JP-A-11-255182 JP 55-44081 A JP 58-211987

上述する従来のブイは、構造が複雑で、高価であり、高価であるために大型船舶や多数の船舶が行き来する航路、或いは大型船舶や多数の船舶が立ち入る可能性のある立ち入り禁止区域にしか設置されておらず、設置されている場合でも設置間隔が長くなっているのが実情で、ブイのない箇所では、船舶によっては、夜間に航路を外れて航行したり、障害物に接触し、或いはまた海苔や魚の養殖場、牡蠣筏や定置網の周囲などに入り込んで被害を与える等の問題を生じていた。しかも上記特許文献1に開示された浮標は水面から出る部分が高くなく、遠くから視認し難い難点がある。   The conventional buoys described above are complex and expensive, and are expensive so that they can only be used in routes where large vessels and many vessels come and go, or in restricted areas where large vessels and many vessels may enter. It is not installed, and even if it is installed, the fact is that the installation interval is long, and in places where there are no buoys, depending on the ship, you may sail off the route at night or touch obstacles, Alternatively, problems such as entering seaweed and fish farms, oysters and the surroundings of stationary nets have been caused. In addition, the buoy disclosed in the above-mentioned Patent Document 1 does not have a high portion coming out from the water surface, and has a drawback that it is difficult to visually recognize from a distance.

この点、上記特許文献2及び3に開示される浮標は、水面からの突出部分は比較的高くなるが、浮標に浮力を与えて水面に浮上させるためにポール状の標柱体に大きな浮体を取付け、かつ標柱体を直立させるために標柱体下端に重りを取付けたり、海底に沈める重りを係留索で連結せねばならず、構造が複雑で、全体の重量も嵩みがちである。その上、特許文献3に開示される浮標は、海面に投下する前に重りを係留索で繋がねばならないが、係留索は短過ぎると、浮標が海面下に沈みかねないし、逆に長すぎると、係留索が緩んで浮標が直立できなくなる。また何よりも水深の深い海域では、係留索が長くなり適さない。   In this respect, the buoys disclosed in Patent Documents 2 and 3 above have a relatively high protruding portion from the water surface, but a large floating body is attached to the pole-shaped pillar body to give buoyancy to the buoy to float on the water surface. In order to make the pillar body upright, a weight must be attached to the lower end of the pillar body, or a weight that sinks to the sea floor must be connected by a mooring line, and the structure is complicated and the overall weight tends to increase. In addition, the buoy disclosed in Patent Document 3 must be connected with a mooring cable before being dropped on the sea surface. The mooring line will loosen and the buoy will not be able to stand upright. In addition, mooring lines are unsuitable in deep waters above all.

本発明の目的は、構造を簡単にして軽量かつ安価にし、単に投下するだけで必要な箇所に多数設置することができるようにすると共に、夜間でも、又遠くからでも容易に視認することができるブイを提供しようとするものである。   The object of the present invention is to make the structure simple, light and inexpensive, and to be able to install a large number of places where necessary simply by dropping, and can be easily seen at night or from a distance. Try to provide a buoy.

本発明に係わるブイは、熱可塑性樹脂からなるパイプの上下端を塞いで密閉構造としたもので、パイプには、その一端に重りを取付け、この重りによりパイプを海面に投下したとき、該パイプが魚釣り用の浮きのように海面に直立するようにしたものである。海面より直立するパイプには、少なくとも海面から直立する部分に光を当てると反射する反射手段或いは自ら発光する発光手段が設けられる。パイプにはまた、中間に球状の係止部が設けられる。そしてパイプとは別体の浮体に内面が球状の貫通孔が形成され、該貫通孔にパイプを通して上記係止部を貫通孔に係止させることによりパイプが浮体に支持される。 The buoy according to the present invention has a sealed structure by closing the upper and lower ends of a pipe made of a thermoplastic resin. A weight is attached to one end of the pipe, and when the pipe is dropped onto the sea surface by this weight, the pipe Is designed to stand upright on the sea, like a fishing float. A pipe that stands upright from the sea surface is provided with a reflecting means that reflects at least a portion that stands upright from the sea surface or a light emitting means that emits light. The pipe is also provided with a spherical locking portion in the middle. A through hole having a spherical inner surface is formed in a floating body that is separate from the pipe, and the pipe is supported by the floating body by engaging the engaging portion with the through hole through the pipe.

