[0072] Northwest my country has extensive highway routes and vast mileage, offering significant potential for photovoltaic development. In particular, the anti-glare panels and nets used in the middle of highway subgrades offer significant potential for development if they can be integrated with photovoltaic power generation. However, the inventors discovered that current anti-glare panels are primarily made of metal or plastic, which have limited functionality and are difficult to integrate with photovoltaic power generation.

[0073] Now combined Figures 1 to 13 , various embodiments provided by the present invention are described. It should be understood that the following are merely illustrative embodiments of the present invention and do not constitute any particular limitation to the present invention.

[0074] Figure 1 This is one of the structural schematic diagrams of the photovoltaic anti-glare panel assembly provided by the present invention; Figure 2 This is the second structural diagram of the photovoltaic anti-glare panel assembly provided by the present invention; Figure 3 A schematic side view of the photovoltaic anti-glare panel assembly provided by the present invention; Figure 4 This is a schematic diagram of the planar structure of the bottom of the photovoltaic base provided by the present invention; Figure 5 This is a front view structural diagram of the photovoltaic anti-glare panel assembly provided by the present invention; Figure 6 This is a partial structural diagram of the photovoltaic anti-glare panel assembly provided by the present invention. Figures 1 to 6 A photovoltaic anti-glare panel assembly 100 is provided. It is designed to be installed in the central median 2000 of a highway roadbed 5000. It can prevent glare from oncoming vehicles during nighttime driving. The photovoltaic anti-glare panel assembly 100 includes a photovoltaic anti-glare panel 110, a frame 120, a fixing unit 130, and a power unit.

[0075] The frame 120 is mounted around the periphery of the photovoltaic anti-glare panel 110, securing the panel 110. A fixing unit 130 is provided at the bottom of the frame 120 and is connected to the ground, thereby securing the photovoltaic anti-glare panel 110. Furthermore, the power unit is disposed within the fixing unit 130, which also provides protection for the power unit.

[0076] The photovoltaic anti-glare panel 110 includes a double layer of tempered glass and a plurality of solar cells 111 disposed between the double layers of tempered glass. The solar cells 111 absorb solar energy and generate electricity from it. The double layers of tempered glass secure and protect the solar cells 111. Power consumption units are electrically connected to each of the plurality of solar cells 111 and are configured to transmit or utilize the received electrical energy.

[0077] The photovoltaic anti-glare panel assembly 100 provided by the present invention utilizes solar cells 111 within a photovoltaic anti-glare panel 110, thereby reducing glare from oncoming vehicles while also fully utilizing solar energy for photovoltaic power generation, providing green electricity and contributing to carbon neutrality in the transportation system. Furthermore, the modular structure of the photovoltaic anti-glare panel assembly 100 facilitates installation, replacement, and maintenance, making it suitable for implementation and widespread adoption.

[0078] Figure 7 For a schematic diagram of another photovoltaic anti-glare assembly provided by the present invention, see Figure 7 The photovoltaic anti-glare panel 110 can be a rectangular parallelepiped, arranged vertically to avoid occupying a large bottom surface area while having sufficient area for power generation. For example, the photovoltaic anti-glare panel 110 is a rectangular structure with a width of 20-25 cm, a height of 90-100 cm, and a thickness of 0.5-1.5 cm. For another example, the characteristics of the photovoltaic anti-glare panel can also be: a length of 1.5-2.0 m, a height of 0.8-1.0 m, and a width of 0.5-1.5 cm.

[0079] The frame 120 may be made of aluminum alloy, which has advantages such as lightness, high strength, and corrosion resistance. The aluminum alloy frame 120 is disposed around the photovoltaic anti-glare panel 110 and has a width of 1-2 cm. The frame 120 completely surrounds the photovoltaic anti-glare panel 110, securing and protecting the photovoltaic anti-glare panel 110.

[0080] In one embodiment of the present invention, the power consumption unit includes a junction box and a power transmission line. The solar panel is connected via the junction box, and the power transmission line is connected to the junction box.

