Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation equipment, in particular to a solar photovoltaic tile. Background Art

[0002] The main body of a solar photovoltaic tile generally adopts an integrated molded structure, consisting of an upper photovoltaic cell layer, a middle waterproof and heat-insulating layer, and a lower support and reinforcement layer, with a protective outer frame. The photovoltaic cell layer uses high-efficiency monocrystalline or polycrystalline silicon photovoltaic cells, which are tightly encapsulated between a transparent, high-strength glass cover and back panel through advanced packaging technology. The glass cover surface has undergone a special anti-reflection treatment to effectively reduce light reflection and improve sunlight absorption.

[0003] The waterproof and thermal insulation layer is a composite of a new polymer waterproof material and a high-efficiency thermal insulation material. The polymer waterproof material has excellent flexibility, weather resistance, and water resistance, effectively preventing rainwater penetration. The thermal insulation material is a foam material or aerogel material with low thermal conductivity, which significantly reduces heat transfer between indoor and outdoor spaces and improves the building's thermal insulation performance.

[0004] The support reinforcement layer must be equipped with multiple support structures, and each photovoltaic tile must be independently installed and supported. After the bracket is installed, the photovoltaic panels must be installed to ensure that they are connected one by one so that the seams can be covered with glue, which facilitates the installation and fixation of the photovoltaic tiles. However, this installation structure is very cumbersome to operate, requiring more welding and drilling. Not only do adjacent photovoltaic tiles need to be connected with wires, but they also need to be partially welded and bolted. It requires the cooperation of multiple workers to assemble the photovoltaic tiles, and the installation efficiency is relatively low.

[0005] The above-mentioned prior art has studied the importance of preventing leakage and improving installation strength. The main focus of this approach is on preventing leakage within the photovoltaic tile itself, specifically the leakage resistance of each layer. However, in practice, if the joints are not carefully constructed during the installation of the photovoltaic tile, rainwater can leak down and enter the back of the tile, causing short circuits and other faults. Therefore, the installation of photovoltaic tiles is more pressing than that of traditional tiles, requiring the joints to be fully protected from rainwater infiltration. Therefore, to fully prevent rainwater infiltration during the assembly of photovoltaic tiles, these tiles require a comprehensive application of sealant at the joints, resulting in a slow installation process. Furthermore, the photovoltaic panels assembled in this manner are too rigid, requiring extremely high precision in the construction of each panel; no single panel can exceed the required precision. Furthermore, due to summer heat stress, these panels are susceptible to cracking and even damage to the photovoltaic tiles themselves. Therefore, how to better prevent rainwater from penetrating after installation and how to more conveniently install and construct them is worthy of in-depth study by those skilled in the art. Summary of the Invention

[0006] In view of the above introduction to the current state of the art, the purpose of the present invention is to provide a solar photovoltaic tile to better solve the technical problems of existing photovoltaic tiles in fully avoiding rainwater penetration, complex installation and low construction efficiency.

[0009] Furthermore, the bottom surface of the straight plate section near its free end is integrally provided with a barb plate as a barb structure, so that the free end of the elastic plate is a V-shaped structure. When the straight plate section pushes the buckle plate to the intersection, the barb plate has completely slid upward out of the arc-shaped groove, and when the buckle plate then automatically slides down into the lower groove section, it is pressed down by the buckle plate to a position that fits with the back of the positioning boss.

[0010] Furthermore, the quick-plug assembly includes a locking pin elastically and telescopically installed in the first tile, the end face of the locking pin is a hemispherical surface, and also includes a plug pin that is linearly slidably installed along the inclination direction of the tile body and cannot rotate, the end face of the plug pin is a hemispherical surface, and the side face of the plug pin has a blind groove; when the plug pin is inserted into the socket in the first tile and the end face of the locking pin bounces into the blind groove, the two tiles are plugged and assembled.

DETAILED DESCRIPTION

[0021] The following is a comprehensive description of the embodiments of the present invention. Some core features of the embodiments are specifically illustrated in the accompanying drawings. In the drawings, the same or similar reference numerals represent the same or similar technical features, or structures, steps, or processes with similar functions. Other embodiments substituted by ordinary technicians based on these embodiments without requiring creative work also fall within the scope of protection of the present invention.

