Extensible multi-degree-of-freedom wave energy power generation device

Abstract

The invention discloses an extensible multi-degree-of-freedom wave energy power generation device. The extensible multi-degree-of-freedom wave energy power generation device comprises at least one motion unit, wherein each motion unit comprises a central buoy, an upper buoy, a connecting arm, a conversion mechanism and a power output module; the central buoy is hinged with one end of the connecting arm through the conversion mechanism; the upper buoy is hinged with the other end of the connecting arm through the conversion mechanism; and the power output module is arranged in the upper buoy. The extensible multi-degree-of-freedom wave energy power generation device can collect wave energy through motion of the device in multiple degrees of freedom, so that the wave energy is absorbed to the greatest extent, and the wave energy collecting efficiency and the wave conversion efficiency are improved; the device is high in extensibility; and a plurality of sets of devices are easy to form awave energy power generation field with ultrahigh flexibility and centralized maintenance, so that the reliability of the device is improved, the service life of the device is prolonged, and the maintenance and management difficulty and the economic cost of the device are reduced.

Description

technical field [0001] The invention relates to a device in the field of wave power generation, in particular to an expandable multi-degree-of-freedom wave power generation device. Background technique [0002] After the 21st century, with the continuous advancement of sustainable development, more and more countries are paying more attention to the development and utilization of marine energy. Various power generation systems, platforms and The research and development of the device came into being. At present, for the development and utilization of wave energy, there are many types of power generation devices. Due to the different mechanisms of device capture wave energy, the installation location and water depth conditions of the device are different, and the ways of converting wave energy into electrical energy are also various. According to the working principle of the device, wave power devices can be roughly divided into three categories, including oscillating water ...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is the problem that the wave energy generation device collects wave energy in one direction and one degree of freedom so that the efficiency of energy collection is not high, and when the wave energy generation device needs to be arranged in an array, the workload of the arrangement is large and centralized maintenance is required. Difficulty, low scalability and high cost
