Description

Technical Field

[0001] The invention relates to the technical field of magnetic levitation tracks, and in particular to a superconducting magnetic levitation Mobius ring track and a construction method thereof. Background Art

[0002] Magnetic levitation technology is a technology that uses magnetic fields to achieve contactless suspension of objects. Its core lies in achieving stable suspension and movement by controlling the magnetic field. At present, most superconducting magnetic levitation track structures are flexible tracks, which need to be manually twisted 180 degrees, bent 360 degrees, and glued end to end. During the twisting and bending process, the track has a certain strength, so the installation is cumbersome and difficult. In addition, since the track is a flexible track, the shape after fixed twisting during the plastic process cannot achieve the expected effect, and the ornamental effect is not high. A small number of superconducting magnetic levitation Möbius ring tracks are machine-made, but there are certain requirements for the machine. A large amount of material and time will be consumed during the processing, and the processing cost is high.

[0003] The existing invention patent with publication number CN106297503A discloses a topological track superconducting magnetic levitation device, including a topological track, including: a supporting body, having a closed ring shape formed by connecting the two ends of the slender structure after rotating the slender structure around its long axis by a predetermined angle, the slender structure has a rotationally symmetrical cross-sectional shape, and has N rotationally symmetrical surfaces, the rotation angle is 360 / N, N is a positive integer greater than or equal to 3, the predetermined angle is n×360 / N degrees, n is a positive integer greater than or equal to 1; and the first to Nth magnetic components are respectively arranged on the N rotationally symmetrical surfaces of the slender structure, and the first to Nth magnetic components are also rotationally symmetrically arranged. Although the topological track superconducting magnetic levitation device realizes the topological track through the overall torsion of the slender structure with a regular polygonal cross-section, its essence is still limited by the traditional geometric configuration, and there are problems such as high processing difficulty and uncontrollable magnetic field distribution.

[0009] Step 4: Uniformly adsorb permanent magnetic blocks on the surfaces of each straight torsion track and arc-shaped rotary track, and adjust the distance between two adjacent permanent magnets so that the magnetic pole directions of all permanent magnets are the same and the magnetization direction is perpendicular to the tangent direction of the corresponding track surface.

[0014] Optionally, when N is 0, α is 180°; when M is 8, the torsion angle of a single straight torsion track is 22.5 degrees, and the rotation angle of a single arc-shaped rotary track is 45 degrees.

[0039] See also Figure 1-6 The present invention provides a schematic diagram of a superconducting magnetic levitation Möbius ring track, wherein: Figure 1 As shown, the track is a closed-loop track body, and the closed-loop track body includes M straight-line twisted tracks 1 and M circular arc rotary tracks 2 that are alternately connected. The structures of the straight-line twisted tracks and the circular arc rotary tracks are shown in FIG. Figures 2-3 As shown, each adjacent straight torsion track 1 is fixedly connected to the circular arc rotary track 2, preferably by screws or flanges.

[0040] Furthermore, if Figures 4-5As shown, at both ends of each linear torsion track 1, there are a first linear extension connection unit 11 and a second linear extension connection unit 12 located on different planes. At both ends of each arc rotary track 2, there are also a first curve extension connection unit 21 and a second curve extension connection unit 22 located on different planes. In the closed-loop track body, the first linear extension connection unit 11 is connected to the second curve extension connection unit 22, and the second linear extension connection unit 12 is connected to the first curve extension connection unit 21. In a single independent segment, it can be composed of the connection of a single first linear extension connection unit 11 and a second curve extension connection unit 22, or it can be composed of the connection of a single second linear extension connection unit 12 and a first curve extension connection unit 21. Preferably, through holes corresponding to each other are uniformly arranged on each of the first linear extension connection unit 11, the second linear extension connection unit 12, the first curve extension connection unit 21, and the second curve extension connection unit 22.

[0041] Further, the torsion angle of each linear torsion track 1 is α / M, and the rotation angle of each arc rotary track 2 is 360° / M, where α = 180°×(2N + 1), N is an integer ≥ 0, and M is an integer ≥ 2. It can be seen that the torsion angle of each linear torsion track 1 and the rotation angle of each arc rotary track 2 can be adjusted, as long as it is ensured that the sum of the torsion angles of M linear torsion tracks 1 is equal to 180*(2N + 1) degrees, and the sum of the rotation angles of M arc rotary tracks 2 is equal to 360 degrees. Preferably, α = 180°×(2N + 1), N is an integer ≥ 0, and M is an integer ≥ 3.

[0042] Further, α / M is an acute angle.

