Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic technology, specifically relating to rooftop photovoltaic power stations. Background Technology

[0002] Currently, the pitched roof hook solution has become the mainstream in the rooftop photovoltaic (PV) power station market due to its good installation effect, aesthetics, practicality, and positive market feedback. Given the diverse range of housing types available, adapting the pitched roof hook solution to various housing layouts has become a key research focus for major companies to meet market demands.

[0003] The hook-based solution for sloping roofs is suitable for tile roofs made of ceramic tiles, cement tiles, brick tiles, etc., which have a certain strength and the load-bearing capacity for roof construction. However, research revealed that many rural houses have two or three rows of tiles at the ridge that are cemented and fixed to the roof surface for waterproofing, making them impossible to remove. If they cannot be removed, the tiles need to be broken, which requires high-quality construction. In this case, forcibly removing the tiles and placing hooks underneath them could lead to improper construction operations and poor waterproofing, resulting in a high risk of leakage. This would affect the waterproofing effect of the subsequent power station support, causing more customer complaints, maintenance difficulties, and impacting the daily lives of farmers and the company's brand influence. If the entire photovoltaic array is moved downwards to avoid the ridge, the installation capacity will be greatly reduced, and a large area of ​​the roof surface at the ridge will be exposed, affecting the aesthetics of the entire solution. On the other hand, research also found that some house types have uneven slopes with irregular drops, and the roof tiles are small black tiles. In these cases, a purely elevated solution would easily crush the tiles, severely affecting the roof's waterproofing. Utility Model Content

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a photovoltaic installation structure and photovoltaic power station for sloping roofs that combines hooks and overhead structures, thereby solving the problem that photovoltaic power stations cannot be installed on some special house types using a pure hook solution.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] First, a photovoltaic installation structure for sloping roofs combining hooks and overhead structures is provided, including an array of hook components installed on the sloping roof, at least one row of overhead short support components, and a row of inclined beams. At least one row of overhead short support components is installed on the upper longitudinal side of the sloping roof near the ridge, and the array of hook components is installed on the lower longitudinal side of the sloping roof. The inclined beams are connected to the hook components and overhead short support components below them, and crossbeams are vertically fixed on the inclined beams, with photovoltaic modules installed on the crossbeams.

[0007] Preferably, the inclined beam adopts a double inclined beam structure, which includes a lower inclined beam, an upper inclined beam parallel to the lower inclined beam, and a number of short columns between the lower and upper inclined beams. The lower inclined beam is located above the lower longitudinal side of the sloping roof and is connected to the hook assembly. The upper longitudinal end of the upper inclined beam extends to the ridge. The crossbeam is fixed to the upper inclined beam.

[0008] Preferably, the double-sloping beam structure has two rows of short columns on both sides of the transverse direction. The upper end of the short columns is fixed to the side of the upper inclined beam with bolts, and the lower end of the short columns is fixed to the side of the lower inclined beam with bolts.

[0009] Preferably, the overhead short support assembly includes a short support member on the tile supported on the tile, a diagonal beam connector fixed to the side of the diagonal beam, and a support column connecting the short support member on the tile and the diagonal beam connector.

[0010] Preferably, the short support member on the tile and the support column are made of U-steel, the inclined beam connector is made of angle steel, the bottom of the support column is fixed to the upper longitudinal side of the short support member on the tile with bolts, the top of the support column is fixed to the side of the inclined beam with bolts, one side of the angle steel is fixed to the side of the inclined beam with bolts, and the other side is fixed to the lower upper longitudinal side of the support column with bolts.

[0011] Preferably, the overhead short support assembly includes a short support member on the tile supporting the tile and support bolts connecting the short support member on the tile and the inclined beam.

[0012] Preferably, the hook assembly includes a hook base, a first hook, and a second hook. The hook base is fixed to the sloping roof, the second hook is fixed to the bottom of the sloping beam, and the first hook connects the hook base and the second hook.

[0013] Preferably, the hook base is fixed to the sloping roof using a clamp or expansion bolts.

[0014] Preferably, the spacing between two adjacent inclined beams, two adjacent hook components, and two adjacent overhead short support components in the horizontal direction is equal; and / or, photovoltaic modules are provided on both sides of the ridge of the roof, and the upper ends of the inclined beams on both sides of the roof are fixed together by inclined beam connecting bolts.

