Description

本発明は、風力を動力源として駆動力を得る風力駆動装置に関する。   The present invention relates to a wind power driving apparatus that obtains driving force using wind power as a power source.

従来、風力駆動装置としては、下記特許文献１に示すように、内部が吸気口から排気口へ向かって縮径した円筒内に、複数の羽根車と該羽根車に連結した複数の発電機を設けた風力駆動装置が知られている。   Conventionally, as a wind power drive device, as shown in the following Patent Document 1, a plurality of impellers and a plurality of generators connected to the impellers are provided in a cylinder whose inside is reduced in diameter from the intake port toward the exhaust port. The provided wind drive device is known.

特開平１１−６２８１１号公報JP-A-11-62811

かかる従来の風力駆動装置においては、吸気口から導入された流入空気により複数の羽根車が駆動されるため、流入空気を効率よく羽根車の駆動力に変換し得る。   In such a conventional wind power drive device, since the plurality of impellers are driven by the inflow air introduced from the intake port, the inflow air can be efficiently converted into the driving force of the impeller.

しかしながら、複数の羽根車のそれぞれに発電機を設ける場合には、装置構成が複雑になり、製造コストが嵩むという問題がある。さらに、風上となる吸気口側の羽根車の回転数が極端に大きくなり、この部分の使用負荷が大きく破損し易いという問題がある。   However, when a generator is provided for each of the plurality of impellers, there is a problem that the device configuration becomes complicated and the manufacturing cost increases. Furthermore, there is a problem that the rotational speed of the impeller on the intake port side, which is on the windward side, becomes extremely large, and the use load at this portion is large and easily damaged.

そこで本発明は、単純な装置構成でも効率よく駆動力を得ることができ、耐久性に優れた風力駆動装置を提供することを目的とする。   Accordingly, an object of the present invention is to provide a wind power drive device that can efficiently obtain a driving force even with a simple device configuration and is excellent in durability.

第１発明の風力駆動装置は、
風力を動力源として駆動力を得る風力駆動装置であって、
一端側に吸気口と他端側に排気口とを有する角筒状の筐体と、
前記筐体の内部空間で該筐体の一端から他端へ向かって延びる１本の回転軸と、
前記吸気口と前記排気口との間で、前記該回転軸に設けられた複数の羽根車とを備え、
前記筐体の一端から他端に向かう各断面において、前記内部空間に対して各羽根車が占める割合が増大するように、該内部空間は、前記吸気口から前記排気口に向かって断面積が小さく形成されていることを特徴とする。 The wind power drive device of the first invention is
A wind power drive device that obtains driving force using wind power as a power source,
A rectangular tubular housing having an inlet on one end and an exhaust on the other end;
One rotating shaft extending from one end to the other end of the casing in the internal space of the casing;
A plurality of impellers provided on the rotating shaft between the intake port and the exhaust port ;
In each section extending from the end of the previous Kikatamitai the other end, as the ratio occupied by the impeller to the internal space is increased, the internal space, the cross-sectional area toward the outlet from the inlet port Is formed small .

第１発明の風力駆動装置によれば、１本の回転軸を同軸心として、これに複数の羽根車が設けられている。そのため、単純な装置構成で製造コストが嵩むこともない。   According to the wind power drive device of the first invention, a plurality of impellers are provided on a single rotating shaft as a coaxial center. Therefore, the manufacturing cost does not increase with a simple device configuration.

一方で、１本の回転軸に複数の羽根車を設けた場合には、風上となる吸気口側の羽根車の回転数が大きく、風下となる排気口側の羽根車の回転数が小さくなり、回転差によるねじれが回転軸に生じ得る。   On the other hand, when a plurality of impellers are provided on one rotating shaft, the rotational speed of the impeller on the air inlet side that is on the windward is large, and the rotational speed of the impeller on the exhaust port side that is on the lee side is small. Thus, a twist due to a rotation difference can occur in the rotation shaft.

しかしながら、複数の羽根車を、筐体の一端から他端に向かう各断面において、内部空間に対して各羽根車が占める割合が増大することで、吸気口側の羽根車の回転数の増大を抑制すると共に排気口側の羽根車の回転数の低下を抑制することができ、１本の回転軸に複数の羽根車を設けた場合にも、回転軸に回転差によるねじれが生じることを防止することができる。   However, in each cross section from one end of the housing to the other end of the plurality of impellers, the ratio of each impeller to the internal space increases, thereby increasing the rotation speed of the intake-side impeller. It is possible to suppress the reduction in the rotational speed of the impeller on the exhaust port side, and even when a plurality of impellers are provided on a single rotating shaft, the rotating shaft is prevented from being twisted due to a rotational difference. can do.

