Description

本発明は、海面付近に浮かせて使用する浮魚礁に関する。   The present invention relates to a floating fish reef used by floating near the sea surface.

従来の浮魚礁としては、基本的に、浮体と、当該浮体を海底につなぎ止めるアンカーと、該浮体とアンカーとを繋ぐ係留索とを有しており、該浮体の一部が常に海面上にある表層浮魚礁（特許文献１参照）や、浮体が常に海面下にある中層浮魚礁（特許文献２参照）が知られている。   A conventional floating fish reef basically has a floating body, an anchor that connects the floating body to the seabed, and a mooring line that connects the floating body and the anchor, and a part of the floating body is always on the sea surface. A surface floating fish reef (see Patent Document 1) and a middle floating fish reef (see Patent Document 2) in which a floating body is always under the sea surface are known.

特開平６−１４６７５号公報JP-A-6-14675 実公昭５８−３６２７０号公報Japanese Utility Model Publication No. 58-36270

しかしながら表層浮魚礁では、浮体の一部が常に海面上にあるように設計されており、潮流の速い時や大きな波が生じた時には浮体とアンカーとを繋ぐ係留索に大きな力がかかり、さらに、海面の上下変動等に対応するために係留索が長いことから、耐久性に問題があった。一方、中層浮魚礁では、浮体を常に海面下に置くため係留索が短く、常に緊張係留になるように設計されているため、耐久性に優れているが、浮体が常時海面下にあるために海上からの発見が困難であり、回収作業が繁雑であった。   However, the surface floating fish reef is designed so that a part of the floating body is always on the sea surface, and when the tide is fast or a big wave is generated, a large force is applied to the mooring line connecting the floating body and the anchor, There was a problem in durability because the mooring line was long to cope with the sea surface ups and downs. On the other hand, in middle-floor reef fish reefs, the mooring line is designed to be always moored with short mooring lines to keep the floating body under the sea surface, so it is excellent in durability, but the floating body is always under the sea surface. The discovery from the sea was difficult and the collection work was complicated.

さらに、従来の浮魚礁には回収のための手段が講じられていなかったため、回収には大型のウインチを用いる必要があり、回収費用が膨大であるという問題もあった。   Furthermore, since there is no means for recovery in the conventional floating fish reef, it is necessary to use a large winch for recovery, and there is a problem that the recovery cost is enormous.

本発明の課題は、耐久性が高く、経済的な表層浮魚礁を提供することにあり、さらには、回収作業が容易な浮魚礁を提供することにある。   An object of the present invention is to provide a highly durable and economical surface floating fish reef, and further to provide a floating fish reef that can be easily collected.

本発明の浮魚礁は、浮体と、アンカーと、該浮体とアンカーとを繋ぐ係留索とを有する浮魚礁であって、該浮体の一部が海面上に出た状態と、浮体全体が海面下に位置する状態との間で、該浮体が潮流の速度に応じた位置を取るように該浮体の浮力が調整されており、該浮体に別途係留索を介して標識ブイが取り付けられていることを特徴とする。   The floating fish reef of the present invention is a floating fish reef having a floating body, an anchor, and a mooring line connecting the floating body and the anchor, and a part of the floating body protrudes above the sea surface, and the entire floating body is below the sea surface. The buoyancy of the floating body is adjusted so that the floating body takes a position corresponding to the speed of the tidal current between the state where the floating body is located and a sign buoy is attached to the floating body via a mooring line separately. It is characterized by.

さらに、本発明の浮魚礁においては、浮体とアンカーとを繋ぐ係留索の複数箇所に回収用フックが取り付けられており、それらの回収用フックに順次かけて引き上げることにより容易に回収し得るようにしたことを特徴とする。 Furthermore, as the Te payaos odor of the present invention, the floating body and are collected hook at a plurality of positions of the mooring lines connecting the anchor is attached, it can be easily recovered by pulling sequentially subjected to their recovery hooks It is characterized by that .

本発明によれば、浮体の浮力が調整されていることから、潮流が通常の速度の時は浮体の一部が海面上に出て従来と同様の表層浮魚礁として働き、潮流が速くなった時には浮体が海面下に引き込まれて従来の中層浮魚礁と同様の状態となり、従来の表層浮魚礁に比べて係留索にかかる力が緩和されることから、耐久性が向上する。また、浮体に標識ブイを取り付けているため、浮体全体が海面下に有る時でも当該浮魚礁の位置が容易に認識されるため、浮体に船舶が衝突する危険を回避することができる。さらに、係留索の複数箇所に回収用フックを取り付けてあるので、通常の起重機のクレーンによりそれらの回収用フックに順次かけて容易に当該浮魚礁を引き上げることができ、回収作業を経済的且つ効率よく行うことができる。 According to the present invention, since the buoyancy of the floating body is adjusted, when the tidal current is normal speed, a part of the floating body comes out on the sea surface and works as a conventional surface floating fish reef, and the tidal current becomes faster. Occasionally, the floating body is pulled under the sea surface, and the state becomes the same as that of the conventional middle-floating fish reef, and the force applied to the mooring line is relaxed compared to the conventional surface floating fish reef, so that the durability is improved. In addition, since the sign buoy is attached to the floating body, the position of the floating fish reef can be easily recognized even when the entire floating body is below the sea surface, so that the risk of a ship colliding with the floating body can be avoided. Further, since a plurality of locations of the mooring lines have installed a collecting hook, by conventional hoist crane sequentially subjected to their recovery hook can be easily pulled up those該浮reef, the recovery operations economical and efficient Can be done well.