[0081] Correspondingly, the fixing unit 130 includes: a base 131, a support portion 132, and a column 133, arranged in order from top to bottom. The base 131 is located at the bottom of the frame 120 to support the frame 120. Furthermore, a rectangular groove 1311 is reserved at the center of the bottom end of the base 131, and a junction box is located in this groove 1311.

[0082] Furthermore, an insulating film is provided on the inner side of the groove 1311 to prevent it from conducting electricity and ensure the safety of electricity use. Furthermore, the base 131 has a built-in wire channel to connect the junction box to the photovoltaic anti-glare panel 110 through wires. The surface of the wire channel is provided with an insulating film to prevent it from conducting electricity. Furthermore, the bottom of the base 131 is 0.7-1.0m above the road surface of the roadbed 5000. Furthermore, only one base 131 with a groove 1311 is provided for each photovoltaic anti-glare panel 110, while the other base 131 is not provided with a groove.

[0083] The base 131 has two screw holes 1312 on either side of the central axis in the X and Y directions on both sides of the photovoltaic anti-glare panel 110. Bolts 1313 are provided in each of the screw holes. Bolts 1313 are used to secure the base 131 to the lower support portion 132. The bolts 1313 are stainless steel hexagon socket head bolts. In other embodiments, the bolts 1313 may be stainless steel hexagon socket head bolts.

[0084] The above-mentioned support portion 132 is arranged at the bottom of the base 131. Moreover, the support portion 132 is long and strip-shaped, and is used to be set along the road. A transmission line is provided in the inner cavity of the support portion 132, and the transmission line is connected to the junction box. The junction box and the transmission line can transmit the electric energy provided by the solar panel for independent use such as energy storage, batteries, and charging piles, and can also be connected to the power grid for grid-connected power transmission. Specifically, the inner wall of the internal cavity 1321 of the support portion 132 is provided with an insulating film to form an insulating space, in which wires and cables are connected. The top of the support portion 132 is provided with a wire channel, which can connect the wires of the junction box at the bottom end of the base 131. The wires are gathered and connected inside the support portion 132 through the wire channel, and eventually lead to devices such as batteries, junction boxes, and inverters.

[0085] Furthermore, support sections 132 are positioned along the centerline of the highway, with photovoltaic anti-glare panels 110 positioned every 1.2-1.5 meters. These support sections 132 are made of stainless steel and are elongated. The photovoltaic anti-glare panels 110 are positioned parallel to the highway's direction 002. The support sections 132 have a rectangular cross-section and a hollow interior. For example, the width of the support sections 132 is 2-3 cm greater than the width of the photovoltaic anti-glare panels 110, at 22-28 cm.

[0086] The aforementioned columns 133 are located at the bottom of the support portion 132 and are secured to the ground. These columns 133 can be made of galvanized aluminum steel pipes, for example, with a diameter of 15-25 cm. Their bottoms are fixed below the road surface, 0.5-0.8 m above the surface and 0.6-1.0 m below the surface. The spacing between adjacent columns 133 is 2.5-3.5 m. Furthermore, the columns 133 are located at the centerline of the median 2000 of the highway roadbed 5000.

[0087] In an embodiment provided by the present invention, the heights of the two sides of the base 131 are lower than the height in the middle, and the middle of the base 131 is connected to the frame 120 .

[0088] Specifically, the base 131 is also made of aluminum alloy, and its width is the same as that of the photovoltaic anti-glare panel 110. It is symmetrically distributed along the X and Y directions on both sides of the photovoltaic anti-glare panel 110. The base 131 presents an arc from high to low along the bottom of the photovoltaic anti-glare panel 110 to the edge of the base 131, which makes it easier for rainwater on the photovoltaic anti-glare panel 110 to flow down and drain more smoothly without stagnation, thus protecting the safety of the photovoltaic anti-glare panel. Figure 3 As can be seen, the base 131 has a nearly semi-elliptical structure. Two bases 131 are disposed at the bottom of each aluminum alloy frame 120, arranged symmetrically on both sides. For example, the width of the base 131 can be 15-20 cm, and the bottom of the base 131 can be 0.7-1.0 m above the roadbed 5000 surface.

