Description

Technical Field

[0001] This application relates to the field of photovoltaic tile installation, and in particular to a detachable installation structure for photovoltaic tiles that prevents dust accumulation and wind damage. Background Technology

[0002] With the continuous development of photovoltaic technology, photovoltaic tiles, as a product that combines power generation and architectural aesthetics, have gradually attracted market attention. However, existing photovoltaic tile installation structures have many problems, limiting their widespread application.

[0003] An existing patent, CN112671314A, describes a concealed bottom mounting structure for photovoltaic tile roofing. This structure includes a mounting component installed on the tile strip and corresponding to the upper edge of the photovoltaic tile, and a lower frame positioned on the lower edge of the photovoltaic tile and capable of engaging with the mounting component. The mounting component comprises a fixing base, a connecting portion, and a groove portion. The fixing base connects to the tile strip, the connecting portion forms a replacement space to accommodate the upper edge of the corresponding photovoltaic tile, and the groove portion forms a groove for mounting the lower frame. The fixing base and the groove portion are respectively connected to both sides of the connecting portion. The lower frame includes an mounting portion and a mounting portion. The mounting portion forms a glass groove to accommodate the lower edge of the photovoltaic tile, and the mounting portion forms a hook for engaging with the groove. This invention has a simple structure, is easy to install, and can simultaneously achieve photovoltaic tile mounting and wind-resistant installation, reducing installation costs and improving installation efficiency.

[0004] The existing technology mentioned above integrates a hanging structure on the lower frame, which has a high overall material cost. Furthermore, the A-side structure of the lower frame is prone to the accumulation of mud and sand, forming "hot spots" that affect the power generation and lifespan of the photovoltaic tiles.

[0005] An existing patent, CN112583332A, describes a mounting structure for installing photovoltaic (PV) roof tiles. This structure includes a mounting component installed on a tile strip and corresponding to the upper edge of the PV tile, and a lower frame positioned on the lower edge of the PV tile and capable of engaging with the mounting component. The mounting component includes a fixing base, a connecting portion, and a hook portion. The fixing base connects to the tile strip, the connecting portion forms a space to accommodate the upper edge of the corresponding PV tile, and the hook portion forms a hook for attaching to the lower frame. The lower frame includes an mounting portion and a hooking portion. The mounting portion forms a glass groove to accommodate the lower edge of the PV tile, and the hooking portion forms a hanging hole for attaching the hook. This invention has a simple structure, is easy to install, and can simultaneously achieve PV tile mounting and wind-resistant installation, reducing installation costs and improving installation efficiency.

[0006] The aforementioned existing technologies have not solved the problem of dust accumulation on the front of photovoltaic tiles and still face the risk of "hot spots," affecting the power generation and service life of photovoltaic tiles. If the mounting holes on the B-side of the frame are not adequately treated with anti-corrosion measures (such as anodizing or coating), localized corrosion may occur due to rainwater penetration, affecting the lifespan and structural strength of the frame. The matching of the mounting holes on the B-side of the frame with the hooks requires high precision. If there are dimensional deviations during on-site installation (such as offset of the mounting hole position or angle error), it may lead to installation failure or insufficient stability. Opening holes on the B-side of the frame increases processing costs. Utility Model Content

[0007] In order to overcome the problems existing in the prior art, this application provides a detachable installation structure for photovoltaic tiles that prevents dust accumulation and wind upsetting.

[0008] The detachable installation structure for photovoltaic tiles that prevents dust accumulation and wind uplift provided in this application adopts the following technical solution:

[0009] A detachable installation structure for photovoltaic tiles that prevents dust accumulation and wind upsetting includes a base and photovoltaic tiles. The base is used to fix and connect to the tile hanger strip. The lower frame of the photovoltaic tile supports the photovoltaic tile from below. The base and the lower frame are locked together by a hook. The base adopts a U-shaped structure, with one end of the base connected to the tile hanger strip by a self-tapping screw and the other end of the base using a U-shaped hook. The lower frame includes a main body. The top surface of the main body is used to support the photovoltaic tile, and a baffle of the same height as the photovoltaic tile is provided on the side away from the photovoltaic tile. A receiving groove extends outward from the bottom of the side of the main body away from the baffle. The main body, the baffle, and the receiving groove are integrally formed. The hook adopts a U-shaped mechanism. The inside of one side of the hook fits against the outside of the baffle of the lower frame, and the other end of the hook uses an L-shaped hook that hooks with the U-shaped hook.

