[0033] In the first specific embodiment, the quick-release clamp 1 provided by the present invention includes a base plate 10 and a pressure plate 9 and a side plate 12 arranged on both sides of the base plate 10. The base plate 10 is fixedly connected to the color steel tile, and the pressure plate 9 and the side plate 12 are evenly spaced in both the horizontal and vertical directions. The pressure plate 9 and the side plate 12 are provided with limit cards that are buckled with the photovoltaic component 2, so that the photovoltaic component 2 can be clamped and fixed to the pressure plate 9 and the side plate 12, thereby realizing the clamping and fixing of the photovoltaic component 2 on both sides of the quick-release clamp 1.

[0034] In this embodiment, the quick-release clamp 1 is provided with a reinforcing rib 11. The quick-release clamp 1 is integrally formed. Unlike the prior art in which the photovoltaic component 2 needs to be fixed with screws or self-tapping screws, there is a risk of water leakage in the pores, and the installation and construction are complicated, the photovoltaic component 2 and the quick-release clamp 1 are clamped and fixed to avoid problems such as rust in the pores due to the infiltration of rainwater. This effectively solves the problems of high installation and construction costs, water leakage, and corrosion risks in the existing photovoltaic building integrated system of industrial plants, reduces the later operation and maintenance costs, and effectively improves the safety of the product.

[0035] In this embodiment, the side plate 12 is formed by bending a part of the quick-install clamp 1 downward, the bottom plate 10 is formed by bending a part of the quick-install clamp 1 outward, and the pressure plate 9 is formed by bending a part of the quick-install clamp 1 outward. In addition, the photovoltaic module 2 includes a module glass 19 and a module frame 17 provided at the edge of the module glass 19, the module frame 17 includes a frame body and a first card slot 16 and a second card slot 18 provided in the frame body, the module frame 17 is integrally formed, and the quick-install clamp 1 is an integrally formed elastic component, which is fixed between the pressure plate 9 and the side plate 12 through the module frame 17, thereby fixing the photovoltaic module 2 and the quick-install clamp 1.

[0036] Furthermore, the pressure plate 9 is provided with a first limit card 8, the side plate 12 is provided with a third limit card 14, and the component frame 17 is provided with a first card slot 16 and a second card slot 18. When the photovoltaic component 2 is pushed into the first limit card 8 and the third limit card 14, the first limit card 8 is engaged with the first card slot 16 and the third limit card 14 is engaged with the second card slot 18.

[0037] In addition, a second limit card 15 is provided inside the quick-release clamp 1, and a fourth limit card 13 is provided on the side plate 12. The second limit card 15 is engaged with the vertical edge formed by the locking edge of the color steel tile, and the fourth limit card 13 is engaged with the upper surface of the step of the color steel tile.

[0038] In this embodiment, when the component is installed, the first limit card 8 is engaged with the first card slot 16 of the component frame 17, and the second limit card 15 is engaged with the vertical edge formed by the locking edge of the color steel tile to ensure that the quick-release clamp 1 and the photovoltaic component 2 will not loosen from the color steel tile under negative wind pressure. The third limit card 14 is engaged with the second card slot 18 of the component frame 17 to fix the component. The fourth limit card 13 is engaged with the upper surface of the step of the color steel tile to prevent the photovoltaic component 2 from sliding down. The bottom plate 10 is pressed on the upper surface of the component frame 17. The clamping method of the limit card avoids the operation of drilling holes in the color steel tile, greatly reducing the risk of water leakage.

[0039] Among them, the fourth limit card 13 is formed by a part of the quick-loading clamp 1 being bent downward from the bottom plate 10, the third limit card 14 is formed by a part of the quick-loading clamp 1 being bent upward from the bottom plate 10, the third limit card 14 is perpendicular to the fourth limit card 13, the first limit card 8 is formed by a part of the quick-loading clamp 1 being bent downward from the pressure plate 9, and the second limit card 15 is formed by a part of the quick-loading clamp 1 being bent inward from the side plate 12. The above-mentioned limit cards are elastically deformed to achieve the installation and fixation of the quick-loading clamp 1 on the color steel tile and the engagement and fixation with the photovoltaic component 2.

