Description

Technical Field

[0001] The present invention relates to the technical field of cable installation, and particularly to an ice removal device for transmission lines in cold regions. Background Art

[0002] In cold regions, the icing problem of transmission lines caused by adverse weather such as low temperature, freezing rain, ice and snow has become an important threat to the safe operation of the power system. Icing will increase the mechanical load of the wire, causing accidents such as line galloping, wire breakage, and tower collapse, and in severe cases, it can lead to regional power outages. Therefore, the development of ice removal technology has gone through multiple stages, but existing methods still have significant limitations in terms of efficiency, energy consumption, adaptability, etc.

[0003] Traditional ice removal technologies include directly removing ice through manual or mechanical devices (such as pulleys, scrapers), melting ice using Joule heat (short-circuit current heating) or external heat sources (such as lasers, electromagnetic induction), or spraying antifreeze agents (such as ethylene glycol, sodium chloride) to lower the freezing point or inhibit ice formation. However, thermal ice melting consumes a large amount of electric energy, which conflicts with the goal of a low-carbon power grid, and extremely low temperatures (such as below -40°C) can cause mechanical ice removal devices to fail. Most technologies rely on manual judgment and lack real-time monitoring and automatic response capabilities.

[0004] For example, the invention patent with the publication number CN115102125B provides a traveling ice removal robot for transmission lines with a locking arm assembly. By setting the locking arm assembly, the angle of the first connecting arm relative to the spreading arm assembly and the angle of the second connecting arm relative to the spreading arm assembly can be locked to stabilize the center of gravity of the device. However, this ice removal device is prone to jamming when the ice layer is thick and hard. Summary of the Invention

[0005] The present invention provides an ice removal device for transmission lines in cold regions to solve the problems that the existing ice removal device is prone to jamming when the ice layer is thick and hard, and the efficiency of the ice removal device is low at positions where the ice layer is thin and soft and easy to break.

[0006] The technical solution of the present invention is: an ice removal device for transmission lines in cold regions includes a housing, a traveling mechanism, a scraping mechanism, and an auxiliary mechanism. The scraping mechanism includes two scraping semi-rings with concave surfaces facing each other arranged on the housing, and the concave surfaces of the scraping semi-rings are in contact with the cable. The traveling mechanism drives the housing to move on the cable.

[0007] The auxiliary mechanism includes a driving component and two clamping components. The two clamping components are circumferentially distributed along the cable. Each clamping component includes a clamping block, a first hinge rod, a second hinge rod, and a first hydraulic cylinder, which are located on the same reference plane parallel to the cable. One end of the first hinge rod is hinged to the housing. One end of the second hinge rod is hinged to the other end of the first hinge rod, and the clamping block is hinged to the other end of the second hinge rod. One end of the first hydraulic cylinder is hinged to the housing, and the other end of the first hydraulic cylinder is hinged to the second hinge rod.

[0008] The auxiliary mechanism has a first working mode and a second working mode. In the first working mode of the auxiliary mechanism, the first hydraulic cylinder is at its longest, the first hinge rod rotates forward, driving the clamping block to move forward and approach the cable for clamping. Forward is the front side in the moving direction of the housing. In the second working mode of the auxiliary mechanism, the first hinge rod rotates reversely, and the first hydraulic cylinder shortens, causing the clamping block to be stationary, and then driving the housing to move forward. The driving component controls the forward and reverse rotation of the first hinge rod to control the alternating conversion between the first working mode and the second working mode.

[0009] Further, two connecting frames are provided on the housing. The two connecting frames are respectively located on both sides in the circumferential direction of the cable. The direction in which the two connecting frames are sequentially distributed is the first direction, and the first direction is the horizontal direction. The connecting frames can slide along the first direction. A first arc groove is provided on each connecting frame. The concave surface of the first arc groove faces the cable.

