Description
Technical Field
The invention relates to the field of rail transit operation, in particular to a vacuum pipeline for the operation of a maglev train.
Background
Magnetic levitation transport is a transport mode that is accomplished by eliminating mechanical friction between a track and a transport or vehicle by generating a levitation force through magnetic forces between the transport or vehicle and the track. However, when the transportation speed of the magnetic levitation transportation is increased, the loss is increased again due to the increase of the air resistance, and thus the magnetic levitation transportation is limited. In order to meet the requirement of improving the transportation speed and simultaneously overcome the air resistance, the energy consumption of a transmission or carrying tool has to be increased, and the difficulty is promoted for the development and wide application of magnetic levitation transportation.
In the prior art, a vacuum tunnel is used for providing a transmission or carrying channel for a magnetic-levitation train, air resistance is greatly reduced, and high-speed and low-consumption running is realized. However, the bottom of the train is still coated outside the magnetic track, and the weight of the train is completely borne below the magnetic suspension vacuum pipeline, so that the construction cost is extremely high, the construction amount is extremely large, the implementation is extremely difficult, and the maximum running speed of the magnetic suspension train is still limited.
In the prior art, an external thin-wall vacuum pipeline magnetic suspension traffic system of a power system is also provided, and a vacuum pipeline with a smaller thin wall thickness is adopted, and a linear motor coil, a track magnetic suspension mechanism and other communication, detection and control equipment are arranged outside the pipeline to provide running power, suspension force and control force for vehicles in the pipeline under the state that a thin wall is isolated. Therefore, the installation construction of the linear motor stator and the suspension mechanism can be conveniently carried out outside the pipeline; the daily maintenance in the operation process is also finished outside the pipeline; the heat dissipation of an electromechanical system is facilitated, and the heat accumulation in the vacuum pipeline is avoided; the space in the pipeline is not occupied; the construction, maintenance and system operation costs of the vacuum pipeline high-speed magnetic levitation transportation can be reduced.
Although the above schemes can reduce or even eliminate the action of air resistance to improve the running speed of magnetic levitation transportation, the magnetic levitation system is basically only directly applied to a vacuum pipeline or a structural form that a train track is arranged in the vacuum pipeline. This design, however, has the following problems:
1. the interaction of the suspension electromagnet and the long stator linear motor of the magnetic suspension traffic generates a suspension electromagnetic field and a traction electromagnetic field to realize decoupling, but the suspension electromagnet and the long stator linear motor are in a space at a physical position, so that the control complexity is increased;
2. the guiding electromagnet is also positioned in the same physical position space with the suspension electromagnetic field and the traction electromagnetic field, so that the problem of mutual interference of the magnetic fields is easily caused;
3. because suspension and traction guiding are integrated in an integrated space, the whole system is complex in structure and high in manufacturing and processing cost.
In order to solve the above problems, the present invention aims to provide a vacuum pipeline for running a maglev train and a maglev train capable of running in the vacuum pipeline.

The invention is described in detail below with reference to the figures and specific embodiments. It is noted that the aspects described below in connection with the figures and the specific embodiments are only exemplary and should not be construed as imposing any limitation on the scope of the present invention.
The vacuum pipeline magnetic suspension traffic is generally composed of a vacuum pipeline, a magnetic suspension vehicle, a linear motor and an operation control device. The vehicle-mounted components associated with the linear motor and the vehicle-mounted equipment associated with the suspension system must be mounted on the vehicle, and the power equipment fixed to the track or the pipeline can be placed either inside the pipeline or outside the pipeline. The invention aims to separately arrange a suspension system, a guide system and a propulsion system for controlling the running of the magnetic suspension vehicle, thereby completing the independent control of the suspension system, the guide system and the propulsion system and simplifying the running control process of the vacuum pipeline magnetic suspension traffic.
According to one aspect of the present invention, a vacuum conduit is provided for providing a space for a maglev train to travel. According to another aspect of the invention, corresponding to the vacuum pipeline, a magnetic suspension train capable of running in the vacuum pipeline is also provided.
