Description

Technical Field

[0001] This invention relates to the field of power supply operation and maintenance protection equipment technology, and in particular to a high-voltage live-line working shielding equipment. Background Technology

[0002] As is well known, power supply maintenance involves extremely high risks during live-line work at high voltage. Due to unpredictable factors in the working environment, injuries to maintenance personnel are frequent, especially to the feet. The impact force generated by power equipment can knock objects to the ground, causing foot injuries to workers. Although workers now wear heavy protective boots to mitigate this problem, these boots are difficult to put on due to their thickness and weight, sometimes requiring assistance, which is time-consuming and laborious. This is especially true in hot weather, as the heavy boots make it difficult for workers to dissipate heat, greatly increasing the risk of heatstroke. Sweat also accumulates on the workers' bodies, further aggravating their discomfort. Therefore, we propose a shielding device for live-line work at high voltage. Summary of the Invention

[0021] In the high-voltage live-line working shielding equipment described in Example 1, the limiting devices below the two shoe covers 2 are first pulled down to separate the shoe covers 2 from the limiting devices.

During work, when the worker is constantly moving on the field, the fan blades 15 in the connecting box 5 swing up and down as the worker moves, blowing the cool air generated by the external movement toward the wrapped legs. The airflow causes the sweat on the legs to evaporate and remove a lot of heat, which can not only make the worker feel cool, but also increase the worker's comfort.
