Detailed implementation manners

[0039] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0040] An embodiment of the present invention provides a detection device for groundwater. It includes a working box 1. Exemplarily, as Figure 1 and Figure 2 shown, one end of a stretching pipe 2 is installed on one side wall of the working box 1, the other end of the stretching pipe 2 is installed with a detection component 3, an absorption component 4 is movably clamped on the detection component 3, and several sample separation components 5 are distributed in an annular array on the outer wall, and an auxiliary component 6 is installed on the detection component 3.

[0041] Exemplarily, as Figure 3 and Figure 4As shown, the detection component 3 includes a sealing cover 301. The top of the sealing cover 301 is mounted on the stretching tube 2. A number of groups of clamping rods 302 are distributed in a circular array at the bottom edge of the sealing cover 301. A detection tube 303 is mounted on the bottom of the sealing cover 301. A third electric ball valve 315 is mounted on the bottom of the detection tube 303. A vacuum box 304 is communicated with the outer wall of the detection tube 303. A first electric ball valve 305 is mounted at the junction of the vacuum box 304 and the detection tube 303. A vacuum pump 306 is mounted on the top of the vacuum box 304. One end of the detection tube 303 away from the vacuum box 304 is communicated with a water tank 307. A second electric ball valve 308 is mounted at the junction of the water tank 307 and the detection tube 303. A first electric push rod 309 is mounted on the inner wall of the top of the detection tube 303. A limit disk 310 is mounted on the output end of the first electric push rod 309. The outer wall of the limit disk 310 is slidably attached to the inner wall of the detection tube 303. A water quality monitoring probe 311 is mounted at the center of the bottom of the limit disk 310. Two groups of second electric push rods 312 are symmetrically mounted at the bottom edge of the limit disk 310. A servo motor 313 is mounted on the output end of each group of second electric push rods 312. A stirring tube 314 is drivingly connected to the output end of each group of servo motors 313. A threaded groove is formed on the outer wall of each stirring tube 314.

[0042] When starting the groundwater detection work, first open the first electric ball valve 305 to make the vacuum box 304 and the detection tube 303 in a communicating state. Then start the vacuum pump 306 to evacuate the air in the detection tube 303 to form a negative pressure state. Then, first conduct a single-sample groundwater detection. Open one of the fourth electric ball valves 505 to make the groundwater placed in the water storage tank 504 flow into the detection tube 303. Then start the first electric push rod 309 to push the limit disk 310 down. While the limit disk 310 is descending, it drives the water quality monitoring probe 311 to detect the groundwater. When the next group of detections is needed, first open the second electric ball valve 308 to make the cleaning liquid in the water tank 307 flow into the detection tube 303 to clean the residual groundwater in the detection tube 303. Then discharge it through the third electric ball valve 315, which improves the accuracy of the detection.

[0043] When performing groundwater mixing detection, several specified groups of fourth electric ball valves 505 are opened so that groundwater at different depths gathers in the detection tube 303. Subsequently, the second electric push rod 312 is started to drive two groups of stirring tubes 314 to extend into the groundwater. Then, two groups of servo motors 313 are started to drive the two groups of stirring tubes 314 to rotate in opposite directions, accelerating the mixing effect of the groundwater in the detection tube 303. Subsequently, the water quality monitoring probe 311 is started to detect the mixed groundwater, improving the detection diversity and the mixing detection effect of the groundwater at the same time.

[0044] Exemplarily, as Figure 5 shown, the water absorption component 4 includes a water storage pipe 401. The top of the water storage pipe 401 is an open structure. A plurality of groups of clamping holes 402 are formed in a circular array at the top edge of the water storage pipe 401. The clamping holes 402 are movably clamped with the clamping rods 302. A water absorption structure 403 is communicated with the bottom of the water storage pipe 401.

[0045] The third electric push rod 601 is started to push the circular ring body 604. The circular ring body 604 begins to squeeze the water source remaining in the water storage pipe 401, driving the water source to spray out through the water absorption structure 403 by using the pressure. Subsequently, the water storage pipe 401 is driven to descend in the groundwater again. When it descends to the specified height again, a sample is collected again through the water absorption structure 403. Another group of different fifth electric ball valves 608 is opened again to drive the auxiliary water storage tray 606 to collect. Subsequently, another group of water storage tanks 504 is driven to collect water sources again. By repeating the operation, different depths of groundwater samples are placed in several groups of water storage tanks 504, avoiding the problem of taking samples underwater multiple times and improving the convenience of sampling at the same time.

[0046] Exemplarily, as Figure 6 shown, the sample dividing component 5 includes a first water suction pipe 501. One end of each group of first water suction pipes 501 is communicated with one end of a group of second water suction pipes 503. The other end of each group of second water suction pipes 503 is communicated with a group of water storage tanks 504. A group of gauze cushions are installed on the inner wall of the top of each group of water storage tanks 504. A group of fourth electric ball valves 505 are installed at the joint of each group of water storage tanks 504 and the detection tube 303. A group of water pumps 502 are installed on the outer wall of each group of first water suction pipes 501. One end of each group of first water suction pipes 501 far from the second water suction pipe 503 is communicated with a group of third water suction pipes 506. A group of gauze membranes are arranged in each group of third water suction pipes 506. One end of each group of third water suction pipes 506 far from the first water suction pipe 501 is communicated with a group of constant temperature tubes 507.

