Description

Technical field

[0001] The utility model relates to the technical field of photovoltaics, and in particular to a water guide beam clamp component applied to a BIPV system. [Background Technology]

[0002] BIPV combines solar photovoltaic panels with buildings to achieve photovoltaic-building integration. It is a branch of distributed photovoltaic power generation. In addition to rooftop photovoltaics, it can also be used in photovoltaic curtain walls, photovoltaic sunshades, photovoltaic greenhouses, and other application scenarios. The 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, and awnings. Therefore, as a new solution for building photovoltaics, BIPV has certain advantages in terms of safety, aesthetics, convenience, and economy: 1) BIPV does not require additional devices to fix photovoltaic equipment, and its photovoltaic modules are not exposed to the outside like BAPV, so they are not easily corroded by external forces and are safer. 2) BIPV integrates photovoltaic modules into building materials, making the building more integrated. The module can be customized by changing its color, shape, and transparency, making it more aesthetically pleasing. 3) The deep integration of photovoltaic modules and buildings improves the stability of BIPV, making its service life far longer than other distributed photovoltaic systems. 4) Maintenance reduces damage to existing buildings, reducing maintenance costs.

[0003] As an important component of the BIPV system, the water guide beam clamp assembly plays the role of clamping the water guide beam and supporting the BIPV photovoltaic module. The applicant applied for patent CN115306091B on July 29, 2022, which discloses a building integrated photovoltaic system, as shown in the attached Figure 1 and 2 As shown, it includes a water guide beam 100', a base plate 101', and a first fixing member 103'. The base plate 101' is fixed to the water guide beam 100' by self-tapping screws 102', and the connected water guide beams 100' are connected by upper and lower splicing. When locking, first use two self-tapping screws 102' to lock the first fixing member 103' to the purlin, and then use two self-tapping screws 102' to lock the base plate 101', the water guide beam 100', and the first fixing member 101'. The two adjacent water guide beams 100' also need to be locked using self-tapping screws 102'. This connection method uses too many self-tapping screws 102' during the installation process, requiring punching holes in the water guide beam 100', which will damage the water guide beam 100' and is not conducive to the waterproofing of the water guide beam 100'; the pad 101' will arch up after long-term use, and thus the overall strength is not high; in addition, the excessive installation of self-tapping screws 102' reduces construction efficiency, increases the construction period, and is not conducive to the convenience of subsequent operation and maintenance.

In addition, the terms "first," "second," and the like are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly specifying the number of the technical features indicated. Therefore, features defined as "first," "second," and the like may explicitly or implicitly include one or more of such features.

[0036] See also Figures 3 to 10As shown, the present invention provides a water guide beam clamp assembly 100 for use in a BIPV system. The assembly comprises a first S-shaped clamp block 1, a second S-shaped clamp block 2, and a first flange nut 3 and an external polygonal bolt 4 for locking the first and second S-shaped clamp blocks 1, 2. The first S-shaped clamp block 1 is curved in the opposite direction to the second S-shaped clamp block 2. The first S-shaped clamp block 1 forms a first half-slot 11, while the second S-shaped clamp block 2 forms a second half-slot 21. When the first and second S-shaped clamp blocks 1, 2 are assembled, the first and second half-slots 11, 21 enclose a clamping groove 5 for the water guide beam 6. During pre-assembly of the water guide beam clamp assembly 100, the external polygonal bolt 4 is first inserted through the bottom surface of the first S-shaped clamp block 1 and then through the second S-shaped clamp block 2. After the fixing rod 72 of the water guide beam 6 is clamped into the clamping groove 5, the first flange nut 3 is used to lock the first and second S-shaped clamp blocks 1, 2. The water guide beam clamp assembly 100 of the present invention mainly relies on the lower ends of the first S-shaped clamping block 1 and the second S-shaped clamping block 2 to press against both sides of the cavity 651 of the water guide beam 6 to achieve the clamping operation on the water guide beam 6.

[0037] The water guide beam clamp assembly 100 of the present invention is used to tighten and fix the water guide beam 6 and support the BIPV photovoltaic module, and has at least the following beneficial technical effects:

[0038] 1. The water guide beam clamp assembly 100 can be clamped at any position in the length direction of the water guide beam 6. Since the water guide beam 6 may slide slightly in the length direction when adjacent water guide beams 6 are spliced ​​up and down, the water guide beam clamp assembly 100 of the present invention can be set to clamp the splicing position to avoid sliding in the length direction. This replaces the traditional installation process of using self-tapping screws in this step, reduces the use of self-tapping screws, and improves installation efficiency.

[0039] 2. Since there is no need to punch holes in the water guide beam 6 , damage to the water guide beam 6 is avoided, which is beneficial to the waterproofing of the water guide beam 6 .

[0040] 3. Compared with the pads used in the prior art, the water guide beam clamp assembly 100 will not deform or arch after long-term use, so the overall strength is higher.

[0041] 4. The first S-shaped clamping block 1 and the second S-shaped clamping block 2 constitute a detachable water guide beam clamp assembly 100. The design of the first half slot 11 and the second half slot 21 facilitates the clamping of water guide beams 6 of different sizes.

