rod 26 parallel to the third screw rod 25 is fixed in the third slide groove 24, and two third sliders 28 are slidingly sleeved on the second guide rod 26, and the screw threads on both sides of the third screw rod 25 have opposite spiral directions, and the two third sliders 28 are respectively threadedly connected to the two sides of the third screw rod 25, and the two third sliders 28 are respectively rotatably connected to the two second ice-breaking wheels 10, and the rotation drive assembly is drivingly connected to one of the second ice-breaking wheels 10.

[0055] By adopting the above technical solution, the third linear drive assembly drives the third screw 25 through the third motor 27, and can accurately adjust the distance between the two second ice-breaking wheels 10. The screw drive has the characteristics of high precision, and can achieve fine adjustment of the ice-breaking wheel spacing to adapt to cables 12 of different diameters and ice layers of different thicknesses. This ensures that the ice-breaking wheels exert appropriate pressure on the ice covering the cable 12, thereby improving the deicing effect.

[0056] A method for deicing a power transmission line, comprising the above-mentioned deicing device, further comprising the following steps: Step 100, placing the mounting frame on the cable 12 and passing the cable 12 between the two first ice-breaking wheels 5 and between the two second ice-breaking wheels 10, Step 200, the two first ice-breaking wheels 5 are brought close to each other, and the two second ice-breaking wheels 10 are brought close to each other, and the ice layer 4 on the cable 12 is cut off. Step 300, the first support 7 and the second support 9 are brought close to each other, and the ice layer 4 between the first ice-breaking wheel group and the second ice-breaking wheel group is crushed and broken; Step 400, the two first ice-breaking wheels 5 are then moved away from each other, the roller 6 contacts the ice layer 4, and then the mounting frame is moved along the cable 12 toward the first ice-breaking wheel group. Step 500, then the two first ice-breaking wheels 5 are brought close to each other to cut off the ice layer 4, and the first support 7 and the second support 9 are brought close to each other again; Step 600, accordingly, the first ice-breaking wheel group and the second ice-breaking wheel group break the ice layer 4 on the cable 12 section by section.

[0057] It can be seen that the de-icing device, through the synergistic effect of the first ice-breaking wheel group and the second ice-breaking wheel group, the first ice-breaking is to apply positive pressure to the ice layer 4 on the cable 12 to make it break and fall off, the second ice-breaking is the rolling pressure generated by the first ice-breaking wheel group and the second ice-breaking wheel group moving away from each other, so that the ice layer 4 between the first ice-breaking wheel group and the second ice-breaking wheel group breaks and falls off, and the third ice-breaking is to roll and crush the thin ice layer remaining on the cable 12 when the rotating second ice-breaking wheel 10 moves forward, which can effectively and thoroughly remove the ice layer 4 on the cable 12, achieve more thorough de-icing, and improve de-icing efficiency.
