Description

Technical Field

[0001] This invention relates to ballast photovoltaic systems, and more particularly to an adjustable ballast photovoltaic support module and system. Background Technology

[0002] With the vigorous development of the photovoltaic industry, large-scale ground-mounted power stations are facing increasing constraints, while the distributed photovoltaic industry continues to expand, with cement flat roofs accounting for an increasingly larger proportion of distributed photovoltaic systems. As the demand for cement ballast photovoltaic systems continues to grow, component specifications are becoming more diverse, and environmental factors at project sites are also influencing the market, various existing ballast photovoltaic structures can no longer meet market demands. Currently, the existing ballast photovoltaic system technology mainly focuses on fixing the short side of the photovoltaic modules. As power requirements increase, the size of photovoltaic modules also increases, leading to a greater risk of insufficient support for the modules. Furthermore, existing technologies are mainly divided into two categories: one uses carbon steel ballast, with each of the front and rear columns utilizing cement counterweights to achieve stability; the other uses aluminum alloy ballast, with the front and rear columns combined with a base beam to form a single unit, further counterweighted by cement blocks.

[0003] Patent JP2012104756A, "Standard for Solar Panel Installation," describes a system where each panel is independent and cannot be arranged in combination. Each panel requires multiple pre-positioning steps during installation. For different panel thicknesses, elongated holes are used to control the height, necessitating on-site pre-installation and bolt fixing based on the actual panel dimensions, making construction cumbersome and complex. Pre-positioning is required during installation, and fixing to the roof can damage the roof surface. Patent CN218570147U, "An Angle-Adjustable Photovoltaic Bracket," uses telescopic rods to adjust the height, but customers need to measure the extension of each leg to ensure accuracy when specifying an angle, resulting in parallel photovoltaic solar panels and cumbersome, inefficient construction. Summary of the Invention

[0052] The bottom beam 1 is a rectangular frame. One set of opposite sides of the frame is set as a slide rail 11, and the other set of opposite sides of the frame is set as a support frame 12. The two ends of the two slide rails 11 are respectively fixed to the two ends of the two support frames 12.

[0053] Elevated rubber block 2 is located below the bottom beam 1 and is used to place between the bottom beam 1 and the ground;

[0054] Two front support columns 3 are connected to the front ends of two slide rails 11 respectively. The lower ends of the two front support columns 3 are fixed on the two slide rails 11 respectively. The upper ends of the two front support columns 3 are used to support the front of the photovoltaic panel 6. The bottom of the front support column 3 is provided with multiple fixing holes to realize horizontal position adjustment on the slide rails 11.

[0055] Two rear support columns 4 are respectively connected to the rear ends of two slide rails 11. The lower ends of the two rear support columns 4 are respectively fixed on the two slide rails 11, and the upper ends of the two rear support columns 4 are used to support the rear of the photovoltaic panel 6. The rear support column 4 is provided with a replaceable column 43, and the height can be adjusted by adding or removing the replaceable column 43.

[0056] Ballast 5 is placed at the corresponding position of the support frame 12 of the bottom beam 1 to stabilize the bottom beam 1.

[0057] See Figures 3 to 5 The diagram shown is a structural diagram of the front column assembly, the first pressure block, and the front column pressure block support of an adjustable ballast photovoltaic support module according to an embodiment of the present invention. The front column assembly further includes:

[0058] The first pressure block 10 is an L-shaped plate. One side of the L-shape is provided with a first hole 10a for engaging the first fixing bolt 7 and a first fixing surface 10b for fixing the photovoltaic panel 6. The other end of the L-shape is provided with a first buckle 10c. The photovoltaic panels of different specifications can be fixed on the front column pressure block support 31 by means of the first buckle 10c and the first fixing bolt 7.

[0059] The front column support block 31 has a flat bottom. A vertical flat plate extends vertically upwards from one end of the bottom flat plate 31e, forming an L-shaped plate. A middle flat plate extends vertically from the middle of the vertical flat plate. An upper side plate extends vertically upwards from the middle of the middle flat plate, and a lower side plate extends vertically downwards from the middle of the middle side plate. A small flat plate 31h, flush with the bottom flat plate, extends vertically from the bottom of the lower side plate. The bottom flat plate 31e has multiple second holes 31a for engaging the first fixing bolts 7 to fix it to the slide rail 11, thus adjusting the horizontal position of the front column assembly 3 on the slide rail 11. The upper half of the flat plate has a toothed groove 31c on the side facing the bottom plate, which is used to engage with the first buckle 10c of the first pressure block 10; the upper half of the vertical plate, facing away from the bottom plate, forms a groove 31d with the upper side plate and the middle plate near the vertical plate, and a third hole 31f is provided at the bottom of the groove, which is used to engage with the first fixing bolt 7 of the front column to fix the first pressure block 10; the middle plate away from the vertical plate is a placement platform 31b, which is used to place the photovoltaic panel 6 and engages with the first fixing surface 10b of the first pressure block 10 to fix the photovoltaic panel 6.

