對於將本發明之潮汐發電裝置具體化之實施形態1，一邊參照圖式一邊進行說明。 The first embodiment in which the tidal power generating device of the present invention is embodied will be described with reference to the drawings.
如圖1~圖5所示，實施形態1之潮汐發電裝置具備有浮動體10、圓柱裝置20、蓋構件30、水輪40、水輪40之支撐構件50、及發電裝置60。如圖1~圖4所示，該潮汐發電裝置係安裝在構成作為構造物之狹縫式防波堤(slit type breakwater)70之塊體(block)71。狹縫式防波堤70係藉由沿著岸壁連續地設置複數個塊體71所形成。塊體71具有構成狹縫式防波堤70之一般性的構造。亦即，塊體71於被設置在岸壁時，外形沿著岸壁呈較長之長方體 形狀。又，塊體71具有前壁部72、左右壁部73、後壁部74、底壁部75、及將被該等所包圍之內部空間區隔為複數個流水室R之複數個間隔壁部76。 As shown in FIGS. 1 to 5, the tidal power generating apparatus according to the first embodiment includes a floating body 10, a cylindrical device 20, a cover member 30, a water wheel 40, a support member 50 for the water wheel 40, and a power generating device 60. As shown in FIGS. 1 to 4, the tidal power generation device is mounted on a block 71 constituting a slit type breakwater 70 as a structure. The slit breakwater 70 is formed by continuously providing a plurality of blocks 71 along the bank wall. The block 71 has a general structure constituting the slit breakwater 70. That is, when the block body 71 is disposed on the bank wall, the shape is a long rectangular parallelepiped along the bank wall. shape. Further, the block body 71 has a front wall portion 72, left and right wall portions 73, a rear wall portion 74, a bottom wall portion 75, and a plurality of partition walls that partition the internal space surrounded by the plurality of flow chambers R into a plurality of flow chambers R. 76.
如圖1及圖2所示，前壁部72係在塊體71被設置於岸壁之狀態下，上端部露出於較滿潮時之水面更上方。前壁部72係在塊體71被設置於岸壁之狀態下，相對於1個流水室R形成朝鉛垂方向延伸之3個狹縫狀之前開口部72A。相對於1個流水室R所設置之3個前開口部72A為相同形狀，且自左右中央之前開口部72A朝左右方向1個個以等間隔平行地配置。又，相對於1個流水室R所設置之3個前開口部72A，其左右中央之前開口部72A係配置於流水室R之左右中央。又，各前開口部72A其上端較滿潮時之水位高，下端則較乾潮時之水位低。如此，各前開口部72A之至少一部分始終於水中呈開口。 As shown in FIGS. 1 and 2, the front wall portion 72 is in a state in which the block body 71 is placed on the bank wall, and the upper end portion is exposed above the water surface when the tide is full. In the state in which the block body 71 is installed in the bank wall, the front wall portion 72 is formed with three slit-shaped front opening portions 72A extending in the vertical direction with respect to one of the water flowing chambers R. The three front opening portions 72A provided in the one flow chamber R have the same shape, and are arranged in parallel at equal intervals in the left-right direction from the left and right center front opening portions 72A. In addition, the left and right center front opening portions 72A are disposed at the left and right centers of the flow chamber R with respect to the three front opening portions 72A provided in one of the flow chambers R. Further, each of the front opening portions 72A has a higher water level when the upper end is fuller than the tide, and the lower end is lower than the water level when the tide is dry. In this manner, at least a portion of each of the front opening portions 72A is always open in the water.
左右壁部73及間隔壁部76係形成為等間隔。因此，形成於塊體71內之複數個流水室R呈鉛垂方向較長之長方體形狀，且具有相同容積。又，左右壁部73及間隔壁部76形成有連通相鄰接之流水室R之橫開口部73A。後壁部74在塊體71被設置於岸壁之狀態下，封閉流水室R之岸壁側。底壁部75在塊體71被設置於岸壁之狀態下，封閉流水室R之下側。流水室R之上側呈開口。亦即，塊體71於每個流水室R形成朝鉛垂方向開口之上開口部71U。 The left and right wall portions 73 and the partition wall portions 76 are formed at equal intervals. Therefore, the plurality of flow chambers R formed in the block body 71 have a rectangular parallelepiped shape that is long in the vertical direction and have the same volume. Further, the left and right wall portions 73 and the partition wall portion 76 are formed with a horizontal opening portion 73A that communicates with the adjacent flow chambers R. The rear wall portion 74 closes the bank side of the flow chamber R in a state where the block 71 is placed on the bank wall. The bottom wall portion 75 closes the lower side of the flow chamber R in a state where the block body 71 is placed on the bank wall. The upper side of the flow chamber R is open. In other words, the block body 71 forms an opening portion 71U that opens in the vertical direction in each of the flow chambers R.
