Problems solved by technology

[0003] The disadvantage of this method is: there are many supporting equipment, and it is necessary to configure the cable retractable winch, the lifting pipeline for adapting to different air gap heights and the manifold on the platform, and use the hose to connect the submersible pump, the lifting pipe and the platform pipeline; Complicated, the pneumatic winch and cable winch must be operated at the same time when the platform is raised and lowered to retract the submersible pump and cables
Requires a bulky hose connection for every use

Embodiment Construction

[0013] Such as figure 1 , figure 2 with image 3 As shown, the present invention consists of a hose winch (1), combined hose (2), submersible pump (3), winch support (4), winch drum (5), motor (6), reduction box (7), control Box (8), seawater output port (9), hose guide device (10), pump body guide frame (11), pile flushing pipeline (12). Connect the submersible pump (3) to one end of the combination hose (2), which is wound on the winch drum (5) on the hose winch (4), start the motor (6) through the control box (8) ), the reduction box (7) realizes the synchronous retraction and retraction of the submersible pump (3) and the combined hose (2). The seawater output terminal (9) is directly connected with the platform.

[0014] The pile flushing pipeline (12) on the pile leg (13) is used as the guide track of the submersible pump, and the submersible pump is equipped with a pump body guide frame (11) matched with the pile flushing pipeline, and a hose winch (1) is installed...

Abstract

The invention relates to an ocean platform submersible pump winding and unwinding method which comprises a hose winch (1), a combined hose (2), a submersible pump (3), a winch bracket (4), a winch barrel (5), a motor (6), a reduction gearbox (7), a control cabinet (8), a seawater output end (9), a hose guiding device (10), pump body guiding frames (11) and pile washing-out pipelines (12). The method is characterized in that the submersible pump (3) is connected to one end of the combined hose (2); the combined hose (2) is wound onto the winch barrel (5) on the hose winch (4); and the motor (6) and the reduction gearbox (7) are started by the control cabinet (8) to realize synchronous winding and unwinding of the submersible pump (8) and the combined hose (2). The method is simple, safe and reliable, is easy to operate, can meet the using requirement of a platform, has high adaptive capacity to environment, avoids being influenced by platform lifting, alleviates the operation intensity of submersible pump winding and unwinding, saves operation time and manpower and has high economic efficiency.

Description

technical field [0001] The patent of the present invention relates to a retractable method of a submersible pump on an offshore platform. It is installed on an offshore platform and is mainly used for lowering the submersible pump below the water surface when the platform is raised above the sea surface, so as to provide ballast for the platform and cool the seawater. When the platform is in a floating condition, the submersible pump needs to be lifted and recovered to the platform, as well as areas with similar operating requirements. Background technique [0002] The existing submersible pump retraction method of the offshore platform is generally the pneumatic winch type: a fixed pulley is set on the top of the pile leg, and the retraction of the submersible pump is realized through the pneumatic winch. [0003] The disadvantage of this method is: there are many supporting equipment, and it is necessary to configure the cable retractable winch, the lifting pipeline for ad...
