Description

Technical Field

[0002] When constructing a photovoltaic power plant, the installation efficiency of the photovoltaic support structure and various components is crucial, as it directly affects the overall construction progress of the photovoltaic power generation system.

[0003] Currently, conventional photovoltaic bracket and module installation mainly relies on the cooperation of clamping blocks and bolts for fixation. However, this method has some problems. On the one hand, the clamping block structure is complex, the processing procedures are complicated and difficult, and the core bolt tightening process is not omitted. The bolt tightening process is cumbersome, costly and inefficient in high-altitude assembly operations. On the other hand, its fixing method relies on the friction between the spring clips and the hooks of the modules and purlins, which can easily lead to module detachment due to friction failure.

[0067] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0068] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0069] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0070] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0071] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0072] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0073] See Figure 1 At least one embodiment of this application provides a photovoltaic mounting structure 1000. The photovoltaic mounting structure 1000 is used to mount a photovoltaic bracket 2000 and a purlin 3000. The photovoltaic mounting structure 1000 includes a frame assembly 100 and a clamping block assembly 200. The frame assembly 100 includes a first frame 110 and a second frame 120, which are respectively mounted at both ends of the photovoltaic bracket 2000. The clamping block assembly 200 includes a first clamping block 210 and a second clamping block 220. The first clamping block 210 is used to engage with the first frame 110, and the second clamping block 220 is used to engage with the second frame 120. The side of the first clamping block 210 facing away from the first frame 110 is used to engage with the side of the second clamping block 220 facing away from the second frame 120. The first clamping block 210 and the second clamping block 220 are respectively used to engage with the purlin 3000.

[0074] According to the photovoltaic installation structure 1000 of this application embodiment, the first clamping block 210 is snapped into the first frame 110, the second clamping block 220 is snapped into the second frame 120, the first clamping block 210 and the second clamping block 220 are snapped into each other, and the first clamping block 210 and the second clamping block 220 are respectively snapped into the purlin 3000. No additional consumables such as bolts and nuts are required throughout the process, resulting in low cost. Furthermore, compared to the bolted connections of traditional technologies, the clamping block assembly 200 of this application only requires alignment and pressing to achieve snap-fit, simplifying installation and effectively improving installation efficiency. In addition, through multiple snap-fit ​​structures, the photovoltaic installation structure 1000 can bear loads in multiple directions, significantly improving its resistance to deformation.

[0075] See Figure 2 In some embodiments, the side of the first pressing block 210 opposite to the first frame 110 and the side of the second pressing block 220 opposite to the second frame 120 are engaged along a first direction. The first pressing block 210 is engaged with the purlin 3000 along the first direction, and the second pressing block 220 is engaged with the purlin 3000 along the first direction. When the first frame 110 and the second frame 120 are installed on the photovoltaic bracket 2000, and the first pressing block 210 is engaged with the first frame 110 and the second pressing block 220 is engaged with the second frame 120, when two adjacent photovoltaic brackets 2000 are engaged with the purlin 3000 through the first pressing block 210 and the second pressing block 220 respectively, the first pressing block 210 and the second pressing block 220 are engaged simultaneously. In some embodiments, the first direction is the Z direction in the figure, that is, the vertical direction.

[0076] Specifically, the engagement of the first pressing block 210 with the second pressing block 220, the engagement of the first pressing block 210 with the purlin 3000, and the engagement of the second pressing block 220 with the purlin 3000 are all completed along the first direction. One operation can simultaneously complete three engagements, connecting adjacent photovoltaic brackets 2000 and engaging adjacent photovoltaic brackets 2000 with the purlin 3000.

[0077] With the above settings, frequent adjustments to the operating angle are unnecessary, allowing installers to quickly complete multiple connections and improving installation efficiency. Furthermore, the vertical direction is where the photovoltaic equipment bears the main loads, such as the weight of the photovoltaic panels. The connections between the first pressure block 210 and the second pressure block 220, and between the first pressure block 210, the second pressure block 220, and the purlin 3000 are all along the vertical direction, directly transferring the load to the purlin 3000 and preventing loosening due to inconsistencies between the direction of force and the connection direction.

