Description

Technical Field

[0001] This application relates to the field of photovoltaic accessory technology, and more specifically, to a photovoltaic bracket and a photovoltaic system. Background Technology

[0002] Solar energy is one of the clean, reliable, and safe energy sources of the future. The most common and currently best way to utilize solar energy is through photovoltaic (PV) conversion. A solar photovoltaic module is a device that generates electricity under sunlight. PV modules can be connected together to produce even higher power output. These modules can be installed on rooftops or building exteriors to ensure adequate sunlight exposure.

[0003] Since photovoltaic (PV) modules are typically used outdoors, they generally require PV support arms for support and fixation during use. In related technologies, PV support arms usually adopt a fixed structure. These types of support arms can generally only accommodate PV modules of a specific size and lack sufficient adjustability. If it is necessary to support PV modules of different sizes, different PV support arms are usually required, which increases the subsequent installation and maintenance costs. Utility Model Content

[0004] One or more embodiments of this application are intended to solve or at least partially alleviate the problem of poor adjustability of existing photovoltaic brackets.

Therefore, by being clamped in two directions (the length of the fixed rail and the thickness of the PV module), the PV module achieves better fixation and higher stability. Furthermore, since each clamping component can slide on the fixed rail and form an adjustable clamping space between adjacent clamping components, it can ensure that adjacent clamping components can clamp and fix PV modules of different sizes (different dimensions of the PV module along the length of the fixed rail), providing a degree of adjustability and improving the versatility of this PV mounting bracket for PV modules of different sizes.

Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0038] One or more embodiments of this application disclose a photovoltaic bracket, such as Figure 1-2 and Figure 5-7 As shown, the photovoltaic bracket includes a fixing unit 7, which includes a fixing rail 1 and multiple clamping components 2. Each clamping component 2 is slidably connected to the fixing rail 1. An adjustable clamping space 9 is formed between two adjacent clamping components 2, and each clamping component 2 is also used to clamp the end of the photovoltaic component 3 in the thickness direction.

[0039] In at least one embodiment, when the photovoltaic bracket supports the photovoltaic module 3, the photovoltaic module 3 can be placed between two adjacent clamping components 2 on the fixed rail 1. The two adjacent clamping components 2 can clamp the photovoltaic module 3 between them in the length direction of the fixed rail 1, and each clamping component 2 can also clamp the end of the photovoltaic module 3 in the thickness direction of the photovoltaic module 3. Thus, the photovoltaic module 3 is clamped in two directions (the length direction of the fixed rail 1 and the thickness direction of the photovoltaic module 3), resulting in better fixation and higher stability. In addition, since each clamping component 2 can slide on the fixed rail 1 and can form an adjustable clamping space 9 between two adjacent clamping components 2, it can be ensured that the two adjacent clamping components 2 can clamp and fix photovoltaic modules 3 of different sizes (different sizes of photovoltaic modules 3 in the length direction of the fixed rail 1), which has a certain degree of adjustability and can improve the versatility of the photovoltaic bracket for photovoltaic modules 3 of different sizes.

[0040] It should be noted that, along the length of the fixed rail 1, since two adjacent clamping components 2 clamp the photovoltaic module 3 between them, meaning that the photovoltaic module 3 has clamping components 2 at both ends along the length of the fixed rail 1, the photovoltaic support structure carrying the photovoltaic module 3 can be angled in actual use. For example, the photovoltaic support structure can be rotated around the Y-axis by a certain angle to tilt the photovoltaic module 3. After the photovoltaic support structure is rotated around the Y-axis to tilt the photovoltaic module 3, one of the two clamping components 2 will be located at the bottom end in the tilting direction of the photovoltaic module 3, ensuring effective support for the tilted photovoltaic module 3.

[0041] It should be noted that, as Figure 1 as well as Figure 5 As shown, there can be two clamping components 2 on a fixed rail 1. In this case, the aforementioned "two adjacent clamping components 2 among the multiple clamping components 2" refers to these two clamping components 2.

[0042] In at least one embodiment, such as Figure 8 As shown, there can be more than two clamping components 2 on a fixed rail 1, for example, Figure 8 As shown, four clamping components 2 are slidably connected on a fixed rail 1. In this case, the aforementioned "two adjacent clamping components 2 among the multiple clamping components 2" can refer to any two adjacent clamping components 2 among these four clamping components 2. The aforementioned clamping space 9 can be formed between any two adjacent clamping components 2, that is, any two adjacent clamping components 2 can clamp the photovoltaic module 3.

