Description

Technical Field

[0001] This application relates to the field of photovoltaic equipment technology, and further to a support structure and photovoltaic bracket. Background Technology

[0002] Current photovoltaic (PV) support systems typically consist of purlins and supporting components such as main shafts, which together form the structural foundation of the PV support system. The purlins directly support the PV modules, while the supporting components provide stable anchor points for the purlins, ensuring the stability and durability of the entire system.

[0003] However, the existing connection methods between purlins and supporting components have several limitations. Traditionally, purlins are connected to supporting components (such as spindles) using fasteners. This connection method requires consideration of installation tolerances. During long-term use, the connection points between the fasteners and the spindle often loosen due to environmental factors and mechanical stress. This loosening not only increases maintenance costs but also reduces the stability of the entire structure, potentially adversely affecting the safe operation and lifespan of the photovoltaic system. Furthermore, the use of fasteners can also cause inconvenience during installation, requiring operators to install and assemble them sequentially, increasing construction difficulty and installation time. Utility Model Content

[0004] To address the aforementioned technical problems, the purpose of this application is to provide a support structure and photovoltaic bracket that avoids the use of fasteners to connect purlins and support components, significantly improving the convenience of assembling purlins and support components and the reliability of the overall structure.

[0005] To achieve the above objectives, this application provides a support structure for supporting and fixing photovoltaic modules, comprising: a purlin body and a support member;

[0006] The purlin body has a first connecting portion, and the support member has a second connecting portion. The first connecting portion and the second connecting portion are engaged with each other to limit the displacement of the purlin body along the circumferential direction of the support member.

[0007] In some embodiments, the second connecting portion extends along the length of the support member to both ends of the support member, thereby forming a continuous connecting track on the support member, and the first connecting portion can move along the connecting track to adjust the relative position of the purlin body and the support member.

[0008] In some embodiments, the purlin body includes a body portion and at least one mounting portion. The cross-sectional profile of the body portion is U-shaped. The mounting portion is formed by partially or completely bending a corresponding side of the body portion away from the central axis of the purlin body, and is used to mount photovoltaic modules. The first connecting portion is disposed on the body portion.

[0009] In some embodiments, the first connecting portion is disposed on the bottom wall of the body portion, the bottom wall of the body portion is opposite to the opening of the body portion, and the bottom wall of the body portion and the supporting member at least partially abut against each other.

[0010] In some embodiments, the first connecting portion has a snap-fit ​​end protruding in a direction away from the opening of the body portion, and the second connecting portion has a slot adapted to the snap-fit ​​end, wherein the snap-fit ​​end is embedded in the slot when the purlin body and the support member are connected.

[0011] In some embodiments, the first connecting portion protrudes from its central axis in two opposite directions simultaneously to form a T-shaped snap-fit ​​end, the bottom wall of which is the first end face;

[0012] The slot on the second connecting part is provided corresponding to the snap-fit ​​end, and the bottom wall of the slot is the second end face. When the purlin body and the support member are connected, the first end face and the second end face abut against each other.

[0013] In some embodiments, the first connecting portion further includes a first rolled edge, and the tail end of the snap-fit ​​end is connected to the body portion through the first rolled edge.

[0014] The second connecting part also includes a second rolled edge. The tail end of the slot is connected to the support member through the second rolled edge. When the purlin body and the support member are connected relative to each other, the first rolled edge can fit into the second rolled edge.

[0015] In some embodiments, the purlin body further includes a reinforcing portion, which is disposed outside the body portion and correspondingly disposed above the first connecting portion.

[0016] In some embodiments, the number of purlin bodies is at least two, each purlin body is used to connect to one of the opposite sides of at least one photovoltaic module, and the purlin body is also connected to the support member along the length direction of the support member, so that the opposite sides of the photovoltaic module can be fixed simultaneously by the support structure.

