Description

Technical Field

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

[0002] When cold waves or frost disasters occur, overhead lines will be affected by ice, which is a cylindrical layer of ice attached to the lines. Ice may cause line breakage, tower collapse, insulation degradation, and other problems, leading to power failures and large-scale power outages. This will seriously threaten the safe and stable operation of the power system.

[0003] In order to maintain the lines and remove the ice, a lot of manpower and funds are needed for inspection and de-icing. Existing de-icing equipment is mainly divided into two types: hot melt method and mechanical vibration method. Among them, the hot melt method uses high temperature or chemical agents to reduce the melting point of ice, but this method may damage the wires and is not efficient. The mechanical vibration method uses the impact force generated by the power source to vibrate and destroy the ice layer. Commonly used power sources include gunpowder and electric explosive devices. However, there are many limitations on the use of gunpowder, such as long use intervals, strict control, and inconvenience in carrying, which leads to poor convenience of use; at the same time, the electric explosive device is easily affected by impact due to its complex structure, resulting in unsatisfactory de-icing effect.

[0004] Therefore, it is urgent to study a cable deicing device to improve the convenience of use and the efficiency of deicing. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0042] like Figures 1 to 7 As shown, this embodiment provides a cable deicing device, which improves the deicing efficiency on the cable 1000 and the convenience of use. The cable deicing device includes a frame 100, a travel assembly 200 and a travel assembly 200, wherein the travel assembly 200 is arranged on the frame 100, and is used to abut the cable 1000 and can travel along the extension direction of the cable 1000; the deicing assembly 300 includes a deicing bracket 310, a deicing drive 320, an upper deicing member 330 and a lower deicing member 340, the deicing bracket 310 is movably arranged on the frame 100 in the vertical direction, the deicing drive 320 is arranged on the deicing bracket 310, and the output end of the deicing drive 320 can reciprocate in the vertical direction, and the lower deicing member 340 is fixedly arranged. At the lower end of the de-icing bracket 310, the upper de-icing component 330 is located on the upper side of the lower de-icing component 340 and is transmission-connected to the output end of the de-icing driving component 320. During the downward movement of the output end of the de-icing driving component 320, the upper de-icing component 330 can be 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 can be 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, so that the upper de-icing component 330 at least partially extends into the cylindrical ice layer 2000, and the lower de-icing component 340 at least partially extends into the cylindrical ice layer 2000.

[0043] In this state, when the walking component 200 moves along the cable 1000, the upper de-icing component 330 and the lower de-icing component 340 can cut the cylindrical ice layer 2000. Considering the brittleness of ice itself, the cylindrical ice layer 2000 is broken as a whole at the moment of being cut, so that it can fall from the cable 1000, 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, which saves energy. At the same time, the de-icing process does not require gunpowder, and is more convenient to use. Finally, with the help of the movable deicing bracket 310, in the process of the upper deicing component 330 and the lower deicing component 340 approaching each other, the upper deicing component 330 and the lower deicing component 340 are automatically aligned with the cable 1000 as the center. After the cable 1000 is clamped by the upper deicing component 330 and the lower deicing component 340, no matter how big or small the diameter of the cable 1000 is, the cable 1000 will not bend, so that the central axis of the cable 1000 of different diameters passes through the middle position between the upper deicing component 330 and the lower deicing component 340, thereby avoiding scratches on the surface of the cable 1000 during the movement; when facing cables 1000 of different diameters, there is no need for separate debugging, thereby improving the deicing efficiency. It should be noted that when the upper deicing component 330 and the lower deicing component 340 clamp the cable 1000, the distance between the upper deicing component 330 and the lower deicing component 340 is greater than the diameter of the cable 1000.

