明 細 書 液流発生装置 技術分野  Description Liquid flow generator Technical field
本発明は液流発生装置に関し、液体に波動と流動を同時発生させ、 この波動エネルギーと流動エネルギーの相乗効果により遠くの位 置まで液体を流動させる液流発生装置に関する。 従来技術  The present invention relates to a liquid flow generation device, and more particularly to a liquid flow generation device that simultaneously generates a wave and a flow in a liquid, and flows the liquid to a distant position by a synergistic effect of the wave energy and the flow energy. Conventional technology
従来、 液体に流動を発生させる手段としては、 プロペラ、 スクリ ユー、 夕一ピン等の回転力を利用して流動 （水流） を主体的に発生 させる方法、また噴射流体のエネルギーを外部から液体に与えて流 動 （水流） を起こす方法等がある。 いずれの方法も発生した水流を 遠くの領域まで到達させる事は困難である。その原因はプロペラ等 を高速回転して発生させる水流は瞬間的流速 （加速度） を発生させ ることはできるが、 水の抵抗により直ぐに失速するためであり、 水 を流動、 循環、 瀑気、 攪拌、 混合等を行う装置としてはエネルギー 効率が悪く、 構造が大きく経済的にも問題点があった。 また特殊な 方法として 1 9 4 0年代に開発されたォロイ ド形状の回転体によ る水流発生方法もあるが、複雑な動力伝達により回転させるため構 造上の無理が欠点となり耐久性に乏しく実用性に適さないのが現 状である。  Conventionally, as a means of generating a flow in a liquid, a method of mainly generating a flow (water flow) by using a rotating force of a propeller, a screwdriver, a pin, or the like, or the energy of a jet fluid from the outside to the liquid is used. There is a method of giving a flow (water flow) by giving it. In any case, it is difficult to make the generated water flow reach a distant area. The cause is that the water flow generated by high-speed rotation of propellers etc. can generate instantaneous flow velocity (acceleration), but it stalls immediately due to the resistance of the water, which causes the water to flow, circulate, cascade, and stir. However, the energy efficiency of the equipment for mixing and the like was poor, the structure was large, and there were economical problems. As a special method, there is a water flow generation method using an oroid-shaped rotating body that was developed in the 1940's.However, since it is rotated by complicated power transmission, structural unreasonability is a disadvantage, resulting in poor durability. At present, it is not suitable for practical use.
従って、 大きい湖沼、 池などの水を循環流動させる装置としては 経済的に適応するものがなく実施例は皆無に等しい、また農産物加 ェ、 食品、 各種工場等から出る多量の排水処理装置、 また気体の瀑 気、 異物の攪拌、 混合などは基本的に上記方法により行われている が、水流が遠くまで均一に行き届かない欠点があり効果的な処理が できないのが現状である。これを補うために大きな装置を大きな動 力で運転しているためエネルギー効率が悪いという課題があった。 発明の開示 Therefore, there is no economically applicable device for circulating and flowing water from large lakes, marshes, ponds, etc., and there are no practical examples.Moreover, a large amount of wastewater treatment devices from agricultural products, food, various factories, etc. Gas storms, agitation of foreign matter, mixing, etc. are basically performed by the above method, but at present the water cannot be distributed uniformly even far, and effective treatment cannot be performed at present. To compensate for this, large devices must be There was a problem that energy efficiency was poor due to driving with power. Disclosure of the invention

なお、 後記するように、 翼装置 1 2は比較的小さな駆動力で駆動 可能であり、 したがって、 電動モータ 1 8の電源に太陽電池 （図示 せず） を好適に用いることもできる。  As described later, the wing device 12 can be driven with a relatively small driving force, and therefore, a solar cell (not shown) can be suitably used as a power supply for the electric motor 18.
