Problems solved by technology

[0002] Semi-submersible offshore platform, also known as column-stabilized drilling platform; semi-submersible offshore platform is a structure for oil production, drilling, exploration and other activities in the open sea and for its workers to provide production and living. Because it can go to deep sea operations, it is extremely It makes great use of marine resources, so it has been widely used; however, in the deep sea, due to the influence of large sea winds, it is difficult for offshore platforms to complete normal work and even cause destructive capsizing

Embodiment 1

[0038] Such as Figure 1-8 , a semi-submersible offshore platform 1 anti-capsulation device, including a pillar 3 and an expansion mechanism 2 installed at the bottom of the offshore platform 1, and a guide rail 6 is installed at the bottom of the In the middle, the expansion mechanism 2 includes an expansion plate 201, a driving mechanism, a rotating disc 202 and a disc support 5 for supporting the rotating disc 202. A groove 209 is formed on the rotating disc 202, and the disc The bracket 5 is installed under the rotating disk 202 on the column of the offshore platform 1, and the expansion plate 201 is installed on the edge of the offshore platform 1, and cooperates with the guide rail 6, and the fixed column 206 is installed on the expansion plate 201. The fixing column 206 is matched with the groove 209, the driving mechanism is installed on the column 3, and the driving mechanism is matched with the rotating disk 202.

[0039] Wherein, the guide rail 6 is used for guidin...

Embodiment 2

[0047] Such as Figure 9-11 , the difference from Embodiment 1 is that an adjustment mechanism 4 is also installed at the bottom of the pillar 3, and the adjustment mechanism 4 includes a first motor 401, a second motor 404, an external gear 407, a second gear 402, a connecting piece 4012, the external gear 407 is rotatably mounted on the pillar 3, a connecting piece 4012 is installed at the bottom of the external gear 407, an adjusting frame 403 is installed on the other end of the connecting piece 4012, and a threaded rod 408, The guide rod 409, the transmission mechanism 405 and the counterweight 406 installed on both sides of the threaded rod 408, the counterweight 406 is installed on the threaded rod 408, the second motor 404 is installed on one end of the adjustment frame 403, and the second Two motors 404 are connected with described threaded rod 408 by transmission mechanism 405, and described first motor 401 is installed on one side of pillar 3, and second gear 402 is...

Abstract

The invention discloses an anti-overturning device for a semi-submersible ocean platform, which comprises a pillar installed at the bottom of the ocean platform and an expansion mechanism, and a guide rail is installed at the bottom of the ocean platform, the pillar is installed in the middle of the ocean platform, and the expansion mechanism It includes an expansion board, a driving mechanism, a rotating disk and a disk support for supporting the rotating disk. There is a groove on the rotating disk, and the disk support is installed under the rotating disk on the column of the offshore platform. , the expansion board is installed at the edge of the ocean platform. Under the action of the driving mechanism and the rotating disk, the present invention can drive the expansion plate to extend to the outside of the ocean platform, increase the contact area between the ocean platform and seawater, improve the adsorption force of seawater to the ocean platform, and adjust the mechanism according to the direction of the wind, To adjust the position of the counterweight to ensure that the direction of the offshore platform in the direction of the sea wind is always lower than other directions, prevent the offshore platform from capsizing under the action of the sea wind, and ensure the safety of the offshore platform.

Description

technical field [0001] The invention belongs to the technical field of marine platforms, in particular to a semi-submersible marine platform anti-overturning device. Background technique [0002] Semi-submersible offshore platform, also known as column-stabilized drilling platform; semi-submersible offshore platform is a structure for oil production, drilling, exploration and other activities in the open sea and for its workers to provide production and living. Because it can go to deep sea operations, it is extremely It has been widely used because of the great use of marine resources; however, in the deep sea, due to the influence of large sea winds, it is difficult for the offshore platform to complete normal work and even cause destructive capsizing. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a semi-submersible offshore platform anti-overturning device, which can drive the expansi...
