Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, and in particular to a frame component and a photovoltaic roof equipped with it. Background Technology

[0002] Photovoltaic roofing tiles are a type of building material that combines solar photovoltaic technology with roofing tiles. Compared to traditional tiles, photovoltaic tiles prioritize harmony with the building's appearance and offer diverse color and size options to meet the needs of different architectural styles. When applied to buildings, photovoltaic tiles not only retain the basic functions of traditional tiles, such as rain protection, wind resistance, and insulation, but also offer additional attributes such as clean energy, easy installation, lightweight, safety, durability, heat insulation, and aesthetics. However, in current installation methods, the top and bottom edges of photovoltaic tiles typically meet directly, creating a seam that allows water to easily seep into the roof or interior, posing a significant drawback for rooftop photovoltaic applications. Utility Model Content

[0003] In view of this, the present invention aims to provide a frame component that can cover the splicing gaps, prevent rainwater from seeping down from the splicing gaps, and improve practicality and safety.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A border component, comprising a top border and a bottom border;

[0006] A frame mounting groove is formed on one side of the upper frame for mounting the upper side of the photovoltaic tile. In the normal direction of the photovoltaic tile, the frame mounting groove is opened and forms an installation opening facing the light-facing side of the photovoltaic tile.

[0007] One side of the lower frame is formed with a lower insertion groove for inserting the lower side of the photovoltaic tile, and the side of the lower frame away from the lower insertion groove is provided with a receiving structure. The receiving structure includes a receiving cavity with an opening away from the lower insertion groove. The receiving structure allows another upper frame to be inserted and dock with the lower frame.

[0008] Furthermore, the side wall of the upper frame located on the light-facing side is the light-facing side, and the accommodating structure includes at least a shielding part located on the light-facing side, the shielding part being used to shield the area above the mounting opening of the upper frame.

[0009] Furthermore, the shielding part is an overlapping plate, which is disposed on the side of the lower frame away from the lower insertion groove; along the height direction of the lower frame, the overlapping plate is located above the lower frame, and the overlapping plate can overlap the top of the adjacent upper frame so that two adjacent photovoltaic tiles can be connected together.

[0010] Furthermore, the upper frame includes a first base and a frame side plate disposed on the first base. The first base includes a bearing surface for supporting the photovoltaic tile, and the frame side plate is disposed on the bearing surface. The first base and the frame side plate together form the frame mounting groove. The lower frame includes a second top plate and a second base arranged opposite to each other, and a second connecting plate connected between the second base and the second top plate. The lower insertion groove is formed between the second top plate, the second base, and the second connecting plate. The overlapping plate is located on the side of the second connecting plate away from the lower insertion groove. Along the height direction of the lower frame, the overlapping plate covers the frame side plate.

[0011] Furthermore, the side of the overlapping plate facing the frame mounting groove is the overlapping surface, and the side of the second top plate facing the second base is the insertion surface, with the overlapping surface and the insertion surface being coplanar; or, the side of the overlapping plate facing the frame mounting groove is the overlapping surface, and the side of the second top plate facing the second base is the insertion surface, with the distance from the overlapping surface to the second base being greater than the distance from the insertion surface to the second base.

[0012] Furthermore, a sealing element is provided on the side of the shielding portion facing the upper frame, and / or a sealing element is provided on the top of the upper frame; the sealing element is used to seal the splicing gap between the shielding portion and the upper frame.

[0013] Compared with the prior art, this utility model has the following advantages:

[0014] (1) The frame assembly described in this utility model, through the setting of the lower insertion groove, facilitates the installation of the lower frame on the lower side of the photovoltaic tile. By setting the frame mounting groove, when two adjacent photovoltaic modules are connected, the upper side of the lower photovoltaic module can be directly placed in the frame mounting groove through the installation port, which is simple and convenient to operate. At the same time, the accommodating structure with the accommodating cavity is set, which allows the upper frame of the lower photovoltaic module to be inserted into the accommodating cavity and connected with the lower frame of the upper photovoltaic module to form a plug-in installation form. This not only facilitates the connection between two adjacent photovoltaic tiles and improves the ease of disassembly and assembly, but also helps to ensure the sealing between the two, improves the wind resistance and waterproof performance of the photovoltaic tile, and reduces the risk of rainwater seepage and backflow. This can help improve the daily use effect of the photovoltaic tile and facilitate its later maintenance and replacement.

