Description

Technical Field

[0001] The present invention relates to the field of photovoltaic installation, and in particular to a photovoltaic system installation structure of a flexible roof with safety attributes, in particular to a photovoltaic installation bracket assembly, a photovoltaic installation assembly and a photovoltaic system installation structure, which are mainly used for the installation of photovoltaic components on a single-layer flexible roof. Background Art

[0002] The single-layer flexible roof system (hereinafter referred to as the single-layer roof) has the characteristics of light weight, good waterproof and thermal insulation performance, fast construction, easy maintenance, and long life. It is widely used in building roofs such as manufacturing plants, data centers and transportation hubs. The roof of this type of building is flat and has a large usable area, which is more suitable for installing photovoltaic 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 waterproof materials, technologies and performance of roof systems are constantly increasing. How to choose the photovoltaic power station fixing method that best matches the single-layer flexible roof is a difficult problem that requires careful consideration and careful selection. At present, there are four common ways to connect photovoltaic systems to single-layer roofs on the market. The first is the concrete counterweight block method, the second is the steel column support method, the third is the adhesive and welding support fixation method, and the fourth is the anchoring photovoltaic bracket method.

[0003] Among them, there are many styles of special anchoring structures for anchoring photovoltaic brackets, some of which are directly welded without penetrating the roof, and some are fixed to the structure by penetrating the roof. The fixing methods include screw connection, riveting fixation, flip anchor fixation and other structural forms (such as the applicant's prior application, patent number: CN202220823219.1, patent name: A roof equipment installation support, application number: 2023234849711, patent name: Anchor and anchor base that can protect the roof system). Among them, there are also performance differences with the structural fixation method. For example, the screw connection fixation method has requirements for the thickness of the steel plate of the roof system, and also has requirements for the specifications and number of screws; the riveting fixation method is simple and fast, but considering that the roof system is subjected to the long-term wind pressure pulling and rain and snow pressure, vibration will occur, and the riveted form will become loose, reducing the firmness. In addition, the tensile bearing capacity of the single-point force mode is limited. In areas with high wind load requirements, the riveted base is arranged more densely, which increases the overall cost.

[0004] The photovoltaic system mounting bracket also has different styles and structural systems of different materials. The materials are divided into galvanized and aluminum alloy materials, and the structural styles are divided into U-shaped perforated profiles, single-layer profile structures and double-layer structural profiles. Among them, galvanized materials have the hidden danger of easy corrosion in high-humidity environments and coastal areas, which will reduce the overall performance and stability of the photovoltaic system. Aluminum alloy profiles may have unreasonable structural design. Photovoltaic modules are installed with screws and T-nuts. When subjected to wind pressure, they are force-bearing structures at the screw points. In extreme climates, it is easy to cause screws to fall off, joints to fail, and profiles to tear, which cannot meet the life requirements of the project photovoltaic.

[0005] When photovoltaic power is installed on a single-layer roof, it is necessary not only to consider the basic wind resistance requirements, but also to comprehensively consider other requirements brought by the climate and the requirements caused by its own safety hazards, such as the support and bearing requirements of the photovoltaic system under extreme blizzards, the requirements for the damage of hail to photovoltaic modules, and the safety requirements of high-temperature combustion to the photovoltaic system.

[0006] At the same time, the surface temperature of a single-layer roof can reach about 40 degrees in summer. However, due to the installation of a photovoltaic module system, although it is isolated from direct sunlight, the temperature cannot be dissipated at the bottom, which is equivalent to adding a cover to the roof, raising the surface temperature of the single-layer roof, which may reach 60°C in extreme areas. When there is a fire hazard on the roof, high temperature can indeed help to increase the fire, because high temperature can accelerate the rate of combustion reaction, enhance the combustion efficiency of fuel, and promote the spread of flames. In addition, when photovoltaic modules and single-layer roofs form channels, these channels may become channels for the rapid spread of fire under the action of wind flow.

[0007] Therefore, how to solve the above technical problems is the direction that technical personnel in this field need to work hard on. Summary of the invention

[0063] The present invention will be further described below in conjunction with the accompanying drawings and embodiments:

[0064] Example 1: See Figure 1-12 As shown, a photovoltaic mounting bracket assembly includes a main profile 1, a profile bracket 2 and a photovoltaic positioning member 3.

