　近年、環境に対する意識の高まりから、風力発電装置が注目を集めている。小型の風力発電装置は、風のある場所であれば、基本的にどこでも設置することができる。風力発電装置は、電力需要の多いビル等の建物において、共有部分の照明等の付帯設備に電力を供給する役割や、停電等の際に補完的に電力を供給する役割を担う設備として設置され、活用されることが期待されている。風力発電装置は、例えば、ビル等の建物の周囲や屋上等に設置される。このような風力発電装置に用いられる装置の一例として、特許文献１には集風型風車が開示されている。 In recent years, wind power generators have attracted attention due to the growing awareness of the environment. A small wind power generator can be installed basically anywhere where there is wind. A wind turbine generator is installed as a facility that plays a role of supplying power to ancillary facilities such as lighting in a common area in buildings where there is a large demand for electric power, or supplementary power in the event of a power failure, etc. , Is expected to be utilized. The wind power generator is installed, for example, around a building such as a building or on a rooftop. As an example of an apparatus used for such a wind power generator, Patent Document 1 discloses a wind collecting wind turbine.
　特許文献１に開示された集風型風車は、前方風胴体と、風車が内部に設置されている中間風胴体と、後方風胴体とから一体的に構成されている。前記前方風胴体は、風流入口を有し、かつその横断面積が前記風流入口から前記中間風胴体との接続部分までの間で縮小するように構成されており、前記中間風胴体は、前記前方風胴体の縮小した横断面積が、前記後方風胴体との接続部分までの間で拡大するか又は同じ横断面積を保持するように構成されている。そして前記後方風胴体は、風流出口を有し、かつその横断面積が前記中間風胴体との接続部分から前記風流出口までの間で拡大するように構成されている。 The wind-collecting wind turbine disclosed in Patent Document 1 is integrally formed of a front wind tunnel, an intermediate wind tunnel in which the wind turbine is installed, and a rear wind tunnel.

　ところで、前記従来の集風型風車は、風を集めて風車が回転するように構成されているものであるが、風車が回転する風向きは特定の風向きに限定されている。このため、風向きによっては風車の回転速度が低く、風車を効率的に回転させることができないという課題があった。 By the way, the conventional wind-collecting type windmill is configured to collect wind and rotate the windmill, but the wind direction in which the windmill rotates is limited to a specific wind direction. For this reason, the rotation speed of the windmill was low depending on the wind direction, and there was a problem that the windmill could not be rotated efficiently.
　本発明は前記事情に鑑みてなされたもので、風向きがいずれの方向であっても回転部材を効率的に回転させることができる集風装置、およびこの集風装置を備えた風力回転装置または風力発電装置を提供することを目的とする。 The present invention has been made in view of the above circumstances, and a wind collecting device capable of efficiently rotating a rotating member regardless of the wind direction, and a wind rotating device or wind power provided with the wind collecting device. An object is to provide a power generator.
　前記目的を達成するために、本発明に係る集風装置は、円形状を有する回転部材を収納するための収容部が内側に設けられ、前記回転部材と同軸に形成された環状の集風装置であって、径方向外側に設けられた取込口から風を取り込むとともに、径方向内側に設けられた排出口から前記収容部に風を排出する集風部を備え、前記集風部は、周方向に沿って複数形成されており、隣り合う前記集風部の間を仕切る仕切り板の方向が、前記回転部材の接線方向となっていることを特徴とする。 In order to achieve the above-mentioned object, an air collecting device according to the present invention is an annular air collecting device provided with an accommodating portion for accommodating a rotating member having a circular shape inside and formed coaxially with the rotating member. Then, while taking in the wind from the intake port provided on the radially outer side, and equipped with a wind collecting unit for discharging the wind from the discharge port provided on the radially inner side to the housing portion, It is formed in multiple numbers along the circumferential direction, The direction of the partition plate which partitions off between the said adjacent wind collection parts is a tangent direction of the said rotation member, It is characterized by the above-mentioned.
　このような構成によれば、周方向に沿って複数形成された集風部を備えているため、風向きがいずれの方向であっても、風を集めることができる。これにより、風向きに左右されず風を集め、回転部材を回転させることができる。
　また、本発明に係る集風装置では、隣り合う集風部の間を仕切る仕切り板の方向が、回転部材の接線方向となっている。このため、集めた風を最も効率的に回転部材の回転に利用することができる。これにより、風が微風の場合であっても、回転部材を回転させることができる。 According to such a configuration, since a plurality of wind collecting portions formed along the circumferential direction are provided, the wind can be collected regardless of the wind direction. Thereby, wind can be collected regardless of the wind direction and the rotating member can be rotated.
Moreover, in the air collecting device which concerns on this invention, the direction of the partition plate which partitions off between adjacent air collecting parts is a tangent direction of a rotating member. For this reason, the collected wind can be utilized for the rotation of the rotating member most efficiently. Thereby, even if a wind is a breeze, a rotation member can be rotated.
　また、本発明に係る集風装置の前記構成において、前記集風部は、前記取込口から前記排出口に向かうほど流路断面積が小さくなっていることが好ましい。 Further, in the configuration of the air collecting device according to the present invention, it is preferable that the air collecting portion has a flow passage cross-sectional area that decreases from the intake port toward the discharge port.
　このような構成によれば、取込口から排出口に向かうほど集風部の流路断面積が小さくなっているため、取り込んだ風の流速を上げたうえで、排出口から排出できる。これにより、回転部材の回転速度を上げることができる。また、この回転部材の回転を発電に利用した場合には、効率的に発電することができる。 According to such a configuration, since the cross-sectional area of the air collecting portion becomes smaller toward the discharge port from the intake port, the flow rate of the taken-in air can be increased and discharged from the discharge port. Thereby, the rotational speed of the rotating member can be increased. Further, when the rotation of the rotating member is used for power generation, it is possible to generate power efficiently.
　また、本発明に係る風力回転装置は、前記集風装置と、前記収容部に収容された回転装置とを備えた風力回転装置であって、前記回転装置は、前記排出口から排出される風によって軸回りに回転する前記回転部材と、前記回転部材と同軸に設けられ、軸回りに回転可能な回転軸と、前記回転部材の回転をその回転速度を増速して前記回転軸に伝達する回転伝達機構とを備えていることを特徴とする。 The wind power rotating device according to the present invention is a wind power rotating device including the wind collecting device and a rotating device housed in the housing portion, and the rotating device winds discharged from the discharge port. The rotating member that rotates around the axis by the rotation member, the rotating shaft that is provided coaxially with the rotating member, and that can rotate around the axis, and the rotation of the rotating member is transmitted to the rotating shaft at an increased speed. And a rotation transmission mechanism.
　このような構成によれば、回転部材の回転をその回転速度を増速して回転軸に伝達する回転伝達機構を備えているため、集風部の排出口から排出される空気によって軸回りに回転する回転部材の回転速度が、回転伝達機構によって増速されて回転軸に伝達される。これにより、風が微風であって回転部材の回転速度が低くても、回転軸の回転速度を増速させることができる。また、回転軸の回転を発電に利用した場合には、効率的に発電することができる。 According to such a configuration, since the rotation transmission mechanism that increases the rotation speed of the rotation member and transmits the rotation to the rotation shaft is provided, the air discharged from the discharge port of the air collection unit is rotated around the axis. The rotating speed of the rotating rotating member is increased by the rotation transmitting mechanism and transmitted to the rotating shaft. Thereby, even if a wind is a breeze and the rotational speed of a rotating member is low, the rotational speed of a rotating shaft can be increased. In addition, when the rotation of the rotating shaft is used for power generation, power can be generated efficiently.
　また、本発明に係る風力回転装置の前記構成において、前記回転部材は、径方向外側の側面に、周方向に沿って所定の間隔ごとに立設された薄板状の羽根を備え、前記羽根は、前記回転部材の軸方向に対する寸法である幅の中央部が、前記回転部材の回転方向に向かって突出した湾曲形状となっていることを特徴とする。

Further, in the configuration of the wind power rotating apparatus according to the present invention, the rotating member is provided with thin plate-like blades erected at predetermined intervals along the circumferential direction on a radially outer side surface, The center part of the width which is the dimension with respect to the axial direction of the said rotation member becomes the V shape which protruded toward the rotation direction of the said rotation member, It is characterized by the above-mentioned.
