Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module installation structure technology, specifically to a photovoltaic horizontal module support drainage device and a photovoltaic module having the same. Background Technology

[0002] Photovoltaic power generation, as a clean and renewable energy source, has been widely used globally. With advancements in photovoltaic technology, the efficiency of photovoltaic modules has continuously improved, and installation methods have become increasingly diversified. To enhance the installation efficiency and long-term stability of photovoltaic power generation systems, the design and material selection of photovoltaic modules have become particularly important. In photovoltaic modules, purlins, as one of the components that directly contact the photovoltaic frame, play a crucial role.

[0003] Purlins are important structural components in photovoltaic modules used to support and fix the photovoltaic frame. They are usually part of the photovoltaic frame and work with other support systems (such as columns, beams, etc.) to ensure that the photovoltaic modules are stably fixed after installation and have sufficient strength to withstand the pressure of the external environment, such as wind and snow loads. At the same time, purlins must also have drainage function to ensure the normal use of photovoltaic modules and extend their service life.

[0004] In related technologies, drainage is usually achieved by using V-shaped drainage channels inside M-shaped purlins. However, in areas with heavy rainfall, the drainage volume increases, which can lead to untimely drainage. At the same time, since M-shaped purlins are usually made of thin steel plates formed by stamping, they are more susceptible to deformation under overload external forces, which can easily lead to structural instability and further affect the drainage performance of the V-shaped drainage channels. Utility Model Content

[0005] In view of this, the present invention provides a photovoltaic horizontal module support drainage device and a photovoltaic module having the same, so as to solve the problem of poor waterproof performance when the photovoltaic module is installed on the short side.

[0006] In a first aspect, this utility model provides a photovoltaic horizontal module support and drainage device, comprising:

[0007] U-shaped purlins, the inner side of which is suitable for forming a drainage groove;

[0008] The bracket body is fixedly installed on the top of the U-shaped purlin, and the bracket body is fixedly connected to the U-shaped purlin;

[0009] The pressure block body is fixedly installed on the side of the bracket body facing away from the U-shaped purlin, and the pressure block body is arranged along the length of the U-shaped purlin.

[0010] The photovoltaic horizontal module support and drainage device provided by this utility model, when used to install photovoltaic modules on a roof, features U-shaped purlins fixedly connected to the roof's inclined beams via external fastening components. The outer edge of the photovoltaic module's frame is pressed between the pressure block body and the bracket body. By arranging the pressure block body along the length of the U-shaped purlin, the U-shaped purlin is positioned perpendicular to the gap between the photovoltaic modules during installation. By setting the drainage structure to a U-shape, compared to the M-shaped purlins in the prior art, the drainage structure within the purlin is widened, increasing the drainage capacity. The U-shaped purlin has drainage channels inside, which are suitable for draining accumulated rainwater and dirt, while also providing a supporting structure for the photovoltaic modules. The bracket body is fixed to the top of the U-shaped purlin and is fixedly connected to it. The bracket body plays a load-bearing role and abuts against the horizontal photovoltaic modules. The top of the bracket body also abuts against the pressure block body. The pressure block body and the bracket body together press the horizontal photovoltaic modules. The wide surface at the bottom of the U-shaped purlin abuts against the roof beam. Under the pressure of the photovoltaic modules, the wide contact surface of the U-shaped purlin allows it to be stably supported on the roof beam, ensuring the stability of the U-shaped purlin. This prevents water from overflowing from the sides of the purlin due to deformation, ensuring that the drainage device supporting the horizontal photovoltaic modules can maintain good drainage performance.

[0011] In one alternative embodiment, a fixing member is provided, which at least abuts against the bottom of the U-shaped purlin, and the fixing member is fixedly connected to the bracket body by fasteners.

[0012] The fixed mounting component can be a flat plate structure. The bracket body is fixed to the fixed mounting component using fasteners such as long bolts, so that the U-shaped purlin is fixedly installed between the fixed mounting component and the bracket body, making the support structure of the U-shaped purlin and the bracket body more stable. The fixed mounting component and the bracket body are fixedly connected by fasteners. The fixed mounting component covers part of the outer wall of the U-shaped purlin and is locked by fasteners to achieve a better fixed connection effect.

