Description

本発明は、空気式防舷材に関し、さらに詳しくは、設置や収容が容易で、良好な緩衝性能を有する空気式防舷材に関するものである。   The present invention relates to a pneumatic fender, and more particularly to a pneumatic fender that is easy to install and accommodate and has good cushioning performance.

潜水艦用の防舷材としては、下端部に錘を接続し、中途まで海水に水没させて内部に空気と水とを密封した縦型の空気式防舷材が知られている（例えば、特許文献１、２参照）。この空気式防舷材は、例えば、外径が２．５ｍ〜３．３ｍ程度、長さが５．５ｍ〜６．５ｍ程度と大型であり、潜水艦用専用岸壁に設置されている。   As a submarine fender, a vertical pneumatic fender is known in which a weight is connected to the lower end of the submarine and submerged in seawater halfway to seal air and water inside (for example, patents) References 1 and 2). This pneumatic fender, for example, has a large outer diameter of about 2.5 m to 3.3 m and a length of about 5.5 m to 6.5 m, and is installed on a submarine dedicated quay.

潜水艦は、このような大型の空気式防舷材が設置されていない一般の岸壁にも一時的に接岸することがあるため、従来、例えば、図４に示すような中空円筒型弾性防舷材１２を搭載していた。この中空円筒型弾性防舷材１２は、ゴムを両端開口の円筒形状に形成したもので、複数を連結索１３で直列に連結して用いられている。   Since a submarine sometimes temporarily touches a general quay where such a large pneumatic fender is not installed, conventionally, for example, a hollow cylindrical elastic fender as shown in FIG. 12 was installed. The hollow cylindrical elastic fender 12 is formed by forming rubber in a cylindrical shape with openings at both ends, and a plurality of the hollow cylindrical elastic fenders 12 are connected in series by a connecting line 13.

しかしながら、この中空円筒型弾性防舷材１２は水没可能なようにある程度、重量が重く設計されており、使用する際の設置や艦体への収容が困難であるという問題があった。また、艦体に搭載するために、例えば、それぞれの中空円筒型弾性防舷材１２の外径は０．３ｍ、長さは１．５ｍ程度の小型にしなければならず、艦体が接岸して圧縮された際には高い反力が生じ、艦体および岸壁に与える負荷が大きくなり、緩衝性能が十分ではないという問題があった。
特開平１１−１１７２６１号公報 特開２０００−８３４９号公報 However, the hollow cylindrical elastic fender 12 is designed to be heavy to some extent so that it can be submerged, and there is a problem that it is difficult to install and accommodate in the hull. For mounting on the hull, for example, each hollow cylindrical elastic fender 12 must have a small outer diameter of 0.3 m and a length of about 1.5 m. When it is compressed, a high reaction force is generated, the load applied to the hull and quay is increased, and there is a problem that the buffering performance is not sufficient.
Japanese Patent Laid-Open No. 11-117261 JP 2000-8349 A

本発明の目的は、設置や収容が容易で、良好な緩衝性能を有する空気式防舷材を提供することにある。   An object of the present invention is to provide a pneumatic fender that is easy to install and accommodate and has good buffering performance.

上記目的を達成するため本発明の空気式防舷材は、互いに連結および分離可能な複数の弾性袋体を備え、前記複数の弾性袋体を内部を連通して直列に連結するとともに、該連通した複数の弾性袋体の内部に気体および液体を密封可能としたことを特徴とするものである。   In order to achieve the above object, a pneumatic fender according to the present invention includes a plurality of elastic bag bodies that can be connected to and separated from each other, and the plurality of elastic bag bodies are connected in series by connecting the inside thereof. The gas and liquid can be sealed inside the plurality of elastic bags.

本発明の空気式防舷材によれば、互いに連結および分離可能な複数の弾性袋体を備え、この複数の弾性袋体を内部を連通して直列に連結する構造によって、必要に応じて空気式防舷材の長さを変えることができるとともに、分離すると小さくなって運搬等がし易く、錘に該当するものがないので軽量化を図ることができ、設置や収容が容易になる。   According to the pneumatic fender according to the present invention, a plurality of elastic bag bodies that can be connected to and separated from each other are provided, and the plurality of elastic bag bodies communicate with each other in series to connect the air as necessary. The length of the type fender can be changed, and when separated, it becomes small and can be easily transported, and since there is nothing corresponding to the weight, the weight can be reduced, and installation and accommodation are facilitated.

