Abstract

<P>PROBLEM TO BE SOLVED: To provide a vertical axis windmill and a blade which start rotating in a breeze and rotate at high speed. <P>SOLUTION: The blade is developed so that the wind received by a strip-like plate 1 is received by a V-shaped blade distal end member 2 and is flowed toward the shaft. Consideration is given to the number of blades and their positions so that each blade is subjected to the wind to cause impulsive force and thus high speed rotation. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

本発明は、ミニ風力発電用垂直軸直線翼風車及びブレードに関する。The present invention relates to a vertical axis straight blade wind turbine and a blade for mini wind power generation.

従来、垂直軸風力発電の風車には、ダリウス型、ジャイロミル型、クロスフロー型等色々有るが、微風では回転しない、回転が遅いなどである。Conventionally, there are various types of wind turbines for vertical axis wind power generation, such as Darrieus type, gyromill type, and cross flow type, but they do not rotate with a light wind and rotate slowly.

微風で回転を始め、高速で回転する垂直軸直線翼ブレード、配置等を開発し効率良い発電用風車を提供することを目的とする。The purpose is to provide a wind turbine for efficient power generation by developing a vertical axis straight blade blade, arrangement, etc. that starts rotating with a breeze and rotates at high speed.

短冊状のプレートに当たる回転方向への風をＶ字型ブレード先端部材で受け、受けた風を軸方向へ流し抗力の効率化を計る。又、Ｖ字型ブレード先端部材は空気抵抗を考え丸みをもったＶ字型にし、プレート側を半円径に窪ませる。短冊状のプレートの幅、厚みそしてＶ字型ブレード先端部材の幅、厚みは空気抵抗、抗力等を考え決める。ブレードの本数、配置等が回転に与える影響が大きいのでブレードに風が当たるように風の通りを考え決める。ブレードを支える回転翼は空気抵抗を考え流線形にする。又、ガイドベーン、ダブル遠心クラッチ等を使用する。ダブル遠心クラッチは微風で回転する風車を上部に、微風では回転しない風車を下部に接続する。そのことにより発電機負荷のかかった下部の風車の初動回転を助ける。The wind in the direction of rotation hitting the strip-shaped plate is received by the V-shaped blade tip member, and the received wind is flowed in the axial direction to increase the efficiency of the drag. Further, the V-shaped blade tip member is formed into a rounded V shape considering air resistance, and the plate side is recessed to a semicircular diameter. The width and thickness of the strip-shaped plate and the width and thickness of the V-shaped blade tip member are determined in consideration of air resistance, drag, and the like. Since the number and arrangement of blades have a great influence on the rotation, the way of the wind is determined so that the wind hits the blade. The rotor blade that supports the blade is streamlined considering air resistance. Use guide vanes, double centrifugal clutches, etc. In the double centrifugal clutch, a windmill that rotates by light wind is connected to the upper part, and a windmill that does not rotate by light wind is connected to the lower part. This helps the initial rotation of the lower windmill under the generator load.

本発明の請求項１、請求項２記載の垂直軸直線翼風車ブレードは微風で風車が回転する。又、ガイドベーン、ダブル遠心クラッチ等を設ける事により高速回転する。
本発明のブレード２本を吹き寄せにし３カ所に配置することに依り風車は高速回転しミニ風力発電用に適している。更に本発明のブレードは、従来の垂直軸直線翼風車ブレードと違い弱風の利用効率が高いのが特徴である。The vertical axis straight blade wind turbine blades according to claims 1 and 2 of the present invention rotate the wind turbine with a slight wind. In addition, it rotates at high speed by providing a guide vane, double centrifugal clutch, etc.
The wind turbine rotates at a high speed by arranging the two blades of the present invention together and arranged at three locations, and is suitable for mini wind power generation. Further, the blade of the present invention is characterized by high utilization efficiency of the weak wind unlike the conventional vertical axis straight blade wind turbine blade.

