Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, and more specifically, to a photovoltaic power generation system. Background Technology

[0002] As a typical application of BIPV (Building Integrated Photovoltaics), photovoltaic tiles can replace the original building roof tiles. Photovoltaic tiles combine the functions of traditional tiles and photovoltaic power generation. When photovoltaic tiles are laid on the roof of a building, they form a roof photovoltaic system.

[0003] In the prior art, photovoltaic tiles include power generation units and frames installed on the power generation units. During the overlapping process of photovoltaic tiles, the overlapping sections of adjacent photovoltaic tiles are usually the overlapping of power generation units or the overlapping of power generation units with the frame. Since the power generation units are relatively fragile, it is easy to damage the power generation units. Utility Model Content

[0004] The main objective of this invention is to provide a photovoltaic power generation system to solve the problem of damage to the power generation unit when adjacent photovoltaic tiles are overlapped in the prior art.

[0005] To achieve the above objectives, this utility model provides a photovoltaic power generation system. The photovoltaic power generation system includes multiple photovoltaic tiles arranged along the width direction. Each photovoltaic tile includes a power generation body, a first frame, and a second frame. The first frame is located on the upper side of the power generation body, and the second frame is located on the lower side of the power generation body. The second frame of one photovoltaic tile overlaps the first frame of another photovoltaic tile in two adjacent photovoltaic tiles.

[0006] In the above technical solution, by overlapping the second frame of one photovoltaic tile with the first frame of another photovoltaic tile, compared with the prior art where the lower frame of one photovoltaic tile overlaps with the power generation body of another photovoltaic tile, direct contact between the power generation body and the frame, as well as direct contact between the power generation bodies, can be avoided. This avoids the problem of damage to the power generation body due to its fragility, thereby preventing damage to the power generation body, enhancing the stability of the photovoltaic power generation system, and strengthening the roof structure.

[0007] Furthermore, the photovoltaic power generation system also includes a support structure, on which the first frame is mounted.

[0008] In the above technical solution, the support component can securely fix the first frame of the photovoltaic tile when it is installed on the roof. Even under severe weather conditions, the photovoltaic tile can remain stable, reducing the risk of displacement or damage caused by external environmental factors.

[0009] Furthermore, the photovoltaic power generation system also includes mounting components, with the first frame connected to the support components via the mounting components.

[0010] In the above technical solution, on the one hand, the mounting component can ensure a stable connection between the photovoltaic tile and the support component; on the other hand, the photovoltaic tile can be disassembled when maintenance or replacement is required without complicated operations on the support component. This not only simplifies the maintenance process, but also reduces maintenance costs and difficulty.

[0011] Furthermore, the second frame includes a support portion and a stop portion, the stop portion being disposed above the support portion and on a side away from the first frame.

[0012] In the above technical solution, on the one hand, the support part can provide support for the main body of the power generation, ensuring that the main body of the power generation can be firmly fixed on the roof after installation and will not be displaced or deformed due to external forces; on the other hand, through the cooperation of the first frame and the stop part, the movement of the main body of the power generation can be restricted, preventing the main body of the power generation from moving in the width direction, thereby playing a limiting role for the main body of the power generation.

[0013] Furthermore, the first frame is provided with a slot, which engages with the main power generation unit.

[0014] In the above technical solution, by setting a snap-fit ​​slot with the power generation body, the first frame and the power generation body can be quickly and accurately snapped together without a complicated fixing or connection process. This design simplifies the installation process of photovoltaic tiles, improves installation efficiency, and reduces installation costs.

[0015] Furthermore, each photovoltaic tile also includes a third frame and a fourth frame. Along the length direction, the third frame is located on the first side of the power generation body, and the fourth frame is located on the second side of the power generation body. Multiple photovoltaic tiles are arranged along the length direction. The third frame of one of two adjacent photovoltaic tiles overlaps on the fourth frame of another photovoltaic tile. Along the length direction, at least one drainage cavity is formed between the third frame and the fourth frame. The overlapping part of the third frame forms a drainage groove between the side of the third frame facing the fourth frame and the fourth frame. The drainage groove extends from bottom to top to the top surface of the third frame. The drainage cavity and the drainage groove are connected.

[0016] In the above technical solution, the overlapping design between the third and fourth frames allows rainwater to flow from the drainage channel into the drainage chamber. The drainage chamber can effectively drain the rainwater falling between the third and fourth frames, preventing it from easily penetrating into the internal structure of the roof. By setting up the drainage chamber and drainage channel, the drainage efficiency of the photovoltaic tiles can be significantly improved, protecting the roof structure from water damage.

