Description

Technical Field

[0001] The present invention belongs to the field of photovoltaic tiles, and in particular to an integrated molded photovoltaic tile frame, a method for preparing the photovoltaic tile frame, and a photovoltaic tile. Background Art

[0002] With the continuous development of solar energy utilization technology, the performance and installation method of photovoltaic tile frames, as a key structure supporting and fixing photovoltaic modules, directly affect the stability and service life of photovoltaic systems. Traditional photovoltaic tile frames are mostly installed individually, which has many drawbacks when facing complex and changing natural environments.

[0003] In windy conditions, a single tile frame installed directly on the roof makes it difficult to evenly distribute wind forces. Excessive localized stress can easily cause the tile frame to loosen, shift, or even damage, resulting in poor wind resistance and severely impacting the safety and reliability of the photovoltaic system in inclement weather. Furthermore, traditional photovoltaic tile frames lack a scientific and rational drainage design for rooftop drainage, failing to effectively accommodate varying roof slopes and drainage requirements. During rainy weather, rainwater easily accumulates on the roof, even causing backflow. This not only erodes the roof but can also damage indoor facilities, significantly shortening the lifespan of the roof and the photovoltaic tile frame.

[0004] Furthermore, existing photovoltaic tile frame production methods have limitations in material selection and processing techniques. Some traditional methods employ materials that fail to balance cost and performance. For example, some materials lack strength, making the resulting photovoltaic tile frames unable to withstand the forces of complex environments. Meanwhile, some high-strength materials and production costs are prohibitive, hindering large-scale deployment. Furthermore, material ratios are often not rationally balanced, hindering the full potential of each material, impacting the quality and stability of photovoltaic tile frame products.

[0019] Preferably, in step S1, the reinforcing fibers are composed of one or more of basalt fibers, carbon fibers, and glass fibers.

[0020] The present invention also provides a photovoltaic tile, comprising a photovoltaic chip and the above-mentioned photovoltaic tile frame.

[0021] The beneficial effects of the present invention are as follows:

[0022] 1. The integrated molded photovoltaic tile frame, photovoltaic tile frame preparation method, and photovoltaic tile described herein achieve secure installation on the roof through the tight fit of screws and fixing holes. Multiple tile frame bodies are assembled side by side to form a monolithic tile frame structure. In windy weather, wind force is evenly distributed throughout the structure, and each tile frame body is jointly subjected to force, effectively resisting wind damage. Compared with traditional single tile frame installation methods, this greatly reduces the risk of loosening, displacement, and damage caused by wind, improving safety and reliability in inclement weather.

[0023] 2. The integrated molded photovoltaic tile frame, photovoltaic tile frame preparation method, and photovoltaic tiles described in this invention are assembled side by side and tilted on the roof, depending on the roof slope and drainage requirements. The drainage grooves on the top connecting blocks of the highest photovoltaic tile frame and the grooves on the top of the right connecting block of the rightmost parallel photovoltaic tile frame together form a continuous drainage channel, which can drain rainwater in an orderly manner on rainy days, preventing rainwater accumulation and backflow on the roof, protecting the roof and indoor facilities, and extending the service life of the roof and photovoltaic tile frame.

[0024] 3. The one-piece molded photovoltaic tile frame, photovoltaic tile frame preparation method and photovoltaic tile described in the present invention, the upper photovoltaic tile frame can block the lower fixing hole, reduce the contact of the screws with adverse environmental factors such as moisture and corrosive gases in the air, protect the fixing parts, ensure its good fixed installation effect, and improve the stability and durability of the overall structure of the photovoltaic tile frame.

[0025] 4. The integrated molded photovoltaic tile frame, photovoltaic tile frame preparation method, and photovoltaic tile described in this invention address the problem of water seepage caused by aging of traditional sealing methods. A drainage channel and a drain outlet are provided on the inner bottom wall of the glass chip mounting groove. If the sealant or rubber gasket ages and leaks, the seeped water flows into the drainage channel and is discharged through the drain outlet, preventing water accumulation and damage to the photovoltaic system. Furthermore, the drainage channel is located below the photovoltaic tile to prevent debris such as fallen leaves from entering, preventing blockage in the channel and outlet, and ensuring continuous and stable drainage.

