Description
本発明は、火力発電所や原子力発電所、水力発電所、工場など大量の冷却水を使用する施設の落差の少ない放水路を流れる水流の運動エネルギーを連続して有効に利用し効率良く水車・発電機を動作せしめることによって有効に電力エネルギーを得ることができ実用性、有用性に富む小水力発電システムに関する。 The present invention continuously and effectively uses the kinetic energy of the water flow flowing through the discharge channel with a small head of a facility using a large amount of cooling water such as a thermal power plant, nuclear power plant, hydroelectric power plant, factory, etc. The present invention relates to a small hydroelectric power generation system that can effectively obtain electric power energy by operating a generator and is highly practical and useful.
従来において、工場などの放水路や河川等に流れる水流や潮流の持つ運動エネルギーを利用して水車を回転させ、その回転を増速して発電機に伝達し、電気エネルギーに変換して発電する方法ないし装置としては、例えば特開2006-132344号（特許文献１）、特開2004-324518号（特許文献２）、特開2008-19879号（特許文献３）記載のもの等がある。 Conventionally, a turbine is rotated by using the kinetic energy of the water flow and tidal current flowing in a spillway or river of a factory, etc., and the rotation is accelerated and transmitted to a generator, which is converted into electric energy to generate electricity. Examples of methods and apparatuses include those described in JP-A-2006-132344 (Patent Document 1), JP-A-2004-324518 (Patent Document 2), JP-A-2008-19879 (Patent Document 3), and the like.
しかし前記の特許文献１、２、３に係る先行技術は、放水路の水流等の持つ運動エネルギーの利用ないし活用の仕方や水車を回転させるエネルギーの増大の仕方や水車等を装備する架台の活用の仕方等に工夫が今一で、水流の持つ運動エネルギーを電力エネルギーに変換する上においてその効率的な有効利用の面であまり良好ではないという難点を有していた。 However, the prior arts disclosed in Patent Documents 1, 2, and 3 described above are based on how to use or utilize the kinetic energy of the water flow in the water discharge channel, how to increase the energy for rotating the water wheel, and how to use the gantry equipped with the water wheel. However, there is a problem that it is not so good in terms of efficient and effective use in converting kinetic energy of water flow into electric power energy.
しかして、特許文献１記載のものにおいては、単に水路を流れる水流の運動エネルギーで水車を回転して得られた回転エネルギーを通常の増速機構を介して発電機に送り電気エネルギーに変換しようとするものであるから、水路の水流の持つ運動エネルギーを単に一次的に利用しているに過ぎず、その効率的な有効利用を図るという面では今一工夫が足らず、そのため発電量に限界があり、高出力の電力の期待はできない。 Therefore, in the thing of patent document 1, it is going to send the rotational energy obtained by rotating a water turbine with the kinetic energy of the water flow which flows through a water channel to a generator through a normal speed-up mechanism, and to convert into electric energy. Therefore, the kinetic energy of the water flow in the waterway is only used primarily, and there is not enough ingenuity in terms of its efficient and effective use, so there is a limit to the amount of power generation. Can not expect high power output.
また、特許文献２記載のものにおいては、水流中に係留する浮体１０の構造とそれに付設する水車２０の付設位置との関係で、水流の流速の変化に拘わらず水車の水中での作動面積を変化させることができるが、潮の干満による放水路の水位変化に拘わらず水車を常に水中に配置せしめるようになすという点に対処することができず、そして発電量にも多くを期待できないという問題点がある。 Moreover, in the thing of patent document 2, the working area in water of a water turbine is set to the structure of the floating body 10 moored in a water flow, and the attachment position of the water wheel 20 attached to it, irrespective of the change of the flow velocity of a water flow. Although it can be changed, it cannot cope with the point that the turbine is always placed in the water regardless of the change in the water level of the discharge channel due to the tides and the amount of power generation can not be expected There is a point.
