Further, a clamping groove 2121 is formed in the second mounting platform 212 of the second support beam 2, a protrusion is formed at the bottom of the second adhesive tape 43, and the protrusion at the bottom of the second adhesive tape 43 is clamped into the clamping groove 2121, so that the second adhesive tape 43 is connected with the second mounting platform 212 in a positioning manner, the second adhesive tape 43 can be assembled between the second support beam 2 and the photovoltaic module unit 3 more firmly, and the sealing and waterproof performance can be improved.

In the above embodiment, the second upper support portion 21 and the second lower support portion 22 in the second support beam 2 are integrally formed, but the utility model is not limited thereto, and the second upper support portion 21 and the second lower support portion 22 may be assembled separately, and since the structure of the second upper support portion 21 and the second lower support portion 22 is relatively simple and the assembly is also convenient, the specific formation of the second support beam 2 is not specifically limited, which can be understood and accepted by those skilled in the art, and therefore, the related mechanisms will not be described again;

in the above embodiment, the shape of the mounting groove 1131 may be different shapes such as a circle, an ellipse, a diamond, and the like, and the utility model is not limited thereto, and the shape of the first support beam 1 is more reasonable in a circular shape in consideration of the manufacturing process of the section.

The above embodiments are merely illustrative of the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
