JP 2005-83327 A

上記特許文献１に開示された複合発電装置では、太陽電池モジュールを利用した太陽光発電と、上昇気流を利用した風力発電との両方を利用することにより、電気エネルギーを安定して供給できるという利点がある。そして、上記特許文献１には、太陽電池モジュールが太陽光により暖められると同時に、発電による発熱で風洞の内部温度が上昇することにより風洞内部の空気が暖められて上昇気流が発生すると記載されている。しかし、上記のように太陽電池モジュールを利用した太陽光発電を行った場合には、太陽光のエネルギーの一部が電気エネルギーに変換されるために、太陽光のエネルギーの全てを風洞の加熱に利用した場合に比べて加熱効率が低下することが避けられず、上記風洞を設けたにも拘わらず、風力発電の発電効率を効果的に向上させることができないという問題がある。   The combined power generation device disclosed in Patent Document 1 has an advantage that electric energy can be stably supplied by using both solar power generation using a solar cell module and wind power generation using an updraft. There is. Patent Document 1 describes that the solar cell module is heated by sunlight, and at the same time, the internal temperature of the wind tunnel rises due to the heat generated by the power generation, so that the air inside the wind tunnel is warmed and an updraft is generated. Yes. However, when solar power generation using a solar cell module is performed as described above, a part of the solar energy is converted into electric energy, so that all of the solar energy is used for heating the wind tunnel. There is a problem that the heating efficiency is inevitably lowered as compared with the case where it is used, and the power generation efficiency of wind power generation cannot be effectively improved despite the provision of the wind tunnel.

本発明は、上記の問題点に鑑みてなされたものであり、太陽光のエネルギーを有効に利用して風力発電の発電効率を向上させることができる風力発電装置を提供することを目的としている。   The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a wind power generator capable of improving the power generation efficiency of wind power generation by effectively using the energy of sunlight.

請求項１に係る発明は、高所に設置された発電機と、この発電機を回転駆動する風車と、地上付近の外気を上記風車の設置部に案内する風洞とを備え、この風洞に、太陽光を集光するレンズ体と、このレンズ体により集光された太陽光のエネルギーによって加熱される加熱板とを設けたものである。   The invention according to claim 1 includes a generator installed at a high place, a windmill that rotationally drives the generator, and a wind tunnel that guides outside air near the ground to the installation section of the windmill, A lens body that collects sunlight and a heating plate that is heated by the energy of sunlight collected by the lens body are provided.

請求項２に係る発明は、上記請求項１記載の風力発電装置において、風洞内に発生した上昇気流を旋回させるガイド羽根を風洞の内部に設けたものである。   According to a second aspect of the present invention, in the wind turbine generator according to the first aspect, guide vanes for turning the updraft generated in the wind tunnel are provided inside the wind tunnel.

請求項３に係る発明は、上記請求項１または２に記載の風力発電装置において、加熱板に注水する注水手段を備えたものである。   The invention according to claim 3 is the wind power generator according to claim 1 or 2, further comprising water injection means for injecting water into the heating plate.

請求項１に係る発明によれば、風洞に照射された太陽光がレンズ体により集光されて内筒が高温に加熱されるため、風洞内の空気密度が低下して上昇気流が発生するとともに、これに対応して風洞の下端部開口部から風洞内に外気が連続的に導入され、上記風洞を介して風車の設置部に案内されることになる。したがって、高所に吹き付けられた風のエネルギーと、風洞に照射された太陽光のエネルギーとの両方を有効に利用して風車を高速で回転させることにより、発電機の発電効率を効果的に向上できるという利点がある。   According to the first aspect of the present invention, since the sunlight irradiated to the wind tunnel is collected by the lens body and the inner cylinder is heated to a high temperature, the air density in the wind tunnel is reduced and an upward air flow is generated. Correspondingly, outside air is continuously introduced into the wind tunnel from the opening at the lower end of the wind tunnel, and is guided to the wind turbine installation section through the wind tunnel. Therefore, the power generation efficiency of the generator is effectively improved by rotating the windmill at high speed by effectively using both the energy of the wind blown to the high place and the energy of the sunlight irradiated to the wind tunnel. There is an advantage that you can.