The first end of the ice-breaking cone is fixedly provided on one side of the scraping semi-ring, and the second end of the ice-breaking cone is used to contact the ice layer on the cable. The plurality of ice-breaking cones are sequentially distributed along the circumferential direction of the scraping semi-ring. The ice-breaking cone is inclined, and there is an angle between the ice-breaking cone and the plane on one side in the axial direction of the cable where the scraping semi-ring is located. And along the rotating direction of the scraping semi-ring, the first end of the ice-breaking cone is at the rear side of the second end.

[0011] Further, a clamping groove is provided at one end of each scraping semi-ring, and a clamping block is provided at the other end of each scraping semi-ring. Each clamping block is arranged in the clamping groove on another scraping semi-ring.

[0012] Further, the housing includes a power storage box, a first support frame, and a second support frame. The first support frame and the second support frame are slidably arranged on the power storage box along the axial direction of the cable. And the first support frame and the second support frame are sequentially distributed along the axial direction of the cable. The first support frame is at the front side in the moving direction of the housing relative to the second support frame. The scraping mechanism and the auxiliary mechanism are both arranged on the first support frame.

[0013] Further, the scraping mechanism further includes a transmission assembly, and the transmission assembly includes a second motor and a bidirectional screw. The second motor is arranged on the first support frame, and the bidirectional screw is fixedly connected to the output shaft of the second motor. The bidirectional screw is arranged along the first direction. Both connecting frames are in screw transmission cooperation with the bidirectional screw, and the screw thread cooperation directions of the two connecting frames and the bidirectional screw are opposite.

[0014] Further, a turbine is fixedly arranged at one end of each first hinge rod connected to the housing. The auxiliary mechanism further includes a driving assembly, and the driving assembly includes a third motor and a worm. The third motor is fixedly arranged on the first support frame, and the worm is fixedly connected to the output shaft of the third motor. The worm meshes with the two turbines.

[0015] Further, each clamping block includes a connecting rod and a clamping head. The connecting rod is arranged vertically, and the upper end of the connecting rod is rotatably connected to the second hinge rod. The clamping head is fixedly arranged at the lower end of the connecting rod. A second arc groove is formed in each clamping head, and the concave surface of the second arc groove faces the cable. A plurality of convex blocks are fixed in the second arc groove, and the convex blocks are in contact with the cable.

[0016] Further, two auxiliary frames are rotatably arranged on both the first support frame and the second support frame. The two auxiliary frames are sequentially distributed along the axial direction of the cable. A torsion spring is arranged at the rotational connection of each auxiliary frame and the first support frame or the second support frame.

[0017] The traveling mechanism includes two traveling assemblies, and the two traveling assemblies are respectively arranged on the first support frame and the second support frame. Each traveling assembly includes a fourth motor, a driving wheel, and two auxiliary clamping wheels. The axial directions of the driving wheel and the auxiliary clamping wheels are both along the first direction. The two driving wheels are respectively rotatably arranged on the first support frame and the second support frame. Each auxiliary clamping wheel is rotatably arranged on an auxiliary frame, and the auxiliary clamping wheel is located below the driving wheel. The driving wheel and the auxiliary clamping wheels are respectively on the upper and lower sides of the cable, and the driving wheel and the auxiliary clamping wheels are both in contact with the cable.

[0018] Further, two second hydraulic cylinders are fixedly arranged on the power storage box. The second hydraulic cylinders are arranged along the axial direction of the cable. The two second hydraulic cylinders are respectively between the first support frame and the second support frame. And the extending ends of the two second hydraulic cylinders are respectively fixedly connected to the first support frame and the second support frame.