[0047] Start the water pump 502. The water pump 502 drives the water source in the auxiliary water storage tray 606 to enter the water storage tank 504 successively through the constant temperature pipe 507, the third water suction pipe 506, the first water suction pipe 501 and the second water suction pipe 503. And during the water suction process, it successively passes through the gauze membrane and the gauze cushion layer to isolate water floating substances, so as to ensure the quality of the sampled water source.

[0048] Exemplarily, as Figure 7 and Figure 8 shown, the auxiliary component 6 includes a third electric push rod 601. The top of the third electric push rod 601 is installed on the bottom of the sealing cover 301. A vibration motor 602 is installed on the output end of the third electric push rod 601. A transmission pipe 603 is drivingly connected to the output end of the vibration motor 602. A circular ring body 604 is installed on the bottom of the transmission pipe 603. The outer wall of the circular ring body 604 is slidably fitted to the inner wall of the water storage pipe 401. The inner wall of the circular ring body 604 is slidably fitted to the outer wall of the detection pipe 303. A number of groups of water injection pipes 605 are movably clamped on the circular ring body 604 in an annular array. A group of auxiliary water storage trays 606 are communicated with the top of each group of water injection pipes 605. Each group of auxiliary water storage trays 606 is located directly below one of the constant temperature pipes 507. The outer walls of each group of constant temperature pipes 507 are slidably fitted to the inner walls of the water injection pipes 605. A group of fifth electric ball valves 608 are installed on the bottom of each group of water injection pipes 605. A group of isolation gauzes 607 are installed at the joint of each group of water injection pipes 605 and the fifth electric ball valve 608.

[0049] The water storage pipe 401 is in a sealed state by the movable clamping connection of the clamping rod 302 and the clamping hole 402. Then, pull the stretching pipe 2 to drive the water suction structure 403 to descend into the groundwater. When at a detection depth, start the water suction structure 403 to drive the groundwater into the water storage pipe 401. Open one of the fifth electric ball valves 608 to make the upper space and the lower space of the circular ring body 604 communicate. Then start the third electric push rod 601 to push the circular ring body 604 to descend. When it descends to the specified position, start to squeeze the water flow. Since only one of the fifth electric ball valves 608 is in a communicating state, the water flow will enter the auxiliary water storage tray 606 through the water injection pipe 605. And before entering the auxiliary water storage tray 606, the impurities are removed through the isolation gauze 607, which improves the sampling quality and the controllability of the sampling position at the same time. Then close the fifth electric ball valve 608, and then start the third electric push rod 601 to drive the auxiliary water storage tray 606 filled with groundwater to rise, so that the outer wall of one of the constant temperature pipes 507 is slidably fitted to the inner wall of the water injection pipe 605.

[0050] Enable the collected groundwater to flow into the detection tube 303. Start the first electric push rod 309 to drive the limit disk 310 to descend, and at the same time drive the water quality monitoring probe 311 to perform single-sample groundwater detection. When performing mixed groundwater detection, make the groundwater at different depths gather in the detection tube 303. Then start the second electric push rod 312 to drive the two stirring tubes 314 to extend into the groundwater. Then start the two servo motors 313 to drive the two stirring tubes 314 to rotate in opposite directions to accelerate the mixing effect of the groundwater in the detection tube 303. Then start the water quality monitoring probe 311 to detect the mixed groundwater, improving the detection diversity and the mixed detection effect of the groundwater at the same time.

[0051] Start the water pump 502. The water pump 502 drives the water source in the auxiliary water storage tray 606 to enter the water storage tank 504 in turn through the constant temperature tube 507, the third water suction pipe 506, the first water suction pipe 501 and the second water suction pipe 503, and isolate water floating substances through the filtering material during the water suction process to ensure the quality of the sampled water source; when the next group of detections is required, first open the second electric ball valve 308 to make the cleaning liquid in the water tank 307 flow into the detection tube 303 to clean the residual groundwater in the detection tube 303, improving the accuracy of the detection.

[0052] Use the pressure to drive the water source remaining in the water storage pipe 401 to spray out through the water suction structure 403. Then drive the water storage pipe 401 to descend in the groundwater again. When it descends to the specified height again, collect samples through the water suction structure 403 again. Open another group of different fifth electric ball valves 608 to drive the auxiliary water storage tray 606 to collect, and then drive another water storage tank 504 to collect water source again. Repeat the operation so that different depths of groundwater samples are placed in several water storage tanks 504, avoiding the problem of taking samples underwater multiple times and improving the convenience of sampling at the same time.

[0053] Start the water suction structure 403 to drive the groundwater into the water storage pipe 401. Open one of the fifth electric ball valves 608 to make the upper space and the lower space of the circular ring body 604 communicate. Then start the third electric push rod 601 to drive the circular ring body 604 to descend. When it descends to the specified position, start to squeeze the water flow. Since only one fifth electric ball valve 608 is in the connected state, the water flow will then enter the auxiliary water storage tray 606 through the water injection pipe 605, and impurities are removed through the isolation gauze 607 before entering the auxiliary water storage tray 606, improving the sampling quality and the controllability of the sampling position at the same time.

[0054] Based on the above groundwater detection device, the embodiment of the present invention also proposes a detection method for the groundwater detection device. Exemplarily, the detection method includes:
