A first end of the first support rod 10 is hinged to the drive ring and a second end of the first support rod 10 is located at the front side of the drive ring and outside the layer of ice and snow on the cable 2. One side of the first support rod 10 facing the cable 2 is provided with a sliding groove extending along the length direction thereof, a plurality of positioning blocks 19 are arranged inside the sliding groove, the positioning blocks 19 are sequentially connected through a first elastic member, the positioning block 19 on one side close to the drive ring is fixedly mounted on the first support rod 10, the rest of the positioning blocks 19 are slidably arranged along the sliding groove, and specifically, the first elastic member is a return spring 15. The end face, far away from the cable 2, of the ice breaking blade 12 is provided with a rotating wheel 13, the rotating wheel 13 is rotatably installed in a positioning block 19 around the axis of the rotating wheel 13, a second elastic element for enabling the ice breaking blade 12 and the cable to be coplanar is sleeved between the rotating wheel 13 and the positioning block 19, and specifically, the second elastic element is a torsion spring. The travel wheel 20 is disposed inside the drive ring, and the front end of the travel wheel 20 is on the counterclockwise side of the rear end as viewed in the first direction, so that the travel wheel 20 drives the drive ring to move forward when the drive ring rotates in the clockwise direction as viewed in the first direction.
In use, the drive ring is rotated by the drive mechanism in a clockwise direction as viewed in the first direction and is moved forwardly by the travelling wheel 20. When the ice breaking blade 12 contacts the ice layer, the ice breaking blade 12 of the whole ice breaking mechanism breaks the ice and snow layer 1.
If ice and snow 1 with high hardness is encountered, the resistance of the ice breaking blade 12 rotating along with the driving ring is greater than the torsion of the torsion spring, the ice breaking blade 12 can deflect relative to the positioning block 19 through the rotating wheel 13, so that the front end is positioned on the counterclockwise side of the rear end when the ice breaking blade 12 is seen along the first direction, the broken ice and snow 1 can be conveniently discharged, the broken ice and snow 1 is prevented from being accumulated to be secondarily frozen on the ice breaking blade 12, the deicing efficiency is ensured, the ice breaking blade 12 is stressed inwards along the radial direction of the driving ring after the ice breaking blade 12 inclines, and further, each ice breaking mechanism is enabled to be arranged more tightly.
In one embodiment, as shown in fig. 3 and 4, there are two drive rings, two drive rings are connected by a plurality of telescopic rods 14 to drive one drive ring to rotate when the other drive ring rotates, and in the first direction, the drive ring at the front side is the first drive ring 11 and the drive ring at the rear side is the second drive ring 6.

One end of the second support rod 4 is rotatably connected to the second drive ring 6, and the other end is rotatably connected to the second end of the first support rod 10. The adjustment assembly is used to cause the angle of inclination of the travel wheels 20 to change as the two drive rings move away to reduce the speed of travel of the drive rings.
If meeting ice and snow 1 with high hardness, the resistance of the first driving ring 11 to move is increased, the force required by the end of the ice breaking blade 12 far away from the cable 2 to break the ice and snow 1 is also increased, the ice breaking blade 12 drives the front end of the first supporting rod 10 to turn outwards, so that the first driving ring 11 moves forwards relative to the second driving ring 6, and the spring 5 stretches to enable the ice breaking blade 12 to have enough breaking force. The arrangement of the adjusting assembly causes the inclination angle of the travelling wheels 20 to change when the two driving rings are far away, so as to reduce the travelling speed of the driving rings and adapt the ice breaking speed of the ice breaking blade 12.
In one embodiment, the blade edges of the ice knives 12 extend outward along the radial direction of the cable 2 from the side close to the drive ring to the side far from the drive ring, the heights of the ice knives 12 of each ice breaking mechanism are gradually reduced from back to front along the first direction and the direction perpendicular to the first support rod, and the height of each ice knife 12 is gradually reduced from back to front, so that the ice and snow 1 on the cable 2 can be cut conveniently.
In one embodiment, the travelling wheels 20 are more than three and are evenly distributed around the circumference of the cable 2, so that the driving ring can rotate more stably.
In one embodiment, as shown in FIG. 3, the adjustment assembly includes a fixed block, a gear 16, and a rack 18. The fixed block is fixedly mounted to the first drive ring 11. The gear 16 is rotatably mounted to the fixed block about its axis. A connecting shaft is fixedly inserted in the middle of the gear 16, the connecting shaft extends along the radial direction of the driving ring, one end of the connecting shaft, which faces the axis of the driving ring, is connected with a plurality of supporting shafts, the front ends of the supporting shafts are positioned on the clockwise side of the rear ends in the direction seen from the first direction, and the traveling wheel 20 is rotatably sleeved on the supporting shafts. One end of the rack 18 is mounted to the second drive ring 6 so that the drive gear 16 rotates when the distance between the two drive rings changes, and the distance in the first direction between the two ends of the travel wheel 20 decreases when the two drive rings are moved away from each other, so that the speed at which the drive rings travel decreases.
