Description

Technical Field

[0001] The present application relates to the field of geological exploration technology, and in particular to a groundwater level observation device for geological exploration. Background Art

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

[0003] Existing groundwater level observation devices usually observe by combining measuring probes with sensors. The probes need to go deep into the groundwater area to obtain water level information. In order to adjust the depth of the probe, some devices are supported by telescopic rods or fixed rods, but due to the limited length of the telescopic rods, they cannot meet the needs of large-scale depth adjustment. In addition, some devices use steel cables or measuring ropes to adjust the suspension of the probe, and control the length of the rope manually or mechanically. However, these devices generally have the problem of insufficient adjustment accuracy during use.

[0004] In the process of depth adjustment, existing groundwater level observation devices have difficulty in taking into account the needs of large-scale depth adjustment and short-distance precise adjustment. Specifically, after using steel cables or measuring ropes to achieve large-scale adjustments, there is a lack of effective fine-tuning mechanism, which makes it difficult to accurately control the position of the probe.

[0041] Figure 6 This is a schematic diagram of the interior of a cylinder provided in one embodiment of the present application. Figure 1-Figure 6As shown, an embodiment of the present application provides a groundwater level observation device for geological exploration, including a supporting device 100, an observation component 200 and an adjustment component 300.

[0042] Among them, Figure 1-Figure 3 As shown, the supporting device 100 includes a plurality of legs 110 and a connecting frame 120 . The legs 110 are connected to the connecting frame 120 via hinge components 111 . The connecting frame 120 is provided with an adjusting component 300 and carries an observation component 200 .

[0043] The adjustment assembly 300 includes a spiral adjustment rod 310, a locking mechanism 320, a measuring rope 330 and a rope storage device 340; the top of the spiral adjustment rod 310 vertically penetrates into the connecting frame 120 and is threadedly connected to the bottom end of the connecting frame 120, and a scale mark is set on the outer wall of the spiral adjustment rod 310; the locking mechanism 320 is installed on the spiral adjustment rod 310, and is used to adjust the spiral adjustment rod 310 to a predetermined height and then fix it. Specifically, the locking mechanism 320 uses a locking bolt set on the spiral adjustment rod 310, and 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 continuously approached to the connecting frame 120 until it is tightly attached to the bottom end surface of the connecting frame 120, so that the locking mechanism 320 achieves a good fixing effect. The rope storage device 340 is arranged at the top of the connecting frame 120, and is used to wind and store the measuring rope 330. The rope storage device 340 can be adjusted in height under the rotation control of the spiral adjustment rod 310; one end of the measuring rope 330 is downwardly connected to the observation component 200, and the remaining part of the measuring rope 330 is wound and stored by the rope storage device 340, and is released or retracted according to observation requirements to extend the vertical movement range of the observation component 200.

[0044] like Figure 4 and Figure 5As shown, the observation assembly 200 includes a measuring probe 210, a protective shell 220 and a mechanical fixing assembly 230. The top of the protective shell 220 is suspended by a measuring rope 330 and is located below the connecting frame 120. The measuring probe 210 is installed inside the protective shell 220 through the mechanical fixing assembly 230. The mechanical fixing assembly 230 includes a fixing seat 232 and an elastic connector 231. The fixing seat 232 is arranged at the bottom inside the protective shell 220. The two ends of the elastic connector 231 are respectively connected to the measuring probe 210 and the fixing seat 232, which is used to elastically fix the measuring probe 210 inside the protective shell 220. The embodiment of the present application adopts this structural design, so that the measuring probe 210 is connected to the fixing seat 232 at the bottom of the protective shell 220 through the elastic connector 231. The measuring probe 210 is suspended on the fixing seat 232 by the elastic connector 231, so that it is in a central position inside the protective shell 220 to avoid direct contact with the inner wall of the protective shell 220. This suspended installation design of the measuring probe 210 ensures that the measuring probe 210 can be completely immersed in the water body and prevents the reaction force caused by the water flow directly impacting the inner wall of the protective shell 220 from affecting the measurement accuracy.

[0045] In practical applications, the elastic connector 231 can be made of a high-strength stainless steel spring (such as 304 or 316L stainless steel), which has good corrosion resistance and is suitable for long-term underwater working environments. The spring structure is spiral, and the elastic connection function is achieved through its deformation. One end is fixedly connected to the measuring 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 water flow impact and vibration, thereby ensuring that the measuring probe 210 can maintain a relatively stable position, and the stainless steel spring material has excellent corrosion resistance in an underwater environment and is suitable for long-term use.

