Description

The present invention relates to a power generation device that uses renewable energy, and more particularly to a simple and highly efficient fluid power generation device that uses a fluid such as wind power and sunlight.

Natural energy that can be used as so-called renewable energy includes wind power, water power, sunlight, solar heat, geothermal heat, biomass, and the like. Such natural energy can be regenerated in a relatively short time even if used once, and is used as clean energy to replace fossil fuel such as petroleum. In particular, power generation using wind power and so-called solar power generation using sunlight are rapidly spreading.

BACKGROUND ART Power generation using wind power is generally known as a wind turbine generator that receives wind from a rotating wind turbine and generates electric power by rotating a generator with the rotational force obtained from the wind. Further, in power generation using sunlight, a photoelectric conversion device called a so-called solar panel is used.

In the field of wind power generation, a power generator called a pendulum type is also known in addition to the one using the above-described wind turbine. For example, in a power generation device using the oscillating motion of a plate-like oscillating plate (blade) disclosed in Patent Document 1, the oscillating plate is fixed to a shaft installed in the lateral direction, and the oscillating plate generates wind. The reciprocating rotation of the shaft caused by receiving and reciprocatingly oscillating is transmitted to the shaft of the generator through the one-way clutch. In addition, Patent Document 1 also describes that the rotation unevenness is reduced by a flywheel.

In addition, Patent Document 2 by the inventors of the present application can be cited as an example in which wind energy using a rocking plate and solar energy are used in combination. Patent Document 2 discloses a structure in which the oscillating motion of an oscillating plate is converted into the reciprocating motion of an armature that constitutes a linear electromagnetic induction power generator (linear generator) to generate electric power. Also disclosed is a fluid power generation device in which a solar panel is attached to the surface of the oscillating plate and solar energy is also used for power generation.

JP, 2017-28885, A Patent No. 5969154

The pendulum-type power generation device disclosed in Patent Document 1 is provided with a pair of flywheels having different rotation reversal directions attached to a shaft that suspends the rocking plate to suppress uneven rotation of the shaft due to reciprocating motion of the rocking plate. The rotation conversion device for that purpose uses a complicated magnetic rotation structure. Further, the generator shaft is provided separately from the shaft of the oscillating plate, and two one-way clutches are provided, so that the structure is complicated.

In the hybrid power generation device disclosed in Patent Document 2, the transmission torque of the oscillating shaft in the pendulum motion due to intermittently generated wind power of intermittent wind power cannot be sufficiently recovered by the linear electromagnetic induction power generation device. In addition, the power generation capacity of solar panels decreases at night and depending on the weather. As it is, it is difficult to obtain stable power because it is greatly affected by wind conditions (wind force, wind direction), nighttime and weather conditions.

Unlike large-scale wind power generators and mega-solar power generation facilities, pendulum type power generators are effective as a simple and safe power generation means for small businesses and households. However, as described above, many problems to be solved at present are hindering the spread.

The present invention is to solve the above-mentioned problems of the prior art. In addition to increasing the amount of electric power generated during the day by using a solar panel in a pendulum system, the shape of the oscillating plate is improved to improve wind from any direction. However, the swing motion can be performed efficiently. As a result, the wind power can be used efficiently while the installation position of the power generator (power generation site) is fixed at a position where the wind direction is statistically large, and the reflected light of the snow cover can also be used positively in the snowfall area, which results in solar power generation. The efficiency of can be improved. Further, by accumulating energy in the flywheel and the battery, the rotational speed of the flywheel can be increased with the assistance of the battery when the wind power or the solar energy decreases.

A typical configuration of the present invention for achieving the above object will be described below. In addition, in this item, in order to facilitate understanding of the present invention, reference numerals in the embodiments corresponding to the respective constituents are added.

The present invention cooperates with a oscillating plate (oscillating blade) 1 for generating electric power by rotating a generator rotating shaft 11 with rotational energy obtained from wind power, and a solar panel 10 for converting sunlight into electric energy. It is a fluid power generation device that generates electric power by using the following features.

