[0016] In summary, the present application includes at least one of the following beneficial technical effects: 1. When the monitoring tube moves to a position close to the water surface, the driving motor controls the double-headed threaded rod to rotate. Under the limiting effect of the slide bar, the two slide blocks begin to move away from each other, that is, to move the impurities on the water surface toward the two sides of the monitoring tube. After multiple reciprocating movements, most of the impurities are separated outside the two scraping nets. After the scraping nets are stopped at the position farthest from the monitoring tube, the first electromagnet is powered off, and the bending part bends toward the monitoring tube under the elastic force of the torsion spring. Therefore, under the action of the four bending parts and the two flush parts, the monitoring tube is protected, the impurities near the monitoring tube are greatly reduced, and it is also convenient to pass water into the buoyancy tank later; 2. When the monitoring tube begins to float, the third solenoid valve needs to be opened, and the sand in the upper box begins to fall from the connecting pipe into the lower box. In order to achieve the automatic resetting effect of the lower box, the monitoring board and the main body are connected by a spring. As the sand in the lower box continues to increase in weight, the weight of the lower box also continues to increase. The lower box begins to drive the first rack to move downward, and the first gear drives the second gear to rotate. The second rack begins to move toward the outside of the main body until the connecting plate moves to the specified position. If the proximity switch does not detect the triangular block, the water pump needs to be turned on at this time. Under the action of the water sprayed from the nozzle, The monitoring tube moves upward quickly, and the inclined surface of the triangular block first contacts the end of the hinge plate. As the monitoring tube continues to move upward, the triangular block lifts the hinge plate until the right-angled side of the triangular block moves above the hinge plate, and then the water pump stops working. At this time, the triangular block is completely above the hinge plate. Under the elastic force of the second torsion spring, the hinge plate returns to the top of the support plate. Due to the effect of the nozzle in this embodiment, the monitoring tube can move above its stable position in the water. Therefore, under the action of its own gravity, the connection between the bracket and the body is realized on the hinge plate of the triangular block; 3. When the monitoring tube needs to rotate, the first tube is opened and the second tube is closed, and the air pump starts to work. When the air nozzle blows out gas and the reaction force of the air is applied, the power ring drives the monitoring tube to rotate together, and the buoyancy box also starts to rotate. Therefore, most of the silt or impurities adhering to the surface of the monitoring tube or the buoyancy box are thrown out, thereby achieving the cleaning effect of the monitoring tube. When the rotation cleaning work is completed, the lifting electric push rod needs to start to descend, and the lifting electromagnet is attached to the lifting plate. First, the monitoring tube is pulled upward until the triangular block is separated from the hinged plate, and at the same time, the sand in the upper box continues to be transported to the lower box, and the lower box starts to move downward. The connecting plate is lowered, and at the same time, under the transmission action of the first gear, the second gear, the second rack and the first rack, the connecting plate continues to move away from the main body until the triangular block can slide out of the space enclosed by the main body and the hinged plate, and the monitoring tube moves downward. When the connecting plate is separated from the triangular block, the airbag is inflated and the buoyancy box is placed on the water surface. The four airbags can ensure that the buoyancy box floats stably on the water surface, and the monitoring tube continues to collect corresponding data. If the connecting plate needs to be retracted, the sand in the lower box needs to be pumped into the upper box. Under the elastic force of the spring and the transmission effect of the transmission part, the connecting plate can be recovered to the initial position. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following is combined with Figure 1-5 This application is described in further detail.

[0020] The present application embodiment discloses a Beidou dual-channel handheld device for collecting groundwater data. Figure 1-Figure 5 , a Beidou dual-channel groundwater data collection handheld device body 1, a monitoring tube 2 for using data, a data processing module, a communication module and a power module; the monitoring tube 2 is responsible for directly measuring the height of the groundwater level and doing data processing; the processing unit is responsible for receiving the electrical signal output by the sensor and converting it into a digital signal for storage and processing, usually including a microprocessor or a single-chip microcomputer, which is used to perform preliminary processing on the collected data, such as filtering, amplification, A / D conversion, etc. The processed data can be transmitted to the remote monitoring center by wire or wireless means for users to view and analyze; the communication module is a bridge between the groundwater level monitor and the remote monitoring center, supporting two modes of Beidou-3 short message + 4G dual-channel reporting and Beidou-3 short message / 4G automatic switching reporting, fully ensuring the stability of the equipment; the power supply system provides a stable power supply for the groundwater level monitor. And this device adopts an integrated design, which is easy to carry.