請求項２に係る発明によれば、風洞内において発生した上昇気流をスパイラル流に変化させることにより、風洞内をスムーズに流動させて上記風車を効率よく回転駆動することができる。   According to the second aspect of the present invention, the updraft generated in the wind tunnel is changed into a spiral flow, so that the wind turbine can be smoothly rotated and driven efficiently.

請求項３に係る発明によれば、加熱板に注水して風洞内に蒸気を発生させることにより、風洞内における上昇気流を効果的に強化できるという利点がある。   According to the invention which concerns on Claim 3, it has the advantage that the updraft in a wind tunnel can be strengthened effectively by pouring water into a heating plate and generating a vapor | steam in a wind tunnel.

図１は、本発明に係る風力発電装置の実施形態を示している。この風力発電装置は、ビル１の屋上等に設置された発電機２と、この発電機２を回転駆動する風車３と、地上付近の外気を風車３の設置部に案内する風洞４とを備えている。この風洞４は、ビル１の南側に位置する壁面に沿ってビル１の２階部分等から屋上まで設置され、その下端部が南側に向けて開口するとともに、上端部が上記風車３に向けて開口している。   FIG. 1 shows an embodiment of a wind turbine generator according to the present invention. This wind turbine generator includes a generator 2 installed on the roof of the building 1, a windmill 3 that rotationally drives the generator 2, and a wind tunnel 4 that guides outside air near the ground to the installation section of the windmill 3. ing. This wind tunnel 4 is installed from the second floor portion of the building 1 to the rooftop along the wall surface located on the south side of the building 1, and its lower end portion opens toward the south side, and its upper end portion faces the windmill 3. It is open.

上記風洞４は、図２および図３に示すように、太陽光を集光するレンズ体５が設置された外筒６と、その内方側に設置された内筒７からなる加熱板とを有し、これらの直径が上端部に至る程小さくなるように設定されることにより上窄まりに形成されている。レンズ体５は、複数の凸レンズ状部８が一定間隔で設置されたガラス製の板材からなっている。そして、多数のレンズ体５が取付枠体９に嵌め込まれて接着またはボルト止め等の手段で固定されることにより、上記外筒６が構成されている。また、内筒７は、鋼板または銅板等によって形成された円筒状体からなり、その外面が黒色に着色されている。そして、上記凸レンズ状部８により集光された太陽光Ａが内筒７上において焦点を結ぶように、上記外筒６と内筒７との間隔Ｓが設定されている。   As shown in FIGS. 2 and 3, the wind tunnel 4 includes an outer cylinder 6 provided with a lens body 5 for collecting sunlight and a heating plate including an inner cylinder 7 installed on the inner side thereof. It is formed so as to be constricted by setting these diameters to be smaller as they reach the upper end. The lens body 5 is made of a glass plate material in which a plurality of convex lens-shaped portions 8 are installed at regular intervals. The outer cylinder 6 is configured by fitting a large number of lens bodies 5 into the attachment frame body 9 and fixing them by means such as adhesion or bolting. Moreover, the inner cylinder 7 consists of a cylindrical body formed with a steel plate, a copper plate, etc., and the outer surface is colored black. And the space | interval S of the said outer cylinder 6 and the inner cylinder 7 is set so that the sunlight A condensed by the said convex lens-shaped part 8 may focus on the inner cylinder 7. FIG.

上記風車３は、図４および図５に示すように、弓形に湾曲したブレード材からなる３枚のダリウスロータ１１と、複数枚の半円筒状体が組み合わされた上下一対のサポニウスロータ１２，１３とを有し、これらのロータ１１〜１３がビル１の屋上に吹き付けた風に応じて回転することにより発電を行うように構成されている。すなわち、上記ロータ１１〜１３がそれぞれ垂直軸１０に取り付けられるとともに、その基端部に発電機２が設置され、上記垂直軸１０がロータ１１〜１３と一体に回転駆動されることにより、上記発電機２による発電が行われるようになっている。   As shown in FIGS. 4 and 5, the wind turbine 3 includes a pair of upper and lower Saponius rotors 12 in which three Darrieus rotors 11 made of an arcuate blade material and a plurality of semicylindrical bodies are combined. 13 and these rotors 11-13 are comprised so that it may generate electric power by rotating according to the wind which sprayed on the roof of the building 1. FIG. That is, the rotors 11 to 13 are respectively attached to the vertical shaft 10, the generator 2 is installed at the base end thereof, and the vertical shaft 10 is rotationally driven integrally with the rotors 11 to 13, thereby Power generation by the machine 2 is performed.

