[0043] According to the data released by the National Energy Administration, as of the end of 2024, the cumulative installed capacity of distributed photovoltaic power generation reached 370 million kilowatts, which is 121 times that at the end of 2013 and accounts for 42% of the total installed capacity of photovoltaic power generation. In terms of new installed capacity, the new installed capacity of distributed photovoltaic power generation reached 120 million kilowatts in 2024, accounting for 43% of the new installed capacity of photovoltaic power generation in that year. Distributed photovoltaic power generation has become an important force in energy transformation.

[0044] With the rapid development of distributed photovoltaics, there have been multiple safety and quality accidents in the industry. Among them, the photovoltaic modules of multiple projects have been overturned by strong winds, causing significant losses to investors.

[0045] Through research by the inventor, it is found that the high-quality buildings that can currently install rooftop photovoltaics have basically been constructed, and the available resources for development are becoming fewer and fewer. The buildings without rooftop photovoltaics have been built for a long time and have poor load-bearing capacity. If photovoltaic panels are installed according to the traditional plan, on the one hand, it cannot meet the roofing load requirements, and on the other hand, its wind resistance is also insufficient.

[0046] The present invention proposes a wind-proof photovoltaic bracket to improve the wind resistance of photovoltaic modules.

[0047] Please refer to Figures 1 to 3, in an embodiment of the present invention, the anti-wind photovoltaic bracket 100 is used to be installed on the roof surface 200. The edge of the roof surface 200 includes a first side 230 and a second side 240 arranged adjacent to each other. The anti-wind photovoltaic bracket 100 includes a bracket assembly 1 and a sealing plate 2. The bracket assembly 1 includes longitudinal beams 11, purlins 12 and waterproof strips 13. The numbers of the longitudinal beams 11, purlins 12 and waterproof strips 13 are all multiple. Each longitudinal beam 11 is connected to the roof surface 200, and the extending direction of each longitudinal beam 11 is parallel to the extending direction of the first side 230. The multiple longitudinal beams 11 are arranged at intervals in sequence along the extending direction of the second side 240; each purlin 12 is arranged above the longitudinal beam 11, and the extending direction of each purlin 12 is parallel to the extending direction of the second side 240; the multiple purlins 12 are arranged at intervals in sequence along the extending direction of the first side 230, and the purlin 12 is perpendicularly arranged to the longitudinal beam 11; each waterproof strip 13 is arranged above the purlin 12, and the extending direction of each waterproof strip 13 is parallel to the extending direction of the longitudinal beam 11. The multiple waterproof strips 13 are arranged at intervals in sequence along the extending direction of the second side 240. Photovoltaic panels 300 are arranged above any two adjacent waterproof strips 13; the number of counterweights 3 is multiple. At least one longitudinal beam 11 of any two adjacent longitudinal beams 11 is provided with a counterweight 3; the sealing plate 2 surrounds the periphery of the roof surface 200, and the sealing plate 2 is also hermetically connected to the photovoltaic panel 300 located at the edge of the roof surface 200, so that the sealing plate 2 can seal the gap between the photovoltaic panel 300 located at the edge of the roof surface 200 and the roof surface 200.

[0048] The technical solution of the present invention directly connects the longitudinal beam 11 to the roof surface 200, thus eliminating the installation of the upright column used to connect the longitudinal beam 11 and the roof in the traditional installation. On the one hand, it reduces the requirement for the installation load, so as to be able to adapt to the installation of buildings with a long service life; on the other hand, it reduces the distance between the photovoltaic panel 300 and the roof surface 200, thereby reducing the probability of air flow entering between the photovoltaic panel 300 and the roof surface 200. Then, by arranging the sealing plate 2 around the outer edge of the roof surface 200, and the side of the sealing plate 2 facing the roof surface 200 is also hermetically connected to the photovoltaic panel 300 located at the edge of the roof surface 200, the gap between the photovoltaic panel 300 located at the edge of the roof surface 200 and the roof surface 200 is sealed, preventing air flow from entering between the roof surface 200 and the photovoltaic panel 300 from this gap, thereby effectively reducing the probability of the photovoltaic panel 300 being lifted by the wind, and further effectively improving the wind resistance of the photovoltaic panel 300.

[0049] It should be noted that the sealing plate 2 can be a whole flexible plate or composed of multiple plates connected in sequence, without limitation here; among them, the longitudinal beam 11 and the roof can be connected by bolts or nailed to the roof, without limitation here, and the connection between the longitudinal beam 11 and the purlin 12 can be by bolt connection or welding, without limitation here; the connection between the waterproof strip 13 and the purlin 12 can be by bolt connection or welding, without limitation here, and the connection between the waterproof strip 13 and the photovoltaic panel 300 can be that the waterproof strip 13 clamps the photovoltaic panel 300 or the photovoltaic panel 300 is adhered to the waterproof strip 13. It should also be noted that the roof surface 200 can be a flat surface or an inclined surface, without limitation here. More importantly, the sealing plate 2 can be made of a stainless steel plate with a thickness of 0.6 mm.

