Description

Technical Field

[0001] The present application relates to the field of groundwater monitoring, and in particular to a multi-parameter groundwater depth determination device. Background Art

[0002] In the field of groundwater monitoring, obtaining accurate and comprehensive groundwater parameters is key to scientifically assessing groundwater resource status. To achieve this goal, multiple core parameters, such as water level, temperature, conductivity, and pH, must be measured simultaneously. Therefore, the monitoring process often requires the simultaneous deployment of specialized equipment such as water level meters, thermometers, conductivity meters, and pH meters.

[0003] In related technologies, on-site sampling generally relies on manual operation. Technicians not only need to frequently switch various instruments and equipment, but also need to manually transcribe and record large amounts of data. This process is not only time-consuming and labor-intensive, but also has a high risk of human recording errors.

[0004] Furthermore, in terms of fixed-depth measurement technology, traditional devices mostly rely on manual experience to control the measurement depth, lacking precise depth positioning and real-time feedback mechanisms. They only provide rough estimates based on the rope scale. This makes it difficult to accurately determine the probe's true stratigraphic position when monitoring in areas with complex geological structures, such as underground caves and fractured areas. Due to the hidden and complex nature of the underground environment, changes in the stratigraphic structure can cause the rope to become tangled or deflected during transmission, further reducing the accuracy of depth measurements. This makes it difficult to accurately measure groundwater parameters at different depths, significantly increasing measurement errors and potentially leading to misjudgment of information and errors in fixed-depth sampling. Summary of the Invention

[0005] The present application provides a multi-parameter groundwater depth determination device, the purpose of which is to avoid the tedious operation of frequent equipment switching in traditional technologies by integrating multiple monitoring modules. Technicians no longer need to repeatedly debug equipment and calibrate parameters. The time for a single group of monitoring tasks can be greatly shortened, and it can meet the needs of large-scale and high-frequency groundwater monitoring. At the same time, the automated data collection and transmission mechanism replaces manual transcription and record keeping, avoiding data recording errors caused by human factors, improving the authenticity and integrity of the data, and thus providing effective support for actual production work such as groundwater pollution prevention and control and ecological restoration.

[0006] This application provides a multi-parameter groundwater depth determination device, which adopts the following technical solutions:

[0007] A multi-parameter groundwater depth determination device includes an integrated template, on which are respectively installed a water level meter, a thermometer, a conductivity meter, a pH meter and a GPS positioning device. The water level meter, thermometer, conductivity meter, pH meter and GPS positioning device are integrated into the integrated template using a modular design. A main control unit is installed on the integrated template, and the main control unit and the water level meter, thermometer, conductivity meter, pH meter and GPS positioning device are connected via a corresponding data transmission bus. A cable encoder and a fixed depth float are also installed on the integrated template, and the fixed depth float is lowered through a corresponding guide rod.

[0008] By employing this technical solution, the cable encoder accurately records the length of the lowered cable, effectively ensuring the accuracy of the depth-determining float lowered to the specified depth. This allows for groundwater sampling at a specific depth using the depth-determining float. The main control unit is connected to the guide rod used to lower the depth-determining float via a data transmission bus. This guide rod ensures the stable lowering of the depth-determining float to the specified depth in the well.

[0009] These devices on the integrated template are equipped with a main control unit that automatically controls the coordinated operation of each monitoring module and sampling mechanism according to preset instructions, achieving continuous and timed data detection. A cable is connected to a cable encoder. When the fixed-depth float reaches the specified depth, the electric pump on the integrated template activates and pumps water for sampling. Once data collection is complete, it is transmitted to the main control unit for subsequent analysis and processing.

[0010] This setting method, by integrating multiple monitoring modules, avoids the tedious operation of frequent equipment switching in traditional technologies. Technicians no longer need to repeatedly debug equipment and calibrate parameters. The time for a single set of monitoring tasks can be greatly shortened, which can meet the needs of large-scale and high-frequency groundwater monitoring. The high-precision depth positioning system overcomes the defects of traditional measurement technology that relies on manual experience and rough estimates. Even in areas with complex geological structures, the depth measurement error can be controlled within 0.5 cm. Multiple sensors are measured simultaneously to provide reliable data support for scientific assessment of groundwater resource conditions.

