Description

本発明は、たとえば、小型風力発電装置に用いられるクロスフロー風車及び風力発電装置に関する。   The present invention relates to, for example, a crossflow wind turbine and a wind power generator used in a small wind power generator.

風車は、近年における環境問題の意識の高まりから、環境に影響を与える物質を発生させない風力発電などの動力源として注目を集めており、小型の羽根構造の風車から大型のプロペラ型の風車まで各種の構成のものが提案され実施されてきている。
しかし、大型のプロペラ型風車を用いる風力発電装置は、イニシャル費用が高価なこともあり市場導入は補助金等が頼みの綱である。 Wind turbines are attracting attention as a power source for wind power generation that does not generate substances that affect the environment due to increasing awareness of environmental issues in recent years. Various types of wind turbines, from small bladed wind turbines to large propeller type wind turbines, are attracting attention. The thing of the structure of this is proposed and implemented.
However, wind power generators using large propeller-type wind turbines are expensive in initial cost, and subsidies are the main reason for the introduction to the market.

そこで、大型のプロペラ型風車など他の風車に比べ、微風域での自力回転可能で回転効率が優れている点でクロスフロー風車が注目されている。
このクロスフロー風車としては、より微風域での回転効率をよくするために、ガイドベーンを設けるようにしたものが提案されている（特許文献１、２参照）。 Therefore, compared to other wind turbines such as large propeller type wind turbines, cross flow wind turbines are attracting attention because they can rotate by themselves in a light wind region and have excellent rotational efficiency.
As this cross-flow wind turbine, in order to improve the rotational efficiency in a fine wind region, a guide vane is provided (see Patent Documents 1 and 2).

しかし、上記のような従来のクロスフロー風車の場合、他の風車に比べ微風域での回転効率にすぐれているものの、風車本体がステンレス鋼で形成されているため、風車本体が重くまだまだ十分なものではない。
また、風車のイニシャルコストを削減するためには、製造原価の低下が必要不可欠であり、１つ１つの部材が大量生産、大量消費のプロセスに乗ることが必要である。しかしながら、世間は環境ブームとはいえ、イニシャルコストを数年のランニングコストで回収しきれない現状では、爆発的に売れる状況ではない。結果、部材はオーダーメード的にならざるをえない。まして、近年高騰している金属類を使用することや、手作業にてクロスフロー風車特有の数多い羽根体を１つ１つ作製して翼形状に加工していくことは、他の風車と比較してもコスト的に非常に不利である。 However, in the case of the conventional cross-flow wind turbine as described above, although the rotational efficiency in the light wind region is superior to other wind turbines, the wind turbine body is made of stainless steel, so the wind turbine body is heavy and still sufficient. It is not a thing.
Further, in order to reduce the initial cost of the wind turbine, it is indispensable to lower the manufacturing cost, and it is necessary for each member to enter a process of mass production and mass consumption. However, even though the world is in an environmental boom, it is not an explosive selling situation in which the initial cost cannot be recovered with the running cost of several years. As a result, the members must be made to order. In addition, the use of metals that have been soaring in recent years, and the production of many individual blades unique to crossflow wind turbines and processing them into blade shapes, compared to other wind turbines. However, it is very disadvantageous in terms of cost.

一方、風車での発電不足を補うために、太陽光パネルと併用したものも提案されている（特許文献３参照）が、太陽光パネルの設置スペースが必要となり大型化するとともに、製造コストもかかると言う問題がある。   On the other hand, in order to make up for the power generation shortage in the windmill, a solar panel combined with a solar panel has been proposed (see Patent Document 3), but the installation space for the solar panel is required, which increases the size and the manufacturing cost. There is a problem to say.

本発明は、上記事情に鑑みて、回転効率がよく、安価に製造することができるクロスフロー風車及び風力発電装置を提供することを目的としている。   In view of the above circumstances, an object of the present invention is to provide a cross-flow wind turbine and a wind turbine generator that can be manufactured at low cost with high rotational efficiency.

