[0002] In modern infrastructure construction and industrial production, the accompanying optical cable acoustic wave acquisition and positioning device plays a vital role. Whether it is the leakage monitoring of long-distance oil and gas pipelines or the health inspection of large structures such as railways and bridges, the device can promptly detect potential safety hazards and ensure the stable operation of facilities by accurately acquiring and locating acoustic waves.

[0003] Traditional acoustic wave acquisition and positioning devices for accompanying optical cables often use welding to fix the acquisition and positioning components to the optical cable. Welding not only requires professional welding equipment and technicians, but also makes it difficult to guarantee welding quality in complex outdoor environments. Once a poor weld or detachment occurs, the component will become loose, affecting the accuracy of acoustic wave acquisition and positioning. This makes the installation process cumbersome, and the complex installation process is prone to installation errors, further affecting the performance of the device. Therefore, we propose an acoustic wave acquisition and positioning device for accompanying optical cables. Utility Model Content

[0025] Please see Figure 1-4 This utility model provides a technical solution: a sound wave acquisition and positioning device for accompanying optical cables, comprising:

[0026] The optical cable body 1 and the support base 5 are provided. The top of the support base 5 is equipped with an information acquisition and processing computer 6. An installation sleeve 2 is fixedly sleeved on the outer surface of the optical cable body 1. A positioning structure 3 is provided on the installation sleeve 2.

[0027] The positioning structure 3 includes a first positioning arc plate 9, a second positioning arc plate 10, two first connectors 15, a second connector 14, and bolts 16. The second positioning arc plate 10 is hinged to the first positioning arc plate 9. Both first connectors 15 are fixedly connected to the first positioning arc plate 9. The second connector 14 is fixedly connected to the second positioning arc plate 10. The second connector 14 is inserted into the opposite surfaces of the two first connectors 15. The second connector 14 is fixedly installed between the two first connectors 15 by bolts 16. The first positioning arc plate 9 and the second positioning arc plate 10 are fixedly sleeved on the outer surface of the mounting sleeve 2 by bolts 16. The first positioning arc plate 9 has a mounting groove 12.

[0028] The positioning structure 3 also includes two anti-slip pads 11 and an acoustic wave acquisition probe 8. The two anti-slip pads 11 are fixedly connected inside the first positioning arc plate 9 and the second positioning arc plate 10, respectively. Both anti-slip pads 11 are made of rubber. The anti-slip pads 11 on the first positioning arc plate 9 have through holes 13. The acoustic wave acquisition probe 8 is installed inside the mounting groove 12. Two limiting rings 7 are fixedly sleeved on the outer surface of the mounting sleeve 2. The positioning structure 3 is located between the two limiting rings 7. There are multiple positioning structures 3, and the multiple positioning structures 3 are arranged in a linear array on the mounting sleeve 2.

[0029] A connecting cable 4 is connected to the information acquisition and processing computer 6. The end of the connecting cable 4 away from the information acquisition and processing computer 6 is installed inside the mounting sleeve 2. The connecting cable 4 is inserted inside the mounting sleeve 2 and connected to the sound wave acquisition probe 8.

[0030] The first positioning arc plate 9 and the second positioning arc plate 10 are both semi-circular arc structures. When the first positioning arc plate 9 and the second positioning arc plate 10 are closed, they form a complete ring.

[0031] Furthermore, when using this device, when external sound waves act on the accompanying optical cable, the optical cable body 1 will generate a slight vibration. The sound wave acquisition probe 8, installed on the positioning structure 3, is tightly close to the optical cable with the help of the first positioning arc plate 9 and the second positioning arc plate 10. The two rubber anti-slip pads 11 not only increase the friction between the positioning structure and the optical cable and prevent the positioning structure from sliding, but also better transmit the vibration of the optical cable to the sound wave acquisition probe 8. The sound wave acquisition probe 8 can accurately capture the vibration signal transmitted from the optical cable and convert it into an electrical signal. The converted electrical signal is transmitted through the connecting line 4 connected to the sound wave acquisition probe 8. One end of the connecting line 4 is installed inside the mounting sleeve 2 and connected to the sound wave acquisition probe 8, and the other end is connected to the acquisition information processing computer 6 on the top of the support base 5. The mounting sleeve 2 not only provides protection and wiring space for the connecting line 4, but also ensures the stability of signal transmission and power transmission and avoids external interference.

[0032] The data acquisition and processing computer 6 receives electrical signals from each sound wave acquisition probe 8 and analyzes and processes these signals using a built-in algorithm. Since multiple positioning structures 3 are arranged in a linear array on the mounting sleeve 2, the time and intensity of the sound waves received by the sound wave acquisition probes 8 at different positions are different. Based on these differences and combined with known parameters such as the spacing between the positioning structures 3, the data acquisition and processing computer 6 can accurately calculate the position of the sound wave source through a specific positioning algorithm, thereby achieving precise positioning of the sound wave source.

[0033] This device abandons the traditional welding method and adopts a positioning structure 3 that is hinged to the first positioning arc plate 9 and the second positioning arc plate 10 and fastened with bolts 16. During installation, it is only necessary to simply open the second positioning arc plate 10, put it on the installation sleeve 2, insert the second connector 14 and tighten the bolts 16. The whole process is simple to operate, without the need for professional welding equipment and technicians, which greatly simplifies the installation process, significantly shortens the installation time, and improves construction efficiency.
