[0029] Reference Figure 1 , Figure 4 , Figure 5As shown, the control assembly 3 includes a control box 301, and the control box 301 is provided with a circular hole 302. The control box 301 is fixedly connected to the water injection pipe 11 through the circular hole 302. The wire rope 12 slides through the bottom of the control box 301. The control box 301 also includes a sliding rod 303. The sliding rod 303 has two groups. The two groups of sliding rods 303 are fixedly installed inside the control box 301. The two groups of sliding rods 303 are slidably connected with a circular ring 305. A lifting rod 307 is connected between the circular rings 305. A vertical rod 312 is installed at the center position of the upper surface of the lifting rod 307. The upper end of the vertical rod 312 is connected to an insulating base 311. A conductive plate 304 is installed on the upper end of the insulating base 311. The conductive plate 304 is engaged with a plug rod 309. The plug rod 309 has a groove 310 that is slidably adapted to the conductive plate 304. The upper end of the wire rope 12 is connected to a rotating plate 306. The rotating plate 306 is below the lifting rod 307. The plate 306 is rotatably connected to a round rod 308, and the round rod 308 is fixedly installed inside the control box 301. When the underground water level in the water replenishment well drops, the air bag 14 is driven to drop under the action of the counterweight 13. The descent of the air bag 14 drives the steel wire rope 12 to be pulled down, and the downward pulling of the steel wire rope 12 drives the rotating plate 306 to rotate in the direction of the steel wire rope 12 (the end away from the steel wire rope 12 is tilted upward), and the upward tilting of the rotating plate 306 drives the lifting rod 307 to rise, and the rising of the telescopic rod drives the ring 305 to slide upward along the slide rod 303, and the lifting rod 307 rises and drives the vertical rod 312 to move upward, and the upward movement of the vertical rod 312 drives the insulating base 311 and the conductive plate 304 to move upward. When the water level drops to the warning water level, the conductive plate 304 rises and is inserted into the groove 310 in the plug 309. At this time, the circuit of the second water pump 10 is in the connected state, and the second water pump 10 works to pump the water inside the water storage tank 1 into the water replenishment well.

[0030] Working principle: The device is installed near the water replenishment well, wherein the water storage tank 1, the filter assembly 2, and the control assembly 3 are on the ground, and the vertical end of the water injection pipe 11, the air bag 14, and the counterweight block 13 are inside the water replenishment well;

[0031] First, water is poured into the water storage tank 1. When a large amount of groundwater seeps out from the foundation pit, the water inside the foundation pit is transported to the filter assembly 2 through the drainage device. Specifically, the water in the foundation pit is transported to the water injection port 205. The groundwater then passes through the filter plate 206, and large particles are filtered under the action of the filter holes. The filtered groundwater then enters the pumping tank, and the first water pump 6 is started to pump the filtered groundwater into the connecting pipe. The groundwater then enters the water storage tank 1. The second water pump 10 is started to pump the groundwater into the injection pipe 11 to replenish the water well and control the water level above the warning water level (at this time, the air bag 14 is above the warning water level, and the buoyancy of the air bag 14 is adapted to the counterweight block 13). When it is necessary to clean the filter plate 206, the debris remaining on the upper surface of the filter plate 206 is removed through the water injection port 205, and then the filter plate 206 is removed by using the mounting plate 207, and the impurities inside the filter holes are cleaned. After the cleaning is completed, the filter plate 206 is reinstalled;

[0032] When the underground water level in the water replenishment well drops, the counterweight 13 drives the airbag 14 to drop, and the dropping of the airbag 14 drives the steel wire rope 12 to be pulled down, and the pulling down of the steel wire rope 12 drives the rotating plate 306 to rotate in the direction of the steel wire rope 12 (the end away from the steel wire rope 12 is tilted up), and the tilting of the rotating plate 306 drives the lifting rod 307 to rise, and the lifting of the telescopic rod drives the ring 305 to slide upward along the sliding rod 303, and the lifting rod 307 drives the vertical rod 312 to move upward, and the vertical rod 312 moves upward to drive the insulating base 311 and the conductive plate 304 to move upward. When the water level drops to the warning water level, the conductive plate 304 rises and is inserted into the groove 310 in the plug rod 309. At this time, the circuit of the second water pump 10 is connected, and the second water pump 10 works to pump the water inside the water storage tank 1 into the water replenishment well. When the groundwater level rises to the original position, the steel wire rope 12 does not pull the rotating plate 306 downward. Under the action of gravity, the upturned end of the rotating plate 306 falls and drives the conductive plate 304 to break away from the plug rod 309. The second water pump 10 stops working. When the warning water level is reached next time, the second water pump 10 continues to work.

[0033] When the groundwater inside the foundation pit is insufficient for use, river water, tap water, etc. can be connected through the water pipe 5 to continue to replenish the water storage tank 1.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein.
