The rotation central axes of the wheel hinges 3c and the non-wheel hinges 3d are arranged in parallel, the wheel hinges 3c and the non-wheel hinges 3d each comprise a hinge shaft, a turnover hinge is hingedly arranged on the side face of the hinge shaft, the hinge shaft in the wheel hinge 3c is connected downward to a roller 3c-2 through a web plate 3c-1, the web plate 3c-1 and the hinge shaft are connected through a bearing, and the roller 3c-2 is embedded in a groove arranged on the track 2. The wheel hinge 3c is simple and compact in structure, integrates rotation and support functions, is simple to install, and has the characteristics of micro-slope self-adaptation; the side face of the web plate 3c-1 is provided with a notch abutting against the A-face frame 3a and the B-face frame 3b, and the special geometric shape plays a special angle limiting role after the assembly foldable frame 3 is unfolded. The installation and fixation of the photovoltaic panels 6 on the foldable frame 3 also adopt a pressing block type front quick-opening structure, which effectively reduces the installation difficulty and the working hours required for replacing the assembly in the later period; the roller 3c-2 adopts a high-strength bearing and a plastic-coated structure, which enhances the durability and rotation stability of the overall structure.

[0034] The foldable frame 3 adopts an integrated riveting structure, which not only avoids deformation caused by welding, but also ensures the strength of the overall structure; in order to realize the folding and unfolding of the foldable frame 3 as needed, the foldable frame 3 is connected to a driving device, and the driving device controls the foldable frame 3 to be unfolded outside the storage container 1 or folded into the storage container 1. The driving device is a winch traction mechanism 4 or a sliding table mechanism 5 based on linear translation of the track 2.

[0035] In a specific embodiment, the foldable frame 3 is connected to the sliding table mechanism 5 at the end away from the storage container 1, and the sliding table mechanism 5 moves linearly away from or towards the storage container 1. The sliding table mechanism 5 includes a gear 5a driven to rotate by a motor 5b, and the track 2 is provided with a tooth hole array matched with the gear 5a.

The pull handle 8 is manually controlled to adjust the unfolding angle of the A-face frame 3a and the B-face frame 3b, realizing the adjustment of the unfolding angle of the assembly at multiple angles.

[0039] Due to the limitation of the occupied area, the total power generation of the traditional roof photovoltaic power station and off-grid photovoltaic power station is usually insufficient to support the power demand. Therefore, most of the current roof photovoltaic power stations adopt the grid-connected form, that is, the photovoltaic is integrated with the local power grid through an energy management system. Many photovoltaic power stations cannot completely operate independently without the power grid and need the support of the power grid to balance the power demand. Such a photovoltaic system obviously cannot meet the demand of some remote areas, especially areas where the power grid cannot cover. Therefore, an energy storage device 9 is arranged in the storage container 1, and an integrated power generation and inverter is also arranged, so that the power demand can be realized at any time without the need for external equipment.

[0040] ​The application adopts a novel up-down symmetrical splicing structure through a novel track design, uses staggered splicing method quick opening connection in the length direction, and moves the small wheels in the track, thereby not only ensuring the stability of the component frame during movement, but also increasing the vertical constraint between the whole component system and the track, greatly enhancing the wind resistance of the whole support system.

[0041] The use process of the container storage type photovoltaic support system is as follows:

[0042] After the whole system is transported to the construction site, the bottom of the storage container 1 is reinforced, then the side door of the storage container 1 in the length direction is opened, the track 2 is laid along the predetermined direction, the photovoltaic panel 6 assembly is unfolded through the foldable frame 3, and the internal energy storage device 9 is matched, so that the power generation and energy storage functions of the photovoltaic power station are realized.

[0043] In addition, the scheme is convenient for applying machine learning and intelligent control algorithm to the component folding and unfolding system, reduces the influence of wind load on the system, and reduces the maintenance cost; the whole support system can be quickly unfolded and folded according to real-time meteorological data and manual control, and the container can effectively prevent the photovoltaic components and energy storage and other electrical components from being damaged.

[0044] Through the above implementation mode, the container storage type photovoltaic support system of the application can realize quick installation, disassembly, transportation and storage, has high flexibility and practicality, and can be widely applied to various temporary or flexible layout photovoltaic power generation projects.

[0045] It should be noted that in the scheme of the application, the "connection" not specifically limited can be fixed connection, can be detachable connection or integral connection, and for ordinary skilled persons in the art, corresponding adjustment and transformation can be made according to specific application conditions.

[0046] Although the embodiments of the application have been shown and described, those skilled in the art can understand that various changes, modifications and replacements can be made to the embodiments without departing from the principles and purposes of the application, and the scope of the application is defined by the claims and their equivalents.
