Photovoltaic brackets and photovoltaic systems

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on April 2, 2024, with application number 2024103981012 and invention name “Photovoltaic Bracket and Photovoltaic System”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of photovoltaic installation technology, and in particular to photovoltaic brackets and photovoltaic systems. Background Art

[0003] With the development of the photovoltaic industry, photovoltaic systems are becoming increasingly diverse. Small, distributed photovoltaic systems installed on building balconies or outdoor railings are gaining popularity. These systems use photovoltaic modules to absorb sunlight and convert it into direct current (DC). Installation of a photovoltaic system primarily involves installing the modules, mounting the photovoltaic brackets on the balcony wall or railing, and then mounting the modules on the brackets.

[0004] Currently, when attaching a photovoltaic mount to a balcony wall, holes must be drilled in the wall and bolted through the holes. When hanging the mount on a railing, the mount is secured to the railing with clamps or cable ties. High-altitude drilling is inconvenient and dangerous, and can damage the wall. Fixing the mount to the railing requires numerous parts and is complex to assemble.

[0047] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., regarding orientations or positions, are based on the orientations or positions shown in the accompanying drawings and are intended solely for ease of description and simplified operation. They do not indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meanings.

[0048] Example 1:

[0049] As shown in FIG1 , this embodiment provides a photovoltaic bracket 100 for mounting a photovoltaic module 200 on a support 300 such as a balcony wall or railing. The photovoltaic module 200 includes a solar panel 210 and a frame 220 . The frame 220 wraps around the solar panel 210 to provide support and protection for the solar panel 210 .

[0050] Specifically, as shown in Figure 1, a photovoltaic support 100 includes a support body 1, a stopper 2, and a connecting assembly 3. The support body 1 is used to support the photovoltaic module 200 to be installed. The stopper 2 is provided on the support body 1 to prevent the photovoltaic module 200 from being separated from the support body 1. The connecting assembly 3 includes a hook 31 and a stopper 32. The hook 31 is connected to the support body 1 and can be hooked to the support body 300. The stopper 32 is provided on the hook 31 and can apply force to both sides of the support body 300 to clamp the support body 300.

[0051] By providing a support body 1 to support the photovoltaic assembly 200, and by using a stopper 2 to limit the photovoltaic assembly 200 on the support body 1, the photovoltaic assembly 200 is securely mounted on the support body 1 and prevented from detaching from the support body 1. A hook 31 is provided to directly attach to the carrier 300, and then a stopper 32 provided on the hook 31 clamps the carrier 300 from both sides, so that the hook 31 is securely fixed to the carrier 300, thereby achieving installation of the entire photovoltaic support 100 and the photovoltaic assembly 200 on the carrier 300. During installation, there is no need to drill mounting holes in the carrier 300, eliminating the need for operators to drill holes on the outside of the carrier 300, reducing costs, steps, and installation safety risks, and protecting the carrier 300 from damage. The photovoltaic support 100 is particularly suitable for installation in high-rise buildings or in environments with limited operating space. Furthermore, it can reduce the number of parts connected to the mounting holes and the number of installation steps, thereby improving installation efficiency.

[0052] Furthermore, as shown in FIG2 , the hook 31 and the bracket body 1 are configured as an integrated structure, eliminating the need for additional assembly of the hook 31 and the bracket body 1. Compared to the prior art structure in which the bracket body 1 is assembled from multiple parts, this saves assembly steps and helps further improve installation efficiency. Furthermore, the integrated structure can enhance the connection strength between the hook 31 and the bracket body 1, improving the stability of the photovoltaic bracket supporting the photovoltaic module 200.

[0053] Specifically, the hook 31 and the bracket body 1 can be integrally processed by casting, or the hook 31 and the bracket body 1 can be integrally connected in advance by welding. The specific connection molding method between the hook 31 and the bracket body 1 is not limited here.

