Description

Technical Field

[0001] This invention relates to the field of drainage well measurement technology, and in particular to a smart pole for measuring the water depth, mud depth, well depth, and location of a drainage well. Background Technology

[0002] Due to the practical needs of engineering surveying and geological exploration, it is necessary to observe the depth of existing or planned wells in the area to be surveyed, and simultaneously calculate and accurately measure the burial depth of groundwater level, so as to provide data support for subsequent regional hydrogeological assessment, engineering safety analysis and optimization of construction plan.

[0003] Traditional drainage well measurements typically rely on manual operation, requiring surveyors to manually strap weights to detect depth. This method is not only time-consuming but also has low overall accuracy. Operators are susceptible to environmental factors, physical limitations, and visual errors, leading to relatively low work efficiency. The precision of manual operation is difficult to guarantee, easily causing deviations in some measurement data and affecting the rational scheduling of subsequent construction. Furthermore, due to significant differences in the depth and internal structure of different drainage wells, traditional measuring devices are often difficult to adjust flexibly according to actual conditions, resulting in poor adaptability, reduced equipment efficiency, increased workload for operators, and impact on the overall measurement progress. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of low measurement accuracy and low equipment compatibility in the prior art, and to propose a smart pole for measuring the water depth, mud depth, well depth and location of drainage wells.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A smart pole for measuring water depth, mud depth, well depth, and location of a drainage well includes a telescopic pole, an RTK positioning module at one end of the telescopic pole, an RTU processing module at the bottom of the telescopic pole, an underwater pole at the bottom of the RTU processing module, a mud-entry pole at the bottom of the underwater pole, and a water depth sensor on the outside of the underwater pole.

[0006] Preferably, the bottom of the telescopic rod is threadedly connected to the end of the RTU processing module, the bottom of the RTU processing module is threadedly connected to the end of the underwater rod, and the bottom of the underwater rod is threadedly connected to the end of the mud-entry rod.

[0007] Preferably, the RTK positioning module includes a controller with a screen and a built-in battery.

[0008] Preferably, the RTU processing module is equipped with a laser ranging sensor and a radar ranging sensor, and the RTU processing module is equipped with a built-in battery. The output signal direction of the laser ranging sensor is the same as the axial direction of the telescopic rod, and the output signal directions of the radar ranging sensor and the laser ranging sensor are opposite.

[0009] Preferably, the water depth sensor consists of a sonar sensor and a hydrostatic sensor, and the output signal direction of the sonar sensor is the same as the axial direction of the telescopic rod.

[0010] Preferably, the RTU processing module is equipped with a pressure sensor, which is connected to a static pressure sensor.

[0011] Preferably, the depth sensor has a movable ring at its end, and a sliding ring on the outer wall of the movable ring, with the sliding ring and the rod in the water being coaxially arranged.

[0012] Preferably, both the telescopic rod and the underwater rod are made of carbon fiber, and the sliding ring is made of stainless steel tubing.

[0013] Preferably, the RTK positioning module is connected to the RTU processing module, and the RTU processing module is connected to the water depth sensor.

[0014] Preferably, the outer wall of the mud-feeding rod is provided with a plug, and the plug is arranged in a ring shape.

[0015] Compared with the prior art, the present invention has the following advantages: 1. This invention, by setting up a telescopic rod and an underwater rod, connects the bottom of the telescopic rod to the end of the RTU processing module via threads, and the end of the underwater rod to the bottom of the RTU processing module via threads. This facilitates installation and disassembly by operators according to the depth and internal structure of different drainage wells, improving the applicability and efficiency of the equipment and reducing the workload of operators.

[0016] 2. This invention uses a water depth sensor, sonar, and hydrostatic sensor. During measurement, the rod automatically slides down to the mud-water separation surface in the water. The water depth sensor allows the sonar sensor inside the deep water sensor to measure the distance of the water depth. The air pressure sensor and hydrostatic sensor work together to detect the distance of the water depth when the water is shallow. Based on the laser, radar, and sonar measurements, the water depth, mud depth, and well depth can be calculated. The drainage well is then accurately located using an RTK positioning module.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Reference Figures 1-5 A smart pole for measuring the water depth, mud depth, well depth, and location of a drainage well includes a telescopic pole 3. The end of the telescopic pole 3 is equipped with an RTK positioning module 1 and a controller with a screen. The bottom of the telescopic pole 3 is equipped with an RTU processing module 5. The bottom of the telescopic pole 3 and the end of the RTU processing module 5 are threadedly connected, which allows the operator to adjust the telescopic pole 3 according to the depth in the well to meet the measurement needs of drainage wells of different depths.

