TECHNICAL FIELD

[0002] In industrial production, accurate measurement of furnace temperature is crucial for process control and optimization. Furnace temperature measurement usually uses temperature sensors, among which thermocouples are a common choice. Thermocouples measure temperature by utilizing the thermoelectric potential generated by two different metal materials when temperature changes. It has the advantages of fast response speed, wide measurement range, and high precision. A thermocouple is usually composed of a measuring end, connecting wires, and a display instrument. The measuring end directly contacts the high-temperature environment inside the furnace and converts the temperature signal into a thermoelectric potential signal. The connecting wires transmit the thermoelectric potential signal to the display instrument, which processes and displays the signal to obtain the temperature value of the furnace.

[0003] In actual furnace temperature measurement scenarios, the existing temperature sensors have some deficiencies in use. In the furnace, due to the influence of gravity and falling coke, the thermocouple is prone to bending deformation. For example, in some industrial furnaces, the thermocouple is in a high-temperature environment for a long time and is subjected to the action of gravity, which easily bends downward. In addition, the falling coke in the furnace also produces impact force on the thermocouple, causing the thermocouple to bend. This bending deformation affects the measurement accuracy and reliability of the thermocouple, and even causes the thermocouple to be damaged and unable to work normally. Therefore, the technical field proposes a temperature sensor anti-bending mechanism to solve the above problems. SUMMARY

[0004] To make up for the above shortcomings, the utility model provides a temperature sensor anti-bending mechanism, aiming to improve the problem that the thermocouple in the prior art is easily affected by external factors during long-term use and is bent and damaged.

[0006] The anti-bending assembly comprises a servo motor and a cylindrical gear two, the servo motor is located on one side of the outside of the thermocouple, the cylindrical gear two is sleeved on the outer periphery of the thermocouple, the output end of the servo motor is fixedly connected with a cylindrical gear one, and the outer periphery of the cylindrical gear one and the cylindrical gear two is sleeved with a chain.

[0007] Further, the inner side of the flange bearing is rotationally connected with the outer side of the thermocouple, and one end of the wire is electrically connected with the internal circuit input end of the thermocouple.

[0008] Further, the inner side of the cylindrical gear two is fixedly connected with the outer side of the thermocouple, and the inner side of the slip ring is slidingly connected with the outer side of the thermocouple.

[0009] Further, the two support assemblies are respectively located on the two sides of the flange bearing, and the support assemblies are used for auxiliary support to prevent the thermocouple from being bent.

[0010] Further, the support assembly comprises two fixed rings, and the inner sides of the fixed rings are fixedly connected with the outer side of the thermocouple.

[0011] Further, the proximal sides of the two fixed rings are fixedly connected with two support wires, and the material of the support wires is ceramic fiber.

[0012] The utility model has the advantages of the following beneficial effects:

[0013] 1. In the utility model, the cylindrical gear one is driven to rotate by starting the servo motor, the chain is moved, the chain stably transmits power to make the cylindrical gear two rotate, and then the thermocouple is continuously rotated, the thermocouple can rotate at a slower speed due to the adoption of the speed reducer and the size difference of the related gears, and the design can avoid the bending of the thermocouple due to gravity and coke falling and prevent the performance from being poor or even damaged.
