The invention provides a rotary friction nanometer power generation device based on point discharge. The device comprises a discharge point, an upper stator, a rotor, a lower stator, a transmission rod, a fixed end face gear, a rotor end face gear and a spring, and is characterized in that the discharge point is arranged on the upper surface of the upper stator, and the rotor is arranged between the upper stator and the lower stator; the upper stator, the rotor and the lower stator are connected through a transmission rod, the fixed end face gear is arranged between the transmission rod and the upper stator, the rotor end face gear is arranged between the transmission rod and the rotor, the spring is arranged between the transmission rod and the lower stator, and the fixed transmission gear is fixedly connected with the transmission rod. The rotor end face gear is fixedly connected with the rotor and can slide on the transmission rod so that the rotor end face gear can move in the axial direction. According to the contact-separation process of a rotor electret and a stator dielectric friction structure, sliding friction can be reduced, friction resistance is reduced in the working process, abrasion of the dielectric friction structure is slowed down, and the durability of the structure is improved.

Description

Technical field [0001] The present invention belongs to the field of environmental energy acquisition technology, and more particularly to a rotary friction nano-generating device based on tip-discharge discharge. Background technique [0002] At present, the well-known rotary friction nano generator is mostly in contact with the radiostatic material film attached to the stator electrode on one rotor, and the electrostatic induction is generated in the two sets of electrodes on the stator, and then use the rotor to stand on the rotor. The electric field changes caused by extreme rotation, resulting in a variation of the potential difference between the two sets of stator electrodes, so that the electrons are driven back and forth between the two sets of electrodes to complete the charge transfer to achieve power generation. Since the residential surface charge density on the rotor will slowly decrease over time, the recurrent contact and friction of the eradices are required, and...

AI Technical Summary

Problems solved by technology

Since the surface charge density of the electret on the rotor will slowly decrease over time, frequent contact and friction between the electret and the dielectric friction material is required, and too frequent friction will reduce the durability of the device

In addition, since the surface charge density of the triboelectric nanogenerator is proportional to the square of its power output, the charge density obtained by the conventional contact electrification method is low, which greatly limits the energy conversion efficiency of the device.
