Description

Technical Field

[0001] This invention relates to the field of photovoltaic power generation, and more specifically, to a photovoltaic module installation structure and a photovoltaic power generation system. Background Technology

[0002] BAPV (Building Attached Photovoltaic) refers to a distributed photovoltaic (PV) power generation system that installs photovoltaic modules on existing buildings. In recent years, the cost of PV products has been continuously decreasing. This type of distributed PV power generation can effectively utilize residential rooftop space, generating clean energy while also providing residents with stable electricity revenue. Therefore, residential distributed PV systems have developed rapidly.

[0003] Currently, many small tile roofs still exist in rural areas of my country. Typically, a small tile roof structure includes a roof board and small tiles. The roof board is covered with two layers of small tiles, either upturned or overhanging. Because the roof board has multiple small tiles, it occupies the installation space of the traditional BAPV (Building Aerated Concrete) support structure. During installation, some small tiles need to be removed, which not only increases the installation difficulty but also affects the roof's waterproofing performance, making traditional BAPV support structures difficult to adapt to small tile roofs. Summary of the Invention

[0004] This invention aims to at least solve the problem that traditional BAPV support mechanisms are difficult to adapt to small tile roofs in related technologies, and proposes a photovoltaic module installation structure and a photovoltaic power generation system.

[0008] In some embodiments, the vibration damping member includes two symmetrically arranged elastic abutment portions, which are respectively arranged in correspondence with the two first support plates, and the two elastic abutment portions abut against the corresponding first support plates.

[0009] In some embodiments, the support assembly includes: a support beam connected to the support portion; a support component disposed on the support beam for supporting the photovoltaic module; and a drainage component connected to the support component, the drainage component being located between the photovoltaic module and the support beam to collect and drain rainwater seeping from the edge of the photovoltaic module.

[0010] In some embodiments, the support assembly includes: a support member connected to the support beam, the support member having a support protrusion; a clamping portion disposed outside the support protrusion and forming a clamping space between the support protrusion and the support protrusion for clamping the drainage assembly; and a pressure block fixedly connected to the clamping portion and forming an installation space between the clamping portion and the clamping portion for installing the photovoltaic assembly.

[0011] In some embodiments, the drainage assembly includes: a first collecting trough whose length direction intersects the length direction of the support beam; a first groove is provided on the outer bottom surface of the first collecting trough; a first protrusion corresponding to the first groove is provided on the inner bottom surface of the first collecting trough; the support protrusion is located in the first groove; and the clamping part is clamped on the first protrusion.

[0014] According to a second aspect of the present invention, a photovoltaic power generation system is also disclosed, comprising: the photovoltaic module mounting structure described above.

[0015] The photovoltaic module installation structure of the present invention, since the support part is located between two roof tiles, does not affect the installation of the roof tiles. Furthermore, since the support part is provided with a receiving space for accommodating the cladding tiles, the cladding tiles can be placed in the receiving space. Compared with related technologies, the installation position of the cladding tiles is preserved, which can ensure the integrity of the fit between the cladding tiles and the roof tiles, thereby effectively avoiding water leakage problems caused by the removal of small tiles.

[0045] To enable those skilled in the art to better understand the technical solution of the present invention, the photovoltaic module installation structure and photovoltaic power generation system provided by the present invention will be described in detail below with reference to the accompanying drawings.

[0046] Currently, many small tiled roofs still exist in rural areas of my country. Typically, such as... Figure 1 As shown, the small tile roof structure includes: a sheath 1 and small tiles set on the sheath 1. The small tiles cover two layers of small tiles in two ways: upside down and downside down. The upside-down small tiles have their openings facing upwards and are also called upside-down tiles 2. The downside-down small tiles have their openings facing downwards and are also called downside-down tiles 3.

[0047] Because multiple small tiles are installed on roof slab 1, it occupies the installation space of the traditional BAPV support mechanism. During installation, if... Figure 2As shown, the support member 4 needs to be placed between two inverted tiles 2. Therefore, the corresponding retaining tile 3 needs to be moved to one side, exposing the gap between the two inverted tiles 2 that were originally located below the retaining tile 3, and the support member 4 is placed in the gap. This installation method not only increases the installation difficulty, but also affects the waterproof performance of the roof because the gap between the inverted tiles 2 is exposed, allowing rainwater to enter the house through the gap, causing leaks. Therefore, traditional BAPV support mechanisms are difficult to adapt to small tile roofs.

[0048] To solve the above technical problems, such as Figures 3 to 20 As shown, this invention discloses a photovoltaic module mounting structure, which is applicable to various mounting surfaces, such as the roof structure or ground of industrial plants or residential buildings. The roof structure can be a tiled roof 100 or a non-tiled roof, and no limitation is made in this embodiment. Among them, the photovoltaic module mounting structure of this invention is more suitable for tiled roofs 100.

[0049] The photovoltaic module installation structure of the present invention will be described below using a small tile roof 100 as an example.

[0050] like Figure 3 As shown, the photovoltaic module installation structure includes: a bracket assembly and a base 10 for installing the photovoltaic module. The base 10 is used to connect to the small tile roof 100. The bracket assembly is connected to the base 10. There are multiple bases 10 distributed at intervals. All multiple bases 10 are connected to the bracket assembly. The bracket assembly is connected to the small tile roof 100 through the base 10. The photovoltaic module is connected to the bracket assembly, thereby realizing the connection and fixation with the small tile roof 100.

[0051] like Figure 3 and Figure 4 As shown, the base 10 includes a connecting plate 11 and a support portion 12. The connecting plate 11 is used to connect to the small tile roof 100; the support portion 12 is used to be disposed between two adjacent roof tiles 120, the support portion 12 is connected to the connecting plate 11, the support portion 12 is used to support the bracket assembly, and the support portion 12 has a receiving space for accommodating the buckle tile 130.

[0052] In use, the connecting plate 11 can be fixedly connected to the sheathing plate 110 of the small tile roof 100. The support part 12 is also set between two adjacent roof tiles 120 and fixedly connected to the connecting plate 11. Since the support part 12 is provided with a receiving space, the buckle tile 130 can be set in the receiving space so that the buckle tile 130 can still be located above the gap between the two roof tiles 120. In other words, the buckle tile 130 can continue to maintain the position of covering the gap between the two roof tiles 120.