[0017] Another aspect of this application also provides a photovoltaic mounting bracket, comprising:

[0018] At least one pillar;

[0019] The support structure described above, wherein the support member is connected to the top of the column, and the purlin body is used to install photovoltaic modules.

[0020] Compared with the prior art, the support structure and photovoltaic bracket provided in this application have the following advantages:

[0021] By setting corresponding connecting parts on the purlin body and the supporting components, the two can be connected through the interlocking of the connecting parts, eliminating the need for additional fasteners and saving the original connection structures such as clamps and bolts. This effectively avoids structural instability caused by loose fasteners, not only simplifying the installation process, reducing installation time and cost, and improving installation efficiency, but also enhancing the overall stability of the structure and reducing long-term maintenance needs and costs.

[0035] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0036] In solar photovoltaic power generation systems, the stability and reliability of photovoltaic support structures are crucial to the performance of the entire system. They not only need to withstand the static and dynamic loads of photovoltaic modules, but also ensure the stability and durability of the modules under various environmental conditions.

[0037] However, in existing technologies, the connection between purlins and supporting components (such as main shafts and main beams), which are the main supporting structures of photovoltaic systems, largely relies on fasteners. This method requires precise tolerance control during installation, and over long-term use, the connection points between the fasteners and the main shaft are prone to loosening, leading to a decrease in structural stability. Furthermore, the use of fasteners not only increases installation complexity but also raises maintenance costs and workload. Especially under harsh environmental conditions, the risk of fastener failure further increases, affecting the long-term operational efficiency and safety of the photovoltaic system.

[0038] To address the above issues, please refer to the appendix to the instruction manual. Figure 1 This application provides a support structure that aims to improve the reliability of the connection and the overall stability of the structure by improving the connection method between the purlin and the support member, thereby eliminating the dependence on additional fasteners.

[0039] In one embodiment, refer to the appendix to the specification. Figure 1 and Figure 2 The support structure provided in this application includes a purlin body 1 and a support member 2. The purlin body 1 is used to connect photovoltaic modules, while the support member 2 provides the necessary support force for the purlin body 1 to ensure that the photovoltaic modules are stably mounted on the photovoltaic bracket.

[0040] The purlin body 1 is provided with a first connecting part 100, and the support member 2 is provided with a corresponding second connecting part 200. The first connecting part 100 and the second connecting part 200 are matched so that when the purlin body 1 is connected to the support member 2, the first connecting part 100 and the second connecting part 200 can be engaged with each other to limit the displacement of the purlin body 1 along the circumference of the support member 2, thereby effectively preventing the purlin body 1 from falling off the support member 2 and enhancing the stability of the entire structure.

[0041] Understandably, in this embodiment, the snap-fit ​​connection between the first connecting part 100 and the second connecting part 200 significantly improves the connection stability between the purlin body 1 and the support member 2, reduces reliance on traditional fasteners, and thus reduces the risk of structural failure due to fastener loosening or damage. Furthermore, by reducing the use of fasteners, this support structure saves installation costs, improves installation efficiency, and reduces maintenance work required due to fastener loosening or damage, thereby lowering long-term maintenance costs.

[0042] In practice, installers only need to align the purlin body 1 with the support member 2 and snap the corresponding connection parts to complete the connection between the two, which reduces the technical requirements and time cost of installation.

[0043] It should also be noted that, to further enhance the stability of the connection, elastic buffer pads or anti-slip textures can be provided at the snap-fit ​​points. The buffer pads are made of materials with good elasticity and durability, such as rubber or silicone. The buffer pads are located on the surfaces where the first connection part 100 and the second connection part 200 come into contact. They can not only fill any possible small gaps and reduce wear on components caused by vibration or thermal expansion and contraction, but also provide additional friction to prevent the snap-fit ​​points from loosening and to prevent the purlin body 1 from sliding or displacing relative to the supporting member 2 due to external forces (such as wind, earthquakes, etc.).

