　補発電機１６は、鉛直方向において上部タンク１１及び中部タンク１２よりも下方に位置するとともに、下部タンク１３よりも上方に位置し、流路Ｂ，Ｂ２を介して上部タンク１１の下流側に、かつ、流路Ｂ（の一部）、流路Ｃ、流路Ｂ２を介して中部タンク１２の下流側に設けられている。また、補発電機１６には流路Ｅが接続している。 The auxiliary generator 16 is positioned below the upper tank 11 and the middle tank 12 in the vertical direction, is positioned above the lower tank 13, and is downstream of the upper tank 11 via the flow paths B and B2. Further, it is provided on the downstream side of the middle tank 12 via (part of) the flow path B, the flow path C, and the flow path B2. A flow path E is connected to the auxiliary generator 16 .
　また、流路Ｂ１における主発電機１５の上流側には遮断弁ＦＣ４が、さらにその上流側には流量計ＦＴ７が、流路Ｂ２における補発電機１６の上流側には遮断弁ＦＣ５が、さらにその上流側には流量計ＦＴ８が、それぞれ設けられている。 In addition, a shutoff valve FC4 is upstream of the main generator 15 in the flow path B1, a flow meter FT7 is further upstream thereof, and a shutoff valve FC5 is further upstream of the auxiliary generator 16 in the flow path B2. A flow meter FT8 is provided on the upstream side thereof.
補発電機１６は、自身よりも鉛直方向上方に位置する上部タンク１１から流入する水により水車が回転することで発電し、発電に用いた水は流路Ｅに排出される。ただし、主発電機１５同様、閉仕切弁Ｃ１を開状態とすることで、自身よりも鉛直方向上方に位置する中部タンク１２から流入する水も用いることも可能である（補発電機１６が上部タンク１１から流入する水を用いて発電するか、中部タンク１２から流入する水を用いて発電するかを、弁ＶＡ１，Ｃ１により切り替えられる）。なお、流路Ｅは流路Ｄに合流している。 The auxiliary power generator 16 generates power by rotating the water wheel with water flowing in from the upper tank 11 located vertically above itself, and the water used for power generation is discharged to the flow path E. However, similarly to the main generator 15, by opening the closing gate valve C1, it is also possible to use the water flowing in from the central tank 12 located vertically above itself (the auxiliary generator 16 It is switched by the valves VA1 and C1 whether to generate power using the water flowing from the tank 11 or using the water flowing from the middle tank 12). In addition, the flow path E merges with the flow path D.
　下部タンク１３は、流路Ｄ，Ｅを介して主発電機１５及び補発電機１６に連通しているため、（純水器１４から流入する水とともに）主発電機１５及び補発電機１６から流入する水を溜めることができる。また、下部タンク１３には流路Ｆが接続している。 Since the lower tank 13 communicates with the main generator 15 and the auxiliary generator 16 via the flow paths D and E, It can collect incoming water. A flow path F is connected to the lower tank 13 .
中部タンク１２は、流路Ｆ及び後述の流路Ｊを介して下部タンク１３の下流側に設けられている。また、中部タンク１２には流路Ｇが接続しており、上部タンク１１は、流路Ｇ、後述の流路Ｌ、及び、後述の流路Ｉ（の一部）を介して中部タンク１２の下流側に、かつ、後述の流路Ｉを介して下部タンク１３の下流側に設けられている。 The middle tank 12 is provided downstream of the lower tank 13 via a flow path F and a flow path J, which will be described later. Further, the middle tank 12 is connected to the flow path G, and the upper tank 11 is connected to the middle tank 12 via the flow path G, the flow path L described later, and (a part of) the flow path I described later. It is provided on the downstream side and on the downstream side of the lower tank 13 via a flow path I, which will be described later.
第１フルイダインポンプ１７は流路Ｆに設けられており、下部タンク１３の水を中部タンク１２に揚水する。第２フルイダインポンプ１８は流路Ｇに設けられており、中部タンク１２の水を上部タンク１１に揚水する。 A first fluid-in pump 17 is provided in the flow path F and pumps the water in the lower tank 13 to the middle tank 12 . A second fluid-in pump 18 is provided in the flow path G and pumps the water in the middle tank 12 to the upper tank 11 .
ここで、フルイダインポンプについて簡単に説明する。なお、以下では第１フルイダインポンプ１７を例に挙げて説明しているが、第２フルイダインポンプ１８も同様の構成である。 Here, the fluidyne pump will be briefly described. Although the first fluidyne pump 17 is described below as an example, the second fluidyne pump 18 has the same configuration.
