Description

Technical Field

[0001] The present invention relates to the technical field of groundwater pollution monitoring, and more particularly to groundwater pollution monitoring equipment. Background Art

[0002] In the field of modern environmental protection and water resources management, groundwater pollution monitoring has become a key link in ensuring water source safety and ecological health. In the existing technical system, groundwater pollution assessment mainly relies on the laboratory analysis process after sample collection. That is, water samples are extracted from underground aquifers using specialized equipment and then sent to laboratories equipped with precision instruments such as spectrometers, gas chromatographs, and mass spectrometers for comprehensive testing. Although this technical approach can provide accurate data on the types, concentrations, and distribution of pollutants, it faces significant operational difficulties in actual application. Especially when the monitoring mission is located in remote mountainous areas, desert areas, wetland reserves, or other ecologically sensitive areas with inconvenient transportation, traditional large-scale sampling equipment such as deep water pumps, high-pressure pumping systems, heavy drilling equipment, and sampling pipelines up to tens of meters long are often difficult to transport to the target monitoring points through narrow mountain roads or soft terrain due to their large size, heavy weight, and complex structure. This mismatch between equipment and the environment seriously restricts the effective deployment and regular maintenance of groundwater pollution monitoring networks in remote areas.

[0003] Forcibly deploying traditional large-scale monitoring equipment in remote areas not only faces technical feasibility challenges, but also triggers a series of far-reaching problems at the economic and practical levels. First, the transportation of equipment in special terrain usually requires the use of unconventional means such as helicopter air transport, off-road convoys or manual handling. These special transportation methods are not only costly per trip, but also require additional fuel consumption, staffing and safety measures. Secondly, the installation, operation and maintenance of equipment in complex terrain require more professional and technical personnel to be stationed on site for a long time, resulting in additional human resource expenses and logistical support pressure. More importantly, because the equipment is not adapted to the local environment, its failure rate and maintenance frequency are usually significantly increased, further increasing the project's ongoing operating costs. In environmental monitoring projects with limited budgets, this high-cost operation model often leads to a reduction in the number of monitoring points, a decrease in sampling frequency or a shortening of monitoring projects, ultimately weakening the spatial coverage and data continuity of the monitoring network, and significantly reducing the pollution trend analysis and risk warning capabilities. Summary of the Invention

[0004] (1) Technical problems solved

[0005] In view of the problems existing in the prior art, the present invention provides a groundwater pollution monitoring device to solve the technical problems mentioned in the background technology.

[0006] (2) Technical solution

[0007] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a groundwater pollution monitoring device, comprising an intermediate rope and a plurality of intermediate disks fixedly mounted on the intermediate rope; further comprising a fixing mechanism, wherein the fixing mechanism comprises two symmetrically arranged two-way tubes, the two two-way tubes are respectively provided with spiral grooves, and the two spiral grooves are fitted together, and an untying sleeve is respectively installed in each of the two-way tubes, and the two untying sleeves are slidably connected to a storage tank, a plurality of entry grooves are respectively provided on both sides of the intermediate disk, the two-way tubes abut against the entry grooves, a one-way groove is provided on the side wall of the storage tank, and a top ball is slidably installed in the one-way groove; further comprising a line clamping mechanism, the line clamping mechanism comprises a pull rope coaxially arranged with the storage tank, and a plurality of pull ropes are provided with pull rings.

[0008] Preferably, both ends of the storage tank are threadedly connected with sealing sleeves, the sealing sleeves are fitted on the inner wall of the two-way tube, and a push spring is installed on the untying sleeve, and the push spring abuts against the sealing sleeve. This design forms a double sealing structure, and the first leak-proof barrier is achieved through the precise fit between the sealing sleeve and the inner wall of the two-way tube. At the same time, the elastic resistance of the push spring provides a continuous and stable sealing pressure, ensuring that the sample is not contaminated by the outside during the groundwater sampling process.

[0009] Preferably, an internal tube is installed in the storage tank, and a transverse tube is installed between the storage tank and the internal tube, and the transverse tube is connected to the one-way groove. This coaxial sleeve structure design creates an independent water sample flow channel, and the connection between the transverse tube and the one-way groove realizes a directional flow path for the water sample to enter the storage tank from the outside.

[0010] Preferably, a guide sleeve is slidably installed in the transverse tube, the top ball is installed on the guide sleeve, and a spring is installed on the guide sleeve, and the spring abuts against the inner tube. This elastic guide mechanism realizes the control of the sampling channel, and the pre-tightening force provided by the spring enables the guide sleeve and the top ball combination to maintain a sealed position under normal conditions.

[0011] Preferably, each of the transverse tubes is provided with a through hole, and the guide sleeve is provided with a plurality of vertical grooves, and the through holes and the vertical grooves are in a connected state. This multi-channel fluid transmission system creates an optimized path for water sample entry by aligning the through holes and the vertical grooves.

[0012] Preferably, a plurality of indicator grooves are provided at equal intervals on the side wall of the bidirectional tube, and the indicator grooves between the two bidirectional tubes are close to each other, and a hexagonal groove is provided on the bidirectional tube. This intuitive visual positioning system enables the operator to accurately identify the sampling depth and the status of the device.