　このような構成によれば、羽根に当たった風が幅方向に逃げるのが阻止されるため、風がより効率的に回転部材の回転に利用され、回転部材がより高速で回転する。回転軸の回転を発電に利用した場合には、効率的に発電することができる。 According to such a configuration, since the wind that hits the blades is prevented from escaping in the width direction, the wind is used more efficiently for the rotation of the rotating member, and the rotating member rotates at a higher speed. When the rotation of the rotating shaft is used for power generation, power can be generated efficiently.

　このような構成によれば、リングギア、プラネタリギアおよびサンギアの歯数や径を調整することによって、回転軸の増速量を容易に調整することができる。 According to such a configuration, the speed increase amount of the rotating shaft can be easily adjusted by adjusting the number of teeth and the diameter of the ring gear, the planetary gear, and the sun gear.
　本発明に係る風力発電装置は、前記風力回転装置を備えた風力発電装置であって、前記回転軸が前記回転部材より軸方向に突出しており、突出している前記回転軸の外側に第１固定部材が設けられ、前記回転軸と前記第１固定部材とのうちのいずれか一方に永久磁石が設けられ、他方にコイルが前記永久磁石と所定の隙間をもって設けられていることを特徴とする。 The wind turbine generator according to the present invention is a wind turbine generator including the wind turbine rotating device, wherein the rotating shaft protrudes in an axial direction from the rotating member, and is fixed to the outside of the protruding rotating shaft.

Speeded. And since a permanent magnet is provided in any one of a rotating shaft and a 1st fixing member and a coil is provided in the other side with the said permanent magnet with the predetermined clearance gap, by cooperation with a permanent magnet and a coil It can generate electricity efficiently.

　以下、図面を参照しながら本発明の第１の実施の形態について説明する。
　図１は、第１の実施の形態に係る風力回転装置１０を示すもので、正面側から見た斜視図である。図２は、風力回転装置１０を上面側から見た図である。なお、図２は、カバー２という部材を取り外した状態を示している。図３は、集風装置３０を正面側から見た斜視図である。図１および図２に示すように、風力回転装置１０は、集風装置３０と、集風装置３０の内部に収容された回転装置５０とを備えている。集風装置３０の底面および回転装置５０の底面は、それぞれ設置面に固定されている。設置面とは、地面や床等である。 The first embodiment of the present invention will be described below with reference to the drawings.
FIG. 1 shows a wind power rotating apparatus 10 according to the first embodiment, and is a perspective view seen from the front side. FIG. 2 is a view of the wind power rotating device 10 as viewed from the upper surface side. FIG. 2 shows a state in which the member called the cover 2 is removed. FIG. 3 is a perspective view of the air collecting device 30 as viewed from the front side. As shown in FIGS. 1 and 2, the wind power rotating device 10 includes a wind collecting device 30 and a rotating device 50 housed inside the wind collecting device 30. The bottom surface of the air collecting device 30 and the bottom surface of the rotating device 50 are respectively fixed to the installation surface. The installation surface is the ground or floor.
　図１に示したカバー２は、集風装置３０の上端に取り付け可能に形成されている部材であり、中央から外周側に向かって下方に傾斜した形状となっている。カバー２を取り付けることで、集風装置３０の内部に雨水等が侵入するのを防ぐことができる。なお、図１に示した金網３は、集風装置３０の排出口３３に取り付け可能に形成されている部材である。金網３を排出口３３に取り付けることで、排出口３３から昆虫や鳥が侵入するのを防ぐことができる。 The cover 2 shown in FIG. 1 is a member that can be attached to the upper end of the air collecting device 30, and has a shape that is inclined downward from the center toward the outer peripheral side. By attaching the cover 2, it is possible to prevent rainwater or the like from entering the inside of the air collecting device 30. Note that the wire mesh 3 shown in FIG. 1 is a member that can be attached to the discharge port 33 of the air collecting device 30. By attaching the wire mesh 3 to the discharge port 33, it is possible to prevent insects and birds from entering from the discharge port 33.
　図３を用いて、集風装置３０について説明する。集風装置３０は、回転装置５０を収容するための円形状の空間である収容部３７が内側に設けられた環状の部材である。集風装置３０は、上面から見た外形が多角形状となっている。集風装置３０の軸と、内部に収容される回転装置５０の軸とは同軸となっている。集風装置３０には、周方向に沿って集風部３１が複数形成されている。集風部３１は、径方向外側に形成された取込口３２から風を取り込むとともに、径方向内側に形成された排出口３３から風を排出する。取込口３２は、風を取り込むために設けられた四角形状の開口である。排出口３３は、取込口３２から取り込んだ風（空気）を排出するために設けられた四角形状の開口である。排出口３３は、集風装置３０の高さ（上下方向）の略中央となる位置に設けられている。また、排出口３３の大きさは、取込口３２の大きさより十分小さく形成されている。集風部３１は、隣り合う集風部３１の間を仕切る仕切り板３４を備えている。 The air collecting device 30 will be described with reference to FIG. The air collecting device 30 is an annular member provided inside with a housing portion 37 that is a circular space for housing the rotating device 50. The air collecting device 30 has a polygonal shape as viewed from above. The axis of the air collecting device 30 and the axis of the rotating device 50 accommodated therein are coaxial. A plurality of air collecting portions 31 are formed in the air collecting device 30 along the circumferential direction. The air collecting unit 31 takes in the wind from the intake port 32 formed on the radially outer side and discharges the wind from the discharge port 33 formed on the radially inner side. The intake port 32 is a rectangular opening provided to take in the wind. The discharge port 33 is a rectangular opening provided for discharging the wind (air) taken in from the intake port 32. The discharge port 33 is provided at a position that is substantially in the center of the height (vertical direction) of the air collecting device 30. Further, the size of the discharge port 33 is formed sufficiently smaller than the size of the intake port 32. The air collecting unit 31 includes a partition plate 34 that partitions between adjacent air collecting units 31.
　図４は、仕切り板３４について説明するための図である。仕切り板３４は、上面から見て放射状に配置されている。図４では、収容部３７の中心を中心Ｏとし、仕切り板３４の径方向内側の端部を端部Ｓとし、中心Ｏと端部Ｓとを結ぶ線分を線分Ｔとている。仕切り板３４は、その向きが線分Ｔと垂直となるように配置されている。すなわち、仕切り板３４は、その向きが円形状である収容部３７の接線方向と同一となるように形成されている。なお、ここでいう同一とは完全同一のみを指すものではなく、略同一を含むものとする。また、仕切り板３４の向きは、後述する回転装置５０におけるファン５１の外周の接線方向と略同一となっているともいえる。また、図４では、すべての仕切り板３４の向きが一様に当該接線方向と略同一となっているものを示しているが、これに限定されるものではなく、任意の仕切り板３４の角度が異なっていてもよい。 FIG. 4 is a diagram for explaining the partition plate 34. The partition plates 34 are arranged radially when viewed from above. In FIG. 4, the center of the accommodating portion 37 is the center O, the radially inner end of the partition plate 34 is the end S, and the line segment connecting the center O and the end S is the line T. The partition plate 34 is arranged so that its direction is perpendicular to the line segment T. That is, the partition plate 34 is formed so that the direction thereof is the same as the tangential direction of the accommodating portion 37 having a circular shape. In addition, the same thing here does not point out only complete identity, but shall include substantially the same. Moreover, it can be said that the direction of the partition plate 34 is substantially the same as the tangential direction of the outer periphery of the fan 51 in the rotating device 50 described later. FIG. 4 shows that all the partition plates 34 are uniformly oriented substantially in the same direction as the tangential direction. However, the present invention is not limited to this, and an arbitrary angle of the partition plate 34 is shown. May be different.
　図３に示すように、集風部３１は、上方板３５および下方板３６を備えている。上方板３５は、上下方向に対して、径方向外側から径方向内側に向かう方向に、斜め下方に傾斜している。下方板３６は、上下方向に対して、径方向外側から径方向内側に向かう方向に、斜め上方に傾斜している。集風部３１では、仕切り板３４、上方板３５、および下方板３６によって風を取り込む流路が形成されており、流路の断面積は取込口３２から排出口３３に向かうほど小さくなっている。
　図５は、集風装置３０の流路における風の流れを説明するための図である。図５に示すように、集風装置３０は、大量の風（平圧空気）を取込口３２から取り込み、仕切り板３４、上方板３５、および下方板３６によって曲げて（絞って）、高密度の高圧風として排出口３３から排出するようになっている。 As shown in FIG. 3, the air collecting unit 31 includes an upper plate 35 and a lower plate 36. The upper plate 35 is inclined obliquely downward in the direction from the radially outer side to the radially inner side with respect to the vertical direction. The lower plate 36 is inclined obliquely upward in the direction from the radially outer side to the radially inner side with respect to the vertical direction. In the air collecting unit 31, a flow path for taking in air is formed by the partition plate 34, the upper plate 35, and the lower plate 36, and the cross-sectional area of the flow path becomes smaller toward the discharge port 33 from the intake port 32. Yes.
