Technical Field

[0001] This utility model belongs to the field of photovoltaic bracket technology, specifically relating to a planar FRP photovoltaic bracket. Background Technology

[0002] Solar photovoltaic (PV) mounting brackets are special supports designed for placing, installing, and securing solar panels in a solar photovoltaic power generation system. They are typically made of aluminum alloy, hot-dip galvanized carbon steel, or stainless steel.

[0003] Some flat land or flat roofs do not have the conditions for piling or drilling (for example, piling on soft soil will result in unstable piles that are prone to tilting; drilling holes in the roof will damage the original structure of the roof, causing leaks), thus making it inconvenient to install photovoltaic brackets. Utility Model Content

[0004] This utility model provides a planar FRP photovoltaic unit and photovoltaic bracket, which can still be installed on flat ground or flat roof where piling or drilling is not possible, thus improving the convenience and versatility of photovoltaic bracket installation.

[0006] At least two sets of support seats are spaced apart;

[0007] A column, which is installed on top of the support base;

[0008] A support beam is installed on top of the column.

[0009] Ideally, the support base includes a load-bearing platform and a column base fixed to the top of the load-bearing platform, and the column is detachably inserted into the column base.

[0010] Optimally, the support base further includes a first pad fixed to the bottom of the column base, an installation strip embedded in the load-bearing platform and passing through the first pad, and a clamping nut for locking the first pad to the top of the load-bearing platform.

[0011] Ideally, the support beam is made of FRP material with a strength of not less than 700 MPa and an elastic modulus of not less than 45 GPa.

[0012] Preferably, the column and column base can be made of the same FRP (fiber reinforced polymer) material as the support beam, or they can be made of zinc-magnesium-aluminum alloy or hot-dip galvanized carbon steel.

[0013] This utility model also provides a planar FRP photovoltaic bracket, which includes:

[0014] At least two sets of support components arranged parallel to each other and spaced apart, a support beam mounted on top of the support components, and a locking component for mounting the support beam on top of the support components;

[0015] Each set of the support components includes at least two sets of spaced-apart support seats and a column mounted on top of the support seats, with the support beam mounted on top of the column;

[0016] The angle between the support beam and the column is an acute angle.

[0017] Ideally, the support base includes a load-bearing platform and a column base fixed to the top of the load-bearing platform, and the column is detachably inserted into the column base.

[0018] Ideally, the support beam includes a fixed plate and a support plate integrally connected to the top of the fixed plate and extending to both sides. The support plate is fixed to the side of the column away from the support base, and a photovoltaic panel is fixed to the top of the support plate.

[0019] Optimally, the locking assembly includes a second backing plate mounted on the top of the column, an extension plate integrally connected to the inner side of the second backing plate, and a first backing plate integrally connected between the extension plates, the first backing plate abutting against one side of the fixed plate.

[0020] Ideally, it also includes fasteners for connecting the column.

[0021] Ideally, the fastener is a tie rod fixed between adjacent columns and parallel to each other, and a rib groove formed on the side of the tie rod away from the column.

[0022] Ideally, the fastener is a tie rod fixed to one side of the column and a rib groove formed on the side of the tie rod away from the column.

[0023] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0024] This utility model of a planar FRP photovoltaic bracket uses spaced support components to install support beams, and photovoltaic panels are fixedly installed on the top of the support beams. The photovoltaic bracket can be installed without driving piles on flat ground or drilling holes in flat roofs, making it more versatile and faster and more convenient to install.

[0025] This photovoltaic support system eliminates the need for purlins, reducing installation steps. Photovoltaic modules can be directly bolted to the FRP support beam without the need for clamps, reducing material usage, improving the reliability of module connections, and lowering the risk of module detachment.

[0037] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0038] Example 1

[0039] Figure 1 This is a schematic diagram of the structure of a planar FRP photovoltaic unit according to the present invention. The photovoltaic unit includes a support base, a column 8, and a support beam. There are at least two sets of support bases arranged at intervals, such as... Figure 4As shown, each support group includes a load-bearing platform 1, a first pad 2, an mounting strip 3, a second pad 4, a clamping nut 5, a column base support 6, and a through hole 7. The load-bearing platform 1 is made of cast concrete. The mounting strip 3 is cast together with the load-bearing platform 1 during the casting process to ensure that the mounting strip 3 and the load-bearing platform 1 are an integral structure, thereby improving the structural strength of the mounting strip 3. (The load-bearing platform 1, formed by casting concrete, is more stable when placed on flat ground or the horizontal roof surface of a building due to its large mass. Moreover, the installation process is faster and more convenient, and it will not damage the original structure of the roof.)

