Waterproof and dustproof distribution box for building construction site

Abstract

A waterproof and dustproof power distribution box for a building construction site is a special secondary power distribution box, comprises a power distribution box body and a box cover, and is characterized in that the power distribution box body is a cuboid with the length of 630 mm, the width of 260 mm and the height of 750 mm; a box door opened through a rotating shaft is arranged on the frontsurface of the distribution box; the box door is marked with a distribution box name and provided with a door lock; the two side faces of the distribution box correspond to each other; a handle is arranged between the side faces and used for moving the distribution box; a ventilation shutter is arranged on the handle; four sockets are arranged on the lower portion of the handle; and the box coveris a rectangular iron plate and covers the top end of the box body of the distribution box. The waterproof and dustproof power distribution box for the building construction site has the advantages that the power distribution box device is simple in structure and convenient to manufacture; the problem that circuits are disorderly connected on the construction site is avoided; tripping and electric shock accidents are avoided; the waterproof and dustproof effects are achieved; the protection grade is high; the power distribution box is suitable for outdoor use; electric shock accidents are reduced; and construction power consumption management is facilitated.

Description

technical field [0001] The invention relates to a distribution box, in particular to a waterproof and dustproof distribution box for building construction sites. Background technique [0002] There are strict electrical regulations for the safety of electricity use on construction sites. All electricity used in the construction site needs to implement "three-level power distribution, two-level protection" and "TN-S three-phase five-wire power supply system", as well as "one machine" and "one box". "" "one gate" and "one leak" four installation principles. Usually, the construction main distribution box is used as the first-level power distribution, and the distribution box is used as the second-level power distribution; the equipment control box is used as the third-level power distribution box, and the plug connection is used from the third-level distribution box to the second-level distribution box. Inside the electrical box, the secondary distribution box at the construc...

AI Technical Summary

Problems solved by technology

Some operators with weak awareness of labor safety often do not cooperate with the management, privately modify the wiring seriously, or the distribution box facilities are not complete, which is likely to cause safety accidents such as electric shock

[0003] Therefore there is above-mentioned inconvenience and problem in known distribution box facility