[0011] Automated data collection and transmission replaces manual transcription, eliminating data recording errors caused by human error and improving data authenticity and integrity. Furthermore, the device's modular design facilitates future maintenance and upgrades, reducing equipment maintenance costs. Real-time monitoring data alerts and real-time comparisons with quality standards provide strong technical support for water resource management, groundwater pollution prevention and control, and ecological restoration, promoting the rational development and effective protection of groundwater resources. The integrated structure is suitable for a variety of field environments, and its superior modular design ensures durability and ease of maintenance.

[0012] Preferably, a peristaltic pump is installed on the integrated template to provide power during the cable lowering process.

[0013] By adopting the above technical solution, the peristaltic pump is composed of a driver, a pump head and an elastic hose, and the peristaltic pump is used to further achieve precise lowering of the cable.

[0014] Preferably, a first connecting piece is provided between the cable and the guide rod.

[0015] By adopting the above technical solution, the first connecting member can effectively connect the cable and the guide rod while also effectively improving the sealing between the guide rod and the cable, which is beneficial to avoid problems with the sealing between the cable and the guide rod that affect the stability of the connection between the cable and the guide rod.

[0016] Preferably, a sealing groove is provided on the guide rod at the position of the first connecting piece along its circumference, and second connecting pieces are integrally formed at the upper and lower ends of the first connecting piece close to the guide rod, and both second connecting pieces are embedded in the sealing groove.

[0017] By adopting the above technical solution, the first connecting member and the second connecting member can effectively improve the stability of the connection between the cable and the guide rod while also being able to perform double sealing on the inner and outer sides of the guide rod, which is beneficial to improving the sealing between the cable and the guide rod, and effectively increasing the waterproof performance of the guide rod at the position of the first connecting member, and effectively avoiding the groundwater from seeping into the space between the first connecting member and the guide rod during the lowering process of the cable and the guide rod, affecting the stability of the connection between the guide rod and the first connecting member. The more stable the connection between the guide rod and the first connecting member, the more stable the connection between the cable and the guide rod.

[0018] The traditional connection method between the cable and the guide rod is to place a conventional connector on the guide rod and connect it between the cable and the guide rod. The traditional connector only serves to connect the cable and the guide rod. When the cable and the guide rod are submerged for a long time, once groundwater seeps between the connector and the guide rod, it will affect the stability of the connection between the guide rod and the connector. As more and more water seeps in, in serious cases, the position of the connector on the guide rod will shift. When the position of the connector on the guide rod shifts, it will affect the accuracy of the cable lowered along the guide rod, thereby causing a certain error in the depth of groundwater sampling. This accumulation of measurement errors not only affects the reliability of monitoring data, but also may obscure the potential changes in the groundwater environment, thereby misleading scientific decision-making in important areas such as water resources management and geological disaster warning, and cannot provide effective support for actual production work such as groundwater pollution prevention and control and ecological restoration.

[0019] The second connector effectively increases the connection area between the first connector and the guide rod, thereby facilitating improved stability of the connection between the first connector and the guide rod, and thereby facilitating improved stability of the connection between the cable and the guide rod. Furthermore, the second connector can improve the sealing between the first connector and the guide rod and effectively prevent groundwater from seeping between the first connector and the guide rod, thereby further ensuring the stability of the connection between the guide rod and the cable.

[0020] Preferably, connecting grooves are opened along the circumference of the upper and lower sides of the sealing groove, and the two second connecting members at the upper and lower ends of the first connecting member correspond one-to-one to the two connecting grooves opened at the upper and lower ends of the sealing groove respectively, and the second connecting member includes a first plate body and a second plate body, the first plate body is horizontally arranged, the first plate body and the first connecting member are connected on the side close to the guide rod, the second plate body is vertically arranged, the second plate body is upwardly inserted into the connecting groove, and the first plate body and the second plate body are overall in an "L" shape.

