TECHNICAL FIELD

[0002] In industrial scenes such as power equipment operation and maintenance, industrial furnace temperature control, and chemical reaction kettle monitoring, accurate collection of temperature data is the key to ensuring safe operation of equipment and optimizing production efficiency. Fluorescent optical fiber temperature measurement devices have become the core temperature measurement equipment in such scenes due to their non-contact temperature measurement characteristics, strong anti-electromagnetic interference ability, and high precision of ±0.3℃. Among them, the fluorescent detection probe, as the core temperature sensing component of the device, directly affects the temperature measurement effect through its contact with the measured object. In the current mainstream design scheme in the industry, the fluorescent detection probe is mostly in the "fixed installation" mode.
[0003] The existing fluorescent optical fiber temperature measurement device generally fixes the temperature measurement probe in the equipment shell or the measured body, and only uses a simple dustproof net or metal shield for basic protection. However, dust in the environment will continuously adhere to the surface of the fluorescent coating at the temperature sensing end of the probe, causing attenuation of the light signal and gradual expansion of the temperature measurement error over time. At the same time, various gases can also corrode the probe, damage the structure, and shorten the service life of the probe. Even if some schemes add a manual protective cover to isolate the probe, manual opening and closing are still required, which cannot adapt to automated scenes. SUMMARY

[0030] In operation, first, the controller 10 is started, and the display 9 can feed back the relevant information in real time. Then, the controller 10 controls the sealing mechanism to open, and simultaneously, the pushing assembly is actuated to drive the fluorescence detection probe 15 to extend and enter the inside of the machine body. After the fluorescence detection probe 15 completes the temperature measurement in the machine body, the controller 10 controls the pushing assembly to drive the fluorescence detection probe 15 to retract, and simultaneously, drives the sealing mechanism to close, so as to seal the fluorescence detection probe 15. In this process, the exhaust assembly cooperates with the retraction action of the fluorescence detection probe 15 to exhaust the corrosion gas around the fluorescence detection probe 15 outward.

[0031] Further, referring to Figures 5-6 and Figures 8-9 , the pushing assembly comprises two electric telescopic rods 201, two mounting rings one 202, two push rods 203, two rotating rollers one 204, two rotating rollers two 205, and a mounting ring two 207. The two electric telescopic rods 201 are respectively horizontally fixedly installed on the inner walls of the other ends of the mounting shell one 11 on both sides. The two electric telescopic rods 201 are respectively located on both sides of the fluorescence temperature measurement end 14. The telescopic ends of the electric telescopic rods 201 are close to the mounting plate 12. The two mounting rings one 202 are respectively sleeved on the telescopic ends of the two electric telescopic rods 201. The mounting ring two 207 is sleeved on the fluorescence detection probe 15. The bottom of the mounting ring two 207 is provided with a sliding assembly. The bottom of one of the push rods 203 is rotatably installed on the outer wall of the circumferential top of one of the mounting rings one 202. The top of the other push rod 203 is rotatably installed on the outer wall of the circumferential bottom of the other mounting ring one 202. The two rotating rollers one 204 are respectively vertically rotatably installed on the outer walls of the circumferential top and bottom of the mounting ring two 207. The two rotating rollers one 204 are respectively located on one end of the two push rods 203 close to the mounting plate 12. The two rotating rollers two 205 are respectively located on one end of the two push rods 203 close to the mounting plate 12 and away from the mounting ring two 207.
[0032] First, start two electric telescopic rods 201, make it horizontally outward elongation, electric telescopic rod 201 will drive two installation ring 202 synchronous outward movement, installation ring 202 moves, will drive the rotation connection with its shift lever 203 moves, with the shift lever 203 continues to move, its close to the installation plate 12 one end will contact with the rotating roller two 205, by the limiting effect of rotating roller two 205, shift lever 203 starts to rotate around the connection point with installation ring 202, shift lever 203 rotating process, will push the rotating roller one 204 corresponding contact moves, therefore rotating roller one 204 will drive installation ring two 207 along the sliding assembly outward movement, in turn drive the fluorescence detection probe 15 synchronous extension, and the fluorescence detection probe 15 extension distance is greater than the elongation distance of electric telescopic rod 201, in this process, with the electric telescopic rod 201 elongation and shift lever 203 action, will linkage sealing mechanism open, finally the fluorescence detection probe 15 extends to the body, for subsequent temperature measurement ready, realize the temperature measurement when the fluorescence detection probe 15 telescopic and sealing opening and closing synchronous action, do not need manual operation open and close sealing, avoid dust adhesion and gas corrosion, reduce the temperature measurement error and prolong the service life of the fluorescence detection probe 15.
