[0043] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific implementation disclosed below.

[0044] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which the present invention belongs. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The various technical features of the above-described embodiments can be combined arbitrarily. In order to make the description concise, all possible combinations of the various technical features in the above-described embodiments are not described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] In one embodiment, a photovoltaic device 20 is provided, such as Figure 1 As shown, the photovoltaic device 20 can be arranged on the top surface of the container 11 to collect solar energy radiated on the top surface of the container 11. Optionally, the photovoltaic device 20 can also be arranged on a roof or other platform, which is not specifically limited here.

[0047] Specifically, Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown, the photovoltaic device 20 includes a bracket 21. Figure 4 and Figure 7 As shown, a mounting position is provided on the bracket 21 , and the photovoltaic panel 22 is laid flat on the mounting position. The photovoltaic panel 22 can be raised and lowered in the mounting position to realize switching between a first position 215 and a second position 216 .

[0048] When the photovoltaic panel 22 is normally used to collect solar energy for power generation, Figure 3 and Figure 4 As shown, the photovoltaic panel 22 is located at the first position 215 of the installation position. When maintenance is required, Figure 6 and Figure 7 As shown, the photovoltaic panel 22 is located at the second position 216 of the installation location.

[0049] Specifically, Figures 2 to 7 In the illustrated solution, the first position 215 is located above the second position 216. When maintenance is required, the photovoltaic panel 22 is pulled down to the second position 216.

[0050] Optionally, the first position may also be located below the second position, that is, when maintenance is required, the photovoltaic panel 22 is pushed upward to the second position.

[0051] Furthermore, in one embodiment, the photovoltaic device 20 also includes a supporting guide member, and the supporting guide member is arranged corresponding to the second position 216. The photovoltaic panel 22 moved from the first position 215 to the second position 216 can move under the guidance of the supporting guide member, thereby making the installation position originally used to place the photovoltaic panel 22 vacant, forming a maintenance window 30.

[0052] Specifically, in one embodiment, Figures 9 to 11 As shown, the supporting guide member is a guide rail 213 disposed on the bracket 21, and the guide rail 213 extends outward from the second position 216. Figure 8 As shown, the photovoltaic panel 22 located at the second position 216 can slide along the guide rail 213. Thus, a maintenance window 30 is formed at the position originally blocked by the photovoltaic panel 22, and the operation and maintenance personnel can go up and down through the maintenance window 30 to perform maintenance on the photovoltaic device 20.

[0053] Furthermore, if Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8As shown, the photovoltaic device 20 further includes a limit assembly 23, and the limit assembly 23 is movably disposed between the bracket 21 and the photovoltaic panel 22. Figures 2 to 4 As shown, when the photovoltaic panel 22 is located at the first position 215, the limiting assembly 23 can contact the photovoltaic panel 22 to lock the photovoltaic panel 22 at the first position 215, ensuring the relative position between the photovoltaic panel 22 and the bracket 21 is stable. When maintenance is required, the limiting assembly 23 can be adjusted so that the limiting assembly 23 can unlock the photovoltaic panel 22 from the first position 215 after moving relative to the bracket 21. Figure 6 and Figure 7 As shown, the photovoltaic panel 22 is moved to the second position 216. The photovoltaic panel 22 moved to the second position 216 slides along the guide rail 213 to form the maintenance window 30, thereby improving the convenience of maintenance.

[0054] When Figures 2 to 8 As shown, when the first position 215 is located above the second position 216, the guide rail 213 can be located below the bracket 21, and the position on the photovoltaic panel 22 for contacting and cooperating with the guide rail 213 is located on the reverse side of the photovoltaic panel 22. Therefore, when the limiting assembly 23 unlocks the photovoltaic panel 22 so that the photovoltaic panel 22 falls on the guide rail 213 at the second position 216, the photovoltaic panel 22 slides along the guide rail 213 to form the maintenance window 30.

[0055] The guide rail 213 is set below the bracket 21, and the reverse side of the photovoltaic panel 22 is used to cooperate with the guide rail 213. The photovoltaic panel 22 can provide a certain shielding and protective effect on the guide rail 213. The guide rail 213 does not need to be exposed to the sun, and dust deposition is reduced, ensuring that the photovoltaic panel 22 can slide smoothly when maintenance is required.

