The system in this application is a fully automatic groundwater monitoring recorder that integrates water level and temperature data collection, storage, processing and transmission. It has the function of simultaneously monitoring water level and water temperature data. The product has a built-in data collector to realize internal analog-to-digital conversion.

When the transmission box is in a hollow state, it cannot drive the ring knife to move downward, or the movement speed is slow. In order to enable the transmission box to smoothly drive the ring knife to clean the outside of the shell, the first solenoid valve is opened, and water continuously enters the transmission box until the water sensor at the top recognizes that the transmission box is full of water. At this time, the first solenoid valve is stopped, and the first electromagnet and the ring knife are released, and the ring knife begins to move downward under the gravity of the transmission box; in order to accelerate the cleaning effect of the shell and ensure that the water level sensor quickly enters the working state, the second solenoid valve is opened, and the edible salt in the weight-increasing box enters the transmission box. Since the edible salt can be quickly dissolved in the water in the transmission box and will not have a significant impact on the volume of the transmission box, and at the same time, the weight of the water in the transmission box increases, thereby achieving the effect of further increasing the weight of the transmission box without expanding the volume of the transmission box. As the weight of the weight-increasing box increases, the downward speed of the ring knife increases, thereby accelerating the rapid cleaning of the silt on the outer wall of the shell; 3. When it is necessary to increase the buoyancy of the floating box and the transmission box, open the third solenoid valve. Since the quicklime reaction requires less water content, after the water reacts with the quicklime in the non-woven bag, the quicklime releases a large amount of heat and produces carbon dioxide. Since the transmission box and the floating box are coated with thermal insulation materials, the heat loss caused by heat transfer between the transmission box and the floating box is reduced. At this time, the airbag overcomes the water pressure and begins to expand. As the airbag expands, the buoyancy of the floating box and the transmission box is greatly increased. Under the elastic force of the first spring and the buoyancy of the airbag, the ring knife moves quickly to the position abutting the trigger rod, and the top of the trigger rod abuts the proximity switch, and the first electromagnet adsorbs the ring knife.

[0019] The following is combined with Figure 1-3 This application is described in further detail.

[0020] The present application embodiment discloses a Beidou dual-channel groundwater monitoring system. Figure 1-Figure 3, a Beidou dual-channel groundwater monitoring system includes a housing 1, a water level sensor 2, a data acquisition and processing module, a communication module and a power module; the water level sensor 2 is responsible for directly measuring the height of the groundwater level; the data acquisition and processing unit is responsible for receiving the electrical signal output by the sensor and converting it into a digital signal for storage and processing. This unit usually includes a microprocessor or a single-chip microcomputer for preliminary processing of the collected data, such as filtering, amplification, A / D conversion, etc. The processed data can be transmitted to a remote monitoring center via wired 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.

[0021] It also includes a cleaning device for cleaning the sludge on the shell 1; the power of the cleaning device is also provided by the power module; the cleaning device includes an identification mechanism for identifying the sludge situation and a scraping mechanism for scraping the sludge; the identification mechanism is used to identify the sludge, that is, if it is observed that there is a lot of sludge in the water and it is easy to adhere, the scraping mechanism is used to clean the sludge on the shell 1; the scraping mechanism includes a ring knife 3 slidably arranged on the outside of the shell 1, a transmission component for controlling the reciprocating motion of the ring knife 3, and a trigger component for identifying whether the ring knife 3 is moving. The ring knife 3 is sleeved on the outside of the shell 1, and the thickness of the ring knife 3 gradually decreases along the outer wall toward the inner wall. The tip of the ring knife 3 fits with the outer wall of the shell 1. Under the action of the transmission component, the ring knife 3 scrapes the sludge adhered to the shell 1, thereby achieving the effect of cleaning the sludge on the shell 1. The trigger component is used to identify the movement of the ring knife 3. The initial position of the ring knife 3 is located at the upper end of the shell 1, and it mainly monitors two states, one is whether the ring knife 3 moves downward from the initial position, and the other is whether the ring knife 3 moves from the bottom to the upper end of the shell 1.

