Description

Technical Field

[0001] The present invention relates to a power generation device that generates electricity by a rotor rotatably provided on a main body frame and a stator provided on the main body frame.

Background Art

[0002] In recent years, the demand for electricity has been increasing in various fields, and a power generation device that efficiently generates electricity is required. As one type of power generation device, there is a type in which a permanent magnet is rotated as a rotor, the magnetic flux generated by the permanent magnet is guided to a stator, and electricity is induced in the winding of the stator. Among various proposals for such power generation devices, the technologies disclosed in Patent Document 1 and Patent Document 2 are known.

[0003] The technology of Patent Document 1 includes a rotating shaft, a rotating magnet holder coupled to the rotating shaft and configured to be rotatable, a plurality of permanent magnets arranged on the rotating magnet holder in a state where magnetic poles face the same pole, and a power generation coil arranged around the rotating magnet holder and the plurality of permanent magnets. A plurality of rotating magnet holders are stacked and coupled to the rotating shaft to form a rotary power generation device. With such a configuration, it is possible to reduce the amount of permanent magnets used and achieve weight reduction.

[0004] However, in the power generation device of Patent Document 1, the power generation coil is arranged only around the rotating magnet holder and the plurality of permanent magnets, or only four power generation coils are arranged in a portion close to the outer peripheral portion between the stacked rotating magnet holders. Only a part of the magnetic flux generated by the permanent magnet is utilized, resulting in a decrease in power generation efficiency. Also, when adjusting the amount of generated electricity, it is only possible to adjust by the rotation speed of the rotating magnet holder, and it is difficult to adjust the amount of electricity.

[0005] The power generation device of Patent Document 2 uses a permanent magnet holder in which the magnetic poles of permanent magnets are arranged so as to repel each other with the same poles as the rotor, and an electromagnetic conversion element with a winding as the stator. The electromagnetic conversion element is configured such that a substantially U-shaped magnetic core forms a substantially closed magnetic circuit of an independent magnetic circuit. As the generated power of the power generation coil increases, the electromagnetic conversion element is arranged away from the permanent magnet to reduce the cogging torque and reduce the rotational force required for power generation.

[0006] However, in the power generation device of Patent Document 2, the power generation coil is arranged only around the permanent magnet holder provided with the permanent magnet, and only a part of the magnetic flux generated from the permanent magnet is utilized, so that the power generation efficiency is still reduced. In addition, when adjusting the amount of power generated, it is only possible to adjust by the rotation speed of the rotating magnet holder, and it is difficult to adjust the amount of power generated.

[0027] Next, the main body frame 11 will be described. The main body frame 11 is formed in a frame shape that is substantially rectangular parallelepiped. A support bar 11a is spanned from the left side end portion to the right side end portion of the main body frame 11, and a pair of vertical guide rails 12 are provided at predetermined intervals so as to extend in the vertical direction in the figure to guide and support the detachable stator mechanism 40.

[0029] The vertical guide rail 12 includes a guide groove 12a that guides and supports the detachable stator mechanism 40, and a terminal portion (not shown) that contacts the terminal portion 42 of the detachable stator mechanism 40 to conduct electricity.

The rotational force input mechanism 20 includes a bearing portion 21 provided on the first side plate 14, a shaft 22 rotatably provided in the bearing portion 21, a handle 23 provided on the shaft 22 and graspable by hand, and a drive gear 24 provided on the shaft 22. In the embodiment, the rotational force input mechanism 20 is a manual type, but it is not limited thereto, and it may be a type rotated by natural energy or a type rotated by an internal combustion engine or the like.

[0031] Next, the rotor 30 will be described. The rotor 30 includes a rotating shaft 31 rotatably provided in the first bearing portion 16 and the second bearing portion 17 of the main body frame 11 and rotated by an external force, a driven gear 31a provided on the rotating shaft 31 and meshing with the drive gear 24, a positioning member 32 for determining the position of the rotating shaft 31 in the thrust direction, a disk disk 33 provided via a fixing portion 34 so as to rotate integrally with the rotating shaft 31 and having a disk shape extending in a direction perpendicular to the axis of the rotating shaft 31, a magnet groove 35 formed radially outward from the center on the disk disk 33, and a permanent magnet 36 provided radially outward from the center on the disk disk 33 via the magnet groove 35 and generating a magnetic flux.

[0032] Further, the disk disk 33 has a shaft hole 34a and a key groove 34b formed in a fixing portion 34 fixed to the rotating shaft 31. The disk disk 33 is provided so as to be replaceable with another disk disk 33 by moving it in the thrust direction.

[0033] A plurality of disk disks 33 are provided laminated on the rotating shaft 31 at a predetermined interval. The permanent magnets 36 provided on the disk disks 33 are arranged such that the opposing magnetic poles 36n, 36s of adjacent permanent magnets 36 repel each other. For example, the N poles 36n are arranged to repel each other, and the S poles 36s are arranged to repel each other.

