In order to guarantee that temperature and humidity and cleanliness of the dust-proof shed under any season and environmental condition in canopy meet human body needs And meeting installation requirement, the top of the left side canopy cloth 202 or right side canopy cloth 203 is provided with air inlet 11, air inlet 11 1 End is fixedly connected with outer canopy cloth 2, and the other end can be connected with the air cleaning outside canopy with air-conditioning device, so as to when necessary into canopy It is filled with the dry air after purifying temperature-regulating, to keep in canopy the cleanliness of air, temperature and humidity to meet the requirements and maintain always In slight positive pressure state, air inlet is closed by fastener when not used.
Top between the front side air column skeleton 101 and rear side air column skeleton 102 is provided with connecting band 12.For propping up Support outer canopy cloth 2.
Top surface canopy cloth 201, front side canopy cloth 204 and the rear side canopy cloth 205 is respectively that transparent TPU is made, to increase Translucency provides good working environment, the left side canopy cloth 202,203 and of right side canopy cloth to the installation personnel in dust-proof shed Sealing cuff 7 is respectively that Oxford cloth is made, and Oxford cloth is soft, light, and stickiness is good, increases sealing performance, alleviates dust-proof shed Weight.
Transparent window 10 there are two being respectively set on the left side canopy cloth 202 and right side canopy cloth 203, each transparent window 10 are all made of transparent TPU.Increase translucency, convenient for the situation in observation dust-proof shed.
The fastener 8 is the elastic band without the jag of elasticity or with elasticity.To entangle the installation of GIS opening Mouthful, realize sealing, it is air tight.
It is respectively detachable connection between each the sealing cuff 7 and left side canopy cloth 202 or right side canopy cloth 203.
It is connected between each the sealing cuff 7 and left side canopy cloth 202 or right side canopy cloth 203 by zipper 6.Work as sealing When cuff 7 is dirty or is broken, it is convenient for changing.
The outside of the front side canopy cloth 204 and rear side canopy cloth 205 is respectively arranged with thread gluing 9.For connecting its two sides Between dressing room and standby redundancy.
Extension is respectively arranged on the front side air column skeleton 101, rear side air column skeleton 102 and top air column skeleton 103 Ring 13.Rope will be connected on link 13, rope is fixed in neighbouring equipment, this dust-proof shed inclines when wind can be prevented big , and it is provided with link 13, manually when carrying this dust-proof shed, be moved easily.Link is set on the air column skeleton of top, Facilitate installation air monitoring device, video recording apparatus and illuminator.
Air column skeleton 1 uses folder screen cloth high-intensitive, that air-tightness is good and makes air column, this folder net with a thickness of 0.7mm Cloth is wear-resisting, anti-stab, fire-retardant, constitutes the air column skeleton 1 of dust-proof shed by the air column being connected to, and dust-proof shed is just in primary inflation 5 minutes It can erect and, and retentivity is fabulous, it is ensured that a week is indeformable, does not collapse.Thus also just completely need not be again It is inflated always using blower to keep the shape of dust-proof shed.Also It is not necessary to be supported with bracket inside dust-proof shed.
Since the GIS size of different manufacturers is different, the location and shape for all kinds of cuffs that dust-proof shed is connected with GIS are not yet Together, therefore by the outer canopy cloth 2 of dust-proof shed it is made into removably, as the GIS for different manufacturers, replaces outer canopy cloth 2.
The lighter in weight of entire dust-proof shed, a length is respectively 4 meters, 1.6 meters, 2.5 meters of dust-proof shed weight about It is 40 kilograms, it, can be very easily by it from GIS by unlocking the thread gluing of sealing cuff lower part after GIS bus is installed On remove.Bus interface takes around 1 day time at GIS installation one, it is therefore desirable to often mobile.
Skeleton material has excellent insulation performance and flame retardant property, can inflate use repeatedly;It is stretched with preferable Intensity and tearing strength, can an inflation, leak rate is less than 0.5%/day.Outer canopy cloth has airtight, waterproof spy Property, have the excellent performance of air insulated extraneous in dust-proof shed.
Dust-proof shed can open gas vent 5 after use, drain air in skeleton, entire dust-proof shed can compress, It is put into dedicated package after length, width and height are packaged into no more than 1 meter * 0.5 meter * 0.5 meter, can be easily put into the boot of car Transport.
Embodiment enumerated above is not to technical solution described in the invention only for understanding that the present invention is used Restriction, the those of ordinary skill in relation to field on the basis of the technical solution described in claim, can also make a variety of changes Change or deformation, all equivalent variations or deformation should all be covered within the scope of the claims of the present invention.The present invention is not Place is described in detail, is the well-known technique of those skilled in the art of the present technique.
