上記のように構成された実施の形態１の流体エネルギ回収装置は、ケーシング１２の流路１３が河川などに浸漬される。そして、流体としての水が流路１３を流れる。この際、ケーシング１２の入側開口部１２ａ側では、流体案内部１４と導流体板１５と間に水が流れる。この水は、流体案内部１４が入側開口部１２ａ側から回転翼１１側までに至る縦断面面積が回転翼１１の羽根部３の流体を受ける側に向かって小さくなるテーパ状にて形成されている。そして、回転翼１１の羽根部３がそれぞれ水の流れを受けて回転するこれに伴い、上部板体１および下部板体２は第１および第２の中心点Ｘ、Ｙを中心に回転する。そして、この上部板体１の回転エネルギを回収部４にて回収して、発電等を行う。そして、ケーシング１２の出側開口部１２ｂから水は排出される。   In the fluid energy recovery apparatus of the first embodiment configured as described above, the flow path 13 of the casing 12 is immersed in a river or the like. Then, water as a fluid flows through the flow path 13. At this time, water flows between the fluid guide 14 and the fluid guide plate 15 on the inlet side opening 12 a side of the casing 12. The water is formed in a tapered shape in which the fluid guide portion 14 has a longitudinal cross-sectional area from the inlet opening 12a side to the rotor blade 11 side that decreases toward the fluid receiving side of the blade portion 3 of the rotor blade 11. ing. As the blade portion 3 of the rotor blade 11 rotates by receiving the flow of water, the upper plate 1 and the lower plate 2 rotate around the first and second center points X and Y. The rotational energy of the upper plate 1 is recovered by the recovery unit 4 to generate power. And water is discharged | emitted from the exit side opening part 12b of the casing 12. FIG.

このように、ケーシング１２内の水の流れは図１において矢印にて示すように、出側開口部１２ｂから排出されるが、一部の水は回転翼１１の羽根部３の回転によりそのままケーシング１２内を移動して、ケーシング１２の流体案内部１４の流体の流れ込む側の相反する側の溜まり部分Ｚに至る場合がある。その際、溜まり部分Ｚに水が残存すると、回転翼１１の回転に支障となる。しかしながら、本発明は、回転翼１１の流体が流れ込む側とケーシング１２の側壁１２ｃとの幅方向の間隔Ｈ１より、回転翼１１の流体が流れ込む側の相反する側とケーシング１２の側壁１２ｄとの幅方向の間隔Ｈ２が広く形成されている。よって、回転翼１１の流体の流れ込む側とケーシング１２の側壁１２ｃとの間を流れることができる水の量より、回転翼１１の流体の流れ込む側の相反する側とケーシング１２の側壁１２ｄとの間を流れることができる水の量の方が多い。このため、溜まり部分Ｚに至った水は、回転翼１１の流体の流れ込む側の相反する側とケーシング１２の側壁１２ｄと間から排出されやすい。よって、溜まり部分Ｚに水が残存することによる回転翼１１の回転に支障が生じることを防止することができる。   As described above, the flow of water in the casing 12 is discharged from the outlet side opening 12b as indicated by an arrow in FIG. In some cases, the fluid guide portion 14 of the casing 12 moves to the pool portion Z on the opposite side of the fluid flow side. At this time, if water remains in the pool portion Z, the rotation of the rotor blade 11 is hindered. However, according to the present invention, the width between the side of the rotor blade 11 into which the fluid flows and the side wall 12d of the casing 12 from the width H1 between the side of the rotor blade 11 into which the fluid flows and the side wall 12c of the casing 12 in the width direction. The direction interval H2 is wide. Therefore, the amount of water that can flow between the fluid flowing side of the rotor blade 11 and the side wall 12c of the casing 12 is larger than the opposite side of the rotor blade 11 on the fluid flowing side and the side wall 12d of the casing 12. There is more water that can flow through. For this reason, the water reaching the reservoir portion Z is likely to be discharged from between the opposite side of the rotor blade 11 where the fluid flows and the side wall 12 d of the casing 12. Therefore, it is possible to prevent the rotation of the rotor blade 11 from being hindered by water remaining in the pool portion Z.

