In this state, each of the rotary blades (3 to 5) becomes parallel with a wind direction.

Description

回転翼機構及びこれを用いた発電装置Rotor mechanism and power generator using the same
　　本発明は、流体の運動を利用して回転力を発生させるための回転翼に関するものである。特に本発明は、いわゆる垂直軸型の回転翼機構及びこれを用いた発電装置に関連している。 The present invention relates to a rotating blade for generating a rotational force by using a fluid motion. In particular, the present invention relates to a so-called vertical axis type rotary blade mechanism and a power generation apparatus using the same.
　　従来から、風向に平行な回転軸を持つ風車（いわゆる平行軸型の風車）が、風力発電用として実用化されている。この風車では、基本的には、風向に直交する仮想面内において、巨大な羽根が回転する。このため、以下のような問題点が指摘されている。
・鳥は、上昇気流を探すため、風の下流に向けて飛行する習性がある。すると、風向に垂直な方向に移動する羽根と衝突しやすい。衝突すれば、鳥にも、羽根にも被害を生じる可能性がある。特に、平行軸型の風車では、発電効率を向上させるために、地表から羽根の上端までの高さが１００メートル程度のものがある。このような大型の風車では、被害が顕在化しやすい。
・また、平行軸型の風車では、羽根が巨大であるために、大面積を持つ羽根の先端が比較的に高速で移動することになる。このため、この形式の風車では、風切り音、特に低周波騒音が発生しやすいことが知られている。
・さらに、平行軸型の風車は、高所に回転軸を配置し、回転する巨大な回転翼で風を受けるために、回転翼の支持体と地表面との接続箇所に大きなトルクが作用しやすい。このため、基礎工事や設置工事が大がかりになる傾向にある。
・また、高所に回転翼や回転軸機構をつり上げるには、大きなクレーンが必要であり、この点からも設置工事が大がかりになりやすい。このため、強い風力が発生する尾根に風車を設置するためには、非常に難しい工事が必要となる。また、高所で回転軸や回転翼の保守作業を行うことは容易ではない。
・さらに、平行軸型では、巨大な回転翼があるために、ここに雷が落ちやすく、有効な避雷針設置が難しい。落雷の場合は装置に損傷を受ける可能性がある。 Conventionally, wind turbines having a rotation axis parallel to the wind direction (so-called parallel axis type wind turbines) have been put to practical use for wind power generation. In this windmill, basically, huge blades rotate in a virtual plane orthogonal to the wind direction. For this reason, the following problems have been pointed out.
-Birds have the habit of flying toward the downstream of the wind in order to search for updrafts. Then, it is easy to collide with the blade | wing which moves to a direction perpendicular | vertical to a wind direction. A collision can cause damage to birds and feathers. In particular, a parallel axis type windmill has a height of about 100 meters from the ground surface to the upper end of the blade in order to improve power generation efficiency. In such a large windmill, damage is likely to become obvious.
In addition, in the parallel axis type windmill, since the blades are enormous, the tip of the blade having a large area moves at a relatively high speed. For this reason, it is known that wind noise, particularly low-frequency noise, is likely to occur in this type of windmill.
・ Furthermore, in the parallel axis type wind turbine, the rotating shaft is arranged at a high place and wind is received by a huge rotating blade, so that a large torque acts on the connection between the rotor support and the ground surface. Cheap. For this reason, foundation work and installation work tend to be large.
-In addition, a large crane is required to lift the rotor blades and the rotating shaft mechanism at a high place, and installation work tends to be large in this respect as well. For this reason, in order to install a windmill in the ridge where a strong wind force is generated, a very difficult construction is required. In addition, it is not easy to perform maintenance work on the rotating shaft and rotor blades at a high place.
・ Furthermore, in the parallel shaft type, there are huge rotor blades, so lightning easily falls here, and it is difficult to install an effective lightning rod. In the event of a lightning strike, the equipment may be damaged.
　　このため、風向に直交する回転軸を持つ風車（いわゆる垂直軸型の風車）も提案されている（下記特許文献１参照）。これによれば、前記した課題の多くは解決可能である。また、下記特許文献１の技術では、回転翼が１公転する間に１／２の自転を行う構成となっている。つまり、回転翼の公転周期が、回転翼自体の自転周期の１／２となっている（特許文献１の図４）。このようにすると、公転角０°の位置で回転翼の受風面が風向に直行するとき、公転角１８０°では、回転翼の受風面が、風向とほぼ平行となる。これにより、効率的に風力を回転力に変換することができる。 For this reason, a windmill having a rotation axis orthogonal to the wind direction (so-called vertical axis type windmill) has also been proposed (see Patent Document 1 below). According to this, many of the problems described above can be solved. Moreover, in the technique of the following patent document 1, it is the structure which performs 1/2 autorotation, while a rotary blade revolves once. That is, the revolution period of the rotor blade is ½ of the rotation period of the rotor blade itself (FIG. 4 of Patent Document 1). In this way, when the wind receiving surface of the rotor blade is orthogonal to the wind direction at the revolution angle of 0 °, the wind receiving surface of the rotor blade is substantially parallel to the wind direction at the revolution angle of 180 °. Thereby, wind power can be efficiently converted into rotational force.
　　ところで、風速が過大になると（いわゆる強風時）、回転翼の公転あるいは自転速度が過大となり、支持部品や発電装置が損傷するおそれが生じる。そこで、下記特許文献２では、各回転翼の自転角を、サーボモータによって個別に制御することにより、強風時において、風向と回転翼の受風面とを平行にするようにしている。 By the way, if the wind speed becomes excessive (so-called strong wind), the revolution or rotation speed of the rotor blades becomes excessive, and the support parts and the power generation device may be damaged. Therefore, in Patent Document 2 below, the rotation angle of each rotor blade is individually controlled by a servo motor so that the wind direction and the wind receiving surface of the rotor blade are parallel in a strong wind.
　　しかしながら、サーボモータを用いると、そのための駆動電力が必要となる。このため、風力発電装置においては、一般に、風力を使って発電した電力をサーボモータ用の駆動電力として消費することとなる。すると、発電装置としての発電効率が劣化するという問題を生じる。 However, when a servo motor is used, driving power for that purpose is required. For this reason, in a wind power generator, generally, electric power generated using wind power is consumed as drive power for a servo motor. Then, the problem that the power generation efficiency as a power generation device deteriorates arises.

The rotary blade mechanism of the present embodiment has a so-called vertical axis type structure. Moreover, in this embodiment, gas, ie, a wind force, is used as an example of the fluid for obtaining a rotational force.
　　本実施形態の回転翼機構は、公転軸１と、回転体２と、第１回転翼３と、第２回転翼４と、第３回転翼５と、風向軸６と、固定スプロケット７と、第１可動スプロケット８と、第２可動スプロケット９と、回転力伝達機構１０と、第１かぎ部材１１と、第２かぎ部材１２と、かぎ駆動機構１３とを備えている（図１、図４及び図７参照）。 The rotating blade mechanism of the present embodiment includes a revolution shaft 1, a rotating body 2, a first rotating blade 3, a second rotating blade 4, a third rotating blade 5, a wind direction shaft 6, a fixed sprocket 7, A first movable sprocket 8, a second movable sprocket 9, a rotational force transmission mechanism 10, a first key member 11, a second key member 12, and a key drive mechanism 13 are provided (FIGS. 1 and 4). And FIG. 7).
　　公転軸１は、図１及び図２に示されるように、平面（例えば地盤）上に立設されている。公転軸１の内部には、軸心の方向に延長された空間１ａが形成されている。 The revolution shaft 1 is erected on a plane (for example, the ground) as shown in FIGS. 1 and 2. Inside the revolution shaft 1, a space 1a extending in the direction of the axis is formed.
