Detailed Implementation

[0046] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0047] Referring to Figure 1, which illustrates a photovoltaic fence according to an embodiment of this application, the photovoltaic fence includes: a base beam 1, photovoltaic modules 2, columns 3, connecting plates 4, connectors 5, and crossbeams 6; one end of multiple columns 3 is parallel to and spaced apart on the base beam 1 along the length direction of the base beam 1, and the crossbeams 6 are connected to the other end of the columns 3; a connecting plate 4 is provided on the column 3, and the side frame 21 of the photovoltaic module is fixedly connected to the connecting plate 4 through the connectors 5, and a first gap is left between the side frame 21 of the photovoltaic module and the column 3; the column 3 is perpendicular to the base beam 1.

[0048] In the photovoltaic fence provided in this application embodiment, firstly, the columns 3 are fixedly installed on the foundation beam 1 at a set interval. The columns 3 are perpendicular to the foundation beam 1 and parallel to each other. Then, photovoltaic modules 2 are installed between the columns 3, with the photovoltaic modules 2 as the wall surface. After the fixed connection between the photovoltaic modules 2 and the columns 3 is completed, a crossbeam 6 is connected to the end of the column 3 away from the foundation beam 1 to form a photovoltaic fence. A connecting plate 4 is installed on the column 3. The photovoltaic module 2 is fixedly connected to the connecting plate 4 through the side frame and connector 5, so that the photovoltaic module 2 is installed between the columns 3 to form the wall surface of the photovoltaic fence. Since the connecting plate 4 extends to both sides of the column 3, and the side frame 21 of the photovoltaic module is parallel to the column 3, the side frame 21 of the photovoltaic module is fixed on the connecting plate 4, so that the side frame 21 of the photovoltaic module and the column 3 are separated by a first gap. When the flowing air impacts the photovoltaic fence, some air will pass directly through the first gap, thereby reducing the contact area between the photovoltaic fence and the flowing air, further reducing the air flow impacting the photovoltaic fence per unit time, and effectively reducing the wind load acting on the photovoltaic fence per unit time. This ensures the structural stability of the photovoltaic fence under the action of wind and reduces the safety hazards such as component damage and disintegration that may occur in the photovoltaic fence during windy weather.

[0049] At least one connecting plate 4 can be set on each of the opposite sides of the column 3 in the direction parallel to the foundation beam 1, so that one column 3 can be fixedly connected to two photovoltaic modules 2 at the same time, and both photovoltaic modules 2 are parallel to the length direction of the foundation beam 1. Taking the photovoltaic fence shown in Figure 1 as an example, two connecting plates 4 can be set on each side of the column 3, and the connecting plates 4 on both sides of the column 3 are symmetrical to each other.

[0050] In some embodiments not shown, such as the position of the intersection of multiple foundation beams 1 in different directions, the connecting plate 4 can be adaptively adjusted according to the length direction of the foundation beam 1, and is not limited to the opposite sides of the column 3. For example, the column 3 at the intersection is provided with two connecting plates 4, and the two connecting plates 4 are set at an angle, such as vertically.

[0051] For example, the connecting plate 4 can be installed on the column 3 by welding or by fasteners such as screws.

[0052] The connection points of multiple columns 3 and crossbeams 6 can be set flush, so that the crossbeams 6 are parallel to the foundation beams 1. This makes the frame structure of the photovoltaic wall composed of the foundation beams 1, columns 3, and crossbeams 6 more regular and beautiful, and facilitates the installation of photovoltaic modules 2 of uniform specifications.

[0053] Referring to Figure 2, which shows another photovoltaic fence in this embodiment of the application, the connection position between the beam 6 and the column 3 can be set at the end of the other end of the column 3 as shown in Figure 1, or at other parts of the other end of the column 3 (e.g., the middle of the column 3) as shown in Figure 2.

[0054] In summary, in this embodiment, by setting connecting plates 4 extending from both sides of the column 3 on the column 3, the photovoltaic module 2 is connected to the column 3. The photovoltaic fence constructed in this way ensures the basic enclosure and photovoltaic power generation functions of the photovoltaic fence. At the same time, because the column 3 is connected by the extended connecting plates 4, a first ventilation gap is left between the frame of the photovoltaic module 2 and the column 3, reducing the area of ​​airflow acting on the photovoltaic fence, which is equivalent to reducing the wind load acting on the photovoltaic fence. This reduces the impact of wind load on the structural stability of the photovoltaic fence, ensures the structural stability of the photovoltaic fence, and reduces safety hazards.

