Problems solved by technology

However, soft magnetic materials with high initial permeability are generally very sensitive to vibration, impact and other stresses. Because the outer material bears the self-weight stress of the inner material, its magnetic permeability decreases, which eventually leads to the overall shielding performance of the shielding room declining over time.

Embodiment Construction

[0023] Depend on figure 1 As can be seen from the shown embodiment, it includes a support screw 1, two sets of adjusting sleeves (adjusting sleeve I2 and adjusting sleeve II6), two sets of locking sleeves (locking sleeve I4 and locking sleeve II8) , Two sets of lock nuts (lock nut I3 and lock nut II7), two sets of load-bearing pads (load-bearing pad I5 and load-bearing pad II9) and a set of lock bolts 10. Two sets of adjustment sleeves (adjustment sleeve I2 and adjustment sleeve II6) are installed on the support screw 1 as the load-bearing nodes of the shielding layer, and the weight of each shielding layer inside is adjusted through the support screw 1 passing through the shielding layer. Transferred to the installation platform 11, the outermost shielding layer support node is the load-bearing pad II9; the load-bearing node is respectively formed by the two sets of locking sleeves and the Two sets of locking nuts are locked to ensure the reliability of the load-bearing node...

Abstract

The invention relates to an interlayer gravity support device for a magnetic shielding room. The interlayer gravity support device comprises a support screw rod and an adjusting sleeve, a locking nut, a locking sleeve, a locking bolt, bearing cushion blocks, a shielding layer and a mounting platform which are used together with the support screw rod, wherein the adjusting sleeve and the locking nut are arranged on the support screw rod so as to form a bearing node; the support screw rod penetrates through the shielding layer and is used for transferring the weight of the inner shielding layer endured by the bearing node to the mounting platform; the locking sleeve is used for locking the shielding layer; the bearing cushion block I and the bearing cushion block II are arranged on the support screw rod; the bearing cushion block II is locked on the mounting platform by the locking bolt. The interlayer gravity support device for the magnetic shielding room has the advantages of quick and convenient mounting and high reliability.

Description

technical field [0001] The invention relates to a gravity support device between the shielding layers of a multi-layer high-performance zero-frequency and weak magnetic shielding room, which belongs to the technical field of zero-frequency and weak magnetic field shielding, and is suitable for deriving the internal shielding layer of a multi-layer magnetic shielding room for zero-frequency and weak magnetic field protection Its own weight eliminates the stress effect of the inner shielding layer's own weight on the outer shielding layer material, so as to improve the overall shielding performance and reliability of the magnetic shielding room. [0002] technical background [0003] For the magnetic shielding room working in the earth's weak magnetic environment with an external magnetic field strength of about 50000nT, to obtain the shielding index of the indoor magnetic field strength below 100 nT, generally use soft magnetic materials with high initial magnetic permeability ...
