Description

Technical Field

[0001] The present application relates to the field of photovoltaic technology, and in particular to a drip tile and a photovoltaic roof. Background Art

[0002] With the widespread application of the photovoltaic industry, photovoltaic tiles that combine the functions of traditional tiles and photovoltaic power generation have appeared on the market. Photovoltaic tiles are laid on the roof of a building to form a photovoltaic roof. The converted electricity can be used for self-powered building, and the excess electricity can be connected to the local power grid.

[0003] However, there are still some problems in the installation process of photovoltaic tiles. In the related art, photovoltaic tiles are usually installed outdoors. When encountering strong winds and other weather conditions, they are easily damaged and have a high loss rate. They need to be constantly maintained, which increases the maintenance and replacement costs. Utility Model Content

[0004] The present application aims to solve at least one of the technical problems existing in the prior art or related art.

[0005] To this end, a first aspect of the present application is to provide a drip tile.

[0006] The second aspect of the present application is to provide a photovoltaic roof.

[0007] In view of this, according to the first aspect of the present application, a drip tile is proposed, which includes: a substrate having a contoured surface matching the roof tile to be attached; an adhesive groove is formed on the contoured surface; a drip portion is arranged on one side of the length direction of the substrate; and the drip portion extends in a direction away from the contoured surface.

[0008] In practical applications, adhesive is first injected into the adhesive groove to connect and fix the drip tile and the roof tile to be attached, and the drip portion is located in front of the roof tile, so that the drip portion effectively blocks wind and rain, and the bottom edge of the roof has good water and wind blocking functions. In this way, damage to the roof can be avoided, which helps to reduce costs. Furthermore, the adhesive groove is used to limit the adhesive, which can prevent the adhesive from overflowing, thereby helping to improve the connection strength between the drip tile and the roof tile, and further improve the windproof ability of the drip tile.

[0009] In some technical solutions, optionally, at least two foam strips are disposed opposite to each other and spaced apart on the contouring surface; the two foam strips and the contouring surface form a glue groove.

[0010] Since foam has the characteristics of elasticity, light weight, fast pressure-sensitive fixation, easy use and free bending, etc. Therefore, by arranging foam on the contoured surface and forming an adhesive groove with the contoured surface, it is possible to effectively avoid damage to drip tiles and roof tiles during installation.

[0011] In the above technical solution, a first adhesive tape bonding layer is provided on the side opposite to the contoured surface. The first adhesive tape bonding layer forms a detachable connection between the foam and the contoured surface, so that in practical applications, the distance between the foams can be adjusted according to the windproof level requirements of the roof, thereby controlling the bonding area of ​​the adhesive, which is more practical.

[0012] In practical application, the other side of the foam away from the contoured surface is provided with a second adhesive tape adhesive layer. During installation, the foam and the roof tile are connected by the second adhesive tape adhesive layer, so that the drip tile and the roof tile are pre-fixed, so that the wind resistance of the drip tile can be guaranteed before the adhesive is cured.

[0013] In some technical solutions, optionally, a fixing hole penetrating the base plate is provided on the contoured surface. In actual application, by providing a fixing hole on the base plate that matches the tile hanging strip of the roof tile, the drip tile and the tile hanging strip are connected and fixed, which can effectively improve the stability of the drip tile and prevent the drip tile from falling off, making it safer to use and more practical.

[0014] In some technical solutions, optionally, the fixing holes and the foam are arranged at intervals along the length direction of the substrate, thereby effectively improving the connection stability of the drip tile.

[0015] In some technical solutions, the drip tile may further include a cylindrical portion, which is disposed on one side of the substrate in the width direction and smoothly transitions to the contoured surface of the substrate. This design can improve the structural stability of the drip tile and facilitate the manufacture of a substrate with a contoured surface having a high curvature.

[0016] In some technical solutions, the dripping surface of the dripping part is optionally a planar structure, so that the water on the tile surface of the dripping tile can be in a plane when dripping, which can prevent the meandering rainwater from easily getting the ground or people wet. Furthermore, the dripping edge of the dripping part is a wavy structure, which helps to guide the flow of rainwater and quickly discharge it.

[0017] According to the second aspect of the present application, the present application proposes a photovoltaic roof, comprising a support frame, a photovoltaic module and a drip tile as in any of the above technical solutions. The photovoltaic module is arranged on the tile hanging strip of the support frame; the drip tile is arranged at the bottom edge of the photovoltaic module; and the adhesive groove is filled with adhesive. In this way, the photovoltaic roof has all the beneficial effects disclosed in any of the above technical solutions, which will not be repeated here.

[0018] In some technical solutions, optionally, the photovoltaic module includes a plurality of photovoltaic tiles spliced ​​together; the photovoltaic tiles are in a continuous concave-convex wave shape; the contoured surface is a concave arc surface, and the curvature of the arc surface is the same as the curvature of the trough section of the photovoltaic tile, so that the contoured surface and the photovoltaic tile fit closely.

[0019] Additional aspects and advantages of the present application will become apparent in the following description or will be learned through practice of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0031] Combine the following Figures 1 to 5, the drip tile and photovoltaic roof provided in the embodiment of the present application are described in detail through specific embodiments and their application scenarios.

[0032] like Figure 1 and Figure 2 As shown, in an embodiment of the present application, a drip tile 100 is provided, comprising: a substrate 110 and a drip portion 120 .