[0065] 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 side outer walls of the main profile 1 are respectively arranged close to the front and rear side inner walls of the profile positioning groove 21, or the opposite side outer walls of the main profile are respectively against the front and rear side inner walls of the profile positioning groove 21; in this embodiment, the front side outer wall and the rear side outer wall of the main profile 1 are respectively against the front side inner wall and the rear side inner wall of the profile positioning groove 21.

[0066] The main profile 1 is connected to the profile bracket 2 via a fastening mechanism;

[0067] The photovoltaic positioning member 3 is installed on the top of the main profile 1 .

[0068] In this embodiment, the photovoltaic component 6 is directly installed on the main profile, with the bottom surface of the photovoltaic component against the top surface of the main profile and the top of the photovoltaic component limited by the photovoltaic positioning member, which restricts the photovoltaic component on the main profile.

[0069] See also Figure 7-10 As shown, the present invention further provides a photovoltaic installation assembly, comprising an anchor 51 and a fastening seat 52 connected to the top of the anchor 51, and a mounting screw hole 53 is provided on the top of the fastening seat 52;

[0070] It also includes the above-mentioned photovoltaic mounting bracket assembly, the bottom of the profile bracket 2 is against the top surface of the fastening seat 52, the profile bracket 2 is screwed to the mounting screw hole 53 through a mounting bolt 22 passing through the profile positioning groove 21, and the mounting bolt 22 connects the profile bracket 2 to the fastening seat 52.

[0071] The anchor 51 is provided with a notch 55, one end of the notch 55 is connected to one end of the anchor 51, and the bottom of the connecting rod 54 is rotatably connected to the inner end of the notch 55. When installing, a hole is drilled on the roof 7, and then the anchor is rotated first so that the connecting rod is in the notch. At this time, the connecting rod and the anchor are basically in the same straight line, and then the bottom of the connecting rod and the anchor are inserted into the bottom of the roof through the hole in the roof. At this time, since the anchor is no longer subjected to external force, the anchor is flipped under its own weight, so that the notch is separated from the connecting rod. Among them, a mounting rod is set on the anchor, and the mounting rod and the anchor are rotatably connected. The connecting rod is screwed to the mounting rod, and then the connecting rod is rotated so that the connecting rod is screwed relative to the mounting 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 mounted on the connecting rod 54, and the support column is located between the fastening seat and the roof. The bottom of the fastening seat and the top of the connecting rod are screwed together, so that the bottom surface of the support column is against the roof, and the anchor is against the bottom surface of the roof, thereby realizing the installation of the anchor and the fastening seat. After the installation is completed, the photovoltaic mounting bracket assembly is installed. When the photovoltaic mounting bracket assembly and the fastening seat are connected, the profile bracket is directly placed on the top surface of the fastening seat, and the bottom of the mounting bolt is then passed through the profile bracket and the mounting screw holes on the top of the fastening seat to screw them together to achieve the connection between the profile bracket and the top of the fastening seat. The main profile is then inserted into the profile positioning groove, and the main profile and the profile bracket are connected by the fastening mechanism to achieve the fixation of the main profile and the profile bracket. Finally, the photovoltaic positioning piece is installed (or the photovoltaic positioning piece is pre-installed on the main profile, and the photovoltaic component is installed after the main profile is installed. After the photovoltaic component is placed, the position of the photovoltaic positioning piece is adjusted, and the photovoltaic component is limited to the main profile by the photovoltaic positioning piece).

[0072] The weight of the photovoltaic module and the external force it is subjected to will be transmitted to the main profile. Since the main profile is directly supported by the profile bracket, the profile bracket directly rests on the fastening seat, making the top of the fastening seat more evenly stressed. At the same time, the entire photovoltaic system will have multiple photovoltaic mounting bracket assemblies and multiple photovoltaic mounting assemblies. Since the photovoltaic module bracket is installed on the main profile, that is, multiple photovoltaic mounting bracket assemblies and multiple photovoltaic mounting assemblies will form a whole, the stress of the entire system will be more even. At the same time, the entire system is basically only subjected to vertical loads, and there will be no uneven tilted force mode, which can effectively improve the safety of the entire photovoltaic system, especially for single-layer flexible roofs, and can effectively ensure the flatness of single-layer flexible roofs.

