【0001】
【発明の属する技術分野】
本発明は、風車等を海上や水上に設置するために、海上や水上に浮かぶ台、浮台に関する。
【0002】
【従来技術】
従来、風車等を海上や水上に浮かぶ浮台に設置する場合、特開2000−272581号に開示されているように、複数の浮体を周囲に設けた浮台に風車が設置されていた。
【特許文献】特開2000−272581号
【0003】
【発明が解決しようとする課題】
しかし、このような設備は大掛かりなものであると共に、各浮体を支持して結合する必要があるので構造が複雑になる。よって、部品加工や組立てに時間が掛かるので製作して設置するためには多くの費用が掛かる。従って、経済的に豊かではない離島や山間部等の過疎地において設置する場合、国や都道府県等の援助がないと設置することができない。
【0004】
又、このような複雑な構造においては、組立分解が不可能であるので、容易に設置場所を移動することができない。もし組立分解が可能であったとしても設備が大掛かりなものであるので、設置場所の移動に時間と労力が掛かる。
【0005】
そこで、本発明は上記課題を解決するためのもので、多くの費用を掛けずに、簡単な構造により組立分解を容易にすることで設置場所の移動が容易にできる風車等を海上や水上に設置するための浮台を提供することを目的とする。
【0006】
【課題を解決しようとする手段】
上記目的を達成するために、本発明は以下の構成とされている。
本発明の請求項1は、互いに離して並行に配置した複数の菅材と、この菅材が貫通する孔を面部に、又は凹溝を周辺部に有する板状の固定板と、この菅材を緊縛して固定板に固定する線形材料とで形成されたトラス構造の空間にフロートを挿入したことを特徴とする浮台である。
【0007】
本発明の請求項2は、固定板の上部を延長して他の浮台と連結する連結部を形成し、連結具によって他の浮体と連結することを特徴とする請求項1に記載の浮台である。
【0008】
本発明の請求項3は、菅材の一部を軸方向に固定板の厚みで欠如部を形成し、この欠如部に固定板の上部を挿入し、欠如部の対辺の菅材の内面に固定板の上端を突き当てるように線形材料で緊縛したことを特徴とする請求項2に記載の浮台である。
【0009】
本発明の請求項4は、固定板の間に平板を設け、この平板の下部にペットボトルの口部を保持する孔を設けた短冊状の取付板を取付け、この孔にペットボトルの口部を挿入してフロートを形成したことを特徴とする請求項1乃至3に記載の浮台である。
【0010】
本発明の請求項5は、複数のフロートをネットで包み込んで一体とした浮体を荷重位置に対応して配置し、この浮体を菅材により連結したことを特徴とする浮台である。
【0011】
【実施例】
最初にフロートにペットボトルを使用するタイプの浮台の実施形態(イ)について図1から図5を用いて説明する。図1は浮台1の正面図、図2は浮台1の側面図、図3は浮台1の平面図、図4は浮台1のA−A断面図、図5は浮台1のB−B断面図である。
【0012】
浮台1は並行に配置された複数の菅材2と、その菅材2を一定間隔L1で保持する固定板3とで形成されたトラス構造の空間に複数のペットボトル4が挿入されて形成される。
【0013】
初めにトラス構造について説明する。固定板3は、図2、4に示すように平板5、6の両端に複数のホゾ19を設け、固定板3の中央部に複数のホゾ溝20を設け、ホゾ構造により平板5、6の両端に直角に固定される。複数の菅材2は、固定板3に設けられた孔7又は凹溝8に挿入されて、複数のペットボトル4の周囲に並行に配置される。菅材2は、図2、4、5に示すように固定板3の側面で針金等の線形材料9により緊縛して固定板3に固定される。線形材料9による菅材2の具体的な緊縛方法は、図2、4に示すように菅材2をペットボトル4の下部、側部、左上部と右上部に分けて結束される。下部は2本の菅材2が1つの線形材料9で結束される。側部は左右側部に設けられた4本の菅材2が1つの線形材料9で結束される。左上部、右上部の2本の菅材2は、それぞれ固定板3の中央に設けた凸部10と線形材料9で三角形状に結束される。この様にして菅材2と固定板3とのトラス構造は形成される。