[0017] Furthermore, the third frame includes a first plate segment and a second plate segment connected and arranged at an angle, and the fourth frame includes a third plate segment and a fourth plate segment connected and arranged at an angle. A first protrusion is provided on the lower surface of the first plate segment, and a first recess is provided on the upper surface of the fourth plate segment. The first protrusion and the first recess are provided correspondingly, and the dimension of the first protrusion in the length direction is smaller than the dimension of the first recess in the length direction. A drainage cavity is formed between the sidewall of the first protrusion and the sidewall of the first recess.

[0018] In the above technical solution, the drainage cavity formed by the cooperation structure of the first protrusion and the first recess can effectively collect and guide rainwater to drain out along the width direction, prevent rainwater from accumulating between two adjacent photovoltaic tiles, avoid rainwater infiltration, and significantly improve the overall waterproof performance of the photovoltaic power generation system.

[0019] Furthermore, the lower surface of the third frame of one of the two adjacent photovoltaic tiles is attached to the upper surface of the fourth frame of the other photovoltaic tile, and the attachment position is located on the side of the third frame away from the drainage groove. In the area between the drainage groove and the drainage cavity, there is a gap between the lower surface of the third frame and the upper surface of the fourth frame.

[0020] In the above technical solution, on the one hand, the joint between the third and fourth frames forms a waterproof barrier, which can effectively prevent rainwater from penetrating into the support components, ensuring the waterproofness of the photovoltaic power generation system in rainy weather and protecting the roof structure from water damage; on the other hand, rainwater can effectively enter the drainage cavity through the gaps and then be discharged along the roof, thereby effectively avoiding the accumulation of rainwater between two adjacent photovoltaic tiles.

[0021] Furthermore, each photovoltaic tile also includes multiple connectors for connecting the first frame, second frame, third frame and fourth frame.

[0022] In the above technical solution, the connector can tightly connect the first frame, the second frame, the third frame and the fourth frame to form an integral frame structure, which significantly enhances the structural strength and rigidity of the photovoltaic tile.

[0023] Furthermore, the photovoltaic power generation system also includes multiple water-flow strips, which are spaced apart, and multiple support components are mounted on the multiple water-flow strips.

[0024] In the above technical solution, since the concrete roof in the prior art has unevenness, the water-guiding strip can provide an inclined support surface so that multiple photovoltaic tiles set on the water-guiding strip form an inclined surface. In this way, rainwater on the photovoltaic tiles can be guided to flow along the slope of the roof and help the rainwater to drain out, preventing rainwater from accumulating locally on the roof, effectively improving the drainage efficiency of the roof, and avoiding damage to the photovoltaic tiles and roof structure caused by water accumulation.

[0025] By applying the technical solution of this utility model, the second frame of one photovoltaic tile is overlapped with the first frame of another photovoltaic tile. Compared with the prior art where the lower frame of one photovoltaic tile overlaps with the power generation body of another photovoltaic tile, direct contact between the power generation body and the frame, as well as direct contact between the power generation bodies, can be avoided. This avoids damage to the power generation body due to its fragility, thereby preventing damage to the power generation body, enhancing the stability of the photovoltaic power generation system, and strengthening the roof structure.

[0039] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0040] It should be noted that, in the embodiments of this utility model, the length direction, width direction, and height direction are as follows: Figure 3 and Figure 4 As shown, the length, width, and height directions are set at angles to each other.

[0041] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 9 and Figure 10 As shown, an embodiment of this utility model provides a photovoltaic power generation system. The photovoltaic power generation system includes multiple photovoltaic tiles 10, which are arranged along the width direction. Each photovoltaic tile 10 includes a power generation body 100, a first frame 101, and a second frame 102. The first frame 101 is located on the upper side of the power generation body 100, and the second frame 102 is located on the lower side of the power generation body 100. The second frame 102 of one photovoltaic tile 10 overlaps the first frame 101 of the other photovoltaic tile 10.

[0042] In the above technical solution, by overlapping the second frame 102 of one photovoltaic tile 10 with the first frame 101 of the other photovoltaic tile 10, compared with the prior art where the lower frame of one photovoltaic tile 10 overlaps with the power generation body 100 of the other photovoltaic tile 10, direct contact between the power generation body 100 and the frame, as well as direct contact between the power generation body 100 and the other power generation body 100, can be avoided. This avoids the problem of damage to the power generation body 100 due to its fragility, thereby preventing the destruction of the power generation body 100, enhancing the stability of the photovoltaic power generation system, and strengthening the roof structure.

