　以下本発明を、図面を参照して説明する。 Hereinafter, the present invention will be described with reference to the drawings.
　図１に示すように、本発明の実施例１の圧力水発電装置１では、前後方向を向く水車筐体２内に、軸受３を介して水平の主軸４を回転可能に支持し、水車筐体２から前方へ突出する主軸４の先端に、ロータ５を装着してある。
　水車筐体２から後方へ突出する主軸４の後端は、発電機７における、図示しない主軸と連結してある。 As shown in FIG. 1, in the pressure water power generator 1 according to the first embodiment of the present invention, a horizontal main shaft 4 is rotatably supported via a bearing 3 in a water turbine housing 2 facing in the front-rear direction. A rotor 5 is attached to the tip of the main shaft 4 protruding forward from the body 2.
The rear end of the main shaft 4 protruding rearward from the water turbine casing 2 is connected to a main shaft (not shown) in the generator 7.
　ロータ５は、主軸４の前端に固定したハブ５Ａの外周に、放射方向を向く複数（３枚～５枚）の揚力型ブレード６を固定して形成されている。
　揚力型ブレード６は正面視において、図２に示すように、翼根部から翼端へかけて、弦長を次第に大とされている。 The rotor 5 is formed by fixing a plurality of (three to five) lift-type blades 6 facing the radial direction on the outer periphery of a hub 5A fixed to the front end of the main shaft 4.
As shown in FIG. 2, the lift type blade 6 has a chord length that gradually increases from the blade root portion to the blade tip, as shown in FIG. 2.
　揚力型ブレード６の最大弦長部６Ａから先端へかけて、次第に円弧状の先尖りとするとともに、最大弦長部６Ａを基点として、その先端部を、噴水管10の方向へ向かって傾斜する傾斜部６Ｂとしてある。 From the maximum chord length portion 6A of the lift-type blade 6 to the tip, the tip gradually becomes an arcuate point, and the tip portion is inclined toward the fountain tube 10 with the maximum chord length portion 6A as a base point. The inclined portion 6B is provided.
　また、図３に示すように、揚力型ブレード６の最大弦長部６Ａの受水面６Ｅは、主軸４の軸心線Ｓに対して、前縁６Ｃよりも後縁６Ｄを、５度～12度ほど正面方向へ傾斜させてある。 Further, as shown in FIG. 3, the water receiving surface 6E of the maximum chord length portion 6A of the lift-type blade 6 has a trailing edge 6D with respect to the axial center line S of the main shaft 4 with a trailing edge 6D of 5 degrees to 12 degrees. It is inclined in the front direction.
　これによって、揚力型ブレード６の受水面６Ｅに高速の噴射水を受けると、揚力型ブレード６は、前縁６Ｃ方向へ回転し、ロータ５が回転すると、発電機７の図示しない主軸が回転して、発電する。 Accordingly, when high-speed jet water is received on the water receiving surface 6E of the lift type blade 6, the lift type blade 6 rotates in the direction of the front edge 6C, and when the rotor 5 rotates, the main shaft (not shown) of the generator 7 rotates. To generate electricity.
　水車筐体２の外周に、環状の配水管８が同心状に配設され、これに導水管９を連結してある。導水管９は、外フランジ９Ａ、９Ａを介して、別の導水管９と連結されており、図５に示す高い位置の小川等の水源水路14から、取水管９Ｂ、９Ｂで取水する。 An annular water distribution pipe 8 is concentrically disposed on the outer periphery of the water turbine casing 2, and a water guide pipe 9 is connected thereto. The water guide pipe 9 is connected to another water guide pipe 9 through outer flanges 9A and 9A, and takes water from the water source water channel 14 such as a creek at a high position shown in FIG. 5 through the water intake pipes 9B and 9B.
　図５において、取水管９Ｂ、９Ｂは、例えば山岳地などで、谷川や小川等の水路14から取水するために使用して、貯水槽13に集水するようになっている。
　貯水槽13は、上部よりも下部の面積を小としたもので、水圧が下部へかかるようになっている。この貯水槽13の下部から導水管９をもって配水管８へ導水するようにしてある。 In FIG. 5, intake pipes 9B and 9B are used to take water from a water channel 14 such as a valley or a stream in a mountainous area, for example, and collect water in a water storage tank 13.
The water storage tank 13 has a lower area than the upper part, and water pressure is applied to the lower part. Water is led from the lower part of the water storage tank 13 to the water distribution pipe 8 through the water guide pipe 9.
