Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic tiles, in particular to a photovoltaic tile substrate and a photovoltaic tile. Background Art

[0002] Building integrated photovoltaics is a method of integrating photovoltaic products into buildings. The photovoltaic modules are used as part of the building rather than simply installed on the building, thus achieving a perfect combination of the building and renewable energy. This technology not only has the power generation function but also can meet the structural, safety, and aesthetic requirements of the building. By using solar energy for power generation, the consumption of traditional energy is reduced, and the building operation cost is lowered, which conforms to the development trend of green buildings. The synchronous design and construction of the photovoltaic modules and the building make the whole system more stable and reliable, reducing the later maintenance cost. With the continuous development of the global economy, the consumption of traditional energy is increasing day by day, and the energy crisis and environmental problems are becoming increasingly prominent. Therefore, searching for and developing renewable energy and achieving sustainable development have become a global consensus. People's understanding of green buildings and renewable energy is constantly improving, and building integrated photovoltaics has gradually been recognized and accepted by the market. More and more building projects are beginning to adopt building integrated photovoltaics technology, promoting the popularization and application of this technology.

[0003] Electrical components usually need to be connected to the back of the photovoltaic tile. If the electrical components get water, they are extremely likely to be damaged.

[0046] In order to make the purpose, technical solution and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments.

[0047] As Figures 1 to 4 Combined with Figures 10 to 12As shown in the figure, the present utility model provides a photovoltaic tile substrate, including: a substrate main body 100, the substrate main body 100 is used for installing a photovoltaic panel 200, an upper part at the front end of the substrate main body 100 is provided with a transverse notch 120, a lower part at the rear end of the substrate main body 100 is provided with a second rib 161, and the transverse notch 120 and the second rib 161 of the adjacent substrate main bodies 100 cooperate with each other. One side at the front end of the substrate main body 100 is provided with a first docking portion 150 extending backward, and one side at the rear end of the substrate main body 100 away from the first docking portion 150 is provided with a second docking portion 170. The first docking portion 150 and the second docking portion 170 of the adjacent substrate main bodies 100 cooperate with each other and form a waterproof seal. A longitudinal notch 151 is opened on the first docking portion 150, and a second drain port 124 is opened at one end of the transverse notch 120 close to the second docking portion 170. After the adjacent substrate main bodies 100 on the left and right cooperate, the second drain port 124 communicates with the longitudinal notch 151. The transverse notches 120 on the adjacent substrate main bodies 100 on the left and right communicate with each other.

[0048] In this embodiment, the third rib 122 extends to the front end of the second drain port 124. When the adjacent substrate main bodies 100 on the left and right are installed, the second drain port 124 of the substrate main body 100 on the right communicates with the longitudinal first notch 1511 of the substrate main body 100 on the left.

[0049] In this embodiment, the second drain port 124 is opened on one side of the longitudinal second rib 1712 away from the longitudinal first rib 1711, and the position of the longitudinal second rib 1712 below the second drain port 124 deviates in a direction away from the longitudinal first rib 1711. During use, the rainwater in the transverse notch 120 can flow through the second drain port 124 into the longitudinal first notch 1511, avoiding the accumulation of rainwater in the transverse notch 120. In the above embodiment, there is a certain gap between the longitudinal second rib 1712 and the bottom of the longitudinal first notch 1511, enabling the rainwater to quickly drain away in the longitudinal first notch 1511, while preventing a large amount of rainwater from splashing into the longitudinal second notch 1512.

[0050] The bottom edge of the rear end face of the substrate main body 100 protrudes backward to form a transverse first rib 160. When the adjacent substrate main bodies 100 are installed vertically, the transverse first rib 160 of the substrate main body 100 located above is arranged below the transverse notch 120 of the substrate main body 100 located below.

