(Embodiment)
A generator according to an embodiment of the present invention will be described with reference to the drawings. The generator 1 shown in FIG. 1 is a device for outputting generated power to the outside, and is characterized in that a power source for power generation operates based on power generated by itself.

First, the structure of the generator according to the present embodiment will be described with reference to the drawings. As shown in FIG. 1, the generator 1 has a shell 2 having a bottomed cylindrical base 2 a and a cover 2 b fitted to the base 2 a. The outer structure 2 is formed by, for example, metal molding or resin molding using a mold.

Inside the outer structure 2, a power generation coil 3, a rotating plate 4, a first permanent magnet 5, a second permanent magnet 6, an induction coil 7, a main power storage unit 8, a sub power storage unit 9, Is configured to be accommodated.

The power generating coil 3 is composed of, for example, a plurality, and has a U-shaped vertical section, and is arranged concentrically along the inner surface of the base portion 2a so that the U-shaped opening surface 3a faces inward. As a result, they are arranged in an annular shape when viewed from above. In the power generating coil 3, a winding 3b such as a copper wire is wound around an outer peripheral surface of a magnetic core such as iron. With this magnetic core, the change in the magnetic field can be increased to increase the induced electromotive force (power generation). The magnetic core is desirably a soft magnetic material such as iron. If the core is a soft magnetic material, the magnetic flux generated by the coil increases. For example, the core material is iron, pure iron, an iron-based alloy, ferrite, permalloy, silicon steel, an amorphous magnetic alloy, sendust, or the like. The higher the permeability of the material, the higher the magnetic flux density in the coil.

The rotating plate 4 is an annular plate whose outer edge is inserted into the U-shaped opening space 3 a of the power generation coil 3. The rotating plate 4 has a compact structure that floats and rotates as shown in FIG. 2B, and has no mechanical contact during power generation. Therefore, there is no contact loss and vibration noise can be reduced. The outer edge of the rotating plate 4 may be expanded and contracted by centrifugal force.

The first permanent magnet 5 is mounted on the outer edge side of the rotating plate 4 and has an annular shape when viewed from above. The direction of the magnetic field of the first permanent magnet 5 is, for example, a vertical (up-down) direction, and a plurality of permanent magnets are arranged so as to form a magnetic field in various patterns such that the direction of NS and the direction of SN change alternately. . The second permanent magnet 6 is mounted on the inner edge side of the rotating plate 4 and has an annular shape when viewed from above.

Inverter unit 11 is arranged between main power storage unit 8 and induction coil 7, and controls a current flowing from sub power storage unit 9 to induction coil 7 based on the amount of power measured by power measurement unit 10. Thus, the rotation amount of the rotating plate 4 is controlled.

An electric current is generated by generating an induced current in the coil 3. In this case, the relationship between the magnet (magnetic force), the force (rotation) and the electricity (current) is established such that the so-called Fleming's right-hand rule is established, and the first permanent magnet 5 in the opening space 3a of the power generation coil 3 is formed. Is rotated to change the magnetic field (magnetic flux density) of each of the plurality of power generation coils 3, and power is output from each power generation coil 3.

As shown in FIG. 4, the power measuring device 10 is provided on the output side of the power generation coil 3 and measures the power of the circuit using, for example, a current transformer (CT: Current @ Transformer) 10a. When measuring the power of the circuit, for example, a current transformer 10a is used, and generally, a power measuring unit 10 is connected to a receiving circuit of the current transformer 10a. The power measurement unit 10 performs a power calculation by inserting a burden resistor 10b into a circuit connected to the current transformer 10a, detecting a voltage across the burden resistor 10b, measuring a current value, and performing power computation.

Here, the functional configuration of the power measuring unit 10 will be described.

(5) As shown in FIG. 5, the inverter unit 11 includes a power amount receiving unit 11a and a control unit 11b. The power amount receiving unit 11a receives the measured power value from the power measuring device 10 as a signal. Control unit 11b adjusts the output current flowing from sub power storage unit 9 to induction coil 7 according to the measured power value received by power amount receiving unit 11a. Thus, power generation is performed by controlling the rotation amount of the rotating plate 4 in accordance with the power consumption amount of the generator 1. The control in the inverter unit 11 may be realized by an analog circuit or by software control.

