Description

Technical Field

[0001] The invention relates to the technical field of power distribution rooms, and in particular to a flat-lay prefabricated power distribution room. Background Art

[0002] A distribution room refers to an indoor distribution site with a low-voltage load, which mainly distributes electricity to low-voltage users. It is equipped with medium-voltage incoming lines, distribution transformers and low-voltage distribution devices. In modern society, people's lives and work are inseparable from electricity, and higher requirements are placed on the safety and stability of the power grid. As an important part of the power grid, the rationality of the design of the distribution room has a significant impact on the improvement of power supply quality. In recent years, the distribution room industry has developed rapidly and has become an important part of the power industry. With the country's emphasis on power safety and the promotion of the development of new energy, the distribution room industry market has shown good development potential.

[0003] In the existing technology, most distribution rooms are brick-concrete structures, which have the disadvantages of long construction period and large floor space, affecting residents' lives. The electrical construction environment cannot be guaranteed, which is prone to electrical failures due to wind and dust. Modular construction cannot be achieved and the large volume occupies too much land resources after completion. The installation of photovoltaic panels may damage the roof waterproof structure and cause water leakage. Higher-power HVAC equipment is required, which consumes more electricity and is not energy-saving and environmentally friendly. There is no friendly design for thermal insulation, etc. Summary of the invention

[0004] Based on this, the purpose of the present invention is to provide a flat-lay prefabricated distribution room to solve the technical problems in the prior art that most distribution rooms are brick-concrete structures, have long construction periods, occupy large areas and affect residents' lives.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solutions: a flat-laying prefabricated power distribution room, comprising a base frame, wherein the four corners of the top of the base frame are respectively provided with a first side wall panel and a second side wall panel facing each other; Both sides of the inner walls of the two groups of the first side wall panels are rotatably connected with first connecting plates, and the first connecting plates and the first side wall panels are rotatably connected via a first rotating shaft, and a storage groove matching the first connecting plates is provided inside the first side wall panels, and a protruding extrusion block is fixed on the inner side of the first connecting plates, and both ends of the inner walls of the two groups of the second side wall panels are rotatably connected with second connecting plates, and the second connecting plates and the second side wall panels are rotatably connected via a second rotating shaft, and a pressure plate matching the protruding extrusion block is obliquely fixed on one side of the second connecting plates; The base frame is composed of a mounting frame, two groups of first folding blocks, two groups of second folding blocks and a folding shaft. The two groups of the first folding blocks, the two groups of the second folding blocks and the mounting frame are rotatably connected through the folding shaft, and the two groups of the first folding blocks and the second folding blocks are fixedly connected to the first side wall panel and the second side wall panel respectively. The first connecting plate and the second connecting plate are both provided with corresponding locking holes, and the inner walls of the locking holes are provided with internal threads; A ceiling plate is arranged on the top of the four groups of the second connection plates, and corresponding connection holes and matching holes are respectively opened at the four corners of the four groups of the second connection plates and the ceiling plate, and the connection holes and the matching holes are fastened and connected by bolts; The bottom frame also includes a plug-in board and a bottom board, wherein the plug-in board is fixed on the top of the first folding block and the second folding block, and the top of the plug-in board extends to the inside of the first side wall board and the second side wall board, and the bottom board is fixed to the bottom end of the inside of the mounting frame; The two groups of the first side wall panels and the two groups of the second side wall panels are provided with matching roof modules on the top, and the interior of the base plate and the roof module are filled with rock wool and polyurethane foaming agent. The first side wall panels and the second side wall panels are both composed of an outer insulation skin layer, a column frame and an inner rock wool insulation layer, and the interior of the outer insulation skin layer is filled with polyurethane foaming agent.

[0006] By adopting the above technical solution, the power distribution room is assembled mutually through folding modularization. First, the two groups of first folding blocks are flipped to a vertical state, and then the bottoms of the two groups of first side wall panels are plugged into the plug-in boards of the two groups of first folding blocks. At this time, the first connecting plate on the first side wall panel is manually opened, and the two groups of second side wall panels are connected to the two groups of second folding blocks. Then, the second side wall panel is manually unfolded. When the second side wall panel is rotated to a vertical state, the first connecting plate squeezes and pushes the second connecting plate of the second side wall panel. That is to say, at this time, the protruding extrusion block of the first connecting plate squeezes the pressure plate of the second connecting plate to a certain extent, so that the second connecting plate is rotated to a horizontal state, and then the four groups of second connecting plates in a horizontal state are easy to be connected and fixed to the ceiling panels. From the above, it can be seen that not only the foldable modular assembly molding is adopted to effectively reduce the problems of long construction period and large construction area affecting the lives of residents, but also after unfolding, the two groups of first side wall panels, the two groups of second side wall panels and the ceiling panels are connected and coordinated with each other, so that the overall stability after assembly is better, thereby improving the overall service life of the distribution room.

