Description

Technical Field

[0001] The utility model relates to the technical field of point-type fluorescent temperature measuring sensors, in particular to a fluorescent optical fiber temperature measuring probe, a temperature sensor and a temperature measuring system. Background Art

[0002] Fluorescent fiber optic temperature probe has the advantages of high temperature resistance, corrosion resistance, insulation, and anti-magnetic interference. Temperature sensors using fluorescent fiber optic temperature probes have broad application prospects in many fields such as oil-immersed transformer temperature measurement.

[0003] The Chinese utility model patent No. 201120297841.5 discloses a point-type fluorescent fiber temperature sensor, whose fluorescent fiber temperature measuring probe mainly includes plastic optical fiber, ceramic tube, glue and fluorescent powder. The higher the flatness of the end of the plastic optical fiber, the more conducive to improving the signal-to-noise ratio of the overall detection. The general processing method is: first grind the end of the plastic optical fiber flat, then plug it into the tube cavity of the ceramic tube, and then fill it with glue and encapsulate it.

[0004] However, the above structure and process are generally only applicable to the case where the optical fiber is relatively thick. As the fluorescent optical fiber temperature probe continues to develop in the direction of smaller size and smaller volume, the diameter of the optical fiber used is getting thinner and thinner. At present, the diameter of the thinner optical fiber is about 100 microns to 200 microns. When grinding the end of the optical fiber that is too thin, it is more difficult to fix the position of the optical fiber, which makes it difficult to directly grind the end of the optical fiber with high quality, and it is also difficult to make the end of the optical fiber have a high degree of flatness.

[0005] Therefore, there is an urgent need to provide a fluorescent fiber optic temperature measurement probe that can ensure the flatness of the end of the optical fiber while the optical fiber is very thin, so as to achieve a small-size design of the fluorescent fiber optic temperature measurement probe.

[0056] refer to Figure 1-3 Some embodiments of the present application provide a fluorescent fiber temperature measuring probe, which includes a tail handle 100, a core ferrule 200 and an optical fiber 300. The tail handle 100 is provided with an insertion through hole 110; the core ferrule 200 is fixed to the tail handle 100, and the core ferrule 200 is provided with a core hole 210 connected with the insertion through hole 110; the optical fiber 300 has a sensing end 310, the sensing end 310 passes through the insertion through hole 110 and is inserted into the core hole 210, and the sensing end 310 has a terminal end face 311, and the terminal end face 311 is located at the opening position of the core hole 210; the outer sleeve 400 is fixedly connected to the tail handle 100, the outer sleeve 400 is provided with a sleeve hole 410, and the core ferrule 200 is inserted in the sleeve hole 410; the fluorescent component 500 is arranged in the sleeve hole 410, and the fluorescent component 500 covers the terminal end face 311.

[0057] In the embodiment of the present application, the sensing end 310 of the optical fiber 300 passes through the insertion through hole 110 and is inserted into the core hole 210. The sensing end 310 has a terminal end face 311, and the terminal end face 311 is located at the opening of the core hole 210; the terminal end face 311 is located at the opening of the core hole 210, which may mean that after the terminal end face 311 is polished, it is just located at the plane where the opening of the core hole 210 is located, or in some embodiments, the terminal end face 311 slightly protrudes from the opening, and the slight protrusion may be no more than 0.5mm. Therefore, during the processing, the terminal end face 311 of the optical fiber 300 inserted into the core hole 210 can be directly polished; during the polishing process, the tail handle 100 can be clamped, the core 200 is fixed to the tail handle 100, and the sensing end 310 of the optical fiber 300 is inserted into the core hole 210. During the polishing process, the core 200 cooperates with the tail handle 100 to effectively fix the sensing end 310 of the optical fiber 300, which is conducive to polishing a higher flatness. In addition, the outer sleeve 400 is fixedly connected to the tail handle 100, and the structure is stable and reliable; the ferrule 200 is inserted into the sleeve hole 410 of the outer sleeve 400, and the fluorescent component 500 is arranged in the sleeve hole 410. The fluorescent component 500 covers the terminal end face 311, thereby making the fluorescent component 500 stably and reliably fixed in the sleeve hole 410, so that the detection light in the optical fiber 300 can directly irradiate the fluorescent component 500 during subsequent temperature measurement. It can ensure the flatness of the end of the optical fiber 300 under the premise that the optical fiber 300 is very thin, so as to realize the small size design of the fluorescent optical fiber temperature measurement probe.