[0060] The first fixing bolt 7 is used to fix the first pressure block 10 on the front column pressure block support 31 and to fix the front column pressure block support 31 on the slide rail 11.

[0061] The elastic support 8 and the grounding plate 9 are used to achieve the grounding function. The elastic support 8 is located in the slot 31d and is engaged between the bottom of the slot 31d and the first fixing surface 10b of the first pressure block 10. The first fixing surface 10b is provided with further limiting elasticity.

[0062] Specifically, a protrusion 10g is provided at the bottom of the fixing surface 10b of the first pressure block 10. The protrusion 10g, together with the slot of the front column pressure block support 31 near the side 31g of the placement platform 31b, restricts the horizontal movement of the photovoltaic panel.

[0063] The method for fixing photovoltaic panels of different thicknesses using the front column assembly 3 is as follows: The photovoltaic panel is placed on the placement platform 31b. The first buckle 10c of the first pressure block 10, in conjunction with the toothed groove 31c, adjusts the height to accommodate photovoltaic panels of different thicknesses. The first fixing surface 10b is attached to the top surface of the photovoltaic panel. The first fixing bolt 7 locks the first pressure block 10 and the front column pressure block support 31, thus clamping the photovoltaic panel between the placement platform 31b and the first fixing surface 10b. At the installation site, simply pulling the first pressure block 10 slightly to the side and placing the slot downwards or upwards is sufficient to fix photovoltaic panel modules of different thicknesses. This eliminates the need for multiple hole machining operations at the factory or cumbersome on-site pre-assembly, achieving a convenient, quick, and adjustable installation. Furthermore, the grounding function is achieved through the assembly of the grounding plate 9, the first pressure block 10, and the elastic support 8, providing both adjustability and grounding functionality without the need for an additional grounding wire.

[0064] See Figures 6 to 9 The diagram shown is a structural diagram of the rear column assembly, second pressure block, rear column pressure block support, rear column base, and replaceable column of an adjustable ballast photovoltaic support module according to an embodiment of the present invention. The rear column assembly 4 includes:

[0065] The second pressure block 20 is an L-shaped plate. One side of the L-shape is provided with a fourth hole 20a for cooperating with the second fixing bolt 13 and a second fixing surface 20g for fixing the photovoltaic panel. The other end of the L-shape is provided with a second buckle 20c. The photovoltaic panels of different specifications can be fixed on the rear column pressure block support 41 by means of the second buckle 20c and the second fixing bolt 13.

[0066] The rear column base 42 is a rectangular support column with a fifth hole 42a at the bottom end for the second fixing bolt 13, and the top end is connected to the replaceable column 43 or to the rear column pressure block support.

[0067] The replaceable column 43 is a rectangular support column with a positioning rib at the bottom that matches the slot at the top of the rear column base, and the top of the column matches the rear column pressure block support.

[0068] The rear column pressure block support 41 has a main body as a placement platform 41e, which is used to place the photovoltaic panel 6 and cooperates with the second fixing surface 20g of the second pressure block 20 to fix the photovoltaic panel 6.

[0069] One end of the placement platform 41e extends vertically upward into a vertical plate. The vertical plate is provided with a toothed groove 41c. The toothed groove 41c is used to cooperate with the second buckle 20c of the second pressure block 20. A slot 41d is also provided between the placement platform 41e and the toothed groove 41c. A sixth hole 41f is provided at the bottom of the slot for cooperating with the second fixing bolt 13 to fix the second pressure block 20.

[0070] The bottom of the placement platform 41e of the rear column pressure block support 41 is provided with two positioning ribs 41a for engaging with the rear column base 42 or the replaceable column 43. One of the positioning ribs is also provided with two holes 41b for further fixing with the second fixing bolt 13. The bottom of the rear column base 42 is provided with holes 42a for engaging with the second fixing bolt 13 to fix it on the slide rail 11. The top of the rear column base 42 is provided with a positioning groove 42b.

[0071] The replaceable column 43 has two positioning ribs 43a at its bottom and a positioning slot 43b at its top. The second fixing bolt 13 is used to fix the second pressure block 20 to the rear column pressure block support 41 and to fix the rear column base 42 to the slide rail 11.

[0072] A seventh hole is provided on one of the positioning ribs of the rear column base, the side of the replaceable column, and the rear column pressure block support. The seventh holes between the rear column base and the replaceable column, the rear column base and the rear column pressure block support, and the replaceable column and the rear column pressure block support are corresponding to each other and are used to further fix and connect with the third fixing bolt 14.

