[0001] This invention relates to the field of underground hydrological monitoring technology, and in particular to a self-recording wireless transmission hydrological multi-parameter monitoring device. Background Technology

[0002] Groundwater monitoring is a technical means for management departments to implement long-term protection by dynamically tracking groundwater levels, water quality and other data. It aims to grasp the dynamic changes of groundwater and has multiple functions such as measuring water level, pore pressure, permeability and water sampling, and can identify pollution risk sources [7]. The system consists of a monitoring center, communication network and terminal equipment. It relies on the GPRS network to remotely transmit data and has the function of real-time monitoring of water level, temperature, conductivity and other functions.

[0003] Groundwater monitoring has multiple functions, including measuring water level, pore pressure, permeability, and sampling. Furthermore, it can promptly grasp dynamic changes in water quality, accurately identify sources of pollution risk, provide a scientific basis for environmental management decisions, safeguard regional ecological security, and promote sustainable development.

[0023] This invention proposes a self-recording wireless transmission hydrological multi-parameter monitoring device.

[0024] like Figures 1 to 3 The device, shown, is a self-recording wireless transmission hydrological multi-parameter monitoring device, comprising a main body 1, a housing 11, a detection probe 21, a cable 22, a driver 2, a charging mechanism 3, a communicator, and a main controller. The housing 11 is located on one side of the main body 1 and is used to accommodate the wellhead. The driver 2 is disposed inside the main body 1. The detection probe 21 is mounted on one end of the cable 22, and the other end of the cable 22 is connected to the output end of the driver 2. The driver 2 is used to retract and extend the cable 22, and drives the detection probe 21 to move vertically up and down along the well. Several rechargeable repeater modules 4 are mounted on the cable 22, with each rechargeable repeater module 4 arranged along the length of the cable 22. The rechargeable relay modules 4 are arranged at intervals to form a communication channel, which connects the detection probe 21 and the communicator. A receiving space is formed inside the housing 11, and the charging mechanism 3 is located on the side of the housing 11 away from the main body 1. The main controller is electrically connected to the driver 2, the charging mechanism 3 and the communicator. The main controller is used to obtain the monitoring data of the detection probe 21 in sequence through the communicator and the communication channel. The main controller is also used to control the driver 2 according to a preset time point to drive each rechargeable relay module 4 that constitutes the communication channel to enter the first preset position in sequence, so that the charging mechanism 3 charges the rechargeable relay module 4 located in the first preset position.

[0025] Each rechargeable relay module 4 is laid out along cable 22 to form a segmented communication channel, forwarding detection signals step by step. This effectively overcomes the problems of wireless communication signal attenuation and wired direct connection communication interruption in deep well environments, ensuring stable and continuous transmission of hydrological monitoring data. The main controller controls the driver 2 and the charging mechanism 3 according to preset time points to achieve cyclical recharging of all rechargeable relay modules 4. No manual disassembly and charging is required, ensuring that the rechargeable relay modules 4 can work online for a long time, greatly improving continuous monitoring time. Furthermore, if any rechargeable relay module 4 is damaged, it can be easily and promptly replaced, ensuring safe monitoring operations for a long time.

[0026] Specifically, the outer shell 11 and the main body 1 are detachably connected. The outer shell 11 can effectively protect the internal mechanical and electrical structures such as the charging mechanism 3, and prevent external debris from entering the well or accumulating at the wellhead.

[0027] Specifically, the detection probe 21 is used to detect parameters related to hydrogeology, such as water level, water temperature, TDS, dissolved oxygen, and pH value. Among them, the water level includes at least one of the maximum daily water level drop and the shallowest water level at the monitoring point; the water temperature includes at least one of the maximum daily water temperature drop and the minimum water temperature at the monitoring point.

