Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0050] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, an embodiment of the present invention provides a multifunctional device for groundwater quality detection and groundwater level measurement, including a probe rod 1, a hollow conduit 2, an air extraction device 16, a connecting chamber 7, a water quality detection chamber 8, a water intake chamber 10 and a water level measuring device 12. One end of the probe rod 1 is connected to the top of the connecting chamber 7. In this embodiment, the connection method between the probe rod 1 and the connecting chamber 7 can be screw connection, clamping connection, etc.

[0051] The probe rod 1 is hollow and a hollow conduit 2 is arranged inside. The upper end of the hollow conduit 2 is connected to the vacuum device 16. The installation method can be screw connection, extrusion, snap connection, etc. It is used to discharge the air inside the device when taking water samples, so that groundwater can smoothly enter the equipment.

[0052] The lower end of the hollow conduit 2 passes through the connecting chamber 7 to the top of the water quality detection chamber 8. One end of the hollow conduit 2 is fixedly connected to the cover plate 13. The connection method can be screw connection, extrusion, snap connection, etc. A sealing plug group 17 is provided on the upper part of the cover plate 13, and a through hole 61 is provided at the bottom of the hollow conduit 2. A fixed partition 14 is provided on the top of the water quality detection chamber 8. A through hole group 62 is opened on the partition 14, and a non-through reserved groove 23 is also provided. When the hollow conduit 2 drives the cover plate 13 to lift up, the sealing plug group 17 leaves the through hole group 62, and the through hole 61 leaves the reserved groove 23. At this time, all through holes are in a connected state.

[0053] In this embodiment, if Figure 3 and Figure 6 As shown, the sealing plug group 17 can be screwed, extruded or snapped onto the surface of the cover plate 13, and an alarm 19 is installed at the lower part of each sealing plug in the sealing plug group 17. The alarm 19 can also be screwed, extruded or snapped onto the outer surface of the bottom end of each sealing plug. When the mixed liquid of groundwater and detection reagent fills the test tube bundle 9, the alarm device is triggered, and the air extraction is stopped at this time to prevent the test mixed liquid (groundwater and detection reagent) from overflowing the test tube bundle 9.

[0054] In this embodiment, if Figure 2 and Figure 5 As shown, the upper part of the test tube bundle 9 can be detachably screwed or snapped onto the through hole group 62, wherein each test tube in the test tube bundle 9 is independent and connected to each through hole in the through hole group 62, and the lower end of the test tube bundle 9 is sealed and can also be detachably screwed, squeezed or snapped onto the top outer surface of the partition 15.

[0055] In this embodiment, if Figure 2 、 Figure 4 and Figure 5 As shown, the upper portion of the water intake pipe bundle 11 is sealed and can be detachably screwed, squeezed, or snapped onto the bottom outer surface of the partition 15. The lower end of the water intake pipe bundle 11 is open and can be detachably screwed, squeezed, or snapped onto the bottom through-hole group 64 of the bottom plate 22. The water intake pipes in the water intake pipe bundle 11 are independently and continuously connected to the through-holes in the through-hole group 64. When used to take groundwater samples, groundwater can enter the test pipe bundle 11 through the through-hole group 64.

[0056] In this embodiment, if Figure 2 and Figure 5 As shown, a connecting hole is provided on the side wall of each test tube constituting the test tube bundle 9, and a connecting hole is also provided on the side wall of each water intake pipe constituting the water intake pipe bundle 11. The connecting holes of each test tube and each water intake pipe are individually and tightly connected via a connecting conduit 18. When taking water samples, groundwater can enter each test tube from the water intake pipe through the connecting conduit 18.

[0057] In this embodiment, if Figure 2 and Figure 6 As shown, the water level measuring device 12 can be detachably screwed, squeezed or snapped onto the outer surface of the base plate 22. A water inlet hole 20 is provided at the bottom of the water level measuring device 12 for measuring the water level. When groundwater enters the measuring device and the alarm device is connected, the groundwater level can be measured.

[0058] In this embodiment, the probe rod 1 and the connecting chamber 7, the connecting chamber 7 and the water quality detection chamber 8, the water quality detection chamber 8 and the water intake chamber 10, the water intake chamber 10 and the water level measuring device 12 can be disassembled at will, and their connection methods can be screw connection, snap connection, etc.

[0059] Specifically, a filter screen of matching size is provided on each through hole to filter out impurities and other substances when taking water samples.