[0022] The solar photovoltaic tile in this embodiment, like the existing photovoltaic tile, includes a plate-shaped tile body, the upper surface of the tile body is a photovoltaic cell layer, and a protective frame is fixed on the outer edge of the tile body for easy installation and protection. Figure 1 The two adjacent tiles are connected by quick-connect components, and the quick-connect components make the two tiles form an inclined plate structure, which is convenient for quick installation on the roof. When making, specifically, for example, the tile body from low to high includes a first tile 1 and a second tile 2 that are plugged into each other. The upper edge of the first tile 1 on the side close to the second tile 2, such as Figure 1 As shown, there is a positioning boss 6, and the side of the positioning boss 6 facing the second tile 2 is recessed into a smooth arc-shaped groove 601. In addition, a raised positioning ridge 7 is designed on the side of the second tile 2 close to the first tile 1. The two sides of this positioning ridge 7 have a first arc-shaped concave surface and a second arc-shaped concave surface (not shown in the figure). After the two tiles are spliced together, the first arc-shaped concave surface is connected to the bottom surface of the arc-shaped groove 601 to form a mounting surface. Figure 3 In this embodiment, the elastic plate 3 is further detachably fixed to the second tile 2. The elastic plate 3 includes a straight plate section 301 and an arc plate section 302. The arc plate section 302 is embedded in the second arc-shaped concave surface. The angle between the straight plate section 301 and the arc plate section 302 is covered by the positioning ridge 7 to achieve the installation and positioning of the elastic plate 3. Specifically, the arc plate section 302 is fixed by the pressure plate 4 fixed to the second tile 2 by bolts. After the two tiles are plugged in and assembled, that is, Figure 1 As shown, the straight plate section 301 is bent inward along the arc groove 601, thereby forming a water retaining ditch capable of horizontal drainage. In essence, as shown in FIG. Figure 1 As shown, there are two curved drainage ditches, one large and one small. Rainwater received by each photovoltaic tile will be primarily discharged horizontally through these two ditches, rather than flowing down the tilt of the photovoltaic tile. This facilitates centralized drainage and minimizes erosion. The assembly structure at the joint between the two tiles in the above embodiment can be located within the photovoltaic tile frame to avoid affecting the photovoltaic power generation layer itself.

[0023] In this embodiment, Figure 1-Figure 2As shown, the first tile 1 is slidably mounted with an L-shaped gusset plate against the positioning boss 6. One side of the gusset plate, i.e., its lower side, is movably mounted in the mounting cavity within the first tile 1. A counterweight column 20 is fixed to one side of the gusset plate, and a smooth core column 21 is coaxially mounted at each end of the counterweight column 20. A chute 8 is formed on each of the two opposing side walls of the mounting cavity. The chute 8 includes an upper chute section 801 and a lower chute section 802 that intersect in a ∧ shape. The upper chute section 801 is arranged parallel to the tilted direction of the tile installation to facilitate the upward sliding of the gusset plate, while the lower chute section 802 is tilted downward to facilitate the sudden drop of the subsequent gusset plate after it slides into place. Initially, the core column 21 is preferably located in the upper chute section 801.

[0024] As one of the specific implementation structures, during the process of plugging and assembling two tiles, Figure 4-Figure 6 As shown, the end of the straight plate section 301 pushes the gusset plate to move upward along the upper groove section 801, that is, the gusset plate moves upward from Figure 2 In the initial state, the elastic plate 3 is Figure 3 Starting from the initial state, when it moves to the intersection of the upper groove section 801 and the lower groove section 802, due to the gravity of the counterweight column 20, it will automatically fall into the lower groove section 802, and thus squeeze the straight plate section 301 downward to expose the part of the positioning boss 6, so that it can be more closely attached to the bottom of the arc groove 601. Moreover, at this time, due to the special V-shaped structure of the slide groove 8, the buckle plate is not easy to be overturned when the water flow hits the water retaining ditch formed by the elastic plate 3, making the installation structure more secure.

[0025] like Figure 7-Figure 9 As shown, the straight plate section 301 of this embodiment has a barb plate 9 as a barb structure on its bottom surface at its free end, so that the free end of the elastic plate 3 is a V-shaped structure. When the straight plate section 301 pushes the gusset plate to the intersection, the barb plate 9 has completely slid upward out of the arc groove 601, and when the gusset plate then automatically slides down into the lower groove section 802, it is pressed down by the gusset plate to a position that fits with the back of the positioning boss 6, that is, Figure 7 The purpose of this structural design is to form a waterproof structure at the joint between two adjacent tiles in the inclined direction.