[0022] The trigger assembly includes a trigger box 25 fixed on the shell 1, a trigger rod 26, a first electromagnet 27 and a proximity switch 28. The trigger box 25 is provided with a trigger hole 29. The trigger rod 26 is elastically arranged in the trigger hole 29. The first electromagnet 27 is fixed on the trigger box 25 and is used to adsorb the ring knife 3. The bottom end of the trigger rod 26 abuts against the upper end surface of the ring knife 3. The trigger rod 26 slides and fits in the trigger hole 29. The top end of the trigger rod 26 abuts against the proximity switch 28. The proximity switch 28 is electrically connected to the second solenoid valve 10. The proximity switch 28 is electrically connected to the third solenoid valve 20. The trigger hole 29 is provided with a limiting groove. The side wall of the trigger rod 26 is fixedly connected with a limiting block. The limiting block moves in the limiting groove, and the end of the limiting block is in contact with the limiting groove. An elastic member is fixedly connected between the inner walls of the corresponding ends of the groove to realize the elastic setting movement of the trigger rod 26 in the trigger hole 29, and during the movement of the trigger rod 26, the trigger rod 26 also keeps sealing the side wall of the limiting groove, so that water will not only not enter the trigger hole 29, but also will not enter the limiting groove; when the ring knife 3 is in the initial state, the trigger rod 26 is in contact with the proximity switch 28, and the elastic member is in a compressed state. The elastic member can also be a spring. The first electromagnet 27 now adsorbs and fixes the ring knife 3. When the first electromagnet 27 releases the ring knife 3 and the ring knife 3 moves downward, the trigger rod 26 moves downward under the elastic force of the elastic member, and the top of the trigger rod 26 is separated from the proximity switch 28.

[0023] The transmission assembly includes a transmission box 4, a first solenoid valve 5, a water sensor 6, a weight-adding part for adding weight to the transmission box 4, and a rising part for raising the transmission part. The transmission box 4 is provided with a water inlet 7 near the side wall of the bottom wall, the first solenoid valve 5 is provided at the water inlet 7, the water sensor 6 is installed in the transmission box 4 and is located at the top of the transmission box 4, the transmission box 4 is fixedly connected to the outer wall of the ring knife 3, and the transmission box 4 is made of a material with low buoyancy; the transmission box 4 is at the upper end of the shell 1 in the initial position, that is, it is adsorbed on the trigger box 25 by the first electromagnet 27, and the transmission box 4 is at this time It is also in a cavity state. Due to the different water quality conditions and the size of the transmission box 4, the transmission box 4 cannot drive the ring knife 3 to move downward when it is in the cavity state, or the movement speed is slow. In order to enable the transmission box 4 to smoothly drive the ring knife 3 to clean the outside of the shell 1, the first solenoid valve 5 is opened, and water continuously enters the transmission box 4 until the water sensor 6 at the top recognizes that the transmission box 4 is full of water. At this time, the first solenoid valve 5 is stopped, and the first electromagnet 27 and the ring knife 3 are released. The ring knife 3 starts to move downward under the gravity of the transmission box 4.

[0024] The weight-increasing part includes a weight-increasing box 8, a weight-increasing tube 9 and a second solenoid valve 10. The weight-increasing box 8 is filled with edible salt. The second solenoid valve 10 is installed on the weight-increasing tube 9. The other end of the weight-increasing tube 9 extends into the transmission box 4. The weight-increasing box 8 is fixed on the shell 1. The weight-increasing tube 9 is set as a hose. Of course, other salts can also be used for edible salt, as long as they can be quickly dissolved and can increase weight. In order to accelerate the cleaning effect of the shell 1 and ensure that the water level sensor 2 quickly enters the working state, the second solenoid valve 10 is opened, and the edible salt in the weight-increasing box 8 enters the transmission box 4. Since the edible salt can be quickly dissolved in the water in the transmission box 4 and will not have a significant impact on the volume of the transmission box 4, at the same time, the weight of the water in the transmission box 4 increases, thereby achieving the effect of further increasing the weight of the transmission box 4 without expanding the volume of the transmission box 4. As the weight of the weight-increasing box 8 increases, the downward speed of the ring knife 3 is accelerated, thereby accelerating the rapid cleaning of the sludge on the outer wall of the shell 1.

