[0062] DETAILED DESCRIPTION In order to more clearly illustrate the technical solutions in the embodiments of the present application or the prior art, the specific embodiments of the present application will be described below with reference to the drawings. Obviously, the drawings in the following description are only some embodiments of the present application, and for those skilled in the art, other drawings can be obtained from these drawings without creative labor, and other embodiments can also be obtained.

[0063]

[0064] ​​To keep the drawings concise, only the parts relevant to the invention are shown schematically in each figure, and they do not represent the actual structure of the product. Furthermore, for ease of understanding, in some figures, only one of components with the same structure or function is shown schematically, or only one is labeled. In this document, "one" can mean not only "only one" but also "more than one".

[0065] In recent years, with the widespread application of photovoltaic (PV) mounting systems in centralized PV scenarios, containerized PV power plants have emerged and developed rapidly worldwide. Most containerized PV power plants utilize fixed PV modules, meaning the modules are directly fixed to the top of the container. However, to achieve solar tracking, some manufacturers add angle adjustment mechanisms to the top of the container to support and fix the modules at the appropriate angle based on the sun's angle. While this type of containerized PV power plant increases power generation to some extent, its inability to achieve real-time solar tracking limits power output, and its complex overall structure and cumbersome installation hinder widespread adoption.

[0066] In one embodiment, reference is made to the accompanying drawings. Figures 1 to 9 This invention provides a containerized photovoltaic power station with photovoltaic modules that can track the sun in real time. While significantly increasing photovoltaic power generation, it simplifies the overall structure, ensures ease of production and assembly, effectively reduces costs for enterprises in centralized photovoltaic scenarios, and facilitates widespread application. (Reference) Figure 1 and Figure 2 It includes a housing 1, at least one first door 2 disposed on the housing 1, and a drive assembly 3. The drive assembly 3 is installed between the corresponding first door 2 and the housing 1 to drive the corresponding first door 2 to rotate and open or close relative to the housing 1 around a horizontal axis. Furthermore, a first photovoltaic module 4 is fixedly installed on the outer wall of the first door 2. While the first door 2 rotates and opens and closes around the horizontal axis, it drives the first photovoltaic module 4 to adjust its tilt angle in real time according to the solar angle, so as to form the first photovoltaic module 4 to track the sun in real time.

[0067] In one embodiment, based on the above embodiments, specifically referring to... Figures 1 to 9 In this embodiment, refer to Figure 2 The box body 1 has a rectangular parallelepiped structure, including a top plate 11, a bottom plate 12, and multiple columns 13. The top plate 11 and bottom plate 12 are both horizontal and spaced apart. The multiple columns 13 are preferably vertically arranged to provide stable support between the top plate 11 and the bottom plate 12. In this embodiment, the columns 13 are preferably located at the four corners of the box body 1, that is, the multiple columns 13 are distributed at the four corners of the top plate 11 and the bottom plate 12. (Refer to...) Figure 1The first door 2 is provided on each of the two opposite sides of the box 1 in the horizontal direction. After the two first doors 2 are closed, they cover the door frame area formed by the two columns 13, the top plate 11 and the bottom plate 12 at the corresponding ends of the box 1. The drive assembly 3 is installed between the side edge of the first door 2 and the corresponding column 13.

[0068] Reference Figure 2 and Figure 3 In this embodiment, the drive assembly 3 preferably includes a linear electric actuator 31, wherein both ends of the linear electric actuator 31 are formed with hinge ears 311, and the linear electric actuator 31 is rotatably connected to the first door body 2 and the corresponding column 13 through its own hinge ears 311; see reference Figure 1 and Figure 2 Push rod fixing seats 32 are installed on the side edge of the first door body 2 and on the corresponding column 13. In this embodiment, refer to Figure 3 The push rod fixing seat 32 has an L-shaped structure, including a support plate 321 and a vertical plate 322, which are perpendicular to each other and fixedly connected. The support plate 321 is used for detachable and fixed connection to the first door body 2 or the corresponding column 13. A connecting shaft 3221 is installed on the vertical plate 322 perpendicular to its own plane. The hinge lug 311 of the linear electric push rod 31 is hinged to the corresponding first door body 2 or the corresponding column 13 through the connecting shaft 3221. In one embodiment of the present invention, the connecting shaft 3221 is fixed to the vertical plate 3221. On the 22, a bearing structure is fixedly installed inside the hinge lug 311 of the linear electric actuator 31. The outer ring of the bearing structure is coaxially fixed to the hinge lug 311, and the inner ring of the bearing structure is coaxially fixed to the connecting shaft 3221, thereby realizing the rotatable installation of the linear electric actuator 31 relative to the first door body 2 and the corresponding column 13. In other embodiments of the present invention, the connecting shaft 3221 may also be rotatably connected to the upright plate 322 around its own axis, and the hinge lug 311 of the linear electric actuator 31 may be fixed to the connecting shaft 3221. Of course, other structural forms may also be used to realize the rotatable connection between the linear electric actuator 31 and the first door body 2 and the corresponding column 13, which will not be elaborated here.