更に、特許文献３記載のものにおいては、放水路の水流の流速を増大させて水車発電機を駆動し電力を得ようとするものであるが、回転羽根の径を異にし、回転羽根のブレード断面にポンプを介して水を噴射するノズルを複数備えたプロペラ水車を３基、水流方向に回転羽根の径が次第に大となるように直列に配置して、水流により水車を回転させるに従って流速が次第に増加するようになし、それを最後尾の発電機に与えて発電するようになしたものであるから、流速の増大を図るための構造が些か複雑化し、そのため放水路内の水流の持つ運動エネルギーの効率的な有効利用という面ではあまり良好とは云い難いところがある。 Furthermore, in the thing of patent document 3, it is trying to obtain the electric power by driving the water turbine generator by increasing the flow velocity of the water flow in the water discharge channel. Three propeller turbines equipped with a plurality of nozzles for injecting water through a pump in the cross section are arranged in series so that the diameter of the rotating blades gradually increases in the water flow direction, and the flow velocity increases as the water turbine is rotated by the water flow. The structure for increasing the flow velocity is slightly complicated because it is gradually increased, and it is applied to the last generator to generate electricity, so that the water flow in the discharge channel has In terms of efficient and effective use of kinetic energy, it is difficult to say that it is very good.
本発明は、斯かる先行技術の持つ諸難点に鑑みなされたもので、原子力発電所、火力発電所、水力発電所、工場などの冷却水放水路を流れる水流の運動エネルギーを連続して有効に利用し効率良く水車・発電機を動作せしめることによって有効にに電力エネルギーを得ることができ実用性、有用性に富む小水力発電システムを提供することを目的とするものである。 The present invention has been made in view of the various disadvantages of such prior art, and continuously and effectively uses the kinetic energy of a water flow flowing through a cooling water discharge channel of a nuclear power plant, a thermal power plant, a hydroelectric power plant, a factory, or the like. It is an object of the present invention to provide a small hydroelectric power generation system that is capable of effectively obtaining electric power energy by operating a water turbine / generator with high efficiency and is practical and useful.

FIG. 1 is an overall plan view of the system, and FIG. 3 is an overall front view of the system, FIG. 3 is an aa cross-sectional view of FIG. 1 (vertical side view of a secondary power generation system unit), and FIG. 4 is a bb cross-sectional view of FIG. ).
機械式小水力発電システムＫＳは、大略すると、原子力発電所、火力発電所、水力発電所、工場等の冷却水放水路（図示せず）内に配設され、同放水路を流れる水流（流水）Ｒを増速し、その増速した水流にてプロペラ水車を回転させて放水路内の水流Ｒの持つ運動エネルギーを水車の回転エネルギーに変換する一次動力源系ユニットＡと、この一次動力源系ユニットで得られた回転エネルギーを増幅して動力源として二次発電系ユニットの流速加速ポンプに伝達する動力源伝達手段Ｂと、この伝達された動力源にて駆動される流速加速ポンプにて、ポンプに送られてくる増速された放水路内の水流Ｒを更に加速・加圧せしめ、この更に加速・加圧されて運動エネルギーと圧力エネルギーとが増大された水流にて水車・発電機を回転し作動させて放水路内の水流Ｒの持つ運動エネルギーを効率良く有効に実用性、有用性に富む電力エネルギーに変換する二次発電系ユニットＣとを具備してなるものである。 The mechanical small hydroelectric power generation system KS is generally arranged in a cooling water discharge channel (not shown) of a nuclear power plant, a thermal power plant, a hydro power plant, a factory, etc. ) A primary power source system unit A that speeds up R, rotates the propeller turbine in the increased water flow, and converts the kinetic energy of the water flow R in the water discharge channel into the rotational energy of the water turbine, and the primary power source A power source transmission means B that amplifies the rotational energy obtained in the system unit and transmits it as a power source to the flow velocity acceleration pump of the secondary power generation system unit, and a flow velocity acceleration pump driven by the transmitted power source , Further accelerate and pressurize the water flow R in the spillway that is sent to the pump, and further accelerate and pressurize the water stream and the generator to increase the kinetic energy and pressure energy. Rotate and operate Efficiently effectively practical kinetic energy of water flow R in waterways release Te is made comprises a secondary power generating system unit C to be converted to electrical energy rich in usefulness.