　　回転体２は、公転軸１を中心として回転可能とされている。具体的には、回転体２は、軸受２ａ（図１参照）を介して公転軸１に取り付けられており、これによって、公転軸１を中心とした回転が可能となっている。回転体２は、各受風翼を支持するための下部支持体２ｂと上部支持体２ｃとを有している（図３参照）。 Rotating body 2 is rotatable around the revolution axis 1. Specifically, the rotating body 2 is attached to the revolution shaft 1 via a bearing 2a (see FIG. 1), and thereby, rotation about the revolution shaft 1 is possible. The rotating body 2 includes a lower support 2b and an upper support 2c for supporting each wind receiving blade (see FIG. 3).
　　第１～第３回転翼３～５は、回転体２に対して、自転できるように取り付けられている（図１及び図４参照）。なお、図１及び図３においては、説明簡略化のため、２枚の回転翼のみが示されている。図３に示すように、各回転翼の下端は、下部支持体２ｂによって、回転可能なように支持されており、各回転翼の上端は、上部支持体２ｃによって、回転可能なように支持されている。なお、各回転翼を回転可能に支持する手段としては、例えば軸受を用いることができる。また、各回転翼を回転体２に取り付けることによって、これらの回転翼は、いずれも、公転軸１を中心として公転できる構成となっている。 The first to third rotor blades 3 to 5 are attached to the rotating body 2 so as to be able to rotate (see FIGS. 1 and 4). In FIG. 1 and FIG. 3, only two rotor blades are shown for simplicity of explanation. As shown in FIG. 3, the lower end of each rotor blade is rotatably supported by the lower support 2b, and the upper end of each rotor blade is rotatably supported by the upper support 2c. ing. In addition, as a means to support each rotary blade rotatably, a bearing can be used, for example. In addition, by attaching each rotor blade to the rotor 2, each of these rotor blades can revolve around the revolution shaft 1.
　　第１～第３回転翼３～５は、第１～第３自転スプロケット３１～５１を備えている（図４参照）。各自転スプロケット３１～５１は、回転力伝達機構１０を介して、風向軸６に取り付けられた各スプロケット７～９（図７参照）に連結されている（後述）。 The first to third rotating blades 3 to 5 are provided with first to third rotating sprockets 31 to 51 (see FIG. 4). The rotating sprockets 31 to 51 are connected to the sprockets 7 to 9 (see FIG. 7) attached to the wind direction shaft 6 via the rotational force transmission mechanism 10 (described later).
　　各回転翼は、図４に示されるように、略平板形状とされている。また、本実施形態においては、各回転翼には、各回転翼の自転における半径方向の両端部（図５において左右方向の端部）において、自転方向とは反対方向に立ち上がる立ち上がり部３２・４２・５２（図４では図示省略されている）がそれぞれ備えられている。 Each rotor blade has a substantially flat plate shape as shown in FIG. Further, in the present embodiment, each rotor blade has a rising portion 32 or 42 that rises in the opposite direction to the rotation direction at both ends in the radial direction during rotation of each rotor blade (the ends in the left-right direction in FIG. 5). 52 (not shown in FIG. 4) are provided.
　　風向軸６は、風力を受けるための風向板６１を備えている（図６参照）。さらに、風向軸６は、公転軸１に対して、風向板６１への風力の方向に従って回転可能とされている。具体的には、風向軸６は、公転軸１の内部に形成された空間１ａの内部に挿入されており、かつ、軸受を介して、この公転軸１に取り付けられている。これにより、風向軸６は、公転軸１に対して回転可能なように支持されている。 The wind direction shaft 6 includes a wind direction plate 61 for receiving wind force (see FIG. 6). Further, the wind direction axis 6 is rotatable with respect to the revolution axis 1 according to the direction of the wind force toward the wind direction plate 61. Specifically, the wind direction shaft 6 is inserted into a space 1a formed inside the revolution shaft 1, and is attached to the revolution shaft 1 via a bearing. Thereby, the wind direction axis | shaft 6 is supported so that rotation with respect to the revolution axis | shaft 1 is possible.
　　固定スプロケット７は、風向軸６の外側面に固定されて、風向軸６の回転に従って回転可能とされている（図７参照）。 The fixed sprocket 7 is fixed to the outer surface of the wind direction shaft 6 and can be rotated according to the rotation of the wind direction shaft 6 (see FIG. 7).
　　第１可動スプロケット８及び第２可動スプロケット９（図７参照）は、風向軸６の外側面に取り付けられており、かつ、風向軸６を中心として回転可能とされている。後述の通り、通常時には、第１及び第２可動スプロケット８及び９は、第１かぎ部材１１によって、風向軸６に対して既定の回転角度を維持するように固定されている。 The first movable sprocket 8 and the second movable sprocket 9 (see FIG. 7) are attached to the outer surface of the wind direction shaft 6 and are rotatable about the wind direction shaft 6. As will be described later, at the normal time, the first and second movable sprockets 8 and 9 are fixed by the first hook member 11 so as to maintain a predetermined rotation angle with respect to the wind direction shaft 6.
　　第１可動スプロケット８の上側及び第２可動スプロケット９の下側には、これらのスプロケットの、軸方向（図８において上下方向）への異動を阻止するストッパ１４ａ及び１４ｂが配置されている。これらのストッパ１４ａ及び１４ｂは、いずれも、風向軸６の外側面に、ビスによって固定されている。ただし、これらのストッパを固定する手段は特に制約されず、例えば接着剤によることも可能である。なお、これらのストッパ１４ａ及び１４ｂ自体は、第１及び第２可動スプロケット８及び９が軸回りに回転することを阻止しないようになっている。 Stoppers 14a and 14b for preventing the movement of these sprockets in the axial direction (vertical direction in FIG. 8) are arranged above the first movable sprocket 8 and below the second movable sprocket 9. These stoppers 14a and 14b are both fixed to the outer surface of the wind direction shaft 6 with screws. However, the means for fixing these stoppers is not particularly limited, and for example, an adhesive may be used. Note that these stoppers 14a and 14b themselves do not prevent the first and second movable sprockets 8 and 9 from rotating about the axis.
　　第１可動スプロケット８は、第１係合部８１と第２係合部８２とを備えている（図７参照）。第１係合部８１と第２係合部８２との位置関係を図９に示す。図示されるように、公転軸１の軸心から第２係合部８２までの距離は、公転軸１の軸心から第１係合部８１までの距離とは異なっている。また、第２係合部８２は、第１係合部８１から図中時計回りで約１２０°の位置に形成されている。第１係合部８１及び第２係合部８２には、後述する第１及び第２かぎ部材１１及び１２の嵌入動作を円滑とするための溝８１ａ及び８２ａが形成されている（図１０参照）。なお、図１０は、第１及び第２かぎ部材が第１及び第２係合部に係合する場合の状態の遷移を概略的に示すものである。 The first movable sprocket 8 includes a first engagement portion 81 and a second engagement portion 82 (see FIG. 7). The positional relationship between the first engagement portion 81 and the second engagement portion 82 is shown in FIG. As shown in the drawing, the distance from the axis of the revolution shaft 1 to the second engagement portion 82 is different from the distance from the axis of the revolution shaft 1 to the first engagement portion 81. Further, the second engaging portion 82 is formed at a position of about 120 ° clockwise from the first engaging portion 81 in the drawing. Grooves 81a and 82a are formed in the first engaging portion 81 and the second engaging portion 82 for smooth insertion operation of the first and second key members 11 and 12, which will be described later (see FIG. 10). ). FIG. 10 schematically shows a state transition when the first and second hook members engage with the first and second engaging portions.
