Embodiment 1

[0033] like Figure 1 to Figure 3 As shown, a device for improving wave power generation efficiency includes a wave energy concentrating device 10 and a wave energy collecting and converting device 11 . The wave energy concentrating device 10 is composed of five half-sine crest cylinders 1 arranged periodically, the wavelength of the wave crest cylinder 1 is half the wavelength of the regular incident water wave, and the periodic undulation extension direction of the wave energy concentrating device 10 is consistent with the direction of the incident wave. The distance between every two crest cylinders 1 is half of the wavelength of the wave crest cylinders 1, and the incident wave passes through the wave energy concentrating device 10 and is reflected by Bragg resonance, forming a standing wave region on the wave-facing side. The wave energy collection and conversion device 11 includes a fixed bracket 2, a metal panel 4, a stator 5 of a wave energy generator, a metal connecti...

Abstract

The invention discloses a device for improving efficiency of wave power generation and a manufacture method of the device. The device comprises a wave energy gathering device and a wave energy collecting and transforming device, wherein the wave energy gathering device comprises a plurality of wave crest cylinders arrayed according to periodicity, an incident wave is reflected because Bragg resonance occurs through the wave energy gathering device, and a vertical wave region is formed on a head wave side of the wave energy gathering device; the wave energy collecting and transforming device comprises a fixed bracket, a metal panel and a wave energy power generating device, wherein the fixed bracket is arranged in the vertical wave region, the metal panel is welded to the fixed bracket, and the wave energy power generating device is movably arranged on the metal panel. According to the device for improving the efficiency of the wave power generation and the manufacture method of the device, the position of the wave energy power generating device is fixed through a fixed platform, the periodic wave crest cylinders are arranged, and the Bragg resonance occurs to the incident wave so as to gather wave energy in a specific region, so that the power generating efficiency of the wave energy power generating device is improved.

Description

technical field [0001] The invention relates to the technical field of developing and utilizing marine renewable energy, in particular to a device for improving wave power generation efficiency based on the Bragg resonance principle and a manufacturing method thereof. Background technique [0002] The ocean covers 70% of the earth's surface and contains infinite energy. It is estimated that the sum of its energy greatly exceeds the current global energy demand. In the field of ocean energy development technology, there are wave energy, tidal energy, temperature difference energy, salinity difference energy and ocean current energy. [0003] Wave energy refers to the kinetic and potential energy of ocean surface waves. At this stage, there are a large number of technologies that utilize wave energy to generate electricity. The main principle is to convert wave energy into mechanical energy and then into electrical energy through wave energy devices. However, wave energy is ...