[0033] Further, with reference to Figures 4-6 And Figures 8-9 , sealing mechanism includes: two support plate one 301, two support plate two 302, two closed plate 303 and two groups of telescopic components, two support plate one 301 is respectively horizontally fixedly installed on the top inner wall and the bottom inner wall of the installation shell one 11, the support plate one 301 is close to the installation plate 12 one end is set in triangular shape, two rotating roller two 205 is respectively installed on the bottom of one of the support plate one 301 and the top of the other support plate one 301, two support plate two 302 is respectively vertically fixedly installed between the bottom of one of the support plate one 301 and the top of the other support plate one 301, two closed plate 303 is respectively located on both sides of the fluorescence detection probe 15, the top and bottom of two closed plate 303 are respectively installed on the two support plate one 301, two groups of telescopic components are respectively installed between the two closed plate 303 far from the installation plate 12 one end and the two installation ring one 202.
[0034] In operation, when the electric telescopic rod 201 is extended and drives the mounting ring one 202 to move outward, because the two groups of telescopic components are respectively connected to the mounting ring one 202 and the two closing plates 303 away from one end of the mounting plate 12, the mounting ring one 202 will exert a pushing force on the closing plate 303 through the telescopic component, and under the action of the pushing force, the closing plate 303 will rotate around the connecting point with the support plate one 301 in a direction away from the fluorescence detection probe 15. Since the end of the support plate one 301 close to the mounting plate 12 is triangularly arranged, and the two support plate twos 302 are respectively vertically fixed on both sides of the support plate one 301 to form a limit, the closing plate 303 will not deviate when rotating, and finally opens to the completely avoiding position from the initial state of close sealing, completing the opening action of the sealing mechanism to provide a channel for the extension of the fluorescence detection probe 15. When the electric telescopic rod 201 is retracted, the mounting ring one 202 drives the closing plate 303 to rotate in the opposite direction through the telescopic component, reseals to complete the closing action of the sealing mechanism.
[0035] Further, with reference to Figures 5-6 , the exhaust assembly comprises two exhaust pipes one 401, two exhaust pipes two 402, two one-way pistons 403, a connecting plate 404 and two connecting rods 405. The two exhaust pipes one 401 are L-shaped and fixedly installed on the two sides of the inner wall of the other end of the mounting shell one 11. The other ends of the two exhaust pipes one 401 pass through the support plate two 302 and the outer wall of one side of the mounting shell one 11 in sequence. The two exhaust pipes two 402 are fixedly installed on one end of the side close to each other of the circumferential inner wall of the two exhaust pipes one 401. The two one-way pistons 403 are arranged in the two exhaust pipes one 401. The intake direction of the one-way piston 403 is from the other end of the exhaust pipe one 401 to the one end of the exhaust pipe one 401. The two one-way pistons 403 are located at the other end of the two exhaust pipes one 401. The connecting plate 404 is fixedly installed between the telescopic ends of the two electric telescopic rods 201. One end of the two connecting rods 405 is fixedly installed on both sides of one end of the connecting plate 404. The other end of the two connecting rods 405 is fixedly connected with the two one-way pistons 403 through the two exhaust pipes one 401.
