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 vital task. The sample data obtained is of great significance for understanding water quality conditions and studying the water ecological environment.

[0003] At present, the existing water source sampling equipment mainly relies on manual water extraction. In actual operation, it is often necessary to conduct multiple sampling of the water area at different depths and different time periods. For example, when studying the vertical stratification structure of the water body, it is necessary to collect water samples at different depths; when analyzing the changes in water quality over time, sampling work must be carried out at different time periods.

[0004] However, the existing water sampling equipment is difficult to meet such needs. On the one hand, it does 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 but also difficult to ensure accuracy. On the other hand, for multiple samplings in different time periods, the existing equipment 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 lot of manpower, material resources and time, but may also affect the accuracy and scientificity of the sample data due to factors such as inaccurate sampling intervals, which seriously restricts the efficiency and quality of water sampling work.

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

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

[0018] When the sampling device is used for continuous water quality sampling, the sampling device can be thrown into the water body by a drone. When the sampling device finishes sampling, the photovoltaic buoy component can be identified by the drone and the sampling device can be salvaged; When the sampling device is placed in the water body, the first winding assembly releases the line so that the anchor body falls to the bottom of the water to prevent the sampling device from leaving the sampling area due to too fast water flow rate. Since each sampling bottle is full of air, the buoyancy of the sampling device is the largest at this time, which is recorded as the first sampling depth. The sampling valve assembly is started, and the external water body and one of the sampling bottles are connected through a pipeline, so that one of the multiple sampling bottles is filled with water. The sampling bottle continuously exhausts air upward during the process of filling water, which reduces the buoyancy of the sampling device. The first box and the second box continue to dive, and the second winding assembly releases the line so that the photovoltaic buoy assembly floats on the water surface. During the diving process, the first winding assembly starts to reel in the line, which reduces the distance between the anchor body and the first box to prevent the first box from moving a long distance due to the water flow caused by the first winding assembly paying out too long. When the air in the first sampling bottle is completely discharged, the sampling valve assembly is closed. The first box and the second box dive to the second sampling depth. After a period of time, the sampling valve assembly opens again, and the second sampling bottle is connected to the external water body. The second sampling bottle starts to exhaust gas and take in water. At this time, the first winding assembly and the second winding assembly repeat the above actions, so that after the buoyancy of the sampling equipment becomes smaller, the first box and the second box continue to dive slowly. When the gas in the second sampling bottle is completely discharged, the first box and the second box dive to the third sampling depth. Repeating the above actions can sample through each sampling bottle in turn to achieve 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 winding assembly and the first winding assembly can also be used to reel in and release the line, and the photovoltaic buoy assembly can be used to provide buoyancy to the first box and the second box, so that the sampling bottle can be suspended at the specified depth for multiple samplings at different time periods; Multiple sampling bottles can be filled with water independently and can automatically sample at different depths according to changes in buoyancy, which allows the device to obtain water samples at different depths of the water body. Water at different depths may differ in temperature, dissolved oxygen, microbial communities, chemical concentrations, etc. Stratified sampling helps to fully understand the vertical structure and water quality distribution characteristics of the water body, which is of great significance for studying the water ecosystem and evaluating the spread and migration of pollution. At the same time, the buoyancy change of the sampling bottle after collection is used to realize automatic interval sampling, without the need for frequent manual operation, which not only saves labor costs but also ensures the accuracy and consistency of the sampling time interval; In some projects that require long-term continuous monitoring, such as studying the seasonal changes of water bodies and the impact of tides on water quality, this automatic interval sampling function can provide more scientific and accurate data. It can use photovoltaic buoy components for suspended sampling at the same depth, and can perform sampling in different time periods. This is helpful to study the changes in water quality over time at the same depth, such as the dynamic changes in water quality at different times of the day and under different weather conditions. At the same time, multiple sampling can increase the number and representativeness of samples and improve the reliability of data analysis. The buoy suspension sampling method allows the equipment 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, sampling can be achieved as long as the appropriate buoy is placed, which has strong adaptability and flexibility.

DETAILED DESCRIPTION

[0034] In order to make the purpose, scheme and advantages of the technical solution of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described in conjunction with the drawings of the specific embodiments of the present invention. Unless otherwise specified, the terms used herein have the usual meanings in the art. The same reference numerals in the drawings represent the same components.

[0035] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" 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 it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] As described above, in the use of traditional water source sampling equipment, the existing sampling equipment cannot achieve continuous multiple sampling, resulting in low sampling efficiency.

