Description

本発明は、流体の流れによって回転する回転体を有し、該回転体の回転エネルギーを電気エネルギーに変換する流体発電装置に関する。 The present invention includes a rotating member which is rotated by the fluid flow, relates to a fluid power equipment that converts the rotational energy of the rotating body into electrical energy.

従来、流体の流れによって回転する回転体の回転エネルギーを電気エネルギーに変換する流体発電装置が存在する。この流体発電装置として、流体受入口が流体の流れにおける上流側になる位置では内部に流体を受入可能な受入可能状態となり、流体受入口が下流側になる位置では内部に流体を受入不能な受入不能状態に状態変化する複数の流体受入部材を回転体に取り付けた流体発電装置が提案されている。回転体が回転することで、流体受入部材は受入可能状態と受入不能状態を交互に繰り返していく。この回転体には、複数の流体受入部材の内の少なくとも一つが常に受入可能状態となるように、複数の流体受入部材が回転体の所定位置にそれぞれ配置されている。また、受入不能状態にある流体受入部材は、流体受入部材が収縮して流体抵抗が小さくなるので、その流体受入部材が回転体の回転の妨げとなることを抑制できる。一方、受入可能状態にある流体受入部材の内部に流体が流入して膨張し、その流体受入部材が流体の流れに押されることで、回転体を回転させる力を得ることができる。このような流体発電装置を開示したものとして、たとえば特許文献1〜3に記載されたものが知られている。   2. Description of the Related Art Conventionally, there is a fluid power generation apparatus that converts rotational energy of a rotating body that rotates by a fluid flow into electrical energy. In this fluid power generation device, when the fluid receiving port is at the upstream side in the flow of the fluid, the fluid receiving device is in a state where the fluid can be received, and when the fluid receiving port is at the downstream side, the fluid cannot be received inside. There has been proposed a fluid power generation apparatus in which a plurality of fluid receiving members that change to an impossible state are attached to a rotating body. As the rotating body rotates, the fluid receiving member alternately repeats the acceptable state and the unacceptable state. In this rotating body, a plurality of fluid receiving members are respectively arranged at predetermined positions of the rotating body so that at least one of the plurality of fluid receiving members is always in an acceptable state. In addition, the fluid receiving member that is in an unacceptable state contracts the fluid receiving member and reduces the fluid resistance, so that the fluid receiving member can be prevented from obstructing the rotation of the rotating body. On the other hand, a fluid flows into the fluid receiving member in the acceptable state and expands, and the fluid receiving member is pushed by the flow of the fluid, whereby a force for rotating the rotating body can be obtained. As what disclosed such a fluid electric power generating apparatus, what was described, for example in patent documents 1-3 is known.

また、後ろ方向に移動したときに流体を受入可能な受入可能状態になり、前方向に移動したときに流体を受入不能な受入不能状態となる流体受入部材を水中に有する浮遊体を2つ備えた水上移動具が考えられる。この水上移動具によれば、受入可能状態の流体受入部材は膨張して水の抵抗を受け、受入不能状態の流体受入部材は収縮して水の抵抗が小さくなるので、その2つの浮遊体を例えば交互に前後に移動させることで水上を前方向に進むことができる。水上移動具を開示したものとして、たとえば特許文献4に記載されたものが知られている。   In addition, there are two floating bodies that have a fluid receiving member in the water that is in a receivable state that can receive a fluid when moved in the backward direction, and in a non-acceptable state that cannot receive a fluid when moved in the forward direction. Another water moving device is conceivable. According to this water moving tool, the fluid receiving member in the accepting state expands to receive water resistance, and the fluid receiving member in the unacceptable state contracts to reduce the water resistance. For example, by moving back and forth alternately, it is possible to move forward on the water. As what disclosed the water moving tool, what was described in patent document 4, for example is known.

しかしながら、本発明者が研究したところ、流体受入部材が受入可能状態となっても、流体受入部材内部に流体が全く流入しない場合や流体受入部材内部に流体が流入するまでに相当時間がかかる場合があることが分かった。これは、受入不能状態となった流体受入部材は、流体受入口が閉じてしまい、一旦流体受入口が閉じると、回転体が回転してその流体受入部材が受入可能状態となっても、閉じている流体受入口からは流体受入部材内に流体が流入しにくくなることが原因と考えられる。流体受入部材内部に流体が全く流入しない場合には、流体の流れが回転体の回転運動として寄与できない。また、流体受入部材の内部に流体が流入し、流体受入部材が完全に膨らむまでの膨張課程では、流体受入部材に流入した流体は流体受入部材を膨らめる力として働き、回転体の回転エネルギーとして殆ど作用しない。流体受入部材内部に流体が流入するまでに時間がかかると、流体の流れが回転体の回転運動に寄与するまでに時間かかってしまう。その結果、回転体が回転しない、或いは回転体の回転数が少なくなるといった問題が生じてしまう虞がある。   However, when the present inventor has researched, even when the fluid receiving member is ready to be received, when no fluid flows into the fluid receiving member or when it takes a considerable amount of time for the fluid to flow into the fluid receiving member. I found out that This is because the fluid receiving member that has become unacceptable is closed even if the fluid receiving port is closed, and once the fluid receiving port is closed, the rotating body rotates and the fluid receiving member becomes receivable. This is probably because the fluid is less likely to flow into the fluid receiving member from the fluid receiving port. If no fluid flows into the fluid receiving member, the fluid flow cannot contribute to the rotational motion of the rotating body. In addition, in the expansion process until the fluid flows into the fluid receiving member and the fluid receiving member completely expands, the fluid flowing into the fluid receiving member acts as a force to expand the fluid receiving member, and the rotating body rotates. It hardly acts as energy. If it takes time for the fluid to flow into the fluid receiving member, it takes time for the fluid flow to contribute to the rotational motion of the rotating body. As a result, there is a risk that the rotating body does not rotate or the rotational speed of the rotating body decreases.

また、水上移動具でも、上述の回転体と同様に、浮遊体を後ろ方向に移動しても流体受入部材内部に流体が全く流入しない場合や流体受入部材内部に流体が流入するまでに時間がかかってしまう場合があることが分かった。これらの場合、浮遊体を前後方向に移動させても移動できない、或いは水上を移動する移動量が小さくなるといった問題が生じてしまう虞がある。   Also, in the case of the water moving tool, as in the case of the above-described rotating body, when no fluid flows into the fluid receiving member even when the floating body is moved backward, it takes time until the fluid flows into the fluid receiving member. It turns out that it may take. In these cases, there may be a problem that the floating body cannot move even if it is moved in the front-rear direction, or the amount of movement that moves on the water becomes small.

本発明の実施の形態に係る流体発電装置を図面にしたがって説明する。   A fluid power generation apparatus according to an embodiment of the present invention will be described with reference to the drawings.

