Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic module installation technology, and in particular relates to a composite guide rail for fixing photovoltaic modules. Background Technology

[0002] With the popularization of distributed photovoltaic (PV) power generation technology, fixing PV modules to corrugated steel roofs has become an important way to achieve green energy conversion. In this installation scenario, the guide rail, as a key component connecting the PV modules to the roof, directly affects the safety and stability of the PV system.

[0003] Currently, the most commonly used photovoltaic module mounting rails on the market mainly include H-type rails (as shown in the attached diagram in the instruction manual). Figure 5 ) and ribbed guide rails (as shown in the attached diagram of the instruction manual) Figure 6 H-type guide rails are widely used due to their simple structural design and cost-effectiveness; ribbed guide rails, on the other hand, effectively improve structural strength and wind resistance by adding reinforcing ribs, making them suitable for projects with high stability requirements.

[0004] However, both types of guide rails have significant shortcomings: H-type guide rails lack effective reinforcement measures and are not strong enough to resist wind damage in extreme weather conditions such as strong winds. The parts that fix photovoltaic modules are prone to deformation, which can cause the modules to loosen or even fall off. Although ribbed guide rails can meet the high strength requirements, the added reinforcing ribs and other components lead to a significant increase in material consumption, which not only increases processing costs but also increases the overall structural weight, limiting their application in more scenarios.

[0005] Therefore, it is essential to invent a composite guide rail for fixing photovoltaic modules. Utility Model Content

[0006] To address the above problems, this utility model proposes a composite guide rail for fixing photovoltaic modules, and the technical solution used is as follows:

[0007] A composite guide rail for fixing photovoltaic modules includes a partition, side plates, a fixing frame, and stiffeners. Side plates are fixed to both sides of the partition by welding, and the two side plates are arranged in a mirror image. A fixing frame is fixed to the upper ends of the side plates by welding, and a stiffener is fixed to the lower side of the fixing frame by welding. The lower side of the stiffener is fixed to the upper side of the partition by welding.

[0008] Furthermore, the side plate includes a plate body, a lower positioning plate, and an upper positioning plate. The lower end of the plate body is fixed with the lower positioning plate by welding, and the upper side of the plate body is fixed with the upper positioning plate by welding. The lower side of the upper positioning plate is fixed with a fixing frame by welding. With this arrangement, the upper positioning plate can fix the fixing frame, and the lower positioning plate facilitates fixing the composite guide rail to the color steel tile roof by fixing components.

[0009] Furthermore, the lower positioning plate has several grooves on its lower side, which are arranged in parallel. The grooves can improve the friction between the lower positioning plate and the corrugated steel roof.

[0010] Furthermore, the stiffeners are respectively perpendicular to the upper side of the partition and the lower side of the fixing frame. This arrangement can prevent the fixing frame from deforming when subjected to external wind force, thus avoiding affecting the fixing effect on the photovoltaic module.

[0011] Furthermore, the upper side of the fixing frame is provided with a cross-shaped groove. This design facilitates the fixing of the photovoltaic module to the fixing frame by the cooperation of the stud and nut in the fixing component.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The ribs in this invention reinforce the position of the mounting bracket, increasing its bending stiffness by 42% (compared to H-type guide rails). This prevents the mounting bracket from deforming under external wind forces, thus avoiding any impact on the fixation of the photovoltaic modules. Furthermore, the lower end of the side plate of this invention retains the symmetrical flange structure of the standard H-type guide rail. The double flange design can distribute the dynamic load of the corrugated steel roof while maintaining compatibility with existing H-type guide rail installation accessories. In addition, the material usage is reduced by 18-22% compared to ribbed guide rails. Attached Figure Description

[0025] Please see Figures 1 to 6 As shown, this utility model is a composite guide rail for fixing photovoltaic modules, including a partition plate 1, side plates 2, a fixing frame 3 and a stiffener 4. The two sides of the partition plate 1 are fixed with side plates 2 by welding, and the two side plates 2 are arranged in a mirror image. The upper ends of the side plates 2 are fixed with the fixing frame 3 by welding, and the lower side of the fixing frame 3 is fixed with the stiffener 4 by welding. The lower side of the stiffener 4 is fixed to the upper side of the partition plate 1 by welding.

[0026] Furthermore, the side plate 2 includes a plate body 21, a lower positioning plate 22 and an upper positioning plate 23. The lower end of the plate body 21 is fixed with the lower positioning plate 22 by welding, and the upper side of the plate body 21 is fixed with the upper positioning plate 23 by welding. The lower side of the upper positioning plate 23 is fixed with a fixing frame 3 by welding. With this arrangement, the upper positioning plate 22 can fix the fixing frame 3, and the lower positioning plate 23 is set to facilitate the fixing of the composite guide rail to the color steel tile roof (6) by fixing components.

[0027] Furthermore, the lower side of the lower positioning plate 22 is provided with several grooves 24, which are arranged in parallel. The grooves 24 can increase the friction between the lower positioning plate 23 and the color steel tile roof 6, thereby preventing the composite guide rail from sliding on the color steel tile roof 6.

[0028] Furthermore, the stiffening plate 4 is set perpendicularly to the upper side of the partition plate 1 and the lower side of the fixing frame 3 respectively. With this arrangement, the stiffening plate 4 can reinforce the position of the fixing frame 3, thereby preventing the fixing frame 3 from deforming when subjected to external wind force, which would affect the fixing effect of the photovoltaic module 5.

[0029] Furthermore, a cross-shaped groove is provided on the upper side of the fixing frame 3. This design allows the nut of the fixing component to be slidably placed inside the cross-shaped groove. Then, the photovoltaic module 5 is fixed to the fixing frame 3 by the cooperation of the stud and the nut in the fixing component.

[0030] Please see Figure 1-6 As shown, this utility model is a composite guide rail for fixing photovoltaic modules. Its working principle is as follows: when it is necessary to fix the photovoltaic module 5 to the color steel tile roof 6, the guide rail is first fixed to the color steel tile roof 6 by the cooperation of the fixing component and the lower positioning plate 22, and then the photovoltaic module 6 is fixed on the fixing frame 3 by the fixing component.
