Abstract

The invention discloses a wave-energy piezoelectric power generation device based on fixed frequency and natural vibration. The wave-energy piezoelectric power generation device is characterized in that the wave-energy piezoelectric power generation device comprises a power generation device body (1) and a fixing device (2) used for fixing the power generation device body to the sea surface; the power generation device body comprises a spindle (3), the spindle (3) is provided with an upper water stop plate (4) and a lower water stop plate (5), and the upper water stop plate (4) and the lower water stop plate (5) penetrate the spindle (3) and are fixed to the spindle (3) through an upper fixing bearing (6) and a lower fixing bearing (7) respectively. The wave-energy piezoelectric power generation device has the advantages of capability of achieving fixed-frequency conversion of wave energy simply and effectively, remarkable environmental and economic benefits, simple structure, low cost, capability of being produced massively and capability of being widely applied to the wave energy power generation industry and the production field of products such as beacon lights to realize commercial development.

Description

technical field [0001] The invention relates to a wave energy piezoelectric power generation device based on fixed-frequency self-vibration, which belongs to the technical field of new energy sources. Background technique [0002] With the depletion of traditional energy and the increasingly fragile ecological environment, as well as the worldwide requirements for energy conservation and emission reduction, the development and utilization of clean new energy has become one of the most important frontier topics for mankind today. The wave energy with large reserves, wide distribution, low degree of utilization, and cleanness has become one of the focuses of new energy development and utilization. [0003] One of the most important limiting factors for wave energy to be fully utilized is its mixing characteristics. Waves are not a single frequency, but a mixture of waves of different frequencies. The frequency of waves in the eastern coastal areas of my country is between 0....
