Description

technical field [0001] The present invention relates to the technical field of wind power generation, in particular to a wind power generation device based on a dielectric elastomer. Background technique [0002] Under the multiple factors such as the intensification of global warming and the pressure of energy transition, the development of new green energy has become a common goal of the world. Among the new energy sources, wind energy has attracted more and more attention due to its huge reserves, wide distribution, non-polluting and renewable characteristics, and the use of wind energy for power generation has become the general trend. [0003] The initial wind power generation was based on the principle of electromagnetic induction. In recent years, the use of piezoelectric ceramics, rubber and other new materials for wind power generation has become a research hotspot. Among the many materials that can generate electricity, dielectric elastomers (typically represented...

AI Technical Summary

Problems solved by technology

The existing cam mechanism makes the deformation of the dielectric elastic body small, and cannot fully utilize the advantages of the large deformation of the dielectric elastic body, reducing the energy conversion efficiency; the number of dielectric elastic bodies in the existing crank-link mechanism is small, and the space utilization is limited. The rate is not high, which reduces the power generation efficiency
