Furthermore, the drawings are merely illustrative of this disclosure and are not necessarily drawn to scale.

[0039] Unless otherwise specified or stated, the technical or scientific terms used in this disclosure shall have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains. The terms “a,” “an,” “the,” “the,” and “at least one” are used to indicate the presence of one or more elements / components / etc.; the terms “comprising” and “having” are used to indicate an open-ended inclusion and to mean that there may be other elements / components / etc. in addition to those listed; the terms “first” and “second” are used only as illustrative marks and are not intended to limit the number, importance, or order of the objects.

[0040] The terms “connection” and “fixation” should be interpreted broadly. For example, unless otherwise specified, “connection” can be a fixed connection, a movable connection, an integral connection, or a detachable connection. It can be a direct connection or an indirect connection through an intermediate medium.

[0041] Furthermore, in this application, directional terms such as "upper" and "lower" are used only to indicate relative positional relationships. For example, for convenience, they are defined based on the actual position and state of the photovoltaic support during operation, or relative to the indicated placement of components in the accompanying drawings. For example, photovoltaic module 5 is located "upper," and pile foundation 1 is located "lower." It should be understood that these directional terms are relative concepts and can change accordingly depending on the orientation of the components in the accompanying drawings.

[0042] This disclosure provides a photovoltaic fixing bracket supported by a truss structure, with reference to... Figure 1 As shown, it includes a support unit and a crossbeam 4.

[0043] The support unit includes a pile foundation 1, a column 2, and a support structure. The column 2 is located on top of the pile foundation 1. The support structure includes a first inclined beam 31, a second inclined beam 32, a third inclined beam 33, and connecting rods. One end of the first inclined beam 31 and one end of the second inclined beam 32 are respectively connected to the column 2. Both ends of the third inclined beam 33 are respectively connected to the other ends of the first inclined beam 31 and the second inclined beam 32. At least one connecting rod connects the first inclined beam 31 and the third inclined beam 33, and at least one connecting rod connects the second inclined beam 32 and the third inclined beam 33.

[0044] The support units are arranged in pairs, with multiple crossbeams 4 spanning between two third diagonal beams 33 for installing photovoltaic modules 5.

[0045] The connection points of the first inclined beam 31 and the third inclined beam 33, the connection points of the second inclined beam 32 and the third inclined beam 33, the connection points of the connecting rod on the first inclined beam 31 and the third inclined beam 33, and the connection points of the connecting rod on the second inclined beam 32 and the third inclined beam 33 are adjustable in multiple positions.

[0046] refer to Figure 1 As shown, the photovoltaic fixing bracket supported by the truss structure provided in this disclosure is configured as a truss structure. The first inclined beam 31, the second inclined beam 32, and the third inclined beam 33 form an inverted triangular support structure, with an adjustable connecting rod system embedded inside. Utilizing the geometric relationship of the triangle, it has better resistance to severe weather such as strong winds, thereby greatly reducing loss costs. Moreover, the adjustable design of the connection points between the first inclined beam 31, the second inclined beam 32, and the third inclined beam 33, as well as the connection points of the connecting rods on the first inclined beam 31 and the third inclined beam 33, and on the second inclined beam 32 and the third inclined beam 33, makes transportation and installation more convenient, saves construction costs, reduces construction risks, and improves the problem of difficult angle adjustment when supporting photovoltaic panels in related technologies. This makes it easier to meet design requirements and construction needs, and improves construction accuracy.

[0047] It should be noted that in the "photovoltaic fixed bracket supported by a truss structure" described in this disclosure, "fixed" refers to a bracket that rotates with the sun, a flexible bracket that uses steel cables to install the photovoltaic modules 5, and whose structural form changes with the load. The aforementioned description of "adjustable" indicates that the tilt angle of the photovoltaic modules 5 on the bracket can be manually adjusted before or after installation, and can be fixed again after adjustment.

