Description

本発明は、津波の来襲時の安全性を考慮した船舶、コンテナおよび木材ブロックなど(以下船舶などという)の漂流抑制システムに関するものである。   The present invention relates to a drifting suppression system for ships, containers, timber blocks, and the like (hereinafter referred to as ships) in consideration of safety during a tsunami attack.

日本には漁船、遊漁船とプレジャーボート合わせて約100万隻ほどあり、そのうちの9割以上が5総トン未満の小型船舶と言われている。
これらの船舶の係留方法では、急激な海面の上昇、低下を伴う大きな津波が襲来した場合、衝撃的な大きな力がもやい綱に加わり、もやい綱が破断して、船溜り、泊地など港内から多数の船舶が一挙に津波とともに漂流を始めること、および船舶が波とともに互いに衝突しながら陸上に遡上し、住宅地や公共施設を襲うこと、また引き潮時には座礁あるいは水路に打ち上げられながら外洋に潮とともに流され多大な損害を与えることは、本年3月11日の東日本大震災津波によって明らかになった。
また、陸上に遡上した津波は港内のヤードのコンテナ、木材なども流し大きな経済的な損害を与えた。
とくに漁船の損壊、流出はその地域の水産業の崩壊につながり、地域経済に大きな打撃を与えることも明らかとなった。
しかし、従来は津波の際に船舶などの流出を阻止する発明はほとんど存在しない。
また、陸上の貯木場の木材、あるいは岸壁に積み上げたコンテナでも同様であって、流れによって打ち上げられるか沖に流されるという現象となって現れた。
There are about 1 million fishing boats, recreational fishing boats and pleasure boats in Japan, more than 90% of which are said to be small vessels with less than 5 gross tons.
In these ship mooring methods, when a large tsunami with a sudden rise or fall of the sea level strikes, a large shocking force is applied to the moist rope, the moist rope breaks, and there are a number of harbors, anchorage etc. Ships begin to drift with the tsunami at once, and the ships collide with each other with the waves and go up to the land, attack residential areas and public facilities, and at the time of the ebb tide, they are launched to the ground or waterway and with the tide to the open ocean It was revealed by the Great East Japan Earthquake tsunami on March 11 this year that it was washed away and caused a great deal of damage.
In addition, the tsunami that went up to land also washed containers, wood, etc. in the yard in the harbor and caused great economic damage.
In particular, it has become clear that the damage and outflow of fishing boats will lead to the collapse of the local fishery industry and will have a major impact on the local economy.
However, there has been almost no invention that prevents the outflow of ships and the like during a tsunami.
The same applies to timbers on land, or containers piled on the quay, and appear as a phenomenon where they are either launched by the flow or washed offshore.

上記のような現象に対して従来は、津波時の港内の急激な海面上昇もしくは低下によって船首もしくは舷側と係船柱が離れようとする力が係留索に衝撃力として働き、もやい綱が切断されるか、あるいは船の係留金具であるビットの破断がおき、あるいは続いてくる急速な潮の流れで漂流を始めるという問題があった。
また陸上のヤードに蔵置してある状態の木材(原木)、コンテナはそのまま浮き上がり流されるのが一般的である。
しかし従来は津波の現象としての研究、船舶などへ働く外力の研究は行われてきたものの、現実に即した漂流抑制システムの開発は行われておらず特許文献を調査しても見つけることができない状態である。
Conventionally, against the above-mentioned phenomenon, the force that tries to separate the mooring column from the bow or the berth side acts as an impact force on the mooring line due to the sudden rise or fall of the sea level in the harbor at the time of the tsunami, and the moist rope is cut Or, there was a problem that the bit that was the mooring bracket of the ship broke, or the drift started with the rapid tide that followed.
In general, timber (raw wood) and containers stored in a land yard are lifted and washed as they are.
However, although research on tsunami phenomena and research on external forces acting on ships have been conducted in the past, no actual drift suppression system has been developed and cannot be found by investigating patent literature. State.