[0043] Specifically, in the embodiments of this utility model, the power generation body 100 includes a front plate, a front adhesive, a solar cell module, a back adhesive, a back plate, and a junction box. Its structure follows the traditional technical means and will not be described in detail.

[0044] like Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 9 As shown in the embodiment of this utility model, the photovoltaic power generation system further includes a support member 20, and the first frame 101 is mounted on the support member 20.

[0045] In the above technical solution, the support member 20 can ensure that the first frame 101 of the photovoltaic tile 10 is firmly fixed when it is installed on the roof. Even under severe weather conditions, the photovoltaic tile 10 can remain stable, reducing the risk of displacement or damage caused by external environmental factors.

[0046] Specifically, in the embodiments of this utility model, the support member 20 is a tile strip.

[0047] Specifically, in the embodiments of this utility model, such as Figure 3 As shown, there are multiple support members 20, which are spaced apart along the width direction.

[0048] like Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 9 As shown in the embodiment of this utility model, the photovoltaic power generation system further includes an installation component 40, and the first frame 101 is connected to the support component 20 through the installation component 40.

[0049] In the above technical solution, on the one hand, the mounting component 40 can ensure a stable connection between the photovoltaic tile 10 and the support component 20; on the other hand, when the photovoltaic tile 10 needs maintenance or replacement, the mounting component 40 can be disassembled without complicated operations on the support component 20, which not only simplifies the maintenance process, but also reduces maintenance costs and difficulty.

[0050] Specifically, in the embodiments of this utility model, the mounting component 40 is a screw, and multiple mounting components 40 are provided.

[0051] In some embodiments, the first frame 101 can be connected to the support member 20 by riveting, snap-fitting or pin connection.

[0052] like Figure 1 , Figure 4 , Figure 5 and Figure 10 As shown in the embodiment of the present invention, the second frame 102 includes a support portion 1021 and a stop portion 1022. The stop portion 1022 is disposed above the support portion 1021 and is disposed on the side away from the first frame 101.

[0053] In the above technical solution, on the one hand, the support part 1021 can provide support for the power generation body 100, ensuring that the power generation body 100 can be firmly fixed on the roof after installation and will not be displaced or deformed due to external forces; on the other hand, through the cooperation of the first frame 101 and the stop part 1022, the movement of the power generation body 100 can be restricted, preventing the power generation body 100 from moving in the width direction, thereby playing a limiting role for the power generation body 100.

[0054] Specifically, in the embodiments of this utility model, the stop portion 1022 is provided with structural adhesive on the side facing the power generation body 100.

[0055] like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 9 As shown in the embodiment of this utility model, the first frame 101 is provided with a slot, which is engaged with the power generation body 100.

[0056] In the above technical solution, by setting a snap-fit ​​slot with the power generation body 100, the first frame 101 and the power generation body 100 can be quickly and accurately snapped together without a complicated fixing or connection process. This design simplifies the installation process of the photovoltaic tile 10, improves installation efficiency, and reduces installation costs.

[0057] Specifically, in the embodiments of this utility model, the side of the card slot facing the power generation body 100 is provided with sealant.

[0058] In existing technology, rainwater flows down and is discharged along the width direction. However, some rainwater remains between two adjacent photovoltaic tiles 10 along the length direction and is difficult to discharge. Therefore, if... Figure 1 , Figure 3 , Figure 6 , Figure 7 and Figure 8 As shown in the embodiment of this utility model, each photovoltaic tile 10 further includes a third frame 103 and a fourth frame 104. Along the length direction, the third frame 103 is disposed on the first side of the power generation body 100, and the fourth frame 104 is disposed on the second side of the power generation body 100. Multiple photovoltaic tiles 10 are arranged along the length direction. The third frame 103 of one photovoltaic tile 10 overlaps with the fourth frame 104 of another photovoltaic tile 10. Along the length direction, at least one drainage cavity 11 is formed between the third frame 103 and the fourth frame 104. The overlapping part of the third frame 103 forms a drainage groove 12 between the side of the third frame 103 facing the fourth frame 104 and the fourth frame 104. The drainage groove 12 extends from bottom to top to the top surface of the third frame 103. The drainage cavity 11 and the drainage groove 12 are connected.