[0089] In the above embodiment, a sealing card is provided in base 131. This sealing card seals against the outside of the junction box, isolating recess 1311 from the outside to protect the junction box. Furthermore, the sealing card is made of an insulating material and is flush with the base 131. The sealing card is removable, facilitating easy installation and removal.

[0090] In an embodiment provided by the present invention, the plurality of solar cells 111 are arranged at intervals in two directions perpendicular to each other, and a preset distance exists between two adjacent solar cells 111 .

[0091] Please continue to see Figure 7 Taking the solar cell 111 as an example, the solar cells 111 in the photovoltaic anti-glare panel 110 can be arranged with staggered intervals. The preset interval can be smaller than the width of the solar cell 111, which has a higher power generation efficiency. Alternatively, the preset interval can be equal to the width of the solar cell 111, which can effectively ensure the transmittance of the photovoltaic anti-glare panel 110, meeting the two-way visual safety requirements of two-way vehicles, while also being able to reduce the glare of oncoming vehicles. For example, the solar cells 111 are arranged in a matrix, with a blank space of 5-10 cm between each solar cell 111, so that a suitable transmittance can be achieved.

[0092] Figure 8 For a schematic diagram of the assembly structure of a photovoltaic anti-glare component provided by the present invention, please refer to Figure 8 Multiple photovoltaic anti-glare panel assemblies 100 can be connected for use. Specifically, the support portions 132 of each photovoltaic anti-glare panel assembly 100 are connected to each other, and the distance between the corresponding photovoltaic anti-glare panels 110 is 20-30 cm. This structure can not only reduce the glare of oncoming vehicles, but also prevent eye fatigue.

[0093] Figure 9 A schematic structural diagram of another photovoltaic anti-glare panel provided by the present invention; Figure 10 This is a schematic diagram of the structure of another photovoltaic anti-glare panel provided by the present invention. Figures 9 and 10 In one embodiment provided by the present invention, the solar cell 111 is square or diamond-shaped. For example, the photovoltaic anti-glare panel 110 in the photovoltaic anti-glare panel assembly 100 is diamond-shaped, with a pointed top, a diamond-shaped middle, and a base 131 at the bottom. During use, the shape can be selected according to needs, and this embodiment does not limit this. For example, the solar cell 111 is square with a side length of 15-20 cm.

[0094] In one embodiment provided by the present invention, the end of the solar cell 111 has a beveled edge, which can meet different needs in practical applications, save materials, prevent glare, and generate sufficient electricity.

[0095] Other advantages of the photovoltaic anti-glare panel assembly 100 provided in this embodiment are mainly reflected in:

[0096] (1) It has strong scalability, excellent comprehensive functions, rich application scenarios, and strong applicability, and is applicable to different roadbed conditions.

[0097] (2) It is easy to clean and maintain in the later stage and has strong practicality.

[0098] In one embodiment of the present invention, solar cell 111 has power generation areas on both sides, ensuring visual consistency for vehicles traveling on both sides of the highway while also providing power generation on both sides. This makes it suitable for roads of various orientations and offers high applicability. Specifically, solar cell 111 utilizes polycrystalline silicon or monocrystalline silicon.

[0099] In one embodiment of the present invention, the double-layer tempered glass is made of cadmium telluride double-sided solar power generation glass. Cadmium telluride double-sided solar power generation glass is a solar power generation module formed by fusing highly transparent tempered glass with cadmium telluride thin film material, offering advantages such as high strength and high power generation efficiency.

[0100] In an embodiment provided by the present invention, a light-emitting unit is provided on the frame 120 , and the light-emitting unit is electrically connected to the power-consuming unit.

[0101] Specifically, the light-emitting unit can be a colored lamp, which is powered by a battery stored in the photovoltaic anti-glare panel assembly 100 and is set to an automatic switch, which provides a flash or indicator light function, which is in an open state during the night and in an closed state during the day. In this way, the photovoltaic anti-glare panel 110 can provide indicator light and safety guidance for vehicles driving at night.

