[0050] Figure 1 This is a partial schematic diagram of a photovoltaic panel 100 provided according to one embodiment of the present application. Figure 2 for Figure 1 The photovoltaic barrier 100 in the figure hides the schematic diagram of the upper beam assembly 21. Figure 3 for Figure 1 A partial schematic diagram of the column assembly 11 in the photovoltaic barrier 100.

[0051] See also Figures 1 to 3 The present application provides a photovoltaic barrier 100 , which includes at least one photovoltaic unit 10 and a beam assembly 20 .

[0052] The photovoltaic unit 10 includes a column assembly 11 and a photovoltaic assembly 12 . The photovoltaic assembly 12 is provided with a junction box. The column assembly 11 is disposed at the location of the junction box and is formed with a mounting groove C1 extending vertically.

[0053] The beam assembly 20 includes an upper beam assembly 21 and a lower beam assembly 22. The upper beam assembly 21 and the lower beam assembly 22 are respectively arranged at the top and bottom ends of the photovoltaic assembly 12 and are respectively connected to the top and bottom ends of the column assembly 11 to cooperate with the photovoltaic assembly 12 to cover the installation groove C1 for accommodating the junction box.

[0054] It should be noted that the photovoltaic assembly 12 includes a photovoltaic panel and a junction box (not shown). The junction box is mounted on the photovoltaic panel and is capable of converting light energy into electrical energy and outputting it through the junction box. The photovoltaic assembly can be a double-glass photovoltaic assembly, a single-glass photovoltaic assembly, etc., without limitation.

[0055] In this embodiment, the photovoltaic barrier 100 has a beam assembly 20 and at least one photovoltaic unit 10, wherein the beam assembly 20 has an upper beam assembly 21 and a lower beam assembly 22, and the upper beam assembly 21 and the lower beam assembly 22 cooperate with the column assembly 11 in the photovoltaic unit 10 to form the overall frame of the photovoltaic barrier 100, and the photovoltaic assembly 12 is installed on the frame.

[0056] Specifically, the column assembly 11 is connected between the upper beam assembly 21 and the lower beam assembly 22 to support the upper beam assembly 21 and the lower beam assembly 22, and the upper beam assembly 21 and the lower beam assembly 22 are arranged at vertical intervals, and the photovoltaic assembly 12 is clamped between the upper beam assembly 21 and the lower beam assembly 22.

[0057] In particular, the column assembly 11 is located at the position of the junction box on the photovoltaic assembly 12 and is provided with a mounting groove C1. The mounting groove C1 can cooperate with the upper beam assembly 21, the lower beam assembly 22 and the photovoltaic assembly 12 to accommodate the junction box in the photovoltaic assembly 12. In this way, the junction box on the photovoltaic assembly 12 is hidden, the risk of damage to the junction box is reduced, and the purpose of ensuring electrical safety is achieved.

[0058] In some optional embodiments, the column assembly 11 is located in the middle of the photovoltaic assembly 12 in the length direction.

[0059] It should be noted that the junction box of the existing standardized photovoltaic component 12 is located in the middle of the photovoltaic panel body, so the column component 11 is set in the middle of the photovoltaic component 12 to facilitate matching with the standardized photovoltaic component 12. In this way, there is no need to design non-standardized photovoltaic components 12, saving costs.

[0060] exist Figure 1 and Figure 2 In the embodiment shown, only one photovoltaic unit 10 is shown. It can be understood that when there are multiple photovoltaic units 10, they can be arranged along the length direction of the photovoltaic assembly 12. Figure 1 and Figure 2 In the illustrated embodiment, the other two photovoltaic units 10 on both sides of the central photovoltaic unit 10 have their photovoltaic components 12 hidden, and only their corresponding column components 11 are shown.

[0061] See also Figure 3In some optional embodiments, the column assembly 11 includes a fixed base 111 and a column 112 , and the mounting groove C1 is formed in the column 112 . The vertical ends of the mounting groove C1 and one side in the thickness direction of the photovoltaic assembly 12 are open.