[0053] The photovoltaic module installation structure of the present invention, since the support part 12 is located between two roof tiles 120, does not affect the installation of the roof tiles 120. Furthermore, since the support part 12 is provided with a receiving space for accommodating the wall tile 130, the wall tile 130 can be placed in the receiving space. Compared with related technologies, the installation position of the wall tile 130 is preserved, which can ensure the integrity of the fit between the wall tile 130 and the roof tile 120, thereby preventing rainwater or snow water from entering the gap and effectively avoiding water leakage problems caused by the removal of the wall tile.

[0054] For ease of description, in this embodiment, a first direction (x-axis direction), a second direction (y-axis direction), and a third direction (z-axis direction) are introduced, and the first direction, the second direction, and the third direction are all perpendicular to each other. Among them, the first direction is the direction perpendicular to the roof slab 110, and the second direction is the extension direction of the roof ridge.

[0055] In such Figure 4 In the illustrated embodiment, the connecting plate 11 is rectangular, with its length direction along a third direction and its width direction along a second direction. Multiple through mounting holes 111 are provided on the connecting plate 11 along a first direction. These mounting holes 111 are used to install expansion bolts or ground nails, thereby achieving a fixed connection between the connecting plate 11 and the sheathing 110. It should be noted that while the connecting plate 11 is rectangular in this embodiment, this is not limiting. In some other embodiments not shown in the figures, the connecting plate 11 can also be square, circular, X-shaped, etc., and this is not a limitation in the embodiments of the present invention.

[0056] When the connecting plate 11 is rectangular, although the length direction of the connecting plate 11 is set along the third direction and the width direction is set along the second direction, this is not limiting. In some other embodiments not shown in the figure, the length direction of the connecting plate 11 may also be along the second direction and the width direction may be along the third direction. When the connecting plate 11 is a square, circle, X-shaped or other shapes, it is sufficient to fit with the sheath 110 so that the connecting plate 11 and the sheath 110 can be connected and fixed.

[0057] When the connecting plate 11 is used Figure 4 In the arrangement shown, the direction of the connecting plate 11 is perpendicular to the orthographic projection direction of the support beam 30 on the connecting plate 11. Therefore, the tilting of the support beam 30 can be prevented, thereby improving the reliability of the support.

[0058] like Figure 4As shown, the connecting plate 11 has multiple sets of mounting holes 111, with each set containing multiple mounting holes 111 spaced apart along the second direction. Different sets of mounting holes 111 are spaced apart along the third direction. This arrangement ensures uniform stress distribution on the surface of the connecting plate 11, thereby improving the reliability of the connection. In this embodiment, there are a total of four sets of mounting holes 111, with two mounting holes in each set. In some other embodiments not shown in the figure, the mounting holes 111 can be in two, three, or five sets, etc., and each set of mounting holes 111 can contain one, three, or four holes, etc., without limitation in this invention.

[0059] In this embodiment, the mounting hole 111 has an oblong shape to allow for fine-tuning of the placement of connectors such as expansion screws and ground stakes. Figure 4 As shown, the mounting hole 111 is provided along the length direction of the connecting plate 11. In other embodiments, the mounting hole 111 may also be provided along the width direction of the connecting plate 11.

[0060] like Figure 3 and Figure 4 As shown, the support portion 12 includes a support arm 121, a damping member 122, and an adjusting arm 123. The support arm 121 is arranged along a first direction and has a first end and a second end in that direction. The first end of the support arm 121 is connected to the connecting plate 11. The adjusting arm 123 is adjustablely connected to the second end of the support arm 121 and is connected to the bracket assembly, thereby supporting the bracket assembly. There are two support arms 121, spaced apart along a second direction, forming a receiving space between them. There are also two adjusting arms 123, each corresponding to a support arm 121 and adjustablely connected to the second end of the corresponding support arm 121. The damping member 122 is connected between the two support arms 121 and located between the receiving space and the connecting plate 11.

[0061] By setting two support arms 121 and forming a receiving space through the support arms 121, the tile 130 can be placed in the receiving space, and the tile 130 can still be located above the gap between the corresponding two roof tiles 120, thereby covering the gap and preventing rainwater from entering.

[0062] By setting up the adjusting arm 123, it has a fixed state and an adjusting state during use. In the fixed state, the adjusting arm 123 is fixedly connected to the corresponding support arm 121; in the adjusting state, the adjusting arm 123 is movably connected to the corresponding support arm 121 to adjust the distance between the support assembly and the small tile roof 100. By setting up the adjusting arm 123, the distance between the support assembly and the small tile roof 100, that is, the distance between the support assembly and the roof panel 110 in the first direction, can be adjusted. This allows the position of the support assembly to be adjusted as needed during assembly, improving assembly quality.

[0063] like Figure 4 As shown, the support arm 121 includes: a first support plate 1211, a second support plate 1212, and a third support plate 1213. The first support plate 1211 is arranged along a first direction, and its first end is connected to the connecting plate 11. The first support plates 1211 of the two support arms 121 are spaced apart in a second direction, and a damping member 122 is connected between the two first support plates 1211. The second support plate 1212 is arranged along a second direction, and its first end is connected to the second end of the first support plate 1211. The second ends of the second support plates 1212 of the two support arms 121 are far apart from each other. The third support plate 1213 is arranged along the first direction, and its first end is connected to the second end of the second support plate 1212. The second ends of the third support plates 1213 of the two support arms 121 are connected to the corresponding adjusting arms 123. A receiving space is formed between the second support plates 1212 and the third support plate 1213 of the two support arms 121.

[0064] It is understood that in this embodiment, the first support plate 1211 and the third support plate 1213 are both arranged along the first direction, while the second support plate 1212 is arranged along the second direction. In other words, the arrangement direction of the second support plate 1212 intersects with the arrangement direction of the first support plate 1211 and the arrangement direction of the third support plate 1213, thereby forming an accommodating space between the second support plate 1212 and the third support plate 1213 of the two support arms 121.

[0065] In this embodiment, as Figure 4 As shown, the included angles between the second support plate 1212 and the first support plate 1211, and between the second support plate 1212 and the third support plate 1213, are both acute angles. Using this method, as... Figure 3 As shown, by placing the buckle tile 130 in the receiving space, the two ends of the buckle tile 130 can be lower than the two ends of the inverted tile 120, thereby improving the blocking effect on the gap between the inverted tiles 120.

[0066] In this embodiment, the spacing between the two third support plates 1213 can be set according to the size of the tile 130, so that the third support plates 1213 can apply a certain clamping force to the tile 130, thereby ensuring that the tile 130 can be fixed in the receiving space and preventing the tile 130 from falling off. Furthermore, the second support plate 1212 and the third support plate 1213 are set at an acute angle, so that the second support plate 1212 and the third support plate 1213 can clamp the two ends of the tile 130 to a certain extent, which is more conducive to fixing the tile 130.

