Multi-stage parallel dumping device and deep-sea lander

Abstract

The invention discloses a multi-stage parallel load throwing device, which includes a mounting plate; a wire-driven load throwing assembly includes a pre-tensioned steel wire, a first release mechanism and a first release lever, and the first release lever has a first lock that can be opened and closed Buckle, after the pre-tensioned steel wire is released, the first lock can be opened through the first release mechanism; the electromagnetic drive throwing assembly includes an electromagnetic drive part, a second release mechanism and a second release lever, and the second release lever has an openable The second lock; the electromagnetic drive part can open the second lock through the second release mechanism; the two ends of the release chain are respectively connected with the first lock and the second lock, after the first lock or the second lock is opened , the release chain disengages from the first lock or the second lock. The above-mentioned load dumping device, the wire-driven load dumping assembly and the electromagnetic drive dumping assembly are two independent release systems, which are respectively connected to the two ends of the release chain, and the load dumping release can be completed by releasing one end, which improves the safety and reliability of the system.

Description

technical field [0001] The invention relates to a load dumping device, in particular to a multi-stage parallel load dumping device and a deep-sea lander. Background technique [0002] In recent years, with the implementation of the national marine strategy, the research on the ocean, especially the deep sea, has continued to heat up, and the methods of research, observation and sampling have become increasingly diversified. According to the scientific goal of deep-sea submarine observation, various observation instruments and equipment are fixed on the frame and placed on the seabed for long-term and automatic in-situ observation, forming a deep-sea lander. When the deep-sea lander frame completes the observation task, it needs to discard the heavy block, and use the buoyancy material to lift the device from the seabed to the sea surface for recovery. In the prior art, the unloading of heavy blocks can be achieved through acoustic releasers, combustion rings, corrosion link...

AI Technical Summary

Problems solved by technology

In the prior art, the unloading of heavy blocks can be achieved through acoustic releasers, combustion rings, corrosion links or explosive fractures, etc. However, when an unexpected situation occurs, the above various dumping methods may fail. failure, will cause the load dump to fail to complete
