Description

Technical Field

[0001] The present invention generally relates to the technical field of water source sampling, and specifically provides a storage-type water source sampling device for environmental detection. Background Art

[0002] In many fields such as environmental monitoring and scientific research experiments, water source sampling is a crucial task, and the sample data obtained is of great significance for understanding the water quality status and studying the water ecological environment.

[0003] Currently, the existing water source sampling devices mainly rely on manual water sampling. In actual operation, in many cases, it is necessary to conduct multiple samplings at different depths and different time periods in the water area. For example, when studying the vertical stratification structure of the water body, water samples at different depths need to be collected; when analyzing the variation law of water quality over time, sampling work needs to be carried out at different time periods.

[0004] However, the existing water source sampling devices are difficult to meet such requirements. On the one hand, they do not have the function of automatically sampling at different depths. To obtain water samples at different depths, operators can only manually adjust the sampling position, which is not only cumbersome to operate but also difficult to guarantee the accuracy. On the other hand, for multiple samplings at different time periods, the existing devices cannot achieve automatic timed sampling and must rely on manual multiple round trips between the laboratory and the water source to be sampled. This not only consumes a large amount of manpower, material resources and time, but also may affect the accuracy and scientific nature of the sample data due to inaccurate sampling intervals and other factors, seriously restricting the efficiency and quality of the water source sampling work.

[0005] Therefore, there is an urgent need to develop a new type of water source sampling device that can automatically sample at different depths and different time periods. Summary of the Invention

[0017] The embodiments of the present invention have the following advantages.

[0018] When using this sampling device for continuous water quality sampling, the sampling device can be thrown into the water body by a drone. After the sampling device finishes sampling, the drone can identify the photovoltaic buoy assembly and salvage the sampling device.

[0019] After the sampling device is placed in the water body, the first wire winding assembly pays out the wire so that the anchor body falls to the bottom of the water, preventing the sampling device from detaching from the area to be sampled due to the too fast water flow rate. Since each sampling bottle is filled with air, the buoyancy of the sampling device is at its maximum at this time, denoted as the first sampling depth. The sampling valve assembly is activated, and the external water body and one of the sampling bottles are connected through a pipeline, allowing one of the multiple sampling bottles to intake water. During the water intake process of the sampling bottle, air is continuously exhausted upwards, causing the buoyancy of the sampling device to decrease. The first box body and the second box body continuously sink, and the second wire winding assembly pays out the wire so that the photovoltaic buoy assembly floats on the water surface. During the sinking process, the first wire winding assembly starts to take in the wire, reducing the distance between the anchor body and the first box body, preventing the first box body from being driven by the water flow to move a long distance due to the excessive payout of the first wire winding assembly. When the air in the first sampling bottle is completely exhausted, the sampling valve assembly closes, and the first box body and the second box body sink to the second sampling depth. After an interval of time, the sampling valve assembly is opened again, and the second sampling bottle is connected to the external water body. The second sampling bottle starts to exhaust air and intake water. At this time, the first wire winding assembly and the second wire winding assembly repeat the above actions. After the buoyancy of the sampling device decreases, the first box body and the second box body continue to sink slowly. When the gas in the second sampling bottle is completely exhausted, the first box body and the second box body sink to the third sampling depth. Repeating the above actions can sample the water in the water area at different depths through each sampling bottle in turn, achieving the purpose of sampling the water in the water area at different depths. At the same time, when multiple samplings are required at the same depth, the second wire winding assembly and the first wire winding assembly can also pay out and take in the wire, and use the photovoltaic buoy assembly to provide buoyancy for the first box body and the second box body, enabling the sampling bottle to be suspended at a specified depth for multiple samplings at different time intervals;

[0020] Multiple sampling bottles can intake water independently and can automatically sample at different depths according to the buoyancy change. This enables the device to obtain water samples at different depths of the water body. The water at different depths may vary in aspects such as temperature, dissolved oxygen, microbial community, and chemical substance concentration. Stratified sampling helps to comprehensively understand the vertical structure and water quality distribution characteristics of the water body, which is of great significance for studying the water ecosystem, evaluating pollution diffusion and migration, etc.;

[0021] At the same time, the automatic interval sampling is realized by using the buoyancy change after the sampling bottle is collected, without frequent manual operation, which not only saves labor costs but also ensures the accuracy and consistency of the sampling time interval;

[0022] In some projects that require long-term continuous monitoring, such as studying the seasonal changes of water bodies, the impact of tides on water quality, etc., this automatic interval sampling function can provide more scientific and accurate data. Suspended sampling can be carried out using a photovoltaic buoy assembly at the same depth and can be sampled at different time periods. This helps to study the changes in water quality at the same depth over time, such as the dynamic changes in water quality at different times of the day and under different weather conditions. At the same time, multiple samplings can increase the number and representativeness of samples and improve the reliability of data analysis. The buoy suspended sampling method enables the device to be used in different water environments, such as lakes, rivers, oceans, etc. Regardless of the depth, flow rate, and topography of the water body, as long as the appropriate buoy is placed, sampling can be achieved, with strong adaptability and flexibility.

