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 wind power generator 1 includes a support housing 10 installed on an installation surface S, a power generator 11 and a gearbox 12 arranged inside the support housing 10, and a gearbox 12. and a rotating portion 13 having a first rotating shaft O1 perpendicular to the installation surface S, and a second rotating shaft O2 parallel to the first rotating shaft O1. Three cylindrical blades 2 that can rotate around the center, and a circumference C around the first rotation axis O1 that can rotate around the first rotation axis O1 by being fixed to the rotating part 13 and a support portion 3 that pivotally supports each of the three cylindrical blades 2 thereon.

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 protrudes the upper end 130 of the rotating section 13 from the upper surface 100 of the supporting housing 10, and rotates the rotating section 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 portion 13 via the gearbox 12, and is configured to generate electric power by converting rotational energy generated when the rotating portion 13 rotates into electrical 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 equidistantly spaced on a circumference C around the first rotation axis O1 when the vertical axis type Magnus wind power generator 1 is viewed from above. , that is, at each vertex of an 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。 In addition, each of the three cylindrical blades 2 has a cylindrical blade motor 20 that rotates (rotates) the cylindrical blades 2 clockwise around the second rotation axis O2, and a motor 20 that is spaced apart from the cylindrical blades 2 by a predetermined distance. , and a current plate 5 arranged parallel to 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 wind power generator 1 rotates (rotates) the cylindrical blades 2 clockwise around the second rotation axis O2 by the cylindrical blade motor 20, and generates wind (air flow) from a predetermined direction. , a Magnus force is generated in the cylindrical blade 2 . Then, the Magnus force generated in the cylindrical blades 2 acts in a direction to move the cylindrical blades 2 along the circumference C clockwise. As a result, the rotating portion 13 rotates clockwise, so that the generator 11 connected to the rotating portion 13 generates power.

垂直軸型マグナス式風力発電機１の円筒翼２は、回転部１３の第１の回転軸Ｏ１を中心として等距離及び等角度に配置される。本実施形態の垂直軸型マグナス式風力発電機１は、３つの円筒翼２を設けるので、１２０°離間して配置される。 The cylindrical blades 2 of the vertical axis type Magnus wind power generator 1 are arranged at equal distances and angles around the first rotation axis O1 of the rotating part 13 . Since the vertical axis type Magnus wind power generator 1 of this embodiment is provided with three cylindrical blades 2, they are arranged at intervals of 120°.

図４に示す垂直軸型マグナス式風力発電機１の円筒翼２は、それぞれの第２の回転軸Ｏ２を中心として矢印Ａのように時計方向に回転可能である。気流中で各円筒翼２を回転させることで、各円筒翼２にマグナス力が発生し、図３に示した支持部３及び回転部１３が第１の回転軸Ｏ１を中心として矢印Ｂのように時計方向に回転する。すなわち、円筒翼２は、第２の回転軸Ｏ２を中心として自転し、第１の回転軸Ｏ１を中心として公転する。 The cylindrical blades 2 of the vertical axis type Magnus wind power generator 1 shown in FIG. By rotating each cylindrical blade 2 in the airflow, a Magnus force is generated in each cylindrical blade 2, and the supporting portion 3 and rotating portion 13 shown in FIG. to rotate clockwise. That is, the cylindrical blade 2 rotates around the second rotation axis O2 and revolves around the first rotation axis O1.

図５は、本発明の第１の実施形態に係るマグナス式推力発生装置の翼端板６を示す。 FIG. 5 shows the wing end plate 6 of the Magnus thrust generator according to the first embodiment of the present invention.

翼端板６は、上方から見て整流板５の第１表面５１及び第２表面５２から水平方向に突出するように設置される。なお、第１表面５１は第１縁５１ａと後端縁５ａを結ぶ整流板５の表面であり、第２表面５２は第２縁５２ａと後端縁５ａを結ぶ整流板５の表面である。 The blade end plate 6 is installed so as to horizontally protrude from the first surface 51 and the second surface 52 of the current plate 5 when viewed from above. The first surface 51 is the surface of the current plate 5 that connects the first edge 51a and the rear edge 5a, and the second surface 52 is the surface of the current plate 5 that connects the second edge 52a and the rear edge 5a.

このように、翼端板６を設けることによって、翼表面を流れる空気の流れと翼周辺を流れる空気の流れを仕切り、気流の乱れを抑制することによって、効率を向上させることができる。 Thus, by providing the blade end plate 6, it is possible to separate the flow of air flowing on the surface of the blade from the flow of air flowing around the blade, thereby suppressing the turbulence of the air flow and improving the efficiency.
