Large-angle compensation heavy-load suspension spherical joint suitable for deep-sea mining operation

Abstract

The large-angle compensation heavy-load suspension spherical joint comprises an upper shell and a spherical lower joint which are coaxially arranged together in a sleeved mode, the upper shell is connected to a mining operation platform in a suspension mode, and the spherical lower joint is connected with an underwater hard pipe. And the underwater system and the mining operation platform are connected into a whole. As a flexible connecting device, the large-angle compensation heavy-load suspension spherical joint can compensate the angle deviation generated by underwater equipment in ocean current during mining operation or danger avoiding, relieve the bending moment of a mining operation platform and the underwater equipment, prevent an underwater hard pipe from being bent and damaged, and guarantee the safety of the mining operation equipment.

Description

technical field [0001] The invention relates to the technical field of deep-sea mining, in particular to a large-angle compensation heavy-load suspension ball joint suitable for deep-sea mining operations. Background technique [0002] Deep sea mining engineering is a relatively complex system engineering, which is mainly divided into surface system and underwater system. Surface systems mainly include mining operation platforms and deployment and recovery systems; underwater systems are mainly underwater hard pipes, underwater relay stations, multi-stage lift pumps, hoses and mining vehicles. During the actual mining operation, the underwater system is suspended above the surface system, and under the influence of factors such as ocean waves and ocean currents, it may be displaced, resulting in failure and damage of the hard pipe, which will adversely affect the entire mining project. [0003] Therefore, the connection suspension equipment between the surface system and th...

Problems solved by technology

However, at present, there are few domestic research contents on this aspect, and the problems existing in the above mining operations cannot be effectively solved. Therefore, it is necessary to design a connection device for the surface system and the underwater system, so that it can adapt to deep sea mining The heavy-duty operation requirements of the system meet the large-angle offset compensation of the deep-sea mining surface system and underwater system under complex sea conditions, so as to ensure the safe and reliable operation of the mining system and improve the reliability and safety of the entire deep-sea mining engineering operation