[0025] The rising part includes a first spring 11, a slider 12, a rising solenoid valve 13, a lifting and lowering extrusion plate 14 arranged in the transmission box 4, a one-way valve 15 and a floating group for increasing the buoyancy of the transmission box 4. The shell 1 is provided with a slide groove for the sliding of the slider 12. Both ends of the slide groove along the vertical direction are closed. The two ends of the spring are respectively fixedly connected to one end of the slider 12 and the inner wall of the corresponding end of the slide groove. The water sensor 6 is located on the side wall of the transmission box 4 close to the top and will not interfere with the movement of the extrusion plate 14. The transmission box 4 is provided with a rising port 16. The rising solenoid valve 13 is arranged at the rising port 16 and the one-way valve 15 is arranged in the rising port 16. The extrusion plate 14 squeezes the water in the transmission box 4 out of the rising port 16. The lifting and lowering of the extrusion plate 14 can be achieved by an electric push rod, but a protective box for protecting the electric push rod needs to be provided in the transmission box 4. The opening size of the slide groove is smaller than the size inside the slide groove to minimize siltation. The possibility of mud entering the chute, in this embodiment, it is set that the silt in the chute will not affect the normal movement of the first spring 11; when the ring knife 3 moves to the bottom of the shell 1, the first spring 11 is squeezed and deformed. At this time, the transmission box 4 and the ring knife 3 need to move together, so that the outer wall of the shell 1 can be cleaned, and the ring knife 3 also needs to move to the initial position, and open the rising solenoid valve 13 on the rising port 16. Due to the water pressure, the water in the transmission box 4 will not flow out of the transmission box 4. At this time, the squeezing plate 14 is required to squeeze the water in the transmission box 4. The squeezing plate 14 pushes the water out of the rising port 16 and due to the one-way valve 15, the water can only flow out of the transmission box 4 and cannot flow into the transmission box 4 from the rising port 16. At this time, after the transmission box 4 is completely squeezed out, the rising solenoid valve 13 is closed. Due to the reduction in the weight of the transmission box 4, the transmission box 4 moves upward under the elastic force of the first spring 11.

[0026] The floating group includes a floating box 17, a non-woven bag 18, an airbag 19 and a third solenoid valve 20. The floating box 17 is fixed on the outer wall of the transmission box 4. The inner wall of the floating box 17 is set as a cavity. The bottom wall of the floating box 17 is provided with an annular groove adapted to the non-woven bag 18. The non-woven bag 18 is filled with quicklime. The depth of the annular groove is greater than the size of the non-woven bag 18. The floating box 17 is provided with a floating tube connected to the annular groove. The third solenoid valve 20 cooperates with the floating tube. The airbag 19 is fixed on the outer peripheral wall of the floating box 17. The floating box 17 is provided with a plurality of air holes 21. The air holes 21 are connected to the airbag 19. The floating box 17 is set to be annular. The connection between the airbag 19 and the floating box 17 can be achieved by bolts or glue. The opening of the airbag 19 is connected to the side wall of the floating box 17 with the air holes 21. When it is necessary to increase the buoyancy of the floating box 17 and the transmission box 4, the third solenoid valve 20 is turned on. Valve 20, since the water content required for the quicklime reaction is small, the weight of the water entering the floating box 17 can be ignored, and in this embodiment, it is necessary to ensure that the water entering the annular groove will not overflow from the annular groove. After the water reacts with the quicklime in the non-woven bag 18, the quicklime releases a large amount of heat and produces carbon dioxide. Since the transmission box 4 and the floating box 17 are coated with thermal insulation materials, the heat loss caused by heat transfer between the transmission box 4 and the floating box 17 is reduced. In this embodiment, the size of the floating box 17 is set to be small and the water pressure is small. At this time, the airbag 19 overcomes the water pressure and begins to expand. As the airbag 19 expands, the buoyancy of the floating box 17 and the transmission box 4 is greatly increased. Under the elastic force of the first spring 11 and the buoyancy of the airbag 19, the ring knife 3 moves quickly to the position abutting against the trigger rod 26, and the top of the trigger rod 26 abuts against the proximity switch 28, and the first electromagnet 27 adsorbs the ring knife 3.