【0014】
次にペットボトル4の取付構造について説明する。ペットボトル4の口部は、図5に示すように短冊状の取付板11の孔12に挿入され、この取付板11は固定板3の間L1に設けられた平板5の下部に木ねじ等により取付けられる。ペットボトル4の底部は固定板3の間L1に設けられた平板6に支えられる。これにより複数のペットボトル4群は菅材2と固定板3とのトラス構造の空間にフロートとして配置される。そして、図1、5で示すように紐で簾状に連結した半割の竹13で、ペットボトル4群を覆うように浮台1の底部、側部の下半分が覆われる。
【0015】
尚、本実施形態においては、図1〜5に示すように1つの浮台1は、10本の約3mの菅材2、4個の固定板3、各3個の平板5、平板6、24個の取付板11と144個のペットボトル4で形成される。菅材2は竹であり、固定板3、平板5、平板6と取付板11はコンパネ(木製)であり、線形材料9はステンレス製の針金である。
【0016】
次に浮台1を連結具14により連結する構造について図4、5を用いて説明する。本実施形態の連結具14としては菅材が用いられる。連結具(菅材)14の一端の外周に設けられた欠如部15に固定板3の上端を挿入される。固定板3の長孔16に挿入された針金等の線形部材17によって、固定板3の上端が欠如部15の対辺の連結具(菅材)14の内面18に突き当てるように連結具(菅材)14が緊縛される。これより、連結具(菅材)14の一端が浮台1の固定板3の上端に固定される。同様の固定方法で連結具(菅材)14の他端を他の浮台1に固定して浮台1と浮台1とが連結される。又、浮台1を菅材2の軸心方向に連結する方法は、固定板3の菅材2が貫通する孔7、凹溝8を小判型の長孔にして、その各長孔に連結する浮台1の各菅材2を挿入して緊縛することにより浮台1と浮台1とが菅材2の軸方向に連結される。
【0017】
上記実施形態(イ)においては、1つの浮台1に144個の2リットルのペットボトル4を有するので、ペットボトル4の約6割が水に浸かると、1つの浮台1で約170kgの浮力を有する。この浮台1を連結具14で横方向に3台、管材2の軸方向に2台の計6台を連結すると約1トン(170kg×6)の浮力を得ることができるので、6台の浮台1を連結した大きな浮台には約1トンの設置物を置くことが可能である。よって、複数の浮台1を連結することで風車を設置できる大きな浮台を形成することができる。従って、海上や水上を吹く風を利用して風車を回転させることで、エネルギー、動力を得ることができる。このエネルギー、動力を利用して、ダイナモ(発電機)を回転させて電力を得ることができる。又、ふいごを動かして水中に空気を送って泡を形成することでエアーレーションとして使用できる。更に、浮台1の水中側にフォルト・シュナイダープロペラ等のスクリューを突出させて設け、このスクリューを回転させて浮台1の推進力としても利用できる。これにより、浮台1をヨットしても使用できる。このとき、ペットボトル4群の側部と下部は半割の竹13で覆われているので外形が滑らかになって、水の抵抗が小さくなるので、ヨットがスムーズに走ることができる。又、風車を設けずに単に舟として渡し舟に使用したり、家を設置して浮島として使用することもできる。
【0018】
海上や水上の風力は地上の風力に比べて大きいので、地上に設けた風車より海上や水上に設けた風車の方が大きな電力を得ることができる。又、海上や水上の方が陸上に比べて土地の買収等のいろいろな諸条件の制約が少ない。
【0019】
エアーレーションやヨット(浮台1)の推進力は風車により得られた動力をその場で利用するので動力を効率よく使用することができる。又、浮台1の外部からエネルギー、動力を加えずにエアーレーションのふいごやヨット(浮台1)のプロペラを稼動させることができる。
【0020】
