Description

  The present invention relates to a power generation system and a generator, for example, and more particularly to a power generation system and a generator using hydraulic power and gravity.

  Conventionally, thermal power and nuclear power have been the main power generation mechanisms. However, in thermal power generation, carbon dioxide emissions and the use of finite fossil fuels (depending on the country, there are many places where the fuel must be relied upon for imports. ) Radiation problems (such as the management of radioactive waste) have been regarded as a problem in nuclear power. In addition, there is a mechanism of power generation such as sunlight and geothermal heat, but in addition to being influenced by the weather, the price of electricity obtained by such power generation has been regarded as a problem.

  On the other hand, in the field of patents, measures as shown in Patent Documents 1, 2, and 3 have been taken.

  In Patent Document 1, a spiral rail (track for rolling an iron ball or the like) with an arbitrary inclination angle is attached to the inside of a cylindrical outer wall. A device for returning an iron ball or the like using an explosive (air pressure, hydraulic pressure, a device for launching a ball like a pachinko machine, etc.) is disclosed. In this configuration, the power generated by the generator is transformed by a transformer and moved to an upper position like an elevator or escalator using an electric motor, etc., and the rotating shaft is indirectly connected to the generator. In such a case, a gear or the like is attached to the rotation shaft, and another rotation shaft is provided on the gear, and the gear is used to move it to the upper position.

  Because of this configuration, there is a very high risk associated with using explosives. Regarding the environment, there is a risk that the noise may affect the surrounding environment. In particular, when using explosives, it is extremely important to understand the structure of the chemical substance that is the main component, so that high level of expertise is required, and it is difficult to implement easily.

  In Patent Document 2, a conductive coil is provided on both walls of a two-wall donut-shaped guideway, and a rotating propulsion rotates between the two walls. The propulsion is equipped with a conductive magnet, and a structure in which a shaft is directly connected to a shaft by a shut is disclosed. In the primary side power generation A section, the above-described attractive energy is driven, and a large gear, two transmission gears are used to generate power in the inverter generator, and the primary side power generation is performed in the B secondary side power generation B section linear high speed rotating shaft. It is supplied to the device and generates high output power. The propellant rotates at high speed by passing the current supplied from the A section through the conductive coil of the guideway. Originally, it is a linear power generation in which a linear method of linear motion is circularly moved to a guide way to cause circular motion, and the propellant and shaft rotate at high speed.

In such a configuration, the use of electric magnets may cause the possibility of attracting to other places, and the workability of assembly and the like may be affected by the attractive force. It can happen. The amount of power generation is also expected to decrease due to fluctuations in the attractive force of the magnet. In any case, precision control is difficult with respect to magnetism.
JP 2002-370091 A Japanese Patent No. 4022251

The present invention has been made in order to solve the above-described problems in the prior art, and is efficient in terms of environment, resources, and environment using eco-energy that does not affect the environment in power generation. An object of the present invention is to provide a power generation system and a power generation apparatus.

  A more detailed object of the present invention is to use an eco-friendly clean eco-energy such as gravity and hydro energy, and to efficiently supply power, so that there is no need to use limited fossil energy. The object is to provide a safe power generation method and power generation apparatus that can also improve the problem of global warming.

  A further object of the present invention is to provide a gravitational power generation apparatus that can reform and power generation more economically and practically by reforming an existing hydroelectric power generation system. Another object of the present invention is to provide a power generation method and a power generator in which power devices with high power generation efficiency are added.

  In order to solve such problems, a power generation system according to the present invention includes an inclined rail structure, a rotating mechanism that rotates as it descends on the rail structure, and converts the rotational force generated in the rotating mechanism into electric power. A power generation structure including at least a power conversion mechanism for storing the power obtained by converting the power thus obtained, and a lifting structure that is disposed in the vicinity of the rail structure and converts the water flow into lift gravity using the water flow. And the generator is lifted from the lowered position to an arbitrary position including a starting position on the rail structure by the lifting structure.