[0028] A camera 12 is installed inside the housing 11 to acquire first image information at a first preset position. The driver 2 includes a fixed pulley 23, a reel 24, a first servo motor 25, and an adjustment mechanism 5. The reel 24 is located on the main body 1, and the fixed pulley 23 is located on the side of the main body 1 facing the housing 11. The fixed pulley 23 is located within the accommodating space and is positioned above the wellhead. One end of the cable 22 is connected to the reel 24, and the other end of the cable 22 is connected to the detection probe 21 via the fixed pulley 23. The cable 22 is wound around the reel 24. The adjustment mechanism 5 is located on the main body 1 facing the charging position. On one side of mechanism 3, adjustment mechanism 5 is used to drive charging relay module 4 to rotate horizontally when any charging relay module 4 enters the first preset position, so as to align the charging port of charging relay module 4 with charging mechanism 3; main controller is electrically connected to camera 12, first servo motor 25 and adjustment mechanism 5 respectively, and main controller is used to control first servo motor 25 and adjustment mechanism 5 according to preset time points to send each charging relay module 4 into the first preset position in sequence; main controller is used to control adjustment mechanism 5 to adjust the horizontal direction of each charging relay module 4 in sequence according to first image information.

[0029] Camera 12 acquires real-time images (i.e., first image information) of the first preset position, providing visual basis for the main controller to control the driver 2, charging mechanism 3, and fixing mechanism 6 respectively. Fixed pulley 23 serves as a guide and direction changer, standardizing the routing of cable 22 and preventing cable 22 from swaying or abrading the well wall. The first servo motor 25 precisely controls the start, stop, and speed of the reel 24, enabling the probe and rechargeable relay module 4 to be moved and hovered at a fixed point, ensuring the rechargeable relay module 4 accurately enters the first preset position. Adjustment mechanism 5 drives the rechargeable relay module 4 to rotate horizontally within the first preset position, automatically correcting the orientation of the charging port, solving the problem of angle deviation and inability to charge normally after the rechargeable relay module 4 is moved, and improving the success rate of wireless charging docking. The entire process of moving, adjusting the attitude, and preparing for charging of the rechargeable relay module 4 is completed automatically, reducing manual intervention and adapting to unattended hydrological monitoring scenarios.

[0030] The adjustment mechanism 5 includes a connecting frame 51, a second servo motor 52, and a collar 53. The connecting frame 51 is located on the side of the main body 1 facing the accommodating space, and the second servo motor 52 is located on the connecting frame 51. The collar 53 is located between the charging mechanism 3 and the connecting frame 51, and the collar 53 is located on one side of the cable 22. Several flexible levers 54 are provided on the outer wall of the collar 53, and each flexible lever 54 is arranged at intervals along the circumference of the collar 53. The output end of the second servo motor 52 drives the connecting collar 53, and the second servo motor 52 is used to drive the collar 53 to rotate. The main controller is electrically connected to the second servo motor 52. The main controller is used to control the second servo motor 52 to drive the collar 53 to rotate when any charging relay module 4 enters the first preset position, so that each flexible lever 54 cooperates to push the charging relay module 4 located in the first preset position to rotate horizontally.

[0031] The second servo motor 52 can precisely control the direction, speed, and number of rotations of the collar 53. Together with multiple flexible guide plates 54, it smoothly drives the charging relay module 4 to rotate horizontally, enabling precise micro-adjustment of the charging relay module 4's angle and ensuring accurate alignment of the charging port with the charging mechanism 3. The flexible guide plates 54 contact and push the charging relay module 4, minimizing rigid impact and preventing scratches to the outer casing 11 of the charging relay module 4. This also avoids squeezing internal components, effectively protecting the charging relay module 4.

[0032] The adjustment mechanism 5 also includes a mounting frame 55 and a first electrically controlled telescopic column 56. The first electrically controlled telescopic column 56 is located on the side of the connecting frame 51 facing the second servo motor 52. The output end of the first electrically controlled telescopic column 56 is driven to connect to the second servo motor 52 through the mounting frame 55. The first electrically controlled telescopic column 56 is used to drive the second servo motor 52 to move closer to or away from the cable 22. The main controller is electrically connected to the first electrically controlled telescopic column 56. When any rechargeable relay module 4 enters the first preset position, the main controller controls the first electrically controlled telescopic column 56 to drive each dial plate to move closer to the rechargeable relay module 4 located in the first preset position through the mounting frame 55. When no posture adjustment is required, the electrically controlled telescopic column drives the dial plate away from the cable 22 and the relay module. The cable 22 is raised and lowered, and the module is moved without obstruction throughout the entire process, completely eliminating mechanical interference and ensuring smooth cable 22 retraction and extension.

