Abstract
Description
Technical Field
[0001] This utility model relates to the field of sensing probe technology, and more specifically, to an optical fiber temperature sensing probe. Background Technology
[0002] Fiber optic temperature sensing probes, also known as fiber optic temperature sensors, are sensors that measure temperature using optical principles. They utilize the scattering effect: when light passes through a medium, the movement of molecules in the medium causes thermodynamic noise interference, resulting in a slight shift in the wavelength of the transmitted light. Fiber optic temperature sensors measure temperature changes by detecting this wavelength shift.
[0003] Among them, the patent with announcement number CN218954563U discloses an assembled probe mounting component, including a fixing head and a probe sleeve. The fixing head includes an integrally formed stud part and a sleeve connecting part. The sleeve connecting part is located at one axial end of the stud part. The sleeve connecting part is provided with a variable diameter hole for threaded connection with the probe sleeve. The variable diameter hole includes an optical aperture section and a screw hole section located inside the optical aperture section. The probe sleeve has an external thread that matches the screw hole section. The maximum outer diameter of the probe sleeve is not greater than the inner diameter of the optical aperture section. The rear part of the probe sleeve is used to insert an optical fiber probe.
[0004] When in use, this structure can be threaded onto the body of the equipment via the stud. Heat is conducted through the stud to the probe sleeve and then to the fiber optic probe, which can obtain accurate temperature values. This makes it easy to use in different installation environments of large equipment. However, this also means that the probe is fixed and not easy to make direct contact with the object being tested. In addition, the device is usually installed in a high-temperature area, which also causes the device to be severely heated, reducing its service life. Utility Model Content
[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an optical fiber temperature sensing probe, which aims to solve the problems mentioned in the background art.
[0006] This utility model provides the following technical solution: a fiber optic temperature sensing probe, including a support block, on which a control and protection component is provided;
[0007] The control and protection component includes a first clip frame disposed on one side of the support block, a guide cylinder being clipped to one end of the first clip frame, an adjustable limiting clamp being disposed at the end of the guide cylinder, and a probe for detection being disposed at one end of the limiting clamp.
[0008] The bottom of the first card frame is snapped with a second card frame, and a side baffle is installed on one side of the second card frame by bolts. Both the side baffle and the first card frame are equipped with water-cooling modules. One end of the limiting clamp is fixedly provided with an extension tube, which is located inside the guide tube. One end of the extension tube is inserted with a top plug, which is located inside the guide tube and is slidably connected to the guide tube.
[0009] As can be seen, in the above technical solution, the top plug is driven to move by the electric push rod. When the top plug moves, it drives the limiting clamp, the extension tube and the probe to move and make the extension tube extend out of the guide tube, making it easier for the probe to approach the heat source. At the same time, when the temperature in the optical fiber changes, the refractive index of the optical fiber will also change, thereby changing the transmission characteristics of the optical signal in the optical fiber. By detecting this change by the probe, the temperature information can be obtained.
[0010] Optionally, in one possible implementation, the bottom of the second card frame is snapped with a motherboard, the second card frame and the support block are detachably connected by bolts, an electric push rod is provided on one side of the side baffle, the output end of the electric push rod passes through the side baffle, the second card frame and the first card frame and extends to one end of the top plug, and each of the multiple water cooling modules is provided with a conduit, and each of the water cooling modules is connected through the conduit.
[0011] As can be seen, in the above technical solution, through the combined use of various conduits and water-cooling modules, cooling water can easily flow in the water-cooling modules and conduits to achieve the function of cooling and avoid damage to the device due to excessive temperature. At the same time, through the setting of the top plug, it can guide and limit the displacement of the extension tube, the limiting clamp and the probe, and ensure the stability of its displacement.
[0012] The technical effects and advantages of this utility model are as follows:
[0013] By setting up control and protection components, compared with existing technologies, through the corresponding cooperation of various structures, the displacement of the limiting clamp, extension tube and probe is achieved, and the extension tube extends out of the guide tube, making it easier for the probe to approach the heat source. At the same time, when the temperature in the optical fiber changes, the refractive index of the optical fiber also changes, thereby changing the transmission characteristics of the optical signal in the optical fiber. By detecting this change by the probe, temperature information can be obtained.
