本発明は水中センサー（振動計、深度計等）の吊り下げ
装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hanging device for underwater sensors (vibration meters, depth meters, etc.).
従来、水中センサーの吊り下げ装置は、波浪による動揺

り扱いが不便なものであった。Conventional underwater sensor hanging devices have the disadvantage of being large because they require a structure to reduce vibrations caused by waves, etc., and are therefore inconvenient to handle when not in use. Ta.
そこで、本発明は上記の欠点を解決するもので、水中浮

中センサーの吊り下げ装置を得ることを目的としたもの
である。Therefore, the present invention is intended to solve the above-mentioned drawbacks, and a hanging body formed by connecting an appropriate number of drag anchors via a flexible connecting body is attached to the end of a hanging cable connected to an underwater floating body. , by storing an underwater sensor in the hanging body,
The object of the present invention is to provide a hanging device for an underwater sensor that can be folded into a small size when not in use, and can reduce vibrations caused by waves when in use.
次に本発明の一実施例を図面に従って説明すると、適宜
数のドラグアン力（円形板、湾曲板、網等）１を目の細
かい網状（紐状）の可撓性連結体２を介して適宜間隔に
連結して吊下体３を形成する。Next, an embodiment of the present invention will be described with reference to the drawings. An appropriate number of drag pull-in forces (circular plates, curved plates, nets, etc.) 1 are applied via a fine mesh (string-like) flexible connecting body 2. A hanging body 3 is formed by connecting at intervals.
そして、この吊下体３の連結状態は、水中センサー４を
収納するドラグアフカ１間の可撓性連結体２を筒状とし
、他のドラグアフカ１間の可撓性連結体２を十文字（−
文字等でも良い）とするものである（第２図、第３図）
。The connected state of the hanging body 3 is such that the flexible connecting body 2 between the drag africans 1 that accommodate the underwater sensor 4 is cylindrical, and the flexible connecting body 2 between the other drag africans 1 is shaped like a cross (-
(Characters, etc. may also be used) (Figures 2 and 3)

次に、該吊下体３の一端を、中間にスプリング部５を設
けた吊下索（ケーブル）６の一端に取り付け、更に該吊
下索６の他端を水中浮遊体７に取り付けて形成したもの
である。Next, one end of the hanging body 3 was attached to one end of a hanging cable (cable) 6 having a spring portion 5 in the middle, and the other end of the hanging cable 6 was attached to an underwater floating body 7. It is something.
斯様な構成は、吊下体３がドラグアンカ１と可撓性連結
体２とによって形成されている為に使用時以外は小さく
畳むことが出来るものである（第３図）。In such a configuration, since the hanging body 3 is formed by the drag anchor 1 and the flexible connecting body 2, it can be folded into a small size when not in use (FIG. 3).
そして、使用時（第１図）、つまり水中に吊り下げると
可撓性連結体２は伸張するもので、該可撓性連結体２の
十文字等に設けた部分は、吊下索６の捩れ等による回転
や潮流等による横方向の流れによる回転を防止するもの
である。When in use (FIG. 1), that is, when suspended in water, the flexible connecting body 2 stretches, and the cross-shaped parts of the flexible connecting body 2 are designed to prevent twisting of the suspension cable 6. This is to prevent rotation due to lateral flow due to tidal currents, etc.
又、水中センサー４を収納した部分の可撓性連結体２、
つまり筒状に設けた可撓性連結体２は、潮流等の横方向
の流れに対する抵抗を柔らげて雑音が発生するのを防止
すると共に該可撓性連結体２内の水量は付加質量となる
。In addition, the flexible connecting body 2 of the part that houses the underwater sensor 4,
In other words, the flexible connecting body 2 provided in a cylindrical shape softens the resistance to lateral flows such as tidal currents and prevents the generation of noise, and the amount of water inside the flexible connecting body 2 is reduced by the additional mass. Become.
更に、夫れ夫れのドラグアンカ１は液体（海水等）の付
加質量を生じさせ、又付加質量はドラグアンカ１の数に
比例して増加するものである。Furthermore, each drag anchor 1 generates an additional mass of liquid (seawater, etc.), and the additional mass increases in proportion to the number of drag anchors 1.
そこで、吊下索６にスプリング部５が設けであるので、
上記吊下体３の動き量は、吊下体（７）動＠波の高さ

波の周波数ｆ
吊下体。Therefore, since the suspension cable 6 is provided with the spring part 5,
The amount of movement of the above-mentioned suspended body 3 is determined by the vertical axis X, which is the transmissibility of the suspended body (7) due to the movement @ wave height, and the wave frequency f suspended body.
固有振動数、。ヲ横軸ｙ トＬ Ｔ・０れを図で表わす

）。Natural frequency,. If the horizontal axis y and L T·0 are represented in a diagram, it will be as shown in FIG. 4 (a in the diagram is the resonance point and b is the attenuation region).
つまり、付加質量の増大によって吊下体の固有振動数ｆ
。In other words, due to the increase in the added mass, the natural frequency f of the suspended body

出来るものである。If the wave height is constant, f/fo becomes large and the amount of attenuation becomes large. Therefore, it is possible to prevent vibrations caused by waves from being applied to the underwater sensor.
以上の構成・作用を有する本発明によると、水中センサ

潮流等による雑音の発生も防止し得るものである。According to the present invention having the above-described structure and operation, since the drag force for attaching the underwater sensor is connected by a flexible connecting body, it can be folded into a small size when not in use, making it easy to handle. In addition, during use, the added mass of the hanging body increases, providing a good vibration-proofing effect and also preventing the generation of noise due to tidal currents and the like.
又、構造が簡単で且つ軽量である為に作業性が良く、更
に製作も安価となるものである。In addition, since the structure is simple and lightweight, it is easy to work with and is also inexpensive to manufacture.