[0033] The rechargeable repeater module 4 includes a base plate 41 and a housing 42, which are spaced apart. A through slot 44 is formed on the side of the base plate 41 facing the housing 42, extending through the base plate 41 along its length. A cable 22 passes through the through slot 44. Inside the housing 42 are a wireless charging coil, a secondary energy storage battery, a sub-controller, a repeater communication unit, and several telescopic electromagnets 43. The wireless charging coil is located on the side of the housing 42 away from the base plate 41 and is electrically connected to the secondary energy storage battery. The wireless charging coil is used when the rechargeable repeater module 4 enters the first... After the preset position is reached, the charging mechanism 3 is electrically connected to charge the secondary energy storage battery; the output end of each telescopic electromagnet 43 passes through the housing 42 to drive the connection base plate 41; the sub-controller is electrically connected to the relay communication unit, the secondary energy storage battery and each telescopic electromagnet 43 respectively, the relay communication unit is signal connected to the communicator, and the main controller is used to send the first control information to the relay communication unit of the charging relay module 4 located in the first preset position, so that each telescopic electromagnet 43 of the charging relay module 4 located in the first preset position drives the base plate 41 to approach the housing 42 and loosen the cable 22.

[0034] The base plate 41, with its through slot 44, allows direct insertion of the cable 22. Installation, disassembly, and relocation are completed simply by separating the detection probe 21 from the cable 22 and then sequentially removing each rechargeable repeater module 4. This enables rapid on-site modification and high overall maintenance efficiency. When the telescopic electromagnet 43 drives the base plate 41 to clamp the cable 22, the rechargeable repeater module 4 is firmly fixed in the designated position on the cable 22, preventing slippage and accumulation during monitoring operations, ensuring regular spacing between communication nodes and a stable communication link. The housing 42 incorporates a wireless charging coil and a secondary energy storage battery, supporting wireless charging without the need for plugging and unplugging wiring. This design is suitable for damp, open-air environments at wellheads, eliminating the risk of wiring aging and leakage, and enhancing safety.

[0035] Specifically, the main controller is used to acquire historical charging information for the previous preset time period and weather information for the next preset time period; determine the daily charging amount based on the historical charging information and weather information; acquire energy consumption data of each charging relay module 4, and determine the next charging time point based on the preset time point; acquire the energy storage information of the current main energy storage battery 33, and determine whether charging is normal at the next charging time point based on the next charging time point, daily charging amount, and energy storage information. If charging is normal at the next charging time point, normal operation is performed; if charging is not normal at the next charging time point, the difference information is determined based on the daily charging, energy storage information, and energy consumption data, and the difference information is sent to the external terminal via the communicator. By introducing weather information to predict sunlight conditions and reviewing past charging patterns with historical charging data, the power generation capacity of the photovoltaic charging panel 34 can be assessed in advance, avoiding insufficient energy storage due to a sudden drop in power generation in scenarios such as cloudy or rainy days or insufficient sunlight. This makes the charging plan more in line with the site environment and improves the rationality of energy utilization. When charging fails, the system automatically calculates the power shortage and uploads it to an external terminal. Maintenance personnel can remotely and accurately grasp the scale and cause of the power shortage, and carry out targeted on-site power replenishment and equipment maintenance, thus shortening the time required to handle the fault.