FIG. 5 is a diagram for explaining the flow of wind in the flow path of the air collecting device 30. As shown in FIG. 5, the air collecting device 30 takes in a large amount of wind (flat pressure air) from the intake port 32, and bends (squeezes) the partition plate 34, the upper plate 35, and the lower plate 36. The air is discharged from the discharge port 33 as a high-pressure air having a high density.
　図６は、回転装置５０を正面側から見た斜視図である。図７は、回転装置５０の軸方向断面図である。
　図６および図７を用いて、回転装置５０について説明する。回転装置５０は、ファン５１を備えている。ファン５１（回転部材）は、円板状の回転板５１ａと羽根５１ｂとを備えている。
　回転板５１ａにおける径方向外側の側面には、周方向に沿って所定の間隔ごとに複数の羽根５１ｂが立設されている。羽根５１ｂは薄板状の部材であり、回転板５１ａの回転中心から径方向外側に向かう方向に突出するように形成されている。ここで、ファン５１（回転板５１ａ）の軸方向に対する羽根５１ｂの寸法を幅とすると、羽根５１ｂは、幅方向の略中央部が、ファン５１の回転方向に向かって突出した湾曲形状となっている。また、ファン５１の外周の接線方向と集風装置３０の仕切り板３４が設けられている方向とは略同一となっている。ここで、ファン５１の外周とは、図２に示すように、羽根５１ｂを含む状態でのファン５１の外周を指すが、これに限定されるものではなく、後述する図９に示すように、羽根５１ｂを含まない状態でのファン５１の外周（すなわち回転板５１ａの外周）であってもよい。
　集風装置３０の排出口３３から排出される高圧の風（空気）は、ファン５１の外周側に位置する複数の羽根５１ｂに効率的に当たる。これにより、ファン５１がスムーズに回転するようになっている。また、羽根５１ｂに湾曲形状を採用することで、羽根５１ｂに当たった風が幅方向外側に逃げるのが阻止され、風の流れが、より効率的にファン５１の回転に利用されることとなる。また、図５に示すように、ファン５１の回転に利用された風は上下方向に排出されるため、ファン５１の回転の妨げとならない。 FIG. 6 is a perspective view of the rotating device 50 as seen from the front side. FIG. 7 is an axial sectional view of the rotating device 50.
The rotating device 50 will be described with reference to FIGS. 6 and 7. The rotating device 50 includes a fan 51. The fan 51 (rotating member) includes a disk-shaped rotating plate 51a and blades 51b.
A plurality of blades 51b are provided upright at predetermined intervals along the circumferential direction on the radially outer side surface of the rotating plate 51a. The blade 51b is a thin plate-like member, and is formed so as to protrude in the direction toward the radially outer side from the rotation center of the rotating plate 51a. Here, when the dimension of the blade 51b with respect to the axial direction of the fan 51 (rotating plate 51a) is defined as a width, the blade 51b has a curved shape in which a substantially central portion in the width direction protrudes in the rotation direction of the fan 51. Yes. The tangential direction of the outer periphery of the fan 51 and the direction in which the partition plate 34 of the air collecting device 30 is provided are substantially the same. Here, the outer periphery of the fan 51 indicates the outer periphery of the fan 51 in a state including the blades 51b as shown in FIG. 2, but is not limited to this, and as shown in FIG. It may be the outer periphery of the fan 51 (that is, the outer periphery of the rotating plate 51a) in a state where the blade 51b is not included.
The high-pressure wind (air) discharged from the discharge port 33 of the air collecting device 30 efficiently hits the plurality of blades 51 b located on the outer peripheral side of the fan 51. Thereby, the fan 51 rotates smoothly. Further, by adopting a curved shape for the blades 51b, the wind hitting the blades 51b is prevented from escaping to the outside in the width direction, and the flow of the wind is used for the rotation of the fan 51 more efficiently. . Further, as shown in FIG. 5, since the wind used for the rotation of the fan 51 is discharged in the vertical direction, the rotation of the fan 51 is not hindered.
　図７に示すように、ファン５１の内側には、略円筒状の上ケーシング７０が設けられている。上ケーシング７０の下端部にはフランジ部７０ａが形成されている。フランジ部７０ａは、上ケーシング７０の下方に位置し、上ケーシング７０と同軸に設けられた円筒状の下ケーシング７１の上端部に固定されている。
　上ケーシング７０の内側には回転軸７２が、ファン５１の軸と同軸にかつ軸回りに回転可能に設けられている。回転軸７２の上端部と中央部とにはそれぞれフランジ部７２ａ，７２ｂが設けられている。フランジ部７２ａは、上ケーシング７０の上板に回転可能に支持されており、フランジ部７２ｂは、上ケーシング７０の下部のフランジ部７０ａに回転可能に支持されている。 As shown in FIG. 7, a substantially cylindrical upper casing 70 is provided inside the fan 51. A flange portion 70 a is formed at the lower end portion of the upper casing 70. The flange portion 70 a is positioned below the upper casing 70 and is fixed to an upper end portion of a cylindrical lower casing 71 provided coaxially with the upper casing 70.
A rotating shaft 72 is provided inside the upper casing 70 so as to be coaxial with the axis of the fan 51 and rotatable about the axis. Flange portions 72a and 72b are provided at the upper end portion and the central portion of the rotating shaft 72, respectively. The flange portion 72 a is rotatably supported by the upper plate of the upper casing 70, and the flange portion 72 b is rotatably supported by the flange portion 70 a at the lower portion of the upper casing 70.
　また、回転軸７２はフランジ部７０ａを貫通してファン５１より軸方向でかつ下方に突出しており、当該回転軸７２の下端部にフランジ部７２ｃが設けられている。このフランジ部７２ｃが下ケーシング７１の下端部に設けられた円板状の基板７３の中央部に回転可能に支持されている。すなわち、基板７３の中央部には孔が形成され、この孔にフランジ部７２ｃが回転可能に設けられ、さらに、回転軸７２の下端部およびフランジ部７２ｃと、基板７３の中央部に設けられた孔との間にはアンギュラ軸受７４が設けられている。 The rotating shaft 72 passes through the flange portion 70 a and protrudes downward in the axial direction from the fan 51. A flange portion 72 c is provided at the lower end portion of the rotating shaft 72. The flange portion 72c is rotatably supported by the central portion of a disc-shaped substrate 73 provided at the lower end portion of the lower casing 71. That is, a hole is formed in the central portion of the substrate 73, and a flange portion 72 c is rotatably provided in the hole. Further, the lower end portion of the rotating shaft 72 and the flange portion 72 c and the central portion of the substrate 73 are provided. An angular bearing 74 is provided between the holes.
　また、ファン５１の内側でかつ上ケーシング７０の外側には、円筒状の回転体７５がファン５１と同軸にかつ同期して回転可能に設けられている。上ケーシング７０の外周面と回転体７５の内周面との間には、上下一対の軸受７６，７６が設けられ、さらに、上ケーシング７０の下端部とフランジ部７０ａと回転体７５の下端部との間にはアンギュラ軸受７７が設けられている。これにより、回転体７５は上ケーシング７０に回転可能に支持されている。 Further, a cylindrical rotating body 75 is provided on the inner side of the fan 51 and on the outer side of the upper casing 70 so as to be rotatable coaxially and synchronously with the fan 51. A pair of upper and lower bearings 76, 76 are provided between the outer peripheral surface of the upper casing 70 and the inner peripheral surface of the rotating body 75, and the lower end portion of the upper casing 70, the flange portion 70 a, and the lower end portion of the rotating body 75. Between them, an angular bearing 77 is provided. Thereby, the rotary body 75 is rotatably supported by the upper casing 70.
