Description

Technical Field

[0001] This application relates to the field of photovoltaic technology, and further relates to an integrated photovoltaic and energy storage device. Background Art

[0002] Currently, in some photovoltaic power generation scenarios, containers are used as carriers of energy storage systems, and photovoltaic modules are installed on the top to form an "integrated photovoltaic and energy storage" device. However, in most existing solutions, the brackets of the photovoltaic modules are directly fixed to the box structure by drilling holes or performing high-temperature welding on the top of the container. This not only easily causes structural damage to the top plate of the box, but also leads to reliability hazards such as rain leakage due to seal failure. In addition, the welded connection parts are vulnerable to corrosion in the long-term outdoor environment, resulting in rust and embrittlement, which further affects the support stability of the photovoltaic modules.

[0003] Secondly, the space on the top of the existing container is limited. If only fixed brackets are used to install photovoltaic modules, it is often impossible to obtain the best sunshine angle, resulting in low utilization rate of the photovoltaic modules. Summary of the Invention

When the fixed component is connected to the container, the connecting body is connected to the fixing member, and the limiting baffle abuts against the outer surface of the corner fitting and covers the corresponding second preset interface.

[0012] In some embodiments, each of the support members is provided with at least two cantilever ends arranged at intervals in the height direction. The extending direction of the cantilever ends is perpendicular to the central axis of the support member. Two of the cantilever ends and the support member together form a groove-like structure, and the groove-like structure serves as the installation part, so that different edges of the photovoltaic module can be simultaneously clamped into the corresponding groove-like structure, thereby completing the installation of the photovoltaic module.

[0025] It should be further understood that the term "and / or" used in the specification and claims of the present application refers to any combination and all possible combinations of one or more of the related listed items, and includes these combinations.

[0026] In this document, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0027] In the description of the present application, it should be understood that the orientation or positional relationships indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. are based on the orientation or positional relationships shown in the drawings. These are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present application.

[0028] With the development of distributed energy technologies, the integrated integration of photovoltaic systems and energy storage systems has gradually become an efficient and flexible energy solution. Especially in scenarios such as field operations, power supply guarantee, emergency rescue, and power supply in remote areas, containers are often used as carriers of energy storage systems and combined with photovoltaic modules to form integrated photovoltaic-energy storage devices.

[0029] However, there are still many problems in the existing structural design of installing photovoltaic modules on the top of containers. Most existing solutions directly fix the photovoltaic brackets to the container top plate by welding, drilling, etc. Such methods are likely to damage the original structure of the container. On the one hand, it destroys the overall rigidity and sealing performance of the top plate, and it is easy to cause rainwater leakage due to seal failure during use, affecting the electrical safety of the energy storage system. On the other hand, the welded parts are easily corroded and embrittled when exposed to wind, sun, and rain erosion outdoors for a long time, which may lead to unreliable fixation of the photovoltaic brackets, structural fatigue, and even detachment, seriously affecting the operation stability and safety of the system.

[0030] In addition, the space on the top of the container is limited. If only the layout method of photovoltaic modules with a fixed angle is adopted, it is often impossible to make full use of solar resources, resulting in low power generation efficiency.

[0031] In addition, in the description of the present application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0032] In one embodiment, referring to the attached drawings of the specification Figure 1 , an integrated photovoltaic-energy storage device provided by the present application is described. The integrated photovoltaic-energy storage device provided by the present application can avoid damaging the container top plate, and at the same time improve the layout efficiency of photovoltaic modules and the overall power generation performance.

[0033] Referring to the attached drawings of the specification Figures 1 to 3, An integrated solar and energy storage device provided by this application includes a container 1, multiple corner fittings 11, a first photovoltaic power generation system, and a second photovoltaic power generation system. Among them, the first photovoltaic power generation system includes a fixed support structure 2 and a first photovoltaic module 41 installed on the fixed support structure 2, and the second photovoltaic power generation system includes a tracking support structure 3 and a second photovoltaic module 42 installed on the tracking support structure 3. This device can be set up off-grid and can achieve integrated power generation and energy storage.

[0034] The container 1 serves as the main structural foundation, and an energy storage system 120 and other devices are arranged inside it for storing the electric energy from the photovoltaic modules. The energy storage system 120 can include functional components such as a battery pack, and the battery pack is used for storing the electric energy collected by the photovoltaic modules.

[0035] Specifically, in addition to the energy storage system 120, the integrated solar and energy storage device further includes an inverter 130. The inverter 130 is electrically connected to the photovoltaic modules (the photovoltaic modules refer to the first photovoltaic module 41 and / or the second photovoltaic module 42. For the sake of simplicity, the same applies hereinafter). The inverter 130 is used to convert the direct current output by the photovoltaic modules into alternating current for supplying external loads, and / or the inverter 130 is used to convert the direct current output by the photovoltaic modules into direct current with a voltage match and store it in the energy storage system 120; correspondingly, the battery pack of the energy storage system 120 is electrically connected to the inverter 130.