上記のような課題を解決するために本発明の船舶、コンテナおよび木材ブロックの漂流抑制システムは、津波対策のためのシステムであって、船体などには、係留索の先端にフック係止具を取り付け、途中に緩衝材を介在させた漂流防止索を設置し、海底あるいは陸上には漂流防止索の先端のフック係止具が係合可能である捕捉索を設置して構成することを特徴とするものである。
また本発明の船舶、コンテナおよび木材ブロックの漂流抑制システムは、上記のシステムにおいて、漂流防止索の先端のフック係止具は、複数のフックを回転軸で軸止し、フックには外側へ開く弾性を付与し、外周から拘束帯で拘束して構成することを特徴とするものである。
また本発明の船舶、コンテナおよび木材ブロックの漂流抑制システムは、前記のシステムにおいて、捕捉索は、端部を海底、あるいは地中に設置した水平材から構成することを特徴とするものである。
In order to solve the above-described problems, the drift suppression system for a ship, a container and a timber block according to the present invention is a system for countermeasures against tsunami. A drift prevention rope with a buffering material interposed is installed in the middle, and a catching rope that can be engaged with a hook locking tool at the tip of the drift prevention rope is installed on the seabed or on the land. To do.
Further, in the drift suppression system for a ship, a container and a timber block according to the present invention, in the above system, the hook locking device at the tip of the drift prevention rope is fixed to a plurality of hooks by a rotating shaft, and the hook is opened outward. It is characterized by being provided with elasticity and constrained by a restraining band from the outer periphery.
Moreover, the drift suppression system of the ship of this invention, a container, and a timber block is characterized by comprising a trapping rope from the horizontal material which installed the edge part in the seabed or the ground in the said system.

本発明の船舶、コンテナおよび木材ブロックなどの漂流抑制システムは以上のようになるから次のような効果を得ることができる。
<1> 船舶の場合、津波の最初の襲来によって海面が急激に上昇、下降しても、漂流防止索の先端に取り付けたフックが、陸上、海底に設置した捕捉索に係合して船舶などの漂流を阻止することができる。
<2> 陸上のコンテナ、木材ブロックの場合も、それらが遡上した場合には、漂流防止索のフックが同様に捕捉索に掛かり海上への流失、陸上への流入を抑えることができる。津波の第二波、第三波が押し寄せても同じところに留まるか、別の捕捉索に係合するように船舶などの漂流を阻止することができる。
<3> このシステムによって津波による大量の船舶などの漂流を防ぐことができ、港の背後の住宅や公的施設が漂流物によって破壊を受ける危険性を小さくすることができる。
Since the drifting suppression system for a ship, a container, and a wood block of the present invention is as described above, the following effects can be obtained.
<1> In the case of a ship, even if the sea level suddenly rises or falls due to the first attack of the tsunami, the hook attached to the tip of the drift-preventing rope engages with a catching rope installed on land or on the seabed. Can be prevented.
<2> In the case of land-based containers and timber blocks, if they run up, hooks of the drift-preventing rope can be hooked on the catching rope in the same way to suppress the loss to the sea and the inflow to the land. Even if the second and third waves of the tsunami come closer, they can stay in the same place, or they can prevent drifting of ships and the like to engage with another catching line.
<3> With this system, it is possible to prevent a large number of ships from drifting due to the tsunami, and to reduce the risk of the houses and public facilities behind the port being destroyed by drifting objects.

以下図面を参照にしながら本発明の好適な実施の形態を詳細に説明する。   DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

<1>全体の構成
本発明は主に100トン未満の船舶、あるいはコンテナ、木材ブロックを対象とし、漂流防止索と、陸上、海底の捕捉索とによって構成するものである。
この漂流防止索の先端のフックを、陸上、海底の捕捉索にひっかけることによって、船舶などの漂流を抑制する、漂流を抑えるシステムである。
図の実施例では船体1を対象に説明する。
<1> Overall Configuration The present invention is mainly intended for ships of less than 100 tons, containers, and timber blocks, and includes drift prevention cables and land and seabed capture cables.
It is a system that suppresses drifting of ships and the like by hooking the hook at the tip of this drifting prevention rope to the catching cable on the land and seabed, and suppresses drifting.
In the embodiment shown in the drawing, the hull 1 will be described.