発明を実施するため最良の形態BEST MODE FOR CARRYING OUT THE INVENTION

本発明を実地形態に基づいて説明する。実施形態に係る風車ブレードを図１（斜視図）に示す。このブレードは短冊状プレート１、連結部材３、Ｖ字型ブレード先端部材２からなる物である。又、短冊状プレート１、Ｖ字型ブレード先端部材２の寸法の割合は、幅１０：３、厚みは１：５位とする。Ｖ字型ブレード先端部材２の形状は、丸みを持ったＶ字形にし、連結側は半円形に窪ませる。又、ブレードの長さに依り連結部材３、回転翼４の数を決める。The present invention will be described on the basis of a practical form. A wind turbine blade according to an embodiment is shown in FIG. 1 (perspective view). This blade is composed of a strip-shaped plate 1, a connecting member 3, and a V-shaped blade tip member 2. The ratio of the dimensions of the strip-shaped plate 1 and the V-shaped blade tip member 2 is 10: 3 in width and 1: 5 in thickness. The shape of the V-shaped blade tip member 2 is a rounded V shape, and the connection side is recessed in a semicircular shape. The number of connecting members 3 and rotor blades 4 is determined according to the length of the blade.

図２、図３（平面図）に示す、１、２、３からなるブレード７本に、回転翼４を取り付け、シャフト６、回転翼取り付け具５に回転翼４を取り付け垂直軸直線翼風車とする。A rotary blade 4 is attached to seven blades 1, 2, and 3 shown in FIGS. 2 and 3 (plan view), and a rotary blade 4 is attached to a shaft 6 and a rotary blade attachment 5. To do.

図４、（平面図）図５（正面図）に示す、垂直軸直線翼風車は、ブレード２本を吹き寄せにし３カ所に配置、高速回転する垂直軸直線翼風車の図である。4 (plan view) FIG. 5 (front view) shows a vertical axis linear blade wind turbine arranged at three locations with two blades blowing and rotating at high speed.

図６（平面図）、図７（正面図〉に示す垂直軸直線翼風車は、ブレード７本を等間隔に配置し、ガイドベーン７を５ヵ所設け、ガイドベーン付き風車上部板８でセットした垂直軸直線翼風車である。In the vertical axis straight blade wind turbine shown in FIG. 6 (plan view) and FIG. 7 (front view), seven blades are arranged at equal intervals, five guide vanes 7 are provided, and the wind turbine upper plate 8 with guide vanes is set. It is a vertical axis straight blade wind turbine.

本発明の垂直軸直線翼風車及びブレードを使用した実施例を説明する。ブレードの本数は、微風で回転させるのには６本〜７本が適当である。しかし回転を上げるのには風の利用効率を考えなければならない。特に垂直軸直線翼風車の場合、前方のブレードで風をせき止めないで、他のブレードにも推進力となる風を当てなければ成らない。その為にはブレードの数を減らさず２本のブレードを吹き寄せにし、３カ所に配置し間隔を広くする。そのことにより回転数が上がる。An embodiment using the vertical axis straight blade wind turbine and blade of the present invention will be described. The number of blades is suitably 6 to 7 for rotating with a light breeze. However, to increase the rotation, you must consider the efficiency of wind utilization. In particular, in the case of a vertical axis straight blade wind turbine, it is necessary not to block the wind with the blades in the front, but to apply wind as a driving force to the other blades. For this purpose, two blades are blown up without reducing the number of blades and arranged at three locations to widen the interval. This increases the rotational speed.

７本のブレードを等間隔に配置の場合ガイドベーンを設ける事により微風でも高速回転が得られる。発電機等の負荷により高速風車が微風での回転が困難の場合、低速風車と高速風車をダブル遠心クラッチで接続することにより回転がスムースになる。When seven blades are arranged at equal intervals, high-speed rotation can be obtained even with a slight wind by providing guide vanes. When the high-speed windmill is difficult to rotate with a slight wind due to a load such as a generator, the rotation is smooth by connecting the low-speed windmill and the high-speed windmill with a double centrifugal clutch.
