Description

Technical Field

[0001] This invention relates to the field of new energy product manufacturing technology, and in particular to a combined solar energy tile. Background Technology

[0002] In the early stages of new energy development, the government encouraged market investors to invest in distributed photovoltaic systems to support the photovoltaic industry. Currently, residential distributed photovoltaic systems are all installed by mounting photovoltaic panels on existing wooden roof tiles using brackets. These systems essentially lack the functionality of tiles and have significant design flaws in the face of extreme weather conditions. They are also prone to fires due to changing environments. Furthermore, they are generally implemented by investors leasing rooftops, resulting in overly simplistic use of photovoltaic panels and a complete reliance on the national grid for power supply. The inherent instability of photovoltaic power generation poses a significant risk to the national grid.

[0003] Currently, the country is still focusing on the development of the new energy industry, advocating zero-carbon buildings and zero-carbon industrial parks, and encouraging residents and businesses to install distributed photovoltaic systems using rooftop resources. Recently, relevant policies prioritizing grid integration were introduced, requiring photovoltaic power generation to first solve the problem of self-consumption, encouraging residents and businesses to generate and consume their own electricity, and to feed surplus electricity into the grid. Pilot projects for two hundred zero-carbon industrial parks will also be carried out nationwide.

[0004] Currently, a few manufacturers have launched photovoltaic systems for different scenarios, among which photovoltaic tile systems are one type. This system is effectively integrated with traditional roof tile products, achieving the functions of both tiles and power supply to the load inside the house, while also supplying the surplus electricity to the power system. However, such photovoltaic tiles are extremely expensive and do not take into account the safety risks caused by snow sliding down, making them unsuitable for the use of most residential houses and fundamentally inconsistent with the intentions of the country's existing photovoltaic new energy policy.

[0005] To date, only a very small number of companies nationwide have begun research, development, production, and promotion of photovoltaic (PVT) integrated solar thermal panels. PVT panels are products that efficiently convert long, medium, and short wavelengths of light into both heat and electricity. This product achieves a conversion rate of over 80% for renewable solar energy, far exceeding the 20% conversion rate of photovoltaic tiles. Furthermore, by installing a solar thermal system, the probability of fires caused by photovoltaic hot spot effects is effectively reduced, completely avoiding the possibility of overturning fires on wooden roofs.

[0006] With the gradual improvement of national new energy policies, the photovoltaic industry has shifted from its previous irrational development to an orderly development driven by the principle of energy consumption. Although market investors have launched PVT systems, these are merely functional extensions of photovoltaic panel systems, with an excessive focus on aesthetics and durability, failing to realize the functionality of the watts, and neglecting the flexibility, universality, economy, and safety of the products in different scenarios.

[0007] Therefore, this application provides a combined solar power tile to meet the requirements. Summary of the Invention

[0028] like Figures 1 to 9 As shown, an embodiment of the present invention provides a combined photovoltaic tile, including: a photovoltaic tile body 1 and an energy-concentrating box body 8, wherein the photovoltaic tile body 1 and the energy-concentrating box body 8 are assembled into a combined photovoltaic tile, and the energy-concentrating box body 8 is disposed on the lower side of the photovoltaic tile body 1; The photovoltaic tile body 1 is assembled from the upper frame 2, the lower frame 3, the left frame 5, the right frame 4, and the photovoltaic panel 9; Upper frame 2, the upper frame 2 is set on the upper side of the photovoltaic tile body 1; The bottom frame 3 is located on the side of the photovoltaic tile body 1 away from the top frame 2; Left frame 5, the left frame 5 is set on the left side of the photovoltaic tile body 1; Right frame 4 is located on the side of left frame 5 away from photovoltaic tile body 1; Photovoltaic panel 9 is inserted into the slot of the upper frame 2 and bonded with flame-retardant neutral silicone adhesive; it is also bonded to the recessed groove of the lower frame 3 with flame-retardant neutral silicone adhesive; it is bonded to the groove of the left frame 5 away from the slot with flame-retardant neutral silicone adhesive; and it is placed on the upper side of the right frame 4 and bonded to the upper edge of the right frame 4 to prevent rainwater from flowing back. The energy-concentrating box body 8 is assembled from the energy-concentrating box outer frame, stainless steel coil 6 and flame-retardant rubber and plastic cotton. Stainless steel coil 6 is located inside the energy-concentrating box body 8, on the upper side of the flame-retardant rubber and plastic cotton. Rubber and plastic cotton 7 is set on the upper side of the bottom plate of the energy-concentrating box body 8 and located on the lower side of the stainless steel coil 6.

