Description

Technical Field

[0001] The invention belongs to the field of photovoltaic installation, and in particular relates to a photovoltaic panel mounting bracket for a desert photovoltaic power station. Background Art

[0002] Desert photovoltaic power stations, due to their abundant solar resources and vast land potential, have become a global focus of new energy development. However, the harsh desert environment, characterized by high temperatures, strong winds, sandstorms, and shifting sand dunes, poses severe challenges to the stability, durability, and power generation efficiency of photovoltaic mounting systems.

[0003] The existing brackets for installing and fixing photovoltaic panels on sofas generally include multiple ground piles buried deep underground, and a support frame for placing photovoltaic panels is set above the multiple ground piles, and each ground pile and the support frame are connected and fixed by a support frame. The above-mentioned photovoltaic bracket has the following defects during use: in order to improve the power generation efficiency of the photovoltaic panel, the bracket will tilt the photovoltaic panel at a certain angle after fixing the photovoltaic panel. When the wind direction is facing the back of the inclined surface of the photovoltaic panel, due to the close connection between the multiple photovoltaic panels, a large flow blocking surface is formed. In this case, the photovoltaic panel will be under greater pressure, affecting the stability of the entire bracket. Due to the high incidence of strong winds in desert areas, the risk of bending and deformation of the bracket will increase, which will not only increase the burden of subsequent maintenance of the entire photovoltaic power station, but also reduce the service life of the installation bracket. Summary of the Invention

There are multiple supporting beams between two adjacent fixed beams, and the photovoltaic panel is arranged between two adjacent fixed beams.

[0013] According to a favorable embodiment, the reinforcement component 1 includes two fixing plates 1 and two fixing plates 2, the fixing plate 1 is arranged between two adjacent concrete piles on the front side, and U-shaped clips are fixedly provided at both ends of the fixing plate 1, the U-shaped clips are connected to the corresponding two support columns, and the left and right fixing plates 1 are staggered up and down, the fixing plate 2 is rotatably connected to the corresponding fixing plate 1, and the end of the fixing plate 2 away from the fixing plate 1 is fixedly connected to the corresponding support column by bolt 4 and nut 4.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1 -Attached Figure 9 This application is described in further detail.

[0030] Please refer to Figure 1-Figure 3 A photovoltaic panel mounting bracket for a desert photovoltaic power station includes multiple groups of ground pile assemblies connected to the ground and distributed front to back. The ground pile assemblies are composed of four concrete ground piles 1, and the four concrete ground piles 1 in each group of ground pile assemblies are distributed in a triangular shape, wherein three concrete ground piles 1 are located on the same straight line. A support assembly 2 is provided at the upper end of each concrete ground pile 1. The support assemblies 2 in the same group are commonly connected to a support assembly 3 for supporting the photovoltaic panel. The support assembly 3 is supported by multiple support assemblies 2 and is arranged at an angle. A reinforcement assembly 1 4 is also provided on the support assembly 2 in the same group. The reinforcement assembly 1 4 is arranged between the four concrete ground piles 1 in the ground pile assembly. Multiple groups of reinforcement assemblies 2 5 distributed left and right are commonly provided between two adjacent support assemblies 3.

[0031] During specific operation, four concrete piles 1 are arranged in a triangle and cooperate with reinforcement component 1 4 to form a triangular stable support structure to support the upper supporting component 3. At the same time, the two adjacent supporting components 3 are further connected and reinforced by reinforcement component 2 5.

[0032] See Figure 2 and Figure 5 The support assembly 2 includes two support columns 21 perpendicular to the ground and of different lengths and two diagonal braces 22 inclined to the ground and of different lengths. The upper ends of the two support columns 21 and the two diagonal braces 22 are fixedly connected with a support beam 23. The support beam 23 gradually tilts upward from front to back. Two clamps 24 distributed up and down are commonly provided near the lower ends of the two support columns 21. The clamps 24 are fixed to the outside of the concrete piles 1, and the clamp 24 located below is fixedly connected to the two diagonal braces 22. A top support member 25 for adjusting the height of the support beam 23 is also provided between the two support columns 21.

[0033] See Figure 5 The clamp 24 is composed of two bands spliced together, with bolt 1 provided at both ends of the two bands. The threaded section of bolt 1 movably passes through the support column 21 and is threadedly connected to nut 1. Bolt 2 is also provided at both ends of the two bands of the lower clamp 24. The threaded section of bolt 2 movably passes through the diagonal support frame 22 and is threadedly connected to nut 2.

[0034] See Figure 5 To eliminate the problem of uneven rear end surfaces of two adjacent concrete piles 1 after installation on the ground, resulting in different heights of the two adjacent support beams 23, the supporting member 25 includes a connecting beam 251 fixedly disposed between the two support columns 21. An adjusting bolt 252 is threadedly mounted on the connecting beam 251, and the lower end of the adjusting bolt 252 movably engages the upper end surface of the concrete pile 1. Rotating the adjusting bolt 252 changes the length by which the lower end of the adjusting bolt 252 protrudes from the underside of the connecting beam 251. The longer the lower end of the adjusting bolt 252 protrudes, the higher the height of the support beam 23. Thus, the height of the two adjacent support beams 23 can be adjusted by rotating the adjusting bolt 252, eliminating the problem of subsequent installation difficulties caused by the height difference between the two adjacent concrete piles 1.