[0069] In this embodiment, to enhance the structural strength of the first door 2 supporting the first photovoltaic module 4, at least two linear electric actuators 31 are preferably spaced apart for each first door 2; and the two linear electric actuators 31 are electrically connected through a controller to ensure synchronous operation at both ends of the first door 2. Simultaneously, each linear electric actuator 31 located on opposite sides of the housing 1 in the horizontal direction is also electrically connected through a controller to keep all the first photovoltaic modules 4 on opposite sides of the housing 1 in the horizontal direction parallel, thereby facilitating synchronous tracking and driving of the first photovoltaic modules 4.

[0070] Refer to Figure 2In this embodiment, to increase the capacity of the photovoltaic modules in the containerized photovoltaic power station, it is preferable that the first door 2 is located on both sides of the width direction of the container 1, that is, the horizontal extension direction of the first door 2 is parallel to the length of the container 1, so as to maximize the mounting surface of the first photovoltaic module 4 while keeping the height of the first door 2 constant. The first photovoltaic module 4 is detachably mounted on the outer wall of the corresponding first door 2 via a purlin array. Based on this, in one embodiment of the present invention, multiple columns 13 can be installed on both sides of the width direction of the container 1, and the multiple columns 13 are spaced apart on the corresponding sides of the container 1 to improve the support strength of the container 1 for the first photovoltaic module 4. Furthermore, it is possible to further arrange two adjacent columns 13 to correspond to one first door 2, or multiple adjacent columns 13 to correspond to one first door 2, that is, the number of first doors 2 on either side of the width direction of the container 1 is unlimited.

[0071] Furthermore, refer to Figure 2 The box body 1 has two second doors 5 on its two horizontally adjacent sides to the first door 2, i.e., the second doors 5 are located on opposite horizontal sides of the box body 1. Based on the above embodiment, it is preferable that the second doors 5 are located on both sides in the length direction. The second doors 5, together with the first door 2, the top plate 11, and the bottom plate 12, together enclose the accommodating space of the box body 1; refer to Figure 1 The container space is equipped with multiple second photovoltaic modules 6 to further expand the module capacity of the containerized photovoltaic power station. In practical applications, when power generation is not required or the required power is small, the multiple second photovoltaic modules 6 are folded and stored in the container space to shut down the containerized photovoltaic power station or generate power solely by the first photovoltaic module 4. When a large amount of power generation is required, the second door 5 is opened, and the multiple second photovoltaic modules 6 unfold and extend out of the container space in sequence along a direction perpendicular to the second door 5. That is, the second photovoltaic modules 6 can unfold and extend out of the container space along the length of the container 1 to generate power independently or simultaneously with the first photovoltaic module 4.

[0072] Reference Figure 1 and Figure 2 To prevent the top plate 11 from obstructing the second photovoltaic module 6 after it is unfolded, in this embodiment, a set of the second photovoltaic module 6 is provided for each of the two second doors 5. Of course, each set of the second photovoltaic module includes multiple second photovoltaic modules 6. Furthermore, a guide 7 can be detachably installed on the box 1 for each set of the second photovoltaic modules 6. The guide 7 extends along the length of the box 1 to assist in unfolding or folding the multiple second photovoltaic modules 6.

[0073] Specifically, refer to Figure 1 , Figure 4Each guide member 7 on the housing 1 is provided with multiple component frames 61, which are connected end to end in sequence so that any group of multiple second photovoltaic modules 6 are arranged in an S-shaped folding arrangement. In this embodiment, it is preferable that each component frame 61 is formed by riveting four rectangular square tubes end to end in sequence, avoiding the use of rod welding process, so as to reduce the probability of thermal deformation of the component frame 61 caused by the high temperature of the welding process; at the same time, each component frame 61 has a lap plate welded to its four corners, and each second photovoltaic module 6 is fixedly placed on multiple lap plates in the corresponding component frame 61, so that its top and bottom surfaces do not protrude from the corresponding end faces of the two openings of the component frame 61, so as to avoid collision and squeezing damage during the folding process. At the same time, the component frame 61 forms a corner-wrapping structure for the second photovoltaic module 6, which not only effectively enhances the connection strength between the two, but also helps to further increase the safety of construction and reduce the probability of damage to the second photovoltaic module 6.

