以下，一面參照圖式，一面說明本申請案的實施形態。再者，以下的實施形態在本質上為較佳的例示，並不意圖限制本申請案所揭示的技術、其應用物、或其用途的範圍。Hereinafter, referring to the drawings, an embodiment of the present application will be described. In addition, the following embodiments are essentially preferred examples, and are not intended to limit the scope of the technology disclosed in this application, its applications, or its uses.

如圖1及圖2所示，本實施形態的搖動能量變換裝置1是將藉由波浪而搖動的搖動體的搖動能量變換為動力的裝置。搖動能量變換裝置1包括門體10、收納部20、系留機構30、流入流出通道50及變換部60。再者，在圖1中，省略系留機構30的一部分。As shown in FIGS. 1 and 2, the rocking energy conversion device 1 of this embodiment is a device that converts the rocking energy of a rocking body rocked by waves into power. The swing energy conversion device 1 includes a door body 10, a storage portion 20, a mooring mechanism 30, an inflow and outflow channel 50, and a conversion portion 60. In addition, in FIG. 1, a part of the mooring mechanism 30 is omitted.

門體10設置於海中，構成藉由波浪而搖動的搖動體。門體10是作為海嘯或高潮等的應對措施而設置於港灣的翻板門式防坡堤的門體。門體10形成為稍扁平的大致矩形體狀，在基端側具有轉動軸11。門體10以轉動軸11為中心而轉動自如地設置於收納部20。The door body 10 is installed in the sea and constitutes a rocking body that is rocked by waves. The door body 10 is a door body of a flap gate type breakwater installed in a harbor as a countermeasure against a tsunami or high tide. The door body 10 is formed into a slightly flat substantially rectangular body shape, and has a rotating shaft 11 on the base end side. The door body 10 is rotatably provided in the storage portion 20 around the rotating shaft 11.

門體10自倒伏狀態藉由浮力而以轉動軸11為中心轉動而豎起（浮起）。門體10藉由豎起，來防止水自港外浸入至港內。門體10藉由系留機構30而以倒伏狀態系留。門體10構成為在倒伏狀態時，前端部12（前端側）藉由波浪而上下搖動。The door body 10 is erected (floated) by turning around the rotating shaft 11 by buoyancy from the collapsed state. The door body 10 is erected to prevent water from immersing into the harbor from outside the harbor. The door body 10 is moored by the mooring mechanism 30 in a collapsed state. The door body 10 is configured such that the front end portion 12 (front end side) is rocked up and down by waves when it is in a collapsed state.

收納部20構成容積變動部，所述容積變動部在海中被區劃，並且門體10構成區劃壁的一部分，且藉由因門體10的搖動引起的內部容積的增減而使水（海水，以下同樣）流入流出。The storage section 20 constitutes a volume change section which is divided in the sea, and the door body 10 constitutes a part of the division wall, and the water (sea water, sea water, The same below) inflow and outflow.

具體而言，收納部20設置於海底，以倒伏狀態收納門體10。收納部20形成為大致矩形體狀，門體10構成作為收納部20的區劃壁的上壁。如上所述而形成的收納部20的內部空間23成為半密閉空間。Specifically, the storage section 20 is provided on the seabed, and stores the door body 10 in a collapsed state. The storage portion 20 is formed in a substantially rectangular body shape, and the door body 10 constitutes an upper wall as a partition wall of the storage portion 20. The internal space 23 of the storage portion 20 formed as described above becomes a semi-closed space.

即，內部空間23形成於門體10的下方，即作為收納部20的區劃壁的底壁22與門體10之間。在作為收納部20的區劃壁的縱壁21與門體10的前端部12之間，設置有間隙。在內部空間23，充滿著水。再者，所述間隙理想的是僅容許門體10的搖動的儘可能小的間隙。That is, the internal space 23 is formed below the door body 10, that is, between the bottom wall 22 as the partition wall of the storage portion 20 and the door body 10. A gap is provided between the vertical wall 21 as the partition wall of the storage portion 20 and the front end portion 12 of the door body 10. The internal space 23 is filled with water. Furthermore, it is desirable that the clearance is only as small as possible to allow the swing of the door body 10.

在收納部20中，藉由門體10的前端部12上下搖動（門體10的前端部12以轉動軸11為中心轉動），而使得內部空間23的容積（以下，亦稱為內部容積）增減。而且，收納部20構成為藉由內部容積增減，而使內部空間23的水流入流出於後述流入流出通道50。In the storage portion 20, the front end portion 12 of the door body 10 is rocked up and down (the front end portion 12 of the door body 10 rotates about the rotation shaft 11), so that the volume of the internal space 23 (hereinafter, also referred to as internal volume) Increase or decrease. Moreover, the storage portion 20 is configured to allow the water in the internal space 23 to flow in and out through the inflow and outflow passage 50 described later by increasing or decreasing the internal volume.

