Description

Technical Field

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

[0002] Due to its rich solar energy resources and vast land potential, desert photovoltaic power stations have become the focus of global new energy development. However, the harsh conditions in the desert environment, such as high temperature, strong wind, sandstorms, and dune movement, pose severe challenges to the stability, durability, and power generation efficiency of the photovoltaic support system.

[0003] Existing brackets for mounting and fixing photovoltaic panels in the desert generally include multiple ground piles buried deep in the ground. Above the multiple ground piles, there is a support bracket for placing the photovoltaic panels, and each ground pile is connected and fixed to the support bracket through a support frame. The above photovoltaic support has the following defects in the use process: In order to improve the power generation efficiency of the photovoltaic panels, the support will tilt the photovoltaic panels at a certain angle after fixing them. When the wind direction is directly opposite to the back of the inclined surface of the photovoltaic panel, due to the tight connection between multiple photovoltaic panels, a large flow resistance surface is formed. In this case, the photovoltaic panels will bear a large pressure, affecting the stability of the entire support. Since there are many strong wind days in desert areas, this will increase the risk of the support bending and deforming, not only increasing the burden of subsequent maintenance of the entire photovoltaic power station, but also reducing the service life of the mounting bracket. Summary of the Invention

[0004] In order to solve the above problems, the present invention provides a mounting bracket for photovoltaic panels in a desert photovoltaic power station, which is used to solve the problem that the stability of the photovoltaic panel fixing bracket is low and it is easily compressed and deformed in strong wind weather in desert areas.

[0005] In order to achieve the above object, the embodiments of the present application provide the following technical solutions: The present invention provides a mounting bracket for photovoltaic panels in a desert photovoltaic power station, including multiple groups of ground pile components connected to the ground and distributed front and back. Each ground pile component is composed of four concrete ground piles, and the four concrete ground piles in each group of ground pile components are distributed in a triangular shape. At the upper end of the concrete ground pile, there is a support component. On the support components in the same group, there is a support bracket component for supporting the photovoltaic panels connected together. The support bracket component is supported by multiple support components and is inclined.

[0006] On the support components in the same group, there is also a first reinforcement component. The first reinforcement component is arranged between the four concrete ground piles in the ground pile component, and the four concrete ground piles are further connected through the first reinforcement component to form a triangular support structure.

[0007] There are multiple sets of reinforcement components two distributed left and right between two adjacent front and rear supporting components. The reinforcement components two are used to connect two adjacent front and rear supporting components to each other, and the head and tail positions of two adjacent front and rear supporting components can generate mutual acting forces for connection and support.

[0008] According to a preferred embodiment, the support component includes two support columns perpendicular to the ground with different lengths and two inclined strut beams inclined to the ground with different lengths. The upper ends of the two support columns and the two inclined strut beams are fixedly connected with a support beam. The support beam gradually inclines upward from front to back. There are two upper and lower distributed hoop fasteners arranged between the two support columns near the lower end. The hoop fasteners are fixed outside the concrete piles, and the lower hoop fastener is fixedly connected with the two inclined strut beams. There is also a top support member arranged between the two support columns for adjusting the height of the support beam.

[0009] According to a preferred embodiment, the top support member includes a connecting beam fixedly arranged between the two support columns. An adjusting bolt is threadedly arranged on the connecting beam, and the lower end of the adjusting bolt is movably abutted against the upper end face of the concrete pile.

[0010] According to a preferred embodiment, the hoop fastener is composed of two spliced hoop bands. Bolts one are arranged at both ends of the two hoop bands. The threaded sections of the bolts one movably penetrate through the support column and are threadedly connected with nuts one.

[0011] According to a preferred embodiment, bolts two are also arranged at both ends of the two hoop bands of the lower hoop fastener. The threaded sections of the bolts two movably penetrate through the inclined support frame and are threadedly connected with nuts two.

[0012] According to a preferred embodiment, the supporting component includes multiple supporting beams and three fixed beams with an I-shaped cross-section. Multiple supporting beams evenly distributed along the length direction thereof are fixedly arranged on the upper side of the support beam in the same group. The three fixed beams are fixedly arranged on the upper side of the support beam in the same group and are evenly distributed along the length direction of the support beam. There are multiple supporting beams between two adjacent fixed beams. The photovoltaic panel is arranged between two adjacent fixed beams.

[0013] According to a preferred embodiment, the reinforcement component one includes two fixing plates one and two fixing plates two. The fixing plates one are arranged between two adjacent front concrete piles. U-shaped clamping plates are fixedly arranged at both ends of the fixing plates one. The U-shaped clamping plates are connected with the corresponding two support columns, and the left and right fixing plates one are distributed vertically and staggeredly. The fixing plates two are rotatably connected with the corresponding fixing plates one, and the end of the fixing plates two far away from the fixing plates one is fixedly connected with the corresponding support column through bolts four and nuts four.

[0014] According to an advantageous embodiment, threaded grooves are formed on one side of the two pins of the U-shaped clamping plate close to the corresponding support columns, and a bolt three is rotatably arranged on the support column. The threaded section of the bolt three movably penetrates through the support column and is threadedly connected to the threaded groove on the corresponding pin of the U-shaped clamping plate.

