Abstract
Description
Technical Field
[0001] This invention relates to a water level monitoring device, and more particularly to a hydrogeological water level monitoring device and method. Background Technology
[0002] Water level monitoring devices are used in a variety of scenarios, such as the planning, design, construction, and management of water conservancy projects, the construction of bridges, ports, and waterways, and water level monitoring in emergency situations such as flood control and drought relief. In addition, they can be used for the analysis and research of river sediment and hydrological conditions, providing important data support for water resource management and hydrological condition assessment.
[0003] In hydrogeological engineering, water level monitoring devices are used to measure and monitor changes in groundwater levels or water levels in hydrological bodies. They provide real-time data on groundwater or water levels, helping people understand hydrogeological characteristics, water resource management, and hydrological condition assessment. Water level monitoring devices can provide accurate water level data, helping hydrogeologists understand information such as groundwater content, groundwater level changes, and groundwater flow, providing an important data foundation for hydrological engineering and water resource management.
[0004] Hydrological engineering geological water level monitoring devices often employ suspended water level monitoring equipment. However, existing suspended water level monitoring devices are easily affected by the aquatic environment during actual use, leading to inaccurate detection results. For example, under the influence of water flow velocity, the float and counterweight mechanism are not in the same vertical position, causing the traction rope to tilt. In this case, the displacement of the traction rope is not the actual water level height, and the measured result is often too high. In addition, since there are often aquatic plants or other easily entangled debris on the bottom, the counterweight mechanism is easily entangled by aquatic plants or debris after sinking to the bottom. Furthermore, after the counterweight device sinks to the bottom, the entangled aquatic plants or debris will be stirred into the fixing mechanism (such as an auger), causing it to be unable to screw into the bottom or to be pulled and tilted by aquatic plants and other easily entangled debris, thus affecting the fixation of the fixing mechanism. When monitoring waters with a lot of silt, the fixing mechanism is easily affected by silt and sediment, making it difficult to fix. Summary of the Invention
[0005] The present invention aims to provide a water level monitoring device and method for hydrological engineering geology, in order to solve the problem of how to fix the water level monitoring device and avoid its use from being affected by the aquatic environment.
[0006] To achieve the above objectives, the specific plan is as follows:
[0007] A hydrogeological water level monitoring device, comprising:
[0008] A floating device, comprising a floating board and inflatable airbags arranged around the floating board; the floating board is provided with a line release port;
[0009] The monitoring device includes a first placement box, a second placement box, a detection system, a roller, a traction rope, and a first drive motor. The first placement box is positioned directly above the cable release port, the second placement box is positioned against the first placement box, and the first drive motor is located inside the second placement box. The roller passes through the first placement box, with one end penetrating the first placement box and connected to the output shaft of the first drive motor, and the other end rotatably mounted on the side wall of the first placement box. Displacement monitoring elements are provided on the inner wall of the first placement box. The detection system is mounted on a floating plate and connected to the displacement monitoring elements via wiring. The detection system includes an alarm light and a signal transmitter.
[0010] A fixing device includes a connecting hole, a telescopic mechanism, a second drive mechanism, and an annular groove. The connecting hole is located at the top of the fixing device. A first mounting groove is located at the bottom of the fixing device, with a first bearing and a second bearing symmetrically arranged on the inner wall of the first mounting groove. The mounting end of the annular groove is located on the first bearing. A second mounting groove and a third mounting groove are located in the middle of the fixing device, with the second mounting groove positioned centrally and the third mounting groove surrounding the second mounting groove. A telescopic mechanism is located within the second mounting groove, with a fixing plate at its telescopic end. The fixing plate has several through holes. A second drive mechanism is located within the third mounting groove, with its rotating component passing through the first mounting groove and mounted on the second bearing. Matching gears are provided on the contact surfaces of the rotating component and the mounting end, allowing them to mesh together.
[0011] Furthermore, a propeller is installed at the bottom of the floating device.
[0012] Furthermore, a fixing rod is provided in the wire feeding port, and a wire feeding device is provided on the fixing rod, which can move left and right on the fixing rod.
[0013] Furthermore, the fixing device is spherical in shape.
[0014] Furthermore, the fixing device is provided with several drainage holes around its perimeter, which extend through the side wall of the fixing device from its bottom.
