Abstract

A vertical shaft windmill which is characterized in that four air collecting plates (4-1, 4-2, 4-3 and 4-4) are equidistantly disposed vertically and radially of the windmill (1) for driving a prime mover, and inclined at substantially 45 with respect to the radial direction of the windmill (1) opposite to the rotating direction thereof so that the angle of one air collecting plate (4-1) is generally 30 with respect to the direction of the most frequent winds experienced at the site throughout one year. The plates (4-1, 4-2, 4-3 and 4-4) collect a wide range of winds to accelerate the speed of the winds, and thus operate the windmill. This affords an improvement in the power production efficiency of a Savonius windmill which was regarded as disadvantageous over a Darius windmill in view of its production cost and in view of its heavy weight attributable to large-sized blades, although the Savonius mill does possess various advantages such as a large starting torque, high strength against strong winds are quiet operation. Thus, the windmill of this invention offers high strength against strong winds and a less pronounced decline in efficiency even if the direction of the wind is slightly altered. The air collecting plates prevent rotational loss attributed to the blades (1-2). Since the plates (4-2 and 4-4) collect the wind and strong winds pass between the plates (4-3 and 4-4) and between the plates (4-1 and 4-2), the air accumulated behind the blades (1-2) is blown out by the strong winds to thus prevent rotational loss of the windmill (1).

発明を実施するための最良の形態  BEST MODE FOR CARRYING OUT THE INVENTION
風力原動機装置に使用する風車には横軸型と縦軸型とがあり、 効率の点では It者の方 が勝っているが、 檮造及び設置の点では後者の方が有莉である。  There are two types of wind turbines used for wind power equipment, the horizontal axis type and the vertical axis type. The efficiency of the wind turbines is higher for the It users, but for the Yuzuki and the installation, the latter is more attractive.
縦 の中でも、 特にサボニュース型風車は設 ffが容易で、 且つ堅ろうである。  In particular, the Sabo News type wind turbine is easy to install and solid.
本発明は上記サボ二ユース型風草を甩ぃる原動機装置に適するもので、 動機を駆 13 する縦 型風車の周方に 枚の集風扳をつい立状に等間隔に配置し、 各集風扳を風車の 直径方向に対しその回転方向と反対側に略 度傾けて固定し、 設置場所における年間 を通じての平均的な風の方向に対して一集風板の角度が略 度を成すように設置する ことを特徴とする。  The present invention is suitable for a prime mover device using the above-mentioned savonou use type wind grass, and a plurality of wind collectors are arranged at regular intervals around a vertical wind turbine driving a motive force, and each of the wind turbines is arranged vertically. The wind turbine is fixed at an angle approximately opposite to the direction of rotation with respect to the diametric direction of the wind turbine so that the angle of the wind collecting plate makes an angle with the average wind direction throughout the year at the installation location It is characterized by being installed in
以下本発明装置の構造を図面について説明する。  Hereinafter, the structure of the device of the present invention will be described with reference to the drawings.
1は c2枚の羽根 1 - 1 · 1 -2を持ったサボニュース型 (縦軸抵抗型 ) 風草、 2 · 3は上 一 下一対の風草軸受ゎくにして、 原動機例えば発電機は、 篛状に形成した下部わく 3の中 に収容される。  1 is a sabo news type (longitudinal resistance type) windweed with two blades 1-1 · 1-2, 2 · 3 is a pair of upper and lower windmill bearings, and the prime mover such as a generator is 機It is accommodated in the lower frame 3 formed in a shape.
風車 1の周方に 枚の集風扳 4 -1 · 4 -2 · 4 -3 · 4 -4がつい立状に且つ等間隔に配置 されている。  Around the wind turbine 1, a number of wind collectors 扳 4 -1 · 4 -2 · 4 -3 · 4 -4 are arranged vertically and at equal intervals.
上記各集風扳 4 -1 · 4 -2 - 4 -3 · 4 - 4は、 風車 1の直径方向に ¾fし、 風車 1の回 方 向 A と反対側に略 度傾斜して上下のわく 2 · 3に固定されている  Each of the above-mentioned winds 4 -1 4 4 -2-4 -3 4 4-4 ¾f in the diametric direction of the wind turbine 1, and is approximately inclined to the direction A Fixed to 2 · 3
集風板の張り出し長さは、 少なくとも風車 1の半径程度は必要である。 The overhang length of the wind collecting plate should be at least about the radius of the wind turbine 1.

