Description

Technical Field

[0001] This invention relates to the field of cable maintenance technology, and in particular to a cable de-icing device. Background Technology

[0002] During cold waves or frost disasters, overhead power lines are affected by icing, which consists of cylindrical layers of ice adhering to the lines. Icing can lead to problems such as line breakage, tower collapse, and reduced insulation performance, resulting in power outages and widespread blackouts. This seriously threatens the safe and stable operation of the power system.

[0003] Maintaining power lines and removing ice requires significant manpower and financial resources for inspection and de-icing. Existing de-icing equipment mainly falls into two categories: thermal melting and mechanical vibration. Thermal melting lowers the melting point of ice through high temperatures or chemical agents, but this method can damage conductors and is inefficient. Mechanical vibration utilizes the impact force generated by a power source to vibrate and break down the ice layer; common power sources include gunpowder and electric detonators. However, the use of gunpowder has many limitations, such as long intervals between uses, strict regulations, and inconvenience in carrying, resulting in poor usability. Meanwhile, electric detonators, due to their complex structure, are easily affected by impacts, leading to less than ideal de-icing results.

[0004] Therefore, there is an urgent need to research a cable de-icing device to improve ease of use and de-icing efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a cable de-icing device to improve ease of use and de-icing efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Cable de-icing device, including:

[0008] frame;

[0009] A walking assembly is provided on the frame and is used to abut against the cable and can move along the extension direction of the cable;

[0010] The de-icing assembly includes a de-icing bracket, a de-icing drive, an upper de-icing component, and a lower de-icing component. The de-icing bracket is movably mounted on the frame in a vertical direction. The de-icing drive is mounted on the de-icing bracket, and its output end can reciprocate in a vertical direction. The lower de-icing component is fixed to the lower end of the de-icing bracket. The upper de-icing component is located above the lower de-icing component and is drively connected to the output end of the de-icing drive. During the downward movement of the output end of the de-icing drive, the upper de-icing component is first driven to descend to abut against the upper side of the cylindrical ice layer outside the cable, and then the de-icing bracket is driven to rise to drive the lower de-icing component to rise and abut against the lower side of the cylindrical ice layer. Ultimately, the upper de-icing component and the lower de-icing component both extend at least partially into the cylindrical ice layer.

[0011] As an optional technical solution for a cable de-icing device, the de-icing bracket includes an upper fixed plate, a lower fixed plate, and a first guide member. The first guide member extends vertically, with its upper end connected to the upper fixed plate and its lower end connected to the lower fixed plate. The frame is provided with a guide hole extending vertically, and the first guide member passes through the guide hole and can slide relative to the frame in the vertical direction. The upper de-icing component is slidably disposed on the first guide member.

[0012] As an optional technical solution for a cable de-icing device, the upper de-icing component includes an upper mounting plate and an upper ice blade mounted on the upper mounting plate. The upper ice blade is parallel to the extension direction of the cable. The upper mounting plate is provided with a mounting hole extending in a vertical direction. The first guide member passes through the mounting hole. The output end of the de-icing drive member is connected to the upper mounting plate in a transmission manner. The upper mounting plate can slide relative to the first guide member.

[0013] And / or,

[0014] The lower de-icing component includes a lower mounting plate and a lower ice blade mounted on the lower mounting plate. The lower ice blade is parallel to the extension direction of the cable, and the lower mounting plate is fixedly connected to the lower fixing plate.

[0015] As an optional technical solution for a cable de-icing device, the upper de-icing component includes one upper ice blade, and the lower de-icing component includes two lower ice blades. When the upper ice blade partially extends into the cylindrical ice layer and the lower ice blade partially extends into the cylindrical ice layer, the upper ice blade and the lower ice blade are arranged around the outer periphery of the cable.

[0016] As an optional technical solution for cable de-icing devices, the upper ice blade has at least a chamfer at its front end; and / or,

[0017] The lower ice skate has a chamfer at least at its front end.