一次動力源系ユニットＡは、先端部に開閉自在な制水ゲート１を有し放水路内を太い矢印方向に流れる水流（流水）Ｒを導入して増速するベンチュリー管構造の増流速水路２と、先端部がこの増流速水路２と接続し後端部が放水路へと繋がる排水路３と、この排水路３内に配設され増速された放水路内の水流にて回転してその水流Ｒの持つ運動エネルギーを回転エネルギーに変換して動力源となすプロペラ水車４とからなり、これら増流速水路２と排水路３とプロペラ水車４とは架台２０を介して放水路内に装備されるものである。 The primary power source system unit A has a water control gate 1 that can be freely opened and closed at the tip, and an increased flow velocity channel 2 having a venturi structure that introduces a water flow (flowing water) R that flows in the direction of the thick arrow in the discharge channel to increase the speed. And a drainage channel 3 whose front end is connected to the increased flow velocity channel 2 and whose rear end is connected to the discharge channel, and the water flow in the drainage channel which is disposed in the drainage channel 3 and is accelerated. It consists of a propeller turbine 4 that converts the kinetic energy of the water flow R into rotational energy and serves as a power source. These increased flow velocity channel 2, drainage channel 3, and propeller turbine 4 are installed in the drainage channel via the gantry 20. It is what is done.
ベンチュリー管構造の増流速水路２の入口（制水ゲート１側）と出口（水車４側）との断面積比は入口側４に対し出口側１に設定している。 従って、増流速水路２の入口と出口における水流の圧力差は入口側が高く出口側が低くなるが、水流の流速差は入口側が遅く出口側が速くなり、出口側（水車４側）では導入された水流Ｒの流速が約４倍に増速される。 The sectional area ratio between the inlet (water control gate 1 side) and the outlet (water turbine 4 side) of the increased flow velocity channel 2 of the venturi tube structure is set to the outlet side 1 with respect to the inlet side 4. Therefore, the pressure difference of the water flow at the inlet and outlet of the increased flow velocity channel 2 is higher on the inlet side and lower on the outlet side, but the flow velocity difference of the water flow is slower on the inlet side and faster on the outlet side, and the water flow introduced on the outlet side (water turbine 4 side). The flow rate of R is increased about 4 times.
増流速水路２にて増速された放水路内の水流Ｒは排水路３内に下掛け状態で配設されたプロペラ水車４に送られて同水車４を回転させて、放水路内を流れる水流Ｒの持つ運動エネルギーが水車４の回転エネルギーに変換され、後述する二次発電系ユニットＣにおける流速加速ポンプを回転駆動させる動力源が発生される。 The water flow R in the spillway that has been accelerated in the increased flow velocity channel 2 is sent to the propeller turbine 4 disposed in the drainage channel 3 in a suspended state, and the turbine 4 is rotated to flow in the spillway. The kinetic energy of the water flow R is converted into the rotational energy of the water turbine 4, and a power source for rotating the flow velocity acceleration pump in the secondary power generation system unit C described later is generated.
放水路の水流Ｒの運動エネルギーが水車４の回転エネルギーに変換されて得られた動力源は動力源伝達手段Ｂを介して増幅されて二次発電系ユニットＣにおける流速加速ポンプに伝達される。 ここではこの動力源伝達手段Ｂとしては、回転するプロペラ水車４の水車軸（回転軸）と流速加速ポンプのプロペラシャフト（回転軸）とを機械的に連繋接続した機械式伝達手段が用いられている。 The power source obtained by converting the kinetic energy of the water flow R in the discharge channel into the rotational energy of the water turbine 4 is amplified via the power source transmission means B and transmitted to the flow velocity acceleration pump in the secondary power generation system unit C. Here, as the power source transmission means B, mechanical transmission means is used in which the water wheel shaft (rotation shaft) of the rotating propeller turbine 4 and the propeller shaft (rotation shaft) of the flow velocity acceleration pump are mechanically connected. Yes.