[0048] Below, in conjunction with the appendix Figures 1 to 3 The specific structure of the photovoltaic fixed bracket supported by the truss structure provided in this disclosure will be further explained. Among other things, Figure 1 A schematic diagram of a photovoltaic mounting bracket supported by a truss structure is shown in an exemplary embodiment. Figure 2 It shows Figure 1 A magnified view of a portion of region A in the middle. Figure 3 It shows Figure 1 A magnified view of a portion of region B in the middle.

[0049] refer to Figure 1 As shown, the pile foundation 1 can be a precast pipe pile foundation 1 with a steel plate connected by an embedded part at the top, or a reinforced concrete cast-in-place pile foundation 1 with a steel plate or anchor bolt connected by an embedded part. Other foundation types can also be used as needed, as long as they meet the requirements for exposed ground height, foundation stress and connection.

[0050] Column 2 is installed on top of pile foundation 1. For example, column 2 can be a circular steel pipe, installed vertically. The bottom of column 2 is welded to a pre-embedded steel plate on the top surface of pile foundation 1. Alternatively, the shape, material, and other connection types can be customized as needed.

[0051] For example, a clamp 7 is fitted onto the column 2, and one end of the first inclined beam 31 is welded to the clamp 7; one end of the second inclined beam 32 is welded to the clamp 7. (Reference) Figure 1As shown, the clamp 7 can be composed of two semi-circular devices, each with a pair of bolt holes on both sides, and is fixed to the column 2 by bolt connection. In an exemplary embodiment, the connection point of the first inclined beam 31 on the clamp 7 is lower than the connection point of the second inclined beam 32 on the clamp 7.

[0052] The supporting structure includes a first inclined beam 31, a second inclined beam 32, a third inclined beam 33, and connecting rods. The lengths of the first inclined beam 31, second inclined beam 32, and third inclined beam 33 can be different, and the material can be Q235 steel. The first inclined beam 31 and second inclined beam 32 can be non-standard steel sections. Each of the first and second inclined beams 31 and 32 can have a lug at one end. The lugless ends of the first and second inclined beams 31 and 32 are welded to the clamp 7, and the lug-equipped ends are connected to both ends of the third inclined beam 33.

[0053] Multiple crossbeams 4 span between two third diagonal beams 33 for mounting photovoltaic modules 5. For example, the multiple crossbeams 4 are of equal length, the two third diagonal beams 33 are parallel to each other, and a photovoltaic mounting bracket unit supported by a truss structure can have four crossbeams 4 at the top, with each crossbeam 4 spaced at a certain distance. The photovoltaic modules 5 are laid in two layers on the crossbeams 4.

[0054] In particular, it should be noted that the reference Figure 1 As shown, the two ends of the third inclined beam 33 described in this disclosure can refer to the two heads near the third inclined beam 33, and do not strictly refer to the heads of the third inclined beam 33. For example, the two ends of the third inclined beam 33 are respectively provided with connecting parts, see reference. Figure 1 As shown, the connecting part can be a certain distance from the head of the third inclined beam 33. In this disclosure, the first inclined beam 31 and the second inclined beam 32 are connected to both ends of the third inclined beam 33, and at least one connecting rod is connected between the first inclined beam 31 and the third inclined beam 33; at least one connecting rod is connected between the second inclined beam 32 and the third inclined beam 33, which means that the connection points of the connecting rods on the third inclined beam 33 are all located between the connecting parts at both ends of the third inclined beam 33.

[0055] For example, the connection includes at least two sets of bolt holes arranged side-by-side along the length of the beam. (Reference) Figures 1 to 3 As shown, one end of the first inclined beam 31 is connected to a set of bolt holes in the connecting portion at one end of the third inclined beam 33; one end of the second inclined beam 32 is connected to a set of bolt holes in the connecting portion at the other end of the third inclined beam 33. For example, the connecting portion may include three sets of bolt holes arranged side by side along the length of the beam. When the first inclined beam 31 and the second inclined beam 32 are connected to the connecting portion, their positions can be finely adjusted by connecting to different bolt holes within the connecting portion. Through the multiple pairs of bolt holes in the connecting portion, the position of the adjustable connector can be flexibly adjusted, thereby effectively improving the problem of the angle being difficult to adjust when the photovoltaic mounting bracket supports the photovoltaic panel.

