A circular block 706 is fixedly connected to the lower end of the sliding pin 704, and a spring 707 is sleeved on the surface of the sliding pin 704. Both ends of the spring 707 are fixedly connected to the fixed block 705 and the circular block 706 respectively.

At this time, the trough and the baffle 702 will move downward due to the gravity of the rainwater, and the connecting frame 710 will move downward with the collecting trough 701. The sponge bar 711 on the connecting frame 710 will move relative to the prism 6, thereby facilitating the wiping of the prism 6.

At this time, the trough and the baffle 702 will move downward under the action of the gravity of the rainwater, and the connecting frame 710 will move downward with the collecting trough 701. The sponge strip 711 on the connecting frame 710 will move relative to the prism 6, thereby facilitating the wiping of the prism 6. The rainwater inside the collecting trough 701 will flow out along the first connecting pipe 708 and the second connecting pipe 709. The water flowing out of the first connecting pipe 708 will flow out along the through hole 713 on the water guide frame 712, so as to realize the flushing of the surface of the prism 6. When the rain stops, the rainwater flows out from the collecting trough 701. After coming out, the sliding pin 704 will be lifted up by the elastic force of the spring 707 between the fixed block 705 and the circular block 706, and the sponge strip 711 can realize the wiping work on the prism 6 during the lifting process.

The driving rod 84 will push the supporting frame 83 to move, and the supporting frame 83 will be stuck on the upper end of the supporting rod 2. The bottom plate 82 will be supported on the lower side of the pin on the supporting rod 2. At this time, the protection frame 81 can be fixed. At this time, the rotating bar 85 on the protection frame 81 is rotated to squeeze the screw 86 on the upper side of the baffle 702, which can realize the shielding of the upper side of the protection box 5. At this time, the protection frame 81 can realize the protection of the parts in the position of the protection box 5, thereby improving the safety of the foundation pit monitoring and protection mechanism during transportation. By setting the protection structure 8, the shielding and protection work of the foundation pit monitoring and protection mechanism is facilitated, and the safety of the foundation pit monitoring and protection mechanism during transportation is improved.
