The utility model relates to an utilize wireless power supply device of pipeline rivers electricity generation, because have the miniature hydroelectric generator of setting on the supply channel, thealternating current power supply that this miniature hydroelectric generator produced is behind rectification filter component rectifying and wave -filtering, the subassembly charges to storage battery through charging, the direct current that flows through storage battery converts the alternating current into through the converter again, the transmitting coil that this alternating current passesthrough magnetic coupling resonant mode wireless power transfer unit produces alternating magnetic field, reception coil is the electric energy with relaying alternating magnetic field's energy conversion, thereby provide renewable energy and realized the wireless transmission of electric energy for the consumer. It is extravagant that this has not only reduced the energy, and the wireless transmission of electric energy has also solved water ferroelectric phase and has met the potential safety hazard problem that exists moreover.
