The specific working process of the invention is as follows: this device adopts the mounting means of unmanned aerial vehicle hoist and mount when using, be equipped with unmanned aerial vehicle hoist and mount coupling assembling on the U-shaped plate 1, unmanned aerial vehicle adopts rigid connection in connecting with this device, accomplish this device of back unmanned aerial vehicle drive makes the electric wire that has the icicle enter into the support from the outside extrusion of pendulum rod 21 inside, this device extrusion pendulum rod 21 of unmanned aerial vehicle drive in this motion process, make first magnet 22 and second magnet 23 throw off along with the increase of extrusion force, the completion is thrown off the back, the electric wire enters into in the support, the lower extreme of pendulum rod 21 resets and realizes first magnet 22 and the mutual absorption of second magnet 23 under the action of gravity, the support reforms transform closed loop's rigid connection structure, this moment with U-shaped plate 1 from the top lock of electric wire on the electric wire.

The U-shaped plate 1 is driven to move on ice along the length direction of an electric wire from the ground through an insulating pull rope 17 by a worker through holding or connecting a driving device, a plurality of supporting rods 6 on a first belt 3 can be arranged in gaps among a plurality of icicles in the moving process, because the gaps among the icicles are not completely consistent, the distances among the icicles deviate, when the supporting rods 6 are contacted with the icicles and are not arranged in the gaps of the icicles, the supporting rods 6 are contacted with the icicles and are extruded, the end parts of the supporting rods 6 and the outer circular surfaces of the icicles are cambered surfaces, therefore, the extruding force can enable the supporting rods 6 to slide in a sliding groove 5 and enable the supporting rods to enter the icicles again, meanwhile, one of two first compression springs 24 on the supporting rods 6 is stressed by a pulling force, the two first compression springs 24 have the tendency of rebounding and the elastic potential energy, and when the supporting rods 6 move to be completely, the two first compression springs 24 are reset to the middle of the sliding groove, and the left and right swinging of the support rods 6 does not influence the meshing transmission between the support rods and the icicles to drive the first belt 3 to move due to the fact that the number of the support rods is large.

With the driving of the insulation pull rope 17, the U-shaped plate 1 moves to drive the roller 2 to rotate through the first belt 3 and the support rod 6, the roller 2 rotates to drive the second belt 7 to rotate, the rotation of the second belt 7 is transferred to the pressing wheel 8 on the second belt 7 through kinetic energy, the pressing wheel 8 rotates to drive the incomplete gear 9 coaxially fixed with the incomplete gear to rotate, when the incomplete gear 9 rotates and a toothed part of the incomplete gear is meshed with the first gear 10, the winding wheel 11 is driven to rotate, the rope 16 is tightened, the connecting rods 13 on two sides and the knocking hammers 14 fixed on the connecting rods 13 swing outwards when the rope 16 is tightened, meanwhile, the rope 16 tightens and presses the second pressure spring 26 and enables the rope to have a rebounding trend and elastic potential energy, when a toothless part of the incomplete gear 9 corresponds to the first gear 10, the knocking hammers 14 realize that the knocking hammers 14 hammer from the front side and the back side of the ice column under the gravity of the second pressure spring 26, so that the icicles and the knocking hammer 14 are damaged and fall off through the gravity of the icicles, the incomplete gear 9 continuously rotates and drives the rope 16 to repeatedly tighten and loosen through the winding wheel 11 along with the continuous forward movement of the device, and the knocking hammer 14 performs reciprocating knocking, so that the icicles are quickly knocked down.

After the back of cleaing away of accomplishing the icicle, perpendicular taut insulating stay cord 17 arranges that unmanned aerial vehicle is connected with this device, and the completion is connected with, drives this device from the inboard extrusion electric wire of pendulum rod 21 for first magnet 22 separates with second magnet 23, and the electric wire breaks away from the support from the breach this moment, and the deicing is carried out on this device installation to next group's electric wire to the unmanned aerial vehicle drive.

Compared with the traditional equipment, the device has the following advantages:

1. this device hoists through unmanned aerial vehicle, draws to rise and draws to realize fixing on the electric wire of this device with drawing through the insulation of below through the lock of U-shaped plate 1 on the electric wire during its installation, and its direct lock is on icing, and it is tight not tight with the line ball wheel clamp, has reduced installation operating procedure and installation risk, has improved the speed of deicing the post, and U-shaped plate 1 sliding resistance is littleer on icing simultaneously, and insulating stay cord 17 application of force is littleer more laborsaving.

2. Through insulating stay cord 17 as the power supply of this device, alleviateed device weight to traditional battery motor drive mode, saved time and the manpower that the repeated change battery consumed simultaneously, to ground power transmission line driven motor, stopped thereby the casualties accident that causes the electric leakage and cause by the power transmission line damage.

3. This device is still through the cooperation of spout 5 with branch 6 for this device can adapt to the icicle clearance of different width, makes first belt 3 at the more reasonable high efficiency of drive process and effectively reduce the fault rate low, strikes simultaneously from the front and back both sides of icicle in step, and is less than the stress that need overcome from breaking along electric wire length direction, has improved broken success rate.

4. The key points of the electric wire are quickly reduced by only removing the icicles, so that precious time advantage is provided for preventing the electric wire from being broken and the power tower from collapsing, after the large icicles are removed, the covered ice can be subsequently cleaned in multiple deicing modes, and the power transmission equipment is effectively protected.