[0067] It should be noted that, although in this embodiment, the included angles between the second support plate 1212 and the first support plate 1211, and between the second support plate 1212 and the third support plate 1213 are both acute angles, this is not limiting. In some other embodiments not shown in the figures, the included angles between the second support plate 1212 and the first support plate 1211, and between the second support plate 1212 and the third support plate 1213, can also be right angles or obtuse angles, and are not limited in the embodiments of the present invention.

[0068] For example, such as Figure 4 As shown, a first waist-shaped hole 91 is provided on the first support plate 1211. The length direction of the first waist-shaped hole 91 is set along the first direction. The vibration damper 122 is connected to the first waist-shaped hole 91 by bolts and nuts, thereby realizing the adjustment of the installation position of the vibration damper 122 in the vertical direction.

[0069] For example, such as Figure 4 As shown, in this embodiment, a second oblong hole 92 is provided on both the third support plate 1213 and the adjusting arm 123. The second oblong hole 92 is arranged along the first direction, and the third support plate 1213 and the adjusting arm 123 are connected to the corresponding adjusting arm 123 through the second oblong hole 92 and the bolt and nut. When it is necessary to adjust the position of the adjusting arm 123, the nut can be loosened, so that the bolt can move along the length of the second oblong hole 92, thereby realizing the movable connection between the support arm 121 and the adjusting arm 123. After the adjustment is completed, the bolt can be tightened, thereby realizing the fixed connection between the support arm 121 and the adjusting arm 123.

[0070] It should be noted that in this embodiment, a second oblong hole 92 is provided on both the third support plate 1213 and the adjusting arm 123. However, this is not limiting. In some other embodiments not shown in the figure, the second oblong hole 92 may be provided only on the adjusting arm 123, while the third support plate 1213 may be a round hole. Conversely, it is feasible to provide a second oblong hole 92 on the third support plate 1213 and a round hole on the corresponding adjusting arm 123. This is not a limitation in the embodiments of the present invention.

[0071] Furthermore, the number of second oblong holes 92 can be one, two, or three, etc., and multiple second oblong holes 92 can be spaced apart along the first direction or spaced apart along a third direction. For example, in this embodiment, there are two second oblong holes 92 and they are spaced apart along the first direction.

[0072] For example, the first support plate 1211, the second support plate 1212 and the third support plate 1213 are integrally formed structures.

[0073] like Figure 3 As shown, the photovoltaic module installation structure also includes a diversion channel 20, which is arranged along a third direction to divert a portion of the rainwater. Figure 4 As shown, the adjusting arm 123 includes a fourth support plate 1231, a fifth support plate 1232, and a support flange 1233. The fourth support plate 1231 is arranged along a first direction and is connected to the corresponding support arm 121; the fifth support plate 1232 is arranged along a second direction and is connected to the fourth support plate 1231, and is connected to the bracket assembly. The fifth support plates 1232 of the two adjusting arms 123 are located between the two fourth support plates 1231. The support flange 1233 is disposed at the end of the fifth support plate 1232 away from the fourth support plate 1231, and a support space for supporting the diversion channel 20 is formed between the two support flanges 1233. By setting the support flange 1233, a support space can be formed between the two support flanges 1233, thereby achieving support for the diversion channel 20. In other words, the support part 12 in this embodiment can not only accommodate the tile 130 and maintain the integrity of the small tile structure, but also support the diversion channel 20, which is a typical example of a single item serving multiple purposes.

[0074] For example, a second oblong hole 92 may be provided on the fourth support plate 1231. A third oblong hole 93 is provided on the fifth support plate 1232, and the direction of the third oblong hole 93 is set along the second direction, thereby realizing the position adjustment between the bracket assembly and the base 10 in the second direction.

[0075] Furthermore, the number of third oblong holes 93 can be one, two, or three, etc., and multiple third oblong holes 93 can be spaced apart along the second direction or spaced apart along the third direction. For example, in this embodiment, there is one third oblong hole 93.

[0076] For example, the fourth support plate 1231 and the fifth support plate 1232 are integrally formed structures.

[0077] It should be noted that, in this embodiment, the connection plate 11 and the support arm 121 can be connected by integral molding or by a detachable method, such as welding or bolt connection.

[0078] It should also be noted that, in cases such as Figure 4 In the illustrated embodiment, the support portion 12 includes a support arm 121, a damping member 122, and an adjusting arm 123, with the support arm 121 and the adjusting arm 123 being adjustablely connected. However, this is not limiting. In some other embodiments not shown, the support arm 121 and the adjusting arm 123 may be non-adjustable, such as by welding or by being integrally stamped. In other embodiments, the support portion 12 may not include the adjusting arm 123. When the support arm 121 does not include the adjusting arm 123, the support arm 121 can be directly connected to the bracket assembly to support the bracket assembly.

[0079] In this embodiment, by setting up the vibration damping component 122, the vibration of the two support arms 121 can be reduced when they vibrate, thereby reducing the fatigue damage to the bottom fixing component and the original house structure caused by vibration. At the same time, the vibration displacement of the tile surface can be reduced, which greatly improves the structural safety and maintains the density and integrity of the original tile.

[0080] Specifically, such as Figure 5 As shown, the damping member 122 includes two symmetrically arranged elastic abutment portions 1221, which are arranged one-to-one with two first support plates 1211, and the two elastic abutment portions 1221 abut against the corresponding first support plates 1211 respectively.

[0081] For example, the elastic abutment portion 1221 is a bridge-shaped semi-elliptical spherical structure with a central hollow core. The tops of the two elastic abutment portions 1221 are connected, and the open ends of the two elastic abutment portions 1221 face the two first support plates 1211 respectively. The open ends of the two elastic abutment portions 1221 abut against the corresponding first support plates 1211. A first through hole 1222 is provided at the top position of the elastic abutment portion 1221. The first through holes 1222 on the two elastic abutment portions 1221 are connected, and the first waist-shaped holes 91 on the two first support plates 1211 correspond to the first through holes 1222. Bolts are inserted into the two first waist-shaped holes 91 and the first through holes 1222 and fixed with nuts, thereby realizing the fixed connection between the vibration damper 122 and the two first support plates 1211.