　そして、上ケーシング７０の上側には、ファン５１の回転をその回転速度を増速して回転軸７２に伝達する回転伝達機構８０が設けられている。
　回転伝達機構８０は、遊星歯車機構によって構成されている。回転伝達機構８０は、上ケーシング７０と回転板５１ａの上板との間に設けられており、リングギア８１と、このリングギア８１の回転中心に設けられたサンギア８２と、複数のプラネタリギア８３とを備えている。なお、リングギア８１の回転中心は回転軸７２の回転中心と一致している。
　回転板５１ａの上板の下面にリングギア８１の上面が固定され、このリングギア８１の下面と外周面とに回転体７５が固定されている。したがって、ファン５１が回転することによりリングギア８１および回転体７５が同期して回転するようになっている。
　また、回転軸７２の上端部はサンギア８２に挿入されて固定されており、サンギア８２が回転することによって回転軸７２が回転するようになっている。
　さらに、プラネタリギア８３は、リングギア８１およびサンギア８２に噛合しており、リングギア８１が回転することによって、自転しつつサンギア８２の周囲を公転するようになっている。したがって、リングギア８１が回転すると、プラネタリギア８３がリングギア８１の内側を自転しながら公転して回転移動し、これによってサンギア８２が軸回りに回転するようになっている。 On the upper side of the upper casing 70, a rotation transmission mechanism 80 that increases the rotation speed of the fan 51 and transmits the rotation to the rotation shaft 72 is provided.
The rotation transmission mechanism 80 is constituted by a planetary gear mechanism. The rotation transmission mechanism 80 is provided between the upper casing 70 and the upper plate of the rotary plate 51a, and includes a ring gear 81, a sun gear 82 provided at the rotation center of the ring gear 81, and a plurality of planetary gears 83. And. Note that the rotation center of the ring gear 81 coincides with the rotation center of the rotation shaft 72.
The upper surface of the ring gear 81 is fixed to the lower surface of the upper plate of the rotating plate 51a, and the rotating body 75 is fixed to the lower surface and the outer peripheral surface of the ring gear 81. Therefore, as the fan 51 rotates, the ring gear 81 and the rotating body 75 rotate in synchronization.
Further, the upper end portion of the rotating shaft 72 is inserted and fixed to the sun gear 82, and the rotating shaft 72 is rotated when the sun gear 82 rotates.
Further, the planetary gear 83 meshes with the ring gear 81 and the sun gear 82, and the ring gear 81 rotates to revolve around the sun gear 82 while rotating. Therefore, when the ring gear 81 rotates, the planetary gear 83 revolves and rotates while rotating inside the ring gear 81, whereby the sun gear 82 rotates about the axis.
　そして、リングギア８１がファン５１によって１回転すると、サンギア８２が１０回転するように、リングギア８１、プラネタリギア８３およびサンギア８２の歯数や径が設定されている。したがって、このような回転伝達機構８０では、ファン５１の回転速度を１０倍に増速してサンギア８２が回転し、この回転によって回転軸７２がファン５１より１０倍の回転速度で回転するようになっている。 Then, the number of teeth and the diameter of the ring gear 81, the planetary gear 83, and the sun gear 82 are set so that the sun gear 82 rotates 10 times when the ring gear 81 rotates once by the fan 51. Therefore, in such a rotation transmission mechanism 80, the rotation speed of the fan 51 is increased 10 times and the sun gear 82 rotates, and the rotation shaft 72 rotates at a rotation speed 10 times that of the fan 51 by this rotation. It has become.
　次に、風力回転装置１０が風力発電装置として利用される場合について説明する。
　回転軸７２は上ケーシング７０から下方に突出して、下端部が下ケーシング（第１固定部材）７１に位置している。下ケーシング７１の内周面にはコイル８５が固定されており、一方、回転軸７２の下端部には永久磁石８６がコイル８５との間に所定の隙間をもって固定されている。そして、コイル８５と永久磁石８６との協働によって発電され、発電された電気はバッテリーに蓄電されたり、直接使用されるようになっている。なお、下ケーシング７１に永久磁石８６を固定し、回転軸７２にコイル８５を固定してもよい。
　また、永久磁石８６の外周面には、図示は省略するが、回転軸７２に対して傾斜する傾斜溝が周方向に所定間隔で複数互いに平行に形成されている。そして、永久磁石８６が回転軸７２によって回転すると、傾斜溝によって、永久磁石８６より下方にある空間から空気を吸い込んで、下ケーシング７１の内部に吹き出して、当該内部を冷却するようになっている。つまり、永久磁石８６は発電機能に加えて冷却機能を備えている。 Next, the case where the wind rotating apparatus 10 is used as a wind power generator will be described.
The rotating shaft 72 protrudes downward from the upper casing 70, and the lower end portion is positioned on the lower casing (first fixing member) 71. A coil 85 is fixed to the inner peripheral surface of the lower casing 71, while a permanent magnet 86 is fixed to the lower end portion of the rotating shaft 72 with a predetermined gap between the coil 85. Then, power is generated by the cooperation of the coil 85 and the permanent magnet 86, and the generated electricity is stored in a battery or used directly. Note that the permanent magnet 86 may be fixed to the lower casing 71 and the coil 85 may be fixed to the rotating shaft 72.
Although not shown in the drawing, a plurality of inclined grooves that are inclined with respect to the rotating shaft 72 are formed on the outer peripheral surface of the permanent magnet 86 at a predetermined interval in the circumferential direction. When the permanent magnet 86 is rotated by the rotating shaft 72, air is sucked from the space below the permanent magnet 86 by the inclined groove and blown out into the lower casing 71 to cool the inside. . That is, the permanent magnet 86 has a cooling function in addition to the power generation function.
　また、回転体７５の内側には、上述したように上ケーシング（第２固定部材）７０が設けられており、この上ケーシング７０の外周面に円筒状のコイル８７が固定され、一方、回転体７５の内周面には永久磁石８８がコイル８７との間に所定の間隔をもって固定されている。そして、コイル８７と永久磁石８８との協働によって発電され、発電された電気はバッテリーに蓄電されたり、直接使用されるようになっている。なお、上ケーシング７０に永久磁石８８を固定し、回転体７５にコイル８７を固定してもよい。 Further, as described above, the upper casing (second fixing member) 70 is provided inside the rotating body 75, and a cylindrical coil 87 is fixed to the outer peripheral surface of the upper casing 70. A permanent magnet 88 is fixed to the inner peripheral surface of the coil 75 at a predetermined interval from the coil 87. Then, power is generated by the cooperation of the coil 87 and the permanent magnet 88, and the generated electricity is stored in a battery or used directly. Alternatively, the permanent magnet 88 may be fixed to the upper casing 70 and the coil 87 may be fixed to the rotating body 75.
　第１の実施形態に係る風力回転装置１０は、例えばビルの屋上、住宅の屋根等に設置される。集風装置３０では、取込口３２から風が取り込まれると、集風装置３０は取込口３２から排出口３３に向かうほど流路断面積が小さくなっているので、取り込んだ風（空気）は、高密度の高圧風としてその流速を上げられたうえで、排出口３３から排出される。排出口３３から排出された空気は、ファン５１の一部（数枚）の羽根５１ｂに次々に当たり、ファン５１を回転させる。ファン５１が回転することによって、回転伝達機構８０のリングギア８１が回転し、当該リングギア８１とともに回転体７５が回転する。 The wind power rotating apparatus 10 according to the first embodiment is installed on the roof of a building, the roof of a house, or the like, for example. In the air collecting device 30, when the wind is taken in from the intake port 32, the cross-sectional area of the air collecting device 30 decreases from the intake port 32 toward the discharge port 33. Is discharged from the discharge port 33 after its flow velocity is increased as a high-density high-pressure wind. The air discharged from the discharge port 33 sequentially hits some (several) blades 51b of the fan 51 to rotate the fan 51. As the fan 51 rotates, the ring gear 81 of the rotation transmission mechanism 80 rotates, and the rotating body 75 rotates together with the ring gear 81.
　回転体７５には永久磁石８８が固定されているので、当該永久磁石８８も回転体７５とともに回転する。一方、回転体７５の内側に設けられている上ケーシング７０にはコイル８７が固定されているので、コイル８７と永久磁石８８との協働によって発電され、発電された電気はバッテリーに蓄電されたり、直接使用される。 Since the permanent magnet 88 is fixed to the rotating body 75, the permanent magnet 88 also rotates together with the rotating body 75. On the other hand, since the coil 87 is fixed to the upper casing 70 provided inside the rotating body 75, power is generated by the cooperation of the coil 87 and the permanent magnet 88, and the generated electricity is stored in the battery. Used directly.