[0054] As shown in Figures 1 and 2, the hook 31 is configured in a U-shape and includes a first side plate 311, a second side plate 312, and a bottom plate 313. The first side plate 311 and the second side plate 312 are respectively disposed at both ends of the bottom plate 313. The first side plate 311 and the second side plate 312 are disposed opposite each other so as to be clamped on both sides of the carrier 300. Specifically, the bottom plate 313 is connected to the upper ends of the first side plate 311 and the second side plate 312. When the hook 31 is hooked to the carrier 300, the first side plate 311 and the second side plate 312 are respectively engaged with the two sides of the carrier 300, so that the bottom plate 313 abuts against the carrier 300, thereby allowing the carrier 300 to vertically support the hook 31, thereby reducing the force applied to the limiting assembly 32 and helping to improve the stability of the installation.

[0055] Furthermore, as shown in FIG2 , the bracket body 1 includes a support plate 11 and a reinforcement plate 13 connected end to end. The support plate 11 and the reinforcement plate 13 are disposed on a side of the second side plate 312 facing away from the first side plate 311 and are connected end to end with the second side plate 312. The support plate 11 is used to support the photovoltaic module 200. The support plate 11, the second side plate 312, and the reinforcement plate 13 are connected end to end to form a triangular structure, which has high structural stability and strength, and can provide a solid support force for the photovoltaic module 200.

[0056] The above-mentioned limiting assembly 32 is provided on the first side plate 311 and the second side plate 312. The second side plate 312 also serves as a part of the bracket body 1. On the one hand, it can simplify the structural design of the photovoltaic bracket 100. On the other hand, it is helpful to reduce the distance between the bracket body 1 and the carrier 300, thereby making the installation of the bracket body 1 on the carrier 300 more stable.

[0057] Of course, in other embodiments, the second side panel 312 can also be set as a longer structure, continuing to extend downward through the position connected to the reinforcement plate 13, so that the hook 31 has a greater depth, thereby being able to have a larger insertion area on the carrier 300, which is beneficial to improving the installation firmness of the hook 31 on the carrier 300.

[0058] Optionally, as shown in Figures 1 and 2, the limiting assembly 32 includes a pre-tightening bolt 321 and a fixing bolt 322, and first threaded holes 310 are respectively provided on the first side plate 311 and the second side plate 312. One of the pre-tightening bolt 321 and the fixing bolt 322 is threadedly connected to the first threaded hole 310 on the first side plate 311, and the other is threadedly connected to the first threaded hole 310 on the second side plate 312.

[0059] As shown in Figure 3, before installing the photovoltaic bracket, the pre-tightening bolts 321 and the fixing bolts 322 can be pre-connected to the corresponding first threaded holes 310, and the distance between the pre-tightening bolts 321 and the fixing bolts 322 is greater than the thickness of the carrier 300. After the hook 31 is hung on the carrier 300, the pre-tightening bolts 321 and / or the fixing bolts 322 are tightened to clamp the carrier 300.

[0060] Specifically, as shown in Figure 3, when the hook 31 is hung on the carrier 300, the second side plate 312 and the bracket body 1 are located outside the carrier 300 to reduce the space occupied indoors. The position limiting assembly 32 on the second side plate 312 is located outside the carrier 300, making it inconvenient to operate. To address this problem, a pre-tightening bolt 321 is provided on the second side plate 312, and a fixing bolt 322 is provided on the first side plate 311. Before the hook 31 is hung on the carrier 300, the pre-tightening bolt 321 is first tightened so that the pre-tightening bolt 321 extends a certain distance into the hook 31, protruding at least from the inner wall of the second side plate 312. The length by which the pre-tightening bolt 321 protrudes from the inner wall of the second side plate 312 is determined by the thickness of the carrier 300. When the hook 31 is attached to the carrier 300, the pre-tightening bolt 321 abuts against the carrier 300. The fixing bolt 322 is then tightened, causing the fixing bolt 322 to press against the pre-tightening bolt 321 against the carrier 300. This allows the fixing bolt 322 and the pre-tightening bolt 321 to cooperate and clamp the carrier 300. Pre-installing the pre-tightening bolt 321 avoids the inconvenience of operating outside the carrier 300.

