Multi-degree-of-freedom eccentric swing type wave power generation device and method

Abstract

The invention discloses a multi-degree-of-freedom eccentric swing type wave power generation device and method. The multi-degree-of-freedom eccentric swing type wave power generation device comprisesan arc-shaped shell. An upper outer ring is mounted at the top of the arc-shaped shell, a top cover is mounted at the top of the upper outer ring, a lower base in the horizontal direction is mounted at the bottom of the arc-shaped shell, a gear frame is mounted on the lower base, and a generator, a driven shaft and a gear shaft are mounted on the gear frame in the vertical direction. An output shaft of the generator is connected with a bearing mounted on the lower base, and a generator gear capable of driving the generator to rotate is mounted on the output shaft of the generator. The arc-shaped shell of the power generation device is of a symmetrical structure, and the power generation device can capture wave energy of incoming waves in all directions, is not limited by wave directions, and is suitable for using in a random wave environment. According to the power generation method and the power generation device used by the same, gear commutation is adopted to convert the bidirectional swing of a swing arm into the unidirectional rotation of the generator without installing a plurality of generators, so that the structure is simplified, the size is reduced, the movement synchronization rate of different output ends is ensured, and the electrical power output is more stable.

Description

technical field [0001] The invention belongs to the field of wave energy generating devices, in particular to a multi-degree-of-freedom eccentric pendulum type wave energy generating device and a generating method in the field. Background technique [0002] In today's world, traditional fossil energy sources such as coal, oil, and natural gas are decreasing day by day, which has led to rising energy prices and an energy crisis is approaching. At the same time, the environmental pollution caused by the combustion of fossil energy seriously threatens all living things on the earth, including human beings. Ocean energy, as a kind of renewable energy with abundant reserves, clean and environment-friendly, has attracted great attention of people. In the ocean, wave energy is the most widely distributed and has extremely rich reserves. Compared with other types of ocean energy resources, wave energy resources have a high energy flow density and can be obtained in both nearshore a...

Problems solved by technology

However, in order to utilize the wave energy in all directions, the existing pendulum wave energy power generation device needs to install multiple power sources, resulting in complex structure and large volume of the device, and it is impossible to guarantee the synchronization rate of motion at different output ends.
