[0003] Existing methods for detecting fiber optic dancing mostly analyze the stress conditions of the fiber optic cable, but most of them are single-direction detection. However, when the optical fiber dances due to wind or other factors, its force directions are often multiple. Single-direction detection cannot accurately judge the dancing conditions of the fiber optic cable.

[0008] A further solution of the utility model is that the inner surfaces of the two shells are both provided with a card slot.

[0010] A further solution of the utility model is that the outer surfaces of the two clamping sleeves are clamped with second pressure sensing plates, and the outer surfaces of the two second pressure sensing plates are fixedly connected to the inner surface of the clamping slot.

[0011] A further solution of the utility model is that two clamping rings are clamped on the outer surfaces of the two shells.

[0012] The technical effect achieved by adopting the above solution is that the shell can be fixed on the surface of the cable.

[0013] A further solution of the utility model is that the outer surfaces of the four clamping rings are fixedly connected with four fastening bolts.

[0014] A further solution of the utility model is that the outer surfaces of the two shells are fixedly connected with a controller.

[0015] The technical effect achieved by adopting the above solution is that the pressure data of the first pressure sensing plate and the second pressure sensing plate can be transmitted to the back-end device in real time.

DETAILED DESCRIPTION

[0025] like Figures 1 to 3 As shown, a fiber optic cable dancing detection device comprises a shell 1, two outer surfaces of the two shells 1 are fixedly connected to two telescopic columns 2, the outer surfaces of the two shells 1 are provided with swing grooves 3, the inner surfaces of the two shells 1 are clamped with optical fiber cables 4, the outer surfaces of the optical fiber cables 4 are fixedly connected to two fixing sleeves 5, the outer surfaces of the two fixing sleeves 5 are fixedly connected to two swinging columns 6, one end of the four swinging columns 6 is fixedly connected to a first pressure sensing plate 7, the inner surfaces of the four telescopic columns 2 are provided with telescopic grooves 8, the outer surfaces of the four first pressure sensing plates 7 are fixedly connected to telescopic rods 9, one end of the four telescopic rods 9 is fixedly connected to the bottom of the telescopic grooves 8, and the outer surfaces of the four telescopic rods 9 are sleeved with Spring 10, one end of the four springs 10 is fixedly connected to the outer surface of the first pressure sensing plate 7, and the other end of the four springs 10 is fixedly connected to the outer surface of the telescopic slot 8. When the optical fiber cable 4 is swung by wind or other factors, the fixing sleeve 5 fixedly connected to the surface of the optical fiber cable 4 will also swing. The swing of the fixing sleeve 5 drives the two swinging columns 6 to swing. The swing of the two swinging columns 6 drives the first pressure sensing plate 7 to slide on the inner surface of the telescopic slot 8, thereby driving the telescopic rod 9 and the spring 10 to compress. When the swing amplitude is large, the swinging column 6 will drive the first pressure sensing plate 7 to contact the protruding position of the inner surface of the telescopic slot 8. After touching the bottom, the surface pressure of the first pressure sensing plate 7 increases instantly, and data is recorded.

[0026] The inner surfaces of the two housings 1 are both provided with a slot 11 .

[0027] The inner surfaces of the two card slots 11 are both clamped with card sleeves 12 , and the card sleeves 12 can be clamped into the card slots 11 .

[0028] The outer surfaces of the two ferrules 12 are both clamped with second pressure sensing plates 13, and the outer surfaces of the two second pressure sensing plates 13 are fixedly connected to the inner surface of the card slot 11. When the optical fiber cable 4 swings, a certain lateral drag force will inevitably be generated. Under the action of the force, the ferrule 11 fixedly connected to the optical fiber cable 4 will contact the second pressure sensing plate 13, and the sensing data will be recorded in real time.

[0029] Two clamping rings 14 are clamped on the outer surfaces of the two shells 1 , and the clamping rings 14 can fix the shells 1 to the surface of the optical fiber cable 4 .

[0030] Four fastening bolts 15 are fixedly connected to the outer surfaces of the four clamping rings 14 .

[0031] The outer surfaces of the two shells 1 are fixedly connected with a controller 16 , and the controller 16 transmits the pressure data of the first pressure sensing plate 7 and the second pressure sensing plate 13 to the back-end device in real time.

[0032] An optical fiber cable dancing detection device, the working principle is as follows: first, the device is sleeved on both ends of the optical fiber cable 4, and then the housing 1 is fixedly connected to the surface of the optical fiber cable 4 through the clamping ring 14. When the optical fiber cable 4 is swung by wind or other factors, the fixed sleeve 5 fixedly connected to the surface of the optical fiber cable 4 will also swing, and the swing of the fixed sleeve 5 drives the two swinging columns 6 to swing, and the swing of the two swinging columns 6 drives the first pressure sensing plate 7 to slide on the inner surface of the telescopic groove 8, thereby driving the telescopic rod 9 and the spring 10 to compress. When the swing amplitude is large, the swinging column 6 will drive the first pressure sensing plate 7 to contact the protruding position of the inner surface of the telescopic groove 8. After touching the bottom, the surface pressure of the first pressure sensing plate 7 increases instantly, and then the data is transmitted to the controller 16. When the optical fiber cable 4 swings, a certain lateral drag force will inevitably be generated. Under the action of the force, the clamping sleeve 11 fixedly connected to the optical fiber cable 4 will contact the second pressure sensing plate 13, and the sensing data will be transmitted to the controller 16 in real time. Then the controller 16 will transmit the pressure data of the first pressure sensing plate 7 and the second pressure sensing plate 13 to the back-end device in real time.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] 1. The first pressure sensing plate 7 and the second pressure sensing plate 13 of the device can monitor the dancing amplitude and dragging force of the optical fiber cable 4 respectively. The two different monitoring methods can make the monitoring data more accurate.

[0035] 2. The design of two clamping rings 14 at each end of the device can make the housing 1 more firmly fixed on the surface of the optical fiber cable 4, which is convenient for installation and has a simple structure.
