Description

Technical Field

[0001] This utility model relates to the field of photovoltaic solar frame technology, specifically to a photovoltaic clamping block and a photovoltaic frame assembly. Background Technology

[0002] With the rapid development of the new energy industry, solar energy has been widely used and developed due to its energy-saving, environmentally friendly, and renewable characteristics, leading to the emergence of solar photovoltaic panels (also known as photovoltaic modules). Photovoltaic panels can convert solar energy into electrical energy, reducing the cost of power generation.

[0003] When using photovoltaic (PV) modules, they need to be fixed to the ground, roof, curtain wall, etc., making their fixation particularly important. To secure the PV modules and maintain a certain angle, clamps are used to fix the frame of the PV modules. However, existing clamps, which are generally C-shaped or U-shaped, have structural defects. These clamps only surround the top, sides, and back (bottom) of the frame. When subjected to external forces such as strong winds, the back of the PV module will be stressed, leaving a large portion of the frame corresponding to the back of the clamp in a suspended state. This can easily damage the frame and PV module, leading to damage to the solar panels, increased maintenance costs, and significant losses. Moreover, these clamps are usually one-piece structures, which are limited by the shape of the top surface of the PV frame. Utility Model Content

[0004] In view of this, the present invention provides a photovoltaic pressure block and a photovoltaic frame assembly, which can effectively apply pressure to the photovoltaic frame to make it firmly fixed, thereby reducing the damage rate of photovoltaic modules and reducing maintenance costs.

[0005] To solve at least one of the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A photovoltaic pressing block according to a first aspect of the present invention is used for a photovoltaic frame assembly, comprising:

[0007] The first pressing block has a top plate on its top.

[0008] The second pressure block is detachably connected to the first pressure block. The bottom of the second pressure block is provided with a base plate, which is parallel to the top plate. The base plate is provided with an upwardly protruding mounting part, which is used to connect with the mounting hole at the bottom of the photovoltaic frame of the photovoltaic frame module.

[0009] The bottom plate and the top plate form a C-shaped groove, which is used to hold the photovoltaic frame, and the mounting part is located in the C-shaped groove.

[0010] Furthermore, a first middle horizontal plate is provided on one side of the first pressing block, and a second middle horizontal plate is provided on one side of the second pressing block. The first and second middle horizontal plates are parallel to the bottom plate, and the first and second middle horizontal plates are detachably connected. The first middle horizontal plate is located above the second middle horizontal plate, and the first and second middle horizontal plates are located outside the C-shaped groove and close to the middle of the C-shaped groove.

[0011] Furthermore, the photovoltaic block also includes a first fastener, a first through hole is provided on the first middle horizontal plate, and a second through hole is provided on the second middle horizontal plate for corresponding to the first through hole. The first fastener passes through the first through hole and the second through hole and is connected to the corresponding crossbeam to install the first block and the second block on the crossbeam.

[0012] Furthermore, the photovoltaic block also includes a second fastener, and a third through hole is provided on the base plate. The third through hole is used to correspond to the fourth through hole on the extension plate at the bottom of the photovoltaic frame. The second fastener passes through the third through hole and the fourth through hole and is connected to the crossbeam.

[0013] Furthermore, the first pressing block also includes:

[0014] The first vertical plate is perpendicular to the first middle horizontal plate. The top of the first vertical plate is connected to one end of the top plate, and the bottom of the first vertical plate is connected to one end of the first middle horizontal plate.

[0015] The second vertical plate is perpendicular to the first middle horizontal plate. The top of the second vertical plate is connected to the end of the first middle horizontal plate away from the first vertical plate. The second vertical plate is parallel to the first vertical plate.

[0016] Furthermore, the first pressing block also includes:

[0017] The bottom pressure foot is located at the bottom of the second vertical plate, and the bottom surface of the bottom pressure foot is flush with the bottom surface of the base plate.