[0073] See also Figure 3As shown, the bottom of the profile positioning groove 21 is provided with a mounting hole 23 connected to the bottom of the profile bracket 2. With the arrangement of the mounting hole, the bottom of the mounting bolt passes through the mounting hole and the mounting screw hole at the top of the fastening seat for screw connection, and the screw head at the top of the mounting bolt abuts against the bottom surface of the profile positioning groove (or the mounting hole is a stepped hole, and the screw head of the mounting bolt is in the stepped hole and does not leak out of the profile positioning groove), so as to realize the quick connection between the profile bracket and the fastening seat, thereby improving the convenience of installation.

[0074] See also Figure 1-4 As shown, a bottom positioning groove 11 is respectively provided at the bottom of the front side and the rear side of the main profile 1, and the bottom positioning groove 11 is arranged parallel to the extension direction of the main profile 1;

[0075] 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 penetrating the left and right ends of the profile bracket 2, and the bottom positioning slot 11 on the corresponding side of the main profile 1 is respectively arranged opposite to at least one positioning slot 24 on the corresponding side.

[0076] The fastening mechanism is divided into two groups, and the fastening mechanism includes a latch 25 and a fastening bolt 26;

[0077] The front outer wall and the rear outer wall of the profile bracket are respectively provided with positioning screw holes 27 connected to the profile positioning groove 21, and each of the positioning screw holes 27 is connected to the plurality of positioning slots 24 on the opposite side of the profile positioning groove 21;

[0078] The two sets of fastening mechanisms are respectively arranged at the front and rear sides of the main profile 1, and the inner end of the latch 25 of each fastening mechanism is respectively inserted into one of the bottom positioning grooves 11, and the outer end of the latch 25 is inserted into one of the positioning slots 24 on the corresponding side;

[0079] Each of the fastening bolts 26 is screwed into one of the positioning screw holes 27 , and the inner end of the fastening bolt 26 abuts against the outer side wall of the corresponding latch 25 . The fastening bolts 26 and the latch 25 limit the main profile 1 on the profile bracket 2 .

[0080] In this embodiment, the fastening bolt is a top screw, wherein the length of the main profile is generally greater than the length of the profile bracket. When the main profile and the profile bracket are installed, the main profile is directly placed in the profile positioning groove, or the end of the main profile is inserted from one end of the profile positioning groove into the profile installation groove. After the position of the main profile is adjusted (after the axial position of the main profile is adjusted, taking the left and right directions as an example, the distance between the end of the main profile and the profile bracket is adjusted to the preset value), the bottom positioning groove will be directly opposite to the bottom of the profile bracket. A positioning slot, the corresponding bottom positioning slot and the corresponding positioning slot are connected, and then the pin is inserted into the interconnected bottom positioning slot and positioning slot, and the main profile is supported by the front and rear side pins, so that the main profile is supported in the profile positioning slot (on the profile bracket) by the pin, and then the fastening bolt is screwed inward, so that the fastening bolt pushes the pin to move toward the inner end of the bottom positioning slot, and the fastening bolt tightens the pin, so that the two pins can completely limit the main profile on the profile bracket. In this way, the bottom of the profile positioning slot is not used for support. The main profile is subjected to the gravity of the photovoltaic module and the external force transmitted by the photovoltaic module, and will be directly supported as a whole through the contact position of the pin, and it is symmetrically arranged. In this way, the force area of ​​the profile bracket is relatively large, and the force on both sides is relatively uniform, and the force area is also relatively large, which can improve the stability of the entire photovoltaic system, so that the entire photovoltaic system and the roof are subjected to vertical loads as much as possible, effectively ensuring the stability of the entire system.

[0081] Among them, the width of the pin will be equal to the sum of the widths of the bottom positioning groove and the positioning card slot, or slightly smaller than the sum of the widths of the bottom positioning groove and the positioning card slot. The pin can limit the up and down movement of the main profile. After the fastening bolt tightens the pin, it can prevent the main profile from moving axially relative to the profile bracket, and also play an axial limiting role.

[0082] See also Figure 2-4 As shown, one end of the latch 25 is a guide head 28 , and the other end of the latch 25 is provided with a grab plate 29 extending outwards, and the grab plate 29 is arranged at the left end or the right end of the profile bracket 2 .

