The invention provides a power generation pavement based on a rotary direct-current friction nano generator, which comprises an upper supporting part, a lower supporting part and the rotary direct-current friction nano generator arranged between the upper supporting part and the lower supporting part, the lower supporting part is located at a preset
fixed position, and the upper supporting part can move up and down; the upper supporting part is connected to a rotor of the rotary direct-current friction nanometer generator, the rotary direct-current friction nanometer generator comprises a supporting shell, a
stator and a rotor, the
stator and the rotor are arranged in the supporting shell, the
stator comprises a tolerance compensation device and a friction
electrode fixed on the tolerance compensation device, the rotor is arranged in the center of the interior of the supporting shell, and a friction layer is attached to the rotor. An electrostatic breakdown
electrode is fixed above the rotor, a preset distance is arranged between the electrostatic breakdown
electrode and the friction layer, and the tolerance compensation device is used for enabling the friction layer to be in
close contact with the friction electrode, so that the rotor and the friction electrode keep the same coaxiality.
Kinetic energy of human walking treading actions is collected and converted into
electric energy, then power is supplied to urban sensors, and
energy conservation and
environmental protection are achieved.
