Description

Technical Field

[0001] This invention relates to the field of photovoltaic module installation technology, and in particular to a basket-shaped photovoltaic tile. Background Technology

[0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy using the photovoltaic effect at the semiconductor interface. Large-area photovoltaic modules can be formed by connecting solar cells in series and then encapsulating them for protection. These modules can be applied to building roofs. Current solutions for waterproofing building roofs mainly include: 1. Horizontal connections on the frame, followed by vertical sealing using adhesive strips or sealant; 2. Adding a water-guiding channel below the connection points where leakage is possible; 3. Combining photovoltaic cells and components to form photovoltaic tiles, such as combining them with ceramic or polymer materials and shaping these materials into tile-like shapes; 4. Using special connectors to guide water out of the roof in both directions.

[0003] While existing technologies each have their own characteristics, they are not entirely effective in addressing the waterproofing issues at longitudinal and transverse splicing seams and cross-shaped intersections during photovoltaic module assembly. The waterproofing problem remains unresolved throughout the long 25-year lifespan of photovoltaic modules. Furthermore, existing solutions often suffer from complex structures, difficult manufacturing, challenging installation, high costs, and limited widespread adoption. Solving the waterproofing problem throughout the product's lifespan requires an inherently waterproof structure, ensuring that seasonal changes like temperature fluctuations and frost do not alter its waterproof nature, similar to traditional Chinese glazed tiles. Therefore, this invention develops a basket-shaped photovoltaic tile to address the problems in existing technologies. A search revealed no identical or similar technical solutions.

[0054] The present invention will be further described in detail below with reference to specific embodiments:

[0055] like Figure 1As shown, a basket-shaped photovoltaic tile includes several photovoltaic modules 1, water-blocking connectors 2, and side span connectors 3.

[0056] Combination Figure 2 As shown, several photovoltaic modules 1 are installed on the roof purlins 01, arranged at an angle, as... Figure 3 As shown, the photovoltaic module 1 includes a glass panel 11 and several photovoltaic cells 12, with a blank glass 13 at the top of the glass panel 11; each photovoltaic module 1 has a frame 4 around its perimeter, such as... Figure 4 As shown, the frame 4 includes an upper frame 41, a lower frame 42, a left frame 43, and a right frame 44 forming a trapezoid. The upper dimension (d1) of the trapezoidal structure is at least 4mm larger than the lower dimension (d2). The left frame 43 and the right frame 44 are engaged with the side of the glass plate 11. The upper frame 41 and the lower frame 42 are both located below the photovoltaic module 1, that is, below the glass plate 11.

[0057] The trapezoidal design of frame 4 is to facilitate effective overlap between adjacent photovoltaic modules 1 distributed longitudinally; that is, the smaller end of the upper frame 4 can be inserted into the larger end of the lower frame 4. The specific structure of frame 4 is as follows:

[0058] Combination Figure 4 As shown, the left border 43 and the right border 44 are symmetrically arranged and both have a single integrated structure, as... Figure 7-10 As shown, it includes a profile 431 with a "U"-shaped cross-section, an upper support plate 432 and a lower support plate 433 extending sequentially from the upper and lower ends of the profile 431 to the same side, a vertical plate 434 extending upward from the upper end of the profile 431, an upper clamping plate 435 perpendicular to the vertical plate 434, and a clamping strip 436 extending upward from the upper clamping plate 435; a groove 437 for snapping the photovoltaic module 1 is formed between the upper clamping plate 435 and the upper support plate 432; as Figure 8 , Figure 11 As shown, the upper ends of the left frame 43 and the right frame 44 are cut off by the upper card plate 435 and card strip 436. Figure 8 The area marked by the grid shaded lines in the middle forms an upper gap. Figure 11 (The area corresponding to the medium-thick solid line); such as Figure 10 , Figure 12 As shown, the lower end has cut off the profile 431 and the lower support plate 433. Figure 10 The grid shaded area in the middle), forming a lower gap; the extension structure corresponding to the lower gap ( Figure 12 The thick solid line section can be effectively inserted into the upper notch, thereby enabling the overlapping of the photovoltaic modules 1 distributed along the longitudinal direction.

