Abstract
Ocean platform pile leg protection device, belong to oceanographic equipment field, including ocean platform body, spud leg, buoyancy aid, spiral scraping dirt band, retainer ring and flow deflector, below described ocean platform body, spud leg is installed, buoyancy aid it is cased with on spud leg, spiral scraping dirt band is installed under buoyancy aid, below spiral scraping dirt band, retainer ring is installed, and Fixing shrink ring is on spud leg, the present invention spiral scraping dirt band is wrapped on spud leg, one end is fixed on float, float is enclosed within spud leg, along with wave fluctuate drive float move up and down or rotary motion thus drive be attached on spud leg spiral scraping dirt band motion, thus remove the marine growth of attachment on spud leg.The spiral scraping dirt band of spud leg not only can scrubbing, moreover it is possible to prevent vortex street vibration that spud leg produces by the ocean current destruction to spud leg.This spud leg protection device simple in construction, moulding uniqueness, the most easy to use.
Description
Technical field
The present invention relates to ocean platform pile leg protection device, belong to oceanographic equipment field.
Background technology
Ocean platform, at sea carry out drilling well, oil recovery, transporting something containerized, observe, navigate, the movable offer such as construction produces and the structures of living facilities.Its architectural characteristic and duty can be divided into fixed, movable and semi-fixed type three major types.The bottom of fixed platform is directly supported by stake, expansion footing or other structures and is bonded to seabed, is divided into pile foundation type and gravity type two kinds 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.The most studying the semi-fixed type ocean platform of novelty, it can be fixed in deep water, has again high movable, and tension leg type platform i.e. belongs to this type of.At present most of platforms be designed with spud leg; the whether firm direct relation of ocean platform pile leg the safety of platform; but the bad environments residing for spud leg; not only washed away impact also by the attached corrosion of marine growth by wave; therefore it is not added with protection and can have a strong impact on its life-span, be currently a urgent problem.
Summary of the invention
It is an object of the invention to provide ocean platform pile leg protection device.
The problem to be solved in the present invention is the deficiency that ocean platform pile leg is easily subject to the attached corrosion washing away impact and marine growth of wave.
Ocean platform pile leg protection device; including ocean platform body, spud leg, buoyancy aid, spiral scraping dirt band, retainer ring and flow deflector; below described ocean platform body, spud leg is installed; buoyancy aid it is cased with on spud leg; spiral scraping dirt band is installed under buoyancy aid; below spiral scraping dirt band, retainer ring is installed, and Fixing shrink ring is on spud leg.
Described spiral scraping dirt band is double helical pitch structures, and two ends, left and right are respectively arranged with a joint and are connected with buoyancy aid.
Described retainer ring is provided with the flow deflector of multiple inclination, contributes to the rotation of spiral scraping dirt band.
Described spiral scraping dirt band, retainer ring and spud leg are matched in clearance, and gap is 0.01mm.
Advantages of the present invention: spiral scraping dirt band is wrapped on spud leg, one end is fixed on buoyancy aid, buoyancy aid is enclosed within spud leg, along with wave fluctuate drive buoyancy aid to move up and down or rotary motion thus drive the spiral scraping dirt band motion being attached on spud leg, thus remove on spud leg the marine growth of attachment.The spiral scraping dirt band of spud leg not only can scrubbing, moreover it is possible to prevent vortex street vibration that spud leg produces by the ocean current destruction to spud leg.And the feature such as simple in construction, moulding uniqueness, should have the wide market space.
Accompanying drawing explanation
Fig. 1 is the structural representation of ocean platform pile leg protection device of the present invention；
In figure: 1, ocean platform body 2, spud leg 3, buoyancy aid 4, spiral scraping dirt band 5, retainer ring 6, flow deflector.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment the present invention is further illustrated.
Ocean platform pile leg protection device; including ocean platform body 1, spud leg 2, buoyancy aid 3, spiral scraping dirt band 4, retainer ring 5 and flow deflector 6; below described ocean platform body 1, spud leg 2 is installed; buoyancy aid 3 it is cased with on spud leg 2; buoyancy aid is provided with spiral scraping dirt band 4 for 3 times, is provided with retainer ring 5 below spiral scraping dirt band 4, and retainer ring 5 is enclosed within spud leg 2; spiral scraping dirt band 4 can be prevented to external diffusion, it is impossible to closely cooperate with spud leg 2.
Described spiral scraping dirt band 4 is double helical pitch structures, and two ends, left and right are respectively arranged with a joint and are connected with buoyancy aid 3, have Stability Analysis of Structures, the feature that scavenging effect is good.
Described retainer ring 5 is provided with the flow deflector 6 of multiple inclination, and sea water plays a guide functions, contributes to the rotation of spiral scraping dirt band 4, improves clean-up capability.
Described spiral scraping dirt band 4, retainer ring 5 are matched in clearance with spud leg 2, and gap is 0.01mm so that it is good scraping can assist a ruler in governing a country biology, keep the intact of spud leg.
The using method of the present invention: spiral scraping dirt band 4 is wrapped on spud leg 2, one end is fixed on buoyancy aid 3, buoyancy aid 3 is enclosed within spud leg 2, along with wave fluctuate drive buoyancy aid 3 to move up and down or rotary motion thus drive the spiral scraping dirt band 4 that is attached on spud leg 2 to move, thus remove the marine growth of attachment on spud leg 2.The spiral scraping dirt band 4 of spud leg 2 not only can scrubbing, moreover it is possible to prevent vortex street vibration that spud leg 2 produces by the ocean current destruction to spud leg 2, the most easy to use.