[0013] In one alternative embodiment, the fixing device and the bracket body enclose an installation space, and the U-shaped purlin is installed in the installation space, with the fixing device abutting against the outer wall of the U-shaped purlin.

[0014] The fixing component can be a U-shaped structure. The fixing component and the bracket body enclose an installation space. The installation space is suitable for accommodating the U-shaped purlin. The fully enclosed structure of the installation space makes the U-shaped purlin installation more stable. The fixing component and the outer wall of the U-shaped purlin fit together, making the connection between the U-shaped purlin and the bracket body more stable.

[0015] In one alternative embodiment, mounting portions are provided on both sides of the fixed mounting member, with the mounting portions extending toward the side away from the U-shaped purlin, and the bracket body and the mounting portions are fixedly connected by fasteners.

[0016] By setting an outwardly bent mounting part, when the fixed mounting part is fixedly connected to the bracket body, the mounting part parallel to the bracket body cooperates with the bracket body, and then the two are fixedly connected by bolts and other fasteners. This can greatly reduce the installation difficulty when the bracket body and the fixed mounting part are fixed together, while ensuring the stability of the bracket body installation. The fasteners pass through the mounting part and the bracket body, which enhances the structural rigidity and makes the structure more stable.

[0017] In one alternative embodiment, a reinforcing rib is provided between the mounting portion and the side wall of the fixed mounting component.

[0018] A reinforcing rib is provided between the mounting part and the side wall of the fixed mounting component. The reinforcing rib can enhance the load-bearing capacity and stability of the bracket body. When subjected to external forces such as pressure, bending, and torsion, the reinforcing rib can effectively disperse these forces and transfer them to the overall structure, thereby protecting the bracket body from damage.

[0019] In one alternative embodiment, multiple fixing members and bracket bodies are spaced apart along the length of the U-shaped purlin.

[0020] Multiple fixed mounting components are spaced apart along the length of the U-shaped purlin, which improves the stability of the mounting structure between the bracket body and the U-shaped purlin, and also makes the exterior of the bracket body more stable.

[0021] In one alternative embodiment, the fastener passes through the pressure block body, the bracket body, and the fixing device in sequence to securely connect the pressure block body, the bracket body, and the fixing device.

[0022] The pressure block body is located on top of the bracket body and abuts against the bracket body. Fasteners pass through the pressure block body, bracket body and fixed mounting parts in sequence, improving the stability of the fastening connection between the pressure block body, bracket body and fixed mounting parts.

[0023] In one alternative embodiment, the U-shaped purlin includes an inner layer sheet and an outer layer sheet that are fitted together, the inner layer sheet and the outer layer sheet being fixedly connected, and the outer layer sheet being adapted to be installed in conjunction with an external mounting structure.

[0024] The inner and outer layers of the sheet metal allow for separation between the connection and drainage sections of the U-shaped purlin, while the double-layer structure also helps improve the load-bearing capacity of the U-shaped purlin.

[0025] In one alternative embodiment, an auxiliary groove is provided on the side of the bracket body facing the U-shaped purlin.

[0026] An auxiliary groove is provided on the side of the bracket body facing the U-shaped purlin, which makes the thickness of the part of the bracket body that abuts against the U-shaped purlin thicker than the rest of the bracket body facing the U-shaped purlin, thus improving the stability of the connection. At the same time, the auxiliary groove can also save on processing material costs and reduce the amount of steel used.

[0027] Secondly, this utility model also provides a photovoltaic module, including the photovoltaic horizontal module support and drainage device described in this utility model.

[0028] Since the photovoltaic modules include a photovoltaic horizontal module support drainage device, which has the same effect as the photovoltaic horizontal module support drainage device, it will not be described in detail here. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0039] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0040] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0041] Photovoltaic modules need to cope with natural factors such as wind, rain, and snow during use. Since photovoltaic modules are generally installed outdoors, drainage issues need to be considered during installation. Excessive rainfall may cause rainwater to accumulate on the photovoltaic modules, and moisture may cause electrical faults or short circuits in the photovoltaic modules, increasing the difficulty of maintenance and reducing the power generation efficiency of the photovoltaic modules.