また、上記風洞４は、その上端部が下方のサポニウスロータ１３の右半部を指向するように設置され、後述するように風洞４内において発生した上昇気流Ｂが、風洞４の上端開口部からサポニウスロータ１３の右半部に吹き付けられることにより、上記風車３が回転駆動されるように構成されている。   Further, the wind tunnel 4 is installed so that the upper end portion thereof is directed to the right half of the lower Saponius rotor 13, and as will be described later, the upward air flow B generated in the wind tunnel 4 is the upper end opening of the wind tunnel 4. The windmill 3 is rotated by being blown to the right half of the saponius rotor 13.

上記構成において、ビル１の南側壁面に沿って設置された風洞４に太陽光Ａが照射されると、上記レンズ体５の凸レンズ状部８により集光された太陽光Ａが内筒７からなる加熱板上において焦点を結ぶことにより、この内筒７が高温に加熱されて風洞４内の温度が上昇するとともに、この温度が外筒６と内筒７との間において維持される。このため、風洞４内の空気密度が低下し、風洞４の内部と外気との温度差に応じて上昇気流Ｂが発生し、これに対応して風洞４の下端部開口部から風洞４内に外気が連続的に導入されるとともに、その上端開口部から風車３の設置部に向けて上記上昇気流Ｂが案内されることになる。   In the above configuration, when sunlight A is applied to the wind tunnel 4 installed along the south side wall surface of the building 1, the sunlight A collected by the convex lens-shaped portion 8 of the lens body 5 is composed of the inner cylinder 7. By focusing on the heating plate, the inner cylinder 7 is heated to a high temperature, the temperature in the wind tunnel 4 rises, and this temperature is maintained between the outer cylinder 6 and the inner cylinder 7. For this reason, the air density in the wind tunnel 4 is reduced, and an ascending air flow B is generated according to the temperature difference between the inside of the wind tunnel 4 and the outside air. Outside air is continuously introduced, and the upward air flow B is guided from the upper end opening toward the installation portion of the wind turbine 3.

そして、上記風車３を構成するダリウスロータ１１およびサポニウスロータ１２，１３がビル１の屋上に吹き付けられた風Ｃによって回転駆動されるとともに、風洞４により案内された上記上昇気流Ｂに応じて下方のサポニウスロータ１３が回転駆動されることにより、上記垂直軸１０が強い力で回転駆動されて上記発電機２による発電が効率よく行われることになる。すなわち、ビル１の屋上に吹き付けられた風Ｃのエネルギーと、風洞４に照射された太陽光Ａのエネルギーとの両方を有効に利用して上記風車３を高速で回転駆動することにより、発電機２の発電効率を効果的に向上させることができる。   The Darrieus rotor 11 and the Saponius rotors 12 and 13 constituting the wind turbine 3 are driven to rotate by the wind C blown on the roof of the building 1 and are moved downward according to the updraft B guided by the wind tunnel 4. The saponius rotor 13 is rotationally driven, so that the vertical shaft 10 is rotationally driven with a strong force, and the power generation by the generator 2 is efficiently performed. That is, the wind turbine 3 is driven to rotate at high speed by effectively using both the energy of the wind C blown on the roof of the building 1 and the energy of the sunlight A irradiated to the wind tunnel 4, thereby generating a generator. The power generation efficiency of 2 can be effectively improved.

特に、上記実施形態に示すように、風洞４を構成する外筒６および内筒７の直径を上端部に至る程小さくして風洞４を上窄まりに形成した場合には、風洞４内において発生した上昇気流Ｂが上昇するのに伴って流速が早くなるため、上記風車３を、より高速で回転駆動できるという利点がある。また、上記実施形態では、風洞４の下端部を南側に向けて開口したため、ビル１の壁面に向けて吹き付けたビル風を風洞４内に効率よく取り込むことにより、このビル風を有効に利用することができる。   In particular, as shown in the above embodiment, when the diameter of the outer cylinder 6 and the inner cylinder 7 constituting the wind tunnel 4 is reduced so as to reach the upper end portion, As the generated ascending air flow B rises, the flow velocity becomes faster, so there is an advantage that the windmill 3 can be rotationally driven at a higher speed. Moreover, in the said embodiment, since the lower end part of the wind tunnel 4 opened toward the south side, this building wind is effectively utilized by taking in the building wind sprayed toward the wall surface of the building 1 in the wind tunnel 4 efficiently. be able to.