即ち、この機械式伝達手段Ｂの具体的構造は次のとおりである。
制水ゲート１を開けて増流速水路２に導水され増速された放水路内の水流Ｒは、排水路３内に配設されたプロペラ水車４に送られて同水車４が回転する。水車４が回転するとその車軸（回転軸）５に取り付けられたフライホイール６が回転して水車４の回転速度が一定に安定し、回転エネルギーが回転動力として保有される。フライホイール６により水車４の回転速度が安定し回転エネルギーが回転動力として保有された時点で、クラッチ７が作動して増速機８に回転動力が伝達される。水車４の回転により得られた回転エネルギーは、回転動力として増速機８により増幅されて、連結シャフト９を介して二次発電系ユニットＣの流速加速ポンプのギアボックス１０に伝達されてそのギアーが回転し、更にその回転動力は連結シャフト１１を通じて流速加速ポンプのプロペラシャフトに伝達されて同ポンプが回転駆動される。
That is, the specific structure of the mechanical transmission means B is as follows.
The water flow R in the water discharge channel which has been guided to the increased flow velocity channel 2 by opening the water control gate 1 and increased in speed is sent to the propeller turbine 4 disposed in the drainage channel 3 to rotate the turbine wheel 4. When the water wheel 4 rotates, the flywheel 6 attached to the wheel shaft (rotating shaft) 5 rotates, the rotation speed of the water wheel 4 becomes constant and rotational energy is held as rotational power. When the rotational speed of the water turbine 4 is stabilized by the flywheel 6 and the rotational energy is held as rotational power, the clutch 7 is operated and the rotational power is transmitted to the speed increaser 8. The rotational energy obtained by the rotation of the water turbine 4 is amplified by the speed increaser 8 as rotational power, and is transmitted to the gear box 10 of the flow velocity acceleration pump of the secondary power generation system unit C via the connecting shaft 9 to be transmitted to the gear. Further, the rotational power is transmitted to the propeller shaft of the flow velocity acceleration pump through the connecting shaft 11, and the pump is driven to rotate.
二次発電系ユニットＣは、先端部に開閉自在な制水ゲート１２を有し放水路内の水流Ｒを導入して増速するベンチュリー管構造の増流速水路１３と、先端部がこの増流速水路１３に接続し後端部が放水路へと繋がる排水管１５に接続する導水管１４と、この導水管１４内に配設されて前記一次動力源系ユニットＡから伝達された動力源としての回転動力にて駆動され，増流速水路１３により送られ増速された放水路内の水流を更に加速・加圧する流速加速ポンプ１６と、この導水管１４と排水管１５との間に配設され，流速加速ポンプ１６にて更に加速・加圧された水流にて回転し作動して放水路内の水流Ｒの持つ運動エネルギーを電力エネルギーに変換する水車・発電機１７とからなり、これらは架台１８を介して放水路内に装備されるものである。 The secondary power generation system unit C has a water control gate 12 that can be freely opened and closed at the front end portion, and an increased flow velocity water passage 13 having a venturi structure that introduces a water flow R in the water discharge passage to increase speed, and the front end portion has this increased flow velocity. A water conduit 14 connected to a water channel 13 and connected to a drain pipe 15 whose rear end is connected to a water discharge channel, and a power source disposed in the water conduit 14 and transmitted from the primary power source system unit A A flow speed acceleration pump 16 that is driven by rotational power and is further accelerated and pressurized by the water flow in the water discharge path that has been sent and increased by the flow speed increasing water channel 13 and disposed between the water conduit 14 and the drain pipe 15. , And a turbine / generator 17 that rotates and operates in a water flow further accelerated and pressurized by the flow velocity acceleration pump 16 and converts the kinetic energy of the water flow R in the water discharge channel into electric energy, and these are the gantry It is equipped in the spillway through 18 It is.
