Description
本発明は、可動翼を備える縦軸型直線翼風車に関し、詳しくは、過回転問題および始動性能の低さを改善するために風車の回転を空力的に調速する機構を備える縦軸型直線翼風車に関する。 More specifically, the present invention relates to a vertical axis linear turbine including a mechanism for aerodynamically adjusting the rotation of the wind turbine in order to improve over-rotation problems and low starting performance. It relates to a wing windmill.
一般に、風力発電用の風車は、オランダ型風車に代表されるような、風に対して回転軸が水平になっている水平軸型風車と、風に対して回転軸が垂直になっている垂直軸型風車（即ち縦軸型風車）が知られている。また、縦軸型風車は、サボニウス型に代表される効力型と、直線翼風車（すなわち縦軸型直線翼風車）に代表される揚力型に分類される。 In general, wind turbines for wind power generation include horizontal axis type wind turbines whose rotation axis is horizontal with respect to the wind, as represented by Dutch type wind turbines, and vertical axes whose rotation axis is perpendicular to the wind. An axial wind turbine (that is, a vertical wind turbine) is known. The vertical wind turbine is classified into an effective type represented by a Savonius type and a lift type represented by a straight blade wind turbine (that is, a vertical straight wind turbine).
このうち、縦軸型直線翼風車は、回転始動性が水平軸型風車に比べて劣るものの、ひとたび回転し始めると、風を受けている限り回転トルクを発生し続け、回転が加速度的に上昇する特徴がある。このことから、縦軸型直線翼風車は小型で高い発電能力を得られる発電用風車として有望視されており、今後、始動性の改善により普及が更に広がるものと考えられる。 Of these, the vertical axis straight-blade wind turbine is inferior in rotational startability to the horizontal axis wind turbine, but once it starts rotating, it continues to generate rotational torque as long as it receives wind, and the rotation increases at an accelerated rate. There is a feature to do. For this reason, the vertical-axis type linear blade wind turbine is regarded as promising as a wind turbine for power generation that is small and has high power generation capability, and it is considered that the spread of the vertical axis wind turbine will be further expanded by improving the startability in the future.
しかし、その反面、縦軸型直線翼風車の加速度的な回転上昇は、故障、破壊につながる過回転を招くため、その抑制手段が必要とされている。 However, on the other hand, since the rotational increase of the vertical linear wind turbine is accelerated, it leads to over-rotation that leads to failure and destruction, so that a suppression means is required.
縦軸型直線翼風車の過回転を抑制する手段は、既にいくつか知られており、たとえば、風車の回転軸に摩擦力を加え、機械的に減速、静止する方法や、風車に接続される発電機を制御し、渦電流により減速、静止する方法が実用化されている。
上記の方法は、風を受けて発生する回転トルクに対し、摩擦力や渦電流ブレーキといった制動力を加え、回転を制動力と回転力のつり合いにより抑制する原理である。この原理は、風を受け続けることにより回転トルクが発生し続けた場合、制動力の限界に対して回転力が大きく上回り、回転の抑制ができなくなるおそれがある。このため、極強風時には、風車の回転を停止する措置をとられることがあった。
Several means are already known for suppressing the over-rotation of the vertical axis type straight-blade wind turbine. For example, a method of applying a frictional force to the rotation shaft of the wind turbine to mechanically decelerate and stop, or connected to the wind turbine. A method of controlling a generator and decelerating and stopping by an eddy current has been put into practical use.
The above method is a principle that suppresses rotation by balancing the braking force and the rotational force by applying a braking force such as a frictional force or an eddy current brake to the rotational torque generated by receiving the wind. According to this principle, when the rotational torque continues to be generated by continuing to receive wind, the rotational force greatly exceeds the limit of the braking force, and the rotation may not be suppressed. For this reason, measures have been taken to stop the rotation of the windmill during extreme winds.
また、制動力と回転力のつり合いを利用しない縦軸型直線翼風車の過回転抑制手段として、翼を可動翼とし、可動翼のピッチ角を変更することにより、風により発生する回転トルクを減らす方法が知られている（例えば、特許文献１参照。）。この方法は、制動力を加えないことから、制動力の限界を考慮する必要がないため、強風時の風車の停止、すなわち発電の停止を極力避けることができる利点がある。また、可動翼のピッチ角の変更は、強風時に限らず可能なため、始動時においても回転トルクの制御ができる利点がある。 In addition, as a means for suppressing over-rotation of a vertical-axis linear blade wind turbine that does not use the balance between braking force and rotational force, the rotational torque generated by the wind is reduced by changing the pitch angle of the movable blade as the movable blade. A method is known (for example, refer to Patent Document 1). Since this method does not apply a braking force, there is no need to consider the limit of the braking force, and therefore there is an advantage that it is possible to avoid as much as possible the stop of the windmill in a strong wind, that is, the stop of power generation. Further, since the pitch angle of the movable blade can be changed not only in a strong wind, there is an advantage that the rotational torque can be controlled even at the start.
