Description

Technical Field

[0001] This invention belongs to the technical field of fluorescent fiber optic thermometers, specifically relating to a fluorescent fiber optic temperature measuring device and method. Background Technology

[0002] The sensing element of a fluorescent fiber optic sensor is a rare-earth fluorescent material. Some rare-earth fluorescent materials are excited by certain forms of electromagnetic radiation, such as infrared, visible, and ultraviolet spectral regions, and emit visible linear spectra, i.e., fluorescence. After the electromagnetic radiation disappears, the lifetime of the excited state determines the duration of fluorescence emission. A certain parameter of fluorescence is modulated by temperature, and their relationship is monotonic. This relationship can be used for temperature measurement. The fluorescent fiber places the phosphor at the top of the fiber. Under the influence of ultraviolet light and the temperature of the object being measured, the temperature of the object being measured is calculated by using the fluorescence generated by the temperature probe.

[0003] Most existing fluorescent fiber optic temperature measuring devices have a relatively simple external structure, and therefore lack a structure to prevent dust accumulation at the interface. As a result, dust will accumulate inside the interface of the fluorescent fiber optic temperature measuring device after being left unused for a long time, which will affect the connection effect during use. Furthermore, the installation and disassembly are too cumbersome, which wastes a lot of time during troubleshooting and maintenance, thus affecting the overall work efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a fluorescent fiber optic temperature measurement device and method.

[0005] The technical solution adopted to solve the above-mentioned technical problems is: a fluorescent fiber optic temperature measuring device, including a mounting plate, two linear guide rails fixedly connected to the top of the mounting plate, a quick-release assembly slidably connected between the two linear guide rails, a device body mounted on the quick-release assembly, a dust cover fixedly connected to the top of the mounting plate, a heat dissipation assembly installed on the inner wall of the dust cover, and a fuse, a power input port, a relay output port, a network port, a serial port, an RS485 interface, and a fiber optic interface located at the rear end of the device body.

[0006] Furthermore, the quick-release assembly includes a slide plate slidably connected between two linear guide rails. Two first mounting slots are formed at both the front and rear ends of the top of the slide plate. Sliding grooves are formed on the inner walls of multiple first mounting slots. Fixed rods are slidably connected to the inner walls of multiple first mounting slots. Connecting rings are slidably connected to the bottom of the inner walls of multiple sliding grooves. A pull plate is fixedly connected between the tops of every two fixed rods. A second mounting slot is formed at the center of one side of the slide plate. A fixed plate is slidably connected to the inner wall of the second mounting slot. Two second springs are installed between the side of the fixed plate away from the main body of the device and the side of the inner wall of the second mounting slot. A pull handle is fixedly connected to the side of the fixed plate away from the main body of the device. A limit plate is fixedly connected to one side of the top of the two linear guide rails. A rubber pad is fixedly connected to one side of the outer wall of the limit plate.

[0007] The above technical solution involves first connecting the skateboard to two linear guide rails. Simultaneously, multiple fixing rods installed on the skateboard slide downwards along their corresponding first mounting slots under the tension of the first springs until they are fixedly connected between the two linear guide rails. Then, the fixing plate moves towards the main body of the device through two second springs until one side of the fixing plate is in contact with the corresponding surface of the main body of the device, thus achieving the fixing effect. When disassembly is required, simply pull the two pull plates upwards to remove the corresponding fixing rods from the two linear guide rails, thereby achieving the disassembly effect.

[0008] Furthermore, each of the connecting rings is slidably connected to the outer wall of the corresponding fixed rod, and the outer wall of each connecting ring matches the inner wall of the corresponding sliding groove.

[0009] The above technical solution, through matching design, ensures the stability between the connecting ring and the slide, not only reducing shaking and deviation, but also improving the limiting effect of the connecting ring on the fixed rod during equipment operation.

[0010] Furthermore, the pull handle is slidably connected to one side of the slide plate, and the pull handle is fixedly connected to the fixed plate on the side near the main body of the device.