[0078] In some embodiments, a first frame 110 is mounted on one end of the photovoltaic bracket 2000 along a second direction, and a first clamping block 210 is engaged with the first frame 110 along the second direction. A second frame 120 is mounted on the other end of the photovoltaic bracket 2000 along a third direction, and a second clamping block 220 is engaged with the second frame 120 along the third direction. Both the second and third directions are parallel to the surface of the photovoltaic bracket 2000, and the second and third directions are opposite. In some embodiments, the second direction is the X direction in the figure, and the third direction is the Y direction in the figure.

[0079] Specifically, the snap-fit ​​direction of the first clamping block 210 and the first frame 110 matches the installation direction of the first frame 110 on the photovoltaic bracket 2000. This ensures that the direction of force applied when the first clamping block 210 and the first frame 110 snap-fit ​​together is consistent with the direction of force applied when the first frame 110 is installed on the photovoltaic bracket 2000, preventing loosening due to directional misalignment after snap-fitting and reinforcing the connection between the first frame 110 and the photovoltaic bracket 2000. Similarly, the snap-fit ​​direction of the second clamping block 220 and the second frame 120 matches the installation direction of the second frame 120 on the photovoltaic bracket 2000. This further reinforces the connection between the second frame 120 and the photovoltaic bracket 2000.

[0080] With the above settings, the first frame 110 is installed along the X direction and the first pressure block 210 is engaged along the X direction, which is equivalent to forming a constraint from the right end of the photovoltaic bracket 2000 to the right; the second frame 120 is installed along the opposite Y direction and the second pressure block 220 is engaged along the Y direction, which is equivalent to forming a constraint from the left end of the bracket to the left; the two together form a bidirectional limit, which firmly fixes both ends of the photovoltaic bracket 2000 in the preset position, preventing the photovoltaic bracket 2000 from moving along the width direction and greatly improving the overall stability of the structure.

[0081] In addition, in this embodiment, the frame assembly 100 and the pressure block assembly 200 can transmit the external force along the width direction of the photovoltaic support 2000 to the pressure block assembly 200 through the frame assembly 100, and then to the purlin 3000 through the pressure block assembly 200. This allows the external force to be dispersed to a certain extent at the connection points between the first pressure block 210, the second pressure block 220 and the purlin 3000, avoiding local stress concentration and improving the structural load-bearing capacity.

[0082] Furthermore, since the second and third directions are parallel to the width of the photovoltaic bracket 2000, the frame component 100 and the pressure block component 200 will not exert additional force on the photovoltaic bracket 2000 in the direction perpendicular to the width when they are snapped together. This can prevent the photovoltaic bracket 2000 from bending or deforming due to the force direction being inconsistent with its main bearing direction, and can effectively extend the service life of the photovoltaic bracket 2000.

[0083] In some embodiments, the first direction is perpendicular to the second direction and also perpendicular to the third direction. That is, the X and Y directions in the figure are both horizontal directions, and both the X and Y directions are perpendicular to the Z direction.

[0084] See Figure 2 and Figure 3In some embodiments, the first pressing block 210 includes a first connecting portion 211 and a first extension portion 212. The first connecting portion 211 is provided with a first edge-locking component 2111, which is used to engage with the first frame 110. The first extension portion 212 is fixedly connected to the first connecting portion 211, and the first extension portion 212 is provided with a first locking component 2121, which is used to engage with the purlin 3000.

[0085] In some embodiments, the first connecting portion 211 extends along a first direction, and the first extension portion 212 is connected to the bottom end of the first connecting portion 211 and extends along a second direction. The first connecting portion 211 and the first extension portion 212 are L-shaped.

[0086] In some embodiments, the first connecting portion 211 and the first extension portion 212 can be integrally formed, reducing the number of parts and assembly steps, and lowering processing and installation costs.

[0087] In some embodiments, the first locking assembly 2111 includes a first locking hook 2111a and a second locking hook 2111b fixedly disposed on the side of the first connecting portion 211 near the first frame 110, the first locking hook 2111a and the second locking hook 2111b being arranged sequentially along a first direction. Correspondingly, the side of the first frame 110 near the first pressing block 210 is provided with a first locking portion 112 and a second locking portion 113, the first locking portion 112 and the second locking portion 113 being arranged sequentially along the first direction. The installer takes the first pressing block 210, aligns it with the first frame 110, and pushes the first pressing block 210 along a second direction, so that the first locking hook 2111a of the first pressing block 210 engages with the first locking portion 112 of the first frame 110, and at the same time, the second locking hook 2111b of the first pressing block 210 engages with the second locking portion 113 of the first frame 110, thereby realizing the engagement between the first pressing block 210 and the first frame 110.

