Description

Technical Field

[0001] This invention relates to the field of photovoltaic equipment technology, and more specifically, to a lock-edge tile structure and installation method for building-integrated photovoltaics. Background Technology

[0002] With the increasing global demand for clean energy, and in order to achieve the goals of energy conservation, emission reduction, and sustainable development, the government has introduced a number of policies to encourage the application of Building Integrated Photovoltaics (BIPV) and promote the development of energy-efficient and green buildings. However, installing photovoltaic systems on plastic roofing sheets, which are frequently used in corrosive industries, faces many challenges, such as connection strength, screw leakage, ease of installation, and coordination with the overall building structure. For example, traditional photovoltaic panel installation methods usually require the addition of clamps and guide rails, which makes the installation process complex, consuming a lot of time and manpower, and significantly increasing installation costs. Moreover, traditional installation methods often use exposed nails to fix the roof through the tile surface, which greatly increases the risk of roof leakage and corrosion, seriously affecting the waterproof performance and service life of the roof. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a lock-edge tile structure and installation method for building photovoltaic integration.

[0009] Furthermore, the shape of the head structure is the same as that of the mother side wave. When the head structure is fitted into the inner wall of the bottom groove of the mother side wave, the groove on the upper surface of the head structure fits onto the protrusion on the inner wall of the bottom groove of the mother side wave.

[0010] Furthermore, the lock-edge tile structure for building-integrated photovoltaics further includes: a filling fastener that can be snapped onto the outer wall of the head structure, the structure of the filling fastener being the same as the structure of the male side wave; when the head structure is assembled into the male side wave or the bottom groove of the assembled tile wave, the outer wall of the filling fastener is in contact with the inner wall of the bottom groove of the male side wave or the assembled tile wave to fill the filling area between the bottom groove of the male side wave or the assembled tile wave and the head structure.

[0011] Furthermore, the support fastener also includes: support transverse sides connected to both sides of the bottom groove of the head structure, so as to support and cooperate with the lower surface of the lock edge tile body planar structure by means of the two support transverse sides; the two support transverse sides are connected to two oppositely arranged L-shaped assembly beams, and the crossbeams of the L-shaped assembly beams are installed on the purlins by screws.

[0012] Furthermore, the lock-edge tile structure for building photovoltaic integration further includes: a windproof clamp; the bottom of the windproof clamp is provided with a locking groove for locking and engaging with the upper surface of the male side wave, female side wave, or assembly tile wave, and a plurality of clamping grooves are evenly arranged on the inner wall of the locking groove along the length direction of the windproof clamp; the pressing edge of the bottom of the windproof clamp abuts against the upper surface of the lock-edge tile body planar structure.

[0013] Furthermore, the aforementioned lock-edge tile structure for building-integrated photovoltaics (BIPV) further includes: a photovoltaic connection clamp; the photovoltaic connection clamp includes: a clamping part and a right-angle pressure block; two clamping slots of the two clamping parts cooperate to form an assembly slot for locking connection on the male side wave, female side wave, or assembly tile wave; the vertical connecting plate above the two clamping parts is connected to the vertical support block below the two right-angle pressure blocks by clamping screws and clamping nuts, and the horizontal clamping plate above the two right-angle pressure blocks is connected to the photovoltaic overlapping surface above the two clamping parts by pressure block screws and pressure block nuts; a clamping area for clamping photovoltaic panels is formed between adjacent horizontal clamping plates and the photovoltaic overlapping surface of the clamping parts.

[0015] Install multiple support fasteners on the purlins to connect the male side wave, the female side wave, and the assembly wave;

[0016] According to actual needs, install the required number of lock edge tile bodies on the support fasteners. The male side wave, female side wave and assembly tile wave of the lock edge tile body are all connected to a support fastener. Between two adjacent lock edge tile bodies, the female side wave of one lock edge tile body is concentrically overlapped and attached to the bottom groove inner wall of the male side wave of the other lock edge tile body.

[0017] Photovoltaic connection clamps are installed on the male and female side waves of the lock-edge tile body, and windproof clamps are installed on the assembled tile wave. The windproof clamps are used to securely connect the assembled tile wave to the support fastener.

[0018] The photovoltaic panels can be installed in the clamping area formed between two adjacent photovoltaic connection clamps.

