[0002] Distributed optical fiber technology is an advanced sensing technology based on the transmission characteristics of light in optical fiber, used to monitor the changes of environmental parameters along the optical fiber path. By analyzing the changes of optical signals propagating in the optical fiber, such as optical time domain reflection, Brillouin scattering, Raman scattering or phase-sensitive optical time domain reflection, distributed optical fiber can achieve high-precision measurement of multiple physical quantities such as temperature, strain and vibration, and can provide spatial distribution information along the entire optical fiber length.

[0023] When the distributed optical fiber monitoring system is implemented in the soft soil subgrade, in order to ensure the stability and reliability of optical fiber transmission, the installation box 5 is usually used to protect the monitor 7. First, the installation box 5 needs to be fixed firmly on the selected plane position, and then the monitor 7 is arranged in the installation box 5, so that the real-time monitoring of the optical fiber state is realized. However, when the installation box 5 is arranged in the outdoor environment, the challenge brought by weather change cannot be avoided, especially the rain may cause the rainwater to enter the installation box 5 through the heat dissipation hole, and then damage the internal monitor 7. Therefore, the collecting box 101 is arranged on the top of the installation box 5. When it rains, the rainwater is captured by the collecting plate and accumulated in the collecting box 101. With the increase of water volume, the weight of the collecting box 101 increases, so that the telescopic rod 3 below the collecting box 101 is compressed. This process promotes the collecting box 101 to gradually move downward, and drives the L-shaped plate 102 connected therewith to synchronously descend. The L-shaped plate 102 further drives the protective plate 103 located below the L-shaped plate 102 to slide in the supporting box 104 until the protective plate 103 contacts the limiting plate 106. In this way, the heat dissipation hole on the filter plate 4 is closed, and the partition plate 105 in the supporting box 104 divides the supporting box 104 into two independent areas, so that a sealed space can be formed when the protective plate 103 is closed, and the rainwater is effectively prevented from entering the installation box 5. After the rain stops, the rainwater in the collecting box 101 evaporates gradually under the sunlight, the weight of the collecting box 101 decreases, the telescopic rod 3 gradually restores to the original state, and the protective plate 103 is reset to reopen the filter plate 4 to maintain the normal heat dissipation function of the installation box 5. In addition, considering that dust may accumulate on the surface of the filter plate 4 during long-term use, the heat dissipation efficiency is affected, and therefore the filter plate 4 needs to be cleaned regularly. The specific method is to pull the fixed plate 205, drive the brush plate 201 to slide along the surface of the filter plate 4 through the connecting rods 202 on both sides, and clean the filter plate 4. At the same time, since the elastic block 203 is arranged in the installation sleeve 204, the brush plate 201 can be automatically reset after cleaning, so that the filter plate 4 can work continuously and efficiently. In this way, the service life of the equipment is improved, and the reliable operation of the whole monitor 7 is ensured.
