Description
本発明は、多段羽根縦軸風車に係り、特に１本の縦主軸に、羽根を多段に配設した多段羽根縦軸風車に関する。 The present invention relates to a multistage blade vertical axis wind turbine, and more particularly to a multistage blade vertical axis wind turbine in which blades are arranged in multiple stages on one longitudinal main shaft.
従来、風力発電機の風車は、横軸プロペラ式が使用され、風力回収率が３５％程度と云われる縦軸風車は、実用性がないものとして使用されていないのが現状である。
最近、小型の縦軸風車が研究されている。
Conventionally, a wind turbine of a wind power generator uses a horizontal axis propeller type, and a vertical axis wind turbine having a wind power recovery rate of about 35% is not used because it is not practical.
Recently, small vertical wind turbines have been studied.
縦軸風車は、例えば主軸の左右に羽根があるため、左方の羽根に風を受けて回転するとき、逆に右方の羽根は風の抵抗を受けるという難点がある。その結果、羽根の弦長（前後幅）を狭くして、背丈を高くすることが好ましいが、羽根の背丈を高くすると剛性を求められ、剛性を高くすると、重量が重くなり回転効率が悪化するという欠点が生じる。更に製造コストが高くなり、またメンテナンス作業性が悪くなる。
この発明は、羽根をより軽量化し、羽根の受風面積を広くすることの出来る、多段羽根縦軸風車を提供することを目的としている。
Since the vertical axis wind turbine has blades on the left and right of the main shaft, for example, when the left blade receives wind and rotates, the right blade receives a wind resistance. As a result, it is preferable to increase the height by reducing the chord length (front / rear width) of the blade, but increasing the height of the blade requires rigidity, and increasing the rigidity increases the weight and decreases the rotation efficiency. This causes a drawback. Further, the manufacturing cost is increased and the maintenance workability is deteriorated.
An object of the present invention is to provide a multistage blade longitudinal axis wind turbine that can further reduce the weight of the blade and increase the wind receiving area of the blade.

In addition, by making the struts as high as 30-50 m, it is possible to use high-speed high-speed wind. As the blades become smaller and lighter, the manufacturing cost burden is reduced, and since the blades are small and light, they are excellent in workability and easy to maintain.

本願発明の実施の形態例を、図面を参照して説明する。図１は本発明に係る多段羽根縦軸風車の要部正面図、図２は図１における多段羽根縦軸風車の要部平面図である。
図において、多段羽根縦軸風車(1)は、ケース体(1a)に、縦主軸(2)が垂直に、かつ回転自在に支持されている。
ケース体(1a)の中には、例えば図示しない発電機（ダイナモ）が、縦主軸(2)の回転力で発電することが出来るように配設されている。
Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front view of an essential part of a multistage blade vertical axis wind turbine according to the present invention, and FIG.
In the figure, a multistage blade vertical axis wind turbine (1) has a longitudinal main shaft (2) supported vertically and rotatably on a case body (1a).
In the case body (1a), for example, a generator (dynamo) (not shown) is disposed so as to be able to generate power with the rotational force of the longitudinal main shaft (2).
また縦主軸(2)から所定の半径位置に、複数の支柱(3)が定間隔で立設され、縦主軸(2)の上部、並びに中間の軸受(4)が、軸支持体(5)で支持されている。
図中の符号(6)は基盤であり、(7)は屋根である。該屋根(7)の上には、図示しない太陽光発電パネルを配設する事が出来る。
In addition, a plurality of support columns (3) are erected at regular intervals at a predetermined radial position from the vertical main shaft (2), and an upper portion of the vertical main shaft (2) and an intermediate bearing (4) are connected to the shaft support (5). It is supported by.
Reference numeral (6) in the figure is a base, and (7) is a roof. A solar power generation panel (not shown) can be disposed on the roof (7).
縦主軸(2)には、上下に複数（図では２）の回転体(8)が配設されている。回転体(8)は、縦主軸(2)に固定される軸部(8a)に、支持アーム(8b)が固定されている。上下の支持アーム(8b)の先端部は、上下でそれぞれ反対方向を向くように設定されている。 A plurality (2 in the figure) of rotating bodies (8) are arranged on the vertical main shaft (2) in the vertical direction. In the rotating body (8), a support arm (8b) is fixed to a shaft portion (8a) fixed to the vertical main shaft (2). The tip portions of the upper and lower support arms (8b) are set to face in opposite directions in the vertical direction.
