Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of new energy power generation equipment, in particular to a multi-angle magnetic suspension power generation device utilizing swing energy at various angles. BACKGROUND

[0002] There are many devices in real life with irregular swing characteristics, such as offshore floating devices: unmanned ships, offshore navigation lights, high-end hybrid yachts, etc. These devices will generate certain kinetic energy during the swing process. These devices are set in the ocean and other environments, need energy input and are not convenient for power transmission, and are usually powered by batteries, solar panels or fuel generators. The existing technology for power supply to marine devices also includes a wave power generation method, but most of the existing wave power generation devices are complex in structure, too large in size, and have low power generation efficiency and high cost due to mechanical friction and sealed friction during power generation.

[0003] Batteries and fuel generators need to be charged and refueled from time to time, and photovoltaic power generation is high in cost and has a decay in power generation efficiency. If the kinetic energy generated by the swing can be utilized, it can not only achieve economic and energy saving, but also appropriately improve the endurance of some devices. SUMMARY

[0004] The purpose of the present application is to provide a frictionless multi-angle magnetic suspension power generation device that can utilize the swing kinetic energy of the application device itself for power generation, is not limited by light and wind conditions, and is particularly suitable for application on offshore floating devices.

[0005] The technical solution of the present application is:

[0006] A multi-angle magnetic suspension power generation device, comprising: a magnetic suspension assembly, a power generation magnet and a shell, the magnetic suspension assembly comprises a cylindrical base magnet and a hemispherical suspension magnet, the upper end surface of the base magnet comprises a curved surface corresponding to the outer surface of the suspension magnet, the curved surface of the base magnet coincides with the surface of a sphere, the diameter of the sphere on which the curved surface of the base magnet is located is greater than the diameter of the sphere on which the suspension magnet is located, the base magnet is fixedly connected with the shell, the power generation magnet is connected with the suspension magnet, the lower end of the power generation magnet penetrates through the base magnet, and the shell is provided with a coil, the coil is connected with a storage battery through a rectifier circuit.

[0007] The outer surface of the suspension magnet is a partial spherical surface obtained by rotating a circular arc around a rotation axis by 360°, and one end point of the circular arc and the center of the circle on which the circular arc is located coincide on the rotation axis. The hemispherical suspension magnet is not limited to the length of the circular arc being equal to 1 / 4 of the circumference of the circle on which the circular arc is located. The length of the circular arc can be greater than 1 / 8 of the circumference of the circle on which the circular arc is located and less than 1 / 4 of the circumference of the circle on which the circular arc is located. Preferably, the length of the circular arc is greater than 1 / 8 of the circumference of the circle on which the circular arc is located and less than 1 / 4 of the circumference of the circle on which the circular arc is located.

[0008] The curved surface of the upper end of the base magnet is a portion of the sphere between two planes, obtained by cutting a sphere with two parallel planes. The center of the sphere is not between the two planes.

[0009] The magnetism at the top of the base magnet is the same as that on the outside of the levitation magnet. Since their like poles repel each other, the levitation magnet can float on the base magnet and rotate relative to it to a certain extent. Under the influence of only its own gravity and the repulsive force of the base magnet, without any other external forces, the spatial positions of the levitation magnet and the electromagnet remain stable.

[0010] In use, the shell is fixed to a buoy or other related equipment at sea. When the buoy moves, it causes the shell to move, which in turn causes the base magnet to move relative to the suspending magnet and the generating magnet. The coil on the shell cuts the magnetic lines of force generated by the generating magnet, thereby generating an electric current.

[0011] Preferably, the power-generating magnet is strip-shaped, passes through the suspension magnet, and the power-generating magnet and the suspension magnet are connected by a connecting mechanism that can adjust their upper and lower positional relationship.

[0012] The relative position of the generating magnet and the housing can be adjusted through the connecting mechanism, making the relative position of the magnetic field of the generating magnet and the coil variable. Through debugging, the optimal motion trajectory of the coil cutting the magnetic field lines of the generating magnet can be obtained, thereby improving the power generation performance.

[0013] Preferably, there are at least two power-generating magnets, which are parallel to each other and arranged in a circular array around the rotation axis of the levitation magnet. Each of the multiple power-generating magnets can be independently adjusted in position relative to the levitation magnet, further improving the variability of the relative position of the magnetic field of the power-generating magnet and the coil.

[0014] Preferably, the shell is barrel-shaped, the bottom wall of the shell is curved, the curved surface of the bottom wall of the shell coincides with the surface of a sphere, and the center of the sphere containing the bottom wall of the shell is located on the rotation axis of the levitation magnet.

[0015] The magnetic force is strongest and the magnetic field lines are densest at the end of the bar magnet. By making the bottom wall of the casing spherical, the bottom wall can stay close to the end of the magnet during shaking, regardless of the direction of shaking, thus improving power generation efficiency.

