[0052] With the setting of the bending part 31, the position of the photovoltaic module 2 can be limited, so that the photovoltaic module 2 is aligned when it is attached to the side wall of the bending part 31, thereby facilitating the limitation of the position and attitude of the photovoltaic module 2, avoiding the phenomenon of horizontal deviation of the photovoltaic module 2 after installation, and ensuring the stability of the overall structure; at the same time, the second sealing gasket layer 6 and the first sealing gasket layer 5 are used to form a sealing layer structure completely covering the end of the photovoltaic module 2, so that the sealing effect is better, and after long-term use, a relative sealing structure can still be formed in the state that the bending part 31 is attached to the middle connecting piece 1, which can avoid the infiltration of rainwater, thereby playing a good protection role on the internal structure, prolonging the service life of the photovoltaic module fixing structure for the integration of photovoltaic modules and profiled steel sheet roof, and reducing the subsequent maintenance cost.

[0053] In addition, through the setting of the flow guide groove 32 and the drainage groove 311, the rainwater temporarily stored on the surface of the photovoltaic module 2 can be shunted and guided, so that the rainwater is dispersed into the drainage groove 311 and discharged, thereby accelerating the dispersion speed of the rainwater on the surface of the photovoltaic module 2, so that the rainwater on the surface of the photovoltaic module 2 can be removed faster by evaporation, avoiding the accumulation of too much rainwater on the surface of the photovoltaic module 2 causing penetration, and on the other hand, reducing the probability of penetration of rainwater into the workpiece, thereby playing a good protection effect.