[0010] By adopting the above technical solution, one end of the base is first fixed to the roof strip with self-tapping screws. When installing the photovoltaic tile, the upper part of the photovoltaic tile rests on the roof strip above, and the main body of the lower frame supports the photovoltaic tile. The receiving groove of the lower frame is then positioned accordingly. Next, the inside of one side of the hook is attached to the outside of the lower frame baffle, and then the L-shaped hook at the other end of the hook is hooked to the U-shaped hook of the base. This achieves the locking of the base and the lower frame through the hook, and the photovoltaic tile is securely installed. This structure is convenient for disassembly and assembly, and can effectively prevent dust accumulation and resist wind damage.

[0011] Preferably, the photovoltaic tile includes a photovoltaic laminate, which is glued to the left frame, right frame and bottom frame. The bottom frame is connected to the left frame and right frame by a corner bracket. The bottom frame is provided with a lower water-blocking strip. The surface of the photovoltaic laminate away from the lower water-blocking strip is provided with an upper water-blocking strip. A junction box is also installed on the back of the photovoltaic laminate.

[0012] Preferably, a lower water-blocking strip is installed below the lower frame, the opening of the receiving groove on the lower frame faces downward, and the lower water-blocking strip is located in the receiving groove and connected to the inner bottom surface of the hook.

[0013] Preferably, an upper water-blocking strip is provided on the side of the photovoltaic laminate surface away from the lower water-blocking strip, wherein the upper water-blocking strip is located within the space enclosed by the base and the hook.

[0014] By adopting the above technical solution, the photovoltaic laminate of the photovoltaic tile is firmly connected to the left, right, and bottom frames via adhesive. The bottom frame is further reinforced with corner brackets to achieve precise positioning and connection with the left and right frames, forming a stable frame. The lower water-blocking strip within the recessed area below the bottom frame connects to the inner bottom surface of the support hook, effectively blocking rainwater from entering from the bottom. The upper water-blocking strip on the surface of the photovoltaic laminate, located within the space enclosed by the base and the support hook, intercepts rainwater from above. The upper and lower water-blocking strips work together to form a double waterproof barrier. Simultaneously, the junction box on the back of the photovoltaic laminate ensures circuit connection and power transmission. All components cooperate to ensure both the structural stability of the photovoltaic tile and efficient waterproofing and normal power generation.

[0015] Preferably, the connection end between the base and the batten strip is also equipped with an L-shaped connector, which fits against the top and side surfaces of the batten strip, with self-tapping screws located on both sides of the connection between the base and the L-shaped connector.

[0016] Preferably, the width of the base is smaller than the width of the hook, and the hook is always connected to the lower frame through the lower water-blocking strip during its movement along the length of the lower frame.

[0017] Preferably, the top of the main body of the lower frame has several strip-shaped grooves evenly distributed along its length.

[0018] By adopting the above technical solution, the L-shaped connector installed at the connection end between the base and the tile strip, through its tight fit with the top and sides of the tile strip, and the self-tapping screws on both sides of the connection between the base and the L-shaped connector, greatly enhances the stability and firmness of the connection between the base and the tile strip. The width of the base is smaller than the width of the hook, allowing the hook to move along the length of the lower frame, and maintaining connection with the lower frame through the lower water-blocking strip during the movement, ensuring both installation flexibility and the integrity of the waterproof structure. The evenly distributed strip-shaped grooves on the top of the lower frame increase the contact area with the photovoltaic laminate, and also facilitate better adhesion of adhesives or other fixing materials, further improving the overall stability of the photovoltaic tile installation and ensuring reliable operation even in complex environments.

[0019] Preferably, building tiles are installed on the upper and lower sides of the photovoltaic tile as a whole, with one end of the building tile fixedly installed on the roof.

[0020] By adopting the above technical solution, architectural tiles are installed on the upper and lower sides of the photovoltaic tiles, with one end of the architectural tile firmly fixed to the roof. This fixing provides additional protection and support for the photovoltaic tiles. On one hand, the architectural tile protects the photovoltaic tiles from impacts by external debris, reducing the risk of physical damage; on the other hand, its close fit with the photovoltaic tiles fills gaps at the edges, enhancing overall waterproofing performance. Simultaneously, it optimizes the roof appearance, allowing the photovoltaic system to better integrate with traditional building roofs, balancing functionality and aesthetics, and improving the overall performance of the roof system.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. This application separates the base, hook and lower frame design to avoid the lower frame integrated hanging structure, effectively reducing the overall material cost. The lower frame is designed to support the main body at the top and block the photovoltaic laminate on the side, making it difficult for mud and sand to accumulate, reducing the formation of "hot spots", and ensuring the power generation efficiency and service life of the photovoltaic tile.