<2>漂流防止索
漂流防止索2は、通常の船舶を係留する市販の繊維ロープなど一般的な素材の係留索21と、緩衝材22と、フック3とによって構成する。
係留索21の中間、あるいはその一端に緩衝材22を介在させる。
介在させる緩衝材22は、高い伸縮特性を備えたゴムなどの索、棒または帯状の部材であり、高伸縮特性によって衝撃張力の緩和やエネルギーの吸収を行うものである。
<2> Drifting prevention cable The drifting prevention cable 2 includes a mooring line 21 made of a general material such as a commercially available fiber rope mooring a normal ship, a buffer material 22, and a hook 3.
A buffer material 22 is interposed in the middle of the mooring line 21 or at one end thereof.
The cushioning material 22 to be interposed is a rope, rod, or belt-like member such as rubber having a high stretch property, and reduces the impact tension and absorbs energy by the high stretch property.

<3>フック
漂流防止索2の自由端にはフック3を取り付ける。
フック3は、どの面でも捕捉索に掛かるように鉤31を備えた、従来の錨に似た鋼製または合金製の部材である。
ただし、錨のように常時、周囲に向けて鉤31を突出していては、平常時にも海底の岩や、海底に敷設した捕捉索4と係合してしまう。
そこで一般の雨傘の骨のように、常時は複数本の鉤31を閉じた状態に配置してあり、必要に応じて周囲に向けて鉤31が放射状に拡散する構成を採用する。
そのために例えば図6に示すように、複数本の鉤31の一端を回転軸32に回転自在に軸止めし、かつ中心から周囲に拡大する方向に鉤31の押し出し力を与えておく。
そして常時は、複数本の鉤31をバネに抵抗した状態で収縮し、その周囲を拘束帯33で拘束しておく。
さらにその拘束帯33と係留索21との間を、短い長さの解放索34で接続しておく。
すると船体1などの急激な上昇によって係留索21が引っ張られた場合に、係留索21の引張力がフック3に到着する前に、解放索34からの引張力が拘束帯33を引き出し、あるいは拘束帯33を破壊して、拘束帯33の拘束力を解放する。
その結果、拘束帯33で解放力を拘束されていた多数の鉤31群が、放射方向に解放されて周囲に複数のフック3を張り出した錨状を呈することになる。
<3> Hook A hook 3 is attached to the free end of the drift prevention rope 2.
The hook 3 is a member made of steel or an alloy similar to a conventional kite, provided with a kite 31 so that any surface can be hooked on the catching cable.
However, if the ridge 31 always protrudes toward the periphery like a ridge, it will engage with the rocks on the seabed and the catching cable 4 laid on the seabed even in normal times.
In view of this, a configuration is adopted in which a plurality of ridges 31 are normally arranged in a closed state like a general umbrella, and the ridges 31 are radially diffused toward the periphery as necessary.
For this purpose, for example, as shown in FIG. 6, one end of a plurality of scissors 31 is rotatably fixed to a rotating shaft 32, and an extruding force of the scissors 31 is applied in a direction expanding from the center to the periphery.
And normally, it shrinks in the state which resisted the multiple collars 31 with the spring, and the circumference | surroundings are restrained with the restraint band 33.
Further, the restraint band 33 and the mooring line 21 are connected by a short release cable 34.
Then, when the mooring line 21 is pulled by a sudden rise of the hull 1 or the like, the pulling force from the release line 34 pulls the restraining band 33 or the restraining line 33 before the pulling force of the mooring line 21 arrives at the hook 3. The band 33 is destroyed and the restraining force of the restraining band 33 is released.
As a result, a large number of hooks 31 whose release force is restrained by the restraining band 33 is released in the radial direction and presents a hook-like shape in which a plurality of hooks 3 are projected.

