Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of geological exploration, and particularly relates to a groundwater level observation device for geological exploration. BACKGROUND

[0002] Groundwater level observation is an important link in geological exploration and is widely used in resource development, engineering construction and environmental monitoring fields. The dynamic change of groundwater level directly affects the geological environment assessment, engineering design and development and utilization of groundwater resources, and therefore accurate and stable groundwater level observation technology is of great significance to geological engineering and water resources management.

[0003] The existing groundwater level observation device usually observes in a manner of combining a measuring probe with a sensor. The probe needs to be deeply inserted into the groundwater area to obtain water level information. In order to realize depth adjustment of the probe, some devices support through telescopic rods or fixed rods. However, due to the limited length of the telescopic rod, it cannot meet the demand of large-range depth adjustment. In addition, some devices use steel cables or measuring ropes to realize suspension adjustment of the probe, and control the length of the rope body through manual or mechanical methods. However, these devices generally have the problem of insufficient adjustment accuracy in use.

[0004] In the depth adjustment process of the existing groundwater level observation device, it is difficult to meet the demand of large-range depth adjustment and short-distance accurate adjustment. Specifically, after realizing large-range adjustment by using a steel cable or a measuring rope, there is a lack of effective fine adjustment mechanism, which makes it difficult to accurately control the position of the probe.

[0041] Figure 6 The internal schematic diagram of the barrel provided by an embodiment of the present application is shown in the figure. Figures 1-6As shown, the embodiment of the present application provides a groundwater level observation device for geological exploration, which comprises a supporting device 100, an observation assembly 200 and an adjusting assembly 300.

[0042] Wherein, as Figures 1-3 The supporting device 100 comprises a plurality of supporting legs 110 and a connecting frame 120, the supporting legs 110 are connected with the connecting frame 120 through hinged parts 111, the adjusting assembly 300 is arranged on the connecting frame 120 and the observation assembly 200 is carried on the connecting frame 120.

[0043] The adjusting assembly 300 comprises a screw adjusting rod 310, a locking mechanism 320, a measuring rope 330 and a rope body storage device 340; the top end of the screw adjusting rod 310 is vertically upwardly inserted into the connecting frame 120 and is threadedly connected with the bottom end of the connecting frame 120, and a scale mark is arranged on the outer wall of the screw adjusting rod 310; the locking mechanism 320 is installed on the screw adjusting rod 310 and is used for fixing the screw adjusting rod 310 after being adjusted to a predetermined height. Specifically, the locking mechanism 320 adopts a locking bolt arranged on the screw adjusting rod 310, the locking mechanism 320 is located below the bottom end of the connecting frame 120, by rotating the locking mechanism 320, the locking mechanism 320 is constantly close to the connecting frame 120 until being tightly attached to the bottom end surface of the connecting frame 120, so that the locking mechanism 320 achieves good fixing effect. The rope body storage device 340 is arranged on the top of the connecting frame 120 and is used for winding and storing the measuring rope 330, the rope body storage device 340 can be adjusted in height under the rotation control of the screw adjusting rod 310; one end of the measuring rope 330 is downwardly connected to the observation assembly 200, the rest of the measuring rope 330 is wound and stored through the rope body storage device 340, and is released or retracted according to the observation requirement to extend the vertical movement range of the observation assembly 200.

[0044] As Figure 4 and Figure 5As shown, the observation assembly 200 includes a measurement probe 210, a protective shell 220, and a mechanical fixing assembly 230. The measurement probe 210 is mounted inside the protective shell 220 through the mechanical fixing assembly 230. The mechanical fixing assembly 230 includes a fixing seat 232 and an elastic connecting piece 231. The fixing seat 232 is arranged at the bottom inside the protective shell 220. The two ends of the elastic connecting piece 231 are connected to the measurement probe 210 and the fixing seat 232, respectively, for elastically fixing the measurement probe 210 inside the protective shell 220. In the embodiment of the present application, the measurement probe 210 is connected to the fixing seat 232 at the bottom inside the protective shell 220 through the elastic connecting piece 231. The measurement probe 210 is suspended above the fixing seat 232 by the elastic connecting piece 231, so that it is in a central position inside the protective shell 220 and avoids direct contact with the inner wall of the protective shell 220. The suspension mounting design of the measurement probe 210 ensures that the measurement probe 210 can be completely immersed in the water body and avoids the influence of the reaction force caused by the direct impact of the water flow on the inner wall of the protective shell 220 on the measurement precision.

