All carbon brush assemblies 2302 are connected to the same electric energy storage device through wires, and each carbon brush assembly 2302 can also be connected to a corresponding electric energy storage device through wires, or each electric energy storage device is connected to multiple carbon brush assemblies 2302); in daily working conditions, under the action of wind force, the first upper combined blade 303 and the first lower combined blade 304 of the first power generation mechanism 3 drive the outer rotor and the inner rotor of the first power generation mechanism 3 to rotate in opposite directions, and the collector ring assembly 23 corresponding to the first power generation mechanism 3 generates the first power generation mechanism 3 The electric energy generated is collected; the second upper combined blade 402 and the second lower combined blade 403 of the second power generation mechanism 4 drive the outer rotor and the inner rotor of the second power generation mechanism 4 to rotate in opposite directions, and the collector ring assembly 23 corresponding to the second power generation mechanism 4 collects the electric energy generated by the second power generation mechanism 4; finally, all the generated electric energy is transmitted to the electric energy storage device for storage; since the inner and outer rotors of the first power generation mechanism 3 and the second power generation mechanism 4 in the utility model rotate in opposite directions, the output power is increased by more than two times compared with the traditional generator in which only one of the stator and the rotor rotates; and since the first thrust bearing 7, the second thrust bearing 9, the third thrust bearing 17, and the fourth thrust bearing 20 are set, the first power generation mechanism 3 and the second power generation mechanism 4 can be effectively prevented from being eccentric during the rotation process driven by wind, and the operation stability of the first power generation mechanism 3 and the second power generation mechanism 4 is effectively guaranteed, thereby further improving the output power of the first power generation mechanism 3 and the second power generation mechanism 4, and the output power can be increased by more than three times compared with the traditional generator in which only one of the stator and the rotor rotates.
