Claim 8, windmill to rotate about a horizontal central axis, it rotates with the wind coming to the side of the central axis, yet has a plurality of said wind turbine, to drive the the generator by the rotation power of the wind turbine When generating wind power,
The windmill has a wall plate that is in a state of being erected on both sides of the blade toward the windward when a blade having a certain width stands vertically at a position shifted from the center of the central axis toward the leeward side. In addition, one wall plate is attached to the central shaft between the inner end and the outer end of the blade, and the inner end of the blade and the outer periphery of the central shaft are spaced apart and received. By making a deep groove shape so that the wind escapes to the inner end and the outer end of the blade,
A wind power how to characterized by rotating the windmill against the inner end of the wind immediately succeeding vanes escaped from the inner end side of the vane.

請求項１に記載のように、水平の中心軸の回りに回転する風車は、前記中心軸の中心から風下寄りにずれた位置で一定幅の羽根が鉛直に立った時点で風上に向かって前記羽根の両側に立設された状態となる壁板を有し、前記羽根の内端と外端との間で片方の壁板を前記中心軸に取付け、しかも前記羽根の内端と前記中心軸の外周との間は離れて開いた構成としてあるので、段落「0028」に記載のように、壁板１６、１７が有るので、羽根１４を駆動した後は外周側と内周側に逃げるが、内周側に逃げた風は一つ先の羽根１４の内端に矢印のように当たって回転させるので、風車の回転がより円滑に行われる。
従って、羽根１４は、通常のように中心軸２、２′に直接に取付けるのでなく、片方の壁板16のみを中心軸２、２′まで延ばして取付けてあり、羽根１４や他方の壁板17には、中心軸２、２′との間に隙間１５ができ、風が通過できる。
As described in claim 1, the wind turbine which rotates about a horizontal central axis, the blade having a constant width at a position shifted downwind toward the center of the center axis upwind when standing vertically A wall plate that is erected on both sides of the blade, and one wall plate is attached to the central axis between the inner end and the outer end of the blade, and the inner end of the blade and the center Since it is configured to be spaced apart from the outer periphery of the shaft, there are wall plates 16 and 17 as described in the paragraph “0028”. Therefore, after the blades 14 are driven, they escape to the outer peripheral side and the inner peripheral side. However, since the wind that has escaped to the inner peripheral side hits the inner end of the immediately preceding blade 14 as shown by the arrow, the windmill rotates more smoothly.
Accordingly, the blade 14 is not directly attached to the central shafts 2 and 2 'as usual, but only one wall plate 16 is extended to the central shafts 2 and 2', and the blade 14 and the other wall plate are attached. In 17, a gap 15 is formed between the central axes 2 and 2 ′, and wind can pass therethrough.

請求項２によると、前記風車に対する向かい風が前記風車に対する追い風となるような登り坂状のガイドを風車の風上に設けてあるので、向かい風も有効に追い風として作用でき、風力を発電に効果的に変換できる。 According to the second aspect of the present invention, since the uphill-shaped guide is provided on the wind turbine so that the head wind against the wind turbine becomes a tail wind against the wind turbine, the head wind can effectively act as a tail wind, and wind power is effective for power generation. Can be converted to

請求項３によると、前記風車に対する追い風が常に到来するように風向追尾装置で検出し、この風向追尾装置の動きに連動して風車の受風面が常に風上に向くように前記中心軸や登り坂状のガイドも鉛直軸を中心に回動するので、常に追い風で効果的に風車を回転させ、また向かい風も登り坂面にガイドされ、追い風として風車を回転させ、常にパワーの大きな発電が可能となる。 According to the third aspect, the wind direction tracking device detects that the tail wind with respect to the wind turbine always arrives, and the central axis and the wind turbine so that the wind receiving surface of the wind turbine always faces the windward in conjunction with the movement of the wind direction tracking device. Since the uphill guide also rotates around the vertical axis, the windmill always rotates effectively with the tailwind, and the headwind also guides the uphill slope and rotates the windmill as the tailwind, which always generates high power. It becomes possible.

請求項４によると、段落「0027」に記載のように、風を受ける羽根１４は、図示のような平板状でも図４、図５のような凹曲面状１１やスプーン状球面１２でもよく、断面形状は特に限定されない。 According to claim 4, as described in paragraph "0027", the blade 14 that receives the wind may be a flat plate shape as shown in the figure, or a concave curved surface shape 11 or a spoon-shaped spherical surface 12 as shown in FIGS. The cross-sectional shape is not particularly limited.

