Abstract
Description
Technical Field
[0001] This application relates to the field of photovoltaic installation technology, and more specifically, to a waterproof component and a photovoltaic roof. Background Technology
[0002] Photovoltaic tiles are generally used on sloping building facades. They not only have the function of generating electricity, but also serve as building components and building materials. They can even enhance the aesthetic effect by changing the color of the photovoltaic tiles.
[0003] Currently, two adjacent photovoltaic tiles are connected directly by overlapping. In areas with heavy rainfall, this can easily lead to rainwater backflow, creating a safety hazard.
[0004] To solve the above problems, in related technologies, refer to Figure 1 and Figure 2 Typically, a waterproof component 2 is installed at the overlap between two photovoltaic tiles 1. However, due to errors caused by processing, in actual applications, the conventional waterproof component 2 cannot completely cover the gap 3 between the two photovoltaic tiles, posing a risk of water leakage. Summary of the Invention
[0005] Given that conventional waterproofing components cannot completely cover the gap between two photovoltaic tiles, leading to the risk of leakage, the purpose of this application is to provide a waterproofing component and a photovoltaic roof. This waterproofing component can completely cover the gap between two photovoltaic tiles, thereby helping to improve the waterproofing effect.
[0006] Therefore, the first aspect of this application is to propose a waterproof component.
[0007] The second aspect of this application is to propose a photovoltaic roof.
[0008] In view of this, according to the first aspect of this application, a waterproof component is provided, which is disposed at the overlapping joint of a first component and a second component; the waterproof component includes: a waterproof body, the upper side of which contacts the first component and the lower side of which contacts the second component; a drip edge having a connecting side and a free side; the connecting side being connected to the upper side of the waterproof body; the free side being disposed opposite to the connecting side and being able to swing downward under the weight of the first component; and structural adhesive disposed on the lower side of the waterproof body to contact the second component.
[0009] In practical applications, uneven gaps may occur when the first and second components overlap, and due to manufacturing errors, conventional waterproofing components cannot completely seal the gaps between the first and second components, posing a risk of leakage. This application utilizes the aforementioned waterproofing component, which, while completely covering the gap between the second component and the waterproof body with structural adhesive, also allows the drip edge to swing downwards under the weight of the first component to absorb gap errors, thus ensuring complete coverage of the gap between the first component and the waterproof body. This achieves excellent waterproofing by completely covering the gap between the first and second components.
[0010] In some technical solutions, optionally, the waterproof body includes a first side, a second side, a third side, and a fourth side; the first and third sides are opposite to each other and spaced apart; the second and fourth sides are opposite to each other and spaced apart; wherein the second side connects the first and third sides; and the fourth side connects the first and third sides. This defines a frame structure. The frame structure has good stability, allowing the waterproof body to support the first component during overlap, preventing hard contact between the first and second components, thus enabling the waterproof body to also protect both the first and second components.
[0011] In some technical solutions, optionally, the drip edge extends obliquely from the first side in a direction away from the third and fourth sides, or the drip edge extends obliquely from the second side in a direction away from the third and fourth sides. In this way, during installation, the free side of the drip edge can be rotated downwards without any other operation, which facilitates installation. At the same time, after installation, the drip edge is not visible from the outside, which helps to ensure the aesthetics of the overall appearance.
[0012] In some technical solutions, optionally, the second and fourth sides extend in a direction away from the first side to form protrusions, and a receiving groove is formed between the protrusions and the third side to receive structural adhesive. This prevents structural adhesive from overflowing, thereby helping to improve the waterproofing effect.
[0013] In some technical solutions, optionally, a boss is provided in the receiving groove, which extends from the third side in a direction away from the first side, and the boss divides the receiving groove into two parts.
[0014] During installation, structural adhesive is filled into the position of the boss, allowing it to flow to both sides of the receiving groove under the action of the boss. This ensures that the structural adhesive and the surface of the second component are in full contact, so that the structural adhesive completely covers the gap between the second component and the waterproof body, thereby helping to improve the waterproof effect.
[0015] In some technical solutions, an overlap strip may optionally be included; the overlap strip is connected to the waterproof body; wherein the overlap strip extends from the second side in a direction away from the fourth side. In practical applications, the underside of the overlap strip is also provided with adhesive. This adhesive serves as a positioning agent before the structural adhesive cures, thereby helping to improve the waterproofing effect.
[0016] According to a second aspect of this application, a photovoltaic roof is also proposed, comprising photovoltaic modules and a waterproof component of any of the foregoing technical solutions; wherein the waterproof component is disposed on the photovoltaic modules. This allows the photovoltaic roof to possess all the beneficial effects disclosed in any of the aforementioned technical solutions, which will not be elaborated further here.
