A rack 204 is fixedly mounted on one side of the slide post 203. The rack 204 passes through the first slide 202 and extends to the outside of the mounting cylinder 201. The rack 204 is slidably connected to the first slide 202. The top of the chassis 11 is fixedly mounted. A fixed box 205 is provided, wherein a rotating shaft 206 is rotatably installed inside the fixed box 205, a gear 207 and a worm wheel 208 are fixedly installed on the rotating shaft 206 respectively, the gear 207 is engaged with the rack 204, a worm shaft 209 is rotatably installed on the fixed box 205, the worm shaft 209 is engaged with the worm wheel 208, one end of the worm shaft 209 passes through the fixed box 205 and extends to the outside of the fixed box 205, and a handle 210 is fixedly installed on one end of the worm shaft 209 on the outside of the fixed box 205.

[0025] Specifically, the worm shaft 209 is driven to rotate by the handle 210, and the worm shaft 209 drives the sliding column 203 to move through the gear 207 and the rack 204, so as to realize the lifting and lowering of the early warning structure 3.

The early warning structure 3 can be folded up in the non-working state, which is convenient for maintenance and replacement and prolongs the service life.

[0026] Example 2:

[0027] Please see the attached Figure 5 and attached Figure 6 The warning structure 3 includes a fixed cylinder 301, which is fixedly installed at the bottom end of the sliding column 203. The side wall of the fixed cylinder 301 is symmetrically provided with a second sliding groove 302. A fixed rod 303 is fixedly installed inside the fixed cylinder 301. A fixed plate 305 is slidably installed on the fixed rod 303. Both ends of the fixed plate 305 pass through the second sliding groove 302 and extend to the outside of the fixed cylinder 301. The fixed plate 305 is slidably connected to the second sliding groove 302. A spring 304 is sleeved on the fixed rod 303. One end of the spring 304 is fixedly connected to the fixed cylinder 301. The other end of the spring 304 is fixedly connected to the fixed plate 305, and the two ends of the fixed plate 305 are fixedly installed with the mounting plate 307 through the connecting rod 306. The top of the mounting plate 307 is fixedly installed with the contact block 308, and the end of the mounting plate 307 away from the contact block 308 is fixedly installed with the air bag 309. The bottom end of the fixed tube 301 is fixedly installed with the contact block 310 that cooperates with the contact block 308.

[0028] Specifically, in the early warning structure 3, the rising water level drives the airbag 309 to rise, and the airbag 309 contacts the contact block 308 through the mounting plate 307, triggering a signal to the buzzer 312 to make a sound. The early warning method is reliable and reduces false alarms or missed alarms. The water level directly acts on the airbag 309, triggering it quickly, and the buzzer 312 immediately reminds the operator. There is no need for real-time monitoring, which reduces labor costs.

[0029] Working principle of the present invention: The present invention is a geological underground water prevention and control early warning device. The supporting structure 1 is moved to the wellhead, the movable rod 13 is inserted into the ground, and then the limit frame 12 is adjusted to level the chassis 11. Then the fastening bolts 14 are tightened, and the movable rod 13 is limited and fixed by the fastening bolts 14. The handle 210 is turned to drive the worm shaft 209 to rotate through the handle 210, and the worm shaft 209 drives the worm wheel 208 to rotate. The worm wheel 208 drives the gear 207 to rotate through the rotating shaft 206. Because of the meshing relationship between the gear 207 and the rack 204, the gear 207 drives the rack 204 to slide in the first slide groove 202, and drives the sliding column 203 to slide in the installation cylinder 201 through the rack 204, and drives the early warning structure 3 to descend through the sliding column 203, and lowers the early warning structure 3 to the required early warning height.

[0030] When the water in the well rises and contacts the airbag 309, the water will give the airbag 309 an upward force. When the water level continues to rise, the airbag 309 will drive the mounting plate 307 to rise. The mounting plate 307 will drive the fixed plate 305 to rise through the connecting rod 306. At the same time, the fixed plate 305 will compress the spring 304, and the mounting plate 307 will drive the contact block 308 to rise. When the contact block 308 contacts the contact block 310, a signal will be sent to the buzzer 312, which will sound to alert the staff, thereby achieving an early warning of the water level.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