[0062] The fixed base 111 is connected to the bottom end of the column 112 to cover the bottom opening of the mounting groove C1, the upper beam assembly 21 is connected to the top end of the column 112 to cover the top opening of the mounting groove C1, and the photovoltaic component 12 is attached to the column 112 on one side in the thickness direction of the photovoltaic component 12 to cover the opening of the mounting groove C1.

[0063] In this embodiment, the column assembly 11 includes a fixed base 111 and a column 112 . The column 112 is formed with the mounting groove C1 . Both vertical ends of the mounting groove C1 and one side in the thickness direction of the photovoltaic assembly 12 have openings.

[0064] It should be understood that the size of the opening of the mounting groove C1 on one side in the thickness direction of the photovoltaic module 12 is at least large enough to cover the junction box on the photovoltaic module 12. The fixed base 111 and the upper beam assembly 21 are respectively connected to the vertical ends of the column 112 and can just cover the vertical end openings of the mounting groove C1.

[0065] In addition, as can be seen from the above, the lower beam assembly 22 is connected to the bottom end of the column assembly 11. In this embodiment, the lower beam assembly 22 is connected to the fixed base 111 and connected to the column 112, so that the photovoltaic assembly 12 can fit as closely as possible to one side of the thickness direction of the column 112 to cover the opening.

[0066] In this way, all openings of the installation slot C1 are covered, so that the junction box is in a closed environment as much as possible, reducing the risk of damage to the junction box and ensuring electrical safety.

[0067] exist Figure 3 In the illustrated embodiment, the fixed base 111 is a square plate with base fixing holes H1 formed at its four corners. The base fixing holes H1 can be used in conjunction with screw connectors to fix the column assembly 11 on the ground.

[0068] Figure 4 It is a partial schematic diagram of the assembly of the lower beam assembly 22 and the column assembly 11 equipped with the photovoltaic assembly 12 according to one embodiment of the present application. Figure 5a for Figure 4 In some optional embodiments, the upper beam assembly 21 and / or the lower beam assembly 22 are formed with a wiring groove C2, which extends along the length direction and communicates with the installation groove C1.

[0069] exist Figure 5aIn the embodiment described, the lower crossbeam assembly 22 is formed with a wiring trough C2. This trough C2 accommodates the wires used to connect to the junction box, thereby concealing the wiring and ensuring electrical safety. It should be understood that the wiring trough C2 should be connected to the mounting slot C1 to ensure that the wires can enter the junction box in the mounting slot C1 through the wiring trough C2.

[0070] In another optional embodiment, the wiring groove C2 can also be formed in the upper beam assembly 21, that is, wiring is performed in the upper beam assembly 21. In another optional embodiment, both the upper beam assembly 21 and the lower beam assembly 22 are provided with a wiring groove C2, both of which can be used for wiring and achieve the purpose of hiding the wiring.

[0071] It should be noted that although the solution provided in this application uses the lower beam assembly 22 for routing, routing can also be performed in the upper beam assembly 21, or even in both the upper beam assembly 21 and the lower beam assembly 22. Technical personnel in this field can make adjustments according to actual needs.

[0072] Figure 5b Showed Figure 5a Schematic diagram of the lower cross beam 221 in the middle lower cross beam assembly 22. Figure 5c Showed Figure 5a Schematic diagram of the bracket 2221 in the middle lower crossbeam assembly 22. Figure 5d Showed Figure 5a Schematic diagram of the lower protection pad 2222 in the middle and lower cross beam assembly 22.

[0073] See also Figure 5a to Figure 5b In some optional embodiments, the lower crossbeam assembly 22 includes a lower crossbeam 221 and at least one bracket unit 222. The lower crossbeam 221 is formed with a wiring groove C2, and the bracket unit 222 is disposed in the wiring groove C2 and is provided with a bracket clamping groove C3 for clamping the photovoltaic module 12.