[0082] In use, as the nuts are tightened, the two first support plates 1211 approach each other and press against the two elastic abutment parts 1221, causing the two elastic abutment parts 1221 to deform. The elastic abutment parts 1221 are made of polymer material, which has the properties of energy absorption and elasticity and can reduce vibration frequency. After the internal pressure deformation under the action of external force, it generates rebound tension on the two first support plates 1211, so that the two support arms 121 are in an internal and external tension balance state. When the two support arms 121 are in this balance state, under the action of strong wind, the elastic abutment parts 1221 can effectively reduce high-frequency wind vibration, thereby reducing fatigue damage to the connectors and the small tile roof 100 structure itself caused by vibration. At the same time, it can reduce the vibration displacement of the upright tile 120 and the buckle tile 130, which greatly improves the structural safety and maintains the density and integrity of the original small tile structure.

[0083] In some embodiments, the support assembly includes: a support beam 30 (see...) Figure 3 ), support components and drainage components 40 (see Figure 6 Each support beam 30 is arranged along the second direction, and multiple support beams 30 are distributed at intervals in the third direction. Each support beam 30 is connected to the support part 12 of multiple bases 10, thereby achieving a fixed connection with the roof board 110 of the small tile roof 100.

[0084] In this embodiment, all bases 10 are divided into multiple groups, with each group of bases 10 connected to the same support beam 30. Therefore, the bases 10 in the same group are spaced apart in the second direction. The bases 10 in different groups are spaced apart in the third direction, and there is a one-to-one correspondence between the bases 10 in different groups. In other words, in the third direction, the corresponding bases 10 in different groups are located on the same straight line, so that the support spaces on each corresponding base 10 are on the same straight line. This allows the diversion channel 20 extending along the third direction to be simultaneously arranged in multiple support spaces.

[0085] For example, please refer to Figure 3 and Figure 4 As shown, the fifth support plate 1232 in each base 10 abuts against the bottom surface of the support beam 30 and is fixedly connected to the support beam 30 by bolts. By setting the support flange 1233, the support space is located below the support beam 30, thereby avoiding mutual interference between the diversion channel 20 and the support beam 30.

[0086] Support components are mounted on support beams 30 to support photovoltaic modules. In other words, the photovoltaic modules are installed on the support components, which connect them to the support beams 30 for fixation. Drainage components 40 are connected to the support components and located between the photovoltaic modules and the support beams 30 to collect and drain rainwater seeping from the edges of the photovoltaic modules. Because multiple photovoltaic modules need to be assembled, gaps exist between adjacent modules, allowing rainwater to seep into the roof tiles and potentially cause leaks. The drainage components 40 effectively drain this seepage, preventing leaks. The support components not only fix the photovoltaic modules but also the drainage components 40, serving multiple purposes. Connecting the drainage components 40 to the support components allows for fixation of the drainage components 40, eliminating the need for a separate support structure and simplifying the photovoltaic installation structure, thus reducing material and installation costs.

[0087] Specifically, the support assembly includes: a support member, a clamping part, and a pressure block. The support member is connected to the support beam 30 and is provided with a support protrusion; the clamping part is located outside the support protrusion and forms a clamping space between the support protrusion and the support protrusion for clamping the drainage assembly 40; the pressure block is fixedly connected to the clamping part and forms an installation space between the clamping part for installing the photovoltaic module.

[0088] In use, support protrusions are provided on the support member, which cooperate with the clamping part to form a clamping space, thereby clamping the drainage component 40 within the clamping space and achieving relative fixation between the drainage component 40, the support beam 30, and the photovoltaic module. Compared with the connection method of bolting the drainage component 40 in related technologies, the clamping method of the support member to fix the drainage component 40 avoids perforation of the drainage component 40, thus ensuring the integrity of the drainage component 40 and preventing water leakage at perforation points. Moreover, the clamping fixation method from top to bottom results in a more even clamping force on the drainage component 40, with less stress concentration and lower strength requirements for the drainage component 40. Therefore, the thickness of the drainage component 40 can be reduced, which increases the firmness of the node installation while saving material costs and weight of the drainage component 40.

[0089] like Figure 6 As shown, in this embodiment, the support assembly has a first region and a second region arranged adjacent to each other. In the first region, the length direction of all photovoltaic modules is arranged along a third direction, in other words, the photovoltaic modules in the first region are installed vertically; in the second region, the length direction of all photovoltaic modules is arranged along a second direction, in other words, the photovoltaic modules in the second region are installed horizontally.

[0090] Accordingly, the support components include: a plurality of first support components 50 and a plurality of second support components 60. The plurality of first support components 50 are disposed in a first region to support photovoltaic modules located in the first region; the plurality of second support components 60 are disposed in a second region to support photovoltaic modules located in the second region.

[0091] In this embodiment, a mixed horizontal and vertical mounting structure for photovoltaic modules can be achieved by setting up a support assembly. However, for this mixed horizontal and vertical mounting structure, the arrangement of the photovoltaic modules is more complex than that of a purely vertical installation structure, leading to a more complex installation method for the drainage assembly 40, and potential conflicts between its components. By employing the first support assembly 50 and the second support assembly 60, the installation of the drainage assembly 40 can be accommodated while simultaneously achieving the mixed horizontal and vertical mounting of the photovoltaic modules, avoiding conflicts between the drainage components 40.

[0092] like Figure 6 As shown, the drainage assembly 40 includes a first collecting trough 41, a second collecting trough 42, and a drainage trough 46. The length direction of the first collecting trough 41 is arranged along a third direction, the length direction of the second collecting trough 42 is arranged along a second direction, and the length direction of the drainage trough 46 is also arranged along the second direction.

[0093] Multiple first collecting channels 41 are arranged in a first region, each first collecting channel 41 being arranged along a third direction; in other words, the length direction of the first collecting channel 41 intersects the length direction of the support beam 30. The multiple first collecting channels 41 are distributed at intervals along a second direction, each first collecting channel 41 corresponding to at least one vertically installed photovoltaic module in the first region and located below the long edge of the corresponding photovoltaic module to collect rainwater seeping from the long edge of the corresponding photovoltaic module. Each first collecting channel 41 is connected to multiple first support components 50 in a third direction.

[0094] Specifically, such as Figure 7 As shown, the first support assembly 50 includes: a first support member 51, a first clamping part 52, and a first pressing block 53. The first support member 51 is connected to the support beam 30, and the first support member 51 is provided with a first support protrusion 511; the first clamping part 52 is provided on the outside of the first support protrusion 511 and forms a clamping space for clamping the drainage assembly 40 between the first support protrusion 511 and the first pressing block 53 is fixedly connected to the first clamping part 52 and forms an installation space for installing the photovoltaic module between the first clamping part 52 and the first clamping part 52.