[0026] As an example, Figure 1 and Figure 10-11, this quick-plug assembly includes a locking pin 12 elastically and telescopically installed in the first tile 1, the end face of the locking pin 12 is a hemispherical surface, and also includes a plug 10 that is linearly slidably installed along the inclination direction of the tile body and cannot rotate. Specifically, a limit block can be set on the side wall of the plug 10, and the limit block can be linearly slidably installed in the second tile 2. This embodiment does not describe the existing conventional technical means in detail. During production, the end face of the plug 10 is a hemispherical surface, which is convenient for insertion, and the side of the plug 10 has a blind groove 18. In addition, when the plug 10 is inserted into the socket 101 in the first tile 1, and the end face of the locking pin 12 is ejected into the blind groove 18, the two tiles are automatically assembled. In order to avoid damage to the photovoltaic tiles due to impact during installation, during production, the plug 10 is located at one end of the second tile 2 and is elastically connected to the second tile 2 through a disc spring 11, and the disc spring 11 is used for buffering and vibration reduction.

[0027] like Figure 1 、 Figure 10 、 Figure 11 A mounting hole is provided at the bottom of the first tile 1. The mounting hole comprises a threaded hole section adjacent to the bottom surface of the first tile 1 and a smooth hole section for slidingly mounting a lock pin 12. An annular step is provided between the smooth hole section and the threaded hole section. A cylindrical spring 13 is connected between the annular step and the end surface of the lock pin 12. The cylindrical spring 13 is sleeved on a connecting column 14 to achieve elastic sliding mounting of the lock pin 12. A round table 16 is fixed to one end of the connecting column 14. The round table 16 is coaxially mounted in the lock pin 12 to achieve rotational engagement between the two. In addition, a screw plug 15 is fixed to the other end of the connecting column 14. The screw plug 15 can be threadedly matched with the threaded hole section. Moreover, the depth of the cylindrical hole 17 for the installation of the truncated cone 16 in the lock pin 12 needs to be able to allow the two to slide relative to each other in the axial direction for a certain distance. Accordingly, the depth of the blind groove 18 needs to be greater than the radius of the hemispherical end of the lock pin 12. This is to avoid that the depth of the lock pin 12 that normally bounces into the latch 10 cannot be too long in order to ensure smooth engagement. For example, if it exceeds the radius of the hemispherical surface, it may not be able to be plugged in smoothly. When disassembly is required, the screw plug 15 can be loosened and pulled outward to release the latch 10. In order to facilitate operation, an operating hole with a hexagonal groove can be provided on the end face of the screw plug 15 to fit an hexagonal wrench, and the opening of the socket 101 is a trumpet-shaped structure to facilitate insertion and installation.

[0028] In the above embodiments, Figure 3 The pressure plate 4 includes an arc-shaped trough section 401 with an arc-shaped cross section and a straight strip section. The arc-shaped trough section 401 is used to coaxially extrude the arc section 302 and is also used for drainage. The strip section is embedded in the second outer surface and fastened with bolts, which is convenient for installation, disassembly and maintenance.

[0029] The photovoltaic tiles in the above embodiment are mainly based on the horizontal drainage design. The final drainage solution needs to be designed according to the structure of the top of the on-site building and the drainage requirements. This embodiment does not impose any necessary restrictions or explanations. However, as a recommended design, the photovoltaic tiles also have a drainage groove 19 to cooperate with the adjacent two pairs of assembled tiles. Figure 12 There is a downward-sloping drainage trough 19 on the ground. The water retaining ditch of the elastic plate 3 can drain water into the drainage trough 19, so that the water is discharged in a concentrated manner along the inclined direction, avoiding rainwater overflowing and flowing on the photovoltaic tiles, reducing the degree of rainwater erosion received by some photovoltaic tiles, and then improving the anti-leakage ability.

[0030] The above series of specific implementation details are merely some preferred embodiments of the present invention and cannot be used to limit the scope of protection of the claims of the present invention. Ordinary technicians in this field can simply change the design ideas based on their understanding of the above embodiments and reference to the basic principles recorded in the claims of the present invention. However, these changed designs still fall within the scope of protection of the invention.
