Description

TECHNICAL FIELD

[0001] The utility model relates to photovoltaic technology field, concretely relates to a new type water guide beam subassembly for BIPV system. BACKGROUND

[0002] BIPV combines solar photovoltaic panels with buildings to achieve photovoltaic building integration, which is a branch of distributed photovoltaic power generation. In addition to roof photovoltaics, it can also be used as 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 traditional building structures such as roof panels, tiles, windows, building facades, and rain shelters. Therefore, BIPV, as a new solution for building photovoltaics, has certain advantages in safety, aesthetics, convenience, and economy: 1) BIPV does not require additional devices to secure photovoltaic equipment, and its photovoltaic components are not exposed like BAPV, making them less susceptible to external erosion and more secure; 2) BIPV integrates photovoltaic components into building materials, making the building more cohesive and allowing for customized design through changes in component color, shape, and transparency, making it more aesthetically pleasing; 3) The deep integration of photovoltaic components with buildings improves the stability of BIPV, resulting in a significantly longer service life than other distributed photovoltaics; 4) Maintenance reduces damage to existing buildings and lowers maintenance costs.

[0003] As an important component of BIPV systems, existing water guide beams typically include M-type water guide beams and V-type water guide beams, primarily serving the functions of waterproofing, water guiding, and structural support to ensure system stability and durability. The CN115306091B patent, filed by the applicant on July 29, 2022, discloses a building-integrated photovoltaic system, which includes several longitudinal water guide beam groups. Each longitudinal water guide beam group includes several water guide beams 100' arranged longitudinally. As shown in the accompanying drawings, the water guide beam 100' is a V-type water guide beam, and the adjacent water guide beams 100' are connected using lap joints. The longitudinal water guide beam group is locked to the purlin 103' using the first fixing member 101'. During locking, two screws 102' are used to lock the first fixing member 101' to the purlin 103', and two screws 102' are used to lock the water guide beam 100' to the first fixing member 101'. The adjacent two water guide beams 100' also need to be locked using screws 102'. Finally, the photovoltaic components are locked to the water guide beam 100'. Figure 1 After long-term use, it was found that this connection method uses too many screws 102' during installation, which can damage the water guide beam 100' and is not conducive to waterproofing. Additionally, the excessive installation of screws 102' reduces construction efficiency, increases construction cycle time, and is not conducive to the convenience of post-operation and maintenance.

[0032] In the installation process of the utility model's water guide beam assembly 100, only T type base 2 needs to be locked with purlin 4 using self-tapping screw 3, and the connection between W type water guide beam 1 and T type base 2 does not need self-tapping screw 3, so that the use amount of self-tapping screw 3 is greatly reduced, and in addition, W type water guide beam 1 does not need to be punched, the number of screw hole openings is reduced, the damage to the product itself is reduced, and it is more conducive to the waterproofness of W type water guide beam 1.
