Problems solved by technology

When developing a vector hydrophone with such a structure, it is usually irreparable when there is a problem with the measurement channel, that is, the internally damaged vibration sensor cannot be replaced
The irreparability of the vector hydrophone with this structure greatly increases the development cost of the vector hydrophone

Embodiment Construction

[0021] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0022] Firstly, a hollow spherical shell 4 with seven round holes will be made. The spherical shell 4 is made of rigid low-density composite material, and the six round holes are divided according to the Cartesian space coordinates, which are used to inlay six vibrating sensor 1. Then use waterproof glue to fix the watertight output cable head 5 in the remaining round hole, divide the core wires 3 of the output cable into six groups, and take them out from the six round holes respectively. After connecting the output wires of the six vibration sensors 1 with the mounting threaded holes 2 that have been watertight to the core wires 3 of the output cables taken out from the six round holes, respectively fix the six vibration sensors 1 with waterproof glue In the circular hole, the connected core wire 3 is also sent into the hollow spherical shell 4 full of air 6 at...

Abstract

The invention provides a hollow-structured three-dimensional vector hydrophone with neutral buoyancy in water. The three-dimensional vector hydrophone comprises a shell and six vibrating sensors, wherein the shell is shaped into a sphere, the sphere is provided with six vibrating sensor mounting holes and a cable output hole, the six vibrating sensor mounting holes are uniformly distributed on the surface of the sphere according to Cartesian coordinates, a vibrating sensor is inlaid in each vibrating-sensor mounting hole, the connecting cable of each vibrating sensor is drawn out from the cable output hole, and each vibrating sensor is provided with a mounting threaded hole for suspension. The hollow-structured three-dimensional vector hydrophone provided by the invention can be widely used in various underwater sound fields such as the measurement and target positioning of sonobuoys and low-noise moving-objects, and the like. The hollow-structured three-dimensional vector hydrophone provided by the invention has the advantages of small volume, and capability of facilitating the replacement of sensors and saving development cost, and the like.

Description

technical field [0001] The invention relates to a vector hydrophone, in particular to a three-dimensional vector hydrophone with a hollow structure and neutral buoyancy in water. Background technique [0002] The vector hydrophone is a vibration signal that can be time-synchronized and space-coordinated to measure a certain particle in the underwater sound field. Generally, the vibration sensor is used as the unit to pick up the vibration. Therefore, the vibration sensor can choose the acceleration sensor and the speed sensor. and displacement sensors. When designing and manufacturing vector hydrophones, the vibration sensor is usually rigidly connected into one body according to the three-dimensional coordinates of the space, then put it into the potting mold, potting with waterproof material, and finally take off the mold to get the production Nice vector hydrophone. The curing of the potting material is generally carried out at high temperature, which sometimes destroys...