[0015] In addition, a photovoltaic power station is also provided, including the aforementioned sloping roof photovoltaic installation structure.

[0016] In addition, a rooftop photovoltaic power station is also provided, including the aforementioned sloping roof photovoltaic installation structure.

[0017] The present invention adopts the above technical solution and has the following beneficial effects:

[0018] 1. The technical solution of this utility model combines a hook structure and an overhead structure. The overhead short support assembly is installed on the upper longitudinal side of the sloping roof near the ridge, while the hook assembly array is installed on the lower longitudinal side of the sloping roof. Compared with the existing pure hook solution, the row of hooks near the ridge is replaced by the overhead short support assembly. Since the overhead short support assembly can be directly installed on the tiles without removing them, it not only reduces on-site installation steps, avoids rework and wasted manpower, and improves construction efficiency, but also avoids the risk of leakage caused by forcibly removing the tiles. Furthermore, since the weight is mainly borne by the hook assembly array, the overhead short support assembly bears a smaller load, preventing the tiles from being crushed and affecting the roof's waterproofing.

[0019] Therefore, compared with the existing pure hook-and-mount schemes and pure overhead schemes on the market, the integrated hook-and-mount photovoltaic installation structure greatly improves the installed capacity and aesthetics of roofless photovoltaic power stations, and ensures the profitability of the power station.

[0020] 2. The sloping roof is uneven, and the height near the ridge is relatively high, making pure hook-and-loop or pure overhead solutions unsuitable. The proposed solution utilizes a double-sloping beam structure. This double-sloping beam structure raises the overall height, compensating for the roof's height difference. Combined with the overhead short support components near the ridge, it forms a unified installation structure, resolving the issues of uneven sloping roofs, high height near the ridge, and the inability to develop irregularly shaped houses.

[0021] 3. The double-sloping beam structure has two rows of short columns on both sides. The upper ends of the short columns are bolted to the side of the upper inclined beam, and the lower ends of the short columns are bolted to the side of the lower inclined beam. Using short columns on both sides to support the upper inclined beam not only ensures structural stability but also facilitates assembly and fixing by laterally fixing the short columns to the upper and lower inclined beams.

[0022] 4. The aforementioned overhead short support assembly includes a short support component on the tile, a diagonal beam connector fixed to the side of the diagonal beam, and a support column connecting the short support component and the diagonal beam connector. The short support component and the support column are made of U-steel or C-steel, the diagonal beam connector is made of angle steel, the bottom of the support column is bolted to the upper longitudinal side of the short support component, the top of the support column is bolted to the side of the diagonal beam, one side of the angle steel is bolted to the side of the diagonal beam, and the other side is bolted to the lower upper longitudinal side of the support column. Since both the angle steel and the support column are bolted to the side of the diagonal beam, assembly and fixing are convenient.

[0023] 5. The aforementioned overhead short support assembly includes a short support member on the tile and support bolts connecting the short support member and the inclined beam. The support bolts pass through the short support member and the inclined beam from bottom to top. Nuts are connected above the short support member, and nuts are connected on both the upper and lower sides of the inclined beam. The fixing height of the support bolts to the inclined beam can be adjusted by adjusting the nuts, which facilitates assembly and fixing.

[0024] 6. The hook assembly includes a hook base, a first hook, and a second hook. When installing the hook assembly, the hook base is installed on the sloping roof using clamps or expansion bolts. The first hook and the second hook are fixed together with bolts, and the first hook is fixed together with the hook base. Therefore, the hook assembly can lift the photovoltaic module, maintain a reasonable gap between the photovoltaic module and the roof, and avoid crushing the tiles.

[0025] 7. When photovoltaic modules and photovoltaic installation structures are installed on both sides of the sloping roof, the upper ends of the upper sloping beams on both sides of the sloping roof are fixed together by sloping beam connecting bolts, thereby fixing the photovoltaic installation structures on both sides into one unit and improving the overall integrity and structural stability.

[0037] Those skilled in the art will understand that, without conflict, the features in the following embodiments and implementations can be combined with each other.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0042] The sloping roof photovoltaic installation structure of this embodiment can cover rural houses with roof tiles that cannot be removed, houses with small black tiles, etc.

