12.5Mpa pressure resistant array and production method thereof

Abstract

The invention discloses a 12.5Mpa pressure resistant array and a production method thereof. The 12.5Mpa pressure resistant array comprises transducers, an array frame and a back cover plate. The transducers are sealed individually and supported independently and respectively arranged on the upper end face of the array frame, gridded wiring channels are arranged on the lower end face of the array frame, and surround to form square bosses having supporting effects, and the array frame directly contacts with the back cover plate. The 12.5Mpa pressure resistant array has the advantages that the transducers are supported independently and sealed individually, the gridded wiring channels are arranged on one side of the array frame, the square bosses in great quantity formed after grooving have supporting effects, and directly contact with the back cover plate, so that the array is guaranteed against deforming even in seawater 1000m in depth. By the spatial optimized method, problems about wiring are solved while weight of the array is lowered greatly; the inside of the array cannot be affected even when in water leakage caused by damage of cables in deep sea; and watertight safety coefficient is increased greatly by multiple protections, so that the array can run in deep sea reliably and stably for a long time.

Description

technical field [0001] The present invention relates to a matrix, more specifically, it relates to a matrix with a pressure resistance of 12.5 MPa and a preparation method thereof. Background technique [0002] Ocean internal wave monitoring technology is an important part of ocean dynamic environment research. How to continuously monitor ocean internal waves at fixed points for a long time is the key to ocean internal wave research. At present, the non-acoustic means of monitoring ocean internal waves in the world mainly include the following categories: mooring systems Instrument array observation, navigating and towing instrument observation, vertically lowering instrument observation, neutral float observation and satellite remote sensing observation, etc. [0003] At present, there are two main methods for marine scientists at home and abroad to use acoustic methods to monitor internal waves. One is to use existing ADCP and other equipment to obtain internal wave inform...

AI Technical Summary

Problems solved by technology

[0004] As a device for obtaining underwater information, the quality of the underwater transducer array is directly related to the overall performance of the ocean monitoring system. The main problem that the deepwater array needs to solve is pressure resistance and energy conversion under high static pressure. For transducers or arrays working in deep sea, pressure compensation or overflow is generally adopted, but oil-filled or liquid-filled methods are less reliable. If a failure occurs, it is difficult to repair and often Oil or fluid leaks, etc.
