Description

この発明は、風力発電装置付き建築物、特に勾配屋根の屋根面に吹き付ける風を効率よく風力発電装置の風車に向かわせることにより低風速時でも発電量を高めることができる技術に関するもので、個人の住宅、マンションをはじめ、公共的な建物などの建築物に利用される。   TECHNICAL FIELD The present invention relates to a building with a wind power generator, and more particularly to a technique that can increase the amount of power generation even at low wind speeds by efficiently directing the wind blown onto the roof surface of a sloped roof to the wind turbine of the wind power generator. It is used for buildings such as public housing and condominiums.

風力発電において、発電量を高めるために集風する技術として、発電装置自体に集風設備を設けたもの（例えば、特許文献１参照。）、あるいは勾配屋根の傾斜を利用して立面的に集風するもの（例えば、特許文献２参照。）、等が既に提案されている。   In wind power generation, as a technique for collecting wind in order to increase the amount of power generation, the power generation device itself is provided with wind collection equipment (see, for example, Patent Document 1), or by using the slope of a sloped roof, Those that collect air (see, for example, Patent Document 2) have already been proposed.

特開２００３−４９７６０号公報（第２頁、図１）Japanese Patent Laying-Open No. 2003-49760 (second page, FIG. 1) 特開２００３−１２９９４１号公報（第２頁、図１）JP 2003-129941 A (2nd page, FIG. 1)

しかしながら、特許文献１のように風力発電装置自体に集風設備を設けた場合には、集風できる風力が小さくて発電に限度があり、また発電装置が大掛かりなものとなってしまい、構造上、施工上不利である。また、特許文献２のように勾配屋根の傾斜を利用するものにおいては、基本的には立面的な集風しか期待できず、図７に示すように平面的な集風として期待できるのは発電装置の風車幅のみであって、それ以外の風は発電に寄与しない、という問題点があった。   However, when the wind power generation apparatus itself is provided with a wind collecting facility as in Patent Document 1, the wind power that can be collected is small, and there is a limit to power generation, and the power generation apparatus becomes large and structurally It is disadvantageous in construction. Moreover, in the thing using the inclination of a gradient roof like patent document 2, it can expect only an elevational wind collection fundamentally, but as shown in FIG. There was a problem that only the wind turbine width of the power generation device was used, and other winds did not contribute to power generation.

そこでこの発明は、前記従来の装置の問題点を解決し、発電装置自体に集風設備を設ける必要がなく、しかも立面的な集風だけではなく平面的な集風も期待できて、低風速時でも発電量の高い効率のよい風力発電を行うことができる風力発電装置付き建築物を提供することを目的とする。   Therefore, the present invention solves the problems of the conventional device, eliminates the need to provide a wind collecting facility in the power generation device itself, and can expect not only a vertical wind collection but also a flat wind collection, It aims at providing the building with a wind power generator which can perform efficient wind power generation with high electric power generation amount at the time of wind speed.

前記課題を解決するために、請求項１に記載の発明は、風車を有する風力発電装置を装備し、屋根面が傾斜又は湾曲に形成された勾配屋根をもった風力発電装置付き建築物において、前記勾配屋根の屋根面に吹き付ける風を、該発電装置の風車に向けて集風するように誘導する手段を屋根面に設けたことを特徴とする。   In order to solve the above-mentioned problem, the invention according to claim 1 is equipped with a wind turbine generator having a windmill, and in a building with a wind turbine generator having a sloped roof whose roof surface is inclined or curved, The roof surface is provided with means for guiding the wind blown onto the roof surface of the sloped roof so as to collect the air toward the wind turbine of the power generation device.

請求項２に記載の発明は、請求項１において、誘導する手段が、屋根面に直線状又は曲線状に形成された誘導凹条又は誘導凸条であることを特徴とする。   The invention described in claim 2 is characterized in that, in claim 1, the guiding means is a guide groove or a guide protrusion formed in a linear or curved shape on the roof surface.

請求項３に記載の発明は、請求項２において、誘導凹条又は誘導凸条が、屋根面と一体に形成されていることを特徴とする。請求項４に記載の発明は、請求項２において、誘導凹条又は誘導凸条が、屋根面と別体に形成され、屋根面上に止め具で取り付けられていることを特徴とする。   The invention described in claim 3 is characterized in that, in claim 2, the guide groove or the guide protrusion is formed integrally with the roof surface. The invention described in claim 4 is characterized in that, in claim 2, the guide groove or the guide protrusion is formed separately from the roof surface and attached to the roof surface with a stopper.

請求項５に記載の発明は、請求項１ないし４のいずれかにおいて、風力発電装置が、勾配屋根の頂部に複数個設置され、各風力発電装置の風車に向けて集風を誘導する手段が屋根面にそれぞれ設けられていることを特徴とする。   According to a fifth aspect of the present invention, in any one of the first to fourth aspects, a plurality of wind power generators are installed at the top of the sloped roof, and means for guiding the wind collection toward the wind turbines of each wind power generator is provided. It is provided on the roof surface, respectively.