[0042] Purlins are an important component of photovoltaic modules, used to support and fix the photovoltaic modules. The main function of purlins is to distribute the weight of the photovoltaic modules evenly across the entire purlin, preventing the photovoltaic modules from moving or falling off, while also draining moisture flowing through the photovoltaic modules and protecting them from damage.

[0043] The following is combined with Figures 1 to 4 The following describes embodiments of the present invention.

[0044] According to an embodiment of the present invention, a photovoltaic frame drainage device is provided, comprising a U-shaped purlin 1, a bracket body 2, and a pressure block body 3.

[0045] The inner side of the U-shaped purlin 1 is adapted to form a drainage groove 11. The bracket body 2 is fixedly installed on the top of the U-shaped purlin 1, and the bracket body 2 is fixedly connected to the U-shaped purlin 1. The pressure block body 3 is fixedly installed on the side of the bracket body 2 facing away from the U-shaped purlin 1, and the pressure block body 3 is arranged along the length direction of the U-shaped purlin 1.

[0046] The photovoltaic horizontal module support and drainage device provided by this utility model, when used to install photovoltaic modules on a roof, has a U-shaped purlin 1 fixedly connected to the roof beam via an external fastening component. The outer edge of the back of the photovoltaic module frame is pressed and installed between the pressure block body 3 and the bracket body 2. By setting the pressure block body 3 to be arranged along the length direction of the U-shaped purlin 1, the U-shaped purlin 1 is arranged perpendicular to the gap between the photovoltaic modules during installation. By setting the drainage structure to U-shape, compared with the M-shaped purlin in the prior art, the drainage structure in the purlin is widened, which can increase the drainage volume. The U-shaped purlin 1 forms a drainage groove 11 inside, which is suitable for draining accumulated rainwater and dirt, and at the same time provides a support structure for the photovoltaic module. The bracket body 2 is fixed to the top of the U-shaped purlin 1 and is fixedly connected to the U-shaped purlin 1. The bracket body 2 plays a load-bearing role and abuts against the photovoltaic horizontal module. The top of the bracket body 2 also abuts against the pressure block body 3. The pressure block body 3 and the bracket body 2 together press the photovoltaic horizontal module. The pressure block body 3 is arranged along the length direction of the U-shaped purlin 1, and the length direction of the U-shaped purlin 1 is perpendicular to the horizontal direction of the photovoltaic horizontal module. The wide surface at the bottom of the U-shaped purlin 1 abuts against the roof sloping beam. Under the pressure of the photovoltaic modules, the wide abutment surface of the U-shaped purlin 1 allows it to be stably supported on the roof sloping beam, ensuring its stability. This prevents water from overflowing from the side of the purlin due to deformation, thus ensuring that the drainage device supporting the photovoltaic horizontal modules maintains good drainage performance.

[0047] As one implementation, the bracket body 2 extends beyond the U-shaped purlin 1 on both sides along the width direction of the U-shaped purlin 1. The width of the bracket body 2 is not less than the opening width of the U-shaped purlin 1, so that the bracket body 2 can completely cover the opening end of the U-shaped purlin 1. Furthermore, the fact that the bracket body 2 extends beyond the U-shaped purlin 1 on both sides along the width direction of the U-shaped purlin 1 enhances the balance and makes the connection between the bracket body 2 and the U-shaped purlin 1 more stable.

[0048] As one implementation, the pressing surface of the pressing block body 3 has protrusions on one side to increase friction and prevent pressing failure.

[0049] In some embodiments, combined with Figure 1As shown, the fixing component 4 at least abuts against the bottom of the U-shaped purlin 1, and the fixing component 4 is fixedly connected to the bracket body 2 by fasteners 6.

[0050] The fixing mounting part 4 is suitable for connecting the U-shaped purlin 1 to the bracket body 2, making the support structure of the U-shaped purlin 1 and the bracket body 2 more stable. The fixing mounting part 4 and the bracket body 2 are fixedly connected by fasteners 6. The fixing mounting part 4 covers part of the outer wall of the U-shaped purlin 1 and is locked by fasteners 6 to achieve a better fixed connection effect.

