Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic building component technology, specifically, it relates to a structure for an additional photovoltaic canopy for a rooftop photovoltaic power station. Background Technology

[0002] With the continuous development of building-integrated photovoltaics (BIPV) technology, photovoltaic canopies, as an important device for combining energy utilization with building functions, have been widely researched and applied. For example, the frame-type photovoltaic canopy patent with publication number CN221567712U achieves stable installation of the photovoltaic canopy by adding pre-embedded parts to the exterior wall of the building. However, this installation method has extremely high requirements for the early construction conditions of the building. For buildings without pre-embedded parts, installation is not possible, which greatly limits the installation location of the photovoltaic canopy and makes it difficult to meet the needs of diverse building scenarios.

[0003] Furthermore, the integrated photovoltaic canopy structure patent with announcement number CN118481314A adopts a technical solution of fixing the photovoltaic canopy to the exterior wall and internal steel beams of a building. However, in practical applications, when the exterior wall of a building has a decorative layer, this installation method inevitably requires damage to the exterior wall decorative layer, which not only seriously affects the overall aesthetics of the building, but also increases the complexity and cost of installation and construction, and may also damage the original structure of the building.

[0004] It is evident that existing photovoltaic canopy installation technologies suffer from limitations such as restricted installation conditions and damage to building appearance, making it difficult to meet the growing demand for photovoltaic canopy installations. There is an urgent need to propose a new installation method to solve the aforementioned technical problems. Utility Model Content

[0005] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide a structure for an additional photovoltaic canopy for a rooftop photovoltaic power station.

[0006] The structure of an additional photovoltaic canopy for a rooftop photovoltaic power station provided by this utility model includes purlin tie rods, purlins, diagonal beams, horizontal short columns, short column diagonal braces, uprights, and component fastening kits. The uprights are the original south-side uprights of the rooftop photovoltaic power station, serving as the supporting foundation for the canopy structure. Multiple horizontal short columns are welded to the south side of the middle of each upright. Diagonal beams are welded between the tail ends of the horizontal short columns on the same upright. Multiple diagonal beams together form an inclined support surface. Multiple purlins of equal length are welded to the inclined support surface. Multiple purlin tie rods are welded to the middle position between adjacent purlins. The photovoltaic modules are fixed to the purlin tie rods by the component fastening kits on the grid support surface.

[0007] In a preferred embodiment: each of the columns is provided with two horizontal short columns, which are arranged horizontally, and the length of the horizontal short column above the south side of the column is less than the length of the horizontal short column below the south side of the column.

[0008] In a preferred embodiment: one end of the short column brace is welded to the middle of the horizontal short column below the south side of the column, and the other end of the short column brace is welded to the column, forming a triangular support structure.

[0009] In a preferred embodiment: the purlin tie rod is arranged perpendicularly to the purlin, and the purlin tie rod and the purlin form a grid support surface.

[0010] In a preferred embodiment: each photovoltaic module has two purlin rods below it.

[0011] In a preferred embodiment: the component fastening kit includes an upper pressure plate, a U-bolt, a lower pressure plate, and a flange nut.

[0012] In a preferred embodiment: both ends of the photovoltaic module are provided with upper pressure plates at the bottom, the upper pressure plates are located above the purlin tie rods, and the upper pressure plates are provided with holes that match the U-bolts.

[0013] In a preferred embodiment: the two ends of the U-bolt are secured to both sides of the purlin tie rod, forming a wrap around the purlin tie rod.

[0014] In a preferred embodiment: the lower pressure plate is located below the purlin tie rod, and the two holes on the lower pressure plate fit over the two ends of the U-bolt, thus forming an upper and lower clamping structure with the upper pressure plate.

[0015] In a preferred embodiment, flange nuts are provided at both ends of the U-bolt.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. When using this utility model, it relies on the south-side column of the original photovoltaic power station as the supporting foundation, and forms an independent support system by welding horizontal short columns and inclined beams, completely eliminating the dependence on wall embedded parts or external wall structure. It can be installed in the eaves position with only floor slabs and cantilever beams, as well as in building scenarios without pre-reserved embedded parts, thus increasing the applicability of the structure.

