With the gradual acceleration of the urbanization process, urban planning tends to be more modern. In the urban construction process, the erection of cables becomes the lowest construction requirement. Therefore, the cable can be used for transmitting electric energy far away from thousands of households, and the purpose of power transmission is achieved. In current cable use, for the injury that reduces personnel and electrocute, the staff often erects the cable on the high altitude, when guaranteeing that electric power can transport, reduces the risk that personnel electrocute. In cold winter, particularly in rainy and snowy weather, when the rain and snow fall on the cable, the rain and snow cannot fall down in time, and when the weather temperature is low, the rain and snow are easily attached to the side wall of the cable, and gradually form an ice cone below the cable along with the passage of time. Because the cable frame is located the high altitude, the staff can't be timely make the clearance. The weight of the cable is increased along with the gradual increase of the ice cones condensed on the cable, and the cable is easy to break along with the gradual increase of the weight of the cable because the two ends of the cable are fixed on the bracket in one section of the cable.

In order to ensure the conductive transmission efficiency of the cable and the safety during the power transmission process, all the parts mentioned in the above embodiments are made of insulating materials except the conductor 200.

With the above embodiments, the usage principle and the working process of the present invention are as follows:

a deicing device for urban high-voltage cables is formed by fixedly connecting a plurality of units as shown in figure 1, and every two adjacent units are fixedly connected through a connecting piece. When power is transmitted, an appropriate length is cut according to the length of a required transmission distance, and when the weather of rain and snow is encountered in winter, ice is guided to be condensed at the lower end of the insulation case 100 by the structure of the insulation case 100.

In an initial state, when the cable is not frozen, the conductor 200 and the insulating shell 100 synchronously swing under the action of wind for a long-distance cable, in rainy and snowy weather, an ice layer gradually condenses at the lower end of the insulating shell 100, the weight of the lower end of the insulating shell 100 gradually increases along with the gradual increase of the ice layer, under the action of wind, the cable swings left and right to enable the conductor 200 and the insulating shell 100 to rotate relatively, the inner sides of a first rotating wheel 520 and a second rotating wheel 530 arranged between the insulating shell 100 and the cable are in threaded connection with the conductor 200, the outer side walls of the first rotating wheel 520 and the second rotating wheel 530 are in unidirectional rotatable and slidable connection with the insulating shell 100, when the insulating shell 100 and the conductor 200 rotate relatively, the first rotating wheel 520 and the second rotating wheel 530 rotate synchronously and gradually approach each other to extrude the energy storage spring 510 to enable the energy storage spring 510 to store the energy, and as time goes on, the energy storage spring 510 stores the energy to the maximum state.

In the process of storing power by the energy storage spring 510, the two driving rods 440 respectively slide left and right in the third limiting groove 130 under the driving of the annular grooves 540 formed on the first rotating wheel 520 and the second rotating wheel 530, when the energy storage spring 510 is about to store power to the limiting position, the protrusions 441 arranged on the driving rods 440 gradually abut against the pushing grooves 461 of the blocking rods 460, and when the driving rods 440 continue to slide, the driving rods 440 slide forward to release the limiting on the sliding rods 450, because the ice on the outer sides of the first ice breaking plate 310 and the second ice breaking plate 320 at the lower end of the insulating housing 100 has a certain gravity, and the cable has a certain centrifugal force in the swinging process, because the lower end of the sliding rod 450 is fixedly connected with the connecting rod 470, the lower end of the connecting rod 470 rotatably connects the hinge shaft of the first ice breaking plate 310 and the second ice breaking plate 320 and the hinge shaft of the first pushing plate 340 and the second pushing plate 350. The sliding bar 450 slides down along the second limiting groove 120 by gravity and centrifugal force of ice, and at the same time, the blocking bar 460 is prevented from returning to the initial state. The sliding rod 450 is provided with a sliding rail with an upward opening, a connection block is arranged between the sliding rail and the annular groove 540, the connection block can slide on the sliding rail and can slide on the annular groove 540, so that the sliding rod 450, the first rotating wheel 520 and the second rotating wheel 530 can synchronously move in the vertical direction, when the sliding rod 450 slides along the second limiting groove 120, the fixed part and the sliding part of the first rotating wheel 520 and the second rotating wheel 530 are pulled to be separated, the fixed part of the first rotating wheel 520 and the second rotating wheel 530 is fixedly arranged on the insulating shell 100, the conductor 200 slightly slides downwards in the connection part under the action of gravity, so that the first rotating wheel 520 and the second rotating wheel 530 are separated from being in threaded fit with the conductor 200, and the two driving rods 440 are driven by the first rotating wheel 520 and the second rotating wheel 530 to slide downwards, so that the two driving rods 440 are simultaneously meshed with the transmission gear 420. With the releasing force of the energy storage spring 510, the first rotating wheel 520 and the second rotating wheel 530 are pushed to move away from each other, and at the same time, the driving rod 440 is driven to slide, since the driving rod 440 is engaged with the rotating gear to drive the rotating gear to rotate, the rotating gear is in threaded connection with the driving rod 480, when the rotating gear rotates, the driving rod 480 slides downward to press the sliding block 410 to slide downward, the lower end of the sliding block 410 is respectively connected with the first pushing plate 340 and the second pushing plate 350 in a rotating manner, with the downward sliding of the sliding block 410, the first pushing plate 340 and the second pushing plate 350 move away from each other, so that the pushing blocks 360 fixedly arranged on the first pushing plate 340 and the second pushing plate 350 extrude the icebreaking blocks 330 in abutment with each other to rotate outward, the thinner ice attached to the upper ends of the first icebreaking plate 310 and the second icebreaking plate 320 is broken, the angles of the pushing blocks 360 are gradually identical to the angles of the icebreaking blocks 330, at this time, the pushing blocks 360 do not push the icebreaking blocks 330 any more, with the sliding block 410 continuing to slide downward, the first pushing plate 340 abuts against the middle of the first icebreaking plate 310 and the second pushing plate 350, and the second icebreaking plate 320, and the second pushing plate 320 continues to push the icebreaking plates 320 by the centrifugal force of the icebreaking plates 320, and the ice breaking plates 320, and the second pushing plates 340 and the second pushing plates 320, and the icebreaking plates 320, and the ice breaking plates 320 are further pushing plates 320. Under the action of the return spring 430 arranged between the transmission gear 420 and the sliding block 410, the initial state is restored under the combined action of a first torsion spring between the first ice breaking plate 310 and the second ice breaking plate 320, a second spring at the hinge joint of the first pushing plate 340 and the second pushing plate 350, a second torsion spring at the rotary joint of the ice breaking block 330 and the first ice breaking groove, a third spring between the fixed part and the sliding part of the first driving wheel and the second rotating wheel 530, and a fourth spring 490 between the insulating shell 100 and the blocking rod.

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.