[0019] As can be seen from the above solution, the beneficial effects of the present invention are as follows:

[0020] In the lock-edge tile structure and installation method for building-integrated photovoltaics (BIPV) of the present invention, the lock-edge tile body adopts a special tile shape design. The lock-edge tile body, together with the support fastener, can achieve nail-free installation of the tile surface, avoiding the risk of roof leakage and corrosion caused by exposed nails passing through the tile surface. The lock-edge tile body, together with the photovoltaic connection clamp, can achieve stable installation of photovoltaic panels.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0043] Example 1

[0044] Please see Figures 1-13 This invention provides a lock-edge tile structure for building-integrated photovoltaics (BIPV), comprising: a lock-edge tile body 100; a male edge wave 101 and a female edge wave 102 respectively provided at both ends of the lock-edge tile body 100; the upper surface of the female edge wave 102 is provided with a groove arranged along its length direction; when the female edge wave 102 of one lock-edge tile body 100 concentrically overlaps and adheres to the inner wall of the bottom groove of the male edge wave 101 of another lock-edge tile body 100, a pressure relief groove 103 for preventing siphon leakage is formed between the groove of the female edge wave 102 and the inner wall of the bottom groove of the male edge wave 101. The lock-edge tile body 100 is also provided with one or more mounting wave 104, the structure of which is the same as that of the male edge wave 101, and the mounting wave 104 is located between the male edge wave 101 and the female edge wave 102. The male side wave 101, the female side wave 102, and the assembled tile wave 104 are all large-head and narrow-waisted wave structures, each including: a cylindrical wave structure with a bottom groove at the bottom and two inclined overlapping structures connected to both sides of the bottom groove. The distance between the two inclined overlapping structures near the end of the cylindrical wave structure is less than the distance between the two inclined overlapping structures away from the cylindrical wave structure.

[0045] The working principle and technical effects of the above technical solution are as follows:

[0046] The lock-edge tile body 100 adopts a special tile shape design. Each lock-edge tile body 100 has a male side wave 101 and a female side wave 102 at both ends, suitable for continuous full-lay, realizing BIPV (Building Integrated Photovoltaics). When connecting two adjacent lock-edge tile bodies 100, after fixing one lock-edge tile body 100, the female side wave 102 of the other lock-edge tile body 100 concentrically overlaps and adheres to the bottom groove inner wall of the male side wave 101 of the other lock-edge tile body 100. Because the male side wave 101, female side wave 102, and assembly tile wave 104 are all large-head, narrow-waisted waveform structures, the two... The connection of the lock-edge tile body 100 is relatively stable, and a pressure relief groove 103 is formed between the groove of the female side wave 102 and the inner wall of the bottom groove of the male side wave 101 to prevent siphon leakage, which has the effect of pressure relief and preventing siphon. The male side wave 101 and the female side wave 102 are concentric and tightly fitted, with a large end and a narrow waist, which is suitable for lock-edge installation and avoids the risk of leakage caused by screws directly passing through the tile surface. It can achieve continuous full-lay and guide rail-free installation, improve installation efficiency and save costs. The lock-edge tile body 100 in this invention is made of corrosion-resistant plastic material, which reduces the risk of corrosion and rust compared with traditional metal tiles.

[0047] The lock-edge tile structure for building photovoltaic integration further includes: a support fastener 200 for supporting and fixing the lock-edge tile body 100, the support fastener 200 being connected to the purlin 300, and the support fastener 200 being provided with a head structure 201 for fitting into the bottom groove of the male side wave 101, the female side wave 102, or the mounting tile wave 104.

[0048] The working principle and technical effect of the above technical solution are as follows: The support fastener 200 is used to fix and support the edge-locking tile body 100, so that the edge-locking tile body 100 does not need to be connected to the purlin 300 by screws. When assembling photovoltaic modules, multiple support fasteners 200 are first installed on the purlin 300 according to the wave pitch of the edge-locking tile body 100, that is: the wave pitch of two adjacent waveforms in the male side wave 101, female side wave 102 and assembly tile wave 104. During installation, the male side wave 101, female side wave 102 and assembly tile wave 104 of the first edge-locking tile body 100 are first aligned. All the corrugated tiles 104 are connected to the support fasteners 200, thereby improving the stability of the installation. Then, the second locking tile body 100 is installed. The male side corrugation 101 of the second locking tile body 100 is connected to the female side corrugation 102 of the first locking tile body 100. The female side corrugation 102 of the second locking tile body 100 and the corrugated tiles 104 are all connected to other support fasteners 200. By continuously laying them, the overall roof can be laid. The support strength is high, and there is no need to avoid the risk of leakage caused by screws directly passing through the tile surface of the locking tile body 100.

