[0003] The present invention relates to the technical field of power generation, and in particular to an auxiliary driving device for a generator. Background Art

[0004] In the prior art, common power generation devices (such as generators) require an external power source to provide all the zero driving force when generating electricity, in order to overcome the magnetic field resistance inside the generator and realize the rotation and power generation of the generator. However, the external power source drive consumes a large amount of resources (such as coal, gas, oil, wind power, water power, etc.), which not only consumes a lot of resources and has high costs, but also has poor power generation efficiency.

[0005] Currently, no effective solution has been found to the problem that the generator in the related art requires an external power source to provide all the driving force when generating electricity, resulting in large consumption, high cost, and poor power generation efficiency.

[0006] Summary of the Invention

[0007] The purpose of the present invention is to provide a generator auxiliary drive device, which reduces the external power source to drive power generation while also having the advantages of simplifying the structure, reducing costs and improving power generation efficiency, and is suitable for popularization and use.

[0008] The purpose of the present invention can be achieved by adopting the following technical solutions:

[0009] The present invention provides a generator auxiliary drive device, the generator auxiliary drive device comprising:

[0010] A cylindrical outer stator, on which a power generation coil is arranged;

[0011] At least one annular first rotor, the first rotor being disposed inside the outer stator, the first rotor being circumferentially provided with a plurality of first magnets, wherein adjacent first magnets in the circumferential direction have opposite magnetic properties;

[0012] A plurality of second rotors rotatable along their own circumferential direction, the plurality of second rotors being arranged on the inner side of the first rotor along the circumferential direction of the first rotor, the plurality of second rotors being respectively provided with second magnets, the second magnets having first and second magnetic poles of opposite magnetic properties, and along the rotation direction of the first rotor, the following conditions are satisfied between any second magnet and two adjacent first magnets:

[0013] rotating the second magnet to a position where the first magnetic pole is opposite to the first magnet located downstream, and the first magnetic pole and the first magnet located downstream have opposite magnetic properties;

[0014] The second magnet is rotated to a position where the second magnetic pole is opposite to the first magnet located downstream, the second magnetic pole has opposite magnetic properties to the first magnet located downstream, and the second magnetic pole has the same magnetic properties as the first magnet located upstream.

[0015] The beneficial effects of the present invention are:

[0016] A first rotor is arranged on the inner side of an outer stator, and a plurality of first magnets are arranged on the first rotor along the circumferential direction, and two adjacent first magnets in the circumferential direction of the first rotor are arranged to have opposite magnetic properties. A plurality of second rotors that can rotate along their own circumferential direction are arranged on the inner side of the first rotor along the circumferential direction of the first rotor. The plurality of second rotors are respectively provided with second magnets, and the second magnets are arranged to have first magnetic poles and second magnetic poles with opposite magnetic properties. Along the rotation direction of the first rotor, the following starting principle must be satisfied between any second magnet and its two adjacent first magnets:

[0017] (1) Rotate the second magnet to a position where the first magnetic pole is opposite to the first magnet located downstream, and the first magnetic pole has opposite magnetism to the first magnet located downstream; rotate the second magnet to a position where the second magnetic pole is opposite to the first magnet located downstream (i.e., the first magnet at the original position is replaced by the first magnet located downstream), the second magnetic pole and the first magnet located downstream always have opposite magnetism, and the second magnetic pole and the first magnet located upstream always have the same magnetism. By rotating the second rotor, the positional relationship between the first magnetic pole and the second magnetic pole on the second magnet and the first magnet changes. When the first magnetic pole of the second magnet opposite to the first magnet located downstream changes to the second magnetic pole, the second magnet and the first magnet located downstream always attract each other, while the second magnet and the first magnet located upstream always repel each other. Then, through the interaction between the second magnet and the two first magnets located upstream and downstream, the position of the first magnet is pushed to change, thereby causing the first rotor to rotate.

