[0024] In order to help those skilled in the art better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the specification of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0025] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0026] See also Figures 1-4 The utility model provides a cable temperature measurement and alarm device, comprising: a connecting mechanism 1, a fixing mechanism 2 connected to the connecting mechanism 1, and a monitoring mechanism 3 connected to the fixing mechanism 2.

[0027] In some embodiments, the connecting mechanism 1 is a part that connects the optical fiber temperature measurement alarm device to other components for fixing, including: a connecting seat 11, a connecting plate 12 connected to the connecting seat 11, a threaded rod 13 threadedly connected to the connecting plate 12, and a handle 14 and a pressure block 15 respectively provided at both ends of the threaded rod 13; in some embodiments, the connecting seat 11 is an L-shaped structure, and a fixing hole 111 is provided on one vertical end thereof. The optical fiber temperature measurement alarm device can be fixed to the wall by passing a screw through the fixing hole 111 and then connecting it to a wall, etc.

[0028] In some more preferred embodiments, the connecting plate 12 is also L-shaped, with one end of the connecting plate 12 vertically connected to one end of the connecting seat 11 vertically disposed, and the pressing block 15 is disposed at one end of the threaded rod 13 close to the connecting seat 11. The pressing block 15 is adapted to the connecting seat 11, and is used to fix the connecting mechanism 1 by adjusting the distance between the pressing block 15 and the connecting seat 11. Specifically, the operator can adjust the distance between the pressing block 15 and the connecting seat 11 by rotating the handle 14, thereby clamping the connecting mechanism 1 and the fixing components such as the hanging plate, thereby fixing the optical fiber temperature measurement alarm device. The operator can select the above fixing method according to the actual scenario, thereby enhancing the flexibility and practicality of the optical fiber temperature measurement alarm device.

[0029] In some embodiments, the fixing mechanism 2 is a part for fixing the monitoring mechanism 3, which includes: a connecting column 21, a sliding sleeve 22 slidingly connected to the connecting column 21, a fixing bolt 23 connected to the sliding sleeve 22, a first arm 24 connected to the sliding sleeve 22, a second arm 25 rotatably connected to the first arm 24, a third arm 26 rotatably connected to the second arm 25, and a fixing plate 27 rotatably connected to the third arm 26; in some embodiments, one end of the connecting column 21 is connected to one end of the connecting seat 11 horizontally arranged, and the position of the sliding sleeve 22 is adjusted by sliding the sliding sleeve 22 on the connecting column 21, thereby adjusting the position of the monitoring mechanism 3, and the fixing bolt 23 is threadedly connected to the sliding sleeve 22, and the sliding sleeve 22 can be fixed to the connecting column 21 by adjusting the tightness between the fixing bolt 23 and the connecting column 21.

[0030] Furthermore, by rotatably connecting the two ends of the second arm 25 to the first arm 24 and the third arm 26 respectively, the fixing plate 27 is also connected to the monitoring mechanism 3, so that the operator can move the monitoring mechanism 3 at multiple angles, so that the operator can observe the monitoring mechanism 3 in real time.

[0031] In some embodiments, the monitoring mechanism 3 is a portion for monitoring the temperature of an optical fiber, and includes: a temperature-sensitive optical fiber 31, a distributed optical fiber temperature detector 32 connected to the temperature-sensitive optical fiber 31, and a display screen 33 and a buzzer 34 in communication with the distributed optical fiber temperature detector 32. In some embodiments, the temperature-sensitive optical fiber 31 can be laid near or in direct contact with the cable, and the optical fiber interface of the distributed optical fiber temperature detector 32 is connected to one end of the temperature-sensitive optical fiber 31. The distributed optical fiber temperature detector 32 can detect temperature changes at different positions along the optical fiber based on OTDR technology and the temperature-sensitive property of Raman scattered light, thereby obtaining the temperature of each point along the temperature-sensitive optical fiber 31, and further obtaining the temperature of each point along the cable laid near or in contact with the temperature-sensitive optical fiber 31.

[0032] Specifically, the distributed fiber optic temperature sensor 32 emits laser pulses into the temperature-sensing fiber 31. The molecules in the temperature-sensing fiber 31 interact with the laser pulses, generating Raman scattered light, including anti-Stokes and Stokes light. The intensity of anti-Stokes light is very sensitive to temperature changes, while the intensity of Stokes light is relatively stable. By measuring the intensity ratio of these two types of light, the system can calculate the temperature at each point along the fiber. Furthermore, as the pulsed light signal propagates through the fiber, it interacts with the molecules there, generating scattered light. By measuring the time it takes for the scattered light to return, the temperature change can be precisely located.

[0033] Furthermore, the display screen 33 can be connected to the distributed optical fiber temperature meter 32 via a switch. The display screen 33 is used to display temperature data along the optical fiber. Exemplary temperature data can be a temperature curve. The buzzer 34 is used to emit a sound alarm signal when the optical fiber temperature is abnormal to alert the operator.

[0034] Finally, it should be noted that the embodiments disclosed in the present invention are only preferred embodiments of the present invention, which are only used to illustrate the technical solutions of the present invention, rather than to limit them. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features therein can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