上記実施形態(イ)においては、菅材2と固定板3とで形成したトラス構造の空間にフロートとなるペットボトル4を挿入した浮台1であるので、船のように枠組みを形成する必要がなく、又複数のフロートを連結するための構造も必要ない。又、菅材2と固定板3とのトラス構造の形成には溶接やボルト等を使用しないで針金等の線形材料9で組立てられているので分解組立が容易である。よって、浮台1の設置場所の移動が容易にできる。更にトラス構造であるので強度がある。
【0021】
浮台1に連結部が形成されて他の浮台1と連結具14で連結することができるので、複数の浮台1を連結することで海上や水上に発電、エアーレーション、ヨットの推進力に使用するエネルギー、動力を得るための風車を設置できる大きな浮台を形成することができる。
【0022】
浮台1の連結に溶接やボルト等を使用しないで針金等の線形材料17を使用しているので組立分解が容易である。よって、浮台1の設置場所の移動が容易にできる。又、固定板3の上端を連結具(菅材)14の内面18に突き当てて固定するので固定板3の上端が連結具(菅材)14の内面18に密着する。よって、連結具(菅材)14は固定板3の上端と平行に固定することができる。
【0023】
ペットボトル4の口部を取付板11と平板5で支持しているので、ペットボトル4に加わる浮力を平板5で確実に受けることができる。又、浮台1に捩り等の力が加わっても浮力を有するペットボトル4は1つ1つ独立しているのでペットボトル4には捩り力は直接加わらない。よって、ペットボトル4が壊れる可能性が少ないので浮台1が浸水することはない。
【0024】
更に、ペットボトル4の水没部分である側部と下部は半割の竹13で覆われているので、水中の異物や水上の浮遊物からペットボトル4を保護することでき、ペットボトル4に異物や浮遊物が当たって穴が開いたりすることがない。又、全体に使用されている各部品の形状が簡単であるので、加工、制作費が安くなると共に、ペットボトル4は廃品であるし、その他の材料に竹、木を用いると材料費が安くなる。
【0025】
次にフロートに薬品が入っていた廃品のビニール袋を用いた浮台の実施形態(ロ)について図6から図9を用いて説明する。図6は浮台21の正面図、図7は浮台21の側面図、図8は浮台21の平面図、図9は浮台21のA−A断面図である。
【0026】
浮台21は並行に配置された複数の菅材22と、その菅材22の間隔を一定に保持するために一定間隔L2で配置された固定具23とで形成されたトラス構造の菅材2と固定具23とで形成された空間に複数のフロート24が挿入されて形成される。
【0027】
菅材22は、図7に示すように横に並べられた3個のフロート24の上部とフロート24の間に並行に並べて設けられる。固定具23は、図9に示すように2枚の固定板25をスペーサ26の両端にボルト27で固定して形成される。固定板25は菅材22が貫通する孔28が設けられ、一定間隔L3で並行に配置される。複数の菅材22を一定間隔L2では配置された固定具23の固定板25の孔28に挿入することで、菅材22と固定具23とでトラス構造が形成されている。フロート24は、図9に示すようにこの固定具23の固定板25の間L2、L3と菅材22とで囲まれた空間に配置される。そして、フロート24の外周の側部と下部は、図6、7に示すように紐で簾状に連結した半割の竹29で覆われ、更にその外周の数ヶ所をステンレスの針金、ロープやワイヤー等の線形材料30で緊縛することで浮台21が形成されている。又、浮台21を連結具(菅材)31で連結する構造は実施形態(イ)と同様である。
【0028】
尚、本実施形態においては、菅材22は竹で、スペーサ26は塩化ビニール等の樹脂で、固定具23の固定板25はコンパネ(木製)で形成される。又、空間に挿入されるフロート24は薬品が入っていた廃品のビニール袋である。更に、複数の菅材22は平行に並べられ、固定具23の2枚の固定板25も平行に並べられている。
【0029】