[0056] In one exemplary embodiment of this disclosure, at least two sets of connecting portions are provided between the two ends of the third inclined beam 33; each connecting portion is connected to one end of two connecting rods. For example, refer to... Figure 1 As shown, the two connecting parts at both ends of the third inclined beam 33 are connected to the first inclined beam 31 and the second inclined beam 32, respectively. Two sets of connecting parts can also be provided between the two connecting parts at both ends, and each connecting part can be connected to one end of two connecting rods. The other ends of the two connecting rods connected to the same connecting part are separate and can be supported on the first inclined beam 31 and the second inclined beam 32, or at different positions on the second inclined beam 32, to improve the overall stability of the support structure.

[0057] For example, refer to Figure 1 As shown, a connecting portion is provided between the two ends of the first inclined beam 31; one end of at least one connecting rod is connected to a set of bolt holes in the connecting portion of the first inclined beam 31; a connecting portion is provided between the two ends of the second inclined beam 32; one end of at least one connecting rod is connected to a set of bolt holes in the connecting portion of the second inclined beam 32.

[0058] In one exemplary embodiment of this disclosure, the third inclined beam 33 is provided with a first connecting portion, a second connecting portion, a third connecting portion and a fourth connecting portion in sequence; a fifth connecting portion is provided between the two ends of the first inclined beam 31; and a sixth connecting portion and a seventh connecting portion are provided between the two ends of the second inclined beam 32.

[0059] The connecting rods include a first connecting rod 341, a second connecting rod 342, a third connecting rod 343, and a fourth connecting rod 344.

[0060] refer to Figure 1 As shown, one end of the first inclined beam 31 is connected to a set of bolt holes in the first connecting part. One end of the first connecting rod 341 is connected to a set of bolt holes in the fifth connecting part, and the other end is connected to a set of bolt holes in the second connecting part. One end of the second connecting rod 342 is connected to a set of bolt holes in the sixth connecting part, and the other end is connected to a set of bolt holes in the second connecting part. One end of the third connecting rod 343 is connected to a set of bolt holes in the sixth connecting part, and the other end is connected to a set of bolt holes in the third connecting part. One end of the fourth connecting rod 344 is connected to a set of bolt holes in the seventh connecting part, and the other end is connected to a set of bolt holes in the third connecting part. One end of the second inclined beam 32 is connected to a set of bolt holes in the fourth connecting part.

[0061] In one exemplary embodiment of this disclosure, the first connecting rod 341 and the second connecting rod 342 are connected to the same set of bolt holes in the second connecting portion. The third connecting rod 343 and the fourth connecting rod 344 are connected to the same set of bolt holes in the third connecting portion. The second connecting rod 342 and the third connecting rod 343 are connected to the same set of bolt holes in the sixth connecting portion.

[0062] The first connecting rod 341, the second connecting rod 342, the third connecting rod 343, and the fourth connecting rod 344 can be short rods of different lengths, each with an ear plate at both ends. They are all made of Q235. The four short rods are installed between the three inclined beams through the fifth connecting part, the second connecting part, the sixth connecting part, the third connecting part, and the seventh connecting part in sequence. The whole structure is "M" shaped and embedded in the inverted triangular support structure.

[0063] Specifically, the first connecting rod 341 and the second connecting rod 342 are connected to the second connecting part via a first connecting member. (Reference) Figure 1 as well as Figure 3 As shown, the first connector includes a first connecting plate 61, a second connecting plate, a first connecting lug 62 disposed at the end of the first connecting plate 61, and a second connecting lug disposed at the end of the second connecting plate.

[0064] refer to Figure 3 As shown, the first connecting plate 61 and the second connecting plate are respectively attached to opposite sides of the same set of bolt holes in the second connecting part. The distance between the first connecting ear plate 62 and the second connecting ear plate is less than the distance between the first connecting plate 61 and the second connecting plate. The first connecting rod 341 is connected to the first connecting ear plate 62, and the second connecting rod 342 is connected to the second connecting ear plate. The first connecting member can be used to install the first connecting rod 341 and the second connecting rod 342 to the second connecting part on the third inclined beam 33. During installation, the first connecting member can be fixed to the third inclined beam 33 by bolts passing through the corresponding bolt holes of the first connecting plate 61, the second connecting plate, and the second connecting part. The first connecting rod 341 and the second connecting rod 342 can be installed to the first connecting member by bolts passing through the structure at the ends of the first connecting ear plate 62, the second connecting ear plate, and the first connecting rod 341 and the second connecting rod 342, such as through the ear plate at the end of the connecting rod. The first connecting member can accommodate the thickness of the third inclined beam 33.

[0065] In some embodiments, a first mounting plate may be provided between the first connecting plate 61 and the second connecting plate. The first mounting plate is sandwiched between the first connecting plate 61 and the second connecting plate and is arranged along the thickness direction of the third inclined beam 33, so that the first connecting plate 61, the second connecting plate and the first mounting plate form a "U" shape, which can be directly snapped onto the third inclined beam 33 and fixed by threaded connectors.

[0066] In one exemplary embodiment of this disclosure, the fifth connecting portion may be located at 1 / 3 of the length of the first inclined beam 31 from the end where the first inclined beam 31 connects to the column 2. The sixth connecting portion may be located at 1 / 3 of the length of the second inclined beam 32 from the end where the second inclined beam 32 connects to the column 2. The seventh connecting portion may be located at 1 / 3 of the length of the second inclined beam 32 from the end where the second inclined beam 32 connects to the third inclined beam 33. The first inclined beam 31, the second inclined beam 32, the third inclined beam 33, the first connecting rod 341, the second connecting rod 342, the third connecting rod 343, and the fourth connecting rod 344 can form multiple sets of nested triangular structures, which is beneficial to improving resistance to severe weather such as strong winds.

[0067] In one exemplary embodiment of this disclosure, reference is made to Figure 2 As shown, the first connecting rod 341 is connected to the fifth connecting part via a second connecting member. The second connecting member includes a third connecting plate 81, a fourth connecting plate, a third connecting lug 82 located at the end of the third connecting plate 81, and a fourth connecting lug 82 located at the end of the fourth connecting plate. The third connecting lug 82 and the fourth connecting lug 82 are respectively attached to opposite sides of the same set of bolt holes in the fifth connecting part, and the distance between the third connecting lug 82 and the fourth connecting lug 82 is less than the distance between the third connecting plate 81 and the fourth connecting plate. The first connecting rod 341 is connected to the third connecting lug 82 and the fourth connecting lug 82. During installation, the second connecting member can be fixed to the first inclined beam 31 by bolts passing through the corresponding bolt holes of the third connecting plate 81, the fourth connecting plate, and the fifth connecting part. The first connecting rod 341 can be installed to the second connecting member by bolts passing through the structure at the end of the first connecting rod 341, such as through the lug 82 at the end of the connecting rod. The second connecting member can accommodate the thickness of the first inclined beam 31.

[0068] In some embodiments, a second mounting plate may be provided between the third connecting plate 81 and the fourth connecting plate. The second mounting plate is sandwiched between the third connecting plate 81 and the fourth connecting plate and is arranged along the thickness direction of the first inclined beam 31, so that the third connecting plate 81, the second mounting plate and the fourth connecting plate form a "U" shape, which can be directly clamped on the first inclined beam 31 and fixed by threaded connectors.