[0044] Optionally, in one embodiment, the first connecting part 100 is provided with two grooves on its side wall, while the second connecting part 200 is provided with two L-shaped barb structures. When the tail of the barb structure is inserted into the groove, it can form a firm snap-fit ​​to ensure a tight connection between the purlin body 1 and the support member 2.

[0045] In one embodiment, based on the above embodiment, the second connecting portion 200 extends along the length direction of the support member 2 to both ends of the support member 2 to form a continuous connecting track, such that the second connecting portion 200 covers the entire length of the support member 2, and the first connecting portion 100 can move along the connecting track formed by the second connecting portion 200.

[0046] Understandably, during installation, the first connecting part 100 on the purlin body 1 can slide along the connecting track formed by the second connecting part 200 on the support member 2 until it reaches the desired position. This setting in this embodiment provides the support structure with fine-tuning capability during installation, enabling it to achieve precise connection even when faced with size differences or installation errors of photovoltaic modules.

[0047] Specifically, the connecting rail of the second connecting part 200 can be configured with different cross-sectional shapes, such as groove, convex, or concave, to adapt to different installation requirements. The first connecting part 100 is also configured with a corresponding cross-sectional shape to ensure stable sliding on the rail.

[0048] Conversely, the second connecting part 200 has multiple parts and is spaced apart along the length direction of the support member 2, thereby forming multiple discontinuous connection points on the support member 2, and the first connecting part 100 on the purlin body 1 can form a stable connection with any one of these discontinuous connection points.

[0049] In this implementation, the spacing of the second connection 200 can be adjusted according to the length of the support member 2 and installation requirements to ensure that the distribution of connection points is both reasonable and efficient. For example, for a longer support member 2, the spacing of the connection points can be appropriately increased to reduce material usage and maintain structural simplicity; while for areas that require frequent adjustments, denser connection points can be set to provide more installation options.

[0050] In this embodiment, it can be understood that the former, namely the setting of the connecting rail, provides greater installation flexibility and is suitable for scenarios that require frequent adjustments; while the latter, namely the intermittent connection points, improves installation efficiency due to their preset points and is suitable for standardized installation processes.

[0051] In one embodiment, such as Figure 4 As shown, the purlin body 1 includes a body portion 11 and at least one mounting portion 12, wherein the cross-sectional profile of the body portion 11 is U-shaped. The mounting portion 12 is formed by bending from the side of the body portion 11 away from the central axis of the purlin body 1. This bending can be performed on one side to form a single-sided mounting portion 12, or simultaneously on both sides to form a double-sided mounting portion 12.

[0052] When installing photovoltaic modules, the mounting section 12 formed by bending provides a direct fixing point. The photovoltaic modules can be directly fixed to the mounting section 12 using bolts, clamps, or other fasteners, achieving quick and stable installation.

[0053] Meanwhile, the degree of bending of the side of the main body 11 mentioned above can be partial or complete to adapt to different installation requirements and photovoltaic module fixing methods. Specifically, as shown in the figure, two bent portions are formed on one side of the purlin body 1. These two bent portions are the mounting portions 12. In this case, the mounting portions 12 do not completely occupy the entire side of the main body 11, which is a partial bending situation. Of course, in other embodiments, the entire side of the U-shaped cross-section can be bent outward to form a continuous mounting portion 12, providing a larger contact area.

[0054] Furthermore, the bending angle and length of the mounting section 12 can be adjusted according to the size and weight of the photovoltaic modules to ensure optimal load-bearing capacity and installation effect. For example, for heavier photovoltaic modules, the bending length of the mounting section 12 can be increased to provide a larger contact area and stronger fixing force; for lighter modules, a shorter mounting section 12 can be designed to keep the purlin body 1 lightweight.

[0055] Based on the above, in this embodiment, depending on the shape and length of the first connecting part 100, the first connecting part 100 can be flexibly disposed on the side wall or bottom wall of the main body part 11 to adapt to different installation environments and requirements.