[0045] In actual application, the elastic connecting piece 231 can be made of high-strength stainless steel spring (such as 304 or 316L stainless steel). Such material has good corrosion resistance and is suitable for long-term underwater working environment. The spring structure is in a spiral shape and realizes the elastic connection function through its deformation. One end is fixedly connected to the measurement probe 210, and the other end is connected to the fixing seat 232 to provide reliable suspension support. In use, the elastic deformation of the spring can absorb the impact of the water flow and vibration, so as to ensure that the measurement probe 210 can maintain a relatively stable position. Moreover, the stainless steel spring material has excellent corrosion resistance in underwater environment and is suitable for long-term use.

[0046] In addition, the elastic connecting piece 231 can also be made of a silica gel shock pad. The silica gel shock pad is made of high-strength silica gel (such as industrial-grade silica gel with a hardness in the range of 50-70 Shore A). Such material has good elasticity and anti-aging performance. Specifically, the silica gel shock pad is in a circular or columnar shape. One end is connected to the measurement probe 210 through adhesion or mechanical buckle, and the other end is fixed on the fixing seat 232. The silica gel shock pad absorbs the impact force through its elastic deformation. Since the silica gel material has good elasticity, it can provide soft buffer support for the measurement probe 210 and reduce the influence of the water flow impact on the measurement probe 210. Moreover, the silica gel material has good water resistance, temperature resistance, and anti-aging performance, and is suitable for long-term underwater use. At the same time, the silica gel shock pad is easy to process and replace, which can reduce the maintenance cost.

[0047] The measurement probe 210 is the core component of the underground water level observation device, and its selection should consider the observation environment and measurement requirements. Common measurement probes suitable for the device include pressure type water level probes and ultrasonic water level probes. The pressure type water level probe measures the depth by sensing the water pressure, has high precision and strong anti-interference ability, and is suitable for accurate observation of deep water level. The ultrasonic water level probe realizes non-contact measurement through ultrasonic reflection principle, and is suitable for shallow water level observation and clean water environment. Both types of probes can be well matched with the protective shell 220 structure of the device, meeting the underground water level monitoring requirements in multiple scenarios. However, the specific selection of the measurement probe 210 is not the technical focus of the present application, and those skilled in the art can flexibly select the appropriate measurement probe type according to the actual observation requirements, environmental conditions and precision requirements to achieve the best observation effect.

[0048] The underground water level observation device for geological exploration provided in the embodiments of the present application is composed of a plurality of supporting legs 110 and a connecting frame 120. The supporting legs 110 are connected to the connecting frame 120 through hinge components 111 and can adjust the leg angle according to different terrains. This structural design makes it easy to achieve stable support on uneven ground and avoids the influence of device inclination or shaking on measurement accuracy. At the same time, the connecting frame 120 can provide a stable load-bearing platform for the adjusting assembly 300 and the observation assembly 200 to ensure stable operation and use.

[0049] At the same time, the measurement rope 330 in the adjusting assembly 300 and the rope body storage device 340 in the embodiments of the present application are used in cooperation, so that the observation assembly 200 can achieve large-range depth adjustment in underground water level observation. The measurement rope 330 is retracted and extended through the rope body storage device 340, which can adjust the vertical position of the protective shell 220 according to actual requirements. The screw adjusting rod 310 provides precise adjustment of the height of the rope body storage device 340, thereby further fine-tuning the depth of the protective shell 220. The embodiments of the present application can avoid the insufficient adjustment problem caused by the length limitation of the traditional telescopic rod through this clear division of labor adjustment method, and can improve the accuracy of depth adjustment and provide convenience for operation.

[0050] In addition, the protective shell 220 in the observation assembly 200 is suspended below the connecting frame 120 through the measurement rope 330 and works in cooperation with the adjusting assembly 300 to adjust the position flexibly. The mechanical fixing assembly 230 inside the shell fixes the measurement probe 210 inside the shell through the elastic connecting piece 231, which not only effectively reduces the vibration caused by water flow disturbance, but also protects the probe from damage during movement. This arrangement of the measurement probe 210 and the protective shell 220 not only improves the stability of measurement, but also prolongs the service life of the device, which is suitable for long-term and multi-environment underground water level observation requirements.

