(57) [Summary] [Purpose] When wind power generation is performed using a wind turbine, the wind power is efficiently converted into electric power and the blades can be easily manufactured. [Structure] The blades of a wind turbine have an arc-shaped cross section.
Description
【０００１】[0001]
この考案は風力を利用して風車を回して発電をしようとするときに使うもので ある。 This device is used when using wind power to rotate a wind turbine to generate electricity.
【０００２】[0002]
従来の風車の羽根は第５図のように飛行機の羽根のように複雑な形に作られて いた。しかし、形が複雑なために製作するのが容易でく重量も有り、又あまり 多くの羽根が使われることもなく、２〜４枚の羽根が普通である。従って風を 効率よく電力に変えるのが難しかった。 The blades of a conventional wind turbine are made in a complicated shape like the blades of an airplane as shown in Fig. 5. However, due to its complicated shape, it is easy to manufacture, it is heavy, and not many blades are used. Therefore, it was difficult to efficiently convert wind into electricity.
【０００３】[0003]
この考案では、羽根を簡単に、大量に作ることを、又、効率よく風力を電力に 変えることを考えた。 In this invention, we considered to make a large number of blades easily and to efficiently convert wind power into electricity.
【０００４】[0004]
風車の羽根になる部分（１）を円弧状にする。 The part (1) that becomes the blade of the wind turbine is formed into an arc shape.
【０００５】[0005]
第２図は第１図のＡ−Ａ’の断面図、第３図は第５図Ｂ−Ｂ’の、第４図は第 ６図のＣ−Ｃ’の断面図であるが第２図、第３図、及び第４図で羽根に空気が →（２）、→（３）、の 様に流れると←（５）の方向に揚力が起きる。 2 is a sectional view taken along the line AA 'in FIG. 1, FIG. 3 is a sectional view taken along the line BB' in FIG. 5, and FIG. 4 is a sectional view taken along the line CC 'in FIG. , Fig. 3 and Fig. 4, when air flows in the blades as → (2), → (3), lift force occurs in the direction of ← (5).
【０００６】[0006]
第７図はこの羽根を使用した風車の例であるが、この様に数枚以上、又２段以 上にして、効率よく風力を利用することができる。 FIG. 7 shows an example of a wind turbine using this blade, but it is possible to efficiently use the wind power by using several blades or two or more stages in this way.
【０００７】[0007]
【考案の効果】 この様な羽根を使用した風車であれば効率をあまり損なうことなく羽根の重量 を減ずることができる。又、風車の重量が軽くなるとそれを支える土台や塔な ど全体の重量を減ずることができる。EFFECTS OF THE INVENTION A wind turbine using such blades can reduce the weight of the blades without significantly impairing efficiency. Also, as the weight of the wind turbine becomes lighter, it is possible to reduce the overall weight of the foundation and towers that support it.
