Example Embodiment

[0013] like figure 1 , figure 2 and image 3 As shown, the present invention consists of a hose winch (1), a combined hose (2), a submersible pump (3), a winch bracket (4), a winch drum (5), a motor (6), a reduction box (7), a control It is composed of a tank (8), a seawater output end (9), a hose guide device (10), a pump body guide frame (11), and a pile punching pipeline (12). Connect the submersible pump (3) to one end of the combined hose (2). The combined hose (2) is wound around the winch drum (5) on the hose winch (4), and the motor (6) is started through the control box (8). ) and the reduction box (7) to realize the simultaneous retraction and release of the submersible pump (3) and the combined hose (2). The seawater output end (9) is directly connected to the platform.

[0014] The pile punching pipeline (12) on the pile legs (13) is used as the guide rail of the submersible pump. The pump body guide frame (11) matched with the pile punching pipeline is arrang...

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...