　配水管８の正面には、主軸４と平行をなす複数の噴水管10、10を、それぞれの噴射口10Ａが、揚力型ブレード６の傾斜部６Ｂと対面し、かつ揚力型ブレード６の回転方向へ向かって、突設してある。 A plurality of fountain pipes 10, 10 parallel to the main shaft 4 are arranged on the front surface of the water distribution pipe 8. Each jet port 10 </ b> A faces the inclined portion 6 </ b> B of the lift-type blade 6 and the rotational direction of the lift-type blade 6. Projecting toward
　揚力型ブレード６における、最大弦長部６Ａの近域が遠心部にあり、そこは梃子の原理が作用する効果的な作用点であり、その部分に高速の強い噴射水を受けると、総量としての水量が少なくても、ロータ５を、効率良く安定した回転をさせることができる。 In the lift type blade 6, the region near the maximum chord length 6 </ b> A is in the centrifugal portion, which is an effective point of action where the principle of the insulator acts. Even if the amount of water is small, the rotor 5 can be rotated efficiently and stably.
　一般には、揚力型ブレード６の直径以上の径を有する導水管内に、ロータ５を配設し、その導水管一杯の水量をもって、ロータ５を回転させるようになっているが、利用することの出来る水源の水量が少ない場合には、導水管を流れる水量が不十分であったりすると、ロータ５の回転は低速であり、発電をするための十分なトルクを得ることは難しい。 In general, the rotor 5 is disposed in a water conduit having a diameter equal to or larger than the diameter of the lift-type blade 6, and the rotor 5 is rotated with a full amount of water. However, the rotor 5 can be used. When the amount of water in the water source is small, if the amount of water flowing through the water conduit is insufficient, the rotation of the rotor 5 is slow, and it is difficult to obtain sufficient torque for power generation.
　しかし、本発明においては、図１に示すように、導水管９の直径は、ロータ５の直径と対比して遙かに小さいものとしてあり、噴射口10Ａの直径は、更に小さいから、落差に伴って、噴射口10Ａから噴射する噴射水は高速となり、かつ高圧のものとなる。 However, in the present invention, as shown in FIG. 1, the diameter of the water conduit 9 is much smaller than the diameter of the rotor 5, and the diameter of the injection port 10A is further smaller. Accordingly, the jet water jetted from the jet port 10A becomes high speed and high pressure.
　その噴射口10Ａは、揚力型ブレード６の受水面６Ｅにおける、最大弦長部６Ａに対面しているので、噴射水は、最大弦長部６Ａに適切に当り、揚力型ブレード６を、前縁６Ｃ方向へ向かって効果的に回転させる。 Since the jet port 10A faces the maximum chord length portion 6A on the water receiving surface 6E of the lift type blade 6, the jet water appropriately hits the maximum chord length portion 6A, and the lift type blade 6 is brought into contact with the leading edge. Rotate effectively toward 6C.
　すなわち、水流は、揚力型ブレード６の受水面６Ｅ全域に当っても、翼端方向へ移動するものであり、翼端部位に直接当てる方が、梃子の作用によって、強い回転力が得られる。 That is, the water flow moves toward the blade tip even if it hits the entire area of the water receiving surface 6E of the lift-type blade 6, and a strong rotational force can be obtained by direct application to the blade tip portion due to the action of the insulator.
　噴射口10Ａから噴射される水の量は、導水管９の断面積を噴射口10Ａの断面積で徐して、導水管９における流速を乗じた数値を、噴射口10Ａの数で除した数値に比例する。 The amount of water injected from the injection port 10A is a value obtained by dividing the numerical value obtained by multiplying the cross-sectional area of the water conduit 9 by the cross-sectional area of the injection port 10A and the flow velocity in the water conduit 9 by the number of the injection ports 10A. Is proportional to
　例えば、導水管９の直径が20ｃｍで、その断面積を314ｃｍ２、噴射口10Ａの直径が４ｃｍで、その断面積を12.56ｃｍ２、導水管９の流速を２m/sとすると、25×２＝50。噴射口５個のうちの１個は10m/sの高速流となる。噴射口10Ａの直径を２倍の８ｃｍとした場合には、流速は５m/sと半減する。 For example, if the diameter of the water conduit 9 is 20 cm, its cross-sectional area is 314 cm 2 , the diameter of the injection port 10A is 4 cm, its cross-sectional area is 12.56 cm 2 , and the flow velocity of the water conduit 9 is 2 m / s, 25 × 2 = 50. One of the five injection ports has a high-speed flow of 10 m / s. When the diameter of the injection port 10A is doubled to 8 cm, the flow velocity is halved to 5 m / s.
　図１において、導水管９の導入口（図１の右端）を高い位置へ向かって傾斜させるか、或いは直立させると、導水管９内の流水は、重力が加えられて、噴射口10Ａに大きな水圧がかかり、より高速流となって噴射される。 In FIG. 1, when the introduction port (right end in FIG. 1) of the water conduit 9 is inclined toward a high position or is made to stand upright, the flowing water in the water conduit 9 is subjected to gravity and becomes large at the injection port 10A. Water pressure is applied and jetted as a faster flow.