[0018] Furthermore, the second pressing block also includes:

[0019] The third vertical plate has its top connected to one end of the second middle horizontal plate and its bottom connected to one end of the bottom plate. The third vertical plate is perpendicular to the second middle horizontal plate and parallel to the first vertical plate. The bottom of the first vertical plate corresponds to the top of the third vertical plate. The bottom plate, the third vertical plate, the first vertical plate, and the top plate form a C-shaped groove.

[0020] Furthermore, the second horizontal plate is located between the second vertical plate and the third vertical plate, and the second vertical plate has a groove for engaging with the end of the second horizontal plate.

[0021] Furthermore, the mounting part is perpendicular to the base plate, and the upper end of the mounting part is provided with a limiting part that extends outward in a direction parallel to the base plate. The limiting part is used to pass through the mounting hole and extend above the mounting hole. The second pressing block moves relative to the photovoltaic frame so that the limiting part presses against the top side of the mounting hole.

[0022] A photovoltaic frame assembly according to a second aspect embodiment of the present invention includes:

[0023] Multiple photovoltaic blocks, wherein the photovoltaic blocks are photovoltaic blocks according to any of the embodiments of the first aspect described above;

[0024] A photovoltaic frame, with multiple photovoltaic blocks used to mount the photovoltaic frame onto the corresponding crossbeams.

[0025] The above-mentioned technical solution of this utility model has at least one of the following beneficial effects:

[0026] According to the photovoltaic pressing block and photovoltaic frame assembly of the present invention, the top plate of the first pressing block and the bottom plate of the second pressing block are arranged in parallel, forming an I-shaped groove for holding the photovoltaic frame. The detachable connection method is, for example, to fix the first pressing block and the second pressing block with bolts, so that the top plate of the first pressing block and the bottom plate of the second pressing block apply a pressing force between the top surface and the back surface of the photovoltaic frame, so that the bottom surface of the I-shaped groove is completely in contact with the back surface of the photovoltaic frame, providing stable support and avoiding the photovoltaic frame from being suspended in the air corresponding to the back surface of the photovoltaic pressing block, thus preventing damage to the frame assembly.

[0027] Meanwhile, the base plate of the second pressure block is also provided with an installation part. When installing the photovoltaic pressure block and the photovoltaic frame, the installation part on the base plate of the second pressure block is first connected to the installation hole at the bottom of the photovoltaic frame. The installation part can be, for example, a square protrusion, and the installation hole can be, for example, a corresponding square hole. This further limits the photovoltaic frame in the U-shaped groove, so that the photovoltaic frame is firmly fixed in all directions in the U-shaped groove, thereby reducing the shaking of the photovoltaic frame module, preventing the photovoltaic pressure block from falling off, and further reducing the damage rate of the photovoltaic module and reducing maintenance costs.

[0028] Furthermore, the existing integrated clamping blocks cannot effectively press the top and bottom plates of the U-shaped groove onto the photovoltaic frame, and are also inconvenient for later inspection and maintenance. In contrast, the first and second clamping blocks of this application adopt a separate structure, making installation and disassembly simpler and faster. Depending on different practical needs, the shape of the top surface of the photovoltaic frame sometimes needs to be changed. For example, the top surface of the photovoltaic frame may sometimes require protrusions or grooves. In such cases, the photovoltaic clamping blocks of this application adopt a separate structure, facilitating timely adjustment and replacement of the first clamping block to accommodate different types of photovoltaic frames. This ensures that the installation of the photovoltaic frame modules is not limited by changes in the top surface shape of the photovoltaic frame, improving flexibility and adaptability.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0041] Unless otherwise defined, the technical or scientific terms used in this invention shall have the ordinary meaning understood by one of ordinary skill in the art to which this invention pertains. The terms "first," "second," and similar terms used in this invention do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Similarly, the terms "a" or "one," etc., do not indicate a quantity limitation, but rather indicate the presence of at least one. The terms "connected" or "linked," etc., are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. "Up," "down," "left," "right," etc., are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship also changes accordingly.

[0042] The photovoltaic pressing block 100 according to the first aspect of the present invention will now be described in detail with reference to the accompanying drawings.