[0035] During the specific operation, the two support columns 21 and the two diagonal braces 22 are pre-installed on the two clamps 24. Then, after the entire support assembly 2 is manually moved to a certain height, the two clamps 24 are put on the surface of the concrete pile 1. The lower end of the adjusting bolt 252 at the lower end of the support beam 23 contacts the upper end of the concrete pile 1 to prevent the support assembly 2 from sliding down as a whole.

[0036] See Figure 2 and Figure 4The reinforcement component 4 includes two fixing plates 41 and two fixing plates 2 42. The fixing plate 1 41 is arranged between the two adjacent left and right concrete piles 1 on the front side. U-shaped card plates 43 are fixedly provided at both ends of the fixing plate 1 41. The U-shaped card plates 43 are connected to the corresponding two support columns 21, and the left and right fixing plates 1 41 are staggered up and down. The fixing plate 2 42 is rotatably connected to the corresponding fixing plate 1 41, and the end of the fixing plate 22 away from the fixing plate 1 41 is fixedly connected to the corresponding support column 21 by a bolt 4 and a nut 4.

[0037] See Figure 4 , a thread groove (not shown in the figure) is opened on the side of the two pins of the U-shaped card plate 43 close to the corresponding support column 21, and a bolt three is rotatably provided on the support column 21. The threaded section of the bolt three movably passes through the support column 21 and is threadedly connected to the thread groove on the corresponding pin of the U-shaped card plate 43.

[0038] During specific operation, the four concrete piles 1 in the same pile assembly are distributed with three in front and one in the back. At the same time, the fixing plate 1 41 connects and reinforces the three concrete piles 1 in the same row on the front side, and the two fixing plates 2 42 connect and reinforce the concrete piles 1 on the back side with the two concrete piles 1 on the left and right sides on the front side, so that the overall triangular stable structure is formed, which improves the stability of the entire bottom of the mounting bracket.

[0039] See Figure 1 、 Figure 2 、 Figure 5 and Figure 6 The supporting assembly 3 includes multiple supporting beams 31 and three fixed beams 32 with an I-shaped cross-section. Multiple supporting beams 31 are fixedly arranged on the upper side of the support beams 23 in the same group and are evenly distributed along the length direction of the support beams 23. Three fixed beams 32 are fixedly arranged on the upper side of the support beams 23 in the same group and are evenly distributed along the length direction of the support beams 23. There are multiple supporting beams 31 between two adjacent fixed beams 32, and the photovoltaic panel is arranged between two adjacent fixed beams 32.

[0040] During specific operation, the photovoltaic panel is engaged between two adjacent fixing beams 32 and fixed by external bolts 5, while the lower side of the photovoltaic panel is supported by the corresponding supporting beam 31.

[0041] Among them, the support column 21, the diagonal bracing beam 22, the support beam 23, and the fixed beam 32 are all channel steel structures.

[0042] See Figure 2 、 Figure 3 and Figure 7The reinforcement component 2 5 includes a tensioning plate 1 51, a tensioning plate 2 52 and a tensioning plate 3 53, which are respectively rotatably connected to the lower sides of the three fixed beams 32. The tensioning plate 1 51 and the corresponding tensioning plate 2 52, as well as the tensioning plate 2 52 and the corresponding tensioning plate 3 53 are connected by a connecting portion 54. The side of the tensioning plate 3 53 away from the corresponding fixed beam 32 is fixedly connected to the lowest fixed beam 32 on the next group of supporting components 3.

[0043] During operation, multiple supporting beams 31, support beams 23, and three fixed beams 32 above the same concrete pile 1 together form a supporting frame 6. Since all supporting frames 6 in this solution are positioned with the front lower and the back higher, when the wind direction is from back to front (in this state, the wind resistance experienced by the entire supporting frame 6 is the greatest), the back of the supporting frame 6 and the photovoltaic panels on its surface will be subjected to a very large thrust, generating a thrust from back to front on the supporting frame 6, causing it to tend to flip outward. The tensioning plates 3 53 between two adjacent supporting frames 6 can offset some of the wind resistance, thereby further improving the wind resistance of the entire mounting bracket. Furthermore, the tensioning plates 1 51, 2 52, and 3 53 are simultaneously connected to the three fixed beams 32 in the corresponding supporting assembly 3, and by tightening the fixed beams 32, the photovoltaic panels mounted on the fixed beams 32 are further locked.

[0044] See Figure 7 and Figure 8 In order to ensure that the tensioning plate 1 51 and the tensioning plate 2 52 can tighten their respective fixed beams 32 through the tensioning plate 3 53, a strip hole is opened on the tensioning plate 1 51 and the tensioning plate 2 52, and the connecting part 54 includes a tensioning screw 541 rotatably set in the strip hole, and the tensioning screw 541 is threadedly connected to a tensioning block 542, and the tensioning block 542 is slidably set in the strip hole. The tensioning plate 1 51 and the tensioning plate 2 52 are respectively hinged to the corresponding tensioning block 542.

[0045] During specific operation, after the tensioning plate 1 51, the tensioning plate 2 52 and the tensioning plate 3 53 are installed, when the tensioning plate 1 51 is tightened, the corresponding tensioning screw 541 is rotated to make the tensioning block 542 drive the tensioning plate 1 51 to move slightly relative to the tensioning plate 2 52, and the tensioning plate 1 51 and the tensioning plate 2 52 are tightened. In the same way, the tensioning plate 2 52 is tightened relative to the tensioning plate 3 53, so that the tension transmission between each other is more direct, the interaction effect is better, and the overall shaking is reduced to a greater extent.
