　特開２００６－１６９８５２号公報には、護岸に取り付けられた網によって、海面上を浮遊する浮遊物（ゴミ）を捕集する発明が開示されている。 Japanese Patent Laid-Open No. 2006-169852 discloses an invention in which floating objects (garbage) floating on the sea surface are collected using a net attached to a seawall.
　特開２００６－１６９８５２号公報の網は、護岸等に取り付ける必要がある。即ち、この網は、護岸から遠くはなれた海上で利用できない。さらに、この網は浮遊物の捕集機能に関して改善の余地がある。 The net disclosed in Japanese Unexamined Patent Publication No. 2006-169852 needs to be attached to a seawall, etc. That is, this net cannot be used at sea far from the seawall. Furthermore, there is room for improvement in the ability of this net to trap floating objects.
　本開示は、海及び湖の岸から離れた領域において使用可能であり、浮遊物を効果的に捕集できる浮遊物捕集装置を提供することを目的とする。 The present disclosure aims to provide a floating object collection device that can be used in areas away from the shores of oceans and lakes and can effectively collect floating objects.
　請求項１に記載の浮遊物捕集装置は、海又は湖の所定領域に浮かべられ、前記所定領域の平均水面と一緒に上下動する内枠と、前記内枠の外周側に位置しながら前記所定領域に浮かべられ、その上端が前記内枠の上端より上方に位置する状態で、前記所定領域の水面と一緒に上下動する外枠と、を備える。 The floating object collection device according to claim 1 includes an inner frame that is floated in a predetermined area of the sea or a lake and moves up and down with the average water surface of the predetermined area, and a floating object collector that is located on the outer peripheral side of the inner frame and The outer frame is floated in a predetermined area and moves up and down together with the water surface in the predetermined area with its upper end positioned above the upper end of the inner frame.
　請求項１に記載の発明では、海又は湖の所定領域に浮かんだ内枠と外枠は、波の力により上下方向に相対移動する。この際、内枠は所定領域の平均水面と一緒に上下動する一方で、外枠は、その上端が内枠の上端より上方に位置する状態で、所定領域の水面と一緒に上下動する。 In the invention according to claim 1, the inner frame and the outer frame floating in a predetermined area of the sea or lake are moved relative to each other in the vertical direction by the force of waves. At this time, the inner frame moves up and down together with the average water level in the predetermined area, while the outer frame moves up and down together with the water level in the predetermined area, with its upper end positioned above the upper end of the inner frame.
　なお、「内枠が平均水面と一緒に上下動する」とは、内枠が平均水面と完全に一緒に上下動すること、及び、内枠が平均水面と実質的に一緒に上下動すること、の両方の意味を含む。同様に、「外枠が所定領域の水面と一緒に上下動する」とは、外枠が所定領域の水面と完全に一緒に上下動すること、及び、外枠が所定領域の水面と実質的に一緒に上下動すること、の両方の意味を含む。 In addition, "the inner frame moves up and down together with the average water level" means that the inner frame moves up and down completely together with the average water level, and also means that the inner frame moves up and down substantially together with the average water level. , including both meanings. Similarly, "the outer frame moves up and down together with the water surface of the predetermined area" means that the outer frame moves up and down completely together with the water surface of the predetermined area, and that the outer frame substantially moves up and down with the water surface of the predetermined area. It includes both meanings of moving up and down together.
　波の影響により平均水面と外枠の上端との距離が小さくなったときに、波の力を受けた浮遊物が外枠の上端を乗り越えて内枠の内周側に移動することがある。即ち、浮遊物が浮遊物捕集装置によって捕集される。さらに、波の影響により、内枠の上端と外枠の上端との距離が大きくなると、捕集された浮遊物が、外枠の上端を乗り越えて外枠の外周側に移動するおそれが小さくなる。従って、請求項１に記載の浮遊物捕集装置は、浮遊物を効果的に捕集できる。 When the distance between the average water surface and the top of the outer frame becomes smaller due to the influence of waves, floating objects that receive the force of the waves may overcome the top of the outer frame and move toward the inner periphery of the inner frame. That is, floating matter is collected by the floating matter collection device. Furthermore, as the distance between the top edge of the inner frame and the top edge of the outer frame increases due to the influence of waves, the risk of the collected floating objects moving over the top edge of the outer frame to the outer periphery of the outer frame decreases. . Therefore, the floating matter collection device according to the first aspect can effectively collect floating matter.
