Technical Field

[0001] The utility model belongs to the technical field of optical fiber temperature measurement, and more specifically, relates to a fluorescent optical fiber temperature measurement device for a fire protection system. Background Art

[0002] Fire alarm systems are required for both fire protection and security system construction. Traditional fire alarm systems primarily rely on smoke detectors for fire warnings. Smoke detectors, also known as smoke fire detectors, smoke detectors, smoke probes, and smoke sensors, primarily monitor smoke concentration to prevent fires. Smoke sensors utilize ionization smoke sensors, a technologically advanced, stable, and reliable sensor widely used in various fire alarm systems, far outperforming gas-sensitive resistor-based fire alarms. However, existing smoke detectors suffer from issues such as insensitivity to smoke concentration, slow temperature measurement, and slow response to incipient fires. Furthermore, once installed, smoke detectors are relatively fixed in position and cannot be adjusted locally, making them inconvenient for temperature measurement at multiple locations.

[0003] Therefore, it is necessary to design a temperature measuring device for fire alarm that can quickly detect smoke concentration, has high temperature measurement sensitivity, and responds quickly to initial fires to meet the needs of the fire protection system. Utility Model Content

[0029] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0030] Please also refer to Figures 1 to 4 Now, a fluorescent optical fiber temperature measuring device for a fire protection system provided by the present invention is described. The fluorescent fiber optic temperature measuring device for a fire protection system includes a base 1, a slide rail 2, a box body 3, a fluorescent fiber optic temperature measuring probe 4, a control system 5 and a battery 6. The base 1 is used to be connected to the wall of a fire protection project; the slide rail 2 is rotatably connected to the base 1 at the middle position along its length direction, and the slide rail 2 has the freedom of circumferential rotation around the rotation connection between it and the base 1, and the position of the slide rail 2 after rotation can be locked; a slider is connected to the bottom of the box body 3, and the slider is slidably connected to the slide rail 2, and the slider has the freedom of sliding along the length direction of the slide rail 2; the fluorescent fiber optic temperature measuring probe 4 is connected to the box body 3 and is used for temperature measurement in a fire protection system. The fluorescent fiber optic temperature measuring probe 4 has the freedom of sliding along the length direction of the slide rail 2 with the help of the sliding of the box body 3, and is used to adjust the temperature measuring position of the fluorescent fiber optic temperature measuring probe 4 after sliding; the control system 5 is communicatively connected to the fluorescent fiber optic temperature measuring probe 4 and is used to receive and display the temperature information collected by the fluorescent fiber optic temperature measuring probe 4; the battery 6 is connected to the box body 3, electrically connected to the fluorescent fiber optic temperature measuring probe 4 and used for power supply.

[0031] The present invention provides a fluorescent fiber optic temperature measuring device for a fire protection system. Compared with the prior art, a base 1 is installed on the wall, and a slide rail 2 is provided on the base 1, which can be rotated and adjusted and facilitates the sliding adjustment of a box body 3, so that the fluorescent fiber optic temperature measuring probe 4 can measure temperature at multiple positions, which is convenient for measuring temperature at multiple temperature measuring points of a fire protection project, so as to monitor in real time whether the fire protection system is in the early stage of a fire and provide timely warnings, solving the technical problems of smoke detectors in the fire protection system being insensitive, slow in temperature measurement speed, and inconvenient in measuring temperature at multiple positions. The utility model has the technical effects of being able to be used in a fire protection system, having a fast temperature measurement speed, and being able to measure temperature at multiple positions.

[0032] The control system 5 in this embodiment is a conventional control system, including a fiber optic temperature transmitter, a display screen, a PLC controller, a signal receiver, a wireless communicator, and the like. The fluorescent fiber optic temperature probe 4 is connected to the fiber optic temperature transmitter via an optical fiber. The information collected by the fluorescent fiber optic temperature probe 4 is transmitted to the fiber optic temperature transmitter in real time and displayed on the display screen. Workers can view the current temperature of the fire protection system by observing the display screen. The control system 5 can be installed in an office or other convenient location where workers can see temperature information, while the fluorescent fiber optic temperature probe 4 is installed in the fire protection system project. The fluorescent fiber optic temperature probe 4 is a conventional fiber optic probe or temperature-sensing fiber for measuring temperature, capable of rapid temperature measurement and a fast response speed. The fluorescent fiber optic temperature probe 4 can be installed inside the box body 3, with the end used for measuring temperature exposed or extending outside the box body 3 to measure the temperature.

