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 situation), the jacket 8 fixedly installed above the steel piles 4, and the upper equipment group of the booster station installed on the jacket 8 piece. The four steel piles 4 are arranged vertically (or slightly inclined), and their lower ends go deep into the bearing layer below the seabed, and the projection of each steel pile 4 on the horizontal plane is four vertices of a square. The bottom end of the jacket 8 is fixedly connected to the steel pile 4 through the pile casing 3, and the top end is provided with a hoisting mechanism 2, which is used to lift the upper equipment block of the booster station to the set position, and then install it on the jacket 8 (in this example, buckles are reserved on the upper part of the jacket to connect the upper equipment block). The upper equipment block of the booster station is equippe...

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 an offshore booster station and an installation method thereof, and is mainly applicable to marine engineering fields 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 electric energy generated by wind turbines to the land, and then send it to the power grid after being boosted by the land booster station. With the development of my country's offshore wind power generation technology, offshore wind farms are getting farther and farther offshore, and the scale of wind farms is getting bigger and bigger. The traditional way of setting up onshore booster stations on land is due to the large loss of low-vo...
