The setting of the fixing component 19 facilitates the arrangement and fixing of the photovoltaic cables. When there is water leakage in the inner cavity of the wire trough body 1, the water can be easily discharged through the setting of the drainage groove 21, and the inclined block 2 0 is convenient for gathering water above the drainage groove 21, so as to facilitate timely discharge.