[0043] In some embodiments, such as Figure 2-3 As shown, the clamping assembly 2 includes a sliding seat 21 and a clamping block 22. The sliding seat 21 is slidably connected to the fixed rail 1. The clamping block 22 includes a first clamping block 221 and a second clamping block 222 connected at an angle along the length direction of the fixed rail 1. The clamping space 9 is formed between the first clamping blocks 221 of two adjacent clamping assemblies 2. The second clamping block 222 of each clamping assembly 2 and the sliding seat 21 are used to clamp the end of the photovoltaic module 3 in the thickness direction of the photovoltaic module 3.

[0044] In at least one embodiment, in the fixing unit 7, the clamping component 2 is specifically slidably connected to the fixing rail 1 via the sliding seat 21. On the fixing rail 1, the aforementioned "adjustable clamping space 9 formed between two adjacent clamping components 2" specifically refers to the clamping space 9 formed between the first clamping blocks 221 of two adjacent clamping components 2. The two clamping blocks 22 of two adjacent clamping components 2 cooperate to clamp the photovoltaic module 3 between them in the length direction of the fixing rail 1. The second clamping block 222 of each clamping block 22 cooperates with the corresponding sliding seat 21 to clamp the photovoltaic module 3 between them in the thickness direction, thereby realizing the clamping of the photovoltaic module 3 in two directions.

[0045] In some embodiments, such as Figure 2-3 and Figure 7 As shown, the sliding seat 21 is provided with a docking part 2121, and the first clamping block 221 is detachably connected to the docking part 2121 along the thickness direction of the photovoltaic module 3.

[0046] In at least one embodiment, such as Figure 2-3 As shown, the clamping block 22 can be detachably connected to the docking portion 2121 of the sliding seat 21. When carrying the photovoltaic module 3, the clamping block 22 can be removed from the sliding seat 21 first, and then both ends of the photovoltaic module 3 can be placed on the sliding seats 21 of two adjacent clamping components 2. Then, the first clamping block 221 can be moved along the thickness direction of the photovoltaic module 3 until it connects with the docking portion 2121, thereby achieving that the end of the photovoltaic module 3 is clamped between the second clamping block 222 and the sliding seat 21 in the thickness direction. In the length direction of the fixed rail 1, both ends of the photovoltaic module 3 can abut against the corresponding first clamping block 221, and in the thickness direction of the photovoltaic module 3, the photovoltaic module 3 is also clamped by the second clamping block 222 and the sliding seat 21.

[0047] In at least one embodiment, such as Figure 2-3 As shown, the sliding seat 21 is provided with a docking part 2121 on the side facing the second clamping block 222. The first clamping block 221 is used to dock with the docking part 2121 along the thickness direction of the photovoltaic module 3. During the process of the first clamping block 221 gradually docking with the docking part 2121, the second clamping block 222 can clamp the photovoltaic module 3 in the thickness direction, which is time-saving and efficient.

[0048] In some embodiments, such as Figure 2-3 As shown, the clamping assembly 2 further includes a first locking structure 23, which includes a first fastener 231. The first fastener 231 is used to be inserted into the second clamping block 222 and the sliding seat 21 in sequence.

[0049] In at least one embodiment, such as Figure 2-3As shown, after the first clamping block 221 is connected to the docking part 2121, the first fastener 231 can be inserted into the second clamping block 222 and the sliding seat 21 in sequence to fix the second clamping block 222 and the sliding seat 21 relative to each other, thereby achieving relative fixation of the clamping block 22 and the sliding seat 21, and making disassembly and assembly convenient.

[0050] In at least one embodiment, such as Figure 2-3 As shown, the first fastener 231 can also abut against the end of the photovoltaic module 3. In this case, the aforementioned "adjustable clamping space 9 is formed between two adjacent clamping components 2" specifically refers to the clamping space 9 formed between the first fasteners 231 of two adjacent clamping components 2. That is, in the length direction of the fixed rail 1, the photovoltaic module 3 can be clamped by the first fasteners 231 on both sides.

[0051] In at least one embodiment, such as Figure 2-3 As shown, the sliding seat 21 includes a sliding main body 211 and a sliding support 212. The sliding main body 211 is slidably connected to the fixed rail 1, and the sliding support 212 is disposed on the sliding main body 211. The mating part 2121 is disposed at the sliding support 212, and the mating part 2121 can be a slot. The first clamping block 221 of the clamping block is used to be inserted into the slot. Thus, when installing the clamping block 22, at least a portion of the first clamping block 221 of the clamping block 22 is inserted into the slot. After the clamping block 22 is inserted, the second clamping block 222 of the clamping block 22 can be connected and fixed to the sliding main body 211 using the first fastener 231.