請求項５によると、前記の登り坂状のガイド及び風車の下側に隙間を設けて通風路とし、前記の登り坂状のガイドや風車の上側を通過しない風が直進可能としたので、風車の外側を通る風を少なくできる。 According to the fifth aspect of the present invention, a gap is provided on the lower side of the uphill guide and the windmill to form a ventilation path so that the wind that does not pass above the uphill guide or the windmill can travel straight. Can reduce the wind passing outside.

請求項６によると、前記風車の風上側に設けた登り坂状のガイドの後端を前記水平中心軸の中心より低い位置に設けて、上向きにガイドされた風が風車の羽根の外端寄りに当たるようにしたので、風車にとって向かい風となる風を追い風に変換すると共に各羽根に最初に当たる風も風車の回転力として有効に利用できる。 According to the sixth aspect, the rear end of the uphill guide provided on the windward side of the windmill is provided at a position lower than the center of the horizontal central axis so that the wind guided upward is closer to the outer end of the blade of the windmill. Therefore, the wind that is the opposite wind for the windmill is converted into a tailwind, and the wind that strikes each blade first can be used effectively as the rotational force of the windmill.

請求項７によると、前記風車の風上側に設けた登り坂状のガイドの上端付近で管路の先端を開口させて補助風を噴出させる構造としたので、風力が弱い場合でも前記管路の先端の開口から補助風を噴出させて風車の羽根の先端寄りに向けて噴出させ風車の回転を続行できる。このとき、風車の羽根を少なくとも４枚以上とするので、羽根と羽根の間で無駄に補助風が噴出されるのを防止できる。 According to claim 7, since the tip of the pipe is opened near the upper end of the uphill guide provided on the windward side of the windmill, the auxiliary wind is ejected. It is possible to continue the rotation of the windmill by ejecting auxiliary wind from the opening at the tip and ejecting it toward the tip of the blade of the windmill. At this time, since there are at least four blades of the windmill, it is possible to prevent the auxiliary wind from being unnecessarily ejected between the blades.

請求項８のように、前記風車は、前記羽根の内端と前記中心軸の外周との間は離れて開いた構成とすると共に受けた風が前記羽根の内端と外端に逃げ出すような深溝状にしたので、前記羽根の内端と前記中心軸の外周との間が離れて開いた形態となり、前記羽根の内端側に逃げた風が一つ先の羽根の内端に当たって風車を回転させる力となる。

As in claim 8, the wind turbine is configured to be opened apart from the inner end of the blade and the outer periphery of the central shaft, and the received wind escapes to the inner end and the outer end of the blade. Since it was made into a deep groove shape, the inner end of the blade and the outer periphery of the central shaft were opened apart, and the wind that escaped to the inner end side of the blade hit the inner end of the previous blade to wind the windmill Power to rotate.

次に本発明による規模の選択が容易な風力発電装置が実際上どのように具体化されるか実施形態で説明する。図１は、本発明による風力発電装置の平面図であり、左右６個ずつ、計１２個の風車１…を水平軸２、２′に取付けてある。水平軸２、２′は、両端と中央を脚８でフレームＦに支持してある。Ｇ、Ｇ′は発電機であり、水平軸２、２′の回転力で駆動される。３、３′は風向追尾翼であり、前記水平軸２、２′の取付けフレームＦに鉛直に取付けてある。
図２は図１のＡ−Ａ′方向の側面図で、風車１…は放射状の羽根４…を例えば９０度間隔に水平軸２、２′に取付けた構造になっている。そして、前記水平軸２、２′より下側のみに、また風Ｗが到来する風上のみに登り坂状のガイド５を配設してある。すなわち、風Ｗは風車１…の上半分のみに導かれるように、上り坂状に板金などの板材で形成され、前記フレームＦに取付けてある。 Next, how the wind power generator with easy selection of the scale according to the present invention is actualized will be described in an embodiment. FIG. 1 is a plan view of a wind turbine generator according to the present invention, in which a total of 12 wind turbines 1... The horizontal shafts 2, 2 ′ are supported on the frame F by legs 8 at both ends and the center. G and G ′ are generators, which are driven by the rotational force of the horizontal shafts 2 and 2 ′. Reference numerals 3 and 3 'denote wind direction tracking blades which are vertically attached to the mounting frame F of the horizontal shafts 2 and 2'.
2 is a side view in the AA 'direction of FIG. 1, and the wind turbine 1 has a structure in which radial blades 4 are attached to the horizontal shafts 2, 2' at intervals of 90 degrees, for example. An uphill guide 5 is provided only below the horizontal shafts 2 and 2 'and only on the windward side where the wind W arrives. That is, the wind W is formed of a plate material such as a sheet metal and attached to the frame F so as to be guided only to the upper half of the wind turbine 1.

