It comprehensively utilizes geological theories, exploration techniques, and related scientific methods to obtain geological information and assess geological resources. Groundwater level monitoring devices are specialized equipment used to measure and monitor the depth of groundwater levels. They play an important role in geological exploration and water resource management. Their high precision, stability, and remote monitoring capabilities enable them to provide strong support for the sustainable use of groundwater resources, environmental protection, and geological exploration.

[0003] Existing groundwater level monitoring devices for geological exploration are usually buried directly underground, relying on the support of soil or rock to fix the device. This not only makes maintenance more troublesome, but also makes it difficult to adjust the monitoring depth according to different changes in groundwater level, thus affecting the accuracy of monitoring data.

By setting up a telescopic structure, the depth of the monitoring probe can be automatically adjusted according to changes in groundwater depth, enabling monitoring of groundwater levels at different depths, making it more flexible and applicable.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Geological exploration is a shorthand for geological exploration work. It is mainly based on geological observation and research. According to the requirements of the task, and based on the principle of obtaining more and better geological results in a shorter time and with less workload, necessary technical means or methods are selected, such as surveying and mapping, geophysical exploration, geochemical prospecting, drilling, pit exploration, sampling and testing, geological remote sensing, etc. These means or methods are important bases for the classification of geological exploration qualifications.

[0022] Specifically, the content of geological exploration work includes:

[0023] Basic geological surveys, such as regional geological surveys, geophysical exploration, and geochemical exploration, can systematically grasp information on geological structures, stratigraphic lithology, and geochemical characteristics. This not only helps to delineate prospective mineral exploration areas but also provides a scientific basis for subsequent mineral exploration.

[0024] Mineral exploration: This is an important part of geological exploration, which aims to find and assess mineral resources. Through geological exploration, the distribution, reserves, and quality of mineral resources can be determined, providing basic data for mineral development.

[0025] Geological scientific research: Geological exploration also includes the study of geological phenomena and processes to reveal the structure and evolution of the Earth's interior. These studies are of great significance to the development of geology, the rational development and utilization of Earth's resources, and environmental protection.

[0026] Application areas

[0027] In the mining sector: Geological exploration provides resource security for the development of both metallic and non-metallic mining. By determining the location, reserves, and quality of minerals through exploration, it guides the planning, construction, and mining of mines, improves the utilization efficiency of mineral resources, and reduces mining costs.

[0028] In the field of engineering construction: In the construction of buildings, transportation, water conservancy and other projects, the engineering geological and hydrogeological data provided by geological surveys are important bases for engineering design and construction. For example, before the construction of high-rise buildings, it is necessary to conduct surveys to assess the bearing capacity and stability of the foundation; in the construction of bridges, it is necessary to understand the geological structure and groundwater conditions at the bridge site to ensure the safety of the bridge.

[0029] In the energy sector, geological exploration plays a crucial role in the exploration and development of energy resources such as oil, natural gas, and geothermal energy. Through geophysical and drilling methods, it locates energy resource reservoirs, assesses energy resource reserves and extraction conditions, and provides a scientific basis for energy development and utilization.

[0030] In the field of environmental protection: Geological exploration provides support for environmental geological surveys, geological disaster prevention and control, and water resource protection. By investigating the current status and changes of the geological environment, it assesses the risks of geological disasters and formulates corresponding prevention and control measures. At the same time, through hydrogeological exploration, it protects groundwater resources and prevents groundwater pollution.

[0031] Geological exploration groundwater level monitoring devices are used to measure and record changes in groundwater levels. They can acquire groundwater level data automatically and accurately over a long period of time, providing important basic data for many fields such as geological exploration, water resource management, and engineering construction.

[0032] Application scenarios:

[0033] Groundwater resource management: By monitoring the changing trends of groundwater levels over a long period of time, the sustainable utilization potential of groundwater resources can be assessed, providing a basis for formulating scientific groundwater management strategies.

[0034] Environmental monitoring: Monitoring changes in groundwater levels can reflect the dynamic balance between surface water and groundwater, enabling timely detection and resolution of groundwater pollution and other issues, thus protecting the ecological environment.

[0035] Geological exploration: In geological exploration projects, groundwater level monitoring instruments can be used to monitor changes in groundwater, providing important data support for geological and underground structure research.