、 ΑΪΙ。 風力原動機装置を設置するような常時風が吹く場所の風向は、 年間を逼じて大体二方 向に分けられる。 , ΑΪΙ. The wind direction of a place where constant wind blows, such as the installation of a wind power unit, can be roughly divided into two directions in a narrow year.
そこで本発明装置は、 前記何れかの風車に合せてその平均的な風の方向 W に対して一 集風扳 4 -1が略 J 度の角度になるように向きを定めて設置される。  Therefore, the apparatus of the present invention is installed in such a manner that the direction of the collected wind -1 4-1 is approximately J degrees with respect to the average wind direction W in accordance with any of the wind turbines.
第 2図に示すように の方向から風が吹くと、 集風板の中特に集風扳 4 -1 · 4 -4によ つて広範囲の風が集められ、 自然風速よ 〜屮 Q % スピードアップされた状態 で風車 1に当り、 動力発生効率が上昇する。  As shown in Fig. 2, when the wind blows from the direction of, a wide area of wind is collected by the wind collecting plate, especially the wind collecting area 扳 4-1 4 4 -4, and the natural wind speed is increased by up to Q%. In this state, it hits the wind turbine 1 and the power generation efficiency increases.
そしてサボニュース型風車の場合、 '一方の羽根 1 "2が回転方向に し負の作用をして 若干の回転口スを生じさせるけれども、 本発明装置によれば集風扳によって前記羽根 1 ~2による回転ロスを防ぐことができる。  In the case of a Sabo news type wind turbine, 'one of the blades 1 "2 has a negative effect on the rotation direction to generate a small amount of rotation, but according to the device of the present invention, the blades 1 to 2 can prevent rotation loss.
即ち前記のように集風板 4 -1 · 4 -4間で集風作甩をし、 集風扳 4 - 3 · 4 -4間及び同 4 -1 · 4 -2間を強い風が逼 抜けるため、 羽根 1 ~2の背後にたまっている空気はその強風 に伴われて追出される。  That is, as described above, the wind collecting work is performed between the wind collecting plates 4-1 and 4-4, and the strong wind is tight between the wind collecting plates 4-3 and 4-4 and between the wind collecting plates 4-1 and 4-2. To escape, the air behind blades 1-2 is expelled by the strong wind.
従って風車 1に回転ロスを生じさせない。 Therefore, no rotation loss occurs in the wind turbine 1.
一集風板 4 -1に当る風の.向きが 度及び り度の場合は、 前記 J 度の場合に比べ て効率は / S〜ュ ％低下する。  When the direction of the wind that hits the collecting wind plate 4-1 is degrees and degrees, the efficiency is reduced by / S to u% compared to the case of the J degree.
又ヲ 度の角度 （ 集凰板 4 -1に対し直角 ） から風が吹いた場合、 その効率は一挙に 分の/程度に低下する。 When the wind blows from a certain angle (perpendicular to the phoenix board 4-1), the efficiency is reduced to a minute / minute at a stroke.
従って本発明装置を設置する場合、 風の吹く方向 W に ¾し、一集風板 4 -1の角度が略 3り度になるように設置するのが、 集風効果を挙げるのに最も効果がある。  Therefore, when installing the apparatus of the present invention, it is most effective to set the wind collecting plate 4-1 at an angle of about 3 degrees in the direction W of the wind and to obtain the wind collecting effect. There is.
又集風板の張り出し長さを風章 1の直径と略同じ長さにした場合、 前.記集風板 4 -1の風 に対する角度 J 度と相まって集風板無しの風車に比べて約 倍の効率があることが実 験の結果分った。 . In addition, when the overhang length of the wind collecting plate is set to be approximately the same as the diameter of the wind band 1, the angle of the wind collecting plate 4 -1 with respect to the wind J is about Experiments show that the efficiency is twice as high. .
しかし風向は多 Φ変化するので、 平均効 は J〜 倍とみるのが妥当である なお第 1図鎖線示に示すように、 必要により各集風板の上縁に、 集風板に当った風が 上方に反れるのを防ぐ整流板 5を設けることもある。 However, since the wind direction changes by many Φ, it is appropriate to consider the average effect to be J-fold As shown in the chain line in FIG. 1, a rectifying plate 5 may be provided on the upper edge of each wind collecting plate as needed to prevent the wind hitting the wind collecting plate from warping upward.

It is not good, but when directly driven such as a mature pump or a water pump, the efficiency can be raised by several to several tens of g, so that not only the field as an electric engineer but also the It seems that the way to use it as a power source will be endless.
又太陽電池と風力発電機が、 簡単に霄気ェネルギ一を取り出せるものとして将菜各分 野において競合するであろう。  Also, solar cells and wind power generators will compete in the field of shosai as a means to easily extract the energy of Xiaoki energy.
