Description
本発明は、油或いは空気など流体或いは気体を媒体とする装置の応用技術に関する。 The present invention relates to an application technique of a device using a fluid or gas such as oil or air as a medium.
水資源を利用する発電装置において、立坑状の昇降路とロープで接続され水を収容/排水できる昇降籠とを夫々2組備えて、当該昇降籠への給排水を適時制御して上下動を継続させ、その位置エネルギーから電力を得る構造が知られている。(例えば、特許文献1参照) In power generation equipment that uses water resources, two sets of hoisting pits that are connected to a shaft-like hoistway and are connected to each other to accommodate / drain water are provided. And a structure for obtaining electric power from the potential energy is known. (For example, see Patent Document 1)
このような自然エネルギーを利用する発電装置は、地球環境に優しい発電手段として周知されているが、気象条件に影響されない安定した発電出力を得るには、前記昇降籠が位置エネルギーに比例する相当の高さと質量で自由落下した際の衝撃力緩和と、更に発電に供した水資源を再利用することが不可欠である。
位置エネルギーに比例する相当の高さと質量の昇降籠であっても、自由落下した際の衝撃を緩和する装置を提供する。 Provided is a device that reduces the impact of a free fall even if the height and mass of the lift are proportional to the potential energy.
本発明は、立坑状の昇降路下部に具備する衝撃吸収構造物と、それに包含する可動隔壁の所定動作を補完する装置に関する。 The present invention relates to an impact absorbing structure provided at a lower part of a shaft-like hoistway and an apparatus for complementing a predetermined operation of a movable partition wall included therein.
下部に水を貯水する昇降路と昇降籠とを夫々2組有する構造物において、当該貯水した水の水面下で当該昇降路を隔てる可動隔壁と当該可動隔壁内に開閉を制御できる開閉口と、当該昇降路の当該可動隔壁よりも下部と貯水槽とを連絡する複数の導水管と、個々の当該導水管の開閉を制御するバルブ及び逆止弁あるいは逆止弁が一体となったバルブから成る衝撃吸収構造物を夫々の当該昇降路内に備えることを特徴とする水力発電装置が発明されている。(特許文献2参照) In a structure having two sets of hoistway and hoisting basin for storing water in the lower part, a movable partition wall that separates the hoistway under the surface of the stored water, and an opening and closing port that can control opening and closing in the movable partition wall, It consists of a plurality of conduit pipes connecting the lower part of the hoistway with the movable partition wall and the water storage tank, a valve for controlling opening and closing of the individual conduit pipes, and a check valve or a valve integrated with the check valve. There has been invented a hydroelectric generator characterized in that an impact absorbing structure is provided in each hoistway. (See Patent Document 2)
前記衝撃吸収構造物は、昇降籠が自由落下した際の衝撃力を昇降路と隔てた可動隔壁下の貯水を介在させて、複数の導水管の直列経路に設けたバルブを順次開閉して流量を順次制限することで、衝撃吸収と水等媒体の一部を当該昇降路上方の貯水槽に揚水する機能を有している。 The shock absorbing structure is configured to sequentially open and close valves provided in a series path of a plurality of water conduits by interposing a water storage under a movable partition wall that separates the hoistway from the impact force when the hoist is freely dropped. By sequentially limiting the above, there is a function of absorbing impact and pumping a part of the medium such as water to the water storage tank above the hoistway.
相似する2組の前記昇降籠が安定して所定の上下動を継続するには、上下動のサイクル毎に当該昇降籠内に収容した相当分の水資源を、前記昇降路上方の貯水槽に揚水するか或いは外部へ排水する。このとき、前記衝撃吸収構造物内に包含する可動隔壁が、所定の上下限に交互に到達することで安定した上下動が可能である。
In order for two similar sets of hoisting rods to stably continue predetermined vertical movements, a considerable amount of water resources stored in the hoisting rods are stored in the water storage tank above the hoistway in each vertical movement cycle. Pump up or drain to the outside. At this time, the movable partition included in the shock absorbing structure can reach a predetermined upper and lower limit alternately, thereby enabling stable vertical movement.
前記可動隔壁は、残留する媒体を揚水ポンプ等により揚水するか或いは外部へ排出することで下限へ移動するが、上限へは、当該可動隔壁を支持する構造物中のショックアブソーバの蓄圧による反発力に期待している。しかしながら当該ショックアブソーバの蓄圧だけに頼れば、損失等により蓄圧が失われたとき上限への移動が確実にできない。 The movable partition moves to the lower limit by pumping the remaining medium with a pump or the like or discharges it to the outside, but the upper limit is the repulsive force due to the pressure accumulation of the shock absorber in the structure that supports the movable partition I am looking forward to it. However, if only the pressure accumulation of the shock absorber is relied upon, it cannot be surely moved to the upper limit when the pressure accumulation is lost due to loss or the like.
