A thermal protection device suitable for an initiating explosive device unlocking bolt comprises a hanging seat thermal protection structure, an unlocking bolt thermal protection structure and a cable thermal protection structure. The hanging seat heat protection structure comprises a heat protection layer, a heat insulation layer, a protection layer, a hook face hasp, a suede face hasp and a buckle loop, and heat protection is carried out on a brake parachute hanging belt connected with the hanging seat and part of an unlocking bolt. The unlocking bolt is wrapped by a plurality of layers of high-temperature heat insulation belts and aramid fiber silk in a winding manner, and is fixed by a polyimide adhesive tape in a winding manner; the cable is wrapped by a high-temperature heat insulation belt and is wound and fixed by a polyimide adhesive tape. According to the thermal protection device, thermal protection of the initiating explosive device unlocking bolt is achieved through the hanging seat thermal protection structure, the unlocking bolt thermal protection structure and the cable thermal protection structure, and the initiating explosive device unlocking bolt can work smoothly.
