Description

風車が無風時から強風時まであらゆる風況に対し確実に機能し、また発電量を増やすための工夫を施した風車に関する。また、同様メカニズムを具備した水車に関する。双方のメカニズムは共通するので以下では風車を例として記述する。 The present invention relates to a wind turbine that functions reliably for all wind conditions from when there is no wind to when it is strong and has been devised to increase the amount of power generation. Moreover, it is related with the water turbine which comprised the same mechanism. Since both mechanisms are common, a windmill is described below as an example.

並進翼風車のピッチ角は風向とブレード翼弦が平行の時を0度と定義する。風力が強まるに従い、過回転の防止あるいは回転数を一定にする等のために並進翼風車のピッチ角は小さくなるように制御される。特願２００２−０７１２７０の構造では、ピッチ角が0度に近づくとピッチガイド溝とピッチアームとのクリアランスにより角度設定誤差が大きくなる。ピッチ角0度の時はピッチアームとガイド溝は90度の配置となり、この状態からピッチ角を変えようとしてもピッチアームがガイド溝に直角になっているためガイド溝を動かす事ができないかあるいはピッチ角がプラス側マイナス側いづれに動くか定まらない。従って、ピッチ角が0度近くまで小さくなりその後風力が弱まりピッチ角をプラス側に大きくしようとしても、一部ブレードのピッチ角がマイナス側に設定されてしまうことも起こり得るので、その防止方法が必要である。また、ピッチ角が0度付近に至った状態で風が止まった後、風が再度吹き始めた時風車が起動するためには、ブレードピッチ角は起動に必要なトルクを発生できる角度になっている必要がある。そのために、モーター等の外部動力によりピッチ角を強制設定する方法もあるが、それはエネルギー消費となるので起動・停止・再起動を外部動力を用いずに実現する方法が必要である。 The pitch angle of a translation blade wind turbine is defined as 0 degrees when the wind direction and blade chord are parallel. As the wind force becomes stronger, the pitch angle of the translational blade wind turbine is controlled to become smaller in order to prevent over-rotation or to keep the rotation speed constant. In the structure of Japanese Patent Application No. 2002-071270, when the pitch angle approaches 0 degrees, the angle setting error increases due to the clearance between the pitch guide groove and the pitch arm. When the pitch angle is 0 degree, the pitch arm and the guide groove are 90 degrees, and even if you try to change the pitch angle from this state, the pitch arm is perpendicular to the guide groove, so the guide groove can not be moved or It is not determined whether the pitch angle moves on the plus side or the minus side. Therefore, even if the pitch angle is reduced to near 0 degrees and the wind force is weakened and the pitch angle is increased to the plus side, the pitch angle of some blades may be set to the minus side. is necessary. In addition, when the wind stops after the pitch angle has reached around 0 degrees and the wind starts to blow again, the blade pitch angle is an angle that can generate the torque required for startup. Need to be. For this purpose, there is a method of forcibly setting the pitch angle by external power such as a motor. However, since this consumes energy, a method for realizing start / stop / restart without using external power is necessary.

ブレードのピッチ角はピッチアームをアームガイド溝に沿って動かすことにより制御する方法と、風力あるいは水力とバネ等の弾性力との釣合いで設定する方法があるが、後者の場合は弾性力を可変としなければ最適ピッチ角が設定できない。 The pitch angle of the blade can be controlled by moving the pitch arm along the arm guide groove, or can be set by the balance between wind power or hydraulic power and elastic force such as springs. In the latter case, the elastic force can be varied. Otherwise, the optimum pitch angle cannot be set.

受風面積が決められた場合、発電量を増やすには風車効率を上げる方法と、風車に流れ込む風量を増やす方法とがある。風車効率向上には多くは期待できないので、風量増加の方法が必要である。 When the wind receiving area is determined, there are a method of increasing the wind turbine efficiency and a method of increasing the amount of wind flowing into the wind turbine in order to increase the power generation amount. Since much cannot be expected to improve wind turbine efficiency, a method for increasing the air flow is necessary.

特願２００２−０７１２７０ではブレード駆動索の撓みをブレードあるいは駆動索にベアリング等を付加する方法で防いでいるが、装置躯体に取り付けたローラーで受けることにより装置構造が簡略になる。 In Japanese Patent Application No. 2002-071270, the blade drive cable is prevented from being bent by a method of adding a bearing or the like to the blade or the drive cable. However, the structure of the device is simplified by receiving it with a roller attached to the device housing.

特願２００２−０７１２７０ではブレード駆動索を主スプロケットに掛け回し、スプロケット軸を出力軸としているが、大型装置では大型スプロケットが必要となり製造が難しくなる。 In Japanese Patent Application No. 2002-071270, the blade drive cord is wound around the main sprocket and the sprocket shaft is used as the output shaft. However, a large-sized device requires a large sprocket and is difficult to manufacture.