風車１…の上側にも天井ガイドを設けてあり、前記登り坂状のガイド５に対応して、下り坂状６になっている。従って、到来した風が弱くても、風車１…の上半分に集中し、増強される。すなわち、この実施例では、向かい風が追い風として作用するように、フレームＦに複数本立てた支柱７…に前記のガイド５、６などを取付けてある。
風向追尾翼３、３′は、風車１…の後ろ側に配設してあるが、風Ｗの到来する前側に或いは横側に配設してもよく、風車１…と一体的に水平回動できれば足りる。この水平回動を可能にするために、図示例では、空洞の有る円盤状のフロートでフレームＦを形成してある。円形のプールには水９を溜めてあり、その上に前記のフロート式のフレームＦを浮かべてある。このフロート式のフレームＦの中心に円筒１０を設け、この円筒１０はプール側に設けたシールで防水された状態で回動する。 A ceiling guide is also provided on the upper side of the windmills 1... Corresponding to the uphill guide 5 and has a downhill shape 6. Therefore, even if the incoming wind is weak, it concentrates on the upper half of the wind turbine 1 and is strengthened. That is, in this embodiment, the guides 5, 6, etc. are attached to a plurality of columns 7, which are erected on the frame F so that the head wind acts as a tailwind.
The wind direction tracking blades 3 and 3 'are arranged on the rear side of the wind turbines 1 ... but may be arranged on the front side or the side of the arrival of the wind W. If it can move, it is enough. In order to enable this horizontal rotation, in the illustrated example, the frame F is formed of a disk-shaped float having a cavity. Water 9 is stored in the circular pool, and the float type frame F is floated thereon. A cylinder 10 is provided at the center of the float frame F, and the cylinder 10 is rotated in a waterproof state by a seal provided on the pool side.

フレームＦは、図示のフロート式のように水の表面張力を受ける構造に代えて、水９は使用しないで、機枠の下に設けた車輪が、真円のガイドレールの上で回動することで、風向の変化に追従して機枠が回動する構造も可能である。フロートは使用しないので、支柱７…や脚８、発電機Ｇ、Ｇ′、風向追尾翼３、３′などを搭載する部位だけに一体の機枠を
設けてもよい。
前記の凹弧状のスロープになったガイド５の下側に、高さが0.５〜1.０ｍ程度の間隙ｇを設けてあることにより、風Ｗの一部は、この隙間ｇを通過する。風車１に負荷が無いと仮定した場合は、この隙間ｇを通過する風速より登り坂状のガイド５の上側を通過する風速が速いので、風車の外側に流れて風車の回転に寄与しない風を少なくできる。
なお、登り坂状のガイド５は、風車１を挟んで、後ろ側は下り坂になっており、天井側ガイド６の後ろは、風車１の天井側は水平で、その後ろ側は多少下り坂になっている。 In the frame F, instead of a structure that receives the surface tension of water as in the illustrated float type, the water 9 is not used, and the wheel provided under the machine frame rotates on a perfect guide rail. Thus, a structure in which the machine frame rotates following the change in the wind direction is also possible. Since no float is used, an integral machine frame may be provided only on the part where the support columns 7..., The legs 8, the generators G and G ′, the wind direction tracking blades 3 and 3 ′ are mounted.
A gap g having a height of about 0.5 to 1.0 m is provided on the lower side of the guide 5 having the concave arc-shaped slope, so that a part of the wind W passes through the gap g. . If it is assumed that there is no load on the windmill 1, the wind speed passing through the upper side of the uphill guide 5 is faster than the wind speed passing through the gap g, so that the wind that flows outside the windmill and does not contribute to the rotation of the windmill is generated. Less.
The uphill-shaped guide 5 is downhill on the back side with the windmill 1 in between, and the ceiling side of the windmill 1 is behind the ceiling-side guide 6 and the backside is somewhat downhill. It has become.