[0018] 2. When this utility model is used, the canopy support surface composed of inclined beams, purlins and purlin tie rods adds photovoltaic module installation positions, thereby obtaining more power generation.

[0019] 3. The installation components of this utility model are installed in the rooftop power station area. The photovoltaic modules are clamped and fixed using component fastening kits. There is no need to drill holes in the exterior wall or damage the decorative layer, which ensures the overall aesthetics of the building, reduces the complexity and cost of installation and construction, and reduces damage to the original structure of the building.

[0027] like Figure 1-4The present invention discloses a structure for an additional photovoltaic canopy for a rooftop photovoltaic power station, including purlin tie rods 1, purlins 3, diagonal beams 4, horizontal short columns 5, short column braces 6, uprights 7, and component fastening kits 8. The uprights 7 are the original south-side uprights of the rooftop photovoltaic power station, serving as the supporting foundation for the canopy structure. Two horizontal short columns 5 are welded to the south side of the middle of each upright 7. The two horizontal short columns 5 are arranged horizontally, and the length of the upper horizontal short column 5 on the south side of the upright 7 is less than the length of the lower horizontal short column 5 on the south side of the upright 7. One end of the short column brace 6 is connected to the middle of the lower horizontal short column 5 on the south side of the upright 7. The short column diagonal brace 6 is welded to the column 7 at one end, forming a triangular support structure to enhance the stability of the overall installation structure. The two horizontal short columns 5 are welded together with a diagonal beam 4. Multiple diagonal beams 4 together form an inclined support surface. Two purlins 3 of equal length are welded on the inclined support surface. Multiple purlin tie rods 1 are welded in the middle between the two purlins 3. The purlin tie rods 1 are set perpendicular to the purlins 3. The purlin tie rods 1 and the purlins 3 form a grid support surface. The grid support surface fixes the photovoltaic module 2 to the purlin tie rods 1 through the component fastening kit 8. There are two purlin tie rods 1 below each photovoltaic module 2.

[0028] The component fastening kit 8 includes an upper pressure plate 9, a U-bolt 10, a lower pressure plate 11, and a flange nut 12. The upper pressure plate 9 is provided at the bottom of both ends of the photovoltaic module 2. The upper pressure plate 9 is located above the purlin tie rod 1. The upper pressure plate 9 has holes that match the U-bolt 10. The two ends of the U-bolt 10 are fastened to both sides of the purlin tie rod 1, forming a wrap around the purlin tie rod 1. The lower pressure plate 11 is located below the purlin tie rod 1. The two holes on the lower pressure plate 11 fit over the two ends of the U-bolt 10. The lower pressure plate 11 and the upper pressure plate 9 form an upper and lower clamping structure. The two ends of the U-bolt 10 are provided with flange nuts 12. By tightening the flange nuts 12, the upper pressure plate 9 and the lower pressure plate 11 clamp the inner frame of the photovoltaic module 2 and the purlin tie rod 1.

[0029] Working principle

[0030] In use, this utility model involves welding horizontal short columns 5 onto the south-side column 7 of the original photovoltaic power station, and welding inclined beams 4 onto the outer ends of the horizontal short columns 5. Simultaneously, short column braces 6 are welded between the lower horizontal short columns 5 and the column 7 to form a triangular support structure, thereby enhancing overall stability. The support system of the column 7 replaces traditional wall-embedded parts, allowing the installation position to be unrestricted by the wall, making it suitable for special locations such as eaves. Purlins 3 are welded onto the inclined beams 4, and purlin tie rods 1 are welded between the two purlins 3 to form a grid-like support surface. This grid support surface expands the installation space for the photovoltaic modules 2, increasing the installed capacity. A module fastening kit 8, consisting of an upper pressure plate 9, U-bolts 10, a lower pressure plate 11, and flange nuts 12, clamps and fixes the photovoltaic modules 2 to the purlin tie rods 1. The installation process does not involve exterior wall construction, avoiding damage to the building's appearance, thus solving the problems of limited installation location, damage to exterior wall decoration, and limited installed capacity due to roof area limitations in existing technologies.
