Description

Technical Field

[0001] The utility model relates to the technical field of solar photovoltaic panel accessories, in particular to a solar photovoltaic panel fixing structure. Background Art

[0002] Solar photovoltaic panels, also known as solar electric panels, are devices that use the photoelectric effect, or photochemical effect, to directly or indirectly convert sunlight into electrical energy. They typically consist of a base plate, solar cells, a translucent cover, and metal edge banding. Because the power generation capacity of a single solar photovoltaic panel is limited, multiple panels are often used to improve efficiency and output. When installing a solar photovoltaic panel, a stainless steel or aluminum alloy bracket is typically used to construct the base in a relatively open area. Fasteners are then used to press down the metal edge banding of the solar photovoltaic panel, and bolts are then used to secure the fasteners to the bracket.

[0003] In the prior art, fasteners are typically made of aluminum alloy and are divided into single-buckle and double-buckle fasteners. Single-buckle fasteners can only hold down one solar photovoltaic panel, while double-buckle fasteners can simultaneously hold down two adjacent solar photovoltaic panels. To reduce installation gaps and improve space utilization, single-buckle fasteners are typically used on the outer edges of the outermost solar photovoltaic panels, while double-buckle fasteners are used between the inner solar panels. However, when using double-buckle fasteners, only one side of one solar photovoltaic panel is fixed, resulting in an unstable fixation. Someone needs to hold the panel in place, while the other panel remains unfixed, requiring two more people to hold the panel in place. Therefore, at least three people are required to coordinate and complete the installation of the solar panels, which is time-consuming, labor-intensive, and inefficient. Utility Model Content

[0030] Example 1:

[0031] See also Figure 1-5 The present invention describes the above technical solution in detail through the following embodiments:

[0032] A solar photovoltaic panel fixing structure, comprising:

[0033] The mounting bracket 2 includes a column 21 , a longitudinal beam 22 is fixedly installed above the column 21 by bolts, a cross beam 24 is fixedly installed between the longitudinal beams 22 by bolts, and a photovoltaic panel 1 is installed on the cross beam 24 through a first fastener 3 and a second fastener 4.

[0034] The columns 21 are used to support the longitudinal beams 22 . A diagonal bracing beam 23 is fixedly installed between the longitudinal beams 22 and the columns 21 by bolts. The diagonal bracing beam 23 is used to provide additional support.

[0035] The photovoltaic panel 1 adopts a well-known solar photovoltaic panel.

[0036] A mounting slot 25 is provided on the top surface of the crossbeam 24 , and the first fastener 3 and the second fastener 4 are slidably connected to the mounting slot 25 .

[0037] The first fastener 3 and the second fastener 4 are slidably connected to the installation slide groove 25 through bolts, and the installation slide groove 25 can facilitate the first fastener 3 and the second fastener 4 to adjust their positions.

[0038] The first fastener 3 is located outside the outermost photovoltaic panel 1 . The first fastener 3 includes a pressing plate 31 . The bottom surface of the pressing plate 31 abuts against the outer top surface of the outermost photovoltaic panel 1 .

[0039] The pressing plate 31 is used to fix the outer side of the outermost photovoltaic panel 1 .

[0040] A connecting plate 32 is provided below the tail end of the pressing plate 31 , a fixing plate 33 is provided on the outside of the bottom of the connecting plate 32 , a supporting foot 34 is provided below the tail end of the fixing plate 33 , and the bottom surface of the supporting foot 34 abuts against the top surface of the beam 24 .

[0041] The first fastener 3 is integrally formed of aluminum alloy. The bolts penetrate the fixing plate 33 and are then inserted into the mounting slots 25. The tension of the bolts forces the support legs 34 to press against the top surface of the crossbeam 24, while also ensuring that the bottom surface of the pressure plate 31 presses against the outer top surface of the outermost photovoltaic panel 1.

[0042] The second fastener 4 is located between two adjacent photovoltaic panels 1. The second fastener 4 includes a U-shaped plate 41. A fixed pressure plate 42 is provided on the top right side of the U-shaped plate 41. The fixed pressure plate 42 is used to fix the left side of the photovoltaic panel 1 on the right side. A rotating plate is provided on the top left side of the U-shaped plate 41. A limiting device is provided under the tail of the rotating plate. The limiting device is used to limit the rotation of the rotating plate.

[0043] The U-shaped plate 41 and the fixed pressing plate 42 are integrally formed of aluminum alloy. The right end of the fixed pressing plate 42 exceeds the right side of the U-shaped plate 41.

[0044] An elastic member 49 is provided below the U-shaped plate 41 , and the bottom surface of the elastic member 49 abuts against the top surface of the crossbeam 24 .