[0052] The angle between the first clamping block 221 and the second clamping block 222 can be 90°. This ensures the stability of the clamping block 22 structure and also ensures that when the first clamping block 221 is inserted into the slot along the Z-axis, the side of the second clamping block 222 facing the photovoltaic module 3 is parallel to the surface of the photovoltaic module 3, thus ensuring a large contact area when the second clamping block 222 clamps the photovoltaic module 3.

[0053] In some embodiments, such as Figure 2 As shown, the clamping assembly 2 also includes a movable locking structure 4, which is used to lock the sliding seat 21 at a set position on the fixed rail 1.

[0054] In at least one embodiment, when the sliding seat 21 of the clamping component 2 on the fixed rail 1 slides to the set position, the sliding seat 21 can be locked in that position by the movable locking structure 4, so as to ensure that the adjusted clamping space 9 between two adjacent clamping components 2 remains stable and to prevent the clamping component 2 from moving accidentally.

[0055] In some embodiments, such as Figure 2 and Figure 4 As shown, at least one side of the fixed rail 1 is provided with a groove 11. The sliding seat 21 includes a sliding main seat 211 and a sliding support 212, and may also include a slider 214. The slider 214 is slidably connected in the groove 11, and the sliding seat 21 is connected to the slider 214. Thus, the sliding seat 21 can slide along the length direction of the fixed rail 1 through the slider 214, realizing the smoothness of the sliding of the clamping component 2 and having a certain degree of stability.

[0056] In some embodiments, such as Figure 2 and Figure 4 As shown, the fixed rail 1 is provided with a plurality of first positioning holes 111 in sequence along its length direction, the movable locking structure 4 includes a second fastener 41, and the sliding seat 21 is provided with a second positioning hole 2141. The second fastener 41 is used to be inserted into the second positioning hole 2141 and any one of the first positioning holes 111 in sequence.

[0057] In at least one embodiment, when the sliding seat 21 of the clamping component 2 on the fixed rail 1 slides to the set position, the second fastener 41 can be sequentially inserted into the second positioning hole 2141 and any one of the first positioning holes 111 on the fixed rail, thereby fixing the sliding seat 21 and the clamping component 2 at this position, ensuring that the adjusted clamping space 9 between two adjacent clamping components 2 remains stable, and preventing the clamping component 2 from moving accidentally.

[0058] In at least one embodiment, such as Figure 2 and Figure 4 As shown, multiple first positioning holes 111 can be sequentially arranged on the inner wall of the slide groove 11, and second positioning holes 2141 can be arranged on the slider 214.

[0059] In at least one embodiment, the second fastener 41 may be a bolt (denoted as the second bolt), and at least one of the first positioning hole 111 and the second positioning hole 2141 is a threaded hole. Thus, the clamping assembly 2 is locked in the set position in the length direction of the fixed rail 1 by the connection between the second bolt and the threaded hole.

[0060] In some embodiments, such as Figure 2-4 As shown, the fixed rail 1 is provided with the sliding groove 11 on both sides, and the sliding seat 21 (specifically the sliding body seat 211) is provided with the slider 214 on both sides. The sliding seat 21 partially surrounds the fixed rail 1, and the opposite sides of the sliding seat 21 are slidably connected to the corresponding sliding groove 11 by the corresponding slider 214.

[0061] In at least one embodiment, the fixed rail 1 has grooves 11 on both sides, and the sliding seat 21, which is semi-enclosed by the fixed rail 1, is slidably connected to the corresponding grooves 11 on both sides by corresponding sliders 214, so that the sliding seat 21 is balanced by forces on both sides when sliding along the fixed rail 1, making the sliding more stable. In addition, the sliding seat 21 (specifically the sliding body seat 211) and the fixed rail 1 can be spaced apart, with a first gap space 213 between them, which can prevent the sliding seat 21 from rubbing against the fixed rail 1 when sliding. In addition, the aforementioned first fastener 231 can be a bolt (denoted as the first bolt). In this case, the first locking structure can also include a first nut 232. After the first fastener 231 is inserted into the second clamping block 222 and the sliding seat 21 in sequence, the first nut 232 can be locked onto the first fastener 231 at the first gap space 213, ensuring the stability of the first fastener 231 after connection and preventing the first fastener 231 from falling off.