[0095] like Figure 8As shown, a first groove 411 is provided on the outer bottom surface of the first collecting groove 41, and a first protrusion 412 corresponding to the first groove 411 is provided on the inner bottom surface of the first collecting groove 411. A first supporting protrusion 511 is located inside the first groove 411, and a first clamping part 52 is clamped on the first protrusion 412. In other words, the first protrusion 412 is formed by the groove bottom of the first collecting groove 41 recessed from the outside to the inside. By providing the first protrusion 412 and the first groove 411, the first supporting protrusion 511 can be accommodated by the first groove 411, and the first protrusion 412 is clamped and engaged by the first clamping part 52, thereby achieving fixation with the first support assembly 50. Since the contact between the first supporting protrusion 511 and the first groove 411, and between the first clamping part 52 and the first protrusion 412, is surface-to-surface during the clamping process, stress concentration can be reduced, ensuring connection reliability while reducing the risk of deformation of the first collecting groove 41.

[0096] In this embodiment, as Figure 9 As shown, the first support member 51 further includes two mounting slots 512, spaced apart along the length of the support beam 30. In other words, the two mounting slots 512 are spaced apart in the second direction, and each mounting slot 512 is itself arranged along the third direction. The first support protrusion 511 is located between and connected to the two mounting slots 512. The outer bottom surfaces of the two mounting slots 512 abut against the support beam 30 and are fixedly connected to the support beam 30. By setting the structure of the mounting slots 512, the outer bottom surfaces of the mounting slots 512 abut against the support beam 30, thereby achieving stable support for the first current collector 41, the first clamping part 52, and the first pressure block 53, and thus achieving stable support for the photovoltaic module. Furthermore, by using two mounting slots 512 spaced apart in the second direction, a double support position is formed in the second direction, thereby improving the stability and reliability of the support.

[0097] exist Figure 9 In the illustrated embodiment, the first support protrusion 511 has a first end and a second end in a first direction. The interior of the first support protrusion 511 has a first channel 5111 and a second channel 5112 arranged along a third direction. The first channel 5111 is located at the first end of the first support protrusion 511, and the second channel 5112 is located at the second end of the first support protrusion 511. A first clamping part 52 clamps the first end of the first support protrusion 511, and the second end of the first support protrusion 511 is connected to the sidewall of the mounting groove 512. The width of the first channel 5111 in the second direction is greater than the width of the second channel 5112 in the second direction, forming a first step structure 513 between the first end and the second end of the first support protrusion 511. In other words, a first step structure 513 is formed at the connection point between the first channel 5111 and the second channel 5112.

[0098] Please combine Figure 7 and Figure 8 As shown, the structure of the first groove 411 in the first collecting groove 41 matches the structure of the first support protrusion 511. Therefore, a second step structure 413 matching the first step structure 513 is also formed on the first protrusion 412. When the first support protrusion 511 is located in the first groove 411, the first support protrusion 511 forms a limiting fit in the first direction with the inner side of the first step structure 513 and the second step structure 413, thereby preventing the first collecting groove 41 and the first support member 51 from separating in the first direction, thus improving the reliability and stability of their connection.

[0099] Correspondingly, when the first clamping part 52 and the first protrusion 412 are clamped together, the first clamping part 52 and the first protrusion 412 achieve a limiting engagement in the first direction through the outer side of the second step structure 413, so as to prevent the first clamping part 52 and the first protrusion 412 from separating from each other in the first direction after clamping, thereby improving the reliability and stability of the connection between the two.

[0100] It is understandable that when assembling the first collection channel 41 and the first support member 51, the first support protrusion 511 of the first support member 51 can be installed into the first groove 411 from one end of the length direction of the first collection channel 41. Then, the first support member 51 can be moved to a preset position by the relative sliding of the two, thereby realizing the subsequent assembly.

[0101] There can be various connection methods between the first support member 51 and the support beam 30. For example, the first support member 51 is provided with bolts, which are directly connected to the support beam 30, or the bolts are connected to the support beam 30 through nuts and / or connecting blocks.

[0102] In this embodiment, as Figure 7 and Figure 8 As shown, the support beam 30 is a concave beam with a connecting pressure block 31 embedded inside. Bolts are inserted into the first support member 51 and the connecting pressure block 31 to achieve a fixed connection between the first support member 51 and the support beam 30.

[0103] like Figure 9 As shown, in this embodiment, the two mounting grooves 512 of the first support member 51 and the first end of the first support protrusion 511 are all provided with second through holes 515 for mounting bolts, so as to achieve a stable and reliable connection with the connecting pressure block 31.

[0104] For example, the first support protrusion 511 is provided with a first relief groove 514, and the second through hole 515 is provided in the first relief groove 514 to accommodate the nut of the bolt.

[0105] For example, the first support member 51 is integrally formed, such as by stamping sheet metal.

[0106] like Figure 7 , Figure 10 and Figure 11 As shown, the first clamping part 52 includes a first support block 521 and two first clamping members 522. The first support block 521 is connected to the first pressure block 53 and forms an installation space. For example, the first support block 521 is provided with a screw hole, and the first pressure block 53 is provided with a third through hole 531 for installing bolts. The bolt passes through the third through hole 531 and is connected to the screw hole of the first support block 521.

[0107] exist Figure 7 In the illustrated embodiment, the length direction of the first support block 521 of the first clamping portion 52 is arranged along a third direction, such as... Figure 10 As shown, first side plates 5211 are respectively provided on both sides of the width direction of the first support block 521 to support the photovoltaic module. Figure 12 As shown, the first pressure block 53 is provided with a first pressure plate 532 corresponding to the first side plate 5211. When the first support block 521 is connected to the first pressure block 53, the first side plate 5211 and the first pressure plate 532 form an installation space, thereby clamping and fixing the photovoltaic module in the installation space.

[0108] like Figure 11 As shown, the two first clamping members 522 are detachably connected to the first support block 521 to facilitate installation and removal from the first collection channel 41. The two first clamping members 522 are spaced apart along a second direction, and a first support protrusion 511 is located between the two first clamping members 522, forming a clamping space between them. In other words, the two first clamping members 522 are symmetrically arranged on both sides of the width direction of the first support block 521. For example, the two first clamping members 522 and the first support block 521 are detachably connected by bolts.

