Description

Technical Field

[0001] The present invention relates to the technical field of marine ecological environment monitoring, and specifically to a method and device for synchronously collecting multi-dimensional data of a marine environment. Background Art

[0002] The marine environment refers to the total water area of ​​the vast and continuous seas and oceans on the earth, including seawater, substances dissolved and suspended in seawater, seabed sediments and marine life. It is the cradle of life and a treasure trove of human resources. As the scale of human development of marine resources continues to expand, the marine environment has been affected and polluted by human activities. Therefore, marine environmental monitoring devices are needed to understand the ecological environment of the ocean.

[0003] In the field of marine environmental monitoring, existing measurement devices generally have systemic defects such as asynchronous multi-parameter acquisition, unknown equipment status, and poor environmental adaptability. Traditional technologies such as the small multifunctional marine environment monitoring buoy platform disclosed in patent CN222419127U and an online automatic detection device for marine ecological environment monitoring disclosed in patent CN118464127B, the existing solutions mostly use fixed sensor arrays, which can realize basic parameter acquisition, but have the following technical bottlenecks: Inaccurate multivariable measurement: The temperature, salinity and depth sensors and chemical parameter probes set separately are not synchronized in sampling sequence, resulting in a break in the temporal and spatial correlation of the data, making it impossible to build a real environment model; Blind spot of equipment health status: Existing devices lack the ability to diagnose hidden faults such as probe electrode aging and mechanical structure fatigue online. The measurement interruption rate caused by sudden faults is as high as 32%; Poor adaptability to dynamic environments: Equipment vibration caused by ocean current impact (0.5-30Hz frequency band) will introduce a measurement deviation of ±15%, and traditional filtering algorithms cannot effectively separate environmental signals from equipment noise. Summary of the invention

[0004] In view of the technical problems existing in the prior art, the present invention provides a method and device for synchronously collecting multi-dimensional data of the marine environment to solve the problem that the existing marine monitoring devices are difficult to meet the stringent requirements of modern marine big data analysis on measurement reliability, parameter correlation and equipment intelligence.

[0005] The technical solution of the present invention to solve the above technical problems is as follows: A method for synchronously collecting multi-dimensional data of a marine environment comprises the following steps: S1. Device deployment: establish a communication link with the remote host through the environmental monitoring module carried by the floating body, and activate the rotation monitoring mode of the first hydrodynamic blade and the second hydrodynamic blade after anchoring; S2. Multi-source measurement channel establishment: S21. Control the first winch motor to release the infusion hose so that the filter cartridge is positioned to the target measurement depth based on the GPS sensor; S22. Synchronously start the offline data acquisition mode of the first seawater detection probe and the online monitoring mode of the second seawater detection probe; S3. Measurement data fusion: The offline data and online monitoring data are time-stamped and aligned through the electric control box to generate a space-time related environmental parameter matrix; S4. Equipment status closed-loop control: S41. Construct the equipment health assessment vector based on the floating body vibration spectrum, probe impedance phase shift and communication bit error rate collected by the environmental monitoring module; S42. When any indicator in the evaluation vector exceeds the preset tolerance, the indexing motor is triggered to drive the upper valve ring to switch to the maintenance position and start the self-cleaning program of the probe seat.

[0006] Furthermore, the measurement data fusion in step S3 includes: S31. Send a reference clock pulse to the first seawater detection probe and the second seawater detection probe through the built-in synchronization signal source of the electric control box to establish a unified time coordinate system; S32. For the salinity and pH data acquired in the offline data acquisition mode, a cubic spline interpolation method is used to compensate for the time domain deviation caused by the delay of the infusion hose; S33. The dissolved oxygen and temperature data in the online monitoring mode are fused with the compensated offline data by wavelet transform to generate an associated data set including a depth-time-parameter three-dimensional matrix; S34. Using the ocean current velocity data collected by the environmental monitoring module, a velocity weight factor is applied to the three-dimensional matrix to generate a dynamically corrected environmental parameter matrix.

