[0009] Preferred embodiments of the present invention will be described with reference to the accompanying drawings. Note that the embodiments described below do not limit the scope of the present invention as defined in the claims. Furthermore, not all of the configurations described below are essential requirements of the present invention. [Example 1]

[0010] Figures 1 to 6 show Embodiment 1 of the present invention. As shown in Figure 1, the renewable energy power generation system 1 of this embodiment is equipped with a support column 3 that stands upright on a main foundation 2 made mainly of concrete or the like, which is installed on the installation surface G of the power generation system 1, and the power generation equipment 4 is supported by this support column 3.

[0011] A wind guide unit 5 is installed on the upper part of the main body foundation 2.

[0012] The wind guide section 5 is formed in the shape of a roughly frustum (or truncated cone), and the wind guide section 5 may also be a frustum of a cone other than a square pyramid, such as a cone, triangular pyramid, or pentagonal pyramid.

[0013] The outer surfaces of each side 6 of the wind guide section 5 are inclined upward (inclined with respect to the installation surface G), and the wind guide section 5 guides the airflow that has flowed towards the wind guide section 5 along the installation surface G toward the apex of the wind guide section 5.

[0014] The wind guiding section 5 is equipped with plate-shaped wind-stopping frames 7 that are erected radially from the center of the wind guiding section 5, extending from the apex of the wind guiding section 5 to the middle of each side 6, along the boundary line where each side 6 is adjacent to another side 6. The wind-stopping frames 7 are erected so that their surfaces are perpendicular to the installation surface G, that is, parallel to the vertical direction.

[0015] The aforementioned support column 3 is erected vertically from the installation surface G so as to connect the center of the main foundation 2 to the center of the wind guide section 5. The basic structure of the support column 3 uses reinforced concrete assembly and has sufficient strength to support the entire power generation equipment 4.

[0016] The aforementioned power generation facility 4 is a power generation facility that utilizes renewable energy, and includes a wind power generation section 8 and a solar power generation section 9.

[0017] The wind power generation unit 8 comprises an intake unit 10, an exhaust unit 11, a generator 13 with a rotating blade 12 between the intake unit 10 and the exhaust unit 11, and a casing 14 made of a hollow housing that encloses the rotating blade 12 and sends wind from the wind collection unit 24 (described later) to the rotating blade 12.

[0018] On the upper part of the casing 14, the aforementioned exhaust part 11, which is a hollow housing that communicates with the inside of the casing 14 and discharges the air inside the casing 14 to the outside, is arranged. The exhaust part 11 has a vent hole 15, and in the exhaust part 11, the air sent from the inside of the casing 14 is discharged to the outside through the vent hole 15.

[0019] The intake part 10 includes a lower receiving plate 16 and an upper receiving plate 17.

[0020] The lower receiving plate 17 has a basic shape of a hollow cylindrical shape with the upper base, which is the upper bottom surface of a push table (or a truncated cone), and the lower base, which is the lower bottom surface, both opened. The taper of the side surface 18 has an inclination such that the diameter expands from the upper base to the lower base (or the diameter contracts from the lower base to the upper base).

[0021] Along the boundary line between the side surfaces 18 of the lower receiving plate 16, a plate-shaped outer frame 19 is erected radially from the lower end to the middle section of the boundary line.

[0022] A plate-shaped central frame 20 is erected radially from the middle section to the upper end in the center of each side surface 18 of the lower receiving plate 16.

[0023] Between the outer frame 19 and the central frame 20 of each side surface 18 of the lower receiving plate 16, a plate-shaped inner frame 21 is erected radially from the lower end to the middle section.

[0024] These outer frame 19, central frame 20, and inner frame 21 are a rectifying part 22 that has the effect of a rectifying plate for arranging the flow of air taken into the intake part 10 and guided to the air collecting part 24 described later.

[0025] The upper support plate 17 has almost the same basic shape as the lower support plate 16, and is a hollow cylindrical shape with the upper and lower bases of the thrust base (or truncated pyramid) open. The taper of the side surface 23 is sloped so that the diameter widens from the upper base to the lower base (or narrows from the lower base to the upper base). In this embodiment, both the lower support plate 16 and the upper support plate 17 are thrust bases as truncated pyramids of a square pyramid, but they may also be truncated pyramids of a cone, triangular pyramid, or pentagonal pyramid, etc.

[0026] The upper end of the support column 3 is provided with a wind collection section 24 for collecting the air taken in by the intake section 10 and guiding it to the wind power generation section 8.

[0027] The wind collection section 24 consists of a hollow lattice body with a cubic shape, having frames on each side and openings on the top, bottom, and sides, with the bottom side fixed to the support column 3.

[0028] Here, the configuration of the intake section 10 for taking in air will be described. The intake section 10 is equipped with multiple intake structures consisting of a first air intake port 29 and a second air intake port 30, which will be described later. The relationship between the intake section 10 and the lower receiving plate 16 and the upper receiving plate 17 will be described in detail below.

[0029] The upper opening edge 25 that forms the upper opening of the lower receiving plate 16 is fixed to the bottom frame of the wind collection section 24.

[0030] The lower opening edge 26 that forms the lower opening of the lower receiving plate 16 is positioned at the height of the upper part of the wind guide section 5 (the upper end of the wind stopper frame) or higher.

