DESCRIPTION OF EMBODIMENTS

[0038] Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 3.

[0039] A wind turbine power generation device of the present invention includes a wind turbine generator 5 including a rotating disk 1, a wind turbine 2, a generator 3, and a wind collection body 4.

[0040] The rotating disk 1 is supported via a plurality of rollers 7 arranged on a fixed base 6, and is configured to be rotatable about a center C thereof as an axis. Furthermore, a central pillar 8 is provided at the center C. The central pillar 8 is configured to be rotatable by a bearing 9 provided on the fixed base 6.

[0041] The wind turbine generator 5 has a configuration in which the wind turbine 2 and the generator 3 are arranged inside the wind collection body 4. The wind collection body 4 includes a front wind collection body 11 whose cross-sectional area is formed to be reduced linearly or curvilinearly between a wind flow inlet 10 and a position where the wind turbine 2 is installed, and a rear wind collection body 13 whose reduced cross-sectional area is formed to be increased linearly or curvilinearly between the position where the wind turbine 2 is installed and a wind flow outlet 12 or to maintain the same cross-sectional area, and has a substantially rectangular cross section having a short side portion 14 and a long side portion 15.

[0042] Furthermore, as shown in FIGS. 3 and 6, a distance between the wind turbine 2 and the long side portion 15 of the wind collection body 4 is minimized, a ratio of the short side portion 14 and the long side portion 15 of the wind collection body 4 is set to 1 to 10 times, and a ratio of a short side portion 21 and a long side portion 22 of an outlet portion of the rear wind collection body 13 is set to 1 to 10 times. The wind collection body 4 is used in horizontal long or vertical long according to an installation place of the present wind turbine power generation device.

[0043] Furthermore, a wind dispersing portion having a shape that disperses wind outside the wind collection body 4 and increases a contact area between the wind outside the wind collection body 4 and wind inside the wind collection body 4 is provided at a mouth edge of the wind flow outlet 12 of the wind collection body 4. FIG. 7 illustrates cutout protrusion dispersing portions 16. The shape of the wind dispersing portion is not limited. For example, a star-shaped dispersing portion illustrated in FIGS. 8A, 8B and 8C, a flange-shaped dispersing portion illustrated in FIG. 9, a gear-type dispersing portion illustrated in FIG. 10, or other shapes may be used.

[0044] In the present invention, the wind turbine 2, the generator 3, and the wind collection body 4 constituting the wind turbine generator 5 are supported at a point away from the center C of the rotating disk 1. Furthermore, the wind turbine generator 5 is supported with the wind flow inlet 10 of the wind collection body 4 facing the center C of the rotating disk 1.

[0045] In the embodiment of the drawings, the wind turbine generator 5 is supported by a support pillar 18, and both ends of a main shaft 17 of the wind turbine generator 5 are supported on the rotating disk 1 by a main shaft pillar 19 provided separately from the central pillar 8.

[0046] In the above configuration, the rotating disk 1 is rotatable. Therefore, when wind hits the wind turbine generator 5, the rotating disk 1 rotates, and at the same time, the wind turbine generator 5 is moved to the leeward side of the wind from the center C of the rotating disk 1, and the wind flow inlet 10 of the wind collection body 4 faces a wind direction in all directions.

[0047] Since the wind flow inlet 10 of the wind collection body 4 of the wind turbine generator 2 always faces the wind direction, the wind turbine 10 is always rotated while capturing the wind, a rotation efficiency of the generator 3 is improved, and a power generation efficiency is improved.

[0048] Next, an embodiment of FIGS. 4 to 6 will be described. Note that reference numerals common to those in FIGS. 1 to 3 are denoted by the same reference numerals.

[0049] In this embodiment, the wind turbine 2 and the generator 3 are supported by the central pillar 8 and the support pillar 18 of the wind turbine generator 5, and both ends of the wind collection body 4 are supported by support pillars 20, thereby improving a strength against wind power.

INDUSTRIAL APPLICABILITY

[0050] Since the wind turbine power generation device exerts a yaw function to face the wind direction, and the rotation efficiency of the wind turbine and the generator can be improved to increase generated power, the application field thereof is vast.