[0043] Further, when N is 0, α is 180°, and M is 8, the torsion angle of a single linear torsion track is 22.5 degrees, and the specific structure is as Figure 6 shown; the rotation angle of a single arc rotary track is 45 degrees.

[0044] Further, a permanent magnet array layer is also provided on the track surface. The permanent magnet array layer is composed of a plurality of permanent magnets with the same polarity magnetized perpendicularly along the tangent direction of the track. Then, by adsorbing permanent magnet blocks in sequence according to a rule, a superconducting magnetic levitation Möbius ring track can be formed. Preferably, on the surface of the linear torsion track 1, adjacent permanent magnets are arranged at equal intervals along the track extension direction, and on the surface of the arc rotary track 2, adjacent permanent magnets are distributed at equal angles along the circumferential direction.

[0045] Further, each linear torsion track 1 is a prismatic structure and is arranged in central symmetry.

[0046] Further, each arc rotary track 2 is a conical surface structure.

[0047] Furthermore, the permanent magnet array layer is fixed by an adhesive or a mechanical buckle, and the magnetization direction is perpendicular to the tangent of the track.

[0048] Furthermore, to better illustrate the structure of the present invention, the following is described by a specific construction method. The construction method of the superconducting magnetic levitation Möbius ring track includes the following steps:

[0049] Step 1: Twist each of the M first rectangular tracks by an angle of α / M along the length direction to obtain M straight twisted tracks 1, as Figure 2 shown, where α = 180°×(2N + 1), N is an integer ≥ 0, M is an integer ≥ 2. Preferably, the straight twisted track 1 has a prismatic structure.

[0050] Step 2: Bend each of the M second rectangular tracks by a preset rotation angle along the length direction to obtain M arc-rotated tracks 2, as Figure 3 shown, where the preset rotation angle is 360° / M, and each arc-rotated track has a conical structure, and its central angle is equal to the preset rotation angle of each arc-rotated track.

[0051] Step 3: Connect each straight twisted track 1 to the adjacent arc-rotated track 2 in sequence, so that the starting angles of the arc-rotated tracks 2 increase successively by α / M, that is, through the connection of "twisted track + rotated track + twisted track + rotated track +...", finally obtaining a closed-loop track body. Among them, the straight twisted track provides the twisting angle for the Möbius ring, and the arc-rotated track provides the rotation angle for the Möbius ring, and finally obtaining a Möbius ring. In addition, during the actual connection process, a first straight extended connection unit 11 of a straight twisted track 1 can be first connected to a second curved extended connection unit 22 of an arc-rotated track 2 to form 1 independent segment, and then the second straight extended connection unit 12 in the independent segment can be connected to the first curved extended connection unit 21 in another independent segment, or a second straight extended connection unit 12 of a straight twisted track 1 can be connected to the first curved extended connection unit 21 of an arc-rotated track 2 to form 1 independent segment, and then the first straight extended connection unit 11 in the independent segment can be connected to the second curved extended connection unit 22 in another independent segment. Preferably, the first straight extended connection unit 11 and the second curved extended connection unit 22 are connected by screws, and the second straight extended connection unit 12 and the first curved extended connection unit 21 are connected by screws, and the cross-sections of the connection units are basically the same.

[0052] Step 4: Uniformly adsorb permanent magnetic blocks on the surfaces of each straight-line torsion track 1 and arc rotary track 2, and adjust the spacing between two adjacent permanent magnets so that the magnetic pole directions of all permanent magnets are the same and the magnetization direction is perpendicular to the tangent direction of the corresponding track surface. Preferably, on the surface of the straight-line torsion track 1, adjacent permanent magnets are arranged at equal intervals along the track extension direction, and on the surface of the arc rotary track 2, adjacent permanent magnets are distributed at equal angles along the circumferential direction, forming a periodic arrangement as a whole. The finally obtained superconducting magnetic levitation Möbius ring track is a regular polygon (M-sided polygon) structure composed of a straight-line torsion track and an arc rotary track.

[0053] The construction of the superconducting magnetic levitation Möbius ring track of the present invention is achieved by separately processing a preset number of straight-line torsion tracks and arc rotary tracks in sequence, and through alternating assembly, finally obtaining the target superconducting magnetic levitation Möbius ring track, thereby greatly reducing the processing difficulty of the track. Among them, by adopting segmented processing, the dimensional accuracy of each section of the track can be strictly controlled, and the shape is regular and controllable, simplifying the processing difficulty. And during the processing, each section of the track is processed separately, which requires low equipment requirements, and is also easy to install and maintain, effectively reducing the processing difficulty and also reducing the cost investment.
