[0004]
In the conventional line array receiver 1 configured as above, first, the cable 3 between the
weight 6 and the lowermost receiver 4a is wound, for example, in the left-handed direction
around the outer periphery of the cylindrical portion 8 of the storage tray 7a. The lowermost
wave receiver 4a is housed in the weight 6 and housed in the cylindrical portion 8 of the storage
tray 7a. Next, the cable 3 between the lowermost receiver 4a and the receiver 4b in the next
higher stage is wound around the outer periphery of the cylindrical portion 8 of another storage
tray 7b, for example, in the right winding direction. While being stacked on the storage plate 7 a
in which the wave receiver 4 a is stored, the weight is accommodated in the weight 6. Then, the
receiver 4b is accommodated in the cylindrical portion 8 of the stacked storage tray 7b. Next, the
receivers 4c and 4d are also housed in the weight 6 as described above while the winding
direction of the cable 3 is left-handed and the right-handed winding and the housing plates 7c
and 7d are changed, and the weight 6 is housed in the outer case 10. . Then, the underwater
electronic unit 5 is accommodated in the outer case 10 so as to abut on the upper end portion of
the weight 6, and as shown in FIG. 6A, the accommodation of the line array receiver 1 is
completed.
[0005]
As shown in FIGS. 6 (b), (c) and (d), the line array receiver 1 of the storage completion is
sequentially extended with the cable 3 while the receivers 4a, 4b, 4c and 4d are lowered in
water. The storage trays 7a, 7b, 7c and 7d are detached from the cable 3 and descend with the
exterior case 10 as unnecessary items.
[0006]
SUMMARY OF THE INVENTION In the conventional line array receiver 1 as described above, the
cable 3 is wound around each of the storage trays 7a, 7b, 7c, 7d so that the cable 3 is not twisted
during expansion. The direction is reversed left and right and wound around the outer periphery
of the cylindrical portion 8, and the receivers 4a, 4b, 4c and 4d are accommodated in the
respective storage trays 7a, 7b, 7c and 7d and accommodated in the weight 6, It is
accommodated in the exterior case 10 and storage is completed.
However, since the work of winding the cable 3 around the respective storage trays 7a, 7b, 7c,
04-05-2019

7d is manually performed, changing the winding direction for each of the storage trays 7a, 7b,
7c, 7d is troublesome, time-consuming and time-consuming And cost increase was inevitable. In
addition, there is a possibility that the winding direction of the cable 3 may be made the same by
mistake because it is manual work, and if made the same, the cable 3 is twisted at the time of
expansion, causing breakage of the coating of the cable 3 or disconnection of the cable core.
There is also a fear that the original function of the marine sensor can not be obtained and the
reliability is impaired.
[0007]
The present invention has been made to solve the problems as described above, and it is possible
to perform storage operation and expansion easily and reliably with a simple structure, a line
that is reliable and avoids cost increase. The present invention provides a storage structure for an
array receiver.
[0008]
SUMMARY OF THE INVENTION The storage structure of a line array receiver according to the
present invention has a cylindrical weight with a bottom at the end of a cable, and a plurality of
receivers are connected in series to this cable. And the line array receiver in which the wave
receiver is expanded as it descends into the water, the cylindrical portion in which the wave
receiver of the line array receiver is accommodated and the cable is wound around the outer
periphery, and the lower end of the cylindrical portion And an outer case in which a weight in
which a storage plate containing a wave receiver is stacked and stored is stored, and a protrusion
is formed on the outer periphery of the cylindrical portion of the storage plate. Of the line array
receiver between the receivers of the line array receiver or between the receiver and the weight
by hooking an intermediate point that divides the cable into two roughly equal parts, Is wound
around the outer periphery of the cylindrical portion.
[0009]
As a result, the winding directions of the cables folded back into two are reversed at the midpoint
where the cable is approximately bisected, and a storage structure of the line array receiver
which does not cause twisting when stretched is obtained.
[0010]
DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is an enlarged view of the main part of
an embodiment of the present invention.