[0013] Preferably, the storage tank is provided with two water outlets, and the water outlets are threadedly connected with sealing bolts. This dual water outlet design enables convenient removal of samples and efficient cleaning of equipment, and provides reliable sealing protection through the threaded sealing bolts.

[0014] Preferably, the wire clamping mechanism also includes side grooves symmetrically opened on the inner tube, a side sleeve is slidingly connected to the side groove, a convergence groove is opened in the side sleeve, and a pressure sleeve is fitted in the convergence groove. This precise cable fixing mechanism realizes the adjustment of the pull rope position through the sliding cooperation between the side groove and the side sleeve.

[0015] Preferably, threaded sleeves are respectively installed on both ends of the internal tube, and the threaded sleeves are pressed on the pressure sleeve. This adjustable pressure transmission system controls the force applied to the pressure sleeve through the rotation of the threaded sleeve. The operator can flexibly adjust the fixing strength according to different working environments and rope characteristics, forming a full range of adjustment capabilities from loose to tight.

[0016] Preferably, a plurality of pressure plates are installed at equal intervals on the pressure sleeve, a plurality of the pressure plates are affixed to the convergence groove, and a plurality of the pressure plates are clamped on the side walls of the pull rope. This multi-point distributed clamping mechanism achieves uniform surrounding and clamping of the pull rope through the pressure plates arranged at equal intervals, and the cooperation between the pressure plates and the convergence groove produces a self-locking effect.

[0017] (3) Beneficial effects

[0018] Compared with the existing technology, the present invention provides a groundwater pollution monitoring device with the following beneficial effects:

[0019] This groundwater pollution monitoring equipment adopts an innovative modular split design concept, which solves the difficulties faced by traditional monitoring equipment in remote areas. The core components of the equipment - the middle rope and the middle disk - adopt a flexible connection method, so that the entire system can be compactly coiled when not in operation, significantly reducing the volume and realizing single-person portable transportation. This flexible structural design enables the equipment to easily traverse narrow mountain roads, dense forests or wetland areas, greatly expanding the geographical coverage of groundwater monitoring. It is particularly worth mentioning that the assembly of the equipment does not require professional tools or complex techniques. It adopts an innovative connection mechanism of two-way pipes and spiral grooves. On-site technicians only need to perform a simple rotation operation to firmly connect the storage tank to the middle disk. The entire deployment process can usually be completed within 30 minutes, saving at least 75% of the installation time compared to traditional equipment. This convenient on-site assembly feature not only greatly reduces the labor cost of monitoring operations, but also makes rapid deployment under extreme weather conditions possible, thereby improving the response speed and work efficiency of environmental emergency monitoring.

[0020] The monitoring system has the ability to synchronously sample at multiple depths. Through the combination of multiple intermediate disks and storage tanks set at equal intervals on the intermediate rope, the equipment can simultaneously collect groundwater samples at different depths in a single operation to construct a complete vertical distribution profile of pollutants. This synchronous sampling technology eliminates the data inconsistency caused by time differences in traditional layer-by-layer sampling, making the construction of pollutant migration models more accurate. More importantly, the equipment's rope pull system realizes centralized control of all sampling points. The operator only needs to perform a simple operation through the pull ring to trigger synchronous sampling of all storage tanks, greatly simplifying the sampling process. This innovative design not only improves sampling efficiency, but also ensures the time consistency between samples at different depths, providing a scientific basis for the three-dimensional assessment of groundwater pollution. It is particularly suitable for studying the vertical migration laws and diffusion patterns of pollutants in groundwater bodies, significantly enhancing the scientific value and data quality of groundwater pollution monitoring.

[0021] This groundwater pollution monitoring equipment exhibits wide adaptability and application potential. First, its modular structure allows users to adjust the number and spacing of intermediate disks according to actual needs, easily adapting to various monitoring scenarios from shallow groundwater to deep pressurized water. Second, the equipment's flexible intermediate rope design enables it to adapt to curved wells under various complex terrain conditions, breaking through the application limitations of traditional rigid equipment. Third, the sealed design of the storage tank is not only suitable for conventional pollutant monitoring, but can also be used for sampling and analysis of special indicators such as volatile organic compounds and dissolved gases, greatly expanding the range of monitoring indicators. In addition, through simple modification, the equipment can also be used in geothermal resource exploration, mining area water quality monitoring, agricultural irrigation water quality assessment and other fields, demonstrating strong functional expandability. The lightweight design of the equipment makes it particularly suitable for low-interference monitoring work in ecologically sensitive areas, reducing the impact on the surrounding environment, and conforming to the eco-friendly concept of modern environmental monitoring. This multi-scenario adaptability not only improves the utilization rate and return on investment of the equipment, but also provides technical support for the integration of groundwater monitoring data from different fields, promoting cross-sectoral data sharing and comprehensive analysis.

[0022] This innovative monitoring equipment provides safe, reliable and easy-to-operate technical support for field groundwater monitoring, promotes the transformation of groundwater pollution monitoring from professional technology to popular application, and lays a solid foundation for establishing a broader groundwater environmental monitoring network.

