AI Technical Summary
In the photovoltaic tracking bracket system, the deformation and failure of the purlin mainly occurs in the bolt position fixed to the spindle, resulting in insufficient strength, and the overall increase in the wall thickness of the purlin will increase the cost.
A purlin reinforcement structure for photovoltaic tracking bracket is designed. By setting reinforcement parts at the bottom of the purlin and fixing them through the rivet port, the reinforcement parts are attached to the purlin, and the two sides are extended outwards through bending points to abut against the inner side of the purlin, forming a U-shaped or W-shaped reinforcement structure. The fixing parts include bolts and fixing plates, and fixed with the fixing tubes through the fixing plates.
With the same wall thickness and depth, the strength of the new purlin reinforced structure can be enhanced by more than 40%, and through the rivet-free riveting method, the addition of additional parts and holes are avoided, and the riveting speed and efficiency are improved.
