DESCRIPTION JPH052499
[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an
expanded structure of a receiver for underwater exploration buoy.
[0002]
2. Description of the Related Art As shown in FIG. 3, in the expansion structure of a conventional
underwater survey buoy receiver, as shown in FIG. When the vessels 1 to 4 are stacked and
stored in the outer cylinder of the underwater exploration buoy (not shown) and the underwater
exploration buoy is activated and the lower plate (not shown) supporting the receivers 1 to 4 is
removed It was a structure expanded by its own weight. The cords 20 connecting the receivers 1
to 4 are housed with gaps provided between the respective receivers when the receivers 1 to 4
are stacked and stored.
[0003]
[0003] In the conventional expansion structure of the underwater survey buoy receiver, the
receiver and the receiver are connected by a flexible nylon string or the like. When using an
underwater exploration buoy in the ocean, each receiver moves or rotates independently due to
tidal current, etc., so the positional relationship between the receivers and the azimuth angle
change, resulting in a decrease in exploration performance. was there.

SUMMARY OF THE INVENTION The expanded structure of the submersible buoy receiver
according to the present invention comprises at least two supporting structures each consisting
of a plurality of coaxially arranged mutually sliding cylinders. Is a structure that connects two
adjacent receivers to each other.
[0005]
Next, the present invention will be described with reference to the drawings.
[0006]
FIG. 1 is a view showing an embodiment of the present invention.
[0007]
In the support structures 5 to 7 in FIG. 1, as shown in FIG. 2, the pipe 8 slides in the pipe 9, and
the stopper 12 expands and contracts until it strikes the stoppers 13 and 14.
In the present embodiment, an example of a two-tiered support structure is shown, but a threetiered, four-tiered support structure may be used in order to further extend the stretching length.
[0008]
The expanded structure of this embodiment is a structure in which two adjacent receivers are
connected by a pair of support structures, and when stored, the support structures 5 to 7 are as
shown in FIG. 1 (B). As shown in FIG. 1C, the support structures 5 to 7 are dimensioned so that
the expansion dimensions between the respective receivers become equal when they are
accommodated and expanded in the entire length of the receivers.
[0009]
A support structure 5 is used to connect the receivers 1 and 2, and the receiver 1 is provided
with a hole into which the holder 11 (see FIG. 2) at the upper end of the support structure 5 and
the pipe 8 enter. The receiver 2 is provided with a hole through which the pipe 9 of the support

structure 5 passes.
Also, the receivers 3, 4 are provided with holes or notches larger than the outer diameter of the
holder 10 so that the holder 10 at the lower end of the support structure 5 can pass when
expanded.
[0010]
Although a support structure 6 is used to connect the receivers 2 and 3, the receiver 2 is
provided with a hole into which the holder 11 at the upper end of the support structure 6 and
the pipe 8 are inserted. The hole has a hole for the pipe 9 to enter.
Also, the receivers 1, 4 are provided with holes or notches through which the holders 10, 11 of
the support structure 6 pass.
The support structure 7 is used to connect the receivers 3 and 4, but each receiver has the
necessary holes as described above.
[0011]
When the underwater exploration buoy is activated and the respective receivers and the plates
(not shown) supporting the lower portions of the support structures are detached, the receivers 2
to 4 fall under their own weight, as shown in FIG. Expand as in).
In addition, even if the number of receivers increases, it is the structure which can respond by
considering each part dimension of the support structure, and the number of expansion steps.
[0012]
As described above, according to the present invention, each receiver has high rigidity by using
the support structure consisting of a plurality of cylinders sliding with each other for the
expansion structure of the receiver. Because the pipes are firmly connected, each wave receiver
does not move or rotate independently even if there is a flow, etc., and the positional relationship

and azimuth angle between the wave receivers are constant, so the detection performance is
improved. Have the effect of