[0055] Optionally, referring to Figures 3 and 4, Figure 3 shows a front view of one type of photovoltaic fence according to an embodiment of this application, which is a front view of the photovoltaic fence shown in Figure 1; Figure 4 shows a front view of another type of photovoltaic fence according to an embodiment of this application, which is a front view of the photovoltaic fence shown in Figure 2. The side length of the photovoltaic module 2 parallel to the length direction of the column 3 is less than the length of the column 3, and a second gap is left between the photovoltaic module 2 and the foundation beam 1.

[0056] Photovoltaic modules 2 with side lengths shorter than the columns 3 can be installed between the columns 3, leaving gaps along the length of the columns 3 in the photovoltaic fence, including a second gap between the foundation beam 1 and the bottom surface of the photovoltaic modules 2. This second gap provides additional space for the photovoltaic fence, and based on the same principle as the first gap, it can further reduce wind loads acting on the photovoltaic fence, enhancing its structural stability.

[0057] In addition, the second gap can prevent the photovoltaic module 2 from directly contacting the foundation beam 1, thereby avoiding the accumulation of dust that is difficult to clean due to the contact gap between the photovoltaic module 2 and the foundation beam 1. In some cases where the water depth exceeds the height of the foundation beam 1, the second gap can also prevent the photovoltaic module 2 from being soaked in the water, thereby preventing damage to the electronic components in the photovoltaic module 2.

[0058] Optionally, referring to Figure 5, which shows a connection diagram of a connector 5 in an embodiment of this application, the connector 5 includes a connecting part 52 and a snap-fit ​​part 51. The connecting part 52 is fixedly connected to the side frame 21 of the photovoltaic module; the snap-fit ​​part 51 is used to snap-fit ​​the connecting plate 4; a gasket 53 is provided at the contact position between the connector 5 and the connecting plate 4.

[0059] As shown in FIG5, one embodiment of the connector 5 may include a snap-fit ​​part 51 that is suspended and snapped onto the side of the connecting plate 4 away from the foundation beam 1, and a connecting part 52 that abuts against the connecting plate 4 and is fixedly connected to the side frame 21 of the photovoltaic module.

[0060] The snap-fit ​​part 51 and the connecting part 52 can be components divided according to their functions. During manufacturing, the connector 5 can be integrally processed. For example, its material can be aluminum, steel, or other commonly used metals or alloys for connection. The connecting plate 4 is generally made of metal or alloy material. Therefore, a gasket 53 can be embedded between the connecting plate 4 and the connector 5 to prevent bimetallic corrosion caused by direct contact between the connecting plate 4 and the connector 5. At the same time, the gasket 53 can be made of rubber to enhance the friction between the connecting plate 4 and the connector 5 and prevent the connector 5 from shifting along the edge of the connecting plate 4 away from the foundation beam 1, thereby affecting the relative position of the photovoltaic module 2 and the column 3.

[0061] Optionally, referring to Figures 5, 6a-6d, 6a, 6b, 6c, and 6d respectively, we can see a front view, a side view, a top view, and an isometric view of a connector 5 and a connecting plate 4 connected in an embodiment of this application; the snap-fit ​​part 51 includes a first snap-fit ​​structure 511, the size of the first snap-fit ​​structure 511 is matched with the size of the connecting plate 4, and the first snap-fit ​​structure 511 is snapped onto one side of the connecting plate 4.

[0062] The snap-fit ​​part 51 can be a first snap-fit ​​structure 511 formed by bending the plate workpiece. The size of the first snap-fit ​​structure 511 matches the size of the connecting plate 4, so that the first snap-fit ​​structure 511 can be suspended and snapped on the side of the connecting plate 4 away from the foundation beam 1. Referring to Figure 5, the free end of the first snap-fit ​​structure (i.e., the end of the first snap-fit ​​structure 511 away from the connecting part 52) ​​can be bent outward to facilitate the connecting plate 4 entering the snap-fit ​​slot of the snap-fit ​​structure.

[0063] Optionally, referring to Figures 5 and 6a-6d, the connecting part 52 includes a first structural plate 521, a second structural plate 522, a third structural plate 523, and a fourth structural plate 524 connected in sequence; the first structural plate 521, the second structural plate 522, and the third structural plate 523 form an arched structure, the first structural plate 521 forms one inclined surface of the arched structure and connects to the snap-fit ​​part 51, the second structural plate 522 forms the top surface of the arched structure, and a third mounting hole 5221 is opened on the top surface of the arched structure. The first fastener 55 passes through the third mounting hole 5221 to fix the second structural plate 522 to the side frame 21 of the photovoltaic module, the third structural plate 523 forms the other inclined surface of the arched structure, and the fourth structural plate 524 is used to abut against the other side of the connecting plate 4 away from the snap-fit ​​part 51.

