Problems solved by technology

[0002] When the offshore platform is in normal operation, the main body of the platform is mostly lifted above the sea surface. At this time, the seawater used by the platform for life, production, ballast, fire protection, power system cooling, etc. is provided through a dedicated set of seawater supply system. When the sea surface is raised to the platform, the seawater supply system usually includes a seawater lifting tower, which is an important part of the offshore operation platform. Due to the complicated situation of seawater, the driving device of the existing seawater lifting tower is often prone to failure. When the driving device fails , the seawater lifting tower cannot be raised and lowered normally, resulting in the failure of the seawater lifting operation

Embodiment Construction

[0047] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0048] Such as figure 1 As shown, a seawater lifting system includes a tower 1, a lifting device 2, a pumping device 3 and a surrounding well 4, and the tower 1 includes a main pipe 11, a horizontal pipe 12 and an inclined pipe 13, and the horizontal pipe 12 is welded Between the adjacent main pipes 11, the inclined tubes 13 are welded between the adjacent horizontal tubes 12, so that the tower 1 forms a triangular truss structure;

[0049] The lifting device 2 has two sets, and the lifting device 2 includes two sets of lifting units 21, and the two sets of the lifting units 21 cooperate with the two main pipes 11 to make the tower 1 lift up and down in the surrounding well among 4;

[0050] The water pumping device 3 includes a water diversion pipe 31 and a submersible pump 32 , both of which are...

Abstract

A seawater hoisting system comprises a tower frame, lifting devices, a water pumping device and a surrounding well. The tower frame comprises main pipes, transverse pipes and inclined pipes. Each transverse pipe is welded between the corresponding adjacent main pipes, each inclined pipe is welded between the corresponding adjacent transverse pipes, and therefore the tower frame can form a triangular truss structure. The number of the lifting devices is two. Each lifting device comprises two lifting units, and through the cooperation of every two lifting units and the two corresponding main pipes, the tower frame can rise and fall in the surrounding well. The water pumping device comprises water diversion pipes and submerged pumps. The water diversion pipes and the submerged pumps are all installed in the main pipes. The submerged pumps are installed at the bottom ends of the water diversion pipes. According to the above content, the four lifting units work together, it is ensured that seawater hoisting can be continuously conducted, and the reliability of the seawater hoisting system is improved.

technical field [0001] The invention relates to the technical field of marine engineering, in particular to a seawater lifting system. Background technique [0002] When the offshore platform is in normal operation, the main body of the platform is mostly lifted above the sea surface. At this time, the seawater used by the platform for life, production, ballast, fire protection, power system cooling, etc. is provided through a dedicated set of seawater supply system. When the sea surface is raised to the platform, the seawater supply system usually includes a seawater lifting tower, which is an important part of the offshore operation platform. Due to the complicated situation of seawater, the driving device of the existing seawater lifting tower is often prone to failure. When the driving device fails , The seawater lifting tower cannot be lifted normally, resulting in the failure of the seawater lifting operation.