また、ここでは１つの回転翼１１を備える例を示したが、これに限られることはなく、例えば図４に示すように、一対の回転翼１０、１１をケーシング１２内に備えた場合においても同様に構成することができる。図４において、上記実施の形態１と同様の部分は同一符号を付して説明を省略する。流体案内部１４０は、ケーシング１２に形成された流路１３の入側開口部１２ａ側から一対の回転翼１０、１１側までに至る縦断面面積が一対の回転翼１０、１１に向かって小さくなるように形成されている。回転翼１０は矢印Ｂの方向に回転するものである。そして、各回転翼１０、１１とケーシング１２の側壁１２ｃ、１２ｄとのそれぞれの幅方向の間隔Ｈ３、Ｈ４は、一対の回転翼１０、１１間のケーシング１２の幅方向の半分位置Ｑからのそれぞれの幅方向の間隔Ｈ５、Ｈ６より広く形成されている。   In addition, although an example in which one rotor blade 11 is provided is shown here, the present invention is not limited to this. For example, as illustrated in FIG. 4, even when a pair of rotor blades 10 and 11 are provided in the casing 12. It can be configured similarly. In FIG. 4, the same parts as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. The fluid guide part 140 has a longitudinal cross-sectional area from the inlet side opening 12 a side of the flow path 13 formed in the casing 12 to the pair of rotor blades 10 and 11, and decreases toward the pair of rotor blades 10 and 11. It is formed as follows. The rotary blade 10 rotates in the direction of arrow B. The widths H3 and H4 in the width direction between the rotor blades 10 and 11 and the side walls 12c and 12d of the casing 12 are respectively determined from the half position Q in the width direction of the casing 12 between the pair of rotor blades 10 and 11. Are formed wider than the intervals H5 and H6 in the width direction.

そして、導流体板１５０は、流体案内部１４０内を流路１３の流体の流れる方向と同一方向で仕切るように配設されたものである。一対の導流体板１５０の間隔は、入側開口部１２ａ側の間隔および一対の回転翼１０、１１側の間隔より入側開口部１２ａから一対の回転翼１０、１１までの間の間隔が広く流線形にて形成されている。また、導流体板１５０は、一対の回転翼１０、１１側の端部が一対の回転翼１０、１１間に至るように形成されている。   The fluid guide plate 150 is disposed so as to partition the inside of the fluid guide portion 140 in the same direction as the direction of fluid flow in the flow path 13. The gap between the pair of fluid guide plates 150 is wider between the inlet opening 12a and the pair of rotor blades 10, 11 than the gap on the inlet opening 12a side and the pair of rotor blades 10, 11 side. It is formed by streamline. The fluid guide plate 150 is formed so that the end portions on the pair of rotor blades 10 and 11 reach between the pair of rotor blades 10 and 11.

よって、上記実施の形態１と同様に、水の流れは図４に示す矢印のようになる。そして、一対の回転翼１０、１１間を流れることができる水の量より、各回転翼１０、１１とケーシング１２の側壁１２ｅ、１２ｆとの間を流れることができる水の量の方が多い。このため、溜まり部分Ｚに至った水は、各回転翼１０、１１とケーシング１２の側壁１２ｅ、１２ｆと間から排出されやすい。よって、溜まり部分Ｚに水が残存することによる回転翼１０、１１の回転に支障が生じることを防止することができる。   Therefore, as in the first embodiment, the flow of water is as shown by the arrows in FIG. The amount of water that can flow between the rotor blades 10 and 11 and the side walls 12e and 12f of the casing 12 is larger than the amount of water that can flow between the pair of rotor blades 10 and 11. For this reason, the water reaching the reservoir portion Z is easily discharged from between the rotary blades 10 and 11 and the side walls 12e and 12f of the casing 12. Therefore, it is possible to prevent the rotation of the rotor blades 10 and 11 from being hindered by water remaining in the pool portion Z.