　従って、利用する流水の量が少なくても、導水管９の先端部に配水管８を連結し、これに、直径の小さな噴射口10Ａを有する噴水管10を設けることによって、導水管９を流れる流水の速度よりも高速、かつ高圧な噴水を、噴射口10Ａから噴射し、これを揚力型ブレード６の、最大弦長部６Ａの部分に当てることにより、少ない流水によって、効率よくロータ５を回転させることができる。 Therefore, even if the amount of flowing water to be used is small, the water distribution pipe 8 is connected to the tip of the water conduit 9, and the fountain pipe 10 having the injection port 10 </ b> A having a small diameter is provided to the water distribution pipe 8. High-speed and high-pressure fountain is injected from the injection port 10A and applied to the maximum chord length 6A portion of the lift-type blade 6 to efficiently rotate the rotor 5 with less flowing water. Can be made.
　導水管９の直径は、利用することが出来る用水の量によって定め、噴射口10Ａの直径は、利用出来る水量、傾斜、流速、噴射口10Ａの数等から、適宜定める。噴射口10Ａの形状は円形に限定されず、楕円形、長方形、三角形などの任意の形状とされる。 The diameter of the water conduit 9 is determined by the amount of water that can be used, and the diameter of the injection port 10A is determined as appropriate from the amount of water that can be used, the inclination, the flow velocity, the number of the injection ports 10A, and the like. The shape of the injection port 10A is not limited to a circle, and may be any shape such as an ellipse, a rectangle, or a triangle.
　図示するロータ５は、風車としても回転効率が優れていることが知られているが、噴射水は、風より質量が高く、速度が一定で、間断なく当てることによって、少水量でも、安定した効率の良い発電をさせることができる。 The rotor 5 shown in the figure is known to have excellent rotational efficiency as a windmill, but the jet water has a higher mass than the wind, the speed is constant, and it is stable even with a small amount of water when applied without interruption. Efficient power generation can be achieved.
　図４は、圧力水発電装置の実施例２の要部を示す横断平面図である。前例と同じ部材には、同じ符号を付して説明を省略する。この実施例２では、噴水管10内に空気を引込み、気泡混合水を噴射口10Ａから噴射させるようになっている。 FIG. 4 is a cross-sectional plan view showing the main part of the second embodiment of the pressure water power generation apparatus. The same members as those of the previous example are denoted by the same reference numerals and description thereof is omitted. In the second embodiment, air is drawn into the fountain pipe 10 and the bubble mixed water is jetted from the jet port 10A.
　図４において、配水管８の外周面に突設した噴水管10の中部に、アスピレータ11（aspirator＝吸気器）を内装し、通路11Ａ内に吸気道11Ｂの吸出口11Ｃを設け、これと連通する吸気口11Ｄを、噴水管10の外に表出して、これに導気管12を装着してある。 In FIG. 4, an aspirator 11 (aspirator) is provided in the middle of a fountain pipe 10 projecting from the outer peripheral surface of a water distribution pipe 8, and an intake port 11C of an intake passage 11B is provided in a passage 11A. The intake port 11D to be exposed is exposed outside the fountain pipe 10, and the air guide pipe 12 is attached thereto.
　流水が配水管８から通路11Ａ内を、高速で通過すると、吸出口11Ｃ付近の空気がこれに引かれて、吸気道11Ｂ内が負圧となり、外から導気管12内に、空気がベンチュリー効果によって引込まれる。通路11Ａ内に入った空気は、気泡状となって水と混合されて、噴射口10Ａから噴射される。 When the flowing water passes through the distribution pipe 8 through the passage 11A at a high speed, the air in the vicinity of the suction port 11C is drawn by this, and the inside of the intake passage 11B becomes negative pressure. Drawn by. The air that has entered the passage 11A is bubbled and mixed with water, and is ejected from the ejection port 10A.
　図４において、アスピレータ11と吸出口11Ｃの間の水溜部10Ｂに、流水が一時的に溜ることになる。一方、配水管８から通路11Ａ内に押出された流水は、吸出口11Ｃから空気を引込むことによって嵩が増大し、水溜部10Ｂに入り、水溜部10Ｂにおける水嵩を増大させて速度を高める。その結果、噴射口10Ａからは、高速流が噴射されて、ロータ５が効率よく回転される。 In FIG. 4, running water temporarily accumulates in the water reservoir 10B between the aspirator 11 and the suction port 11C. On the other hand, the flowing water extruded from the water distribution pipe 8 into the passage 11A increases in volume by drawing air from the suction port 11C, enters the water reservoir 10B, increases the water volume in the water reservoir 10B, and increases the speed. As a result, a high-speed flow is injected from the injection port 10A, and the rotor 5 is rotated efficiently.