(1) A machine frame 4, a rocking shaft (also referred to as a rocking rotary shaft) 2 mounted in the lateral direction of the machine frame, a front wind receiving surface 1f and a rear wind receiving surface 1g, and the rocking shaft. 2, an upper edge of which is fixed and suspended to reciprocally swing around the swing rotation axis, a generator 6 which is rotated by the swing rotation axis 2, and the swing rotation axis. A rotary converter 3 installed between the generator 2 and the generator 6 to convert the reciprocating rotation of the swinging rotary shaft 2 into a unidirectional rotation for connection to the generator rotary shaft 11; A flywheel 5 fixed to a shaft 11 to rotate; a front solar panel 10a and/or a rear solar panel 10b attached to one or both of a front wind receiving surface 1f and a rear wind receiving surface 1g of the swing blade 1. Have.

(2) The oscillating plate 1 in (1) above has an arc shape whose cross section is convex toward the front wind receiving surface side.

(3) The oscillating plate 1 in (2) above has a blade shape in which the thickness of the lateral cross section from the side edge in the vertical direction to the central portion is gradually smaller.

(4) Both side edges of the cross section of the oscillating plate 1 of the above (1) are bow chordal (concave) toward the front wind receiving surface side, and the rear wind receiving surface side is flat.

(5) The oscillating plate 1 of (4) has a blade shape in which the thickness of the lateral cross section from the side edge in the vertical direction to the central portion is gradually smaller.

(6) On the front surface and the rear surface of the oscillating plate 1 of (1) to (5), a large number of minute convex portions (protruding portions) 12a that give a turbulent flow to the passing air flow are randomly formed. This minute convex portion can be formed by spotting a transparent resin or the like on the surface of the solar substrate and curing it. This avoids turbulence, vortex, and the like that occur in the airflow that passes through the surface of the oscillating plate at high speed, and suppresses the seismic intensity of the oscillating plate.

(7) On the front surface and the rear surface of the oscillating plate 1 of (1) to (5), a large number of minute recesses 12b that give a turbulent flow to the passing air flow are randomly formed. The minute recesses 12b can be obtained by forming dimples on the surface substrate of the solar panel in advance.

(8) The generator is a motor generator (MG) that operates as an electric motor, and includes a battery 23 that stores generated electric power, and the electric power of the battery allows the motor generator to rotate the flywheel.

It is needless to say that the present invention is not limited to the above-mentioned configuration and the configurations described in the examples described later, and various modifications can be made within the scope of the technical idea of the present invention.

In the fluid power generation device according to the present invention, the pendulum type power generation device is used together with the solar panel, and the shape of the rocking plate is improved so that the rocking motion can be efficiently performed by wind from any direction. Further, even if the installation position of the oscillating plate is fixed at a position where the annual wind direction is statistically large, the wind force can be efficiently used even if the wind direction changes. Furthermore, in a snowfall area, the solar panel on the back can utilize the reflected light from the snow cover to improve power generation efficiency.

By making the shape of the rocking plate similar to the shape of a wing of an aircraft, the lift effect of the rocking plate is improved. In addition, by forming a minute concave portion or convex portion on the surface, it is possible to reduce the lift reduction due to the turbulent air flow and efficiently swing.

When the rotation speed of the flywheel that rotates with the rotation of the generator is not sufficient (starting, no wind, etc.), the flywheel is equipped with a sensor that detects the rotation status, and the generator is activated when rotation below the set value is detected. In the electric motor mode, the flywheel is rotated up to a predetermined rotation speed with the electric power from the battery. As a result, not only the battery but also the flywheel can secure energy storage, and uneven power generation by the rocking plate that intermittently rocks can be reduced.

Hereinafter, embodiments of a fluid power generation device according to the present invention will be described in detail with reference to the drawings of the embodiments.

FIG. 1 is an explanatory diagram of the overall configuration of a first embodiment of a fluid power generation device according to the present invention. 2 is an explanatory view of the action of the oscillating plate in FIG. 1, FIG. 3 is a cross-sectional view taken along the line BB of FIG. 2, and FIG. 4 is a top view of the oscillating plate viewed from the arrow C in FIG. .. The generator will be described as being installed in the machine frame 4 installed on the ground or the like (generator installation place) by the foundation 14 and installed with the south side facing forward. The machine frame 4 is constructed of a strong material, which is preferably an iron pipe, so as to withstand strong winds. An oscillating plate (also referred to as a wind receiving plate or a blade) 1 is fixed to an oscillating shaft 2 mounted laterally (horizontally) in a central region of the machine frame 4.