Detailed implementation manners

[0039] In order to make the objectives, solutions, and advantages of the technical solutions of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the specific embodiments of the present invention. Unless otherwise specified, the terms used herein have the ordinary meanings in the art. The same reference numerals in the drawings represent the same components.

[0040] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0041] As described above, in the use of traditional water source sampling equipment, due to the inability of existing sampling equipment to achieve continuous multiple samplings, the sampling efficiency is low.

[0042] To at least partially solve one or more of the above problems and other potential problems, exemplary embodiments of the present invention provide a storage-type water source sampling device for environmental detection. Please refer to Figures 1 - 11 , the water source sampling device includes: a plurality of sampling bottles 1; a first box body 2, with each sampling bottle 1 arranged in an array within the first box body 2; an anchor body 3, provided at the lower part of the first box body 2; a first wire winding assembly 4, provided between the anchor body 3 and the first box body 2; a second box body 5, provided at the upper end of the first box body 2; a sampling valve assembly 8, provided within the second box body 5, and the sampling valve assembly 8 is connected to each sampling bottle 1 through a pipe; a photovoltaic buoy assembly 6, floating on the water surface; a second wire winding assembly 7, provided between the photovoltaic buoy assembly 6 and the second box body 5.

[0043] In the above embodiment, when using this sampling device for continuous water quality sampling, the sampling device can be thrown into the water body by a drone. After the sampling device finishes sampling, the drone can identify the photovoltaic buoy assembly 6 and salvage the sampling device.

[0044] After the sampling device is placed in the water body, the first wire winding assembly 4 pays out the wire so that the anchor body 3 falls to the bottom of the water, preventing the sampling device from detaching from the area to be sampled due to the excessive water flow velocity. Since each sampling bottle 1 is filled with air, the buoyancy of the sampling device is at its maximum at this time, denoted as the first sampling depth. The sampling valve assembly 8 is activated, and the external water body and one of the sampling bottles 1 are connected through a pipeline, causing one of the multiple sampling bottles 1 to fill with water. During the process of the sampling bottle 1 filling with water, it continuously exhausts air upwards, causing the buoyancy of the sampling device to decrease. The first box body 2 and the second box body 5 continuously sink, and the second wire winding assembly 7 pays out the wire so that the photovoltaic buoy assembly 6 floats on the water surface. During the sinking process, the first wire winding assembly 4 starts to take in the wire, reducing the distance between the anchor body 3 and the first box body 2, preventing the first box body 2 from being driven to move a long distance by the water flow due to the excessive payout of the first wire winding assembly 4. When all the air in the first sampling bottle 1 is exhausted, the sampling valve assembly 8 closes, and the first box body 2 and the second box body 5 sink to the second sampling depth. After an interval of time, the sampling valve assembly 8 is opened again, and the second sampling bottle 1 is connected to the external water body. The second sampling bottle 1 starts to exhaust air and fill with water. At this time, the first wire winding assembly 4 and the second wire winding assembly 7 repeat the above actions. After the buoyancy of the sampling device decreases, the first box body 2 and the second box body 5 continue to slowly sink. When all the gas in the second sampling bottle 1 is exhausted, the first box body 2 and the second box body 5 sink to the third sampling depth. Repeating the above actions can sample water in the water area at different depths through each sampling bottle 1 in turn, achieving the purpose of sampling water in the water area at different depths. At the same time, when multiple samplings are required at the same depth, the second wire winding assembly 7 and the first wire winding assembly 4 can also take in and pay out the wire, and the photovoltaic buoy assembly 6 provides buoyancy for the first box body 2 and the second box body 5, enabling the sampling bottle 1 to be suspended at a specified depth for multiple samplings at different time intervals;

[0045] Multiple sampling bottles 1 can independently fill with water and can automatically sample at different depths according to the change in buoyancy. This enables the device to obtain water samples at different depths of the water body. Water at different depths may vary in terms of temperature, dissolved oxygen, microbial community, chemical substance concentration, etc. Stratified sampling helps to comprehensively understand the vertical structure and water quality distribution characteristics of the water body, which is of great significance for studying the water body ecosystem, evaluating pollution diffusion and migration, etc.;

[0046] At the same time, the automatic interval sampling is achieved by utilizing the change in buoyancy after the sampling bottle 1 is collected. There is no need for frequent manual operation, which not only saves labor costs but also ensures the accuracy and consistency of the sampling time interval;

[0047] In some projects that require long-term continuous monitoring, such as studying the seasonal changes of water bodies, the impact of tides on water quality, etc., this automatic interval sampling function can provide more scientific and accurate data. Suspended sampling can be carried out at the same depth using the photovoltaic buoy assembly 6, and sampling can be carried out at different time periods, which helps to study the changes in water quality at the same depth of the water body over time, such as the dynamic changes in water quality at different times of the day and under different weather conditions. At the same time, multiple samplings can increase the number and representativeness of samples, improve the reliability of data analysis. The buoy suspended sampling method enables the device to be used in different water environments, such as lakes, rivers, oceans, etc. Regardless of the depth, flow rate, and terrain of the water body, as long as the appropriate buoy is placed, sampling can be achieved, with strong adaptability and flexibility.