第１フルイダインポンプ１７は、鉛直方向下方において流路Ｆに連通するＵ字状の第１管片１７Ａ、管片１７Ａの両上端部を、勾配を付けて連通する直線状の第２管片１７Ｂ、第１管片１７Ａの両上端部にそれぞれ設けられる高熱部１７Ｃ及び冷却部１７Ｄを備えている。また、第２管片１７Ｂ内は気相部となり、熱再生機（圧力損失が少なく、熱容量をもったもの）１７ＢＡ、及び、熱再生機１７ＢＡよりも冷却部１７Ｄ側に設けられた遮断弁１７ＢＢが備えられている。遮断弁１７ＢＢは、第２管片１７Ｂ内における高熱部１７Ｃ側の気相部温度が所定の温度に達したときに開状態となるものとする。なお、第１管片１７Ａ内には流路Ｆ内の水が入り込んでいる。 The first fluidyne pump 17 has a U-shaped first pipe piece 17A that communicates with the flow path F in the vertical direction downward, and a linear second pipe piece that connects both upper ends of the pipe piece 17A with a slope. 17B, a high heat portion 17C and a cooling portion 17D provided at both upper end portions of the first pipe piece 17A. In addition, the inside of the second tube piece 17B becomes a gas phase portion, a heat regenerator (having a small pressure loss and a large heat capacity) 17BA, and a cutoff valve 17BB provided closer to the cooling part 17D than the heat regenerator 17BA. is provided. The cutoff valve 17BB is opened when the temperature of the gas phase on the side of the high heat portion 17C in the second pipe piece 17B reaches a predetermined temperature. In addition, the water in the flow path F has entered into the first pipe piece 17A.
高熱部１７Ｃ（熱を気相部に伝える部分）に高熱量を供給できれば仮に遮断弁１７ＢＢが無くても自然とフルイダインの振動現象が発生する。しかし、例えば太陽光を熱源とする場合、入熱量は朝日からはじまり、徐々に増加する。そのような状況では、第２管片１７Ｂ内の気相部全体が均一に温まるだけで振動現象は生じにくい。遮断弁１７ＢＢを設け、これを閉状態とすることで、第２管片１７Ｂのうち遮断弁１７ＢＢより高熱部１７Ｃ側だけが体積が増加し、結果として第１管片１７Ａ内の水面に差が生じる。水面に差が生じた段階で遮断弁１７ＢＢを開状態とすることで振動現象のきっかけを与えることができる。 If a high amount of heat can be supplied to the high heat portion 17C (the portion that transfers heat to the gas phase portion), the fluidyne vibration phenomenon will naturally occur even if the cutoff valve 17BB is not provided. However, for example, when sunlight is used as a heat source, the amount of heat input starts from the morning sun and gradually increases. In such a situation, the entire gas phase portion inside the second tube piece 17B is only uniformly warmed, and the vibration phenomenon is unlikely to occur. By providing the shut-off valve 17BB and closing it, only the high-temperature portion 17C side of the second pipe piece 17B increases in volume from the shut-off valve 17BB, and as a result, the water surface in the first pipe piece 17A differs. occur. By opening the shut-off valve 17BB at the stage when a difference in water surface occurs, the vibration phenomenon can be triggered.
このようにして構成された第１フルイダインポンプ１７は、まず、第１管片１７Ａ内において、高熱部１７Ｃ側端部の水位が押し下げられ、冷却部１７Ｄ側端部の水位が押し上げられているとする。次に、冷却部１７Ｄ側端部の水位は重力によって下がり始め、同時に高熱部１７Ｃ側端部の水位は上がり始める。さらに、第２管片１７Ｂ内の気相部では高熱部１７Ｃ側の気体が冷却部１７Ｄ側へ流れ始める。 In the first fluidyne pump 17 constructed in this manner, the water level at the end on the high heat section 17C side is pushed down and the water level at the end on the cooling section 17D side is pushed up in the first pipe piece 17A. and Next, the water level at the end on the cooling section 17D side begins to fall due to gravity, and at the same time the water level at the end on the high heat section 17C side begins to rise. Furthermore, in the gas phase portion inside the second pipe piece 17B, the gas on the side of the high temperature portion 17C starts to flow toward the side of the cooling portion 17D.
このとき、高熱部１７Ｃ側にて保有していた熱は熱再生機１７ＢＡにて奪われ、冷たくなった気体が冷却部１７Ｄ側へ流れる。冷却部１７Ｄ側ではクーラ（図示略）によってさらに気体温度が下がる。 At this time, the heat retained in the high heat section 17C side is taken away by the heat regenerator 17BA, and the cooled gas flows to the cooling section 17D side. On the cooling part 17D side, the gas temperature is further lowered by a cooler (not shown).
これにより、気相側全体の体積が低下する。それに伴って気相部の圧力低下が発生し、その力によって第１管片１７Ａ内の液相部が配管Ｆ（後述するフルイダインポンプ用逆止弁１７Ｆの上流側）の水を吸引する。 This reduces the volume of the entire gas phase side. As a result, a pressure drop occurs in the gas phase, and the pressure causes the liquid phase in the first pipe piece 17A to suck water from the pipe F (on the upstream side of the fluidine pump check valve 17F, which will be described later).
高熱部１７Ｃ側の水位が冷却部１７Ｄ側の水位よりも上がることで、再び高熱部１７Ｃ側の水位が下がり始める。同時に、冷却部１７Ｄ側の水位は上がり始める。 When the water level on the high heat section 17C side rises above the water level on the cooling section 17D side, the water level on the high heat section 17C side begins to fall again. At the same time, the water level on the cooling section 17D side begins to rise.