[0036] When the fluorescence detection probe 15 needs to be extended for temperature measurement, the telescopic end of the electric telescopic rod 201 moves outward, synchronously moving the connecting plate 404 outward, the connecting plate 404 pulls the one-way piston 403 in the exhaust pipe one 401 through the connecting rods 405 at both ends, and moves in the same direction as the fluorescence detection probe 15, at this time, the movement of the piston forms a negative pressure on the side of the exhaust pipe one 401 close to the probe, and the one-way piston 403 is in an open state under the action of the negative pressure, allowing external gas to enter the exhaust pipe one 401 from the other end of the exhaust pipe one 401 to the end of the exhaust pipe one 401, at this time, the gas entering the pipe is temporarily stored in the exhaust pipe one 401, preparing for the subsequent exhaust action when the fluorescence detection probe 15 is retracted, at the same time, the other end of the exhaust pipe one 401 can be installed with a filter screen to filter the inhaled gas, and the filter screen is convenient to replace, which is convenient for maintenance and better operation, when the temperature measurement is completed, the electric telescopic rod 201 is retracted to drive the fluorescence detection probe 15 to retract, the connecting plate 404 moves inward with the telescopic end, and the one-way piston 403 is reset in the exhaust pipe one 401 through the connecting rod 405, the one-way piston 403 extrudes the gas in the exhaust pipe one 401, and the pressure gas is discharged outward from the exhaust pipe two 402 due to the reverse blocking of the one-way piston 403, the discharged gas can blow away the harmful, high-temperature or corrosive gas remaining around the fluorescence detection probe 15, reducing the retention of such gas around the fluorescence detection probe 15, avoiding the harmful gas from wrapping the fluorescence detection probe 15 during the subsequent sealing process.
[0037] Further, referring to Figure 3 and Figure 7 , the other end of the optical fiber 13 is sleeved with a mounting sleeve 501, the mounting sleeve 501 is sleeved with a limiting ring one 502, the other end of the mounting shell one 11 is fixedly installed with a mounting pipe 503, the circumferential inner wall of the mounting pipe 503 is fixedly installed with a limiting ring two 504, and the circumferential array of the ends of the limiting ring one 502 and the limiting ring two 504 are fixedly installed with a plurality of buffer springs 505.
[0038] When the push assembly drives the fluorescence detection probe 15 to extend for temperature measurement, the optical fiber 13 will move synchronously, and then drive the mounting sleeve 501 sleeved with the other end of the optical fiber 13 and the limiting ring one 502 sleeved with the mounting sleeve 501 to move together, the limiting ring one 502 will compress the buffer spring 505 when moving, when the temperature measurement is completed, the push assembly drives the probe to retract, the optical fiber 13 moves inward synchronously with the probe, and the mounting sleeve 501 and the limiting ring one 502 also move reversely, the buffer spring 505 stretched before will release the elastic potential energy, push the limiting ring one 502 to reset stably, and buffer the reverse impact force when the fluorescence detection probe 15 retracts, preventing the optical fiber 13 from colliding with the inner wall of the mounting pipe 503, and protecting the stability of the optical fiber 13 and the fluorescence detection probe 15.
[0039] Further, referring to Figure 9The telescopic assembly includes: sleeves 601 and insert rods 602. The two sleeves 601 are respectively fixedly installed on the ends of the two closed plates 303 away from the mounting plate 12. One end of the two insert rods 602 is respectively inserted into the two sleeves 601, and the other end of the two insert rods 602 is respectively hinged to the sides of the two mounting rings 202 that are away from each other.
[0040] When the electric telescopic rod 201 extends to move the mounting ring 202 outward, the insertion rod 602, which is hinged to the side away from the mounting ring 202, moves outward synchronously with the mounting ring 202. At this time, one end of the insertion rod 602 inserted into the sleeve 601 slides outward along the inner wall of the sleeve 601. As the insertion rod 602 continues to move outward and adapts to the angle change through the hinge structure, the insertion rod 602 further pushes the sealing plate 303 to rotate around the connection point with the support plate 301 in a direction away from the fluorescence detection probe 15, thereby opening the sealing mechanism. When rod 201 retracts to move mounting ring 202 inward, insertion rod 602 moves inward synchronously with mounting ring 201. At this time, insertion rod 602 applies an inward pulling force to sleeve 601, pushing sealing plate 303 to rotate in the opposite direction around the connection point with support plate 301 toward the fluorescence detection probe 15, until sealing plate 303 fits together to form a seal, completing the closing of the sealing mechanism. Throughout the process, the sliding fit between insertion rod 602 and sleeve 601 can adapt to the rotation trajectory of sealing plate 303, avoiding rigid jamming and ensuring stable force transmission.
