Description

本発明は、風力を効率よく利用できる垂直軸風車に関するものである。   The present invention relates to a vertical axis wind turbine that can efficiently use wind power.

従来の風車のうち、プロペラ型は、プロペラにねじり加工を要するなど高度な技術を要し、プロペラの半径以上の高さの塔を必要とし、又、プロペラを常に風の向きに従って移動回転させなければならない問題があった。   Among the conventional wind turbines, the propeller type requires advanced technology such as the propeller needs to be twisted, requires a tower whose height is higher than the radius of the propeller, and the propeller must always be moved and rotated according to the direction of the wind. There was a problem that had to be done.

又、従来の垂直軸風車は、回転力を生まない半分に対する逆風を消すことができないことが難点であった。   Further, the conventional vertical axis wind turbine has a difficulty in being able to extinguish the counter wind against half that does not generate rotational force.

この改善策として、風の整流板を取り付ける方法がある。しかしながら、この方法では、風の向きに合わせて絶えず整流板を動かさなければならず、構造が複雑となる。
日刊工業新聞 平成１８年１０月３０日版 As an improvement measure, there is a method of attaching a wind current plate. However, in this method, the current plate must be constantly moved according to the direction of the wind, and the structure becomes complicated.
Nikkan Kogyo Shimbun October 30, 2006 edition

解決しようとする問題点は、垂直軸風車において、回転力を生まない半分に対する逆風の力を消す点にある。   The problem to be solved is that in the vertical axis wind turbine, the force of the counter wind against the half that does not generate the rotational force is erased.

本発明は、逆風に対する風受板を、風の力を利用して基盤上に倒し、風の抵抗をなくすことを特徴とする。   The present invention is characterized in that the wind-receiving plate against the reverse wind is brought down on the base using the force of the wind to eliminate wind resistance.

回転する基盤上に、棒（連結棒）を、回転軸受を通して、基盤の中心を通る直線上に数本取付ける。   Several rods (connection rods) are mounted on a rotating base through a rotary bearing on a straight line passing through the center of the base.

その連結棒に基盤の中心点に対して左右対称となる風受板を、互いに９０度となるように捩った状態で取り付ける。   Wind guide plates that are symmetric with respect to the center point of the base are attached to the connecting rods while being twisted so as to be 90 degrees to each other.

同様な、風受板を取り付けた連結棒を、数本基盤の中心で交差させて取り付ける。   A similar connecting rod to which wind-receiving plates are attached is attached by crossing at the center of several bases.

本発明は、風車の回転を止めようとする力を極力ゼロに近付けることによって、風力を効率よく利用するという利点がある。   The present invention has an advantage of efficiently using wind power by bringing the force to stop the rotation of the windmill as close to zero as possible.

風車において、動力として利用される風力は、プロペラ・風受板に当る風によるものであるので、風向に対するプロペラ・風受板の面積に比例する。
これを、プロペラ式風車に当てはめた場合、正面から見たプロペラの総面積である。
一方、垂直軸風車の場合、正面から見た風受板の総面積は、原則として風車全体の右又は左半分となる。 In the wind turbine, the wind force used as power is due to the wind hitting the propeller / wind receiving plate, and is proportional to the area of the propeller / wind receiving plate with respect to the wind direction.
When this is applied to a propeller-type wind turbine, it is the total area of the propeller viewed from the front.
On the other hand, in the case of a vertical axis windmill, the total area of the wind receiving plate viewed from the front is in principle the right or left half of the entire windmill.

ところで、プロペラ式風車の場合、風向に正対するようにプロペラの向きを常に回転させなければならないため、プロペラ一枚分の長さを半径とする円形の設置場所を必要とする。   By the way, in the case of a propeller type windmill, since the direction of the propeller must always be rotated so as to face the wind direction, a circular installation place having a radius corresponding to the length of one propeller is required.

仮に、プロペラ式風車と同じ設置場所面積を占有する垂直軸風車を設置した場合、正面から見た風受板の総面積は、設置場所の半径×高さとなるが、高さは任意に設定できるため、広大となる。   If a vertical axis wind turbine that occupies the same installation location area as a propeller type wind turbine is installed, the total area of the wind receiving plate seen from the front is the radius x height of the installation location, but the height can be arbitrarily set Therefore, it becomes vast.

したがって、本発明のように風車の回転を止めようとする力を極力ゼロに近付けることが可能となれば莫大な風力を利用することができることとなる。   Therefore, if the force for stopping the rotation of the windmill can be made as close to zero as possible as in the present invention, a huge amount of wind power can be used.

回転する基盤上に、棒（連結棒）を、回転軸受を通して、基盤の中心を通る直線上に数本取付ける。   Several rods (connection rods) are mounted on a rotating base through a rotary bearing on a straight line passing through the center of the base.