[0048] Please refer to Figures 1 - 11 , in some embodiments, the sampling bottle 1 includes: a bottle body 11, the bottle body 11 is a cuboid structure; a bottle cap 12, provided on the lower end surface of the bottle body 11 and threadedly connected to the bottle mouth of the bottle body 11; a quick-connect valve 13, provided on the upper end surface of the bottle body 11; a water inlet pipe 14, one end of which is detachably connected to the quick-connect valve 13 and the other end is connected to the sampling valve assembly 8; wherein each bottle body 11 is arranged in a rectangular array in the first box body 2.

[0049] In the above embodiments, the bottle body 11 of each sampling bottle 1 is configured as a cuboid structure. When the cuboid-structured bottle bodies 11 are arranged in the first box body 2, they are more stable compared to cylindrical barrel bodies, and the fit between the sampling bottles 1 is higher, and it is not easy to collide and twist in the box body, thus improving the problem that the sampling bottle 1 is prone to falling off from the quick-connect valve 13. The sampling valve assembly 8 is located above the bottle body 11, and one end of the water inlet pipe 14 of each bottle body 11 away from the bottle body 11 is connected to the sampling valve assembly 8, making it easier for the sampling valve assembly 8 to control the sampling work of each bottle body 11. There is no need to install an electromagnetic valve on each bottle body 11, thereby reducing costs while improving the reliability of the device and avoiding the problem that some bottle bodies 11 cannot be sampled normally due to electromagnetic valve failures. When the sampling work is completed and the sampling equipment is salvaged, place the first box body 2 and the second box body 5 on the laboratory table, with the end of each bottle body 11 with the bottle cap 12 facing down. After taking out the sampling valve assembly 8 in the second box body 5, the upper parts of each bottle body 11 are exposed. Remove the water inlet pipe 14 from the quick-connect valve 13 and move the bottle body 11 in the vertical direction. When conducting experiments on the samples in the bottle body 11, only need to block the quick-connect valve 13 with a finger and unscrew the bottle cap 12. After placing the bottle body 11 above the measuring cup, remove the finger from the quick-connect valve 13. At this time, the water in the bottle body 11 slowly flows into the measuring cup from the bottle mouth, which can not only avoid contamination of the samples in each bottle body 11, but also improve the experimental efficiency.

[0050] Please refer to Figures 1 - 11In some embodiments, the first box body 2 includes: an inner shell 21, each bottle body 11 is arranged in the inner shell 21; an outer shell 22, which is sleeved on the circumferential outer wall of the inner shell 21, and the inner wall of the outer shell 22 is spaced apart from the outer wall of the inner shell 21; the top of the inner shell 21 is connected to the bottom end of the second box body 5; the first box body 2 also includes: a rectangular mounting ring 23, the outer wall of which is connected to the inner wall of the inner shell 21; a heat dissipation component 24, which is arranged between the rectangular mounting ring 23 and each bottle body 11; wherein each bottle body 11 is slidably arranged on the inner wall of the heat dissipation component 24.

[0051] In the above embodiment, the first box body 2 is arranged at the lower part of the second box body 5, the top of the inner shell 21 of the first box body 2 is connected to the bottom end of the second box body 5, and the inner shell 21 and the outer shell 22 are both rectangular shells, so that the inner shell 21 can fit with the outer wall of each bottle body 11 in a rectangular array, thereby improving the stability of the installation of the bottle body 11, and further improving the problem of the quick-connect valve 13 falling off due to the shaking of the bottle body 11 when moving in the water body;

[0052] The heat dissipation component 24 is arranged on the inner wall of the rectangular mounting ring 23, the outer wall of the rectangular mounting ring 23 is fixedly mounted on the inner wall of the inner shell 21, the rectangular mounting ring 23 is concentrically arranged with the inner shell 21, and the rectangular mounting ring 23 is located in the waist area of ​​the inner shell 21, and the heat dissipation component 24 is used to cool and dissipate the heat of each bottle body 11;

[0053] It is worth stating that;

[0054] The properties of many substances in water bodies, such as microorganisms and chemicals, will change with temperature. Low temperature environment can effectively inhibit the growth and metabolic activities of microorganisms and slow down the rate of chemical reactions, thereby maintaining the original state of water samples when they are collected to the greatest extent;

[0055] Algae in water samples may continue to photosynthesize and reproduce at room temperature, causing changes in the composition and properties of the water samples. Low-temperature storage can avoid this and ensure that subsequent analysis results can accurately reflect the actual conditions of the water body at that time;

[0056] At room temperature, some easily decomposable substances in water samples may change in a short period of time, affecting the accuracy of the test. By storing water samples at low temperatures, the shelf life of the samples can be extended, providing more time for subsequent transportation and laboratory analysis. This is especially important for water samples that need to be sent to professional laboratories for complex tests, and can reduce the test errors caused by time constraints.