[0074] In this embodiment, the lower beam assembly 22 has at least a lower beam 221 and at least one bracket unit 222. The wiring groove C2 is formed in the lower beam 221, and the wiring groove C2 extends along the length direction of the lower beam 221. In addition, the bracket unit 222 is accommodated in the wiring groove C2 in the lower beam 221. The bracket unit 222 is formed with a bracket card slot C3, and the bracket card slot C3 can be clamped to the bottom side of the photovoltaic component 12 to fix the bottom side of the photovoltaic component 12.

[0075] In a further optional embodiment, the bracket unit 222 includes a bracket 2221 and a lower protection pad 2222. The bracket 2221 is formed with a bracket slot C3, and the lower protection pad 2222 is embedded in the bracket slot C3 and can be connected to both sides of the photovoltaic module 12 in the thickness direction.

[0076] In this embodiment, the bracket unit 222 is composed of at least a bracket 2221 and a lower protection pad 2222 . The bracket slot C3 is formed on the bracket 2221 . The lower protection pad 2222 is fixedly installed in the bracket slot C3 and is used to clamp the photovoltaic module 12 .

[0077] In other words, a lower protective pad 2222 is arranged in the bracket slot C2 in the bracket 2221, so that the bracket unit 222 is in flexible contact with the photovoltaic component 12 to avoid damage to the photovoltaic component 12. In addition, by arranging the lower protective pad 2222 in the bracket slot C3, the clamping size of the bracket slot C3 is reduced to be smaller than the thickness of the photovoltaic component 12, so that the bottom side of the photovoltaic component 12 can be clamped and fixed.

[0078] exist Figure 5d In the illustrated embodiment, the lower protective pad 2222 is adapted to the shape of the bracket slot C3 and is similar to a U-shape. In addition, the inner wall of the lower protective pad 2222 is formed with a tooth-like structure, which can increase the friction between the lower protective pad 2222 and the photovoltaic component 12, ensuring that the photovoltaic component 12 is firmly fixed and the risk of sliding of the photovoltaic component 12 is reduced.

[0079] In some optional embodiments, when there are multiple photovoltaic units 10, there are multiple bracket units 222, each photovoltaic component 12 is spliced along the length direction, and each photovoltaic component 12 corresponds to at least one bracket unit 222.

[0080] In this embodiment, when there are multiple photovoltaic units 10, each photovoltaic component 12 can be spliced or spaced apart in the length direction. In the case of spaced apart arrangement, glass panels can be set between two adjacent photovoltaic components 12, so that photovoltaic guardrails 100 of different styles can be formed.

[0081] In addition, in order to firmly fix the photovoltaic assembly 12 , there are multiple bracket units 222 and each photovoltaic assembly 12 corresponds to at least one bracket unit 222 .

[0082] for Figure 5a to Figure 5b The bracket units 222 shown in the figure are relatively short, so each photovoltaic module 12 corresponds to at least two bracket units 222, and the span between the support points formed by each bracket unit 222 and the photovoltaic module 12 must be sufficient to ensure the stability of the photovoltaic module 12 after being snapped in. It should be noted that in this case, the bracket units 222 can move within the wiring trough C2, making it easier for the assembler to adjust the distance between the bracket units 222, that is, to ensure that the span meets the requirements for stable support of the photovoltaic module 12.

[0083] Of course, when the length of the bracket unit 222 is long enough, each photovoltaic assembly 12 corresponds to one bracket unit 222 to achieve the purpose of stable support.

[0084] In a further optional embodiment, the bracket 2221 is formed with an avoidance groove C4, which is located on the opposite side of the bracket groove C3 and cooperates with the inner wall of the wiring groove C2 to form a wire passage P.

[0085] In this embodiment, bracket 2221 also features a clearance groove C4. When bracket 2221 is installed in wiring trough C2, clearance groove C4 is located below bracket retaining groove C3. Furthermore, the inner walls of clearance groove C4 and wiring trough C2 combine to form a wire passage P for the wires to pass through. In other words, clearance groove C4 in bracket 2221 is primarily designed to prevent obstruction of wiring.