受風面積を任意に変更できれば、弱風時には面積を広げ、強風時には面積を狭めることにより安定的に電力を得ることができる。 If the wind receiving area can be arbitrarily changed, the power can be stably obtained by widening the area when the wind is weak and narrowing the area when the wind is strong.

国内の風況は、概して風向変化が激しいと言われ、風向変化への追従性の良い風車が必要であり、そのためにはジャイロモーメントの小さい風車が必要である。
牛山泉、他著 「小型風車ハンドブック」 パワー社 １９８０年 The wind conditions in Japan are generally said to have a rapid change in wind direction, and a windmill with good followability to the change in wind direction is required. To that end, a windmill with a small gyro moment is required.

本発明は、バネ等の弾性体の復元力を利用することによりピッチ角0度からの回転復帰を行う方法、ブレードピッチ角設定に弾性力を使う場合に弾性体取り付け部を可動とする方法およびローター後流側の圧力を低くしローター前後での圧力勾配を大きくすることでローターに流れ込む風量を増す方法および躯体側にローラーを取り付けブレード駆動索の撓みを防ぐ方法、主スプロケットをアイドラーとし大径のプーリー等を用いる方法、ブレードを入れ子構造として受風面積を可変とする方法、一対の風車を併置し互いのローター回転方向を逆転することでジャイロモーメントをキャンセルし全体としてのジャイロモーメントをゼロにする方法、風車の自重を磁気反発力で支えベアリングに加わる重量負荷を軽減することによりタワー周りの回転し易さを向上させる方法を採る。 The present invention relates to a method of performing rotational recovery from a pitch angle of 0 degrees by utilizing a restoring force of an elastic body such as a spring, a method of moving an elastic body mounting portion when using an elastic force for setting a blade pitch angle, and A method of increasing the airflow flowing into the rotor by lowering the pressure on the wake side of the rotor and increasing the pressure gradient before and after the rotor, a method of installing a roller on the housing side to prevent bending of the blade drive cable, and a main sprocket with an idler for large diameter The method using a pulley, etc., the method of making the wind receiving area variable by nesting the blades, canceling the gyro moment by placing a pair of wind turbines in parallel and reversing the rotation direction of the rotors, and reducing the gyro moment as a whole The wind turbine's own weight is supported by magnetic repulsion and the weight load on the bearing is reduced to reduce the weight around the tower. Use a method to improve the ease of rotation.

ピッチ角0度からの復帰が確実に行えることにより、風のエネルギー豊富な強風時にも風車を稼働させる事ができ、かつその後の風力弱まりへも連続的に風車が機能できるため風のエネルギーを無駄なく吸収できる。ブレードのピッチ角制御により風車あるいは水車の最良な性能を利用できる。また、風車の大きさを変えることなく風車に流れ込む風量を増すことができ、発電量を増やす事ができる。垂直軸並進翼機形態（ブレードが垂直）の場合、ブレード駆動索の撓み防止は主スプロケットと駆動索との滑らかな掛け回しには不可欠であり、また駆動索がスプロケットから外れてしまい風車あるいは水車として機能しなくなる原因の除去となる。並進翼風車あるいは並進翼水車が大型化した場合、大型の主スプロケットの製造は容易ではない。スプロケットの代わりにプーリー等のアイドラーを用いブレード駆動索を掛け回し別の小径スプロケットを駆動索に作用させて回転力を引き出すことにより大型の並進翼風車、並進翼水車が技術的のみならず製造コストの点からも現実的なものと成る。さらに、小径スプロケットは増速器としても働き高い回転数を引き出すことができる。日本国内の風は風向偏向が頻繁であることから風向偏向への追従性の良い風車は、風に正対できるので効率よくエネルギー吸収ができ、また従来諦められていた場所での風力利用を可能とする。 By reliably returning from a pitch angle of 0 degrees, the wind turbine can be operated even in strong winds with abundant wind energy, and wind energy is wasted because the wind turbine can continuously function even after the wind is weakened. Can be absorbed. By controlling the pitch angle of the blade, the best performance of the windmill or water turbine can be used. Further, the amount of air flowing into the windmill can be increased without changing the size of the windmill, and the amount of power generation can be increased. In the case of a vertical-axis translation wing (blade is vertical), prevention of blade drive cable deflection is essential for smooth laying of the main sprocket and drive cable, and the drive cable comes off the sprocket and wind turbine or water turbine. As a result, the cause of failure will be removed. When the translation blade wind turbine or the translation blade turbine is enlarged, it is not easy to manufacture a large main sprocket. Large translation blade wind turbines and translation blade turbines are not only technically manufactured but also costly by using idlers such as pulleys instead of sprockets and wrapping the blade drive cable to make another small-diameter sprocket act on the drive cable to extract the rotational force. From this point, it becomes realistic. Furthermore, the small-diameter sprocket also works as a speed increaser and can extract a high rotational speed. Since wind in Japan is frequently deflected, wind turbines with good follow-up to wind direction can be directly opposed to the wind, so they can absorb energy efficiently and can be used in places that have been praised in the past. And