In one embodiment, the rotating wheel 13 is connected to the front side of the middle part of the outer end surface of the ice-breaking blade 12 through a connecting column along the advancing direction of the driving ring and the radial direction of the driving ring, so as to smoothly deflect to the counterclockwise side with the front end at the rear end when the ice-breaking blade 12 is subjected to large resistance.
In one embodiment, as shown in fig. 3 and 5, a travelling cable deicing device further includes a counterweight housing, with the drive ring rotatably disposed relative to the counterweight housing, and the counterweight housing is held under the drive ring by gravity. The drive mechanism comprises a toothed ring 17, a motor 7 and a drive gear. The toothed ring 17 is arranged coaxially with the drive ring and is fixedly connected to the second drive ring 6. The motor 7 is mounted on the counterweight shell. The driving gear is fixedly sleeved on an output shaft of the motor 7 and is meshed with the gear ring 17. The motor 7 rotates the second drive ring 6 via the drive gear and the toothed ring 17.
In one embodiment, as shown in fig. 2, the weight housing comprises a fixed frame 8 and a weight 9 connected to each other. The outer periphery of the second drive ring 6 is fitted with a bearing, and the upper part of the fixed frame 8 is connected with the lower part of the outer ring of the bearing. The motor 7 is arranged in the fixed frame 8, and the weight 9 is connected to the lower end face of the fixed frame 8, so that the balance weight of the fixed frame 8 is increased, namely the stability of the motor 7 is increased. The utility model provides a marching type cable defroster still includes firm ring 3, firm ring 3 and fixed frame 8 fixed connection, and the outside of cable 2 is located to the cover, avoids influencing deicing effect because of two driving rings are uneven in the horizontal direction atress for stability is stronger when marching type cable defroster walks.
In one embodiment, the travelling cable deicing device is placed on a telegraph pole when not in use, the load of a cable 2 is not increased, the second driving ring 6 and the first driving ring 11 are sleeved on the cable 2 when in use, and the motor 7 is turned on when the electric wire is frozen in winter to perform deicing work (as shown in figure 1).
After the motor 7 is started, the motor 7 drives the second driving ring 6 to rotate clockwise around the axis thereof in the direction from back to front through the driving gear and the gear ring 17, the second driving ring 6 drives the first driving ring 11 to rotate through the plurality of telescopic rods 14, the second driving ring 6 and the first driving ring 11 drive the traveling wheel 20 to rotate when rotating, and the traveling wheel 20 drives the second driving ring 6 and the first driving ring 11 to travel forward when rotating. When the ice-breaking blades 12 on the first driving ring 11 contact with an ice layer, the whole ice-breaking mechanism is stressed, the outer ends of the first supporting rods 10 are expanded outwards under the action of a forward resistance, the outer ends of the first supporting rods 10 are expanded outwards, and the forward movement of the second driving ring 6 is limited under the action of the second supporting rod 4, so that the first driving ring 11 moves forwards relative to the second driving ring 6, the spring 5 is stretched, and when the acting force of the ice-breaking blades 12 on the second supporting rod 4 is the same as the acting force of the spring 5 on the second supporting rod 4, the second supporting rod 4 and the first supporting rod 10 reach a balanced state. The first driving ring 11 is rotated to break the ice and snow 1 on the cable 2 by the ice breaking blade 12 (as shown in fig. 4).
When encountering ice and snow 1 with high hardness, the advancing resistance of the first driving ring 11 and the rotation resistance of the ice breaking blade 12 along with the first driving ring 11 are increased, and after the rotation resistance of the ice breaking blade 12 along with the first driving ring 11 is greater than the torsion of the torsion spring, the ice breaking blade 12 can deflect relative to the positioning block 19 through the rotating wheel 13, so that the front end is positioned on the anticlockwise side of the rear end, the positioning block 19 can slide backwards along the sliding groove, and in the process, the ice breaking blade 12 is pressed inwards, so that each ice breaking mechanism is arranged more tightly. Since the resistance of the forward movement of the first drive ring 11 is increased at this time, the force required for the forward movement of the ice-breaking blade 12 is also increased, and the ice-breaking blade 12 further drives the front end of the first support rod 10 to turn outwards, so that the first drive ring 11 further moves forward relative to the second drive ring 6, and the spring 5 is further stretched, so that the front end of the ice-breaking blade 12 has sufficient breaking force. When the distance between the second driving ring 6 and the first driving ring 11 is increased, the gear 16 is driven by the rack 18 to rotate, the gear 16 drives the support shaft to rotate by a certain angle through the connecting shaft, so that the support shaft is further inclined, that is, the front end and the rear end of the travelling wheel 20 in the first direction are closer to each other, so as to reduce the travelling speed of the first driving ring 11, adapt to the deicing speed of the ice breaking blade 12, and ensure that the deicing is continued (as shown in fig. 6).
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
