[0015] Furthermore, the inner wall of the circular body slides against the outer wall of the detection tube, and several sets of water injection pipes are movably connected in a ring array on the circular body, with an auxiliary water storage tray connected to the top of each set of water injection pipes.

[0017] A detection method for a groundwater detection device, characterized in that: the detection method includes:

[0018] The water-absorbing structure is activated, drawing groundwater into the water storage pipe.

[0019] Activate the water absorption assembly to collect the targeted groundwater;

[0020] The water-absorbing assembly is activated to descend into the groundwater for sample collection.

[0021] For single-sample groundwater testing, the groundwater placed in the sampling assembly flows into the testing tube;

[0022] The water quality monitoring probe was activated to test the groundwater.

[0023] The beneficial effects of this invention are:

[0024] 1. The collected groundwater flows into the detection tube. The first electric push rod is activated to lower the limit plate, which in turn drives the water quality monitoring probe to perform single-sample groundwater testing. When performing groundwater mixed testing, groundwater from different depths gathers in the detection tube. Then, the second electric push rod is activated to drive two sets of stirring tubes into the groundwater. Subsequently, two sets of servo motors are activated to drive the two sets of stirring tubes to rotate in opposite directions, accelerating the mixing effect of groundwater in the detection tube. Then, the water quality monitoring probe is activated to test the mixed groundwater, which improves the diversity of detection and the mixing effect of groundwater.

[0025] 2. Start the water pump. The water pump drives the water source in the auxiliary water storage pan through the constant temperature pipe, the third suction pipe, the first suction pipe, and the second suction pipe in sequence into the water storage tank. During the water suction process, the water is filtered to isolate floating debris, so as to ensure the quality of the sampled water source. When the next set of tests is required, first open the second electric ball valve to allow the cleaning liquid in the water tank to flow into the test tube, clean the groundwater remaining in the test tube, and improve the accuracy of the test.

[0026] 3. Using pressure, the water remaining in the storage pipe is sprayed out through the suction structure, and then the storage pipe descends again into the groundwater. When it descends to the designated height again, the suction structure collects the sample again. Then, another set of different fifth electric ball valves is opened to collect the water in the auxiliary storage pan. Then, another set of storage tanks is activated to collect the water. This process is repeated, so that several sets of storage tanks contain groundwater samples at different depths. This avoids the problem of multiple water sampling trips and improves the convenience of sampling.

[0027] 4. The water suction structure is activated to draw groundwater into the storage pipe. One set of fifth electric ball valves is opened to connect the upper and lower spaces of the ring body. Then, the third electric push rod is activated to push the ring body down. Once it reaches the designated position, the water flow is squeezed. Since only one set of fifth electric ball valves is connected, the water flow will then enter the auxiliary water storage pan through the water injection pipe. Before entering the auxiliary water storage pan, impurities are removed by passing through insulating gauze, which improves the sampling quality and the controllability of the sampling location.

[0028] Other features and advantages of the invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention may be realized and obtained by means of the structures pointed out in the description, claims and drawings. Attached Figure Description

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] This invention provides a groundwater detection device. It includes a working box 1, exemplarily, such as... Figure 1 and Figure 2 As shown, one end of a stretching tube 2 is installed on one side wall of the working box 1, and a detection component 3 is installed on the other end of the stretching tube 2. A water absorption component 4 is movably snapped onto the detection component 3, and several sample components 5 are distributed in a ring array on the outer wall. An auxiliary component 6 is installed on the detection component 3.

[0041] For example, such as Figure 3 and Figure 4As shown, the detection assembly 3 includes a sealing cover 301. The top of the sealing cover 301 is mounted on the tension tube 2. Several sets of snap-fit ​​rods 302 are arranged in a circular array on 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 chamber 304 is connected to the outer wall of the detection tube 303. A first electric ball valve 305 is installed at the junction of the vacuum chamber 304 and the detection tube 303. A vacuum pump 306 is mounted on the top of the vacuum chamber 304. A water tank 307 is connected to the end of the detection tube 303 away from the vacuum chamber 304. The water tank 307 is connected to the detection tube 303. A second electric ball valve 308 is installed on the top inner wall of the detection tube 303. A first electric push rod 309 is installed on the top inner wall of the detection tube 303. A limiting plate 310 is installed on the output end of the first electric push rod 309. The outer wall of the limiting plate 310 slides against the inner wall of the detection tube 303. A water quality monitoring probe 311 is installed at the bottom center of the limiting plate 310. Two sets of second electric push rods 312 are symmetrically installed on the bottom edge of the limiting plate 310. A set of servo motors 313 is installed on the output end of each set of second electric push rods 312. A set of stirring tubes 314 is drivenly connected to the output end of each set of servo motors 313. A set of threaded grooves is opened on the outer wall of each set of stirring tubes 314.

