Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, specifically to a front column of a highly adaptable photovoltaic ballast system. Background Technology

[0002] Distributed photovoltaic (PV) systems are increasingly being used on urban building rooftops and in industrial and commercial buildings. These locations have varying roof structures and load-bearing capacities, and many buildings cannot withstand the weight of traditional large ballast loads. Portable ballast loads can flexibly adjust their weight and position according to the actual load-bearing capacity of the roof and the layout requirements of the PV system, achieving safe and efficient installation. The front support column, as the core component supporting the PV modules, directly affects the system's installation efficiency, stability, and applicability. However, existing front support columns suffer from the following technical shortcomings:

[0003] 1. Insufficient stability due to multi-component splicing: The existing front column is a split structure. The splicing points of each component are prone to structural deformation due to stress concentration or environmental loads, which affects the positioning accuracy and wind uplift resistance of the photovoltaic modules.

[0004] 2. Limited structural functionality and poor adaptability: Traditional front-mounted supports typically only employ a unidirectional locking design for the long or short side of the photovoltaic module, resulting in the incompatibility of the same support system with photovoltaic modules of different installation orientations or sizes. To accommodate diverse module specifications, multiple support systems need to be developed, significantly increasing production costs and inventory management complexity.

[0005] 3. Redundant grounding design, safety needs to be improved: The existing front column lacks an integrated conductive design, and relies on external grounding wires or additional components to achieve conductive connection of components. This not only increases the installation steps, but also poses a risk of conductive failure due to grounding component detachment or oxidation, affecting the system's lightning protection performance and long-term operational safety.

[0006] In view of this, the inventor conducted in-depth research on the aforementioned deficiencies in the prior art, which led to the creation of this case. Utility Model Content

[0007] The main purpose of this utility model is to provide a highly adaptable front column for a photovoltaic ballast system. By integrating the long-side pressure part and the short-side pressure part, the structural strength and overall stability of the front column are significantly improved, avoiding the deformation risk caused by split splicing. At the same time, the integrated design supports the universal locking function of the long and short sides of the photovoltaic module, which can be adapted to photovoltaic modules of different sizes and installation directions without replacing parts, reducing production costs and inventory management difficulties.

[0008] To achieve the above objectives, the solution of this utility model is: a front column of a highly adaptable photovoltaic ballast system, comprising a long side pressure section and a short side pressure section, wherein the long side pressure section and the short side pressure section are integrally formed.

[0009] Furthermore, the long-side pressure portion is laterally hollow and has a first T-shaped groove formed on its top surface for mates with the common middle pressure portion; the short-side pressure portion is laterally hollow and has a second T-shaped groove formed on its top surface for mates with the common middle pressure portion.

[0010] Furthermore, the long side pressure part is provided with a first bolt hole for locking with the ballast bottom beam, and the short side pressure part is provided with a second bolt hole for locking with the side wind deflector.

[0011] Furthermore, the top surface of the front column is a supporting slope, and a vertical plate for limiting the photovoltaic module is provided on the supporting slope.

[0012] Furthermore, the inclination angle of the supporting slope is 10° or 15°.

[0013] Furthermore, the front column also includes a splicing part integrally formed with the long side pressure part.

[0014] Furthermore, the splicing part has a lateral hollow design and includes a guide groove and a bolt groove, wherein the guide groove is inclined and connected to the bolt groove.

[0015] Furthermore, at least two first conductive spikes are provided on one side of the front pillar; at least two second conductive spikes are provided on the top surface of the short side pressure portion.

[0016] Furthermore, the number of the first conductive spikes is 2, and the number of the second conductive spikes is 2.

[0017] The advantages of this utility model are:

[0018] 1. The front column significantly improves the structural strength and overall stability of the front column by integrating the long side pressure part and the short side pressure part, avoiding the deformation risk caused by split splicing; at the same time, the integrated design supports the universal locking function of the long side and short side of the photovoltaic module, which can be adapted to photovoltaic modules of different sizes and installation directions without replacing parts, reducing production costs and inventory management difficulty.

[0019] 2. The hollow design of the long side pressure section and the short side pressure section reduces weight, and the first T-shaped slot and the second T-shaped slot on the top surface enable quick snap-fit ​​with the common middle side pressure combination, simplifying the installation and positioning process and improving construction efficiency; the standardized interface design of the double T-shaped slot unifies the long and short side clamping method, ensuring uniform distribution of clamping force and reducing the risk of photovoltaic module frame deformation.

[0020] 3. The first and second conductive spikes are integrated into the front column body, directly piercing the oxide layer of the photovoltaic module frame or the ballast bottom beam to achieve a reliable conductive connection, eliminating the need for external grounding. The integrated design avoids the risk of grounding components falling off, improving the system's lightning protection performance and long-term operational safety. Attached Figure Description

Detailed Implementation

[0028] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0029] like Figures 1 to 6 As shown, this utility model provides a front support column 100 for a highly adaptable photovoltaic ballast system, including a long-side pressure section 1 and a short-side pressure section 2, which are integrally formed. The long-side pressure section 1 is used to cooperate with the common middle-side pressure assembly 400 to lock the long side 201 of the photovoltaic module 100, and the short-side pressure section 2 is used to cooperate with the common middle-side pressure assembly 400 to lock the short side 202 of the photovoltaic module 100.