<4>索破断防止装置
津波の来襲時に漂流防止索2には、津波に抗してゴムやスプリングの緩衝材22が働いたままの状態が続く場合がある。
すると緩衝材22の内部に大きなエネルギーが解放されずに蓄積し、破断するおそれがある。
そのため、係留索21を緩めエネルギーを解放してやる必要があり、21索に数メートルあるは数十メートルの索21を繰り出すことができる索破断防止装置5を取り付けることも必要になる。
そのために例えば係留索21の途中に巻尺の巻き取り具のような索破断防止装置5を介在させることもできる。
この索判断防止装置5は、係留索21を巻き取り、折り返して束ね中空の容器に収納した装置である。
内部に収納した係留索21には、バネなどの弾力または容器の出口と係留索21の摩擦力によって引き出しに抵抗を与えておく。
係留索21に一定の外力が作用した場合に、係留索21に抵抗を与えながら徐々に容器から係留索21を引き出すことができる。
したがって津波で船体1が上昇した場合に、船体1に抵抗を与えながら、切断することなく係留索21を引き出して、漂流を阻止することができる。
<4> Cable break prevention device
When the tsunami strikes, the drift prevention rope 2 may remain in a state where the rubber or spring cushioning material 22 remains working against the tsunami.
Then, a large amount of energy is accumulated in the buffer material 22 without being released, and there is a possibility of breaking.
Therefore, it is necessary to loosen the mooring cable 21 and release the energy, and it is also necessary to attach a cable breakage prevention device 5 that can feed out the cable 21 of several meters or several tens of meters to the 21 cables.
For this purpose, for example, a rope breakage prevention device 5 such as a tape measure winder can be interposed in the middle of the mooring line 21.
The cable judgment preventing device 5 is a device that winds up the mooring cable 21, folds it back, and bundles it into a hollow container.
The mooring line 21 housed therein is given resistance to the drawer by the elasticity of a spring or the like or the frictional force between the outlet of the container and the mooring line 21.
When a constant external force is applied to the mooring line 21, the mooring line 21 can be gradually pulled out of the container while applying resistance to the mooring line 21.
Therefore, when the hull 1 is lifted by a tsunami, the mooring line 21 can be pulled out without being cut, and drifting can be prevented while giving resistance to the hull 1.

<5>捕捉索
海底、および陸上に捕捉索4を設置する。
この捕捉索4は、地中、海底に基礎を埋設した水平材によって構成する。
水平材は、鋼棒、鋼線などで構成する。
すなわち「索」と称しても線材に限るものではなく、明細書、請求項ともに鋼棒なども含んだ意味で使用する。
この水平材に、前記したが係合することによってフック3にひっかかるようにすることで船体1の漂流を阻止する。
捕捉索4は、例えば複数本の、平行して設置した支柱の上端を、共通の水平材で連結した構成を採用することができる。
したがって陸上の捕捉索4は、ガードレールや転落防止柵、岸壁コーナー材、クルマ止めなどとして他の機能を付加することもできる。
コンテナターミナルや貯木場では不沈式、起伏式の索のシステムを採用することができる。
これは通常時には荷役活動の妨げにならないように地面の下に水平材の索を設置しておき、津波時には索を支える杭が上昇し、あるいは起き上がることで水平材としての索が地表から数十センチ上昇するように構成する。
あるいは、捕捉索4に浮きを複数個固着して、津波の波が到来したとき、浮きの浮力によって捕捉索4が地上に浮き出るように構成しても良い。
<5> Capture cable The capture cable 4 is installed on the seabed and on land.
This catching rope 4 is constituted by a horizontal material in which a foundation is buried in the ground and the seabed.
The horizontal member is composed of a steel bar, a steel wire or the like.
In other words, the term “cord” is not limited to a wire, and the description and claims are used to include steel bars and the like.
By engaging the horizontal member with the hook 3 as described above, the hull 1 is prevented from drifting.
For example, a configuration in which the upper ends of a plurality of support columns installed in parallel are connected by a common horizontal member can be adopted as the capture cable 4.
Therefore, the land catching cable 4 can also be added with other functions as a guard rail, a fall prevention fence, a quay corner material, a car stopper, and the like.
Unsinkable and undulating rope systems can be used at container terminals and storages.
This is because horizontal ropes are usually placed under the ground so as not to hinder cargo handling activities, and in the case of a tsunami, the piles that support the ropes rise or rise up, and the ropes as horizontal bars are several dozen from the ground surface. Configure to rise centimeters.
Alternatively, a plurality of floats may be fixed to the catching cable 4 so that when a tsunami wave arrives, the catching cable 4 may be raised on the ground by the floating buoyancy.

