Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, and in particular to photovoltaic support structures. Background Technology

[0002] Solar photovoltaic (PV) power generation primarily relies on solar panels to absorb solar energy, thus requiring the installation of PV modules outdoors, such as on rooftops or other locations with ample sunlight. Currently, when installing PV modules on tiled roofs, PV hooks are required. To install these hooks, the roof tiles are first removed, and the base of the PV hook is secured to the roof purlins using screws or welding. Then, the tiles are replaced, with the hook's components partially protruding from the gaps between the tiles. However, due to the varying installation positions of the purlins on tiled roofs, existing PV hooks suffer from limitations in adaptability, as some tiles may be too long to protrude from the purlins. Utility Model Content

[0003] Therefore, it is necessary to provide a photovoltaic support structure to address the technical problem of existing photovoltaic hooks having low adaptability due to the inability to expose the tiles because the tiles are too long.

[0031] See Figure 1 , Figure 1 A schematic diagram of a photovoltaic support structure provided in an embodiment of this utility model. Figure 1 This utility model provides a photovoltaic support structure, including a base 100, a hook 200, and a guide rail 300. The base 100 is used to connect to a sloping roof. The hook 200 includes a first adjusting arm 210, a second adjusting arm 220, and a first fastener 230. The first adjusting arm 210 is connected to the base 100, and the second adjusting arm 220 is connected to the end of the first adjusting arm 210 away from the base 100. The second adjusting arm 220 is movable relative to the first adjusting arm 210 in a first direction. The first fastener 230 is connected to the first adjusting arm 210 and the second adjusting arm 220 to fix the position of the second adjusting arm 220 relative to the first adjusting arm 220 in the first direction, wherein the first direction is the direction in which the hook extends relative to the roof tile. The guide rail 300 is installed at the end of the second adjusting arm 220 away from the first adjusting arm 210 and is used to support the photovoltaic module.

[0032] Specifically, in this application, the second adjusting arm 220 can move relative to the first adjusting arm 210 in the direction in which the hook extends relative to the tile, thereby adjusting the size of the hook 200 in the direction in which the hook extends relative to the tile. This ensures that part of the hook 200 can extend from the gap between adjacent tiles to accommodate tiles of different sizes, thereby improving the adaptability of the photovoltaic support structure.

[0033] It should be noted that the instruction manual is attached. Figure 1Taking XX' as an example, we define XX' as the first direction, YY' as the second direction, and ZZ' as the third direction. The first, second, and third directions are all perpendicular to each other. The following descriptions will all use the first, second, and third directions.

[0034] See Figure 1 In one embodiment, at least one of the first adjusting arm 210 and the second adjusting arm 220 has a first adjusting hole 240 extending in a first direction, and a first fastener 230 passes through the first adjusting hole 240.

[0035] Specifically, the first fastener 230 passes through the first adjustment hole 240 and is slidably connected to the hole wall of the first adjustment hole 240 along the first direction, which can guide the second adjustment arm 220 to move relative to the first adjustment arm 210 along the first direction, thereby accurately adjusting the length of the hook in the first direction.

[0036] Furthermore, both the first adjusting arm 210 and the second adjusting arm 220 are provided with first adjusting holes 240, and the first fastener 230 passes through the first fastening holes on the first adjusting arm 210 and the second adjusting arm 220 and is connected to the first adjusting arm 210 and the second adjusting arm 220. By providing first adjusting holes 240 on both the first adjusting arm 210 and the second adjusting arm 220, the first fastener 230 can be easily disassembled, thus facilitating its replacement when damaged, and improving the service life of the photovoltaic support structure. Preferably, the first fastener 230 is a bolt.

