Technology background There are some foreign universities and research institutes that have installed, designed and manufactured similar in-situ deep-water exploration platforms out of research needs.
The platforms can be customized to a high degree, and observation items and sampling equipment can be replaced at any time to achieve different scientific research purposes.
By contrast, research and development technology of related equipment in China started relatively late.
At present, there have not been similar in-situ deep-sea detection platforms yet in China's marine research frontline, and detection and sampling methods are relatively single.
Sampling, measuring and geophysical exploration are all separated.
According to different investigating methods, scientific researches are done using different vessels, voyages, winches in different times and seasons, and even in different locations.
Later, data and samples are processed in the laboratory, which makes data interpretation and sample analysis more difficult.
Therefore, in-situ comprehensive detection and sampling is extremely urgent.
At present, several integrated scientific research vessels equipped with or about to be equipped with optical cables in China, such as “Da Yang 01”, “Ke Xue", “Hai Yang 06”, “Xiang Yang Hong 10”, "Xiang Yang Hong 01, “Xiang Yang Hong 03” and new scientific research vessels such as "Xue Long 02°, “Hai Yang” and “Shen Hai” ready to be put into scientific research missions after checking and acceptance, will carry underwater equipment based on optical cable communication.
These scientific research vessels are also main force of deep-sea resource detection and ocean-going basic scientific investigation, laying a solid foundation for deep-sea scientific investigation and national ocean strategy in the future.
Summary of the invention The present invention is designed to provide an integrated in-situ deep-sea detection and sampling platform.
A beneficial effect of the present invention is that it can realize accurate collection of target samples of deep seabed.
The samples and data obtained are not only characterized by in-situ collection, but also are highly consistent in time and space domains, providing very important evidence for the identification and analysis of key sea areas and rapidly changing seabed activities.
