[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Example: See Figure 1-4This utility model discloses a fiber optic cable temperature measurement device for fire early warning, comprising a main box 1. A display screen 5 is embedded on one side of the main box 1, which facilitates quick understanding of the device's working status, timely detection of abnormal temperature changes, and corresponding measures. Multiple control interfaces for connecting to external systems are provided on the bottom of the other side of the main box 1. A cable 2 is provided on one of the control interfaces, which facilitates the real-time transmission of collected temperature data back to the data processing unit inside the main box 1 for analysis and processing. A detection block 3 is provided at the other end of the cable 2, which can be tightly attached to the surface of the fiber optic cable to accurately detect minute temperature changes along the cable. A placement slot 9 for storing the detection block 3 is provided in the middle of the other side of the main box 1, providing a dedicated storage area for the detection block 3, ensuring proper protection and management when not in operation. Ventilation openings 4 are provided at both ends of the main box 1, and a cable laying chamber is provided at one end of the main box 1. The cable laying chamber has a storage door 6, which effectively protects the cables 2 and components inside the cable laying chamber.

[0019] In this invention, an abutment interface is provided on the inner wall of the placement groove 9, and an abutment block 8 is provided inside the abutment interface. A rotating shaft is provided on the abutment block 8, one end of which is connected to one side of the main box 1, and a hand-tightening nut 7 is fixed to the other end of the rotating shaft. The abutment block 8 provides a stable fixing effect for the detection block 3, ensuring the safety and stability of the detection block 3 during storage. Two support shafts 10 are provided on one end face of the main box 1, and magnetic suction blocks 11 are rotatably provided on both support shafts 10. A fixing cap is provided on one side of the magnetic suction blocks 11, which provides a simple and convenient... Furthermore, the storage door 6 is reliably fixed; the storage door 6 is equipped with two magnetic blocks 12 that respectively cooperate with the magnetic block 11; the storage door 6 has an embedded groove in the middle, and a handle 13 is provided in the embedded groove, which improves the efficiency and convenience of the operator in opening and closing the storage door 6; the placement groove 9 is equipped with a buffer pad for protecting the detection block 3, which helps to prevent the detection block 3 from being bumped during storage; four grooves are provided on one side of the main box 1, and bolts for fixing are provided in the four grooves, which facilitates the fixing of the device.

[0020] Working Principle: In normal operation, the detection block 3 is connected to the main housing 1 via cable 2 and receives power. The high-precision temperature sensor array inside the detection block 3 is tightly attached to the surface of the optical cable. Due to the thermal conduction effect, the temperature change of the optical cable is quickly transmitted to the temperature sensors. These sensors, based on the thermoelectric effect or other temperature measurement principles, convert the sensed temperature information into corresponding electrical signals. The converted electrical signals are transmitted to the data processing unit inside the main housing 1 via cable 2. At the same time, the current temperature information and the system's operating status are displayed on the display screen 5 on one side of the main housing 1 for operators to check at any time. After use, when the detection block 3 needs to be stored, it is placed in the placement slot 9 and the screw is turned by rotating the hand screw. The mother 7 drives the abutment block 8 to rotate, causing the abutment block 8 to press the detection block 3, thereby fixing and protecting the detection block 3 and preventing it from being damaged due to shaking or collision. In the relevant operations of the cable laying chamber, the magnetic block 12 on the storage door 6 cooperates with the magnetic stop block 11 on one end face of the main box 1. When the storage door 6 is closed, the magnetic stop block 11 is attracted together with the magnetic block 12 under the rotation of the support shaft 10, which firmly fixes the storage door 6 and prevents dust and other impurities from entering the cable laying chamber and affecting the cable 2 and related components. When it is necessary to open the storage door 6 for cable laying or maintenance operations, the operator holds the handle 13 and rotates the magnetic stop block 11 to separate it from the magnetic block 12, so that the storage door 6 can be opened smoothly. This concludes the use of a fiber optic cable temperature measuring device for fire early warning.

[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