[0049] The head structure 201 has the same shape as the mother side wave 102. When the head structure 201 is fitted into the inner wall of the bottom groove of the mother side wave 102, the groove on the upper surface of the head structure 201 fits into the protrusion on the inner wall of the bottom groove of the mother side wave 102, resulting in a tight connection and good stability.

[0050] The lock-edge tile structure for building-integrated photovoltaics further includes: a filling fastener 400 that can be snapped onto the outer wall of the head structure 201, the structure of the filling fastener 400 being the same as the structure of the male side wave 101; when the head structure 201 is assembled into the bottom groove of the male side wave 101 or the assembly tile wave 104, the outer wall of the filling fastener 400 is in contact with the inner wall of the bottom groove of the male side wave 101 or the assembly tile wave 104 to fill the filling area between the bottom groove of the male side wave 101 or the assembly tile wave 104 and the head structure 201.

[0051] The working principle and technical effect of the above technical solution are as follows: Since the size of the support fastener 200 is a fixed size, the shape of the head structure 201 of the support fastener 200 is the same as the structure of the female side wave 102, and its size is smaller than the size of the female side wave 102 of the locking tile body 100. This results in the male side wave 101 or the mounting wave 104 not being able to fit tightly with the head structure 201 of the support fastener 200 when they are used together, and there is a gap between them, which affects the stability of the support connection. Therefore, the present invention also includes a filling fastener 400 that can be snapped onto the outer wall of the head structure 201. When the head structure 201 is assembled into the bottom groove of the male side wave 101 or the mounting wave 104, the outer wall of the filling fastener 400 fits against the inner wall of the bottom groove of the male side wave 101 or the mounting wave 104 to fill the filling area between the bottom groove of the male side wave 101 or the mounting wave 104 and the head structure 201, thereby improving the stability of the connection between the supporting fastener 200 and the locking tile body 100, and making installation and disassembly more convenient and reusable.

[0052] The support fastener 200 further includes: a support transverse edge 202 connected to both sides of the bottom groove of the head structure 201, so as to support and cooperate with the lower surface of the planar structure of the lock edge tile body 100 through the two support transverse edges 202; the two support transverse edges 202 are connected to two L-shaped assembly beams 203 arranged opposite to each other, and the crossbeams of the L-shaped assembly beams 203 are installed on the purlin 300 by screws. In this invention, the crossbeam of the L-shaped assembly beam 203 is installed on the purlin 300 with screws, providing a stable foundation for the support fastener 200. The purlin is an important component in the building structure used to support the roof. The reliable connection between the L-shaped assembly beam and the purlin ensures that the entire support system will not easily shift or loosen during long-term use, providing stable support for the lock-edge tile body 100 and photovoltaic panels, etc. The two support crossbeams 202 support and cooperate on the lower surface of the plane structure of the lock-edge tile body 100, increasing the contact area between the support fastener 200 and the lock-edge tile body 100. According to the principle of physics, under a certain pressure, the larger the contact area, the smaller the pressure per unit area. By dispersing the pressure, the local stress concentration is reduced, avoiding damage to the lock-edge tile body 100 due to excessive local stress, thereby improving the stability of the entire support structure.

[0053] The lock-edge tile structure for building photovoltaic integration further includes: a windproof clamp 500; the bottom of the windproof clamp 500 is provided with a locking groove for locking and engaging with the upper surface of the male side wave 101, the female side wave 102 or the mounting tile wave 104, and a plurality of clamping grooves are evenly arranged on the inner wall of the locking groove along the length direction of the windproof clamp 500; the pressing edge of the bottom of the windproof clamp 500 abuts against the upper surface of the planar structure of the lock-edge tile body 100.