　　第２可動スプロケット９も、第１可動スプロケット８と同様に、第１係合部９１と第２係合部９２とを備えている（図７参照）。なお、後述するように、第２可動スプロケット９の第２係合部９２は、初期状態においては、第１可動スプロケット８の第２係合部８２とは異なる位置（位相角）に配置されているが、理解を容易とするために、図７においては両者を共に図示している。公転軸１の軸心から第２可動スプロケット９の第２係合部９２までの距離は、公転軸１の軸心から第１可動スプロケット８の第２係合部８２までの距離とほぼ等しくされている（図９参照）。なお、図９は、各係合部の位置関係を説明するためのものなので、第１可動スプロケット８の背面側に隠れているはずの係合部も図示している。また、第２可動スプロケット９の第２係合部９２は、第１係合部９１から図中時計回りで約２４０°の位置に形成されている。つまり、第１係合部８１と第１係合部９１とを一致させた状態（図７に示す状態）では、第１係合部８１・９１と第２係合部８２と第２係合部９２との間隔は、いずれも１２０°となっている（図９参照）。さらに、第２可動スプロケット９においても、第１係合部９１及び第２係合部９２に、後述する第１及び第２かぎ部材１１及び１２の嵌入動作を円滑とするための溝９１ａ及び９２ａが形成されている（図１０参照）。 Similarly to the first movable sprocket 8, the second movable sprocket 9 also includes a first engagement portion 91 and a second engagement portion 92 (see FIG. 7). As will be described later, the second engaging portion 92 of the second movable sprocket 9 is disposed at a position (phase angle) different from the second engaging portion 82 of the first movable sprocket 8 in the initial state. However, in order to facilitate understanding, both are shown in FIG. The distance from the axis of the revolution shaft 1 to the second engagement portion 92 of the second movable sprocket 9 is substantially equal to the distance from the axis of the revolution shaft 1 to the second engagement portion 82 of the first movable sprocket 8. (See FIG. 9). Since FIG. 9 is for explaining the positional relationship between the respective engaging portions, the engaging portion that should be hidden behind the first movable sprocket 8 is also illustrated. The second engaging portion 92 of the second movable sprocket 9 is formed at a position of about 240 ° clockwise from the first engaging portion 91 in the drawing. That is, in the state where the first engaging portion 81 and the first engaging portion 91 are matched (the state shown in FIG. 7), the first engaging portions 81 and 91, the second engaging portion 82, and the second engaging portion. The intervals with the part 92 are all 120 ° (see FIG. 9). Further, also in the second movable sprocket 9, grooves 91 a and 92 a for smoothly inserting the first and second hook members 11 and 12 described later into the first engaging portion 91 and the second engaging portion 92. Is formed (see FIG. 10).
　　回転力伝達機構１０は、この実施形態においては、固定／可動スプロケット７，８，９と各自転スプロケット３１～５１との間に掛け渡されたチェーン１０１・１０２・１０３（図４参照）によって構成されている。回転力伝達機構１０のチェーン１０１は、固定スプロケット７と第１回転翼３の第１自転スプロケット３１との間で、同じ方向（図４においては反時計回り）の回転力を伝達することが可能な構成となっている。 In this embodiment, the rotational force transmission mechanism 10 is constituted by chains 101, 102, and 103 (see FIG. 4) spanned between the fixed / movable sprockets 7, 8, and 9 and the respective rotating sprockets 31 to 51. Has been. The chain 101 of the rotational force transmission mechanism 10 can transmit rotational force in the same direction (counterclockwise in FIG. 4) between the fixed sprocket 7 and the first rotating sprocket 31 of the first rotating blade 3. It has become a structure.
　　これにより、回転力伝達機構１０は、第１自転スプロケット３１の公転（例えば図４において反時計回りの公転）によって、公転と逆方向に（例えば図４において時計回りに）、第１自転スプロケット３１を自転させる構成となっている。 As a result, the rotational force transmission mechanism 10 causes the first rotation sprocket 31 to rotate in the opposite direction to the revolution (for example, clockwise in FIG. 4) by the revolution of the first rotation sprocket 31 (for example, counterclockwise rotation in FIG. 4). Is configured to rotate.
　　回転力伝達機構１０のチェーン１０２は、前記したチェーン１０１の場合と同様に、第１可動スプロケット８と第２回転翼４の第２自転スプロケット４１との間で、同じ方向の回転力を伝達する構成となっている。これにより、回転力伝達機構１０は、第２自転スプロケット４１の公転によって、公転と逆方向に、第２自転スプロケット４１を自転させる構成となっている。 As in the case of the chain 101 described above, the chain 102 of the rotational force transmission mechanism 10 transmits rotational force in the same direction between the first movable sprocket 8 and the second rotating sprocket 41 of the second rotary blade 4. It has a configuration. Thereby, the rotational force transmission mechanism 10 is configured to rotate the second rotation sprocket 41 in the direction opposite to the rotation by the revolution of the second rotation sprocket 41.
　　回転力伝達機構１０のチェーン１０３も、前記したチェーン１０１の場合と同様に、第２可動スプロケット９と第３回転翼５の第３自転スプロケット５１との間で、同じ方向の回転力を伝達する構成となっている。これにより、回転力伝達機構１０は、第３自転スプロケット５１の公転によって、公転と逆方向に、第３自転スプロケット５１を自転させる構成となっている。なお、図１では、チェーン１０２及び１０３のうちの一方のみを示す。 The chain 103 of the rotational force transmission mechanism 10 also transmits rotational force in the same direction between the second movable sprocket 9 and the third rotating sprocket 51 of the third rotary blade 5 as in the case of the chain 101 described above. It has a configuration. Thereby, the rotational force transmission mechanism 10 is configured to rotate the third rotation sprocket 51 in the direction opposite to the rotation by the revolution of the third rotation sprocket 51. In FIG. 1, only one of the chains 102 and 103 is shown.
　　第１～第３回転翼３～５は、風向軸６を中心とした１公転の間に１／２回転だけ自転する構成となっている。具体的には、各自転スプロケット３１・４１・５１の歯数は、対応する固定スプロケット７及び可動スプロケット８・９の歯数の２倍とされている。 The first to third rotor blades 3 to 5 are configured to rotate by ½ rotation during one revolution around the wind direction axis 6. Specifically, the number of teeth of each of the rotating sprockets 31, 41, 51 is twice the number of teeth of the corresponding fixed sprocket 7 and movable sprocket 8, 9.
　　第１かぎ部材１１は、第１可動スプロケット８の第１係合部８１と第２可動スプロケット９の第１係合部９１とに、着脱自在に係合して、第１及び第２可動スプロケット８及び９と風向軸６との相対的な回転角度を固定できる構成となっている。 The first hook member 11 is detachably engaged with the first engaging portion 81 of the first movable sprocket 8 and the first engaging portion 91 of the second movable sprocket 9 so that the first and second movable sprockets are engaged. The relative rotation angle between 8 and 9 and the wind direction axis 6 can be fixed.
　　第１かぎ部材１１が第１係合部８１・９１に係合した状態では、第２・第３回転翼４・５が第１回転翼３と同じ公転角度に到達した場合には、第２・第３回転翼４・５の自転角度が、それぞれ、第１回転翼３の自転角度とほぼ等しくなる構成となっている。つまり、各回転翼は、同じ公転角度においては、同じ自転角度となるように設定されている。 In a state where the first hook member 11 is engaged with the first engaging portions 81 and 91, when the second and third rotary blades 4 and 5 reach the same revolution angle as the first rotary blade 3, the second The rotation angles of the third rotor blades 4 and 5 are substantially equal to the rotation angle of the first rotor blade 3, respectively. That is, each rotary blade is set to have the same rotation angle at the same revolution angle.
　　第２かぎ部材１２は、第２係合部８２・９２に、着脱自在に係合して、第１・第２可動スプロケット８・９と風向軸６とを固定できる構成となっている。ここで、第２かぎ部材１２が第２係合部８２・９２に係合した状態では、第２・第３回転翼４・５が第１回転翼３に対して実質的に平行となる構成となっている。この動作については後述する。 The second hook member 12 is configured to be able to detachably engage with the second engaging portions 82 and 92 to fix the first and second movable sprockets 8 and 9 and the wind direction shaft 6. Here, in a state where the second key member 12 is engaged with the second engaging portions 82 and 92, the second and third rotor blades 4 and 5 are substantially parallel to the first rotor blade 3. It has become. This operation will be described later.
