The utility model provides a controllable rotatory magnetism repels type suspending device.
In an embodiment of the present invention, referring to fig. 1 to 3, the magnetic repulsion suspension apparatus 1 includes:
a base 10, wherein the base 10 is provided with a suspension module 110 and a rotation control assembly 120 arranged around the suspension module 110, and the suspension module 110 has magnetism in a working state; and
a suspension assembly 20 including a magnetic suspension 210 and a controlled body 230 disposed on the magnetic suspension 210, wherein the magnetic suspension 210 is located above the base 10, and a magnetic repulsion force generated between the magnetic suspension 210 and the suspension module 110 is balanced with a gravity of the suspension assembly 20, so that the suspension assembly 20 is suspended above the base 10; the controlled body 230 and the rotating control assembly 120 generate a magnetic force therebetween to drive the levitation assembly 20 to rotate.
Not generally, the suspension module 110 located on the base 10 has magnetism, and the suspension module 110 may be composed of a permanent magnet and an electromagnetic coil, wherein the permanent magnet may be made of a ferrite permanent magnet material, an alnico permanent magnet alloy material, an iron-chromium-cobalt permanent magnet alloy material, a samarium-cobalt (SmCo) permanent magnet material, a neodymium-iron-boron (NdFeB) permanent magnet material, or the like. When the magnetic repulsion generated between the magnetic suspension 210 and the suspension module 110 is balanced with the self-weight of the suspension assembly 20, the suspension assembly 20 can be suspended above the base 10. Since there is no contact between the suspension assembly 20 and the base 10, when the suspension assembly 20 is driven to rotate by an external force, once the external force is removed, the suspension assembly 20 only receives air resistance, and the suspension assembly 20 can maintain a rotating state for a long time, i.e. the suspension assembly 20 can rotate freely above the base 10.
In order to realize the rotation control of the suspension assembly 20, the controllable rotation magnetic repulsion type suspension device 1 modifies the base 10 and the suspension assembly 20 as follows: the base 10 is provided with a rotation control assembly 120 surrounding the suspension module 110, the magnetic suspension 210 is provided with a controlled body 230, the controlled body 230 has magnetism, the rotation control assembly 120 also has magnetism, the magnetism and the magnetic field intensity of the rotation control assembly 120 can be adjusted, and the controlled body 230 and the rotation control assembly 120 can generate mutually attractive or mutually repulsive magnetic force. Since the rotating control assemblies 120 are circumferentially arranged around the suspension module 110, the local magnetic fields on the rotating control assemblies 120 can be sequentially changed, so as to achieve the effect of controlling the rotation of the suspension assembly 20.
It can be understood that the magnetic suspension 210 can carry a certain weight of the to-be-suspended matter 240, that is, when the to-be-suspended matter 240 is placed on the magnetic suspension 210, the sum of the gravity of the to-be-suspended matter 240, the controlled body 230, and the magnetic suspension 210 is the total gravity of the suspension assembly 20, and at this time, the gravity of the suspension assembly 20 is balanced with the magnetic repulsion between the magnetic suspension 210 and the suspension module 110, so that the to-be-suspended matter 240 achieves a suspension effect; when the to-be-levitated object 240 is not placed on the magnetic levitation member 210, the gravity of the levitation assembly 20 includes only the sum of the gravity of the magnetic levitation member 210 and the controlled body 230, and at this time, the gravity of the levitation assembly 20 and the magnetic repulsive force between the magnetic levitation member 210 and the levitation module 110 are balanced.
The utility model discloses technical scheme adopts and adds spin control subassembly 120 on base 10, adds controlled body 230 on the magnetic suspension piece 210, through changing the local magnetic field on the spin control subassembly 120 in proper order for can produce the magnetic force of inter attraction or mutual repulsion between controlled body 230 and the spin control subassembly 120, thereby drive magnetic suspension piece 210 takes place to rotate relative base 10, and then reaches the controllable pivoted effect of control magnetic suspension piece 210.
Further, the rotation control assembly 120 includes a controller 123 and a plurality of control coils 121, the plurality of control coils 121 are respectively connected to the controller 123, the plurality of control coils 121 are distributed at intervals along the circumferential direction of the suspension module 110, and the control coils 121 are energized to generate a magnetic field to drive the controlled body 230 to rotate; the controller 123 is configured to control the energization state of the control coil 121, so that the control coil 121 drives the magnetic suspension 210 to rotate. When the control coil 121 is energized, a magnetic field is generated, and the controlled body 230 is magnetic, so that the controlled body 230 is influenced by the magnetic field of the control coil 121 and moves towards a direction close to the control coil 121 or away from the control coil 121, thereby forming a driving force for driving the levitation assembly 20 to rotate. The plurality of control coils 121 may be arranged in a uniformly distributed manner, or may be arranged in a non-uniformly distributed manner, which is not limited herein.
It is understood that the controller 123 may control the energization state of one or more control coils 121 adjacent to the controlled body 230, so as to force the corresponding controlled body 230 to move. The controller 123 sequentially adjusts the energization state of the control coil 121 in the circumferential direction, so as to realize the rotation of the controlled body 230 in the circumferential direction of the base 10. For example, when the controller 123 controls each control coil 121 to be energized for 1 second clockwise in the circumferential direction, magnetic attraction is generated between the controlled body 230 and the control coil 121, and the controlled body 230 rotates clockwise in the circumferential direction of the base 10; when the controller 123 controls the two control coils 121 to be energized for 1 second clockwise in the circumferential direction, magnetic attraction is generated between the controlled body 230 and the control coils 121, and the controlled body 230 rotates clockwise in the circumferential direction of the base 10. Preferably, the controller 123 may simultaneously control the energization states of the plurality of control coils 121 adjacent to the controlled object 230, so that the controlled object 230 and the plurality of control coils 121 simultaneously generate magnetic force, thereby more reliably driving the controlled object 230 to rotate.
