BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power generation method and a power generation device capable of obtaining output power larger than input power when using industrial or household power.

[0002]

2. Description of the Related Art At present, household electric power including industrial electric power is mainly dependent on electric power supplied from electric power companies, and the electric power consumption is already enormous. Is expected to be widely introduced, and in household electric power, the spread of tableware dryers, washing and drying machines, water heaters, electromagnetic cookers and washing toilets and air conditioning equipment, which are also called secondary home appliances, And the supply of electric power is in a tight situation due to an increase in home care equipment. By the way, in the current power supply, an enormous amount of power is consumed over an extremely wide range, so that it is indispensable for the power generation facility to generate at least a few hundred thousand kW or more. In addition, as this power generation means, an extremely large multiplex is required. In addition, since a rotor made of a permanent magnet with a strong magnetic flux density is rotated close to a large number of magneto coils and is rotated at high speed, in order to rotate the rotor, in hydroelectric power generation, to secure a huge amount of water and head energy. It is necessary to construct a dam for the power plant, and in the case of thermal power and nuclear power generation, it is necessary to secure coal oil or fuel uranium for the generation of pressurized heated steam and to develop a storage facility and secure safe housing for power generation. With
Environmental restrictions such as noise and vibration, combustion exhaust gas, incineration ash, and hot drainage are large, so even if a temporary power generation facility is constructed, it will be limited to a depopulated area that is extremely remote from the consumption area, adding to the enormous power generation equipment cost. Therefore, the supply of new electricity is facing a serious problem due to the enormous cost of transmission equipment to the consumption area and the transmission cost.

In view of the above background, as one solution, solar power generation using solar energy has been actively attempted. However, not only is solar power generation significantly inferior in power generation efficiency, but also the sunshine duration at the installation site is reduced. At first, it is greatly affected by the weather, and since the power generation is in the daytime, a large-capacity charging facility must be attached, and when relatively large power is used like industrial power, solar power panels for power generation are also expanded. A large area is required, and there is a problem that it cannot be used in terms of equipment space in urban areas, and it is only used for household power at best. On the other hand, as a solution, although the development of so-called energy-saving and power-saving products such as low power consumption industrial equipment, home appliances and lighting equipment is being actively promoted, power factor of electric motors and The illuminance of lighting fixtures etc. still decreases, and at the present time, sufficient energy-saving and power-saving products have not been realized.

As a result of intensive studies conducted by the inventors of the present invention in order to solve such a problem, technical development in permanent magnets has advanced today, and residual magnetic flux density in alnico magnets is 1
The maximum energy product of 1.5 KG is 11.0 MGOe, and the residual magnetic flux density of samarium-cobalt magnet is 8.2 to 11.2 KG, and the maximum energy product is 16 to 32 MG.
Oe, and the residual magnetic flux density of 10.5 to 13 MG for the Nd iron magnet and 30 to 55 MGOe for the maximum energy product.
Is developed and put on the market, and by closing a permanent magnet having such a high residual magnetic flux density with a yoke made of a soft magnetic material with a high magnetic permeability, a closed magnetic path is formed in the running magnetic path, In addition, paying attention to the fact that the electromagnet can generate a magnetic force with a high magnetic flux density with a small amount of electric power and can freely change the magnetic flux direction generated by the addition direction of the current, and in a closed magnetic circuit with a high magnetic flux density by a permanent magnet. The closed magnetic circuit of the yoke is formed into an open magnetic circuit and connected by generating alternating magnetic flux in the reverse direction and in the direction of about 1 with a magnetic flux density substantially equal to the magnetic flux density of the permanent magnet with respect to the magnetic flux direction. The inventors have found that the magnetic flux density of the permanent magnet and the magnetic flux density generated by the magnetizing coil are electromagnetically induced in the soft magnetic material by a high electromagnetic induction action, and the present invention has been accomplished.

[0005]

That is, according to the present invention, an open magnetic circuit of a magnetic flux path having a high magnetic flux density held by a permanent magnet is generated by generating alternating magnetic flux with a magnetizing coil by inputting a small amount of AC power. It is to provide a power generation method and a power generation device that exert a high electromagnetic induction effect by making the magnetic pole and the closed magnetic circuit and obtain a large output power with respect to the input.