[0064] The connecting part 52 may sequentially include a first structural plate 521, a second structural plate 522, a third structural plate 523, and a fourth structural plate 524 formed by bending the same sheet metal workpiece; wherein the first structural plate 521, the second structural plate 522, and the third structural plate 523 form an arched structure, the first structural plate 521 forms one inclined surface of the arched structure and connects to the snap-fit ​​part 51, the second structural plate 522 forms the top surface of the arched structure, and the top surface of the arched structure can be parallel to the surface of the connecting plate 4 when the connecting part 52 abuts against the connecting plate 4. Referring to Figures 6b and 6c, the side frame 21 of the photovoltaic module contacts and connects to the second structural plate 522, and the arched structure can provide a space for accommodating the first fastener 55 connecting the side frame 21 of the photovoltaic module and the connector 5; the third structural plate 523 forms another inclined surface of the arched structure, and the fourth structural plate 524 is used to abut against the other side of the connecting plate 4 away from the snap-fit ​​part 51.

[0065] With the above-mentioned configuration, the connector 5 is suspended and snapped onto the side of the connecting plate 4 away from the foundation beam 1 via the first slot structure 511, and the connecting part 52 abuts against the surface of the connecting plate 4, so that the connector 5 can form a stable fixed connection with the connecting plate 4. At the same time, the suspension and snapping method greatly simplifies the installation process of the photovoltaic module 2, reduces the use of fasteners, and reduces the positioning requirements between the photovoltaic module 2 and the column 3 without affecting the installation accuracy, thereby reducing the installation cost and improving the installation efficiency.

[0066] Another embodiment of the connector 5 is shown in FIG7. The connector 5 may include a snap-fit ​​part 51 that is suspended and snapped onto the side of the connecting plate 4 away from the foundation beam 1, and a connecting part 52 that is fixedly connected to the side frame 21 of the photovoltaic module.

[0067] Optionally, referring to Figures 7, 8a-8d, and 9, Figures 8a, 8b, 8c, and 8d respectively show a front view, a side view, a top view, and an isometric view of another connector 5 connected to the connecting plate 4 in this embodiment of the present application. Figure 9 shows an isometric view of another connector 5 connected to the side frame 21 of the photovoltaic module in this embodiment of the present application. The connecting part 52 may include a fifth structural plate 525 and a second slot structure 526. The second slot structure 526 is connected to the snap-fit ​​part 51 through the fifth structural plate 525. The slot of the second slot structure 526 faces the side frame 21 of the photovoltaic module. The size of the second slot structure 526 matches the size of the sixth structural plate 211 of the side frame 21 of the photovoltaic module. The sixth structural plate 211 of the side frame 21 of the photovoltaic module is snapped into the second slot structure 526 and fixedly connected to the connecting part 52 through the first fastener 55.

[0068] Compared to the connector 5 shown in Figures 5 and 6a-6b, Figures 7 and 8a-8d provide another embodiment of the connector 5: the connecting part 52 may include a fifth structural plate 525 and a second slot structure 526 formed by bending and processing a sheet metal workpiece; the main body of the connecting part 52 of the connector 5 is set as the second slot structure 526, so that the sixth structural plate 211 of the side frame 21 of the photovoltaic module can be inserted into and locked in the slot of the second slot structure 526, and then the side frame 21 of the photovoltaic module and the connecting part 52 are fixedly connected by the first fastener 55.

[0069] When the sixth structural plate 211 and the connecting part 52 are fixedly connected using the first fastener 55, since the sixth structural plate 211 is inserted into the slot of the second slot structure 526, the two sides of the sixth structural plate 211 and the second slot structure 526 are simultaneously in contact. At the same time, the direct force applied by the first fastener is to the second slot structure 526, thus dispersing the load applied to the sixth structural plate 211 by the first fastener 55 and preventing the sixth structural plate 211 from being pulled and damaged by the first fastener 55 due to concentrated force.

[0070] Optionally, referring to Figures 5 and 6a-6d, or referring to Figures 7 and 8a-8d, at least one stiffener 41 is provided on one side of the connecting plate 4 perpendicular to the height direction of the column 3; the length L1 of the stiffener 41 is less than the length L2 of the connecting plate 4, the stiffener 41 is used to increase the structural strength of the connecting plate 4, and at the same time restrict the movement of the snap-fit ​​part 51 on the connecting plate 4 along the first direction X, one end of the stiffener 41 in the length direction is flush with one end of the connecting plate 4, and the distance r between the other end of the stiffener 41 in the length direction and the snap-fit ​​part 51 is 2-10mm; the first direction X is a direction parallel to the length of the connecting plate 4.

