Embodiment Construction

[0046] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0047] The seawater lifting device arranged in the legs of the present embodiment, such as figure 2 As shown, it includes a seawater lift pump 1 and a water delivery pipe 2. The seawater lift pump 1 is installed at the bottom of the water delivery pipe 2 and communicated with the water delivery pipe 2. The water delivery pipe 2 is vertically installed in the leg 8 of the offshore platform 9 , the legs 8 are truss legs;

[0048] like image 3 As shown, the top of the water delivery pipe 2 is closed, and a plurality of outlet nozzles 21 are evenly spaced on one side of the water delivery pipe 2;

[0049] like Figure 4 , Figure 5 As shown, it also includes a conduit 3, a conduit pulley mechanism 23, a traction mechanism 5 and connecting lugs 22, the traction mechanism 5 is installed on the offsh...

Abstract

The invention discloses a seawater lifting device arranged in a spud leg. The seawater lifting device comprises a seawater lifting pump and a water delivery pipe. The seawater lifting pump is installed at the bottom end of the water delivery pipe and communicates with the water delivery pipe, the water delivery pipe is perpendicularly installed in the spud leg of an ocean platform, two guiding pipes are close to the two sides of the water delivery pipe correspondingly and arranged in a truss of the spud leg, and the two ends of each guiding pipe are fixedly installed on the spud leg. A bulky lifting frame and a complex lifting driving mechanism are not needed, seawater extraction can further be achieved, the length of the water delivery pipe does not need to be larger than the height difference between the ocean platform and the sea level, the water delivery pipe is dropped into sea by adjusting the down-pass length of a tow rope, material consumption is reduced, and the production cost and the production difficulty are reduced; lifting can be controlled only through a rope collecting machine, operation is simple, energy consumption is low, and the using cost is reduced; and the seawater lifting device is arranged in the spud leg, a lifting channel does not need to be additionally arranged on the ocean platform, and less space is occupied.

Description

technical field [0001] The invention relates to the field of offshore platforms, in particular to a seawater lifting device arranged in pile legs. Background technique [0002] An ocean platform is a common ocean engineering equipment, which mainly includes a platform body and legs. When the offshore platform is in normal operation, the domestic water and production water on the offshore platform need to rely on the seawater lifting device to transport from the sea surface. The existing seawater lifting device includes a tower, a lifting mechanism and a seawater lifting pump. The tower is movably inserted on the main body of the platform, and the lifting mechanism is installed on the main body of the platform to drive the lifting of the tower. The seawater lifting pump is installed on the tower. the bottom of the shelf. When the seawater lifting device is required to transport seawater, the lifting mechanism drives the tower down until the seawater lifting pump contacts th...