　また、ファン５１の回転によって回転伝達機構８０のリングギア８１が回転すると、プラネタリギア８３を介してサンギア８２が回転する。サンギア８２が回転すると、サンギア８２とともに回転軸７２が回転する。この回転軸７２の回転速度は回転伝達機構８０によってリングギア８１の回転速度、つまりファン５１の回転速度の１０倍に増速される。 Further, when the ring gear 81 of the rotation transmission mechanism 80 is rotated by the rotation of the fan 51, the sun gear 82 is rotated via the planetary gear 83. When the sun gear 82 rotates, the rotating shaft 72 rotates together with the sun gear 82. The rotation speed of the rotation shaft 72 is increased by the rotation transmission mechanism 80 to 10 times the rotation speed of the ring gear 81, that is, the rotation speed of the fan 51.
　回転軸７２の下端部には永久磁石８６が固定されているので、当該永久磁石８６は回転軸７２とともに回転する。一方、回転軸７２の外側に設けられている下ケーシング７１にはコイル８５が固定されているので、コイル８５と永久磁石８６との協働によって発電され、発電された電気はバッテリーに蓄電されたり、直接使用される。コイル８５はコイル８７より回転速度が１０倍速いので、コイル８５と永久磁石８６との協働による発電力は、コイル８７と永久磁石８８の協働による発電力より大きくなる。 Since the permanent magnet 86 is fixed to the lower end portion of the rotating shaft 72, the permanent magnet 86 rotates together with the rotating shaft 72. On the other hand, since the coil 85 is fixed to the lower casing 71 provided outside the rotating shaft 72, power is generated by the cooperation of the coil 85 and the permanent magnet 86, and the generated electricity is stored in the battery. Used directly. Since the rotational speed of the coil 85 is 10 times faster than that of the coil 87, the power generated by the cooperation of the coil 85 and the permanent magnet 86 is larger than the power generated by the cooperation of the coil 87 and the permanent magnet 88.
　以上のように、第１の実施の形態によれば、集風装置３０は、周方向に沿って複数形成された集風部３１を備えている。このため、風向きがいずれの方向であっても、風を集めることができる。これにより、風向きに左右されず風を集め、集めた風を回転部材５１の回転に利用することができる。また、隣り合う集風部３１の間を仕切る仕切り板の方向が、回転部材５１の接線方向となっているため。このため、集めた風を最も効率的に回転部材５１の回転に利用することができる。これにより、風が微風の場合であっても、回転部材５１を回転させることができる。 As described above, according to the first embodiment, the air collecting device 30 includes the air collecting portions 31 formed in a plurality along the circumferential direction. For this reason, the wind can be collected regardless of the wind direction. Thereby, the wind can be collected regardless of the wind direction, and the collected wind can be used for the rotation of the rotating member 51. Further, the direction of the partition plate that partitions the adjacent air collecting portions 31 is the tangential direction of the rotating member 51. For this reason, the collected wind can be utilized for the rotation of the rotating member 51 most efficiently. Thereby, even if a wind is a breeze, the rotation member 51 can be rotated.
　また、集風装置３０の集風部３１は、取込口３２から排出口３３に向かうほど流路断面積が小さくなっている。このため、取り込んだ風の流速を上げたうえで、排出口３３から排出できる。これにより、回転部材５１の回転速度を上げることができ、発電効率を向上させることができる。 Further, the air flow collecting section 31 of the air collecting device 30 has a flow passage cross-sectional area that decreases from the intake port 32 toward the discharge port 33. For this reason, it can discharge from the discharge port 33, after raising the flow velocity of the taken-in wind. Thereby, the rotational speed of the rotating member 51 can be increased, and the power generation efficiency can be improved.
　また、回転装置５０は、回転部材５１の回転をその回転速度を増速して回転軸７２に伝達する回転伝達機構８０を備えているので、集風部３１の排出口３３から排出される風（空気）によって軸回りに回転する回転部材５１の回転速度が、回転伝達機構８０によって増速されて回転軸７２に伝達される。このため、風が微風であって回転部材５１の回転速度が低くても、回転軸７２の回転速度が増速させることができ、発電効率を向上させることができる。 In addition, the rotation device 50 includes the rotation transmission mechanism 80 that increases the rotation speed of the rotation member 51 and transmits the rotation to the rotation shaft 72, so that the wind discharged from the discharge port 33 of the air collecting unit 31 is provided. The rotation speed of the rotating member 51 that rotates about the axis by (air) is increased by the rotation transmitting mechanism 80 and transmitted to the rotating shaft 72. For this reason, even if the wind is light and the rotation speed of the rotating member 51 is low, the rotation speed of the rotating shaft 72 can be increased and the power generation efficiency can be improved.
　また、回転部材５１における径方向外側の側面には羽根５１ｂが立設されており、羽根５１ｂは湾曲形状を有している。このため、羽根５１ｂに当たった風が幅方向外側に逃げるのが阻止され、風の流れがより効率的に回転部材５１の回転に利用されて、回転部材５１がより高速で回転する。これにより、発電効率を向上させることができる。 Also, a blade 51b is provided upright on the radially outer side surface of the rotating member 51, and the blade 51b has a curved shape. For this reason, it is prevented that the wind which hit the blade | wing 51b escapes to the width direction outer side, the flow of a wind is utilized more efficiently for rotation of the rotation member 51, and the rotation member 51 rotates at higher speed. Thereby, power generation efficiency can be improved.
　また、回転装置５０において、回転伝達機構８０のリングギア８１が回転部材５１に取り付けられ、サンギア８２が回転軸７２に取り付けられ、プラネタリギア８３がリングギア８１およびサンギア８２に噛合しているので、リングギア８１、プラネタリギア８３およびサンギア８２の歯数や径を調整することによって、回転軸７２の増速量を容易に調整できる。 In the rotating device 50, the ring gear 81 of the rotation transmission mechanism 80 is attached to the rotating member 51, the sun gear 82 is attached to the rotating shaft 72, and the planetary gear 83 is engaged with the ring gear 81 and the sun gear 82. By adjusting the number of teeth and the diameter of the ring gear 81, the planetary gear 83, and the sun gear 82, the speed increase amount of the rotating shaft 72 can be easily adjusted.
　また、回転軸７２が回転部材５１より軸方向に下方に突出しており、この突出している回転軸７２の外側に第１固定部材としての下ケーシング７１が設けられ、この下ケーシング７１にコイル８５が設けられ、回転軸７２の下端部に永久磁石８６が設けられており、さらに、回転伝達機構８０によって回転部材５１の回転が増速されて回転軸７２に伝達されるので、微風等の場合に回転部材５１の回転速度が低くても、永久磁石８６とコイル８５との協働によって効率的に発電できる。 Further, the rotating shaft 72 protrudes downward in the axial direction from the rotating member 51, and a lower casing 71 as a first fixing member is provided outside the protruding rotating shaft 72, and a coil 85 is provided in the lower casing 71. Since the permanent magnet 86 is provided at the lower end of the rotating shaft 72 and the rotation of the rotating member 51 is accelerated by the rotation transmitting mechanism 80 and transmitted to the rotating shaft 72, in the case of a light wind or the like. Even when the rotation speed of the rotating member 51 is low, power can be generated efficiently by the cooperation of the permanent magnet 86 and the coil 85.
　さらに、回転部材５１にリングギア８１を介して回転体７５が設けられ、この回転体７５に永久磁石８８が設けられ、第２固定部材としての上ケーシング７０にコイル８７が設けられているので、永久磁石８８とコイル８７との協働によって効率的に発電できる。つまり、回転軸７２の回転による、永久磁石８６とコイル８５との協働によって発電できるとともに、回転体７５の回転による永久磁石８８とコイル８７との協働によって発電できるので、２系統で発電できる。 Furthermore, the rotating member 75 is provided on the rotating member 51 via the ring gear 81, the permanent magnet 88 is provided on the rotating member 75, and the coil 87 is provided on the upper casing 70 as the second fixing member. Electric power can be generated efficiently by the cooperation of the permanent magnet 88 and the coil 87. That is, power can be generated by the cooperation of the permanent magnet 86 and the coil 85 by the rotation of the rotating shaft 72, and power can be generated by the cooperation of the permanent magnet 88 and the coil 87 by the rotation of the rotating body 75. .
