Embodiments for Carrying out the Invention

[0017] Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. However, the present invention is not limited to the following description, and various modifications and changes can be made by those skilled in the art based on the gist of the invention described in the claims or disclosed in the embodiments for carrying out the invention. Such modifications and changes are also included in the scope of the present invention. Also, all documents mentioned in this specification are incorporated herein by reference in their entirety.

[0018] FIG. 1 is a schematic diagram showing the state of the first form 1 of the balloon-shaped vertical vortex windmill of the present invention. In the first form 1, the fluid is discharged and it is in a compact state, and as shown in FIG. 1, it can be folded and easily transported by putting it in a container C or the like.

[0019] Figure 2 is a schematic diagram showing the second form 2 of the balloon-type vertical vortex wind turbine of the present invention. In the second form 2, fluid is injected to create a vertical vortex wind turbine, and power generation is possible by attaching a generator or the like to the rotating shaft. Since only fluid is injected, the wind turbine can be made larger, and an increase in power generation capacity can be expected. Because it is easy to transport as in the first form 1, it is useful, for example, when electricity is needed temporarily, such as at camps or events.

[0020] A balloon-type vertical vortex wind turbine can be formed by creating a sheet-like structure (first form 1) from a material such as thermoplastic polyurethane, polyvinyl chloride, polyvinyl chloride, polyethylene, or polyvinyl, and then joining predetermined positions together so that it takes on a predetermined shape (second form 2) when inflated by injecting a fluid. The fluid may include gases such as air or liquids such as water.

[0021] In order to rotate the rotating body 3 of a vertical vortex wind turbine, the wake object 4 needs to have a flat surface where it intersects with the rotating body 3. With a typical balloon structure, it is difficult to form a flat surface when fluid is injected. Therefore, in this embodiment, for example, the wake object 4 is made of a member having a drop-stitch structure. A drop-stitch structure is a structure in which a predetermined surface of the fabric and the opposite surface facing the predetermined surface are joined together using threads made by bundling highly durable fibers, and when fluid is injected, countless threads pull the fabric on the opposing surfaces. This makes it possible to inject fluid into the member at high pressure, achieving high rigidity and stability, and also makes it possible to maintain predetermined shapes such as the flat surface of the wake object 4 necessary for the rotation of the vertical vortex wind turbine when fluid is injected. Other parts such as the rotating body 3, which do not have a flat surface, can be realized with a typical balloon structure.

[0022] A balloon-type vertical vortex wind turbine can be inflated by injecting fluid from an inlet (not shown), as shown in Figure 3, for example. A manual or electric pump P can be used to inject the fluid.

[0023] When fluid is injected, a second form 2 of the components, such as the rotating body 3 and the wake object 4 shown in Figure 4, can be formed.

[0024] As shown in Figure 5, the vertical vortex wind turbine is completed by assembling the parts of the second form 2 into which the fluid has been injected. Figure 5 shows how the rotating body 3 is assembled onto the rotating shaft 5.

[0025] The configuration examples of the second embodiment 2 of the present invention will be described in three parts, divided into the first to third embodiments. Although the vertical vortex wind turbine of the present invention is balloon-shaped, for the sake of explanation, schematic diagrams showing the configuration will be used.

[0026] <First Embodiment> The vertical vortex wind turbine of this embodiment has the configuration described in Patent Document 1. Therefore, all the configurations described in Patent Document 1 are applicable to this embodiment.

[0027] Figures 6 and 7 show the schematic configuration of the vertical vortex wind turbine of this embodiment. The vertical vortex wind turbine comprises a ring-shaped first wake body 6 and a cylindrical first rotating body 8 that is pivotally supported by a rotating shaft 7 and positioned upstream of the first wake body 6.

[0028] The first wake object 6 has a first plane 9 that intersects substantially perpendicularly with respect to the fluid flow direction F. The first wake object 2 is formed from a ring-shaped plate. In this embodiment shown in the drawings, the first wake object 6 has a constant ring width W around its entire circumference. The first wake object 6 can also be a cylindrical shape with a greater thickness in a direction parallel to the fluid flow direction F, rather than a ring-shaped plate. The first wake object 6 is made from a member having a drop-stitch structure in order to form the first plane 9 when fluid is injected.

[0029] The rotating shaft 7 is approximately parallel to the fluid flow direction F. The first downstream object 6 is positioned concentrically with the rotating shaft 7.

[0030] The first rotating body 8 is pivotally supported by the rotating shaft 7 and positioned upstream of the first wake object 6, and rotates about the rotating shaft 7 in a first rotation plane 10 that intersects substantially perpendicularly with the fluid flow direction F. The first rotating body 8 has a first intersection portion 11 that intersects the first plane 9 at a distance upstream of the first wake object 6. In this embodiment, two first intersection portions 11 are provided, but the first rotating body 8 can be rotated with one or more. Note that multiple first rotating bodies 8 can be provided.

