Dynamic cable protection system and wind power system

Abstract

The invention provides a dynamic cable protection system and a wind power system.The dynamic cable protection system comprises a dynamic cable, a plurality of first buoyancy devices, a plurality of second buoyancy devices and a plurality of first connecting devices, and the dynamic cable is located in a water area environment; the dynamic cable is used for transmitting signals or electric energy between water surface equipment and underwater equipment, the multiple first buoyancy devices are arranged on the dynamic cable at intervals, and the second buoyancy device floats on the water surface; the second buoyancy devices are connected with the dynamic cables through the first connecting devices, and the connecting positions of the first connecting devices and the dynamic cables are located between the two adjacent first buoyancy devices. The second buoyancy device is used for limiting the lowest position of a trough section of the dynamic cable, and the trough section is connected between two adjacent crest sections. The device is used for preventing the dynamic cable from being bent and contacted with the seabed surface to influence the use and service life of the dynamic cable.

Description

technical field [0001] The invention relates to the technical field of offshore wind power generation, in particular to a dynamic cable protection system and a wind power system. Background technique [0002] As a special power and signal transmission medium, dynamic cables play an indispensable role in power transmission and communication control signal transmission in the marine industry. For example, in floating wind power generation, dynamic cables are required to transmit the generated electrical energy out of the wind farm. In the development of offshore oil and gas, dynamic submarine cables are required to supply power to platforms and equipment. Offshore new energy power generation, underwater observation, and scientific investigations require dynamic cables to transmit electrical energy. [0003] The dynamic cable is suspended in the water. Under the combined action of multiple factors such as marine hydrology and meteorology, large displacement, bending and torsion...

AI Technical Summary

Problems solved by technology

[0003] The dynamic cable is suspended in the water. Due to the joint action of multiple factors such as ocean hydrology and meteorology, large displacement, bending, and torsion will inevitably occur. If the dynamic cable bends too much, the suspended part in the water will move downward and will come into contact with the seabed. At this time, if the dynamic cable moves and twists, it will contact the seabed. Repeated friction on the surface seriously affects the use and life of the dynamic cable

[0004] Therefore, there is an urgent need for a dynamic cable protection system and a wind power system to prevent the line shape of the dynamic cable from being pushed down and touching the seabed, which will affect the use and life of the dynamic cable