さらに、吸気口側の羽根車の回転数の増大を抑制することができ、この部分の使用負荷を抑えて、装置自体の耐久性を高めることができる。   Furthermore, an increase in the number of rotations of the impeller on the intake port side can be suppressed, the use load of this portion can be suppressed, and the durability of the device itself can be enhanced.

このように、本発明の風力駆動装置によれば、単純な装置構成でも効率よく駆動力を得ることができ、高い耐久性を実現することができる。   Thus, according to the wind power drive device of the present invention, a drive force can be obtained efficiently even with a simple device configuration, and high durability can be realized.

さらに、本発明の風力駆動装置によれば、筐体はその内部空間が吸気口から排気口に向かって断面積を小さくすることで、回転軸に同一の大きさの羽根車を複数設けた場合にも、筐体の一端から他端に向かう各断面において、内部空間に対して各羽根車が占める割合を増大させることができる。これにより、吸気口側から導入された流入空気は、排気口側でその流路を絞られるため、回転数が低下し易い排気口側の羽根車の回転数を増大させることができ、１本の回転軸に複数の羽根車を設けた場合にも、回転軸に回転差によるねじれが生じることを防止することができる。 Furthermore, according to the wind power drive device of the present invention, when the casing has a plurality of impellers of the same size on the rotating shaft by reducing the cross-sectional area of the internal space from the intake port to the exhaust port. In addition, in each cross section from the one end to the other end of the housing, the ratio of each impeller to the internal space can be increased. Thereby, since the flow path of the inflow air introduced from the intake port side is restricted on the exhaust port side, the rotation number of the impeller on the exhaust port side where the rotation number tends to decrease can be increased. Even when a plurality of impellers are provided on the rotating shaft, it is possible to prevent the rotating shaft from being twisted due to a rotational difference.

第２発明の風力駆動装置は、第１発明において、
前記筐体には、前記排気口側に内圧に応じて開放する可動弁が設けられていることを特徴とする。 The wind power drive device of the second invention is the first invention,
The casing is provided with a movable valve that opens on the exhaust port side in accordance with an internal pressure.

第２発明の風力駆動装置によれば、筐体はその内部空間が吸気口から排気口に向かって断面積が小さくなるために、吸気口から導入された空気が排気口側でその流路が絞られ、内圧が上昇し得る。これに対して、過度に内圧が上昇した場合に可動弁を開放することで、排気口側の羽根車の回転数が増大し過ぎることを回避することができ、１本の回転軸に複数の羽根車を設けた場合にも、回転軸に回転差によるねじれが生じることを防止することができる。 According to the wind power drive device of the second aspect of the invention, since the internal space of the casing becomes smaller in cross section from the air inlet to the air outlet, the air introduced from the air inlet has its flow path on the air outlet side. It can be squeezed and the internal pressure can rise. On the other hand, by opening the movable valve when the internal pressure rises excessively, it is possible to avoid an excessive increase in the rotational speed of the impeller on the exhaust port side, and a plurality of rotations on one rotating shaft. Even when the impeller is provided, it is possible to prevent the rotation shaft from being twisted due to the rotation difference.

第３発明の風力駆動装置は、第１または第２発明において、
前記筐体の内部空間には、前記排気口側の角部に前記吸気口から導入された流入空気を該排気口側の前記羽根車に偏向する偏向板が設けられていることを特徴とする。 The wind power drive device of the third invention is the first or second invention,
The internal space of the housing is provided with a deflecting plate for deflecting the inflow air introduced from the intake port to the impeller on the exhaust port side at a corner portion on the exhaust port side. .

第３発明の風力駆動装置によれば、排気口側の角部に偏向板を設けて吸気口から導入された風を羽根車に偏向することで、回転数が低下し易い排気口側の羽根車の回転数を増大させることができ、１本の回転軸に複数の羽根車を設けた場合にも、回転軸に回転差によるねじれが生じることを防止することができる。 According to the wind power drive device of the third aspect of the present invention, the deflector plate is provided at the corner on the exhaust port side, and the wind introduced from the intake port is deflected to the impeller, whereby the blade on the exhaust port side whose rotation speed is likely to decrease. The number of rotations of the vehicle can be increased, and even when a plurality of impellers are provided on one rotation shaft, it is possible to prevent the rotation shaft from being twisted due to a rotation difference.