上記実施形態(ロ)においては、菅材22と固定板25とで形成したトラス構造の空間にフロート24を挿入した浮台21であるので、船のように枠組みを形成する必要がなく、又複数のフロート24を連結するための構造も必要ない。又、菅材22と固定板25とのトラス構造の形成には溶接やボルト等を使用しないで針金等の線形材料30を使用しているので分解組立が容易である。よって、浮台21の設置場所の移動が容易にできる。更にトラス構造であるので強度がある。
【0030】
浮台21に連結部が形成されて他の浮台1と連結具(菅材)31で連結することができるので、複数の浮台21を連結することで海上や水上に発電、エアーレーション、ヨットの推進力に使用する動力を得るための風車を設置できる大きな浮台を形成することができる。
【0031】
浮台21の連結に溶接やボルト等を使用しないで針金等の線形材料を使用しているので組立分解が容易である。よって、浮台21の設置場所の移動が容易にできる。又、固定板25の上端を連結具(菅材)31の内面に突き当てて固定するので固定板25の上端が連結具(菅材)31の内面に密着する。よって、連結具(菅材)31は固定板25の上端と平行に固定することができる。
【0032】
更に、フロート24は薬品が入っていたビニール袋であるので、分解したときに空気を抜くことでフロート24をコンパクトにできる。又、フロート24の空気を抜いた状態で組立てたトラス構造の空間に入れてから、フロート24に空気を入れて膨らますことができるので組立が簡単になる。
【0033】
次に固定板の上部に連結部のないタイプの浮台の実施形態(ハ)について図10、図11を用いて説明する。図10は浮台41の正面図、図11の(a)は浮台41のA−A断面図、(b)は浮台41のB−B断面図である。
【0034】
浮台41は並行に配置された複数の菅材42と、その菅材42の間隔を一定に保持するために一定間隔L4で配置された固定具43とで形成されたトラス構造の空間に複数のフロート44が挿入されて形成される。
【0035】
菅材42は、図11の(a)A−A断面図に示すようにフロート44の周囲を囲むように一定間隔で並行に並べて設けられる。固定具43は、2枚の固定板45が一定間隔L5で並行に配置され、その間隔L5にスペーサ46を入れて両端を固定板45にボルト47で固定されて形成される。そして、固定板45には菅材42が貫通する孔48が設けられる。その孔48に複数の菅材42が挿入され、2枚の固定板45の間L5で複数の菅材22が針金、ロープやワイヤー等の線形材料49で緊縛される。これにより、菅材22と固定具43とでトラス構造が形成される。フロート44は、このトラス構造の固定具43の間L4と菅材42とで囲まれた空間に挿入される。
【0036】
尚、本実施形態においては、菅材42は竹で、スペーサ46は塩化ビニール等の樹脂で、固定具43の固定板45はコンパネ(木製)である。又、空間に挿入されるフロート44は薬品が入っていた廃品のビニール袋である。更に、複数の菅材42は平行に並べられ、固定具43の2枚の固定板45も平行に並べられている。
【0037】
本実施形態の浮台41を菅材42の軸方向に複数接続して上面に半割の竹50を敷詰めることで橋として使用することができる。この橋を陸から海上、水上に突出して設け、ロープやワイヤーにより陸に固定されると桟橋が形成される。
【0038】
上記実施形態(ハ)の浮台41においては、実施形態(ロ)と同様の作用効果を有する。
【0039】
最後にフロートをネットで包み込むタイプの浮台の実施形態(ニ)について図12、13を用いて説明する。図12(a)は6つの浮体62で形成した浮台61、(b)は4つの浮体62で形成した浮台61の平面図、図13は浮体62の斜視図である。
【0040】
浮台61は、図12(a)に示すように浮体62を六角形の角に、又は図12(b)に示すように四角形の角に配置し、菅材63によって連結することで構成されている。本実施形態の菅材63としては1本の竹を用いていているが、特願2002−239221の記載された竹トラスを用いても良い。
【0041】
浮体62は、図13に示すように水平な板材64の下面に複数のフロート65をネット66でまとめられて取付けられた構成である。
【0042】