[0041] Further reference Figure 10 The sliding assembly includes a slide rail 701 and a slider 702. The slide rail 701 is horizontally fixedly installed on the top of one of the support plates 301. The slider 702 is slidably installed on the slide rail 701. The top of the slider 702 is fixedly installed on the outer wall of the bottom circumference of the mounting ring 207.
[0042] During operation, when the pushing component moves the mounting ring 207, the mounting ring 207 will cause the slider 702 to slide stably and horizontally along the slide rail 701. The slide rail 701 guides and limits the sliding direction of the slider 702, ensuring that the mounting ring 207 maintains its direction when it moves the fluorescence detection probe 15 to extend and retract, thus avoiding deviation.
[0043] Further reference Figure 5 , Figure 6 and Figure 10 The two closed plates 303 are respectively inclined in opposite directions and with the same angle and length, and are complementary spliced together. The edge contours of the two closed plates 303 are adapted to the edge of one end of the support plate 301. Sealing gaskets 801 are fixedly installed between the two closed plates 303 and the two support plates 301 respectively.
[0044] In the initial state, the two sealing plates 303 are in a closed state. Because the sides that are close to each other are complementary spliced with opposite tilt directions and the same angle and length, the two tilted edges are completely fitted together, and the edge contour of the sealing plate 303 matches the edge of one end of the support plate 301. The sealing gasket 801 between the sealing plate 303 and the support plate 301 is compacted, filling the gap between the two, and achieving a seal for the fluorescence detection probe 15. When the telescopic component drives the sealing plate 303 to open, the two sealing plates 303 rotate to both sides around the connection point with the support plate 301, and the complementary spliced tilted edges gradually separate. The sealing gasket 801 temporarily leaves the tight fit as the sealing plate rotates. When it is necessary to close the seal, the telescopic component drives the sealing plate 303 to rotate in the opposite direction, and the complementary tilted edges of the two sealing plates 303 are realigned and fitted together. The edges are once again matched with the contour of one end of the support plate 301, and the sealing state is restored through the sealing gasket 801 to ensure no gaps.
[0045] Working Principle: During operation, firstly, the controller 10 is activated, and the display 9 provides real-time feedback on relevant information. Subsequently, the controller 10 controls the sealing mechanism to open. Simultaneously, the pushing component operates: firstly, the two electric telescopic rods 201 in the pushing component are activated, causing them to extend horizontally outward. The electric telescopic rods 201 drive the two mounting rings 202 to move outward synchronously. As the mounting rings 202 move, they drive the lever 203 rotatably connected to them to move together. As the lever 203 continues to move, its end near the mounting plate 12 will contact the rotating roller 205. Under the limiting action of the rotating roller 205, the lever 203 begins to rotate around the connection point with the mounting ring 202. During the rotation of the lever 203, it pushes the corresponding... When the rotating roller 204 moves, the sliding assembly at the bottom of the mounting ring 207 operates—the mounting ring 207 drives the slider 702 to slide stably horizontally along the slide rail 701. The slide rail 701 guides and limits the sliding direction of the slider 702, ensuring that the mounting ring 207 maintains its direction and avoids deviation when it drives the fluorescence detection probe 15 to extend or retract. Then, the rotating roller 204 drives the mounting ring 207 to move outward along the sliding assembly, ultimately causing the fluorescence detection probe 15 to extend synchronously. The extension distance of the fluorescence detection probe 15 is greater than the extension distance of the electric telescopic rod 201. During this process, as the electric telescopic rod 201 extends and the lever 203 moves, the sealing mechanism opens in conjunction: the extension of the electric telescopic rod 201 drives the mounting ring 207 to extend horizontally along the slide rail 701. When ring 202 moves outward, because the telescopic assembly connects ring 202 and the sealing plate 303, the insert rod 602, which is hinged to the side away from ring 202, moves outward synchronously with ring 202. One end of the insert rod 602, inserted into sleeve 601, slides outward along the inner wall of sleeve 601. As the insert rod 602 continues to move outward and adapts to the angle change through the hinge structure, the insert rod 602 further pushes the sealing plate 303 to rotate around the