[0083] In this embodiment, taking the perspective of the attached figure as an example, the guide head is arranged at the left end of the latch, and the guide head is a cone or figure-eight structure with a small left side and a large right side. After the main profile is inserted into the profile positioning groove, it is directly inserted into the bottom positioning groove and the positioning card slot through the guide head. The left end width of the guide head will be less than the sum of the widths of the two. The guide head plays an insertion guide role, which is convenient for the latch to be inserted into the bottom positioning groove and the positioning card slot. At the same time, the setting of the grab plate extends outward, so that the sum of the widths of the latch and the grab plate will be greater than the sum of the widths of the positioning card slot and the bottom positioning groove. After the latch is inserted, the grab plate will be outside the profile bracket (the right end in the attached figure). When it is necessary to disassemble or adjust the main profile, the staff can directly grab the main board and pull the latch away from the profile bracket to achieve rapid disassembly of the latch, thereby facilitating the disassembly or adjustment of the main profile.

[0084] See also Figure 1-4 As shown, at least two positioning slots 24 are respectively provided on the inner wall of each side of the profile positioning slot 21, and the plurality of positioning slots 24 are arranged at intervals from bottom to top. In this embodiment, three positioning slots are respectively provided on the inner wall of each side of the profile positioning slot, which are arranged at intervals from bottom to top, and the corresponding positioning screw holes are connected to the three positioning slots, so that no matter which positioning slot the pin is inserted into, the fastening bolt can hold the pin to limit the main profile.

[0085] In this embodiment, by setting a plurality of positioning slots, during on-site construction, according to the required installation height of the photovoltaic assembly relative to the roof, the bottom positioning slot of the main profile can be adjusted to face the positioning slots at different heights, and then the positioning pins can be inserted into the corresponding positioning slots and the bottom positioning slots, so that the height of the main profile relative to the roof can be adjusted. At the same time, if there is a certain height difference between the roof positions where different photovoltaic mounting bracket assemblies are installed, and the main profile needs to be set as horizontally as possible so that it does not tilt, the height position of the main profile relative to the bottom surface of the profile positioning slot can also be adjusted to ensure that the main profile is as horizontal as possible.

[0086] Therefore, in the present invention, since the main profile needs to be adjusted in height, a bottom positioning groove and multiple positioning slots are used to adjust the height and limit the position, and then a pin is used to limit the main profile. Compared with the method of directly using bolts for limiting the position (no bottom positioning groove is set on the main profile, and no positioning slot is set on the profile bracket, a screw hole is set on the front and back sides of the main profile respectively, and holes at different heights are set on the profile bracket, and bolts are passed through the holes at different positions and the screw holes are screwed together), the contact area between the main profile and the profile bracket can be effectively increased, thereby improving the stability of the entire photovoltaic system, so that the entire photovoltaic system and the roof are subjected to as vertical loads as possible, effectively ensuring the stability of the entire system.

[0087] At the same time, in the present invention, a clamp-type locking structure of a latch is adopted, which is different from the existing screw and T-nut locking structure, and a surface support structure is adopted in the present invention, which can enhance its performance (conventional force modes include point, line, and surface force modes. When the pressure is constant, the larger the force area, the smaller the pressure, and the smaller the effect of the pressure; when the force area is constant, the greater the pressure, the greater the pressure, and the greater the effect of the pressure. Therefore, the surface support force mode is greater than the line support force mode, and also greater than the point force support mode), which greatly protects the force surface area, thereby achieving the effect of protecting the roof system.

[0088] See also Figure 1-3 , 7-9, the photovoltaic positioning member 3 is at least one group, the photovoltaic positioning member is provided with a card plate 321 on the left and / or right side of the top, the card plate 321 is arranged opposite to the main profile 1, and a card plate is arranged on at least one side of the left or right side of the top of the photovoltaic positioning member, a card plate can be arranged on the left side of the top of the photovoltaic positioning member, a card plate can be arranged on the right side of the top of the photovoltaic positioning member, or a card plate can be arranged on the left and right sides of the top of the photovoltaic positioning member, respectively, and the front and rear sides of the bottom of the photovoltaic positioning member 3 are respectively provided with a first clamping member 33 extending toward the outer side and downward;

[0089] The front and rear sides of the top of the main profile 1 are respectively provided with clips 12 extending toward the outer side and downward, each of the clips 12 is clipped and connected to each of the first clips 33, and the photovoltaic positioning component 3 is clipped and installed on the top of the main profile 1 via the first clips 33 and the clips 12.