[0015] (2) The housing structure includes a shielding part located on the light-facing side, which can shield the splicing gap between the upper frame and the lower frame, thereby ensuring the sealing between two adjacent photovoltaic tiles, blocking rainwater, preventing it from seeping into the bottom of the photovoltaic module from the splicing gap, and also achieving aesthetic connection.

[0016] (3) The shading part adopts an overlapping plate, which has a simple structure, is conducive to cost reduction, and facilitates the docking operation between two adjacent photovoltaic tiles. At the same time, the overlapping plate can overlap the top of the adjacent upper frame, which is also conducive to the two adjacent photovoltaic tiles being docked together flat. Thus, the overlapping plate can block rainwater and prevent rainwater from seeping into the bottom of the photovoltaic module from the splicing gap. In turn, the rainwater can be diverted to the upper surface of the photovoltaic module to wash away the dust on the surface of the photovoltaic module.

[0017] (4) The upper frame includes a frame side plate and a first base, and the lower frame includes a second top plate, a second base, and a second connecting plate, which facilitates the formation of a frame mounting groove and a lower insertion groove. The overlapping plate is located on the side of the second connecting plate away from the lower insertion groove and overlaps on the frame side plate. The structural design is reasonable and facilitates the simplification of the docking operation between the upper and lower frames. At the same time, the setting of the bearing surface facilitates the formation of a better support effect for the photovoltaic tile and ensures the reliability of the photovoltaic tile in subsequent use.

[0018] (5) The overlapping surface and the plugging surface are set on the same plane, or the distance from the overlapping surface to the second base is greater than the distance from the plugging surface to the second base, which can facilitate the formation of a flush connection between two adjacent photovoltaic tiles.

[0019] (6) A sealing element is provided to seal the gap between the shield and the upper frame, which helps to ensure the sealing between the upper and lower frames after they are joined, and also helps to ensure the sealing between two adjacent photovoltaic tiles.

[0020] This utility model also proposes a photovoltaic roof, including photovoltaic modules;

[0021] The photovoltaic module has a photovoltaic tile and a frame assembly as described above disposed on the photovoltaic tile.

[0022] Furthermore, it also includes an installation structure for installing the photovoltaic modules; the installation structure includes purlins and a plurality of longitudinal beams arranged sequentially on the purlins, with the photovoltaic modules disposed between two adjacent longitudinal beams, and the photovoltaic modules being a plurality of modules sequentially connected along the length direction of the longitudinal beams.

[0023] Furthermore, the longitudinal beam includes a lower profile and a cover plate; the lower profile includes a mounting portion disposed on the purlin and a support portion disposed on the top of the mounting portion, and the cover plate is disposed on the support portion; a side mounting groove is formed between the mounting portion, the support portion and the cover plate, and the support portion is provided with the side mounting groove on both sides along the width direction of the longitudinal beam, and each of the side mounting grooves is used to install the photovoltaic module.

[0024] Furthermore, along the width direction of the longitudinal beam, the mounting portion is provided with a plurality of drainage channels located on both sides of the support portion, and each of the side mounting grooves is connected to at least one of the drainage channels on the same side; and / or, it also includes a stop member provided at the bottom of the longitudinal beam, the stop member being used to prevent the photovoltaic module from slipping out of the side mounting groove.

[0025] (7) The photovoltaic roof described in this utility model, by adopting the above-mentioned frame components, can facilitate the convenient disassembly and assembly of two adjacent photovoltaic tiles, and help ensure the sealing between the two, improve the wind resistance and waterproof performance of the photovoltaic tiles, reduce the risk of rainwater backflow, thereby improving the daily use effect of the photovoltaic tiles, and facilitating their later maintenance and replacement.

