Description

Technical Field

[0001] The present invention relates to the field of deep space exploration technology, and in particular to a flexible superconducting magnetic levitation propulsion device for use in the shadow area of ​​the moon. Background Art

[0002] In the new era of lunar exploration activities, it is necessary to carry out relevant equipment research and development for engineering implementation. Among them, mobile carriers are the core equipment to support large-scale lunar exploration, cargo transportation and other operations. At present, various forms of walking mechanisms have been proposed, including wheeled, tracked, legged, wheel-leg composite, and wheel-track composite. The above walking mechanisms all need to be in continuous or discontinuous dynamic contact with the soft lunar soil. During the walking process, the lunar soil will be compressed and squeezed out, resulting in energy loss, slow walking speed and low efficiency. In addition, tiny lunar dust entering the kinematic pairs such as rotating joints will cause wear and stagnation, which seriously threatens the survivability of mobile carriers. It is worth noting that the low temperature on the lunar surface can reach minus 180°C, and the temperature in the permanent shadow area can be as low as about minus 248°C. Traditional electromechanical components will face unprecedented tests. It can be seen that traditional walking mechanisms still have certain deficiencies in the application of lunar engineering. In order to avoid dynamic contact between moving parts and between the walking mechanism and the road surface, some suspension propulsion methods have been proposed, but they all have varying degrees of deficiencies, as recorded in the following public patents:

[0003] Chinese patent CN 1191183C (superconducting magnetic levitation transportation system) provides an energy-saving transportation system using the high-temperature superconducting magnetic levitation effect. The non-contact suspension state of the transport vehicle is used to reduce friction losses. The vacuum or negative pressure channel can significantly reduce air drag losses. Potential energy provides almost all of the operating power, but it does not mention how to adapt to unknown unpaved surfaces.

[0004] Chinese patent CN 103661420B (air-floating train system) provides an air-floating train system. Under the action of traction, the air-floating train uses an air film to run on a guide rail or a flat and solid ground. The system structure is simple and compact, and can achieve guided traction of the vehicle and smooth passage through curved tracks. However, it does not mention how to achieve air-floating traction under conditions where there is no air source or the air source is limited (such as the surface of the moon).

[0005] Chinese patent CN 106160581B (magnetic levitation system based on high-temperature superconducting film and coated conductor thereof) provides the use of high-temperature superconducting film and coated conductor thereof to realize the anti-magnetic flux performance of superconductors, and can realize a large-area, high-visibility levitation effect on permanent magnets. The invented high-temperature superconducting magnetic levitation system has the advantages of low weight, large design area, simple materials and low cost. However, the article does not mention how to maintain the levitation stability of superconducting magnets.

[0006] In summary, the above-mentioned patents fail to solve the problem of achieving propulsion function by non-dynamic contact and stable suspension under environmental conditions such as rugged and soft lunar surface, high vacuum, and extremely low temperature. Summary of the invention

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other. In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0035] like Figure 1 , Figure 8 As shown, this embodiment provides a flexible superconducting magnetic levitation propulsion device for the shadow area of ​​the moon, including a flexible stator 1 and a flexible mover 2. The flexible stator 1 is composed of a plurality of stator segments 11 connected together, such as Figure 7 As shown, the flexible mover 2 includes the first mover segment 21, the second mover segment 23, and the third mover segment 25. The mover segments are connected by the first flexible belt 22 and the second flexible belt 24. The flexible mover 2 is suspended on the flexible stator 1 by the magnetic repulsion between the superconducting magnet module and the single-peak permanent magnet module. The electromagnetic force between the driving module 111 and the permanent magnet array module 211 is used to drive the flexible mover 2 to move longitudinally (x direction) and transversely (y direction). The flexible stator 1 can be laid on the rugged and soft lunar surface, and the flexible mover 2 can be passively bent under the action of gravity to match the curvature of the flexible stator 1. The single-peak permanent magnet module includes the first single-peak permanent magnet module 212 and the second single-peak permanent magnet module 213.