[0042] In the present utility model, as shown in the attached Figure 5As shown, the first S-shaped clamping block 1 includes a first top plate 12, a first S-shaped plate 13, and a first bottom plate 14.

The first top plate 12 is formed with a circular hole 15 for the external polygonal bolt 4 to pass through, and the bottom surface of the first top plate 12 is formed with a bolt slot 16. The first top plate 12 is a horizontal plate, which is used to mate with the second top plate 22. The first S-shaped plate 13 is used to mate with the fixed convex cavity 65 of the water guide beam 6. The first bottom plate 14 is used to mate with the bottom wall 61 of the water guide beam 6. When clamped, the first bottom plate 14 abuts against the bottom wall 61, and the lower end of the first S-shaped plate 13 abuts against the outside of the bar cavity 651 of the fixed convex cavity 65.

[0043] In the present utility model, as shown in the attached Figure 6 As shown, the second S-shaped clamping block 2 includes a second top plate 22, a second S-shaped plate 23, and a second bottom plate 24. The upper end of the second S-shaped plate 23 is fixedly connected to the right end of the second top plate 22, and the lower end is fixedly connected to the left end of the second bottom plate 24. The second top plate 22 is formed with an elongated hole 25 through which the external polygonal bolt 4 passes and which mates with the circular hole 15. The second top plate 22 is a horizontal plate, adapted to mate with the first top plate 12. The second S-shaped plate 23 is adapted to mate with the fixed convex cavity 65 of the water guide beam 6. The second bottom plate 24 is adapted to mate with the bottom wall 61 of the water guide beam 6. When clamped, the second bottom plate 24 abuts against the bottom wall 61, and the lower end of the second S-shaped plate 23 abuts against the outside of the strip cavity 651 of the fixed convex cavity 65.

[0044] In the present invention, the length direction of the long hole 25 is set along the first support seat 27 toward the second support seat 28, so that the first S-shaped clamping block 1 and the second S-shaped clamping block 2 can be adjusted left and right to adapt to fixed convex cavities 65 of different sizes.

[0045] In the present invention, the end of the second top plate 22 facing away from the second S-shaped plate 23 extends downwardly and obliquely to form a limit plate 26, and the oblique direction of the limit plate 26 is toward the side facing away from the second S-shaped plate 23. The design of the limit plate 26 can assist in guiding the first S-shaped clamping block 1 during installation and can also limit the outward movement of the first S-shaped clamping block 1, making the combination of the first S-shaped clamping block 1 and the second S-shaped clamping block 2 more secure and stable.

[0046] In the present invention, a first support base 27 and a second support base 28 are fixedly mounted on the left and right ends of the top surface of the second top plate 22, respectively. The first support base 27 includes a first support vertical plate and a first support horizontal plate. The bottom end of the first support vertical plate is vertically fixedly connected to the second S-shaped plate 23, and one end of the first support horizontal plate is vertically fixedly connected to the top of the first support vertical plate. The second support base 28 includes a second support vertical plate and a second support horizontal plate. The bottom end of the second support vertical plate is vertically fixedly connected to the second S-shaped plate 23, and one end of the second support horizontal plate is vertically fixedly connected to the top of the second support vertical plate. The first support base 27 and the second support base 28 are used to support BIPV photovoltaic modules.

[0047] In the present invention, the external polygonal bolt 4 is an external hexagonal bolt.

[0048] In the present utility model, as shown in the attached Figure 7-9 As shown, the water guide beam clamp assembly 100 is an aluminum alloy water guide beam clamp assembly 100 made of aluminum alloy.

[0049] In the present utility model, as shown in the attached Figure 8 As shown, the water guide beam 6 includes a bottom wall 61, a first side wall 62 and a second side wall 63. The first side wall 62 and the second side wall 63 extend upward along both sides of the bottom wall 61 and tilt outward. The first side wall 62, the bottom wall 61 and the second side wall 63 are arranged to form a water guide groove 64. A fixed convex cavity 65 is formed upward in the middle of the bottom wall 61. The fixed convex cavity 65 includes a strip cavity 651 and a circular cavity 652 that are interconnected. The circular cavity 652 is located above the strip cavity 651 and the diameter of the circular cavity 652 is larger than the inner diameter of the strip cavity 651. As shown in the attached figure Figure 9 As shown, it also includes a base 7 for connecting the water guide beam 6, the base 7 includes a bottom plate 71 and a fixing rod 72, the fixing rod 72 is vertically fixed to the middle of the bottom plate 71; the bottom plate 71 is provided with through holes on both sides of the fixing rod 72 for fixing the base 7 to the purlin; the fixing rod 72 includes a bar 721 and a round rod 722, the round rod 722 is located above the bar 721 and the diameter of the round rod 722 is larger than the diameter of the bar 721.

[0050] The water guide beam 6 is a W-shaped carbon steel structure. This W-shaped structure saves 25% of consumable materials compared to M-shaped cross-sections. During installation, only the base 7 needs to be fastened to the purlins using self-tapping screws, significantly reducing the number of self-tapping screws used. This makes installation more convenient and improves overall installation efficiency. It also reduces the number of screw holes required, minimizing damage to the product and improving waterproofing. It also facilitates subsequent maintenance and operations.
