Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, and in particular to a wall-mounted photovoltaic installation assembly for factory facades. Background Technology

[0002] With the rapid development of the photovoltaic industry, factories, as major energy consumers, urgently need to install photovoltaic modules in their idle spaces to achieve energy self-sufficiency and reduce energy costs. However, current photovoltaic installation solutions for factory facades suffer from the following key technical problems, making it difficult to meet practical application needs: Poor installation adaptability, unable to match the complex load-bearing structure of factory facades: Factory facades often include different types of load-bearing structures such as steel columns and hardened ground. Existing photovoltaic mounting bases are mostly single structures, unable to stably connect to both steel columns and hardened ground simultaneously, resulting in limited installation locations and potential structural safety hazards due to improper selection of load-bearing points. Insufficient stability of the main steel structure connection, weak load-bearing capacity: Factory areas often face complex weather conditions such as strong winds and snow accumulation. In existing installation solutions, the connection between steel columns and main beams often uses simple welding or single bolt fixing, lacking dedicated rigid connectors. This easily leads to loosening of connection nodes, failing to effectively transfer wind loads, snow loads, and the self-weight of photovoltaic modules, and is prone to structural deformation with long-term use. The installation of photovoltaic modules suffers from low precision, susceptibility to misalignment, and insufficient protection: Existing module installation structures lack adjustable positioning components for the connections between columns and main beams / crossbeams, making it impossible to fine-tune the position according to the module dimensions, leading to misalignment during splicing. Furthermore, the horizontal and vertical splicing points rely solely on simple pressure plates for fixation, lacking dedicated cover seals. This allows rainwater to easily seep into the splicing seams, corroding the module frames and connecting bolts, and shortening the lifespan of the photovoltaic modules. The nodes exhibit poor vibration resistance and weak adaptability to factory operating conditions: Low-frequency vibrations are generated during equipment operation in factory production. Existing installation solutions lack anti-slip and anti-loosening structures for connection nodes such as corner brackets and pressure plates. Long-term vibration can easily lead to loose bolts and module misalignment, affecting the flatness of the photovoltaic module installation, power generation efficiency, and even causing safety accidents.

[0003] Therefore, there is an urgent need to provide a factory facade wall-mounted photovoltaic installation assembly to solve problems such as poor installation adaptability, insufficient stability of steel structure connections, and low precision of component installation. Utility Model Content

[0017] Compared with the prior art, the present invention has the following advantages and technical effects:

[0018] 1. The factory facade wall-mounted photovoltaic installation assembly provided by this utility model uses two types of special base connectors: a base connector on the support arm and a base connector on the steel column. These are fixed to the connecting steel column of the factory facade and the connecting hardened ground, forming a "double load-bearing support point". The support arm laterally supports the steel column, and the steel column is rigidly connected to the main beam by T-shaped connectors and cross-shaped connectors, constructing a grid-like steel structure frame extending along the facade. This can transfer the self-weight of the photovoltaic modules and wind, solving the problem of traditional installation schemes that "only adapt to a single load-bearing structure and have weak frame load-bearing capacity". It enables the installation of complex load-bearing structures such as factory building steel columns and hardened ground, ensuring the long-term stable load-bearing of the main steel structure without the risk of deformation or loosening.

[0019] 2. The factory facade wall-mounted photovoltaic installation assembly provided by this utility model achieves precise connection and fine-tuning of the column, main beam, and crossbeam through corner brackets, forming a reference surface for component installation. The bracket supports the bottom and positions the ends of the photovoltaic module to avoid lateral displacement. The horizontal and vertical pressure plates press the horizontal and vertical splicing joints of the module respectively to prevent misalignment. The horizontal and vertical cover plates snap onto the pressure plates to seal the splicing seams, solving the problems of "easy component displacement and easy water ingress and corrosion in splicing seams" in traditional installation. This ensures that the photovoltaic module is installed flat and in a precise position, while isolating the splicing joints from rainwater and dust, and extending the service life of the photovoltaic module and connecting parts.

[0034] like Figures 1 to 11 As shown, this utility model provides a factory facade wall-mounted photovoltaic installation assembly, including a steel structure main body and a photovoltaic module installation structure;

[0035] The main steel structure includes a base connector 6 on the support arm, a base connector 8 on the steel column, a support arm 4, a steel column 2, and a main beam 1.