  The inclined rail structure has a function of providing a track on which the power generation structure (body) descends and rotates. For example, when the power generation structure has wheels, it may be a rail structure corresponding to this. Such a rail structure is preferably provided with a fall prevention mechanism (for example, a rising structure or the like) for preventing fall due to shaking or the like. The rail structure is formed to have an inclination, but this inclination angle is not particularly limited as long as the power generation structure (body) has a sufficient angle to start and continue the descent / rotation motion. The overall trajectory of the rail structure is not limited and may be any of a spiral shape, a straight line, a curved shape, and the like. The upper and lower rail widths of the rail structure are the same. It is good to set it as the arrangement | positioning with which the apparatus for sending the generator which lowered | hung this rail upper part and a rail into the rail upper part was provided side by side.

  The power generation structure is a mechanism in which a generator provided with a rotating body rotates and descends on an inclined rail with gravity energy and converts the rotational energy into electric power.

The rotation mechanism is a structure that can rotate downward on the rail structure, and is realized by, for example, a combination including a wheel, an axle, and a gear coaxially connected thereto. It rotates on the rail in a circle such as a wheel and is connected directly or indirectly to the generator.

The power conversion mechanism has a function of converting rotational force generated in the rotation mechanism into electric power. More specifically, it is a machine (electric power device) that obtains electric energy (electric power) from mechanical energy (work) using the law of electromagnetic induction. For example, two coils are attached to the upper part, and below that By rotating a placed U-shaped permanent magnet to generate electricity (Hypolite-Pixie method) or by rotating a copper disk sandwiched between the magnetic poles of a U-shaped permanent magnet, This can be realized by means of generating a potential difference between the circle and the center (Faraday method). For example, a rotating body related to the rotating mechanism and a motor may be directly connected by a shaft, and the motor may be driven by the rotation of the rotating unit to generate power. In this case, the rotating body may be configured to be connected to the generator by combining the rotating bodies having different inner diameters (large inner diameter and small inner diameter).

The power storage unit has a function of storing electric charge, and is realized by, for example, a capacitor or a battery. It is good also as a structure provided with two types of electrical storage parts, the transmission line which transmits the stored electric power, and the electric power charging machine which charges and stores the stored electric power.

Lifting structure is a device that has the function to lift the generator that has finished descending on the rail to the starting position (upper point) on the rail structure against gravity. Clean energy is used for the power of lifting. Use. Therefore, it is preferable that the lifting structure is arranged in the vicinity of the rail structure in order to minimize the movement at the horizontal distance. The use of clean energy refers to hydropower, wind power, sunlight or other energy. With this lifting structure, the generator is lifted from the lowered position to any position including the starting position on the rail structure.

With the configuration as described above, in the power generation device according to the present invention, by rotating on the rail having an inclination, the generator is rotated by the gravitational energy generated when the inclination is lowered, and electric power is generated, and the generated electric power is stored. Thus, electrical energy can be generated and stored by clean means. Furthermore, the generator that has descended on the rail is moved from the low position to the upper position by the lifting structure. That is, the rotating unit related to the lifting structure is linked to the conveying unit, rotated by hydraulic power, wind power, or other energy, puts a generator on the rotated rotating unit, and is connected to the upper part of the rail. To send. This allows repeated descent operations. Therefore, the driving energy of the generator becomes unnecessary and can be used semipermanently. Furthermore, in the case where the inner diameters of the rotating bodies are made different, the inclined rotation speed increases and the amount of power generation also increases, so that the efficiency of power generation is improved. In addition, in the case of a configuration in which two types of power storage methods are employed in the power storage unit, it is possible to achieve load distribution during power storage.

  In the above configuration, the rail structure may form a substantially spiral structure, and the rotating mechanism may be configured to descend in a loop shape on the rail structure.

  According to such a configuration, since the spiral shape is formed, the power generation device construction area can be saved. Therefore, the problem of securing the construction site of the power generation device can be reduced.