[0046] In addition, the elastic connector 231 can also be made of a silicone shock-absorbing gasket, which is made of high-strength silicone (such as industrial-grade silicone, with a hardness in the range of 50-70 Shore A). This material has good elasticity and anti-aging properties. Specifically, the silicone shock-absorbing gasket is round or cylindrical, one end of which is connected to the measuring probe 210 by bonding or mechanical snap-on, and the other end is fixed to the fixing seat 232. The silicone shock-absorbing gasket absorbs impact force through its own elastic deformation. Due to the good elasticity of the silicone material, it can provide a soft buffering support for the measuring probe 210 and reduce the impact of water flow impact on the measuring probe 210. Moreover, the silicone material has good water resistance, temperature resistance and anti-aging properties, and is suitable for long-term underwater use. At the same time, the silicone shock-absorbing gasket is easy to process and replace, which can reduce maintenance costs.

[0047] As the core component of the groundwater level observation device, the selection of the measuring probe 210 should comprehensively consider the observation environment and measurement requirements. Common measuring probes suitable for this device include pressure-type water level probes and ultrasonic water level probes. The pressure-type water level probe measures depth by sensing the water pressure, has the advantages of high precision and strong anti-interference ability, and is suitable for accurate observation of deep water levels; the ultrasonic water level probe realizes non-contact measurement through the principle of ultrasonic reflection, which is suitable for shallow water level observation and clean water environment. Both probes can cooperate well with the protective shell 220 structure of this device to meet the groundwater level monitoring needs of multiple scenarios. However, the specific selection of the measuring probe 210 is not the technical focus of this application. Those skilled in the art can flexibly select the appropriate type of measuring probe according to actual observation needs, environmental conditions and accuracy requirements to achieve the best observation effect.

[0048] The groundwater level observation device for geological exploration provided in the embodiment of the present application, the support device 100 is composed of a plurality of legs 110 and a connecting frame 120, the legs 110 are connected to the connecting frame 120 by hinge parts 111, and the angles of the legs can be adjusted according to different terrains. This structural design makes it easy to achieve stable support for the device on uneven ground, avoiding the influence of tilting or shaking of the device on the measurement accuracy. At the same time, the connecting frame 120 can provide a solid bearing platform for the adjustment component 300 and the observation component 200 to ensure stable operation and use.

[0049] At the same time, the measuring rope 330 and the rope storage device 340 in the adjustment component 300 of this embodiment are used together, so that the observation component 200 can achieve a wide range of depth adjustment in groundwater level observation. The measuring rope 330 is retracted and released through the rope storage device 340, and the vertical position of the protective shell 220 can be adjusted according to actual needs. The spiral adjustment rod 310 provides a precise adjustment function for the height of the rope storage device 340, so as to further fine-tune the penetration depth of the protective shell 220. The embodiment of the present application can avoid the problem of insufficient adjustment caused by the length limitation of the traditional telescopic rod through this clear division of labor adjustment method, and at the same time can improve the accuracy of depth adjustment and provide convenience for operation.

[0050] In addition, the protective shell 220 in the observation component 200 is suspended under the connection frame 120 through the measuring rope 330, and works in conjunction with the adjustment component 300 to flexibly adjust the position. The mechanical fixing component 230 inside the shell fixes the measuring probe 210 inside the shell through the elastic connector 231, which can effectively reduce the vibration caused by water flow disturbance and protect the probe from damage during movement. This arrangement of the measuring probe 210 and the protective shell 220 not only improves the stability of the measurement, but also extends the service life of the device, which is suitable for long-term and multi-environment groundwater level observation needs.

[0051] The groundwater level observation device for geological exploration provided by the embodiment of the present application solves the problem that it is difficult to balance large-scale depth adjustment and short-distance precise adjustment in the prior art through the ingenious design of the adjustment component 300. First, the adjustment component 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 a large-scale depth adjustment is required, the user can release the measuring rope 330 and quickly lower the observation component 200 to the vicinity of the target area. The setting of the rope body storage device 340 enables the measuring rope 330 to be flexibly retracted and released, avoiding the inconvenience and limitation of operation 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 spiral adjustment rod 310, further expanding the scope of action of the measuring rope 330, thereby realizing the preliminary positioning of the large-scale position of the observation component 200.