Referring to fig. 1 to 3 in combination with fig. 4, in an embodiment of the present invention, the base 10 has a plurality of control coils 121 (including a coil a, a coil b, a coil c, a coil d, a coil i, a coil j, etc., as shown in fig. 3 and 4), the controlled body 230 is disposed on an outer peripheral side of the magnetic suspension 210, and the controlled body 230 itself has magnetism or can be energized to generate a magnetic field. The controller 123 can control the energization state of each control coil 121, that is, the controller 123 can input a control signal to the power supply switch S-a of the coil a, and can control the energization state and the energization time of the coil a; the controller 123 may input a control signal to the power supply switch S-b of the coil b, and may control the energization state and the energization time of the coil b; the controller 123 may input a control signal to the power supply switch S-c of the coil c, and may control the energization state and the energization time of the coil c; the controller 123 may input a control signal to the power supply switch S-d of the coil d, and may control the energization state and the energization time of the coil d; the controller 123 may input a control signal to the power supply switch S-j of the coil j, and may control the energization state and the energization time of the coil j. For example, as shown in fig. 3, when the controlled body 230 drives the magnetic suspension 210 to rotate clockwise, the controlled body 230 is sequentially electrified for a preset time (for example, 0.5 second or 1 second) to the control coils 121 such as the coil b, the coil c, and the coil d, and the controlled body 230 is sequentially subjected to the magnetic attraction of the control coils 121 such as the coil b, the coil c, and the coil d, and further drives the magnetic suspension 210 to rotate clockwise; when the controlled body 230 drives the magnetic suspension 210 to rotate in the counterclockwise direction, the controlled body 230 is sequentially electrified for a preset time (for example, 0.5 second or 1 second) to the control coils 121 such as the coil a, the coil j, the coil i, and the like, and the controlled body 230 is sequentially subjected to the magnetic attraction of the control coils 121 such as the coil a, the coil j, the coil i, and the like, so as to drive the magnetic suspension 210 to rotate in the counterclockwise direction.
Further, when the controller 123 controls the energization of the plurality of control coils 121 simultaneously, the input currents of the plurality of control coils 121 may be the same or different; specifically, when the input currents of the plurality of control coils 121 are different, the distance between the control coil 121 and the controlled body 230 is inversely proportional to the current value of the input current, that is, the input current value of the control coil 121 closest to the controlled body 230 is the smallest, and the input current value of the control coil 121 farthest from the controlled body 230 is the largest. In this way, by increasing the input current of the control coil 121 farthest from the subject, the magnetic force between the control coil 121 and the controlled object 230 can be increased, so as to compensate for the control coil 121 farther away, and ensure that sufficient magnetic force is generated between the controlled object 230 and the control coil 121 to drive the controlled object 230 to rotate.
Of course, in this embodiment, the controller 123 may also control the power supply device to supply a reverse current to the control coil 121, so that the control coil 121 generates an electromagnetic resistance that hinders the rotation of the magnetic suspension 210, thereby achieving the speed reduction and braking effects on the magnetic suspension 210; or the controller 123 controls the power supply device to apply a reverse current to the control coil 121, so that the controlled body 230 rotates in the reverse direction, i.e., drives the magnetic suspension 210 to rotate in the reverse direction. In this way, by controlling the energization state of the control coil 121 and the magnitude of the input current value, the effects of controllable rotation, acceleration, deceleration, rotation stop, and the like of the magnetic suspension 210 can be achieved.
The controller 123 may also control the energization state of one or more control coils 121 adjacent to the controlled body 230 when a reverse current is applied to the control coils 121, so that the controlled body 230 is forced to move. The controller 123 sequentially adjusts the energization state of the control coil 121 in the circumferential direction, so as to realize the rotation of the controlled body 230 in the circumferential direction of the base 10. Preferably, the controller 123 may simultaneously control the energization states of the plurality of control coils 121 adjacent to the controlled object 230, so that the controlled object 230 and the plurality of control coils 121 simultaneously generate magnetic force, thereby more reliably driving the controlled object 230 to rotate. When the controller 123 controls the plurality of control coils 121 to be energized simultaneously, the input currents of the plurality of control coils 121 may be the same or different; specifically, when the input currents of the plurality of control coils 121 are different, the distance between the control coil 121 and the controlled body 230 is inversely proportional to the current value of the input current, that is, the input current value of the control coil 121 closest to the controlled body 230 is the smallest, and the input current value of the control coil 121 farthest from the controlled body 230 is the largest. In this way, by increasing the input current of the control coil 121 farthest from the subject, the magnetic force between the control coil 121 and the controlled object 230 can be increased, so as to compensate for the control coil 121 farther away, and ensure that sufficient magnetic force is generated between the controlled object 230 and the control coil 121 to drive the controlled object 230 to rotate.

Further, the magnetic suspension 210 is further provided with a first position sensor 220, each control coil 121 is provided with a second position sensor 122 connected to the controller 123, and when the first position sensor 220 rotates past the adjacent second position sensor 122, the second position sensor 122 adjacent to the first position sensor 220 outputs a position signal to the controller 123. Through setting up first position sensor 220 and second position sensor 122, can detect the real-time rotational position of magnetic suspension 210, and then be convenient for realize the more accurate rotation control to magnetic suspension 210. The first position sensor 220 and the second position sensor 122 may be formed by hall sensing components or photoelectric sensing components, or may be formed by other sensors that can be used for detecting positions, and are not limited in this respect.
