Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0045] The flat roof photovoltaic support is generally fixed in a fixed inclination angle. The fixed photovoltaic support generally adopts the scheme of directly drilling holes on the installation roof and fixing the support with expansion bolts. However, this scheme damages the waterproof layer of the roof system due to drilling, making it difficult to guarantee the secondary waterproofing of the house. At the same time, on-site drilling complicates the support installation process.

[0046] As Figure 1 shown, according to an embodiment of the present utility model, on the one hand, a flat roof photovoltaic ballast support structure is provided, including: a support assembly 1, a connecting assembly 2 and a counterweight 3. Specifically, there are several support assemblies 1; the several support assemblies 1 are evenly spaced; the support assembly 1 is arranged on the roof; the support assembly 1 is adapted to place a photovoltaic module 8; there are several connecting assemblies 2; the connecting assembly 2 is arranged between adjacent support assemblies 1; the several support assemblies 1 are interconnected through the connecting assembly 2; the counterweight 3 is adapted to pass through the interior of the support assembly 1 and is adapted to abut against the support assembly 1; the counterweight 3 fixes the support assembly 1 on the roof by its own weight.

[0047] In this solution, by the way that the counterweight 3 passes through the support assembly 1, the support assembly 1 is firmly fixed on the roof by the weight of the counterweight 3 itself, thus avoiding the problem of damaging the roof waterproof layer due to drilling in the prior art. And this solution also omits steps such as on-site drilling, making the installation process more convenient and increasing the installation efficiency.

[0048] It should be noted that in this embodiment, aluminum alloy material is used. Specifically, both the support assembly 1 and the connection assembly 2 are made of aluminum alloy material. Aluminum alloy material has the characteristics of low density, good mechanical properties, good processing performance, non-toxicity, easy recycling, excellent electrical conductivity, heat transfer performance and corrosion resistance. As an alternative embodiment, steel material can also be used to increase the overall hardness.

[0049] It should be noted that the counterweight 3 is made of a material with a relatively large density, and the weight of the counterweight 3 should ensure that the positions of the support assembly 1 and the connection assembly 2 will not change under the interference of natural external forces.

[0050] In this embodiment, the photovoltaic modules 8 are laid on the support assembly 1. Specifically, one photovoltaic module 8 is supported by every two support assemblies 1, and each photovoltaic module 8 requires four counterweights 3. Specifically, in this embodiment, six support assemblies 1 are arranged in the horizontal direction, and three photovoltaic modules 8 are arranged thereon. Twelve counterweights 3 are arranged inside the support assembly 1.

[0051] It should be noted that in this embodiment, the horizontal direction is the Y direction in the figure, and the vertical direction is the X direction in the figure.

[0052] It should be noted that the support assemblies 1 in this embodiment are evenly spaced in the horizontal direction.

[0053] As Figure 2 shown, in one embodiment, the support assembly 1 includes a bottom beam 101, an inclined beam 102 and an inclined column 103; wherein the bottom beam 101 is arranged on the roof; the first end of the inclined beam 102 is angularly connected to the first end of the bottom beam 101; the photovoltaic module 8 is adapted to be placed on the inclined beam 102; the inclined column 103 is arranged between the bottom beam 101 and the inclined beam 102; the inclined column 103 is adapted to support the inclined beam 102.

[0054] It should be noted that the bottom beam 101, the inclined beam 102 and the inclined column 103 form a triangular frame, and the triangular frame has the best stability. The support assembly 1 is formed in the way of the bottom beam 101, the inclined beam 102 and the inclined column 103, which has the advantages of simple structure and convenient installation.

[0055] In one embodiment, the connection assembly 2 includes a first connecting member and a second connecting member; both ends of the first connecting member are respectively connected to the second ends of two adjacent bottom beams 101; both ends of the second connecting member are respectively connected to the second ends of two adjacent inclined beams 102.

[0056] It should be noted that both the first connecting member and the second connecting member are connected to the bottom beam 101 and the inclined beam 102 by bolts; adjacent support assemblies 1 are connected to each other through the first connecting member and the second connecting member to ensure the stability of the overall structure.

[0057] In one embodiment, the bracket assembly 1 further includes a triangular connecting member 104; the triangular connecting member 104 is disposed between the inclined beam 102 and the bottom beam 101; the inclined beam 102 and the bottom beam 101 are fixedly connected through the triangular connecting member 104. The stability of the connection between the inclined beam 102 and the bottom beam 101 is further increased by the triangular connecting member 104.

[0058] It should be noted that both ends of the inclined column 103 are fixedly connected to the bottom beam 101 and the inclined beam 102 by bolts.

[0059] As Figure 3 shown, in one embodiment, the triangular connecting member 104 includes a triangular plate 1041 and a connecting plate 1042; there are two triangular plates 1041; one side of the triangular plate 1041 is adapted to be fixedly connected to the bottom beam 101 by bolts, and the other side is adapted to be fixedly connected to the inclined beam 102 by bolts; the connecting plate 1042 is disposed between the two triangular plates 1041; the connecting plate 1042 is adapted to connect the two triangular plates 1041.