[0026] (8) Inserting photovoltaic modules between two adjacent mounting slots, and having multiple photovoltaic modules connected sequentially along the length of the longitudinal beam, can make the layout reasonable and facilitate the construction of photovoltaic roofs.

[0027] (9) By forming a side mounting groove between the mounting part, the support part and the cover plate, it is easy to install photovoltaic modules.

[0028] (10) A drainage channel is set on the installation section to realize the drainage function of the longitudinal beam, reduce the risk of rainwater backflow, and solve the problem of poor rain and backflow prevention function of existing photovoltaic tiles, which is prone to leakage. At the same time, the setting of the baffle can prevent the photovoltaic module from slipping off and improve the installation reliability of the photovoltaic module. Attached Figure Description

In addition, if terms such as "first" or "second" appear, they are also used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0050] Furthermore, in the description of this utility model, unless otherwise explicitly defined, the terms "installation," "connection," "joining," and "connector" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0052] The present invention will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0053] An embodiment of the first aspect of this utility model provides a frame assembly that facilitates the flush docking of two adjacent photovoltaic tiles 301, thereby facilitating the daily maintenance and replacement of the photovoltaic tiles 301.

[0054] In the existing technology, the upper frame 303 and the lower frame 304 of the photovoltaic tile 301 are in direct contact, and the contact point forms a splicing gap. Water can easily seep into the roof or the house from this gap, making it difficult to guarantee the basic functions of the photovoltaic roof such as rainproof, windproof, and heat insulation.

[0055] In view of this, in order to overcome the shortcomings of the prior art, the border component of this embodiment combines... Figure 1 , Figures 3 to 6 As shown, in terms of overall design, it includes an upper border 303 and a lower border 304.

[0056] The upper frame 303 has a frame mounting groove 3031 on one side for mounting the upper side of the photovoltaic tile 301. The frame mounting groove 3031 is open on the light-facing side of the photovoltaic tile 301, forming an mounting opening. The lower frame 304 has a lower insertion groove 3044 on one side for inserting the lower side of the photovoltaic tile 301. A receiving structure is provided on the side of the lower frame 304 opposite to the lower insertion groove 3044. The receiving structure includes a receiving cavity 3040 with an opening opposite to the lower insertion groove 3044. The receiving structure allows another upper frame 303 to be inserted and then dock with the lower frame 304.

[0057] Therefore, by setting the lower insertion slot 3044, it is convenient to install the lower frame 304 on the lower side of the photovoltaic tile 301. By setting the frame mounting slot 3031, when two adjacent photovoltaic modules 300 are connected, the upper side of the lower photovoltaic module 300 can be directly placed into the frame mounting slot 3031 through the mounting port, which is simple and convenient. At the same time, the accommodating structure with the receiving cavity 3040 is set so that the upper frame 303 of the lower photovoltaic module 300 can be inserted into the receiving cavity 3040 and then connected to the upper photovoltaic module 301. The bottom frame 304 of the 00 model forms a plug-in installation, which not only facilitates the connection between two adjacent photovoltaic tiles 301, improving the ease of installation and removal, but also ensures the airtightness between them, improving the wind resistance and waterproof performance of the photovoltaic tile 301. It can also cover the splicing gaps to prevent rainwater from seeping downwards from the splicing gaps, improving practicality and safety, and reducing the risk of rainwater seepage and backflow. This can improve the daily use effect of the photovoltaic tile 301, as well as facilitate its later maintenance and replacement.

[0058] Based on the above overview, in this embodiment, in some exemplary implementations, the frame assembly is applied to the photovoltaic tile 301. Besides including the upper frame 303 and the lower frame 304, the frame assembly also includes, for example... Figure 3 and Figure 7 As shown, it also includes side frames 302 disposed on the left and right sides of the photovoltaic tile 301, so that the frame components and the photovoltaic tile 301 constitute a photovoltaic module 300.

[0059] In some exemplary embodiments, in this embodiment, the upper frame 303 is located on the side wall of the light-facing surface, which is the light-facing side. The accommodating structure includes at least a shielding part located on the light-facing side, which is used to shield the area above the mounting opening of the upper frame 303.

