BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an
apparatus for storing a vertical sensor array used in the sea.
[0002]
2. Description of the Related Art FIG. 4 is a longitudinal sectional view showing the construction
of a conventional storage device of this type of vertical sensor array, and FIG. 5 is an explanatory
view of the expansion process of the vertical sensor array in use.
[0003]
In the figure, reference numeral 1 denotes a bottomed external cylinder or cylinder having an
opening 1a at its upper end, and an electronic circuit 2 which is connected by a cable and is
sequentially fed out from the upper end opening 1a at the time of sedimentation. The array unit
3, the central sensor package 4, the second array unit 5, and the weight 6 are accommodated,
and the electronic circuit 2 positioned at the top is connected to the suspension cable 7.
The direction perpendicular to the central axis A (the axis perpendicular to the axis of the array
section at the time of expansion) on one side 4 a of the central sensor package 4, that is, on the
part to be the upper surface under the state accommodated in the exterior cylinder 1 A pair of
hooks 8 and 9 to which the cables of the array units 3 and 5 are respectively connected are

provided at a predetermined distance from each other. That is, since the central sensor package 4
contains therein a sensor for detecting the orientation and the like, and in use it is necessary to
keep the vertical direction with respect to the array unit axis, the spans of the hooks 8 and 9 are
made as wide as possible. Is preferred. For this reason, the hooks 8 and 9 are disposed at both
ends of one side surface 4 a (upper surface) of the central sensor package 4. Reference numeral
11 denotes a bottomed stepped cylindrical case having an opening at the upper end
accommodated in the exterior cylinder 1 and housing the weight 6, the second array unit 5, the
central sensor package 4, and the first array unit 3 from the bottom. And the electronic circuit 2
is mounted on the upper end.
[0004]
In such a thing, in order to expand the vertical sensor array, the suspension cable 7 is retained
from the sea surface, and the exterior cylinder 1 is allowed to sink into the sea (state a in FIG. 5).
The vertical sensor array has the upper part supported by the suspension cable 7 and the lower
part 6 is connected to the lower part, so the electronic circuit 2, the first array part 3, and the
central sensor from the upper end opening 1 a according to the sedimentation of the outer
cylinder 1 When the package 4 is sequentially drawn out (state b of FIG. 5) and finally the weight
6 is drawn out and separated from the outer cylinder 1, tension of the first and second array
portions 3 and 5 which receive the load of the weight 6 The central axis A of the central sensor
package 4 is rotated by 90 ° from the time of storage and kept in the direction perpendicular to
the array axis (the state of c in FIG. 5). Then, in the first and second array units 3 and 5 and the
central sensor package 4, the tension due to the load of the weight 6 suppresses the oscillation
due to the current.
[0005]
In the conventional vertical sensor array storage device, each device connected by a cable in the
exterior cylinder 1 is vertical while being drawn out from the upper end opening portion 1a as
described above at the time of sedimentation. The central sensor package 4 is pulled up with a
position away from the center of the one side surface 4a (upper surface) as a fulcrum, so it
moves from the case 11 inside the exterior cylinder 1 while being given a rotational force M.
Therefore, the central sensor package 4 comes in contact with the inner wall of the case 11 and
the exterior cylinder 1 at the time of movement, and is pulled up with friction. As a result, the
suspension cable 7 is subjected to an excessive load, which causes disconnection or In the
exterior cylinder 1 where the amount of movement is large, there is a problem that the hooking
occurs and the extension is impossible.

[0006]
Such a problem can be solved by setting the inner diameter of the outer cylinder 1 to a size that
can absorb the swing of the central sensor package 4, but in this case the device is not only
enlarged but also with each device. Since the gap with the inner wall of the outer cylinder 1
becomes large, it is necessary to be able to easily feed out while making the interference
prevention means embedded in the gap firm, and the weight of the weight 6 is further increased
as the buoyancy increases. In addition, the strength of the cable is also increased, and the
hanging means must also be increased in size, and the cost must be increased.
[0007]
SUMMARY OF THE INVENTION A storage device for a vertical sensor array according to the
present invention is provided with a pair of detachable half sleeves surrounding at least a central
sensor package in an outer cylinder and each half sleeve This is provided with an inward half
flange formed at the axial center portion with a notch serving as a through hole of the cable of
the first array portion above the central sensor package when these are combined.
In the present invention, at the time of delivery of each device due to sedimentation of the outer
cylinder, the central sensor package can be pulled up integrally with the pair of half sleeves and
with the center of one side surface (upper surface) as a fulcrum. There is no generation of force
or friction, and it moves smoothly inside the outer cylinder. When both the central sensor
package and the pair of half sleeves integrally moving with it are completely fed out from the
outer cylinder, the pair of half sleeves loses the restraining force from the outer cylinder and the
inner sleeve The rotational movement of the central sensor package forces the central sensor
package to be released. That is, the pair of half sleeves function as a slider when the central
sensor package is fed out, and prevent direct contact and friction between the central sensor
package and the inner wall of the outer cylinder to prevent a cable breakage accident.
[0008]

