Embodiment
Below, the specific embodiment of the present invention is described in detail with reference to accompanying drawing, but it is not as limiting to the invention.
As shown in figure 1, the embodiment provides a kind of high temperature superconducting magnetic suspension system, the high-temperature superconducting magnetic levitation
System is applied to magnetic suspension train, and the high temperature superconducting magnetic suspension system includes：Low-temperature (low temperature) vessel 3, tracks of permanent magnetism 4, high-temperature superconductor
Block 2.Low-temperature (low temperature) vessel 3 is used for the bottom for being arranged at magnetic suspension train；Hts bulk 2, it is arranged in the low-temperature (low temperature) vessel 3；Forever
Magnetic orbital 4 is located at the lower section of the low-temperature (low temperature) vessel 3, and forming magnetic flux nail with the hts bulk 2 beats effect, wherein：The height
Temperature superconductive block 2 is coated with non-magnetic metal material to increase the effect between the hts bulk 2 and the tracks of permanent magnetism 4
Damping.Preferably, the hts bulk 2 is coated by copper box 1.And the copper box 1 is formed by multiple copper sheet weldings, copper box 1
Sealing, the thickness of copper sheet is 0.1-0.5mm.
Understood according to above-mentioned, the non-magnetic metal material of the outer cladding of hts bulk 2, the non-magnetic metal material both can be
Change and vortex is produced in external magnetic field, play a part of eddy current retarder, can be that the offer of hts bulk 2 one is fully sealed again
Environment, completely cut off air, avoid being oxidized, extend bulk service life.
On the one hand the present invention can improve the damping of high temperature superconducting magnetic suspension system, make by the use of copper box 1 as eddy current retarder
System is by can return to equilbrium position as early as possible during external interference.On the other hand, also can starvation, play protection bulk work
With extending the service life of bulk.
In the actual installation process of hts bulk 2, stablized installation on the premise of hts bulk 2 is not damaged
As technological difficulties.Hts bulk of the prior art, because outside does not have coated copper box 1, generally utilize pressing device
In pressing plate fix, and the present invention hts bulk 2 be coated with copper box 1, if the hts bulk 2 still utilizes prior art
In pressing device fix, because the quality of copper is softer, be easily compacted device damage.Therefore, the high-temperature superconductor magnetic of the present invention
Suspension system also includes being used for the fixing device for fixing hts bulk 2.Specifically, fixing device includes upper end opening, lower end
The end cap 13 of casing 11 and closure casing 11 upper end formed with ring flange 18, the casing 11 is interior to be used to set hts bulk
2, casing 11 is fixed on the bottom of low-temperature (low temperature) vessel 3 by wearing the fastener of ring flange 18, and the interior shape of casing 11 surpasses with high temperature
The profile of guide block 2 is consistent, and is more than hts bulk 2, and four walls in casing 11 are provided with stabilized zone 12 made of elastomeric material,
Such as stabilized zone 12 made of elastomeric material, what the stabilized zone 12 was limited is used to accommodate the hts bulk 2 for being coated with copper box 1
Space be slightly larger than and be coated with the hts bulk 2 of copper box 1 so that be coated with copper box 1 hts bulk 2 can freely from
Take out or be put into the space.The key of the fixing device is：The height of the stabilized zone 12 is set to be higher than in being coated with copper box 1
Hts bulk 2.In this way, when being coated with the hts bulk 2 of copper box 1 as in space, and end cap 13 is buckled in the upper of casing 11
Behind end, the lower end pushing and pressing stabilized zone 12 of end cap 13, because stabilized zone 12 is made up of elastomeric material, so that the height of stabilized zone 12
The size spent on direction reduces, and because the volume of stabilized zone 12 will not change, so that stabilized zone 12 is perpendicular to height
The direction size increase of degree, so that the space for accommodating hts bulk 2 reduces, surrounding of the stabilized zone 12 in hts bulk 2
Uniform extrusion cladding has the hts bulk 2 of copper box 1, so as to which the hts bulk 2 for being coated with copper box 1 be stably fixed to
In casing 11, and because the elastomeric material of such as rubber is softer, the copper box 1 outside hts bulk 2 will not be caused to damage.End cap 13
It is bolted on the upper end of casing 11.To prevent the in the vertical direction of hts bulk 2 from vibrating, the lower end of end cap 13
Neck is offered on face, the upper end of a compressor arm 14 is stretched in neck, is provided with neck for pushing down on to compressor arm
14 stage clip 16, the lower end of compressor arm 14 are provided with platen 15, and the lower surface of platen 15 is provided with pad 17 made of elastomeric material.
In this way, platen 15 compresses hts bulk 2 under the effect of stage clip 16 with certain pretightning force, so as to prevent hts bulk 2 to exist
Sharp pounding on vertical direction, pad 17 have protective effect to copper box 1.
Above example is only the exemplary embodiment of the present invention, is not used in the limitation present invention, protection scope of the present invention
It is defined by the claims.Those skilled in the art can make respectively in the essence and protection domain of the present invention to the present invention
Kind modification or equivalent substitution, this modification or equivalent substitution also should be regarded as being within the scope of the present invention.