[0030] The front column 100 of this utility model significantly improves the structural strength and overall stability of the front column 100 by integrating the long side pressure part 1 and the short side pressure part 2, avoiding the deformation risk caused by split splicing; at the same time, the integrated design supports the universal locking function of the long and short sides of the photovoltaic module 200, which can be adapted to photovoltaic modules of different sizes and installation directions without replacing parts, reducing production costs and inventory management difficulty.

[0031] In this invention, the long-side pressing part 1 is laterally hollow, and its top surface has a first T-shaped groove 11 for engaging with the common middle-side pressing assembly 400; the short-side pressing part 2 is laterally hollow, and its top surface has a second T-shaped groove 21 for engaging with the common middle-side pressing assembly 400. The hollow design of the long-side pressing part 1 and the short-side pressing part 2 reduces weight while enabling quick engagement with the common middle-side pressing assembly 400 via the first T-shaped groove 11 and the second T-shaped groove 21 on the top surface, simplifying the installation and positioning process and improving construction efficiency. The standardized interface design of the double T-shaped grooves unifies the long and short side pressing methods, ensuring uniform distribution of pressing force and reducing the risk of deformation of the photovoltaic module 200 frame.

[0032] In this invention, the long-side pressure part 1 has a first bolt hole 12 for locking with the ballast base beam, and the short-side pressure part 2 has a second bolt hole 22 for locking with the side baffle. The first bolt hole 12 for locking the long-side pressure part 1 with the ballast base beam and the second bolt hole 22 for locking the short-side pressure part 2 with the side baffle are designed with pre-set positions, achieving modular connection, reducing on-site drilling, and improving assembly accuracy. The multi-functional locking design avoids force interference and enhances structural stability. The front column 100 is locked to the ballast base beam 300 by the locking assembly 500, which passes through the ballast base beam 300 and the first bolt hole 12 sequentially. The locking assembly 500 consists of bolts, flat washers, and spring washers, and is existing technology.

[0033] In this invention, the top surface of the front column 100 is a supporting slope, and a vertical plate 3 for limiting the photovoltaic module 200 is provided on the supporting slope. The integrated design of the supporting slope and the vertical plate 3 provides physical limitation for the photovoltaic module 200, preventing the module from sliding along the slope under wind load or vibration, and ensuring installation accuracy; the inclined top surface naturally guides water, reducing the risk of water accumulation and corrosion, and extending service life.

[0034] In this invention, the inclination angle of the supporting slope is 10° or 15°. The inclination angle of the supporting slope is limited to 10° or 15°, covering the optimal power generation angle requirements of mainstream photovoltaic modules 200. This allows for adaptation to different regional lighting conditions without the need for additional adjustment components, reducing system complexity and cost.

[0035] In this invention, the front column 100 also includes a splicing part 4 integrally formed with the long side pressure part 1. The splicing part 4 is integrally formed with the long side pressure part 1, which further optimizes the structural integration and enhances the convenience of expanding the connection of the ballast bottom beam; the integrated design avoids stress concentration problems caused by splicing gaps and improves the overall bending resistance.

[0036] In this invention, the splicing part 4 is laterally hollow and includes a guide groove 41 and a bolt groove 42. The guide groove 41 is inclined and connected to the bolt groove 42. The inclined guide groove 41 of the splicing part 4, connected to the bolt groove 42, guides the bolts to automatically slide into the groove, enabling rapid alignment and splicing of adjacent front columns; the hollow structure reduces weight and provides operating space.

[0037] In this invention, at least two first conductive spikes 5 are provided on one side of the front column 100; at least two second conductive spikes 6 are provided on the top surface of the short side pressure part 2. The first conductive spikes 5 and the second conductive spikes 6 are integrated into the front column body, directly piercing the oxide layer of the photovoltaic module frame or the ballast bottom beam to achieve a reliable conductive connection, eliminating the need for an external grounding step; the integrated design avoids the risk of grounding components falling off, improving the system's lightning protection performance and long-term operational safety.

[0038] The front support column 100 of the highly applicable photovoltaic ballast system of this utility model solves the problems of simple structure, unstable splicing, poor angle adaptability and grounding redundancy of the front support column in the prior art, and fully demonstrates the significant advantages of this utility model in improving versatility, installation efficiency and safety.

[0039] The shared middle-side pressure assembly 400 includes a basic card block 401 and a shared pressure block 402 that cooperates with the basic card block 401 to press the long and short sides of the photovoltaic module 200 together.

[0040] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