[0086] In the illustrated embodiment, the bracket 2221 adopts a vertically symmetrical structure, and the avoidance groove C4 and the wiring groove C2 have the same shape, both similar to U-shaped grooves. Of course, the shape of the bracket 2221 is not limited to the illustrated embodiment and can be designed and adjusted according to needs.

[0087] Please combine Figure 4 and Figure 5a As shown, in some optional embodiments, the lower cross beam 221 is formed with a splicing notch D, and the splicing notch D can be embedded in part of the column assembly 11 and connect the wiring groove C2 with the installation groove C1.

[0088] In this embodiment, a splicing notch D is provided at the splicing position of the lower crossbeam 221 and the column assembly 11. The column assembly 11 is clamped through the splicing notch D, and the splicing notch D can also connect the wiring groove C2 with the installation groove C1.

[0089] In a specific application, the lower crossbeam 221 is connected to the fixed base 111 in the column assembly 11, and the splicing gap D accommodates the bottom end portion of the column 112 in the column assembly 11, so that the wiring groove C2 can be connected with the installation groove C1 in the column 112.

[0090] In the illustrated embodiment, the column assembly 11 is provided with a plurality of base lower beam connecting holes H2 arranged at intervals along the length direction of the lower beam 221, and the lower beam 221 is provided with a plurality of lower beam mounting holes H3 in the length direction. The lower beam mounting holes H3 can be aligned with the base lower beam connecting holes H2, and the lower beam 221 is connected to the fixed base 111 by screw connectors.

[0093] In this embodiment, the upper beam assembly 21 at least includes an upper beam 211 and an upper protection pad 212 . The upper beam 211 is provided with an upper clamping groove for clamping the top side of the photovoltaic assembly 12 .

[0094] An upper protective pad 212 is installed in the upper slot, which reduces the size of the upper slot and is smaller than the thickness of the photovoltaic component 12 , so that it can be connected to both sides of the photovoltaic component 12 in the thickness direction to achieve fixed installation of the top side of the photovoltaic component 12 .

[0095] In the illustrated embodiment, the upper slot is U-shaped, and the upper protective pad 212 is also U-shaped to match the upper slot. In specific applications, the upper protective pad 212 can cover the entire upper slot, or the upper protective pad 212 can be arranged in sections within the upper slot, which can be designed according to needs.

[0096] It should be noted that the conventional photovoltaic module 12 is further reinforced by gluing after being limited by the frame. However, in the present application, the main components of the upper crossbeam assembly 21 and the lower crossbeam assembly 22 that fix the photovoltaic module 12 are the upper protection pad 212 and the lower protection pad 2222, which respectively limit the vertical ends of the photovoltaic module 12. In other words, the existing gluing method is replaced by the upper protection pad 212 and the lower protection pad 2222, which is more convenient for assembly.

[0097] In the illustrated embodiment, the upper crossbeam 211 is a bent plate with an upper slot, and the upper slot is an ear plate section on one side in the thickness direction of the photovoltaic component 12. The ear plate section is used to cover the top opening of the column 112 and is provided with multiple upper crossbeam mounting holes H4.

[0098] The column 112 is provided with a column connecting hole H5 which is set vertically through. The upper beam mounting hole H4 can be aligned with the top part of the column connecting hole H5 and cooperate with the screw member to connect the upper beam 211 to the column 112.

[0099] Furthermore, the photovoltaic barrier 100 also includes a handrail buckle cover 30 , which is snap-connected to the upper crossbeam 211 and located above the upper crossbeam 211 .

[0100] In this embodiment, an additional handrail buckle cover 30 is buckled above the upper crossbeam 211 to cooperate with the upper crossbeam 211 to improve the overall strength, and also to play a decorative role, making the entire photovoltaic barrier 100 beautiful and elegant.