[0051] The underground water level observation device for geological exploration provided by the embodiments of the present application solves the problem that it is difficult to balance wide-range depth adjustment and short-distance accurate adjustment in the prior art through the ingenious design of the adjusting assembly 300. First, the adjusting assembly 300 includes a measuring rope 330 and a rope body storage device 340. One end of the measuring rope 330 is connected to the protective shell 220, and the other part is wound or released through the rope body storage device 340. When wide-range depth adjustment is needed, the user can quickly lower the observation assembly 200 to the vicinity of the target area by releasing the measuring rope 330. The setting of the rope body storage device 340 enables the measuring rope 330 to be flexibly wound and released, avoiding the inconvenience and limitation caused by a single fixed length. At the same time, the height of the rope body storage device 340 can be adjusted by rotating the screw adjusting rod 310, further expanding the range of the measuring rope 330, thereby realizing the preliminary positioning of the observation assembly 200 in a wide range.

[0052] After the observation assembly 200 approaches the target position, in order to realize accurate short-distance fine adjustment, the screw adjusting rod 310 is connected to the bottom end of the connecting frame 120 through a threaded structure, and the linear screw lifting function is used to accurately adjust the position of the protective shell 220. The height adjustment of the screw adjusting rod 310 has a scale mark, and the user can directly observe the adjustment position according to the scale to ensure accuracy, and the adjustment position can be further fixed by the locking mechanism 320 to avoid position deviation caused by vibration or external force. This adjustment method not only meets the accurate positioning requirements of the target depth, but also avoids the measurement errors caused by inaccurate adjustment in traditional observation devices. Through the combination of the rapid adjustment of the rope body storage device 340 and the accurate positioning of the screw adjusting rod 310, the device realizes the organic unification of wide-range and short-distance adjustment functions.

[0053] In addition, the multiple adjustment mechanisms of the adjusting assembly 300 enable the device to adapt to different underground water level observation scenarios. Whether it is a shallow water level or a deep water level, preliminary positioning can be realized through the rapid release of the measuring rope 330, and accurate adjustment can be realized through the screw adjustment of the screw adjusting rod 310. This dual adjustment method compensates for the defects of the single adjustment mechanism in traditional technology, significantly improves the operation efficiency and measurement accuracy, and at the same time ensures the stability of the measurement probe 210 and the reliability of the protective shell 220. The overall design not only improves the flexibility of the device, but also optimizes the convenience of user operation, and has strong practicality.

[0054] In some embodiments, the leg 110 is a folding structure, and the hinge component 111 is a metal hinge. The leg 110 can be folded around the hinge component 111 to the side of the connecting frame 120.

[0055] In the above embodiment, the support leg 110 adopts a folding structure and is connected with the connecting frame 120 through the hinge part 111, so that the support leg 110 can rotate around the hinge part 111 and close to the side of the connecting frame 120, thereby reducing the occupied space of the device when not in use, improving the portability of the device, and facilitating the user to carry and transport the device in the field geological exploration. At the same time, the folded structure is more compact and suitable for storage in limited storage space. The metal hinge is used as the hinge part 111, which has high strength and wear resistance and is not easy to loosen or damage during multiple folding and unfolding, thereby better guaranteeing the long-term use requirement of the device in complex terrain conditions in the field.

[0056] In some embodiments, the top of the protective shell 220 is provided with a threaded sealing cover 221, which is connected with the protective shell 220 in a rotating manner and is provided with a sealing ring to prevent water from penetrating.

[0057] In the above embodiment, the top of the protective shell 220 is provided with a threaded sealing cover 221, which is connected with the protective shell 220 in a rotating manner and is provided with a sealing ring to prevent water from penetrating.

[0058] The sealing cover 221 of the threaded connection structure is provided with a sealing ring to provide reliable sealing performance, thereby effectively preventing external substances such as rainwater, dust, and silt from entering the inside of the protective shell 220, thereby protecting the internal measurement probe 210 from the external environment, and is particularly suitable for use in the transportation and storage stages. In addition, the sealing cover 221 can also reduce the wear of the internal components of the protective shell 220 in the non-working state, prolong the service life of the device, and at the same time, provide additional protection for the measurement probe in a dusty, humid, or highly corrosive environment. When using the underground water level observation device for geological exploration in the embodiment of the present application to observe the underground water level, the sealing cover 221 needs to be removed from the top of the protective shell 220 in a rotating manner to ensure the connectivity between the inside of the protective shell 220 and the external water body. After removing the sealing cover 220, the top of the protective shell 220 remains open, and the water body can freely enter and exit the protective shell 220 through the top inlet and the bottom inlet, thereby allowing the measurement probe 210 to directly contact the water body and collect water level data.