[0060] It should be noted that the bottom beam 101 is formed by changing a U-shaped plate in this solution. The two ends of the U-shaped plate are bent outward to form a U-shaped, and then the protruding part of the bottom beam 101 is just disposed between the two triangular plates 1041. The bottom of one side triangular plate 1041 is fixedly connected to the bottom beam 101 by two bolts, and the top angle of the triangular plate 1041 is fixedly connected to the inclined beam 102 by one bolt.

[0061] It should be noted that the angle between the bottom beam 101 and the inclined beam 102 is 10 degrees in this embodiment. The angle between the bottom beam 101 and the inclined beam 102 determines the angle between the photovoltaic module 8 and the ground. The angle between the photovoltaic module 8 and the ground is the same as the angle between the bottom beam 101 and the inclined beam 102. The angle between the bottom beam 101 and the inclined beam 102 is reasonably increased or decreased according to actual needs. During actual installation, first fixedly connect the triangular connecting member 104 to the bottom beam 101, then adjust the angle between the bottom beam 101 and the inclined beam 102, and then lock the bolts at the top of the triangular connecting member 104, so as to realize the angle adjustment between the bottom beam 101 and the inclined beam 102.

[0062] In one embodiment, the bracket assembly 1 further includes a ballast beam 4, and the ballast beam 4 is disposed between the counterweight 3 and the bottom beam 101; the ballast beam 4 extends along the length direction of the counterweight 3.

[0063] It should be noted that the ballast beam 4 is fixedly connected to the bottom beam 101 by bolts. In this embodiment, the number of ballast beams 4 is at least one. In this embodiment, there are two of them, and the number can be reasonably adjusted as required; the two ballast beams 4 are arranged near the second end of the bottom beam 101, and the distance between the two ballast beams 4 is 200 mm. The two ballast beams 4 are respectively arranged at the quarter positions of the configuration blocks. Setting the ballast beam 4 can evenly distribute the weight of the counterweight block 3 on the bottom beam 101 and prevent the counterweight block 3 from damaging the bottom beam 101.

[0064] In one embodiment, a wind shield 5 is further included. The wind shield 5 is arranged between two adjacent inclined columns 103. Specifically, the upper end of the wind shield 5 is bent onto the inclined beam 102, and the bending degree is the same as that of the inclined beam 102, and it is fixed to the inclined beam 102 and the inclined column 103 by self-tapping screws.

[0065] It should be noted that by setting the wind shield 5, the lifting force of the wind suction on the photovoltaic module 8 can be reduced. When the natural wind blows from the longitudinal direction, under the action of the wind shield 5, the influence of the wind suction on the photovoltaic module 8 is reduced.

[0066] In one embodiment, a pressing block assembly 6 is further included. One end of the pressing block assembly 6 is fixedly connected to the inclined beam 102, and the other end is adapted to abut against the photovoltaic module 8. The photovoltaic module 8 is fixedly connected to the inclined beam 102 through the pressing block assembly 6, so as to ensure that the position of the photovoltaic module 8 does not change during use and ensure the normal operation of the device. It should be noted that the photovoltaic module 8 is fixedly connected to the inclined beam 102 by abutting, which can avoid damaging the photovoltaic module 8.

[0067] It should be noted that in this embodiment, a groove is provided at the top of the inclined beam 102. The pressing block assembly 6 is an L-shaped plate. One end of the pressing block assembly 6 is fixedly connected to the inclined beam 102 by being clamped with the groove. A bolt hole is provided on the other side of the pressing block, and the pressing block abuts against the photovoltaic module 8 through a bolt with the pressing block assembly 6. The abutting by bolts has the advantage of being easy to disassemble, and the staff can reasonably adjust the abutting force of the bolt on the photovoltaic module 8 according to the on-site environment.

[0068] According to an embodiment of the present invention, on the other hand, a flat roof photovoltaic ballast support system is further provided, including the flat roof photovoltaic ballast support structure described in any one of the above; there are several of the flat roof photovoltaic ballast support structures; adjacent flat roof photovoltaic ballast support structures are connected to each other through a bottom connecting member 7; there are several of the bottom connecting members 7; the end parts of the bottom connecting members 7 are respectively adapted to be fixedly connected to the end parts of the support assembly 1. Specifically, the end parts of the bottom connecting members 7 are respectively adapted to be fixedly connected to the end parts of the bottom beam 101.

[0069] It should be noted that several flat-roof photovoltaic ballast support structures are arranged along the longitudinal direction. In this solution, there are four flat-roof photovoltaic ballast support structures, and the number can be increased or decreased according to actual needs. The flat-roof photovoltaic ballast support structures form an integrated whole connected end to end through the bottom connectors 7.
