[0030] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0031] Reference below Figure 1-Figure 3 A photovoltaic roof assembly 100 according to an embodiment of the present invention is described.

[0032] Combination Figure 1 and Figure 2 As shown, the photovoltaic roof assembly 100 according to the utility model can mainly include: a roof component 10 and a photovoltaic component 20, wherein the roof component 10 is used to be connected to the roof beam 200 of the industrial plant, and the photovoltaic component 20 is arranged on the side of the roof component 10 away from the roof beam 200, and the photovoltaic component 20 is connected and fixed to the roof component 10.

[0033] Specifically, the photovoltaic roof assembly 100 is applied as a whole to the roof of an industrial plant. By connecting the roof component 10 to the roof beam 200 of the industrial plant, the roof component 10 can be used as the roof of the industrial plant to meet the requirements of heat insulation, waterproofing, and load-bearing, thereby ensuring the normal use of the industrial plant. By arranging the photovoltaic component 20 on the side of the roof component 10 away from the roof beam 200, the photovoltaic component 20 can make full use of the roof area of ​​the industrial plant for photoelectric conversion.

[0034] Furthermore, different from the prior art in which the photovoltaic components and the roof components are separated, the roof components are first connected to the roof beams, and then a photovoltaic mounting structure is set up to install the photovoltaic components. By connecting and fixing the photovoltaic components 20 to the roof components 10, that is, the photovoltaic components 20 can be directly installed on the roof components 10, and there is no need to set up a separate mounting structure for the photovoltaic components 10. This not only reduces costs, but also facilitates the installation and construction of the photovoltaic roof assembly 100, reduces construction difficulty, and simplifies the construction process.

[0035] Therefore, by connecting and fixing the photovoltaic component 20 to the roof component 10, the photovoltaic component 20 can be directly installed on the roof component 10 without separately setting up a mounting structure for the photovoltaic component 10, which not only reduces costs but also facilitates the installation and construction of the photovoltaic roof assembly 100, reduces construction difficulty, and simplifies the construction process.

[0036] Combination Figure 2 and Figure 3 As shown, the roof assembly 10 is provided with a buckle 11, and the photovoltaic assembly 20 is provided with a slot 21, and the buckle 11 is engaged with the slot 21. Specifically, by providing the buckle 11 on the roof assembly 10 and the buckle 11 on the photovoltaic assembly 20, when the photovoltaic assembly 20 is provided on the roof assembly 10, it is only necessary to engage the buckle 11 with the slot 21 to achieve the connection and fixation between the photovoltaic assembly 20 and the roof assembly 10, which can make the connection and fixation between the photovoltaic assembly 20 and the roof assembly 10 simpler and more convenient.

[0037] Furthermore, the buckle 11 can mainly include: a first buckle part, a second buckle part and a third buckle part, the third buckle part is arranged above the first buckle part and parallel to the first buckle part, the second buckle part is connected between the first buckle part and the third buckle part and is bent relative to the first buckle part and the third buckle part, so that the buckle 11 can conform to the relative position between the roof component 10 and the photovoltaic component 20, and the buckle 11 can be set on the roof component 10 by only connecting the first buckle part to the roof component 10, and the buckle 11 can be snap-fitted with the photovoltaic component 20 by only snap-fitting the third buckle part with the slot 21, so that the cooperation between the photovoltaic component 20 and the roof component 10 can be simple and reliable.

[0038] Combination Figure 2 and Figure 3 As shown, the photovoltaic roof assembly 100 may also include: a first fastener 17, a first perforation 121 is provided on the roof component 10, a second perforation is provided on the first buckle part, the first perforation 121 and the second perforation correspond to each other, and the first fastener 17 sequentially penetrates the first perforation 121 and the second perforation and connects and fixes the roof component 10 and the buckle 11. Specifically, by providing the first perforation 121 on the roof component 10 and the second perforation on the first buckle part, after the buckle 11 is provided on the roof component 10, it is only necessary to make the first perforation 121 and the second perforation correspond to each other, and then make the first fastener 17 sequentially penetrate the first perforation 121 and the second perforation, so that the roof component 10 and the buckle 11 can be connected and fixed, thereby making the arrangement of the buckle 11 on the roof component 10 simpler and more reliable.

[0039] Combination Figure 2 and Figure 3 As shown, there are multiple photovoltaic modules 20, and the multiple photovoltaic modules 20 are arranged at intervals on the roof module 10, and each photovoltaic module 20 is provided with a slot 21 on both sides of the width direction. Specifically, in order to adapt to the roof area of ​​the industrial plant, multiple photovoltaic modules 20 can be provided, and the multiple photovoltaic modules 20 are arranged at intervals on the roof module 10, so that the lighting area can be guaranteed. By providing the slots 21 on both sides of the width direction of each photovoltaic module 20, and correspondingly providing the buckles 11 on the roof module 10, the multiple buckles 11 can be used to engage with the slots 21 on the width direction of the photovoltaic module 20 to achieve stable support for each photovoltaic module 20, thereby improving the structural reliability of the photovoltaic roof assembly 100 and ensuring the lighting area of ​​the photovoltaic roof assembly 100.