[0059] In some embodiments, the outer wall of the protective shell 220 is uniformly distributed with guide vanes (not shown in the figure), which form an inclination angle with the surface of the protective shell 220 for guiding the water flow and reducing the impact on the protective shell 220. The guide vanes are installed on the outer wall of the protective shell 220 through the insertion slots on the surface of the protective shell 220. Optionally, the guide vanes form an inclination angle of 10° to 30° with the surface of the protective shell 220, and the guide vanes are arranged in a spiral along the outer wall of the protective shell 220.

[0060] In the above embodiment, the outer wall of the protective shell 220 is uniformly distributed with multiple guide vanes, and each guide vane forms an inclination angle with the surface of the protective shell 220. This structural design can effectively change the direction of the water flow and guide the water flow around the protective shell 220. After the water flow impacting the protective shell 220 is uniformly dispersed, the interference of vortex and strong water flow impact on the measurement accuracy of the measurement probe 210 is avoided, and the device is suitable for underground water level observation under rapid flow or turbulent conditions.

[0061] The guide vanes form an inclination angle with the surface of the protective shell 220, which allows the water flow to slide along the surface of the guide vanes instead of directly impacting the outer wall of the protective shell 220. This inclined design of the guide vanes can reduce the direct impact force of the water flow on the protective shell, not only improving the guiding efficiency of the guide vanes, but also further protecting the structural stability of the protective shell 220 itself. This optimized water flow management method reduces the internal vibration of the protective shell 220 caused by water flow impact, thereby providing more stable working conditions for the measurement probe 210.

[0062] In addition, the guide vanes are installed on the outer wall of the protective shell 220 through the insertion slots on the surface of the protective shell 220. This structure design makes the guide vanes easy to disassemble and maintain. When the guide vanes are damaged or need to be replaced, the user only needs to remove the guide vanes from the insertion slots, without the need for complex tools or additional fixing devices. Moreover, the insertion slot installation method also reduces the processing complexity of the outer wall of the protective shell 220, which helps to improve the overall maintainability and service life of the device.

[0063] In some embodiments, as shown in Figure 1 The bottom end of the screw adjusting rod 310 is provided with a rotating operation handle 311, which is fixedly connected with the bottom end of the screw adjusting rod 310 and used for rotating adjustment of the screw adjusting rod 310.

[0064] In the above embodiment, the rotating operation handle 311 is arranged at the bottom end of the screw adjusting rod 310, so that the user can easily adjust the height of the screw adjusting rod 310 by rotating the rotating operation handle 311, thereby adjusting the distance between the rope storage device 340 and the bottom end of the connecting frame 120, and further adjusting the height position of the observation assembly 200 connected with the measuring rope 330. In this embodiment, the rotating operation handle 311 is fixedly connected with the screw adjusting rod 310, and the large torque required for directly rotating the screw adjusting rod 310 is avoided by rotating the rotating operation handle 311, which can reduce the operation difficulty in use. Optionally, the rotating operation handle 311 is uniformly provided with anti-slip patterns outside to increase the friction and facilitate the rotation operation of the rotating operation handle 311.

[0065] In some embodiments, as shown in Figure 3 The bottom of the protective shell 220 is provided with a plurality of drainage holes 222 as the inlet of the water body at the bottom of the protective shell 220, which is used in combination with the inlet at the top of the protective shell 220 after the sealing cover 221 is removed, so that the water body can freely enter and exit the protective shell 220, thereby enabling the measuring probe 210 to directly contact with the water body and collect water level data. The drainage holes 222 are covered with detachable filter screens 223 to prevent impurities from entering the inside of the shell.

