The invention relates to the electric generator technology field and discloses a frictional electric generator used for collecting fluid flow energy. The frictional electric generator comprises a first friction electricity generation unit (1), a second friction electricity generation unit (2) and a fixing unit (3), wherein the second friction electricity generation unit (2) is arranged correspondingly to the first friction electricity generation unit and is used for carrying out elastic vibration when the fluid flows through; during a vibration process, the second friction electricity generation unit is contacted with or separated with the first friction electricity generation unit (1); during contact and separation processes, the first friction electricity generation unit and the second friction electricity generation unit generate a friction electric potential difference; and the fixing unit (3) is used for fixing two ends of the second friction electricity generation unit (2) to the first friction electricity generation unit (1) so that the second friction electricity generation unit (2) and the first friction electricity generation unit (1) have a set gap when the second friction electricity generation unit (2) is static. The frictional electric generator used for collecting the fluid flow energy can provide high-frequency electric signal output.
Description
technical field [0001] The invention relates to the technical field of generators, in particular to a friction generator for collecting fluid flow energy. Background technique [0002] In recent years, the in-depth research on tribogenerators based on triboelectrification and electrostatic induction has also made great progress in tribogenerators that harvest fluid flow such as wind energy. But the current application is mainly concentrated in the low frequency stage, and the output signal of the generator is generally lower than 2000Hz. These low-frequency friction generators generally have the characteristics of high output voltage and low output current. It is necessary to design a management circuit for voltage transformation and conversion, and a lot of energy will inevitably be lost during the conversion process. Therefore, how to directly obtain high-frequency electrical signals is an urgent problem to be solved in the design of friction generators. Contents of the...
