Description

【0001】
【発明の属する技術分野】
弱い風力でも回転し発電可能な小型の風力発電回転子を複数個集積し、個々の回転力を発電ユニットに集合する風力発電装置に関するものである。
【0002】
【従来の技術】
本出願人は、特開2001−153028で、小型で、弱いトルクしか得られない風にも対応し、エネルギーの有効利用が図れる小型発電装置を提案した。
ここで提案された小型発電装置を再度引用すると、図2のようであり、そのI−Iでの断面図は図3のようになっていた。その詳細な説明は、特開2001−153028に記載されているので省略するが、羽根31を有するヨーク32の内部に円筒状で周方向にS極とN極が交互に形成された永久磁石33が設けられることにより、回転体34の内側が回転磁石になっていて、回転体34の内側には、固定子鉄心に巻かれたコイル35が設けられていて、回転補助手段であるシャフト36の長さが短くでき、増減速機等の付加的装置を介することなく、羽根で受けた風力で直接発電ができ、伝達損失を抑え、弱い風に対しても高効率の発電が可能であった。また、37の部分には、整流回路、電圧安定化回路、充電用の二次電池部等の調整回路があって、その実際の電気回路例は図4のようになっている。
【0003】
図4で、41は、発電コイル部で、L1、L2、L3が図3のコイル35に対応している。42は、D1〜D6のダイオードで脈流を整流する整流回路であり、43は、コンデンサCと抵抗R31〜R33とトランジスタQ31、Q32とツェナーダオードD31からなる定電圧回路である。44は、その出力を充電する二次電池BT1と逆流防止用のダイオードD32と出力端子Th、Tgを有する二次電池部である。ダイオードD32があるので、二次電池BT1からは定電圧回路43側へは、電流が逆流することは無い。但し、D1〜D6のダイオードがあるので、ダイオードD32は、省略が可能である。
【0004】
【発明が解決しようとする課題】
以上のような従来の風力発電の構成では、発電能力を高めるには、羽根の形状を大きくして、風力を集合することが必要であり、広い野外にはよくても、狭い空間に設置するには不都合であり、弱い風でも発電させるには、回転速度の増速装置が必要であった。狭い空間に設置でき、弱い風力でも発電ができる小型の風力発電装置が必要とされた。
【0005】
【課題を解決するための手段】
弱い風力でも回転し発電できる羽根を有する小型の回転子を複数個集積し、ベルト等の回転伝達手段を用いて、永久磁石及び鉄心に巻かれたコイルを有する発電ユニットに回転力を集合するようにしたものである。
請求項1記載の発明は、回転力集合型風力発電装置であって、風力により回転する羽根を有する回転子を複数個集積し、前記回転子の回転を回転伝達手段を用いて、永久磁石及び鉄心に巻かれたコイルを有する発電ユニットに回転力を集合するように構成したことを特徴とする。
【0006】
請求項2記載の発明は、請求項1記載の回転力集合型風力発電装置において、前記の回転伝達手段はベルトであることを特徴とする。
【0007】
【発明の実施の態様】
図1は、本発明に係る風力発電装置の一実施態様を示す図であって、11は、風力を受けて回転する羽根、12は、羽根11の回転とともに回転する回転子であり、回転をベルト等の回転伝達手段14により回転軸15に伝えるようになっている。ベルト等としてVベルト、スプロケット、歯付ベルトが使用できる。
回転子12では、回転を回転伝達手段14に伝えるための歯部を有することを示しているが、必須ではない。16は、発電部収納部であり、図3の32〜36、すなわち、羽根31の部分が無い発電ユニットに対応している。17は、発電された電力を引き出すケーブル部であって、これは、図4の42の整流部に供給される。整流部42が16の内部に収容されている場合は、電圧安定化部43にケーブル17が供給されるというようにどこまで発電部収納部16に収納するかは自由度がある。回転子12の先端の嵌め込み部13と、回転軸15は、支持板18に回転自在にはめ込まれている。発電部収納部16は支持板18に固定されている。発電部の回転体34に対応する部分は、回転軸15に接続されていて回転するというように、発電部収納部16内の動作は図3と同じである。
支持板18は、羽根11を通過する風の通路を塞がないように形成されていることは当然である。
【0008】
【発明の効果】
以上のように、弱い風力でも回転し発電できる羽根を有する小型の回転子を複数個集積し、ベルト等の回転伝達手段を用いて、永久磁石及び鉄心に巻かれたコイルを有する発電ユニットに回転力を集合するようにしたので、弱い風力を効率よく発電ユニットに集合することができ、羽根が大きくならないので、多数集積できて、狭い空間にも設置できる。羽根を有する回転子以外は多数を必要とせず製造コストを削減することもできる。

[Prior art]
The present applicant has proposed, in Japanese Patent Laid-Open No. 2001-153028, a small power generator that can cope with winds that are small and can only obtain a weak torque, and that can effectively use energy.
