FIG. 2 is a schematic front view showing a schematic configuration of the vertical axis type Magnus-type wind power generator 1 according to the first embodiment of the present invention. FIG. 3 is a schematic plan view showing a schematic configuration of the vertical axis Magnus-type wind power generator 1 according to the first embodiment of the present invention.

垂直軸型マグナス式風力発電機１は、設置面Ｓに対して設置される支持筐体１０と、支持筐体１０の内部に配置される発電機１１及び増速機１２と、増速機１２を介して発電機１１に連結されるとともに、設置面Ｓに対して垂直な第１の回転軸Ｏ１を有する回転部１３と、第１の回転軸Ｏ１に対して平行な第２の回転軸Ｏ２を中心として自転可能な３つの円筒翼２と、回転部１３に固定されることで第１の回転軸Ｏ１を中心として回転可能であって、第１の回転軸Ｏ１を中心とする円周Ｃ上に３つの円筒翼２の各々を軸支する支持部３と、を備える。 The vertical axis type Magnus-type wind power generator 1 includes a support housing 10 installed on the installation surface S, a generator 11 and a gearbox 12 disposed inside the support housing 10, and a gearbox 12. And a rotating part 13 having a first rotating axis O1 perpendicular to the installation surface S and a second rotating axis O2 parallel to the first rotating axis O1. And a circular cylinder C that is rotatable about a first rotation axis O1 by being fixed to the rotating part 13 and is rotatable about the first rotation axis O1. And a support portion 3 for supporting each of the three cylindrical blades 2 above.

支持筐体１０は、第１の回転軸Ｏ１と同軸状に配置される円筒状の筐体である。支持筐体１０は、支持筐体１０の上面１００から回転部１３の上端部１３０を突出させるとともに、第１の回転軸Ｏ１が設置面Ｓに対して垂直となるように、回転部１３を軸支する。 The support housing 10 is a cylindrical housing arranged coaxially with the first rotation axis O1. The support housing 10 projects the upper end portion 130 of the rotation unit 13 from the upper surface 100 of the support housing 10 and pivots the rotation unit 13 so that the first rotation axis O1 is perpendicular to the installation surface S. Support.

発電機１１は、増速機１２を介して回転部１３に連結されており、回転部１３が回転する際の回転エネルギーを電気エネルギーに変換することで発電するように構成されている。 The generator 11 is connected to the rotating unit 13 via the gearbox 12 and is configured to generate electric power by converting rotational energy when the rotating unit 13 rotates into electric energy.

３つの円筒翼２は、図３に示すように、垂直軸型マグナス式風力発電機１を上方から見たときに、第１の回転軸Ｏ１を中心した円周Ｃ上で等間隔となるように、すなわち、正三角形の各頂点に配置される。 As shown in FIG. 3, the three cylindrical blades 2 are arranged at equal intervals on a circumference C around the first rotation axis O1 when the vertical axis type Magnus type wind power generator 1 is viewed from above. , Ie, at each vertex of the equilateral triangle.

また、３つの円筒翼２の各々は、第２の回転軸Ｏ２を中心として円筒翼２を時計回りに回転（自転）させる円筒翼モーター２０と、円筒翼２から所定の距離だけ離間した位置に、第２の回転軸Ｏ２に対して平行となるように配置される整流板５と、を備える。 Further, each of the three cylindrical blades 2 is located at a position separated by a predetermined distance from the cylindrical blade motor 20 for rotating (rotating) the cylindrical blade 2 clockwise about the second rotation axis O2.

垂直軸型マグナス式風力発電機１は、円筒翼モーター２０により第２の回転軸Ｏ２を中心として円筒翼２を時計回りに回転（自転）させた状態において、所定の方向から風（空気流）を受けると、円筒翼２にマグナス力が発生する。そして、円筒翼２に発生したマグナス力が、円筒翼２を円周Ｃに沿って時計回りに移動させる方向に作用する。それにより、回転部１３が時計回りに回転することで、回転部１３に連結された発電機１１で発電する。 The vertical axis type Magnus type wind power generator 1 winds (airflow) from a predetermined direction in a state where the cylindrical blade 2 is rotated clockwise (rotated) about the second rotation axis O2 by the cylindrical blade motor 20. Then, a Magnus force is generated in the cylindrical wing 2.
