Embodiment Construction

[0026] Such as figure 1 As shown, this embodiment includes four regularly arranged steel piles 4 (the number is determined according to the stress conditions), a jacket 8 fixedly installed above the steel piles 4, and an upper equipment group of the booster station installed on the jacket 8 Piece. The four steel piles 4 are all arranged vertically (or slightly inclined), and their lower ends are deep into the bearing layer below the seabed, and the projection of each steel pile 4 on the horizontal plane is the four vertices of a square. The bottom end of the jacket 8 is fixedly connected to the steel pile 4 through the pile sleeve 3, and the top is equipped with a hoisting mechanism 2 for hoisting the upper equipment block of the booster station to a set position, and then installing it on the jacket 8 (In this example, a buckle is reserved on the upper part of the jacket to connect the upper equipment block). Electrical, fire-fighting and HVAC equipment are arranged in the up...

Abstract

The invention relates to a self-installation type offshore booster station structure which is safe and high in efficiency, saves cost and has low requirements on ship machine equipment. The technical scheme is that the self-installation type offshore booster station structure comprises at least four steel piles which are vertically and regularly arranged, a guide pipe support fixedly installed above the steel piles and a booster station upper equipment assembly block installed on the guide pipe support, wherein the lower ends of the steel piles stretch deep into a supporting layer under a sea bed. The booster station structure is characterized in that a hoisting mechanism used for hoisting the upper equipment assembly block is arranged at the top end of the guide pipe support. The upper equipment assembly block is defined into an annular shape in splicing mode through a branch assembly block I and a branch assembly block II and is coaxially fixedly sleeved on the periphery of the guide pipe support. The structure is suitable for the field of ocean engineering like offshore wind power generation.

Description

Technical field [0001] The invention relates to a structure of a sea booster station and an installation method thereof, and is mainly applicable to the field of marine engineering such as offshore wind power generation. Background technique [0002] In my country, offshore wind power generation is an emerging industry. After 2007, my country began to gradually develop the offshore wind power industry. my country's offshore wind power industry is still in its infancy. At present, the domestic offshore wind farms that have been built send the electricity generated by wind turbines to the land, and the land booster station is boosted and then sent to the grid. With the development of offshore wind power generation technology in China, offshore wind farms are getting farther and farther away from shore, and the scale of wind farms is getting larger and larger. The traditional way of setting up land booster stations on land is due to the large loss of low-voltage transmission lines a...