[0021] The RTU processing module 5 has an underwater rod 7 at its bottom, and a mud-injection rod 9 at its bottom. The bottom of the RTU processing module 5 and the end of the underwater rod 7 are threaded together. The underwater rod 7 is divided into multiple sections, each 1 meter long, and the ends of the underwater rod 7 are connected by threads. This allows operators to easily add or remove the underwater rod 7 according to the conditions inside the well. The length of the underwater rod 7 can be customized according to actual measurement needs, making the assembly and disassembly of the entire equipment more convenient and facilitating its carrying and transportation by operators.

[0022] The mud-insertion rod 9 comes in various lengths of 100mm, 200mm, 300mm, and 600mm, which can be selected according to the mud depth. This setting makes it convenient for operators to accurately measure drainage wells with different mud depths, avoiding measurement errors caused by unsuitable mud-insertion rod 9 lengths, improving measurement accuracy, enhancing equipment adaptability, and enabling it to cope with various complex and changing drainage well environments. The well depth is calculated by adding the length of the mud-water separation surface E to the wellhead end B.

[0023] like Figure 4 As shown, point B is the wellhead end, point C is the installation position of RTU processing module 5, point D is the air-water surface separation surface, and point E is the mud-water separation surface. The screen controller 2 is fixedly installed on the inner wall of the RTK positioning module 1. The screen controller 2 has a built-in rechargeable battery and Bluetooth and 4G / 5G wireless communication modules. The operator places a plastic reflector at the end B of the well opening and fixes the entire device at the end B of the well opening. The RTK positioning module 1 measures the latitude and longitude coordinates and the elevation of the well opening, thus locating the well. The screen controller 2 is equipped with a control module for receiving data and a Bluetooth connection module, which facilitates the subsequent transmission of data from inside the well and Bluetooth connection with external devices to achieve real-time data sharing and remote monitoring. At the same time, the built-in battery provides stable power support for the RTK positioning module 1 and the screen controller 2, ensuring long-term operation in the field or in environments without external power.

[0024] The RTU processing module 5 is equipped with a laser ranging sensor 4 and a radar ranging sensor 6. The RTU processing module 5 has a built-in battery. The laser ranging sensor 4 outputs a signal upwards. The laser ranging sensor 4 outputs a signal upwards and is reflected by a plastic reflector. The distance from the laser ranging sensor 4 to point B at the wellhead is measured.

[0025] The radar ranging sensor 6 outputs a signal downwards, which can measure the distance from the radar ranging sensor 6 to the water surface. Through the coordinated work of these two ranging sensors, the distance from the laser ranging sensor 4 to the wellhead B and the distance from the radar ranging sensor 6 to the water surface are obtained, providing an accurate basis for subsequent calculations of water depth, mud depth and well depth.

[0026] like Figure 2As shown in partial schematic diagram A, a water depth sensor is provided on the outside of the rod 7 in the water. The water depth sensor consists of a sonar sensor 12 and a hydrostatic sensor 11. The sonar sensor 12 outputs a signal in the upward direction and emits the signal in the upward direction. Since the sonar signal must be transmitted in the water, the distance between the sonar sensor 12 and the air-water separation surface D can be measured, so that the sonar sensor 12 provides data support for water depth measurement.

[0027] The RTU processing module 5 is equipped with a barometric pressure sensor, which is connected to the static pressure sensor 11 via Bluetooth, data communication, or other means. Since the sonar sensor 12 may have difficulty detecting the distance between the mud-water separation surface E and the air-water separation surface D in some drainage wells with extremely shallow water, the barometric pressure sensor contains a sensing diaphragm. This diaphragm detects the water pressure at point D, while the static pressure sensor 11 detects the atmospheric pressure at the current location. By calculating the water pressure and atmospheric pressure values, the static pressure between the mud-water separation surface E and the air-water separation surface D is obtained. The water depth distance is then calculated using a net water pressure conversion formula. This setup ensures accurate water depth data acquisition under varying water depth conditions, improving the reliability and accuracy of the measurement.

