Abstract
The invention discloses an offshore platform pile leg protection device, and belongs to the field of offshore equipment. The offshore platform pile leg protection device comprises an offshore platform body, a pile leg, a floating body, a spiral dirt scraping strip, a fixed ring and a diversion piece, wherein the pile leg is arranged below the offshore platform body; the floating body is sleeved on the pile leg; the spiral dirt scraping strip is arranged below the floating body; the fixed ring is arranged below the spiral dirt scraping strip and is sleeved on the pile leg. According to the offshore platform pile leg protection device, the spiral dirt scraping strip is wound on the pile leg; one end of the spiral dirt scraping strip is fixed to the floating body; the floating body is sleeved on the pile leg; the fluctuations of waves drive the floating body to perform vertical movement or rotary motion so as to drive the spiral dirt scraping strip attached to the pile leg to move; therefore, sea creatures attached to the pile leg are removed. The spiral dirt scraping strip of the pile leg can remove dirt, and can also prevent the pile leg from being damaged by the vortex vibration of the pile leg caused by ocean current. The pile leg protection device is simple in structure, unique in shape, and meanwhile, is easy and convenient to use.
Description
Technical field
The present invention relates to ocean platform spud leg protective device, belong to oceanographic equipment field.
Background technology
Ocean platform, provides and produces and the structure of living facilities for carrying out the activities such as drilling well, oil recovery, transporting something containerized, observation, navigation, construction at sea.Its architectural characteristic and duty can be divided into fixed, movable and semi-fixed type three major types.The bottom of fixed platform by stake, expand footing or other structure and directly support and be bonded to seabed, be divided into two kinds of pile foundation type and gravity by support situation.Movable platform floats in water or is supported in seabed, can move to another well location from a well location, can be divided into end formula and floating type two classes by support situation.Studying in recent years novel semi-fixed type ocean platform, it can be fixed in deep water, has again high movable, and tension leg type platform belongs to this type of.At present all be provided with spud leg at most of platforms of use; the whether firm direct relation of ocean platform spud leg the safety of platform; but the residing environment of spud leg is severe; not only be subject to washing away of wave and impact the attached corrosion that is also subject to marine growth; therefore not adding protection and can have a strong impact on its life-span, is a urgent problem at present.
Summary of the invention
The object of this invention is to provide ocean platform spud leg protective device.
The problem to be solved in the present invention is that ocean platform spud leg is easily subject to that washing away of wave impacts and the deficiency of the attached corrosion of marine growth.
Ocean platform spud leg protective device; comprise ocean platform body, spud leg, buoyancy aid, spiral dirty band, retainer ring and the flow deflector scraped; described ocean platform body below is provided with spud leg; on spud leg, cover has buoyancy aid; the spiral dirty band of scraping is installed under buoyancy aid; the spiral dirty band below of scraping is provided with retainer ring, and Fixing shrink ring is on spud leg.
Described spiral dirty being with as two helical pitch structures of scraping, two ends, left and right respectively have a joint to be connected with buoyancy aid.
Described retainer ring is provided with the flow deflector of multiple inclinations, contributes to spiral rotation of scraping dirty band.
Described spiral dirty band, retainer ring and the spud leg scraped is matched in clearance, and gap is 0.01mm.
Advantage of the present invention: the spiral dirt band of scraping is wrapped on spud leg, one end is fixed on buoyancy aid, buoyancy aid is enclosed within on spud leg, thereby drive the spiral dirt band of scraping being attached on spud leg to move along with fluctuating of wave drives buoyancy aid to move up and down or rotatablely move, thereby remove the marine growth adhering on spud leg.Spud leg spiral scraped dirty band not only can scrubbing, can also prevent that the vortex street that ocean current produces spud leg from vibrating the destruction to spud leg.And simple in structure, the feature such as moulding is unique, should there is the wide market space.
Brief description of the drawings
Fig. 1 is the structural representation of ocean platform spud leg protective device of the present invention;
In figure: 1, ocean platform body 2, spud leg 3, buoyancy aid 4, spirally scrape that dirt is with 5, retainer ring 6, flow deflector.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further illustrated.
Ocean platform spud leg protective device; comprise ocean platform body 1, spud leg 2, buoyancy aid 3, spirally scrape that dirt is with 4, retainer ring 5 and flow deflector 6; described ocean platform body 1 below is provided with spud leg 2; on spud leg 2, cover has buoyancy aid 3; buoyancy aid is provided with for 3 times spirally to be scraped dirt and is with 4, spirally scrape dirt and be with 4 belows that retainer ring 5 is installed, and retainer ring 5 is enclosed within on spud leg 2; can prevent from spirally scraping dirt and being with 4 to external diffusion, cannot closely cooperate with spud leg 2.
Describedly spirally scrape dirt and be with 4 for two helical pitch structures, two ends, left and right respectively have a joint to be connected with buoyancy aid 3, have Stability Analysis of Structures, the feature that scrubbing is effective.
Described retainer ring 5 is provided with the flow deflector 6 of multiple inclinations, and seawater is played to a guide functions, contributes to spirally to scrape dirt with 4 rotation, improves clean-up capability.
Describedly spirally scrape that dirt is with 4, retainer ring 5 is matched in clearance with spud leg 2, gap is 0.01mm, and biology is assisted a ruler in governing a country in can be good scrape, and keeps the intact of spud leg.
Using method of the present invention: spirally scrape dirt and be with 4 to be wrapped on spud leg 2, one end is fixed on buoyancy aid 3, buoyancy aid 3 is enclosed within on spud leg 2, be attached to spiral on spud leg 2 and scrape dirt and be with 4 motions along with thereby fluctuating of wave drives buoyancy aid 3 to move up and down or rotatablely move to drive, thereby remove the marine growth adhering on spud leg 2.Spud leg 2 spiral scrapes that dirt is with 4 not only can scrubbing, can also prevent that the vortex street that ocean current produces spud leg 2 from vibrating the destruction to spud leg 2, simultaneously easy to use.
