Semi-submersible type anti-overturning device for ocean platform

Abstract

The invention discloses a semi-submersible type anti-overturning device for an ocean platform. The semi-submersible type anti-overturning device for the ocean platform comprises a rotating support arranged on the outer side of the ocean platform, a blade set, a power generating device and a control system; the rotating support comprises a lower base ring and an upper base ring, and the bottom of the lower base ring is movably connected with the ocean platform through a plurality of annularly and uniformly distributed hydraulic cylinders. The upper base ring is located above the lower base ring, and is connected with the lower base ring in a sliding manner, and the upper base ring can rotate around its center relative to the lower base ring. The blade set comprises a plurality of wing-shaped blades, and the wing-shaped blades are annularly and regularly arranged above the upper base ring; the wing-shaped blades are all arranged in the vertical direction, and the lower ends of the wing-shaped blades are adjustably connected with the upper base ring. An inner gear is arranged on the inner side of the upper base ring, and rotates along with the upper base ring, and the inner gear drives the power generating device to wok through a transmission mechanism. According to semi-submersible type anti-overturning device for the ocean platform, influences of sea wind on operation of the ocean platform can be effectively weakened, harm of ocean wind power is converted into electric energy, and wind power generation is clean, free of pollution, green and environment-friendly, and high insafety performance.

Description

technical field [0001] The invention relates to the technical field of new energy equipment, in particular to a semi-submersible offshore platform anti-overturning device. Background technique [0002] Semi-submersible offshore platform, also known as column-stabilized drilling platform. The semi-submersible offshore platform is a structure that provides production and life for oil production, drilling, exploration and other activities in the open sea and for its workers. It has been widely used because it can go to deep sea operations and make great use of marine resources. However, it is extremely vulnerable to large sea winds in the deep sea, which will make it difficult for the offshore platform to complete normal work and sometimes even cause destructive capsizing of the offshore platform. Contents of the invention [0003] In view of the deficiencies of the above-mentioned prior art, the purpose of the present invention is to propose a semi-submersible offshore plat...