[0036] Multiple corner fittings 11 are respectively arranged in the top corner areas or the top surface frame of the container 1, playing a key role in the lifting and handling operations of the container, bearing the acting force and protecting the entire box body, and can be used to provide positioning and mechanical connection interfaces for the subsequent installation of the photovoltaic support, thereby avoiding opening holes or welding on the top plate of the container 1, and thus protecting the box body's sealing performance and structural integrity.

[0037] The fixed support structure 2 is used to carry a certain amount of the first photovoltaic module 41, and at least part of the structure is mechanically connected to the above-mentioned corner fittings 11, so as to stably install the first photovoltaic module 41 on the top of the container 1. The tracking support structure 3 is arranged on at least one side of the container 1, and a second photovoltaic module 42 is installed on the tracking support structure 3 (the first photovoltaic module 41 and the second photovoltaic module 42 can adopt the same specifications or different specifications. In this application, only the "first" and "second" are used to distinguish the photovoltaic modules on different supports), and can adjust the angle of the photovoltaic module (such as pitching around the horizontal axis) according to a preset solar tracking algorithm or control logic to adapt to the change of the solar altitude angle at different time periods.

[0038] The second photovoltaic power generation system is installed in the container 1 and extends to at least one side of the container 1 to form at least one row of photovoltaic power generation systems on the peripheral side of the container 1. It can be understood that the tracking bracket structure 3 is centered on the container 1 and can be flexibly arranged on one side, both sides or even three sides of it. Generally, only the door of the container needs to be avoided so as not to affect daily maintenance and personnel access. Correspondingly, preset electrical interface openings can be provided on the corresponding side walls of the container 1 for connecting the cable lines of the external tracking bracket and introducing them into the interior of the box to form a complete power circuit.

[0039] In this way, through the setting of this embodiment, that is, by setting the fixed first photovoltaic module 41 on the top of the container 1 and the tracking second photovoltaic module 42 on one side or multiple sides, not only the photovoltaic power generation area is expanded, but also the utilization rate of the energy storage device is significantly improved, enabling the energy efficiency of the device to be maximized. The integrated energy storage and photovoltaic device in this embodiment can be used for the construction of fixed power stations and is also suitable for scenarios such as field emergency power supply, etc., having good versatility and expandability.

[0040] Optionally, in this embodiment, the fixed bracket structure 2 can be a support frame or an assembled frame and other similar structures. For example, the fixed bracket structure 2 includes a plurality of longitudinally arranged load-bearing beams and laterally arranged photovoltaic module installation tracks. The bottom of the load-bearing beam is connected to the corresponding position of the corner fitting 11 to form a stable installation framework, and the photovoltaic modules can be sequentially installed into the installation framework through the installation tracks.

[0041] In addition, the fixed bracket structure 2 can further include a module angle adjustment mechanism or a module orientation adjustment mechanism to optimize the light utilization efficiency in the top area of the container.

[0042] Based on the above embodiment, in one embodiment, the fixed bracket structure 2 includes a plurality of fixing components 21 and at least two supporting components 22. Among them, each supporting component 22 is respectively connected to different edge areas on the top of the container 1 through the corresponding fixing component 21, preferably the opposite sides or the four-corner edge areas on the top, so that the overall fixed structure has good force balance and structural stability.

[0043] As Figure 3 and Figure 7 shown, each supporting component 22 has an installation portion 220 arranged along its length direction, and the installation portion 220 is used to cooperate with the installation of at least one first photovoltaic module 41. Typically, it can be structural forms such as a positioning groove, a positioning hole, a convex guide rail, etc., so as to realize the arrangement and connection of the first photovoltaic module 41 in the horizontal direction or the inclined direction.

[0044] Furthermore, as Figure 4As shown, each fixing component 21 includes at least one first connecting portion 211 and a second connecting portion 212. Among them, the first connecting portion 211 is connected to a preset position of the support member 22, for example, connected to the bottom or side wall of the support member 22 through bolts, pins or snap - type connection structures, so as to achieve reliable positioning between the support member 22 and the fixing component 21.

[0045] The second connecting portion 212 is used to connect with the corner fitting 11 on the container 1. The corner fitting 11 is arranged at the top edge of the container 1, for example, in the corner connection area of the container 1, to provide good load - bearing support capacity, and avoid drilling or welding on the top plate of the container 1, thereby effectively reducing the impact on the overall sealing performance and structural strength of the container body.

[0046] It can be understood that in this embodiment, through the design of the fixed bracket structure 2, the stable installation of the photovoltaic module on the top of the container can be realized, and reliable fixation is achieved by using the inherent structural connection parts of the container 1, avoiding problems such as top - plate damage, rust and leakage caused by the traditional container drilling and welding methods.