[0056] When the first connecting portion 100 is designed to be relatively long, for example, if there are two first connecting portions 100 of suitable length and they are hooks / fasteners, they can be disposed on two opposite side walls of the body portion 11. Both first connecting portions 100 simultaneously connect to the second connecting portion 200 on the support member 2, providing additional stability and support. Conversely, for shorter first connecting portions 100, they can be disposed on the bottom wall of the body portion 11, which helps reduce the relative distance between the purlin body 1 and the support member 2, thus providing convenience in installation environments with limited space or requiring a compact layout.

[0057] Based on the above, in one embodiment, please refer to the appendix to the specification. Figure 1 and Figure 2 The first connecting part 100 is provided on the bottom wall of the main body 11, that is, the bottom of the U-shaped cross section. The bottom wall of the main body 11 and the opening of the main body 11 are opposite each other. When the purlin body 1 is connected to the support member 2, the bottom wall of the main body 11 and the support member 2 are at least partially in contact, ensuring that the force on the photovoltaic module can be effectively transmitted to the support member 2 through the purlin body 1, dispersing the load and enhancing the stability of the entire structure.

[0058] In practical implementation, the position and shape of the first connection portion 100 on the bottom wall can be adjusted according to the size and weight of the photovoltaic module and the expected environmental load. For example, for heavier photovoltaic modules or in areas with high wind load, the area of ​​the first connection portion 100 can be increased to provide a larger contact surface and stronger connection strength. For lightweight modules or in environments with low load, a smaller first connection portion 100 can be designed to maintain the lightweight of the purlin body 1.

[0059] In one embodiment, such as Figure 2 and Figure 3 As shown, the first connecting portion 100 has a snap-fit ​​end 101, which protrudes in a direction away from the opening of the main body portion 11. Correspondingly, the second connecting portion 200 has a slot 201 that matches the shape of the snap-fit ​​end 101. When the purlin body 1 is connected to the support member 2, the snap-fit ​​end 101 can be inserted into the slot 201 to achieve mechanical locking between the two, thereby limiting the displacement of the purlin body 1 along the circumferential direction of the support member 2.

[0060] As can be understood, as shown in the figure, in this embodiment, the inner wall shape of the slot 201 matches the shape of the snap-fit ​​end 101, ensuring the stability of the snap-fit ​​end 101 when it is embedded. Moreover, the use of the snap-fit ​​end 101 and the slot 201 together simplifies the connection steps, reduces installation time, and improves construction efficiency.

[0061] Furthermore, based on this embodiment and the content of the above embodiments, the second connecting portion 200 is continuously arranged along the length direction of the supporting member 2, so that the slot 201 can form a continuous groove-shaped structure, similar to a sliding groove. After the engaging end 101 is engaged into the slot 201 from one side of the supporting member 2, it can slide along the length direction of the slot 201 until it reaches the desired position. Once positioned, the cooperation between the engaging end 101 and the slot 201 can, to a certain extent, limit the offset or detachment of the purlin body 1, ensuring the stability of the connection.

[0062] In practice, the shapes of the snap-fit ​​end 101 and the slot 201 can be adjusted according to actual needs. For example, the snap-fit ​​end 101 can be designed with straight or beveled edges to accommodate different installation angles. The depth and width of the slot 201 can also be adjusted according to the dimensions of the snap-fit ​​end 101 to ensure a tight and stable connection.

[0063] Furthermore, the snap-fit ​​end 101 may have a certain degree of elasticity, allowing it to deform to some extent when embedded in the slot 201, in order to accommodate different installation errors and slight positional changes. The elastic snap-fit ​​end 101 may be made of engineering plastic or metal with good elastic modulus to ensure that it maintains its performance during repeated use.

[0064] Based on the above embodiments, such as Figure 2 As shown, the purlin body 1 also has a reinforcing part 13, which is located outside the body part 11 and is correspondingly located above the first connecting part 100.