　なお、第１の実施の形態では、回転部材５１の回転をその回転速度を増速して回転軸７２に伝達する回転伝達機構８０として遊星歯車機構を採用したが、回転部材５１の回転をその回転速度を増速して回転軸７２に伝達できる機構であれば、他の回転伝達機構を採用してもよい。 In the first embodiment, the planetary gear mechanism is employed as the rotation transmission mechanism 80 that transmits the rotation of the rotation member 51 to the rotation shaft 72 while increasing the rotation speed thereof. Other rotation transmission mechanisms may be adopted as long as the rotation speed can be increased and transmitted to the rotation shaft 72.
　次に、本発明の第２の実施の形態について説明する。図８は、第２の実施の形態に係る風力回転装置１１を示すもので、正面側から見た斜視図である。図９は、第２の実施の形態に係る風力回転装置１１を上面側から見た図である。以下、第１の実施の形態で説明した構成と同一または相当する機能を有する構成については、同一の符号を付し、その説明を省略または簡略化する。 Next, a second embodiment of the present invention will be described. FIG. 8 shows the wind power rotating device 11 according to the second embodiment, and is a perspective view seen from the front side. FIG. 9 is a view of the wind rotating device 11 according to the second embodiment as viewed from the upper surface side. Hereinafter, components having the same or corresponding functions as those described in the first embodiment are denoted by the same reference numerals, and description thereof is omitted or simplified.
　図８および図９に示すように、風力回転装置１１は、集風装置４０と回転装置６０とを備えている。回転装置６０は、集風装置４０の内部に収容されている。図示を省略しているが、集風装置４０の上端には、図１と同様にカバー２を取り付けることができる。
　図８に示すように、集風装置４０における排出口３３は、集風装置４０の下部側に設けられており、下方板３６は設置面と水平となるように形成されている。 As shown in FIGS. 8 and 9, the wind power rotating device 11 includes a wind collecting device 40 and a rotating device 60. The rotating device 60 is housed inside the air collecting device 40. Although not shown, the cover 2 can be attached to the upper end of the air collecting device 40 as in FIG.
As shown in FIG. 8, the outlet 33 in the air collecting device 40 is provided on the lower side of the air collecting device 40, and the lower plate 36 is formed to be horizontal with the installation surface.
　仕切り板３４、上方板３５、および下方板３６によって風を取り込む流路が形成されており、流路の断面積は取込口３２から排出口３３に向かうほど小さくなっている。
　図１０は、集風装置４０の流路における風の流れを説明するための図である。図１０に示すように、集風装置４０は、大量の風（平圧空気）を取込口３２から取り込み、仕切り板３４、上方板３５、および下方板３６によって曲げて（絞って）、高密度の高圧風として排出口３３から排出するようになっている。 The partition plate 34, the upper plate 35, and the lower plate 36 form a flow path for taking in air, and the cross-sectional area of the flow path becomes smaller from the intake port 32 toward the discharge port 33.
FIG. 10 is a view for explaining the flow of wind in the flow path of the air collecting device 40. As shown in FIG. 10, the air collecting device 40 takes in a large amount of wind (flat pressure air) from the intake port 32, and bends (squeezes) the partition plate 34, the upper plate 35, and the lower plate 36. The air is discharged from the discharge port 33 as a high-pressure air having a high density.
　図１１は、回転装置６０を正面側から見た斜視図である。図１２は、風力回転装置１１の軸方向断面図である。図１２に示すように、ファン５１は、回転装置６０の下部側であって、集風装置４０における排出口３３の高さに対応する位置に設けられている。これにより、排出口３３から排出された空気がファン５１の羽根５１ｂに次々に当たり、ファン５１が回転する。また、回転装置６０には、軸方向に対して直交するように配置されたシャフト６１が連結されている。当該連結については後述する。シャフト６１は、仕切り板３４および上方板３５に設けられた孔に挿通されており、端部６１ａが風力回転装置１１（集風装置４０）の外部に露出している。 FIG. 11 is a perspective view of the rotating device 60 as viewed from the front side. FIG. 12 is an axial cross-sectional view of the wind power rotating device 11. As shown in FIG. 12, the fan 51 is provided on the lower side of the rotating device 60 and at a position corresponding to the height of the discharge port 33 in the air collecting device 40. Thereby, the air discharged from the discharge port 33 sequentially hits the blades 51b of the fan 51, and the fan 51 rotates. The rotating device 60 is connected to a shaft 61 arranged so as to be orthogonal to the axial direction. The connection will be described later. The shaft 61 is inserted through holes provided in the partition plate 34 and the upper plate 35, and the end 61 a is exposed to the outside of the wind power rotating device 11 (the air collecting device 40).
　図１３は、回転装置６０の軸方向断面図である。ファン５１の内側には、略円筒状の下ケーシング９１が設けられている。下ケーシング９１の内側には下回転軸９２が、ファン５１の軸と同軸にかつ軸回りに回転可能に設けられている。下回転軸９２と下ケーシング９１との間には、上下一対の軸受９３，９３が設けられている。これにより、下回転軸９２は下ケーシング９１に回転可能に支持されている。また、ファン５１の内側でかつ下ケーシング９１の外側には、円筒状の回転体９５がファン５１と同軸にかつ同期して回転可能に設けられている。下ケーシング９１の外周面と回転体９５の内周面との間には、上下一対の軸受９６，９６が設けられ、さらに、下ケーシング９１の下部側に形成されたフランジ部と回転体９５の下端部との間にはアンギュラ軸受９７が設けられている。これにより、回転体９５は下ケーシング９１に回転可能に支持されている。 FIG. 13 is a sectional view in the axial direction of the rotating device 60. A substantially cylindrical lower casing 91 is provided inside the fan 51. A lower rotating shaft 92 is provided inside the lower casing 91 so as to be coaxial with the axis of the fan 51 and rotatable about the axis. A pair of upper and lower bearings 93, 93 are provided between the lower rotating shaft 92 and the lower casing 91. Thereby, the lower rotating shaft 92 is rotatably supported by the lower casing 91. A cylindrical rotating body 95 is provided on the inner side of the fan 51 and on the outer side of the lower casing 91 so as to be rotatable coaxially and synchronously with the fan 51. A pair of upper and lower bearings 96, 96 are provided between the outer peripheral surface of the lower casing 91 and the inner peripheral surface of the rotating body 95. Further, the flange portion formed on the lower side of the lower casing 91 and the rotating body 95 An angular bearing 97 is provided between the lower end portions. Thereby, the rotary body 95 is rotatably supported by the lower casing 91.
　下ケーシング９１の上側には、ファン５１の回転をその回転速度を増速して下回転軸９２に伝達する回転伝達機構８０が設けられている。
　回転伝達機構８０は、遊星歯車機構によって構成されている。回転伝達機構８０は、下ケーシング９１と回転板５１ａの上板との間に設けられており、リングギア８１と、このリングギア８１の回転中心に設けられたサンギア８２と、複数のプラネタリギア８３とを備えている。なお、リングギア８１の回転中心は下回転軸９２の回転中心と一致している。
　回転板５１ａの上板の下面にリングギア８１の上面が固定され、このリングギア８１の下面と外周面とに回転体９５が固定されている。したがって、ファン５１が回転することによりリングギア８１および回転体９５が同期して回転するようになっている。
　また、下回転軸９２の上端部はサンギア８２に挿入されて固定されており、サンギア８２が回転することによって下回転軸９２が回転するようになっている。
　さらに、プラネタリギア８３は、リングギア８１およびサンギア８２に噛合しており、リングギア８１が回転することによって、自転しつつサンギア８２の周囲を公転するようになっている。したがって、リングギア８１が回転すると、プラネタリギア８３がリングギア８１の内側を自転しながら公転して回転移動し、これによってサンギア８２が軸回りに回転するようになっている。 A rotation transmission mechanism 80 that transmits the rotation of the fan 51 to the lower rotation shaft 92 while increasing the rotation speed is provided on the upper side of the lower casing 91.
The rotation transmission mechanism 80 is constituted by a planetary gear mechanism. The rotation transmission mechanism 80 is provided between the lower casing 91 and the upper plate of the rotating plate 51 a, a ring gear 81, a sun gear 82 provided at the rotation center of the ring gear 81, and a plurality of planetary gears 83. And. The rotation center of the ring gear 81 coincides with the rotation center of the lower rotation shaft 92.