[0047] Furthermore, each component of the fixed bracket structure 2, such as the fixing component 21, the support member 22, etc., can be processed and stored separately. During the transportation of the components, they can be scattered for storage, and then quickly assembled and positioned on - site, thus significantly improving the installation efficiency and transportation convenience, making the integrated energy storage and photovoltaic equipment applicable to deployment and application in various scenarios.

[0048] In one embodiment, as Figure 4 shown, a connection base 213 is also provided in each fixing component 21. The connection base 213 is arranged between the first connecting portion 211 and the second connecting portion 212 in the height direction of the fixing component 21, that is, it constitutes the structural transition part between the two connecting portions. Specifically, since the first connecting portion 211 is connected to the support member 22, and the first photovoltaic module 41 is cooperatively installed on the support member 22, the distance between two opposite first connecting portions 211 matches the specification of the first photovoltaic module 41. In addition, the distance between two opposite second connecting portions 212 matches the distance between two opposite corner fittings 11, that is, it matches the width of the container 1. Therefore, through the setting of the connection base 213, the first connecting portion 211 and the second connecting portion 212 can be stagger - arranged in the width direction of the container 1, so as to release the dimensional binding constraint between the specification size of the first photovoltaic module 41 and the width of the container 1.

[0049] In a specific installation state, when the support member 22 is fixed to the container 1 through the corresponding fixing member 21, the connecting base 213 can form at least partial abutment with the support member 22, for example, directly contact the side wall, bottom or mating surface of the support member 22, so as to play a role of vertical support and limit in structure, further enhancing the fixing reliability and stability of the support member 22.

[0050] At the same time, the connecting base 213 can also form at least partial abutment with the corner fitting 11, for example, directly fit on the outer side surface or top surface of the corner fitting 11, realizing uniform force transmission and expansion of the force-bearing surface, and avoiding local stress concentration or material fatigue failure caused by single-point connection.

[0051] Through this structural design, the setting of the connecting base 213 not only realizes the force sharing and stable support of the connecting structure, thus effectively dispersing the acting force in structure, avoiding stress concentration, and improving the anti-vibration performance and long-term fatigue durability of the system. At the same time, the connecting base 213 can also serve as an intermediate transition platform to provide a structural installation surface for subsequent addition of functional components such as anti-vibration structures and flexible gaskets.

[0052] The connecting base 213 in this embodiment can be made of rigid metal materials such as steel, aluminum alloy, etc., to enhance the assembly strength and reliability of long-term operation. In some implementation manners, a certain anti-slip structure such as anti-slip lines can be provided on the side of the connecting base 213 facing the corner fitting 11 to increase the friction between the two and prevent components such as the upper support member 22 from slipping or becoming unstable.

[0053] Based on the above embodiment, further, as Figure 4 shown, the first connecting portion 211 includes a base portion 2110 and a support portion 2111. Among them, the base portion 2110 is closer to the corresponding support member 22 than the support portion 2111, and is used for relatively connecting with the support member 22, preferably fixed by means such as bolt locking and plugging. When fixedly connected, at least partial contact can be formed between the support member 22 and the base portion 2110 to ensure the strength and rigidity of the structural connection.

[0054] The support portion 2111 is arranged between the base portion 2110 and the connecting base 213, so that at least one accommodating space is formed between the base portion 2110 and the connecting base 213. This accommodating space is mainly used for the storage of fasteners during the installation process. For example, when the support member 22 is connected to the base portion 2110 through fasteners, the installer can perform the fastening operation through this accommodating space, and at least part of the fasteners are located in this accommodating space, thus achieving the installation effect of structural embedding. It can be understood that this design not only improves the safety and installation convenience, but also helps to achieve a certain degree of dust and water protection functions, meeting the higher requirements for connection reliability and long-term stability in outdoor installation environments.

[0055] Optionally, the number of the supporting portions 2111 may be one or more, and can be specifically designed and optimized according to different structural strength requirements or spatial layouts. In the example shown in the drawings of the present application, two supporting portions 2111 are adopted, and the two supporting portions 2111 are arranged at intervals along the width direction of the base portion 2110, thereby forming a relatively symmetrical connection layout in terms of structure, improving the force balance and structural stability. However, in other embodiments, the supporting portions 2111 may also adopt forms such as an asymmetric arrangement or a grid-shaped strengthening structure, and can be specifically and diversely optimized and adjusted according to requirements such as installation working conditions, connection strength, and drainage paths, further enhancing the applicability and modular assembly ability.

[0056] In one embodiment, the second connecting portion 212 includes a fixing member 2121 and a limiting member 2122, and is used to realize a stable and detachable mechanical connection between the fixed bracket structure 2 and the container 1.

