The beneficial effects of the utility model:

1. The utility model can be used as an automatic deicing tool for overhead high-voltage cables, avoiding the danger caused by manual deicing, and at the same time improving the deicing efficiency. The device has a simple structure and a good deicing effect.

2. In the utility model, the heavy hammer is connected to the swing rod through the leaf spring, and the leaf spring can absorb the vibration caused by the heavy hammer hitting the ice, thereby protecting the body of the cable deicing mechanism. At the same time, the heavy hammer can increase the impact force of the heavy hammer on the ice through the energy storage and energy release of the leaf spring.

3. In the utility model, the roller II presses the deiced cable on the driving shaft with V-shaped groove through the action of the spring, and drives the cable and the deicing mechanism through the friction force between the cable and the V-shaped groove. The relative movement enables continuous de-icing of the cable. At the same time, the roller II presses the deiced cable on the passive wheel with V-shaped groove through the action of the spring, which plays the role of righting the cable or the deicing mechanism.
