Description

Technical Field

[0001] This invention relates to the field of photovoltaic fence technology, and in particular to a photovoltaic fence. Background Technology

[0002] Guardrails primarily serve to isolate and differentiate areas, providing safety warnings, and are widely used in agriculture, industry, and construction. Sound barriers, also known as noise walls, soundproof screens, or soundproof barriers, are currently mainly used in transportation and municipal facilities such as highways, elevated roads, and urban light rail and subway systems for noise reduction and control of traffic noise impacting nearby urban areas. They can also be used in factories and other noise source areas for noise reduction. Solar photovoltaic sound barriers are a new type of sound barrier that combines traditional sound barrier technology with photovoltaic solar power generation technology. Balcony railings are aesthetic and protective facilities for the outer edge of balconies, constructed from alloy tubing through welding or assembly. Common low window sills are about 0.5 meters from the ground; adding a 0.4-meter railing or fence close to the inner wall will certainly meet the required protective measures.

[0003] With the rapid development of photovoltaic new energy, technological advancements, increased efficiency, and reduced costs, "photovoltaic fences" have emerged. In Europe, the decline in photovoltaic prices has led some households to use these products in innovative ways. For example, some families have shared on social media that they use solar panels erected as garden fences, capturing less sunlight and electricity but saving on expensive installation costs.

[0004] Current photovoltaic (PV) fence designs primarily involve directly replacing the sound insulation panels or fence panels on the original fence's flat panel components and mounting them onto the frame posts, or installing PV-type sound barriers atop steel columns. However, due to structural limitations, existing PV fences often have side posts higher than the modules, resulting in shading under oblique sunlight and low actual solar energy conversion efficiency. Furthermore, PV module installation mainly relies on clamps or bolts, which not only involves numerous components but also presents a complex and inconvenient installation process. Summary of the Invention

[0005] This invention provides a photovoltaic fence that effectively improves the installation stability of the fence while preventing dust accumulation on the front of the laminated components, thereby improving the power generation efficiency of the photovoltaic fence. The photovoltaic fence includes posts, module frames, and photovoltaic laminated components, wherein:

[0006] The columns are arranged at equal intervals, and at least one photovoltaic laminate is provided between two adjacent columns;

[0007] The component frame is disposed on the outside of the photovoltaic laminate, including two horizontal frame frames and two vertical frame frames; the two vertical frame frames are respectively disposed on the two vertical sides of the photovoltaic laminate, one side of the vertical frame frame can be connected to the column, and the other side is provided with a latch, which engages with the vertical side of the photovoltaic laminate; the two horizontal frame frames are respectively disposed on the two horizontal sides of the photovoltaic laminate, and the horizontal frame frames are L-shaped to connect to the back surface and the horizontal side surface of the photovoltaic laminate.

[0008] In a specific implementation, a connecting groove is provided on the side of the vertical frame that connects to the column. The connecting groove matches the shape of the column, and the vertical frame is secured to the column through the connecting groove.

[0009] In practice, the column is a cylindrical column and the connecting groove is a semi-circular connecting groove.

[0010] In specific implementation, the B-side of the horizontal frame is designed in a wavy shape.

[0011] In practice, the photovoltaic laminate is sealed to the vertical frame and the horizontal frame using sealant.

[0012] In specific implementation, a first overflow groove is provided on both sides of the bayonet opening; a second overflow groove is provided at the connection between the horizontal frame and the back and horizontal edge of the photovoltaic laminate.

[0013] In a specific implementation, multiple photovoltaic laminates are provided between two adjacent columns, and the multiple photovoltaic laminates are arranged sequentially along the extension direction of the columns.

[0014] In practice, the gaps between the component frames of two adjacent photovoltaic laminates are filled with silicone or silicone strips.

[0015] In practice, the thickness of the component frame is 10mm to 20mm.

[0016] In practice, the photovoltaic laminate is placed horizontally or vertically between two adjacent columns.

