[0013] The following is in conjunction with the appendix Figure 1-3 The technical solution of this utility model will be further illustrated through specific implementation methods.

[0014] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0015] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can also refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0016] A support structure for photovoltaic brackets includes a column 1 and a main beam 2, the middle part of which is mounted on the top of the column 1. Both the column 1 and the main beam 2 are channel steel, and the structure also includes a support rod 3. The support rod 3 is a hollow round tube; the two ends of the support rod 3 are respectively provided with a storage groove 31, and the storage groove 31 is provided with a first through hole 311; The storage groove 31 extends along the length direction of the support rod 3, and the storage groove 31 is recessed into the outer peripheral surface of the support rod 3 in a direction perpendicular to the length direction of the support rod 3; the first through hole 311 is close to the end of the support rod 3; The two storage slots 31 located at both ends of the support rod 3 are integrally formed by pressing. One end of the support rod 3 is fixed to one end of the main beam 2 through the first fastener passing through the first through hole 311; the other end of the support rod 3 extends obliquely downward and is fixed to the middle of the column 1 through the corresponding first through hole 311 by the second fastener.

[0017] like Figure 1-3 As shown, compared with the channel steel structure support rod in the prior art, the support structure of this utility model is simple and does not require the use of connecting plates. The support rod 3, which is a hollow round tube, has a closed cross-section, which can improve the wind resistance and installation stability of the photovoltaic bracket support structure. The two storage grooves 31 at both ends of the support rod 3 are integrally formed by pressing, without the need for riveting or welding, and have better firmness and processing convenience.

[0018] Preferably, the two side walls of the storage groove 31 are vertical along the length direction perpendicular to the support rod 3; The distance between the two side walls of the storage groove 31 is adapted to the size of the first fastener or the second fastener, and is used to abut against the outer peripheral surface of the first fastener or the outer peripheral surface of the second fastener.

[0019] The spacing between the two side walls of the storage groove 31 is set so that the width of the storage groove 31 is adapted to the size of the first fastener or the second fastener, so that the two side walls of the storage groove 31 abut against the outer peripheral surface of the first fastener or the second fastener.

[0020] like Figure 3 In the embodiment shown, when fixing the end of the support rod 3, the screw of the fastener is passed through the corresponding through hole, and only the nut of the first fastener or the second fastener needs to be tightened with a tool, which can improve the ease of operation of fixing the support rod 3.

[0021] Preferably, the wall of the storage groove 31 is a hollow pipe cavity 313, which extends along the length of the support rod 3; The bottom of the storage trough 31 is formed by two layers of pipe walls that are closely attached to each other.

[0022] like Figure 2 and Figure 3 As shown, the bottom of the receiving trough 31 includes two layers of pipe walls; the wall of the receiving trough 31 is a hollow pipe cavity 313, which extends along the length of the support rod 3. The pipe cavity 313 can act as a reinforcing rib, which can improve the bending strength of the end of the support rod 3 and improve the wind resistance of the support structure.

[0023] Preferably, the outer peripheral surface of the support rod 3 that abuts against the main beam 2 or the column 1 is the contact surface 312, and the contact surface 312 is located at the bottom of the storage groove 31; The contact surface 312 is a plane, and the contact surface 312 extends along the length direction of the support rod 3.

[0024] like Figure 2 and Figure 3 As shown, the contact surface 312 is a flat surface, which can improve the installation stability of the support rod 3 and the main beam 2 or column 1.

[0025] Preferably, the two storage slots 31 are recessed into the two ends of the support rod 3 in opposite directions; Furthermore, the two corresponding contact surfaces 312 are located in the same extended plane.

[0026] like Figure 1-3 As shown, the support rod 3 can abut against the main beam 2 and the column 1 respectively through two contact surfaces 312 located in the same extended plane, so that the connection surface of the main beam 2 and the connection surface of the column 1 abutting against the same support rod 3 are two close vertical surfaces. This can avoid the torsion caused by the misalignment of the connection surfaces of the support structure of the support rod 3, the main beam 2 and the column 1, and prevent the support rod, the main beam 2 or the column 1 from deforming during use.

[0027] Furthermore, multiple second through holes 21 arranged at intervals are respectively provided at both ends of the main beam 2; The column 1 has a plurality of third through holes 11 arranged at intervals in the middle. One end of the support rod 3 is fixed to one end of the main beam 2 after passing through the first through hole 311 and a second through hole 21 in sequence by a first fastener. The other end of the support rod 3 is fixed to the middle of the column 1 by passing through the corresponding first through hole 311 and a third through hole 11 with a second fastener.

[0028] like Figure 1 and Figure 3 As shown, the angle between the main beam 2 and the column 1 can be adjusted by the position of the second through hole 21 through which the first fastener passes, or the position of the third through hole 11 through which the second fastener passes, thereby adjusting the tilt angle of the main beam 2.

[0029] In summary, such as Figure 1-3 The embodiment of the present invention shown has a simple structure for supporting photovoltaic brackets. It does not require connecting plates, which can improve the efficiency of installation work. The cross-section of the hollow round tube support rod 3 is a closed structure, which can improve the installation stability of the photovoltaic bracket support structure. The two storage grooves 31 at both ends of the support rod 3 are integrally formed by pressing, which does not require riveting or welding, and has better firmness and processing convenience.

[0030] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