[0018] (2) The twelve first magnets in the first rotor are divided into two groups and work simultaneously (i.e., group 1 is the first to sixth magnets arranged in sequence, and group 2 is the seventh to twelfth magnets arranged in sequence). When the first magnets are pressed into the same end face as the generating coil and the second magnet, the first rotor and the first magnets rotate. The adjacent first magnets (among the first five first magnets) located upstream of any first magnet interact with the adjacent second magnets (among the first five second magnets) located upstream of the corresponding second magnet, thereby driving the first rotor as a whole to rotate counterclockwise. At the same time, the rack on the side of the first rotor drives the gear to rotate. The other first magnets interact with the corresponding second magnets in the same way, so that the first rotor as a whole can rotate counterclockwise, thereby reducing the driving force of the external power source and playing an auxiliary driving role in driving the generator. While reducing the load of the external power source, it can also reduce the magnetic field resistance inside the generator auxiliary drive device, improve the power generation efficiency, and make the generator auxiliary drive device of the present invention have a wider range of uses.

[0040] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described with reference to the accompanying drawings.

[0041] As shown in Figures 1 to 14, the present invention provides a generator auxiliary drive device, which includes an outer stator 14, at least one first rotor 13 and a plurality of second rotors 1 that can rotate along their own circumferential direction. The outer stator 14 is cylindrical, and a power generation coil 12 is arranged inside the cylinder wall of the outer stator 14; the first rotor 13 is annular, and the first rotor 13 is arranged on the inner side of the outer stator 14 (that is, the outer stator 14 is sleeved on the outer side of the first rotor 13). A plurality of first magnets 2 are spaced and evenly arranged on the first rotor 13 along its circumferential direction, and two adjacent first magnets 2 in the circumferential direction of the first rotor 13 have opposite magnetic properties; a plurality of second rotors 1 are arranged on the inner side of the first rotor 13 along the circumferential direction of the first rotor 13, and a plurality of second magnets 8 are respectively provided on the plurality of second rotors 1, and the second magnets 8 have magnetic opposite magnetic properties. With respect to the first and second opposite magnetic poles, along the rotation direction of the first rotor 13, the following conditions are satisfied between any second magnet 8 and its two adjacent first magnets 2: when the second magnet 8 is rotated to a position where the first magnetic pole is opposite to the first magnet 2 located downstream (i.e., the first magnet 2 located behind the two first magnets 2 in the rotation direction of the first rotor 13 as indicated by the arrow in FIG1 ), the first magnetic pole and the first magnet 2 located downstream have opposite magnetic properties; when the second magnet 8 is rotated to a position where the second magnetic pole is opposite to the first magnet 2 located downstream, the second magnetic pole and the first magnet 2 located downstream have opposite magnetic properties, and the second magnetic pole and the first magnet 2 located upstream (i.e., the first magnet 2 located in front of the two first magnets 2 in the rotation direction of the first rotor 13 as indicated by the arrow in FIG1 ) have the same magnetic properties.

[0042] In the present invention, a first rotor 13 is disposed inside an outer stator 14. A plurality of first magnets 2 are circumferentially arranged on the first rotor 13, and adjacent first magnets 2 in the circumferential direction of the first rotor 13 are arranged to have opposite magnetic properties. A plurality of second rotors 1 are rotatable along their own circumferential direction and disposed inside the first rotor 13 along the circumference of the first rotor 13. Second magnets 8 are respectively disposed on the plurality of second rotors 1, and the second magnets 8 are arranged to have first and second magnetic poles with opposite magnetic properties. Along the rotation direction of the first rotor 13, the following starting principle must be satisfied between any second magnet 8 and its two adjacent first magnets 2:

[0043] [Corrected 10.02.2025 according to Rule 91] 1. Rotate the second magnet 8 to a position where its first magnetic pole is opposite to the downstream first magnet 2, and the first magnetic pole and the downstream first magnet 2 have opposite magnetic properties; rotate the second magnet 8 to a position where its second magnetic pole is opposite to the downstream first magnet 2 (i.e., the first magnet 2 in its original position is replaced by the downstream first magnet 2), so that the second magnetic pole and the downstream first magnet 2 always have opposite magnetic properties, and the second magnetic pole and the upstream first magnet 2 have the same magnetic properties. By rotating the second rotor 1, the positional relationship between the first and second magnetic poles of the second magnet 8 and the first magnet 2 changes. When the first magnetic pole of the second magnet 8 opposite the downstream first magnet 2 changes to the second magnetic pole, the second magnet 8 and the downstream first magnet 2 change from being always attracted to each other to being repelled (the first magnet 2 is located upstream of the second magnet 8), while the second magnet 8 and the upstream first magnet 2 always repel each other. The interaction between the second magnet 8 and the upstream and downstream first magnets 2 causes the position of the first magnet 2 to change, thereby causing the first rotor 13 to rotate.