[0057] Wherein, one end of the fixing member 2121 is fixedly arranged on the main body structure of the fixing component 21, and is usually connected to the fixing component 21 by welding, riveting or integral molding to ensure the overall strength and rigidity during use. The other end of the fixing member 2121 is correspondingly inserted into the first preset interface 111 of the corner fitting 11 during the assembly process, and the limiting member 2122 is correspondingly inserted into the second preset interface 112 of the corner fitting 11 during the assembly process, and is detachably connected to the fixing member 2121 through a single fastener. Specifically, after the limiting member 2122 passes through the second preset interface 112, it can be connected to the through hole and other structures on the fixing member 2121 through a single fastener to form a locking relationship, preventing the fixing member 2121 from loosening, falling off or rotating and shifting during use after installation. The first connecting portion 211 is tenon-and-mortise inserted into the corner fitting 11 through the fixing member 2121, and then the limiting member 2122 and the fixing member 2121 are connected through a single fastener. The entire installation process is simple and efficient, and the single fastener also reduces the cost.

[0058] Furthermore, the first preset interface 111 and the second preset interface 112 can select standard orifices, slots or interface surfaces on the corner fitting 11, so that no additional processing and transformation of the container are required during the installation process, and it has good versatility and engineering adaptability.

[0059] It can be understood that with the setting of this embodiment, only a single fastener is required to realize the firm connection between the fixing component 21 and the corner fitting 11, which can effectively reduce the number of components, reduce the complexity of the installation operation, and at the same time ensure the connection strength and precision; and the limiting member 2122 and the fixing member 2121 can form a multi-directional limiting connection mode, effectively suppressing the structural displacement caused by factors such as wind load, vibration, thermal expansion and contraction, etc., and improving the reliability and durability of the overall connection.

[0060] It should be noted that the detachable connection method between the limiting member 2122 and the fixing member 2121 by a single fastener can be various to meet the structural strength requirements and installation convenience requirements of different application scenarios. In a preferred embodiment, the limiting member 2122 and the fixing member 2121 are fixed by connecting with a single bolt assembly. Specifically, the fixing member 2121 is provided with a perforation structure, and the limiting member 2122 is correspondingly provided with a through hole for the bolt to pass through. During the installation process, the fixing member 2121 is inserted into the first preset interface 111 on the container 1, the limiting member 2122 can pass through the second preset interface 112 on the container 1 and abut against the fixing member 2121. At this time, the perforation on the fixing member 2121 and the through hole on the limiting member 2122 are axially corresponding, and then the limiting member 2122 and the fixing member 2121 are tightly connected by a single bolt assembly, so as to realize the high-strength mechanical fixation between the fixing component 21 and the container 1.

[0061] In another embodiment, the fixing member 2121 is provided with a groove structure, and the limiting member 2122 is correspondingly provided with a clamping structure. During the installation process, the fixing member 2121 is inserted into the first preset interface 111 on the container 1, the limiting member 2122 passes through the second preset interface 112 on the container 1 and is clamped to the fixing member 2121, and then is tightly connected by a single bolt assembly, so as to realize the high-strength mechanical fixation between the fixing component 21 and the container 1. Through the bolt connection method, on the one hand, it can ensure a reliable connection state between the limiting member 2122 and the fixing member 2121, with good bearing capacity and shear strength, meeting the long-term stability requirements of the photovoltaic module due to external force factors such as wind load, snow load and vibration during outdoor operation; on the other hand, the bolt connection is a typical detachable connection structure, which is convenient for subsequent maintenance, replacement or structural adjustment.

[0062] Specifically, in an alternative embodiment, the mounting nut can be pre-fixed to the fixing member 2121 and cooperate with the opening on the fixing member 2121 to form a connection structure that cooperates with the limiting member 2122. During installation, only need to pass the bolt through the limiting member 2122 and this connection structure in sequence to complete the bolt fastening. Of course, in other alternative embodiments, the limiting member 2122 and the fixing member 2121 can also be assembled by means of snap connection, pin connection, etc., which are not limited here.

[0063] Optionally, the limiting member 2122 can be connected to the fixing member 2121 in a vertical or inclined posture. The installation position of the limiting member 2122 can be appropriately adjusted according to the actual use conditions, such as using an inclined angle to penetrate or providing multiple limiting hole positions for selection to meet the installation requirements of different types of container interface holes.

[0064] In one embodiment, based on the above embodiment, further, reference may be made to the attached drawings of the specification Figures 4 to 6 , the inside of the corner fitting 11 has a cavity, and both the first preset interface 111 and the second preset interface 112 are connected to the cavity, so as to cooperate with the fixing member 21 to complete a quick and stable connection.

[0065] Among them, the first preset interface 111 corresponds to the top surface direction of the container 1 (i.e., the upward opening of the corner fitting 11), and the second preset interface 112 corresponds to the side surface direction of the container 1.

[0066] During the installation process, the fixing member 2121 is inserted into the first preset interface 111 at the top of the container 1 and extends into the cavity inside the corner fitting 11; at the same time, the limiting member 2122 penetrates through the second preset interface 112 arranged laterally and is connected to the fixing member 2121 inside the cavity. Through the above structure, the fixing member 2121 forms a top plug-in connection with the first preset interface 111, and the limiting member 2122 forms a lateral limiting connection with the fixing member 2121, so as to cooperate to realize the spatial positioning and stable fixing of the fixing member 21.