[0057] The design of multiple bottles 11 allows multiple sampling at different times, and the underwater heat dissipation structure can simultaneously refrigerate and preserve the water samples collected at different times, which enables the sampler to complete water sample collection for multiple time periods during one deployment process, without the need to frequently recover the sampler and replace the sampling bottle 1, greatly improving the sampling efficiency, especially for projects that require long-term continuous monitoring;

[0058] Since the water sample can be immediately stored at a low temperature after collection, it avoids the sample changes caused by factors such as temperature fluctuations, thereby reducing experimental errors. The water samples collected at different times can be stored in a stable low-temperature environment, making the subsequent analysis data more comparable and reliable.

[0059] The combination of multiple bottle bodies 11 and the low-temperature storage function enables the sampler to flexibly formulate sampling strategies according to different research purposes and requirements. For example, sampling can be carried out at different time intervals, or sampling can be concentrated during a specific time period to meet the research needs for the dynamic changes of water bodies.

[0060] With the continuous improvement of environmental monitoring requirements, it is often necessary to analyze multiple parameters of water samples. Low-temperature storage can ensure the stability of various components in the water sample, enabling the sampler to adapt to the monitoring requirements of different parameters and providing richer data for a comprehensive understanding of water quality.

[0061] Please refer to Figures 1 - 11 , in some embodiments, the heat dissipation component 24 includes: an array of rectangular aperture plates 241 disposed on the inner wall of the rectangular mounting ring 23; a plurality of rectangular apertures 242 arrayed on the surface of the array of rectangular aperture plates 241; wherein the outer wall of each bottle body 11 is slidably disposed in each rectangular aperture 242; a plurality of heat dissipation grooves 243, with multiple heat dissipation grooves 243 in pairs, and each pair of heat dissipation grooves 243 symmetrically disposed on both sides of each rectangular aperture 242; a plurality of heat dissipation fins 244 respectively disposed in each heat dissipation groove 243; wherein the heat absorption surface of the heat dissipation fin 244 is disposed close to the bottle body 11, and the heat dissipation surface is disposed in the heat dissipation groove 243. The heat dissipation component 24 further includes: a plurality of thermoelectric refrigeration chips 245 respectively disposed on the surface of each heat dissipation fin 244 close to the bottle body 11; wherein the refrigeration surface of the thermoelectric refrigeration chip 245 is disposed close to the outer wall of the bottle body 11, and the heat dissipation surface of the thermoelectric refrigeration chip 245 is connected to the heat absorption surface of the heat dissipation fin 244.

[0062] In the above embodiment, a plurality of rectangular holes 242 are provided on the surface of the array-type rectangular hole plate 241, and each rectangular hole 242 is used to install the bottle body 11. The rectangular hole 242 is in contact with the outer wall of the bottle body 11. When the thermoelectric cooling sheet 245 is working, the cooling surface cools the outer wall of the bottle body 11, so that the bottle body 11 is maintained at a relatively low temperature. The thermoelectric cooling sheet 245 is affected by the Peltier effect. When direct current passes through the thermoelectric cooling sheet 245, it will generate cooling on one side and heating on the other side. The heat absorbing surface of the heat dissipation fin 244 is connected to the heating side, so that the heat emitted by the thermoelectric cooling sheet 245 can be transferred to the outer wall of the bottle body 11 through conduction. The water sent to the heat dissipation groove 243 conducts heat to the heat dissipation fins 244 naturally through the water, and directly cools the bottle body 11 through the thermoelectric cooling sheet 245, which can quickly and effectively reduce the temperature of the bottle body 11. At the same time, the synergistic effect of the heat dissipation fins 244 and the heat dissipation groove 243 greatly increases the heat dissipation area and water flow, improves the speed of heat dissipation, and ensures the efficient operation of the entire heat dissipation system. The design of the array-type rectangular hole plate 241 is adopted, so that multiple bottles 11 can be arranged in order, and the various parts of the heat dissipation assembly 24 are arranged around the bottle body 11, and the overall structure is compact, saving space;

[0063] It is worth noting that when sampling for microbial indicators (such as total bacteria count, E. coli, etc.);

[0064] It needs to be stored at 4°C and tested within 24 hours. Low temperature can effectively inhibit bacterial activity, but cannot completely prevent reproduction. It needs to be analyzed as soon as possible, but it is necessary to take multiple continuous samples of the water area in order to observe the changes in water quality within half a day. At this time, the sample in the bottle 11 can be maintained at about 4°C through the design of the heat dissipation component 24, extending the sample storage time. The sampling equipment can be set once in the morning and evening respectively, and the total number of bacteria, E. coli, etc. in the water area can be tested for 24 hours, thereby improving the credibility of the experimental data of this project, without the need for long-term human presence or travel between the water area and the laboratory;

[0065] When sampling waters for heavy metal indicators (such as lead, cadmium, mercury, etc.);

[0066] The bottle body 11 can be replaced with a polyethylene or glass bottle. The outside of the bottle body 11 needs to be shaded. At the same time, the sampling in the bottle body 11 is maintained at about 4°C, which can extend the storage time of samples in such waters and enable continuous sampling in the water area for a long time. When continuous sampling in such waters for more than one week is required, nitric acid can be pre-added to the bottle body 11 to acidify the water sample to pH ≤ 2. After the bottle body 11 enters the water, the sample is mixed with the water sample, so that the final pH ≤ 2. The amount of the added acidified water sample can be adjusted according to actual usage requirements. It is necessary to ensure the accuracy of the added amount of the acidifying solution to avoid over-diluting the water sample or interfering with the concentration of the detected target substance. Acidifying with nitric acid to pH ≤ 2 can keep metal ions (such as silver, copper, lead, etc.) in a soluble state, preventing them from hydrolyzing to form hydroxide precipitates or adsorbing on the surface of the container, thereby ensuring the detection accuracy.