まず、図1〜図5に基づいて第1の実施形態を説明する。図1は、本発明の第1の実施形態に係る流体発電装置1を示す平面図であり、図2は、図1の流体発電装置1の側面図である。   First, a first embodiment will be described with reference to FIGS. FIG. 1 is a plan view showing a fluid power generation apparatus 1 according to the first embodiment of the present invention, and FIG. 2 is a side view of the fluid power generation apparatus 1 of FIG.

図1および図2に示すように、本実施の形態に係る流体発電装置1は、水面又は海面に浮くフローティングユニット4と、フローティングユニット4を所定領域に係留する係留手段9とを有している。フローティングユニット4は、流体の流れ(水流)によって回転する回転体3と、回転体3の上面に設けられた発電機7とを備えている。なお、図1では発電機7を省略している。回転体3の下面(着水面)には、複数の流体受入部材5が取り付けられている。   As shown in FIGS. 1 and 2, the fluid power generation apparatus 1 according to the present embodiment includes a floating unit 4 that floats on the surface of the water or the sea, and mooring means 9 that anchors the floating unit 4 in a predetermined region. . The floating unit 4 includes a rotating body 3 that rotates by a fluid flow (water flow), and a generator 7 provided on the upper surface of the rotating body 3. In FIG. 1, the generator 7 is omitted. A plurality of fluid receiving members 5 are attached to the lower surface (landing surface) of the rotating body 3.

係留手段9は、フローティングユニット4を支持する支持アーム11が連結された矩形状の枠体から成るフレーム18と、岩場等の不動領域に固定された支柱13と、フレーム18と支柱13との間に回動自在に連結されたリンク部材15とを有している。リンク部材15は、回転自在に支柱13に接続された主リンク15aと、その主リンク15aにそれぞれ回転自在に接続された一対の接続リンク15bとを備えている。支柱13と主リンク15aにはジャッキ20の端部がそれぞれ連結されている。洪水が発生したときなど、必要なときには、主リンク15aをジャッキ20により上方に持ち上げることで、フローティングユニット4を水面より引き揚げることができる。   The mooring means 9 includes a frame 18 formed of a rectangular frame to which a support arm 11 that supports the floating unit 4 is connected, a support 13 fixed to a fixed area such as a rocky place, and a frame 18 and a support 13. And a link member 15 that is rotatably connected to the link member 15. The link member 15 includes a main link 15a that is rotatably connected to the column 13, and a pair of connection links 15b that are rotatably connected to the main link 15a. The ends of the jacks 20 are connected to the support columns 13 and the main links 15a, respectively. When necessary, such as when a flood occurs, the floating unit 4 can be lifted from the water surface by lifting the main link 15a upward by the jack 20.

支持アーム11の先端部にはベアリング17が固定されており、このベアリング17を介して発電機7の回転軸7aが支持アーム11に接続されている。また、発電機7の本体7bは、図示しない固定機構で、フレーム18に固定されている。   A bearing 17 is fixed to the tip of the support arm 11, and the rotating shaft 7 a of the generator 7 is connected to the support arm 11 through the bearing 17. The main body 7b of the generator 7 is fixed to the frame 18 by a fixing mechanism (not shown).

水流によって生じる回転体3の回転エネルギーは発電機7によって電気エネルギーに変換され、得られた電力は図示しないケーブルにより蓄電器に蓄えられ、あるいは電力消費体へ送られる。   Rotational energy of the rotator 3 generated by the water flow is converted into electrical energy by the generator 7, and the obtained electric power is stored in a capacitor by a cable (not shown) or sent to an electric power consumer.

図3は、水面に浮く回転体3をその下面(着水面)側から見た斜視図である。   FIG. 3 is a perspective view of the rotating body 3 floating on the water surface as viewed from the lower surface (landing surface) side.

回転体3は発泡スチロール等の浮力が得られる材質で円盤状に形成されており、その下面には周方向に略等間隔に複数の流体受入部材5が設けられている。本実施形態では、回転体3をその材質による浮き性によって浮かせているが、内部を空洞化して浮力を得るようにしてもよい。また、本実施形態では、この流体受入部材5を8つ設ける例を示すが、流体受入部材5は2つ以上であればよい。回転体3の中央部は発電機7の回転軸7aを固定する軸ベース19となっている。   The rotating body 3 is formed in a disk shape from a material that can obtain buoyancy, such as polystyrene foam, and a plurality of fluid receiving members 5 are provided on the lower surface thereof at substantially equal intervals in the circumferential direction. In the present embodiment, the rotating body 3 is floated by the floatability of the material, but the inside may be hollowed to obtain buoyancy. In the present embodiment, an example in which eight fluid receiving members 5 are provided is shown, but two or more fluid receiving members 5 may be provided. A central portion of the rotating body 3 is a shaft base 19 that fixes the rotating shaft 7 a of the generator 7.

流体受入部材5は、ビニール樹脂等の柔軟性を有する材料でポケット状に形成されており、流体(水)が流入する流体受入口21を回転体3の回転方向に対して同一向きにして配置されている。流体受入部材5なお、流体受入部材5を袋状に形成し、その袋状の一部分を回転体3に貼り付けても良い。この流体受入部材5は、水があまり漏れないように数箇所でねじ等により回転体3に固定されている。もちろん、回転体3と接する部分を全て固着してもよい。   The fluid receiving member 5 is formed in a pocket shape with a flexible material such as vinyl resin, and the fluid receiving port 21 into which the fluid (water) flows is arranged in the same direction with respect to the rotation direction of the rotating body 3. Has been. Fluid receiving member 5 Note that the fluid receiving member 5 may be formed in a bag shape, and a part of the bag shape may be attached to the rotating body 3. The fluid receiving member 5 is fixed to the rotating body 3 with screws or the like at several points so that water does not leak so much. Of course, all the portions in contact with the rotating body 3 may be fixed.

流体受入部材5の、流体受入口21を画定する縁部50の一部(以下、対向縁部501と称する)は、回転体3に対して接離自在に配置されている。その対向縁部501が、回転体3から離れることで、流体受入口21の大きさが拡大する。   A part of the edge portion 50 (hereinafter referred to as an opposite edge portion 501) that defines the fluid receiving port 21 of the fluid receiving member 5 is disposed so as to be able to contact with and separate from the rotating body 3. The size of the fluid receiving port 21 is increased when the facing edge portion 501 is separated from the rotating body 3.