The oscillating plate 1 has a front wind receiving surface 1f and a rear wind receiving surface 1g, and is suspended by fixing an upper cover 1a provided on an upper edge of the oscillating shaft 2 around the oscillating shaft 2. Is installed between the swing shaft 2 and the generator 6, and the generator 6 is rotated by the rotational force transmitted from the swing shaft 2. The rotation converter 3 is configured to convert reciprocating rotation (reciprocating rocking) of the rocking shaft 2 into one-direction rotation and connect the same to the generator rotating shaft 11.

In converting the reciprocating motion of the oscillating plate 1 into the shaft rotating motion, it is necessary to accelerate the shaft connected to the generator in order to obtain a stable power generation amount. Therefore, the rotation converter 3 that converts the reciprocating motion into the unidirectional rotating motion can be provided with a speed increasing gear. Further, a flywheel 5 that is fixed to the generator rotating shaft 11 and rotates is provided. The flywheel 5 can store momentary high energy when the wind is strong, and the stored energy can accelerate the rotation as needed, and thus has an effect of averaging wind energy. The capacity of the flywheel 5 is determined in consideration of wind power data of the installation site, required torque of the generator, and the like.
The front solar panel 10a and the rear solar panel 10b are attached to both or one of the front wind receiving surface 1f and the rear wind receiving surface 1g of the rocking plate 1. XX is a horizontal direction (horizontal direction), Y-Y is a vertical direction (longitudinal direction), and ZZ shown in FIGS. 5 and 6 is a front-back direction.

The transverse section (horizontal section) of the oscillating plate 1 has an arc shape that is convex toward the surface wind receiving surface side (see FIGS. 1 to 3 ). As shown in FIG. 2, it can be considered that winds roughly come from four directions to the rocking plate 1. These winds are the front wind coming from the direction of the range W1 in front of the rocking plate 1, the rear wind coming from the direction of the range W2 behind the rocking plate 1, and the wind of the rocking plate 1. It can be shown in four directions: the right wind coming from the direction indicated by W3 on the right side and the left wind coming from the direction shown by W4 on the left side of the oscillating plate 1.

The wind that blows naturally on the ground is not always determined from one direction, but it constantly changes depending on the season, atmospheric pressure arrangement, topography, surrounding environment such as buildings and forests. In many wind turbine power generation systems that use rotor blades, the wind direction sensor detects the wind direction and controls the direction of the rotor blade to the wind direction. However, adding a wind direction response mechanism to a small-scale power generation device complicates the configuration and increases the cost. In particular, a simple power generator using an oscillating plate is required to have a structure as simple as possible.

As shown in FIG. 2, the oscillating plate 1 according to the present embodiment is adapted to cope with wind from any direction of 360 degrees around, so that the oscillating plate can be opposed to the wind direction. Without this, it is possible to preferably perform power generation. However, the directions in which the oscillating plate 1 efficiently receives the wind force are the front wind W1 and the rear wind W2 in FIG. FIG. 2 shows the main regions of the front wind receiving surface 1f and the rear wind receiving surface 1g of the rocking plate 1. The solar panel is not shown in FIG.

Further, with respect to the rightward wind W3 and the leftward wind W4 shown in FIG. 2, the transverse cross section of the oscillating plate 1 has an arc shape (bow chord shape (arc shape)) and an aircraft wing. By utilizing the lift force based on the same principle, it is possible to obtain a rocking motion that is much more efficient with respect to the wind from the lateral direction than a mere flat rocking plate. The winds on the front region side of the right wind W3 and the left wind W4 mainly act on the front wind receiving face 1f, and the winds on the rear region side of the right wind W3 and the left wind W4 mainly act on the rear wind receiving face 1g. To do.

FIG. 3 shows a cross section taken along line BB of the rocking plate 1 shown in FIG. Further, FIG. 4 is a top view seen from the direction of →C in FIG. The oscillating plate 1 has an arc-shaped cross section, and an upper cover 1a is attached to cover the upper part of the oscillating plate 1b. The upper cover 1a has a function of preventing the wind coming from the rear from escaping upward and reducing the wind pressure applied to the oscillating plate 1. The swing shaft 2 is fixed to the upper cover, and the swing plate 1 swings back and forth while being suspended from the swing shaft 2.

