Description

Technical Field

[0001] This utility model relates to the field of prefabricated modular data center technology, specifically a prefabricated modular data center roof joint sealing node and data center. Background Technology

[0002] Prefabricated modular data centers are pre-engineered solutions where information technology equipment (such as servers, switches, firewalls, etc.), along with supporting power supply, cooling, fire protection, and monitoring equipment, are integrated into modular enclosures in a factory according to project requirements. These enclosures are then transported to the project site for assembly and stacking before being put into use. Due to their short construction cycle, high flexibility, and stable construction quality, they are gradually becoming the mainstream trend in data center construction.

[0003] Waterproofing and insulation in roof construction are among the most important factors affecting the functionality of a building, and also a weak point. Data centers house a large number of high-value, precision devices that are sensitive to the environment and expensive. Therefore, waterproofing and insulation are particularly important for prefabricated modular data center projects. If waterproofing fails or insulation is inadequate, it can lead to equipment damage or increased energy consumption, with very serious losses and consequences.

[0004] Prefabricated modular data centers are constructed by assembling and stacking different modular shipping containers. The sealing effect of the roof joints directly determines the roof's waterproofing and insulation performance. Existing roof joint sealing solutions use different materials for waterproofing and insulation, resulting in poor synergy between these materials, complex joint sealing structures, and a gradual decline in waterproofing and insulation performance over time. Due to the lack of reliable and durable joint sealing nodes and effective roof drainage measures, prefabricated modular data center roofs typically require a combination of container joint sealing and a gable roof design. However, this solution is complex to construct and has a long construction period, partially offsetting the advantages of rapid deployment of prefabricated modular data centers. It also increases costs and reduces typhoon resistance, making it an unsuitable solution for addressing the drainage and waterproofing issues of prefabricated modular data center roofs. Utility Model Content

[0005] The technical objective of this utility model is to address the above-mentioned shortcomings by providing a prefabricated modular data center roof joint sealing node and data center. It adopts a unified structure for roof joint insulation and waterproofing, and the joint gaps can be dynamically repaired. The roof box joint sealing node alone can achieve reliable and durable roof waterproofing and insulation requirements.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A prefabricated modular data center roof joint sealing node includes a joint cap installed above the roof joint, and an airbag sealing body, sealing accessories, and a limiting plate located below the joint cap.

[0008] The airbag sealing body includes an airbag shell, filling gas and an air nozzle. The airbag sealing body is filled into the gap between the roof box beams. Its cross-section is capsule-shaped and the interior is filled with filling gas with heat insulation properties. Under the action of the filling gas, the airbag shell continuously expands and squeezes against the side wall of the roof box beam and the arc-shaped limiting plate to form a seal, thereby playing a role in waterproofing and heat preservation.

[0009] The sealing accessories include a solenoid valve, a pressure sensor, a controller, and a compressor. These components enable real-time monitoring and dynamic pressure compensation of the airbag sealing body, ensuring a long-lasting and stable sealing effect. The pressure sensor is fixed at the upper air nozzle of the airbag sealing body and connected to the controller via a signal transmission line. It dynamically monitors the airbag sealing body pressure and transmits the data to the controller. The solenoid valve is located between the air nozzle of the airbag sealing body and the compressor pipeline, and is connected to the controller via a signal control line. The solenoid valve can open or close according to controller commands, achieving dynamic pressure compensation within the airbag sealing body. The compressor adjusts the filling gas pressure according to controller commands, and dynamically compensates for the pressure within the airbag sealing body through the transmission pipeline and the solenoid valve.

[0010] The controller serves as the control center for the sealing accessories. It receives feedback signals from the pressure sensor and controls the solenoid valve and compressor to achieve real-time monitoring and dynamic compensation of the airbag sealing body pressure.

[0011] Preferably, the filling gas is argon.

[0012] Preferably, the limiting plate is welded and fixed to the roof box beam; when the two boxes are spliced, the limiting plates on the roof box beams on both sides combine to form the limiting device of the airbag sealing body.

