Wherein, first backup pad 1, second backup pad 2 parallel still are equipped with fixed axle 5 between first backup pad 1, the second backup pad 2, and both ends are fixed in first backup pad 1, second backup pad 2 respectively.
Specifically, the friction power generation mechanism 3 comprises a plurality of friction nano power generation units 4, the friction nano power generation units 4 are stacked, and the fixing shaft 5 penetrates through each friction nano power generation unit 4 to prevent each part of each friction nano power generation unit 4 from deviating.
Specifically, the friction nano-power generation unit 4 includes a first electrode layer 41, a dielectric film 42 and a second electrode layer 43 sequentially stacked in this order, in which the dielectric film 42 is made of PTFE, the first electrode layer 41 is a copper film, and the second electrode layer 43 is an aluminum film. Active friction occurs between the first electrode layer 41 and the dielectric film 42 under the influence of wind.
In order to improve the power generation efficiency, a nano-scale or sub-nano-scale microstructure is distributed on a part or the whole of the surface of the dielectric film 42. The microstructure is preferably a nanowire, a nanotube, a nanorod, a nanoparticle, a nano groove, a micro groove, a nano cone, a nanosphere, and an array formed by the aforementioned structures, particularly a nano array of nanowires, nanotubes or nanorods, and a linear, cubic or quadrangular pyramid-shaped array which can be prepared by photoetching, plasma etching, and the like, wherein the size of each unit in the array is in the micrometer to nanometer order, as long as the mechanical strength of the electrode film is not affected, and the size and shape of the unit of the specific microstructure should not limit the scope of the invention.

In the absence of wind, the first electrode layer 41 and the dielectric film 42 will not rub against each other. The number of the rubber elastic columns 44 of the elastic columns 44 of this embodiment is two, and the elastic columns 44 are uniformly and symmetrically distributed.
In addition, the friction nano-power generation unit 4 is electrically connected with a power management device, the power management device comprises a rectifier 6, a booster 7 and a battery 8, two ends of the rectifier 6 are respectively and electrically connected with a first electrode layer 41 and a second electrode layer 43 to form a loop, the input side of the booster 7 is connected with the output end of the rectifier 6, and the output side of the booster 7 is connected with the battery 8.

The implementation principle of the embodiment is as follows:
in the absence of wind, the first electrode layer 41 and the dielectric film 42 layer are not separated due to the spacing of the elastic columns 44. When wind blows, the friction nanometer power generation unit 4 of the friction power generation mechanism 3 generates vibration according to the principle of wind vibration, so that the rubber elastic column 44 is compressed and stretched, the first electrode layer 41 and the dielectric film 42 layer are frequently contacted and separated, and specifically, when the elastic column 44 is compressed and the first electrode layer 41 is contacted with the dielectric film 42, the first electrode layer 41 is positively charged and the dielectric film 42 is negatively charged due to the great difference of charge loss capacities of the two materials. When the elastic column 44 is stretched, the first electrode layer 41 is separated from the dielectric film 42, and at this time, electrons in the first electrode layer 41 enter the second electrode layer 43 through the connected external circuit, so that the positive charge of the second electrode layer 43 is less than that of the first electrode layer 41, and a potential difference is formed between the two electrode layers, so that current and voltage are formed in the external circuit, and the larger the separation distance is, the larger the generated voltage is. Until the first electrode layer 41 is completely separated from the dielectric film 42, at which point the voltage is maximized. The continuous wind provides enough energy to make each friction nano-power generation unit 4 continuously contact and separate, and when the friction nano-power generation unit contacts again, electrons flow back to the first electrode layer 41 from the second electrode layer 43 through an external circuit, so that continuous alternating current is generated. The power management device collects the generated alternating current and stores the amount of power in the battery 8.