[0051] A section of the lower end of the first docking portion 150 is cut off to form a first drain port 152. The first drain ports 152 of the adjacent substrate main bodies 100 on the left and right are blocked by the transverse first rib 160, so that the water in the longitudinal notch 151 flows into the transverse notch 120 of the lower substrate main body 100.

[0052] In this embodiment, during actual use, the rainwater on the upper photovoltaic tile flows down to the next layer of photovoltaic tile. Under the action of the wind, a part of the rainwater flows upward in a countercurrent manner. Due to the blockage of the transverse first rib 160, only a small amount of rainwater can pass through the gap between the upper photovoltaic tile and the lower photovoltaic tile and enter the transverse notch 120, and then drain away from both sides of the substrate body 100. For the adjacent photovoltaic tiles on the left and right, the rainwater may enter the longitudinal notch 151 through the gap between the first docking portion 150 and the second docking portion 170. The water in the longitudinal notch 151 flows to the lower end of the longitudinal notch 151 and enters the transverse notch 120 of the next layer of photovoltaic tile through the first drain port 152 and then drains away. Thus, rainwater is prevented from seeping into the rear end of the photovoltaic tile.

[0053] In this embodiment, the water in the transverse notch 120 and the longitudinal notch 151 will not flow to the surface of the photovoltaic panel 200, which can effectively reduce the residence time of rainwater on the surface of the photovoltaic panel 200, thereby preventing a large amount of algae from growing.

[0054] As Figures 6 to 9 shown, in order to further improve the waterproof effect of the photovoltaic tile, the lower side of the transverse notch 120 protrudes forward to form a first rib 121. When the upper and lower adjacent substrate bodies 100 are installed, the transverse first rib 160 of the upper substrate body 100 is arranged below the first rib 121 of the lower substrate body 100.

[0055] In this embodiment, the setting of the first rib 121 can further improve the ability to block the countercurrent of rainwater. The first rib 121 and the transverse first rib 160 jointly block the rainwater flowing upstream, allowing less rainwater to enter the transverse notch 120.

[0056] A transverse second rib 161 is provided at the lower part of the rear end face of the substrate body 100. The transverse second rib 161 is arranged above the transverse first rib 160. The lower side face of the transverse second rib 161 is flush with the lower end face of the first docking portion 150 or the lower side face of the transverse second rib 161 is located above the lower end face of the first docking portion 150, and the transverse second rib 161 is inserted into the transverse notch 120.

[0057] In this embodiment, the transverse second rib 161 can guide the water discharged from the first drain port 152 into the transverse notch 120 of the lower layer. At the same time, it can prevent a large amount of rainwater from entering the third notch 130 from the transverse notch 120 in extreme weather conditions.

[0058] The transverse slot 120 includes a first transverse slot 1201 and a second transverse slot 1202 which are arranged in sequence from bottom to top. A third ridge 122 is formed between the first transverse slot 1201 and the second transverse slot 1202. When the upper and lower adjacent substrate bodies 100 are installed, the second transverse ridge 161 of the upper substrate body 100 is inserted into the first transverse slot 1201 of the lower substrate body 100.

[0059] In this embodiment, the transverse notch 120 is divided into two waterproof grooves, so that the rainwater flowing upstream needs to first climb over the first transverse notch 1201 before entering the second transverse notch 1202, which increases the difficulty of rainwater climbing over from the upper part of the front end surface of the substrate body 100 to enter the rear end surface of the substrate body 100. In addition, the second transverse convex strip 161 is inserted into the first transverse notch 1201, so that it is more difficult for the water in the first transverse notch 1201 to enter the second transverse notch 1202. Through the above arrangement, even under extreme weather conditions, it is difficult for rainwater to overflow from the upper part of the front end of the substrate body 100 to the rear end of the substrate body 100, and the water is quickly drained from both ends of the substrate body 100. In other embodiments, the second transverse convex strip 161 of the upper substrate body 100 is inserted into the second transverse notch 1202 of the lower substrate body 100.

