[0002] With the rapid development of renewable energy technologies, photovoltaic panels, as efficient and environmentally friendly energy devices, are gradually becoming part of people's daily lives, demonstrating their unique advantages in many fields. However, as their use cases expand, traditional photovoltaic systems also have certain limitations.

[0003] On the one hand, photovoltaic modules occupy a large area and are fixed in installation, which is not conducive to mobile reuse.

[0036] The track assembly 3 includes a support rail 31, which is used to cooperate with the guide member 23 on the photovoltaic unit 21. The support rail 31 is composed of multiple rail units 311, and the rail units 311 are fixed by bolts. When the folding photovoltaic assembly 2 is in a folded state and stored inside the container body 1, a part of the rail unit 311 is stored on the top plate 14, and the other part of the rail unit 311 is set on the bottom plate 11 and is located below the folding photovoltaic assembly 2. Four support rails 31 are formed by splicing the rail units 311, and the four support rails 31 are respectively located on both sides of the bottom plate 11.

[0037] Two supporting rails 31 are respectively installed and connected on both sides of the corresponding side brackets 12 of the base plate 11. Specifically, the rail unit 311 can be fixed on the base plate 11 by bolts, etc.; the two supporting rails 31 on each side of the base plate 11 are respectively arranged in a one-to-one correspondence with the two guide members 23 on the photovoltaic unit 21.

[0038] The guide member 23 includes a guide pulley 231 , which is fixedly arranged at the end of the photovoltaic unit 21 . The guide pulley 231 is adapted to the guide rail unit 311 . When the guide pulley 231 is matched with the guide rail unit 311 , the guide pulley 231 can move along the guide rail unit 311 .

[0039] The driving assembly 4 includes four groups of chain brackets 41. When the folding photovoltaic assembly 2 is unfolded, the four groups of chain brackets 41 are used to be installed on both sides of the base plate 11. Specifically, two chain brackets 41 are respectively installed and fixed on both sides of the base plate 11 connected to the side bracket 12. The chain brackets 41 can be connected to the base plate 11 through bolts and other connecting parts. At the same time, the two chain brackets 41 located on the same side of the base plate 11 are arranged in a one-to-one correspondence with the two transmission parts 24 on the photovoltaic unit 21 (provided with a transmission part 24).

[0040] Two sprockets 43 are rotatably arranged on the chain bracket 41, and the two sprockets 43 are jointly cooperated with a transmission chain 42. The transmission member 24 is used to cooperate with the transmission chain 42, and the transmission chain 42 adopts a double-row chain structure; the driving assembly 4 also includes two motors 44 and two rotating shafts. The two chain brackets 41 on the same side of the base plate 11 are correspondingly arranged, and two corresponding sprockets 43 on the two chain brackets 41 are connected to a rotating shaft through a coupling, and the coupling is detachable to connect the sprockets 43; at the same time, the rotating shaft can pass through the sprocket 43, and by connecting the output ends of the two motors 44 on the two rotating shafts through other couplings respectively, the transmission chain 42 can be driven to move by the motor 44.

[0041] The transmission member 24 includes a transmission gear disc 241, which is fixedly arranged at the end of the photovoltaic unit 21. The transmission gear disc 241 is used to cooperate with the transmission chain 42; the transmission chain 42 can be driven to move by the motor 44. When the transmission gear disc 241 cooperates with the transmission chain 42, the folding photovoltaic assembly 2 can be driven to unfold to both sides of the base plate 11.

[0042] When using the entire foldable container solar storage system, first use a lifting device such as a car crane, forklift, etc. to lift the container body 1, so that the entire foldable container solar storage system is located directly above the site to be placed, and place a pad (steel plate, etc.) under each corner of the container body 1, and place the container body 1 on the four pads; then, remove the crossbeam 13 and the top plate 14, lift the top plate 14 and the guide rail unit 311 stored on the top plate 14, and place the top plate 14 and the guide rail unit 311 stored on the top plate 14. The photovoltaic unit 311 is placed in a suitable position, and the two side brackets 12 are unfolded; then, four support rails 31 are installed, that is, four support rails 31 are spliced together by the rail unit 311 (all rail units 311 are spliced together to form four support rails 31), and two support rails 31 are installed on both sides of the base plate 11; then, the drive assembly 4 is installed, that is, four chain brackets 41, motor 44, etc. are installed, and the transmission gear discs 241 located on the outermost two sides of the photovoltaic units 21 are respectively matched with the chains on both sides of the base plate 11.

[0043] The transmission chain 42 is driven to move by the motor 44, and the transmission chain 42 drives the transmission gear plate 241 to move; since the two adjacent photovoltaic units 21 are connected by the snap assembly 22, the photovoltaic unit 21 can be easily rotated and unfolded under the action of gravity. Before the transmission gear plate 241 on the outermost photovoltaic unit 21 disengages from the transmission chain 42, the transmission chain 42 can cooperate with the transmission gear plate 241 on the photovoltaic unit 21 adjacent to the two outermost photovoltaic units 21. When the transmission gear plate 241 on the photovoltaic unit 21 adjacent to the photovoltaic unit 21 rotated on the container is cooperated with the transmission chain 42, by driving the transmission gear plate 241 to move to the appropriate position, and relying on the action of gravity and the cooperation of the guide pulley 231 and the support guide rail 31, each photovoltaic unit 21 can be unfolded.

[0044] After unfolding, the transmission gear plate 241 on the photovoltaic unit 21 adjacent to the two middle photovoltaic units 21 does not disengage from the transmission chain 42 at this time, so that it is convenient to drive the transmission chain 42 through the transmission chain 42 to realize re-storage; due to the provision of the snap assembly 22, the unfolding inclination angle is fixed; in this embodiment, under the action of the motor 44, the folding photovoltaic assembly 2 can be automatically unfolded, which improves the unfolding effect of the folding photovoltaic assembly 2 and is convenient for quick use; when the folding photovoltaic assembly 2 needs to be stored, the folding photovoltaic assembly 2 can also be easily re-stored above the bottom plate 11 through the motor 44.

The track floor plate 3111 is used to be placed on the site. The track support 3112 can be installed on the track floor plate 3111 by means of a bolt and nut assembly, etc. The guide pulley 231 cooperates with the track support 3112.

This embodiment replaces the storage method of the track assembly 3 and the drive assembly 4 of the first embodiment, and stores the track assembly 3 and the drive assembly 4 on the transport vehicle used to transport the foldable container optical storage system. Specifically, they can be stored at the front or rear of the transport vehicle.