In one embodiment, the vacuum conduit includes a conduit wall 101 and associated equipment mounted to the conduit wall for supporting the operation of a magnetic levitation train.
Fig. 1 shows a cross section of the vacuum pipeline perpendicular to the extending direction of the vacuum pipeline, and as shown in fig. 1, the cross section of a pipeline wall surface 101 of the vacuum pipeline is in a polygonal structure with bilateral symmetry, and the vacuum inside the vacuum pipeline is used for the passage of a magnetic suspension train.
It is understood that the vacuum pipeline is not limited to an environment with absolute vacuum, but a pipeline with vacuum degree meeting the running condition of the magnetic suspension train. Preferably, the vacuum degree in the pipe wall 101 is 0.3-0.5.
The associated equipment mounted on the pipeline wall 101 includes a suspension system steel plate 102, a guidance system steel plate 103, and a propulsion system primary side 104. The levitation system steel plate 102, the guidance system steel plate 103 and the propulsion system primary side 104 are respectively installed at different positions of the pipeline wall 101 to physically separate the levitation system, the guidance system and the propulsion system of the maglev train.
Although FIG. 1 shows the suspension system steel plate 102, the guidance system steel plate 103, and the propulsion system primary side 104 all disposed at different locations on the exterior of the pipe wall 101, those skilled in the art will appreciate that different locations of the pipe wall 101 may include the interior or exterior of the pipe wall 101, i.e., the suspension system steel plate 102, the guidance system steel plate 103, and the propulsion system primary side 104 may also be disposed at different locations within the pipe wall 101.
In contrast, a magnetic levitation train corresponding to the vacuum line shown in fig. 1 may include a car body 201, the cross-section of the car body 201 being as shown in fig. 1.
The vehicle body 201 is provided with a levitation system excitation 202, a guidance system excitation 203, and a propulsion system secondary 204, which are provided at appropriate positions on the vehicle body 201. Specifically, the arrangement positions of the levitation system exciter 202, the guidance system exciter 203, and the propulsion system secondary 204 on the vehicle body 201 need to satisfy: when the magnetic levitation train runs in the vacuum pipeline, the levitation system excitation 202, the propulsion system secondary 204 and the guidance system excitation 203 arranged on the train body 201 are respectively opposite to the levitation system steel plate 102, the guidance system steel plate 103 and the propulsion system primary side 104 arranged on the pipeline wall surface 201 of the vacuum pipeline.
Specifically, levitation system excitation 202 and guidance system excitation 203 may specifically refer to a levitation system excitation electromagnet and a guidance system excitation electromagnet for providing a levitation magnetic field or a guidance magnetic field.
Preferably, the cross-sectional shape of the car body 201 may be similar to the cross-sectional shape of the duct wall 101 of the vacuum duct so that the levitation system excitation 202, the guidance system excitation 203, and the propulsion system secondary 204 are disposed in one-to-one correspondence with the levitation system steel plate 102, the guidance system steel plate 103, and the propulsion system primary side 104, respectively.
The suspension system comprises a suspension system steel plate 102 arranged on the pipeline wall surface 101 and a suspension system excitation 202 arranged on the train body 201, and the suspension system can provide suspension force and a stable suspension air gap for the running of the magnetic-levitation train so as to ensure the safe and stable running of the magnetic-levitation train in the vacuum pipeline and avoid the friction resistance between the magnetic-levitation train and the vacuum pipeline.
The suspension system can adopt a repulsion suspension system or a suction suspension system or a combination thereof.
