[0001] The embodiments in this application relate to the field of photovoltaic equipment technology, and in particular to a photovoltaic module mounting bracket. Background Technology

[0002] In related technologies, when constructing a photovoltaic system on a building roof, the bracket is usually connected to the roof wall of the building by passing through the overlapping joints of the tiles, and the bracket is bent above the tiles to accommodate the arrangement and installation of the photovoltaic modules.

[0003] However, when subjected to loads, the aforementioned supports are prone to generating lateral forces and bending moments on the building roof, which can easily lead to damage to the roof's insulation and waterproofing layers, reducing the practicality and reliability of the supports. Utility Model Content

[0004] Several embodiments in this application propose a photovoltaic module mounting bracket, which aims to improve the practicality and structural reliability of the photovoltaic module mounting bracket.

[0005] One embodiment of this application proposes a photovoltaic module mounting bracket including a bracket body, a load-bearing body, and anchors. The bracket body includes a base plate and a column. The column is connected to the base plate, and the base plate is provided with an anchor plate segment surrounding the column. The load-bearing body is connected to the end of the column away from the base plate and is used to connect the photovoltaic support structure. The anchors are connected to the anchor plate segment and are used to fix the connection to the building roof.

[0006] In one embodiment, the column includes a first column and a second column coaxially connected, the first column being connected to the base plate, the supporting body being connected to the second column, and the outer diameter of the first column being larger than the outer diameter of the second column.

[0007] In one embodiment, the outer diameter of the first column gradually decreases from the base plate to the second column.

[0008] In one embodiment, the photovoltaic module mounting bracket further includes a sealing ring, which is fitted around the outer periphery of the column, and the sealing element is used to fill the gap between the column and the tile clearance hole.

[0009] In one embodiment, the photovoltaic module mounting bracket further includes a clamping block, which is sleeved on the outer periphery of the column and threadedly connected to the outer periphery of the column. The clamping block is located on the side of the sealing ring away from the base plate and presses against the sealing ring.

[0010] In one embodiment, the clamping block is provided with a pressing conical hole, and the sealing ring is provided with a conical protrusion on the side away from the base plate, the conical protrusion being inserted into the pressing conical hole.

[0011] In one embodiment, the sealing ring is threadedly connected to the outer periphery of the column.

[0012] In one embodiment, the column is provided with a connecting hole, which extends coaxially with the column; the supporting body includes a support rod and a support base, the support rod is inserted into the connecting hole, and the periphery of the support rod is threadedly connected to the inner wall of the connecting hole; the support rod and the column are axially movable relative to each other; the support base is connected to the end of the support rod away from the base plate, and the support base is used to connect the photovoltaic support structure.

[0013] In one embodiment, the supporting body further includes a locking nut, which is sleeved on the outer periphery of the support rod and threadedly connected to the outer periphery of the support rod. The locking nut presses against the end face of the column away from the base plate.

[0014] In one embodiment, the support base is provided with a first mounting hole, which extends coaxially with the support rod; and / or, the support base includes a central portion and a surrounding plate portion, the support rod is connected to the central portion, the surrounding plate portion is disposed around the central portion, and the surrounding plate portion is provided with at least one second mounting hole.

[0015] In the various embodiments provided in this application, the main body of the bracket is set with a base plate and columns connected to the base plate, and a load-bearing body is connected to the top of the column to support the photovoltaic support structure such as purlins and square steel. This allows the photovoltaic module mounting bracket to adopt a column-type centrally symmetrical structure design. By opening small clearance holes in the tiles for the columns to pass through, the photovoltaic module mounting bracket can be arranged on the building roof according to the arrangement requirements of the photovoltaic modules. Compared to installing the bracket at the overlap of the tiles and bending it on the tile surface to accommodate the arrangement of photovoltaic modules, the technical solution of this application utilizes smaller columns vertically inserted through the tiles. This allows the mounting bracket to transfer the load force to the building roof axially, effectively reducing the lateral and bending moment forces on the mounting bracket. It also prevents the anchors from prying up the waterproof and insulation layers of the building roof, and eliminates the need to cut grooves on the building surface for mounting bracket assembly. This significantly reduces the construction steps for photovoltaic module mounting brackets, lowers construction difficulty and time, and better ensures the waterproof and insulation performance of the building roof, further improving the practicality and structural reliability of the photovoltaic module mounting bracket.