Anti-slip pads are provided on the contact surfaces of the corner bracket 10 with the column 11, the main beam 1 and the cross beam 12.

[0042] The design is further optimized so that the support 14 includes a connecting plate, on which a horizontal support plate and a vertical baffle are fixedly installed. The connecting plate is fixedly connected to the crossbeam 12. One side of the horizontal support plate is attached to the lower edge of the photovoltaic module 13, and the vertical baffle is perpendicularly connected to one end of the horizontal support plate.

[0043] Further optimizing the scheme, the photovoltaic module installation structure also includes a horizontal pressure plate 18, a vertical pressure plate 17, a horizontal cover plate 16, and a vertical cover plate 15; the horizontal pressure plate 18 covers the horizontal splicing of two adjacent photovoltaic modules 13, and the horizontal pressure plate 18 is fixedly connected to the crossbeam 12; the vertical pressure plate 17 covers the vertical splicing of two adjacent photovoltaic modules 13, and the vertical pressure plate 17 is fixedly connected to the crossbeam 12; the horizontal cover plate 16 covers the outside of the horizontal pressure plate 18, and the vertical cover plate 15 covers the outside of the vertical pressure plate 17.

[0044] The design is further optimized so that the length of the horizontal pressure plate 18 is adapted to the width of the photovoltaic module 13, and bolt holes are provided at both ends of the horizontal pressure plate 18. The horizontal pressure plate 18 is threadedly connected to the crossbeam 12 by bolts and pressed onto the photovoltaic module 13. The length of the vertical pressure plate 17 is adapted to the height of the photovoltaic module 13, and bolt holes are provided at both ends of the vertical pressure plate 17. The vertical pressure plate 17 is threadedly connected to the crossbeam 12 by bolts and pressed onto the photovoltaic module 13.

[0045] In a further optimized design, the inner side of the horizontal cover plate 16 is provided with a slot that matches the horizontal pressure plate 18, and the horizontal cover plate 16 is fixed to the horizontal pressure plate 18 by the slot; the inner side of the vertical cover plate 15 is provided with a slot that matches the vertical pressure plate 17, and the vertical cover plate 15 is fixed to the vertical pressure plate 17 by the slot.

[0046] The wall-mounted photovoltaic installation assembly for factory facades provided by this utility model has a base connector 6 on the support arm fixed to the connecting steel column 7 of the factory facade, and a base connector 8 on the steel column fixed to the connecting hardened ground 9, forming a dual load-bearing support point of "factory steel column-hardened ground"; one end of the support arm 4 is fixed to the connecting steel column 7, and the other end is fixed to the steel column 2, providing lateral support for the steel column 2; the steel columns 2 are arranged at intervals along the height of the factory facade, and adjacent steel columns 2 are fixed to the main beam 1 through T-shaped connectors 5 or cross-shaped connectors 3. The main beam 1 extends along the length of the facade, together forming a grid-like self-supporting frame to support the photovoltaic modules 13.

[0047] The columns 11 are fixed to the main beam 1 via angle brackets 10, and multiple columns 11 are arranged at intervals along the length of the main beam 1. The crossbeams 12 are vertically fixed to the columns 11 via angle brackets 10, forming a reference surface for module installation. The brackets 14 are fixed to the crossbeams 12, and the photovoltaic modules 13 are placed on the brackets 14 for bottom positioning. The horizontal pressure plate 18 covers the horizontal splice of adjacent photovoltaic modules 13, and the vertical pressure plate 17 covers the vertical splice of adjacent photovoltaic modules 13, and both are fixed to the crossbeams 12 to press the photovoltaic modules 13 tightly. The horizontal cover plate 16 covers the horizontal pressure plate 18, and the vertical cover plate 15 covers the vertical pressure plate 17, completing the splice protection. This allows for the compatible installation of steel columns and hardened ground in the complex load-bearing structure of the factory facade, constructing a stable self-supporting steel structure frame, while simultaneously achieving precise positioning, fixing, and splice seam protection for the photovoltaic modules, solving the problems of "poor adaptability, unstable load-bearing capacity, and easy module displacement" in traditional installation schemes.

