Description

Technical Field

[0001] The present invention relates to the technical field of liquid level measurement, and in particular to a groundwater full-automatic intelligent retractable line measurement device and method. Background Art

[0002] As an important component of water resources, groundwater plays an irreplaceable role in ensuring water for urban and rural life and production, supporting economic and social development, and maintaining a good ecological environment. However, with the development of the economy and society, the exploitation and utilization of groundwater has gradually increased, and the problems of groundwater overexploitation and pollution have become increasingly prominent. Therefore, the accurate development and effective protection of groundwater resources must rely on long-term groundwater monitoring to timely and comprehensively grasp its dynamic changes. Traditional groundwater monitoring methods have many shortcomings, such as time-consuming and labor-intensive, large amounts of redundant data, poor monitoring effectiveness, and large network transmission limitations. These problems limit the efficiency and accuracy of groundwater monitoring and cannot meet the current needs for scientific management and protection of groundwater resources. In order to solve these problems, modern intelligent technologies have been widely used in the field of groundwater monitoring.

[0003] For example, the patent application with the prior art publication number CN118776629A discloses a fully automatic portable groundwater level well depth measuring instrument, which relates to the field of groundwater level well depth measurement technology, including a mounting frame and a water level well, and also includes a measuring part, wherein the measuring part, the locking part and the tension control part include a take-up roller rotatably mounted on the mounting frame, and a protective cover is wound on the take-up roller. During the measurement process, the measuring instrument realizes automatic measurement without manual operation, reduces labor intensity, improves measurement efficiency, and avoids inaccurate measurement caused by groundwater flow and self-twisting or tilting of the tape measure. At the same time, the tension of the tape measure itself can be adjusted in real time to ensure that the tension of the tape measure is within the normal extension range, effectively improving the accuracy of measurement.

[0004] Compared with previous technical solutions, this innovation uses a precisely designed tension control unit to enable the measuring instrument to adjust the tension state of the tape measure in real time and accurately, effectively avoiding the problem of self-rotation distortion of the protective cover due to uneven tension, thereby greatly improving the accuracy and stability of the measurement. However, in actual application, after the measurement task is completed, the existing technology needs to first carefully read the small scale values ​​on the tape measure. This process not only requires extremely high visual concentration and patience, but is also very easy to misread due to factors such as visual fatigue or insufficient light. Next, they also need to measure and record the vertical distance between the steering wheel 2 and the outrigger. This step is also cumbersome and time-consuming, because it not only involves the use of precise measuring tools, but also requires complex spatial imagination and mathematical calculations. Such an operation process not only increases the time cost of the measurement work, but more importantly, due to the excessive involvement of human factors in the whole process, such as visual errors in reading, thinking jumps in calculations, etc., may lead to deviations in the final measurement results, thereby affecting the accuracy of subsequent data analysis and the scientific nature of decision-making. To this end, this application proposes a measurement device and method for fully automatic intelligent retractable line for groundwater. Summary of the invention

[0015] The present invention also provides a groundwater fully automatic intelligent retractable line measurement method, comprising the following steps:

[0016] S1. When in use, first open the hatch so that the support handle pulls the crank to tilt, thereby driving the fixing frame to be placed above the hatch, and then operate the driving assembly to convey the wire so that the probe falls in the well;

[0017] S2. When the wire is transported, the length measuring assembly will be operated to know the depth of the probe;

[0018] S3, when the probe falls and contacts the water surface for the first time, the test assembly will be operated to detect the contact with the water surface;

[0019] S4. Then check the length measuring component to know the well water depth.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The hatch can effectively seal the interior of the water level well depth meter and protect the internal components from the external environment. When the wire needs to be released for testing, the opening of the hatch can link the support handle and the crank to tilt the crank to provide space for the release of the wire. The operation is easy. The cooperation between the conductor roller and the extrusion roller and the close cooperation between the two ensure the stable transportation of the wire and avoid the jamming or falling off of the wire during transportation, thereby improving the accuracy and stability of the measurement. The meshing of the driving gear and the driven gear: the driving motor drives the active rotating rod to rotate, thereby driving the extrusion roller and the driving gear to rotate. Due to the meshing relationship between the driving gear and the driven gear, the conductor roller will also rotate, thereby realizing the smooth transportation of the wire. The design of the winding roller allows the wire to be neatly wound on it when not in use, thereby avoiding the disorder of the wire and facilitating the storage and transportation of the wire.