[0044] Second, the twelve first magnets 2 in the first rotor 13 are divided into two groups and operate simultaneously (i.e., group 1 comprises the first to sixth magnets arranged in sequence, and group 2 comprises the seventh to twelfth magnets arranged in sequence). When the first magnets 2 are pressed into the same end surface as the generator coil 12 and the second magnet 8, the first rotor 13 and the first magnets 2 rotate. The adjacent first magnets 2 (among the first five first magnets 2) located upstream of any first magnet 2 interact with the adjacent second magnets 8 (among the first five second magnets 8) located upstream of the corresponding second magnet 8, thereby driving the first rotor 13 to rotate counterclockwise as a whole (as shown in FIG. 1 ). Simultaneously, the rack 3 on the side of the first rotor 13 drives the gear 7 to rotate. Similarly, the other first magnets 2 interact with the corresponding second magnets 8, thereby enabling the first rotor 13 to rotate counterclockwise as a whole (as shown in FIG. 1 ). The present invention generates current in the generator coil 12 arranged on the outer stator 14 through changes in the magnetic field. The present invention can play an auxiliary driving role in the generator driven by the external power source through the change and interaction of the magnetic force between the second magnet 8 and the first magnet 2. While reducing the load of the external power source, it can also reduce the magnetic field resistance inside the generator auxiliary drive device, reduce the torque of the external driving force, and improve the power generation efficiency, so that the generator auxiliary drive device of the present invention has a wider range of uses.

[0045] In an optional embodiment of the present invention, the generator auxiliary drive device further includes an external drive device (not shown), the power output end of the external drive device is connected to the first rotor 13 and / or the second rotor 1. In some scenarios, the first rotor 13 and / or the second rotor 1 can be driven to rotate by the external drive device to ensure the normal operation of the generator auxiliary drive device of the present invention. By connecting the power output end of the external drive device to the first rotor 13 and / or the second rotor 1, the external drive device can drive the first rotor 13 and / or the second rotor 1 to rotate, and the external drive device can provide kinetic energy to ensure that the first rotor 13 and the second rotor 1 can generate relative motion. Under the drive of the external drive device, the first magnet 2 on the first rotor 13 and the second magnet 8 on the second rotor 1 can move to a preset position, thereby ensuring that the first rotor 13 can rotate smoothly. Of course, in some scenarios, the above-mentioned consumption of magnetic energy between the first magnet 2 and the second magnet 8 to drive the first rotor 13 to rotate plays an auxiliary role, and the main power source for the rotation of the first rotor 13 comes from the external drive device. In this case, the torque of the external drive force is reduced, thereby improving the power generation efficiency of the generator.

[0046] Among them, the external driving device can be a wind-driven, fire-driven or other form of driving device that can drive the first rotor 13 and / or the second rotor 1 to rotate. Those skilled in the art can make a choice according to actual conditions. Therefore, the specific external driving device used is not specifically limited here.

[0047] In an optional embodiment of the present invention, as shown in Figures 1, 2, 15, and 16, the generator coils 12 are disposed within the cylindrical wall of the outer stator 14. Multiple generator coils 12 are spaced and evenly distributed along the circumference of the outer stator 14. In the axial direction of the outer stator 14, the generator coils 12, the first magnets 2, and the second magnets 8 are axially opposed. Therefore, during the rotation of the first rotor 13, each first magnet 2 can cut the magnetic flux lines, causing a certain current to flow through the generator coils 12.