[0019] The beneficial effects of the present invention are as follows: For an ice removal device for a transmission line in a cold region of the present invention, through the provided scraping mechanism and auxiliary mechanism, the two scraping semi - rings are clamped tightly with the cable, and then the walking mechanism drives the housing to move on the cable, and the scraping semi - rings remove the ice layer on the cable. The auxiliary mechanism is first in the first working mode, the first articulated rod rotates forward, and the first hydraulic cylinder is in the longest state, thereby driving the clamping block to move forward and move towards the cable until the clamping block clamps the cable and preliminarily breaks the ice layer. Then the auxiliary mechanism is in the second working mode, the first articulated rod rotates reversely, the first hydraulic cylinder shortens, and the clamping block is stationary, thereby driving the housing to move forward further, thus increasing the forward speed of the housing, and further improving the ice - breaking effect of the scraping semi - rings. Then the first working mode and the second working mode of the auxiliary mechanism are continuously and alternately switched.

[0020] When the ice layer is relatively soft, when the auxiliary mechanism is in the second working mode, it increases the forward speed of the housing, thereby accelerating the cleaning of the ice layer. When the ice layer is relatively hard, when the auxiliary mechanism is in the second working mode, due to the relatively hard ice layer, it is not easy for the scraping semi - rings to break the ice layer. Therefore, the auxiliary mechanism assists the housing to move forward, providing additional power for the scraping semi - rings to scrape the ice layer, thus helping to improve the crushing efficiency and preventing the entire device from being stuck by the ice layer.

[0021] When the ice layer is relatively thin, the clamping block needs to move a longer distance to contact the ice layer on the cable. Therefore, when the auxiliary mechanism is in the first working mode, the first articulated rod will drive the clamping block to move forward farther, so the distance between the first articulated rod and the clamping block along the axial direction of the cable is farther. Then the auxiliary mechanism is in the second working mode, and the distance that the auxiliary mechanism assists the housing to move forward increases, further increasing the forward speed of the housing and improving the efficiency of cleaning the ice layer.

[0022] When the ice layer is relatively thick, the clamping block only needs to move a short distance to contact the ice layer on the cable. After the clamping block is clamped tightly with the thick ice layer, the clamping block no longer moves. Therefore, the distance that the auxiliary mechanism drives the clamping block to move forward is short, and the distance between the first articulated rod and the clamping block in the axial direction of the cable is close. Then the auxiliary mechanism is in the second working mode, and the distance that the auxiliary mechanism assists the housing to move forward is short. Therefore, the auxiliary mechanism divides the ice layer on the cable into multiple ice layer segments with shorter distances, making it easier for the scraping semi - rings to scrape the ice layer and preventing the scraping semi - rings from being stuck.

Specific embodiments

[0032] Referring to Figures 1 to 7 As shown, an ice removing device for a transmission line in a cold region provided by an embodiment of the present invention includes a housing, a traveling mechanism, a scraping mechanism, and an auxiliary mechanism. The scraping mechanism includes a scraping assembly. The scraping assembly includes two scraping semi-rings 200 with concave surfaces facing each other. The scraping semi-rings 200 are arranged on the housing, and the concave surfaces of the scraping semi-rings 200 are in contact with the outer peripheral wall of the cable 600. The traveling mechanism drives the housing to move on the cable 600.

[0033] The auxiliary mechanism includes a driving assembly and two clamping assemblies. The two clamping assemblies are distributed along the circumferential direction of the cable 600. Each clamping assembly includes a clamping block 330 and a first hinge rod 300, a second hinge rod 310, and a first hydraulic cylinder 320 located on the same reference plane parallel to the cable 600. One end of the first hinge rod 300 is rotatably arranged on the housing. One end of the second hinge rod 310 is hinged to the other end of the first hinge rod 300, and the clamping block 330 is rotatably arranged at the other end of the second hinge rod 310. One end of the first hydraulic cylinder 320 is rotatably arranged on the housing, and the other end of the first hydraulic cylinder 320 is hinged to the second hinge rod 310.

[0034] The auxiliary mechanism has a first working mode and a second working mode. In the first working mode of the auxiliary mechanism, the first hydraulic cylinder 320 is at its longest, and the first articulated rod 300 rotates forward, thereby driving the clamping block 330 to move forward and move towards the cable 600 until the cable 600 is clamped. Forward refers to the front side in the moving direction of the housing. In the second working mode of the auxiliary mechanism, the first articulated rod 300 rotates reversely, and the first hydraulic cylinder 320 shortens, causing the clamping block 330 to be stationary, and then driving the housing to move forward. The drive assembly controls the forward and reverse rotation of the first articulated rod 300 to control the alternating conversion between the first working mode and the second working mode.