[0058] In some embodiments, reference Figure 1-3 The fluorescent fiber temperature probe also includes an adhesive 600, and the gap between the core hole 210 and the optical fiber 300 is filled with the adhesive 600. The adhesive 600 further fixes the position and can effectively prevent the optical fiber 300 from sliding in the core hole 210. In some cases, the interference fit between the core hole 210 and the optical fiber 300 can also prevent the optical fiber 300 from sliding, but this method is difficult to insert the optical fiber 300 into the core hole 210 and is easy to cause damage to the optical fiber 300.

[0059] Further, refer to Figure 1-3In some embodiments, the gap between the insertion through hole 110 and the optical fiber 300 is filled with adhesive 600; similarly, in some embodiments, the ferrule 200 and the tail handle 100 are bonded by adhesive 600; similarly, in some embodiments, the gap between the sleeve hole 410 and the ferrule 200 is filled with adhesive 600. On the one hand, the adhesive 600 plays a role in adhesive fixation to improve the overall stability and reliability. On the other hand, in the oil-immersed transformer temperature measurement scenario, the fluorescent fiber optic temperature measurement probe is immersed in high-frequency vibrating transformer oil. If there are too many bubbles in the fluorescent fiber optic temperature measurement probe, its measurement accuracy will be affected. By filling at least part of the various gaps with adhesive 600, the air inside can be driven out, the number of bubbles can be reduced, and the overall quality of the fluorescent fiber optic temperature measurement probe can be improved.

[0060] refer to Figure 1-3 In some embodiments, the core hole 210 includes a reduced diameter hole section 211 and a circular hole section 212 that are connected in sequence, the opening of the reduced diameter hole section 211 is connected to the insertion through hole 110, and the opening of the circular hole section 212 faces the fluorescent member 500. The reduced diameter hole section 211 is provided to facilitate the optical fiber 300 to be guided through the reduced diameter hole section 211 and inserted into the circular hole section 212.

[0061] In some embodiments, reference Figure 1-3 The insertion through hole 110 includes a fiber core hole section 111 and a ferrule hole section 112 which are connected in sequence. One end of the ferrule hole section 112 away from the fiber core hole section 111 faces the ferrule 200. The aperture of the fiber core hole section 111 is smaller than the aperture of the ferrule hole section 112. One end of the ferrule 200 is plugged into and matched with the ferrule hole section 112, thereby making the overall assembly structure more stable and reliable.

[0062] refer to Figure 1-3 In some embodiments, a sinking recess 120 is provided at one end of the tail handle 100 connected to the ferrule 200, and the outer sleeve 400 is plugged into and matched with the sinking recess 120, thereby making the overall assembly structure more stable and reliable. In some embodiments, the sinking recess 120 can be a countersunk hole coaxially connected to the ferrule jack section 112. In other embodiments, it can also be an annular groove provided on the end surface of the tail handle 100.

