Description

Technical Field

[0001] This utility model relates to the field of drilling engineering technology, specifically to an intelligent probe device. Background Technology

[0002] Accurate monitoring of hydrogeological parameters is a crucial foundation for research on groundwater dynamics, mineral resource exploration, geothermal resource development, and environmental geological surveys. Obtaining in-situ, real-time hydrogeological data from boreholes is of paramount importance for resource assessment, disaster early warning, and environmental protection.

[0003] Currently, the monitoring of hydrogeological parameters in boreholes mainly adopts the method of "traditional sensors + cable transmission". This means that single-function sensors (such as pressure level gauges or temperature probes) are lowered into the borehole through cables, and the signals are transmitted to the data acquisition instrument on the surface through cables.

[0004] This approach has significant limitations: First, the data integration is low, making simultaneous monitoring of multiple parameters difficult. A single probe typically measures only one or two parameters (such as water level and temperature), making it difficult to simultaneously acquire key water quality indicators such as conductivity, pH value, and the concentration of multiple ions. This results in redundant equipment, complex deployment, and high costs. Second, signal transmission quality and reliability are poor. Long-distance cables are susceptible to electromagnetic interference and suffer from severe signal attenuation, affecting data accuracy.

[0005] In addition, the sensors in the above-mentioned methods are immersed in complex aquifer environments for a long time, and their surfaces are prone to scaling, biological adhesion, or corrosion, which leads to distortion of measurement data. Frequent removal and cleaning of the probes for maintenance is costly, resulting in low efficiency in obtaining hydrogeological parameters. Utility Model Content

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings.

[0029] The intelligent probe device provided by this utility model is used for underground borehole hydrogeological monitoring, such as... Figure 1 As shown, the intelligent probe device provided by this utility model includes: a probe body 1, a multi-parameter sensor array, a self-cleaning module, a control module, and a power module 3. The probe body 1 is a cylindrical shell, including a detection end and a communication end, which are opposite ends. The multi-parameter sensor array is fixed to the detection end of the probe body 1. The multi-parameter sensor array includes multiple sensors, which can collect hydrogeological data of different dimensions within the borehole, such as water level, temperature, conductivity, pH value, and multi-parameter water quality information.

[0030] The self-cleaning module is fixed to the outer surface of the multi-parameter sensor array and is used to clean multiple sensors. The control module is fixed inside the probe body 1 and is communicatively connected to both the multi-parameter sensor array and the self-cleaning module. The control module controls the multi-parameter sensor array to acquire data and obtains real-time data from the sensors. Based on the trend of real-time data changes, it determines the sensor contamination status and then controls the start and stop of the self-cleaning module to ensure the sensor surface is clean and avoid interference from biological adhesion or deposits on measurement accuracy. The power module 3 is fixed inside the probe body 1 and is electrically connected to the multi-parameter sensor array, the self-cleaning module, and the control module. It provides stable power support for the entire device to ensure the normal operation of each module.

[0031] In this embodiment of the invention, the multi-parameter sensor array includes a water level sensor 6, a temperature sensor 7, a conductivity sensor 8, a pH sensor 10, and a multi-parameter water quality sensor 9.

[0032] For example, water level sensor 6 is used to measure the water level in the borehole, acquiring water depth data in real time through pressure sensing. It employs a silicon piezoresistive pressure sensor with a range of 0-20 MPa and a measurement accuracy of ±0.1 MPa. Temperature sensor 7 is used to monitor the water temperature inside the borehole, with a range of 0-120℃ and a measurement accuracy of ±0.1℃. Conductivity sensor 8 is used to detect the ion concentration in the water, featuring automatic temperature compensation to ensure the accuracy of measurement results under different temperature conditions. pH sensor 10 uses a combination of glass electrode and reference electrode, with an anti-fouling coating on the surface to effectively resist contamination and improve long-term monitoring stability. Multi-parameter water quality sensor 9 integrates multiple detection units, enabling simultaneous acquisition of multiple water quality indicators to comprehensively reflect the water environment status inside the borehole. For example, multi-parameter water quality sensor 9 can achieve K... + Na + Ca 2+ Mg 2+ Fe 3+ Fe 2+ NH 4+ Cl - SO4 2- HCO3 - NO3 - NO2 - The detection of parameters such as F+, Mn, mineralization and total hardness.

[0033] In this embodiment of the present invention, the communication end of the probe body 1 is provided with a communication interface 2, and the control module includes a communication component 5 and a data processing component 4, both of which are communicatively connected to the communication interface 2.

[0034] Communication component 5 is used to transmit the collected hydrogeological data to the surface monitoring system in real time via communication interface 2. Data processing component 4 is responsible for processing the received hydrogeological data and determining whether there are any data anomalies.

[0035] In this embodiment of the invention, the communication interface 2 includes an optical fiber interface and / or a wireless communication antenna, wherein the wireless communication antenna supports at least one of LoRa, NB-IoT, or 4G / 5G communication protocols. The optical fiber interface enables optical fiber communication, achieving high-speed, low-latency data transmission and reducing the impact of electromagnetic interference on signal transmission. The wireless communication antenna enables long-distance, low-power data transmission, which is then uploaded to the cloud system via the borehole gateway.

[0036] The wireless communication module is compatible with LoRa, NB-IoT and 4G / 5G protocols, and can automatically switch to the optimal transmission mode according to the on-site network environment to ensure the stability and low latency of data transmission in deep holes (more than 500 meters) or complex geological conditions.

[0037] In this embodiment of the invention, the probe body 1 has a diameter ranging from 50mm to 80mm and a length ranging from 300mm to 500mm, making it suitable for conventional drilling environments and allowing for easy deployment to the target monitoring layer. The probe body 1 is made of corrosion-resistant and high-pressure-resistant stainless steel or titanium alloy, possessing excellent corrosion resistance and mechanical strength, enabling long-term stable operation in extreme downhole environments such as high salinity, high temperature, and high pressure. The probe body utilizes O-rings and epoxy resin potting to achieve a double seal between the sensor and circuit components, effectively preventing well fluid penetration. Even under high temperature, high humidity, and strong vibration conditions, the internal components maintain stable operation.

[0038] In this embodiment of the utility model, the power module 3 is a rechargeable lithium battery, and the power module 3 is charged through an external power interface or a solar charging device.

[0039] like Figure 2 As shown in the embodiment of this utility model, the self-cleaning module includes an ultrasonic cleaning module. The ultrasonic cleaning module includes a drive motor 15, an ultrasonic vibrator 11, and a transducer 12. The ultrasonic vibrator 11 is disposed on the outer surface of the sensor; the drive motor 15 is fixed inside the probe body 1 and is communicatively connected to the control module; the transducer 12 is electrically connected to the ultrasonic vibrator 11 and the drive motor 15 respectively.

[0040] In this way, when the control module starts the self-cleaning module to clean the sensor, it sends a start command to the drive motor 15. The drive motor 15 converts electrical energy into high-frequency mechanical vibration through the transducer 12. The ultrasonic vibrator 11 generates directional ultrasonic energy and acts on the sensor surface. By utilizing the cavitation effect and micro-jet impact, the adhering substances are peeled off, thus achieving deep cleaning of the sensor.

[0041] In this embodiment of the utility model, the self-cleaning module includes a mechanical scraping module, which includes a drive motor 15, a rotating shaft 13, and a rotating scraper 14. The drive motor 15 is fixed inside the probe body 1 and is connected to the control module. The output shaft of the drive motor 15 is connected to the rotating shaft 13, and the other end of the rotating shaft 13 is connected to the rotating scraper 14. The rotating scraper is in contact with the outer surface of the sensor.

[0042] Thus, when the control module activates the mechanical scraping module, the drive motor 15 receives the command and begins to operate. Through the rotating shaft 13, it drives the rotating scraper 14 in a circular motion. The rotating scraper 14 closely adheres to the sensor surface, effectively removing scale, biofilm, and other contaminants through physical scraping. This mechanical scraping method complements the ultrasonic cleaning module, addressing different types and levels of contamination to ensure the sensor remains clean, thereby guaranteeing the accuracy and reliability of measurement data. Furthermore, the mechanical scraping module has a compact design, occupies little space, and does not significantly affect the overall size and performance of the probe body.

[0043] Furthermore, the control module can automatically trigger a self-cleaning program based on preset time intervals or the degree of sensor signal attenuation, enabling intelligent operation and maintenance without human intervention. The control module can also monitor anomalies in hydrogeological data, generating alarm messages when the water level rises by more than 2 meters within 24 hours. These alarm messages are then transmitted in real-time to the monitoring center via a wireless communication module, ensuring that management personnel are promptly aware of potential hazards.

[0044] As can be seen from the above technical solution, this utility model provides an intelligent probe device with a compact overall design and high functional integration, capable of adapting to complex underground environments. Through the multi-parameter sensor array on the probe body 1, key hydrogeological parameters such as water level, temperature, conductivity, pH value, and various ion concentrations can be simultaneously acquired, achieving synchronous monitoring of multiple parameters and effectively solving the problem of low data integration in traditional monitoring methods.

[0045] In practical applications, after the intelligent probe device is lowered to a preset position inside the borehole via an armored cable, the multi-parameter sensor array begins to operate, collecting various parameter data in real time. This data is transmitted to the control module inside the probe body 1. The data processing component 4 in the control module acquires and processes the data, determining whether the sensor surface needs cleaning based on the collected data.

[0046] When the sensor requires cleaning, the control module triggers the self-cleaning module. If the self-cleaning module uses an ultrasonic cleaning module, the drive motor will start, driving the transducer to work. The transducer converts electrical energy into ultrasonic vibrations, which generate high-frequency vibrations on the outer surface of the sensor, thereby shaking off dirt, biological deposits, and other contaminants adhering to the sensor surface, achieving the purpose of cleaning the sensor. If the self-cleaning module uses a mechanical scraping module, the drive motor drives the rotating shaft to rotate, which in turn drives the rotating scraper to rotate. The rotating scraper comes into contact with the outer surface of the sensor, removing contaminants from the sensor surface through scraping action.

[0047] In terms of data transmission, the communication component 5 in the control module transmits the processed data back to the data acquisition system on the ground via the communication interface. The communication interface 2 can be selected from either a fiber optic interface or a wireless communication antenna according to actual needs. The wireless communication antenna supports at least one of LoRa, NB-IoT, or 4G / 5G communication protocols, ensuring the stability and reliability of data transmission and guaranteeing accurate data return even under conditions of high interference or long-distance transmission.

[0048] Power module 3 provides stable power support for the entire device, using a rechargeable lithium battery that can be charged via an external power interface or solar charging device, ensuring the device's power needs for long-term operation in the field. The probe body 1 is made of corrosion-resistant and high-pressure-resistant stainless steel or titanium alloy, and is encapsulated with O-rings and epoxy resin, further enhancing the device's adaptability and durability in complex underground environments.

[0049] Through the above design, the intelligent probe device provided by this utility model has shown significant advantages in underground borehole hydrogeological monitoring, and has provided strong technical support for research and development in related fields.

[0050] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