[0090] In this embodiment, the first clip is a structure with slight elasticity, so when the photovoltaic positioning member and the main profile are installed, the first clip is directly pressed against the top of the main profile, and then downward pressure is applied, so that the first clip is slightly deformed and then automatically recovers after passing through the corresponding clip strip, so that the first clip and the clip strip can be connected. Of course, the first clip can also be a non-elastic structure. When the photovoltaic positioning member and the main profile are installed, the photovoltaic positioning member is first placed at the end of the main profile, and after the first clip is facing the clip strip, the photovoltaic positioning member moves toward the main profile, so that the clip strip is directly inserted into the first clip, and then the photovoltaic positioning member is moved along the main profile, so that the photovoltaic positioning member can be quickly installed.

[0091] In the present invention, the first clamping member 33 includes an inclined plate 331 and a hook 332. The inclined plate is arranged downwardly from the inside to the outside, the inner end of the inclined plate is connected to the side wall of the photovoltaic positioning member, the outer end of the inclined plate is arranged below the outer side of the photovoltaic positioning member, the outer end of the hook is connected to the bottom of the inclined plate, the hook is located on the inner side of the inclined plate, and a clamping groove is formed between the hook and the inclined plate. The clamping groove is a V-shaped structure or an arc structure. The outer side of the clamping strip is arranged parallel to the inclined plate, and the clamping strip is directly inserted into the clamping groove to achieve clamping and limiting of the clamping strip and the first clamping member, thereby preventing the photovoltaic positioning member from moving upward and separating from the main profile. The setting of the clamping plate can use the clamping plate to abut against the top surface of the edge of the photovoltaic assembly to achieve limiting of the photovoltaic assembly and prevent the photovoltaic assembly from moving upward and separating from the main profile. The photovoltaic positioning member is located on the side of the photovoltaic assembly, which can limit the axial movement of the photovoltaic assembly relative to the main profile.

[0092] See also Figure 1-3 As shown in 7-9, the photovoltaic positioning member 3 includes a bottom connecting block 31 and a photovoltaic limiting portion 32, the photovoltaic limiting portion 32 is connected to the bottom connecting block 31 via an adjusting bolt 322, and the two first clamping members 33 are respectively installed on the bottom front side and the rear side of the bottom connecting block 31, the photovoltaic limiting portion 32 is arranged directly above the bottom connecting block 31, and the clamping plate 321 is arranged on the photovoltaic limiting portion 32;

[0093] A connecting screw hole is provided on the top surface of the bottom connecting block 31, 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 arranged between the first clamping parts 33 on both sides, and a clearance hole is provided on the photovoltaic limiting part 32, and the bottom of the adjusting bolt 322 passes through the clearance hole and is connected to the connecting screw hole.

[0094] In this embodiment, the connecting screw hole and the adjusting bolt are arranged so that the photovoltaic positioning member can move axially relative to the main profile after the first clip and the clip strip are clipped. Therefore, when the photovoltaic assembly is installed, the position of the photovoltaic positioning member is slid according to the position of the photovoltaic assembly so that the clip plate is located above the side of the photovoltaic assembly, and then the adjusting bolt is rotated. The screw head of the adjusting bolt will abut against the top surface of the photovoltaic limiting portion. When the adjusting bolt is rotated downward, the photovoltaic limiting portion will be driven to move downward, and the clip plate will abut against the photovoltaic assembly, and the photovoltaic assembly will be pressed against the main profile through the clip plate. At the same time, since the adjusting bolt and the connecting screw hole are screwed together, the bottom connecting block will be subjected to the upward pulling force of the adjusting bolt, driving the bottom connecting block and the first clip to move slightly upward, so that the first clip tightly hooks the clip strip, thereby preventing the bottom connecting block from moving axially relative to the main profile, thereby realizing the limitation of the photovoltaic positioning member and the photovoltaic assembly. Preferably, in this embodiment, the bottom of the adjusting bolt will abut against the top surface of the main profile, further limiting the axial movement of the photovoltaic positioning member relative to the main profile. Thus, by setting the adjusting bolt, it is possible to not only achieve positioning of the photovoltaic positioning member and the main profile, but also install and limit the photovoltaic components.

[0095] See also Figure 1-3 As shown in 7-9, a clamping plate 321 is provided on the photovoltaic limiting portion 32 on one side of the clearance hole, or a clamping plate 321 is provided on the photovoltaic limiting portion 32 on both sides of the clearance hole, and the clamping plate 321 is arranged opposite to the main profile 1.

