Abstract
Description
Technical Field
[0001] This utility model relates to the field of electromagnetic shielding room technology, specifically a multifunctional electromagnetic shielding room. Background Technology
[0002] An electromagnetic shielding room is an enclosed space that blocks electromagnetic interference through a metal shield. It is widely used in electromagnetic equipment testing, information security, military and other fields. Typical applications include shielding of nuclear magnetic resonance equipment in scientific research laboratories and medical fields, as well as system protection of military facilities and prevention of server information leakage in data centers.
[0003] Currently, multi-functional electromagnetic shielding rooms have significant room for improvement in terms of safety protection and spatial layout. Although the main building structure generally uses installation materials with excellent fire resistance, during long-term operation, the densely arranged electromagnetic equipment inside the shielding room is prone to thermal runaway due to aging wiring and abnormal temperatures, which can lead to electrical fire risks. Of particular note is the lack of active fire-fighting facilities in traditional electromagnetic shielding rooms. They lack both intelligent fire monitoring systems and early fire extinguishing devices, making it difficult to effectively contain initial fires, often resulting in irreversible equipment damage and loss of experimental data. Regarding spatial planning, the conventional design's integrated large-space layout has inherent flaws. When multiple electromagnetic devices operate in parallel, the electromagnetic field coupling effect between devices is significantly enhanced, leading to mutual interference even when shielding effectiveness meets standards. This systematic interference not only affects the stability of equipment operation but also severely restricts the need for independent experiments in specific scenarios. When researchers need to perform precise tests on a single device, the electromagnetic radiation from adjacent devices creates superimposed background noise, directly damaging the electromagnetic purity of the experimental environment and causing systematic deviations in measurement data. This design flaw essentially limits the application value of electromagnetic shielding rooms in high-end scientific research and precision testing fields. Utility Model Content
[0004] The purpose of this invention is to provide a multifunctional electromagnetic shielding room to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional electromagnetic shielding room, comprising an outer frame, with multiple layers of outer shell panels fixedly connected to the outer surface of the outer frame, an entrance door provided on the outer shell panel on the front of the outer frame, a conveying pipe mounted on the top of the outer frame, a gas extinguishing system control box connected to the end of the conveying pipe, multiple vertical pipes penetrating the bottom of the conveying pipe, and sprinkler nozzles installed at the bottom ends of the vertical pipes, a cavity opened inside the outer frame, multiple heat-sensing fire detectors installed on the top of the inner side of the cavity, multiple first partitions provided on one side of the inner wall of the cavity, multiple second partitions provided on the other side of the inner wall of the cavity, a passageway opened between the first partitions and the second partitions, and a sliding door provided on one side of the passageway.
[0006] Preferably, rollers are installed at both the top and bottom of the sliding door, and a top rail is installed at the top of the first partition and the passageway. The rollers are rotatably connected to the top rail, and the sliding door is slidably connected to the top rail via the rollers.
[0007] Preferably, a right-angled bend plate is installed in the middle of the sliding door, and a groove is opened in the middle of the second partition plate. The sliding door is engaged with the second partition plate through the right-angled bend plate and the groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This multifunctional electromagnetic shielding room, through a heat-sensitive fire detector, a gas extinguishing system control box, delivery pipes, and sprinkler nozzles, can detect an initial fire caused by aging wiring within the shielding room. The heat-sensitive fire detector will promptly detect the fire and transmit a signal to the gas extinguishing system control box via cable. This will cause the gas extinguishing control box to deliver the gas extinguishing agent to the shielding room for active fire suppression, thereby effectively containing the initial fire and reducing the probability of equipment damage and data loss within the shielding room.
[0014] 2.

This reduces electromagnetic interference caused by adjacent devices inside the shielding room and removes the restriction on the need for independent experiments of electromagnetic equipment inside the shielding room, thereby enhancing the application value of the electromagnetic shielding room.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0023] like Figures 1 to 4 As shown, the multifunctional electromagnetic shielding room in this embodiment includes an outer frame 1. A multi-layer outer shell plate 3 is fixedly connected to the outer surface of the outer frame 1. An entrance door 2 is provided on the outer shell plate 3 on the front of the outer frame 1. A delivery pipe 4 is mounted on the top of the outer frame 1. A gas extinguishing system control box 17 is connected to the end of the delivery pipe 4. Multiple vertical pipes 5 pass through the bottom of the delivery pipe 4. Sprinkler nozzles 15 are installed at the bottom of the vertical pipes 5. A cavity 18 is opened inside the outer frame 1. Multiple heat-sensitive fire detectors 14 are installed on the top of the inner side of the cavity 18. Multiple first partitions 6 are provided on one side of the inner wall of the cavity 18. Multiple second partitions 13 are provided on the other side of the inner wall of the cavity 18. A passageway 10 is opened between the first partitions 6 and the second partitions 13. A sliding door 7 is provided on one side of the passageway 10.