翼装置 1 2 の第 1 の翼 1 3 と第 2 の翼 1 4とは、図 6に示すよう に正面から見た場合にほぼ十字状をなすように一体的に組み付け られているものであるが、 説明の便宜上、 図 2、 図 3に第 1 の翼 1 3 を、 図 4に第 2の翼 1 4を個別に示した。 第 1 の翼 1 3および第 2の翼 1 4は、互いに反対側となる両面 1 3 a 、 1 3 b , 1 4 a、 1 4 bが外側に対称的に膨出し、 周縁部に いく程厚みを減じる細長い翼をなす。 このような翼は、 細長い椀状 の半体を互いに凹部を対向させて周縁部を溶接等することによつ て構成される。 これら翼の正面形状は図 3に示すように、 その外形 が長楕円状あるいは図 1 に示されるように長円状をなす。また側面 形状は、 図 2に示すように、 その外形が、 2つの扁平な円弧を付き 合わせたような形状をなしている。 角 αは特に限定されないが、 2 0 ° 〜 6 0 ° 位が適当である。 The first wing 13 and the second wing 14 of the wing device 12 are integrally assembled so as to form a substantially cross shape when viewed from the front as shown in FIG. However, for convenience of explanation, FIGS. 2 and 3 show the first wing 13 individually, and FIG. 4 shows the second wing 14 individually. The first wing 13 and the second wing 14 have opposite sides 13 a, 13 b, 14 a, and 14 b that symmetrically bulge outward, and move toward the periphery. It forms elongated wings that reduce the thickness. Such a wing is formed by welding elongated peripheral bowl-shaped halves with their concave portions facing each other, and welding the peripheral edge. The front shape of these wings is an ellipse as shown in Fig. 3 or an ellipse as shown in Fig. 1. Further, as shown in FIG. 2, the side surface shape is such that the outer shape is formed by joining two flat circular arcs. The angle α is not particularly limited, but is suitably about 20 ° to 60 °.
第 1 の翼 1 3は、 図 2に明確なように、 中央部で回転軸 1 5に対 し、 長軸、 短軸共に直角となるように固定される。 一方、 第 2の翼 1 4は、 図 4に示されるように、 中央部で回転軸 1 5に対して、 少 なく とも長軸が斜めに交差するように固定される。この第 2の翼 1 4の長軸の回転軸 1 5に対する交差角 βは、液体からの抵抗をあま り大きなものにしないように、あまり小さな角度にしないのが良い。 例えば交差角 i3は、 6 0 ° 〜 8 0 ° 位が好適である。  The first wing 13 is fixed so that both the major axis and the minor axis are perpendicular to the rotation axis 15 at the center, as is clear from FIG. On the other hand, as shown in FIG. 4, the second wing 14 is fixed so that at least the long axis crosses the rotation axis 15 at the center at least obliquely. The intersection angle β of the long axis of the second wing 14 with the rotation axis 15 should not be too small so as not to make the resistance from the liquid too large. For example, the intersection angle i3 is preferably about 60 ° to 80 °.
上記の例では、翼装置 1 2 を電動モータ 1 8により回転駆動する ようにしたが、 駆動部はこれに限定されるものではない。 例えば、 図 5 に示すように、 回転軸 1 5を中空に形成し、 また第 1 の翼 1 3 および第 2の翼 1 4を回転軸 1 5に連通する中空状に形成し、第 1 の翼 1 3および第 2の翼 1 4の回転後方側となる面に多数の小孔 2 1 を形成し、 高圧流体送出装置 （図示せず） から回転軸 1 5内に 高圧流体を送り込むようにしてもよい。 すなわち、 高圧流体送出装 置から供給される高圧流体が小孔 2 1から噴出される反力により 翼装置 1 2を回転軸 1 5 を中心に回転させるようにするのである。 例えば、 高圧流体送出装置から圧縮空気を、 ホースおよび図示しな いロータリージョイン トを介して中空の回転軸 1 5内に送り込む ようにすることができる。  In the above example, the wing device 12 is rotationally driven by the electric motor 18, but the drive unit is not limited to this. For example, as shown in FIG. 5, the rotating shaft 15 is formed in a hollow shape, and the first wing 13 and the second wing 14 are formed in a hollow shape communicating with the rotating shaft 15. A large number of small holes 21 are formed on the surface on the rotation rear side of the wings 13 and the second wings 14 so that a high-pressure fluid can be fed into the rotary shaft 15 from a high-pressure fluid delivery device (not shown). You may. That is, the wing device 12 is rotated about the rotation axis 15 by the reaction force of the high-pressure fluid supplied from the high-pressure fluid delivery device being ejected from the small holes 21. For example, compressed air can be fed from the high-pressure fluid delivery device into the hollow rotary shaft 15 via a hose and a rotary joint (not shown).
液流発生装置 1 0は上記のように構成されている。 続いて動作について説明する。 The liquid flow generator 10 is configured as described above. Next, the operation will be described.
