Description

発電電力数百ワットから数キロワットの小型風力発電装置等に使用する風車は多くの種類があるが、回転速度は比較的遅いが回転トルクが比較的大きいものにサボニウス型風車がある。本考案は、サボニウス型風車の風車翼に布またはシートを利用することによって安価かつ設置現場で簡単に組み立て可能なものである。There are many types of windmills used in small wind power generators with a power generation of several hundred watts to several kilowatts, but there are Savonius type windmills that have a relatively slow rotational speed but a relatively large rotational torque. The present invention is inexpensive and can be easily assembled at an installation site by using cloth or a sheet for a wind turbine blade of a Savonius type wind turbine.

風車翼に帆布を使用する技術は古くからスペイン、オランダ、地中海、エーゲ海諸国に見られる。その多くは、プロペラ形水平翼型風車であり、垂直翼型風車であるサボニウス型風車の翼に布を使用した事例はない。
古来、帆船の時代には風が動力の主体であり、風を受ける帆と材料である帆布の製造が盛んであった。このため、帆布を風車翼に利用しようとする考えはごく自然であったと思われる。
近年では、船の動力に風を使うことは殆ど消滅しつつあり、レジャー・スポーツ用ヨットなどにのみ帆が使用されているが、単なる麻などの自然繊維のみではなく人工布である合成樹脂繊維などを使用した強固な帆布が採用されている。
近年、地球温暖化の原因とされる炭酸ガスの放散を抑制するため化石燃料の燃焼を抑制するため、太陽、風、水、地熱などのエネルギー利用が活発化してきた。
特に、風力発電は大型のプロペラ型水平式風車が主流になっているが、これは、１基で数百キロワットの瞬間電力を発生することができるプロペラ半径６０メートル程度の大きなものであり、騒音問題、雷などによる破損、相当な風速を必要とする立地条件などのデメリットも大きく普及が進まないのが現状である。
一方、電気自動車の普及の見通しが出てきた今日、一般家庭でもローカルに自然発電を行い、夜間に充電しておくなど、買電も含めて発電のローカル化も今後広がる可能性がある。
住宅地において騒音が少なく、比較的コンパクト形状にして低風速で高いトルクが得られるサボニウス型風車はローカル発電には最適なものと考えられる。The technology of using canvas for windmill wings has long been found in Spain, the Netherlands, the Mediterranean, and the Aegean countries. Most of them are propeller-type horizontal wing wind turbines, and there are no examples of using cloth on the wings of a Savonius-type wind turbine, which is a vertical wing wind turbine.
Since ancient times, wind was the main driving force in the era of sailing ships, and the production of sails that received the wind and canvas, a material, was thriving. For this reason, it seems that the idea of using canvas for wind turbine blades was very natural.
In recent years, the use of wind for ship power is almost disappearing, and sails are used only for leisure and sports yachts, but not only natural fibers such as hemp but synthetic resin fibers that are artificial fabrics A strong canvas is used.
In recent years, the use of energy such as the sun, wind, water, and geothermal heat has been activated in order to suppress the combustion of fossil fuels in order to suppress the emission of carbon dioxide, which is a cause of global warming.
In particular, large-scale propeller-type horizontal wind turbines are mainly used for wind power generation, but this is a large propeller with a radius of about 60 meters that can generate instantaneous power of several hundred kilowatts with a single unit. The current situation is that the disadvantages such as problems, damage caused by lightning, location conditions that require considerable wind speed, etc. are not widespread.
On the other hand, with the prospect of the popularization of electric vehicles, there is a possibility that the localization of power generation, including power purchases, will spread in the future, such as natural power generation even in ordinary homes and charging at night.
Savonius type windmills with low noise, low wind speed and high torque in residential areas are considered optimal for local power generation.

サボニウス型風車の翼は蒲鉾が二つ向き合っているような形状である。
この蒲鉾状の円弧を持った風車翼を製造するには、アルミニウムのような軽量な金属か、ＦＲＰ樹脂などを使用するが、毎秒風速５メートル程度の風で平均１ＫＷ程度の電力を発生するためには、経験則から計算して片側風車翼約８０ｍ２位の受風断面積を有する風車翼を製作する必要がある。
この寸法の風車翼を金属または合成樹脂で製作すると、高価であるばかりでなく、重く、大きいために運搬などの取り扱いも容易ではない。
また、風車翼の寸法を変更するたびに莫大な設計・製造時間を要する。The wings of the Savonius type windmill are shaped like two wings facing each other.
To manufacture a wind turbine blade having a saddle-shaped arc, a light metal such as aluminum or FRP resin is used, but it generates an average power of about 1 kW with a wind speed of about 5 meters per second. Therefore, it is necessary to manufacture a wind turbine blade having a wind receiving cross-sectional area of about 80 m 2 on one side calculated from an empirical rule.
When a wind turbine blade of this size is made of metal or synthetic resin, it is not only expensive, but also heavy and large, and handling such as transportation is not easy.
In addition, an enormous design and manufacturing time is required every time the dimensions of the wind turbine blade are changed.

風車翼を、完全な円弧・円筒形ではなく多角・角錐形近似することによって、折りたたんで運搬できる構造とし、かつ、トラス構造の骨組みと布またはシートを組み合わせることによって強靭な構造とした。The wind turbine blades were folded and transported by approximating polygons and pyramids instead of complete arcs and cylinders, and were made tough by combining a truss structure frame and cloth or sheet.

製造容易で、設置現場において誰でも簡単に組み立てることが可能であり、かつ、安価に製作できるようにした。It is easy to manufacture, can be easily assembled by anyone at the installation site, and can be manufactured at low cost.