図１および図２に示すように、本実施形態の風力駆動装置は、一端側に吸気口１と他端側に排気口２とを有する角筒状の筐体３と、筐体３の内部空間４で筐体３の一端から他端へ向かって延びる１本の回転軸５と、回転軸５に設けられた複数の羽根車１１，１２，１３，１４，１５と備え、吸気口１から内部空間４内に導入された流入空気の風力により複数の羽根車１１，１２，１３，１４，１５を動力源として、図示しない発電機を駆動するものである。   As shown in FIG. 1 and FIG. 2, the wind power drive device of the present embodiment includes a rectangular tube-shaped housing 3 having an intake port 1 on one end side and an exhaust port 2 on the other end side, and an interior of the housing 3. In the space 4, there is provided one rotating shaft 5 extending from one end of the housing 3 toward the other end, and a plurality of impellers 11, 12, 13, 14, 15 provided on the rotating shaft 5. A generator (not shown) is driven by wind power of inflow air introduced into the internal space 4 using the impellers 11, 12, 13, 14, and 15 as power sources.

吸気口１は、筐体３の一端の開口部と同一であり、排気口２は、筐体３の他端側の側面に形成された開口部であって、筐体３の他端の開口部を覆うフード６により内部空間４と連通するように構成される。   The air inlet 1 is the same as the opening at one end of the housing 3, and the air outlet 2 is an opening formed on the side surface at the other end of the housing 3, and the opening at the other end of the housing 3. The hood 6 covering the part is configured to communicate with the internal space 4.

すなわち、排気口２は、筐体３の他端の開口部とは別に設けられて、内部空間４から筐体３の他端へ向かって流れる流入空気をフード６により排気口で導入されるようになっている。   That is, the exhaust port 2 is provided separately from the opening at the other end of the housing 3, so that inflow air flowing from the internal space 4 toward the other end of the housing 3 is introduced by the hood 6 at the exhaust port. It has become.

なお、排気口２は、筐体３の下側面に設けられる場合に限られず、風力駆動装置が搭載される機械・機器・システム（例えば、車両、屋外のポール）などに応じて、上側面や左右側面のいずれか一方または両方に設けられてもよい。さらに、フード６を設けずに、筐体３の他端の開口部を排気口としてもよい。   The exhaust port 2 is not limited to the case provided on the lower side surface of the housing 3, and the upper side surface or the exhaust port 2 may be changed depending on the machine / equipment / system (for example, vehicle, outdoor pole) on which the wind drive device is mounted. It may be provided on either one or both of the left and right side surfaces. Furthermore, it is good also considering the opening part of the other end of the housing | casing 3 as an exhaust port, without providing the hood 6. FIG.

内部空間４は、筐体３の内部を仕切板７により分割した空間であって、仕切板７は、吸気口１の下部を一端として、他端側を底上げするように筐体３の内部に配置される。これにより、内部空間４は、吸気口１から排気口２に向かって下側面がスロープ状に形成され、徐々にその断面が小さくなる。   The internal space 4 is a space in which the interior of the housing 3 is divided by a partition plate 7. The partition plate 7 is placed inside the housing 3 so that the lower end of the intake port 1 is one end and the other end is raised to the bottom. Be placed. Thereby, the lower surface of the internal space 4 is formed in a slope shape from the intake port 1 toward the exhaust port 2, and its cross section gradually decreases.

仕切板７には、その排気口２側の位置に可動弁８が設けられており、可動弁８は、図示しないねじりバネを噛ませたヒンジにより閉塞位置に付勢され、内圧（内部空間内の圧力）に応じて開放する。すなわち、可動弁８は、内圧が高まるにつれて徐々に開放し、さらに内圧が高まった場合には全開状態となる。これにより、内圧をある程度一定に保つと共に、内圧の急激な上昇を抑制するバッファとして機能する。   The partition plate 7 is provided with a movable valve 8 at a position on the exhaust port 2 side, and the movable valve 8 is urged to a closed position by a hinge that engages a torsion spring (not shown), and the internal pressure (inside the internal space) According to the pressure). That is, the movable valve 8 is gradually opened as the internal pressure increases, and becomes fully open when the internal pressure further increases. As a result, the internal pressure is kept constant to a certain extent and functions as a buffer that suppresses a rapid increase in internal pressure.

