Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic panel brackets, and in particular to a modular photovoltaic panel bracket system. Background Art

[0002] Photovoltaic panel bracket is a special bracket designed for placing, installing and fixing photovoltaic panels in photovoltaic power generation systems.

[0003] An existing photovoltaic module matrix structure with a 10° inclination (application number 202311100170.2) includes east-west modules and north-south modules, which can be applied to different regions and are provided with multiple windbreaks. Its structure is simple and stable. However, it is found that there are still certain inconveniences during use. For example, photovoltaic panels of different sizes require different windbreaks of different specifications. During production and manufacturing, it is necessary to produce a variety of specifications for stocking, which undoubtedly increases the stocking cost of production and manufacturing. Therefore, the utility model proposes a modular photovoltaic panel bracket system with a simple structure and the ability to reduce costs. Utility Model Content

[0015] The beneficial effects of the utility model are:

[0016] Saving stocking costs, the photovoltaic panels are installed through the rear feet provided by the utility model, which can make the edges of the photovoltaic panels extend beyond the rear feet to form a cantilever structure. In the symmetrical state, there is no need to fix two photovoltaic panels on the same rear foot at the same time, so that when installing photovoltaic panels of different specifications, the windproof side panels can be formulated as standard parts with uniform specifications, and the specifications of the windproof middle panels can be changed. In addition, when the modular photovoltaic panel bracket system is set to a symmetrical state, the number of installed windproof side panels is much larger than the number of windproof middle panels. Designing components with larger demand as standard parts can save stocking costs. When it needs to be set to a unilateral state, the windproof middle panel is not needed, and the same components as those in the symmetrical state can be used. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Reference Figure 1-8 As shown, a modular photovoltaic panel 2 support system includes a photovoltaic panel 2 and a frame base 1. The frame base 1 is formed by at least two horizontally placed guide rails 11 and two longitudinally placed guide rails 11 fixed to each other. According to actual needs, connectors are provided at the connection points to connect the guide rails 11. The size of the frame base 1 is selected according to actual conditions. The frame base 1 also includes a T-block 12 and an L-block 13. The T-block 12 and the L-block 13 are fixed to the guide rail 11 by bolts to improve the convenience of installation of the frame base 1.

[0033] The front foot 6 and the rear foot 5, wherein the front foot 6 and the rear foot 5 are fixed to the guide rail 11 by bolts and blocks, and the positions of the front foot 6 and the rear foot 5 can be adjusted by loosening the bolts and the blocks, the front foot 6 includes a front connecting portion 62 for connecting to the pressure block assembly 9, and a front mounting portion 61 for connecting to the guide rail 11; the rear foot 5 includes a rear mounting portion 53 connected to the guide rail 11 and a rear connecting portion 55 connected to the pressure block assembly 9, the rear foot 5 is integrally formed with a front plate 51 and a rear plate 52, the rear plate 52 is provided with a second mounting hole 54, the second mounting hole 54 can be used to install the windproof backboard 10, the front mounting portion 61 and the rear mounting portion 53 are both provided with a boss portion for clamping with the slide groove on the guide rail 11, which can prevent the front foot 6 and the rear foot 5 from rotating after being installed on the guide rail 11.

[0034] The height of the front foot 6 is smaller than that of the rear foot 5, so that the photovoltaic panel 2 can be tilted at a certain angle after installation, which can improve the intensity of light. The photovoltaic panel 2 is fixed to the top of the front foot 6 and the rear foot 5 through a pressing block assembly 9, wherein the pressing block assembly 9 includes a middle pressing block and a side pressing block, both of which are prior arts, easy to use and stable in structure. The middle pressing block is arranged between two adjacent photovoltaic panels 2. One middle pressing block can press two adjacent photovoltaic panels 2 at the same time, while the side pressing block presses one photovoltaic panel 2 at a time, and is used for the outer side of the photovoltaic panel 2 at the edge position.

[0035] The left and right sides of the front foot 6 and the rear foot 5 are both provided with first mounting holes 8 for mounting and fixing the windproof side plate 3. The rear foot 5 is integrally formed with a front plate 51 and a rear plate 52, and the rear plate 52 is provided with a second mounting hole 54.

[0036] The windproof side plate 3 closes the side opening formed between the guide rail 11, the photovoltaic panel 2, the front foot 6 and the rear foot 5, which can prevent wind from blowing into the bottom of the photovoltaic panel 2 from the side and causing impact on the photovoltaic panel 2 support system, thereby improving the stability of the structure. The windproof side plate 3 includes a low end portion 31 and a high end portion 32, the low end portion 31 corresponds to the front foot 6, and the high end portion 32 corresponds to the rear foot 5. The overall side surface formed by the combination of the guide rail 11, the photovoltaic panel 2, the front foot 6 and the rear foot 5 is a right-angled trapezoid.

[0037] The ballast component 7 is arranged on the frame base 1. The ballast component 7 can adopt heavy objects such as cement bricks to increase the weight of the entire frame base 1 and improve the wind resistance of the entire support system.

[0038] When the modular photovoltaic panel 2 support system is set to a symmetrical state, it is suitable for areas with higher latitudes and also includes a windproof middle plate 4. At this time, the photovoltaic panels 2 are arranged in two rows and tilted to both sides respectively. At least two front feet 6 and two rear feet 5 are required to be provided on the same longitudinally arranged guide rail 11, so that the photovoltaic panel 2 and the guide rail 11 form an isosceles triangle structure. The windproof middle plate 4 is used to connect two adjacent and symmetrically arranged high-end parts 32, connect two adjacent windproof side panels 3, prevent wind from blowing in from the middle, and is locked together with the windproof side panels 3 on the first mounting hole 8 by bolts.

[0039] When the modular photovoltaic panel 2 support system is set to a single-sided state, it is suitable for areas with lower latitudes and further includes a windproof backboard 10, which is fixed to the second mounting hole 54 by bolts.

[0040] like Figure 9-10 As shown, the photovoltaic panel 2 is set to a long side fixed state, and the upper end surfaces of the front foot 6 and the rear foot 5 are respectively provided with a front support portion 63 and a rear support portion 56, and the front support portion 63 and the rear support portion 56 both extend out of the side of the front foot 6 and the rear foot 5 to form a cantilever structure, the purpose is that in some special cases, the installation and fixation of the photovoltaic panel 2 requires the pressing block assembly 9 to be set at the long side position of the photovoltaic panel 2, but the photovoltaic panel 2 usually needs to place the long side horizontally, and the front support portion 63 and the rear support portion 56 can increase the contact area between the photovoltaic panel 2 and the front foot 6 or the rear foot 5, forming a better support and improving the support strength. The above description is only a preferred embodiment of the utility model, and is not used to limit the utility model. For those skilled in the art, the utility model can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