[0042] To begin groundwater testing, the first electric ball valve 305 is opened, connecting the vacuum chamber 304 and the detection tube 303. The vacuum pump 306 is then activated to evacuate the air from the detection tube 303, creating a negative pressure environment. A single groundwater sample is then tested by opening one of the fourth electric ball valves 505, allowing groundwater from the storage tank 504 to flow into the detection tube 303. The first electric push rod 309 is then activated, pushing the limit plate 310 downwards. As the limit plate 310 descends, the water quality monitoring probe 311 detects the groundwater. When the next test is needed, the second electric ball valve 308 is opened, allowing cleaning fluid from the water tank 307 to flow into the detection tube 303, cleaning any remaining groundwater. The fluid is then discharged through the third electric ball valve 315, improving the accuracy of the test.

[0043] When conducting groundwater mixing detection, several sets of designated fourth electric ball valves 505 are opened, causing groundwater at different depths to gather in the detection tube 303. Then, the second electric push rod 312 is activated to drive two sets of stirring tubes 314 into the groundwater. Subsequently, two sets of servo motors 313 are activated to drive the two sets of stirring tubes 314 to rotate in opposite directions, accelerating the mixing effect of groundwater in the detection tube 303. Then, the water quality monitoring probe 311 is activated to detect the mixed groundwater, which improves the diversity of detection and the mixing detection effect of groundwater.

[0044] For example, such as Figure 5 As shown, the water absorption component 4 includes a water storage pipe 401. The top of the water storage pipe 401 has an open structure. Several sets of snap-fit ​​holes 402 are arranged in a ring array at the top edge of the water storage pipe 401. The snap-fit ​​holes 402 are movably snapped into the snap-fit ​​rod 302. The bottom of the water storage pipe 401 is connected to a water absorption structure 403.

[0045] The third electric push rod 601 is activated to push the circular body 604. The circular body 604 begins to squeeze the water remaining in the water storage pipe 401. The pressure drives the water to be sprayed out through the water suction structure 403. Then, the water storage pipe 401 is driven to descend into the groundwater again. When it descends to the designated height again, the water suction structure 403 is used to collect the sample again. Another set of different fifth electric ball valves 608 is opened to drive the auxiliary water storage pan 606 to collect the sample. Then, another set of water storage tanks 504 is driven to collect the water. This process is repeated so that several sets of water storage tanks 504 contain groundwater samples at different depths. This avoids the problem of multiple water samplings and improves the convenience of sampling.

[0046] For example, such as Figure 6 As shown, the sample separation component 5 includes a first suction pipe 501. One end of each set of first suction pipes 501 is connected to one end of a set of second suction pipes 503. The other end of each set of second suction pipes 503 is connected to a set of water storage tanks 504. A gauze pad is installed on the inner wall of the top of each set of water storage tanks 504. A fourth electric ball valve 505 is installed at the junction of each set of water storage tanks 504 and detection tubes 303. A water pump 502 is installed on the outer wall of each set of first suction pipes 501. A third suction pipe 506 is connected to the end of each set of first suction pipes 501 away from the second suction pipes 503. A gauze membrane is installed inside each set of third suction pipes 506. A thermostatic tube 507 is connected to the end of each set of third suction pipes 506 away from the first suction pipes 501.

[0047] Start the water pump 502. The water pump 502 drives the water source in the auxiliary water storage pan 606 to enter the water storage tank 504 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 in sequence. During the water suction process, the water is isolated by gauze membrane and gauze pad layer in sequence to ensure the quality of the sampled water source.

[0048] For example, such as Figure 7 and Figure 8 As shown, the auxiliary component 6 includes a third electric push rod 601. The top of the third electric push rod 601 is mounted on the bottom of the sealing cover 301. A vibration motor 602 is mounted on the output end of the third electric push rod 601. A transmission pipe 603 is connected to the output end of the vibration motor 602. A circular ring body 604 is mounted on the bottom of the transmission pipe 603. The outer wall of the circular ring body 604 slides against the inner wall of the water storage pipe 401, and the inner wall of the circular ring body 604 slides against the outer wall of the detection pipe 303. The ring body 604 has several sets of water injection pipes 605 connected in a ring array. Each set of water injection pipes 605 is connected to an auxiliary water storage tray 606 at the top. Each set of auxiliary water storage trays 606 is located directly below a set of thermostatic pipes 507. The outer wall of each set of thermostatic pipes 507 is slidably attached to the inner wall of the water injection pipes 605. Each set of water injection pipes 605 is equipped with a fifth electric ball valve 608 at the bottom. Each set of insulating gauze 607 is installed at the junction of each set of water injection pipes 605 and the fifth electric ball valve 608.

[0049] The locking rod 302 engages with the locking hole 402 to seal the water storage pipe 401. Then, the tension tube 2 is pulled, causing the suction structure 403 to descend into the groundwater. When it reaches a detection depth, the suction structure 403 is activated, drawing groundwater into the water storage pipe 401. One set of fifth electric ball valves 608 is opened, connecting the upper and lower spaces of the annular body 604. Then, the third electric push rod 601 is activated, pushing the annular body 604 downwards. Once it reaches the designated position, it begins to compress the water flow. Since only one set of fifth electric ball valves 608 is in the connected state, the water will then flow into the auxiliary water storage pan 606 through the water injection pipe 605. Before entering the auxiliary water storage pan 606, impurities are removed by the insulating gauze 607, which improves the sampling quality and the controllability of the sampling position. Then, the fifth electric ball valve 608 is closed, and the third electric push rod 601 is activated to drive the auxiliary water storage pan 606 filled with groundwater to rise, thereby causing the outer wall of one set of constant temperature pipes 507 to slide and adhere to the inner wall of the water injection pipe 605.

