Description

本発明は抗力型の風力発電機に関する物である。     The present invention relates to a drag type wind power generator.

従来の抗力型発電機は、羽根の裏表の形状で抵抗を変化させるものであり、回転効率は高くなく、また、プロペラ型発電機にも共通することであるが、羽根をハブの一点だけで支える構造なので、強度的に弱く、大型化すればするほど台風などの強風では回転させられないものであった。またそれを解決するための羽根を開閉するという発想はすでにあるがあまり実用化はされていない。   Conventional drag type generators change the resistance by the shape of the front and back of the blades, and the rotational efficiency is not high, and it is common to propeller type generators. Since it is a supporting structure, it is weak in strength and cannot be rotated by strong winds such as typhoons as the size increases. In addition, the idea of opening and closing the blades to solve this problem has already been put into practical use.

従来の抗力型発電機には効率の面で実用性が低かったり、強度に問題があるなどの解決すべき課題があった。     Conventional drag generators have problems to be solved such as low practicality in terms of efficiency and problems with strength.

上記目的を達成するために、本発明の抗力型開閉式発電機において請求項1に係るものは、羽根枠内の空間を開閉できる機能を備えた羽根を回転軸に設け、羽根同士をケーブルで連結したものである。また、回転軸の両端に環状レール上を移動可能な回転軸受け設け、その回転軸受けを環状レール上に備えたものであり、また、防風フェンスを環状レールの周囲に設けたものである。 In order to achieve the above object, the drag type open / close generator according to the present invention is characterized in that a blade having a function capable of opening and closing a space in a blade frame is provided on a rotating shaft, and the blades are connected by a cable. Concatenated. Further, a rotary bearing that can move on the annular rail is provided at both ends of the rotary shaft, the rotary bearing is provided on the annular rail, and a windbreak fence is provided around the annular rail.

本発明は、以上説明したように構成されており、以下に記載されるような効果を有する。 請求項1に係る仕組みを用いた場合、回転軸は環状レール上を移動可能な回転軸受けにより、風向きに合わせて環状レール上で自由に方向を変えることが出来る。また、回転軸に設けられた羽根枠内の空間を開閉できる機能を備えた羽根は、回転軸上側で羽根枠内の空間を閉じ、風から抗力を得られなくなった時点で羽根枠内の空間を開くことにより、羽根の上下の抗力差で回転軸を回転させる。また、羽根枠同士をケーブルで連結することによって、羽根の強度を高める。   The present invention is configured as described above and has the effects described below. When the mechanism according to claim 1 is used, the direction of the rotating shaft can be freely changed on the annular rail according to the wind direction by a rotating bearing movable on the annular rail. In addition, the blade with the function of opening and closing the space in the blade frame provided on the rotating shaft closes the space in the blade frame on the upper side of the rotating shaft, and when the drag cannot be obtained from the wind, the space in the blade frame By opening the, the rotating shaft is rotated by the drag difference between the upper and lower blades. Moreover, the intensity | strength of a blade | wing is raised by connecting blade frames with a cable.

環状レールの周囲に、回転軸の高さ付近まで防風フェンスで囲むことにより、戻り回転側の羽根に風を当てないようにすることで回転力を高めることができる。抗力型の発電機の欠点はプロペラ型に比べて効率が悪いことである。プロペラ型の発電機はすべての羽根が揚力によって回転力を得られるのに対して、抗力型は基本的に1枚のみしか回転力に寄与しない。その上、戻り回転側の羽根は風の速度に回転の速度が加わった抗力が反回転の力として作用する。開閉型の抗力発電機と言え、戻り回転の羽根の抵抗は重大な問題である。仮に開閉による面積の比率が10:1で、風と同じ速度で回転したとした場合、戻り回転側の羽根枠の風との相対速度は2倍となる。エネルギーは風速に3乗されるので、羽根にかかるエネルギーの比率が10:8となり、ほとんどの回転力が奪われてしまう。そこで本請求項では回転軸あたりまでの高さの防風フェンスをレールの周囲に設けることにより、回転軸に設けられた羽根が、戻り回転時に防風フェンスの中に入ることによって、風の抗力を受けないようにし回転力の低下を防ぐようにした。 By surrounding the annular rail with a windbreak fence up to the vicinity of the height of the rotary shaft, the rotational force can be increased by preventing the wind from being applied to the blades on the return rotation side. The drawback of the drag generator is that it is less efficient than the propeller type. In the propeller type generator, all blades can obtain rotational force by lift, whereas the drag type basically contributes to rotational force only by one. In addition, a drag force obtained by adding the rotation speed to the wind speed acts as a counter-rotation force on the return rotation blades. It can be said that it is an open / close type drag generator, and the resistance of the return rotation blades is a serious problem. If the ratio of the area by opening and closing is 10: 1 and it is rotated at the same speed as the wind, the relative speed with the wind of the vane frame on the return rotation side is doubled. Since the energy is raised to the third power of the wind speed, the ratio of energy applied to the blades is 10: 8, and most of the rotational force is lost. Therefore, in this claim, by providing a windbreak fence with a height up to the rotating shaft around the rail, the blades provided on the rotating shaft enter the windbreak fence during return rotation and receive wind drag. To prevent a decrease in rotational force.

