Description

Technical Field

[0001] This utility model relates to the field of photovoltaic installation, and in particular to a height-adjustable photovoltaic bracket. Background Technology

[0002] At photovoltaic project construction sites, some areas have poor flatness. The photovoltaic brackets and cement supports used are mostly standard design components, which are difficult to adapt to uneven site conditions, easily leading to the photovoltaic modules failing to meet acceptance standards after installation. According to GB 50794-2012 "Construction Specifications for Photovoltaic Power Stations," the tilt angle deviation of photovoltaic modules should not exceed 1°, the edge height difference between adjacent photovoltaic modules should not exceed 2mm, and the edge height difference between photovoltaic modules in the same group should not exceed 5mm. Uneven ground significantly affects the installation angle and the height difference between modules, even causing some cement supports to be suspended, posing structural safety hazards to the later operation of the power station and affecting the reliability of the system's power generation. The traditional solution is to level the construction site over a large area, but this method increases project investment, extends the construction period, and may damage the original building structure or add additional loads during construction.

[0003] Therefore, those skilled in the art are dedicated to developing a highly adjustable photovoltaic bracket that is easy to operate, widely adaptable, and inexpensive to manufacture. Utility Model Content

[0012] Preferably, a first locking bolt is detachably installed in the first strip hole, and the end of the first locking bolt passes through the first strip hole and the fixing lock hole in sequence and extends out of the fixing lock hole.

[0013] Preferably, the seventh connecting segment is provided with a second strip-shaped hole, and a second locking bolt is detachably installed in the second strip-shaped hole, and the second locking bolt can slide freely along the second strip-shaped hole.

[0015] The beneficial effects of this utility model are as follows: This utility model allows for flexible adjustment of the combined height of the lower and upper supports within the design range, thereby ensuring that photovoltaic module installation meets acceptance standards even on uneven ground, significantly reducing the manpower, material resources, and time costs associated with ground leveling.

[0022] like Figure 1-5 As shown, a height-adjustable photovoltaic (PV) support includes a lower support 1, with an upper support 2 slidably fitted onto the lower support 1. The top of the upper support 2 is bent to form a load-bearing platform for mounting PV modules (not shown in the figure). In practical applications, the lower support 1 and upper support 2 are typically made of high-strength steel to ensure the overall structure possesses the necessary mechanical strength and long-term durability. Further, the lower support 1 includes a base 11, which serves as the mounting foundation and comprises a first connecting segment 11a, a second connecting segment 11b, a third connecting segment 11c, a fourth connecting segment 11d, and a fifth connecting segment 11e connected sequentially. The second connecting segment 11b and the fourth connecting segment 11d are inclined. Specifically, a first included angle α is formed between the first connecting segment 11a and the second connecting segment 11b, and a second included angle β is formed between the fourth connecting segment 11d and the fifth connecting segment 11e. The first included angle α and the second included angle β are equal, and 110°≤α≤130°. The first connecting segment 11a, the second connecting segment 11b, the third connecting segment 11c, the fourth connecting segment 11d, and the fifth connecting segment 11e, together with the mounting reference surface (not shown in the figure), form a geometrically closed structure (specifically, it can be presented as a "trapezoidal" or "V-shaped" shape). This structure transforms the load it receives into internal axial stress through its overall geometric shape, and through the cooperative force transmission mechanism of each connecting segment, it achieves uniform force distribution and structural stability of the support system. Furthermore, a vertically extending vertical plate 13 is fixedly connected to the top of the base 11. The vertical plate 13 has a fixing locking hole 131, which provides a precise positioning and installation foundation for the subsequent first locking bolt 211a.

[0023] In this embodiment, the first connecting segment 11a and the fifth connecting segment 11e are each provided with two self-tapping screw holes 12. The two self-tapping screw holes 12 are spaced apart. The self-tapping screw holes 12 provide a threaded installation path and fix the base 11. In other embodiments, other numbers of self-tapping screw holes 12 can be provided according to actual needs.

[0024] like Figure 2As shown, the upper support 2 includes a sixth connecting section 21 and a seventh connecting section 22, which are vertically connected and together form a bent structure, providing an installation base for the photovoltaic module (not shown in the figure). Specifically, the sixth connecting section 21 is provided with a first strip hole 211 that cooperates with the fixing lock hole 131. The first strip hole 211 completely penetrates the sixth connecting section 21, and a first locking bolt 211a is detachably installed inside it. The end of the first locking bolt 211a passes through the first strip hole 211 and the fixing lock hole 131 in sequence and extends out of the fixing lock hole 131. The first locking bolt 211a can slide freely along the first strip hole 211, and the lower support 1 and the upper support 2 are locked in a timely manner by setting the first locking bolt 211a. Furthermore, the seventh connecting section 22 is provided with a second strip-shaped hole 221, in which a second locking bolt 221a is detachably installed. The second locking bolt 221a can slide freely along the second strip-shaped hole 221, and the upper bracket 2 and photovoltaic module (not shown in the figure) are locked in a timely manner by setting the second locking bolt 221a. Even further, the first locking bolt 211a and the second locking bolt 221a adopt the same structural design, both including a smooth section (not shown in the figure) and a threaded section (not shown in the figure). The length of the smooth section is greater than or equal to the total thickness of the vertical plate 13 and the sixth connecting section 21 after stacking, so that the smooth surface of the screw bears the main shear force and avoids direct compressive stress between the threaded part and the connecting parts. This effectively prevents bracket deformation caused by stress concentration when applying tightening torque, improving the stability and installation reliability of the bracket structure. In use, firstly, several lower brackets 1 are fixed to the installation reference surface, using methods such as bolting or welding. After the lower brackets 1 are installed, the upper bracket 2 is slid to adjust its relative position to the lower brackets 1 according to actual site requirements, until the bearing platform at the top of the upper bracket 2 reaches the predetermined installation height and level. Then, the first locking bolt 211a is tightened to lock the upper bracket 2 and lower brackets 1 together, forming a stable main support structure. Finally, the photovoltaic modules are installed on the upper bracket 2 and locked with the second locking bolt 221a to complete the overall installation.

[0025] This application allows for flexible adjustment of the combined height of the lower support 1 and the upper support 2 within the design scope, enabling photovoltaic module installation to meet acceptance standards even on uneven sites, significantly reducing the manpower, material, and time costs associated with ground leveling. Simultaneously, the sliding connection design of the lower support 1 and the upper support 2 effectively improves the overall flatness of the photovoltaic module installation, enhancing the adaptability and engineering practicality of the support system.
