Abstract
A power generation system disclosed by the present invention comprises a power generating device and an energy storage device, and the power generating device comprises at least one nanometer friction generator used for transforming the mechanical energy into the electric energy, a shell for accepting the at least one nanometer friction generator, a rotating shaft, at least one cam and fan blades, wherein the at least one nanometer friction generator is fixedly arranged on the inner wall of the shell, a part of the rotating shaft is located outside the shell, and the other part of the rotating shaft extends into the shell; the at least one cam is fixedly arranged on the rotating shaft inside the shell, and the fan blades are fixedly arranged at the end part of the rotating shaft outside the shell. In the power generation system provided by the present invention, the nanometer friction generator is used as a core part of the power generating device utilizing the wind power generation to transform the wind energy into the electric energy, and the energy storage device can store the electric energy, thereby realizing the wind power generation.
Description
Technical field
The present invention relates to field of nanometer technology, more particularly, it relates to a kind of electricity generation system.
Background technology
In daily life, people are more typical method using wind-power electricity generation or solar electrical energy generation.Wherein, wind-power electricity generation
Principle be using wind-force drive air vane rotation, then by booster engine by rotate speed lifted promote generator send out
Electricity.According to current windmill technology, about three meters per second of gentle breeze speed（The degree of gentle breeze）, just can start to generate electricity.Wind
Power generates electricity and is just forming one upsurge in the world, because wind-power electricity generation need not use fuel, will not also produce radiation or air
Pollution.But, traditional wind-driven generator is bulky, with high costs, while during transport and installation, to user with
Great inconvenience is carried out.
Solar electrical energy generation mainly uses silicon photocell, and solar energy is directly changed into into electric energy, the method energy transformation ratio
Height, but application time scope is little, and evening or rainy weather can not be used.And when using wind turbine power generation, its time limitation
Property it is stronger, it is calm at many days in the case of cannot then carry out normal power generation so that affecting household electricity to stablize.Between above-mentioned feelings
Condition, combined using both solar electrical energy generation and wind-driven generator generate electricity then can complementary deficiency therein, but use simultaneously at present
When two kinds of equipment generate electricity, manual switching is needed, it is not only loaded down with trivial details but also do not reach good effect.
The content of the invention
The goal of the invention of the present invention is the defect for prior art, a kind of electricity generation system is proposed, to solve existing skill
In art wind-driven generator it is bulky, with high costs, transport and installation difficulty problem.
The invention provides a kind of electricity generation system, including：TRT and energy storage device；
The TRT includes：For mechanical energy being converted at least one nano friction generator of electric energy, being accommodated
The housing of at least one nano friction generator, rotary shaft, at least one cam and flabellum；Wherein, described at least one
Individual nano friction generator is installed on the inwall of the housing；A part for the rotary shaft is located at the hull outside, institute
The another part for stating rotary shaft extend into the enclosure interior；At least one cam is installed in positioned at the enclosure interior
In the rotary shaft；The flabellum is installed in the end of the rotary shaft positioned at the hull outside；
The energy storage device is connected with the output end of the nano friction generator, for the nano friction generator
The electric energy of output is stored.
