Description

Technical Field

[0001] The utility model relates to the technical field of construction site power distribution rooms, in particular to a construction site power distribution room with expandable space. Background Art

[0002] Temporary power supply projects at construction sites generally use a three-level power distribution system. To ensure power safety, the distribution cabinet and distribution box are generally isolated from the outside world by the enclosure structure. As the only bridge between the temporary power supply project and the formal power grid, the importance of the main distribution cabinet is obvious, and it requires regular operation, maintenance and repair. Therefore, the safety and reliability of the enclosure structure and the size of the internal safe operation space are particularly important for safe construction.

[0003] At present, there are mainly two types of safety protection enclosures for power distribution systems on construction sites:

[0004] The first type is to build a metal fence around the distribution box and set up a double-layer anti-smash shed on the top to completely seal the distribution box from the outside world. This type of enclosure structure is called a box protection shed. This solution is quick to build and has low site requirements.

[0005] The second type is to pour a concrete platform on the ground, then build a standardized room on the concrete platform, and place the distribution cabinet in it. This type of enclosure structure is called a distribution room, and the distribution room has good airtightness;

[0006] When the construction site is narrow, the distribution room occupies a large space, so it is often only possible to build a slender special-shaped distribution room, which leads to insufficient internal operating space and insufficient safety distance between the distribution cabinet and the wall. In this regard, construction workers generally adopt the following two solutions: one is to remove the main door of the distribution room so that the operators can directly operate the distribution cabinet outside the distribution room; the other is to adjust the position of the distribution cabinet in the distribution room, by moving the distribution cabinet, reducing the safety distance on the back of the cabinet, thereby increasing the operating space and ensuring operation safety.

[0007] However, each of the above maintenance methods has its own disadvantages:

[0008] The electrical box protection shed was once the main choice for temporary electrical safety protection at construction sites. However, due to its semi-open-air structure, wind and rain can still cause erosion to the internal power distribution system. At the same time, various small animals can enter the protection shed through the gaps in the fence, posing a huge threat to the cables. Therefore, this type of protection facility is basically no longer used on the main distribution cabinet.

[0009] Although a semi-open distribution room can ensure sufficient internal space, wild animals, such as rats and weasels, can enter the distribution room through the openings, and the indoor pipelines may be bitten, posing a huge safety risk. In addition, operators need to work outside the distribution room, with no hard protection above their heads, making them vulnerable to being hit and injured by objects. Moving the distribution cabinet in the distribution room ensures the operating space in the front, but cannot guarantee the safe distance to the sides and rear of the distribution cabinet, which also poses a safety hazard. Utility Model Content

[0010] The purpose of the utility model is to provide a construction site power distribution room with expandable space, so as to solve the technical problems such as the contradiction between insufficient internal space of the power distribution room and the excessive area occupied by the power distribution room under the condition of narrow construction site.

[0011] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0012] The utility model provides a construction site power distribution room with expandable space, comprising a fixed section and a sliding section, both of which are rectangular parallelepipeds with an opening on one side, and the openings of the fixed section and the sliding section are arranged relatively to each other; the fixed section comprises a bottom foundation, three sides of the upper surface of the bottom foundation are provided with a first side wall with mutually connected side edges, the top surface of the first side wall is provided with two layers of first top plates, and there is a gap between the two layers of first top plates; a group of horizontally arranged slide rails are provided at the middle parts of the inner side surfaces of two first side walls arranged opposite to each other in the fixed section; the sliding section comprises a bottom plate, three sides of the upper surface of the bottom plate are provided with a second side wall with mutually connected side edges; a second top plate is provided on the top surface of the second side wall, a third top plate is provided on the upper surface of the second top plate, and a first roller for rolling on the upper surface of the first top plate is provided near the end of the third top plate near the fixed section; a plurality of second rollers for sliding in the slide rails are provided at the middle parts of the outer side surfaces of two second side walls arranged opposite to each other in the sliding section, and a door for workers to enter and exit is provided on the second side wall of the sliding section facing the fixed section.

[0013] Preferably, the fixed section is further provided with first support rods, which are arranged at intervals on the edges of the two layers of the first top plates to support the two layers of the first top plates.
