Description

Technical Field

[0001] This invention relates to the field of power equipment maintenance technology, specifically to a pole de-icing device. Background Technology

[0002] Most existing de-icing devices remove ice from the surface of utility poles by using knives or hammering. For example, Chinese patent application number 2017110466586 discloses "A De-icing Device for Utility Poles", and Chinese patent application number 2024100481541 discloses "A De-icing Device for Utility Poles Applicable to High-Altitude and Cold Regions". These devices are suitable for removing most of the ice on the utility poles, but a small amount will still remain. They are suitable for weight reduction de-icing to prevent the thick ice from collapsing the poles, but not for de-icing before maintenance.

[0003] Especially for cement utility poles, the surface has pits and depressions of varying sizes. When using methods such as shoveling or knocking to remove ice, only most of the ice that has solidified on the surface can be removed. The thin layer of ice remaining in the pits and depressions still adheres to the surface of the utility pole, resulting in a smooth surface after de-icing. This makes it easy for workers to slip when climbing the pole using foot straps, posing a safety hazard. In addition, the utility poles are shaped like a gradually tapering frustum, which is smaller at the top and larger at the bottom. It is difficult for the de-icing components to stay in close contact with the surface of the utility pole and adapt to the changes in the diameter of the pole as they move along the pole. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a pole de-icing device, comprising two de-icing mechanisms symmetrically arranged around the pole. Each de-icing mechanism includes a housing, a fixed plate fixed inside the housing, and a slider slidably connected to the housing. A motor is fixedly mounted on the slider, and an active roller is rotatably connected to the slider. The motor is driven by the active roller to drive the active roller to rotate. Two sets of connecting rods are rotatably connected to the fixed plate. Each set of connecting rods is rotatably connected to a follower roller at the end away from the fixed plate. De-icing belts are wound around the driving roller and the two follower rollers. A first elastic element for driving the slider to move away from the utility pole is fixedly installed between the fixed plate and the slider. The active roller moves away from the utility pole to tighten the de-icing belt to fit the utility pole and bring the two follower rollers closer to each other to clamp the utility pole.

[0005] As a preferred technical solution of the present invention, it further includes a support mechanism, which includes a left base and a right base that are rotatably connected to each other. Two de-icing mechanisms are respectively fixedly installed on the left base and the right base, and a latch is fixedly installed on the side of the left base and the right base away from the rotating axis.

[0006] As a preferred embodiment of the present invention: a moving mechanism is slidably connected to the left base and the right base respectively. The moving mechanism includes a slide rod slidably connected to the left base or the right base. A pulley is fixedly installed at one end of the slide rod near the utility pole. A third elastic element for driving the pulley to abut against the utility pole is fixedly installed on the left base or the right base.

[0007] As a preferred embodiment of the present invention: anti-slip components are respectively provided on the left base and the right base, the anti-slip components include a locking member rotatably connected to the left base or the right base, and a fourth elastic member for driving the locking member to abut against the utility pole is fixedly installed on the left base or the right base.

[0008] As a preferred technical solution of the present invention: the bearing mechanism is provided with an anti-detachment mechanism, the anti-detachment mechanism includes a pin and an extension plate fixedly installed on the left base, the right base has a groove matching the extension plate, the right base has a vertical hole communicating with the groove, the extension plate has an insertion hole matching the vertical hole, and the pin is inserted into the vertical hole and the insertion hole to fix the relative position of the left base and the right base.

[0009] As a preferred embodiment of the present invention: an ice-breaking mechanism is fixedly installed on the two housings. The ice-breaking mechanism includes a plurality of elastic rods fixedly installed on the two housings. All the elastic rods are arranged in a circular pattern to wrap around the utility pole. An ice-breaking blade is fixedly installed on the top of the elastic rods near the utility pole.