[0033] In related technologies, when constructing photovoltaic systems on building roofs, the brackets are mostly connected to the roof walls by passing through the overlap gaps of the tiles, and then bent above the tiles to accommodate the arrangement and installation of the photovoltaic modules. However, when subjected to loads, these brackets are prone to generating lateral forces and bending moments on the building roof, which can easily damage the roof's insulation and waterproofing layers, reducing the practicality and reliability of the brackets.

[0034] It is understandable that, such as Figure 1 As shown, the photovoltaic support 900, which is bent and installed above the roof tiles 600, connects to the roof at the overlap of the roof tiles 600. When supporting the photovoltaic modules 400, the load force G1 on the support 900 is not on the same line as the supporting force F1 from the roof. This can easily generate a certain lateral force P1 and bending moment P2 at the connection between the support 900 and the roof. Therefore, a more stable anchoring method is needed to prevent the support 900 from detaching from the roof under stress. Furthermore, since the roof surface is usually composed of a waterproof layer 81 and a heat insulation layer 83, the structural strength of these layers is lower than that of the internal wall structure layer 85. When the support 900 is subjected to the lateral force P1 and bending moment P2, it is easy to pry over the waterproof layer 81 and the heat insulation layer 83, thus detaching it from the roof. Therefore, in most existing technologies, clearance grooves 87 are created on the surface of the building roof to allow the bracket 900 to be placed into the clearance grooves 87 and connected to the structural layer 85 of the building roof wall, preventing the bracket 900 from loosening and allowing it to be more stably anchored on the building roof. However, this arrangement makes the assembly of the photovoltaic system bracket 900 more complicated and also compromises the integrity of the waterproof layer 81 and the heat insulation layer 83 of the building roof. To address the above problems, this application proposes a photovoltaic module mounting bracket 100.

[0035] Please see Figure 2 , Figure 4 and Figure 7 In one embodiment of this application, the photovoltaic module mounting bracket 100 includes a bracket body 10, a load-bearing body 30, and an anchor 50. The bracket body 10 includes a base plate 11 and a column 13. The column 13 is connected to the base plate 11, and the base plate 11 is provided with an anchor plate segment 111 surrounding the column 13. The load-bearing body 30 is connected to the end of the column 13 away from the base plate 11, and the load-bearing body 30 is used to connect the photovoltaic support structure 200. The anchor 50 is connected to the anchor plate segment 111 and is used to fix and connect to the building roof.

[0036] In this application, the photovoltaic module mounting bracket 100 can be installed and constructed on the roof of a building as follows: Figures 3 to 6As shown, the base plate 11 can be placed at the corresponding installation position on the building roof. By providing an anchor plate segment 111 around the column 13, the base plate 11 can be constructed with a larger sheet metal structure, which helps to reduce the pressure on the building roof when the mounting bracket is subjected to the load of the photovoltaic module 400. The anchor 50 can be a long bolt, expansion bolt, or other fastening structure, which is used to fix the anchor plate segment 111 to the building roof, ensuring the stable installation of the mounting bracket on the building roof.

[0037] By setting up columns 13 on the base plate 11, and using the load-bearing body 30 connected to the top of the columns 13 to connect and install the photovoltaic support structure 200 such as purlins and square steel, the load-bearing body 30 can be a plate structure with a certain load-bearing area, so that the load-bearing body 30 can stably support the photovoltaic support structure 200. The photovoltaic modules 400 can then be fixedly installed on the photovoltaic support structure 200, ensuring stable support of the photovoltaic modules 400 by the mounting bracket. Thus, as... Figure 2 As shown, the bracket body 10 is formed by the base plate 11 and the column 13. The bracket can adopt a centrally symmetrical structure design with column 13. When the photovoltaic module mounting bracket 100 carries the photovoltaic module 400, the load force G2 on the photovoltaic module mounting bracket 100 and the supporting force F2 from the building roof can be on the same straight line. This allows the load on the photovoltaic module mounting bracket 100 to be transferred axially to the building roof, effectively reducing the lateral force and bending moment on the mounting bracket. This effectively prevents the anchor 50 from prying over the waterproof layer 81 and the heat insulation layer 83 of the building roof, eliminating the need to cut grooves in the building roof for the mounting bracket to anchor, and effectively reducing the assembly difficulty of the photovoltaic module mounting bracket 100.

