Technical Field
[0001] The invention belongs to the technical field of pollutant sampling, in particular to a pollutant sampling device for water pollution control and detection. Background Art
[0002] Water pollution is the deterioration of water quality caused by harmful chemicals produced from various sources such as industrial discharge, agricultural activities, urban domestic sewage, accidental leakage, etc. These pollutants include but are not limited to acids, alkalis, heavy metals and organic solutions. Heavy metals include copper, cadmium, mercury, arsenic, and organic solvents include benzene, ethylene dichloride, ethylene glycol, etc. They can cause adverse changes in the chemical, physical, biological or radioactive properties of water bodies, affecting the use value and ecological health of water bodies.
[0003] To this end, accurate detection and assessment of pollutant content in water bodies is essential for implementing effective water pollution control measures. This requires reliable sampling devices to collect representative water samples for subsequent laboratory analysis. Accurate sampling and testing is not only related to our understanding of current water quality conditions, but also directly affects future water resource planning, pollution control strategies and ecosystem restoration plans.
[0004] The existing sampling devices are designed to collect pollutants in liquid media, mainly targeting soluble chemicals, microorganisms and other tiny particles suspended in water. However, they cannot effectively extract solid pollutants. The distribution of solid pollutants is often uneven, and traditional sampling devices are difficult to effectively capture these irregularly distributed pollutants. In addition, solid pollutants often cause blockage at the entrance of the sampling device, affecting the normal sampling process. Therefore, it is necessary to propose a pollutant sampling device for water pollution control and detection. Summary of the invention
[0005] In order to solve the problem that the above-mentioned solid pollutants are unevenly distributed and the sampling device is difficult to effectively capture these irregularly distributed solid pollutants, the purpose of the present invention is to provide a pollutant sampling device for water pollution control and detection. By adopting high-efficiency adsorption materials, it can specifically adsorb pollutants such as organic matter, heavy metal ions, microbial residues and suspended particles in water, thereby providing data support for pollution source analysis and environmental risk assessment.
[0006] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a pollutant sampling device for water pollution control detection, comprising a shell, a plurality of sampling tubes are installed in the shell, and the sampling tubes are all slidably matched with the inner wall of the shell; a threaded rod is fixedly connected in the shell, and a rotating assembly for driving the sampling tube to move vertically is provided at the connection between the threaded rod and the sampling tube;
[0007] The rotating component includes a shell, a threaded rod passes through the shell and slides with the shell, a rotating motor is fixedly connected to the inner wall of the shell, the rotating motor signal is connected to the controller, the rotating motor output shaft is coaxially fixedly connected to the first gear, the first gear is meshed with the second gear, the second gear is threadedly engaged with the threaded rod, the second gear is coaxially fixedly connected to a rotating nut, and the rotating nut is threadedly engaged with the threaded rod; the outer side of the shell is fixedly connected to the sampling barrel; a water intake component for collecting water is provided in the sampling barrel; an adsorption component for adsorbing pollutants is provided on the side of the sampling barrel away from the water intake component.
[0008] The principle of the basic scheme is: first, when sampling is required, since several sampling barrels are installed in the shell, there is a sliding fit relationship between the sampling barrel and the inner wall of the shell, so the sampling barrel is allowed to move in the vertical direction. When the rotating motor receives the controller operation instruction, its output shaft is fixedly connected to the first gear, and the first gear is meshed with the second gear, so the rotating motor can make the first gear rotate and drive the second gear to rotate. Because the second gear is coaxially fixedly connected with a rotating nut, and the rotating bolt is rotated with the threaded rod, when the first gear drives the second gear to rotate, the rotating nut can be rotated on the threaded rod, and the rotating nut can be matched with the thread of the threaded rod to achieve vertical linear motion of the rotating nut on the threaded rod. Since the outer side of the rotating nut is sleeved with a shell, and the shell is fixedly connected to the sampling barrel, the vertical linear motion of the sampling barrel can be achieved through the controller. When the sampling barrel reaches the designated sampling location, the water collection component located in the sampling barrel is responsible for collecting water samples when the sampling barrel descends to the designated water depth in the shell to ensure that the water sample is accurately collected. And the solid pollutants in the water sample are collected by the adsorption component provided inside the sampling barrel.
