System for sampling molten metal medium in reactor vessel

The invention relates to a sampling system for a molten metal medium in a reactor vessel, the sampling system comprises a sampling pipeline with two open ends, a metal cable, a winding drum, a driving part and a sampling vessel, one end of the sampling pipeline is used for extending below the liquid level of the molten metal medium in the reactor vessel, and at least part of the metal cable is movably arranged in the sampling pipeline in a penetrating manner; the winding drum and the driving part are arranged outside the sampling pipeline, one end of the metal cable is wound on the winding drum, the driving part is connected with the winding drum and used for driving the winding drum to rotate so as to wind or release the metal cable, and the sampling container is connected to the other end of the metal cable. According to the sampling system for the molten metal medium in the reactor container, the metal cable is arranged to drive the sampling container connected with the metal cable to penetrate through the