[0038] Furthermore, by setting up columns 13 on the base plate 11 to connect the supporting body 30, when the roof tiles 600 are laid out, the columns 13 can be inserted through small clearance holes 60 on the tiles 600, allowing the mounting bracket to stably avoid the arrangement of the tiles 600. This eliminates the need to install the mounting bracket to match the overlap gap of the tiles 600, allowing the mounting bracket to better match the arrangement requirements of the photovoltaic modules 400. It also eliminates the need for bending structures on the tile surface to meet the installation requirements of the photovoltaic modules 400, enabling the photovoltaic module mounting bracket 100 to better achieve the symmetrical structure design of the columns 13, further reducing the anchoring connection requirements between the anchors 50 and the roof, facilitating the overall assembly of the photovoltaic module mounting bracket 100, and further improving the practicality and structural reliability of the photovoltaic module mounting bracket 100.

[0039] In one embodiment of this application, by using a base plate 11 and a column 13 connected to the base plate 11 for the support body 10, and connecting a load-bearing body 30 at the top of the column 13 to support the photovoltaic support structure 200 such as purlins and square steel, the photovoltaic module mounting bracket 100 can adopt a centrally symmetrical structure design with a column 13. By opening a small clearance hole 60 on the tile 600 for the column 13 to pass through, the photovoltaic module mounting bracket 100 can be arranged on the building roof according to the arrangement requirements of the photovoltaic modules 400. Compared to installing the bracket at the overlap of the tile 600 and bending the bracket on the surface of the tile 600 to accommodate the arrangement of the photovoltaic module 400, the technical solution of this application can use smaller columns 13 to vertically penetrate the tile 600, allowing the mounting bracket to transfer the load force to the building roof along the axial direction. This effectively reduces the lateral force and bending moment on the mounting bracket, prevents the anchor 50 from prying over the waterproof layer 81 and heat insulation layer 83 of the building roof, and eliminates the need to cut grooves on the building surface for mounting bracket assembly. This significantly reduces the construction steps of the photovoltaic module mounting bracket 100, lowers the construction difficulty and construction cycle, and better ensures the waterproof and heat insulation performance of the building roof, further improving the practicality and structural reliability of the photovoltaic module mounting bracket 100.

[0040] See Figure 7 In one embodiment of this application, the column 13 includes a first column 131 and a second column 133 coaxially connected. The first column 131 is connected to the base plate 11, and the supporting body 30 is connected to the second column 133. The outer diameter of the first column 131 is larger than the outer diameter of the second column 133.

[0041] In this embodiment, by adopting a segmented column structure design with a certain difference in outer diameter, the column 13 can be connected to the base plate 11 using the first column 131 with a larger outer diameter to form a base structure with better overall stability, thus achieving a more reliable anchoring support for the mounting bracket. At the same time, by using the first column 131 with a larger outer diameter to ensure that the column 13 is stably installed on the building roof, a smaller second column 133 can be used to pass through the tile 600. This allows the tile 600 to have a smaller clearance hole 60 for the second column 133 to pass through, which helps to reduce the difficulty of drilling holes in the tile 600, reduce the overall construction difficulty of the photovoltaic module mounting bracket 100, and further improve the practicality and structural reliability of the photovoltaic module mounting bracket 100.

[0042] In some embodiments, the outer diameter of the first column 131 can be gradually reduced from the base plate 11 to the second column 133, so that the first column 131 forms a cone-like structural design. This allows the column 13 to transmit the load force to the base plate 11 more smoothly, reducing the risk of breakage at the connection between the first column 131 and the second column 133, and achieving better overall structural stability of the photovoltaic module mounting bracket 100.

[0043] In one embodiment of this application, the anchor 50 is a chemical bolt.

