[0023] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0024] Please refer to Figures 1 to 4 An optical fiber cable overheating online monitoring device comprises: an arc plate 2, wherein the number of the arc plates 2 is two, both ends of the two arc plates 2 are connected with arc air bags 6, and the two adjacent arc air bags 6 are connected to each other through a connecting pipe; an air channel is opened inside one of the arc plates 2, and the two arc air bags 6 located at the two ends of the arc plate 2 are connected to each other through the air channel;

[0025] One ends of the two arc-shaped plates 2 are rotatably connected, and the other ends of the two arc-shaped plates 2 are connected with a locking mechanism;

[0026] A monitoring device body 7, wherein the monitoring device body 7 is connected to one of the arc-shaped plates 2, and the monitoring device body 7 is arranged close to the center of the arc-shaped plate 2;

[0027] An inflation mechanism 1 is connected to one of the arc-shaped plates 2, and the inflation mechanism 1 includes a cylinder 12, the cylinder 12 is fixedly connected to the outer surface of one of the arc-shaped plates 2, and an elastic airbag 17 is connected inside the cylinder 12, and the elastic airbag 17 is interconnected with one of the arc-shaped airbags 6 through an air guide tube 15; the cylinder 12 is connected to a threaded extrusion component for extruding the elastic airbag 17, and an air vent 16 is provided at one end of the cylinder 12 away from its opening.

[0028] It should be noted that the monitoring device body 7 is used to monitor the overheating of the optical fiber cable. The FBG sensor inside the monitoring device body 7 detects the temperature change of the cable surface in real time. The temperature data collected by the sensor is transmitted to the data collector through the optical fiber. The data collector converts the optical signal into an electrical signal and performs preliminary processing, such as signal amplification and filtering, to ensure the clarity and accuracy of the signal. The data collector transmits the processed signal to the monitoring center (this is a prior art and will not be elaborated here). In addition, the optical fiber cable is passed through between the two arc plates 2 by rotating the arc plate 2, and then the elastic airbag 17 is squeezed by the threaded extrusion assembly, so that the gas in the elastic airbag 17 enters the arc airbag 6, and the gap between the optical fiber cable and the end of the arc plate 2 is sealed by the arc airbag 6, so that the monitoring device body 7 is in a relatively sealed environment, thereby improving the detection accuracy of the monitoring device body 7;

[0029] It is also necessary to explain that when the arc-shaped airbag 6 seals the gap between the optical fiber cable and the end of the arc-shaped plate 2, the arc-shaped plate 2 and the monitoring device body 7 can be stably connected to the optical fiber cable without the aid of external components. The installation of the monitoring device body 7 can be conveniently and quickly achieved, reducing the difficulty of using the device.

[0030] It is also necessary to explain that by adjusting the expansion degree of the arc-shaped airbag 6, optical fiber cables of different sizes can be monitored within a certain range, thereby improving the flexibility of the device.

[0031] refer to Figure 2 As shown, the elastic airbag 17 and the plurality of arc-shaped airbags 6 are filled with an inert gas having a density lower than that of air.

[0032] It should be noted that the inert gas can be helium, and the density of helium is less than that of air, so that the elastic airbag 17 and the plurality of arc-shaped airbags 6 both generate buoyancy, thereby offsetting part of their own gravity, reducing the downward pulling of the optical fiber cable when the entire device is in use, and reducing the impact on the use of the optical fiber cable;

[0033] It is also necessary to explain that the inert gas is always in the elastic airbag 17 and the multiple arc-shaped airbags 6, and the amount of the inert gas will not be adjusted, and the size of the buoyancy generated will not be adjusted, thereby increasing the stability of the device.

[0034] refer to Figure 2 As shown, the threaded extrusion assembly includes a fixed bracket 18, which is fixedly connected to the opening of the cylinder 12, and the fixed bracket 18 is threadedly connected to a threaded rod 14 that passes through it, and one end of the threaded rod 14 is rotatably connected to a movable plate 13; the movable plate 13 is slidably connected in the cylinder 12, and the movable plate 13 is connected to one end of the elastic airbag 17.

[0035] It should be noted that the movable plate 13 can be driven to move in the cylinder 12 by rotating the threaded rod 14 , and the elastic airbag 17 can be squeezed and released by the movable plate 13 , thereby adjusting the expansion degree of the arc-shaped airbag 6 .

[0036] refer to Figure 2 As shown, a handle 19 is further included. The handle 19 is fixedly connected to one end of the threaded rod 14 away from the movable plate 13 , and an anti-slip pad is fixedly connected to the outer surface of the handle 19 .

[0037] It should be noted that the handle 19 and the anti-slip pad facilitate the operator to rotate the threaded rod 14 .

[0038] refer to Figure 2 As shown, it also includes an air nozzle 11, which is fixedly connected to the outer surface of the cylinder 12 away from its opening, and the air nozzle 11 is connected to the elastic airbag 17.

[0039] It should be noted that the air nozzle 11 is used to facilitate inflation and deflation of the elastic airbag 17 .

[0040] refer to Figure 3 and Figure 4 As shown, the end of the arc-shaped airbag 6 is connected to an extension piece 8 which is interconnected therewith, and the thickness of the extension piece 8 is smaller than the thickness of the arc-shaped airbag 6 .

[0041] It should be noted that the extension piece 8 is located at the end of the arc-shaped airbag 6. The extension piece 8 can block the gap between two adjacent arc-shaped airbags 6, so that the monitoring device body 7 can work in an environment with better sealing conditions, thereby improving the accuracy of the monitoring device body 7.

[0042] refer to Figure 1 As shown, the locking mechanism includes two end plates 3 , and the two end plates 3 are fixedly connected to the ends of the two arc-shaped plates 2 respectively, and the two end plates 3 are locked by fastening bolts 5 .

[0043] It should be noted that the two end plates 3 are locked by tightening the bolts 5 , and the two end plates 3 can be separated by loosening the bolts 5 , which is beneficial for the optical fiber cable to pass through between the two arc-shaped plates 2 .

[0044] refer to Figure 1 As shown, a sealing gasket 4 is fixedly connected to the surface of one of the end plates 3 .

[0045] It should be noted that the sealing effect between the two end plates 3 is increased by the sealing gasket 4 .