[0006]

In order to solve the above-mentioned problems, the technical means adopted by the present invention is a yoke composed of a permanent magnet magnetized to a required magnetic flux density and having a high magnetic permeability and a soft magnetic material. The magnetic flux density of the permanent magnets in the closed magnetic circuit is substantially equal to the magnetic flux density of the permanent magnets in the closed magnetic circuit, and an alternating magnetic flux is generated so as to be reverse to and in the same order as the magnetic flux direction to open or close the magnetic circuit. A magnetizing unit for providing strong electromagnetic induction is provided on one side of the yoke, and an induction yoke made of a soft magnetic material having high magnetic permeability is connected to the magnetizing unit. An appropriate number of alternating output units that have an induction coil for extracting induced power from electromagnetic induction on one side of the induction yoke are connected and closed, and the required AC power is input to the magnetizing coil and the input power is input from the induction coil. Greater than A power generation method and a power generation device for extracting various output powers, further, a power generation device including an appropriate number of magnetizing units and output units as one unit, and connecting the plurality of units in series, It exists in the configuration of the power generation device that outputs a large amount of electric power.

[0007]

The present invention has the following actions because it has the above-mentioned configuration. That is, since a yoke made of a soft magnetic material with a high magnetic susceptibility is formed sandwiching a permanent magnet magnetized to a required magnetic flux density, the magnetic flux of the permanent magnet runs in the yoke in one direction to form a closed magnetic path. At the same time as forming the magnetizing unit, a magnetizing unit is formed on one side surface of the yoke, the magnetizing coil generating an alternating magnetic flux that is substantially equal to the magnetic flux density of the permanent magnet in the closed magnetic circuit and that is reverse to and forward of the magnetic flux direction. Therefore, even if a small amount of AC power is input, a magnetic flux in the magnetic flux direction opposite to the magnetic flux direction of the permanent magnet in the closed magnetic circuit is added to form an open magnetic circuit due to the magnetic pole repulsion action, and it is connected to the magnetizing unit and has a high permeability. Since an induction yoke having a magnetic susceptibility and made of a soft magnetic material is formed, and an output unit provided with an induction coil for extracting an induced electric power is provided on one side of the induction yoke, the magnetic flux and the magnetization by the permanent magnet are formed. Koi The magnetic flux generated by is electromagnetically induced in the induction yoke of the output unit, and an appropriate number of magnetizing units and output units are alternately closed and the whole is integrally connected like a ring. The electromagnetic induction between each magnetizing unit and the output unit acts to form a circulating magnetic path in the entire connection, and the interaction associated with the formation of the circulating magnetic path is weighted to provide strong electromagnetic induction. Becomes In addition, when a forward magnetic flux is added by the magnetizing coil, the magnetic flux density in the magnetizing unit is significantly increased and a closed magnetic circuit is formed, so that the magnetic flux in the induction yoke is strongly absorbed by the yoke of the magnetizing unit connected to it. Together with this, a strong electromagnetic induction action acts on the induction yoke, so that a large output power can be extracted from the induction coil with respect to the input power to the magnetizing coil. Further, by appropriately arranging a plurality of units of the present invention including a magnetizing unit and an output unit in series, extremely large output power can be obtained as compared with input power.

[0008]

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 is an explanatory view of the power generation method of the present invention, in which a magnetizing unit 1 is a permanent magnet 1A magnetized to a required magnetic flux density.
A yoke 1B made of a soft magnetic material having a high magnetic permeability is formed with the magnetic flux 10A of the permanent magnet 1A magnetized in one direction in the yoke 1B by the yoke 1B to maintain a closed magnetic path. It On one side of the yoke 1B, there is provided a magnetizing coil 1C that generates an alternating magnetic flux so as to be approximately equal to the magnetic flux density of the permanent magnet 1A that magnetizes in the closed magnetic circuit, and to be reverse and forward to the magnetic flux direction. ing.

In such a case, the permanent magnet 1A is naturally preferable to have a large magnetic flux density and a maximum energy product in order to use the maximum energy product as the induced power by electromagnetic induction. ,
Specifically, alnico magnets (residual magnetic flux density 8.2 to 1
1.5 KG, maximum energy product 11.0 MGOe),
Samarium cobalt magnet (residual magnetic flux density 8.2 to 1
1.2 KG, maximum energy product 16 to 32 MGOe)
Or neodymium iron boron magnet (residual magnetic flux density 10.5
To 13.0 KG, maximum energy product 30 to 55 MG
Oe) etc. are desired. Further, the yoke 1B is required to have a high saturation magnetic flux density and a high magnetic permeability, a low coercivity and a low hysteresis loss, and a low magnetization loss in an alternating magnetic field. Therefore, it is preferable to use a directional silicon steel strip or a permalloy. Use is desired.