[0088] In some embodiments, the first snap-fit ​​assembly 2121 includes a first snap-fit ​​hook 2121a, which is fixedly connected to the first extension 212 and is used to snap-fit ​​with the purlin 3000.

[0089] See Figure 2 and Figure 4 The second pressing block 220 includes a second connecting portion 221 and a second extension portion 222. The second connecting portion 221 is provided with a second edge-locking component 2211, which is used to engage with the second frame 120. The second extension portion 222 is fixedly connected to the second connecting portion 221, and the second extension portion 222 is provided with a second locking component 2221, which is used to engage with the purlin 3000.

[0090] In some embodiments, the second connecting portion 221 extends along a first direction, and the second extension portion 222 is connected to the bottom end of the second connecting portion 221 and extends along a third direction. The second connecting portion 221 and the second extension portion 222 are L-shaped.

[0091] In some embodiments, the second connecting portion 221 and the second extension portion 222 can be integrally formed, reducing the number of parts and assembly steps, and lowering processing and installation costs.

[0092] In some embodiments, the second locking assembly 2211 includes a third locking hook 2211a and a fourth locking hook 2211b fixedly disposed on the side of the second connecting portion 221 near the second frame 120, the third locking hook 2211a and the fourth locking hook 2211b being arranged sequentially along a first direction. Correspondingly, the side of the second frame 120 near the second pressing block 220 is provided with a third locking portion 122 and a fourth locking portion 123, the third locking portion 122 and the fourth locking portion 123 being arranged sequentially along the first direction. The installer takes the second pressing block 220, aligns it with the second frame 120, and pushes the second pressing block 220 along a third direction, so that the third locking hook 2211a of the second pressing block 220 engages with the third locking portion 122 of the second frame 120, while the fourth locking hook 2211b of the first pressing block 210 engages with the fourth locking portion 123 of the second frame 120, thereby realizing the engagement between the second pressing block 220 and the second frame 120.

[0093] In some embodiments, the second snap-fit ​​assembly 2221 includes a second snap-fit ​​hook 2221a, which is fixedly connected to the second extension 222 and is used to snap-fit ​​with the purlin 3000.

[0094] See Figure 3 and Figure 4 In some embodiments, the first connecting portion 211 has a first assembly portion 2112 on the side opposite to the first edge-locking assembly 2111, and the second connecting portion 221 has a second assembly portion 2212 on the side opposite to the second edge-locking assembly 2211. (Combined with...) Figure 1 and Figure 2 The first assembly part 2112 is used to engage with the second assembly part 2212.

[0095] In some embodiments, the first assembly portion 2112 includes a first assembly connecting plate 2112a and a first assembly connecting hook 2112b. The first assembly connecting plate 2112a is fixedly disposed on the side of the first connecting portion 211 away from the first frame 110, and the first assembly connecting hook 2112b is fixedly disposed on the first assembly connecting plate 2112a. The second assembly portion 2212 includes a second assembly connecting plate 2212a and a second assembly connecting hook 2212b. The second assembly connecting plate 2212a is fixedly disposed on the side of the second connecting portion 221 away from the second frame 120, and the second assembly connecting hook 2212b is fixedly disposed on the second assembly connecting plate 2212a. Furthermore, the second assembly connecting plate 2212a is located above the first assembly connecting plate 2112a, that is, the second assembly connecting plate 2212a and the first assembly connecting plate 2112a are arranged sequentially along a first direction. The installer takes the second pressure block 220, aligns its second combined connecting part with the first combined connecting part of the first pressure block 210, and pushes the second pressure block 220 along the first direction, causing its second combined connecting hook 2212b to engage with the first combined connecting hook 2112b of the first pressure block 210, thus achieving the engagement of the first and second pressure blocks 210. The second combined connecting plate 2212a is located above the first combined connecting plate 2112a. During installation, simply pushing the second pressure block 220 along the first direction allows the second combined connecting hook 2212b to precisely engage with the first combined connecting hook 2112b. This eliminates the need for multi-directional angle adjustments, simplifying operation and increasing fault tolerance, reducing rework. Furthermore, the directional engagement method prevents loosening due to external force after engagement, improving connection reliability. In addition, the first assembly 2112 and the second assembly 2212 are integrated on one side of the first connecting part 211 and the second connecting part 221, respectively, without the need for additional independent connecting parts. While realizing the interlocking function of the pressure block, it does not occupy the extra installation space between the photovoltaic bracket 2000 and the purlin 3000, adapting to the space requirements of different installation scenarios.