[0021] The main body 1 is provided with a lifting mechanism for realizing the lifting and lowering of the monitoring tube 2, a rotating mechanism for rotating the monitoring tube 2 to remove impurities, and a control mechanism for controlling the floating of the monitoring tube 2; the lifting mechanism is used to realize the rising and falling of the monitoring tube 2, and the lifting mechanism includes a lifting electric push rod 3, a lifting plate 4 and a lifting electromagnet 5, the lifting electric push rod 3 is arranged on the main body 1, the lifting plate 4 is fixed on the monitoring tube 2, the lifting electromagnet 5 moves with the output end of the lifting electric push rod 3, and the lifting electromagnet 5 adsorbs the lifting plate 4. When the monitoring tube 2 needs to be lowered to the lowest position of the groundwater, the lifting plate 4 is adsorbed by the lifting electromagnet 5, and the lifting electric push rod 3 controls the monitoring tube 2 to move downward until it moves to the lowest position, and then the monitoring tube 2 is floated to the water surface through the control mechanism, and the rotating mechanism removes impurities and silt adhering to the outside of the monitoring tube 2 after the monitoring tube 2 is rotated at high speed to ensure that the monitoring tube 2 collects data normally.

[0022] The control mechanism includes a buoyancy box 6 arranged at the bottom of the monitoring tube 2, an acceleration component for accelerating the buoyancy box 6 to float, a cleaning component for cleaning impurities on the water surface at the bottom of the monitoring tube 2, and a floating component for ensuring that the buoyancy box 6 floats stably on the groundwater surface. The buoyancy box 6 is fixed to the peripheral wall of the monitoring tube 2, that is, the top end of the monitoring tube 2 is located outside the buoyancy box 6 and the bottom end is located above the bottom of the buoyancy box 6. When the data collection of the monitoring tube 2 at the bottom of the water is completed, the lifting electromagnet 5 is separated from the lifting plate 4, and the monitoring tube 2 is controlled to float quickly to the water surface through the acceleration component; because the acceleration component uses the reaction force of water after spraying water to make the monitoring tube 2 float quickly, the buoyancy box 6 needs to enter part of the water in the initial state. In this embodiment, the amount of water in the buoyancy box 6 is set so that it will not have much influence on the buoyancy of the buoyancy box 6.

[0023] The cleaning assembly includes two sliders 7 slidably arranged at the bottom of the buoyancy box 6, a scraper net 8 movably arranged on the slider 7 and a driving part for realizing the relative movement of the two sliders 7. The scraper net 8 is in an initial horizontal state in the initial state, and the slider 7 is provided with a rotating motor for realizing the rotation of the scraper net 8. When the lifting electric push rod 3 controls the monitoring tube 2 to move to a position near the water surface, the impurities on the water surface need to be driven and isolated by the reciprocating motion of the two scrapers 8 to prevent impurities in the water from entering the buoyancy box 6; the scraper net 8 is horizontal in the initial state mainly for the convenience of carrying. When it is close to the water surface, it is necessary to control the rotation of the scraper net 8 by the rotating motor until the scraper net 8 is in a vertical state.

[0024] The driving part includes a double-headed threaded rod 46, a sliding rod 47 and a driving motor 45. The double-headed threaded rod 46 is rotatably set at the bottom of the pontoon 6, and the sliding rod 47 is fixed at the bottom of the pontoon 6. The driving motor 45 controls the rotation of the double-headed threaded rod 46. The two sliding blocks 7 are respectively screwed on the two ends of the double-headed threaded rod 46. The two sliding blocks 7 are slidably sleeved on the sliding rod 47. The length direction of the double-headed threaded rod 46 is horizontally set and set along the length direction of the pontoon 6. The length direction of the sliding rod 47 is parallel to the length direction of the double-headed threaded rod 46. The sliding rod 47 and the double-headed threaded rod 46 are located on the same side of the pontoon 6. Both the driving motor 45 and the rotating motor need to be provided with protective covers on the outside to prevent water from affecting the normal use of the driving motor 45 and the rotating motor.

