Description

Technical Field

[0001] This utility model relates to the technical field of fluorescent fiber optic temperature measurement, and in particular to a socket stabilization component and a fluorescent fiber optic temperature measurement device. Background Technology

[0002] Fluorescent fiber optic thermometry is a novel temperature measurement method based on fiber optic sensing and fluorescence thermometry principles. Compared to traditional electrical thermometry methods, it offers significant advantages such as electrical insulation, resistance to electromagnetic interference, distributed measurement capability, and long lifespan. It is particularly suitable for temperature monitoring in harsh environments such as high voltage and strong electromagnetic interference. The core of fluorescent fiber optic thermometry is the temperature-sensitive fluorescent material; rare-earth-doped fluoride glass and phosphate glass are commonly used fluorescent materials. When excited by light of a specific wavelength, rare-earth ions in these materials transition from the ground state to an excited state, and then return to the ground state via radiative transition, emitting characteristic fluorescence. The fluorescence performance of the fluorescent material is closely related to temperature. As the temperature increases, the number distribution of rare-earth ions in the ground and excited states changes, leading to changes in parameters such as fluorescence spectral intensity, fluorescence peak position, and fluorescence lifetime. By establishing a calibration relationship between fluorescence parameters and temperature, accurate temperature measurement can be achieved. Fluorescent fiber optic temperature measurement devices are temperature measuring equipment made using the principle of fluorescent fiber optic temperature measurement. A complete fluorescent fiber optic temperature measurement system usually consists of a light source, optical fiber, fluorescent temperature sensor, photodetector, signal processing unit, temperature calculation unit, and human-machine interface.

[0003] Fluorescent fiber optic temperature sensors have broad application prospects in multiple fields. For example, in temperature measurement of high-voltage instruments in electrical equipment, engine diagnostic systems, and transformer windings, fluorescent fiber optic temperature sensors can provide accurate temperature data, ensuring the normal operation of the equipment. In chemical processes, such as temperature measurement in highly corrosive environments or electrochemical treatments, and in safety temperature measurement under microwave radiation heating conditions, fluorescent fiber optic temperature sensors also play an important role. Furthermore, in the biological and medical fields, such as temperature measurement during surgery and research on physiological responses under electromagnetic radiation, fluorescent fiber optic temperature sensors also demonstrate unique advantages.

[0004] The fluorescent fiber optic temperature measuring device with a connector stabilization component is a new type of temperature measuring device that adds a connector stabilization component to the traditional fluorescent fiber optic temperature measuring device. The main function of the connector stabilization component is to ensure a stable and reliable connection between the fluorescent fiber optic temperature measuring device and the object being measured, avoiding temperature measurement errors caused by factors such as loose connection or vibration.

[0005] After prolonged use, the connection between the fiber optic probe and the fluorescent fiber optic temperature measuring device may become unstable due to the pulling of the fiber optic probe, which may affect subsequent use. Therefore, a fluorescent fiber optic temperature measuring device with a socket stabilization component can avoid temperature measurement errors caused by factors such as loose connection or vibration.

[0026] 1.

[0038] The present invention will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can implement it after referring to this specification.

[0039] like Figure 1-7 As shown, a fluorescent fiber optic temperature measuring device with a socket stabilization component includes a fluorescent fiber optic temperature measuring body 1 and a fluorescent fiber optic temperature measuring unit 21. The fluorescent fiber optic temperature measuring body 1 is configured with a device cavity 28. The fluorescent fiber optic temperature measuring unit 21 includes a temperature measuring fiber 22 and a connecting plug 23. The front end face of the fluorescent fiber optic temperature measuring body 1 is provided with a socket groove 2 that matches the connecting plug 23. The front end face of the fluorescent fiber optic temperature measuring body 1 is provided with an optical fiber passage groove 3 along the middle of the rear end of the socket groove 2. One end of the temperature measuring fiber 22 extends into the interior of the device cavity 28 through the optical fiber passage groove 3.

[0040] An external fixing plate 26 is fixed to the front end of the connector 23 along the outside of the temperature measuring optical fiber 22, and the front end face of the external fixing plate 26 is provided with embedding grooves 27 on both sides.

