Abstract
Description
Technical Field
[0001] This application relates to the field of photovoltaic roofing system technology, and more specifically, to a novel coated metal tile roofing photovoltaic system. Background Technology
[0002] In the existing field of building materials and photovoltaic roofing systems, there are many problems with installing photovoltaic systems on exposed polymer roll roofs.
[0003] One traditional installation method involves installing a vertical support, which is anchored to the inner corrugated steel sheet or purlin, and the photovoltaic system is fixed to the vertical support. However, this method requires penetrating the waterproof membrane layer, which will damage the original waterproof structure of the roof. This not only makes the construction process complicated and increases the construction cost, but also poses a serious risk of water leakage and high maintenance costs in the later stage.
[0004] Another method is to use lightweight structural adhesive to bond the components. However, the lifespan of the adhesive is difficult to match the lifespan of the photovoltaic system, and the adhesive is prone to aging and failure, which will increase the cost of secondary maintenance and may even lead to the detachment and damage of a large number of components, posing a great risk to the stable operation of the photovoltaic system.
[0005] Therefore, there is an urgent need for a new type of photovoltaic roofing system with coated metal tiles that can avoid damaging the roof waterproofing layer, is easy to install, has a stable structure, and is cost-effective.
[0006] Therefore, this application proposes a novel photovoltaic system for coated metal tile roofs to solve the aforementioned problems.
[0007] Application content
[0008] To address the aforementioned issues, this application provides a novel photovoltaic system for coated metal tile roofs.
[0009] The novel photovoltaic system for coated metal tile roofing provided in this application adopts the following technical solution:
[0010] A novel photovoltaic system for coated metal tile roofing includes:
[0011] A corrugated support, wherein multiple corrugated supports are provided and connected to the corrugated surface of the coated metal tile by welding;
[0012] A guide rail is detachably connected to the upper end of the corrugated support. The guide rail and the corrugations of the coated metal tile are arranged in a cross shape. A photovoltaic module is provided on the upper surface of the guide rail. A connecting component is detachably connected to the guide rail and is used to fix the photovoltaic module.
[0013] Furthermore, the connecting assembly includes a slider and a pressure block. The slider is slidably disposed in the upper half of the guide rail, and the pressure block is located above the guide rail and is fixedly connected to the slider by bolts.
[0014] The above technical solution allows the pressure block to be flexibly adjusted in position, facilitating the fixing of photovoltaic modules of different sizes and installation locations. During installation, there is no need to precisely determine the position of the pressure block in advance; adjustments can be made on-site according to actual conditions, improving the convenience and efficiency of installation. Furthermore, the bolted connection method ensures a firm and reliable connection, effectively guaranteeing a stable connection between the photovoltaic modules and the guide rail during long-term use, preventing the photovoltaic modules from loosening or falling off, enhancing the stability and safety of the entire photovoltaic system, and also facilitating disassembly and maintenance.
[0015] Furthermore, the pressing block includes an edge pressing block and a middle pressing block, the edge pressing block pressing the first and last ends of the photovoltaic module frame, and the middle pressing block pressing the adjacent photovoltaic module frame.
[0016] Through the above technical solutions, targeted design can fix photovoltaic modules more reasonably and effectively. For the photovoltaic modules at the beginning and end, the edge pressure blocks can provide reliable end constraints to prevent them from shifting under the action of external wind force, vibration and other forces. The middle pressure blocks can tightly connect adjacent photovoltaic modules, so that the entire photovoltaic module array forms a stable whole, which enhances the photovoltaic system's ability to resist the influence of the external environment, improves the system's wind resistance and earthquake resistance, and ensures that the photovoltaic modules can operate stably in various complex environments.
[0017] Furthermore, the edge pressing block includes a corner code, a first contact point horizontally disposed at the top of the corner code, and a second contact point vertically disposed on the bottom edge of the corner code; the bolt is disposed through the horizontal surface of the corner code and threadedly connected to the corresponding slider below; the bottom surface of the first contact point presses against the edge of the photovoltaic module, and the bottom surface of the second contact point presses against the upper surface of the guide rail; the bottom surfaces of both the first and second contacts have a wavy texture structure.
[0018] Through the above technical solution, the corrugated structure increases the friction between the edge pressure block and the photovoltaic module frame and guide rail, enabling the edge pressure block to fix the photovoltaic module more firmly and prevent it from sliding or shifting during use; it can also better distribute pressure, avoid excessive local pressure from damaging the photovoltaic module frame and guide rail, improve the durability and reliability of the connection parts, ensure that the edge pressure block maintains a good fixing effect during long-term use, and ensure the stable operation of the photovoltaic system.