[0043] Referring to existing technology, current sloping roof photovoltaic installation structures include a row of diagonal beams horizontally arranged on the sloping roof, with crossbeams vertically fixed to these beams. Photovoltaic modules are installed on the crossbeams, and hook assemblies are provided between the diagonal beams and the sloping roof. However, in cases where two or three rows of tiles near the ridge cannot be removed, or where the sloping roof is irregularly shaped and the area near the ridge is relatively high, the hook assemblies cannot be installed near the ridge. To solve these problems, [further details are needed]. Figures 1 to 7 As shown, a sloping roof photovoltaic installation structure combining hooks and overhead structures is provided, including a hook assembly array installed on the sloping roof 51 of a building 5, at least one row of overhead short support assemblies 2, and a row of inclined beams. The at least one row of overhead short support assemblies 2 is installed on the upper longitudinal side of the sloping roof near the ridge, and the hook assembly array is installed on the lower longitudinal side of the sloping roof. The inclined beams are connected to the hook assemblies and overhead short support assemblies below, and crossbeams 4 are vertically and crosswise fixed on the inclined beams. Photovoltaic modules 400 are installed on the crossbeams 4.

[0044] It is understandable that the spacing between two adjacent inclined beams, two adjacent hook assemblies, and two adjacent overhead short support assemblies is equal in the horizontal direction, so that the inclined beams can be connected to the hook assemblies and overhead short support assemblies below.

[0045] This implementation combines hooks and overhead installation. The overhead short support components are installed on the upper longitudinal side of the sloping roof near the ridge, while the hook array is installed on the lower longitudinal side of the sloping roof. Compared to existing pure hook solutions, the row of hooks near the ridge is replaced with overhead short support components. Since the overhead short support components can be directly installed on the tiles without removing them, this not only reduces on-site installation steps, avoids rework and wasted manpower, and improves construction efficiency, but also avoids the risk of leakage caused by forcibly removing tiles. Furthermore, the weight is mainly borne by the hook array, while the overhead short support components bear a smaller load, preventing the tiles from being crushed and affecting the roof's waterproofing. Therefore, compared to existing pure hook and pure overhead solutions on the market, the integrated hook and overhead photovoltaic installation structure significantly increases the installed capacity and aesthetics of roofless photovoltaic power stations, ensuring the profitability of the power station.

[0046] In some implementations, the sloping roof is uneven and the height near the ridge is relatively high, making pure hook-and-loop or pure stilt-and-loop solutions unsuitable. For example... Figure 2 As shown, the inclined beam adopts a double inclined beam structure 3. The double inclined beam structure 3 includes a lower inclined beam 31, an upper inclined beam 32 parallel to the lower inclined beam, and several short columns 33 between the lower and upper inclined beams. The lower inclined beam 31 is located above the lower longitudinal side of the sloping roof and is connected to the hook assembly 1. The lower inclined beam 31 is relatively short, its length only covering the upper longitudinal side of the sloping roof. The upper inclined beam 32 is relatively long, its upper longitudinal end extending above the ridge 52. The crossbeam 4 is fixed to the upper inclined beam 32. The double inclined beam structure can raise the overall height, compensate for the roof drop, and thus cooperate with the suspended short support assembly near the ridge to form an integrated installation structure, solving the problems of uneven sloping roofs, high height near the ridge, and the inability to develop irregularly shaped houses.

[0047] like Figure 2 As shown, the double-sloping beam structure 3 has two rows of short columns 33 on both sides of its transverse direction. The upper ends of the short columns are bolted to the side of the upper inclined beam, and the lower ends of the short columns are bolted to the side of the lower inclined beam. By using short columns on both sides to support the upper inclined beam, the structure is not only stable, but the short columns are also fixed to the upper and lower inclined beams from the side, which facilitates assembly and fixing.

[0048] Combining existing technologies Figure 3As shown, the photovoltaic module 400 is fixed to the crossbeam using a pressure block assembly 42, and the crossbeam is fixed to the upper inclined beam using fixing bolts 41. The crossbeam is made of C-steel, with limiting flanges on both sides of its opening. The pressure block assembly includes an upper pressure block, a lower pressure block, and pressure block bolts connecting the upper and lower pressure blocks. The lower pressure block is U-shaped and installed inside the crossbeam, limited by the limiting flanges. The top of the upper pressure block has pressing flanges on opposite sides or one side (pressing flanges on both sides of the middle pressure block, and on one side of the side pressure block), which press against the photovoltaic module frame. The top of the lower pressure block has threaded holes, and the pressure block bolts can be hexagonal socket head cap screws, which pass through the fixing holes on the upper pressure block from top to bottom and connect to the threaded holes on the lower pressure block. When tightening the pressure block bolts, the lower pressure block is lifted, and the tightening stops when the two sides of the U-shaped lower pressure block are engaged with the limiting flanges.