If the small power generator proposed here is quoted again, it is as shown in FIG. 2, and its sectional view taken along line I-I is as shown in FIG. A detailed description thereof is omitted since it is described in JP-A-2001-153028, but a permanent magnet 33 in which a S pole and a N pole are alternately formed in the circumferential direction in a cylindrical shape inside a yoke 32 having blades 31. Is provided, the inner side of the rotating body 34 is a rotating magnet, and the inner side of the rotating body 34 is provided with a coil 35 wound around a stator iron core. The length can be shortened and power can be generated directly with the wind force received by the blades without using additional devices such as speed reducers, suppressing transmission loss and enabling high-efficiency power generation even with weak winds. . Further, in the portion 37, there are adjustment circuits such as a rectifier circuit, a voltage stabilization circuit, and a secondary battery part for charging, and an actual electric circuit example is as shown in FIG.
[0003]
In FIG. 4, 41 is a power generation coil section, and L1, L2, and L3 correspond to the coil 35 of FIG. Reference numeral 42 denotes a rectifier circuit that rectifies the pulsating current with the diodes D1 to D6. Reference numeral 43 denotes a constant voltage circuit including a capacitor C, resistors R31 to R33, transistors Q31 and Q32, and a zener diode D31. Reference numeral 44 denotes a secondary battery unit having a secondary battery BT1 for charging its output, a backflow prevention diode D32, and output terminals Th and Tg. Since there is the diode D32, current does not flow backward from the secondary battery BT1 to the constant voltage circuit 43 side. However, since there are diodes D1 to D6, the diode D32 can be omitted.
[0004]
[Problems to be solved by the invention]
In the conventional wind power generation configuration as described above, in order to increase the power generation capacity, it is necessary to increase the shape of the blades and collect the wind power. In order to generate power even in a weak wind, a speed increasing device was required. There was a need for a small wind power generator that could be installed in a small space and could generate electricity even with weak wind power.
[0005]
[Means for Solving the Problems]
A plurality of small rotors having blades that can rotate and generate electric power even with weak wind power are integrated, and rotational force is collected in a power generation unit having a coil wound around a permanent magnet and an iron core by using a rotation transmission means such as a belt. It is a thing.
The invention according to claim 1 is a rotational force collective wind power generator, wherein a plurality of rotors having blades rotated by wind force are integrated, and the rotation of the rotor is transmitted using rotation transmission means, and a permanent magnet and The power generation unit having a coil wound around an iron core is configured to collect rotational force.
[0006]
According to a second aspect of the present invention, in the rotational force collective wind power generator according to the first aspect, the rotation transmission means is a belt.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 is a diagram showing an embodiment of a wind power generator according to the present invention, in which 11 is a blade that rotates by receiving wind force, and 12 is a rotor that rotates together with the rotation of the blade 11. The rotation is transmitted to the rotation shaft 15 by a rotation transmission means 14 such as a belt. A V belt, sprocket, or toothed belt can be used as the belt.
Although the rotor 12 has a tooth portion for transmitting the rotation to the rotation transmitting means 14, it is not essential. Reference numeral 16 denotes a power generation unit storage unit, which corresponds to the power generation unit 32 to 36 in FIG. Reference numeral 17 denotes a cable unit for drawing out the generated electric power, which is supplied to the rectifying unit 42 in FIG. When the rectifying unit 42 is accommodated in the interior 16, there is a degree of freedom in how far the power generating unit accommodating unit 16 accommodates the cable 17 to be supplied to the voltage stabilizing unit 43. The fitting portion 13 at the tip of the rotor 12 and the rotating shaft 15 are rotatably fitted to the support plate 18. The power generation unit storage unit 16 is fixed to the support plate 18. The portion of the power generation unit corresponding to the rotating body 34 is connected to the rotation shaft 15 and rotates, so that the operation in the power generation unit storage unit 16 is the same as that in FIG.
Naturally, the support plate 18 is formed so as not to block the passage of the wind passing through the blades 11.
[0008]
【The invention's effect】
As described above, a plurality of small rotors having blades that can rotate and generate electric power even with weak wind power are integrated and rotated to a power generation unit having a coil wound around a permanent magnet and an iron core using a rotation transmission means such as a belt. Since the power is gathered, weak wind power can be gathered efficiently in the power generation unit, and since the blades do not become large, many can be integrated and installed in a narrow space. Other than the rotor having blades, a large number is not required, and the manufacturing cost can be reduced.