[0009] The beneficial effects of the basic scheme are: 1. The device is equipped with multiple sampling barrels, each of which can be operated independently, which means that at the same time, multiple sampling barrels can collect water samples at different locations at the same time, greatly improving the sampling efficiency. The linkage mechanism between the sampling barrel, the threaded rod and the rotating assembly enables the sampling barrel to accurately adjust its position in the vertical direction, thereby realizing the collection of samples at different depths in the same vertical direction. Combined with multi-point sampling and depth adjustment functions, this device can provide a more comprehensive water quality assessment, thereby improving the accuracy and representativeness of sampling.
[0010] 2. The adsorption component of this device uses high-efficiency adsorption materials, which can specifically adsorb pollutants such as organic matter, heavy metal ions, microbial residues and suspended particles in the water, and conduct subsequent analysis on the collected samples to further ensure the accuracy and reliability of water pollution detection. According to different pollution types and detection requirements, the adsorption component can use adsorption materials or combinations with different characteristics to achieve simultaneous adsorption of multiple pollutants, enhance the versatility and flexibility of the sampling device, and is suitable for monitoring different water bodies and pollution conditions.
[0011] 3. This device collects water samples and solid samples separately. This mechanism reduces the mixing of water samples and solid pollutants, reduces the interference of solid matter on water quality analysis, and enables the laboratory to more accurately measure the concentration of dissolved pollutants in the water. By collecting and analyzing water samples and solid samples at the same time, more comprehensive pollution status information can be obtained, including the accumulation of pollutants in suspended matter and sediments, as well as the pollution indicators of the water itself, providing richer data support for pollution source analysis and environmental risk assessment.
[0012] Furthermore, the water extraction component includes a push plate, which is located inside the sampling barrel; a rubber piston is fixedly connected to one end of the push plate, and the rubber piston slides with the inner wall of the sampling barrel; a power component for driving the push plate to move horizontally is provided on the side of the sampling barrel away from the shell, and openings for the power component to move are opened on the side of the shell and the sampling barrel away from the push plate, and a spiral check valve is installed at the opening.
[0013] The beneficial effect of the basic scheme is that when the sampling tube needs to collect water, the power assembly is activated to drive the push plate to move inside the sampling tube. The rubber piston slides along the inner wall of the sampling tube under the pull of the push plate to form a negative pressure area, and the external water flows into the sampling tube through the spiral check valve. When the water sample in the sampling tube reaches the predetermined volume, the special design of the spiral check valve prevents the water sample from flowing back, which can effectively prevent the leakage of the sample or the mixing of external impurities, ensure the purity and integrity of the sample, and reduce the error in the subsequent analysis process.
[0014] Furthermore, the power assembly includes a power motor, and the controller is used to control the operation of the power motor. The power motor is fixedly connected to the outside of the sampling tube; the power motor output shaft is coaxially fixedly connected with a power gear, and a power rack is meshed at the bottom of the power gear. The push plate extends from the inside of the sampling tube to the outside of the sampling tube, and the power rack is fixedly connected to the side of the push plate away from the threaded rod.
[0015] The beneficial effects of the basic scheme are: the power motor starts after receiving the sampling command from the controller. Because the output shaft of the power motor is fixedly connected to the power gear, and the power gear is meshed with the power rack, the rotation of the power motor will cause the power gear to rotate. When the power gear rotates, it forms a transmission system with the power rack, driving the power rack to move in a straight line, and then driving the push plate and the rubber piston to reciprocate in the sampling tube. The push plate and the rubber piston move axially along the sampling tube, compressing the air in the sampling tube to form negative pressure, and the external water is sucked into the sampling tube through the spiral check valve. Through the integration of power components, the automatic control of the sampling process is realized, the tediousness of manual operation and possible errors are reduced, and the sampling efficiency and safety are improved.
[0016] Furthermore, the adsorption component includes a float camera, the controller is used to receive the float camera signal, an adsorption layer is fixedly connected to the outside of the float camera, and the adsorption layer is selected from one or more of activated carbon, molecular sieve, clay mineral, synthetic polymer and magnetic adsorbent;
[0017] The float camera is located in the sampling tube away from the rubber piston. The float camera and the push plate are slidably matched. The push plate is provided with an ejection component for driving the float camera to move horizontally. The shell and the sampling tube away from the water collection component are provided with interfaces for the ejection component to move.
