Description

液体浮力を利用した揚水式発電装置Pumping generator using liquid buoyancy
本発明は、液体浮力を利用した揚水式発電装置に関する。詳しくは、浮力用水の水位を変化させることにより浮力用水が浮水槽に与える浮力を利用して浮水槽を昇降させ、浮水槽の上部の発電用水を上部発電用水槽に移動させる液体浮力を利用した揚水式発電装置に関する。 TECHNICAL FIELD The present invention relates to a pumped storage system using liquid buoyancy. Specifically, by changing the water level of the buoyancy water, the buoyancy force that the buoyancy water gives to the floating water tank is used to move the floating water tank up and down to move the upper generation water of the floating water tank to the upper power generation water tank.

従来の揚水式発電装置としては、揚水ポンプまたはバケット等による装置が一般的であったが、本願出願人は、液体浮力を利用した新たな揚水式発電装置をすでに提案した（特許文献１参照）。 Although a conventional apparatus using a pumping pump or a bucket was generally used as a conventional pumping system, the present applicant has already proposed a new pumping system using liquid buoyancy (see Patent Document 1). .

一般的に、液体の比重より小さい比重を持つ物体を液体に浮かべると、物体は浮力を受け、液面が上昇すると物体も上昇し、液面が下降すると物体も下降する。液面を昇降させるのに要する液体のエネルギーは上昇と下降とで同量であり、これを循環できれば省エネルギーが可能である。そして、高低差のある運河・河川等（パナマ運河・中国長江宜昌）での船舶の垂直通行は自然界の循環エネルギーを有しているので可能であり、しかも環境にもよい。 Generally, when an object having a specific gravity smaller than the specific gravity of the liquid floats on the liquid, the object receives buoyancy, and when the liquid level rises, the object also rises, and when the liquid level falls, the object also descends. The energy of the liquid required to raise and lower the liquid level is the same amount as rising and lowering, and if it can be circulated, energy saving is possible. And, vertical passage of the ship in canal, river, etc. (Panama canal, Chinese Changjiang River Yangchang) with the height difference is possible because it has circulating energy in the natural world, and it is also good for the environment.

以下、本発明の実施形態について図面を参照しながら詳細に説明する。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
図１および図２は、本発明の実施例１に係る液体浮力を利用した揚水式発電装置の要部を示し、Ａがガイド付浮水部、Ｂが水車式発電部、Ｃが浮力用水給排水部、Ｄがパイプ付揚水部である。 1 and 2 show the main part of a pumped storage system using liquid buoyancy according to the first embodiment of the present invention, wherein A is a guide float water part, B is a water turbine power generation part, and C is a water supply and drainage part for buoyancy , D is a piped water pumping section.
ガイド付浮水部Ａは、複数の中間浮力用水排水バルブ１７および下位浮力用水排水バルブ１４を付設する有底四角筒状の水槽１と、水槽１に浮水用水間隙を介して昇降自在に遊嵌する浮水槽浮力用密閉空間部３および浮水槽浮力用密閉空間部３の上に載置されてなり上下に複数の発電用水給水バルブを付設する発電用水揚水槽部４からなる浮水槽２と、発電用水揚水槽部４を昇降自在に案内する直方体枠状のガイド部材５とから、その主要部が構成されている。 The guided floater A loosely fits to the water tank 1 via the floatation water gap so as to freely move up and down with the bottomed square cylindrical water tank 1 having the plurality of intermediate buoyancy water drainage valves 17 and the lower buoyancy water drainage valves 14 attached. A floating water tank 2 comprising a generating water tank 4 disposed on the floating water tank buoyancy sealed space 3 and the floating water tank buoyancy sealed space 3 and having a plurality of water supply water supply valves for power generation vertically The main part is comprised from the rectangular parallelepiped frame-shaped guide member 5 which guides the lifting water tank part 4 so that raising / lowering is possible.
