Problems solved by technology

However, this solution can only realize the absorption and conversion of wave energy in one dimension, that is, the wedge-shaped buoy can only generate power when it moves up and down, while the motion of the ocean wave is multi-dimensional, and energy conversion and power generation cannot be realized when the wedge-shaped buoy moves back and forth and left and right

Abstract

The invention provides a three-degree-of-freedom wave power generation device. The device comprises an up-down moving device, a front-back moving device, a left-right moving device, a floating part (18), an energy conversion device (7), a generator, a base (13) and a support (1), wherein the support (1) and the generator are arranged on the base (13); the up-down moving device, the front-back moving device and the left-right moving device are connected to the energy conversion device (7) and are mounted on the support (1); the energy conversion device (7) is connected to the generator througha pipeline (8); and the floating part (18) is correspondingly connected to the up-down moving device, the front-back moving device and the left-right moving device. The device is simple and reasonablein structure; wave energy in different dimensionality is correspondingly utilized by modular arrangement; the wave energy can be fully utilized to generate power; the power generation efficiency is high; and moreover, large-scale power generation can be realized.

Description

technical field [0001] The invention relates to the field of new energy, in particular to a three-degree-of-freedom wave energy power generation device. Background technique [0002] Wave energy is a relatively high-quality energy in ocean energy. Its research, development and utilization are of great strategic significance to achieve sustainable development and meet human energy needs. Current wave energy generating devices are basically in the research stage, and there are few wave energy generating devices in practical applications. [0003] The patent document with the publication number CN 108915940A discloses a wave energy generating device, which includes an active swing bar, a ratchet, an active pawl, a generator, and a wedge-shaped buoy. Its characteristic is that the wedge-shaped pontoon floats up and down with the waves to convert the wave energy into mechanical energy, and then transmit the mechanical energy to the generator through the ratchet structure to gene...
