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 lan

Embodiment Construction

[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0014] combine Figure 1-3 , the present invention includes a floating fan platform, a wave-absorbing buoy ①, a buffer spring ③, and a linear generator. The floating fan platform includes platform legs ② and struts ⑥, and the linear generator includes a stator ④ and a mover ⑤. Floating wind turbine platform is a general term, and this device can also be used for other marine structures such as offshore platforms.

[0015] The wave-absorbing float ① mainly has two functions, one is to provide the buoyancy required by the fan platform, and the other is to absorb wave energy and convert the wave energy into mechanical energy of its own motion; the buffer spring ③ acts as a motion buffer to increase the motion damping of the fan platform The fan platform is used to support the fan, including the platform legs ② and the struts ⑥; the line...

Abstract

The invention provides a passive wave absorbing and roll damping power generation device of a floating draught fan platform. The passive wave absorbing and roll damping power generation device comprises the floating draught fan platform, wave absorbing floaters, buffer springs and linear generators. The floating draught fan platform comprises platform pile legs and brace rods. Each linear generator comprises a stator and a rotor. The passive wave absorbing and roll damping power generation device can reduce motion response of floating draught fans under the wave action and can also absorb wave energy and convert wave energy into electric energy. The buffer springs and the linear generators can play a role of roll damping, increase motion damping of the floating draught fan platform and can reduce motion response of the floating draught fan platform under the wave action. The wave absorbing floaters absorb wave energy and convert wave energy into motion mechanical energy of the wave absorbing floaters. The motion mechanical energy of the wave absorbing floaters can be converted into electric energy through the linear generators. The passive wave absorbing and roll damping power generation device can effectively reduce the motion response of the floating draught fan platform under waves, enable the draught fans to be in a more stable operating state and improve the working efficiency and safety of the draught fans.

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...