[0040] In addition, the first limit card 8 is set at an angle to the pressure plate 9, the second limit card 15 is set at an angle to the side plate 12, the third limit card 14 and the fourth limit card 13 are set at an angle to the bottom plate 10, and the third limit card 14 and the fourth limit card 13 are set vertically; the limit card of the quick-release clamp 1 can pierce the oxide film on the surface of the component frame 17 to achieve contact connection between the limit card and the component frame 17, thereby ensuring the electrical safety of the photovoltaic power generation system.

[0041] During installation, the pressure plate 9 is pressed against the upper surface of the component frame 17, and at the same time, the first limit card 8 set at an angle to the pressure plate 9 is stuck in the first card groove 16 on the upper surface of the component frame 17, ensuring the reliability of the fixation of the upper surface of the photovoltaic component 2, and the third limit card 14 set at an angle to the bottom plate 10 is stuck in the second card groove 18 below the component frame 17, further ensuring the reliability of the fixation of the photovoltaic component 2 and the quick-release clamp 1, and preventing the photovoltaic component 2 from loosening.

[0042] Furthermore, the quick-release clamps 1 can be regularly distributed on the photovoltaic power generation system according to the arrangement pattern of the photovoltaic components 2. That is, the number of quick-release clamps 1 can be multiple, thereby achieving the installation and fixation of multiple groups of photovoltaic components 2.

[0043] The present invention also provides a rooftop photovoltaic building integration system, including the above-mentioned quick-install clamp 1, the rooftop photovoltaic building integration system includes a support 4, the lower part of the support 4 is fixed to the factory purlin 5 on the roof, the color steel tiles are in line with the shape of the support 4 and are laid along the support 4, the laid color steel tiles are fixed and covered on the support 4, the upper part of the support 4 is provided with a quick-install clamp 1, the quick-install clamp 1 is fixed on the color steel tiles, and the photovoltaic module 2 is fixed by the quick-install clamp 1.

[0044] In this embodiment, the rooftop photovoltaic building integration system involves the setting method of color steel tiles and photovoltaic modules 2 in photovoltaic power generation of industrial plants. In view of the large fire hazard, water leakage risk and complex installation and construction of existing industrial plant photovoltaic building integration systems, a new industrial plant photovoltaic building integration system solution is proposed. The photovoltaic module 2 is installed by using a quick-release clamp 1 to effectively solve the problem of high installation and construction cost of existing industrial plant photovoltaic building integration systems, avoid the risk of leakage, and reduce the subsequent operation and maintenance costs. The combination of photovoltaic modules 2 and color steel tiles enhances the force-bearing performance of photovoltaic modules 2, making it firm and reliable and having excellent wind resistance.

[0045] Exemplarily, the support 4 includes a first support 401 and a second support 402 which are separately arranged. The first support 401 is in the shape of a trapezoid with an extended lower edge. The lower edge of the first support 401 is fixed to the factory purlin 5 by self-tapping screws 7, and multiple supports 4 can be arranged along the factory purlin 5 on the roof and distributed along the same straight line to realize the corresponding color steel tiles and photovoltaic components 2 to be erected along the length direction of the roof, and the second support 402 is fixed to the upper part of the first support 401. The second support 402 is in the shape of a protrusion with a circular arc surface, and both sides of the second support 402 are recessed inward, so that when the color steel tiles are laid along the support 4, the color steel tiles are in contact with the outer surface of the support 4 and are fixed relative to the support 4.

[0046] Among them, the color steel tile includes a first color steel tile 3 and a second color steel tile 6 distributed on both sides of the support 4. The first color steel tile 3 and the second color steel tile 6 are formed by upright lock-edge molding according to the shape of the support 4, forming an overlapping structure on the top and part of the side of the support 4, effectively preventing roof leakage.