図１０を参照すると、浮水槽浮力用密閉空間部３は、水槽１に浮水用水間隙を介して昇降自在に遊嵌するような直方体状に形成さ、浮水槽浮力用密閉空間部３の上に外径が一回り大きい有底四角凹皿状の発電用水揚水槽部４が一体的に載置されている。浮水槽浮力用密閉空間部３は、水槽１内の浮力用水に浮かべられて浮水槽２の自重と発電用水揚水槽部４に貯水される発電用水の重量とに対向する浮力を生じさせる役目をする。なお、浮水槽浮力用密閉空間部３には、水素ガス,ヘリウムガス等の空気より軽い気体を封入するようにしてもよい。このようにすれば、浮水槽２全体の比重を低下させることができるので、発電用水揚水槽部４により多量の発電用水を貯水することが可能になる。発電用水揚水槽部４には、上部発電用水槽８に発電用水を給水する上下２つの発電用水給水バルブ６が付設されている。なお、水槽１の内壁に浮水槽浮力用密閉空間部３を昇降自在に案内するレールまたはコロ等でなるガイド（図示せず）が設けられている。また、ガイド部材５の内壁にも発電用水揚水槽部４を昇降自在に案内するレールまたはコロ（図示せず）等でなるガイドが設けられている。これらにより、浮水槽２の昇降時の横ブレを少なくして、安定した昇降を行うことができる。 Referring to FIG. 10, the floating water tank buoyancy sealed space 3 is formed in a rectangular parallelepiped shape so as to be freely fitted to the water tank 1 via the floating water gap, and is formed above the floating water tank buoyancy sealed space 3. A bottomed square concave plate-like power generation water tank 4 with a large outer diameter is mounted integrally. The floating water tank buoyancy sealed space 3 has a function to generate a buoyancy that is opposed to the weight of the floating water tank 2 and the weight of the power generation water stored in the power generation water tank 4 by being floated on the floating water in the water tank 1. Do. A gas lighter than air such as hydrogen gas or helium gas may be enclosed in the floating water tank buoyancy sealed space 3. In this way, since the specific gravity of the entire floating water tank 2 can be reduced, a large amount of water for power generation can be stored by the power generation water tank portion 4. The upper and lower power generation water supply tank 6 is additionally provided with two upper and lower power supply water supply valves 6 for supplying power generation water to the upper power generation water tank 8. In addition, a guide (not shown) made of a rail, a roller, or the like is provided on the inner wall of the water tank 1 for guiding the floating water tank buoyancy sealed space 3 up and down. Further, on the inner wall of the guide member 5, a guide formed of a rail or a roller (not shown) or the like for guiding the power generation water tank portion 4 so as to be moved up and down is provided. As a result, it is possible to reduce the lateral deviation at the time of lifting and lowering of the floating water tank 2 and perform stable lifting and lowering.
水車式発電部Ｂは、ガイド部材５の一側方に配置され、水圧管９を斜め下方に垂下するように付設してなる上部発電用水槽８と、上部発電用水槽８から水圧管９を通じて放流される発電用水により発電をする水車１０および発電機１１と、水車１０および発電機１１により発電に使用された発電用水を貯水するとともに上下２つの発電用水排水バルブ１２を付設した下部発電用水槽７とから、その主要部が構成されている。なお、図２中の符号３１は浮水槽制御盤を、３２は発電機盤をそれぞれ示す。 The water turbine-type power generation unit B is disposed on one side of the guide member 5 and includes an upper power generation water tank 8 formed by attaching the water pressure pipe 9 so as to hang obliquely downward and a water pressure pipe 9 from the upper power generation water tank 8. A lower power generation water tank that stores water for power generation used for power generation by the water for power generation discharged and power generation water used for power generation by the water turbine 10 and the power generator 11 and additionally has two water discharge valves 12 for power generation vertically The main part is composed of 7). In addition, the code | symbol 31 in FIG. 2 shows a floating water tank control board, 32 shows a generator board, respectively.
