The invention relates to an intelligent pirate expelling safety system. The intelligent pirate expelling safety system comprises a plurality of bases arranged along the side of a ship, supporting rodshinged to the bases through hinges, wherein the outer ends of the supporting rods can extend out of a board after rotating transversely, first springs are arranged on the lower parts of the supporting rods, and the first springs are positioned outside or inside the bases; signal triggers are arranged on the upper parts, located on the inner side portions of the bases, of the supporting rods, andcorresponding limiting stoppers are fixedly arranged above the signal triggers; groove-shaped medicine boxes parallel to the side of the ship are fixedly arranged at the outer ends of the supporting rods, bearings are connected to the two ends of the groove-shaped medicine boxes correspondingly, and the groove-shaped medicine boxes can rotate around the bearings; guide posts are arranged at both ends of the bottom surfaces of the groove-shaped medicine boxes, second springs are arranged outside the guide posts in a sleeving mode, and barbed press plates are connected to the upper ends of the second springs; and medicine containers are placed in the groove-shaped medicine boxes and maintain set gaps with thorns of the barbed pressing plates. The an intelligent pirate expelling safety systemfurther has the functions of preventing external personnel from boarding, alarming and expelling, the three functions are combined with each other, and the design is ingenious.