[0037] See Figure 1 , Figure 2 , Figure 3 and Figure 4 , Figure 2 A schematic diagram of a photovoltaic support structure provided in an embodiment of this utility model. Figure 2 . Figure 3 This is a schematic diagram of the first adjusting arm in a photovoltaic support structure provided in an embodiment of the present invention. Figure 4 This is a schematic diagram of the second adjusting arm cooperating with the guide rail in a photovoltaic support structure provided by an embodiment of the present invention. In one embodiment, the first adjusting arm 210 includes a first connecting section 211 and a first overlapping section 212 connected to each other, and the second adjusting arm 220 includes a second connecting section 221 and a second overlapping section 222 connected to each other. A first adjusting hole 240 is disposed on at least one of the first overlapping section 212 and the second overlapping section 222. The first overlapping section 212 and the second overlapping section 222 overlap. In the thickness direction of the tile, the side of the first overlapping section 212 near the second overlapping section 222 is recessed relative to the first connecting section 211, and the side of the second overlapping section 222 near the first overlapping section 212 is recessed relative to the second connecting section 221.

[0038] Specifically, both the first overlapping section 212 and the second overlapping section 222 are provided with first adjustment holes 240, and first fasteners 230 pass through the first adjustment holes 240. By moving the second adjustment arm 220 relative to the first adjustment arm 210 in a first direction, the second overlapping section 222 slides relative to the first overlapping section 212. Since, in the thickness direction of the tile, the side of the first overlapping section 212 near the second overlapping section 222 is recessed relative to the first connecting section 211, and the side of the second overlapping section 222 near the first overlapping section 212 is recessed relative to the second connecting section 221, the height of the overlap between the first overlapping section 212 and the second overlapping section 222 can be reduced when they overlap, thereby reducing interference with the tile and improving the adaptability of the photovoltaic support structure.

[0039] Furthermore, when the first overlapping section 212 overlaps with the second overlapping section 222, the side of the first overlapping section 212 away from the second overlapping section 222 is flush with both the first connecting section 211 and the second connecting section 221, and the side of the second overlapping section 222 away from the first overlapping section 212 is flush with both the first connecting section 211 and the second connecting section 221, thereby reducing interference with the tiles and improving the adaptability of the photovoltaic support structure.

[0040] Furthermore, the second adjusting arm 220 also includes a second bending section 223. One end of the second bending section 223 is connected to the end of the second connecting section 221 away from the second overlapping section 222, and the other end of the second bending section 223 is connected to the guide rail 300. The second bending section 223 bends relative to the second connecting section 221 along the thickness direction of the tile toward one side of the guide rail 300, thereby raising the height of the guide rail 300 installed on the hook, reducing the interference of the guide rail 300 on the tile, and improving the adaptability of the photovoltaic support structure.

[0041] See Figure 1 and Figure 2 In one embodiment, the first adjusting arm 210 is movable relative to the base 100 in a second direction. The photovoltaic support structure also includes a second fastener 250, which is connected to the first adjusting arm 210 and the base 100. The second fastener 250 is used to fix the position of the first adjusting arm 210 relative to the base 100 in a second direction, wherein the second direction is perpendicular to the first direction and perpendicular to the thickness direction of the tile.

[0042] Specifically, the first adjusting arm 210 can move relative to the base 100 in the second direction to adjust the installation position of the hook 200 on the base 100. This allows the installation position of the hook 200 on the base 100 in the second direction to be adjusted according to the installation position of the purlins on the sloping roof of the house, so as to ensure that the base 100 can be stably installed on the purlins of the sloping roof of the house, thereby improving the adaptability and reliability of the high photovoltaic support structure.

[0043] See Figure 1 and Figure 2 In one embodiment, the base 100 is provided with a second adjustment hole 260 extending in a second direction, and the second fastener 250 passes through the second adjustment hole 260 and is slidably connected to the hole wall of the second adjustment hole 260 in the second direction, thereby guiding the first adjustment arm 210 to move relative to the base 100 in the second direction and improving the accuracy of the first adjustment arm 210 moving relative to the base 100 in the second direction.

[0044] See Figure 1 , Figure 2 and Figure 3 In one embodiment, the first adjusting arm 210 is movable relative to the base 100 in a third direction, and the second fastener 250 is used to fix the first adjusting arm 210 relative to the base 100 in the third direction, wherein the third direction is perpendicular to both the first and second directions, and wherein the third direction is parallel to the thickness direction of the tile.