[0109] like Figure 11 As shown, the first clamping member 522 is provided with a first mating groove 5221 for engaging with the first support protrusion 511. During assembly, the two first clamping members 522 are fixedly connected to the first support block 521 by bolts. The first clamping member 522 forms a clamping engagement with the first protrusion 412 on the first collection channel 41. The first mating groove 5221 can achieve a limiting engagement with the outer side of the second step structure 413 in the first direction, thereby preventing the first clamping member 522 from disengaging from the first collection channel 41 in the first direction and improving the stability and reliability of the connection.

[0110] like Figure 6As shown, there are multiple second flow collection channels 42, located at the boundary between the first and second regions. The length direction of each second flow collection channel 42 is along the second direction; in other words, the length direction of the second flow collection channel 42 is the same as the length direction of the support beam 30. The multiple second flow collection channels 42 are also spaced apart along the second direction, such as... Figure 13 As shown, at the junction of the first and second areas, the vertically installed photovoltaic modules located at the inner edge of the first area are adjacent to the horizontally installed photovoltaic modules located at the inner edge of the second area, and a gap is formed between them. In rainy or snowy weather, rainwater or snow water can easily seep into the small tile roof 100 through this gap, leading to the risk of water leakage.

[0111] In this embodiment, each second collection channel 42 is located below the boundary between the first and second regions, thereby collecting rainwater or snowmelt seeping in from the gap at that location, thus preventing the small tile roof 100 from leaking.

[0112] It is understandable that the width of the second manifold 42 in the third direction is greater than the width of the gap; in other words, as... Figure 13 As shown, the orthographic projection of the short side of the vertically installed photovoltaic module in the first region in the first direction is located inside the second collector trough 42. Similarly, the orthographic projection of the long side of the horizontally installed photovoltaic module in the second region is also located inside the second collector trough 42. Therefore, the second collector trough 42 can collect rainwater that seeps in from the edge of the long side of the corresponding photovoltaic module. Each second collector trough 42 is connected to multiple second support components 60 in the second direction.

[0113] Specifically, such as Figure 13 As shown, the second support assembly 60 includes: a second support member 61, a second clamping part 62, and a second pressure block 63. The second support member 61 is connected to the support beam 30, and the second support member 61 is provided with a second support protrusion 611 (see...). Figure 15 The second clamping part 62 is disposed on the outside of the second support protrusion 611 and forms a clamping space for clamping the drainage component 40 between the second support protrusion 611; the second pressing block 63 is fixedly connected to the second clamping part 62 and forms an installation space for installing the photovoltaic module between the second clamping part 62.

[0114] like Figure 14 As shown, a second groove 421 is provided on the outer bottom surface of the second collection trough 42, and a second protrusion 422 corresponding to the second groove 421 is provided on the inner bottom surface of the second collection trough 42. In other words, as shown... Figure 14 As shown, the bottom of the second collection channel 42 is concave from the outside in, forming a second protrusion 422. After the second support assembly 60 is assembled with the second collection channel 42, please combine... Figures 13 to 15The second support protrusion 611 is located within the second groove 421, and the second clamping part 62 clamps onto the second protrusion 422. By providing the second protrusion 422 and the second groove 421, the second support protrusion 611 can be accommodated by the second groove 421, and the second protrusion 422 and the second clamping part 62 clamp together to achieve fixation with the second support assembly 60. Since the contact between the second support protrusion 611 and the second groove 421, and between the second clamping part 62 and the second protrusion 422, is surface-to-surface during the clamping process, stress concentration can be reduced, thus reducing the risk of deformation of the second collection groove 42 while ensuring connection reliability.

[0115] Since the length direction of the horizontally installed photovoltaic modules and the length direction of the second collector 42 in the second region are both set along the second direction, which is the setting direction of the support beam 30, the second support member 61 and the first support member 51 are slightly different in specific structure in order to better adapt to the horizontally installed photovoltaic modules and the second collector 42.

[0116] Specifically, such as Figure 15 As shown, the second support member 61 further includes two folded edges 612, disposed at the end of the second support protrusion 611 facing the support beam 30. The two folded edges 612 are spaced apart along the width direction of the support beam 30 and form a limiting groove. In other words, in this embodiment, the second support member 61 differs from the first support member 51 in that the second support member 61 is disposed along the second direction. Therefore, it cannot abut against the support beam 30 by setting the mounting groove 512 as the first support member 51. Thus, the mounting groove 512 will be located on the outside of the support beam 30 and cannot contact the support beam 30. However, by setting two folded edges 612 and spaced apart in the third direction, a limiting groove matching the support beam 30 is formed between the two folded edges 612. The bottom surface of the limiting groove abuts against the support beam 30, and the groove wall of the limiting groove forms a limiting fit with the support beam 30, thereby achieving reliable support and fixed connection between the second support member 61 and the support beam 30. This enables stable support for the second collector 42, the second clamping part 62, and the second pressing block 63, as well as stable support for the photovoltaic module.

[0117] exist Figure 15In the illustrated embodiment, the second support protrusion 611 also has a first end and a second end in the first direction. The interior of the second support protrusion 611 has a third channel 6111 and a fourth channel 6112 arranged along the second direction. The third channel 6111 is located at the first end of the second support protrusion 611, and the fourth channel 6112 is located at the second end of the second support protrusion 611. The second clamping part 62 clamps the first end of the second support protrusion 611. The second end of the second support protrusion 611 is connected to two folded edges 612. The width of the third channel 6111 in the third direction is greater than the width of the fourth channel 6112 in the third direction, forming a third step structure 613 between the first and second ends of the second support protrusion 611. In other words, a third step structure 613 is formed at the connection point of the third channel 6111 and the fourth channel 6112.

[0118] Please combine Figures 13 to 15 As shown, the second groove 421 in the second collection channel 42 (see Figure 14 The structure of the second support protrusion 611 (see) Figure 15 ) matches, therefore, as Figure 14 As shown, a fourth step structure 423 is also formed on the second protrusion 422, which is mutually restrictive with the third step structure 613. When the second support protrusion 611 is located in the second groove 421, the second support protrusion 611 forms a restrictive fit in the first direction through the inner side of the third step structure 613 and the fourth step structure 423, thereby preventing the second collection groove 42 and the second support member 61 from separating from each other in the first direction, thus improving the reliability and stability of their connection.

[0119] Correspondingly, such as Figures 13 to 16 As shown, when the second clamping part 62 and the second protrusion 422 (please refer to...) Figure 13 and Figure 14 When clamping, the second clamping part 62 and the second protrusion 422 achieve a limiting engagement in the first direction through the outer side of the fourth step structure 423, so as to prevent the second clamping part 62 and the second protrusion 422 from separating from each other in the first direction after clamping, thereby improving the reliability and stability of the connection between the two.

