Problems solved by technology
However, the current laser deicing technology device requires human operation and control throughout the entire process. The deicing operation is controlled by humans to observe the icing situation. The real-time feedback is poor and the work efficiency is low. In the case of poor light conditions, the deicing effect is poor. certain danger

Embodiment Construction
[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0022] Infrared rays are electromagnetic waves with wavelengths between microwaves and visible light. They are invisible to the human eye. Almost all objects in nature can emit infrared rays. The core of the thermal imager is a sensor that can detect extremely small temperature differences, and convert the temperature differences into real-time video images for display. Any object with temperature will emit infrared rays. The thermal imager receives the infrared rays emitted by the object, displays the temperature distribution on the surface of the measured object through colored pictures, and finds out the abnormal points of temperature according to the small difference in temperature. When the deicing device works in a dark environment with no visible light or low light, the visible light camera cannot work. At this time, the infrared thermal imager c...

Description
technical field [0001] The invention relates to the field of deicing of high-voltage transmission lines in power systems, in particular to an infrared-based laser deicing device. Background technique [0002] In severe cold, rainy and snowy weather in winter, transmission lines and towers are likely to be covered with ice and snow. In severe cases, it may cause cable breakage and tower collapse, resulting in casualties of people and animals around, damage to transmission lines, and great losses. Overhead transmission lines have the characteristics of multiple points, wide areas, large spans, and long lines. Deicing of transmission lines is very difficult. [0003] Existing methods for removing ice and snow from high-voltage transmission lines mainly include four types: mechanical deicing, thermal ice melting, natural deicing (also called passive deicing), and mixed methods. Mechanical deicing is a kind of contact deicing operation, which has poor safety performance, require...
