Abstract

The invention discloses a nano friction wind energy generator with a grass structure, comprising: the number of generators formed by elastic plastic sheets with a number n of units fixed on a base is n-1 (n is the number of edge units) nano-structure of the grass structure. The generator, in which the front and back sides of each elastic plastic sheet are respectively made of materials with large difference in friction polarity sequence, which act as contact electrodes and back electrodes, and each elastic plastic sheet is staggered in the order of friction polarity sequence; Under this condition, the friction polarities of all the unit generators are greatly different in surface contact and separation, and thus there is a pulsed electrical signal output. The generator of the present invention can convert the wind energy formed by nature, highways, tunnels, etc. into electric energy.

Description

technical field [0001] The invention relates to an electric generator, in particular to a grass-structured nanometer friction electric generator which converts mechanical energy generated by wind energy into electric energy. Background technique [0002] As one of the most important renewable energy sources in nature, wind energy is caused by solar radiation heat. The sun radiates to the earth's surface, and the different parts of the earth's surface are heated differently, resulting in temperature differences, which cause the convective movement of the atmosphere to form wind. It is estimated that although only about 2% of the solar energy reaching the earth is converted into wind energy, the total amount is still considerable. Global wind energy is about 2.74×l0 9 MW, of which the available wind energy is 2.74×l0 7 MW is 10 times larger than the total amount of water energy that can be developed and utilized on the earth. However, due to the high price, relatively larg...
