Example

[0037] Based on the first embodiment, the specific working principle is as follows:

[0038] The landslide monitoring device for ecological restoration of a mine first connects the top movable sleeve 3 and the bottom of the fixed sleeve 2 to each other, and the connecting protrusions 4 between the two movable sleeves 3 are engaged with the inside of the installation opening 5, so that the adjacent distributed movable sleeves 3 are connected to each other, and the pressure cone 10 is pulled upward by the pull rope 11, so that the bottom of the movable sleeve 3 is subjected to an upward force, thereby making the connection between the movable sleeve 3 and the fixed sleeve 2 tighter, so that the fixed sleeve 2, the pressure cone 10 and the plurality of movable sleeves 3 form a whole, and then a hole is drilled at the position where the mine needs to monitor the landslide by a punching device, and the fixed sleeve 2, the pressure cone 10 and the plurality of movable sleeves 3 are formed into a whole and inserted into the opening, and then the pull rope 11 is loosened, so that the fixed sleeve 2, the pressure cone 10 and the plurality of movable sleeves 3 are formed into a whole and placed in the opening in a relaxed state;

[0039] First, the slider 20 is pulled away from the engaging wheel 18, so that the engaging wheel 18 and the slider 20 are separated from each other, until the slider 20 cannot interfere with the movement of the engaging wheel 18. At this time, the rope winding roller 16 is driven to rotate outside the bracket 15 by rotating the toggle plate 17, thereby controlling the downward extension length of the pull rope 11. By superimposing different numbers of movable sleeves 3, the length of the fixed sleeve 2, the pressure cone 10 and the plurality of movable sleeves 3 as a whole is adjusted, and landslide monitoring of geological structures at different depths is achieved according to the excavation depth of the mine;

[0040] When the fixed sleeve 2, the pressure cone 10 and the multiple movable sleeves 3 form a whole and are located inside the opening, air is inflated into the connection valve 14, and the gas inside the connection valve 14 passes through the air guide tube 12 and is diverted by the shunt tube 13, so that the gas enters the airbag 7 through the multiple shunt tubes 13 respectively, so that the airbag 7 extends from the inside of the groove of the movable sleeve 3 to the outside of the movable sleeve 3, and the airbag 7 continues to expand until the airbag 7 is completely fitted with the inner wall of the opening, thereby stably fixing the movable sleeve 3 inside the opening;

[0041] The fixing plate 1 is internally provided with a single-chip microcomputer and a remote communication structure, and the monitoring ring 6 is electrically connected to the single-chip microcomputer and the remote communication structure inside the fixing plate 1. When the two movable sleeves 3 are connected to each other, the connecting protrusion 4 is located inside the mounting opening 5 at this time. When a landslide occurs in the mine or the soil layer is displaced, the multiple movable sleeves 3 located inside the opening holes will be misaligned. When the connecting protrusion 4 is displaced inside the mounting opening 5, the connecting protrusion 4 will gradually separate from the monitoring ring 6 until it is completely separated. The monitoring ring 6 transmits the separation signal to the inside of the fixing plate 1. At this time, the opening structure at the position where landslide monitoring is required in the mine changes greatly, and the connecting protrusion 4 is separated from the mounting opening 5 and the monitoring ring 6, so that the connecting protrusion 4 cannot be monitored inside the monitoring ring 6. Furthermore, the connection situation between the monitoring ring 6 and the connecting protrusion 4 is sent to the terminal device through the remote communication structure inside the fixing plate 1 to realize real-time monitoring of the landslide situation in the mine.
