Cables are one of the indispensable transmission equipment in the power system. In cold weather, a large amount of ice or snow will gather on the overhead cables, thereby increasing the weight of the cables. Over time, it will cause the cables to break or the poles to tilt, which poses certain safety hazards. Therefore, in cold weather, it is necessary to regularly de-ice the overhead cables of the power system.

[0003] In the prior art, when de-icing the overhead cables of the power system, most operators use insulating equipment to knock on the cables, so that ice or snow on the cables fall off, thereby achieving the effect of breaking the ice.

[0036] Reference Figure 1 and Figure 2 In one aspect of the present embodiment, a wireless signal transceiver 21 and a controller 22 are installed on the top of the top plate 3 and on both sides of the second electric telescopic rod 9, respectively. The model of the wireless signal transceiver 21 is nRF24LE1, and the model of the controller 22 is S7-200. A battery 23 is installed on the top of the top plate 3 and on one side of the controller 22. The first electric telescopic rod 5, the heating wire 8, the second electric telescopic rod 9, the motor 14, the wireless signal transceiver 21 and the controller 22 are all electrically connected to the battery 23, and the battery 23 can be used to power the entire device.

The cooperation between the controller 22 and the wireless signal transceiver 21 facilitates the operator to use an external operation terminal to control the operation of the entire device.

[0037] Working principle:

[0038] When in use, the operator places the device on the cable so that the cable is located inside the groove 20 outside the fixed roller 4, and then transmits a control signal to the wireless signal transceiver 21 through the external operation terminal. After the wireless signal transceiver 21 receives the signal, it transmits the signal to the controller 22, and uses the controller 22 to control the first electric telescopic rod 5 on the top of the first L-shaped plate 2 to work, thereby driving the third L-shaped plate 24 and the rotating roller 6 inside it to move downward, and uses the cooperation between the rotating roller 6 and the fixed roller 4 to clamp the cable, and at the same time, the part of the cable located between the two heating travel components is placed in the groove 20 on the top of the matching seat 19. In addition, the control signal can be transmitted to the wireless signal transceiver 21 through the external operation terminal. After the wireless signal transceiver 21 receives the signal, it transmits the signal to the controller 22, and uses the controller 22 to control the second electric telescopic rod 9 to work, driving the second L-shaped plate 10 to move up and down, thereby adjusting the motor 14 and the cam 15 to the appropriate position;

[0039] Then the external insulating rope is passed through the through hole on the outside of the fixing plate 16 to connect it to the equipment, and then the operator on the ground can pull the equipment on the outside of the cable through the external insulating rope to perform walking operations;

[0040] While the walking operation is being performed, a control signal can be transmitted to the wireless signal transceiver 21 through an external operation terminal. After receiving the signal, the wireless signal transceiver 21 transmits the signal to the controller 22, and the controller 22 is used to control the heating wire 8 to work, thereby preliminarily heating the ice or snowflakes attached to the outside of the cable, thereby increasing the ice-breaking effect;

[0041] At the same time, a control signal can be transmitted to the wireless signal transceiver 21 through an external operation terminal. After receiving the signal, the wireless signal transceiver 21 transmits the signal to the controller 22, and the controller 22 is used to control the motor 14 to work, and the motor 14 is used to drive the cam 15 to rotate. Through the eccentric action of the cam 15, the rotation of the cam 15 and the cooperation between the matching seat 19 are used to continuously knock the cable located at the top of the matching seat 19. In the knocking process, when the cam 15 knocks on the cable located at the top of the matching seat 19, under the action force, the cam 15 and the mounting block 12 can be matched with the spring 13 in the through groove 11 to perform up and down buffering, thereby avoiding the operation of damaging the cable.

[0042] By arranging heating travel components at both ends of the equipment, when the equipment is operating on the cable, the ice or snow on the outside of the cable can be preliminarily heated, and then the cable is automatically knocked and ice-broken by the ice-breaking component arranged between the two heating travel components. The ice or snow after heating treatment is easier to break, which not only avoids the manual knocking operation and reduces the workload of the operator, but also increases the de-icing effect of the equipment, which is beneficial to practical application and operation.

[0043] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