The transverse tube 211 is connected to the one-way groove 26. A guide sleeve 212 is slidably installed in the transverse tube 211, and the top ball 27 is installed on the guide sleeve 212. A spring 213 is installed on the guide sleeve 212, and the spring 213 abuts against the internal tube 210. A through hole 214 is provided on each transverse tube 211, and a plurality of vertical grooves 215 are provided on the guide sleeve 212. The through holes 214 and the vertical grooves 215 are in a connected state. A plurality of indicator grooves 216 are provided at equal intervals on the side wall of the two-way tube 21, and the indicator grooves 216 between the two two-way tubes 21 are close to each other. A hexagonal groove 217 is provided on the two-way tube 21. Two water outlet holes 218 are provided on the storage tank 24, and a sealing bolt 219 is threadedly connected to the water outlet hole 218.

[0038] In view of the need to assemble the monitoring sampling equipment on site in some remote areas, multiple intermediate disks 12 are fixedly installed on the intermediate rope 11, and the distance between the multiple intermediate disks 12 is fixed. Since the intermediate rope 11 is flexible, it can be stored and placed. When assembly is required, first insert the two-way tube 21 into the storage tank 24 at both ends, and then make the untie sleeve 23 slide and connect to the storage tank 24 respectively, and then thread the sealing sleeve 28 into the two-way tube 21 respectively, and the sealing sleeve 28 is pressed against the push spring 29. The thrust of the two push springs 29 makes the two spiral grooves 22 Close to each other, the sealing sleeve 28 is threadedly connected to the storage tank 24. This step can also be performed in advance. When multiple storage tanks 24 need to be fixed, first clamp the two-way tube 21 in the upper and lower end entry grooves 25, and then rotate the two-way tube 21 to increase the distance between the two two-way tubes 21 so that the two-way tubes 21 are respectively pressed against the entry grooves 25. The above operation is performed in all entry grooves 25, thereby ensuring the stability of the fixation, ensuring the distance between the intermediate disks 12 through the intermediate rope 11, and ensuring the limit through multiple two-way tubes 21, thereby ensuring the fixing process.

[0039] The multiple intermediate disks 12 are all fixedly operated. Since the angle of the spiral groove 22 is similar to the angle of the thread, the fixation through the bidirectional tube 21 is equivalent to the self-locking fixation of the thread. If the multiple intermediate disks 12 are all fixedly operated, the multiple intermediate disks 12 will be straightened to ensure that sampling can be carried out at different depths and the monitoring effect is guaranteed.

[0040] The wire clamping mechanism includes a pull rope 31 which is coaxially arranged with the storage tank 24, and a plurality of pull ropes 31 are installed with pull rings 32. The wire clamping mechanism also includes side grooves 33 symmetrically opened on the internal tube 210, and a side sleeve 34 is slidingly connected in the side groove 33. A convergence groove 35 is opened in the side sleeve 34, and a pressure sleeve 36 is fitted in the convergence groove 35. Threaded sleeves 37 are respectively threadedly installed at both ends of the internal tube 210, and the threaded sleeves 37 are pressed on the pressure sleeve 36. A plurality of pressure plates 38 are installed at equal intervals on the pressure sleeve 36, and the plurality of pressure plates 38 are fitted on the convergence groove 35, and the plurality of pressure plates 38 are clamped on the side wall of the pull rope 31.

[0041] When the two-way tube 21 is fixed, the pull rope 31 needs to be fixed at the same time. When each two-way tube 21 is fixed, the three pull ropes 31 are fixed at the same time. By rotating the threaded sleeve 37, the pressure sleeve 36 can be pushed downward so that the pressure plate is pressed into the convergence groove 35, and the pressure plate 38 shrinks along the convergence groove 35, so that the pressure plate 38 is pressed on the side wall of the pull rope 31. Both sides of the internal tube 210 are fixed, and the pull rope 31 and the internal tube 210 are tightened at this time. In a fixed and synchronized state, after the installation is completed, the whole is placed in the groundwater sampling position, and then the pull ring 32 is pulled to pull the three pull ropes 31 synchronously, so that multiple storage tanks 24 move upward synchronously. A one-way groove 26 is opened in the middle position of the storage tank 24, and the top ball 27 is moved upward synchronously. When the top ball 27 hits the unlocking sleeve 23, the seal between the guide sleeve 212 and the one-way groove 26 is unlocked. At this time, groundwater of different depths will flow into the horizontal tube 211 through the one-way groove 26 and the vertical groove 215, and then flow into the storage tank 24 through the through hole 214. At this time, multiple storage tanks 24 of different depths have completed the collection process respectively, and then the pull rope 31 is loosened and the storage tank 24 is reset under the action of multiple push springs 29. At this time, the interference between the top ball 27 and the unlocking sleeve 23 is unlocked, and the spring 213 pushes the guide sleeve 212 against the one-way groove 26, thereby ensuring the sealing process. At this time, the sampling process is completed, and then the multiple storage tanks 24 are taken out as a whole and discharged through the water outlet 218 to complete the pollution detection process.