図６に示すように、風洞４内において発生した上昇気流Ｂを旋回させるスパイラル状のガイド羽根１４を、風洞４の内部（具体的には上記加熱板を構成する内筒７の内壁面）に設けた構造としてもよい。このように構成した場合には、上記レンズ体５の凸レンズ状部８により集光された太陽光のエネルギーに応じて発生した上昇気流Ｂを風洞４内においてスムーズに流動させることにより、上記風車３を効率よく回転駆動することができるという利点がある。   As shown in FIG. 6, spiral guide blades 14 that swirl upward airflow B generated in the wind tunnel 4 are disposed inside the wind tunnel 4 (specifically, the inner wall surface of the inner cylinder 7 that constitutes the heating plate). It is good also as the structure provided. When configured in this way, the wind turbine 3 is caused to flow smoothly in the wind tunnel 4 by the rising air flow B generated according to the energy of sunlight collected by the convex lens-shaped portion 8 of the lens body 5. Can be efficiently rotated.

また、図７に示すように、屋上の貯留槽に貯留された水道水等を、上記内筒７からなる加熱板に向けて注水する注水管および注水ノズル等を有する注水手段１５を設け、上記内筒７の温度が充分に高くなったことが図外の温度センサにより検出された時点で、上記注水手段１５から加熱板（内筒７）に向けて注水することにより、この注水された水道水等を気化させて風洞４内に蒸気を発生させるように構成してもよい。このように太陽光Ａにより加熱された内筒７の温度を利用して水蒸気を発生させるように構成した場合には、この水蒸気の膨張作用により風洞４内における上昇気流Ｂを充分に強化して、さらに効率よく上記風車３を回転駆動することができる。特に、上記ガイド羽根１４と注水手段１５との両方を風洞４に設けた構造とした場合には、上記上昇気流Ｂを、より効果的に強化できるという利点がある。   Moreover, as shown in FIG. 7, the water injection means 15 which has the water injection pipe and water injection nozzle etc. which inject the tap water etc. which were stored by the storage tank of the roof toward the heating plate which consists of the said inner cylinder 7 is provided, When it is detected by a temperature sensor (not shown) that the temperature of the inner cylinder 7 has become sufficiently high, water is poured from the water pouring means 15 toward the heating plate (inner cylinder 7), whereby this water is poured. You may comprise so that water etc. may be vaporized and a vapor | steam may be generated in the wind tunnel 4. FIG. Thus, when it comprises so that water vapor | steam may be generated using the temperature of the inner cylinder 7 heated by sunlight A, the ascending air flow B in the wind tunnel 4 is sufficiently strengthened by the expansion action of this water vapor. Further, the windmill 3 can be driven to rotate more efficiently. In particular, when both the guide blade 14 and the water injection means 15 are provided in the wind tunnel 4, there is an advantage that the updraft B can be strengthened more effectively.

さらに、上記レンズ体５が設置された風洞４の上端部から下端部に至る略全域に亘って複数の注水手段１５を一定間隔で配設するとともに、上端または下端の注水手段１５から順番に上記水道水等を内筒７に向けて吹き付け、あるいは図外の温度センサの検出信号に応じて温度が高いと判定された個所を選定して水道水等を吹き付けることにより、連続的に水蒸気を発生させるように構成することも可能である。このように構成した場合には、上記風洞４に照射された太陽光Ａのエネルギーを有効に利用して長期間に亘り上昇気流Ｂを強化することができるため、発電効率を効果的に向上させることができる。   Furthermore, a plurality of water injection means 15 are arranged at regular intervals over substantially the entire region from the upper end portion to the lower end portion of the wind tunnel 4 in which the lens body 5 is installed, and the water injection means 15 at the upper end or the lower end are arranged in order from the above. Steam is continuously generated by spraying tap water or the like toward the inner cylinder 7 or by spraying tap water or the like by selecting a location determined to be high according to the detection signal of the temperature sensor (not shown). It is also possible to configure it. When configured in this way, the energy of solar A irradiated to the wind tunnel 4 can be effectively used to strengthen the updraft B over a long period of time, thus effectively improving power generation efficiency. be able to.

