Problems solved by technology

The details are as follows: (1) The abyss area is a deep sea of ​​6500-11000m, which is a completely unknown environment, and it is difficult to guarantee the safety of the divers and the stable operation of the instruments
(2) The environment of the ocean abyss is dark, low temperature, and high pressure, and it is difficult for optical and acoustic signals to propagate
(3) The traditional way to explore the ocean abyss is to take the manned submersible to take the researcher to dive into the water. The researcher needs to complete a large number of tasks within a limited time. The fault tolerance rate is low, and operation errors are prone to occur, which affects the success of the exploration task. Rate
(4) There is no public easy-to-operate and easy-to-implement method that allows people to safely explore the unknown ocean abyss

Abstract

The invention discloses a method for investigating deep rillouin by adopting an offshore mobile laboratory system, which greatly improves the operation efficiency and safety. Wherein the offshore mobile laboratory system comprises a mother ship with an analysis laboratory, an unmanned bathyscaph, a manned bathyscaph and a plurality of landers which can be connected with a sampling robot and are provided with acoustic positioning systems; the method specifically comprises the following steps that 1, the unmanned bathyscaph scans and measures a target sea area in a large range so as to screen out a target area; 2, the lander is arranged, and an underwater positioning system is established to serve as a guarantee for underwater positioning of the manned deep submergence vehicle and the unmanned deep submergence vehicle; 3, the unmanned bathyscaph and the manned bathyscaph are distributed, and underwater positioning communication and operation are conducted; 4, the unmanned deep submergence vehicle and the manned deep submergence vehicle float upwards; and 5, the unmanned bathyscaph and the manned bathyscaph are recycled, and the lander floats upwards.

Description

technical field [0001] The invention relates to an abyss survey operation method, in particular to a method for surveying an abyss by using a mobile laboratory system on the sea. Background technique [0002] Ocean abyss research can provide a deeper understanding of the origin of life on Earth, sense climate change, promote marine environmental protection, and improve earthquake prediction. However, due to the great technical difficulty of abyss equipment, there is currently a shortage in the world. The abyss area has become the weakest link in marine science because of the lack of survey equipment. [0003] Deep sea operations are different from land operations, and there are many technical difficulties in them. The details are as follows: (1) The abyss area is a deep sea of ​​6500-11000m, which is a completely unknown environment, and it is difficult to guarantee the safety of the divers and the stable operation of the instruments. (2) The environment of the ocean abys...