　　かぎ駆動機構１３は、通常時に第１かぎ部材１１を第１係合部８１・９１に係合させ、強風時に第２かぎ部材１２を第２係合部８２・９２に係合させる構成となっている。具体的には、かぎ駆動機構１３は、風向軸６の内部に収納された操作部１３１と支持部１３２とを備えている（図７参照）。操作部１３１は、風向軸６の下方に延長されており、適宜な駆動手段（図示せず）あるいは手動により上下動させることができるものとなっている。支持部１３２は、操作部１３１の先端（図７において上端）に取り付けられている。支持部１３２の側面には、第１かぎ部材１１及び第２かぎ部材１２が取り付けられている。なお、支持部１３２の側面に対応する位置においては、風向軸６の側面が、軸方向に沿って開口されており、これによって、かぎ部材１１及び１２の両者が外部に突出し、かつ、必要な範囲で上下動できるようになっている。 The key drive mechanism 13 has a configuration in which the first key member 11 is engaged with the first engaging portions 81 and 91 in a normal state and the second key member 12 is engaged with the second engaging portions 82 and 92 in a strong wind. ing. Specifically, the key drive mechanism 13 includes an operation unit 131 and a support unit 132 housed inside the wind direction shaft 6 (see FIG. 7). The operation part 131 is extended below the wind direction axis 6 and can be moved up and down by appropriate drive means (not shown) or manually. The support part 132 is attached to the tip (upper end in FIG. 7) of the operation part 131. The first key member 11 and the second key member 12 are attached to the side surface of the support portion 132. In addition, in the position corresponding to the side surface of the support part 132, the side surface of the wind direction axis | shaft 6 is opened along the axial direction, and, thereby, both the key members 11 and 12 protrude outside, and required. It can be moved up and down in the range.
　　（本実施形態の動作）
　（通常時の動作）
　つぎに、前記した本実施形態の回転翼機構の動作について説明する。まず、初期状態では、第１かぎ部材１１が二つの第１係合部８１及び９１にそれぞれ嵌入しているものとする（図７の状態）。この状態では、各回転翼の自転角は、図４に示された状態となる。これは、風向軸６の風向板６１が風下を向いた状態である。したがって、回転翼で受けた風力により、図４において反時計方向に回転体２を回転させることができる。したがって、回転体２の回転力を利用する発電機構（図示せず）を用いて、発電を行わせることができる。なお、１公転の間に１／２の自転を行う回転翼機構の動作は既によく知られているので、これについての詳しい説明は省略する。 (Operation of this embodiment)
(Normal operation)
Next, the operation of the rotary blade mechanism of this embodiment will be described. First, in the initial state, it is assumed that the first key member 11 is fitted into the two first engaging portions 81 and 91 (state shown in FIG. 7). In this state, the rotation angle of each rotor blade is in the state shown in FIG. This is a state in which the wind direction plate 61 of the wind direction axis 6 faces downwind. Therefore, the rotating body 2 can be rotated counterclockwise in FIG. 4 by the wind force received by the rotor blades. Therefore, power generation can be performed using a power generation mechanism (not shown) that uses the rotational force of the rotating body 2. In addition, since the operation | movement of the rotary blade mechanism which carries out a half rotation during one revolution is already known well, detailed description about this is abbreviate | omitted.
　　（強風時の動作）
　強風時においては、かぎ駆動機構１３の操作部１３１を操作して、支持部３１２を下方に移動させる。ここで、操作部１３１の操作は、例えば手動によって行われる。もちろん、風力を検知して、モータなどの駆動手段によって操作する構成も可能である。 (Operation in strong wind)
When the wind is strong, the operation unit 131 of the key drive mechanism 13 is operated to move the support unit 312 downward. Here, the operation of the operation unit 131 is performed manually, for example. Of course, the structure which detects wind force and is operated by drive means, such as a motor, is also possible.
　　支持部３１２が下降すると、それに固定されている第１かぎ部材１１及び第２かぎ部材１２も下降する。すると、まず、第１かぎ部材１１が二つの第１係合部８１及び９１から順次抜ける。第１かぎ部材１１が二つの第１係合部８１及び９１から完全に抜けた状態では、第１可動スプロケット８と第２可動スプロケット９とは、風向軸６に対して軸回りに回転可能となる。一方、第２回転翼４と第３回転翼５とは、いずれも、強い風力を受けるので、この風力により自転し、チェーン１０２及び１０３を介して、第１・第２可動スプロケット８・９が風向軸６に対して回転する。 When the support portion 312 is lowered, the first key member 11 and the second key member 12 fixed thereto are also lowered. Then, first, the first key member 11 is sequentially removed from the two first engaging portions 81 and 91. In a state where the first key member 11 is completely removed from the two first engaging portions 81 and 91, the first movable sprocket 8 and the second movable sprocket 9 can rotate about the axis relative to the wind direction axis 6. Become. On the other hand, since both the second rotor blade 4 and the third rotor blade 5 receive strong wind force, they rotate by this wind force, and the first and second movable sprockets 8 and 9 are connected via the chains 102 and 103. It rotates with respect to the wind direction axis 6.
　　ここで、本実施形態では、第１～第３回転翼に立ち上がり部３２～５２を形成したので各回転翼における自転方向の力を高めることができるという利点がある。 Here, in this embodiment, since the rising portions 32 to 52 are formed on the first to third rotor blades, there is an advantage that the force in the rotation direction of each rotor blade can be increased.
　　一方、第２かぎ部材１２は、かぎ駆動機構１３の支持部１３２の下降に伴って下降する。そして、第２かぎ部材１２の先端（図７において下端）が、第１可動スプロケット８の表面（図７において上面）に当接する。すると、第２かぎ部材１２の位置は、回転している第１可動スプロケット８の第２係合部８２の位置に一致する。一致した時点で、第２かぎ部材１２の先端は、第２係合部８２に嵌入し、さらに、第１可動スプロケット８を貫通する。すると、第２かぎ部材１２の先端は、第２可動スプロケット９の上面に当接する（図１０（ｂ））。 On the other hand, the second key member 12 descends as the support portion 132 of the key drive mechanism 13 descends. And the front-end | tip (lower end in FIG. 7) of the 2nd key member 12 contact | abuts on the surface (upper surface in FIG. 7) of the 1st movable sprocket 8. FIG. Then, the position of the second key member 12 coincides with the position of the second engaging portion 82 of the rotating first movable sprocket 8. At the time of matching, the tip of the second key member 12 is fitted into the second engaging portion 82 and further penetrates the first movable sprocket 8. Then, the tip of the second key member 12 comes into contact with the upper surface of the second movable sprocket 9 (FIG. 10B).
　　第２可動スプロケット９も、第１可動スプロケット８と同様に回転しているので、やがて、第２かぎ部材１２の位置と、第２可動スプロケット９における第２係合部９２の位置とが一致する。すると、第２かぎ部材１２の先端は、第２係合部９２に嵌入する（図１０（ｃ））。 Since the second movable sprocket 9 also rotates in the same manner as the first movable sprocket 8, the position of the second key member 12 eventually coincides with the position of the second engaging portion 92 in the second movable sprocket 9. . Then, the tip of the second key member 12 is fitted into the second engaging portion 92 (FIG. 10C).
　　このようにして、第２かぎ部材１２を、二つの第２係合部８２及び９２にそれぞれ係合させることができる。この係合状態では、各可動スプロケット８及び９は、いずれも、風向軸６に対して固定された状態となる。また、第２かぎ部材１２が二つの第２係合部８２及び９２にそれぞれ係合した状態では、図１１に概略的に示したように、第２及び第３回転翼４及び５が、いずれも、第１回転翼３と平行になる。これは、各可動スプロケット８・９が風向軸６に対して自転すると、第２及び第３回転翼４及び５の公転角は不変でも、その自転角が変わるためである。 In this way, the second hook member 12 can be engaged with the two second engaging portions 82 and 92, respectively. In this engaged state, the movable sprockets 8 and 9 are both fixed with respect to the wind direction shaft 6. Further, in a state where the second key member 12 is engaged with the two second engaging portions 82 and 92, respectively, as schematically shown in FIG. Is also parallel to the first rotor blade 3. This is because when the movable sprockets 8 and 9 rotate with respect to the wind direction axis 6, even if the revolution angles of the second and third rotor blades 4 and 5 remain unchanged, the rotation angles change.
