Description

Photovoltaic system installation structure with safety attributes for flexible roofs Technical Field

[0001] This invention relates to the field of photovoltaic installation, and more particularly to a photovoltaic system installation structure for flexible roofs with safety attributes. Specifically, it relates to a photovoltaic mounting bracket assembly, a photovoltaic mounting assembly, and a photovoltaic system installation structure, which are mainly used for photovoltaic module installation on single-layer flexible roofs. Background Technology

[0002] Single-layer flexible roofing systems (hereinafter referred to as single-layer roofs) are characterized by their light weight, good waterproofing and thermal insulation performance, quick construction, easy maintenance, and long lifespan, and are widely used in the roofs of manufacturing plants, data centers, and transportation hubs. These roofs are flat and offer a large usable area, making them suitable for installing photovoltaic (PV) power stations. With the release of GB55030 "General Specification for Waterproofing of Buildings and Municipal Engineering" by the Ministry of Housing and Urban-Rural Development, the requirements for waterproofing materials, technologies, and performance of roofing systems are constantly increasing. Therefore, choosing the most suitable fixing method for a PV power station on a single-layer flexible roof is a difficult problem that requires careful consideration and selection. Currently, there are four common methods for connecting PV systems to single-layer roofs: the first is using concrete counterweights; the second is using steel column support; the third is using adhesive or welding support; and the fourth is using anchored PV brackets.

[0003] Regarding the methods of anchoring photovoltaic brackets, there are various styles of specialized anchoring structures. Some are directly welded without penetrating the roof, while others penetrate the roof and are fixed to the structure. Fixing methods include screw connections, riveting, and flip-anchor fixing, among others (e.g., the applicant's earlier application, patent number: CN202220823219.1, patent name: A Roof Equipment Installation Support; application number: 2023234849711, patent name: An Anchor and Anchoring Base for Protecting Roof Systems). These methods of fixing to the structure also differ in performance. For example, screw connections require a certain thickness of the roof system's steel plate, as well as specific requirements on the specifications and quantity of screws. Riveting is simple and quick, but considering the long-term stress of wind pressure and rain / snow, vibrations can occur, causing the riveting to loosen and reduce its strength. Furthermore, the single-point load-bearing mode has limited tensile strength; in areas with high wind load requirements, the riveted bases are more densely arranged, increasing the overall cost.

[0004] Photovoltaic system mounting brackets come in various styles and materials. Materials include galvanized steel and aluminum alloy, and structural styles include U-shaped perforated profiles, single-layer profile structures, and double-layer profile structures. Galvanized steel is susceptible to corrosion in high-humidity environments and coastal areas, which can reduce the overall performance and stability of the photovoltaic system. Aluminum alloy profiles may have flawed structural design; for example, the use of screws and T-nuts for mounting photovoltaic modules can result in the screws bearing the load under wind pressure, making them prone to screw loosening, connection failure, and profile tearing in extreme weather conditions, thus failing to meet the lifespan requirements of the photovoltaic project.

[0005] When photovoltaic systems are installed on a single-story roof, it is necessary to consider not only the wind uplift resistance requirements of the foundation, but also other requirements brought about by the climate and the inherent safety hazards. These include the load-bearing requirements of the photovoltaic system under extreme blizzards, the damaging impact of hail on photovoltaic modules, and the safety requirements of the photovoltaic system due to high-temperature combustion.

[0006] Meanwhile, the surface temperature of a single-layer roof can reach around 40 degrees Celsius in summer. However, due to the installation of photovoltaic (PV) module systems, although direct sunlight is blocked, the heat cannot dissipate from the bottom, effectively adding a layer of heat to the roof and further increasing the surface temperature, potentially reaching 60 degrees Celsius in extreme areas. When a fire hazard arises on the roof, high temperatures can indeed fuel the fire, as they accelerate the combustion reaction, enhance fuel combustion efficiency, and promote flame spread. Furthermore, when PV modules and the single-layer roof form channels, these channels, driven by airflow, can become pathways for the rapid spread of fire.

