Hereinafter, the wind power generation device according to the embodiment of the present invention will be described with reference to the drawings.
図１は、本発明の実施の形態１〜６に係る風力発電装置の基本構造を示している。風力導入第一風路１００（後述する導管１１に繋ぐ）を兼ねる柱Ｒ１（芯柱）の基端は、土台２に立設されており、図示しない筋交部材で補強されている。この柱Ｒ１は風力導入第一風路１００を備えた中空形状であり、空気（風力）を取込む構成である。柱Ｒ１は、床下から、少なくとも、建屋Ｒの天井Ｒ２に到る構造である。柱Ｒ１は、耐震機能を備える。例えば、鋼管とする。この柱Ｒ１は、床下と屋根との気圧差（高低差）により発生する上昇による風（上昇気流、又は位置エネルギー）を生成する。地下空気（床下）、又は地中空気を取込む床下空間の入口１０１（開口）を備えており、前記柱Ｒ１の風力（空気）導入第一風路１００に繋がり、後述する屋根裏Ｒ４に配備した発電室３に到る。この発電室３には、入口１０１と風力導入第一風路１００を経由して、自然気流Ｘ１（蒸気、またはガス等を含む）とか、後述する、発電機、ストーブ、又はその他の機械からの人工風を生成するハイブリッドＡの発電装置を備えることも有り得る。
図中１０２は、空中の空気を取入れる風力（空気）導入第二風路を示す。風力導入第二風路１０２は、風力導入第一風路１００を邪魔しない位置で発電室３に繋がる。また、図示しないが、風力導入第一・第二風路１００・１０２には、それぞれ切換弁を備えてあり、風力導入経路を制御できる。
FIG. 1 shows the basic structure of the wind power generation device according to the first to sixth embodiments of the present invention. The base end of the pillar R1 (core pillar) that also serves as the wind power introduction first air passage 100 (connecting to the conduit 11 described later) is erected on the base 2 and is reinforced by a bracing member (not shown). This pillar R1 has a hollow shape provided with a wind power introduction first air passage 100, and has a configuration for taking in air (wind power). The pillar R1 has a structure that reaches at least the ceiling R2 of the building R from under the floor. The pillar R1 has a seismic function. For example, a steel pipe. The pillar R1 generates wind (updraft or potential energy) due to the rise generated by the pressure difference (height difference) between the underfloor and the roof. It is equipped with an entrance 101 (opening) of an underfloor space that takes in underground air (underfloor) or underground air, is connected to the wind power (air) introduction first air passage 100 of the pillar R1, and is deployed in the attic R4 described later. It reaches the power generation room 3. The power generation chamber 3 is provided with a natural air flow X1 (including steam, gas, etc.) or a generator, a stove, or other machine described later via the inlet 101 and the first wind path 100 for introducing wind power. It is also possible to have a hybrid A power generator that generates artificial wind.
In the figure, 102 shows a second wind path for introducing wind power (air) that takes in air in the air. The wind power introduction second air passage 102 is connected to the power generation chamber 3 at a position that does not interfere with the wind power introduction first air passage 100. Further, although not shown, the wind power introduction first and second air passages 100 and 102 are provided with switching valves, respectively, and can control the wind power introduction route.
そして、発電室３に繋がる風力排気風路５（風路となり、柱Ｒ１となる）が形成されており、風力排気風路５は屋根裏Ｒ４より空中高く配備され、かつ排気風力が建屋Ｒの周辺風力に邪魔されない構造である。図中５００は排気口である。この風力排気風路５は、風力導入第一風路１００に嵌合されており、回転自在である。この回転を司る風見鶏５０１を有する。風力排気風路５は、柱Ｒ１となり、前述の効果が期待できる。また、排気口５００からの風力の排気で、この排気口５００の下側と近傍に負圧領域を形成し、風力導入第一・第二風路１００・１０２と導管１１等に風力誘引効果を与えることもできる。図中６は入口１０１に設けたシャッタで、自動制御である。
Then, a wind exhaust air passage 5 (which becomes an air passage and becomes a pillar R1) connected to the power generation chamber 3 is formed, the wind exhaust air passage 5 is deployed higher in the air than the attic R4, and the exhaust wind power is around the building R. It is a structure that is not disturbed by wind power. In the figure, 500 is an exhaust port. The wind exhaust air passage 5 is fitted to the wind power introduction first air passage 100 and is rotatable. It has a weathercock 501 that controls this rotation. The wind exhaust air passage 5 becomes a pillar R1, and the above-mentioned effect can be expected. Further, the exhaust of wind power from the exhaust port 500 forms a negative pressure region on the lower side and the vicinity of the exhaust port 500, and exerts a wind power attracting effect on the wind power introduction first and second air passages 100 and 102 and the conduit 11 and the like. You can also give. In the figure, 6 is a shutter provided at the inlet 101, which is automatically controlled.