[0018] The beneficial effects of the basic scheme are as follows: The main function of the float camera is to capture images of the inside of the water body to monitor the physical state of the water body and the distribution of pollutants. The controller receives signals from the float camera, including image data and the distribution of pollutants, and analyzes the water body conditions, automatically controlling the start and stop of the adsorption component according to the water body conditions. The sampling frequency of the sampling device is automatically adjusted according to the preset pollution threshold. When the environmental pollution level increases, the sampling frequency is increased to obtain more accurate sampling data.
[0019] The adsorption layer uses one or more highly efficient adsorption materials, which can specifically adsorb specific pollutants in the water, such as heavy metal ions, organic compounds and microorganisms, thus improving the efficiency and accuracy of water quality testing. It can be flexibly configured according to different water bodies and pollutant types, enhancing the ability of the adsorption component to adapt to complex water environments. It also provides data support for subsequent water quality analysis and pollution control.
[0020] Furthermore, the ejection assembly includes a connecting rod and a spring, a first wedge block is fixedly connected to the side of the push plate away from the float camera, the connecting rod passes through the first wedge block and slides with the first wedge block; the spring is sleeved on the outside of the connecting rod, one end of the spring is fixedly connected to the first wedge block, and the end of the spring away from the first wedge block is fixedly connected to the second wedge block, the second wedge block slides with the push plate, the height of the second wedge block is smaller than the first wedge block, and the two sides of the second wedge block are respectively fixedly connected to the connecting rod and the float camera; a "7"-shaped vertical axis is fixedly connected to the side of the sampling tube away from the power motor, and a toggle rod is rotatably engaged with the horizontal end of the vertical axis, the toggle rod is arranged in an inclined surface away from the vertical axis, and a third wedge is fixedly connected to the bottom side of one end of the toggle rod, the toggle rod inclined surface and the third wedge block are both located above the first wedge block and the second wedge block, and the toggle rod inclined surface slides with the inclined surface of the first wedge block.
[0021] The beneficial effect of the basic scheme is that when the push plate moves into the sampling tube, because the push plate is fixedly connected to the first wedge block, the first wedge block is slidably matched with the connecting rod, and a spring is sleeved on the outer side of the connecting rod, and the two ends of the spring are respectively fixedly connected to the first wedge block and the second wedge block, so when the push plate moves, the first wedge block and the second wedge block can move inward together. Since the inclined surface of the toggle rod and the third wedge block are both located above the first wedge block and the second wedge block, when the second wedge block moves to contact the third wedge block, the second wedge block will be blocked by the third wedge block, and the first wedge block can also move inward with the push plate, and at this time, the spring fixedly connected to the first wedge block is compressed to store energy. And because the height of the first wedge block is greater than that of the second wedge block, the inclined surface of the toggle rod slides with the inclined surface of the first wedge block. Therefore, when the push plate moves to the point where the first wedge block contacts the inclined surface of the toggle rod, the inclined surface of the toggle rod will be lifted up by the inclined surface of the first wedge block and slide upward, thereby lifting a certain distance, so that the second wedge block is separated from the third wedge block. At this time, the power motor stops rotating, and the second wedge block will be ejected a distance toward the interface between the sampling tube and the shell by the elastic force of the spring.
[0022] At this time, the float camera fixedly connected to the second wedge will be ejected together. When ejected, some solid pollutants in the water can be adsorbed and collected by the adsorption layer on the surface of the float camera. This linkage trigger mechanism does not require additional external control and simplifies the operation process. The kinetic energy conversion using the elastic potential energy of the spring reduces energy consumption and the cost of equipment operation, while also reducing the complexity and maintenance difficulty of the equipment.
[0023] Furthermore, a submarine is fixedly connected to the top of the shell, and the controller is used to control the operation of the submarine.
[0024] The beneficial effect of the basic scheme is that through the design of the submarine, the sampling device can be used to take samples at any position in the water. The submarine fills the ballast tank with water, which increases the total weight of the submarine. Once the weight of the submarine is greater than the weight of the water it displaces, the submarine begins to dive. When the submarine needs to surface, the water in the ballast tank is squeezed out by using high-pressure air, thereby reducing the total weight of the submarine. When the weight of the submarine is less than the weight of the water it displaces, the submarine begins to surface. The deep diving capability of the submarine means that sampling is no longer limited to the surface or shallow water areas, and can cover a wider range of water depths and obtain more comprehensive water quality data.