[0071] A stiffener 41 can be provided on the back of the connecting plate 4. The back of the connecting plate 4 can refer to the side away from the connecting part 52 of the connector 5. At least one stiffener 41 can be provided, and its length direction is perpendicular to the length direction of the column 3, that is, consistent with the extension direction of the connecting plate 4. By providing the stiffener 41, the connecting plate 4 can be supported, the structural strength of the connecting plate 4 can be enhanced, and the connecting plate 4 can be prevented from being damaged by wind loads perpendicular to the surface of the connecting plate 4. Referring to Figures 5 and 6a-6d, when multiple stiffeners 41 are provided, they can be arranged in parallel and spaced apart. In the connecting plate 4 shown in Figures 7 and 8a-8d, the number of stiffeners 41 is set to one, which reduces material waste while ensuring the structural strength of the connecting plate 4.

[0072] Furthermore, as shown in Figure 6a or Figure 8a, the end face of one end of the stiffening plate 41 along its length can be flush with the end face of one end of the connecting plate 4 and connected together to the column (not shown in Figure 4a or Figure 8a). The length L1 of the stiffening plate 41 is less than the length L2 of the connecting plate 4. Since the connector 5 is suspended and snapped onto the other end of the connecting plate 4, the stiffening plate 41 restricts the connector 5 from moving parallel to the length direction X of the stiffening plate 41 on the connecting plate 4, thereby preventing the connector 5 on the other side frame of the photovoltaic module 2 from falling off the corresponding connecting plate 4 and ensuring the stability of the connection between the photovoltaic module 2 and the column 3. The distance r between the other end of the stiffening plate 41 and the snap-fit ​​part 51 can be 2-10mm, thereby providing a certain adjustment distance for the snap-fit ​​part 51 of the connector 5. While ensuring that the connector 5 on the other end of the photovoltaic module 2 does not fall off the connecting plate 4, the error of the photovoltaic module 2 in the direction parallel to the extension of the connecting plate 4 is adjusted.

[0073] Optionally, referring to Figures 5, 6b, and 6d, or referring to Figures 7, 8b, and 8d, an adjusting member 54 is provided on the top outer side of the snap-fit ​​part 51. One end of the adjusting member 54 abuts against the connecting plate 4. The adjusting distance of the adjusting member 54 is 5-15mm. The adjusting member 54 is used to adjust the relative distance between the connecting member 5 and the connecting plate 4 when the connecting member 5 is snapped into the connecting plate 4.

[0074] An adjusting member 54 can be provided at the top of the snap-fit ​​part 51. One end of the adjusting member 54 passes through the top of the snap-fit ​​part 51 and abuts against the connecting plate 4. When the snap-fit ​​part 51 is suspended and snapped onto the connecting plate 4, the relative distance between the connecting member 5 and the connecting plate 4 can be adjusted by the adjusting member 54. The adjusting member 54 can be an adjusting screw. A tapping screw hole is provided at the top of the snap-fit ​​part 51. The adjusting screw passes through the tapping screw hole and abuts against the connecting plate 4. By rotating the adjusting screw, the distance in which the adjusting screw extends into the inside of the snap-fit ​​part 51 can be changed, further changing the distance between the snap-fit ​​part 51 and the side of the connecting plate 4 facing the adjusting screw. Since the first slot structure 511 is snapped onto the connecting plate 4, it can be understood that the adjustment direction of the adjusting member 54 is parallel to the slot opening orientation of the first slot structure 511. When the connecting member 5 is suspended and snapped onto the connecting plate 4, the adjustment direction of the adjusting member 54 is the second direction Y, that is, the direction parallel to the width W of the connecting plate 4.