潮汐發電裝置係安裝於每個流水室R。浮動體10係一個個地被收容於在塊體71內所形成之各流水室R內。該浮動體10係中空構造，且具有上表面11、下表面12、前側面13、後側面 14、及左右側面15。如圖3所示，該浮動體10於自上方觀察之俯視時，外形呈略小於流水室R之四邊形狀。 A tidal power generating device is installed in each of the flow chambers R. The floating bodies 10 are housed one by one in each of the flow chambers R formed in the block 71. The floating body 10 has a hollow structure and has an upper surface 11, a lower surface 12, a front side surface 13, and a rear side surface. 14, and the left and right sides 15. As shown in FIG. 3, the floating body 10 has a shape slightly smaller than the four sides of the flow chamber R when viewed from above.
又，該浮動體10如圖1所示，上表面11形成朝下方凹陷之凹部11C。凹部11C係設置於浮動體10之左右中央，且較前後中央略靠後壁部74側。此處，浮動體10之左右前後係自前壁部72側觀察被收容於流水室R內之浮動體10之左右前後。又，浮動體10，其凹部11C周圍之上表面係第1上表面11A，其凹部11C之底面係第2上表面11B。如此，浮動體10於上表面11形成有高低差，且具有第1上表面11A、及在低於第1上表面11A之位置所形成之第2上表面11B。作為凹部11C之底面之第2上表面11B，連結後述之圓柱裝置20之一端部(桿(rod)23之前端部)。如此，浮動體10可藉由將圓柱裝置20配置於後側，並將後述之水輪40配置於前側，而成為有效率之配置。又，浮動體10由於在重心位置之附近設置連結圓柱裝置20之一端部之凹部11C，因此易取得平衡。 Further, as shown in FIG. 1, the floating body 10 has a concave portion 11C which is recessed downward. The recessed portion 11C is provided at the center of the left and right of the floating body 10, and is slightly closer to the side of the rear wall portion 74 than the center of the front and rear. Here, the right and left of the floating body 10 are viewed from the front wall portion 72 side, and the left and right sides of the floating body 10 housed in the flow chamber R are observed. Further, in the floating body 10, the upper surface around the concave portion 11C is the first upper surface 11A, and the bottom surface of the concave portion 11C is the second upper surface 11B. In this manner, the floating body 10 has a step on the upper surface 11 and has a first upper surface 11A and a second upper surface 11B formed at a position lower than the first upper surface 11A. The second upper surface 11B which is the bottom surface of the concave portion 11C is connected to one end portion (the front end portion of the rod 23) of the cylindrical device 20 to be described later. As described above, the floating body 10 can be disposed in an efficient manner by arranging the cylindrical device 20 on the rear side and arranging the water wheel 40 to be described later on the front side. Further, since the floating body 10 is provided with the concave portion 11C that connects one end portion of the cylindrical device 20 in the vicinity of the position of the center of gravity, it is easy to balance.
又，如圖1及圖3所示，浮動體10於第1上表面11A形成連通於內部空間之連通孔11H。該浮動體10具有封閉連通孔11H之蓋16。該浮動體10可將蓋16拆下而將水注入內部空間。因此，該浮動體10可藉由注入內部空間之水量透過調整重量來調整浮力。又，浮動體10可藉由注入在設置時位於附近之海水等來進行浮力之微調整。又，浮動體10由於在搬運時之水未注入內部空間，因此重量較輕而可容易地加以搬運。蓋16始終被安裝於浮動體10構件，用以封閉連通孔11H。 Further, as shown in FIGS. 1 and 3, the floating body 10 forms a communication hole 11H that communicates with the internal space on the first upper surface 11A. The floating body 10 has a cover 16 that closes the communication hole 11H. The floating body 10 can remove the cover 16 to inject water into the internal space. Therefore, the floating body 10 can adjust the buoyancy by adjusting the weight by the amount of water injected into the internal space. Further, the floating body 10 can perform fine adjustment of buoyancy by injecting seawater or the like located in the vicinity at the time of installation. Moreover, since the floating body 10 is not injected into the internal space during transportation, the weight is light and can be easily carried. The cover 16 is always mounted to the floating body 10 member to close the communication hole 11H.