[0007] Therefore, solving the above-mentioned technical problems is a direction that those skilled in the art need to strive for. Summary of the Invention

[0065] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0066] Example 1: As shown in Figures 1-12, a photovoltaic mounting bracket assembly includes a main profile 1, a profile bracket 2, and a photovoltaic positioning component 3.

[0067] The top of the profile bracket 2 has a profile positioning groove 21 that passes through the left and right ends of the profile bracket 2. The lower middle part of the main profile 1 is inserted into the profile positioning groove 21. The opposite outer walls of the main profile 1 are respectively close to the front and rear inner walls of the profile positioning groove 21, or the opposite outer walls of the main profile abut against the front and rear inner walls of the profile positioning groove 21. In this embodiment, the front outer wall and the rear outer wall of the main profile 1 abut against the front inner wall and the rear inner wall of the profile positioning groove 21, respectively.

[0068] The main profile 1 is connected to the profile bracket 2 via a fastening mechanism;

[0069] The photovoltaic positioning component 3 is installed on the top of the main profile 1.

[0070] In this embodiment, the photovoltaic module 6 is directly mounted on the main profile, with the bottom surface of the photovoltaic module abutting against the top surface of the main profile, and its top surface being limited by the photovoltaic positioning component, which restricts the photovoltaic module to the main profile.

[0071] Referring to Figures 7-10, the present invention also provides a photovoltaic mounting assembly, including an anchor 51 and a fastening seat 52 connected to the top of the anchor 51, wherein the top of the fastening seat 52 is provided with a mounting screw hole 53.

[0072] It also includes the aforementioned photovoltaic mounting bracket assembly, wherein the bottom of the profile bracket 2 abuts against the top surface of the fastening seat 52, and the profile bracket 2 is screwed to the mounting screw hole 53 through the profile positioning groove 21 by a mounting bolt 22, and the mounting bolt 22 connects the profile bracket 2 to the fastening seat 52.

[0073] In this embodiment, the fastening seat 52 is connected to the anchor 51 via the connecting rod 54. The anchor 51 is a flip anchor with a notch 55. One end of the notch 55 is connected to one end of the anchor 51. The bottom of the connecting rod 54 is rotatably connected to the inner end of the notch 55. During installation, a hole is drilled in the roof 7. Then, the anchor is rotated so that the connecting rod is inside the notch. At this time, the connecting rod and the anchor are basically on the same straight line. Then, the bottom of the connecting rod and the hole through the roof are inserted into the lower part of the roof. Since the anchor is no longer subjected to external force, the anchor is flipped by its own weight, causing the notch to disengage from the connecting rod. An installation rod is provided on the anchor. The installation rod is rotatably connected to the anchor. The connecting rod is screwed to the installation rod. Then, the connecting rod is rotated so that the connecting rod is screwed relative to the installation rod, which will drive the anchor to move upward. When the top surface of the anchor is against the bottom surface of the roof, the fastening seat is connected to the top of the connecting rod. Preferably, a support column 56 is also fitted on the connecting rod 54. The support column is located between the fastener and the roof. The bottom of the fastener and the top of the connecting rod are screwed together, so that the bottom surface of the support column abuts against the roof and the anchor abuts against the bottom surface of the roof, thus realizing the installation of the anchor and the fastener. After installation is complete, the photovoltaic mounting bracket assembly is installed. When connecting the photovoltaic mounting bracket assembly and the fastening base, the profile bracket is placed directly on the top surface of the fastening base. Then, the bottom of the mounting bolt is threaded through the mounting screw holes on the top of the profile bracket and the fastening base to connect the profile bracket and the top of the fastening base. Then, the main profile is inserted into the profile positioning groove, and the main profile and the profile bracket are connected by the fastening mechanism to fix the main profile and the profile bracket. Finally, the photovoltaic positioning component is installed (or the photovoltaic positioning component is pre-installed on the main profile. After the main profile is installed, the photovoltaic module is installed. After the photovoltaic module is positioned, the position of the photovoltaic positioning component is adjusted to limit the photovoltaic module on the main profile).

