Description

Technical Field

[0001] The utility model relates to the technical field of ice-breaking devices, in particular to an ice-breaking device for a power cable. Background Art

[0002] Under strong cold air climate conditions, ice and snow will adhere to the power line towers and lines. When the weather remains low, the lines will be covered with ice and will quickly thicken, which will increase the load weight of the lines exponentially. When the ice exceeds the line carrying capacity, the two sides of the towers will be prone to line or pole breakage due to unbalanced loads. In severe cases, it may even cause the tower to collapse. Therefore, line freezing and icing are extremely harmful to the safe and stable operation of power lines.

[0003] Therefore, it is often necessary to de-ice the power cables. In the prior art, de-icing is generally done by manual knocking. However, the distance between the two elevated towers is very long. Manual de-icing requires a person to enter the upper end of the cable and move along the cable to continuously knock and de-ice. The work efficiency is low and there is a certain degree of danger. Therefore, an improved ice-breaking device for power cables is needed to address this problem. Utility Model Content

[0008] Preferably, a counterweight is fixedly provided on one side of the surface of the second fixed frame, and the gravity of the pulley can be balanced by the counterweight to ensure the stability of the entire device during operation.

[0009] Preferably, a battery is fixedly installed at the upper end of the interior of the mounting frame, and the battery is electrically connected to the first motor and the second motor.

In this way, it can replace manual deicing by moving along the cable. Compared with manual deicing, it can improve the deicing efficiency and the processing process is safer.