[0050] Please refer to Figure 1 、 Figure 2 and Figure 4 , in an embodiment, the anti-wind photovoltaic bracket 100 further includes a counterweight 3, and at least one of any two adjacent longitudinal beams 11 is provided with a counterweight 3. By arranging the counterweight 3 on the longitudinal beam 11, the longitudinal beam 11 is not easily separated from the roof surface 200, thereby effectively improving the wind resistance of the photovoltaic panel 300.

[0051] Please refer to Figure 1 and Figure 2 , in an embodiment, the anti-wind photovoltaic bracket 100 further includes positioning bolts 4. The number of positioning bolts 4 is multiple. The multiple longitudinal beams 11 are divided into first longitudinal beams 111 and second longitudinal beams 112 arranged alternately in sequence. The counterweight 3 is arranged on the first longitudinal beams 111, and each first longitudinal beam 111 abuts against the roof surface 200; each second longitudinal beam 112 is connected to the roof surface 200 through a positioning bolt 4. In this embodiment, by pressing the counterweight 3 on the first longitudinal beam 111, the first longitudinal beam 111 is not easily separated from the roof surface 200; then, by passing the positioning bolt 4 through the through hole on the second longitudinal beam 112 and driving it into the roof surface 200, the second longitudinal beam 112 is not easily separated from the roof surface 200; on the one hand, both the first longitudinal beam 111 and the second longitudinal beam 112 are not easily separated from the roof surface 200, ensuring the wind resistance of the photovoltaic panel 300; on the other hand, since not every longitudinal beam 11 relies on arranging a counterweight 3 to ensure that it is not easily separated from the roof surface 200, but by combining the additional counterweight 3 and the positioning bolts 4, and the mass of the positioning bolts 4 is much lower than that of the counterweight 3, the installation load requirement of the anti-wind photovoltaic bracket 100 on the roof surface 200 is effectively reduced.

[0052] Please refer to Figure 1, in one embodiment, a plurality of counterweight blocks 3 are provided on each first longitudinal beam 111, and the plurality of counterweight blocks 3 are arranged at intervals in the extending direction of the first longitudinal beam 111; taking one of the first longitudinal beams 111 as an example, a plurality of counterweight blocks 3 are provided on this first longitudinal beam 111, and the plurality of counterweight blocks 3 are arranged at intervals in the extending direction of this first longitudinal beam 111, thereby effectively improving the connection reliability between the first longitudinal beam 111 and the roof surface 200 and enhancing the wind resistance of the photovoltaic panel 300.

[0053] In one embodiment, a plurality of positioning bolts 4 are provided on each second longitudinal beam 112, and the plurality of positioning bolts 4 are arranged at intervals in the extending direction of the second longitudinal beam 112. Taking one of the second longitudinal beams 112 as an example, this second longitudinal beam 112 is connected by a plurality of positioning bolts 4, and the plurality of positioning bolts 4 are arranged at intervals in the extending direction of the second longitudinal beam 112, thereby effectively increasing the connection strength between the second longitudinal beam 112 and the roof surface 200 and enhancing the wind resistance of the photovoltaic panel 300.

[0054] Please refer to Figure 2 , Figure 4 and Figure 5 , in one embodiment, a receiving groove 31 capable of receiving the longitudinal beam 11 is provided at the bottom of each counterweight block 3. By providing the receiving groove 31 for receiving the longitudinal beam 11 on the counterweight block 3, it is convenient for the installation and positioning of the counterweight block 3.

[0055] Please refer to Figure 1, in an embodiment, the roof surface 200 includes a first slope surface 210 and a second slope surface 220. The first side 230 includes a first hypotenuse 231 and a second hypotenuse 232 that are connected to each other. The edge of the first slope surface 210 is provided with the first hypotenuse 231, and the edge of the second slope surface 220 is provided with the second hypotenuse 232. The plurality of longitudinal beams 11 are divided into a plurality of first beams 113 and a plurality of second beams 114. Each first beam 113 is connected to the first slope surface 210, and the extending direction of each first beam 113 is parallel to the extending direction of the first hypotenuse 231; each second beam 114 is connected to the second slope surface 220, and the extending direction of each second beam 114 is parallel to the extending direction of the second hypotenuse 232. The first beam 113 extends along the inclined direction of the first slope surface 210, so that the first beam 113 can be attached to the first slope surface 210, thereby reducing the distance between the photovoltaic panel 300 and the first slope surface 210; similarly, the second beam 114 extends along the inclined direction of the second slope surface 220, so that the second beam 114 can be attached to the second slope surface 220, thereby reducing the distance between the photovoltaic panel 300 and the first slope surface 210; the wind resistance of the photovoltaic panel 300 is improved, and the installation on the sloping roof can be taken into account while ensuring wind resistance. It should be noted that the first beam 113 includes a first longitudinal beam 111 and a second longitudinal beam 112 that are alternately arranged in sequence, and the second beam 114 includes a first longitudinal beam 111 and a second longitudinal beam 112 that are alternately arranged in sequence.