[0052] After the observation assembly 200 approaches the target position, in order to achieve precise short-distance fine-tuning, the spiral adjustment rod 310 is connected to the bottom of the connecting frame 120 through a threaded structure, and its linear spiral lifting function is used to accurately adjust the position of the protective shell 220. The height adjustment of the spiral adjustment rod 310 has scale marks, and the user can directly observe the adjustment position according to the scale to ensure accuracy. At the same time, the adjustment position can be further fixed by the locking mechanism 320 to prevent the device from being offset due to vibration or external force. This adjustment method not only meets the precise positioning requirements of the target depth, but also avoids the measurement errors caused by inaccurate adjustment in traditional observation devices. By combining the rapid adjustment of the rope storage device 340 and the precise positioning of the spiral adjustment rod 310, the device achieves an organic unity of large-range and short-distance adjustment functions.

[0053] In addition, the multiple adjustment mechanisms of the adjustment component 300 enable the device to adapt to different groundwater level observation scenarios. Whether it is a shallow water level or a deep water level, preliminary positioning can be achieved through the quick release of the measuring rope 330, and then precise adjustment can be achieved through the spiral adjustment of the spiral adjustment rod 310. This dual adjustment method makes up for the defects of the single adjustment mechanism in traditional technology, significantly improves the operating efficiency and measurement accuracy, and at the same time ensures the stability of the measuring 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 foldable structure, the hinge component 111 is a metal hinge, and the leg 110 can be folded around the hinge component 111 to the side of the connection frame 120 .

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

[0056] In some embodiments, a threaded sealing cover 221 is provided on the top of the protective shell 220. The sealing cover 221 is connected to the protective shell 220 by rotation and is provided with a sealing ring to prevent water from penetrating.

[0057] In the above embodiment, a threaded sealing cover 221 is provided on the top of the protective housing 220. The sealing cover 221 is connected to the housing by rotation and is provided with a sealing ring. This method can prevent water from penetrating from the top of the protective housing 220 when the device is not used for water level observation (such as when the device is stored and transported). In addition, the sealing cover 221 can be disassembled and assembled by rotation, which is convenient for the user to open the top of the protective housing 220 when needed. Compared with the fixed cover design, the detachability of the threaded sealing cover 221 is convenient for the user to maintain or replace the measuring probe 210 and other components inside the protective housing, which is particularly suitable for working scenarios where regular inspection or replacement of the measuring probe 210 is required. At the same time, the rotating connection method of the sealing cover 221 is simple and easy to use, and the user can complete the operation without the help of complex tools. This compact structure not only makes the operation of the device more intuitive, but also reduces the impact of the design of the sealing cover 221 on the overall device volume. Optionally, the sealing cover 221 is an annular plate structure so that the hanging connection end of the protective housing 220 for hanging and connecting the measuring rope 330 extends from the central hole of the sealing cover 221.

[0058] The sealing cover 221 of the threaded connection structure is equipped with a sealing ring to provide reliable sealing performance, thereby effectively preventing rain, dust, mud and other foreign substances from entering the interior of the protective shell 220, thereby protecting the internal measuring probe 210 from the external environment, and is particularly suitable for 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 a non-working state, extend the service life of the device, and provide additional protection for the measuring probe in a dusty, humid or highly corrosive environment. When using the groundwater level observation device for geological exploration of the embodiment of the present application to observe the groundwater level, the sealing cover 221 needs to be removed from the top of the protective shell 220 by rotation 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, so that the measuring probe 210 is in direct contact with the water body to collect water level data.

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

[0060] In the above embodiment, a plurality of guide vanes are evenly distributed on the outer wall of the protective shell 220, 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 to bypass the protective shell 220. After the water flow impacting the protective shell 220 is evenly dispersed, the interference of eddy currents and strong impacts of the water flow on the measurement accuracy of the measuring probe 210 is avoided, and it is suitable for groundwater level observation under fast flow or turbulent conditions.