[0022] By recording the rotation of the rotating gear in real time, the encoder can accurately calculate the number of rotations of the winding roller, thereby knowing the length of the released wire. This real-time performance is crucial for monitoring groundwater levels and can ensure the accuracy and timeliness of data. The meshing of the rotating gear with the inner disc teeth: This design ensures the accurate measurement of the released length of the wire. The rotating gear rotates with the rotation of the winding roller, and its rotation angle is proportional to the released length of the wire. Therefore, the encoder can accurately record and calculate the released length of the wire. The close cooperation between the length measurement component and the winding roller, drive component and other components realizes the automatic transportation, accurate measurement and stable recovery of the wire. This synergy not only improves the measurement efficiency, but also ensures the accuracy and reliability of the measurement data. Through the integration of the encoder and the communication component, the measurement data can be transmitted to the remote monitoring center in real time, realizing remote monitoring and data analysis of the groundwater level.

[0023] When the probe contacts the water surface, the float rises due to the buoyancy, driving the top rod and the cone upward, so that the second metal trigger piece contacts the first metal trigger piece, forming a closed loop circuit and accurately triggering the electrical signal. This design ensures that the electrical signal can be generated immediately when the water surface is contacted, providing an accurate time point for subsequent measurements. The drain allows well water to enter during the probe's fall, preparing for the subsequent downward movement of the weighted part and water pressure measurement. The piston piece and the weighted part work together to form a closed space for measuring water pressure. When the well water pours into the probe and applies pressure to the weighted part, the weighted part moves downward, driving the transmission metal sheet into the top screw groove to complete the transmission of the second layer of electrical signals. This multiple insurance design ensures the accuracy and reliability of the measurement. After the measurement, the reset spring provides reset power for the float and the top rod, ensuring that the probe can be reused. The roller rolls in the transmission groove to drive the sliding block to move, thereby pushing the curved rod and the weighted part upward to discharge the internal water. This design not only realizes the automatic reset and drainage functions of the probe, but also improves the durability and reusability of the probe. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Example 1: Please refer to Figure 1 , Figure 2 as well as Figure 4 The present invention provides a technical solution: a groundwater fully automatic intelligent retractable line measuring device, comprising a water level well depth measuring instrument 100 with a communication component 104, a hatch 103 hinged at the bottom of the water level well depth measuring instrument 100, a rubber seat 102 fixedly connected to the bottom of the water level well depth measuring instrument 100, a handle 101 fixedly connected to the top of the water level well depth measuring instrument 100, one side of the hatch 103 is rotatably connected to two support handles 201, the tops of the two support handles 201 are rotatably connected to cranks 200 rotatably connected to the inside of the water level well depth measuring instrument 100, and the interior of the water level well depth measuring instrument 100 can be effectively blocked by setting the hatch 103 At the same time, in cooperation with the support handle 201 and the crank 200, the crank 200 can be pulled to tilt so as to facilitate the release of the wire 300 for detection. The tops of the two cranks 200 are respectively fixedly connected with fixed frames 202, and the two fixed frames 202 are rotatably connected with a fixed rod 203. The middle end of the fixed rod 203 is rotatably connected with a first rotating rod 204. A winding roller 301 is arranged inside the water level and well depth measuring instrument 100, and the outer surface of the winding roller 301 is wound with the wire 300. The outer surface of the first rotating rod 204 is provided with a driving component for driving the wire 300 to move. By setting the driving component, the wire 300 can be effectively driven to be transported for detection.