[0051] In this embodiment, combined with Figure 1 As shown, the fixing mounting component 4 and the bracket body 2 form an installation space, and the U-shaped purlin 1 is installed in the installation space. The fixing mounting component 4 fits and abuts against the outer wall of the U-shaped purlin 1.

[0052] The fixing mounting component 4 and the bracket body 2 form an installation space. The interior of the installation space is suitable for accommodating the U-shaped purlin 1. The fully enclosed structure of the installation space makes the installation of the U-shaped purlin 1 more stable. The fixing mounting component 4 fits and abuts against the outer wall of the U-shaped purlin 1, making the installation connection between the U-shaped purlin 1 and the bracket body 2 more stable.

[0053] In one implementation, the fixing component 4 is a clamp that encloses the U-shaped purlin 1 and is fixedly connected to the bracket body 2. It is locked by fasteners 6, which are bolt and nut connectors that connect the bracket body 2 and the clamp. In some other embodiments, the fixing component 4 can also be a flat plate structure, which is fixed to the bracket body 2 by long bolts.

[0054] Furthermore, combined Figure 2 As shown, in order to facilitate the fixed engagement between the fixed mounting part 4 and the bracket body 2, mounting parts 41 are provided on both sides of the fixed mounting part 4. The mounting parts 41 extend toward the side away from the U-shaped purlin 1. The bracket body 2 and the mounting parts 41 are fixedly connected by fasteners 6. The bolts, which are fasteners 6, pass through the mounting parts 41 and the bracket body 2 in sequence and are then fastened together by engaging with nuts.

[0055] The mounting part 41 is designed to connect the bracket body 2 and the fixed mounting part 4, while ensuring the stability of the bracket body 2 during installation. The fastener 6 passes through the mounting part 41 and the bracket body 2 to enhance the structural rigidity and make the structure more stable.

[0056] As one implementation, the mounting part 41 is a connecting folded edge of the clamp. The connecting folded edge is bent toward the side of the clamp away from the U-shaped purlin 1. The connecting folded edge is connected to the bracket body 2, which enhances the tightness of the contact between the connecting folded edge and the U-shaped purlin 1 and the bracket body 2, and facilitates disassembly and installation.

[0057] As an alternative implementation, the mounting part 41 is provided on one side of the clamp, and the mounting part 41 extends in a direction away from the U-shaped purlin 1 and is fitted and connected to the side wall of the bracket body 2. The bolts, which are fasteners 6, pass through the mounting part 41 and the side wall of the bracket body 2.

[0058] In some embodiments, combined with Figure 2 As shown, in order to improve the stability of the mounting part 41 and the fixed mounting part 4 and to prevent the mounting part 41 from deforming under pressure, a reinforcing rib 5 is provided between the outer wall of the mounting part 41 and the fixed mounting part 4.

[0059] A reinforcing rib 5 is provided between the mounting part 41 and the side wall of the fixed mounting part 4. The reinforcing rib 5 can enhance the load-bearing capacity and stability of the bracket body 2. When subjected to external forces such as pressure, bending, and torsion, the reinforcing rib 5 can effectively disperse these forces and transfer them to the overall structure, thereby protecting the bracket body 2 from damage.

[0060] The reinforcing ribs 5 abut against the fixed mounting part 4 and the mounting part 41 respectively, forming an angle between the fixed mounting part 4 and the mounting part 41, and the reinforcing ribs 5 are provided.

[0061] In some embodiments, combined with Figure 2 As shown, multiple fixing mounting parts 4 and bracket body 2 are spaced apart along the length of U-shaped purlin 1. By spaced multiple fixing mounting parts 4 and bracket body 2 along the length of U-shaped purlin 1, the stability of the bracket body 2 and U-shaped purlin 1 installation structure can be improved, and the external structure of bracket body 2 can be made more stable.