[0066] In the above embodiment, the bottom of the protective shell 220 is designed with multiple drainage holes 222, allowing water inside the protective shell 220 to quickly drain through the drainage holes 222. This allows the water inside the protective shell 220 to be quickly drained after use, effectively preventing the accumulation of water inside the protective shell 220. In addition, the embodiment covers each drainage hole 222 with a detachable filter screen 223, which can prevent impurities such as sand and stones from entering the interior of the shell through the drainage holes 222. This design not only protects the measurement probe 210 from external impurities, but also reduces the likelihood of impurities clogging the drainage holes. The detachable structure of the detachable filter screen 223 can be connected by clamping, so that the detachable filter screen 223 is clamped and connected in the edge groove of the drainage hole 222. During use, users can easily clean or replace the filter screen according to their needs, thereby improving the use effect and maintenance efficiency of the device.

[0067] In addition, the embodiment of the present application combines the setting of the drainage hole 222 at the bottom end of the protective shell 220 with the filter screen 223. When water enters the interior of the protective shell 220, the interior of the protective shell 220 can maintain good water circulation while blocking the entry of impurities. This structural design not only reduces the impact of water on the bottom of the protective shell 220, but also further reduces the problem of uneven force or tilting of the shell caused by the accumulation of impurities inside the protective shell 220. This improves the operational stability of the device in different environments, making it more suitable for use in outdoor scenes with sand or strong water flow.

[0068] In some embodiments, as shown in Figure 1 and Figure 3 The bottom of the leg 110 is provided with a non-slip pad 112.

[0069] In the present embodiment, the non-slip pad 112 is provided at the bottom of the leg 110 to enhance the stability of the device during use. The non-slip pad 112 can provide additional friction when the device is placed on a slippery surface, reducing the likelihood of the leg 110 slipping and avoiding the impact of device tilting or movement on measurement results. Meanwhile, the non-slip pad 112 is made of flexible materials such as rubber or silicone, which can better adapt to different ground shapes and further improve the adaptability of the device in complex terrain.

[0070] In some embodiments, the leg 110 and the connecting frame 120 are made of aluminum alloy material.

[0071] The support legs 110 and the connecting frame 120 are made of aluminum alloy material. Compared with the traditional steel material design, this light material can significantly reduce the overall weight of the device, thereby improving the portability of the device. In field geological exploration, the equipment often needs to be frequently carried and moved. The lightweight characteristics of aluminum alloy reduce the operating burden of the user and facilitate the transportation and storage of the device, especially suitable for scenarios that require rapid deployment.

[0072] Moreover, the aluminum alloy material is not only light, but also has high strength. After the support legs 110 are unfolded and supported, they can withstand a large pressure, and the connecting frame 120 can better bear the weight of the observation assembly 200. At the same time, the aluminum alloy surface is usually subjected to anodizing treatment, so it has excellent corrosion resistance and can resist the influence of moisture, rain and other corrosive substances in the field environment during use, thereby prolonging the service life of the device, especially suitable for use in environments with a lot of water or high humidity.

[0073] In addition, the aluminum alloy material has good processability and can easily realize complex geometric design and processing. Moreover, the aluminum alloy material has high processing precision and can meet the strict fitting requirements between parts, so that the device structure is stable and the operation is smooth. At the same time, the aluminum alloy material is easy to recycle, which not only meets the performance requirements but also embodies the environmental protection advantage.

[0074] In some embodiments, as shown in Figures 1-3 The connecting frame 120 includes a frame body 121 and a holding portion 122. The frame body 121 has a cylindrical structure, and the upper portion of the frame body 121 is provided with the holding portion 122 for manual lifting. The holding portion 122 is made of a metal rod and is connected to the frame body 121 by welding or screwing.

[0075] In the above embodiment, the connecting frame 120 adopts the structure composed of the frame body 121 and the holding portion 122. The upper portion of the frame body 121 is provided with the holding portion 122 for manual lifting. In this embodiment, the device is more convenient to transport and carry during use. The user can lift the device by the holding portion 122 with one hand or both hands, without directly contacting the frame body 121, thereby improving the practicality and operation comfort of the device.

[0076] At the same time, the frame body 121 in this embodiment adopts a cylindrical structure design, which can better distribute the load pressure from the adjusting assembly 300 and the observation assembly 200, thereby improving the structural strength and stability of the connecting frame 120. Moreover, the cylindrical structure design of the frame body 121 also optimizes the overall layout and reduces the safety hazards caused by sharp edges.

