Abstract

<P>PROBLEM TO BE SOLVED: To solve problems with a conventional wind power generation device wherein a rotor is broken because only the rotating shaft or its vicinity of the rotor, namely, only the root or the bearing of the rotor receives wind pressure on the rotor, and a heavy generator is installed at a high place near the rotating shaft. <P>SOLUTION: This wind power generation device can distribute wind pressure on a rotor 2 into a rotating shaft and a circular fixed frame 1 and transmit the power of a circular rotary part via a gear to a generator, while the generator can be installed at the lower part of the device, not at a high place. Thereby, it is hard to destroy and capable of being larger. A wind turbine can be installed on the sea while using a shaft-type anchoring device on the float side for mounting a vertical blade thereon. Thus, it always catches wind from its front face. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

本発明は、風圧を回転軸及び円形固定枠に分散させる風力発電装置。

本発明の風力発電装置を海上等に設置する際、風力発電本体を設置する浮体が回転し風車が風を正面から受けることができるようにした浮体。The present invention is a wind turbine generator that distributes wind pressure to a rotating shaft and a circular fixed frame.
A wind turbine generator that can be installed in the lower part of the wind turbine generator.
A floating body in which when the wind power generator of the present invention is installed on the sea or the like, the floating body on which the wind power generation main body is installed rotates so that the windmill can receive wind from the front.

従来の風力発電装置は、回転翼を回転軸付近のみ、つまり回転翼の付け根のみで回転翼にかかる風圧を受けていた。
また、発電機は、回転軸付近の高所に設置していた。In the conventional wind power generator, the rotor blade is subjected to wind pressure applied to the rotor blade only at the vicinity of the rotating shaft, that is, only at the root of the rotor blade.
The generator was installed at a high place near the rotating shaft.

以上に述べた従来の風力発電装置では、回転翼を回転軸付近のみ、つまり回転翼の付け根のみで回転翼にかかる風圧を受けていたため台風等の強風下では回転翼が折れたり支柱が折れたりした。
また、重量のある発電機を支柱の上である高所に設置していた。In the conventional wind power generators described above, the rotor blades were subjected to wind pressure applied to the rotor blades only near the rotating shaft, that is, only at the roots of the rotor blades. did.
In addition, a heavy generator was installed at a high place on the column.

本発明は、このような従来の構造が有していた問題を解決しようとするものであり、台風などの強風下でも回転翼が折れず、支柱も倒壊せず、発電機も下部に設置可能であり、より大型化できる風力発電装置を実現することを目的とするものである。
また、同上の風力発電装置を海上等に設置するさい風車が風を正面から受けることができる浮体の実現を目的とするものである。The present invention is intended to solve the problems of such a conventional structure, and the rotor blades do not break even under strong winds such as typhoons, the props do not collapse, and the generator can be installed in the lower part. Therefore, an object of the present invention is to realize a wind turbine generator that can be further increased in size.
Another object of the present invention is to realize a floating body that can receive wind from the front when a wind turbine in which the wind power generator is installed on the sea or the like.

本発明は、上記目的を達成するため回転翼にかかる風圧を回転軸及び円形固定枠に分散させ、円形回転部分の動力をギャ等で発電機に伝達することが可能で発電機を高所ではなく装置下部に設置することもでき、本発明角の風車を海上に設置する際、風を正面から受けることができるようするため浮体側の係留装置を軸型にして垂直翼つける。  In order to achieve the above object, the present invention can disperse the wind pressure applied to the rotor blades to the rotating shaft and the circular fixed frame, and transmit the power of the circular rotating part to the generator by gears or the like. It can also be installed at the lower part of the device, and when installing the windmill of the present invention angle on the sea, the mooring device on the floating body side is attached to the vertical type to attach the vertical wing so that the wind can be received from the front.
