Description

Technical Field

[0002] The average depth of the global ocean is 3,800 meters, with nearly 90% of the area exceeding 1,000 meters and nearly 30% exceeding 3,000 meters. The deep sea is rich in oil, gas, minerals, biology, chemistry and space resources. It is a vast area on the earth that has not been fully developed and utilized by humans, and has unlimited development potential. Exploring the deep sea is an important prerequisite for realizing the development of deep sea resources. As a deep sea exploration equipment, the deep sea towing system has become one of the important platforms for deep sea exploration and research due to its rich equipment and high cost performance.

[0003] As the carrier and integrated platform of deep-sea exploration equipment, the towed body is an important component of the deep-sea towing system. The towed body needs to have sufficient structural strength, good hydrodynamic performance, and stability and safety of the towed body movement to adapt to the unique physical environment of the deep sea.

[0004] Existing deep-sea towing devices pay particular attention to their structural strength design, hydrodynamic performance, and towed body movement stability. The relevant design and manufacturing technologies are relatively mature. However, with the continuous deepening of deep-sea exploration and research, the application scenarios of deep-sea towing systems have become more diverse, and the requirements for the flexible carrying capacity of the towed body have become higher and higher. Based on the limitations of the towed body's own weight and loading and unloading transportation, how to arrange more types of detection equipment in a limited space and reserve sufficient expansion space; how to better adapt to a series of problems such as changes in the towed body's weight and buoyancy caused by flexible carrying, has become the key to the design of the towed body.
