The invention relates to the electric generator technology field and discloses a compound electric generator used for collecting fluid flow energy. The electric generator is arranged in a fluid space (5). The electric generator comprises a first friction electricity generation unit (1), a second friction electricity generation unit (2) and a magnetoelectric electricity generation unit, wherein the first friction electricity generation unit (1) is arranged on an upper side of the fluid space and / or an inner wall (51) of a lower side; 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; during contact and separation processes, the first friction electricity generation unit and the second friction electricity generation unit generate a friction electric potential difference; the magnetoelectric electricity generation unit comprises a magnet (41) and a coil (42); during a second friction electricity generation unit vibration process, the magnet and the coil generate relative motion so that the electric potential difference is induced in the coil. In the invention, through combining the friction electricity generation units and the magnetoelectric electricity generation unit, conversion efficiency of energy and output power can be increased.
Description
technical field [0001] The invention relates to the technical field of generators, in particular to a compound generator for collecting fluid energy. Background technique [0002] With the depletion of traditional fossil fuels, energy issues have become a shackle restricting the development of human society. Researchers at home and abroad have turned their attention to renewable new energy sources. Among them, the nanogenerator proposed to solve the problem of energy supply for micro-nano devices and systems has increasingly become the leader leading the development of micro-nano energy. [0003] There have been many reports on nanogenerators based on piezoelectric effect, pyroelectric effect, friction effect, and magnetoelectric effect. Chinese patent "Wind power generation device and system based on friction generator" (CN 203445807U), Chinese patent "A wind power friction nanogenerator" (CN 103780128A), Chinese patent "Wind power generation device based on high frequency...