流体受入部材5には、流体導入部材16が設けられている。この流体導入部材16は、流体受入部材5より剛性が高く水流を受けても変形しない板状の部材であり、図5(a)および図5(b)に示すように、流体受入部材5の内部であって対向縁部501に貼り付けられた基部160と、対向縁部501から流体受入部材5の外部側に突出した突出部161とを有している。この突出部161は、突出端に向けて対向縁部501が回転体3から離れる方向に傾斜している。
図3では分かり易いように、各流体受入部材5が完全に膨れた状態、換言すれば、回転体3に最も大きな回転エネルギーを与える最大の抵抗形状になった状態を示しているが、水流が作用しない状態ではこのような保形性は有しておらず、上記柔軟性によって型崩れして扁平化した形状となる。
The fluid receiving member 5 is provided with a fluid introducing member 16. The fluid introduction member 16 is a plate-like member that is higher in rigidity than the fluid receiving member 5 and does not deform even when it receives a water flow. As shown in FIGS. 5A and 5B, the fluid introducing member 5 There is a base portion 160 that is inside and attached to the opposing edge portion 501, and a protruding portion 161 that protrudes from the opposing edge portion 501 to the outside of the fluid receiving member 5. The protruding portion 161 is inclined in a direction in which the opposing edge portion 501 is separated from the rotating body 3 toward the protruding end.
For easy understanding, FIG. 3 shows a state in which each fluid receiving member 5 is completely swollen, in other words, a state in which the maximum resistance shape is given to the rotating body 3 with the largest rotational energy. In a state where it does not act, it does not have such shape retaining property, and is deformed and flattened by the above flexibility.

図4は、水流によって図1に示す回転体3が回転する状態を示す斜視図であり、図5(a)は、図4に示す流体受入部材5が膨らんだ状態を示す図、図5(b)は、図4に示す流体受入部材5が扁平状となった状態を示す図である。   4 is a perspective view showing a state in which the rotating body 3 shown in FIG. 1 is rotated by a water flow, FIG. 5A is a view showing a state in which the fluid receiving member 5 shown in FIG. 4 is inflated, and FIG. FIG. 5B is a diagram illustrating a state where the fluid receiving member 5 illustrated in FIG. 4 is flat.

図4に示すように、破線矢印で示す水流は回転体3の全体に対して同一向きに流れる。この流れに対して図4の手前側の流体受入部材5は、流体受入口21が水流の上流側に位置し水を受入可能な受入可能状態となっている。この受入可能状態では、流体受入口21が水流と対向するため、図5(a)に示すように、水が流体受入口21から入り込み、流体受入部材5が膨れる。膨れた流体受入部材5は、水流に対して抵抗体となり、回転体3を図4の矢印R方向に回転させる回転エネルギーを生じさせる。   As shown in FIG. 4, the water flow indicated by the broken-line arrows flows in the same direction with respect to the entire rotating body 3. With respect to this flow, the fluid receiving member 5 on the near side in FIG. 4 is in a receivable state in which the fluid receiving port 21 is located on the upstream side of the water flow and can receive water. In this acceptable state, since the fluid receiving port 21 faces the water flow, water enters from the fluid receiving port 21 and the fluid receiving member 5 expands as shown in FIG. The swollen fluid receiving member 5 becomes a resistor against the water flow, and generates rotational energy for rotating the rotating body 3 in the direction of arrow R in FIG.

水が入り込んで膨れた流体受入部材5は回転体3の回転に伴って移動する。流体受入部材5が一定の固定形状を有している場合、図4の奥側の流体受入部材5は回転体3をR方向とは逆向きに回転させる抵抗体となり、回転エネルギーが極端に弱まるか拮抗して回転しない状態となる。   The fluid receiving member 5 swelled by the water moves as the rotating body 3 rotates. When the fluid receiving member 5 has a fixed shape, the fluid receiving member 5 on the back side in FIG. 4 becomes a resistor that rotates the rotating body 3 in the direction opposite to the R direction, and the rotational energy is extremely weakened. Or it will antagonize and it will be in a state where it does not rotate.

本実施形態における流体受入部材5は、回転体3の回転により流体受入部材5が移動して流体受入口21が流れの下流側(図4の奥側)に位置すると流体を受入不能な受入不能状態になる。流体受入部材5は柔軟性を有する材質で形成されているので、受入不能状態で、その流体受入部材5が流体受入口21が存在する側とは反対側から水流を受けると、図5(b)に示すように、流体受入部材5内部の水が吐き出されて流体受入部材5は扁平状となり流体受入口21は閉じる。また、流体受入部材5が扁平状となると、その流体受入部材5が回転を弱める抵抗体としての影響は殆どなくなる。   The fluid receiving member 5 in the present embodiment cannot receive a fluid when the fluid receiving member 5 is moved by the rotation of the rotating body 3 and the fluid receiving port 21 is located on the downstream side (back side in FIG. 4) of the flow. It becomes a state. Since the fluid receiving member 5 is formed of a flexible material, when the fluid receiving member 5 receives a water flow from the side opposite to the side where the fluid receiving port 21 exists in a state where the fluid receiving member 5 cannot receive the fluid, FIG. ), The water inside the fluid receiving member 5 is discharged, the fluid receiving member 5 becomes flat, and the fluid receiving port 21 is closed. Further, when the fluid receiving member 5 is flat, the fluid receiving member 5 has almost no influence as a resistor that weakens the rotation.

このような構成とすれば、回転体3を水面に浮かべておくだけでどの方向の水流も同様に利用することができ、簡易かつ低コストな構成で発電効率を高めることができる。   With such a configuration, the water flow in any direction can be used in the same manner simply by floating the rotating body 3 on the water surface, and the power generation efficiency can be increased with a simple and low-cost configuration.

本実施形態では流体受入部材5の変形容易性(可変性)を柔軟な材質によって得ることとしたが、ヒンジ等により予め折り畳み可能な折り目を付けてにしておけば、柔軟性を有する材質ではなくても変形容易性を得ることができる。   In the present embodiment, the deformability (variability) of the fluid receiving member 5 is obtained by a flexible material. However, if a foldable fold is provided in advance by a hinge or the like, the fluid receiving member 5 is not a flexible material. However, the ease of deformation can be obtained.

また、対向縁部501には、流体導入部材16が取り付けられているので、図5(b)に示すように流体受入部材5が受入不能状態となった後、回転体3の回転に伴って受入可能状態に状態変化すると、流体受入部材5の内部に水が素早く流入する。流体導入部材16が存在しない場合には、受入可能状態となっても閉じた流体受入口21が水流によって回転体3に押さえ付けられてしまい、流体受入口21が閉じたままになってしまうことがある。本実施形態では、流体受入部材5の流体受入口21が上流側に位置すると、突出部161に向かって流れる水は、突出部161によって流体受入口21の口内に向かう。すなわち、突出部161によって、流体受入部材5の内部に水を導いて流体受入口21を素早く確実に拡大させることができる。また、突出部161に向かう水流は、流体導入部材16(対向縁部501)を回転体側縁部から離間させる力としても作用するので、流体受入口21をより素早く確実に拡大させることができる。   Further, since the fluid introduction member 16 is attached to the opposing edge portion 501, the fluid receiving member 5 becomes unacceptable as shown in FIG. When the state changes to the acceptable state, water quickly flows into the fluid receiving member 5. When the fluid introduction member 16 is not present, the closed fluid receiving port 21 is pressed against the rotating body 3 by the water flow even when the receiving state is enabled, and the fluid receiving port 21 remains closed. There is. In the present embodiment, when the fluid receiving port 21 of the fluid receiving member 5 is located on the upstream side, the water flowing toward the protruding portion 161 is directed into the mouth of the fluid receiving port 21 by the protruding portion 161. That is, the protrusion 161 can quickly and surely expand the fluid receiving port 21 by guiding water into the fluid receiving member 5. Further, the water flow toward the projecting portion 161 also acts as a force for separating the fluid introduction member 16 (opposing edge portion 501) from the rotating body side edge portion, so that the fluid receiving port 21 can be expanded more quickly and reliably.