[0019] Furthermore, the intermediate pressure block has an inverted Z-shaped structure. The intermediate pressure block includes a U-shaped connector and a third contact and a fourth contact located on the top of both sides of the connector. The bottom surface of the connector is provided with a bolt that is threadedly connected to the corresponding slider below. The bottom surfaces of the third contact and the fourth contact are pressed against the frame of the adjacent photovoltaic module. The bottom surfaces of the third contact and the fourth contact also have a wavy structure.
[0020] The above technical solution can stably clamp the frames of adjacent photovoltaic modules from both sides, providing uniform and reliable pressure, ensuring a tight connection between adjacent photovoltaic modules, and enhancing the overall integrity of the photovoltaic module array. The corrugated structure further enhances the friction between the medium pressure block and the photovoltaic module frame, effectively preventing the photovoltaic modules from undergoing relative displacement due to vibration, wind, and other factors during operation, thereby improving the stability and reliability of the photovoltaic system, and also helping to extend the service life of the photovoltaic modules and the entire system.
[0021] Furthermore, the upper surface of the slider is provided with a slide rail, which matches the inner top surface protrusion of the upper half of the guide rail.
[0022] The above technical solutions enable the slider to slide more smoothly and stably on the guide rail, facilitating precise adjustment of the slider and pressure block positions to adapt to different installation requirements. The cooperation between the protrusion and the slide rail can limit the movement of the slider to a certain extent, enhance the fixing effect of the slider on the guide rail, and ensure that the slider will not easily shift when subjected to the pressure of the photovoltaic module and the action of the external environment. This ensures that the pressure block can stably fix the photovoltaic module and improve the stability and reliability of the entire photovoltaic system connection structure.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] (1) A stable structural system is formed by the corrugated support and the guide rail. The corrugated support is used to distribute the load to the film-coated metal tile, avoiding local damage to the roof. The system adopts a non-perforated installation method, which avoids the damage to the roof waterproof layer caused by the traditional perforated support, eliminates the risk of water leakage, and greatly reduces the maintenance cost caused by water leakage in the later stage.
[0025] (2) The reasonable design of the slider and pressure block in the connecting component and the effective fixation of the photovoltaic module by the side pressure block and the middle pressure block ensure that the photovoltaic module can be installed stably in various environments, enhance the overall structural strength and stability of the system, effectively resist the influence of external factors such as wind and vibration, and ensure the safe operation of the photovoltaic system.

[0034] Example:
[0035] The following is in conjunction with the appendix Figure 1 -4 provides further detailed description of this application.
[0036] This application discloses a novel photovoltaic system for coated metal tile roofs, comprising:
[0037] Corrugated support 1, wherein multiple corrugated supports 1 are provided and connected to the corrugated surface of the coated metal tile by welding;
[0038] Guide rail 2 is detachably connected to the upper end of the corrugated support 1. Guide rail 2 and the corrugation of the coated metal tile are arranged in a cross shape. Photovoltaic module 3 is provided on the upper surface of guide rail 2. Guide rail 2 is detachably connected to a connecting component, which is used to fix photovoltaic module 3.
[0039] See Figure 2 , Figure 3 and Figure 4 The connecting component includes a slider 4 and a pressure block. The slider 4 is slidably disposed in the upper half of the guide rail 2, and the pressure block is located above the guide rail 2 and is fixedly connected to the slider 4 by bolts. This allows the pressure block to be flexibly adjusted in position, facilitating the fixing of photovoltaic modules 3 of different sizes and installation positions. During installation, there is no need to accurately determine the position of the pressure block in advance; it can be adjusted on-site according to the actual situation, improving the convenience and efficiency of installation. Furthermore, the bolt connection is firm and reliable, effectively ensuring a stable connection between the photovoltaic module 3 and the guide rail 2 during long-term use, preventing the photovoltaic module 3 from loosening or falling off, enhancing the stability and safety of the entire photovoltaic system, and also facilitating disassembly and maintenance.
[0040] See Figure 2 , Figure 3 and Figure 4 The pressure block includes an edge pressure block 5 and a middle pressure block 6. The edge pressure block 5 presses down on the frame of the first and last photovoltaic module 3, and the middle pressure block 6 presses down on the frame of the adjacent photovoltaic module 3. The targeted design can fix the photovoltaic module 3 more reasonably and effectively. For the first and last photovoltaic module 3, the edge pressure block 5 can provide reliable end restraint to prevent it from shifting under the action of external wind force, vibration and other forces. The middle pressure block 6 can tightly connect the adjacent photovoltaic modules 3, so that the entire photovoltaic module 3 array forms a stable whole, which enhances the photovoltaic system's ability to resist the influence of the external environment, improves the system's wind resistance and earthquake resistance, and ensures that the photovoltaic module 3 can operate stably in various complex environments.