[0023] 2. This application avoids opening holes in the frame, thus eliminating a series of problems that may be caused by opening holes, such as corrosion prevention, processing costs, and installation accuracy.

[0024] 3. This application enhances the connection stability by using an L-shaped connector at the connection end between the base and the batten strip and self-tapping screws on both sides. The difference in width between the base and the hook and the connection design allow the hook to move flexibly while ensuring waterproofing.

[0025] 4. The U-shaped base in this application is matched with the U-shaped hook at its end, and the U-shaped support hook and the L-shaped hook at its end are matched to fix the photovoltaic tile and achieve the function of resisting wind uplift, thereby enhancing the stability and reliability of the structure.

The base 1 is used to fix and connect to a tile hanger 3. The lower frame 21 of the photovoltaic tile 2 supports the photovoltaic tile 2 from below. The base 1 and the lower frame 21 are locked together by a hook 4.

The lower frame 21 includes a main body 211, with the main body 211 topped with... A baffle 212 of the same height as the photovoltaic tile 2 is provided on the side of the main body 211 that is away from the baffle 212. A receiving groove 213 extends outward from the bottom of the main body 211 on the side away from the baffle 212. The main body 211, the baffle 212 and the receiving groove 213 are integrally formed. The hook 4 adopts a U-shaped mechanism. The inside of one side of the hook 4 is attached to the outside of the baffle 212 of the lower frame 21. The other end of the hook 4 adopts an L-shaped hook 41, and the L-shaped hook 41 is hooked to the U-shaped hook 12. First, fix one end of the base 1 to the tile strip 3 with self-tapping screws 11. When installing the photovoltaic tile 2, the upper part of the photovoltaic tile 2 rests on the upper tile strip 3, and the top surface of the main body 211 of the lower frame 21 supports the photovoltaic tile 2. The receiving groove 213 of the lower frame 21 is then in place. Next, the inside of one side of the hook 4 is attached to the outside of the baffle 212 of the lower frame 21. Then, the L-shaped hook 41 at the other end of the hook 4 is hooked to the U-shaped hook 12 of the base 1, thereby locking the base 1 and the lower frame 21 together with the hook 4 and securely installing the photovoltaic tile 2. This structure is convenient for disassembly and assembly, and can effectively prevent dust accumulation and resist wind damage.

[0035] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The photovoltaic tile 2 includes a photovoltaic laminate 22, which is glued to the left frame 23, right frame 24, and lower frame 21. The lower frame 21 is connected to the left frame 23 and right frame 24 via corner brackets 25. The lower frame 21 has a lower water-blocking strip 26, and the photovoltaic laminate 22 has an upper water-blocking strip 27 on the side away from the lower water-blocking strip 26. A junction box 28 is also installed on the back of the photovoltaic laminate 22. The lower water-blocking strip 26 is installed below the lower frame 21, and the receiving groove 213 on the lower frame 21 opens downward. The lower water-blocking strip 26 is located inside the receiving groove 213 and connected to the inner bottom surface of the support hook 4. The upper water-blocking strip 27 is located on the side of the photovoltaic laminate 22 away from the lower water-blocking strip 26, and the upper water-blocking strip 27 is located within the space enclosed by the base 1 and the support hook 4. The photovoltaic laminate 22 of the photovoltaic tile 2 is securely connected to the left frame 23, right frame 24, and bottom frame 21 by adhesive. The bottom frame 21 is further precisely positioned and reinforced with the left and right frames 24 by corner brackets 25, forming a stable frame. The lower water-blocking strip 26, located in the groove 213 below the bottom frame 21, is connected to the bottom surface of the support hook 4, effectively blocking rainwater from entering from the bottom. The upper water-blocking strip 27 on the surface of the photovoltaic laminate 22 is located within the space enclosed by the base 1 and the support hook 4, intercepting rainwater from above. The upper and lower water-blocking strips 26 work together to form a double waterproof barrier. At the same time, the junction box 28 on the back of the photovoltaic laminate module ensures circuit connection and power transmission. All components work together to ensure the structural stability of the photovoltaic tile 2, while also achieving efficient waterproofing and normal power generation.