Next, the structure of the power generation coil 3 will be described with reference to FIG.

A U-shaped plate member as shown in FIG. 6B may be provided concentrically. The output of the winding 3b is both ends of the winding 3b of the plurality of power generation coils 3 connected in series. Then, for example, an alternating current generated by the power generation coil 3 flows through the winding 3b to a rectifying unit (such as a diode or a thyristor) and is rectified into a DC current. The power is distributed to the power storage unit 9 and can be stored. In addition, the winding method of the power generation coil 3 is various and is not limited to this example.

The generator 1 operates on the power generated by itself, does not require an external energy source, and can be a clean next-generation generator with energy-saving distributed generation that continues to generate semi-permanently. That is, the power generated by the generator 1 is supplied to the sub power storage unit 9 by the power generated by itself, and the power is used to rotate the rotating plate 4 to repeat semi-permanent stable power generation. Further, the power measuring unit 10 can grasp the integrated power amount and sense the voltage / current, and the inverter unit 11 can control the rotation speed of the rotating plate 4 to use the driving power in accordance with the power consumption.

As a result, it is possible to contribute to the achievement of the basic energy policy of 3E (resource self-sufficiency rate, electricity cost, greenhouse gas emissions) + S (safety). Furthermore, variations can be provided according to various purposes (detached houses, condominiums, commercial buildings, each community in each prefecture, vehicles, ships, etc.). In addition to the construction, operation, and maintenance, it can contribute to regional revitalization (industrial promotion, environmental education, etc.) triggered by a logistics-based supply chain, including after-generator services.

And a stator 25 disposed at The radius of the rotating blade 23 is, for example, 560 mm. The winding system of the stator 25 is, for example, a concentrated winding, and is supplied with a current from a lead wire (not shown) to have magnetism corresponding to the magnitude of the current.

The rotating blade 23 includes, on its upper and lower surfaces, a floating permanent magnet 26 for rotating the rotating blade 23 while floating, and a power generating permanent magnet 27 disposed at a position adjacent to the power generating coil 24. In addition, a rotating permanent magnet 28 for rotating the rotating blade 23 by repelling the dielectric coil (dielectric) of the stator 25 is provided on the outer side surface. Here, the permanent magnet is an object that keeps its properties as a magnet for a relatively long time without being supplied with a magnetic field or current from the outside, and is, for example, an alnico magnet, a ferrite magnet, a neodymium magnet, or the like.

The base portion 21 a and the cover portion 21 b of the outer structure 21 have a repulsive permanent magnet 29 that repels the floating permanent magnet 26 at a position facing the floating permanent magnet 26 of the rotating blade 23.

Here, the floating rotation structure of the rotary blade 23 will be described with reference to FIGS. As shown in FIG. 12, the rotating blade 23 has a pair of mountain slopes 30 inclined from the outside toward the inside at the inner edges of the upper and lower surfaces, and the floating permanent magnet 26 It is arranged on the surface of the surface 30. The base portion 21a and the cover portion 21b shown in FIG. 11 have a valley slope 31 that slopes from the inside to the outside at a position facing the pair of mountain slopes 30. , On the surface of the valley slope 31. The mountain slope 30 and the valley slope 31 have the same slope angle as shown in FIG. 11C, and the slope angle is in a range of 25 to 30 degrees, for example. The angle of inclination is appropriately changed according to the size and weight of the rotary blade 23 and the arrangement, number, shape, and repulsion of the floating permanent magnets 26 and repulsive permanent magnets 29.

The closer the gap between the power generating permanent magnet 27 and the power generating coil 24, the more preferable.

The rotation of the rotary blade 23 rotates the power generation permanent magnet 27 at a position adjacent to the power generation coil 24, and changes the magnetic field of each of the windings wound around the power generation coil 24 to generate power. The generated power is supplied from the supplied power supply plug 24a. Generator 20 further stores a main power storage unit (not shown) that stores power generated by power generation coil 24, and power generated by power generation coil 24, similarly to the first embodiment.