[0049] In this embodiment, photovoltaic modules 400 are installed on the sloping roof surfaces 51 on both sides of the roof ridge. For example... Figure 4 As shown, the upper ends of the inclined beams on both sides of the sloping roof are fixed together by inclined beam connecting bolts 34. This fixes the photovoltaic installation structures on both sides into a whole, improving the overall integrity and structural stability.

[0050] like Figure 5 As shown, in some embodiments, the overhead short support assembly 2 includes a short support member 21 supported on the tile, a diagonal beam connector 23 fixed to the side of the diagonal beam, and a support column 22 connecting the short support member and the diagonal beam connector. Specifically, a waterproof layer 25 is provided between the bottom surface of the short support member 21 and the tile. The short support member 21 and the support column 22 are made of U-steel or C-steel, the diagonal beam connector 23 is made of angle steel, the bottom of the support column is bolted to the upper longitudinal side of the short support member, the top of the support column is bolted to the side of the diagonal beam, one side of the angle steel is bolted to the side of the diagonal beam, and the other side is bolted to the lower upper longitudinal side of the support column. Since both the angle steel and the support column are bolted to the side of the diagonal beam, assembly and fixing are convenient.

[0051] like Figure 6 As shown, in some embodiments, the overhead short support assembly 2 includes a short support member 21 supported on the tile and a support bolt 24 connecting the short support member and the inclined beam. Specifically, the short support member 21 is made of U-steel or C-steel, with its opening facing downwards and supporting the tile. The support bolt 24 passes through the short support member 21 and the upper inclined beam 32 from bottom to top. Nuts are connected to the upper side of the short support member 21, and nuts are connected to both the upper and lower sides of the upper inclined beam 32. The fixing height of the support bolt to the upper inclined beam can be adjusted by adjusting the nuts, facilitating assembly and fixing.

[0052] Alternatively, one can refer to the conventional structure of hook components in existing technologies and combine it with... Figure 2 As shown, the hook assembly 1 includes a hook base 11, a first hook 12, and a second hook 13. The hook base 11 is fixed to the sloping roof, and the second hook 13 is fixed to the bottom of the sloping beam. The first hook 12 connects the hook base and the second hook. The hook base 11 has an L-shaped structure, including a vertically connected base plate and a side plate. The base plate is fixed to the sloping roof using clamps or expansion bolts, and has mounting holes. When installing the hook base 11, it is fixed through the mounting holes using clamps or expansion bolts. Specifically, the first hook has a Z-shaped structure, including a first fixed side, a second fixed side, and a connecting side connecting the first and second fixed sides. The second hook has an L-shaped structure, including a vertically connected support portion and a connecting portion. The first fixed side and the side plate are overlapped and fixed with bolts, and the connecting portion is overlapped and fixed with the second fixed side using bolts. Furthermore, anti-slip textures can be provided between the first fixed side and the side plate, as well as between the connecting portion and the second fixed side. The side plate has a row of vertical holes, and the vertical holes have grooves on opposite side walls. The first fixed edge has threaded holes, which are connected to vertical holes with bolts. The installation height of the hook assembly can be adjusted through the vertical holes, and it is positioned by toothed grooves of different heights. Here, there can be three vertical holes in a row, and the installation position of the hook assembly can be adjusted by installing it into different vertical holes. During installation, the anti-slip texture of the side plate cooperates with the anti-slip texture of the first fixed edge to prevent the hook assembly from sliding downwards and to prevent the hook assembly from rotating relative to the hook base when it is fastened. Similarly, the second fixed edge and the joint also adopt a bolt fixing and anti-slip texture cooperation structure to fix it and prevent mutual rotation.

Those skilled in the art should understand that the utility model includes, but is not limited to, the content described in the accompanying drawings and the specific embodiments above.