[0015] Furthermore, the top of the fixing device is provided with a sensing groove, the bottom of the sensing groove is provided with an electromagnet, and the top of the sensing groove is connected to the connection hole; the end of the traction rope is provided with a disc-shaped block, which is placed inside the sensing groove and coaxially arranged with the electromagnet.
[0016] Furthermore, the bottom of the annular groove is provided with an attack section, which is shaped as larger at the top and smaller at the bottom.
[0017] Furthermore, a stabilizing section is provided above the attack section, which is a continuous threaded ring that is larger at the top and smaller at the bottom.
[0018] Furthermore, the detection system also includes a solar energy module, an AI module, a storage module, a positioning module, and a power storage module, among which:
[0019] The solar module is used to convert solar energy into electrical energy and store the electrical energy in the energy storage module, allowing the device to operate for a long time in the field;
[0020] The storage module is used to store real-time monitoring information and historical monitoring data for this river section.
[0021] The AI module is connected to the storage module and is used to intelligently analyze the historical monitoring data of the river section in the storage module. Based on the data information, it proposes a data anomaly threshold and intelligently controls the roller according to the water level change. It compares the obtained displacement of the traction rope with the proposed data anomaly threshold to determine whether to send an early warning information to the staff.
[0022] The positioning module is used to locate the position information of the floating device or the fixed device and put the corresponding information into the storage module.
[0023] A method for using a hydrogeological water level monitoring device includes the following steps:
[0024] S1, Preparations before device deployment: Check the airtightness of the inflatable airbag and inflate it to 90% expansion rate; test the forward and reverse rotation function of the propeller to ensure that the floating device can be accurately moved to the monitoring point, and check the status of each module of the detection system; import the historical water level data of this river section for the past year and automatically generate abnormal thresholds.
[0025] S2, Initial Positioning and Deployment: The floating device is moved to the target monitoring point by the propeller, the first drive motor is started, the roller rotates clockwise to release the traction rope, and the fixed device sinks to the riverbed under the action of gravity. During this process, the cable laying device moves left and right along the fixed rod to ensure that the traction rope is evenly wound around the roller.
[0026] S3, Initial stabilization and Drilling of the Attack Section: Before the fixing device reaches the riverbed surface, the telescopic mechanism is activated, pushing the fixing plate downwards until it is flush with the bottom of the annular groove; after the fixing device reaches the riverbed surface, the second drive motor is activated, and the rotating parts drive the annular groove to rotate at high speed through gear transmission, so that the attack section drills into the riverbed.
[0027] S4, Depth Adaptation and Final Fixing: The AI module monitors the drilling depth of the annular groove in real time and synchronously controls the telescopic mechanism to ensure that the fixing plate always matches the sinking speed of the annular groove; when the drilling depth of the annular groove reaches the preset value, the second drive motor stops working and the telescopic mechanism keeps the fixing plate against the riverbed.
[0028] S5, Installation Status Feedback and Initial Data Calibration: After the fixing device is fixed, the electromagnet in the induction slot is activated to generate a magnetic field to attract the disc-shaped block at the end of the traction rope; after the disc-shaped block is attracted, it sends an "installation complete" signal to the detection system through the induction signal line inside the traction rope, and the first drive motor immediately stops releasing the rope; the displacement monitoring device records the initial displacement of the traction rope at this time, and the data is synchronously transmitted to the storage module and sent to the worker's terminal through the signal transmitter;
[0029] S6, Real-time Monitoring and Anomaly Handling: When the water level changes, the roller automatically raises and lowers the traction rope according to the rise and fall of the water level. The displacement monitoring device collects displacement data every 10 seconds, converts it into water level height, and stores it in the storage module. The positioning module updates the device position every 30 minutes. If the floating device deviates by more than 2 meters, the AI module controls the propeller to reset. When the water level change exceeds the abnormal threshold preset by the AI module, the alarm light flashes red continuously. The signal transmitter sends a warning message to the staff terminal and transmits the data within 1 hour of the abnormal period to the cloud database for backup.
[0030] S7, Device Recovery and Data Export: Turn off the electromagnet, start the first drive motor to reverse, the rollers wind up the traction rope, and the fixing device rises with the traction rope; during the ascent, the cable winding device moves left and right to ensure that the traction rope is wound evenly and to avoid uneven force on the rollers; after the fixing device is completely recovered below the floating device, turn on the propeller and navigate to the shore through the positioning module.