上記のように構成された実施の形態１の流体エネルギ回収装置によれば、入側開口部から出側開口部へ貫通する流路を有し、流体中に流路を浸漬させて用いるケーシングと、ケーシングの流路内に配置された複数の羽根部を有する回転翼と、回転翼の上部側に設けられ流体エネルギを羽根部で受けることにより得られた回転翼の回転エネルギを回収する回収部と、ケーシングに形成された流路の入側開口部側から回転翼側までに至る縦断面面積が回転翼の羽根部の流体を受ける側に向かって小さくなる流体案内部とを備え、回転翼の流体が流れ込む側とケーシングの側壁との幅方向の間隔より、回転翼の流体が流れ込む側の相反する側とケーシングの側壁との幅方向の間隔が広く形成されており、または、入側開口部から出側開口部へ貫通する流路を有し、流体中に流路を浸漬させて用いるケーシングと、ケーシングの流路内に配置された複数の羽根部を有する一対の回転翼と、一対の回転翼の上部側に設けられ流体エネルギを羽根部で受けることにより得られた回転翼の回転エネルギを回収する回収部と、ケーシングに形成された流路の入側開口部側から一対の回転翼側までに至る縦断面面積が一対の回転翼に向かって小さくなる流体案内部とを備え、各回転翼とケーシングの側壁とのそれぞれの幅方向の間隔は、一対の回転翼間のケーシングの幅方向の半分位置からのそれぞれの幅方向の間隔より広く形成されているので、ケーシング内の流体の溜まりを低減して、流体エネルギ伝達効率が向上する。   According to the fluid energy recovery device of the first embodiment configured as described above, the casing has a flow path that penetrates from the inlet opening to the outlet opening, and is used by immersing the flow path in the fluid. A rotor blade having a plurality of blades disposed in the flow path of the casing, and a recovery unit that is provided on the upper side of the rotor blades and collects rotational energy of the rotor blades obtained by receiving fluid energy at the blades And a fluid guide portion whose longitudinal cross-sectional area from the inlet side opening portion side of the flow path formed in the casing to the rotor blade side becomes smaller toward the fluid receiving side of the blade portion of the rotor blade, The gap in the width direction between the opposite side of the fluid flow of the rotor blade and the side wall of the casing is formed wider than the gap in the width direction between the side into which the fluid flows and the side wall of the casing, or the inlet opening. Penetrating from the outlet to the outlet A casing having a flow path and used by immersing the flow path in a fluid; a pair of rotor blades having a plurality of blade portions arranged in the flow path of the casing; and provided on an upper side of the pair of rotor blades. A recovery section that recovers the rotational energy of the rotor blade obtained by receiving fluid energy at the blade section and a pair of longitudinal sectional areas from the inlet opening side of the flow path formed in the casing to the pair of rotor blade sides are paired. Each of the rotor blades and the side wall of the casing in the width direction has a width between the pair of rotor blades from a half position in the width direction of the casing. Since it is formed wider than the interval in the direction, the accumulation of fluid in the casing is reduced, and the fluid energy transmission efficiency is improved.

実施の形態２．
図５はこの発明の実施の形態２における流体エネルギ回収装置の構成を示す上面図、図６は図５に示した流体エネルギ回収装置の構成を示す斜視図である。図において、上記実施の形態１と同様の部分は同一符号を付して説明を省略する。流体の流れ込む側の相反する側のケーシングの側壁１２ｄは、流体案内部１４が形成されている箇所と対応する箇所に開口部１２０が形成されている。 Embodiment 2. FIG.
FIG. 5 is a top view showing the configuration of the fluid energy recovery apparatus according to Embodiment 2 of the present invention, and FIG. 6 is a perspective view showing the configuration of the fluid energy recovery apparatus shown in FIG. In the figure, the same parts as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. The side wall 12d of the casing on the opposite side of the fluid flow side has an opening 120 at a location corresponding to the location where the fluid guide portion 14 is formed.