[0025] The scraper 8 includes a flat portion 9 and two bent portions 10, the flat portion 9 is fixedly connected to the slider 7, the bent portions 10 are respectively arranged on both sides of the flat portion 9, and the bent portions 10 are rotatably connected to the flat portion 9 and connected through a first torsion spring 11, the flat portion 9 is also provided with a first electromagnet for adsorbing the bent portion 10, when the flat portion 9 and the bent portion 10 are in the same plane, the first torsion spring 11 is in a deformed state, and the axis of the rotating shaft between the bent portion 10 and the flat portion 9 is arranged along the width direction of the bent portion 10. That is, when the scraper net 8 rotates to a vertical state, the axial direction of the rotating shaft is in a vertical state. When the first electromagnet removes the adsorption of the bending portion 10, under the elastic force of the first torsion spring 11, the bending portion 10 begins to swing and rotate toward the monitoring tube 2. Therefore, the monitoring tube 2 is located in the middle of the two scrapers 8. While the scraper net 8 pushes the impurities on the water surface, it will also play a protective role in the subsequent data collection process of the monitoring tube 2. Of course, the bottom end of the scraper net 8 is slightly higher than the bottom end of the monitoring tube 2.

[0026] When the monitoring tube 2 moves to a position close to the water surface, the driving motor 45 controls the double-headed threaded rod 46 to rotate. Under the limiting action of the slide bar 47, the two slide blocks 7 begin to move away from each other, that is, to push the impurities on the water surface toward the two sides of the monitoring tube 2. After reciprocating many times, most of the impurities are separated outside the two scrapers 8. After the scraper 8 stops at the position farthest from the monitoring tube 2, the first electromagnet is powered off, and the bending portion 10 bends toward the monitoring tube 2 under the elastic force of the torsion spring. Therefore, under the action of the four bending portions 10 and the two flush portions 9, the monitoring tube 2 is protected, the impurities near the monitoring tube 2 are greatly reduced, and it is also convenient for the subsequent water to be passed into the buoy 6.

[0027] The acceleration component includes a water pump 12, a nozzle 13, a water inlet pipe 14, a filter 15 and a first solenoid valve 16 arranged in the floating box. A water inlet cavity is arranged in the floating box 6. The water inlet pipe 14 is used to fill the water in the water inlet cavity. The filter 15 is arranged at the opening of the water inlet pipe 14. The first solenoid valve 16 is arranged in the water inlet pipe 14. The output end of the water pump 12 is connected to the nozzle 13. The nozzle 13 sprays downward. The water inlet pipe 14 is located at the bottom of the water inlet cavity, so it is convenient for water to quickly enter the water inlet cavity. When the impurities are scraped and separated, continue to push the monitoring The measuring tube 2 moves into the water, at which time the first solenoid valve 16 is opened, and water enters the water inlet chamber from the water inlet pipe 14 until there is enough water in the water inlet chamber, then the first solenoid valve 16 is stopped, and after the monitoring tube 2 completes data collection, the adsorption relationship between the lifting plate 4 and the lifting electromagnet 5 is disconnected, and the water pump 12 is started at the same time, and the water in the water inlet chamber is sprayed out from the nozzle 13. Under the buoyancy of the float 6 and the reaction force of the water, the float 6 begins to float upward until most of the float 6 emerges from the water surface, and then the monitoring tube 2 begins to collect data on the water surface.

[0028] The rotating mechanism includes a bracket 17, a connecting component for connecting the bracket 17 to the main body 1, a monitoring component for monitoring the floating time of the monitoring tube 2, and a power component for rotating the monitoring tube. The monitoring tube 2 is rotatably connected to the bracket 17, and the bracket 17 is arranged on the outside of the monitoring tube 2. When the bracket 17 and the main body 1 have completed floating, the connecting component connects the main body 1 and the bracket 17, so that the monitoring tube 2 itself starts to rotate to remove impurities and silt on its surface.