[0031] In summary, the present invention has the following advantages over the prior art:
[0032] (1) The bottom of the annular groove is equipped with a cone-shaped attack section that is larger at the top and smaller at the bottom, which can quickly break through riverbeds of different textures such as hard soil and soft soil, reducing drilling resistance; the continuous spiral stabilizing section above allows riverbed sediment to be stuck into the spiral gaps, enhancing the integration with the riverbed and preventing the device from loosening. The fixed plate driven by the telescopic mechanism sinks synchronously with the annular groove, always pressing against the riverbed to form a "surface support". Combined with the drilling of the annular groove, it forms double stability, solving the problem that traditional fixed mechanisms are easily entangled by aquatic plants, buried by sediment, or tipped over.
[0033] (2) The spherical fixing device can reduce the impact of water flow and avoid the device from shifting due to the thrust of water flow; the drainage holes that run through all four sides can quickly drain the water inside the device during the sinking process, reduce resistance, ensure that the fixing device sinks vertically to the target position, and further improve the fixing accuracy.
[0034] (3) The cable laying device at the floating plate can move left and right along the fixed rod to ensure that the traction rope is evenly wound on the roller and avoids displacement measurement error caused by rope knots or deviation; the top of the fixed device uses an electromagnet to attract the disc-shaped block at the end of the traction rope, which can calibrate the initial position of the traction rope and ensure that the traction rope is always in a vertical state, thus solving the problem of excessive water level measurement caused by the tilt of the traction rope in traditional devices.
[0035] (4) The AI module can analyze the historical water level data of the river section in the storage module for the past year and automatically generate personalized abnormal thresholds without manual setting. When the water level changes exceed the threshold, the alarm light (flashing red light) and the signal transmitter (pushing early warning information including real-time water level and location) provide a dual warning. At the same time, the data of the abnormal period within 1 hour is automatically backed up to the cloud to prevent data loss. During deployment, the propeller can accurately move the floating device to the target monitoring point, and the fixing device can automatically complete the drilling and fixing through gravity sinking and motor drive. During recovery, it is only necessary to turn off the electromagnet and start the roller to wind up the traction rope. The cable laying device works in sync, without the need for manual underwater operation, reducing the labor cost of deployment and recovery.
[0036] (5) The storage module stores real-time monitoring data and historical data at the same time, and supports data comparison and analysis in the later stage (such as the water level change trend in the same period); the coordinates of the monitoring points recorded by the positioning module can be repeatedly called. If the same anchor point needs to be monitored multiple times, the AI module can automatically navigate to the target location based on the historical coordinates, thereby improving the continuity and comparability of the monitoring data.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.
[0052] See Figures 1 to 9 As shown, this invention provides a hydrogeological water level monitoring device, which mainly consists of three parts: a floating device 1, a monitoring device 2 mounted on the floating device 1, and a fixed device 3 connected to the monitoring device 2.
[0053] The floating device 1 includes a float plate 11 and inflatable airbags 12 arranged around the float plate 11. The float plate 11 and the inflatable airbags 12 provide buoyancy, allowing the floating device 1 to float on the water surface during actual use. Furthermore, the float plate 11 is also provided with a line release port 111.
[0054] The monitoring device 2 mainly consists of a first placement box 21, a second placement box 22, a detection system 23, a roller 24, a traction rope, and a first drive motor 26. The first placement box 21 is positioned directly above the cable release port 111, the second placement box 22 is positioned against the first placement box 21, and the first drive motor 26 is located inside the second placement box 22. The roller 24 passes through the first placement box 21, with one end penetrating the first placement box 21 and connected to the output shaft of the first drive motor 26, and the other end rotatably mounted on the side wall of the first placement box 21. Furthermore, a displacement monitoring element 211 is provided on the inner wall of the first placement box 21 to monitor the displacement of the traction rope mounted on the roller 24. The detection system 23 is mounted on the floating plate 11 and connected to the displacement monitoring element 211 via wiring. The detection system 23 also includes an alarm light 231 and a signal transmitter 232.
[0055] The fixing device 3 includes: a connecting hole 35, a telescopic mechanism 321, a second drive mechanism 331, and an annular groove 34. The cooperation and working principle of each component are as follows:
[0056] A connecting hole 35 is provided on the top of the fixing device 3 for connecting to the extended end of the traction line 25;
[0057] The bottom of the fixing device 3 is provided with a first mounting groove 31, and a first bearing 311 and a second bearing 312 are symmetrically arranged on the inner wall of the first mounting groove 31. The mounting end 341 of the annular groove 34 is arranged on the first bearing 311.