[0013] Preferably, the limiting plate is an arc-shaped limiting plate.

[0014] Preferably, the arc-shaped limiting plate includes an upper arc-shaped plate and a lower arc-shaped plate. After the two boxes are spliced ​​together, the arc-shaped limiting plate forms a limiting position on the upper and lower parts of the airbag sealing body, respectively.

[0015] Preferably, the joint cap is made of stainless steel sheet bent into shape, with a slope at the top for drainage at the joint, and the lower part is fixed to the roof beam of the box body by bolt fasteners.

[0016] Preferably, the lower part of the joint cap is bent, and the bent shape matches the top and side surfaces of the box roof beam, and is fixed to the side surface of the box roof beam by bolt fasteners.

[0017] Preferably, when the airbag sealing body is inserted into the gap between the roof box beams, it is pre-filled with a portion of the filling gas, and the filling gas continues to be filled after insertion. The filling gas is continuously injected into the airbag sealing body through the sealing auxiliary system, causing it to expand continuously. As the pressure increases, the airbag sealing body shell is continuously squeezed against the roof box beams and the limiting plate, and the contact between them becomes tighter and tighter, resulting in a better sealing effect. After reaching a certain pressure, when there is no gap between the airbag sealing body shell and the roof box beams and the limiting plate, the solenoid valve is closed and the inflation stops.

[0018] The sealing components, including a pressure sensor, solenoid valve, compressor, and controller, enable real-time monitoring and dynamic pressure compensation of the airbag sealing body, ensuring a consistently stable sealing effect. The pressure sensor monitors the pressure inside the airbag sealing body in real time and transmits this information to the controller. When the controller detects low pressure inside the airbag sealing body, it controls the compressor to start argon gas compression and simultaneously opens the solenoid valve to replenish pressure to the airbag sealing body through the transmission pipeline. When the pressure of the airbag sealing body reaches the set value after replenishment, the controller shuts off the compressor and solenoid valve, ending the pressure replenishment process.

[0019] This utility model also claims protection for a prefabricated modular data center, comprising multiple splicing boxes, wherein the splicing of each box adopts the aforementioned roof splice sealing node.

[0020] Compared with existing technologies, the prefabricated modular data center roof joint sealing node and data center of this utility model have the following advantages:

[0021] This utility model adopts a "prevention and drainage combined" design concept, introduces an airbag sealing body to achieve dynamic repair of joint gaps, and uses high-durability stainless steel materials to achieve reliable and durable roof waterproofing requirements solely through the sealing nodes of the roof box joints. It is easy to install, quick to deploy, has superior overall performance, and is suitable for a wide range of applications. Attached Figure Description

Detailed Implementation

[0025] This utility model embodiment provides a prefabricated modular data center roof joint sealing node, such as... Figure 1 As shown, it includes an airbag sealing body 2, a sealing accessory 3, a limiting plate 4, a joint cap 1, and bolt fasteners 6. The joint cap 1 is installed above the roof joint, and the airbag sealing body 2, the sealing accessory 3, and the limiting plate 4 are located below the joint cap 1.

[0026] The airbag sealing body 1 has a capsule-shaped cross-section and is filled into the gap between the roof box beams. It is filled with argon gas 21 with excellent heat insulation properties. The outer shell 22 of the airbag sealing body expands continuously and squeezes against the side wall of the roof box beam 5 and the limiting plate 4 to form a seal, which plays a role in waterproofing and heat preservation.

[0027] The limiting plate 4 is an arc-shaped component, which is welded and fixed to the roof box beam 5. After the two boxes are spliced, the limiting plates 4 on the roof box beams 5 on both sides are combined to form the limiting device of the airbag sealing body 2.

[0028] The arc-shaped limiting plate includes an upper arc-shaped plate and a lower arc-shaped plate. After the two boxes are spliced ​​together, the arc-shaped limiting plate forms a limiting position on the upper and lower parts of the airbag sealing body 1, respectively.

