Embodiment 1

[0023] The invention provides a wiring structure of a piezoelectric hydrophone array, the section of which is as follows figure 2 shown. The wiring structure of the piezoelectric hydrophone array includes a support block 21 and a cold pressure ring 22; the cold pressure ring 22 fixes the support block 21 and the hydrophone together in the piezoelectric hydrophone array On the flexible load-bearing structure 23. Further, the support block 21 has a wire groove 24 in the circumferential direction, such as image 3 shown. After welding the lead wires of the hydrophone and the preset wires in the piezoelectric hydrophone array, the solder joints and the preset wires of a certain length are embedded in the wire groove 24 along the circumferential direction according to the wire sequence. Furthermore, the material of the flexible load-bearing structure 23 is a polyurethane material with a characteristic impedance similar to that of water, and the polyurethane material has a certa...

Abstract

The invention discloses a wiring structure for a piezoelectric hydrophone array, and belongs to the technical field of hydrophone arrays. The wiring structure for the piezoelectric hydrophone array comprises support blocks and cold pressing rings, wherein the support blocks and a hydrophone are commonly fixed to a flexible force-bearing structure arranged in the piezoelectric hydrophone array through the cold pressing rings; and wire guiding grooves are formed in the support blocks in the circumferential direction. After a lead-out wire of the hydrophone and a pre-arranged lead wire arranged in the piezoelectric hydrophone array are welded, a welding spot and the pre-arranged lead wire having certain length are embedded into the wire guiding grooves according to the wire sequence in the circumferential direction, so that the survival reliability of the common piezoelectric hydrophone array is greatly improved, the assembling efficiency of the array is improved, identification error ratios of lead wires in assembling and maintenance processes are reduced, and a transmission signal-to-noise ratio of the array is effectively increased; and moreover, the wiring structure for the piezoelectric hydrophone array can be applied to the piezoelectric hydrophone array with a variety of lead wires.

Description

technical field [0001] The invention relates to the technical field of hydrophone arrays, in particular to a wiring structure of piezoelectric hydrophone arrays. Background technique [0002] Piezoelectric hydrophones are receiving transducers used to obtain sound pressure information in underwater sound fields, which use the piezoelectric effect of piezoelectric materials to convert sound pressure into voltage signal output. Connecting a certain number of hydrophones at a certain distance to form a hydrophone array can obtain higher signal gain. Oil-filled or rubber-filled arrays are common forms of hydrophone arrays. The flexible load-bearing structure is used to arrange the hydrophones at fixed intervals, and then add a number of support blocks to protect the hydrophones. The inner wire is connected with the lead wire of the hydrophone, and then penetrated into the sound-transmitting water-blocking outer casing, and finally the outer casing is filled with oil or glue to ...