[0017] In some technical solutions, optionally, the photovoltaic module includes multiple photovoltaic tiles; the multiple photovoltaic tiles are connected by overlapping; the upper side of the overlap of the photovoltaic tiles contacts the lower side of the waterproof body; the lower side of the overlap of the photovoltaic tiles contacts the upper side of the waterproof body; and a drip edge is used to seal the gap formed between the upper side of the waterproof body and the lower side of the overlap of the photovoltaic tiles. This solves the problems existing in related technologies and effectively improves the waterproofing effect of the photovoltaic roof.
[0018] In some technical solutions, the photovoltaic roof also includes multiple keels, which are arranged equidistantly and parallel to each other; and multiple hangers, each of which is installed on the photovoltaic tile and connected to the keel so that the photovoltaic tile is fixed to the keel.
[0019] In the above technical solution, the mounting component includes a first connecting part and a second connecting part; the first connecting part is connected to the photovoltaic tile; and the second connecting part is connected to the keel.
[0020] In some technical solutions, the second connection part has a hook forming in the direction away from the photovoltaic tile, and the hook is engaged with the keel. This facilitates the installation of the mounting bracket and effectively improves the stability of the mounting bracket.

[0036] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0037] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.
[0038] The following is combined Figures 3 to 7The waterproof components and photovoltaic roofs provided in this application will be described in detail through specific embodiments and application scenarios.
[0039] Reference Figure 3 Some embodiments of this application disclose a waterproof component 100, which is disposed at the overlapping joint of the first component and the second component, and its structure includes a waterproof body 110, a water-repellent strip 120 and structural adhesive 130.
[0040] Specifically, the upper side of the waterproof body 110 contacts the first component, and the lower side contacts the second component to form the main waterproof structure. The drip edge 120 is connected to the upper side of the waterproof body 110, with the side where the drip edge 120 and the waterproof body 110 are connected serving as the joining side, and the side opposite to the joining side serving as the free side; and the free side can swing downwards under the action of the first component (e.g., ...). Figure 3 (As indicated by the middle arrow). Structural adhesive 130 is applied to the underside of the waterproof body 110 to abut against the second component.
[0041] In practical applications, uneven gaps may occur when the first and second components overlap, and due to processing errors, conventional waterproofing components cannot completely seal the gaps between the first and second components, posing a risk of leakage. This application utilizes the aforementioned waterproofing component 100, which, while completely covering the gap between the second component and the waterproof body 110 with structural adhesive 130, also allows the drip edge 120 to swing downwards under the weight of the first component to absorb gap errors, thus ensuring complete coverage of the gap between the first component and the waterproof body 110. This complete coverage of the gap between the first and second components achieves a good waterproofing effect.
[0042] In the above implementation, refer to Figure 4 and Figure 5 The waterproof body 110 has a frame structure, which has good stability. This allows the waterproof body 110 to support the first component during overlap, preventing the first and second components from making hard contact. This also gives the waterproof body 110 the function of protecting the first and second components.
[0043] Specifically, the waterproof body includes a first side 113, a second side 114, a third side 115, and a fourth side 116. The first side 113 and the third side 115 are opposite to each other and spaced apart; the second side 114 and the fourth side 116 are opposite to each other and spaced apart; the second side 114 connects the first side 113 and the third side 115; and the fourth side 116 connects the first side 113 and the third side 115. This defines the frame structure of the waterproof body 110.
[0044] In some embodiments, for ease of installation, the drip edge 120 extends obliquely from the first side 113 in a direction away from the third side 115 and the fourth side 116. This allows the drip edge 120 to be rotated downwards on its free side without additional operation during installation, facilitating installation. Furthermore, after installation, the drip edge 120 is not visible, contributing to the overall aesthetic appeal. It is understood that the drip edge 120 can also extend obliquely from the second side 114 in a direction away from the third side 115 and the fourth side 116.
[0045] Reference Figure 4 and Figure 5 In some embodiments, the second side 114 and the fourth side 116 extend in a direction away from the first side 113 and form protrusions. A receiving groove 111 is formed between the protrusions and the third side to receive the structural adhesive 130. This prevents the structural adhesive 130 from overflowing, thereby helping to improve the waterproofing effect.
