Problems solved by technology
This method requires separate operation of deck cranes or other power lifting equipment, and some platforms are restricted by layout
When the deck crane cannot realize the lifting operation of the submersible pump smoothly and conveniently, it is necessary to add additional lifting equipment for the submersible pump, such as a winch, which will increase the purchase and maintenance costs of the platform, increase the weight of the platform, and reduce the available space of the platform

The invention provides a self-lifting platform and a submerged pump system thereof and a submerged pump lifting method. The submerged pump system of the self-lifting platform comprises a submerged pump tower and a base. The base is arranged corresponding to the submerged pump tower. The base comprises a base body and a bearing plate, the base body is fixedly arranged on the upper surface of a pileshoe of the self-lifting platform, and the bearing plate is arranged at the end, away from the pile shoe, of the base body. The lower end of the submerged pump tower can be supported on the bearing plate so that the submerged pump tower can rise and descend along with the base. Through the self-lifting platform and the submerged pump system thereof and the submerged pump lifting method, the situation can be avoided that a deck crane or other power lifting devices are used for lifting the submerged pump independently, the platform purchase and maintenance cost is reduced, the platform weight is reduced, and the platform available space is increased.
Description
technical field [0001] The invention relates to the field of self-elevating platforms, in particular to a lifting system and a lifting method for a self-elevating platform and a submersible pump thereof. Background technique [0002] The submersible pump is the seawater supply equipment for the self-elevating platform, and its main functions are as follows: injecting seawater into the ballast tank of the self-elevating platform to meet the ballast requirements; supplying pre-ballasted seawater for the platform without a separate pre-ballast pump; Platform cooling system, seawater fire-fighting system, nitrogen production system and other systems that require seawater to provide seawater sources for the normal operation of the platform, therefore, submersible pumps play an extremely important role relative to the entire platform. [0003] Usually the submersible pump is placed on the platform. When the submersible pump needs to be used, the submersible pump needs to be lowere...