この発明は、前記のような構成からなるので、従来のように発電装置自体に集風設備を設ける必要がなく、しかも誘導する手段により立面的な集風だけではなく平面的な集風も期待できて、低風速時でも発電量の高い効率のよい風力発電を行うことができる。   Since the present invention is configured as described above, it is not necessary to provide a wind collecting facility in the power generation apparatus itself as in the prior art, and not only a vertical wind collection but also a planar wind collection by the guiding means. It can be expected that high-efficiency wind power generation with high power generation can be performed even at low wind speeds.

この発明の実施の形態を、添付図面を参照して説明する。   Embodiments of the present invention will be described with reference to the accompanying drawings.

図１は切妻屋根の一般的な建築物を示す概略正面図、図２はその概略平面図である。１は建築物を示し、該建築物の勾配屋根２の中央頂部には風力発電装置３が１個設置されている。風力発電装置３は図３に示すように既に知られており、垂直軸風車の一例としてのサボニウス形風車５を有している。このサボニウス形風車５はあくまでも一例であって、その他の種類の垂直軸風車を排除するものではなく、また風車であれば必ずしも垂直軸風車でなくともよく、水平軸風車でもよい。尚、発電装置３の設置の詳細は省略しているが、例えば発電装置３が風車５を勾配屋根２の屋根面の最高位とほぼ同一高さとなるようにして頂部に形成した凹所に設置される。   FIG. 1 is a schematic front view showing a general building with a gable roof, and FIG. 2 is a schematic plan view thereof. Reference numeral 1 denotes a building, and one wind power generator 3 is installed at the central top of the sloped roof 2 of the building. The wind turbine generator 3 is already known as shown in FIG. 3, and has a Savonius type windmill 5 as an example of a vertical axis windmill. The Savonius-type windmill 5 is merely an example, and does not exclude other types of vertical axis windmills. If the windmill is not necessarily a vertical axis windmill, it may be a horizontal axis windmill. Although details of the installation of the power generation device 3 are omitted, for example, the power generation device 3 is installed in a recess formed at the top so that the wind turbine 5 is almost the same height as the highest level of the roof surface of the sloped roof 2. Is done.

勾配屋根２の一方の屋根面には、図４（Ａ）に示すように勾配屋根に吹き付ける風を、発電装置３の風車５に向けて集風するように誘導する手段６としての直線状の誘導凸条６ａがガイドレールの如く屋根面７と一体に形成されている。誘導凸条６ａは縦断面が方形で、かつ高さが５０〜２００mm程度で形成され、図２のように屋根２の軒先近くから発電装置３の風車近くまで、隣接する誘導凸条６間が軒先近くで広く、風車近くで狭くなるように延び、隣接する誘導凸条６間を矢印で示すように風の通路としている。図４（Ｂ），（Ｃ），（Ｄ）は誘導凸条６ａに代わる他の誘導手段６の例を示す。すなわち、図４（Ｂ）は誘導凹条６ｂが屋根面７に一体に形成されている例を示し、縦断面が方形で、かつ深さが５０〜２００mm程度で形成されている。図４（Ｃ）は誘導凹条６ｃの縦断面が逆三角形となっている点を除けば、誘導凹条６ｂと同様である。図４（Ｄ）は図４（Ａ），（Ｂ），（Ｃ）が屋根面７と一体に形成されているのに対して、屋根面７と別体に止め具で取り付けられた誘導凸条６ｄの例を示し、この例では誘導凸条６ｄは縦断面が略Ｌ形を呈する鋼材からなっている。８はその止め具を示す。前記のような誘導凸条６ａ，６ｄ又は誘導凹条６ｂ，６ｃは、屋根２の大きさや集風の程度にもよるが、図２に示すように一方の屋根面７に概ね５〜６本程度形成される。   On one roof surface of the sloped roof 2, as shown in FIG. 4A, a straight line as means 6 for guiding the wind blown to the sloped roof toward the windmill 5 of the power generation device 3 is collected. The guide protrusion 6a is formed integrally with the roof surface 7 like a guide rail. The guide ridge 6a has a square longitudinal section and a height of about 50 to 200 mm, and between the adjacent guide ridges 6 from the vicinity of the eaves of the roof 2 to the wind turbine of the power generator 3 as shown in FIG. It extends so as to be narrow near the eaves and narrow near the windmill, and a wind passage is formed between the adjacent guide ridges 6 as indicated by arrows. FIGS. 4B, 4C, and 4D show examples of other guiding means 6 that replace the guiding ridge 6a. That is, FIG. 4 (B) shows an example in which the guide groove 6b is formed integrally with the roof surface 7, and the vertical cross section is square and the depth is about 50 to 200 mm. FIG. 4C is the same as the guide groove 6b except that the longitudinal section of the guide groove 6c is an inverted triangle. FIG. 4 (D) shows that the guiding projections attached to the roof surface 7 separately from the roof surface 7 by means of fasteners, whereas FIGS. 4 (A), (B) and (C) are formed integrally with the roof surface 7. An example of the strip 6d is shown. In this example, the guide projection 6d is made of a steel material having a substantially L-shaped longitudinal section. 8 shows the stopper. The guide ridges 6a and 6d or the guide ridges 6b and 6c as described above are approximately 5 to 6 on one roof surface 7 as shown in FIG. 2, although it depends on the size of the roof 2 and the degree of wind collection. Formed to a degree.

