Embodiment 1
[0032] From Figure 1 ~ Figure 4 It can be seen that the technical solution of the present invention includes a main frame 1, a guide frame 12, a shroud 10, an impeller 2, a main shaft 8, a coaxial asynchronous mechanism, and a transmission mechanism;
[0033] The main shaft 8 used for power output is vertically assembled in the main frame 1, the middle part of the frame body of the guide frame 12 is assembled on the upper section or the top of the main shaft 8, and a coaxial asynchronous mechanism is arranged between the frame body of the guide frame 12 and the main shaft 8, and the guide frame 12 Rotate horizontally around the axis of the main shaft 8 through a coaxial asynchronous mechanism;
[0034] The coaxial asynchronous mechanism in this embodiment includes a vertical shaft 9b coaxially assembled with the main shaft 8 and a bearing seat 9a fixedly connected to the top of the main shaft 8. The vertical shaft 9b vertically passes through the guide frame 12 and is fixedly...
Embodiment 2
[0043] From Figure 5 ~ Figure 6 It can be seen that the difference between this embodiment and Embodiment 1 is that the main shaft 8 vertically runs through the body of the guide frame 12, the coaxial asynchronous mechanism is a group of bearings respectively arranged in the middle of the upper and lower end faces of the guide frame 12, and the guide frame 12 passes through the set of bearings. The bearing is assembled on the upper section of the main shaft 8 .
[0044] Another difference between this embodiment and Embodiment 1 is that the blades of the impeller 2 are hingedly connected to the impeller shaft 3 , and the hinged part of the blades and the impeller shaft is provided with a return spring and a limit card to prevent the blades from swinging excessively in reverse. When working in a windy environment, when the airflow flows through the blades, the blades can swing slightly backwards to avoid damage; the blades can also be made of deformable elastic materials such ...
Embodiment 3
[0046] From Figure 7 It can be seen that the difference between this embodiment and Embodiment 1 or Embodiment 2 is that the transmission mechanism between the impeller shaft and the main shaft adopts spur gear transmission, and its structure is: the lower ends of the impeller shafts 3 on both sides are respectively provided with a driving gear 16, and the main shaft 8 is provided with a driven gear 18, and the driving gears 16 on both sides are respectively connected and transmitted with the driven gear 18 of the main shaft through an intermediate gear set 17. In order to ensure the direction of rotation of the main shaft, the number of gears in the gear set 17 of the transmission mechanism on the left and right sides is odd and even numbers respectively, so as to realize conversion of the direction of rotation.