図１に本発明の浮魚礁の好ましい実施形態の概略構成図を示す。本発明の浮魚礁は基本的に、浮体１０と、アンカー３０と、該浮体１０とアンカー３０とを繋ぐ係留索とを有し、図１の例においては、該係留索が浮体１０の下部に取り付けられた副係留索２１と上部主係留索２２と下部主係留索２３とからなる。また、アンカー３０と下部主係留索２３とはアンカーチェーン３１を介して連結されている。なお、図中２５はクッションフロートを例示したものである。 FIG. 1 shows a schematic configuration diagram of a preferred embodiment of the floating fish reef of the present invention. The floating fish reef of the present invention basically has a floating body 10, an anchor 30, and a mooring line that connects the floating body 10 and the anchor 30. In the example of FIG. The sub mooring line 21, the upper main mooring line 22, and the lower main mooring line 23 are attached. The anchor 30 and the lower main mooring line 23 are connected via an anchor chain 31. In the figure, reference numeral 25 denotes a cushion float.

図２に浮体１０の拡大図を示す。図２に示すように、本例の浮体１０は目の粗い網状の枠体１３の中に複数個のブイ１４を収納してなり、上部に取り付けた甲板１１に標識灯１２や流出警報発信機などの位置監視システム（不図示）が搭載されている。   FIG. 2 shows an enlarged view of the floating body 10. As shown in FIG. 2, the floating body 10 of this example has a plurality of buoys 14 accommodated in a mesh-like frame body 13 having a coarse mesh, and a marker lamp 12 and a spill alarm transmitter on a deck 11 attached to the upper part. A position monitoring system (not shown) is installed.

本発明の浮魚礁においては、例えばブイ１４の個数を調整するなどして、潮流の速度が遅い時には、図２に示すように浮体１０の上部が海面上に出た状態となり、潮流の速度が速い時には、浮体１０全体が海中に引き込まれるように、浮体１０の浮力が調整されている。尚、係留索２１，２２，２３もこれに合わせて従来の表層浮魚礁よりも短く構成することができる。浮体１０が海中に引き込まれる潮流の速度としては、２．５ノット程度が好ましい。これにより、潮流が穏やかな状態では従来の表層浮魚礁と同様に浮体１０の上部が海面上に位置し、潮流の速度が速い時には、従来の中層浮魚礁と同様に浮体１０全体が海中に水没することにより、係留索２１，２２，２３にかかる力を従来の表層浮魚礁よりも大幅に緩和することができる。その結果、耐久性が向上する。   In the floating reef of the present invention, for example, when the number of buoys 14 is adjusted and the tidal current is slow, the upper part of the floating body 10 comes out on the sea surface as shown in FIG. At high speed, the buoyancy of the floating body 10 is adjusted so that the entire floating body 10 is drawn into the sea. In addition, the mooring lines 21, 22, and 23 can be configured to be shorter than the conventional surface floating fish reef. The tidal velocity at which the floating body 10 is drawn into the sea is preferably about 2.5 knots. As a result, when the tide is calm, the upper part of the floating body 10 is located on the sea surface like the conventional surface floating fish reef, and when the tide speed is fast, the entire floating body 10 is submerged in the sea like the conventional middle floating fish reef. By doing so, the force applied to the mooring lines 21, 22, and 23 can be greatly reduced as compared with the conventional surface floating fish reef. As a result, durability is improved.

また、本発明においては、浮体１０に係留索４１を介して標識ブイ４０が取り付けられている。よって、浮体１０が海中に引き込まれて標識灯１２が海上から認識できない場合であっても、当該標識ブイ４０によって当該浮体１０の存在が認識されるため、当該浮体１０への船舶の衝突を回避することができる。標識ブイ４０は、夜間に海上からの視認が容易なように先端に標識灯を付設することが望ましい。   In the present invention, a marker buoy 40 is attached to the floating body 10 via a mooring line 41. Therefore, even when the floating body 10 is drawn into the sea and the marker lamp 12 cannot be recognized from the sea, the presence of the floating body 10 is recognized by the marker buoy 40, thereby avoiding the collision of the ship with the floating body 10. can do. The marker buoy 40 is desirably provided with a marker lamp at the tip so that it can be easily seen from the sea at night.

標識ブイ４０を浮体１０に繋げている係留索４１の長さは、当該浮魚礁を用いる海域を航行する船舶の喫水以上にしておくことが好ましい。これにより、標識ブイ４０が海中に引き込まれた状態では、海面から浮体１０までの深さが当該海域を航行する船舶の喫水以上となるため、浮体１０に船舶が直接衝突する危険を回避することができる。また、標識ブイ４０は浮体１０に比較すると小さく、軽いため、当該標識ブイ４０に船舶が衝突しても被害が小さい。   The length of the mooring line 41 connecting the sign buoy 40 to the floating body 10 is preferably equal to or greater than the draft of the ship navigating the sea area using the floating fish reef. Thereby, in the state in which the sign buoy 40 is drawn into the sea, the depth from the sea surface to the floating body 10 is equal to or more than the draft of the ship navigating the sea area, so that the risk of the ship directly colliding with the floating body 10 is avoided. Can do. In addition, the sign buoy 40 is smaller and lighter than the floating body 10, so damage is small even if a ship collides with the sign buoy 40.

さらに、本発明においては、係留索２１，２２，２３に回収用のフック２４を複数箇所に取り付けておく。これにより、通常の起重機のクレーンで順次、該フック２４をかけて引き上げることで当該浮魚礁を容易に回収することができる。 Further, in the present invention, a hook 24 for recovering the mooring lines 21, 22, 23 mounted at a plurality of locations Contact Ku. Accordingly, the floating fish reef can be easily recovered by sequentially pulling up the hook 24 with a crane of a normal hoist.