[0036] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The base 1 and the connecting end of the batten strip 3 are also equipped with an L-shaped connector 13. The L-shaped connector 13 fits against the top and side surfaces of the batten strip 3, and the self-tapping screws 11 are located on both sides of the connection between the base 1 and the L-shaped connector 13. The width of the base 1 is smaller than the width of the hook 4, and the hook 4 is always connected to the lower frame 21 via the lower water-blocking strip 26 during its movement along the length of the lower frame 21. The top of the main body 211 of the lower frame 21 has several strip-shaped grooves 214 evenly distributed along its length. The L-shaped connector 13 installed at the connection end between the base 1 and the tile strip 3, by tightly fitting with the top and sides of the tile strip 3, and in conjunction with the self-tapping screws 11 on both sides of the connection between the base 1 and the L-shaped connector 13, greatly enhances the stability and firmness of the connection between the base 1 and the tile strip 3. The width of the base 1 is smaller than the width of the hook 4, allowing the hook 4 to move along the length of the lower frame 21, and during the movement, it always maintains a connection with the lower frame 21 through the lower water-blocking strip 26, which ensures both the flexibility of installation and the integrity of the waterproof structure. The strip-shaped grooves 214 evenly distributed on the top of the main body 211 of the lower frame 21 increase the contact area with the photovoltaic laminate 22, and also facilitate better adhesion of adhesives or other fixing materials, further improving the overall stability of the photovoltaic tile 2 installation and ensuring reliable operation even in complex environments.

[0037] Reference Figure 2 Building tiles 5 are installed on the upper and lower sides of the photovoltaic tile 2, with one end of the building tile 5 fixedly installed on the roof 6. The building tiles 5 provide additional protection and support for the photovoltaic tile 2. On one hand, the building tiles 5 protect the photovoltaic tile 2 from impacts from external debris, reducing the risk of physical damage; on the other hand, they fit tightly with the photovoltaic tile 2, filling gaps at the edges and enhancing overall waterproofing. Simultaneously, they optimize the appearance of the roof 6, allowing the photovoltaic system to better integrate with the traditional building roof 6, balancing functionality and aesthetics, and improving the overall performance of the roof 6 system.

[0038] Working principle: When the detachable installation structure of the anti-dust and wind-blown photovoltaic tile 2 is in operation, the base 1 is first fixed to the tile hanging strip 3 through the L-shaped connector 13. The L-shaped connector 13 fits against the top and sides of the tile hanging strip 3, and a stable connection is achieved with the self-tapping screws 11 on both sides. When installing the photovoltaic tile 2, the photovoltaic laminate 22 is connected to the left and right side frames 24 and the lower frame 21 by applying glue. The lower frame 21 is reinforced and connected to the left and right side frames 24 through the corner bracket 25 to form a stable frame. The lower water-blocking strip 26 in the receiving groove 213 is connected to the inner bottom surface of the hook 4. The upper part of the assembled photovoltaic tile 2 rests on the upper hanging strip 3, while the top surface of the main body 211 of the lower frame 21 supports the photovoltaic tile 2. The receiving groove 213 of the lower frame 21 is then positioned accordingly. Next, the inside of one side of the hook 4 is fitted against the outside of the baffle 212 of the lower frame 21, and then the L-shaped hook 41 at the other end of the hook 4 is hooked to the U-shaped hook 12 of the base 1. The width of the hook 4 is greater than that of the base 1, allowing it to move along the length of the lower frame 21. During movement, the connection and waterproofing are maintained by the lower water-blocking strip 26. At the same time, the upper water-blocking strip 27 on the surface of the photovoltaic laminate 22 is located within the space enclosed by the base 1 and the hook 4, forming a double waterproofing with the lower water-blocking strip 26 to prevent rainwater intrusion. The strip-shaped groove 214 on the top of the main body 211 of the lower frame 21 increases the contact area with the photovoltaic laminate 22, improving the fixing effect. Finally, building tiles 5 are installed on the top and bottom sides of the photovoltaic tile 2, with one end fixed to the roof 6. This protects the photovoltaic tile 2, fills gaps to enhance waterproofing, and optimizes the appearance of the roof 6. All components work together to achieve stable installation of the photovoltaic tile 2, efficient waterproofing and dust prevention, and improve power generation efficiency and service life.

[0039] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