[0054] The working principle and technical effects of the above technical solution are as follows:

[0055] The windproof clamp 500 has a locking groove at its bottom, which can lock onto the upper surface of the male side wave 101, female side wave 102, or mounting tile wave 104. This tightly connects the head structure 201 of the support fastener 200 to the locking tile body 100, effectively resisting wind forces and preventing displacement or lifting between the locking tile body 100 and the head structure 201 in strong winds, thus enhancing the windproof stability of the entire building photovoltaic integrated system. Multiple clamping grooves are evenly arranged on the inner wall of the locking groove along the length of the windproof clamp 500, increasing friction with the side wave surface. The friction further enhances the tightness of the connection between the lock-edge tile body 100 and the head structure 201, making it less prone to slippage when subjected to wind impact, thus better fulfilling its windproof function. The pressure edge at the bottom of the windproof clamp 500 abuts against the upper surface of the planar structure of the lock-edge tile body 100. The pressure edge provides additional downward pressure to the lock-edge tile body 100, making the lock-edge tile body 100 and the head structure 201 more firmly attached to the supporting horizontal edge 202, reducing swaying and deformation caused by wind or other external forces, and enhancing the overall stability of the lock-edge tile body 100. The locking groove of the windproof clamp 500 can be adapted to the male side wave 101, the female side wave 102, or the mounting wave 104, and has strong versatility. During installation, it is not necessary to design different windproof clamps for different types of side waves, simplifying the installation process, improving installation efficiency, and reducing installation costs. At the same time, it also facilitates subsequent maintenance and replacement work; after the windproof clamp 500 is set on the male side wave 101, the female side wave 102 or the assembly wave 104, it is clamped with bite pliers to improve the fixing effect. The windproof clamp 500 is made of aluminum alloy material or plastic-coated aluminum-magnesium-zinc material.

[0056] The aforementioned lock-edge tile structure for building-integrated photovoltaics (BIPV) further includes: a photovoltaic connection clamp 600; the photovoltaic connection clamp 600 includes: a clamping part 601 and a right-angle pressure block 602; the two clamping slots of the two clamping parts 601 cooperate to form an assembly slot for locking connection on the male side wave 101, the female side wave 102, or the assembly tile wave 104; the vertical connecting plate above the two clamping parts 601 is connected to the vertical support block below the two right-angle pressure blocks 602 by clamping screws 603 and clamping nuts, and the horizontal clamping plate above the two right-angle pressure blocks 602 is connected to the photovoltaic overlapping surface above the two clamping parts 601 by pressure block screws 604 and pressure block nuts; a clamping area for clamping photovoltaic panels 900 is formed between adjacent horizontal clamping plates and the photovoltaic overlapping surface of the clamping parts 601.

[0057] The working principle and technical effects of the above technical solution are as follows:

[0058] The clamping slots on the two clamping parts 601 of the photovoltaic connection clamp 600 cooperate to form an assembly slot. The assembly slot can be locked with the male edge wave 101, female edge wave 102, or assembly tile wave 104 in the edge-locking tile body 100, fixing the photovoltaic connection clamp 600 onto the edge-locking tile body 100 and providing a stable foundation for subsequent photovoltaic panel installation. The vertical connecting plate above the two clamping parts 601 and the vertical support block below the two right-angle pressure blocks 602 are connected by clamp screws 603 and clamp nuts, fixing the clamping parts 601 and right-angle pressure blocks 602 in the vertical direction and ensuring the relative position stability between them. The horizontal clamping plate above the two right-angle pressure blocks 602 and the photovoltaic overlapping surface above the two clamping parts 601 are connected by pressure block screws 603 and 604. The connection between the right-angle pressure block 602 and the clamping part 601 is further strengthened by the connection with the pressure block 604 and the clamping part 601, which also creates conditions for the installation and fixing of the photovoltaic panel. A clamping area is formed between the adjacent horizontal clamping plates and the photovoltaic overlapping surface of the clamping part 601. When installing the photovoltaic panel 900, it is placed in the clamping area, and then the photovoltaic panel 900 is locked and fixed by adjusting the pressure block screw 604 and the pressure block nut, so that it is firmly installed on the locking tile. The entire installation process of the photovoltaic connection clamp 600 is mainly connected by screws and nuts. This connection method is simple to operate and does not require complicated tools and processes. During installation, you only need to assemble the various parts according to the above connection method. During disassembly, the clamp can be easily separated from the locking tile and the photovoltaic panel by loosening the screws and nuts. This greatly improves the efficiency of installation and maintenance, and reduces labor and time costs. The assembly slot of the photovoltaic connection clamp 600 can be connected to the male side wave 101, the female side wave 102 or the assembly tile wave 104, which has good versatility and adaptability. The photovoltaic connection clamp can be used to install photovoltaic panels in different locking tile structures, thus improving the applicability of the product. When installing the photovoltaic panel 900, the width of the edge-locking tile body 100 is a multiple of the installation width of the photovoltaic panel. Combined with the windproof clamp 500 and the photovoltaic connection clamp 600, continuous full-laying is achieved, eliminating the need for traditional guide rail installation. This effectively reduces costs and improves installation efficiency, and facilitates recycling and reuse. The photovoltaic connection clamp 600 also raises the installation position of the photovoltaic panel 900, preventing direct contact between the photovoltaic panel 900 and the tile surface. This creates a heat dissipation space between them, preventing temperature accumulation and excessively high local temperatures that could affect the photovoltaic lifespan. Furthermore, raising the installation position creates a natural channel between the bottoms of each photovoltaic panel 900, allowing for free horizontal and vertical wiring connections as needed. This effectively avoids light spot effects caused by improper wiring connections, reducing the impact on its service life.