[0015] According to an advantageous embodiment, the second reinforcement assembly includes a tensioning plate one, a tensioning plate two, and a tensioning plate three that are respectively rotatably connected to the lower sides of the three fixed beams. The tensioning plate one and the corresponding tensioning plate two, and the tensioning plate two and the corresponding tensioning plate three are all connected through a connecting portion. The side of the tensioning plate three away from the corresponding tensioning plate three is fixedly connected to the lowermost fixed beam of the next set of supporting assemblies.

[0016] According to an advantageous embodiment, strip-shaped holes are formed on both the tensioning plate one and the tensioning plate two. The connecting portion includes a tensioning screw rod rotatably arranged in the strip-shaped hole. A tensioning block is threadedly connected to the tensioning screw rod. The tensioning block is slidably arranged in the strip-shaped hole, and the tensioning plate one and the tensioning plate two are respectively hinged to the corresponding tensioning blocks.

[0017] Compared with the prior art, a photovoltaic panel installation bracket for a desert photovoltaic power station provided by an embodiment of the present invention has the following beneficial effects: 1. In the present invention, the ground pile assembly adopts four concrete ground piles distributed in a triangle, combined with the first reinforcement assembly to form a triangular stable support structure. The first fixing plate is horizontally connected to the left and right adjacent concrete ground piles on the front side, and the second fixing plate is obliquely connected to the rear concrete ground pile and the front concrete ground pile, forming a multi-directional tension network. Through the rigid connection of the U-shaped clamping plate and the bolt three, the displacement risk between the ground piles is eliminated, and the anti-wind and sand impact ability at the bottom of the bracket is significantly enhanced.

[0018] 2. In the present invention, after the tensioning plate one, the tensioning plate two, and the tensioning plate three in the second reinforcement assembly are connected, they are connected to the lowermost fixed beam in the adjacent supporting assembly. When strong wind impacts from the back of the photovoltaic panel, the tensioning plate three converts the wind resistance into a backward pulling force, which is transmitted to the corresponding fixed beams through the tensioning plate one and the tensioning plate two, forming a reverse balance force, which can greatly improve the overall wind resistance performance.

Detailed implementation manners

[0029] The following will Figure 1 - with reference to the Figure 9 make a further detailed description of the present application.

[0030] Please refer to Figures 1-3 , a photovoltaic panel installation bracket for a desert photovoltaic power station, including multiple groups of ground pile components connected to the ground and distributed front and back. The ground pile components are composed of four concrete ground piles 1, and the four concrete ground piles 1 in each group of ground pile components are distributed in a triangular shape, with three of the concrete ground piles 1 on the same straight line. A support component 2 is provided at the upper end of each concrete ground pile 1. A supporting component 3 for supporting the photovoltaic panel is commonly connected to the support components 2 in the same group. The supporting component 3 is supported by multiple support components 2 and is inclined. A first reinforcement component 4 is also provided on the support components 2 in the same group. The first reinforcement component 4 is arranged between the four concrete ground piles 1 in the ground pile component. Multiple groups of second reinforcement components 5 distributed left and right are commonly provided between two adjacent supporting components 3 front and back.

[0031] During specific operation, a stable triangular support structure is formed by the triangular arrangement of the four concrete ground piles 1 and the cooperation with the first reinforcement component 4 to support the upper supporting component 3. At the same time, the adjacent two supporting components 3 are further connected and reinforced by the second reinforcement component 5.

[0032] Refer to 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 to a support beam 23 together. The support beam 23 slopes upward gradually from front to back. Two hoop fasteners 24 are arranged vertically at a position near the lower end between the two support columns 21. The hoop fasteners 24 are fixed outside the concrete piles 1, and the lower hoop fastener 24 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 arranged between the two support columns 21.

[0033] Refer to Figure 5 , the hoop fastener 24 is composed of two spliced hoop bands. Bolts I are arranged at both ends of the two hoop bands. The threaded sections of the bolts I pass through the support column 21 movably and are threadedly connected to nuts I. Bolts II are also arranged at both ends of the two hoop bands of the lower hoop fastener 24. The threaded sections of the bolts II pass through the diagonal brace 22 movably and are threadedly connected to nuts II.

[0034] Refer to Figure 5 , in order to eliminate the problem that the heights of adjacent two support beams 23 are different due to the uneven end faces of adjacent two concrete piles 1 after being installed on the ground, the top support member 25 includes a connecting beam 251 fixedly arranged between the two support columns 21. An adjusting bolt 252 is arranged on the connecting beam 251 in a threaded manner. The lower end of the adjusting bolt 252 abuts against the upper end face of the concrete pile 1 movably. Rotating the adjusting bolt 252 can change the length of the lower end of the adjusting bolt 252 protruding from the lower side 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 heights of adjacent two support beams 23 can be adjusted by rotating the adjusting bolt 252 to eliminate the problem of difficult subsequent installation due to the height difference between adjacent two concrete piles 1.