[0028] like Figure 3 As shown, the water depth control module 13 is fixedly installed at the end of the water depth sensor, and the sliding ring 10 is fixedly installed on the outer wall of the water depth control module 13. The sliding ring 10 and the underwater rod 7 are coaxially slidably installed. Through the cooperation between the sliding ring 10 and the water depth control module 13, the sliding ring 10 slides on the outer wall of the underwater rod 7. The sliding ring 10 drives the water depth control module 13 to move by its own gravity, so that the water depth control module 13 moves to the mud-water separation surface E. This simplifies the overall structure of the equipment, reduces energy consumption and equipment cost, ensures stability and accuracy during movement, reduces measurement errors caused by shaking or offset, improves the reliability of measurement results, adapts to drainage well measurements at different depths and different mud-water separation surface positions, and enhances the versatility and adaptability of the equipment.

[0029] It should be noted that the water depth sensor is made of stainless steel and has an IP68 waterproof rating, which reduces the risk of damage to the water depth sensor due to prolonged immersion in the drainage well, extends the service life of the equipment, and reduces the maintenance cost.

[0030] Both the telescopic rod 3 and the underwater rod 7 are made of carbon fiber, while the sliding ring 10 is made of stainless steel. This design reduces the overall weight of the equipment. Carbon fiber is characterized by its high strength and lightweight properties, allowing the telescopic rod 3 and the underwater rod 7 to maintain structural strength while reducing the weight of the equipment, making it easier for operators to carry and operate. The stainless steel tube has good wear resistance and corrosion resistance, enabling it to work stably for a long time in the harsh environment of the drainage well. This reduces the frequency of equipment maintenance and replacement, lowers operating costs, improves the overall performance of the equipment, and extends its service life.

[0031] The RTK positioning module 1 uses latitude and longitude coordinates to accurately locate drainage wells down to the centimeter level. Each drainage well is assigned a code based on its location. When the same drainage well is measured multiple times, the positioning code can be used to quickly locate the well being measured.

[0032] The depth sensor is equipped with a depth control module 13. The outer wall of the depth control module 13 is equipped with a sliding ring 10. The sliding ring 10 and the rod 7 in the water are coaxially arranged and slide up and down. The depth control module 13 is equipped with a built-in rechargeable battery and a Rola wireless communication module. This connection method enables rapid data transmission and sharing. The positioning data acquired by the RTK positioning module 1 can be transmitted to the RTU processing module 5 in real time. The RTU processing module 5 transmits the processed data and the water depth data collected by the water depth sensor to the controller with screen 2, which allows operators to keep track of various measurement information of the drainage well in real time, conduct remote monitoring and data analysis, improve work efficiency and decision-making accuracy. The wireless connection method reduces the problems of wire tangling and damage that may exist in traditional wired connections, and enhances the adaptability and stability of the equipment when measuring in the well.

[0033] The plug 8 is fixedly installed on the outer wall of the mud-injection rod 9. The plug 8 is ring-shaped and made of high-strength rubber material, which has good sealing and wear resistance. The plug 8 will not block the water depth control module 13, so that the water depth sensor can slide to the bottom of the mud-injection rod 9 to measure the water depth when there is no mud. The plug 8 will block the sliding ring 10 so that the water depth sensor will not slide out of the rod 7 in the water. With this setting, when the mud-injection rod 9 is inserted into the mud layer at the bottom of the drainage well, the plug 8 can effectively prevent mud from entering the mud-injection rod 9. The ring-shaped setting increases the contact area between the plug 8 and the mud layer, improves the stability of the mud-injection rod 9 in the mud layer, and ensures that the mud-injection rod 9 will not shift due to the loosening of the mud layer during the measurement process, thereby ensuring the accuracy of the mud depth measurement. It is also convenient for the mud-injection rod 9 to be pulled out of the mud layer after the measurement is completed, reducing the labor intensity of the operator and improving the overall measurement efficiency.