上記のように構成された実施の形態２の流体エネルギ回収装置は、ケーシング１２の流路１３が河川などに浸漬される。そして、流体としての水が流路１３を流れる。この際、ケーシング１２の入側開口部１２ａ側では、流体案内部１４と導流体板１５と間に水が流れる。この水は、流体案内部１４が入側開口部１２ａ側から回転翼１１側までに至る縦断面面積が回転翼１１の羽根部３の流体を受ける側に向かって小さくなるテーパ状にて形成されている。そして、回転翼１１の羽根部３がそれぞれ水の流れを受けて回転するこれに伴い、上部板体１および下部板体２は第１および第２の中心点Ｘ、Ｙを中心に回転する。そして、この上部板体１の回転エネルギを回収部４にて回収して、発電等を行う。そして、ケーシング１２の出側開口部１２ｂから水は排出される。   In the fluid energy recovery apparatus of Embodiment 2 configured as described above, the flow path 13 of the casing 12 is immersed in a river or the like. Then, water as a fluid flows through the flow path 13. At this time, water flows between the fluid guide 14 and the fluid guide plate 15 on the inlet side opening 12 a side of the casing 12. The water is formed in a tapered shape in which the fluid guide portion 14 has a longitudinal cross-sectional area from the inlet opening 12a side to the rotor blade 11 side that decreases toward the fluid receiving side of the blade portion 3 of the rotor blade 11. ing. As the blade portion 3 of the rotor blade 11 rotates by receiving the flow of water, the upper plate 1 and the lower plate 2 rotate around the first and second center points X and Y. The rotational energy of the upper plate 1 is recovered by the recovery unit 4 to generate power. And water is discharged | emitted from the exit side opening part 12b of the casing 12. FIG.

このように、ケーシング１２内の水の流れは図５において矢印にて示すように、出側開口部１２ｂから排出されるが、一部の水は回転翼１１の羽根部３の回転によりそのままケーシング１２内を移動して、ケーシング１２の流体案内部１４の流れと反する側の溜まり部分Ｚに至る場合がある。その際、溜まり部分Ｚに水が残存すると、回転翼１１の回転に支障となる。しかしながら、本発明は、回転翼１１の流体が流れ込む側とケーシング１２の側壁１２ｃとの幅方向の間隔Ｈ１より、回転翼１１の流体が流れ込む側の相反する側とケーシング１２の側壁１２ｄとの幅方向の間隔Ｈ２が広く形成されている。よって、回転翼１１の流体の流れ込む側とケーシング１２の側壁１２ｃとの間を流れることができる水の量より、回転翼１１の流体の流れ込む側の相反する側とケーシング１２の側壁１２ｄとの間を流れることができる水の量の方が多い。このため、溜まり部分Ｚに至った水は、回転翼１１の流体の流れ込む側の相反する側とケーシング１２の側壁１２ｄと間から排出されやすい。さらに、本発明は、ケーシング１２の側壁１２ｄに開口部１２０が形成されているため、溜まり部分Ｚに至った水は、この開口部１２０からケーシング１２外に排出される。よって、溜まり部分Ｚに水が残存することはほぼなくなり回転翼１１の回転に支障が生じることをより一層防止することができる。   As described above, the flow of water in the casing 12 is discharged from the outlet opening 12b as indicated by an arrow in FIG. 12 may move to the reservoir portion Z on the side opposite to the flow of the fluid guide portion 14 of the casing 12. At this time, if water remains in the pool portion Z, the rotation of the rotor blade 11 is hindered. However, according to the present invention, the width between the side of the rotor blade 11 into which the fluid flows and the side wall 12d of the casing 12 from the width H1 between the side of the rotor blade 11 into which the fluid flows and the side wall 12c of the casing 12 in the width direction. The direction interval H2 is wide. Therefore, the amount of water that can flow between the fluid flowing side of the rotor blade 11 and the side wall 12c of the casing 12 is larger than the opposite side of the rotor blade 11 on the fluid flowing side and the side wall 12d of the casing 12. There is more water that can flow through. For this reason, the water reaching the reservoir portion Z is likely to be discharged from between the opposite side of the rotor blade 11 where the fluid flows and the side wall 12 d of the casing 12. Furthermore, since the opening 120 is formed in the side wall 12d of the casing 12 according to the present invention, the water reaching the reservoir portion Z is discharged out of the casing 12 through the opening 120. Therefore, water hardly remains in the reservoir portion Z, and it is possible to further prevent the rotation of the rotary blade 11 from being hindered.