[0036] Groundwater level monitoring devices for geological exploration are crucial for acquiring information on groundwater dynamics, assessing water resources, preventing geological disasters, and guiding geological exploration. However, these devices often encounter problems during practical use. Below are some common issues and their causes: 1. Measurement Accuracy Issues: Measurement data contains errors and cannot accurately reflect the true changes in groundwater levels. For example, measured values ​​may deviate from manual measurements or results from other high-precision equipment, or data may fluctuate abnormally within a short period. The main causes may be environmental interference, limitations in the equipment's own accuracy, or improper installation location and method. 2. Data Transmission Issues: Data transmission interruptions, delays, or data loss prevent the timely acquisition of complete water level data during remote monitoring, affecting real-time monitoring of groundwater level changes. The main causes may be communication signal problems, equipment malfunctions, or insufficient power supply. 3. Equipment Durability Issues: The equipment has a short lifespan and is prone to damage. For example, after a period of use, the casing may be damaged, sensors may fail, and mechanical parts may rust or become jammed. The main causes may be harsh working environments and natural wear and tear from long-term operation. 4. Maintenance and Management Issues: High maintenance costs and difficulties in maintenance. Operations such as equipment repair, component replacement, and on-site calibration are complex and time-consuming, affecting the continuity of monitoring work. The main reasons may be inconvenient equipment installation locations, high professional technical requirements, and a lack of effective maintenance plans and spare parts supply.

[0037] Currently, various types of groundwater level monitoring devices for geological exploration are available on the market, aiming to monitor real-time dynamic changes in groundwater levels and provide data support and decision-making basis for water resource management, environmental protection, and disaster prevention and mitigation. For example: 1. Piezoresistive level gauge: This type uses pressure sensors to measure changes in groundwater pressure, thereby determining the groundwater level. The device typically includes pressure-sensitive integrated components as sensor probes. When the probe is fixed at a specific underwater measuring point, the water level can be indirectly measured by measuring the pressure height of the water column above that point and adding it to the elevation of that point. 2. Acoustic level gauge: This type calculates the depth of groundwater by sending and receiving sound waves and the time it takes to receive the echo. This device features a wide measurement range and high accuracy. 3. Float level gauge: This type uses sensors connected to a float to monitor the float's position in the groundwater, thereby determining the groundwater level. The float's rise and fall with the water level drives related mechanical devices or sensors, converting the water level changes into recordable data signals. 4. Groundwater detection radar: Utilizing the propagation characteristics of electromagnetic waves in underground media, it analyzes the distribution of groundwater levels by receiving reflected signals. This equipment can provide high-resolution underground images and is suitable for exploration of complex geological structures.

[0038] Although various types of groundwater level monitoring devices for geological exploration are currently available on the market, some problems still exist in practical use. These include the following issues with the devices mentioned above: 1. Piezoresistive level gauges: Potential problems include sensor accuracy being affected by environmental factors such as temperature and pressure, and sensor aging leading to increased measurement errors over long-term use. 2. Acoustic level gauges: Sound waves may be interfered with by well walls and impurities in the water during propagation, affecting measurement accuracy. Furthermore, the equipment cost is relatively high, and maintenance costs are also high. 3. Float-type level gauges: The float and mechanical device may be damaged due to prolonged immersion in water, leading to inaccurate measurements. Additionally, for deeper wells, the float's rise and fall may be affected by water flow velocity and well wall friction. 4. Groundwater detection radar: The equipment is expensive, complex to operate, and requires professional personnel for operation and analysis. Furthermore, electromagnetic waves may be interfered with by geological structures during underground propagation, affecting the accuracy of the detection results. In summary, different types of groundwater level monitoring devices for geological exploration each have their own working principles and applicable scenarios, but they also have certain problems and limitations. When selecting and using them, it is necessary to comprehensively consider and weigh them based on actual needs and conditions.

[0039] Please see Figure 1 This utility model provides an embodiment of a groundwater level monitoring device for geological exploration, which includes a support component and a monitoring component. The support component is used to install and fix the monitoring component in the corresponding position. The monitoring component, which can be used to monitor the groundwater level at different depths in real time, is fixedly installed in the middle of the upper end of the support component.

