Problems solved by technology

However, the use of welding will bring the following disadvantages: the difference in longitudinal displacement of each pressure shell will inevitably cause bending deformation of the frame structure, increase the maximum principal stress, and easily cause fatigue damage; residual tensile stress is common in welded steel structures, increasing Possibility of fatigue damage; once visible fatigue cracks are generated, they will spread rapidly and cause damage to the connection part or frame structure; welding quality depends largel

Embodiment Construction

[0036] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0037] like Figure 1-Figure 8 As shown, the connection joint between the deep-sea platform pressure body and the frame of this embodiment includes a frame 5, and a plurality of pressure shells 18 are installed inside the frame 5, and each pressure shell 18 is connected to the frame 5 through displacement compensation. Joint 10, movable joint 17 and fixed joint 20 are connected.

[0038] The frame 5 is provided with a front connection frame 21, two middle connection frames 22 and a rear connection frame 23, one end of the fixed joint 20 is installed on one of the middle connection frames 22, and the displacement compensation joint 10 is installed on the front connection frame 21 at the most two ends And on the back connection frame 23, movable joint 17 is installed on another middle connection frame 22.

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...