[0060] The top surface of the substrate body 100 is provided with a water baffle 131, which protrudes forward to the front end surface of the protruding substrate body 100, and the water baffle 131 extends above the first docking portion 150. The upper side wall of the transverse notch 120 protrudes forward to the front end surface of the protruding substrate body 100 to form a second convex strip 123, and a third notch 130 is formed between the second convex strip 123 and the water baffle 131, and the third notches 130 of the substrate bodies 100 adjacent to each other are connected to each other.

[0061] In this embodiment, the water retaining plate 131 is integrally formed with the substrate body 100. The third notch 130, the first transverse notch 1201, and the second transverse notch 1202 form multiple lines of defense above the front end of the substrate body 100, and combined with the arrangement of the first transverse convex strip 160, the second transverse convex strip 161, the first convex strip 121, the second convex strip 123, and the third convex strip 122, the waterproof capability of the top of the front end of the substrate body 100 is greatly improved, even if the rainwater breaks through the second transverse notch 1202, the wider third notch 130 has better drainage capability, and the third notch 130 can drain the rainwater overflowing from the transverse notch 120, and prevent the rainwater from flowing back into the roof.

[0062] The second docking portion 170 is provided with longitudinal ridges 171 along its length direction, and the longitudinal ridges 171 are clamped with the longitudinal notches 151. The longitudinal notches 151 include a longitudinal first notch 1511 and a longitudinal second notch 1512 arranged in sequence from left to right. The longitudinal ridges 171 include a longitudinal first ridge 1711 and a longitudinal second ridge 1712. The longitudinal first ridge 1711 is close to the first docking portion 150, and the longitudinal second ridge 1712 is located on the side of the longitudinal first ridge 1711 away from the first docking portion 150. The longitudinal first ridge 1711 cooperates with the longitudinal second notch 1512, and the longitudinal second ridge 1712 cooperates with the longitudinal first notch 1511.

[0063] In this embodiment, rainwater enters the longitudinal first notch 1511 from the gap between two adjacent substrate bodies 100 on the left and right, and drains along the longitudinal first notch 1511. Through the arrangement of the longitudinal second ridge 1712, the rainwater is blocked from overflowing the longitudinal first notch 1511 and entering the longitudinal second notch 1512. Also, because the longitudinal second ridge 1712 is offset in the direction away from the longitudinal first ridge 1711 at a position below the second drain port 124, the longitudinal second ridge 1712 fits against the left side wall of the longitudinal first notch 1511, effectively preventing a large amount of rainwater from entering the longitudinal first notch 1511 from the gap between two adjacent substrate bodies 100 on the left and right. At this time, the longitudinal second ridge 1712 is in a Z shape, or in a broken line shape. The longitudinal first notch 1511, the longitudinal second notch 1512, the longitudinal second ridge 1712, and the longitudinal first ridge 1711 cooperate with each other to form two lines of defense, effectively preventing rainwater from overflowing from the edges of the two substrate bodies 100 to the back of the photovoltaic tile. Through the structural design of the two drain grooves and the ridges, the waterproof problem of the lap joint of the left and right photovoltaic tiles is solved. In the above embodiment, there is a certain distance between the longitudinal second ridge 1712 and the bottom of the longitudinal first notch 1511 (the side close to the rear end face of the substrate body 100), and there is a certain distance between the longitudinal first ridge 1711 and the bottom of the longitudinal second notch 1512 (the side close to the rear end face of the substrate body 100).

[0064] A section of the top end of the second docking portion 170 is cut off to form a third docking groove 140, and the water baffle 131 is arranged along the contour of the third docking groove 140; on the side where two adjacent substrate bodies 100 on the left and right are close to each other, the third docking groove 140 of one substrate body 100 cooperates with the water baffle 131 of the other substrate body 100.