[0059] In the above technical solution, the overlapping design between the third frame 103 and the fourth frame 104 allows rainwater to flow from the drainage channel 12 into the drainage chamber 11. The drainage chamber 11 can effectively drain the rainwater falling between the third frame 103 and the fourth frame 104, and it is not easy for the rainwater to penetrate into the internal structure of the roof. By setting the drainage chamber 11 and the drainage channel 12, the drainage efficiency of the photovoltaic tile 10 can be significantly improved, and the roof structure can be protected from water damage.

[0060] Specifically, in the embodiments of this utility model, the overlapping of the third frame 103 and the fourth frame 104 forms a drainage cavity 11, which not only improves drainage efficiency, but also increases the structural stability between two adjacent photovoltaic tiles 10. The overlapping of the frames of two adjacent photovoltaic tiles 10 forms a stable connection, reducing displacement or damage caused by external forces.

[0061] like Figure 1 , Figure 6 , Figure 7 and Figure 8As shown in the embodiment of this utility model, the third frame 103 includes a first plate segment 1031 and a second plate segment 1032 connected and arranged at an angle, and the fourth frame 104 includes a third plate segment 1041 and a fourth plate segment 1042 connected and arranged at an angle. A first protrusion 1033 is provided on the lower surface of the first plate segment 1031, and a first recess 1044 is provided on the upper surface of the fourth plate segment 1042. The first protrusion 1033 and the first recess 1044 are correspondingly arranged, and the dimension of the first protrusion 1033 in the length direction is smaller than the dimension of the first recess 1044 in the length direction. A drainage cavity 11 is formed between the sidewall of the first protrusion 1033 and the sidewall of the first recess 1044.

[0062] In the above technical solution, the drainage cavity 11 formed by the cooperation structure of the first protrusion 1033 and the first recess 1044 can effectively collect and guide rainwater to be discharged along the width direction, prevent rainwater from accumulating between two adjacent photovoltaic tiles 10, avoid rainwater penetration, and significantly improve the overall waterproof performance of the photovoltaic power generation system.

[0063] Specifically, in the embodiments of this utility model, a second recessed portion 1034 is provided on the lower surface of the first plate segment 1031, and a second protruding portion 1043 is provided on the upper surface of the fourth plate segment 1042. The second recessed portion 1034 and the second protruding portion 1043 are correspondingly arranged, and the dimension of the second protruding portion 1043 in the length direction is smaller than the dimension of the second recessed portion 1034 in the length direction. A drainage cavity 11 is formed between the side wall of the second protruding portion 1043 and the side wall of the second recessed portion 1034. By providing multiple protruding portions and multiple recessed portions, the drainage area can be increased and the drainage efficiency can be improved.

[0064] Specifically, in the embodiments of this utility model, when installing two adjacent photovoltaic tiles 10, there is an movable gap between the third frame 103 of one photovoltaic tile 10 and the fourth frame 104 of the other photovoltaic tile 10. The third frame 103 of one photovoltaic tile 10 can move relative to the fourth frame 104 of the other photovoltaic tile 10 along the length direction, which can reduce the installation error of the two adjacent photovoltaic tiles. When the photovoltaic tile 10 is fixed to the support member 20 by the mounting member 40, the position of the photovoltaic tile 10 is fixed.

[0065] like Figure 7 and Figure 8 As shown in the embodiment of this utility model, the third frame 103 is provided with a slot, which is engaged with the power generation body 100; the fourth frame 104 is provided with a slot, which is engaged with the power generation body 100.

[0066] like Figure 1 , Figure 6 , Figure 7 and Figure 8 As shown in the embodiment of this utility model, the lower surface of the third frame 103 of one of the two adjacent photovoltaic tiles 10 is attached to the upper surface of the fourth frame 104 of the other photovoltaic tile 10, and the attachment position is located on the side of the third frame 103 away from the drainage groove 12. In the area between the drainage groove 12 and the drainage cavity 11, there is a gap between the lower surface of the third frame 103 and the upper surface of the fourth frame 104.

[0067] In the above technical solution, on the one hand, the contact position between the third frame 103 and the fourth frame 104 forms a waterproof barrier, which can effectively prevent rainwater from penetrating into the support member 20, ensuring the waterproofness of the photovoltaic power generation system in rainy weather and protecting the roof structure from water damage; on the other hand, rainwater can effectively enter the drainage cavity 11 through the gap and then be discharged along the roof, thereby effectively avoiding the accumulation of rainwater between two adjacent photovoltaic tiles 10.