[0011] The above technical solution allows the fixed plate to move by simply pulling the handle, which is not only easy to operate but also convenient for disassembly and installation, thus greatly improving the installation efficiency of the temperature measuring device.

[0012] Furthermore, a plurality of sliders are fixedly connected to the bottom of the main body of the device, and the inner walls of each pair of sliders are slidably connected to a linear guide rail, and the inner wall of the slider is in close contact with the outer wall of the linear guide rail.

[0013] The above technical solution enables the main body of the device to slide smoothly and steadily along the linear guide rail, reducing jamming and obstruction. At the same time, the close fit can reduce the shaking of the main body of the device during operation, making the main body of the device more stable and reliable during operation.

[0014] Furthermore, a tempered glass is fixedly connected to the top of the dust cover, and the tempered glass is positioned directly above the main body of the device.

[0015] The above technical solution allows users to directly observe the main body of the device without opening the dust cover. Furthermore, the tempered glass is not easily broken and can maintain a certain degree of integrity even when subjected to impact, thus improving safety during operation.

[0016] Furthermore, the heat dissipation assembly includes a partition fixedly connected to the center of one side of the inner wall of the dust cover. Connecting plates are fixedly connected to both the inner wall of the dust cover and the front and rear ends of the partition. An electric motor is installed between the tops of the two sets of connecting plates. Rotating rods are fixedly connected to the output shafts of the two electric motors. Multiple fan blades are fixedly connected to the outer walls of the two rotating rods. Two heat dissipation vents are opened on one side of the dust cover.

[0017] The above technical solution first starts two electric motors, which drive the corresponding rotating rods to rotate synchronously. At the same time, the two rotating rods drive the corresponding fan blades to rotate synchronously. Finally, the heat emitted by the main body of the device is discharged through the fan blades and two heat dissipation vents, thereby achieving the heat dissipation effect.

[0018] Furthermore, both sets of fan blades are located at the center between the front and rear ends of the partition and the inner wall of the dust cover.

[0019] The above technical solution allows for more even heat dissipation or ventilation around the main body of the device at the center, avoiding local overheating or poor ventilation, and helps to form a relatively balanced airflow distribution, making the heat dissipation or ventilation effect more stable.

[0020] A temperature measurement method using a fluorescent fiber optic thermometer includes the following specific steps: Step 1: According to the design requirements, first connect the main body of the device to the two linear guide rails by sliding the bottom-mounted slider. Then, install all the necessary wiring harnesses on the fuse, power input port, relay output port, network port, serial port, RS485 interface and fiber optic interface. Step 2: According to the design requirements, first slide the main body of the device between the two linear guide rails until the side of the main body near the heat dissipation component is in contact with the corresponding surface of the rubber pad. Then, slide the sliding plate between the two linear guide rails. At the same time, the multiple fixing rods installed on the sliding plate will slide down along the corresponding first mounting grooves under the tension of the first spring until they are fixedly connected between the two linear guide rails. Then, the fixing plate will move towards the main body of the device through the two second springs until one side of the fixing plate is in contact with the corresponding surface of the main body of the device, thereby achieving the fixing effect. When disassembly is required, simply pull the two pull plates upward to remove the corresponding fixing rods from the two linear guide rails, thereby achieving the disassembly effect. Step 3: According to the design requirements, start the two electric motors so that they drive the corresponding rotating rods to rotate synchronously. At the same time, the two rotating rods will drive the corresponding fan blades to rotate synchronously. Finally, the heat emitted by the main body of the device will be discharged through the fan blades and two heat dissipation vents, thereby achieving the heat dissipation effect. Step 4: After installation, turn on the switch on the main body of the device. Then, measure the temperature of the fluorescent fiber through the fuse, power input port, relay output port, network port, serial port and RS485 interface installed on the main body of the device. Finally, display the temperature information on the top of the main body of the device and observe it through the tempered glass to achieve the temperature measurement effect.