[0037] In order to at least partially solve one or more of the above problems and other potential problems, an exemplary embodiment of the present invention provides a storage water source sampling device for environmental detection, see Figure 1-Figure 11 The water source sampling equipment includes: a sampling bottle 1, of which there are multiple ones; a first box body 2, in which each sampling bottle 1 is arrayed; an anchor body 3, arranged at the lower part of the first box body 2; a first winding assembly 4, arranged between the anchor body 3 and the first box body 2; a second box body 5, arranged at the upper end of the first box body 2; a sampling valve assembly 8, arranged in the second box body 5, and the sampling valve assembly 8 is connected to each sampling bottle 1 tube; a photovoltaic buoy assembly 6, floating on the water surface; a second winding assembly 7, arranged between the photovoltaic buoy assembly 6 and the second box body 5.

[0038] In the above embodiment, when the sampling device is used for continuous water quality sampling, the sampling device can be thrown into the water body by a drone. When the sampling device finishes sampling, the photovoltaic buoy assembly 6 can be identified by the drone and the sampling device can be salvaged; When the sampling device is placed in the water body, the first winding assembly 4 releases the line so that the anchor body 3 falls to the bottom of the water, so as to prevent the sampling device from leaving the sampling area due to too fast water flow rate. Since each sampling bottle 1 is full of air, the buoyancy of the sampling device is the largest at this time, which is recorded as the first sampling depth. The sampling valve assembly 8 is started, and the external water body and one of the sampling bottles 1 are connected through a pipeline, so that one of the multiple sampling bottles 1 is filled with water. The sampling bottle 1 continuously exhausts air upward during the process of filling water, so that the buoyancy of the sampling device becomes smaller, and the first box body 2 and the second box body 5 continue to dive, and the second winding assembly 7 releases the line so that the photovoltaic buoy assembly 6 floats on the water surface. During the diving process, the first winding assembly 4 starts to reel in the line, so that the distance between the anchor body 3 and the first box body 2 is reduced, so as to prevent the first box body 2 from moving a long distance due to the water flow caused by the first winding assembly 4 releasing the line too long. When the air in the first sampling bottle 1 is completely discharged, the sampling valve assembly 8 is closed. The first box 2 and the second box 5 dive to the second sampling depth. After a period 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 begins to exhaust gas and take in water. At this time, the first winding assembly 4 and the second winding assembly 7 repeat the above-mentioned actions, so that after the buoyancy of the sampling equipment becomes smaller, the first box 2 and the second box 5 continue to dive slowly. When the gas in the second sampling bottle 1 is completely discharged, the first box 2 and the second box 5 dive to the third sampling depth. Repeating the above-mentioned actions can sample through each sampling bottle 1 in turn to achieve 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 winding assembly 7 and the first winding assembly 4 can also be used to reel in and release the line, and the photovoltaic buoy assembly 6 can be used to provide buoyancy to the first box 2 and the second box 5, so that the sampling bottle 1 can be suspended at a specified depth for multiple samplings at different time periods; Multiple sampling bottles 1 can independently take in water and automatically take samples at different depths according to changes in buoyancy, which enables the device to obtain water samples at different depths of the water body. Water at different depths may differ in temperature, dissolved oxygen, microbial communities, chemical substance concentrations, etc. Stratified sampling helps to fully understand the vertical structure and water quality distribution characteristics of the water body, which is of great significance for studying the water ecosystem, assessing pollution diffusion and migration, etc.; At the same time, the buoyancy change of the sampling bottle 1 after collection is used to realize automatic interval sampling, without frequent manual operation, which not only saves labor costs but also ensures the accuracy and consistency of the sampling time interval; In some projects that require long-term continuous monitoring, such as studying the seasonal changes of water bodies and the impact of tides on water quality, this automatic interval sampling function can provide more scientific and accurate data. The photovoltaic buoy component 6 can be used for suspended sampling at the same depth, and sampling can be performed in different time periods. This is helpful to study the changes in water quality over time at the same depth, such as the dynamic changes in water quality at different times of the day and under different weather conditions. At the same time, multiple sampling can increase the number and representativeness of samples and improve the reliability of data analysis. The buoy suspension sampling method allows the equipment 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, sampling can be achieved as long as a suitable buoy is placed, which has strong adaptability and flexibility.

[0039] See also Figure 1-Figure 11 In some embodiments, the sampling bottle 1 includes: a bottle body 11, which is a rectangular structure; a bottle cap 12, which is arranged on the lower end surface of the bottle body 11 and is threadedly connected to the bottle mouth of the bottle body 11; a quick-connect valve 13, which is arranged 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 of which 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.

