Description

Technical Field

[0001] This utility model relates to the field of fiber optic sensing technology, and in particular to a fluorescent fiber optic temperature measuring device. Background Technology

[0002] The core principle of fluorescent fiber optic temperature measurement devices is to utilize the physical phenomenon that the optical properties of specific fluorescent materials change with temperature. When excitation light irradiates the fluorescent material inside the fiber optic probe, fluorescence is emitted. However, temperature sensors are prone to failure, risk, or insufficient accuracy in harsh environments such as strong electromagnetic fields. Therefore, fluorescent fiber optic temperature measurement devices need to be based on the characteristic that fluorescence lifetime changes with temperature. Their probes are inherently insulated, resistant to electromagnetic interference, and passive, and can work safely, reliably, and accurately in strong electromagnetic field scenarios.

[0003] In the existing technology, the sensor head lacks a convenient disassembly design. When it is necessary to replace the sensor head with a suitable one according to the object being measured, it is difficult to achieve quick separation of the two. Usually, it is necessary to repurchase the entire set of equipment. Moreover, if the sensor head is damaged or aged, the entire set of equipment also needs to be replaced. This not only increases the cost of use, but also limits its flexible application on different objects being measured. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a fluorescent fiber optic temperature measurement device, which aims to improve the problems of not being able to replace the sensor head with a suitable one according to the object being measured, and the need to directly replace the entire device when the sensor head is damaged or aged.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fluorescent fiber optic temperature measuring device, comprising a temperature measuring box, one end of an electric wire fixedly connected to the outer wall of the temperature measuring box, the other end of the electric wire fixedly connected to a display screen, one end of a detection line fixedly connected to the outer wall of the temperature measuring box, a fixed shaft fixedly connected inside the detection line, a spring piece fixedly connected to the outer wall of the fixed shaft, a sliding shaft fixedly connected to the outer wall of the spring piece, the outer wall of the sliding shaft slidably connected to the inside of the detection line, and a detection device provided on the outer wall of the detection line for detecting temperature.

[0006] The above technical solution involves connecting the display screen via wires, allowing users to visually view real-time temperature data, device connection status, and other information. A fixed shaft supports the spring sheet, and pressing the sliding shaft causes the spring sheet to sink and slide inside the detection line.

[0007] Preferably, the detection device includes an adapter, the interior of which is slidably connected to the outer wall of the detection line, the outer wall of the adapter has a hole, the outer wall of the sliding shaft is slidably connected to the inner wall of the hole, and a sensor head is fixedly connected to the outer wall of the adapter.

[0009] Preferably, the outer wall of the bidirectional lead screw is rotatably connected to the inside of the first support plate, and the outer wall of the bidirectional lead screw is threadedly connected to the first clamping plate.

[0010] Preferably, a receiving shaft is slidably connected inside the first clamping plate, and a second support plate is fixedly connected to the outer wall of the receiving shaft.

[0011] Preferably, the lower surface of the second support plate is fixedly connected to the upper surface of the temperature measuring box, and the upper surface of the temperature measuring box is fixedly connected to the first receiving plate.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the sensor head can be detached from the outer wall of the detection line by pulling the sensor head through the adapter, which allows for the replacement of the sensor head, enhancing adaptability. The sensor head can be flexibly replaced according to the object being measured without the need to repurchase the entire device. Furthermore, when the sensor head is damaged, there is no need to replace the entire device; the damaged or aged sensor head can be directly replaced, thereby improving the economy and practicality of the equipment.

[0016] 2. In this utility model, when the bidirectional lead screw rotates, it drives the threaded first clamping plate to slide on the outer wall of the receiving shaft. The first clamping plate slides on the surface of the first receiving plate, and the first receiving plate can fit into the surface of the required installation position, so that it can be directly clamped on the bracket, pipe, equipment frame and other parts, adapting to a variety of scenarios, achieving the effect of rapid deployment and reducing installation costs.

[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Example 1:

[0026] Reference Figures 1-3 An embodiment of this utility model provides a fluorescent fiber optic temperature measuring device, including a temperature measuring box 1. One end of a wire 2 is fixedly connected to the outer wall of the temperature measuring box 1, and the other end of the wire 2 is fixedly connected to a display screen 3. One end of a detection line 4 is fixedly connected to the outer wall of the temperature measuring box 1. A fixed shaft 5 is fixedly connected inside the detection line 4. A spring piece 6 is fixedly connected to the outer wall of the fixed shaft 5. A sliding shaft 7 is fixedly connected to the outer wall of the spring piece 6. The outer wall of the sliding shaft 7 is slidably connected inside the detection line 4. A detection device is provided on the outer wall of the detection line 4 for detecting temperature.

[0027] Specifically, the temperature measuring box 1 provides fixed support for the wire 2, and the display screen 3 provides fixed support for the wire 2. The display screen 3 is used to intuitively display the real-time measured temperature data, the device's operating status, and the device's connection status. The temperature measuring box 1 provides support and fixation for the detection line 4, and the detection line 4 provides support and fixation for the fixing shaft 5. The fixing shaft 5 fixes the spring piece 6, and the spring piece 6 fixes the sliding shaft 7. By pressing the sliding shaft 7, the elastic force of the spring piece 6 causes it to slide and sink inside the detection line 4. The detection line 4 provides support, sliding, and limiting for the sliding shaft 7. When the spring piece 6 sinks, the detection device can be replaced. Releasing the pressed sliding shaft 7 will cause the spring piece 6 to rebound and fix the detection device.