[0036] In this embodiment, the flexible stator 1 is composed of a plurality of stator segments 11 connected together, and the stator segment 11 includes a driving module 111, a first superconducting magnet module 112, and a second superconducting magnet module 113. The first superconducting magnet module 112, the second superconducting magnet module 113 are fixedly connected to the driving module 111, and all three can be bent. When the stator segment 11 is laid, it can fit the rugged lunar surface under the action of its own weight.

[0037] like Figure 2As shown, the driving module 111 includes a multi-layer flexible circuit board 1111, a first rigid circuit board 1112, a second rigid circuit board 1113, a snap plug 1114, an electrical connector plug 1115, a snap socket 1116, an electrical connector socket 1117, a driving circuit 1118, a control circuit 1119, a first tunnel magnetoresistive sensor 111-10, a second tunnel magnetoresistive sensor 111-11, a third tunnel magnetoresistive sensor 111-12, a fourth tunnel magnetoresistive sensor 111-13, a fifth tunnel magnetoresistive sensor 111-14, a sixth tunnel magnetoresistive sensor 111-15, a seventh tunnel magnetoresistive sensor 111-16, and an eighth tunnel magnetoresistive sensor 111-17. The magnetic field data sensed by the tunnel magnetoresistive sensor is transmitted to the control circuit 1119. After processing and calculation, the control circuit 1119 outputs a control signal, and the multi-layer flexible circuit board 1111 is energized through the driving circuit 1118, thereby controlling the flexible mover 2. The snap plugs 1114 and snap sockets 1116 of different stator segments are interconnected to ensure a firm mechanical connection between the stator segments. The electrical connector sockets 1117 and electrical connector plugs 1115 of different stator segments are interconnected to ensure reliable transmission of power and signal electricity. The multi-layer flexible circuit board 1111, the rigid circuit board 1112 and the rigid circuit board 1113 are manufactured in an integrated manner. The snap plugs 1114 and the electrical connector plugs 1115 are mounted on the rigid circuit board 1112, the snap sockets 1116 and the electrical connector sockets 1117 are mounted on the rigid circuit board 1113, and the drive circuits 1118 and the control circuits 1119 are mounted on the rigid circuit board 1112. The tunnel magnetoresistance sensor is mounted on the multi-layer flexible circuit board 1111.

[0038] like Figure 3 , Figure 4 , Figure 5 As shown, the multi-layer flexible circuit board 1111 is sequentially the first A1 from top to bottom. 2 O 3 layer 11111, first covering layer 11112, first copper foil layer 11113, first substrate 11114, second copper foil layer 11115, second covering layer 11116, third copper foil layer 11117, second substrate 11118, fourth copper foil layer 11119, third covering layer 111110, second Al 2 O 3Layers 111111 are laminated in sequence. A longitudinal winding A phase coil 111131 is buried in the first copper foil layer 11113, a longitudinal winding B phase coil 111151 is buried in the second copper foil layer 11115, a transverse winding A phase coil 111171 is buried in the third copper foil layer 11117, and a transverse winding B phase coil 111191 is buried in the fourth copper foil layer 11119. Passing alternating current with a phase difference of 90° through the longitudinal winding A phase coil 111131 and the longitudinal winding B phase coil 111151 can make the flexible mover 2 move longitudinally, and passing alternating current with a phase difference of 90° through the transverse winding A phase coil 111171 and the transverse winding B phase coil 111191 can make the flexible mover 2 move smoothly in the transverse direction. 2 O 3 The layer can enhance wear resistance and reduce friction coefficient.

[0039] like Figure 6 As shown, the first superconducting magnet module 112 includes the third Al 2 O 3 layer 1121, a first high temperature superconducting tape 1122, a second high temperature superconducting tape 1123, a third high temperature superconducting tape 1124, a fourth high temperature superconducting tape 1125, and a fourth Al 2 O 3 Layer 1126, each layer is laminated in sequence, the high temperature superconducting tape is a thin plate with a certain width, Al 2 O 3 The layer plays a role in enhancing wear resistance and reducing friction coefficient. In the low temperature environment of the lunar shadow area, the first superconducting magnet module 112 composed of stacked high-temperature superconducting tapes can capture a large amount of magnetic flux under the action of pulse magnetization, generating a stable magnetic field that does not decay over time, and the magnetic field polarity is opposite to that of the permanent magnet, thereby generating a suspension force. The second superconducting magnet module 113 has the same structure and working principle as the first superconducting magnet module 112.

