Description

[Technical field]

[0001] The invention relates to the technical field of photovoltaic structural components, and in particular to a quickly installed BIPV system. [Background technology]

[0002] BIPV is a branch of distributed photovoltaic power generation. In addition to rooftop photovoltaics, it can also be used for photovoltaic curtain walls, photovoltaic sunshades, photovoltaic greenhouses and other application scenarios. Photovoltaic panels not only provide power generation functions, but also serve as part of the building structure, replacing some traditional building structures such as roof panels, tiles, windows, building facades, awnings, etc. Therefore, as a new solution for building photovoltaics, BIPV has certain advantages in terms of safety, ornamental, convenience and economy: 1) BIPV does not require additional devices to fix photovoltaic equipment, and its photovoltaic components are not exposed to the outside like BAPV, which is not easily eroded by external forces and is safer; 2) BIPV integrates photovoltaic components into building materials, making the building more integrated, and can be customized by changing the color, shape and transparency of the components to make it more ornamental; 3) The deep integration of photovoltaic components and buildings improves the stability of BIPV, making its service life much longer than other distributed photovoltaics; 4) Maintenance reduces damage to existing buildings and reduces maintenance costs.

[0003] As an important component of the BIPV system, the water guide beam usually includes two types: M-shaped water guide beam and V-shaped water guide beam. It mainly plays the role of waterproofing, water guiding and structural support to ensure the stability and durability of the system. The patent CN115306091B applied by the applicant on July 29, 2022 discloses a building-integrated photovoltaic system, including a plurality of longitudinal water guide beam groups, each of which includes a plurality of water guide beams 100' arranged in the longitudinal direction, as shown in the attached figure. Figure 1 As shown, the water guide beam 100' is a V-shaped water guide beam, and the connected water guide beams 100' are overlapped, and the longitudinal water guide beam group is locked with the purlin 103' through the first fixing member 101'. When locking, first use two screws 102' to lock the first fixing member 101' on the purlin 103', and then use two screws 102' to lock the water guide beam 100' on the first fixing member 101'. The two adjacent water guide beams 100' also need to be locked with screws 102', and finally the photovoltaic module is locked on the water guide beam 100'. After long-term use, it is found that this connection method uses too many screws 102' during the installation process, which will damage the water guide beam 100' and is not conducive to the waterproofing of the water guide beam 100'; in addition, installing too many screws 102' reduces the construction efficiency, increases the construction period, and is not conducive to the convenience of later operations such as operation and maintenance.

[0044] See also Figures 3 to 13 As shown, the present invention provides a quick-installation BIPV system, including a water guide beam assembly 100, wherein the water guide beam assembly 100 includes a W-shaped water guide beam 1 and a T-shaped base 2; Figure 4As shown, the W-shaped water guide beam 1 includes an integrally formed bottom wall 11, a first side wall 12 and a second side wall 13, the first side wall 12 and the second side wall 13 respectively extend upward along both sides of the bottom wall 11 and tilt outward, and the first side wall 12, the bottom wall 11, and the second side wall 13 are surrounded to form a water guide groove 14; a fixed convex cavity 15 is formed upward in the middle of the bottom wall 11, and the fixed convex cavity 15 includes a strip cavity 151 and a circular cavity 152 that are interconnected, and the circular cavity 152 is located above the strip cavity 151 and the diameter of the circular cavity 152 is greater than the inner diameter of the strip cavity 151; as shown in the attached Figure 5 As shown, the T-shaped base 2 includes an integrally formed bottom plate 21 and a fixing rod 22, the fixing rod 22 is vertically fixedly connected to the middle of the bottom plate 21; the bottom plate 21 is provided with through holes 23 on both sides of the fixing rod 22 for fixing the T-shaped base 2 to the purlin 7; the fixing rod 22 includes a bar 221 and a round rod 222, the round rod 222 is located above the bar 221 and the diameter of the round rod 222 is greater than the diameter of the bar 221. The outer diameter of the bar 221 is equal to the inner diameter of the bar cavity 151, and the diameter of the round rod 222 is equal to the diameter of the round cavity 152, so that the fixing convex cavity 15 and the fixing rod 22 can be adapted to each other to ensure the connection stability.

[0045] The water guide beam assembly 100 of the present invention has the following beneficial technical effects:

[0046] 1. The W-shaped structure can save 25% of consumables compared with the M-shaped cross-section water guide beam.

[0047] 2. During the installation of the water guide beam assembly 100, only the T-shaped base 2 needs to be locked with the purlin 7 using the self-tapping screws 24, thereby greatly reducing the use of the self-tapping screws 24: making the construction more convenient and improving the overall installation efficiency of the water guide beam assembly 100; reducing the number of screw holes, reducing damage to the product itself, and being more conducive to waterproofing; making subsequent operations such as operation and maintenance more convenient.