尚、本実施形態においては、フロート65は薬品等が入っていた廃品となるビニール袋である。又、ネット66はナイロン製の紐、水平な板材64はコンパネ(木製)、菅材63は1本の竹である。
【0043】
上記実施形態(ニ)を風車の浮台61として使用した場合について図14から図15を用いて説明する。図14は浮台61に三脚型風車67を設置した図、図15は浮台61に鳥居型風車68を設置した図である。
【0044】
三脚型風車67の設置について説明する。図14(a)に示すように六角形の角に配置された浮体62の斜線で示した浮体62に、三脚型風車の支柱69が設置されて、図14(b)に示すように三脚型風車67の浮台61として使用される。この場合、三脚型風車の支柱69が荷重位置に当たり、支柱69に浮体62が配置される。
【0045】
鳥居型風車70の設置について説明する。図15(a)に示すように斜線で示した四角形の対角に配置された浮体62に、鳥居型風車の支柱70が設置されて、図15(b)に示すように鳥居型風車68の浮台61として使用される。この場合、鳥居型風車の支柱70が荷重位置に当たり、支柱70に浮体62が配置される。
【0046】
このように浮台61に三脚型風車68や鳥居型風車67を設置され、この風車のエネルギー、動力を、実施形態(イ)(ロ)と同様に発電、エアーレーションやヨット(浮台61)の推進力として利用できる。
【0047】
上記実施形態(ニ)の浮台61においては、何れの風車においても荷重位置である支柱69,70が浮体62に配置されているので、風車の荷重を確実に浮体62で受けることができる。よって、風車が浮台61に安定して設置できる。そして、複数のフロート65をネット66で包み込んで一体としているので、個々にフロート65の取付ける必要が無くなる。よって、フロート65の取付構造が簡単になるので加工費や組立費等の制作費が安くなる。又、組立分解が容易になるので設置場所の移動が可能になる。更に本実施形態においては、菅材63は竹で製作されているので軽量である。よって、設置場所の移動が更に容易になる。そして、本実施形態においては、菅材63は竹、板材64はコンパネ(木製)、フロート65は薬品が入っていた廃品のビニール袋、ネット66はナイロン製であるので材料費が安くなる。
【0048】
尚、上記実施形態(イ)(ロ)(ハ)(ニ)に使用する菅材2、22、42、63や連結具(菅材)14、31等に使用する竹や半割の竹13、29、50は、薬剤を用いず加熱により殺菌されているので、環境を汚染することがない。又、加熱は油やマイクロ波を用いて行い、加熱用油に廃油が使用されると殺菌する費用も安価になる。
【0049】
本発明は、上記実施形態(イ)(ロ)(ハ)(ニ)に限定されず、次のような構成の別実施形態がある。

【Example】
First, an embodiment (a) of a type of float that uses a plastic bottle as a float will be described with reference to FIGS. 1 to 5. FIG. 1 is a front view of the pontoon 1, FIG. 2 is a side view of the pontoon 1, FIG. 3 is a plan view of the pontoon 1, FIG. It is BB sectional drawing.
[0012]
The float 1 is formed by inserting a plurality of plastic bottles 4 into a space of a truss structure formed by a plurality of tube members 2 arranged in parallel and a fixing plate 3 holding the tube members 2 at a constant interval L1. Is done.
