[0028] The present invention is described in detail below in conjunction with the accompanying drawings and embodiments.

[0029] like Figure 1-Figure 2As shown, a foldable photovoltaic support structure includes a support column 1, a support frame and a support frame. The support column 1 is used to support the overall structure, and the support frame is connected to the top of the support column, used to carry the photovoltaic panel, and is hinged to the support column. The support frame is connected between the support column and the support frame, and the support frame is a length-adjustable structure, the support frame is hinged to the support column, and is hinged to the support frame, so that the folding of the bracket during installation is achieved through the length-adjustable structure and the hinged structure.

[0030] It should be noted that in order to clearly reflect the structural relationship, the connection positions of each structure in the drawings of the specification are drawn with connection holes, but no connecting bolts are drawn. In actual use, they can be fixedly connected by bolts according to actual needs, or rotated by structures such as connecting shafts.

[0031] like Figure 3 As shown, the support column 1 includes a first support column 11 located at the bottom and a second support column 12 located above the first support column. Flanges are designed at both ends of the first support column 11. The bottom flange is used to connect to the base and be fixed on the ground, and the top flange is used to connect to the second support column. A flange is correspondingly provided at the bottom of the second support column, which is fixedly connected to the first support column with connecting bolts (not shown in the figure); a connecting block is connected to the top of the second support column, which can be used to form a hinge with structures such as connecting holes and connecting shafts to achieve hinged connection with other structures. The first support column 11 is a cylindrical structure, and the second support column is a truncated cone structure, with the upper diameter being smaller than the lower diameter. A number of reinforcing ribs are also provided between the flange and the support column to reinforce the structure.

[0032] like Figure 1 As shown, the carrier frame includes a central support rod 21 connected to the support column 1, a transverse support rod 22 hinged on the central support rod 21, and a longitudinal support rod 23 connected to the upper part of the transverse support rod 22. The transverse support rod 22 is perpendicular to the longitudinal support rod 23, and the central support rod 21 is parallel to the longitudinal support rod 23, thereby forming a frame structure for supporting the photovoltaic panel, and the photovoltaic panel is fixedly installed on the longitudinal support rod 23 during installation.

[0033] The structure should be designed as symmetrically as possible to ensure force balance. Therefore, the transverse support rods are preferably symmetrically arranged on both sides of the central support rod, and the longitudinal support rods are also preferably symmetrically arranged on both sides of the central support rod, that is, balance is maintained in both the transverse and longitudinal directions.

[0034] Each longitudinal support rod is connected to the transverse support rod through an L-shaped connecting plate. Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6As shown, screw holes are provided on both sides of the L-shaped connecting plate 4, and screw holes are designed corresponding to the positions where the longitudinal support rods and the transverse support rods are connected to the L-shaped connecting plate. The longitudinal support rods, the L-shaped connecting plate and the transverse support rods are fixedly connected by bolts.

[0035] Each group of photovoltaic panels is fixed by two adjacent longitudinal support rods, so the number of longitudinal support rods is an even number, and two adjacent longitudinal support rods form a longitudinal support rod group. The longitudinal support rods in the same longitudinal support rod group are connected to the transverse support rods using L-shaped connecting plates of the same length. In order to enhance the wind resistance, there is a certain height difference between adjacent photovoltaic panels after adjacent installation to form a wind vent, so the longitudinal support rods of adjacent longitudinal support rod groups are connected to the transverse support rods using L-shaped connecting plates of different lengths. Figure 5 The L-shaped connecting plate with a longer length is shown, and another set of longitudinal support rods adjacent to it is used as shown in the figure. Figure 6 L-shaped connecting plate shown in shorter length.

[0036] The support frame includes a first connecting rod 31, a second connecting rod 32, a third connecting rod 33, a first adjusting rod 34 and a second adjusting rod 35. The first end of the first connecting rod 31 is rigidly connected to the lower part of the second supporting column 12, the second end of the first connecting rod 31 is hinged to the first end of the second connecting rod 32, the second end of the second connecting rod 32 is hinged to the first end of the third connecting rod 33 and the first end of the first adjusting rod 34, and the second end of the third connecting rod 33 is hinged to the end of the central support rod 21. The second end of the first adjusting rod 34 is sleeved with the first end of the second adjusting rod 35, and the second end of the second adjusting rod 35 is hinged to the transverse support rod 22. The first connecting rod 31 is parallel to the central support rod 21.