[0027] The floating group also includes a phase change tube 22 filled with phase change material, which is arranged on the upper side wall of the floating box 17, and the floating box 17 and the transmission box 4 are provided with a phase change hole 24 for the movement of the phase change tube 22, and the phase change tube 22 is slidably adapted in the phase change hole 24. The end of the phase change tube 22 close to the transmission box 4 is fixedly connected with an insulation tube, and the insulation tube is located at the end of the phase change hole 24 close to the transmission box 4 in the initial position. A phase change electric push rod 23 for controlling the movement of the transmission box 4 is provided in the floating box 17. The transmission box 4 and the floating box 17 are coated with thermal insulation materials. In the initial state, most of the phase change tube 22 is located in the floating box 17. After absorbing the heat in the floating box 17, it is necessary to pull most of the phase change tube 22 into the phase change hole 24. The main function of the phase change tube 22 is to heat the water in the transmission box 4, thereby accelerating the mixing of edible salt in the water. After the weight of the water in the transmission box 4 is increased, the sludge can be quickly cleaned during the downward movement of the ring knife 3.

[0028] The outer shell is fixedly connected to a rack 39, and the outer shell is also rotatably connected to a gear 40. The rack 39 moves in a vertical direction, and the gear 40 is meshed with the rack 39. The transmission box 4 is fixedly connected to a third electromagnet 41, and the third electromagnet 41 is adsorbed on the rack 39. The gear 40 is coaxially fixedly connected to a stirring rod 43, and a plurality of stirring blades 42 are fixedly connected to the stirring rod 43. When the water in the transmission box 4 is squeezed out, edible salt is mixed in the water. In order to reduce the impact of salt in the water on the water level sensor 2, the third electromagnet 41 can be adsorbed on the rack 39 during the movement of the transmission box 4, and then the rack 39 can move with the transmission box 4. The rack 39 drives the gear 40 to rotate during the movement, and the gear 40 drives the stirring rod 43 to rotate. The stirring blades 42 stir the water near the transmission box 4 during the rotation of the stirring rod 43, and then the salt water can be quickly dispersed to other positions in the water, thereby reducing the impact of the salt water on the water level sensor 2.

[0029] The identification mechanism includes an identification box 30, a transparent sheet 31, a camera 32, and a control component for realizing the transparent sheet 31 adhering to the sludge. The identification box 30 is fixed on the housing 1. The camera 32 is arranged in the identification box 30. The camera 32 is directly facing the transparent sheet 31. The transparent sheet 31 can be made of glass material. The control component includes non-woven fabric, two control panels 34, two control blocks 35, a second spring 36, a second electromagnet 37, and a control electric push rod 38. A protective box is arranged outside the control electric push rod 38. The control electric push rod 38 The non-woven fabric sheet 33 is fixed to the outside of the identification box 30, and the two ends of the non-woven fabric sheet 33 are respectively fixedly connected to the two control boards 34, and the two control blocks 35 are respectively fixedly connected to the two control boards 34. The second spring 36 is fixedly connected to any one of the control blocks 35, and the other end is fixedly connected to the outer wall of the identification box 30. The non-woven fabric sheet 33 is close to the transparent sheet 31, and the output end of the control electric push rod 38 is fixedly connected to the second electromagnet 37, and the second electromagnet 37 is adsorbed on the control block 35 away from the second spring 36; in the initial state, the non-woven fabric sheet 33 is close to the transparent sheet 31, the non-woven fabric sheet 33 is more likely to adhere to silt in water than the transparent sheet 31, so the accuracy of judging silt can be improved. First, the electric push rod 38 is controlled to drive the second electromagnet 37 and the corresponding control block 35 to move in a direction away from the second spring 36, and the second spring 36 is stretched, and the adsorption of the second electromagnet 37 on the control block 35 is removed. Under the elastic force of the second spring 36, the non-woven fabric sheet 33 is ejected in the direction of the second spring 36, which can stir the silt near the non-woven fabric sheet 33. Its violent movement can also make the non-woven fabric sheet 33 contact with the silt in the water more violently, so that the silt can quickly adhere to the non-woven fabric sheet 33. When the second electromagnet 37 of the control electric push rod 38 is pushed to the position corresponding to the control block 35, the non-woven fabric sheet 33 is straightened and tightly attached to the transparent sheet 31. After the transparent sheet 31 contacts the non-woven fabric sheet 33, if there is silt on the non-woven fabric sheet 33, it can be coated on the transparent sheet 31, which is convenient for the staff to discover through the camera 32, and then it is necessary to start cleaning the silt outside the shell 1.