[0025] Furthermore, the spiral check valve is connected to the interior of the sampling cylinder. The spiral check valve includes a plurality of U-shaped connecting pipes. The connecting pipes are all connected to each other, and the openings of the connecting pipes are all toward the input end of the sampling cylinder.
[0026] The beneficial effect of the basic scheme is that when the sampling tube collects water samples, because the spiral check valve is interconnected by a number of U-shaped connecting pipes, and the opening of the U-shaped connecting pipe faces the input end of the sampling tube, when the liquid flows through from the input end, it can pass quickly and be directed into the sampling tube; on the contrary, when the liquid flows back from the input of the sampling tube, it will be blocked by the bend of the U-shaped connecting pipe. When the liquid is blocked by the bend many times, the kinetic energy of the liquid gradually decreases, thereby reducing the situation of liquid backflow in the spiral check valve. This feature of no moving parts reduces the possibility of mechanical wear and failure, improves the reliability and service life of the sampling device, and reduces maintenance costs.
[0027] Furthermore, a GPS locator is fixedly connected inside the submarine, and the controller is used to receive signals from the GPS locator.
[0028] The basic solution has the following benefits: the GPS locator can provide accurate geographic coordinates to ensure accurate records of each sampling location, which is convenient for subsequent data analysis and pollutant tracking. Integration with the controller increases the convenience of remote control, and the location and status of the sampling device can be transmitted to the user terminal in real time, which is convenient for scientific researchers and environmental managers to monitor the sampling process and adjust the sampling plan in a timely manner.
[0029] Furthermore, a depth sensor is fixedly connected inside the housing, and the controller is used to receive a signal from the depth sensor.
[0030] The benefits of the basic solution are: the depth sensor determines the specific location of the device underwater by transmitting and receiving sound wave information, ensuring that the sampling device can accurately reach the preset water layer depth and improve the efficiency of the sampling process. Accurate depth information combined with water quality data improves the accuracy and reliability of data analysis, helping to more accurately identify pollution sources and assess pollution levels.
[0031] Furthermore, limit blocks are installed between adjacent sampling tubes, and the limit blocks are fixedly connected to the inner wall of the shell.
[0032] The basic scheme has the following beneficial effects: each sampling tube is ensured to stop at a specified position by means of a stop block fixed in the housing, thereby achieving precise control of the sampling depth. It can avoid collisions during the vertical movement of the sampling tube, protect the sampling tube from physical damage, and extend the service life of the device. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0039] The following is further described in detail through specific implementation methods:
[0040] Embodiment 1, basically as attached Figure 1-Figure 5 As shown: a pollutant sampling device for water pollution control detection, including a shell 1, a plurality of sampling tubes 2 are installed in the shell 1, and the sampling tubes 2 are slidably matched with the inner wall of the shell 1; a threaded rod 3 is fixedly connected with bolts in the shell 1, and a rotating component for driving the sampling tube 2 to move vertically is provided on the outside of the sampling tube 2 near the threaded rod 3.
[0041] The rotating assembly includes a shell 8, a threaded rod 3 passes through the shell 8 and is slidably matched with the shell 8, a rotating motor 4 is bolted and fixedly connected to the inner wall of the shell 8, the model of the rotating motor 4 is preferably HG-KNS, the signal of the rotating motor 4 is connected to a controller, the model of the controller is preferably S7-1500, the output shaft of the rotating motor 4 is coaxially fixedly welded with a first gear 5, the first gear 5 is meshed with a second gear 6, the second gear 6 is threadedly matched on the threaded rod 3, the second gear 6 is coaxially fixedly welded with a rotating nut 7, and the rotating nut 7 is threadedly matched with the threaded rod 3; the outer side of the shell 8 is bolted and fixedly connected to the sampling tube 2; a water intake assembly for collecting water bodies is provided in the sampling tube 2.
[0042] The water intake assembly includes a push plate 9, which is located inside the sampling tube 2; a rubber piston 10 is fixedly bonded to one end of the push plate 9, and the rubber piston 10 slides with the inner wall of the sampling tube 2; a power assembly for driving the push plate 9 to move horizontally is provided on the side of the sampling tube 2 away from the shell 8; an opening for the power assembly to move is provided on the side of the outer shell 1 and the sampling tube 2 away from the push plate 9, and a spiral check valve 11 is installed at the opening.