上記目的を達成するために、本発明にかかるクロスフロー風車は、中心軸周りに回転自在に支持された円盤状の回転板と、この回転板の周方向に等ピッチで回転板に立設された複数の羽根体とを有する風車本体を備えるクロスフロー風車において、
前記羽根体が、最外縁を前記回転板上の直径Ｒの仮想円に一致させた状態で回転板に立設されているとともに、内弧面を含む仮想円の直径ｒがＲ＞ｒ＞１／８Ｒの関係を満足する断面円弧状をした合成樹脂製の短冊状片から形成されていることを特徴としている。
また、本発明のクロスフロー風車は、短冊状片が押出成形加工された合成樹脂管を合成樹脂管の管軸を含む面に沿って２〜２０に等分割されて得られるようにすることが好ましい。さらに、風車本体の周囲を囲むようにガイドベーンを備えている構成、羽根体が、ゴム成分を含んだ耐衝撃性ポリ塩化ビニル系樹脂組成物で形成されている構成としてもよい。 In order to achieve the above object, a cross-flow wind turbine according to the present invention is provided with a disk-shaped rotating plate that is rotatably supported around a central axis, and is erected on the rotating plate at an equal pitch in the circumferential direction of the rotating plate. In a crossflow wind turbine comprising a wind turbine body having a plurality of blades,
The blade body is erected on the rotating plate with its outermost edge coinciding with the virtual circle of diameter R on the rotating plate, and the diameter r of the virtual circle including the inner arc surface is R>r> 1 It is characterized by being formed from a strip-shaped piece made of synthetic resin having a circular arc shape that satisfies the relationship of / 8R.
In the crossflow wind turbine of the present invention, a synthetic resin tube obtained by extruding a strip-shaped piece is equally divided into 2 to 20 along a surface including the tube axis of the synthetic resin tube. preferable. Furthermore, it is good also as a structure provided with the guide vane so that the circumference | surroundings of a windmill main body may be enclosed, and the structure by which the blade | wing body was formed with the impact-resistant polyvinyl chloride resin composition containing the rubber component.

上記のように、本発明のクロスフロー風車は、羽根体が、最外縁を前記回転板上の直径Ｒの仮想円に一致させた状態で回転板に立設されているとともに、内弧面を含む仮想円の直径ｒがＲ＞ｒ＞１／８Ｒの関係を満足する断面円弧状をした合成樹脂製の短冊状片から形成されていることに限定されるが、その理由は以下のとおりである。
すなわち、直径ｒが直径Ｒより大きいと、羽根体の曲面が平面に近くなり十分に揚力を受けることができない。また、短冊状片を、上記のように合成樹脂管を合成樹脂管の管軸を含む面に沿って分割することによって得るようにした場合、原材料となる合成樹脂管の内径も大きいものとなり、結果厚肉の管を使用することから不必要な厚みの部材となってしまったり、余りの端材が多く発生してしまい非効率である。
一方、直径ｒが１／８Ｒより小さいと、羽根体で十分に風を受けることができなくなり回転能力の低下を招くこととなる。 As described above, in the crossflow wind turbine of the present invention, the blade body is erected on the rotating plate with the outermost edge coinciding with the virtual circle having the diameter R on the rotating plate, and the inner arc surface is Although the diameter r of the containing virtual circle is limited to being formed from a strip-shaped piece made of a synthetic resin having a circular arc shape that satisfies the relationship of R>r> 1 / 8R, the reason is as follows. is there.
That is, if the diameter r is larger than the diameter R, the curved surface of the blade body is close to a flat surface and cannot receive sufficient lift. In addition, when the strip-like piece is obtained by dividing the synthetic resin tube along the surface including the tube axis of the synthetic resin tube as described above, the inner diameter of the synthetic resin tube as a raw material becomes large, As a result, a thick-walled tube is used, resulting in a member having an unnecessary thickness, and excessive end material is generated, which is inefficient.
On the other hand, if the diameter r is smaller than 1 / 8R, the blades cannot sufficiently receive the wind, resulting in a decrease in rotational ability.