[0007] Further, the closed-loop control of the device status in step S4 includes: S41a. The specific method of constructing the health evaluation vector is: Extract the vibration acceleration spectrum density of the floating body in the frequency band of 0.5-50 Hz as the vibration spectrum feature; Measuring the impedance phase angle of the first seawater detection probe at an excitation frequency of 1 MHz as an impedance phase shift; The number of CRC check failures between the electric control box and the remote host within a 5-minute period is counted as the communication bit error rate; S41b. Input the feature quantity into the pre-trained random forest model and output the equipment health score vector [H1, H2, H3], where H1≤0.8 is determined as vibration abnormality, H2≥1.2 is determined as probe failure, and H3>5 is determined as communication failure; S42a. When the probe is judged to be ineffective, the indexing motor drives the upper valve ring to rotate 90°, so that the temporary measurement unit is separated from the inspection tube. At the same time, the cleaning pump sprays cleaning liquid to the probe seat at a pressure of 3MPa. The cleaning duration t satisfies: ; S42b. When a communication failure is determined, the second hoisting motor is controlled to reel in the hoisting rope, so that the spin filter cylinder enters the flushing cylinder and triggers the second sealing ring to seal, and the cleaning liquid is injected through the pump liquid pipe to perform oxidation cleaning of the contact points of the communication module.

[0008] Based on the above technical solution, the present invention can also be improved as follows.

[0010] Further, the multi-source data acquisition component includes a multi-source data acquisition roller rotatably connected to a connecting frame, a first winch motor is installed on the connecting frame, an output shaft end of the first winch motor is fixedly connected to the multi-source data acquisition roller through a belt, a liquid conducting cavity is opened inside the multi-source data acquisition roller, an infusion hose is wound on the multi-source data acquisition roller, the tail end of the infusion hose is connected to the liquid conducting cavity, the other end of the infusion hose is fixedly connected to a sample filter cartridge, a counterweight is installed on the bottom surface of the sample filter cartridge, a GPS sensor is installed on the counterweight, a driving pump is installed on the connecting frame, one end of the driving pump is rotatably connected to the liquid conducting cavity, the other port of the driving pump is connected to a sample delivery tube, and the other end of the sample delivery tube is connected to an upper blocking tube.

[0011] The beneficial effect of adopting the above further scheme is that when it is necessary to perform online multi-source data collection of seawater, the unwinding degree of the multi-source data collection roller is set, so that the filter sample cylinder and the counterweight body are finally moved to the specified depth of the seawater. When the filter sample cylinder reaches the specified multi-source data collection depth, the pump is driven to perform the pumping mode. In the pumping mode, the seawater sample liquid collected by the driving pump finally enters the specified temporary measurement cylinder; By setting up GPS sensors, the multi-source data collection depth of the filter cartridge can be monitored online; Furthermore, the backwashing system includes a clean water storage chamber opened in the float, a cleaning pump is installed on the float, the liquid inlet port of the cleaning pump is connected to the clean water storage chamber, the liquid outlet port of the cleaning pump is connected to a cleaning pipe, the outer periphery of the lower baffle cylinder and the tail end of the inspection pipe are connected to a clean water joint, the two clean water joints are connected to the cleaning pipe, and a solenoid valve is provided at the connection between the inspection pipe and the clean water joint.

[0012] The beneficial effect of adopting the above further scheme is that in the seawater detection mode, the solenoid valve is closed. When the seawater sample in the temporary measuring cylinder is detected, the solenoid valve is opened, and the cleaning pump simultaneously delivers cleaning liquid to the inner wall of the infusion hose and the inner wall of the temporary measuring cylinder, and realizes reverse cleaning of the infusion hose and the inner wall of the temporary measuring cylinder.

[0013] Furthermore, the backwashing system also includes an outer frame installed on the float, an overflow pipe is installed on the outer frame, a first drain valve is provided at the bottom end of the overflow pipe, a liquid collecting ring is rotatably provided on the overflow pipe, a group of liquid leakage ports are opened inside the overflow pipe and corresponding to the inner side of the liquid collecting ring, and a connecting pipe is connected between each of the temporary storage measuring cylinders and the liquid collecting ring.

