Inertia wheel energy-storage friction nanogenerator of multi-sleeve structure based on differential transmission

Abstract

The invention relates to an inertia wheel energy-storage friction nanogenerator of a multi-sleeve structure based on differential transmission. The nanogenerator has the characteristic of efficientlycollecting random rotating mechanical energy in an environment, can achieve high-frequency power generation through a differential cylinder structure, and has long-time running capacity under single excitation. The nanogenerator comprises a supporting base I, a transmission assembly, an outer cylinder assembly, an inner cylinder assembly and a supporting base II. The inner cylinder assembly can rotate for a long time due to inertia, a friction material installed on the inner cylinder assembly and electrodes evenly distributed on the inner wall of the outer cylinder form a friction power generation unit; the continuous sweeping type friction is conducted along with reverse rotation of the outer cylinder assembly and the inner cylinder assembly, and electric energy is generated based on thecontact electrification principle and the electrostatic induction principle. Therefore, the nanogenerator can efficiently convert random irregular rotating mechanical motion energy into electric energy.