上記羽根体の原材料となる合成樹脂管の材質としては、特に限定されないが、例えば、ポリエチレン、架橋ポリエチレン、ポリプロピレン、ポリブテン、ポリフェニレンスルフィド（ＰＰＳ）、ポリエチレンテレフタレート、ポリ塩化ビニル等が挙げられ、好ましくは、近年高騰する石油価格に伴って価格の上昇の少ない樹脂で、また溶剤等を利用した接着性の優れるポリ塩化ビニル系樹脂組成物を使用することが好ましく、ポリ塩化ビニル系樹脂組成物のなかでも、耐衝撃性を向上させるために、ゴム成分を含んだポリ塩化ビニル系樹脂組成物がより好ましい。   The material of the synthetic resin tube used as the raw material of the blade body is not particularly limited, and examples thereof include polyethylene, cross-linked polyethylene, polypropylene, polybutene, polyphenylene sulfide (PPS), polyethylene terephthalate, and polyvinyl chloride. However, it is preferable to use a polyvinyl chloride resin composition that is excellent in adhesiveness using a solvent, etc., with a resin that does not increase in price with the recent rising oil price, and among the polyvinyl chloride resin compositions However, in order to improve impact resistance, a polyvinyl chloride resin composition containing a rubber component is more preferable.

上記ゴム成分としては、特に限定されないが、例えば、塩素化ポリエチレン、エチレン・酢酸ビニル共重合体、アクリロニトリル・ブタジエン・スチレン（ＡＢＳ）ゴム、メチルメタクリレート・ブタジエン・スチレン（ＭＢＳ）ゴム、アクリル系ゴム等が挙げられる。
上記ゴム成分としての添加量は、少なすぎると耐衝撃性向上効果が得られず、多すぎると硬度や耐たわみ性が低下するので、ポリ塩化ビニル系樹脂１００重量部に対して、２〜２０重量部が好ましい。 The rubber component is not particularly limited. For example, chlorinated polyethylene, ethylene / vinyl acetate copolymer, acrylonitrile / butadiene / styrene (ABS) rubber, methyl methacrylate / butadiene / styrene (MBS) rubber, acrylic rubber, etc. Is mentioned.
If the addition amount as the rubber component is too small, the impact resistance improving effect cannot be obtained, and if it is too large, the hardness and the flex resistance decrease, so 2 to 20 with respect to 100 parts by weight of the polyvinyl chloride resin. Part by weight is preferred.

さらに、上記ポリ塩化ビニル系樹脂組成物には、有機錫系安定剤及び滑剤が添加されるのが好ましい。有機錫系安定剤としては、従来から使用されているものが使用され、例えば、ジブチル錫ラウレート等のラウレート系錫安定剤、ジブチル錫マレエート等のマレエート系錫安定剤、ジブチル錫メルカプチド、ジオクチル錫メルカプチド等のメルカプチド系錫安定剤、モノブチル錫サルファイド等のサルファイド系錫安定剤等が挙げられる。有機錫系安定剤の添加量は、少なすぎると安定化効果が得られず、必要量以上多くても安定化効果が殆ど変わらないので、ポリ塩化ビニル系樹脂１００重量部に対して、０．１〜５重量部が好ましい。   Further, an organotin stabilizer and a lubricant are preferably added to the polyvinyl chloride resin composition. As the organic tin stabilizer, those conventionally used are used, for example, laurate tin stabilizer such as dibutyltin laurate, maleate tin stabilizer such as dibutyltin maleate, dibutyltin mercaptide, dioctyltin mercaptide. And mercaptide-based tin stabilizers such as monobutyltin sulfide, and the like. If the addition amount of the organic tin stabilizer is too small, the stabilizing effect cannot be obtained, and if it is more than the required amount, the stabilizing effect is hardly changed. 1 to 5 parts by weight is preferred.