[0017] The photovoltaic fence provided by this invention includes posts, module frames, and photovoltaic laminates. Multiple posts are arranged at equal intervals, with at least one photovoltaic laminate between adjacent posts. The module frames are located on the outside of the photovoltaic laminates and include two horizontal frames and two vertical frames. The two vertical frames are respectively located on the two vertical sides of the photovoltaic laminate, with one side of each frame connectable to a post and the other side having a latch that engages with the vertical side of the photovoltaic laminate. The two horizontal frames are respectively located on the two horizontal sides of the photovoltaic laminate, and are L-shaped to fit snugly against the back and side surfaces of the photovoltaic laminate. This photovoltaic fence directly fixes the photovoltaic laminate to the posts via the frames. Compared to conventional bolt and clamp installation, this method is not only more convenient but also offers higher stability. The L-shaped horizontal frames do not obstruct the front of the photovoltaic laminate, preventing dust accumulation and the resulting hot spot effect. This improves the lifespan of the photovoltaic laminate and effectively enhances its power generation efficiency. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of the specific embodiments of the present invention clearer, the specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Here, the illustrative specific embodiments and their descriptions are used to explain the present invention, but are not intended to limit the present invention.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this invention provides a photovoltaic fence that effectively improves the installation stability of the fence while preventing dust accumulation on the front of the laminate, thereby improving the power generation efficiency of the photovoltaic fence. The photovoltaic fence includes a post 100, a module frame 200, and a photovoltaic laminate 300, wherein:

[0026] Multiple columns 100 are arranged at equal intervals, and at least one photovoltaic laminate 300 is provided between two adjacent columns 100;

[0027] The component frame 200 is disposed on the outside of the photovoltaic laminate 300, including two horizontal frame frames 220 and two vertical frame frames 210; the two vertical frame frames 210 are respectively disposed on the two vertical sides of the photovoltaic laminate 300, the vertical frame frames 210 can be connected to the column 100, and a snap-fit ​​211 is provided on the other side, the snap-fit ​​211 engages with the vertical side of the photovoltaic laminate 300; the two horizontal frame frames 220 are respectively disposed on the two horizontal sides of the photovoltaic laminate 300, the horizontal frame frames 220 are L-shaped, so as to fit and connect to the back and horizontal side surface of the photovoltaic laminate 300.

[0028] In practice, the connection between the vertical frame 210 and the column 100 can have multiple implementation schemes, for example, Figure 1 , Figure 2 , Figure 3 As shown, a connecting groove 212 can be provided on the side of the vertical frame 210 that connects to the column 100. The connecting groove 212 matches the shape of the column 100, and the vertical frame 210 can be secured to the column 100 through the connecting groove 212.

[0029] Furthermore, the shape of the column 100 can be implemented in various ways. For example, the column 100 can be a cylindrical column, a square column, or an elliptical column. Further, such as... Figure 3 As shown, when the column 100 is a cylindrical column, the corresponding connecting groove 212 can be a semi-circular connecting groove. Furthermore, when fixing the vertical frame 210 through the connecting groove 212, silicone can be applied inside the connecting groove 212, which can enhance the connection stability and also play a sealing role.

[0030] The frame 200 of the component is fixed on the column 100 by the connecting groove 212. Compared with the traditional installation method of installing the frame on the column 100 by clamping blocks or bolts, it can effectively save the cost of clamping blocks and bolts, and has excellent sealing and stability.

[0031] In practice, the shape of the B-side of the horizontal frame 220 can be implemented in various ways. For example, a protruding structure can be provided on the B-side of the horizontal frame 220; furthermore, such as... Figure 4 As shown, the B-side of the horizontal frame 220 is wavy. The wavy B-side of the horizontal frame 220 allows the component frames 200 of two adjacent photovoltaic laminates 300 to rub against each other when multiple photovoltaic laminates 300 are stacked between two columns 100, thereby buffering stress; at the same time, it can also play a role in ventilation and pressure reduction in scenarios where ventilation is required.

[0032] In specific implementations, the connection between the photovoltaic laminate 300 and the vertical frame 210 and the horizontal frame 220 can have various implementation schemes. For example, the photovoltaic laminate 300 can be sealed to the vertical frame 210 and the horizontal frame 220 using sealant. Furthermore, the sealant can be silicone sealant. The use of silicone sealant not only ensures a stable connection but also effectively improves sealing performance.

[0033] Furthermore, in order to effectively improve the connection stability between the photovoltaic laminate 300 and the vertical frame 210 and the horizontal frame 220, such as Figure 3 and Figure 4 As shown, a first overflow groove 213 is provided on both sides of the bayonet 211; a second overflow groove 222 is provided at the connection between the horizontal frame 220 and the back and horizontal edge of the photovoltaic laminate 300.

[0034] In practice, the number of photovoltaic laminates 300 between two adjacent columns (100) can be configured in various ways. For example, such as... Figure 1 As shown, multiple photovoltaic laminates 300 can be provided between two adjacent columns 100, and the multiple photovoltaic laminates 300 are arranged sequentially along the extension direction of the column 100. Specifically, the number of photovoltaic laminates 300 is determined according to the design height of the photovoltaic fence.