[0048] In an optional embodiment of the present invention, as shown in Figures 1 to 3, the second rotor 1 includes a gear 7, and the second magnet 8 is disposed on the gear 7. The generator auxiliary drive device also includes a central shaft 6 and at least one disc-shaped transmission mechanism 11. The transmission mechanism 11 is disposed on the inner side of the first rotor 13 along the circumference of the first rotor 13. The inner wall surface of the transmission mechanism 11 is provided with multiple racks 3 along its circumference. The teeth on the racks 3 can mesh with the teeth on the gear 7. The transmission mechanism 11 drives the multiple racks 3 to move along the circumference of the transmission mechanism 11, and the multiple racks 3 drive the gears 7 moved to their corresponding positions to rotate, thereby changing the position of the first and second magnetic poles on the second magnet 8 (i.e., the second magnetic pole on the second magnet 8 rotates to the position where the first magnetic pole was originally located, or the first magnetic pole on the second magnet 8 rotates to the position where the second magnetic pole was originally located). The central shaft 6 is connected to the first rotor 13 by a bearing and is connected to the outer stator brackets 28 on both sides of the outer stator 14 by a flat key.

[0049] In a specific embodiment of the present invention, as shown in Figure 1, multiple second rotors 1 and multiple first magnets 2 are respectively spaced and evenly arranged along the circumference of the first rotor 13; preferably, the arc length of the rack 3 is half the circumference of the gear 7, and the arc length corresponding to the interval between two adjacent racks 3 is five times the arc length of one rack 3. The number of second rotors 1 is at least ten, and the arc length corresponding to the interval between two adjacent second rotors 1 is five times the half circumference of the gear 7; the number of first magnets 2 is at least twelve, and the arc length corresponding to the interval between two adjacent first magnets 2 is five times the half circumference of the gear 7.

[0050] Specifically, as shown in FIG1 , the second magnets 8 on the ten second rotors 1 (i.e., five pairs of second magnets 8 ) in the generator auxiliary drive device can rotate circumferentially, while the twelve first magnets 2 (i.e., six pairs of first magnets 2 ) on the first rotor 13 cannot rotate. The first rotor 13 is set to rotate counterclockwise (as indicated by the arrow on the first rotor 13 in FIG1 ). During startup, the multiple second rotors 1 can be in any position. When the multiple first magnets 2 are pressed into a predetermined position (i.e., the multiple first magnets 2, the multiple second magnets 8, and the generator coil 12 are in the same plane), the first rotor 13 begins to rotate (the rack 3 is fixedly connected to the first rotor 13). The rack 3 cooperates with the gear 7 to change the position of the first magnetic pole and the second magnetic pole of each second magnet 8 (the second magnet 8 rotates 180°). Through the rotation of the first magnets 2 and the first rotor 13, the magnetic field generated by the first magnets 2 cuts the generator coil 12, causing the generator coil 12 to generate current.

[0051] In an optional embodiment of the present invention, as shown in Figures 1, 2, 5, 6 to 9, and 12 to 14, the central shaft 6 is a hollow shaft with a cylindrical shape and openings at both ends. A sliding hole 21 that is connected to the interior of the central shaft 6 is provided on the middle wall of the central shaft 6. The sliding hole 21 is a long hole extending along the axial direction of the central shaft 6. A sliding rod 20 that can slide along the axial direction of the central shaft 6 is provided inside the central shaft 6. One end of the sliding rod 20 is located inside the central shaft 6, and the other end of the sliding rod 20 extends from the opening at one end of the central shaft 6 to the outside of the central shaft 6. The outside of the central shaft 6 is provided with a first annular sliding sleeve 19 that can slide along the axial direction of the central shaft 6. A screw (not shown) is provided in the sliding hole 21, and one end of the screw is connected to the The first sleeve 19 is connected to the slide rod 20, and the other end of the screw is connected to the first sleeve 19. The outer periphery of the first sleeve 19 is provided with an annular second sleeve 24. Multiple pressure plates 17 (or connecting rods) are connected between the first sleeve 19 and the second sleeve 24. The annular inner wall surface of the second sleeve 24 is provided with a pressure plate groove 27 along its circumference. The annular outer wall surface of the second sleeve 24 is provided with multiple sliders 18 corresponding to the first magnets 2 along its circumference. The multiple sliders 18 are connected to the corresponding first magnets 2. By controlling the axial movement of the slide rod 20 along the central axis 6, the first magnets 2 can be driven to move axially along the central axis 6, thereby adjusting the relative axial position of the first magnets 2 and the power generation coil 12 and the second magnet 8. When the first magnets 2 are adjusted to a position axially opposite to the power generation coil 12 and the second magnet 8, the first rotor 13 and the first magnets 2 rotate, and the magnetic lines of force of each first magnet 2 cut through the power generation coil 12. When the first magnets 2 are adjusted to be axially offset from the power generation coil 12 and the second magnet 8, the first magnets 2 cannot cut through the power generation coil 12.

