Description

Technical Field

[0001] The utility model relates to the technical field of cable protection devices, in particular to a protection device for exposed cabin-penetrating cables of an offshore booster station. Background Art

[0002] With the rapid development of offshore wind power in my country, offshore wind farms are moving farther from shore, deeper into the water, and possessing greater capacity. As a key component connecting offshore wind turbines to the power grid, booster stations are also experiencing increasing capacity and weight. The largest offshore booster station in China has a capacity of 1,000MW, with topside modules often weighing over 6,000 tons. As offshore booster platforms carry increasing capacity, the number of internal electrical equipment increases, and the structure becomes increasingly compact, making it very easy for cables to be partially exposed during cabling.

[0003] The marine environment is characterized by high humidity and salt spray. Exposed cables are susceptible to corrosion, leading to reduced insulation performance and increasing the risk of short circuits and failures. Exposed cables on offshore booster platforms are more susceptible to mechanical impact or friction, causing damage and compromising the stability and safety of power transmission. Once exposed cables are exposed, maintenance and repair work becomes more difficult and costly due to the unique characteristics of the offshore environment. Utility Model Content

By placing the cables in the inner cavity of the box, the exposed portion of the cables outside the wall is shielded and protected, effectively preventing the exposed cables from being damaged by collisions. In order to achieve the above technical features, the purpose of this utility model is achieved as follows:

[0005] A protective device for exposed cables in an offshore booster station comprises a box body, wherein a first opening and a second opening are respectively provided on the back and the bottom of the box body for the cables to pass through, wherein the first opening is connected to the second opening;