[0075] Referring to Figure 6b or Figure 8b, the distance h1 from which the adjusting screw extends into the inner side of the locking part 51 is the adjusting distance of the adjusting screw. It can be understood that when a shim 53 is provided between the locking part 51 and the connecting plate 4, h1 is the distance between the surface of the shim 53 and the bottom of the locking groove of the locking part 51. The distance between the rib 41 near the adjusting member 54 and the side of the connecting plate 4 facing the adjusting member 54 is h2, and the depth of the locking groove of the locking part 51 is h3. Therefore, h3>(h1+h2), where the range of h1 can be controlled within 5-15mm. Through the above settings, the connecting member 5 is prevented from falling off the connecting plate 4 when adjusting the relative distance between the connecting member 5 and the connecting plate 4. It should be noted that since the snap-fit ​​part 51 is suspended and snapped onto the connecting plate 4, the anti-theft security of the photovoltaic module 2 needs to be considered. Therefore, as shown in Figure 1, when the crossbeam 6 is installed on the end face of the column 3, the width D of the third gap between the crossbeam 6 and the photovoltaic module 2 can be set as follows with h1, h2, and h3: D < (h3 - h2 - h1). This ensures that the snap-fit ​​part 51 cannot detach from the connecting plate 4 along the length direction of the column 3, thus preventing the photovoltaic module 2 from being directly removed from the connecting plate 4.

[0076] Optionally, referring to FIG10, another photovoltaic fence provided in an embodiment of this application is shown; the connector 5 includes a second fastener 56; the side frame 21 of the photovoltaic module is provided with a first mounting hole (not shown in FIG10) matching the number of connecting plates 4, and the connecting plate 4 is provided with a second mounting hole 42, the first mounting hole and the second mounting hole 42 corresponding one to one; the side frame 21 of the photovoltaic module and the connecting plate 4 are fixedly connected by the second fastener 56 passing through the first mounting hole and the second mounting hole 42 simultaneously.

[0077] Another implementation of the connector 5 is to directly use the second fastener 56 to fix the connecting plate 4 and the side frame 21 of the photovoltaic module. That is, the side frame 21 of the photovoltaic module is provided with a first mounting hole matching the number of connecting plates 4, and the connecting plate 4 is provided with a second mounting hole. The first mounting hole and the second mounting hole 42 correspond one-to-one. The second fastener 56 passes through both the first mounting hole and the second mounting hole 42 to complete the fixed connection between the photovoltaic module 2 and the column 3. For example, the second fastener 56 can be a bolt or nut. Compared with the connector solution composed of the snap-fit ​​part 51 and the connecting part 52, the connection relationship of this solution is simpler and the production and procurement cost of the parts is lower. However, this solution has higher requirements for the precision positioning of the first mounting hole and the second mounting hole, and the photovoltaic module 2 needs to be supported when fixing the photovoltaic module 2 and the column 3, which is not convenient for installation.

[0078] It should be noted that for the connector scheme consisting of the snap-fit ​​part 51 and the connecting part 52, a second mounting hole 42 corresponding one-to-one with the first mounting hole (not shown in Figure 5) can also be opened on the connecting plate 4. That is, both schemes can be provided with the first mounting hole and the second mounting hole, and compatibility between the two schemes of photovoltaic module 2 and column 3 can be achieved by only changing the connector 5. At this time, as shown in Figure 5, when the photovoltaic module 2 is installed on the connecting plate 4, the gasket 53 can cover the second mounting hole 42, thereby closing the arched structure formed by the connecting part 52. Since the arched structure accommodates the first fastener 55, the gasket 53 can prevent tools such as screwdrivers from passing through the second mounting hole 42 to remove the first fastener 55, thereby further removing the photovoltaic module 2 and causing theft.

[0079] Optionally, referring to Figure 10, the photovoltaic fence also includes a support plate 8, which is set at one end of the column 3 near the foundation beam 1. The support plate 8 is used to support the photovoltaic module 2, which facilitates the installation of the photovoltaic module 2.

[0080] An improvement can be made to the solution using the second fastener 56. A support plate 8 can be set at one end of the column 3 near the foundation beam 1. The support plate 8 can be a structure similar to a folded edge, which can support the photovoltaic module 2. When installing or replacing the photovoltaic module 2, the photovoltaic module 2 can be placed on the support plate 8 and the position of the photovoltaic module 2 can be aligned so that the first mounting hole and the second mounting hole 42 are aligned. The second fastener 56 can then be installed to fix the photovoltaic module 2 and the column 3.

[0081] Optionally, referring to Figures 7, 8a-8d and 9; the seventh structural plate 5111 of the first slot structure 511 is fitted with a limiting sleeve 5113; when the first slot structure 511 is engaged with the connecting plate 4, the limiting sleeve 5113 is fixed to the seventh structural plate 5111 by a third fastener 5114 to restrict the movement of the engaging part 51 on the connecting plate 4 along the second direction Y; the seventh structural plate 5111 is connected to the connecting part 52; the second direction Y is a direction parallel to the width W of the connecting plate 4.

