Long-term observing and biology trapping device for deep sea environment

Abstract

The invention discloses a long-term observing and biology trapping device for a deep sea environment.The device comprises a buoyancy device.The device is characterized in that a rack connected with the buoyancy device is included, the rack is provided with glass power supply bins which are internally provided with power supplies and low-power dissipation power supply managing circuits in a packaged mode, biology trappers, a deep sea image observing instrument, a deep sea environment parameter measuring instrument and an acoustic releaser, and the acoustic releaser is connected with a bearing block.The device is suitable for full deep sea environment observation and entrapment of large deep-sea near-bottom fishes with the high action capacity, supplies technical support to deep sea scientific research and has the advantages of being suitable for deep-sea long-term observation, increasing the trapping sampling success rate and avoiding the phenomenon that a carrying instrument is damaged due to the fact that the instant shock is too big when the device lands under the sea.

Description

technical field [0001] The invention belongs to the field of deep-sea long-term observation and detection and deep-sea biological sampling, and particularly relates to a long-term deep-sea environment observation and biological trap, which is suitable for full-deep-sea environment observation and trapping of deep-sea near-bottom fish with strong large-scale activities, and can be used for marine biological diversity Provide technical support in the fields of nature research, deep-sea biogeography research, deep-sea environmental protection and sustainable development and utilization of biological resources. Background technique [0002] For a long time, many people, including marine scientists, have regarded the deep sea below 1,000 meters as a relatively independent and stable ecosystem. However, recent studies have shown that the deep-sea ecosystem plays a very important role in the global carbon cycle and climate change, and the research on the deep-sea ecosystem has beco...

AI Technical Summary

Problems solved by technology

[0004] Self-returning deep-sea observation equipment is basically released in a free-fall manner. When the equipment hits the bottom, the impact force is relatively large, and it is easy to damage its own structure and the equipment it carries. If the equipment is damaged, long-term observation will lose its meaning. Therefore, this type of equipment must be equipped with a buffer mechanism. At present, there is no buffer mechanism for domestic drop-in instruments and equipment.

[0005] At present, the deep-sea observation equipment that operates independently has a limited number of batteries and low battery life, making it difficult to achieve long-term observation