[0043] The power assembly includes a power motor 12, and the model of the power motor 12 is preferably NEMA24. The controller is used to control the operation of the power motor 12, and the power motor 12 is bolted and fixedly connected to the outside of the sampling tube 2; the output shaft of the power motor 12 is coaxially fixedly welded with a power gear 13, and the bottom of the power gear 13 is meshed with a power rack 14. The push plate 9 extends from the inside of the sampling tube 2 to the outside of the sampling tube 2, and the power rack 14 is bolted and fixedly connected to the side of the push plate 9 away from the threaded rod 3.
[0044] When the sampling tube 2 needs to collect water, the power motor 12 starts after receiving the sampling command from the controller. Because the power gear 13 is coaxially fixed and welded to the output shaft of the power motor 12, and the power gear 13 is meshed with the power rack 14, the rotation of the power motor 12 will cause the power gear 13 to rotate. When the power gear 13 rotates, it forms a transmission system with the power rack 14, driving the power rack 14 to move in a straight line, thereby driving the push plate 9 and the rubber piston 10 to reciprocate in the sampling tube 2. The push plate 9 and the rubber piston 10 move axially along the sampling tube 2, compressing the air in the sampling tube 2 to form a negative pressure, and the external water is sucked into the sampling tube 2 through the spiral check valve 11. Through the integration of power components, the automatic control of the sampling process is realized, the tediousness of manual operation and possible errors are reduced, and the sampling efficiency and safety are improved.
[0045] The external water flows into the sampling tube 2 through the spiral check valve 11. When the water sample in the sampling tube 2 reaches a predetermined volume, the special design of the spiral check valve 11 prevents the water sample from flowing back, which can effectively prevent the sample from leaking or mixing with external impurities, ensure the purity and integrity of the sample, and reduce errors in the subsequent analysis process.
[0046] An adsorption component for adsorbing pollutants is provided on the side of the sampling tube 2 away from the water intake component. The adsorption component includes a float camera 15. The model of the float camera 15 is preferably Samsung SNB-6010R. The controller is used to receive the signal of the float camera 15. An adsorption layer is fixedly bonded to the outside of the float camera 15. The adsorption layer is selected from one or more of activated carbon, molecular sieves, clay minerals, synthetic polymers and magnetic adsorbents.
[0047] The adsorption layer uses one or more highly efficient adsorption materials, which can specifically adsorb specific pollutants in the water, such as heavy metal ions, organic compounds and microorganisms, thus improving the efficiency and accuracy of water quality testing. It can be flexibly configured according to different water bodies and pollutant types, enhancing the ability of the adsorption component to adapt to complex water environments. It also provides data support for subsequent water quality analysis and pollution control.
[0048] The float camera 15 is located in the sampling tube 2 on the side away from the rubber piston 10. The float camera 15 slides with the push plate 9. The push plate 9 is provided with an ejection component for driving the float camera 15 to move horizontally. The housing 1 and the sampling tube 2 on the side away from the water intake component are provided with interfaces for the ejection component to move.
[0049] The ejection assembly includes a connecting rod 16 and a spring 17. A first wedge 18 is bolted and fixedly connected to the push plate 9 on the side away from the floating ball camera 15. The connecting rod 16 passes through the first wedge 18 and slides with the first wedge 18. The spring 17 is sleeved on the outside of the connecting rod 16. One end of the spring 17 is bolted and fixedly connected to the first wedge 18. The end of the spring 17 away from the first wedge 18 is bolted and fixedly connected to the second wedge 19. The second wedge 19 slides with the push plate 9. The height of the second wedge 19 is less than that of the first wedge 18. The second wedge 19 is divided into two parts on both sides. It is fixedly connected with the connecting rod 16 and the float camera 15 by bolts; a vertical axis in the shape of "7" is bolted fixedly connected to the side of the sampling tube 2 away from the power motor 12, and a toggle rod 21 is rotatably matched at the horizontal end of the vertical axis. The toggle rod 21 is arranged in an inclined surface at one end away from the vertical axis, and a third wedge 20 is bolted fixedly connected to the bottom side of one end of the inclined surface on the toggle rod 21. The inclined surface of the toggle rod 21 and the third wedge 20 are both located above the first wedge 18 and the second wedge 19, and the inclined surface of the toggle rod 21 slides with the inclined surface of the first wedge 18.