[0067] Please refer to Figures 1 - 11 , in some embodiments, the first box body 2 further includes: a first mesh plate 25, disposed at the top end of the inner shell 21 and detachably connected to the top end of the inner shell 21; wherein the first mesh plate 25 is disposed above each water inlet pipe 14, and a sampling valve assembly 8 is installed on the top surface of the first mesh plate 25; the first box body 2 further includes: a second mesh plate 26, the second mesh plate 26 is installed on the inner wall of the lower part of the inner shell 21; a third mesh plate 27, disposed below the second mesh plate 26 and installed on the inner wall of the inner shell 21; wherein both the second mesh plate 26 and the third mesh plate 27 are detachably connected to the inner wall of the inner shell 21; a card slot 28, disposed on one side of the second mesh plate 26 close to the bottle body 11, and the bottle cap 12 is clamped in the card slot 28.

[0068] In the above embodiments, the first mesh plate 25 and the second mesh plate 26 are respectively arranged at both ends of the inner shell 21 of the first box body 2. The first mesh plate 25 is used to install the sampling valve assembly 8, and the second mesh plate 26 is used to install and fix each bottle body 11 through the card slot 28. Drainage grooves are arranged on the surfaces of the first mesh plate 25, the second mesh plate 26, and the third mesh plate 27. The drainage grooves are used for water to pass through the heat dissipation grooves 243 of the arrayed rectangular hole plate 241, so that when the water flow passes through the heat dissipation fins 244, heat exchange is performed on the heat dissipation fins 244, improving the heat dissipation efficiency of the heat dissipation fins 244. The first mesh plate 25, the second mesh plate 26, and the third mesh plate 27 can not only play an installation role, but also block waterweeds, fish, shrimps, etc. in the water, avoiding waterweeds and the like from entering the first box body 2 and thus blocking the ports of the water inlet pipes 14, resulting in poor water inlet problems.

[0069] Please refer to Figures 1 - 11, in some embodiments, the second box body 5 includes: a rectangular frame 51 disposed on the upper part of the first box body 2 and spaced apart from the first box body 2; a reduced-diameter frame 52 disposed between the rectangular frame 51 and the first box body 2; wherein the small-diameter end of the reduced-diameter frame 52 is connected to the upper end wall of the inner shell 21, and the large-diameter end is connected to the lower end wall of the rectangular frame 51; the second box body 5 further includes: two support plates 53 symmetrically disposed on the upper end wall of the rectangular frame 51; wherein a second wire winding assembly 7 is disposed between the two support plates 53; a fourth mesh plate 54 disposed on the inner wall of the rectangular frame 51 and spaced apart from the first mesh plate 25; a plurality of mounting posts 55 evenly distributed between the fourth mesh plate 54 and the first mesh plate 25, and both ends of each mounting post 55 are respectively connected to the first mesh plate 25 and the second mesh plate 26.

[0070] In the above embodiments, a plurality of connecting pieces are provided between the inner shell 21 and the outer shell 22 of the first box body 2, and each connecting piece is respectively disposed at each vertex angle of the inner shell 21 and the outer shell 22. When the first box body 2 and the second box body 5 dive, each connecting piece plays a role in stabilizing the diving direction. Water flows through between the inner shell 21 and the outer shell 22. When the water flows through the inner shell 21 and the outer shell 22, it flows to the reduced-diameter frame 52 and flows upward along the outer wall of the reduced-diameter frame 52. The outer wall of the rectangular frame 51 is flush with the outer wall of the outer shell 22. The fourth mesh plate 54 is used to filter the water flowing into the inner shell 21, and a sampling valve assembly 8 is installed between the fourth mesh plate 54 and the first mesh plate 25.

[0071] Please refer to Figures 1 - 11 , in some embodiments, the heat dissipation assembly 24 further includes: a driving motor 246 disposed at the center of the top surface of the fourth mesh plate 54; an impeller 247 disposed on the output shaft of the driving motor 246; wherein the output shaft of the driving motor 246 passes through the surface of the fourth mesh plate 54 and is connected to the impeller 247.