系留機構30一面容許門體10的搖動，一面使抵抗門體10的浮力的系留力作用至門體10而系留倒伏狀態的門體10。系留機構30包括掛鉤（hook）31，三根桿（rod）34、35、36，兩個轉向連桿構件37、38，金屬絲（wire）構件39及彈簧機構43。The mooring mechanism 30 allows the swing of the door body 10 while allowing the mooring force against the buoyancy of the door body 10 to act on the door body 10 to anchor the door body 10 in the collapsed state. The mooring mechanism 30 includes a hook 31, three rods 34, 35, 36, two steering link members 37, 38, a wire member 39, and a spring mechanism 43.

掛鉤31在基端部具有軸32，且以軸32為中心轉動自如地設置，在前端側卡合於門體10的被系留部13。在掛鉤31的基端部，設置有配重（counter weight）33，所述配重33使掛鉤31旋轉至解除與被系留部13的卡合之側（圖2中左轉）。The hook 31 has a shaft 32 at the base end portion, is rotatably provided around the shaft 32, and is engaged with the moored portion 13 of the door body 10 at the front end side. At the base end portion of the hook 31, a counter weight 33 is provided, which rotates the hook 31 to the side where the engagement with the moored portion 13 is released (turn left in FIG. 2).

在掛鉤31，在靠近基端部的位置設置有銷（pin）31a，在所述銷31a依次連結著鉛垂桿34、轉向連桿構件37、水平桿35、轉向連桿構件38、鉛垂桿36及金屬絲構件39。轉向連桿構件37、轉向連桿構件38形成為雙臂曲柄（bell crank）狀。In the hook 31, a pin 31a is provided at a position near the base end, and a vertical rod 34, a steering link member 37, a horizontal rod 35, a steering link member 38, and a vertical link are sequentially connected to the pin 31a杆36及金属线件39。 The rod 36 and the wire member 39. The steering link member 37 and the steering link member 38 are formed in a bell crank shape.

金屬絲構件39纏繞於滑輪42（動滑輪），與彈簧機構43連接。滑輪42安裝於氣缸（cylinder）41的活塞桿（piston rod）41a的前端，藉由活塞桿41a的進退動作而上下移動自如。The wire member 39 is wound around the pulley 42 (movable pulley) and connected to the spring mechanism 43. The pulley 42 is attached to the front end of the piston rod 41a of the cylinder 41, and moves up and down by the forward and backward movement of the piston rod 41a.

在如上所述而構成的系留機構30中，藉由釋放氣缸41的壓力而鬆開保持力，來經由桿34、桿35、桿36及轉向連桿構件37、轉向連桿構件38，使掛鉤31的系留力鬆開。如此一來，藉由門體10的浮力及配重33的載荷，掛鉤31被向上推而解除與被系留部13的卡合。藉此，門體10藉由浮力而豎起（浮起）。In the mooring mechanism 30 configured as described above, by releasing the pressure of the air cylinder 41 and releasing the holding force, via the lever 34, the lever 35, the lever 36, the steering link member 37, and the steering link member 38, the The retention force of the hook 31 is released. In this way, due to the buoyancy of the door body 10 and the load of the weight 33, the hook 31 is pushed upward to release the engagement with the moored portion 13. With this, the door body 10 is erected (floated) by buoyancy.

又，在系留機構30中，在與門體10的卡合未被解除的範圍內，藉由彈簧機構43的伸縮作用而容許因波浪而產生的門體10的搖動。例如，當藉由波浪而使得水位下降，門體10向上方搖動時，桿34、桿35、桿36或金屬絲構件39等會在圖2中以實線的箭頭表示的方向上位移。此時，彈簧機構43伸長，而容許門體10的搖動。又，當藉由波浪而使得水位上升，門體10向下方搖動時，桿34、桿35、桿36或金屬絲構件39等會在圖2中以虛線的箭頭表示的方向上位移。此時，彈簧機構43收縮，而容許門體10的搖動。In addition, in the mooring mechanism 30, the swing of the door body 10 due to the wave is allowed by the expansion and contraction of the spring mechanism 43 within the range where the engagement with the door body 10 is not released. For example, when the water level is lowered by waves and the door body 10 swings upward, the rod 34, rod 35, rod 36, or wire member 39, etc., will be displaced in the direction indicated by the solid arrows in FIG. At this time, the spring mechanism 43 is extended to allow the door body 10 to rock. In addition, when the water level rises due to waves and the door body 10 swings downward, the rod 34, the rod 35, the rod 36, or the wire member 39, etc., will be displaced in the direction indicated by the dotted arrow in FIG. At this time, the spring mechanism 43 contracts and allows the door body 10 to rock.