[0073] The elastic support 8 and the grounding plate 9 are used to achieve the grounding function. The elastic support 8 is located in the slot 41d and is locked between the bottom of the slot 41d and the second fixing surface 20b of the second pressure block 20. The second fixing surface 20b is provided with a limiting plate 20g that further restricts the elastic support 8. The elastic support 8 is provided with a hole for the second fixing bolt 13 to pass through.

[0074] The method for fixing photovoltaic panels of different thicknesses using the rear column assembly 3 is as follows: The photovoltaic panel is placed on the placement platform 41e. The second buckle 20c of the second pressure block 20, in conjunction with the toothed groove 41c, adjusts the height to accommodate photovoltaic panels of different thicknesses. The second fixing surface 20b is attached to the top surface of the photovoltaic panel. The second fixing bolt 13 locks the second pressure block 20 and the rear column pressure block support 41, thus clamping the photovoltaic panel between the placement platform 41e and the second fixing surface 20b. At the installation site, simply pulling the second pressure block 20 slightly to the side and placing the slot downwards or upwards is sufficient to fix photovoltaic panel modules of different thicknesses. This eliminates the need for multiple hole machining operations at the factory or cumbersome on-site pre-assembly, achieving a convenient, quick, and adjustable installation. Furthermore, the grounding function is achieved through the assembly of the grounding plate 9, the second pressure block 20, and the elastic support 8, providing both adjustability and grounding functionality without the need for an additional grounding wire.

[0075] This embodiment discloses an adjustable ballast photovoltaic support module. The rear column assembly adopts a sequential connection of "rear column base - replaceable column - rear column pressure block bracket". The height of the rear column assembly can be adjusted by increasing or decreasing the number of replaceable columns. The connection method between the rear column base 42 and the rear column pressure block bracket 41 is as follows: the positioning slot 42b of the rear column base 42 is engaged with the positioning rib 42a of the rear column pressure block bracket 41. The connection method between the rear column base 42 and the replaceable column 43 is as follows: the positioning slot 42b of the rear column base 42 is engaged with the positioning rib 43a of the replaceable column 43. The connection method between two replaceable columns 43 is as follows: the positioning slot 43b of one replaceable column 43 is engaged with the positioning rib 43a of the other replaceable column. The connection method between the replaceable upright and the rear upright pressure block bracket 41 is as follows: the positioning slot 43b of the replaceable upright is connected to the positioning rib 42a of the rear upright pressure block bracket 41. In order to accommodate rear upright assemblies of different heights, the front upright assembly needs to be fixed at different positions on the slide rail, which is achieved by selecting different hole positions 31a on the bottom of the plane 31e.

[0076] See Figure 10 The diagram shows the pre-assembled structure of an adjustable ballast photovoltaic support module according to an embodiment of the present invention. It includes a base beam 1, a raised rubber block 2, a front column assembly 3, and a rear column assembly 4. Both the front column assembly 3 and the rear column assembly 4 are fixed to a slide rail by fixing bolts 7. The rear column assembly is laid flat on the slide rail to reduce its size and facilitate transportation. Both the front column assembly 3 and the rear column assembly 4 of the pre-assembled module are equipped with elastic support members 8 and grounding plates 9. The elastic support member 8 supports the grounding plate 9, ensuring that the grounding plate 9 is tightly attached to the first pressure block 10 or the second pressure block 20, thus providing a fixing function. This eliminates the need to manually lift the grounding plate and the first pressure block during later installation of the pre-assembled module, facilitating installation. The elastic support member, placed in a slot, also restricts the movement of the first or second pressure block, solving the sway problem.

[0077] See Figure 11 The diagram shown is a schematic of a single-row assembly application of an adjustable ballast photovoltaic support system according to an embodiment of the present invention. The bottom beams of the front and rear modules are provided with the sides of the support frame and are fixed together by cement ballast.

[0078] See Figure 12 The diagram shown illustrates two single-row assembly methods for an adjustable ballast photovoltaic support system according to an embodiment of the present invention. Figure 12 (a) is a single-slope assembly. Figure 12 (b) Back-to-back assembly; when assembling on a single slope, the front and back of the same cement ballast are respectively the rear column assembly of the front module and the front column assembly of the rear module; when assembling back-to-back, the front and back of the same cement ballast are either the front column assembly of the front and rear modules or the rear column assembly of the front and rear modules.

[0079] See Figure 13 The diagram shown is a schematic diagram of the multi-row assembly application of an adjustable ballast photovoltaic support system according to an embodiment of the present invention. Multiple single rows are assembled together, and the adjacent edges of adjacent photovoltaic panels in the same row can be fixed together to further enhance stability.

[0080] The modular design of this invention is flexible. During installation, only the frontmost part of the arrangement needs to be positioned once, and subsequent installation can be quickly achieved through connectors, resulting in efficient positioning and quick installation.