　　この状態では、風向軸６の風向板６１と各回転翼とが平行になる。つまり、風向板６１と第１回転翼３とが平行な状態において、前記した動作により、第２回転翼４及び第３回転翼５が、第１回転翼３と平行になる。このように、風向板６１と各回転翼とが平行になるため、強風時において各回転翼が受ける公転力を減少させることができる。これにより、回転体２の過回転を防止することができる。 In this state, the wind direction plate 61 of the wind direction axis 6 and each rotor blade are parallel to each other. That is, in the state where the wind direction plate 61 and the first rotary blade 3 are parallel, the second rotary blade 4 and the third rotary blade 5 are parallel to the first rotary blade 3 by the above-described operation. Thus, since the wind direction plate 61 and each rotary blade become parallel, the revolution force which each rotary blade receives at the time of a strong wind can be reduced. Thereby, the overrotation of the rotary body 2 can be prevented.
　　また、風向板６１と各回転翼が平行な状態において、もし風向きが変わっても、風向板６１の向きに沿うように各回転翼が公転する。また、各回転翼が等間隔で設置されていれば、瞬間的な風向きの変更があっても、各回転翼に作用する公転方向の力の和は、ほぼ零になるという利点もある。 In addition, in a state where the wind direction plate 61 and each rotary blade are parallel, even if the wind direction changes, each rotary blade revolves along the direction of the wind direction plate 61. Further, if the rotor blades are installed at equal intervals, there is an advantage that the sum of the forces in the revolving direction acting on the rotor blades is almost zero even if there is an instantaneous change in the wind direction.
　　前記動作の後、通常時の状態に戻すには、前記と逆の操作を行えばよい。すなわち、かぎ駆動機構１３の操作部１３１を操作して、支持部１３２を上昇させる。すると、前記と逆の動作により、風力による回転力を利用して、第１かぎ部材１１を二つの第１係合部８１及び９１に順次係合させることができる。この状態では、各回転翼の自転角は、図４に示す初期状態に戻る。風力がないときは各回転翼はそのままの状態となるが、この状態ではそもそも発電ができないので、このこと自体は特に問題にならない。また、各回転翼が互いに平行な状態であっても、各翼に設けた立ち上がり部（図５参照）の効果のために、微弱な風によって、初期位置への復帰が可能になる。また、風向きは常時変動するので、その変動に伴い、各翼への回転力を付与することが可能であると考えられる。 In order to return to the normal state after the above operation, the reverse operation is performed. That is, the operation part 131 of the key drive mechanism 13 is operated to raise the support part 132. Then, the first hook member 11 can be sequentially engaged with the two first engaging portions 81 and 91 by utilizing the rotational force of the wind force by the reverse operation to the above. In this state, the rotation angle of each rotor blade returns to the initial state shown in FIG. When there is no wind power, each rotor blade is left as it is, but in this state, power generation is not possible in the first place, so this is not a problem in itself. Even if the rotary blades are parallel to each other, the initial position can be restored by a weak wind due to the effect of the rising portions (see FIG. 5) provided on the blades. Further, since the wind direction constantly fluctuates, it is considered that a rotational force can be applied to each blade along with the fluctuation.
　　ここで、本実施形態では、かぎ駆動機構１３を上下動させるだけで各回転翼を平行にできるので、仮にかぎ駆動機構１３を電力により駆動した場合でも、消費電力が少なくてすむ。このため、この回転翼機構を用いた発電装置において、発電効率の低下が少ないという利点がある。 Here, in the present embodiment, since the rotary blades can be made parallel only by moving the key drive mechanism 13 up and down, even when the key drive mechanism 13 is driven by electric power, power consumption can be reduced. For this reason, in the electric power generating apparatus using this rotary blade mechanism, there exists an advantage that there is little fall of power generation efficiency.
　次に、図１２～図１４を参照して、本発明の第２実施形態に係る回転翼機構を説明する。第２実施形態の説明においては、前記した第１実施形態と基本的に共通する部材については、同一符号を用いることによって、説明を簡略化する。前記した第１実施形態では、合計３枚の回転翼を用いていたが、第２実施形態では、合計８枚の回転翼を用いる点で、第１実施形態とは異なる。ただし、両実施形態における動作原理は同じである。 Next, a rotating blade mechanism according to a second embodiment of the present invention will be described with reference to FIGS. In description of 2nd Embodiment, description is simplified by using the same code | symbol about the member fundamentally common with above-described 1st Embodiment. In the first embodiment described above, a total of three rotor blades are used. However, the second embodiment is different from the first embodiment in that a total of eight rotor blades are used. However, the operating principle in both embodiments is the same.
　すなわち、第２実施形態の回転翼機構は、第１～第８の回転翼２１１～２１８を備えており、これらの回転翼には、第１実施形態の場合と同様に、それぞれを自転させるための自転スプロケット（図示せず）が取り付けられている。 That is, the rotary blade mechanism of the second embodiment includes first to eighth rotary blades 211 to 218, and these rotary blades rotate in the same manner as in the first embodiment. A rotating sprocket (not shown) is attached.
　一方、風向軸６には、第１実施形態と同様に、固定スプロケット及び可動スプロケットが取り付けられているが、第２実施形態では、回転翼の枚数に対応して、８個のスプロケットが用いられている。すなわち、第２実施形態における風向軸６には、固定スプロケット２２０と、第１～第７可動スプロケット２３１～２３７とが取り付けられている。 On the other hand, a fixed sprocket and a movable sprocket are attached to the wind direction shaft 6 as in the first embodiment, but in the second embodiment, eight sprockets are used corresponding to the number of rotor blades. ing. That is, a fixed sprocket 220 and first to seventh movable sprockets 231 to 237 are attached to the wind direction shaft 6 in the second embodiment.
　固定スプロケット２２０には、固定スプロケット７の場合と同様に、第１係合部２２１と第２係合部２２２とが形成されている（図１３～図１４参照）。 The fixed sprocket 220 is formed with a first engaging portion 221 and a second engaging portion 222 as in the case of the fixed sprocket 7 (see FIGS. 13 to 14).
　さらに、第１～第７可動スプロケット２３１～２３７においても、第１係合部２３１１～２３７１と第２係合部２３１２～２３７２とが形成されている（図１３～図１４参照）。なお、図１４では、各係合部の位置関係を示すために、本来は隠れているはずの係合部も実線で示している。 Furthermore, the first to seventh movable sprockets 231 to 237 are also formed with first engaging portions 2311 to 2371 and second engaging portions 2312 to 2372 (see FIGS. 13 to 14). In FIG. 14, in order to show the positional relationship between the engaging portions, the engaging portions that should have been hidden are also shown by solid lines.
　さらに、第１実施形態では、一つのかぎ駆動機構１３を用いていたが、第２実施形態では、このかぎ駆動機構を分割して、第１かぎ駆動機構３１３１と第２かぎ駆動機構３１３２とを用いる。第１実施形態の場合と同様に、第１かぎ駆動機構３１３１には、第１かぎ部材１１が取り付けられており、第２かぎ駆動機構３１３２には、第２かぎ部材１２が取り付けられている（図１２参照）。 Furthermore, in the first embodiment, one key drive mechanism 13 is used. However, in the second embodiment, this key drive mechanism is divided into a first key drive mechanism 3131 and a second key drive mechanism 3132. Use. As in the case of the first embodiment, the first key drive mechanism 3131 is attached with the first key member 11, and the second key drive mechanism 3132 is attached with the second key member 12 ( (See FIG. 12).
　つぎに、第２実施形態における回転翼機構の動作を説明する。 Next, the operation of the rotary blade mechanism in the second embodiment will be described.