図１は請求項１あるいは２の実施例である。並進翼風車ブレードのピッチ角はピッチアーム３とピッチコントロールガイド溝４の位置関係により設定される。図１はピッチ角0度ないし0度に近い状態である。リミッター板１はピッチ角が0度に近づくと４に接触し、さらに角度が小さくなるに従い１の弾性反発力が増すので、ピッチ角が0度になってもブレード２がマイナスのピッチ角を取ることはない。ピッチコントロールガイド溝４はピッチコントロール棒５とラック/ピニオン等で連接され５の回転により４は駆動されるが、５に取り付けられたコイルバネ６は、中立状態（無風時の所期ピッチ角状態＝捩りエネルギー0の状態）のピッチ角からの捩れ角の大きさに応じ６の回転を中立状態に復帰させる復元力を発生する。中立状態は風車の起動トルクが得られるピッチ角度が選定される。風車回転開始後のピッチ角制御は発電シーケンスに応じ選定されるが、本発明では、特に強風時からその後の常用風速時への風車の自動的作動を実現することに重点を置く。過回転状態にならないようにするピッチ角制御はたとえば回転遠心力を利用した機械的調速機を使用し５を駆動してピッチ角を小さくする。図２はブレードがピッチ角0度に近づいてもピッチ角を保持できる別の機構例である。コイルバネ１３をブレード軸１５をバネ中心にしてバネの一端をブレード２あるいはピッチアーム３に他端をブレード駆動索１４に固定する。 FIG. 1 shows an embodiment of the first or second aspect. The pitch angle of the translation blade windmill blade is set by the positional relationship between the pitch arm 3 and the pitch control guide groove 4. FIG. 1 shows a state in which the pitch angle is 0 ° to close to 0 °. The limiter plate 1 comes into contact with 4 when the pitch angle approaches 0 degrees, and the elastic repulsion force of 1 increases as the angle becomes smaller, so the blade 2 takes a negative pitch angle even when the pitch angle becomes 0 degrees. There is nothing. The pitch control guide groove 4 is connected to the pitch control rod 5 by a rack / pinion or the like, and 4 is driven by the rotation of 5, but the coil spring 6 attached to 5 is in a neutral state (the desired pitch angle state without wind = A restoring force for returning the rotation of 6 to the neutral state is generated according to the magnitude of the torsion angle from the pitch angle of the torsional energy 0 state. In the neutral state, a pitch angle at which the wind turbine starting torque is obtained is selected. The pitch angle control after the start of the windmill rotation is selected according to the power generation sequence. In the present invention, however, an emphasis is placed on realizing the automatic operation of the windmill from the time of strong wind to the subsequent normal wind speed. For controlling the pitch angle so as not to be in an over-rotation state, for example, a mechanical speed governor using a rotating centrifugal force is used to drive 5 to reduce the pitch angle. FIG. 2 shows another example of the mechanism that can maintain the pitch angle even when the blade approaches the pitch angle of 0 degrees. The coil spring 13 is fixed at one end of the spring to the blade 2 or the pitch arm 3 and the other end to the blade drive cable 14 with the blade shaft 15 as the spring center.

図２を請求項３の実施例の説明に流用する。この場合は、コイルバネ１３の一端はブレード２に他の一端はピッチアーム３に固定される。また、１５と３とは回転自由に嵌合している。従って、ブレードのピッチ角はコイルバネ１３の弾性力と風力あるいは水力との釣合いで決まる。その状態から、ピッチコントロールガイド溝４を左右に移動すると１３の弾性力が変わりそれに応じピッチ角も変わる。 FIG. 2 is used for explaining the embodiment of claim 3. In this case, one end of the coil spring 13 is fixed to the blade 2 and the other end is fixed to the pitch arm 3. Further, 15 and 3 are fitted in a freely rotating manner. Therefore, the pitch angle of the blade is determined by the balance between the elastic force of the coil spring 13 and the wind force or hydraulic force. From this state, when the pitch control guide groove 4 is moved left and right, the elastic force 13 changes and the pitch angle changes accordingly.

