Description

Technical Field

[0001] The utility model relates to the technical field of temperature measuring equipment, in particular to a fluorescent optical fiber temperature measuring device. Background Art

[0002] The fluorescent fiber temperature measuring device is a high-precision sensor device that measures temperature based on the characteristics of fluorescent materials. It uses the specific relationship between the fluorescence intensity and temperature emitted by rare earth fluorescent materials after being irradiated with excitation light, and measures the change in fluorescence intensity to infer the temperature of the object being measured.

[0003] After being stimulated by light of a certain wavelength, the fluorescent molecules will radiate fluorescent energy. This fluorescent energy is not permanent, but will gradually decay over time. Moreover, when one end of the fluorescent optical fiber is exposed to the outside for a long time, the fluorescent molecules may decay faster due to the influence of environmental factors, resulting in a weakened fluorescent effect. Therefore, the Chinese utility model patent disclosed by the existing publication number CN220418666U: a fluorescent optical fiber temperature measuring device, the temperature measuring probe of the application is located in an isolation sleeve, and the temperature measuring probe is installed on the temperature measuring station through a mounting block. When measuring temperature, the elastic member expands the distance between the abutment block and the mounting block so that the temperature measuring probe is exposed from the isolation sleeve to maintain temperature measurement. When the measured device is turned off, it is not necessary to When temperature measurement is required, the adapter assembly is pulled to contract the elastic member and move the abutment block toward the mounting block, thereby pulling the isolation plate toward the port of the isolation sleeve through the first pull rope to seal the isolation sleeve, thereby sealing the optical fiber probe and reducing the time the fluorescent optical fiber is exposed to the air when not in use. However, since this application requires the use of two stretching operations to protect or extend the temperature measuring probe to achieve the above functions, when performing timed temperature measurement on some temperature measuring equipment, it is necessary to manually pull and stretch the protective sleeve frequently to achieve the movement of the protective sleeve, making the operation process inconvenient and not easy to forget to pull the protective sleeve regularly during manual operation, thereby affecting the data accuracy within the temperature measurement period.