[0077] The holding part 122 is made of a metal rod and is connected to the frame body 121 by welding or screw fixation. This connection not only ensures a high-strength combination between the holding part 122 and the frame body 121, but also has good durability and is not easy to loosen or damage when the device is frequently lifted. The welding method ensures the firmness of the integration, and the screw fixation method is convenient for later maintenance or replacement, providing users with more flexible use options.

[0078] In some embodiments, the frame body 121 is provided with a mounting groove, and the frame body 121 is provided with a cylinder 341 through the mounting groove. The rope storage device 340 is arranged inside the cylinder 341, which is a hollow cylindrical structure with an open bottom to allow the measuring rope 330 to pass downward. The top end of the screw adjusting rod 310 abuts the bottom end of the cylinder 341, and the screw adjusting rod 310 can drive the cylinder 341 to move vertically when rotated. Since the top end of the screw adjusting rod 310 abuts the bottom end of the cylinder 341, the screw adjusting rod 310 moves up and down along the thread direction by rotating during use. The linear movement of the screw adjusting rod 310 in the vertical direction can accurately drive the cylinder 341 to the desired height position. Since the rotation of the screw adjusting rod 341 is directly proportional to the vertical displacement, the fine adjustment accuracy is determined by the pitch of the thread, so subtle height adjustment can be achieved to meet the precise control requirements of the probe depth. During application, the vertical movement of the cylinder 341 directly affects the position of the rope storage device 340, thereby changing the support point height of the measuring rope 330. Through this adjustment, the initial release point of the measuring rope 330 also changes. After the protective shell 220 is widely probed into the groundwater level, fine positioning of the protective shell 220 and the measuring probe 210 can be achieved by fine adjustment of the cylinder 341. This adjustment method avoids the deviation caused by adjusting the length of the measuring rope 330, improving the accuracy of the measurement depth control.

[0079] In groundwater level observation, when the protective shell 220 with the measuring probe 210 inside reaches the target depth through the measuring rope 330, the operator can further rotate the screw adjusting rod 310. At this time, the screw adjusting rod drives the cylinder 341 to make subtle adjustments in the vertical position, thereby ensuring that the protective shell 220 and the measuring probe 210 inside it remain stable at the predetermined depth. After fine adjustment is completed, the screw adjusting rod 310 is fixed by the locking mechanism 320 to prevent the cylinder 341 from shifting position. This embodiment cooperates the screw adjusting rod 310 with the cylinder 341, which not only assists in adjusting the probe depth of the protective shell 220, but also improves the flexibility and accuracy of the measurement depth adjustment. Compared with simply relying on the length control of the measuring rope 330, this double adjustment mechanism makes the device more adaptable to different groundwater level measurement scenarios and improves the reliability of data measurement.

[0080] Optionally, such as Figure 3 As shown, 2-4 guide bosses 345 are evenly arranged circumferentially on the outer wall of the cylinder 341, which are vertically slidably connected to the inner sidewall of the mounting groove of the frame body 121. The inner sidewall of the mounting groove of the frame body 121 is provided with sliding grooves that slidably engage with the guide bosses 345. These guide bosses 345 and the sliding grooves on the inner sidewall of the mounting groove of the frame body 121 form a stable vertical guiding structure. The guide bosses 345 ensure that the cylinder 341 remains stable when moving vertically, avoiding lateral swaying or deviation, and simultaneously enhancing the positioning accuracy between the cylinder 341 and the frame body 121. The bottom end of the cylinder 341 is also provided with an abutment sleeve that contacts the top end of the spiral adjusting rod 310. The top end of the spiral adjusting rod 310 is placed in the abutment sleeve and abuts against the inner top wall of the abutment sleeve. A guide hole 344 is provided on the bottom end face of the cylinder 341 for threaded connection of the spiral adjusting rod 310. In this embodiment, an abutment sleeve is provided at the bottom end of the cylinder 341. The abutment sleeve is used to accommodate the top end of the spiral adjusting rod 310, so that the spiral adjusting rod 310 can stably abut against the inner top wall of the abutment sleeve and can rotate within the abutment sleeve. This structural design not only ensures the stable and reliable force transmission process of the spiral adjusting rod 310, but also further restricts the lateral displacement of the spiral adjusting rod 310 through the guide hole 344 at the bottom end of the cylinder 341. Moreover, the guide hole 344 can provide a precise threaded fit, thereby enhancing the synchronization between the rotation drive of the spiral adjusting rod 310 and the vertical movement of the cylinder 341.

