Example Embodiment

[0025] Example 1:

[0026] Three custom-made nylon gear assemblies with the same shape and size, a diameter of 10 cm and a length of 15 cm were selected as the first gear assembly, the second gear assembly and the third gear assembly. For the materials of the first induction electrode and the third induction electrode, silver paste is selected to be uniformly coated on the tooth surfaces of the first gear assembly and the third gear assembly by brushing, and then dried with hot air. Polytetrafluoroethylene and polyurethane solutions were selected as the friction layer materials of the first gear assembly and the third gear assembly respectively, uniformly coated by spraying with a spray gun, and dried with hot air. The friction layer of the second gear assembly is the outer surface of its own nylon material. A cuboid made of plexiglass is used as a bracket to support the entire power generation device. Select a nylon blade to collect wind energy to provide the initial power ...

[0027] Example 2:

[0028]Three custom-made nylon gear assemblies with the same shape and size, a diameter of 10 cm and a length of 15 cm were selected as the first gear assembly, the second gear assembly and the third gear assembly. A cuboid made of plexiglass is used as a bracket to support the entire power generation device. For the material of the first induction electrode and the third induction electrode, a polythiophene conductive polymer is selected to be sprayed on the gear teeth of the first gear assembly and the third gear assembly by atomization. Polyvinyl chloride film and polyurethane film are selected as friction layer materials, and conductive adhesive is used to uniformly adhere them to the gear teeth of the first gear assembly and the third gear assembly respectively. The friction layer of the second gear assembly is the outer surface of its own nylon material. Under the action of wind energy, the nylon blade rotates, and the nylon friction surface, polyvin...

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. [0003] In 2012, the triboelectric nanogenerator proposed by Wang Zhonglin's research team can effectively collect various forms of mechanical energy, opening a new model. The Chinese patent application number is 201510232639.7, which invented a rotary friction nanogenerator, which has a complex structure and outputs alternating current, which must be rectified before use. The patent application number is 201310482286.7, which pr...
