Anti-fracture multipoint sheathed thermocouple device and temperature measurement structure

The invention belongs to the technical field of thermocouples, particularly relates to an anti-fracture multipoint sheathed thermocouple device, and aims to overcome the defect that the lower end of a sleeve is easy to fracture when the bunker position is high in the conventional thermocouple device in a large-capacity coal silo. The sleeve penetrates through the mounting seat; the junction box mounting assembly is arranged at the upper end of the sleeve; the explosion-proof junction box is mounted on the junction box mounting assembly; a plurality of flexible armored thermocouples; the elastic piece abuts against the lower portion of the mounting base and is arranged outside the sleeve in a sleeving mode; wherein the lower end of the casing pipe floats in the air so as to swing, and when the casing pipe is subjected to force from materials, the elastic piece is compressed, and the mounting seat and the casing pipe descend. The multi-point sheathed thermocouple device has the beneficial effect that the breaka
