- the technical problem of the present invention focuses on such problems, reduces the force acting in the direction opposite to the rotation direction, and makes the blade shape effective in the rotation direction.
- the shape of the blade which is the life of the wind turbine for vertical axis wind power generator, focuses on the back side or back of the blade which usually can not be caught although the external dimensions differ depending on the output of the wind power generator. It has a shape that can be captured.

- the wing provided outside the wing thickness variation position on the central axis side of the wing may be openable and closable via a hinge means, but may be fixed in an open state.
- the wind pressure reflected by the concave surface is also applied, and the wind pressure is received on a wider surface, so that the wind pressure can be used more effectively. Therefore, power can be generated even when the wind is weak.

- the concave surface 3 of the blade 1 and the struts By generating the lift force A using the lower concaved curve 5 with the lower side 4, an efficient amount of power generation can be obtained. That is, since it succeeds in generating twice the power with one wind, and unlike an ordinary wind power generator, it is possible to start rotation with a slight wind, a strong wind enabling power generation is generated. At the same time, it is possible to start power generation instantaneously with a short time difference, enabling highly efficient power generation.

Focusing on 4, as shown in FIG. 6, a bag shape 7 that can receive air resistance more easily than the concave curved surface 3 inside the blade 1, and generates from the blade 1 rotated by the wind received on the surface of the blade 1 by the drag R It is possible to obtain a more efficient rotational movement by receiving the air flow together with the blades 1 rotated by the rotational movement of the lift force A and the strut (girder) 4 according to the present invention and pushing from behind. The rotational effect of the pressure received by the bag shape 7 becomes stronger as the rotational radius is larger.
- the area of the strut (girder) 4 itself is small [width 140 ⁇ 45], so the bag (concave concaved curve 5) with strut (girder) 4 efficiently receives wind.

- the open / close wing M has a plate-like shape, and the front end thereof is attached to the outer surface of the wing 1 at the wing thickness variation position via the hinge H. Therefore, as shown in FIG. 7 (1), when the blade 1 is rotating toward the wind W, the open / close wing M is closed by the wind pressure, but as shown in FIG.
- the open / close wing M attached to the lower surface of the strut 4 of FIG. 6 with the hinge H opens and closes as shown by a chain line, but shows both a closed state and an open state.
- the angle when the open / close wing M opens is about 30 degrees or less, it is rather a resistance, so it is necessary to provide a stopper so as not to open too much.
- the strut in FIG. 8 is an example in which a fixed wing f fixed from the beginning integrally in an open state is provided, and the open / close wing M in FIG. 6 is fixed open.
- a dimension is an example.
- the open / close wing M of the wing 1 of FIG. 7 may not be the hinge H, but may be an open fixed structure.
- the wind turbine (vane) at the outer end has a convex arc shape on the outer surface and a concave arc whose inner surface has a smaller radius than the outer surface.

Abstract
Description
垂直軸型の風車では、特許文献1などが知られている。特許文献1は簡易構造のサボニウス風車の特徴を極力犠牲にすることなく、低回転数域で高トルクを発生すべく、風車の羽根の外端寄りの位置において、羽根外端寄りが受風凹曲面側に相対的にずれるように、逆Z字状又はZ字状の階段状に屈曲させた構造であり、階段状の段差板の外面で受ける風力は、本来の凹曲面で受ける風力を補助する作用をする。その結果、低回転数域でも高トルクを発生する。
本発明の技術的課題は、このような問題に着目し、回転方向と逆方向に作用する力を少なくし、回転方向に効果的に作用する羽根形状とする。
この羽根の水平断面形状は流線形状をしており、その流線形の前側45±10%に対し後側は、外側面が凸の円弧状をしているが、中心軸側は、前記羽根の後端から中心軸側の羽根厚変異位置まで連続した閉じた凹円弧面になっており、しかも羽根厚が、全寸から次第に薄くなっていることを特徴とする風力発電機用の風車である。
状の中空部に補強部材を挟むと共に、その前頭部より60±10%の位置より後側は、上側面が流線形の一部を成す凸の円弧状をしており、下側の面が除去されて、後ろ向きの開口を残した構造を特徴とする請求項1から請求項4までのいずれかに記載の風力発電機用の風車である。
その特徴の一つである抗力Rと同時に揚力Aも生み出す方法は、 羽根と、 図2に示すストラット4其々の下側の形状を凹湾曲にする事により、一度の風の力で二倍の風の力を生み出せる斬新な垂直軸型風力発電機用の風車( 羽根) となっている。
また、本発明である垂直軸型風力発電機用風車 (羽根 )の特徴の一つでもある風車 (羽根 )の製造に関しては、材質は軽量で強度のあるアルミ合金 (AL -5025 )を使用し、図4、図5のように全体のほぼ中心部から前後に二分割された押圧工法又は引き抜きにより、パイプ形状の中空形状に整形されている。
しかし、一枚に組み立てられた羽根1の重量が重いため (機種により異なるが )、軽量化を図る目的で、後方部22の一部分を複数均等に刳り貫き加工し、重量の低減を図っている。すなわち、後方の薄い部分23は、中実に徐々に薄くする。
なお、この刳り貫き加工された後方部22の空洞を塞ぐための作業として、前後二種類の羽根を合体組合せ作業完了後、0.5mm 厚のアルミ板24、25で上下を塞ぐ事が必要なため、前後羽根は最初から段差をつけて成型されている。
羽根1及びストラット4は軽量化のために中空にして、強度向上の目的で補強部材Sを挟んだ構造にしている。外気に露出する表面板は、板材を組立てたり加工したりして製造する。
なお、羽根1の後内側の凹曲面3と1番目及び必要に応じて2番目の補強部材Sを省いてストラット4と同様な袋形状も可能である。
さらに回転移動して、開閉翼Mが閉じる方向の風圧を前端から受けるようになると、開閉翼Mが閉じて、羽根1を押し戻す方向の力は最小となる。
なお、羽根1の凹曲面3で反射して、開いた開閉翼Mに当たると、羽根1を前進させる方向に作用するので、風車はより円滑に回転する。また、凹曲面3で反射された風は、この開閉翼Mの無い部位で本発明の袋状ストラット4に導かれるので、風車の回転に寄与する。
なお、開閉翼Mが開く際の角度を約30度以下にすると、かえって抵抗となるので、あまり開き過ぎないようにストッパーを設ける必要がある。
図8のストラットは、開いた状態で初めから一体に固定された固定翼fを設けてあり、図6の開閉翼Mを開いて固定した例である。なお、寸法は一例である。
図7の羽根1の開閉翼MもヒンジHにしないで、開いた固定構造にしてもよい。
なお各機種により、羽根及びストラットの形状自体には大きな変化はないが、外形サイズは異なる。