本発明を実施するための形態を図1〜図3に基づいて説明する。環状レール(7)を設け、その上にレールに沿って移動可能な回転軸受け(3)を2つ設ける。2つの回転軸受け(3)は環状レール(7)の中心点を挟んで向かい合うように配置し、そこに回転軸(2)を取り付ける。回転軸(2)には4つの羽根枠(4)が90度おきに備えられ、それぞれ隣り合う羽根枠(4)と羽根連結ケーブル(6)によって連結される。また、羽根枠(4)は回転軸連結ケーブル(8)によって回転軸(2)とも連結される。羽根枠(4)には開閉幕(1)が備えられ、羽根が水平面より上にきたときに開閉幕(1)を開き羽根枠(4)内の空間を閉じるようにする。これによって、回転軸(2)上側の羽根に風が当たり、回転軸(2)下側の羽根は開閉幕(1)を閉じて面積が大幅に減り、上下の羽根の抗力差によって回転する。開閉幕(1)は抗力を増すために、帆船の帆みたいに膨らませるのもよい。また、回転軸受け(3)の片方に発電機を設置し、もう片方には環状レール(7)を移動するための駆動装置をのせるとよい。図1は斜視図であり、図2は上面図である。 The form for implementing this invention is demonstrated based on FIGS. 1-3 . An annular rail (7) is provided, and two rotary bearings (3) movable along the rail are provided thereon. The two rotary bearings (3) are arranged so as to face each other with the center point of the annular rail (7) interposed therebetween, and the rotary shaft (2) is attached thereto. The rotating shaft (2) is provided with four blade frames (4) every 90 degrees, and is connected to the adjacent blade frames (4) and the blade connecting cable (6). The blade frame (4) is also connected to the rotary shaft (2) by the rotary shaft connecting cable (8). The blade frame (4) is provided with an opening / closing curtain (1), and when the blade comes above the horizontal plane, the opening / closing curtain (1) is opened to close the space in the blade frame (4). As a result, wind hits the blades on the upper side of the rotating shaft (2), and the blades on the lower side of the rotating shaft (2) closes the opening / closing curtain (1) to greatly reduce the area and rotate due to the drag difference between the upper and lower blades. The opening / closing curtain (1) may be inflated like a sail of a sailing ship to increase drag. Moreover, it is good to install a generator in one side of a rotating bearing (3) and to mount the drive device for moving an annular rail (7) on the other side. 1 is a perspective view, and FIG. 2 is a top view.

3は図1の環状レール(7)の外周に防風フェンス()を設けたものである。防風フェンス()の高さは回転軸(2)のあたりまであり、回転軸(2)より下に位置する羽根枠(4)に風があたらないようにする。また、防風フェンス()は環状レール(7)の内側に位置しても働きは同じであるが、レール上の侵入を防ぐ意味においても環状レール(7)外周に防風フェンス()を設置するのが望ましい。 FIG. 3 shows a wind fence ( 5 ) provided on the outer periphery of the annular rail (7) of FIG. The height of the windbreak fence ( 5 ) extends to the rotation axis (2) so that the wind does not strike the blade frame (4) located below the rotation axis (2) . Also, although wind fence (5) is the same act be located inside the annular rail (7), wind fence annular rail (7) periphery is also in the sense of preventing the invasion of the rail (5) It is desirable to install.