[0061] The guide vane forms a certain inclination angle with the surface of the protective shell 220, which allows the water flow to slide along the surface of the guide vane instead of directly hitting the outer wall of the protective shell 220. The inclined design of the guide vane can reduce the direct impact force of the water flow on the protective shell, which not only improves the guiding efficiency of the guide vane, but also further protects the structural stability of the protective shell 220. This optimized water flow management method reduces the internal vibration of the protective shell 220 caused by the impact of the water flow, thereby providing a more stable working condition for the measuring probe 210.

[0062] In addition, the guide plate is installed on the outer wall of the protective shell 220 through a slot on the surface of the protective shell 220. This structural design makes the guide plate easy to disassemble and maintain. When the guide plate is damaged or needs to be replaced, the user only needs to remove the guide plate from the slot without complicated tools or additional fixing devices. Moreover, the 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, Figure 1 As shown, a rotation operating handle 311 is provided at the bottom end of the spiral adjustment rod 310 , and the rotation operating handle 311 is fixedly connected to the bottom end of the spiral adjustment rod 310 for rotationally adjusting the spiral adjustment rod 310 .

[0064] In the above embodiment, a rotating operating handle 311 is provided at the bottom end of the spiral adjusting rod 310, so that the user can easily adjust the height of the spiral adjusting rod 310 by rotating the rotating operating handle 311, thereby adjusting the distance of the rope body storage device 340 relative to the bottom end height of the connecting frame 120, and further making a slight adjustment in the height position of the observation assembly 200 connected to the measuring rope 330. In this embodiment, the rotating operating handle 311 is fixedly connected to the spiral adjusting rod 310, and when in use, the user rotates the rotating operating handle 311 to avoid the large torque required for directly rotating the spiral adjusting rod 310, which can reduce the difficulty of operation during use. Optionally, the rotating operating handle 311 is evenly provided with anti-slip grooves to increase the friction force, so as to more conveniently and easily realize the screwing operation of the rotating operating handle 311.

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

[0066] In the above embodiment, the bottom of the protective shell 220 is designed with a plurality of drainage holes 222, allowing the water flow inside the protective shell 220 to be quickly discharged through the drainage holes 222, so that after using the device, the water inside the protective shell 220 can be quickly discharged, effectively avoiding the accumulation of water inside the protective shell 220. In addition, in this embodiment, each drainage hole 222 is covered with a detachable filter 223, which can prevent impurities such as mud, sand, and stones from entering the shell through the drainage hole 222. This design not only protects the measuring probe 210 from the influence of external impurities, but also reduces the situation where impurities block the drainage hole. The detachable structure of the detachable filter 223 can be connected in a snap-fit ​​manner so that the detachable filter 223 is snap-fitted and connected in the edge groove of the drainage hole 222. During use, the user can conveniently clean or replace the filter according to the use requirements, thereby improving the use effect and maintenance efficiency of the device.

[0067] In addition, the embodiment of the present application sets a drainage hole 222 at the bottom of the protective shell 220 in combination with the filter net 223. When water enters the protective shell 220, the protective shell 220 can maintain good water circulation while blocking the entry of impurities. This structural design can reduce the impact of water on the bottom of the protective shell 220 while further reducing the shell tilting or uneven force problems caused by the accumulation of impurities entering the protective shell 220. The overall operating stability of the device in different environments is improved, making it relatively better suitable for outdoor scenes with mud or strong water flow.

[0068] In some embodiments, Figure 1 and Figure 3 As shown, an anti-skid pad 112 is provided at the bottom of the leg 110 .

[0069] In this embodiment, by providing an anti-skid pad 112 at the bottom of the leg 110, the stability of the device during use can be enhanced. The anti-skid pad 112 can provide additional friction when the device is placed on a slippery ground, reduce the possibility of the leg 110 slipping, and avoid the influence of the tilt or movement of the device on the measurement results. At the same time, the anti-skid pad 112 is optionally made of a flexible material, such as rubber or silicone, so that it can better adapt to different ground forms, further improving the adaptability of the device in complex terrain.

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

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

[0072] Moreover, the aluminum alloy material is not only light but also has high strength. After the legs 110 are unfolded, they can withstand greater pressure, and the connecting frame 120 can better bear the weight of the observation assembly 200. At the same time, the surface of the aluminum alloy is usually anodized, so it has excellent corrosion resistance. During use, it can resist the influence of moisture, rain and other corrosive substances in the field environment, thereby extending the service life of the device, and is particularly suitable for use in environments with many water bodies or high humidity.

