Automatic toppling centering device for single point mooring floating type structure

Abstract

Disclosed is an automatic toppling centering device for a single point mooring floating type structure. The automatic toppling centering device is characterized in that the automatic toppling centering device is installed between a floating body and a floating body mooring anchor chain and comprises a supporting structure which is installed on the lower end face of the floating body and extends towards the portion below the floating body, a centering swing arm is installed below the supporting structure and movably connected with the supporting structure, a weight is installed below the centering swing arm, and the mooring anchor chain is connected to the portion below the weight. The automatic toppling centering device is simple in structure, easy to produce, manufacture and install, and particularly suitable for being used on the single point mooring ocean floating type structure of the same size, the seakeeping of the floating body in waves is improved, automatic centering can be achieved after the floating body topples, and the safety of the automatic toppling centering device is ensured.

Description

technical field [0001] The invention belongs to the technical field of marine engineering machinery and relates to an anti-overturning structure of an ocean floating body, in particular to an automatic righting device after overturning of a single-point mooring floating structure. Background technique [0002] Single point mooring floating structure is a general term for a type of marine floating structure. This type of structure usually includes a floating body on the sea surface and an anchor chain for mooring the floating body. The floating body is fixed at a certain point in the ocean by mooring. For example, various data buoys and ship marks for marine environment monitoring, float-type wave energy devices that use wave energy to generate electricity, and navigation lights for ship piloting, etc. [0003] The deck or floating body cabin of this type of structure is usually equipped with various instruments and equipment to achieve specific functions. Taking the marine ...

Problems solved by technology

Although the stability calculation of this type of structure is carried out at the beginning of construction, for example, in order to increase the stability of the floating body, heavy objects are usually installed in the floating body cabin to increase the ballast of the floating body to lower the center of gravity of the floating body and increase the stability of the floating body. However, this structure will occupy the available space in the floating body cabin, and it is still possible to capsize under extreme sea conditions or accidental collision of ships, and once capsized, it cannot self-righte, causing losses