[0060] Understandably, the housing structure includes a shading part located on the sun-facing side, which can block the splicing gap between the upper frame 303 and the lower frame 304, thereby ensuring the sealing between two adjacent photovoltaic tiles 301, blocking rainwater, preventing it from seeping into the bottom of the photovoltaic module 300 from the splicing gap, and also achieving aesthetic connection.

[0061] In specific implementations, in some exemplary embodiments, the shielding part of this embodiment is an overlapping plate 3045, which is disposed on the side of the lower frame 304 opposite to the lower insertion slot 3044. Along the height direction of the lower frame 304, the overlapping plate 3045 is located above the lower frame 304, and the overlapping plate 3045 can overlap the top of the adjacent upper frame 303 so that two adjacent photovoltaic tiles 301 are connected together.

[0062] Here, the use of an overlapping plate 3045 in the shielding section simplifies the structure, reduces costs, and facilitates the docking operation between two adjacent photovoltaic tiles 301. At the same time, the overlapping plate 3045 can overlap the top of the adjacent upper frame 303, which also facilitates the flush docking of two adjacent photovoltaic tiles 301. The overlapping plate 3045 shields rainwater, preventing rainwater from seeping into the lower part of the photovoltaic module 300 from the splicing gap, and can also divert rainwater to the upper surface of the photovoltaic module 300 to wash away dust on the surface of the photovoltaic module 300.

[0063] Furthermore, in some of the exemplary embodiments, this embodiment still follows... Figures 4 to 6 As shown, the upper frame 303 includes a first base 3032 and a frame side plate 3033 disposed on the first base 3032. The first base 3032 includes a bearing surface 30321 for supporting the photovoltaic tile 301. The frame side plate 3033 is disposed on the bearing surface 30321. The first base 3032 and the frame side plate 3033 together form a frame mounting groove 3031.

[0064] Furthermore, the lower frame 304 includes a second top plate 3041 and a second base 3042 arranged vertically opposite each other, and a second connecting plate 3043 connecting the second base 3042 and the second top plate 3041. A lower insertion groove 3044 is formed between the second top plate 3041, the second base 3042, and the second connecting plate 3043. An overlapping plate 3045 is located on the side of the second connecting plate 3043 away from the lower insertion groove 3044, and along the height direction of the lower frame 304, the overlapping plate 3045 covers the upper part of the frame side plate 3033.

[0065] The main advantage of this design is that it facilitates the formation of the frame mounting groove 3031 and the lower insertion groove 3044. The overlapping plate 3045 is located on the side of the second connecting plate 3043 away from the lower insertion groove 3044 and covers the frame side plate 3033. This rational structural design simplifies the docking operation between the upper frame 303 and the lower frame 304. Simultaneously, the placement of the bearing surface 30321 provides better support for the photovoltaic tile 301, ensuring the reliability of the photovoltaic tile 301 in subsequent use.

[0066] Of course, in this embodiment, the idea that two adjacent photovoltaic tiles 301 are flush together means that the upper and / or lower surfaces of two adjacent photovoltaic tiles 301 are basically flush, that is, the two adjacent photovoltaic tiles 301 can form a flat arrangement.

[0067] Still Figure 4 As shown, in some exemplary embodiments, in this example, the side of the overlapping plate 3045 facing the frame mounting groove 3031 is the overlapping surface 30451, and the side of the second top plate 3041 facing the second base 3042 is the insertion surface 30411. The distance between the overlapping surface 30451 and the second base 3042 is greater than the distance between the insertion surface 30411 and the second base 3042. This facilitates the formation of a flush-joined arrangement of two adjacent photovoltaic tiles 301.

[0068] Of course, in order to achieve flush connection between two adjacent photovoltaic tiles 301, in addition to the above-mentioned arrangement, other arrangements that can also achieve flush connection between two adjacent photovoltaic tiles 301 can also be adopted. For example, in some exemplary embodiments, the side of the overlapping plate 3045 facing the frame mounting groove 3031 is the overlapping surface 30451, and the side of the second top plate 3041 facing the second base 3042 is the insertion surface 30411. The overlapping surface 30451 and the insertion surface 30411 are coplanar.