二次発電系ユニットＣにおいても、一次動力源系ユニットＡにおける場合と同様に、放水路内の水流Ｒは先ず始めにベンチュリー管構造の増流速水路１３に導入されてその流速が増速される。即ち、同じくベンチュリー管構造の増流速水路１３の入口（制水ゲート１２側）と出口（流速加速ポンプ１６側）との断面積比は入口側４に対し出口側１に設定されている。 従って、増流速水路１３の入口と出口における水流Ｒの圧力差は入口側が高く出口側が低くなるが、水流の流速差は入口側が遅く出口側が速くなり、出口側（流速加速ポンプ１６側）では導入された水流Ｒの流速が約４倍に増速されて流速加速ポンプ１６に送られる。 Also in the secondary power generation system unit C, as in the case of the primary power source system unit A, the water flow R in the discharge channel is first introduced into the increased flow velocity channel 13 of the Venturi tube structure and the flow velocity is increased. . That is, the sectional area ratio between the inlet (water control gate 12 side) and the outlet (flow velocity acceleration pump 16 side) of the increased flow velocity water channel 13 having the same venturi structure is set to the outlet side 1 with respect to the inlet side 4. Therefore, the pressure difference of the water flow R at the inlet and outlet of the increased flow velocity channel 13 is higher on the inlet side and lower on the outlet side, but the flow velocity difference of the water flow is slower on the inlet side and faster on the outlet side, and is introduced on the outlet side (flow velocity acceleration pump 16 side). The flow velocity of the water stream R is increased by about four times and sent to the flow velocity acceleration pump 16.
流速加速ポンプ１６のプロペラシャフトには、一次動力源系ユニットＡで得られた水車４の回転エネルギーが回転動力として動力源伝達手段Ｂを介して増幅されて伝達され、これによって流速加速ポンプ１６が回転駆動される。従って二次発電系ユニットＣにおいては、増流速水路１３により増速された放水路の水流Ｒが流速加速ポンプ１６の回転駆動によって更に増速・加圧されて導水管１４を通して水車・発電機１７に送られ同水車・発電機１７が回転される。 従って流速加速ポンプ１６の回転駆動によって、増速された放水路の水流Ｒが持つ運動エネルギーと圧力エネルギーとが更に増大されて水車・発電機１７に送られる、即ちこれによって水車・発電機１７を回転させようとする水流Ｒのエネルギーが遥かに増大されて同水車・発電機１７に送られるので、より実用性、有用性に富む電力エネルギーに効率良く変換される。 水車・発電機１７の回転により発生した電力は一次側送電ケーブル、二次変電設備、二次側送電ケーブルを経由して需要家に安定して供給される。 水車・発電機１７を回転させた水流Ｒは排水管１５を通り放水路に放水される。 The rotational energy of the water turbine 4 obtained by the primary power source system unit A is amplified and transmitted as rotational power via the power source transmission means B to the propeller shaft of the flow velocity acceleration pump 16, whereby the flow velocity acceleration pump 16 is Driven by rotation. Therefore, in the secondary power generation system unit C, the water flow R in the discharge channel accelerated by the increased flow velocity channel 13 is further increased and pressurized by the rotational drive of the flow velocity acceleration pump 16, and the water turbine / generator 17 is passed through the water conduit 14. The water turbine / generator 17 is rotated. Accordingly, the kinetic energy and pressure energy of the increased water flow R in the discharge channel are further increased by the rotational drive of the flow velocity acceleration pump 16 and are sent to the water turbine / generator 17. Since the energy of the water stream R to be rotated is greatly increased and sent to the water turbine / generator 17, it is efficiently converted into electric energy more practical and useful. The electric power generated by the rotation of the water turbine / generator 17 is stably supplied to the customer via the primary side transmission cable, the secondary substation facility, and the secondary side transmission cable. The water flow R obtained by rotating the water turbine / generator 17 passes through the drain pipe 15 and is discharged into the water discharge channel.