従来技術において縦軸型直線翼風車の可動翼のピッチ角を変更する手段は、例えば、特許文献１に提案されるように、モーター等、電動機の動力を必要とするものが知られている。これは、ピッチ角を変更するための電動機を、商用電源や電源の補助である蓄電池により作動させる必要があり、商用電源の停電や蓄電池の電圧不足によっては、制御不能となるおそれがある。また、停電となる確率は、強風や暴風雨などの悪天候時が高く、また、天候悪化時にメンテナンスをすることは容易ではない。このため、安全を保ち、管理面を向上する、新たな縦軸型直線翼風車が求められていた。 In the prior art, as a means for changing the pitch angle of the movable blades of the vertical type linear blade wind turbine, for example, as proposed in Patent Document 1, a device that requires the power of an electric motor such as a motor is known. This requires that an electric motor for changing the pitch angle be operated by a commercial power source or a storage battery that is an auxiliary to the power source, and may become uncontrollable due to a power failure of the commercial power source or a shortage of the storage battery voltage. In addition, the probability of a power outage is high during bad weather such as strong winds and storms, and maintenance is not easy when the weather deteriorates. For this reason, there has been a demand for a new vertical axis wind turbine that maintains safety and improves management.
本発明者は、上記課題を実現するために研究した結果、可動翼の角度を風車の回転動作により自律的に制御する技術に到達した。すなわち、本発明の目的は、可動翼のピッチ角を変更して風車の回転を空力的に調速する縦軸型直線翼風車において、モーター等の電動機の動力を用いずにピッチ角を調節し、かつ、回転の状況により、ピッチ角が自律的に制御される縦軸型直線翼風車を提供することにある。 As a result of researches for realizing the above-mentioned problems, the present inventor has arrived at a technique for autonomously controlling the angle of the movable blade by the rotating operation of the windmill. That is, an object of the present invention is to adjust the pitch angle without using the power of an electric motor such as a motor in a vertical axis linear blade wind turbine that aerodynamically adjusts the rotation of the wind turbine by changing the pitch angle of the movable blade. And it is providing the vertical axis | shaft type linear blade wind turbine by which a pitch angle is autonomously controlled by the condition of rotation.

In addition, since the autonomous over-rotation suppression mechanism does not require manual operations such as stopping and storing when the weather suddenly changes to a strong wind, it can reduce the operating cost of the wind turbine that comes from labor costs. For this reason, installation in high places such as mountainous areas, building walls, steel towers, etc., where work is not easy, is effective. Further, the over-rotation suppressing mechanism of the present invention is not mechanical braking by frictional force but is an aerodynamic mechanism by blades that are absolute elements of a windmill, so that the structure is simple and can be made compact. This also leads to a reduction in manufacturing costs. In addition, the operation of the movable blade of the present invention is not limited to the suppression of over-rotation, but can improve startability.
以下、図面を参照して本発明の実施形態を説明する。なお、これにより本発明が限定されるものではない。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited thereby.
（第１の実施の形態）
図７に、第１の実施の形態に係る縦軸型直線翼風車の概略図を示す。これは、回転軸２０の上部と下部に、円板５０を固定し、二枚の円板５０で、回転軸に平行に可動翼１０を挟み込む形の縦軸型直線翼風車である。この風車は回転軸２０に外接する軸受け（図示しない）により回転する。また、円板５０には、可動翼軸１１を差し込む孔が設けられ、この孔を支点に可動翼１０は作動する。可動翼１０の作動範囲は、可動翼の後端部（回転方向と逆側の可動翼端）の延長軸１３が、円板５０に設けるガイド５１に内接することにより制限される。なお、可動翼１０は、可動翼軸１１に対し、後端部の重量が、前端部（回転方向側の可動翼端）に比べ大きいため、回転の際に生じる遠心力は、後端部が遠心方向にはらむ作動となる。図８に、図７の上部からみた概略図を示す。
(First embodiment)
FIG. 7 shows a schematic view of a vertical axis type linear blade wind turbine according to the first embodiment. This is a vertical axis type linear blade wind turbine in which a disk 50 is fixed to an upper part and a lower part of a rotating shaft 20 and a movable blade 10 is sandwiched between two disks 50 in parallel to the rotating shaft. The windmill is rotated by a bearing (not shown) circumscribing the rotating shaft 20. Further, the disc 50 is provided with a hole into which the movable blade shaft 11 is inserted, and the movable blade 10 operates with this hole as a fulcrum. The operating range of the movable blade 10 is limited by the extension shaft 13 of the rear end portion (movable blade end opposite to the rotation direction) of the movable blade being inscribed in the guide 51 provided on the disk 50. In addition, since the movable blade 10 is larger in weight than the front end (movable blade end on the rotation direction side) with respect to the movable blade shaft 11, the centrifugal force generated during the rotation of the movable blade 10 at the rear end is large. It becomes the operation which goes into the centrifugal direction. FIG. 8 shows a schematic view seen from the top of FIG.
