For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] In photovoltaic power generation applications, the stability of the purlins of photovoltaic brackets under wind suction is an important factor affecting the safety of photovoltaic brackets. The current conventional solution is to use purlins with higher steel content, which is not conducive to controlling the cost of photovoltaic brackets, and requires drilling holes at the corresponding positions of the purlins, which weakens the purlin structure itself to a certain extent.

[0037] In order to overcome at least one defect of the prior art, the present application proposes a support structure that can improve the stability of the purlin under wind suction without increasing the steel content of the purlin. There is no need to open holes in the purlin, and the structure of the purlin itself is not damaged or weakened.

[0038] Please refer to Figures 1 to 5 The support structure provided in this embodiment is used in a photovoltaic module to support and stabilize the purlin 110, thereby improving the stability of the purlin 110 under wind suction. Of course, the support structure can also be used in other support fields to improve the strength and stability of the support.

[0039] The support structure includes a stabilizing hoop 120 and a fixing block 170. The stabilizing hoop 120 is provided with an installation cavity 121 for accommodating the purlin 110. The installation cavity 121 has an opening 123. The fixing block 170 is connected to the stabilizing hoop 120 and covers the opening 123; the fixing block 170 is used to connect with the purlin 110. Among them, the cross-sectional area of ​​the installation cavity 121 gradually decreases from one end close to the opening 123 to the end away from the opening 123. In the support structure, the stabilizing hoop 120 is formed with the installation cavity 121 for accommodating the purlin 110. The stabilizing hoop 120 and the fixing block 170 work together to effectively support and stabilize the purlin 110, thereby improving the stability of the purlin 110 under the action of wind suction. In addition, the installation cavity 121 adopts a variable cross-sectional area design, and the cross-sectional area of ​​the installation cavity 121 gradually decreases from the end close to the opening 123 to the end far from the opening 123, so that it can adapt to purlins 110 of various shapes and sizes, effectively support and fix the purlins 110, and have flexible application scenarios. In addition, there is no need to open holes on the purlins 110, which is conducive to maintaining the strength of the structure of the purlins 110 itself. The support structure is simple, easy to assemble, and highly versatile, which is conducive to controlling the cost of the photovoltaic bracket 100.

[0040] The stabilizing hoop 120 includes a first segment 130, a second segment 140, and a third segment 150 connected in sequence. The first segment 130 and the third segment 150 are arranged opposite to each other. One end of the second segment 140 is connected to the first segment 130, and the other end is connected to the third segment 150. The first segment 130, the second segment 140, and the third segment 150 together form an installation cavity 121 for accommodating the purlin 110. The stabilizing hoop 120 forms an opening 123 on the side opposite to the second segment 140. During installation, the purlin 110 is inserted into the installation cavity 121 from the opening 123. The first segment 130 and the third segment 150 are respectively connected to the fixing block 170. Along the direction from the second segment 140 to the opening 123, the distance between the first segment 130 and the third segment 150 gradually increases, so that the installation cavity 121 forms a variable cross-section design, so that purlins 110 of various shapes and sizes can be inserted into the installation cavity 121, thereby achieving effective support and fixation of purlins 110 of various shapes and sizes, with strong versatility and flexible application scenarios.

[0041] It should be noted that the stabilizing hoop 120 is generally U-shaped and can be formed by bending a steel bar. The cross section of the steel bar can be any shape such as circular, elliptical, triangular, diamond, square, trapezoidal, rectangular, pentagonal, hexagonal or octagonal.

[0042] Optionally, the fixing block 170 is provided with a first mounting hole 171, and the first segment 130 and the third segment 150 are respectively inserted into the first mounting holes 171 to achieve the connection between the stabilizing hoop 120 and the fixing block 170. It can be understood that the fixing block 170 is provided with two first mounting holes 171, and the two first mounting holes 171 are arranged at opposite ends of the fixing block 170, the first segment 130 is inserted into one of the first mounting holes 171, and the third segment 150 is inserted into the other first mounting hole 171. In this embodiment, the support structure further includes a fastener, and the first segment 130 and the third segment 150 are respectively provided with a locking portion 160 at one end away from the second segment 140, and the first segment 130 and the third segment 150 are respectively inserted into the first mounting holes 171, and the fastener is connected to the locking portion 160, and the fastener is located on the side of the fixing block 170 away from the second segment 140. Optionally, the fasteners include but are not limited to nuts (not shown), the locking portion 160 includes external threads provided on the first segment 130 and the third segment 150, and the nuts are threadedly connected to the first segment 130 and the third segment 150, respectively. Two nuts can be provided on the first segment 130 and the third segment 150, respectively, and the double nut structure is adopted to achieve the purpose of tightening and preventing loosening, and the structure is more reliable, which can ensure the reliable connection between the fixing block 170 and the stabilizing hoop 120 for a long time. The surface of the fixing block 170 in contact with the photovoltaic module should be able to fit tightly with the frame of the photovoltaic module.