The upper surface of the ring gear 81 is fixed to the lower surface of the upper plate of the rotating plate 51a, and the rotating body 95 is fixed to the lower surface and the outer peripheral surface of the ring gear 81. Therefore, as the fan 51 rotates, the ring gear 81 and the rotating body 95 rotate in synchronization.
Further, the upper end portion of the lower rotating shaft 92 is inserted and fixed in the sun gear 82, and the lower rotating shaft 92 is rotated by the rotation of the sun gear 82.
Further, the planetary gear 83 meshes with the ring gear 81 and the sun gear 82, and the ring gear 81 rotates to revolve around the sun gear 82 while rotating. Therefore, when the ring gear 81 rotates, the planetary gear 83 revolves and rotates while rotating inside the ring gear 81, whereby the sun gear 82 rotates about the axis.
　そして、リングギア８１がファン５１によって１回転すると、サンギア８２が１０回転するように、リングギア８１、プラネタリギア８３およびサンギア８２の歯数や径が設定されている。したがって、このような回転伝達機構８０では、ファン５１の回転速度を１０倍に増速してサンギア８２が回転し、この回転によって下回転軸９２がファン５１より１０倍の回転速度で回転するようになっている。 Then, the number of teeth and the diameter of the ring gear 81, the planetary gear 83, and the sun gear 82 are set so that the sun gear 82 rotates 10 times when the ring gear 81 rotates once by the fan 51. Therefore, in such a rotation transmission mechanism 80, the sun gear 82 rotates by increasing the rotation speed of the fan 51 by 10 times, and this rotation causes the lower rotating shaft 92 to rotate at a rotation speed 10 times that of the fan 51. It has become.
　下回転軸９２は下ケーシング９１およびサンギア８２を貫通してファン５１より軸方向でかつ上方に突出している。下回転軸９２の上端部には、上回転軸１０２が連結されている。上回転軸１０２は、略円筒状の上ケーシング１０１の内側に収容され、下回転軸９２と連結される下端部が上ケーシング１０１より下方に突出している。
　上回転軸１０２と上ケーシング１０１との間には、上下一対の軸受１０３，１０３が設けられている。これにより、上回転軸１０２は上ケーシング１０１に回転可能に支持されている。上回転軸１０２は、下回転軸９２と同軸にかつ同期して回転可能な状態となっている。 The lower rotating shaft 92 passes through the lower casing 91 and the sun gear 82 and protrudes axially and upward from the fan 51. An upper rotary shaft 102 is connected to the upper end portion of the lower rotary shaft 92. The upper rotating shaft 102 is accommodated inside the substantially cylindrical upper casing 101, and a lower end portion connected to the lower rotating shaft 92 projects downward from the upper casing 101.
A pair of upper and lower bearings 103 and 103 are provided between the upper rotating shaft 102 and the upper casing 101. Thereby, the upper rotating shaft 102 is rotatably supported by the upper casing 101. The upper rotating shaft 102 is in a state where it can rotate coaxially and synchronously with the lower rotating shaft 92.
　上ケーシング１０１の側方には、シャフト６１を支持する略円筒状の側方ケーシング１１１が連結されている。シャフト６１は、側方ケーシング１１１を水平方向に貫通し、シャフト６１と側方ケーシング１１１との間には、左右一対の軸受１１２，１１２が設けられている。これにより、シャフト６１は側方ケーシング１１１に回転可能に支持されている。また、シャフト６１の端部は、上ケーシング１０１の側壁を貫通して上ケーシング１０１の内側に収容されている。 A substantially cylindrical side casing 111 that supports the shaft 61 is connected to the side of the upper casing 101. The shaft 61 penetrates the side casing 111 in the horizontal direction, and a pair of left and right bearings 112, 112 are provided between the shaft 61 and the side casing 111. Thereby, the shaft 61 is rotatably supported by the side casing 111. Further, the end portion of the shaft 61 passes through the side wall of the upper casing 101 and is accommodated inside the upper casing 101.
　上回転軸１０２の軸方向とシャフト６１の軸方向とは直交しており、上ケーシング１０１の内側には、上回転軸１０２の回転をシャフト６１に伝達する傘歯車機構１２０が設けられている。傘歯車機構１２０は、第一コーンギア１２１と第二コーンギア１２２とからなる。
　上ケーシング１０１の内側に収容されている上回転軸１０２には、第一コーンギア１２１が挿入されて固定されている。また、上ケーシング１０１の内側に収容されているシャフト６１の端部には、第一コーンギア１２１と噛合する第二コーンギア１２２が挿入されて固定されている。これにより、第一コーンギア１２１が１回転すると第二コーンギア１２２が１回転し、上回転軸１０２の回転がシャフト６１に伝達されて、シャフト６１が回転するようになっている。 The axial direction of the upper rotating shaft 102 and the axial direction of the shaft 61 are orthogonal to each other, and a bevel gear mechanism 120 that transmits the rotation of the upper rotating shaft 102 to the shaft 61 is provided inside the upper casing 101. The bevel gear mechanism 120 includes a first cone gear 121 and a second cone gear 122.
A first cone gear 121 is inserted and fixed to the upper rotating shaft 102 housed inside the upper casing 101. A second cone gear 122 that meshes with the first cone gear 121 is inserted into and fixed to the end portion of the shaft 61 housed inside the upper casing 101. As a result, when the first cone gear 121 rotates once, the second cone gear 122 rotates once, the rotation of the upper rotating shaft 102 is transmitted to the shaft 61, and the shaft 61 rotates.
　図１２に示すように、シャフト６１は、回転装置６０に連結されている側とは反対側の端部６１ａが外部に露出している。端部６１ａには、不図示の発電機が連結されている。この発電機には、例えば、シャフト６１とともに回転する永久磁石と、所定の間隔を設けて当該永久磁石の周囲に固定配置されたコイルとが設けられており、永久磁石とコイルとの協働によって発電されるようになっている。発電された電機はバッテリーに蓄電されたり、直接使用される。
　上記では、端部６１ａに発電機が連結されるものとしたが、これに限定されるものではなく、端部６１ａにコンプレッサー、ポンプ等が連結されるようにしてもよい。端部６１ａにコンプレッサーが連結されている場合、例えば、シャフト６１の回転がピストンの往復運動に変換され、高圧に圧縮された冷媒が排出される。また、端部６１ａにポンプが連結されている場合、例えば、シャフト６１の回転がピストンの往復運動に変換され、水を汲み上げることができる。 As shown in FIG. 12, the shaft 61 has an end portion 61a opposite to the side connected to the rotating device 60 exposed to the outside. A generator (not shown) is connected to the end 61a. This generator is provided with, for example, a permanent magnet that rotates together with the shaft 61, and a coil that is fixedly arranged around the permanent magnet with a predetermined interval, and by cooperation of the permanent magnet and the coil. Electricity is being generated. The generated electric machine is stored in a battery or used directly.
In the above description, the generator is connected to the end portion 61a. However, the present invention is not limited to this, and a compressor, a pump, or the like may be connected to the end portion 61a. When a compressor is connected to the end portion 61a, for example, the rotation of the shaft 61 is converted into a reciprocating motion of a piston, and the refrigerant compressed to a high pressure is discharged. Moreover, when the pump is connected with the edge part 61a, rotation of the shaft 61 is converted into the reciprocating motion of a piston, for example, and water can be pumped up.
　集風装置４０と回転装置６０とを備えた風力回転装置１１は、例えばビルの屋上、住宅の屋根等に設置される。集風装置４０では、取込口３２から風が取り込まれると、集風装置３０は取込口３２から排出口３３に向かうほど流路断面積が小さくなっているので、取り込んだ風（空気）は、高密度の高圧風としてその流速を上げられたうえで、排出口３３から排出される。排出口３３から排出された空気は、ファン５１の一部（数枚）の羽根５１ｂに次々に当たり、ファン５１を回転させる。ファン５１が回転することによって、回転伝達機構８０のリングギア８１が回転し、当該リングギア８１とともに回転体９５が回転する。 The wind power rotating device 11 including the wind collecting device 40 and the rotating device 60 is installed on the roof of a building, the roof of a house, or the like, for example. In the air collecting device 40, when the wind is taken in from the intake port 32, the flow collecting device 30 has a smaller channel cross-sectional area from the intake port 32 toward the discharge port 33. Is discharged from the discharge port 33 after its flow velocity is increased as a high-density high-pressure wind. The air discharged from the discharge port 33 sequentially hits some (several) blades 51b of the fan 51 to rotate the fan 51. As the fan 51 rotates, the ring gear 81 of the rotation transmission mechanism 80 rotates, and the rotating body 95 rotates together with the ring gear 81.
