Description

[0036] Embodiment 1:
[0037] Refer to Figures 1 to 7, in an embodiment of the present utility model, a novel photovoltaic module frame device includes: a photovoltaic module frame body 1 and a backplane connecting member connected to each other. At least one connecting groove 9 is evenly opened on both sides of the backplane connecting member 2. Of course, according to actual situations, a plurality of connecting grooves 9 are evenly opened on both sides of the backplane connecting member 2. The connecting groove 9 is adapted to a connecting head 8 installed on one side of the photovoltaic module frame body 1. The cross-sectional shape of the connecting head 8 is one of a circular arc, a square, a rectangle, a triangle, a rhombus, and an ellipse. A water collecting groove 13 is opened at the top of the backplane connecting member 2, and a drain hole 14 is opened at the bottom of the water collecting groove 13, and the drain hole 14 leads to the bottom of the backplane connecting member 2;
[0038] During use, a backplane connecting member is installed on the side of the photovoltaic module frame body 1 (as shown in Figure 1 ), the connecting head 8 is aligned with the connecting groove 9 and inserted, so that the photovoltaic module frame body 1 and the backplane connecting member 2 are plugged together, and the side surfaces of the photovoltaic module frame body 1 and the backplane connecting member are attached, so that the photovoltaic module frame body 1 and the backplane connecting member 2 are connected into a whole, thereby further improving the front compressive capacity of the photovoltaic module frame body 1; Use one backplane connecting member 2 to connect two photovoltaic module frame bodies 1 at the same time (as shown in Figure 5 ), the two photovoltaic module frame bodies 1 are formed into a whole, thereby improving the overall structural strength during photovoltaic installation. Moreover, the water collecting groove 13 can concentrate the precipitation, and the concentrated precipitation is discharged from the bottom of the backplane connecting member 2 through the drain hole 14, which is beneficial to drainage.
[0039] By setting the photovoltaic module frame body 1 and the backplane connecting member 2 connected by a plugging method, the structural strength of the photovoltaic module frame body 1 is further improved. By opening connecting grooves 9 on both sides of the backplane connecting member 2, the installation method of the photovoltaic module frame body 1 is more diversified, and the overall structural strength of the photovoltaic module frame body 1 during combined installation is improved. The water collecting groove 13 and the drain hole 14 are provided, which is beneficial to the concentrated discharge of precipitation.
[0040] Embodiment 2:

[0053] Embodiment 6:
[0054] As Figures 2-3 shown in the figure, an extension plate 6 is installed on one side of the photovoltaic module frame body 1, and a reinforcing plate 7 is inclinedly installed between the extension plate 6 and the photovoltaic module frame body 1. During use, the extension plate 6 can increase the bottom support area of the photovoltaic module frame body 1, making the photovoltaic module frame body 1 more stable. The reinforcing plate 7 connects the extension plate 6 and the photovoltaic module frame body 1 to form a triangular frame structure, and the overall structure is more stable and has stronger anti-deformation ability.
[0055] By setting the extension plate 6 and the reinforcing plate 7, a triangular frame structure is formed among the reinforcing plate 7, the extension plate 6, and the photovoltaic module frame body 1, and the overall structure is more stable and has stronger anti-deformation ability.
[0056] Working principle: During use, a backplane connector is installed on the side of the photovoltaic module frame body 1 (as Figure 1 shown in the figure). Align the connector 8 and insert it into the connection slot 9, so that the photovoltaic module frame body 1 is inserted and connected with the backplane connector 2. The side of the photovoltaic module frame body 1 is in close contact with the backplane connector, connecting the photovoltaic module frame body 1 and the backplane connector 2 into a whole, thereby further improving the front compressive capacity of the photovoltaic module frame body 1. Use one backplane connector 2 to connect two photovoltaic module frame bodies 1 at the same time (as Figure 5As shown, the two photovoltaic module frame bodies 1 are formed into a whole, thereby improving the overall structural strength during photovoltaic installation. Moreover, the water collecting trough 13 can concentrate the precipitation, and discharge the concentrated precipitation from the bottom of the backplane connecting member 2 through the drain holes 14, which is beneficial to discharging the precipitation, prolonging the service life, and increasing the stability of the power generation power.