[0007] Furthermore, a plurality of fresh air system on-off valves are provided inside the ceiling panel, a plurality of fresh air fans located above the ceiling panel are provided at the top of one group of the first side wall panels, and a fresh air system air inlet is provided at a corner of the bottom of one group of the second side wall panels; An air duct extending downward is arranged at the middle position of the top of the ceiling panel, and an air conditioner indoor unit located inside the air duct is fixed to the top of the inner wall of one group of the first side wall panels; A transformer room, an integrated power distribution room and an air-conditioning outdoor unit equipment room are respectively arranged on the top of the base frame, wherein a group of the second side wall panels are provided with a transformer air inlet corresponding to the transformer room, and a group of the second side wall panels are provided with an air-conditioning outdoor unit air outlet corresponding to the air-conditioning outdoor unit equipment room.

[0008] By adopting the above technical solution, the fresh air system adopts natural air intake, wherein the air inlet of the fresh air system adopts an electric shutter structure, and the fresh air fan adopts a fan valve structure, which plays a role of active exhaust for the distribution room. The air-conditioning system and the fresh air system are turned on and off through the internal environmental control strategy. When the air-conditioning system needs to be started, the fresh air system is turned off to keep the air inside and outside the distribution room from circulating and reduce heat loss. When the fresh air system needs to be turned on, the air-conditioning system is in a closed state.

[0009] Furthermore, a solar panel is arranged on the top of the roof module, and a connecting groove engaged with the first side wall panel and the second side wall panel is opened at the bottom of the roof module, and fastening angle panels matching the first side wall panel and the second side wall panel are fixed at the four corners of the bottom of the roof module.

[0010] By adopting the above technical solution, the connecting groove further improves the top structure, provides better waterproofing, thermal insulation and other properties, and the connecting groove and the fastening corner plate make the connection between the roof module and the wall panel more stable.

[0011] Furthermore, a partition located on one side of the transformer room is fixed on the top of the base frame, and the partition, two sets of first side wall panels, the integrated power distribution room and the air-conditioning outdoor equipment room are all provided with closed doors.

[0012] By adopting the above technical solution, the relative independence of each partition is achieved through closed doors, which is convenient for equipment maintenance and management. The transformer room, air-conditioning outdoor equipment room, integrated distribution room and maintenance passage are separate door rooms with good independence, which can effectively prevent unauthorized personnel from entering.

[0013] In summary, the present invention mainly has the following beneficial effects: 1. The power distribution room of the present invention is assembled with each other through folding modularization. First, the two groups of first folding blocks are flipped to a vertical state, and then the bottoms of the two groups of first side wall panels are plugged with the plug-in boards of the two groups of first folding blocks. At this time, the first connecting plate on the first side wall panel is manually opened, and the two groups of second side wall panels are connected to the two groups of second folding blocks. Then, the second side wall panel is manually unfolded. When the second side wall panel is rotated to a vertical state, the first connecting plate squeezes and pushes the second connecting plate of the second side wall panel. That is to say, the protruding squeezing block of the first connecting plate squeezes the pressure plate of the second connecting plate to a certain extent, thereby rotating the second connecting plate to a horizontal state, and then the four groups of second connecting plates in a horizontal state are convenient to be connected and fixed with the ceiling panel. As can be seen from the above, not only the folding modular assembly molding is adopted, which effectively reduces the problems of long construction period and large construction area affecting residents' lives, but also after unfolding, the two groups of first side wall panels, the two groups of second side wall panels and the ceiling panel are connected and coordinated with each other, so that the overall stability after assembly is better, and the overall service life of the power distribution room is improved; 2. The base frame, the first side wall panel, the second side wall panel, the roof module and other components of the present invention adopt effective thermal insulation measures. The base frame and the roof module are filled with polyurethane foam and rock wool. The first side wall panel and the second side wall panel include an outer insulation skin layer, a column frame, and an inner rock wool board insulation layer to form a "sandwich" insulation structure, wherein the interior of the outer insulation skin layer is filled with polyurethane foam, which can effectively isolate the heat conduction inside and outside the distribution room and reduce heat exchange, thereby improving the thermal insulation performance of the distribution room and reducing energy consumption.