本発明のブイによると、密閉構造のパイプと重りと、反射又は発光手段からなり、しかも密閉構造のパイプはそれ自体が浮力を有するため、浮体を別に取付けなくてもよく、構造が簡単となること、光を当てたときに反射する反射手段により、或いは暗闇の中でも発光する発光手段により夜間でも容易に視認できること、パイプが中空であることにより、発光手段の電源である蓄電池や発電装置等を取付ける場合でも取付け易くなること、パイプ一端に重りを設けることによりブイは魚釣り用の浮きと同様、海面に横向きに投下しても重りが下向きとなって直立し、反射手段又は発光手段が海面より突出して視認できるようになること、ブイがその長手方向を垂直に向けて自立安定するには、ブイの重心がブイの長手方向下方に偏心して、浮力の中心よりも下方に位置することが必要であるが、パイプが中空で、かつ重りがパイプ下端に設けられることにより、中実のロッド端に重りを取り付けたものと比べ、ブイの重心位置を下げて浮力の中心を上方に位置させることができるようになり、そのため重りの重量を大きくしなくてもパイプが自立し安定し易くなると共に、海面からの高さを高くしたブイを得ることができ、したがってブイや反射又は発光手段を遠くからでも容易に視認できるようになること、パイプが中空で、かつ熱可塑性樹脂製であることによりブイを軽量化できると共に、海面にブイをそのまま投下するだけで必要か所に設置することができ、作業性がよいこと、海面より直立するブイは、重心が下げられるため、波によって大きく揺れた場合でもブイの姿勢を安定させることができること、パイプが熱可塑性樹脂製であることにより、押出成形により容易かつ安価に製作できると共に、パイプの上下端を塞ぐために例えばキャップを取付けるのが、熱融着や接着により容易にでき、また海中で付着する貝類や藻類を金属製のものに比べ、はるかに除去し易くなること、ブイが安価に製作できることにより、必要な箇所に多数設置できること、運搬時にはパイプを浮体より引抜いて分離させることにより嵩張らず、運搬が容易となること、パイプは浮体に対し、任意の向きに傾動しうるので、海面に浮かんだ状態で波により大きく傾くようなことがあってもパイプは浮体の傾きに追従することなく速やかに直立姿勢に戻るようになり、パイプの傾きを小さくすることができること等の効果を奏する。 According to the buoy of the present invention, the pipe having the sealed structure, the weight, and the reflection or light emitting means, and the pipe having the sealed structure itself has buoyancy, so that it is not necessary to separately attach the floating body, and the structure is simplified. In addition, it can be easily visually recognized at night by a reflecting means that reflects when it is exposed to light, or by a light emitting means that emits light even in the dark, and because the pipe is hollow, a storage battery or a power generation device that is a power source of the light emitting means Even if it is attached, it becomes easy to install, and by providing a weight at one end of the pipe, the buoy will stand upright with the weight facing downward even if dropped horizontally on the sea surface, like the fishing float, and the reflecting means or light emitting means will be off the sea surface In order for the buoy to be visible, and for the buoy to be self-supporting and stable with its longitudinal direction oriented vertically, the center of gravity of the buoy is decentered downward in the longitudinal direction of the buoy and floats. Although the pipe is hollow and the weight is provided at the lower end of the pipe, the center of gravity position of the buoy is lower than that of the weight attached to the solid rod end. The center of the buoyancy can be lowered and the pipe can be made self-supporting and stable without increasing the weight of the weight, and a buoy with an increased height from the sea surface can be obtained. Therefore, the buoy, reflection, or light emitting means can be easily seen from a distance, the pipe is hollow and made of thermoplastic resin, the buoy can be reduced in weight, and the buoy is dropped directly on the sea surface. The buoy can be installed where it is needed, has good workability, and the buoy that stands upright from the sea level lowers the center of gravity. Because it can be stabilized, and the pipe is made of thermoplastic resin, it can be manufactured easily and inexpensively by extrusion molding, and it is easy to attach a cap, for example, to close the upper and lower ends of the pipe by thermal fusion or adhesion can also compare the shellfish and algae adhering in the sea to the one made of metal, it tends to much removed, by the buoy can be inexpensively manufactured, it can be installed a number where necessary, pull out from the floating body to the pipe at the time of transportation It is not bulky and can be easily transported by separating, and the pipe can tilt in any direction with respect to the floating body, so even if the pipe is tilted greatly by waves while floating on the sea surface, the pipe It returns to an upright posture promptly without following the inclination, and there is an effect that the inclination of the pipe can be reduced .

