[0017] The present invention will be described in more detail below using preferred embodiments, but the following embodiments are merely examples of realizing the present invention and the present invention is not limited thereto.

[0018] Figures 1 to 12 show one embodiment of the power generating device of the present invention. As shown in Figures 1, 2, 3, and 4, the power generating device 1 according to this embodiment includes a rotor 3 that can rotate around a rotation axis 2, an outer frame 4, a first magnet 5 fixed to the rotor, a second magnet 6 supported by the outer frame 4, and a coil 7 arranged in the outer frame 4.

[0019] The power generating device 1 of this embodiment is a power generating system that generates electricity by utilizing electromagnetic induction caused by changes in magnetic flux in the coil 7 on the outer frame 4 side as a result of the rotation of the rotor 3 and its first magnet, thereby generating an induced current (induced electromotive force) in the coil 7. Furthermore, as shown in Figures 9 and 10, the power generating device 1 rotates the rotor 3 about the rotation axis 2 by the auxiliary rotation device 10, and then reduces or cuts off (or stops) the rotational driving force of the auxiliary rotation device 10, and generates electricity by electromagnetic induction by the first magnet and coil 7 in the same manner as above, as the rotor 3 rotates due to the inertial force of the rotor 3 itself in which rotational energy has been accumulated, and the magnetic action of the first magnet 5 and the second magnet 6.

[0020] The rotating body 3 is a rotating body that rotates around the rotating shaft 2. In this embodiment, as shown in Figures 2, 6, 7, and 8, the rotating body 3 is fixed to the rotating shaft 2 and rotates integrally with the rotating shaft 2.

[0021] The rotating shaft 2 is made of, for example, a steel pipe or the like, and is formed into a cylindrical shape with a predetermined length. A rotor 3 is fixed to a midpoint along the axis of the rotating shaft 2. The rotating shaft 2 is rotatably supported by an outer frame 4, for example, with its longitudinal direction oriented horizontally.

[0022] The rotor 3 has an overall contour formed into a cylindrical shape with a relatively short axial length, for example. The rotor 3 has the rotating shaft 2 penetrating its center with their central axes aligned, and both ends of the rotating shaft 2 are fixed in a state of protruding outward from the rotor 3. Therefore, the rotor 3 is installed with the cylindrical central axis oriented horizontally,

[0023] The rotating body 3 is, for example, arranged with a plurality of radial frames 31 extending radially from the rotating shaft 2, and a polygonal frame 32 is fixed to connect the tips of adjacent radial frames 31. Units combining these radial frames 31 and polygonal frames 32 are arranged in pairs at a predetermined interval and fixed to the rotating shaft 2. A cross frame 33 is provided to connect the extended tip sides of each radial frame 31.

[0024] The rotating body 3 has a cylindrical body 34 fixed to the radial frame 31, polygonal frame 32, and horizontal frame 33 in the circumferential direction. Furthermore, both end sides in the direction along the rotating axis 2 are provided so as to be partially closed by doughnut-shaped side end portions 35 that are open in the center.

[0025] The rotating body 3, for example, including the radial frame 31, polygonal frame 32, and horizontal frame 33, as well as the body 34 and side end portions 35, are made of a high-strength metal such as iron or stainless steel. Therefore, the rotating body 3 as a whole is fairly heavy and has a relatively large moment of inertia. As a result, when the rotating body 3 is rotationally driven by the auxiliary rotation device 10, it can store a large amount of rotational energy, and when the auxiliary rotation device 10 is cut, it can release a large amount of rotational energy.

[0026] The first magnet 5 is a magnetic element that is fixed to the rotor 3, rotates integrally with the rotor 3, and generates electricity in cooperation with the coil 7 on the outer frame. In this embodiment, the first magnet 5 is made of a permanent magnet such as a neodymium magnet, and is fixed to the entire outer surface of the body 34 of the rotor 3, which is formed in a cylindrical shape.

[0027] The first magnet 5 is fixed to the rotating body 3, rotates integrally with the rotating body 3, and is a magnetic element that generates electricity in cooperation with the coil 7 of the outer frame 4. Furthermore, the first magnet 5 also serves as a magnetic element that cooperates with the second magnet 6 of the outer frame 4 to assist or maintain the rotation of the rotating body 3.