[0067] Among them, the inner peripheral surface size of the first preset interface 111 matches the outer peripheral surface size of the fixing member 2121, so that when the fixing member 2121 is inserted into the first preset interface 111, its outer surface abuts against the hole wall of the first preset interface 111, ensuring the tightness of the cooperation and effectively restricting the displacement freedom of the fixing member 2121 in the horizontal direction; similarly, after the limiting member 2122 passes through the second preset interface 112 and extends into the cavity, a certain abutment is also formed between its outer surface and the second preset interface 112, thereby further restricting the movement freedom of the limiting member 2122 in the vertical direction; finally, the limiting member 2122 and the fixing member 2121 are connected by a single fastener, further restricting the relative displacement between the fixing member 2121 and the limiting member 2122, so as to effectively restrict the displacement freedom of the fixing member 21 in the horizontal direction and the vertical direction.

[0068] Furthermore, the cross-sectional shape of the first preset interface 111 and / or the second preset interface 112 may be a non-circular structure, such as an oval, a square, a rectangle, or a polygonal orifice. The corresponding structures of the fixing member 2121 and the limiting member 2122 are also set to a matching non-circular cross-sectional structure, so as to further restrict the circumferential rotational freedom of the fixing member 21 after the assembly is completed. Combining the above content, through the cooperation of the first preset interface 111 and the fixing member 2121, the cooperation of the second preset interface 112 and the limiting member 2122, and the cooperation of a single fastener with the limiting member 2122 and the fixing member 2121, the freedom of the fixing member 21 in the horizontal and vertical directions is restricted, so that the degrees of freedom of the overall structure in different directions are locked, and situations such as movement or swing will not occur, and thus it can maintain high stability during long-term operation.

[0069] In one embodiment, the limiting member 2122 includes a connecting body 21221 and a limiting baffle 21222. Among them, the connecting body 21221 is a tubular structure, and the limiting baffle 21222 is fixed to one end of the connecting body 21221 and serves as an end extension of the structure of the limiting member 2122.

[0070] During the actual installation process, when the fixing member 2121 is inserted into the first preset interface 111 of the container 1 and extends deep into the internal cavity of the corner fitting 11, the connecting body 21221 of the limiting member 2122 is inserted from the second preset interface 112 of the corner fitting 11 and extends into the internal cavity, and is mechanically connected to the fixing member 2121. At this time, the limiting baffle 21222 abuts and contacts the outer surface of the side where the second preset interface 112 is located.

[0071] It can be understood that through the setting in this embodiment, the limiting baffle 21222, as an end member of the connecting body 21221, on the one hand, its size is larger than the opening of the second preset interface 112. Therefore, after the connecting body 21221 is completely inserted, it can prevent the connecting body 21221 from continuing to slide inward, thereby realizing the axial stop of the limiting member 2122 in the insertion direction. On the other hand, the limiting baffle 21222 covers the second preset interface 112, effectively blocking foreign matters such as dust and water vapor from entering the internal cavity of the corner fitting 11, which is beneficial to the long-term stable operation of the system under complex outdoor climate conditions.

[0072] In addition, the structural form of the limit baffle 21222 can be diversely designed according to actual assembly requirements. For example, in the form shown in the attached drawings of this application, the limit baffle 21222 adopts a flat sheet-like structure to cover the edge of the interface, or is provided with a sealing gasket to enhance its sealing performance. Preferably, the limit baffle 21222 and the connection main body 21221 adopt an integrally formed structure to ensure the connection strength and overall stability. Of course, the limit baffle 21222 and the connection main body 21221 can also be assembled into one body by welding, screwing or clamping methods.

[0073] In one embodiment, reference can be made to the attached drawings of the specification Figure 7 , each support member 22 is provided with at least two cantilever ends 221 arranged at intervals in the height direction, and the extending directions of the respective cantilever ends 221 are perpendicular to the central axis of the corresponding support member 22, forming a structure form that spreads outwards.

[0074] In this embodiment, a groove-like structure with an outward opening is formed by the common enclosure of two of the cantilever ends 221 and the support member 22. This groove-like structure constitutes the installation part 220 of the support member 22 for installing and fixing the photovoltaic module. Specifically, the edge part of the photovoltaic module can be inserted and embedded in this groove-like structure, and the effective clamping of the edge of the photovoltaic module is realized by means of the cantilever ends 221, so as to achieve the effect of mechanical positioning and preliminary fixing of the photovoltaic module without additional fasteners.

[0075] It can be understood that through the setting of this embodiment, the double cantilever ends 221 form double limits on the module in the up and down directions, which can effectively resist the shedding and loosening of the module under the action of wind load or gravity, and improve the overall stability and safety of the structural system. In addition, when installing the photovoltaic module, it only needs to insert the module into the groove-like installation part 220 from one side in the length direction of the support member 22, which can improve the on-site construction efficiency.

