The turbine 15 is fixedly mounted on one side of the rotating ring 7. There are two rotating support plates 16, and the two rotating support plates 16 are fixedly mounted on one side of the annular mounting plate 3. The worm 17 is rotatably mounted between the two rotating support plates 16. The worm 17 is meshed with the turbine 15.
