Description

【0001】
【発明の属する技術分野】
本発明は、風圧により自動開閉する羽根を垂直回転軸の回りに配置し、風を回転エネルギ−に効率良く転換する垂直軸型風車に関するものである。
【0002】
【従来の技術】
従来の垂直軸型風車はダリウス式、サポニュウス式が代表的に知られているがダリウス式は一般的に風速12m以上の強風時に揚力作用により回転するが、起動力が殆ど皆無である。又サポニウス式は弱風時においても起動可能で有るが、抗力と反抗力の差が少ないので低速回転となり極めて効率が悪いので殆ど実用化されていない。
【0003】
【発明が解決しようとする課題】
従来の垂直軸型風車のサポニウス式においては風を受ける抗力を風に向かう反抗力が打ち消すので効率が低下する。又強風時においては受風体面積の調整不能のため機械ブレ−キ,電磁ブレ−キ等により回転数を強制的に落とすので、羽根に強い力が加わり破損に至りやすい等の問題点が有った。
【0004】
本発明は弱風時においては大きな角度で風をうけ、強風時には小さな角度に開いた羽根で抗力を小さくし、低風速から高風速の広い範囲の風に即応し、極めて安全で効率の良い風車を提供する事を目的としている。
【0005】
【課題を解決するための手段】
上記の目的を達成するために、本発明の風圧開閉式垂直軸型風車においては、垂直軸の周辺に風圧により自動開閉する羽根を2〜4組、取付けて、抗力と反抗力の受風面積差を大きくし、弱風時に措いても効率良く回転する様にする。
【0006】
強風時にも安全回転が可能なように内部ビ−ムに、遠心力リング重りを取り付け過速度回転時に自動的に外周辺へ移動する力を利用して開閉調整引き紐を引くことにより羽根が強制的に閉鎖され、風に対する抵抗を減ずるので、より安全に風を通過させるので強風による風車の破壊を防止する。
【0007】
風圧自動開閉羽根は、風に向かっては風圧により、殆ど閉じて風に対する断面が薄く殆ど無抵力となる。羽根が風を受けると角度を大きく羽根を広げ抗力一杯に回転する。中間帯に位置する時は半開きとなり揚力作用をなす。
【0008】
風圧自動開閉羽根の内部に弱いスプリングを取り付けるか、もしくは羽根の外側にゴムバネ帯板、等を取り付けて羽根が平常時、外側へ開く様にしておく、無論、最適開閉度を越えない様に内側の調整用帯紐等により調整する。
【0009】
開閉羽根の外周を取り囲む様に円形の外輪を取り付ける事により構造に強度を確保し、尚且つフライホイルの代役をなさしめる事によりより効率を上げる。
【0010】
【発明の実施の形態】
発明の実施の形態を実施例にもとずき図面を参照して説明する。
図1において、垂直回転軸6を中心にして自転車のハブの様な円形の構造物9を取り付け、このハブ構造物に羽根取り付けア−ム2と、羽根内部ビ−ム3を取り付ける、此れらの外周に円形外輪10を取り付ける。
【0011】
図2に示される実施例では、開閉羽根1を羽根取り付けア−ム2、羽根内部ビ−ム3を挟み、組み立てる。開閉羽根1の上下板をヒンジリング12で連結し、外側に開閉用ゴムバネ帯板11を、取り付ける。
【0012】
開閉羽根1の内部に開閉調整引き紐5及び羽根内部ビ−ム3に遠心開閉重り4を通し開閉滑車7、をへて開閉リング8に結紐する。

BACKGROUND OF THE INVENTION
The present invention relates to a vertical axis wind turbine in which blades that automatically open and close by wind pressure are arranged around a vertical rotation axis, and wind is efficiently converted into rotational energy.
