AI Technical Summary

Technical Problem

Existing technologies cannot accurately reflect the changes in the mechanical properties of buoyancy materials in deep-sea environments, cannot meet the balanced design requirements of submersibles operating in deep sea, and lack the technical basis for automatic control and safety early warning.

Method used

A testing device for the mechanical properties of buoyancy materials in a deep-sea environment was designed, including a split high-pressure tank, a ball cage device, a grating assembly, and a photosensitive sensor. By simulating pressure, temperature, and density changes in a deep-sea environment, the mechanical properties of buoyancy materials can be measured in real time.

Benefits of technology

It enables the measurement of the actual mechanical properties of buoyancy materials in the deep-sea environment, provides a basis for technical evaluation, improves the balance design and safety of submersibles, and is applicable to the automatic control of submersibles.