[0043] Of course, in some other embodiments, the fixing block 170 and the stabilizing hoop 120 may also be connected by clamping, bonding, riveting, welding, screw connection, pin connection or other connection methods, which are not specifically limited here.

[0044] Optionally, the first segment 130 includes a first vertical portion 131 and a first inclined portion 133 connected to each other, and the first vertical portion 131 is connected to a fixing block 170. The first inclined portion 133 is connected to the second segment 140 at one end away from the first vertical portion 131, and the first inclined portion 133 extends from the end of the first vertical portion 131 into the installation cavity 121. The third segment 150 includes a second vertical portion 151 and a second inclined portion 153 connected to each other, and the second vertical portion 151 is connected to a fixing block 170. The second inclined portion 153 is connected to the second segment 140 at one end away from the second vertical portion 151, and the second inclined portion 153 extends from the end of the second vertical portion 151 into the installation cavity 121. That is, in this embodiment, the installation cavity 121 adopts a variable cross-section design at the position corresponding to the first inclined portion 133 and the second inclined portion 153. Optionally, the distance between the first inclined portion 133 and the second inclined portion 153 gradually increases along the direction from the second segment 140 to the opening 123. The first inclined portion 133 and the second inclined portion 153 are used to abut against the purlin 110 respectively.

[0045] Since the first inclined portion 133 and the second inclined portion 153 are designed to be inclined relative to the vertical plane, purlins 110 of different sizes can be abutted at different positions of the first inclined portion 133 and the second inclined portion 153, so that the stabilizing hoop 120 can effectively fix the purlin 110, and can form a tight connection with the purlins 110 of various cross-sectional shapes and sizes, effectively preventing the horizontal movement of the lower flange of the purlin 110 when it is compressed and unstable, thereby improving the stability of the purlin 110. Figure 5 The three figures (a), (b) and (c) respectively represent schematic diagrams of matching purlins 110 with three different cross-sectional shapes with the supporting structure. Of course, it is not limited to the purlins 110 with these three shapes. The supporting structure provided in this embodiment is applicable to purlins 110 with any other shapes.

[0046] Optionally, the fixing block 170 is provided with a second mounting hole 173, and the second mounting hole 173 is used to fix the purlin 110. Screws or bolts can be inserted into the second mounting hole 173 to fix the fixing block 170 and the purlin 110, thereby further improving the stability and reliability of the structure. Of course, it is not limited to this, and the purlin 110 and the fixing block 170 can also be connected by clamping, bonding, riveting, welding or other connection methods, which are not specifically limited here.

[0047] The embodiment of the utility model further provides a photovoltaic support 100, comprising a purlin 110 and a support structure as described in any one of the aforementioned embodiments, wherein the support structure and the purlin 110 are connected.

[0048] Optionally, the photovoltaic bracket 100 provided in this embodiment has the following installation process:

[0049] The purlin 110 is inserted into the opening 123 of the stabilizing hoop 120, that is, the first segment 130 and the third segment 150 are relatively located on both sides of the purlin 110, and the purlin 110 is located in the installation cavity 121 of the stabilizing hoop 120. The fixing block 170 is straddled on the purlin 110 and connected to the first segment 130 and the third segment 150 of the stabilizing hoop 120, that is, the first segment 130 and the third segment 150 pass through the first installation hole 171 of the fixing block 170, respectively, and the double nuts are tightened, so that the two sides of the lower wing of the purlin 110 are respectively in contact with the first inclined portion 133 and the second inclined portion 153, and the upper surface of the purlin 110 is in contact with the fixing block 170. Further, the purlin 110 and the fixing block 170 are connected by bolts or screws, which limits the freedom of the purlin 110 in six directions and effectively improves the stability of the purlin 110.

[0052] The supporting structure proposed in the embodiment of the utility model, the stabilizing hoop 120 is formed with an installation cavity 121 for accommodating the purlin 110, and the stabilizing hoop 120 and the fixing block 170 work together to effectively support and stabilize the purlin 110, thereby improving the stability of the purlin 110 under the action of wind suction. In addition, the installation cavity 121 adopts a variable cross-sectional area design, and the cross-sectional area of ​​the installation cavity 121 gradually decreases from the end close to the opening 123 to the end away from the opening 123, so that it can adapt to purlins 110 of various shapes, effectively support and fix the purlin 110, and the application scenario is flexible.