図３は請求項４の実施例である。風車を通過する風量を増すために風車前後での圧力差を大きくする。エジェクター８は風を風車背後に誘導し背後の流速を高め静圧を下げる働きをし風車前後の圧力差を大きくする。また、スポイラー９は、スポイラー背後に圧力の低い剥離領域を作るため風車背後の圧力が低下する。
図４は請求項４の別の実施例である。風と並行に動くブレード（Bc,Bd）のピッチ角を風を風車内に取り込むように設定することで風量を増やす事ができる。 FIG. 3 shows an embodiment of claim 4. In order to increase the amount of air passing through the windmill, the pressure difference before and after the windmill is increased. The ejector 8 guides the wind behind the windmill to increase the flow velocity behind it and lower the static pressure, thereby increasing the pressure difference between the windmill and the windmill. Moreover, since the spoiler 9 makes the peeling area | region with a low pressure behind a spoiler, the pressure behind a windmill falls.
FIG. 4 shows another embodiment of the present invention. The air volume can be increased by setting the pitch angle of the blades (Bc, Bd) moving in parallel with the wind so that the wind is taken into the windmill.

図５は請求項５の実施例である。ブレード駆動索１４をローラー１６で受けることにより１４の撓みを防ぐ事ができる。 FIG. 5 shows an embodiment of claim 5. By receiving the blade drive cord 14 with the roller 16, the bending of the 14 can be prevented.

図６は請求項６の実施例である。風車あるいは水車が大型の場合、大型スプロケットの製作は容易ではないので、スプロケットの代わりにプーリーのような円盤体をアイドラー１８として使用する。１８と軸１９は回転自由である。なお、１８は全体が回転するか、あるいは大口径ベアリングを１８外周に設置すれば１８全体は回転させなくてもよい。１４の力は小径のスプロケット２０により軸２１の回転に伝達・変換する。この場合、２０は増速器としての機能も持つ。 FIG. 6 shows an embodiment of claim 6. When the windmill or the water turbine is large, it is not easy to manufacture a large sprocket. Therefore, a disk body such as a pulley is used as the idler 18 instead of the sprocket. 18 and shaft 19 are freely rotatable. In addition, 18 does not need to rotate if the whole 18 rotates or if a large diameter bearing is installed in 18 outer periphery. The force 14 is transmitted and converted to the rotation of the shaft 21 by the small-diameter sprocket 20. In this case, 20 also has a function as a speed increaser.

図７は請求項７の実施例である。ブレード２４はサイズの異なる翼が入れ子になっており伸縮任意と成っている。また、風車躯体の軸支柱２５も入れ子になっているので、２４，２５を伸縮することにより受風面積を増減できる。 FIG. 7 shows an embodiment of claim 7. The blades 24 are nested in wings of different sizes and are arbitrarily stretchable. Moreover, since the shaft support | pillar 25 of a windmill housing is also nested, it can increase / decrease a wind receiving area by expanding / contracting 24,25.

図８は請求項８の実施例である。並進翼風車は風向に対しブレード２のピッチ角をそれぞれプラスおよびマイナスに設定することにより回転方向を逆にする事ができる。回転方向が互いに逆である一対の並進翼風車のジャイロモーメントは０となる。 FIG. 8 shows an embodiment of claim 8. The translation blade wind turbine can reverse the rotation direction by setting the pitch angle of the blade 2 to plus and minus with respect to the wind direction. The gyro moment of a pair of translation blade wind turbines whose rotation directions are opposite to each other is zero.

図９は請求項９の実施例である。請求項９を備えた並進翼風車を一モジュールとして使用し、モジュールを多段にタワー１２に回転自由に取り付ける。 FIG. 9 shows an embodiment of claim 9. The translation blade wind turbine provided with claim 9 is used as one module, and the modules are attached to the tower 12 in a freely rotating manner in multiple stages.

図１０は請求項１０の実施例である。風車モジュールをタワー１２に取り付ける場合、回転自由にするためには１２と１０、１１との間にベアリング２２等を介して滑動が容易な方法で取り付ける必要がある。しかしながら、２２で１０、１１の自重を受ける場合には滑動し易さは若干ながらも阻害されるので、自重を非接触な磁気軸受け２３で受けることによりモジュールのタワー周りの滑動が一層容易になる。磁気軸受けは磁石の反発力を利用する。 FIG. 10 shows an embodiment of claim 10. When the wind turbine module is attached to the tower 12, it is necessary to attach the wind turbine module between 12, 10, and 11 via a bearing 22 or the like in a manner that allows easy sliding. However, since the ease of sliding is somewhat obstructed when receiving the own weight of 10, 11 at 22, the sliding around the tower of the module becomes easier by receiving the own weight with the non-contact magnetic bearing 23. . Magnetic bearings use the repulsive force of magnets.

本発明の利用により、並進翼風車の機能性およびエネルギー吸収効率が高まり、従来以上に風力利用の価値が高まる。また風力発電可能な場所が大幅に増えるため、自然エネルギーの活用を促進できる。 By utilizing the present invention, the functionality and energy absorption efficiency of the translational blade wind turbine are increased, and the value of wind power utilization is increased more than before. In addition, since the number of places where wind power can be generated is greatly increased, the use of natural energy can be promoted.