[0074] The weight and external forces acting on the photovoltaic modules are transmitted to the main profile. Since the main profile is directly supported by the profile bracket, which rests directly against the fastener, the force on the top of the fastener is more evenly distributed. Simultaneously, the entire photovoltaic system comprises multiple photovoltaic mounting bracket assemblies and multiple photovoltaic mounting modules. Because the photovoltaic module brackets are mounted on the main profile, these multiple photovoltaic mounting bracket assemblies and photovoltaic mounting modules form a unified whole, resulting in more even force distribution throughout the system. Furthermore, the entire system is primarily subjected to vertical loads, preventing uneven stress patterns and effectively improving the safety of the entire photovoltaic system. This is particularly beneficial for single-layer flexible roofs, ensuring their flatness.

[0075] Referring to Figure 3, the bottom of the profile positioning groove 21 is provided with a mounting hole 23 that communicates with the bottom of the profile bracket 2. The mounting hole allows the bottom of the mounting bolt to pass through the mounting hole and be screwed into the mounting screw hole at the top of the fastener. The screw head of the mounting bolt rests against the bottom surface of the profile positioning groove (or the mounting hole is a stepped hole, with the screw head of the mounting bolt inside the stepped hole and not exposed outside the profile positioning groove), enabling a quick connection between the profile bracket and the fastener, thereby improving installation convenience.

[0076] Referring to Figures 1-4, a bottom positioning groove 11 is provided at the bottom of the front and rear sides of the main profile 1, and the bottom positioning groove 11 is arranged parallel to the extension direction of the main profile 1.

[0077] The front inner wall and the rear inner wall of the profile positioning groove 21 are respectively provided with at least one positioning slot 24 that passes through the left and right ends of the profile bracket 2. The bottom positioning groove 11 of the main profile 1 on the corresponding side is respectively set directly opposite to at least one of the positioning slots 24 on the corresponding side.

[0078] The fastening mechanism consists of two sets, each including a pin 25 and a fastening bolt 26.

[0079] The front and rear outer walls of the profile bracket are respectively provided with positioning screw holes 27 that communicate with the profile positioning groove 21, and each positioning screw hole 27 is connected to multiple positioning slots 24 on the opposite side of the profile positioning groove 21.

[0080] The two sets of fastening mechanisms are respectively arranged on the front and rear sides of the main profile 1, and the inner end of the pin 25 of each fastening mechanism is inserted into a bottom positioning groove 11, and the outer end of the pin 25 is inserted into a positioning slot 24 on the corresponding side.

[0081] Each of the fastening bolts 26 is screwed into a positioning screw hole 27, and the inner end of the fastening bolt 26 abuts against the outer side wall of the corresponding pin 25. The fastening bolts 26 and the pin 25 limit the main profile 1 to be positioned on the profile bracket 2.

[0082] In this embodiment, the fastening bolt is a set screw. The length of the main profile is generally greater than the length of the profile bracket. During installation of the main profile and profile bracket, the main profile is directly placed into the profile positioning groove, or the end of the main profile is inserted from one end of the profile positioning groove into the profile mounting groove. After the main profile is positioned correctly (after the axial position of the main profile is adjusted, taking the left-right direction as an example, the distance between the end of the main profile and the profile bracket is adjusted to a preset value), the bottom positioning groove will be directly aligned with... A positioning slot is formed, with a corresponding bottom positioning slot connected to the positioning slot. Pins are then inserted into the interconnected bottom and positioning slots, supporting the main profile via the pins on the front and rear sides. The main profile is thus supported within the profile positioning slot (on the profile bracket). Tightening the fastening bolts inwards pushes the pins towards the inner end of the bottom positioning slot, securing the pins tightly. This method completely limits the main profile to the profile bracket. Instead of using the bottom of the profile positioning slot for support, the main profile, subjected to the weight of the photovoltaic module and the external forces transmitted by the module, receives overall support directly through the contact points of the pins. This symmetrical arrangement results in a relatively large bearing area on the profile bracket, with more even force distribution on both sides. This enhances the stability of the entire photovoltaic system, ensuring that the entire system and roof experience vertical loads as much as possible, effectively guaranteeing the stability of the entire system.

