Offshore wind power submarine cable suitable for shallow sea area

Abstract

The invention discloses an offshore wind power submarine cable suitable for a shallow sea area, and belongs to the technical field of offshore wind power. Through the arrangement of a loss sensing displacement ball and a light reflecting exploring ball, when a certain position of a pressure-resistant protective sleeve is damaged and cracks are generated, seawater can flow into the pressure-resistant protective sleeve through the cracks so that a displacement agent absorbs water and expands, a displacement elastic air bag is compressed and shrunk, a driving and pullingelastic air bag is inflated and expanded, then the slotting pull rope is driven to pull down the elastic shading ball sleeve, the openable normally-closed seam is opened, a part of the light reflecting ball is exposed, and light reflection of the light reflecting ball can play a role in reminding and feedback; and when related workers inspect the pressure-resistant protective sleeve, whether the pressure-resistant protective sleeve at the position is damaged or not can be judged only by observing the light reflecting exploring ball and judging whether light reflection of the light reflecting ball can be observed or not so that the difficulty of inspection work can be remarkably reduced, the efficiency of the inspection work is greatly improved, and workers can simply and quickly complete the inspection work.

Description

technical field [0001] The invention relates to the technical field of offshore wind power, and more specifically relates to a submarine cable for offshore wind power suitable for shallow sea areas. Background technique [0002] Wind power is the fastest growing green energy technology in the world. While the construction of onshore wind farms is developing rapidly, people have noticed some restrictions on the utilization of onshore wind energy, such as large land occupation and noise pollution. Due to the abundant wind energy resources in the sea and the feasibility of today's technology, the ocean will become a rapidly developing wind power market. Offshore wind power is to use offshore wind resources to generate electricity. [0003] With the large-scale construction of offshore wind farms, submarine cables are the transmission medium of electric energy, and their safety and reliability are of paramount importance. Submarine cables are laid on the seabed, and their opera...

Problems solved by technology

In order to improve the protection of submarine cables, a protective sheath or protective layer is usually provided on the outside of the cable to protect the cable. However, due to the harsh environment of the seabed, the protective sheath will not only be washed and corroded by seawater, but may also be infested by submarine animals. , causing the protective cover to be easily damaged. Once the protective cover is damaged, its protective effect will be greatly reduced. Therefore, it is necessary to inspect the protective cover to find out the damage of the protective cover in time.

[0004] In prior art submarine cables for offshore wind power, it is necessary to carry out detailed inspection along the cable when inspecting the protective cover. Due to the difficulty and danger of the submarine operation itself, the inspection work of the protective cover Very cumbersome and less efficient
