Abstract

The present disclosure relates to the technical field of security detection device, and in particular to a lead curtain protective device for a detecting device and a ray shielding method. The lead curtain protective device comprises: at least two lead curtains; a supporting assembly comprising a working area and a standby area; a first transmission assembly adapted to drive the lead curtains to move in a conveying channel; and a second transmission assembly adapted to transfer the lead curtains between the standby area and the working area, wherein the second transmission assembly is adapted to transfer the lead curtains from the standby area to the working area, so that the lead curtains fall into a starting point of the conveying channel and are located behind an article to be detected; the first transmission assembly is adapted to drive the lead curtains to synchronously move with the article to be detected in front and drive the lead curtains to move from the starting point of the working area to a starting point of the standby area; and the second transmission assembly is further adapted to drive the lead curtains to enter the standby area and move in the standby area.