[0010] As a preferred technical solution of the present invention: a rectangular sleeve is fixedly installed on the side of the top of the elastic rod away from the utility pole, and the ice-breaking mechanism further includes a clamp passing through all the rectangular sleeves. The clamp includes two rotatably connected semicircular components, and the axis of rotation between the two semicircular components is coaxial with the axis of rotation between the left base and the right base.

[0011] As a preferred embodiment of the present invention: the blade tip of the icebreaker is inclined toward the axis of the utility pole, and the width of the icebreaker gradually increases from top to bottom.

[0012] As a preferred embodiment of the present invention: the drive shaft of the motor is fixedly connected to a sub-gear, and the drive roller is fixedly mounted with a coaxial female gear, the sub-gear and the female gear meshing.

[0013] As a preferred embodiment of the present invention, a second elastic element is fixedly installed between the two sets of connecting rods.

[0014] The present invention has the following beneficial effects: This invention uses a motor to drive an active drum to rotate, which in turn drives a de-icing belt wrapped around the active drum and two follower drums to rotate. This causes the de-icing belt to come into contact with and rub against the surface of the utility pole to remove the ice layer. This effectively removes the ice layer from the surface of the utility pole, avoiding the incomplete de-icing and thin ice residue that can occur with traditional ice-shoveling methods due to the uneven surface of the utility pole. This prevents the surface of the utility pole from remaining smooth and avoids slipping when workers use foot straps to climb the pole, thus ensuring operational safety.

[0015] The first elastic element drives the slider to move the active roller away from the utility pole, tightening the de-icing belt to fit the utility pole and bringing the two follower rollers closer together to clamp the utility pole. This maintains the holding pressure of the two follower rollers on the utility pole, ensuring that the de-icing belt always fits the surface of the utility pole and adapts to changes in the diameter of the utility pole, which helps to ensure the de-icing effect.

[0027] The principles and features of the present invention are described below. The embodiments given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0028] It should be noted that when a part or component is considered to be "connected to," "located on," or "assembled" to another part or component, it can be directly mounted on the other part or component, or it may be located in an intermediate part or component. The terms "left," "right," "upper," "lower," and similar expressions used in this document are for illustrative purposes only.

[0029] After careful research and analysis, the applicant discovered that most existing de-icing devices use shovels to remove ice from utility poles 1. However, a significant portion of the existing utility poles 1 are constructed of concrete, resulting in numerous pits and grooves of varying sizes on their surfaces. When removing ice by shoveling, the uneven surface causes the ice layer to become discontinuous or easily break apart. This results in the ice fragmenting during shoveling, removing only the majority of the ice solidified on the surface. Small pieces of thin ice remain adhered to the unremoved areas, leaving the pole surface slippery. This makes it easy for workers to slip when using footholds to climb the poles, creating a safety hazard. Figure 1As shown. To address this safety hazard in a practical way, the de-icing method needs to be changed from a scraping method to a friction de-icing method that involves a large area of ​​contact with the surface of the utility pole 1. Since the diameter of the utility pole 1 is a gradually changing frustum shape with a smaller diameter at the top and a larger diameter at the bottom, the design of the de-icing belt 308 for friction de-icing also needs to consider the fit design of the de-icing belt 308 with the utility pole 1 during movement, in order to adapt to the change in the diameter of the utility pole 1.

[0030] like Figure 2-5 As shown, based on the above concept, this application designs a pole de-icing device, specifically including two de-icing mechanisms 3 symmetrically arranged around a utility pole 1. Each de-icing mechanism 3 includes a housing 301, a fixing plate 302 fixed within the housing 301, and a slider 306 slidably connected to the housing 301. Semi-circular grooves are respectively formed on opposite sides of the two housings 301, and the diameter of the circle formed by the two semi-circular grooves is larger than the maximum diameter of the utility pole 1. The utility pole 1 is located within the two semi-circular grooves. The slider 306 is located on the side of the fixing plate 302 away from the utility pole 1. A groove 305 extending radially along the utility pole 1 is formed on the inner bottom wall of the housing 301. The bottom of the slider 306 extends into and fits into the groove 305 to achieve a sliding connection with the housing 301. The length direction of the groove 305 guides the slider 306. A motor 310 is fixedly mounted on the slider 306, and a drive roller 307 is rotatably connected to the slider 306. The motor 310 is driven by the drive roller 307 to rotate. That is, when the slider 306 moves, it drives the motor 310 and the drive roller 307 to move synchronously, so that the motor 310 can also drive the drive roller 307 to rotate when the drive roller 307 is moving.