[0042] For further information, see Figure 3 , Figure 7 as well as Figure 8 The driving component includes a wire roller 208 fixedly connected to the middle end of the first rotating rod 204, and the outer surface of the fixed rod 203 is fixedly connected to two supports 205, and an active rotating rod 206 is connected to the two supports 205 for common rotation, and the outer surface of the active rotating rod 206 is fixedly connected to an extrusion roller 207 adapted to the wire roller 208, and the wire 300 passes between the extrusion roller 207 and the wire roller 208. By setting the wire roller 208 to cooperate with the extrusion roller 207, the wire 300 can be squeezed to transport the wire 300, ensuring that the wire 300 passes stably, and the fixed rod 203 is fixedly connected to the support 205 so that the active rotating rod 206 rotates to drive the wire 300.

[0043] Among them, a driving motor 211 is fixedly connected to one side of a support 205, the output end of the driving motor 211 is fixedly connected to the active rotating rod 206, the outer surface of the squeezing roller 207 is fixedly connected to the driving gear 210, and the outer surface of the wire roller 208 is fixedly connected to the driven gear 209 meshing with the driving gear 210. By setting the driving gear 210 and the driven gear 209 to cooperate, the wire roller 208 and the squeezing roller 207 are reversed to realize the transportation of the wire 300.

[0044] Specifically, when in use, first open the hatch 103 so that the support handle 201 pulls the crank 200 to tilt, thereby driving the fixed frame 202 to be placed above the hatch 103, and then control the drive motor 211 to drive the active rotating rod 206 to rotate so that the squeezing roller 207 rotates, thereby driving the active gear 210 to rotate, and the active gear 210 is engaged with the driven gear 209 to drive the wire roller 208 to rotate, so that the wire 300 between the wire roller 208 and the squeezing roller 207 is transported, thereby transporting the probe 400 to fall in the well.

[0045] In summary, the hatch 103 can effectively seal the interior of the water level well depth measuring instrument 100, protecting the internal components from the external environment. When the wire 300 needs to be released for testing, the opening of the hatch 103 can link the support handle 201 and the crank 200 to tilt the crank 200 to provide space for the release of the wire. The operation is simple. The cooperation between the wire roller 208 and the squeezing roller 207, and the close cooperation between the two ensure the stable transportation of the wire 300, avoid the wire from getting stuck or falling off during the transportation process, and improve the measurement efficiency. The accuracy and stability of the winding roller 301 are achieved by the meshing of the driving gear 210 and the driven gear 209: the driving motor 211 drives the driving rotating rod 206 to rotate, thereby driving the squeezing roller 207 and the driving gear 210 to rotate. Due to the meshing relationship between the driving gear 210 and the driven gear 209, the wire roller 208 will also rotate, thereby achieving smooth transportation of the wire 300. The design of the winding roller 301 allows the wire 300 to be neatly wound on it when not in use, thereby avoiding the disorder of the wires and facilitating the storage and transportation of the wires.

[0046] Example 2: Please refer to Figure 5 , Figure 6 as well as Fig. 9The present invention also provides a technical solution, which is different from the technical solution of the first embodiment: a groundwater fully automatic intelligent wire reel measuring device, a length measuring component for detecting the release length of the wire 300 is arranged on one side of the reel 301, and the length measuring component includes a support rod 302 fixedly connected to the inside of the water level well depth measuring instrument 100, a second rotating rod 304 for fixing the reel 301 is arranged at the middle end of the support rod 302, a connecting handle 309 is fixedly connected to the outer surface of the second rotating rod 304, a ring disk 307 is arranged on the outer surface of the connecting handle 309, and an inner disk tooth 308 is fixedly connected to the inner surface of the ring disk 307, and a connecting rod 308 is fixedly connected to the inner surface of the ring disk 307. The top of the connecting handle 309 is rotatably connected to a rotating gear 311 that meshes with the inner disc teeth 308, and one side of the connecting handle 309 is fixedly connected to an encoder 312 whose output end is fixedly connected to the rotating gear 311. By setting up a length measuring component, the released length of the wire 300 can be checked in real time, wherein the rotation of the connecting handle 309 causes the rotating gear 311 to cooperate with the inner disc teeth 308 to produce self-rotation, and the rotation of the rotating gear 311 will be transmitted to the encoder 312, so that it can know the rotation angle of the rotating gear 311, thereby calculating the number of rotations of the winding roller 301 and knowing the released length of the wire 300.

