Incinerator thermocouple

The invention relates to a thermocouple. The invention relates to an incinerator thermocouple. The device comprises a lifting device and a positioning device arranged at the bottom of the lifting device, the lifting device comprises a detection mechanism, the detection mechanism comprises a thermocouple rod, and a lifting mechanism is arranged outside the thermocouple rod. When the positioning cylinder is installed on the incinerator, air in the inflation groove enters the circulation groove through the conduction groove, the bottom end of the thermocouple rod extends into the incinerator, the sensing effect of the thermocouple rod on the temperature change in the incinerator is greatly improved, and the thermocouple rod is adjusted according to the temperature in the incinerator, so that the temperature change in the incinerator can be accurately detected. And after the incineration of the incinerator is finished, the middle position of the thermocouple rod is retracted into the positioning cylinder, so that
