Description

Technical Field

[0001] The utility model relates to the technical field of groundwater detection, in particular to a groundwater detection device for coal mine filling. Background Art

[0002] In order to avoid environmental pollution caused by the large amount of solid waste generated during coal mining, the existing backfill mining technology not only solves the problem of solid waste stacking occupying land and polluting the surface environment, but also prevents surface subsidence caused by coal mining. However, when the backfill paste is filled into the goaf, the harmful components in the backfill paste may enter the groundwater environment under the action of mine water and cause pollution. Experimental research analyzes the impact of the backfill paste on the groundwater environment after it is filled into the goaf.

[0003] When testing groundwater, it is usually necessary to collect groundwater from coal mines and then send it to the laboratory for sample sampling. Since the groundwater in coal mines is in a flowing state, when a sampling tube is placed in the well for collection, the sampling tube is easily floated with the water flow, and the depth of the sampling tube cannot be effectively controlled, making the collected water samples inaccurate.

[0024] like Figure 1-4 As shown, a technical solution provided by the utility model:

[0025] A groundwater detection device for coal mine filling, comprising a frame 1, a top plate 2 is fixedly mounted on the top of the frame 1, a box body 3 is fixedly mounted on the top of the top plate 2, a storage box 4 and a water tank 5 are arranged side by side below the bottom end of the top plate 2; a motor 6, the motor 6 is fixedly mounted on the left side of the top plate 2, a second reel 7 and a first reel 8 are arranged side by side on the output shaft of the motor 6, a sampling tube 9 is wound around the outside of the first reel 8, a counterweight ball 10 is arranged on the outside of the bottom end of the sampling tube 9, and a delivery tube 11 is wound around the outside of the second reel 7; an adjustment mechanism is arranged on the left side of the interior of the box body 3, the adjustment mechanism comprises a liquid storage tank 12 and a water pump 13, the liquid storage tank 12 is opened in the middle of the box body 3, the water pump 13 is installed on the left side of the interior of the box body 3, the two ends of the water pump 13 are respectively connected to the liquid storage tank 12 and the delivery tube 11, the other end of the delivery tube 11 is connected to the counterweight ball 10, and moving wheels 18 are arranged at the four corners of the bottom end of the frame 1;

[0026] In this embodiment, when it is necessary to adjust the depth of the sampling tube 9 in the water, the water pump 13 is started, the water pump 13 draws out the liquid in the liquid storage tank 12, and then sends it into the counterweight ball 10 through the delivery pipe 11. The density of the liquid stored in the liquid storage tank 12 is greater than the density of water. After being poured into the counterweight ball 10, the counterweight ball 10 can be controlled to drive the sampling tube 9 to sink to adjust the height, thereby achieving the purpose of facilitating collection and adjustment.

[0027] like Figure 2 As shown, a sampling mechanism is provided on the right side of the interior of the box body 3, and the sampling mechanism includes a centrifugal pump 14, which is fixedly installed on the right side of the interior of the box body 3, and the two ends of the centrifugal pump 14 are respectively connected to the interior of the water tank 5 and the outside of the box body 3, and the end of the sampling tube 9 away from the counterweight ball 10 is connected to the water tank 5;

[0028] In this embodiment, after the height of the sampling tube 9 is adjusted, the centrifugal pump 14 is started. The centrifugal pump 14 extracts the air inside the water tank 5 to form a negative pressure state. At this time, the water sample enters from the bottom of the sampling tube 9 and then flows into the water tank 5 for storage. When testing, the water sample can be taken out from the sampling port 17. This makes sampling and testing more convenient.

[0029] like Figure 4 As shown, a filter tip 15 is provided at one end of the sampling tube 9 close to the weighted ball 10;

[0030] In this embodiment, a filter 15 is installed at the bottom of the sampling tube 9 to prevent debris in the groundwater from entering the sampling tube 9 and causing pipe blockage.

When it is necessary to adjust the depth of the sampling tube 9 in the water, the water pump 13 is started, and the water pump 13 extracts the liquid in the liquid storage tank 12, and then sends it into the counterweight ball 10 through the conveying tube 11. Among them, the density of the liquid stored in the liquid storage tank 12 is greater than the density of water. After the liquid is poured into the counterweight ball 10, the counterweight ball 10 can be controlled to drive the sampling tube 9 to sink to adjust the height; when the height of the sampling tube 9 is adjusted, the centrifugal pump 14 is started, and the centrifugal pump 14 extracts the air inside the water tank 5 to form a negative pressure state. At this time, the water sample enters from the bottom of the sampling tube 9 and then flows into the water tank 5 for storage. During detection, the water sample can be taken out from the sampling port 17.