[0040] Please see Figure 2 In this embodiment, the support assembly includes a support platform 101, support columns 102, insertion columns 103, and a handle 104. Four sets of support columns 102 for supporting the upper support platform 101 are evenly and fixedly installed around the lower end of the support platform 101. Four sets of insertion columns 103 for inserting into the ground are arranged around the four corners of the upper end of the support platform 101. The insertion columns 103 extend through the upper end of the support platform 101 to the lower end. A handle 104 for controlling the up and down movement of the insertion columns 103 is fixedly connected to the upper end of the insertion columns 103.

[0041] Please see Figures 3-4In this embodiment, the monitoring component includes a water level monitoring module 201, a connecting line 202, a mounting bracket 203, a sleeve column 204, a sliding column 205, a water level sensor head 206, a mounting block 207, a hydraulic rod 208, and a hydraulic cylinder 209. The water level monitoring module 201 is fixedly installed in the upper middle part of the support component. The water level monitoring module 201 is equipped with a sensor module, a signal processing module, a control module, a communication module, a power supply module, and an execution module. The water level monitoring module 201 controls the water level sensor head 206 and the hydraulic cylinder 209 and transmits the monitoring data to a remote terminal in real time. The mounting bracket 203 is fixedly installed in the lower end of the support component. The sleeve column 204 is embedded in the middle of the mounting bracket 203. The inner side of the sleeve column 204 is slidably connected to a sliding rod. The lower end of the column 205 and the water level monitoring module 201 is fixedly connected to a connecting line 202. The connecting line 202 passes through the sleeve column 204 and extends to the lower end of the sliding column 205, where a water level sensor head 206 for real-time sensing of water level changes is fixedly connected. An installation block 207 is fixedly sleeved on the outer side of the lower end of the sliding column 205. Two sets of hydraulic rods 208 for controlling the up and down movement of the sliding column 205 are fixedly installed on the upper end of the installation block 207 in a left-right symmetrical manner. The upper end of the hydraulic rod 208 passes through the lower end of the mounting bracket 203 and extends to the upper end, where a hydraulic cylinder 209 for controlling the up and down movement of the hydraulic rod 208 is fixedly connected. The hydraulic cylinder 209 adjusts the depth of the water level sensor head 206 by controlling the up and down movement of the hydraulic rod 208 to drive the sliding column 205 to slide along the inner wall of the sleeve column 204.

[0042] When working, firstly, according to the structure of the monitoring component, corresponding holes are drilled in the corresponding geological survey ground so that the water level sensor head 206 of the monitoring component can penetrate deep into the groundwater level.

[0043] Then, the monitoring component is installed and fixed in the corresponding position using the support assembly. The support platform 101 is placed so that the support column 102 provides initial support for the support platform 101. Then, the handle 104 is turned to control the insertion column 103 to move downward until the insertion column 103 is firmly inserted into the ground.

[0044] Then, the hydraulic cylinder 209 is controlled by the water level monitoring module 201 to work, so that the hydraulic cylinder 209 controls the hydraulic rod 208 to move, thereby driving the sliding column 205 to slide along the inner wall of the sleeve column 204 until the water level sensing head 206 is adjusted to the appropriate depth.

[0045] During the water level monitoring process, the water level sensor 206 senses the changes in the depth of the groundwater level in real time and transmits the detected data to the water level monitoring module 201 in real time. When the water level drops and the water level sensor 206 can no longer sense water, the water level monitoring module 201 will control the hydraulic cylinder 209 to automatically control the hydraulic rod 208 to move and adjust the position of the water level sensor 206 so that it can automatically adjust its position according to the changes in the depth of the groundwater level to complete the monitoring of groundwater levels at different depths.

[0046] Finally, the water level monitoring module 201 transmits the monitoring data to the remote terminal in real time, so that staff can understand the water level monitoring situation in real time.

[0047] Through the above steps, the monitoring component is installed and fixed on the ground using a support assembly, which facilitates maintenance and adjustment of the monitoring depth. Furthermore, the telescopic structure controlled by hydraulic cylinder 209 automatically adjusts the depth of the monitoring probe according to changes in the groundwater level. This not only improves monitoring flexibility but also facilitates probe maintenance and replacement, making it more adaptable and solving the problem that existing geological exploration groundwater level monitoring devices are typically buried directly underground, relying on the support of soil or rock for fixation. This not only makes maintenance cumbersome but also hinders adjustments to the monitoring depth based on varying groundwater levels, thus affecting the accuracy of the monitoring data.