[0031] Two sets of connecting rods 303 are rotatably connected to the fixed plate 302. Each set of connecting rods 303, at its end furthest from the fixed plate 302, is rotatably connected to a follower roller 304. Each set of connecting rods 303 consists of upper and lower sections, respectively rotatably connected to the upper and lower sides of the central shaft of the follower roller 304. This allows the follower roller 304 to rotate on its own axis and also revolve around the axis at the connection point between the connecting rods 303 and the fixed plate 302. It is worth noting that the axes of rotation of the connecting rods 303, the fixed plate 302, the follower roller 304, and the driving roller 307 are all parallel to each other and are vertical during operation. The de-icing belt 308 is wound around the driving roller 307 and the two follower rollers 304. The de-icing belt 308 is connected end-to-end in a closed loop, and its outer surface is rough. For example, the outer surface of the de-icing belt 308 can be provided with a layer of steel wire or bristles to improve the de-icing effect. To prevent slippage between the de-icing belt 308 and the driving roller 307 and the two follower rollers 304, matching toothed grooves can be provided on the inner side of the de-icing belt 308 and the outer side walls of the driving roller 307 and the two follower rollers 304, so that the de-icing belt 308 meshes with the driving roller 307 and the two follower rollers 304, thus preventing the friction from being too small to drive the de-icing belt 308 to rotate.

[0032] A first elastic element 309 is fixedly installed between the fixed plate 302 and the slider 306 to drive the slider 306 to move away from the utility pole 1. There can be multiple first elastic elements 309. The slider 306 is L-shaped. When the slider 306 moves, it drives the active roller 307 to move. The active roller 307 moves away from the utility pole 1 to tighten the de-icing belt 308 to fit against the utility pole 1 and to bring the two follower rollers 304 closer together to clamp the utility pole 1.

[0033] The follower roller 304 is suspended inside the housing 301, and the two follower rollers 304 are respectively located on both sides of the semi-circular groove, so that the follower roller 304 can rotate into the semi-circular groove to support the utility pole 1, and the portion of the de-icing belt 308 between the two follower rollers 304 can cover the surface of the utility pole 1.

[0034] Regarding the power source for driving the motor 310, a power supply can be installed inside the housing 301, or an external power supply can be connected via wires. Both implementation methods are existing mature technologies and will not be elaborated further here. It is worth noting that when using an external power supply via wires, the distance of the wires should be long enough to ensure that the movable stroke of the de-icing mechanism 3 is sufficient.

[0035] The operating principle is as follows: two de-icing mechanisms 3 are positioned opposite each other to wrap the utility pole 1 within the circular opening formed by the two semi-circular grooves, and the relative positions of the two de-icing mechanisms 3 are fixed to maintain the wrapping state. During the wrapping process, the portion of the de-icing belt 308 between the two follower rollers 304 adaptively forms an arc shape to wrap and adhere to the side of the utility pole 1. At the same time, the two follower rollers 304 are pushed open by the utility pole 1 and rotate to opposite sides. This causes the de-icing belt 308 to pull the drive roller 307 to move closer to the side of the utility pole 1, compressing the first elastic element 309 and pre-storing a certain amount of rebound force in the first elastic element 309. The motor 310 is started to drive the drive roller 307 to rotate, causing the drive roller 307 to drive the de-icing belt 308 to rotate and generate friction with the side of the utility pole 1, grinding away the ice on the side of the utility pole 1. Simultaneously, the de-icing mechanism 3 moves upward, completing the removal of the ice layer on the side of the utility pole 1. As the pole moves upward, the diameter of the utility pole 1 gradually decreases. When the diameter decreases, the rebound force of the first elastic element 309 drives the active roller 307 to move away from the utility pole 1. The de-icing belt 308 pulls the two follower rollers 304 to rotate towards each other, so that the two follower rollers 304 always maintain a certain pressure against the utility pole 1. At the same time, the de-icing belt 308 is tightened to prevent slippage between the de-icing belt 308 and the active roller 307.