この実施形態によれば、受入可能状態となった流体受入部材5を素早く確実に膨らませることができるので、回転体3を効率よく回転させて流体発電装置1の発電効率を高めることができる。   According to this embodiment, since the fluid receiving member 5 that has been in the acceptable state can be quickly and reliably inflated, the power generation efficiency of the fluid power generation apparatus 1 can be increased by efficiently rotating the rotating body 3.

続いて、図6及び図7に基づいて第2の実施形態を説明する。なお、上記実施の形態で説明した構成上及び機能上の重複した説明は特に必要がない限り省略し、要部のみ説明する(以下の他の実施形態において同じ)。   Next, a second embodiment will be described based on FIGS. Note that redundant descriptions of the configuration and functions described in the above embodiment will be omitted unless particularly necessary, and only the main part will be described (the same applies to other embodiments below).

図6は、第2の実施形態に係る流体発電装置の設置状態を示す側面図であり、図7は、図6に示す回転体の要部を示す斜視図である。   FIG. 6 is a side view showing an installation state of the fluid power generation apparatus according to the second embodiment, and FIG. 7 is a perspective view showing a main part of the rotating body shown in FIG.

本実施形態における流体発電装置1は、図6に示すように、例えば川の水が流れ落ちる傾斜面41に設置して使用するものである。   As shown in FIG. 6, the fluid power generation apparatus 1 according to the present embodiment is used by being installed on an inclined surface 41 where, for example, river water flows down.

流体発電装置1は、回転体32と、傾斜面41に間隔をおいて固定された2つの脚43とを備えている。回転体32は、各脚43に回転可能に支持された支持部材としての2つのローラ45と、これらのローラ45間に循環移動可能に掛け回された移動体で且つ回転体本体としての無端状のベルト47と、ベルト47の表面に略等間隔に配置された複数の流体受入部材5とを有している。この流体受入部材5の流体受入口21には、流体導入部材16が取り付けられている。また、図7に示すように、一方のローラ45には、発電機7の回転軸7aが固定されている。この回転軸7aは、ベアリング17を介して支持アーム11に支持されている。また、発電機7の本体7bは、図示しない固定機構により回転不能に固定されている。なお、ベルト47を歯付ベルトとし、ローラ45を歯付ベルトとかみ合う歯を設けた歯付プーリとしてもよい。   The fluid power generation device 1 includes a rotating body 32 and two legs 43 fixed to the inclined surface 41 with a space therebetween. The rotating body 32 includes two rollers 45 as support members that are rotatably supported by the legs 43, and a moving body that is looped around these rollers 45 so as to circulate and is endless as a main body of the rotating body. Belt 47 and a plurality of fluid receiving members 5 arranged on the surface of the belt 47 at substantially equal intervals. A fluid introducing member 16 is attached to the fluid receiving port 21 of the fluid receiving member 5. As shown in FIG. 7, the rotating shaft 7 a of the generator 7 is fixed to one roller 45. The rotating shaft 7 a is supported by the support arm 11 via a bearing 17. The main body 7b of the generator 7 is fixed so as not to rotate by a fixing mechanism (not shown). The belt 47 may be a toothed belt, and the roller 45 may be a toothed pulley provided with teeth that mesh with the toothed belt.

図6に波線で示す矢印は、川の流れを示している。流体受入口21が川の流れの上流側に位置し、受入可能状態となっている流体受入部材5は水流を受けて流体受入部材5が膨らんでいる。この受入可能状態の流体受入部材5が水流を受けることで、ベルト47を回転させる回転エネルギーが生じている。流体受入口21が川の流れの下流側に位置し、受入不能状態となっている流体受入部材5は扁平状となり、回転を弱める抵抗体としての影響は殆どなくなる。   The arrow shown with a wavy line in FIG. 6 shows the flow of the river. The fluid receiving member 21 is located on the upstream side of the river flow, and the fluid receiving member 5 that is in a receivable state receives a water flow, and the fluid receiving member 5 is swollen. Rotational energy for rotating the belt 47 is generated by the fluid receiving member 5 in the acceptable state receiving the water flow. The fluid receiving member 21 located on the downstream side of the river flow and being in an unacceptable state has a flat shape, and the influence as a resistor that weakens the rotation is almost eliminated.

扁平状となった流体受入部材5の流体受入口21が上流側に位置すると、突出部161に向かって流れる水は、突出部161によって流体受入口21の口内に向かう。すなわち、突出部161によって、流体受入部材5の内部に水を導くことができる。また、流体受入口21を素早く確実に拡大させることができる。 この実施形態によれば、受入可能状態となった流体受入部材5を素早く確実に膨らませることができるので、回転体3を効率よく回転させて流体発電装置1の発電効率を高めることができる。   When the fluid receiving port 21 of the fluid receiving member 5 having a flat shape is positioned on the upstream side, the water flowing toward the protruding portion 161 is directed into the mouth of the fluid receiving port 21 by the protruding portion 161. That is, water can be guided into the fluid receiving member 5 by the protrusion 161. Moreover, the fluid receiving port 21 can be expanded quickly and reliably. According to this embodiment, since the fluid receiving member 5 that has been in the acceptable state can be quickly and reliably inflated, the power generation efficiency of the fluid power generation apparatus 1 can be increased by efficiently rotating the rotating body 3.

また、この実施形態では、地面側(図6における下側)で受入可能状態と成る流体受入部材5を設けているので、川の水が少なく、水面が低い場合であっても、流体受入部材5が水流を受けて回転体3を回転させることができる。   Moreover, in this embodiment, since the fluid receiving member 5 that is in an acceptable state on the ground side (the lower side in FIG. 6) is provided, the fluid receiving member even when there is little river water and the water surface is low. 5 can receive the water flow and rotate the rotating body 3.

続いて、図8に基づいて第3の実施形態を説明する。図8の実施形態は、垂直方向に流れ落ちる川の滝部分に流体発電装置を設置する形態である。   Next, a third embodiment will be described based on FIG. The embodiment of FIG. 8 is a form in which the hydroelectric generator is installed in the waterfall portion of the river that flows down in the vertical direction.