[0059] Example 2

[0060] Please see Figures 1-17To improve the connection and support stability between the photovoltaic panel 900 and the locking tile body 100, the locking tile structure for building-integrated photovoltaics further includes: a socket base 700, the socket base 700 having a socket groove at its bottom that fits onto the outer wall of a windproof clamp 500; multiple locking screws screwed onto the left and right sides of the socket base 700 engaging with grooves on the left and right sides of the windproof clamp 500; an insulating and heat-insulating elastic pad for supporting the photovoltaic panel is provided on the top of the socket base 700; two opposing shielding and anti-detachment structures 800 rotate in the side grooves on the left and right sides of the socket base 700; the ends of the four shielding and anti-detachment structures 800 away from the socket base 700 are all engaged with the photovoltaic panel 900 and engaging with the outer surfaces of the clamping portions 601 of two adjacent photovoltaic connection clamps 600. A drainage channel penetrating both ends of the socket base 700 is provided in the middle of the socket base 700. When the photovoltaic panel is installed at an angle, it serves to drain rainwater.

[0061] The working principle and technical effect of the above solution are as follows: the socket groove at the bottom of the socket 700 fits onto the outer wall of the windproof clamp 500; multiple locking screws screwed on the left and right sides of the socket 700 abut against the grooves on the left and right sides of the windproof clamp 500, thereby effectively locking the windproof clamp 500 onto the locking tile body 100 and the support fastener 200, preventing loosening between them; the top of the socket 700 is provided with an insulating and heat-insulating elastic pad for supporting the photovoltaic panel, improving its support for the photovoltaic panel 900. To ensure stability and avoid the problem of poor stability caused by insufficient support in the middle of the photovoltaic panel 900 between the two photovoltaic connection clamps 600 due to excessive spacing between them, two opposing shielding and anti-detachment structures 800 are rotated in the side grooves on both sides of the socket 700. The ends of the four shielding and anti-detachment structures 800 away from the socket 700 are all engaged with the photovoltaic panel 900, further limiting the upper surface of the photovoltaic panel 900 and reducing the probability of it falling off. The end of the connector 700 that is furthest from the socket abuts against the outer surface of the clamping part 601 of the two adjacent photovoltaic connection clamps 600. In the actual application scenario of building photovoltaic integration, if debris enters the space between the photovoltaic panel and the locking tile body, it will have many adverse effects on the performance of the entire system. Dust, leaves, pebbles and other debris are common in the natural environment. Under the action of wind, hard objects such as pebbles may roll and collide in this space, scratching the protective layer on the lower surface of the photovoltaic panel, damaging the structural integrity of the photovoltaic panel, and causing its performance to decline or even be damaged. After the shading and anti-detachment structure 800 seals this space, it can effectively resist the intrusion of various types of debris. In addition, in some severe weather, such as in windy weather, if the space between the photovoltaic panel and the locking tile body is not sealed, the wind will enter and generate complex airflow and pressure changes, causing huge upward lifting force on the photovoltaic panel, seriously threatening the installation stability of the photovoltaic panel. After the shading and anti-detachment structure 800 seals this space, it can effectively balance the wind pressure on the upper and lower surfaces of the photovoltaic panel. When strong winds strike, if the space is open, the airflow will create upward pressure below the photovoltaic panels. The presence of the protective anti-detachment structure prevents strong winds from directly entering the space, reducing the wind pressure below and keeping the pressure difference between the upper and lower surfaces of the photovoltaic panels within a safe range. This prevents the photovoltaic panels from loosening, shifting, or even being overturned due to excessive wind pressure differences, ensuring that the photovoltaic panels remain firmly installed on the roofing tile body even in severe weather conditions. Strong winds not only exert an upward lifting force on the photovoltaic panels but can also cause vibration and swaying of the entire building-integrated photovoltaic (BIPV) structure. The enclosed space provided by the protective anti-detachment structure enhances the tightness of the connection between the photovoltaic panels and the roofing tile body, making them form a more stable whole. Under the influence of strong winds, this stable overall structure can better resist the impact of wind, reducing component damage and loosening of connections caused by structural swaying.

