Abstract

The invention discloses an offshore wind generation set mounting foundation assembly. The offshore wind generation set mounting foundation assembly comprises a main pile, three or more auxiliary pilesand an auxiliary platform, the auxiliary piles take the main pile as the center and are evenly arranged around the main pile, the upper ends of the auxiliary piles extend out of the mud surface, andthe lower ends of the auxiliary piles extend to the position below the mud surface; the auxiliary platform is arranged at the mud surface and comprises a central connecting truss, the central connecting truss is provided with a plurality of sleeves, the multiple sleeves are fixedly connected with the main pile or the auxiliary piles, and connecting rods are arranged between the multiple sleeves. Through the technical scheme, the overall rigidity of the offshore wind generation set mounting foundation assembly can be improved, and in addition, by arranging an external truss and additionally loading filling materials in an internal area of the external truss, the scouring effect of a water flow on the mud surface near the main pile can be effectively reduced.

Description

technical field [0001] The invention relates to a basic building technology for offshore equipment installation, in particular to a basic component for installing offshore wind turbines. Background technique [0002] Wind power technology is relatively mature, and its cost is constantly falling. It has become the core content of energy transformation in many countries and an important way to deal with climate change. It is also an important means for my country to further promote the revolution of energy production and consumption and promote the prevention and control of air pollution. Offshore wind power has a broad market prospect in my country due to its advantages such as abundant wind energy resources, low noise restriction, and not occupying valuable land resources on land. [0003] The foundation forms of offshore wind turbines are various. At present, the foundation forms of wind turbines used at home and abroad mainly include gravity foundation, single pile foundat...