図8は、第3の実施形態に係る流体発電装置を示す側面図である。   FIG. 8 is a side view showing a fluid power generation apparatus according to the third embodiment.

これまでの実施形態は主に水流による力を受けることで回転体を回転させる回転エネルギーを得るものであった。これに対し、この実施形態では、主に流体受入部材5に流入した水の重量により回転エネルギーを得る点が異なる。   In the embodiments so far, the rotational energy for rotating the rotating body is mainly obtained by receiving the force of the water flow. On the other hand, this embodiment is different in that rotational energy is obtained mainly by the weight of water flowing into the fluid receiving member 5.

本実施形態における流体発電装置1の回転体34は、ローラ45と、そのローラ45に巻き掛けられた無端状のベルト47と、ベルト47の表面に略等間隔に配置された複数の流体受入部材5とを有している。ローラ45はベルト47の内側であって、ベルト47の上部に設けられている。流体受入部材5の流体受入口21には、流体導入部材16が取り付けられている。流体受入口21が流体受入部材5の上側に位置している受入可能状態では、流れ落ちてくる滝部の水が、流体導入部材16に導かれて流体受入部材5内部に流入し、流体受入部材5が膨らんでいる。この受入可能状態の流体受入部材5の内部に流入した水の重量により、図8における反時計回りにベルト47を回転させる回転エネルギーが生じている。流体受入口21が流体受入部材5の下側に位置し、受入不能状態となっている流体受入部材5は扁平状態となり、滝部を流れ落ちてくる水が流体受入部材5の内部に流入することはない。また、受入不能状態では、流体受入部材5は、滝部の水から離れた位置にあるので、水の流れがベルト47の回転を妨げることもない。さらに、滝部の水が増えた場合でも、受入不能状態にある流体受入部材5は、扁平状となっているので、回転体34の回転を弱める抵抗体としての影響は殆どない。   The rotating body 34 of the fluid power generation device 1 in the present embodiment includes a roller 45, an endless belt 47 wound around the roller 45, and a plurality of fluid receiving members disposed on the surface of the belt 47 at substantially equal intervals. 5. The roller 45 is provided inside the belt 47 and above the belt 47. A fluid introducing member 16 is attached to the fluid receiving port 21 of the fluid receiving member 5. In the acceptable state in which the fluid receiving port 21 is positioned above the fluid receiving member 5, the water of the falling waterfall portion is guided to the fluid introducing member 16 and flows into the fluid receiving member 5, and the fluid receiving member 5. Is inflated. Rotational energy for rotating the belt 47 counterclockwise in FIG. 8 is generated by the weight of the water flowing into the fluid receiving member 5 in the acceptable state. The fluid receiving member 21 is located on the lower side of the fluid receiving member 5, and the fluid receiving member 5, which is in an unacceptable state, is in a flat state, and water flowing down the waterfall portion flows into the fluid receiving member 5. Absent. In the non-acceptable state, the fluid receiving member 5 is located away from the water in the waterfall portion, so that the flow of water does not hinder the rotation of the belt 47. Furthermore, even when the water in the waterfall increases, the fluid receiving member 5 that is in an unacceptable state has a flat shape, so that there is almost no influence as a resistor that weakens the rotation of the rotating body 34.

発電機7は、滝部よりも上方に設けられた台座61に固定されている。ローラ45は、発電機7に固定されたアーム62によって回転自在に保持されている。アーム62の内部にはローラ45の回転を伝達するチェーンなどの図示しない回転伝達機構が設けられており、ローラ45の回転は、駆動チェーンを介して発電機7に伝達されている。なお、ベルト47に流体受入部材5を多数配置することにより、水量が少なくとも大きな回転力を得ることが出来る。   The generator 7 is fixed to a pedestal 61 provided above the waterfall. The roller 45 is rotatably held by an arm 62 fixed to the generator 7. A rotation transmission mechanism (not shown) such as a chain for transmitting the rotation of the roller 45 is provided inside the arm 62, and the rotation of the roller 45 is transmitted to the generator 7 through the drive chain. Note that by arranging a large number of fluid receiving members 5 on the belt 47, a rotational force with at least a large amount of water can be obtained.

この実施形態でも、受入可能状態となった流体受入部材5を素早く確実に膨らませ、回転体34を効率よく回転させて流体発電装置1の発電効率を高めることができる。   Also in this embodiment, the fluid receiving member 5 that is in the acceptable state can be quickly and reliably inflated, and the rotating body 34 can be efficiently rotated to increase the power generation efficiency of the fluid power generation apparatus 1.

引き続き、図9および図10に基づいて第4の実施形態を説明する。   Next, the fourth embodiment will be described based on FIGS. 9 and 10.

図9は、第4の実施形態に係る回転体36をその下面(着水面)側から見た斜視図である。   FIG. 9 is a perspective view of the rotating body 36 according to the fourth embodiment viewed from the lower surface (landing surface) side.

本実施形態では、流体受入部材5の流体受入口21を画定する縁部50に、柔軟性のある厚手の開口維持部材51を備えている。流体受入部材5の、流体受入口21を画定する縁部50以外の部分は、例えば厚さ1mmのビニール樹脂等の柔軟性を有する材料で形成されている。開口維持部材51は、厚さ2mm以上の弾性体(ここではシリコンゴム)で形成されている。   In the present embodiment, a flexible thick opening maintaining member 51 is provided on the edge 50 that defines the fluid receiving port 21 of the fluid receiving member 5. The portion of the fluid receiving member 5 other than the edge portion 50 that defines the fluid receiving port 21 is formed of a flexible material such as a vinyl resin having a thickness of 1 mm, for example. The opening maintaining member 51 is formed of an elastic body (here, silicone rubber) having a thickness of 2 mm or more.

図9に示すように、図9の手前側の流体受入部材5は、流体受入口21が水流の上流側に位置し水を受入可能な受入可能状態となっている。この受入可能状態では、流体受入口21が水流と対向するため、水が流体受入口21から入り込み、流体受入部材5が膨れる。膨れた流体受入部材5は、水流に対して抵抗体となり、回転体36を回転させる回転エネルギーを生じさせる。   As shown in FIG. 9, the fluid receiving member 5 on the near side in FIG. 9 is in a receivable state in which the fluid receiving port 21 is located on the upstream side of the water flow and can receive water. In this acceptable state, since the fluid receiving port 21 faces the water flow, water enters from the fluid receiving port 21 and the fluid receiving member 5 expands. The swollen fluid receiving member 5 becomes a resistor against the water flow and generates rotational energy for rotating the rotating body 36.