[0034] Next, the detachable stator mechanism 40 will be described. The detachable stator mechanism 40 is disposed between the disk disks 33 arranged in a laminated manner. The detachable stator mechanism 40 includes a lock plate 41 that is detachably provided by being guided by the vertical guide rail 12 and has an electric circuit, and a special transformer 50 that is provided on the lock plate 41 and generates electricity by a change in magnetic flux. The lock plate 41 also has the function of a substrate and can also be said to be a detachable substrate that can be attached to and detached from the vertical guide rail 12. The special transformer 50 is detachable from the lock plate 41 and can also be said to be a detachable coil because it generates electricity by a change in magnetic flux.

[0035] The lock plate 41 includes a terminal portion 42 that conducts electricity from the special transformer 50 in contact with the terminal of the vertical guide rail 12, a notch groove 43 for the shaft that avoids the rotating shaft 31 when attached to the vertical guide rail 12, an inclined portion 44 for facilitating guidance in the guide groove 12a of the vertical guide rail 12, a plurality of coil attachment portions 45 to which the special transformer 50 is attached, and a handle 46 for easily holding the lock plate 41 by hand.

[0036] Next, the special transformer 50 will be described. As shown in FIGS. 1 to 6, the special transformer 50 includes a bobbin 51 with an opening in the center, a winding (not shown) wound around the bobbin 51, and a terminal 52 provided to protrude from the bobbin 51 and connected to the winding. The terminals 52 are connected by inserting them into the coil attachment portions 45 of the lock plate 41. A plurality of special transformers 50 can be attached to the lock plate 41. The outer size of the special transformer 50 is 1 / 10 or less of the outer diameter of the disk disk 33. Thereby, the special transformers 50 can be arranged in 10 columns vertically and 10 rows or more horizontally with respect to the outer diameter of the disk disk 33. In FIG. 5, the special transformers 50 can be arranged in 14 columns vertically and 14 columns horizontally. FIG. 6(C) shows the circuit of the special transformer 50, and a three-phase coupling method is used. In the embodiment, the circuit of the special transformer 50 is configured as shown in FIG. 6(C), but it is not limited thereto. The special transformer 50 may be a coil in which a single conducting wire is wound around the bobbin 51 a plurality of times. In this case, the special transformer 50 can also be said to be a detachable coil.

[0037] Also, the winding in the special transformer 50 may be a single winding, but is not limited thereto, and two windings may be wound like a so-called transformer. In this case, a plurality of terminal portions 42 may be provided on the lock plate 41. As an example, when inputting 0.75 horsepower (0.5516 kW) to the rotating shaft 31, the rotational speed becomes 600 rpm, the voltage per special transformer 50 is 26 V, and the current is 10.3 to 16 A. Note that an inverter may be provided in the power generation device 10.

[0038] Next, the operation of the power generation device of Example 1 will be described. As shown in FIG. 7, the power generation device 10 has seven disk disks 33 arranged in a stacked manner, and six detachable stator mechanisms 40 are arranged therebetween. The detachable stator mechanism 40 is set by guiding the edge of the lock plate 41 (see FIG. 5) along the guide groove 12a (see FIG. 3) of the vertical guide rail 12.

[0039] Further, an electric circuit (not shown) for guiding the electricity generated by the special transformer 50 is provided on the lock plate 41. When not all of the special transformers 50 are set in the coil mounting portion 45, a dummy energizing member (not a coil) that only energizes the coil mounting portion 45 may be mounted. Furthermore, even if the dummy energizing member is not mounted, an electric circuit that can maintain the energized state may be provided, and a contact (point) may be provided such that the circuit switches to the special transformer 50 side when the special transformer 50 is mounted. Also, the electric circuit may be in parallel, series, or either.

[0040] In the embodiment, the detachable stator mechanism 40 is mounted on all the vertical guide rails 12, but is not limited thereto, and the detachable stator mechanism 40 may be mounted on only some of the vertical guide rails 12. In this case, when an electric circuit (not shown) provided in the main body frame 11 is connected to the terminal portion 42 of each detachable stator mechanism 40, the detachable stator mechanism 40 is energized, and the portion where the detachable stator mechanism 40 is not mounted is not disconnected, but an electric circuit that can be energized as it is without passing through the detachable stator mechanism 40 is provided.

Example

[0041] Next, the power generation device 10 of Example 2 will be described. The components common to the power generation device 10 of Example 1 will be described with reference numerals and the description thereof will be omitted.

[0042] As shown in FIGS. 8 to 10, in the power generation device 10, the main body frame 11 includes an outer peripheral member 61 that surrounds the outer periphery of the disk 33, and a plurality of outer peripheral transformers 60 that are provided at positions facing the outer peripheral surface of the disk 33 of the outer peripheral member 61 and generate electricity due to changes in magnetic flux. Since the outer peripheral transformer 60 is arranged on the outer periphery of the disk 33 and generates electricity due to changes in magnetic flux, it can also be referred to as an outer peripheral coil.

