Description

本発明は水上又は水中航走体に関し、更に詳しくは、送受波器を格納する開口部に繊維強化樹脂からなるソーナードームを容易に取り付けることができ、かつ取り付け後の耐振動性を向上した水上又は水中航走体に関する。   The present invention relates to a surface or underwater vehicle, and more particularly, to a water surface in which a sonar dome made of a fiber reinforced resin can be easily attached to an opening for storing a transducer and vibration resistance after the attachment is improved. Or it relates to an underwater vehicle.

観測船や艦船にソーナーを装備する場合には、船首下部などに形成した開口部内に送受波器を格納すると共に、その送受波器を保護するため、開口部の入口をソーナードームで閉塞するようになっている。   When a sonar is equipped on an observation ship or ship, the transmitter / receiver is stored in an opening formed at the bottom of the bow, etc., and the inlet of the opening is closed with a sonar dome to protect the transmitter / receiver. It has become.

このソーナードームには、従来よりゴム製のソーナードームが用いられているが、近年では、例えば特許文献1のように、水圧に抗する強度をもった繊維強化樹脂製のソーナードームを、先端にビード部を有する取付部材を介して船体と接続する取付構造が採用されている。   Conventionally, a sonar dome made of rubber has been used for this sonar dome. However, recently, a sonar dome made of fiber reinforced resin having strength against water pressure, for example, as in Patent Document 1, is used at the tip. An attachment structure that connects to the hull via an attachment member having a bead portion is employed.

しかしながら、上記の取付構造では、取付部材の他端をソーナードームにボルトにより直接連結しているので、船体からの振動を受けると、その振動がソーナードームに伝搬し、ソーナーの性能を低下させてしまうという問題があった。   However, in the above mounting structure, the other end of the mounting member is directly connected to the sonar dome by a bolt, so that when the vibration from the hull is received, the vibration propagates to the sonar dome and the performance of the sonar is reduced. There was a problem that.

また、三次元的な形状を有するソーナードームを、船体取付部と水気密性を確保した状態で取り付けることが困難であるという問題もあった。   There is also a problem that it is difficult to attach a sonar dome having a three-dimensional shape in a state in which watertightness is secured with the hull attachment part.

本発明の目的は、送受波器を格納する開口部に繊維強化樹脂からなるソーナードームを容易に取り付けることができ、かつ取り付け後の耐振動性を向上した水上又は水中航走体を提供することにある。   An object of the present invention is to provide a waterborne or underwater vehicle that can easily attach a sonar dome made of fiber reinforced resin to an opening for housing a transducer, and has improved vibration resistance after attachment. It is in.

上記の目的を達成する本発明の水上又は水中航走体は、船体の一部に開口部を形成し、該開口部内にソーナーの送受波器を格納すると共に、該開口部を繊維強化樹脂製のソーナードームで閉塞した水上又は水中航走体において、前記ソーナードームと前記開口部の入口とを、2本の環状の補強材を弾性材に埋設してなる接合部材を介して接続したことを特徴とするものである。   The water or underwater vehicle of the present invention that achieves the above object has an opening formed in a part of the hull, a sonar transducer is housed in the opening, and the opening is made of a fiber reinforced resin. In a water or underwater vehicle closed by a sonar dome, the sonar dome and the entrance of the opening are connected via a joining member formed by embedding two annular reinforcing members in an elastic material. It is a feature.

上記の2本の環状の補強材間を保持材で巻き回すことにより、それら補強材同士を接続することが望ましい。   It is desirable to connect the reinforcing members by winding the two annular reinforcing members with a holding member.

上記の弾性材はゴムから、補強材及び保持材は鋼製ワイヤ又は有機繊維のコードから、それぞれ形成することが望ましい。また、開口部は船体の船首に形成するのがよい。   The elastic material is preferably formed from rubber, and the reinforcing material and the holding material are preferably formed from a steel wire or an organic fiber cord. The opening is preferably formed at the bow of the hull.

本発明の水上又は水中航走体によれば、送受波器を格納する開口部の入口と繊維強化樹脂製のソーナードームとを、2本の環状の補強材を弾性材に埋設してなる接合部材を介して接続するようにしたので、接合部材の寸法裕度が大きくなるためソーナードームの取り付けが容易になると共に、取り付け後においてはソーナードームが受けた振動を接合部材が吸収するため耐振動性を向上することができる。   According to the surface or underwater vehicle of the present invention, a joint formed by embedding two annular reinforcing members in an elastic material and an inlet of an opening for housing a transducer and a sonar dome made of fiber reinforced resin. Since the connection is made via a member, the dimensional tolerance of the joining member increases, making it easy to attach the sonar dome, and after the attachment, the joining member absorbs the vibrations received by the sonar dome and is resistant to vibration. Can be improved.

以下に、本発明の実施の形態について、図面を参照して説明する。
図1は、本発明の実施形態からなる水上又は水中航走体におけるソーナードームの組立図を示す。
Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 shows an assembled view of a sonar dome in a water or underwater vehicle according to an embodiment of the present invention.

