Abstract

The invention relates to a connecting joint for a pressure-resisting body and a framework of a deep-sea platform. The connecting joint comprises a framework, wherein a plurality of pressure-resistingshells are mounted inside the framework; and each pressure-resisting shell and the framework are connected through a displacement compensating joint, a movable joint and a fixed joint. The connectingjoint is compact and reasonable in structure, is convenient to operate, can realize function conversion between the movable joint and the fixed joint through the displacement compensating joint, can realize longitudinal free movement, in a diving process, of a pressure-resisting body, and also can bear longitudinal impact load with the fixed joint after diving to working depth.

Description

technical field

[0001] The invention relates to the technical field of deep-sea platform auxiliary equipment, in particular to a connection joint between a pressure-resistant body and a frame of a deep-sea platform. Background technique

[0002] The environment of the underwater world is harsh, and it is necessary to overcome the huge seawater pressure. To exploit marine resources, especially the deep sea development, it needs to rely on deep sea diving equipment to complete. At present, all major countries in the world have vigorously developed deep-sea manned platforms, and deep-sea manned platforms are gradually developing in the direction of large-scale and multi-functional. The new deep-sea manned platform should have the characteristics of large payload, long residence time on the seabed, and the ability to perform multi-functional operations. The above characteristics make the multi-body pressure-resistant structure a trend. Such as: the offshore multi-purpose submar...
