Marine large foldable floating body

Abstract

The invention relates to the field of offshore floating platforms, in particular to an offshore large foldable floating body which is formed by sequentially connecting a plurality of floating body blocks in series through a rotating mechanism, the floating body blocks can rotate by a certain angle through the rotating mechanism to achieve switching between the folding state and the unfolding state of the floating body, and the area of the floating platform can be effectively expanded. Meanwhile, the offshore large floating platform can be quickly towed. When in a folded state, the structure is compact, rapid transportation is facilitated, and when in an unfolded state, the overall size is multiplied, and the area of the platform is effectively enlarged. The device can be used for carrying offshore new energy conversion equipment such as a wind driven generator, photovoltaic power generation equipment and a wave energy converter, and can also be used for offshore cage culture, offshore hydrogen production and other scenes.

Description

technical field [0001] The invention relates to the field of floating platforms on the sea, more specifically, to a large-scale foldable floating body on the sea. Background technique [0002] The development of large offshore floating platforms has been greatly restricted due to their huge size, difficult manufacturing, high cost, and long cycle time. The common forms of large-scale floating platforms include box type, semi-submersible type and grid type. The box-type floating platform has a simple structure and is greatly affected by waves. A large flexible floating platform can be formed by hinged multiple box-type floating bodies; semi-submersible type Floating platforms are less affected by waves, the overall structure is rigid design, and large-scale construction costs are high; grid-type floating platforms are a large-scale, fast-deployable structure that weakens the impact of waves and has high cost performance. [0003] There are two problems in the construction me...

AI Technical Summary

Problems solved by technology

[0003] The construction method of the above-mentioned large-scale floating platform has two problems that have not been resolved. First: how to effectively expand the area of ​​the floating platform. Although the grid-type floating platform can be deployed on a large scale, the deployment density is too high; second: the large-scale floating platform. Generally located in sea areas far from the coast, the floating platform itself has no power, and needs to be towed to the designated location after the overall construction. The towing speed is very slow, and the purpose of rapid deployment cannot be achieved.

[0004] The patent with publication number CN107140144A provides a super large floating platform at sea. The integrated pentagonal closed structure design greatly expands the area of ​​the floating platform, but it emphasizes the integrity of the structure and ignores the overall towing speed. It also ignores the construction cycle

The patent with publication number CN105984566A provides a fast-navigating offshore platform. The semi-submersible design can solve the problem of fast navigation, but the platform area cannot be expanded.
