Embodiment Construction

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

[0024] The present invention provides a modular embedded cylindrical conformal acoustic array for mines, see attached figure 1 And attached 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 mine cylindrical shell 1 and an instrument compartment shell 6 coaxially butted; the diameter of the mine cylindrical shell 1 is greater than the diameter of the instrument compartment shell 6;

[0026] The sound-absorbing baffle 5 is a deflector with an arc-shaped cross section, and the material is made of sound-absorbing rubber. The sound-absorbing baffle 5 has the effect of sound absorption and flow diversion, and suppresses the noise of the underwater flow, while avoiding water leakage. The downward incident sound wave is reflected on the shell surfa...

Abstract

The invention discloses a modular embedded cylindrical conformal acoustic array for a mine, which belongs to the technical field of mines, and comprises: a transducer unit, a watertight socket, a watertight cable and a wire; more than two transducer units are uniformly fixed along the circumferential direction On the outer peripheral surface of the instrument compartment shell, and the length direction of the transducer unit is consistent with the axial direction of the instrument compartment shell, one end of the transducer unit conflicts with the end face of the mine cylindrical shell, and the other end is fixed with a Watertight socket, one end of the watertight socket is respectively connected to the positive and negative plates of the two piezoelectric ceramic discs through wires, and the other end is connected to the socket in the mine instrument cabin through a watertight cable to realize the transducer unit and mine instrument The electrical connection of instruments in the cabin; the invention reduces the number and aperture of openings on the housing by adopting a plurality of piezoelectric sensitive elements as a whole modular potting, cluster installation, and transmitting signals through watertight sockets.

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 ...