[0036] The camera 12 is also used to acquire second image information at a second preset position, which is lower than the first preset position; a fixing mechanism 6 is also provided on one side of the charging mechanism 3 inside the housing 11, which is used to grab the rechargeable relay module 4 that has entered the first preset position; the main controller is electrically connected to the fixing mechanism 6, and is used to control the fixing mechanism 6 to grab the rechargeable relay module 4 that has entered the first preset position when any rechargeable relay module 4 enters the first preset position and the wireless charging coil of the rechargeable relay module 4 is aligned with the charging mechanism 3; the main controller is used to charge the rechargeable relay module 4 that is located in the first preset position when any rechargeable relay module 4 enters the second preset position. When the power is exhausted, the fixing mechanism 6 releases the charging relay module 4 located in the first preset position according to the second image information, and then controls the driver 2 to move the charging relay module 4 located in the first preset position to above the first preset position, and at the same time drives the charging relay module 4 located in the second preset position to enter the first preset position, and sends the first control information to the charging relay module 4 located above the first preset position; the main controller is also used to control the driver 2, the fixing mechanism 6 and each telescopic electromagnet 43 of each charging relay module 4 after all charging relay modules 4 have been fully charged, so that each charging relay module 4 is set up sequentially at intervals along the length of the cable 22 according to a preset interval.

[0037] Specifically, when the fixing mechanism 6 grabs the charging relay module 4 into the first preset position, each telescopic electromagnet 43 of the charging relay module 4 located in the first preset position drives the base plate 41 away from the housing 42. This ensures that the charging relay module 4 located in the first preset position and the cable 22 are separated during the charging process, so that the cable drives the charging relay module 4 in the lower position to continue to rise and fall.

[0038] Camera 12 simultaneously monitors the first and second preset positions, providing complete visual evidence for relocation, charging, and group switching actions. It monitors the real-time status of two adjacent sets of charging repeater modules 4, ensuring that the module with the lower horizontal height among the two sets remains fixed during charging, preventing accidental slippage. The fixing mechanism 6 grips the charging repeater module 4 to be charged, counteracting cable 22 swaying and external disturbances, ensuring significantly improved charging efficiency and stability. During the charging process, the charging relay module 4 in the first preset position is fixed by the fixing mechanism 6 and charged. Simultaneously, the charging relay module 4 in the first preset position releases the cable 22 via each telescopic electromagnet 43, allowing the lower charging relay module 4 to continue moving into the second preset position. This continues until the charging relay module 4 in the first preset position is fully charged. The fixing mechanism 6 then releases the charging relay module 4 in the first preset position. The cable 22 continues to rise, and as the charging relay module 4 in the second preset position moves back to the first preset position, it lifts the original charging relay module 4 in the first preset position, completing the charging alternation. After all modules are fully charged, they are automatically re-fixed at preset intervals, restoring normal monitoring operation. No manual rearrangement of modules is required, enabling automated closed-loop operation.

[0039] As each charging repeater module 4 descends back to its working position, the fixing mechanism 6 always grabs the lowest charging repeater module 4 that is not driven by the cable 22.

[0040] An iron block 45 is provided at the end of the housing 42 away from the detection probe 21; the fixing mechanism 6 includes a second electrically controlled telescopic column 61 and an electromagnet 62. The second electrically controlled telescopic column 61 is located on the side of the housing 11 where the charging mechanism 3 is located, and the electromagnet 62 is located on the side of the second electrically controlled telescopic column 61 facing the main body 1. The second electrically controlled telescopic column 61 drives and connects to the electromagnet 62; the main controller is electrically connected to the second electrically controlled telescopic column 61 and the electromagnet 62 respectively. The main controller is used to control the second electrically controlled telescopic column 61 to drive the electromagnet 62 to magnetically attract the iron block 45 of the charging relay module 4 located in the first preset position according to the first image when any charging relay module 4 enters the first preset position.

[0041] The electromagnet 62 attracts when powered on and demagnetizes when powered off. In conjunction with the second electrically controlled telescopic column 61 moving forward and backward, it can quickly grasp and release the rechargeable relay module 4 in the first preset position. It is fixed by magnetic force without the squeezing of hard mechanical claws, thus avoiding damage to the relay module shell 11 and internal circuit.