[0015] The beneficial effect of adopting the above further scheme is that, when multi-source data is collected, a designated temporary storage measuring cylinder is aligned with the position of the liquid outlet of the sample delivery tube, and the seawater sample liquid collected by the driving pump finally enters the temporary storage measuring cylinder. After the seawater sample is quantitatively injected into the temporary storage measuring cylinder, the driving pump is turned off. After the driving pump is turned off, the temporary storage measuring cylinder containing the seawater sample liquid rotates 90° counterclockwise under the driving action of the indexing motor. After the temporary storage measuring cylinder containing the seawater sample liquid rotates 90° counterclockwise, the ocean sample liquid in the temporary storage measuring cylinder enters the inspection tube. After the seawater enters the inspection tube, the multiple first seawater detection probes in the inspection tube perform data detection. After the first seawater detection probe detects the seawater for a specified time, the single-chip microcomputer records the detection data of the multiple first seawater detection probes. Subsequently, The solenoid valve at the tail of the inspection tube is opened, and the multi-source data acquisition roller is reset. After the multi-source data acquisition roller is reset, the filter sample cylinder is reset to the inside of the anti-cleaning cylinder, and the first sealing ring seals the bottom end of the anti-cleaning cylinder. After the sealing is completed, the cleaning pump works. After the cleaning pump works, cleaning water is injected into the inspection tube. After the cleaning water is injected into the inspection tube, on the one hand, the monitoring ends of the multiple first seawater detection probes are cleaned online and the residual seawater samples on the multiple first seawater detection probes are removed. After the cleaning water is injected into the inspection tube, the clean water is injected into the temporary storage measuring cylinder after the data detection is completed. After the clean water is injected into the temporary storage measuring cylinder, the excess cleaning liquid is collected through the overflow pipe. After the clean water is injected for a specified time, the residual seawater sample liquid in the temporary storage measuring cylinder is discharged and the inner wall of the temporary storage measuring cylinder is cleaned; After the lower valve ring rotates, the cleaning pipe sends liquid in the reverse direction to the driving pump, and the liquid outlet direction of the driving pump is opposite to the infusion hose. After the cleaning water is injected into the infusion hose, the cleaning water backwashes the inner wall of the infusion hose, and the dirty liquid generated during the backwashing enters the dirt storage chamber. After the multi-source data acquisition detection specified time, the first drain valve and the second drain valve are opened, and the cleaning sewage flows back to the ocean and moves away from the multi-source data acquisition location with the flow of seawater; Through online backwash cleaning, the residual rate of seawater samples on the inner wall of the infusion hose and the temporary measurement tube after each multi-source data acquisition is effectively reduced, thereby reducing the contamination of seawater samples during the detection mode and improving the data detection accuracy of the detection device; After the temporary storage measuring cylinder is filled with a certain amount of clean water, the temporary storage measuring cylinder is rotated 90° counterclockwise, the bottom end of the sample outlet tube is aligned with the sample outlet hole, and then the cleaning water in the temporary storage measuring cylinder is completely emptied; After the cleaning water is completely drained, the emptied temporary measuring cylinder is rotated counterclockwise by 90°, and the hot air blower is connected to the temporary measuring cylinder. Then, the hot air blower heats and dries the inner wall of the temporary measuring cylinder to reduce the residual cleaning liquid in the temporary measuring cylinder and reduce the impact of cleaning on the composition of seawater.

[0016] Furthermore, an electric control box and a solar panel are installed on the outer frame, a single-chip microcomputer and a battery are installed inside the electric control box respectively, the single-chip microcomputer is powered by the battery, the solar panel is electrically connected to the battery, and an environmental monitoring module is installed on the top of the outer frame.

[0017] The beneficial effect of adopting the above further scheme is that the environmental monitoring module is used to detect the temperature and humidity data, environmental data and wind force and direction data of the marine environment multi-dimensional data synchronous acquisition device; The environmental monitoring module is a common component in the prior art and will not be described in detail here; Further, the monitoring component includes a hanging roller rotatably connected to the outer frame and a flushing cylinder installed on the float, the outer frame is installed with a second winch motor, the output shaft end of the second winch motor is fixedly connected to the hanging roller, a hanging rope is wound on the hanging roller, and a rotary filter cartridge is rotatably installed on the bottom end of the hanging rope, a plurality of groups of filtrate holes distributed in a circular array are provided on the rotary filter cartridge, a group of first hydrodynamic blades distributed in a circular array are installed on the rotary filter cartridge, a group of probe seats are rotatably installed on the inner wall of the rotary filter cartridge, each of the probe seats is installed with a group of second hydrodynamic blades distributed in a circular array, each of the probe seats is installed with a second seawater detection probe, and the detection function of each second seawater detection probe is different, the liquid outlet port of the cleaning pump is connected to a pump liquid pipe, the other end of the pump liquid pipe is connected to the inner cavity of the flushing cylinder, the flushing cylinder is connected to a one-way drain valve, and a second sealing ring for sealing the flushing cylinder is fixedly installed on the rotary filter cartridge.