[0036] Since only the de-icing belt 308 between the two moving rollers 304 contacts the utility pole 1, during de-icing, only the ice in the arc-shaped area between the two moving rollers 304 is cleared on the same horizontal plane, forming two opposing de-icing areas. Ice outside this area remains. If the de-icing mechanism 3 is not rotated during de-icing, and only a vertical movement is used, two vertical and opposing un-iced areas will exist on the side of the utility pole 1. When climbing the pole, workers should avoid placing the part of the foot straps that contacts the utility pole 1 within the un-iced area. That is, the un-iced area should be located on either side of the worker's body, while the front and rear sides of the foot straps that create friction with the utility pole 1 should be within the de-icing area. Since the contact points between the foot straps and the utility pole 1 are also relatively opposite—one on the side of the utility pole 1 closer to the worker's body and the other on the side farther away—safe pole climbing can also be achieved.

[0037] In use, the de-icing mechanism 3 can also be rotated while moving it upwards to remove the aforementioned un-iced areas. Alternatively, after moving the de-icing mechanism 3 to the desired top, it can be lowered, rotated 90 degrees, and then moved upwards again to remove all the ice from the side of the utility pole 1.

[0038] Regarding the method of driving the de-icing mechanism 3, it can be that the worker climbs the pole to drive the de-icing mechanism 3 to move, that is, the de-icing mechanism 3 is on top and the foot straps are on the bottom. The worker climbs up a certain distance, moving the de-icing mechanism 3 upwards a certain distance. Alternatively, it can be pushed upwards by a long pole, telescopic pole, or other means, or a pole-climbing robot can be used to drive the de-icing mechanism 3 upwards. The implementation method can be selected according to cost and other factors, and will not be elaborated further here.

[0039] To replace the de-icing belt 308, simply bring the two follower rollers 304 closer together and move the drive roller 307 toward the utility pole 1, so that the de-icing belt 308 is released from tension and detached from the follower rollers 304 and the drive roller 307, and it can be removed.

[0040] Example 1 like Figure 3 , Figure 7 and Figure 10 As shown, the pole de-icing device of this embodiment has a basic structure that is basically the same as the pole de-icing device of this application, the difference being the specific structure of the bearing mechanism 2.

[0041] The system also includes the supporting mechanism 2, which comprises a left base 201 and a right base 202 rotatably connected to each other. Semicircular grooves are respectively formed on opposite sides of the left base 201 and the right base 202, and these semicircular grooves match each other. Two de-icing mechanisms 3 are respectively fixedly installed on the left base 201 and the right base 202, causing the semicircular grooves to overlap. Locking buckles 8 are fixedly installed on the side of the left base 201 and the right base 202 away from the pivot.

[0042] In this embodiment, the rotatable connection between the left base 201 and the right base 202 is achieved by a hinge, and the rotatable connection between the two de-icing mechanisms 3 is also achieved by the rotatable connection between the left base 201 and the right base 202.

[0043] The latch 8 includes a corresponding sub-latch 801 and a female latch 802, which are respectively fixedly installed on the left base 201 and the right base 202. When the left base 201 and the right base 202 rotate to approach each other, the female latch 802 can fasten the sub-latch 801, and by leveraging the rotation of the female latch 802, the sub-latch 801 is pulled until the left base 201 and the right base 202 are in contact. At this time, the female latch 802 rotates to its maximum stroke. By setting the latch 8, when the utility pole 1 squeezes the de-icing belt 308, causing the first elastic element 309 to be compressed and increasing resistance, the left base 201 and the right base 202 can be rotated to contact in a more effortless manner.