気相部では冷却部１７Ｄ側から高熱部１７Ｃ側へ気体が移動する。熱再生機１７ＢＡを通過することで、先ほど奪われた熱を回収して高熱部１７Ｃ側へ流れる。高熱部１７Ｃ側では高熱部１７Ｃによってさらに気体の温度が上昇する。これによって、気相部全体の圧力が上昇し、第１管片１７Ａは流路Ｆから吸引した配管Ｆ（後述するフルイダインポンプ用逆止弁１７Ｅの下流側）に水を押し出そうとする。 In the gas phase portion, the gas moves from the cooling portion 17D side to the high temperature portion 17C side. By passing through the heat regenerator 17BA, the heat deprived earlier is recovered and flows to the high heat section 17C side. On the side of the high heat section 17C, the temperature of the gas further rises due to the high heat section 17C. As a result, the pressure of the entire gas phase portion rises, and the first pipe piece 17A tries to push out water from the flow path F into the pipe F (downstream of a fluidyne pump check valve 17E, which will be described later). .
上述の繰り返しによって第１管片１７Ａが水の吸引と吐出を繰り返す力がポンプとして作用し、流路Ｆにおける、第１フルイダインポンプ１７との接続箇所の前後に、同方向の２つのフルイダインポンプ用逆止弁１７Ｅ，１７Ｆを設けることで、ダイヤフラムポンプのようにして流体を流すことができる。
以上がフルイダインポンプについての簡単な説明である。 By repeating the above, the force of the first pipe piece 17A repeatedly sucking and discharging water acts as a pump. By providing the pump check valves 17E and 17F, the fluid can flow like a diaphragm pump.
The above is a brief description of the fluidyne pump.
また、流路Ｆは、第１フルイダインポンプ１７との接続箇所よりも下流側に流量調整弁ＦＯ１が、流量調整弁ＦＯ１の下流側に流量計ＦＴ２が、流量計ＦＴ２の下流側に三方弁Ｔ１が設けられており、流路Ｇは、第２フルイダインポンプ１８との接続箇所よりも下流側に流量調整弁ＦＯ２が、流量調整弁ＦＯ２の下流側に流量計ＦＴ３が、流量計ＦＴ３の下流側に三方弁Ｔ２が設けられている。 In addition, the flow path F has a flow control valve FO1 downstream of the connection with the first fluidyne pump 17, a flow meter FT2 downstream of the flow control valve FO1, and a three-way valve downstream of the flow meter FT2. T1 is provided, and in the flow path G, the flow control valve FO2 is downstream of the connection point with the second fluidyne pump 18, the flow meter FT3 is downstream of the flow control valve FO2, and the flow meter FT3 is connected. A three-way valve T2 is provided downstream.
ちなみに、フルイダインポンプ１７，１８は、熱を与えることで内部エネルギーの増加と仕事を行うものである。すなわち、入熱＝内部エネルギー上昇＋仕事＋排熱＋損失となる。そして、第１管片１７Ａ内の水の振動の振幅が大きいほど内部エネルギーが大きい状態となる。内部エネルギーが大きい状態の方が高熱部１７Ｃ付近の流動状態が向上（ヌッセルト数が向上）し、フルイダインへの入熱量が向上する。 Incidentally, the fluidyne pumps 17 and 18 increase internal energy and work by applying heat. That is, heat input=increase in internal energy+work+exhaust heat+loss. The larger the vibration amplitude of the water in the first pipe piece 17A, the larger the internal energy. When the internal energy is large, the flow state near the high heat portion 17C is improved (the Nusselt number is improved), and the amount of heat input to the fluidyne is improved.
したがって、内部エネルギーをある程度高めてから仕事をさせる方が効率的であり、そのために内部エネルギーが十分高まるまで流量調整弁ＦＯ１の開度を小さくしておくことが望ましい。一方、内部エネルギーが高くなりすぎるとフルイダイン内部の圧力損失が高くなりすぎ、逆に非効率となるので、流量調整弁ＦＯ１の開度を大きく開けて内部エネルギーを低下させる。このようにフルイダインの内部エネルギーを適切な状態に保ちながら、流量調整弁ＦＯ１の開度を適時調整することで効率的に揚水の仕事をさせることができる。 Therefore, it is more efficient to increase the internal energy to some extent before doing work, and for this reason, it is desirable to keep the opening of the flow control valve FO1 small until the internal energy is sufficiently increased. On the other hand, if the internal energy becomes too high, the pressure loss inside the fluidyne will become too high, and conversely, it will become inefficient. By adjusting the opening degree of the flow control valve FO1 appropriately while maintaining the internal energy of the Fluidyne in this way, the work of pumping water can be performed efficiently.
そして、流路Ｆは、三方弁Ｔ１により流路Ｊの一端、及び、流路Ｋの一端と接続している。流路Ｊの他端は中部タンク１２に接続しており、流路Ｋの他端は後述の排水管ＤＲと合流している。さらに、流路Ｇは、三方弁Ｔ１により流路Ｌの一端、及び、流路Ｍの一端と接続している。流路Ｌの他端は後述の流路Ｉに合流しており、流路Ｍの他端は流路Ｋと合流している。なお、流路Ｋ、流路Ｍには、それぞれ逆止弁ＣＨ１，ＣＨ２が設けられている。 The channel F is connected to one end of the channel J and one end of the channel K by a three-way valve T1. The other end of the flow path J is connected to the central tank 12, and the other end of the flow path K merges with a drain pipe DR, which will be described later. Further, the channel G is connected to one end of the channel L and one end of the channel M by a three-way valve T1. The other end of the flow path L joins the flow path I described later, and the other end of the flow path M joins the flow path K. The flow paths K and M are provided with check valves CH1 and CH2, respectively.