[0018] As an optional technical solution for a cable de-icing device, the de-icing drive is a rotary drive, and the de-icing assembly includes a first lead screw and a drive nut. The first lead screw is rotatably mounted on the de-icing bracket and is connected to the output end of the rotary drive. The drive nut is threadedly engaged with the first lead screw and is connected to the upper de-icing component.

[0019] As an optional technical solution for cable de-icing devices, the cable de-icing device further includes a cleaning assembly, which includes a cleaning housing and a cleaning component. The cleaning end of the cleaning component is used to abut against the upper side of the cable. Along the cleaning direction, the cleaning component can reciprocate relative to the cleaning housing so that the cleaning end scrapes the upper side of the cable. The cleaning direction and the extension direction of the cable are set at an acute angle.

[0020] As an optional technical solution for cable de-icing devices, the cleaning component is sheet-shaped, the length of the cleaning component is greater than or equal to the diameter of the cable, and the cleaning component is set at an acute angle to the axis of the cable.

[0021] As an optional technical solution for a cable de-icing device, the walking component includes a first roller and a second roller, which are arranged vertically at intervals and used to clamp the cable on both sides. At least one of the first roller and the second roller can rotate actively, and the second roller can move closer to or away from the first roller.

[0022] As an optional technical solution for a cable de-icing device, there are two first rollers, which are spaced apart along the extension direction of the cable. Along the extension direction of the cable, the second roller is located between the two first rollers. When the second roller is close to the first roller, the distance between the second roller and the first roller in the height direction is less than the diameter of the cable.

[0023] The beneficial effects of this invention are as follows:

[0024] This invention provides a cable de-icing device, which includes a frame, a traveling assembly, and a de-icing assembly. The traveling assembly travels along the cable. The de-icing assembly includes a de-icing bracket movably mounted vertically on the frame. A de-icing drive is mounted on the de-icing bracket. An upper de-icing component is located at the output end of the drive, and a lower de-icing component is located at the lower end of the bracket. During the operation of the drive, the upper de-icing component is first driven to descend to contact the upper side of the cylindrical ice layer outside the cable, and then the entire de-icing bracket is driven to rise, thereby causing the lower de-icing component to rise and contact the cable. The upper and lower de-icing components are positioned below the cylindrical ice layer, allowing at least a portion of each component to extend into the ice layer. In this state, as the traveling assembly moves along the cable, the upper and lower de-icing components slice through the ice layer. Due to the properties of ice, the ice layer breaks apart instantly upon slicing, allowing it to fall off the cable and complete the de-icing process. Since the traveling speed is the same as the de-icing speed, the de-icing efficiency is high, and the process does not require blasting, saving energy. Furthermore, the de-icing process does not require explosives, making it more convenient to use. Finally, due to the sequential movement of the upper and lower de-icing components, they can automatically align with the cable as the center. After the cable is clamped by the upper and lower de-icing components, it will not bend regardless of its diameter. This ensures that the central axis of cables of different diameters passes through the middle position between the upper and lower de-icing components, preventing scratches on the cable's surface during movement. No separate adjustments are needed when dealing with cables of different diameters, thus improving de-icing efficiency. Attached Figure Description

[0041] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0042] like Figures 1 to 7 As shown, this embodiment provides a cable de-icing device to improve the de-icing efficiency and ease of use of the cable 1000. The cable de-icing device includes a frame 100, a traveling assembly 200, and a lower de-icing assembly 300. The traveling assembly 300 is mounted on the frame 100 and is used to abut against the cable 1000 and can travel along the extension direction of the cable 1000. The de-icing assembly 300 includes a de-icing bracket 310, a de-icing drive 320, an upper de-icing component 330, and a lower de-icing component 340. The de-icing bracket 310 is movably mounted on the frame 100 in the vertical direction. The de-icing drive 320 is mounted on the de-icing bracket 310, and the output end of the de-icing drive 320 can reciprocate in the vertical direction. The lower de-icing component 340 is fixedly mounted. At the lower end of the de-icing bracket 310, the upper de-icing component 330 is located above the lower de-icing component 340 and is connected to the output end of the de-icing drive component 320. During the downward movement of the output end of the de-icing drive component 320, the upper de-icing component 330 is first driven to descend to abut against the upper side of the cylindrical ice layer 2000 outside the cable 1000, and then the de-icing bracket 310 is driven to rise to drive the lower de-icing component 340 to rise and abut against the lower side of the cylindrical ice layer 2000. Finally, the upper de-icing component 330 extends into the cylindrical ice layer 2000 at least partially, and the lower de-icing component 340 extends into the cylindrical ice layer 2000 at least partially.