[0040] Combination Figure 2 and Figure 3As shown, a wiring groove 122 is provided on the roof component 10, and the wiring groove 122 is located below the photovoltaic component 20. There are multiple wiring grooves 122, and the multiple wiring grooves 122 correspond one by one to the multiple photovoltaic components 20. In this way, the cables of the multiple photovoltaic components 20 can be correspondingly arranged in the wiring grooves 122. The wiring grooves 122 can accommodate the cables, thereby avoiding the disorder of the cables and ensuring the order and neatness of the cable routing. The structural design of the roof component 10 can be further optimized, and the structural reliability of the photovoltaic roof assembly 100 can be improved.

[0041] Combination Figure 1-Figure 3 As shown, the roof assembly 10 may include: a corrugated steel sheet 12, and a buckle 11 is provided on the corrugated steel sheet 12. Specifically, by making the roof assembly 10 include the corrugated steel sheet 12, the buckle 11 can be provided on the corrugated steel sheet 12 on the premise that the corrugated steel sheet 12 plays the role of blocking water and light, so that the photovoltaic assembly 20 can be installed through the corrugated steel sheet 12, so that the corrugated steel sheet 12 plays a supporting role for the photovoltaic assembly 20, so that the structure of the roof assembly 10 can be fully utilized, and there is no need to set up an additional installation structure, which can make the structure of the roof assembly 10 and even the photovoltaic roof assembly 100 simpler, and make the connection between the roof assembly 10 and the photovoltaic assembly 20 simpler and more reliable.

[0042] Specifically, when the corrugated steel sheet 12 with a corrugated cross-section is formed by roller cold bending, it is only necessary to form a first perforation 121 on the convex groove of the corrugated steel sheet 12, and the groove on the corrugated steel sheet 12 can be used as a wiring groove 122. This not only ensures the structural strength of the corrugated steel sheet 12, but also simplifies the structural design of the corrugated steel sheet 12.

[0043] Furthermore, the thickness of the corrugated steel sheet 12 is d, and d satisfies the relationship: 1.5mm<d<2.5mm. Specifically, by setting the thickness of the corrugated steel sheet 12 within a reasonable range, it is possible to prevent the thickness of the corrugated steel sheet 12 from being too small, resulting in insufficient structural strength of the corrugated steel sheet 12 and insufficient support of the corrugated steel sheet 12 for the photovoltaic module 20, and it is also possible to prevent the thickness of the corrugated steel sheet 12 from being too large, resulting in excessive weight of the corrugated steel sheet 12 and waste of cost, thereby achieving a balance between the structural strength and weight of the corrugated steel sheet 12, ensuring reliable support of the corrugated steel sheet 12 for the photovoltaic module 20, and improving the reliability of the roof module 10 and even the photovoltaic roof assembly 100.

[0044] Combination Figure 1 and Figure 2As shown, the roof assembly 10 may also include: a purlin 13, which may mainly include: a first connection portion 131, a second connection portion 132 and a third connection portion 133, the first connection portion 131 is connected to the roof beam 200, the third connection portion 133 is spaced above the first connection portion 131 and parallel to the first connection portion 131, the second connection portion 132 is connected between the first connection portion 131 and the third connection portion 133 and is bent relative to the first connection portion 131 and the third connection portion 133, and the third connection portion 133 is connected and fixed to the corrugated steel sheet 12.

[0045] Specifically, by arranging the purlin 13, the third connection part 133 is arranged above the first connection part 131 and parallel to the first connection part 131, and the second connection part 132 is connected between the first connection part 131 and the third connection part 133 and is bent relative to the first connection part 131 and the third connection part 133. In this way, the purlin 13 can conform to the relative position of the roof assembly 10 and the roof beam 200. It is only necessary to connect the first connection part 131 to the roof beam 200 and connect and fix the third connection part 133 to the corrugated steel sheet 12 to achieve the connection between the roof assembly 10 and the roof beam 200, complete the arrangement of the roof assembly 10 and the photovoltaic roof assembly 100 on the roof beam 200, and make the arrangement of the roof assembly 10 and the photovoltaic roof assembly 100 on the roof beam 200 simpler and more convenient.

[0046] It should be noted that there are multiple purlins 13, and multiple purlins 13 are connected to the roof beams 200, which can divide the roof of the industrial plant into sections, thereby facilitating the installation of the photovoltaic roof assembly 100. The specific number and location of the purlins 13 can be determined according to the span of the plant.

[0048] Specifically, the insulation support 14, the insulation cotton 15 and the waterproof breathable membrane 16 are stacked in sequence, the insulation support 14 is arranged on the purlin 13, and the corrugated steel sheet 12 is arranged on the side of the waterproof breathable membrane 16 away from the insulation cotton 15, so as to form the basic structure of the roof assembly 10. Among them, the insulation support 14 can play the role of insulation and support, the insulation cotton 15 can play the role of insulation, the waterproof breathable membrane 16 can play the role of waterproof and breathable, and the corrugated steel sheet 12 can play the role of water and light blocking, so that the roof assembly 10 can meet the requirements of heat insulation, waterproofing, weather resistance, fire resistance, load bearing, etc. of the industrial plant roof, and ensure the normal operation of the roof assembly 10 and even the photovoltaic roof assembly 100.

[0049] Furthermore, by setting a second fastener 18, the second fastener 18 is sequentially passed through the corrugated steel plate 12, the waterproof breathable membrane 16, the insulation cotton 15 and the insulation support 14, and is fixedly connected to the third connecting portion 133 of the purlin 13, so that the connection of the components in the roof assembly 10 can be achieved, ensuring the structural stability and reliability of the roof assembly 10.