　上部タンク１１、中部タンク１２、下部タンク１３の各側面には、それぞれ水位計ＬＳ１，ＬＳ２，ＬＳ３が設けられている。揚水運転が働いている間、第１フルイダインポンプ１７及び第２フルイダインポンプ１８はそれらへの入熱に従って常に揚水を続ける。その際、各タンク１１，１２への揚水と各タンク１１，１２からの排水がバランスするように、適切に主発電機１５又は補発電機１６を切り替える必要がある。 Water level gauges LS1, LS2, and LS3 are provided on each side of the upper tank 11, middle tank 12, and lower tank 13, respectively. While the pumping operation is working, the first fluidy-in pump 17 and the second fluidy-in pump 18 always keep pumping according to the heat input to them. At that time, it is necessary to appropriately switch the main generator 15 or the auxiliary generator 16 so that the water pumped into the tanks 11 and 12 and the water discharged from the tanks 11 and 12 are balanced.
下部タンク１３の水位が減少すると、主発電機１５及び補発電機１６の双方が発電を開始する。第１フルイダインポンプ１７及び第２フルイダインポンプ１８による揚水量が低下する又は揚水しなくなると、主発電機１５への流路Ｂ１上に設けられた遮断弁ＦＣ４を閉じるか、又は、補発電機１６への流路Ｂ２上に設けられた遮断弁ＦＣ５を閉じる。 When the water level in the lower tank 13 decreases, both the main generator 15 and the auxiliary generator 16 start generating electricity. When the amount of water pumped by the first fluidy-in pump 17 and the second fluidy-in pump 18 decreases or ceases to be pumped, the shutoff valve FC4 provided on the flow path B1 to the main generator 15 is closed, or the auxiliary power generator The shutoff valve FC5 provided on the flow path B2 to the machine 16 is closed.
その際、揚水量は流量計ＦＴ２，ＦＴ３で、落水量は流量計ＦＴ７，ＦＴ８で、それぞれ監視される。主発電機１５及び補発電機１６を設ける理由としては、それぞれの発電機には発電効率の特性があり、落水量が小量の場合は大型の主発電機１５に僅かに水を流すよりも、小流量用の補発電機１６にて発電させた方が、効率が良いためである。 At that time, the amount of pumped water is monitored by flowmeters FT2 and FT3, and the amount of falling water is monitored by flowmeters FT7 and FT8, respectively. The reason why the main generator 15 and the auxiliary generator 16 are provided is that each generator has a characteristic of power generation efficiency, and when the amount of falling water is small, it is preferable to allow a small amount of water to flow through the large main generator 15. This is because it is more efficient to generate power with the auxiliary generator 16 for small flow rates.
　また、上部タンク１１、中部タンク１２、下部タンク１３の各天井には、それぞれ空気圧計ＰＴ１，ＰＴ２，ＰＴ３が設けられている。 Air pressure gauges PT1, PT2, and PT3 are provided on the ceilings of the upper tank 11, middle tank 12, and lower tank 13, respectively.
　さらに、上部タンク１１、中部タンク１２、下部タンク１３の各側面には、それぞれ水温計ＴＴ１，ＴＴ２，ＴＴ３が設けられている。上部タンク用ヒータ２１は、水温計ＴＴ１の計測に基づき、上部タンク１１の水温が第１所定温度を下回ると起動し、第２所定温度を上回ると停止する。また、中部タンク用ヒータ２２は、水温計ＴＴ２の計測に基づき、中部タンク１２の水温が第１所定温度を下回ると起動し、第２所定温度を上回ると停止する。そして、下部タンク用ヒータ２３は、水温計ＴＴ３の計測に基づき、下部タンク１３の水温が第１所定温度を下回ると起動し、第２所定温度を上回ると停止する。 Furthermore, water temperature gauges TT1, TT2, and TT3 are provided on each side of the upper tank 11, middle tank 12, and lower tank 13, respectively. The upper tank heater 21 starts when the water temperature in the upper tank 11 falls below a first predetermined temperature and stops when it exceeds a second predetermined temperature based on the measurement of the water temperature gauge TT1. Further, the middle tank heater 22 is activated when the water temperature of the middle tank 12 falls below the first predetermined temperature and stops when the water temperature exceeds the second predetermined temperature based on the measurement of the water temperature gauge TT2. The lower tank heater 23 is activated when the water temperature in the lower tank 13 falls below the first predetermined temperature and stops when the water temperature exceeds the second predetermined temperature based on the measurement of the water temperature gauge TT3.
　雨水タンク１９は、鉛直方向において上部タンク１１、中部タンク１２，及び、下部タンク１３よりも上方に設けられ、雨水を溜めることができるものである。雨水タンク１９の底部には流路Ｈが接続している。 The rainwater tank 19 is provided above the upper tank 11, the middle tank 12, and the lower tank 13 in the vertical direction, and can store rainwater. A channel H is connected to the bottom of the rainwater tank 19 .
　雨水駆動揚水ポンプ２０は、鉛直方向において雨水タンク１９の下方に設けられ、雨水タンク１９から流路Ｈを通じて流入する雨水により動力を得て駆動するポンプである。 The rainwater-driven water pump 20 is provided below the rainwater tank 19 in the vertical direction, and is powered by the rainwater that flows from the rainwater tank 19 through the flow path H.