[0040] like Figure 7As shown, the flexible mover 2 is connected in sequence by the first mover segment 21, the first flexible belt 22, the second mover segment 23, the second flexible belt 24, and the third mover segment 25, wherein the mover segment is rigid, the flexible belt is bendable, and the flexible mover 2 can be passively bent under the action of gravity by relying on the first flexible belt 22 and the second flexible belt 24. The first mover segment 21, the second mover segment 23, and the third mover segment 25 all include a permanent magnet array module 211, a first single-peak permanent magnet module 212, a second single-peak permanent magnet module 213, and a rigid substrate 214. The permanent magnet array module 211, the first single-peak permanent magnet module 212, and the second single-peak permanent magnet module 213 are all vertically fixedly connected to the rigid substrate 214, and the rigid substrate 214 is longitudinally (x) fixedly connected to the first flexible belt 22. The other structures of the flexible mover 2 are connected in the same way. The permanent magnet array module 211 is composed of the first permanent magnet 2111 arranged in sequence with opposite magnetic field polarities. The first single-peak permanent magnet module 212 is composed of the first magnet yoke 2121, the second permanent magnet 2122, the second magnet yoke 2123, the third permanent magnet 2124, and the third magnet yoke 2125. The single-peak permanent magnet module relies on the permanent magnet to generate a single-peak stable magnetic field, and the polarity is opposite to the magnetic field of the superconducting magnet module below it. The two interact with each other to generate repulsion, and then generate suspension force.

[0041] The specific working principle of this embodiment is as follows: the superconducting state of the superconducting magnet module is established by using the low temperature environment of the shadow area of ​​the moon, and the superconducting magnet module is excited by pulse magnetization to capture the magnetic flux of the superconducting magnet module, forming a stable magnetic field that does not decay over time. The single-peak permanent magnet module is arranged above the superconducting magnet module, and the magnetic field polarity is opposite to that of the superconducting magnet module. In this way, the repulsive force between the magnetic fields is used to suspend the flexible mover 2 above the flexible stator 1. The stator segments of the flexible stator 1 are connected and locked by the buckle socket and the buckle plug to form a firm mechanical connection, and the electrical connector socket and the electrical connector plug are connected and locked to establish reliable power and signal transmission.

[0042] A plurality of tunnel magnetoresistive sensors jointly sense the magnetic field information of the flexible mover 2 and transmit it to the control circuit 1119 for processing and calculation. The control drive circuit 1118 passes appropriate current through the longitudinal winding A phase coil 111131 and the longitudinal winding B phase coil 111151, and realizes the longitudinal (x) movement of the flexible mover 2 through the coupling effect of the coil magnetic field and the magnetic field of the permanent magnet array module. The control drive circuit 1118 passes appropriate current through the transverse winding A phase coil 111171 and the transverse winding B phase coil 111191, and realizes the transverse (y) movement of the flexible mover 2 through the coupling effect of the coil magnetic field and the magnetic field of the permanent magnet array module. Since the suspension force generated by the superconducting magnet module is not stable in the transverse direction, the current control of the transverse winding A phase coil 111171 and the transverse winding B phase coil can also assist in realizing stable superconducting magnetic suspension. The multi-layer flexible circuit board 1111 and the first superconducting magnet module 112 and the second superconducting magnet module 113 of the flexible stator 1 are all bendable, so the flexible stator 1 can be laid in a close fit with the rugged and soft lunar surface. The movable segments of the flexible mover 2 are connected by the first flexible belt 22 and the second flexible belt 24, so the flexible mover 2 can be passively bent under the action of gravity to match the curvature of the flexible stator 1. The flexible mover 2 has no contact and friction with the flexible stator 1, and the flexible stator 1 is in static contact with the lunar surface. Therefore, the propulsion device avoids the energy loss caused by the compression and extrusion of the lunar soil by the walking mechanism, improves the propulsion efficiency, and at the same time avoids the wear and stagnation of the kinematic pair caused by the lunar soil, thereby improving the service life.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
