Description

Technical Field

[0001] This utility model relates to the field of guide rail technology, specifically to a guide rail for a photovoltaic support with adjustable load-bearing area. Background Technology

[0002] Guide rails are a key component in photovoltaic mounting systems used to support and fix solar panels. They facilitate the quick splicing and assembly of photovoltaic mounting systems and allow for easy adjustment of the position and angle of the mounting systems later, thereby reducing production and installation costs.

[0003] Existing guide rails are generally fixed installations, thus only accommodating guide rails and solar panels of specified dimensions. When it is necessary to increase the area of ​​the solar panel or the size of the bracket, the guide rail is not convenient to quickly adjust its size, exhibiting weak adaptability and certain limitations. Therefore, a new technical solution is needed to address this issue. Summary of the Invention

[0004] The purpose of this utility model is to provide a guide rail for a photovoltaic bracket with adjustable bearing area, which solves the problem mentioned in the background art that the existing guide rails are generally fixed and can only adapt to guide rails and solar panels of a specified size. When it is necessary to increase the area of ​​the solar panel and the size of the bracket, the guide rail is not convenient to quickly adjust the size and has weak adaptability.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a guide rail for a photovoltaic support with adjustable bearing area, comprising a main guide rail, an X-shaped frame, and a secondary guide rail. A protrusion is fixedly connected to the side wall of the main guide rail, and a positioning rod is rotatably connected to the bottom surface of the protrusion. A plurality of equidistant positioning holes are opened on the surface of the positioning rod. Side strips are fixedly connected to the front and rear side walls of the main guide rail and the secondary guide rail. A plurality of equidistant screw holes are opened on the surface of the side strips. The four ends of the X-shaped frame are detachably connected to the side strips through screw holes and corresponding bolts.

[0006] In this technical solution, the secondary guide rail slides along the positioning rod, thereby changing the distance between it and the primary guide rail. It remains parallel to the primary guide rail throughout the sliding process, eliminating the need for subsequent positioning and calibration. The secondary guide rail allows the device to adapt to photovoltaic brackets and solar panels of different sizes, facilitating an increase in the load-bearing area of ​​the solar panels. The X-shaped frame supports both the primary and secondary guide rails. After the secondary guide rail is adjusted, the four ends of the X-shaped frame are secured with bolts through suitable screw holes on both sides, thus fixing and connecting the primary and secondary guide rails. This further improves their stability and enhances the overall structure's resistance to deformation.

[0007] Preferably, both the main guide rail and the secondary guide rail have slots at their bottoms, and the width of the slots is the same as the width of the positioning rod.

[0008] Preferably, slots and inserts are provided at both ends of the main guide rail and the secondary guide rail, and the diameter of the slot is the same as the diameter of the insert.

[0009] Preferably, the surfaces of the main guide rail and the secondary guide rail directly above the slot are provided with mounting holes, and the inner diameter of the mounting holes is the same as that of the positioning holes.

[0010] Preferably, the X-shaped frame is equipped with an angle adjustment structure, the height of which is lower than the top surfaces of the main guide rail and the secondary guide rail.

[0011] Preferably, the surface of the protrusion and the surface of the positioning rod directly below it are provided with fixing holes, the positioning rod is perpendicular to the secondary guide rail, and the main guide rail and the secondary guide rail are parallel to each other.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting a positioning rod and a secondary guide rail, allows the secondary guide rail to slide along the positioning rod, thereby changing the distance between it and the main guide rail. During the sliding process, it always remains parallel to the main guide rail, eliminating the need for subsequent special positioning calibration. The secondary guide rail enables the device to adapt to photovoltaic brackets and solar panels of different sizes, facilitating an increase in the load-bearing area of ​​the solar panels and improving the practicality of the device.

[0014] 2. This utility model uses an X-shaped frame to support the main guide rail and the secondary guide rail. After the secondary guide rail is adjusted to the desired position, the four ends of the X-shaped frame are fixed with bolts through suitable screw holes on both sides of the side strips. This fixes and connects the main guide rail and the secondary guide rail, further improving their stability and enhancing the overall structure's resistance to deformation.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description will further elaborate on them in conjunction with specific embodiments.

