Abstract
A semi-submersible type deepwater work platform comprises a sealed type steel floating body, an above water platform, steel stand columns and a tension type anchoring device. The sealed type steel floating body is formed by pairwise splicing six same approximately-trapezoidal floating units, and a regular hexagonal through hole is formed in the center of the sealed type steel floating body. The above water platform is a regular hexagonal column body, and the six steel stand columns are perpendicularly and evenly distributed between the spliced sealed type steel floating body and the above water platform; the tension type anchoring device is composed of a balancing weight, a pulley, a steel wire rope and an anchoring machine; and the pulley is fixed to the top of the balancing weight, and the steel wire rope strides the pulley to be connected with the sealed type steel floating body and the above water platform. The semi-submersible type deepwater work platform has the advantages that the work platform is simple in structure, convenient to assemble, and low in cost, in the working process, most of the structure is located in a deepwater area, the platform is located above a water surface, so that the influence of waves on the platform is small, the overall stability is good, and the platform is suitable for above water work of above water throw filling, underwater slope arranging, ship unloading, cargo transferring and the like of deepwater breakwaters
Description
Technical field
The invention belongs to platform technical field, be specifically related to a kind of semisubmersible deepwater work platform.
Background technology
Along with the scale of China's port construction is increasing, the construction at harbour, towards the more severe deep water regional development of natural conditions, in order to make there is good hydrologic condition in port, just the deepwater regions outside port must build break-water.And wind and waves often appears in these deepwater regions, bring very big inconvenience to building of break-water.
Be limited to water surface area in port, the depth of water or conveniently, sometimes need deepwater regions outside port to carry out ship loading and unloading and cargo transfer operation.
Show according to the research of wave theory and test, the concentration of energy of wave, on water body top layer, has concentrated 98% of whole wave energy within the scope of the depth of water of three times of wave height below the water surface.
Semisubmersible platform is a kind of platform, is developed by bottom-supported platform, and it has platform deck, does not attack more than the water surface by wave, under have buoyancy aid, be sunken to below the water surface to reduce the disturbance force of wave, be connected to therebetween be the column of small-waterplane-area.Because semisubmersible platform has less waterplane area, make the motor imagination of whole platform in wave less, thus it has outstanding deepwater work performance.
Summary of the invention
The object of the invention is for above-mentioned technological analysis, provide a kind of semisubmersible deepwater work platform, this semisubmersible deepwater work platform structure is simple, easy to assembly, cost is low, and during work, major part structure is positioned at abyssal zone, and little by wave effect, resistance to overturning is good.
Technical scheme of the present invention:
A kind of semisubmersible deepwater work platform, comprise hermetic type steel buoyancy aid, above water platform, steel column and tension type anchoring arrangement, hermetic type steel buoyancy aid is spliced to form between two by six pieces of identical approximate trapezoid float member, is hermetic type regular hexagon cylinder, in be formed centrally regular hexagon through hole; Above water platform is regular hexagon cylinder; Six roots of sensation steel uprights vertical be distributed in can assembled hermetic type steel buoyancy aid with between above water platform and by bolt respectively with can assembled hermetic type steel buoyancy aid and above water platform be connected, point of connection is positioned at leg-of-mutton center corresponding to each limit of above water platform; Tension type anchoring arrangement is made up of clump weight, pulley, steel rope and windlass, and pulley is fixed on the top of clump weight, and steel rope strides across pulley, and one end is connected with the outer point of hermetic type steel buoyancy aid, and the other end is connected with the windlass at above water platform summit place; Hermetic type steel buoyancy aid is positioned at below the water surface, and its buoyancy provided is greater than the gravity of semisubmersible deepwater work platform self.
The upper base edge lengths of described trapezoidal float member is 5 meters, and bottom length is 30 meters, and wall thickness is 30 millimeters, and the height of regular hexagon cylinder is 1.4 meters; The length of side of above water platform regular hexagon cylinder is 15 meters, is highly 1 meter; The external diameter of steel column is 1 meter, and wall thickness is 100 millimeters, is highly 25 meters.
Advantage of the present invention and effect are:
This semisubmersible deepwater work platform is by can the tension type anchoring arrangement of assembled hermetic type steel buoyancy aid, steel column, above water platform and band counterweight form, structure is simple, easy to assembly, cost is low, during work, major part structure is positioned at abyssal zone, platform is positioned at more than the water surface, little by wave effect, resistance to overturning is good, is applicable to the throwing waterborne of deep water break-water, under water whole slope, the operation at sea such as ship loading and unloading and cargo transfer.