[0062] The protective and anti-detachment structure 800 includes: a fixed protective plate 801, one end of which is rotatably connected to the side groove of the sleeve seat 700; the other end of the fixed protective plate 801 is provided with a cross-shaped sliding groove, in which a movable protective plate 802 is slidably connected; the upper surface of the fixed protective plate 801 and the upper surface of the movable protective plate 802 are coplanar, and the lower surface of the fixed protective plate 801 and the lower surface of the movable protective plate 802 are coplanar; a cylindrical sliding groove is provided in the cross-shaped sliding groove, and a limiting compression spring 803 fixed in the cylindrical sliding groove is fixedly connected to a cylindrical sliding rod 804 fixed to one end of the movable protective plate 802; the cylindrical sliding rod 804 can slide in the cylindrical sliding groove; a longitudinal support column 805 is rotatably connected to the end of the movable protective plate 802 away from the fixed protective plate 801. A horizontal sliding column 806 is slidably connected to the middle of the support column 805. The front and rear ends of the horizontal sliding column 806 are connected to the lower right-angle head and the limiting block 807, respectively. A tension spring 808 is sleeved on the column body of the horizontal sliding column 806 located between the limiting block 807 and the longitudinal support column 805. A longitudinal guide column 809 is fixed at the end of the lower right-angle head away from the horizontal sliding column 806. The longitudinal guide column 809 is slidably fitted inside the longitudinal sleeve 810. The limiting protrusion on the side wall of the longitudinal guide column 809 is slidably installed in the limiting groove on the side wall of the longitudinal sleeve 810. A tension spring 811 is fixed between the top surface inside the longitudinal sleeve 810 and the longitudinal guide column 809. The top of the longitudinal sleeve 810 is connected to the anti-detachment pressure rod 812 for pressing on the upper surface of the photovoltaic panel 900 through the upper right-angle head.

[0063] The working principle and technical effect of the above scheme are as follows: One end of the fixed shielding plate 801 is rotatably connected to the side groove of the socket 700, and can rotate around the connection point to adapt to different installation and use angles. The movable shielding plate 802 is slidably connected to the fixed shielding plate 801 through a cross-shaped sliding groove. At the same time, the cylindrical sliding groove, the limiting spring 803, and the cylindrical sliding rod 804 in the cross-shaped sliding groove constitute a telescopic adjustment mechanism. When the outer end of the movable shielding plate 802 is controlled to abut against the outer side of the clamping part 601 of the photovoltaic connection clamp 600, if the length of the shielding plate structure formed by the movable shielding plate 802 and the fixed shielding plate 801 in the normal state is relatively long, the movable shielding plate 802 is controlled to abut against the fixed shielding plate 801. The plate 801 slides within the cross groove and is compressed by the cylindrical slide rod 804 against the limiting spring 803. The limiting spring 803 ensures that the movable shielding plate 802 effectively abuts against the outer surface of the clamping part 601 of the photovoltaic connection clamp 600, maintaining it in a relatively stable position. The end of the movable shielding plate 802 away from the fixed shielding plate 801 is rotatably connected to the longitudinal support column 805. The middle of the longitudinal support column 805 is slidably connected to the transverse sliding column 806. The tensioning spring 808 sleeved on the transverse sliding column 806 is located between the limiting block 807 and the longitudinal support column 805. When it is necessary to control the anti-detachment pressure rod 812 to be locked on the upper surface of the photovoltaic panel 900, the longitudinal sleeve 810 is pulled outward. The sleeve 810 drives the transverse sliding column 806 to slide outward via the longitudinal guide post 809. The transverse sliding column 806 drives the limiting block 807 to compress the tension spring 808, allowing the anti-disengagement rod 812 to be locked onto the upper surface of the photovoltaic panel 900. The longitudinal guide post 809 slides inside the longitudinal sleeve 810, and the limiting protrusion on the side wall of the longitudinal guide post 809 slides within the limiting groove on the side wall of the longitudinal sleeve 810. This restricts the sliding direction of the longitudinal guide post 809, allowing it to slide only in a straight line within the longitudinal sleeve 810. The tension spring 811, fixed between the top surface inside the longitudinal sleeve 810 and the longitudinal guide post 809, generates tension when the longitudinal guide post 809 slides, thus controlling the tension spring. The combined action of the compression spring 808 further enhances the stability and elasticity of the structure. When the anti-detachment pressure rod 812 is pressed against the upper surface of the photovoltaic panel 900 under the elastic force of the tension spring 811, the tension spring 811 provides elastic buffering between the anti-detachment pressure rod 812 and the upper surface of the photovoltaic panel 900. This ensures that while the anti-detachment pressure rod 812 limits the position of the photovoltaic panel 900, it will not suffer hard damage due to vibration or displacement caused by external forces. The anti-detachment pressure rod 812 can be adjusted in position and pressure according to actual conditions to ensure appropriate pressure is applied to the photovoltaic panel 900, achieving effective limiting and fixation of the photovoltaic panel. The telescopic design of the fixed shielding plate 801 and the movable shielding plate 802 allows the shielding length of the anti-detachment structure 800 to be adjusted according to actual needs. Under different installation environments and photovoltaic panel layouts, the shading range can be flexibly adjusted to better seal the space between the photovoltaic panel and the lock-edge tile body, preventing debris from entering and strong winds from invading, thus improving the versatility and adaptability of the structure.

