In this embodiment, the number of insulators 3 and insulating wire clamps is four respectively, and of course, it can also be designed to be two, six or eight according to usage needs.

[0020] The insulating wire clamp includes a U-shaped insulating card 41, an insulating pressure plate 42 and an insulating screw 44. A through hole is opened at one end of the insulating pressure plate 42, and a circular hole is opened at the other end. An arc-shaped insulating pressure block 43 is fixedly installed on one side of the insulating pressure plate 42 corresponding to the inner cavity of the U-shaped insulating card 41. The long side wall of the U-shaped insulating card 41 passes through the through hole, and the short side wall is installed with an insulating nut 45. The insulating screw 44 passes through the circular hole and is threadedly connected with the insulating nut 45. By rotating the insulating screw 44 forward, the insulating pressure plate 42 is moved closer to the high-voltage line, and then the high-voltage line is limited in the U-shaped insulating card 41.

[0021] The interior of the insulating shell 1 is hollow, and four guide sleeves 26 are mounted around the side wall thereof. Insulating rods 25 are arranged in the guide sleeves 26 , and the insulating rods 25 can slide in the guide sleeves 26 .

[0022] The four insulators 3 are respectively arranged corresponding to the four insulating rods 25 , and one end of the insulator 3 is fixedly connected to the insulating rod 25 , so that the insulating rod 25 can drive the insulator 3 to move.

[0023] The power unit includes a driving assembly, four crankshafts 21 and four pull rods 23. The four crankshafts 21 are arranged in an insulating shell 1 and correspond to four insulating rods 25 respectively. The front and rear ends of the crankshaft 21 are respectively provided with bearings 2, and the two bearings 2 are respectively installed on the front side wall and the rear side wall of the insulating shell 1. The crankshaft 21 is provided with a bearing 1 22.

[0024] One end of the pull rod 23 is fixedly connected to the outer ring of the bearing 22, and the other end is hinged to the hinge seat 24 through a pin shaft. The hinge seat 24 is fixedly connected to the inner end of the insulating rod 25. During the rotation of the crankshaft 21, the pull rod 23 pulls the hinge seat 24, the insulating rod 25, the insulator 3 and the insulating wire clamp to reciprocate. The mechanized reciprocating motion can more effectively destroy the adhesion between the ice layer and the high-voltage line, and quickly achieve the purpose of vibration de-icing.

[0025] The driving assembly includes a driving motor 62 and four synchronous wheels 61. The four synchronous wheels 61 are respectively mounted on the four crankshafts 21.

[0026] An outer shield 9 is provided on the outer side of the driving motor 62 to protect the driving motor 62 . The outer shield 9 is fixedly mounted on the front side of the insulating shell 1 .

[0027] When used specifically, the present invention is a vibration de-icing device for ultra-high voltage lines. First, four insulating wire clamps are connected to four high-voltage wires respectively, then the drive motor 62 is energized and the operation of the drive motor 62 is controlled. The four crankshafts 21 are driven to rotate synchronously through the transmission action of the synchronous belt 63 and the four synchronous wheels 61. During the rotation, the crankshaft 21 pulls the articulated seat 24, the insulating rod 25, the insulator 3 and the insulating wire clamp to reciprocate through the pull rod 23. The reciprocating motion of the insulating wire clamp causes the high-voltage wire to shake, thereby achieving the purpose of vibrating and de-icing the four high-voltage wires at the same time.

By controlling the operation of the driving motor 62, the four crankshafts 21 are driven to rotate synchronously through the transmission action of the chain and the four sprockets.

[0030] Embodiment 4: Based on the first embodiment, the differences are as follows: Figure 1 and Figure 3 As shown, it also includes a battery 5, a receiver 7, a controller 8 and a remote controller (not shown in the figure). The battery 5 is fixedly mounted on the inner side of the insulating shell 1, and the receiver 7 and the controller 8 are respectively mounted in the outer shield 9. The battery 5 is electrically connected to the controller 8 and the drive motor 62 respectively. The remote controller communicates with the receiver 7 through wireless signals and outputs signals to the controller 8 through the receiver 7. The controller 8 is used to control the operation of the drive motor 62, so that the drive motor 62 can be started using the remote controller, which reduces the need for manual direct contact with the high-voltage line and can be operated at low altitude under severe weather conditions, thereby improving the convenience and safety of the operation.