[0013]
First, the truss structure will be described. As shown in FIGS. 2 and 4, the fixing plate 3 is provided with a plurality of tenons 19 at both ends of the flat plates 5 and 6, and a plurality of tenon grooves 20 at the center of the fixing plate 3. Fixed at right angles to both ends. The plurality of tube members 2 are inserted into holes 7 or concave grooves 8 provided in the fixing plate 3 and arranged in parallel around the plurality of plastic bottles 4. As shown in FIGS. 2, 4, and 5, the tube member 2 is fixed to the fixing plate 3 by being bound by a linear material 9 such as a wire on the side surface of the fixing plate 3. As shown in FIGS. 2 and 4, a specific method of binding the tubing material 2 with the linear material 9 is to tie the tubing material 2 into a lower portion, a side portion, an upper left portion, and an upper right portion of the plastic bottle 4. In the lower part, two tube members 2 are bound by one linear material 9. On the side, four tube members 2 provided on the left and right sides are bound by one linear material 9. The two upper tube members 2 at the upper left and the upper right are bound together in a triangular shape by a projection 10 provided at the center of the fixed plate 3 and a linear material 9. In this way, a truss structure of the tube member 2 and the fixing plate 3 is formed.
[0014]
Next, the mounting structure of the PET bottle 4 will be described. The mouth of the plastic bottle 4 is inserted into a hole 12 of a strip-shaped mounting plate 11 as shown in FIG. 5, and this mounting plate 11 is attached to the lower part of the flat plate 5 provided between the fixed plates 3 by a wood screw or the like. Mounted. The bottom of the plastic bottle 4 is supported by a flat plate 6 provided between the fixed plates 3 at L1. As a result, the plurality of plastic bottles 4 are arranged as floats in the space of the truss structure of the tube material 2 and the fixing plate 3. Then, as shown in FIGS. 1 and 5, the bottom part and the lower half of the side part of the floating base 1 are covered with a half-split bamboo 13 connected in a cord-like manner with a string so as to cover the group of plastic bottles 4.
[0015]
In this embodiment, as shown in FIGS. 1 to 5, one floating platform 1 is composed of ten approximately 3 m tube members 2, four fixing plates 3, three flat plates 5, flat plates 6, It is formed by 24 mounting plates 11 and 144 PET bottles 4. The tube material 2 is bamboo, the fixing plate 3, the flat plate 5, the flat plate 6, and the mounting plate 11 are control panels (wooden), and the linear material 9 is a stainless steel wire.
[0016]
Next, a structure for connecting the floating base 1 with the connecting tool 14 will be described with reference to FIGS. A tube material is used as the connecting tool 14 of the present embodiment. The upper end of the fixing plate 3 is inserted into a notch 15 provided on the outer periphery of one end of the connecting member (tube material) 14. A linear member 17 such as a wire inserted into the long hole 16 of the fixing plate 3 causes the upper end of the fixing plate 3 to abut against the inner surface 18 of the connecting member (tube material) 14 on the opposite side of the lacking portion 15. The material 14 is tied up. Thus, one end of the connecting member (tube material) 14 is fixed to the upper end of the fixing plate 3 of the pontoon 1. With the same fixing method, the other end of the connecting member (tube material) 14 is fixed to another floating base 1 and the floating base 1 and the floating base 1 are connected. In addition, the method of connecting the floating base 1 in the axial direction of the tube member 2 is as follows. The hole 7 and the concave groove 8 of the fixing plate 3 through which the tube member 2 penetrates are formed into oval long holes and connected to the respective long holes. By inserting each tube member 2 of the floating table 1 and tightening it, the floating table 1 and the floating table 1 are connected in the axial direction of the tube member 2.