The conduit 11 is a tubular member for passing air, and is set to, for example, a diameter of 5 cm. The impeller 21 (wind turbine structure) is an element that converts wind power into rotational kinetic energy, and is set to, for example, a diameter of 15 cm and a width of 5 cm. FIG. 2 is a perspective sectional view of a cross section of the wind turbine generator 1 cut in a plane perpendicular to the central axis at the center in the thickness direction (Z direction described later) of the impeller 21 when viewed from the cut side. It is shown. As shown in FIG. 1, the wind power introduction first air passage 100 is configured to also serve as the pillar R1 of the building. In addition, with this structure, seismic effects can be expected.
図３〜図３−２は、実施の形態１に係る風力発電装置１の正面視した断面図であり、収れん部１４、殊に、狭窄部１４ａの、好ましい、各構成を説明する。
図７に示すように、実施の形態１に係る風力発電装置１の羽根車２１は、例えば、１対の環状輪郭体２４（羽根車２１の外郭体）の間に、複数の羽根２５を差し渡して構成される。羽根２５の各々は、例えば、１枚の平板２２と、１枚の傾斜板２３とで形成される。なお、羽根２５は、対の環状輪郭体２４（羽根車２１の外郭体）の間に、均等に（整然と）配備されている。また、この導管１１には、その両端にそれぞれ吸気端１２及び排気端１３を形成するとともに、後述する羽根車２１に接触する部位に導管本体収れん部１４を形成する。この例では、導管本体収れん部１４は、導管１１の一方の内壁曲面より突出した膨出曲面形状の突部１４ａ１と、対峙する羽根車２１の輪郭体２４、又は導管１１の他方の内壁曲面とで形成した、断面視して、切欠きした半月形状、又は眞半月形状等の狭窄部１４ａであり、収れん部１４（狭窄部１４ａ）は、当該導管１１を流れる風の流れ、向き又は強さを調節する（絞り形態である）。この例では、狭窄部１４ａは、導管１１の管路内に形成した羽根車２１の陥入を許す滑らかに凹んだ部分（各形態を後述する）をいう。狭窄部１４ａは、後述する図２〜図４−４と、図８〜図１０に示した、それぞれの形態があるが、何れも一例である。
なお、図２や図７などでは、この対の輪郭体２４の中間に位置する支持構造も、環状輪郭体２４として示してあるが、図２−１に示すように、羽根２５の軸側（裏側）の面を面一に覆う、いわば対の輪郭体２４と中間の輪郭体２４とを一体化した構造の環状輪郭体２４も有り得る。
3 to 3-2 are front-view sectional views of the wind power generation device 1 according to the first embodiment, and each preferred configuration of the astringent portion 14, particularly the constricted portion 14a, will be described.
As shown in FIG. 7, in the impeller 21 of the wind power generation device 1 according to the first embodiment, for example, a plurality of blades 25 are passed between a pair of annular contour bodies 24 (outer bodies of the impeller 21). It is composed of. Each of the blades 25 is formed of, for example, one flat plate 22 and one inclined plate 23. The blades 25 are evenly (orderly) arranged between the pair of annular contours 24 (outer bodies of the impeller 21). Further, the conduit 11 is formed with an intake end 12 and an exhaust end 13 at both ends thereof, and a conduit body converging portion 14 is formed at a portion in contact with the impeller 21 described later. In this example, the conduit body converging portion 14 includes a protruding curved surface-shaped protrusion 14a1 protruding from one inner wall curved surface of the conduit 11 and a contour body 24 of the impeller 21 facing the conduit 11 or the other inner wall curved surface of the conduit 11. It is a constricted portion 14a formed in the above, and has a notched half-moon shape or a true half-moon shape in cross section, and the converging portion 14 (narrowed portion 14a) is the flow, direction or strength of the wind flowing through the conduit 11. (Astringent form). In this example, the narrowed portion 14a refers to a smoothly recessed portion (each form will be described later) that allows the impeller 21 formed in the conduit of the conduit 11 to enter. The narrowed portion 14a has the respective forms shown in FIGS. 2 to 4-4 and 8 to 10 which will be described later, and all of them are examples.
In addition, in FIG. 2 and FIG. 7, the support structure located in the middle of the pair of contour bodies 24 is also shown as the annular contour body 24, but as shown in FIG. 2-1 the axial side of the blade 25 ( There may be an annular contour body 24 having a structure in which a pair of contour bodies 24 and an intermediate contour body 24 are integrated so as to cover the surface of the back side) flush with each other.