[0021] By adopting the above technical solution, specifically, when the first plate body and the second plate body are installed, the first plate body and the groove wall of the connecting groove are tightly attached to each other, and the second plate body is inserted into the connecting groove. The first plate body and the second plate body can effectively improve the sealing between the first connecting member and the guide rod, and effectively prevent groundwater from seeping into the guide rod. Moreover, the first plate body and the second plate body form an "L"-shaped structure. Even if groundwater seeps into between the first connecting member and the guide rod, it will not fall into the inside of the guide rod. The groundwater will fall on the first plate body. After the groundwater sampling is completed, the first connecting member and the second connecting member can be removed from the guide rod for water removal. Then, the first connecting member and the second connecting member will not allow groundwater to seep into the guide rod during the sampling process, which is beneficial to ensure the accuracy of the groundwater sampling process and the sampling accuracy.

[0022] Preferably, the second plate body is slidably mounted on the first plate body in the vertical direction, a sliding groove is provided on one side of the second plate body in the vertical direction, the groove wall of the connecting groove is integrally connected with a slider, and the slider is slidably mounted in the sliding groove.

[0023] By adopting the above technical solution, the purpose of doing so is to facilitate sliding the second plate out of the connecting groove, and then after the groundwater sampling is completed, the first connecting member and the second connecting member can be conveniently and efficiently removed from the guide rod for maintenance.

[0024] During groundwater sampling, the second plate slides into the corresponding connecting groove, which limits the second plate's position and effectively ensures the stability of the connection between the second plate and the guide rod. When sampling is completed and the first and second connecting members need to be removed for maintenance, the second plate slides out of the corresponding connecting groove, and the first and second connecting members are then removed for maintenance.

[0025] Preferably, a driving component for driving the second plate to slide in a vertical direction is additionally provided in the guide rod located in the sealing groove.

[0026] By adopting the above technical solution, the driving assembly is used to realize the sliding of the second plate on the first plate.

[0027] Preferably, the driving assembly includes a movable rod and two connecting rods, the movable rod is arranged horizontally, and a through groove for the movable rod to move is opened on the guide rod located in the sealing groove in the horizontal direction, and the movable rod slides in the through groove in the horizontal direction, and the two connecting rods are spaced apart in the upper and lower parts, and the two connecting rods are arranged horizontally, and the two connecting rods correspond to the two second plates respectively;

[0028] Wedge blocks are integrally formed on the upper and lower sides of one end of the movable rod close to the connecting rod, and the end of the connecting rod close to the wedge block is wedge-shaped. The connecting rod and the wedge block are wedge-shaped and matched, and the end of the connecting rod away from the movable rod is movably connected to the corresponding second plate body;

[0029] A return spring is installed between the connecting rod and the groove wall of the sealing groove along the vertical direction.

[0030] By adopting the above technical solution, during the groundwater sampling process, the movable rod slides toward the direction close to the connecting rod. During this process, the two connecting rods slide toward the direction away from each other. In the process of moving away from each other, the two connecting rods drive the corresponding second plate body to slide toward the direction close to the corresponding connecting groove until the second plate body is inserted into the corresponding connecting groove.

[0031] When sampling is completed and the first connecting member and the second connecting member need to be taken out for maintenance, the movable rod slides in the direction away from the connecting rod. During this process, the two connecting rods slide in the direction toward each other, and drive the two second plates to slide in the direction away from the corresponding connecting grooves until the second plates slide out of the corresponding connecting grooves.

[0032] The return spring is used to assist the connecting rod in sliding and returning in the vertical direction, and at the same time, corresponding support is provided to the connecting rod.

[0033] Preferably, the connecting rod and the corresponding second plate are connected by magnetic attraction.

[0034] By adopting the above technical solution, the magnetic connection method facilitates the connection and disconnection between the connecting rod and the second plate, thereby making the installation and removal of the first connecting member and the second connecting member more efficient.

[0035] Preferably, a knob is installed on the outside of the guide rod and a driving gear is installed inside the guide rod. The knob and the driving gear are connected by a corresponding rotating shaft. The bottom of the driving gear is engaged with a driving rack in the horizontal direction, and the driving rack is connected to the bottom of the movable rod.