[0043] Specifically, such as Figures 1 to 6 As shown, the photovoltaic pressing block 100 according to the first aspect of the present invention is used for a photovoltaic frame assembly and may include: a first pressing block 110 and a second pressing block 120.

[0044] The first pressing block 110 has a top plate 111 at its top. The first pressing block 110 is detachably connected to the second pressing block 120. The second pressing block 120 has a bottom plate 121 at its bottom, which is parallel to the top plate 111. The bottom plate 121 has an upwardly protruding mounting part 130, which is used to connect with the mounting hole 210 at the bottom of the photovoltaic frame 200 of the photovoltaic frame module. An I-shaped groove is formed between the bottom plate 121 and the top plate 111. The I-shaped groove is used to hold the photovoltaic frame 200, and the mounting part 130 is located within the I-shaped groove.

[0045] The following is combined Figures 1 to 6 Briefly describe the working process of the photovoltaic briquette 100:

[0046] First, at the predetermined installation location (such as a roof, ground, or other platform), determine the installation positions of the photovoltaic mounting block 100 and the photovoltaic frame 200. Place the second mounting block 120 below the photovoltaic frame 200, so that the mounting part 130 on the bottom plate 121 of the second mounting block 120 is connected to the mounting hole 210 at the bottom of the photovoltaic frame 200. Then, place the first mounting block 110 above the top of the photovoltaic frame 200, so that an I-shaped groove is formed between the top plate 111 of the first mounting block 110 and the bottom plate 121 of the second mounting block 120, and the photovoltaic frame 200 is held in the I-shaped groove. The first pressure block 110 and the second pressure block 120 are detachably connected and can be fixed by, for example, bolts. The top plate 111 of the first pressure block 110 and the bottom plate 121 of the second pressure block 120 apply pressure to the top and bottom surfaces (i.e., the back surface) of the photovoltaic frame 200, respectively. At the same time, the side of the U-shaped groove is completely fitted to the side of the photovoltaic frame 200, providing additional support.

[0047] Therefore, according to the photovoltaic pressing block 100 and photovoltaic frame 200 assembly of this utility model embodiment, the top plate 111 of the first pressing block 110 and the bottom plate 121 of the second pressing block 120 of the photovoltaic pressing block 100 are arranged in parallel, forming an inverted groove for holding the photovoltaic frame 200. The detachable connection method is, for example, to use bolts to fix the first pressing block 110 and the second pressing block 120, so that the top plate 111 of the first pressing block 110 and the bottom plate 121 of the second pressing block 120 apply a pressing force between the top surface and the back surface of the photovoltaic frame 200, so that the bottom surface of the inverted groove completely fits the back surface of the photovoltaic frame 200, providing stable support and avoiding the photovoltaic frame 200 from being suspended in the back surface of the photovoltaic pressing block 100, which is less likely to cause damage to the frame assembly.

[0048] Meanwhile, the base plate 121 of the second pressure block 120 is also provided with an installation part 130. When the photovoltaic pressure block 100 and the photovoltaic frame 200 are installed, the installation part 130 on the base plate 121 of the second pressure block 120 is first connected to the installation hole 210 at the bottom of the photovoltaic frame 200. The installation part 130 can be, for example, a square protrusion, and the installation hole 210 can be, for example, a corresponding square hole. This further limits the photovoltaic frame 200 in the U-shaped groove, so that the photovoltaic frame 200 is firmly fixed in all directions in the U-shaped groove, thereby reducing the shaking of the photovoltaic frame 200 module and preventing the photovoltaic pressure block 100 from falling off, thereby further reducing the damage rate of the photovoltaic module and reducing maintenance costs.