　さらに請求項１に記載の浮遊物捕集装置は、護岸等に接続される必要がない。そのため、請求項１に記載の浮遊物捕集装置は、海及び湖の岸から離れた領域において使用可能である。 Furthermore, the floating object collection device according to claim 1 does not need to be connected to a seawall or the like. Therefore, the floating object trap according to claim 1 can be used in areas away from the shores of oceans and lakes.
　請求項２に記載の浮遊物捕集装置は、請求項１において、前記内枠が、前記所定領域の底から離れた位置に位置する錘を備える。 In the floating object collection device according to claim 2, in claim 1, the inner frame includes a weight located at a position away from the bottom of the predetermined area.
　請求項３に記載の浮遊物捕集装置は、請求項１又は請求項２において、前記内枠と前記外枠の一方に設けられ、前記内枠と前記外枠の他方に対して回転しながら接触可能なローラを備える。 The floating matter collection device according to claim 3 is the floating matter collection device according to claim 1 or 2, which is provided on one of the inner frame and the outer frame, and is configured to rotate with respect to the other of the inner frame and the outer frame. Equipped with contactable rollers.
　請求項４に記載の浮遊物捕集装置は、請求項１又は請求項２において、前記内枠の内周側に位置し、前記内枠に支持された網を備える。 A floating object collection device according to a fourth aspect of the invention includes a net located on an inner peripheral side of the inner frame and supported by the inner frame.

The net 72 made of a flexible material is formed into a bag shape with only the upper end open. The upper edge of the net 72 is fixed to the ring member 71. The ring member 71 is attachable to and detachable from the horizontal reinforcing member 42. When the ring member 71 is attached to the horizontal reinforcing member 42, the net 72 is located in the space on the inner peripheral side of the inner frame 40, as shown in FIGS. 6 and 7. Further, as shown in FIG. 2, one end of the plurality of connecting members 73 is fixed to the ring member 71, and the other end of each connecting member 73 is fixed to the hook portion 74. The hook portion 74 includes an annular portion 75 .
　次に、実施形態の作用及び効果を説明する。 Next, the functions and effects of the embodiment will be explained.
　例えば浮遊物捕集装置１０は、図６及び図７に示されるように海８０の岸（図示省略）から遠く離れた所定領域８１に設置される。上述のように外枠１５の比重は海水の比重より小さい第１比重であり、内枠４０の比重は海水の比重より小さい第２比重である。そのため浮遊物捕集装置１０を所定領域８１に設置すると、各容器３０、６０が発生する浮力によって、外枠１５及び内枠４０は所定領域８１に対して浮かぶ。より詳細には、外枠１５の上端の水面８２からの上方への突出量Ｐｈ１は、波８３の高さに拘わらずほぼ一定である。即ち、外枠１５は、実質的に波８３（水面８２）と一緒に上下動する。一方、内枠４０は、実質的に所定領域８１の平均水面８２Ａ（図６及び図７の仮想線参照）と一緒に上下動する。これは、重量が大きく且つ海８０の底８０Ｂから上方に離れた錘６５が、緊張状態にある連結部材６４を介して内枠４０に力を及ぼしているためである。この錘６５の働きにより、平均水面８２Ａと錘６５の下面との間の上下方向の距離Ｄｐが、波８３の高さに拘わらず略一定に維持される。即ち、内枠４０の上端の平均水面８２Ａからの上方への突出量Ｐｈ２が、波８３の高さに拘わらずほぼ一定に維持される。本明細書において「平均水面」とは、その領域に含まれる全ての波８３の高さの平均値を通る仮想面のことである。 For example, the floating object collection device 10 is installed in a predetermined area 81 far away from the shore of the sea 80 (not shown), as shown in FIGS. 6 and 7. As described above, the specific gravity of the outer frame 15 is the first specific gravity smaller than the specific gravity of seawater, and the specific gravity of the inner frame 40 is the second specific gravity smaller than the specific gravity of seawater. Therefore, when the floating matter collection device 10 is installed in the predetermined area 81, the outer frame 15 and the inner frame 40 float with respect to the predetermined area 81 due to the buoyant force generated by each container 30, 60. More specifically, the upward protrusion amount Ph1 of the upper end