[0021] The beneficial effects of the present invention are as follows: (1) By setting up quick-release components, the present invention can quickly remove the device for inspection, repair or replacement of parts, shorten the equipment downtime, and can also quickly respond to sudden failures or situations that require adjustment, thus improving the response capability; (2) By setting up dust covers and tempered glass, the present invention prevents dust and other impurities from entering the device, avoids pollution and damage to optical components and electronic devices, ensures stable device performance, and allows users to clearly observe the working status of the device without opening the dust cover, which is convenient for real-time monitoring.

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0025] like Figure 1 - Figure 8As shown, a fluorescent fiber optic temperature measuring device of this embodiment includes a mounting plate 1. Two linear guide rails 2 are fixedly connected to the top of the mounting plate 1. A quick-release assembly 3 is slidably connected between the two linear guide rails 2. The device body 4 is mounted on the quick-release assembly 3. The quick-release assembly 3 includes a slide plate 301 slidably connected between the two linear guide rails 2. Two first mounting grooves 302 are opened at both the front and rear ends of the top of the slide plate 301. Sliding grooves 303 are opened on the inner walls of the multiple first mounting grooves 302. Fixed rods 304 are slidably connected to the inner walls of the multiple first mounting grooves 302. Connecting rings 305 are slidably connected to the bottom of the inner walls of the multiple sliding grooves 303. The outer walls of the multiple fixed rods 304 are slidably connected to the outer walls of the multiple fixed rods 304. A first spring 306 is connected to the slide plate 301. A pull plate 307 is fixedly connected between the tops of every two fixed rods 304. A second mounting groove 308 is provided at the center of one side of the slide plate 301. A fixed plate 309 is slidably connected to the inner wall of the second mounting groove 308. Two second springs 3010 are installed between the side of the fixed plate 309 away from the main body 4 and the inner wall of the second mounting groove 308. A pull handle 3011 is fixedly connected to the side of the fixed plate 309 away from the main body 4. A limit plate 3012 is fixedly connected to one side of the top of the two linear guides 2. A rubber pad 3013 is fixedly connected to one side of the outer wall of the limit plate 3012. First, slide plate 301 is slidably connected to the two linear guides. Between the two linear guide rails 2, at the same time, multiple fixing rods 304 installed on the slide plate 301 will slide downward along the corresponding first mounting grooves 302 under the tension of the first spring 306 until they are fixedly connected between the two linear guide rails 2. Then, the fixing plate 309 will move towards the device body 4 through the two second springs 3010 until one side of the fixing plate 309 is in contact with the corresponding surface of the device body 4, thus achieving the fixing effect. When disassembly is required, simply pull up the two pull plates 307 to remove the corresponding fixing rods 304 from the two linear guide rails 2, thereby achieving the disassembly effect. Multiple connecting rings 305 are slidably connected to the corresponding... The outer walls of the fixed rod 304 and the outer walls of the multiple connecting rings 305 are matched with the inner walls of the corresponding sliding grooves 303. This matching design ensures the stability between the connecting rings 305 and the sliding grooves 303, reducing shaking and deviation, and improving the limiting effect of the connecting rings 305 on the fixed rod 304 during equipment operation. The pull handle 3011 is slidably connected to one side of the slide plate 301, and the pull handle 3011 is fixedly connected to the fixed plate 309 near the main body 4 of the device. By controlling the pull handle 3011, the fixed plate 309 can be moved, which is not only simple to operate, but also easy to disassemble and install, thus greatly improving the installation efficiency of the temperature measuring device. like Figure 3 and Figure 5As shown, a dust cover 5 is fixedly connected to the top of the mounting plate 1, and multiple sliders 401 are fixedly connected to the bottom of the device body 4. The inner walls of each pair of sliders 401 are slidably connected to the linear guide rail 2, and the inner wall of the slider 401 is tightly fitted to the outer wall of the linear guide rail 2. This allows the device body 4 to slide smoothly and steadily along the linear guide rail 2, reducing jamming and obstruction. The tight fit also reduces the shaking of the device body 4 during operation, making the device body 4 more stable and reliable during operation. A tempered glass 501 is fixedly connected to the top of the dust cover 5, and the tempered glass 501 is positioned directly above the device body 4. This allows the user to directly observe the device body 4 without opening the dust cover 5, and the tempered glass 501 is not easily broken. Even if it is impacted, it can maintain a certain degree of integrity, improving safety during operation. like Figure 3 , Figure 5 and Figure 6 As shown, a heat dissipation assembly 6 is installed on the inner wall of the dust cover 5. The heat dissipation assembly 6 includes a partition 601 fixedly connected to the center of one side of the inner wall of the dust cover 5. Connecting plates 602 are fixedly connected to both the inner wall of the dust cover 5 and the front and rear ends of the partition 601. An electric motor 603 is installed between the tops of the two sets of connecting plates 602. A rotating rod 604 is fixedly connected to the output shaft of each of the two electric motors 603. Multiple fan blades 605 are fixedly connected to the outer walls of each of the two rotating rods 604. Two heat dissipation vents 606 are opened on one side of the dust cover 5. First, the two electric motors 603 are started, so that the two electric motors 603 drive the corresponding rotating rods 604 to rotate synchronously. At the same time, the two rotating rods 604 will drive the corresponding fan blades 605 to rotate synchronously. Finally, the heat emitted from the main body 4 of the device will be discharged through the fan blades 605 and the two heat dissipation vents 606, thereby achieving the heat dissipation effect. Both sets of fan blades 605 are located at the center between the front and rear ends of the partition 601 and the inner wall of the dust cover 5. Being located at the center can dissipate heat or ventilate the area around the main body 4 of the device more evenly, avoiding local overheating or poor ventilation, and helping to form a relatively balanced airflow distribution, making the heat dissipation or ventilation effect more stable. The rear end of the main body 4 of the device is equipped with a fuse 7, a power input port 8, a relay output port 9, a network port 10, a serial port 11, an RS485 interface 12, and a fiber optic interface 13.