また、連通した複数の弾性袋体の内部に気体および液体を密封することによって、内部に密封された液体が、錘となって空気式防舷材を所定の水深に位置させることができる。さらに、内部に密封された気体によって、防舷材が小型であっても圧縮時に良好な緩衝性能を発揮する。   Further, by sealing the gas and liquid inside the plurality of communicating elastic bag bodies, the liquid sealed inside becomes a weight, and the pneumatic fender can be positioned at a predetermined water depth. In addition, the gas sealed inside exhibits good buffering performance during compression even if the fender is small.

以下、本発明の空気式防舷材を図に示した実施形態に基づいて説明する。図２に空気式防舷材１の使用状態の一例を示し、図１では、図２で示した連結した４つの弾性袋体２ａ〜２ｄの中途を省略し、縦断面で構造を示している。   Hereinafter, a pneumatic fender according to the present invention will be described based on the embodiments shown in the drawings. FIG. 2 shows an example of a usage state of the pneumatic fender 1, and FIG. 1 omits the middle of the four elastic bag bodies 2 a to 2 d connected as shown in FIG. 2 and shows a structure in a longitudinal section. .

図示するように、この空気式防舷材１は複数の弾性袋体２ａ〜２ｄが直列に連結されて構成されている。この弾性袋体２ａ〜２ｄは中空状であり、例えば、内層ゴムと外層ゴムとの間に補強層を介挿して構成され、それぞれ上端部および下端部に口金部３を有している。それぞれの弾性袋体２ａ〜２ｄの最外周となる外層ゴムには耐摩耗性・耐候性および海水に対して侵されにくいゴムが採用され、内層ゴムには気密性および水密性に優れたゴムが採用される。尚、この実施形態では、内部に海水Ｗを密封するので、内層ゴムも海水に対して侵されにくい仕様となっている。   As shown in the figure, the pneumatic fender 1 is configured by connecting a plurality of elastic bag bodies 2a to 2d in series. The elastic bag bodies 2a to 2d are hollow, for example, are configured by inserting a reinforcing layer between an inner layer rubber and an outer layer rubber, and have a base 3 at the upper end and the lower end, respectively. The outer layer rubber that is the outermost periphery of each elastic bag 2a to 2d is a rubber that is resistant to abrasion and weather resistance and seawater, and the inner layer rubber is a rubber that is excellent in air tightness and water tightness. Adopted. In this embodiment, since the seawater W is sealed inside, the specification is such that the inner layer rubber is not easily affected by seawater.

弾性袋体２ａ〜２ｄは互いに、それぞれの口金部３の間に介設される連結部４によって、内部が連通して連結され、連結部４と口金部３との連結を外すことで、それぞれの弾性袋体２ａ〜２ｄは容易に分離することができる。   The elastic bag bodies 2a to 2d are connected to each other by connecting portions 4 interposed between the respective cap portions 3, and the inner portions thereof are connected to each other, and the connection between the connecting portion 4 and the cap portion 3 is removed. The elastic bag bodies 2a to 2d can be easily separated.

図１の最上部の弾性袋体２ａの上端部の口金部３および最下部の弾性袋体２ｄの下端部の口金部３には、封止栓５が取付けられ、両封止栓５および連結部４を介した連結によって、連通した複数の弾性袋体２ａ〜２ｄの内部の密封性が維持できる構造となっている。   A sealing plug 5 is attached to the base 3 at the upper end of the uppermost elastic bag 2a and the base 3 at the lower end of the lowermost elastic bag 2d in FIG. By the connection via the part 4, the internal sealing performance of the plurality of elastic bag bodies 2 a to 2 d communicated with each other can be maintained.

また最上部の弾性袋体２ａの上端部および最下部の弾性袋体２ｄの下端部の口金部３の周辺にはそれぞれフック８が備わり、最上部側のフック８には係留索６が、最下部側のフック８には下部吊上げ索７が結びつけられる。   In addition, hooks 8 are provided around the upper end portion of the uppermost elastic bag body 2a and the base portion 3 at the lower end portion of the lowermost elastic bag body 2d, respectively. A lower lifting rope 7 is tied to the lower hook 8.

この空気式防舷材１を使用する際には、まず、上記の連結状態で最上部の弾性袋体２ａの口金部３に封止栓５を取付けず、潜水艦１１から潜水艦１１と岸壁９との間の海に空気式防舷材１を投入する。これによって、自然に最上部の口金部３から内部に海水Ｗが流入し、所定量の海水Ｗが流入した時点で、例えば、係留索６を介して空気式防舷材１をクレーン等で吊上げて、最上部の口金部３に封止栓５を取付けて、内部に海水Ｗと空気Ａを密封する。   When using this pneumatic fender 1, first, the sealing plug 5 is not attached to the base 3 of the uppermost elastic bag 2 a in the above-mentioned connected state, and the submarine 11 to the submarine 11 and the quay 9 Pneumatic fender 1 is thrown into the sea between. Thereby, when the seawater W naturally flows into the inside from the uppermost base part 3 and a predetermined amount of seawater W flows in, for example, the pneumatic fender 1 is lifted by a crane or the like via the mooring line 6. Then, the sealing plug 5 is attached to the uppermost base part 3 to seal the seawater W and the air A inside.

図２に例示するように、係留索６および下部吊上げ索７は岸壁９のアンカー１０に一端を固定され、空気式防舷材１は内部に密封した海水Ｗを錘にして、潜水艦１１と岸壁９との間の所定の水深に連結方向を縦方向にして設置される。尚、空気式防舷材１を所定の水深に位置させるには、内部に密封する海水Ｗの量を調節する。例えば、連通した内部容積の５０％〜６０％程度の量の海水Ｗを密封する。   As illustrated in FIG. 2, the mooring cable 6 and the lower lifting cable 7 are fixed at one end to the anchor 10 of the quay wall 9, and the pneumatic fender 1 uses the seawater W sealed inside as a weight, and the submarine 11 and the quay wall. 9 is installed at a predetermined water depth with a connecting direction of the vertical direction. In order to position the pneumatic fender 1 at a predetermined water depth, the amount of seawater W sealed inside is adjusted. For example, the seawater W in an amount of about 50% to 60% of the communicated internal volume is sealed.

このように設置された空気式防舷材１に潜水艦１１が当接して空気式防舷材１が圧縮されると、連通した弾性袋体２ａ〜２ｄの内部に密封された空気Ａによって、内部容積が比較的小さくても、緩衝性能が向上し、同外径、同長さの従来の中空円筒型弾性防舷材１２に比べて、遥かに優れた緩衝性能を得ることができ、潜水艦１１および岸壁９に与える負荷を軽減して破損等から保護することができる。   When the submarine 11 comes into contact with the pneumatic fender 1 installed in this manner and the pneumatic fender 1 is compressed, the air A sealed inside the communicating elastic bag bodies 2a to 2d Even if the volume is relatively small, the buffering performance is improved, and far superior buffering performance can be obtained compared to the conventional hollow cylindrical elastic fender 12 having the same outer diameter and length, and the submarine 11 In addition, the load applied to the quay 9 can be reduced and protected from breakage and the like.

設置された空気式防舷材１を艦内に収容するには、例えば、係留索６を介してクレーン等で空気式防舷材１を所定位置まで吊上げて、最上部の弾性袋体２ａの口金部３の封止栓５を取外した状態にし、次に下部吊上げ索７を介してクレーン等で空気式防舷材１を最下部側から吊上げて、空気式防舷材１を逆さまにして内部の海水Ｗを排出する。その後、内部が空になった空気式防舷材１を艦上等でそれぞれの弾性袋体２ａ〜２ｄに分離して小さくし、艦内に収容する。   In order to accommodate the installed pneumatic fender 1 in the ship, for example, the pneumatic fender 1 is lifted up to a predetermined position by a crane or the like via a mooring line 6 and the base of the uppermost elastic bag body 2a. The sealing plug 5 of the part 3 is removed, and then the pneumatic fender 1 is lifted from the lowermost side with a crane or the like via the lower lifting rope 7 so that the pneumatic fender 1 is turned upside down. Seawater W is discharged. Thereafter, the pneumatic fender 1 emptied inside is separated into smaller elastic bags 2a to 2d on the ship or the like, and accommodated in the ship.