[0026] 5. The integrally molded photovoltaic tile frame, its preparation method, and the photovoltaic tile described herein feature a reinforcement assembly comprised of a horizontal and diagonal reinforcement frame within the main body of the tile frame, enhancing the structural strength of the main frame. After installation, the top of the reinforcement assembly tightly contacts the bottom wall of the tile, providing stable auxiliary support and distributing pressure on the tile, preventing cracks caused by uneven localized force. This improves the overall structural strength of the tile frame and the stability of the photovoltaic tile, minimizing the impact of sway and displacement on performance.

[0027] 6. The one-piece molded photovoltaic tile frame, photovoltaic tile frame preparation method and photovoltaic tile described in the present invention, after the photovoltaic tile is installed in the glass chip mounting groove, the photovoltaic tile is reinforced by inserting the reinforcement pin into the pin opening until its side wall is tightly against the side wall of the photovoltaic tile to prevent it from falling off from the glass chip mounting groove.

[0028] 7. The integrated molded photovoltaic tile frame, photovoltaic tile frame preparation method, and photovoltaic tile described in the present invention utilize a scientific material ratio, including polyester resin, modified polypropylene, calcium hydroxide, reinforcing fiber, inorganic powdered filler calcium carbonate powder or rock powder, and reasonable processing steps, such as uniform stirring, addition of release agent and curing agent, and high-temperature compression molding, to produce photovoltaic tile frame products that meet performance requirements. The reinforcing fiber is composed of one or more of basalt fiber, carbon fiber, and glass fiber, and can be adjusted according to actual needs to provide the photovoltaic tile frame with good structural performance and ensure product quality and stability.

[0037] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0038] like Figures 1 to 6 As shown, the one-piece molded photovoltaic tile frame of the embodiment of the present invention includes a tile frame body 1 and a glass chip mounting groove 11. The top of the tile frame body 1 is provided with a glass chip mounting groove 11, and the glass chip mounting groove 11 is used for installing photovoltaic chips. The inner bottom wall of the glass chip mounting groove 11 is provided with a drainage channel 12, and the bottom wall at the front end of the drainage channel 12 is provided with a drainage port 16. Pin holes 13 are provided on both sides and the side walls of the glass chip mounting groove 11. The rear end of the tile frame body 1 is fixed with a rear support plate 2, and the rear end of the rear support plate 2 is provided with a drainage ditch 17, and a fixing hole 3 is provided in the drainage ditch 17. The rear end of the top of the tile frame body 1 is fixed with a connecting block 14, and the front end of the connecting block 14 is provided with a side groove 41. The front end of the bottom of the tile frame body 1 is fixed with a connecting block 2 43. The right side of the tile frame body 1 is fixed with a connecting block 3 5, and the top of the connecting block 3 5 is provided with a card slot 51. The left side of the bottom of the tile frame body 1 is fixed with a connecting block 4 6.

[0039] The second connecting block 43 is L-shaped. The size of the second connecting block 43 matches the size of the side groove 41 , and the second connecting block 43 can be inserted into the inside of the side groove 41 .

[0040] There are multiple fixing holes 3 , which are opened at the rear end of the rear support plate 2 at equal intervals.

[0041] A drainage groove 42 is provided on the top of the connecting block 1 4 , and a clamping groove 51 is provided on the top of the connecting block 3 5 .

[0042] The cross-section of the connecting block three 5 and the card slot 51 is F-shaped, and the cross-section of the connecting block four 6 is F-shaped. The F-shaped structure composed of the connecting block three 5 and the card slot 51 can match and be connected with the F-shaped structure of the connecting block four 6.

[0043] Two reinforcing cross frames 14 are fixed to both ends of the interior of the tile frame body 1 , and a cross-arranged reinforcing oblique frame 15 is fixed between the two reinforcing cross frames 14 .

[0044] The top of the tile frame body 1 is provided with a water and dust proof edge 7 on one side away from the rear support plate 2. The top of the water and dust proof edge 7 is lower than the top of the two adjacent outer frames. The purpose of this design is to prevent dust and water accumulation, which can effectively improve the utilization rate of photovoltaic tiles.

[0045] Specifically, when installing the photovoltaic tile frame, the first step is to assemble the required number of tile frame bodies 1 side by side. The assembly process is as follows: First, place a tile frame body 1 at the predetermined required position. The determination of this position needs to be based on the overall layout of the roof and the planned installation plan of the photovoltaic tile frame to ensure the accuracy and stability of the subsequent installation. Then, align the connection block four 6 on the left side of the bottom of the second tile frame body 1 with the connection block three 5 on the right side of the top of the first tile frame body 1 so that the two are tightly snapped together. At this point, the side-by-side splicing operation of the two tile frame bodies 1 is completed. Subsequently, it is only necessary to repeat the above operation continuously to gradually assemble multiple tile frame bodies 1 side by side and finally form a row of photovoltaic tile frames. During this process, the installer needs to carefully check each snap connection to ensure that the connection is tight and avoid looseness or misalignment, so as not to affect the overall stability and functionality of the subsequent photovoltaic tile frame.