[0069] Meanwhile, in some exemplary embodiments of this invention, both the first base 3032 and the second base 3042 are hollow, and if necessary, the bottoms of both the first base 3032 and the second base 3042 are open, which facilitates the weight reduction design of the frame components.

[0070] Furthermore, in some exemplary embodiments, this embodiment still follows... Figure 4 As shown, a sealing element 305 is provided on the side of the shielding part facing the upper frame 303, or a sealing element 305 is provided on the top of the upper frame 303. The sealing element 305 is used to seal the splicing gap between the shielding part and the upper frame 303.

[0071] By setting a sealing element 305 that can seal the splicing gap between the shielding part and the upper frame 303, it is beneficial to ensure the sealing performance after the upper frame 303 and the lower frame 304 are connected, which is also beneficial to ensure the sealing performance between two adjacent photovoltaic tiles 301.

[0072] Of course, in this embodiment, in order to ensure the sealing between the upper frame 303 and the lower frame 304, a sealing element 305 may be provided on the side of the shielding part facing the upper frame 303 if necessary. At the same time, a sealing element 305 is also provided on the top of the upper frame 303.

[0073] A second aspect of this utility model provides a photovoltaic roof, which includes a photovoltaic module 300. The photovoltaic module 300 has a photovoltaic tile 301 and the aforementioned frame assembly disposed on the photovoltaic tile 301.

[0074] In some of these exemplary implementations, reference continues to be made to... Figure 1 As shown, the photovoltaic roof of this embodiment also includes a roof body 400 and an installation structure for mounting photovoltaic modules 300 disposed on the roof body 400. The installation structure includes purlins 100 and longitudinal beams 200 disposed on the purlins 100. Specifically, the purlins 100 may include transversely arranged purlins 100 and longitudinally arranged purlins 100 to ensure the structural stability of the installation structure.

[0075] In some exemplary embodiments, in this example, the longitudinal beams 200 are arranged in sequence. Photovoltaic modules 300 are inserted between the side mounting slots 203 of two adjacent longitudinal beams 200, and the photovoltaic modules 300 are arranged in sequence along the length of the longitudinal beams 200.

[0076] It is understandable that inserting the photovoltaic modules 300 between two adjacent side mounting slots 203, and having multiple photovoltaic modules 300 connected sequentially along the length of the longitudinal beam 200, can make the layout reasonable and facilitate the construction of the photovoltaic roof.

[0077] Based on the above overall introduction, specifically, as an exemplary structural form, in the longitudinal beam 200 of this embodiment, combined with... Figure 2 , Figure 9 As shown, in the overall design, it is located on the purlin 100 in the photovoltaic roof and includes a lower profile 201 and a cover plate 202.

[0078] The lower profile 201 includes a mounting portion on the purlin 100 and a support portion 2012 on top of the mounting portion. A cover plate 202 is provided on the support portion 2012, and a side mounting groove 203 is formed between the mounting portion, the support portion 2012, and the cover plate 202. Side mounting grooves 203 are provided on both sides of the support portion 2012 along the width direction of the longitudinal beam 200, and each side mounting groove 203 is used to mount the photovoltaic module 300. Therefore, by forming the side mounting groove 203 between the mounting portion, the support portion 2012, and the cover plate 202, the installation of the photovoltaic module 300 can be facilitated.

[0079] Meanwhile, in this embodiment, in specific implementation, the cover plate 202 can be detachably mounted on the support portion 2012, for example... Figure 9 As shown, the cover plate 202 and the support part 2012 are connected by the connector 205, which facilitates the easy disassembly and assembly of the cover plate 202, thereby improving the ease of disassembly and assembly of the photovoltaic module 300, which is beneficial to the daily use and maintenance of the photovoltaic tile 301.

[0080] Of course, the aforementioned connector 205 can be made of self-tapping screws. Furthermore, the number and arrangement of the connectors 205 can be set and adjusted according to the actual installation requirements of the cover plate 202 and the lower profile 201. For example, multiple connectors 205 can be arranged at intervals along the length of the longitudinal beam 200.

