The invention relates to an integrated damping plate for an ocean platform, and belongs to the technical field of ocean engineering.
Background
With the rapid expansion of world population and world economy, the demand for energy is rapidly increased, land resources are exhausted gradually, the survival and development of human beings are more and more dependent on sea, and the development and utilization of ocean energy and the like are realized through ocean platforms. Ocean platforms are used as an infrastructure for operation in the sea and are in a severe and complex environment for a long time, and due to the action of wind load and wave load, accidents of structural damage occur, which cause a great deal of economic loss and environmental pollution, and sometimes even influence the life safety of staff. In order to better maintain the normal operation and production of the ocean platform, the influence of waves needs to be reduced as much as possible to keep the ocean platform stable, the existing ocean platform mostly adopts an isolated disc type damping plate to inhibit heave motion, and the isolated damping plate damages the integrity and the integral rigidity of the structure and has poor heave response performance. In the prior art, cantilever beams are additionally arranged between a floating body and a damping plate to increase the overall strength, but the structural fracture is frequently caused due to the fact that the stress area is too concentrated, so that improvement is needed.

The technical scheme adopted by the invention is as follows: the integrated damping plate comprises three pontoons, an integrated damping plate and a T-shaped steel structure fixed on the integrated damping plate, wherein the T-shaped steel structure comprises three regular hexagonal structures, three first T-shaped steel and three second T-shaped steel, one ends of the first T-shaped steel and the second T-shaped steel are firstly connected with the first regular hexagonal structures, the other ends of the first T-shaped steel and the second T-shaped steel are connected with the second regular hexagonal structures, one ends of the first T-shaped steel and the second T-shaped steel are then connected with the second regular hexagonal structures, the other ends of the first T-shaped steel and the second T-shaped steel are also connected with the third regular hexagonal structures, and the other ends of the first T-shaped steel and the second T-shaped steel are connected with the first regular hexagonal structures to form a triangular T-shaped steel structure; the three buoys are respectively arranged at the middle position of the regular hexagonal structure, each inner angle of the regular hexagonal structure is respectively extended out of one third T-shaped steel to be fixedly connected with the buoys, the upper parts of every two buoys are fixedly connected by adopting a horizontal connecting rod, each buoy is fixedly connected with the second T-shaped steel by adopting two diagonal bracing connecting rods, and each third T-shaped steel is provided with a triangular support plate fixedly connected with the corresponding buoy.
The T-shaped steel structure adopts a welding structure, and the integrated damping plate is fixed at the lower part of the T-shaped steel structure by adopting the welding structure.
The outer edge line of the integrated damping plate is the outline of the outer side of the three first T-shaped steels and three sides of the three regular hexagonal structures, and the inner edge line is the through hole of an unequal hexagon formed by the inner side of the three second T-shaped steels and one side of the three regular hexagonal structures.
The beneficial effects of the invention are as follows: the integrated damping plate for the ocean platform changes an isolated type into a through integrated type. The design adopts an integral large-area plate structure, and can provide larger damping area and better damping effect. When the ocean platform is influenced by wind load and wave load to generate heave motion, the integrated damping plate can provide a damping effect acting on the whole ocean platform, so that the influence of heave motion on the ocean platform is reduced, and the stability of the whole ocean platform is maintained.
The triangular support plate at the bottom of the pontoon can strengthen the connection between the pontoon and the bottom of the ocean platform, and the stress can be more uniformly distributed due to the adoption of the connection between the surfaces, so that the stress can not be concentrated at a certain point to cause structural damage.
T shaped steel on the damping plate can increase the intensity of the integrated damping plate in bottom, prevents the deformation that produces because of the inhomogeneous atress of bottom damping plate. The outer side of the damping plate adopts a tip-removing design, so that stress concentration is prevented, the construction is simple, and the construction cost is saved.
Compared with the prior art, the whole ocean platform is simpler and faster to build, and the fund and the building time are saved; the structure strength is high, the damage of the whole ocean platform caused by the damage of the local connecting piece is avoided, and the offshore production operation is facilitated throughout the year.