水上又は水中航走体の船体1の船首2には、ソーナーの送受波器3を格納する開口部4が形成されており、その開口部4を閉塞するように接合部材5を介して繊維強化樹脂製のソーナードーム6が取り付けられる。ソーナードーム6は、造波抵抗を抑えるため、船体1形状の延長にほぼ沿った表面形状を有している。繊維強化樹脂の種類は特に限定するものではないが、強化繊維をガラス繊維、炭素繊維又はアラミド繊維とし、母材に不飽和ポリエステル樹脂、ビニルエステル樹脂又はエポキシ樹脂を用いた繊維強化樹脂などが例示される。   The bow 2 of the hull 1 of the surface or underwater navigation body is formed with an opening 4 for storing the sonar transducer 3, and fiber reinforced through a joining member 5 so as to close the opening 4. A resin sonar dome 6 is attached. The sonar dome 6 has a surface shape substantially along the extension of the shape of the hull 1 in order to suppress wave resistance. The type of the fiber reinforced resin is not particularly limited, and examples thereof include fiber reinforced resins in which the reinforced fiber is glass fiber, carbon fiber or aramid fiber, and the base material is unsaturated polyester resin, vinyl ester resin or epoxy resin. Is done.

接合部材5は、図2に示すように、ビードワイヤ等からなる2本の環状の補強材7を互いに平行になるように配置し、それら補強材7間を接続するようにして補強材7に巻き回した保持材8を、弾性材9に埋設することにより構成される。弾性材9にはゴムを用いると共に、補強材7及び保持材8には鋼製ワイヤ又は有機繊維のコードを用いることが望ましい。有機繊維としては、強度に優れたアラミド繊維や炭素繊維が好ましく用いられる。   As shown in FIG. 2, the joining member 5 is formed by arranging two annular reinforcing members 7 made of bead wires or the like so as to be parallel to each other and winding the reinforcing members 7 so as to connect the reinforcing members 7. It is configured by embedding the rotated holding material 8 in the elastic material 9. It is desirable to use rubber as the elastic material 9 and use steel wires or organic fiber cords as the reinforcing material 7 and the holding material 8. As the organic fiber, an aramid fiber or carbon fiber excellent in strength is preferably used.

このような接合部材5は、図3に示すように、一方の補強材7が埋設された外縁部10を船体1側から延びるビードシート11の凹部12に、他方の補強材7が埋設された内縁部13をソーナードーム6の端部に形成された凹部14に、締付ボルト15とクランプ16を用いて把持することによりそれぞれ締結される。なお、ソーナードーム6の端部外側には振動吸収用の防振ゴム17が設けられており、またソーナードーム6の外表面には補強ゴム18が被覆されている。補強ゴム18と船体1表面とは、整流プレート19により滑らかに接続される。   As shown in FIG. 3, the joining member 5 has the other reinforcing member 7 embedded in the recess 12 of the bead sheet 11 extending from the hull 1 side through the outer edge portion 10 in which one reinforcing member 7 is embedded. The inner edge 13 is fastened to the recess 14 formed at the end of the sonar dome 6 by using a fastening bolt 15 and a clamp 16. A vibration isolating rubber 17 for absorbing vibration is provided outside the end of the sonar dome 6, and a reinforcing rubber 18 is coated on the outer surface of the sonar dome 6. The reinforcing rubber 18 and the surface of the hull 1 are smoothly connected by a rectifying plate 19.

このように、送受波器3を格納する開口部4の入口と繊維強化樹脂製のソーナードーム6とを、2本の環状の補強材7を弾性材9に埋設してなる接合部材5を介して接続するようにしたので、接合部材5の寸法裕度が大きくなるためソーナードーム6の取り付けが容易になると共に、取り付け後においてはソーナードーム6が受けた振動を接合部材5が吸収するため耐振動性を向上することができる。   In this way, the entrance of the opening 4 for housing the transducer 3 and the sonar dome 6 made of fiber reinforced resin are connected via the joining member 5 formed by embedding the two annular reinforcing members 7 in the elastic material 9. Since the dimensional tolerance of the joining member 5 is increased, the sonar dome 6 can be easily attached, and after the attachment, the joining member 5 absorbs vibrations received by the sonar dome 6 and is resistant to damage. The vibration property can be improved.

また、補強材7間に保持材8を巻き回して、弾性材9に埋設することにより、開口部4の入口へのソーナードーム6の取付強度を向上することができる。   Further, by winding the holding material 8 between the reinforcing materials 7 and embedding it in the elastic material 9, the attachment strength of the sonar dome 6 to the entrance of the opening 4 can be improved.

本発明の水上又は水中航走体は、用途は特に限定されるものではないが、ソーナーの性能と静音性とが重視される水中航走体である艦船に好ましく用いられる。   The use of the surface or underwater vehicle of the present invention is not particularly limited, but it is preferably used for a ship that is an underwater vehicle that emphasizes the performance and quietness of the sonar.
