この発明は円筒形水中音響受波器に関し、特にこれを多
数一列に連結して曳航する場合に有利な構造に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cylindrical underwater acoustic receiver, and particularly to a structure that is advantageous when a large number of cylindrical underwater acoustic receivers are connected in a row and towed.
水中音響を聴取するため、円柱形の水中音響受波器を可
撓性プラスチックよりなるホース状のジャケット内に数
十個収納して曳航することがある。In order to listen to underwater sound, dozens of cylindrical underwater sound receivers are sometimes housed in a hose-shaped jacket made of flexible plastic and towed.
このジャケットは、電線及び水中音響受波器の保護と、
所望の曳航深度を維持するために比重調整用の油その他
の物質を充填するものの覆いに用いられる。This jacket protects electric wires and underwater acoustic receivers,
Used to cover a fill with gravity-adjusting oil or other material to maintain the desired towing depth.
この場合、曳航時の張力を負担する強度メンバーや電線
が水中音響受波器の外側をとりまくような構造にすると
、前記ジャケットの径が犬となり、取扱い上種々の支障
を生ずる。In this case, if the structure is such that the strength members and electric wires that bear the tension during towing surround the outside of the underwater acoustic receiver, the diameter of the jacket becomes too large, causing various problems in handling.
本発明の目的はかかる問題を解決した円筒形水中音響受
波器を提案するにある。An object of the present invention is to propose a cylindrical underwater acoustic receiver that solves this problem.
以下本発明の実施例を図面を参照して説明する。Embodiments of the present invention will be described below with reference to the drawings.

の受波器１を数珠状に連結し、これらを可撓性プラスチ
ックよりなるホース状のジャケット８内に収納して水中
を矢印方向に曳航する。A rope-like bundle 7, which is a bundle of electric wires 6 for the receiver 1 and preamplifier, and a strength member, is inserted into the tube 3, and a large number of receivers 1 are connected to this in a beaded shape. is housed in a hose-shaped jacket 8 made of flexible plastic and towed underwater in the direction of the arrow.
圧電変換素子２、管３、及び端板４にて囲まれた空間は
圧電変換素子２が音圧変化に従って忠実に振動するよう
気密室９とする。A space surrounded by the piezoelectric transducer 2, the tube 3, and the end plate 4 is an airtight chamber 9 so that the piezoelectric transducer 2 vibrates faithfully in accordance with changes in sound pressure.

のために増大させる必要がなくなって取扱いが便利にな
る等の効果がある。The present invention has the above configuration, in which the piezoelectric transducer is formed into a cylindrical shape, a tube is fixedly supported in the internal cavity, and a towing strength member and electric wires are passed through the tube in the form of a bundle, so that the piezoelectric transducer is all effectively serve as wave receiving surfaces, and the electric wires can be arranged compactly in the center, making it easier to handle since there is no need to increase the inner diameter of the hose-like jacket that houses the piezoelectric transducer to accommodate the electric wires. It has the effect of making it more convenient.