また、導管１１には、膨出した扁平かつ略球状の部屋１６（狭窄部１４ａと同じ）を備えており、この部屋１６には、羽根車２１の一部（風取込み部屋２５ａ）を回転自在に、軸支されている（収容されている）。また、実施例では、該部屋１６は、例えば、導管１１の壁を外側に膨出させる形で形成されており、導管１１の内部空間と気密に連通した空間部位であって、前述の如く、羽根車２１が、滑らかな回転を確保するためにも部屋１６の内面と僅かなクリアランスをもって、収められている。
Further, the conduit 11 is provided with a bulging flat and substantially spherical chamber 16 (same as the narrowed portion 14a), and a part of the impeller 21 (wind intake chamber 25a) can be rotated in this chamber 16. It is pivotally supported (contained). Further, in the embodiment, the room 16 is formed, for example, in a form in which the wall of the conduit 11 is bulged outward, and is a space portion airtightly communicated with the internal space of the conduit 11, as described above. The impeller 21 is housed with a slight clearance from the inner surface of the room 16 in order to ensure smooth rotation.
図２〜図３−２に示すように、部屋１６に収容された羽根車２１の一部２１ａ（図３において、羽根車２１の導管１１側であって、少なくとも、風取込み部屋２５ａ（ポケット））は、導管１１の右側に陥入（嵌入）されている。導管１１の吸気端１２側と羽根車２１の傾斜板２３とか、平板２２、又は部屋１６の表面は、いずれも滑らかな曲面、又は平面等の壁面で形成されており、両者は、滑らかに接続する。また、導管１１の吸気端１２側と羽根車２１の平板２２も接続する。これにより、導管１１の吸気端１２から流入した風は、狭窄部１４ａで平板２２に衝突し、回転軸２９を中心として羽根車２１を回転させる。図２、図３においては、羽根車２１の回転方向は、例えば、時計回りである。図２、図３に示すように、流入した風が平板２２に衝突する直前の向きと平板２２は垂直であるため、風力が高い効率で羽根車２１の回転に係る運動エネルギーに変換される。また、部屋１６により、導管１１を通る風力の逃げが最小限となり、羽根車２１に効果的に風力を伝達することが可能となっている。羽根車２１を回転させた風は、導管１１の排気端１３から排出される（風力排気風路５に送られる）。
なお、導管１１の吸気端１２には、前述の如く、風力導入第一風路１００が、また排気端１３には、大気中に、働きを終えた風を排出する風力排気風路５が接続される。
As shown in FIGS. 2 to 3-2, a part 21a of the impeller 21 housed in the room 16 (in FIG. 3, at least the wind intake room 25a (pocket) on the conduit 11 side of the impeller 21). ) Is recessed (fitted) on the right side of the conduit 11. The surface of the intake end 12 side of the conduit 11 and the inclined plate 23 of the impeller 21, the flat plate 22, or the room 16 are all formed of a smooth curved surface or a wall surface such as a flat surface, and the two are smoothly connected. To do. Further, the intake end 12 side of the conduit 11 and the flat plate 22 of the impeller 21 are also connected. As a result, the wind flowing from the intake end 12 of the conduit 11 collides with the flat plate 22 at the narrowed portion 14a, and rotates the impeller 21 around the rotating shaft 29. In FIGS. 2 and 3, the direction of rotation of the impeller 21 is, for example, clockwise. As shown in FIGS. 2 and 3, since the direction immediately before the inflowing wind collides with the flat plate 22 and the flat plate 22 are perpendicular to each other, the wind power is converted into kinetic energy related to the rotation of the impeller 21 with high efficiency.

Explaining the impeller 21 in detail, the impeller 21 is a wind receiving chamber provided by passing a large number of the contour bodies 24 formed of a pair of strip-shaped rings and the contour bodies 24 of the pair. It is composed of a blade 25, a flat plate 22 and an inclined plate 23 forming the blade 25, a spoke 27 connected to the contour body 24 and / or the blade 25, and a rotating shaft 29 supporting the central portion of the spoke 27. The contour body 24 is formed in an annular shape centered on the rotation shaft 29, supports the flat plate 22 and the inclined plate 23, and constitutes the outer shell of the impeller 21 in the radial direction (in the form of a water wheel). The spokes 27 are flat plate-shaped members that maintain the radial strength of the impeller 21, and the circumferential support member 28 is a cylindrical member that maintains the circumferential strength of the impeller 21. The spokes 27 and the circumferential support member 28 intersect at right angles. The impeller 21 made of such a member has sufficient strength against both a force in the rotational direction and a force in the radial direction.
The rotating shaft 29 is the central shaft of the impeller 21, and the rotational force is directly or indirectly transmitted to a generator (not shown) by a rod-shaped member such as a shaft (not shown). This converts wind power into electricity. The rotation shaft 29 is located at the intersection of the plurality of spokes 27.