[0076] Optionally, the groove-like structure can adopt a rounded corner transition or be provided with a buffer material inside to avoid damage to the edge of the module glass caused by mechanical clamping and improve the operation reliability of the module.

[0077] In practical applications, each support member 22 can fix one end of a photovoltaic module, that is, a photovoltaic module can be fixedly connected by at least two support members 22 arranged on the opposite edges of the container 1 respectively.

[0078] For example, during the installation of a photovoltaic module, two support members 22 can be first selected and fixed to the corresponding corner fittings 11 on the container 1 respectively, so as to install the two support members 22 on the opposite sides of the top plate of the container, preferably on the opposite sides in the width direction of the top plate of the container; subsequently, the photovoltaic module is inserted into the two oppositely arranged groove-shaped mounting parts 220 along one side in the length direction of the support member 22, so that the opposite side edges of the photovoltaic module are respectively clamped into the groove-shaped structures of the two support members 22, realizing the clamping installation of the photovoltaic module by the two support members 22 on both sides, thereby completing the overall stable positioning of the module.

[0079] In one embodiment, based on the above embodiment, further, the fixed support structure 2 further includes at least one spacer 51. At the same time, at least two cantilever ends 221 include a cantilever 2211 and a second cantilever 2212. After the support member 22 is installed on the container 1 through the fixing member 21, the first cantilever 2211 and the second cantilever 2212 are respectively located at different horizontal height positions, wherein the height of the first cantilever 2211 is higher than that of the second cantilever 2212.

[0080] Wherein, at least one spacer 51 can be arranged on the side of the first cantilever 2211 and / or the second cantilever 2212 close to each other. For example, a spacer 51 is arranged on the side of the second cantilever 2212 close to the first cantilever 2211, as Figure 7 and Figure 8 shown. When multiple photovoltaic modules are respectively installed side by side on the support member 22, the spacer 51 is arranged between two adjacent photovoltaic modules, playing a role of limiting and positioning and maintaining the spacing, so that a preset gap distance is maintained between the two photovoltaic modules, thereby forming a ventilation channel, effectively improving the heat dissipation capacity and operation stability of the entire photovoltaic array.

[0081] Similarly, arranging a spacer 51 on the side of the first cantilever 2211 facing the second cantilever 2212 can also play a similar role. The above two setting methods can be independently set or can also be both available, so as to be flexibly selected according to the actual arrangement mode of the photovoltaic modules, ventilation requirements or the installation orientation of the support member 22, so as to achieve the best structural adaptation and thermal management control.

[0082] It can be understood that in this embodiment, by arranging the spacer 51 to generate a ventilation spacing between the components, an air flow channel can be formed, improving the air convection efficiency, effectively reducing the working temperature of the photovoltaic module, and improving its power output efficiency; on the other hand, by arranging the spacer 51 between two adjacent photovoltaic modules, the spacing of the photovoltaic modules is made uniform, improving the modularity and aesthetics of the system.

[0083] It should be noted that the structural form of the isolation member 51 can be diversified, for example, it can be a rubber block or a plastic block, and its size, shape, material and other parameters can be customized according to factors such as the photovoltaic module spacing requirements, the operating environment temperature and the module shape.

[0084] Furthermore, if Figures 7 to 9 As shown, the isolation member 51 and its corresponding cantilever end 221 are slidably connected. Specifically, the corresponding cantilever end 221 is provided with a slide groove 50 extending along its length direction. The slide groove 50 is used to limit and guide the installation direction of the isolation member 51, so that the isolation member 51 can be slidably adjusted in the slide groove 50 along the length direction of the support member 22.

[0085] In actual operation, the isolation member 51 can be installed simultaneously during the installation process of the photovoltaic components. For example, a group of photovoltaic components can be installed first, and then one or several isolation members 51 can be slid in after the installation is completed, so that isolation can be naturally formed between the photovoltaic component and the next group of photovoltaic components. When the next group of photovoltaic components is installed, the corresponding thrust applied by the outside world can also assist the isolation member 51 to move into place.

[0086] In addition, a corresponding anti-slip structure is provided between the chute 50 and the isolating member 51 to prevent the isolating member 51 from slipping out of the chute 50. For example, in one embodiment, a flange structure is provided at the bottom of the isolating member 51. After being inserted into the chute 50, the flange structure forms a limit lock with a predetermined latching portion inside the chute 50, preventing the isolating member 51 from slipping out of the chute 50, thereby ensuring the stability and reliability of the device during operation.

[0087] At the same time, you can also refer to the instructions attached Figure 7 The chute 50 is configured as a dovetail groove, and the bottom profile of the isolator 51 is also adapted to the profile of the dovetail groove. Specifically, the upper surface (opening) of the chute 50 is narrow, and becomes wider as it goes deeper, and the two side edges are oblique straight lines (forming a trapezoidal or approximately triangular profile).