又，如圖1所示，浮動體10於下表面12形成有段差 (高低差)，且具有後側之第1下表面12A、及在高於前側之第1下表面12A之位置所形成之第2下表面12B。亦即，該浮動體10在前側(前壁部72側)具有鉛垂方向之厚度較薄(上表面11與下表面12之間隔狹窄)之前端部10A。該浮動體10在前端部10A形成供後述之水輪40之旋轉軸部41旋轉自如地插通之插通路10B。如圖1~圖3所示，插通路10B在前端部10A之左右及前後之大致中央朝鉛垂方向延伸。水輪40，其旋轉軸部41插通在浮動體10之前端部10A所形成之插通路10B，且自第2下表面12B被懸吊。 Moreover, as shown in FIG. 1, the floating body 10 is formed with a step on the lower surface 12. (High and low difference), and has a first lower surface 12A on the rear side and a second lower surface 12B formed on a position higher than the first lower surface 12A on the front side. That is, the floating body 10 has a front end portion 10A having a thinner vertical direction (a narrower interval between the upper surface 11 and the lower surface 12) on the front side (the front wall portion 72 side). In the floating body 10, a distal end portion 10A is formed with a insertion passage 10B through which a rotary shaft portion 41 of a water wheel 40, which will be described later, is rotatably inserted. As shown in FIGS. 1 to 3, the insertion passage 10B extends in the vertical direction at the center of the right and left ends of the front end portion 10A and the front and rear. The water wheel 40 has its rotating shaft portion 41 inserted through the insertion passage 10B formed at the front end portion 10A of the floating body 10, and is suspended from the second lower surface 12B.
又，如圖1~圖4所示，浮動體10分別於前端部10A之前側面13、及後側面14安裝有一對之滾輪(roller)17。一對之滾輪17係沿左右方向隔開既定之間隔而被安裝。各滾輪17平行於前側面13及後側面14且繞沿水平方向延伸之旋轉軸旋轉自如。被安裝於前側面13之一對之滾輪17，係安裝於塊體71之前壁部72之流水室R側之面，而在朝鉛垂方向延伸之一對之軌道(rail)72R上移動。被安裝於後側面14之一對之滾輪17，係安裝於塊體71之後壁部74之流水室R側之面，而在朝鉛垂方向延伸之一對之軌道74R上移動。如此，浮動體10係收容於在塊體71內所形成之流水室R內，不會朝左右方向及前後方向偏移，並根據水位之變化而上下移動自如地被導引。亦即，浮動體10可不與塊體71之前壁部72、左右壁部73、後壁部74、及間隔壁部76碰撞地根據水位之變化而平順地於流水室R內上下移動。 Further, as shown in FIGS. 1 to 4, a pair of rollers 17 are attached to the floating body 10 at the front side surface 13 and the rear side surface 14 of the front end portion 10A. A pair of rollers 17 are attached at predetermined intervals in the left-right direction. Each of the rollers 17 is parallel to the front side 13 and the rear side 14 and is rotatable about a rotation axis extending in the horizontal direction.

如圖1、圖2、及圖4所示，水輪40具有旋轉軸部41、及在旋轉軸部41之周圍所形成之旋轉翼部42。旋轉軸部41插通浮動體10之插通路10B，且上端部突出至較浮動體10之前端 部10A之上表面11更上側。 As shown in FIGS. 1 , 2 , and 4 , the water wheel 40 has a rotating shaft portion 41 and a rotating wing portion 42 formed around the rotating shaft portion 41 .

The support member 50 has an upper horizontal portion 51, a vertical portion 52, and a lower horizontal portion 53. The rotating shaft portion 41 of the water supply wheel 40 of the upper horizontal portion 51 is inserted, and is fixed to the second lower surface 12B of the floating body 10 so as to extend in the front-rear direction. The vertical portion 52 extends in the vertical direction continuously from the rear end edge of the upper horizontal portion 51. Further, the upper end portion of the vertical portion 52 is fixed to the front side surface 13 that connects the first lower surface 12A of the floating body 10 and the second lower surface 12B. The lower horizontal portion 53 is continuous with the lower end edge of the vertical portion 52 and extends in the horizontal direction in the same direction as the upper horizontal portion 51. The lower horizontal portion 53 has a bearing member 53A on the upper surface, and rotatably supports the lower end portion of the rotating shaft portion 41 of the water wheel 40. Thus, the support member 50 of the water wheel 40 extends downward from the floating body 10, and rotatably supports the lower end of the water wheel 40.
