Problems solved by technology

[0003] Therefore, the technical problem to be solved by the present invention is that when the mooring platform in the prior art adopts the mooring anchor winch to pull the mooring line, the mooring line is inclined , the force used for pre-tensioning in the horizontal direction is less than the traction force exerted by the mooring anchor winch. In order to meet the pre-tensioning requirements, the power of the mooring anchor winch is required to be larger, and the size of the anchor winch is also larger. The mooring platform is particularly It is difficult to arrange large-sized anchor winches on the floating wind turbine platform, and the mooring platform needs to be equipped with a high-power generator to provide power for the mooring winch, which is costly

Abstract

The invention relates to the technical field of catenary mooring systems, and provides a catenary adjusting device and a mooring system.The catenary adjusting device comprises a main body with a hollow inner cavity; the guide piece is arranged in the inner cavity of the main body, and a receding channel is formed in the area between the guide piece and the inner wall of the main body; an inlet of the receding channel is located in the side face of the body, an outlet of the receding channel is located in the top face of the body, and the receding channel is suitable for changing the extending direction of the driving anchor chain after the driving anchor chain penetrates. According to the adjusting device, after the driving anchor chain penetrates out of the receding channel, the driving anchor chain extending horizontally is forced to change the direction, the driving anchor chain extending to the water surface is made to extend in the vertical direction, the traction force is made to be equal to the pre-tensioning force, force loss is reduced, the requirement for the power of a winch is lowered, the size of the winch is reduced, and the service life of the winch is prolonged. The installation difficulty is reduced and the cost is saved; and moreover, component force in the vertical direction can be avoided, the anchor cannot be pulled out, and the reliability of the mooring anchor can be improved.

Description

technical field [0001] The invention relates to the technical field of catenary mooring systems, in particular to a catenary adjusting device and a mooring system. Background technique [0002] When the mooring line of the existing mooring system needs to be adjusted, it is mainly realized by the mooring anchor winch on the mooring platform or releasing the mooring line. Since the mooring anchor is located underwater, the mooring anchor winch is used to pull the mooring line. When the mooring line is in the shape of a large inclination angle, the force used for pre-tensioning in the horizontal direction is less than the traction force applied by the mooring anchor winch. In order to meet the pre-tensioning requirements, the power of the mooring anchor winch is required to be larger. The size of the anchor winch is also large, and it is difficult to arrange a large-size anchor winch on the mooring platform, especially the floating wind turbine platform, and the mooring platfo...
