Protection structure of electric power protection box

The utility model relates to the technical field of electric power protection boxes, in particular to an electric power protection box protection structure, which comprises an electric power box, a box cover and a protection box, a heat dissipation cylinder is inserted in the upper end of the electric power box in a penetrating manner, a heat dissipation fan is arranged in the heat dissipation cylinder, the box cover is arranged above the electric power box, and a filter screen is arranged between the box cover and the electric power box. The beneficial effects of the power box are that the heat dissipation fan is used to dissipate heat of the power box, the heat is discharged upwards through the heat dissipation cylinder and then is discharged through the filter screen, and when snow falls in winter and the heat generated in the power box is discharged upwards, the heat heats the box cover, so that the snow is melted quickly, and the power box is convenient to use. Therefore, snow accumulation is prevented f