[0029] The connecting assembly includes a connecting plate 18 slidably arranged on the body 1, a hinged plate 19 hinged on the connecting plate 18, a support plate 20 for supporting the hinged plate 19, a second torsion spring 21, a vertical plate 22 fixed on the bracket 17, and a triangular block 23. The monitoring assembly is used to control the connecting plate 18 to move to a specified position within a specified time. The hinged plate 19 is located below the connecting plate 18. The hinged plate 19 and the connecting plate 18 are connected by the second torsion spring 21. The support plate 20 is located below the hinged plate 19, and the length of the support plate 20 is smaller than the length of the hinged plate 19. The vertical plate 22 is fixed on the bracket 17, and the triangular block 23 is fixed on the vertical plate 22. The triangular block 23 is a right triangle, the inclined surface of the triangular block 23 faces the hinge plate 19, and the connecting plate 18 slides in the horizontal direction. In the initial state, the connecting plate 18 is close to the side wall of the main body 1 to avoid affecting the lifting and lowering of the monitoring tube 2 itself. Under the limiting effect of the support plate 20, the hinge plate 19 can only swing upward, and when the triangular block 23 moves to the top of the hinge plate 19, under the action of the gravity of the monitoring tube 2 itself, a right-angled side of the triangular block 23 falls above the hinge plate 19. At this time, the triangular block 23 is located in the space enclosed by the main body 1, the connecting plate 18 and the hinge plate 19, thereby achieving the connection effect between the bracket 17 and the main body 1.

[0030] The monitoring assembly includes an upper box 24, a lower box 25, a conveying part 26 for conveying sand in the lower box 25 to the upper box 24, a connecting pipe 27, a third solenoid valve 28, a monitoring plate 29, a transmission part for realizing the movement of the monitoring plate 29 and the movement of the connecting plate 18, and a proximity switch 31. The upper box 24 is arranged on the body 1, the connecting pipe 27 is used to connect the upper box 24 and the lower box 25, and the third solenoid valve 28 is arranged on the connecting pipe 27. The monitoring plate 29 is fixed on the lower box 25 and the lower box 25 is slidably arranged in the body 1. After the connecting plate 18 moves to the specified position, if the triangular block 23 is still The acceleration component is turned on when there is no contact with the proximity switch 31; in this embodiment, it is set that the movement time of the monitoring tube 2 will not be faster than the movement time of the connecting plate 18 to the specified position. Therefore, if the connecting plate 18 is extended to the specified position, the triangular block 23 does not contact the proximity switch 31. Since the proximity switch 31 is set on the side of the connecting plate 18 away from the hinge plate 19, as long as the triangular block 23 does not contact the proximity switch 31, it means that the triangular block 23 has not moved to the space enclosed by the connecting plate 18 and the hinge plate 19, and the nozzle 13 needs to start working to accelerate the floating work of the monitoring tube 2.

[0031] The transmission part includes a first rack 32, a first gear 33, a second gear 34 and a second rack 35. The first rack 32 is fixedly connected to the monitoring plate 29, the first rack 32 is slidably arranged in the main body 1 along the vertical direction, the first gear 33 is rotatably connected to the main body 1, the second rack 35 is coaxially arranged with the first gear 33, the second rack 35 is slidably arranged in the main body 1 and is connected to the connecting plate 18, the second rack 35 is meshingly connected with the second gear 34, and the first gear 33 is meshingly connected with the first rack 32; in this embodiment, the conveying part 26 can be selected to be conveyed by a pump or a screw conveyor to achieve the effect of automatic recycling of sand; the movement direction of the first rack 32 is vertically set, and the movement direction of the second rack 35 is horizontally set.