如圖5所示，發電裝置60係由流體壓泵(fluid pressure pump)61、圓柱裝置20、槽(tank)62、循環流路63、流體壓馬達(fluid pressure motor)64、發電機65、及電力調節器(power conditioner)66所構成。如圖1及圖2所示，流體壓泵61係安裝於浮動體10之前端部10A之上表面11，並於水輪40之旋轉軸部41之上端部連結有旋轉軸部61A。如圖5所示，流體壓泵61具有流出埠(outflow port)61S，其供作動用流體流出；及流入埠(inflow port)61N，其供作動用流體流入。流體壓泵61將作動用流體朝一方向抽送。 As shown in FIG. 5, the power generating device 60 is composed of a fluid pressure pump 61, a cylindrical device 20, a tank 62, a circulation flow path 63, a fluid pressure motor 64, a generator 65, And a power conditioner 66 is formed. As shown in FIGS. 1 and 2, the fluid pressure pump 61 is attached to the upper surface 11 of the front end portion 10A of the floating body 10, and the rotating shaft portion 61A is coupled to the upper end portion of the rotating shaft portion 41 of the water wheel 40. As shown in FIG. 5, the fluid pressure pump 61 has an outflow port (outflow) Port) 61S for the flow of the actuating fluid; and an inflow port 61N for the inflow of the actuating fluid. The fluid pressure pump 61 pumps the actuating fluid in one direction.
槽62貯存作動用流體，並使所貯存之作動用流體藉由空氣所加壓。槽62係安裝於浮動體10之第1上表面11A上。流體壓馬達64及發電機65係安裝於較供圓柱裝置20插入而安裝之凹部11C更後方之浮動體10之第1上表面11A。流體壓馬達64具有：流出埠64S，其供作動用流體流出；及流入埠64N，其供作動用流體流入。流體壓馬達64將作動用流體朝一方向抽送。流體壓馬達64及發電機65連結有各自之旋轉軸部64A、65A。因此，若流體壓馬達64旋轉，發電機65便進行發電。 The tank 62 stores the actuating fluid and pressurizes the stored actuating fluid by air. The groove 62 is attached to the first upper surface 11A of the floating body 10. The fluid pressure motor 64 and the generator 65 are attached to the first upper surface 11A of the floating body 10 which is located further rearward than the recess 11C to which the cylindrical device 20 is inserted. The fluid pressure motor 64 has an outflow weir 64S for the flow of the actuating fluid, and an inflow weir 64N for the inflow of the actuating fluid. The fluid pressure motor 64 pumps the actuating fluid in one direction. The fluid pressure motor 64 and the generator 65 are coupled to the respective rotating shaft portions 64A and 65A. Therefore, if the fluid pressure motor 64 rotates, the generator 65 performs power generation.
如圖5所示，循環流路63係自流體壓馬達64之流出埠64S流出之作動用流體依序流動於第1逆止閥63A、槽62、過濾器63E、流體壓泵61、第2逆止閥63B，而朝向流體壓馬達64之流入埠64N流入的流路。 As shown in Fig. 5, the circulation flow path 63 flows through the first check valve 63A, the groove 62, the filter 63E, the fluid pressure pump 61, and the second flow from the flow port 64S of the fluid pressure motor 64. The check valve 63B faces the flow path into which the inflow port 64N of the fluid pressure motor 64 flows.
該潮汐發電裝置，若圓柱裝置20收縮，作動用流體便自活塞側室21B流出，並藉由作動用流體經由第3逆止閥63C而朝向流體壓馬達64之流入埠64N流入，使作動用流體於循環流路63進行循環。此時，由於圓柱裝置20收縮而使桿側室21A之容量擴大，因此作動用流體亦自槽62經由第1連結流路67A流向桿側室21A。 In the tidal power generating device, when the cylindrical device 20 is contracted, the actuating fluid flows out from the piston side chamber 21B, and flows through the third check valve 63C toward the inflow port 64N of the fluid pressure motor 64 to cause the actuating fluid. The circulation flow path 63 is circulated. At this time, since the capacity of the rod side chamber 21A is enlarged by the contraction of the cylindrical device 20, the fluid for the operation also flows from the groove 62 to the rod side chamber 21A via the first connection flow path 67A.