[0029] In this embodiment, as Figures 2 to 6 As shown, the dimensions of the upper frame 2 are L*48*(10-19.16)mm. The upper frame 2 is provided with a continuous protruding rib 17.5mm away from the upper edge. The upper side of the protruding rib has a width of 15.5mm, and the upper frame 2 is provided with a 1.5mm recessed anchoring groove.

[0030] In the above technical solution, the use of raised ribs can prevent rainwater backflow and ensure the positioning of the photovoltaic tiles. The recessed anchoring grooves can be used with special hooks to reliably anchor the photovoltaic tiles, thereby improving the stability of the installation and the ability to resist wind and snow slippage, while ensuring the structural strength and appearance of the frame.

[0031] In this embodiment, as Figures 1 to 2 As shown, a continuous raised rib is made at 17.5mm from the top edge of the 42mm border of the upper frame 2. The thickness of the raised rib is 1mm and the height is 4.16mm. A continuous slot is made 13mm from the bottom edge of the upper frame 2. The slot is 6mm wide, 1mm thick at the top, and 5mm between the top and bottom edges. The width from the bottom edge of the slot to the bottom edge of the upper frame 2 is 13mm.

[0032] In the above technical solution, the raised ribs can effectively prevent rainwater backflow and ensure the waterproof effect of the roof; and the slots provided along the lower edge can be used for overlapping sealing and structural connection, which can further prevent rainwater leakage, and at the same time form an overlapping splicing assembly structure, thereby improving the sealing and integrity of the combined installation of multiple photovoltaic tiles.

[0033] In this embodiment, as Figures 1 to 2As shown, the dimensions of the lower frame 3 are L*42*(5-13)mm. The lower edge of the lower frame 3 is 30mm wide and has a sloping edge. The thickness of the lower edge is 5mm. There are continuous raised ribs in the middle, with a height of 6.67mm. There are discontinuous rectangular drainage holes at the bottom of the middle ribs. The bottom edge of the bottom frame 3 has a hook with a width of 3mm on the back of the 30mm bottom edge, and the bottom edge of the bottom frame 3 has a groove with a height of 4mm and a width of 26mm, a hook, and a drip groove.

[0034] In the above technical solution, the sloping structure set in the lower frame 3 facilitates drainage, and the raised ribs set in the middle enhance the overall rigidity of the structure. The discontinuous drainage holes can promptly discharge infiltrated water, and the hooks and drip grooves set on the back enable the overlapping and hanging of photovoltaic tiles, achieving the effect of water stoppage and diversion, thereby preventing rainwater from entering the inner side of the roof and improving the overall waterproof and wind-resistant performance.

[0035] In this embodiment, as Figures 1 to 2 As shown, the shape of the left frame 5 is L-shaped, and the bottom length of the left frame 5 is longer than the vertical end. The size of the left frame 5 is B*10*20mm, and it is used to seal the overall frame connection.

[0036] In the above technical solution, by adopting this size for the left frame 5 of the L-shape, the side of the photovoltaic tile can be completely sealed using the left frame 5. This ensures both the sealing and strength of the side structure and the neat splicing of multiple photovoltaic tiles, thereby improving the aesthetics and sealing of the combined installation and preventing water and dust from entering from the side.

[0037] In this embodiment, as Figures 1 to 5 As shown, the dimensions of the right frame 4 are B*42mm*(9-25)mm. A trapezoidal drainage groove is provided on the right side of the right frame 4. The height of the trapezoidal drainage groove is 10mm. The height of the rectangular side of the trapezoidal drainage groove near the inner side of the photovoltaic tile body 1 is 23mm. The upper opening width of the groove is 27.5mm and the lower bottom width is 15mm. The right frame 4 has a continuous slot along the rectangular side. The slot is 7mm wide and 2mm thick at the top edge. The net distance between the top edge of the slot and the bottom edge of the trapezoidal water tank is 23mm. A semicircle with a radius of 1mm is opened at the port for sealing and water stop.