[0043] In this state, as the walking component 200 moves along the cable 1000, the upper de-icing component 330 and the lower de-icing component 340 can cut open the cylindrical ice layer 2000. Due to the brittle nature of ice, the cylindrical ice layer 2000 breaks apart at the moment it is cut open, thus falling off the cable 1000 and completing the de-icing work. Since the walking speed is the de-icing speed, the de-icing efficiency is high, and the de-icing process does not require blasting, saving energy. At the same time, the de-icing process does not require gunpowder, making it more convenient to use. Finally, with the help of the movable de-icing bracket 310, as the upper de-icing component 330 and the lower de-icing component 340 approach each other, automatic centering of the upper de-icing component 330 and the lower de-icing component 340 around the cable 1000 is achieved. After the cable 1000 is clamped by the upper de-icing component 330 and the lower de-icing component 340, the cable 1000 will not bend regardless of its diameter. This ensures that the central axis of cables 1000 of different diameters passes through the middle position between the upper de-icing component 330 and the lower de-icing component 340, thereby preventing scratches on the surface of the cable 1000 during movement. When dealing with cables 1000 of different diameters, no separate adjustment is required, improving de-icing efficiency. It should be noted that when the upper de-icing component 330 and the lower de-icing component 340 clamp the cable 1000, the distance between the upper de-icing component 330 and the lower de-icing component 340 is greater than the diameter of the cable 1000.

[0044] Combination Figures 2 to 4 As shown, in some embodiments, the de-icing bracket 310 includes an upper fixing plate 311, a lower fixing plate 312, and a first guide member 313. The first guide member 313 extends vertically, with its upper end connected to the upper fixing plate 311 and its lower end connected to the lower fixing plate 312. The frame 100 has a guide hole extending vertically, through which the first guide member 313 passes and can slide relative to the frame 100 in the vertical direction. The first guide member 313 serves as a connector between the upper fixing plate 311 and the lower fixing plate 312, a sliding connection between the de-icing bracket 310 and the frame 100, and a sliding carrier for the upper de-icing component 330. This ingenious three-in-one design helps reduce the production cost of the de-icing bracket 310.

[0045] To ensure smooth cutting of the cylindrical ice layer 2000, the upper de-icing component 330 includes an upper mounting plate 331 and an upper ice blade 332 mounted on the upper mounting plate 331. The upper ice blade 332 is parallel to the extension direction of the cable 1000. The upper mounting plate 331 has a mounting hole extending vertically, and a first guide member 313 passes through the mounting hole. The output end of the de-icing drive component 320 is connected to the upper mounting plate 331, and the upper mounting plate 331 can slide relative to the first guide member 313. This arrangement allows the upper ice blade 332 to cut a gap on the upper side of the cylindrical ice layer 2000 during the movement of the frame 100.

[0046] The lower de-icing component 340 includes a lower mounting plate 341 and a lower ice blade 342 mounted on the lower mounting plate 341. The lower ice blade 342 is parallel to the extension direction of the cable 1000, and the lower mounting plate 341 is fixedly connected to the lower fixing plate 312. This arrangement allows the lower ice blade 342 to cut a gap on the underside of the cylindrical ice layer 2000 during the movement of the frame 100. It should be noted that the cutting edges of the upper ice blade 332 and the lower ice blade 342 are not sharp enough to cut the cable 1000.