[0083] The width of the pin is equal to or slightly less than the sum of the widths of the bottom positioning groove and the positioning slot. The pin restricts the vertical movement of the main profile. After the fastening bolts tighten the pin, they can prevent the main profile from moving axially relative to the profile bracket, and also play an axial limiting role.

[0084] Referring to Figures 2-4, one end of the pin 25 is a guide head 28, and the other end of the pin 25 is provided with an outwardly extending gripping plate 29. The gripping plate 29 is located at the left or right end of the profile bracket 2.

[0085] In this embodiment, taking the perspective of the attached drawing as an example, the guide head is located at the left end of the pin. The guide head has a tapered or figure-eight shaped structure with a smaller left side and a larger right side. After the main profile is inserted into the profile positioning groove, it is directly inserted into the bottom positioning groove and positioning slot through the guide head. The width of the left end of the guide head will be less than the sum of the widths of the two, and the guide head plays an insertion guiding role, making it easy for the pin to be inserted into the bottom positioning groove and positioning slot. At the same time, the gripping plate is set up with the gripping plate extending outward. In this way, the sum of the widths of the pin and the gripping plate will be greater than the sum of the widths of the positioning slot and the bottom positioning groove. After the pin is inserted, the gripping plate will be outside the profile bracket (right end in the attached drawing). When it is necessary to disassemble or adjust the main profile, the operator can directly grasp the main plate and pull the pin away from the profile bracket to achieve quick disassembly of the pin, thereby facilitating the disassembly or adjustment of the main profile.

[0086] Referring to Figures 1-4, each side of the profile positioning groove 21 has at least two positioning slots 24 on its inner wall, and the positioning slots 24 are spaced apart from bottom to top. In this embodiment, each side of the profile positioning groove has three positioning slots spaced apart from bottom to top, and the corresponding positioning screw holes are connected to these three positioning slots. In this way, no matter which positioning slot the pin is inserted into, the fastening bolt can hold the pin and limit the position of the main profile.

[0087] In this embodiment, by setting multiple positioning slots, during on-site construction, the bottom positioning slot of the main profile can be aligned with the positioning slots at different heights according to the required installation height of the photovoltaic modules relative to the roof. Then, positioning pins are inserted into the corresponding positioning slots and the bottom positioning slot, thus adjusting the height of the main profile relative to the roof. Simultaneously, if there is a certain height difference between the roof positions where different photovoltaic mounting bracket components are installed, and the main profile needs to be installed as horizontally as possible to prevent tilting, the height of the main profile relative to the bottom surface of the positioning slot can also be adjusted to ensure the main profile is as level as possible.

[0088] Therefore, in this invention, since the main profile needs to be height adjusted, a bottom positioning groove and multiple positioning slots are used for height adjustment and limiting. A pin is then used to limit the main profile. Compared to directly using bolts for limiting (where the main profile does not have a bottom positioning groove, the profile bracket does not have positioning slots, a screw hole is provided on the front and rear sides of the main profile, and holes at different heights are provided on the profile bracket, with bolts threaded through these holes and screws), this method effectively increases the contact area between the main profile and the profile bracket, thereby improving the stability of the entire photovoltaic system. This ensures that the entire photovoltaic system and the roof are subjected to vertical loads as much as possible, effectively guaranteeing the stability of the entire system.

[0089] Meanwhile, this invention employs a pin-type clamp-locking structure, which differs from existing screw and T-nut locking structures. Furthermore, this invention utilizes a surface support structure, enhancing its performance (conventional force-bearing patterns include point, line, and surface force-bearing patterns. At a constant pressure, the larger the force-bearing area, the lower the pressure intensity and the smaller the effect of the pressure; conversely, at a constant force-bearing area, the greater the pressure intensity and the greater the effect of the pressure. Therefore, the surface support force-bearing pattern is greater than the line support force-bearing pattern and also greater than the point support force-bearing pattern), significantly protecting the force-bearing surface area and thus achieving the function of roof system protection.

