Description

Technical Field

[0001] This utility model relates to the field of power distribution rooms, specifically to a prefabricated panel-assembled power distribution room. Background Technology

[0002] In the current wave of the digital economy, the demand for computing power from applications such as AI training, cloud computing, and the industrial internet is experiencing explosive growth. As the core "computing infrastructure," the construction speed of data centers directly determines whether enterprises can quickly seize market opportunities and maintain competitiveness. Therefore, shortening the construction cycle of data centers from planning to commissioning has become a key measure for the industry in terms of resource allocation and cost control. The traditional civil engineering-based data center construction model involves complex civil construction, on-site decoration, and equipment installation, with a cycle typically exceeding one year. This not only means huge investments in land, building materials, and manpower, but also carries the risks of "high costs" and "delayed returns" due to the long construction period.

[0003] To address this challenge, "prefabrication" has become a clear development direction for the industry. Containerized power modules, which integrate key support systems such as power distribution and HVAC, are one of the core solutions for rapid deployment. They employ a factory prefabrication and on-site hoisting construction model, which theoretically can significantly shorten the construction period. However, existing containerized power modules still face a key bottleneck in practice: their containers often need to be customized to various non-standard sizes according to the internal equipment layout, making mass production using globally mature and efficient standard container automated production lines impossible. This reliance on "tailor-made" production inevitably introduces a large number of manual welding and correction processes, which not only increases costs and makes it difficult to guarantee the first-pass yield of welds, but also severely restricts the production efficiency and delivery speed of the containers, preventing the cost and time advantages of this type of product from being fully realized in the domestic market.

[0004] Therefore, a structural solution with certain universality is needed to solve the above problems.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this utility model, and therefore may include information that does not constitute prior art known to those skilled in the art.

The door panels are installed on the front prefabricated side panels through door panel opening frames. This utility model solves the problem of high cost for non-standard containers, improves standardization, and significantly reduces manufacturing costs and construction time.

[0025] The prefabricated panel-assembled power distribution room in this example embodiment will be further described below.

[0026] like Figures 1-6 As shown, the prefabricated modular power distribution room includes a container frame 100, prefabricated panels 200, power distribution equipment, building equipment, and door panels 500, wherein: The container frame 100 is a container frame assembled from a container base frame 110, a container top frame 120, and multiple container vertical beams 130 connected by corner fittings 140. The sides of the container frame 100 have prefabricated side panel mounting frames composed of the container base frame 110, the container top frame 120, and multiple container vertical beams 130, and the top surface of the container frame 100 has a prefabricated top panel mounting frame composed of the container top frame 120.

[0027] The precast slab 200 includes a precast side slab embedded in the precast side slab mounting frame and a precast top slab embedded in the precast top slab mounting frame. The precast side slab includes a front precast side slab, left and right precast side slabs, and a rear precast side slab.

[0028] The power distribution equipment includes a transformer 310, an incoming line cabinet 320, a distribution cabinet 330, and a UPS cabinet 340. The heavy power distribution equipment (transformers, distribution cabinets, etc.) is centrally arranged at the rear of the cabin through a power module base and is fixed by a rigid connection with the container base frame 110, ensuring structural stability.

[0029] The power module base and the rear prefabricated side panel are spaced approximately 600mm apart to form a dedicated maintenance space. This layout greatly facilitates wiring, inspection and maintenance operations on the equipment from the front, forming a clear and efficient "operation-maintenance" flow, and improving the safety and convenience of operation and maintenance.

[0030] The building equipment is installed on the precast slab through pre-set openings or fixing structures. The door panel 500 is installed on the front precast side panel through a pre-set door panel opening frame on the precast side panel.

[0031] In the embodiments of this example, as Figures 1-7 As shown, the container base frame 110 is made of T-shaped steel, the container top frame 120 is made of Z-shaped steel, and the container vertical beams 130 are made of U-shaped steel. The prefabricated side panel installation frame is formed by the ground-perpendicular sides of the container base frame 110, the ground-perpendicular sides of the container top frame 120, and the left and right sides of multiple container vertical beams 130. This frame layout, composed of T-shaped, Z-shaped, and U-shaped steel, not only provides clear stress distribution and structural stability but also ensures the accuracy and efficiency of prefabricated panel installation through its regular interface, structurally guaranteeing the precise realization of the overall layout.

[0032] In the embodiments of this example, as Figures 1-7As shown, the container roof frame 120 also includes support beams with multiple U-shaped structural steel members. The prefabricated roof installation frame is formed by the bottom edge of the container roof frame 120 parallel to the ground and the left and right sides of the multiple support beams. By adding support beams, a stable and load-bearing gridded roof installation interface is formed. This layout ensures the flatness and reliability of the roof installation, providing a solid foundation for the safe and reasonable installation of building equipment such as lighting on the roof, and avoiding the impact on the internal space due to roof deformation.