[0096] In this embodiment, if photovoltaic components need to be installed on both sides of the photovoltaic positioning member, then both sides of the photovoltaic limiting portion are provided with extended card plates, and the photovoltaic components on both sides are limited by the card plates on both sides. If only one side of the photovoltaic positioning member has photovoltaic components that need to be limited, then the photovoltaic limiting portion uses a card plate with an extension on only one side, and the photovoltaic components at the edge can be limited by the card plate. The corresponding photovoltaic limiting portion can be selected according to the actual situation. Among them, in the drawings of this embodiment, two groups of photovoltaic positioning members are installed on the main profile, one group of photovoltaic positioning members has two card plates on it, and the other group of photovoltaic positioning members is provided with a card plate on it.

[0097] Furthermore, in the present invention, the photovoltaic modules are designed according to the roof layout area when they are arranged, so the main profiles will be spliced. Therefore, in this embodiment, a profile connector 13 is also provided, and the middle part of the main profile 1 is provided with a main cavity 14 with two ends passing through, 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 the two ends of the profile connector 13 are respectively inserted into the main cavities 14 of the two adjacent main profiles 1.

[0098] Two adjacent main profiles arranged on the same axis are connected by a profile connector, so that the main profiles arranged in the same row in the entire photovoltaic system form a whole structure, forming an overall structure, so that the main profile can be supported by multiple profile brackets, thereby ensuring that the main profile can stably and firmly support and limit the photovoltaic components.

[0099] Furthermore, in order to ensure that the profile connector plays a limiting role when being installed and connected with the main profile, it is necessary to consider the thermal expansion and contraction between the main profile and the profile connector. Therefore, an outwardly protruding convex portion 15 (a convex portion is shown in the attached figure) is provided on the outer wall of one side of the profile connector 13, and the outer surface of the convex portion 15 and the other outer surfaces of the profile connector 13 are respectively against the inner wall of the main cavity 14. The convex portion is against the inner wall of the main cavity of the main profile, and is fixed on one side, and there is a certain gap between the profile connector and the main profile beside the convex portion, which can be used as a reserved gap for expansion and contraction, which can not only ensure the firmness and stability of the installation, but also meet the deformation requirements of the main profile and the profile connector.

[0100] See also Figure 11-14 As shown, the present invention also provides a photovoltaic system installation structure of a flexible roof with safety properties, including the above-mentioned photovoltaic installation bracket assembly, wherein the photovoltaic installation bracket assembly is a plurality of groups, and the upper part of the plurality of groups of photovoltaic installation bracket assemblies constitutes a photovoltaic assembly installation position;

[0101] A spacing is formed between two adjacent main profiles 1, and a plurality of fire-blocking components 16 are provided in the spacing. A fire partition 17 is formed between adjacent fire-blocking components, and two ends of the fire-blocking components respectively abut against the top surfaces of the main profiles on the adjacent two sides.

[0102] In this way, even if a fire occurs, the fire will be contained in the corresponding fire compartment as much as possible. At the same time, when a fire occurs in a fire compartment, the fire baffles and main profiles can slow down the spread of the fire, thereby providing more sufficient time for rescue and extinguishing the fire, reducing property losses caused by the fire, and reducing safety hazards.

[0103] See also Figure 11-14 As shown, the fire baffle assembly 16 includes at least one fire baffle 18, a connecting plate 19 is provided on the top of the baffle, the two ends of the connecting plate 19 are respectively arranged on both sides of the top of the fire baffle 18, the bottoms of the two ends of the connecting plate 19 are respectively against the top surfaces of the main profiles 1 on the adjacent two sides, the fire baffle 18 is arranged between the adjacent main profiles 1, and the side of the fire baffle 18 is close to or against the side wall of the adjacent main profile 1.

[0104] In the present invention, the fire baffle assembly has a variety of structures. For example, the fire baffle assembly is a fire baffle. The width of the fire baffle is equal to the distance between two adjacent main profiles, or slightly smaller than the distance between the two main profiles. Preferably, the side of the fire baffle abuts against the side wall of the corresponding main profile. The two ends of the connecting plate are outside the two ends of the fire baffle, and the bottom surface of the end of the connecting plate directly abuts against the top surface of the corresponding side main profile, so that the fire baffle is directly placed on the main profile, which is easy to install. Among them, the photovoltaic assembly will be installed on the photovoltaic assembly installation position. Since the photovoltaic assembly is installed above the main profile, it will be above the fire baffle, that is, it will be above the connecting plate, and the fire baffle is limited by the photovoltaic assembly. At the same time, the fire baffle itself has weight, which also plays a limiting role, and due to the presence of the photovoltaic positioning member, it can also limit the movement of the connecting plate on the main profile.