[0063] refer to Figure 1-3In some embodiments, the optical fiber 300 is a bare optical fiber, which refers to an optical fiber structure without an external protective cover, that is, a protective cover that has been stripped off. The material of the optical fiber 300 may be quartz or plastic. Taking quartz as an example, the optical fiber 300 may be composed of a core, a cladding wrapped around the core, and a coating layer applied to the cladding, or may be composed of a core and a cladding wrapped around the core. Among them, the cladding is usually composed of a material with a lower refractive index (such as silicon or microsilicon) to ensure the propagation of the optical signal in the core. The diameter of the optical fiber 300 may be 100 microns or 200 microns, or other diameters, which may be determined according to design requirements. In order to protect the optical fiber 300, a sheath assembly 800 may also be sheathed on the optical fiber 300, and the sheath assembly 800 may include one or more sheaths. The sheath assembly 800 may specifically include only a spiral sleeve sleeved on the optical fiber 300; in other embodiments, it may also include a heat shrink tube for connecting the spiral sleeve and the tail handle 100, and may also include a plastic sleeve or a sleeve made of other flexible materials sleeved on the optical fiber 300 and located inside the spiral sleeve.

[0064] In some embodiments, the ferrule 200 is a ceramic tube, the outer sleeve 400 is a quartz sleeve, and the tail handle 100 is a plastic tail handle. Selecting materials that are resistant to high temperatures, corrosion, and have certain structural strength and toughness to design the ferrule 200, the outer sleeve 400, and the tail handle 100 can make the fluorescent fiber temperature measurement probe better suitable for relatively harsh temperature measurement environments such as oil-immersed transformer temperature measurement.

[0065] refer to Figure 1-3 In some embodiments, the ferrule 200, the outer sleeve 400 and the tail handle 100 cooperate to form a long columnar structure, the outer diameter of the outer sleeve 400 is not greater than the outer diameter of the tail handle 100, and the structure is simple.

[0066] refer to Figure 1-3 In some embodiments, the sleeve hole 410 can be a blind hole, and the fluorescent component 500 is fixed to the bottom of the sleeve hole 410, which has a simple structure.

[0067] Of course, in other embodiments, the sleeve hole 410 may be a through hole, and the fluorescent component 500 is sealed in the sleeve hole 410 by a sealant.

[0068] Further, Figure 1-3 In some embodiments, reference is made to Figure 2 and Figure 4 The optical fiber 300 also has a transfer end 320, and the fluorescent optical fiber temperature measuring probe also includes a connector 700, which is arranged at the transfer end 320, and can be connected to other devices such as a demodulator or an optical cable through the connector 700. The type and structure of the connector 700 can be selected according to actual needs, and are not specifically limited.

[0069] Further, Figure 1-4 Based on any embodiment of Figure 5 The core 200 is provided with a first glue dispensing hole 220, one end of which is connected to the core hole 210, the other end of which is connected to the outside of the core 200, and the first glue dispensing hole 220 is filled with adhesive 600; of course, in some embodiments, the core 200 may also be provided with a first glue dispensing slit 230, one end of which is connected to the core hole 210, the other end of which is connected to the outside of the core 200, and the first glue dispensing slit 230 is filled with adhesive 600. The first glue dispensing hole 220 and / or the first glue dispensing slit 230 can facilitate the filling of adhesive 600 from different positions, and the internal air is driven out by reciprocatingly filling adhesive 600 during the manufacturing process to reduce internal bubbles as much as possible.

[0070] Further, refer to Figure 5 In some embodiments, the outer sleeve 400 is provided with a second glue-dispensing hole 420, one end of which is connected to the sleeve hole 410, the other end of which is connected to the external space of the outer sleeve 400, and the second glue-dispensing hole 420 is filled with adhesive 600; of course, in some embodiments, the outer sleeve 400 may be provided with a second glue-dispensing slit 430, one end of which is connected to the sleeve hole 410, the other end of which is connected to the external space of the outer sleeve 400, and the second glue-dispensing slit 430 is filled with adhesive 600. The functions of the second glue-dispensing hole 420 and the second glue-dispensing slit 430 are the same as above, and will not be described in detail.

[0071] In addition, reference Figure 6 Some embodiments of the present application further provide a temperature sensor, which includes a demodulation host 900 and a fluorescent fiber optic temperature measurement probe of any of the above embodiments, and the fluorescent fiber optic temperature measurement probe is connected to the demodulation host 900.

[0073] The above-mentioned embodiment only expresses one implementation method of the utility model, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent.