　（８枚の回転翼を使用）
　弱風時、例えば15m/s以下の風速のときは、８枚の回転翼を動作状態とする。この状態の各回転翼の状態を、図１２（ａ）に示す。この状態では、第１かぎ駆動機構３１３１の第１かぎ部材１１が、固定スプロケット２２０の第１係合部２２１と、第１～第７可動スプロケット２３１～２３７の第１係合部２３１１～２３７１に嵌入している。これにより、各回転翼について、同じ公転角であれば同じ自転角となるように動作させることができる。 (Uses 8 rotor blades)
When the wind is weak, for example, when the wind speed is 15 m / s or less, the eight rotor blades are set in an operating state. The state of each rotor blade in this state is shown in FIG. In this state, the first key member 11 of the first key driving mechanism 3131 is engaged with the first engaging portion 221 of the fixed sprocket 220 and the first engaging portions 2311 to 2371 of the first to seventh movable sprockets 231 to 237. It is inserted. Thereby, about each rotary blade, if it is the same revolution angle, it can be operated so that it may become the same autorotation angle.
　（４枚の回転翼を使用）
　図１２（ａ）の場合よりも風速が高い時、例えば15m/s～19m/sの風速のときは、４枚の回転翼２１５～２１８を動作状態とする。この状態の各回転翼の状態を、図１２（ｂ）に示す。この状態では、第１かぎ駆動機構３１３１の第１かぎ部材１１が、第１～第４可動スプロケット２３１～２３４の第１係合部２３１１～２３４１から外れている。そして、その代わりに、第２かぎ駆動機構３１３２の第２かぎ部材１２が、第１～第４可動スプロケット２３１～２３４の第２係合部２３１２～２３４２に嵌入している。これにより、第１～第４回転翼については、風向と平行とし、それ以外の４枚の回転翼については、同じ公転角であれば同じ自転角となるように動作させることができる（図１２（ｂ）参照）。第２かぎ部材１２が第２係合部に嵌入する動作は、前記した第１実施形態と同様なので、詳しい説明は省略する（図１３（ｂ）参照）。また、５枚～７枚の回転翼を動作させることも可能であるが、その場合の動作は、前記から理解可能なので、詳しい説明は省略する。 (Uses 4 rotor blades)
When the wind speed is higher than in the case of FIG. 12A, for example, when the wind speed is 15 m / s to 19 m / s, the four rotor blades 215 to 218 are set in an operating state. The state of each rotor blade in this state is shown in FIG. In this state, the first key member 11 of the first key drive mechanism 3131 is disengaged from the first engaging portions 2311 to 2341 of the first to fourth movable sprockets 231 to 234. Instead, the second key member 12 of the second key driving mechanism 3132 is fitted into the second engaging portions 2312 to 2342 of the first to fourth movable sprockets 231 to 234. As a result, the first to fourth rotor blades can be operated in parallel with the wind direction, and the other four rotor blades can be operated to have the same rotation angle at the same revolution angle (FIG. 12). (See (b)). The operation in which the second key member 12 is fitted into the second engaging portion is the same as in the first embodiment described above, and a detailed description thereof will be omitted (see FIG. 13B). It is also possible to operate 5 to 7 rotating blades, but since the operation in that case can be understood from the above, detailed description thereof will be omitted.
　（２枚の回転翼を使用）
　図１２（ｂ）の場合よりも風速が高い時、例えば19m/s～24m/sの風速のときは、２枚の回転翼２１７及び２１８を動作状態とする。この状態の各回転翼の状態を、図１２（ｃ）に示す。この状態では、第１かぎ駆動機構３１３１の第１かぎ部材１１が、第１～第６可動スプロケット２３１～２３６の第１係合部２３１１～２３６１から外れている。そして、その代わりに、第２かぎ駆動機構３１３２の第２かぎ部材１２が、第１～第６可動スプロケット２３１～２３６の第２係合部２３１２～２３６２に嵌入している。これにより、第１～第６回転翼については、風向と平行とし、それ以外の２枚の回転翼については、同じ公転角であれば同じ自転角となるように動作させることができる（図１２（ｃ）参照）。第２かぎ部材１２が第２係合部に嵌入する動作は、前記した第１実施形態と同様なので、詳しい説明は省略する。また、３枚の回転翼を動作させることも可能であるが、その場合の動作は、前記から理解可能なので、詳しい説明は省略する。 (Uses two rotor blades)
When the wind speed is higher than in the case of FIG. 12B, for example, when the wind speed is 19 m / s to 24 m / s, the two rotor blades 217 and 218 are set in an operating state. The state of each rotor blade in this state is shown in FIG. In this state, the first key member 11 of the first key drive mechanism 3131 is disengaged from the first engaging portions 2311 to 2361 of the first to sixth movable sprockets 231 to 236. Instead, the second key member 12 of the second key driving mechanism 3132 is fitted into the second engaging portions 2312 to 2362 of the first to sixth movable sprockets 231 to 236. Thus, the first to sixth rotor blades can be operated in parallel with the wind direction, and the other two rotor blades can be operated to have the same rotation angle if they have the same revolution angle (FIG. 12). (See (c)). Since the operation | movement in which the 2nd key member 12 inserts in a 2nd engaging part is the same as that of above-described 1st Embodiment, detailed description is abbreviate | omitted. It is also possible to operate three rotor blades, but since the operation in that case can be understood from the above, detailed description will be omitted.
　（強風時）
　図１２（ｃ）の場合よりも風速がさらに高い時、例えば24m/s以上の風速のときは、全ての回転翼を非動作状態とする。この状態の各回転翼の状態を、図１２（ｄ）に示す。この状態では、第１かぎ駆動機構３１３１の第１かぎ部材１１が、第１～第７可動スプロケット２３１～２３７の第１係合部２３１１～２３７１と固定スプロケット２２０の第１係合部２２１とから外れている。そして、その代わりに、第２かぎ駆動機構３１３２の第２かぎ部材１２が、第１～第７可動スプロケット２３１～２３７の第２係合部２３１２～２３７２と、固定スプロケット２２０の第２係合部２２２とに嵌入している。これにより、第１～第８回転翼を、風向に平行な状態とすることができる（図１２（ｄ）参照）。第２かぎ部材１２が第２係合部に嵌入する動作は、前記した第１実施形態と同様なので、詳しい説明は省略する（図１３（ａ）及び（ｃ）参照）。また、１枚の回転翼を動作させることも可能であるが、その場合の動作は、前記から理解可能なので、詳しい説明は省略する。 (In strong wind)
When the wind speed is higher than in the case of FIG. 12C, for example, when the wind speed is 24 m / s or more, all the rotor blades are set in a non-operating state. The state of each rotor blade in this state is shown in FIG. In this state, the first key member 11 of the first key driving mechanism 3131 is moved from the first engaging portions 2311 to 2371 of the first to seventh movable sprockets 231 to 237 and the first engaging portion 221 of the fixed sprocket 220. It is off. Instead, the second key member 12 of the second key drive mechanism 3132 includes the second engaging portions 2312 to 2372 of the first to seventh movable sprockets 231 to 237 and the second engaging portion of the fixed sprocket 220. 222. As a result, the first to eighth rotor blades can be in a state parallel to the wind direction (see FIG. 12D). Since the operation of fitting the second key member 12 into the second engaging portion is the same as that in the first embodiment described above, detailed description thereof will be omitted (see FIGS. 13A and 13C). Further, although it is possible to operate one rotary blade, the operation in that case can be understood from the above description, and detailed description thereof will be omitted.
　第２実施形態における他の構成及び利点は、第１実施形態と同様なので、これ以上の説明は省略する。 Since other configurations and advantages in the second embodiment are the same as those in the first embodiment, further explanation is omitted.
　（第３実施形態）
　次に、図１５を参照して、第３実施形態に係る回転翼機構を説明する。第３実施形態の説明においては、前記した第１実施形態と基本的に共通する部材については、同一符号を用いることによって、説明を簡略化する。前記した第１実施形態では、第１かぎ部材１１と第２かぎ部材１２とを、一つのかぎ駆動機構１３によって駆動していた。これに対して、第３実施形態では、第１かぎ部材１１を第１かぎ駆動機構３１３１で駆動し、第２かぎ部材１２を第２かぎ駆動機構３１３２で駆動する構成としている。図示の例では、第１かぎ部材１１を第１係合部８１及び９１から外した後、第２かぎ部材１２を第２係合部８２及び９２に順次嵌入する。これにより、第１実施形態の場合と同様の動作が可能となる。 (Third embodiment)
Next, a rotating blade mechanism according to the third embodiment will be described with reference to FIG. In the description of the third embodiment, the same reference numerals are used for members that are basically the same as those in the first embodiment described above, thereby simplifying the description. In the first embodiment described above, the first key member 11 and the second key member 12 are driven by one key drive mechanism 13. On the other hand, in the third embodiment, the first key member 11 is driven by the first key driving mechanism 3131 and the second key member 12 is driven by the second key driving mechanism 3132. In the illustrated example, after the first key member 11 is removed from the first engaging portions 81 and 91, the second key member 12 is sequentially fitted into the second engaging portions 82 and 92. As a result, the same operation as in the first embodiment is possible.