前記ショックアブソーバを、油或いは空気など流体或いは気体を媒体とするシリンダに替えて、その一端を夫々の当該可動隔壁に接続し、夫々の当該シリンダ間の媒体経路を開閉制御できるバルブ1と、当該シリンダにタンク及びポンプから媒体を供給及び排出する開閉制御できるバルブ2とを備える支持構造物にする。
The shock absorber is replaced with a cylinder using a fluid or gas medium such as oil or air, one end of which is connected to each movable partition wall, and a valve 1 capable of controlling the opening and closing of the medium path between the cylinders, A support structure including a cylinder 2 and a valve 2 that can be controlled to be opened and closed to supply and discharge a medium from a tank and a pump.
前記昇降籠が下降して当該可動隔壁に到達する直前、前記バルブ1を"開"に制御すると押圧されている当該可動隔壁を支持するシリンダは下降して当該シリンダ内の媒体を、他方のシリンダへ供給し支持している可動隔壁の上方への移動を強制する。
何れの手段でも当該昇降籠が減速している下限近傍では、当該可動隔壁を押圧する衝撃力は微弱になるのは明らかで、前記バルブ2のポンプから当該シリンダへ媒体を供給する経路、或いはタンクへ媒体を排出する経路を"開"にすることで、当該可動隔壁の上限或いは下限への移動を強制できる。
付随して、当該両シリンダ内の媒体を均衡して増減できるので、当該可動隔壁の所定移動ストロークを可変できる。
Immediately before the elevating rod descends and reaches the movable partition, the cylinder that supports the movable partition that is pressed when the valve 1 is controlled to open is lowered so that the medium in the cylinder is transferred to the other cylinder. Force the upward movement of the movable partition that is supplied to and supported by.
It is clear that the impact force that presses the movable partition wall is weak in the vicinity of the lower limit at which the lifting / lowering rod decelerates by any means, and the path or tank for supplying the medium from the pump of the valve 2 to the cylinder By opening the path for discharging the medium to “open”, the movable partition can be forced to move to the upper limit or the lower limit.
Along with this, the media in both cylinders can be balanced and increased, so that the predetermined movement stroke of the movable partition can be varied.
複数の導水管の開閉制御により衝撃力を緩和するには、上部貯水槽に連絡する当該導水管全体の管径を、昇降籠の降下速度が最大になる可動隔壁に到達した瞬時、当該可動隔壁下の貯水を揚水或いは排水する流量を制限しない位に、また当該上部貯水槽にいたる上端まで一様に同じにする必要がある。結果として、当該導水管内全体には揚水する必要の無いものも含めて貯水される。 To alleviate the impact force by controlling the opening and closing of a plurality of conduits, the diameter of the entire conduit connected to the upper water storage tank is instantly reached when it reaches the movable partition where the descending speed of the lifting hoist is maximized. It is necessary to make the same amount up to the upper end leading to the upper water tank so as not to limit the flow rate of pumping or draining the lower water storage. As a result, water is stored in the entire conduit, including those that need not be pumped.
昇降籠に収容する相当分以上を揚水する必要は無く、そのため前記上部貯水槽に連絡する導水管1とは別に、当該可動隔壁下に貯水する緩衝ストローク相当分を一時収容する複数の導水管2を当該昇降路下部に具備する。当該導水管2夫々の下端は開閉制御できるバルブを介して当該可動隔壁下の下部貯水槽に、上端は当該昇降路別に備える圧力調整室に連絡する。当該導水管2の実揚程は前記緩衝ストローク相当でよいため、前記導水管1のみの場合と比較して揚水のための負荷を著しく軽減できる。
ここで当該緩衝ストローク相当分の貯水量は、当該導水管を時系列で順次閉じる時間即ち減速時間を加味した量に設定する。
It is not necessary to pump more than the equivalent amount accommodated in the elevating rod, and therefore, a plurality of conduits 2 that temporarily accommodate the equivalent portion of the buffer stroke that stores water under the movable bulkhead separately from the conduit 1 that communicates with the upper reservoir. At the bottom of the hoistway. The lower end of each of the water conduits 2 is connected to a lower water storage tank below the movable partition wall via a valve that can be controlled to be opened and closed, and the upper end is connected to a pressure adjusting chamber provided for each hoistway. Since the actual head of the water conduit 2 may be equivalent to the buffer stroke, the load for pumping can be significantly reduced as compared with the case of the water conduit 1 alone.