[0040] The mounting strip 3 is U-shaped, with its closed side integrally cast with the support platform 1, and its open side extending outside the support platform 1. The open side of the mounting strip 3 is provided with external threads. The first pad 2 is fitted onto the mounting strip 3 and abuts against the upper surface of the support platform 1 (specifically, the first pad 2 has a through hole corresponding to the mounting strip 3, and the diameter of the through hole is slightly larger than the outer diameter of the mounting strip 3).

[0041] The second pad 4 is fitted onto the mounting strip 3 and abuts against the upper surface of the first pad 2 (specifically, the second pad 4 has a through hole 7 corresponding to the mounting strip, and the diameter of the through hole is slightly larger than the outer diameter of the mounting strip 3). There are at least two clamping nuts 5, which are screwed onto the external threads of the mounting strip 3, thereby locking the first pad 2 onto the top of the support platform 1 (by setting the second pad 4, the contact area between the clamping nuts 5 and the support platform 1 is increased, preventing the clamping nuts 5 from loosening and enhancing stability; by setting at least two clamping nuts 5, the mutual counteracting action of the clamping nuts 5 increases the friction between the contact surfaces, thereby preventing the nuts from loosening under force).

[0042] The column base 6 is integrally connected to the top of the first pad 2, and a slot is provided on the top of the column base 6. The through hole 7 penetrates the column base 6 in a horizontal direction (since the slot is provided in the column base 6, the through hole 7 is divided into a first through hole and a second through hole by the slot. The first through hole and the second through hole are coaxially arranged and have the same diameter).

[0043] The vertical cross-sectional shape of the column 8 matches the cross-sectional shape of the slot. During installation, the column 8 is simply inserted into the column base 6. The adjustment hole 9 passes through the column 8 horizontally and mates with the through hole 7. After the column 8 is inserted into the column base 6, the bolt is passed through the through hole 7 and the adjustment hole 9, and a nut is used at the other end to fix the column 8 to the column base 6 (specifically, the bolt passes through the first through hole, the adjustment hole 9 and the second through hole in sequence, and a nut is used at the other end to fix the column 8 to the column base 6).

[0044] The adjustment hole 9 is an oblong hole (i.e., the adjustment hole 9 is a rounded rectangle). The adjustment hole 9 is opened on the column 8, which makes the installation faster and more convenient and avoids the situation of misalignment of the hole due to processing errors.

[0045] The column 8 and column base 6 can be made of the same FRP (fiber reinforced polymer) material as the support beam, or they can be made of zinc-magnesium-aluminum alloy or hot-dip galvanized carbon steel.

[0046] The support beam is fixed to the top of column 8. Figure 6 The front view of the support beam shows a fixed plate 10, a support plate 11, and a protrusion 12. The support plate 11 is integrally connected to the top of the fixed plate 10 and extends to both sides (the support plate 11 and the fixed plate 10 form a "T" shape). The protrusion 12 is integrally connected to both sides of the support plate 11. The protrusion 12 and the fixed plate 10 are located on the same side of the support plate 11. The protrusion 12 protects the support plate 11, ensuring its flatness and preventing it from bending and affecting the installation of subsequent photovoltaic panels.

[0047] The support beam is made of FRP material with a strength of not less than 700MPa and an elastic modulus of not less than 45GPa. The FRP support beam is corrosion resistant and also resistant to typhoon impact.

[0048] The locking assembly is used to secure the support beam to column 8, such as... Figure 5 , 7 As shown, the locking assembly includes a first backing plate 13, an extension plate 14, a second backing plate 15, a fastening bolt 16, a first washer 17, a second washer 18, and a fastening nut 19. The second backing plate 15 is installed on the top of the column 8 by bolt fastening. The extension plate 14 is integrally connected to the inner side of the second backing plate 15, and the extension plate 14 and the second backing plate 15 are in an "L" shape. The first backing plate 13 is integrally connected between the extension plates 14 to improve the structural strength of the extension plates 14 and prevent the extension plates 14 from bending under pressure.

