Novel energy drawing-shock absorbing deep sea wind power generating floating type semi-submersible platform

Abstract

The invention relates to the field of offshore wind power generation, in particular to a novel energy drawing-shock absorbing deep sea wind power generating floating type semi-submersible platform. The novel energy drawing-shock absorbing deep sea wind power generating floating type semi-submersible platform comprises a draught fan blade, a draught fan, a tower barrel and a semi-submersible platform body; the semi-submersible platform body comprises three floating barrels and a triangular floating box; and a wave energy drawing-shock absorbing system is installed in the floating barrels and comprises a power generator, an inertia container, a return spring and a plurality of bearing springs. According to the semi-submersible platform, according to the sea condition or the actual requirement, by adjusting the load power of the power generator and the hydraulic oil flowing speed of the inertia container, influences on normal running of an upper draught fan by the vertical swinging, transverse rocking and longitudinal rocking freedom degree wave frequency response caused by wave loads and the problems of fatigue damage and the like are inhibited, and meanwhile, wave energy is converted into electric energy; and the energy drawing-shock absorbing system serves as a passive control system and fully utilizes the platform stand column space, the shock absorbing performance of the system is reliable, meanwhile, wind power generating and wave energy power generating are integrated, and the whole system has good economical efficiency.

Description

technical field [0001] The invention relates to the field of offshore wind power generation, in particular to a novel energy-absorbing-vibration-reduction deep-sea wind power generation floating semi-submersible platform. Background technique [0002] At present, the structural forms of offshore wind power generation equipment can be divided into two types: floating type and fixed type. When the water depth is greater than 50 meters, the floating wind power platform has become one of the main equipment for deep-sea wind power generation because of its economic efficiency is better than that of the fixed structure. The offshore floating wind turbine will generate strong vibration under the action of wind load and wave load. If the vibration is not controlled during the entire service period, it will not only affect the stability of the wind turbine operation, but also easily cause fatigue damage to the floating foundation. Wave energy and wind energy are both important clean...