[0035] Clamp the two scraping half-rings 200 and the cable 600 tightly, and then drive the housing to move on the cable 600 through the traveling mechanism, and the scraping half-rings 200 remove the ice layer on the cable 600. The auxiliary mechanism is first in the first working mode, the first articulated rod 300 rotates forward, and the first hydraulic cylinder 320 is in the longest state, thereby driving the clamping block 330 to move forward and move towards the cable 600 until the clamping block 330 clamps the cable 600 and preliminarily breaks the ice layer. Then the auxiliary mechanism is in the second working mode, the first articulated rod 300 rotates reversely, the first hydraulic cylinder 320 shortens, the clamping block 330 is stationary, and then drives the housing to move forward further, thereby increasing the forward speed of the housing, and then improving the ice-breaking effect of the scraping half-rings 200. Then the first working mode and the second working mode of the auxiliary mechanism are continuously and alternately switched.

[0036] When the ice layer is relatively soft, when the auxiliary mechanism is in the second working mode, the forward speed of the housing is increased, thereby accelerating the cleaning of the ice layer.

[0037] When the ice layer is relatively hard, when the auxiliary mechanism is in the second working mode, due to the relatively hard ice layer, it is not easy for the scraping half-rings 200 to break the ice layer. Therefore, the auxiliary mechanism assists the housing to move forward, providing additional power for the scraping half-rings 200 to scrape the ice layer. This helps to improve the crushing efficiency and prevent the entire device from being stuck by the ice layer.

[0038] When the ice layer is relatively thin, the clamping block 330 needs to move a longer distance to contact the ice layer on the cable 600. Therefore, when the auxiliary mechanism is in the first working mode, the first articulated rod 300 will drive the clamping block 330 to move forward farther, so the distance between the first articulated rod 300 and the clamping block 330 along the axial direction of the cable 600 is farther. Then the auxiliary mechanism is in the second working mode, and the distance that the auxiliary mechanism assists the housing to move forward increases, further increasing the forward speed of the housing and improving the efficiency of cleaning the ice layer.

[0039] When the ice layer is thick, the clamping block 330 only needs to move a short distance to contact the ice layer on the cable 600. After the clamping block 330 is clamped with the thick ice layer, the clamping block 330 no longer moves. Therefore, the distance that the auxiliary mechanism drives the clamping block 330 to move forward is short, and the distance between the first hinge rod 300 and the clamping block 330 in the axial direction of the cable 600 is close. Then the auxiliary mechanism is in the second working mode again, and the distance that the auxiliary mechanism assists the housing to move forward is short. Therefore, the auxiliary mechanism divides the ice layer on the cable 600 into multiple ice layer segments with short distances, so that it is easier for the scraping half-ring 200 to scrape off the ice layer and prevent the scraping half-ring 200 from being stuck.

[0040] In this embodiment, two connecting frames 220 are arranged on the housing. The two connecting frames 220 are respectively located on both sides in the circumferential direction of the cable 600. The direction in which the two connecting frames 220 are sequentially distributed is the first direction, and the first direction is the horizontal direction. The connecting frame 220 can slide along the first direction. A first arc groove is formed in each connecting frame 220, and the concave surface of the first arc groove faces the cable 600. Each scraping half-ring 200 is rotatably arranged in a first arc groove. A rack 201 is fixedly arranged on the convex surface of each scraping half-ring 200. A first motor 230 is fixedly arranged on each connecting frame 220, and a first gear 240 is fixedly arranged on the output shaft of the first motor 230. The first gear 240 meshes with the rack 201.