各支持アーム(8b)の先端部には、縦長の揚力羽根(9)が、左側面を縦主軸(2)方向へ向けて、縦中間部を固定されている。羽根(9)の横断平面は、略魚形で、左側前縁部に大きな膨出部が形成されて、羽根(9)の上下部には、左側（縦主軸）方向へ傾斜した傾斜部(9a)が形成されている。 A vertically long lifting blade (9) is fixed to the tip of each support arm (8b) with its left intermediate surface facing in the direction of the longitudinal main axis (2). The transverse plane of the wing (9) is substantially fish-shaped, and a large bulge is formed on the left front edge, and on the upper and lower portions of the wing (9), an inclined portion (inclined on the left side ( vertical main axis)) ( 9a) is formed.
回転体(8)の支持アーム(8b)と羽根(9)の左側面との間には、羽根(9)の揺動を防止する為の羽根支持体(10)が、傾斜状に配設されている。この羽根支持体(10)は、ネジ止式にできるが、羽根(9)と支持アーム(8b)との結合部を、ＦＲＰ成形で一体にすることができる。 Between the support arm (8b) of the rotating body (8) and the left side surface of the blade (9), the blade support (10) for preventing the blade (9) from swinging is disposed in an inclined manner. Has been. The blade support (10) can be screwed, but the joint between the blade (9) and the support arm (8b) can be integrated by FRP molding.
図１において、上段と下段では風の向きや風速が違う。このことから、上段と下段の羽根(9)に当る風力が当然に異なってくる。図１．２において、南風（Ａ矢示の風）によって、下段のＡ羽根(9)が回転すると、縦主軸(2)が回転する。 In FIG. 1, the wind direction and wind speed are different between the upper and lower stages. From this, naturally the wind force which hits the upper and lower blades (9) is different. In FIG. 1.2, when the lower A blade (9) is rotated by the south wind (wind indicated by arrow A), the longitudinal main shaft (2) is rotated.
縦主軸(2)の回転力によって回転する、上段のＢ羽根(9)は、風の抵抗を受けるが、羽根(9)の左側面前縁部が膨出しているために、その部分を通過する風速が早くなり、負圧が生じることから揚力（回転推力）が生じて、自走回転をする。 The upper B blade (9), which is rotated by the rotational force of the longitudinal main shaft (2), is subjected to wind resistance, but passes through that portion because the left side front edge of the blade (9) bulges. Since the wind speed becomes faster and negative pressure is generated, lift (rotational thrust) is generated, and self-running rotation occurs.
そして上段のＢ羽根(9)が図１の左方に移動して、風による回転をするとき、下段のＡ羽根(9)は縦主軸(2)の右方へ回っても、風力で回転してきた力で回転し、かつ揚力（回転推力）による自走回転をする。 When the upper B blade (9) moves to the left in FIG. 1 and rotates by wind, the lower A blade (9) rotates by wind even if it rotates to the right of the longitudinal main shaft (2). Rotates with the force that has been generated, and performs self-running rotation by lift (rotational thrust).
このように、図１．２における同一水準段においては、羽根(9)は１枚なので、縦主軸(2)を挟んだ反対側に、風の抵抗を受ける羽根がないため、１枚の羽根(9)は風に押されて回転し、揚力による自走回転をプラスする。異なった他段の羽根(9)が、定期的に同じ作用を繰り返すので、効率のよい風力回収をすることができる。 Thus, in the same level stage in FIG. 1.2, since there is one blade (9), there is no blade that receives wind resistance on the opposite side across the longitudinal main shaft (2), so one blade (9) is rotated by being pushed by the wind, plus free-running rotation due to lift. Different blades (9) of different stages periodically repeat the same action, so that efficient wind recovery can be achieved.
