Description
本発明は、高温超電導体により浮上させた円筒型風力発電機に関するものである。 The present invention relates to a cylindrical wind power generator levitated by a high-temperature superconductor.
現在開発されている超電導フライホイールは装置全体を真空にしている。また、フライホイールはコマ型である。このためオイラーの運動方程式により、回転軸のぶれが起こり易い。更に、従来の装置は大型で構造が複雑であるといった問題があった。 The superconducting flywheel currently being developed places the entire device in a vacuum. The flywheel is a top type. For this reason, the rotation axis is likely to be shaken by the Euler equation of motion. Further, the conventional apparatus has a problem that it is large and complicated in structure.
また、鉛直状の回転体を制御型ラジアル磁気軸受と、制御型アキシャル磁気軸受で安定回転位置に支持した状態で、超電導体を冷却して超電導軸受を作動状態にし、超電導軸受とラジアル磁気軸受で回転体を安定回転位置に支持し、回転体を回転させて運転を開始するようにした超電導軸受装置が提案されている（下記特許文献１参照）。

すなわち、
〔Ａ〕円筒形羽根車を、冷却以前の高温超電導体（イットリウム系、ガドリニウム系、サマリウム系、ネオジウム系などの臨界温度が液体窒素以上であること）との間にギャップを持たせた後、高温超電導体を冷却し、円筒形羽根車を浮上させ、円筒形羽根車の上部には極を交互に一列に配置された発電用磁石を設け、その発電用磁石を回転させ、一定の回転力を与えた後は円筒形羽根車の惰性（完全真空中なら慣性）で回転させ、前記発電用磁石の外部に固定された発電用コイルにより発電する。主に家庭用自己発電程度としてのものであるが、システム全体あるいは部分的に大型システムとしてもよい。
That is,
[A] After making a gap between the cylindrical impeller and the high-temperature superconductor before cooling (the critical temperature of yttrium, gadolinium, samarium, neodymium, etc. is higher than liquid nitrogen), The high-temperature superconductor is cooled, the cylindrical impeller is levitated, and a power generation magnet with alternating poles arranged in a row is provided at the top of the cylindrical impeller. Then, the power is rotated by the inertia of the cylindrical impeller (inertia in a complete vacuum), and power is generated by the power generating coil fixed outside the power generating magnet. Although it is mainly intended for home self-power generation, the entire system or a part of the system may be a large system.
〔Ｂ〕円筒形羽根車の径が円形状の高温超電導体の径と同じか小さいことにより、ピンニング作用で安定した回転運動を得ることができる。円筒形羽根車は、導体あるいは絶縁体のどちらでも良いが下部浮上用磁石と発電用磁石の磁力の関係を配慮する必要がある。回転体内部は空洞でもよい。ただし、回転慣性は自重に比例するので、浮上力と目標回転数を考慮する必要がある。 [B] Since the diameter of the cylindrical impeller is equal to or smaller than the diameter of the circular high-temperature superconductor, a stable rotational motion can be obtained by a pinning action. The cylindrical impeller may be either a conductor or an insulator, but it is necessary to consider the relationship between the magnetic force of the lower levitation magnet and the power generation magnet. The inside of the rotating body may be a cavity. However, since the rotational inertia is proportional to its own weight, it is necessary to consider the levitation force and the target rotational speed.
〔Ｃ〕円形状の浮上用磁石と冷却以前の円形状の高温超電導体との間にギャップを持たせる方法は、発電用磁石の配列した磁石配列と対になる配列の磁石により磁力吸引し、発電用磁石を持ち上げるか、または、機械的に持ち上げる機構を設置してもよい。 [C] A method of providing a gap between the circular levitation magnet and the circular high-temperature superconductor before cooling includes attracting magnetic force by a magnet in a pair with a magnet arrangement in which power generation magnets are arranged, A mechanism for lifting the power generation magnet or mechanically lifting it may be installed.
〔Ｄ〕発電用コイルは複数を円周上に配置してもよい。発電用コイルを浮上用高温超電導体の冷却システムの寒剤蒸気あるいは冷却空気により冷却しても良い。発電用コイルを高温超電導線材（現在ではイットリウム系）としてもよい。この場合、冷却は浮上用高温超電導体の冷却システムを利用できる。コイル系を高温超電導線材を用いることにより、抵抗ロスと発熱をほぼなくすことができる。 [D] A plurality of power generating coils may be arranged on the circumference. The coil for power generation may be cooled by cryogen vapor or cooling air of a cooling system for a high temperature superconductor for levitation. The power generation coil may be a high-temperature superconducting wire (currently yttrium-based). In this case, cooling can use a cooling system for a high temperature superconductor for levitation. By using a high-temperature superconducting wire for the coil system, resistance loss and heat generation can be almost eliminated.