なお、上記風洞４を構成する外筒６の南側に位置する壁面にのみ上記レンズ体５を設置した構造としてもよいが、図８に示すように、風洞４の背面側に反射板１６を設置するとともに、この風洞４を構成する外筒６の全周に上記レンズ体５を設置し、上記反射板１６を利用して風洞４の背面側にも太陽光Ａを照射するように構成してもよい。このように構成した場合には、ビル１の壁面等に向けて照射された太陽光のエネルギーを効果的に利用して、より強い上昇気流Ｂを発生させることができるという利点がある。   Although the lens body 5 may be installed only on the wall surface located on the south side of the outer cylinder 6 constituting the wind tunnel 4, a reflector 16 is installed on the back side of the wind tunnel 4 as shown in FIG. At the same time, the lens body 5 is installed on the entire circumference of the outer cylinder 6 constituting the wind tunnel 4, and the reflector A is used to irradiate the back side of the wind tunnel 4 with sunlight A. Also good. When comprised in this way, there exists an advantage that the stronger upward airflow B can be generated using the energy of the sunlight irradiated toward the wall surface etc. of the building 1 effectively.

また、ビル１の屋上に発電機２および風車３を設置するとともに、ビル１の壁面に沿って風洞４を設置してなる上記実施形態に代え、図９に示すように、風の強い山１７の頂に発電機２および風車３を設置するとともに、山１７の南側斜面に沿って風洞４ａを設置し、この風洞４ａにより山麓付近の風を風車３の設置部に向けて案内するように構成してもよい。この場合においても、上記風洞４ａに設けられたレンズ体５により集光された太陽光のエネルギーを利用して風洞４ａの内部に設けられた加熱板を加熱することにより上昇気流Ｂを発生させることができる。したがって、この上昇気流Ｂと、山頂に吹き付けた風Ｃとの両方で上記風車３を高速で回転させることにより、上記発電機２の発電効率を効果的に向上させることができる。   Further, in place of the above-described embodiment in which the generator 2 and the windmill 3 are installed on the roof of the building 1 and the wind tunnel 4 is installed along the wall surface of the building 1, as shown in FIG. The generator 2 and the windmill 3 are installed on the top of the mountain, and the wind tunnel 4a is installed along the south slope of the mountain 17, and the wind tunnel 4a guides the wind near the foot of the mountain toward the installation section of the windmill 3. May be. Even in this case, the rising airflow B is generated by heating the heating plate provided inside the wind tunnel 4a using the energy of the sunlight collected by the lens body 5 provided in the wind tunnel 4a. Can do. Therefore, the power generation efficiency of the generator 2 can be effectively improved by rotating the windmill 3 at a high speed with both the rising airflow B and the wind C blown on the mountaintop.

なお、上記実施形態では、ダリウスロータ１１およびサポニウスロータ１２，１３を有する風車３を、ビル１の屋上、または山頂等の高所に設置した例について説明したが、これに限らず、通常のプロペラ型風車またはガイドベーン付クロスフロー型風車を用いたり、あるいはこれらを組み合わせたりすることも可能である。例えば、図１０に示すように、高所に吹き付ける風Ｃを利用する風車３の下方にプロペラ型風車１８を設置するとともに、このプロペラ型風車１８に地上付近の外気を上昇気流Ｂとして案内する風洞４ｂを設けた構造としてもよい。   In the above-described embodiment, the example in which the windmill 3 having the Darius rotor 11 and the Saponius rotors 12 and 13 is installed on the rooftop of the building 1 or at a high place such as the top of a mountain has been described. It is also possible to use a propeller type wind turbine or a cross flow type wind turbine with guide vanes, or a combination thereof. For example, as shown in FIG. 10, a propeller type windmill 18 is installed below a windmill 3 that uses a wind C blown at a high place, and a wind tunnel that guides outside air near the ground as an updraft B to the propeller type windmill 18. It is good also as a structure which provided 4b.
