Description

Technical field

[0001] The present invention relates to the technical field of photovoltaic systems, and in particular to a conveniently installed photovoltaic ballast system and an installation process that uses both long and short sides. [Background Technology]

[0002] Distributed photovoltaics are increasingly being used in areas such as urban building roofs and industrial and commercial plants. The roof structures and load-bearing capacities of these locations vary, and many buildings cannot withstand the weight of traditional large ballasts. Portable ballasts can flexibly adjust the weight and position of the ballast according to the actual load-bearing capacity of the roof and the layout requirements of the photovoltaic system, enabling safe and efficient installation. For example, in rooftop photovoltaic renovation projects in old urban communities, since most roofs are lightweight structures, traditional ballast methods may cause damage to the roofs. However, photovoltaic portable ballasts can complete the installation of the photovoltaic system without damaging the roof structure. As photovoltaic portable ballasts have been recognized by the general public, the following problems exist:

[0003] 1. The environment of the project sites developed subsequently has also become diverse. In response to such changing environments, it is necessary to adjust the tilt angle of photovoltaic modules at multiple angles to maximize power generation.

[0004] 2. People's demand for the power of photovoltaic modules is constantly increasing. When the power of photovoltaic modules increases, the specifications of the modules will also become larger. As a result, multiple sizes and specifications of modules will appear. The current existing technology can only design photovoltaic support systems with multiple specifications to meet the needs of this change.

[0005] 3. Traditional aluminum alloy design solutions are mainly based on locking the short sides of the components, which leads to the risk of deformation of photovoltaic components; the carbon steel solution cannot meet the unitization of the entire roof component.

[0006] 4. With the increasing demand for manpower and material resources, customers are placing increasing emphasis on construction efficiency and cost. Traditional design solutions cannot meet the requirements of modularization and convenient pre-assembly of the entire product set, and they also have problems such as long production cycles and high costs.

[0007] In view of this, the inventors of this case conducted in-depth research on the above-mentioned issues, which led to the creation of this case. [Summary of the invention]

[Specific implementation method]

[0052] In order to better understand the technical solution of the present invention, the technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0053] In the prior art, a photovoltaic module 100 generally includes a long side 101 and a short side 102 .

[0054] Reference Attachment Figure 1-25 As shown, the present invention provides a conveniently installed photovoltaic ballast system that is shared by both long and short sides, including a ballast bottom beam 1, a front column 2, a rear column 3, and a shared middle and side pressure combination 4.

[0055] The ballast bottom beam 1 includes a bottom plate 11 , a first side plate 12 and a second side plate 13 oppositely arranged on the bottom plate 11 , and an assembly platform 14 fixed between the first side plate 12 and the second side plate 13 .

[0056] The front column 2 is installed on the assembly platform 14. The front column 2 includes a long side pressure portion 21 for cooperating with the common middle side pressure combination 4 to lock the long side of the photovoltaic component, and a short side pressure portion 22 for cooperating with the common middle side pressure combination 4 to lock the short side of the photovoltaic component. The long side pressure portion 21 and the short side pressure portion 22 are arranged as one body, and the top surface of the front column 2 is provided with a vertical plate 23 for limiting the photovoltaic component; by cooperating with the common middle side pressure combination 4 on the long and short side pressure portions 22 of the integrated front column 2, the universal locking of the long and short sides of the photovoltaic component is achieved, which solves the problem that the traditional solution can only fix a single side.

[0057] The rear column 3 includes a basic column 31, which is installed on the assembly platform 14. The top surface of the basic column 31 is formed with a first T-shaped slot 311; the T-shaped slot design of the rear column 3 facilitates rapid installation and adjustment with the shared middle and side pressure combination 4. The overall structure has a high degree of modularity and can be pre-assembled and transported, which significantly improves on-site installation efficiency. At the same time, it adapts to components of different specifications and angle requirements and reduces production costs.

[0058] The shared middle and side pressure assembly 4 includes a basic clamping block 41 for clamping with the front column 2 and the rear column 3 , and a shared middle and side pressure block 42 that cooperates with the basic clamping block 41 to press the long and short sides of the photovoltaic module 100 .