〔Ｅ〕円筒形羽根車の惰性回転は夜間時間（１６時間）回転していれば、日中の外部供給電源をソーラー発電に依存して、外部供給電源費用をなくすことができる。風力とのハイブリッド発電も用いれば、回転体の回転を風力発電で補助しつつ、高速一定に維持することも可能である。 [E] If the inertial rotation of the cylindrical impeller rotates at night time (16 hours), the external power supply cost can be eliminated by relying on solar power for daytime external power supply. If hybrid power generation with wind power is also used, it is possible to keep the rotating body constant at high speed while assisting the rotation of the rotating body with wind power generation.
〔Ｆ〕磁界漏れの発生を防ぎたい場合には、システムが小型であるのでシステム全体をシールドすればよい。 [F] If it is desired to prevent the occurrence of magnetic field leakage, the entire system may be shielded because the system is small.
〔Ｇ〕発電用磁石は、円筒形羽根車の上部に配置する場合には回転体の遠心力による回転体からの離脱、内側に配置する場合には磁石相互の吸引力による回転体からの離脱を防止するための外枠（円筒）あるいは内枠（円筒）が必要となる。 [G] When the magnet for power generation is arranged at the upper part of the cylindrical impeller, it is detached from the rotating body by the centrifugal force of the rotating body, and when it is arranged inside, it is detached from the rotating body by the mutual attractive force of the magnets. Therefore, an outer frame (cylinder) or an inner frame (cylinder) is required to prevent this.
本発明によれば、次のような効果を奏することができる。 According to the present invention, the following effects can be achieved.
（１）簡素な構成でエネルギーの損失を低減できる円筒型風力発電機を提供することができる。 (1) A cylindrical wind power generator capable of reducing energy loss with a simple configuration can be provided.
（２）羽根を円筒形回転体とすることにより、ｘ、ｙ、ｚの主慣性モーメントを等しい方向に近づけることができ、いわゆる球こまに近い安定性を得ることができる。 (2) By making the blade into a cylindrical rotating body, the main moments of inertia of x, y, and z can be made to approach in the same direction, and so-called spherical top stability can be obtained.
本発明の高温超電導体により浮上させた円筒型風力発電機は、円形状の浮上用磁石と、この円形状の浮上用磁石の上部に固定され、この円形状の浮上用磁石に垂直な方向に軸を有する円筒形羽根車と、この円筒形羽根車の上部に交互に極が一列に配置された発電用磁石と、この発電用磁石に対向して配置される発電用コイルと、前記円形状の浮上用磁石とギャップを有して対向する円形状の浮上用高温超電導体（イットリウム系、ガドリニウム系、サマリウム系、ネオジウム系などの臨界温度が液体窒素以上であること）とを具備し、前記円形状の浮上用磁石を有する円筒形羽根車を、冷却以前の前記浮上用高温超電導体との間にギャップを持たせた後、前記浮上用高温超電導体を冷却し、前記円筒形羽根車を浮上させ、前記円筒形羽根車に一定の回転力を与えた後は前記円筒形羽根車の惰性で回転させ、前記発電用磁石の回転により、前記発電用コイルで発電する。 The cylindrical wind power generator levitated by the high-temperature superconductor of the present invention is fixed to a circular levitation magnet and an upper portion of the circular levitation magnet, and in a direction perpendicular to the circular levitation magnet. A cylindrical impeller having a shaft, a power generating magnet in which poles are alternately arranged in a row on the top of the cylindrical impeller, a power generating coil disposed to face the power generating magnet, and the circular shape A high-temperature superconductor for levitation that is opposed to the levitation magnet with a gap (the critical temperature of yttrium-based, gadolinium-based, samarium-based, neodymium-based, etc. is liquid nitrogen or higher), and A cylindrical impeller having a circular levitation magnet is provided with a gap between the levitation high-temperature superconductor before cooling, the levitation high-temperature superconductor is cooled, and the cylindrical impeller is Levitated to the cylindrical impeller After giving a constant rotational force rotates by inertia of the cylindrical impeller, the rotation of the generator magnet and the power generation by the power generating coil.
以下、本発明の実施の形態について詳細に説明する。 Hereinafter, embodiments of the present invention will be described in detail.
図１は本発明の第１実施例を示す高温超電導体により浮上させた円筒型風力発電機の模式図である。 FIG. 1 is a schematic view of a cylindrical wind power generator levitated by a high-temperature superconductor according to a first embodiment of the present invention.