[0072] In the above embodiments, to promote the water flow through the heat dissipation fins 244, start the driving motor 246. The output shaft of the driving motor 246 rotates to drive the impeller 247 to rotate. When the impeller 247 rotates, it drives the water to flow from the lower end of the impeller 247 upward through each heat dissipation fin 244, thereby further improving the refrigeration efficiency. When the bottle body 11 is filled with water, the buoyancy of the sampling device decreases, causing the sampling device to dive. Due to the influence of the gravity of the anchor body 3, when recovering the sampling device, each bottle body 11 is filled with water, resulting in a decrease in buoyancy. To facilitate the recovery of the sampling device, the current direction of the driving motor 246 can be changed, so that the output shaft of the driving motor 246 rotates in the opposite direction, and then the impeller 247 can stir the water body to have an upward driving force on the first box body 2 and the second box body 5, and cooperating with the second wire winding assembly 7 can improve the recovery efficiency.

[0073] Please refer to Figures 1 - 11, in some embodiments, the water source sampling device further includes: a valve driving assembly 9, which is arranged between the impeller 247 and the sampling valve assembly 8; wherein the valve driving assembly 9 includes: a first gear 91, which is arranged on the end wall of the output shaft of the driving motor 246, and the impeller 247 is arranged between the first gear 91 and the fourth mesh plate 54; a second gear 92, which meshes with one side of the first gear 91; a third gear 93, which meshes with the other side of the first gear 91; a gear mounting plate 94, with two groups provided, and the first gear 91, the second gear 92, and the third gear 93 are respectively rotatably arranged between the two groups of gear mounting plates 94; a toothed ring 95, which is sleeved outside the second gear 92 and the third gear 93 and meshes with the surfaces of the second gear 92 and the third gear 93 away from the first gear 91; two groups of electric telescopic rods 96, which are installed on the surface of the first mesh plate 25, and the electric telescopic rods 96 are arranged on both sides of the lower part of the toothed ring 95; a first friction rod 97, the mounting end of which is connected to the telescopic end of the electric telescopic rod 96, and the friction end is arranged towards the bottom surface of the toothed ring 95; a second friction rod 98, the mounting end of which is connected to the surface of the first mesh plate 25, and the friction end is arranged on the upper part of the toothed ring 95, and the friction end abuts against the surface of the toothed ring 95; a driving rod 99, one end of which is connected to the bottom surface of the toothed ring 95, and the other end is drivingly connected to the sampling valve assembly 8.

[0074] In the above embodiments, when the driving motor 246 drives the impeller 247 to rotate, the output shaft of the driving motor 246 drives the first gear 91 to rotate. When it is not necessary to drive the sampling valve assembly 8 to work, the telescopic end of the electric telescopic rod 96 extends, driving the first friction rod 97 to approach the bottom surface of the toothed ring 95, so that the friction end of the first friction rod 97 abuts against the bottom surface of the toothed ring 95, and the upper and lower surfaces of the toothed ring 95 are clamped by the first friction rod 97 and the second friction rod 98, making the toothed ring 95 unable to rotate. At this time, the second gear 92 and the third gear 93 make circular motions around the axis of the first gear 91. At the same time, affected by the meshing of the toothed ring 95, the second gear 92 and the third gear 93 rotate on their own during the circular motion;

[0075] When it is necessary to drive the sampling valve assembly 8, the telescopic end of the electric telescopic rod 96 retracts, driving the first friction rod 97 to disengage from the bottom surface of the toothed ring 95. At this time, the toothed ring 95 is not in contact with the first friction rod 97, and the friction force of the toothed ring 95 on the second gear 92 and the third gear 93 causes the toothed ring 95 to rotate. At this time, the second gear 92 and the third gear 93 rotate on their own but do not make circular motions around the axis of the first gear 91. Thus, one end of the driving rod 99 can be driven to rotate by the rotation of the toothed ring 95, and then the sampling valve assembly 8 can be driven to work by the rotation of the driving rod 99;

[0076] It should be noted that when the toothed ring 95 rotates, it needs to rely on the frictional force with the second gear 92 and the third gear 93. When driving the toothed ring 95 to rotate through the frictional force, it can avoid the deviation of the valve opening accuracy of the sampling valve assembly 8 caused by the rigid connection due to the too fast rotation speed of the output shaft of the driving motor 246, resulting in multiple bottles 11 being opened simultaneously. By controlling the telescopic movement of the electric telescopic rod 96, the rotation angle of the toothed ring 95 can be accurately controlled, further improving the control accuracy of the sampling valve assembly 8.

