A floating fan platform based on suspended vibration damping device

Abstract

The invention belongs to the field of ships and marine engineering, and provides a floating fan platform based on a suspension vibration damping device. The floating fan platform includes a wind turbine, a tower structure, a floating platform and a mooring system; the floating platform mainly It is composed of independently moving pontoons, upper double wishbone, lower double wishbone, spring damping device and platform center structure. The invention can enhance the motion performance of the floating platform, reduce the motion response of the floating fan under the action of wind and waves, reduce the mutual influence between the buoys, and reduce the impact of the floating fan platform on the tower under the action of waves. The sway of the tower can be reduced under the action of impact and turbulent wind. The invention can effectively reduce the overall motion response of the floating fan platform under waves, reduce the swing amplitude of the tower, and make the fan in a more stable working state, thereby improving the power generation efficiency and safety of the fan.

Description

technical field [0001] The invention relates to the field of ships and marine engineering, in particular to the development and utilization of marine wind energy and the sea resistance of marine structures, in particular to a floating fan platform based on a suspension vibration damping device. Background technique [0002] Wind energy is a kind of renewable and clean energy. my country's offshore wind energy reserves are huge. Offshore wind power at a water depth of 5m-50m and a height of 70m is expected to develop 500 million kilowatts of resources. However, as the water depth increases and the development of nearshore resources tends to be saturated, the disadvantage of the fixed foundation is obvious, and the floating foundation becomes the best choice. However, the development of floating wind turbines faces many technical challenges. Europe has carried out offshore floating prototype tests more than ten years ago, and has accumulated rich design experience, but there i...

Problems solved by technology

However, the development of floating wind turbines faces many technical challenges. Europe has carried out offshore floating prototype tests more than ten years ago, and has accumulated rich design experience, but there is still no large-scale production.

Floating wind turbines are fixed on the seabed by a mooring system. Under the action of wind and waves, the wind turbine platform moves within a certain range. Frequent and many other unfavorable factors aggravate the motion response of the platform and seriously affect the working efficiency and safety of the fan