まず、 波動発生の基本原理を概念図に基ずいて説明する。 図 2 、 図 3に示すように、 第 1の翼 1 3を、 その回転方向前端側および後 端側の淵 1 3 c を鋭角に、かつ中央部分を外方に膨らませ流線形状 に構成し、 回転軸 1 5にほぼ直角に固定しているので、 回転軸 1 5 を水中で矢印方向に回転すると、 第 1の翼 1 3は、 回転前方側では 図 2の X方向に水 （液体） を押し、 一方、 回転後方側では図 2の Y 方向に水が戻る （復元）。 この押出しと復元により、 平面視、 4方 向 （X方向） に波動が発生するのである。  First, the basic principle of wave generation will be described based on a conceptual diagram. As shown in FIGS. 2 and 3, the first wing 13 is formed in a streamlined shape by inflating the edge 13 c at the front end and the rear end in the rotation direction at an acute angle and bulging the center part outward. Since the rotating shaft 15 is rotated in the direction of the arrow underwater because it is fixed at a right angle to the rotating shaft 15, the first wing 13 will rotate in the X direction in Fig. On the other hand, the water returns in the Y direction in Fig. 2 on the rear side of rotation (restoration). By this extrusion and restoration, waves are generated in four directions (X direction) in plan view.
このとき第 1の翼 1 3の翼数と毎分の回転数の積が振動数にな り、 波動の振幅は第 1の翼 1 3の厚みにほぼ依存することになる。 この構成による第 1 の翼 1 3のエネルギー損失は主に翼面の抵 抗損失であるが、 上記のように断面形状を流線形にし、 かつ回転軸 1 5に対し直角に取り付けているので、 抵抗損失は少なく、 少ない 消費電力で、 最大限に効率よく波動を発生しうる。 翼装置 1 2をあ まりに高速で回転すると、 いたずらに水を撹拌することになつて、 波動を遠方に伝達できない。 波動を消失させないためには、 翼の形 状にもよるが、回転数は毎分 5 0 〜 1 5 0回転程度の低速回転にす る必要がある。 これにより消費電力も少なくて済み、 1 0 0 W〜 5 0 0 W程度の低消費電力でも十分に駆動でき、 したがって、 前記し たように太陽電池を電源とすることもできる。  At this time, the product of the number of blades of the first wing 13 and the number of revolutions per minute becomes the frequency, and the amplitude of the wave substantially depends on the thickness of the first wing 13. The energy loss of the first wing 13 due to this configuration is mainly the resistance loss of the wing surface, but since the cross-sectional shape is streamlined as described above and it is mounted at right angles to the rotation axis 15, Low resistance loss, low power consumption and maximum efficient wave generation. If the wing device 12 is rotated at such a high speed, the waves cannot be transmitted to a distant place because the water is agitated unnecessarily. In order to prevent the wave from disappearing, it is necessary to rotate at a low speed of about 50 to 150 revolutions per minute, depending on the shape of the wing. As a result, power consumption can be reduced, and sufficient driving can be performed even with a low power consumption of about 100 W to 500 W, and therefore, a solar cell can be used as a power source as described above.
次に、 第 2の翼 1 4は、 少なく ともその長軸が回転軸 1 5に対し て交差するように回転軸 1 5に斜めに固定されているので、回転軸 1 5が回転することにより、 プロペラと同様に水に流動を与える。 この場合に、 第 2の翼 1 4は、 その両面 1 4 a、 1 4 bが外側に膨 出する形状に形成されているので、回転軸 1 5が矢印方向に回転す ることによって、その回転前方側のふく らみ面のスクリュー流機能 (推進力） によって水が押され、 放射状の水流が発生する。 なお、 第 2の翼 1 4もふく らみをもっていることから、この第 2の翼 1 4 によっても若干水に波動も与える。 Next, the second wing 14 is obliquely fixed to the rotation axis 15 so that at least its major axis intersects the rotation axis 15, so that the rotation axis 15 rotates. Gives fluid to the water, like a propeller. In this case, since the second wing 14 is formed in a shape in which both sides 14a and 14b bulge outward, the rotation of the rotation shaft 15 in the direction of the arrow causes the second wing 14 to rotate. Water is pushed by the screw flow function (propulsion force) of the swollen surface on the front side of rotation, and radial water flow is generated. Since the second wing 14 also has a bulge, this second wing 14 Also gives some water waves.
上記の例では、第 2の翼 1 4をその長軸が回転軸 1 5に対して斜 めに交差するようにしたが、その短軸も回転軸 1 5に対して斜めに 交差するように回転軸 1 5に取り付けることによって、より水流を 発生させやすくなる。 これらの交差角は、 翼のふく らみの程度など に応じて適宜設定するとよい。 また回転軸 1 5の回転速度も、 第 1 の翼 1 3 による波動の発生、第 2の翼 1 4による水流の発生具合に より、 適宜選択するとよい。  In the above example, the second wing 14 has its long axis obliquely crossing the rotation axis 15, but its short axis also crosses the rotation axis 15 obliquely. Attaching to the rotating shaft 15 makes it easier to generate water flow. These intersection angles may be set appropriately according to the degree of swelling of the wings. Further, the rotation speed of the rotation shaft 15 may be appropriately selected depending on how the first wing 13 generates a wave and the second wing 14 generates a water flow.
