[0002] The main function of the distribution box protection shed is isolation, that is, to isolate the distribution box from people and animals to prevent people and animals from getting close to the distribution cabinet and causing electric shock. At present, the distribution box protection sheds commonly used on construction sites are mostly built with steel pipe frames as the main components, and the steel pipe frames or other components are fixed by welding. This method has many inconveniences: first, it is not easy to carry after welding; second, it is not easy to disassemble. Disassembly requires cutting operations, which not only wastes human resources, but also causes material waste.

[0003] The patent document with application number 202123242038.4 discloses a detachable distribution box protection shed, which includes multiple guardrails, and a warning plate is arranged on the upper part of the guardrails. The guardrails are assembled to form a fence and a top cover is installed on the upper part of the fence to complete the assembly. Although the protective device changes the welding of the guardrails to bolt connection, the guardrails on each side are still a whole, which still requires a large space for handling and transportation, and the guardrails are too high, making it difficult to assemble the top, and the assembly convenience is relatively poor.