[0047] In this embodiment, the support 4 can be formed in one piece, or it can be formed in a way that the first support 401 and the second support 402 are separately arranged; more specifically, a slot is provided on the upper surface of the first support 401, and the second support 402 includes a first positioning card 4011 and a second positioning card 4012, and the second positioning card 4012 is an elastic component, and the second positioning card 4012 can be inserted into the first positioning card 4011 to achieve assembly and fixation; during the assembly process, when the second support 402 is inserted into the first support 401, the second positioning card 4012 elastically shrinks and then pops open, and the second support 402 is positioned and fixed relative to the first support 401 by the first positioning card 4011 and the popped-up second positioning card 4012; wherein the length of the slot is greater than the length of the second support 402, and the width of the second positioning card 4012 when it pops open is greater than the width of the slot.

[0048] In this embodiment, the colored steel tiles are installed on the slope of the industrial plant. The colored steel tiles are waterproofed in the traditional way of overlapping the upper and lower colored steel tiles with upright locking edges on the left and right. Due to the application of mature technology, the problem of roof leakage caused by unreasonable design of photovoltaic building integration on the roof of existing industrial plants is avoided. The colored steel tiles are fixed by the supports 4 fixed on the purlins 5 of the plant to ensure the ability to resist wind uplift.

[0049] During the installation process of the roof photovoltaic building integrated system, first, during installation, the first support 401 is fixed to the factory purlin 5 by self-tapping screws 7. The second support 402 is elastic. During installation, the second support 402 is aligned with the slot on the upper surface of the first support 401 and pressed hard. The second positioning card 4012 of the second support 402 is elastically deformed due to the thrust of the slot wall of the first support 401, so that the first support 401 passes through the slot on the upper surface of the second support 402. Since the pop-up width of the second positioning card 4012 of the second support 402 is greater than the slot width on the upper surface of the first support 401, the connection between the second support 402 and the first support 401 can effectively resist wind lifting. At the same time, the first positioning card 4011 of the second support 402 prevents the second support 402 from continuing to slide down. The slot length of the first support 401 is greater than the length of the second support 402, thereby eliminating the influence of different thermal expansion and contraction coefficients on the system.

[0050] Next, after the second support 402 is firmly installed, the first color steel tile 3 and the second color steel tile 6 are laid and the upright lock edge forming operation is performed according to the shape of the second support 402. The first color steel tile 3 and the second color steel tile 6 form an overlapping structure along the length of the roof on the top and part of the side of the second support 402, which effectively prevents roof leakage while enhancing the lock edge strength.

[0051] The third step is to install the quick-loading clamp 1. The second positioning card 4012 of the quick-loading clamp 1 is set at an angle to the side plate 12 of the quick-loading clamp 1. The quick-loading clamp 1 is an elastic component. The second positioning card 4012 is engaged with the vertical edge formed by the locking edge of the color steel tile to ensure that the quick-loading clamp 1 will not loosen from the color steel tile under negative wind pressure. The fourth limit card 13 is stuck on the upper surface of the step of the color steel tile to prevent it from sliding down along the roof. This design avoids the operation of drilling holes in the color steel tile and greatly reduces the risk of water leakage.

[0052] The fourth step is to install the photovoltaic component 2, push the photovoltaic component 2 into the first limit card 8 and the third limit card 14, the first limit card 8 is engaged with the first card slot 16 of the component frame 17, the third limit card 14 is engaged with the second card slot 18 of the component frame 17, and the bottom plate 10 overlaps with the upper surface of the component frame 17, thereby fixing the photovoltaic component 2. No drilling is required during the installation of the photovoltaic component 2, thereby ensuring the waterproof requirements of the roof.

[0053] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

The description of the above embodiments is only used to help understand the method and core idea of ​​the present invention.