第 1の翼 1 3 と第 2の翼 1 4とが同時に回転されることにより、 水の動きは、 第 1の翼 1 3による波動と、 第 2の翼 1 4による水流 とが合成された動きとなる。  By rotating the first wing 13 and the second wing 14 at the same time, the movement of water was such that the wave motion of the first wing 13 and the water flow of the second wing 14 were combined. Movement.
図 7に示すように、 液流発生装置 1 0を大きな水槽 （例えば 5 0 mの水泳用プール） 2 5の中央に配置して翼装置 1 2を駆動したと き、 水流に乗りつつ四方に波動が伝わり、 速度は緩いが水槽 2 5— 杯に広がる水流が定常状態で得られた。  As shown in Fig. 7, when the liquid flow generator 10 is placed in the center of a large water tank (for example, a 50-m swimming pool) 25 and the wing device 12 is driven, Waves propagated, and a steady stream of water was obtained at a slow speed, but widening the water tank.
すなわち、第 1の翼 1 3による波動によっては水の流れは生じな いが、 逆にこの波動は遠方にまで伝わる。 そして、 緩い回転速度に より第 2の翼 1 4が回転され、これにより放射状に広がる水流が発 生するが、 回転速度が緩やかなので、 この水流によって上記波動が 破壌されるものではなく、むしろ、水流に波動が乗ることによって、 水流自体遠方にまで伝わるのである。 また、 水流自体緩やかなもの であるので、急激な水流が却って周りの水の抵抗によって急激に減 殺されるのと相違し、定常状態になるまである程度の時間は要する が、やがて水槽 2 5—杯に広がる緩やかな水流が得られたものであ る。 因みに、 水槽 2 5を 5 0 mプールとし、 翼装置 1 2の大きさを 翼の長軸が 5 0 c mのものとし、回転速度を毎分 1 5 0回とした場 合に、 水槽 2 5の隅々にまで届く緩やかな水流と波動が生じた。  In other words, the flow of water does not occur due to the wave caused by the first wing 13, but the wave propagates to a distant place. Then, the second wing 14 is rotated by the slow rotation speed, thereby generating a radially extending water flow.However, since the rotation speed is slow, the wave is not broken by the water flow, but rather is broken. Therefore, the waves flow on the water stream, and the water stream itself travels far away. Also, since the water flow itself is gentle, it takes some time to reach a steady state, unlike the case where the rapid water flow is suddenly attenuated by the resistance of surrounding water. A gentle water current spreading over the area was obtained. By the way, if the water tank 25 is a 50 m pool, the size of the wing device 12 is 50 cm, the long axis of the wing is 50 cm, and the rotation speed is 150 rotations per minute, the water tank 25 Slow water currents and waves reaching every corner of the area.
このよう に、 本発明の液流発生装置 1 0は、 到達距離の大きい波 動と、水に動きを生じさせる水流との相乗現象を究明した結果得ら れたものである。 波動を壌さないために、 また水流のエネルギーが 減殺されないように、翼装置 1 2を緩やかに回転させる必要があり、 そして、 小さな駆動エネルギーにもかかわらず、 水に強い波動ェネ ルギ一と流動エネルギーを同時に与える事を可能にしたともいえ る。 As described above, the liquid flow generation device 10 of the present invention was obtained as a result of investigating a synergistic phenomenon between a wave having a long reach and a water flow that causes the water to move. It was a thing. It is necessary to rotate the wing device 12 gently so as not to dampen the waves and so that the energy of the water stream is not attenuated. It can be said that it has made it possible to give fluid energy at the same time.
また、 図 5 に示すように、 第 1の翼 1 3および第 2の翼 1 4の内 部を中空にし、 回転方向の後方位置に気体、 液体、 または微小固体 を含む高圧流体を噴出する小孔 2 1 を開け、この内部空間部と中空 にした回転軸 1 5 とを連通し、回転軸 1 5を通して高圧流体を第 1 の翼 1 3、 第 2の翼 1 4内に送り込み、 小孔 2 1から噴出させ、 噴 出時の反動力を利用し、 翼装置 1 2を回転させると共に、 爆気、 攪 拌、 混合などを行うようにすることができる。  Also, as shown in FIG. 5, the inside of the first wing 13 and the second wing 14 is made hollow, and a small high pressure fluid containing gas, liquid, or fine solid is ejected to the rear position in the rotation direction. A hole 21 is opened, this internal space is communicated with the hollow rotary shaft 15, and high-pressure fluid is sent through the rotary shaft 15 into the first blade 13 and the second blade 14, and a small hole is formed. The wing device 12 can be rotated using the reaction force generated at the time of jetting, and explosion, stirring, mixing, etc. can be performed.