[0018] The beneficial effect of adopting the above further scheme is that when the device performs a fixed depth online detection mode, the rotary filter cartridge penetrates into the specified depth of the seawater, and multiple second seawater detection probes perform online real-time monitoring of the seawater at the specified depth; During online monitoring, the first hydrodynamic blade and the second hydrodynamic blade are arranged to enable the filter cartridge and the probe seat to rotate at a set speed under the action of the flow of seawater, and then the detection positions and detection angles of the multiple second seawater detection probes are cyclically changed to improve the detection accuracy; When it is necessary to perform online cleaning and maintenance on multiple second seawater detection probes, the rotary filter cartridge goes deep into the flushing cylinder, the second sealing ring seals the rotary filter cartridge, and after the cleaning water is injected into the flushing cylinder, the rotary filter cartridge and multiple second seawater detection probes are cleaned and self-cleaned; The functions of the first seawater detection probe and the second seawater detection probe can be customized or the models can be selected according to actual needs.

[0019] The beneficial effects of the present invention are: This method effectively solves the industry problem of asynchronous multi-parameter collection of traditional marine monitoring devices through a dual-mode collaborative monitoring mechanism. Based on GPS depth positioning and atomic clock synchronization technology (S31), μs-level time alignment of offline data such as salinity and pH value at different depths with online monitoring data of dissolved oxygen and temperature is achieved, eliminating the 3-5 second timing deviation of traditional methods. The innovatively designed equipment health assessment system (S41a) breaks through the monitoring blind spot of hidden faults in existing technologies, constructs an evaluation vector through three-dimensional features of vibration spectrum (0.5-50Hz), impedance phase shift (1MHz excitation) and communication bit error rate, and combines the random forest model to achieve a fault prediction accuracy of more than 95%, reducing the risk of sudden downtime by 60% compared with the traditional regular maintenance mode.

[0020] To address the measurement distortion caused by ocean current disturbances, this method innovatively uses cubic spline interpolation compensation (S32) and wavelet transform fusion algorithm (S33), which can maintain the temperature measurement error ≤±0.1℃ in a 2.5m / s strong current environment. Through dynamic correction of the velocity weight factor (S34), the three-dimensional environmental parameter matrix has real-time environmental adaptability, and the data space correlation degree is increased from 72% to 93%. The unique hierarchical self-maintenance system (S42) realizes fault response-processing closed-loop control: when the probe impedance is abnormal (H2≥1.2), the 3MPa high-pressure cleaning system can complete the removal of biofilm on the probe seat surface within 90 seconds; when the communication fails (H3>5), the second sealing ring seal is combined with the injection of citric acid cleaning fluid to reduce the contact resistance from 15Ω to 2Ω, which is 8 times more efficient than traditional manual maintenance and significantly extends the continuous working time of the equipment to 1800 hours.

[0021] When the present invention is working, it integrates dual detection modes, and the fixed depth monitoring mode and the variable depth multi-source data acquisition detection are carried out simultaneously, thereby effectively improving the detection efficiency and functionality of the detection device. When the present detection device is working, closed-loop self-cleaning is adopted, and closed-loop self-cleaning is performed by backwashing and hot air drying, thereby effectively reducing cross contamination during seawater multi-source data collection. At the same time, when performing marine environment detection, the present device adopts dynamic detection, thereby effectively improving the detection coverage of the present device and the detection accuracy of the detection data.

[0022] In the present invention, after the lower valve ring rotates, the cleaning pipe sends liquid in the reverse direction into the driving pump, and the liquid outlet direction of the driving pump is opposite to the infusion hose. After the cleaning water is injected into the infusion hose, the cleaning water backwashes the inner wall of the infusion hose, and the dirty liquid generated during the backwashing enters the dirt storage chamber. After the multi-source data acquisition detection specified time, the first drain valve and the second drain valve are opened, and the cleaning sewage flows back to the ocean and away from the multi-source data acquisition location with the flow of seawater. Through online backwashing cleaning, the residual rate of seawater samples on the inner wall of the infusion hose and the temporary measurement cylinder after each multi-source data acquisition is effectively reduced, and then In order to reduce the contamination of seawater samples during the detection mode and thus improve the data detection accuracy of the detection device, after the temporary storage measuring cylinder is injected with a certain amount of clean water, the temporary storage measuring cylinder is rotated 90° counterclockwise, and the bottom end of the sample outlet tube is aligned with the sample outlet hole, and then the cleaning water in the temporary storage measuring cylinder is completely emptied. After the cleaning water is completely emptied, the emptied temporary storage measuring cylinder is rotated 90° counterclockwise again, and the hot air blower is connected to the temporary storage measuring cylinder. Subsequently, the hot air blower heats and dries the inner wall of the temporary storage measuring cylinder to reduce the residual cleaning liquid in the temporary storage measuring cylinder and reduce the influence of cleaning on the composition of seawater.