<6>船舶の挙動の説明
次に平常時と津波来襲時の船舶の挙動と、本発明のシステムの作動について説明する。
<6> Description of Ship Behavior Next, the behavior of the ship during normal times and tsunami attacks and the operation of the system of the present invention will be described.

<7>平常時
平常時には、船体11は通常のもやい綱61で岸壁の係船柱6に係留しているが、同時に船尾から漂流防止索2を海底に垂れ流した状態で停泊している。
その漂流防止索2の先端のフック3は、傘の骨を畳んだように、複数のフック3群を拘束帯33で収納した状態にある。
そのためにフック3の鉤31が海底の岩や、海底に敷設した捕捉索4にひっかかることがない。
船舶が漁などで港の外部に出るときには、漂流防止索2を、先端のフック3とともに船体1の内部に取り込む。
<7> Normal time In normal times, the hull 11 is moored to the mooring column 6 on the quay by a normal mottle 61, and at the same time, the drifting prevention cord 2 is anchored in a state where it spills from the stern to the seabed.
The hook 3 at the tip of the drifting prevention cable 2 is in a state in which a plurality of hooks 3 are housed in a restraining band 33 so that the bone of an umbrella is folded.
Therefore, the hook 31 of the hook 3 does not catch the rock on the seabed or the catching cable 4 laid on the seabed.
When the ship goes out of the port due to fishing or the like, the drift prevention rope 2 is taken into the hull 1 together with the hook 3 at the tip.

<8>海底での係止
津波の影響で海面が急激に上昇すると、船体11が波によって急激に持ち上げられ、係船柱6と船体11を繋いでいた長さ数十センチから1m程度の船首側のもやい綱61は切断される。
津波によって海面が更に上昇して漂流防止索2に引張力が作用すると、先端の解放索34がフック3の拘束帯33を解体し、複数の鉤31はバネの弾力によって放射方向に広がる。
その後さらに漂流防止索2が引かれると、フック3は海底面を引きずられる。そのためにフック3の鉤31が、海底に設置してある捕捉索4に係合し、船体1の漂流を一時的に阻止する。
それ以上に海面が上昇すると、ゴムベルトなどで構成した緩衝材22が伸びて係合状態を維持する。
海面の上昇がこの段階で停止すれば、緩衝材22の伸びによってフック3と捕捉索4との係合を維持し続け、船体1の漂流の阻止の機能を果たすことができる。
<8> Locking at the bottom of the sea When the sea level suddenly rises due to the tsunami, the hull 11 is suddenly lifted by the waves, and the bow side of the tens of centimeters to 1 m that connects the mooring column 6 and the hull 11 The noisy rope 61 is cut.
When the sea level further rises due to the tsunami and a tensile force acts on the drifting prevention cable 2, the release cable 34 at the tip disassembles the restraining band 33 of the hook 3, and the plurality of ridges 31 spread in the radial direction by the elasticity of the spring.
Thereafter, when the drift prevention rope 2 is further pulled, the hook 3 is dragged on the sea bottom. For this purpose, the anchor 31 of the hook 3 engages with the catching cable 4 installed on the seabed, and temporarily prevents the hull 1 from drifting.
When the sea level rises beyond that, the cushioning material 22 formed of a rubber belt or the like extends to maintain the engaged state.
If the rise of the sea level stops at this stage, the engagement between the hook 3 and the catching rope 4 can be maintained by the extension of the buffer material 22, and the function of preventing drifting of the hull 1 can be achieved.