[0056] In an embodiment, the two ends of the first beam 113 are respectively connected to the ridge and the eaves of the roof surface 200; and / or, the two ends of the second beam 114 are respectively connected to the ridge and the eaves of the roof surface 200. The two ends of the first beam 113 are respectively connected to the ridge and the eaves, increasing the connection strength between the first beam 113 and the roof surface 200 and improving the wind resistance of the photovoltaic panel 300; similarly, the two ends of the second beam 114 are respectively connected to the ridge and the eaves, increasing the connection strength between the second beam 114 and the roof surface 200 and improving the wind resistance of the photovoltaic panel 300.

[0057] In an embodiment, the gap between the photovoltaic panel 300 and the roof surface 200 is not greater than 10 cm. By controlling the gap between the photovoltaic panel 300 and the roof surface 200 to be not greater than 10 cm, the probability of air flow entering between the photovoltaic panel 300 and the roof surface 200 is effectively reduced. It should be noted that the distance between the photovoltaic panel 300 and the roof surface 200 is not greater than 10 cm on the premise of ensuring that there is a corresponding installation space for the waterproof strip 13, the purlin 12, the counterweight 3, and the longitudinal beam 11. It should be noted that the size of the gap between the photovoltaic panel 300 and the roof surface 200 is as Figure 3 the d in, that is, d is not greater than 10 cm.

[0058] Please refer to Figure 6 ,Figure 6 The flowchart of the first embodiment of the construction method of the anti-wind and anti-light photovoltaic support provided by the present invention is shown. The present invention also proposes a construction method of the anti-wind and anti-light photovoltaic support. The construction method of the anti-wind and anti-light photovoltaic support is applied to the above-mentioned anti-wind and anti-light photovoltaic support.

[0063] S300, installing a plurality of waterproof strips on the upper side of the purlins at intervals in sequence along the extension direction of the second side;

[0064] By arranging a plurality of waterproof strips above the purlins, the waterproof performance of the anti-wind and anti-light photovoltaic support is improved. The waterproof strips can be connected to the purlins through bolts, or can be directly connected to the purlins by welding.

[0065] S400, installing photovoltaic panels above the waterproof strips;

[0066] Photovoltaic panels are arranged between any two adjacent waterproof strips. There is a gap between any two photovoltaic panels. The waterproof strip is provided with a waterproof groove corresponding to the gap, thereby improving the waterproof performance of the anti-wind and anti-light photovoltaic support.

[0067] S500, arranging a sealing plate around the periphery of the roof surface and the photovoltaic panels; so that the sealing plate can seal the gap between the photovoltaic panels at the edge of the roof surface and the roof surface.

[0068] By arranging the sealing plate around the outer edge of the roof surface, and the sealing plate is also hermetically connected to the photovoltaic panels at the edge of the roof surface, the gap between the photovoltaic panels at the edge of the roof surface and the roof surface is sealed, preventing air flow from entering between the roof surface and the photovoltaic panels from this gap, thereby effectively reducing the probability of the photovoltaic panels being lifted by the wind, and further effectively improving the wind resistance of the photovoltaic panels.

[0069] Among them, the longitudinal beam is directly connected to the roof surface, thus eliminating the installation of columns used to connect the longitudinal beam and the roof in traditional installations. On the one hand, the requirement for installation load is reduced, enabling the installation on buildings with a long service life; on the other hand, the distance between the photovoltaic panel and the roof surface is reduced, thereby reducing the probability of air flow entering between the photovoltaic panel and the roof surface. Additionally, a sealing plate is arranged around the outer edge of the roof surface, and the side of the sealing plate facing the roof surface is also hermetically connected to the photovoltaic panel located at the edge of the roof surface, thus sealing the gap between the photovoltaic panel at the edge of the roof surface and the roof surface, preventing air flow from entering between the roof surface and the photovoltaic panel through this gap, effectively reducing the probability of the photovoltaic panel being lifted by the wind, and thus effectively improving the wind resistance of the photovoltaic panel.

[0072] S120, installing the counterweight blocks on each of the first longitudinal beams, and simultaneously connecting each of the second longitudinal beams to the roof surface through the positioning bolts.

[0073] Among them, by pressing the counterweight blocks on the first longitudinal beams, the first longitudinal beams are not easily separated from the roof; then, by passing the positioning bolts through the through holes on the second longitudinal beams and driving them into the roof surface, the second longitudinal beams are not easily separated from the roof; on the one hand, both the first longitudinal beams and the second longitudinal beams are not easily separated from the roof surface, ensuring the wind resistance of the photovoltaic panel; on the other hand, since not every longitudinal beam relies on setting counterweight blocks to ensure its non-separation from the roof surface, but by combining the addition of counterweight blocks and positioning bolts, the mass of the positioning bolts is much lower than that of the counterweight blocks, thus effectively reducing the installation load requirement of the anti-wind photovoltaic support on the roof surface.