[0049] Furthermore, the existing integrated clamping block structure cannot effectively press the top plate 111 and bottom plate 121 of the U-shaped groove onto the photovoltaic frame 200, and it is also inconvenient for later inspection and maintenance. In contrast, the first clamping block 110 and the second clamping block 120 of this application adopt a separate structure, making installation and disassembly simpler and faster. Depending on different practical needs, the top surface shape of the photovoltaic frame 200 sometimes needs to be changed. For example, the top surface of the photovoltaic frame 200 may sometimes require protrusions or grooves. In this case, the photovoltaic clamping block 100 of this application adopts a separate structure, which facilitates timely adjustment and replacement of the first clamping block 110 to meet different types of photovoltaic frames 200. This ensures that the installation of the photovoltaic frame 200 modules is not limited by changes in the top surface shape of the photovoltaic frame 200, improving flexibility and adaptability.

[0050] In some embodiments of this utility model, such as Figures 1 to 2 As shown, a first horizontal plate 112 is provided on one side of the first pressing block 110, and a second horizontal plate 122 is provided on one side of the second pressing block 120. The first and second horizontal plates 112 and 122 are parallel to the base plate 121, respectively. The first and second horizontal plates 112 and 122 are detachably connected. The first horizontal plate 112 is located above the second horizontal plate 122. The first and second horizontal plates 112 and 122 are located outside the U-shaped groove and close to the middle of the U-shaped groove, which can better disperse and resist external forces and prevent local stress concentration from causing structural damage. Thus, through the design of the first and second horizontal plates 112 and 122, the contact area of ​​the first pressing block 110 and the second pressing block 120 is increased. Under severe weather conditions such as strong winds, the external forces from the back of the photovoltaic frame 200 can be better dispersed, effectively improving the strength of the photovoltaic pressing block 100 structure.

[0051] In some embodiments of this utility model, such as Figures 1 to 2 As shown, the photovoltaic pressure block 100 also includes a first fastener (not shown), which can be a bolt or other fixing component. A first through hole 116 is provided on the first intermediate horizontal plate 112, and a second through hole 124 corresponding to the first through hole 116 is provided on the second intermediate horizontal plate 122. The first fastener passes through the first through hole 116 and the second through hole 124 and connects to the corresponding crossbeam (not shown) to install the first pressure block 110 and the second pressure block 120 onto the crossbeam. Thus, the first fastener sequentially passes through the first through hole 116 of the first intermediate horizontal plate 112 and the second through hole 124 of the second intermediate horizontal plate 122 to install the first pressure block 110 and the second pressure block 120 onto the crossbeam, which is simple to operate and provides a stable and effective solution. The design of the first fastener also facilitates later inspection and maintenance; if adjustment or replacement of corresponding components is required, only the first fastener needs to be loosened.

[0052] In some embodiments of this utility model, such as Figures 1 to 2As shown, the photovoltaic pressure block 100 also includes a second fastener (not shown), which can be, for example, a bolt or other fixing component. A third through hole 125 is also provided on the base plate 121, which corresponds to a fourth through hole 230 on the extension plate 220 at the bottom of the photovoltaic frame 200. The second fastener passes through the third through hole 125 and the fourth through hole 230 to connect with the crossbeam. Similarly, the second fastener passes through the third through hole 125 on the base plate 121 and the fourth through hole 230 on the extension plate 220 at the bottom of the photovoltaic frame 200, further firmly connecting the photovoltaic pressure block 100, the photovoltaic frame 200, and the corresponding crossbeam. This method is simple to operate, stable, and effective, further enhancing the stability of the photovoltaic frame assembly. The design of the second fastener also facilitates maintenance and replacement.

[0053] In some embodiments of this utility model, such as Figures 1 to 2 As shown, the first pressing block 110 also includes: a first vertical plate 113 and a second vertical plate 114.

[0054] The first vertical plate 113 is perpendicular to the first middle horizontal plate 112. The top of the first vertical plate 113 is connected to one end of the top plate 111, and the bottom of the first vertical plate 113 is connected to one end of the first middle horizontal plate 112. The second vertical plate 114 is perpendicular to the first middle horizontal plate 112. The top of the second vertical plate 114 is connected to the end of the first middle horizontal plate 112 away from the first vertical plate 113, and the second vertical plate 114 is parallel to the first vertical plate 113.