Here, the water storage amount corresponding to the buffer stroke is set to an amount that takes into account the time for sequentially closing the water conduit in time series, that is, the deceleration time.
昇降籠が自由落下して可動隔壁に到達した以降、当該可動隔壁下に貯水した緩衝ストローク相当分を前記導水管2に直列経路にあるバルブを順次閉じて、当該可動隔壁を減速させながら収容した次に、当該昇降籠に収容した相当分を前記導水管1により前記上部貯水槽へ揚水する。
当該昇降籠が減速している下限近傍で当該可動隔壁を押圧する衝撃力は微弱なので、前記緩衝ストローク相当分を当該導水管2に全部収容する前に、前記バルブを一旦閉じて前記上部貯水槽に揚水した後、再度、前記バルブを開けて残量を収容する運用では、衝撃力が微弱になる前なのでより効果的に前記上部貯水槽へ揚水できる。
After the elevating rod freely falls and reaches the movable partition, the buffer stroke corresponding to the water stored under the movable partition is accommodated while the movable partition is decelerated by sequentially closing the valves in the series path to the conduit 2. Next, the equivalent portion accommodated in the lifting / lowering trough is pumped to the upper water storage tank by the water conduit 1.
The impact force that presses the movable partition wall in the vicinity of the lower limit at which the lifting / lowering rod is decelerating is weak. Therefore, before the buffer stroke is fully accommodated in the water conduit 2, the valve is temporarily closed and the upper water storage tank In the operation of opening the valve again and storing the remaining amount after pumping up the water, the impact can be pumped to the upper water tank more effectively because the impact force is not weak.
可動隔壁の側面と昇降路の内壁とは気密を密にしており、当該可動隔壁に備える開閉制御できる開閉口を閉じているとき、当該可動隔壁下の貯水は当該昇降路へ容易に流出しない。当該可動隔壁の支持に前述した支持構造物を適用したとき、昇降籠で押圧されて下降する当該可動隔壁の他方は相対して上昇する。この上昇するタイミングで、前記導水管2の直列経路にあるバルブを全て開くと、当該可動隔壁下は圧力を保持しているため当該導水管2に貯水している前記緩衝ストローク相当分を当該可動隔壁下に充当する。
昇降路別に備える圧力調整室は、前記導水管2内に貯水する際は、内封する空気等の媒体が圧縮され圧力が高くなることで当該可動隔壁の減速性能を補助し、反転して当該導水管2内の貯水を排出する際は、圧縮された高い圧力で当該可動隔壁下への充当を補助する。
The side surface of the movable partition wall and the inner wall of the hoistway are hermetically sealed, and when the opening / closing port that can be controlled to open and close is closed, the water stored under the movable partition wall does not easily flow into the hoistway. When the above-described support structure is applied to the support of the movable partition, the other of the movable partitions that are pressed and lowered by the elevating rod rises relatively. When all the valves in the series path of the water conduit 2 are opened at this rising timing, the pressure below the movable partition is maintained, so that the amount corresponding to the buffer stroke stored in the water conduit 2 is movable. Appropriate under the bulkhead.
The pressure adjusting chamber provided for each hoistway assists the speed reduction performance of the movable partition wall by compressing the medium such as air to be compressed and increasing the pressure when storing the water in the water conduit 2, and reverses the pressure control chamber. When draining the water stored in the water conduit 2, the application of the compressed high pressure assists the application under the movable partition wall.
立坑状の昇降路とロープで接続され水を収容/排水できる昇降籠と、当該昇降路内の下部に可動隔壁とを夫々2組備えて、当該昇降籠への給排水を適時制御して上下動を継続する装置において、前述した衝撃吸収構造物と併せて包含する可動隔壁の支持構造物を適用したとき、自由落下した際の衝撃緩和と当該昇降籠に収容した一部を上部の貯水槽に揚水することが可能で、発電手段は、例えば機械的に結合しているプーリ軸に連絡する発電タービンから電力を得ることが可能である。
昇降籠の上下限の移動ストロークで一意的に決まる周期でエネルギー密度は脈動するが、当該昇降籠への給排水で始動及び停止を任意タイミングで制御できるため、位相を変えて複数の同規模装置を運転することでエネルギー密度を平準化に近づけることができる。
Two sets of hoisting pits that can be connected to the shaft-like hoistway with ropes to store / drain water, and two movable partitions at the lower part of the hoistway, and control the water supply / drainage to the hoisting hoist to move up and down In the device that continues the above, when the support structure of the movable partition wall that is included together with the shock absorbing structure described above is applied, the impact is alleviated when it falls freely and a part accommodated in the lifting rod is stored in the upper reservoir. Water can be pumped and the power generation means can obtain power from, for example, a power generation turbine connected to a mechanically coupled pulley shaft.
