Abstract
A floating support type small waterplane floating platform is a floating offshore platform, and is applicable to offshore oil development. A main floating body adopts a cylinder type; pillars are welded on the upper plane of the main floating body; transverse connecting bars are welded among the pillars; and a deck is welded at the tops of the pillars. The floating platform is characterized in that support rods are connected to the transverse connecting rods among the pillars through a hinged device; buoys are fixed at the other ends of the support rods; coupling chains are connected to the lower parts of the buoys; and the other ends of the coupling chains are connected with the outer wall of the main floating body through a coupling chain take-up and pay-off device. The floating platform has the effects that the main floating body applies buoyancy; when the angle of inclination of the floating platform is small, the coupling chains are in loose state, pillars provide floating stability; when the angle of inclination of the floating platform is large, the coupling chains are automatically tensed, at the moment, the buoys provide the floating stability; the buoys are connected with the main platform body through the support rods and the coupling chains; the support rods are connected with the main platform body in a hinged type; the tension of the coupling chains can be controlled; and the coupling chains are used for adjusting the buoyancy-applying time of the buoys. The platform is very suitable for oil drilling and production in deep-sea areas.
Description
Technical field
The utility model relates to ocean floating platform, particularly about a kind of deep-sea floating platform, is a kind of floating platform of suitable marine petroleum development.
Background technology
Along with the exploratory development of deep-sea oil, natural fuels, increasing floating type well drilling, oil production platform have obtained application.The platform pattern is varied, and semisubmersible platform, tension leg platform, open side type platform or the like have all obtained application to a certain degree, have also gained most valuable experience.In use also recognize the merits and faults of various platform patterns gradually, and constantly its structural detail is made amendment that various platform patterns have been passed through generations of renewal, the performance of structure is improved gradually.But because the abyssal environment inclement condition, various platform patterns are all standing huge test.In order to guarantee the comfort level and the safety of carrying out, guarantee staff on the platform smoothly of drilling well, oil extraction operation, floating platform also will possess enough floating stabilities and good hydrodynamic performance except needing enough bearing capacity and structural strength.Various platform patterns are also constantly progressively improved in these areas, to conform and to produce the demand of use.People never stop the research of deep-sea platform structure, do not have best platform pattern, have only better platform pattern.The utility model is exactly an idea that produces on the exploration road of new platform pattern, and has formed a deep-sea flat-bed notion pattern with this idea.
The utility model content
The purpose of this utility model is: a kind of floating support formula small-waterplane-area floating platform is provided, adopts main buoyancy aid and floating drum to cooperatively interact, make when platform is small to be rocked, floating drum energy free floating; When angle was rocked in the platform increasing, the connection chain tension made floating drum provide enough buoyancy for platform, is suitable for the needs of deep-sea oil exploitation.
The technical solution of the utility model is: floating support formula small-waterplane-area floating platform, and mainly by deck, strut, floating drum, pillar, connection chain, main buoyancy aid with hang down and swing plate and form.Main buoyancy aid is a cylinder type, and face bonding is connected to pillar on main buoyancy aid, is welded with horizontal pipe link between the pillar.Welded top at pillar has the deck.It is characterized in that: strut is connected on the horizontal pipe link of pillar by articulated mounting, and the other end of strut is fixed with floating drum.Bottom at floating drum is connected with connection chain, and the other end of connection chain is connected with the outer wall of main buoyancy aid by the connection chain draw off gear.
Described articulated mounting is: the end of strut is enclosed within on the horizontal pipe link, and strut can be an axle with horizontal pipe link, rotates in the vertical guide perpendicular to horizontal pipe link.
Described connection chain draw off gear is: at main buoyancy aid downside the volume bucket that can furl connection chain is installed, in order to adjust connection chain folding and unfolding state.
Being welded with pillar horizontal welding on pillar at the lower plane of main buoyancy aid is connected to hang down and swings plate.
The structure radial that described support and floating drum 3 are formed distributes, and the consitutional quantity of strut and floating drum is between 3～10.
The principle of work of the floating support formula small-waterplane-area floating platform of summary helps understanding the utility model.
Consult Fig. 1.One is sunken to undersurface cylinder type master buoyancy aid 6 buoyancy is provided; Supporting deck 1 on main buoyancy aid 6 tops by pillar 4 and pipe link; The sectional area of pillar 4 can be controlled very for a short time, to reduce the application force of wave to it; Around main buoyancy aid 6, be the center with main buoyancy aid 6, be distributed with a plurality of floating drums 3, for platform provides enough stabilities radially; Floating drum 3 links to each other with hinged pattern with pipe link by strut 2; Floating drum 3 bottoms link to each other with main buoyancy aid 6 by flexible connection chain 5; Between connection chain 5 and the main buoyancy aid 6 draw off gear is arranged, in order to adjust the degree of tightness state of connection chain 5, make platform when doing small rocking, floating drum 3 can free floating, and platform provides floating stability by pillar 4; When platform strengthens when rocking angle, away from main platform body, connection chain 5 is strained automatically, makes floating drum 3 begin to provide buoyancy for platform along the water surface for the floating drum of a side 3; By adjusting the connection chain draw off gear, adjust the relaxed state of connection chain, promptly to regulate the effect opportunity that connection chain is tightened up, thereby be set in platform when much inclination angles takes place, floating drum works; Being provided with below the main buoyancy aid 6 hangs down swings plate 7, reduces platform and hangs down and swing motion.
The beneficial effects of the utility model: floating support formula small-waterplane-area floating platform mainly has the following advantages:
What 1, the utility model waterplane part-structure adopted is corbeling, and its sectional area is less than other kinds platform, so it is subjected to the effect of wave load less relatively.
2, the utility model utilizes the effect of corbeling that certain stability can be provided in the ordinary course of things, guarantees the flat-bed normal operation, strengthens in load, and when platform motion was violent, the floating drum pole structure worked, and enough floating stabilities are provided.
3, the utility model floating drum pole structure adopts the pivotally attached form to link to each other with the horizontal pipe link of studdle, connection chain 5 then is to be in " relaxing " state in the ordinary course of things, like this floating drum pole structure be in the ordinary course of things " taking " on agent structure, application force is very little; And when the platform inclination angle became big, connection chain just was tightened up, and floating support structure is gone all out for platform provides anti-, guaranteed the flat-bed stability.
4, the draw off gear of the connection chain of the utility model setting when the platform drinking water changes, can be used for adjusting the effect opportunity of floating support structure.