[0026] A temperature measurement method using a fluorescent fiber optic thermometer includes the following specific steps: Step 1: According to the design requirements, firstly, slide the main body 4 of the device between the two linear guide rails 2 via the bottom-mounted slider 401. Then, install all the necessary wiring harnesses on the fuse 7, power input port 8, relay output port 9, network port 10, serial port 11, RS485 interface 12 and fiber optic interface 13. Step 2: According to the design requirements, firstly, slide the main body 4 of the device between the two linear guide rails 2 until the side of the main body 4 near the heat dissipation component 6 is in contact with the corresponding surface of the rubber pad 3013. Then, slide the slide plate 301 between the two linear guide rails 2. At the same time, the multiple fixing rods 304 installed on the slide plate 301 will slide down along the corresponding first mounting groove 302 under the tension of the first spring 306 until they are fixedly connected between the two linear guide rails 2. Then, the fixing plate 309 will move towards the side of the main body 4 through the two second springs 3010 until the side of the fixing plate 309 is in contact with the corresponding surface of the main body 4, thereby achieving the effect of fixing. When disassembly is required, simply pull the two pull plates 307 upward to pull the corresponding fixing rods 304 out of the two linear guide rails 2, thereby achieving the effect of disassembly. Step 3: According to the design requirements, start the two electric motors 603, so that the two electric motors 603 drive the corresponding rotating rods 604 to rotate synchronously. At the same time, the two rotating rods 604 will drive the corresponding fan blades 605 to rotate synchronously. Finally, the heat emitted from the main body 4 of the device will be discharged through the fan blades 605 and the two heat dissipation vents 606, thereby achieving the heat dissipation effect. Step 4: After installation, turn on the switch on the main body 4 of the device. Then, measure the temperature of the fluorescent fiber through the fuse 7, power input port 8, relay output port 9, network port 10, serial port 11 and RS485 interface 12 installed on the main body 4 of the device. Finally, display the temperature information on the top of the main body 4 of the device and observe it through the tempered glass 501 to achieve the temperature measurement effect.