[0061] Since the walls or railings on the balcony are generally arranged vertically, in order to facilitate the hanging of the hook 31, the U-shaped opening of the hook 31 is vertically downward, and the first side panel 311 and the second side panel 312 extend in the vertical direction. In order to be able to face the direction of light, the photovoltaic assembly 200 generally needs to be tilted. Therefore, the support plate 11 is set to an inclined structure, gradually tilting downward from the end connected to the second side panel 312 to the other end. The reinforcement plate 13 is set at an angle to the support plate 11 to support the downward tilted end of the support plate 11. Of course, the present photovoltaic bracket 100 can also be applied to carriers 300 such as walls or railings that are not completely vertical. It is sufficient to be able to hang the hook 31. The specific structure and angle of the carrier 300 do not affect the installation of the present photovoltaic bracket 100.

[0062] Furthermore, as shown in FIG2 , at least one first threaded hole 310 is provided on the first side plate 311 along its length. When more than one first threaded hole 310 is provided on the first side plate 311, a pre-tightening bolt 321 or a fixing bolt 322 is threadedly connected to any of the first threaded holes 310. Furthermore, at least one first threaded hole 310 is provided on the second side plate 312 along its length. When more than one first threaded hole 310 is provided on the second side plate 312, a pre-tightening bolt 321 or a fixing bolt 322 is threadedly connected to any of the first threaded holes 310. By providing more than one first threaded hole 310 on each of the first side plate 311 and the second side plate 312, the installation position of the limit assembly 32 on the hook 31 can be adjusted according to the structure of the carrier 300, thereby allowing the limit assembly 32 to avoid the hollowed-out position on the carrier 300.

[0063] In this embodiment, three first threaded holes 310 are respectively provided on the first side plate 311 and the second side plate 312 of the hook 31. The three first threaded holes 310 are arranged at intervals along the extension direction of the first side plate 311 or the second side plate 312. Of course, two or more first threaded holes 310 can be provided as needed. There is no limit on the number of the first threaded holes 310 provided.

[0064] In other embodiments, multiple fixing bolts 322 can be set on the first side plate 311, and multiple pre-tightening bolts 321 can be set on the second side plate 312. The multiple fixing bolts 322 and the multiple pre-tightening bolts 321 clamp the carrier 300 at the same time to improve the hanging stability of the hook 31 on the carrier 300.

[0065] Optionally, as shown in FIG2 , the stopper 2 includes a first hook 21, which is integrally formed with the bracket body 1 and is used to prevent the carrier 300 from separating from the bracket body 1. By providing the first hook 21 as an integrally formed structure with the bracket body 1, the structural strength of the first hook 21 is enhanced, thereby providing a more stable and secure stop for the photovoltaic module 200.

[0066] Furthermore, as shown in FIG2 , the limiting member 2 further includes a second hook 22 and a locking member 23 . The first hook 21, the second hook 22, and the bracket body 1 form a limiting groove 20 , into which the photovoltaic module 200 can be inserted. The first hook 21 and / or the second hook 22 are provided with a locking member 23 on the side facing the bracket body 1 , and the locking member 23 is used to lock the photovoltaic module 200. The locking member 23 can specifically be a bolt.

[0067] Optionally, as shown in FIG2 , the bracket body 1 is arranged at an angle relative to the supporting surface of the photovoltaic module 200, and the first hook 21 and the second hook 22 are respectively arranged at both ends of the supporting surface in the inclined direction, and at least one of the first hook 21 and the second hook 22 is provided with a locking member 23. The first hook 21 is provided at the end of the supporting surface that is inclined downward, and the second hook 22 is provided at the end of the supporting surface that is inclined upward, and at least the second hook 22 is provided with a locking member 23.

[0068] In other words, the support plate 11 is tilted. To prevent the photovoltaic module 200 from sliding off the support plate 11, a first hook 21 is provided at the bottom of the support plate 11 to block the photovoltaic module 200, preventing it from sliding downward and keeping it attached to the support plate 11 to prevent it from lifting. A second hook 22 is provided at the top of the support plate 11 to block the top of the photovoltaic module 200, preventing it from flipping over and separating from the support plate 11. A locking member 23 is provided to further lock the photovoltaic module 200 to ensure a secure installation.