[0120] It is understandable that when assembling the second collection channel 42 and the second support member 61, the second support protrusion 611 of the second support member 61 can be installed into the second groove 421 from one end of the length direction of the second collection channel 42, and then the second support member 61 can be moved to a preset position by the relative sliding of the two, thereby realizing the subsequent assembly.

[0121] There can be various connection methods between the second support member 61 and the support beam 30. For example, the second support member 61 is provided with bolts, which are directly connected to the support beam 30, or the bolts are connected to the support beam 30 through nuts and / or connecting blocks 31.

[0122] In this embodiment, as Figure 13 As shown, bolts are inserted through the second support member 61 and the connecting pressure block 31, thereby achieving a fixed connection between the second support member 61 and the support beam 30.

[0123] like Figure 15 As shown, in this embodiment, at least one fourth through hole 615 for mounting bolts is provided on the second support protrusion 611 of the second support member 61, thereby enabling a stable and reliable connection with the connecting pressure block 31.

[0124] For example, the fourth through hole 615 can be one, two, three, etc., and when there are two or more fourth through holes 615, the multiple fourth through holes 615 are spaced apart along the length direction of the support beam 30, that is, the second direction, thereby improving the stability and reliability of the connection.

[0125] For example, the second support protrusion 611 is provided with a second relief groove 614, and the fourth through hole 615 is located in the second relief groove 614 to accommodate the nut of the bolt.

[0126] For example, the second support member 61 is integrally formed, such as by stamping sheet metal.

[0127] like Figure 16 As shown, the structure of the second clamping part 62 is basically the same as that of the first clamping part 52. Specifically, the second clamping part 62 includes: a second support block 621 and two second clamping members 622. Please refer to... Figure 13 and Figure 16 As shown, the second support block 621 is connected to the second pressure block 63 to form an installation space. For example, the second support block 621 is provided with screw holes, and the second pressure block 63 is provided with a fifth through hole 632 for mounting bolts (see [reference]). Figure 13 The bolt passes through the fifth through hole 632 and connects to the second support block 621 of the second clamping part 62 (see...). Figure 16 (inside the screw hole).

[0128] like Figure 16 As shown, the length of the second support block 621 is arranged along the second direction, and second side plates 6211 are respectively arranged on both sides of the width direction of the second support block 621, thereby achieving support for the photovoltaic module. Figure 13As shown, the second pressure block 63 is provided with a second pressure plate 631 corresponding to the second side plate 6211. When the second support block 621 is connected to the second pressure block 63, the second side plate 6211 and the second pressure plate 631 form an installation space, thereby clamping and fixing the photovoltaic module in the installation space.

[0129] Similarly, the two second clamping members 622 are detachably connected to the second support block 621 to facilitate installation and removal from the second collection channel 42. The two second clamping members 622 are spaced apart along a third direction, and the second support protrusion 611 is located between the two second clamping members 622, forming a clamping space between them. In other words, the two second clamping members 622 are symmetrically arranged on both sides of the second support block 621 in the width direction. For example, the two second clamping members 622 and the second support block 621 are detachably connected by bolts.

[0130] The second clamping member 622 is also provided with a second mating groove 6221 for engaging with the second support protrusion 611. During assembly, the two second clamping members 622 are fixedly connected to the second support block 621 by bolts. The second clamping member 622 and the second protrusion 422 on the second collection channel 42 form a clamping engagement. The second mating groove 6221 can achieve a limiting engagement with the outer side of the fourth step structure 423 in the first direction, thereby preventing the second clamping member 622 from disengaging from the second collection channel 42 in the first direction and improving the stability and reliability of the connection.

[0131] like Figure 17 As shown, the drainage channel 46 is located in the second area. The length direction of the drainage channel 46 is the same as that of the support beam 30; in other words, it is also arranged along the second direction. Therefore, it is also connected and fixed to the support beam 30 through multiple second support members 61. The drainage channel 46 is located at the end of the bracket assembly away from the ridge. In other words, the drainage channel 46 is installed on the support beam 30 that is farthest from the ridge among all the support beams 30, that is, the lowest support beam 30. Therefore, the drainage channel 46 is also located at the lowest position of the tiled roof 100, so that water can be collected by gravity and eventually drained.

[0132] like Figure 18 As shown, the outer bottom surface of the drainage groove 46 is provided with a third groove 461, and the inner bottom surface of the drainage groove 46 is provided with a third protrusion 462 corresponding to the third groove 461. The support protrusion is located in the third groove 461, and the second clamping part 62 is clamped on the third protrusion 462.

[0133] like Figure 18As shown, the drainage channel 46 includes: a first sub-channel 463 and a second sub-channel 464, a third protrusion 462 located between the first sub-channel 463 and the second sub-channel 464, the first sub-channel 463 located on the side of the third protrusion 462 away from the roof ridge, the depth of the first sub-channel 463 being greater than the depth of the second sub-channel 464, and a connection port for connecting to the diversion channel 20 provided on the first sub-channel 463.

[0134] like Figure 19 As shown, in this embodiment, the first sub-channel 463 is located on the side of the third protrusion 462 away from the roof ridge, while the second sub-channel 464 is located on the side of the third protrusion 462 facing the roof ridge. In other words, the first sub-channel 463 is located at a position lower than the second sub-channel 464. Furthermore, since the depth of the first sub-channel 463 is greater than the depth of the second sub-channel 464, the water capacity of the first sub-channel 463 is greater than that of the second sub-channel 464, thereby preventing excessive water accumulation and overflow in the first sub-channel 463.

[0135] It should be noted that the connection port is located on the side wall of the first sub-slot 463 near the ridge. Since the depth of the first sub-slot 463 is greater than the depth of the second sub-slot 464, the wall of the first sub-slot 463 has sufficient depth to accommodate the connection port, and the location of the connection port can avoid the second sub-slot 464, that is, it is located below the second sub-slot 464. Therefore, the diversion channel 20 can pass under the second sub-slot 464, and one end of the diversion channel 20 can be inserted into the connection port to achieve a sealed fit, thereby enabling the diversion channel 20 to communicate with the first sub-slot 463. The second sub-slot 464 can also have a drain hole set at a corresponding position above the diversion channel 20, so that the water inside can enter the corresponding diversion channel 20 through the drain hole, and finally converge into the first sub-slot 463 through the corresponding diversion channel 20.

