Embodiment Construction
[0036] As can be seen from the accompanying drawings, a simulation device for monitoring dam seepage based on distributed optical fiber sensing mainly includes an optical fiber sensing demodulation unit 1 and a dam seepage simulation and control unit 4. The optical fiber sensing demodulation unit 1 consists of a sensor Composed of optical cable 11, optical fiber demodulation system 12, optical cable reel 13, sensing optical cable connector 14, and terminal box 15, the sensing optical cable 11 is pre-buried in the dam model medium in the box body 3, and the sensing optical cable 11 is fixed by the optical cable fixing device 2 In the U-shaped groove on the two side walls of the box body 3, the optical cable fixing device is arranged on the lower part of the outer wall of the box body 3 of the U-shaped groove. The optical cable fixing device 2 includes a jacket 21 and a support plate 22 for fixing the sensing optical cable 11. The support plate 22 is provided with a limit groove ...