[0069] In this embodiment, as shown in Figure 2, the second hook 22 and the bracket body 1 are arranged as a split structure. A second threaded hole 111 is provided on the bracket body 1 opposite the locking member 23. The locking member 23 passes through the second hook 22 and is threadedly connected to the second threaded hole 111. Tightening the locking member 23 can enable the second hook 22 to press the photovoltaic component 200.

[0070] Specifically, the second hook 22 is configured as an L-shaped structure, including a pressing plate 221 and an auxiliary plate 222 that are perpendicular to each other. The locking member 23 is disposed on the pressing plate 221 , and the locking member 23 can be assembled to the second hook 22 in advance.

[0071] Optionally, a plurality of second threaded holes 111 are provided along the extension direction of the bearing surface of the bracket body 1, and the locking member 23 can be threadedly connected to any second threaded hole 111 to adjust the installation position of the second hook 22 on the support plate 11, thereby adjusting the size of the limiting groove 20 surrounded by the first hook 21 and the second hook 22 to accommodate photovoltaic components 200 of different sizes.

[0072] As shown in Figures 3-5 , in one installation method, first, hook 31 is attached to carrier 300 and the stopper assembly 32 is tightened to secure it. Then, without first installing the second hook 22 and locking member 23 on support plate 11, the photovoltaic module 200 is placed on support plate 11, with the bottom end of the photovoltaic module 200 resting against the first hook 21. The second hook 22 is then installed. During installation, the pressing plate 221 is pressed against the surface of the frame 220 of the photovoltaic module 200, the auxiliary plate 222 rests against the support plate 11, and the locking member 23 is passed through the pressing plate 221 and screwed into the second threaded hole 111 until the pressing plate 221 presses against the photovoltaic module 200.

[0073] In another installation method, the locking member 23 is threadedly connected to the second threaded hole 111. There's no need to remove the locking member 23. Instead, simply loosen it, leaving the gap between the pressure plate 221 and the support plate 11 larger than the thickness of the photovoltaic module 200. The photovoltaic module 200 is then inserted from either side of the support plate 11 into the retaining grooves 20 of the first and second hooks 21 and 22, and the locking member 23 is tightened. This installation method eliminates the need for disassembly and assembly of the locking member 23, improving installation efficiency. Furthermore, the locking member 23 and second hook 22 remain attached to the bracket body 1, preventing component loss.

[0074] Furthermore, this embodiment also provides a photovoltaic system, including a photovoltaic component 200 and the above-mentioned photovoltaic bracket 100, and the photovoltaic bracket 100 is provided with at least one group for supporting the photovoltaic component 200. When more than one group of photovoltaic brackets is provided, more than one group of photovoltaic brackets jointly provide support for the photovoltaic component 200.

[0075] Example 2:

[0076] As shown in FIG6 , this embodiment provides a photovoltaic bracket 100 and a photovoltaic system, which are substantially the same as the photovoltaic bracket 100 and the photovoltaic system in the first embodiment, except that:

[0077] When the photovoltaic bracket 100 is installed on a balcony railing or other carrier 300 with a hollow portion, the fixing bolt 322 or the pre-tightening bolt 321 may be aligned with the hollow portion, resulting in the inability of the limit assembly 32 to clamp the carrier 300. To this end, the photovoltaic bracket 100 in this embodiment further includes an optional flat plate 4 that can be positioned to fit the carrier 300. The limit assembly 32 rests on the optional flat plate 4 and forces the inner wall of one side of the hook 31 to press against the carrier 300, thereby allowing the hook 31 and the limit assembly 32 to clamp the optional flat plate 4 and the carrier 300, achieving a secure attachment of the hook 31.

[0078] As shown in Figure 6, the optional flat plate 4 is padded on the inner side of the carrier 300, the second side plate 312 is in contact with the outer side of the carrier 300, and the limiting component 32 on the second side plate 312 passes through the hollow on the carrier 300 and rests on the optional flat plate 4, cooperating with the limiting component 32 on the first side plate 311 to clamp the optional flat plate 4.