connection point with support plate 301 in a direction away from the fluorescence detection probe 15. Since the two sealing plates 303 are initially in a closed state—the sides that are close to each other are complementary splicing settings with opposite tilt directions and the same angle and length—the two tilted edges are completely in contact, and there is a gap between the sealing plate 303 and support plate 301. The sealing gasket 801 is compacted. At this time, the rotation of the sealing plate 303 will cause the complementary splicing inclined edges to gradually separate. The sealing gasket 801 temporarily leaves the tight fit as the sealing plate rotates. Finally, the sealing plate 303 opens to both sides to a completely avoidance position, providing a channel for the extension of the fluorescence detection probe 15. At the same time, the exhaust assembly cooperates with the extension action of the fluorescence detection probe 15: the telescopic end of the electric telescopic rod 201 moves outward, driving the connecting plate 404 to move outward synchronously. The connecting plate 404 pulls the one-way piston 403 in the exhaust pipe 401 in the same direction as the fluorescence detection probe 15 through the connecting rods 405 at both ends. At this time, the movement of the piston creates a negative pressure in the exhaust pipe 401 near the probe. Under the action of the negative pressure, the one-way piston 403 is in the open state.External gas is allowed to enter the exhaust pipe 401 in a set direction. The gas entering the pipe is temporarily stored in the exhaust pipe 401 to prepare for subsequent exhaust. When the fluorescence detection probe 15 extends, the optical fiber 13 moves synchronously, which in turn moves the mounting sleeve 501 and the limiting ring 502 on the mounting sleeve 501 at the other end of the optical fiber 13. When the limiting ring 502 moves, it will compress the buffer spring 505. After the fluorescence detection probe 15 completes temperature measurement inside the machine, the controller 10 controls the pushing component to retract the fluorescence detection probe 15, and at the same time, it drives the sealing mechanism to close: the electric telescopic rod 201 retracts, driving the mounting ring... As mounting ring 202 moves inward, mounting ring 201 drives the sealing plate 303 to rotate in the opposite direction via the telescopic assembly. Insert rod 602 moves inward synchronously with mounting ring 202, applying an inward pulling force to sleeve 601, pushing the sealing plate 303 to rotate in the opposite direction around its connection point with support plate 301 towards the fluorescence detection probe 15. The complementary inclined edges of the two sealing plates 303 realign and fit together, their edges once again adapting to the contour of one end of support plate 301. The sealing gasket 801 between the sealing plate 303 and support plate 301 is compacted again, restoring the seal and ensuring no gaps, thus completing the fitting of the fluorescence detection probe 15. During the sealing process, the exhaust assembly works in conjunction with the retraction of the fluorescence detection probe 15: the electric telescopic rod 201 retracts, causing the connecting plate 404 to move inward with the telescopic end; the connecting plate 404 pushes the one-way piston 403 to reset within the exhaust pipe 1 401 via the connecting rod 405; the one-way piston 403 compresses the gas within the exhaust pipe 1 401; because the one-way piston reverses and cuts off, the pressurized gas is discharged outward from the exhaust pipe 2 402; the discharged gas can disperse harmful, high-temperature, or corrosive gases remaining around the fluorescence detection probe 15, reducing the retention of such gases around the fluorescence detection probe 15; simultaneously, the optical fiber 13 moves inward synchronously with the probe, ensuring safety. The sleeve 501 and the limiting ring 502 also move in the opposite direction. The previously compressed buffer spring 505 releases its elastic potential energy, pushing the limiting ring 502 to return to its original position smoothly. This buffers the reverse impact force when the fluorescence detection probe 15 retracts, preventing the optical fiber 13 from colliding with the inner wall of the mounting tube 503. Finally, the temperature measurement data is transmitted to the temperature transmitter 1 via the optical fiber 13 and displayed on the display 9, completing one temperature measurement operation. This achieves synchronous movement of the extension and retraction of the fluorescence detection probe 15 and the opening and closing of the seal during temperature measurement, eliminating the need for manual operation of the opening and closing of the seal, avoiding dust adhesion and gas corrosion, reducing temperature measurement errors, and extending the service life of the fluorescence detection probe 15.