[0047] To effectively break up the cylindrical ice layer 2000, the upper de-icing component 330 includes an upper ice blade 332, and the lower de-icing component 340 includes two lower ice blades 342. The upper ice blade 332 partially extends into the cylindrical ice layer 2000, and the lower ice blades 342 partially extend into the cylindrical ice layer 2000. The upper ice blade 332 and lower ice blades 342 are arranged around the outer periphery of the cable 1000. The two lower ice blades 342 are spaced apart in the left-right direction. The three ice blades simultaneously cut the cylindrical ice layer 2000, and the cutting points are distributed around the outer periphery of the cable 1000, thereby dividing the cylindrical ice layer 2000 into three smaller ice blocks that are separated into non-circular structures. This effectively reduces the adhesion area between the ice blocks and the cable 1000, making it easier for the ice blocks to slide off the cable 1000 under gravity. In some embodiments, the angle between the two lower blades 342 is 40° to 70°, and the upper blade 332 is located directly above the cylindrical ice layer 2000, with the plane of the upper blade 332 passing through the axis of the cable 1000. Exemplarily, the angle between the two lower blades 342 is 50°, and the included angle between the upper blade 332 and any one of the lower blades 342 is 155°. In some embodiments, the included angle α between the upper blade 332 and any two of the two lower blades 342 is 60°.

[0048] In some embodiments, the planes on which the upper blade 332 and the lower blade 342 are located are parallel to the axis of the cable 1000 and also parallel to the forward direction of the frame 100, so that the blades can smoothly cut through the cylindrical ice layer 2000.

[0049] During the movement of the frame 100, to improve the cutting efficiency of the upper blade 332, at least the front end of the upper blade 332 is chamfered. Preferably, the blade of the upper blade 332 is arc-shaped and convex downwards. To improve the cutting efficiency of the lower blade 342, at least the front end of the lower blade 342 is chamfered. In some embodiments, the blade of the lower blade 342 is arc-shaped and convexes towards the axis of the cable 1000. In other words, the blade of the upper blade 332 is arc-shaped, the middle part of the blade is inserted into the cylindrical ice layer 2000, and the two ends of the blade in the front-rear direction are outside the cylindrical ice layer 2000. Similarly, the blade of the lower blade 342 is curved, with the middle part of the blade inserted into the cylindrical ice layer 2000, and the two ends of the blade in the front-to-back direction outside the cylindrical ice layer 2000, thus serving a guiding function. During the movement of the cable de-icing device, the cylindrical ice layer 2000 is guided between the upper blade 332 and the lower blade 342 for easy cutting. In other embodiments, both the upper blade 332 and the lower blade 342 can have a chamfered front end, as long as it ensures that the cylindrical ice layer 2000 can be smoothly guided between the upper blade 332 and the lower blade 342 during the movement of the cable de-icing device.

[0050] In some embodiments, the surface of the lower mounting plate 341 on which the lower blade 342 is mounted is an inclined surface, tilted downwards from front to back, so that the ice fragments falling onto the lower mounting plate 341 can slide backwards and avoid accumulating on the lower mounting plate 341, thus ensuring the smoothness of the lower blade 342 cutting the cylindrical ice layer 2000.

[0051] In some embodiments, the lower mounting plate 341 is provided with a clearance hole (not shown in the figure), which is located between the two lower ice blades 342 so that the ice fragments falling onto the lower mounting plate 341 can pass through the clearance hole and fall to the ground, avoiding accumulation on the lower mounting plate 341 and ensuring the smoothness of the lower ice blades 342 cutting the cylindrical ice layer 2000.

[0052] In some embodiments, the lower mounting plate 341 is provided with a clearance hole (not shown in the figure), which is located between the two lower ice blades 342. The surface of the lower mounting plate 341 on which the lower ice blades 342 are mounted is an inclined surface, which is inclined downward from front to back and downward from both sides to the middle, so that the ice fragments falling onto the lower mounting plate 341 can pass through the clearance hole to fall to the ground or slide backward, so as to avoid accumulating on the lower mounting plate 341 and ensure the smoothness of the lower ice blades 342 cutting the cylindrical ice layer 2000.