[0102] In one embodiment provided by the present invention, the above-mentioned frame 120 is also provided with materials such as a luminescent film, a light-storing film, a reflective film or a fluorescent film, which can emit a faint light or reflect a faint light at night, which can provide indicator lights and safety guidance for vehicles traveling at night. Furthermore, the photovoltaic anti-glare panel assembly 100 provided by the present invention is affected by outdoor dust, rain, snow, bird droppings, etc. for a long time, and dust and stains will form on its surface, which will seriously reduce the power generation efficiency of the photovoltaic anti-glare panel assembly 100, and it needs to be regularly dusted and cleaned. Specifically, a vehicle equipped with a water tank is used, a micro-pressure water gun is set, and close-range cleaning is adopted. For stubborn stains, a handheld rotary brush can be used for cleaning, and the use of high-pressure tools such as high-pressure water guns can be avoided to prevent damage to the photovoltaic anti-glare panel 110. In particular, the frequency of cleaning needs to be increased during the windy and sandy season in desert areas.

[0103] Furthermore, if the photovoltaic anti-glare panel assembly 100 provided by the present invention is physically damaged or has a broken circuit, it needs to be repaired and replaced in a timely manner to maintain the stable operation of the entire photovoltaic power generation system 1000.

[0104] The present invention also provides a photovoltaic power generation system. Figure 11 For a schematic diagram of the photovoltaic power generation system provided by the present invention, please refer to Figure 11 The photovoltaic power generation system 1000 includes any one of the above-mentioned photovoltaic anti-glare panel assemblies 100, a DC busbar device, and a DC power distribution device.

[0105] The photovoltaic anti-glare panel assembly 100 is arranged on the central dividing strip 2000 .

[0106] The DC busbar connects multiple photovoltaic anti-glare panel assemblies 100 in series. Specifically, in this photovoltaic power generation system 1000, multiple photovoltaic anti-glare panel assemblies 100 form multiple series groups, which are then connected in parallel to the DC busbar. The DC busbar ensures orderly connection and convergence of the photovoltaic anti-glare panel assemblies 100.

[0107] The DC power distribution device is electrically connected to the DC bus device. The DC power distribution device is used to shunt the DC power passing through the DC bus device and can monitor and protect each shunt DC power.

[0108] In one embodiment of the present invention, the photovoltaic power generation system 1000 further includes an inverter and an AC power distribution device. Specifically, the inverter is electrically connected to the DC power distribution device, converting the DC power diverted by the DC power distribution device into AC power for subsequent use. The AC power distribution device is electrically connected to the inverter, controlling, distributing, and monitoring the AC power passing through the inverter based on the specific needs of the user end.

[0109] The user end corresponding to the photovoltaic power generation system 1000 includes two types according to the type of use. One is an independent system, such as batteries and energy storage, which charges the batteries and energy storage with the current of the AC distribution device to provide power supply and achieve power consumption; the other is to connect the current of the AC distribution device to the power grid for grid-connected power transmission, thereby achieving power transmission.

[0110] Furthermore, the photovoltaic power generation system 1000 relies on a photovoltaic pavement, the surface of which is made of a light-transmitting, high-strength glass material with load-bearing capacity, and has built-in single-sided photovoltaic panels that can convert solar radiation received by the pavement into electricity.

[0111] The advantages of the photovoltaic power generation system 1000 provided in this embodiment are mainly reflected in:

[0112] (1) Combining the photovoltaic anti-glare panel assembly 100 with the photovoltaic power generation system 1000 is a new type of photovoltaic power generation system 1000 that can fully utilize the abundant solar energy resources of the national highway network and provide a new model for the development of national green capabilities.

[0113] (2) The photovoltaic power generation system 1000 relies on the highway route and also provides green capabilities for the highway system and vehicles, promoting the low-carbon transformation of the highway transportation system.