[0059] The convenient installation photovoltaic ballast system of the present invention, which shares the long and short sides, can realize the multi-angle adjustment of the photovoltaic module 100 and is applicable to photovoltaic modules 100 of multiple sizes (length, width, etc.) through the free assembly of multiple modules; the front column 2 and the rear column 3 can be pre-assembled with the ballast bottom beam 1 and can be directly unfolded and fixed on site; the bottom beam connector 6 can be selected as needed to save assembly steps; by sharing the middle and side pressure combination 4, the photovoltaic module panel can be installed horizontally or vertically.

[0060] In the present invention, first bolt holes 15 are defined at one end of each of the first and second side panels 12 and 13, and second bolt holes 211 are defined in the front pillar 2. The front pillar 2 is locked between the first and second side panels 12 and 13 via a first locking unit 51. Third bolt holes 16 are defined in each of the first and second side panels 12 and 13, and fourth bolt holes 312 are defined at the bottom of the foundation pillar 31. The foundation pillar 31 is locked between the first and second side panels 12 and 13 via a second locking unit 52. Each of the first and second side panels 12 and 13 also defines an eighth bolt hole 18, spaced apart from the third bolt hole 16. When the short side is pressed, the second locking unit 52 locks the rear column 3 to the ballast bottom beam 1 through the fourth bolt hole 312 and the third bolt hole 16. When the long side is pressed, the second locking unit 52 locks the rear column 3 to the ballast bottom beam 1 through the fourth bolt hole 312 and the eighth bolt hole 18. This allows the bolt holes of the rear column 3 and the ballast bottom beam 1 to be freely switched when the photovoltaic module 100 is pressed on the long and short sides. The standardized design of the bolt holes and locking units makes the pre-assembly and on-site locking of the front and rear columns 3 and the ballast bottom beam 1 more convenient. The division of labor between the first locking unit 51 and the second locking unit 52 ensures structural stability, and the bolt connection method simplifies the installation process, reduces tool dependence, and is suitable for different construction conditions.

[0061] In the present invention, the top surface of the long-side pressure portion 21 is formed with a third T-shaped slot 212 for mating with the base block 41. The top surface of the short-side pressure portion 22, which serves as a support surface for the photovoltaic module, is formed with a fourth T-shaped slot 221 for mating with the base block 41. During assembly, the second T-shaped block 411 of the base block 41 slides into the third T-shaped slot 212 or the fourth T-shaped slot 221. The cooperation between the third T-shaped slot 212, the fourth T-shaped slot 221, and the base block 41 achieves a "slide-in" installation, reducing alignment difficulty and improving compression efficiency. The integrated design of the vertical plate 23, the photovoltaic module support surface and the T-slot allows the basic block 41 to be fixed to the front column 2 only by the force of the photovoltaic module 100 on the vertical plate 23, so that no additional fixings are required to lock the front column 2 and the basic block 41; at the same time, it ensures the precise positioning of the long and short sides of the photovoltaic module 100, and is compatible with different modules, thereby enhancing versatility.

[0062] In the present invention, the front column 2 also includes a splicing portion 24 integrally formed with the long-side pressure portion 21. The splicing portion 24 includes a guide slot 241 and a bolt slot 242. The guide slot 241 is arranged at an angle and communicates with the bolt slot 242. The inclined communication between the guide slot 241 and the bolt slot 242 of the splicing portion 24 makes the splicing process of adjacent ballast bottom beams 1 smoother. The bolts automatically slide into the predetermined bolt slots 242, reducing manual adjustments and improving the efficiency of multi-module expansion. It is particularly suitable for the rapid installation of large-span roofs.

[0063] In this invention, at least two first conductive spikes 25 are provided on one side of the front column 2, and at least two second conductive spikes 26 are provided on the photovoltaic module support surface. The first conductive spikes 25 are directly embedded in the first side plate 12 of the ballast base beam 1, and the second conductive spikes 26 are directly embedded in the frame of the photovoltaic module 100. These spikes pierce the oxide layer to achieve a reliable conductive connection, eliminating the need for a separate grounding step and improving system safety. The integrated design of the conductive spikes and the structure eliminates the need for external grounding wires, simplifies wiring, and reduces material costs.