[0028] In this embodiment, the first magnet 5 is made of a permanent magnet such as a neodymium magnet, and is fixed to the entire outer surface of the body 34 of the rotating body 3 which is formed in a cylindrical shape.

[0029] The first magnet 5 is arranged with one magnetic pole facing radially outward. More specifically, the first magnet 5 is made up of a plurality of magnet members, and is arranged on the outer surface of the barrel 34 of the rotor 3 with N poles and S poles alternately arranged in the circumferential direction.

[0030] The outer frame 4 is a support means provided to rotatably surround the periphery of the rotor 3. In this embodiment, the outer frame 4 is a magnet support means that supports the second magnets 6 in a predetermined arrangement around the periphery of the rotor 3. At the same time, the outer frame 4 also functions as a support means that rotatably supports the rotating shaft 2.

[0031] As shown in Figures 1, 3, 4, and 5, the outer frame 4 is formed of a metal such as iron, and has a cylindrical cover body 41 formed in the shape of a hollow cylinder large enough to form a hollow space capable of accommodating the rotating body 3 inside, and a base 42 for stably supporting the cylindrical cover body 41.

[0032] The cylindrical cover body 41 has a body portion 411 having a diameter approximately one size larger than that of the rotating body 3, and a disk-shaped side wall portion 412 large enough to close both ends of the body wall portion 411 in the direction along the central axis.

[0033] The cylindrical cover body 41 has an internal space that is formed in a substantially closed shape to accommodate the rotating body 3. This makes it possible for the rotating body 3 inside the cylindrical cover body 41 to be less susceptible to the effects of, for example, wind, excess air resistance, dust, etc., and to stably maintain the rotation of the rotating body 3.

[0034] A plurality of second magnets 6 are supported on the body wall 411 of the cylindrical cover body 41 of the outer frame 4. Furthermore, the rotating shaft 2 is supported at the center position of the side wall 412 of the cylindrical cover body 41 of the outer frame 4 while passing through it.

[0035] Support bodies (circumferential horizontal bars) that are elongated in the direction along the rotation axis 2 and are arranged at equal intervals in the circumferential direction are fixed to the body wall portion 411 of the cylindrical cover body 41.

[0036] The side wall 412 of the cylindrical cover 41 is provided with a plurality of through holes 413 that are drilled so as to penetrate the plate surface of the side wall 412. These through holes 413 are configured to communicate between the outside and the inside of the cylindrical cover 41. This facilitates the release of heat generated by the rotation of the rotor 3 in the substantially closed internal space of the cylindrical cover 41, thereby preventing a rise in temperature. The through holes 413 may be oriented in a direction and sized so as not to affect the rotation of the rotor 3, and the number and positions of the through holes 413 may be arbitrary.

[0037] A reinforcing member 414 is integrally provided on the side wall portion 412 of the cylindrical cover body 41. The reinforcing member 414 includes, for example, a disk-shaped hub portion that reinforces the periphery of the center portion that supports the rotating shaft 2, and a plurality of reinforcing frame portions that extend radially from the hub portion to the outer edge of the side wall portion 412.

[0038] The base 42 has, for example, a lower frame portion 42a for installation on the ground or floor, and a cover body receiving portion 42b that fits over the arc edge on the lower side of the side wall portion 412 of the cylindrical cover body 41.

[0039] The lower frame portion 42a is formed into a substantially rectangular parallelepiped shape by combining frame members such as metal H-shaped steel, and reinforcing frame members are fixed to each side surface in a diagonal manner.

[0040] The cover body receiving portion 42b has plate pieces arranged at the four corners of the lower frame portion 42a, and supports the cylindrical cover body 41 with an arc-shaped portion corresponding to the arc of the side wall portion 412 of the cylindrical cover body 41.

[0041] The second magnets 6 are supported by the outer frame 4 and arranged to face the first magnets 5, and a plurality of second magnets 6 are arranged circumferentially around the outside of the rotating body 3, and are magnetic elements that cooperate with the first magnets 5 to assist the rotation of the rotating body 3. Each second magnet 6 has, for example, a rod-shaped portion 61 on one end facing the first magnet 5, where either a north pole or a south pole is formed.