[0053] To ensure the stability of the sliding, in some embodiments, there are two first guide members 313. The first guide members 313 are rod-shaped and extend in the vertical direction. The two first guide members 313 are spaced apart. The frame 100 is provided with two guide holes, and the two first guide members 313 are respectively inserted into the corresponding guide holes.

[0054] In some embodiments, the de-icing drive 320 is a rotary drive, and the de-icing assembly 300 includes a first lead screw 350 and a drive nut. The first lead screw 350 is rotatably mounted on the de-icing bracket 310 and is connected to the output end of the rotary drive. The drive nut and the first lead screw 350 are threadedly engaged and connected to the upper de-icing component 330. The rotary drive is a servo motor. The above configuration enables the driving function of the upper de-icing component 330 and has a self-locking function to prevent the distance between the upper de-icing component 330 and the lower de-icing component 340 from changing during the movement of the frame 100, thereby ensuring the de-icing effect. Of course, in other embodiments, the de-icing drive 320 can be a push rod motor, wherein the push rod motor is mounted on the upper fixed plate 311.

[0055] Combination Figure 1 and Figure 5 As shown, considering that some ice or ice residue remains on the cable 1000, the cable de-icing device further includes a cleaning component 400 to clean it thoroughly. The cleaning component 400 includes a cleaning housing 410 and a cleaning element 420. The cleaning end of the cleaning element 420 abuts against the upper side of the cable 1000. Along the cleaning direction X, the cleaning element 420 can reciprocate relative to the cleaning housing 410, allowing the cleaning end to scrape the upper side of the cable 1000. The angle β between the cleaning direction X and the extension direction of the cable 1000 is an acute angle. This arrangement allows the cleaning element 420 to press the cable 1000 downwards during movement, ensuring good contact between the cleaning end and the cable 1000 and effectively improving the cleaning effect.

[0056] In some embodiments, the cleaning member 420 is sheet-shaped, and its length is greater than or equal to the diameter of the cable 1000. The angle between the cleaning member 420 and the cable 1000 is an acute angle. This structure allows the cleaning member 420 to scoop up ice fragments as it moves backward, allowing them to slide off the cable 1000. The opening of the angle between the cleaning member 420 and the cable 1000 faces forward.

[0057] Considering that the backward movement of the cleaning component 420 is an effective cleaning process, in order to ensure the continuity of cleaning, in some embodiments, the moving speed of the cleaning component 420 is greater than or equal to twice the moving speed of the frame 100, thereby ensuring that the cleaning component 420 can clean the cable 1000 by shoveling.

[0058] In some embodiments, the cleaning component 420 moves between a first position and a second position, wherein the cleaning component 420 in the first position contacts the cable 1000, and the cleaning component 420 in the second position is separated from the cable 1000. This arrangement causes the cleaning component 420 to vibrate momentarily upon contact with the cable 1000, thereby shaking off the ice blocks, thus giving the cleaning component 420 both vibration and scooping cleaning effects.

[0059] Regarding the drive structure, in some embodiments, the cleaning assembly 400 further includes a cleaning drive component 430, a cam 440, a crankshaft 450, and a slider 460. The cleaning housing 410 is connected to the frame 100. The cleaning drive component 430 is disposed in the cleaning housing 410. The cam 440 is disposed at the output end of the cleaning drive component 430. The slider 460 is slidably disposed on the second guide component 470 of the cleaning housing 410 along the cleaning direction X. The two ends of the crankshaft 450 are respectively hinged to the cam 440 and the slider 460. The cleaning component 420 is fixedly connected to the slider 460. The above structure makes the reciprocating motion of the cleaning component 420 easy to realize and the running speed easy to adjust.

[0060] Combination Figure 1 and Figure 6 As shown, in some embodiments, the walking assembly 200 includes a first roller 210 and a second roller 220, which are arranged vertically at intervals and used to clamp the cable 1000 on both sides. At least one of the first roller 210 and the second roller 220 can rotate actively, and the second roller 220 can move closer to or away from the first roller 210. Exemplarily, the first roller 210 can rotate actively. The walking assembly 200 also includes a walking drive component, which is disposed on the frame 100. The first roller 210 and the output end of the walking drive component are connected in a transmission manner.

