【産業上の利用分野】
この発明は、送受波器保護装置の構造及び送受波器保護装置の製造方法に係わり、更に詳しくは観測船等の船首側下部に形成された空洞部に設置される送受波器(音響センサー)を自船等から発生する雑音から有効に保護するゴム製のソナードーム本体を構成する送受波器保護装置の構造及び送受波器保護装置の製造方法に関するものである。
【0002】
【従来の技術】
従来、観測船等に装備される送受波器(音響センサー)を保護するゴム製のソナードームは、音響性能を向上させるために、船底に取り付けられる,所謂キールドームタイプから船首に取り付けられる,所謂バウドーム型へと変化してきている。即ち、自船等から発生するエンジン音や振動、その他の機器類及びプロペラから発生する水中雑音の影響を少なくするために、図2及び図3に示すように船体1の船首2側に取り付ける傾向にある。
【0003】
このように船首2側に送受波器3を保護するゴム製のソナードーム4を取り付ける傾向に伴い音響透過損失の小さいドーム本体部5が船首2側に大きく前方に張り出した構造となり、船体1から発生する雑音Qに対して無防備の状態となっている。
【0004】
【発明が解決しようとする問題点】
ところで、船体1から発生する雑音Qが送受波器3に入射して来る雑音Qに対して、図4に示すようにドーム本体部5の内側にタイル状の遮音材6を貼付ける方法もあるが、ドーム本体部5の曲率Rに合わせて遮音材6を貼付けるのが難しく、施工作業性が悪い上、また取り付けた遮音材6が短期間に剥離する危険性を考えられ、改善の余地があった。
【0005】
この発明は、かかる従来の問題点に着目して案出されたもので、ドーム本体部に対して遮音材を容易に施工でき、短期間に剥離すると言う問題もなく、遮音性能及び耐久性に優れた送受波器保護装置の構造及び送受波器保護装置の製造方法を提供することを目的とするものである。
【0006】
【課題を解決するための手段】
この発明は、上記目的を達成するため、この発明の送受波器保護装置の構造は、ソナードーム本体は、補強層を埋設した内層ゴムと、厚み調整ゴムを隔てて配設した外層ゴム層とからなり、前記送受波器の測定範囲以外の肉厚の厚いゴム部分で、かつゴム製のソナー ドーム本体中にゴム製のタイル状の遮音材を加硫成形時に一体的に埋設したことを要旨とするものである。
【0007】
また、この発明の送受波器保護装置の製造方法は、補強層を埋設した防汚ゴムから成る内層ゴムと、厚み調整ゴムを隔てて配設された防汚ゴムから成る外層ゴム層とでソナードーム本体を構成する送受波器保護装置の製造方法であって、送受波器の測定範囲以外の部分の前記厚み調整ゴムに、予めタイル状に形成した遮音材を埋設し、前記ソナードーム本体の加硫成形時に一体的に成形することを要旨とするものである。
【0008】
【発明の作用】
この発明は、上記のように構成され、船体から入射してくる雑音を反射させ、ソナードーム内の雑音を低減させる遮音材をゴム製のタイル状に形成し、このタイル状の遮音材をソナードーム本体の製作時、即ち、送受波器の測定範囲以外の部分の内層ゴムに遮音材を配設し、加硫時に一体的に埋設して成形することにより、施工作業性及び剥離等の問題を解決出来るものである。
【0009】
【発明の実施例】
以下、添付図面に基づきこの発明の実施例を説明する。
なお、従来例と同一構成要素は、同一符号を付して説明は省略する。
図1は、この発明を実施した送受波器保護装置10の一部拡大断面図を示し、船首2側下部に形成された空洞部11には送受波器12が設置され、この空洞部11を覆うようにゴム製のタイル状に形成した遮音材13を埋設したゴム製のソナードーム本体14が船体に取付けてある。
【0010】
前記ソナードーム本体14は、ワイヤー等を束ねた補強層15を埋設した防汚ゴムから成る内層ゴム16と、厚み調整ゴム17を隔てて配設された防汚ゴムから成る外層ゴム層18とから構成され、前記補強層15の端末部におけるビート部15aは、船体への取付け金具1にクランプ1aを用いて固定されている。
前記送受波器12の測定範囲X以外の部分Zの厚み調整ゴム17には、前記タイル状に形成した遮音材13が埋設され、この遮音材13は、前記送受波器12の測定範囲X以外の部分の肉厚の厚い厚み調整ゴム17の部分に配設して、加硫時に一体的に成形されるものである。
【0011】
このように、ゴム製のタイル状に形成した遮音材13は、ソナードーム本体14の成形時に予め送受波器12の測定範囲X以外の部分Zの肉厚の厚い厚み調整ゴム17の部分に配設しておき、加硫成形時に一体的に成形することで、後に貼付けたりする作業が省略でき、また使用時に剥離して脱落することもなく、耐久性も良好なものとなる。
更に、遮音材13は厚み調整ゴム17内に埋設されるので、表面の平滑性の確保も可能となるものである。
【0012】
【発明の効果】
この発明は、上記のように送受波器の測定範囲以外の部分の前記厚み調整ゴムに、予めタイル状に形成した遮音材を埋設し、前記ソナードーム本体の加硫成形時に一体的に成形するので、ドーム本体部に対して遮音材を容易に施工でき、施工作業性を良好にすることが出来ると共に、短期間に剥離すると言う問題もなく、遮音性能及び耐久性に優れたものとすることが出来る効果がある。