[0096] Through the above configuration, the first assembly 2112 of the first connecting part 211 and the second assembly 2212 of the second connecting part 221 are engaged, clarifying the connection method between the first pressure block 210 and the second pressure block 220 of adjacent photovoltaic brackets 2000. This allows the originally independent first pressure block 210 and second pressure block 220 to form a stable connection, preventing lateral misalignment after the installation of adjacent photovoltaic brackets 2000 and ensuring the neatness and structural continuity of the photovoltaic equipment. Simultaneously, when the photovoltaic equipment bears a load, the engagement structure of the first assembly 2112 and the second assembly 2212 can evenly transfer the load of the adjacent photovoltaic brackets 2000 to the pressure block assemblies 200 on both sides and the purlins 3000 below, avoiding localized stress concentration and improving the overall load-bearing capacity.

[0097] It is understandable that the edges of photovoltaic equipment are structurally weak points, prone to warping or loosening due to uneven load distribution. To address this issue, a third pressure block 230 is installed at the convenient location of the photovoltaic equipment. For details, please refer to... Figure 5 In some embodiments, the clamping block assembly 200 further includes a third clamping block 230, which is disposed at the edge of the photovoltaic device and used to engage with the first frame 110 or the second frame 120. The third clamping block 230 is also used to engage with the purlin 3000. The third clamping block 230, disposed at the edge of the photovoltaic device, secures the edge area of ​​the photovoltaic device by engaging with the first frame 110 or the second frame 120 and with the purlin 3000, preventing single-point failure at the edge from causing overall structural instability. While the first clamping block 210 and the second clamping block 220 handle the conventional connections at both ends of the photovoltaic bracket 2000, the third clamping block 230 can flexibly engage with the first frame 110 or the second frame 120, adapting to different edge connection scenarios of the photovoltaic device. The load borne by the edge area of ​​the photovoltaic device can be directly transferred to the purlin 3000 through the third clamping block 230, preventing load accumulation at the edge from causing deformation of the frame assembly 100 and improving the overall load-bearing capacity of the photovoltaic device.

[0098] See Figure 5 and Figure 6 In some embodiments, the third pressing block 230 includes a third connecting portion 231 and a third extension portion 232. The third connecting portion 231 is provided with a third edge-locking component 2311, which is used to engage with the first frame 110 or the second frame 120. The third extension portion 232 is fixedly connected to the third connecting portion 231, and the third extension portion 232 is provided with a third locking component 2321, which is used to engage with the purlin 3000.

[0099] In some embodiments, the third connecting portion 231 extends along a first direction, and the third extension portion 232 is connected to the bottom end of the third connecting portion 231 and extends along a second or third direction. The third connecting portion 231 and the third extension portion 232 are L-shaped.

[0100] In some embodiments, the third connecting portion 231 and the third extension portion 232 can be integrally formed, reducing the number of parts and assembly steps, and lowering processing and installation costs.

[0101] In some embodiments, the third edge-locking assembly 2311 includes a fifth edge-locking hook 2311a and a sixth edge-locking hook 2311b fixedly disposed on the side of the third connecting portion 231 near the first frame 110 or the second frame 120. The fifth edge-locking hook 2311a and the sixth edge-locking hook 2311b are arranged sequentially along a first direction. An installer takes the third pressure block 230, aligns it with the first frame 110 located in the edge area of ​​the photovoltaic device, and pushes the third pressure block 230 along a second direction, causing the fifth edge-locking hook 2311a of the third pressure block 230 to engage with the first edge-locking portion 112 of the first frame 110, while the sixth edge-locking hook 2311b of the first pressure block 230 engages with the second edge-locking portion 113 of the first frame 110, thus achieving engagement between the third pressure block 230 and the first frame 110. Engaging the third pressure block 230 with the second frame 120 is similar to the above description and will not be repeated here.

[0102] In some embodiments, the third locking assembly 2321 includes a third locking hook 2321a and a fourth locking hook 2321b, which are fixedly connected to the third extension 232, and are used to engage with the purlin 3000.