[0062] In some embodiments, combined with Figure 2 As shown, the fastener 6 passes through the pressure block body 3, the bracket body 2, and the fixing mounting part 4 in sequence to securely connect the pressure block body 3, the bracket body 2, and the fixing mounting part 4. When the photovoltaic horizontal module support drainage device is used with the photovoltaic module, after placing the outer edge of the frame on the back of the photovoltaic module between the pressure block body 3 and the bracket body 2, the bolt, which acts as the fastener 6, passes through the mounting part 41 of the pressure block body 3, the bracket body 2, and the fixing mounting part 4, and is then locked in place with a nut. This allows the photovoltaic horizontal module support drainage device to be quickly and securely fitted with the photovoltaic module.

[0063] The pressure block body 3 is located on the top of the bracket body 2 and abuts against the bracket body 2. The fastener 6 passes through the pressure block body 3, the bracket body 2 and the fixing installation part 4 in sequence, which improves the stability of the fastening connection between the pressure block body 3, the bracket body 2 and the fixing installation part 4.

[0064] Optionally, the connection method for fastening the pressure block body 3, the bracket body 2, and the fixing installation part 4 can be snap-fit, adhesive, or bolted. In this solution, bolted connection is preferred.

[0065] In some embodiments, combined with Figure 3 As shown, the U-shaped purlin 1 includes an inner layer plate 12 and an outer layer plate 13 that fit together. The inner layer plate 12 and the outer layer plate 13 are fixedly connected, and the outer layer plate 13 is adapted to be installed with an external mounting structure. The inner layer plate 12 forms an internal drainage channel 11, and the outer layer plate 13 has through holes for bolting to an L-shaped adapter plate for installation on the roof beam. During installation, one side of the L-shaped adapter plate is first fixed to the roof beam, and then the through holes on the outer layer plate 13 are aligned with the mating holes on the other side of the L-shaped adapter plate before being tightened with bolts. The inner layer plate 12 and the outer layer plate 13 separate the connecting part of the U-shaped purlin 1 from the drainage part, preventing leakage from the drainage channel 11 caused by the through holes. The double-layer structure also helps improve the load-bearing capacity of the U-shaped purlin 1.

[0066] As one implementation, the U-shaped purlin 1 is a solid structure, integrally formed, with a U-shaped cross-section perpendicular to its length. Specifically, the U-shaped purlin 1 is made of soft metal materials such as aluminum alloy and is formed in one stamping process.

[0067] In some embodiments, combined with Figure 3 As shown, in order to reduce the amount of steel used in the bracket body 2, an auxiliary groove is provided on the side of the bracket body 2 facing the U-shaped purlin 1.

[0068] An auxiliary groove is provided on the side of the bracket body 2 facing the U-shaped purlin 1, which makes the thickness of the part of the bracket body 2 that abuts against the U-shaped purlin 1 thicker than the rest of the side of the bracket body 2 facing the U-shaped purlin 1, thereby improving the stability of the connection. At the same time, the setting of the auxiliary groove can also save processing material costs.

[0069] According to an embodiment of this utility model, another aspect provides a photovoltaic module, including the aforementioned photovoltaic horizontal module support and drainage device. During installation, the U-shaped purlin 1 is fixedly connected to the roof beam via external fastening components. The outer edge of the back of the photovoltaic module frame is pressed between the pressure block body 3 and the bracket body 2. By arranging the pressure block body 3 along the length of the U-shaped purlin 1, the U-shaped purlin 1 is arranged perpendicular to the gap between the photovoltaic modules during installation. By setting the drainage structure to U-shape, compared to the M-shaped purlin in the prior art, the drainage structure in the purlin is widened, increasing the drainage capacity.

[0070] This solution is applicable to the fixed connection of the short side frames of adjacent photovoltaic modules. The pressure block body 3 is arranged along the length direction of the U-shaped purlin 1. Optionally, the connection structure of the long side frames of adjacent photovoltaic modules can be selected as the pressure block body 3 is arranged along the width direction of the U-shaped purlin 1.

[0071] Obviously, the above embodiments are merely examples for clear illustration and are not intended to limit the implementation. Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and all such modifications and variations fall within the scope defined by the present invention.