[0064] In the present invention, as shown in the attached Figure 15 As shown, in the case of a single-slope photovoltaic system, two adjacent ballast bottom beams 1 are connected via a front column 2; the other ends of the first side panel 12 and the second side panel 13 are each provided with a fifth bolt hole 17. The third locking unit 53 passes through the fifth bolt hole 17 of the first side panel 12, the bolt slot 242, and the fifth bolt hole 17 of the second side panel 13 in sequence to lock the two adjacent ballast bottom beams 1. Directly connecting adjacent bottom beams via the front column 2 forms a seamless connection for a single-slope structure, reducing the number of connectors and overall weight and cost. The through-type fixation of the third locking unit 53 ensures connection strength, adapts to the roof's load-bearing limitations, and maintains a compact structure.

[0065] In the present invention, as shown in the attached Figure 16 As shown, when it is a double-slope photovoltaic system, two adjacent ballast bottom beams 1 are connected by a bottom beam connector 6; the bottom beam connector 6 includes a first connecting side plate 61 and a second connecting side plate 62, and the first connecting side plate 61 is provided with a sixth bolt hole 63 and a seventh bolt hole 64, and the second connecting side plate 62 is provided with a sixth bolt hole 63 and a seventh bolt hole 64; the third locking unit 53 passes through the sixth bolt hole 63 of the first connecting side plate 61, the bolt groove 242, and the sixth bolt hole 63 of the second connecting side plate 62 in sequence to lock the front column 2 of the first ballast bottom beam 1 with the bottom beam connector 6; the fourth locking unit 54 passes through the seventh bolt hole 64 of the first connecting side plate 61, the bolt groove 242, and the sixth bolt hole 63 of the second connecting side plate 62 in sequence to lock the front column 2 of the second ballast bottom beam 1 with the bottom beam connector 6. When the photovoltaic module is double-slope, the two adjacent ballast bottom beams 1 need to be connected through the bottom beam connector 6. The bottom beam connector 6 is connected with four bolt holes. The bottom beam connector 6 is equipped with a third locking unit 53 and a fourth locking unit 54 to fix and lock the two adjacent ballast bottom beams 1 respectively. Slide the bolt of the third locking unit 53 into the bolt groove 242 along the guide groove 241 of the first front column 2, then manually adjust the bottom beam connector 6 and lock it, and then align the guide groove 241 of the front column 2 of the second ballast bottom beam 1 with the bolt of the fourth locking unit 54 and place it obliquely into the bolt groove 242, and then lock it. The split design of the bottom beam connector 6 supports the flexible construction of the double-slope structure. The multi-position adaptation of the sixth bolt hole 63 and the seventh bolt hole 64 allows splicing at different angles, expanding the applicable scenarios of the system.

[0066] In the present invention, rear columns 3 also include elevated columns 32, which are detachably mounted on the top surface of base columns 31. A second T-shaped slot 321 is formed on the top surface of elevated columns 32. The detachable design of elevated columns 32 enables quick switching between 10° and 15° inclination angles, meeting the requirements for optimized power generation under varying lighting conditions. The stacked structure of base columns 31 and elevated columns 32 eliminates the need for complete bracket replacement, reducing spare part costs and increasing system flexibility.

[0067] In the present invention, a fixing slot 313 is provided on the side of the base column 31. The heightened column 32 extends downward toward the side of the front column 2 to form a fixing hook plate 322, which cooperates with the fixing slot 313. A first T-shaped block 323 is fixed to the bottom surface of the heightened column 32 for cooperating with the first T-shaped slot 311. The mechanical interlocking of the fixing hook and the fixing slot 313 ensures the wind-resistant and earthquake-resistant stability of the heightened column 32, preventing displacement after tilt adjustment. The first T-shaped block 323 precisely mates with the first T-shaped slot 311 of the base column 31, enhancing the vertical load-bearing capacity and avoiding the risk of hidden cracks in the component due to bracket deformation.