[0058] A second mounting groove 32 and a third mounting groove 33 are provided in the middle of the fixing device 3. The second mounting groove 32 is located in the center of the fixing device 3, and the third mounting groove 33 is arranged around the second mounting groove 32. A telescopic mechanism 321 is provided in the second mounting groove 32, and a fixing plate 322 is provided at the telescopic end of the telescopic mechanism 321. A second drive motor 331 is provided in the third mounting groove 33. The rotating part 3311 of the second drive motor 331 passes through the first mounting groove 31 and is set on the second bearing 312. A matching gear is provided on the contact surface between the rotating part 3311 and the mounting end 341, so that the rotating part 3311 and the mounting end 341 are meshed together.
[0059] In use, the telescopic mechanism 321 first controls the fixed plate 322 to move downwards, making the fixed plate 322 flush with the bottom of the annular groove 34, allowing the bottom of the fixing device 3 to land on the riverbed in a planar manner. After the fixing device 3 is on the riverbed, the second drive motor 331 provides power to the rotating component 3311, causing it to rotate, thereby driving the mounting end 341 and the annular groove 34 to rotate, allowing the annular groove 34 to drill into the riverbed for fixation. During this process, the telescopic mechanism 321 adjusts the telescopic amount according to the drilling speed of the annular groove 34, matching the sinking speed of the fixed plate 322 and the annular groove 34. When the annular groove 34 stops rotating, the telescopic mechanism 321 stops telescopic operation, ultimately forming a stable structure where the fixed plate 322 abuts against the riverbed and the annular groove 34 drills into the riverbed. After the fixing device 3 is fixed, the displacement monitoring component 211 records the displacement of the traction rope and transmits the data to the workers through the signal transmitter 232.
[0060] When the water level rises, the roller 24 can continue to unwind. The height of the water level rise can be determined by measuring the unwinding amount. When the water level exceeds the warning line, the detection system 23 transmits the abnormal information to the staff through the signal transmitter 232 and activates the alarm light 231, which flashes red continuously to alert the staff that the water level is abnormal.
[0061] The device provided by this invention can be placed at any location in the water body, achieving flexible placement and easy relocation later. It also has no limitation on the monitoring range of water level. Through the cooperation of "annular groove 34 + fixed plate 322", it avoids the problem that traditional equipment is easily affected by aquatic plants, silt and other substances.
[0062] In addition, the fixing plate 322 is provided with several through holes 3221 to reduce the water flow resistance encountered by the fixing plate 322 during the descent process.
[0063] As a preferred embodiment, the bottom of the floating device 1 is also provided with a propeller 13, which provides power to the floating device 1 to control the position of the floating device 1 on the water surface.
[0064] As a preferred embodiment, the cable release port 111 is also provided with a fixing rod 1111, and the fixing rod 1111 is provided with a cable laying device 1112. The cable laying device 1112 can move left and right on the fixing rod 1111. During the process of retracting the traction rope, the left and right movement of the cable laying device 1112 can make the traction rope evenly wrap around the roller 24.
[0065] As a preferred option, in order to reduce the impact of water flow and to ensure that the fixing device 3 can be stably fixed on the riverbed for a long time, the fixing device 3 is spherical in shape.
[0066] As a preferred option, in order to make the fixing device 3 sink more smoothly and reduce the displacement deviation caused by resistance during the sinking process, the fixing device 3 is provided with several drainage holes 36 around its perimeter. The drainage holes 36 extend from the side wall of the fixing device 3 along the bottom of the fixing device 3, so that the water at the bottom of the fixing device 3 can flow through the drainage holes 36 during the sinking process, thereby reducing the water flow resistance experienced by the fixing device 3.
[0067] As a preferred embodiment, in order to enable the monitoring device 2 to accurately monitor the information that the fixing device 3 has been installed, the top of the fixing device 3 is also provided with a sensing groove 37, the bottom of the sensing groove 37 is provided with an electromagnet 4, and the top of the sensing groove 37 is connected to the connecting hole 35; at this time, the end of the traction rope is provided with a disc-shaped block 5, which is placed inside the sensing groove 37 and coaxially arranged with the electromagnet 4.
