[0049] In the technical solution of this application, the entire lightweight unmanned transportation platform uses the lightweight platform 1 to achieve the unmanned transportation function. When the unmanned transportation platform 1 is in air transportation, the lifting and lowering of the platform 1 and the chassis 2 are realized through the operation of the power device 8. At this time, the third hydraulic cylinder 20 shortens and drives the rotating rod 21 to rotate, which drives the rollers 22 to be retracted, so that the rollers 22 move above the support rod 13. When landing, the support rod 13 touches the ground first.

At this time, both the support rod 13 and the rollers 22 are retracted. The floating block 27 plays a floating role, and the rotation of the impeller 26 in the turbine 25 provides the moving power. When moving, when the second motor 23 drives the deflector 24 to rotate, the moving direction is controlled by the deflector 24;

[0050] During land transportation, the third hydraulic cylinder 20 extends to push the support rod 13 to rotate to a vertical position, so that the rollers 22 touch the ground to provide support. The rotation of the rollers 22 drives the platform 1 and the chassis 2 to move. When moving, when the first motor 18 drives the gear 19 to rotate, the gear 19 meshes with the tooth groove 15 at the telescopic end of the second hydraulic cylinder 14, thereby driving the chassis 2 to rotate inside the mounting seat 16. When the bottom plate 17 rotates at the bottom of the telescopic end of the second hydraulic cylinder 14, it drives the support rod 13 and the rollers 22 to turn, thereby realizing the control of the direction. At the same time, the second hydraulic cylinder 14 extends to drive the bottom plate 17 to move inside the mounting seat 16, so that the bottom plate 17 moves inside the mounting seat 16 at the bottom, thereby adjusting the height of the chassis 2 to be suitable for the height of the ground. The road surface conditions are monitored by the camera 7, and the height of each roller 22 is adjusted to adapt to the movement on different uneven road surfaces. At the same time, after the chassis 2 is raised, it has an effective obstacle avoidance function, which improves the practicability of the unmanned transportation platform 1; when in use, the cylinder 4 extends to drive the protective cover 3 to rotate around the platform 1, realizing the opening of the protective cover 3, realizing the transportation of the drone 31 on the base 30, and information collection is realized through the drone 31. When moving, the cylinder 4 shortens to drive the two protective covers 3 to close. At this time, the sealing strips 5 are driven to fit together to achieve sealing. At the same time, the inner wall of the bottom of the protective cover 3 contacts the sealing gasket 29 on the surrounding plate 28, realizing the effective sealing of the bottom of the protective cover 3, avoiding rainwater from entering the inside of the protective cover 3, and improving the practicability of the unmanned transportation platform 1.
