Detailed ways

Below in conjunction with accompanying drawing, specific embodiment is described:

As shown in Figure 1, a wheel-type windmill generator includes a bracket 1, and the top of the bracket 1 is fixedly connected with a rotating seat 2 that can fix the subsequent workpiece and rotate freely at 360°. The rotating seat 2 is equipped with a freely rotatable impeller. Rotating shaft 3, one end of the impeller rotating shaft 3 protrudes from the rotating seat 2 and is fixedly connected with an impeller 4, the other end is connected with a main transmission shaft 5 installed on the bracket 1 through a gear, and the bottom end of the main transmission shaft 5 is connected with a generator machine 6, the impeller 4 includes a central disc 14 connected to the impeller rotating shaft 3, and the central disc 14 is fixedly connected with a plurality of fan blade main rods 7 extending outward, and the plurality of fan blade main rods The ends of 7 are jointly fixedly connected with an annular large fan blade support ring 8, the middle part of which is jointly fixedly connected with an annular middle fan blade support ring 9, and its roots are jointly fixedly connected with an annular small fan blade support ring 10, where the large fan blade supports There are several fan blades 11 connected between the ring 8 and the middle fan blade support ring 9, and between the middle fan blade support ring 9 and the small fan blade support ring 10, and the middle part of each fan blade 11 blade and the main fan blade Rod 7 is fixedly connected.
