【発明の詳細な説明】 〔産業上の利用分野〕 この発明は、水中防振遮音台の整流覆いの構造に係わ
り、更に詳しくは構造が簡単で、しかも組付け作業性を
良好にした水中防振遮音台の整流覆いの構造に関するも
のである。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rectifying cover structure for an underwater vibration-proof and sound-insulating stand, and more particularly, to a submersible hood with a simple structure and good assembling workability. The present invention relates to a structure of a rectifying cover of a vibration isolation stand.
一般に、船等に取付けて使用する水中音響機器類の受
波器は、船体の振動及び放射音の影響を避けるために、
遮音機能を有する防振台に取付ける必要がある。In general, receivers for underwater acoustic equipment mounted on ships, etc., should be used to avoid the effects of hull vibration and radiated sound.
It must be installed on a vibration isolator with sound insulation.
防振機構を構成する表面板は、スプリング等のバネに
より支えられているが、水中で使用する場合には、表面
板と船体との間の水の影響によってバネは機能しなくな
り、防振機構は成り立たなくなる。また、この水を通し
て音波が船体から表面板の表面に透過し、表面板上の受
波器に妨害を与えると言う問題がある。The surface plate constituting the anti-vibration mechanism is supported by a spring such as a spring. However, when used underwater, the spring does not function due to the effect of water between the surface plate and the hull, and the anti-vibration mechanism is used. Does not hold. Further, there is a problem that sound waves pass through the water from the hull to the surface of the face plate, and interfere with the receiver on the face plate.
ところで、従来一般的に使用されている防振機構とし
ては、例えば第２図に示すように水中で使用する架台ま
たは船体等の母台１に装着した相対向する一対の支持部
材２（支持金具）に、スプリング等のバネ３を介して受
波器４を設置した表面板５の両端部が取付けられてい
る。Conventionally, as a vibration isolating mechanism generally used, for example, as shown in FIG. 2, a pair of opposing support members 2 (support fittings) mounted on a base 1 such as a gantry or a hull used in water. ), Both ends of a surface plate 5 on which a wave receiver 4 is installed via springs 3 such as springs.
そして、母台１の振動は、支持部材２を通してバネ３
に伝達されるが、バネ３で支持されている表面板５は、
大気中での作動の場合には、この系の共振周波数以上の
周波数で、振動伝達率が所定の値となり、母台１の振動
は低減される。しかし、水中で作動させる場合には、表
面板５は、バネ３と、表面板５と母台１との間の水の二
つの弾性部材により支持された状態となるが、表面板５
と母台１との間の水は、硬いバネと考えることが出来る
ので、合成のバネは非常に硬いバネと等価となる。The vibration of the base 1 is transmitted to the spring 3 through the support member 2.
The surface plate 5 supported by the spring 3 is
In the case of operation in the atmosphere, at a frequency equal to or higher than the resonance frequency of the system, the vibration transmissibility becomes a predetermined value, and the vibration of the base 1 is reduced. However, when operated in water, the surface plate 5 is supported by the spring 3 and two elastic members of water between the surface plate 5 and the base 1, but the surface plate 5
The water between the base and the base 1 can be considered as a hard spring, so a synthetic spring is equivalent to a very hard spring.
従って、表面板５を支持する防振機構は上記のような
影響により作動しなくなる。Therefore, the anti-vibration mechanism that supports the front plate 5 does not operate due to the above-described influence.
この状態の時、表面板５を網状にすることで水の影響
を除去し、機構を正常に作動させることも可能ではある
が、母台１から放射された音波は、中間の水を通り直接
表面板５に達し、目的とする防振と遮音とを同時に成立
させることは困難である。In this state, it is possible to remove the influence of water by making the surface plate 5 mesh-like and to operate the mechanism normally. However, sound waves radiated from the base 1 directly pass through intermediate water. It is difficult to reach the surface plate 5 and simultaneously achieve the desired vibration isolation and sound insulation.
また、船体の外壁面のように、表面板５の上に流れが
生ずる場合には、受波器４に対する流れの影響を排除す
るために、更に整流覆い10を被せて構成したものもあ
る。Further, when a flow occurs on the surface plate 5 like the outer wall surface of the hull, there is also a configuration in which a rectifying cover 10 is further covered in order to eliminate the influence of the flow on the receiver 4.
また、従来の防振機構の他のものとしては、第３図に
示すようにバネの機能を備えた偏平中空管６を、ゴム等
の粘弾性体７で包み、粘弾性体７の外側に表面板８を取
付けて母台１に装着し、更に上記の従来例と同様に整流
覆い10を被せて構成したものも知られている。As another example of the conventional vibration isolating mechanism, as shown in FIG. 3, a flat hollow tube 6 having a spring function is wrapped in a viscoelastic body 7 such as rubber, There is also known a configuration in which a surface plate 8 is mounted on the base 1 and mounted on the base 1 and further covered with a rectifying cover 10 as in the above-mentioned conventional example.
然しながら、このような従来の整流覆い10にあって
は、受波器４を取付けた表面板５及び８とは、別体に構
成され、水中防振遮音台を母台１に組付けた後に、更に
整流覆い10を被せるように構成しているため、多くの手
間と時間を要し、更に受波器４と整流覆い10とは一定の
間隔を隔てて取付けられるために、母台１上の厚さが厚
くなると言う問題があった。However, in such a conventional rectifying cover 10, the surface plates 5 and 8 on which the receiver 4 is mounted are formed separately from each other, and after the underwater vibration-proof and sound-insulating table is assembled to the base 1, The rectifying cover 10 is further covered with the rectifying cover 10, so that much labor and time are required. Further, since the receiver 4 and the rectifying cover 10 are attached at a fixed interval, There is a problem that the thickness of the film becomes thick.
この発明は、かかる従来の問題点に着目して案出され
