BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows an embodiment of the present invention,
FIG. 1 is a general perspective view, and FIG. 2 is a perspective view with a part cut away. 2 end
plate 4 tube 5 pre-amplifier.
DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of a
submerged acoustic receiver. In the case of underwater acoustics, the underwater acoustics are
converted to a papermaking signal by a delivery device and then analyzed. The electrical signal is
weak and the transmission distance to the analyzer is large. In many cases, 1S is required to have
a preamp. On the other hand, when suspending the underwater acoustic receiver and floating
amplifier in water, it is necessary for the company to have a shape and structure that is
convenient for operation and not affected by water pressure, and a large number of delivery
devices. It is important that the shape of the wave receiver is simple, especially when the array is
connected in the shape of a bead to make the array 3--, the state (E)-1 ÷ to S ÷-. Therefore, the
object of the present invention is to provide an underwater acoustic wave receiver that satisfies
the above requirements. An end plate made of aluminum is fixed to the cylindrical end face of the
thin-walled cylindrical piezoelectric conversion element portion l, and an aluminum pipe rod is
inserted and fixed to the center hole 3 of the thin cylindrical cylindrical piezoelectric conversion
element portion l. The pre-amplifier S (the figure shows the one housed in a thick cylindrical
case) is supported so as not to contact the inner surface of the piezoelectric conversion element
portion l so that the airtight chamber 6 is interposed therebetween. Ru. The connection wire of
the preamplifier 3 is pulled out through the end plate, and the gauze is connected to the
receiving device in the form of beads and suspended in water or towed horizontally. The airtight
chamber 6 has an inner diameter suitable for bundling and inserting the strength members for
connection and the wires of the delivery device, and the airtight chamber 6 functions to faithfully
vibrate the piezoelectric conversion element portion I according to the change in sound pressure
Do not borrow a year) Therefore, according to the present invention, the piezoelectric conversion
element portion l has a large delivery surface with a cylindrical body, and at the same time,
stores the preamplifier S in a space in the cylinder to make the entire structure small and
lightweight for sensitivity. There is a feature that the shape is simple, the paper is treated and
treated, and the influence of water pressure is not received. In addition, since the strength
members and the electric wires are inserted into the gutter, it is possible that the electric wires
run on the wave receiving surface and can form an array that is orderly and easy to handle.