図５は誘導手段６の変形例を示し、この例では一部の誘導手段６が直線状でなく、曲線状に形成されて、風を発電装置３の風車５に誘導するようになっている。すなわち、風車５に向かって一側が直線状の誘導手段に、他側が曲線状の誘導手段に形成されている。このような直線状又は曲線状の誘導手段６は勾配屋根２の状態や吹き付ける風の向き等を考慮して配置する。   FIG. 5 shows a modification of the guiding means 6. In this example, a part of the guiding means 6 is formed not in a straight line but in a curved shape so as to guide the wind to the wind turbine 5 of the power generation device 3. . That is, the one side is formed as a straight guiding means and the other side is formed as a curved guiding means toward the wind turbine 5. Such a linear or curved guiding means 6 is arranged in consideration of the state of the sloped roof 2 and the direction of the blowing wind.

前記のような構成からなるので、立面的な集風について従来通り期待できることは勿論、平面的な集風についても誘導手段６によって勾配屋根２の屋根面７に吹き付ける風を発電装置３の風車５に誘導することができる。そのため従来のように発電装置３の風車５幅以外の風が無駄になって風力発電に寄与しないということがなく、このような風も有効に利用できて、発電装置３で発電量の高い効率のよい風力発電を行うことが可能となる。したがって、低風速時でも発電装置３の発電が可能である。また、発電装置３が勾配屋根２の頂部に設置されているので、風力発電の無指向的な効果が得られる。   Since it is configured as described above, it is possible to expect a vertical wind collection as usual, and also a wind blown to the roof surface 7 of the gradient roof 2 by the guiding means 6 for the planar wind collection of the power generator 3. 5 can be induced. Therefore, winds other than the width of the wind turbine 5 of the power generation device 3 are not wasted and do not contribute to wind power generation as in the prior art, and such wind can be used effectively, and the power generation device 3 has a high power generation efficiency. It is possible to perform wind power generation with good quality. Therefore, the power generation device 3 can generate power even at low wind speeds. Further, since the power generation device 3 is installed on the top of the sloped roof 2, an omnidirectional effect of wind power generation can be obtained.

図６は勾配屋根２の頂部に風力発電装置３を複数個（２個）設置した例を示すもので、この例では屋根２の両端部分に風力発電装置３を設置している。そして勾配屋根２の屋根面７に吹き付ける風を各風力発電装置３の風車５に向けて集風するように誘導する手段６が設けられている。このような例は比較的大きな建築物において、大発電量を需要とする場合に好適である。   FIG. 6 shows an example in which a plurality (two) of wind power generators 3 are installed on the top of the sloped roof 2. In this example, the wind power generators 3 are installed at both ends of the roof 2. And the means 6 which guide | induces so that the wind sprayed on the roof surface 7 of the gradient roof 2 may be collected toward the windmill 5 of each wind power generator 3 is provided. Such an example is suitable when a large amount of power is demanded in a relatively large building.

前記実施の形態では勾配屋根２の一方の屋根面に誘導する手段６を設けたが、他方の屋根面にも設け屋根全面にわたって設けてもよく、あるいは片流れの勾配屋根の屋根面に設けてもよい。また風力発電装置３を勾配屋根２の頂部に設置したが、必ずしも頂部でなくともよく、風力のある適所でよい。さらに誘導手段６として示した誘導凸条６ａ，６ｄ又は誘導凹条６ｂ，６ｃも好ましい一例を挙げたにすぎず、これ以外のものを排除するものではなく、さらにまた屋根２の形状も寄棟屋根、方形屋根など勾配のある屋根であれば任意のものに適用ができる等、その実施に際しては請求項に記載した範囲内で適宜その設計を変更、修正することができる。   In the above embodiment, the means 6 for guiding to one roof surface of the sloped roof 2 is provided, but it may also be provided on the other roof surface over the entire roof surface, or may be provided on the roof surface of a single-flow gradient roof. Good. Moreover, although the wind power generator 3 was installed in the top part of the gradient roof 2, it may not necessarily be a top part and may be a suitable place with a wind force. Further, the guide ridges 6a and 6d or the guide ridges 6b and 6c shown as the guide means 6 are merely preferable examples, and other things are not excluded, and the shape of the roof 2 is also dormitory. The roof can be applied to any roof with a slope, such as a square roof. For example, the design can be changed or modified as appropriate within the scope of the claims.