[0056] Optionally, when the first position 215 is located above the second position 216, the guide rail 213 may also be located above the bracket 21. Fig.13 and Fig.14 As shown, a slideway 225 extending laterally may be provided on the front side 221 of the photovoltaic panel 22. When the photovoltaic panel 22 is located at the first position 215, as shown in FIG. Fig.14 As shown, the slideway 225 is suspended from the guide rail 213, and the limiting assembly 23 contacts the bracket 21 to limit the photovoltaic panel 22 to the first position 215. When maintenance is required, adjust the limiting assembly 23, such as Fig.13 As shown, the photovoltaic panel 22 is lowered to the second position 216, and the slideway 225 follows the lowering and cooperates with the guide rail 213. Figure 8As shown, the photovoltaic panel 22 is moved.

[0057] The front side 221 of the photovoltaic panel 22 described herein refers to the side of the photovoltaic panel 22 for receiving sunlight, and the back side of the photovoltaic panel 22 is the side opposite to the front side 221 .

[0058] Further, in one embodiment, if Figure 4 , Figure 5 as well as Figures 9 to 12 As shown, the guide rail 213 includes a guide groove arranged along the guide direction. Fig.15 and Fig.16 As shown, a pulley 223 is provided on the photovoltaic panel 22 at a position corresponding to the guide groove. Figure 6 and Figure 7 As shown, when the photovoltaic panel 22 moves to the second position 216, the pulley 223 is located in the guide groove. Under the cooperation and guidance of the pulley 223 and the guide groove, the photovoltaic panel 22 moves to form the maintenance window 30.

[0059] Optionally, the guide rail 213 can also be set as a strip-shaped protrusion, and a strip-shaped through groove corresponding to the strip-shaped protrusion can be set on the photovoltaic panel 22. When the photovoltaic panel 22 moves to the second position 216, the strip-shaped protrusion is located in the strip-shaped through groove, and the photovoltaic panel 22 moves to form the maintenance window 30 under the coordinated guiding action of the strip-shaped protrusion and the strip-shaped through groove.

[0060] When the second position 216 is located below the first position 215, Fig.15 and Fig.16 As shown, the pulley 223 can be arranged on the reverse side of the photovoltaic panel 22 .

[0061] Further, in one embodiment, if Fig.15 and Fig.16 As shown, a mounting frame 222 is provided on the reverse side of the photovoltaic panel 22, the pulley 223 is arranged on the mounting frame 222, and the guide rail 213 is arranged below the bracket 21. The mounting frame 222 is used to support the photovoltaic panel 22, so that the pulley 223 does not need to be directly arranged on the photovoltaic panel 22.

[0062] More specifically, in one embodiment, Figures 9 to 12As shown, the bracket 21 includes a frame body 211 and two additional parts 212 arranged below the frame body 211. The additional parts 212 include a longitudinal connecting strip 2121 and a transverse guiding strip 2122, both of which are arranged along the guiding direction of the guide rail 213. The longitudinal connecting strip 2121 is connected between the transverse guiding strip 2122 and the frame body 211. The cross section of the additional part 212 is L-shaped. The two additional parts 212 are arranged opposite to each other, the guide rail 213 is arranged on the transverse guiding strip 2122, the first position 215 is located on the frame body 211, and the second position 216 is located between the two additional parts 212 arranged opposite to each other.

[0063] When the photovoltaic panel 22 is used to receive solar power generation, the limiting assembly 23 locks the photovoltaic panel 22 with the frame body 211, so that the photovoltaic assembly is stably located in the first position 215. The second position 216 is formed between the two relatively arranged additional parts 212. When the limiting assembly 23 unlocks the locking state between the photovoltaic panel 22 and the frame body 211, the photovoltaic panel 22 descends to contact the guide rail 213 on the transverse guide strip 2122, and then moves along the guide rail 213 to form a maintenance window.

[0064] When the pulley 223 is provided on the photovoltaic panel 22 , the pulley 223 on the photovoltaic panel 22 just falls on the guide rail 213 on the transverse guide bar 2122 after being lowered.

[0065] Further, in one embodiment, if Figure 8 As shown, the guiding direction of the guide rail 213 is parallel to the plane on which the photovoltaic panel 22 is laid when the photovoltaic panel 22 is in the first position 215. That is, the photovoltaic panel 22 in the first position 215 is parallel to the photovoltaic panel 22 in the second position 216. When the photovoltaic panel 22 moves from the first position 215 to the second position 216, the angle of the photovoltaic panel 22 does not change.