[0114] In one embodiment provided by the present invention, the setting direction 001 of the photovoltaic anti-glare panel 110 is perpendicular or parallel to the direction 002 of the highway.

[0115] There are various configuration methods for the photovoltaic power generation system 1000 provided in this embodiment, depending on the application scenario. The following example is provided with reference to the direction of a highway.

[0116] (1) On a highway 002 with a north-south orientation, on the central dividing strip 2000 of the highway, photovoltaic anti-glare panel assemblies 100 are mainly arranged parallel to the highway orientation, supplemented by photovoltaic anti-glare panel assemblies 100 perpendicular to the highway orientation, and the length ratio of the two is set in the range of 10:1-10:2.

[0117] Furthermore, photovoltaic anti-glare panels 110 are arranged at intervals of 20-30 cm on the support portion 132. For example, photovoltaic anti-glare panel assemblies 100 can be arranged parallel to the road along a 10-20 km route, and photovoltaic anti-glare panel assemblies 100 can be arranged perpendicular to the road along a 1-2 km route. This staggered arrangement improves power generation efficiency and prevents visual fatigue.

[0118] Because the main highway runs north-south, its route 002 is essentially perpendicular to solar radiation. This means that one side of the photovoltaic anti-glare panel assembly 100 is perpendicular to the solar radiation, maximizing solar radiation reception and thereby increasing solar radiation conversion per unit of road mileage. Furthermore, staggering the two types of photovoltaic anti-glare panels adjusts the field of view and prevents visual fatigue. Furthermore, because the photovoltaic anti-glare panel assemblies 100 face different orientations, their exposure duration, intensity, and power generation efficiency per unit of road mileage vary. Combining the two effectively extends the photovoltaic power generation system 1000's power generation capacity and duration, while also making the power generation efficiency more stable and weather-resistant.

[0119] (2) On a highway 002 with an east-west orientation, on the central dividing strip 2000 of the highway, photovoltaic anti-glare panel assemblies 100 are mainly arranged perpendicular to the highway orientation, supplemented by photovoltaic anti-glare panel assemblies 100 arranged parallel to the highway orientation, and the length ratio of the two is set in the range of 10:4-10:6.

[0120] Furthermore, photovoltaic anti-glare panels 110 are arranged at intervals of 20-30 cm on the support portion 132. For example, photovoltaic anti-glare panel assemblies 100 can be arranged perpendicular to the direction of the road along a 10-20 km route, and photovoltaic anti-glare panel assemblies 100 can be arranged parallel to the direction of the road along a 5-10 km route. Such staggered arrangement of the two can improve power generation efficiency and prevent visual fatigue.

[0121] Because the main highway is east-west, its direction is basically perpendicular to the solar radiation, and the photovoltaic anti-glare panel assembly 100 has one side facing south, which can receive direct solar radiation throughout the day, and the photovoltaic anti-glare panel assembly 100 has two sides that can receive solar radiation at different times, one side before 12:00 local time and the other side after 12:00 local time. Compared with the cost per unit distance of the two components, combining the two can not only reduce costs, but also improve the efficiency of photovoltaic power generation.

[0122] At the same time, the two types of photovoltaic anti-glare panels are staggered to adjust the field of vision and prevent visual fatigue. On the other hand, the photovoltaic anti-glare panel assembly 100 has different photovoltaic duration, intensity, and power generation efficiency per unit road mileage due to its different orientation. Combining the two can effectively extend the power generation and power generation time of the photovoltaic power generation system 1000, and make the power generation efficiency more stable and weather-resistant.

[0123] The advantages of the photovoltaic power generation system 1000 provided in this embodiment are mainly reflected in:

[0124] (1) The two types of photovoltaic anti-glare panel assemblies 100 have different structural characteristics, especially different orientations, photovoltaic reception time, intensity, and power generation efficiency per unit road mileage. For different road route directions 002, photovoltaic anti-glare panel assemblies 100 with different directions are set, and the two are combined to effectively extend the power generation and power generation time of the photovoltaic power generation system 1000, and make the power generation efficiency more stable and weather-resistant.