[0073] In addition, aluminum alloy materials have good machinability, and can easily realize complex geometric design and processing. Aluminum alloy materials have high machining accuracy and can meet the strict matching requirements between components, making the device structure stable and operating smoothly. At the same time, aluminum alloy materials are easy to recycle, which not only meets performance requirements but also reflects environmental advantages.

[0074] In some embodiments, Figure 1-Figure 3 As shown, the connecting frame 120 includes a frame body 121 and a gripping portion 122. The frame body 121 is a cylindrical structure. The upper sides of the frame body 121 are provided with gripping portions 122 for manual lifting. The gripping portions 122 are made of metal rods and are connected to the frame body 121 by welding or screwing.

[0075] In the above embodiment, the connection frame 120 adopts a structure consisting of a frame body 121 and a gripping portion 122. The upper sides of the frame body 121 are provided with gripping portions 122 for manual lifting. This embodiment makes the device more convenient during transportation and handling through the provision of the gripping portions 122. When in use, the user can lift the device with one hand or two hands through the gripping portions 122 without directly contacting the frame body 121, thereby improving the practicality and operating 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 adjustment component 300 and the observation component 200 to improve the structural strength and stability of the connection frame 120. Moreover, the frame body 121 with a cylindrical structure design also optimizes the overall layout and reduces the safety hazards caused by sharp edges.

[0077] The grip 122 is made of a metal rod and is connected to the frame body 121 by welding or screwing. This connection method not only ensures a high-strength connection between the grip 122 and the frame body 121, but also has good durability and is not prone to loosening or damage when the device is frequently lifted. The welding method ensures the firmness of the integration, while the screw fixing method facilitates later maintenance or replacement, providing users with more flexible usage options.

[0078] In some embodiments, a mounting groove is provided on the frame body 121, and a cylinder 341 is provided on the frame body 121 through the mounting groove. The rope storage device 340 is arranged inside the cylinder 341, and the cylinder 341 is a hollow cylindrical structure with an opening at the bottom so that the measuring rope 330 can pass downward. The top of the spiral adjustment rod 310 abuts against the bottom of the cylinder 341 and the spiral adjustment rod 310 can drive the cylinder 341 to move vertically when rotating. Since the top of the spiral adjustment rod 310 abuts against the bottom of the cylinder 341, the spiral adjustment rod 310 is rotated in use to move up and down along the thread direction. This vertical linear movement of the spiral adjustment rod 310 can accurately drive the cylinder 341 to the desired height position. Since the rotation of the spiral adjustment rod 341 is proportional to the vertical displacement, its fine-tuning accuracy is determined by the pitch of the thread, so that fine height adjustment can be achieved to meet the precise control requirements of the penetration depth. During application, the vertical movement of the cylinder 341 directly affects the position of the rope storage device 340, thereby changing the height of the support point of the measuring rope 330. Through this adjustment, the initial release point of the measuring rope 330 also changes accordingly. After the protective shell 220 penetrates the groundwater level in a large range, the final position of the protective shell 220 and the measuring probe 210 can be accurately positioned by fine-tuning the cylinder 341. This adjustment method avoids the deviation caused by adjusting the length of the measuring rope 330 alone, and improves 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 spiral adjustment rod 310. At this time, the spiral adjustment rod drives the cylinder 341 to make fine adjustments in the vertical position, so as to ensure that the protective shell 220 and the measuring probe 210 inside it remain stable at the predetermined depth. After the fine adjustment is completed, the spiral adjustment rod 310 is fixed by the locking mechanism 320 to prevent the position of the cylinder 341 from shifting. This embodiment can not only assist in adjusting the penetration depth of the protective shell 220 through the cooperation between the spiral adjustment rod 310 and the cylinder 341, but also improve the flexibility and accuracy of the measurement depth adjustment. Compared with the length control relying solely on the measuring rope 330, this dual adjustment mechanism makes the device more adaptable to different groundwater level measurement scenarios and improves the reliability of data measurement.