図１〜図４においては、一次動力源系ユニットＡのプロペラ水車４の回転軸（車軸）５の左右両側に二次発電系ユニットＣの流速加速ポンプ１６の回転軸を夫々動力源伝達手段Ｂを介して連繋接続せしめたものが示されている。即ちこの場合には、回転動力（動力源）発生用の一次系プロペラ水車４一基で水車の回転エネルギー増大用の流速加速ポンプ１６を介して二基の発電用水車・発電機１７を連動稼動させて電力を得ることができ効率的である。 1 to 4, the rotational shafts of the flow velocity acceleration pump 16 of the secondary power generation system unit C are respectively connected to the left and right sides of the rotational shaft (axle) 5 of the propeller turbine 4 of the primary power source system unit A. It is shown that they are connected to each other via the line. That is, in this case, two primary turbines 4 for generating rotational power (power source) are operated in conjunction with two turbines / generators 17 for generating power via a flow velocity acceleration pump 16 for increasing rotational energy of the turbine. It is possible to obtain electric power and is efficient.
二次発電系ユニットＣにおける流速加速ポンプ１６の配設はベンチュリー管構造の増流速水路１３と水車・発電機１７を配設した導水管１４との間に水中カプセル装置１９を介在させて行う。この水中カプセル装置１９は、カプセル内に制水ゲート１２を有する増流速水路１３に接続するカプセル内導水管前端部１９ａと水車・発電機１７を配設した導水管１４と接続し制水ゲート（図示せず）を設けたカプセル内導水管後端部１９ｃとその前後両端部の導水管の中間部を繋ぐカプセル内導水管中間部１９ｂとを設け、このカプセル内導水管中間部１９ｂは、内部に流速加速ポンプ１６を有しないものと内部に流速加速ポンプ１６を組み込んだものとを接続切り替え自在となして使用するものである． このカプセル内導水管中間部１９ｂの接続切り替えによって、架台１８の設置作業を放水路内を流れる水流Ｒの流れを止めることなくその流水抵抗と浮力抵抗を軽減させて円滑に行うができる。また流速加速ポンプ１６と増流速水路１３のメンテナンス時に架台１８を移動することなくそのメンテナンス作業を円滑に行うことができ好適である。 In the secondary power generation system unit C, the flow velocity acceleration pump 16 is disposed by interposing an underwater capsule device 19 between the increased flow velocity water channel 13 having a venturi tube structure and the water guide tube 14 in which the water turbine / generator 17 is disposed. This underwater capsule device 19 is connected to a water guide pipe 14 provided with a water turbine / generator 17 connected to a capsule water guide pipe front end 19a connected to an increased flow velocity channel 13 having a water control gate 12 in the capsule. The capsule water guide pipe rear end portion 19c provided with a not-shown capsule inner guide pipe intermediate portion 19b connecting the middle portions of the water guide pipes at both front and rear ends thereof is provided. The one having no flow velocity acceleration pump 16 and the one having the flow velocity acceleration pump 16 incorporated therein can be connected and switched. By switching the connection of the in-capsule conduit pipe intermediate portion 19b, the installation work of the gantry 18 can be smoothly performed without reducing the flow resistance and buoyancy resistance without stopping the flow of the water flow R flowing through the water discharge channel. Further, it is preferable that the maintenance work can be smoothly performed without moving the gantry 18 during the maintenance of the flow velocity acceleration pump 16 and the increased flow velocity water channel 13.