[0045] Specifically, the first adjusting arm 210 can move relative to the base 100 in a third direction, thereby adjusting the height of the hook in the thickness direction of the tile, thus reducing interference with the tile, and also adjusting the installation height of the guide rail 300, improving the reliability and adaptability of the photovoltaic support structure.

[0046] In this application, the first adjusting arm 210 is fixed relative to the base 100 in the second direction and the third direction upward position by means of the second fastener 250, which simplifies the structure, saves materials, and improves the efficiency of adjusting the installation position of the first adjusting arm 210 relative to the base 100.

[0047] See Figure 1 , Figure 2 and Figure 3 In one embodiment, the first adjusting arm 210 is provided with a third adjusting hole 270 extending in a third direction. The second fastener 250 passes through the third adjusting hole 270 and is slidably connected to the hole wall of the third adjusting hole 270 in a third direction, thereby guiding the movement of the first adjusting arm 210 relative to the base 100 in a third direction and improving the accuracy of the movement of the first adjusting arm 210 relative to the base 100 in a third direction.

[0048] See Figure 1 , Figure 2 and Figure 3In one embodiment, the first adjusting arm 210 further includes a first bent section 213. One end of the first bent section 213 is connected to the end of the first connecting section 211 away from the first overlapping section 212, and the other end of the first bent section 213 is connected to the base 100. The first bent section 213 bends relative to the first connecting section 211 in a third direction away from the guide rail 300. The third adjusting hole 270 is provided on the first bent section 213, thereby reducing the thickness of the first adjusting arm 210 in the third direction and reducing interference with the tile.

[0049] See Figure 1 , Figure 2 and Figure 4 In one embodiment, the guide rail 300 and the second adjusting arm 220 are integrally formed.

[0050] Specifically, the guide rail 300 is connected to the end of the second bent section 223 away from the second connecting section 221. The guide rail 300 and the second adjusting arm 220 are integrally formed, thereby reducing the number of connecting parts between the guide rail 300 and the second adjusting arm 220, simplifying the structure and saving costs.

[0051] The second connecting section 221, the second overlapping section 222 and the second bending section 223 are all integrally formed, and the first connecting section 211, the first overlapping section 212 and the first bending section 213 are all integrally formed.

[0052] See Figure 1 and Figure 2 In one embodiment, the photovoltaic support structure further includes a third fastener. The base 100 has a mounting hole 110, and the third fastener passes through the mounting hole 110 and is used to connect with the sloping roof of the house to fix the base 100 to the sloping roof of the house.

[0053] Specifically, the mounting hole 110 is provided through the third direction, and a third fastener is inserted through the mounting hole 110 and connected to the purlin on the sloping roof of the house, thereby stably fixing the base 100 to the purlin.

[0054] Furthermore, the base 100 includes a mounting plate 120 and a connecting plate 130 connected to each other. The connecting plate 130 is perpendicular to the mounting plate 120. A second adjustment hole 260 is provided on the connecting plate 130, and a mounting hole 110 is provided on the mounting plate 120. Preferably, the connection between the connecting plate 130 and the mounting plate 120 has a rounded transition to avoid stress concentration.

[0055] See Figure 1 and Figure 2In one embodiment, the base 100 is provided with at least two mounting holes 110, which are spaced apart along a first direction. This allows for adjustments to the position of the base 100 relative to the purlins on the sloping roof in the first direction, thereby improving the adaptability of the photovoltaic support structure. Preferably, the base 100 is provided with two mounting holes 110 spaced apart along the first direction.

[0056] Furthermore, the base 100 is provided with at least two mounting holes 110 spaced apart along the second direction, thereby improving the adaptability of the photovoltaic support structure by adjusting the position of the base 100 and the purlins on the sloping roof in the second direction. Preferably, the base 100 is provided with four mounting holes 110 spaced apart along the second direction.

[0057] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent.