above-mentioned conventional example (Drawing 4 and Drawing 5).
[0009]
In the vertical sensor array storage device according to the present embodiment, a pair of
detachable thin half sleeves 21 and 22 surrounding the central sensor package 4 is provided in
the bottomed outer cylinder 1 which is an outer cylinder. And in each of the half sleeves 21 and
22, at the center in the longitudinal direction, the notches 21a and 22a which become through
holes of the cable of the first array portion 3 above the central sensor package when the two are
put together The first array portion 3 is provided in the upper chamber 23 defined in the
respective half sleeves 21 and 22 by providing the inward half flanges 21b and 22b formed in
the respective portions and the respective half flanges 21b and 22b. , And the central sensor
package 4 is accommodated in the lower chamber 24, and the cable of the first array portion 3 is
one side of the central sensor package 4 through the hole 25 formed by the notches 21a and
22a. The cable of the second array section 5 is connected to the other hook 8 through the gap
between the central sensor package 4 and the half sleeve 21 while being connected to one hook
9 of 4a (upper surface) is there.
[0010]
Further, an outward flange 4 b to which the lower ends 21 c and 22 c of the half sleeves 21 and
22 can abut is provided at a position to be a lower end in the outer cylinder 1 of the central
sensor package 4. The half sleeves 21 and 22 are placed on the flange 4 b of the central sensor
package 4.
It is needless to say that a notch (not shown) for passing the cable of the second array section 5
is formed in a part of the flange 4b.
[0011]
Furthermore, a short-ended bottomed cylindrical case 11A having an opening at the upper end is
disposed at the bottom of the exterior cylinder 1, and the weight 6 and the second array portion
5 are accommodated in the case 11A from the bottom and the upper end On which the central

example described above.
[0012]
In the storage device of the vertical sensor array according to the present embodiment, when the
hanging cable 7 is retained from the sea surface and the outer cylinder 1 is made to sink into the
sea, first the electronic circuit 2 and the first array portion 3 are delivered in order from the
outer cylinder 1 (State a in FIG. 3). Then, the central sensor package 4 and the respective half
sleeves 21 and 22 placed on the flange 4 b thereof are integrated, and the first array portion 3
with the central portion of one side surface 4 a (upper surface) of the central sensor package 4 as
a fulcrum The inside of the outer cylinder 1 is pulled up by the cable of (1) in FIG. Then, when
both the central sensor package 4 and the respective half sleeves 21 and 22 integrally moving
with the central sensor package 4 are completely drawn out from the inside of the outer cylinder
1, the half sleeves 21 and 22 have the restraining force from the outer cylinder 1 Further, the
central sensor package 4 is forcibly released from the central sensor package 4 by the rotational
movement of the central sensor package 4 (state c in FIG. 3). Although c in FIG. 3 shows a state
in which the half sleeves 21 and 22 are detached before the central sensor package 4 performs
the rotation operation, this is a normal detachment operation, and c in FIG. Because no restraint
force acts on each of the half sleeves 21 and 22 even if detachment is not started at the position,
when the central sensor package 4 starts to rotate, the rotational force of the central sensor
package 4 makes it easy It goes without saying that it is possible to make sure that the Finally,
when the weight 6 is drawn out and separated from the exterior cylinder 1, the central axis B of
the central sensor package 4 is 90 ° from the time of storage due to the tension of the first and
second array portions 3, 5 receiving the load of the weight 6. It rotates and is kept perpendicular
to the array unit axis (state d in FIG. 3). Then, in the first and second array units 3 and 5 and the
central sensor package 4, the tension due to the load of the weight 6 suppresses the oscillation
due to the current.
[0013]
As described above, in the storage device of the vertical sensor array according to the present
embodiment, the central sensor package 4 is integrated with the half sleeves 21 and 22 and one
side surface 4 a Since the inside of the exterior cylinder 1 can be pulled up with the central
portion of the upper surface as a fulcrum, no rotational force or friction is generated, and the
inside of the exterior cylinder 1 can be smoothly moved. That is, each half sleeve 21 and 22
functions as a slider when the central sensor package 4 is delivered, and prevents direct contact
and friction between the central sensor package 4 and the inner wall of the exterior cylinder 1 to

[0014]
Further, the half flanges 21b and 22b are respectively set at the longitudinal central portions of
the half sleeves 21 and 22, and are defined in the half sleeves 21 and 22 by the half flanges 21b
and 22b. Since the first array portion 3 is accommodated in the upper chamber 23 and the
central sensor package 4 is accommodated in the lower chamber 24, the length of each of the
half sleeves 21 and 22 functioning as a slider is The length can be set long without changing the
total length, which can enhance the slider function.
[0015]
In addition, an outward flange 4b to which the lower ends 21c and 22c of the half sleeves 21 and
22 can abut is provided at a position to be the lower end in the outer cylinder 1 of the central
sensor package 4, and each half on the flange 4b Since the split sleeves 21 and 22 are mounted,
the axial position of each of the half sleeves 21 and 22 can be defined by the flange 4b, and the
positional deviation of the joint portion between the half flanges 21b and 22b can be determined.
It can be prevented.
[0016]
In the above embodiment, the half sleeves 21 and 22 are set to a length that can also
accommodate the first array portion 3 to improve the slider function. The split sleeves 21 and 22
may have a length that can accommodate the central sensor package 4, and the intended
purpose can be achieved.
[0017]
As described above, according to the present invention, a pair of detachable half sleeves which at
least surround the central sensor package are provided in the outer cylinder, and these half
sleeves are combined with each other. In this case, since the inward half flange provided with the
notch portion which becomes the through hole of the cable of the first array portion above the
central sensor package is formed at the axial center portion, the pair of half sleeves It functions
as a slider at the time of package delivery, and prevents direct contact and friction between the
central sensor package and the inner wall of the outer cylinder, thereby preventing cable
disconnection accident in advance.