[0090] Referring to Figures 1-3 and 7-9, the photovoltaic positioning component 3 is at least one set. The top left and / or right side of the photovoltaic positioning component is provided with a locking plate 321. The locking plate 321 is set directly opposite the main profile 1. The locking plate is provided on at least one side of the top left or right side of the photovoltaic positioning component. A locking plate can be provided on the top left side of the photovoltaic positioning component, or a locking plate can be provided on the top right side of the photovoltaic positioning component, or a locking plate can be provided on the top left and right sides of the photovoltaic positioning component respectively. The bottom front side and rear side of the photovoltaic positioning component 3 are respectively provided with a first snap-fit ​​component 33 extending outward and downward.

[0091] The main profile 1 has a locking strip 12 extending outward and downward on its top front and rear sides, and each locking strip 12 is connected to each of the first locking members 33. The photovoltaic positioning member 3 is installed on the top of the main profile 1 by the first locking member 33 and the locking strip 12.

[0092] In this embodiment, the first snap-fit ​​component has a slightly elastic structure. When installing the photovoltaic positioning component and the main profile, the first snap-fit ​​component is placed directly against the top of the main profile, and downward pressure is applied. This causes the first snap-fit ​​component to deform slightly, pass the corresponding locking strip, and automatically recover, thus achieving the snap-fit ​​between the first snap-fit ​​component and the locking strip. Alternatively, the first snap-fit ​​component can be a non-elastic structure. During installation, the photovoltaic positioning component is first placed at the end of the main profile. After the first snap-fit ​​component is aligned with the locking strip, it moves towards the main profile, causing the locking strip to directly engage with the first snap-fit ​​component. Then, the photovoltaic positioning component is moved along the main profile, achieving rapid installation of the photovoltaic positioning component.

[0093] In this invention, the first snap-fit ​​component 33 includes an inclined plate 331 and a hook 332. The inclined plate is inclined downwards from the inside to the outside, with its inner end connected to the side wall of the photovoltaic positioning component and its outer end located below the outer side of the photovoltaic positioning component. The outer end of the hook is connected to the bottom of the inclined plate and is located on the inner side of the inclined plate. A snap-fit ​​groove is formed between the hook and the inclined plate, which is a V-shaped or arc-shaped structure. The outer side of the snap-fit ​​strip is parallel to the inclined plate and is directly snapped into the snap-fit ​​groove, thus achieving snap-fit ​​limiting between the snap-fit ​​strip and the first snap-fit ​​component and preventing the photovoltaic positioning component from moving upwards and detaching from the main profile. The snap-fit ​​plate can be used to abut against the top surface of the edge of the photovoltaic module to limit the photovoltaic module and prevent it from moving upwards and detaching from the main profile. The photovoltaic positioning component is located on the side of the photovoltaic module and can restrict the axial movement of the photovoltaic module relative to the main profile.

[0094] Referring to Figures 1-3 and 7-9, the photovoltaic positioning component 3 includes a bottom connecting block 31 and a photovoltaic limiting part 32. The photovoltaic limiting part 32 is connected to the bottom connecting block 31 via an adjusting bolt 322. Two first snap-fit ​​parts 33 are respectively installed on the bottom front and rear sides of the bottom of the bottom connecting block 31. The photovoltaic limiting part 32 is located directly above the bottom connecting block 31, and the snap-fit ​​plate 321 is located on the photovoltaic limiting part 32.

[0095] The top surface of the bottom connecting block 31 is provided with a connecting screw hole, the bottom of the connecting screw hole is connected to the bottom surface of the bottom connecting block 31, and the connecting screw hole is located between the first snap-fit ​​members 33 on both sides. The photovoltaic limiting part 32 is provided with a clearance hole, and the bottom of the adjusting bolt 322 passes through the clearance hole and is connected to the connecting screw hole.