[0046] Then comes the installation and fixing phase. The installer needs to select suitable screws and fit them tightly with the fixing holes 3 on the tile frame body 1, so that a group of photovoltaic tile frames that have been arranged side by side can be firmly installed on the predetermined required position on the roof. After completing the installation of the first group, the second group of photovoltaic tile frames arranged side by side will be placed on top of the first group of photovoltaic tile frames arranged side by side. At this time, the connecting block 2 43 at the bottom front end of the second group of photovoltaic tile frames arranged side by side should be inserted into the side groove 41 opened at the front end of the connecting block 1 4 at the top rear end of the first group of photovoltaic tile frames arranged side by side, so as to complete the overlapping operation of the two groups of photovoltaic tile frames arranged side by side. Afterwards, use the screws to match the fixing holes 3 again, and according to the same operating specifications and tightening force requirements, firmly fix the overlapped second group of photovoltaic tile frames on the roof. At this point, the parallel stacking operation of the two groups of photovoltaic tile frames arranged side by side is successfully completed. For specific installation effects, please refer to Figure 5Throughout the installation process, whether securing a single PV tile frame or connecting and securing two sets of PV tile frames, the installer must strictly follow the operating procedures to ensure that each step is executed in place, laying a solid foundation for the stable operation of the PV tile frames. Repeating the above steps can complete the parallel assembly of multiple sets of PV tile frames.

[0047] The installation design of multiple photovoltaic tile frames has significant advantages and features. On the one hand, they not only achieve a firm installation on the roof through the close cooperation of screws and fixing holes 3, but also ensure stability in various natural environments. On the other hand, multiple tile frame bodies 1 are assembled side by side to form an integral tile frame structure. This design shows excellent wind resistance in the face of strong winds. When strong winds come, the photovoltaic tile frames assembled with multiple tile frame bodies 1 can jointly withstand the effects of wind. Compared with the traditional method of directly installing a single tile frame body 1 on the roof, this type of integral assembly design enables the wind to be evenly dispersed throughout the photovoltaic tile frame structure. The various tile frame bodies 1 cooperate with each other and bear the force together, so that they can better resist the invasion of wind, effectively reducing the risk of loosening, displacement or even damage of the photovoltaic tile frame due to wind, and greatly improving the safety and reliability of the photovoltaic tile frame under severe weather conditions.

[0048] When multiple photovoltaic tile frames are actually installed, they will be assembled side by side or in parallel according to the slope of the roof and the drainage requirements, and will be tilted on the roof. The specific installation form can be referred to Figure 6 As shown. The connection blocks 1-4 at the top of a group of photovoltaic tile frames assembled side by side at the highest position will be connected side by side, and the drainage grooves 42 on the top of these connection blocks 1-4 will naturally combine to form a coherent drainage channel, whose main function is to drain water efficiently. At the same time, a slot 51 is specially provided on the top of the connection block 3-5 fixed on the right side of the photovoltaic tile frame assembled side by side on the far right. This slot 51 can also be used as a drainage channel to participate in the drainage work. In actual use scenarios, if it rains, rainwater will naturally fall on the tile frame body 1. Since the photovoltaic tile frame is set at an angle, the rainwater will flow smoothly from the tile frame body 1 at the higher position to the tile frame body 1 at the lower position under the action of gravity. The rainwater will be discharged in an orderly manner through the drainage channel composed of the drainage groove 42 of the top connection block 1-4 and the slot 51 of the right connection block 3-5. This scientific and reasonable drainage design can effectively prevent rainwater from accumulating on the roof and avoid the problem of rainwater backflow, thereby protecting the roof and indoor facilities from rainwater erosion and extending the service life of the roof and photovoltaic tile frame.

[0049] In addition, the photovoltaic tile frames have a thoughtful protective design when stacked side by side. The photovoltaic tile frame located above will cleverly block the fixing hole 3. This design prevents the screws placed in the fixing hole 3 from being directly exposed to the air. In daily use, factors such as moisture and corrosive gases in the air will corrode the screws, which may affect the fastening performance of the screws over time. The shielding of the fixing hole 3 by the upper photovoltaic tile frame can reduce the contact between the screws and adverse external environmental factors to a certain extent, effectively protect the fixing parts, ensure that they always maintain a good fixed installation effect, and further improve the stability and durability of the overall structure of the photovoltaic tile frame.