[0061] The first roller 210 is located above the second roller 220. The walking assembly 200 also includes a lifting drive 221, a second lead screw 224, and a lifting block 222. The lifting drive 221 is mounted on the frame 100. The second lead screw 224 is rotatably mounted on the frame 100 and is connected to the lifting drive 221. The lifting block 222 has a screw hole and a third guide 223 is slidably mounted on the frame 100 in the vertical direction. The second roller 220 is rotatably mounted on the lifting block 222. The second lead screw 224 is threadedly engaged with the screw hole of the lifting block 222.

[0062] Two first rollers 210 are provided, spaced apart along the extension direction of the cable 1000. A second roller 220 is located between the two first rollers 210 along the extension direction of the cable 1000. When the second roller 220 is close to the first roller 210, the distance between the second roller 220 and the first roller 210 in the vertical direction is less than the diameter of the cable 1000. This arrangement causes the cable 1000 to bend after being clamped by the second roller 220 and the first roller 210, thus ensuring that the first roller 210 and the second roller 220 clamp the cable 1000 tightly and maintain friction. Furthermore, the bending of the cable 1000 causes the cylindrical ice layer 2000 on top to break, thereby achieving a de-icing effect.

[0063] In some embodiments, both first rollers 210 can rotate actively, which increases the driving power and helps to avoid slippage, thus improving the reliability of walking.

[0064] By combining the de-icing component 300, the walking component 200, and the cleaning component 400, the cable de-icing device achieves three-stage de-icing work at the front, middle, and rear, thus effectively ensuring the de-icing effect of the cable 1000.

[0065] To prevent misalignment between the cable 1000 and the first roller 210, in some embodiments, the first roller 210 has a circumferential annular groove in which the cable 1000 can be located. The second roller 220 also has an annular groove, and the lower side of the cable 1000 is located in the annular groove of the second roller 220.

[0066] To facilitate the placement of the cable de-icing device on the cable 1000, a drone can be used for operation. A lifting device 110 is installed on the top of the frame 100, and a hook is installed below the drone to hook the lifting device 110, thereby lifting the cable de-icing device to the cable 1000 and placing the cable 1000 between the first roller 210 and the second roller 220.

[0067] Combination Figure 7 As shown, to facilitate the placement of the cable 1000 between the first roller 210 and the second roller 220, in some embodiments, a guide frame 120 is provided on the frame 100. The guide frame 120 is inclined from top to bottom away from the frame 100, and the connection between the guide frame 120 and the frame 100 is located below the first roller 210 and above the second roller 220. The folding structure between the guide frame 120 and the frame 100 facilitates the downward placement of the cable de-icing device, allowing the cable 1000 to enter between the first roller 210 and the second roller 220 along the guide frame 120.

[0068] In some embodiments, to ensure placement accuracy, a camera 130 is provided at the lower end of the guide frame 120 to transmit the captured images to the operation interface for easy observation by the operator.

[0069] In use, a drone lifts the cable de-icing device above the cable 1000, then lowers it so that the cable 1000, guided by the guide frame 120, enters between the second roller 220 and the first roller 210. Then, the lifting drive 221 actuates, causing the second roller 220 to rise and clamp the cable 1000 between the second roller 220 and the first roller 210. The de-icing drive 320 actuates, first causing the upper de-icing component 330 to descend to contact the cable 1000. Above the cylindrical ice layer 2000, the de-icing support 310 is driven to rise, causing the lower de-icing component 340 to rise and abut against the lower side of the cylindrical ice layer 2000. This results in the upper de-icing component 330 and the lower de-icing component 340 both extending at least partially into the cylindrical ice layer 2000. Then, the walking drive and cleaning drive 430 are activated, and the frame 100 moves forward. The upper ice blade 332 and lower ice blade 342 cut open the cylindrical ice layer 2000, causing it to break and fall. During the movement, the first roller 210 and the second roller 220 also peel ice off the cable 1000, and the cleaning component 420 vibrates and scrapes to separate the broken ice from the cable 1000, completing the de-icing operation.