浮力用水給排水部Ｃは、水槽１の左右両側方に分散して配置され、水槽１に浮力用水を給水する上部浮力用水給水バルブ２１を付設する上部浮力用水槽２０と、水槽１に浮力用水を給水する中間浮力用水給水バルブ１６を付設する複数の中間浮力用水槽１５と、下部浮力用水槽１３とから、その主要部が構成されている。中間浮力用水槽１５間の間隔を詰めるとともに複数の中間浮力用水槽１５を水槽１の左右両側方に分散して配置することにより、１つの中間浮力用水槽１５の容量を小さくすることができ、中間浮力用水槽１５の多数化小容量化により下部浮力用水槽１３の容量も小さくなる。その結果、下部浮力用水槽１３から浮力用水を上部浮力用水槽２０に揚水するための揚水ポンプ１８の容量も小さくなる。複数の中間浮力用水槽１５には、水槽１内の浮力用水が複数の中間浮力用水排水バルブ１７からそれぞれ排水されるようになっている。また、下部浮力用水槽１３には、水槽１内の浮力用水が下部浮力用水排水バルブ１４から排水されるようになっている。なお、上部浮力用水槽２０の上部浮力用水給水バルブ２１および中間浮力用水槽１５の中間浮力用水給水バルブ１６のそれぞれにマイクロ発電機３０を付設し、上部浮力用水槽２０および中間浮力用水槽１５から浮力用水を水槽１に給水するときにも各マイクロ発電機３０により発電が行われるようになっている。また、水槽１の中間浮力用水排水バルブ１７および下位浮力用水排水バルブ１４のそれぞれにマイクロ発電機３０を付設し、水槽１から浮力用水を中間浮力用水槽１５および下部浮力用水槽１３に排水するときにも各マイクロ発電機３０により発電が行われるようになっている。 The buoyancy water supply and drainage section C is disposed on both the left and right sides of the water tank 1, and is provided with an upper buoyancy water tank 20 having an upper buoyancy water supply valve 21 for supplying buoyancy water to the water tank 1, and water for buoyancy in the water tank 1. The main part is constituted by a plurality of intermediate buoyancy water tanks 15 to which an intermediate buoyancy water supply valve 16 for supplying water is attached and a lower buoyancy water tank 13. By reducing the distance between the intermediate buoyancy water tanks 15 and distributing the plurality of intermediate buoyancy water tanks 15 on both the left and right sides of the water tank 1, the capacity of one intermediate buoyancy water tank 15 can be reduced. The capacity reduction of the lower buoyancy water tank 13 is also reduced by increasing the number and reducing the capacity of the intermediate buoyancy water tank 15. As a result, the capacity of the pumping pump 18 for pumping the buoyancy water from the lower buoyancy tank 13 to the upper buoyancy tank 20 also decreases. In the plurality of intermediate buoyancy water tanks 15, the buoyancy water in the water tank 1 is drained from the plurality of intermediate buoyancy water drainage valves 17, respectively. Further, the buoyancy water in the water tank 1 is drained from the lower buoyancy water drain valve 14 to the lower buoyancy water tank 13. A microgenerator 30 is attached to each of the upper buoyancy water supply valve 21 of the upper buoyancy water tank 20 and the intermediate buoyancy water supply valve 16 of the intermediate buoyancy water tank 15 from the upper buoyancy water tank 20 and the intermediate buoyancy water tank 15. Also when the buoyancy water is supplied to the water tank 1, power is generated by each micro generator 30. When the micro generator 30 is attached to each of the intermediate buoyancy water drainage valve 17 and the lower buoyancy water drainage valve 14 of the water tank 1 and the buoyancy water is drained from the water tank 1 to the intermediate buoyancy water tank 15 and the lower buoyancy water tank 13 Also, power is generated by each micro generator 30.

パイプ付揚水部Ｄは、下部浮力用水槽１３と上部浮力用水槽２０とを連結する揚水管１９と、揚水管１９を通じて下部浮力用水槽１３から浮力用水を上部浮力用水槽２０へ揚水する揚水ポンプ１８とから、その主要部が構成されている。 The piped pumping section D is a pumping pipe for pumping buoyancy water from the lower buoyancy tank 13 to the upper buoyancy water tank 20 through the pumping pipe 19 connecting the lower buoyancy water tank 13 and the upper buoyancy water tank 20 and the pumping tube 19. The main part consists of 18 and the like.
なお、各給排水バルブの開閉は液面リレーおよび電磁弁（ともに図示せず）の操作により行い、発電用水給水バルブ６および発電用水排水バルブ１２の吐出管部分は、フレキシブルパイプを用いて各水槽と吐出管との物理的な干渉を避けるように構成されている。 In addition, opening and closing of each water supply and drainage valve is performed by the operation of the liquid level relay and the solenoid valve (both not shown), and the discharge pipe part of the water supply valve 6 for power generation and water discharge valve 12 for power generation use flexible pipe It is configured to avoid physical interference with the discharge pipe.