[0096] In this embodiment, the connection screw hole and adjusting bolt are configured so that after the first snap-fit ​​and the snap-fit ​​strip are engaged, the photovoltaic positioning component can move axially relative to the main profile. Therefore, during photovoltaic module installation, the position of the photovoltaic positioning component is slid according to the position of the photovoltaic module, so that the snap-fit ​​plate is above the side of the photovoltaic module. Then, the adjusting bolt is rotated, and the screw head of the adjusting bolt will abut against the top surface of the photovoltaic limiting part. When the adjusting bolt is rotated downward, it will drive the photovoltaic limiting part to move downward, and make the snap-fit ​​plate abut against the photovoltaic module. The snap-fit ​​plate will press the photovoltaic module tightly onto the main profile. At the same time, since the adjusting bolt and the connection screw hole are screwed together, the bottom connecting block will be pulled upward by the adjusting bolt, causing the bottom connecting block and the first snap-fit ​​to move slightly upward, so that the first snap-fit ​​tightly hooks the snap-fit ​​strip, thereby preventing the bottom connecting block from moving axially relative to the main profile, thus achieving the limiting of the photovoltaic positioning component and the photovoltaic module. Preferably, in this embodiment, the bottom of the adjusting bolt abuts against the top surface of the main profile, further restricting the axial movement of the photovoltaic positioning component relative to the main profile. Thus, by setting the adjusting bolt, it is possible to limit the photovoltaic positioning component and the main profile, and also to install and limit the photovoltaic module.

[0097] Referring to Figures 1-3 and 7-9, a retaining plate 321 is provided on the photovoltaic limiting part 32 on one side of the clearance hole, or a retaining plate 321 is provided on the photovoltaic limiting part 32 on both sides of the clearance hole, and the retaining plate 321 is positioned directly opposite the main profile 1.

[0098] In this embodiment, if photovoltaic modules need to be installed on both sides of the photovoltaic positioning component, then both sides of the photovoltaic limiting part are provided with extended clamping plates, which limit the photovoltaic modules on both sides respectively. If the photovoltaic positioning component only has photovoltaic modules on one side that need to be limited, then the photovoltaic limiting part uses a clamping plate with an extension on only one side, which limits the outermost photovoltaic module. The appropriate photovoltaic limiting part can be selected according to the actual situation. In the attached drawings of this embodiment, two sets of photovoltaic positioning components are installed on the main profile. One set of photovoltaic positioning components has two clamping plates, and the other set of photovoltaic positioning components has one clamping plate.

[0099] Furthermore, in this invention, the photovoltaic modules are arranged according to the roof layout area, therefore, there will be splicing of the main profiles. Therefore, in this embodiment, a profile connector 13 is also provided. The main profile 1 has a main cavity 14 extending through both ends in its middle section, and one end of the profile connector 13 is inserted into the main cavity 14. The profile connector 13 connects two adjacent main profiles 1 arranged on the same axis, and both ends of the profile connector 13 are respectively inserted into the main cavities 14 of the two adjacent main profiles 1.

[0100] By connecting two adjacent main profiles on the same axis using profile connectors, the main profiles in the same row of the entire photovoltaic system can form a whole structure, which can be supported by multiple profile brackets, thus ensuring that the main profiles can stably and firmly support and limit the photovoltaic modules.

[0101] Furthermore, to ensure that the profile connector and the main profile act as a limiting element during installation and connection, and to consider the thermal expansion and contraction between the main profile and the profile connector, a protruding part 15 (one protrusion shown in the attached figure) is provided on one outer wall of the profile connector 13. The outer surface of the protrusion 15 and other outer surfaces of the profile connector 13 respectively abut against the inner wall of the main cavity 14. The protrusion abuts against the inner wall of the main cavity of the main profile, and is fixed by one side. There is a certain gap between the profile connector and the main profile on the side of the protrusion. This gap can be used as a spacer for expansion and contraction, which can ensure the firmness and stability of the installation, and at the same time meet the deformation requirements of the main profile and the profile connector.

[0102] Referring to Figures 11-14, the present invention also provides a photovoltaic system installation structure for a flexible roof with safety attributes, including the photovoltaic mounting bracket assembly described above. The photovoltaic mounting bracket assembly is in multiple sets, and the photovoltaic module mounting position is formed above the multiple sets of photovoltaic mounting bracket assemblies.