[0030] The implementation principle of a Beidou dual-channel groundwater monitoring system in the embodiment of the present application is as follows: in the initial state, the non-woven fabric sheet 33 is close to the transparent sheet 31. The non-woven fabric sheet 33 is more likely to adhere to silt in the water than the transparent sheet 31, so the accuracy of judging the silt can be improved. First, the electric push rod 38 is controlled to drive the second electromagnet 37 and the corresponding control block 35 to move in a direction away from the second spring 36. The second spring 36 is stretched, and the adsorption of the second electromagnet 37 on the control block 35 is removed. Under the elastic force of the second spring 36, the non-woven fabric sheet 33 is elastically moved in the direction of the second spring 36. The injection can not only stir the sludge near the non-woven fabric sheet 33 to make it move violently, but also make the non-woven fabric sheet 33 contact with the sludge in the water more violently, so that the sludge can quickly adhere to the non-woven fabric sheet 33. When the second electromagnet 37 of the electric push rod 38 is pushed to the position corresponding to the control block 35, the non-woven fabric sheet 33 is straightened and tightly attached to the transparent sheet 31. After the transparent sheet 31 contacts the non-woven fabric sheet 33, if there is sludge on the non-woven fabric sheet 33, it can be coated on the transparent sheet 31, which is convenient for the staff to find through the camera 32, and then it is necessary to start cleaning the sludge outside the shell 1.

[0031] When the transmission box 4 is in the cavity state, it cannot drive the ring knife 3 to move downward, or the movement speed is slow. In order to enable the transmission box 4 to smoothly drive the ring knife 3 to clean the outside of the shell 1, the first solenoid valve 5 is opened, and water continuously enters the transmission box 4 until the water sensor 6 at the top recognizes that the transmission box 4 is full of water. At this time, the first solenoid valve 5 is stopped, and the first electromagnet 27 and the ring knife 3 are released, and the ring knife 3 starts to move downward under the gravity of the transmission box 4; in order to accelerate the cleaning effect of the shell 1 and ensure that the water level sensor 2 quickly enters the working state, the second solenoid valve 10 is opened, and the edible salt in the weight-increasing box 8 enters the transmission box 4. Since the edible salt can be quickly dissolved in the water in the transmission box 4 and will not have a significant impact on the volume of the transmission box 4, the weight of the water in the transmission box 4 increases, thereby achieving the effect of further increasing the weight of the transmission box 4 without expanding the volume of the transmission box 4. As the weight of the weight-increasing box 8 increases, the downward speed of the ring knife 3 is accelerated, thereby accelerating the rapid cleaning of the silt on the outer wall of the shell 1.

[0032] When it is necessary to increase the buoyancy of the floating box 17 and the transmission box 4, the third solenoid valve 20 is opened. Since the water content required for the quicklime reaction is small, after the water reacts with the quicklime in the non-woven bag 18, the quicklime releases a large amount of heat and produces carbon dioxide. Since the transmission box 4 and the floating box 17 are coated with thermal insulation materials on the outside, the heat loss caused by heat transfer between the water is reduced. At this time, the airbag 19 overcomes the water pressure and begins to expand. As the airbag 19 expands, the buoyancy of the floating box 17 and the transmission box 4 is greatly increased. Under the elastic force of the first spring 11 and the buoyancy of the airbag 19, the ring knife 3 moves quickly to the position abutting against the trigger rod 26, and the top of the trigger rod 26 abuts against the proximity switch 28, and the first electromagnet 27 adsorbs the ring knife 3.

[0033] 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.
