Description
Technical Field
The invention relates to the technical field of rail transit, in particular to a vacuum pipeline system of a high-speed magnetic suspension train.
Background
With the continuous progress of science and technology, the use requirements of high-speed magnetic suspension trains in social life are increasing day by day. The high-speed magnetic suspension train is subjected to air resistance in the running process, the influence of the air resistance is continuously increased along with the increase of the train speed, the optimization of the appearance design is difficult to meet the requirement of the train speed, and the method is particularly applied to the field of transonic speed. In order to solve the problem caused by air resistance, a navigation pipeline can be arranged outside a magnetic suspension train system, the air resistance borne by the train in the advancing process is reduced in a vacuumizing mode, and the speed of the train is further improved. The magnetic suspension train has no mechanical friction and no air resistance, so that the running speed of the high-speed magnetic suspension train reaches supersonic speed and feasibility is achieved, and the vacuum pipeline technology is an essential key technology of the ultrahigh-speed magnetic suspension train.
Currently, most vacuum pipes are designed as shown in fig. 1 (fig. 1 is a schematic diagram of a vacuum pipe system of a conventional high-speed magnetic levitation train). In combination with the current high-speed maglev train form (taking the form of a japanese maglev train as an example), the problems mainly exist in the following points:
(1) the problems of heat dissipation and insulation of the stator coil of the linear motor
A high-speed magnetic suspension train propulsion system generally uses a high-temperature superconducting linear synchronous motor, and for providing large thrust of a train, the current of a stator coil in a track beam is large, and the coil body generates heat seriously. In vacuum, the heat dissipation capability of the coil is reduced, and meanwhile, the turn-to-turn insulation capability of the coil is poor, so that the design of a stator coil of a linear motor system is difficult.
(2) Magnetic loss problem of superconducting magnet and vacuum steel pipe
In order to provide larger thrust of the train, the train generally carries a vehicle-mounted superconducting magnet with a larger magnetic field. In order to support the internal and external pressure difference caused by the vacuum pumping of the pipeline, the pipeline material is generally selected from metal materials such as steel and the like. The dynamic superconducting magnet generates eddy current on a steel-cast vacuum pipeline in the movement process, so that loss is generated, and the efficiency of a propulsion system is reduced.
(3) The vacuum pipeline has large volume and large construction cost and vacuumizing cost
As can be seen from FIG. 1, the vacuum pipes designed at present are large in size, and mainly envelope the rail system in which the train runs in a vacuum environment. The larger vacuum envelope environment is less economical from both the construction of the pipeline and the cost of evacuating the pipeline.

Therefore, the vacuum sealing pipeline can only envelop a high-speed magnetic suspension train, the propelling part (namely, the stator part of the superconducting linear synchronous motor) is isolated outside a vacuum layer, the volume of the vacuum pipeline can be reduced while a vacuum operation environment is provided for the high-speed magnetic suspension train, the construction cost and the vacuumizing cost are reduced, and the high-speed magnetic suspension train vacuum sealing pipeline has good economy.
For example, the superconducting vehicle magnet 2 may be a low temperature superconducting magnet, a high temperature superconducting magnet, or any magnet capable of generating a large magnetic field.
The propulsion levitation unit 4 may include linear motor stator coils and levitation coils/levitation plates according to one embodiment of the present invention.
For example, a sealing layer 6 may be disposed on the outer surface of the propulsion levitation unit 4 and the side walls and the upper surface of the track beam 3 in a fitting manner; alternatively, the sealing layer 6 may also be formed integrally with the propulsion levitation unit and then the integrated unit is mounted on the track beam to achieve the arrangement of the sealing layer 6 on the outer surface of the propulsion levitation unit 4 and the side walls and the upper surface of the track beam 3.
In other words, in any case, the sealing layer 6 is closely attached to the outer surface of the propulsion levitation unit 4 and the side walls and the upper surface of the track beam 3 to achieve sealing.
According to an embodiment of the present invention, the semi-enclosed pipe support halo 5 may have a shape satisfying the omega semi-enclosed shape of a high-speed magnetic levitation train.

And the fixing part is mainly connected to the track beam, so that the fixing is reliable. The magnetic field of the superconducting magnet is mainly in a direction perpendicular to the track beam stator coil. The semi-surrounding pipeline support ring 5 is far away from the superconducting magnet and is not opposite to a main magnetic field generated by the superconducting magnet, and eddy current loss generated on the ring is far smaller than that in the prior art.

Thus, the exemplary term "above … …" can include both an orientation of "above … …" and "below … …". The device may be otherwise variously oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
It should be noted that the terms "first", "second", and the like are used to define the components, and are only used for convenience of distinguishing the corresponding components, and the terms have no special meanings unless otherwise stated, and therefore, the scope of the present invention should not be construed as being limited.