[0082] The first slot structure 511 includes two parallel structural plates. A limiting sleeve 5113 can be provided on the longer structural plate of the first slot structure 511. In the embodiments of the connector 5 shown in Figures 7, 8a-8d and 9, the longer structural plate is the seventh structural plate 5111 connected to the connecting part 52. After the photovoltaic module 2 is suspended and snapped onto the connecting plate 4 through the first slot structure 511, the limiting sleeve 5113 is then installed onto the first slot structure 511 through the third fastener 5114. This can restrict the connecting plate 4 within the slot of the first slot structure 511, thereby limiting... The snap-fit ​​part 51 moves along the second direction Y on the connecting plate 4. In the photovoltaic fence shown in Figures 2 and 4, since the crossbeam 6 is not set on the end face of the column 3, the crossbeam 6 cannot play the role of anti-theft. However, the setting of the limiting sleeve 5113 can prevent the snap-fit ​​part 51 and the connecting plate 4 from moving relative to each other in the direction parallel to the second direction Y. This ensures that the snap-fit ​​part 51 cannot detach from the connecting plate 4 along the length direction of the column 3, and prevents the photovoltaic module 2 from being directly removed from the connecting plate 4, thus playing the role of anti-theft. It can be understood that when the connector 5 is attached to the connecting plate 4, the second direction Y is parallel to the width W of the connecting plate 4.

[0083] Optionally, referring to Figures 9, 11, and 12, where Figure 11 is a stacked schematic diagram of the photovoltaic modules 2 of the photovoltaic wall in this application, and Figure 12 is an enlarged schematic diagram of the Z region in Figure 11; the edge of the eighth structural plate 5112 of the first slot structure 511 is provided with a folded edge 51121; the folded edge 51121 is used to form a limiting structure with the folded edge 51121 installed on the connector 5 on the opposite side of the photovoltaic module 2, so that when multiple photovoltaic modules 2 are stacked, the limiting structure is respectively engaged with the side frame 21 of the adjacent photovoltaic modules; the eighth structural plate 5112 is away from the connecting part 52.

[0084] Referring to Figure 11, multiple photovoltaic modules 2 can be stacked together to form a pallet for storage or transportation. The side frame 21 of the photovoltaic modules can be pre-fixed to the connector 5, so that the photovoltaic modules 2 can be directly suspended on the connecting plate 4 when installing the photovoltaic fence. Meanwhile, referring to Figures 9 and 12, a folded edge 51121 can be provided on the eighth structural plate 5112 away from the connecting part 52 of the first slot structure 511. When multiple photovoltaic modules 2 are stacked together, the connectors 5 on both sides of the same photovoltaic module 2 can form a limiting structure. Referring further to Figure 12, the limiting structure can make the folded edge 51121 snap onto the side frame 21 of the next photovoltaic module, restricting the movement of the photovoltaic module 2 and preventing sliding between adjacent photovoltaic modules 2, thereby ensuring the stability of the photovoltaic module 2 stack.

[0085] Optionally, referring to Figure 3 or Figure 4, each column 3 includes an even number of connecting plates 4, and the connecting plates 4 on both sides of the column 3 are symmetrically arranged; two symmetrical connecting plates 4 on a column 3 are used to connect two adjacent photovoltaic modules 2 respectively.

[0086] Connecting plates 4 can be symmetrically installed on the column 3. On the one hand, the symmetrically installed connecting plates 4 facilitate the standardized installation of photovoltaic modules 2 and reduce installation costs. On the other hand, the symmetrically installed connecting plates 4 can enhance the aesthetics of the photovoltaic wall.

[0087] For example, referring to Figure 3 or Figure 4, four connecting plates 4 can be set on a column 3, two on each side, with the connecting plates 4 on both sides being symmetrical to each other.

[0088] Optionally, referring to Figures 13a-13c, Figures 13a, 13b, and 13c respectively show a front view, a side view, and a top view of the arrangement of photovoltaic cables 22 in a photovoltaic wall according to an embodiment of the application. Figures 13a-13c show an optional implementation of the crossbeam 6, which corresponds to the photovoltaic wall shown in Figure 1. The crossbeam 6 is a hollow crossbeam 6 with openings at both ends, and the hollow cavity of the hollow crossbeam 6 is used to accommodate the photovoltaic cables 22. Further referring to Figure 14, which is a partially enlarged schematic diagram of Figure 13b, a through hole 611 is opened on the side of the crossbeam 6 facing the foundation beam 1. The through hole 611 is located on the periphery of the connection position between the crossbeam 6 and the column 3. One end of the photovoltaic cable 22 passes through the through hole 611 and is connected to the photovoltaic module 2, and the other end of the photovoltaic cable 22 is interconnected inside the hollow cavity. The crossbeam 6 is located on the end face of the column 3 or in the middle of the column 3.