本発明で用いるパイプの材質の熱可塑性樹脂としては、好ましくは化学的にも安定し、耐候性及び耐久性に優れ、しかも可撓性を有して、船舶と接触しても撓んで衝撃を吸収し、船舶を傷つけることのないポリオレフィン、特にポリエチレンが好ましい。   The thermoplastic resin of the pipe material used in the present invention is preferably chemically stable, excellent in weather resistance and durability, and has flexibility so that it can bend and impact even when it comes into contact with a ship. Polyolefins, especially polyethylene, that absorb and do not damage the ship are preferred.

パイプに取付けられる重りは、パイプの一端に外側から取付けてもよいが、好ましくはパイプの一端に挿入される。パイプに挿入される重りの場合、パイプが密閉構造をなすことにより重りが海水等に接して腐食することがなくなり、そのため重りを任意の材質にすることができる。   The weight attached to the pipe may be attached to one end of the pipe from the outside, but is preferably inserted into one end of the pipe. In the case of a weight inserted into a pipe, the weight is prevented from being in contact with seawater or the like due to the sealed structure of the pipe, so that the weight can be made of any material.

パイプに挿入される重りとしては、例えば鉄製の鋳物、鉄屑等の金属製の重り、パイプに流し込んで形成されるコンクリート製の重り等を用いることができ、なかでも比重が大で、安価な鉄製重りが望ましい。   As the weight inserted into the pipe, for example, iron casting, metal weight such as iron scrap, concrete weight formed by pouring into the pipe, etc. can be used, among which the specific gravity is large and inexpensive. An iron weight is desirable.

パイプに挿入される上記重りはまた、海面を浮遊中にパイプ内を上方に向かって移動しない程度にパイプに固定されるのが望ましい。そのためには例えば、重りに鉄球を使用する場合、鉄球をパイプに充填後、コンクリートを流し込むのが望ましい。これにより重りが安価となり、かつパイプ下部に固定することができる。   The weight inserted into the pipe is also preferably fixed to the pipe so as not to move upward in the pipe while floating on the sea surface. For this purpose, for example, when an iron ball is used as a weight, it is desirable to pour concrete after filling the iron ball into a pipe. This makes the weight cheaper and can be fixed to the lower part of the pipe.

本発明で用いる光反射手段としては、例えばパイプに巻付けて接着される反射テープ、パイプに取付けられる反射板等を例示することができ、反射手段としては乱反射するものが好ましい。   Examples of the light reflecting means used in the present invention include a reflective tape wound around a pipe and bonded thereto, a reflecting plate attached to the pipe, and the like.