次に、このように構成された本実施例１に係る液体浮力を利用した揚水式発電装置の動作について説明する。 Next, the operation of the pumped storage system using the liquid buoyancy according to the first embodiment configured as described above will be described.
まず、図２に示すような発電用水揚水槽部４ならびに上部浮力用水槽２０および全ての中間浮力用水槽１５の無水状態から、図３に示すように、発電用水揚水槽部４に発電用水を外部から貯水するとともに、上部浮力用水槽２０および全ての中間浮力用水槽１５に浮力用水を外部から貯水する。このとき、浮水槽２が浮かばない程度に水槽１内にも若干の浮力用水を貯水しておいてもよい。 First, from the anhydrous state of the power generation water tank 4 as shown in FIG. 2, the upper buoyancy water tank 20 and all the intermediate buoyancy water tanks 15, as shown in FIG. While storing water from the outside, the water for buoyancy is stored from the outside in the upper buoyancy water tank 20 and all the intermediate buoyancy water tanks 15. At this time, some buoyancy water may be stored in the water tank 1 to such an extent that the floating water tank 2 does not float.
次に、図３に示すように、発電用水揚水槽部４内が発電用水で満水状態になるとともに上部浮力用水槽２０および全ての中間浮力用水槽１５内が浮力用水で満水状態になったならば、下位側から中間浮力用水槽１５の中間浮力用水給水バルブ１６を順次開放し、浮力用水を水槽１内へ順次給水する。すると、水槽１内の浮力用水の水位が次第に上がり、浮力用水から受ける浮力により浮水槽浮力用密閉空間部３が浮かんで、浮水槽２が徐々に上昇し始める。 Next, as shown in FIG. 3, when the generating water tank 4 is filled with the generating water and the upper buoyancy water tank 20 and all the intermediate buoyancy water tanks 15 are filled with the buoyancy water. For example, the intermediate buoyancy water supply valve 16 of the intermediate buoyancy water tank 15 is sequentially opened from the lower side, and the buoyancy water is sequentially supplied to the water tank 1. Then, the water level of the buoyancy water in the water tank 1 gradually rises, and the floating water tank buoyancy sealing space 3 floats by the buoyancy received from the buoyancy water, and the floating water tank 2 starts to gradually rise.
続いて、図４に示すように、さらに上位側の中間浮力用水槽１５の中間浮力用水給水バルブ１６を順次開放すると、水槽１内の浮力用水の水位が上がり、浮水槽２が上昇して発電用水揚水槽部４がガイド部材５に案内されながら上昇することにより、発電用水を貯水する発電用水揚水槽部４が上部発電用水槽８へ次第に近づいていく。 Subsequently, as shown in FIG. 4, when the intermediate buoyancy water supply valve 16 of the upper intermediate buoyancy water tank 15 is sequentially opened, the water level of the buoyancy water in the water tank 1 rises, and the floating water tank 2 rises to generate electricity. By the lifting water tank portion 4 rising while being guided by the guide member 5, the power generation lifting water tank portion 4 storing the power generation water gradually approaches the upper power generation water tank 8.
次に、図５に示すように、発電用水揚水槽部４の上位側の発電用水給水バルブ６が上部発電用水槽８の上縁の高さ位置を越えたときに、その発電用水給水バルブ６を開放して発電用水揚水槽部４内の発電用水を上部発電用水槽８へ給水する。すると、発電用水揚水槽部４内の発電用水の重量が減ることにより、浮水槽２の総重量が減り、浮水槽２がさらに上昇する。 Next, as shown in FIG. 5, when the water supply valve 6 for power generation on the upper side of the water generation water tank 4 for generation exceeds the height position of the upper edge of the water tank 8 for upper power generation, the water supply valve 6 for power generation is generated. To supply water for power generation in the power generation water tank 4 to the upper power generation water tank 8. Then, the weight of the power generation water in the power generation water tank portion 4 decreases, so the total weight of the floating water tank 2 decreases, and the floating water tank 2 further rises.