[0066] When the first position 215 is located below the second position 216 , the photovoltaic panel 22 can directly fall onto the guide rail 213 of the second position 216 in parallel.

[0067] Optionally, the guiding direction of the guide rail 213 is set at an angle to the plane on which the photovoltaic panel 22 is laid when in the first position 215. That is, when the photovoltaic panel 22 moves from the first position 215 to the second position 216, it needs to rotate at a certain angle in addition to the translation.

[0068] The angle between the guiding direction of the guide rail 213 and the plane on which the photovoltaic panel 22 is laid when in the first position 215 can be selected according to actual conditions.

[0069] Furthermore, if Figure 2 , Figure 8 and Fig. 9 As shown, in one embodiment, when the guiding direction of the guide rail 213 is parallel to the plane on which the photovoltaic panel 22 is laid when it is in the first position 215, at least two installation positions are provided on the bracket 21, and the guide rail 213 is connected between the second positions 216 of the two installation positions. That is, the photovoltaic panel 22 can be pushed under the photovoltaic panel 22 of another installation position, and the two photovoltaic panels 22 can be completely overlapped or partially overlapped to save space. Moreover, with respect to the specific selection of which photovoltaic panel 22 to unlock by the bracket 21, the original installation position of which photovoltaic panel 22 the maintenance window 30 is formed can be flexibly selected according to maintenance needs.

[0070] Furthermore, in one embodiment, the guide rail 213 passes through the second positions 216 located in the same column or row. When the photovoltaic panels 22 are distributed in a ring shape, the guide rail 213 can be set to be a ring shape, and the guide rail 213 connects the second positions 216 located on the same radius.

[0071] In particular, when photovoltaic panels 22 are laid on the container 11 or the roof in order to improve utilization, increase power generation efficiency, or from the perspective of overall aesthetics. Since the roof or the top of the container 11 is covered with photovoltaic panels 22, there is no place for operation and maintenance personnel to go up and down to perform maintenance. In this case, by setting the guide rail 213 to connect between the second positions 216 corresponding to at least two installation positions, the operation and maintenance personnel can select the photovoltaic panel 22 at a suitable position for adjustment as needed, obtain the maintenance window 30, and further improve the convenience of maintenance.

[0072] Of course, for cost considerations, it is not necessary to set all photovoltaic panels 22 covering the container 11 or the roof to be able to be raised and lowered to achieve the switching between the first position 215 and the second position 216. It is only necessary to select a few photovoltaic panels 22 at appropriate positions according to the layout requirements and set them in the above-mentioned adjustable position form.

[0073] Furthermore, if Figures 2 to 8 As shown, in one embodiment, the limit assembly 23 is arranged on the photovoltaic panel 22, and the limit assembly 23 can rotate relative to the photovoltaic panel 22. When the photovoltaic panel 22 is located at the first position 215, the limit assembly 23 can rotate to achieve switching between the two states of abutment and separation with the bracket 21.

[0074] The photovoltaic panel 22 is switched between the locked and unlocked states at the first position 215 by rotating the stopper assembly 23. In addition, in the process of rotating the stopper assembly 23, the stopper assembly 23 can apply a longitudinal force to the photovoltaic panel 22, thereby adjusting the photovoltaic panel 22 from the first position 215 to the second position 216. This makes the entire adjustment process simple, fast, and more fluid.

[0075] In particular, when the first position 215 is above the second position 216, the limit assembly 23 can be set on the back side of the photovoltaic assembly, so that in the process of rotating the limit assembly 23, an upward supporting force can be applied to the photovoltaic panel 22 first, and when the limit assembly 23 unlocks the locking state between the photovoltaic panel 22 and the bracket 21, it supports the photovoltaic panel 22 to move down to the second position 216.

[0076] Optionally, the limiting component 23 may also be a structure arranged on the bracket 21, as long as it can realize the switching between the locked and unlocked states between the photovoltaic panel 22 and the bracket 21, and no specific limitation is made here.

[0077] The limiting assembly 23 can also achieve the switching between the locked and unlocked states between the photovoltaic panel 22 and the bracket 21 by translation.