　第３実施形態における他の構成及び利点は、第１実施形態と同様なので、これ以上の説明は省略する。 Since other configurations and advantages in the third embodiment are the same as those in the first embodiment, further explanation is omitted.
　（第４実施形態）
　次に、図１６を参照して、第４実施形態に係る回転翼機構を説明する。第４実施形態の説明においては、前記した第１実施形態と基本的に共通する部材については、同一符号を用いることによって、説明を簡略化する。第４実施形態の回転翼機構は、風向軸６を支持するための支持枠４００を備えている。支持枠４００は、基体４０１と支柱４０２とから構成されている。基体４０１と風向軸６との接続箇所には、風向軸６を回転可能なように支持するためのベアリングが取り付けられている。この実施形態では、支持枠４００を設けたので、強風時において回転翼機構の損傷を防ぐことができる。 (Fourth embodiment)
Next, a rotating blade mechanism according to the fourth embodiment will be described with reference to FIG. In the description of the fourth embodiment, the same reference numerals are used for members that are basically the same as those in the first embodiment described above, thereby simplifying the description. The rotary blade mechanism of the fourth embodiment includes a support frame 400 for supporting the wind direction shaft 6. The support frame 400 includes a base body 401 and a support column 402. A bearing for supporting the wind direction shaft 6 so as to be rotatable is attached to a connection portion between the base body 401 and the wind direction shaft 6. In this embodiment, since the support frame 400 is provided, it is possible to prevent damage to the rotary blade mechanism during strong winds.
　第４実施形態における他の構成及び利点は、第１実施形態と同様なので、これ以上の説明は省略する。 Since other configurations and advantages in the fourth embodiment are the same as those in the first embodiment, further description is omitted.
　（第５実施形態）
　次に、図１７～２０を参照して、第５実施形態に係る回転翼機構を説明する。第５実施形態の説明においては、前記した第１実施形態と基本的に共通する部材については、同一符号を用いることによって、説明を簡略化する。第５実施形態の回転翼機構は、回転翼を通過した気流の排出効率を高めるための上方排気機構５００を備えている。 (Fifth embodiment)
Next, a rotating blade mechanism according to a fifth embodiment will be described with reference to FIGS. In the description of the fifth embodiment, the same reference numerals are used for members that are basically the same as those in the first embodiment described above, thereby simplifying the description. The rotary blade mechanism of the fifth embodiment includes an upper exhaust mechanism 500 for improving the discharge efficiency of the airflow that has passed through the rotary blade.
　上方排気機構５００は、６本の支柱５１０と、上部レール５２０と、案内板５３０と、回転枠５４０とを備えている。 The upper exhaust mechanism 500 includes six struts 510, an upper rail 520, a guide plate 530, and a rotating frame 540.
　支柱５１０は、断面円形とされており（図２０参照）、回転体２の外側に配置されている。なお、図１７には、支柱５１０を支持する補助支柱５１１も記載されているが、図２０では補助支柱の記載を省略している。 The column 510 has a circular cross section (see FIG. 20), and is disposed outside the rotating body 2. In FIG. 17, auxiliary struts 511 that support the struts 510 are also illustrated, but in FIG. 20, the description of the auxiliary struts is omitted.
　上部レール５２０は、円環状とされており、支柱５１０の上端に取り付けられている（図１８参照）。 The upper rail 520 has an annular shape and is attached to the upper end of the column 510 (see FIG. 18).
　案内板５３０は、下に凸とされた円錐台形状とされており、その上端が上部レール５２０に接続されている。 The guide plate 530 has a truncated cone shape that is convex downward, and its upper end is connected to the upper rail 520.
　回転枠５４０は、風向軸６の風向板６１に取り付けられており、この風向板６１と一緒に回動するように構成されている。具体的には、回転枠５４０は、上面板５４１と、側面板５４２及び５４３とから概略構成されている。また、回転枠５４０の内部には、気流を通過させるための通風路５４４が形成されている。 The rotation frame 540 is attached to the wind direction plate 61 of the wind direction shaft 6 and is configured to rotate together with the wind direction plate 61. Specifically, the rotating frame 540 is generally configured by an upper surface plate 541 and side surface plates 542 and 543. In addition, a ventilation path 544 for allowing airflow to pass therethrough is formed inside the rotary frame 540.
　上面板５４１は、図１８に示すように、略扇形とされており、かつ、風向板６１に固定されている。上面板５４１により、通風路５４４の上面が規定されている。 As shown in FIG. 18, the top plate 541 has a substantially fan shape and is fixed to the wind direction plate 61. The upper surface plate 541 defines the upper surface of the ventilation path 544.
　側面板５４２及び５４３は、上面板５４１の側部に接続されており、通風路５４４の側面を規定している。 The side plates 542 and 543 are connected to the side portion of the top plate 541 and define the side surface of the ventilation path 544.
　さらに、側面板５４２及び５４３の下部には、ローラ５４２ａ及び５４３ａが取り付けられている。ローラ５４２ａ及び５４３ａは、上部レール５２０の上面を走行可能となっており、これによって、回転枠５４０が風向板６１と一緒に移動できるようになっている。 Furthermore, rollers 542a and 543a are attached to the lower portions of the side plates 542 and 543. The rollers 542 a and 543 a can run on the upper surface of the upper rail 520, so that the rotating frame 540 can move together with the wind direction plate 61.
　第５実施形態の回転翼機構によれば、回転体２の上部近傍を通過する気流の一部は、案内板５３０によって上方に案内され、さらには、回転枠５４０の通風路５４４を通って下流に移動できる。このように、本実施形態では、風向板６１の向き（つまり気流の下流側への向き）に気流を流すことができる。これにより、回転翼周辺での気流の流れを円滑にすることができ、その結果、気流の流れを回転翼によって効率的に受けることができる。 According to the rotary blade mechanism of the fifth embodiment, a part of the airflow passing through the vicinity of the upper portion of the rotating body 2 is guided upward by the guide plate 530, and further downstream through the ventilation path 544 of the rotary frame 540. Can move to. Thus, in the present embodiment, the airflow can flow in the direction of the wind direction plate 61 (that is, the direction toward the downstream side of the airflow). Thereby, the flow of the airflow around the rotor blade can be made smooth, and as a result, the airflow can be efficiently received by the rotor blade.
　次に、図２１～２２を参照して、第５実施形態に係る回転翼機構をさらに補足して説明する。 Next, with reference to FIGS. 21 to 22, the rotary blade mechanism according to the fifth embodiment will be further described.
　第２実施形態においては、風向軸６の周囲に固定スプロケット２２０と第１～第７可動スプロケット２３１～２３７とを配置した。これに対して、第６実施形態の回転翼機構では、風向軸６の外側にこれらのスプロケットを配置し、ギヤ機構を介して風向軸６に各スプロケットを取り付けた。 In the second embodiment, the fixed sprocket 220 and the first to seventh movable sprockets 231 to 237 are arranged around the wind direction axis 6. In contrast, in the rotary blade mechanism of the sixth embodiment, these sprockets are arranged outside the wind direction shaft 6 and each sprocket is attached to the wind direction shaft 6 via a gear mechanism.