また、雨水駆動揚水ポンプ２０は流路Ｉに設けられている。流路Ｉは、流路Ｆの第１フルイダインポンプ１７よりも上流側から分岐したものであり、上部タンク１１に接続している。したがって、雨水駆動揚水ポンプ２０は、流路Ｉを通じて下部タンク１３の水を上部タンク１１に揚水することができる。これにより、上部タンク１１は、流路Ｆ，Ｉを介して下部タンク１３の下流側に設けられることとなり、下部タンク１３の水が流入されることとなる。なお、流路Ｉにおける雨水駆動揚水ポンプ２０よりも下流側には、流量計ＦＴ４が設けられている。 Also, a rainwater-driven water pump 20 is provided in the flow path I. As shown in FIG. The flow path I branches from the upstream side of the first fluid-in pump 17 of the flow path F and is connected to the upper tank 11 . Therefore, the rainwater-driven water pump 20 can pump the water in the lower tank 13 to the upper tank 11 through the channel I. As a result, the upper tank 11 is provided on the downstream side of the lower tank 13 via the flow paths F and I, and the water in the lower tank 13 flows into it. A flow meter FT4 is provided downstream of the rainwater-driven water pump 20 in the flow path I. As shown in FIG.
　下部タンク１３には、タンク内の水を外部に排出する排水管ＤＲが設けられている。排水管ＤＲには閉仕切弁Ｃ２、その下流側には逆止弁ＣＨ３が設けられており、さらにその下流側には、既に説明したように流路Ｋが合流している。 The lower tank 13 is provided with a drain pipe DR for discharging the water in the tank to the outside. The drain pipe DR is provided with a closing gate valve C2 and a check valve CH3 on the downstream side thereof.
　流路Ｋ、流路Ｍ、及び、排水管ＤＲにより、中部タンク１２、及び、下部タンク１３内の水を排出可能である。これらはメンテナンス時に排水するためのものである。 The water in the middle tank 12 and the lower tank 13 can be discharged by the flow path K, the flow path M, and the drain pipe DR. These are for draining water during maintenance.
　第１フルイダインポンプ１７、第２フルイダインポンプ１８には、それぞれ、水位計ＬＳ４，ＬＳ５、空気圧計ＰＴ４，ＰＴ５、温度計ＴＴ４，ＴＴ５、及び、流量計ＦＴ５，ＦＴ６が設けられている。これらの構成は、第１フルイダインポンプ１７、第２フルイダインポンプ１８の内部エネルギーの状態を監視するためのものである。既に説明したように、これらの構成により把握した内部エネルギーが低ければ、流量調整弁ＦＯ１の開度を小さくし、高すぎる場合は流量調整弁ＦＯ１の開度を大きくする。 The first fluidyne pump 17 and the second fluidyne pump 18 are provided with water level gauges LS4, LS5, air pressure gauges PT4, PT5, thermometers TT4, TT5, and flowmeters FT5, FT6, respectively. These configurations are for monitoring the state of internal energy of the first fluid-in pump 17 and the second fluid-in pump 18 . As already explained, if the internal energy grasped by these configurations is low, the degree of opening of the flow control valve FO1 is decreased, and if it is too high, the degree of opening of the flow control valve FO1 is increased.
　上部タンク１１は、第１通気管ＶＥ１により外部と連通しているため、空気圧が大気圧と等しくなっており、中部タンク１２及び下部タンク１３は、各通気管ＶＥ２，ＶＥ３，ＶＥ４により上部タンク１１と繋がっているため、やはり空気圧が大気圧と等しくなっている。 Since the upper tank 11 communicates with the outside through the first vent pipe VE1, the air pressure is equal to the atmospheric pressure. Because it is connected to , the air pressure is equal to the atmospheric pressure.
　なお、本実施例においては、上部タンク１１が設けられるものとして説明したが、本発明はこれに限定されるものではなく、上部タンク１１がなくとも成立する。すなわち、上部タンク１１、及び、それに付随する諸機構（第２フルダインポンプ１８、各計測器、各流路、各通気管、雨水タンク１９、雨水駆動揚水ポンプ２０等）を省略することもできる。 Although the present embodiment has been described with the upper tank 11 provided, the present invention is not limited to this, and can be established without the upper tank 11. That is, the upper tank 11 and associated mechanisms (the second full-dyne pump 18, each measuring instrument, each flow path, each ventilation pipe, the rainwater tank 19, the rainwater-driven pump 20, etc.) can be omitted. .
また、本実施例においては、補発電機１６が設けられるものとして説明したが、本発明はこれに限定されるものではなく、補発電機１６がなくとも成立する。すなわち、補発電機１６、及び、流路Ｂ２，Ｅを省略することもできる。 Further, in the present embodiment, the auxiliary power generator 16 is provided, but the present invention is not limited to this, and can be established without the auxiliary power generator 16 . That is, the auxiliary generator 16 and the flow paths B2, E can be omitted.