その連結棒に基盤の中心点に対して左右対称となる風受板を、互いに９０度となるように捩った状態で取り付ける。   Wind guide plates that are symmetric with respect to the center point of the base are attached to the connecting rods while being twisted so as to be 90 degrees to each other.

同様の風受板を取り付けた連結棒を、数本、中心付近を上方又は下方に適宜曲げ、互いに接触しないように迂回、交差させて取り付ける。   Several connecting rods to which the same wind receiving plate is attached are bent in the vicinity of the center upward or downward as appropriate, and are detoured and crossed so as not to contact each other.

基盤については、腕木を用いる方法、正多角形の板等が考えられるが、円盤状が、風の抵抗も少なく好ましい。   As for the base, a method using a brace, a regular polygonal plate, and the like are conceivable, but a disk shape is preferable because of less wind resistance.

連結棒に代えて風受板を連結する方法は、他に、歯車、紐（ワイヤー）、カム等が考えられるが、簡単に且つ確実に連結するためには、棒を用いる方法が最良である。   Other methods for connecting the wind receiving plate instead of the connecting rod include gears, strings (wires), cams, etc., but in order to connect easily and reliably, the method using the rod is the best. .

基盤の中心付近上方の風受板間の空間は、円筒を用いてカバーしたほうが風力のロスが少なくなり、より好ましい。   It is more preferable that the space between the wind receiving plates near the center of the base is covered with a cylinder to reduce wind power loss.

本発明の垂直軸風車は、風受板が倒れた状態の時、隣接する風受板に接触しないようにしなければならず、風受板一枚毎の高さは制限を受けるが、風車自体を上下に複数重ねることによって、この欠点は克服可能である。   The vertical axis windmill according to the present invention must prevent contact with the adjacent wind receiving plate when the wind receiving plate is in a collapsed state, and the height of each wind receiving plate is limited. This disadvantage can be overcome by stacking a plurality of layers vertically.

図２は、この発明装置の風受板を取り付けた連結棒を、判り易くするため１本だけ抜き出し、連結棒に平行な方向から見た図であり、左方向より風を受けるものとする。   FIG. 2 is a view of the connecting rod with the wind receiving plate of the device according to the present invention, in which only one connecting rod is extracted for easy understanding, and viewed from a direction parallel to the connecting rod, and receives wind from the left direction.

１ａ−２の風受板は、風の抵抗を受け、右に向かって倒れ水平となる。   The wind receiving plate 1a-2 receives wind resistance and falls to the right and becomes horizontal.

水平となった１ａ−２の風受板は、風を素通りさせる。   The horizontal wind receiving plate 1a-2 allows the wind to pass through.

１ａ−２の風受板と２の連結棒を通じて連結された１ａ−１の風受板は、１ａ−２の風受板が倒れることにより、又、途中より自ら風を受けることにより、起き上がって垂直となる。   The windshield plate of 1a-1 connected through the windshield plate of 1a-2 and the connecting rod of 2 awakes up when the windshield plate of 1a-2 falls or receives wind from the middle. It becomes vertical.

１ａ−１の風受板は、風の抵抗を受け止める。   The wind receiving plate 1a-1 receives wind resistance.

１ａ−１の受け止めた風の抵抗は、２の連結棒、３の回転軸受を通じて４の基盤に伝わり、基盤を回転させる。   The wind resistance received by 1a-1 is transmitted to the base 4 through the two connecting rods 3 and the rotary bearing 3, and rotates the base.

図３は、本発明の垂直軸風車全体の見取り図であり、左下方より風を受けるものとする。   FIG. 3 is a sketch of the entire vertical axis wind turbine of the present invention, and receives wind from the lower left.

１b−２及び１c−２は、１ａ−２と同様に風の抵抗を受けて倒れ、水平となり、風を素通りさせる。   Like 1a-2, 1b-2 and 1c-2 fall by receiving wind resistance, become horizontal, and allow the wind to pass through.

１b−１及び１c−１は、１ａ−１と同様に垂直となって風の抵抗を受け止め、２の連結棒、３の回転軸受を通じて４の基盤に伝わり、基盤を回転させる。   1b-1 and 1c-1 are perpendicular to 1a-1 and receive wind resistance, are transmitted to the base 4 through the two connecting rods 3 and the rotary bearing 3, and rotate the base.

以上により効率的に風力エネルギーが回転運動エネルギーに変換される。   Thus, wind energy is efficiently converted into rotational kinetic energy.

この装置の回転エネルギーは、基盤に連結された５の軸を通して、動力として発電等に利用可能となる。   The rotational energy of this device can be used for power generation or the like as power through five shafts connected to the base.

この発明は、風力発電をはじめとするさまざまな風力の動力利用に適用できる。   The present invention can be applied to the use of various wind powers including wind power generation.
