Specifically, the first power unit comprises a fixed seat 22, a servo motor 23 arranged on the fixed seat 22 and a driving wheel 24 arranged in the fixed seat 22, wherein the driving wheel 24 is connected with the servo motor 23; the fixed seat 22 is fixedly connected with the shelter, and the driving wheel 24 is meshed with the rotary gear 21. The servo motor 23 works to drive the driving wheel 24 to rotate, so that the rotating gear 21 is driven to rotate, the base 11 is driven to rotate, and finally the spherical cover body is driven to rotate.
In some embodiments, the rotary gear 21 includes a slewing bearing inner ring 211 and a slewing bearing outer ring 212 rotationally connected with the slewing bearing inner ring 211, the slewing bearing inner ring 211 is fixedly connected with the shelter, the slewing bearing outer ring 212 is fixedly connected with the base 11 (a flange interface is arranged at the bottom of the base 11, the base 11 is rigidly connected with the slewing bearing outer ring 212 through screws), and the driving wheel 24 is in meshed connection with the slewing bearing outer ring 212.