[0050] The collected groundwater flows into the detection tube 303. The first electric push rod 309 is activated to push the limit plate 310 down, while the water quality monitoring probe 311 performs single-sample groundwater testing. When performing groundwater mixed testing, groundwater from different depths gathers in the detection tube 303. Then, the second electric push rod 312 is activated to drive two sets of stirring tubes 314 into the groundwater. Subsequently, two sets of servo motors 313 are activated to drive the two sets of stirring tubes 314 to rotate in opposite directions, accelerating the mixing effect of groundwater in the detection tube 303. Then, the water quality monitoring probe 311 is activated to test the mixed groundwater, which improves the diversity of testing and the mixing effect of groundwater.

[0051] The water pump 502 is started, and the water source in the auxiliary water storage pan 606 is driven to enter the water storage tank 504 through the constant temperature pipe 507, the third suction pipe 506, the first suction pipe 501 and the second suction pipe 503 in sequence. During the water suction process, the water is filtered to isolate floating objects, so as to ensure the quality of the sampled water source. When the next set of tests is required, the second electric ball valve 308 is opened first, so that the cleaning liquid in the water tank 307 flows into the test tube 303 to clean the groundwater remaining in the test tube 303, thereby improving the accuracy of the test.

[0052] The pressure is used to drive the water remaining in the water storage pipe 401 to be sprayed out through the water suction structure 403, and then the water storage pipe 401 is driven to descend into the groundwater again. When it descends to the designated height again, the water suction structure 403 is used to collect the sample again. Another set of different fifth electric ball valves 608 is opened to drive the auxiliary water storage pan 606 to collect the sample. Then another set of water storage tanks 504 is activated to collect the water source. This process is repeated so that several sets of water storage tanks 504 contain groundwater samples at different depths, which avoids the problem of multiple water sampling and improves the convenience of sampling.

[0053] The water suction structure 403 is activated to draw groundwater into the water storage pipe 401. One set of fifth electric ball valves 608 is opened, connecting the upper and lower spaces of the annular body 604. Then, the third electric push rod 601 is activated to push the annular body 604 down. Once it reaches the designated position, it begins to compress the water flow. Since only one set of fifth electric ball valves 608 is in the connected state, the water flow will then enter the auxiliary water storage pan 606 through the water injection pipe 605. Before entering the auxiliary water storage pan 606, impurities are removed by the insulating gauze 607, which improves the sampling quality and the controllability of the sampling position.

[0054] Based on the aforementioned groundwater detection device, this invention also proposes a detection method for the groundwater detection device. Exemplarily, the detection method includes:

[0055] The water storage pipe is sealed by engaging the locking rod with the locking hole, and the tensioning pipe is pulled to lower the water absorption structure into the groundwater.

[0056] The water-absorbing structure is activated to draw groundwater into the water storage pipe, and one of the fifth electric ball valves is opened to connect the upper and lower spaces of the annular body.

[0057] The third electric push rod is activated to push the ring body down, squeezing the water flow, which then enters the auxiliary water storage pan through the water injection pipe.

[0058] Impurities are removed by using a gauze barrier, the fifth electric ball valve is closed, and then the third electric push rod is activated to raise the auxiliary water storage pan filled with groundwater.

[0059] Start the water pump. The water pump will drive the water source in the auxiliary water storage pan through the thermostatic pipe, the third suction pipe, the first suction pipe and the second suction pipe in sequence into the water storage tank.

[0060] The third electric push rod is activated to push the ring body, which squeezes the water source remaining in the water storage pipe and uses the pressure to drive the water source to be sprayed out through the water suction structure.

[0061] The water storage pipe is lowered into the groundwater. When it reaches the designated height, a water-absorbing structure is used to collect samples.

[0062] Open the first electric ball valve to connect the vacuum chamber and the detection tube, and start the vacuum pump to evacuate the air from the detection tube.

[0063] First, perform a single groundwater test by opening one of the fourth electric ball valves, allowing the groundwater placed in the water storage tank to flow into the test tube;

[0064] The first electric push rod is activated to lower the limit plate, and as the limit plate descends, it drives the water quality monitoring probe to detect the groundwater.

[0065] Open the second electric ball valve to allow the cleaning fluid in the water tank to flow into the detection tube and clean the residual groundwater in the detection tube;

[0066] When conducting groundwater mixing tests, the fourth electric ball valve is opened to allow groundwater from different depths to collect in the test tube.

[0067] The second electric push rod is activated to drive the two sets of stirring tubes into the groundwater, and then the two sets of servo motors are activated to drive the two sets of stirring tubes to rotate in opposite directions.
