  As shown in FIG. 1, the embodiment of the power generation device of the present invention includes a power generation structure 10, a magnetic auxiliary drive mechanism 20, an outer shell member 30, an auxiliary drive unit 40, and a battery 50.

  As shown in FIGS. 1 and 2, the power generation structure 10 includes a stator 11 and a rotor 12, and the rotor 12 rotates with respect to the stator 11 and includes a mandrel 121.

According to this configuration, when the rotor rotates with respect to the stator, the coil of the rotor rotates between both poles (N pole-S pole) of the permanent magnet ring of the stator. Can be generated.

  In the present embodiment, the magnetic auxiliary drive mechanism 20 includes an external permanent magnetic member 21 and an internal permanent magnetic member 22, and the magnetic force of the external permanent magnetic member 21 is preferably larger than that of the internal permanent magnetic member 22.

A rotating space 210 is formed, and each of the plurality of external permanent magnets 212 is arranged on the fixed seat 211 such that the same magnetic pole faces the fixed seat 211. The internal permanent magnetic member 22 is rotatably disposed in the rotation space 210 of the fixed seat 211 and is connected so as to be interlocked with the core shaft 121 of the rotor 12 of the power generation structure 10. The internal permanent magnet 222 is provided.

  The plurality of internal permanent magnets 222 are arranged on the outer peripheral surface of the rotary seat 221, and the magnetic poles that face the outside are the same as the magnetic poles that face the rotation space 210 of the external permanent magnet 212. And the external permanent magnetic member 21 can generate a repulsive force in a direction away from the center of the rotor 12. The number of external permanent magnets 212 installed on the peripheral wall of the rotating space 210 of the external permanent magnetic member 21 is preferably smaller than the number of internal permanent magnets 222 installed on the outer peripheral surface of the internal permanent magnetic member 22. .

  As shown in FIGS. 1 to 3, in the present embodiment, the plurality of internal permanent magnets 222 are fitted into the outer peripheral surface of the rotating seat 221 obliquely in the clockwise direction with respect to the rotor 12 of the power generation structure 10. At the same time, the plurality of external permanent magnets 212 are fitted into the peripheral wall of the rotation space 210 of the fixed seat 211 obliquely in the clockwise direction of the rotor 12 of the power generation structure 10.

  Among them, an external permanent magnet center line C1 is defined in the external permanent magnet 212, and an intermediate point P1 is defined in the center of the external permanent magnet center line C1. There is a depression angle θ1 of 30 to 60 degrees between the center and the connecting line L1 from the center to the intermediate point P1 of the outer permanent magnet center line C1, and the inner permanent magnet center line C2 is defined in the inner permanent magnet 222. In addition, an intermediate point P2 is defined at the center of the inner permanent magnet center line C2, and between the inner permanent magnet center line C2 and the center point P2 of the inner permanent magnet center line C2 from the center of the mandrel 121, The depression angle θ2 is 30 to 60 degrees. The depression angle θ1 and depression angle θ2 are preferably 45 degrees.

  As shown in FIG. 1, the outer shell member 30 is a hollow member, one end of which is fixed to the stator 11 of the power generation structure 10, and the core shaft 121 of the rotor 12 of the power generation structure 10 is penetrated. .

  As shown in FIG. 1, the auxiliary drive unit 40 is installed inside the outer shell member 30 so as to be connected to the core shaft 121 of the rotor 12 of the power generation structure 10, and includes a motor 41 and a transmission gear unit 42. The motor 41 is fixed to the inner wall of the outer shell member 30 and includes a drive shaft. The transmission gear unit 42 is disposed between the core shaft 121 of the rotor 12 of the power generation structure 10 and the drive shaft of the motor 41. It is connected to. The transmission gear unit 42 in the present embodiment is a helical gear.

  As shown in FIG. 1, the battery 50 is installed inside the outer shell member 30 and is electrically connected to the motor 41 of the power generation structure 10 and the auxiliary drive unit 40 to store electric power generated from the power generation structure 10. Electric power is output to the motor 41.

