Abstract
Description
Technical Field
[0001] This utility model relates to the field of electromagnetic shielding room technology, specifically a steel plate assembled electromagnetic shielding room structure. Background Technology
[0002] Patent CN104244687B discloses an electromagnetic shielding room, comprising: a shielding shell; the interior of the shielding shell encloses a sealed electromagnetic shielding space, the walls of which, from the inside out, include: a permalloy shielding interlayer, a support layer, and an aluminum plate shielding interlayer, the permalloy shielding interlayer and the aluminum plate shielding interlayer being fixed to the inner and outer sides of the support layer, respectively. It not only uses permalloy to shield low-frequency magnetic fields but also uses aluminum plates for high-frequency electromagnetic field shielding, improving the high-frequency shielding effect. In the range greater than 1kHz, the shielding effect is significantly improved, with a shielding factor >70dB, and the shielding factor increases with increasing frequency. Active compensation is used to offset part of the geomagnetic field; below 1Hz, the compensation factor generated by the active compensation technology is 12dB, effectively improving the low-frequency performance of the shielding room.

Detailed Implementation
[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0023] This utility model provides a steel plate assembled electromagnetic shielding room structure. Please refer to [link / reference]. Figure 1-4 The device includes a modular steel plate splicing shell, which comprises a top support plate 1, a rear support plate 6, and a bottom support plate 3. The top support plate 1, the rear support plate 6, and the bottom support plate 3 are integrally formed. A left support plate 2 is hinged to the left side of the rear support plate 6, and a right support plate 5 is hinged to the right side of the rear support plate 6. A door panel 4 is hinged to the end of the left support plate 2. The top support plate 1, the rear support plate 6, and the bottom support plate 3 are a single unit, and the unit is U-shaped.
[0024] The top support plate 1, rear support plate 6, bottom support plate 3, left support plate 2, right support plate 5, and door panel 4 are all made of steel.
[0025] The top support plate 1 and the left support plate 2 are provided with corresponding pin holes, and the top support plate 1 and the left support plate 2 are connected by pins 7; the top support plate 1 and the right support plate 5 are also provided with corresponding pin holes, and the top support plate 1 and the right support plate 5 are connected by pins 7; therefore, both the left support plate 2 and the right support plate 5 can be opened, thereby increasing the opening of the shielding room and facilitating operation.
[0026] The inner sides of the top support plate 1, rear support plate 6, bottom support plate 3, left support plate 2, right support plate 5, and door panel 4 are all bolted with a protective layer 11. The inner side of each protective layer 11 is bolted with an aluminum plate shielding layer 10. The inner side of each aluminum plate shielding layer 10 is bolted with a support layer 9. The inner side of each support layer 9 is bolted with a permalloy shielding layer 8. A compensation coil layer 12 is provided between the modular steel plate spliced outer shell and the protective layer 11. The design of the compensation coil layer 12 is the same as that of the patent cited in the background art. Both the protective layer 11 and the support layer 9 are made of insulating material. The aluminum plate shielding interlayer is composed of multiple layers of aluminum plates spliced together, with wood material used to fill the spaces between the two layers. The entire aluminum plate shielding interlayer uses aluminum plates with dimensions of 1.25m*2.5m*6mm, resulting in a final spliced size of approximately 2.5m*2.5m*2.5m. The aluminum shielding interlayer can shield high-frequency electromagnetic waves with a shielding depth of less than 6mm, i.e., high-frequency electromagnetic field interference with a frequency greater than about 5kHz, and can also shield electrostatic or quasi-electrostatic field interference.

In order to increase the size of the opening of the shielded room, the latch 7 can be pulled out, and the left support plate 2 and the right support plate 5 can be opened like a door panel, making the operation more convenient.

In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