When the repulsive suspension system is adopted, the suspension system steel plate 102 arranged on the vacuum wall surface 101 of the vacuum pipeline is at least arranged at the bottom of the vacuum wall surface 101, the suspension system excitation 202 is correspondingly arranged at least at the bottom of the magnetic suspension train, and the suspension system can provide a repulsive force opposite to the gravity line of the magnetic suspension train. Fig. 1 shows a schematic cross-sectional view of an octagonal vacuum duct and an adapted octagonal maglev train, and the various orientations of the octagonal cross-section are numbered, wherein the bottom of the vacuum wall 101 may correspond to position 1 on the vacuum wall and the bottom of the maglev train may correspond to position 1 on the vehicle body 201. It should be noted that the position numbers are only used for defining the relative position of the setting position on the physical space, and are not used for defining the specific position corresponding to the vacuum wall surface 101 or the vehicle body 201, for example, the position No. 1 on the vacuum wall surface 101 may also include the corresponding position set inside the vacuum wall surface 101.
Furthermore, to prevent the top of the maglev train from contacting the top of the vacuum pipe, a suspension system steel plate 102 may be additionally disposed on the top (corresponding to position 2) of the vacuum wall 101. Correspondingly, a suspension system excitation 202 is additionally arranged at the top of the magnetic-levitation train 201, so that a repulsion type suspension system is formed at the top of the vacuum pipeline magnetic-levitation traffic, the repulsion type suspension system is only used for preventing the magnetic-levitation train from contacting with the vacuum pipeline without obstructing the suspension condition of the magnetic-levitation train, and the generated repulsion can be smaller than that generated by the suspension system arranged at the bottom.
Alternatively, when a suction levitation system is used, the levitation system steel plate 102 disposed on the vacuum wall 101 of the vacuum pipeline is at least disposed on the top of the vacuum wall 101, and the levitation system exciter 202 is correspondingly disposed on at least the top of the maglev train, so that the levitation system can provide a suction force opposite to the gravity line of the maglev train. As shown in fig. 1, the top of the vacuum wall 101 may correspond to position No. 2 on the vacuum wall, and the top of the maglev train may correspond to position No. 2 on the car body 201. It should be noted that the position numbers are only used for defining the relative position of the setting position on the physical space, and are not used for defining the specific position corresponding to the vacuum wall surface 101 or the vehicle body 201, for example, the position No. 2 on the vacuum wall surface 101 may also include the corresponding position set inside the vacuum wall surface 101.
Furthermore, to prevent the bottom of the maglev train from contacting the bottom of the vacuum pipe, a suspension system steel plate 102 may be additionally disposed at the bottom (corresponding to position No. 1) of the vacuum wall 101. Correspondingly, a suspension system excitation 202 is additionally arranged at the bottom of the maglev train 201, so that a suction type suspension system is formed at the bottom of the vacuum pipeline maglev traffic, the suction type suspension system is only used for preventing the maglev train from contacting with a vacuum pipeline without obstructing the suspension condition of the maglev train, and the generated suction force can be smaller than that generated by the suspension system arranged at the top.
Alternatively, when the levitation system of the vacuum pipeline magnetic levitation transportation is configured by combining the suction levitation system and the repulsion levitation system, the suction levitation system may be configured on the top of the magnetic levitation train and the top of the vacuum pipeline to form a suction force opposite to the gravity line of the magnetic levitation train, and the repulsion levitation system may be configured on the bottom of the magnetic levitation train and the bottom of the vacuum pipeline to form a repulsion force opposite to the gravity line of the magnetic levitation train, and the suction levitation system and the repulsion levitation system support the vehicle body 201 to be levitated in the vacuum pipeline.
Furthermore, the number of the suspension systems arranged on the vacuum pipeline magnetic suspension traffic can be properly designed redundantly so as to prevent the suspension system faults from influencing the operation of the vacuum pipeline magnetic suspension traffic.
Furthermore, the excitation of the levitation system arranged on the maglev train can adopt electric excitation, mixed excitation, superconducting excitation or various excitations of novel materials or technologies capable of generating constant magnetic field force. It can be understood that the levitation height of the maglev train is determined by the levitation magnetic field of the levitation system and the condition of the maglev train, and the maglev train can be controlled at a certain precise position within the levitation height range by controlling the current passing through the excitation of the levitation system within the range of the relative levitation height, so that the maglev train can run at a relatively stable levitation height.
