[0002] Photovoltaic support structures are mainly used to support and install photovoltaic modules and are a key structure in photovoltaic power generation systems. Photovoltaic support structures are mainly divided into three types: fixed support structures, tracking support structures, and flexible support structures.

They have high power generation capacity and strong power generation stability, and are suitable for plains, relatively flat mountainous areas, and other terrains.

[0003] However, the existing tracking support structure has poor stability and cannot resist uneven settlement in complex sites such as backfilled tailings and backfill soil.

[0004] Therefore, there is an urgent need to propose a photovoltaic tracking bracket structure to solve the above problems. Utility Model Content

[0037] This embodiment provides a photovoltaic tracking bracket structure, which has strong anti-overturning and anti-slip capabilities, strong versatility, and convenient and efficient construction.

[0038] Specifically, such as Figures 1 to 7 As shown, the photovoltaic tracking support structure includes a combined foundation 100, multiple columns 200, multiple truss beams 300, and multiple purlins 400. The combined foundation 100 includes a base plate 110, which is formed of continuous reinforced concrete. The columns 200 are vertically mounted on the base plate 110, and the multiple columns 200 are spaced apart along the length of the base plate 110. The truss beams 300 correspond one-to-one with the columns 200, and the truss beams 300 are rotatably mounted on top of the columns 200. The truss beams 300 can rotate and adjust their angle in a plane perpendicular to the length of the base plate 110. The purlin 400 is located on the side of the truss inclined beam 300 away from the column 200, extends along the length of the base plate 110 and is connected to each truss inclined beam 300 in sequence. Multiple purlins 400 are spaced apart along the length of the truss inclined beam 300, and the photovoltaic panel 10 can be laid on the purlin 400.

[0039] Based on the above design, the base plate 110 is formed by continuous reinforced concrete and is an integral structure with large rigidity and planar dimensions. This allows it to effectively resist the impact of uneven settlement on the photovoltaic tracking support structure, i.e., it has strong anti-overturning and anti-slip capabilities. In addition, the concrete combined foundation 100 has a large self-weight, which can effectively resist wind loads and snow loads transmitted from the superstructure, and has strong versatility. The column 200 is vertically mounted on the base plate 110, and the truss inclined beam 300 is rotatably mounted on top of the column 200. The truss inclined beam 300 can be rotated to adjust its angle. The column 200 is used to elevate the truss inclined beam 300 so that the photovoltaic panel 10 can fully receive solar radiation. The truss inclined beam 300 has high structural strength, supports the photovoltaic panel 10, and has good stability. The column 200 and the truss inclined beam 300 work together to provide good stability. The truss inclined beam 300 is rotatably connected and can adjust the orientation of the photovoltaic tracking bracket structure by monitoring the sun's position, thereby adjusting the orientation of the photovoltaic panel 10, so as to maximize the utilization of solar radiation under the same conditions and increase power generation. The purlins 400 extend along the length of the base plate 110 and are connected to each truss inclined beam 300 in sequence. Multiple purlins 400 are spaced apart along the length of the truss inclined beam 300. The photovoltaic panel 10 can be laid on the purlins 400. The purlins 400 provide strong support stability for the photovoltaic panel 10, and the purlins 400 have strong span applicability, making construction convenient and efficient.

[0040] In this embodiment, multiple columns 200 are evenly distributed on both sides of the base plate 110 in the width direction, and correspondingly, multiple inclined beam supports are also located on both sides of the base plate 110 in the width direction, that is, two rows of photovoltaic panels 10 are set.

[0041] Of course, in other implementations, multiple rows of columns 200 can be spaced along the width of the base plate 110, and correspondingly multiple rows of truss beams 300 can be installed, thereby creating multiple rows of photovoltaic panels 10.

[0042] Optionally, continue as follows Figure 7 As shown, the base plate 110 is provided with pre-embedded bolts 740, and the column 200 is fixed to the base plate 110 by the pre-embedded bolts 740. This ensures that the construction of the combined foundation 100 is not affected during the production and transportation cycles of the column 200 and the truss inclined beam 300. In remote areas and overseas projects, this can effectively ensure that the construction period is not limited by materials.

[0043] Furthermore, each column 200 is fixed to the base plate 110 by multiple pre-embedded bolts 740.

[0044] In this embodiment, a plurality of support columns 120 are provided on the base plate 110, and each support column 120 corresponds to a column 200. Pre-embedded bolts 740 are located on the top of the support column 120. That is, each support column 120 is provided with a plurality of pre-embedded bolts 740, and the support column 120 and the column 200 are connected by a plurality of corresponding pre-embedded bolts 740.

[0045] It should be noted that the support column 120 and the base plate 110 are integrally formed of reinforced concrete.

[0046] Optionally, continue as follows Figures 1 to 3 As shown, the photovoltaic tracking bracket structure also includes a first pressure block 810 and a second pressure block 820. The first pressure block 810 connects the purlin 400 and the edge of the photovoltaic panel 10, and the second pressure block 820 connects the purlin 400 and the middle of the photovoltaic panel 10. The first pressure block 810 fixes the four sides of the photovoltaic panel 10, and the second pressure block 820 fixes other parts of the photovoltaic panel 10, thereby improving the stability of the photovoltaic panel 10.

[0047] Optionally, continue as follows Figure 6 As shown, the photovoltaic tracking bracket structure also includes fastening bolts 410, and the purlins 400 are fixed to the truss inclined beams 300 by the fastening bolts 410.

[0048] Optionally, continue as follows Figure 5 As shown, the photovoltaic tracking bracket structure also includes a first hinge bolt 710. The truss inclined beam 300 and the column 200 are connected by the first hinge bolt 710, realizing the rotational connection of the truss inclined beam 300. The connection is simple and the structure has high strength.

[0049] Optionally, the photovoltaic tracking bracket structure also includes an electric push rod 500, which is fixed to the side wall of the column 200 and its output end is connected to the truss inclined beam 300. The tilt angle of the photovoltaic panel 10 can be adjusted by controlling the length of the electric push rod 500, which is convenient to adjust. The electric push rod 500 is set between the column 200 and the truss inclined beam 300 to form the support system of the photovoltaic tracking bracket structure, thereby improving the stability of the photovoltaic tracking bracket structure.

[0050] Furthermore, the photovoltaic tracking bracket structure also includes two second hinge bolts 720. One second hinge bolt 720 connects the fixed end of the electric push rod 500 and the column 200, and the other second hinge bolt 720 connects the output end of the electric push rod 500 and the truss inclined beam 300. The electric push rod 500 is set between the column 200 and the truss inclined beam 300 by the second hinge bolts 720, which makes the installation simple and the rotation adjustment effect good.

[0051] Optionally, the photovoltaic tracking bracket structure also includes a shock absorber 600, with the two ends of the shock absorber 600 connected to the truss inclined beam 300 and the column 200, respectively. The shock absorber 600 is used to prevent wind vibration caused by extreme wind weather from damaging the photovoltaic tracking bracket structure and the photovoltaic panel 10.

[0052] Furthermore, the shock absorber 600 is a bidirectional damping shock absorber 600, which provides bidirectional damping and has a good damping effect.

[0053] In this embodiment, the photovoltaic tracking bracket structure also includes two third hinge bolts 730, one of which connects the bottom end of the column 200 and the bidirectional damping shock absorber 600, and the other third hinge bolt 730 connects the top end of the truss inclined beam 300 and the bidirectional damping shock absorber 600.