続いて、図６に示すように、前記と同様にして、下位側の発電用水給水バルブ６が上部発電用水槽８の上縁の高さ位置を越えたときに、その発電用水給水バルブ６を開放して、発電用水揚水槽部４内の発電用水を上部発電用水槽８へ給水する。すると、浮水槽２はさらに上昇する。 Subsequently, as shown in FIG. 6, when the water supply valve 6 for power generation on the lower side exceeds the height position of the upper edge of the upper power generation water tank 8, the water supply valve 6 for power generation is The power generation water in the power generation water tank portion 4 is supplied to the upper power generation water tank 8 by opening. Then, the floating water tank 2 further rises.
他方、浮水槽２の自重等があるので、上位側の中間浮力用水槽１５の中間浮力用水給水バルブ１６および上部浮力用水槽２０の上部浮力用水給水バルブ２１を開放して、中間浮力用水槽１５および上部浮力用水槽２０内の浮力用水を全て水槽１に給水する。すると、浮水槽２は最上位にまで上昇し、発電用水揚水槽部４内の発電用水が全て上部発電用水槽８に給水される。 On the other hand, since the floating tank 2 has its own weight, etc., the intermediate buoyancy water supply valve 16 of the upper intermediate buoyancy water tank 15 and the upper buoyancy water supply valve 21 of the upper buoyancy tank 20 are opened. And all the buoyancy water in the upper buoyancy water tank 20 is supplied to the water tank 1. Then, the floating water tank 2 ascends to the uppermost position, and all the power generation water in the power generation water tank 4 is supplied to the upper power generation water tank 8.
そして、上部発電用水槽８に給水された発電用水を上部発電用水槽８から水圧管９を通じて放流させることにより、水車１０および発電機１１により発電が行われる。水車１０および発電機１１により発電に使用された発電用水は、下部発電用水槽７に貯水される。 Then, the power generation water supplied to the upper power generation water tank 8 is discharged from the upper power generation water tank 8 through the hydraulic pipe 9, whereby power generation is performed by the water turbine 10 and the generator 11. Water for power generation used for power generation by the water turbine 10 and the generator 11 is stored in the lower power generation water tank 7.
次に、図７に示すように、発電用水揚水槽部４内の発電用水を全て排水した浮水槽２を下降させるため、水槽１の中間浮力用水排水バルブ１７を上位側から順次開放して、水槽１内の浮力用水を中間浮力用水槽１５へ順次排水する。すると、水槽１内の浮力用水の水位が下がり、浮水槽２は下降する。 Next, as shown in FIG. 7, in order to lower the floating water tank 2 draining all the power generation water in the power generation water tank 4, the intermediate buoyancy water drain valve 17 of the water tank 1 is sequentially opened from the upper side, The buoyancy water in the water tank 1 is sequentially drained to the intermediate buoyancy water tank 15. Then, the water level of the buoyancy water in the water tank 1 falls, and the floating water tank 2 descends.
続いて、図８に示すように、水槽１の下部浮力用水排水バルブ１４を開放して、水槽１内の浮力用水を下部浮力用水槽１３に排水して浮水槽２を最下位まで下降させる。また、下部発電用水槽７の発電用水排水バルブ１２を開放して、下部発電用水槽７内の発電用水を発電用水揚水槽部４に排水する。 Subsequently, as shown in FIG. 8, the lower buoyancy water drain valve 14 of the water tank 1 is opened to drain the buoyancy water in the water tank 1 to the lower buoyancy water tank 13 to lower the floating water tank 2 to the lowest position. Further, the power generation water drainage valve 12 of the lower power generation water tank 7 is opened to drain the power generation water in the lower power generation water tank 7 to the power generation water tank portion 4.
そして、図９に示すように、下部浮力用水槽１３内の浮力用水を揚水ポンプ１８で揚水管１９を通じて上部浮力用水槽２０に揚水して下部浮力用水槽１３内を無水状態にする。 Then, as shown in FIG. 9, the buoyancy water in the lower buoyancy water tank 13 is pumped up to the upper buoyancy water tank 20 through the pumping pipe 19 by the pumping pump 18 to make the lower buoyancy water tank 13 anhydrous.
以上の一連の動作で一回の発電工程が終了し、この発電工程を繰り返すことにより連続に発電が行われる。 One power generation process is completed by the above series of operations, and power generation is continuously performed by repeating this power generation process.