[0062] In cases where the size of the first gap space 213 is small, a wrench can be used to place the first nut 232 into the first gap space 213, and then the first fastener 231 can be sequentially inserted into the second clamping block 222, the sliding seat 21, and the first nut 232. In at least one embodiment, such as Figure 4 As shown, the first locking structure may also include a first washer 233, which is located between the first nut 232 and the sliding seat 21. By setting the first washer 233, the first fastener 231 can be prevented from loosening to a certain extent.

[0063] In some embodiments, such as Figure 2 As shown, the slide groove 11 extends through the fixed rail 1 along its length.

[0064] In at least one embodiment, the slide groove 11 extends through the fixed rail 1 along the length direction of the fixed rail 1, which allows the slider 214 to be moved out from the end of the slide groove 11, thereby enabling the clamping assembly 2 to be disassembled from the fixed rail 1.

[0065] In some embodiments, such as Figure 2-3 and Figure 6 The fixing unit 7 further includes an end cap seat 5, and the fixing rail 1 is used to be placed between two end cap seats 5, and the end of the fixing rail 1 is detachably connected to the corresponding end cap seat 5.

[0066] In some embodiments, after the fixed rail 1 is placed between the two end cap seats 5, the end of the fixed rail 1 can be detachably connected to the end cap seat 5. In this way, on the one hand, the end cap seat 5 can block the end of the aforementioned slide groove 11, preventing the sliding seat 21 from sliding out of the slide groove; on the other hand, the end cap seat 5 can be used as the mounting seat of the fixed unit 7 for installation and fixation with the external structure, for example, by fixing it to the support frame 8 through the end cap seat 5; when disassembling the fixed rail 1, it is only necessary to detach the end of the fixed rail 1 from the end cap seat 5, which is quick and convenient.

[0067] In some embodiments, such as Figure 2-3 and Figure 6 The fixing unit 7 further includes a first docking member 61 and a second docking member 62. The end cap seat 5 is provided with a third connecting hole 51. The fixing rail 1 is used to be placed between the two end cap seats 5. The two ends of the fixing rail 1 are respectively embedded with the second docking member 62. The first docking member 61 is used to be detachably connected to the second docking member 62 through the third connecting hole 51.

[0068] In at least one embodiment, the fixed rail 1 can be disposed between the two end cap seats 5, and then connected to the second connecting piece 62 inside the fixed rail 1 via the first connecting piece 61 through the third connecting hole 51, thereby achieving a fixed connection between the two end cap seats 5 and the fixed rail 1. At this time, the end cap seats 5 are equivalent to closing the opening at the end of the slide groove 11, which can ensure that the slider 214 will not slide out from the opening at both ends of the slide groove 11. For example, for convenient transportation, the first connecting piece 61 and the second connecting piece 62 can be separated, and the fixed rail 1 can be removed from between the two end cap seats 5. Then, the slider 214 can be removed from the opening at the end of the slide groove 11 to remove the clamping assembly 2, making disassembly and assembly convenient.

[0069] In some embodiments, such as Figure 1 and Figure 5 The photovoltaic bracket further includes a support frame 8, and a plurality of fixing units 7 are sequentially distributed on the support frame 8 along the length direction of the fixing rail 1; or / and; the support frame 8 includes a plurality of second beams 82 sequentially distributed along a set direction, the length direction of the second beams 82 being parallel to the length direction of the fixing rail 1, and a plurality of fixing units 7 are sequentially provided on each second beam 82 along the set direction, wherein the set direction is perpendicular to the length direction of the fixing rail 1.

[0070] In at least one embodiment, the fixing unit 7 is mounted on the support frame 8. In a single fixing unit 7, it can be fixedly connected to the support frame 8 via an end cap 5, while the fixing rail 1 can be indirectly fixed to the support frame 8 by connecting to the end cap 5, facilitating the disassembly of the fixing rail 1 and its clamping assembly 2. Figure 1As shown, multiple fixing units 7 are sequentially distributed on the support frame 8 along the length direction (X-axis direction) of the fixing rail 1. In this way, multiple photovoltaic modules 3 can be clamped and fixed along the length direction of the support frame 8, thereby improving the functionality of the photovoltaic bracket.

