Problems solved by technology

Although the ice will be broken, the broken ice will be attached to the structure or cause structural damage to the column for the second time due to wind and current, and the rise or fall of the water level due to tides or global warming will make the Columns have to withstand more complex environmental factors

Embodiment Construction

[0023] Such as Figure 1 to Figure 5 As shown, it includes a column 1, a structural strengthening device 2, a shock absorbing device 3, and an adaptive tidal floating self-elevating device 4. figure 2 By figure 1 The cross-sectional view at A-A of , which shows the components inside the structural reinforcement device 2. The structural strengthening device 2 includes a truncated conical lower cone 8, on which several wave-absorbing holes 21 are arranged, and the surface of the wave-absorbing holes is a 65° rhombic three-dimensional shape, which greatly reduces the resistance of the incoming flow and at the same time It can also enhance the efficiency of ice breaking. Brackets 23 are provided at intervals around the surface of the lower cone 8, and the brackets 23 extend from the top of the upper cone 7 to the bottom of the upper cone 7, and the brackets 23 are fixed with reinforced angle steel 24, each with a One is fixed with the bracket 23 and the lower end of the reinfo...

Abstract

The invention discloses an ice-resistant device applicable to a polar ice zone ocean platform.The ice-resistant device comprises a self-adaptive tide floating type self-elevating device and a structure strengthening device, the structure strengthening device is located above the self-adaptive tide floating type self-elevating device and comprises a circular-cone-shaped lower cone, multiple wave absorbing holes are formed in the lower cone, a first partition plate is arranged on the inner side of the lower cone and connected with a second partition plate through multiple inclined struts which are mutually connected in a staggered mode, multiple damping devices are connected between the first partition plate and the second partition plate, and the second partition plate is arranged on a stand column in a sleeving mode.According to the ice-resistant device applicable to the polar ice zone ocean platform, by means of the damping device, the self-adaptive tide floating type self-elevating device and the structure strengthening device, damping and strength requirements of the structure can be effectively strengthened, and meanwhile the ice-resistant effect can be flexibly carried out by adapting to rising or falling of the tide water level.

Description

technical field [0001] The invention relates to an anti-icing device suitable for ocean platforms in polar ice regions, and belongs to the field of anti-icing devices. Background technique [0002] With the development of marine engineering technology, people are increasingly aware of the importance of marine engineering equipment, among which the safety of marine engineering structures is the most important, and the reliability of its marine engineering structures is an important indicator to ensure its normal production operations and survival One, the security of the platform structure has attracted more and more attention from relevant parties. Polar regions have vast resources, but at the same time there are complex ice regions and severe weather, which pose great challenges to the design and construction of offshore platforms. In the polar regions, there are formed or broken ice cubes scattered on or under the water surface all year round in winter, and the sea surfac...