[0046] In the above embodiment, a boss 112 is provided in the receiving groove 111. The boss 112 extends from the third side 115 in a direction away from the first side 113, and divides the receiving groove 111 into two parts. During installation, structural adhesive 130 is filled at the position of the boss 112, so that the structural adhesive 130 flows to both sides of the receiving groove 111 under the action of the boss 112. In this way, the structural adhesive 130 can fully contact the surface of the second component, so that the structural adhesive completely covers the gap between the second component and the waterproof body 110, thereby helping to improve the waterproof effect.
[0047] In some embodiments, the waterproof component 100 further includes an overlap strip 140 for connecting to a second component, thereby fixing the waterproof component 100 to the second component, which can achieve positioning before the structural adhesive 130 cures, thus helping to improve the waterproof effect.
[0048] Specifically, the overlap strip 140 is connected to the waterproof body 110; wherein, the overlap strip 140 extends from the second side 114 in a direction away from the fourth side 116. In practical applications, the lower side of the overlap strip 140 is provided with adhesive 150. Before installation, the protective film of the adhesive 150 is peeled off, allowing the waterproof component 100 to be fixed to the second component. In this way, the adhesive 150 serves as a positioning element before the structural adhesive 130 cures, thereby helping to improve the waterproof effect.
[0049] Reference Figure 6 and Figure 7 In some embodiments, this application also discloses a photovoltaic roof, including a photovoltaic module 200 and a waterproof component 100 disclosed in any of the above embodiments. Specifically, the waterproof component is disposed on the photovoltaic module. This allows the photovoltaic roof to possess all the beneficial effects disclosed in any of the above technical solutions, which will not be elaborated further here.
[0050] In some embodiments, the photovoltaic module 200 includes a plurality of photovoltaic tiles 210; the plurality of photovoltaic tiles 210 are connected by overlapping; the upper side of the overlap of the photovoltaic tile 210 contacts the lower side of the waterproof body 110; the lower side of the overlap of the photovoltaic tile 210 contacts the upper side of the waterproof body 110; and a drip edge 120 is used to seal the gap formed between the upper side of the waterproof body 110 and the lower side of the overlap of the photovoltaic tile 210. This solves the problems existing in the related art, thereby effectively improving the waterproofing effect of the photovoltaic roof.
[0051] For example, the photovoltaic tile 210 is a curved tile, and the curved edges of two adjacent photovoltaic tiles 210 are connected by overlapping. The waterproof component 100 is disposed at the overlap position between two adjacent photovoltaic tiles 210.
[0052] In related technologies, because the radius of curvature of the upper surface of a photovoltaic tile differs from the thickness of the tile itself by the radius of curvature of the lower surface, uneven gaps occur when two adjacent photovoltaic tiles overlap. Combined with manufacturing errors, conventional waterproofing components cannot cover the gaps between adjacent photovoltaic tiles, posing a risk of leakage. However, this application's embodiment addresses this by installing a waterproofing component 100, as disclosed in any of the aforementioned embodiments, between two adjacent photovoltaic tiles 210. First, a main seal is formed by the waterproofing body 110. Simultaneously, structural adhesive 130 completely covers the gap between the lower photovoltaic tile 210 and the lower side of the waterproofing body 110. Furthermore, the up-and-down movement of the drip edge 120 ensures that it completely covers the gap between the upper photovoltaic tile 210 and the upper side of the waterproofing body 110. This solves the problems existing in related technologies and effectively improves the waterproofing effect of the photovoltaic roof 300.
[0053] Specifically, the photovoltaic roof also includes multiple keels 310 and multiple hangers 320. The multiple keels 310 are arranged parallel to each other at equal intervals; each hanger 320 is installed on the photovoltaic tile 210 and connected to the keel 310 so that the photovoltaic tile 210 is fixed to the keel 310.
[0054] In some embodiments, the mounting bracket 320 includes a first connecting portion 321 and a second connecting portion 322; the first connecting portion 321 is connected to the photovoltaic tile 210; and the second connecting portion 322 is connected to the keel 310. Specifically, the first connecting portion 321 is inserted into the edge of the photovoltaic tile 210 located below the overlapping position, and the second connecting portion 322 is fixed to the keel 310 by screws.
[0055] In some embodiments, the straight edge of the photovoltaic tile 210 is provided with a connecting frame 220, which can effectively protect the photovoltaic tile 210 and facilitate the installation of the photovoltaic tile 210.
[0056] In some embodiments, the second connecting portion 322 has a hook 323 formed in the direction away from the photovoltaic tile 210, and the hook 323 engages with the keel 310. This facilitates the installation of the mounting bracket 320 and effectively improves the stability of the mounting bracket 320.