[0049] The first backing plate 13 and the extension plate 14 form a "U" shape, and the first backing plate 13 abuts against one side of the fixed plate 10 of the support beam. In actual installation, the second backing plate 15 is fixed to the top of the column 8, and the first backing plate 13 abuts against one side of the fixed plate 10 of the support beam (through holes are opened at corresponding positions of the first backing plate 13 and the fixed plate 10. After the first backing plate 13 abuts against one side of the fixed plate 10, the bolt is passed through the through holes of the first backing plate 13 and the fixed plate 10, and the other end is nutped to complete the fixation of the first backing plate 13 and the fixed plate 10).

[0050] Figure 2 This is the front view of the photovoltaic bracket of this utility model. Figure 3 This is a top view of the photovoltaic support structure of this utility model. The photovoltaic support structure includes support components, support beams, and locking components. The support components are typically installed on the horizontal roof surface of a building, and there are at least two sets of support components arranged at intervals to support the photovoltaic panels above.

[0051] The support beam is installed on top of the support assembly, such as... Figure 1 , 2 As shown, the support beam is tilted, meaning the angle between the support beam and the support assembly is an acute angle α (0°<α≤50°). The locking assembly is used to fix the support beam to the top of the support assembly. The tilted photovoltaic panel can better capture sunlight, thereby improving power generation efficiency.

[0052] Each set of support components includes at least two sets of support seats spaced apart and a column 8 installed on top of the support seats. Therefore, each photovoltaic panel is supported by at least four sets of support seats, and the four sets of support seats are located at the four corners of the photovoltaic panel to improve the stability of the photovoltaic panel installation.

[0053] like Figure 4 As shown, each support group includes a load-bearing platform 1, a first pad 2, an mounting strip 3, a second pad 4, a clamping nut 5, a column base support 6, and a through hole 7. The load-bearing platform 1 is made of cast concrete. The mounting strip 3 is cast together with the load-bearing platform 1 during the casting process to ensure that the mounting strip 3 and the load-bearing platform 1 are an integral structure, thereby improving the structural strength of the mounting strip 3. (The load-bearing platform 1, formed by casting concrete, is more stable when placed on flat ground or the horizontal roof surface of a building due to its large mass. Moreover, the installation process is faster and more convenient, and it will not damage the original structure of the roof.)

[0054] The mounting strip 3 is U-shaped, with its closed side integrally cast with the support platform 1, and its open side extending outside the support platform 1. The open side of the mounting strip 3 is provided with external threads. The first pad 2 is fitted onto the mounting strip 3 and abuts against the upper surface of the support platform 1 (specifically, the first pad 2 has a through hole corresponding to the mounting strip 3, and the diameter of the through hole is slightly larger than the outer diameter of the mounting strip 3).

[0055] The second pad 4 is fitted onto the mounting strip 3 and abuts against the upper surface of the first pad 2 (specifically, the second pad 4 has a through hole 7 corresponding to the mounting strip, and the diameter of the through hole is slightly larger than the outer diameter of the mounting strip 3). There are at least two clamping nuts 5, which are screwed onto the external threads of the mounting strip 3, thereby locking the first pad 2 onto the top of the support platform 1, preventing the column base 6 from shaking when installing the photovoltaic panel (by setting the second pad 4, the contact area between the clamping nut 5 and the support platform 1 is increased, preventing the clamping nut 5 from loosening and enhancing stability; by setting at least two clamping nuts 5, the mutual counteracting action of the clamping nuts 5 increases the friction between the contact surfaces, thereby preventing the nuts from loosening under force).

[0056] The column base 6 is integrally connected to the top of the first pad 2, and a slot is provided on the top of the column base 6. The through hole 7 penetrates the column base 6 in a horizontal direction (since the slot is provided in the column base 6, the through hole 7 is divided into a first through hole and a second through hole by the slot. The first through hole and the second through hole are coaxially arranged and have the same diameter).