上記滑剤としては、樹脂の流動性を向上させると同時に、押出用金型表面との摩擦抵抗を減じて粘着を防止し、成形加工を容易にするものであって、例えば、ステアリン酸、パルミチン酸等の高級脂肪酸とその誘導体、金属石鹸類、カルバナワックス、キャンデリラワックス等の天然ワックス類、低重合度ポリエチレンのような合成ワックス類、パラフィンワックス類等の石油系ワックス類などが挙げられる。滑剤の添加量としては、少なすぎると樹脂の流動性向上効果が得られず、多すぎると必要物性が得られないので、ポリ塩化ビニル系樹脂１００重量部に対して、０．１〜２重量部が好ましい。   As the above-mentioned lubricant, the fluidity of the resin is improved, and at the same time, the friction resistance with the surface of the extrusion mold is reduced to prevent sticking, facilitating the molding process. For example, stearic acid, palmitic acid Higher fatty acids and derivatives thereof, metal soaps, natural waxes such as carbana wax and candelilla wax, synthetic waxes such as low-polymerization polyethylene, and petroleum waxes such as paraffin wax. If the amount of the lubricant is too small, the effect of improving the fluidity of the resin cannot be obtained. If the amount is too large, the necessary physical properties cannot be obtained. Therefore, 0.1 to 2 weights per 100 parts by weight of the polyvinyl chloride resin. Part is preferred.

また、上記合成樹脂管を構成する合成樹脂中には、光、熱、遷移金属イオンなどの作用によってラジカルが生成し、これらが自動酸化の連鎖サイクルに入ってしまい酸化反応が継続することによる合成樹脂の劣化を防ぐために、酸化防止剤を配合することが好ましい。
さらに、合成樹脂管を構成する合成樹脂中には、必要に応じて、成形性を向上させる目的で各種粘度調整剤・界面活性剤を配合したり、付加的成分、例えば、帯電防止剤、難燃剤、結露防止剤、及びこれらマスターバッチの付加的樹脂成分などを配合することが可能である。 Moreover, in the synthetic resin constituting the synthetic resin tube, radicals are generated by the action of light, heat, transition metal ions, etc., and these are entered into the auto-oxidation chain cycle, and the synthesis reaction is continued. In order to prevent deterioration of the resin, it is preferable to add an antioxidant.
Furthermore, in the synthetic resin constituting the synthetic resin tube, various viscosity modifiers / surfactants may be blended as necessary for the purpose of improving moldability, or additional components such as antistatic agents, It is possible to add a flame retardant, an anti-condensation agent, and an additional resin component of these master batches.

また、本発明のクロスフロー風車は、特に限定されないが、風車本体の周囲を囲むようにガイドベーンを備えていることが好ましい。
ガイドベーンの材質としては、特に限定されず、金属製でも合成樹脂製でも構わないが、軽量で薄く強度的に優れたもの、例えば塩ビ板やＦＲＰ製などの合成樹脂板、アルミニウム、ステンレス等が好ましい。 Moreover, the crossflow windmill of the present invention is not particularly limited, but it is preferable that a guide vane is provided so as to surround the periphery of the windmill body.
The material of the guide vane is not particularly limited, and may be made of metal or synthetic resin. However, it is lightweight, thin and excellent in strength, for example, a synthetic resin plate such as a PVC plate or FRP, aluminum, stainless steel, etc. preferable.

本発明にかかるクロスフロー風車は、以上のように、最外縁を前記回転板上の直径Ｒの仮想円に一致させた状態で回転板に立設されているとともに、内弧面を含む仮想円の直径ｒがＲ＞ｒ＞１／８Ｒの関係を満足する断面円弧状をした合成樹脂製の短冊状片から形成されているので、微風でも回転板が容易に回転するとともに安価で製造することができる。
したがって、小型で発電効率のよい、風力発電装置を提供することができ、環境にやさしい風力発電装置の普及につながる。
また、海岸沿岸地域等の塩害が発生する地域では羽根体が金属製であると、腐食・さびが発生してしまい風車の機能が果たせなくなるところ、羽根体が合成樹脂製であるので、腐食レスとなり、耐久性に富んだものとすることができる。 As described above, the crossflow wind turbine according to the present invention is erected on the rotating plate in a state where the outermost edge coincides with the virtual circle having the diameter R on the rotating plate, and includes a virtual circle including an inner arc surface. Is formed from a strip-shaped piece made of synthetic resin having a circular arc cross section satisfying the relationship of R>r> 1 / 8R, so that the rotating plate can be easily rotated and manufactured at low cost even with a slight wind. Can do.
Therefore, it is possible to provide a wind power generator that is small and has high power generation efficiency, leading to the spread of environmentally friendly wind power generators.
In areas where salt damage occurs, such as coastal coastal areas, if the blades are made of metal, corrosion and rust will occur and the windmill will not function. Thus, it can be made durable.

