6. The ground subsidence monitoring and early warning device based on the surface deformation according to claim 1, wherein: the driving gears (602) are fixedly sleeved on the outer wall of the driving rod (601), and the driving gears (602) are arranged at equal intervals.
7. The ground subsidence monitoring and early warning device based on the surface deformation according to claim 1, wherein: the utility model discloses a telescopic device, including column (3) and annular groove (12), the terminal surface is fixed to be provided with awl head (4) under column (3), drive slot (8) and drive slot (8) inside midpoint department are fixedly provided with the baffle have been seted up to drive piece (1) up end, drive piece (1) outer wall one side midpoint department embedding is provided with joint piece and joint piece is located battery (9) one side, two equal fixed connection abaculus of shrink spring (10) lower extreme and abaculus all movable embedding set up in annular groove (12).
8. The application method of the ground subsidence monitoring and early warning device based on the ground surface deformation is characterized by comprising the following steps of:
s1, prefabrication adjustment
Firstly checking the residual quantity of the battery electric quantity embedded in the device, selecting whether to replace according to the residual quantity, and rotating the sleeve block on the outer side to enable the sleeve block to be in the same horizontal plane with the upper surface of the driving block after the replacement is completed;
s2, embedding
Firstly, embedding the early warning device into the subsurface end of the early warning area to be monitored, clamping a partition board in a driving groove by using a clamping tool after embedding, and rotating, wherein the outer wall of a column body at the embedded lower end is outwards protruded blocks from inside to outside, the protruded blocks are early warning mechanisms, and one end of each early warning mechanism is embedded into soil to finish embedding;
s3, monitoring and early warning
After the embedding is finished, as the outer wall of the column body is provided with a plurality of notches for outwards moving the convex blocks, the vertical heights of the notches are different, the convex blocks at each height position monitor the soil foundation with the corresponding depth, when the soil with the depth collapses, the lower end of the movable block embedded in the soil of the early warning mechanism is not stressed to drop, so that one side of the movable block is driven to move by the stop block and the pushing block connected by the connecting rope, and the pushing block extrudes the inclined block to drive the hammer block to trigger the touch button, and the monitoring and early warning are finished at the moment;
s4, processing
The current depth value and the position can be judged according to the trigger signal value of the trigger button at the depth, so that the collapse azimuth depth of the area can be rapidly judged and processed;
s5, inspection
And periodically inspecting the residual battery electric quantity of the monitoring and early warning device, and rotating the sleeve block downwards to finish the replacement inspection of the storage battery.
