Description

Technical Field

[0001] This utility model relates to the technical field of solar module installation, and in particular to a vertical mounting fixture structure for photovoltaic solar modules. Background Technology

[0002] Photovoltaic power generation technology converts light energy into electrical energy, making full use of nature's energy. Currently, solar modules are all bifacial, absorbing sunlight on both sides and converting it into electricity. However, traditional installation methods use an angled installation, which results in low utilization due to single-sided power generation. The current solution is to install the modules at a 90° angle perpendicular to the ground. This method allows power generation from both sides of the module. The mainstream vertical installation method uses screws and clamps to connect the frame to the bracket. Existing installation methods have significant limitations for vertical installation. Vertical installation increases the windward area of ​​the module, leading to increased positive and negative pressure. Traditional bolts and conventional clamps cannot meet the requirements of vertical installation. Specifically, traditional bolt installation is prone to torque dependence, stress deformation of the solar module frame, insufficient shear resistance leading to frame breakage, and tearing of mounting holes under high back pressure. Traditional clamp installation, on the other hand, is prone to internal stress concentration leading to material fatigue, limited module spacing adjustment, and insufficient wind load resistance. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by providing a vertical mounting fixture structure for photovoltaic solar modules. This structure ensures uniform and reliable pressure is applied to the frame of the solar module under various environmental conditions, preventing frame displacement or loosening and effectively enhancing the overall stability of the solar module. Furthermore, the entire module mounting structure provides a flexible and stable connection method, forming a tight and stable interlocking connection, further improving the anti-slip and anti-vibration performance of the module connection parts, and effectively coping with complex and variable outdoor conditions such as wind and vibration.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows: a vertical mounting fixture structure for photovoltaic solar modules, comprising an upper pressure block, an inner pressure block, and a bolt assembly; the upper pressure block has a C-shaped cross-section, and an mounting position for covering the frame of the photovoltaic solar module is formed on the inner side of the upper pressure block; a C-shaped groove is provided on the side of the bottom end of the upper pressure block; a through hole is provided on the upper pressure block and the through hole vertically penetrates the C-shaped groove; a first serrated structure is provided on the bottom end face of the C-shaped groove; a groove is provided on one side of the inner pressure block; an oblong hole is provided on the inner pressure block and the oblong hole vertically penetrates the groove and corresponds to the through hole of the upper pressure block; a second serrated structure matching the first serrated structure is provided on the bottom surface of the inner pressure block; the bottom end of the inner pressure block extends into the C-shaped groove of the upper pressure block; the first serrated structure and the second serrated structure mesh; the bolt assembly can pass through the oblong hole of the inner pressure block and the through hole of the upper pressure block; the upper pressure block and the inner pressure block are connected as a whole by the bolt assembly.

[0005] Furthermore, the bolt assembly includes a bolt, a washer, and a nut; the bolt end of the bolt passes through the waist-shaped hole of the inner pressure fixture and the through hole of the upper pressure block, and the bolt end of the bolt extends outward from the upper pressure block, and is sequentially equipped with a washer and a nut, and a washer is also provided between the nut end of the bolt and the inner pressure fixture.

[0006] Furthermore, the bolt is an M8 bolt.

[0007] Furthermore, the cross-section of the inner pressure fixture has a C-shaped structure.

[0008] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0009] This invention improves the traditional photovoltaic solar module installation structure. While achieving a 90° vertical installation angle between the photovoltaic solar module and the ground, it uses an upper pressure block and an inner pressure block combined with M8 bolts for installation. This minimizes the stress on the photovoltaic solar module frame, prevents the frame material from breaking, and completely covers three sides of the photovoltaic solar module frame. Under high wind pressure, the photovoltaic solar module frame experiences less stress, protecting it from deformation and providing strong wind pressure resistance. It also eliminates the risk of damage to the photovoltaic solar module due to frame breakage. Attached Figure Description