この同一水準段において、縦主軸(2)を挟んだ羽根(9)の反対側軸部(3a)には、バランス体、アンバランス体あるいは別の羽根を配設する事ができる。
また上下の軸受(4)の間に、回転体(8)を複数配設すると、支柱(3)の高さを有効に利用することが出来る。
In the same level stage, a balance body, an unbalance body, or another blade can be disposed on the opposite shaft portion (3a) of the blade (9) sandwiching the longitudinal main shaft (2).
If a plurality of rotating bodies (8) are disposed between the upper and lower bearings (4), the height of the support column (3) can be used effectively.
図３は、第２実施例を示す、多段羽根縦軸風車の要部正面図である。前例と同じ部位には同じ符号を付して説明を省略する。
この第２実施例は、羽根(9)を３段に配設したものである。平面における羽根(9)の位置は、図４に示すように、回転トラック上で均等分割（１２０度毎）した位置に配設される。
FIG. 3: is a principal part front view of the multistage blade | wing vertical axis | shaft wind turbine which shows 2nd Example. The same parts as those in the previous example are denoted by the same reference numerals and description thereof is omitted.
In the second embodiment, the blades (9) are arranged in three stages. As shown in FIG. 4, the position of the blade (9) on the plane is arranged at a position equally divided (every 120 degrees) on the rotating track.
この第２実施例の多段羽根縦軸風車(1)においては、各段においては１枚羽根の特徴を有し、平面においては、３枚羽根のバランスを有している。
例えば、羽根(9)の背丈を６メートルにしようとすると、強度を強化して重量が重くなる。従って支持アーム(8b)の強度も強化しなければならない。更に縦主軸(2)の強度も強化する必要が出てくる。
In the multistage blade vertical axis wind turbine (1) of the second embodiment, each stage has the characteristics of one blade, and the plane has a balance of three blades.
For example, if the height of the blade (9) is set to 6 meters, the strength is increased and the weight is increased. Therefore, the strength of the support arm (8b) must be strengthened. Furthermore, the strength of the longitudinal main shaft (2) needs to be strengthened.
しかし、羽根(9)を３段に配設したことによって、羽根(9)の受風面積が同じならば、６ｍの羽根の３分の１の２メートルの背丈でよい（弦長が同じ時）ことになるので、剛性もそれに適合するものでよく、支持アーム(8b)も当然に軽量化することができる。更に縦主軸(2)も、上下の複数の軸受(4)で支持されるので、細い縦主軸(2)で十分になる。 However, if the wind receiving area of the blade (9) is the same by arranging the blades (9) in three stages, the height of one-third of the 6m blade can be 2 meters (when the string length is the same). Therefore, the rigidity may be adapted to that, and the support arm (8b) can also be reduced in weight. Furthermore, since the vertical main shaft (2) is also supported by a plurality of upper and lower bearings (4), a thin vertical main shaft (2) is sufficient.
図５は、第３実施例を示す、多段羽根縦軸風車の要部正面図である。前例と同じ部位には同じ符号を付して説明を省略する。
この第３実施例は、４段羽根に構成されている。上下における羽根(9)の平面位相は、９０度ごとに違差されている。
FIG. 5: is a principal part front view of the multistage blade | wing vertical axis | shaft wind turbine which shows 3rd Example. The same parts as those in the previous example are denoted by the same reference numerals and description thereof is omitted.
The third embodiment is configured with four-stage blades. The plane phase of the upper and lower blades (9) is different every 90 degrees.
気圧は地上から高くなる毎に変化する。従って、風圧、風速も地上からの高位差によって変化する。一般には上空の方が風速は早い。このことから、地上２ｍの位置の羽根と８ｍの位置の羽根とでは受ける風速に差が生じる。 The atmospheric pressure changes each time it rises from the ground. Therefore, the wind pressure and the wind speed also change due to a high level difference from the ground. Generally, the wind speed is higher in the sky. For this reason, a difference occurs in the wind speed received between the blade at a position 2 m above the ground and the blade at a position 8 m.