[0065] As shown in the attached drawings, the reinforcing part 13 is an additional reinforcement layer, typically made of high-strength steel plate, fixed to the corresponding position of the purlin body 1 by welding or riveting. This enhances the strength of the purlin body 1 at the connection point with the supporting member 2 and in the area above it, preventing stress concentration at the connection point from causing structural deformation or damage. It should be noted that, in addition to common metal materials, the reinforcing part 13 can also be made of composite materials, such as carbon fiber composites, which are not listed here.

[0066] In addition, the shape and outline of the reinforcing part 13 are not limited in this embodiment. The reinforcing part 13 shown in the figure is flat. The flat shape is convenient for processing equipment to operate and the process is relatively simplified. At the same time, the flat reinforcing part 13 will not destroy the original simple lines of the purlin body 1, making the overall appearance more regular and simple. However, the design of the reinforcing part 13 is not limited to flat shape, and can also be curved or other forms to adapt to different application scenarios.

[0067] In one embodiment, based on the above, such as Figure 5As shown, the first connecting portion 100 protrudes simultaneously from its central axis in two opposite directions, forming a T-shaped snap-fit ​​end 101, the bottom wall of which constitutes the first end face 1010. Correspondingly, the snap-fit ​​groove 201 on the second connecting portion 200 is provided correspondingly to the snap-fit ​​end 101, the bottom wall of the snap-fit ​​groove 201 constituting the second end face 2010. When the purlin body 1 is connected to the support member 2, the first end face 1010 and the second end face 2010 can abut against each other, achieving a stable connection.

[0068] Understandably, when the purlin body 1 is connected to the support member 2, the movement of the purlin body 1 in the horizontal and vertical directions can be restricted through the cooperation of the snap-fit ​​end 101 and the snap-fit ​​groove 201.

[0069] Meanwhile, in this embodiment, when the purlin body 1 is connected to the support member 2, the first end face 1010 and the second end face 2010 abut against each other. This arrangement ensures the stability of the connection and increases the frictional force of the connection by expanding the contact area, thereby improving the reliability of the connection. In the drawings of this application, the first end face 1010 and the second end face 2010 are smooth surfaces to facilitate installation and reduce friction. However, in other embodiments, they can also be set as non-smooth surfaces (e.g., with protrusions, grooves, or textures) to increase the coefficient of friction of the contact surface and improve the stability of the connection.

[0070] In addition, to further improve the safety and durability of the connection, anti-slip textures or wear-resistant materials can be added to the contact surfaces of the snap-fit ​​end 101 and the snap-fit ​​slot 201 to increase friction and prevent the connection from loosening due to environmental changes or external forces.

[0071] Of course, in other embodiments, the shape and number of the snap-fit ​​end 101 can be adjusted according to actual needs. For example, the snap-fit ​​end 101 can be set as a disc-shaped flange, which can remain in the slot 201 of the second connection part 200 when the purlin body 1 rotates to a certain extent, and will not come out. At the same time, it provides a larger contact area, increases the friction of the connection, and reduces the risk of connection loosening or falling off due to external force.

[0072] In one embodiment, such as Figure 5 As shown, the first connecting part 100 includes a first rolled edge 102, and the tail end of the snap-fit ​​end 101 and the main body part 11 are connected by the first rolled edge 102. The second connecting part 200 also includes a second rolled edge 202, and the tail end of the slot 201 and the support member 2 are connected by the second rolled edge 202.

[0073] When the purlin body 1 is connected to the support member 2, the first rolled edge 102 and the second rolled edge 202 fit together to ensure the tightness and stability of the connection. More importantly, the rolled edge reduces the right-angle parts on the connection, which can disperse stress, reduce local stress concentration, and improve the service life of the structure.