[0068] In use, after the fixing device 3 completes the above operations and is finally fixed on the riverbed, the electromagnet 4 is activated to attract the disc block 5. After the disc block 5 is attracted, the information is transmitted to the detection system 23 through the induction signal line set inside the traction rope. At this time, the roller 24 stops releasing the rope, the displacement monitoring device 211 records the displacement of the traction rope at this moment, and the detection system 23 wirelessly transmits the measurement value to the remote controller, so that the staff can obtain the information that the water level monitoring device 2 has been installed.
[0069] As a preferred option, in order to allow the annular groove 34 to smoothly penetrate into the riverbed, the bottom of the annular groove 34 is provided with an attack section 342. The attack section 342 is designed with a shape that is larger at the top and smaller at the bottom. This shape can significantly increase the pressure of the annular groove 34 during use, making the process of penetrating into the riverbed smoother.
[0070] As a preferred embodiment, to increase the stability of the annular groove 34 within the riverbed and to make its operation smoother, a stabilizing section 343 is provided above the attack section 342. The stabilizing section 343 is a continuous threaded ring that is larger at the top and smaller at the bottom. In actual use, after the attack section 342 drills into the riverbed, the stabilizing section 343 is also drawn into the riverbed. During this process, the water inside the annular groove 34 can flow through the gaps between the stabilizing sections 343, thereby reducing the pressure generated by the water flow inside the annular groove 34 as it continues to move downwards. On the other hand, during this process, the mud, sand, and other debris inside the riverbed will gradually get stuck in the gaps of the stabilizing section 343, thereby increasing the integration of the annular groove 34 with the riverbed and allowing the fixing device 3 to be more firmly installed on the riverbed.
[0071] As a preferred embodiment, the detection system 23 further includes a solar module 233, an AI module 234, a storage module 235, a positioning module 236, and a power storage module 237, wherein:
[0072] The solar module 233 is used to convert solar energy into electrical energy and store the electrical energy in the energy storage module 237, so that the device can operate for a long time in the field;
[0073] The storage module 235 is used to store real-time monitoring information and historical monitoring data for this river section.
[0074] AI module 234 is connected to storage module 235. It can intelligently analyze historical monitoring data of the river section in storage module 235 and formulate data anomaly thresholds based on the data information. In addition, AI module 234 can intelligently control roller 24 according to the water level change of the water area, thereby controlling the displacement of the traction rope. By comparing the real-time traction rope displacement with the formulated data anomaly thresholds, it can intelligently decide whether to control signal transmitter 232 to send early warning information to staff, further reducing the workload of staff.
[0075] The positioning module 236 is used to locate the position information of the floating device 1 or the fixed device 3 and stores the corresponding information in the storage module 235. In actual use, if it is necessary to monitor the same anchor point a second or third time, the position information is input into the AI module 234. At this time, the AI module 234 can control the floating device 1 to move towards the predetermined anchor point. After reaching the predetermined position, it controls the roller 24 and the fixed device 3 to complete the second or third water level monitoring of the same position.
[0076] A method for using a hydrogeological water level monitoring device includes the following steps:
[0077] S1, Preparations before device deployment: Check the airtightness of the inflatable airbag 12 and inflate it to 90% expansion rate (leave buffer space to avoid rupture caused by water flow impact); test the forward and reverse rotation function of the propeller 13 to ensure that the floating device can be accurately moved to the monitoring point; check the status of each module of the detection system 23: the solar module 233 should be facing the direction of sufficient sunlight, and the power storage module 237 should have a power of ≥80%; input the coordinates of the target monitoring point into the positioning module 236; pre-debug the AI module 234: import the historical water level data of the river section for the past year and automatically generate abnormal thresholds (such as daily water level fluctuations of ±5cm are normal, and exceeding ±10cm triggers an early warning).
[0078] S2, Initial Positioning and Deployment: The floating device is moved to the target monitoring point by the propeller 13, the first drive motor 26 is started, the roller 24 rotates clockwise to release the traction rope 25, and the fixed device sinks to the riverbed under the action of gravity; during the deployment process, the drainage holes 36 around the fixed device can quickly drain the internal water, reduce water flow resistance and prevent the device from shifting; the cable laying device 1112 moves left and right along the fixed rod 1111 (the moving speed is synchronized with the release speed of the traction rope, about 0.2m / s) to ensure that the traction rope is evenly wound on the roller and avoids knotting.
