Dynamic cable arrangement structure for offshore wind power generation

Technical Field

The utility model relates to the technical field of cables, in particular to a developments cable arrangement structure for offshore wind power generation.

Background

With the development of offshore floating wind power, the demand for dynamic cables between wind turbines is increasing. The external loading of the dynamic cable typically comes from the dynamic loading of the floating platform, as well as the wave stream loading in the marine environment. In order to protect the dynamic cable, the problem that the dynamic cable is damaged by overbending or pressing of the cable at a mud contact point is avoided. The traditional dynamic cable generally adopts a single wave form to form mud contact point protection for the dynamic cable. The single wave line type needs to form a line type on each floating type fan to ensure that the dynamic cable at the lower part of the fan platform is well protected. This results in the cable body being prone to over-bending and pinching when touching the ground and the cable body being of excessive length.

Detailed Description

The invention is further explained by combining the attached drawings.

Referring to fig. 1 to 4, the arrangement structure of the dynamic cable 2 for offshore wind power generation includes a dynamic cable 2 for connecting two floating fan modules 1, a buoyancy module for providing buoyancy is installed on a middle section of the dynamic cable 2, the middle section of the dynamic cable 2 is floated in water by the buoyancy module to form a floating section, and the floating section makes the dynamic cable 2 be W-shaped as a whole.

The buoyancy module comprises a number of buoyancy blocks 3 mounted on the dynamic cable 2. So that the body of the dynamic cable 2 floats in the water to form a W-shape. The problems of over-bending and pressing caused by the grounding of the cable body are avoided, and the length of the cable body is saved.

Two or more buoyancy modules are arranged on the middle section of the dynamic cable 2 at intervals, so that two or more floating sections are arranged on the dynamic cable 2. Enough cable length can be ensured for connection. In addition, the dynamic cable 2 is also provided with a gravity module beside the buoyancy module. Through the improvement, the stability of the cable body hanging part of the dynamic cable 2 can be ensured.