[0036] By adopting the above technical solution, when driving the movable rod, the knob is turned, and the driving gear is driven to rotate synchronously by the knob. During the rotation process, the driving gear engages with the driving rack, driving the driving rack to slide, and the driving rack is used to drive the movable rod to slide in the horizontal direction.

[0037] In summary, this application includes at least one of the following beneficial technical effects:

[0038] 1. These devices on the integrated template are equipped with a main control unit that automatically controls the coordinated operation of each monitoring module and sampling mechanism according to preset instructions, achieving continuous and timed data detection. A cable is connected to a cable encoder. When the fixed-depth float reaches the specified depth, the electric pump on the integrated template activates and pumps water for sampling. Once data collection is complete, it is transmitted to the main control unit for subsequent analysis and processing.

[0039] This setup, by integrating multiple monitoring modules, avoids the tedious operation of frequent equipment switching required by traditional technologies. Technicians no longer need to repeatedly debug equipment and calibrate parameters, significantly shortening the time required for a single monitoring task and meeting the needs of large-scale, high-frequency groundwater monitoring. The high-precision depth positioning system overcomes the shortcomings of traditional measurement technologies that rely on manual experience and rough estimates. Even in areas with complex geological structures, it can control depth measurement errors to within 0.5 cm. Simultaneous measurement by multiple sensors provides reliable data support for scientific assessment of groundwater resource conditions.

[0040] 2. The first connector and the second connector effectively improve the stability of the connection between the cable and the guide rod while also providing a double seal on both the inside and outside of the guide rod, thereby improving the sealing between the cable and the guide rod and effectively increasing the waterproof performance of the guide rod at the position of the first connector. This effectively prevents groundwater from seeping between the first connector and the guide rod during the lowering process of the cable and the guide rod, thereby affecting the stability of the connection between the guide rod and the first connector. The more stable the connection between the guide rod and the first connector, the more stable the connection between the cable and the guide rod.

[0041] 3. During groundwater sampling, the second plate slides into the corresponding connecting slot along the direction of the first plate's chute, using the connecting slot to limit the second plate's position, effectively ensuring the stability of the connection between the second plate and the guide rod. When sampling is completed and the first and second connecting members need to be removed for maintenance, the second plate slides out of the corresponding connecting slot along the direction of the first plate's chute, and then the first and second connecting members are removed for maintenance.

[0048] The following is combined with Figure 1 -Attached Figure 5 , further details of this application are given.

[0049] Example:

[0050] The embodiment of the present application discloses a multi-parameter groundwater depth determination device, which is mainly used for fixed-depth sampling and analysis of groundwater at different depths in groundwater wells, thereby providing effective support for actual production work such as groundwater pollution prevention and control and ecological restoration.

[0051] Reference Figure 1 and Figure 2The system comprises an integrated template 1, which is rectangular in shape and is equipped with a water level gauge, thermometer, conductivity meter, pH meter, and GPS positioning device. These detection devices are integrated into the integrated template 1 using a modular design. A main control unit 2 for controlling these devices is also installed on the integrated template 1. The main control unit 2 is connected to these devices via a corresponding data transmission bus to effectively achieve multi-parameter synchronous monitoring and real-time data aggregation between these devices.

[0052] At the same time, refer to Figure 1 and Figure 2 For fixed-depth sampling, the integrated template 1 is also equipped with a cable encoder 3 and a fixed-depth float 4. The cable encoder 3 accurately records the length of the lowering cable, effectively ensuring the accuracy of the lowering of the fixed-depth float 4 to the specified depth. This allows for fixed-depth sampling of groundwater using the fixed-depth float 4. The main control unit 2 is connected to a guide rod 5 for lowering the fixed-depth float 4 via a data transmission bus. This guide rod 5 ensures the stable lowering of the fixed-depth float 4 to the specified depth in the underground well.

