Novel bionic ice-resistant wave-absorbing device of semi-submersible floating fan foundation structure
The invention belongs to the technical field of ocean engineering equipment, and discloses a novel bionic ice-resistant wave absorbing device of a semi-submersible floating fan foundation structure. Based on a bionic concept and an energy consumption principle, the novel ice-resistant vibration-damping wave-absorbing device with excellent performance is designed. The semi-submersible floating foundation structure comprises a semi-submersible floating foundation structure steel pile, a monitoring control system, a hydraulic driving system and a bionic ice-resistant wave-absorbing structure system. In the ice containing period, the upper conical face of the bionic ice-resistant wave-absorbing structure system makes contact with sea ice, the sea ice is induced to be bent and damaged, and heat energy generated by the friction resistance eliminating effect facilitates ice resistance; in the ice-free period, the vertical concave-convex face of the bionic ice-resistant structure makes contact with waves, and the waves are absorbed. And the natural vibration frequency of the offshore wind turbine can be adjusted, so that resonance damage is prevented. In conclusion, the method is suitable for wind power plant areas in high-latitude sea areas in China, reliable technical support is provided for ice resistance and wave absorption of the semi-submersible floating type draught fan, and safety and stability of the semi-submersible floating type draught fan foundation are maintained all weather.