流入流出通道50是與收納部20連接，水自收納部20流入流出的通道。流入流出通道50的一端與收納部20連接，與內部空間23連通。流入流出通道50的另一端與變換部60連接。The inflow and outflow channel 50 is a channel connected to the storage unit 20, and water flows in and out from the storage unit 20. One end of the inflow and outflow channel 50 is connected to the storage section 20 and communicates with the internal space 23. The other end of the inflow and outflow channel 50 is connected to the conversion unit 60.

如圖4所示，在收納部20中，藉由門體10的前端部12向上方搖動，而使得內部空間23增大而成為負壓，因此自流入流出通道50流入（抽吸）水。又，如圖5所示，在收納部20中，藉由門體10的前端部12向下方搖動，而使得內部空間23被壓縮（減少）而壓力上升，因此水流出（吐出）至流入流出通道50。再者，在圖4及圖5中，省略系留機構30。As shown in FIG. 4, in the storage portion 20, the front end portion 12 of the door body 10 is swung upward to increase the internal space 23 to become a negative pressure, and therefore water (intakes) water from the inflow/outflow passage 50. Also, as shown in FIG. 5, in the storage portion 20, the front end portion 12 of the door body 10 is rocked downward, so that the internal space 23 is compressed (reduced) and the pressure rises, so water flows out (spits out) to flow in and out. Channel 50. In addition, in FIGS. 4 and 5, the mooring mechanism 30 is omitted.

例如，當將門體10的大小設為寬度10 m×長度10 m，將門體10的搖動振寬度設為±0.5°時，流入流出（移動）的水量為約8.7 m3 。如上所述的大流量的水在流入流出通道50內流動。For example, when the size of the door body 10 is set to a width of 10 m×a length of 10 m, and the width of the shaking vibration of the door body 10 is set to ±0.5°, the amount of water flowing in and out (moving) is about 8.7 m 3 . The large-flow water as described above flows in the inflow and outflow channels 50.

變換部60將自收納部20流入流出的水的能量（流體能量）變換為動力。如圖3所示，變換部60包括氣缸61、齒條（rack）63及小齒輪（pinion）64、以及發電機66。The conversion unit 60 converts the energy (fluid energy) of the water flowing in and out of the storage unit 20 into power. As shown in FIG. 3, the conversion unit 60 includes an air cylinder 61, a rack 63 and a pinion 64, and a generator 66.

氣缸61是與流入流出通道50連接，藉由水自流入流出通道50流入流出而驅動的致動器。即，氣缸61在水自流入流出通道50流入時，活塞桿62進出（即，圖3中向上位移）。又，氣缸61在水向流入流出通道50流出時，活塞桿62後退（即，圖3中向下位移）。The air cylinder 61 is an actuator connected to the inflow and outflow passage 50 and driven by the inflow and outflow of water from the inflow and outflow passage 50. That is, the cylinder 61 moves in and out of the piston rod 62 when water flows in from the inflow and outflow passage 50 (that is, upward displacement in FIG. 3 ). In addition, when water flows out of the inflow and outflow passage 50 in the cylinder 61, the piston rod 62 moves backward (that is, moves downward in FIG. 3).

如上所述，氣缸61將自流入流出通道50流入流出的水的能量變換為線性往返運動。氣缸61的活塞桿62與齒條63連接。As described above, the cylinder 61 converts the energy of the water flowing in and out from the inflow and outflow channel 50 into linear reciprocating motion. The piston rod 62 of the cylinder 61 is connected to the rack 63.

齒條63及小齒輪64是相互咬合的動力傳遞機構。齒條63藉由活塞桿62的往返運動而進行線性往返運動。小齒輪64藉由齒條63的往返運動，而進行雙向的旋轉運動。即，小齒輪64交替地反覆進行正旋轉與逆旋轉。The rack 63 and the pinion gear 64 are power transmission mechanisms that mesh with each other. The rack 63 performs linear reciprocating motion by the reciprocating motion of the piston rod 62. The pinion 64 performs a two-way rotational movement by the reciprocating movement of the rack 63. That is, the pinion gear 64 alternately performs forward rotation and reverse rotation alternately.

對於發電機66而言，驅動軸65與小齒輪64連結。發電機66藉由小齒輪64的旋轉而驅動，從而進行發電。再者，發電機66在小齒輪64的雙向中的任一方向的旋轉時均進行發電。For the generator 66, the drive shaft 65 is connected to the pinion 64. The generator 66 is driven by the rotation of the pinion 64 to generate electricity. In addition, the generator 66 generates power when the pinion 64 rotates in either direction.

如此一來，在變換部60中，將自收納部20流入流出的水的能量（流體能量）變換為發電機66的動力。即，在搖動能量變換裝置1中，將門體10的搖動能量變換為發電機66的動力。In this way, in the conversion unit 60, the energy (fluid energy) of the water flowing in and out from the storage unit 20 is converted into the power of the generator 66. That is, in the swing energy conversion device 1, the swing energy of the door body 10 is converted into the power of the generator 66.