図9の奥側の流体受入部材5は、流体受入口21が水流の下流側に位置し水を受入不能な受入不能状態となっている。受入不能状態では、流体受入部材5は、流体受入口21が存在する側とは反対側から水流を受け、流体受入部材5内部の水が吐き出されて扁平状となる。ただし、本実施形態では、受入不能状態でも流体受入部材5に開口維持部材51を備えているので、流体受入口21は完全に閉じずに開口の一部は維持される。   The fluid receiving member 5 on the back side in FIG. 9 is in an unacceptable state in which the fluid receiving port 21 is located on the downstream side of the water flow and cannot receive water. In the unacceptable state, the fluid receiving member 5 receives a water flow from the side opposite to the side where the fluid receiving port 21 exists, and the water inside the fluid receiving member 5 is discharged and becomes flat. However, in this embodiment, since the fluid receiving member 5 includes the opening maintaining member 51 even in a state where the fluid cannot be received, the fluid receiving port 21 is not completely closed and a part of the opening is maintained.

図10(a)は図9に示す流体受入部材5が膨らんだ状態を示す図、図10(b)は図10(a)のA矢視図、図10(c)は、図9に示す流体受入部材5が扁平状となった状態を示す図、図10(d)は図10(c)のB矢視図である。   10A is a view showing a state in which the fluid receiving member 5 shown in FIG. 9 is swollen, FIG. 10B is a view taken along arrow A in FIG. 10A, and FIG. 10C is shown in FIG. FIG. 10D is a view showing a state in which the fluid receiving member 5 is flattened, and FIG. 10D is a view as seen from the direction of arrow B in FIG.

受入可能状態では、流体受入口21が水流と対向するため、図10(a)に示すように、水が流体受入口21から入り込み、流体受入部材5が膨れる。図10(b)に示すように、流体受入部材5が膨れた状態では、開口維持部材51は円弧状をしている。また、開口維持部材51は、水流のない無負荷時にも自身の弾性による復元力によって流体受入口21が最も拡大した形状である円弧状をしている。図10(c)に示すように、受入不能状態の流体受入部材5は流体受入口21が存在する側とは反対側から水流を受ける。この受入不能状態では、流体受入部材5内部の水が吐き出されて流体受入部材5の流体受入口21とは反対側の部分は扁平状となる。図10(d)に示すように、この受入不能状態にある流体受入口21は、水流を受けてある程度変形し、受入可能状態にあるときよりも流体受入口21が縮小するものの、開口維持部材51の弾性により完全に閉じずに体受入口21は多少の開口が維持される。すなわち、開口維持部材51は、受入不能状態にある流体受入口21が密閉されない形状を自身の弾性によって維持する。なお、本実施形態では、流体受入口21を画定する縁部50に開口維持部材51を設けているが、受入不能状態でも流体受入口21が密閉しない位置であれば、流体受入部材5の別の位置に開口維持部材51を設けてもよい。また、開口維持部材51を金属製のバネで構成してもよい。   In the acceptable state, since the fluid receiving port 21 faces the water flow, water enters from the fluid receiving port 21 and the fluid receiving member 5 expands as shown in FIG. As shown in FIG. 10B, the opening maintaining member 51 has an arc shape when the fluid receiving member 5 is expanded. Further, the opening maintaining member 51 has an arc shape in which the fluid receiving port 21 is expanded most by a restoring force due to its elasticity even when there is no water flow and no load is applied. As shown in FIG. 10C, the fluid receiving member 5 in the unacceptable state receives a water flow from the side opposite to the side where the fluid receiving port 21 exists. In this unacceptable state, the water inside the fluid receiving member 5 is discharged, and the portion of the fluid receiving member 5 opposite to the fluid receiving port 21 is flat. As shown in FIG. 10 (d), the fluid receiving port 21 in the unacceptable state is deformed to some extent by receiving a water flow, and the fluid receiving port 21 is smaller than that in the receivable state. Due to the elasticity of 51, the body receiving port 21 is not completely closed but maintains some opening. That is, the opening maintaining member 51 maintains the shape in which the fluid receiving port 21 in an unacceptable state is not sealed by its own elasticity. In the present embodiment, the opening maintaining member 51 is provided at the edge portion 50 that defines the fluid receiving port 21. However, if the fluid receiving port 21 is not sealed even in a state where the fluid receiving port 21 cannot be received, The opening maintaining member 51 may be provided at the position. Moreover, you may comprise the opening maintenance member 51 with metal springs.

本実施形態では、流体受入部材5が受入可能状態になると、開口維持部材51によって維持された開口に向かって流れる水がすぐに流体受入部材5の内部に流入する。また、開口維持部材51は自身の弾性により流体受入口21を拡大させるので、受入可能状態となった流体受入部材5は素早く確実に膨らむ。これにより、回転体3を効率よく回転させて流体発電装置1の発電効率を高めることができる。   In the present embodiment, when the fluid receiving member 5 is in an acceptable state, the water flowing toward the opening maintained by the opening maintaining member 51 immediately flows into the fluid receiving member 5. In addition, since the opening maintaining member 51 expands the fluid receiving port 21 by its own elasticity, the fluid receiving member 5 that has become ready to swell quickly and reliably. Thereby, the rotary body 3 can be rotated efficiently and the power generation efficiency of the fluid power generation device 1 can be increased.

本実施形態の流体発電装置からは、流体の流れによって回転する回転体を有し、該回転体の回転エネルギーを電気エネルギーに変換する流体発電装置において、前記回転体に設けられ、該回転体が回転することで、流体の流れの上流側に流体受入口が位置し内部に流体を受入可能な受入可能状態と、該流れの下流側に該流体受入口が位置し内部に流体を受入不能な受入不能状態との間で状態変化する2つの流体受入部材を備え、前記回転体は、前記受入可能状態の流体受入部材内に流体が流入することで回転エネルギーを生じるものであり、前記2つの流体受入部材は、一方の流体受入部材が前記受入可能状態にあるときに他方の流体受入部材は前記受入不能状態になり、該受入不能状態にあるときに前記流体受入口が縮小するものであり、該流体受入口が密閉されるこを防止する開口維持部材を有するものであることを特徴とする流体発電装置といった発明思想を導きだすことができる。また、この流体発電装置において、前記開口維持部材は、前記流体受入口を画定する縁部に設けられ、受入可能状態にある該流体受入口を拡大させる復元力を有する弾性体で構成されているものであってもよい。   The fluid power generation apparatus according to the present embodiment includes a rotating body that rotates by a fluid flow, and is provided in the rotating body in the fluid power generation apparatus that converts the rotational energy of the rotating body into electric energy. By rotating, the fluid receiving port is positioned upstream of the fluid flow and the fluid can be received inside, and the fluid receiving port is positioned downstream of the flow and cannot receive the fluid. Two fluid receiving members that change state between an unacceptable state and the rotating body generate rotational energy when fluid flows into the fluid receiving member in the acceptable state. The fluid receiving member is such that when one fluid receiving member is in the receivable state, the other fluid receiving member is in the unreceivable state, and when the fluid receiving member is in the unreceivable state, the fluid receiving port is reduced. , You can derive the invention idea, such as fluid power apparatus characterized in that with an opening maintaining member that prevents this fluid receiving opening is sealed. Further, in this fluid power generation device, the opening maintaining member is formed of an elastic body that is provided at an edge portion that defines the fluid receiving port and has a restoring force that expands the fluid receiving port in a receivable state. It may be a thing.

