Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, and in particular to a photovoltaic support with adjustable size. Background Technology

[0002] Solar photovoltaic (PV) brackets are specialized supports designed for placing, installing, and securing solar panels in a solar photovoltaic power generation system. They are typically made of aluminum alloy, carbon steel, or stainless steel. Solar support system products are made of carbon steel and stainless steel; the carbon steel surface is hot-dip galvanized, ensuring it will not rust for 30 years of outdoor use.

[0003] To ensure sufficient solar energy supply to photovoltaic (PV) power generation equipment, technicians need to fix the PV panels onto PV mounting systems. However, traditional PV mounting systems lack size adjustment capabilities. When the size and specifications of the PV panels change, workers need to perform secondary processing or re-customization of the mounting systems on-site, thus reducing the assembly efficiency of the PV power generation equipment. Furthermore, since PV panels and mounting systems are typically connected in a fixed manner to ensure connection stability, this fixed connection creates a space for rainwater to accumulate in the gap between the mounting system and the PV panels. This rainwater cannot be properly drained, and point support methods cannot provide perfect stabilization for the PV panels. Therefore, we propose a size-adjustable PV mounting system. Utility Model Content

[0004] This utility model addresses the problems of photovoltaic brackets lacking size adjustment functions and the gap between the bracket and the photovoltaic panel creating a space for rainwater storage, which prevents proper drainage. It provides a size-adjustable photovoltaic bracket that is easy to install, has a simplified structure, and good waterproof performance.

[0005] This utility model provides the following technical solution: a photovoltaic bracket with adjustable size, including a support frame, the support frame including multiple horizontally arranged angle steels, and multiple connecting components for connecting adjacent photovoltaic panels on the left and right sides are detachably installed on the angle steels. The connecting components include a box, clamping plates, connecting rods and clamping springs. The clamping plates are symmetrically arranged on the left and right sides of the box, and the openings of the clamping plates are arranged outwards. The clamping springs are located inside the box. One end of the connecting rod is connected to the inner wall of the clamping plate, and the other end of the connecting rod extends into the box and is connected to the clamping spring. The clamping side wall of the clamping plate is provided with a guide strip.

[0006] In some embodiments, a track for placing photovoltaic panels is formed between two adjacent angle steels.

[0007] In some embodiments, the angle steel is provided with a plurality of mounting holes arranged at equal intervals, and the box body is provided with a connecting hole that mates with the mounting holes. The connecting hole and the mounting hole are connected by bolts, and a locking nut is provided at the bottom of the bolt for locking.

[0008] In some embodiments, the connecting rod is provided with a threaded portion, and a limiting nut that mates with the threaded portion is sleeved on the connecting rod. The limiting nut is located on the outside of the housing.

[0009] In some embodiments, the inner end of the connecting rod is connected to the clamping spring via a limiting plate.

[0010] In some embodiments, multiple sets of clamping springs that are always in a compressed state are provided between the limiting plates.

[0011] In some embodiments, there are two guide strips on a single clamp plate, with the two guide strips arranged one above the other.

[0012] In some embodiments, the support frame adopts a prism frame structure with a right-angled triangle cross section, the top surface of which corresponds to the hypotenuse of the right-angled triangle, and the photovoltaic panel forms a slope when it is installed in the support frame.

[0013] Compared with the prior art, the advantages of this utility model are:

[0014] 1. Flexible size adjustment, strong adaptability, and adjustable lateral spacing: The angle steel is equipped with equally spaced mounting holes, and the connecting components are connected to the mounting holes by bolts. The spacing between adjacent connecting components can be flexibly adjusted according to the actual size of the photovoltaic panel, adapting to photovoltaic panels of different specifications, improving the versatility of the bracket, and reducing customization costs.