  When using the power generation mounting described above, as shown in FIGS. 1 and 4, the core shaft 121 of the power generation structure 10 is directly or indirectly connected to the drive structure. The drive structure may be any drive device such as a wind drive device or a hydraulic drive device, but preferably uses natural energy such as a wind device or a hydraulic device. That is, if a force that rotates the power generation structure 10 of the power generation device is generated by a drive structure that uses natural energy, ecology and energy saving can be achieved. Further, if the rotational force of the drive structure from the outside is large, the drive structure directly drives and rotates the rotor 12 of the power generation structure 10. On the other hand, if the rotational force of the drive structure from the outside is insufficient, the motor 41 of the auxiliary drive unit 40 is driven to apply the auxiliary rotational force to the rotor 12 of the power generation structure 10 via the transmission gear unit 42, and the rotor. When the rotor 12 is rotated normally, the rotor 12 can be rotated only by an external rotational force without generating an auxiliary rotational force from the auxiliary drive unit 40. Further, when the rotational speed of the rotor 12 is slowed down, the motor 41 of the auxiliary drive unit 40 is driven once again to give an auxiliary rotational force to the rotor 12.

  When the rotor 12 of the power generation structure 10 is rotated, the magnetic auxiliary drive is mainly performed by using the repulsive force generated by the diamagnetism between the internal permanent magnetic member 22 and the external permanent magnetic member 21 of the magnetic auxiliary drive mechanism 20. While supporting the weight of the internal permanent magnetic member 22 connected to the core shaft 121 of the rotor 12 of the mechanism 20, the rotational load on the core shaft 121 of the rotor 12 of the power generation structure 10 is reduced, and the rotor 12 is supplemented. Provide a rotor. According to this configuration, the rotor 12 of the power generation structure 10 can be rotated with a rotational force that is smaller than the force that is simply rotated by driving the rotor 12 of the power generation structure 10.

  Since the external permanent magnetic member 21 and the internal permanent magnetic member 22 of the magnetic auxiliary drive mechanism 20 in the present embodiment are respectively installed obliquely along the clockwise direction with respect to the rotor 12, the external permanent magnetic member 21 and the internal permanent magnetic member 22 A repulsive force generated by diamagnetism with the permanent magnetic member 22 generates torque in a direction away from the core 121 of the rotor 12. According to this configuration, the external torque that rotates the rotor 12 of the power generation structure 10 is smaller than the torque that rotates the rotor 12 of the power generation structure 10. That is, if the repulsive force generated by the diamagnetism of the magnetic auxiliary drive mechanism 20 is used, the rotor 12 of the power generation structure 10 can be simply rotated to generate electric power with a small force.

  As shown in FIG. 5, in another embodiment of the power generation device of the present invention, a heat exhaust fan 60 is further included, and the heat exhaust fan 60 is provided inside the outer shell member 30 so as to be electrically connected to the battery 50. It can be installed and the heat of the power generation structure 10 can be released by flowing an air flow, or the heat of the motor 41 of the power generation structure 10 and the auxiliary drive unit 40 can be discharged by flowing an air flow.

  In the embodiment of the power generation apparatus shown in FIG. 5, the turbine ventilator 70 is provided outside the outer shell member 30 so as to be connected to the core shaft 121 of the rotor 12 of the power generation structure 10. Since it is driven by wind power, the rotor 12 of the power generation structure 10 is driven and rotated using wind power.

  As described above, the power generator of the present invention generates a repulsive force in a direction away from the core 121 of the rotor 12 due to the diamagnetism between the external permanent magnetic member 21 and the internal permanent magnetic member 22 of the magnetic auxiliary drive mechanism 20. Therefore, the weight of the internal permanent magnetic member 22 connected to the core shaft 121 of the rotor 12 of the magnetic auxiliary drive mechanism 20 is supported, and the rotational load of the core shaft 121 of the rotor 12 of the power generation structure 10 is reduced and rotated. Since the auxiliary torque is provided to the child 12, the rotor 12 of the power generation structure 10 can be easily rotated and the electric power generated from the power generation structure 10 can be stored in the battery 50.

  Moreover, since the electric power generating apparatus of this invention has the auxiliary drive unit 40, when driving the rotor 12 of the electric power generation structure 10, or when the rotational force is insufficient even if the rotor 12 is rotated, the rotor An auxiliary rotational force can be applied to 12.

  Furthermore, since the external permanent magnetic member 21 and the internal permanent magnetic member 22 of the magnetic auxiliary drive mechanism 20 are respectively installed obliquely along the clockwise direction with respect to the rotor 12, the external permanent magnetic member 21 and the internal permanent magnetic member 22 are installed. A repulsive force generated by diamagnetism with the magnetic member 22 generates torque in a direction away from the core 121 of the rotor 12. According to this configuration, the rotor 12 of the power generation structure 10 can be easily rotated with a small driving force, so that the force can be efficiently exchanged for electric power.