of the outer frame 15 from the water surface 82 is substantially constant regardless of the height of the wave 83. That is, the outer frame 15 substantially moves up and down together with the waves 83 (water surface 82). On the other hand, the inner frame 40 moves up and down substantially together with the average water level 82A of the predetermined area 81 (see imaginary lines in FIGS. 6 and 7). This is because the weight 65, which has a large weight and is located upwardly from the bottom 80B of the sea 80, exerts a force on the inner frame 40 via the connecting member 64 which is in tension. Due to the function of this weight 65, the distance Dp in the vertical direction between the average water surface 82A and the lower surface of the weight 65 is maintained substantially constant regardless of the height of the wave 83. That is, the upward protrusion amount Ph2 of the upper end of the inner frame 40 from the average water surface 82A is maintained substantially constant regardless of the height of the wave 83. In this specification, the term "average water surface" refers to a virtual surface passing through the average height of all waves 83 included in the area.
　例えば、突出量Ｐｈ１は４０～６０ｃｍの範囲で設定される。また、突出量Ｐｈ２は、例えば外枠１５の上端と内枠４０の上端との上下方向の距離が、２０～３０ｃｍとなるように設定される。突出量Ｐｈ１の大きさは、容器３０の数を変更することにより調整可能である。突出量Ｐｈ２の大きさは、錘６５の質量及び容器６０の数を変更することにより調整可能である。波８３の高さが大きいときは、突出量Ｐｈ１、Ｐｈ２を、波８３の高さが小さいときより大きくするのが好ましい。 For example, the protrusion amount Ph1 is set in a range of 40 to 60 cm. Further, the protrusion amount Ph2 is set such that, for example, the distance in the vertical direction between the upper end of the outer frame 15 and the upper end of the inner frame 40 is 20 to 30 cm. The magnitude of the protrusion amount Ph1 can be adjusted by changing the number of containers 30. The magnitude of the protrusion amount Ph2 can be adjusted by changing the mass of the weight 65 and the number of containers 60. When the height of the waves 83 is large, it is preferable to make the protrusion amounts Ph1 and Ph2 larger than when the height of the waves 83 is small.
　ここで図６に示されるように、所定の大きさの波８３が発生している所定領域８１に浮遊物捕集装置１０が浮かび、且つ、水面８２に２つの浮遊物８５、８６が浮かんでいる場合を想定する。このとき波８３（水面８２）が図６の状態にあり、外枠１５の上端は図６に示された位置に位置する。一方、内枠４０の上端は図６に示された位置にある。このときの外枠１５の上端と内枠４０の上端との上下方向の距離はＤ１である。このときの平均水面８２Ａから外枠１５の上端までの距離Ｈ１が長いので、波８３の力を受けた浮遊物８５、８６が外枠１５の上端を乗り越えて、外枠１５の内周側へ移動する可能性は低い。 Here, as shown in FIG. 6, the floating object collection device 10 floats in a predetermined area 81 where waves 83 of a predetermined size are generated, and two floating objects 85 and 86 are floating on the water surface 82. Assume that there is. At this time, the wave 83 (water surface 82) is in the state shown in FIG. 6, and the upper end of the outer frame 15 is located at the position shown in FIG. On the other hand, the upper end of the inner frame 40 is at the position shown in FIG. The distance in the vertical direction between the upper end of the outer frame 15 and the upper end of the inner frame 40 at this time is D1. Since the distance H1 from the average water surface 82A to the upper end of the outer frame 15 at this time is long, the floating objects 85 and 86 that have received the force of the waves 83 overcome the upper end of the outer frame 15 and move toward the inner circumferential side of the outer frame 15. Less likely to move.