[0055] Specifically, such as Figures 1 to 2 As shown, the design of the first vertical plate 113 and the second vertical plate 114 enhances the structural stability of the first pressure block 110 not only laterally (through the detachable connection of the first middle horizontal plate 112 and the second middle horizontal plate 122), but also improves the structural rigidity and support force longitudinally (due to the arrangement of the first vertical plate 113 and the second vertical plate 114). When the first pressure block 110 and the second pressure block 120 are connected to the corresponding horizontal beams via the first fasteners, the second vertical plate 114 abuts against the horizontal beams, providing stable and effective support longitudinally, making the photovoltaic frame modules less prone to displacement or detachment under strong wind conditions.

[0056] In some embodiments of this utility model, such as Figure 1As shown, the first pressure block 110 also includes a bottom pressure foot 115, which is disposed at the bottom of the second vertical plate 114, and the bottom surface of the bottom pressure foot 115 is flush with the bottom surface of the base plate 121. On the one hand, the bottom pressure foot 115 increases the contact area between the photovoltaic pressure block 100 and the mounting surface (such as the crossbeam). In the event of strong winds or vibration, the bottom pressure foot 115 can provide additional support to prevent the photovoltaic frame module from shifting or swaying. On the other hand, the bottom pressure foot 115 can adapt to different types of mounting surfaces, whether smooth or slightly uneven, reducing the adjustment and correction time during installation and simplifying the installation process.

[0057] In some embodiments of this utility model, such as Figure 1 As shown, the second pressure block 120 further includes a third vertical plate 123. The top of the third vertical plate 123 is connected to one end of the second middle horizontal plate 122, and the bottom is connected to one end of the bottom plate 121. The third vertical plate 123 is perpendicular to the second middle horizontal plate 122 and parallel to the first vertical plate 113. The bottom of the first vertical plate 113 corresponds to the top of the third vertical plate 123. The bottom plate 121, the third vertical plate 123, the first vertical plate 113, and the top plate 111 form a U-shaped groove. Thus, the second pressure block 120 improves the rigidity and supporting force of the structure in the longitudinal direction. The bottom of the first vertical plate 113 corresponds to the top of the second vertical plate 114, and thus the first pressing block 110 and the second pressing block 120 provide stable and effective support in the longitudinal direction. The bottom plate 121, the third vertical plate 123, the first vertical plate 113 and the top plate 111 form a U-shaped groove to hold the photovoltaic frame 200. The external force from the back of the photovoltaic frame 200 on the photovoltaic pressing block 100 can be effectively dispersed, which improves the installation stability of the photovoltaic frame module and makes the photovoltaic frame module less likely to shift or fall off under strong wind conditions.

[0058] In some embodiments of this utility model, such as Figures 1 to 4 As shown, the second horizontal plate 122 is located between the second vertical plate 114 and the third vertical plate 123. The second vertical plate 114 has a groove 117 for cooperating with the end of the second horizontal plate 122.

[0059] In other words, the design of the groove 117 allows the end of the second horizontal plate 122 to be inserted into the groove 117 of the second vertical plate 114, thereby enhancing the connection stability between the first pressure block 110 and the second pressure block 120 and reducing the risk of loosening or detachment due to external forces. Simultaneously, in addition to the corresponding first through hole 116 on the first horizontal plate 112 and the second through hole 124 on the second horizontal plate 122 serving as mounting positioning holes, the groove 117 designed on the second vertical plate 114 further improves assembly accuracy and reduces the risk of instability due to installation errors.