In the power generation system according to the present application, in addition to the above-described configuration, the lifting structure may be disposed in the vicinity of the water flow, and may be configured to use the energy generated by the water turbine using the water flow.

The structure of the water wheel may be an impulse water wheel that changes the pressure head to a speed head and acts on the water wheel, or a reaction water wheel that causes the pressure head to act on the water wheel. The impulsive turbine is a Pelton turbine that rotates the jet stream from the nozzle against the bucket around the runner, and the stream adjusted by the guide vane flows from the top to the center of the horizontal cylindrical runner, and from the center at the bottom. A cross-flow turbine having a structure that flows down to the outside or a targo impulse turbine that is rotated from one side of a runner may be used. The reaction water turbine is a Francis turbine in which the flowing water from the casing through the guide vanes flows in the radial direction into the outer periphery of the spiral runner and flows out in the axial direction. A mixed-flow turbine that flows into the outer periphery of the shaft in an oblique direction and flows out in the axial direction, and a propeller turbine in which the flow of water flowing in from the axial direction flows out in the axial direction And a tubular turbine in which a generator or the like is housed in an underwater cylindrical casing and a guide vane or runner is installed in the rear part thereof.

  According to such a configuration, the lifting structure includes a rotating part and a conveying part, and the generator that has fallen and rotated from the upper position of the rail is sent back to the upper place of the rail by hydraulic power or the like, so that the driving energy of the conveying part is saved. It is intended. Since the lift is generated by using a water flow such as a water turbine, driving energy for lifting is unnecessary.

In the power generation method according to the present application, in addition to the above-described configuration, the power generation structure has a predetermined inner diameter and a first wheel abutted on the rail structure and an inner diameter smaller than the first wheel. A second wheel that is in contact with the first wheel, and is brought into contact with the rail structure by lowering and rotating the power generation structure from an arbitrary position including a starting position on the rail structure. It can also be set as the structure which increases rotation of the said 2nd wheel rather than rotation of a 1st wheel.

  According to such a configuration, the generator according to the power generation means of the power generator according to the present invention is connected to a wheel and a wheel having an inner diameter smaller than that, and when the generator is dropped and rotated from a position on the rail, the inner diameter is reduced. Since the falling rotational momentum of the small wheel is increased over the other wheel, an increase in rotational speed is achieved. Therefore, the efficiency of power supply can be improved by reducing the inner diameter of the wheel.

  Moreover, in order to solve the said subject, this application which concerns on a generator WHEREIN: When the wheel which has a fitting part fitted so that it may fit on a rail structure, the axle shaft connected to the said wheel, and the said wheel rotate Power conversion means for converting the rotational force generated in the power into electric power, and a power storage unit for storing electric power obtained by the power conversion means.

  A fitting part says sufficient structure to prevent that a wheel deviates from a rail structure, and falls off, and there is no limitation in the shape and material. For example, it can also be realized by forming a rising on the cross section of the wheel.

  By being configured as described above, since the wheels related to the generator are held so as not to deviate from the rail structure, the rail structure can be lowered and rotated safely and reliably, and stable power generation and power supply can be achieved. Is made.

In the present application, in terms of resources, the use of gravity and (for example) hydropower anywhere on the earth is highly permanent. Therefore, it is possible to save resources used in other methods such as power generation. In terms of the environment, thermal power emits materials that are said to cause global warming and acid rain, such as nitrogen and sulfur compounds and oxygen dioxide, and nuclear power emits radioactive waste, etc. since the substance of clean power generation hardly issued, and is suitable for CO ₂ reduction of "global warming". In addition, since it is a natural energy, it is difficult to consider the impact on the environment, and there is an advantage that stable power generation can be expected. In terms of economics, both gravity and hydropower can be used free of charge, so maintenance costs are low, and unlike other power generation methods, installation costs are low.

  The best mode for carrying out the present invention will be described below with reference to the drawings.