　波８３が図７に示された状態になると、外枠１５の上端は図７に示された位置に位置し、内枠４０の上端は図７に示された位置に位置する。このときの外枠１５の上端と内枠４０の上端との上下方向の距離は、上記距離Ｄ１より短い距離Ｄ２である。さらに、このときの平均水面８２Ａから外枠１５の上端までの距離Ｈ２は、距離Ｈ１より短い。そのため、例えば、このタイミングで所定領域８１において大きな波（図示省略）が発生すると、この波によって浮遊物８５、８６が外枠１５の上端を乗り越えて、内枠４０の上端及びリング部材７１の内周側へ移動し易い。即ち、浮遊物８５、８６が網７２によって捕集され易い。 When the wave 83 is in the state shown in FIG. 7, the upper end of the outer frame 15 is located at the position shown in FIG. 7, and the upper end of the inner frame 40 is located at the position shown in FIG. The distance in the vertical direction between the upper end of the outer frame 15 and the upper end of the inner frame 40 at this time is a distance D2 shorter than the distance D1. Furthermore, the distance H2 from the average water surface 82A to the upper end of the outer frame 15 at this time is shorter than the distance H1. Therefore, for example, if a large wave (not shown) occurs in the predetermined area 81 at this timing, the floating objects 85 and 86 will go over the upper end of the outer frame 15 and the upper end of the inner frame 40 and inside the ring member 71. Easy to move towards the periphery. That is, the floating objects 85 and 86 are easily collected by the net 72.
　さらに、この直後に所定領域８１が図６に示された状態に戻ると、外枠１５及び内枠４０の上下方向位置が図６に示された位置になる。即ち、外枠１５の上端と内枠４０の上端との上下方向の距離が再び距離Ｄ１になる。そのため、網７２によって捕集された浮遊物８５、８６が、外枠１５の上端を乗り越えて、外枠１５の外周側に移動するおそれは小さい。 Furthermore, immediately after this, when the predetermined area 81 returns to the state shown in FIG. 6, the vertical positions of the outer frame 15 and the inner frame 40 become the positions shown in FIG. That is, the distance in the vertical direction between the upper end of the outer frame 15 and the upper end of the inner frame 40 becomes the distance D1 again. Therefore, there is little possibility that the floating objects 85 and 86 collected by the net 72 will climb over the upper end of the outer frame 15 and move toward the outer periphery of the outer frame 15.
　このように本実施形態の浮遊物捕集装置１０は、海８０にある浮遊物を効果的に捕集できる。さらに浮遊物捕集装置１０は、護岸等に接続される必要がないので、海８０の岸から離れた領域（所定領域８１）において使用可能である。さらに海８０の潮の干満によって底８０Ｂから水面８２（平均水面８２Ａ）までの距離が変化しても、浮遊物捕集装置１０は上記効果を発揮可能である。 In this way, the floating object collection device 10 of this embodiment can effectively collect floating objects in the sea 80. Furthermore, since the floating object collection device 10 does not need to be connected to a seawall or the like, it can be used in an area (predetermined area 81) away from the shore of the sea 80. Furthermore, even if the distance from the bottom 80B to the water surface 82 (average water surface 82A) changes due to the ebb and flow of the sea 80, the floating object collection device 10 can exhibit the above effects.
　さらに、外枠１５と内枠４０が上下方向に相対移動するときに、少なくとも一つのローラ５１が縦補強部材２０の基板部２１に回転しながら接触する。換言すると、外枠１５と内枠４０が上下方向に相対移動するときに、縦補強部材２０が内枠４０に接触しない。そのため、外枠１５と内枠４０が繰り返し上下動しても、外枠１５と内枠４０は損傷し難い。 Further, when the outer frame 15 and the inner frame 40 move relative to each other in the vertical direction, at least one roller 51 comes into contact with the base plate 21 of the vertical reinforcing member 20 while rotating. In other words, when the outer frame 15 and the inner frame 40 move relative to each other in the vertical direction, the vertical reinforcing member 20 does not come into contact with the inner frame 40. Therefore, even if the outer frame 15 and the inner frame 40 repeatedly move up and down, the outer frame 15 and the inner frame 40 are not easily damaged.