[0044] It should be noted that chemical bolts can consist of a chemical hose, a screw, a washer, and a nut. The screw, washer, and nut (hexagonal) are generally made of galvanized steel or stainless steel (hot-dip galvanizing is also possible upon request). The chemical hose (or a plastic-packaged chemical tube) contains reactive resin, a curing agent, and quartz particles. Using chemical bolts to connect the base plate 11 to the building roof allows the chemical bolts to pass through the roof's waterproof layer 81, insulation layer 83, and structural layer 85. At this point, the chemical hose surrounding the screw can bond the screw to the structural layer 85, forming a unified structure between the chemical bolt and the building wall, thereby achieving the effect of fixing the base plate 11 or increasing its load-bearing capacity.

[0045] The base plate 11 can have openings in the anchor plate section 111 for the screw to pass through, so that the screw can pass through the openings and be inserted and fixed in the wall of the building roof. At the same time, the nut connected to the thread on the screw presses against the surface of the base plate 11, so that the anchor 50 can stably anchor the base plate 11 to the building roof, ensuring the stable support of the photovoltaic module mounting bracket 100 for the photovoltaic module 400, and further improving the structural stability and reliability of the photovoltaic module mounting bracket 100.

[0046] See Figure 4 \ Figure 6 and Figure 8 In one embodiment of this application, the photovoltaic module mounting bracket 100 further includes a sealing ring 70, which is sleeved on the outer periphery of the column 13 and is used to fill the gap between the column 13 and the clearance hole 60 of the tile 600.

[0047] By creating clearance holes 60 in the tile 600 for the column 13 to pass through, a certain gap may exist between the inner wall of the clearance hole 60 and the outer periphery of the column 13, potentially leading to a water leakage risk. In this embodiment, a sealing ring 70 is fitted around the periphery of the column 13. The sealing ring 70 can be made of elastic materials such as silicone or rubber. The elastic deformation of the sealing ring 70 can stably fill the gap between the column 13 and the clearance hole 60 of the tile 600, effectively preventing rainwater and other impurities from passing through the gap between the column 13 and the clearance hole 60, thus avoiding water accumulation on the building roof and further improving the practicality and structural reliability of the photovoltaic module mounting bracket 100.

[0048] See Figure 6 , Figure 8 and Figure 9 In one embodiment of this application, the photovoltaic module mounting bracket 100 further includes a clamping block 90, which is sleeved on the outer periphery of the column 13 and threadedly connected to the outer periphery of the column 13. The clamping block 90 is located on the side of the sealing ring 70 away from the base plate 11 and presses against the sealing ring 70.

[0049] In this embodiment, the outer periphery of the column 13 may be provided with external threads, and the clamping block 90 may be a block structure with a through hole in the center. An internal thread that mates with the external threads on the outer periphery of the column 13 may be provided on the inner wall of the through hole of the clamping block 90, so that the clamping block 90 and the column 13 are connected by thread engagement. This allows the clamping block 90 to be securely installed on the column 13, so that the clamping block 90 presses against and fixes the sealing ring 70, preventing the sealing ring 70 from coming out of the gap between the column 13 and the tile 600 clearance hole 60. This ensures the stable sealing and waterproofing effect of the sealing ring 70 between the column 13 and the tile 600 clearance hole 60, and further improves the structural stability and reliability of the photovoltaic module mounting bracket 100.

[0050] The outer periphery of the clamping block 90 can be provided with a square or polygonal rim, or anti-slip protrusions can be provided on the outer periphery of the clamping block 90, so that the construction personnel can hold the clamping block 90 more stably and rotate it on the column 13, so as to better tighten the clamping block 90 on the column 13, and enable the clamping block 90 to stably press against the fixed sealing ring 70, further improving the operational convenience and practicality of the photovoltaic module mounting bracket 100.

[0051] See Figure 9 and Figure 10 In one embodiment of this application, the clamping block 90 is provided with a pressing conical hole 91, and the sealing ring 70 is provided with a conical protrusion 71 on the side away from the base plate 11, and the conical protrusion 71 is inserted into the pressing conical hole 91.

