Description
Technical field
The invention belongs to a kind of Collapsible building that can provide special protection, and in particular to a kind of electromagnetic screen
Cover tent.
Background technology
Electromagnetic shielding tent can not only prevent the electromagnetic information in tent from revealing, and be applied to army's electricity consumption
Son confrontation, can prevent interference of the electromagnetic information to tent inner facility outside tent, can be also used for point
Hold the observing and controlling of weapon.At present, screened room or military shielding shelter are mostly rigid structural, mostly using steel plate,
Copper coin or aluminium sheet are also shielding material with copper mesh as shielding material, some.This kind of screened room or shielding
Shelter not only complex manufacturing technology, long construction period, it is impossible to folding is carried with, and maintenanceability is poor, and
And shield effectiveness is poor, generally respectively less than 40dB.
United States Patent (USP) US6068009A discloses a kind of flexible electrical signal shielding cover Portable tent component, i.e.,
Free shielded, portable tent assembly with flexible electronic signal shielded
Enclosure, it mainly includes support, the tent shielding cloth being arranged on cradle top surface, bottom surface and side,
Shield door is provided with the side of tent shielding cloth, described tent shielding cloth is sewed by metal-nylon fiber
Form.The tent can provide the electromagnetic shielding space of a closing in paulin, to prevent space electricity in paulin
The leakage of magnetic information and the invasion interference of external electromagnetic information, are not provided normal for personnel and equipment in tent
The shielding device used.In Chinese periodical《Hosiery industry》Publication has " stainless steel on 5th phases in 2000
Application of the fiber in anti-electromagnetic radiation ", claim stainless steel fibre that there is natural fiber or staple fibre in literary
Performance, can spin, can nonwoven, be mainly used in anti-static fabric and electromagnetic wave radiation resistance fabric.Spin
In fabric add 5%~20% stainless steel fibre after, its fabric when 3000~10000Hz frequency ranges are tested,
Pad value is up to more than 25dB.Although this stainless steel fibre can be used as electromagnetic shielding tent cloth, its
Shield effectiveness is still less than 40dB, and because the frequency of its shielding is 3000~10000Hz, shielding frequency
The frequency of section is relatively low, is not the working frequency range of military equipment, it is impossible to as military electromagnetic shielding tent cloth.
For suitable for military equipment high-frequency microwave particularly frequency range in 30MH2~8GH2Shielding tent cloth does not appear in the newspapers
Road.
The content of the invention
It is an object of the invention to provide one kind, not only manufacture craft is simple, short construction period, can fold with oneself
Carry, be easy to repair, and shield effectiveness is got well and is provided with the military electromagnetic shielding tent of shielding device.
What the present invention was realized in：A kind of military electromagnetic shielding tent, it includes tent bracket, arrangement
Tent shielding cloth on tent bracket top surface, bottom surface and side, screen is provided with the side of tent shielding cloth
Cover door.Wherein, described tent shielding cloth is fine by soft and with high shield effectiveness pure stainless steel
Dimensional fabric is formed with pure stainless steel fibre sewing thread sewing fabric；Described shield door is door curtain shape, its top
Connected together with tent shielding cloth, the U-shaped crack between a door and its frame shielding between its side and base and tent shielding cloth
Slide fastener connects, and in the outside of U-shaped crack between a door and its frame covered with U-shaped left front, also is provided with left front with shielding slide fastener
The U-shaped seam corresponding with U-shaped crack between a door and its frame of connection, described shielding slide fastener is in pure stainless steel fibre fabric
Withheld on zipper strip made of copper tooth.Shielding camera bellows is additionally provided with tent bracket and tent shielding cloth, it
Including the casing made of steel plate and upper lid, it is divided into two chambers by shielded partitions in casing, in a chamber
It is interior, power-supply filter and traffic filter are installed in shielded partitions side, in the front and rear end of casing
On be separately installed with waveguide and waveguide window, ventilation unit is installed, waveguide stretches out on the bottom plate of casing
Tent is outer and is coated with tent shielding cloth, is provided with binding post in another chamber of casing, upper lid and
Seam crossing between casing and shielded partitions has shielding gasket.
The present invention makees tent shielding cloth with soft and with high shield effectiveness pure stainless steel fibre fabric, and
Provided with good shield door, making it, not only building technology is simple, short construction period, foldable to carry with,
It to be easy to repair, and there is good electromagnet shield effect, shield effectiveness is more than 65dB, and provided with confession
Personnel and the shielding device of equipment normal use, meet the quick construction under army's wartime adverse circumstances, make
With or dismounting transfer.