[0044] Combination Figures 2 to 4 As shown, in some embodiments, the deicing 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 in the vertical direction, the upper end of the first guide member 313 is connected to the upper fixing plate 311, the lower end of the first guide member 313 is connected to the lower fixing plate 312, the rack 100 is provided with a guide hole extending in the vertical direction, the first guide member 313 is penetrated in the guide hole, and can slide in the vertical direction relative to the rack 100. The first guide member 313 serves as a connecting member connecting the upper fixing plate 311 and the lower fixing plate 312, and also serves as a sliding connection component between the deicing bracket 310 and the rack 100. Finally, the first guide member 313 also serves as a sliding carrier of the upper deicing member 330, one object has three uses, and the structure is ingenious, which helps to reduce the production cost of the deicing bracket 310.

[0045] In order to ensure that the cylindrical ice layer 2000 can be cut smoothly, the upper deicing member 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 is provided with a mounting hole extending in the vertical direction. The first guide member 313 is penetrated in the mounting hole. The output end of the deicing driving member 320 is transmission-connected with the upper mounting plate 331. The upper mounting plate 331 can slide relative to the first guide member 313. This arrangement enables the upper ice blade 332 to cut a gap on the upper side of the cylindrical ice layer 2000 during the movement of the rack 100.

[0046] The lower de-icing member 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 enables the lower ice blade 342 to cut a gap on the lower side of the cylindrical ice layer 2000 during the movement of the rack 100. It should be noted that the sharpness of the blades of the upper ice blade 332 and the lower ice blade 342 is not enough to cut the cable 1000.

[0047] In order to effectively disintegrate the cylindrical ice layer 2000, the upper de-icing member 330 includes an upper ice blade 332, and the lower de-icing member 340 includes two lower ice blades 342. When the upper ice blade 332 partially extends into the cylindrical ice layer 2000, and the lower ice blade 342 partially extends into the cylindrical ice layer 2000, the upper ice blade 332 and the lower ice blade 342 are arranged around the outer periphery of the cable 1000. Among them, the two lower ice blades 342 are arranged at intervals in the left and right directions. The three ice blades cut the cylindrical ice layer 2000 at the same time, and the cutting positions are dispersed around the outer periphery of the cable 1000, so that the cylindrical ice layer 2000 can be divided into three smaller ice blocks, and separated from each other into a non-annular structure, thereby effectively reducing the attachment area of ​​the ice blocks and the cable 1000, and it is easier to slide off the cable 1000 under the action of gravity. In some embodiments, the angle between the two lower ice blades 342 is 40° to 70°, and the upper ice blade 332 is located directly above the cylindrical ice layer 2000, and the plane where the upper ice blade 332 is located passes through the axis of the cable 1000. Exemplarily, the angle between the two lower ice blades 342 is 50°, and the angle between the upper ice blade 332 and any one of the lower ice blades 342 is 155°. In some embodiments, the angle α between the upper ice blade 332 and any two of the two lower ice blades 342 is 60°.

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

[0049] During the movement of the rack 100, in order to improve the cutting efficiency of the upper ice blade 332, at least the front end of the upper ice blade 332 is provided with a chamfer. Preferably, the blade of the upper ice blade 332 is arc-shaped and bulges downward. In order to improve the cutting efficiency of the lower ice blade 342, at least the front end of the lower ice blade 342 is provided with a chamfer. In some embodiments, the blade of the lower ice blade 342 is arc-shaped and bulges toward the axial direction of the cable 1000. In other words, the blade of the upper ice 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-to-back direction are located outside the cylindrical ice layer 2000. Similarly, the blade of the lower ice blade 342 is arc-shaped, and the middle part of the blade of the lower ice blade 342 is inserted into the cylindrical ice layer 2000, and the two ends of the blade of the lower ice blade 342 in the front-back direction are located outside the cylindrical ice layer 2000, thereby playing a guiding role. During the operation of the cable deicing device, the cylindrical ice layer 2000 is introduced between the upper ice blade 332 and the lower ice blade 342 for easy cutting. In other embodiments, the upper ice blade 332 and the lower ice blade 342 can both be provided with inclined chamfers at the front end, as long as it is ensured that the cylindrical ice layer 2000 can be smoothly introduced between the upper ice blade 332 and the lower ice blade 342 during the operation of the cable deicing device.