[0021] A guide rail for a photovoltaic support with adjustable load-bearing area, see [link / reference]. Figures 1 to 3 It includes a main guide rail 1, an X-shaped frame 9 and a secondary guide rail 2. A protrusion 101 is fixedly connected to the side wall of the main guide rail 1. A positioning rod 3 is rotatably connected to the bottom surface of the protrusion 101. A number of equidistant positioning holes 302 are opened on the surface of the positioning rod 3. Side strips 8 are fixedly connected to the front and rear side walls of the main guide rail 1 and the secondary guide rail 2. A number of equidistant screw holes 801 are opened on the surface of the side strips 8. The four edges of the X-shaped frame 9 are detachably connected to the side strips 8 through the screw holes 801 and the corresponding bolts.

[0022] Specifically, such as Figure 2 As shown, both the main guide rail 1 and the secondary guide rail 2 have slots 4 at their bottoms. When necessary, the main guide rail 1 can also be spliced ​​with other main guide rails 1 through its own slots 4. The width of the slots 4 is the same as the width of the positioning rod 3. Therefore, during the sliding process of the secondary guide rail 2, the positioning rod 3 and the slots 4 are tightly fitted and will not wobble, thus improving the stability during the sliding process.

[0023] It is worth noting that, such as Figure 3 As shown, slots 6 and rods 7 are provided at both ends of the main guide rail 1 and the secondary guide rail 2. The diameter of the slots 6 is the same as the diameter of the rods 7. When the main guide rail 1 and the secondary guide rail 2 are extended laterally, they are extended by splicing the slots 6 and the rods 7 to meet the splicing requirements of multiple photovoltaic brackets and solar panels.

[0024] It is worth noting that, such as Figure 1 As shown, mounting holes 5 are provided on the surfaces of the main guide rail 1 and the secondary guide rail 2 directly above the slot 4. The inner diameter of the mounting holes 5 is the same as that of the positioning holes 302. When the secondary guide rail 2 slides along the positioning rod 3, the mounting holes 5 and the positioning holes 302 are aligned, and bolts of the corresponding size can be screwed in to fix the secondary guide rail 2 in the current position and keep it stable.

[0025] It is worth noting that, such as Figure 2 As shown, the X-shaped frame 9 is equipped with an angle adjustment structure 10. The lead screw in the angle adjustment structure 10 changes the cross angle of the X-shaped frame 9 during the torsion process, thereby adapting to different spacings between the main guide rail 1 and the secondary guide rail 2. The height of the angle adjustment structure 10 is lower than the top surface of the main guide rail 1 and the secondary guide rail 2, thus avoiding obstruction of the sliding of the photovoltaic bracket and solar panel above.

[0026] It is worth noting that, such as Figure 1 and Figure 2As shown, fixing holes 301 are provided on the surface of the protrusion 101 and the surface of the positioning rod 3 directly below it. The positioning rod 3 is perpendicular to the secondary guide rail 2, and the main guide rail 1 and the secondary guide rail 2 are parallel to each other.

[0027] Working Principle: When adjusting the load-bearing area of ​​the photovoltaic support, the operator first loosens the bolts securing the positioning rod 3, allowing the secondary guide rail 2 to slide along the positioning rod 3, which is rotatably connected to the protrusion 101 on the side wall of the main guide rail 1. The positioning rod 3 has equidistant positioning holes 302 on its surface. The slot 4 at the bottom of the secondary guide rail 2 fits tightly with the positioning rod 3, ensuring that the secondary guide rail 2 remains parallel to the main guide rail 1 during sliding, preventing offset. When the secondary guide rail 2 moves to the target position, it aligns with the positioning hole 302 through the mounting hole 5, and a bolt is inserted to lock it in place, achieving precise spacing adjustment. After adjustment, the X-frame 9 connects the main guide rail 1 and the secondary guide rail 2 through the screw holes 801 of the side strip 8. The angle adjustment structure 10 of the X-frame 9 changes the cross angle via a lead screw, adapting to different support requirements at different spacings and enhancing the overall structure's resistance to deformation. When the guide rail length needs to be extended laterally, the insertion rods 7 at both ends of the main guide rail 1 and the secondary guide rail 2 are inserted into the slots 6 of the adjacent guide rails, forming a continuous load-bearing surface to meet the splicing requirements of large-size photovoltaic modules.

[0028] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.

[0029] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