[0103] A gap is formed between two adjacent main profiles 1, and multiple fire-blocking components 16 are also provided within the gap. A fire-proof partition 17 is formed between adjacent fire-blocking components, and the two ends of the fire-blocking components abut against the top surface of the adjacent main profiles on both sides.

[0104] In this method, even if a fire occurs, the fire will be kept within the corresponding fire compartment as much as possible. At the same time, when a fire occurs within a fire compartment, the fire baffles and main profiles can slow the spread of the fire, thereby providing more time for rescue and extinguishing, reducing property damage caused by the fire, and also reducing safety hazards.

[0105] Referring to Figures 11-14, the fire baffle assembly 16 includes at least one fire baffle plate 18. A connecting plate 19 is provided on the top of the fire baffle plate 18. The two ends of the connecting plate 19 are respectively disposed on the top two sides of the fire baffle plate 18. The bottom ends of the connecting plate 19 respectively abut against the top surface of the adjacent two main profiles 1. The fire baffle plate 18 is disposed between the adjacent main profiles 1, and the side of the fire baffle plate 18 is close to or abuts against the side wall of the adjacent main profile 1.

[0106] In this invention, the fire-blocking component has various structures. Taking a fire-blocking plate as an example, the width of the fire-blocking plate is equal to or slightly smaller than the distance between two adjacent main profiles. Preferably, the side of the fire-blocking plate abuts against the side wall of the corresponding main profile. The two ends of the connecting plate are located outside the two ends of the fire-blocking plate, and the bottom surface of the end of the connecting plate directly abuts against the top surface of the corresponding side main profile. In this way, the fire-blocking plate is placed directly on the main profile, which facilitates installation. A photovoltaic module is installed at the photovoltaic module mounting position. Since the photovoltaic module is installed above the main profile, it will be above the fire-blocking plate, i.e., above the connecting plate, thus limiting the position of the fire-blocking plate. Simultaneously, the fire-blocking plate itself has weight, which also serves as a limiting element. Furthermore, the presence of the photovoltaic positioning component also restricts the movement of the connecting plate on the main profile.

[0107] Referring to Figures 11-14, a strip-shaped through groove 20 is provided in the middle of the fire baffle 18, and a relief groove 21 is provided on the fire baffle 18 at both ends of the strip-shaped through groove 20. A limiting plate 22 is provided in the relief groove 21, and one end of the limiting plate 22 is connected to the top or bottom of the relief groove 21.

[0108] The fire baffle assembly 16 includes at least two fire baffle plates 18, with the side walls of adjacent fire baffle plates 18 in contact. The limiting plate 22 of the fire baffle plate 18 is inserted into the relief groove 21 of the adjacent fire baffle plate 18, and the ends of the connecting plates 19 of the fire baffle plates 18 at both ends abut against the top surface of the adjacent main profile 1.

[0109] In this invention, due to varying installation conditions on different roofs, the distance between two adjacent main profiles will not be exactly the same as the length of the fire baffle, and the distance between the two main profiles will also be adjusted, sometimes wide, sometimes narrow, or the adjacent main profiles will not be completely parallel. Therefore, it is difficult to keep the width of the fire baffle consistent with the distance between two adjacent main profiles. In this invention, to ensure that the end of the fire baffle is close to or abuts against the side wall of the corresponding side main profile, a strip groove and a limiting plate are provided on the fire baffle. In the initial state, the top of the limiting plate is connected to the top surface of the relief groove, the limiting plate is located in the relief groove, and there is a gap between the sides and bottom of the limiting groove and the relief groove. Then, depending on the gap between adjacent main profiles, two, three, or more fire baffles are directly connected. Taking the connection of two fire baffles as an example, during connection, the front side of the left fire baffle rests against the rear side of the right fire baffle, and the bottom surface of the connecting plate of the left fire baffle rests against the top surface of the connecting plate of the right fire baffle (the width of the connecting plate is greater than the thickness of the fire baffle, and the top of the fire baffle and the bottom of the connecting plate are connected on one side, so the connecting plate can rest against the top surface of the adjacent connecting plate). The left end of the connecting plate of the left fire baffle rests against the top surface of the left main profile, and the right end of the right connecting plate rests against the top surface of the right main profile. At the same time, the right end limiting plate of the left fire baffle is aligned with the strip groove on the right fire baffle. Then, the limiting plate is bent and inserted into the strip groove, and then bent again, so that the limiting plate becomes a U-shaped structure or a Z-shaped structure. Similarly, the left end limiting plate of the right fire baffle is aligned with the strip groove on the left fire baffle. This limiting plate is inserted into the strip groove of the left fire baffle, and then bent to form a U-shaped or Z-shaped structure, as shown in Figures 13 and 14. This U-shaped or Z-shaped limiting plate, inserted into the strip groove, connects adjacent fire baffles, allowing for the connection of two fire baffles. Adjusting the length of the fire baffle assembly makes it suitable for applications with varying spacing between adjacent main profiles, thus broadening its applicability.