[0042] The rod-shaped portion 61 of the second magnet 6 is arranged radially around the rotating shaft 2, with one end of either the north or south pole facing the first magnet side of the rotating body 3, and is supported in a penetrating manner by the body wall portion 411 of the cylindrical cover body 41 of the outer frame 4.

[0043] The second magnets 6 are arranged so that the ends facing the first magnets 5 along the circumferential direction have alternating north and south poles. This is expected to effectively assist the rotation of the rotating body 3 due to magnetic attraction or repulsion between the first magnets 5 configured as described above and the second magnets 6 with alternating north and south poles.

[0044] 12, the second magnet 6 has a horizontal bar integrally formed on the end of the rod-shaped portion 61 facing the first magnet 5, which crosses the rod-shaped portion 61 in a T-shape. That is, in this embodiment, the second magnet 6 is formed in a roughly T-shape, with the horizontal bar of the T facing the first magnet 5 and the vertical bar of the T supported by the outer frame 4. Therefore, the horizontal bar formed on the side of the second magnet 6 facing the first magnet forms an enlarged portion 62 that is provided to expand the end area of ​​the rod-shaped portion 61. The enlarged portion 62 ensures a relatively large area for the magnetic pole of the second magnet facing the first magnet 5, thereby improving the efficiency of magnetic force action that contributes to rotation assistance.

[0045] Note that the second magnet 6 may have, for example, only the expanded portion 62 as the magnet body, and the rod-shaped portion 61 formed from a non-magnetic material. Also, the expanded portion 62 of the second magnet may be formed from the rod-shaped portion 61 in an L-shape or in a plate shape.

[0046] The second magnet 6 may be configured as an electromagnet instead of a permanent magnet.

[0047] The second magnet 6 is supported with at least a portion of its rod-shaped portion 61 protruding outward from the body wall portion 411 of the cylindrical cover body 41 of the outer frame 4. Furthermore, the rod-shaped portion 61 of the second magnet 6 is supported by the body wall portion 411 of the cylindrical cover body 41 so that the magnetic pole (expanded portion 62) can be moved closer to or farther away from the first magnet 5 of the rotating body 3. This allows the magnetic force to be increased by bringing the magnetic pole of the second magnet 6 closer to the first magnet 5, and conversely, the magnetic force to be decreased by moving the magnetic pole of the second magnet 6 farther away from the first magnet 5, thereby adjusting the magnitude of the magnetic force.

[0048] Furthermore, the second magnets 6 are arranged at both end positions of the body wall 411 of the cylindrical cover body 41 of the outer frame 4, and are arranged radially along the circumferential direction at both end positions. That is, two sets (or multiple sets) of the second magnets 6 arranged radially in the circumferential direction (magnet groups) are installed facing each other at a predetermined interval in the direction along the rotation axis 2. Note that the second magnets arranged at the same angular position in the circumferential direction of the body wall 411 of the cylindrical cover body 41 and spaced apart in the direction along the rotation axis 2 have the same magnetic pole facing the first magnet 5.

[0049] The coil 7 is a power-generating coil that is circumferentially arranged on the outer frame 4 so as to generate an induced current by electromagnetic induction as the first magnet 5 of the rotor 3 rotates. In this embodiment, the coil 7 is arranged on the inner wall side of the body wall portion 411 of the cylindrical cover body 41 of the outer frame 4 so as to face the first magnet 5, as shown in FIGS.

[0050] The coil 7 is formed, for example, by being wound around the rotary shaft 2 along the body wall 411 and fixed to the body wall 411. An end of the coil 7 is drawn out from the side wall 412 of the cylindrical cover body 41 and connected to an electrical connection terminal 71. As shown in Fig. 9, the electrical connection terminal 71 is configured to supply electricity via an electric wire 72 to a secondary battery 73 that charges the power generated by the coil 7 or to an external device E.

[0051] The coil 7 may be configured, for example, by arranging a plurality of coils at predetermined intervals in the circumferential direction with their end openings facing the first magnet 5.

[0052] 2, 6, and 7, a third magnet 8 is fixed to the outer surface of the side end 35 of the rotor 3. The third magnet 8 is made of a permanent magnet such as a neodymium magnet, and is formed on the entire surface of the doughnut-shaped side end 35 of the rotor 3, with either the N pole or the S pole facing outward.