[0041] In this embodiment, the scraping mechanism further includes a removing component. The removing component includes a plurality of ice-breaking cones 210. The two ends of the ice-breaking cone 210 are the first end and the second end. The first end of the ice-breaking cone 210 is fixedly arranged on one side of the scraping half-ring 200, and the second end of the ice-breaking cone 210 is used to contact the ice layer on the cable 600. The plurality of ice-breaking cones 210 are sequentially distributed along the circumferential direction of the scraping half-ring 200. The ice-breaking cone 210 is inclined, and there is an included angle between the ice-breaking cone 210 and the plane where one side of the scraping half-ring 200 is located in the axial direction of the cable 600. And along the rotation direction of the scraping half-ring 200, the first end of the ice-breaking cone 210 is located behind the second end. The ice-breaking cone 210 is inclined, which has an effect of removing the ice layer, thereby improving the ice-breaking effect.

[0042] In this embodiment, a clamping groove 202 is formed at one end of each scraping half-ring 200, and a clamping block is arranged at the other end of each scraping half-ring 200. Each clamping block is arranged in the clamping groove 202 on another scraping half-ring 200.

[0043] After the two scraping half-rings 200 are in contact with each other, the clamping block is clamped into the clamping groove 202. The first motor 230 is started, and the first motor 230 drives the scraping half-ring 200 to rotate through the first gear 240. When the scraping half-ring 200 rotates, it drives the plurality of ice-breaking cones 210 to rotate synchronously.

[0044] In this embodiment, the housing includes a power storage box 100, a first support frame 110, and a second support frame 120. The first support frame 110 and the second support frame 120 are slidably arranged on the power storage box 100 along the axial direction of the cable 600. And the first support frame 110 and the second support frame 120 are sequentially distributed along the axial direction of the cable 600. The first support frame 110 is located on the front side of the housing's moving direction relative to the second support frame 120. Both the scraping mechanism and the auxiliary mechanism are arranged on the first support frame 110.

[0045] In this embodiment, the scraping mechanism further includes a transmission component, and the transmission component includes a second motor 250 and a bidirectional screw 260. The second motor 250 is arranged on the first support frame 110, and the bidirectional screw 260 is fixedly connected to the output shaft of the second motor 250. The bidirectional screw 260 is arranged along the first direction. The connecting frames 220 are in spiral transmission cooperation with the bidirectional screw 260, and the spiral cooperation directions of the two connecting frames 220 and the bidirectional screw 260 are opposite.

[0046] When the second motor 250 is started, the second motor 250 drives the bidirectional screw 260 to rotate forward. When the bidirectional screw 260 rotates forward, it drives the two connecting frames 220 to approach each other.

[0047] In this embodiment, a turbine 340 is fixedly arranged at one end of each first hinge rod 300 connected to the housing. The auxiliary mechanism further includes a driving component, and the driving component includes a third motor 350 and a worm 360. The third motor 350 is fixedly arranged on the first support frame 110, and the worm 360 is fixedly connected to the output shaft of the third motor 350. The worm 360 meshes with the two turbines 340.

[0048] When the third motor 350 rotates forward, it drives the worm 360 to rotate forward, and drives the first hinge rod 300 to rotate forward through the turbine 340. When the third motor 350 rotates reversely, it drives the worm 360 to rotate reversely, and drives the first hinge rod 300 to rotate reversely through the turbine 340.

[0049] In this embodiment, each clamping block 330 includes a connecting rod and a clamping head. The connecting rod is arranged vertically, and the upper end of the connecting rod is rotatably connected to the second hinge rod 310. The clamping head is fixedly arranged at the lower end of the connecting rod. Each clamping head is provided with a second arc groove 331, and the concave surface of the second arc groove 331 faces the cable 600. A plurality of convex blocks 332 are fixed in the second arc groove 331, and the convex blocks 332 are in contact with the cable 600. When the two clamping blocks 330 clamp the cable 600 and the convex blocks 332 contact the ice layer, the convex blocks 332 have a crushing effect on the ice layer.