[0034] The following sets of data were obtained through experiments; Drainage well number 1 2 3 Location 121.499305 121.499310 121.499400 Laser measurement value 2450.00mm 2400.00mm 1800.00mm Factory configuration values 1220.10mm 1220.10mm 1220.10mm Radar measurements 580.00mm 200.00mm 600.00mm Sonar measurements 305.00mm 280.00mm 50.00mm Static pressure measurement value 342.40mm 380.50mm 320.00mm water depth 346.70mm 700.30mm 320mm Muddy 107.80mm 119.20mm 500.50mm well deep 3670.10mm 3620.10mm 3720.10mm Note: The laser measurement value is the distance from the laser rangefinder 4 to the wellhead end B. The factory configuration value is the sum of the lengths of the rod 7 and the mud rod 9 inserted into the well water. The radar measurement value is the distance from the radar rangefinder 6 to the water surface. The sonar measurement value is the distance from the sonar sensor to the air-water separation surface D. The hydrostatic measurement value is the distance measured by the hydrostatic sensor in the case of sonar failure in extremely shallow water depths. The water depth refers to the vertical distance from the air-water separation surface D to the mud-water separation surface E. This data is obtained by combining the sonar measurement value or the hydrostatic measurement value with the corresponding algorithm to ensure the accuracy of the measurement under different water depth conditions. The mud depth refers to the vertical distance from the mud-water separation surface E to the bottom of the drainage well. It is accurately calculated by combining the actual insertion length of the mud rod 9 with relevant measurement data. The well depth refers to the total vertical distance from the wellhead end B to the bottom of the drainage well. It is calculated by combining the laser measurement value, the radar measurement value, and the lengths of the rod 7 and the mud rod in the water.

[0035] The functional principle of this invention can be explained through the following operational methods: Operators can easily assemble and adjust the equipment by threading the bottom of the telescopic rod 3 to the end of the RTU processing module 5, threading the end of the underwater rod 7 to the bottom of the RTU processing module 5, and threading the bottom of the underwater rod 7 to the end of the mud entry rod 9. If the length of the underwater rod 7 needs to be increased, multiple underwater rods 7 can be threaded together. Operators can also change the diameter of the mud entry rod 9 according to the mud depth, ensuring the adaptability of the equipment and improving the efficiency of the operator during installation. The operator places a plastic reflector at point B to fix the entire equipment at the wellhead end B. By activating the RTK positioning module 1, the end of the mud-feeding rod 9 extends into the bottom of the mud inside the well. The RTK positioning module 1 measures the latitude and longitude coordinates of the drainage well and the wellhead elevation. The operator extends and retracts the telescopic rod 3 to adjust the extension and retraction according to the well depth. By activating the laser rangefinder 4, the laser rangefinder 4 outputs a signal upward, which is then sent to the bottom of the plastic reflector to measure the distance from the laser rangefinder 4 to the wellhead end B. The radar rangefinder 6 outputs a signal downward, which is then sent to the end of the mud-water separation surface E to measure the distance from the radar rangefinder 6 to the air-water separation surface D. The water depth sensor is installed at the end of the water depth control module 13. The sliding ring 10 slides on the outer wall of the rod 7 in the water, and slides to the mud-water separation surface E by its own weight. The water depth sensor is completely immersed in the water. The sonar sensor 12 outputs a signal upward. Since the sonar output signal can only be transmitted in water, the signal output of the sonar sensor 12 is sent to the air-water separation surface D. The distance from the sonar sensor 12 to the air-water separation surface D is measured, thereby measuring the water depth in the well. Furthermore, since the water depth in some wells is extremely shallow, making it difficult for the sonar sensor 12 to make measurements, when the sensing diaphragm of the static pressure sensor 11 is immersed in water, the static pressure sensor 11 senses the water depth pressure. Combined with the atmospheric pressure value obtained by the air pressure sensor set in the RTU processing module 5, the net water pressure is calculated by the screen controller 2, and the water depth distance from the mud-water separation surface at point E to the air-water separation surface at point D is obtained. By uploading various data to the screen controller 2, operators can easily observe and record various distances. At the same time, by packaging and uploading various data of the drainage well, it is convenient for operators to conduct secondary measurements of the drainage well and record the changes in its various data.
