[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0044] Example 1

[0045] See also Figure 1-Figure 7 As shown, a photovoltaic support device of this embodiment includes a base 1, a column 2, a beam 3 and a short beam 4.

[0046] The bottom end of the column 2 is rotatably connected to the base 1 via a first rotating shaft;

[0047] The crossbeam 3 is rotatably connected to the top of the column 2 via a second rotating shaft;

[0048] The short beam 4, the middle end of which is rotatably connected to the cross beam 3 via a third rotating shaft; the short beam 4 can be rotated horizontally and adjusted in angle up and down via the third rotating shaft;

[0049] The base 1 , the uprights 2 , the cross beams 3 and the short beams 4 can be rotated to the same length direction when stored; and can be rotated to a desired position and fastened and limited by the fasteners 6 when installed.

[0050] Preferably, the first rotating shaft is a first bolt, the second rotating shaft is a second bolt, the third rotating shaft is a third bolt, and the fastener is a fourth bolt.

[0051] Due to the provision of the first rotating shaft, the second rotating shaft and the third rotating shaft, the base, the column, the cross beam and the short beam can be rotated to the same length direction when stored; during installation, they can be rotated to the required position and fastened and limited by fasteners, so that when rotated to the same length direction, the transportation volume of the integral structure is greatly reduced. Since the first rotating shaft, the second rotating shaft, the third rotating shaft and the fasteners can be standard parts, no special tools are required for on-site assembly, and the angle adjustment is easy through the third rotating shaft.

[0052] As a specific embodiment, the base 1 is fixed with a clamping plate 5, which is provided with a plurality of first coupling holes for fasteners to pass through the first coupling holes and fasten and limit with the column. Figure 2-Figure 4As shown, preferably, there can be multiple clamping plates, which are arranged around the column, so that they can be fastened and limited to the column in the front, back, left, and right directions by bolts passing through the first connecting holes, thereby achieving four-way limitation. Of course, this is the fastening and limiting after the column, crossbeam and short beam are rotated to the required position during installation. In this way, the base, as the basic structure, is different from the traditional welding process in the basic structure. The base is formed by an integrated processing process, and is positioned with the clamping plates to reduce welding processing. While installing the limit, it can achieve the limitation in the four directions of east, west, south and north, ensuring strength while further reducing material costs.

[0053] As a specific embodiment, the crossbeam is provided with a plurality of second coupling holes for fasteners to pass through the second coupling holes and fasten and limit with the columns. This is also the fastening and limiting after the columns, crossbeams and short beams are rotated to the required positions during installation.

[0054] As a specific embodiment, there are two short beams and two corresponding third rotating shafts, and the two third rotating shafts are arranged on both sides of the beam. This makes it easier to install photovoltaic panels later.

[0055] In a specific embodiment, after the short beam is adjusted vertically on the crossbeam, the vertical position of the third bolt can be tightened and secured with fasteners to secure the short beam at the desired angle. This allows for rotation and vertical angle adjustment using the third bolt. During horizontal rotation, the third bolt serves as a third rotation axis. During vertical angle adjustment (i.e., inclination adjustment), the vertical position of the third bolt secures the short beam after the inclination is adjusted by tightening it vertically.

[0056] As a specific implementation method, the base, columns, crossbeams, and short beams are all made of galvanized aluminum-magnesium main beam carbon steel. In this way, the mainstream galvanized aluminum-magnesium carbon steel material is used to achieve the best cost-effective material with high strength, easy processing, and low cost. In addition, the columns, crossbeams, and short beams serve as the upper structure, and the upper structure also uses galvanized aluminum-magnesium main beam carbon steel, and realizes a fully pre-assembled assembly method. The columns integrate the main accessories, crossbeams, and short beams. The fully pre-assembled integrated packaging reduces the over-packaging of consumables, while reducing the waste of cabinet space, and further reducing transportation costs.

[0057] A method for installing a photovoltaic support device of the present invention comprises the following steps:

[0058] S1. First fix the base 1 on the foundation,

[0059] S2. Rotate the column 2 to a vertical position and fasten it with fasteners 6;

[0060] S3. The beam 3 is rotated to a position perpendicular to the column 2 and fastened with fasteners 6;

[0061] S4. Rotate the short beam 4 horizontally to a position perpendicular to the cross beam 3, adjust the up and down angles, and then tighten and lock it with the fastener 6.

[0062] The steps of the above installation method can be summarized as "one erection, one expansion and one leveling", namely the steps of erecting the columns, expanding the beams and leveling and adjusting the inclination of the short beams. Figure 7 The following is a schematic diagram of the installation process of the photovoltaic bracket device to understand the three main steps.

[0063] In terms of design and installation, there are certain requirements for the height of agricultural supports, usually above 2 meters. At lower heights, the main columns are pre-assembled, achieving a three-step installation method of "erecting, unfolding, and leveling." After placing the columns on the foundation structure (base) and installing the first rotating shaft, the columns can be erected manually, and the columns are limited using clamps. The crossbeams are then unfolded and locked with fasteners. Finally, the short beams are unfolded for leveling and tilt adjustment. This completes the installation of the main columns, reducing the need for large equipment. At higher heights, the entire system can be assembled on the ground, and then a small traction device is used to erect the entire photovoltaic support system, further reducing labor installation costs. As a result, the cost is far lower than the lowest price in the local market.

[0064] The application scenario of this photovoltaic bracket device is mainly used in agriculture, for agricultural projects that require a high shading rate for crops, to achieve an "agriculture + photovoltaic" scenario.

The left and right photovoltaic racks are secured together by long beams 8 in combination with fasteners 6, and the front and rear photovoltaic racks are secured together by longitudinal beams 7.