[0048] In the present invention, the W-shaped water guide beam 1 is a W-shaped carbon steel water guide beam made of carbon steel. Carbon steel water guide beams made of carbon steel are more resilient than traditional aluminum alloy water guide beams. Figure 6As shown, it includes a first W-shaped carbon steel water guide beam and a second W-shaped carbon steel water guide beam spliced ​​up and down. When splicing is required, the strip cavity 151 of the upper first W-shaped carbon steel water guide beam is aligned with the outside of the circular cavity 152 of the lower second W-shaped carbon steel water guide beam, and the first W-shaped carbon steel water guide beam is pressed down to enlarge the strip cavity 151. Finally, the circular cavity 152 of the second W-shaped carbon steel water guide beam is inserted into the circular cavity 152 of the first W-shaped carbon steel water guide beam. Since the W-shaped carbon steel water guide beam has high toughness, the first W-shaped carbon steel water guide beam can tightly clamp the second W-shaped carbon steel water guide beam. At this time, the first W-shaped carbon steel water guide beam and the second W-shaped carbon steel water guide beam can only slide in the length direction but not in the width direction.

[0049] In the present invention, the through hole 23 is a strip-shaped through hole. By designing the through hole 23 of the T-shaped base 2 to be a strip-shaped through hole, the T-shaped base 2 can be fine-tuned left and right, and then locked with the self-tapping screws 24.

[0050] In the present invention, as shown in the attached Figure 6-11 As shown, it also includes an improved clamp assembly 200 for clamping and fixing the water guide beam assembly 100 and supporting the BIPV photovoltaic assembly 9. The improved clamp assembly 200 can be clamped at any position in the length direction of the water guide beam assembly 100. Since there will be slight sliding in the length direction when adjacent W-shaped carbon steel water guide beams are spliced, the improved clamp assembly 200 can be set to clamp the splicing to avoid sliding in the length direction, replacing the locking method of the self-tapping screws 24 used in the traditional installation process at this step, reducing the use of the self-tapping screws 24 and improving the installation efficiency.

[0051] In the present invention, as shown in the attached Fig. 9 As shown, the improved clamp assembly 200 includes a first S-shaped clamp block 3, a second S-shaped clamp block 4, and a first flange nut 5 and an external polygonal bolt 6 for locking the first S-shaped clamp block 3 and the second S-shaped clamp block 4; the first S-shaped clamp block 3 includes a first top plate 31, a first S-shaped plate 32, and a first bottom plate 33; the upper end of the first S-shaped plate 32 is fixedly connected to the left end of the first top plate 31, and the lower end is fixedly connected to the right end of the first bottom plate 33; the first top plate 31 is penetrated by a circular hole 311 for the external polygonal bolt 6 to pass through, and the bottom surface of the first top plate 31 is formed with a bolt groove 312. The first top plate 31 is a horizontal plate, used to cooperate with the second top plate 41; the first S-shaped plate 32 is used to cooperate with the fixed convex cavity 15; the first bottom plate 33 is used to cooperate with the bottom wall 11 of the W-shaped water guide beam 1. When clamped, the first bottom plate 33 abuts against the bottom wall 11, and the lower end of the first S-shaped plate 32 abuts against the outside of the strip cavity 151 of the fixed convex cavity 15.

[0052] As attached Fig.10As shown, the second S-shaped clamp block 4 includes a second top plate 41, a second S-shaped plate 42, and a second bottom plate 43; the bending direction of the second S-shaped plate 42 is opposite to that of the first S-shaped plate 32, the upper end of the second S-shaped plate 42 is fixedly connected to the right end of the second top plate 41, and the lower end is fixedly connected to the left end of the second bottom plate 43; the second top plate 41 is formed with a long strip hole 411 for the outer polygonal bolt 6 to pass through and to match the round hole 311, and the left and right ends of the top surface of the second top plate 41 are respectively fixed with a first support seat 44 and a second support seat 45. The second top plate 41 is a horizontal plate for matching with the first top plate 31; the second S-shaped plate 42 is used to match with the fixed convex cavity 15; the second bottom plate 43 is used to match with the bottom wall 11 of the W-shaped water guide beam 1, and when clamped, the second bottom plate 43 abuts against the bottom wall 11, and the lower end of the second S-shaped plate 42 abuts against the outside of the strip cavity 151 of the fixed convex cavity 15. The first support base 44 and the second support base 45 are used to support the BIPV photovoltaic assembly 9 .

[0053] Preferably, the external polygonal bolt 6 is an external hexagonal bolt.