[0047] Furthermore, both ends of the second rotating rod 304 are rotatably connected to fixed shells 303, and the two fixed shells 303 are fixedly connected to the support rod 302, and the interior of the fixed shells 303 is spirally provided with a spring 305 adapted to the second rotating rod 304, and one side of one fixed shell 303 is fixedly connected with a bracket 306 for supporting the ring disk 307, and the bracket 306 can support the ring disk 307. By setting the spring 305, the second rotating rod 304 can store power so that the winding roller 301 can retract the wire 300 when the wire 300 is retracted.

[0048] Specifically, when the wire 300 is transported, the winding roller 301 will rotate, thereby driving the second rotating rod 304 to rotate. At this time, the rotation of the second rotating rod 304 will drive the spring 305 in the fixed shell 303 to rotate and accumulate force. At the same time, when the second rotating rod 304 rotates, it will drive the connecting handle 309 to rotate together and drive the rotating gear 311 to slide along the inner wall of the ring disk 307, so that the rotating gear 311 engages with the inner disk teeth 308 and drives the rotating gear 311 to rotate. At this time, the encoder 312 will record the rotation of the rotating gear 311 to know the depth of the probe 400.

[0049] In summary, the encoder 312 can accurately calculate the number of rotations of the winding roller 301 by recording the rotation of the rotating gear 311 in real time, so as to know the length of the released wire 300. This real-time performance is crucial for the monitoring of groundwater level, which can ensure the accuracy and timeliness of the data. The meshing of the rotating gear 311 with the inner disc teeth 308: This design ensures the accurate measurement of the released length of the wire 300. The rotating gear 311 rotates with the rotation of the winding roller 301, and its rotation angle is proportional to the released length of the wire 300. Therefore, the encoder 312 can accurately record and calculate the released length of the wire. The close cooperation between the length measuring component and the winding roller 301, the driving component and other components realizes the automatic transportation, accurate measurement and stable recovery of the wire. This synergy not only improves the measurement efficiency, but also ensures the accuracy and reliability of the measurement data. Through the integration of the encoder 312 and the communication component 104, the measurement data can be transmitted to the remote monitoring center in real time, realizing the remote monitoring and data analysis of the groundwater level.

A metal trigger sheet 405 and a weight column 401 are fixedly connected to the bottom of the probe 400. A float 408 is provided at the bottom of the probe 400. A top rod 407 is fixedly connected to the top of the float 408. The top of the top rod 407 extends to the inside of the probe 400 and is fixedly connected to the cone 406. A reset spring 409 is sleeved on the outer surface of the top rod 407 for its own reset. By setting up a detection component, the probe 400 can transmit an electrical signal to the sensor 310 when it contacts the water surface, and at the same time, it cooperates with the length measuring component for measuring the length of the wire 300 to know the water depth.