[0074] Reference Figures 4 to 8 In this embodiment, adjacent component frames 61 are preferably connected end-to-end by a 360-degree hinge 62, that is, the 360-degree hinge 62 is disposed between adjacent component frames 61; see reference Figure 5 The 360-degree hinge 62 includes two hinge pieces 621 and a hinge shaft 622 connecting the two hinge pieces 621. During assembly, the two hinge pieces 621 of the 360-degree hinge 62 are detachably connected to the corresponding edges of adjacent component frames 61, and then connected to the corresponding two hinge pieces 621 via the hinge shaft 622, thereby realizing the rotational connection of adjacent component frames 61. In this embodiment, it is preferable to provide at least two sets of 360-degree hinges 62 at intervals between adjacent component frames 61 to improve the smoothness of the folding and unfolding process of the second photovoltaic module 6, as well as the convenience and safety of the installation operation. Furthermore, it is preferable that the ends of the two hinge pieces 621 of any 360-degree hinge 62 that are away from the hinge shaft 622 protrude from the installation area of ​​the second photovoltaic module 6 inside the component frame 61 to improve the stability of the second photovoltaic module 6 installed inside the component frame 61 and to prevent the second photovoltaic module 6 from detaching from the component frame 61 as much as possible.

[0075] In addition, refer to Figures 5 to 8 A traveling component 63 is also provided between two adjacent component frames 61 corresponding to the 360-degree hinge 62, to cooperate with the guide 7 to achieve stable movement of the component frame 61 along the length direction of the housing 1; specifically, in this embodiment, the traveling component 63 includes a support plate 631 and a traveling wheel 632, wherein the support plate 631 is arranged perpendicular to the hinge axis 622, and one end of it is coaxially hinged to the two hinge pieces 621 of the 360-degree hinge 62 through the hinge axis 622, while the other end is used to install the traveling wheel 632; see reference Figure 3To further enhance the safety of the installation process of the second photovoltaic module 6, in this embodiment, the walking wheel 632 includes at least two wheel sets spaced apart along the direction of movement. Each wheel set includes two wheel bodies coaxially rotatably connected and a pivot shaft connecting the two wheel bodies. The two wheel bodies are located on both sides of the thickness of the support plate 631 and are hinged to the support plate 631 through the pivot shaft. In this embodiment, both wheel bodies are rotatably connected to the pivot shaft through oil-free self-lubricating radial bearings. That is, oil-free self-lubricating radial bearings are installed between the ends of the pivot shaft corresponding to the two wheel bodies and the corresponding wheel bodies, so that each wheel set has a preset small slope adaptive capability along its own axis.

[0076] Reference Figure 7 and Figure 8 In this embodiment, the support plate 631 has a "V"-shaped structure corresponding to the 360-degree hinge 62 and the two wheel sets. The 360-degree hinge 62 and the two wheel sets are located at the three free ends of the support plate 631. Of course, in order to allow the ends of the two adjacent component frames 61 away from the guide member 7 to be completely folded, in this embodiment, the walking component 63 is only assembled at the 360-degree hinge 62 at the end of the component frame 61 that connects to the guide member 7.

[0077] Reference Figure 9 For the guide member 7, this embodiment is preferably configured as a slide rail with a slide groove having an inverted T-shaped cross-section. The slide groove includes a small diameter section and a large diameter section arranged sequentially and connected along the depth direction, so that the walking component 63 is rolled and embedded in the slide groove along the length direction of the slide rail. This maintains the support plate 631 sliding and cooperating with the inner wall of the small diameter section along the length direction of the slide rail, and the two wheels are respectively close to the two side walls of the large diameter section, thereby realizing the smooth movement of the component frame 61 along the slide rail.

[0078] In this embodiment, to further improve the convenience of production and assembly, refer to Figure 1 and Figure 9 The slide rail comprises multiple track segments 71 joined end-to-end along its own length; see reference. Figure 2Each of the track segments 71 includes an upper track 711 and a lower track 712. A groove is formed on the upper end face of the upper track 711. The lower track 712 includes a main body segment 7121 and an extension segment 7122. The main body segment 7121 has the same structural form as the upper track 711. The main body segment 7121 of the lower track 712 is opposite to the groove of the upper track 711, and the two are arranged in parallel and staggered configurations. That is, the first end of the lower track 712 is located at the middle of the upper track 711 along its length, and the second end of the lower track 712 extends beyond the corresponding end of the upper track 711. The end face; the extension 7122 is formed on the second end of the lower rail 712 and is adapted to the size and shape of the slide groove; during actual assembly, the second end of any lower rail 712 slides relative to the first end of the upper rail 711 of the adjacent rail segment 71 along the length direction of the slide rail, and its extension 7122 slides synchronously and is embedded in the slide groove of the lower rail 712 of the adjacent rail segment 71, until the second end of the body abuts against the first end of the body segment of the adjacent rail segment 71, and the second end of the upper rail 711 abuts against the first end of the upper rail 711 of the adjacent rail segment 71. In addition, in order to stably connect the two adjacent rail segments 71, a connecting member is also provided on the slide rail.