また、本実施例においては、雨水タンク１９、及び、雨水駆動揚水ポンプ２０が設けられるものとして説明したが、本発明はこれに限定されるものではなく、雨水タンク１９、及び、雨水駆動揚水ポンプ２０がなくとも成立する。すなわち、雨水タンク１９、雨水駆動揚水ポンプ２０、及び、流路Ｉを省略し、流路Ｌが流路Ｉに合流するのではなく、上部タンク１１に接続するものとすることもできる（ただし、既に説明したように、中部タンク１２等を省略する場合は、流路Ｌではなく流路Ｊが上部タンク１１に接続するようにする）。 Further, in this embodiment, the rainwater tank 19 and the rainwater-driven pump 20 are provided, but the present invention is not limited to this, and the rainwater tank 19 and the rainwater-driven pump are provided. It works even without 20. That is, the rainwater tank 19, the rainwater-driven pump 20, and the flow path I can be omitted, and the flow path L can be connected to the upper tank 11 instead of joining the flow path I (however, As already explained, when the middle tank 12 and the like are omitted, the flow path J instead of the flow path L is connected to the upper tank 11).
　以上が、本実施例に係る揚水発電システム１の構成についての説明である。以下では、本実施例に係る揚水発電システム１による処理の概要について、図２のフローチャートを用いて説明する。 The above is the description of the configuration of the pumped-storage power generation system 1 according to the present embodiment. Below, the outline of the processing by the pumped-storage power generation system 1 according to the present embodiment will be described using the flowchart of FIG. 2 .

　自動弁４７は、電磁弁４８の開閉動作により制御される。すなわち、電磁弁４８が開状態になると、計装空気が供給され、これにより、自動弁４７が開状態となる。一方、気体供給装置はサービスエアを供給するものである。すなわち、自動弁４７が開状態となると、気体供給装置から室Ｏへサービスエアが供給される。 The automatic valve 47 is controlled by opening and closing operations of the electromagnetic valve 48 . That is, when the electromagnetic valve 48 is opened, the instrument air is supplied, thereby opening the automatic valve 47 . On the other hand, the gas supply device supplies service air. That is, service air is supplied to the chamber O from the gas supply device when the automatic valve 47 is opened.
　第３放熱用ヒートシンク４６は、放熱用ループヒートパイプ４４上に設けられている（ただし、本実施例及び後述する実施例３においては、これをループヒートパイプではなくヒートパイプとしてもよい）。シリンダ４２は、開口部４２Ａより他端側の側壁４２Ｄの一部が第３放熱用ヒートシンク４６に接するようにして設けられている。また、側壁４２Ｄにおける、第３放熱用ヒートシンク４６との接触部分は、熱伝導材料により形成されているものとする。

It may consist of Alternatively, the function of the partition member 43D may be provided to the first piston heat sink 43B, and the partition member 43D may be omitted.
　すなわち、放熱部３３は、送熱機構２Ａに蓄積された熱を系外に放出可能とするものである。本実施例に係る揚水発電システム２を起動していない間においては、放熱部３３により放熱しておく。これにより安全に運用することができる。また、放熱部３３は、後述する温度センサＴＴ６によって高熱部１７Ｃの温度が異常に高くなった場合にも自動的に接続され、これにより安全な運転を行うことができる。 That is, the heat radiating section 33 can release the heat accumulated in the heat transfer mechanism 2A to the outside of the system. While the pumped-storage power generation system 2 according to the present embodiment is not activated, heat is radiated by the heat radiating section 33 . This allows safe operation. Further, the heat radiating section 33 is automatically connected even when the temperature of the high heat section 17C becomes abnormally high by a temperature sensor TT6, which will be described later, thereby enabling safe operation.
以上が、送熱機構２Ａの構成についての説明である。ただし、放熱部３３は、上述した機構の代わりに、第１放熱用ヒートシンク４１と第３放熱用ヒートシンク４６とを、例えば取っ手を取り付ける等により手動操作可能な熱伝導体にて接合状態と分離状態とに切り替えることで、放熱状態及び非放熱状態を実現するようにしてもよい。 The above is the description of the configuration of the heat transfer mechanism 2A. However, instead of the mechanism described above, the heat radiation part 33 is configured such that the first heat sink 41 and the third heat sink 46 are joined and separated by a thermal conductor that can be manually operated by, for example, attaching a handle. The heat dissipation state and the non-heat dissipation state may be realized by switching between and.
以下では、図４，５を用いて送熱機構２Ａによる大まかな動作について説明する。なお、図４のステップＳ１１～Ｓ１５は、通常運転時のフローチャートであり、図５のステップＳ２１～Ｓ２４は、放熱運転時のフローチャートである。 Below, the general operation of the heat transfer mechanism 2A will be described with reference to FIGS. Note that steps S11 to S15 in FIG. 4 are a flowchart for normal operation, and steps S21 to S24 in FIG. 5 are a flowchart for heat dissipation operation.
　ステップＳ１１では、電磁弁４８が励磁され開状態となることで、計装空気が自動弁４７に導かれ、自動弁４７が開状態となる。 In step S11, the solenoid valve 48 is energized and opened, so that the instrumentation air is guided to the automatic valve 47, and the automatic valve 47 is opened.
　ステップＳ１２では、第１放熱部用通気管ＶＥ５を通じてサービスエアが室Ｏ内に供給され、第１ピストン用ヒートシンク４３Ｂがシリンダ４２の他端側に押圧されることで、第１ピストン用ヒートシンク４３Ｂと第１放熱用ヒートシンク４１とが、シリンダ４２の軸心方向において離隔状態となる。 In step S12, service air is supplied into the chamber O through the first heat radiating section vent pipe VE5, and the first piston heat sink 43B is pressed against the other end side of the cylinder 42, thereby causing the first piston heat sink 43B and the The first heat sink for heat radiation 41 is separated from the first heat sink 41 in the axial direction of the cylinder 42 .