　具体的には、この第５実施形態では、固定スプロケット２２０と第１～第７可動スプロケット２３１～２３７とが、回転軸６００に対して、これに対して自転可能なように取り付けられている。そして、各スプロケットの位置は、第１かぎ部材１１と第２かぎ部材１２とによって規定されている。回転軸６００は、ベベルギヤを用いた回転伝達機構６５０によって風向軸６に接続されている。 Specifically, in the fifth embodiment, the fixed sprocket 220 and the first to seventh movable sprockets 231 to 237 are attached to the rotating shaft 600 so as to be able to rotate relative thereto. The position of each sprocket is defined by the first key member 11 and the second key member 12. The rotation shaft 600 is connected to the wind direction shaft 6 by a rotation transmission mechanism 650 using a bevel gear.
　これにより、第５実施形態では、第２実施形態と同様の動作を実現することができる。また、第５実施形態では、ベベルギヤ間の減速比を調節することによって、各回転翼が１公転する間に１／２自転する構成を実現することができる。すなわち、この実施形態では、固定スプロケット２２０と第１～第７可動スプロケット２３１～２３７とを、各自転スプロケットと同じピッチ円半径とすることができ、これのため、固定スプロケット２２０と第１～第７可動スプロケット２３１～２３７とを小型化できるという利点もある。 Thereby, in the fifth embodiment, the same operation as in the second embodiment can be realized. Further, in the fifth embodiment, by adjusting the reduction ratio between the bevel gears, it is possible to realize a configuration in which each rotary blade rotates by half during one revolution. That is, in this embodiment, the fixed sprocket 220 and the first to seventh movable sprockets 231 to 237 can have the same pitch circle radius as that of the respective rotating sprockets. There is also an advantage that the 7 movable sprockets 231 to 237 can be downsized.
　本実施形態では、地盤上に立設された台座１００により回転枠２が回転自在に支持されており、仮想的な公転軸１（図２１及び図２２参照）を中心として各翼が公転する。 In this embodiment, the rotary frame 2 is rotatably supported by a pedestal 100 erected on the ground, and each wing revolves around a virtual revolution shaft 1 (see FIGS. 21 and 22).
　（第６実施形態）
　次に、図２３～２８を参照して、第６実施形態に係る回転翼機構を説明する。第６実施形態の説明においては、前記した第１実施形態と基本的に共通する部材については、同一符号を用いることによって、説明を簡略化する。 (Sixth embodiment)
Next, a rotating blade mechanism according to a sixth embodiment will be described with reference to FIGS. In the description of the sixth embodiment, the same reference numerals are used for members that are basically the same as those in the first embodiment described above, thereby simplifying the description.
　第６実施形態の回転翼機構は、回転体２の周囲に、側方排気機構７００を備えている。具体的には、側方排気機構７００は、６枚の導風翼７１０と、駆動機構７２０（図２６）とを備えている。 The rotary blade mechanism of the sixth embodiment includes a side exhaust mechanism 700 around the rotary body 2. Specifically, the side exhaust mechanism 700 includes six air guide blades 710 and a drive mechanism 720 (FIG. 26).
　各導風翼７１０は、いずれも、薄肉板状の本体７１１と、回転軸７１２とを備えている。本体７１１は、図２８に拡大して示すように、回転軸７１２に対して偏心する位置に取り付けられている。回転軸７１２の上端は、第４実施形態で説明したものと同様な支持枠４００によって、回転可能なように支持されている。また、回転軸７１２の下端も、適宜な土台によって、回転可能なように支持されている。 Each of the air guide blades 710 includes a thin plate-like main body 711 and a rotating shaft 712. The main body 711 is attached at a position eccentric with respect to the rotation shaft 712 as shown in an enlarged view in FIG. The upper end of the rotating shaft 712 is rotatably supported by a support frame 400 similar to that described in the fourth embodiment. Moreover, the lower end of the rotating shaft 712 is also rotatably supported by an appropriate base.
　駆動機構７２０は、モータ７２１と、伝動機構７２２と、クラッチ機構７２３と、ベベルギヤ７２４とを備えている（図２６参照）。 The drive mechanism 720 includes a motor 721, a transmission mechanism 722, a clutch mechanism 723, and a bevel gear 724 (see FIG. 26).
　モータ７２１は、図示しない制御手段によって、所定角度で回転するように制御されるようになっている。 The motor 721 is controlled to rotate at a predetermined angle by a control means (not shown).
　伝動機構７２２は、クラッチ機構７２３及びベベルギヤ７２４を介して、モータ７２１の回転力を導風翼７１０の回転軸７１２に伝えるための機構である。伝動機構７２２の具体的構成は特に制約されないが、例えばウォームギヤとウォームホイールとの組み合わせを用いることができる。 The transmission mechanism 722 is a mechanism for transmitting the rotational force of the motor 721 to the rotating shaft 712 of the wind guide blade 710 via the clutch mechanism 723 and the bevel gear 724. Although the specific structure of the transmission mechanism 722 is not particularly limited, for example, a combination of a worm gear and a worm wheel can be used.
　クラッチ機構７２３は、伝動機構７２２の途中に取り付けられている。クラッチ機構７２３の断続動作は、適宜な制御機構により行うことができる。 The clutch mechanism 723 is attached in the middle of the transmission mechanism 722. The intermittent operation of the clutch mechanism 723 can be performed by an appropriate control mechanism.
　ベベルギヤ７２４は、回転軸７１２に取り付けられたベベルギヤと噛みあっており、回転軸７１２を回転させることができるようになっている。 The bevel gear 724 is meshed with a bevel gear attached to the rotation shaft 712 so that the rotation shaft 712 can be rotated.
　第６実施形態の回転翼機構によれば、モータ７２１によって導風翼７１０を適宜な角度に制御することによって、回転体２の側方を通過する気流を効率よく流すことができる。これにより、本実施形態では、各回転翼における受風効率を向上させることができる。 According to the rotary blade mechanism of the sixth embodiment, by controlling the air guide blade 710 to an appropriate angle by the motor 721, the airflow passing through the side of the rotating body 2 can be efficiently flowed. Thereby, in this embodiment, the wind receiving efficiency in each rotary blade can be improved.
　また、強風時には、クラッチ機構７２３を切断状態とすることによって、導風翼７１０を回転自由とすることができる。導風翼７１０の本体７１１は、回転軸７１２に対して偏心した状態で取り付けられているので、クラッチ機構７２３を切断状態としたときには、風力によって、導風翼７１０の本体７１１を風向に沿って配置することができる。したがって、本実施形態では、強風時において導風翼７１０が損傷する可能性を低減することができる。 Further, when the wind is strong, the wind guide blade 710 can be freely rotated by setting the clutch mechanism 723 to the disconnected state. Since the main body 711 of the wind guide blade 710 is attached in an eccentric state with respect to the rotating shaft 712, when the clutch mechanism 723 is in a disconnected state, the main body 711 of the wind guide blade 710 is moved along the wind direction by wind force. Can be arranged. Therefore, in the present embodiment, it is possible to reduce the possibility of the wind guide blades 710 being damaged during a strong wind.
　第６実施形態における他の構成及び利点は、第１実施形態と同様なので、これ以上の説明は省略する。 Since other configurations and advantages in the sixth embodiment are the same as those in the first embodiment, further explanation is omitted.
　　なお、本発明は、前記した実施の形態に限定されるものではなく、本発明の要旨を逸脱しない範囲内において種々の変更を加え得るものである。例えば、前記した実施形態では、特定枚数の回転翼を用いたが、それ以外の適宜の数とすることができる。この場合、可動スプロケットの数は、回転翼の数に応じて設定される。また、各可動スプロケットに形成される第２係合部の角度関係は、各回転翼の配置状態に応じて、前記した動作が可能なように設定される。 The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present invention. For example, in the above-described embodiment, a specific number of rotor blades is used, but any other appropriate number can be used. In this case, the number of movable sprockets is set according to the number of rotor blades. Further, the angular relationship of the second engaging portions formed on each movable sprocket is set so that the above-described operation is possible according to the arrangement state of each rotor blade.
　　また、前記した実施形態では、流体として風力を例示したが、水力など、他の流体の流れを用いることは可能である。 In the above-described embodiment, wind power is exemplified as the fluid. However, it is possible to use other fluid flows such as hydraulic power.