そして、上記短冊状片を、押出成形加工された合成樹脂管を、その管軸を含む面に沿って２〜２０に等分割することによって得るようにすれば、板から切り出したように断面形状が平面でなく、元の管形状を生かして、風を受ける側に湾曲した形状となるため、風による揚力を受けやすくなり風車として回転する上で効果的となる。
また、原材料として押出成形加工された合成樹脂管を用いることによって羽根体を軽量化することができて回転効率のよいものとすることができるとともに、小型のものであれば、羽根体の回転軸方向の寸法も短いものであるので、配管施工時に発生する合成樹脂管の端材を用いることができて、端材の有効利用を図ることができる。 If the strip-like piece is obtained by equally dividing the extruded synthetic resin tube into 2 to 20 along the surface including the tube axis, the cross-sectional shape is cut out from the plate. Is not a flat surface, but a shape that is curved toward the wind receiving side by utilizing the original tube shape, so that it is easy to receive lift from the wind and is effective in rotating as a windmill.
Further, by using an extruded synthetic resin tube as a raw material, it is possible to reduce the weight of the blade body and to improve the rotation efficiency. Since the direction dimension is also short, the end material of the synthetic resin pipe generated at the time of piping construction can be used, and the end material can be effectively used.

また、風車本体の周囲を囲むようにガイドベーンを備えている構成とすれば、より回転効率がよくなる。
そして、羽根体を、ゴム成分を含んだ耐衝撃性ポリ塩化ビニル樹脂組成物で形成しておくと、風とともに飛んできた異物が羽根体にあたっても破損することが少なく、耐久性に優れたものとすることができる。 Moreover, if it is set as the structure provided with the guide vane so that the circumference | surroundings of a windmill main body may be enclosed, rotational efficiency will become better.
And, if the blade body is made of an impact-resistant polyvinyl chloride resin composition containing a rubber component, the foreign matter flying with the wind is less likely to break on the blade body, and has excellent durability. It can be.

一方、本発明にかかる風力発電装置は、上記本発明のクロスフロー風車と、風車による回転駆動力を受けて発電する発電部とを搭載したので、安価で塩害にも強いものとすることができる。   On the other hand, since the wind turbine generator according to the present invention is equipped with the cross-flow wind turbine of the present invention and the power generation unit that generates power by receiving the rotational driving force of the wind turbine, it can be made inexpensive and resistant to salt damage. .

FIG.

以下に、本発明を、その実施の形態をあらわす図面を参照しつつ詳しく説明する。
図１は本発明の実施形態であるクロスフロー風車の１つの実施の形態をあらわしている。 Hereinafter, the present invention will be described in detail with reference to the drawings showing embodiments thereof.
FIG. 1 shows one embodiment of a crossflow wind turbine according to an embodiment of the present invention.

図１に示すように、このクロスフロー風車１は、風車本体２と、ガイドベーン部３とを備えている。
風車本体２は、図１〜図３に示すように、２枚の回転板２１と、６枚の羽根体２２とを備えている。 As shown in FIG. 1, the crossflow wind turbine 1 includes a wind turbine body 2 and a guide vane portion 3.
As shown in FIGS. 1 to 3, the windmill body 2 includes two rotating plates 21 and six blade bodies 22.

２枚の回転板２１は、それぞれポリ塩化ビニル樹脂組成物から形成され、その直径がＲの円盤状をしていて、一方の面に円盤の中心軸に沿うようにステンレス鋼製の回転軸２３が突設されていて、この回転軸２３が突設されていない面（以下、「対向面」）２１ａを対向させて配置されている。
また、２枚の回転板２１の対向面２１ａには、図４に示すように、それぞれ後述する羽根体２２の両端から突出する嵌合突部２２ａが嵌合する嵌合穴２４が穿設されている。 The two rotating plates 21 are each formed of a polyvinyl chloride resin composition, have a disk shape with a diameter of R, and have a rotating shaft 23 made of stainless steel on one surface along the central axis of the disk. Is provided so that a surface (hereinafter referred to as an “opposing surface”) 21a on which the rotating shaft 23 is not provided is opposed.
Further, as shown in FIG. 4, fitting holes 24 into which fitting protrusions 22 a protruding from both ends of a blade body 22 to be described later are fitted are formed in the opposing surfaces 21 a of the two rotating plates 21. ing.