The same parts as those in the conventional example described with reference to FIG.
In the figure, reference numeral 11 denotes a projection provided substantially at the center in
the height direction of the outer periphery of the cylindrical portion 8 of the storage trays 7a, 7b,
7d, 7d. In the case of winding around the outer periphery, as shown in FIG. 2 (a), for example, the
midpoint 3a that approximately bisects the cable 3 between the receivers 4a and 4b of the line
array receiver 1 is hooked. It becomes a winding start point of the cable 3 which is folded back
and wound around the outer periphery of the cylindrical portion 8.
Reference numeral 12 denotes a notch provided at the upper end of the cylindrical portion 8 and
the outer edge of the disc 9 for guiding the cable 3 wound around the cylindrical portion 8 to the
inside or the outside of the cylindrical portion 8 or the like.
[0011]
In this embodiment configured as described above, when the line array receiver 1 is stored, first,
as shown in FIG. 2A, for example, the cable 3 between the receiver 4a and the receiver 4b is
used. As shown in FIG. 2B, the storage plate 7b is rotated in the direction of arrow A, as shown in
FIG. 2C, as shown in FIG. 2C. The cable 3 is wound around the outer periphery of the cylindrical
portion 8 of the storage tray 7b, and the wave receiver 4b is accommodated in the cylindrical
portion 8 of the storage tray 7b. At this time, as shown in FIG. 3, in the cable 3 wound around the
outer periphery of the cylindrical portion 8, the wave receiver 4a side is in the arrow X direction
and the wave receiver 4b is in the arrow Y direction with the middle point 3a as a boundary. It is
wound. That is, the winding direction is reversed between the side of the wave receiver 4a and
the side of the wave receiver 4b.
[0012]
Next, the storage tray 7b is stacked on the storage tray 7a which has already received the wave
receiver 4a and is stored in the weight 6. Next, as shown in FIG. 4, the same winding operation is
performed in the wave receivers 4 c and 4 d to stack them on the storage tray 7 b and store them
in the weight 6. And as shown to Fig.5 (a), the weight 6 is accommodated in the exterior case 10
with the underwater electronic part 5, and the accommodation of the line array receiver 1 is

completed.
[0013]
When the line array receiver 1 of storage completion is started to be expanded in water, as
shown in FIG. 5 (b), the underwater electronic unit 5 is expanded and the receiver 4d of the
uppermost stage is an outer case together with the storage tray 7d. It is pulled out from 10 and
the weight 6, and further pulled out from the inside of the cylindrical portion 8 of the storage
plate 7d and expanded. The cable 3 between the wave receiver 4d and the wave receiver 4c
wound around the outer periphery of the cylindrical portion 8 of the storage plate 7d is a
connection portion of the wave receiver 4d and the wave receiver 4c at the boundary of the
storage plate 7d. 5c, and the storage tray 7d is separated from the cable 3 and descends as an
unnecessary item as shown in FIG. 5 (c). At this time, since the winding direction of the cable 3
which has been fed out is reversed with the intermediate point 3a as a boundary, the cables 3 are
stretched while canceling the twist generated in the cable 3.
[0014]
Next, the receivers 4c, 4b, 4a are sequentially expanded in the same manner, and as shown in
FIG. 5 (d), the weight 6 is pulled out of the outer case 10 to complete the expansion. And exterior
case 10 becomes unnecessary and descends.
[0015]
Thus, between the wave receiver 4a and the weight 6, between the wave receivers 4a and 4b, and
the wave receiver 4b on the projection 11 provided on the outer periphery of the cylindrical
portion 8 of the storage trays 7a, 7b, 7c, 7d. , 4c, or between the receivers 4c, 4d, and the cable 3
folded into two is wound around the outer periphery of the cylindrical portion 8 by hooking the
approximately half dividing point 3a of the cable 3 between the two. The winding direction of
each of the cables 3 folded back is reversed at the midpoint 3 a of the cable 3. This makes it
possible to easily and reliably perform the winding operation of the cable 3 with a simple
structure and in which no twisting occurs, thereby preventing a cost increase. Further, the cable
3 can be expanded without being damaged, and the highly reliable line array receiver 1 can be
stored without losing the original function of the marine sensor.