[0089] The crossbeam 6 can be set at the end of the column 3 away from the foundation beam 1 (not limited to the end face) to improve the structural stability of the photovoltaic wall. The crossbeam 6 is set as a hollow structure, so that the photovoltaic cables required for the photovoltaic module 2 can be connected and laid in the hollow cavity of the crossbeam 6. A through hole 611 is opened at the position of the crossbeam 6 near the column 3 to lead out the photovoltaic cable 22, so that the photovoltaic cable 22 can be connected to the main body of the photovoltaic module 2. At the same time, the through hole 611 can also serve as a drainage hole to facilitate the discharge of water and hot air accumulated in the hollow cavity.

[0090] For example, the crossbeam 6 may include a second bent plate 62 and a first bent plate 61. Both the first bent plate 61 and the second bent plate 62 are U-shaped components with openings formed by folding in the same direction on both sides. The first bent plate 61 is connected to the column 3 and is the main mechanical component of the crossbeam 6, and carries the photovoltaic cable 22. The opening of the first bent plate 61 is away from the foundation beam 1 (it can be understood that in the photovoltaic fence schemes shown in Figures 1, 2 and 10, the first bent plate 61 and the second bent plate 62 can be used to form the crossbeam 6). The opening of the second bent plate 62 faces the opening of the first bent plate 61. A through hole 611 is set at the bottom of the first bent plate 61. The outer diameter of the opening of the first bent plate 61 is smaller than the inner diameter of the opening of the second bent plate 62, so that the second bent plate 62 can be pressed and covered at the opening of the first bent plate 61, thereby forming a hollow cavity between the second bent plate 62 and the first bent plate 61.

[0091] By connecting the crossbeam 6 to the end face of the column 3 away from the foundation beam 1, the crossbeam 6 can avoid shading the photovoltaic module 2. When the photovoltaic wall includes the photovoltaic module 2 that generates electricity on both sides, the crossbeam 6 is set up in the manner shown in Figure 6 so that the crossbeam 6, which is a frame structure, also serves as a cable tray for the photovoltaic cable 22, which can reduce the impact of external shading on the photovoltaic module 2.

[0092] Referring to Figures 15a-15c, Figures 15a, 15b, and 15c respectively show a front view, a top view, and a partial side view of the photovoltaic cable 22 arrangement of another photovoltaic fence in the application embodiment. Figures 15a-15c show another optional implementation of the crossbeam 6, which corresponds to the photovoltaic fence shown in Figure 2 or Figure 10, wherein Figure 15c is a side view of the crossbeam 6 portion.

[0093] When the photovoltaic fence includes single-sided photovoltaic modules 2 (if it is a double-sided photovoltaic module, the beam 6 setting method shown in Figure 2 or Figure 10 will block the photovoltaic module 2 and reduce the power generation efficiency of the photovoltaic module 2), then either the method shown in Figure 13a, where the beam 6 is set on the end face of the column 3 away from the foundation beam 1, or the method shown in Figure 15a, where the beam 6 is set in the middle of the column 3 (the beam 6 can be set on the side of the photovoltaic module 2 that does not generate electricity), is used. This eliminates the need to align the end faces of multiple columns 3 away from the foundation beam 1, reduces the height adjustment requirements of the columns 3, and lowers the installation cost.

[0094] The other structures in Figures 15a-15c are the same as those in Figures 13a-13c, and will not be described again here.

[0095] Optionally, referring to Figure 1, the photovoltaic fence also includes column sleeves 7. Multiple column sleeves 7 are fixedly connected to the foundation beam 1 at intervals along the length direction of the foundation beam 1. One end of the column 3 is inserted into and fixedly connected to the inside of the column sleeve 7, so that one end of the column 3 is indirectly fixedly connected to the foundation beam 1 through the column sleeve 7.

[0096] The column 3 can be indirectly fixed on the foundation beam 1 through the column sleeve 7. By setting the depth of one end of the column 3 inserted into the column sleeve 7, the height accuracy of the other end of the column 3 can be adjusted to ensure that the end faces of multiple columns 3 away from the foundation beam 1 are flush, which facilitates the installation of the crossbeam 6.