一次動力源系ユニットＡにおける増流速水路２と排水路３とプロペラ水車４ならびに二次発電系ユニットＣにおける増流速水路１３と導水管１４と排水管１５と流速加速ポンプ１６と水車・発電機１７の放水路内への配設は、同放水路内の配設位置の水面が潮位の変化の影響を受ける位置にあるか否かに応じて、放水路内の川床に固定された固定架台と、川床に固定されず固定架台に係留チェーン等で連結されて水面上に浮設される浮体架台とに適宜使い分けて夫々の架台に装備せしめて行う。 即ち、火力発電所などの放水路は、通常の場合海に接続されていて、放水路の一部は常に潮位の変動が起きていると考えられる。そこで、固定架台は水面の変化が少ない場所に設置し、浮体架台は潮流などの影響を受け、潮の干満による水面の変化が大きい場所に設置する。 浮体架台を設置する場合には、現場で設備艤装後クレーンで吊り、固定架台、及び係留杭に係留チェーンを連結後、水面に設置する。そして水面に設置後、バラストタンクに水を張り、所定のトリムに修正する。 図１〜図４においては、水面に浮設する浮体架台２０、１８を用いて装備する例を示しており、同装備の配設位置の水面が海側と遠い上流にある場合には放水路の川床に前以て施工した基礎杭に固定架台を取り付け固定して行う。 Increased velocity water channel 2, drainage channel 3, propeller turbine 4 in primary power source system unit A and increased velocity water channel 13, water guide pipe 14, drainage pipe 15, flow velocity acceleration pump 16, turbine / generator 17 in secondary power generation system unit C Depending on whether the water surface at the installation location in the discharge channel is in a position that is affected by changes in the tide level, a fixed gantry fixed to the river bed in the discharge channel can be used. This is done by properly using a floating frame that is not fixed to the riverbed but is connected to a fixed frame with a mooring chain and floats on the surface of the water. That is, it is considered that the spillway such as a thermal power plant is normally connected to the sea, and a part of the spillway is constantly changing in tide level. Therefore, the fixed base is installed in a place where there is little change in the water surface, and the floating base is installed in a place where the change in the water surface due to tidal currents is large due to the influence of the tide. When installing a floating frame, suspend it with a crane after installing equipment on the site, connect a fixed frame and a mooring chain to a mooring pile, and then install it on the water surface. After installation on the water surface, the ballast tank is filled with water and corrected to a predetermined trim. 1 to 4 show an example in which the equipment is installed using the floating bases 20 and 18 floating on the water surface, and when the water surface at the installation position of the equipment is upstream from the sea side, the water discharge channel. A fixed base is attached and fixed to the foundation pile previously constructed on the riverbed.
ちなみに一次動力源系ユニットＡにおいては、放水路を流れる0.5〜1.0ｍ／ｓ程度の水流Ｒの流速を固定架台と浮体架台とに使い分けて装着された増流速水路２でおよそ3〜3.5ｍ／ｓ程度まで増速してプロペラ水車４に送り動力源としての回転エネルギーを発生させる。
この発生した回転エネルギーは、動力源伝達手段Ｂにおける増速機８等により増速（増幅）されて、動力源として二次発電系ユニットＣの流速加速ポンプ１６に伝達される。
二次発電系ユニットＣにおいては、一次動力源系ユニットＡと同様に放水路を流れる水流Ｒの流速を増流速水路１３にておよそ3〜3.5ｍ／ｓ程度まで増速し、流速加速ポンプ１６に送る。流速加速ポンプ１６は一次動力源系ユニットＡより伝達された回転エネルギーで回転駆動し、増流速水路１３で増速された水流を更におよそ10〜15ｍ／ｓまで加速・加圧して、水流の運動エネルギーと圧力エネルギーを一層増大させて発電用の水車・発電機１７に送る。水車・発電機１７は流速加速ポンプ１６より送られた増大された回転エネルギーにより回転して、電力エネルギーを発生させる。
By the way, in the primary power source system unit A, the flow velocity R of the water flow R of about 0.5 to 1.0 m / s flowing through the discharge channel is about 3 to 3.5 m / s in the increased flow rate channel 2 that is installed separately for the fixed frame and the floating frame. The speed is increased to about s, and the propeller turbine 4 is fed with rotational energy as a power source.
