AI Technical Summary

Technical Problem

Traditional anti-roll devices are difficult to apply to offshore wind power floating devices, limiting their development in deep-sea areas, and power supply is limited during long-distance transportation.

Method used

Design a grid-based roll reduction structure for a floating offshore wind turbine foundation. By fixing multiple rectangular frame grid arrays to the ship's side and stern, and combining them with an adjustable generator and electromagnetic management system, wave energy is converted into electrical energy to reduce sway and achieve active roll reduction.

Benefits of technology

It effectively reduces the swaying response of floating devices under wind and waves, increases the possibility of long-distance transportation, and adjusts the damping effect through an electromagnetic management system, making it suitable for floating devices of different sizes.

Abstract

The application discloses a grid stabilizing structure of offshore wind power cylinder type foundation floating device, which comprises an offshore wind power cylinder type foundation floating device and a plurality of grid array structures fixed on the ship side, the grid array is assembled by a grid plate with holes, an internal built-in excitation generator converts kinetic energy of water level change into electric energy, and a solar panel is arranged at the upper top cover. When the water level changes, an electromagnetic management system adjusts the excitation size of the excitation generator according to the motion response of the floating device, and at the same time, the motion response of the floating device is reduced, and electric energy is efficiently generated. The electric energy generated by the solar panel and the excitation generator is stored and used for power consumption of the floating device after rectification. The structure effectively reduces the motion response of the floating device under the action of wind and wave, and greatly improves the possibility of the floating device going to the deep sea.