従って、下段と最上段の羽根の受ける風速の差が大きい場合は、初期においては、上段の風速による回転主導が行われる。この場合下段の羽根の抵抗が負担になる時は、縦主軸(2)に捩じれが生じる虞がある。 Therefore, when the difference between the wind speeds received by the lower and uppermost blades is large, the rotation is driven by the upper wind speed in the initial stage. In this case, when the resistance of the lower blade becomes a burden, the vertical main shaft (2) may be twisted.
その場合には、下段から上段にかけて配設される羽根(9)の面積を、順次一定比率で狭くする事ができる。又は回転体(8)の支持アーム(8b)の長さを、上部では下より短くすることにより調節することができる。羽根支持体(10)は図示のように水平にすることができる。 In that case, the area of the blades (9) arranged from the lower stage to the upper stage can be successively reduced at a constant ratio. Alternatively, the length of the support arm (8b) of the rotating body (8) can be adjusted by making it shorter at the upper part than at the lower part. The blade support (10) can be horizontal as shown.
図６は、第４実施例を示す、多段羽根縦軸風車の要部正面図である。前例と同じ部位には同じ符号を付して説明を省略する。
この第４実施例では、支柱(3)を高くして、羽根(9)を支柱(3)の高い位置にのみ配設したものである。この第４実施例において、例えば支柱(3)の高さが１０ｍとすると、縦主軸(2)も１０ｍとして、地上にケース体(1a)を配設して発電器を中に配設すると、メンテナンスが容易となる。
FIG. 6 is a front view of an essential part of a multistage blade vertical axis wind turbine showing a fourth embodiment. The same parts as those in the previous example are denoted by the same reference numerals and description thereof is omitted.
In the fourth embodiment, the strut (3) is raised and the blade (9) is disposed only at a high position of the strut (3). In this fourth embodiment, for example, if the height of the support column (3) is 10 m, the longitudinal main shaft (2) is also 10 m, the case body (1a) is arranged on the ground, and the generator is arranged inside, Maintenance becomes easy.
しかし、縦主軸(2)が長くなると、重量負荷、捩じれ等の問題が生じる虞があるので、図示するように、例えば中間に変速器(1b)を配して、縦主軸(2)を上下に複数とすることができる。これによって、羽根(9)支持部分の縦主軸(2)の直径を、太くすることが抑制される。 この構成においては、支柱(3)を３０ｍ、５０ｍ等にするような、大がかりな風力発電に利用することができる。 However, if the longitudinal main shaft (2) becomes longer, problems such as weight load and twisting may occur.Therefore, as shown in the figure, for example, a transmission (1b) is arranged in the middle and the vertical main shaft (2) is moved up and down. There can be more than one. This suppresses the diameter of the longitudinal main shaft (2) of the supporting portion of the blade (9) from being increased. In this configuration, the column (3) can be used for large-scale wind power generation such as 30 m, 50 m, and the like.
また羽根(9)について、支柱(3)の高位置において、上段と下段においては異なった風速を受けるので、受風面積を下段より上段の羽根を小さくする以外の手段としては、回転体(8)の支持アーム(8b)の長さを下段のよりも上段の方を短くするすることにより、縦主軸(2)に対するトルクを調整することができる。この支持アーム(8b)は長いほど梃子の原理で軸トルクを大きくすることができる。 Also, the blade (9) receives different wind speeds at the upper and lower stages at the high position of the support post (3) .Therefore, as a means other than reducing the upper blade from the lower stage, the rotating body (8 ), The torque on the longitudinal main shaft (2) can be adjusted by making the upper arm shorter than the lower arm. The longer the support arm (8b), the greater the shaft torque can be based on the lever principle.
図７は、第４実施例を示す多段羽根縦軸風車の、支柱と軸受のユニット(11)を示す要部正面図、図８はその平面図である。
このユニット(11)は、支柱(3)を一定の長さとし、この支柱(3)複数と軸支持体(5)と軸受(4)とをセットとしているものである。支柱(3)は図示するように、上端部に嵌合突体(3a)を形成し、下端部に、嵌合突体(3a)が嵌合される嵌合凹部(3b)が形成されている。

Thus, the tip fixing portion (5b) of the shaft support (5) is used for fixing the shaft support (5) to the support column (3) and fixing and reinforcing the connecting portion of the upper and lower support columns (3). .