[0053] Further, refer to Figure 1 and Figure 2 A peristaltic pump 6 is installed on the integrated template 1 to provide power during the cable lowering process. The peristaltic pump 6 is composed of a driver, a pump head and an elastic hose. The peristaltic pump 6 is used to further achieve precise lowering of the cable.

[0054] These devices on the integrated template 1 are equipped with a main control unit 2, which automatically controls the coordinated operation of each monitoring module and sampling mechanism according to preset instructions, achieving continuous and timed data detection. A cable is connected to a cable encoder 3. When the fixed depth float 4 reaches the specified depth, the electric pump on the integrated template 1 activates and pumps water for sampling. Once data collection is complete, it is transmitted to the main control unit 2 for subsequent analysis and processing.

[0055] This setting method, by integrating multiple monitoring modules, avoids the tedious operation of frequent equipment switching in traditional technologies. Technicians no longer need to repeatedly debug equipment and calibrate parameters. The time for a single set of monitoring tasks can be greatly shortened, which can meet the needs of large-scale and high-frequency groundwater monitoring. The high-precision depth positioning system overcomes the defects of traditional measurement technology that relies on manual experience and rough estimates. Even in areas with complex geological structures, the depth measurement error can be controlled within 0.5 cm. Multiple sensors are measured simultaneously to provide reliable data support for scientific assessment of groundwater resource conditions.

[0056] Automated data collection and transmission replaces manual transcription, eliminating data recording errors caused by human error and improving data authenticity and integrity. Furthermore, the device's modular design facilitates future maintenance and upgrades, reducing equipment maintenance costs. Real-time monitoring data alerts and real-time comparisons with quality standards provide strong technical support for water resource management, groundwater pollution prevention and control, and ecological restoration, promoting the rational development and effective protection of groundwater resources. The integrated structure is suitable for a variety of field environments, and its superior modular design ensures durability and ease of maintenance.

[0057] Further, refer to Figure 1 and Figure 2 A first connecting piece 7 is provided between the cable and the guide rod 5. The first connecting piece 7 can effectively connect the cable and the guide rod 5 while also effectively improving the sealing between the guide rod 5 and the cable, thereby helping to avoid problems with the sealing between the cable and the guide rod 5 that affect the stability of the connection between the cable and the guide rod 5.

[0058] Further, refer to Figure 2 and Figure 3 A sealing groove 8 is provided along the circumference of the guide rod 5 at the position of the first connecting piece 7. Second connecting pieces 9 are integrally formed at the upper and lower ends of the first connecting piece 7 close to the guide rod 5. Both second connecting pieces 9 are embedded in the sealing groove 8 on the circumference of the guide rod 5. The first connecting piece 7 and the second connecting piece 9 can effectively improve the stability of the connection between the cable and the guide rod 5 while also performing double sealing on the inner and outer sides of the guide rod 5, which is beneficial to improving the sealing between the cable and the guide rod 5 and effectively increasing the waterproof performance of the guide rod 5 at the position of the first connecting piece 7, effectively preventing groundwater from seeping into the space between the first connecting piece 7 and the guide rod 5 during the lowering process of the cable and the guide rod 5, affecting the stability of the connection between the guide rod 5 and the first connecting piece 7. The more stable the connection between the guide rod 5 and the first connecting piece 7, the more stable the connection between the cable and the guide rod 5.

[0059] The traditional connection method between the cable and the guide rod 5 is to place a conventional connector on the guide rod 5 and connect the cable and the guide rod 5. The traditional connector only serves to connect the cable and the guide rod 5. When the cable and the guide rod 5 are submerged for a long time, once groundwater seeps between the connector and the guide rod 5, it will affect the stability of the connection between the guide rod 5 and the connector. As more and more water seeps in, in serious cases, the position of the connector on the guide rod 5 will be displaced. When the position of the connector on the guide rod 5 is displaced, it will affect the accuracy of the cable lowered along the guide rod 5, thereby causing a certain error in the depth of groundwater sampling. This accumulation of measurement errors not only affects the reliability of monitoring data, but also may obscure the potential change trend of the groundwater environment, thereby misleading scientific decision-making in important areas such as water resources management and geological disaster warning, and cannot provide effective support for actual production work such as groundwater pollution prevention and control and ecological restoration.