<9>陸上での係止
津波の規模によっては、海面がさらに上昇する。
その場合には海底の捕捉索4が破損し、船体1は漂流防止索2を引きずったままさらに上昇を続ける。
すると漂流防止索2の末端のフック3の鉤31は、陸上に設置したいずれかの捕捉索4に係合することになる。
フック3の鉤31にひっかかった捕捉索4は、岸壁上にガードレール状に設置した捕捉索4の場合もあり(図4)、さらに海面が上昇すれば、防潮堤の頂部に設置した捕捉索4の場合もある。(図5)
図示していないが、いずれの段階でも、緩衝材22とともに、前記した索破断防止装置5が十分働きフック3と捕捉索4がつながっている状態を長く維持することができる。
<9> Locking on land Depending on the scale of the tsunami, the sea level will rise further.
In that case, the capture cable 4 on the seabed is damaged, and the hull 1 continues to rise while dragging the drifting cable 2.
Then, the hook 31 of the hook 3 at the end of the drifting prevention cable 2 is engaged with any of the catching cables 4 installed on the land.
The catching cable 4 caught on the anchor 31 of the hook 3 may be the catching cable 4 installed in the shape of a guard rail on the quay (FIG. 4). If the sea level rises further, the catching cable 4 installed at the top of the tide bank In some cases. (Fig. 5)
Although not shown, at any stage, the state where the hook breakage prevention device 5 described above works sufficiently together with the buffer material 22 and the hook 3 and the catching rope 4 are connected can be maintained for a long time.

<10>引き波時の係合
津波の陸上への遡上が限界に達すると、引き波が生じる。
この引き波によって船体1が沖へ流される可能性があるが、船体1が引きずるフック3は、いずれかの地上の捕捉索4に係合しているから、沖への流出を阻止することができる。
地上の捕捉索4の破損などで、地上への係止が困難となった場合にも、フック3は海底を引きずるから、海底に設けた捕捉索4に係合する可能性が高く、そこで漂流を阻止することもできる。
<10> Engagement at the time of pulling When the tsunami reaches the limit, a pulling wave is generated.
This pulling wave may cause the hull 1 to flow offshore, but the hook 3 dragged by the hull 1 is engaged with any of the ground catching ropes 4, so that it is possible to prevent outflow to the offshore. it can.
Even when it is difficult to lock the ground due to damage to the ground capture line 4, the hook 3 drags the seabed, so there is a high possibility that it will engage with the capture line 4 provided on the seabed. Can also be prevented.

<11>船舶以外
以上は、船体1に漂流防止索2を取り付けた場合の説明であるが、貯木場などに積み上げた木材ブロック、コンテナにおいても同様の効果を期待することができる。
その場合に木材ブロックの外周をワイヤーで拘束し、そのワイヤーに本願発明の漂流防止索2を取り付ける。
あるいはコンテナの底部に開設したフォークリフトのアームを挿入するツイストコーンが着脱する穴に本願発明の漂流防止索2を取り付ける。
するといずれの場合でも津波によって漂流し始めた木材ブロック、コンテナーに一端を固定した漂流防止索2の他端のフック3係止具が、海底あるいは陸上の捕捉索4に係合してそれ以降の漂流を阻止することができる。
<11> Other than Ships The above is a description of the case where the drift prevention rope 2 is attached to the hull 1, but the same effect can be expected in a wood block and a container stacked in a storage yard or the like.
In that case, the outer periphery of the wood block is constrained by a wire, and the drift prevention rope 2 of the present invention is attached to the wire.
Or the drift prevention rope 2 of this invention is attached to the hole which the twist cone which inserts the arm of the forklift established at the bottom part of the container attaches / detaches.
Then, in any case, the wood block that started drifting due to the tsunami, the hook 3 locking device at the other end of the drifting prevention cable 2 fixed at one end to the container, engaged with the seabed or the land capture cable 4 and the subsequent Drifting can be prevented.
