Description

本発明は、船舶用ソナー装置に関する。 The present invention relates to a ship marine sonar equipment.

例えば、小型高速船には喫水下の船首部にソナー装置が設けられ、安全に運航できるようにクジラや流木などのような前方の障害物を探索することが行われ、あるいは、漁船や海洋調査船では船底にソナー装置が設けられ、魚群探知や海底における各種計測が行われている。 For example, small high-speed boats are equipped with a sonar device at the bow of the draft to search for obstacles ahead such as whales and driftwood so that they can be operated safely, or for fishing boats and oceanographic surveys. The ship is equipped with a sonar device at the bottom of the ship, which is used to detect fish schools and to measure various types of sea bottom.

ソナー装置は、船体側で支持された送受波器と、この送受波器を覆うソナードームとを含んで構成され、ソナードームにより送受波器の保護が図られている。
そして、ソナードームに、音響の透過を可能とした音響透過領域と、音響を遮音する遮音領域とが設けられ、送受波器が探索あるいは計測すべき特定の方向においてのみ音響の送受を行なえ、また、砕波雑音などのような特定方向以外からの雑音の送受波器への到達を阻止するようにしている。 The sonar device includes a transducer supported on the hull side and a sonar dome that covers the transducer, and the sonar dome protects the transducer.
The sonar dome is provided with a sound transmission region that allows sound transmission and a sound insulation region that blocks sound, so that sound can be transmitted and received only in a specific direction to be searched or measured by the transducer. In addition, noise from other than a specific direction such as breaking noise is prevented from reaching the transducer.

音響透過領域２２を構成するソナードーム１６の箇所は、コア材３４が、音響の透過を可能とした粘弾性体３４Ａで構成されている。このような粘弾性体３４Ａとして、ゴムやポリウレタンなどの従来公知の様々な材料が使用可能である。 The location of the sonar dome 16 constituting the sound transmission region 22 is constituted by a viscoelastic body 34 </ b> A in which the core material 34 can transmit sound. As the viscoelastic body 34A, various conventionally known materials such as rubber and polyurethane can be used.

また、遮音領域２４を構成するソナードーム１６の箇所は、コア材３４が音響を遮音する(振動雑音の低減を含む)遮音材３４Ｂで構成されている。このような遮音材３４Ｂとして、気泡(ガラスマイクロバルーン)を混在させたゴムやポリウレタンなどの粘弾性体(気泡分散型遮音材)や、あるいは、小孔が多数貫設された薄肉のゴム板の両面を薄肉のゴム板で挟んだもの(気孔型遮音材)など、従来公知の様々な材料が使用可能である。
本実施の形態では、音響透過領域２２は、円筒部１６Ａ寄りの端部を除いた曲面部１６Ｂの全域となっており、図１に示す範囲θが、クジラや流木などのような前方の障害物を送受波器１４により探索する範囲となっている。 Further, the location of the sonar dome 16 constituting the sound insulation region 24 is constituted by a sound insulation material 34B in which the core material 34 insulates sound (including reduction of vibration noise). As such a sound insulation material 34B, a viscoelastic body (bubble dispersion type sound insulation material) such as rubber mixed with bubbles (glass microballoons) or polyurethane, or a thin rubber plate having many small holes penetrated. Various conventionally known materials can be used, such as a material in which both surfaces are sandwiched between thin rubber plates (a pore type sound insulating material).

This is a range in which the object is searched by the transducer 14.

本実施の形態によれば、型により一体成形されたソナードーム１６の一層のコア材３４により、音響透過領域２２と遮音領域２４とが区画されるので、従来のように、面倒な遮音材３４Ｂの貼り付け作業を省略し、ソナードーム１６を効率よく製造する上で有利となる。
また、コア材３４の外面は、外側部材３２により保護されているため、航海中にコア材３４が剥がれることもなく、耐久性に優れる。
また、遮音材３４Ｂを貼り付けることがないため、遮音材３４Ｂの厚み分、ソナードーム１６と送受波器１４との間隔が狭められることもなく、送受波器１４の性能を確保する上で有利となる。 According to the present embodiment, since the sound transmission region 22 and the sound insulation region 24 are partitioned by the one-layer core material 34 of the sonar dome 16 integrally formed by the mold, the troublesome sound insulation material 34B as in the conventional case is used. This is advantageous in efficiently manufacturing the sonar dome 16.
Further, since the outer surface of the core material 34 is protected by the outer member 32, the core material 34 is not peeled off during the voyage, and the durability is excellent.
In addition, since the sound insulating material 34B is not attached, the distance between the sonar dome 16 and the wave transmitting / receiving device 14 is not reduced by the thickness of the sound insulating material 34B, which is advantageous in securing the performance of the wave transmitting / receiving device 14.
