[0002] Currently, as an indispensable component of photovoltaic systems, photovoltaic brackets are receiving increasing attention from design engineers regarding how to achieve the most reasonable design of brackets while meeting basic usage conditions.

[0003] Existing fixed photovoltaic (PV) support systems typically involve fixing the columns to a flat surface and then securing the PV modules to the purlins by installing large steel components such as diagonal beams and purlins on the upper part of the columns. This support system suffers from drawbacks such as high steel consumption and high cost. Utility Model Content

[0004] The purpose of this utility model is to provide a column photovoltaic support system that can fix and install photovoltaic modules by combining columns, angle steel adapters and bolts, without the need for large steel components such as inclined beams and purlins, thus reducing steel consumption and saving costs. It effectively solves the problems of large steel consumption and high cost of existing column support systems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A photovoltaic (PV) support system includes a front column and a rear column, the rear column being taller than the front column. The front and rear columns are vertically fixed to the upper surface of the same concrete foundation. At least one angle steel adapter is provided on the upper part of each of the front and rear columns. Each angle steel adapter includes a vertically connected vertical mounting plate and a horizontal mounting plate. The horizontal mounting plate has a first elongated hole perpendicular to the length of the concrete foundation, which is connected to the backplate of the PV module via a first locking assembly. The vertical mounting plate has a second elongated hole parallel to the length of the concrete foundation. The upper parts of the front and rear columns each have a third elongated hole parallel to the length of the concrete foundation, which is connected to the second elongated hole via a second locking assembly.

[0007] Furthermore, the concrete foundation is a strip concrete foundation.

[0008] Furthermore, the concrete foundation has U-shaped anchor bolts pre-embedded and fixed at the positions corresponding to the front and rear columns. The two bolt heads of the U-shaped anchor bolts are respectively equipped with fastening components. The bottom of the front column and the bottom of the rear column are respectively fixedly connected to a support base plate. The support base plate has through holes for the bolt heads of the U-shaped anchor bolts to be inserted and installed.

[0009] Furthermore, the fastening assembly includes two nuts, two flat washers, and a spring washer.

[0010] Furthermore, a secondary pouring layer is provided between the supporting base plate and the top surface of the concrete foundation.

[0011] Furthermore, both the first locking assembly and the second locking assembly include a bolt, a nut, two flat washers, and a spring washer.

[0012] Furthermore, an L-shaped corner bracket is provided between the front column and the rear column, and one side of the corner bracket is fixed to the back plate of the photovoltaic module by the first locking component.

[0013] Furthermore, the rear column has a fourth elongated hole for installing diagonal braces, and the length of the fourth elongated hole is distributed along the height direction of the rear column.

[0014] Furthermore, an angle steel adapter is provided on the upper part of the front column and the upper part of the rear column of the side span, and the angle steel adapter fixed on the front column and the angle steel adapter fixed on the rear column are distributed on the same side.

[0016] Compared with the prior art, this utility model provides a column photovoltaic support system, which has the following beneficial effects:

[0017] This invention uses U-shaped anchor bolts on a strip-shaped concrete foundation to fix the front and rear columns, and uses a first locking assembly to fix the photovoltaic modules through angle steel adapters on the upper part of the front and rear columns, thus forming a stable column photovoltaic support system. This eliminates the need for large steel components such as inclined beams and purlins, reducing steel consumption and saving costs. Furthermore, because the angle steel adapters are equipped with first and second elongated holes distributed along a specific direction, it is easy to adjust the installation angle and position of the photovoltaic modules, improving installation convenience.

Detailed Implementation

[0026] The technical solution of this utility model will be clearly and completely described below through detailed embodiments and in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0027] Please refer to Figures 1-6This embodiment provides a photovoltaic support system, including a front column 1 and a rear column 2. The height of the rear column 2 is higher than that of the front column 1. The front column 1 and the rear column 2 are vertically fixed to the upper surface of the same concrete foundation 4. At least one angle steel adapter 3 is provided on the upper part of the front column 1 and the upper part of the rear column 2. The angle steel adapter 3 includes a vertically connected vertical mounting plate 31 and a horizontal mounting plate 32. The horizontal mounting plate 32 has a first elongated hole 321 that is perpendicular to the length direction of the concrete foundation 4. The first elongated hole 321 is connected to the back plate 51 of the photovoltaic module 5 through a first locking component 33. The vertical mounting plate 31 has a second elongated hole 311 that is parallel to the length direction of the concrete foundation 4. The upper part of the front column 1 and the upper part of the rear column 2 each have a third elongated hole 21 that is parallel to the length direction of the concrete foundation 4. The second elongated hole 311 is connected to the third elongated hole 21 through a second locking component 34. By fixing the front and rear columns to the same concrete foundation, and using the first locking assembly through angle steel adapters on the upper parts of the front and rear columns, a stable photovoltaic support system is formed. This eliminates the need for large steel components such as inclined beams and purlins, reducing steel consumption and saving costs. Furthermore, the angle steel adapters have first and second elongated holes distributed along a specific direction, facilitating adjustment of the photovoltaic module's installation angle and position, thus improving installation convenience.