[0052] 7 and 8 , the slide rod 20 is provided with a threaded hole 23, and the screw rod is connected to the threaded hole 23 by a threaded fit. Of course, the threaded hole 23 can also be provided on the first sleeve 19 to meet the connection requirements of the screw rod, the slide rod 20 and the first sleeve 19.

[0053] In an optional embodiment of the present invention, as shown in Figures 15 and 16, the generator auxiliary drive device also includes an annular inner stator 15 and an assembly frame 4, the inner stator 15 and the assembly frame 4 are both arranged in an annular manner on the outer periphery of the central shaft 6, and the inner stator 15 is arranged on the inner side of the outer stator 14 and the first rotor 13, as shown in Figures 2, 5, 9 and 10, a chamber 25 is formed in the second rotor 1, the second magnet 8 is located in the chamber 25, the gear 7 is arranged on the outer wall of the second rotor 1 and is rotatably connected to the position of the inner stator 15 near the annular outer edge; the assembly frame 4 is connected to the inner wall of the first rotor 1 by a sealing ring, the assembly frame 4 is fixedly connected to the central shaft 6 by a flat key on the shaft, the central shaft 6 is connected to the first rotor 13 by a bearing, and the central shaft 6 is connected to the outer stator brackets 28 on both sides of the outer stator 14 by a flat key.

[0054] In an optional embodiment of the present invention, as shown in FIG. 1 and FIG. 2 , the second rotor 1 further includes a check device 5 , which is used to limit the rotation angle of the gear 7 .

[0055] Furthermore, as shown in Figures 1, 2, 4, and 11, a convex portion 10 is provided on the inner wall surface of the first rotor 13, which is opposite to the plurality of racks 3. Along the rotation direction of the transmission mechanism 11, the convex portion 10 is in the shape of an arc slope with a gradually increasing inclination angle; the backstop device 5 includes a first backstop 501 and a limit rod 16, the first end of the limit rod 16 is connected to the first backstop 501, and the second end of the limit rod 16 can be against the inner wall surface of the first rotor 13; the gear 7 has at least a rotating state and a locked state, as shown in Figures 18 to 20, when the gear 7 is in the rotating state, the rack 3 gradually approaches the corresponding gear 7, and the limit rod 16 The second end of the limit rod 16 slides to a position against the protrusion 10 and slides on the protrusion 10 in a direction of gradually increasing inclination angle. At this time, the first backstop 501 gradually opens. When the second end of the limit rod 16 slides to the position of maximum height on the protrusion 10, the first backstop 501 is fully opened. At this time, the rack 3 and the gear 7 are just engaged. The first rotor 13 continues to rotate by the length of the rack 3. The rack 3 drives the corresponding gear 7 to rotate. The first rotor 13 continues to rotate and the limit rod 16 will pass over the protrusion 10 to reach the position of the recess 26. At this position, the first backstop 501 can lock the gear 7 to put the gear 7 in a locked state. Among them, the first backstop 501 can adopt an existing backstop, and the specific structure of the first backstop 501 is not limited in the present invention.

[0056] Furthermore, as shown in Figures 1 and 2 , the backstop device 5 also includes a second backstop 502. The cam on the second backstop 502 engages with the teeth on the gear 7 to prevent the gear 7 from rotating in the opposite direction, thereby ensuring that the second rotor 1 always rotates in one direction (counterclockwise as shown in Figure 1 ). The second backstop 502 can be an existing backstop, and the specific structure of the second backstop 502 is not limited in the present invention.

[0057] In an optional embodiment of the present invention, as shown in Figures 15 to 17, the first rotor 13 in the above embodiment can be exchanged with the multiple second rotors 1, that is, the multiple second rotors 1 are arranged on the outer periphery of the first rotor 13 along the circumference of the first rotor 13, and the generating coil 12 is arranged on the inner side of the first rotor 13.