Although the energy density pulsates with a cycle uniquely determined by the upper and lower limit movement strokes of the lifting / lowering hoist, it is possible to control starting and stopping at any timing by supplying and draining to the hoisting / lowering hoist, so multiple devices of the same scale can be changed by changing the phase. By operating, the energy density can be brought close to leveling.
揚水ポンプのように作用するため、昇降籠の上下動に使用した水等媒体の装置外部への排出を最小限にできる。
Since it acts like a pump, it is possible to minimize the discharge of the medium such as water used for the vertical movement of the lifting rod to the outside of the device.
立坑状の昇降路とロープで接続され水を収容/排水できる昇降籠と、当該昇降路の下部に可動隔壁を包含する衝撃吸収構造物とを夫々2組備えて、当該昇降籠への給排水を適時制御して上下動を継続させて、目的の位置エネルギーから電力を得る構造物において、相似する昇降籠が交互に上下間移動できるように補完する装置である。 Two sets of hoisting rods that are connected to a shaft-like hoistway by a rope and can accommodate / drain water, and two shock absorbing structures including a movable partition wall at the lower part of the hoisting channel are provided to supply and drain water to the hoisting shaft. It is a device that complements so that similar lifting rods can move up and down alternately in a structure that obtains electric power from the target potential energy by continuing vertical movement by controlling timely.
図1に本発明に係る第一実施形態の可動隔壁の支持構造物の斜視図を示す。
図より可動隔壁10を支持する油圧シリンダ11aから11dと支持台12aから12d、及び可動隔壁20を支持する油圧シリンダ21aから21dと支持台22aから22dは、図示していない夫々独立した立坑内の昇降路下部に設置され、相似する昇降籠が当該可動隔壁を交互に押し下げる。
油圧シリンダ11aから11dと油圧シリンダ21aから21dの油経路は、パイプ40を介してバルブ30により開閉制御できる。更に油圧シリンダ11aから11dは開閉制御できるバルブ31を介して、油圧シリンダ21aから21dは開閉制御できるバルブ32を介して、図示していない油タンクと油圧ポンプに夫々導管41aと41b及び導管42aと42bを介して接続している。
FIG. 1 is a perspective view of a movable partition support structure according to the first embodiment of the present invention.
From the figure, the hydraulic cylinders 11a to 11d and the support bases 12a to 12d for supporting the movable partition wall 10 and the hydraulic cylinders 21a to 21d and the support bases 22a to 22d for supporting the movable partition wall 20 are respectively shown in independent shafts not shown. A similar lifting rod installed at the lower part of the hoistway alternately pushes down the movable bulkhead.
The oil paths of the hydraulic cylinders 11 a to 11 d and the hydraulic cylinders 21 a to 21 d can be controlled to open and close by the valve 30 via the pipe 40. Further, the hydraulic cylinders 11a to 11d are connected to an oil tank and a hydraulic pump (not shown) through conduits 41a and 41b and a conduit 42a through a valve 31 that can be controlled to open and close, and hydraulic valves 21a to 21d through a valve 32 that can be controlled to open and close. 42b is connected.
図2に図1に係る油圧回路図を示す。
図より油圧シリンダ11aから11dは同じ動作をするので油圧シリンダ11に、同様に油圧シリンダ21aから21dは油圧シリンダ21にモデル化している。
図示していない昇降籠が下降して可動隔壁10(又は20)を押し下げると、バルブ30の電磁ソレノイドSOL1とバルブ35の電磁ソレノイドSOLを励磁しているとき、油圧シリンダ11(又は21)内下部から他方の油圧シリンダ内下部へ、油圧シリンダ21(又は11)内上部から他方の油圧シリンダ内上部に油が移動して可動隔壁20(又は10)は上昇する。バルブ30の電磁ソレノイドSOL2に励磁を切り換えることで、油経路中の流量調整弁57で流量を制限して当該可動隔壁の下降/上昇速度を制限する。ここで逆止弁53と54及び逆止弁58と60は、油圧シリンダ11と21から油圧ポンプ51への逆流を防止する。
FIG. 2 shows a hydraulic circuit diagram according to FIG.