[0044] In this embodiment, the supporting mechanism 2 also includes two handles 203, which are symmetrically fixed on the left and right sides of the left base 201, making it convenient for workers to hold and operate when moving the de-icing mechanism 3.

[0045] Example 2 like Figure 7 As shown, the pole de-icing device in this embodiment is a further improvement on the basis of Embodiment 1, the difference being the specific structure of the moving mechanism 6.

[0046] A moving mechanism 6 is slidably connected to the left base 201 and the right base 202, respectively. The moving mechanism 6 includes a slide rod 602 slidably connected to either the left base 201 or the right base 202. Specifically, the left base 201 and the right base 202 each have a cylindrical hole radially parallel to the utility pole 1. The two slide rods 602 are inserted into the two cylindrical holes to achieve a slidable connection with either the left base 201 or the right base 202. An installation groove 604 is provided on opposite sides of the left base 201 and the right base 202. The cylindrical hole communicates with the installation groove 604. A pulley 601 is fixedly installed at the end of the slide rod 602 closest to the utility pole 1, and the pulley 601 is located within the installation groove 604. A third elastic element 603 for driving the pulley 601 to abut against the utility pole 1 is fixedly installed on the left base 201 or the right base 202. Specifically, the third elastic element 603 is sleeved on the slide rod 602, and one end of the third elastic element 603 abuts against the side wall of the mounting groove 604. After the left base 201 and the right base 202 rotate to wrap around the utility pole 1, the utility pole 1 squeezes the pulley 601, causing the third elastic element 603 to be compressed, so that during de-icing, the pulley 601 contacts the utility pole 1 and maintains a certain pressure. The two pulleys 601 can also assist in centering, that is, help to make the friction between the two de-icing belts 308 and the utility pole 1 approximately equal.

[0047] In this embodiment, the pulley 601 is a one-way wheel, meaning that the pulley 601 has a ratchet structure inside, allowing it to roll only in one direction. Specifically, when the de-icing mechanism 3 moves upward, the pulley 601 can roll; when the de-icing mechanism 3 moves downward, the pulley 601's rolling is restricted, increasing the friction between the pulley 601 and the utility pole 1 and preventing the de-icing mechanism 3 from falling due to its own weight.

[0048] Example 3 like Figure 7 , Figure 8 and Figure 9 As shown, the pole de-icing device in this embodiment is a further improvement on the basis of embodiment two. The difference lies in the specific structure of the anti-slip component 7, and in this embodiment, the pulley 601 can be a non-unidirectional wheel.

[0049] Anti-slip components 7 are respectively provided on the left base 201 and the right base 202. Side grooves 701 are respectively formed on opposite sides of the left base 201 and the right base 202, and the two side grooves 701 are symmetrically distributed. Each anti-slip component 7 includes a locking member 702 rotatably connected to the left base 201 or the right base 202, and the two locking members 702 are respectively located within the two side grooves 701. A fourth elastic member 703 for driving the locking member 702 to abut against the utility pole 1 is fixedly installed on the left base 201 or the right base 202, such as... Figure 8 As shown, the fourth elastic member 703 is stretched so that the bottom of the clip 702 rotates to contact the utility pole 1.

[0050] like Figure 9 As shown, in this embodiment, the bottom of the anti-slip component 7 is shaped like a raised strip 704, and the side edge of the raised strip 704 contacts the utility pole 1.