[0065] As Figure 3 and Figure 13 shown, in this embodiment, the distance from the top end of the third docking groove 140 to the top surface of the substrate body 100 is d, and the thickness of the water baffle 131 is h, then d = 2h. The docking of the third docking groove 140 and the water baffle 131 improves the structural stability after the installation of the photovoltaic tile.

[0066] A plurality of buckles 1311 are provided on the top of the substrate main body 100. The buckles 1311 are rotatably connected to the substrate main body 100. After rotation, the buckles 1311 protrude to the rear end of the substrate main body 100. In this embodiment, two buckles 1311 are provided on the top of the substrate main body 100. Before installing the substrate main body 100, the buckles 1311 can completely coincide with the upper surface of the substrate main body 100, that is, the buckles 1311 do not protrude to the rear end of the substrate main body 100, so as to avoid deformation or breakage of the buckles 1311 during transportation. When installing the substrate main body 100, the buckles 1311 can be rotated to make the buckles 1311 protrude to the rear end of the substrate main body 100, so that the buckle 100 can clamp the purlin 300, facilitating the quick installation of the substrate main body 100.

[0067] In this embodiment, when installing the first row (the bottommost row) of photovoltaic tiles, the buckle 1311 is abutted against the upper surface of the second row of purlins 300, and the transverse second protrusion 161 is abutted against the lower surface of the first row (the bottommost row) of purlins 300, and then they are connected and fixed by screws; there are two ways to install the rear rows of photovoltaic tiles: after the buckle 1311 is abutted against the upper surface of the purlin 300, ① the transverse second protrusion 1611 is snapped into the transverse first notch 1201 at the front end of the substrate main body 100; ② the transverse second protrusion 1611 is snapped into the transverse second notch 1202 at the front end of the substrate main body 100, and then they are connected and fixed by screws; both installation methods can be installed quickly and can solve the waterproof problem.

[0068] A wedge-shaped boss 114 is fixedly connected to the upper part of the rear end face of the substrate main body 100. In this embodiment, four wedge-shaped bosses 114 are also provided on the back of the photovoltaic tile, optimizing the line contact between the substrate main body 100 and the purlin 300 into surface contact, that is, optimizing the line force into surface force, so that the photovoltaic tile fits better with the purlin 300.

[0069] Two installation platforms 132 are provided in the third notch 130, and installation holes 1321 are opened in the installation platforms 132. In this embodiment, the setting of the installation platforms 132 can prevent rainwater from entering the installation holes 1321. The installation holes 1321 are through holes, which can facilitate the screws to pass through.

[0070] An installation groove 110 for installing the photovoltaic panel 200 is opened on the substrate main body 100.

[0071] In this embodiment, a through groove 111 is formed in the middle of the installation groove 110, a plurality of structural grooves 113 are formed in the rear surface of the substrate body 100, a plurality of structural beams 112 are arranged between the structural grooves 113, a first wire groove 1121 is formed in the structural beam 112, and a second wire groove 1312 is formed in the rear end of the water baffle 131. The formation of the structural grooves 113 can reduce the use of materials and the weight of the substrate body 100, the structural beams 112 can improve the structural strength of the substrate body 100, and the arrangement of the first wire groove 1121 and the second wire groove 1312 facilitates wire management after the installation of the photovoltaic tiles.

[0072] As Figure 5 shown, a photovoltaic tile includes a photovoltaic panel 200 and a photovoltaic tile substrate, and the photovoltaic panel 200 is installed in the installation groove 110.

[0073] As Figures 5 to 7 shown, a photovoltaic tile installation assembly includes an installation bracket, a fixing member and a photovoltaic tile. The fixing member passes through the installation hole 1321 on the photovoltaic tile to fixedly connect the photovoltaic tile to the installation bracket.

[0074] In this embodiment, the installation bracket is a purlin 300, and the fixed connection is a screw or a bolt; during installation, the purlin 300 is installed on the roof of the building, and the buckle 1311 abuts against the upper surface of the purlin 300.

[0075] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