[0102] See also Figures 7a to 8b In some optional embodiments, the photovoltaic barrier 100 further includes an upper wall fixing member 40 and a lower wall fixing member 50 .

[0103] Upper wall fixing members 40 are provided at both ends of the upper beam assembly 21 in the length direction for connecting to the wall; lower wall fixing members 50 are provided at both ends of the lower beam assembly 22 in the length direction for connecting to the wall.

[0104] In this embodiment, the ends of the upper crossbeam assembly 21 are connected to the wall via upper wall fixings 40, and the ends of the lower crossbeam assembly 22 are connected to the wall via lower wall fixings 50. As can be seen from the foregoing, the fixing base 111 of the column assembly 11 can be connected to the ground, so that the frame formed by the upper crossbeam assembly 21, the lower crossbeam assembly 22 and the column assembly 11 can be fixed in a desired position.

[0105] In the illustrated embodiment, both the upper wall fixture 40 and the lower wall fixture 50 are formed from a short section of angle steel and are provided with a plurality of upper fixture mounting holes H6 and a plurality of lower fixture mounting holes H7, respectively. The upper fixture mounting holes H6 engage screws to connect the upper wall fixture 40 to the upper crossbeam 211 and the wall, respectively.

Figure 9 In some optional embodiments, the fixed base 111 is provided with a column limiting groove C5 and a lower beam guide groove C6. The column limiting groove C5 is used to accommodate the bottom end of the column 112, and the lower beam guide groove C6 is used to limit the lower beam assembly 22.

[0107] In this embodiment, the bottom end of the column 112 can be inserted into the column limiting groove C5, and the lower beam 221 in the lower beam assembly 22 can slide into the lower beam guide groove C6 along its length direction, which is convenient for assemblers to assemble.

[0108] In the illustrated embodiment, the fixed base 111 is provided with a plurality of base column mounting holes H8. These holes H8 are disposed within the column limiting grooves C5 and are aligned one-to-one with the plurality of column connection holes H5 in the columns 112. Screws are used to connect the fixed base 111 to the columns 112. Furthermore, the plurality of base lower crossbeam connection holes H2 are all located within the lower crossbeam guide grooves C6.

[0109] It should be noted that for the upper beam 211 in the upper beam assembly 21 and the lower beam 221 in the lower beam assembly 22, if the installation space is limited, these beams do not need to have a long length. In this way, splicing interfaces can be directly processed on the upper beam 211 and the lower beam 221 to match the column assembly 11. The splicing interface of the upper beam 211 refers to the upper beam mounting hole H4 set thereon, and the splicing interface of the lower beam 221 refers to the lower beam mounting hole H3 and the splicing notch D set thereon.

[0110] If the installation space is large and these beams are designed to be too long, it will cause transportation difficulties. Therefore, the upper beam 211 and the lower beam 221 both adopt a multi-section splicing structure, that is, the upper beam 211 is composed of multiple upper beam sections spliced in the length direction, and the lower beam 221 is composed of multiple lower beam sections spliced in the length direction.

[0111] Moreover, the joint of the upper crossbeam 211 is formed at the joint of two adjacent upper crossbeam sections, and the joint of the two adjacent upper crossbeam sections is exactly where the column assembly 11 is located. The joint of the lower crossbeam 221 is formed at the joint of two adjacent lower crossbeam sections, and the joint of the two adjacent lower crossbeam sections is exactly where the column assembly 11 is located.

[0112] It can be seen that the upper crossbeam 211 and the lower crossbeam 221 can adopt an integral structure or a multi-section spliced structure, which can be selected according to the installation environment.

[0113] It should be noted that the upper crossbeam 211, the lower crossbeam 221 and the columns 112 provided in the present application can all be made of aluminum alloy profiles, which can reduce the weight while ensuring sufficient strength.

[0114] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Those skilled in the art can change, modify, replace and modify the above embodiments within the scope of the present application.
