[0031] Working principle:

[0032] When the device is started, the motor 4 starts to work as a power source, and its output shaft drives the rotating gear 5 to rotate. The rotating gear 5 is in precise meshing with the surrounding gear 8 fixedly connected to one end of the first rotating pipe 6, so that when the rotating gear 5 rotates, the surrounding gear 8 rotates to drive the first rotating pipe 6 to rotate, thereby realizing effective transmission of power from the motor 4 to the first rotating pipe 6, which is the first step of power transmission. The first rotating pipe 6 is fixedly provided with a first limiting strip 14, and the first limiting slot 15 on the second pipe sleeve 13 cooperates with the first limiting strip 14, so that the radial movement of the first rotating pipe 6 is limited, and the smooth rotation of the first rotating pipe 6 is allowed. The second limiting strip 16 in the second rotating pipe 7 cooperates with the second limiting slot 17 on the first pipe sleeve 12 to realize stable rotation of the second rotating pipe 7. Such limiting design not only improves the rotation accuracy of the rotating pipe, but also effectively prevents loosening or deviation caused by vibration or external force interference. In order to realize the synchronous rotation of the first rotating pipe 6 and the second rotating pipe 7, the first gear 18 and the second gear 19 are fixedly connected to the upper ends of the first rotating pipe 6 and the second rotating pipe 7, respectively. The two gears are movably connected through the belt 11 provided with a gear groove 20. The gear groove 20 in the belt 11 is in close cooperation with the first gear 18 and the second gear 19, so as to ensure efficient and stable transmission of power between the two gears. When the first rotating pipe 6 rotates, the second rotating pipe 7 also rotates synchronously through the transmission of the belt 11 and the gear groove 20, thereby realizing the coordinated operation of the whole power driving device. The inside of the shell 1 is filled with high-quality soundproof cotton 10. The soundproof cotton 10 is made of advanced sound-absorbing material, which can effectively absorb the noise generated during the operation of mechanical parts and convert it into heat energy dissipated in the air. The side surface of the soundproof cotton 10 is movably connected with the side cover 2, which not only facilitates the maintenance and replacement of the soundproof cotton 10 in the future, but also ensures the close fit between the soundproof cotton 10 and the shell 1, further improving the sound insulation effect.