（第２の実施の形態）
図９に、第２の実施の形態に係る縦軸型直線翼風車の概略図を示す。これは、第１の実施の形態に係る縦軸型直線翼風車の円板５０の上部に、可動翼の作動を自律的に制御する機構を組み込むものである。可動翼軸１１と可動翼の後端部の延長軸１３を結ぶ形で、作用棒１４を固定し、その作用棒１４の、可動翼の後端部側端におもり４０を固定する。また、回転軸２０にリング２１を外接し、作用棒１４とリング２１をシャフト２２によりリンクする。それぞれの可動翼に対し、上記リンクを行うことにより、複数の可動翼の作動をリング２１の回転を介して連動することができる。
リング２１には、一端を円板５０上に固定する弾性体３１を接続する。弾性体３１は縮みの復元力を生じるバネであり、作用棒１４がシャフト２２を介して内側に引っ張られるように、リング２１に復元力を伝達する。リング２１は、遠心力の発生していない風車の静止状態で、延長軸１３がガイド５１の内側方向の限界となる位置にて静止する。この位置で静止することにより、可動翼は風の力を回転力として受けやすい方向となる。
(Second Embodiment)
FIG. 9 is a schematic view of a vertical axis type linear blade wind turbine according to the second embodiment. In this configuration, a mechanism for autonomously controlling the operation of the movable blade is incorporated in the upper part of the disc 50 of the vertical linear blade turbine according to the first embodiment. An action rod 14 is fixed in a form connecting the movable blade shaft 11 and the extension shaft 13 of the rear end portion of the movable blade, and a weight 40 is fixed to the end of the action blade 14 on the rear end side of the movable blade. Further, a ring 21 is circumscribed on the rotary shaft 20, and the action rod 14 and the ring 21 are linked by a shaft 22. By performing the above link for each movable blade, the operations of the plurality of movable blades can be linked through rotation of the ring 21.
An elastic body 31 that fixes one end on the disc 50 is connected to the ring 21. The elastic body 31 is a spring that generates a restoring force for contraction, and transmits the restoring force to the ring 21 so that the action rod 14 is pulled inward via the shaft 22. The ring 21 is stationary at a position where the extension shaft 13 becomes the limit in the inner direction of the guide 51 in a stationary state of the windmill in which centrifugal force is not generated. By stationary at this position, the movable wing is in a direction in which it is easy to receive wind force as rotational force.
風車が風を受けて回転し始めると、おもり４０と可動翼に遠心力が生じ、可動翼軸１１を支点にして、外側にはらます力となる。この遠心力と弾性体３１の縮もうとする復元力との釣り合いにより、可動翼の角度が自律的に決定する。可動翼が外側にはらみ、作用棒１４が弾性体３２と接している状態図を図１０に示す。弾性体３２は、伸びの復元力を生じるばねであり、風車の外側方向の端が円板５０上に固定される。なお、図９および図１０に示す状態が、弾性体３２の自然長の状態である。 When the windmill begins to rotate in response to wind, centrifugal force is generated in the weight 40 and the movable blade, and the force is applied to the outside with the movable blade shaft 11 as a fulcrum. The angle of the movable blade is autonomously determined by the balance between the centrifugal force and the restoring force to be contracted by the elastic body 31. FIG. 10 shows a state diagram in which the movable wing is held outward and the action rod 14 is in contact with the elastic body 32. The elastic body 32 is a spring that generates a restoring force of elongation, and the end in the outer direction of the windmill is fixed on the disc 50. The state shown in FIGS. 9 and 10 is the natural length state of the elastic body 32.
図１０の状態から更に回転が上昇すると、おもり４０と可動翼に生じる遠心力が増大し、弾性体３２を縮めながら可動翼を外側にはらます。可動翼が外側にはらむ様子を図１１に示す。可動翼は、外側にはらむことにより、風の力を回転力として受けにくい状態となるため、回転上昇が抑えられる。 When the rotation further increases from the state of FIG. 10, the centrifugal force generated in the weight 40 and the movable wing increases, and the movable wing is moved outward while the elastic body 32 is contracted. FIG. 11 shows a state in which the movable wing is caught outward. The movable wings are not easily received as a rotational force by being caught on the outside, so that the increase in rotation is suppressed.