[0088] During the installation process, the bottom of the isolation member 51 slides into one end of the dovetail groove and slides along the length direction of the cantilever end 221 to the target installation position. Due to the self-locking characteristics of the dovetail groove structure, it cannot be dislodged from the vertical direction or non-axial direction, thereby significantly improving the anti-pullout ability and structural reliability after installation, thereby preventing the isolation member 51 from falling off, and can provide certain support and stability through the wider bottom of the dovetail groove.

[0089] In one embodiment, Figure 7As shown, each support member 22 has at least three cantilever ends 221. In the height direction, the two upper cantilever ends 221 are spaced apart to form the above-mentioned mounting portion 220, thereby forming clamping and limiting of the photovoltaic module. The lowermost cantilever end 221 is used to connect with the corresponding fixing member 21 to achieve relative fixation between the support member 22 and the container 1.

[0090] It can be understood that by providing multiple cantilever ends 221 with different heights on one support member 22, the installation structure of the photovoltaic module and the connection structure corresponding to the container 1 can be reasonably distributed within a limited space, reducing the number of components and simplifying the system structure.

[0091] Optionally, the bottom cantilever end 221 is provided with connection structures such as bolt holes and clamping ends, which are convenient for fixing with the fixing member 21 installed on the container.

[0092] Furthermore, the cantilever ends 221 are symmetrically distributed on both sides of the support member 22 along the central axis of the support member 22. That is, on each cross-section of the support member 22, with its central axis as the axis of symmetry, corresponding numbers and positions of cantilever ends 221 are respectively arranged on its left and right sides, making the support member 22 as a whole present a left-right symmetric structure. Furthermore, each fixing member 21 can be simultaneously connected to the corresponding two cantilever ends 221 at the bottom of the support member 22 to improve the structural stability and assembly reliability.

[0093] It can be understood that by connecting two bottom cantilever ends 221 on both sides of the support member 22 with one fixing member 21, a structure similar to "double-point anchoring" is formed. The connection surface is larger, the force is more uniform, effectively reducing local stress concentration that may occur in single-point connection or structural offset caused by torque imbalance, and improving the overall stability of the entire support assembly.

[0094] Furthermore, the support member 22 is in a hollow tubular structure, that is, the support member 22 forms a closed or partially closed hollow cavity in the cross-section to fully control the self-weight of the structure and the material utilization rate. At least one reinforcing rib 23 is fixedly arranged in the inner cavity of the support member 22 to further enhance the mechanical strength of the support member 22 during actual use.

[0095] Specifically, in the height direction of the overall structure, the reinforcing rib 23 is located between the mounting portion 220 and the fixing member 21, that is, the reinforcing rib 23 is arranged at the middle position between the mounting portion 220 connecting the photovoltaic module and the fixed area at the bottom of the support member 22, so as to accurately cover the area where the maximum bending moment may occur, and specifically enhance the structural stiffness and bearing capacity.

[0096] It should be noted that the reinforcing rib 23 can be arranged in various forms, including but not limited to: being set as a transverse partition penetrating the inner cavity, with both ends welded or riveted to the inner wall of the support member 22; or it can be a cross-shaped or grid-shaped reinforcing structure, forming a closed or semi-closed unit with the inner cavity of the support member 22, thereby further improving the buckling stability.

[0097] It can be understood that although the hollow structure is light in weight, the wall thickness of the main body is limited, and it is easy to bend under concentrated loads. By arranging the reinforcing rib 23, a "rigid framework" is formed locally to improve the overall bending stiffness of the structure; in addition, during installation, operation, etc., the photovoltaic module will be subjected to repeated loads such as wind loads and thermal deformation. The reinforcing rib 23 helps to limit the displacement and deformation of the support member 22 and extend its fatigue life.

[0098] In one embodiment, as Figure 7 and Figure 9 shown, the support member 22 is provided with a groove portion 24 on the side facing the fixing member 21. The groove portion 24 extends along the length direction of the support member 22 to form a space for embedding a fastening member (such as the nut 25 described later).

[0099] More specifically, the groove portion 24 is provided with an inwardly retracted limiting edge 241 at the open end on the side away from its bottom, that is, a structure is set or processed on the opening edge of the groove portion 24 to retract inwardly towards the cavity of the groove, forming a pair of inwardly facing limiting edges 241. This structure is similar to the "T-shaped groove" structure in industrial aluminum profiles, making the connecting member embedded therein slidable longitudinally but restricted in the vertical direction.

[0100] As Figure 9 shown, the fixed bracket structure further includes a nut 25 and a connecting bolt 26 that cooperates with the nut 25. During actual installation, the operator can first slide the nut 25 into the groove portion 24 from one side in the length direction, and after it is in the target position, the connecting bolt 26 passes through the preset installation hole on the fixing member 21 and is tightened in cooperation with the nut 25 from the opening of the groove portion 24, thereby completing the connection between the support member 22 and the fixing member 21.