[0051] The locking element 702 is similar to a pry bar. During de-icing, as the de-icing mechanism 3 moves upward, the friction between the locking element 702 and the utility pole 1 remains constant within a small range, allowing the de-icing mechanism 3 to move smoothly upward. When the de-icing mechanism 3 loses external support and falls downward, the gravity of the utility pole de-icing device of this application causes the locking element 702 to rotate. With the contact point between the bottom of the locking element 702 and the utility pole 1 as the axis, the downward pressure causes the locking element 702 to tend to rotate horizontally, and the bottom of the locking element 702 to tend to rotate closer to the axis of the utility pole 1. This continuously increases the friction between the locking element 702 and the utility pole 1 during the fall, thus locking the utility pole de-icing device of this application and preventing further descent. In actual use, even if the operator cannot provide support to the de-icing mechanism 3 throughout the entire process, the utility pole de-icing device of this application will not fall.

[0052] Example 4 like Figure 5 and Figure 6 As shown, the pole de-icing device in this embodiment is a further improvement on the basis of Embodiment 1, the difference being the specific structure of the anti-detachment mechanism 5.

[0053] The supporting mechanism 2 is provided with an anti-detachment mechanism 5, which includes a pin 504 and an extension plate 505 fixedly installed on the left base 201. The right base 202 has a groove 501 that matches the extension plate 505. Both the groove 501 and the extension plate 505 are located on the side away from the pivot of the left base 201 and the right base 202. The right base 202 has a vertical hole 502 that communicates with the groove 501. The extension plate 505 has a socket that matches the vertical hole 502. The diameters of the socket and the vertical hole 502 are equal and both match the pin 504. The pin 504 is inserted into the vertical hole 502 and the socket to fix the relative position of the left base 201 and the right base 202 and prevent the left base 201 and the right base 202 from shaking. When the left base 201 and the right base 202 are rotated to fit together, the insertion hole and the vertical hole 502 overlap, so that the pin 504 can be inserted into the insertion hole and the vertical hole 502 at the same time, thereby locking the left base 201 and the right base 202.

[0054] A pull ring is fixedly installed on the top of the pin 504.

[0055] Combination Figure 3 In this embodiment, the side wall of the housing 301 located above the right base 202 is provided with a clearance groove 503 located above the vertical hole 502. The height of the clearance groove 503 is greater than the height of the pin 504, so that the insertion and removal of the pin 504 are not affected.

[0056] By setting the anti-detachment mechanism 5, a locking process is added for the left base 201 and the right base 202. After the left base 201 and the right base 202 are pulled closer by the latch 8, the anti-detachment mechanism 5 performs precise positioning and locking.

[0057] Example 5 like Figure 3 and Figure 4 As shown, the pole de-icing device of this embodiment has a basic structure that is basically the same as the pole de-icing device of this application, the difference being the specific structure of the ice-breaking mechanism 4.

[0058] An ice-breaking mechanism 4 is fixedly installed on both housings 301. The ice-breaking mechanism 4 includes multiple elastic rods 401 fixedly installed on the two housings 301. All the elastic rods 401 are arranged in a circular pattern to wrap around the utility pole 1. An ice-breaking blade 404 is fixedly installed on the top of each elastic rod 401 near the side of the utility pole 1. The multiple elastic rods 401 are evenly distributed along the circumference of the semi-circular groove. The elastic rods 401 are metal springs, and the tops of the elastic rods 401 are inclined towards the axis of the utility pole 1. That is, the diameter of the circle formed by the tops of the multiple elastic rods 401 is smaller than the diameter of the utility pole 1. After the left base 201 and the right base 202 wrap around the utility pole 1, the utility pole 1 abuts against the ice-breaking blade 404, and the elastic rods 401 deform to store elastic force.

[0059] When the ice layer on the side of the utility pole 1 is thick, by setting the ice-breaking mechanism 4, the ice-breaking blade 404 is first embedded in the ice layer before the ice is removed by friction by the de-icing belt 308, which breaks the continuity of the ice layer, causes the ice layer to break and fall off in large pieces, making the ice layer thinner. The remaining ice slag is then removed by friction by the de-icing belt 308, thereby improving the de-icing efficiency.