[0074] In addition, it is understood that the rolled edge in this embodiment is generally formed in production by bending the corresponding connecting part to a certain extent. This bending can be adjusted as needed to form rolled edges of different sizes and shapes, thereby adapting to different connection requirements and load conditions.

[0075] Furthermore, in one embodiment, the bottom wall of the body 11 is provided with a through-hole structure 110 to drain impurities such as dust and rainwater that may be generated inside the purlin body 1, keeping the inside of the purlin body 1 clean, thereby ensuring the long-term stable operation of the photovoltaic support system. The size and shape of the through-hole structure 110 can be designed according to actual needs to ensure that it can effectively drain impurities without affecting the load-bearing capacity of the purlin body 1.

[0076] Based on the above, in one embodiment, the through-hole structure 110 is independently disposed on the bottom wall of the purlin body 1 and maintains a preset distance from the first connecting part 100. In this case, the through-hole structure 110 is directly connected to the internal space of the purlin body 1. In addition, by maintaining a certain preset distance between the through-hole structure 110 and the first connecting part 100, the connecting part can be prevented from being directly impacted by liquid or from accumulating impurities, thereby protecting the integrity and functionality of the connecting part.

[0077] Another implementation scenario is: such as Figure 1 and Figure 4 As shown, the first connecting part 100 has a cavity 103, which is connected to the through-hole structure 110 and the external environment. This implementation can be combined with the above-described embodiment, namely the continuously arranged slots 201. The slots 201 not only form a sliding groove for the engaging end 101 but also form an overall outlet groove for the support member 2. The cavity 103 acts as an intermediate channel, allowing rainwater and other impurities to first flow into the cavity 103 of the first connecting part 100 through the through-hole structure 110 of the purlin body 1, and then drain along the cavity 103 to the outlet groove. This allows rainwater and other impurities to drain along the support member 2, preventing accumulation inside the purlin body 1 and reducing potential corrosion and blockage risks. Alternatively, an additional outlet corresponding to the cavity 103 can be provided on the support member 2, allowing impurities to drain from that location.

[0078] It should be noted that all of the above methods can effectively remove impurities and rainwater, reduce the potential impact on the performance of the photovoltaic support system, and improve the stability and reliability of the entire system. In specific implementation, the most suitable placement method can be selected according to the design of the purlin body 1 and the usage environment.

[0079] Based on the above embodiments, it should also be noted that, in this application, as Figure 6 As shown, the support structure can fix the photovoltaic module to the opposite sides through two purlin bodies 1.

[0080] Specifically, each purlin body 1 can connect to at least one of the opposite sides of a photovoltaic module. If the purlin body 1 is provided with mounting parts 12 on both sides, one purlin body 1 can also connect to the sides of two different photovoltaic modules simultaneously, thereby improving the utilization rate of the purlin body 1. The purlin bodies 1 are arranged along the length of the supporting member 2, and the spacing between two adjacent purlin bodies 1 is approximately equal to the width of the photovoltaic module. The spacing between purlin bodies 1 can also be adjusted as needed to adapt to different installation conditions and the size of the photovoltaic module. Similarly, the number of purlin bodies 1 can be adjusted according to the size and weight of the photovoltaic module.

[0081] In one embodiment, according to another aspect of this application, this application further provides a photovoltaic support structure, including at least one column and the aforementioned support structure.

[0082] The purlin body 1 is used to install photovoltaic modules, and the support member 2 is connected to the top of the column, so that when the purlin body 1 and the support member 2 are connected, a continuous support path can be formed, thereby effectively supporting the photovoltaic modules. The support structure is connected by a snap-fit ​​connection between the first connecting part 100 and the second connecting part 200, achieving a stable fixing method without fasteners. This reduces maintenance work caused by loose or damaged fasteners, lowers maintenance costs, simplifies the installation process of the photovoltaic bracket, reduces installation time and labor costs, and improves the overall reliability and economy of the photovoltaic bracket.

[0083] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this application. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