[0033] Preferably, a top screw 7 is obliquely provided on the side of the box body 3, and the inner end of the top screw 7 can abut against the slide rail 2. When the top screw 7 abuts against the slide rail 2, the position of the box body 3 can be limited, that is, the box body 3 is locked. When the top screw 7 is screwed in the opposite direction, the inner end of the top screw 7 moves away from the slide rail 2, and the limit on the box body 3 can be released. In this embodiment, the top screw 7 can be a component such as a screw. A plurality of blind holes 8 can also be provided on the slide rail 2 along the length direction of the slide rail 2. The inner end of the top screw 7 can be correspondingly inserted into the blind hole 8 at a certain position, so that the position of the top screw 7 can be locked. The box body 3 and the current position of the fluorescent fiber optic temperature measuring probe 4 are then locked.

[0034] In some embodiments, see Figures 1 to 4, a plurality of mounting holes 9 are provided on the base 1, and fasteners 10 are passed through the mounting holes 9. The fasteners 10 are used to fix and connect to the wall of the fire protection project. The base 1 is a rectangular structure, and its thickness is much smaller than its length and width. It can be regarded as a plate-like structure. In this embodiment, there are four mounting holes 9. In actual operation, the number of mounting holes 9 can be reasonably set according to the length of the base 1 to achieve a uniform distribution. In this way, the base 1 can be firmly and stably connected to the wall. The base 1 can be fixed on a wall that is set in a vertical shape, or on a wall that is set in a horizontal shape (i.e., on the ceiling), and the slide rail 2 is always on the side facing away from the wall. In this embodiment, the number of mounting holes 9 is four, all of which are fixed to the wall by fasteners 10 (such as bolts, expansion bolts, etc.). The length direction of the fastener 10 is perpendicular to the length direction of the base 1.

[0035] Since the wall is flat, in order to increase the contact area between the base 1 and the wall and improve the stability of the base 1 after connection, in some embodiments, refer to Figure 1 and Figure 3 The base 1 includes a bottom plate 11 and a top plate 12, both of which are plate-shaped. The bottom plate 11 and the top plate 12 are adapted to be fixedly connected to each other. The slide rail 2 is installed on the top plate 12. The bottom plate 11 is used to be placed against the wall of the fire protection project. The plane formed by the rotation of the slide rail 2 is parallel to the plane of the top plate 12 or the bottom plate 11. The specifications of the bottom plate 11 are the same as those of the top plate 12. The two can be fully adapted and corresponding to form a whole. The thickness of the two can be reasonably selected according to the actual installation situation. The bottom plate 11 and the top plate 12 can be bonded together by adhesive or the like.

[0036] As a preference, see Figure 3 Both the bottom plate 11 and the top plate 12 are formed by splicing together multiple small plates 13. Adjacent small plates 13 are locked and fixed to each other by latches. The multiple small plates 13 are connected and assembled to form a single plate body, namely the bottom plate 11 or the top plate 12. The small plates of the bottom plate 11 and the top plate 12 are of the same size or specification and are placed overlapping. In this embodiment, there are three small plates 13. The mounting holes 9 are provided on the small plates 13. After the multiple small plates 13 are connected, the slide rail 2 is installed.

[0037] To prevent heat from the wall from being transferred to the box body 3 and thereby affecting the operation of the fluorescent fiber optic temperature probe 4, in some embodiments, the bottom plate 11 is a heat-insulating plate. This isolates or cuts off the heat from the wall and the box body 3 or the slide rail 2, allowing the fluorescent fiber optic temperature probe 4 to always measure the temperature in the air. This also prevents cold air from the wall from being transferred to the box body 3 or the slide rail 2.

[0038] In some embodiments, see Figure 1 and Figure 3The length of the slide rail 2 is smaller than that of the base 1. A rotating table is provided in the middle of the slide rail 2. One end of the rotating table is fixedly connected to the base 1, and the other end has circumferential rotational freedom and is used to connect to the middle position of the slide rail 2. The slide rail 2 rotates circumferentially with the help of the rotating table. By rotating the slide rail 2 by the rotating table, the temperature measuring position of the fluorescent fiber optic temperature measuring probe 4 can be adjusted, that is, the moving trajectory of the fluorescent fiber optic temperature measuring probe 4 is circular. At this time, the rotation of the fluorescent fiber optic temperature measuring probe 4 can be regarded as "revolution". By controlling the forward and reverse rotation or rotation angle of the rotating table, the moving position of the fluorescent fiber optic temperature measuring probe 4 can be controlled. Limit blocks are provided at both ends of the slide rail 2 to prevent the slider from slipping off the slide rail 2.