図３は、図１、図２の風力発電装置を正面から見た図で、発電機Ｇ、Ｇ′はベルトＢ、Ｂ′を介して前記水平軸２、２′と接続されている。
図４、図５は風車の詳細を示す図で、図４は各羽根１…を側面から見た図である。このように、図１のような放射状の帯板１…を到来する風に向けて凹面に曲げた凹面状１１にしただけでは、風圧が直ちに横から逃げる。これに対し図５は、各羽根１…の真ん中で断面にした図である。すなわち、風を受ける面がスプーンのように凹球面１２になっているため、受けた風が逃げにくく、効率良く回転する。なお、図４のような凹曲面１１付きの羽根４の両縁に鎖線のような壁板１３を設けると、風が両側に逃げるのを防ぐことができる。 FIG. 3 is a view of the wind power generator of FIGS. 1 and 2 as seen from the front. Generators G and G ′ are connected to the horizontal shafts 2 and 2 ′ via belts B and B ′.
4 and 5 are views showing the details of the windmill, and FIG. 4 is a view of each blade 1. In this way, the wind pressure immediately escapes from the side only by making the radial strips 1 as shown in FIG. On the other hand, FIG. 5 is a cross-sectional view in the middle of each blade 1. That is, since the wind receiving surface is a concave spherical surface 12 like a spoon, the received wind is difficult to escape and rotates efficiently. In addition, when the wall board 13 like a chain line is provided in both edges of the blade | wing 4 with the concave curved surface 11 like FIG. 4, it can prevent that a wind escapes to both sides.

図４、図５のように、到来する風に向けて羽根の外端寄りが湾曲した形状にした場合、登り坂状のガイド５で上向きとなった風圧が直ちに羽根４…の外端の湾曲凹面に捕捉されて、風車の回転力に切り替わり、次いで水平方向から到来する風圧で風車が効果的に回転する。或いは、水平方向に到来する風が、ガイド５による上向きの風圧で多少上向きとなって、外端寄りの湾曲凹面に捕捉される。
図４、図５の凹曲面で最も深い部位は、羽根４…の全長の１／２より外端寄りに設けた方が効果的である。
また、図４で鎖線で示すように、登り坂状のガイド５の上端を水平軸２、２′よりｈだけ低く設定するのも効果的である。その理由は、登り坂状のガイド５の上端から吹き出す風が、早めに羽根４…の外端付近に当たり、風車の回転に寄与するからである。
なお、ガイド５、６を上下反転させた構造も可能である。この場合、風車の各羽根４…の外端の湾曲凹面に風圧が捕捉されるように配置することは言うまでもない。 As shown in FIGS. 4 and 5, when the outer end of the blade is curved toward the incoming wind, the wind pressure that is directed upward by the uphill guide 5 immediately curves the outer end of the blade 4. The wind turbine is effectively rotated by the wind pressure that is captured by the concave surface and switched to the rotational force of the wind turbine and then comes from the horizontal direction. Alternatively, the wind arriving in the horizontal direction is slightly raised by the upward wind pressure by the guide 5 and is captured by the curved concave surface near the outer end.
It is more effective to provide the deepest part of the concave curved surface of FIGS. 4 and 5 closer to the outer end than 1/2 of the entire length of the blades 4.
Further, as shown by a chain line in FIG. 4, it is also effective to set the upper end of the uphill guide 5 lower than the horizontal axes 2 and 2 'by h. The reason is that the wind blown from the upper end of the uphill guide 5 hits the vicinity of the outer end of the blades 4 early and contributes to the rotation of the windmill.
A structure in which the guides 5 and 6 are turned upside down is also possible. In this case, it goes without saying that the wind pressure is arranged to be captured by the curved concave surface at the outer end of each blade 4 of the windmill.

図６は、別の実施形態の風車の斜視図で、羽根１４…の壁板１６、１７を深い三角状に形成してあり、風を受ける羽根１４は、回転軸２、２′の中心より風下寄りに移動した位置で鉛直に立っている。なお、鉛直に立った羽根１４は、図示のような平板状でも図４、図５のような凹曲面状１１やスプーン状球面１２でもよく、断面形状は特に限定されない。
図７は、羽根１４を垂直に２分割する位置の断面図であり、羽根１４が鉛直に立った状態で風が水平に矢印のように当たるとすると、最も効率良く風車が回転し、発電機を駆動できる。なお、図示例では、羽根１４の内端と回転軸の外周との間１５は開いており、離れている。 FIG. 6 is a perspective view of a windmill according to another embodiment, in which the wall plates 16 and 17 of the blades 14 are formed in a deep triangular shape, and the blades 14 that receive the wind are from the center of the rotating shafts 2 and 2 ′. Standing vertically at a position moved leeward. The blades 14 standing vertically may have a flat plate shape as shown in the figure or a concave curved surface shape 11 or a spoon-shaped spherical surface 12 as shown in FIGS. 4 and 5, and the cross-sectional shape is not particularly limited.
FIG. 7 is a cross-sectional view of the position at which the blade 14 is vertically divided into two. If the wind hits horizontally as indicated by the arrow with the blade 14 standing vertically, the wind turbine rotates most efficiently, Can drive. In the illustrated example, the space 15 between the inner end of the blade 14 and the outer periphery of the rotating shaft is open and separated.