[0079] Example 3:

[0080] As shown in FIG7 to FIG9 , this embodiment provides a photovoltaic bracket 100 and a photovoltaic system, which are substantially the same as the photovoltaic bracket 100 and the photovoltaic system in the first embodiment, except that:

[0081] As shown in FIG7 , the second hook 22 and the bracket body 1 are configured as an integrated structure, and the locking member 23 is threadedly connected to the second hook 22. The locking member 23 can press against the photovoltaic module 200 to compress the photovoltaic module 200. Specifically, a third threaded hole 2211 is provided on the pressing plate 221, and the locking member 23 is threadedly connected to the third threaded hole 2211.

[0082] Specifically, the second hook 22 and the support plate 11 can be integrally formed by casting, or the auxiliary plate 222 can be welded to the support plate 11. The hook 31, the bracket body 1, the first hook 21 and the second hook 22 are all integrated structures with good structural strength and do not require assembly before installation.

[0083] As shown in Figures 8 and 9, when installing the photovoltaic component 200, first unscrew the locking piece 23 or rotate the locking piece 23 upward to avoid the limit groove 20, and insert the photovoltaic component 200 into the limit groove 20 from the left and right sides of the photovoltaic bracket 100. After the photovoltaic component 200 is inserted into place, tighten the locking piece 23 so that the locking piece 23 presses the photovoltaic component 200.

[0084] Example 4:

[0085] As shown in Figures 10 to 12, this embodiment provides a photovoltaic bracket 100 and a photovoltaic system, which are the same as the photovoltaic brackets 100 and photovoltaic systems in Example 1, Example 2 and Example 3. The structure of the photovoltaic bracket 100 will not be described in detail here.

[0086] This embodiment primarily improves the structure of photovoltaic assembly 200. Frame 220 is eliminated from photovoltaic assembly 200, with photovoltaic brackets 100 directly supporting solar panels 210, thus reducing the cost of frame 220. Accordingly, the number of photovoltaic brackets 100 is increased to enhance the support strength for solar panels 210. Photovoltaic brackets 100 can be arranged in groups of three, four, five, or more to ensure sufficient support area for solar panels 210.

[0087] Embodiment 5:

[0088] As shown in FIG. 13 , this embodiment provides a photovoltaic bracket 100 and a photovoltaic system, which are substantially the same as the photovoltaic bracket 100 and the photovoltaic system in the first embodiment, except for the structure of the limiting assembly 32 .

[0089] Specifically, the stop assembly 32 includes anti-slip ridges 323 and elastic members 324. The anti-slip ridges 323 are provided on the inner side of one of the first side plate 311 and the second side plate 312, and the elastic member 324 is provided on the other side. When the hook 31 is attached to the carrier 300, the anti-slip ridges 323 and the elastic member 324 respectively abut against the sides of the carrier 300. In this embodiment, the elastic member 324 is provided on the first side plate 311, and the anti-slip ridges 323 are provided on the second side plate 312.

[0090] When the hook 31 is hooked on the carrier 300 , the elastic member 324 will rebound, pressing the carrier 300 against the anti-slip ridges 323 . The elastic member 324 and the anti-slip ridges 323 cooperate to clamp the carrier 300 to fix the hook 31 .

[0091] Specifically, the elastic member 324 includes a telescopic spring 3241 and a pin 3242. The pin 3242 is inserted into the first threaded hole 310. In this case, the first threaded hole 310 can be configured as a blank hole, that is, the first threaded hole 310 can be replaced with a blank hole. The telescopic spring 3241 is sleeved on the end of the pin 3242 that extends into the hook 31. A stopper 3243 is detachably provided at the end of the pin 3242 that extends into the hook 31. The stopper 3243 blocks the telescopic spring 3241 to prevent it from escaping from the pin 3242.

[0092] When the hook 31 is hooked to the carrier 300 , the pin 3242 is squeezed and moves toward the outside of the hook 31 . At this time, the telescopic spring 3241 is compressed to store energy, thereby applying pressure to the carrier 300 .