[0031] The upper opening edge 27 that forms the upper opening of the upper receiving plate 17 is fixed to the upper frame of the wind collection section 24.

[0032] The lower opening edge 28 that forms the lower opening of the upper receiving plate 17 is set to be positioned below the bottom frame of the wind collection section 24.

[0033] The first air intake 29 is made of the lower opening edge 26 of the lower support plate 16, and the second air intake 30 is made of the gap between the upper support plate 17 and the lower support plate 16.

[0034] The solar power generation unit 9 comprises a top power generation unit 31, an upper power generation unit 32, and a lower power generation unit 33.

[0035] The rooftop power generation unit 31 consists of solar panels installed above the exhaust unit 11 and is installed at an angle that takes into account the maximum power generation efficiency at the installation site of the power generation system 1. The rooftop power generation unit 31 is also equipped with multiple ventilation holes. The solar panels of the rooftop power generation unit 31 may be circular (see Figure 5), square (see Figure 3), or other shapes such as triangles or other polygons.

[0036] The upper power generation unit 32 consists of solar panels installed on all sides 23 of the upper support plate 17, and the lower power generation unit 33 consists of solar panels installed on all sides 18 of the lower support plate 16.

[0037] The power generation system 1 is equipped with a main body reinforcement section 35 and a roof reinforcement section 36 to reinforce its structure.

[0038] The main body reinforcement section 35 consists of chains, wires, bracing materials, etc., that connect the four lower corners of the lower end of the lower support plate 16 to the installation surface G. The roof reinforcement section 36 consists of chains, wires, bracing materials, etc., that connect the roof power generation section 31 to the lower part of the casing 14.

[0039] The power generation system 1 with the above configuration will now be described. First, the wind power generation section 8 will be described. The wind F1 near the installation surface G rises along the side surface 6 of the wind guide section 5, rises through the first air intake 29 and into the interior of the lower receiving plate 16, and is guided to the wind collection section 24.

[0040] The rising wind F2 near the installation surface G and the wind F3 around the lower receiving plate 16 rise along the outer surface of the side 18 of the lower receiving plate 16, through the second air intake 30, and into the interior of the upper receiving plate 17, and are guided to the wind collection section 24. The upward force of the wind collected in the wind collection section 24 rotates the rotating blades 12 inside the casing 14, and this rotational force is transmitted to the generator 13 to generate electricity. The wind that has rotated the rotating blades 12 is then discharged to the outside through the exhaust section 11.

[0041] Next, the solar power generation unit 9 generates electricity using sunlight that shines on the top power generation unit 31, the upper power generation unit 32, and the lower power generation unit 33.

[0042] The electricity generated by the wind power generation unit 8 and the solar power generation unit 9 is supplied to various electrical equipment in the greenhouse cultivation facility H as shown in Figure 6, making it possible to achieve self-sufficiency in electricity for greenhouse cultivation.

[0043] The roof-mounted power generation unit 31 is equipped with wind vents 34 and roof reinforcement 36, which prevents damage to the roof-mounted power generation unit 31 from typhoons, storms, or gusts of wind such as wind discharged from the exhaust unit 11.

[0044] The main body reinforcement section 35 prevents damage to the lower support plate 16 and the power generation equipment 4 from gusts of wind such as typhoons and storms.

[0045] In this embodiment, by providing a wind power generation unit 8 in which a rotating blade 12 is arranged between an intake unit 10 and an exhaust unit 11, and a solar power generation unit 9 in which a solar panel is installed on the outer surface of the intake unit 10 of the wind power generation unit 8, it is possible to provide a renewable energy power generation system 1 that simplifies the combination of wind power generation and solar power generation and increases the amount of power generated or improves the power generation efficiency.

[0046] In this embodiment, the intake section 10 comprises a lower receiving plate 16 and an upper receiving plate 17 positioned above the lower receiving plate 16. It also includes a first air intake port 29 that takes in air from inside the lower receiving plate 16 and a second air intake port 30 that takes in air from between the lower receiving plate 16 and the upper receiving plate 17. This configuration allows for effective air intake by taking in both lower and upper winds, thereby improving the power generation efficiency of the wind power generation system.

[0047] Furthermore, in this embodiment, by arranging the solar panels on the outer surface of the lower support plate 16 and the outer surface of the upper support plate 17, the combination of the wind power intake structure and solar power generation can be simplified.

[0048] Another effect of this embodiment is that the rising airflow of air flowing towards the wind collection section 24 cools the heat of the solar panels installed on the outer surfaces of the sides 18 and 23 of the lower receiving plate 16 and the upper receiving plate 17, thereby suppressing the decrease in power generation efficiency due to the rise in temperature of the solar panels during the summer.

[0049] Furthermore, in the summer, the temperature rise of the solar panels in the upper power generation section 32 and the lower power generation section 33 causes the temperature around each air intake 29 and 30 to rise, while the exhaust section 11 is shaded by the upper power generation section 31, blocking direct sunlight. If a temperature difference occurs between the intake section 10 and the exhaust section 11, the upward airflow collected towards the wind collection section 24 by the chimney effect is further promoted, which may improve the efficiency of wind power generation.

[0050] The present invention is not limited to the above embodiments, and various modifications can be implemented within the scope of the gist of the present invention. [Explanation of Symbols]