Since the hydraulic cylinders 11a to 11d perform the same operation, the hydraulic cylinders 11a to 21d are modeled as the hydraulic cylinder 21.
When an elevating rod (not shown) descends and pushes down the movable partition wall 10 (or 20), when the electromagnetic solenoid SOL1 of the valve 30 and the electromagnetic solenoid SOL of the valve 35 are energized, the lower part in the hydraulic cylinder 11 (or 21) From the upper part in the hydraulic cylinder 21 (or 11) to the lower part in the other hydraulic cylinder, the oil moves from the upper part in the other hydraulic cylinder to the movable partition 20 (or 10). By switching the excitation to the electromagnetic solenoid SOL2 of the valve 30, the flow rate is limited by the flow rate adjusting valve 57 in the oil path to limit the descending / raising speed of the movable partition wall. Here, the check valves 53 and 54 and the check valves 58 and 60 prevent the backflow from the hydraulic cylinders 11 and 21 to the hydraulic pump 51.
昇降籠が減速して可動隔壁10(又は20)が下限に到達しないとき、バルブ30と35の電磁ソレノイドはいずれも励磁オフにし、バルブ36(又は37)の電磁ソレノイドSOL2を励磁して、油圧シリンダ11(又は21)内上部に逆止弁59(又は61)を介して油圧ポンプ51から油を供給するのと、同時にバルブ31(又は32)の電磁ソレノイドSOL1を励磁して、当該シリンダ内下部から同量を油タンク50に排出する。
他方の可動隔壁20(又は10)の上限位置を保障するために、バルブ32(又は31)の電磁ソレノイドSOL2を励磁して、油圧シリンダ21(又は11)内下部に逆止弁付き流量調整弁56(又は55)を介して油を供給するのと、同時にバルブ39(又は38)の電磁ソレノイドSOLとバルブ37(又は36)の電磁ソレノイドSOL1を励磁して、当該シリンダ内上部から同量を油タンク50に排出する。
当該可動隔壁の移動速度はバルブ33(又は34)の電磁ソレノイドSOLを励磁したときは速やかに、励磁しないときは逆止弁付き流量調整弁55(又は56)で流量を制限する低速に制御できる。このように可動隔壁10と20の下限及び上限への移動を確実にできる。
When the elevating / lowering rod decelerates and the movable bulkhead 10 (or 20) does not reach the lower limit, both the solenoids of the valves 30 and 35 are turned off, and the electromagnetic solenoid SOL2 of the valve 36 (or 37) is excited to hydraulically When oil is supplied from the hydraulic pump 51 to the upper part of the cylinder 11 (or 21) via the check valve 59 (or 61), the electromagnetic solenoid SOL1 of the valve 31 (or 32) is excited at the same time, The same amount is discharged from the lower part to the oil tank 50.
In order to ensure the upper limit position of the other movable partition wall 20 (or 10), the electromagnetic solenoid SOL2 of the valve 32 (or 31) is excited, and a flow rate adjusting valve with a check valve is provided in the lower part of the hydraulic cylinder 21 (or 11). When the oil is supplied through 56 (or 55), the electromagnetic solenoid SOL of the valve 39 (or 38) and the electromagnetic solenoid SOL1 of the valve 37 (or 36) are excited simultaneously, and the same amount is supplied from the upper part in the cylinder. Discharge into the oil tank 50.
The moving speed of the movable partition can be controlled quickly when the electromagnetic solenoid SOL of the valve 33 (or 34) is energized, and at a low speed that restricts the flow rate with the non-excited flow rate adjusting valve 55 (or 56). . Thus, the movement to the minimum and the upper limit of the movable partition walls 10 and 20 can be ensured.
可動隔壁10及び20の上限は、油圧シリンダ11及び12内の油量を増減することで設定する。これより当該可動隔壁の上下限の移動ストロークは、当該油圧シリンダのロッドの可動範囲内で任意に設定できる。 The upper limit of the movable partition walls 10 and 20 is set by increasing or decreasing the amount of oil in the hydraulic cylinders 11 and 12. Accordingly, the upper and lower limit movement strokes of the movable partition can be arbitrarily set within the movable range of the rod of the hydraulic cylinder.