この図において、１は円形状の浮上用磁石、２はその浮上用磁石１の上部に固定され、かつ風力Ｆの方向に垂直な方向に軸を有する円筒形羽根車、３はその円筒形羽根車２の上部に配置される極を交互に一列に配置された発電用磁石である。その円形状の円形状の浮上用磁石１の下部に対向配置される円形状の浮上用高温超電導体４と、発電用磁石３に対向する位置に配置される発電用コイル９とを具備し、円形状の浮上用磁石１を、冷却以前の円形状の浮上用高温超電導体４との間にギャップを持たせた後、円形状の浮上用高温超電導体４を冷却し、円形状の浮上用磁石１を浮上させ、発電用磁石３を回転させ、円筒形羽根車２に一定の回転力を与えた後は円筒形羽根車２の惰性で回転させ、発電用磁石３の回転により、発電用磁石３の外部に設置した発電用コイル９で発電する。なお、５は冷却容器、６はその冷却容器５に充填される液体窒素あるいは液体窒素蒸気の導入管、７はその冷却容器５からの蒸発ガスの導出管、８は断熱層、１０発電用コイル９から発電される電力の測定装置である。 In this figure, 1 is a circular levitation magnet, 2 is a cylindrical impeller fixed to the top of the levitation magnet 1, and has an axis in a direction perpendicular to the direction of wind force F, 3 is its cylindrical blade It is a magnet for power generation in which poles arranged at the top of the vehicle 2 are alternately arranged in a line. A circular levitation high-temperature superconductor 4 disposed opposite to the lower portion of the circular levitation magnet 1, and a power generation coil 9 disposed at a position facing the power generation magnet 3. After providing a gap between the circular levitation magnet 1 and the circular levitation high-temperature superconductor 4 before cooling, the circular levitation high-temperature superconductor 4 is cooled to obtain a circular levitation The magnet 1 is levitated, the power generation magnet 3 is rotated, and after giving a certain rotational force to the cylindrical impeller 2, it is rotated by the inertia of the cylindrical impeller 2. Power is generated by a power generation coil 9 installed outside the magnet 3. In addition, 5 is a cooling container, 6 is an introduction pipe for liquid nitrogen or liquid nitrogen vapor filled in the cooling container 5, 7 is a lead-out pipe for evaporating gas from the cooling container 5, 8 is a heat insulating layer, 10 a coil for power generation 9 is a measuring device for the electric power generated from 9.
この図において、円筒形羽根車２と円形状の浮上用磁石１とは完全に固定されている。また、円筒形羽根車２と発電用磁石３も完全に固定されている。 In this figure, the cylindrical impeller 2 and the circular levitation magnet 1 are completely fixed. The cylindrical impeller 2 and the power generation magnet 3 are also completely fixed.
また、円筒形羽根車２の径は円形状の浮上用高温超電導体４の径とほぼ同じか若干小さくすることにより、ピンニング作用で安定した回転運動を得るように構成することが望ましい。 Further, it is desirable that the diameter of the cylindrical impeller 2 is approximately the same as or slightly smaller than the diameter of the circular levitation high-temperature superconductor 4 so as to obtain a stable rotational motion by a pinning action.
円筒形羽根車２の浮上は、円形状の浮上用磁石１と円形状の浮上用高温超電導体４の間にギャップを持たせた後、円形状の浮上用高温超電導体４を冷却した後、ギャップを取り去ることにより得ることができる。 The floating of the cylindrical impeller 2 is performed by providing a gap between the circular levitation magnet 1 and the circular levitation high-temperature superconductor 4 and then cooling the circular levitation high-temperature superconductor 4. It can be obtained by removing the gap.
ギャップを持たせる方法は、機械的でも、後述するように上部からの磁石による磁力によってもよい。 The method for providing the gap may be mechanical or may be a magnetic force from a magnet from above as described later.
羽根車の形状は円筒形でよい。超電導体のピンニング作用を利用するので、ＳＭＥＳのようなコマ型よりも安定する。円筒形羽根車の寸法は、浮上用磁石と発電用磁石との影響がないようにし、かつ安定な回転を得られるようにするには、直径と高さの比は１：１程度が望ましい。ただし、装置を小型にする場合には高さの比が直径を上回っても、ピンニング力が勝るならば安定した回転を得ることができる。 The shape of the impeller may be cylindrical. Since the pinning action of the superconductor is used, it is more stable than the coma type like SMES. As for the dimensions of the cylindrical impeller, the ratio of the diameter and the height is preferably about 1: 1 in order to avoid the influence of the levitation magnet and the power generation magnet and to obtain a stable rotation. However, when the device is downsized, even if the height ratio exceeds the diameter, stable rotation can be obtained if the pinning force is superior.
