Description

Technical Field

[0001] The utility model belongs to the field of photovoltaic energy, and specifically relates to a photovoltaic building integrated device. Background Art

[0002] When photovoltaic panels are installed on the roof, they are divided into BIPV and BAPV according to the installation method. BAPV is to install a photovoltaic array on the original color steel tile roof of the factory building. In essence, it still uses color steel tiles as the roof, but the service life of color steel tiles is short and they are prone to leakage. The BIPV method directly uses the photovoltaic panel array as a complete roof to play a role in waterproofing and rainproofing. BIPV can be designed directly in the early stage of construction. The advantage is that it is beautiful and complete, and the disadvantage is high cost. It can also be installed later. The factory building after installation no longer relies on the color steel tile roof for waterproofing. Therefore, even if the old color steel tile roof is aging and leaking, it does not need to be renovated.

[0003] In the prior art, when BIPV is installed later, the drainage method is to make the keel into a drainage trough, which is distributed under the gaps of the photovoltaic panels. When it rains, rainwater is collected and discharged through the keel. The rainwater falls into the keel from the gaps of the photovoltaic panels nearby and then is collected and discharged. However, the drainage capacity of the keel drainage trough is limited. When the rainfall is too heavy and exceeds the drainage capacity of the keel, the keel water is easy to overflow to both ends. Utility Model Content

[0004] The purpose of the utility model is to provide a photovoltaic building integrated device in order to solve the above problems.

[0005] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0006] A photovoltaic building integrated device, comprising a photovoltaic panel, and a keel with a drainage groove and a slope along the drainage direction, wherein the photovoltaic panel is pressed on the keel by a first pressing block and a second pressing block, a water guide eave is arranged at a lower end of the photovoltaic panel, and a connecting eave is movably arranged below the water guide eave, and the connecting eave is used to guide water from the water guide eave to the photovoltaic panel below;

[0007] Among them, connecting rods are hinged at both ends of the connecting eaves, and cross bars are arranged at the ends of the connecting rods. Side sliding grooves for sliding the cross bars are arranged on the sides of the frame of the photovoltaic panel. The second pressing block has a beveled edge, which is used to drive the cross bars to press the connecting eaves while the second pressing block presses the photovoltaic panel.

[0008] As a further optimization solution of the present invention, the cross-section of the keel is W-shaped, the keel is set in a W-shape, has the function of a drainage groove, and the middle protrusion can cooperate with the pressure block.

[0009] As a further optimization scheme of the utility model, a screw hole seat is provided in the middle part of the keel, and the first pressing block and the second pressing block are fixed to the screw hole seat by bolts. The screw hole seat is used to install the pressing block, and the first pressing block and the second pressing block press the frame of the photovoltaic panel onto the keel by bolts and the screw hole seat.

[0010] As a further optimization scheme of the utility model, the surface of the keel is provided with a pad for raising the lower end of the photovoltaic panel, so as to make the upper photovoltaic panel higher than the lower photovoltaic panel, so as to form a height difference and facilitate the connection between the upper and lower eaves.

[0011] The beneficial effects of the utility model are:

[0012] The utility model connects the gap between two photovoltaic panels through the water guide eaves and the connecting eaves in the slope direction, so that rainwater can flow directly downward through the drop, without the need to set a gutter for the horizontal gap. Part of the rainwater flows directly downward along the surface of the photovoltaic panel, reducing the drainage pressure of the keel. In addition, the fixing method of the connecting eaves in this solution does not affect the disassembly and assembly of a single photovoltaic panel. One side of the connecting eaves is stretched tightly against the edge of the upper photovoltaic panel, and the other side naturally hangs down and presses on the lower photovoltaic panel without a gap, forming a tile-like effect, which is not easy to leak even if rain splashes.

[0020] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Example 1

[0022] like Figure 1-6 As shown, a photovoltaic building integrated device includes a photovoltaic panel 2, and also includes a keel 1 with a drainage groove and a slope along the drainage direction. The photovoltaic panel 2 is pressed on the keel 1 by a first pressing block 3 and a second pressing block 4. A water guide eave 21 is provided at the lower end of the photovoltaic panel 2, and a connecting eave 51 is movably provided below the water guide eave 21. The connecting eave 51 is used to guide the water of the water guide eave 21 into the photovoltaic panel 2 below;

[0023] Among them, connecting rods 53 are hinged at both ends of the connecting eaves 51, and cross bars 52 are arranged at the ends of the connecting rods 53. Side sliding grooves 22 for sliding the cross bars 52 are arranged on the side edges of the frame of the photovoltaic panel 2. The second pressing block 4 has a beveled edge 41, which is used to drive the cross bars 52 to press the connecting eaves 51 while the second pressing block 4 presses the photovoltaic panel 2.

[0024] In this solution, by connecting the gap between the two photovoltaic panels 2 through the water-guiding eaves 21 and the connecting eaves 51 in the slope direction, rainwater can flow directly downward through the drop without setting a gutter for the horizontal gap. Part of the rainwater flows directly downward along the surface of the photovoltaic panel 2, reducing the drainage pressure of the keel 1. In this solution, the fixing method of the connecting eaves 51 does not affect the disassembly and assembly of a single photovoltaic panel 2. One side of the connecting eaves 51 is pulled tightly against the edge of the upper photovoltaic panel 2, and the other side naturally hangs down and presses on the lower photovoltaic panel 2 without a gap, forming a tile-like effect, which is not easy to leak even if rainwater splashes.

[0025] It should be noted that if a tile-type installation is directly adopted to press the upper photovoltaic panel 2 onto the edge of the lower photovoltaic panel 2, it is not easy to disassemble and assemble them individually after they are installed and pressed.

[0026] Furthermore, the cross section of the keel 1 is W-shaped, having the function of a drainage groove, and the protrusion in the middle can cooperate with the pressing block.

[0027] A screw hole seat is provided in the middle part of the keel 1, and the first pressing block 3 and the second pressing block 4 are fixed to the screw hole seat by bolts 42. The screw hole seat is used to install the pressing blocks. The first pressing block 3 and the second pressing block 4 press the frame of the photovoltaic panel 2 onto the keel 1 by bolts 42 and the screw hole seat.

[0028] The surface of the keel 1 is provided with a pad 11 for raising the lower end of the photovoltaic panel 2, so as to make the upper photovoltaic panel 2 higher than the lower photovoltaic panel 2, so as to form a height difference and facilitate the connection of the eaves 51 to connect the upper and lower parts.

[0029] The specific implementation method is as follows: when it is necessary to disassemble and assemble a single photovoltaic panel 2, first remove the first pressing block 3 and the second pressing block 4 related to the photovoltaic panel 2, and slide the photovoltaic panel 2 slightly downward to take it out. The connecting eaves 51 of the photovoltaic panel 2 itself and the connecting eaves 51 of the upper photovoltaic panel 2 will not restrict the removal. When installing again, insert the photovoltaic panel 2 under the upper connecting eaves 51, tighten the first pressing block 3 and the second pressing block 4, wherein the second pressing block 4, when tightened, pushes the cross bar 52 to slide through the bevel 41, and then tightens the connecting eaves 51 through the connecting rod 53 to eliminate the gap and prevent splashing raindrops from entering through the gap.

[0030] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