三角状の深い壁板１６、１７が有るので、羽根１４を駆動した後は外周側と内周側に逃げるが、内周側に逃げた風は一つ先の羽根１４の下端に矢印のように当たって回転させるので、風車の回転がより円滑に行われる。
従って、羽根１４は、通常のように回転軸２、２′に直接に取付けるのでなく、片方の壁板16のみを回転軸２、２′まで延ばして取付けてあり、羽根１４や他方の壁板17には、回転軸２、２′との間に隙間１５ができ、風が通過できる。 Since there are triangular deep wall plates 16 and 17, after driving the blade 14, it escapes to the outer peripheral side and the inner peripheral side, but the wind escaping to the inner peripheral side is as indicated by an arrow at the lower end of the blade 14 ahead. Therefore, the windmill rotates more smoothly.
Accordingly, the blades 14 are not directly attached to the rotary shafts 2 and 2 'as usual, but only one wall plate 16 is extended to the rotary shafts 2 and 2', and the blades 14 and the other wall plate are attached. In 17, a gap 15 is formed between the rotary shafts 2, 2 ′, and wind can pass therethrough.

なお、常に風が吹いておればよいが、風が弱くて風力が足りないことも起こりうる。このような場合に備えて、図８のような風力補助機構を予め設けておくのがよい。そのために、登り坂状のガイド５の上端付近で、管路18の先端を開口させて風を噴出させる構造にし
てある。管路18の根本側は送風機19に接続してある。一方、例えば風上側の支柱７の頂上には風速計20を設けて、風速が規定以下に低下したことを検出したら、この検出器の信号で送風機19を始動させて、管路18の先端から補助風を噴出させ、風車１を強制的に回転させる。風速が所定の値まで回復したことが、風速計20で検出したら、送風機19を停止させる。 It should be noted that the wind is always blowing, but it is possible that the wind is weak and not enough. In preparation for such a case, a wind power assist mechanism as shown in FIG. 8 is preferably provided in advance. For this purpose, the tip of the pipe 18 is opened near the upper end of the uphill guide 5 so that wind is ejected. The root side of the pipe 18 is connected to the blower 19. On the other hand, for example, if an anemometer 20 is provided on the top of the upright support column 7 and it is detected that the wind speed has fallen below a specified value, the blower 19 is started by the signal of this detector, The auxiliary wind is ejected to forcibly rotate the windmill 1. When the anemometer 20 detects that the wind speed has recovered to a predetermined value, the blower 19 is stopped.

なお、羽根４の数が少ないと、羽根４の無い部位で補助風を噴出させるという無駄が起きるので、羽根４の数は少なくとも４枚以上は設ける必要がある。
各羽根４…の先端寄りの凹曲面に補助風が噴出されて当たるように、管路18の先端が向いておれば問題ないが、図のように登り坂状のガイド５に各風車１…毎に凹溝を設けて、その中に管路18を埋め込む構造も可能である。
このように、管路18の先端から噴出する補助風に頼る場合は、各羽根４…の外端寄りに噴出風が当たり、回転力が大きくなるように、各羽根４…の外端寄りに凹曲面を設け、しかも当たった噴出風が逃げにくい側壁13を設けたり、凹曲面11や凹球面12の曲率等が重要となる。 If the number of blades 4 is small, there is a waste that auxiliary air is blown out at a portion where there are no blades 4, so it is necessary to provide at least four blades 4.
There is no problem as long as the tip of the pipe 18 is directed so that the auxiliary wind is blown against the concave curved surface near the tip of each blade 4... A structure in which a concave groove is provided every time and the pipe line 18 is embedded therein is also possible.
As described above, when relying on the auxiliary wind ejected from the tip of the pipe line 18, the ejected wind hits the outer end of each blade 4... A concave curved surface is provided, and a side wall 13 in which the blown air that hits the surface is difficult to escape, and the curvature of the concave curved surface 11 and the concave spherical surface 12 are important.

以上のように、風車を１以上有しているので、実状に応じて容易に風車の出力を設定し、風力発電装置の規模を選択できる。しかも、風車に対する向かい風が風車に対する追い風となるようなガイドを風車の前方に設けてあるので、向かい風も有効に追い風として作用させることができ、風力を発電に効果的に変換できる。 As described above, since one or more windmills are provided, the output of the windmill can be easily set according to the actual situation, and the scale of the wind turbine generator can be selected. In addition, since a guide is provided in front of the wind turbine so that the head wind against the wind turbine becomes a tail wind with respect to the wind turbine, the head wind can also effectively act as a tail wind, and wind power can be effectively converted into power generation.