[0035] During specific operation, the two support columns 21 and the two diagonal braces 22 are pre-installed on the two hoop fasteners 24. Then, after the whole support assembly 2 is manually carried to a certain height, the two hoop fasteners 24 are sleeved 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 abuts against and limits the upper end of the concrete pile 1 to prevent the whole support assembly 2 from sliding down.

[0036] Refer to Figure 2 and Figure 4, the first reinforcement component 4 includes two first fixing plates 41 and two second fixing plates 42. The first fixing plates 41 are arranged between the left and right adjacent concrete piles 1 on the front side. U-shaped clamping plates 43 are fixedly arranged at both ends of the first fixing plates 41. The U-shaped clamping plates 43 are connected to the corresponding two support columns 21, and the left and right first fixing plates 41 are distributed in a staggered manner up and down. The second fixing plates 42 are rotatably connected to the corresponding first fixing plates 41, and one end of the second fixing plates 42 away from the first fixing plates 41 is fixedly connected to the corresponding support column 21 through the fourth bolt and the fourth nut.

[0037] Refer to Figure 4 , threaded grooves (not shown in the figure) are provided on one side of the two pins of the U-shaped clamping plate 43 close to the corresponding support column 21. A third bolt is rotatably arranged on the support column 21. The threaded section of the third bolt penetrates through the support column 21 movably and is threadedly connected to the threaded groove on the pin of the corresponding U-shaped clamping plate 43.

[0038] During specific operation, the four concrete piles 1 in the same pile component are distributed with three in the front and one in the rear. At the same time, the first fixing plates 41 connect and reinforce the three concrete piles 1 in the same row on the front side. The two second fixing plates 42 connect and reinforce the concrete pile 1 at the rear with the left and right concrete piles 1 on the front side, so as to form a triangular stable structure as a whole, improving the stability under the entire installation bracket.

[0039] Refer to Figure 1 、 Figure 2 、 Figure 5 and Figure 6 , the supporting component 3 includes a plurality of supporting beams 31 and three fixing beams 32 with an I-shaped cross-section. A plurality of supporting beams 31 are fixedly arranged on the upper side of the supporting beam 23 in the same group and are evenly distributed along its length direction. The three fixing beams 32 are fixedly arranged on the upper side of the supporting beam 23 in the same group and are evenly distributed along the length direction of the supporting beam 23. There are a plurality of supporting beams 31 between adjacent two fixing beams 32. The photovoltaic panel is arranged between adjacent two fixing beams 32.

[0040] During specific operation, the photovoltaic panel is clamped between adjacent two fixing beams 32 and fixed by an external fifth bolt. At the same time, 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 supporting beam 23, and the fixing beam 32 are all made of channel steel structures.

[0042] Refer to Figure 2 、 Figure 3 and Figure 7, the second reinforcement component 5 includes a tension plate one 51, a tension plate two 52, and a tension plate three 53 that are respectively rotatably connected to the lower sides of the three fixed beams 32. The tension plate one 51 and the corresponding tension plate two 52, as well as the tension plate two 52 and the corresponding tension plate three 53, are all connected through a connecting part 54. The side of the tension plate three 53 away from the corresponding fixed beam 32 is fixedly connected to the lowermost fixed beam 32 in the next set of supporting components 3.

[0043] During specific operation, multiple supporting beams 31, supporting beams 23, and three fixed beams 32 above the same concrete pile 1 together form a supporting frame 6. Since all the supporting frames 6 in this solution are in a posture of being lower in the front and higher in the rear, when the wind direction is from the rear to the front (in this state, the wind resistance received by the entire supporting frame 6 is the largest), a very large thrust will be applied to the back of the supporting frame 6 and the photovoltaic panels on its surface, generating a thrust from the rear to the front on the supporting frame 6, causing the supporting frame 6 to have a tendency to turn outward. Between two adjacent supporting frames 6, the tension plate three 53 can be used to offset part of the wind resistance, thereby further improving the wind resistance performance of the entire installation bracket. Moreover, the tension plate one 51, the tension plate two 52, and the tension plate three 53 are simultaneously connected to the three fixed beams 32 in the corresponding supporting component 3, and the photovoltaic panels installed on the fixed beams 32 are further locked by tightening the fixed beams 32.

[0044] Refer to Figure 7 and Figure 8 , in order to ensure that the tension plate one 51 and the tension plate two 52 can tighten their respective fixed beams 32 through the tension plate three 53, strip holes are provided on both the tension plate one 51 and the tension plate two 52. The connecting part 54 includes a tension screw 541 rotatably arranged in the strip hole. A tension block 542 is threadedly connected to the tension screw 541. The tension block 542 is slidably arranged in the strip hole. The tension plate one 51 and the tension plate two 52 are respectively hinged to the corresponding tension blocks 542.

[0045] During specific operation, when the tension plate one 51, the tension plate two 52, and the tension plate three 53 are installed, when tightening the tension plate one 51, by rotating the corresponding tension screw 541, the tension block 542 drives the tension plate one 51 to slightly move relative to the tension plate two 52, and the tension plate one 51 and the tension plate two 52 are tightened. By the same method, the tension plate two 52 is tightened relative to the tension plate three 53, making the force transmission between them more direct, the interaction effect better, and greatly reducing the overall shaking.