[0031] The first plane 9 and the first plane of revolution 10 are approximately parallel.

[0032] The rotation of the first rotating body 8 can be controlled by appropriately changing the first separation gap S1 between the first rotating body 8 and the first plane 9. The first separation distance S1 may be changed according to wind speed, etc. By selecting the first separation gap S1 that is optimal for the flow velocity conditions at the installation site, the lift force can be easily controlled, and if a generator or the like is attached to the rotating shaft 7, efficient power generation can be achieved.

[0033] <Second Embodiment> The vertical vortex wind turbine of this embodiment has the configuration described in Japanese Patent Application No. 2023-160061. Therefore, all the configurations described in Japanese Patent Application No. 2023-160061 are applicable to this embodiment.

[0034] Figures 8 and 9 show the schematic configuration of the vertical vortex wind turbine of this embodiment. In addition to the configuration of the first embodiment, the vertical vortex wind turbine includes a cylindrical second rotating body 12 that is pivotally supported by the rotating shaft 7 and positioned downstream of the first wake body 6.

[0035] The second rotating body 12 rotates around the rotating shaft 7 in a second rotational plane 13 that intersects substantially perpendicularly with the fluid flow direction F. The second rotating body 12 has a second intersection portion 15 that intersects the back surface 14 of the first plane 9, separated downstream of the first downstream object 6, and the back surface 14 of the first plane 9 and the second rotational plane 13 are substantially parallel. The back surface 14 of the first plane 9 is also a plane. In this embodiment, two second intersection portions 15 are provided, but the second rotating body 12 can be rotated with one or more. Note that multiple second rotating bodies 12 can be provided.

[0036] The rotation of the second rotating body 12 can be controlled by appropriately changing the second separation gap S2 between the second rotating body 12 and the back surface 14 of the first plane 9. The second separation distance S2 may be changed according to wind speed, etc. By selecting the second separation gap S2 that is optimal for the flow velocity conditions at the installation site, the lift force can be easily controlled, and if a generator or the like is attached to the rotating shaft 7, efficient power generation can be achieved.

[0037] <Third Embodiment-1> The vertical vortex wind turbine of this embodiment has the configuration described in Japanese Patent Application No. 2024-176892. Therefore, all the configurations described in Japanese Patent Application No. 2024-176892 are applicable to this embodiment.

[0038] Figures 10 and 11 show the schematic configuration of the vertical vortex wind turbine of this embodiment. In addition to the configuration of the first embodiment, the vertical vortex wind turbine includes a second wake body 17 positioned upstream of the first rotating body 8 and having a third plane 16 that intersects substantially perpendicularly with respect to the fluid flow direction F.

[0039] The first plane 9, the first plane of revolution 10, and the third plane 16 are approximately parallel.

[0040] The second wake object 17 is formed from a ring-shaped plate. In this embodiment shown in the drawings, the second wake object 17 has a constant ring width W' around its entire circumference. The second wake object 17 can also be a cylindrical shape with a greater thickness in the direction parallel to the fluid flow direction F, rather than a ring-shaped plate. The second wake object 17 is made from a member having a drop-stitch structure in order to form a third plane 16 when fluid is injected.

[0041] The rotation of the first rotating body 8 can be controlled by appropriately changing the third separation gap S3 between the first rotating body 8 and the back surface 21 of the third plane 16, together with the first separation gap S1. The back surface 21 of the third plane 16 is also a plane. The first and third separation distances S1 and S3 may be changed according to wind speed, etc. By selecting the first and third separation gaps S1 and S3 that are optimal for the flow velocity conditions at the installation site, the lift force can be easily controlled, and if a generator or the like is attached to the rotating shaft 7, efficient power generation can be achieved.

In this embodiment, two third intersections 20 are provided, but the third rotating body 19 can be rotated with one or more. Note that multiple third rotating bodies 19 can be provided.

[0046] Furthermore, in the balloon-type vertical vortex wind turbine of this embodiment, the second form 2 vertical vortex wind turbine is further comprising a second rotating body 12 that is pivotally supported on a rotating shaft 7 and positioned downstream of the first wake object 6, and rotates about the rotating shaft 7 in a second rotational plane 13 that intersects substantially perpendicularly with the fluid flow direction F, and the second rotating body 12 has a second intersection portion 15 that intersects with the back surface 14 of the first plane 9 at a distance downstream of the first wake object 6, and the back surface 14 of the first plane 9 and the second rotational plane 13 are substantially parallel.

[0047] Furthermore, in the balloon-type vertical vortex wind turbine of this embodiment, the second form 2 vertical vortex wind turbine is positioned upstream of the first rotating body 8 and further comprises a second wake body 17 having a third plane 16 that intersects substantially perpendicularly with respect to the fluid flow direction F, the first plane 9, the first rotation plane 10, and the third plane 16 are substantially parallel, and the second wake body 17 is made of a member having a drop-stitch structure.