[0053] A second coil 9 is installed on the inner wall side of the side wall portion 412 of the cylindrical cover body 41 of the outer frame 4 so as to face the third magnet 8 of the rotating body 3. The second coil 9 is configured, for example, by being wound circumferentially around the rotating shaft 2, and is fixed to the side wall portion 412 of the cylindrical cover body 41.

[0054] Rotation of the third magnet 8 together with the rotor 3 causes a change in magnetic flux to the second coil 9, which generates an induced current through electromagnetic induction and can generate auxiliary electricity. An end of the second coil 9 is connected to an electrical connection terminal 71.

[0055] In this embodiment, an auxiliary rotation device 10 for driving the rotating body 3 to rotate is provided.

[0056] As shown in Figures 9, 10 and 11, the auxiliary rotating device 10 has, for example, a clutch device 101 that can be connected and disconnected to the rotating shaft 2, a hydraulic motor 102 that generates a rotational driving force that is transmitted to the rotating shaft 2 via the clutch device 101, and a geared motor 103 (for the hydraulic pressure generating device).

[0057] In this embodiment, an auxiliary rotation device 10 is connected to each end of the rotation shaft 2 protruding from both ends of the rotating body 3, so that the rotating body 3, which has a certain amount of weight, can be stably rotated.

[0058] When using the power generating device 1 according to this embodiment, first, as shown in FIGS. 3 and 9 , the clutch device 101 of the auxiliary rotation device 10 is connected to the rotating shaft 2, and the hydraulic motor 102 is driven to transmit the rotational driving force to the rotating shaft 2 via the clutch device 101. This causes the rotating body 3 to rotate around the rotating shaft 2 integrally with the rotating shaft 2. At this time, the rotation is assisted in the same direction of rotation by the magnetic force action between the first magnet 5 fixed to the rotating body 3 and the second magnet of the outer frame 4. At the same time, the magnetic flux in the coil 7 changes in accordance with the rotational displacement of the first magnet 5, which rotates integrally with the rotating body 3, and electricity is generated by electromagnetic induction.

[0059] The rotating body 3 is rotated at a predetermined rotation speed, and once rotational energy has been accumulated and sufficient inertia has been generated, the clutch device 101 of the auxiliary rotating device 10 is disengaged, stopping the rotational drive force from the auxiliary rotating device to the rotating shaft 2. This causes the rotating body 3 to rotate due to the inertial force of the rotating body 3 itself and the magnetic action between the first magnet 5 and the second magnet 6. As the first magnet 5 of the rotating body 3 rotates, the magnetic flux in the coil 7 changes, generating electricity through electromagnetic induction. In this way, by utilizing the rotational energy of the rotating body and the action of magnetic force, a power generating device with low vibration and high power generation efficiency can be realized.

[0060] The formula used to calculate the amount of power generated is shown below. The cylindrical body is made of steel plate (50 mm thick, 392.5 kg / m2). The rotating body is made of steel plate (thickness 22 mm, 172.7 kg / m2). The rotating shaft is made of STS high-pressure carbon steel pipe (nominal diameter 500, thickness 50.0 mm, 50.0 kg / m).

[0061] The magnetic force is generated by using a permanent magnet or an electromagnet. 1. Rotating magnetic force is generated by combining a permanent magnet and an electromagnet. 2. Neodymium magnets are used as permanent magnets. 3. Attach to part of the inside of a cylinder or the entire surface of a rotating body. 4 Coils are placed at both ends inside the cylinder to generate induced power. 5. The electromagnets are placed on both ends of the cylinder facing the permanent magnets. 6. Each electromagnet must be 2.6 kW or more. Permanent magnets can also be used instead of electromagnets.

[0062] The auxiliary rotation device uses a hydraulic motor or the like. The secondary battery uses 1,500kw to 1,600kw.

[0070] The environment may be adjusted to reduce the weight of the rotating body 3. For example, the space in which the rotating body 3 rotates may be made zero-gravity, improving rotation efficiency and allowing the rotating body 3 to continue rotating according to the law of inertia. In addition, air resistance may be reduced by, for example, reducing the air in the power generation device 1 by 70 to 80%. The suction capacity may be increased almost twice as much as the cooling capacity. [Explanation of symbols]