[0060] Example 6 The pole de-icing device in this embodiment is a further improvement on the fifth embodiment, the difference being the specific structure of the ice-breaking mechanism 4.

[0061] A rectangular sleeve 402 is fixedly installed on the side of the elastic rod 401 away from the utility pole 1. The ice-breaking mechanism 4 also includes a clamp 403 passing through all the rectangular sleeves 402. In this embodiment, the clamp 403 is a hinged clamp, which includes two rotatably connected semicircular components. The axis of rotation between the two semicircular components is coaxial with the axis of rotation between the left base 201 and the right base 202. That is, when the left base 201 and the right base 202 are separated or attached, the two semicircular components can also adapt and rotate accordingly. After the left base 201 and the right base 202 are attached, that is, after the two de-icing mechanisms 3 wrap around the utility pole 1, the clamp 403 is tightened by the other side, which assists the elastic rod 401 in pressing the ice-breaking blade 404 into the ice layer. In other embodiments, the clamp 403 can also be a quick-release clamp, a bolt clamp, etc.

[0062] Example 7 The pole de-icing device in this embodiment is a further improvement on the fifth embodiment, the difference being the specific structure of the ice-breaking mechanism 4.

[0063] The blade 405 at the top of the icebreaker 404 is inclined toward the axis of the utility pole 1, and the width of the icebreaker 404 gradually increases from top to bottom.

[0064] As the de-icing mechanism 3 moves upward, the ice-breaking blade 404 gradually embeds itself deeper into the ice layer, resulting in better ice-breaking performance. By gradually increasing the width of the ice-breaking blade 404, it segments the ice layer after insertion, causing it to break into ice blocks that fall off.

[0065] Example 8 like Figure 6 As shown, the pole de-icing device of this embodiment has a basic structure that is basically the same as the pole de-icing device of this application, the difference being the specific structure of the de-icing mechanism 3.

[0066] The drive shaft of the motor 310 is fixedly connected to a sub-gear 311, and a coaxial master gear 312 is fixedly mounted on the drive roller 307. The sub-gear 311 and the master gear 312 mesh. This enables the motor 310 to drive the drive roller 307 to rotate, and is unaffected by the movement of the slider 306.

[0067] Example 9 The pole de-icing device in this embodiment has a basic structure that is basically the same as the pole de-icing device of this application, except that the de-icing mechanism 3 has a specific structure.

[0068] A second elastic element 314 is fixedly installed between the two sets of connecting rods 303. Specifically, a connecting block 313 is fixedly installed on each set of connecting rods 303, and the two ends of the second elastic element 314 are fixedly connected to the two connecting blocks 313 respectively. The second elastic element 314 assists the two follower rollers 304 in clamping the utility pole 1, thereby improving the de-icing effect.

[0069] In this application, all devices and components whose structures are not described are commercially available devices or components.

[0070] In summary, this invention drives the active roller 307 to rotate via the motor 310, which in turn rotates the de-icing belt 308 wound around the active roller 307 and the two follower rollers 304. This causes the de-icing belt 308 to contact and rub against the surface of the utility pole 1, effectively removing the ice layer. This avoids the incomplete de-icing and residual thin ice that can occur with traditional shoveling methods due to the uneven surface of the utility pole 1, ensuring the surface remains smooth and preventing slippage for workers using footholds to climb the pole, thus guaranteeing operational safety. The first elastic element 309 drives the slider 306 to move the active roller 307 away from the utility pole 1, tightening the de-icing belt 308 to adhere to the utility pole 1 and bringing the two follower rollers 304 closer together to clamp the utility pole 1. This maintains the holding pressure of the two follower rollers 304 on the utility pole 1, ensuring the de-icing belt 308 remains in contact with the surface of the utility pole 1 and adapts to changes in the diameter of the utility pole 1, thus guaranteeing effective de-icing.
