Description

Technical Field

[0001] The utility model relates to the technical field of construction protection, and in particular to a safety protection device for power transmission and transformation engineering construction. Background Art

[0002] The power transmission and transformation project is responsible for the construction of transmission lines of various voltage levels, substation installation projects, cable and optical cable laying projects, and various types of microwave tower construction projects. In order to prevent irrelevant personnel from entering and to allow personnel entering the work area to take good protection, it is necessary to install protective devices at the entrance of the work area as a warning and reminder. Power transmission and transformation project construction safety protection devices are required.

The utility model improves the stability of the guardrail through multiple guardrails that can be quickly connected and disassembled, making the guardrail less likely to collapse.