[0079] S3, Initial Stabilization and Drilling of the Attack Section: Before the fixing device reaches the riverbed surface, the telescopic mechanism 321 is activated, pushing the fixing plate 322 downwards until it is flush with the bottom of the annular groove 34, forming a "surface contact" for initial stabilization; after the fixing device 3 reaches the riverbed surface, the second drive motor 331 is activated, and the rotating part 3311 drives the annular groove 34 to rotate at high speed (approximately 50 r / min) through gear transmission, and the attack section 342, which has a cone shape with a larger upper part and a smaller lower part at the bottom, quickly drills into the riverbed (drilling depth ≥30 cm for hard soil riverbeds, ≥50 cm for soft soil riverbeds); during this process, the through holes 3221 on the fixing plate can reduce the impact of water flow on the fixing plate, while avoiding soil blockage, ensuring that the fixing plate is in close contact with the riverbed.
[0080] S4, Depth Adaptation and Final Fixation: The AI module 234 monitors the drilling depth of the annular groove in real time (calculated by the displacement of the traction rope) and synchronously controls the telescopic mechanism 321 to ensure that the fixing plate always matches the sinking speed of the annular groove. When the drilling depth of the annular groove reaches the preset value (set according to the hardness of the riverbed, 30cm for hard soil and 50cm for soft soil), the second drive motor 331 stops working, and the telescopic mechanism 321 keeps the fixing plate against the riverbed, forming a double stable structure of "drilling fixation + surface support".
[0081] S5, Installation Status Feedback and Initial Data Calibration: After the fixing device is fixed, the electromagnet 4 in the induction slot 37 is activated to generate a magnetic field to attract the disc block 5 at the end of the traction rope; after the disc block 5 is attracted, it sends an "installation complete" signal to the detection system 23 through the induction signal line inside the traction rope, and the first drive motor 26 immediately stops releasing the rope; the displacement monitoring device 211211 records the initial displacement of the traction rope at this time (i.e., the initial water level height), and the data is synchronously transmitted to the storage module 235 and sent to the worker terminal through the signal transmitter 232.
[0082] S6, Real-time Monitoring and Anomaly Handling: When the water level changes, the roller 24 automatically raises and lowers the traction rope according to the rise and fall of the water level (releasing the rope when the water level rises and retracting it when the water level falls). The displacement monitoring device 211211 collects displacement data every 10 seconds, converts it into water level height, and stores it in the storage module 235. The positioning module 236 updates the device position every 30 minutes. If the floating device deviates by more than 2 meters, the AI module 234 controls the propeller 13 to reset to avoid measurement point deviation. When the water level change exceeds the preset abnormal threshold of the AI module 234, the detection system 23 triggers a dual warning: the alarm light 231 flashes red continuously (flashing frequency 2 times / s) to alert nearby personnel; the signal transmitter 232 sends a warning message to the staff terminal, including real-time water level, abnormal amplitude, device position, etc., and attaches a historical water level comparison chart for the same period to help determine the cause of the abnormality. In addition, the data within 1 hour of this period (abnormal period) is transmitted to the cloud database for backup through the signal transmitter to prevent data loss.
[0083] S7, Device Recovery and Data Export: During recovery, first turn off the electromagnet 4, start the first drive motor 26 to reverse, the roller 24 winds up the traction rope, and the fixing device rises with the traction rope; during the rise, the cable laying device 1112 continues to move left and right to ensure that the traction rope is evenly wound and to avoid uneven force on the roller; after the fixing device is completely recovered to below the floating device, turn on the propeller 13 and navigate to the shore through the positioning module 236.
[0084] Example: Precautions
[0085] I. Waters with dense aquatic plants
[0086] Operational suggestion: Before deploying the anchoring device, move slowly using propeller 13 to avoid obvious clumps of aquatic plants and reduce the initial risk of entanglement.
[0087] II. Waters with high sediment content
[0088] The inner wall of the drain hole 36 is treated with anti-corrosion material (made of 304 stainless steel) to prevent mud and sand from adhering and causing blockage; the surface of the attack section 342 of the annular groove 34 is sprayed with a wear-resistant coating (hardness HRC50 or above) to extend service life.
[0089] Operational recommendation: Increase the drilling depth of the fixing device by 10%-20% to ensure it remains stable after sediment settling.
[0090] III. Waters with rapid currents
[0091] Operational recommendations: When initially deploying the device, choose a period when the water flow is relatively calm. Within 30 minutes after deployment, increase the location monitoring frequency (once every 5 minutes) to ensure that the device does not shift.
[0092] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.
[0093] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.
[0094] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