　さらに網部材７０が引掛け部７４を備える。そのため、例えば空中を飛行可能なドローン（図示省略）を水面８２へ接近させることにより、ドローンに設けられたフックを環状部７５に引っ掛けることが可能である。さらに、その後にドローンを上方へ移動させると、網部材７０が内枠４０から分離する。この状態でドローンを所定の浮遊物回収場まで飛行させることにより、網７２によって捕集された浮遊物を浮遊物回収場まで移送できる。 Further, the net member 70 includes a hook portion 74. Therefore, for example, by bringing a drone (not shown) that can fly in the air close to the water surface 82, it is possible to hook a hook provided on the drone onto the annular portion 75. Furthermore, when the drone is subsequently moved upward, the net member 70 is separated from the inner frame 40. By flying the drone to a predetermined floating object collection site in this state, the floating objects collected by the net 72 can be transported to the floating object collection site.
　以上、本開示を実施形態に基づいて説明したが、本開示はその要旨を逸脱しない範囲内において、適宜設計変更可能である。 Although the present disclosure has been described above based on the embodiments, the design of the present disclosure can be modified as appropriate without departing from the gist thereof.
　例えば、図８に示された第１変形例の態様で浮遊物捕集装置１０Ａを構成してもよい。この浮遊物捕集装置１０Ａの内枠４０は、円筒状部材４１Ａ、複数の横補強部材４２、４３、４４、４５、複数の縦補強部材４６、複数の回転軸５０、複数のローラ５１、複数のブラケット５４、複数の容器６０及び錘６５を備える。この内枠４０の比重も第２比重である。なお、便宜上、図８では横補強部材４２、４３、４４、４５、縦補強部材４６、回転軸５０、ローラ５１、及びブラケット５４及び容器６０の図示が省略されている。 For example, the floating object collection device 10A may be configured in the form of the first modification shown in FIG. 8. The inner frame 40 of this floating object collection device 10A includes a cylindrical member 41A, a plurality of horizontal reinforcing members 42, 43, 44, 45, a plurality of vertical reinforcing members 46, a plurality of rotating shafts 50, a plurality of rollers 51, a plurality of bracket 54, a plurality of containers 60, and a weight 65. The specific gravity of this inner frame 40 is also the second specific gravity. For convenience, illustration of the horizontal reinforcing members 42, 43, 44, 45, the vertical reinforcing member 46, the rotating shaft 50, the roller 51, the bracket 54, and the container 60 is omitted in FIG.
　第１変形例の円筒状部材４１Ａの上下長は、上記実施形態の円筒状部材４１の上下長より大きい。さらに円筒状部材４１Ａの底部に錘６５が固定されている。そのため第１変形例においても、錘６５の働きにより、平均水面８２Ａと錘６５の下面との間の上下方向の距離Ｄｐが、波８３の高さに拘わらず略一定に維持される。即ち、内枠４０の上端の平均水面８２Ａからの上方への突出量Ｐｈ２が、波８３の高さに拘わらずほぼ一定に維持される。そのため第１変形例の浮遊物捕集装置１０Ａも、上記実施形態の浮遊物捕集装置１０と同様の作用効果を発揮可能である。 The vertical length of the cylindrical member 41A of the first modification is larger than the vertical length of the cylindrical member 41 of the above embodiment. Further, a weight 65 is fixed to the bottom of the cylindrical member 41A. Therefore, in the first modification as well, due to the function of the weight 65, the distance Dp in the vertical direction between the average water surface 82A and the lower surface of the weight 65 is maintained substantially constant regardless of the height of the wave 83. That is, the upward protrusion amount Ph2 of the upper end of the inner frame 40 from the average water surface 82A is maintained substantially constant regardless of the height of the wave 83. Therefore, the floating matter collection device 10A of the first modification can also exhibit the same effects as the floating matter collection device 10 of the above embodiment.
