Non-load wind power generation device

The invention provides a non-load wind power generation device. The non-load wind power generation device is composed of a magnetic ring set, a shaft rod, a rotary disc, fan blades and a fixing base.The magnetic ring set is provided with multiple magnetic ring columns, and a hole is formed in the middle for the shaft rod to penetrate through. A bearing is arranged in the center of the rotary disc, and multiple magnets are arranged on the inner side periphery. During assembly, after the shaft rod penetrates through the hole of the magnetic ring set, the shaft rod is clamped on the bearing of the rotary disc with the fixedly screwed fan blades, so that the rotary disc covers the magnetic ring set, and the magnetic ring set and the shaft rod are arranged on the fixing base. When the non-loadwind power generation device is used, the fan blades are pushed by wind power to start to rotate, the rotary disc is made to rotate, a magnetic field is generated through the magnetic blocks in the rotary disc and the magneti