[0033] In the embodiments of this example, as Figures 6-7 As shown, the container base frame 110, container top frame 120, and container vertical beams 130 are all provided with screw holes for connection to the prefabricated panels 200 with corresponding holes via screws 630. This achieves a standardized and modular connection layout between the container frame 100 and the prefabricated panels 200. It eliminates errors from on-site measurements, greatly improves assembly efficiency, and ensures the accuracy and sealing of the entire cabin enclosure structure layout.

[0034] In the embodiments of this example, as Figures 1-5 As shown, the building equipment includes a gas extinguishing device 410, lighting equipment 420, monitoring equipment 430, and ventilation equipment. The ventilation equipment includes a ventilation window 441 and a wall-mounted air conditioning unit 442.

[0035] The front prefabricated side panel is pre-installed with gas extinguishing device 410 mounting clips. The front prefabricated side panel is pre-installed with air conditioning opening frames for mounting wall-mounted air conditioning unit 422. The front prefabricated side panel is pre-installed with monitoring device 430 mounting clips. The left and right prefabricated side panels are pre-installed with ventilation window opening frames for mounting ventilation windows 441. The prefabricated top panel is pre-installed with lighting device 420 mounting clips. By placing the wall-mounted air conditioning unit 442, ventilation windows 441, and other environmental equipment on the front and side panels, effective airflow organization is achieved; gas extinguishing and monitoring are concentrated at the front, covering the main equipment area and entrance. This layout clearly defines the functions of each system, optimizes installation location, and maximizes space utilization and system efficiency.

[0036] In the embodiments of this example, as Figures 1-5As shown, the gas extinguishing device 410 is directly installed on the inner surface of the front precast side panel via gas extinguishing fixing clips. The monitoring device 430 is fixedly installed on the monitoring fixing clips on the inner surface of the front precast side panel via a mounting base. The lighting device 420 is fixedly installed in the lighting fixing clips on the inner surface of the precast top panel via a mounting base. The wall-mounted air conditioning unit 442 is assembled in the air conditioning opening frame opened on the front precast side panel. The ventilation window 441 is assembled in the ventilation window opening frames opened on the left and right precast side panels. By integrating the mounting clips and openings at specific locations on the precast panels during the factory prefabrication stage, "aligned installation" is achieved after the equipment arrives on site. This layout method avoids damage to structural integrity and thermal insulation caused by on-site openings, protects the performance of the precast panels, and ensures that all equipment can be positioned according to the optimal plan, resulting in high installation quality and a unified and standardized layout.

[0037] In the embodiments of this example, as Figures 7-8 As shown, the system also includes a sealing assembly. This sealing assembly is disposed on the contact surface between the precast slab and the corresponding precast side panel mounting frame and precast top panel mounting frame, for achieving a sealed connection between the precast slab and the container frame. The sealing assembly includes a first sealing strip 610 and a second sealing strip 620. The first sealing strip 610 is a P-type sealing strip, which is adhered to the inner contact surface of the precast side panel mounting frame and the precast top panel mounting frame. The edge of the precast slab is pressed against the head of the P-type sealing strip by screws 630, causing it to deform and thus achieving a seal. The second sealing strip 620 is disposed on the contact surface between the door opening frame of the front precast side panel and the door panel. The second sealing strip 620 is adhered to the door opening frame, and its displacement is limited by a sealing strip fastener installed on the inner side of the door opening frame. This reliable sealing ensures a complete and controlled internal environment within the container compartment. It effectively isolates external moisture and dust, ensuring the safe operation of precision electrical equipment, while also maintaining the effectiveness of cabin thermal management.

[0038] In the embodiments of this example, as Figures 6-7 As shown, after the prefabricated side panels and prefabricated top panels are embedded from the outside of the container body into the corresponding prefabricated side panel mounting frames and prefabricated top panel mounting frames, the screws 630 are passed through the container frame 100 and the tail of the first sealing strip 610 from the inside of the container body and fixed into the corresponding screw holes on the prefabricated panels 200 for auxiliary fixing. This sequence first completes the initial positioning and sealing alignment of the panels from the outside, and then performs the final tightening from the inside, ensuring that the sealing strip can be evenly compressed to achieve the best sealing effect.

[0039] In this example embodiment, the precast panel 200 is a sandwich panel structure, including a fireproof and heat-insulating core layer at the core and a steel plate surface layer surrounding the fireproof and heat-insulating core layer. Preferably, the fireproof and heat-insulating core layer can be made of rock wool. This effectively reduces the impact of the external environment on the internal temperature, providing a stable operating environment for the power distribution equipment, and also improves the fire safety level of the cabin.

In fact, according to the embodiments of this utility model, the features and functions of two or more modules or units described above can be embodied in one module or unit.
