AI Technical Summary
There are safety risks when submersibles operate in polar ice areas, such as collisions with the seabed or ice layer due to excessively rapid descent, collisions with the mother ship due to excessively rapid ascent, and loss of positioning signal due to obstruction.
The release mechanism, driven by differentiated electromagnets, includes a de-energized electromagnet and an excitation electromagnet, which are used to release the jettisonable buoyancy components, emergency position beacons, and ballast, respectively. The mechanism is combined and controlled according to the operation stage and abnormal conditions to ensure optimized buoyancy and safety redundancy.
It has enabled the safe navigation and reliable recovery of unmanned, untethered submersibles in polar ice areas. Through buoyancy optimization and anomaly response, it has ensured the safety and control precision of the entire operation process.