[0103] See Figure 7 In some embodiments, the purlin 3000 is provided with an opening 3300, and a first mounting portion 3100 and a second mounting portion 3200 are provided on both sides of the opening 3300. Combined with... Figure 1 The first locking part 3100 is used to engage with the first pressing block 210, and the second locking part 3200 is used to engage with the second pressing block 220. The first locking part 3100 and the second locking part 3200 are used to engage with the third pressing block 230.

[0104] Specifically, the purlin 3000 is U-shaped, and the opening 3300 is located at the top center of the purlin 3000.

[0105] When the purlin 3000 is used to connect to the photovoltaic bracket 2000 at a non-edge location of the photovoltaic equipment, the installer removes the first pressure block 210 and other parts connected to the first pressure block 210, so that the first locking hook 2121a extends into the purlin 3000 through the opening 3300 along the first direction until the first locking hook 2121a engages with the first locking part 3100. The first locking part 3100 can engage with the first locking hook 2121a of the first pressure block 210, and the second locking part 3200 can engage with the second locking hook 2221a on the second pressure block 220. The installer removes the second pressure block 220 and other parts connected to it, causing the second locking hook 2221a to extend into the purlin 3000 through the opening 3300 along the first direction until it engages with the second locking part 3200. Simultaneously, the second combined connecting hook 2212b on the second pressure block 220 engages with the first combined connecting hook 2112b on the first pressure block 210. The first locking hook 2121a and the second locking hook 2221a are arranged opposite to each other, and correspondingly, the first locking part 3100 and the second locking part 3200 are arranged opposite to each other, forming a reverse engagement constraint.

[0106] When the purlin 3000 is used to connect to the photovoltaic bracket 2000 at the edge of the photovoltaic equipment, the installer removes the third clamping block 230 and other parts connected to the third clamping block 230, allowing the third and fourth clamping hooks 2321a and 2321b to extend into the purlin 3000 through the opening 3300 in the first direction, until the third clamping hook 2321a engages with the first clamping part 3100 and the fourth clamping hook 2321b engages with the second clamping part 3200. The third and fourth clamping hooks 2321a and 2321b are arranged oppositely, forming a reverse interlocking constraint. The double clamping points of the third clamping block 230 can distribute the concentrated load to the two clamping positions of the purlin 3000, avoiding clamping block breakage or purlin 3000 deformation due to overload at a single clamping point.

[0107] With the above configuration, the first clamping portion 3100 and the second clamping portion 3200 on both sides of the opening 3300 of the purlin 3000 can simultaneously accommodate the clamping requirements of the first pressure block 210, the second pressure block 220, and the third pressure block 230. This eliminates the need for separate connection structures for different pressure blocks, reduces limitations on the processing types of the purlin 3000 and the compatibility with the pressure blocks, and lowers the complexity of production and installation. The opening 3300 and the clamping portions provide a clear positioning reference for the pressure blocks. During installation, simply align the corresponding clamping component of the corresponding pressure block with the opening 3300 of the purlin 3000; there is no need to repeatedly adjust the relative position of a pressure block and the purlin 3000, improving installation accuracy and efficiency and reducing misalignment and rework.

[0108] It is understood that in some embodiments, the first pressure block 210 and the second pressure block 220 located in the middle of the photovoltaic device, i.e., the middle pressure block and the purlin 3000, are single-clamp nodes; the third pressure block 230 located at the edge of the photovoltaic device, and the purlin 3000, are double-clamp nodes. The middle area of ​​the photovoltaic device is more evenly loaded, and the adjacent peripheral supports can work together to distribute the load. The single-clamp nodes of the first pressure block 210, the second pressure block 220, and the purlin 3000 can meet the requirements of foundation fixing and load transfer, avoiding material waste caused by over-design. The edge area of ​​the photovoltaic device is a weak point, without the cooperation of adjacent supports, and is susceptible to concentrated load impacts such as strong winds and snow accumulation. The double-clamp nodes of the third pressure block 230 can form a double constraint, greatly improving the edge's resistance to deformation and loosening, and realizing the differentiated load-bearing design of the photovoltaic device.

[0109] In addition, the middle area pressure block of the photovoltaic equipment adopts a single contact point, which reduces the processing complexity of the first pressure block 210 and the second pressure block 220 and reduces the production and installation costs of parts; the edge area is only reinforced by the third pressure block 230 with double contact points, which ensures the stability of the edge while avoiding excessive cost investment.