[0024] Specifically, the separate design of the outer frame 1 and the outer shell panel 3 makes the shielded room easier to transport before installation. During installation, only the outer shell panel 3 needs to be welded to the outer frame 1. The function of the delivery pipe 4 is to ensure timely delivery of the gaseous fire extinguishing agent in the event of a fire within the shielded room, thereby facilitating the initial containment of the fire and minimizing potential losses. The gas extinguishing system control box 17 integrates a controller and solenoid valves, enabling the heat detector 14 to receive the signal and activate the solenoid valve, allowing the gaseous fire extinguishing agent to be delivered to the interior of the shielded room via the delivery pipe 4. The function of the sprinkler nozzle 15 is to... The gaseous extinguishing agent can be evenly sprayed into the cavity 18. The heat-sensing fire detector is a resettable cable-type linear shielded heat-sensing fire detector 14. It adopts a metal shielding layer design inside, which has strong anti-electromagnetic interference capability, so that the signal can be smoothly transmitted to the controller in the gas extinguishing system control box 17. The width and thickness of the first partition 6 and the second partition 13 are the same. The passageway 10 makes it easy for users to enter the divided individual spaces in turn, which facilitates subsequent experimental research. The width of the sliding door 7 is greater than the width of the passageway 10, so that the sliding door 7 can close the passageway 10, so that the interior of the shielded room can be divided into individual independent small spaces, which is conducive to the precise testing of individual devices.
[0025] Furthermore, rollers 8 are installed at both the top and bottom of the sliding door 7, and a top rail 16 is installed at the top of the first partition 6 and the passageway 10. The rollers 8 are rotatably connected to the top rail 16, and the sliding door 7 is slidably connected to the top rail 16 through the rollers 8. The function of the rollers 8 is to make the sliding door 7 smoother when pushed, thus making it easier for the operator to use.
[0026] Furthermore, a right-angled plate 9 is installed in the middle of the sliding door 7, and a groove 11 is provided in the middle of the second partition 13. The sliding door 7 is engaged with the second partition 13 through the right-angled plate 9 and the groove 11. After being twisted, the right-angled plate 9 can be inserted into the groove 11, so that the sliding door 7 can be temporarily locked at the passageway 10, which is conducive to the formation of a single small space in the shielded room.
[0027] Furthermore, multiple first partitions 6 and multiple second partitions 13 are symmetrically arranged inside the cavity 18, so that after the sliding door 7 moves from the first partition 6 to the passageway 10, the first partition 6, the sliding door 7, and the second partitions 13 can form a complete partition, thereby achieving the division of the electromagnetic shielding indoor space.
[0028] Furthermore, the heat-sensitive fire detector 14 is connected to the gas extinguishing system control box 17 via a cable, enabling normal signal transmission between the heat-sensitive fire detector 14 and the gas extinguishing system control box 17, thereby ensuring that the initial fire in the shielded room can be contained.
[0029] Furthermore, the interior of the delivery pipe 4 is connected to the interior of the vertical pipe 5, which runs through the top of the outer frame 1. The function of the vertical pipe 5 is to deliver the gaseous extinguishing agent to the sprinkler nozzle 15, so that the gaseous extinguishing agent can be sprayed out of the sprinkler nozzle 15.
[0030] Furthermore, the sliding door 7 is connected to the passageway 10 via the second partition 13. The cavity 18 contains an electromagnetic device 12. After the sliding door 7 moves to the passageway 10, it will stop at the passageway 10 under the restriction of the top rail 16, so that the passageway 10 can be blocked, thereby achieving the closure of the passageway 10 and realizing the physical isolation between adjacent electromagnetic devices 12.
[0031] The usage method of this embodiment is as follows: When using this multifunctional electromagnetic shielding room, the outer shell plate 3 needs to be installed and welded to the corresponding position on the outer frame 1, so that the entrance door 2 is located on the front of the outer frame 1. At the same time, the delivery pipe 4 and the vertical pipe 5 need to be installed on the top of the outer frame 1. After the installation of the electromagnetic shielding room is completed, the electromagnetic shielding room is powered on. When a fire occurs in a cavity 18 of the shielding room, the heat-sensing fire detector 14 installed in the cavity 18 will send a signal to the gas extinguishing system control box 17, so that the gas extinguishing system control box 17 opens the solenoid valve of the delivery pipe 4, so that the gas extinguishing agent enters the delivery pipe 4, and then enters the vertical pipe 5 along the delivery pipe 4, and then passes through the vertical pipe The spray nozzle 15 at the end of the shielding chamber sprays into the cavity 18, thus suppressing the initial fire in the shielding chamber. When it is necessary to use this shielding chamber for experimental research on a single electromagnetic device 12, the sliding door 7 can be pushed so that the sliding door 7 slides along the top rail 16 via the roller 8 until the sliding door 7 slides to the passageway 10 between the first partition 6 and the second partition 13. Then, the right-angled plate 9 on the sliding door 7 is twisted so that the right-angled plate 9 is locked into the groove 11. At this time, the sliding door 7 is locked at the passageway 10. The space inside the shielding chamber is divided into a separate enclosed small space by the first partition 6, the second partition 13 and the sliding door 7. Then, the research and experimentation on a single device can be carried out in this space.
[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
