[0051] In an electric ice peeling device based on a high-voltage cable of the present invention, a power supply device and a camera assembly are also provided and are both installed in a device housing 1. The power supply device can provide motion power for a travel transmission mechanism 3, a rotary motion mechanism 4 and an ice peeling mechanism 5. The camera assembly can monitor the travel state of the travel transmission mechanism 3 and the rotary ice peeling operation of the distribution cable in real time to improve the convenience and effect of operation.

[0052] The working principle of the live ice stripping device based on high-voltage cable of the present invention is as follows: (1) The drone is docked with the device housing 1 through the drone docking mechanism 2, and the entire live ice stripping device based on high-voltage cables is lifted in pairs under the action of the drone. At the same time, the travel transmission mechanism 3, the rotary motion mechanism 4, the ice stripping mechanism 5 and the motion balance mechanism 6 are ready for the power distribution cable engagement, including: the two travel V-shaped wheels 36 of the travel transmission mechanism 3 move in opposite directions and open under the control of the travel wheel adjustment steering gear 37; the small ring segment gear of the annular gear 43 of the rotary motion mechanism 4 rotates to a low position or close to a low position, and the gap of the small ring segment gear and the gap of the gear fixing frame 44 are opened; the two symmetrically arranged ice stripping components 51 of the ice stripping mechanism 5 are in left and right positions under the rotation of the rotary motion mechanism 4 and move in opposite directions and open; the gap of the snap ring 62 of the motion balance mechanism 6 coincides with the gap of the spiral ring 61.

[0053] (2) After the drone hoists the entire live ice stripping device based on high-voltage cables to the top of the distribution cable, it gradually descends, so that the distribution cable is engaged with the cable engagement recess 11 of the device housing 1. At the same time, the distribution cable is also synchronously engaged with the two limit rods 32 and the limit blocks 33 of the travel transmission mechanism 3; it is also synchronously engaged with the inside of the annular gear 43 of the rotary motion mechanism 4, the inside of the clamping ring 62 and the spiral ring 61 of the motion balance mechanism 6, and between the arc recesses 513 of the two symmetrical ice stripping components 51 of the ice stripping mechanism 5.

[0054] (3) The travel transmission mechanism 3 starts the travel wheel adjustment steering gear 37 to drive the two travel V-shaped wheels 36 to move relative to each other and clamp the distribution cable; at this time, the distribution cable is located on the axis of the annular gear 43, the clamping ring 62, the spiral ring 61 and the center of the arc-shaped notches 513 of the two ice stripping components 51. Then, the UAV stops working, or controls the UAV to separate from the entire live ice stripping device based on the high-voltage cable, so as to realize the lifting operation of the entire live ice stripping device based on the high-voltage cable by the UAV.

[0055] (4) The driving pinion 45 of the rotary motion mechanism 4 rotates in the positive direction under the control of the motor, driving the gear fixing frame 44 to continuously rotate in the positive direction around the annular gear 43. At this time, the retaining ring 62 also rotates with the gear fixing frame 44 and performs a precession motion on the spiral ring 61, thereby driving the entire rotary motion mechanism 4 to slide forward on the motion mechanism slide rail set on the upper end surface of the device housing 1.

[0056] (5) During the continuous forward rotation of the gear fixing frame 44 of the rotating mechanism 4 around the annular gear 43, the ice peeling mechanism 5 installed on the rear end surface of the gear fixing frame 44 also rotates and moves forward continuously; at the same time, the two ice peeling components 51 of the ice peeling mechanism 5 are controlled by the pneumatic telescopic device 54 to slide relatively on the ice peeling component slide rail 52 and finally make the ice peeling tool 514 installed in the ice peeling component 51 come into contact with the ice attached to the distribution cable; during the continuous rotation and forward movement of the ice peeling mechanism 5, the ice attached to the distribution cable is peeled off by the ice peeling tool 514, thereby realizing the ice peeling operation of a certain distance on the distribution cable.

[0057] (6) After the rotating motion mechanism 4 and the ice peeling mechanism 5 rotate to the maximum distance, the two ice peeling components 51 of the ice peeling mechanism 5 are controlled by the pneumatic telescopic device 54 to slide back and forth on the ice peeling member slide rail 52 and keep the ice peeling tool 514 away from the distribution cable; the active pinion 45 of the rotating motion mechanism 4 rotates in the opposite direction under the control of the motor, driving the gear fixing frame 44 to continuously rotate in the opposite direction around the annular gear 43, and at this time, the retaining ring 62 also rotates in the opposite direction with the gear fixing frame 44 and rotates back on the spiral ring 61, thereby driving the entire rotating motion mechanism 4 to slide on the motion mechanism slide rail set on the upper end surface of the device housing 1 and return to the initial position.

[0058] (7) The travel motor 361 controls the travel V-shaped wheel 36 to rotate, so that the entire electric ice stripping device can move on the distribution cable by itself. After the entire live ice stripping device based on the high-voltage cable moves to the next target area to be de-iced on the distribution cable, steps (4) to (6) are repeated to realize the de-ice operation of the target area to be de-iced on the distribution cable.

[0059] (8) Similarly, after all ice stripping operations on the distribution cable are completed, the travel transmission mechanism 3, the rotary motion mechanism 4, the ice stripping mechanism 5 and the motion balancing mechanism 6 are controlled to separate from the distribution cable, and then the entire live ice stripping device based on the high-voltage cable is lifted off by a drone.

[0060] The present invention is an electric ice stripping device based on a high-voltage cable. Through the two travel transmission mechanisms 3 installed at the front and rear ends of the device housing 1 and the clamping cooperation with the distribution cable, the distribution cable can be clamped and moved by itself, and the travel efficiency is high; through the mutual cooperation of the rotary motion mechanism 4 and the ice stripping mechanism 5 arranged in the device housing 1, the ice on the distribution cable can be rotated and ice-stripped, which is easy to operate and has high de-icing efficiency; due to the heavy pressure caused by thick ice on the cable, the ice stripping operation can directly remove the ice layer through a targeted method; under extreme weather conditions, the ice stripping operation is not limited by the ambient temperature and can be carried out at any time, especially when facing a thick ice layer, the operation flexibility is higher; the ice layer removed by ice stripping will not quickly form frost again, which is conducive to the normal operation of the maintenance equipment and reduces the subsequent maintenance frequency.

[0061] The present invention has a compact structure, can realize live ice stripping operations on high-voltage distribution cables, has a high degree of automation, is simple and convenient to operate, has good controllability, saves time and effort, is safe and reliable, has high deicing efficiency, and has low energy consumption costs, and does not pollute the environment.

[0062] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
