The invention relates to a marine floating platform seabed anchoring and fixing device having a fractal characteristic. The marine floating platform seabed anchoring and fixing device comprises a benthonic anchor fixing part and a mooring part for connecting a platform and the anchor fixing part, wherein the anchor fixing part is of a fractal tree structure provided with a plurality of layers, a plurality of tree-like structure forks are arranged at the top ends of the trunk of the fractal tree, and the adjacent tree-like structure forks having parent child relation have self-similarity iteration relation of a geometrical shape. According to the marine floating platform seabed anchoring and fixing device having the fractal characteristic, the fractal tree structure based on a fractal theoretical construction is applied to a benthonic anchor fixing device of a floating wind turbine. The fixing anchor and seabed contact area is increased by adopting the multi-layer branch structure of a fixing anchor, so that a fixing effect of the device is good. In addition, the pull force in the vertical direction can be borne by adopting the fixing anchor with the fractal tree structure, and the pull force in the horizontal direction can be also borne.
Description
technical field [0001] The invention relates to a mooring fixing device, in particular to a seabed mooring fixing device of an offshore floating platform. Background technique [0002] With the development trend of wind turbines from land to sea, from small to large, and from fixed to floating, offshore floating wind turbines have attracted the attention of many researchers. Offshore floating wind turbines mainly include wind turbines, towers, floating devices, and anchor mooring systems. The floating device of the offshore wind turbine is a floating platform. The main structural forms of the floating platform include: tension leg type, semi-submersible type and single column type. The methods of stabilizing the floating platform of wind turbines are: ballast type, anchor mooring line type and buoyancy type. Because offshore floating wind turbines are subjected to the comprehensive effects of wind current and seawater wave current loads, the stability of floating platforms...