又，該潮汐發電裝置，若圓柱裝置20伸長，作動用流體便自桿側室21A流出，且藉由作動用流體朝向槽62流入，使作動用流體於循環流路63進行循環。此時，由於圓柱裝置20伸長而使活塞側室21B之容量擴大，因此作動用流體亦自槽62經由設 置有第4逆止閥63D之第2連結流路67B流向活塞側室21B。 Further, in the tidal power generation device, when the cylindrical device 20 is extended, the fluid for the operation flows out from the rod side chamber 21A, and the fluid for the operation flows into the groove 62, and the fluid for operation is circulated through the circulation flow path 63. At this time, since the capacity of the piston side chamber 21B is enlarged by the extension of the cylindrical device 20, the fluid for the operation is also provided from the groove 62. The second connection flow path 67B in which the fourth check valve 63D is placed flows to the piston side chamber 21B.
如此，該潮汐發電裝置若圓柱裝置20藉由浮動體10根據因潮汐之漲退所導致水位之上下移動及因波浪所導致水位之上下移動進行上下移動而伸縮，作動用流體便於循環流路63進行循環。藉此，流體壓馬達64旋轉使發電機65進行發電。又，此時由於作動用流體流動於流體壓泵61，因此流體壓泵61亦進行旋轉。 In this way, if the volcanic power generating device 20 expands and contracts by the floating body 10 according to the upward movement of the water level due to the tidal rise and fall, and the water level moves up and down due to the wave, the operating fluid facilitates the circulation flow path 63. Loop. Thereby, the fluid pressure motor 64 rotates to cause the generator 65 to generate electric power. Further, at this time, since the fluid for the operation flows to the fluid pressure pump 61, the fluid pressure pump 61 also rotates.
又，該潮汐發電裝置，若水輪40藉由經由狹縫狀之前開口部72A而相對於流水室R流出流入之水流旋轉，流體壓泵61便進行旋轉，而使作動用流體於循環流路63進行循環。即便藉此，於該潮汐發電裝置，流體壓馬達64仍會旋轉而使發電機65進行發電。 In the tidal power generation device, when the water wheel 40 is rotated by the water flowing in and out of the flow chamber R through the slit-like front opening portion 72A, the fluid pressure pump 61 rotates, and the fluid for operation is in the circulation flow path 63. Loop. Even with this, in the tidal power generating device, the fluid pressure motor 64 rotates to cause the generator 65 to generate electric power.
電力調節器66係連接於發電機65，將直流發電機所產生之電力轉換為可於家庭中使用者。電力調節器66係安裝於浮動體10之第1上表面11A上。如此，發電裝置60(流體壓泵61、圓柱裝置20、槽62、循環流路63、流體壓馬達64、發電機65、及電力調節器66)係設置於浮動體10。 The power conditioner 66 is connected to the generator 65 to convert the power generated by the DC generator into a user at home. The power conditioner 66 is attached to the first upper surface 11A of the floating body 10. In this manner, the power generating device 60 (the fluid pressure pump 61, the cylindrical device 20, the groove 62, the circulation flow path 63, the fluid pressure motor 64, the generator 65, and the power conditioner 66) is provided in the floating body 10.
如以上所說明，實施形態1之潮汐發電裝置具備有浮動體10、圓柱裝置20、及發電裝置60。浮動體10係收容於具有前壁部72之狹縫式防波堤70，且可上下移動自如地被導引，該前壁部72在狹縫式防波堤70被設置於岸壁之狀態下，形成有至少一部分於水中呈開口之前開口部72A，且上端部露出於較水面更上方。圓柱裝置20藉由浮動體10之上下移動進行伸縮。發電裝置60藉由圓柱裝置20進行伸縮來發電。 As described above, the tidal power generating device of the first embodiment includes the floating body 10, the cylindrical device 20, and the power generating device 60. The floating body 10 is housed in a slit-type breakwater 70 having a front wall portion 72 and is slidably movable up and down. The front wall portion 72 is formed in a state in which the slit-type breakwater 70 is installed on the bank wall. A part of the opening portion 72A is opened in the water, and the upper end portion is exposed above the water surface. The cylindrical device 20 is expanded and contracted by the upper and lower movement of the floating body 10. The power generating device 60 expands and contracts by the cylindrical device 20 to generate electricity.
