Description

Technical Field

[0001] This utility model relates to the field of electromagnetic shielding room technology, and in particular to a modular assembled electromagnetic shielding room. Background Technology

[0002] With the rapid development of electronic information technology, various electronic devices are increasingly widely used in industrial production, scientific research, communication transmission, and military defense. However, electronic devices generate electromagnetic radiation during operation and are also susceptible to interference from external electromagnetic signals. This not only affects the normal operating accuracy and stability of the equipment but may even lead to serious problems such as data transmission errors and equipment malfunctions. Therefore, providing an environment that can effectively isolate electronic devices from electromagnetic interference is crucial, and electromagnetic shielding rooms have emerged to address this need.

[0003] Traditional electromagnetic shielding rooms typically employ integral welded or fixed assembly structures. The construction of these rooms requires extensive on-site welding and cutting, resulting in long construction periods, high skill requirements for construction personnel, and significant limitations imposed by site conditions. Once completed, the structure remains fixed. Subsequent adjustments to the room's size or layout, or relocation to another location, often necessitate destructive demolition of the original structure, leading to substantial material waste and significant expenditure of manpower, resources, and time.

[0028] Reference Figure 1-3 A modular assembled electromagnetic shielding room is composed of a base 1, a shielding wall module 2, a shielding top module 3, a shielding bottom module 4, a shielding door module 5, and a ventilation and filtration module 6. The ingenious design between the modules ensures excellent shielding effect and practical performance.

[0029] The base 1, serving as the fundamental support structure for the entire shielded room, is welded from high-strength steel. Its bottom undergoes special anti-slip and anti-corrosion treatment, ensuring it is firmly fixed to the ground and providing a solid and reliable support platform for the installation of the modules above. Simultaneously, the upper surface of the base 1 is precisely machined with positioning holes and connecting grooves, allowing for precise docking with the shielding bottom module 4, thus guaranteeing the installation accuracy of the entire shielded room.

[0030] The shielding bottom module 4 is detachably mounted on the base 1. Made of high-quality alloy material, it boasts excellent flatness and load-bearing capacity. It is connected to the base 1 using high-strength bolts, ensuring secure installation and easy disassembly for future maintenance and relocation. The surface of the shielding bottom module 4 is electroplated, further enhancing its conductivity and corrosion resistance, effectively preventing external electromagnetic interference from penetrating from the bottom.

[0031] The shielding wall module 2 is detachably installed on the shielding base module 4. It includes a frame and a shielding plate fixed to the frame. The frame is made of high-strength steel, which undergoes a rigorous heat treatment process, resulting in extremely high structural strength and stability. It can withstand the weight of the shielding plate and other components while effectively resisting external impacts. The frame has connecting parts at its edges, with connecting holes. The connecting parts are detachably connected to adjacent modules via fasteners that pass through the connecting holes. This connection method makes the installation and disassembly of the modules simple and quick, greatly improving construction efficiency.

[0032] The shielding panel has a multi-layered structure, consisting of a metal shielding layer, an insulation layer, and a protective layer from the inside out. The metal shielding layer is made of high-purity copper, which possesses excellent conductivity and electromagnetic shielding properties, effectively blocking the penetration of external electromagnetic signals and ensuring that equipment inside the shielded room is not interfered with. The insulation layer is made of high-temperature resistant and aging-resistant insulating materials, effectively isolating the metal shielding layer from external conductors, preventing leakage, and ensuring the safe use of the shielded room. The protective layer is made of wear-resistant and corrosion-resistant materials, protecting the shielding panel from external physical damage and chemical corrosion, extending its service life.

[0033] The shielding top module 3 is detachably mounted on the shielding wall module 2. Its structure is similar to that of the shielding wall module 2, also consisting of a frame and shielding plates. The frame is made of lightweight, high-strength alloy material, reducing overall weight while ensuring sufficient structural strength. The shielding plates also employ a multi-layered design, providing excellent electromagnetic shielding and protection performance. The connection between the shielding top module 3 and the shielding wall module 2 uses the same method as between the two modules, ensuring a secure and airtight connection.

[0034] The shielded door module 5 is detachably installed on the shielded wall module 2. It includes a door frame and a door panel. The door frame is detachably connected to the shielded wall module 2 using fasteners, making installation and disassembly convenient. The door panel is connected to the door frame via high-strength hinges, which undergo special rust-proofing treatment to ensure the door panel can open and close flexibly. A conductive shielding strip is installed on the contact surface between the door panel and the door frame. The conductive shielding strip is made of highly elastic conductive material, possessing excellent conductivity and sealing properties. When the door panel is closed, the conductive shielding strip fits tightly between the door panel and the door frame, effectively eliminating electromagnetic leakage at the door gap and ensuring the shielding effect of the shielded door.

[0035] The ventilation and filtration module 6 is detachably installed on the shielding wall module 2. It includes a ventilation channel running through the shielding wall module 2 and an electromagnetic shielding filter installed within the ventilation channel. The ventilation channel is rationally designed to ensure air circulation within the shielding room, providing a good ventilation environment for the equipment and personnel inside. The electromagnetic shielding filter adopts a multi-layer metal mesh structure, possessing extremely high electromagnetic shielding efficiency, effectively blocking external electromagnetic interference from entering the shielding room through the ventilation channel while ensuring ventilation. The installation position of the ventilation and filtration module 6 is carefully designed to maximize ventilation effect without affecting the overall structure and shielding performance of the shielding room.

[0036] In addition, conductive seals are installed at the connections between the shielding wall module 2, shielding top module 3, shielding bottom module 4, shielding door module 5, and ventilation and filtration module 6. These conductive seals are made of highly conductive and elastic materials, possessing excellent sealing and conductivity properties. They effectively fill the gaps at the connections between modules, eliminate electromagnetic leakage, and ensure that the entire shielding room forms a complete electromagnetic shield, achieving the best shielding effect.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