回転軸５は、筐体３の内部空間４で仕切板７と平行に設けられた軸体であって、その一端および他端が筐体３の内壁に渡した支持柱８Ａおよび８Ｂに軸着されている。回転軸５と支持柱８Ａおよび８Ｂとの軸着位置には、図示しないベアリングが設けられており、回転軸５はスムーズに回転するようになっている。なお、この回転軸５に図示しない発電機が接続されて、回転軸５の回転数に応じた発電が実現される。   The rotation shaft 5 is a shaft body provided in parallel with the partition plate 7 in the internal space 4 of the housing 3, and one end and the other end of the rotation shaft 5 are attached to the support pillars 8 </ b> A and 8 </ b> B that extend to the inner wall of the housing 3. Has been. A bearing (not shown) is provided at a shaft attachment position between the rotating shaft 5 and the support columns 8A and 8B so that the rotating shaft 5 rotates smoothly. A generator (not shown) is connected to the rotating shaft 5 to realize power generation according to the rotational speed of the rotating shaft 5.

羽根車１１，１２，１３，１４，１５は、それぞれ同一形状の羽根車であって、吸気口１から排気口２までの間で回転軸５に等間隔に固定されている。さらに、排気口２側の羽根車１４および１５の手前には、それぞれ流入空気を羽根車１４，１５に偏向する偏向板９Ａおよび９Ｂが設けられている。   The impellers 11, 12, 13, 14, and 15 are impellers having the same shape, and are fixed to the rotary shaft 5 at equal intervals between the intake port 1 and the exhaust port 2. Further, deflection plates 9A and 9B for deflecting the incoming air to the impellers 14 and 15 are provided in front of the impellers 14 and 15 on the exhaust port 2 side, respectively.

偏向板９Ａは、内部空間４の下側の２つの角部の一方に設けられ、偏向板９Ｂは、内部空間４の上側の２つの角部の一方で、偏向板９Ａと対向する側に設けられる。これにより、角部を通して羽根車１１，１２，１３，１４，１５に当ることなく流れる流入空気を羽根車１４，１５に偏向させて、その回転駆動力に利用することができる。   The deflecting plate 9A is provided at one of the two lower corners of the internal space 4, and the deflecting plate 9B is provided at one of the two upper corners of the internal space 4 on the side facing the deflecting plate 9A. It is done. Thereby, the inflowing air that flows without hitting the impellers 11, 12, 13, 14, and 15 through the corners can be deflected to the impellers 14 and 15 and used for the rotational driving force.

ここで、図３を参照して、内部空間４と羽根車１１，１２，１３，１４，１５との関係について補足する。図３（ａ）〜図３（ｃ）は、それぞれ図２のＩＩＩＡ−ＩＩＩＡ線断面図、ＩＩＩＢ−ＩＩＩＢ線断面図、ＩＩＩＣ−ＩＩＩＣ線断面図である。   Here, with reference to FIG. 3, it supplements about the relationship between the interior space 4 and the impellers 11, 12, 13, 14, and 15. FIG. 3A to 3C are a cross-sectional view taken along line IIIA-IIIA, a cross-sectional view taken along line IIIB-IIIB, and a cross-sectional view taken along line IIIC-IIIC in FIG.

まず、図３（ａ）に示すように、吸気口１側の羽根車１１の回転面積Ａ１は、内部空間４の断面積に対して約半分である。これに対して、図３（ｂ）および（ｃ）に示すように、（羽根車１１，１２，１３，１４，１５の形状が同一で回転面積も同一で、）排気口側に行くほど内部空間４の断面積が小さくなるため、内部空間４の断面積に対する羽根車１３および１５の回転面積Ａ３およびＡ５が増大する。   First, as shown in FIG. 3A, the rotational area A <b> 1 of the impeller 11 on the intake port 1 side is about half of the cross-sectional area of the internal space 4. On the other hand, as shown in FIGS. 3 (b) and 3 (c), the inner side is closer to the exhaust port side (the shape of the impeller 11, 12, 13, 14, 15 is the same and the rotation area is the same). Since the sectional area of the space 4 is reduced, the rotational areas A3 and A5 of the impellers 13 and 15 with respect to the sectional area of the inner space 4 are increased.