[0028] In some specific implementation methods, such as Figure 1 and Figure 3 As shown, the concrete foundation 4 is a strip concrete foundation.

[0029] In some implementations, reference Figure 1 , Figure 3 and Figure 4 The concrete foundation 4 has U-shaped anchor bolts 41 pre-embedded and fixed at positions corresponding to the front column 1 and the rear column 2. Each U-shaped anchor bolt 41 has two bolt heads equipped with fastening components 42. Support plates 11 are fixedly connected to the bottom of the front column 1 and the bottom of the rear column 2, respectively. The support plates 11 have through holes for the bolt heads of the U-shaped anchor bolts 41 to pass through. As an example, the support plates 11 are made of 90mm*180mm*3mm metal plates of material S350GD-ZM275. The U-shaped anchor bolts 41 have a diameter of M12, a length of 200mm, a width of 100mm, and an exposed thread length of ≥70mm.

[0030] Specifically, such as Figure 4 As shown, the fastening assembly 42 includes two nuts 6, two flat washers 7, and a spring washer 8. The elevation of the front and rear columns is adjusted by tightening the fastening assembly.

[0031] refer to Figure 3 In some specific embodiments, a secondary pouring layer 43 is provided between the supporting base plate 11 and the top surface of the concrete foundation 4. Thus, after adjusting the elevation of the front and rear columns and completing the installation of the photovoltaic modules, a sealed protection is formed through the secondary pouring process.

[0032] In some specific implementation methods, such as Figure 5 and Figure 6 As shown, both the first locking assembly 33 and the second locking assembly 34 include a bolt 9, a nut 6, two flat washers 7, and a spring washer 8. For example, the bolt in the first locking assembly is an M8*25mm hexagonal bolt, and the flat washer is a 20mm*30mm*2.5mm large flat washer; the bolt in the second locking assembly is an M10*60mm hexagonal bolt.

[0033] As an improved implementation method, refer to Figure 3 , Figure 5 and Figure 6 A long, L-shaped corner bracket 23 is provided between the front column 1 and the rear column 2. One side of the corner bracket 23 is fixed to the back plate 51 of the photovoltaic module 5 by the first locking component 33. By adding the corner bracket, the back plate of the photovoltaic module can be strengthened, making the stress distribution more reasonable and improving the support stability, which is suitable for the installation of large-size photovoltaic modules. As an example, the corner bracket 23 uses angle steel with a cross-section of 45mm*30mm*2mm, material S350GD-ZM275 (galvanized aluminum-magnesium alloy), and a length of 1490mm.

[0034] In some implementations, reference Figure 1 , Figure 2 , Figure 5 and Figure 6 The rear column 2 has a fourth elongated hole 22 for installing the diagonal brace 24. The length of the fourth elongated hole 22 is distributed along the height direction of the rear column 2. Specifically, there is a fourth elongated hole 22 at the top and bottom of the rear column 2. A diagonal brace is installed in the fourth elongated hole of a rear column located in the side span, and two rear columns located in the middle span are connected by a diagonal brace every four spans. As an example, the diagonal brace 24 is made of 36*3 angle steel, made of Q235B, and hot-dip galvanized to 65μm thickness. The diagonal brace 24 is locked and fixed to the rear column 2 by one bolt 9, two flat washers 7, one spring washer 8, and one nut 6. The bolt is an M10*75mm hexagonal bolt.

[0035] In some specific implementations, as an example, the various components are configured as follows: Both the front and rear columns are formed from square tubular profiles with a cross-section of 40mm*40mm*2.5mm, made of S350-275ZM material, and hot-dip galvanized to 65μm thickness. The front column is 200mm high, the rear column is 322mm high, and the distance between the front and rear columns is 1395mm. The third elongated hole is an 11mm*30mm oblong hole; the fourth elongated hole is an 11mm*25mm oblong hole. The length of the concrete foundation is 1700mm. The angle steel adapter uses 63mm*4mm angle steel, made of Q235B material, hot-dip galvanized to 65μm thickness. The first elongated hole is a 9mm*30mm oblong hole, and the second elongated hole is an 11mm*30mm oblong hole. The photovoltaic module is 2465mm long. The back panel and corner bracket of the photovoltaic module each have four mounting holes for connecting the first locking component. The distance between the two mounting holes at both ends is 1400mm, and the distance between the two mounting holes in the middle is 800mm. The installation tilt angle of the photovoltaic module is 5º.

[0036] During installation, such as Figure 5 As shown, an angle steel adapter 3 is provided on the upper part of the front column 1 and the upper part of the rear column 2 of the side span, and the angle steel adapter fixed on the front column 1 and the angle steel adapter fixed on the rear column 2 are distributed on the same side, so that the photovoltaic module 5 located in the side span can be installed and fixed on one side.

[0037] refer to Figures 1-3 and Figure 6 Two angle steel adapters 3 are symmetrically provided on the upper part of the front column 1 and the upper part of the rear column 2 in the middle span, so that the photovoltaic modules 5 of the two adjacent spans can be fixed respectively, so as to achieve the purpose of installation on both sides.