[0016] The number of coils is no less than two, and the coils are set on the bottom wall of the housing. Multiple coils are arranged in a dot matrix on the bottom wall of the housing, and the housing shakes randomly. Compared with the single coil method, the relative movement between the generating magnet and the housing can be effectively utilized to improve the power generation efficiency.

[0017] Preferably, at least two coils are provided on the bottom wall and side wall of the housing. Providing coils on the side wall of the housing also cuts the magnetic field lines in the middle of the generating magnet, improving power generation efficiency.

[0018] One structure of the connecting mechanism is as follows: the levitation magnet is a hemispherical shell structure, and the bottom of the levitation magnet is provided with a through hole. The connecting mechanism includes an adjusting sleeve, a funnel-shaped upper clamping member and a nut-shaped lower clamping member. The upper clamping member passes through the through hole of the levitation magnet and is threadedly connected to the lower clamping member. The adjusting sleeve is fixedly sleeved on the generator magnet. The outer surface of the adjusting sleeve is provided with threads. The upper clamping member is provided with a threaded hole that mates with the adjusting sleeve.

[0019] The levitation magnet has poor processing performance. However, the position adjustment of the power generation magnet and the levitation magnet can be achieved relatively easily through the connection mechanism of the above structure.

[0020] Specifically, the base magnet is fixed to the middle of the opening end of the housing by a bracket.

[0021] Specifically, the upper end of the housing is provided with a sealing end cap. After the sealing end cap is fastened, a sealed space is formed inside the housing, which can adapt to marine and other aquatic environments and reduce corrosion of the internal components of the housing.

[0022] Furthermore, the sealing end cap is curved, and the curved surface of the sealing end cap coincides with the surface of a sphere. The upper end of the generating magnet extends beyond the levitation magnet. The curved sealing end cap does not affect the swing of the upper end of the generating magnet. The distance between the upper end of the generating magnet and the sealing end cap is small, which can limit the levitation magnet to a certain extent and prevent the levitation magnet from detaching from the upper part of the base magnet, thereby destroying the magnetic levitation relationship between the two.

[0023] In practical applications, if this invention is used as an independent power generation device, a counterweight can be used to allow the multi-angle magnetic levitation power generation device to float vertically on the sea surface. The multi-angle magnetic levitation power generation device is connected to the shore power grid via cables. Regarding the fixing method of the multi-angle magnetic levitation power generation device in the ocean, multiple multi-angle magnetic levitation power generation devices can be connected in series or in a matrix. The ends of the series or matrix formed by the multi-angle magnetic levitation power generation devices are relatively fixed to the seabed, and adjacent multi-angle magnetic levitation power generation devices are connected by soft ropes.

[0024] A floating body, wherein the floating body is provided with a multi-angle magnetic levitation power generation device as described in claim 1.

[0025] The present invention can also be used to mount a multi-angle magnetic levitation power generation device on a floating body, such as a small ship, a marine buoy, or a floating board.

[0026] The advantages and positive effects of this invention are: by adopting the above technical solution, it is possible to generate electricity using the swaying kinetic energy of the equipment, which has the characteristics of simple structure, high power generation efficiency and high equipment stability.

[0042] Example 1

[0043] like Figures 1-7 As shown, the present invention:

[0044] A multi-angle magnetic levitation power generation device includes: a magnetic levitation component, a power generation magnet 3, and a housing 4. The magnetic levitation component includes a cylindrical base magnet 1 and a hemispherical suspension magnet 2. The upper end surface of the base magnet 1 includes a curved surface 11 corresponding to the outer surface of the suspension magnet. The curved surface of the base magnet coincides with the spherical surface of a sphere. The diameter of the sphere containing the curved surface of the base magnet is larger than the diameter of the sphere containing the suspension magnet 2. The base magnet 1 is fixedly connected to the housing 4. The power generation magnet 3 is connected to the suspension magnet 2. The lower end of the power generation magnet 3 passes through the base magnet 1. A coil 41 is provided on the housing 4. The coil is connected to a battery 6 through a rectifier circuit 5.

[0045] The outer surface of the levitation magnet 2 is a partial spherical surface obtained by rotating an arc 360° around a rotation axis 21, with one endpoint of the arc coinciding with the center of the circle containing the arc on the rotation axis 21. The hemispherical levitation magnet is not limited to the arc having a length equal to 1 / 4 of the circumference of the circle containing the arc; the arc can be longer than or shorter than 1 / 4 of the circumference. Preferably, the arc has a length greater than 1 / 8 and less than 1 / 4 of the circumference of the circle.

[0046] The curved surface 11 on the upper end of the base magnet is a part of the sphere between two planes obtained by cutting a sphere with two parallel planes. The center of the sphere is not between the two planes.

[0047] The magnetism at the upper end of the base magnet 1 is the same as that on the outer side of the levitation magnet 2. Since the like poles of the two repel each other, the levitation magnet 2 can float on the base magnet 1 and allows the levitation magnet 2 to rotate relative to the base magnet 1 to a certain extent. Under the condition that it is only subject to its own gravity and the repulsive force of the base magnet 1, and there are no other external forces, the spatial position of the levitation magnet 2 and the electromagnet 33 remains stable.

