【考案の詳細な説明】
本考案は、ケース内に振動子を備えた水中用送
受波器に関するものである。[Detailed Description of the Invention] The present invention relates to an underwater transducer equipped with a vibrator inside a case.
第１図に従来の水中用送受波器の一例を示す。
同図の水中用送受波器は、蓋板１に固定されてい
る支持構造体２に振動子３を押え板７により取付
け固定し、絶縁油４を充填したケース５内に収納
した構造であつて、支持構造体２はネジ込などに
より蓋板１に固定され、振動子３は防振板８を介
して支持構造体２に固定されている。 FIG. 1 shows an example of a conventional underwater transducer.
The underwater transducer shown in the figure has a structure in which a vibrator 3 is attached and fixed to a support structure 2 fixed to a cover plate 1 by a presser plate 7, and housed in a case 5 filled with insulating oil 4. The support structure 2 is fixed to the cover plate 1 by screwing or the like, and the vibrator 3 is fixed to the support structure 2 via a vibration isolating plate 8.
ところで、上記従来の構造では、蓋板１、支持
構造体２、押え板７などの固有振動が防振板８を
通して振動子３に入り水中用送受波器の特性を著
しく悪化させる欠点があつた。 However, the conventional structure described above has the disadvantage that the natural vibrations of the cover plate 1, support structure 2, presser plate 7, etc. enter the vibrator 3 through the vibration isolation plate 8, significantly deteriorating the characteristics of the underwater transducer. .
特に深深度においては防振板８の防振効果が深
度と共に著しく低下し使用不能になる。 Particularly at deep depths, the vibration-proofing effect of the vibration-proof plate 8 decreases significantly as the depth increases, making it unusable.
上記欠点に対する対策は今までのところなされ
ていない。 No countermeasures have been taken so far for the above drawbacks.
本考案は、これらの欠点を除去し、良好なる計
測を行う水中用送受波器を提供しようとするもの
である。 The present invention aims to eliminate these drawbacks and provide an underwater transducer that can perform good measurements.
以下、本考案に係る水中用送受波器の実施例を
図面に従つて説明する。 Embodiments of the underwater transducer according to the present invention will be described below with reference to the drawings.
第２図において、水中用送受波器は、ゴムある
いはその他の材料からなるケース５の内部に発泡
ゴム、発泡プラスチツク等の緩衝性を有する発泡
体６を充塞し、この発泡体６の内に振動子３埋納
し、発泡体６そのものを支持構造体としたもの
で、この発泡体６に絶縁性液体としての絶縁油４
を含浸させて良好な音響媒体としたものである。 In FIG. 2, the underwater transducer has a case 5 made of rubber or other material filled with a foam 6 having cushioning properties such as foamed rubber or foamed plastic. The foam 6 itself is used as a support structure, and the foam 6 is coated with an insulating oil 4 as an insulating liquid.
It is made into a good acoustic medium by impregnating it with
上記実施例の構成によれば、振動子３は発泡体
６及び絶縁油４の内に浮いた構造となり他の固体
と直接触れることが無いので水中用送受波器とし
ての特性を悪化させる振動の影響を受けることが
無く構造も簡単になる。また、発泡ゴム、発泡プ
ラスチツク等の発泡体６は衝撃に対し緩衝性を有
するので衝撃に対し振動子３を保護する効果を有
している。また、発泡体６に絶縁油４を含浸させ
ることによつて良好な音響媒体として作用するか
ら充分な感度が得られる。 According to the configuration of the above embodiment, the vibrator 3 has a floating structure within the foam body 6 and the insulating oil 4, and does not come into direct contact with other solid bodies, so it is free from vibrations that deteriorate the characteristics as an underwater transducer. There is no influence and the structure becomes simpler. Further, the foam 6 such as foamed rubber or foamed plastic has a shock absorbing property, and therefore has the effect of protecting the vibrator 3 from shock. Further, by impregnating the foam 6 with the insulating oil 4, it acts as a good acoustic medium, so that sufficient sensitivity can be obtained.
以上説明したように、本考案によれば良好な水
中音波の計測が可能であつて、かつまた耐衝撃性
を具備した水中用送受波器を得ることができる。 As described above, according to the present invention, it is possible to obtain an underwater transducer that can measure underwater sound waves with good quality and is also shock resistant.