[0068] Specifically, in the embodiments of this utility model, a gap is left near the drainage cavity 11 to allow rainwater to flow along the gap toward the drainage cavity 11. With the design of the drainage cavity 11, a rapid drainage effect can be achieved.

[0069] like Figure 1 , Figure 4 , Figures 5 to 10 As shown in the embodiments of this utility model, each photovoltaic tile 10 also includes a plurality of connectors 105, which are used to connect the first frame 101, the second frame 102, the third frame 103 and the fourth frame 104.

[0070] In the above technical solution, the connector 105 can tightly connect the first frame 101, the second frame 102, the third frame 103 and the fourth frame 104 to form an integral frame structure, which significantly enhances the structural strength and rigidity of the photovoltaic tile 10.

[0071] Specifically, in the embodiments of this utility model, there are four connectors 105. Each connector 105 includes a fifth plate segment and a sixth plate segment that are connected and arranged at an angle. The fifth plate segment and the sixth plate segment are used to connect two different frames.

[0072] Specifically, in the embodiments of this utility model, the connector 105 is a corner bracket.

[0073] like Figures 3 to 5 As shown in the embodiment of this utility model, the photovoltaic power generation system further includes a plurality of water-following strips 30, which are spaced apart, and a plurality of support members 20 are disposed on the plurality of water-following strips 30.

[0074] In the above technical solution, since the concrete roof in the prior art has unevenness, the water-guiding strip 30 can provide an inclined support surface so that the multiple photovoltaic tiles 10 set on the water-guiding strip 30 form an inclined surface. In this way, rainwater on the photovoltaic tiles 10 can be guided to flow along the slope of the roof and help the rainwater to drain out, preventing rainwater from accumulating locally on the roof, effectively improving the drainage efficiency of the roof, and avoiding damage to the photovoltaic tiles 10 and the roof structure caused by water accumulation.

[0075] Specifically, in the embodiments of this utility model, the water-following strip 30 is set on the concrete roof by screws, and multiple support members 20 are set on multiple water-following strips 30 by screws.

[0076] Specifically, this utility model provides a photovoltaic power generation system with superior waterproof performance, convenient installation, low cost, and reliable fixation. When used on a roof, the first frame 101 increases the overlap length of the overlapping section of adjacent photovoltaic tiles 10, effectively enhancing the waterproof performance of the pitched roof. When used on a roof, the novel third frame 103 and fourth frame 104 allow the frames of adjacent photovoltaic tiles to overlap vertically, combining water blocking and drainage functions, effectively enhancing the waterproof performance of the pitched roof.

[0077] Specifically, in the embodiments of this utility model, the first frame 101 of the photovoltaic tile 10 can be fixed on the support member 20 with the help of the mounting member 40. The installation is convenient, low-cost, and reliable, and there is no risk of damaging the photovoltaic tile 10. The structure of the photovoltaic tile 10 composed of the first frame 101, the second frame 102, the third frame 103 and the fourth frame 104 is more stable.

[0078] Specifically, in this embodiment of the invention, the roof is in an unorganized drainage state during rainy weather. A drainage cavity 11 is provided between adjacent left and right photovoltaic tiles 10, from which rainwater is discharged along the width direction, thereby enhancing the roof's waterproofing effect. The unique design of the third frame 103 and the fourth frame 104 of this invention ensures excellent compatibility with installation errors during construction. When there is a deviation in the position of adjacent left and right photovoltaic tiles, it allows for normal assembly between adjacent photovoltaic tiles 10, guaranteeing the waterproofing effect of the photovoltaic power generation system.

[0079] Specifically, in the embodiments of this utility model, the design of the first protrusion 1033 and the second recess 1034 of the third frame 103, and the design of the first recess 1044 and the second protrusion 1043 of the fourth frame 104, can adapt the photovoltaic tile 10 to work with traditional tiles and together form a pitched roof.

[0080] As can be seen from the above description, the above-described embodiments of this utility model achieve the following technical effects: by overlapping the second frame of one photovoltaic tile with the first frame of another photovoltaic tile, compared with the prior art where the lower frame of one photovoltaic tile overlaps with the power generation body of another photovoltaic tile, direct contact between the power generation body and the frame, as well as direct contact between the power generation bodies, can be avoided. This avoids the problem of damage to the power generation body due to its fragility, thereby preventing damage to the power generation body, enhancing the stability of the photovoltaic power generation system, and strengthening the stability of the roof structure.

[0081] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