[0060] In this embodiment, the probe rod 1 is provided with a scale on its exterior to facilitate depth measurement during water sampling and groundwater measurement. The probe rod 1 comprises a plurality of sequentially connected sub-probe rods 1. The length of each sub-probe rod 1 can be flexibly adjusted for portability and ease of use. For example, each sub-probe rod 1 is 50 cm long, allowing for flexible assembly based on operational requirements such as sampling depth.

[0061] In this embodiment, the other end of the probe rod 1 is connected to a rotating rod 4, and the connection method can be threaded connection, clamping, etc. The rotating rod 4 and the probe rod 1 are in a T-shaped structure, which is convenient for the use and operation of the entire device.

[0062] In this embodiment, if Figure 2 As shown, the hollow conduit 2 includes several detachable sub-hollow conduits 2. For example, each sub-hollow conduit 2 is 50 cm long and can be assembled flexibly.

[0063] The hollow catheter 2 is passed through the hollow probe rod 1 and one end extends out of the rotating rod 4. A locking mechanism 3 for fixing and locking the hollow catheter 2 is provided on the upper part of the rotating rod 4. At this time, the probe rod 1 is a hollow structure, and the hollow chamber of the probe rod 1 is sealed with the chamber of the connecting chamber 7 to prevent air leakage.

[0064] Next, the use and operation of the multifunctional device for detecting groundwater quality and measuring groundwater level will be described in detail with reference to the embodiments of the present invention as follows:

[0065] According to the estimated depth of groundwater, take the required number of probe rods 1 and connect them together through threads;

[0066] Place the cover plate 13 in the cavity of the connecting chamber 7, assemble several sub-rods of the hollow conduit 2 and fix one end thereof to the cover plate 13;

[0067] Connect the probe rod 1 to the upper part of the connecting chamber 7, and insert the other end of the hollow conduit 2 connected to the cover plate 13 into the cavity of the probe rod 1 through the reserved hole at the top of the connecting chamber 7 to extend the sub-rod;

[0068] Extend the hollow catheter 2 through the small hole reserved in the rotating rod 4, and connect the rotating rod 4 to the probe rod 1;

[0069] Connect the partition 14 to the bottom of the connecting chamber 7. Simultaneously, the hollow conduit 2 drives the cover 13 downward, so that the sealing plugs 17 seal the through-holes 62 on the partition 14. Meanwhile, the through-holes 61 are located in the reserved grooves 23. At this point, the hollow conduit 2 is fixed to the rotating rod 4 by the locking mechanism 3.

[0070] Place the test tubes or a portion of the test tubes in the test reagents, then place the test tubes in the water quality testing chamber 8. Connect the connecting pipes 18 to the connecting holes on the test tubes one by one. Install the water quality testing chamber 8 with the connected test tube bundle 9 to the bottom of the partition 14, and ensure that the connecting pipes 18 extend out of the through-hole group 63 of the partition 15.

[0071] Install the water intake chamber 10 connected to the water intake pipe bundle 11 to the bottom of the partition 15, and connect each connecting conduit 18 to the connection hole on the corresponding water intake pipe.

[0072] The bottom plate 22 is connected to the bottom of the water intake chamber 10, and the water intake pipe bundle is installed correspondingly at the through holes 64, so that each water intake pipe corresponds to each through hole.

[0073] The water level measuring device (alarm) 12 is mounted on the bottom surface of the bottom plate 22;

[0074] Install the air extraction device 16 to the upper part of the hollow conduit 2;

[0075] Slowly place the installed device into the borehole, exploration well or exploration pit. When the alarm 12 sounds, stop placing it and read the scale on the upper part of the probe rod 1. At this time, the height of the groundwater to the ground can be calculated (Note: the height of the device other than the probe rod 1 should be measured in advance);

[0076] At this time, the locking mechanism 3 is opened, and the hollow conduit 2 is lifted to a suitable position, so that the through hole 61 is removed from the reserved groove 23, and the sealing plug group 17 is removed from the through hole group 62. The alarm 19 is still in the through hole group 62, but it does not affect the connection of the through holes in the device.

[0077] Open the air extraction device 16 and slowly extract the gas in the device so that the groundwater enters the test pipe bundle 9 through the water intake pipe bundle 11. Stop the air extraction when the alarm 19 sounds.

[0078] At this point, the in-situ groundwater quality detection and groundwater level measurement work is completed. If multiple detections and measurements are required, the above operations can be repeated.

[0079] After completing the above work, disassemble the multi-function device, wipe each component clean, and store it.

[0080] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