[0050] When the push plate 9 moves into the sampling tube 2, because the push plate 9 is bolted and fixedly connected with the first wedge 18, the first wedge 18 is slidably matched with the connecting rod 16, and the outer side of the connecting rod 16 is sleeved with a spring 17, and the two ends of the spring 17 are bolted and fixedly connected with the first wedge 18 and the second wedge 19 respectively; therefore, when the push plate 9 moves, the first wedge 18 and the second wedge 19 can move inward together. Since the inclined surface of the toggle rod 21 and the third wedge 20 are both located above the first wedge 18 and the second wedge 19, when the second wedge 19 moves to contact with the third wedge 20, the second wedge 19 will be blocked by the third wedge 20, and the first wedge 18 can also move inward with the push plate 9, at which time the spring 17 bolted and fixedly connected to the first wedge 18 is compressed and stores energy. And because the height of the first wedge block 18 is greater than that of the second wedge block 19, the inclined surface of the toggle rod 21 slides with the inclined surface of the first wedge block 18. Therefore, when the push plate 9 moves to the point where the first wedge block 18 contacts the inclined surface of the toggle rod 21, the inclined surface of the toggle rod 21 will be lifted up by the inclined surface of the first wedge block 18 and slide upward, thereby lifting a certain distance, so that the second wedge block 19 is separated from the third wedge block 20. At this time, the power motor 12 stops rotating, and the second wedge block 19 will be ejected a certain distance toward the interface of the sampling tube 2 by the elastic force of the spring 17, thereby ejected to the outside of the outer shell 1.
[0051] At this time, the float camera 15 connected by the bolts of the second wedge 19 will be ejected together. When ejected, some solid pollutants in the water can be adsorbed and collected by the adsorption layer fixed and bonded on the surface of the float camera 15. This linkage trigger mechanism does not require additional external control, which simplifies the operation process. The elastic potential energy of the spring 17 is used to convert kinetic energy, which reduces energy consumption, reduces the cost of equipment operation, and also reduces the complexity and maintenance difficulty of the equipment.
[0052] The main function of the float camera 15 is to capture images of the interior of the water body to monitor the physical state of the water body and the distribution of pollutants. The controller receives signals from the float camera 15, including image data and the distribution of pollutants, and analyzes the water body conditions, and automatically controls the start and stop of the adsorption component according to the water body conditions. The sampling frequency of the sampling device is automatically adjusted according to the preset pollution threshold. When the environmental pollution level increases, the sampling frequency is increased to obtain more accurate sampling data.
[0053] The specific implementation process is as follows: First, when sampling is required, since a number of sampling tubes 2 are installed in the housing 1, there is a sliding fit relationship between the sampling tube 2 and the inner wall of the housing 1, so the sampling tube 2 is allowed to move in the vertical direction. When the rotating motor 4 receives the controller operation instruction, its output shaft is fixedly welded to the first gear 5, and the first gear 5 is meshed with the second gear 6, so the rotating motor 4 can make the first gear 5 rotate and drive the second gear 6 to rotate. Because the second gear 6 is coaxially fixedly welded with a rotating nut 7, and the rotating bolt is rotated with the threaded rod 3, when the first gear 5 drives the second gear 6 to rotate, the rotating nut 7 can rotate on the threaded rod 3, and the rotating nut 7 is threaded with the threaded rod 3, so that the rotating nut 7 can be vertically linearly moved on the threaded rod 3. Since the outer side of the rotating nut 7 is sleeved with a shell 8, and the shell 8 is fixedly connected with the sampling tube 2 by bolts, the vertical linear movement of the sampling tube 2 can be realized through the controller. When the sampling tube 2 reaches the designated sampling location, the water collection component located in the sampling tube 2 is responsible for collecting water samples when the sampling tube 2 descends to the designated water depth in the housing 1, ensuring that the water samples are accurately collected. The adsorption component inside the sampling tube 2 is also provided to collect solid pollutants in the water samples.