[0038] In the above technical solution, the trapezoidal drainage channel can quickly divert rainwater from the side, thereby preventing water accumulation and leakage; and the slot can be used for splicing positioning and sealing, and its semi-circular structure at the port can further improve the water-stopping and sealing effect, thus realizing the integration of overall side waterproofing, diversion and splicing.

[0039] In this embodiment, as Figures 3 to 6 As shown, the dimensions of the rubber and plastic cotton 7 are (L+25)mm*(B-20)mm*10mm. The inner side of the energy-concentrating box body 8 and the bottom plate are bonded to the rubber and plastic cotton 7 for heat preservation of the energy-concentrating box.

[0040] In the above technical solution, by using B1-grade flame-retardant rubber and plastic cotton 7 and fully covering and pasting it inside the energy-concentrating box body 8, the energy-concentrating box body 8 can achieve heat insulation and reduce heat loss, thereby improving heat recovery efficiency. At the same time, it has flame-retardant properties, thus improving overall fire safety.

[0041] In this embodiment, as Figures 1 to 6 As shown, the stainless steel coil 6 is a DN10mm 304 stainless steel tube, and the stainless steel coil 6 is bent into a coil inside the energy-concentrating box body 8. The stainless steel coil 6 passes through both ends of the bottom plate of the energy-concentrating box body 8, and both ends extend 35mm from the left and right outer edges of the energy-concentrating box body 8.

[0042] In the above technical solution, by using DN10mm 304 stainless steel pipe for the stainless steel coil 6, the waste heat from photovoltaic tile power generation and silicon wafer heat accumulation can be absorbed inside the energy-concentrating box body 8, and the heat can be recovered and the working temperature of the photovoltaic tile can be reduced through internal circulating water, thereby extending its service life; and the extended structure at both ends facilitates the series connection of pipelines between multiple photovoltaic tiles, enabling large-scale heat energy recovery and utilization.

[0043] In this embodiment, as Figures 1 to 2 As shown, the thickness of the photovoltaic tile body 1 is 15mm, and the thickness of the internal recess of the photovoltaic tile body 1 is 4mm. The front dimensions of the photovoltaic tile body 1 are L*B*15mm, and the dimensions of the recessed part of the front frame of the photovoltaic tile body 1 are (L-0)*(B-65)*4mm.

[0044] In the above technical solution, by setting a 4mm thick recess inside the photovoltaic tile body 1, it is possible to facilitate the bonding and installation of photovoltaic glass, thereby forming a regular installation surface and appearance effect, and at the same time facilitating the arrangement of frame sealing and waterproof structure.

[0045] In this embodiment, as Figures 3 to 6 As shown, the dimensions of the energy-concentrating box body 8 are (L-35)mm*(B-80)mm*30mm. The material of the energy-concentrating box body 8 is non-combustible metal. There are 60mm*10mm long holes on the left and right sides of the bottom plate of the energy-concentrating box body 8, 110mm away from the lower edge of the photovoltaic tile, to facilitate the installation of the stainless steel coil 6. There are two 10mm diameter round holes with a spacing of 50mm on the center line of the bottom plate of the energy-concentrating box body 8, 100mm away from the left edge, for the photovoltaic lines of the photovoltaic tile body 1 to be led out.

[0046] In the above technical solution, by using a non-combustible metal box body 8, the flame retardant performance of the energy-concentrating box body 8 can be improved, and it can be used to suppress the spread of fire when a fire occurs; by setting a junction box at the bottom of the energy-concentrating box body 8, and opening two round holes (such as...) inside the junction box at the bottom of the energy-concentrating box body 8... Figure 3 As shown in the figure, it can be used to lead out photovoltaic lines, thereby realizing the separate arrangement of photovoltaic and photothermal system lines and pipelines, and improving safety and installation standardization.