[0015] 2. Stable structure with excellent wind and earthquake resistance, combining elastic clamping with rigid support: The clamping spring provides continuous clamping force, ensuring that the edge of the photovoltaic panel is stably clamped. At the same time, the design of the limit nut and multiple sets of compressed springs ensures that the clamping plate always maintains pressure on the photovoltaic panel under vibration or wind, reducing the risk of loosening.

[0016] III. Flow-guiding protrusions enhance module lifespan: Two flow-guiding protrusions, one above the other, on the clamping surface of the clamping plate guide rainwater and dust out along the gaps between the protrusions, preventing water and dust accumulation at the edges of the photovoltaic panel, reducing corrosion and shading, improving power generation efficiency, and lowering the frequency of cleaning and maintenance. Simultaneously, they form two independent flow-guiding gaps; even if one gap is obstructed by debris or localized water accumulation, the other can still maintain its drainage function, significantly improving drainage reliability. The vertical distribution design disperses the gravitational potential energy of rainwater onto two flow paths, avoiding water impact or splashing caused by concentrated drainage at a single point. Especially during heavy rain, the dual channels can more efficiently guide water flow quickly and rapidly along the inclined surface of the photovoltaic panel. The two protrusions form multi-point contact, increasing the contact area between the clamping plate and the edge of the photovoltaic panel compared to a single protrusion design. This reduces the risk of photovoltaic panel displacement under vibration or wind load conditions, while also preventing stress concentration at the edges of the photovoltaic panel due to excessive clamping.

[0031] The technical solutions provided by the various embodiments of this application are described below with reference to the accompanying drawings.

[0032] Please see Figure 1-6As shown in this embodiment: a photovoltaic bracket with adjustable size includes a support frame 1. The support frame 1 includes multiple horizontally arranged angle steels 5. Multiple connecting components 2 for connecting adjacent photovoltaic panels 4 are detachably installed on the angle steels 5. The connecting components 2 include a box body 21, clamping plates 22, connecting rods 23 and clamping springs 24. The clamping plates 22 are symmetrically arranged on the left and right sides of the box body 21, and the openings of the clamping plates 22 face outward. The clamping springs 24 are located inside the box body 21. One end of the connecting rod 23 is connected to the inner wall of the clamping plate 22, and the other end of the connecting rod 23 extends into the box body 21 and is connected to the clamping spring 24. The clamping side wall of the clamping plate 22 is provided with a guide strip 3.

[0033] In some embodiments, such as Figure 4 As shown, a track 51 for placing the photovoltaic panel 4 is formed between two adjacent angle steels 5. It should be noted that the photovoltaic panel 4 is mounted on the track 51 of the angle steel 5 to support the photovoltaic panel 4.

[0034] In some embodiments, such as Figures 4-7 As shown, the angle steel 5 is provided with multiple mounting holes 52 arranged at equal intervals, and the box body 21 is provided with connecting holes 211 that mate with the mounting holes 52. The connecting holes 211 and the mounting holes 52 are connected by bolts 25. The bottom of the bolts 25 is provided with locking nuts 26 for locking. It should be noted that by selecting different positions of the mounting holes 52 on the angle steel 5, the lateral position of the connecting component 2 on the angle steel 5 can be changed, thereby adjusting the spacing between adjacent photovoltaic panels 4 and adapting to photovoltaic panels 4 of different sizes. The bolt 25 connection facilitates quick on-site installation, disassembly and replacement of components. Especially when the photovoltaic panel 4 needs to be repaired or replaced, there is no need to disassemble the entire bracket, which improves maintenance efficiency.

[0035] It should be noted that the connecting holes 211 are respectively located at both ends of the contract, and both ends of the box body 21 are connected to the mounting holes 52 of the angle steel 5 by bolts 25.

[0036] It should be noted that the box body 21 includes an upper cover 213 and a bottom box 212. The upper cover 213 is snapped onto the bottom box 212 and can be removed from the bottom box 212.