[0050] Furthermore, during the construction of the photovoltaic system, the photovoltaic tiles are installed inside the glass chip mounting groove 11. In order to ensure the sealing of the photovoltaic tile installation, it is usually adopted to apply sealant around the photovoltaic tiles or set rubber gaskets. However, this type of sealing method has a disadvantage that cannot be ignored: as time goes by, after long-term exposure to wind and sun, and drastic changes in temperature and humidity, the sealant or rubber gasket is very likely to age. Once aging occurs, the sealing around the photovoltaic tiles will be greatly reduced, which will lead to water seepage problems. Water seepage may not only cause a short circuit in the internal circuit of the photovoltaic tile, affecting the power generation efficiency, but in severe cases it may even damage the entire chip, greatly shortening the service life of the photovoltaic system.

[0051] To address this issue, multiple tile frame bodies 1 are spliced together according to design requirements. The specific splicing method is as follows: two tile frame bodies 1 are overlapped, and the drainage ditch 17 on the top of the lower tile frame body 1 is aligned and connected with the drainage port 16 of the upper tile frame body 1. At this time, the drainage channel 12 is connected to the drainage ditch 17 through the drainage port 16. When it rains, the rainwater flows from the drainage channel 12 of the upper tile frame body 1 and flows into the drainage ditch 17 on the top of the lower tile frame body 1 through the drainage port 16. The drainage ditch 17 drains the rainwater, thus completing the drainage operation. In this way, even if the sealant or rubber gasket around the photovoltaic glass chip has a water seepage problem due to aging, the water that seeps in from around the photovoltaic glass chip will be discharged, thereby achieving the goal of removing the infiltrated rainwater and other water sources, and avoiding the damage of accumulated water to the photovoltaic system.

[0052] It's particularly noteworthy that, after the photovoltaic tiles are successfully installed within the glass chip mounting slots 11, the drain channel 12 lies directly beneath them. This ingenious layout offers an additional advantage: daily debris, such as fallen leaves, tends to accumulate on top of the tiles, rarely falling into the drain channel 12 or drain outlet 16, fundamentally eliminating the potential for blockage caused by debris accumulation. This ensures that the drain channel 12 and drain outlet 16 remain unobstructed at all times, preventing debris from interfering with drainage efficiency. This allows them to continuously and stably perform their drainage function, providing a solid foundation for the stable operation of the photovoltaic system.

[0053] It is further explained that the reinforcing cross frame 14 and the reinforcing diagonal frame 15 form a reinforcement component which is arranged inside the tile frame body 1. Just like the steel beams in a building, it plays a vital role in the tile frame structure, and its main function is to enhance the structural strength of the tile frame body 1. In actual application scenarios, after the photovoltaic tiles are installed inside the glass chip mounting groove 11, weather-resistant structural adhesive is added to the top of the component to bond it to the photovoltaic glass chip in the glass chip mounting groove 11. The reinforcement component plays the role of auxiliary support for the photovoltaic glass chip, effectively dispersing the pressure on the photovoltaic tiles, and avoiding cracks and the like due to local uneven force, thereby greatly improving the overall structural strength of the tile frame body 1, and at the same time significantly improving the stability of the photovoltaic tiles installed in the glass chip mounting groove 11, so that the photovoltaic tiles can maintain a stable state in the working environment and reduce performance interference caused by shaking and displacement.

[0054] Furthermore, the glass chip mounting groove 11 at the top of the tile frame body 1 is used to install photovoltaic tiles. After the photovoltaic tiles are installed into the glass chip mounting groove 11, the reinforcement pin is inserted into the pin hole 13 until the side wall of the reinforcement pin is tightly against the side wall of the photovoltaic tile. The photovoltaic tiles can then be reinforced with the reinforcement pin to better stabilize the photovoltaic tiles installed in the glass chip mounting groove 11 and prevent them from falling off. It should be noted that after the reinforcement pin is inserted into the pin hole 13, a weather-resistant structural adhesive can be used for bonding to ensure that the reinforcement pin can be fixed in the pin hole 13 and at the same time, ensure the connection between the reinforcement pin and the photovoltaic glass chip.