次に、図11(a)、図11(b)および図12に基づいて第5の実施形態を説明する。この第5の実施形態では、2つの浮遊体を前後方向に動作させることにより生じる推進力によって水の上を進む水上移動具について説明する。   Next, a fifth embodiment will be described based on FIG. 11A, FIG. 11B, and FIG. In the fifth embodiment, a description will be given of a water moving tool that moves on water by a propulsive force generated by operating two floating bodies in the front-rear direction.

図11(a)は、本実施形態に係る水上移動具60を示す側面図であり、図11(b)は、図11(a)を下側から見た下面図である。また、図12は、図11(b)のC−C断面である。この図11(a)および図11(b)では、浮遊体71を前後方向にずらした状態が示されている。図11(a)および図11(b)では図の左側が浮遊体71の前側となり、図の右側が浮遊体71の後ろ側となる。また、図11(a)および図11(b)における左方向を前方向と称し、右方向を後ろ方向と称することがある。   Fig.11 (a) is a side view which shows the water moving tool 60 which concerns on this embodiment, FIG.11 (b) is the bottom view which looked at Fig.11 (a) from the lower side. FIG. 12 is a CC cross section of FIG. FIGS. 11A and 11B show a state where the floating body 71 is shifted in the front-rear direction. 11A and 11B, the left side of the figure is the front side of the floating body 71, and the right side of the figure is the back side of the floating body 71. Further, the left direction in FIGS. 11A and 11B may be referred to as a front direction, and the right direction may be referred to as a rear direction.

本実施形態に係る水上移動具60は、2つの浮遊体71と、各浮遊体71の下面(着水面)に取り付けられた流体受入部材81とを備えている。浮遊体71は、発砲スチロールなどの浮力が得られる材質で構成されており、前側部分の下面が傾斜した船形状に形成されている。浮遊体71を構成する材料は、発砲スチロールでなくても浮遊性があればよく、例えば内部に空洞を有する樹脂製のものであってもよい。浮遊体71の前後方向の略中央部分には、上方が開口した凹部73が形成されている。この凹部73は、水上移動具60を使用する人が足を挿入する空間を形成する部分である。   The water moving tool 60 according to the present embodiment includes two floating bodies 71 and a fluid receiving member 81 attached to the lower surface (landing surface) of each floating body 71. The floating body 71 is made of a material capable of obtaining buoyancy, such as foamed polystyrene, and is formed in a ship shape in which the lower surface of the front side portion is inclined. The material constituting the floating body 71 is not limited to foamed polystyrene, but may be floating, for example, may be made of resin having a cavity inside. A concave portion 73 having an upper opening is formed in a substantially central portion of the floating body 71 in the front-rear direction. This recessed part 73 is a part which forms the space where the person who uses the water moving tool 60 inserts a foot | leg.

流体受入部材81は、柔軟性を有するビニール樹脂によってポケット状に構成されたものであり、後端部分に流体受入口84を有する。また、流体受入部材81の上面は浮遊体71の下面にネジなどで固定されている。流体受入部材81なお、流体受入部材81を完全な袋状に形成し、その袋状の一部分を浮遊体71に貼り付けても良い。図11(a)に示すように、この実施形態では、流体受入部材81は2つの浮遊体71に4つづつ設けているが、浮遊体71に設ける流体受入部材81の数はいくつでもよく、例えば1つづつでもよい。   The fluid receiving member 81 is configured in a pocket shape with a flexible vinyl resin, and has a fluid receiving port 84 at the rear end portion. The upper surface of the fluid receiving member 81 is fixed to the lower surface of the floating body 71 with screws or the like. Fluid receiving member 81 Note that the fluid receiving member 81 may be formed in a complete bag shape, and a part of the bag shape may be attached to the floating body 71. As shown in FIG. 11 (a), in this embodiment, four fluid receiving members 81 are provided on each of the two floating bodies 71, but any number of fluid receiving members 81 may be provided on the floating bodies 71. For example, it may be one by one.

図12に示すように、流体受入部材81の、流体受入口84を画定する縁部82の一部(以下、対向縁部821と称する)は、浮遊体71に対して接離自在に配置されている。その対向縁部821と浮遊体71との間隔が変化することで、流体受入口84の大きさも変化する。   As shown in FIG. 12, a part of the edge portion 82 (hereinafter, referred to as an opposite edge portion 821) that defines the fluid receiving port 84 of the fluid receiving member 81 is disposed so as to be able to contact with and separate from the floating body 71. ing. The size of the fluid receiving port 84 also changes as the distance between the facing edge 821 and the floating body 71 changes.

図12に示すように、流体受入部材81には、流体導入部材85が設けられている。この流体導入部材85は、剛性部材83と間隔保持部材87とから構成されている。剛性部材83は、流体受入部材81の、浮遊体71と対向する部分に溶着されている。この剛性部材83は、流体受入部材81に接着材などで貼り付けてもよい。剛性部材83は、流体受入部材5より剛性が高く水の抵抗を受けても変形しない樹脂製の板状部材であり、前端部分がヒンジ86により浮遊体71に結合されている。また、剛性部材83の後端部分は対向縁部821まで延在している。なお、剛性部材83として、金属製や木製の板状部材を用いてもよい。剛性部材83は、浮遊体71に対して接近する方向と離れる方向にヒンジ86を中心として回転可能となっている。なお、ヒンジ86は必ずしも設けなくてよいが、ヒンジ86を設けることで剛性部材83の回転動作を安定させることができる。   As shown in FIG. 12, the fluid receiving member 81 is provided with a fluid introducing member 85. The fluid introduction member 85 includes a rigid member 83 and a spacing member 87. The rigid member 83 is welded to a portion of the fluid receiving member 81 that faces the floating body 71. The rigid member 83 may be attached to the fluid receiving member 81 with an adhesive or the like. The rigid member 83 is a resin plate-like member that is higher in rigidity than the fluid receiving member 5 and does not deform even when subjected to water resistance, and has a front end portion coupled to the floating body 71 by a hinge 86. Further, the rear end portion of the rigid member 83 extends to the opposite edge portion 821. The rigid member 83 may be a metal or wooden plate member. The rigid member 83 is rotatable around the hinge 86 in a direction toward and away from the floating body 71. Although the hinge 86 is not necessarily provided, the rotation operation of the rigid member 83 can be stabilized by providing the hinge 86.