[0058] In an optional embodiment of the present invention, as shown in FIG15 , a plurality of heat dissipation holes 9 are provided on the inner stator 15 .

[0059] The generator auxiliary drive device of the present invention may be, but is not limited to, a generator, and may also be extended to other engine equipment.

[0060] The working principle of the present invention is as follows: a plurality of first magnets 2 (12 pieces in FIG. 1 ) are arranged circumferentially and at equal intervals on the first rotor 13, and two circumferentially adjacent first magnets 2 have opposite magnetic properties. The number of second rotors 1 is a plurality of (10 in FIG. 1 , 5 adjacent second rotors 1 form a group, which can be divided into two groups) arranged circumferentially along the first rotor 13. The second rotor 1 can rotate circumferentially on its own. A second magnet 8 is provided on each second rotor 1, and each second magnet 8 has a first magnetic pole and a second magnetic pole with opposite magnetic properties. By setting the preset positions of the first magnet 2 and the second magnet 8, that is, rotating the second magnet 8 to a position where the first magnetic pole is opposite to the first magnet 2 located downstream, and the second magnet 8 to a position where the second magnetic pole is opposite to the first magnet 2 located downstream (the first magnet 2 in the original position is moved by the first magnet located downstream thereof). The second magnet 8 is replaced by iron 2, ensuring that the second magnetic pole and the first magnet 2 located downstream always have opposite magnetic properties, while the second magnet 8 and the first magnet 2 located upstream have the same magnetic properties. This results in the second magnet 8 and the first magnet 2 located downstream switching from mutual attraction to mutual repulsion, while the second magnet 8 and the first magnet 2 located upstream repel each other. Furthermore, the interaction between the second magnet 8 and the two upstream and downstream first magnets 2 achieves the purpose of pushing the first magnet 2 to change position. Because the driving force exerted by the second magnet 8 on the second rotor 1 on the first magnet 2 in the first rotor 13 is far greater than the resistance to the magnetic field generated by the second rotor 1 during rotation, the first rotor 13 is able to rotate, providing partial power for the generator auxiliary drive device to generate electricity, thereby improving power generation efficiency. During rotation, due to the magnetic force, the second rotor 13 rotates, completing the magnetic pole switching, achieving continuous rotation.

[0061] In the present invention, magnetic energy needs to be consumed in the process of realizing the rotation of the first rotor 13. Due to the consumption of magnetic energy, the auxiliary drive device of the generator needs to be regularly replenished with energy (current magnetization). Taking neodymium iron boron magnets as an example, in order to obtain magnetic energy, a single magnet needs to be magnetized multiple times through a "pulse magnetizer" by passing a momentary pulse of large current (tens of thousands of amperes) in the magnetizing coil. The magnet is repeatedly magnetized by generating a short-term ultra-strong magnetic field. A large amount of electrical energy is consumed in the process, and the magnet obtains magnetic energy (promoting the movement directions of electrons in the outer layers of all atomic nuclei in the magnet to be aligned, so that the magnet has huge magnetic energy). That is to say, the first rotor 13 in the present invention needs to consume a large amount of electrical energy to obtain magnetic energy. The consumed electrical energy is consumed when acting on the magnetic material to guide the movement directions of electrons outside all atomic nuclei of the magnetic material to be aligned. In this process, electrical energy is converted into magnetic energy; in addition, in the process of relative rotation between the first rotor 13 and the second rotor 1, the kinetic energy generated by the first rotor 13 needs to consume magnetic energy. That is to say, the first rotor 13 consumes magnetic energy to convert it into its own kinetic energy, and the rotation of the first rotor 13 cuts the generating coil 12 and then converts it into electrical energy. In this process, magnetic energy is converted into kinetic energy and then into electrical energy.

[0062] The magnets used in the auxiliary drive device of the generator of the present invention can be neodymium iron boron magnets. According to the characteristics of the above-mentioned permanent magnets that can be magnetized and have very low magnetic energy consumption, the first rotor 13 and the second rotor 1 of the present application are manufactured, and the continuous and stable working state of the auxiliary drive device of the generator is achieved through regular magnetization.

[0063] The above description is only an illustrative embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principle of the present invention shall fall within the scope of protection of the present invention.
