Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with specific embodiment, and reference
Attached drawing, the present invention is described in further detail.
As a preferred embodiment of the present invention, the invention discloses a kind of ultralow temperature double cloth heat-insulation system,
Including：Stent 1, servo motor 2, shaft coupling 3, worm screw 4, turbine 5, support arm 6, flag-shaped cool guide sheet 7, isolation channel 8, outer shield
Cover 9, internal layer shielding case 10, conduction cooling platform 11 and working media 12, wherein, servo motor 2 is fixed on stent 1, servo motor 2 with
Worm screw 4 is connected by shaft coupling 3；Two turbines 5 on the direction vertical with worm screw 4 with worm screw 4 simultaneously engaged transmission；Two supports
Arm 6 is coaxial connected with two turbines 5 respectively, and is rotated simultaneously with turbine 5；Heat dam 8 is opened up on support arm 6, flag-shaped cool guide sheet 7 is logical
It crosses screw and is fixed on 6 side of support arm, wherein flag-shaped end 7a is connected in support arm 6 on the inside of one end of turbine 5；Tail end 7b consolidates
It is scheduled on the inside of heat dam 8 on support arm 6；Outer shield cover root 9a is fixed on the outside of the heat dam 8 on support arm 6；It is interior
Layer shielding case root 10a is fixed on the inside of heat dam 8 on support arm 6, and be connected with the tail end 7b of flag-shaped cool guide sheet 7；Outer layer
It is not contacted between shielding case 9 and internal layer shielding case 10, forms gap；Conduction cooling platform 11 is fixed on stent 1, internal and ultralow temperature
The Conduction At Low Temperature component of system is connected, and the height of conduction cooling platform must ensure when shielding case is closed and the flag-shaped end of flag-shaped cool guide sheet 7
7a is in contact；12 one end of working media is stretched into stent 1 to be connected with ultra-low temperature systems Conduction At Low Temperature component, and the other end is exposed to work
Make in environment, when shielding case is closed, is placed exactly in symmetrical shielding case and is closed in the cavity to be formed, so as to reach heat preservation
Purpose.
The present invention system work when, servo motor 2 by shaft coupling 3 drive worm screw 4 rotate, two turbines 5 perpendicular to
Worm axis direction and worm engaging, therefore worm screw 4 can drive two turbines 5 to rotate simultaneously, two turbines, 5 direction of rotation just phase
Instead.Support arm 6 is coaxially connected with turbine, therefore the rotation of turbine 5 can drive support arm 6 to rotate together, since two turbines 5 turn to
On the contrary, therefore two support arms, 6 symmetrical open or close.Since outer shield cover 9 and internal layer shielding case 10 are fixed on support arm 6
On, therefore, two outer shield covers 9 and internal layer shielding case 10 are opened simultaneously or are closed with two support arms 6.When double cloth closes
During conjunction, the flag-shaped cool guide sheet flag-shaped end 7a and the conduction cooling platform 11 that are fixed on two support arms 6 pass through the elastic element on conduction cooling platform 11
It is in close contact, since the inside of conduction cooling platform 11 is connected with the Conduction At Low Temperature component of ultra-low temperature systems, heat can be along leading
Cold bench 11 is transmitted to the flag-shaped cool guide sheet 7 on support arm 6, simultaneously because flag-shaped cool guide sheet tail end 7b and 10 phase of internal layer shielding case
Even, therefore, heat can be transmitted to internal layer shielding case 10 from flag-shaped cool guide sheet 7, so as to be symmetrically closed in internal layer shielding case 10
When, form cryoprotection environment.Outer shield cover 9 is located at 8 both ends of heat dam, therefore outer layer screen respectively with internal layer shielding case 10
It covers 9 internal layer shielding case 10 of cover not contact, there is gap in centre, while support arm 6, using heat-insulating material, therefore, outer shield cover 9 is protected
Normal temperature state is held, gap is formed between internal layer shielding case 9 and is isolated, normal temperature environment can be prevented to super in internal layer shielding case 9
Low temperature environment forms heat radiation；12 inside of working media is connected with the Conduction At Low Temperature component of ultra-low temperature systems, such working media
Low-temperature condition is remained in, and the cavity to be formed is closed in two double cloths, can prevent working media from condensing.
It when medium is started to work, is rotated by turbine 5 and two support arms 6 is driven to rotate, so as to drive the bilayer being connected with two support arms 6
Shielding case is symmetrically opened rapidly, so as to which medium be made to expose rapidly in the work environment.
The present invention realizes that working media ultralow temperature is kept by double-layer structure shielding case, by the way that arm contact is supported to pass cold realization
Double cloth is separated to form gap, passes through servo motor by internal layer shielding case Conduction At Low Temperature by opening heat dam on support arm
Driving turbine and worm transmission realizes that shielding case quickly opens and closes.
