A passive wave-absorbing and anti-rolling power generation device for a floating wind turbine platform

Abstract

The invention provides a passive wave absorbing and anti-sway power generation device of a floating fan platform, which comprises a floating fan platform, a wave absorbing float, a buffer spring and a linear generator. The floating fan platform includes platform legs and struts, and the linear power generation The machine includes a stator and a mover. The invention can reduce the motion response of the floating fan under the action of waves, and can also absorb the wave energy and convert the wave energy into electric energy. The buffer spring and linear generator can play a role of anti-sway, increase the motion damping of the floating fan platform, and reduce the motion response of the floating fan platform under the action of waves; the wave absorbing float absorbs the wave energy and converts the wave energy into The mechanical energy of its movement and the mechanical energy of the wave absorbing float are converted into electrical energy through the linear generator. The invention can effectively reduce the motion response of the floating fan platform under waves, so that the fan can be in a more stable working state, and the working efficiency and safety of the fan can be improved.

Description

technical field [0001] The invention relates to the development and utilization of wave energy and wind energy and the seakeeping of marine structures, in particular to a passive wave-absorbing and anti-rolling power generation device for a floating wind turbine platform, which belongs to the field of ships and ocean engineering. Background technique [0002] In the field of wind energy development and utilization, offshore wind energy not only has reserves, but also has higher wind energy density, which is more conducive to development and utilization. At present, in the development and utilization of wind energy, the technology of onshore wind turbines is quite mature, but there are still many important problems to be solved in the technology of offshore wind turbines. Offshore wind turbines are divided into two types: fixed wind turbines and floating wind turbines. The fixed wind turbines are suitable for sea areas where the water depth is not too deep. Because their pile...

AI Technical Summary

Problems solved by technology

Offshore wind turbines are divided into two types: fixed wind turbines and floating wind turbines. The fixed wind turbines are suitable for sea areas where the water depth is not too deep. Because their pile foundations are fixed on the seabed, they are similar to land-based wind turbines. Currently, there are not many technologies in application. However, there are many technical challenges in the application of floating wind turbines, which is also the main reason for the slow development and utilization of offshore wind energy.