[0043] The outer peripheral transformers 60 are arranged at predetermined intervals. Thereby, the outer peripheral transformers 60 arranged on the outer periphery of the disk 33 can also generate electricity, and the device as a whole can generate electricity efficiently. Thirty outer peripheral transformers 60 are provided on the outer periphery of one disk 33, and a total of sixty are provided on the outer peripheries of two disks 33. In the embodiment, two disks 33 are used, but it is not limited thereto, and three, four, five or more may be used. Also, although thirty outer peripheral transformers 60 are provided on the outer periphery of one disk 33, it is not limited thereto, and twenty, twenty-five, thirty-five, forty, etc. of the outer peripheral transformers 60 may be arranged on the outer periphery of one disk 33, and the number does not matter.

[0044] Further, the permanent magnets 36 are provided radially outward from the center of the disk 33. However, since the gap between the magnets is larger in the portion closer to the outer peripheral end than the central portion, the permanent magnet 36 includes a long magnet 36a and a short magnet 36b shorter than the long magnet 36a in the gap portion. Also, a tapered portion 31a is provided at the end of the rotating shaft 31, and an oil passage 31b for guiding lubricating oil to the tapered portion 31a is provided.

[0045] The effects of the power generation device 10 described above will be described below. In the configuration of the embodiment of the present invention, the rotor 30 includes a disk disk 33 provided to rotate integrally with the rotating shaft 31 and having a disk shape extending in a direction perpendicular to the axis of the rotating shaft 31, and permanent magnets 36 provided radially outward from the center on the disk disk 33 to generate magnetic flux. Therefore, the permanent magnets 36 can be arranged over the entire area of the disk disk 33, and a large magnetic flux can be generated. The detachable stator mechanism 40 can arrange the special transformer 50 at a position facing the entire area of the disk disk 33 when the lock plate 41 is guided by the vertical guide rail 12, and can generate electricity efficiently using as much of the large magnetic flux as possible. Further, since the detachable stator mechanism 40 includes a lock plate 41 provided detachably by being guided by the vertical guide rail 12, by providing coils with different numbers of turns of windings, etc. on different lock plates 41 in advance, the amount of electric power generated can also be adjusted by replacing the lock plate 41.

[0046] Furthermore, a plurality of disk disks 33 are provided stacked at intervals on the rotating shaft 31, and since the detachable stator mechanism 40 can be arranged between each of the disk disks 33, a plurality of disk disks 33 can be rotated by rotating a single rotating shaft 31. By arranging the detachable stator mechanism 40 between the plurality of stacked disk disks 33, a large total amount of magnetic flux can be generated, and the magnetic flux can be used as much as possible to generate electricity efficiently. Further, it is also possible to adjust the amount of electric power generated for each individual detachable stator mechanism 40.

[0047] Furthermore, the lock plate 41 includes a plurality of coil attachment portions 45 to which the special transformer 50 is attached. The special transformer 50 includes a terminal 52 that protrudes from the bobbin 51 and is connected to the winding. By inserting the terminal 52 into the coil attachment portion 45, a plurality of special transformers 50 can be attached to the lock plate 41. Therefore, by attaching a large number of special transformers 50 to the lock plate 41, the magnetic flux generated from the front surface of the disk 33 can be used as efficiently as possible to generate electricity efficiently. Furthermore, by changing the number and type of the special transformers 50 attached to the lock plate 41, the amount of generated electricity can also be adjusted.

[0048] Furthermore, since the outer size of the special transformer 50 is 1 / 10 or less of the outer diameter of the disk 33, the special transformers 50 can be arranged in 10 columns vertically and 10 rows or more horizontally with respect to the outer diameter of the disk 33, and the generated magnetic flux can be used as efficiently as possible to generate electricity efficiently.

[0049] Furthermore, since the lock plate 41 includes a notch groove 43 for the shaft to avoid the rotating shaft 31 when being attached to the vertical guide rail 12, the lock plate 41 can be inserted to the deepest position and opposed from one end to the other end of the disk 33, and the generated magnetic flux can be used as efficiently as possible to generate electricity efficiently.

[0050] Furthermore, the permanent magnets 36 provided on the disk 33 are arranged such that the opposing magnetic poles 36n and 36s of adjacent permanent magnets repel each other. Therefore, a magnetic flux can be generated in a direction substantially perpendicular to the rotation direction of the permanent magnet 36, and the special transformer 50 provided in the detachable stator mechanism 40 is arranged in the direction in which the magnetic flux is generated, so that electricity can be generated efficiently.

[0051] Furthermore, the main body frame 11 includes an outer peripheral member 61 that surrounds the outer periphery of the disk 33 and a plurality of outer peripheral transformers 60 that are provided at positions facing the outer peripheral surface of the disk 33 of the outer peripheral member 61 and generate electricity due to changes in magnetic flux. Therefore, electricity can be generated by the outer peripheral transformers 60 arranged on the outer periphery of the disk 33, and the apparatus as a whole can generate electricity efficiently.

[0052] In the embodiment, the special transformer 50 is not provided with a core, but the present invention is not limited to this, and a core may be provided in the special transformer 50. Further, the electric circuit in the lock plate 41 may be in any form as long as it can be energized. Also, the circuit configuration of the special transformer 50 may be any configuration as long as it can generate electricity.

[0053] That is, as long as the functions and effects of the present invention are achieved, the present invention is not limited to the embodiments.
