Description

Photovoltaic modules are used as building components or building materials, making them part of the building and also having the function of generating electricity.

[0003] Currently, architects and designers are increasingly using BIPV as part of architectural design to achieve a fusion of aesthetics and technology. However, for arched roofs, such as barn roofs, the following difficulties are encountered in actual use: (1) Structural complexity. Arched roofs usually have more complex geometric shapes than flat roofs, which makes it difficult to install photovoltaic panels. At the same time, the lack of effective fixing and limiting measures makes it difficult to maintain and replace photovoltaic panels, resulting in high installation and maintenance costs; (2) Poor fit. The curvature matching between photovoltaic panels and arched roofs is poor, resulting in visual incoherence. The installation of photovoltaic panels is difficult to adapt to arched roofs of different curvatures and shapes, affecting the appearance; (3) Poor wind resistance. Due to the poor fit between photovoltaic panels and arched roofs and the limited installation firmness of photovoltaic panel clamping devices, photovoltaic panels are difficult to withstand strong winds and are easily displaced or fall off; (4) The installation position adjustment of photovoltaic panel clamps is relatively limited, which restricts the installation of photovoltaic panels at different positions and angles.

[0034] The following is combined with Figure 1-9 This application is described in further detail.

[0035] One or more embodiments of the present application disclose a photovoltaic installation device, referring to Figure 2-Figure 7 The photovoltaic installation device 1 includes a fixing component 10, a clamping component 20 and a support 40. The support 40 is laid obliquely along the roof 5. The fixing component 10 is placed on the support 40. The fixing component 10 includes a first fixing member 11 and a second fixing member 12. The first fixing member 11 is adjustably connected to the second fixing member 12 and the support 40. The two side surfaces of the support 40 are suitable for being tightly combined with the roof 5 and the first fixing member 11 respectively. The second fixing member 12 is provided with a retaining portion 127 and a clamping portion 122. The clamping portion 122 extends from the retaining portion 127 toward the direction of the photovoltaic component 2. The clamping component 20 includes a pressing plate 21. The pressing plate 21 is fixed to the retaining portion 127 by a first fastener 22. The end of the pressing plate 21 and the clamping portion 122 are relatively arranged to form a clamping area 124. The clamping area 124 is suitable for installing the frame 3 of the photovoltaic component 2. Thus, by increasing the adjustable range of the fixing component 10 on the support 40, it is helpful to adjust the position of the photovoltaic component 2 on the arched roof 5 and better adapt to the curvature and shape of the arched roof 5, regardless of whether the roof is slightly arched or more steeply curved, allowing the operator to make a wider range of adjustments within a limited space, facilitating flexible installation, reducing the need for customized components, and reducing overall installation costs.

[0036] In some embodiments, the first fixing member 11 includes a first fixing portion 111 and a positioning portion 112, the positioning portion 112 extends outward from the bottom of the first fixing portion 111 in the direction of the support 40, the support 40 is provided with an adjustment hole 41, the adjustment hole 41 is opened on the upper surface of the support 40 along the tilt direction of the photovoltaic component 2, and the positioning portion 112 is adjustably fixed to the adjustment hole 41 of the support 40, so that the first fixing member 11 can adjust the tilt position of the photovoltaic component 2 along the adjustment hole 41 of the support 40, such as Figure 4 and Figure 5 As shown, it helps to break the installation limitations of the photovoltaic installation device 1. It does not require two purlin structures, one main horizontal and one secondary vertical, so that the photovoltaic installation device 1 can be adjusted without bolt spacing restrictions, thereby reducing the installation cost of the photovoltaic module 2 on the arched roof 5.

[0037] In some embodiments, the adjustment hole 41 is waist-shaped, and the length of the adjustment hole 41 is greater than the positioning portion 112, which is suitable for adjusting the position of the photovoltaic component 2 along the tilt direction, so that the installation of the photovoltaic component 2 is more in line with the arched roof 5. Figure 6 shown.

[0038] In some embodiments, the photovoltaic installation device 1 further includes a second fastener 131 and a third fastener 132, the second fixing member 12 further includes a second fixing portion 121, the retaining portion 127 is located at the upper portion of the second fixing portion 121, the second fixing portion 121 and the first fixing portion 111 are arranged relative to each other, and the first fixing portion 111 is fixedly connected to the second fixing portion 121 through the second fastener 131, and the third fastener 132 is fixedly connected to the positioning portion 112 and the adjustment hole 41 of the support 40, so that the first fixing member 11 maintains the inclined position of the second fixing member 12, which is suitable for the inclined installation of the photovoltaic component 2 along the arched roof 5. Among them, the second fixing part 121 and the first fixing part 111 are at least partially in contact with each other, and the second fixing part 121 can be adjusted up and down relative to the first fixing part 111. When the second fixing part 121 and the first fixing part 111 are fully in contact with each other, the second fixing member 12 is in a low position. When it is necessary to adjust the position of the second fixing member 12 upward, the second fixing part 121 can be moved relatively upward along the first fixing part 111, so that the second fixing part 121 and the first fixing part 111 are partially in contact with each other, thereby adjusting the position of the photovoltaic component 2.