[0045] The elastic member 49 can be a rubber pad. A bolt passes downward through the middle of the U-shaped plate 41 and the elastic member 49, then snaps into the mounting slot 25. The tension of the bolt forces the bottom surface of the elastic member 49 against the top surface of the crossbeam 24, while also ensuring that the bottom surface of the fixed pressure plate 42 abuts against the top surface of the left side of the photovoltaic panel 1 on the right side. The elastic member 49 provides support for the U-shaped plate 41, preventing it from tilting to the left.

[0046] The rotating plate includes a rotating pressing plate 43 , which is rotatably connected to the U-shaped plate 41 . The head of the rotating pressing plate 43 extends beyond the left side of the U-shaped plate 41 , and a lower pressing block 44 is provided at the tail end of the rotating pressing plate 43 .

[0047] The rotating pressing plate 43 and the lower pressing block 44 are integrally formed of aluminum alloy. Applying a downward force to the lower pressing block 44 can drive the rotating pressing plate 43 to rotate upward, and applying an upward force to the lower pressing block 44 can drive the rotating pressing plate 43 to rotate downward and press the right top surface of the photovoltaic panel 1 on the left.

[0048] The limiting device includes two symmetrically arranged sliding blocks 45 , and an extrusion bevel 46 is provided on opposite sides of the sliding blocks 45 . The top surface of the sliding block 45 abuts against the bottom surface of the pressing block 44 .

[0049] When the sliding blocks 45 approach each other, the pressing bevel 46 contacts the edge of the lower pressing block 44, exerting an upward force on the lower pressing block 44, thereby driving the lower pressing block 44 to rotate upward and causing the rotating pressure plate 43 to rotate downward. When the top surface of the sliding block 45 abuts the bottom surface of the lower pressing block 44, it can restrict the downward rotation of the lower pressing block 44, thereby restricting the upward rotation of the rotating pressure plate 43, thereby maintaining pressure on the right top surface of the photovoltaic panel 1 on the left.

[0050] The bottom of the sliding block 45 is slidably connected to the U-shaped plate 41 through a sliding groove 48 , and the two sliding blocks 45 are connected by an adjusting bolt 47 .

[0051] The slide groove 48 prevents the sliding block 45 from sliding to the right. The adjusting bolt 47 is threadedly connected to the sliding block 45 at the rear end of the adjusting bolt 47 and is also slidably connected to the sliding block 45 near the head of the adjusting bolt 47. By rotating the adjusting bolt 47, the two sliding blocks 45 can be driven to slide relative to each other, thereby controlling the distance between the two sliding blocks 45. When the two sliding blocks 45 abut against each other, the top surface of the sliding block 45 abuts the bottom surface of the lower pressing block 44.

[0052] When using this device in this embodiment, the operator first places the first photovoltaic panel 1 on the crossbeam 24. Bolts are inserted through the fixing plate 33 and then snapped into the mounting slots 25. The tension of the bolts is then used to force the support legs 34 against the top surface of the crossbeam 24, while simultaneously ensuring that the bottom surface of the pressure plate 31 abuts against the top surface of the right photovoltaic panel 1. This secures the right side of the first photovoltaic panel 1.

[0053] Then, place the second fastener 4 on the left side of the first photovoltaic panel 1. The bolt goes through the middle of the U-shaped plate 41 and the middle of the elastic member 49 and then snaps into the mounting slot 25. Using the tension of the bolt, the bottom surface of the elastic member 49 abuts against the top surface of the crossbeam 24. At the same time, the bottom surface of the fixed pressure plate 42 abuts against the top surface of the left side of the right photovoltaic panel 1. This secures the left side of the first photovoltaic panel 1.

[0054] Place the second photovoltaic panel 1 on the crossbeam 24 and slide it to the right, applying downward pressure to the lower pressing block 44, driving the rotating pressing plate 43 to rotate upward until the right side of the second photovoltaic panel 1 abuts against the outer side of the left side of the U-shaped plate 41. Release the pressure on the lower pressing block 44.

[0055] The adjusting bolt 47 is rotated to drive the two sliding blocks 45 toward each other. At this time, the extruded bevel 46 contacts the edge of the lower pressing block 44, which can apply an upward force to the lower pressing block 44, thereby driving the lower pressing block 44 to rotate upward and causing the rotating pressure plate 43 to rotate downward.

[0056] When the two sliding blocks 45 abut against each other, the top surface of the sliding block 45 abuts the bottom surface of the lower pressing block 44. The rotating pressing plate 43 now presses against the right top surface of the left photovoltaic panel 1. Simultaneously, the sliding block 45 restricts the downward rotation of the lower pressing block 44, thereby restricting the upward rotation of the rotating pressing plate 43, thereby maintaining pressure on the right top surface of the left photovoltaic panel 1. This secures the right side of the second photovoltaic panel 1.

[0057] Then place a new second fastener 4 on the left side of the second photovoltaic panel 1 for fixing.

[0058] Repeat the above steps, and finally fix the left side of the leftmost photovoltaic panel 1 with the first fastener 3 to achieve the fixation of all photovoltaic panels 1.

The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
