[0025] Example 1

[0026] like Figure 1-3 As shown, a photovoltaic carport drainage system includes a carport, a mounting frame 1 is provided on the top of the carport, the side of the mounting frame is in a "V" shape, and a plurality of photovoltaic panels 2 are laid on the mounting frame 1. The mounting frame 1 includes a plurality of groups of inclined beams 11 arranged in a "V" shape, and a plurality of purlins 12 are arranged in parallel between two adjacent groups of inclined beams. The utility model adopts "C"-shaped channel steel. A plurality of first drainage trough mounting frames are arranged between the two purlins near the lowest point of the "V". A first drainage trough 3 is installed on the first drainage trough frame. The cross-section of the first drainage trough 3 is "U"-shaped, and a plurality of downspouts 31 are provided at the bottom of the first drainage trough. The distance between two adjacent downspouts is 1.5-2.5m (2m is selected in this embodiment), and a downspout is installed on each downspout. The material of the first drainage trough 3 in this embodiment is galvanized aluminum-magnesium material with a thickness of 1mm. A plurality of second drainage grooves 4 arranged in parallel are installed on the purlin 12 along the oblique side of the "V" shape, and the second drainage grooves 4 are parallel to the inclined beams 11. The second drainage trough is located below the edges of two adjacent photovoltaic panels. The second drainage trough is used to guide rainwater into the first drainage trough. The cross-section of the second drainage trough is "M" shaped.

[0027] Several downspouts are set at the bottom of the first drainage trough 3, and the distance between two adjacent downspouts is selected to be 2m. A downspout is installed on each downspout 31. It avoids excessive water inflow into the middle due to water on both sides, and solves the problem of excessive water flow. Rainwater is drained to the groundwater well through the downspout, and there is no need to discharge it into the edge of the bracket, which can avoid the problem of large amounts of water accumulation on the road. The first drainage trough is set at the lowest point in the middle of the "V"-shaped mounting frame. Based on the symmetry, the design here is also difficult to find that there is a drainage system, and it looks more beautiful from the side compared to the traditional design. The gap between the photovoltaic panels along the oblique beam direction adopts a second drainage trough with an "M"-shaped cross-section. The water from the photovoltaic panels on both sides flows into the second drainage trough, and then flows into the first drainage trough. The cross-section of the first drainage trough is "U"-shaped, so that it can accommodate more water flow.

[0028] Specifically, a support rod 13 is provided on the purlin 12, and the support rod 13 is arranged parallel to the inclined beam. The support rod 13 is used to support the photovoltaic panel 2, and the photovoltaic panel 2 is fixed to the support rod 13 with bolts or screws. The support rod 13 is located in the middle position of each photovoltaic panel 2.

[0029] Several fixing components are mounted on the second drain trough 4, which are used to secure the edges of the photovoltaic panels. These components include a lower fixing member 51 and an upper fixing member 52, which work together to secure the edges of the photovoltaic panels. The middle portion of the upper fixing member 52 is bolted to the middle portion of the lower fixing member 51. The lower fixing member has two bends 511 at each end, which secure to the sides of the second drain trough. The second drain trough has an "M"-shaped cross-section, which facilitates the installation of the lower fixing member 51.

[0030] The first drain chute mounting frame includes two vertical supports 61, a crosspiece 62, and a stopper 63. The two vertical supports 61 are mounted on the two purlins 12 near the lowest point of the "V" shape. The crosspiece 62 is installed between the two vertical supports 61 and supports the first drain chute. The stopper 63 is installed on the crosspiece 62 to position the first drain chute 3 on the crosspiece 62.

[0031] A sealing strip is installed on the gap between two adjacent photovoltaic panels 2 in a direction parallel to the purlin 12 .

[0032] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