[0039] In some embodiments, the retaining portion 127 is provided with a fixing groove 125, which is located in the middle of the second fixing member 12, and the two clamping portions 122 extend outward from both sides of the retaining portion 127. The pressure plate 21 includes a pair of connecting sections 211, a pair of extension sections 212 and a locking section 213. The connecting sections 211 are integrally connected to the extension sections 212 upward from both ends of the locking section 213, and the extension sections 212 on both sides are arranged in different directions. The locking sections 213 are abutted against the top of the retaining portion 127 of the second fixing member 12. The first fastener 22 fixes the locking section 213 of the pressure plate 21 and the fixing groove 125 of the retaining portion 127 to lock the pressure plate 21 and the second fixing member 12, so that a semi-enclosed clamping area 124 is formed between each extension section 212 and the clamping portion 122, and the long side frame 3 of the photovoltaic module 2 is clamped between the extension section 212 and the clamping portion 122. It is worth mentioning that the long side of the photovoltaic module 2 is located at the opening of the clamping area 124, which helps to set multiple photovoltaic installation devices 1 along the long side of the photovoltaic module 2 under the condition that the long side of the photovoltaic module 1 is arranged horizontally along the roof 5, which can provide a more uniform force distribution and enhance the stability of the overall structure. At the same time, combined with the short side of the photovoltaic module 2 being inclined along the arched roof 5, such as Figure 2 As shown, the inclination angle of the photovoltaic module 2 can be adjusted through the adjustment hole 41 of the support 40, thereby improving the fit between the photovoltaic module 2 and the arched roof 5 and enhancing the curve fitting between the photovoltaic module 2 and the arched barn metal tile 4, thereby maximizing the use of the arched roof 5 space and increasing the installation capacity, thereby improving the overall energy output.

[0040] In some embodiments, the pressing plate 21 is concave, the locking section 213 is located on the concave surface, the height of the connecting section 211 is suitable for the installation of the frame 3, and the height of the connecting section 211 can be small, so that the clamping area 124 is suitable for installing the C-shaped frame 3. Figure 3 The height of the connecting section 211 can also be larger, so that the clamping area 124 is suitable for installing a higher frame 3, such as Figure 8 shown.

[0041] In some embodiments, the second fixing member 12 further includes a limiting portion 14, which extends from at least one of the clamping portions 122 toward the clamping area 124. The limiting portion 14 is located between the connecting section 211 of the pressing plate 21 and the frame 3, so that the side of the limiting portion 14 supports and limits the frame 3 of the photovoltaic module 2, preventing the pressing plate 21 from becoming loose due to direct squeezing interference of the photovoltaic module 2, resulting in the displacement of the photovoltaic module 2. Thus, through the optional adjustment of the second fastener 131 along the height direction and the third fastener 132 along the tilt direction, the multi-degree-of-freedom limiting fixation is increased, the fit between the photovoltaic module 2 and the arched roof 5 is improved, the loosening risk of the pressing plate 21 is reduced, and the movement and vibration of the photovoltaic module 2 are effectively reduced, thereby further reducing the maintenance cost and potential damage risk, while being easy to install and having high installation efficiency.

[0042] In some embodiments, the second fixing member 12 further includes a support portion 123 and a rubber strip 126, the support portion 123 extends from the clamping portion 122 in a direction away from the second fixing portion 121, and the rubber strip 126 is laid in the support portion 123 to be supported below the photovoltaic module 2. In other words, the upper surface of the rubber strip 126 of the support portion 123 is in contact with the lower surface of the photovoltaic module 2, so as to further support the photovoltaic module 2, which is beneficial to reduce the span of the suspended part of the photovoltaic module 2, so that part of the load on the photovoltaic module 2 is shared by the support portion 123, thereby improving the carrying capacity of the photovoltaic module 2.

[0043] In some embodiments, the rubber strip 126 can be made of a flexible layer, such as EPDM rubber, which has weather resistance and electrical insulation properties. It is worth mentioning that when the rubber strip 126 is made of a flexible layer, it is placed between the support portion 123 and the photovoltaic module 2 to buffer the pressure on the photovoltaic module 2, further improving the load resistance of the photovoltaic module 2. It is understandable that the rubber strip 126 can also be set in the frame 3 to reduce the contact between the photovoltaic module 2 and the metal surface of the frame 3, thereby reducing the wear or scratches and generating electrochemical corrosion, such as Fig. 9 shown.