[0047] Working principle of the invention: By providing an upper frame 2, a lower frame 3, a right frame 4, and a left frame 5 around the photovoltaic tile body 1, it is easy to combine and install multiple photovoltaic tiles. Furthermore, the continuous raised ribs on the upper frame 2, located 17.5mm from the top edge, effectively prevent rainwater backflow and ensure the roof's waterproofing. The continuous slots along the lower edge allow for overlapping sealing and structural connection, further preventing rainwater leakage and forming an overlapping and splicing assembly structure, thus improving the sealing and overall integrity of the combined installation of multiple photovoltaic tiles. The sloping structure on the lower frame 3 facilitates drainage, and the raised ribs in the center further enhance this function. This design enhances the overall structural rigidity. Discontinuous drainage holes allow for timely removal of infiltrated water. Hooks and drip grooves on the back enable overlapping and mounting of the photovoltaic tiles, achieving a water-stopping and drainage effect, preventing rainwater from entering the roof interior and improving overall waterproofing and wind resistance. The L-shaped left frame 5, using this size, allows for complete sealing of the photovoltaic tile side, ensuring structural integrity and strength while enabling neat splicing of multiple tiles, thus improving the aesthetics and sealing of the installation and preventing water and dust ingress. The trapezoidal drainage channels quickly drain rainwater from the sides, preventing water accumulation. Water leakage is prevented; the slots allow for splicing positioning and sealing, and the semi-circular structure at the ports further enhances the water-stopping and sealing effect, thus achieving integrated side waterproofing, drainage, and splicing. By using B1-grade flame-retardant rubber-plastic cotton 7 and fully covering the interior of the energy-concentrating box body 8, the body achieves thermal insulation, reducing heat loss and improving heat recovery efficiency. It also possesses flame-retardant properties, enhancing overall fire safety. By using DN10mm 304 stainless steel tubing 6, the stainless steel coil 6 absorbs waste heat from photovoltaic tile power generation and silicon wafer heat accumulation within the energy-concentrating box body 8, and recovers and reduces heat through internal circulating water. The low operating temperature of the photovoltaic tiles extends their service life; the extended structures at both ends facilitate the series connection of multiple photovoltaic tiles, enabling large-scale heat recovery and utilization; the 4mm thick recess inside the photovoltaic tile body 1 facilitates the bonding and installation of photovoltaic glass, resulting in a neat installation surface and appearance, while also facilitating frame sealing and waterproofing; the use of a non-combustible metal casing for the energy-concentrating box body 8 improves its flame-retardant properties and can be used to suppress the spread of fire; a junction box is located at the bottom of the energy-concentrating box body 8, with two round holes (e.g., ...) inside the junction box at the bottom of the energy-concentrating box body 8. Figure 3 As shown in the figure, it can be used to lead out photovoltaic lines, thereby realizing the separate arrangement of photovoltaic and solar thermal system lines and pipelines, and improving safety and installation standardization; Furthermore, the photovoltaic tile body 1 and the energy-concentrating box body 8 can be assembled and used according to the actual environmental requirements of the application, as well as the photovoltaic tile body 1 can be used independently. The first usage method: When the photovoltaic tile body 1 and the energy-concentrating box body 8 are used in combination, the non-combustible metal energy-concentrating box body 8 is anchored and spliced ​​to the photovoltaic tile body 1 as a whole through the groove structure on the back of the photovoltaic tile body 1. The energy-concentrating box body 8 has a built-in stainless steel coil 6 and rubber and plastic cotton 7 to form a lower heat recovery unit. The heat-concentrating performance of the photovoltaic silicon wafer and the waste heat generated in the power generation process are used to recover heat through the circulating water in the stainless steel coil 6, thereby reducing the operating temperature of the photovoltaic module and extending its service life. The rubber and plastic cotton 7 provides thermal insulation and reduces heat loss. In the second usage method, when the photovoltaic tile body 1 is used alone, the energy-concentrating box body 8 is no longer installed. Instead, the upper frame 2, lower frame 3, right frame 4, and left frame 5 are assembled into the photovoltaic tile body 1. Photovoltaic components are installed inside the photovoltaic tile body 1, and only the photovoltaic power generation function is retained. Through the anchoring grooves, hooks, drainage grooves, slots, and other structures on the frame, the overlapping, fixing, drainage, and sealing of the roof tiles are achieved, meeting the requirements of waterproofing, wind resistance, snow slippage prevention, and aesthetics of traditional roof tiles.
