Description

Technical Field

[0001] This utility model relates to the field of building-integrated photovoltaics (BIPV) technology, specifically to a novel BIPV roof gutter structure. Background Technology

[0002] Existing BIPV roof drainage systems all use BIPV drainage channels connected to external gutters. Based on our company's actual research, the existing drainage systems have the following problems: The water channel is installed below the roof photovoltaic modules, with a height ranging from a few centimeters to tens of centimeters. The drain outlet of the water channel rests on the external gutter. In this method, there is a gap between the upper edge of the gutter and the roof modules (caused by the height of the water channel), resulting in extremely poor airtightness. Outdoor moisture can easily enter the building. Even worse, during heavy rain, water can easily splash into the building, seriously affecting the airtightness, heat preservation, and energy efficiency of the entire building. Utility Model Content

The outer end of the first gutter is connected to a first mounting plate, and the inner end of the second gutter is connected to a second mounting plate. The photovoltaic panels are fixedly connected to the roof truss beam via photovoltaic brackets; The first mounting plate is fixedly connected to the wall column via a gutter support beam, and the gutter support beam, the first mounting plate, and the wall column are sequentially fixedly connected by screws; the connecting plate is connected to the bottom of the photovoltaic panel via a first purlin, and the photovoltaic panel, the connecting plate, and the first purlin are sequentially fixedly connected by screws; the second mounting plate is connected to the bottom of the photovoltaic bracket via a second purlin, and the photovoltaic bracket, the second mounting plate, and the second purlin are sequentially fixedly connected by screws. The bottom of the first and second ditches each has an outlet.

Detailed Implementation

[0013] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0014] As shown in the figure, a new type of BIPV roof gutter structure includes a gutter body and photovoltaic panels 10.

[0015] The gutter body includes a first gutter 1 and a second gutter 2, which are connected by a connecting plate 3. The outer end of the first gutter 1 is connected to a first mounting plate 4, and the inner end of the second gutter 2 is connected to a second mounting plate 5. The inner sides of the two sides of the first gutter 1 are connected by tie rods 6, which are fixedly connected to the inner sides of the two sides of the first gutter 1 respectively.

[0016] The first mounting plate 4 is fixedly connected to the wall column 8 via the gutter support beam 7. The gutter support beam 7, the first mounting plate 4, and the wall column 8 are sequentially fixedly connected by screws. The bottom of the first gutter 1 is provided with a gutter support 9. The photovoltaic panel 10 is fixedly connected to the roof truss beam via the photovoltaic bracket 11. The connecting plate 3 is connected to the bottom of the photovoltaic panel 10 via the first purlin 12. The photovoltaic panel 10, the connecting plate 3, and the first purlin 12 are sequentially fixedly connected by screws. The first purlin 12 is fixedly connected to the first purlin bracket 13, and the first purlin bracket 13 is fixedly connected to the upper end face of the roof truss beam. The second mounting plate 5 is connected to the bottom of the photovoltaic bracket 11 via the second purlin 14.

The second purlin 14 is fixedly connected to the second purlin bracket 15, and the second purlin bracket 15 is fixedly connected to the upper end face of the roof truss beam.

[0017] The bottom of the first ditch 1 and the second ditch 2 are respectively equipped with water outlets, and the sides of the first ditch 1 and the second ditch 2 are respectively equipped with overflow outlets. The water outlets and overflow outlets are connected to the rainwater collection system to guide the collected rainwater to the back-end treatment system.

[0018] In practical use, when rainwater falls onto the surface of the photovoltaic panel 10, most of it flows freely through the panel surface into the first gutter 1, and is then discharged through the outlet and overflow. A small amount of rainwater flows through the gaps between the photovoltaic panels 10 into the second gutter 2, and is finally discharged through the outlet and overflow. Compared with traditional external gutter structures, this design, while taking into account the characteristics of concealment, safety, and aesthetics, ensures the overall airtightness of the building, while improving the building's thermal insulation and energy-saving performance. Moreover, the gutter adopts a modular installation method, which is convenient for promotion and application in BIPV roof systems of different sizes and structural forms. It is quick to install and easy to maintain, making it particularly suitable for the highly integrated requirements of modular zero-carbon factories for green energy-saving systems.