[0079] Reference Figure 9 Each extension segment 7122 is provided with a first through hole 71221, which is horizontally located at the middle of the length of the extension segment 7122 and vertically penetrates the two side walls of the large-diameter end of the corresponding slide groove. Correspondingly, the first end of the main body segment 7121 is provided with a second through hole 71211, which is configured in the same way as the first through hole 71221. After the extension segment 7122 of any track segment 71 is fully embedded into the first end of the main body segment 7121 of the adjacent track segment 71, the first through hole 71221 and the second through hole 71211 are connected. Then, by connecting the first through hole 71221 and the second through hole 71211 simultaneously, the two adjacent track segments 71 can be stably connected along the length of the slide rail. In this embodiment, the connecting member can be set as a pivot such as a pin or screw. This configuration, where adjacent lower rails 712 are connected by a connector rotating around a horizontal axis, allows the slide rail to have a certain slope adaptive characteristic along its own length direction. This adapts to the construction requirements of containerized photovoltaic power stations on project grounds with a certain slope, effectively enhancing the practicality of the containerized photovoltaic power station.

[0080] In practical applications, winches are installed for both the component frames 61 near the end of the housing 1 and the component frames 61 away from the housing 1 for any group of second photovoltaic modules 6. Specifically, a first winch is installed inside the housing 1. The first winch drives the component frames 61 away from the housing 1 to move towards the housing 1 until all component frames 61 return to the housing 1's storage space and are stacked sequentially along the thickness direction, thus achieving the folding and storage of the second photovoltaic modules 6. Similarly, a second winch is installed outside the housing 1 on the side of the slide rail away from the housing 1. The second winch drives the component frames 61 away from the housing 1 to gradually move out of the housing 1 in a direction perpendicular to the second door 5 until any component frame 61 is roughly laid flat, thus achieving the unfolding drive of the second photovoltaic modules 6.

[0081] In an embodiment of the present invention, in order to enable the second photovoltaic module 6 to have multiple unfolded states at various angles, it is preferable to add a limiting tie rod structure between several module frames 61, and the limiting tie rod structure is preferably located on the side of the module frame 61.

[0082] It is worth noting that, in this embodiment, reference is made to... Figure 2 To prevent the second door 5 from obstructing the first photovoltaic module 4 and / or the second photovoltaic module 6 after it is opened, the second door 5 is configured as a roller shutter door structure that retracts and opens from bottom to top.

[0083] In addition, refer to Figure 1 and Figure 2 The containerized photovoltaic power station also includes an integrated charging and discharging inverter, an energy storage battery, and other electrical modules 8, to facilitate power extraction through the containerized photovoltaic power station without the need for external equipment. In this embodiment, two side plates 14 are provided in the middle of the container body 1 along its length. Both side plates 14 are parallel to the length of the container body 1 and are located at both ends of the width of the container body 1. The electrical modules 8 are integrated within the accommodating space and located between the two side plates 14, so as to shield and protect the electrical modules 8 with the help of the side plates 14.

[0084] Furthermore, to further expand the component capacity, the containerized photovoltaic power station also includes a third photovoltaic module 9, which is fixedly installed above the top plate 11 by purlins, and the first photovoltaic module 4, the second photovoltaic module 6 and the third photovoltaic module 9 are all electrically connected to the electrical module 8.

[0085] The implementation principle of this invention is as follows: In addition to horizontally installing the third photovoltaic module 9 on the top plate 11 of the container 1, the first photovoltaic module 4 is installed on the outer wall of the first door 2. The first door 2 and its flipping drive component 3 are used to realize solar tracking drive of the first photovoltaic module 4. At the same time, the second photovoltaic module 6 is integrated at the bottom of the container 1 by folding. The second photovoltaic module 6 is unfolded and folded by means of the winch and the embedded sliding cooperation of the double-wheeled walking wheel 632 and the slide rail. The containerized photovoltaic power station has a large photovoltaic module capacity, high power generation efficiency, simple form, and convenient production and use, which effectively promotes cost reduction and efficiency improvement for enterprises.

[0086] It should be noted that the above embodiments can be freely combined as needed. The above description is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