[0037] In some embodiments, such as Figures 5-6 As shown, the connecting rod 23 is provided with a threaded part 231, and a limiting nut 27 that mates with the threaded part 231 is sleeved on the connecting rod 23. The limiting nut 27 is located on the outside of the box 21. It should be noted that the clamping spring 24 provides a continuous clamping force, so that the edge of the photovoltaic panel 4 is stably clamped. The design of multiple compressed springs provides flexible support, and the limiting nut 27 provides rigid support. By rotating the limiting nut 27, the extension length of the connecting rod 23 can be adjusted to ensure that the clamping plate 22 always maintains pressure on the photovoltaic panel 4 under vibration or wind, reducing the risk of loosening.

[0038] In some embodiments, such as Figures 5-6 As shown, the inner end of the connecting rod 23 is connected to the clamping spring 24 through the limiting plate 28. It should be noted that the limiting plate 28 increases the contact area between the spring and the connecting rod 23, so that the spring force is evenly transmitted to the clamping plate 22 through the connecting rod 23, avoiding the clamping plate 22 tilting or local stress concentration caused by single-point force. The limiting plate 28 restricts the radial displacement of the spring during the compression process, preventing the spring from twisting or detaching from the connecting rod 23, ensuring that the clamping force direction is always perpendicular to the frame of the photovoltaic panel 4, improving the fixing accuracy. The limiting plate 28 provides an installation reference for the spring, which is convenient for accurate assembly during factory prefabrication and reduces on-site installation errors.

[0039] In some embodiments, such as Figure 5 As shown, multiple sets of clamping springs 24 that are always in a compressed state are provided between the limiting plates 28. It should be noted that the multiple sets of clamping springs 24 can provide greater support for the clamping plate 22.

[0040] In some embodiments, such as Figures 2-3 As shown, there are two guide strips 3 on the single clamping plate 22, arranged one above the other. It should be noted that these two guide strips 3, arranged one above the other, guide rainwater and dust along the gaps between the strips on the clamping surface of the clamping plate 22, preventing water and dust accumulation at the edge of the photovoltaic panel 4, reducing corrosion and shading, improving power generation efficiency, and reducing the frequency of cleaning and maintenance. Simultaneously, they form two independent guide gaps, so even if one gap is obstructed by debris or localized water accumulation, the other can still maintain its drainage function, significantly improving drainage reliability. The vertical distribution design disperses the gravitational potential energy of rainwater onto two guide paths, avoiding water impact or splashing caused by concentrated drainage at a single point. Especially during heavy rain, the dual channels can more efficiently guide water flow to drain quickly along the inclined surface of the photovoltaic panel 4. The two strips form multi-point contact, increasing the contact area between the clamping plate 22 and the edge of the photovoltaic panel 4 compared to a single strip design. This reduces the risk of photovoltaic panel 4 displacement under vibration or wind load conditions, while also preventing stress concentration at the edge of the photovoltaic panel 4 due to excessive clamping.

[0041] In some embodiments, such as Figures 1-4 As shown, the support frame 1 adopts a prism frame structure with a right-angled triangle cross section. Its top surface corresponds to the hypotenuse of the right-angled triangle. When the photovoltaic panel 4 is installed in the support frame 1, it forms a slope. It should be noted that the slope design can accelerate rainwater drainage and avoid water accumulation.

[0042] Installation process: Based on the width of the photovoltaic panel 4, select a suitable position on the mounting hole 52 of the angle steel 5, align the connecting hole 211 of the box body 21 with the mounting hole 52 of the angle steel 5, pass the bolt 25 through and fix it through the bottom locking nut 26. The spacing between adjacent boxes 21 must match the size of the photovoltaic panel 4 to ensure that the clamping plate 22 can clamp the edges of the two adjacent panels. After the photovoltaic panel 4 is clamped by the clamping plate 22, rotate the limiting nut 27 to the side wall of the box body 21 to complete the installation of the photovoltaic panel 4.

[0044] The above description is merely a specific embodiment of this application, but the scope of protection of this application 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 application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
