Next, the damper accommodating portion 9 assembled as described above is mounted in the container. The damper accommodating portion 9 is inserted and incorporated into the outer cylinder 5 of the container. A gap 31 is formed between the inner surface of the outer cylinder 5 and the side surface of the damper housing portion 9, but since the tongue-shaped protrusions 29a and 29b project from the side surface of the damper housing portion 9, the assembly is incorporated. In this case, the tongue-shaped protrusions 29a, 29b

At this time, the holding member 30 remains fixed to the bottom of the damper housing portion 9, and the damper housing portion 9 remains fixed inside the container 2. When the container 2 reaches near the desired depth, all the hanging cables 4 in the cable housing 7 are paid out, and the cable housing 7 and the damper housing 9 are hung on this hanging cable 4. The container 2 is still attracted downwards by gravity. The gravity acting on the container 2 exceeds the elastic force and frictional force of the tongue-shaped protrusions 29a and 29b,
The container 2 further drops, and the cable storage 7 and the damper storage 9 are discharged.

Since the cable storage portion 7 and the damper storage portion 9 are released from the container 2, the tongue-shaped protrusions 29a and 29b are free. As a result, the tongue-shaped protrusions 29a, 29
b, the holding member 30 fixed to the damper storage portion 9 is also free. The container 2 continues to drop, and the suspension cable 4 between the damper 8 and the sensor 1 also becomes in a tension state, and the sensor 1 is suspended.

Gravity acting on the sensor 1 acts via the suspension cable 4, pulls the damper 8 downward, and separates the damper 8 and the holding member 30 from the damper accommodating portion 9. As a result, the ring members 12a, 12 attached to the damper 8
Since b is also free, the folded damper 8 is largely expanded by this elastic force, and the original function of the damper 8 is exhibited.

Further, since the container 2 continues to drop, the sensor 1 is also pulled out of the container 2, and the container 2 is suspended below the sensor 1 by the suspension cable 4 connecting the sensor 1 and the container 2. Become. In this state, the sensor 1 functions. As described above, since the present embodiment has a simple structure, the deploying operation is reliably performed, and the reliability of the damper holding structure of the ocean sensor is improved.

In the present embodiment, the hanging cable 4 is stored in the cable storage portion 7, but a method of winding it around another winding frame and storing it in the container 2 may be used instead. A second embodiment according to the present invention will be described below with reference to the drawings. 9 is a perspective view showing a damper housing portion and a holding member of this embodiment, FIG. 10 is a perspective view showing a mounting state of the holding member, and FIG. 11 is a sectional view taken along line CC of FIG.

In the figure, reference numeral 9 denotes a damper housing portion, which is characterized by having a cylindrical shape and having a top plate 25. A suspension cable storage portion (not shown) is formed on the upper portion of the damper storage portion 9 and is integrated. In the center of the top plate 25,
There is a hole 26 for passing a suspension cable (not shown). Three
Reference numerals 2a, 32b, 32c, and 32d are locking holes provided on the side surface of the damper housing portion 9.

Reference numeral 33 denotes a holding member which is a plate-like lid made of elastic resin or metal. This is for covering the opening at the bottom of the damper accommodating portion 9, but a notch 34 is provided so that a gap for passing the hanging cable can be formed even when fitted in the opening. 4 for holding member
Locking protrusions 33a, 33b, 33c, 33d are provided at various places, and these are provided in the holes 32a, 32b of the damper housing portion 9,
It can be fitted with 32c and 32d.

Although the locking projections of the holding member and the locking holes of the damper accommodating portion 9 are described as four sets, any number of sets may be used as long as they can be securely fitted and removed. Next, an example of a procedure for housing the damper in the damper housing portion 9 will be described. First, although not shown, the cable storage unit / damper storage unit 9, the damper, the sensor, and the container are sequentially connected to the suspension cable that is unloaded from the floating body from the top.

The damper used here may be the same as that of the first embodiment. The damper configured as described above is stored in the damper storage portion 9. At this time, the hanging cable (not shown) unloaded from the floating body (not shown) is the hole 26 of the top plate 25.
Will pass through. Then, the holding member 33 is bent and press-fitted from the opening at the bottom of the damper housing portion 9 housing the damper 8, and the locking projections 33a, 33b, 33c of the holding member 33,
33d is a locking hole 32a, 32b, 32 of the damper housing portion 9
The holding member 33 is fixed so as to cover the opening at the bottom of the damper accommodating portion 9 by fitting with the c and 32d.

At this time, the suspension cable is lowered from the gap formed between the opening and the holding member 33. Although not shown, the damper housing portion 9 assembled in this way is housed in a container together with the ocean sensor. An ocean sensor structure is constructed using the components assembled as described above. The developed state and operation will be described below with reference to the drawings.

FIG. 12 is a diagram showing a state immediately after the start of dropping, FIG. 13 is a diagram showing a state immediately before the completion of suspension, and FIG. 14 is a diagram showing a suspension completed state. In the figure, 1 is an ocean sensor, and 2 is a container for accommodating the sensor 1. 3 is a floating body such as a buoy, and 4 is a suspension cable connecting the floating body 3 and the sensor 1. Also,

The container 2 is a floating body 3 until the sensor 1 is used.
It is attached to the lower part of the floating body 3 at the time of use, but is discharged into the sea from the floating body 3 by means not shown. The container 2 falls due to its own weight, and the hanging cable 4 is attached to the container 2 accordingly.
The cables are sequentially fed out from the cable storage portion 7 inside.
At this time, the holding member 33 is fixed to the damper storage portion 9, and the damper storage portion 9 remains stored in the container 2.

When the container 2 reaches near the desired depth,
The suspension cables 4 in the cable storage unit 7 are all fed out, and the cable storage unit 7 and the damper storage unit 9 are suspended by the suspension cables 4, but the container 2 is still pulled downward by gravity. For this reason, the container 2 further falls and the damper storage portion 9 is discharged. The damper accommodating portion 9 is released from the container 2 and is suspended, but the container 2 continues to drop, and the damper 8 and the sensor 1 are suspended.
The suspension cable 4 between them also becomes in a tension state, and the sensor 1 is suspended.

Since the gravity applied to the sensor 1 acts via the suspension cable 4 and pulls the damper 8 downward, the holding member 33 fitted in the damper accommodating portion 9 is deformed by receiving a force, and the locking projection is damped. It is disengaged from the locking hole provided in the storage section 9. As a result, the damper 8 and the holding member 33 are separated from the damper accommodating portion 9. As a result, the ring members 12a and 12b attached to the damper 8 are also free, so that the elastic force causes the folded damper 8 to largely expand, and the original function of the damper 8 is exhibited.

Although the container 2 continues to drop, since the lowermost end of the suspension cable 4 is connected, the container 2 is suspended below the sensor 1 after the sensor 1 is opened. In this state, the sensor 1 can function stably. As described above, since the present embodiment has a simple structure, the deploying operation is reliably performed, and the reliability of the damper holding structure of the ocean sensor is improved.

In the present embodiment as well, the hanging cable 4 is stored in the cable storage portion 7, but instead of this, a method of winding it around a winding frame or the like and storing it in the container 2 is used. Is also possible.