該潮汐發電裝置，浮動體10被收容於狹縫式防波堤 70而可上下移動自如地被導引，該狹縫式防波堤70具有形成前開口部72A之前壁部72。因此，該潮汐發電裝置係使被收容於狹縫式防波堤70內之浮動體10承受自前開口部72A流入流出之波浪或水流。因此，該潮汐發電裝置，其浮動體10承受來自特定方向之力，且浮動體10不易承受過度之波浪的力或水流。又，該潮汐發電裝置係藉由浮動體10被設置於狹縫式防波堤70內，而可容易地收容浮動體10，從而可根據水位之上下移動使浮動體10平順地上下移動。因此，該潮汐發電裝置不僅能根據因潮汐之漲退所導致水位之上下移動使浮動體10上下移動，並能根據因波浪所導致水位之上下移動使浮動體10上下移動。藉此，該潮汐發電裝置可使圓柱裝置20藉由因波浪所導致水位之上下移動而以較小之衝程進行伸縮，並使圓柱裝置20藉由因潮汐之漲退所導致水位之上下移動而以較大之衝程進行伸縮，而進行發電。 The tidal power generating device, the floating body 10 is housed in a slit type breakwater The 70-type breakwater 70 has a front wall portion 72 that forms a front opening portion 72A. Therefore, in the tidal power generation device, the floating body 10 accommodated in the slit breakwater 70 receives the wave or the flow of water flowing in and out from the front opening portion 72A. Therefore, in the tidal power generating device, the floating body 10 is subjected to a force from a specific direction, and the floating body 10 is not easily subjected to excessive wave force or water flow. Further, the tidal power generating device is provided in the slit breakwater 70 by the floating body 10, so that the floating body 10 can be easily accommodated, and the floating body 10 can be smoothly moved up and down according to the movement of the water level up and down. Therefore, the tidal power generating device can move the floating body 10 up and down according to the movement of the water level up and down due to the rise and fall of the tide, and can move the floating body 10 up and down according to the movement of the water level up and down due to the waves. Thereby, the tidal power generating device can cause the cylindrical device 20 to expand and contract with a small stroke by moving the water level up and down due to waves, and cause the cylindrical device 20 to move up and down by the rise and fall of the tide. Power is generated by stretching and contracting with a larger stroke.
因此，實施形態1之潮汐發電裝置係可良好地進行發電。 Therefore, the tidal power generation device of the first embodiment can perform power generation well.
又，該潮汐發電裝置具有作為防波堤之功能。因此，該潮汐發電裝置可防止浮動體10、圓柱裝置20、及發電裝置60因波浪之力或水流而損傷。又，該潮汐發電裝置可安裝於既有之狹縫式防波堤70而進行發電。如此，該潮汐發電裝置，不需要特地製作構造物(沉箱(caisson))，而可利用既有之狹縫式防波堤70。 Moreover, the tidal power generating device has a function as a breakwater. Therefore, the tidal power generating device can prevent the floating body 10, the cylindrical device 20, and the power generating device 60 from being damaged by the force of waves or the flow of water. Further, the tidal power generating device can be mounted on the existing slit type breakwater 70 to generate electricity. As described above, in the tidal power generation device, it is not necessary to specially fabricate a structure (caisson), and the existing slit type breakwater 70 can be utilized.
又，該潮汐發電裝置，由於水經由狹縫狀之前開口部72A流入流出，所以因波浪所導致水位之變動會在流水室R變大。因此，該潮汐發電裝置因波浪所導致浮動體10之上下移動較大，而可有效率地進行發電。又，該潮汐發電裝置，由於前開口部72A 呈朝鉛垂方向延伸之狹縫狀，因此較大之浮游物難以通過前開口部72A，而可防止較大之浮游物入侵至構造物內(流水室R)。因此，由於浮動體10不會與較大之浮游物接觸，所以不需要提升浮動體10之強度。 Further, in the tidal power generation device, since water flows in and out through the slit-shaped front opening portion 72A, the fluctuation of the water level due to the waves increases in the flow chamber R. Therefore, the tidal power generating device can efficiently generate power by causing the floating body 10 to move up and down due to waves. Moreover, the tidal power generating device is due to the front opening portion 72A Since it has a slit shape extending in the vertical direction, it is difficult for a large floating matter to pass through the front opening portion 72A, and it is possible to prevent a large floating matter from intruding into the structure (flow chamber R). Therefore, since the floating body 10 does not come into contact with a large float, it is not necessary to increase the strength of the floating body 10.