　また図９に示された第２変形例の態様で浮遊物捕集装置１０Ｂを構成してもよい。この浮遊物捕集装置１０Ｂの外枠１５は、円筒状部材１６の上端部の内周側に位置し、円筒状部材１６と同軸をなす、円筒形状のスライド部材３５を備える。スライド部材３５は円筒状部材１６に対して上下方向にスライド可能である。さらに固定手段（図示省略）により、スライド部材３５を円筒状部材１６に対して任意の上下方向位置で固定可能である。この外枠１５の比重も第１比重である。 Furthermore, the floating object collection device 10B may be configured in the form of the second modification shown in FIG. 9. The outer frame 15 of the floating object collection device 10B includes a cylindrical slide member 35 located on the inner peripheral side of the upper end of the cylindrical member 16 and coaxial with the cylindrical member 16. The slide member 35 is slidable in the vertical direction with respect to the cylindrical member 16. Furthermore, the slide member 35 can be fixed to the cylindrical member 16 at any vertical position by a fixing means (not shown). The specific gravity of this outer frame 15 is also the first specific gravity.
　例えば、スライド部材３５を仮想線で示された位置へスライドさせた後に上記固定手段により、スライド部材３５と円筒状部材１６を固定した場合を想定する。この場合は、浮遊物捕集装置１０Ｂがスライド部材３５を具備しない場合と比べて、平均水面８２Ａから外枠１５の上端までの距離Ｈ３が大きくなる。そのため、網７２によって捕集された浮遊物８５、８６が、外枠１５の上端を乗り越えて、外枠１５の外周側に移動するおそれがより小さくなる。 For example, assume that the slide member 35 and the cylindrical member 16 are fixed by the fixing means after the slide member 35 is slid to the position indicated by the imaginary line. In this case, the distance H3 from the average water surface 82A to the upper end of the outer frame 15 becomes larger than when the floating object collection device 10B does not include the slide member 35. Therefore, the possibility that the floating objects 85 and 86 collected by the net 72 will climb over the upper end of the outer frame 15 and move toward the outer periphery of the outer frame 15 is reduced.
　また図１０及び図１１に示された第３変形例の態様で浮遊物捕集装置１０Ｃを構成してもよい。この浮遊物捕集装置１０Ｃは、外枠９０、内枠９２、連結部材６４及び錘６５を備える。 Furthermore, the floating matter collection device 10C may be configured in the third modification shown in FIGS. 10 and 11. This floating object collection device 10C includes an outer frame 90, an inner frame 92, a connecting member 64, and a weight 65.
　外枠９０は、内部に気体（例えば空気）が充填された袋状の環状部材である第１浮遊体９１を備える。第１浮遊体９１は、例えば樹脂材料により構成される。外枠９０の比重も第１比重である。 The outer frame 90 includes a first floating body 91 that is a bag-shaped annular member filled with gas (for example, air). The first floating body 91 is made of, for example, a resin material. The specific gravity of the outer frame 90 is also the first specific gravity.
　内枠９２は、内部に気体（例えば空気）が充填された袋状の環状部材である第２浮遊体９３、連結部材６４及び錘６５を備える。第２浮遊体９３は、例えば樹脂材料により構成される。第２浮遊体９３の下端部には２本の連結部材６４の上端部がそれぞれ固定され、各連結部材６４の下端部に錘６５が固定されている。内枠９２の比重も第２比重である。 The inner frame 92 includes a second floating body 93, which is a bag-shaped annular member filled with gas (for example, air), a connecting member 64, and a weight 65. The second floating body 93 is made of, for example, a resin material. The upper ends of two connecting members 64 are fixed to the lower end of the second floating body 93, and a weight 65 is fixed to the lower end of each connecting member 64. The specific gravity of the inner frame 92 is also the second specific gravity.