[0050] In some embodiments, the surface of the lower mounting plate 341 on which the lower ice blade 342 is mounted is an inclined surface, sloping downward from front to back, so that the crushed ice that falls onto the lower mounting plate 341 can slide backwards and avoid accumulation on the lower mounting plate 341, thereby ensuring the smoothness of the lower ice blade 342 in cutting the cylindrical ice layer 2000.

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

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

[0053] To ensure the stability of 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 arranged at intervals, and 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 deicing drive member 320 is a rotary drive member, and the deicing assembly 300 includes a first screw rod 350 and a drive nut. The first screw rod 350 is rotatably disposed on the deicing bracket 310 and is transmission-connected to the output end of the rotary drive member. The drive nut and the first screw rod 350 are threadedly matched and connected to the upper deicing member 330. The rotary drive member is a servo motor. The above arrangement can realize the driving function of the upper deicing member 330, and has a self-locking function, so as to avoid the distance between the upper deicing member 330 and the lower deicing member 340 changing during the walking process of the rack 100, thereby ensuring the deicing effect. Of course, in other embodiments, the deicing drive member 320 can be a push rod motor, wherein the push rod motor is arranged on the upper fixed plate 311.

[0055] Combination Figure 1 and Figure 5 As shown, considering that some ice cubes or ice debris remain on the cable 1000, in order to further clean them, the cable deicing device also includes a cleaning component 400, and the cleaning component 400 includes a cleaning shell 410 and a cleaning member 420. The cleaning end of the cleaning member 420 is used to abut the upper side of the cable 1000. Along the cleaning direction X, the cleaning member 420 can reciprocate relative to the cleaning shell 410 so that the cleaning end scrapes the upper side of the cable 1000, and the angle β between the cleaning direction X and the extension direction of the cable 1000 is set at an acute angle. The angle between the cleaning direction X and the opening facing forward in the extension direction of the cable 1000 is an acute angle. This setting allows the cleaning member 420 to press the cable 1000 downward during its movement, thereby ensuring that the cleaning end and the cable 1000 are in good contact, effectively improving the cleaning effect.

[0056] In some embodiments, the cleaning member 420 is in the form of a sheet, the length of the cleaning member 420 is greater than or equal to the diameter of the cable 1000, and the angle between the cleaning member 420 and the cable 1000 is an acute angle. The above structure enables the cleaning member 420 to scoop up the crushed ice when it moves backward, so that it can slide off the cable 1000. The angle between the cleaning member 420 and the cable 1000 opens forward.

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

[0058] In some embodiments, the cleaning member 420 moves between a first position and a second position, wherein the cleaning member 420 at the first position contacts the cable 1000, and the cleaning member 420 at the second position is separated from the cable 1000. This arrangement causes the cleaning member 420 to vibrate at the moment of contacting the cable 1000, thereby shaking off the ice, and further enables the cleaning member 420 to have both vibration and scooping cleaning effects.

[0059] Regarding the driving structure, in some embodiments, the cleaning assembly 400 further includes a cleaning driving member 430, a cam 440, a crankshaft 450, and a slider 460. The cleaning housing 410 is connected to the frame 100. The cleaning driving member 430 is disposed in the cleaning housing 410. The cam 440 is disposed at the output end of the cleaning driving member 430. The slider 460 slides along the cleaning direction X and is disposed on the second guide member 470 of the cleaning housing 410. The two ends of the crankshaft 450 are respectively hinged to the cam 440 and the slider 460. The cleaning member 420 is fixed to the slider 460. The above structure makes it easy to realize the reciprocating motion of the cleaning member 420, and the running speed is 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 at intervals in the vertical direction and are used to clamp on both sides of the cable 1000, and at least one of the first roller 210 and the second roller 220 can actively rotate, and the second roller 220 can move closer to or away from the first roller 210. Exemplarily, the first roller 210 can actively rotate, wherein the walking assembly 200 also includes a walking drive member, which is arranged on the frame 100, and the first roller 210 is drivingly connected to the output end of the walking drive member.