これにより、風上となる吸気口１側の羽根車１１の回転数が大きく、風下となる排気口２側の羽根車１５の回転数が小さくなり、回転差によるねじれが回転軸５に生じることを防止することができる。   As a result, the rotational speed of the impeller 11 on the intake port 1 side, which is on the windward side, is large, and the rotational speed of the impeller 15 on the exhaust port 2 side, which is on the leeward side, is small. Can be prevented.

すなわち、１本の回転軸５を同軸心として、これに複数の羽根車１１，１２，１３，１４，１５を設けた場合には、風上となる吸気口１側の羽根車１１の回転数が大きく、風下となる排気口２側の羽根車１５の回転数が小さくなり、回転差によるねじれが回転軸５に生じるが、複数の羽根車１１，１２，１３，１４，１５を、筐体３の一端から他端に向かう各断面において、内部空間４に対して各羽根車１１，１２，１３，１４，１５が占める割合が増大するようにすることで、吸気口１側の羽根車１１の回転数の増大を抑制すると共に排気口２側の羽根車１５の回転数の低下を抑制することができ、１本の回転軸５に複数の羽根車１１，１２，１３，１４，１５を設けた場合にも、回転軸５に回転差によるねじれが生じることを防止することができる。   That is, when a single rotating shaft 5 is used as a coaxial center and a plurality of impellers 11, 12, 13, 14, and 15 are provided on the same, the rotational speed of the impeller 11 on the intake port 1 side that becomes the windward side. Is large, the rotational speed of the impeller 15 on the exhaust port 2 side that is leeward is small, and a twist due to a rotational difference occurs in the rotary shaft 5, but the plurality of impellers 11, 12, 13, 14, 15 are 3, the ratio of the impellers 11, 12, 13, 14, 15 occupying the internal space 4 is increased in each cross section from one end to the other end, whereby the impeller 11 on the intake port 1 side is increased. And a decrease in the rotational speed of the impeller 15 on the exhaust port 2 side can be suppressed, and a plurality of impellers 11, 12, 13, 14, 15 can be connected to one rotary shaft 5. Even when it is provided, it is possible to prevent the rotating shaft 5 from being twisted due to a rotational difference. Can.

さらに、吸気口１側の羽根車１１の回転数の増大を抑制することができ、この部分の使用負荷を抑えて、装置自体の耐久性を高めることができる。   Furthermore, an increase in the number of revolutions of the impeller 11 on the intake port 1 side can be suppressed, and the use load at this portion can be suppressed, and the durability of the apparatus itself can be enhanced.

このように、本実施形態の風力駆動装置によれば、１本の回転軸５に複数の羽根車１１，１２，１３，１４，１５を設けた単純な装置構成でも効率よく駆動力を得ることができ、高い耐久性を実現することができる。   Thus, according to the wind power drive device of the present embodiment, a driving force can be obtained efficiently even with a simple device configuration in which a plurality of impellers 11, 12, 13, 14, 15 are provided on one rotating shaft 5. And high durability can be realized.

なお、本実施形態では、羽根車１１，１２，１３，１４，１５を同一形状として、仕切板７により内部空間４を排気口２側で絞る構成としたが、筐体３の一端から他端に向かう各断面において、内部空間４に対して各羽根車１１，１２，１３，１４，１５が占める割合が増大する構成はこれに限定されるものではない。   In this embodiment, the impellers 11, 12, 13, 14, and 15 have the same shape, and the partition plate 7 restricts the internal space 4 on the exhaust port 2 side. The configuration in which the ratio of the impellers 11, 12, 13, 14, and 15 to the internal space 4 is not limited to this.

例えば、内部空間４は、仕切板７等と設けないストレートな形状としつつ、羽根車１１，１２，１３，１４，１５を（同一形状ではなく）吸気口１から排気口２に向かって徐々に大きな形状のものを用いるようにしてもよい。   For example, the internal space 4 is formed in a straight shape not provided with the partition plate 7 or the like, and the impellers 11, 12, 13, 14, and 15 are gradually moved from the intake port 1 toward the exhaust port 2 (not the same shape). A large shape may be used.

また、本実施形態で内部空間４は、角筒型の筐体３の下側面のみを絞っているが、これに限らず、上面および左右側面の一部または全部を絞ってもよい。   Further, in the present embodiment, the inner space 4 narrows down only the lower side surface of the rectangular tube-shaped housing 3, but this is not restrictive, and part or all of the upper surface and the left and right side surfaces may be narrowed down.