また、ここでは１つの回転翼１１を備える例を示したが、これに限られることはなく、例えば図７に示すように、一対の回転翼１０、１１をケーシング１２内に備えた場合においても同様に構成することができる。図７において、上記実施の形態１と同様の部分は同一符号を付して説明を省略する。ケーシング１２の側壁１２ｅ、１２ｆは、流体案内部１４０が形成されている箇所と対応する箇所にそれぞれ開口部１２１、１２２が形成されている。   In addition, although an example in which one rotor blade 11 is provided is shown here, the present invention is not limited to this. For example, as illustrated in FIG. 7, even when a pair of rotor blades 10 and 11 are provided in the casing 12. It can be configured similarly. In FIG. 7, the same parts as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. Openings 121 and 122 are formed in the side walls 12e and 12f of the casing 12 at locations corresponding to locations where the fluid guide portions 140 are formed, respectively.

よって、上記実施の形態２と同様に、水の流れは図７に示す矢印のようになる。そして、一対の回転翼１０、１１間を流れることができる水の量より、各回転翼１０、１１とケーシング１２の側壁１２ｅ、１２ｆとの間を流れることができる水の量の方が多い。このため、溜まり部分Ｚに至った水は、各回転翼１０、１１とケーシング１２の側壁１２ｅ、１２ｆと間から排出されやすい。さらに、本発明は、ケーシング１２の側壁１２ｅ、１２ｄに開口部１２１、１２２が形成されているため、溜まり部分Ｚに至った水は、この開口部１２１、１２１からケーシング１２外に排出される。よって、溜まり部分Ｚに水が残存することはほぼなくなり回転翼１０、１１の回転に支障が生じることをより一層防止することができる。   Therefore, as in the second embodiment, the flow of water is as shown by the arrows in FIG. The amount of water that can flow between the rotor blades 10 and 11 and the side walls 12e and 12f of the casing 12 is larger than the amount of water that can flow between the pair of rotor blades 10 and 11. For this reason, the water reaching the reservoir portion Z is easily discharged from between the rotary blades 10 and 11 and the side walls 12e and 12f of the casing 12. Furthermore, since the opening parts 121 and 122 are formed in the side walls 12e and 12d of the casing 12 according to the present invention, the water reaching the reservoir portion Z is discharged from the casing 12 through the opening parts 121 and 121. Therefore, almost no water remains in the pool portion Z, and it is possible to further prevent the rotation of the rotor blades 10 and 11 from being hindered.

尚、各開口部１２０、１２１、１２２の形状はこれに限られることはなく、他の形状であっても、流体の排出を行うことが可能であれば同様の効果を奏するものであり、ケーシングの強度および流体の流れの強さなどにより、開口部の形状、および大きさなどは適宜設定するものである。   In addition, the shape of each opening part 120, 121, 122 is not restricted to this, Even if it is another shape, if it can discharge | emit the fluid, there will exist the same effect, and a casing The shape and size of the opening are appropriately set depending on the strength of the fluid and the strength of the fluid flow.