　図１０に示されたように、第１浮遊体９１の内径が第２浮遊体９３の外径より大きい。図１１に示されたように、第１浮遊体９１及び第２浮遊体９３は、第１浮遊体９１の内周側に第２浮遊体９３が位置する状態で、海８０の所定領域８１に浮かべられる。 As shown in FIG. 10, the inner diameter of the first floating body 91 is larger than the outer diameter of the second floating body 93. As shown in FIG. 11, the first floating body 91 and the second floating body 93 are placed in a predetermined area 81 of the sea 80, with the second floating body 93 located on the inner peripheral side of the first floating body 91. Float.
　図１１に示されたように、第１浮遊体９１（外枠９０）の上端の水面８２からの上方への突出量Ｐｈ１は、波８３の高さに拘わらずほぼ一定である。即ち、第１浮遊体９１は、実質的に波８３（水面８２）と一緒に上下動する。一方、第２浮遊体９３（内枠９２）は、錘６５の働きにより、実質的に所定領域８１の平均水面８２Ａと一緒に上下動する。平均水面８２Ａと錘６５の下面との間の上下方向の距離Ｄｐは、波８３の高さに拘わらず略一定に維持される。そのため、第２浮遊体９３の上端の平均水面８２Ａからの上方への突出量Ｐｈ２は、波８３の高さに拘わらずほぼ一定に維持される。 As shown in FIG. 11, the upward protrusion amount Ph1 of the upper end of the first floating body 91 (outer frame 90) from the water surface 82 is approximately constant regardless of the height of the wave 83. That is, the first floating body 91 moves up and down substantially together with the waves 83 (water surface 82). On the other hand, the second floating body 93 (inner frame 92) moves up and down substantially together with the average water surface 82A of the predetermined area 81 due to the function of the weight 65. The vertical distance Dp between the average water surface 82A and the lower surface of the weight 65 is maintained substantially constant regardless of the height of the wave 83. Therefore, the upward protrusion amount Ph2 of the upper end of the second floating body 93 from the average water surface 82A is maintained substantially constant regardless of the height of the wave 83.
　第１浮遊体９１の外周側において水面８２に浮かんでいた浮遊物８５、８６が波の影響により、第１浮遊体９１の上端部及び第２浮遊体９３の上端部を乗り越えて第２浮遊体９３の内周側に移動すると、浮遊物８５、８６は第２浮遊体９３の内周側において水面８２に浮かぶ。このようにして第２浮遊体９３の内周側に集められた浮遊物８５、８６は、例えば所定領域８１に浮かぶ船舶（図示省略）に設置された吸引装置（図示省略）により、当該船舶のデッキ上に集めることが可能である。 Due to the influence of the waves, the floating objects 85 and 86 floating on the water surface 82 on the outer peripheral side of the first floating object 91 cross over the upper end of the first floating object 91 and the upper end of the second floating object 93 and move to the second floating object. When the floating objects 85 and 86 move toward the inner circumferential side of the second floating body 93, they float on the water surface 82 on the inner circumferential side of the second floating body 93. The floating objects 85 and 86 collected on the inner circumferential side of the second floating body 93 in this way are removed by a suction device (not shown) installed on a ship (not shown) floating in the predetermined area 81, for example. It is possible to collect them on the deck.
　このように第３変形例の浮遊物捕集装置１０Ｃも、上記実施形態の浮遊物捕集装置１０と同様の作用効果を発揮可能である。さらに第３変形例の浮遊物捕集装置１０Ｃは網部材７０に相当する部材を具備しないので、構成が簡単である。 In this way, the floating object collecting device 10C of the third modification can also exhibit the same effects as the floating object collecting device 10 of the above embodiment. Furthermore, since the floating object collecting device 10C of the third modification does not include a member corresponding to the net member 70, the structure is simple.