[0041] C-shaped sliding seat 6 is disposed on both sides of the front end of the fluorescent fiber optic temperature measuring body 1 along the insertion groove 2. Insertion stabilizer 11 is rotatably connected inside the C-shaped sliding seat 6. Insertion stabilizer 11 includes a longitudinal insertion fixing part 16, the size of which matches the size of the embedding groove 27.

[0042] The socket stabilizing component can be an outer fixing plate 26, with embedded grooves 27 on both sides of the front end face of the outer fixing plate 26; a C-shaped sliding seat 6; and a socket stabilizing member 11. The socket stabilizing member 11 is rotatably disposed in the C-shaped sliding seat 6. The socket stabilizing member 11 includes a longitudinal insertion fixing part 16, the size of which matches the size of the embedded groove 27.

[0043] In the above design, the inner cavity of the device accommodates components such as the temperature-sensing optical fiber. The fluorescent optical fiber temperature sensing unit is used to connect to the object being measured. The insertion slot is used to insert the temperature sensing unit. One end of the temperature-sensing optical fiber extends into the inner cavity of the device through the slot, enabling the transmission of the temperature measurement signal. This structure ensures that the temperature-sensing optical fiber can accurately and stably transmit the temperature measurement signal, providing a reliable guarantee for subsequent temperature measurement work.

[0044] The embedding groove is used to cooperate with the longitudinal insertion and fixing part of the socket stabilizer. Through the design of the outer fixing plate and the embedding groove, the connection stability between the temperature measuring unit and the temperature measuring body is improved, and the temperature measuring unit is effectively prevented from loosening.

[0045] The C-shaped sliding seat is used to support and slide the connector stabilizer. The longitudinal rotating part enables the connector stabilizer to rotate. The size of the longitudinal insertion fixing part matches the size of the embedding groove and is used to insert into the embedding groove to fix the temperature measuring unit. The design of the C-shaped sliding seat and the connector stabilizer allows the temperature measuring unit to be firmly fixed on the temperature measuring body, avoiding the problems of decreased temperature measuring accuracy and damage to the temperature measuring unit caused by unstable connection.

[0046] In a preferred embodiment, the upper and lower ends of the C-shaped sliding seat 6 are fixed with fixing ears 7, and the upper and lower ends of the front end of the fluorescent fiber optic temperature measuring body 1 along both sides of the insertion slot 2 are fixed with limiting sliding rods 8. The fixing ears 7 and the limiting sliding rods 8 are positioned in a front-to-back correspondence and slide along the limiting sliding rods 8. The front end of the limiting sliding rods 8 is fixed with a limiting fixing plate 9, and a pressure spring 10 is provided between the fluorescent fiber optic temperature measuring body 1 and the fixing ears 7 along the outside of the limiting sliding rods 8.

[0047] In the above design, the fixing ear and the limiting sliding rod are positioned correspondingly and slide along the limiting sliding rod to achieve the sliding of the C-shaped sliding seat. The limiting fixing plate is used to limit the sliding range of the C-shaped sliding seat, and the pressure spring is used to provide elasticity to ensure that the insertion stabilizing component can tightly fix the temperature measuring unit. Through the design of the fixing ear, the limiting sliding rod, and the pressure spring, the connection stability between the temperature measuring unit and the temperature measuring body is further enhanced, while improving the convenience of inserting and removing the temperature measuring unit.

[0048] In a preferred embodiment, the connector stabilizer 11 further includes a longitudinal rotating part 12, an outward expansion part 13, a bending part 14, and a transverse connecting part 15. The longitudinal rotating part 12 is located inside the C-shaped sliding seat 6 and is rotatably connected to the C-shaped sliding seat 6 via a shaft. The outward expansion part 13 is integrally connected to the front end of the longitudinal rotating part 12. The bending part 14 is integrally connected to the front end of the outward expansion part 13. The transverse connecting part 15 is integrally connected to the inner end of the bending part 14.

[0049] In the above scheme, the outward expansion is to ensure that the socket stabilizer expands outward so that the longitudinal insertion fixing part can be inserted into the embedding groove.

