The invention discloses an electromagnetic-friction nano water flow power generation device which comprises a casing, a rotor, a stator, a permanent magnet, a coil, a rotating shaft, a turbine and anexternal circuit. An electromagnetic power generator is formed by the casing, the coil, the permanent magnet and the rotating shaft. Two ends of the casing are equipped with two friction nanogenerators which comprise stators, rotors, Teflon films and copper electrode films, and the surfaces of the copper electrode films and the Teflon films are in contact with each other. Since the friction nano power generation technology is employed in the invention, a voltage of about 200V can be generated at a rotation speed of 10r / min, the output voltage of electromagnetic power generation is gained, andthe current outputted after the combination of the two can reach a milliampere level, which is sufficient for powering most sensor components. Since the friction nanogenerators and the electromagneticpower generator of the invention are connected through the same rotating shaft, the same angular velocity is ensured, and therefore, the output currents of the two power generation modes are in the same phase.
Description
technical field [0001] The invention relates to an energy collection device, in particular to an electromagnetic-friction nanometer water flow power generation device. Background technique [0002] With the rapid consumption of global energy, the development and utilization of new energy is particularly important for the development of society and the protection of the ecological environment. Triboelectric nanogenerators use the relative motion and interaction between nanomaterials to effectively collect low-frequency energy and convert it into electrical energy.