[0068] In the present invention, a cable slot 314 is further provided on the side of the basic column 31 .

[0069] In the present invention, in order to further improve the connection stability between the basic column 31 and the heightened column 32, a first through hole 314 is further formed on the side of the basic column 31, and a second through hole 324 is further formed on the side of the heightened column 32 facing the front column 2, and is locked by the sixth locking unit 56.

[0070] In the present invention, the base block 41 includes a second T-shaped block 411 at the bottom. The shared middle-side pressure block 42 includes a pressure plate 421, a first vertical plate 422, and a second vertical plate 423. The first vertical plate 422 and the second vertical plate 423 are fixedly connected to the bottom surface of the pressure plate 421 and are arranged opposite each other. The shared middle-side pressure block 42 and the base block 41 are connected by a fifth locking unit 55. The second T-shaped block 411 of the base block 41 and the vertical plate of the shared middle-side pressure block 42 form a double-point compression, evenly distributing the force on the photovoltaic module, reducing frame deformation, and extending service life. At the same time, the pressure plate 421 contacts the module edge over a large area, improving wind-up resistance.

[0071] The present invention also includes a cement ballast assembly 7; the cement ballast assembly 7 includes a rotating clamp 71, a C-shaped steel beam 72, and a cement pressure block 73; the rotating clamp 71 includes an integrally arranged hand-held portion 711, an extension portion 712, and a third T-shaped clamp 713, a long hole 721 is provided on the C-shaped steel beam 72, and a fifth T-shaped slot 141 is formed on the side of the assembly platform 14 facing the bottom plate 11 for the third T-shaped clamp 713 to be inserted into. The design of the rotating clamp 71 and the long hole 721 of the C-shaped steel beam 72 allows the ballast position to be adjusted steplessly to meet different counterweight requirements. The rotation locking mechanism of the fifth T-shaped slot 141 and the third T-shaped clamp 713 enables the cement pressure block 73 to be quickly installed without welding, reduces the difficulty of construction, and facilitates later maintenance and replacement.

[0072] In the present invention, a first flange 121 is provided on the first side panel 12, and a second flange 131 is provided on the second side panel 13. The first flange 121 and the second flange 131 enhance the lateral bending strength of the ballast base beam 1, preventing deformation under prolonged load. They also provide a mounting reference surface for the cement ballast assembly 7, improving the overall structural accuracy.

[0073] The present invention also includes a rubber pad 8 mounted on the bottom surface of the ballast beam 1. The top surface of the rubber pad 8 is formed with a first hook 81 and a second hook 82. A third flange 111 and a fourth flange 112 are formed outwardly on either side of the base plate 11. The first hook 81 engages with the third flange 111, and the second hook 82 engages with the fourth flange 112. The hooks of the rubber pad 8 tightly engage with the flanges of the base plate 11, preventing the ballast beam 1 from sliding and shifting, while also buffering vibration and noise and protecting the roof structure. The rubber material is highly weather-resistant and adapts to temperature fluctuations, extending the system's service life. Furthermore, it requires no gluing during installation, making it environmentally friendly and easy to replace.

[0074] The beneficial technical effects of the present invention are further illustrated below through eight embodiments.

The shared middle side pressure block and the basic clamping block are locked by the fifth locking unit. When the photovoltaic module is tilted at a 10° angle, the basic clamping block is clamped with the basic column. When the photovoltaic module is tilted at a 15° angle, the basic clamping block is clamped with the heightened column. When it is necessary to fix the long side of the photovoltaic module, the basic card block is clamped with the long side side pressure part, the common middle side pressure block presses the long side, and the common middle side pressure block and the basic card block are locked by the fifth locking unit; when it is a photovoltaic module with a tilt angle of 10°, the basic card block is clamped with the basic column, and when it is a photovoltaic module with a tilt angle of 15°, the basic card block is clamped with the heightened column.