[0029] The sealing accessory includes components such as a solenoid valve 31, a pressure sensor 32, a transmission pipe 33, a transmission line 34, a controller 35, and a compressor 36, which realize real-time pressure monitoring and dynamic pressure compensation of the airbag sealing body 2, ensuring a long-lasting and stable sealing effect.

[0030] The pressure sensor 32 is fixed at the air nozzle 23 on the upper part of the airbag sealing body and is connected to the controller 35 through the transmission line 34. It can dynamically monitor the pressure of the airbag sealing body and transmit the data to the controller 35.

[0031] The solenoid valve 31 is located between the air nozzle 23 of the airbag sealing body and the compressor transmission pipeline 33. It is connected to the controller 35 through the signal transmission line 34. The valve can be opened or closed according to the instructions of the controller 35 to achieve dynamic pressure compensation inside the airbag sealing body 1.

[0032] The compressor 36 can adjust the argon pressure according to the instructions of the controller 35, and realize dynamic compensation of the pressure inside the airbag sealing body through the transmission pipeline 33 and the solenoid valve 31.

[0033] The controller 35 is the control center of the sealing accessory. It receives the feedback signal from the pressure sensor 32 and controls the solenoid valve 31 and the compressor 36 to realize real-time monitoring and dynamic compensation of the pressure of the airbag sealing body.

[0034] The joint cap 1 is made of bent stainless steel sheet, with a slope at the top to facilitate drainage at the joint, and the lower part is fixed to the box roof beam 5 by bolt fasteners 6. The lower part of the joint cap 1 is bent, and the bent shape matches the top and side surfaces of the box roof beam 5, and it is fixed to the side surface of the box roof beam 5 by bolt fasteners 6.

[0035] The application method and principle of the prefabricated modular data center roof joint sealing node are as follows:

[0036] The limiting plate 4 is welded and fixed to the corresponding position of the roof box beam 5. After the roof box is hoisted and placed, the arc-shaped limiting plates between the two roof box beams are combined into a limiting component to form the airbag sealing body 2.

[0037] The airbag sealing body 2 is pre-filled with some gas and inserted into the gap between the two roof box beams 5. Argon gas is continuously injected into the airbag sealing body 1 through the sealing accessory 3 system, causing it to expand continuously. As the pressure increases, the gap between the airbag sealing body shell 22 and the roof box beam 5 and the limiting plate 4 is continuously squeezed, and their contact becomes tighter and tighter, resulting in a better sealing effect. After reaching a certain pressure, the solenoid valve 31 is closed and the inflation stops.

[0038] Complete the installation of the joint sealing cap 1, and firmly fix the joint sealing cap 1 to the roof box beam 5 with bolts and fasteners 6.

[0039] The solenoid valve 31, pressure sensor 32, compressor 36, and controller 35 of the sealing accessory 3 enable real-time monitoring and dynamic pressure compensation of the airbag sealing body, ensuring a long-lasting and stable sealing effect. The pressure sensor 32 monitors the pressure inside the airbag sealing body 2 in real time and transmits it to the controller 35. When the controller 35 detects that the pressure inside the airbag sealing body 2 is low, it controls the compressor 36 to start argon gas compression and simultaneously opens the solenoid valve 31, replenishing pressure to the airbag sealing body through the transmission pipeline 33. When the pressure of the replenished airbag sealing body reaches the set value, the controller 35 shuts down the compressor 36 and the solenoid valve 31, ending the pressure replenishment process.

[0040] This utility model embodiment also provides a prefabricated modular data center, including multiple splicing boxes, and the splicing of each box adopts the roof splicing sealing node described in the above embodiment.

However, it should be understood that this utility model is not limited to the specific embodiments described above. Based on the disclosed embodiments, those skilled in the art can arbitrarily combine different technical features to achieve different technical solutions.