[0048] In use, the housing 4 is fixed to the marine buoy or other related equipment. When the marine buoy shakes, it causes the housing to shake. The housing causes the base magnet 1 to shake relative to the suspending magnet 2 and the power generation magnet 3. The coil 41 on the housing 4 cuts the magnetic lines of force generated by the power generation magnet, thereby generating current.

[0049] The power-generating magnet 3 is strip-shaped and passes through the suspending magnet 2. The power-generating magnet 3 and the suspending magnet 2 are connected by a connecting mechanism that can adjust their upper and lower positions.

[0050] Specifically,

[0051] The structure of the connecting mechanism is as follows: the levitation magnet 2 is a hemispherical shell structure, and the bottom of the levitation magnet 2 is provided with a through hole 22. The connecting mechanism includes an adjusting sleeve 23, a funnel-shaped upper clamping member 24 and a nut-shaped lower clamping member 25. The upper clamping member 24 passes through the through hole 22 of the levitation magnet and is threadedly connected to the lower clamping member 25. The adjusting sleeve 23 is fixedly sleeved on the generator magnet 3. The outer surface of the adjusting sleeve is provided with threads, and the upper clamping member is provided with a threaded hole that cooperates with the adjusting sleeve.

[0052] The relative position of the generating magnet 3 and the housing 4 can be adjusted through the connecting mechanism, so that the relative position of the magnetic field of the generating magnet 3 and the coil 41 can be changed. Through debugging, the optimal motion trajectory of the coil cutting the magnetic field lines of the generating magnet can be obtained, thereby improving the power generation performance.

[0053] There are four power-generating magnets 3, which are parallel to each other. Each power-generating magnet is fitted with an adjusting sleeve 23, and each power-generating magnet corresponds to a threaded hole on the clip 24.

[0054] Multiple generating magnets 3 can be independently adjusted in position with the levitation magnet 2, further improving the variability of the relative position of the magnetic field of the generating magnet and the coil.

[0055] The shell 4 is barrel-shaped, and the bottom wall 42 of the shell is curved. The curved surface of the bottom wall of the shell coincides with the surface of a sphere, and the center of the sphere containing the bottom wall of the shell is located on the rotation axis of the levitation magnet.

[0056] The magnetic force is strongest and the magnetic field lines are dense at the end of the bar magnet 3. By setting the bottom wall 42 of the shell to be spherical, the bottom wall of the shell can be close to the end of the magnet during the shaking process, regardless of the direction of shaking, thus improving the power generation efficiency.

[0057] The number of coils is no less than two, and the coils are set on the bottom wall 42 of the housing. The multiple coils are arranged in a dot matrix on the bottom wall of the housing, and the housing shakes randomly. Compared with the single coil method, the relative movement between the generating magnet and the housing can be effectively utilized to improve the power generation efficiency.

[0058] The levitation magnet has poor processing performance. However, the position adjustment of the power generation magnet and the levitation magnet can be achieved relatively easily through the connection mechanism of the above structure.

[0059] Specifically, the base magnet is fixed to the middle of the opening end of the housing by the bracket 7.

[0060] Specifically, the upper end of the housing is provided with a sealing end cap 8.

[0061] The working process of this example:

[0062] In use, the shell is fixed to the buoy and other related equipment. When the buoy moves, it causes the shell to move, which in turn causes the base magnet to move relative to the suspending magnet and the generating magnet. The coil on the shell cuts the magnetic lines of force generated by the generating magnet, thereby generating current. The current is connected to the battery through the rectifier circuit to power the buoy and other related equipment.

[0063] Regarding the calculation of the power generation efficiency of this invention: Assume the total weight of the generating magnet and the levitation magnet is 4 kg. During the oscillation process, the overall center of gravity of the generating magnet and the levitation magnet shifts vertically by 0.1 meters, and the oscillation period is 2 seconds. Therefore, the kinetic energy gained by the generating magnet and the levitation magnet in each period is 16 joules, and the power is 8 watts. The efficiency of converting mechanical energy into electrical energy in a typical generator can reach over 90%. This invention adopts a magnetic levitation frictionless design. Considering various losses, conservatively assuming a power generation efficiency of 80%, the power generation power of the multi-angle magnetic levitation power generation device of this invention is approximately 6.4 watts.

[0064] Example 2

[0065] like Figure 8 As shown,

[0066] The multi-angle magnetic levitation power generation device of the present invention can be equipped with a floating plate 9 on the outside of the shell and can be independently set in the ocean.

[0067] Specifically, the floating plate is fitted onto the lower part of the shell. By increasing the thickness of the bottom wall of the shell, the center of gravity of the multi-angle magnetic levitation power generation device is lowered, forming a self-righting structure. This arrangement can increase the swaying amplitude while ensuring that the device does not overturn, so as to convert ocean wave energy more efficiently.

[0068] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