[0054] In the present invention, the upper end of the first S-shaped plate 32 and the first top plate 31 are surrounded to form a first half-slot 34, and the upper end of the second S-shaped plate 42 and the second top plate 41 are surrounded to form a second half-slot 46; when the first S-shaped clamp block 3 and the second S-shaped clamp block 4 are combined, the second top plate 41 is pressed on the first top plate 31, and the first half-slot 34 and the second half-slot 46 are surrounded to form a convex cavity accommodating groove of the circular cavity 152, and the lower end of the first S-shaped plate 32 and the lower end of the second S-shaped plate 42 are respectively pressed on both sides of the strip cavity 151. The present invention mainly clamps both sides of the strip cavity 151 of the W-shaped water guide beam 1 by the lower end of the first S-shaped plate 32 and the lower end of the second S-shaped plate 42. The first S-shaped clamp block 3 and the second S-shaped clamp block 4 constitute a detachable improved clamp assembly 200, so the design of the first half-slot 34 and the second half-slot 46 is convenient for installation and clamping.

[0055] In the present invention, the length direction of the long hole 411 is arranged along the first support seat 44 toward the second support seat 45, so that the first S-shaped clamp block 3 and the second S-shaped clamp block 4 can be adjusted left and right to adapt to fixed convex cavities 15 of different sizes.

[0056] In the present invention, one end of the second top plate 41 away from the second S-shaped plate 42 is tilted downward to form a limit plate 47, and the tilt direction of the limit plate 47 is the side away from the second S-shaped plate 42. The design of the limit plate 47 can assist the first S-shaped clamping block 3 in guiding during installation, and can also limit the outward movement of the first S-shaped clamping block 3, so that the first S-shaped clamping block 3 and the second S-shaped clamping block 4 are more firmly and stably combined.

[0057] As attached Figure 11-13As shown, in the present invention, the installation of the BIPV system includes the following steps:

[0058] Step 1: Use self-tapping screws 24 to lock the T-shaped base 2 onto the purlin 7;

[0059] Step 2: The fixed convex cavity 15 is aligned with the fixed rod 22, and the W-shaped water guide beam 1 is pressed into the T-shaped base 2; adjacent W-shaped water guide beams 1 are spliced, and the strip cavity 151 of the second W-shaped water guide beam 1 is aligned with the circular cavity 152 of the first W-shaped water guide beam 1, and the fixed convex cavity 15 of the second W-shaped water guide beam 1 is pressed into the fixed convex cavity 15 of the first W-shaped water guide beam 1 through the toughness deformation of the W-shaped water guide beam 1; the contact surfaces of adjacent W-shaped water guide beams 1 are coated with waterproof structural glue or mastic, which is conducive to waterproofing and water leakage prevention;

[0060] Step 3: Use the improved clamp assembly 200 to lock the W-shaped water guide beam 1;

[0061] Step 4: Place the horizontal water trough 8 on the two W-shaped water guide beams 1, and then place the two BIPV photovoltaic modules 9 on the first support seat 44 and the second support seat 45 respectively, and then press the waterproof cover plate 10 on the two BIPV photovoltaic modules 9, and then press the middle pressure block 101 on the waterproof cover plate 10, and finally use the second flange nut 102 to lock it. The waterproof cover plate 10 can cover the gap between the two BIPV photovoltaic modules 9 to reduce the inflow of rainwater. The second flange nut 102 matches the middle pressure block 101, and the waterproof cover plate 10 is pressed tightly on the BIPV photovoltaic module 9.

[0062] Preferably, in step three, the external polygonal bolt 6 is first inserted into and passed through the circular hole 311 from the bottom surface of the first top plate 31, the bolt head of the external polygonal bolt 6 is inserted into the bolt groove 312, and then the first S-shaped clamp 3 is pressed against the outside of the strip cavity 151; the external polygonal bolt 6 then passes through the long hole 411, the second S-shaped clamp 4 is pressed against the outside of the strip cavity 151 and the second top plate 41 is fitted with the first top plate 31, and the first flange nut 5 is used to lock the first S-shaped clamp 3 and the second S-shaped clamp 4.

[0063] Preferably, in step four, a grounding plate is installed between the first support base 44 and the BIPV photovoltaic assembly 9 , and a grounding plate is installed between the second support base 45 and the BIPV photovoltaic assembly 9 .

[0064] In the present invention, the external polygonal bolt 6 passes through the circular hole 311, the long hole 411, the first flange nut 5, the gap between the two BIPV photovoltaic components 9, the waterproof cover plate 10, the middle pressure block 101, and the second flange nut 102 from bottom to top.

[0065] Since the installation steps of the BIPV system of the present invention omit the installation of many self-tapping screws 24, compared with the traditional method, the installation speed is faster and more efficient, and the complexity of subsequent operations such as operation and maintenance is reduced.

[0066] Although the specific implementation modes of the present invention are described above, those skilled in the art should understand that the specific implementation modes described are only illustrative and are not intended to limit the scope of the present invention.