[0050] In this embodiment, two auxiliary frames 400 are rotatably arranged on both the first support frame 110 and the second support frame 120. The two auxiliary frames 400 are arranged in sequence along the axial direction of the cable 600. A torsion spring is arranged at the rotational connection of each auxiliary frame 400 and the first support frame 110 or the second support frame 120.

[0051] The traveling mechanism includes two traveling components, which are respectively arranged on the first support frame 110 and the second support frame 120. Each traveling component includes a fourth motor 410, a driving wheel 420, and two auxiliary clamping wheels 430. The axial directions of the driving wheel 420 and the auxiliary clamping wheels 430 are both arranged along the first direction. The two driving wheels 420 are respectively rotatably arranged on the first support frame 110 and the second support frame 120. Each auxiliary clamping wheel 430 is rotatably arranged on an auxiliary frame 400, and the auxiliary clamping wheel 430 is located below the driving wheel 420. The driving wheel 420 and the auxiliary clamping wheels 430 are respectively located on the upper and lower sides of the cable 600, and both the driving wheel 420 and the auxiliary clamping wheels 430 are in contact with the cable 600. The fourth motor 410 is fixedly arranged on the housing. The output shaft of each fourth motor 410 is fixedly connected to a driving wheel 420.

[0052] Install the housing on the cable 600, and make the driving wheel 420 and the auxiliary clamping wheels 430 contact the cable 600. Start the fourth motor 410, and the fourth motor 410 drives the driving wheel 420 to rotate. When the driving wheel 420 rotates, it drives the housing to move forward.

[0053] In this embodiment, two second hydraulic cylinders 500 are fixedly arranged on the power storage box 100. The second hydraulic cylinders 500 are arranged along the axial direction of the cable 600. The two second hydraulic cylinders 500 are respectively located between the first support frame 110 and the second support frame 120. And the extending ends of the two second hydraulic cylinders 500 are respectively fixedly connected to the first support frame 110 and the second support frame 120.

[0054] During operation, start the second hydraulic cylinders 500, and the second hydraulic cylinders 500 extend, so that the first support frame 110 and the second support frame 120 move away from each other. When the work is finished, the second hydraulic cylinders 500 contract, so that the first support frame 110 and the second support frame 120 move closer to each other, thus facilitating storage.

[0055] Working process: Install the housing on the cable 600, and make the driving wheel 420 and the auxiliary clamping wheels 430 contact the cable 600. Start the fourth motor 410, and the fourth motor 410 drives the driving wheel 420 to rotate. When the driving wheel 420 rotates, it drives the housing to move forward. In the initial state, the two scraping half-rings 200 are far apart and not buckled with each other.

[0056] Start the second motor 250. The second motor 250 drives the bidirectional screw 260 to rotate forward. When the bidirectional screw 260 rotates forward, it drives the two connecting frames 220 to approach each other. Until the two scraping half-rings 200 come into contact with each other, the clamping blocks on the scraping half-rings 200 enter the card slots 202 on the other scraping half-ring 200. Start the first motor 230. The first motor 230 drives the scraping half-ring 200 to rotate through the first gear 240.

[0057] During the process of the housing moving along the cable 600, the scraping half-ring 200 scrapes the ice layer on the cable 600. At the same time, when the scraping half-ring 200 rotates, it drives a plurality of ice-breaking cones 210 to rotate synchronously. Since the ice-breaking cones 210 are inclined, when the ice-breaking cones 210 rotate, they have the effect of peeling off the ice layer, thereby improving the ice-breaking effect on the ice layer.

[0058] At the same time, start the third motor 350. The auxiliary mechanism is first in the first working mode. The third motor 350 rotates forward first. When the third motor 350 rotates forward, it drives the worm 360 to rotate forward, and then drives the first hinge rod 300 to rotate forward through the turbine 340. When the first hinge rod 300 rotates forward, at this time the first hydraulic cylinder 320 is stationary. The first hinge rod 300 drives the clamping block 330 to move towards the direction close to the cable 600 through the second hinge rod 310, and the clamping block 330 moves forward until the clamping block 330 clamps the cable 600 to perform preliminary ice breaking.