発光手段としては、例えば蓄電池、太陽電池パネル、波力或いは風力発電装置などの発電装置を電源として発光する発光ランプ又は発光LED等の発光装置、或いはパイプの表面に塗布される蛍光塗料、蓄光顔料入りの塗料、熱可塑性樹脂製のパイプに含有されるか、二層構造をなす熱可塑性樹脂製パイプの表層部に含有される蛍光顔料又は蓄光顔料を例示することができる。   As the light emitting means, for example, a light emitting device such as a light emitting lamp or a light emitting LED that emits light by using a power generation device such as a storage battery, a solar battery panel, a wave power or a wind power generation device, or a fluorescent paint or a phosphorescent pigment applied to the surface of a pipe. Examples thereof include fluorescent pigments or phosphorescent pigments that are contained in a paint, a pipe made of thermoplastic resin, or contained in a surface layer portion of a thermoplastic resin pipe having a two-layer structure.

蛍光顔料、蓄光顔料入りの塗料は、既存のパイプに対しても、その表面に塗装することが可能で、これにより、夜間でも反射または発光して視認することができる。
発光手段として使用される蛍光顔料と蓄光顔料のなかでは、蓄光顔料が好ましい。蓄光顔料は光を当てると、光が当たらなくなったのちも暫時発光し、残光性を備えるからである。
The coating material containing the fluorescent pigment and the phosphorescent pigment can be applied to the surface of an existing pipe, so that it can be visually reflected or emitted at night.
Of the fluorescent pigments and phosphorescent pigments used as the light emitting means, phosphorescent pigments are preferred. This is because the phosphorescent pigment emits light for a while after being exposed to light and has afterglow properties.

こうした蓄光顔料としては、例えば硫化亜鉛タイプの蓄光顔料、アルミン酸ストロンチウム蓄光顔料、珪素アルミン酸ストロンチウム等を挙げることができ、この中では、残光時間が長くて、耐候性と蓄光性に優れ、水中においても中性であり、耐水性に非常に優れた珪素アルミン酸ストロンチウムが好ましい。   Examples of such phosphorescent pigments include zinc sulfide type phosphorescent pigments, strontium aluminate phosphorescent pigments, strontium silicon aluminate, etc., among which, afterglow time is long, and weather resistance and phosphorescent properties are excellent. Strontium silicon aluminate, which is neutral in water and has excellent water resistance, is preferred.

蛍光顔料又は蓄光顔料を含有させた熱可塑性樹脂製のパイプは、押出成形によって容易に得ることができ、また蛍光顔料又は蓄光顔料を表層部のみに含有させたパイプは、比較的高価な蛍光顔料又は蓄光顔料の使用量を少なくし、パイプの製作コストを低減させることができる。   A pipe made of a thermoplastic resin containing a fluorescent pigment or a phosphorescent pigment can be easily obtained by extrusion molding, and a pipe containing a fluorescent pigment or a phosphorescent pigment only in the surface layer is a relatively expensive fluorescent pigment Alternatively, the amount of phosphorescent pigment used can be reduced and the production cost of the pipe can be reduced.

本発明に係るブイは、夜間でも視認することができる船舶の航路標識として、或いはまた障害物や、海苔、魚等の養殖場、牡蠣筏や定置網の周辺等船舶の立ち入り禁止区域を表示する標識として使用することができる。また潮流を調べるための漂流ブイとして用いることもできるが、航路標識として、或いは船舶の立ち入り禁止区域または航行規制区域を表示するための標識として設置する場合は、上記パイプに突設され、海底に沈められた例えば金属又はコンクリート製のアンカー及び若しくはブイ同士を連結するチェーン、ワイヤー、ロープ等の係留索を繋ぐための係留部を備えていることが望ましい。係留部は、係留索を繋ぐことができるものであれば、どのような構造のものであってもよい。敢えて例示すれば、フック状のもの、リング状のものが挙げられる。   The buoy according to the present invention is a sign for indicating a restricted area of a ship, such as a ship's route sign that can be seen at night, or also around an obstacle, aquaculture of seaweed, fish, etc. Can be used as It can also be used as a drifting buoy for investigating tidal currents, but when installed as a navigational sign or as a sign to indicate a restricted area or restricted area of a ship, it is projected on the pipe and It is desirable to provide a mooring section for connecting anchors such as chains, wires, ropes and the like that sunk metal or concrete anchors and / or buoys. The mooring portion may have any structure as long as it can connect the mooring lines. If it dares to illustrate, a hook-shaped thing and a ring-shaped thing are mentioned.