[0057] The vertical cross-sectional shape of the column 8 matches the cross-sectional shape of the slot. During installation, the column 8 is simply inserted into the column base 6. The adjustment hole 9 passes through the column 8 horizontally and mates with the through hole 7. After the column 8 is inserted into the column base 6, the bolt is passed through the through hole 7 and the adjustment hole 9, and a nut is used at the other end to fix the column 8 to the column base 6 (specifically, the bolt passes through the first through hole, the adjustment hole 9 and the second through hole in sequence, and a nut is used at the other end to fix the column 8 to the column base 6).

[0058] The adjustment hole 9 is an oblong hole (i.e., the adjustment hole 9 is a rounded rectangle). The adjustment hole 9 is opened on the column 8, which makes the installation faster and more convenient and avoids the situation of misalignment of the hole due to processing errors.

[0059] The support beam is fixed to the top of column 8. Figure 6 The front view of the support beam shows a fixed plate 10, a support plate 11, and a protrusion 12. The support plate 11 is integrally connected to the top of the fixed plate 10 and extends to both sides (the support plate 11 and the fixed plate 10 form a "T" shape). The protrusion 12 is integrally connected to both sides of the support plate 11. The protrusion 12 and the fixed plate 10 are located on the same side of the support plate 11. The protrusion 12 protects the support plate 11, ensuring its flatness and preventing it from bending and affecting the installation of the photovoltaic panels above.

[0060] The locking assembly is used to secure the support beam to column 8, such as... Figure 5 , 7 As shown, the locking assembly includes a first backing plate 13, an extension plate 14, a second backing plate 15, a fastening bolt 16, a first washer 17, a second washer 18, and a fastening nut 19. The second backing plate 15 is installed on the top of the column 8 by bolt fastening. The extension plate 14 is integrally connected to the inner side of the second backing plate 15, and the extension plate 14 and the second backing plate 15 are in an "L" shape. The first backing plate 13 is integrally connected between the extension plates 14 to improve the structural strength of the extension plates 14 and prevent the extension plates 14 from bending under pressure.

[0061] The first backing plate 13 and the extension plate 14 form a "U" shape, and the first backing plate 13 abuts against one side of the fixed plate 10 of the support beam. In actual installation, the second backing plate 15 is fixed to the top of the column 8, and the first backing plate 13 abuts against one side of the fixed plate 10 of the support beam (through holes are opened at corresponding positions of the first backing plate 13 and the fixed plate 10. After the first backing plate 13 abuts against one side of the fixed plate 10, the bolt is passed through the through holes of the first backing plate 13 and the fixed plate 10, and the other end is nutped to complete the fixation of the first backing plate 13 and the fixed plate 10).

[0062] Finally, the photovoltaic panel is installed on the support plate 11 of the support beam (the support plate 11 has through holes, and the bolts are passed through the side through holes of the photovoltaic panel and the through holes of the support plate 11, and the other end is nutted to complete the installation of the photovoltaic panel).

[0063] Fasteners are fixed between the columns 8 to improve the structural strength of the columns 8. In this embodiment, the fasteners are tie rods 20 and rib grooves 21. Figure 8 As shown, the tie rod 20 is located on one side of the column 8, and the rib groove 21 is formed on the side of the tie rod 20 away from the column 8. Bolts pass through the tie rod 20 and are fixed to the column 8, thereby improving the structural strength of the column 8.

[0064] Since the tie rod 20 is horizontally positioned and the bolt head is located inside the rib groove 21, the built-in bolt head design can protect the bolt and prevent rainwater from falling on it and causing it to rust.

[0065] Example 2

[0066] The technical solution of Embodiment 2 is basically the same as that of Embodiment 1, the only difference being the fastener installation method. Figure 9 The diagram shown is a structural schematic of the fastener in Embodiment 2. In this embodiment, the tie rod 20 is fixed at an angle to one side of two adjacent columns 8, and the tie rods 20 are parallel to each other (the angle between the tie rod 20 and the horizontal ground or horizontal roof is 20°-45°).

[0067] Because the tie rod 20 is tilted, rainwater falling into the rib groove 21 will flow downward along the tilted tie rod 20, preventing rainwater from accumulating in the rib groove 21 and causing the bolts to rust.

[0068] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