[0125] (2) The photovoltaic anti-glare panel assemblies 100 in two different orientations are staggered and mixed to adjust the driver's field of vision, prevent visual fatigue, and contribute to safe driving.

[0126] The present invention also provides a photovoltaic roadbed system, Figure 12 A schematic diagram of the top view of the photovoltaic roadbed system provided by the present invention; Figure 13 This is a schematic diagram of the cross-sectional structure of the photovoltaic roadbed system provided by the present invention. Figures 12 to 13 The photovoltaic roadbed system includes: at least one photovoltaic power generation system 1000 of any of the above types, a central dividing strip 2000, a pair of central guardrails 3000, a pair of roadside guardrails 4000, and a roadbed 5000; the photovoltaic anti-glare panel assembly 100 in the photovoltaic power generation system 1000 is arranged on the central dividing strip 2000, and the pair of central guardrails 3000 are arranged on both sides of the central dividing strip 2000; and the pair of roadside guardrails 4000 are arranged on both side edges of the roadbed 5000.

[0127] The photovoltaic anti-glare panel 110 can be positioned parallel to the roadway and / or perpendicular to it. The central guardrail 3000 is positioned on the median 2000 of the roadbed 5000, on either side of the photovoltaic anti-glare panel assembly 100. The photovoltaic anti-glare panel 110 is positioned 15-25 cm from the corrugated guardrail of the median 2000.

[0128] Specifically, the central guardrail 3000 consists of two to three corrugated steel guardrail panels and fixed columns 133. The central guardrail 3000 ensures the safety of the photovoltaic anti-glare panel assembly 100, preventing damage from vehicle collisions or traffic accidents. The roadside corrugated guardrails are located on the shoulder of the roadbed 5000, corresponding to the central guardrail 300019, to protect vehicles. The central guardrail 3000 and the roadside corrugated guardrails are 0.75-1.0m high.

[0129] Furthermore, the photovoltaic roadbed 5000 system provided in this embodiment is based on a photovoltaic pavement, the surface of which is made of a light-transmitting, high-strength glass material with load-bearing capacity, and has built-in single-sided photovoltaic panels that can convert solar radiation received by the pavement into electricity.

[0130] The advantages of the photovoltaic roadbed 5000 system provided in this embodiment are mainly reflected in:

[0131] (1) The photovoltaic roadbed 5000 system fully combines photovoltaic power generation with the roadbed 5000 structure, which not only meets the functional requirements of the highway roadbed 5000 anti-glare net, but also provides green electricity, which helps the highway roadbed 5000 develop in the direction of electrification, serves the development of electric vehicles, and implements the "photovoltaic + transportation" macro strategy.

[0132] (2) my country has a vast territory and a very large road network, especially a highway network. The new photovoltaic roadbed 5000 system has broad application prospects and will be able to contribute to the realization of the carbon peak and carbon neutrality goals.

[0133] In one embodiment of the present invention, slopes 5100 are provided on both sides of a roadbed 5000, and photovoltaic anti-glare panel assemblies 100 are installed on the slopes 5100. The photovoltaic anti-glare panel assemblies 100 are fixed to the slopes 5100 at a certain inclination angle according to the slope of the slopes 5100, thereby achieving photovoltaic power generation.

[0134] The present invention provides a photovoltaic anti-glare panel assembly 100, comprising a photovoltaic anti-glare panel 110, an aluminum alloy frame 120, a base 131, a junction box, wires, supports, and columns 133. Suitable for use in the central median 2000 and central movable guardrails of a highway roadbed 5000, it can reduce the glare of oncoming vehicle lights while fully utilizing solar energy for photovoltaic power generation and providing green electricity. The electricity can be used for independent use such as energy storage, batteries, and charging piles, or it can be connected to the power grid for grid-connected transmission. The present invention also provides a photovoltaic power generation system 1000, comprising a photovoltaic anti-glare panel assembly 100, a DC busbar, a DC power distribution device, an inverter, an AC power distribution device, and a user terminal.