[0050] In a preferred embodiment, a first fixing hook 18 is fixed in the middle of the outer part 13, and a second fixing hook 20 is fixed on both sides of the front end of the fluorescent fiber temperature measuring body 1 along the C-shaped sliding seat 6. A tension spring 19 is provided between the first fixing hook 18 and the second fixing hook 20, and the two ends of the tension spring 19 are respectively hooked to the first fixing hook 18 and the second fixing hook 20.

[0051] In the above scheme, the design of the tension spring allows the connector stabilizer to open directly outward after being pulled forward and disengaged from the insertion slot. The connector stabilizer does not obstruct the position of the connector slot, facilitating the direct insertion of the next fluorescent fiber optic temperature measurement unit.

[0052] In a preferred embodiment, the front end of the fluorescent fiber optic temperature measuring body 1 is fixed with an external insertion tube 4 along the front end of the insertion slot 2. The external insertion tube 4 has the same inner diameter as the insertion slot 2, and the external insertion tube 4 is provided with a rectangular limiting groove 5 extending through it vertically.

[0053] In the above scheme, the outer tube has the same inner diameter as the socket groove to guide the insertion of the temperature measuring unit, and the rectangular limiting groove is used to cooperate with the C-shaped spring on the connector to achieve the initial fixation of the temperature measuring unit, which provides a foundation for the subsequent stable connection.

[0054] In a preferred embodiment, the upper and lower end faces of the connector 23 are provided with horizontal notches 24, and a C-shaped spring piece 25 is fixed in the horizontal notch 24. The two pins of the C-shaped spring piece 25 are arranged front and rear, and the horizontal dimension of the C-shaped spring piece 25 matches the horizontal dimension of the rectangular limiting groove 5.

[0055] In the above scheme, the C-shaped spring is used to deform and lock into the rectangular limiting groove during insertion; the horizontal dimensions of the C-shaped spring match the horizontal dimensions of the rectangular limiting groove to ensure the stability and firmness of the locking. The design of the C-shaped spring achieves the initial fixation of the temperature measuring unit.

[0056] In a preferred embodiment, a front handle 17 is fixed at the middle of the front end of the transverse connecting part 15.

[0057] In the above scheme, the front handle is used to provide an operating handle when inserting or removing the temperature measuring unit. By pulling the front handle, the rotation of the connector stabilizer and the insertion or removal of the longitudinal insertion fixing part can be easily controlled, thereby realizing the quick insertion and removal of the temperature measuring unit. The operation of inserting and removing the temperature measuring unit is more intuitive and convenient, improving work efficiency and user experience.

[0058] It should be noted that the fluorescent fiber optic temperature measurement unit is a mature device that has been developed. The fluorescent temperature sensor, photodetector, signal processing unit, temperature calculation unit, and human-machine interface have all been disclosed. The fluorescent fiber optic temperature measurement unit has also been disclosed and uses an existing configuration. Therefore, this utility model will not provide a specific description of it.

[0059] Working principle: When the fluorescent fiber optic temperature measuring unit needs to be inserted, align the connector on the fluorescent fiber optic temperature measuring unit with the outer insertion tube and insert it. The C-shaped spring in the horizontal notch deforms during the compression process until the fluorescent fiber optic temperature measuring unit is fully inserted. At this time, the C-shaped spring resets and is locked inside the rectangular limiting groove of the outer insertion tube for simple connection.

[0060] As the front handle is pulled outward, it rotates inward, causing the C-shaped sliding seat to slide forward along the limiting sliding rod. At the same time, the plug stabilizer rotates inward inside the C-shaped sliding seat until the longitudinal insertion fixing part on the plug stabilizer is located at the front end of the embedding groove. Pushing the front handle backward causes the longitudinal insertion fixing part to insert into the embedding groove. The presence of the pressure spring causes the plug stabilizer to lock the fluorescent fiber optic temperature measurement unit.

[0061] When it is necessary to remove the fluorescent fiber optic temperature measurement unit, pull the front handle outward until the longitudinal insertion fixing part is disengaged from the embedding groove. Then, under the action of the tension spring, the insertion stabilizing part opens outward. While pressing the C-shaped spring piece up and down, pull the fluorescent fiber optic temperature measurement unit outward.

[0062] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
