Description

  The present invention relates to a combined power generation device combining solar power generation and wind power generation, which is used for various power sources by generating power using both solar power generation and wind power generation, and particularly enables continuous power generation for 24 hours day and night. The present invention relates to a combined power generation device that combines solar power generation and wind power generation to obtain clean energy by charging a storage battery.

In recent years, there has been an active movement to reduce the amount of gas polluting the atmosphere as a measure against global warming. One of the gases that pollute the atmosphere is carbon dioxide (CO ₂ ) generated by cultivating forests and burning fossil fuels, but clean energy instead of energy based on combustion of such fossil fuels, In particular, the spread of the use of electric power energy created from solar power generation and wind power generation using natural energy is being studied.

  Conventionally, solar power generation and wind power generation have been developed as separate systems. However, solar power generation is limited to the daytime when the weather is good, while wind power generation requires a certain level of wind power. Therefore, in order to obtain stable power continuously for 24 hours, it is difficult to carry out with only one of photovoltaic power generation or wind power generation. Therefore, the inventor of the present invention has proposed a power generation apparatus that generates power using both solar power generation and wind power generation (see Patent Document 1).

  This solar power generation system combined with wind power generation includes a solar panel that receives sunlight, a panel base that supports the solar panel, a support that supports the panel support in a non-rotatable state on the base, and the periphery of the support A wind turbine having a plurality of blades fixed to a bearing rotatably attached to the wind turbine and receiving wind around the wind turbine, and a generator for generating electric power by converting rotational energy received by the wind turbine into electric energy, It has an angle and shape to deflect the received wind and send it to the solar panel. As a result, natural energy can be used efficiently and power generation can be performed day and night and throughout the seasons.

  However, in the above power generation device, the wind hitting the windmill easily escapes outside the windmill, and it is difficult to efficiently use the received wind for rotation. Therefore, we examined increasing the size of the wind turbine in order to improve this point, but it was found that increasing the size of the wind turbine increases the resistance in the direction of rotation of the wind turbine, and cannot increase the power generation efficiency. Therefore, it has been necessary to develop a device that efficiently collects winds blowing from any direction direction of 360 degrees and efficiently and efficiently blows them to the optimum position of the windmill.

  In addition, the cup-type paddle used for wind power generation has a structure with high wind receiving efficiency in which the paddle is fixed to the tip of the rotary arm radially from the inner ring of the rotating shaft, but the rotation starting force against wind receiving is large. The wind pressure resistance in the direction of rotation applied to the entire windmill hinders the rotation efficiency of the windmill. Therefore, there has been a problem that the rotational starting force of the windmill cannot be obtained sufficiently and the conversion efficiency of the rotational torque is poor.

  Furthermore, the solar panel is installed with the installation direction inclined to the east or south where the sun rises, etc., and tilted around 35 ° with respect to the ground, so that sunlight can be received efficiently for a long time. Even in this way, there is a problem that the time period during which power generation is possible is limited to the time after noon from the morning when the early morning sun shines directly.

  Also, when installing solar panels, rather than making the solar panel one large size, installing it like a triangular pyramid roof to divide the solar panel more stably responds to changes in the position of the sun. it can. However, in such a solar panel, a shadow is generated on the side opposite to the light receiving surface and a part of the side surface with respect to the surface that receives sunlight in the early morning. The shadowed portion is irradiated with scattered light, so that the power generation effect is lower than that of direct light. Therefore, improvement of the power generation efficiency when the solar panel is shaded has been desired.

  Therefore, the present invention has been made in view of such problems, and is a combined power generation that combines solar power generation and wind power generation, which improves power generation efficiency by increasing the rotational efficiency of the windmill and the light receiving efficiency to the solar panel. An object is to provide an apparatus.

As shown in FIG. 4, the outer ring hub 61 has openings 610 between the reinforcing ribs 64 so that the wind 76 is evenly blown between the variable blades 65A and 65B.