本発明のブイはまた、複数個線状に間隔を置いて並べることにより、航路或いは立ち入り禁止区域が明確に表示され、船舶などから容易に認識できるようになる。その場合、複数個のブイは係留部をロープなどで繋いでおくのが望ましい。
また本発明のブイを潮流を調べる漂流ブイとして用いる場合は、位置を知らせる発信器を搭載するが、反射または発光手段により視認性が高まるため回収し易くなる。
The buoy according to the present invention can also be easily recognized from a ship or the like by clearly displaying a route or a restricted area by arranging a plurality of buoys at intervals. In that case, it is desirable to connect the mooring portions of the plurality of buoys with a rope or the like.
When the buoy of the present invention is used as a drifting buoy for checking tidal currents, a transmitter for informing the position is mounted. However, since the visibility is enhanced by reflection or light emitting means, it is easy to collect.

本発明におけるパイプは、外径を一定にするか、或いは下端に向けて段階的に大きくするのが好ましい。
外径が一定のパイプは、押出成形されたストレートパイプを一定長さに切断するだけでそのまま使用することができ、構造が最も単純で安価なものとなる。また外径を下端に向けて段階的に大きくしたパイプは、内部に重りをたくさんいれられるので重心が下がって海面での姿勢がより安定するようになる。なお、径の異なるパイプ同士は、レジューサパイプで接続してもよい。
The pipe of the present invention preferably has a constant outer diameter or increases in steps toward the lower end.
A pipe having a constant outer diameter can be used as it is by simply cutting an extruded straight pipe into a certain length, and the structure is the simplest and inexpensive. In addition, pipes with an outer diameter that gradually increases toward the lower end can be loaded with a lot of weight, so the center of gravity is lowered and the attitude on the sea surface becomes more stable. Note that pipes having different diameters may be connected by a reducer pipe.

本発明の好ましい態様として、上記係止部に喫水線を位置させる。
係止部は球状で、パイプより径大をなす。そこで係止部に喫水線を位置させるようにすると、水中に浸かる部分の容積が大きくなり、そのため浮力の中心が水面近くなって重心より上方に離れて位置するようになり、したがってブイが傾いても自立する方向に復元し易くなる。またブイを塩分濃度の濃い海域と、河口や湖のように塩分濃度の低い海、或いは塩分濃度のない水域とでは、ブイの喫水位置が変化するが、径大部に喫水線を位置させるようにすると、喫水位置の変化が少なくなり、海面からの突出量もほぼ一定にすることができる。この理由は次の通りである。
As a preferable aspect of the present invention, a water line is positioned at the locking portion .
The locking part is spherical and has a larger diameter than the pipe. Therefore , when the water line is positioned at the locking portion , the volume of the portion immersed in the water increases, so that the center of the buoyancy is close to the water surface and is positioned above the center of gravity, so even if the buoy is tilted It becomes easy to restore in the direction of self-support. In addition, the buoy's draft position changes between the sea area where the salinity is high and the sea where the salinity is low, such as an estuary or a lake, or the water area where there is no salinity, but the draft line is located at the large diameter part. Then, the change of a draft position decreases and the protrusion amount from the sea surface can also be made substantially constant. The reason is as follows.