[0060] In the embodiment of the present application, the second connector 9 is used to effectively increase the connection area between the first connector 7 and the guide rod 5, thereby facilitating improved stability of the connection between the first connector 7 and the guide rod 5, and further facilitating improved stability of the connection between the cable and the guide rod 5. Furthermore, the second connector 9 can be used to improve the sealing between the first connector 7 and the guide rod 5 and effectively prevent groundwater from seeping between the first connector 7 and the guide rod 5, thereby further ensuring the stability of the connection between the guide rod 5 and the cable.

[0061] Specifically, refer to Figure 2 、 Figure 3 as well as Figure 4 , both upper and lower sides of the sealing groove 8 are provided with connecting grooves 10 along the circumference thereof, and the two second connecting members 9 at the upper and lower ends of the first connecting member 7 correspond one-to-one to the two connecting grooves 10 provided at the upper and lower ends of the sealing groove 8. The second connecting member 9 includes a first plate body 91 and a second plate body 92 that are connected as one piece. The first plate body 91 is arranged horizontally, and the first plate body 91 is connected to the side of the first connecting member 7 close to the guide rod 5. The second plate body 92 is arranged vertically, and the second plate body 92 is inserted upward into the connecting groove 10. The first plate body 91 and the second plate body 92 are in an "L"-shaped structure as a whole. Inserting the second plate body 92 into the connecting groove 10 effectively increases the stability of the connection between the second connecting member 9 and the guide rod 5.

[0062] Specifically, when the first plate 91 and the second plate 92 are installed, the first plate 91 and the groove wall of the connecting groove 10 are tightly attached to each other, and the second plate 92 is inserted into the connecting groove 10. The first plate 91 and the second plate 92 can effectively improve the sealing between the first connecting piece 7 and the guide rod 5, and effectively prevent groundwater from seeping into the guide rod 5. Moreover, the first plate 91 and the second plate 92 form an "L"-shaped structure. Even if groundwater seeps into between the first connecting piece 7 and the guide rod 5, it will not fall into the inside of the guide rod 5. The groundwater will fall on the first plate 91. After the groundwater sampling is completed, the first connecting piece 7 and the second connecting piece 9 can be removed from the guide rod 5 for water removal. Then, the first connecting piece 7 and the second connecting piece 9 will not allow groundwater to seep into the guide rod 5 during the sampling process, which is beneficial to ensure the accuracy of the groundwater sampling process and the sampling precision.

[0063] Specifically, a corresponding sliding groove is provided on one side of the second plate 92 in the vertical direction, and a slider is integrally connected to the groove wall of the connecting groove 10. When the second plate 92 slides into the connecting groove 10, the corresponding sliding groove and slider guide the sliding of the second plate 92, thereby facilitating improved sliding stability of the second plate 92 within the connecting groove 10. After the second plate 92 slides into the connecting groove 10, the first plate 91 and the bottom of the connecting groove 10 are in close contact, thereby effectively ensuring the sealing of the sealing groove 8.

[0064] At the same time, the purpose of doing so is to facilitate sliding the second plate 92 out of the connecting groove 10, and then after the groundwater sampling is completed, the first connecting member 7 and the second connecting member 9 can be conveniently and efficiently removed from the guide rod 5 for maintenance.

[0065] During groundwater sampling, the second plate 92 slides into the corresponding connection groove 10, and the connection groove 10 is used to limit the second plate 92 to effectively ensure the stability of the connection between the second plate 92 and the guide rod 5. When sampling is completed and the first connecting member 7 and the second connecting member 9 need to be removed for maintenance, the second plate 92 slides out of the corresponding connection groove 10, and then the first connecting member 7 and the second connecting member 9 are removed for maintenance.

[0066] Specifically, a driving assembly for driving the second plate 92 to slide in the vertical direction is added to the guide rod 5 located in the sealing groove 8 , and the driving assembly is used to realize the sliding of the second plate 92 on the first plate 91 .