又，該潮汐發電裝置具備有蓋構件30。而且，圓柱裝置20，其桿23之前端部(一端部)係連結於浮動體10，而圓柱21之底部(另一端部)係連結於蓋構件30。又，蓋構件30在狹縫式防波堤70被設置於岸壁之狀態下，阻塞朝鉛垂方向開口之上開口部71U者。因此，該潮汐發電裝置由於利用蓋構件30阻塞狹縫式防波堤70之上開口部71U，所以可防止人或物掉落至流水室R之情形。又，於該潮汐發電裝置中，為了使圓柱裝置20藉由浮動體10之上下移動而伸縮，較佳為在被收容於狹縫式防波堤70內(流水室R)之浮動體10與被配置於狹縫式防波堤70之上部之蓋構件30之間連結圓柱裝置20。 Further, the tidal power generating device includes a cover member 30. Further, in the cylindrical device 20, the front end portion (one end portion) of the rod 23 is coupled to the floating body 10, and the bottom portion (the other end portion) of the cylinder 21 is coupled to the cover member 30. In the state in which the slit-type breakwater 70 is installed in the bank wall, the lid member 30 blocks the opening 71U in the vertical direction. Therefore, since the tidal power generating device blocks the opening portion 71U of the slit breakwater 70 by the cover member 30, it is possible to prevent a person or a thing from falling to the flow chamber R. Further, in the tidal power generating device, in order to expand and contract the cylindrical device 20 by the floating body 10, it is preferable to arrange the floating body 10 and the floating body 10 housed in the slit type breakwater 70 (flow chamber R). The cylindrical device 20 is coupled between the cover members 30 at the upper portion of the slit breakwater 70.
蓋構件30於下側之背面31形成有高低差，且具有第1背面31A、及在高於該第1背面31A之位置所形成之第2背面31B。而且，圓柱裝置20將圓柱21之底部(另一端部)連結於第2背面31B。因此，該潮汐發電裝置，由於可將圓柱裝置20之衝程設為較長，因此即便因潮汐之漲退所導致之水位變動較大，圓柱裝置20仍可追隨該水位變動而伸縮，從而進行發電。 The lid member 30 has a step on the lower surface 31 of the lower side, and has a first back surface 31A and a second back surface 31B formed at a position higher than the first back surface 31A. Further, the cylindrical device 20 connects the bottom (the other end) of the cylinder 21 to the second back surface 31B. Therefore, in the tidal power generating device, since the stroke of the cylindrical device 20 can be made long, even if the water level fluctuation due to the tidal rise and fall is large, the cylindrical device 20 can follow the water level fluctuation and expand and contract, thereby generating electricity. .
浮動體10呈中空構造，於上表面11形成有連通於內部空間之連通孔11H，並具有封閉連通孔11H之蓋16。因此，該潮汐發電裝置可藉由使水進入浮動體10內而調整重量，來調整浮力。藉此，該潮汐發電裝置可容易地進行圓柱裝置20之安裝。又， 該潮汐發電裝置，其圓柱裝置20可良好地進行伸縮，而能有效率地進行發電。又，浮動體10可藉由於設置時注入位於附近之海水等進行浮力之微調整。又，浮動體10由於在搬運時內部空間未注入水，因此可較輕地且容易地加以搬運。 The floating body 10 has a hollow structure, and a communication hole 11H communicating with the internal space is formed on the upper surface 11, and a cover 16 closing the communication hole 11H is formed. Therefore, the tidal power generating device can adjust the buoyancy by adjusting the weight by allowing water to enter the floating body 10. Thereby, the tidal power generating device can easily perform the mounting of the cylindrical device 20. also, In the tidal power generation device, the cylindrical device 20 can be expanded and contracted satisfactorily, and power generation can be performed efficiently. Further, the floating body 10 can perform fine adjustment of buoyancy by injecting seawater or the like located nearby. Moreover, since the floating body 10 is not filled with water in the internal space during transportation, it can be conveyed lightly and easily.
浮動體10於上表面11形成有高低差，且具有第1上表面11A、及在低於該第1上表面11A之位置所形成之第2上表面11B。而且，圓柱裝置20將桿23之前端部(一端部)連結於第2上表面11B。因此，該潮汐發電裝置，由於可將圓柱裝置20之衝程設為較長，因此即便因潮汐之漲退所導致之水位變動較大，圓柱裝置20仍可追蹤該水位變動而伸縮，從而進行發電。又，即便對於有高度限制之防波堤，藉由將圓柱裝置20之桿23之前端部(一端部)連結於形成在低於第1上表面11A之位置所形成之第2上表面11B，可將圓柱裝置20之衝程長度設為最大限度而有效地加以利用。 The floating body 10 is formed with a step on the upper surface 11, and has a first upper surface 11A and a second upper surface 11B formed at a position lower than the first upper surface 11A. Further, the cylindrical device 20 connects the front end portion (one end portion) of the rod 23 to the second upper surface 11B. Therefore, in the tidal power generating device, since the stroke of the cylindrical device 20 can be made long, even if the water level fluctuation due to the tidal rise and fall is large, the cylindrical device 20 can track the water level fluctuation and expand and contract, thereby generating electricity. . Further, even in the case of the height-limited breakwater, the front end portion (one end portion) of the rod 23 of the cylindrical device 20 is coupled to the second upper surface 11B formed at a position lower than the first upper surface 11A. The stroke length of the cylindrical device 20 is set to be maximized and effectively utilized.
