Electric power engineering distribution box extension structure and method

Abstract

The invention provides an electric power engineering distribution box expansion structure and method, and discloses a distribution box expansion structure and method, wherein the capacity of a distribution box can be expanded according to requirements without replacing the original box body, and inspection and maintenance of inner-layer distributors are facilitated. The distribution box expansionstructure is characterized in that a main box body and at least one auxiliary box body are horizontally arranged; the auxiliary box body is of a structure with two open ends; the main box body is connected with the auxiliary box body adjacent to the main box body through a hinge; the adjacent auxiliary box bodies are connected through hinges; a plurality of groups of locking rings are arranged onthe side surfaces, opposite to the side surfaces where the hinges are located, of the main box body and the auxiliary box body; one group of locking rings consists of two locking rings; the two locking rings in one group are arranged on two adjacent side surfaces and are close to the edges; the hinges and the locking rings are alternately arranged; an electric box door is connected with the edge of the side surface of the auxiliary box body on the outermost side through the hinges; and a groove is formed in the electric box door.

[0002] At present, in power engineering, distribution boxes are often used to sort out and protect cables and wires. However, most of the existing distribution boxes are box structures with fixed capacity. Properly increase the volume on the basis of the original distribution box to expand the volume, which is time-consuming and labor-intensive, and it is easy to cause unnecessary waste of resources

[0003] Notification number CN209626730U discloses a protective structure of a distribution box and a distribution box, including a distribution box housing, the distribution box housing includes a box body and a box door, and the left side of the box body is provided with a penetrating box body. The top of the distribution box is rotatably connected to the rotating shaft. The left side of the top of the distribution box is fixed with a protection box. The left end of the protection box is provided with a power bus that runs through the protection box. A rod, one end of the cross bar is fixed with a first fixed plate, and a second fixed plate is movably nested on the cross bar, and a spring is fixedly connected between the first fixed plate and the second fixed plate and is located on the cross bar , the lower end of the second fixing plate extends to the rear side of the power bus, and the internal space of the device is fixed. When it is necessary to add a distributor, a new device needs to be replaced, which wastes manpower and material resources
