However, due to the diversity of enterprise production, the roof forms have also become diversified. Among them, TPO (thermoplastic polyolefin) waterproof coiled materials are increasingly used for factory building roofs due to their excellent waterproofness, weather resistance, high elasticity, and durability. When designing a photovoltaic bracket on this basis, in order to prevent the photovoltaic bracket from "conflicting" with the original lightning protection and grounding system on the roof, and at the same time to reserve space for later roof maintenance and photovoltaic operation and maintenance, it is necessary to leave enough space between the photovoltaic bracket and the roof during design. However, due to the particularity of the TPO roof photovoltaic bracket, when the bracket is too high, the stability of the photovoltaic array will be greatly reduced and large displacements will occur. Therefore, there is an urgent need to solve a diagonal tension support structure that can limit the displacement of the bracket and improve the overall stability of the photovoltaic array.

[0025] As Figure 1 、 Figure 2 and Figure 3 shown, the present invention provides a TPO roof photovoltaic bracket screw diagonal bracing. The diagonal bracing includes an upper tie rod 1, a lower tie rod 2, a large pull ring 3, a turnbuckle 4, a small pull ring 5 and a buckle part 6. One end of the upper tie rod 1 and one end of the lower tie rod 2 are respectively provided with a section of thread a, and the large pull rings 3 are respectively arranged at the non-threaded ends of the upper tie rod 1 and the lower tie rod 2; As Figure 6As shown, the threads a of the upper tie rod 1 and the lower tie rod 2 are respectively threadedly connected to both ends of the turnbuckle 4. The small pull ring 5 is fixedly connected to one end of the buckle member 6. The small pull ring 5 passes through the large pull ring 3, and the buckle member 6 is fixedly connected to the threaded section of the photovoltaic support screw 7 through a fastening bolt. At the same time, the small pull ring 5 has a notch (not shown in the figure), and the width of the notch matches the width of the end plate of the buckle member 6. As Figure 2 shown, preferably, the buckle member 6 includes a first buckle piece 61 and a second buckle piece 62 that are symmetrically arranged. After the first buckle piece 61 and the second buckle piece 62 are buckled, a cavity for surrounding the photovoltaic support screw 7 is formed. Fastening holes b are respectively provided on the end ear plates of the first buckle piece 61 and the second buckle piece 62. The inner diameter dimension of the fastening holes b matches that of the fastening bolt. By passing the fastening bolt through the fastening holes b on the end ear plates of the first buckle piece 61 and the second buckle piece 62 respectively, the buckle member 6 is hoop-mounted on the threaded section of the photovoltaic support screw 7, and the diameter of the adopted fastening bolt needs to match the diameter of the fastening hole b. Preferably, the small pull ring 5 is fixedly welded to one end of the buckle member 6, and the large pull ring 3 is fixedly welded to the non-threaded ends of the upper tie rod 1 and the lower tie rod 2.

[0026] In the present utility model, two small pull rings are provided at one end of each buckle member. One small pull ring 5 is respectively fixed at the same end of the first buckle piece 61 and the second buckle piece 62, so that the two small pull rings are arranged in parallel, and the two small pull rings 5 respectively pass through the same large pull ring 3 to form a loop, making the entire inclined pull support more stable.

[0027] In order to fix the buckle member more firmly on the photovoltaic support screw 7, as Figure 2 shown, thread segments c are provided on the inner side surfaces of the first buckle piece 61 and the second buckle piece 62. When the first buckle piece 61 and the second buckle piece 62 are buckled, the thread segments formed inside the buckle member correspond to the threaded section on the photovoltaic support screw 7, thereby further enhancing the connection between the buckle member 6 and the photovoltaic support screw 7, as Figure 4 and Figure 5 shown.

[0028] In the present utility model, the first buckle piece 61 and the second buckle piece 62 in one buckle member 6 are sleeved on the exposed threaded section on the upper side of one photovoltaic support screw, while the other buckle member is sleeved on the exposed threaded section on the lower side of the adjacent photovoltaic support screw. At the ear plate positions of each buckle piece, after passing a bolt through the corresponding fastening hole b, the first buckle piece and the second buckle piece are fastened. The fastening bolt needs to match the size of the fastening hole on the buckle piece ear plate; after the buckle member is installed on the photovoltaic support screw, the upper tie rod and the lower tie rod are tensioned with the turnbuckle 4.

[0029] By connecting (pre-fabricating) the large pull ring, buckle piece, small pull ring and pull rod, and then using two bolts to fix one end of the buckle on the upper side of the screw of the photovoltaic support, and similarly fixing the other end of the buckle on the lower side of the screw of the adjacent photovoltaic support. By adjusting the lengths of the upper pull rod and the lower pull rod, it can be applicable to various screw spans. Then, use the turnbuckle in the middle to tighten the two side pull rods to achieve the effect of lateral pull rod support, which greatly improves the overall stability and safety of the photovoltaic support. At the same time, the utility model can convert the horizontal load of the overall photovoltaic array under the action of external force into the tensile force of the pull rod support, greatly limiting the horizontal displacement of the array and improving the safety and stability of the photovoltaic array.
