Problems solved by technology

On the one hand, this manual cleaning operation method is inefficient, high in cost, and relatively dangerous; on the other hand, for offshore platforms with large operating water depths, due to the limitation of the diving depth of the human body, divers cannot dive to the seabed for cleaning operations, thus Facing the problem that such mooring anchor chains cannot be cleaned in service

Abstract

The invention relates to an automatic underwater anchor chain cleaning device and a cleaning method thereof. The automatic underwater anchor chain cleaning device comprise a mechanical body matched with an anchor chain, wherein the mechanical body is connected with a cavitation jet device through an umbilical cable; and the automatic underwater anchor chain cleaning device further comprises a control system electrically connected with the mechanical body and the cavitation jet device. The automatic underwater anchor chain cleaning device is compact and reasonable in structure and convenient tooperate, the structure of the mechanical body is ingeniously designed, thus the automatic cleaning work of the anchor chain is conveniently realized underwater, the working reliability is good, the working efficiency is high, manual operation of divers is replaced, and then the safety performance of underwater work is greatly improved.

Description

technical field [0001] The invention relates to the technical field of marine engineering equipment, in particular to an automatic cleaning device for underwater anchor chains and a cleaning method thereof. Background technique [0002] The mooring system is an important equipment to ensure the normal production operation of the offshore platform. It mainly has two structural forms: the mooring system and the dynamic positioning system. The mooring system has the characteristics of less investment, convenient use and maintenance, so it is the main positioning system used recently. The anchor chain is an important part of the mooring system. It connects the anchor with the offshore platform and transmits the anchor's holding force to the offshore platform. However, because the anchor chain is soaked in seawater all the year round, a thick scale layer will inevitably be formed on its surface. Composition, tight and firm. In general, the attachment of marine organisms will l...