剛性部材83の上面には、流体導入部材85の回転を規制する間隔保持部材87が設けられている。流体導入部材85が浮遊体71に接近する方向に回転すると、対向縁部821が浮遊体71に接触する前に、間隔保持部材87が浮遊体71と接触して、その回転は停止する。従って、流体受入口84が完全に閉じることはなく、浮遊体71と対向縁部821とは所定量以上の間隔が常に保たれている。図12の二点鎖線は、剛性部材83が最も浮遊体側に接近した状態を示している。なお、間隔保持部材87は、流体受入部材81と浮遊体71の間であればどこに設けられていてもよく、例えば対向縁部821に設けてもよく、浮遊体71に設けてもよい。また、間隔保持部材87と剛性部材83を一体に形成してもよい。また、剛性部材83は、前後方向の長さが短いものであってもよい。   On the upper surface of the rigid member 83, an interval holding member 87 for restricting the rotation of the fluid introduction member 85 is provided. When the fluid introduction member 85 rotates in the direction approaching the floating body 71, the spacing member 87 contacts the floating body 71 before the opposing edge 821 contacts the floating body 71, and the rotation stops. Therefore, the fluid receiving port 84 is not completely closed, and the floating body 71 and the facing edge 821 are always kept at a predetermined distance or more. A two-dot chain line in FIG. 12 shows a state in which the rigid member 83 is closest to the floating body side. Note that the interval holding member 87 may be provided anywhere between the fluid receiving member 81 and the floating body 71, for example, may be provided on the facing edge portion 821, or may be provided on the floating body 71. Further, the spacing member 87 and the rigid member 83 may be integrally formed. Further, the rigid member 83 may have a short length in the front-rear direction.

浮遊体71を前方向に動かすと、図11(a)の左側の浮遊体71に示すように、流体受入部材81の流体受入口84は、流体受入部材81における反移動方向の端部に位置し、流体を受入不能な受入不能状態になる。これは、第1の実施形態において、流体受入口が水の流れにおける下流側に位置した状態と同様の状態である。また、浮遊体71を後ろ方向に動かすと、図11(a)の右側の浮遊体71に示すように、流体受入部材81の流体受入口84は、流体受入部材81における移動方向の端部に位置し、流体を受入可能な受入可能状態になる。これは、第1の実施形態において、流体受入口が水の流れにおける上流側に位置した状態と同様の状態である。   When the floating body 71 is moved forward, the fluid receiving port 84 of the fluid receiving member 81 is positioned at the end of the fluid receiving member 81 in the counter-movement direction, as shown in the floating body 71 on the left side of FIG. As a result, the fluid becomes unacceptable. This is the same state as the state in which the fluid receiving port is located on the downstream side in the water flow in the first embodiment. Further, when the floating body 71 is moved backward, as shown in the floating body 71 on the right side of FIG. 11A, the fluid receiving port 84 of the fluid receiving member 81 is located at the end of the fluid receiving member 81 in the moving direction. Positioned and ready to receive fluid. This is the same state as the state in which the fluid receiving port is located upstream in the flow of water in the first embodiment.

受入不能状態では、流体受入部材81内部の水が吐き出されて対向縁部821が浮遊体側に接近した図12に二点鎖線で示した状態となる。この状態では、流体受入部材81は扁平状となり、その流体受入部材81が浮遊体71の移動抵抗として殆ど影響しなくなる。ただし、この状態でも、対向縁部821は、浮遊体71から所定間隔が保たれているので、流体受入口84は所定間隔に応じた開口が維持される。流体受入部材81が受入不能状態となっている浮遊体71を後ろ方向に動かすと、流体受入部材81は受入可能状態となり、水は流体導入部材85の上面に導かれて流体受入口84から流体受入部材81の内部に流入して流体受入部材81が膨れる。膨れた流体受入部材81は水に対する大きな抵抗体となる。2つの浮遊体71のうちの一方を前方向に動かすと、他方の浮遊体71は、前方向に動かした浮遊体71による反力を受けて後ろ方向に移動しようとするが、受入可能状態となった流体受入部材81が水の抵抗を受けるため後ろ方向に殆ど移動しない。前方向に動かしている浮遊体71は、水の抵抗を殆ど受けないので効率的に前方向に進むことができる。   In the unacceptable state, water in the fluid receiving member 81 is discharged, and the opposite edge portion 821 approaches the floating body side as shown in FIG. In this state, the fluid receiving member 81 is flat, and the fluid receiving member 81 hardly affects the movement resistance of the floating body 71. However, even in this state, the opposed edge portion 821 is maintained at a predetermined interval from the floating body 71, so that the fluid receiving port 84 is maintained at an opening corresponding to the predetermined interval. When the floating body 71 in which the fluid receiving member 81 is in an unacceptable state is moved backward, the fluid receiving member 81 is in an acceptable state, and water is guided to the upper surface of the fluid introduction member 85 and fluid flows from the fluid receiving port 84. The fluid receiving member 81 expands by flowing into the receiving member 81. The swollen fluid receiving member 81 becomes a large resistor against water. When one of the two floating bodies 71 is moved in the forward direction, the other floating body 71 tries to move backward due to the reaction force of the floating body 71 moved in the forward direction. Since the fluid receiving member 81 is subjected to water resistance, it hardly moves backward. Since the floating body 71 moving in the forward direction hardly receives the resistance of water, it can efficiently advance in the forward direction.

この実施形態においては、流体導入部材85を設けているので、受入不能状態から受入可能状態となったときに流体受入部材81の内部に水が素早く流入する。流体導入部材85が存在しない場合には、受入可能状態となっても閉じた流体受入口84が水の相対的な流れにより浮遊体71に押し付けられてしまい、流体受入口84が閉じたままになってしまうことがある。本実施形態では、流体受入部材81が受入可能状態になると、流体導入部材85によって維持された開口に向かって流れる水は流体受入部材81の内部に導かれる。流体受入部材81の内部に導かれた水は、流体導入部材85を浮遊体71から離間する力として作用し、流体受入口84を拡大させる。   In this embodiment, since the fluid introduction member 85 is provided, water quickly flows into the fluid receiving member 81 when the receiving state is changed from the unacceptable state. When the fluid introduction member 85 is not present, the closed fluid receiving port 84 is pressed against the floating body 71 by the relative flow of water even if the fluid introducing member 85 is in the acceptable state, and the fluid receiving port 84 remains closed. It may become. In the present embodiment, when the fluid receiving member 81 is in a receivable state, the water flowing toward the opening maintained by the fluid introducing member 85 is guided into the fluid receiving member 81. The water guided to the inside of the fluid receiving member 81 acts as a force for separating the fluid introducing member 85 from the floating body 71 and enlarges the fluid receiving port 84.
