The invention discloses a thermal protection device which comprises an upper panel, a bottom panel, an upper corrugated plate layer and a lower corrugated plate layer, wherein the upper corrugated plate layer comprises a plurality of upper corrugated plates which are arranged in sequence; the lower corrugated plate layer comprises a plurality of lower corrugated plates which are arranged in sequence; the upper corrugated plate layer is arranged above the lower corrugated plate layer; the upper and lower corrugated plate layers are arranged in a staggered manner; the lower ends of the at the upper part corrugated plates and the upper ends of the lower corrugated plates are connected with one another through a heat insulation and bearing bolt connection structure; the heat insulation and bearing bolt connection structure comprises joint bolts, upper heat insulation gaskets, middle heat insulation spacers, lower heat insulation gaskets, and connecting nuts; the gap between the upper panel and the lower ends of the upper corrugated plates is filled with a high-temperature resistant insulating material; the gap between the bottom panel and the upper ends of the lower corrugated plates is filled with a middle-temperature resistant insulating material. Due to the adoption of the thermal protection device provided by the invention, the problems of thermal short-circuiting of the connection structure and thermal mismatch of a cold-hot structure of the thermal protection device can be solved.