[0060] In some embodiments of this utility model, such as Figures 1 to 2As shown, the mounting part 130 is perpendicular to the base plate 121. A limiting part 131 extending outwards in a direction parallel to the base plate 121 is provided at the upper end of the mounting part 130. The limiting part 131 passes through the mounting hole 210 and extends above the mounting hole 210. The second pressing block 120 moves relative to the photovoltaic frame 200 so that the limiting part 131 presses against the top side of the mounting hole 210. In other words, after the mounting part 130 passes through the mounting hole 210 at the bottom of the photovoltaic frame 200, the limiting part 131, through relative movement of the second pressing block 120, presses against the top side of the mounting hole 210, thus locking the photovoltaic frame 200 and preventing it from falling off under wind or other external forces. This further enhances the fixing effect of the photovoltaic pressing block 100 on the photovoltaic frame 200. Similarly, it also improves assembly accuracy and avoids potential problems caused by manual installation errors.

[0061] In summary, combining Figures 1 to 6 The working process of the photovoltaic pressing block 100 according to one embodiment of this utility model is described in general:

[0062] The operator first determines the installation positions of the photovoltaic mounting block 100 and the photovoltaic frame 200 at a predetermined installation location (such as a roof, ground, or other platform). Next, the operator places the second mounting block 120 below the photovoltaic frame 200, aligning the mounting portion 130 on the base plate 121 of the second mounting block 120 with the mounting hole 210 at the bottom of the photovoltaic frame 200. Then, the operator moves the second mounting block 120 relative to the photovoltaic frame 200, causing the limiting portion 131 to press against the top side of the mounting hole 210. Afterward, the operator passes the second fastener through the third through hole 125 and the fourth through hole 230, thereby connecting the second mounting block 120, the photovoltaic frame 200, and the corresponding crossbeam. Finally, the operator places the first pressure block 110 on top of the photovoltaic frame 200, with the bottom of the first vertical plate 113 and the top of the third vertical plate 123 corresponding. The bottom plate 121, the third vertical plate 123, the first vertical plate 113, and the top plate 111 form a U-shaped groove. The first fastener passes through the first through hole 116 and the second through hole 124, fixing the first pressure block 110, the second pressure block 120, and the corresponding crossbeams. The top plate 111 of the first pressure block 110 and the bottom plate 121 of the second pressure block 120 apply pressure to the top and bottom surfaces of the photovoltaic frame 200, respectively, while the sides of the U-shaped groove completely conform to the sides of the photovoltaic frame 200. Thus, the photovoltaic frame 200 is firmly fixed by the photovoltaic pressure block 100, reducing the swaying of the photovoltaic frame assembly, thereby reducing the damage rate of the photovoltaic assembly and lowering maintenance costs.

[0063] According to the photovoltaic frame assembly of the second aspect embodiment of the present invention, such as Figures 1 to 6As shown, it includes: a plurality of photovoltaic clamping blocks 100 and a photovoltaic frame 200. The photovoltaic clamping blocks 100 are the photovoltaic clamping blocks 100 of any embodiment of the first aspect described above. The plurality of photovoltaic clamping blocks 100 are used to mount the photovoltaic frame 200 on corresponding crossbeams.

[0064] Therefore, the photovoltaic frame assembly of this utility model not only improves the installation stability of the photovoltaic module, but also simplifies the installation process, enhances the reliability and safety of the system, and prevents the photovoltaic module from swaying due to the impact of strong winds. It can be applied to marine environments with higher load requirements.

[0065] Furthermore, in some other embodiments, such as Figure 6 As shown, combined with Figure 5 Due to space constraints, the extension plate 220 on the photovoltaic frame 200 is relatively short, so the fourth through hole 230 may not be provided. In this case, the third through hole 125 may also not be provided on the base plate 121 of the photovoltaic pressure block 100 in this embodiment of the present invention. That is, the second fastener does not need to pass through the third through hole 125 and the fourth through hole 230 to fix the photovoltaic frame 200, the second pressure block 120 and the corresponding crossbeam. The remaining structure and installation method of the photovoltaic pressure block 100 and the photovoltaic frame 200 remain unchanged, and a stable fixation can still be achieved. This will not be elaborated here.

[0066] Based on the above embodiments of the present invention, in the absence of explicit denial or conflict, the technical features of one embodiment can be advantageously combined with one or more other embodiments.

[0067] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