[0032] When the monitoring tube 2 starts to float up, the third solenoid valve 28 needs to be opened, and the sand in the upper box 24 starts to fall from the connecting pipe 27 into the lower box 25. In order to achieve the automatic resetting effect of the lower box 25, the monitoring plate 29 and the main body 1 are connected by a spring 30. As the sand in the lower box 25 continues to increase in weight, the weight of the lower box 25 also continues to increase. The lower box 25 begins to drive the first rack 32 to move downward, and the first gear 33 drives the second gear 34 to rotate, and the second rack 35 begins to move toward the outside of the main body 1 until the connecting plate 18 moves to the specified position. If the proximity switch 31 does not detect the triangular block 23, it is necessary to turn on the water pump 12 at this time, and the nozzle 13 sprays water. Under the condition that the monitoring tube 2 moves upward quickly, the inclined surface of the triangular block 23 first contacts the end of the hinge plate 19. As the monitoring tube 2 continues to move upward, the triangular block 23 lifts the hinge plate 19 until the right angle side of the triangular block 23 moves to the top of the hinge plate 19, and then the water pump 12 stops working. At this time, the triangular block 23 is completely above the hinge plate 19. Under the elastic force of the second torsion spring 21, the hinge plate 19 returns to the top of the support plate 20. Due to the effect of the nozzle 13 in this embodiment, the monitoring tube 2 can move to the top of its stable position in the water. Therefore, under the action of its own gravity, the triangular block 23 is on the hinge plate 19, realizing the connection between the bracket 17 and the body 1. Of course, for stability, an electromagnet can also be set between the body 1 and the connecting plate 18 for adsorption and fixation.

The interior of the power ring 36 and the power rod 37 are both provided with cavities and are connected. The air nozzle 38 is fixed at the end of the power rod 37, and the multiple air nozzles 38 blow air in the same direction. In this embodiment, four power rods 37 are selected, and the power rods 37 are evenly spaced on the peripheral wall of the power ring 36, so that during the air nozzle 38 jetting process, the power ring 36 can be uniformly stressed, which is more conducive to the power ring 36 driving the monitoring tube 2 to start rotating.

The floating assembly includes a plurality of floating plates 43, a plurality of floating motors and a plurality of air bags 44.

Similarly, the air pump 39 also needs a protective cover for protection. In this embodiment, it is ensured as much as possible that the air pump 39 and the power ring 36 enter the water for a short time or do not enter the water; the floating plate 43 is located outside the floating cavity, the area of ​​the floating plate 43 is larger than the opening size of the floating cavity, and the air bag 44 is also located in the floating cavity in the initial state, and is in a shrunk state.

[0035] When the monitoring tube 2 needs to rotate, the first tube 41 is opened and the second tube 42 is closed, the air pump 39 starts to work, and the air nozzle 38 blows out gas and under the action of the air reaction force, the power ring 36 drives the monitoring tube 2 to rotate together, and the buoyancy box 6 also starts to rotate. Therefore, the silt or impurities adhering to the monitoring tube 2 or the surface of the buoyancy box 6 are mostly thrown out, thereby achieving the cleaning effect of the monitoring tube 2 and further ensuring the normal operation of the monitoring tube 2; when the rotation cleaning work is completed, the lifting electric push rod 3 needs to start to descend, and the lifting electromagnet 5 is adhered to the lifting plate 4. First, the monitoring tube 2 is pulled upward until the triangular block 23 is separated from the hinged plate 19, and at the same time, the sand in the upper box 24 continues to be transported to the lower box 25, and the lower box 25 It starts to descend. At the same time, under the transmission action of the first gear 33, the second gear 34, the second rack 35 and the first rack 32, the connecting plate 18 continues to move away from the main body 1 until the triangular block 23 can slide out of the space enclosed by the main body 1 and the hinged plate 19, and the monitoring tube 2 moves downward. When the connecting plate 18 is separated from the triangular block 23, the airbag 44 is inflated to place the buoyancy box 6 on the water surface. The four airbags 44 can ensure that the buoyancy box 6 floats stably on the water surface, and the monitoring tube 2 continues to collect corresponding data. If the connecting plate 18 needs to be retracted, the sand in the lower box 25 needs to be pumped into the upper box 24. Under the elastic force of the spring 30 and the transmission effect of the transmission part, the connecting plate 18 can be recovered to the initial position.

