Description

Technical Field

[0001] The present invention relates to an offshore booster station, and particularly to a fixing fixture for a prefabricated cabin of an offshore booster station and an offshore booster station. Background Art

[0002] With the continuous development and progress of economy and civilization, the world is in an environment of vigorously developing low-carbon economy. How to develop efficient, clean and renewable new energy has become a common problem for all countries in the world. Wind energy is one of the renewable energy sources that have attracted great attention from all countries in the world due to its large volume and pollution-free characteristics. In the past few decades, the global wind power installed capacity growth rate has reached 28%, making it the "main force" in renewable energy power generation. The global ocean area is vast, accounting for about 70% of the global area, and the offshore wind energy resources are about three times that of onshore wind energy resources, with rich resource reserves and development prospects.

[0003] An offshore wind farm mainly includes two core modules, one is a wind turbine, and the other is an offshore booster station. As the heart of an offshore wind farm, the offshore booster station is the core of the project technically and has functions such as power collection, boosting, and transmission. Compared with a conventional offshore booster station, the prefabricated cabin type offshore booster station can reduce steel structures such as secondary beams and diagonal braces by combining modular prefabricated cabins with the main structure, reduce the weight of the upper module of the offshore booster station. At the same time, splitting an integral booster station into several split structures expands the number of working surfaces for structural construction and equipment installation, and can effectively shorten the total design construction period. Therefore, the modular prefabricated cabin type offshore booster station will be the future development trend of offshore booster stations.

[0004] At present, the prefabricated cabin in the prefabricated cabin type offshore booster station is connected to the main structure by welding, and there is no other fixing method. As the core of an offshore wind farm, the offshore booster station faces harsh marine environments, and its safety is crucial. Therefore, there is an urgent need for a fixing fixture for a prefabricated cabin of an offshore booster station. Summary of the Invention

The support plate is welded to the flange plate of the bottom beam of the prefabricated cabin. The bottom plate is tightly attached to the flange plate of the structural beam of the main structure and welded into one body. The base is welded to the fixing plate as a whole. The thickness of the bottom plate is the same as the thickness of the flange plate of the bottom beam, and the height of the pasting plate is less than the height of the web of the bottom beam.

[0016] Preferably, the bottom beam of the prefabricated cabin is square-shaped steel, and the structural beam of the main structure adopts H-shaped steel. The pasting plate is tightly attached to the side plate of the bottom beam of the prefabricated cabin and welded into one body. The bottom plate is tightly attached to the flange plate of the structural beam of the main structure and welded into one body. The base is welded to the fixing plate as a whole.
