An integral-floating-box-type semi-submersible platform comprises an upper platform body and a lower floating body. Columns are connected between the upper platform body and the lower floating body, the lower floating body is an integral floating box, the upper surface and the lower surface of the floating box are parallel to the water surface, the vertical direction and the transverse direction of the floating box are consistent with the vertical direction and the transverse direction of the upper platform body, and the floating box extends along the vertical direction and the transverse direction of the upper platform body. At least three columns are connected between the upper platform body and the floating box and arranged at intervals along the vertical direction of the floating box, and the vertical section of each column is long-strip-shaped and is of a slice structure with two arc ends. The platform is small in draught, large in reserve cabin hold capacity, capable of keeping stable in storm and suitable for a shallow environment.
Description
Technical field
The present invention relates to floating platform on sea, be specifically related to adopt integral type buoyancy tank and schistose texture column, be applicable to half of the shallow-water environment type platform of diving.
Background technology
The half type platform of diving also claims the column stable platform, and its capacity of anti-storm is strong, has stability preferably, and the depth of water scope of adaptation is wide, and carrying capacity is large, is widely used in the operations such as probing, exploitation of marine oil and gas resource.Half dives the type platform mainly by lower buoyancy aid (or caisson), B-pillar and upper brace formation, upper brace is the carrier of life working space and equipment, column is connected between upper brace and lower buoyancy aid, plays a supportive role, and lower buoyancy aid is controlled the platform sinking degree of depth under water.Existing half latent type platform, be mostly deep water type, and its constructional feature is that lower buoyancy aid is caisson type or lower body formula, and the former establishes buoyancy aid under a caisson type for the below correspondence of every column, and the latter can be divided into two lower bodies and four lower body formulas.Half buoyancy aid of diving the type platform pulls the plug under operating condition, and the interval between upper brace must be much larger than the maximum wave height in marine site, place, thereby for the deep water type semi-submerged platform, its column is very high, generally more than 20 meters, whole podium level is very large, and the drinking water of this platform is large, from great, can't be applicable to shallow-water environment.
Summary of the invention
The applicant is improved for above-mentioned shortcoming of the prior art, and a kind of shallow draft, the partly latent type platform of deposit volume of compartment whole floating box type large, that be applicable to shallow-water environment are provided.
Technical scheme of the present invention is as follows:
The latent type platform of whole floating box type half, comprise upper brace, lower buoyancy aid, column is connected between upper brace and lower buoyancy aid, described lower buoyancy aid is the integral type buoyancy tank, the upper and lower surface of buoyancy tank all is parallel to the water surface, buoyancy tank vertically, laterally respectively with upper brace vertically, horizontal direction is consistent, and buoyancy tank along upper brace vertically, horizontal expansion; At least three columns are connected between upper brace and buoyancy tank, and column is along the longitudinal interval setting of buoyancy tank, and the vertical sectional shape of column is strip shape and the two ends schistose texture with arc.
Its further technical scheme is:
The length direction of described column is consistent with the horizontal direction of upper brace.
The length direction of described column is consistent with the longitudinal direction of upper brace, and at least two columns are respectively along being horizontally arranged at interval of buoyancy tank, and at least two columns are respectively along the longitudinal interval setting of buoyancy tank.
Described column is that vertical sectional shape is the schistose texture that two ends become semicircle, middle rectangularity.
Column inside is provided with heavily loaded elevator, pipeline passway and the walkway that is communicated with upper brace and buoyancy tank.
Technique effect of the present invention:
The present invention adopts the lower buoyancy aid of whole floating box type, shallow draft, improved the buoyancy of platform, can increase the load of upper brace, adaptation is used in shallow-water environment, the deposit volume of compartment of the goods and materials such as simultaneously, lower buoyancy aid acts as a fuel, water, under whole floating box type, buoyancy aid has improved the whole reserve power of platform, has increased the practicality of platform; The structure design of the lower buoyancy aid of whole floating box type, the fluid damping that has also improved platform, reduced platform waving in wave, improved the stability of platform in wave; Pillar construction is the long-pending strip shape schistose texture of small-waterplane-area, compares the cylinder-type column of conventional semi-submerged platform, improved the Joint strenght between upper platform and lower buoyancy aid, and inner space is larger, is convenient to arrange auxiliary facilities; The height of column and upper brace is less, is adapted to shallow-water environment, has reduced deadweight and displacement, thereby is conducive to reduce wind wave action; When wave force makes platform easily horizontal canting occur, the column of schistose texture can provide larger countermoment, thereby is conducive to overturn-preventing, improves the stability of platform in wave; Arrange column according to the flow path direction that comes of wave, make the strut length direction parallel with arrival bearing, be conducive to reduce the effect of wave force, can further reduce the motion of platform in wave, improve the stability of platform.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
All " vertically " related to refer to the direction of growing, and " laterally " refers to shorter direction.
See Fig. 1, Fig. 2, the present invention includes upper brace 1, lower buoyancy aid, column 3 is connected between upper brace 1 and lower buoyancy aid, upper brace 1 is cuboid or other suitable spatial structures, carrier for life working space and equipment, the lower surface of upper brace 1 is parallel to the water surface, described lower buoyancy aid is integral type buoyancy tank 2, buoyancy tank 2 upper, lower surface all is parallel to the water surface, buoyancy tank 2 vertically, laterally respectively with upper brace 1 vertically, horizontal direction is consistent, and buoyancy tank 2 is vertical along upper brace 1, horizontal expansion, and Cheng Fangti box type construction, four bights of buoyancy tank 2 are provided with the connection structure of arc, at least three columns 3 are connected between upper brace 1 and buoyancy tank 2, and column 3 is along the longitudinal interval setting of buoyancy tank 2, see Fig. 3, column 3 is strip shape and the two ends schistose texture with arc for vertical sectional shape, column 3 inside are provided with heavily loaded elevator 4, pipeline passway 5 and the walkway 6 that is communicated with upper brace 1 and buoyancy tank 2, be convenient between upper brace 1 and buoyancy tank 2 conveying people and goods, lay pipeline, can increase work efficiency.
The concrete arrangement of column 3 has multiple, Fig. 1 and Fig. 2 show the mode that column 3 is arranged along upper brace 1 horizontal expansion, the length direction that is column 3 is consistent with the horizontal direction of upper brace 1, longitudinal interval along buoyancy tank 2 arranges a plurality of columns 3 simultaneously, the arrangement of this kind of column 3, under the effect that enough Joint strenghts are provided, can reduce the usage quantity of column 3.
