Direct-current rotary friction nano power generation device with gear meshing structure

Abstract

The invention relates to a direct-current rotary friction nano power generation device with a gear meshing structure, which comprises a first gear assembly, a second gear assembly and a third gear assembly, and is characterized in that a first induction electrode is arranged on gear teeth of the first gear assembly, a first friction layer is arranged outside the first induction electrode, a secondfriction layer is arranged on gear teeth of the second gear assembly, a third induction electrode is arranged on gear teeth of the third gear assembly, and a third friction layer is arranged outsidethe third induction electrode; the second gear assembly rotates under the driving of a driving mechanism, so that contact friction is generated between the first friction layer and the second frictionlayer and between the second friction layer and the third friction layer, different charges are accumulated on the surfaces of different gear assemblies, a potential difference is generated between the first induction electrode of the first gear assembly and the third induction electrode of the third gear assembly, electrons are driven to flow in the same direction, and thus a direct current signal is output outwards. The direct-current rotary friction nano power generation device can output direct current without a rectifying circuit.

Description

technical field [0001] The invention relates to a friction nanometer power generation device, in particular to a gear meshing structure direct current rotation friction nanometer power generation device. Background technique [0002] In order to solve the energy crisis and environmental pollution, exploring the reuse of renewable energy is one of the great challenges facing mankind. At present, electromagnetic power generation equipment has become the mainstream device, but they have the disadvantages of bulky, heavy, and high construction costs.

Chinese patent application No. 201510232639.7 invented a rotary friction nanogenerator with a complex structure and an external output of alternating current, which must be rectified before use

The patent application number is 201310482286.7, which proposes a DC friction power generation device. The flow of electrons in the circuit needs to be realized by the phenomenon of discharge. There is a distance between the friction parts and the sensing electrodes, and the efficiency of electrostatic induction is low.