A front solar panel 10a and a rear solar panel 10b are attached to the front and rear surfaces of the oscillating plate 1, respectively. In this embodiment, these solar panels are attached so as to cover the entire front surface and the rear surface of the oscillating plate 1, but the present invention is not limited to this, and each surface may be partially covered. Good.

The oscillating plate 1 oscillates in response to wind force, converts the reciprocal oscillating oscillation of the oscillating shaft 2 into unidirectional rotation of the generator shaft, and rotates the generator rotating shaft 11 (see FIG. 8 described later) to generate power I do. The non-uniform rotation of the generator rotating shaft 11 due to the non-uniform wind force is supplemented by the rotational energy accumulated in the flywheel 5 and smoothed.

Further, the solar panels 10a and 10b attached to the rocking plate 1 receive sunlight in the daytime to generate electricity. The solar panel 10b attached to the rear wind receiving surface receives the reflected light from the surroundings to generate electricity. In a snowy country or the like, the reflected light from the snow is strong, so that the solar panel 10b functions more effectively. The same applies to desert areas, water surfaces, and their vicinity.

According to the first embodiment described above, the oscillating plate (oscillating blade) 1 for rotating the generator rotating shaft 11 with the rotational energy obtained from the wind power to generate electric power, and the solar panel 10 for converting sunlight into electric energy. It is possible to provide a fluid power generation device that generates electric power in cooperation with.

FIG. 5 is an explanatory view of an oscillating plate used in the second embodiment of the fluid power generation system according to the present invention. In this embodiment, the cross-sectional shape of the side edge 1c of the oscillating plate used in the first embodiment in the lateral direction XX is approximated to the airfoil shape of an aircraft. That is, the thickness d1 of both side edges 1c of the oscillating plate 1 is made large, and the plate thickness d2 of the central portion 1d in the vertical direction YY is gradually thinned to be the thinnest. In addition, ZZ shows the front-back direction. Other configurations are similar to those of the first embodiment.

According to the present embodiment, by adopting such an oscillating plate shape, the lift amount in the forward direction of the oscillating plate 1 by the wind W3 from the right direction or the wind W4 from the left direction is increased and the oscillating amount ( The swing angle) can be increased, and the amount of rotation of the motor shaft can be increased to increase the amount of power generation.

FIG. 6 is an explanatory view of an oscillating plate used in a third embodiment of the fluid power generation system according to the present invention. In this embodiment, the rocking plate used in the first embodiment is replaced with a single plate body, and the side edge cross-sectional shape in the lateral direction XX has a large thickness d3 only on the front side, and the other wings of the aircraft. It is an approximation of the type. That is, the thickness 1c of both side edges 1c of the oscillating plate 1 is increased, and the central portion 1d of the central portion in the vertical direction YY is gradually reduced to the minimum plate thickness d4. Other configurations are similar to those of the first embodiment.

Also in this embodiment, the amount of rocking (rocking angle) can be increased by increasing the lift of the rocking plate 1 in the forward direction by the wind W3 from the right direction or the wind W4 from the left direction, and thus the motor shaft. The amount of power generation can be increased by increasing the rotation amount of the.

FIG. 7 is an explanatory view of an oscillating plate used in the fourth embodiment of the fluid power generation system according to the present invention. The oscillating plate 1 according to the present embodiment has a large number of minute convex portions 12a that randomly generate turbulence in the air flow passing through the front surface and the back surface thereof. This minute convex portion can be formed by spotting a transparent resin or the like on the surface of the solar substrate and curing it. As a result, it is possible to avoid the turbulent flow and the vortex generated in the air flow that passes through the surface of the oscillating plate at high speed, and suppress the vibration of the oscillating plate.

Note that a large number of minute concave portions 12b can be formed at random instead of the minute convex portions 12a described above. The minute recesses 12b can be obtained by forming dimples on the surface substrate of the solar panel in advance.

According to the present embodiment, in addition to the effects of each of the above-described embodiments, turbulent flow and vortex generated in the air flow that passes through the surface of the oscillating plate at high speed are avoided, and vibration of the oscillating plate is suppressed. be able to.