[0059] After that, the auxiliary mechanism is in the second working mode, so that the third motor 350 rotates in the reverse direction. The third motor 350 drives the first hinge rod 300 to rotate in the reverse direction. When the first hinge rod 300 rotates in the reverse direction, start the first hydraulic cylinder 320 at the same time, and the first hydraulic cylinder 320 shortens. When the first hinge rod 300 rotates in the reverse direction, there is a tendency to drive the clamping block 330 to move away from the cable 600 through the second hinge rod 310. And the shortening of the first hydraulic cylinder 320 has a force to restrict the clamping block 330 from moving away from the cable 600, so the clamping block 330 remains stationary.

[0060] When the clamping block 330 is stationary, the rotation of the first hinge rod 300 shortens the distance between the first hinge rod 300 and the clamping block 330. Then the first hinge rod 300 drives the first support block to move forward further, thereby increasing the forward speed of the housing, and then improving the ice-breaking effect of the scraping half-ring 200. Then the first working mode and the second working mode of the auxiliary mechanism are continuously alternately switched.

[0061] When the ice layer is softer, when the auxiliary mechanism is in the second working mode, it increases the forward speed of the housing, thereby accelerating the cleaning of the ice layer and improving the efficiency of cleaning the ice layer, which is more time-saving.

[0062] When the ice layer is hard and the auxiliary mechanism is in the second working mode, since the ice layer is hard, it is not easy for the scraping half-ring 200 to break the ice layer, so the housing is not easy to move forward. Therefore, the auxiliary mechanism assists the housing to move forward, providing additional power for the scraping half-ring 200 to scrape the ice layer. When the scraping half-ring 200 rotates, the ice-breaking cone 210 rotates synchronously. Since the ice-breaking cone 210 is inclined, after being squeezed by the hard ice layer, the ice-breaking cone 210 can have a peeling force on the ice layer. Therefore, when the ice-breaking cone 210 rotates, it has a peeling effect on the ice layer. At the same time, the auxiliary mechanism gives the ice-breaking cone 210 additional power to break the ice layer, which helps to improve the breaking efficiency and prevent the entire device from being stuck by the ice layer.

[0063] When the ice layer is thin, the clamping block 330 needs to move a longer distance to contact the ice layer on the cable 600. Therefore, when the auxiliary mechanism is in the first working mode, the first hinge rod 300 will drive the clamping block 330 to move forward farther, so the distance between the first hinge rod 300 and the clamping block 330 along the axial direction of the cable 600 is farther. Then, when the auxiliary mechanism is in the second working mode, the distance that the auxiliary mechanism assists the housing to move forward increases, further increasing the forward speed of the housing and improving the efficiency of ice cleaning.

[0064] When the ice layer is thick, the clamping block 330 only needs to move a short distance to contact the ice layer on the cable 600. After the clamping block 330 contacts the ice layer, since the convex block 332 is provided on the clamping block 330, when the convex block 332 on the clamping block 330 is clamped with the thick ice layer, the clamping block 330 no longer moves. Therefore, the distance that the auxiliary mechanism drives the clamping block 330 to move forward is short, and the distance between the first hinge rod 300 and the clamping block 330 in the axial direction of the cable 600 is close. And when the convex block 332 on the clamping block 330 contacts the ice layer, the convex block 332 also has a breaking effect on the ice layer.

[0065] Then, when the auxiliary mechanism is in the second working mode again, the distance that the auxiliary mechanism assists the housing to move forward is short. Therefore, the auxiliary mechanism divides the ice layer on the cable 600 into multiple ice layer segments with short distances, making it easier for the scraping half-ring 200 to scrape the ice layer and preventing the scraping half-ring 200 from being stuck.

[0066] The above description is only the specific implementation manner of the present invention, and various examples do not constitute a limitation to the essence of the present invention.