[0081] In the above embodiments, the guide boss 345, the slide groove, the abutment sleeve and the guide hole 344 work together to form a structure that integrates positioning, guidance and force transmission, so that the cylinder 341 can maintain high-precision vertical movement during adjustment and effectively avoid deviation or jamming caused by external force or use.

[0082] Among them, such as Figure 1 , Figure 2 and Figure 6 As shown, the rope storage device 340 includes a spool 342 and an operating handwheel 343 with a locking mechanism. The spool 342 is installed at the center of the inside of the cylinder 341 for winding the measuring rope 330. The operating handwheel 343 is installed on the outer wall of the cylinder 341 for controlling the rotation and stopping of the spool 342.

[0083] In the above embodiment, the frame body 121 is provided with a mounting groove to mount the cylinder 341, so that the rope storage device 340 is arranged inside the cylinder 341, thereby forming a compact and reasonable structure. The cylinder 341 is designed as a hollow cylinder, and provides a winding and unwinding channel for the measuring rope 330 through the bottom opening. In this way, the space of the frame body 121 is optimized, and the rope storage device 340 does not occupy external space, thereby improving the overall integration and portability of the device, and meeting the use requirements of limited space in field environment.

[0084] Meanwhile, in the present embodiment, the rope storage device 340 includes a reel 342 and an operating hand wheel 343 with a locking mechanism. The reel 342 arranged in the cylinder 341 is used to wind the measuring rope 330, and the rotation of the reel is precisely controlled by the operating hand wheel 343. This design makes the winding and unwinding process of the measuring rope 330 more stable, and can flexibly adjust the length of the measuring rope 330 according to the observation depth requirement, while avoiding accidental loosening of the measuring rope 330 due to external force. The operating hand wheel 343 with a locking mechanism is installed on the outer wall of the cylinder 341, which is convenient for operation and adjustment, and further improves the reliability of the positioning of the measuring rope 330, thereby ensuring the stability of the measuring probe in operation.

[0085] In addition, the cylinder 341 adopts a hollow cylindrical structure, which can provide comprehensive protection for the rope storage device 340, avoiding the direct influence of the external environment on the reel 342 and the operating hand wheel 343. The bottom opening design of the cylinder 341 allows the measuring rope 330 to smoothly enter and exit. In addition, the installation groove can facilitate the disassembly and fixation of the cylinder 341 in the frame body 121, thereby improving the use convenience of the rope storage device 340.

[0086] The use process of the geological exploration underground water level observation device according to the present application is as follows:

[0087] Before starting the underground water level observation, first unfold the device and set it at a suitable observation position. By unfolding the supporting legs 110 and adjusting the angle thereof, the anti-skid pads 112 at the bottom of the supporting legs 110 are tightly contacted with the ground, thereby ensuring the stability of the device on uneven terrain. Then, the rotating operation handle 311 of the screw adjusting rod 310 is used to adjust the height of the cylinder 341, so that the observation assembly 200 of the device can reach the preliminary observation position. After adjustment, the screw adjusting rod 310 is fixed by the locking mechanism 320, so that the height of the cylinder 341 is stable.

[0088] The winding and unwinding of the measuring rope 330 is controlled by the rope storage device 340, and the protective shell 220 with the measuring probe 210 inside is gradually lowered to the predetermined position according to the requirement of the underground water level. During this process, the operating hand wheel 343 with the locking mechanism can be used to lock the reel 342, preventing the measuring rope 330 from sliding accidentally, and ensuring that the protective shell 220 reaches the target water level area stably. At the same time, the guide vanes on the outer wall of the protective shell 220 guide the water flow around the protective shell 220, reducing the direct interference of the water flow on the measuring probe 210 inside the protective shell 220.

[0089] When the measuring probe 210 reaches the target water level, the measuring probe 210 starts to collect the underground water level data. The drain hole 222 at the bottom of the protective shell 220 and the filter screen 223 covering it ensure that the water flows in while blocking impurities from entering, thereby ensuring that the measuring probe 210 obtains accurate water level data. After the measurement is completed, the protective shell 330 is pulled back to the initial position by retracting the measuring rope 330, and the sealing cover 221 of the protective shell 330 is screwed on after cleaning the device, completing the entire process of underground water level observation. This operation process is efficient and convenient, and can be well applied to complex underground environments.