[0105] See also Figure 11-14 As shown, a strip through groove 20 is provided in the middle of the fire baffle 18, and a clearance groove 21 is provided on the fire baffle 18 at both ends of the strip through groove 20, and a limiting plate 22 is provided in the clearance groove 21, and one end of the limiting plate 22 is connected to the top or bottom of the clearance groove 21;

[0106] The fire baffle assembly 16 includes at least two fire baffles 18, the side walls of adjacent fire baffles 18 are in contact, the limiting plates 22 of the fire baffles 18 are inserted into the make way grooves 21 of the adjacent fire baffles 18, and the ends of the connecting plates 19 of the fire baffles 18 at both ends are against the top surfaces of the adjacent main profiles 1.

[0107] In the present invention, due to the different installation conditions of different roofs, the distance between two adjacent main profiles will not be completely consistent with the length of the fire baffle, and the distance between the two main profiles will also be adjusted, some wide, some 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 the present invention, in order to ensure that the end of the fire baffle is close to or against the side wall of the corresponding side main profile, a strip through groove and a limit plate are opened on the fire baffle. In the initial state, the top of the limit plate is connected to the top surface of the clearance groove, the limit plate is in the clearance groove, and there is a spacing between the two sides and the bottom of the limit groove and the clearance groove. Then, according to the spacing between adjacent main profiles, two, three or more fire baffles are directly used for connection. Take the connection of two fire baffles as an example. When connected, the front side of the left fire baffle abuts against the rear side of the right fire baffle, the bottom surface of the connecting plate of the left fire baffle abuts 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, the top of the fire baffle is connected to one side of the bottom of the connecting plate, so the connecting plate can abut against the top surface of the adjacent connecting plate), the left end of the connecting plate of the left fire baffle abuts against the top surface of the left main profile, and the right end of the right connecting plate abuts against the top surface of the right main profile. At the same time, the right end limit plate of the left fire baffle faces the strip groove on the right fire baffle, and then the limit plate is bent and inserted into the strip groove, and then the limit plate is bent again, so that the limit plate becomes a U-shaped structure or a Z-shaped structure. Similarly, the left end limit plate of the right fire baffle is facing the strip groove on the left fire baffle, and the limit plate is inserted into the strip groove of the left fire baffle, and then the limit plate is bent to make the limit plate a U-shaped structure or a Z-shaped structure, see Fig.13 , 14 As shown. The U-shaped or Z-shaped limit plate is inserted into the strip-shaped through groove to connect the adjacent fire baffles, thereby connecting the two fire baffles and adjusting the length of the fire baffle assembly so that the distances between adjacent main profiles are different and the application range is wider.

[0108] At the same time, the bottom of the fire baffle will be above the bottom of the main profile, which will not affect the flow of air and the heat dissipation of the photovoltaic components in the fire partition.

[0109] In the present invention, when the entire photovoltaic system is being constructed, the steps are as follows:

[0110] a. Mark and locate the roof according to the design drawings and confirm the connection and fixing points;

[0111] b. Clean the single-layer roof system and use special tools to make holes on the roof;

[0112] c. Insert the anchor in the photovoltaic installation assembly from the opening to the bottom of the roof. The anchor will automatically flip over. After adjusting the distance between the anchor and the fastening seat, use the construction tool to lock the fastening seat, so as to achieve rapid fixation of the photovoltaic installation assembly and the roof. Then use a hot air welding gun to weld the reserved waterproof skirt of the fastening seat to the roof waterproof layer to achieve waterproof sealing;

[0113] d. Place the profile bracket on the fastening seat and adjust the angle. Lock the top of the profile bracket and the fastening seat with the installation bolts. Place the main profile into the profile positioning slot of the profile bracket. According to the on-site installation height, confirm the installation height of the main profile. Insert the latch for positioning. At the same time, the latch's grip plate should face the ridge. Then, rotate the fastening bolt through the positioning screw hole reserved on the side and tighten the latch.

[0114] e. Install the fire stop assembly on the main profile, and then install the photovoltaic positioning parts on the main profile in turn, and then put in the photovoltaic component (photovoltaic panel). By rotating the adjustment bolts, lock the card of the photovoltaic positioning parts and the photovoltaic component to complete the installation.
