The invention relates to a piezoelectric wave energy generator, and belongs to the technical field of new energy. The inner wall of the machine body is a prismatic surface formed by a plurality of wall surfaces, and each wall surface is provided with a seat plate; a pendulum shaft is composed of a shaft head, a prism and a transmission wheel, and the prism is a regular polygon prism; the machine cover is arranged on a port of the machine body, a group of pendulum shafts are uniformly distributed in the machine body in the circumferential direction, and shaft heads are arranged in bearing holes in the left wall of the machine body and the machine cover; the transmission wheels on the pendulum shafts are in contact with one another in sequence in the circumferential direction; one pendulum shaft is provided with an inertia arm; an inertia block is arranged on the inertia arm and is adjustable in position; the two sides of the inertia arm are connected with the inner wall of the machine body through springs, the springs are perpendicular to the inertia arm, and the installation positions of the springs on the inertia arm are adjustable. One end of a piezoelectric vibrator is arranged on a machine body seat plate, and the other end of the piezoelectric vibrator abuts against the prism of the pendulum shaft; when sea waves fluctuate and make the machine body shake, the inertia block forces the pendulum shafts to swing through the inertia arm, the prism forces the piezoelectric vibrator to generate bending deformation and generate power, and electric energy is stored or output after being converted and processed.
Description
technical field [0001] The invention belongs to the technical field of new energy, and in particular relates to a piezoelectric wave energy generator. Background technique [0002] In order to meet the power supply requirements of micro-power electronic products, remote sensing and embedded monitoring systems, etc., and to avoid environmental pollution by a large number of discarded batteries, research on micro-miniature generators or energy harvesters based on the principles of electromagnetic, friction and piezoelectricity has become a domestic Outside hotspots. There are many patent applications at home and abroad in the construction of micro-generators using various principles. The energy sources involve multiple aspects such as vibration energy, fluid energy, rotational kinetic energy and human motion energy in the environment. Relatively speaking, the driving force of wave energy exists widely and has high energy density, so it has more potential for development and a...
