Abstract

The invention discloses an arranging and maintaining scheme for electrical equipment on a foundation platform of an offshore wind turbine jacket. The arranging and maintaining scheme comprises the following steps: firstly, arranging one or more outer carrying platforms on the foundation platform of the offshore wind turbine jacket, and using the space of the outer carrying platforms to build one or more electrical equipment containing rooms and/or maintaining equipment temporary containing rooms and/or rest rooms on the outer carrying platforms according to the needs; secondly, arranging one or more cranes in the electrical equipment containing rooms and/or maintaining equipment temporary containing rooms of the outer carrying platforms, and forming hatches for passing through heavy objects hoisted by the crane on the electrical equipment containing rooms and/or maintaining equipment temporary containing rooms; thirdly, using the space of the outer carrying platforms for directly hoisting equipment to the outer carrying platforms from a barge on the sea; or directly hoisting equipment to the barge from the outer carrying platforms. The purpose of the invention is to provide the arranging and maintaining scheme for electrical equipment on the foundation platform of the offshore wind turbine jacket, which has large space, good maintenance, convenience in hoisting and maintaining, and good heat dispersion and fireproofing.

Example Embodiment

[0022] like Figure 1 to Figure 4 As shown, the layout and maintenance plan of electrical equipment on the foundation platform of the offshore wind turbine jacket: Firstly, set up one or more outrigger platforms 3 on the foundation platform 1 of the offshore wind turbine jacket, and then use the space of the outrigger platform 3 to install the outer platform 3 Build one or more electrical equipment storage rooms 4 and/or maintenance equipment temporary storage rooms 5 and/or rest rooms on demand;
[0023] Then: configure one or more cranes 6 as required in the electrical equipment storage room 4 and/or maintenance equipment temporary storage room 5 of the external platform 3, and temporarily place them in the electrical equipment storage room 4 and/or maintenance equipment There is a hatch 7 for the crane 6 to hoist heavy objects to pass through on the room 5;
[0024] And then: using the outside space, the crane 6 can directly lift equipment from the barge at sea to the platform; during maintenance, the crane 6 can directly replace objects with the barge at sea through the hatch, such as oil, large or Heavy maintenance tools, etc., can not only save maintenance costs, but also ensure the safety of heavy electrical parts during replacement; or directly hoist equipment from the external lifting platform to the barge.
[0025] The solution of the present invention utilizes the existing basic platform and the overhanging platform to build a placement room, fully expands the placement space of electrical equipment, and can arrange electrical equipment as required to ensure a safe distance between electrical equipment and maintain space; in addition, Temporary rest rooms for operating personnel can be designed on demand, advocating humanized design and reflecting humanistic care.
[0026] Further improvement: a sealed hatch cover can also be connected to the hatch 7, and the sealed hatch cover is covered to seal the hatch 7 to prevent water vapor from entering, so that the electrical equipment storage room 4 or the maintenance equipment temporary storage room 5 Electrical equipment and maintenance equipment, as well as cranes, are protected from salt spray corrosion.
[0027] Further improvement: One or more electrical equipment storage rooms 2 can also be directly built on the foundation platform 1 of the offshore wind turbine jacket, which can be used for the storage of electrical equipment or maintenance settings.
[0028] Further improvement: between rest room and electrical equipment storage room 4 and/or maintenance equipment temporary storage room 5, between each electrical equipment storage room 4 and maintenance equipment temporary storage room 5, and electrical equipment storage room 4 And/or between the temporary storage room 5 of maintenance equipment and the tower tube 8 on the foundation platform of the offshore wind turbine jacket, air exchange ports 9 are provided. Circulation, effectively ensuring the heat dissipation in each space.
[0029] The above-mentioned implementation examples are preferred implementation examples of the present invention, but the embodiments of the present invention are not limited by the above-mentioned implementation examples, and any other changes, decorations, substitutions, combinations or simplifications that do not deviate from the spirit and principles of the present invention All should be equivalent replacement methods, and all are included in the protection scope of the present invention.