[0028] Reference Figures 1-3 The detection device includes an adapter 9, the inside of which is slidably connected to the outer wall of the detection line 4. The outer wall of the adapter 9 has a hole 8, the outer wall of the sliding shaft 7 is slidably connected to the inner wall of the hole 8, and the outer wall of the adapter 9 is fixedly connected to the sensor head 10.

[0029] Specifically, the outer wall of the adapter 9 has a hole 8. When the sliding shaft 7 sinks down, it can disengage from the inner wall of the hole 8, thereby loosening the fixation on the adapter 9. The sensor head 10 can be pulled through the adapter 9 to disengage from the outer wall of the detection line 4, allowing the sensor head 10 to be replaced. This enhances adaptability, allowing for flexible replacement of the appropriate sensor head 10 according to the object being measured, without the need to repurchase the entire device. Furthermore, when the sensor head 10 is damaged, there is no need to replace the entire device; only the damaged or aged sensor head 10 needs to be replaced. This improves the economy and practicality of the equipment and expands its application range.

[0030] Reference Figure 1 , Figure 4 and Figure 5 A first support plate 11 is fixedly connected to the upper surface of the temperature measuring box 1. A first motor 12 is fixedly connected to the outer wall of the first support plate 11. A bidirectional lead screw 13 is fixedly installed at the output end of the first motor 12. The outer wall of the bidirectional lead screw 13 is rotatably connected to the inside of the first support plate 11. A first clamping plate 14 is threadedly connected to the outer wall of the bidirectional lead screw 13. A receiving shaft 15 is slidably connected inside the first clamping plate 14. A second support plate 16 is fixedly connected to the outer wall of the receiving shaft 15. The lower surface of the second support plate 16 is fixedly connected to the upper surface of the temperature measuring box 1. A first receiving plate 17 is fixedly connected to the upper surface of the temperature measuring box 1. The lower surface of the first clamping plate 14 is slidably connected to the upper surface of the first receiving plate 17.

[0031] Specifically, the temperature measuring box 1 supports and fixes the first support plate 11, which in turn supports and fixes the first motor 12, ensuring the stability of the first motor 12 during operation. The temperature measuring box 1 fixes the second support plate 16, which in turn fixes the receiving shaft 15. When the first motor 12 starts, it drives the bidirectional lead screw 13 at the output end to rotate inside the first support plate 11. When the bidirectional lead screw 13 rotates, it drives the threaded first clamping plate 14 to move and clamp. The temperature measuring box 1 supports and fixes the first receiving plate 17, allowing the first clamping plate 14 to slide on the outer wall of the receiving shaft 15 as it moves. The receiving shaft 15 supports the sliding and limits the movement of the first clamping plate 14, ensuring that the first clamping plate 14 does not deviate when moving in a straight line. This allows it to be directly clamped onto brackets, pipes, equipment frames, etc., adapting to various scenarios. No additional fasteners are required, making installation convenient, saving space, achieving rapid deployment, and reducing installation costs.

[0032] Example 2:

[0033] Reference Figure 6 A second receiving plate 18 is fixedly connected to the upper surface of the temperature measuring box 1. A second motor 19 is fixedly connected inside the second receiving plate 18. A slot 22 is opened on the surface of the second receiving plate 18. A gear 20 is fixedly installed at the output end of the second motor 19. A rack 21 is meshed with the tooth end of the gear 20. A second clamping plate 23 is fixedly connected to the upper surface of the rack 21. The outer wall of the second clamping plate 23 is slidably connected to the inner wall of the slot 22.

[0034] Specifically, the temperature measuring box 1 supports and fixes the second motor 19, ensuring the stability of the second motor 19 during operation. When the second motor 19 starts, it drives the gear 20 at the output end to rotate, which in turn drives the rack 21, which is connected to the gear end, to move. The surface of the second receiving plate 18 has a slot 22. The rack 21 fixes the second clamping plate 23, and when the rack 21 moves, it drives the second clamping plate 23 to slide synchronously on the inner wall of the slot 22 for clamping. The slot 22 supports the sliding and limits the second clamping plate 23, so it can be directly clamped on brackets, pipes, equipment frames, etc., adapting to various scenarios. No additional fasteners are required, making installation convenient, saving space, achieving rapid deployment, and reducing installation costs.

[0035] Working principle: When the device is needed, the first motor 12 on the outer wall of the first support plate 11 is started to rotate the bidirectional lead screw 13 at the output end. The receiving shaft 15 is fixed by the second support plate 16. When the bidirectional lead screw 13 rotates, it drives the threaded first clamping plate 14 to slide on the outer wall of the receiving shaft 15. The first clamping plate 14 slides on the surface of the first receiving plate 17. The first receiving plate 17 can fit against the surface of the required installation position, so it can be directly clamped on brackets, pipes, equipment frames, etc. It is suitable for a variety of scenarios, requires no additional fasteners, is easy to install, saves space, achieves rapid deployment, and reduces installation costs.

[0036] Once the device is secured, start it. The real-time measured temperature data, device operating status, and connection information can be displayed on the screen 3 via the wire 2. Pressing the sliding shaft 7 causes the spring 6 to sink and disengage from the inner wall of the hole 8. Loosen the fixing of the adapter 9 and pull the sensor head 10 through the adapter 9 to detach from the outer wall of the detection line 4. The sensor head 10 can then be replaced, enhancing adaptability. The appropriate sensor head 10 can be flexibly replaced according to the object being measured without the need to repurchase the entire device. Furthermore, when the sensor head 10 is damaged, there is no need to replace the entire device; only the damaged or aged sensor head 10 needs to be replaced. This improves the economy and practicality of the device and expands its application range.