　以上のように、第２の実施の形態によれば、風力回転装置１１が、下回転軸９２の軸方向と直交する方向を軸とし、軸回りに回転可能なシャフト６１と、下回転軸９２の回転をシャフト６１の回転に変換する傘歯車機構１２０とを備え、シャフト６１の一端が集風装置４０の外部に露出しているので、シャフト６１の回転を、発電機、コンプレッサー、ポンプ等の動力源として利用することができる。このように、風力によって得られたクリーンなエネルギーを動力源とすることで、例えば、環境汚染等を抑制することができる。 As described above, according to the second embodiment, the wind turbine rotating apparatus 11 has the shaft 61 that can rotate around the axis about the direction orthogonal to the axial direction of the lower rotating shaft 92, and the lower rotating shaft 92. And the bevel gear mechanism 120 for converting the rotation of the shaft 61 into the rotation of the shaft 61. Since one end of the shaft 61 is exposed to the outside of the air collecting device 40, the rotation of the shaft 61 is changed to a generator, a compressor, a pump, etc. It can be used as a power source. Thus, by using clean energy obtained by wind power as a power source, for example, environmental pollution can be suppressed.
　また、風力回転装置１１において、外部に露出しているシャフト６１の一端である端部６１ａに、シャフト６１の回転を利用して発電する発電機が連結されている場合、効率的に発電することができる。 Moreover, in the wind power rotation apparatus 11, when the generator 61 which produces electric power using the rotation of the shaft 61 is connected to the end portion 61a which is one end of the shaft 61 exposed to the outside, the electric power can be generated efficiently. Can do.

　風力回転装置１２は、集風装置１１０と回転装置１３０とを備えている。回転装置１３０は、集風装置１１０の内部に収容されている。集風装置１１０の上端には、カバー２が取り付けられている。回転装置１３０は、例えば、カバー２によって支持されている。また、集風装置１１０における排出口３３は、集風装置１１０の上部側に設けられており、上方板３５は設置面と水平となるように形成されている。また、下方板３６は、上下方向に対して、径方向外側から径方向内側に向かう方向に、斜め上方に傾斜している。 The wind power rotating device 12 includes a wind collecting device 110 and a rotating device 130. The rotating device 130 is accommodated in the air collecting device 110. A cover 2 is attached to the upper end of the air collecting device 110. The rotating device 130 is supported by the cover 2, for example. Further, the discharge port 33 in the air collecting device 110 is provided on the upper side of the air collecting device 110, and the upper plate 35 is formed to be horizontal with the installation surface. The lower plate 36 is inclined obliquely upward in the direction from the radially outer side to the radially inner side with respect to the vertical direction.
　仕切り板３４、上方板３５、および下方板３６によって風を取り込む流路が形成されており、流路の断面積は取込口３２から排出口３３に向かうほど小さくなっている。集風装置１１０は、大量の風（平圧空気）を取込口３２から取り込み、仕切り板３４、上方板３５、および下方板３６によって曲げて（絞って）、高密度の高圧風として排出口３３から排出するようになっている。 The flow path for taking in the wind is formed by the partition plate 34, the upper plate 35, and the lower plate 36, and the cross-sectional area of the flow channel becomes smaller toward the discharge port 33 from the intake port 32. The air collecting device 110 takes in a large amount of wind (flat pressure air) from the intake port 32, bends (squeezes) the partition plate 34, the upper plate 35, and the lower plate 36, and discharges it as high-density high-pressure air. 33 is discharged.
　回転装置１３０のファン５１は、回転装置１３０の上部側であって、集風装置１１０における排出口３３の高さに対応する位置に設けられている。これにより、排出口３３から排出された空気がファン５１の羽根５１ｂに次々に当たり、ファン５１が回転する。また、図１６に示すように、回転装置１３０には、ファン５１の回転軸方向に対して直交するように配置されたシャフト６１が連結されている。シャフト６１は、下方板３６に設けられた孔に挿通されており、端部６１ａが風力回転装置１２（集風装置１１０）の外部に露出するように、仕切り板３４における径方向外側の端部に取り付けられている。回転装置１３０は、第２の実施の形態と同様に、回転伝達機構８０および傘歯車機構１２０を備えており、ファン５１の回転に伴ってシャフト６１が回転するようになっている。 The fan 51 of the rotating device 130 is provided on the upper side of the rotating device 130 and at a position corresponding to the height of the discharge port 33 in the air collecting device 110. Thereby, the air discharged from the discharge port 33 sequentially hits the blades 51b of the fan 51, and the fan 51 rotates. As shown in FIG. 16, the rotating device 130 is connected to a shaft 61 arranged so as to be orthogonal to the rotation axis direction of the fan 51. The shaft 61 is inserted into a hole provided in the lower plate 36, and the radially outer end of the partition plate 34 so that the end 61a is exposed to the outside of the wind power rotating device 12 (wind collecting device 110). Is attached. As in the second embodiment, the rotation device 130 includes a rotation transmission mechanism 80 and a bevel gear mechanism 120, and the shaft 61 rotates as the fan 51 rotates.
　以上のように、第３の実施の形態によれば、集風装置１１０が集めた風によって回転するファン５１の回転をシャフト６１の回転に変換するとともに、当該回転を発電機、コンプレッサー、ポンプ等の動力源として利用することができる。このように、風力によって得られたクリーンなエネルギーを動力源とすることで、例えば、環境汚染等を抑制することができる。また、シャフト６１の端部６１ａに発電機が連結されている場合、効率的な発電を実現することができる。 As described above, according to the third embodiment, the rotation of the fan 51 rotated by the wind collected by the air collecting device 110 is converted into the rotation of the shaft 61, and the rotation is converted into a generator, a compressor, a pump, and the like. It can be used as a power source. Thus, by using clean energy obtained by wind power as a power source, for example, environmental pollution can be suppressed. Further, when a generator is connected to the end portion 61a of the shaft 61, efficient power generation can be realized.
　図１７は、図１１で示した回転装置６０の変形例を示す図である。図１７に示すように、ファン５１（回転板５１ａ）の軸方向に対する羽根５１ｂの寸法を幅とした場合、羽根５１ｂは、幅方向の略中央部が、ファン５１の回転方向に向かって突出したＶ字形状であってもよい。 FIG. 17 is a view showing a modification of the rotating device 60 shown in FIG. As shown in FIG. 17, when the dimension of the blade 51 b with respect to the axial direction of the fan 51 (rotating plate 51 a) is defined as the width, the blade 51 b has a substantially central portion in the width direction protruding toward the rotation direction of the fan 51. V shape may be sufficient.
　図１８は、羽根５１ｂに対する風の当たり方について説明するための図である。集風装置４０における８箇所の排出口３３のうち、３箇所の排出口３３から排出された風が羽根５１ｂに当たり、ファン５１が回転する様子を示している。このとき、残り５箇所の排出口３３からは風が排出されないため、ファン５１の回転の妨げとならない。
　ここで、図１７に示すように、ファン５１における回転板５１ａの外周側面を側面Ｗとする。排出口３３から排出された風は、側面Ｗに当たり、回転板５１ａの内部側に侵入することはなくファン５１の回転推進に利用されるようになっている。
　なお、排出口３３から排出され、羽根５１ｂに当たる流体は、風に限定されるものではなく、水であってもよい。 FIG. 18 is a diagram for explaining how the wind strikes the blades 51b. Of the eight outlets 33 in the air collecting device 40, the wind exhausted from three outlets 33 hits the blades 51b, and the fan 51 rotates. At this time, since the wind is not discharged from the remaining five discharge ports 33, the rotation of the fan 51 is not hindered.
Here, as shown in FIG. 17, the outer peripheral side surface of the rotating plate 51 a in the fan 51 is defined as a side surface W. The wind discharged from the discharge port 33 hits the side surface W and does not enter the inner side of the rotating plate 51 a and is used for propulsion of the fan 51.
Note that the fluid discharged from the discharge port 33 and hitting the blades 51b is not limited to the wind but may be water.
