Example Embodiment

[0023] The present invention will be described in detail below with reference to the drawings and embodiments.

[0024] The invention provides a modular embedded cylindrical conformal sound array for mines, see attached figure 1 And figure 2 , Including: transducer unit 2, watertight socket 3, watertight cable 4, sound-absorbing baffle 5 and wire 12;

[0025] Its peripheral equipment includes a cylindrical shell 1 and an instrument compartment shell 6 that are coaxially butted; the diameter of the cylindrical shell 1 of the mine is larger than the diameter of the instrument compartment shell 6;

[0026] The sound-absorbing baffle 5 is a deflector with an arc-shaped cross-section. The material is made of sound-absorbing rubber. The sound-absorbing baffle 5 has the effect of sound absorption and diversion, which can restrain underwater noise and avoid water The lower incident sound wave is reflected on the surface of the instrument compartment shell to produce a surround wave;

Abstract

The invention discloses a torpedo modular embedded type cylindrical conformal acoustic base array and belongs to the torpedo technical field. The torpedo modular embedded type cylindrical conformal acoustic base array includes transducer units, watertight sockets, watertight cables and wires; two or more transducer units are uniformly fixed at the periphery circumferential surface of an instrument cabin section shell along a circumferential direction; and the length direction of the transducer units is consistent with the axial direction of the instrument cabin section shell. One end of each transducer unit abuts against an end surface of a torpedo cylindrical shell, and the corresponding watertight socket is fixed to the other end of the transducer unit; one end of each watertight socket is connected with positive pole plate and negative pole plate of two piezoelectric ceramic discs through wires, and the other end of the watertight socket is connected with a socket in a torpedo instrument cabin through the watertight cable; and therefore, electric connection of the transducer units and instruments in the torpedo instrument cabin can be realized. According to the torpedo modular embedded type cylindrical conformal acoustic base array of the invention adopted, integral modular encapsulation and bunched installation are performed through the plurality of piezoelectric sensitive elements, and signals are transmitted through the watertight sockets, and therefore, the number of holes and the diameter of the holes in the shell can be decreased.

Description

technical field [0001] The invention belongs to the technical field of mines, and in particular relates to a modular embedded cylindrical conformal acoustic array for mines. Background technique [0002] In order to meet the detection function requirements of underwater targets, the detection system of sea mine weapons usually adopts the method of multiple acoustic transducers to form a sensor array. It can be seen from the basic principles of underwater acoustics that the more transducers that constitute the array array, the higher the gain of array signal processing, and the better the detection effect of underwater targets. The mechanical structure and installation method of the annular piezoelectric ceramic transducer used in the mine weapon in the past usually required corresponding mounting holes to be opened on the shell of the mine. The greater the number of openings, the more unfavorable the impact on the strength of the mine shell, and the higher the requirements ...