図3から図6に本発明に係る水力発電装置の第一実施形態の構造と、動作を説明する状態還移を順に示す。図3から図6共通に、上部貯水槽110の配水口扉102aと102bを開閉制御して、昇降路100a上部の配水口101aと、昇降路100b上部の配水口101bから昇降籠120aと120b夫々に給水できる。昇降籠120aと120bはロープ104で夫々の上端に接続され、上部に取水口と下部に排水口を夫々開閉制御できる開閉口を有して、交互に水収容と排水を繰り返すと当該昇降路内を交互に上下動を継続する。
又、可動隔壁10及び20の側面と当該昇降路の内壁とは気密を密にしており、当該可動隔壁に備える開閉制御できる開閉口を閉じているとき、当該可動隔壁下の貯水は当該昇降路へ容易に流出しない。
FIG. 3 to FIG. 6 sequentially show the structure of the first embodiment of the hydroelectric generator according to the present invention and the state return for explaining the operation. 3 to 6, the opening and closing control of the water distribution doors 102 a and 102 b of the upper water storage tank 110 is performed, so that the water distribution ports 101 a at the upper part of the hoistway 100 a and the hoistway 120 a and 120 b from the water distribution port 101 b at the upper part of the hoistway 100 b are respectively provided. Can supply water.

The large diameter pipe 40 communicates with the valve 30.
可動隔壁10と20下に下部貯水槽111aと111bを有し、当該下部貯水槽から上部貯水槽110に導水管131aから131dにより、直列経路に開閉制御できるバルブ141aから141dと、当該下部貯水槽への逆流を防止する逆止弁142aから142dを介して連絡している。当該導水管131aと131b及び131cと131dの総容積は前記昇降籠の収容相当量としている。
導水管132aと132b及び導水管133aと133bにより、直列経路に開閉制御できるバルブ143aから143cを介して、上部貯水槽110から当該可動隔壁の上或いは下に給水する量を調整できる。又、導水管134aと134b及び直列経路に開閉制御できるバルブ144aと144bを介して、当該下部貯水槽内の水を装置外部に排水できる。
Valves 141a to 141d that have lower reservoirs 111a and 111b below the movable partition walls 10 and 20, and that can be controlled to open and close in a serial path from the lower reservoir to the upper reservoir 110 by conduits 131a to 131d, and the lower reservoir Communication is made via check valves 142a to 142d which prevent backflow into the valve. The total volume of the water guide pipes 131a and 131b and 131c and 131d is set to an amount corresponding to the accommodation of the lifting / lowering rod.
By the water conduits 132a and 132b and the water conduits 133a and 133b, the amount of water supplied from the upper water storage tank 110 to above or below the movable partition wall can be adjusted via valves 143a to 143c that can be controlled to open and close in series. Further, the water in the lower water storage tank can be drained to the outside of the apparatus through the water conduits 134a and 134b and the valves 144a and 144b that can be controlled to open and close in series.
可動隔壁10下の緩衝ストローク相当分を含む下部貯水槽111aの貯水は、開閉制御できるバルブ140aから140jを介して導水管130aから130jに、当該可動隔壁が押圧され下降したとき当該緩衝ストローク相当分を貯水する。同様に、開閉制御できるバルブ140kから140tを介して導水管130kから130tに、可動隔壁20が押圧され下降したとき当該可動隔壁下の緩衝ストローク相当分を貯水する。
圧力調整室112aと112bは空気などを内封して密閉しており、当該導水管内に緩衝ストローク相当分が収容されると加圧され、反転して排出するときには当該可動隔壁下への充当を補助する。
The water stored in the lower water tank 111a including the equivalent of the buffer stroke under the movable partition 10 is equivalent to the buffer stroke when the movable partition is pressed and lowered to the water conduits 130a to 130j via the valves 140a to 140j that can be controlled to open and close. To store water. Similarly, when the movable partition 20 is pressed and lowered from the conduits 130k to 130t through the valves 140k to 140t that can be controlled to open and close, water corresponding to the buffer stroke below the movable partition is stored.
The pressure adjusting chambers 112a and 112b are sealed with air or the like enclosed, and when the portion corresponding to the buffer stroke is accommodated in the water conduit, the pressure adjusting chambers 112a and 112b are pressurized. Assist.
