Three-degree-of-freedom wave energy float power generation device and power generation method

Abstract

The invention discloses a three-degree-of-freedom wave energy float power generation device and power generation method. According to the three-degree-of-freedom wave energy float power generation device, three power generation units are arranged corresponding to heaving, surging and rolling degrees of freedom, reciprocating wave energy on the degrees of freedom can be captured and is converted into unidirectional output of a generator through the power generation units, parallel connection of the plurality of degrees of freedom and overlay utilization of corresponding energy are achieved, andrelatively high benefits are achieved; and resonance springs are arranged at the two ends of horizontal rods and vertical motion rods, collision impact force can be reduced, return motion of a floatis facilitated, and motion of the float in directions of the degrees of freedom is more continuous due to a simple harmonic motion effect under the action of intermittent waves.

Description

Technical field [0001] The invention belongs to the field of wave energy power generation, and particularly relates to a three-degree-of-freedom wave energy floater power generation device and a power generation method in the field. Background technique [0002] With the depletion of petroleum and other petrochemical energy sources and the global concern about climate change caused by greenhouse gas emissions, low-carbon, energy-saving, and development and utilization of renewable energy are becoming the theme of world energy development. As a new type of clean and pollution-free renewable energy, ocean wave energy has become the focus of new research due to its large reserves, high energy density, wide distribution, and easy energy conversion. At present, most of the domestic wave energy float power generation devices are single-degree-of-freedom power generation, and there is less involvement in the capture of the movement of the float in the horizontal direction and the energy...

AI Technical Summary

Problems solved by technology

At present, most of the domestic wave energy float power generation devices are single-degree-of-freedom power generation, and the movement of the float in the horizontal direction and the capture of energy around a fixed axis are less involved, and the research and application of multi-degree-of-freedom motion coupling is even less