既存の典型的なサボニウス型風車を示した図である。回転軸（３）と一体結合した上下の風車翼固定部材（４）に風車翼（１）（２）を固定する。紙面方向に風が吹くと、風車翼（２）が風車翼（１）より抗力が大きくなり逆時計回りに回転する。図示のごとく二つの風車は相互に重複部分をもつことによって、風車翼（２）の受風の一部を風車翼（１）の方へ廻すことによって、より、回転効率を良好ならしめている。It is the figure which showed the existing typical Savonius type | mold windmill. The wind turbine blades (1) and (2) are fixed to the upper and lower wind turbine blade fixing members (4) integrally coupled with the rotating shaft (3). When wind blows in the direction of the paper, the wind turbine blade (2) has a greater drag than the wind turbine blade (1) and rotates counterclockwise. As shown in the figure, the two wind turbines have overlapping portions with each other, and by rotating a part of the wind received by the wind turbine blade (2) toward the wind turbine blade (1), the rotational efficiency is further improved. 本考案による片側の風車翼を説明した図面である。風車翼中心柱（６）と上下の斜め支持体（７）と上下の水平支持体（８）および縦支持体（９）とでトラス構造を構成するように、結節体（１０）、斜め滑節体（１１）、水平滑節体（１２）を造る。斜め支持体と水平支持体との角度は３０°程度とする。この目的は、強靭なトラス構造を形成するためと、雨、雪が上部に溜まらないようにするためである。すなわち、結節体（１０）は水平支持体（８）に固定され、斜め支持体（８）および縦支持体（９）を固定する機能をもつ。斜め支持体（７）のもう一方の端は風車翼中心柱（６）に固定したロープにフックによって固定される。全角度で自在に動くことができる。水平支持体のもう一方の端は水平滑節体（１２）に固定されるが、水平方向に１８０°の角度の動きが可能なように水平滑節体（１２）のヒンジに固定される。上下の斜め支持体（７）と縦支持体（９）は必要な強度のロープでもよいが、水平支持体は鋼体すなわち張力、伸縮力、せん断力、ねじり力に耐えるパイプ状、丸棒状の形状をした金属、木、竹などを加工したものである。以上説明した一対のトラス構造の骨組みを多角・角錐によって１８０°の蒲鉾形円弧を近似するため複数製作する。すなわち、図面では７対装備したものを示している。布またはシートを図のように骨組みに沿うように縫合製作して、縫い目を中心として裏側に縦支持体、斜め支持体を抱き込むように細長い布またはシートを縫合する。最左の縦支持体と最右の縦支持体とを最大広げると１８０°となるようにする。骨組みに装着する前に、布またはシートと斜め支持体、縦支持体を一体化しておくと設置現場での組み立てが容易となる。布またはシートの骨組みへの実装が終了した後、骨組みの最左と最右の上下水平支持体のそれぞれを１８０°の角度に広げて図１で示した風車翼固定部材に固定すれば、片側の風車翼が完成する。もう一方の風車翼も同様に製造して同様に固定すれば完成する。1 is a diagram illustrating a wind turbine blade on one side according to the present invention. The wind turbine blade center column (6), the upper and lower diagonal supports (7), the upper and lower horizontal supports (8), and the vertical supports (9) form a truss structure, A nodule (11) and a water smooth nodule (12) are made. The angle between the diagonal support and the horizontal support is about 30 °. The purpose is to form a strong truss structure and to prevent rain and snow from accumulating on the top. That is, the nodule (10) is fixed to the horizontal support (8) and has a function of fixing the oblique support (8) and the vertical support (9). The other end of the oblique support (7) is fixed by a hook to a rope fixed to the wind turbine blade center column (6). Can move freely at all angles. The other end of the horizontal support is fixed to the water smooth node (12), but is fixed to the hinge of the water smooth node (12) so that it can move at an angle of 180 ° in the horizontal direction. The upper and lower diagonal supports (7) and vertical supports (9) may be ropes of the required strength, but the horizontal supports are steel bodies, ie pipes, round bars that can withstand tension, stretching, shearing and torsional forces. Processed metal, wood, bamboo, etc. A plurality of frames of the pair of truss structures described above are manufactured in order to approximate a 180 ° saddle-shaped arc by polygons and pyramids. That is, in the drawing, seven pairs are provided. As shown in the figure, the cloth or sheet is sutured along the framework, and the elongated cloth or sheet is sewn so as to embrace the vertical support and the diagonal support on the back side around the seam. When the leftmost vertical support and the rightmost vertical support are widened to the maximum, the angle is set to 180 °. If the cloth or sheet is integrated with the diagonal support and the vertical support before being attached to the framework, the assembly at the installation site becomes easy. After the mounting of the fabric or sheet on the frame is completed, each of the left and right upper and lower horizontal supports on the frame is spread at an angle of 180 ° and fixed to the wind turbine blade fixing member shown in FIG. The windmill wing is completed. The other wind turbine blade is manufactured in the same manner and fixed in the same manner. 結節体（１０）は様々な形態が考えられるので、一例として考案したものを示す。斜め支持体と縦支持体とがロープである場合は上下の斜め滑節体までは一体連続したロープの方が手間を省ける。そのため、ロープ止めを外してロープを引き込み、ロープ止めをロープに引っ掛けて装着するように考案した。Since various forms of the nodule (10) are possible, what is devised as an example is shown. When the diagonal support and the vertical support are ropes, the rope that is integrally continuous up to the upper and lower diagonal joints can save time. Therefore, it was devised to remove the rope stopper, pull the rope, and hook the rope stopper on the rope.