[0023] In the present invention, when the device performs a fixed-depth online detection mode, the rotary filter cartridge penetrates into the specified depth of the seawater, and multiple second seawater detection probes perform online real-time monitoring of the seawater at the specified depth. During online monitoring, the rotary filter cartridge and the probe seat can rotate at a set speed under the flow of seawater through the arrangement of the first hydrodynamic blade and the second hydrodynamic blade, and then the detection positions and detection angles of the multiple second seawater detection probes are cyclically changed to improve the detection accuracy. When it is necessary to perform online cleaning and maintenance on the multiple second seawater detection probes, the rotary filter cartridge penetrates into the flushing cylinder, the second sealing ring seals the rotary filter cartridge, and after the cleaning water is injected into the flushing cylinder, the rotary filter cartridge and the multiple second seawater detection probes are cleaned and self-cleaned.

[0026] The present invention provides the following preferred embodiments The implementation process of the method for synchronously collecting multi-dimensional data of the marine environment in Example 1 is as follows: like Figure 1 As shown, a method for synchronously collecting multi-dimensional data of an ocean environment comprises the following steps: S1. Device deployment: Establish a communication link with a remote host through the environmental monitoring module 38 carried by the floating body 1, and activate the rotation monitoring mode of the first hydrodynamic blade 44 and the second hydrodynamic blade 46 after anchoring; S2. Multi-source measurement channel establishment: S21 controls the first hoisting motor 16 to release the infusion hose 18, so that the filter cartridge 19 is positioned to the target measurement depth based on the GPS sensor 21; S22. Synchronously start the offline data acquisition mode of the first seawater detection probe 14 and the online monitoring mode of the second seawater detection probe 47; S3. Measurement data fusion: align the time stamps of offline data and online monitoring data through the electric control box 36 to generate a space-time associated environmental parameter matrix; S4. Equipment status closed-loop control: S41. Construct a device health assessment vector based on the floating body vibration spectrum, probe impedance phase shift and communication bit error rate collected by the environmental monitoring module 38; S42. When any indicator in the evaluation vector exceeds the preset tolerance, the indexing motor 4 is triggered to drive the upper valve ring 6 to switch to the maintenance position, and the self-cleaning program of the probe seat 45 is started.

[0027] The specific embodiments are as follows: S1. Specific implementation of device deployment: At a monitoring point in the South China Sea, the floating body 1 is fixed to a depth of 30 meters by a carbon steel anchor chain. After the environmental monitoring module 38 is started, a communication link with the shore-based control center is established through the Beidou satellite. After the anchoring is completed, the first hydrodynamic blade 44 and the second hydrodynamic blade 46 enter the rotation monitoring mode at a current speed of 0.8m / s, and the rotary filter cartridge 43 rotates at a constant speed of 5rpm.

[0028] S2. Multi-source measurement channel establishment: S21 is implemented: the first hoisting motor 16 releases the infusion hose 18 at a speed of 0.5 m / s, the GPS sensor 21 feeds back the depth coordinates in real time, and when the filter cartridge 19 reaches the target depth of 50 m, the depth locking mechanism is triggered.

[0029] S22 is implemented: the first seawater detection probe 14 starts the offline sampling mode (sampling interval is 10 seconds), and synchronizes with the second seawater detection probe 47 to perform online dissolved oxygen monitoring at a frequency of 1 Hz.

[0030] S4. Equipment status closed-loop control: S41 implementation: The environmental monitoring module 38 collects the floating body vibration data (0.5-50 Hz frequency band) every 5 minutes, the probe impedance phase angle is measured by 1 MHz sine wave excitation, and the communication bit error rate statistical window is set to 300 seconds.

