Specific embodiments

[0038] For better explaining the present utility model for easy understanding, the technical solutions and effects of the present utility model will be described in detail below in conjunction with the drawings through specific embodiments.

[0039] Such as Figures 1-15As shown in the figure, a foldable aluminum alloy photovoltaic system based on a container includes a container, a mobile frame assembly 1 that can be folded and installed inside the container, and a photovoltaic module 2 assembled on the mobile frame assembly 1. The mobile frame assembly 1 is connected to the middle of the side of the photovoltaic panel 17 of the photovoltaic module 2. This connection method can improve the product strength, reduce the stress on the frame of the photovoltaic module 2, and at the same time reduce the overall height of the product after folding, with higher space utilization. The mobile frame assembly 1 is symmetrically arranged on both sides of the photovoltaic module 2 and includes a plurality of columns 3 arranged side by side. The columns 3 are high-strength industrial aluminum profiles. The mobile frame 1 and the photovoltaic module 2 are fixedly connected by a bolt pin. The bolt pin passes through the column 3 and the frame of the photovoltaic module 2, which not only plays a role in limiting but also serves as a rotating shaft. A fixing block 5 is inserted and connected near the top of the upper end of the column 3 and is fixedly connected by bolts; a plug 13 is provided at the top of the column 3. A connecting slot is opened on the column 3, and a sliding block 6 is slidably connected in the connecting slot. A cross-shaped telescopic frame 9 is connected between two adjacent columns 3. The two connecting ends of the upper part of the cross-shaped telescopic frame 9 are connected to the fixing blocks 5 of two adjacent columns 3, and the two connecting ends of the lower part of the cross-shaped telescopic frame 9 are connected to the sliding blocks 6 of two adjacent columns 3 and are connected and limited by a bolt pin I 11. Two adjacent columns 3 approach each other, and the sliding block 6 drives the two lower connecting ends of the cross-shaped telescopic frame 9 to move downward, and the cross-shaped telescopic frame 9 contracts, driving the photovoltaic module 2 to fold; on the contrary, when two adjacent columns 3 move away from each other, the sliding block 6 drives the two lower connecting ends of the cross-shaped telescopic frame 9 to move upward, and the cross-shaped telescopic frame 9 expands, driving the photovoltaic module 2 to unfold. During the unfolding process of the photovoltaic module 2, the sliding of the sliding block 6 in the column 3 and the rotation of the two connecting rods of the cross-shaped telescopic frame 9 are achieved through close linkage to realize the unfolding function.

[0040] The contraction of the cross-shaped telescopic frame 9 includes two cross-connected connecting rods. The middle parts of the two connecting rods are connected by a bolt pin II 12, and the two can rotate relative to each other to realize the approach and separation of two adjacent columns 3, thereby realizing the folding and unfolding of the cross-shaped telescopic frame 9 driving the photovoltaic module 2.

[0041] Upper limit holes and lower limit holes are opened on the column 3. When the photovoltaic module 2 is in the unfolded state, the upper limit holes cooperate with the bolt pin III 14 and are clamped above the upper limit position of the sliding block 6 to prevent the sliding block 6 from moving upward in the unfolded state, for limiting the unfolding angle of the photovoltaic module 2; the lower limit block cooperates with the limit bolt 10 and is clamped below the upper limit position of the sliding block 6 for the upper limit of the sliding block 6 to prevent the sliding block 6 from moving downward in the unfolded state, so that the photovoltaic module 2 is always in the unfolded state.

[0042] A folding limit hole is provided in the lower part of the upright column 3. When the photovoltaic module 2 is in the folded state, the folding limit hole cooperates with the limit pin 10 and is clamped above the lower limit position of the sliding block 6, which is used for the lower limit of the sliding block 6 to prevent the sliding block 6 from moving upward in the folded state due to bumps during vehicle transportation, so that the photovoltaic module 2 is always in the folded state and prevent it from unfolding.

[0043] Before unfolding, insert the bolt III 14 into the upper limit hole to limit the unfolding position. When it is unfolded to the designed angle, the bolt III 14 restricts the sliding block 6 from moving upward continuously; at this time, insert the limit pin 10 into the lower limit hole to support the sliding block 6 and prevent it from sliding downward, playing a role in limiting. The design of this structure realizes the functions of convenient unfolding and folding through multi-directional limiting. The simple and ingenious design concept makes the photovoltaic system have detailed advantages.

[0044] A caster connector 7 is provided at the bottom of the upright column 3. The profile of the caster connector 7 is closely inserted and matched with the profile of the upright column 3. The caster assembly 8 is fixed to the lower end of the upright column 3 through the caster connector 7. The caster assembly 8 includes a connector and casters on the connector, realizing the free movement of the entire device.

[0045] The photovoltaic module 2 includes a plurality of photovoltaic units that are rotatably connected to each other. The photovoltaic unit includes a photovoltaic panel 17, a frame I 15, and a frame II 16. The frame I 15 and the frame II 16 are photovoltaic profiles and are provided with notches for installing the photovoltaic panel 17. The photovoltaic panel 17 is inserted into the notches of the profiles of the frame I 15 and the frame II 16 and fixed by welding. The assembled plurality of photovoltaic units are connected to each other through hinges 18. The folding directions of the hinges 18 on both sides of each photovoltaic unit are opposite. The middle part of the side of the photovoltaic unit is fixedly connected to the upright column 3 of the mobile frame assembly 1 through a bolt. The bolt passes through the upright column 3 and the frame of the photovoltaic module 2, and plays the role of a rotating shaft while limiting. It realizes rotation at different angles, thus meeting the functions of unfolding and folding.

[0046] When the folding aluminum alloy photovoltaic system is in the unfolded state, the angle of the photovoltaic panel 17 in the photovoltaic module 2 is 30°. When the folding aluminum alloy photovoltaic system is in the folded state, the angle of the photovoltaic panel 17 in the photovoltaic module 2 is 15°.