[0080] Alternatively, if Figure 3 As shown, 2-4 guide bosses 345 connected to the inner side wall of the mounting groove of the frame body 121 are evenly arranged on the outer wall of the cylinder 341 in a circumferential direction, and a slide groove that slides with the guide bosses 345 is arranged on the inner side wall of the mounting groove of the frame body 121. These guide bosses 345 slide with the slide groove on the inner side wall of the mounting groove of the frame body 121 to form a stable vertical guide structure. The guide bosses 345 can ensure that the cylinder 341 remains stable when moving in the vertical direction, avoid lateral shaking or deviation, and enhance 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 adjustment rod 310. The top end of the spiral adjustment rod 310 is placed in the abutment sleeve and abuts against the inner top wall of the abutment sleeve. The bottom end surface of the cylinder 341 is provided with a guide hole 344 for the spiral adjustment rod 310 to be threadedly connected. In this embodiment, an abutment sleeve is provided at the bottom end of the cylinder 341, and the abutment sleeve is used to accommodate the top end of the spiral adjustment rod 310, so that the spiral adjustment rod 310 can stably abut against the inner top wall of the abutment sleeve and the spiral adjustment rod 310 can rotate in the abutment sleeve. This structural design not only ensures that the force transmission process of the spiral adjustment rod 310 is stable and reliable, but also further limits the lateral displacement of the spiral adjustment rod 310 through the guide hole 344 at the bottom end of the cylinder 341, and the guide hole 344 can provide precise thread fit, thereby enhancing the synchronization between the rotation drive of the spiral adjustment rod 310 and the vertical movement of the cylinder 341.

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

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

[0083] In the above embodiment, the frame body 121 is provided with a mounting groove to install 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 adopts a hollow cylindrical design, and provides a collection and release channel for the measuring rope 330 through the bottom opening. This method optimizes the use of the space of the frame body 121, avoids the rope storage device 340 occupying the external space, thereby improving the overall integration and portability of the device, and is suitable for the use requirements of limited space in the field environment.

[0084] At the same time, in this embodiment, the rope storage device 340 includes a reel 342 and an operating hand wheel 343 with a locking mechanism. The reel 342 is set in the cylinder 341 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 retraction and release process of the measuring rope 330 smoother, and can flexibly adjust the length of the measuring rope 330 according to the observation depth requirements, and can also prevent the measuring rope 330 from accidentally loosening due to external forces. The operating hand wheel 343 with a locking mechanism is installed on the outer wall of the cylinder 341, which is easy to operate and adjust, and further improves the reliability of the positioning of the measuring rope 330, thereby ensuring the stability of the measuring probe during work.

[0085] In addition, the cylinder 341 adopts a hollow cylindrical structure, which can provide comprehensive protection for the rope storage device 340 and avoid the direct impact 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 enter and exit smoothly. In addition, the setting of the installation groove can facilitate the disassembly and fixation of the cylinder 341 in the frame body 121, thereby improving the convenience of using the rope storage device 340.

[0086] The use process of the groundwater level observation device for geological exploration in the embodiment of the present application is as follows:

[0087] Before starting the groundwater level observation, the device is first unfolded and set at a suitable observation position. By unfolding the legs 110 and adjusting their angles, the anti-skid pads 112 at the bottom of the legs are in close contact with the ground, thereby ensuring the stability of the device on uneven terrain. Subsequently, the height of the cylinder 341 is adjusted using the rotating operating handle 311 of the spiral adjustment rod 310 so that the observation assembly 200 of the device can reach the initial observation position. After the adjustment is completed, the spiral adjustment rod 310 is fixed by the locking mechanism 320 so that the height of the cylinder 341 is stable.

[0088] The rope storage device 340 is used to control the retraction and release of the measuring rope 330, and the protective shell 220 with the measuring probe 210 inside is gradually lowered to a predetermined position according to the groundwater level depth requirement. In this process, the operating hand wheel 343 with a locking mechanism can be used to lock the reel 342 to prevent the measuring rope 330 from accidentally sliding, ensuring that the protective shell 220 stably reaches the target water level area. At the same time, the guide plate on the outer wall of the protective shell 220 guides the water flow to bypass 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 groundwater level data. The drainage hole 222 at the bottom of the protective shell 220 and the filter 223 covering it ensure that 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 brought back to the initial position by retracting the measuring rope 330, and the sealing cover 221 of the protective shell 330 is threadedly connected after cleaning the device, completing the entire process of groundwater level observation. This operation process is efficient and convenient, and can be well applied to complex underground environments.