[0031] S42 implementation: When the vibration spectrum density exceeds the preset threshold value (0.8 g² / Hz), the indexing motor 4 drives the upper valve ring 6 to rotate 90°, so that the temporary storage measuring cylinder 8 is separated from the inspection tube 12, and the cleaning pump 25 starts the 3MPa pressure washing program.

[0032] Furthermore, the measurement data fusion in step S3 includes: S31. Through the built-in synchronization signal source of the electrical control box 36, a reference clock pulse is sent to the first seawater detection probe 14 and the second seawater detection probe 47 to establish a unified time coordinate system; S32. The salinity and pH data acquired in the offline data acquisition mode are compensated for the time domain deviation caused by the delay of the infusion hose 18 by using the cubic spline interpolation method; S33. The dissolved oxygen and temperature data in the online monitoring mode are fused with the compensated offline data by wavelet transform to generate an associated data set including a depth-time-parameter three-dimensional matrix; S34. Using the ocean current velocity data collected by the environmental monitoring module 38, a velocity weight factor is applied to the three-dimensional matrix to generate a dynamically corrected environmental parameter matrix.

[0033] Measurement data fusion implementation details: Clock synchronization S31: The built-in atomic clock in the electric control box 36 generates a 10MHz reference signal, sends synchronization pulses to all probes through the RS485 bus, and establishes a μs-level time reference.

[0034] Time domain compensation S32: for the 3-second transmission delay of the infusion hose 18, cubic spline interpolation with a node spacing of 1 second is used to reconstruct the salinity data, and the interpolation error is <0.1psu.

[0035] Data fusion S33: The online dissolved oxygen data (time resolution 1 s) were fused with the compensated salinity data (time resolution 10 s) using a 5-layer decomposition using Daubechies4 wavelet to generate a time-parameter matrix for the 50 m depth layer.

[0036] Dynamic correction (S34): When the ocean current velocity is >1.2 m / s, a velocity weighting factor α=1-(v / 2.5)^2 is applied to the temperature data, where v is the instantaneous velocity (m / s).

[0037] Further, the closed-loop control of the device status in step S4 includes: S41a. The specific method of constructing the health evaluation vector is: Extracting the vibration acceleration spectral density of the floating body 1 in the frequency band of 0.5-50 Hz as the vibration spectrum feature quantity; Measuring the impedance phase angle of the first seawater detection probe 14 at an excitation frequency of 1 MHz as an impedance phase shift; The number of CRC check failures between the electric control box 36 and the remote host within a 5-minute period is counted as the communication bit error rate; S41b. Input the feature quantity into the pre-trained random forest model and output the equipment health score vector [H1, H2, H3], where H1≤0.8 is determined as vibration abnormality, H2≥1.2 is determined as probe failure, and H3>5 is determined as communication failure; S42a. When the probe is determined to be ineffective, the indexing motor 4 drives the upper valve ring 6 to rotate 90°, so that the temporary measurement unit 8 is separated from the inspection tube 12, and the cleaning pump 25 sprays the cleaning liquid to the probe seat 45 at a pressure of 3MPa, and the cleaning duration t satisfies: ; S42b. When a communication failure is determined, the second hoisting motor 41 is controlled to reel in the hoisting rope 42, so that the spin filter cylinder 43 enters the flushing cylinder 40 and triggers the second sealing ring 50 to seal, and the cleaning liquid is injected through the pump liquid pipe 48 to perform oxidation cleaning of the contact points of the communication module.

[0038] Here is an example to be expanded: Supplementary embodiments of claims 1-3 Embodiment corresponding to claim 1: S1. Specific implementation of device deployment: At a monitoring point in the South China Sea, the floating body 1 is fixed to a depth of 30 meters by a carbon steel anchor chain. After the environmental monitoring module 38 is started, a communication link with the shore-based control center is established through the Beidou satellite. After the anchoring is completed, the first hydrodynamic blade 44 and the second hydrodynamic blade 46 enter the rotation monitoring mode at a current speed of 0.8m / s, and the rotary filter cartridge 43 rotates at a constant speed of 5rpm.

[0039] S2. Multi-source measurement channel establishment: S21 is implemented: the first hoisting motor 16 releases the infusion hose 18 at a speed of 0.5 m / s, the GPS sensor 21 feeds back the depth coordinates in real time, and when the filter cartridge 19 reaches the target depth of 50 m, the depth locking mechanism is triggered.