[0017]
In the above embodiment (a), since one floating platform 1 has 144 2 liter plastic bottles 4, when about 60% of the plastic bottles 4 are immersed in water, one floating platform 1 weighs about 170 kg. Has buoyancy. When a total of six floats 1 are connected in the lateral direction by the connecting member 14 and two in the axial direction of the tube 2, a total of six floats can be obtained, so that a buoyancy of about 1 ton (170 kg × 6) can be obtained. A large floating platform connected to the floating platform 1 can accommodate about 1 ton of installed objects. Therefore, a large floating platform on which a windmill can be installed can be formed by connecting a plurality of floating platforms 1. Therefore, energy and power can be obtained by rotating the windmill using the wind blowing on the sea or water. Electric power can be obtained by rotating the dynamo (generator) using this energy and power. In addition, it can be used as aeration by moving the bellows to send air into the water to form bubbles. Further, a screw such as a fault / Schneider propeller is protrudingly provided on the underwater side of the pontoon 1, and the screw can be rotated to be used as the propulsion force of the pontoon 1. Thereby, the floating base 1 can be used even if it is sailed. At this time, the side and lower part of the group of PET bottles 4 are covered with half the bamboo 13, so that the outer shape is smooth and the resistance of water is small, so that the yacht can run smoothly. It can also be used simply as a boat without a windmill, or used as a floating island by installing a house.
[0018]
Since the wind power on the sea or on the water is larger than the wind power on the ground, the wind turbine provided on the sea or on the water can obtain larger electric power than the wind turbine provided on the ground. In addition, there are fewer restrictions on various conditions, such as land acquisition, on the sea and on the water than on land.
[0019]
The aeration and the propulsion force of the yacht (floor 1) utilize the power obtained by the windmill on the spot, so that the power can be used efficiently. In addition, the bellows for aeration and the propeller of the yacht (floor 1) can be operated without applying energy or power from the outside of the float 1.
[0020]
In the above embodiment (a), since the float 1 is a float 1 in which a plastic bottle 4 serving as a float is inserted into the space of the truss structure formed by the tube member 2 and the fixing plate 3, it is necessary to form a frame like a ship. There is no need for a structure for connecting a plurality of floats. Further, since the truss structure of the tube member 2 and the fixing plate 3 is formed of a linear material 9 such as a wire without using welding or bolts, the disassembly and assembly is easy. Therefore, it is possible to easily move the installation location of the pontoon 1. Furthermore, it has strength because it has a truss structure.
[0021]
Since a connecting portion is formed on the pontoon 1 and can be connected to another pontoon 1 by the connecting member 14, the plurality of pontoons 1 are connected to generate power, aeration, and propulsion force of a yacht on the sea or on the water. A large floating platform on which a windmill for obtaining energy and power to be used can be installed can be formed.
[0022]
Since the linear material 17 such as a wire is used for connecting the float 1 without using welding or bolts, assembly and disassembly is easy. Therefore, it is possible to easily move the installation location of the pontoon 1. Further, since the upper end of the fixing plate 3 is fixed by abutting against the inner surface 18 of the connecting member (tube material) 14, the upper end of the fixing plate 3 is in close contact with the inner surface 18 of the connecting member (tube material) 14. Therefore, the connecting member (tube material) 14 can be fixed in parallel with the upper end of the fixing plate 3.
[0023]
Since the mouth of the plastic bottle 4 is supported by the mounting plate 11 and the flat plate 5, the buoyancy applied to the plastic bottle 4 can be reliably received by the flat plate 5. Even if a force such as torsion is applied to the pontoon 1, the torsion force is not directly applied to the PET bottle 4 because the buoyant plastic bottles 4 are independent one by one. Therefore, there is little possibility that the PET bottle 4 will be broken, and the pontoon 1 will not be flooded.
[0024]
Furthermore, since the side and lower part of the PET bottle 4 that are submerged are covered with half the bamboo 13, the PET bottle 4 can be protected from foreign substances in the water and floating substances on the water. No holes are created by hits or suspended matter. Further, since the shape of each component used as a whole is simple, the processing and production costs are reduced, and the plastic bottle 4 is discarded. If bamboo or wood is used for other materials, the material cost is reduced. Become.

