Embodiment Construction

[0019] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0020] see Figure 1~5 , a protection and damping device for an offshore platform, which is installed in the wave fluctuation area of ​​the leg 1 of the offshore platform, and is characterized in that it includes a "scissor type" displacement amplification device 2, a laminated rubber support 3, an upper support platform 4, and a middle support Platform 5, lower supporting platform 6, limit device 7, ice-breaking cone 8, grooved connecting plate 9 and bolts 10; the upper supporting platform 4, middle supporting platform 5, and lower supporting platform 6 are fixed on pile legs 1, The "scissors-type" displacement amplifying device 2 is composed of two curved rods connected by a hinge; one end of one curved rod is welded on the upper bearing platform 4, and the other end is welded on the limiting device 7, One end of another curved rod is hinged on the ice-bre...

Abstract

The invention relates to a protection and damping device for an ocean platform, and belongs to the technical field of ocean structures. The device comprises a scissors type displacement magnifying unit, a lamination rubber support, an upper part support platform, a middle part support platform, a lower part support platform, a spacing unit, an ice breaking conical surface body, a groove-shaped connection plate and a bolt. The device is axially symmetric when taking the middle part support platform as a symmetric axis, and is also axially symmetric when taking a pile leg as a symmetric axis. The device can reduce horizontal stiffness of a conical body less, has better resilience and energy consumption damping performance, can reduce compression, friction and vibration effects of ice and wave excitation on the structure effectively, the response of the platform is reduced, and ice-excited vibration problem of the ocean platform is fundamentally solved.

Description

technical field [0001] The invention relates to an ocean platform protection and vibration reduction device, which belongs to the technical field of ocean structures. Background technique [0002] my country's Bohai Sea and northern seas are often hit by cold waves in winter, and there is ice formation every year, and the frequency of sea ice disasters. my country's Bohai Sea has proven and developed a number of oil fields and established a number of oil platforms, and the oil development process is facing sea ice disasters. In frozen seas, sea ice has a greater effect on ocean structure than waves and wind. Sea ice drifts under the action of currents and winds and collides with offshore platform structures. [0003] During the construction and service period of structures in ice regions, a large amount of blocked ice between pile legs of offshore platforms will be squeezed, cut and broken between piles due to the action of tidal currents and winds, posing a threat to the ...