[0071] In at least one embodiment, the support frame 8 includes a plurality of second beams 82 sequentially distributed along the predetermined direction (Y-axis direction in the figure), each second beam 82 being provided with a fixing unit 7, wherein the predetermined direction is perpendicular to the length direction of the fixing rail 1. Thus, the two ends of the photovoltaic module 3 in the Y-direction can be clamped and fixed by the fixing units 7 on the corresponding second beams 82, ultimately achieving that all four corners of a photovoltaic module 3 can be clamped, resulting in better stability of the photovoltaic module 3. Furthermore, as... Figure 1 As shown, each of the second beams 82 is provided with a plurality of fixing units 7 in sequence along a set direction. In this way, the two ends of the photovoltaic module 3 in the Y direction can be clamped by the corresponding fixing units 7 on their respective adjacent second beams 82, ensuring the universality of photovoltaic modules 3 with different Y-direction dimensions.

[0072] In at least one embodiment, such as Figure 1 and Figure 5 The support frame 8 further includes first beams 81, with multiple first beams 81 distributed sequentially along the length of the fixed rail 1. Each first beam 81 extends along a predetermined direction, and multiple second beams 82 are sequentially disposed on the first beams 81 along the predetermined direction, with the second beams 82 extending along the length of the fixed rail 1. This distribution of the first beams 81 and the second beams 82 ensures that the support frame 8 has high structural strength, guaranteeing effective support for the fixed unit 7 and the photovoltaic module 3.

[0073] In addition, one or more embodiments of this application provide a photovoltaic system, see [link to relevant documentation]. Figure 1 The photovoltaic system includes photovoltaic modules and photovoltaic brackets as described above.

[0074] In at least one embodiment, the photovoltaic system has at least all the technical effects of the photovoltaic bracket, which will not be described in detail here.

[0075] In some embodiments, such as Figure 2-3 as well as Figure 7 As shown, the photovoltaic module 3 is provided with a third positioning hole 321, the clamping block 22 of the photovoltaic bracket is provided with a fourth positioning hole 2221, and the clamping component 2 also includes a third fastener 26, which is used to be inserted into the fourth positioning hole 2221 and the third positioning hole 321 in sequence.

[0076] In at least one embodiment, after the clamping component 2 clamps and fixes the photovoltaic module 3, the third fastener 26 can be inserted into the fourth positioning hole 2221 and the third positioning hole 321 in sequence to lock the photovoltaic module 3, thereby further fixing the photovoltaic module 3 and making the photovoltaic module 3 more stable.

[0077] In some embodiments, such as Figure 1 and Figure 5-7 The photovoltaic module 3 includes a photovoltaic module body 31 and a frame 32 connected thereto. The third positioning hole 321 is disposed at the frame 32, and the fourth positioning hole 2221 is disposed on the second clamping block 222.

[0078] In at least one embodiment, after the photovoltaic module 3 is clamped and fixed, a third fastener 26 can be sequentially inserted into the fourth positioning hole 2221 of the second clamping block 222 and the third positioning hole 321 of the frame 32, thereby connecting and locking the second clamping block 222 and the frame 32 through the third fastener 26, thereby further improving the stability of the photovoltaic module 3 in positioning and fixing. The third fastener 26 can be a bolt (denoted as the third bolt).

[0079] In some embodiments, such as Figure 7 As shown, in the thickness direction of the photovoltaic module 3, a second gap space 33 is provided between the frame 32 and the photovoltaic module body 31; the clamping component 2 also includes a second nut 27, which is located at the second gap space 33 and threadedly connected to the third fastener 26.

[0080] In at least one embodiment, the clamping assembly 2 may further include a second nut 27. After the third bolt, which serves as the third fastener 26, is sequentially inserted into the fourth positioning hole 2221 and the third positioning hole 321, the second nut 27 can be locked onto the third bolt from the second gap space 33 to ensure the stability of the third bolt connection. The clamping assembly 2 may also include a second washer 28, which is sleeved on the third bolt and located between the second nut 27 and the third positioning hole 321. The second washer 28 helps to prevent the second nut 27 from loosening to a certain extent.

[0081] The frame 32 has multiple third positioning holes 321 at one end of the X-axis direction along the set direction (Y-axis direction), and multiple third positioning holes 321 at the other end of the X-axis direction as well, ensuring that the third fasteners 26 of the fixing units 7 at both ends of the photovoltaic module 3 in the lateral (Y-axis direction) direction can be sequentially connected to the fourth positioning hole 2221 and the corresponding third positioning hole 321, so as to further lock the photovoltaic module 3 and achieve applicability to photovoltaic modules 3 with different lateral dimensions.