円筒形羽根車の初期の回転は羽根への風の吹きつけにより行うことができる。 The initial rotation of the cylindrical impeller can be performed by blowing wind onto the blades.
図２は本発明の第２実施例を示す高温超電導体により浮上させた円筒型風力発電機の上面図である。 FIG. 2 is a top view of a cylindrical wind power generator levitated by a high temperature superconductor according to a second embodiment of the present invention.

A coil 19 is a measuring device for the electric power output from the power generating coils 15-18. An impeller (not shown) is disposed below the power generation coil support plate 14.

この図において、２１は発電用磁石、２２は発電用磁石２１が固定される円筒形羽根車、２３は円筒形羽根車２２の下部に固定される円形状の浮上用磁石、２４は発電用磁石２１の極と対応する極を有する円筒形羽根車２２を持ち上げるための扛重用磁石であり、この扛重用磁石２４の持ち上げにより、円形状の浮上用磁石２３と浮上用高温超電導体（図示なし）との間にギャップを持たせることができる。 In this figure, 21 is a power generating magnet, 22 is a cylindrical impeller to which the power generating magnet 21 is fixed, 23 is a circular levitation magnet fixed to the lower part of the cylindrical impeller 22, and 24 is a power generating magnet. This is a hoisting magnet for lifting a cylindrical impeller 22 having poles corresponding to 21 poles. By lifting this hoisting magnet 24, a circular levitation magnet 23 and a levitation high-temperature superconductor (not shown) There can be a gap between them.
なお、このような磁気力により持ち上げ機構に限定されるものではなく、機械的な持ち上げ機構によってギャップを持たせるようにすることもできる。 Note that the magnetic force is not limited to the lifting mechanism, and a gap may be provided by a mechanical lifting mechanism.
このようにして、発電用磁石２１の側面に配列した磁石配列と対になる配列の扛重用磁石２４により磁力吸引し、円筒形羽根車２２を持ち上げることにより、円形状の浮上用磁石２３と円形状の浮上用高温超電導体（図示なし）との間にギャップを持たせることができる。 In this way, by attracting the magnetic force with the magnet 24 for the counterweight arranged in a pair with the magnet arrangement arranged on the side surface of the power generation magnet 21 and lifting the cylindrical impeller 22, the circular levitation magnet 23 and the circular A gap can be provided between the floating high-temperature superconductor (not shown).
また、円筒形羽根車２２中に機械的に持ち上げる機構を設置するようにしてもよい。 Further, a mechanical lifting mechanism may be installed in the cylindrical impeller 22.
そして、円筒形羽根車２２の浮上は、円形状の浮上用磁石２３と浮上用超電導体の間にギャップを持たせた後、浮上用超電導体を冷却した後、ギャップを取り去ることにより得る。 The floating of the cylindrical impeller 22 is obtained by providing a gap between the circular levitation magnet 23 and the levitation superconductor, cooling the levitation superconductor, and then removing the gap.

この図において、発電用コイル９を浮上用高温超電導体の冷却システム３１の寒剤蒸気あるいは冷却空気により冷却するようにした。 In this figure, the power generating coil 9 is cooled by the cryogen vapor or the cooling air of the cooling system 31 for the high temperature superconductor for levitation.
更に、発電用コイル９を高温超電導線材３２とするように構成する。 Further, the power generating coil 9 is configured to be a high temperature superconducting wire 32.
このように、構成することにより、発電用コイルでの電力損失を大幅に低減し、電力の高出力化を図ることができる。 By configuring in this way, it is possible to significantly reduce the power loss in the power generating coil and increase the power output.
上記したように、風力による円筒形羽根車の回転により、円筒形羽根車と一体化されている発電用磁石も回転し、この発電用磁石の回転により、固定されている発電用コイルで発電を行うことができる。そのようにして得られた発電電力の変動は、円筒形羽根車の回転に応じて発電出力の一部を充放電するフライホイール装置の回転を制御する（上記特許文献２参照）などの手だてを施すことにより安定化させることができる。 As described above, the power generation magnet integrated with the cylindrical impeller is also rotated by the rotation of the cylindrical impeller by wind power, and the rotation of the power generation magnet generates power with the fixed power generation coil. It can be carried out. The fluctuation of the generated power thus obtained is a measure such as controlling the rotation of the flywheel device that charges and discharges part of the generated output according to the rotation of the cylindrical impeller (see Patent Document 2). It can be stabilized by applying.
