Problems solved by technology
The existing seawater lifting pump towers have the following disadvantages: on the one hand, the above-mentioned methods are all of the overall lifting type, and the pump tower is an overall towering structure with a height usually greater than 20 meters. When it is raised, it occupies the space above the deck and affects other operations; On the one hand, due to the lifting of the pump tower, multiple water outlets and valves need to be installed in the height direction, and the water outlets need to be replaced with the lifting of the pump tower; on the other hand, only two submersible pumps can be installed in each pump tower It cannot meet the water demand of the whole ship. Therefore, the whole ship needs to be equipped with multiple sets of seawater lifting pump towers; on the other hand, the equipment cost of rack and pinion and hydraulic pin lifting devices is high, and the requirements for processing and assembly are relatively strict

The invention relates to the technical field of shipbuilding and oceanography engineering equipment and provides a seawater lift pump tower and an offshore platform. The seawater lift pump tower comprises a fixing tower body, multiple retractable water lifting pipes, multiple water pumps and a driving assembly; the fixing tower body is provided with the water lifting pipes and fixing parts for connecting and fixing the water lifting pipes; each retractable water lifting pipe comprises two or more sleeving pipes, and the sleeving pipes are mutually in movable sleeving connection and are retractably communicated between the water lifting pipes and the water pumps; the water pumps are relatively away from or close to the fixing tower body, and the portions, away from the fixing tower body, ofthe water pumps enter water; the driving assembly drives the water pumps to be relatively away from or close to the fixing tower body, and accordingly the water pumps are switched to a water inlet position or a water outlet position. The seawater lift pump tower has the advantage of being easy and convenient to operate.
Description
technical field [0001] The invention relates to the technical field of ships and ocean engineering equipment, in particular to a seawater lifting pump tower and an offshore platform. Background technique [0002] When the self-elevating platform is in operation, the hull of the platform needs to be lifted to leave the sea level, and there is a certain air gap between the hull of the platform and the sea level. The function of the seawater lifting pump tower is to place the submersible pump below the sea level when the hull of the platform is suspended above the sea level, so that the submersible pump can work normally and pump out seawater, which is used for fire fighting, ballasting, production and equipment cooling of the self-elevating platform , life, etc. provide seawater. [0003] At present, the seawater lifting pump tower is mainly divided into crane lifting type, hydraulic bolt lifting type and pinion and rack lifting type according to the lifting method. The exis...
