Specific embodiment
The floated cryogenic liquid storage of liner of the invention and shipping container are done in detail with reference to the accompanying drawings and examples
Illustration and description.
As shown in Figure 1, the storage of liner of the invention floated cryogenic liquid and shipping container, vessel is by outer gallbladder 1, interior
Gallbladder 2 forms.Vacuum cavity is formed between outer gallbladder 1 and liner 2.Liner 2 is un-conducted magnetic material, on its external wall, except arrangement tradition
Heat-insulating material outside, it is also main its underpart and top respective location by the higher structure of pyroconductivity be fixed with it is several from
Scattered superconductor 3, superconductor 3 have good thermally contact with liner 2.On outer 1 inner wall of gallbladder and 3 corresponding position of superconductor, cloth
It is equipped with permanent magnet 4.Permanent magnet 4 and superconductor 3 form super-conductive magnetic suspension unit.
As shown in Figure 2,3, in the vacuum cavity between inside and outside gallbladder, the left and right sides is symmetrically arranged with removable rigid support
Device, the removable rigid support device include the guide pipe 6 arranged on liner 2, the pull rod 7 being arranged in guide pipe 6 inside and
The inclined wedge 5 being arranged below the idler wheel 8 and idler wheel 8 that the hinged lever 9 in 7 one end of pull rod, 9 lower end of lever are installed.Above structure is total
With the positioning support structure of liner is constituted, for realizing rigid contact and suspended transformation between inside and outside gallbladder, the removable rigidity
The position of support device is higher than lower part and mainly carries superconducting magnetic levita unit.
Guide pipe 6 and liner 2 are connected as one, and with liner have it is good thermally contact, the both ends open of guide pipe 6,
Inner cavity and vacuum chamber communicate.Pull rod 7 deforms big material by contracting on cooling deformation ratio liner 2 and is made, and one end and guide pipe are rigid
Property fix, the other end and lever 9 are hinged.It is connected, can be rotated around pin shaft, lever 9 by pin shaft 10 and liner 2 in the middle part of lever 9
Lower end connected by shaft and idler wheel 8；Idler wheel 8 can be rotated around the shaft on lever.Both ends and liner 2 in guide pipe 6
The section of one fixed width is equipped between outer wall, lever 9 and articulated structure are located in the section, and the width in the section should meet drawing
When 7 deformation of bar, activation lever 9 rotate it is unrestricted, thus realize idler wheel 8 and the separation of inclined wedge 5 with contact.
As a kind of preferred embodiment of the invention, being set inside guide pipe 6 there are two pull rod 7, two pull rods are symmetrical arranged, and two
One end of a pull rod is rigidly fixed in the middle part of guide pipe 6 respectively, as shown in figure 1 shown in fixed point 12.The other end passes through hingedly respectively
Axis 11 is connect with lever 9, and entire support device is a symmetrical structure.Two inclined wedges 5 of 8 lower section of idler wheel are oppositely arranged, i.e., and two
