Problems solved by technology

[0002] Freezing rain and snow accumulation in winter often lead to ice accumulation on transmission cables. If the ice accumulation is not removed for a long time, it will seriously threaten the safe operation of the power grid. The accidents caused by cable ice accumulation have caused huge economic losses to the country.
Damage to hardware, brittle cables, and even tilting or collapse of towers caused by severe ice accumulation often lead to large-scale power outages and affect people's normal production and life
[0003] At present, there are two main ways of deicing: one is artificial deicing, that is, sending electric workers to beat the ice accumulation with wooden sticks, which is inefficient, has great limitations, and is very dangerous; the other is short-circuit ice melting, that is, Let the circuit be short-circuited instantly to generate heat and deicing, but this method will inevitably lead to power interruption, and the energy consumption is huge, but the effect is not ideal
Judging from the prior art, there is no efficient and practical deicing machine for high-voltage transmission lines

Embodiment

[0027] Examples of the present invention Figure 1-6 As shown, it consists of a host 1, a beating device, and a walking device. It is characterized in that the host 1 includes a microprocessor 17, a power supply 18, a wireless receiving module 19, an ice accumulation detector, a limit switch 21, a motor drive module 20, and an alarm. The detector module 22 and the lighting device 12; the wireless receiving module 19, the limit switch 21, the motor drive module 20, the alarm module 22 and the lighting device 12 are respectively connected with the microprocessor through the I / O port; The probe 16 is connected to the limit switch 21. The L-shaped probe 16 is installed in the middle of the front end of the shell of the host 1. When the L-shaped probe 16 touches the ice accumulation, it is pushed back to generate displacement and push the limit The action of the switch 21 generates a level conversion signal; the power supply 18 is connected to the microprocessor 17, the wireless re...
