Currently, most conventional photovoltaic structures are fixed, which are time-consuming and labor-intensive to install and remove, and have many requirements for the installation site. This cannot meet the electricity needs of troops for rapid deployment, withdrawal and transfer in plateaus and the wild. There are also some mobile photovoltaic systems, but they have high requirements for the site and poor structural controllability. Summary of the invention

[0008] The second photovoltaic array can be folded and stored in the second storage frame, and the second storage frame is slidably installed in the container through a push-pull structure. When the second storage frame is in the container, it is parallel to the first storage frame. After the second storage frame slides out from the side door of the container, the second photovoltaic array is unfolded and laid outside the container, and is parallel to the first photovoltaic array.

[0009] In the above technical solution, the push-pull structure includes two bases, a mobile frame, load-bearing rollers and positioning rollers. The two bases are installed on the inner surface of the container bottom plate at an interval and relative to each other. The load-bearing rollers and positioning rollers are installed in sequence at intervals on the opposite surfaces of the two bases. The positioning rollers are perpendicular to the load-bearing rollers. The mobile frame is slidably installed on the base. During the movement of the mobile frame, the positioning rollers and the load-bearing rollers are located on the mobile frame.

[0010] In the above technical solution, the push-pull structure also includes a wheeled leg, which is rotatably installed at the end of the movable frame. The height of the wheeled leg is adjustable. The wheeled leg includes a support wheel installed at the bottom. By rotating the wheeled leg and adjusting the height, the support wheel is in contact with the ground, thereby providing auxiliary support for the push-pull structure.

[0014] In the above technical solution, side clamping devices are provided at both ends of the first storage frame along the length direction. The side clamping devices at both ends clamp the first photovoltaic array in a folded state in the first storage frame, and the top of the first photovoltaic array is fastened in the first storage frame through the top clamping device. Two first guide rails are arranged at intervals below the first storage frame. The first guide rails are installed on the inner surface of the container bottom plate. When the first photovoltaic array is in a folded state, its bottom is slidably installed on the first guide rail. A first external guide rail is stored in the container. When the first photovoltaic array needs to be unfolded, the first external guide rail is attached to the first guide rail, and the first photovoltaic array is laid on the first external guide rail.

[0016] In the above technical solution, the photovoltaic frame group includes two photovoltaic frames, and the two photovoltaic frames are rotatably connected together by hinges. A sleeve roller is installed on each photovoltaic frame between the two photovoltaic frames to assist the first photovoltaic array and the second photovoltaic array to run on the external guide rail. The shoulder screw is installed on one of the photovoltaic frames, and the clip is installed under the other photovoltaic frame by screws. When the first photovoltaic array and the second photovoltaic array are in a folded state, the clip is clamped on the shoulder screw.

[0017] In the above technical scheme, the top clamping device and the side clamping device have the same structure, and both include a rotating connecting shaft, a first gear, a second gear, a lead screw, a nut, a fixed frame, a lead tube, a connecting frame, a moving rod, a pin shaft and a crank.

The spacing between the two first external guide rails is measured and adjusted by using the slots on the positioning tubes. After adjustment, the positioning tubes are placed at the ends of the first external guide rails to play a limiting role. When the second photovoltaic array is unfolded, two rows of second external guide rails are arranged at the bottom, and positioning tubes are also arranged at the ends of the two second external guide rails.

[0024] Step 3, plug the first external guide rail into the first guide rail, plug the second external guide rail into the second guide rail, and install a leveling device at the bottom of the first external guide rail and the second external guide rail, and adjust the height of the leveling device so that the first external guide rail is level with the first guide rail, and the second external guide rail is level with the second guide rail;

[0025] Step 4, use the positioning tube to check whether the distance between the two first outer guide rails is equal to the distance between the two first guide rails, and at the same time check whether the distance between the two second outer guide rails is equal to the distance between the two second guide rails. If not, adjust the distance between the first outer guide rails and the distance between the second outer guide rails respectively.

When the external guide rails are assembled, the slot of the positioning tube 13 is used to check whether the spacing between the corresponding two rows of external guide rails is consistent with the spacing between the two first guide rails 17 (or the two second guide rails 18). If not, adjust the spacing between the two rows of external guide rails. After the adjustment, the positioning tube 13 is installed at the end of the two rows of guide rails to further improve the structural stability. The positioning tube 13 is located at the outer end of the stop bracket 12, and the positioning tube 13 is fixed to the external guide rail by bolts.