[0078] When the mounting frame 222 is disposed on the reverse side of the photovoltaic panel 22 , the limiting assembly 23 may be disposed on the mounting frame 222 .

[0079] More specifically, in one embodiment, Fig.17 As shown, the limiting assembly 23 includes a locking beam 231. Figures 2 to 8 As shown, the locking beam 231 is rotatably disposed on the photovoltaic panel 22. Figures 9 to 12 As shown, the bracket 21 is provided with a limiting protrusion 214. When the photovoltaic panel 22 is located at the first position 215, as shown in FIG. Figures 3 to 5 As shown, the locking beam 231 can rotate to abut against the top surface of the limiting protrusion 214, where the top surface refers to the surface away from the ground.

[0080] The locking beam 231 is rotated along the first direction to Figure 3 As shown in the position, the end of the locking beam 231 is inserted above the limiting protrusion 214 and abuts against the top surface of the limiting protrusion 214, thereby limiting the photovoltaic panel 22 at the first position 215.

[0081] When maintenance is required, the locking beam 231 is rotated in the second direction to Figure 6In the position shown, the end of the locking beam 231 is separated from the limiting protrusion 214 , and the photovoltaic panel 22 can move to the second position 216 .

[0082] When the bracket 21 includes the frame body 211 and the attachment 212, as shown in FIG. Fig.11 and Fig.12 As shown, the limiting protrusion 214 is arranged on the inner side of the longitudinal connecting strip 2121. The inner side of the longitudinal connecting strip 2121 mentioned here refers to the side of the longitudinal connecting strip 2121 facing another additional member 212.

[0083] Further, in one embodiment, if Figures 2 to 8 As shown, the locking beam 231 is arranged on the reverse side of the photovoltaic panel 22, so that it is convenient to act on the locking beam 231 indoors, which is convenient for operation and maintenance personnel to operate.

[0084] More specifically, if Figures 9 to 12 As shown, the limiting protrusion 214 is a strip plate arranged along the guide direction of the supporting guide member, and there are two limiting protrusions 214, which are arranged opposite to each other, and the two limiting protrusions 214 are respectively used to lock the two ends of the locking crossbeam 231. When the supporting guide member includes the guide rail, the limiting protrusion 214 is arranged along the guide direction of the guide rail 213. When the locking crossbeam 231 rotates to the locking state, the two ends of the locking crossbeam 231 respectively contact the top surfaces of the two limiting protrusions 214.

[0085] When the bracket 21 includes the frame body 211 and the additional component 212 , the two limiting protrusions 214 are respectively arranged on the inner side surfaces of the two longitudinal connecting strips 2121 .

[0086] More specifically, in one embodiment, Fig.17 As shown, the locking beam 231 is an S-shaped structure. Optionally, the locking beam 231 may also be a straight plate. The S-shaped locking beam 231 can, on the one hand, prompt the operation and maintenance personnel of the rotation direction of the locking beam 231, and on the other hand, during the rotation process, the end of the locking beam 231 is gradually inserted into the top surface of the limiting protrusion 214, making the adjustment process more streamlined.

[0087] More specifically, the middle portion of the locking beam 231 is rotatably connected to the photovoltaic panel 22 .

[0088] Furthermore, if Fig.17As shown, in one embodiment, a rotating handle 232 is provided in the middle of the locking beam 231 , both ends of the rotating handle 232 are connected to the locking beam 231 , and a middle gripping portion 2321 of the rotating handle 232 is spaced from the locking beam 231 to form a gripping space.

[0089] During operation, the operation and maintenance personnel hold the middle holding portion 2321 of the rotating handle 232 and then perform a rotation process, while applying a longitudinal force to the photovoltaic panel 22 .

[0090] Furthermore, if Fig.16 As shown, in one embodiment, a rotating shaft 224 is provided on the photovoltaic panel 22 at a position for rotationally connecting with the locking beam 231. Fig.17 As shown, a bearing 233 is provided at a position corresponding to the rotating shaft 224 on the locking beam 231, and the bearing 233 is sleeved on the rotating shaft 224. Thus, the rotation process of the locking beam 231 is more streamlined, and the locking beam 231 can be rotated without applying too much force to complete the adjustment of the position of the photovoltaic panel 22.