[0081] In some exemplary embodiments, corresponding to the side mounting slots 203, the mounting portion of this embodiment has a receiving side. Therefore, when using the longitudinal beams 200 in this embodiment, the lower profile 201 can be first fastened to the purlin 100 with automatic screws, and then the photovoltaic module 300 can be laid on the receiving side of two adjacent longitudinal beams 200. The cover plate 202 is then installed on the lower profile 201, thereby installing the photovoltaic tile 301 assembly in two adjacent side mounting slots 203. Furthermore, when it is necessary to repair or replace the photovoltaic module 300, simply removing the cover plate 202 allows for the placement and removal of the photovoltaic module 300.

[0082] It should be noted that the direction-related descriptions in this embodiment are merely illustrative examples. In actual implementation, the direction descriptions in this embodiment will vary depending on the orientation of the longitudinal beam 200; that is, each direction in this embodiment refers to a relative coordinate system based on the longitudinal beam 200.

[0083] In some of the exemplary embodiments, in this embodiment, combined with Figure 2 , Figure 7 and Figure 9As shown, the support portion 2012 includes two opposing second side plates 20121 disposed on the top of the mounting portion, and a support connecting plate 20122 disposed between the two second side plates 20121. The support connecting plate 20122 is located on top of the two second side plates 20121, and the cover plate 202 is in contact with the support connecting plate 20122.

[0084] It is understandable that by setting the second side plate 20121, it is possible to form a side mounting groove 203 between the mounting part, the support part 2012 and the cover plate 202. At the same time, the cover plate 202 is abutted and connected to the support connecting plate 20122, which makes the structure simple and easy to operate.

[0085] Furthermore, in this embodiment, in some exemplary implementations, it is still as follows Figure 7 and Figure 9 As shown, the mounting section includes a mounting section body 2011. The mounting section body 2011 includes a mounting base plate 20111, two first side plates 20112 arranged opposite each other along the width direction of the longitudinal beam 200 and disposed on the mounting base plate 20111, and a mounting top plate 20113 disposed between the two first side plates 20112. A support portion 2012 is disposed on the mounting top plate 20113. Furthermore, a cavity is formed between the mounting base plate 20111, the mounting top plate 20113, and the two first side plates 20112 to facilitate weight reduction of the longitudinal beam 200.

[0086] In some exemplary embodiments, in this embodiment, along the width direction of the longitudinal beam 200, the mounting part is provided with a plurality of drainage channels 2013 located on both sides of the support part 2012, and each side mounting groove 203 is connected to at least one of the drainage channels 2013 on the same side.

[0087] In detail, the mounting base plate 20111 is provided with multiple first side plates 20112 on both sides of the support part 2012, and two adjacent first side plates 20112 in the middle, together with the mounting base plate 20111 and the mounting top plate 20113, form the cavity. At the same time, in each of the first side plates 20112 on both sides, the drainage channel 2013 is formed between two adjacent first side plates 20112 and the mounting base plate 20111.

[0088] Moreover, as a preferred embodiment, the mounting top plate 20113 of this embodiment is also provided with a drainage channel 2013, and the mounting top plate 20113 is provided with the drainage channel 2013 on both sides of the support part 2012, so as to ensure the drainage performance of the longitudinal beam 200, reduce the risk of rainwater backflow, solve the problem of poor rain and backflow prevention function of the existing photovoltaic tile 301 and easy leakage, and also provide compensation space for the deformation of the photovoltaic module 300.

[0089] In some of the exemplary embodiments, in this embodiment, combined with Figure 3 and Figure 7 As shown above, the photovoltaic module 300 includes a photovoltaic tile 301, an upper frame 303 on the upper side of the photovoltaic tile 301, a lower frame 304 on the lower side of the photovoltaic tile 301, and side frames 302 on both sides of the photovoltaic tile 301 along the width direction of the longitudinal beam 200. Each side frame 302 is provided with a slot 3020 for engaging the photovoltaic tile 301.