[0051] For further information, see Fig.11 , Fig.12 as well as Fig.15The outer surface of the probe 400 is provided with a plurality of drain ports 402, the bottom of the cone 406 is fixedly connected with a piston plate 410 adapted to the inside of the probe 400, the outer surface of the push rod 407 is slidably connected with a weight-bearing piece 411 adapted to the inside of the probe 400 at the top, and a plurality of transmission metal sheets 412 are evenly and fixedly connected to the bottom of the weight-bearing piece 411, a circuit 413 is connected between the cone 406 and the weight-bearing piece 411, and the inside of the probe 400 is provided with a top screw groove matched with the plurality of transmission metal sheets 412, and two layers of insurance can be achieved by setting the matching of the transmission metal sheet 412 and the top screw groove, wherein the transmission of the electrical signal needs to ensure that the first metal trigger sheet 404 is in contact with the second metal trigger sheet 405, and the transmission metal sheet 412 is in contact with the top screw groove, which may transmit the electrical signal to the sensor 310.

[0052] For further information, see Fig.13 , Fig.14 as well as Fig.15 The probe 400 is fixedly connected to a fixed plate 414, and the top of the fixed plate 414 is slidably connected to a plurality of sliding blocks 415 in a divergent shape along the center thereof. Both sides of the plurality of sliding blocks 415 are rotatably connected to a bent rod 416 rotatably connected to the bottom of the weight-bearing member 411, and the interiors of the plurality of sliding blocks 415 are fixedly connected to a tension spring 417 fixedly connected to the interior of the probe 400. The inclined surfaces of the plurality of sliding blocks 415 are provided with transmission grooves 419, and the outer surface of the top rod 407 is rotatably connected to a plurality of rollers 418 adapted to the transmission grooves 419, and the float 408 is subjected to water pressure to move upward. At this time, the well water passes through the multiple drain ports 402 and enters the weight-bearing part 411 and the piston plate 410, squeezing the transmission metal sheet 412 into the top screw groove to complete the transmission of the electrical signal. At the same time, when the probe 400 is taken out, the float 408 is reset by the reset spring 409, so that the roller 418 on the outer surface of the top rod 407 contacts the transmission groove 419 and drives the sliding block 415 to move, so that the sliding block 415 pushes the curved rod 416 to move and push the weight-bearing part 411 to move upward, thereby discharging the water in the weight-bearing part 411 and the piston plate 410, which is convenient for subsequent multiple uses.

[0053] It is worth mentioning that one end of the wire 300 away from the probe 400 is fixedly connected to the inside of the connecting handle 309, and one side of the connecting handle 309 is fixedly connected to a sensor 310 connected to one end of the wire 300, wherein the sensor 310 is electrically connected to the drive motor 211 so that the sensor 310 controls the start and stop of the drive motor 211 when receiving an electrical signal.

[0054] Specifically, when the probe 400 falls and contacts the water surface for the first time, the float 408 will be driven to float up and the push rod 407 will be driven to move up. At this time, the push rod 407 will pass through the fixed plate 414 and the weight-bearing member 411 to push the cone 406 to move up, so that the cone 406 moves up and drives the second metal triggering piece 405 to contact the first metal triggering piece 404, thereby forming a closed loop. At the same time, when the counterweight column 401 continues to move downward, the well water will be poured into the interior of the probe 400 through the drain port 402. The well water continuously pouring into the interior of the probe 400 will press on the top of the weight-bearing member 411, thereby squeezing the weight-bearing member 411. The heavy part 411 moves downward and drives the multiple curved rods 416 to tilt, so that the multiple sliding blocks 415 are close to each other, and then drives the multiple transmission metal sheets 412 to be placed in the multiple top screw grooves. The transmission of electrical signals is realized by placing the multiple transmission metal sheets 412 in the multiple top screw grooves. The electrical signal is transmitted through the probe 400 through the wire 300 to the inside of the sensor 310. At this time, the sensor 310 operates the drive motor 211 to stop rotating and stop the wire 300 to fix the depth of the probe 400. At this time, the data of the encoder 312 can be used to know the depth of the probe 400, that is, the groundwater depth.