[0059] like Figure 13 , Figure 14As shown, the upper surfaces of both sides of the upper frame 41 have first notches 411 for the upper support plate 432 to fit, and the lower surfaces of both sides have second notches 412 for the lower support plate 433 to fit. After the upper frame 41 is fitted with the left frame 43 and the right frame 44 at both ends, it is locked and fixed by bolts.

[0060] like Figure 15 , Figure 16 As shown, the upper surfaces of both sides of the lower frame 42 have a third notch 421 for the upper support plate 432 to fit, and the sides have a fourth notch 422 for the profile 431 to fit. The lower support plate 433 at the corresponding installation position is cut off. After the two ends of the lower frame 42 are fitted with the left frame 43 and the right frame 44, they are locked and fixed by bolts.

[0061] It should be noted that, in order to ensure that the vertically distributed photovoltaic modules 1 can be effectively overlapped, the height of the lower frame 42 perpendicular to the end face of the photovoltaic module 1 is greater than the height of the upper frame 41, thereby raising the lower end of the frame 4 so that it can be smoothly overlapped on top of the next layer of frame 4, as shown below. Figure 17 As shown, that is: the extended structure corresponding to the lower notch ( Figure 12 The thick solid line portion can be effectively inserted at the upper notch; at the same time, the height of the upper frame 41 is set to d3, and the distance between the upper end face of the lower frame 42 and the lower end face of the fourth notch is d4. To ensure fit, d3 = d4.

[0062] Since the frame is trapezoidal in shape, the corresponding glass panel 11 can be set in the following two ways:

[0063] Firstly, the glass plate 11 has a rectangular structure, combined with... Figure 5 As shown, gaskets 5 are provided between the upper ends of the glass plate 11 and the grooves 437 of the left frame 43 and the right frame 44, respectively. Figure 6 As shown, the gasket 5 has a straight edge 51 and a beveled edge 52, with a hole in the middle. The straight edge 51 is attached to the outer wall of the photovoltaic module 1, and the beveled edge 52 is attached to the inner wall of the groove 437. The beveled edge 52 has a groove in the middle. By adding the gasket 5, the gaps on both sides of the glass plate 11 can be made equal, and the gap for inserting the previous photovoltaic module 1 can be filled.

[0064] Secondly, the glass plate 11 has a trapezoidal structure, and its two sides directly abut against the inner wall of the tank 437.

[0065] After the photovoltaic module 1 is installed in the frame 4, the two sides and the groove 437 can be sealed by conventional methods such as applying glue. The blank glass 13 at the top of the glass plate 11 is opposite to the upper notch. Based on the structural design of the frame 4, the lower end of the photovoltaic module 1 at the top of the vertically distributed photovoltaic module 1 overlaps with the blank glass 13 at the top of the photovoltaic module 1 at the bottom. The lower notch of the left frame 43 and the upper notch of the right frame 44 match the upper notch. There is also a water-blocking tape 14 arranged horizontally in the overlapping area. In this embodiment, two water-blocking tapes 14 are provided to play a double water-blocking role. In order to ensure that the glass plate 11 overlaps but is not stressed, the height difference between the upper frame 41 and the lower frame 42 should be equal to or slightly higher than the sum of the height difference of the glass plate 11 overlap and the height of the water-blocking tape 14.

[0066] like Figure 18 , Figure 19 As shown, adjacent photovoltaic modules 1 distributed laterally are fixedly installed using water-blocking connectors 2; the water-blocking connectors 2 include a longitudinal beam 21, several pressure blocks 22, self-tapping screws 23, and a cover plate 24; the longitudinal beam 21 is fixed to the purlin 01 and supports the left frame 43 and right frame 44 on the sides of two adjacent photovoltaic modules 1, and the upper end face is concave in the length direction to form a groove 211; the pressure blocks 22 are pressed at both ends onto the profiles 43 of the left frame 43 and right frame 44. On the upper surface of 1, the self-tapping screw 23 is positioned and penetrates through the groove 211, thereby connecting the pressure block 22 and the longitudinal beam 21; the cover plate 24 is connected to the pressure block 22, and its two ends are respectively covered on the left frame 43 and the right frame 44. The end has a first water-blocking adhesive strip 25, which is attached to the upper surface of the photovoltaic module 1. The upper end of the clip 436 is also connected to a second water-blocking adhesive strip 26, which is attached to the inner surface of the cover plate 24.