瀑気を目的としたときの小孔 2 1 の径はなるべく小さく して噴 出空気の表面積を大きくする。噴出された空気は回転している翼 1 3 、 1 4と水流により再撹拌されるため空気粒が非常に微細化され る利点がある。 噴出孔径、 噴出圧力、 回転数などを調節することに より、 パイプの小孔からただ単に空気を噴出する場合に比して、 酸 素溶解効率を 6 0 %以上増大させることができた。 また撹拌、 混合 に於ても従来の方法に比較して数分の 1 の時間により 目的が達せ られた。  The diameter of the small hole 21 for the purpose of a waterfall should be as small as possible to increase the surface area of the jet air. The ejected air is re-mixed by the rotating blades 13 and 14 and the water flow, so that there is an advantage that the air particles are extremely fine. The oxygen dissolution efficiency could be increased by 60% or more compared to the case where air was simply blown out from the small hole of the pipe by adjusting the blowout hole diameter, the blowout pressure, and the rotation speed. In addition, the purpose of stirring and mixing was achieved in a fraction of the time required by the conventional method.
また、 波動と水流との相乗効果により、 緩やかであるが、 広い範 囲に、 かつ遠方にまで水流が達することから、 図 7に示すように、 水槽 2 5の隅々まで水流が行き渡り、コーナー部に異物が堆積する ことがなくなる。 この点、 図 8に示すように、 例えば強力ポンプ 2 6により強力な水流を水槽 2 5内に発生させ、循環させる場合には、 水流が却って減殺され、 隅々にまで水流が行き渡らず、 コーナ一部 に堆積物 2 7が積層する傾向があるが、 本実施例の場合には、 逆に 堆積物が剥離、 除去される傾向が見られた。  In addition, the water flow reaches the corners of the water tank 25, as shown in Fig. 7, because the water flow reaches a wide area and far away due to the synergistic effect of the wave and the water flow. No foreign matter is deposited on the part. In this regard, as shown in Fig. 8, for example, when a strong water flow is generated in the water tank 25 by the high-power pump 26 and circulated, the water flow is rather reduced, and the water flow does not reach every corner. Deposits 27 tend to be partially deposited, but in the case of the present example, conversely, the deposits tended to be peeled off and removed.
本発明の液流発生装置 1 0は、 前記したように、 図 7に示す水槽 2 5を例としたとき水槽 2 5の中央の位置に配置できる。これによ り水流と波動が四方に同時に発生する。 従って、 水槽 2 5の壁面と 短い間隔が確保でき、水流の水速を落とさないで容易に循環流を発 生させることができる。 この点図 8の従来方法では、 液流発生装置 (強力ポンプなど） の構造上、 水槽 2 5の壁面近くに液流発生装置 を配置して、 反対側の壁面に向けて水流を起し循環流を作るため、 壁面との距離が本発明の液流発生装置の約 2倍相当になる。従って 流動水の流速は距離に対し等比級数的に急速に落ちるため、必要な 流速を維持し循環流を継続させるためには、非常に大きなエネルギ 一を必要としていた。 本発明の液流発生装置は、 その水槽内等での 上記配置位置にも関係し、エネルギー効率よく、流動、循環、瀑気、 撹拌、 混合などを可能にした。 As described above, the liquid flow generating device 10 of the present invention has a water tank shown in FIG. When taking 25 as an example, it can be placed at the center of the water tank 25. As a result, water currents and waves are simultaneously generated in all directions. Therefore, a short distance from the wall surface of the water tank 25 can be secured, and the circulating flow can be easily generated without reducing the water speed of the water flow. In the conventional method shown in Fig. 8, in the structure of the liquid flow generator (such as a powerful pump), the liquid flow generator is arranged near the wall of the water tank 25, and the water flow is generated and circulated toward the opposite wall. To create the flow, the distance from the wall is about twice as large as the liquid flow generator of the present invention. Therefore, the flow velocity of the flowing water drops exponentially rapidly with respect to the distance, so that a very large amount of energy was required to maintain the required flow velocity and continue the circulating flow. The liquid flow generator of the present invention is capable of performing flow, circulation, waterfall, agitation, mixing, and the like with high energy efficiency in relation to the above-mentioned arrangement position in a water tank or the like.