[0110] See Figure 6 In some embodiments, the third clamping block 230 is engaged with the purlin 3000 along a first direction. The engagement direction of the third clamping block 230 with the purlin 3000 is the first direction, which is consistent with the engagement direction of the first clamping block 210 and the second clamping block 220 with the purlin 3000. Installers do not need to frequently switch operating angles and can use the same installation action to align and push in to complete the engagement of the edge and middle area clamping blocks, reducing the learning cost and error rate of operation and improving the overall installation efficiency.

[0111] See Figure 5 In some embodiments, the third clamping block 230 is engaged with the first frame 110 on one side of the edge of the photovoltaic device, along the second direction. The third clamping block 230 is also engaged with the second frame 120 on the other side of the edge of the photovoltaic device, along the third direction. The third clamping block 230 provides lateral constraint by tightening in opposite directions on both sides of the photovoltaic device, effectively limiting the movement of the edge frame assembly and the photovoltaic support 2000 along the width direction, solving the problem of lateral displacement of the photovoltaic device edge due to the lack of adjacent support cooperation, and improving the stability of the edge structure.

[0112] See Figure 1In some embodiments, the first frame 110 is provided with a first cavity 111, and one end of the photovoltaic bracket 2000 is installed in the first cavity 111. The second frame 120 is provided with a second cavity 121, and the other end of the photovoltaic bracket 2000 is installed in the second cavity 121. The first frame 110 and the second frame 120 can respectively wrap around both ends of the photovoltaic bracket 2000 through the first cavity 111 and the second cavity 121, significantly increasing the contact area between the photovoltaic bracket 2000 and the frame assembly 100. This can evenly distribute the weight of the photovoltaic bracket 2000 and the load of the photovoltaic panel onto the frame assembly 100, improving connection stability and load-bearing capacity. At the same time, the first cavity 111 and the second cavity 121 provide a precise embedded installation reference for the end of the photovoltaic bracket 2000. During installation, the end of the photovoltaic bracket 2000 only needs to be directly embedded into the corresponding cavity to complete the initial positioning. There is no need to repeatedly calibrate the relative position of the frame and the bracket, reducing installation misalignment and rework, reducing operational difficulty, and improving assembly efficiency.

[0113] In some embodiments, the first frame 110 and the second frame 120 have the same structure. The first frame 110 and the second frame 120 are mass-produced using a single mold, eliminating the need to develop separate molds for the two types of frames and significantly reducing processing costs. During installation, there is no need to distinguish between the first frame 110 and the second frame 120, reducing the risk of parts confusion; during subsequent maintenance and replacement, the same type of frame can be directly used for replacement without matching different specifications, improving maintenance convenience and reducing operation and maintenance costs.

[0114] It is understood that in the photovoltaic installation structure 1000 of this application embodiment, when connecting the photovoltaic bracket 2000 and the purlin 3000, all key snap-fit ​​and installation actions correspond to a fixed direction: for example, the first pressing block 210, the second pressing block 220, and the third pressing block 230 are all snapped with the purlin 3000 in the vertical direction, and the first pressing block 210, the second pressing block 220, and the third pressing block 230 are all snapped with the frame assembly 100 in the horizontal opposite direction, eliminating the need for complex multi-directional composite actions. A robotic arm can be used to provide installation power; the robotic arm only needs to push vertically or horizontally to cover most of the installation steps, improving installation efficiency. Using automated components such as robotic arms significantly improves installation efficiency, shortens project cycles, and simultaneously enhances installation accuracy.

[0115] See Figure 5 At least one embodiment of this application provides a photovoltaic device, which includes a photovoltaic mounting structure 1000, a photovoltaic bracket 2000, and a purlin 3000 as described in any of the above embodiments. The photovoltaic bracket 2000 is connected to the photovoltaic mounting structure 1000 and is mounted on the purlin 3000 via the photovoltaic mounting structure 1000.

[0116] According to the photovoltaic equipment of this application embodiment, a snap-fit ​​point is provided between the first pressure block 210 and the second pressure block 220. After the photovoltaic equipment is installed, the first pressure block 210 and the second pressure block 220 between adjacent photovoltaic brackets 2000 are tightly connected through the snap-fit ​​point, integrating the originally independent individual photovoltaic brackets 2000 into a coherent overall array. This can effectively disperse the impact of negative pressure wind load on individual components, avoid deformation and detachment of local components due to concentrated force, significantly improve the wind load resistance of the entire photovoltaic equipment, and ensure structural stability under extreme weather conditions such as strong winds. The bottom of the first pressure block 210, the second pressure block 220, and the third pressure block 230 can all snap-fit ​​with the purlin 3000. During installation, they can be pre-fixed with the purlin 3000. After the component is initially placed on the purlin 3000, it can maintain a stable position without continuous manual support, completely eliminating the waiting time for manual support. This not only reduces the operational intensity of the installers and avoids safety hazards caused by component slippage, but also allows the installers to carry out subsequent snap-fit ​​operations simultaneously, significantly improving on-site installation efficiency.

