As shown in Figure 5, the second preferred embodiment of the utility model wind power generation device is roughly the same as the first preferred embodiment, the difference is that the present embodiment narrows the front end of the first flow channel 201 and the second preferred embodiment. The diameter of the front end of the second flow channel 202 is such that the airflow can enter the first flow channel 201 and the second flow channel 202 in a concentrated manner, and it is not easy to generate turbulent flow, so as to increase the driving pressure of the introduced wind flow, and then increase the first blisk 321 and the second flow channel 202. The rotating speed of two blisks 331, and, this first wheel disc 324, the second wheel disc 334 and the first disc body 414, the second disc body 424 ratio stretch, make the diameter length of this first and second wheel disc obviously The ground is larger than the diameter length of the first and second disks, so that the rotation speed of the first disk 414 and the second disk 424 can be accelerated, thereby improving the overall power generation efficiency. the

As shown in FIG. 6 , the third preferred embodiment of the wind power generation device of the present invention is installed on an electric vehicle driven by pure electric power. Since the engine room of an electric vehicle has no components such as a cylinder and has a relatively large space, the wind power generation device can be designed to be relatively wide and flat to use the effective space in the engine room to allow more air to enter and generate more power. , In addition, the storage battery 6 of the present embodiment is provided on the chassis of the vehicle 5 . the

As mentioned above, the wind power generation device of the utility model utilizes the first rotating group 32 and the second rotating group 33 of the rotating unit 3 to be rotated by the airflow at the same time, and respectively drives the first generating module 41 and the second generating module. The module 42 rotates in the opposite direction, so that the second power generation module 42 and the first power generation module 41 rotate in opposite directions to generate larger power, thereby improving the overall power generation efficiency, so the purpose of the utility model can indeed be achieved. the