[0041] See Figure 2 and Figure 3The edge clamping block 5 includes a corner bracket 7, a first contact point 8 horizontally positioned at the top of the corner bracket 7, and a second contact point 9 vertically positioned at the bottom edge of the corner bracket 7. A bolt is threaded through the horizontal surface of the corner bracket 7 and connected to the corresponding slider 4 below it. The bottom surface of the first contact point 8 presses against the edge of the photovoltaic module 3, and the bottom surface of the second contact point 9 presses against the upper surface of the guide rail 2. Both the bottom surfaces of the first contact point 8 and the second contact point 9 have a corrugated structure. The corrugated structure increases the friction between the edge clamping block 5 and the edge of the photovoltaic module 3 and the guide rail 2, enabling the edge clamping block 5 to more firmly fix the photovoltaic module 3 and prevent it from sliding or shifting during use. It can also better distribute pressure, avoiding excessive local pressure that could damage the edge of the photovoltaic module 3 and the guide rail 2, improving the durability and reliability of the connection parts, ensuring that the edge clamping block 5 maintains a good fixing effect during long-term use, and ensuring the stable operation of the photovoltaic system.
[0042] See Figure 2 and Figure 4 The intermediate pressure block 6 has an inverted U-shaped structure. It includes a U-shaped connector 10 and third contacts 11 and fourth contacts 12 located on the top of both sides of the connector 10. A bolt is threaded through the bottom surface of the connector 10 and connected to the corresponding slider 4 below. The bottom surfaces of the third contacts 11 and fourth contacts 12 press against the frame of the adjacent photovoltaic module 3. The bottom surfaces of the third contacts 11 and fourth contacts 12 also have a wavy structure. This allows for stable clamping of the frame of the adjacent photovoltaic module 3 from both sides, providing uniform and reliable pressure, ensuring a tight connection between the adjacent photovoltaic modules 3, and enhancing the overall integrity of the photovoltaic module 3 array. The wavy structure further increases the friction between the intermediate pressure block 6 and the frame of the photovoltaic module 3, effectively preventing relative displacement of the photovoltaic module 3 due to vibration, wind, and other factors during operation, thus improving the stability and reliability of the photovoltaic system and helping to extend the service life of the photovoltaic module 3 and the entire system.
[0043] See Figure 2 and Figure 3 The upper surface of the slider 4 is provided with a slide rail 13, which matches the inner top surface protrusion of the upper half of the guide rail 2. This makes the slider 4 slide more smoothly and stably on the guide rail 2, and facilitates precise adjustment of the position of the slider 4 and the pressure block to adapt to different installation requirements. The cooperation between the protrusion and the slide rail 13 can limit the movement of the slider 4 to a certain extent, enhance the fixing effect of the slider 4 on the guide rail 2, and ensure that the slider 4 will not easily shift when subjected to the pressure of the photovoltaic module 3 and the action of the external environment. This ensures that the pressure block can stably fix the photovoltaic module 3 and improve the stability and reliability of the entire photovoltaic system connection structure.
[0044] The implementation principle of a novel photovoltaic system for a coated metal tile roof in this application embodiment is as follows: First, multiple corrugated supports 1 are uniformly fixed to the corrugated surface of the coated metal tile by welding. Welding is used to tightly connect the corrugated supports 1 with the roof polymer waterproof membrane to form a solid foundation fixing point.
[0045] Next, the guide rail 2 is detachably connected to the upper end of the corrugated support 1, so that the guide rail 2 and the corrugation direction of the coated metal tile intersect in a cross shape, forming the support frame of the photovoltaic module 3. When installing the photovoltaic module 3, the slider 4 is slidably set in the upper half of the guide rail 2. The slider 4 is adjusted according to the placement position of the photovoltaic module 3. Then, the edge pressure block 5 and the middle pressure block 6 are placed at the frame of the photovoltaic module 3 respectively. The pressure block and the slider 4 are fixedly connected by bolts, so that the edge pressure block 5 presses the frame of the first and last photovoltaic module 3, and the middle pressure block 6 presses the adjacent frame of the photovoltaic module 3, thereby stably fixing the photovoltaic module 3 on the guide rail 2.
[0046] Throughout the process, the wave crest support 1 transfers the load generated by the photovoltaic module 3 to the coated metal tile. The strong bending resistance of the wave crest of the coated metal tile disperses the load, ensuring the safety of the roof structure. The sliding fit between the slider 4 and the guide rail 2 facilitates the adjustment of the pressure block position. The tight connection between the pressure block and the photovoltaic module 3 and the guide rail 2 ensures that the photovoltaic module 3 is firmly fixed, realizing the stable installation and operation of the photovoltaic system on the coated metal tile roof.
[0047] Multiple photovoltaic modules 3 form a section (e.g., eight photovoltaic modules 3). Adjacent sections are isolated by cable trays and maintenance channels. The cable trays and maintenance channels can also be fixed on the guide rails 2.
[0048] 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.
