Description

Technical Field

[0001] The utility model belongs to the technical field of distribution boxes, and in particular relates to a distribution box for building construction. Background Art

[0002] Building construction refers to the production activities in the implementation stage of engineering construction. It is the construction process of various buildings. It can also be said to be the process of turning various lines on the design drawings into physical objects at designated locations. It includes foundation engineering construction, main structure construction, roof engineering construction, decoration engineering construction, etc.

[0003] The distribution box is a low-voltage power distribution device that assembles switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen according to the requirements of electrical wiring. In normal operation, the circuit can be connected or disconnected with the help of manual or automatic switches. In case of failure or abnormal operation, the circuit can be cut off or an alarm can be given with the help of protective electrical appliances. The measuring instruments can display various parameters in operation, and some electrical parameters can also be adjusted, and prompts or signals can be issued for deviations from normal working conditions. It is often used in various power generation, distribution and substations.

[0004] A distribution box for construction is a distribution box that is installed inside or outside a construction site and is temporarily used to provide power supply and related power control during the construction process.

[0005] The authorization publication number "CN115579762A" records "a distribution box for use at a construction site. It includes a distribution box body and a falling object buffering mechanism arranged on the top of the distribution box body, the falling object buffering mechanism at least includes: a shielding device, the shielding device includes a fixed plate, the outer walls of the four sides of the fixed plate are provided with rotation grooves, the rotating grooves are provided inside the fixed cylinders, the outer walls of the fixed cylinders are provided with connecting frames, a winding rod is rotatably provided inside the fixed cylinder, one end of a shielding cloth is fixedly provided on the outer wall of the winding rod, the other end of the shielding cloth extends out of the fixed cylinder, the end of the shielding cloth is connected to a limiting block, an adjustment device is provided between the limiting block and the connecting frame, an elastic shielding shed, the elastic shielding shed includes an airbag, the airbag is fixedly provided on the top of the fixed plate, the outer wall of the airbag is connected to an air intake pipe, and the end of the air intake pipe is threadedly connected with a sealing cover. The present invention can effectively buffer the damage to the distribution box caused by foreign objects falling at the construction site, and can shield the periphery of the distribution box."

[0006] The above patent sets a shielding device, and the shielding cloth extends out of the fixed cylinder to shield the surface of the distribution box body. When foreign objects fall from the top, the foreign objects fall to the top of the shielding cloth.