[0033] Specifically, the upper surface of the substrate 110 is a contoured surface 111 that matches the roof tile to be attached; the contoured surface 111 is provided with a plurality of grooves along the width direction of the substrate 110 ( Figure 2 The dripping portion 120 is disposed in the longitudinal direction ( Figure 2 The front side of the substrate 110 is formed on the front side of the substrate 110 and extends away from the contour surface 111 on the lower surface of the substrate 110, that is, downward ( Figure 2 Extending in the downward direction (the downward direction of the up-down direction).

[0034] In practical applications, such as Figure 3 As shown, firstly, the adhesive 150 is injected into the adhesive groove 112, so that the drip tile 100 and the roof tile to be attached are connected and fixed, and the drip portion 120 is located in front of the roof tile, so that the drip portion effectively blocks wind and rain, so that the bottom edge of the roof has good water and wind blocking functions. In this way, damage to the roof can be avoided, which helps to reduce costs. Furthermore, the adhesive 150 is limited by the adhesive groove 112, which can prevent the adhesive 150 from overflowing, thereby helping to improve the connection strength between the drip tile 100 and the roof tile.

[0035] It is understandable that the distribution form of the adhesive grooves 112 can be changed arbitrarily, such as linear grooves in the length direction, or S-shaped distribution grooves, etc., and the present embodiment is not limited thereto.

[0036] In some embodiments, two foams 130 are arranged opposite to each other and spaced apart on the contour surface 111, and the two foams 130 and the contour surface 111 form a glue groove 112. Since the foam 130 has the characteristics of elasticity, light weight, rapid pressure-sensitive fixation, convenience in use and free bending, in this embodiment, by arranging the foam 130 on the contour surface 111 and forming the glue groove 112 with the contour surface 111, it is possible to effectively avoid damage to the drip tile and the roof tile during installation. It is understandable that the foam 130 can also be three or four strips, etc., and this embodiment is not limited thereto.

[0037] In the above embodiment, the first adhesive tape bonding layer is provided on the opposite side of the foam 130 and the contoured surface 111, that is, the foam 130 and the contoured surface 111 are detachably connected. In this way, in practical applications, the distance between the foams 130 can be adjusted according to the windproof level requirements of the roof, thereby controlling the bonding area of ​​the adhesive 150. Exemplarily, the distance between the foams 130 is between 5 mm and 20 mm.

[0038] In practical applications, the other side of the foam 130 away from the contoured surface 111 is provided with a second adhesive tape layer, that is, the foam 130 and the roof tile are connected by the second adhesive tape layer. In this way, during installation, the drip tile 100 can be pre-fixed on the roof tile by the first adhesive tape layer and the second adhesive tape layer, so that the wind resistance of the drip tile 100 can be ensured before the adhesive 150 is cured.

[0039] In order to ensure the bonding depth of the adhesive 150 and improve the aging resistance of hot and cold shrinkage, in some embodiments, the thickness of the foam 130 is between 2 mm and 20 mm.

[0040] In some embodiments, the contoured surface 111 is provided with a fixing hole 113 that passes through the base plate 110. In actual application, by providing the base plate 110 with a fixing hole 113 that matches the tile hanging strip of the roof tile, the drip tile 100 and the tile hanging strip are connected and fixed, which can effectively improve the stability of the drip tile 100 and prevent the drip tile 100 from falling off, making it safer to use and more practical.

[0041] In the above embodiment, the fixing holes 113 and the foam 130 are arranged at intervals, which can effectively improve the connection stability of the drip tile 100.

[0042] In some embodiments, the drip tile 100 further includes a cylindrical portion 140. The cylindrical portion 140 is disposed on one side of the substrate 110 in the width direction and smoothly transitions to the contoured surface 111 of the substrate 110. This design can improve the structural stability of the drip tile 100 and facilitate the manufacture of a substrate with a contoured surface having a high curvature.

[0043] In some embodiments, the drip surface 121 of the drip portion 120 is a planar structure, so that the water on the tile surface of the drip tile 100 can be in a plane when dripping, which can prevent the winding rain from wetting the ground or people.

[0044] In the above embodiment, the outer edge (drip edge) of the drip portion 120 is in a wave-shaped structure, which helps to guide the flow and quickly discharge rainwater.

[0045] In some embodiments, Figure 4 and Figure 5As shown, the present application also discloses a photovoltaic roof 200, including a support frame 210, a photovoltaic assembly 220 and a drip tile 100 disclosed in any of the above embodiments. In this way, the photovoltaic roof 200 has all the beneficial effects disclosed in any of the above embodiments, which will not be repeated here.

[0046] Specifically, the photovoltaic module 220 is arranged on the tile hanging strip 211 on the support frame 210. The drip tile 100 is arranged at the bottom edge of the photovoltaic module 220; and the adhesive groove 112 is filled with adhesive 150.

[0047] Exemplarily, the adhesive 150 is a silicone structural adhesive.

[0048] In some embodiments, the photovoltaic assembly 220 includes a plurality of photovoltaic tiles 221 spliced ​​together. The photovoltaic tile 221 is in a continuous concave-convex wave shape, that is, the photovoltaic tile 221 has at least one continuous trough section 222 and a peak section 223. Among them, the contoured surface 111 is a concave arc surface, and the curvature of the arc surface is equal to the curvature of the trough section 222 of the photovoltaic tile 221, so that the contoured surface 111 and the trough section 222 of the photovoltaic tile 221 fit closely, that is, the drip tile 100 is set at the trough section of the photovoltaic tile 221.