[0054] This device is equipped with multiple sampling tubes 2, each of which can be operated independently, which means that at the same time, multiple sampling tubes 2 can collect water samples at different locations at the same time, greatly improving the sampling efficiency. The linkage mechanism between the sampling tube 2, the threaded rod 3 and the rotating assembly enables the sampling tube 2 to accurately adjust its position in the vertical direction, thereby realizing the collection of samples with different depths in the same vertical direction. Combined with the multi-point sampling and depth adjustment functions, this device can provide a more comprehensive water quality assessment, thereby improving the accuracy and representativeness of sampling. By collecting water samples and solid samples separately, this mechanism reduces the mixing of water samples and solid pollutants, reduces the interference of solid matter on water quality analysis, and enables the laboratory to more accurately measure the concentration of soluble pollutants in the water. By collecting and analyzing water samples and solid samples at the same time, more comprehensive pollution status information can be obtained, including suspended matter, accumulation of pollutants in sediments, and pollution indicators of the water body itself, providing richer data support for pollution source analysis and environmental risk assessment.
[0055] Embodiment 2:
[0056] The difference from the above embodiment is that the top of the housing 1 is bolted and fixedly connected with a submarine 22, and the controller is used to control the operation of the submarine 22. The inside of the housing 1 is bolted and fixedly connected with a depth sensor, the model of the depth sensor is preferably DT800-Airmar, and the controller is used to receive the depth sensor signal.
[0057] The specific implementation process is as follows: First, when the device is sampling, the design of the submarine 22 can realize sampling at any position in the water. The submarine 22 fills the ballast tank with water, which increases the total weight of the submarine 22. Once the weight of the submarine 22 is greater than the weight of the water it displaces, the submarine 22 begins to dive. When the submarine 22 needs to surface, the water in the ballast tank is squeezed out by using high-pressure air, thereby reducing the total weight of the submarine 22. When the weight of the submarine 22 is less than the weight of the water it displaces, the submarine 22 begins to surface. The deep diving capability of the submarine 22 means that sampling is no longer limited to the water surface or shallow water areas, and can cover a wider range of water depths and obtain more comprehensive water quality data.
[0058] When the device is operating underwater, the depth sensor determines the specific location of the device underwater by transmitting and receiving sound wave information, ensuring that the sampling device can accurately reach the preset water layer depth and improve the efficiency of the sampling process. Accurate depth information combined with water quality data improves the accuracy and reliability of data analysis, helping to more accurately identify pollution sources and assess the extent of pollution.
[0059] Embodiment 3:
[0060] The difference from the above embodiment is that the spiral check valve 11 is connected to the inside of the sampling tube 2 , and the spiral check valve 11 includes a plurality of U-shaped connecting pipes, which are all connected to each other, and the openings of the connecting pipes are all toward the input end of the sampling tube 2 .
[0061] The specific implementation process is as follows: when the sampling tube 2 collects water samples, because the spiral check valve 11 is interconnected by a plurality of U-shaped connecting pipes, and the opening of the U-shaped connecting pipe faces the input end of the sampling tube 2, when the liquid flows through from the input end, it can pass quickly and be directed into the sampling tube 2; on the contrary, when the liquid flows back from the input of the sampling tube 2, it will be blocked by the bend of the U-shaped connecting pipe. When the liquid is blocked by the bend for many times, the kinetic energy of the liquid gradually decreases, thereby reducing the situation of liquid backflow in the spiral check valve 11. This feature of no moving parts reduces the possibility of mechanical wear and failure, improves the reliability and service life of the sampling device, and reduces maintenance costs.
[0062] Embodiment 4:
[0063] The difference from the above embodiment is that a GPS locator is fixedly connected with bolts inside the submarine 22, and the GPS locator model is preferably Spytec STI GL300MA, and the controller is used to receive GPS locator signals.
[0064] The specific implementation process is as follows: When the submarine 22 dives, the GPS locator can provide accurate geographic location coordinates to ensure accurate recording of each sampling location, which is convenient for subsequent data analysis and pollutant tracking. By integrating with the controller, the convenience of remote control is increased, and the location and status of the sampling device can be transmitted to the user terminal in real time, which is convenient for scientific researchers and environmental managers to monitor the sampling process and adjust the sampling plan in a timely manner.
[0065] Embodiment 5:
[0066] The difference from the above embodiment is that a limiting block 23 is installed between adjacent sampling tubes 2 , and the limiting block 23 is fixedly connected to the inner wall of the housing 1 with bolts.
[0067] The specific implementation process is as follows: when the sampling tube 2 moves vertically in the housing 1, the limit block 23 fixedly connected by bolts in the housing 1 ensures that each sampling tube 2 stops at a specified position, thereby achieving precise control of the sampling depth. It can avoid collisions during the vertical movement of the sampling tube 2, protect the sampling tube 2 from physical damage, and extend the service life of the device.