　ステップＳ１３では、加熱部３２により入力された熱量が、吸熱用ループヒートパイプ３１に伝達される。 In step S13, the amount of heat input from the heating unit 32 is transmitted to the loop heat pipe 31 for endothermic absorption.
　ステップＳ１４では、吸熱用ループヒートパイプ３１により第１フルイダインポンプ１７の高熱部１７Ｃに熱負荷を与える。 In step S14, a heat load is applied to the high heat portion 17C of the first fluidyne pump 17 by the loop heat pipe 31 for heat absorption.
　ステップＳ１５では、第１フルイダインポンプ１７が駆動し、実施例１にて説明した図２のステップＳ２のとおり発電する。 In step S15, the first fluidyne pump 17 is driven to generate power as in step S2 of FIG. 2 described in the first embodiment.
　一方、ステップＳ２１では、電磁弁４８（３方弁）が非励磁となり二次側の計装空気配管は大気圧となる。そして単作動の自動弁４７が閉状態となる。 On the other hand, in step S21, the electromagnetic valve 48 (three-way valve) is de-energized, and the secondary side instrumentation air pipe becomes atmospheric pressure. Then, the single-acting automatic valve 47 is closed.
　ステップＳ２２では、第１放熱部用通気管ＶＥ５を通じてサービスエアが室Ｏから排出され、ばね４３Ｅの力によってピストン４３が動き、第１ピストン用ヒートシンク４３Ｂがシリンダ４２の他端側に押圧されることで、第１ピストン用ヒートシンク４３Ｂと第１放熱用ヒートシンク４１とが、シリンダ４２の軸心方向において重複状態となる。 In step S22, the service air is discharged from the chamber O through the first heat radiator vent pipe VE5, the piston 43 is moved by the force of the spring 43E, and the first piston heat sink 43B is pressed against the other end side of the cylinder 42. Thus, the first piston heat sink 43B and the first heat radiation heat sink 41 overlap each other in the axial direction of the cylinder 42 .
　ステップＳ２３（吸熱用ループヒートパイプ３１からシリンダ４２及びピストン４３へ伝熱）では、吸熱用ループヒートパイプ３１中の熱が、第１放熱用ヒートシンク４１から、側壁４２Ｂの熱伝導材料部分を介して第１ピストン用ヒートシンク４３Ｂに伝達される。第１ピストン用ヒートシンク４３Ｂに伝達された熱は、ピストン用ヒートパイプ４３Ａ、第２ピストン用ヒートシンク４３Ｃへと伝わる。 In step S23 (heat transfer from the endothermic loop heat pipe 31 to the cylinder 42 and the piston 43), the heat in the endothermic loop heat pipe 31 is transferred from the first heat radiating heat sink 41 through the heat conductive material portion of the side wall 42B. It is transmitted to the first piston heat sink 43B. The heat transmitted to the first piston heat sink 43B is transmitted to the piston heat pipe 43A and the second piston heat sink 43C.
　ステップＳ２４（シリンダ４２及びピストン４３から放熱用ループヒートパイプ４４へ伝熱）では、第２ピストン用ヒートシンク４３Ｃの熱が、側壁４２Ｄの熱伝導材料分を介して第３放熱用ヒートシンク４６、そして放熱用ループヒートパイプ４４に伝達され、その後、放熱用ループヒートパイプ４４上の第２放熱用ヒートシンク４５から外部へ放熱される。
以上が、本実施例に係る揚水発電システム２による大まかな動作の説明である。 In step S24 (heat transfer from the cylinder 42 and the piston 43 to the heat radiation loop heat pipe 44), the heat of the second piston heat sink 43C is transferred to the third heat radiation heat sink 46 through the heat conductive material of the side wall 42D, and then to the heat radiation. After that, the heat is radiated to the outside from the second heat sink 45 on the loop heat pipe 44 for heat dissipation.
The above is the general description of the operation of the pumped-storage power generation system 2 according to the present embodiment.
　本実施例に係る揚水発電システム２では、第１フルイダインポンプ１７の高熱部１７Ｃ（及び、第２フルイダインポンプ１８の高熱部）に熱負荷を与えることができる吸熱用ループヒートパイプ３１と、吸熱用ループヒートパイプ３１に熱を入力する加熱部３２と、吸熱用ループヒートパイプ３１から熱を放出することができる放熱部３３とを備えているので、実施例１で説明した第１フルイダインポンプ１７（第２フルイダインポンプ１８）を簡便に駆動することができるとともに、吸熱用ループヒートパイプ３１中の不要な熱を外部に放出することができる。 In the pumped-storage power generation system 2 according to the present embodiment, a heat absorption loop heat pipe 31 capable of applying a heat load to the high heat portion 17C of the first fluidyne pump 17 (and the high heat portion of the second fluidyne pump 18), Since the heating portion 32 for inputting heat to the endothermic loop heat pipe 31 and the heat radiating portion 33 for releasing heat from the endothermic loop heat pipe 31 are provided, the first fluidyne as described in the first embodiment is provided. The pump 17 (second fluidyne pump 18) can be easily driven, and unnecessary heat in the endothermic loop heat pipe 31 can be released to the outside.