[0052] In this embodiment, the end of the pressing block 90 facing the sealing ring 70 may be provided with a pressing tapered hole 91 extending from the sealing ring 70 to the bearing body 30. The inner diameter of the pressing tapered hole 91 may be gradually reduced from the sealing ring 70 to the bearing body 30. By providing a tapered protrusion 71 at the end of the sealing ring 70 away from the base plate 11, the outer diameter of the tapered protrusion 71 can be gradually reduced from the base plate 11 to the bearing body 30. By matching the shape of the tapered protrusion 71 with the shape of the pressing tapered hole 91, the tapered protrusion 71 can be inserted into the pressing tapered hole 91 when the pressing block 90 presses against and fixes the sealing ring 70. The inner wall of the pressing tapered hole 91 abuts against the outer wall of the tapered protrusion 71, which helps to increase the contact area between the pressing block 90 and the sealing ring 70, increase the pressing effect of the pressing block 90 on the sealing ring 70, better prevent the sealing ring 70 from dislodging from the gap between the column 13 and the clearance hole 60, achieve a better sealing and waterproof effect, and further improve the structural stability and reliability of the photovoltaic module mounting bracket 100.

[0053] In one embodiment of this application, the sealing ring 70 is threadedly connected to the outer periphery of the column 13.

[0054] In this embodiment, the outer periphery of the column 13 may be provided with external threads, and the sealing ring 70 may be provided with a through hole. An internal thread that matches the external threads on the outer periphery of the column 13 may be provided on the inner wall of the through hole, so that the sealing ring 70 can be installed on the outer periphery of the column 13 through thread engagement. The thread fastening effect ensures that the sealing ring 70 is firmly installed on the column 13, effectively preventing the sealing ring 70 from shifting axially on the column 13, ensuring that the sealing ring 70 is stably filled in the gap between the column 13 and the clearance hole 60, achieving a more stable and reliable sealing and waterproofing effect, and further improving the structural stability and reliability of the photovoltaic module mounting bracket 100.

[0055] See Figure 8 , Figure 9 and Figure 11 In one embodiment of this application, the column 13 is provided with a connecting hole 135, which extends coaxially with the column 13; the supporting body 30 includes a support rod 31 and a support base 33, the support rod 31 is inserted into the connecting hole 135, the periphery of the support rod 31 is threadedly connected to the inner wall of the connecting hole 135, and the support rod 31 and the column 13 are axially movable relative to each other; the support base 33 is connected to the end of the support rod 31 away from the base plate 11, and the support base 33 is used to connect the photovoltaic support structure 200.

[0056] In this embodiment, by providing a coaxially extending connecting hole 135 on the column 13, an internal thread can be provided on the inner wall of the connecting hole 135. At this time, by providing a support rod 31 coaxially extending from the column 13 on the bearing body 30, an external thread matching the internal thread of the connecting hole 135 can be provided on the outer periphery of the support rod 31. By connecting the external thread on the outer periphery of the support rod 31 with the internal thread on the inner wall of the connecting hole 135, the support rod 31 can be fixedly inserted into the connecting hole 135 by the thread. Furthermore, by rotating the thread, the support rod 31 and the column 13 can be moved relative to each other along the axial direction, thereby realizing the height adjustment design of the support rod 31 on the column 13.

[0057] Furthermore, by including a support rod 31 and a support base 33 in the main support body 30, the threaded connection between the support rod 31 and the connecting hole 135 allows the support rod 31 to be adjusted to any height above the column 13. This facilitates adjusting the overall height of the photovoltaic module mounting bracket 100, enabling the photovoltaic module mounting bracket 100 to accommodate various tilt angles for the photovoltaic module 400. This allows the photovoltaic module 400 to better adapt to the light source incident angle arrangement of the installation environment, improving the light energy conversion efficiency of the photovoltaic system. The support base 33 connected to the end of the support rod 31 supports and fixes the photovoltaic support structure 200, such as purlins and square steel. A larger support base 33 can ensure stable support for the photovoltaic support structure 200, allowing the photovoltaic module mounting bracket 100 to more stably support the photovoltaic module 400, further improving the overall structural stability and reliability of the photovoltaic module mounting bracket 100.

[0058] See Figures 7 to 9 In one embodiment of this application, the supporting body 30 further includes a locking nut 35, which is sleeved on the outer periphery of the support rod 31 and threadedly connected to the outer periphery of the support rod 31. The locking nut 35 presses against the end face of the column 13 away from the base plate 11.

