Description

technical field

The present invention relates to the technical field of electrical works, more particularly to a protective device for electrical works.

State of the art

Nowadays, the number of electrical construction sites in society is constantly increasing. During electrical work, in order to prevent pedestrians from accidentally entering a construction area, it is necessary to erect protective fences outside the construction area, which not only ensure the safety of pedestrians, but also do not affect the construction work of the construction workers.

For convenience of setting up and taking down, some safety fences are placed directly on the ground, with no connection between safety fences. Therefore, the protective fences have poor stability and are easily pushed down by external forces, which poses certain security risks.