いま、海面下のブイの容積をvとし、海水の比重をγとすると、ブイの重量=ブイの浮力=v・γとなるが、このブイを例えば河口に設置した場合、水の比重がγ−Δγになったとすると、ブイの浮力は(γ−Δγ)・(v+Δv)となり、水面下の容積がΔvだけ増えることとなる。径大部の外周線で囲まれた断面積をAとすると、喫水線の上昇量ΔhはΔv=A・Δhとなり、A が大きくなる程、喫水線の上昇量Δhが少なくなる。
本発明においても径大部以外のパイプは、径が一定であってもよいし、下端に向かって段階的に大きくなっていてもよい。
Now, if the volume of the buoy under the sea surface is v and the specific gravity of the seawater is γ, the weight of the buoy = buoyancy of the buoy = v · γ. Assuming −Δγ, the buoyancy of the buoy becomes (γ−Δγ) · (v + Δv), and the volume under the water surface increases by Δv. Assuming that the cross-sectional area surrounded by the outer peripheral line of the large diameter portion is A, the amount of increase Δh of the draft line is Δv = A · Δh, and the amount of increase Δh of the draft line decreases as A 1 increases.
Also in the present invention, the pipes other than the large-diameter portion may have a constant diameter or may gradually increase toward the lower end.

なお、浮体はパイプ自体がかなりな浮力を有するので、大きくする必要はない。   Note that the floating body does not need to be large because the pipe itself has a considerable buoyancy.

係止部を有するパイプは、軸方向の断面の輪郭形状が円形をなす環状体にストレートなパイプを差し込んでパイプ中間で環状体を接着或いは融着することにより得ることができ、また突出部を有する型成形したパイプと、押出成形したストレートなパイプを接続することによっても得ることができる。 A pipe having a locking portion can be obtained by inserting a straight pipe into an annular body having a circular cross-sectional profile in the axial direction and bonding or fusing the annular body in the middle of the pipe. It can also be obtained by connecting a molded pipe having an extruded straight pipe.

本発明において、発光手段がパイプに取り付けられた発光ランプ或いは発光LEDであり、上記パイプには、該発光ランプ或いは発光LEDを発光させるための蓄電池、又は太陽電池パネル、波力或いは風力発電装置等の発電装置等が設けられる。
上述する発光手段のなかでは、消費電力が比較的少ない発光LEDが望ましく、その電源もメンテナンスをほとんど要することなく、長期間に亘っての使用が可能な太陽電池パネルが望ましい。この発光手段を用いた場合、遠方からの視認性をより高めることができる。
なお、発光ランプ或いは発光LEDの取付け位置はパイプの海面から突出する部分であればよい。
In the present invention, the light-emitting means is a light-emitting lamp or a light-emitting LED attached to a pipe, and the pipe has a storage battery, a solar battery panel, a wave power or a wind power generator for causing the light-emitting lamp or the light-emitting LED to emit light. The power generation device is provided.
Among the light-emitting means described above, a light-emitting LED with relatively low power consumption is desirable, and a solar cell panel that can be used for a long period of time without requiring little maintenance is also desirable. When this light emitting means is used, the visibility from a distance can be further enhanced.
It should be noted that the light emitting lamp or the light emitting LED may be attached at a position protruding from the sea surface of the pipe.

さらに本発明においては、上述するパイプ又は浮体の側部に係留索を止める係留部が設けられることが好ましい。この係留部はリングの一部が切れているフック状のものでも構わないが、係留索を確実に保持するためにリング状であることが好ましい。
これにより、航行規制等が必要な水域において、適当間隔でブイを並べて隣接するブイ同士をロープなどの係留索で繋ぐことができ、これにより進入禁止になる境界等を明確に表示することができる。このように本発明のブイを複数個水面に並べて、ブイ同士を係留索で繋いだ境界表示手段を構築することができる。
Furthermore, in this invention, it is preferable that the mooring part which stops a mooring line is provided in the side part of the pipe or floating body mentioned above. The mooring portion may be hook-shaped with a part of the ring cut, but is preferably ring-shaped in order to securely hold the mooring line.
This makes it possible to line up buoys at appropriate intervals and connect adjacent buoys with a mooring line such as a rope in a water area where navigation regulation is necessary, thereby clearly displaying the boundary where entry is prohibited. . Thus, a boundary display means can be constructed in which a plurality of buoys according to the present invention are arranged on the water surface and the buoys are connected by a mooring line.