以上のように、この空気式防舷材１は海水Ｗを錘として使用するので、内部に海水Ｗがない空の状態では重量が軽く、過大な労力を費やすことなく、容易に設置や収容ができる。また、連結する弾性袋体２ａ〜２ｄの数を変えることによって、大きさの異なる潜水艦１１に対応することができるとともに、分離して小さくすることで、運搬や取扱いが容易になり、限られた艦内のスペースを有効に利用して収容することもできる。弾性袋体２ａ〜２ｄの形状、大きさは艦体の大きさ等によって適宜、決定するが、例えば、それぞれの弾性袋体２ａ〜２ｄの外径を０．５ｍ〜０．７ｍ程度、長さを１．０ｍ〜１．５ｍ程度にして、４つ程度連結する。   As described above, since this pneumatic fender 1 uses seawater W as a weight, it is light in an empty state where there is no seawater W inside, and can be easily installed and accommodated without consuming excessive labor. it can. Moreover, by changing the number of elastic bag bodies 2a to 2d to be connected, it is possible to cope with submarines 11 of different sizes, and by separating and reducing the size, transportation and handling become easy and limited. It can also be accommodated using the space inside the ship effectively. The shape and size of the elastic bag bodies 2a to 2d are appropriately determined depending on the size of the hull, etc. For example, the outer diameters of the respective elastic bag bodies 2a to 2d are about 0.5 m to 0.7 m in length. Is about 1.0 to 1.5 m, and about four are connected.

また、それぞれの弾性袋体２ａ〜２ｄが図３（ａ）に例示するように、口金部３周辺の弾性変形によって、連結方向に対して曲げ変形可能に連結されているので、連結状態で外部から曲げ応力を受けた際に、剛体である口金部３および連結部４に過度の曲げ応力が発生することを防止して、口金部３および連結部４の破損を防ぐとともに、この部分の密封性を確保している。   Moreover, since each elastic bag 2a-2d is connected so that bending deformation is possible with respect to a connection direction by the elastic deformation of the circumference | surroundings of the nozzle | cap | die part 3 so that it may illustrate in Fig.3 (a), it is external in a connection state. When bending stress is applied from the base portion 3 and the connecting portion 4 which are rigid bodies, excessive bending stress is prevented, and damage to the base portion 3 and the connecting portion 4 is prevented. The sex is secured.

弾性袋体２ａ〜２ｄどうしを曲げ変形可能に連結するには、実施形態に示したものに限定されず、例えば、図３（ｂ）に示すように、弾性袋体２ａ〜２ｄの口金部３周辺の剛性を高くするとともに、連結部４に可撓性を持たせてもよい。この可撓性を有する連結部４は、空気式防舷材１を吊上げた際の引張り応力に十分耐えることのできる引張り強度を有する必要がある。   In order to connect the elastic bag bodies 2a to 2d so that they can be bent and deformed, they are not limited to those shown in the embodiment. For example, as shown in FIG. 3 (b), the cap portion 3 of the elastic bag bodies 2a to 2d. While increasing the rigidity of the periphery, the connecting portion 4 may be flexible. The flexible connecting portion 4 needs to have a tensile strength that can sufficiently withstand the tensile stress when the pneumatic fender 1 is lifted.

この実施形態では、周囲にある海水Ｗを内部に密封して、コストおよび工数を最小限にして錘として利用しているが、別途、準備した水等の液体を密封してもよく、通常の水を内部に密封する場合は、弾性袋体２ａ〜２ｄの内層ゴムは、海水に対して特別に耐久性のある仕様にする必要はない。また、大気圧の空気Ａを内部に密封しているが、加圧した空気Ａを密封して浮力を確保することもできる。   In this embodiment, the surrounding seawater W is sealed inside and used as a weight with minimum cost and man-hours. However, separately prepared liquid such as water may be sealed. When water is sealed inside, the inner layer rubbers of the elastic bags 2a to 2d do not need to have a specification that is particularly durable against seawater. Moreover, although the atmospheric pressure air A is sealed inside, the pressurized air A can be sealed to ensure buoyancy.

この空気式防舷材１は、潜水艦１１に搭載するだけでなく、陸上に用意しておくこともでき、また、潜水艦１１に用いるだけではなく、種々の船舶に使用することができる。   This pneumatic fender 1 can be used not only for mounting on the submarine 11 but also on land, and not only for the submarine 11 but also for various ships.
