  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The present invention combines a generator using a photothermal magnetic motor that utilizes the principle that magnetism disappears above the Curie temperature using clean solar heat that is friendly to the global environment and a clean wind generator that is also friendly to the global environment. A hybrid generator is provided.

First, the principle of the photothermal magnetic motor used in the present invention will be described. Details of this photothermal magnetic motor are described in Japanese Patent Application Laid-Open No. 2002-204588. 1 and 2 show a basic configuration of a photothermal magnetic motor using a temperature-sensitive magnetic material, FIG. 1 is a plan view of the photothermal magnetic motor, and FIG. 2 is a cross-sectional view.
A plurality of chips 1 of temperature-sensitive magnetic material made of NiAl alloy are equidistantly arranged on one surface of a disk-like support plate 4 made of ceramic, etc., which is nonmagnetic and has low thermal conductivity, in the rotation direction of the support plate 4. Are fixed as multipoles. The surface (light receiving surface) of the chip 1 is coated with a black body material for efficient absorption of heat energy of light. The black body material is formed, for example, by applying a heat-resistant resin mixed with carbon black.

  The support plate 4 is a rotating disk with a rotating shaft 5 and a bearing 7 in the center. A permanent magnet 2 is disposed on the side of the support plate 4, and the permanent magnet 2 has one pole and is fixed to the upper surface of a fixed plate 6 made of a nonmagnetic aluminum alloy, magnesium alloy or the like. In order to change the magnetic characteristics of the chip 1 due to the temperature rise, a light heat source such as laser light or sunlight is used, the light heat source is condensed by the lens 8, and the surface of the chip 1 (displaced from the magnetization center by the permanent magnet 2). (Light position) is irradiated with light (heat).

FIG. 3 is a diagram showing the rotational driving principle of this photothermal magnetic motor, and the ambient temperature is set to substantially room temperature below the Curie temperature. A tip 1 of a temperature-sensitive magnetic material, which is a nearby soft magnetic material, is magnetized and held in balance as shown in FIG. 1 by a magnetic field 9 (see FIG. 2) generated from the permanent magnet 2 before irradiation with sunlight or the like.
Here, the spot 1a indicated by the white circle in FIG. 3 (position shifted from the center of magnetization by the permanent magnet 2) is irradiated with light such as solar heat and laser on the chip 1a, and the spot 3a on the chip 1a is heated, The magnetization of the part decreases.

The spot 3a of the chip 1a is heated and the magnetic balance in the chip 1a is lost due to the local temperature rise, and the part of the chip 1a where the temperature rise is delayed is attracted to the magnetic field 9 of the permanent magnet 2 and starts rotating in the direction of the arrow. To do. Then, the entire chip 1a immediately rises in temperature, and the adjacent chip 1b is attracted to the magnetic field 9 of the permanent magnet 2 to accelerate the rotation. By repeating this, a continuous rotational force can be obtained.
While the chip 1 is rotated again to return to the original position, it is naturally cooled, the temperature of the chip 1 is lowered, and the magnetic characteristics are improved. Continuous rotation is maintained by these series of heating and cooling.

  In this principle, when the rotation is reversed, the light irradiation position is shifted to 3b in FIG. 3 to rotate counterclockwise in the drawing.

  Next, the configuration of the present invention will be described in detail. FIG. 4 shows a configuration diagram of a hybrid power generation apparatus A that combines solar heat and wind power.

And a wind power generation unit 31 that performs clean power generation using natural wind power.

  In order to use the heat source that condenses and heats the solar heat, the photothermal magnetic power generation unit 11 condenses the acrylic Fresnel lens 12 for condensing the solar heat and the solar heat effectively and reliably. A tracking device 13 that tracks the Fresnel lens 12 toward the sun, a condensing heat plate 14 that is disposed on the focal side of the Fresnel lens 12 so as to be movable in the focal direction, and that receives condensed heat from the Fresnel lens 12; A plurality of quartz optical fibers 16 whose one ends are arranged on the condensing heat plate 14 side, and a magnetic rotating disk 18 which is opposed to the other end side of the optical fibers 16 and is rotatable integrally with a rotating shaft 17. The surface of the magnetic rotating disk 18 is constituted by a support 15 or the like facing the surface at a predetermined interval.

FIG. 5 shows a broken plan view of the magnetic turntable 18 and the support 15, the right side shows the magnetic turntable 18, and the left side shows the support 15. As shown in FIG. 6, the central portion of the magnetic rotating disk 18 and the base of the rotating shaft 17 are integrated, and the magnetic rotating disk 18 is rotatable about the rotating shaft 17.
The support 15 is disposed on the rotary shaft 17 via a bearing 21, and the support 15 is fixed to a casing or the like at another location. That is, the support body 15 is fixed, and the rotary shaft 17 is inserted into the bearing 21 of the support body 15 so that the magnetic rotating disk 18 and the rotary shaft 17 are rotatable with respect to the support body 15.

The magnetic rotating disk 18 and the support 15 have substantially the same diameter, and six permanent magnets 22 are provided on the periphery of the support 15 made of a nonmagnetic material in the present embodiment. In this embodiment, the chip 20 made of a temperature-sensitive magnetic material and the permanent magnet 22 are arranged in parallel. The permanent magnet 22 is magnetized in the thickness direction and is equidistantly arranged on the peripheral edge of the support 15. Six permanent magnets 22 are fixedly arranged.
Although the permanent magnet 22 is provided on the upper surface (direction in FIG. 6) of the support 15, the support 15 is provided with a notch, and the permanent magnet 22 is embedded in the notch so that the permanent magnet 22 The upper surface and the upper surface of the support 15 may be flush with each other.

