[0042] The working principle of the application is as follows: before the solar panel 511 is used, the driving motor 517 is started to drive the winding rod 516 to rotate clockwise, and the protective cloth 51 is wound on the winding rod 516, the protective cloth 51 slides off the guide rod 521 and is wound on the winding rod 516, the stable rod 514 at the end of the protective cloth 51 slides upward through the guide hole 519 until the protective cloth 51 is completely separated from above the solar panel 511, the solar panel 511 in the storage groove 52 is exposed, the protrusions 515 at both ends of the stable rod 514 abut against the inner wall of the guide hole 519 to prevent the stable rod 514 from sliding out of the guide hole 519.

[0043] The hook 57 is buckled to the pull strip 513 on the surface of the solar panel 511. The servo motor 54 is started to drive the winding wheel 55 to rotate. The pull rope 56 starts to be wound. The pull rope 56 is guided by the guide frame 58 to avoid winding and jamming. The pulling force is transmitted to the solar panel 511 through the hook 57 and the pull strip 513, so that the solar panel 511 is turned up along the rotating shaft on the inner wall of the storage groove 52. At this time, the protection strip 520 on the lower surface of the solar panel 511 is separated from the partition strip 512 in the storage groove 52, so as to prevent collision and wear during turning up,

[0045] Subsequently, the air pump 67 is started. The air pump 67 inflates the air bag 64 through the air pipe 66. After the air bag 64 is inflated, the machine body 1 is lifted up, and the load plate 62 is pushed down. The load plate 62 slides downward along the slide rod 63, and the stretching spring 65 is stretched to provide a buffering force. When the air bag 64 is inflated to a preset pressure, the machine body 1 is lifted off the ground, and the support plate 61 is lowered to contact the ground along with the load plate 62, thereby forming a stable support.