[0097] Furthermore, referring to Figure 10, when the height accuracy requirement of the column 3 is not high, the base plate 9 can be directly installed at the bottom of the column 3 and fixedly connected to the foundation beam 1 through the base plate 9. In addition, for the scheme shown in Figure 10, using the base plate 9 instead of the column sleeve 7 can avoid the interference of the column sleeve 7 on the support plate 8.

[0098] Optionally, referring to Figure 3 or Figure 4, the height A of the foundation beam 1 is greater than or equal to 250mm, the width C of the first gap is 50-110mm, and the width B of the second gap is 50-250mm.

[0099] The height A of the foundation beam 1 can be greater than or equal to 250mm to provide a certain flood control and water-blocking capacity. To ensure ventilation in the second gap and facilitate the cleaning of related components in the event of dust or snow accumulation, and to prevent dust and snow accumulation from affecting the power generation efficiency of the photovoltaic module 2, the width B of the second gap can be set between 50-250mm. Referring to the regulations on railings and guardrails in relevant building codes, the width C of the first gap can be less than or equal to 110mm. At the same time, considering the visual aesthetics of the photovoltaic wall and its integration with the surrounding environment, as well as ensuring the flow of air through the first gap, the width C of the first gap can be greater than or equal to 50mm. That is, the width C of the first gap can be set between 50-110mm.

[0100] Optionally, referring to Figure 6b or Figure 8b, the photovoltaic fence includes a first distance h1, a second distance h2, and a third distance h3, and satisfies h3>(h1+h2); wherein, the first distance h1 is the adjustment distance of the adjusting member 54, the second distance h2 is the distance between the stiffening plate 41 near the adjusting member 54 and the side of the connecting plate 4 facing the adjusting member 54, and the third distance h3 is the depth of the snap-fit ​​groove formed by the snap-fit ​​part 51.

[0101] The relationship settings for h3, h1, and h2 can be found in the section on adjustment component 54 above, and will not be repeated here.

[0102] Optionally, referring to Figures 1, 3 and 6b, the end face of the crossbeam 6 is connected to the column 3, and a third gap is left between the photovoltaic module 2 and the crossbeam 6. The width of the third gap is D, which satisfies D<(h3-h2-h1), 15mm≤D≤25mm.

[0103] When the photovoltaic fence scheme shown in Figure 1 is adopted, the crossbeam 6 is set on the end face of the column 3 away from the foundation beam 1, so that the crossbeam 6 and the column 3 form a third gap; since the snap-fit ​​part 51 is suspended and snap-fitted on the connecting plate 4, the anti-theft security of the photovoltaic module 2 needs to be considered. For this reason, the width D of the third gap can be set as follows with h1, h2, h3 as described above: D < (h3-h2-h1), so as to ensure that the snap-fit ​​part 51 cannot detach from the connecting plate 4 along the length direction of the column 3 (which can be understood as being parallel to the second direction Y), and to prevent the photovoltaic module 2 from being directly removed from the connecting plate 4; in some embodiments, the range of the third gap D can be set to 15-25mm.

[0104] The third gap can provide additional space for the photovoltaic wall. Based on the same principle as the first gap, the third gap can further reduce the wind load acting on the photovoltaic wall and enhance the structural stability of the photovoltaic wall. The third gap can prevent the photovoltaic module 2 from directly contacting the crossbeam 6, and prevent the photovoltaic module 2 from being damaged by the crossbeam 6 in the event of large deformation of the crossbeam 6.

[0105] In summary, in this embodiment, by setting connecting plates 4 extending from both sides of the column 3 on the column 3, the photovoltaic module 2 is connected to the column 3. The photovoltaic fence constructed in this way ensures the basic enclosure and photovoltaic power generation functions of the photovoltaic fence. At the same time, the reserved first gap can reduce the area of ​​airflow acting on the photovoltaic fence, which is equivalent to reducing the wind load acting on the photovoltaic fence, thereby reducing the impact of wind load on the structural stability of the photovoltaic fence, ensuring the structural stability of the photovoltaic fence, and reducing safety hazards. In addition, the connector 5 scheme based on the connecting plate 4 can save the installation cost of the photovoltaic module 2 and improve the anti-theft capability. The crossbeam 6, which is part of the frame structure, is set at the top of the photovoltaic fence and also serves as a bridge for photovoltaic cables 22. This reduces the shading of the photovoltaic module 2 by the frame structure and photovoltaic cables 22, improves the power generation stability of the photovoltaic module 2, avoids the exposure of photovoltaic cables 22, increases the service life of photovoltaic module 2 and photovoltaic cables 22, and ensures the electrical safety of photovoltaic module 2 operation.