[0117] See Figure 8 At least one embodiment of this application proposes a photovoltaic equipment installation method, which includes the following specific steps:

[0118] Step S100: Provide the photovoltaic installation structure 1000, photovoltaic bracket 2000, and purlin 3000 according to any of the above embodiments.

[0119] Step S200: Install the photovoltaic bracket 2000 onto the purlin 3000 via the photovoltaic installation structure 1000.

[0120] According to the photovoltaic equipment installation method of this application embodiment, the corresponding pressure blocks can be pre-installed at the designated positions of the frame components 100 of the photovoltaic bracket 2000 before installation, eliminating the need for on-site alignment and assembly. During robot operation, the robot only needs to grasp the pre-installed components and press them down in a preset direction, such as the first direction, i.e., the vertical direction, to complete the synchronous engagement of the pressure block components 200 and purlins 3000, and the first pressure block 210 and the second pressure block 220. The entire process does not require the robot to perform complex multi-directional adjustment actions, greatly reducing the operational difficulty of automated equipment and adapting to the batch installation needs of robot operators in large-scale projects.

[0121] In some embodiments, step S200, installing the photovoltaic bracket 2000 onto the purlin 3000 via the photovoltaic mounting structure 1000, specifically includes:

[0122] Step S210: Install the first frame 110 and the second frame 120 at both ends of the photovoltaic bracket 2000.

[0123] Step S220: Connect the first pressing block 210 to the first frame 110, and connect the second pressing block 220 to the second frame 120 to form the first semi-finished product.

[0124] Step S230: Engage the first pressing block 210 and the second pressing block 220 with the purlin 3000 respectively, so that the first semi-finished product is installed on the purlin 3000.

[0125] See Figure 9 , Figure 10 , Figure 11 and Figure 12 Specifically, in step S210, the frame assembly 100 is pre-installed, the second frame 120 is installed along the second direction to the left end of the photovoltaic bracket 2000, and the first frame 110 is installed along the third direction to the right end of the photovoltaic bracket 2000.

[0126] In step S220, the first semi-finished product, the second semi-finished product, and the third semi-finished product are assembled. Assembling the first semi-finished product includes pushing the second pressing block 220 along a second direction to engage with the second frame 120, and pushing the first pressing block 210 along a third direction to engage with the first frame 110, forming a first semi-finished product that can be transported as a whole. Assembling the second semi-finished product includes pushing the third pressing block 230 along a second direction to engage with the second frame 120, and pushing the first pressing block 210 along a first direction to engage with the first frame 110, forming a second semi-finished product that can be transported. Assembling the third semi-finished product includes pushing the second pressing block 220 along a second direction to engage with the second frame 120, and pushing the third pressing block 230 along a third direction to engage with the first frame 110, forming a third semi-finished product that can be transported.

[0127] Step S230 further includes: first, installing the second semi-finished product on two purlins 3000, that is, snapping the third pressure block 230 on the left end of the second semi-finished product to the first purlin 3000, and snapping the first pressure block 210 on the right end of the second semi-finished product to the second purlin 3000; then snapping the second pressure block 220 on the left end of one first semi-finished product to the second purlin 3000, and simultaneously snapping the second pressure block 220 on the left end of the first semi-finished product to the first pressure block 210 on the left end of the second semi-finished product; then taking another first semi-finished product and installing them sequentially from left to right; when installing the last part, taking a third semi-finished product, snapping the second pressure block 220 on the left end of the third semi-finished product to the corresponding purlin 3000, and simultaneously snapping the second pressure block 220 on the left end of the third semi-finished product to the first pressure block 210 on the right end of the adjacent first semi-finished product, thus forming a photovoltaic device.

[0128] By following the steps above, the installation process proceeds from left to right, with each step pressing down to engage the components. The steps are clear and sequential, significantly improving installation efficiency.

[0129] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are 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.

[0130] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