羽根体２２は、以下のようにして形成されている。すなわち、図５に示すように、内径ｒが上記回転板２１の直径Ｒに対してＲ＞ｒ＞１／８Ｒの関係を満足するとともに、ゴム成分を含んだ耐衝撃性ポリ塩化ビニル樹脂組成物を押出成形して得た合成樹脂管Ｐを破線で示すようにその管軸を含む面に沿って６等分割して、図６に示すように、断面円弧状の短冊状片Ｐ１を得る。この短冊状片Ｐ１の長手方向の両端を図６に鎖線で示すように切削することによって得られる。したがって、長手方向の両端から嵌合突部２２ａが突出している。   The blade body 22 is formed as follows. That is, as shown in FIG. 5, the inner diameter r satisfies the relationship of R> r> 1 / 8R with respect to the diameter R of the rotating plate 21, and an impact resistant polyvinyl chloride resin composition containing a rubber component. The synthetic resin pipe P obtained by extrusion molding is divided into six equal parts along the plane including the pipe axis as shown by a broken line to obtain a strip-like piece P1 having an arcuate cross section as shown in FIG. It is obtained by cutting both ends in the longitudinal direction of the strip-shaped piece P1 as shown by a chain line in FIG. Therefore, the fitting protrusion 22a protrudes from both ends in the longitudinal direction.

そして、羽根体２２は、両側の嵌合突部２２ａを回転板２１の嵌合穴２４に嵌合させるとともに、接着固定することによって、等ピッチで中心軸に対して同じ角度となるとともに、最外縁が回転板２１の端縁に一致した状態で、すなわち、最外縁が直径Ｒの仮想円上に一致した状態で回転板２１間に固定されている。
また、羽根体２２は、内径ｒの合成樹脂管Ｐをその管軸を含む面に沿って６等分割して得た断面円弧状の短冊状片Ｐ１から形成されているので、羽根体２２の内弧面を含む仮想円の直径も同様にｒとなる。 The blade body 22 is fitted with the fitting protrusions 22a on both sides in the fitting holes 24 of the rotating plate 21 and bonded and fixed, so that the blade body 22 has the same angle with respect to the central axis at an equal pitch. The outer edges are fixed between the rotating plates 21 in a state where the outer edges coincide with the end edges of the rotating plates 21, that is, in a state where the outermost edge coincides with a virtual circle having a diameter R.
Further, since the blade body 22 is formed from a strip-shaped piece P1 having an arc-shaped cross section obtained by dividing the synthetic resin pipe P having an inner diameter r into six equal parts along the surface including the tube axis, The diameter of the virtual circle including the inner arc surface is also r.

ガイドベーン部３は、図１及び図３に示すように、ステンレス鋼製の２枚の固定板３１と、６枚のガイドベーン３２とを備えている。
２枚の固定板３１は、一方が風車本体２の上、他方が風車本体２の下に配置されて、回転板２１から突設された回転軸２３を、ベアリング３４を介して回転自在に支持している。
ガイドベーン３２は、羽根体２２外側に対向するように、かつ互いに間隔をもって２つの固定板３１間に立設されて、固定板３１に溶接固定されていて、羽根体２２方向へ空気流れを導くようになっている。 As shown in FIGS. 1 and 3, the guide vane unit 3 includes two fixing plates 31 made of stainless steel and six guide vanes 32.
One of the two fixed plates 31 is disposed above the windmill body 2 and the other is disposed below the windmill body 2, and rotatably supports the rotating shaft 23 protruding from the rotating plate 21 via a bearing 34. is doing.
The guide vane 32 is erected between the two fixed plates 31 so as to face the outer side of the blade body 22 and spaced from each other, and is welded and fixed to the fixed plate 31 to guide the air flow toward the blade body 22. It is like that.

