[0032] Two adjacent connecting portions 11 are located at one end surface of the purlin 1; the two connecting portions 11 are respectively connected to the first end of the protruding portion 12 from both sides, and the protruding portion 12 extends in a direction perpendicular to the end surface of the purlin 1;

[0033] The protruding portion 12 is provided with a recessed mounting groove 121, and the mounting groove 121 is located at the second end of the protruding portion 12 away from the connecting portion 11;

[0034] The two connecting portions 11 are respectively used to connect two photovoltaic modules 2 ; the mounting groove 121 is used to match and abut against the outer peripheral surface of the main beam 3 .

[0035] like Figure 1-2 As shown, the mounting groove 121 located at the second end of the protrusion 12 can be fixed to the outer peripheral surface of the main beam 3, and then the sides of the two photovoltaic components 2 can be fixed by the two connecting parts 11 located on both sides of the protrusion 12. In this way, multiple photovoltaic components 2 can be fixed on the same side of the main beam 3 in turn.

[0036] The main beam 3 is fixed by using the mounting groove 121 that matches the shape and size of the outer peripheral surface of the main beam 3 , so that the installation stability of the main beam 3 can be improved.