本実施例に係る揚水発電システム２では、放熱部３３は、熱を放出する第２放熱用ヒートシンク４５を有する放熱用ループヒートパイプ４４と、吸熱用ループヒートパイプ３１の熱を放熱用ループヒートパイプ４４に伝達可能なシリンダ４２及びピストン４３とを備えているので、簡便に放熱することができる。 In the pumped-storage power generation system 2 according to the present embodiment, the heat dissipation unit 33 includes a heat dissipation loop heat pipe 44 having a second heat dissipation heat sink 45 for dissipating heat, and a heat dissipation loop heat pipe 44 for dissipating heat from the heat absorption loop heat pipe 31 . Since the cylinder 42 and the piston 43 that can be transmitted to 44 are provided, heat can be easily dissipated.

熱交換用ヒートシンク５１は、吸熱用ループヒートパイプ３１と環状パイプ５２とを架設するようにして設置されている。 The heat exchange heat sink 51 is installed so as to bridge the endothermic loop heat pipe 31 and the annular pipe 52 .
環状パイプ５２には、さらに圧縮ポンプ５３、減圧弁５４、及び、高熱部１７Ｃが設けられ、高熱部１７Ｃに熱負荷を与えることができる。なお、熱交換用ヒートシンク５１、及び、環状パイプ５２の各部材間には、それぞれ温度センサＴＴ６～ＴＴ９が設けられている。 The annular pipe 52 is further provided with a compression pump 53, a pressure reducing valve 54, and a high heat section 17C, so that a heat load can be applied to the high heat section 17C. Temperature sensors TT6 to TT9 are provided between the members of the heat exchange heat sink 51 and the annular pipe 52, respectively.
　熱交換用ヒートシンク５１は、吸熱用ループヒートパイプ３１の熱を環状パイプ５２に伝達するものである。また、環状パイプ５２内は圧縮ポンプ５３により熱媒体が循環している。吸熱用ループヒートパイプ３１から熱交換用ヒートシンク５１に伝達された熱は、この熱媒体に与えられる。 The heat exchange heat sink 51 transfers heat from the endothermic loop heat pipe 31 to the annular pipe 52 . A heat medium is circulated in the annular pipe 52 by a compression pump 53 . The heat transferred from the endothermic loop heat pipe 31 to the heat exchange heat sink 51 is given to this heat medium.
　また、圧縮ポンプ５３により、環状パイプ５２内の熱媒体はさらに加熱され、その下流側にある第１フルイダインポンプ１７（第２フルイダインポンプ１８）の高熱部１７Ｃに熱負荷を与えることができる。 Further, the heat medium in the annular pipe 52 is further heated by the compression pump 53, and a heat load can be applied to the high heat portion 17C of the first fluidy-in pump 17 (second fluidy-in pump 18) on the downstream side. .
　減圧弁５４は、第１フルイダインポンプ１７の高熱部１７Ｃよりも下流側に設けられている。背圧弁５４の圧縮ポンプ５３で加圧された熱媒体が減圧弁５４の一次側まで高圧状態を保ち、減圧弁５４の二次側にて膨張させることで熱媒体の温度が低下し、吸熱用ループヒートパイプ３１から熱媒体に効率よく熱を移動させる。
　以上が、本実施例における送熱機構３Ａの構成の一部についての説明である。 The pressure reducing valve 54 is provided downstream of the high heat portion 17</b>C of the first fluidy-in pump 17 . The heat medium pressurized by the compression pump 53 of the back pressure valve 54 maintains a high pressure state up to the primary side of the pressure reducing valve 54, and expands on the secondary side of the pressure reducing valve 54, thereby lowering the temperature of the heat medium. To efficiently transfer heat from a loop heat pipe 31 to a heat medium.
The above is a description of part of the configuration of the heat transfer mechanism 3A in this embodiment.
　このようにして本実施例に係る揚水発電システム３では、圧縮ポンプ５３を有し、第１フルイダインポンプ１７の高熱部１７Ｃ（及び、第２フルイダインポンプ１８の高熱部）に熱負荷を与えることができる環状パイプ５２と、熱交換用ヒートシンク５１を介して環状パイプ５２に熱が伝達される吸熱用ループヒートパイプ３１と、吸熱用ループヒートパイプ３１に熱を入力する加熱部３２と、吸熱用ループヒートパイプ３１から熱を放出することができる放熱部３３とを備えているので、実施例２の作用効果に加え、装置を自動化させるにあたって、安定して装置を動かし続けることが可能となる。また、圧縮ポンプ５３を設けることで加熱部３２からフルイダインポンプ１７，１８へ与えられる熱量を増加させることができる。 In this way, the pumped-storage power generation system 3 according to this embodiment has the compression pump 53, and applies heat load to the high heat portion 17C of the first fluidyne pump 17 (and the high heat portion of the second fluidyne pump 18). a heat-absorbing loop heat pipe 31 through which heat is transferred to the annular pipe 52 via the heat exchange heat sink 51; a heating unit 32 that inputs heat to the heat-absorbing loop heat pipe 31; Since it is equipped with a heat radiating part 33 capable of radiating heat from the loop heat pipe 31, in addition to the effects of the second embodiment, when automating the device, it is possible to keep the device running stably. . Also, by providing the compression pump 53, the amount of heat given from the heating unit 32 to the fluidyne pumps 17 and 18 can be increased.