[0037] The support frame also includes a third adjustment rod 36 and a fourth adjustment rod 37. The first end of the third adjustment rod 36 is hinged to the second end of the first connecting rod 31, the second end of the third adjustment rod 36 is sleeved to the first end of the fourth adjustment rod 37, and the second end of the fourth adjustment rod 37 is hinged to the end of the central support rod 21.

[0038] The first adjustment rod 34 and the second adjustment rod 35 are sleeved together, and the sleeve joint is fixed by multiple rows of mounting holes with bolts. The first adjustment rod 34 and the second adjustment rod 35 are used to achieve horizontal folding. When the photovoltaic panel needs to be installed, the bolts connected to the multiple rows of mounting holes are removed, and the second adjustment rod 35 can be inserted into the first adjustment rod 34. At this time, the horizontal support rod 22 can rotate with the central support rod 21 as the axis until the end falls to the ground. At this time, the photovoltaic panel can be installed on the ground. The structure of the multiple rows of mounting holes 5 is as follows: Figure 7 As shown, the first end of the second adjusting rod 35 can be used to adjust the position angle of the lateral support rod after it is raised as needed.

[0039] The third adjustment rod 36 and the fourth adjustment rod 37 are used to achieve longitudinal angle adjustment, so as to achieve the on-demand adjustment of the angle of the photovoltaic panel. The orientation of the photovoltaic tree after the photovoltaic panel is installed is preferably designed so that the lateral support rod indicates the east-west direction, and the longitudinal support rod and the central support rod indicate the north-south direction, so as to facilitate the east-west lateral folding and the north-south longitudinal angle adjustment. The diameter of the fourth adjustment rod 37 is smaller than that of the third adjustment rod 36, and the connection between the two also adopts multiple rows of mounting holes. The multiple rows of mounting holes are arranged at the first end of the fourth adjustment rod 37, and the corresponding second end of the third adjustment rod 36 is provided with a connecting hole. By connecting to the hole positions of different multiple rows of mounting holes, the extension length of the fourth adjustment rod 37 can be adjusted on demand, thereby adjusting the overall length of the third adjustment rod 36 and the fourth adjustment rod 37, and then cooperating with the rotation of the hinged structure of each part to achieve the angle adjustment of the photovoltaic panel.

[0040] A connecting rod may be added between the first adjusting rod 34 and the transverse support rod 22. A supporting rod parallel to the central supporting rod 21 may be added at the connection between the second adjusting rod 35 and the transverse support rod 22, and connected between the transverse support rods to achieve structural reinforcement. The lower part of the transverse support rod 22 located on the inner side may not be connected to the adjusting rod, and a connecting rod without telescopic function may be used in conjunction with a cable connected to the support column, which can also meet the strength requirements, further reduce the construction difficulty, and improve the installation efficiency.

[0041] In some embodiments, a photovoltaic tree is further provided, such as Figure 8 As shown, a foldable photovoltaic support structure provided above is used as a branch, and a photovoltaic panel 6 is fixedly installed on the upper part of the top support frame to obtain a photovoltaic tree with horizontal foldability, longitudinal adjustment, good wind resistance and low construction difficulty.

[0042] The utility model designs the transverse structure to be foldable. When installing the photovoltaic panel, the support frame with adjustable length can be retracted and the hinge relationship between the structures can be coordinated to achieve transverse folding, so that the photovoltaic panel can be installed without hoisting. The installation difficulty is low and it is not restricted by the terrain, which expands the scope of application of the photovoltaic tree. The overall support structure adopts the design idea of ​​the tree growing upward. The north-south longitudinal light angle is adjustable. Through the sleeve telescopic structure of the third adjustment rod and the fourth adjustment rod and the hinge relationship between the parts, it can be adjusted with the change of seasons and regions; it can be folded horizontally from east to west. When installing the photovoltaic panel, the adjustment rod is retracted to reduce the installation height. After the installation is completed, the adjustment rod is propped up. At the same time, the horizontal direction can be adjusted arbitrarily according to actual needs. The lengths of the L-shaped connecting plates between adjacent longitudinal support rod groups are different, so that after the photovoltaic panel is installed, a vent can be formed between adjacent photovoltaic panels, which can effectively reduce the windward area and enhance the wind resistance. The overall support structure is compact and shared by multiple nodes, which can save the number of sheet metal parts, greatly reduce costs, and save installation time.

[0043] Although the above describes the specific implementation methods of the utility model in combination with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
