[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Both ends of the inner side of the side frame 2 are fixedly connected with sealing plates 4. Through the setting of the sealing plates 4, the ends of the lower frame 1 and the upper frame 3 are sealed with the side frame 2 through the sealing plates 4, thereby reducing the probability of water seepage at the joints of the frames and improving the waterproof performance of the aluminum alloy frame.

[0021] The lower frame 1, the side frame 2 and the upper frame 3 all include a frame body 5. One end of the frame body 5 is provided with a mounting groove 6 adapted to the solar photovoltaic panel. The inner wall of the mounting groove 6 is fixedly connected with a sealing gasket. The sealing gasket material can be rubber to increase the sealing between the aluminum frame and the solar photovoltaic panel. The other end of the frame body 5 is fixed with a mounting plate 7. Through the setting of the mounting plate 7, the mounting plate 7 can be used to fix the lower frame 1, the two side frames 2 and the upper frame 3 together, and the fixed part is located on the back of the solar aluminum frame, which can prevent rainwater from seeping into the mounting groove 6 through the fixed part, thereby further improving the waterproof performance of the solar aluminum frame.

[0022] Please continue reading Figures 1 to 5 A water barrier strip 10 is fixedly connected to the outer side of the upper frame 3. There is a gap between the water barrier strip 10 and the upper frame 3. The size of the gap can be set according to needs and is not limited here. The bottom of the water barrier strip 10 is located below the bottom of the upper frame 3. Through the setting of the water barrier strip 10, the water barrier strip 10 can guide rainwater to prevent rainwater from contacting the mounting groove 6 of the upper frame 3, thereby solving the problem of water seepage in the mounting groove 6 of the upper frame 3 from the source.

[0023] Specifically, the outer wall of the mounting groove 6 on the lower frame 1 is a hollow structure, and a water guide plate 9 is fixed on the top of the inner cavity of the outer wall of the mounting groove 6. The water guide plate 9 includes a seepage plate 12. Through the setting of the seepage plate 12, rainwater intercepted by the outer wall of the mounting groove 6 can penetrate into the inner cavity of the outer wall of the mounting groove 6 to avoid water accumulation. The material of the seepage plate 12 can be an aluminum alloy profile with micropores evenly opened. The size of the micropores can be set according to needs and is not limited here.
