step one (hoisting step of the deicing device), hoisting the deicing device of the power transmission line 4 to one side of the power transmission line 4 by using a crane, hooking an upper horizontal rod 7 in the hoisting process, then opening a pull buckle 3 between an upper front side plate 1 and a lower front side plate 2, enabling the lower front side plate 2 and a lower rear side plate 6 to rotate downwards around the hinged part of the upper rear side plate 5 and the lower rear side plate 6, then enabling a driving travelling wheel 10 and a driven travelling wheel 8 to be lapped on the power transmission line 4, and then buckling the pull buckle 3 again;
step two (operation and control operation step of the deicing device), the driving motor 42, the knocking motor 47 and the cutting motor 40 are started at the same time, the walking mechanism drives the deicing device to move on the transmission line 4 at a set speed at a constant speed, in the process that the deicing device moves on the transmission line 4, the upper cutting wheel 13 and the lower cutting wheel 14 are both positioned at the front end of the deicing device, two ice seams are cut at the bottom and the top of an ice coating 44 on the transmission line 4 firstly, then the knocking block 28 strikes the cut ice coating 44, and the ice coating 44 is broken and falls off from the transmission line 4;
and step three (a detaching step of the deicing device), after the deicing device moves to the tail end of the power transmission line 4, the deicing device is upwards pulled by a crane, so that the driving travelling wheels 10 and the driven travelling wheels 8 are separated from the power transmission line 4, then the pull buckle 3 between the upper front side plate 1 and the lower front side plate 2 is opened, the lower front side plate 2 and the lower rear side plate 6 are downwards rotated around the hinged part of the upper rear side plate 5 and the lower rear side plate 6, then the deicing device is removed from the power transmission line 4, and then the pull buckle 3 is buckled again.
Compared with the traditional manual deicing mode, the invention realizes the mechanical operation of deicing of the transmission line 4, not only reduces the labor intensity of workers, but also greatly improves the deicing efficiency. Compared with the existing deicing device, the driving mechanism 19 of the invention can ensure that enough knocking force is provided between the knocking block 28 and the power transmission line 4, and the knocking force can be kept stable and not attenuated even after the device is used for a long time. In addition, the whole structure of the invention is reasonable in layout, and the uniform distribution of the whole weight of the device can be realized only by adding a small balancing weight or even not adding the balancing weight, thereby preventing the device from inclining on the power transmission line 4.