  FIG. 5 is a side view showing a state where the variable blades 65A and 65B of the variable blade mechanism 62 are opened, and FIG. 6 is a side view showing a state where the variable blade of the variable blade mechanism 62 is closed on the opposite side of the wind blowing position. FIG. As shown in FIGS. 5 and 6, the variable blade mechanism 62 is roughly a pair of variable blades 65 </ b> A and 65 </ b> B as wind receiving members with one end attached to both sides of the outer ring hub 61 and a variable opening angle. An overopening prevention plate 67 (see FIG. 7A) for restricting the maximum opening angle of the variable blades 65A and 65B, and an opening angle adjusting plate for restricting the minimum opening angle provided inside the variable blades 65A and 65B. 68 (see FIG. 7B). The excessive opening preventing plate 67 and the opening angle adjusting plate 68 are fixed to the outer ring hub 61 with screws while the outer ring hub 61 is inserted.

  As shown in FIGS. 8A and 8B, the variable blades 65A and 65B have a symmetrical shape, one of the side walls is a fan shape, and the other side wall is a triangular shape. The one side wall is formed higher than the other side wall, and a loose hole 69 having an opening groove is provided along the arc in the vicinity of the sectoral arc. The variable blade 65A shown in FIG. 8 (a) and the variable blade 65B shown in FIG. 8 (b) are combined as shown in FIGS. 5 and 6, and each loose hole 69 is shown in FIG. 7 (c). A washer support bar 40 is loosely fitted, and this washer support bar 40 is screwed and fixed to the outer ring hub 61 by a coupling fitting 41. When the wind 76 is blown from the right side shown in FIG. 5, the variable blade 65A, 65B is guided by the coupling bracket 41 according to the wind pressure and the air volume, and moves up and down to open the variable blade mechanism 62 having the above configuration.

The air receiving opening 631 has, for example, a 140 ° opening in the horizontal direction, and a partition plate 633 having a curved surface is provided in the middle thereof. Since six such air collecting ducts 63 are disposed as a whole, it is possible to collect winds from all directions and guide them to the variable blade mechanism 62 installed in the subsequent stage. Since the wind collected by one of the wind collecting ducts 63 is blown to the pair of variable blades 65A and 65B, the wind receiving pressure of the variable blades 65A and 65B becomes extremely strong, and the strong force for rotating the outer ring hub 61 is strong. A rotational force can be obtained.

  FIG. 10 is a front view of the variable blade wind turbine 6 of the wind turbine generator 3 of FIG. In FIG. 10, the variable blade mechanism 62 in front of the rotating ring 10 is not shown in order to make the configuration of the rotating ring 10 easy to understand. FIG. 11 is a perspective view showing details of the rotating ring 10. The rotating ring 10 is a ring-shaped member having a length that reaches the vicinity of the inside of the variable blades 65A and 65B (the center side of the outer ring hub 61), and is arranged vertically with the outer ring hub 61 interposed therebetween, and the outer ring hub 61. It is fixed with screws on both sides. Of the winds blown between the variable blade 65A and the variable blade 65B by providing the rotating ring 10, the wind going toward the center of the outer ring hub 61 is the space between the variable blade 65A and the variable blade 65B. Since it is trapped in the wind, the wind receiving efficiency can be increased. Note that the shape of the rotating ring 10 is not limited to a cylindrical shape, and may have an outer shape such as an octagon.

  Here, instead of the variable blade wind turbine 6 constituting the wind power generator 3, a fixed acute angle inclined wind turbine 9 shown in FIG. 12 (plan view) and FIG. 13 (front view) may be used.

Is attached. With this configuration, when the wind 76 is received from the direction of the opening, the pyramidal on-off valve 73 is pressed by the wind pressure and receives the wind without any gap. On the other hand, when the pyramidal paddle wind turbine 7 receives the wind 76 and reaches a position rotated about 90 °, the wind 76 is blown from the opposite side of the opening of the pyramidal paddle 72, so the pyramidal open / close valve 73. Swings around the hinge 74 by the wind pressure, and the wind escapes from the gap generated by the swing. As a result, the wind pressure resistance in the rotation direction is reduced.

[Configuration of the cup-type paddle windmill 8]
Next, the structure of the cup-type paddle wind turbine 8 will be described. 17 is a plan view showing the configuration of the cup-type paddle wind turbine 8, FIG. 18 is a front view thereof, and FIG. 19 is a sectional view thereof.

Here, the paddle 82 on the side where the wind is blown by the air collecting duct 63 and the cup-type on / off valve 83 form a wind receiving member. As shown in FIGS. 18 and 19, the upper part of the cup-type opening / closing valve 83 is swingably attached by a hinge 84, and performs the same operation as the pyramid-type paddle wind turbine 7 described above.