As shown in FIG. 9, the float 24 is disposed in a space surrounded by L2 and L3 and the tube member 22 between the fixing plates 25 of the fixing member 23. As shown in FIGS. 6 and 7, the side and lower part of the outer periphery of the float 24 are covered with a half bamboo 29 connected in a cord-like manner with a string, and furthermore, several places on the outer periphery are made of stainless steel wire, rope or the like. The floating platform 21 is formed by binding with a linear material 30 such as a wire. The structure for connecting the pontoon 21 with the connecting member (tube material) 31 is the same as that of the embodiment (a).
[0028]

There is no need for a structure for connecting a plurality of floats 24. Further, since the linear material 30 such as a wire is used for forming the truss structure of the tube member 22 and the fixing plate 25 without using welding or bolts, it is easy to disassemble and assemble. Therefore, it is possible to easily move the installation place of the pontoon 21. Furthermore, it has strength because it has a truss structure.
[0030]
Since a connecting portion is formed on the pontoon 21 and can be connected to another pontoon 1 by a connecting member (tube material) 31, by connecting a plurality of pontoons 21, power generation on the sea or water, aeration, It is possible to form a large floating platform on which a windmill for obtaining power used for propulsion of the yacht can be installed.
[0031]
Since a linear material such as a wire is used for connecting the float 21 without using welding or bolts, assembly and disassembly is easy. Therefore, it is possible to easily move the installation place of the pontoon 21. Further, since the upper end of the fixing plate 25 is fixed by abutting against the inner surface of the connecting member (tube material) 31, the upper end of the fixing plate 25 is in close contact with the inner surface of the connecting member (tube material) 31. Therefore, the connecting member (tube material) 31 can be fixed in parallel with the upper end of the fixing plate 25.
[0032]
Further, since the float 24 is a plastic bag containing a chemical, the float 24 can be made compact by removing air when disassembled. In addition, after the float 24 is evacuated and put into the assembled space of the truss structure, the float 24 can be swelled with air and the assembly is simplified.

【The invention's effect】
According to the first aspect of the present invention, the floating platform can be formed with a simple structure in which the float is simply inserted into the space of the truss structure, so that there is no need to form a frame like a ship, and a plurality of floats are connected. There is no need for a structure to do this. Further, since a linear material such as a wire is used for fixing the tube material to the fixing plate, the truss structure of the tube material and the fixing plate can be easily assembled and disassembled. Therefore, the installation location can be easily moved.
[0051]
According to the second aspect of the present invention, since the floating platform can be connected to another floating platform by a connecting tool, a large floating platform can be formed by connecting a plurality of floating platforms. This large pontoon can be used as a pontoon for wind turbines to obtain power for power generation, aeration and yacht propulsion on the sea or water. In addition, houses can be installed on bridges, piers, ferry boats and floating platforms, and can be used as floating islands.
[0052]
According to the third aspect of the present invention, it is easy to assemble and disassemble the connection between the floats, so that the installation place can be easily moved. Further, since the upper end of the fixing plate is in close contact with the inner surface of the tube, the tube (connecting tool) can be fixed in parallel with the upper end of the fixing plate.
[0053]
According to the fourth aspect of the present invention, the flat plate can surely receive the buoyancy applied to the PET bottle serving as the float. In addition, since the waste plastic bottle is used for the float, the price is reduced and the product is recycled. Furthermore, even if a force such as a twist is applied to the pontoon, the plastic bottles having buoyancy are independent one by one, so that a force such as a twist is not directly applied to the PET bottle. Therefore, there is little possibility that the PET bottle will be broken, and the pontoon will not be flooded.
According to the fifth aspect of the present invention, since the mounting structure of the float installed on the floating body is simplified, production costs such as processing costs and assembly costs are reduced. Further, since the floating body is arranged corresponding to the load position of the object installed on the floating platform, the load of the installed object can be reliably received by the floating body. Therefore, the installation object can be stably attached to the floating platform.