[0002]
[Prior art]
Conventional vertical axis type wind turbines are typically known as Darius type and Saponius type, but Darius type generally rotates by a lift action at the time of a strong wind of 12 m or more, but has almost no starting force. The Saponius type can be started even in low winds, but since the difference between the drag and the reaction force is small, the speed is low and the efficiency is very low.
[0003]
[Problems to be solved by the invention]
In the Saponius type of a conventional vertical axis type wind turbine, the drag force against the wind cancels out the drag force against the wind, so the efficiency is lowered. In addition, the wind receiving area cannot be adjusted during strong winds, so the rotational speed is forcibly reduced by mechanical brakes, electromagnetic brakes, etc., and there is a problem that a strong force is applied to the blades, leading to breakage. It was.
[0004]
The present invention winds at a large angle during low winds, reduces the drag with blades opened at a small angle during strong winds, responds quickly to a wide range of winds from low to high wind speeds, and is extremely safe and efficient. The purpose is to provide.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, in the wind pressure open / close type vertical axis wind turbine of the present invention, 2 to 4 sets of blades that automatically open and close by the wind pressure are mounted around the vertical axis, and the wind receiving area of the drag and reaction force Increase the difference so that it rotates efficiently even if it is taken in a low wind.
[0006]
A centrifugal force ring weight is attached to the internal beam so that safe rotation is possible even in strong winds, and the blades are forced by pulling the opening / closing adjustment drawstring using the force that automatically moves to the outer periphery during overspeed rotation. The wind turbine is closed and the resistance to wind is reduced, so that the wind can be passed more safely, thereby preventing the wind turbine from being destroyed by strong wind.
[0007]
The wind pressure automatic opening / closing blade is almost closed due to the wind pressure toward the wind, and the cross section with respect to the wind is thin and almost free of force. When the blade receives the wind, it widens the angle and spreads the blade to full force. When it is located in the middle belt, it is half-opened and has a lifting effect.
[0008]
Install a weak spring inside the wind pressure automatic opening / closing blade, or attach a rubber spring strip, etc. on the outside of the blade so that the blade opens in the normal state, of course, inside so as not to exceed the optimum opening / closing degree. Adjust with an adjustment strap.
[0009]
By attaching a circular outer ring so as to surround the outer periphery of the opening and closing blades, the structure is secured, and the efficiency is improved by substituting the flywheel.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the invention will be described based on an example with reference to the drawings.
In FIG. 1, a circular structure 9 such as a bicycle hub is mounted around a vertical rotation axis 6, and a blade mounting arm 2 and a blade inner beam 3 are mounted on the hub structure. A circular outer ring 10 is attached to the outer periphery.
[0011]
In the embodiment shown in FIG. 2, the opening / closing blade 1 is assembled by sandwiching the blade mounting arm 2 and the blade inner beam 3. The upper and lower plates of the opening / closing blade 1 are connected by a hinge ring 12, and an opening / closing rubber spring strip 11 is attached to the outside.
[0012]
The opening / closing adjustment pull string 5 and the blade inner beam 3 are passed through the centrifugal opening / closing weight 4 and the opening / closing pulley 7 is connected to the opening / closing ring 8.
[0013]
【The invention's effect】
Since the present invention is configured as described above, the following effects can be obtained.
[0014]
By attaching an openable / closable blade to the vertical rotating shaft, it can efficiently receive and rotate even in low winds.
[0015]
Safe rotation speed control is possible even with an overspeed rotation during strong winds by the centrifugal force application automatic opening and closing device.
[0016]
A flywheel effect can be expected by attaching the outer ring of the blade. ,
[0017]
Can respond immediately to wind from all directions. It can handle a wide range of wind speed changes from low speed to high speed.
[0018]
There is no need for high tower pillars like propeller type wind turbines, and there is very little risk of lightning strikes.
[0019]
Because the wind noise is small, it can be installed on the rooftop of a building in the city.
[0020]
Since the shape of the blade is simple, the design is relatively easy.
[0021]
When the output is increased, it can be easily increased by stacking several wind units.