  Further, the other end of the optical fiber 16 is also arranged at equal intervals on the periphery of the magnetic rotating disk 18, and the other end of the optical fiber 16 is located at a position corresponding to the position of the permanent magnet 22. The tip 20 is irradiated from the other end.

Further, the magnetic rotating disk 18 is made of a non-magnetic and low thermal conductivity material such as ceramics, and the upper surface of the chip 20 made of the temperature-sensitive magnetic material fixedly disposed on the magnetic rotating disk 18 is black. Body material is coated on the light-receiving surface.
As shown in FIG. 6, since the chip 20 and the permanent magnet 22 are arranged in parallel, a magnetic field 23 as shown by an arrow is generated.

  Further, as shown in FIG. 6, the other end of the optical fiber 16 is close to or in contact with the surface of the chip 20, and the surface of the chip 20 is irradiated with solar heat from the end face of the coating. The heat source condensed and heated by the Fresnel lens 12 and the condensing heat plate 14 by the optical fiber 16 is surely and safely guided to the chip 20 as a target place without loss.

  Further, the solar heat guided from the optical fiber 16 is made to have a plurality of symmetrical spots 20 (similar to the spot 3a in FIG. 3) of the magnetic rotating disk 18 at or above the Curie temperature, and the magnetism of these spots is turned off. The magnetic rotating disk 18 is rotated, the coil is rotated by this rotational force, and electric power is generated.

  As shown in FIG. 4, the wind power generation unit 31 includes an impeller 32 that rotates by receiving wind force, a rotation converter 34 that changes the rotation direction of the shaft 33 of the impeller 32, and a shaft 35 of the rotation converter 34. The rotation converter 36 transmits the rotation direction to the rotation shaft 37, and the outer cylinder 38 rotates integrally with the rotation shaft 37.

The rotating shaft 17 of the photothermal magnetic power generation unit 11 is located in the outer cylinder 38, and this portion is referred to as a power generation unit 40. FIG. 7 shows an enlarged cross-sectional view of a main part of the power generation unit 40, and the configuration of the power generation unit 40 is, for example, the same as that of a synchronous generator.
A rotor 41 is fixed to the rotating shaft 17 of the magnetic rotating disk 18, and a magnetic flux generating means 42 composed of a permanent magnet or a field winding is provided on the outer periphery of the rotor 41.

On the other hand, a stator 43 is provided on the inner peripheral surface of the cylindrical outer cylinder 38 on the wind power generation unit 31 side, and a slight gap is formed between the outer peripheral surface of the magnetic flux generating means 42 on the inner peripheral surface of the stator 43. The armature windings 44 are arranged so as to face each other.
As the rotating shaft 17 rotates, power is generated by inducing a voltage in the armature winding 44 by a rotating magnetic field formed by the magnetic flux generating means 42.

Here, when the impeller 32 is not rotating, such as when there is no wind, and when the daytime sun is coming out, the sunlight heat is condensed by the Fresnel lens 12, and the condensed heat from the optical fiber 16 is collected. Irradiates the chip 1 of the magnetic rotating disk 18, and the magnetic rotating disk 18 rotates on the principle described above.
When the magnetic rotating disk 18 rotates, power is generated by inducing a voltage in the armature winding 44 by the rotating magnetic field formed by the magnetic flux generating means 42 of the rotating shaft 17. In this case, the outer cylinder 38 on the wind power generation unit 31 side of the power generation unit 40 does not rotate.

  Next, when there is wind at night and the impeller 32 is rotating, the outer cylinder 38 is rotated by rotating the rotating shaft 37 on the wind power generation unit 31 side. In this case, the rotating shaft 17 on the photothermal magnetic power generation unit 11 side does not rotate, but the armature winding 44 of the outer cylinder 38 rotates, so that the voltage is applied to the armature by the rotating magnetic field relatively formed by the magnetic flux generating means 42. Electric power is generated by induction in the winding 44.

  Further, when there is a wind and the impeller 32 is rotating and in the daytime, the rotating shaft 17 on the photothermal magnetic power generation unit 11 side and the outer cylinder 38 on the wind power generation unit 31 side are also rotated simultaneously. become. Here, the rotation direction of the rotating shaft 17 on the photothermal magnetic power generation unit 11 side is opposite to the rotation direction of the rotation shaft 37 (outer cylinder 38) on the wind power generation unit 31 side. The total number of rotations of the shaft 17 and the rotating shaft 37 is achieved, and the power generation efficiency in the armature winding 44 can be increased.

  Moreover, when raising the temperature irradiated to the chip | tip 1 of the magnetic rotating disk 18, it can carry out easily by moving either the said condensing heat plate 14 or the Fresnel lens 12 to a condensing direction. In such a case, it can be used when the Curie temperature is high due to the material of the chip 1 and can be dealt with regardless of the temperature-sensitive magnetic material used to form the chip 1.

As described above, in the present invention, the hybrid thermoelectric generator A is formed by combining the photothermal magnetic power generation unit 11 using solar heat and the wind power generation unit 31 using wind power. Power generation is possible, and it is possible to generate power if there is a wind or in the daytime, especially in the case of fine weather. Can do.
In addition, because it can generate electricity without using any fossil fuels, it can effectively, reliably, efficiently, and safely use heat sources and wind power that concentrates clean solar heat that is friendly to the global environment. It is something that can be done.

  Moreover, since the rotation direction of the rotating shaft 17 of the photothermal magnetic power generation unit 11 and the rotation shaft 37 of the wind power generation unit 31 are opposite to each other, power generation efficiency can be increased. Furthermore, since the Fresnel lens 12 always tracks the sun by the tracking device 13, the solar heat can be effectively and reliably condensed and heat generation efficiency can be improved.