[0067] The first water-blocking strip 25 and the second water-blocking strip 26 primarily serve to block water, but water seepage can still occur. The main reasons for this seepage are: firstly, when the outside wind is strong, the air pressure at the outer end of the cover plate 24 is lower than the internal air pressure, making it easier for rainwater to seep in; secondly, the first water-blocking strip 25 and the second water-blocking strip 26 themselves have capillary pores in their structure, which also make them prone to seepage based on the siphon principle. Therefore, even if a small amount of rainwater seeps in through the first water-blocking strip 25, it can be drained longitudinally along the area at the outer end of the retaining strip 436 due to the obstruction of the retaining strip 436. When a small amount of rainwater seeps in through the second water-blocking strip 26, it can be drained longitudinally along the area formed between the retaining strip 436 and the retaining strip 434 due to the obstruction of the upright plate 434. Therefore, the first water-blocking strip 25 and the second water-blocking strip 26 provide a double water-blocking function, and even if a small amount of water seeps in, it can be drained by relying on the structure of the left frame 43 and the right frame 44.

[0068] At the same time, due to the height difference between the upper border 41 and the lower border 42, combined with Figure 17 As shown, there is an angle between the left frame 43 and the right frame 44 and the corresponding longitudinal beam 21, thus forming a gap 6. The gap 6 gradually increases from the side where the upper frame 41 is located to the side where the lower frame 42 is located. Also, when the pressure block 22 is installed, the left frame 43 and the right frame 44 will deform under the action of the self-tapping screw 23, which will cause the photovoltaic module 1 to deform. Therefore, a pad 61 is provided between the left frame 43 and the right frame 44 and the longitudinal beam 21. The self-tapping screw 23 passes through the pad 61 and connects the pressure block 22 and the longitudinal beam 21. The pad 61 mainly plays a supporting role to prevent the photovoltaic module 1 from deforming and affecting its service life.

[0069] Regarding the design of the cover plate 24, it is snapped onto the seam between adjacent photovoltaic modules 1. Adjacent photovoltaic modules 1 distributed laterally share a single cover plate 24, and several cover plates 24 distributed longitudinally are also combined using an overlapping method. Figure 20 As shown, the lower end of the upper cover plate 24 overlaps with the upper end of the lower cover plate 24, and a drip edge sealing head 241 is provided at the overlap position.

[0070] like Figure 21 As shown, a side span connector 3 is provided at the longitudinal edge. The side span connector 3 includes a longitudinal beam 21, several side span pressure blocks 31, self-tapping screws 23, a side span cover plate 32, and a side span connection cover 33. The longitudinal beam 21 supports the left frame 43 / right frame 44 on the side of the photovoltaic module 1. One end of the side span pressure block 31 is pressed onto the left frame 43 / right frame 44, and the other end extends downward and presses onto the upper surface of the longitudinal beam 21. The self-tapping screws 23 connect the side span pressure block 31 and the longitudinal beam 21. The side span cover plate 32 is connected to the side span pressure block 31, and one end extends and covers the left frame 43 / right frame 44. The side span connection cover 33 covers the side span cover plate 32 and is fixed to the wall.

[0071] The present invention designs the frame 4 as a trapezoidal structure, which facilitates the effective overlap of the photovoltaic modules 1 distributed along the longitudinal direction, saving 10% of the cost compared with the traditional installation method; the photovoltaic modules 1 distributed along the transverse direction are connected by water-blocking connectors 2, and the design of the first water-blocking strip 25 and the second water-blocking strip 26 plays a double water-blocking role, and the service life of the overall structure can reach 25-30 years.

[0072] The above embodiments are merely illustrative of the technical concept and features of the present invention, intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly, and should not be construed as limiting the scope of protection of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