上記のように構成された実施の形態２の流体エネルギ回収装置によれば、入側開口部から出側開口部へ貫通する流路を有し、流体中に流路を浸漬させて用いるケーシングと、ケーシングの流路内に配置された複数の羽根部を有する回転翼と、回転翼の上部側に設けられ流体エネルギを羽根部で受けることにより得られた回転翼の回転エネルギを回収する回収部と、ケーシングに形成された流路の入側開口部側から回転翼側までに至る縦断面面積が回転翼の羽根部の流体を受ける側に向かって小さくなる流体案内部とを備え、または、回転翼の流体が流れ込む側とケーシングの側壁との幅方向の間隔より、回転翼の流体が流れ込む側の相反する側とケーシングの側壁との幅方向の間隔が広く形成され、または、流体の流れ込む側の相反する側のケーシングの側壁は、流体案内部が形成されている箇所と対応する箇所に開口部を備え入側開口部から出側開口部へ貫通する流路を有し、流体中に流路を浸漬させて用いるケーシングと、ケーシングの流路内に配置された複数の羽根部を有する一対の回転翼と、一対の回転翼の上部側に設けられ流体エネルギを羽根部で受けることにより得られた回転翼の回転エネルギを回収する回収部と、ケーシングに形成された流路の入側開口部側から一対の回転翼側までに至る縦断面面積が一対の回転翼に向かって小さくなる流体案内部とを備え、各回転翼とケーシングの側壁とのそれぞれの幅方向の間隔は、一対の回転翼間のケーシングの幅方向の半分位置からのそれぞれの幅方向の間隔より広く形成され、ケーシングの側壁は、流体案内部が形成されている箇所と対応する箇所にそれぞれ開口部を備えたので、ケーシング内の流体の溜まりを一層低減して、流体エネルギ伝達効率がより一層向上する。   According to the fluid energy recovery device of the second embodiment configured as described above, the casing has a flow path penetrating from the inlet opening to the outlet opening, and is used by immersing the flow path in the fluid. A rotor blade having a plurality of blades disposed in the flow path of the casing, and a recovery unit that is provided on the upper side of the rotor blades and collects rotational energy of the rotor blades obtained by receiving fluid energy at the blades And a fluid guide part whose longitudinal cross-sectional area from the inlet side opening side of the flow path formed in the casing to the rotor blade side becomes smaller toward the fluid receiving side of the blade part of the rotor blade, or rotating The distance in the width direction between the side where the fluid flows into the rotor blade and the side wall of the casing is wider than the distance between the side where the fluid flows in the blade and the side wall of the casing, or the side where the fluid flows in Of the opposite side The side wall of the housing has a channel that has an opening at a location corresponding to the location where the fluid guiding portion is formed and penetrates from the entrance side opening to the exit side opening, and the channel is immersed in the fluid. A casing to be used, a pair of rotor blades having a plurality of blade portions arranged in the flow path of the casing, and a rotor blade provided on the upper side of the pair of rotor blades and receiving fluid energy at the blade portions. A recovery part for recovering rotational energy, and a fluid guide part in which the longitudinal cross-sectional area from the inlet side opening side of the flow path formed in the casing to the pair of rotor blades decreases toward the pair of rotor blades, The distance between the rotor blades and the side wall of the casing in the width direction is formed wider than the distance between the pair of rotor blades in the width direction of the casing from the half position in the width direction of the casing. Part formed Since with openings each have portions with the corresponding parts, and further reduce the reservoir of the fluid in the casing, a fluid energy transfer efficiency is further improved.

尚、上記実施の形態２においては、ケーシングの側壁に開口部を備え、かつ、回転翼の上記流体が流れ込む側とケーシングの側壁との幅方向の間隔より、回転翼の流体が流れ込む側の相反する側とケーシングの側壁との幅方向の間隔が広く形成されている、または、各回転翼とケーシングの側壁とのそれぞれの幅方向の間隔は、一対の回転翼間のケーシングの幅方向の半分位置からのそれぞれの幅方向の間隔より広く形成されているように、間隔を調整する例を示したがこれに限られることはなく、ケーシングの側壁に開口部のみを備えるようにしても開口部による流体の排出による効果を得ることはできるものである。   In the second embodiment, the side wall of the casing is provided with an opening, and the opposite side of the rotor blade fluid flows from the widthwise interval between the side of the rotor blade where the fluid flows and the side wall of the casing. The width in the width direction between the rotating side and the side wall of the casing is formed wide, or the distance in the width direction between each rotor blade and the side wall of the casing is half of the width direction of the casing between the pair of rotor blades. Although an example of adjusting the interval so as to be formed wider than each interval in the width direction from the position has been shown, the present invention is not limited to this, and the opening may be provided even if only the opening is provided on the side wall of the casing. It is possible to obtain the effect of discharging the fluid.

また、上記各実施の形態においては、主軸を有しない回転翼を用いる例を示したが、これに限られることはなく、主軸を有する回転翼を用いても、導流体板により、流速の速度の減速を低減することができる。よって、流体の流量などに応じて適宜回転翼の形状は選択することが可能である。   In each of the above embodiments, an example using a rotor blade having no main shaft has been described. However, the present invention is not limited to this. Can be reduced. Therefore, the shape of the rotor blade can be selected as appropriate according to the flow rate of the fluid.