The guide system steel plate 103 arranged on the pipeline wall surface 101 and the guide system arranged on the train body 201 form a guide system of the vacuum pipeline magnetic suspension traffic by excitation, and the guide system can provide guide force for the running of a magnetic suspension train so as to support the magnetic suspension train to turn along the trend of the vacuum pipeline.
The guidance system and the suspension system have similar principles, and a repulsive guidance system or a suction guidance system can be adopted. It will be appreciated that the vacuum line maglev vehicle needs to include at least a left-hand guidance system and a right-hand guidance system to provide a left-hand guidance force and a right-hand guidance force, respectively, for the operation of the maglev train. Preferably, the steel plates 103 are disposed on the left and right portions of the duct wall surface 101 of the vacuum duct, i.e., the 4 th position shown in fig. 1, so that the points of action of the left guide force generated by the left guide system and the right guide force generated by the right guide system can be located on the same plane as the center of gravity of the cross section of the vehicle body 201 as much as possible.
When a repulsive guidance system is adopted, the left and right parts of the pipe wall surface 101 of the vacuum pipe, i.e. the position 4 shown in fig. 1, are provided with guidance system steel plates, and the left and right parts of the train body 201 of the magnetic-levitation train, i.e. the position 4 shown in fig. 1, are provided with corresponding guidance system excitation. The guiding system excitation arranged on the left part of the train body 201 of the maglev train and the guiding system steel plate arranged on the left part of the pipeline wall surface 101 of the vacuum pipeline form a right-direction guiding system to provide right-direction guiding force for the maglev train. The guiding system excitation arranged on the right part of the train body 201 of the maglev train and the guiding system steel plate arranged on the right part of the pipeline wall surface 101 of the vacuum pipeline form a left-direction guiding system to provide left-direction guiding force for the maglev train.
When a suction type guiding system is adopted, the left part and the right part of the pipeline wall surface 101 of the vacuum pipeline, namely the No. 4 position shown in figure 1, are provided with guiding system steel plates, and the left part and the right part of the train body 201 of the magnetic suspension train, namely the No. 4 position shown in figure 1, are provided with corresponding guiding system excitation. The left guide system is formed by a guide system excitation arranged on the left part of the train body 201 of the maglev train and a guide system steel plate arranged on the left part of the pipeline wall surface 101 of the vacuum pipeline, so as to provide left guide force for the maglev train. The guiding system excitation arranged on the right part of the train body 201 of the maglev train and the guiding system steel plate arranged on the right part of the pipeline wall surface 101 of the vacuum pipeline form a right-direction guiding system to provide right-direction guiding force for the maglev train.
Furthermore, the number of the guiding systems arranged on the vacuum pipeline magnetic suspension traffic can be properly designed redundantly, so that the influence of the fault of the guiding systems on the operation of the vacuum pipeline magnetic suspension traffic is prevented.
Furthermore, the excitation of the guidance system arranged on the magnetic-levitation train can adopt various excitations of electric excitation, mixed excitation, superconducting excitation or other novel materials or technologies capable of generating constant magnetic field force.
Preferably, the suspension system steel panels or the guidance system steel panels may be laid along each side of the pipe wall 101, for example, suspension system steel panels disposed at the upper and lower portions of the octagonal pipe wall 101 shown in fig. 1 may be laid horizontally along the upper or lower plane of the octagon; the steel guide system plates provided to the left and right of the octagonal pipe wall surface 101 shown in fig. 1 may be laid vertically along the left and right planes of the octagon. The terms "horizontal laying" and "vertical laying" are both relative to the lower plane of the octagon, i.e. the plane of travel of the magnetic levitation train.
It can be understood that after the devices required by the guidance system and the levitation system are arranged based on the characteristics of the guidance system and the levitation system, other positions on the pipe wall 101 of the vacuum pipe can be used for arranging the primary side of the propulsion system, and the secondary side of the propulsion system on the maglev train can be correspondingly arranged.
