The invention discloses an intelligent sampling device for typical flammable and explosive dangerous chemical liquid. The intelligent sampling device comprises a sampling device and a shunting device, wherein the sampling device adopts a two-degree-of-freedom mechanical arm, an actuator of the sampling device is a rotatable turntable controlled by a steering engine, and a plurality of sampling heads are mounted on the turntable. The sampling heads are respectively connected with a plurality of peristaltic pumps mounted in the shunting device through pump pipes, and the output ends of the sampling heads are connected with a plurality of liquid storage injectors. Liquid sucked by the sampling heads is pumped into the liquid storage syringes through the pump pipes and the peristaltic pumps, when the liquid sampled by the sampling heads enters the corresponding liquid storage syringes, the piston pull rods are pushed to gradually move backwards through pressure generated by flowing-in liquid until the piston pull