図3より、昇降籠120aと可動隔壁10は上限に、可動隔壁20と内部に水を収容した昇降籠120bは下限位置にある。導水管130kから130t内には、可動隔壁20が前サイクルで押圧されたときの緩衝ストローク相当分を収容している。このとき、夫々のバルブ140aから140tは閉じており、圧力調整室112b内の圧力は圧縮されて高くなっている。ここでは、バルブ30は閉じているため、可動隔壁10と20は同状態を保持する。
上部貯水槽110に連絡する導水管131aと131b内及び131cと131dのバルブ141aから141dは通常開いている。当該導水管内は、常に当該昇降籠に収容する相当分で満たされ、同様に底面は常に高さに比例した圧力がかかっている。
From FIG. 3, the lifting rod 120a and the movable partition 10 are at the upper limit, and the movable partition 20 and the lifting rod 120b containing water inside are at the lower limit position. A portion corresponding to the buffer stroke when the movable partition 20 is pressed in the previous cycle is accommodated in the water conduits 130k to 130t. At this time, the respective valves 140a to 140t are closed, and the pressure in the pressure adjusting chamber 112b is compressed and increased. Here, since the valve 30 is closed, the movable partition walls 10 and 20 maintain the same state.
The valves 141a to 141d in the water conduits 131a and 131b and 131c and 131d communicating with the upper water tank 110 are normally open. The inside of the water conduit is always filled with an amount accommodated in the lifting / lowering rod, and similarly, the bottom surface is always subjected to a pressure proportional to the height.
図4より、内部に水を収容した昇降籠120aは下降して可動隔壁10に到達した瞬時で、これより少し前、バルブ30が開くと可動隔壁10は保持状態から下降し始め、相対する可動隔壁20は油圧シリンダ11aと11b内から、油圧シリンダ21aと21b内にパイプ40を介して油が流入して上昇する。ここで当該可動隔壁上の貯水は、介在することで当該可動隔壁を先行して下降させ直接の衝突を回避する。
相対する昇降籠120bは、上昇する前に当該昇降籠上下にある開閉口を開くと、収容した水を可動隔壁20上に残留させて上昇する。
As shown in FIG. 4, when the elevating rod 120a containing water is lowered and reaches the movable partition wall 10, and immediately before this, when the valve 30 is opened, the movable partition wall 10 starts to descend from the holding state, and the corresponding movable plate The partition wall 20 rises as oil flows from the hydraulic cylinders 11a and 11b through the pipe 40 into the hydraulic cylinders 21a and 21b. Here, the water storage on the movable partition wall intervenes to lower the movable partition wall in advance to avoid a direct collision.
When the opening / closing opening on the upper and lower sides of the lifting / lowering rod is opened before the ascending / descending rod 120b rises, the stored water remains on the movable partition wall 20 and rises.
図5より、下降する昇降籠120aにより可動隔壁10は押圧され、支持する油圧シリンダ11aと11bのロッドが緩衝ストローク分下降し、相対する可動隔壁20は支持する油圧シリンダ21aと21bにより同じストローク分上昇している。可動隔壁10が下降する時間経過とともに、導水管130aから130j内に当該緩衝ストローク相当分を収容する際に、バルブ140aから140jを順次"閉"にすることで降下速度を減速する。相対する可動隔壁20が上昇して、導水管130kから130t内に収容した相当分が当該可動隔壁下に充当されたとき、当該可動隔壁内開閉口を開くと同時にバルブ140aから140t全てを"閉"にする。
以降の可動隔壁10の下降とともに、バルブ141aと141bを順次"閉"にすることで当該昇降籠に収容相当分を上部貯水槽110に揚水する。
As shown in FIG. 5, the movable partition 10 is pressed by the descending elevating rod 120a, the rods of the supporting hydraulic cylinders 11a and 11b are lowered by the buffer stroke, and the opposing movable partition 20 is moved by the same stroke by the supporting hydraulic cylinders 21a and 21b. It is rising. With the passage of time when the movable partition wall 10 descends, the descent speed is reduced by sequentially closing the valves 140a to 140j when accommodating the buffer strokes in the water conduits 130a to 130j. When the corresponding movable partition 20 rises and the portion accommodated in the water conduits 130k to 130t is allocated below the movable partition, the movable partition is opened and the valves 140a to 140t are all closed. "To.
As the movable partition wall 10 descends thereafter, the valves 141 a and 141 b are sequentially “closed”, so that the portion corresponding to the accommodation in the lifting / lowering rod is pumped to the upper water storage tank 110.