如以上所述，所述實施形態的搖動能量變換裝置1包括搖動體（門體10）、容積變動部（收納部20）及變換部60。搖動體設置於海中，藉由波浪而搖動。容積變動部在海中被區劃，並且搖動體構成區劃壁的一部分，藉由因搖動體的搖動而引起的內部容積的增減而使水流入流出。變換部60將自容積變動部流入流出的水的能量變換為動力。As described above, the swing energy conversion device 1 of the above-described embodiment includes the swing body (door body 10 ), the volume change unit (storage unit 20 ), and the conversion unit 60. The shaking body is set in the sea and shakes by waves. The volume change section is divided in the sea, and the rocking body constitutes a part of the dividing wall, and water flows in and out due to the increase or decrease in the internal volume caused by the rocking body. The conversion unit 60 converts the energy of the water flowing in and out from the volume change unit into motive power.

根據所述構成，可將搖動體的搖動動作變換為水（海水）的能量，且將所述水的能量變換為動力。因此，可有效利用藉由波浪而產生的物體的搖動能量。According to the above configuration, the shaking action of the shaking body can be converted into energy of water (sea water), and the energy of the water can be converted into power. Therefore, the shaking energy of objects generated by waves can be effectively used.

又，容積變動部（收納部20）形成為大致矩形體狀，所述搖動體構成作為所述區劃壁的上壁。搖動體（門體10）以設置於基端側的轉動軸11為中心而轉動自如地設置，且構成為前端側藉由波浪而上下搖動。In addition, the volume change portion (storage portion 20) is formed in a substantially rectangular body shape, and the rocking body constitutes an upper wall as the partition wall. The rocking body (door body 10) is rotatably provided with a rotating shaft 11 provided on the base end side as a center, and the front end side is rocked up and down by waves.

根據所述構成，因波浪而產生的鉛垂方向上的載荷會有效作用至搖動體。因此，可使搖動體的搖動動作有效產生。According to the above configuration, the load in the vertical direction due to the wave effectively acts on the rocking body. Therefore, the shaking motion of the shaking body can be effectively generated.

又，搖動體是自倒伏狀態藉由浮力而以轉動軸11為中心轉動而豎起的翻板門式防坡堤的門體10，且構成為在倒伏狀態時，前端側（前端部12）藉由波浪而上下搖動。根據所述構成，可利用翻板門式防坡堤的倒伏著的門體10，即利用未使用時的門體10，而產生動力。In addition, the rocking body is a door body 10 of a flap gate type breakwater that is erected by turning around the rotating shaft 11 by buoyancy from the collapsed state, and is configured such that the front end side (front end portion 12) in the collapsed state Shake up and down by waves. According to the above-described configuration, it is possible to generate power by utilizing the fallen door body 10 of the flap gate type breakwater, that is, the door body 10 when not in use.

Therefore, the load of the mooring mechanism 30 can be reduced, and the design conditions (design load) of the mooring mechanism 30 can be relaxed.

又，所述實施形態的搖動能量變換裝置1包括流入流出通道50，所述流入流出通道50與容積變動部（收納部20）連接，水自容積變動部流入流出。而且，變換部60包括致動器（氣缸61），所述致動器（氣缸61）與流入流出通道50連接，藉由水自流入流出通道50流入流出而驅動。根據所述構成，可利用簡單的構成，將水的能量變換為動力。In addition, the shaking energy conversion device 1 of the above-described embodiment includes an inflow and outflow channel 50 connected to the volume change section (storage section 20 ), and water flows in and out from the volume change section. Furthermore, the conversion unit 60 includes an actuator (cylinder 61) connected to the inflow and outflow channel 50 and driven by the inflow and outflow of water from the inflow and outflow channel 50. According to the above configuration, a simple configuration can be used to convert the energy of water into power.

再者，本申請案所揭示的技術亦可在所述實施形態中設為如下所述而構成。In addition, the technology disclosed in the present application may be configured as described below in the above embodiment.

例如，在所述實施形態中，使用氣缸61作為變換部60的致動器，但亦可設為使用將自流入流出通道50流入流出的水的能量變換為旋轉運動的水車等旋轉機械。For example, in the above-described embodiment, the air cylinder 61 is used as the actuator of the conversion unit 60, but it may also be a rotary machine such as a waterwheel that converts the energy of the water flowing in and out from the inflow and outflow channel 50 into a rotary motion.

又，在變換部60中，亦可設為將動力用於驅動發電機66以外的例如泵等設備。In addition, the conversion unit 60 may be configured to use power to drive equipment other than the generator 66 such as a pump.