[0048] The open end of the steel column base connector 8 engages with the outer periphery of the steel column 2, initially positioning the steel column base connector 8 and the steel column 2. Bolts are then inserted through the corresponding holes in the steel column base connector 8 and the steel column 2 and tightened to rigidly fix the steel column 2 to the steel column base connector 8, preventing the steel column 2 from shifting along the opening direction of the steel column base connector 8. Similarly, the open end of the support arm base connector 6 engages with the outer periphery of the support arm 4 and is similarly tightened with bolts, ensuring a secure connection between the support arm 4 and the support arm base connector 6, preventing the support arm 4 from detaching from the support arm base connector 6 when transmitting loads. Through this dual fixing method of "engaging positioning and bolt tightening," the stable connection between the steel column base connector 8 and the steel column 2, and between the support arm base connector 6 and the support arm 4, prevents the base from loosening with its corresponding components, improving the load-bearing reliability of the main steel structure.

[0049] A rigid connection node between steel column 2 and main beam 1 is constructed using T-shaped connector 5 and cross-shaped connector 3: The vertical ends of the T-shaped connector 5 are respectively attached to two adjacent steel columns 2, and bolts are passed through the bolt holes in the vertical section and tightened. The horizontal section is attached to the side wall of the main beam 1 and is also fixed with bolts, allowing the load of the main beam 1 to be transferred from the horizontal section to the vertical section, and then to the steel column 2. The horizontal ends of the cross-shaped connector 3 are respectively fixed to two adjacent main beams 1 with bolts, and the vertical ends of the cross-shaped connector 3 are respectively fixed to two adjacent steel columns 2 with bolts, forming a two-way load transfer path of "main beam-connector-steel column". Both types of connectors are fastened with bolts to ensure a gapless connection node.

[0050] Of the four connecting ends of the corner bracket 10, two adjacent ends are attached to the side wall of the column 11 and fastened with bolts; the other two adjacent ends are attached to the side wall of the main beam 1 or the crossbeam 12 and fixed with bolts in the same way, so that the column 11 and the main beam 1, and the column 11 and the crossbeam 12 form a vertical and precise connection relationship. The contact surfaces of the corner bracket 10 with the column 11, the main beam 1 and the crossbeam 12 are all equipped with anti-slip pads. The pads increase the friction of the contact surfaces and prevent the bolts from loosening and the parts from shifting due to the low-frequency vibration generated by the operation of the factory equipment.

[0051] The upper surface of the horizontal support plate of the bracket 14 is attached to the lower edge of the photovoltaic module 13 to provide vertical support for the module. The bracket 14 is fixed to the crossbeam 12 by welding or bolting, transferring the weight of the module to the crossbeam 12. The vertical baffle of the bracket 14 is perpendicularly connected to the horizontal support plate, and the side wall of the vertical baffle is attached to the end of the photovoltaic module 13 to limit the lateral displacement of the module along the length of the crossbeam 12. The spacing between adjacent brackets 14 is adapted to the width of the photovoltaic module 13 to ensure that each module is supported by at least two sets of brackets 14.

[0052] The length of the horizontal pressure plate 18 is adapted to the width of the photovoltaic module 13, covering the horizontal joint of two adjacent photovoltaic modules 13. The bolt holes at both ends of the horizontal pressure plate 18 are aligned with the threaded holes of the crossbeam 12. After the bolts pass through the holes, they are tightened to press the horizontal pressure plate 18 onto the frame of the photovoltaic module 13, restricting the vertical displacement of the photovoltaic module 13. The length of the vertical pressure plate 17 is adapted to the height of the photovoltaic module 13, covering the vertical joint of adjacent photovoltaic modules 13. Similarly, it is fixed to the crossbeam 12 with bolts and presses the photovoltaic module 13, restricting the horizontal displacement of the photovoltaic module 13.

[0053] The transverse cover 16 is fitted to the outer periphery of the transverse pressure plate 18 via a groove on its inner side, ensuring a tight fit between the inner wall of the groove and the transverse pressure plate 18. The vertical cover 15 is fitted to the outer side of the vertical pressure plate 17, preventing rainwater and dust from entering the component splice seam. The covers are made of corrosion-resistant metal to prevent corrosion of the pressure plate and component frame by corrosive gases and rainwater in the factory environment, thus extending the service life of the connecting components.

[0054] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of protection of this utility model.