[0059] In this embodiment, the locking nut 35 may have a threaded hole in the middle that mates with the external thread of the support rod 31. The locking nut 35 is sleeved on the support rod 31, and the internal thread of the threaded hole engages with the external thread of the support rod 31, thus fixing the locking nut 35 on the support rod 31. This allows the locking nut 35 to change its position on the support rod 31 as the support rod 31 moves relative to the column 13. The locking nut 35 presses against the end face of the column 13 away from the base plate 11, effectively preventing axial displacement between the support rod 31 and the column 13. This allows for height adjustment and fixation of the column 13 and the support rod 31, enabling the photovoltaic module mounting bracket 100 to more stably support the photovoltaic module 400, further improving the overall structural stability and reliability of the photovoltaic module mounting bracket 100.

[0060] The locking nut 35 can be provided with a square or polygonal rim, or anti-slip protrusions can be provided on the outer periphery of the locking nut 35, so that the construction personnel can hold the locking nut 35 more stably and rotate it on the support rod 31, so as to better tighten the locking nut 35 on the support rod 31, and enable the locking nut 35 to stably press against the end face of the column 13, further improving the operation convenience and practicality of the photovoltaic module mounting bracket 100.

[0061] See Figures 6 to 8 In one embodiment of this application, the support base 33 is provided with a first mounting hole 3311, which extends coaxially with the support rod 31; and / or, the support base 33 includes a central portion 331 and a surrounding plate portion 333, the support rod 31 is connected to the central portion 331, the surrounding plate portion 333 is disposed around the central portion 331, and the surrounding plate portion 333 is provided with at least one second mounting hole 3331.

[0062] In some embodiments, by providing a first mounting hole 3311 on the support base 33 that extends coaxially with the support rod 31, the photovoltaic support structure 200 can be fastened by inserting fasteners such as screws and pins, and the fasteners can be fixed in the first mounting hole 3311 to fix the photovoltaic support structure 200 on the support base 33. In this way, the load force on the photovoltaic module mounting bracket 100 can be better transferred axially to the wall of the building roof, and the lateral force and bending moment force on the photovoltaic module mounting bracket 100 can be better reduced, thereby further improving the structural stability and reliability of the photovoltaic module mounting bracket 100.

[0063] Furthermore, in some embodiments, the support base 33 can be connected to the support rod 31 via its central portion 331, and an outwardly extending surrounding plate portion 333 is provided around the central portion 331. By using the surrounding plate portion 333 to surround the central portion 331, the load-bearing area of ​​the support base 33 can be increased, ensuring the stable support function of the support base 33. In this case, by providing at least one second mounting hole 3331 on the surrounding plate portion 333, the photovoltaic support structure 200 can be fastened by inserting fasteners such as screws and pins, and the fasteners can be fixed in the second mounting hole 3331 to fix the photovoltaic support structure 200 on the support base 33. By providing at least one second mounting hole 3331 on the larger enclosure 333 for the photovoltaic support structure 200 to be installed and connected, the number of installation connection points of the photovoltaic support structure 200 on the support base 33 can be increased, and the installation position of the photovoltaic support structure 200 and the load-bearing body 30 can be finely adjusted so that the photovoltaic module mounting bracket 100 can better match the arrangement requirements of the photovoltaic module 400, and further improve the practicality and structural reliability of the photovoltaic module mounting bracket 100.

[0064] In other embodiments, the support base 33 may have a first mounting hole 3311 extending coaxially with the support rod 31 in its central part 331, and at least one second mounting hole 3331 in its surrounding plate part 333. In this way, when the photovoltaic support structure 200 is assembled on the support base 33, the photovoltaic support structure 200 can be fastened to the first mounting hole 3311 or the second mounting hole 3331 using fasteners according to the installation position requirements of the photovoltaic support structure 200. This allows the photovoltaic module mounting bracket 100 to better meet the installation and arrangement requirements of the photovoltaic module 400, ensure the stable support of the photovoltaic module mounting bracket 100 for the photovoltaic module 400, and further improve the practicality and structural reliability of the photovoltaic module mounting bracket 100.