The impeller 21 according to the present embodiment is provided with, for example, eight spokes 27 about the rotation shaft 29, and is formed at a position rotated every 45 °.
図５は、実施の形態１に係る羽根車２１の正面図である。理解を容易にするため、図５において、平板２２及び傾斜板２３は省略されている。また、図６に示すように、実施の形態１（他の態様も同じ）の羽根車２１の幅は一定である。
FIG. 5 is a front view of the impeller 21 according to the first embodiment. In FIG. 5, the flat plate 22 and the inclined plate 23 are omitted for ease of understanding. Further, as shown in FIG. 6, the width of the impeller 21 of the first embodiment (the same applies to other aspects) is constant.
図７は、実施の形態１に係る羽根車２１の斜視図である。図示のように、実施の形態１においては、図２に示すように、羽根車２１は、平板２２と傾斜板２３（風取込み部屋２５ａ）を、例えば、それぞれ３０枚ずつ備えている。平板２２は、回転軸２９と同一の平面上にある。即ち、導管１１を上昇してきた風が、狭窄部１４ａから羽根２５に入るときに、平板２２に正面より当たり、最大の力が発生する構成である。当たる方向を、図９−１の（イ）、（ロ）において、直角ｒで示す。傾斜板２３は、隣接する２つの平板２２の間に形成されている。傾斜板２３の一端は、ある平板２２の回転軸２９から遠い側の端と接し、傾斜板２３の他端は、隣接する別の平板２２の回転軸２９側の端と接している。傾斜板２３は、回転軸２９に向って凹んだ斜面（曲面状のスロープ）として形成されている。この羽根車２１は、図１５の表の（Ａ）を参照されたい。その他の羽根車２１としては、例えば、図２−１は、傾斜板２３を有さず、平板２２と輪郭体２４とで風取込み部屋２５ａを形成する、簡易型の羽根車である。図１５の表の（Ｂ）を参照されたい。
FIG. 7 is a perspective view of the impeller 21 according to the first embodiment. As shown in the figure, in the first embodiment, as shown in FIG. 2, the impeller 21 includes, for example, 30 flat plates 22 and 30 inclined plates 23 (wind intake chamber 25a). The flat plate 22 is on the same plane as the rotating shaft 29. That is, when the wind rising from the conduit 11 enters the blade 25 from the narrowed portion 14a, it hits the flat plate 22 from the front and the maximum force is generated. The direction of contact is indicated by a right angle r in (a) and (b) of FIG. 9-1. The inclined plate 23 is formed between two adjacent flat plates 22. One end of the inclined plate 23 is in contact with the end of one flat plate 22 on the side far from the rotating shaft 29, and the other end of the inclined plate 23 is in contact with the end of another adjacent flat plate 22 on the rotating shaft 29 side. The inclined plate 23 is formed as a slope (curved slope) recessed toward the rotation axis 29. For the impeller 21, refer to (A) in the table of FIG. As another impeller 21, for example, FIG. 2-1 is a simple impeller that does not have the inclined plate 23 and forms the wind intake chamber 25a with the flat plate 22 and the contour body 24. See (B) in the table of FIG.
［実施の形態２］
図８は、実施の形態２に係る風力発電装置１の正面断面図である。図示のように、実施の形態２の導管１１は、狭窄部１４ａの羽根車２１から遠い側（−Ｙ方向）に、支持板３１を備えている。吸気端１２から流入した風は、その一部が狭窄部１４ａ付近のカーブに沿って羽根車２１に導かれ、他の一部が導管１１の方向に直進して支持板３１に衝突する。これにより、支持板３１がない場合に比べ、強い風が流入した場合でも、導管１１や羽根車２１が破損し難い。また、支持板３１に衝突した風は、その後、羽根車２１に向かい、羽根車２１を回転させることになるため、エネルギーの損失が少なく、高効率の発電を維持することができる。尚、支持板３１には、余剰風力を逃がす開口を形成する構造も有り得る。
[Embodiment 2]
FIG. 8 is a front sectional view of the wind power generation device 1 according to the second embodiment. As shown in the figure, the conduit 11 of the second embodiment includes a support plate 31 on the side (-Y direction) of the narrowed portion 14a from the impeller 21. A part of the wind flowing in from the intake end 12 is guided to the impeller 21 along the curve near the narrowed portion 14a, and the other part goes straight in the direction of the conduit 11 and collides with the support plate 31. As a result, the conduit 11 and the impeller 21 are less likely to be damaged even when a strong wind flows in, as compared with the case where the support plate 31 is not provided. Further, since the wind colliding with the support plate 31 then heads toward the impeller 21 and rotates the impeller 21, energy loss is small and high-efficiency power generation can be maintained. The support plate 31 may also have a structure for forming an opening for allowing excess wind power to escape.