[0014] Meanwhile, through the coordinated use of various conduits and water-cooling modules, cooling water can easily flow within the water-cooling modules and conduits to achieve the function of cooling down, avoiding damage to the device due to excessive temperature. At the same time, the top plug can guide and limit the displacement of the extension tube, limiting clamp, and probe, ensuring the stability of their displacement. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] As attached Figure 1-4 The fiber optic temperature sensing probe shown uses a control and protection component on the support block 1. When the top plug 6 is displaced, it drives the limiting clamp 4, the extension tube 7, and the probe 5 to move, causing the extension tube 7 to extend out of the guide tube 3, making it easier for the probe 5 to approach the heat source. At the same time, when the temperature in the fiber changes, the refractive index of the fiber also changes, thereby changing the transmission characteristics of the optical signal in the fiber. By detecting this change by the probe 5, temperature information can be obtained. In addition, through the cooperation of various conduits 12 and water cooling module 11, cooling water can easily flow in the water cooling module 11 and conduits 12 to achieve the function of cooling and avoid damage to the device due to excessive temperature. The specific structural settings of the components are as follows.
[0023] The control and protection component includes a first clip frame 2 set on one side of the support block 1, a guide cylinder 3 is clipped to one end of the first clip frame 2, an adjustable limiting clamp 4 is set at the end of the guide cylinder 3, and a probe 5 for detection is set at one end of the limiting clamp 4.
[0024] The bottom of the first card frame 2 is snapped with the second card frame 8. A side baffle 13 is installed on one side of the second card frame 8 by bolts. Both the side baffle 13 and the first card frame 2 are equipped with water-cooling modules 11. An extension tube 7 is fixedly installed at one end of the limiting clamp 4. The extension tube 7 is located inside the guide tube 3. A top plug 6 is inserted into one end of the extension tube 7. The top plug 6 is located inside the guide tube 3 and is slidably connected to the guide tube 3.
[0025] The bottom of the second frame 8 is snapped with the main board 9. The second frame 8 and the support block 1 are detachably connected by bolts. An electric push rod 10 is provided on one side of the side frame 13. The output end of the electric push rod 10 passes through the side frame 13, the second frame 8 and the first frame 2 and extends to one end of the top plug 6. A conduit 12 is provided on each of the multiple water-cooling modules 11, and each water-cooling module 11 is connected through the conduit 12.
[0026] According to the above structure, when in use, the staff installs the device at the designated location. During monitoring, the electric push rod 10 drives the top plug 6 to move. When the top plug 6 moves, it drives the limiting clamp 4, the extension tube 7 and the probe 5 to move, and the extension tube 7 extends out of the guide tube 3, making it easier for the probe 5 to approach the heat source. At the same time, when the temperature in the optical fiber changes, the refractive index of the optical fiber also changes, thereby changing the transmission characteristics of the optical signal in the optical fiber. By detecting this change through the probe 5, the temperature information can be obtained.
[0027] Meanwhile, through the coordinated use of various conduits 12 and water-cooling module 11, cooling water can easily flow in the water-cooling module 11 and conduits 12 to achieve the function of cooling and avoid damage to the device due to excessive temperature. At the same time, through the setting of top plug 6, it can guide and limit the displacement of extension tube 7, limiting clamp 4 and probe 5, ensuring the stability of their displacement.
[0028] Unlike existing technologies, this application discloses an optical fiber temperature sensing probe. When the top plug 6 is displaced, it causes the limiting clamp 4, the extension tube 7, and the probe 5 to move, allowing the extension tube 7 to extend out of the guide tube 3, making it easier for the probe 5 to approach the heat source. At the same time, when the temperature in the optical fiber changes, the refractive index of the optical fiber also changes, thereby changing the transmission characteristics of the optical signal in the optical fiber. By detecting this change through the probe 5, temperature information can be obtained. In addition, through the cooperation of various conduits 12 and water cooling module 11, cooling water can easily flow in the water cooling module 11 and conduits 12 to achieve the cooling function and avoid damage to the device due to excessive temperature.
[0029] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