該潮汐發電裝置，由於將水輪40懸吊於浮動體10，因此無關於因潮汐漲退所導致水位的變化，仍可使水輪40始終存在於水中。因此，該潮汐發電裝置，水輪40並不會受到因潮汐之漲退所導致水位之變化的影響，可有效率地承受水之流動進行旋轉，而使發電裝置60進行發電。又，該潮汐發電裝置，由於水輪40始終存在於水中，因此貝類等生物難以附著於水輪40，而且亦不易生鏽。所以，該潮汐發電裝置，水輪40可長期間有效率地承受水流進行旋轉，而使發電裝置60進行發電，並且可減少，維修之工時。 In the tidal power generation device, since the water wheel 40 is suspended from the floating body 10, the water wheel 40 is always present in the water regardless of the change in the water level due to the tidal rise and fall. Therefore, in the tidal power generating device, the water wheel 40 is not affected by the change in the water level due to the tidal rise and fall, and can efficiently withstand the flow of water to rotate, and the power generating device 60 can generate electricity. Further, in the tidal power generation device, since the water wheel 40 is always present in the water, it is difficult for the shellfish or the like to adhere to the water wheel 40, and it is also less likely to rust. Therefore, in the tidal power generating device, the water wheel 40 can efficiently withstand the flow of water for a long period of time, and the power generating device 60 can generate electricity, and the man-hour for maintenance can be reduced.
該潮汐發電裝置具備有自浮動體10朝下方延伸，並 旋轉自如地支撐水輪40之下端的支撐構件50。因此，該潮汐發電裝置可使水輪40良好地進行旋轉。 The tidal power generating device is provided to extend downward from the floating body 10, and The support member 50 that rotatably supports the lower end of the water wheel 40 is rotatably supported. Therefore, the tidal power generating device can rotate the water wheel 40 well.
該潮汐發電裝置將發電裝置60設置於浮動體10。因此，該潮汐發電裝置，由於發電裝置60與浮動體10一起上下移動，所以發電裝置60可不受因潮汐漲退所導致水位之變化的影響而進行發電。 This tidal power generating device sets the power generating device 60 to the floating body 10. Therefore, in the tidal power generation device, since the power generation device 60 moves up and down together with the floating body 10, the power generation device 60 can generate power without being affected by the change in the water level caused by the tidal rise and fall.
該潮汐發電裝置，即便經由前開口部72A而相對於流水室R流入流出之水流較弱，仍可藉由因潮汐之漲退等所導致水位之上下移動而使浮動體10上下移動，並使圓柱裝置20伸縮而使發電裝置60進行發電。又，該潮汐發電裝置，若處於圓柱裝置20伸縮之狀態，可將該能量作為水輪40起動時之力矩的輔助而利用。 In the tidal power generation device, even if the flow of water flowing in and out of the flow chamber R via the front opening portion 72A is weak, the floating body 10 can be moved up and down by the movement of the water level up and down due to the rise and fall of the tide, and The cylindrical device 20 expands and contracts to cause the power generating device 60 to generate electricity. Further, when the tidal power generating device is in a state in which the cylindrical device 20 is expanded and contracted, the energy can be utilized as an aid to the torque at the time of starting the water wheel 40.
該潮汐發電裝置於浮動體10之下表面12形成有高低差，且具有第1下表面12A、及在高於該第1下表面12A之位置所形成之第2下表面12B。而且，水輪40係自第2下表面12B被懸吊。因此，該潮汐發電裝置可使水輪40鉛垂方向之長度變長。藉此，該潮汐發電裝置，其水輪40承受水流之面積會變大，使水輪40可有效率地承受水流而進行旋轉，從而使發電裝置60進行發電。 The tidal power generating device has a step formed on the lower surface 12 of the floating body 10, and has a first lower surface 12A and a second lower surface 12B formed at a position higher than the first lower surface 12A. Further, the water wheel 40 is suspended from the second lower surface 12B. Therefore, the tidal power generating device can lengthen the vertical direction of the water wheel 40. As a result, in the tidal power generation device, the area of the water wheel 40 that receives the water flow is increased, and the water wheel 40 can be efficiently rotated by the water flow to cause the power generation device 60 to generate electricity.