[0090] In specific implementations, in some exemplary embodiments, in this example, the side frame 302 includes a side frame base 3021 and a first top plate 3022, and a first connecting plate 3023 connecting the side frame base 3021 and the first top plate 3022. A slot 3020 is formed between the side frame base 3021, the first top plate 3022, and the first connecting plate 3023. The side frame base 3021 is hollow and has an opening at the bottom to facilitate weight reduction and ensure the drainage reliability of each drainage channel 2013.

[0091] It should be noted that, Figure 8 The image shows the side frame 302 installed on the left side of the photovoltaic tile 301. Since the left side frame 302 and the right side frame 302 have basically the same structure and can be regarded as mirror images of each other, the right side frame 302 will not be shown separately here.

[0092] If necessary, still as Figure 7 As shown, a sealing element 305 can be provided between each side frame 302 and the cover plate 202 to increase the sealing performance and prevent rainwater from flowing into the side mounting groove 203. This sealing element 305 and the sealing element 305 between the upper frame 303 and the lower frame 304 can both be sealing strips.

[0093] Furthermore, in some exemplary embodiments, this embodiment combines... Figure 1 and Figure 2 As shown, the mounting structure includes a retaining member 204 located at the bottom of the longitudinal beam 200. The retaining member 204 is used to prevent the photovoltaic module 300 from slipping out of the side mounting groove 203. The retaining member 204 is connected to the support part 2012 by a fastening assembly.

[0094] This configuration not only improves the installation reliability of the photovoltaic module 300, but also facilitates the easy assembly and disassembly of the retaining member 204 and the support part 2012 by connecting the retaining member 204 to the support part 2012 through the fastening component.

[0095] Meanwhile, in some exemplary embodiments, a drainage gap corresponding to each side mounting groove 203 is formed between the bottom of the retaining member 204 and the mounting portion, and each drainage gap is connected to the corresponding drainage channel 2013 (the drainage channel 2013 on the mounting top plate 20113). This prevents water accumulation at the retaining member 204, thus ensuring the overall drainage performance of the longitudinal beam 200.

[0096] In specific implementation, the fastening assembly of this embodiment includes bolts passing through the stop member 204 and the support portion 2012, and nuts screwed into the bolts. Specifically, in conjunction with... Figures 10 to 12 As shown, the blocking member 204 is provided with an adapter groove 2042 that is adapted to the support part 2012. The adapter groove 2042 is located in the middle of the blocking member 204 along the width direction of the longitudinal beam 200, so that the blocking member 204 and the support part 2012 can be inserted and matched. At the same time, the blocking part of the blocking member 204 located on both sides of the adapter groove 2042 can block the photovoltaic modules 300 in the mounting grooves 203 on each side of the grid.

[0097] Furthermore, the retaining member 204 is provided with a through hole 2043 arranged along the width direction of the longitudinal beam 200. The through hole 2043 is connected to the adapter groove 2042. The two second side plates 20121 in the support part 2012 are provided with side plate through holes corresponding to the through hole 2043, so that the bolt can be inserted into the through hole 2043 and screwed into the nut, thereby realizing the connection between the support part 2012 and the retaining member 204.

[0098] In addition, the bottom of the baffle 204 is provided with a groove 2041 so that the bottom of the baffle 204 has legs on both sides along the width direction of the longitudinal beam 200. After the baffle 204 is assembled with the support 2012, each leg is supported on the mounting top plate 20113. Based on the setting of the groove 2041, the above-mentioned drainage gap can be formed between the baffle 204, each leg and the mounting top plate 20113, thereby avoiding water accumulation at the baffle 204 and ensuring the overall drainage performance of the longitudinal beam 200.

[0099] The photovoltaic roof of this embodiment, by adopting the above-mentioned frame components, facilitates the convenient assembly and disassembly of two adjacent photovoltaic tiles 301, and helps to ensure the sealing between them, improves the wind resistance and waterproof performance of the photovoltaic tiles 301, reduces the risk of rainwater backflow, thereby improving the daily use effect of the photovoltaic tiles 301, and facilitating their later maintenance and replacement.
