Abstract

The invention discloses a multi-section bent beam piezoelectric generator and a wave power generation ship. The piezoelectric generator comprises left and right fixed substrates arranged horizontallyopposite to each other. A plurality of piezoelectric elements are arranged in a linear array between the left and right fixed substrates. Each piezoelectric element comprises an energy obtaining component and an excitation component, wherein the energy obtaining component comprises piezoelectric coupling beams with one end fixedly connected with the left and right fixed substrates respectively, and the piezoelectric coupling beams are arranged in a tortuous manner, and a piezoelectric patch is adhered to the vertical beam surface of each piezoelectric coupling beam; and the excitation component includes an excitation ball arranged between the left and right piezoelectric coupling beams opposite to each other, and two ends of the excitation ball are fixed to or hinged with the left and right piezoelectric coupling beams respectively through a connecting member. The excitation ball drives connecting ends of the left and right piezoelectric coupling beams to vibrate up and down relative to fixed ends of the piezoelectric coupling beams to cause deformation of vertical beams of the piezoelectric coupling beams, and then the piezoelectric patches on the vertical beams are driven to be synchronously deformed to generate electric currents.

Description

technical field [0001] The invention relates to a generator, in particular to a multi-section bent beam piezoelectric generator and a wave power ship. Background technique [0002] In today's society, energy and environmental issues have become more and more concerned. The use of traditional energy has seriously threatened people's living environment. Therefore, the development and application of new energy has emerged as the times require. The so-called new energy refers to energy that has not yet been developed and utilized on a large scale. Its development technology is mainly renewable energy and clean energy developed and utilized on the basis of modern high technology, including the development of solar energy, geothermal energy, ocean energy and other energy. Nowadays, solar energy and geothermal energy are widely used, but they are greatly affected by the natural environment, and the ocean contains abundant energy, which has not been better developed and utilized.