FIG. 8 is an explanatory diagram of a configuration example of the rotation converter 3 in FIG. The same can be applied to the fluid power generation device of FIG. The rotation converter 3 is installed between the oscillating plate 1 and the generator 6, and converts the reciprocal rotation of the oscillating plate 1 due to the reciprocating motion of the oscillating plate 1 into one-direction rotation of the generator rotating shaft 11. It is an example of a mechanism for. In FIG. 8, the first gear 31 is fixed to the swing shaft 2, and the fifth gear 35 is fixed to the generator rotating shaft 11.

The third gear 33 and the fourth gear 34 are fixed to the driven gear shaft 37 and are rotatable in the same direction. However, the third gear 33 is a one-way rotating gear and transmits only the rotation in the direction of the outline thick arrow to the driven gear shaft 37. The second gear 32, which is an intermediate gear rotatably loaded on the intermediate shaft 36, is also a one-way rotating gear, so that only the rotation in the direction of the white thick arrow is transmitted to the driven gear shaft 37 via the third gear 33. Tell. Reference numeral 30 denotes a clutch that connects and disconnects the swing shaft 2 and the generator rotating shaft 11.

When the rocking shaft 2 rotates in the direction of the thick black arrow due to the rocking of the rocking plate 1, the clutch 30 is turned on (contact), and the generator rotating shaft 11 is rotated from the clutch 30 that is turned on in the direction of the thick black arrow. Then, the generator is rotated to generate electricity. At this time, the second gear 32 and the third gear 33 that mesh with the first gear 31 rotate freely, and the rotation of the first gear 31 is not transmitted to the fifth gear 35.

On the other hand, when the oscillating plate 1 oscillates to rotate the oscillating shaft 2 in the direction of the thick white arrow, the clutch 30 is turned off (disengaged), and the rotation is the second gear 32→the third gear 33→the fourth gear. It is transmitted from 34 to the fifth gear 35. As a result, the generator rotating shaft 11 is rotated in the same white thick arrow direction as the black thick arrow direction, and the generator 6 continues to generate power.

A flywheel is fixed to the generator rotating shaft 11, but is not shown in FIG.
The rotation conversion mechanism shown in FIG. 8 is merely an example, and many gear mechanisms other than this may be considered for achieving the same operation.

FIG. 9 is an explanatory diagram of the overall configuration of the fifth embodiment of the fluid power generation device according to the present invention. In this embodiment, the structure around the generator described in the first embodiment is arranged on both left and right sides of the oscillating plate 1. FIG. 9 corresponds to (a) of FIG.
The fluid power generation device of this embodiment is the same as the first embodiment of the present invention described with reference to FIG. The other configuration is similar to that of the first embodiment, and thus the description thereof is omitted.

According to the present embodiment, a relatively large-scale fluid power generation device can be configured by increasing the air receiving area of the oscillating plate 1. The power source is not limited to that shown in FIG. 9, and it is also possible to connect a larger number of rocking plates, a larger number of generators, and solar panels to form a larger power source.

FIG. 10 is a block diagram illustrating a control system of the fluid power generation device according to the present invention. The generator used in the fluid power generator according to the present invention is preferably a motor generator (MG) having an electric motor mode (motor mode).
In FIG. 10, the two generators 6a and 6b shown in FIG. 9 are used as the generator 6, but in the case of FIG. 1, only one motor generator 6a and one solar panel 10a are used. Should be understood as using.

A control device 22 that integrally controls these components is provided.

The control device 22 controls the normal operation of the generator 6 and the solar panel 10, and a rotation speed sensor 27 that monitors the rotation speed of the flywheel 5 and a swing that detects the swing direction (back and forth movement) of the swing plate 1. A swing plate swing direction detection sensor 28 for detecting the swing plate direction of the plate is provided. In addition to this, various sensors and control programs for monitoring the generated power of the generator 6 and the generated power of the solar panel to obtain the optimum power generation state are provided. When surplus power is generated, it can be connected to the power grid and sold.

The rotation speed sensor 27 can issue a command to the control device 22 to increase the rotation speed by using the electric power constantly charged in the battery 29 when the rotation speed of the flywheel becomes equal to or less than a specified value. The battery 29 supplies power to the load 25 as a backup power source when the power generated by the generator or the solar panel is reduced.

The direction detection sensor 28 detects the swing direction of the swing plate 1 and turns on/off the clutch 30 shown in FIG. As a result, unidirectional torque is supplied to the shaft of the generator regardless of the swing direction of the swing plate 1.