[0077] Please refer to Figures 1 - 11 , in some embodiments, the sampling valve assembly 8 includes: a mating rod 80 disposed at the lower part of the driving rod 99; a limiting hole 81 disposed at one end of the mating rod 80 close to the driving rod 99, and the driving rod 99 is slidably disposed in the limiting hole 81; a first sleeve 82 sleeved on the end of the mating rod 80 away from the driving rod 99; an inclined groove 83 disposed on the outer wall of the circumference of the first sleeve 82, and the inclined groove 83 is inclined; a slider 84 disposed on the outer wall of the bottom end of the mating rod 80, and the slider 84 is slidably disposed in the inclined groove 83; a second sleeve 85 disposed at the lower part of the first sleeve 82, and the bottom end of the second sleeve 85 is closed. One end of each water inlet pipe 14 away from the bottle 11 is connected to the outer wall of the circumference of the second sleeve 85, and each water inlet pipe 14 is arranged in a divergent manner with the second sleeve 85 as the center, and each water inlet pipe 14 communicates with the inner wall of the second sleeve 85; a rotating block 86 rotatably disposed in the second sleeve 85; an L-shaped hole 87 disposed in the rotating block 86, one end of the L-shaped hole 87 communicates with the side wall of the rotating block 86, and the other end communicates with the top surface of the rotating block 86; the sampling valve assembly 8 further includes a central valve assembly 88; the central valve assembly 88 is disposed between the second sleeve 85 and the upper part of the bottle 11 located below the second sleeve 85; the central valve assembly 88 includes: a plugging rod 881, the top end of which is connected to the bottom surface of the second sleeve 85; an annular groove 882 disposed on the outer wall of the circumference of the plugging rod 881, and the annular groove 882 is concentric with the plugging rod 881; a plurality of water inlet holes 883 are provided, and the plurality of water inlet holes 883 are disposed between the annular groove 882 and the bottom end of the plugging rod 881, one end of the water inlet hole 883 communicates with the inner wall of the annular groove 882, and the other end communicates with the outer wall of the bottom end of the plugging rod 881; a third sleeve 884 sleeved on the outer wall of the circumference of the plugging rod 881, and the bottom end of the third sleeve 884 is connected to the quick-connect valve 13; a water inlet groove 885 disposed on the outer wall of the circumference of the third sleeve 884; the sampling valve assembly 8 further includes: a bubble detection assembly 89, and the bubble detection assembly 89 is disposed on the surface of the first mesh plate 25; the bubble detection assembly 89 includes: an annular cover 891 disposed on the surface of the first mesh plate 25 and sleeved on the outer wall of the circumference of the first sleeve 82, and the inner wall of the annular cover 891 is spaced from the outer wall of the first sleeve 82; a plurality of air holes 892 are provided, and the plurality of air holes 892 are disposed on the surface of the first mesh plate 25, and each air hole 892 is arranged in an annular array between the first sleeve 82 and the annular cover 891; an annular plate 893, the inner wall of which is sleeved on the outer wall of the mating rod 80, and the outer wall of the annular plate 893 slides on the inner wall of the annular cover 891; a switch 894 disposed on the top surface of the annular plate 893.

[0078] In the above embodiments, when the driving rod 99 is driven to rotate by the toothed ring 95, affected by the limiting hole 81, the matching rod 80 rotates along with the rotation of the driving rod 99. The end of the driving rod 99 can be configured as a hexagonal prism, and the limiting hole 81 is configured as a hexagonal hole. Then, when disassembling the fourth mesh plate 54, the driving rod 99 can be pulled out from the limiting hole 81, or the matching rod 80 can be driven through the limiting hole 81;

[0079] When the matching rod 80 rotates, it drives the slider 84 to make a circular motion around the axis of the matching rod 80. When the slider 84 is driven and rotates, it slides in the inclined slot 83. During the sliding process of the slider 84 in the inclined slot 83, the first sleeve 82 is driven to rise. When the first sleeve 82 rises, it drives the rotating block 86 to move upward in the second sleeve 85. At this time, one end of the L-shaped hole 87 in the rotating block 86 has not reached the water inlet pipes 14 yet. During the movement of the rotating block 86, the plugging rod 881 is driven to move upward. At this time, the annular groove 882 on the plugging rod 881 is aligned with the water inlet groove 885 on the third sleeve 884, so that water enters the water inlet groove 885 and the annular groove 882, and enters the quick-connect valve 13 through the water inlet hole 883, and finally enters the bottle body 11. When the bottle body 11 at the center is filled with water, the plugging rod 881 is continuously lifted, so that the annular groove 882 on the plugging rod 881 enters the upper part of the third sleeve 884, and the outer wall of the plugging rod 881 is re-sealed with the inner wall of the third sleeve 884. If water needs to enter other bottle bodies 11, the matching rod 80 is continuously rotated, so that the matching rod 80 drives the slider 84 to continue to move until the slider 84 moves to one end of the inclined slot 83. When moving further, the slider 84 will drive the rotating block 86 to rotate. When the rotating block 86 rotates, the L-shaped hole 87 rotates around the axis of the rotating block 86, so that the bottom end of the L-shaped hole 87 communicates with one of the water inlet pipes 14, and the bottle body 11 connected to this water inlet pipe 14 starts to receive water;

[0080] The bubble detection assembly 89 is used to detect the bubbles released from the bottle body 11 through the L-shaped hole 87. When the bubbles emerge from the L-shaped hole 87, they accumulate on the lower surface of the annular plate 893. When the bubbles accumulate, the annular plate 893 rises under the buoyancy of the bubbles, thereby triggering the switch 894;