[0067] Specifically, refer to Figure 3 、 Figure 4 as well as Figure 5The drive assembly includes a movable rod 11 and two connecting rods 12. The movable rod 11 is horizontally disposed. A through slot is horizontally formed through the guide rod 5 located within the sealing groove 8, allowing the movable rod 11 to slide horizontally within the through slot. The two connecting rods 12 are spaced apart vertically and are horizontally disposed, corresponding one-to-one with the two second plates 92.

[0068] Reference Figure 3 、 Figure 4 as well as Figure 5 The movable rod 11 is integrally formed with wedge blocks 13 on the upper and lower sides near one end of the connecting rod 12. The end of the connecting rod 12 near the wedge block 13 is wedge-shaped. The connecting rod 12 and the wedge block 13 are wedge-shaped. The connecting rod 12 is movably connected between the end away from the movable rod 11 and the corresponding second plate body 92.

[0069] Specifically, during the groundwater sampling process, the movable rod 11 slides toward the direction close to the connecting rod 12. During this process, the two connecting rods 12 slide toward the direction away from each other. In the process of moving away from each other, the two connecting rods 12 drive the corresponding second plate body 92 to slide toward the direction close to the corresponding connecting groove 10 until the second plate body 92 is inserted into the corresponding connecting groove 10.

[0070] When sampling is completed and the first connecting member 7 and the second connecting member 9 need to be taken out for maintenance, the movable rod 11 slides in the direction away from the connecting rod 12. During this process, the two connecting rods 12 slide in the direction toward each other and drive the two second plates 92 to slide in the direction away from the corresponding connecting grooves 10 until the second plates 92 slide out of the corresponding connecting grooves 10.

[0071] Reference Figure 4 and Figure 5 A return spring 14 is installed between the connecting rod 12 and the groove wall of the sealing groove 8 in the vertical direction. The return spring 14 assists the connecting rod 12 to slide and return in the vertical direction, and at the same time provides corresponding support for the connecting rod 12.

[0072] In this embodiment, a magnetic connection method is adopted between the connecting rod 12 and the corresponding second plate body 92. The magnetic connection method facilitates the connection and disconnection between the connecting rod 12 and the second plate body 92, thereby making the installation and disassembly of the first connecting member 7 and the second connecting member 9 more efficient.

[0073] Further, refer to Figure 3 、 Figure 4 as well as Figure 5A knob 15 is mounted on the outside of the guide rod 5, and a drive gear 16 is mounted inside the guide rod 5. The knob 15 and the drive gear 16 are connected by a corresponding rotating shaft. The bottom of the drive gear 16 is horizontally meshed with a drive rack 17, which is connected to the bottom of the movable rod 11. Specifically, when driving the movable rod 11, the knob 15 is rotated, which drives the drive gear 16 to rotate synchronously. During the rotation process, the drive gear 16 meshes with the drive rack 17, causing the drive rack 17 to slide, and the drive rack 17 drives the movable rod 11 to slide horizontally.

[0074] The implementation principle of the multi-parameter groundwater depth determination device in the embodiment of the present application is as follows:

[0075] These devices on the integrated template 1 are equipped with a main control unit 2, which automatically controls the coordinated operation of each monitoring module and sampling mechanism according to preset instructions, achieving continuous and timed data detection. A cable is connected to a cable encoder 3. When the fixed depth float 4 reaches the specified depth, the electric pump on the integrated template 1 activates and pumps water for sampling. Once data collection is complete, it is transmitted to the main control unit 2 for subsequent analysis and processing.

[0076] This setting method, by integrating multiple monitoring modules, avoids the tedious operation of frequent equipment switching in traditional technologies. Technicians no longer need to repeatedly debug equipment and calibrate parameters. The time for a single set of monitoring tasks can be greatly shortened, which can meet the needs of large-scale and high-frequency groundwater monitoring. The high-precision depth positioning system overcomes the defects of traditional measurement technology that relies on manual experience and rough estimates. Even in areas with complex geological structures, the depth measurement error can be controlled within 0.5 cm. Multiple sensors are measured simultaneously to provide reliable data support for scientific assessment of groundwater resource conditions.