そして、このクロスフロー風車１は、図７に示すように、矢印Ａ方向から風が流れている場合、その風がガイドベーン３２によって風車本体２に導かれ風車本体２の羽根体２２に当たり、羽根体２２が風力によって押され、風車本体２が回転軸２３を中心に回転する。しかも、このとき、羽根体２２の形状が断面円弧状をしているため、羽根体２２の両側部分に流れる空気流によって揚力が発生し、これが羽根体２２の回転力に加わることで実質的に回転トルクが増加することとなる。
また、風車本体２の回転板２１と、回転板２１との間には、羽根体２２しか設けられておらず、中央部には、空気の流れを阻害するものがない空間部Ｓが形成されているとともに、２つの回転板２１によって空間部Ｓの上下が閉鎖されているため、矢印で示す空気流に対して乱れを起こす要因がなく、よって、空間部Ｓにおけるクロスフローの発生、および羽根体２２における揚力の発生が効果的に行われることとなる。 As shown in FIG. 7, when the wind flows from the direction of arrow A, the crossflow wind turbine 1 is guided to the wind turbine body 2 by the guide vane 32 and hits the blade body 22 of the wind turbine body 2. The body 22 is pushed by the wind force, and the windmill body 2 rotates around the rotation shaft 23. In addition, at this time, since the shape of the blade body 22 has an arc shape in cross section, lift is generated by the air flow flowing on both side portions of the blade body 22, which is substantially added to the rotational force of the blade body 22. The rotational torque will increase.
Further, only the blade body 22 is provided between the rotating plate 21 and the rotating plate 21 of the windmill body 2, and a space portion S that does not obstruct the flow of air is formed in the center portion. In addition, since the upper and lower portions of the space portion S are closed by the two rotating plates 21, there is no factor causing disturbance to the air flow indicated by the arrows. Therefore, the occurrence of crossflow in the space portion S and the blades The generation of lift in the body 22 is effectively performed.

しかも、羽根体２２がゴム成分を含んだ耐衝撃性ポリ塩化ビニル系樹脂組成物で形成されているので、風車本体２が軽量化され微風でもよく回転するようになるとともに、耐衝撃性に優れ耐久性に富んだものとなる。
また、羽根体２２が耐衝撃性ポリ塩化ビニル系樹脂組成物を押出成形して得た合成樹脂管を、その管軸を含む面に沿って６等分割して短冊状片の端部を加工するだけで形成されるので、安価に大量生産することができる。したがって、風車全体の製造コストを下げることができる。 In addition, since the blade body 22 is formed of an impact-resistant polyvinyl chloride resin composition containing a rubber component, the windmill body 2 is reduced in weight so that it can rotate even in a breeze and has excellent impact resistance. It is rich in durability.
Further, a synthetic resin tube obtained by extruding the impact-resistant polyvinyl chloride resin composition with the blade body 22 is divided into 6 equal parts along the surface including the tube axis to process the end of the strip-shaped piece. Since it is formed only by doing, it can be mass-produced at low cost. Therefore, the manufacturing cost of the whole windmill can be reduced.

Since the voltage generated by the generator 5 is not stable due to a change in wind power, the controller 6 uses an inverter to convert and control the voltage according to the characteristics of the storage battery 7.

For example, in the above embodiment, the outer edge of the blade body is fixed between the rotating plates in a state where the outer edge of the blade body coincides with the periphery of the rotating plate, but the diameter R of the virtual circle connecting the outermost edges of the blade bodies is If R> r> 1 / 8R is satisfied, the outermost edge of each blade body may be provided so as to be inside from the periphery of the rotating plate (on the central axis side of the rotating plate).

さらに、羽根体は接着による固定だけでなく、融着やボルト固定でも構わない。
また、上記の実施の形態では、回転軸が上下の回転板のそれぞれに固定板方向に突出するように設けられていたが、強度を考慮すれば、１本の回転軸を上下の回転板を貫通するように設けてもよい。 In the above embodiment, the fitting protrusions are provided so as to protrude from both ends of the blade body. However, the strip-like pieces may be bonded and fixed to the opposing surfaces of the rotating plate as they are.
Furthermore, the blade body may be not only fixed by adhesion but also fused or bolted.
