Abstract

<P>PROBLEM TO BE SOLVED: To improve the shape and arrangement of the object to increase the rotation of a blade by solving a problem in a vertical shaft windmill wherein when an object is placed at the front of the blade, the rotation of the blade is affected and compensate for the acceleration force of lift type blade used for the vertical shaft windmill by forming it in a hook shape in cross section since the blade is poor in the acceleration force. <P>SOLUTION: When a straightening plate 1 is disposed at an angle relative to its centerline, a straightening effect and wind collecting effect occur, and the rotational speed of the blade 2 is increased more than that in a state where the straightening plate is absent. By forming the cross section of the blade 2 in the hook shape, its acceleration performance is increased, and a high speed rotation is enabled by an auxiliary blade. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

この発明は、垂直軸風車の羽根の外周に整流板を配置した風車と、その風車に使用する断面が鉤形をした羽根に関するものである。  The present invention relates to a wind turbine in which a current plate is arranged on the outer periphery of a blade of a vertical axis wind turbine, and a blade having a bowl-shaped cross section used for the wind turbine.

風車において、風を受ける羽根の前面に物体を置くと、回転に悪影響を及ぼす。
垂直軸風車の揚力型の羽根は加速力が悪い。In a windmill, placing an object in front of a blade that receives wind adversely affects rotation.
Lifting blades of vertical axis wind turbines have poor acceleration.

風車において、風を受ける羽根の前面に物体を置けば、その物体が風の流れを止めたり、乱したりして羽根の回転に悪影響を及ぼす。
本発明は、風を受ける羽根の前面に物体を置いても、羽根の回転に悪影響を及ぼさないように、その物体の形状と、配置を工夫したものである。In a windmill, when an object is placed in front of a blade that receives wind, the object stops or disturbs the flow of the wind and adversely affects the rotation of the blade.
In the present invention, the shape and arrangement of an object are devised so that even if an object is placed in front of a blade that receives wind, the rotation of the blade is not adversely affected.

垂直軸風車の羽根の外周に整流板を配置する。
整流板を固定する場合は、図２に示すように整流板１を中心線に対して、約１０〜３０度の角度をつけて配置し固定する。
整流板を可動させる場合は、図４に示すようにまず支柱９を固定して、その支柱９に整流板（可動式）１０を可動するように取り付ける、整流板１０の左右の位置にストッパー８を配置して固定し、整流板１０が左右のストッパー８の範囲内の角度で可動するようにする。
整流板の形状は、図１０の平板形、図１１の「く」の字形、図１２の「し」の字形、図１３の弧形である。
鉤形の羽根は図７に示すように図５のＢ−Ｂ部断面が鉤の形をした羽根である。
本発明は以上のような構成よりなる整流式風車である。A rectifying plate is disposed on the outer periphery of the blade of the vertical axis wind turbine.
When the current plate is fixed, the current plate 1 is arranged and fixed at an angle of about 10 to 30 degrees with respect to the center line as shown in FIG.
When the rectifying plate is moved, as shown in FIG. 4, first, the support column 9 is fixed, and the rectifying plate (movable) 10 is attached to the support column 9 so that the rectifying plate 10 is movable. Is arranged and fixed so that the current plate 10 can move at an angle within the range of the left and right stoppers 8.
The shape of the current plate is the flat plate shape of FIG. 10, the “ku” shape of FIG. 11, the “shi” shape of FIG. 12, and the arc shape of FIG.
As shown in FIG. 7, the hook-shaped blade is a blade whose cross section taken along the line BB in FIG. 5 has a hook shape.
The present invention is a rectifying wind turbine having the above-described configuration.

整流板を、図２のように中心線に対して角度をつけて配置し固定した場合、整流効果、集風効果が発生し、整流板がない状態と比較すると羽根の回転は増加する。
整流板が可動式の場合は、風の力によって整流板が、ストッパーの間を動いて中心線に対して角度がついた状態となる。
整流板によって風車全体の強度が増加する。
整流板によって羽根の回転軸を受け止める軸受を、複数個所に設置できる。
整流板によって風車全体の強度が増加し、軸受を複数個所に設置できることにより垂直軸の風車においても、風車の直径を大きくしたり、羽根を高くしたりすることが可能となる。
鉤形の羽根は加速性能がよくなる、さらに動く構造の補助翼１２（図８）を取り付ければ遠心力によって揚力翼の形状になり、高速回転に適した羽根の形状となる。When the rectifying plate is arranged and fixed at an angle with respect to the center line as shown in FIG. 2, the rectifying effect and the wind collecting effect are generated, and the rotation of the blades is increased as compared with the state without the rectifying plate.
When the rectifying plate is movable, the rectifying plate is moved between the stoppers by the wind force, and is in an angled state with respect to the center line.
The current plate increases the strength of the wind turbine as a whole.
Bearings that receive the rotating shafts of the blades by the current plate can be installed at a plurality of locations.
The strength of the entire wind turbine is increased by the current plate, and the bearings can be installed at a plurality of locations, so that even in a vertical axis wind turbine, the diameter of the wind turbine and the blades can be increased.
The saddle-shaped blade has improved acceleration performance, and if the auxiliary blade 12 (FIG. 8) having a moving structure is further attached, it becomes a shape of a lift blade by centrifugal force and a shape of a blade suitable for high-speed rotation.