[0055] In summary, when the probe 400 contacts the water surface, the float 408 rises due to the buoyancy, driving the top rod 407 and the cone 406 to move upward, so that the second metal trigger sheet 405 contacts the first metal trigger sheet 404, forming a closed-loop circuit and accurately triggering the electrical signal. This design ensures that the electrical signal can be generated immediately when the water surface is contacted, providing an accurate time point for subsequent measurements. The drain 402 allows well water to enter during the falling process of the probe 400, preparing for the subsequent downward movement of the weight-bearing part 411 and water pressure measurement. The piston sheet 410 and the weight-bearing part 411 work together to form a closed space for measuring water pressure. When the well water pours into the probe 400 and applies pressure to the weight-bearing part 411, the weight-bearing part moves downward, driving the transmission metal sheet 412 to enter the top screw groove, completing the transmission of the second layer of electrical signals. This multiple insurance design ensures the accuracy and reliability of the measurement. After the measurement is completed, the reset spring 409 provides reset power for the float 408 and the top rod 407 to ensure that the probe 400 can be reused. The rolling of the roller 418 in the transmission groove 419 drives the sliding block 415 to move, thereby pushing the curved rod 416 and the weight-bearing member 411 upward to discharge the internal water. This design not only realizes the automatic reset and drainage functions of the probe, but also improves the durability and reusability of the probe.

[0056] Example 4: Please refer to Figures 1 to 15 The present invention also provides a technical solution, which is different from the technical solution of the above embodiment: a groundwater fully automatic intelligent retractable line measurement method, comprising the following steps:

[0057] S1. When in use, first open the hatch 103 so that the support handle 201 pulls the crank 200 to tilt, thereby driving the fixing frame 202 to be placed above the hatch 103, and then operate the driving motor 211 to drive the active rotating rod 206 to rotate, so that the squeezing roller 207 rotates, thereby driving the active gear 210 to rotate, and the active gear 210 is meshed with the driven gear 209 to drive the wire roller 208 to rotate, so that the wire 300 between the wire roller 208 and the squeezing roller 207 is transported, thereby transporting the probe 400 to fall in the well;

[0058] S2. When the electric wire 300 is transported, the winding roller 301 will rotate, thereby driving the second rotating rod 304 to rotate. At this time, the rotation of the second rotating rod 304 will drive the spring 305 in the fixed shell 303 to rotate and store power. At the same time, when the second rotating rod 304 rotates, it will drive the connecting handle 309 to rotate together and drive the rotating gear 311 to slide along the inner wall of the ring disk 307, so that the rotating gear 311 is meshed with the inner disk teeth 308 and drives the rotating gear 311 to rotate. At this time, the encoder 312 will record the rotation of the rotating gear 311 to know the depth of the probe 400;

[0059] S3. When the probe 400 falls and contacts the water surface for the first time, it will drive the float 408 to float up and drive the push rod 407 to move up. At this time, the push rod 407 will pass through the fixed plate 414 and the weight-bearing member 411 to push the cone 406 to move up, so that the cone 406 moves up and drives the second metal triggering piece 405 to collide with the first metal triggering piece 404, thereby forming a closed loop. At the same time, when the counterweight column 401 continues to move downward, the well water is poured into the interior of the probe 400 through the drain port 402. The well water continuously pours into the interior of the probe 400 and exerts pressure on the top of the weight-bearing member 411, thereby squeezing the weight-bearing member 411 to move downward and driving the multiple curved rods 416 to tilt, so that the multiple sliding blocks 415 are close to each other, and then drive the multiple transmission metal sheets 412 to be placed in the multiple top screw grooves;

[0060] S4. The transmission of electrical signals is achieved by placing multiple transmission metal sheets 412 in multiple top wire grooves. The electrical signals are transmitted through the probe 400 from the wire 300 to the inside of the sensor 310. At this time, the sensor 310 operates the drive motor 211 to stop rotating and stop the wire 300 to fix the depth of the probe 400. At this time, the data of the encoder 312 can be used to know the depth of the probe 400, that is, the groundwater depth.
