Description

Technical Field

[0001] The utility model belongs to the technical field of radiation temperature measurement of engine turbine blades, in particular to a high-rigidity positionable movable probe for radiation temperature measurement of turbine blades. Background Art

[0002] Temperature is a key factor that can significantly affect the properties of matter. At different temperatures, objects will exhibit different characteristics and responses. In some industrial processes or production environments that are extremely sensitive to temperature, accurate temperature monitoring is essential. For example, in industries such as aerospace and shipbuilding, my country has invested a lot of resources to improve the performance of aircraft engines and gas turbines. Among them, turbine blades play a key role in the engine, and their temperature is an important indicator reflecting the working state of the blades. However, these engines usually operate in harsh environments with high temperature, high pressure, and high-concentration airflow, which causes the turbine blades to often experience aging and wear problems internally. Therefore, accurately measuring the temperature of turbine blades under complex working conditions is crucial to extending the life of the engine.

[0003] At present, the temperature measurement methods are mainly divided into contact temperature measurement and non-contact temperature measurement. Contact temperature measurement requires the sensor to directly contact the surface of the object, which may cause damage to the object or affect its surface temperature distribution and cannot measure high-temperature surfaces or difficult-to-reach areas. It also has the disadvantages of slow response speed and high maintenance cost. It is not suitable for measuring the surface temperature of turbine blades. Radiation temperature measurement is a typical non-contact temperature measurement method. It is a method of measuring the surface temperature of an object by using the thermal radiation emitted by the object. The surface temperature of the object can be calculated by measuring the intensity of infrared radiation emitted by the object. Radiation temperature measurement has the advantages of high accuracy, fast response speed, and wide applicability. It does not require contact with the object and can measure temperature quickly and over a long distance. It is suitable for measuring difficult-to-reach or high-temperature objects.

[0004] There are many radiation temperature measurement devices on the market, but there are some problems: some devices are large in size and need to rely on complex post-data processing, some devices are only in the theoretical verification stage and have not yet been actually launched. Although some devices can achieve measurement, they are only suitable for specific engines and have poor versatility. Some devices have low measurement accuracy and limited applicable environments. In addition, the main challenges faced by radiation temperature measurement equipment designed for specific narrow environments at home and abroad also include the miniaturization of equipment structure and the cooling performance of key components. In a high-temperature, enclosed and narrow space, an oversized temperature measurement device will interfere with the working state of the target being measured, so the size of the device needs to be reduced as much as possible to achieve interference-free or minimal interference monitoring. In addition, instrument components entering a high-temperature environment need to work in a high-temperature and high-pressure environment of more than 1000°C for a long time, so cooling the core optical components and other structural components is also a key challenge.