[0110] Meanwhile, the bottom of the fire baffle will be located above the bottom of the main profile, so as not to affect the airflow or the heat dissipation of the photovoltaic modules in the fire compartment.

[0111] In this invention, the construction of the entire photovoltaic system follows these steps:

[0112] a. Mark the roof according to the design drawings and confirm the connection and fixing points;

[0113] b. Clean the single-layer roof system and use special tools to make holes in the roof;

[0114] c. Insert the anchors in the photovoltaic installation components into the underside of the roof through the opening. The anchors will automatically flip over. After adjusting the distance between the anchors and the fasteners, use construction tools to lock the fasteners, thereby achieving rapid fixation of the photovoltaic installation components and the roof. Then, use a hot air welding gun to weld the reserved waterproof skirt of the fasteners to the roof waterproof layer to achieve waterproof sealing.

[0115] d. Place the profile bracket on the fastening base and adjust the angle. Secure the top of the profile bracket and the fastening base with the mounting bolts. Place the main profile into the profile positioning slot of the profile bracket. Determine the installation height of the main profile according to the on-site installation height. Insert the pin for positioning. At the same time, the pin's gripper should face the ridge. Then, through the pre-drilled positioning screw holes on the side, rotate the fastening bolts and tighten the pin.

[0116] e. Install the fireproof components on the main profile, then install the photovoltaic positioning components on the main profile in sequence, and then put in the photovoltaic module (photovoltaic panel). By rotating the adjusting bolts, lock the clamp of the photovoltaic positioning component to the photovoltaic module to complete the installation.

[0117] Example 2: A photovoltaic system installation structure for a flexible roof with safety attributes. In this example, the structure of the photovoltaic mounting bracket assembly differs from that in Example 1. In Example 1, three positioning slots are provided at intervals from bottom to top on the front and rear inner walls of the profile positioning groove. During use, the corresponding positioning slot is selected according to the actual situation to adjust the height of the main profile. In this example, the difference from Example 1 is as follows: As shown in Figure 15, the front and rear inner walls of the profile positioning groove 21 are respectively provided with a positioning slot 24 penetrating both ends of the profile bracket 2. The positioning slots 24 on both sides are arranged opposite each other. The bottom positioning grooves 11 on both sides of the main profile 1 are respectively positioned opposite one of the positioning slots 24. The inner end of the pin 25 of each fastening mechanism is inserted into one of the bottom positioning grooves 11, and the outer end of the pin 25 is inserted into one of the positioning slots 24. Each positioning screw hole 27 is connected to one of the positioning slots 24.

[0118] In this embodiment, only one positioning slot is provided on the front inner wall and the rear inner wall of the profile positioning groove (in Embodiment 1, three positioning slots are provided on each side of the profile positioning groove; in this embodiment, only one positioning slot is provided on each side) to fix the height of the main profile. In this way, the corresponding height slots can be pre-processed according to the required installation scenario and height (the height range can meet the installation conditions required on site), which can reduce the manufacturing difficulty. At the same time, the reduction in the number of positioning slots can reduce the number of slots on the profile bracket, thereby effectively ensuring and improving the strength of the profile bracket, ensuring its strength, firmness and lifespan during installation and use.
