Solar photo-thermal evaporation steam collecting device

The invention relates to the field of seawater desalination, in particular to a solar photo-thermal evaporation steam collecting device which comprises a transparent top cover and a collecting device which is connected with the transparent top cover in a sealed mode and internally provided with an interface evaporation unit. A heat insulation plate on which a plurality of fiber cloths are stacked is mounted at the opening of the water storage tank, the two sides of the fiber cloths droop into seawater, and the parts, located on the heat insulation plate, of the fiber cloths are loaded with photo-thermal materials; the side wall of the collecting device is provided with a plurality of airflow disturbers capable of blowing steam generated by seawater heating and evaporation inwards to the side wall of the collecting device for condensation collection or extracting the steam outwards for collection, and each airflow disturber comprises a motor which is connected with a shell and is provided with a plurality of f