The magnetizing coil 1C is made into an open magnetic circuit due to the repulsion of the magnetic flux due to the generation of a magnetic flux having a magnetic flux density substantially equal to the magnetic flux density that runs in one direction from the permanent magnet 1A to the inside of the yoke 1B, and is reverse to the magnetic flux direction. The electromagnetic induction is performed by the demagnetization by the magnetic field and the weighting of the magnetic flux due to the generation of the forward magnetic flux and the generation of the so-called alternating magnetic flux due to the closed magnetic circuit. The product [m ² ], [T] indicates 10 G), and (Representing the length of the magnetizing circuit) is used, specifically, the permanent magnet 1
It is determined in consideration of the magnetic flux density of A, the magnetic flux density of magnetism in the yoke 1B, the cross-sectional area of the yoke 1B, the leakage factor in the magnetic circuit, the winding resistance, the frequency of the AC power supply, and the like. In addition, since an alternating magnetic flux is generated in the magnetizing coil 1C, the AC power source 1D is naturally connected and input.

An output unit 2 is arranged so as to be connected to the magnetizing unit 1 thus formed. The output unit 2 is made to have a repulsion-open magnetic path by alternating with the magnetic flux direction of the permanent magnet 1A by the alternating magnetic flux generated by the magnetizing coil 1C of the magnetizing unit 1, and magnetic flux weighting is performed by the forward magnetic flux direction of the permanent magnet 1A. And an induction yoke 2A made of a soft magnetic material having a high magnetic permeability in order to perform electromagnetic induction associated with closed magnetization. The induction yoke 2A is preferably the permanent magnet 1A forming the magnetization unit 1 and the entire yoke 1B. It is preferable that the shape and the cross-sectional area are substantially the same. An induction coil 2B is formed on one side of the induction yoke 2A so as to extract the induced electric power due to the electromagnetic induction by the magnetizing unit 1. When forming the induction coil 2B, the induction yoke 2
If the magnetic flux density associated with the electromagnetic induction of A is known, the formula of the induced voltage, that is, e [V] = B1υ (where e [V] induced voltage, B
It may be formed in consideration of [T] or [wb / m ² ] magnetic flux density, 1 [m] effective conductor length, and ν [m / s] conductor moving speed).

In addition, what is essential in the present invention is that the magnetizing units 1 and the output units 2 thus formed are connected alternately in an appropriate number and the edges thereof are closed so that the whole is integrally formed in an annular or angular shape. To connect to. Of course, in the power generator of the present invention, an appropriate connecting tool (not shown) is used to connect and close the magnetizing units 1 and the output units 2 in an appropriate number and in an annular or angular shape. Of course, the connecting tool is made of a non-magnetic material that does not exert an electromagnetic induction effect. The magnetizing unit 1 and the output unit 2 are connected so as to be appropriately connected alternately and closed, so that the magnetizing unit 1 has a mutual effect on the electromagnetic induction caused by the demagnetization by the opening magnetic circuit and the absorption by the closing magnetic circuit. This is because the action works and a stronger electromagnetic induction action is realized, and the electromagnetic induction action will be described with reference to FIGS. 2 to 4.

FIG. 2 is an explanatory view of electromagnetic induction in an open magnetic circuit between the magnetizing unit 1 and the output unit 2, and a yoke formed by sandwiching a permanent magnet 1A magnetized to a required magnetic flux density in FIG. When the current from the AC power supply 1D flows in the direction shown in the drawing to the magnetizing coil 1C provided on one side of the magnet 1B, the magnetizing action of the magnetizing coil 1C causes ▲ N to appear on the yoke 1B.
The magnetic poles ▼ and ▲ S are generated, and the magnetic flux 11A generated in the magnetizing coil 1C acts in the direction shown in the figure, but repulsion occurs in the direction of the magnetic flux 10A from the permanent magnet 1A and in the yoke 1B. The closed magnetic circuit of only the magnetic flux 10A is made into an open magnetic circuit and is demagnetized by the induction yoke 2A of the output unit 2 which is connected, and the connection surface of the induction yoke 2A is magnetized to have opposite magnetic poles. Thus, the magnetizing unit 1 has an AC power supply 1D
Is connected and input, a current in the direction shown in FIG. 3 is instantaneously input. That is, when the direction of the current input to the magnetizing coil 1C is changed, the magnetizing action of the magnetizing coil 1C causes the magnetic poles of ▲ S ▼ and ▲ N ▼ to be generated in the yoke 1B, and the magnetic flux direction goes forward with the magnetic flux 10A of the permanent magnet 1A. For this reason, the magnetic flux density is changed to a closed magnetic circuit and magnetizes in the yoke 1B, so that the magnetic flux magnetized by the induction yoke 2A of the output unit 2 is absorbed by the yoke 1B of the magnetizing unit 1. Since the input AC power supply 1D normally changes its current direction in a cycle of 50 or 60 HZ, the yoke 1B of the magnetizing unit 1 is demagnetized by the open magnetic path and magnetized by the closed magnetic path in accordance with the change in the current direction. By repeating the electromagnetic induction, the induction yoke 2A of the connected output unit 2 is electromagnetically induced.