[0101] Among them, after the support member 22 and the fixing member 21 are relatively fixed, the nut 25 is placed in the groove portion 24, so that the nut 25 can abut against the limiting edge 241 and / or the bottom of the groove portion 24, and specifically, the following two contact states can be formed: In the first state, the nut 25 is in contact with the bottom of the groove portion 24 and the limiting flanges 241 on its left and right sides simultaneously. When the connecting bolt 26 is tightened, the force received by the support member 22 can be directly transmitted to the fixing member 21 through the nut 25, and further transmitted to the container 1 by the fixing member 21, thereby dispersing the force on the support member 22. At the same time, the outer side surface of the nut 25 abuts against the limiting flange 241 to form a limit, preventing the nut 25 from falling off the groove portion 24.

[0102] In the second state, the top of the nut 25 does not directly abut against the bottom of the groove portion 24, but the bottom surface of the nut 25 abuts against the limiting flanges 241 on its left and right sides respectively. In this state, when the connecting bolt 26 is tightened, the axial force directly acts on the limiting flange 241 through the outer periphery of the nut 25, and the force is transmitted to the two side walls of the groove portion 24 by the limiting flange 241 and finally transmitted to the structural body of the support member 22, thereby realizing the structural locking between the support member 22 and the fixing member 21.

[0103] Moreover, although the nut 25 and the bottom of the groove portion 24 do not form an abutment in the vertical direction temporarily, when the bottom of the support member 22 continues to deform due to factors such as load in the future, the top of the nut 25 will first contact the bottom of the groove portion 24, thereby playing an "active top" role to prevent the bottom from further sinking or tearing.

[0104] In one embodiment, the fixing bracket structure 2 includes two support members 22 and four fixing members 21, which are cooperatively installed on the corner fittings 11 at the four corners of the container 1. Specifically, both ends of each support member 22 are respectively connected to the corresponding corner fittings 11 through the fixing members 21, so that the two support members 22 are respectively arranged on two opposite sides of the container 1.

[0105] Furthermore, as Figure 2 shown, the fixing bracket structure 2 is further provided with two component baffles 27, which are respectively installed on the other two opposite sides of the container 1. Both ends of each component baffle 27 are respectively connected to different support members 22, that is: the component baffle 27 straddles between the two support members 22 and is fixed, thereby forming a complete boundary surrounding the periphery of the photovoltaic module. After installation, the photovoltaic module is limited within the area defined by the support member 22 and the component baffle 27. Through the cooperation of the component edge and the support member 22, a closed rigid frame is formed, which ensures the installation reliability and safety of the photovoltaic module to a certain extent.

[0106] In specific implementation, please refer to the attached Figure 3 to the specification. The component baffle 27 is set in a structural form similar to an L-shaped steel, having two mutually perpendicular sides to respectively realize the abutment limit of the photovoltaic module and the structural connection with the support member 22.

[0107] Among them, the first side 271 is set vertically and is close to the edge side of the photovoltaic module, which is used to block and limit the photovoltaic module after installation to prevent the module from sliding or dislocating laterally; the second side 272 is set horizontally and is connected and fixed to the corresponding position of the support member 22 (for example, the cantilever end 221 in the above embodiment), such as bolt fixing.

[0108] Of course, in other embodiments, the component baffle 27 can also be set to other structural forms, such as a rod-shaped structure or a tubular structure, as long as it can form a fixed connection with the support member 22 and can abut and limit the side of the photovoltaic component.

[0109] In one embodiment, Figure 10 As shown, the tracking bracket structure 3 includes a driving device 32 and a main shaft 31. The driving device 32 and at least part of the main shaft 31 are arranged inside the container 1. The main shaft 31 runs from the inside to the outside of the container 1. The driving device 32 is connected to the main shaft 31 in a transmission manner. The second photovoltaic component 42 is installed on the main shaft 31. The driving device 32 can drive the main shaft 31 to rotate, so as to drive the second photovoltaic component 42 to rotate with the sun.

[0110] It can be understood that the drive device 32 is fixedly installed inside the container 1, and the main shaft 31 and the drive device 32 are connected by transmission, which can generally be achieved by gear meshing, coupling or sprocket structure. In this embodiment, the specific method of transmission connection is not limited. In specific implementation, it can be selected according to specific needs to ensure that high and stable transmission efficiency can be maintained under different power requirements or torque transmission scenarios.

[0111] Moreover, it can be seen that in this embodiment, the driving device 32 is arranged inside the container 1, which can effectively isolate adverse environmental factors such as wind, rain, dust, etc., extend the service life, and at the same time simplify the external structure design to avoid affecting the aesthetics and maintenance convenience of the overall structure; in addition, the solid box structure of the container 1 itself replaces part of the columns, simplifies the structure of the photovoltaic bracket, and saves costs.

[0112] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred implementations of the present application. It should be noted that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application, and these improvements and modifications should also be considered as the scope of protection of the present application.