　図６は圧水力発電装置の実施例３の平面図である。前例と同じ部材には、同じ符号を付して説明を省略する。
　この実施例３においては、導水管９から配水管８へバイパス９Ｃを設け、バイパス９Ｃに加圧ポンプ15を設け、導水管９に近接して逆止弁16を設けている。 FIG. 6 is a plan view of Embodiment 3 of the hydraulic power generator. The same members as those of the previous example are denoted by the same reference numerals and description thereof is omitted.
In the third embodiment, a bypass 9C is provided from the water conduit 9 to the water distribution pipe 8, a pressure pump 15 is provided in the bypass 9C, and a check valve 16 is provided in the vicinity of the water conduit 9.
　また、ブレード５の下部に受水槽17を設け、受水槽17から加圧ポンプ15より導水管９に近接して、バイパス９Ｃを配水管８に接続してあり、バイパス９Ｃに近接して逆止弁16を設けてある。 In addition, a water receiving tank 17 is provided at the lower part of the blade 5, and the bypass 9C is connected to the water distribution pipe 8 from the water receiving tank 17 by the pressurizing pump 15 and is connected to the water distribution pipe 8. A valve 16 is provided.
　これは、ブレード６を回転させた水を、受水槽17に受けて再利用するもので、加圧ポンプ15によって吸い上げられ、加圧されて、配水管８に供給される。また、渇水期において、導水管９に流れる水量が少なくなった時に、バイパス９Ｃの回路に水を流して、加圧ポンプ15で加圧して配水管８へ給水するようにする。 This is the water that has rotated the blade 6 is received in the water receiving tank 17 and reused, sucked up by the pressurizing pump 15, pressurized and supplied to the water distribution pipe 8. Further, in the drought period, when the amount of water flowing through the water conduit 9 decreases, water is supplied to the circuit of the bypass 9 </ b> C, pressurized by the pressurizing pump 15, and supplied to the water distribution pipe 8.
　ブレード６は、先端の傾斜部６Ｂを備えない物も使用される。配水管10に付設される噴水管10は、１本でもよく、本数には限定されない。１本の場合は、ブレード６の回転方向へ噴射口10Ａを向けて、抗力型のように使用しても、揚力型ブレードは効率良く回転する。 The blade 6 may be one that does not have the tip inclined portion 6B. The number of fountain pipes 10 attached to the water distribution pipe 10 may be one, and is not limited to the number. In the case of one, even if the injection port 10A is directed in the rotation direction of the blade 6 and used like a drag type, the lift type blade rotates efficiently.
　図７は、本発明の圧力水発電装置の実施例４を示す一部横断面を示す平面図で、図８は正面図である。前例と同じ部材には、同じ符号を付して説明を省略する。この実施例４は、噴水管10を環状に突出させて、その先端に、噴射口10Ａを多数、環状に、かつ点線状に連続して形成したものである。 FIG. 7 is a plan view showing a partial cross section showing Example 4 of the pressure water power generator of the present invention, and FIG. 8 is a front view. The same members as those of the previous example are denoted by the same reference numerals and description thereof is omitted. In the fourth embodiment, the fountain tube 10 is protruded in an annular shape, and a large number of injection ports 10A are continuously formed in the annular shape and dotted line at the tip thereof.
　噴射口10Ａは、一定の間隔置きに点線状に連続しているので、ここから噴射される噴射水は、ほぼ環状に噴射され、ブレード６が回転していても、かつブレード６の弦長が短いものであっても、間断なくブレードの受水面に当たるので、例え水量が少なくても、噴射速度が高速なので、ブレード６を効率良く回転させて、効率良く発電させることができる。 Since the injection port 10A is continuous in the form of a dotted line at regular intervals, the water injected from here is injected in a substantially annular shape, and even if the blade 6 is rotating, the chord length of the blade 6 is Even if it is short, it hits the water receiving surface of the blade without interruption, so even if the amount of water is small, the injection speed is high, so that the blade 6 can be rotated efficiently to generate power efficiently.
　なお、噴射口10Ａの連続は、点線状の噴射口10Ａを接続して環状の切線状とすることもできる。また、点線状の噴射口10Ａは、噴水管10を省いて、配水管８に直接形成することができる。 It should be noted that the continuation of the injection ports 10A can be formed into a circular cut line by connecting the dotted injection ports 10A. The dotted injection port 10A can be directly formed in the water distribution pipe 8 without the fountain pipe 10.
　本発明の圧力水発電装置は、少水量でも、ロータを効率良く回転させることが出来るので、澤、小川等の水量の少ない地域において、効率良く安定した発電をする水力発電機として利用することができる。また高層ビル等の排水を利用することもできる。 Since the rotor of the present invention can efficiently rotate the rotor even with a small amount of water, it can be used as a hydroelectric generator for efficient and stable power generation in areas with low water volume such as Sawa and Ogawa. it can. It is also possible to use drainage from high-rise buildings.