[0036] The implementation principle of a Beidou dual-channel groundwater data acquisition handheld device according to an embodiment of the present application is as follows: when the monitoring tube 2 moves to a position close to the water surface, the driving motor 45 controls the double-headed threaded rod 46 to rotate. Under the limiting action of the slide bar 47, the two slide blocks 7 begin to move in directions away from each other, that is, to move the impurities on the water surface toward the two sides of the monitoring tube 2. After multiple reciprocating movements, most of the impurities are separated outside the two scraping nets 8. After the scraping nets 8 are stopped at the position farthest from the monitoring tube 2, the first electromagnet is powered off. The bending portion 10 bends toward the monitoring tube 2 under the elastic force of the torsion spring. Therefore, under the action of the four bending portions 10 and the two flush portions 9, the monitoring tube 2 is protected, the impurities near the monitoring tube 2 are greatly reduced, and it is also convenient for the subsequent passage of water into the buoyancy tank 6.

[0037] When the monitoring tube 2 starts to float up, the third solenoid valve 28 needs to be opened, and the sand in the upper box 24 starts to fall from the connecting pipe 27 into the lower box 25. In order to achieve the automatic resetting effect of the lower box 25, the monitoring plate 29 and the main body 1 are connected by a spring 30. As the sand in the lower box 25 continues to increase in weight, the weight of the lower box 25 also continues to increase. The lower box 25 begins to drive the first rack 32 to move downward, and the first gear 33 drives the second gear 34 to rotate, and the second rack 35 begins to move toward the outside of the main body 1 until the connecting plate 18 moves to the specified position. If the proximity switch 31 does not detect the triangular block 23, it is necessary to turn on the water pump 12 at this time, and the nozzle 13 sprays water. The monitoring tube 2 moves upward rapidly, and the inclined surface of the triangular block 23 first contacts the end of the hinged plate 19. As the monitoring tube 2 continues to move upward, the triangular block 23 lifts the hinged plate 19 until the right-angled side of the triangular block 23 moves to the top of the hinged plate 19, and then the water pump 12 stops working. At this time, the triangular block 23 is completely located above the hinged plate 19. Under the elastic force of the second torsion spring 21, the hinged plate 19 returns to the top of the support plate 20. Due to the effect of the nozzle 13 in this embodiment, the monitoring tube 2 can move to the top of its stable position in the water. Therefore, under the action of its own gravity, the triangular block 23 is on the hinged plate 19, thereby realizing the connection between the bracket 17 and the body 1.

[0038] When the monitoring tube 2 needs to rotate, the first tube 41 is opened and the second tube 42 is closed, the air pump 39 starts to work, and the air nozzle 38 blows out gas and under the action of the air reaction force, the power ring 36 drives the monitoring tube 2 to rotate together, and the float box 6 also starts to rotate. Therefore, the silt or impurities adhering to the surface of the monitoring tube 2 or the float box 6 are mostly thrown out, so that the monitoring tube 2 is cleaned; when the rotation cleaning work is completed, the lifting electric push rod 3 needs to start to descend, and the lifting electromagnet 5 is adhered to the lifting plate 4. First, the monitoring tube 2 is pulled upward until the triangular block 23 is separated from the hinged plate 19, and at the same time, the sand in the upper box 24 continues to be transported to the lower box 25, and the lower box 25 starts to descend. Under the transmission action of the first gear 33, the second gear 34, the second rack 35 and the first rack 32, the connecting plate 18 continues to move away from the main body 1 until the triangular block 23 can slide out of the space enclosed by the main body 1 and the hinged plate 19, and the monitoring tube 2 moves downward. When the connecting plate 18 is separated from the triangular block 23, the airbag 44 begins to be inflated, and the buoyancy box 6 is placed on the water surface. The four airbags 44 can ensure that the buoyancy box 6 floats stably on the water surface, and the monitoring tube 2 continues to collect corresponding data. If the connecting plate 18 needs to be retracted, the sand in the lower box 25 needs to be pumped into the upper box 24. Under the elastic force of the spring 30 and the transmission effect of the transmission part, the connecting plate 18 can be recovered to the initial position.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