Taking the octagonal vacuum duct shown in fig. 1 as an example, when the suspension system steel plates are provided on the upper and lower portions of the duct wall 101 of the vacuum duct corresponding to the upper and lower planes of the octagon, and the guide system steel plates are provided on the left and right portions of the duct wall 101 corresponding to the left and right planes of the octagon, the other planes of the duct wall 101 may be used to provide the primary side of the propulsion system, as shown in any one of position 3 in fig. 1.
It can be understood that the propulsion system primary side 104 on the pipe wall 101 of the vacuum pipe and the propulsion system secondary side provided on the vehicle body 201 of the maglev train constitute a propulsion system of the vacuum pipe maglev transportation for providing a traction force for the maglev train.
The number of propulsion systems may be determined based on the maximum power demand and maximum tractive effort required by the magnetic levitation train. Preferably, the duct wall 101 of the vacuum duct is laid as much as possible on the primary side of the propulsion system, taking into account the fact that the magnitude of the tractive force required by different magnetic levitation trains may differ, while the magnetic levitation train may set the number of secondary sides of the propulsion system based on the magnitude of the actual tractive force it requires. Preferably, the dedicated vacuum line may also determine the number of primary sides of the propulsion system based on the maximum tractive effort required to operate the magnetic levitation train therein. Still further, the number of primary sides of the propulsion systems may also be determined based on the maximum tractive effort required to operate the magnetic-levitation train therein and the number of redundant propulsion systems required.
Further, the propulsion system of the vacuum pipeline magnetic suspension traffic can be realized by a long stator linear motor. The primary side of the propulsion system provided on the duct wall 101 of the vacuum duct may be a stator section of a long stator linear motor. The linear generator winding is embedded on the secondary side of the propulsion system arranged on the train body 201 of the maglev train, and when the train runs at high speed (usually at the speed of over 70 km/h), the high-order harmonic current is utilized to generate electricity for electrically supplying power to the vehicles at the high-speed section.
Preferably, the linear generator winding embedded at the secondary side of the propulsion system arranged on the train body 201 of the maglev train also has the function of a generator, and can supply power for the excitation of the suspension system and the excitation of the guidance system of the maglev train and the electric system of the train after rectification.
Preferably, the levitation system steel plate 102, the guidance system steel plate 103 and the propulsion system primary side 104 arranged on the pipeline wall surface 101 of the vacuum pipeline are all arranged outside the pipeline wall surface 101, and correspondingly, the levitation system excitation 202, the guidance system excitation 203 and the propulsion system secondary side 204 arranged on the maglev train are arranged inside the train body 201, so that the inner surface of the pipeline wall surface 101 and the outer surface of the maglev train are smooth, and the resistance between the vacuum pipeline and the maglev train is reduced.
Furthermore, although the present disclosure describes a vacuum pipe and a maglev train running in the vacuum pipe by taking the vacuum pipe with the octagonal cross section as an example, those skilled in the art will understand that the cross section of the vacuum pipe does not need to be strictly regular octagon, and the length of each side of the octagon can be correspondingly adjusted based on the number or size of the devices arranged on the octagon.
Furthermore, the cross section of the vacuum pipeline can also adopt other polygonal structures with bilateral symmetry. Preferably, a polygonal structure, such as a hexagon, etc., which is symmetrical left and right and symmetrical up and down, may be employed. The suspension system, the guidance system and the propulsion system isolation control scheme of vacuum pipeline traffic can be realized by isolating the physical positions of the suspension system, the guidance system and the propulsion system by those skilled in the art, and all the schemes belong to the protection scope of the invention.
The previous description is provided to enable any person skilled in the art to practice the various aspects described herein. It is to be understood that the scope of the invention is to be defined by the appended claims and not by the specific constructions and components of the embodiments illustrated above. Those skilled in the art can make various changes and modifications to the embodiments within the spirit and scope of the present invention, and these changes and modifications also fall within the scope of the present invention.