[0061] Among them, the first roller 210 is located above the second roller 220, and the walking assembly 200 also includes a lifting drive member 221, a second screw rod 224 and a lifting block 222. The lifting drive member 221 is arranged on the frame 100, and the second screw rod 224 is rotatably arranged on the frame 100 and is transmission-connected to the lifting drive member 221. The lifting block 222 is provided with a screw hole and a third guide member 223 is slidably arranged on the frame 100 along the vertical direction. The second roller 220 is rotatably arranged on the lifting block 222, and the second screw rod 224 is threadedly matched with the screw hole of the lifting block 222.

[0062] There are two first rollers 210, which are arranged at intervals along the extension direction of the cable 1000. The 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 height direction is smaller than the diameter of the cable 1000. This arrangement allows the cable 1000 to bend after being clamped by the second roller 220 and the first roller 210, thereby ensuring that the first roller 210 and the second roller 220 clamp the cable 1000 and ensure friction; in addition, the bent cable 1000 breaks the cylindrical ice layer 2000 above, thereby achieving a de-icing effect.

[0063] In some embodiments, both first rollers 210 can actively rotate, which improves the driving power, helps to avoid slipping, and improves walking reliability.

[0064] Combined with the deicing assembly 300, the walking assembly 200 and the cleaning assembly 400, the cable deicing device realizes three-level deicing work at the front, middle and rear, so that the deicing effect of the cable 1000 is effectively guaranteed.

[0065] To ensure that the cable 1000 and the first roller 210 are not misaligned, in some embodiments, the first roller 210 is provided with an annular groove in its circumference, and the cable 1000 can be located in the annular groove. The second roller 220 is also provided with 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 placing the cable deicing device on the cable 1000, a drone can be used for operation. A hoisting member 110 is set on the top of the frame 100, and a hook is set under the drone to hook the hoisting member 110. The cable deicing device is lifted to the cable 1000, and the cable 1000 is placed between the first roller 210 and the second roller 220.

[0067] Combination Figure 7 As shown, in order to facilitate placing the cable 1000 between the first roller 210 and the second roller 220, in some embodiments, a guide frame 120 is provided on the rack 100, and the guide frame 120 is inclined from top to bottom away from the rack 100, and the connection between the guide frame 120 and the rack 100 is located below the first roller 210 and above the second roller 220. The folding structure between the guide frame 120 and the rack 100 facilitates the process of placing the cable deicing device downward, so that the cable 1000 enters 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 for transmitting the captured image to the operation interface for easy observation by the operator.

[0069] When in use, the cable deicing device is lifted to the top of the cable 1000 by the drone, and then the cable deicing device is lowered, so that the cable 1000 enters between the second roller 220 and the first roller 210 under the guidance of the guide frame 120, and then the lifting drive member 221 is actuated to make the second roller 220 rise and clamp the cable 1000 between the second roller 220 and the first roller 210; the deicing drive member 320 is actuated to first make the upper deicing member 330 descend to abut against the outer surface of the cable 1000 The upper side of the cylindrical ice layer 2000 is driven to move the de-icing bracket 310 upward to drive the lower de-icing member 340 to move upward and abut against the lower side of the cylindrical ice layer 2000, and finally the upper de-icing member 330 at least partially extends into the cylindrical ice layer 2000, and the lower de-icing member 340 at least partially extends into the cylindrical ice layer 2000; then the travel drive member and the cleaning drive member 430 are started, the frame 100 moves forward, the upper ice blade 332 and the lower ice blade 342 cut the cylindrical ice layer 2000, and the cylindrical ice layer 2000 breaks and falls. During the moving process, the first roller 210 and the second roller 220 also peel off the ice from the cable 1000 during the movement process, and the cleaning member 420 can generate vibration and shovel action to separate the crushed ice from the cable 1000, completing the de-icing work.
