Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic architecture, and particularly relates to a side-outlet building photovoltaic integrated profile system. Background Technique

[0002] Building integrated photovoltaic (BIPV) is a technology that integrates solar power generation (photovoltaic) products into buildings. It provides electricity by installing photovoltaic modules on the surface of the building's envelope structure, and these modules also serve as functional parts of the building structure, replacing some traditional building structures such as roof panels, tiles, windows, building facades, and rain shelters. BIPV has significant environmental protection, energy-saving, and aesthetic features. It can reduce the dependence on traditional fossil fuels, help reduce the energy consumption and carbon dioxide emissions of buildings, and improve the environmental friendliness of buildings.

[0003] Currently, BIPV modules adopt a complex fastener system, which is difficult to install and not easy to connect with the existing roof structure system. Moreover, the MC4 connectors of the photovoltaic modules are likely to fall into the roof rainwater gutter, causing rainwater immersion, leading to the risks of electric leakage and high-voltage DC arcing, and also inconvenient for maintenance and management.

[0004] To solve the above problems, we made improvements and proposed a side-outlet building photovoltaic integrated profile system. Content of the Utility Model

[0005] To solve the above technical problems, the utility model provides the following technical solutions:

[0006] The utility model provides a side-outlet building photovoltaic integrated profile system, including an installation bracket. The bottom surface of the installation bracket is fixedly connected with a profile support. Serrated strengthening surfaces are arranged on both extended edges of the bottom surface and the outer side of the vertical extended edge of the installation bracket. There are two raised groove lines on the inner sides of both vertical extended edges of the installation bracket.

[0007] The top surface of the installation bracket is snap-connected with a cover plate, and a DC wire channel for the PV DC cable and the MC4 DC connector is formed between the installation bracket and the cover plate. An opening is provided on the inner bottom surface or side surface of the DC wire channel, and the MC4 DC connector and the positive and negative PV DC cables pass through the opening and enter the DC wire channel.

[0008] As a preferred technical solution of the utility model, the profile support is in a π shape, and both sides of the profile support are installed on the roof structure purlins through bolts.

[0009] As a preferred technical solution of the utility model, the installation bracket is in a Y shape, and the inner bottom surface of the installation bracket is fixedly connected to the top of the profile support through self-tapping screws.

[0010] As a preferred technical solution of the present utility model, the serrated reinforcing surface is hermetically connected to the frame of the flat photovoltaic tile through structural silicone, and the frames of two adjacent flat photovoltaic tiles are hermetically connected through structural silicone.

[0011] As a preferred technical solution of the present utility model, both ends of the bottom surface of the cover plate are integrally connected with concave grooves, the bottom of the inner wall of the concave groove is integrally connected with arc-shaped convex blocks, the top of the inner walls of both sides of the mounting bracket is integrally connected with arc-shaped convex blocks, and the top ends of the two vertical extension edges of the mounting bracket are clamped inside the concave grooves through the arc-shaped convex blocks.

[0012] As a preferred technical solution of the present utility model, the opening diameter of the DC wire channel is 20-25 mm, and the diameter of the PV DC cable at the positive and negative poles of the MC4 DC connector is 15-19 mm.

[0013] The beneficial effects of the present utility model are as follows:

[0014] First, in this kind of side-outlet building photovoltaic integration profile system, through the cooperation between the cover plate and the mounting bracket, a sealed DC wire channel is formed, and the MC4 DC connector is fixed inside the aluminum profile to prevent the MC4 DC connector from being exposed to rain and soaked in water.

[0023] The following is a description of the preferred embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model and are not used to limit the present utility model.

[0024] Embodiment 1: As Figures 1 - 3 shown, a side - outlet building photovoltaic integrated profile system includes an installation bracket 1. The bottom surface of the installation bracket 1 is fixedly connected to a profile support 2. Serrated strengthening surfaces 3 are provided on both extended sides of the bottom surface and the outer side of the vertical extended side of the installation bracket 1.

[0025] A cover plate 5 is snap - fitted on the top surface of the installation bracket 1, and a DC line channel for the wiring groove and the wire - routing channel of the PV DC cable and the MC4 DC connector is formed between the installation bracket 1 and the cover plate 5. An opening is provided on the inner bottom surface or side surface of the DC line channel, and the MC4 DC connector and the PV DC cables of the positive and negative poles pass through the opening into the DC line channel. The diameter of the opening of the DC line channel is 20 - 25 mm, and the diameter of the PV DC cables of the positive and negative poles of the MC4 DC connector is 15 - 19 mm.

[0026] Both ends of the bottom surface of the cover plate 5 are integrally connected with concave grooves. The bottom of the inner wall of the concave groove is integrally connected with arc - shaped convex blocks. The top of the inner walls of both sides of the installation bracket 1 is integrally connected with arc - shaped convex blocks. The top ends of the two vertical extended sides of the installation bracket 1 are snap - fitted inside the concave grooves through the arc - shaped convex blocks.

[0027] Through the cooperation between the cover plate 5 and the installation bracket 1, a sealed DC line channel is formed, fixing the MC4 DC connector inside the aluminum profile to prevent the MC4 DC connector from being exposed to rain and soaked in water.

[0028] The profile support 2 is in a π shape. Both sides of the profile support 2 are installed on the roof structure purlin through bolts. The installation bracket 1 is in a Y shape. The inner bottom surface of the installation bracket 1 is fixedly connected to the top of the profile support 2 through self - tapping screws.

[0029] By connecting the profile support 1 to the roof structure purlin, the photovoltaic module is elevated, thus forming a new roof on the old roof and realizing the integration of photovoltaic architecture.

[0030] The serrated strengthening surface 3 is hermetically connected to the frame of the flat photovoltaic tile through structural silicone. The frames of two adjacent flat photovoltaic tiles are hermetically connected through structural silicone. Serrated strengthening surfaces 3 are designed on both the extended sides of the two sides of the industry-shaped mounting bracket 1 and on the outer side of the vertical extended side to strengthen the bonding surface of the silicone and further improve the bonding effect of the silicone.

[0031] Embodiment 2: The difference from Embodiment 1 is that the side nailing fixing mode is used to replace the structural silicone to fix the frame of the flat photovoltaic tile. As Figures 4 - 5 shown, there are two raised groove lines 4 on the inner sides of the vertical extended sides of both sides of the mounting bracket 1. The raised groove lines 4 can play the role of self-tapping limit for screws in the side nailing fixing mode.

[0032] In the installation scenario where the carport is often affected by strong wind environment, the structural silicone fixing method can no longer provide stable fixation for the flat photovoltaic tile. Therefore, the side nailing fixing mode can be adopted. The industry-shaped mounting bracket 1 can be obliquely nailed from the inner side, piercing through the frame of the flat photovoltaic tile obliquely to achieve mechanical fixation between components, and at the same time, the fixing nails are hidden, which is beautiful and firm.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