[0081] It should be noted that the switch 894 can be a push-button switch 894. By setting a single-chip microcomputer, a timer, and a driving element for the electric telescopic rod 96, the electric telescopic rod 96 can be controlled. During specific use, when the electric telescopic rod 96 drives the first friction rod 97 to disengage from the toothed ring 95, the single-chip microcomputer sends a start timing signal to the timer, and the timer starts timing. After a short period of timing ends, the single-chip microcomputer fails to recognize the level change signal transmitted from the push-button switch 894. At this time, it indicates that after the L hole 87 is docked with the water inlet pipe 14, no gas is discharged from the bottle body 11 and the bottle body 11 is not filled with water. At this time, the single-chip microcomputer sends a control signal to the driving element of the electric telescopic rod 96, causing the electric telescopic rod 96 to repeat the above action and briefly disengage from the toothed ring 95. If the push-button switch 894 still does not send a level change signal to the single-chip microcomputer within the timer interval, it means that the bubbles have not been discharged yet. Repeat the above action until the discharged bubbles lift the annular plate 893 until the switch 894 on the surface of the annular plate 893 abuts against the upper inner wall of the annular cover 891 and the switch 894 closes. The switch 894 sends a level change signal to the single-chip microcomputer. After receiving the signal, the single-chip microcomputer stops driving the electric telescopic rod 96 for the next recovery. At this time, the first friction rod 97 on the electric telescopic rod 96 abuts against the bottom surface of the toothed ring 95, the toothed ring 95 is relatively stationary, the position of the L hole 87 remains unchanged, and the water inlet pipe 14 continuously discharges gas and fills with water. When the bottle body 11 is filled with water, the bubbles under the annular plate 893 diffuse, and the annular plate 893 drives the switch 894 to move downward. When the single-chip microcomputer no longer receives the level change signal sent by the switch 894, it indicates that the bottle body 11 is filled with water at this time.

[0082] Please refer to Figures 1 - 11, in some embodiments, both the first wire winding assembly 4 and the second wire winding assembly 7 include: a wire take-up roller 41, a wire take-up motor 42, a screw 43, and a pull rope 44; a bidirectional thread 47 is provided on the outer peripheral wall of the screw 43; a collar 45 is sleeved on the outer peripheral wall of the screw 43; a guide rod 46, one end of which is rotatably connected to the inner wall of the collar 45 and the other end of which is slidably arranged in the bidirectional thread 47; wherein the wire take-up roller 41 of the first wire winding assembly 4 is rotatably installed on the inner wall of the inner shell 21, and one end of the wire take-up roller 41 of the first wire winding assembly 4 passes through the outer shell 22 and is connected to the output shaft of the wire take-up motor 42; both ends of the screw 43 of the first wire winding assembly 4 are connected to the inner wall of the outer shell 22; one end of the pull rope 44 of the first wire winding assembly 4 is wound around the outer peripheral wall of the wire take-up roller 41, and the other end passes through the outer wall of the collar 45 and is connected to the anchor body 3; the wire take-up roller 41 and the screw 43 of the second wire winding assembly 7 are respectively rotatably installed between the two support plates 53; the wire take-up roller 41 of the second wire winding assembly 7 passes through the support plate 53 and is connected to the output shaft of the wire take-up motor 42; one end of the pull rope 44 of the second wire winding assembly 7 is wound around the outer peripheral wall of the wire take-up roller 41, and the other end passes through the outer wall of the collar 45 and is connected to the photovoltaic buoy assembly 6; a buckle 71 is provided at one end of the support plate 53 away from the rectangular frame 51; the buckle 71 is detachably connected to the support plate 53; the screw 43 and the wire take-up roller 41 of the second wire winding assembly 7 are arranged below the buckle 71; the photovoltaic buoy assembly 6 includes: an airbag 61 floating on the water surface; a photovoltaic panel 62 provided on the surface of the airbag 61; a storage battery 63 installed between the inner shell 21 and the outer shell 22; a plurality of stainless steel electrodes 64, and the plurality of stainless steel electrodes 64 are respectively provided on the surfaces of the third mesh plate 27 and the fourth mesh plate 54; wherein the photovoltaic panel 62 is electrically connected to the storage battery 63, and the stainless steel electrodes 64 are electrically connected to the storage battery 63.

[0083] In the above embodiments, the working modes of the first wire winding assembly 4 and the second wire winding assembly 7 are similar. For example, when the first wire winding assembly 4 works, the winding electrode drives the wire take-up roller 41 to rotate. When the second wire winding assembly 7 works, it drives its wire take-up roller 41 to rotate. When the wire take-up roller 41 rotates, the pull rope 44 is continuously wound around the outer peripheral wall of the wire take-up roller 41. During the winding process of the pull rope 44, the collar 45 continuously rotates on the screw 43. Affected by the movement of the guide rod 46 in the bidirectional thread 47, the collar 45 reciprocates along the length direction of the screw 43 during the rotation along the screw 43, so as to wind the pull rope 44 evenly on the outer wall of the wire take-up roller 41;

[0084] The photovoltaic panel 62 generates electricity to supply power to the storage battery 63, and at the same time supplies power to the drive motor 246, the winding motor, and the stainless steel electrodes 64 through the storage battery 63. When the stainless steel electrodes 64 are powered on, a low-voltage electric field is formed around the third mesh plate 27 and the fourth mesh plate 54, which can achieve the effect of driving away nearby fish and shrimps.