[0044] In some embodiments, the photovoltaic installation device 1 is further provided with a serrated belt 30, which is formed on the upper surface of the clamping portion 122 and / or the lower surface of the extension section 212 of the pressure plate 21 arranged relative to the clamping portion 122. Specifically, the serrated belt 30 can be formed on the upper surface of the clamping portion 122, adapted to be installed on the bottom surface of the frame 3 of the photovoltaic module 2, and the serrated belt 30 can also be formed on the lower surface of the extension section 212 of the pressure plate 21, adapted to be installed on the top surface of the frame 3 of the photovoltaic module 2. The serrated belt 30 allows the frame 3 to be limited and connected more tightly with the pressure plate 21 and the clamping portion 122, with better anti-slip and anti-falling performance, and improved wind resistance.

[0045] In some embodiments, the support 40 is a Z-shaped connector, and a pair of engagement holes 42 are provided on the lower surface of the support 40. The engagement holes 42 are fixedly connected to the support 40 and the metal tile 4 of the roof 5 by fasteners, such as Figure 7 As shown. Among them, the Z-shaped connector can provide a certain degree of adjustment space, allowing the position and angle of the photovoltaic module 2 to be fine-tuned during installation, and flexibly adapting to the arched roof 5 with different tilt angles and shapes. At the same time, the tilt position of the fixing component 10 is adjusted in combination with the adjustment hole 41 of the support 40 along the tilt direction of the photovoltaic module 2, and the long side of the photovoltaic module 2 can be arranged horizontally, avoiding the difficulty in adjusting the position of the photovoltaic module 2 due to the fixing spacing of the barn bolts, and also avoiding the situation where the module of the photovoltaic module 2 is not uniform.

[0046] In some embodiments, the limiting portion 14 includes a first limiting portion 141 and a second limiting portion 142, and the first limiting portion 141 and the second limiting portion 142 respectively protrude upward from the clamping portions 122 on both sides to form a receiving groove 144 adapted to the pressing plate 21. When the locking section 213 of the pressing plate 21 is received in the receiving groove 144, the first limiting portion 141 and the second limiting portion 142 respectively abut against both sides of the locking section 213, wherein the receiving groove 144 is communicated with the fixing groove 125 and is fastened by the first fastener 22, which helps to limit the frame 3, such as Figure 4 .

[0047] In some embodiments, the limiting portion 14 includes a first limiting portion 141 and a second limiting portion 142, and the clamping portion 122 includes a first clamping portion 128 and a second clamping portion 129. The first clamping portion 128 is located at the lower side of the second fixing member 12 relative to the retaining portion 127, and the second clamping portion 129 is located at the upper side of the second fixing member 12 relative to the retaining portion 127. The first limiting portion 141 is bent from the end of the first clamping portion 128 to extend toward the frame 3, and a limiting groove 143 is formed in the first limiting portion 141. The limiting groove 143 is suitable for hanging the baffle 6 of the frame 3, so as to limit the position of the frame 3 in the clamping area 124 on the lower side to prevent the frame 3 from being offset or detached from the clamping area 124. The second limiting portion 142 extends from the second clamping portion 129 to the pressure plate 21, and the second limiting portion 142 abuts against the side of the frame 3, so as to support the frame 3 of the upper photovoltaic component 2 from the side and limit it. Fig. 9 shown.

[0048] One or more embodiments of the present application disclose a photovoltaic system, referring to Figure 1 As shown, the photovoltaic system includes the photovoltaic installation device 1, metal tiles 4 and photovoltaic modules 2 as above. The lower surface of the support 40 is fixedly connected to the metal tiles 4 of the roof 5 by fasteners. The photovoltaic modules 2 are installed obliquely in the adjacent photovoltaic installation device 1. After the installation is completed, the metal tiles 4, the photovoltaic installation device 1 and the photovoltaic modules 2 form a whole. When subjected to wind force or external shaking, the photovoltaic modules 2, the photovoltaic installation device 1 and the metal tiles 4 are subjected to force as a whole, which can effectively improve the structural stability and wind-resistant performance of the photovoltaic system.

[0049] In some embodiments, the long sides of the photovoltaic components 2 are arranged horizontally along the roof 5, and the short sides of the photovoltaic components 2 are arranged obliquely longitudinally along the roof 5. Multiple photovoltaic mounting devices 2 are fixed to the metal tiles 4 of the roof 5 at intervals along the long sides of the photovoltaic components 2. The frame 3 of the long side of the photovoltaic component 2 is clamped in the clamping area 124 of the photovoltaic mounting device 1. The inclination position and angle of the photovoltaic component 2 can be adjusted through the photovoltaic mounting device 1, so that the curve fitting degree between the photovoltaic component 2 and the arched roof 5 is high. At the same time, each photovoltaic component 2 is helped to enhance the anti-wind-lifting performance and reduce wind resistance through multiple photovoltaic mounting devices 1. The design of the photovoltaic component 2 that is highly fitted to the roof 5 can also reduce wind resistance and reduce the impact of wind load, especially in high wind speed areas. This helps to improve system safety and reduce maintenance costs.