Further, according to the present invention, the magnetizing unit 1B and the output unit 2 are connected in an appropriate number and the edges are closed as shown in FIG. As described above, the electromagnetic induction works between them, but the magnetizing coils 1C, 1C, ... Of the respective magnetizing units 1 generate magnetic fluxes that are opposite to the magnetic flux directions of the permanent magnets 1A, 1A. , The induction yokes 2A, 2A ... Of the output units 2, 2 ...
Is magnetized, an appropriate number of magnetizing units 1 and output units 2 are alternately connected as shown in FIG. 5 and the circulating magnetic path 3 is formed over the whole with the edges closed. Therefore, at the time of demagnetization accompanying the opening of the magnetizing unit 1, an accelerating force due to the interaction associated with the formation of the orbiting magnetic path 3 acts, and particularly the magnetic flux of the permanent magnets 1A, 1A ... Generates from the magnetizing coil 1C. The magnetic flux is also effectively released and the magnetization of the induction yokes 2A, 2A ... Of the output units 2, 2 ... Is increased.

If the generated magnetic flux in the magnetizing coils 1C, 1C ... goes in the direction of the magnetic flux of the permanent magnets 1A, 1A ..., the magnetizing units 1, 1 ... Form a closed magnetic circuit with a large magnetic flux density. , The magnetic fluxes of the induction yokes 2A, 2A ... Of the output units 2, 2 ... With high magnetization are rapidly absorbed, and due to the alternation of demagnetization and absorption, the output unit 2.2 has a high electromagnetic induction. As a result, a large electric power can be obtained from the induction coils 2B, 2B, ...

Therefore, the present invention relates to a power generation method and a power generation device, and the range of use thereof is such that industrial or household power is required to have a high voltage and high current, and therefore various equipments and hard tools such as small power can be used. It is necessary to consider not only the use of electric power for industrial and household purposes but also the use of solar cells and dry cells as input. On the other hand, since the magnetic flux density and the maximum energy product of the permanent magnet 1A have their own limits, there is no particular problem in generating small power, but when generating large power, as shown in FIG. It is desired to deal with a configuration in which an appropriate number of units 2 are alternately connected to each other and the edges are closed as one unit, and an appropriate number of units are connected in series. As a matter of course, when a direct current such as a solar battery or a dry battery is used as an input power source, an alternating current conversion device (inverter) is interposed.

[0017]

As described above, according to the present invention, a permanent magnet magnetized to have a required magnetic flux density is sandwiched by a yoke made of a soft magnetic material having a high magnetic permeability, and the magnetic flux of the permanent magnet runs in one direction. And a closed magnetic circuit is maintained, and a magnetizing coil is provided on one side of the yoke that is capable of generating an alternating magnetic flux that is approximately equal to the magnetic flux of a permanent magnet that runs inside the yoke and that is reverse and forward in the direction of the magnetic flux. A magnetizing unit and an induction yoke made of a soft magnetic material having a high magnetic permeability, which is arranged so as to be connected to the magnetizing unit,
And an output unit provided with an induction coil for extracting the induced electric power associated with electromagnetic induction on one side of the induction yoke, and the configuration is such that an appropriate number of them are alternately connected and the edges thereof are closed. By inputting a small amount of AC power to the magnetizing coil of the magnetizing unit, an alternating magnetic flux is generated that is reverse and forward with respect to the strong magnetic flux of the permanent magnet that runs in the yoke.
The running magnetic path of the magnetizing unit is opened and closed, and when the magnetic path is opened, not only the magnetic flux of the permanent magnet but also the magnetic flux generated by the magnetizing coil is released and magnetized to the connected output unit, and Since the magnetic flux in the magnetizing unit increases significantly when the magnetic circuit is closed, the magnetized magnetic flux in the output unit is rapidly absorbed, and these are alternating according to the frequency of the AC power. As a result, the magnetizing unit and the output unit are alternately connected to each other in an appropriate number and the edges thereof are closed, so that the magnetizing unit is magnetized to the output unit by opening the magnetic path. The formation of a magnetic path that circulates the entire structure occurs, and the interaction due to the formation of the circular magnetic path further promotes the demagnetization from the magnetizing unit to the output unit, thereby exerting strong electromagnetic induction. Therefore, by making a specific magnetic path design based on the AC power source to be used, its frequency, and the desired output power, it is possible to obtain output power that is several times to several tens of times higher than the input power, and the present invention is for generating power. Since the device is small and easy to make, it can be realized at extremely low cost, and there is no danger of disturbing the environment such as generation of vibration and noise and generation of exhaust gas waste during power generation. It is a power generation method and a power generation device that greatly contribute to realization.