[0136] like Figure 6 As shown, the drainage assembly 40 also includes: a third collection channel 43, a fourth collection channel 44, a fifth collection channel 45, and a cover plate 47.

[0137] Multiple third collecting channels 43 are arranged within the second area. Each third collecting channel 43 is arranged along a third direction and corresponds one-to-one with a first collecting channel 41. The third collecting channel 43 is located between the drainage channel 46 and the corresponding first collecting channel 41, with one end of the first collecting channel 41 overlapping the third collecting channel 43. In other words, the third collecting channel 43 is arranged along a third direction between the first collecting channel 41 and the drainage channel 46, and the water collected in the first collecting channel 41 is diverted to the drainage channel 46 through the third collecting channel 43. Specifically, one end of each third collecting channel 43 overlaps and is fixed to the first collecting channel 41, allowing water from the first collecting channel 41 to flow into the third collecting channel 43; while the other end of the third collecting channel 43 overlaps and is fixed to the second sub-channel 464 of the drainage channel 46, allowing water in the third collecting channel 43 to flow into the second sub-channel 464. For example, the first collection channel 41 and the third collection channel 43, and the third collection channel 43 and the drainage channel 46 can be fixed by self-tapping screws, or by other methods such as bonding, snap-fitting, welding, etc.

[0138] It is understood that multiple third collecting channels 43 are spaced apart in the second direction, while second collecting channels 42 are disposed between two adjacent third collecting channels 43. Furthermore, the two ends of each second collecting channel 42 overlap and are fixedly connected to the two adjacent third collecting channels 43, thereby allowing water in the second collecting channel 42 to flow into the third collecting channels 43 at both ends. For example, the second collecting channel 42 and the third collecting channel 43 can be fixed together using self-tapping screws, or by other methods such as adhesive bonding, snap-fitting, or welding.

[0139] The fourth collector 44 consists of multiple groups and is set in the first area. A group of fourth collector 44 is set between two adjacent first collector 41. Each group of fourth collector 44 consists of multiple groups and corresponds to the gap between two photovoltaic modules that are adjacent to each other in the third direction. The fourth collector 44 is connected to the corresponding diversion channel 20.

[0140] In other words, the fourth collector trough 44 is disposed in the first region along the second direction and corresponds to the gap between two adjacent photovoltaic modules in the first region in the third direction, thereby collecting rainwater or snowmelt seeping into the short side of the vertically installed photovoltaic modules in the first region. The two ends of the fourth collector trough 44 overlap with two adjacent first collector troughs 41, thereby collecting and diverting rainwater seeping into the first region from the gap corresponding to the short side of the photovoltaic modules into the first collector troughs 41. For example, the first collector troughs 41 and the fourth collector trough 44 can be fixed together by self-tapping screws, or by other methods such as bonding, snap-fitting, or welding.

[0141] like Figure 6 and Figure 20As shown, the cover plate 47 covers the ridge of the small tile roof 100 along the second direction, and the end of the first collecting channel 41 near the ridge is located below the cover plate 47. The cover plate 47 includes: a guide plate 471 and a limiting flange 472. The guide plate 471 can be determined according to the specific situation of the small tile roof 100. For example, if the small house roof is Figure 6 The double-sided structure shown has two guide plates 471 connected to each other in a "V" shape, which can cover the top of both sides of the small tile roof 100. The limiting flange 472 is set on the outside of the two guide plates 471 for limiting cooperation with the fifth collection channel 45. In some embodiments, if the small tile roof 100 is a single-sided structure, only one guide plate 471 can be provided, which is also feasible. This embodiment does not impose any restrictions.

[0142] Multiple fifth collecting channels 45 are arranged along the second direction at the edge of the first area. The fifth collecting channels 45 are positioned at the gap between the cover plate 47 and the photovoltaic module. One fifth collecting channel 45 is arranged between every two first collecting channels 41. The two ends of the fifth collecting channel 45 overlap with the adjacent first collecting channel 41. The cover plate 47 is used to guide rainwater to flow into the fifth collecting channel 45. The limiting flange 472 is located on the inner wall of the fifth collecting channel 45 and cooperates with the wall of the fifth collecting channel 45 to prevent the fifth collecting channel 45 from detaching from the cover plate 47. Moreover, the limiting flange 472 can also play a guiding role. Water on the guide plate 471 can enter the fifth collecting channel 45 along the limiting flange 472, thereby preventing rainwater or snow water from falling outside the fifth collecting channel 45.

[0143] For example, the fifth collection channel 45 and the first collection channel 41, and the third collection channel 43 and the drainage channel 46 can be fixed by self-tapping screws, or by other methods such as bonding, snap-fitting, welding, etc.

[0144] In addition, such as Figure 20 As shown, the short side of the photovoltaic module is located above the fifth collector trough 45, which can prevent rainwater from seeping in.

[0145] In this embodiment, there are multiple diversion channels 20, each arranged along a third direction, and the multiple diversion channels 20 are spaced apart along a second direction. Each diversion channel 20 is located between two adjacent first collection channels 41, with one end of each diversion channel 20 located at the ridge position and the other end passing through a connection port and communicating with the first sub-channel 463. Each diversion channel 20 is connected to multiple support parts 12. The second collection channel 42, the fourth collection channel 44, and the fifth collection channel 45 are all provided with diversion holes, which are connected to the corresponding diversion channels 20 through diversion pipes, thereby diverting a portion of the water into the diversion channels 20 through the diversion holes and diversion pipes, thus preventing overflow.

[0146] It should be noted that in this embodiment, the photovoltaic modules are a hybrid horizontal and vertical installation structure, but this is not limiting. In some other embodiments not shown in the figures, the photovoltaic modules can be installed vertically or horizontally. When the photovoltaic modules are only installed vertically, the drainage component 40 may only include the first collecting trough 41, and the corresponding support component may only include the first support component 50. It is also feasible to extend the first collecting trough 41 to the outside of the tile roof 100 to achieve drainage. When the photovoltaic modules are only installed horizontally, the drainage component 40 may only include the second collecting trough 42 and the drainage trough 46, and the corresponding support component may only include the second support component 60. This is also feasible, and no limitation is made in the embodiments of the invention.

[0147] According to another aspect of the present invention, a photovoltaic power generation system is also disclosed, comprising: the photovoltaic module mounting structure described above and a photovoltaic module, wherein the photovoltaic module is disposed on the photovoltaic module mounting structure.

[0148] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of the present invention, and the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
