[0028] In a specific embodiment of the utility model, the shell 1 is used to be fixed on the shell of the heating furnace, and the straight rod 3 is used to connect the insulation board 4. The insulation board 4 is made of asbestos board material, which is made of raw materials such as asbestos, glass fiber, and clay. It has good tension and pressure resistance and can withstand a high temperature of about 1400°C. At the same time, it has the effects of heat insulation and sound insulation to protect the equipment in the shell 1 and prevent the structure in the shell 1 from being damaged by high temperature when the heating furnace is in use. The device is used when the heating furnace stops working. The straight rod 3 is controlled to move by the extended end of the electric push rod 2. The straight rod 3 drives the insulation board 4, the protective shell 6, and the positioning sleeve 9 to move outward, so that the protective shell 6 enters the interior of the heating furnace, and the inner wall of the heating furnace is detected by the industrial probe 7. Then, the extended end of the small motor 10 is controlled to drive the second gear 11 to rotate, and the first gear 8 is driven to rotate under the action of meshing.