[Operation of combined power generator]
Next, the operation of the composite power generation apparatus 100 will be described separately for the solar power generation panel 20 and the wind power generation apparatus 3. The solar power generation panel 20 stores power in the secondary battery (not shown) in the battery box 4 by generating power when sunlight of a certain level or higher is obtained. Even when the solar power generation panel 20 is partially shaded due to the position of the sun, time, etc., solar light irradiation can be obtained by the reflecting mirror and wind collecting plate 22, so that power generation is performed efficiently.

[Operation of the photovoltaic power generation panel 20]
When a strong wind or gust from a typhoon or seasonal wind blows from the lower side of the photovoltaic power generation panel 20, the wind vent mechanism 21 is opened to release the blown strong wind or gust as shown in FIG. Therefore, accidents such as the solar power generation panels 20 and 20 being lifted or blown away by a typhoon or a seasonal wind are prevented in advance.

[Operation of wind turbine generator 3]
Next, operation | movement of the wind power generator 3 is demonstrated. First, the wind power generator 3 using the variable blade wind turbine 6 will be described. As shown in FIG. 5, the wind 76 from the horizontal direction is taken into a wind receiving port 631 of a wind collecting duct 63 (see FIGS. 1, 2, and 9) arranged to face the flow of the wind 76. . Since the air collecting duct 63 is narrowed toward the nozzle portion 632, the air collecting duct 63 is blown to the variable blades 65A and 65B of the variable blade mechanism 62 shown in FIG. The variable blades 65A and 65B are arranged on the outside of the opening angle adjusting plate 68 as shown in FIG. 6 when the wind force from the air collecting duct 63 is very small and when the wind 77 is blown from the opposite side of the opening. And an opening angle of about 40 °, and when the wind force from the air collecting duct 63 is large, the opening angle is close to 90 ° by contacting the inside of the excessive opening preventing plate 67. Thereby, the variable blade mechanism 62 rotates while changing the opening angle of the variable blades 65A and 65B in accordance with the wind force and the wind direction from the air collecting duct 63. Here, the variable blades 65A and 65B move up and down between the position shown in FIG. 5 and the position shown in FIG. 6 with the washer support rod 40 loosely fitted in the loose hole 69 as a fulcrum. The generator 60 generates power according to the rotational speed of the variable blade mechanism 62, and the battery in the battery box 4 is charged by the generated power output.

  Here, when the variable wing mechanism 62 rotates, the variable wings 65A and 65B on the opposite side to the variable wings 65A and 65B to which the wind 76 is blown, the pair of variable wings 65A and 65B in front of the variable wings 65A and 65B are thin arrows. The wind (air) 77 flowing in the direction indicated by (→) rotates in the clockwise direction while being pushed, and so-called wind pressure resistance is generated. However, the variable blades 65A and 65B in this portion have an opening angle of about 40 ° as shown in FIG. 6, and the wind passes through the gaps formed above and below the variable blades 65A and 65B. Therefore, the wind 77 existing in the space before and after the pair of variable blades 65A and 65B does not form wind pressure resistance that weakens the rotation of the variable blade mechanism 62, so that power generation efficiency can be improved.

[Operation of the fixed acute angle inclined wind turbine 9]
Next, the wind power generator 3 using the fixed acute-angle inclined windmill 9 shown in FIGS. 12 and 13 will be described.

(See FIG. 13). In this fixed acute-angle inclined wind turbine 9, the fixed blades 91A and 91B have a fixed angle (120 °) unlike the variable blade wind turbine 6, but the fixed blades facing the nozzle portion 632 from the nozzle portion 632 of the air collecting duct 63 are fixed. The fixed acute-angle inclined wind turbine 9 rotates at a rotational speed corresponding to the wind force and the air volume of the wind blown on 91A, 91B, and a power generation output corresponding to this is obtained by the generator 60. The battery is charged.

[Operation of Pyramid Paddle Windmill 7]
Next, the wind power generator 3 using the pyramid type paddle windmill 7 will be described with reference to FIGS. 14 and 16. In this pyramid type paddle wind turbine 7, the wind taken in by the air collecting duct 63 is used as the wind 76 on the wind receiving member composed of the paddle 72 and the pyramid type on-off valve 73 disposed facing the nozzle portion 632 of the air collecting duct 63. Sprayed (see FIG. 16A).