[0035] In specific implementations, the gap between the component frames 200 of two adjacent photovoltaic laminates 300 can be configured in various ways. For example, in a sound barrier scenario, a photovoltaic fence is needed to block sound. Therefore, the gap between the component frames 200 of two adjacent photovoltaic laminates 300 can be filled with silicone or silicone strips.

[0036] In practice, the thickness of the component frame 200 can be implemented in various ways. For example, considering that existing photovoltaic fences mostly use traditional ground-mounted photovoltaic modules, the design of these modules needs to take into account the impact of snow load, thus the module thickness is 30mm or 35mm. However, the application scenario of photovoltaic fence facades does not require much consideration of snow load requirements, so a lightweight design can be adopted in the component thickness design, and the component frame 200 can be thinned, with a thickness of 10mm to 20mm. Compared with traditional frames, the thickness is reduced to 10-20mm on the basis of the traditional 30mm or 35mm thick frame, resulting in an overall reduction of about 30%, which can effectively reduce the material cost of metal frames.

[0037] In specific implementations, the connection between the horizontal frame 220 and the vertical frame 210 can have various implementation schemes. For example, as... Figure 5 As shown, the horizontal frame 220 and the vertical frame 210 are joined at a 45° angle. These two 45° angled joints ensure a 90° angle at the joint, preventing material waste. Furthermore, to effectively ensure the stability of the connection, the joint can be fixedly connected using corner brackets 230. In addition, the horizontal frame 220 and vertical frame 210 of this component frame 200 can be pre-assembled with the photovoltaic laminate 300 at the factory using a framing machine.

[0038] In practice, the photovoltaic laminate 300 can be selected in various ways. For example, the photovoltaic laminate 300 can be a bifacial solar cell laminate, and both the front and back sides of the bifacial solar cell laminate can be encapsulated with high-transparency glass.

[0039] In practice, the photovoltaic laminate 300 can be positioned in various ways. For example, the photovoltaic laminate 300 can be placed horizontally or vertically between two adjacent columns 100 as needed. Correspondingly, the installation spacing of the columns 100 is predetermined based on whether the photovoltaic laminate 300 is placed horizontally or vertically.

[0040] The photovoltaic fence provided by this invention combines photovoltaic power generation with the function of fencing for isolation and division of land plots. It is applicable to farms, gardens, transportation, and construction sites, with a wide range of applications. It achieves convenient living while meeting the demand for green energy. This photovoltaic fence uses high-efficiency bifacial cells, encapsulated with high-transparency glass on both sides, providing bifacial power generation. It is designed to improve photovoltaic power generation conversion efficiency and reduce LCOE while adhering to traditional fence safety standards. The component frame 200 structure has been improved with connecting grooves 212 on the sides. The components can be directly secured to the posts 100 using these grooves, allowing for single-piece or stacked installation, making installation simpler and more convenient. To further increase power generation on the front of the photovoltaic laminate 300, the front of the photovoltaic laminate 300 features a dust-proof, A-side-less design, effectively solving the problem of dust accumulation on photovoltaic modules and improving aesthetics.

[0041] In summary, the photovoltaic fence provided by the present invention includes posts 100, module frames 200, and photovoltaic laminates 300, wherein: multiple posts 100 are arranged at equal intervals, and at least one photovoltaic laminate 300 is provided between two adjacent posts 100; the module frames 200 are provided on the outside of the photovoltaic laminates 300, including two horizontal frames 220 and two vertical frames 210; the two vertical frames 210 are respectively provided on the two vertical sides of the photovoltaic laminates 300, and the vertical frames 210 can be connected to the posts 100, and a latch 211 is provided on the other side, which engages with the vertical side of the photovoltaic laminates 300; the two horizontal frames 220 are respectively provided on the two horizontal sides of the photovoltaic laminates 300, and the horizontal frames 220 are L-shaped to fit and connect to the back and horizontal side surfaces of the photovoltaic laminates 300. The photovoltaic fence directly fixes the photovoltaic laminate 300 to the column 100 through the frame. Compared with conventional bolt and clamp installation, it is not only easier to install, but also has higher stability. The L-shaped horizontal frame 220 does not obstruct the front of the photovoltaic laminate 300, thus avoiding dust accumulation on the front of the photovoltaic laminate 300 and the hot spot effect caused by dust accumulation. This not only improves the service life of the photovoltaic laminate 300, but also effectively improves the power generation efficiency of the photovoltaic laminate 300.