[0064] Example 3

[0065] Please see Figures 1-13 The present invention also provides an installation method for installing the aforementioned lock-edge tile structure for building-integrated photovoltaics, comprising:

[0066] Multiple support fasteners 200 are installed on the purlin 300 for connecting the male side wave 101, the female side wave 102 and the mounting wave 104;

[0067] According to actual needs, the required number of lock edge tile bodies 100 are installed on the support fastener 200. The male side wave 101, female side wave 102 and assembly wave 104 of the lock edge tile body 100 are all connected to a support fastener 200. Between two adjacent lock edge tile bodies 100, the female side wave 102 of one lock edge tile body 100 is concentrically overlapped and attached to the bottom groove inner wall of the male side wave 101 of the other lock edge tile body 100.

[0068] Photovoltaic connection clamps 600 are installed on the male side wave 101 and female side wave 102 of the lock edge tile body 100, and windproof clamps 500 are installed on the assembly tile wave 104. The assembly tile wave 104 is fastened to the support fastener 200 through the windproof clamps 500.

[0069] The photovoltaic panels can be installed in the clamping area formed between two adjacent photovoltaic connection clamps 600.

[0070] The above solution has the following technical effects:

[0071] This installation method clearly divides the entire installation process into multiple steps, from the installation of support fasteners to the installation of the edge-locking tile body, then to the installation of photovoltaic connection clamps and windproof clamps, and finally the installation of the photovoltaic panels. Each step has clear operating instructions, allowing construction personnel to install in an orderly manner, reducing installation difficulty and minimizing errors and problems caused by improper operation. The descriptions of each step are concise and clear, enabling even construction personnel without extensive installation experience to successfully complete the installation work, improving the operability and efficiency of the installation work. First, multiple support fasteners are installed on the purlins, providing a stable support foundation for the subsequent installation of the edge-locking tile body. The support fasteners connect with the male and female side corrugations and the assembly tile corrugations, which can evenly distribute the weight of the edge-locking tile body and the photovoltaic panel, ensuring the stability of the entire structure. Adjacent edge-locking tile bodies... The female side wave is concentrically overlapped and attached to the inner wall of the bottom groove of the male side wave. This not only increases the tightness of the connection but also effectively prevents rainwater penetration, improving the waterproof performance of the roof and the stability of the overall structure. Installing windproof clamps ensures a secure connection between the lock-edge tile body and the supporting fasteners, effectively resisting the effects of wind and other external forces, reducing structural deformation and damage caused by external forces. The number of lock-edge tile bodies required can be determined according to actual needs. This flexibility allows the installation method to adapt to the needs of buildings of different sizes and shapes, whether small buildings or large commercial buildings, by adjusting the number of lock-edge tile bodies to meet installation requirements. By installing photovoltaic connection clamps on the male and female side waves and windproof clamps on the assembled tile wave, the installation of photovoltaic panels can be well adapted, realizing the function of building-integrated photovoltaics and improving energy utilization efficiency.