図6より、可動隔壁10と内部に水を収容した昇降籠120aは下限に、昇降籠120bと可動隔壁20は上限位置にある。導水管130aから130j内は、可動隔壁10が先に押圧されたときの緩衝ストローク相当分が収容されており、圧力調整室112a内には空気等の媒体が圧縮され圧力が高くなっており、次サイクルで当該導水管の貯水を排出して当該可動隔壁下への充当を補助する。
可動隔壁20下は、当該可動隔壁側面と当該昇降路の内壁と気密を密にしているため、先に導水管130kから130tに収容した相当分が充当された後、当該可動隔壁内開閉口を開いて昇降籠120bに収容した相当分を更に充当する。
減速することで当該可動隔壁が下限に到達しないとき、請求項1の図示していない油圧ポンプから当該可動隔壁を支持する当該油圧シリンダ内に油を供給するのと、あわせて図示していない油タンクに排出することで下限への移動を強制できる。このような制御構造が無いとき、昇降籠への給排水後、揚水できない残量は装置外部へ排出するしか手段は無く、このことにより、昇降籠の上下動に使用した水等媒体を、装置外部へ排出するのを最小限にできる。
As shown in FIG. 6, the movable partition 10 and the lifting rod 120a containing water therein are at the lower limit, and the lifting rod 120b and the movable partition 20 are at the upper limit position. In the water conduits 130a to 130j, a portion corresponding to a buffer stroke when the movable partition wall 10 is pressed first is accommodated, and a medium such as air is compressed in the pressure adjusting chamber 112a to increase the pressure. In the next cycle, the water stored in the conduit is drained to assist under the movable partition.
Under the movable partition 20, the side surface of the movable partition and the inner wall of the hoistway are tightly sealed. Therefore, after the corresponding portion accommodated in the water conduits 130 k to 130 t is applied, the opening and closing opening in the movable partition is opened. The portion corresponding to the portion opened and accommodated in the lifting rod 120b is further applied.
When the movable partition does not reach the lower limit due to deceleration, oil not shown is supplied together with supplying oil from the hydraulic pump (not shown) to the hydraulic cylinder supporting the movable partition. It is possible to force the movement to the lower limit by discharging to the tank. When there is no such control structure, the only way to discharge the remaining amount of water that cannot be pumped up after the supply / drainage to the lifting / lowering rod is to the outside of the device. Can be minimized.
以降、同様の制御を繰り返すことで、当該昇降籠は上下動を交互に継続できる。
このように、昇降籠が自由落下した際の衝撃を緩和するとともに、位置エネルギーと等価の運動エネルギーの衝撃力により、当該昇降籠の上下動で使用した水の一部を揚水する再利用が可能である。発電手段は、例えば機械的に結合しているプーリ103bのプーリ軸に連絡する発電タービンから電力を得ることが可能である。
Thereafter, by repeating the same control, the lifting / lowering rod can continue to move up and down alternately.
In this way, it is possible to relieve the impact when the lifting rod falls freely and to recycle a part of the water used for the vertical movement of the lifting rod by the impact force of kinetic energy equivalent to potential energy It is. The power generation means can obtain electric power from, for example, a power generation turbine connected to the pulley shaft of the pulley 103b that is mechanically coupled.
図7に本発明に係る第二実施形態の水力発電装置の構造を説明する図を示す。
実施例1の図3から図6との違いは、昇降路100a内と100b内を除く上部貯水槽110以下水没しており、不純物除去装置150によりゴミ等を除去して当該上部貯水槽内に取り込んでいるのと、導水管131aから131dは当該上部貯水槽に連絡していない。
昇降籠120a内及び120b内に常に水を取り込めるので、上部貯水槽に揚水する必要が無く、下部貯水槽111a及び111b内に前記昇降籠が排水した水を装置外部の水中に全て排出できる。他は実施例1と動作を含めて同じである。
このような運用では揚水にかかるエネルギー損失が少なくなるので、発電の効率向上が期待できる。
FIG. 7 is a diagram illustrating the structure of the hydroelectric generator according to the second embodiment of the present invention.
3 to FIG. 6 in the first embodiment is that the upper water tank 110 is submerged in the hoistway 100a and the inside of the hoistway 100a, and the impurities are removed by the impurity removing device 150 to enter the upper water tank. The intake pipes 131a to 131d do not communicate with the upper water storage tank.
Since water can always be taken into the elevating rods 120a and 120b, it is not necessary to pump water into the upper water tank, and all the water drained by the elevating rods into the lower water tanks 111a and 111b can be discharged into the water outside the apparatus. Others are the same as the first embodiment including the operation.
In such operations, energy loss associated with pumping is reduced, so that improvement in power generation efficiency can be expected.
相似する2組の昇降路と昇降籠及び当該昇降路の下部に可動隔壁とを有する構造物において、当該可動隔壁と併せて具備する循環式水力発電装置に適用することで、発電出力を得ることが可能である。