[0039] In some embodiments, see Figure 1 and Figure 3 The rotating platform is a first electric rotating platform 14 and is electrically connected to a battery 6. The battery 6 is used to supply power to the first electric rotating platform 14. The battery 6 can be charged and discharged, and the power output end is connected to the rotating platform and can supply power. By using the battery 6, it is not necessary to connect to the mains, which is convenient to use.

[0040] In some embodiments, see Figure 1 and Figure 3 The first electric rotating platform 14 is communicatively connected to the control system 5. The control system 5 includes control buttons for controlling the rotation of the first electric rotating platform 14. By manipulating the control buttons, the rotation of the first electric rotating platform 14 is controlled, thereby adjusting the temperature measurement position of the fluorescent fiber temperature measurement probe 4. The first electric rotating platform 14 and the control system 5 can be connected via a wiring harness. The rotation of the first electric rotating platform 14 can be controlled by manipulating the control buttons, making operation more convenient.

[0041] In some embodiments, see Figure 1 and Figure 3 , the slider is connected to a second electric rotary table 15, one end of the second electric rotary table 15 is connected to the slider and the other end is connected to the box body 3. The box body 3 has circumferential rotation freedom with the help of the second electric rotary table 15. The rotation plane of the second electric rotary table 15 is arranged parallel to the rotation plane of the first electric rotary table 14. The first electric rotary table 14 and the second electric rotary table 15 are both existing technology products, which can realize circumferential rotation. The rotation can be controlled separately by operating on the control system 5, and then the temperature measuring position of the fluorescent fiber optic temperature measuring probe 4 can be reasonably adjusted. In this embodiment, the volume of the second electric rotary table 15 is smaller than that of the first electric rotary table 14. Figure 3 In the middle view, the upper end of the second electric rotating platform 15 is connected to the bottom end of the box body 3, and an opening is set on the side of the box body 3. The fluorescent fiber optic temperature measuring probe 4 can extend out of the opening and be exposed.

[0042] In some embodiments, see Figure 1 and Figure 3The second electric rotating platform 15 is communicatively connected to the control system 5, and its rotation is controlled by the control system 5. The control system 5 is also provided with a control button for controlling the rotation of the second electric rotating platform 15. By manipulating the control button, the rotation of the fluorescent fiber optic temperature measuring probe 4 can be controlled, that is, the orientation of the fluorescent fiber optic temperature measuring probe 4 can be adjusted. In this case, the rotation of the fluorescent fiber optic temperature measuring probe 4 can be considered as "autorotation." In the present utility model, the rotation of the first electric rotating platform 14, the sliding of the slider, and the rotation of the second electric rotating platform 15 are coordinated to enable the fluorescent fiber optic temperature measuring probe 4 to measure temperature at multiple locations, thereby measuring over the widest possible range, controlling the temperature of the fire protection system, and providing a temperature reference for fire alarms.

[0043] When the wall is an iron wall, it is not convenient to drill holes and install the fastener 10. In some embodiments, refer to Figures 3 and 4 The end of the fastener 10 near the wall is detachably connected to a magnetic plate 16, which is used to magnetically attract iron walls. By making the magnetic plate 16 magnetically attract the iron wall, operations such as drilling can be avoided, and the magnetic plate 16 can be directly magnetically attached to the iron wall. At this time, the base 1 can be firmly and stably fixed to the wall. The magnetic attraction between the magnetic plate 16 and the wall is equivalent to the mutual attraction between two magnets or the mutual attraction between a magnet and an iron object. Specifically, the end of the fastener 10 can be threadedly connected to the magnetic plate 16.

[0044] In the present invention, the fluorescent powder within the fluorescent fiber optic temperature probe 4 can be excited, and at different temperatures, the fluorescent powder will emit different light signals back to the control system 5. The emitted light signal is then demodulated into an electrical signal, outputting a specific temperature value, completing the temperature measurement step. The fluorescent fiber optic temperature probe 4 has the advantages of intrinsic safety, resistance to strong electromagnetic interference, good electrical insulation, high precision, stable performance, long life, corrosion resistance, and small size. It has unique technical advantages in the field of industrial temperature measurement under special environments such as high voltage and strong electromagnetic interference. At the same time, it can complete multi-point temperature monitoring of complex topological structures and has extremely high environmental adaptability. It can be widely used in various industrial environments and research fields such as power generation, power transmission, aerospace, industrial microwave, medical treatment, food processing, petrochemical industry, plastics and rubber industry, microwave chemistry, etc.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
