As a further improvement, the ends of the inner layer top and the outer layer top are bent inwards to form a certain angle beta, and the size of the angle beta is determined according to the inclination angle of the photovoltaic panel.

As a further improvement, the number of the flow guide holes is 3-5 in each part.

Has the advantages that:

the fluid director has the characteristics of simple operation, good fluid directing effect and low possibility of blockage after long-time use. At first set up the cavity structure, the flow of the sewage of being convenient for and slow down the jam, cavity inner wall coating teflon coating simultaneously prevents that silt etc. from adhering to the inner wall, and outer lateral wall slope design can flow with higher speed dust, sewage etc. when rivers are less, the baffle design can be with the water conservancy diversion hole of sewage direct direction lateral wall, and direct discharge reduces the risk of lateral wall dust adhesion, and when rivers are great, the water conservancy diversion hole of bottom then can further assist the emission of sewage.