　浮遊物捕集装置１０、１０Ａ、１０Ｂ、１０Ｃが使用される場所は、波が発生する湖であってもよい。この場合の第１比重及び第２比重は湖の比重より小さい。 The place where the floating object collection devices 10, 10A, 10B, and 10C are used may be a lake where waves are generated. The first specific gravity and second specific gravity in this case are smaller than the specific gravity of the lake.
　一部のブラケット２５にのみ容器３０を取り付けてもよい。同様に、一部のブラケット５４にのみ容器６０を取り付けてもよい。 The containers 30 may be attached to only some of the brackets 25. Similarly, the containers 60 may be attached to only some of the brackets 54.
　外枠１５が海又は湖に浮かぶのであれば、外枠１５はブラケット２５及び容器３０を備えなくてもよい。 If the outer frame 15 floats on the sea or lake, the outer frame 15 does not need to include the bracket 25 and the container 30.
　内枠４０が海又は湖に浮かぶのであれば、内枠４０はブラケット５４及び容器６０を備えなくてもよい。 If the inner frame 40 floats on the sea or lake, the inner frame 40 does not need to include the bracket 54 and the container 60.
　内枠４０の比重（第２比重）が外枠１５の比重（第１比重）より大きく、且つ、突出量Ｐｈ２が波８３の高さに拘わらずほぼ一定に維持されるのであれば、内枠４０、９２は錘６５を備えなくてもよい。 If the specific gravity (second specific gravity) of the inner frame 40 is greater than the specific gravity (first specific gravity) of the outer frame 15 and the protrusion amount Ph2 is maintained almost constant regardless of the height of the wave 83, the inner frame 40 and 92 may not include the weight 65.
　外枠１５の機械的強度を確保できるのであれば、外枠１５は横補強部材１７、１８、１９を備えなくてもよい。 As long as the mechanical strength of the outer frame 15 can be ensured, the outer frame 15 does not need to include the horizontal reinforcing members 17, 18, and 19.
　内枠４０の械的強度を確保できるのであれば、内枠４０は横補強部材４２、４３、４４、４５を備えなくてもよい。 As long as the mechanical strength of the inner frame 40 can be ensured, the inner frame 40 does not need to include the horizontal reinforcing members 42, 43, 44, and 45.
　外枠１５にローラ５１を回転可能に設けて、このローラ５１を内枠４０の外周面に接触させてもよい。 A roller 51 may be rotatably provided on the outer frame 15 and brought into contact with the outer peripheral surface of the inner frame 40.
　外枠１５が、円筒状部材１６の代わりに、断面形状が多角形又は略多角形をなす筒状部材を備えてもよい。 Instead of the cylindrical member 16, the outer frame 15 may include a cylindrical member having a polygonal or substantially polygonal cross-sectional shape.
　内枠４０が、円筒状部材４１の代わりに、断面形状が多角形又は略多角形をなす筒状部材を備えてもよい。 Instead of the cylindrical member 41, the inner frame 40 may include a cylindrical member having a polygonal or substantially polygonal cross-sectional shape.
　外枠１５の円筒状部材１６又は上記筒状部材に、多数の貫通孔が形成されてもよい。同様に、内枠４０円筒状部材４１又は上記筒状部材に、多数の貫通孔が形成されてもよい。 A large number of through holes may be formed in the cylindrical member 16 of the outer frame 15 or the above-mentioned cylindrical member. Similarly, a large number of through holes may be formed in the inner frame 40 cylindrical member 41 or the above-mentioned cylindrical member.
　浮遊物捕集装置１０、１０Ａ、１０Ｂから網部材７０を省略してもよい。この場合は、内枠４０の内周側において捕集された浮遊物を、吸引装置（図示省略）又は容器（図示省略）を利用して回収してもよい。なお、この容器は、多数の小径の貫通孔が形成されたものであってもよい。 The net member 70 may be omitted from the floating object collection devices 10, 10A, and 10B. In this case, the floating matter collected on the inner peripheral side of the inner frame 40 may be collected using a suction device (not shown) or a container (not shown). Note that this container may be formed with a large number of small-diameter through holes.