[0040] In the above embodiment, the bottle body 11 of each sampling bottle 1 is configured as a rectangular parallelepiped structure. When the bottle bodies 11 with rectangular parallelepiped structures are arrayed in the first box body 2, they are more stable than cylindrical barrel bodies. The sampling bottles 1 have a higher fit between each other and are not prone to collision and twisting in the box body, thereby improving the problem that the sampling bottle 1 is easy to fall off from the quick-connect valve 13. The sampling valve assembly 8 is located above the bottle body 11, and the 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, so that the sampling valve assembly 8 is easier to control the collection work of each bottle body 11, and there is no need to install a solenoid valve on each bottle body 11, thereby reducing costs while improving the reliability of the equipment and avoiding the failure of some bottles 11 due to solenoid valve failure. Regarding the problem of normal collection, when the collection work is completed and the sampling equipment is salvaged, the first box body 2 and the second box body 5 are placed on the laboratory table, with the end of each bottle body 11 with the bottle cap 12 facing downward. After taking out the sampling valve assembly 8 in the second box body 5, the upper part of each bottle body 11 is exposed, the water inlet pipe 14 is removed from the quick-connect valve 13, and the bottle body 11 is moved vertically. When it is necessary to experiment on the sample in the bottle body 11, it is only necessary to seal the quick-connect valve 13 with your fingers and unscrew the bottle cap 12. After placing the bottle body 11 on top of the measuring cup, remove your fingers 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 not only avoids contamination of the samples in each bottle body 11, but also improves the experimental efficiency.

[0041] See also Figure 1-Figure 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.

[0042] 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; 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; It is worth stating that; 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; 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; 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. 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; Since water samples can be stored at low temperatures immediately after collection, sample changes caused by temperature fluctuations and other factors are avoided, thereby reducing experimental errors. Water samples collected at different times can be stored in a stable low-temperature environment, making subsequent analysis data more comparable and reliable; The combination of multiple bottles 11 and the low-temperature preservation function allows the sampler to flexibly formulate sampling strategies according to different research purposes and needs. For example, sampling can be performed at different time intervals, or concentrated sampling can be performed in a specific time period to meet the research needs of dynamic changes in water bodies; 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 water samples, allowing the sampler to adapt to the monitoring needs of different parameters and provide richer data for a comprehensive understanding of water quality.

[0043] See also Figure 1-Figure 11 In some embodiments, the heat dissipation assembly 24 includes: an array-type rectangular hole plate 241, which is arranged on the inner wall of the rectangular mounting ring 23; a plurality of rectangular holes 242, which are arranged in an array on the surface of the array-type rectangular hole plate 241; wherein the outer wall of each bottle body 11 is slidably arranged in each rectangular hole 242; a plurality of heat dissipation grooves 243, which are arranged in groups of two, and each group of heat dissipation grooves 243 is symmetrically arranged on both sides of each rectangular hole 242; a plurality of heat dissipation fins 244, which are arranged in a plurality of heat dissipation fins. The fins 244 are respectively arranged in each heat dissipation groove 243; wherein the heat absorption surface of the heat dissipation fin 244 is arranged close to the bottle body 11, and the heat dissipation surface is arranged in the heat dissipation groove 243. The heat dissipation component 24 also includes: a thermoelectric cooling sheet 245, which is provided with multiple thermoelectric cooling sheets 245, and the multiple thermoelectric cooling sheets 245 are respectively arranged on one side of each heat dissipation fin 244 close to the bottle body 11; wherein the cooling surface of the thermoelectric cooling sheet 245 is arranged close to the outer wall of the bottle body 11, and the heat dissipation surface of the thermoelectric cooling sheet 245 is connected to the heat absorption surface of the heat dissipation fin 244.

[0044] 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; It is worth noting that when sampling for microbial indicators (such as total bacteria count, E. coli, etc.); 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; When sampling waters for heavy metal indicators (such as lead, cadmium, mercury, etc.); The bottle 11 can be replaced with a polyethylene or glass bottle, and the outside of the bottle 11 needs to be shading treated. At the same time, the sample in the bottle 11 is maintained at about 4°C, which can extend the storage time of samples in such waters and allow continuous sampling in waters for a long time. If such waters need to be sampled continuously for more than one week, nitric acid can be pre-added to the bottle 11 to acidify the water sample to a pH of ≤2. After the bottle 11 is filled with water underwater, the sample is mixed with the water sample to make the final pH ≤2. The amount of acidified water sample added can be adjusted according to actual usage requirements. It is necessary to ensure that the amount of acidified liquid added is accurate to avoid excessive dilution of the water sample or interference with the concentration of the target object to be detected. Acidification with nitric acid to a pH of ≤2 can keep metal ions (such as silver, copper, lead, etc.) soluble and prevent them from being hydrolyzed to form hydroxide precipitation or adsorbed on the surface of the container, thereby ensuring detection accuracy.

[0045] See also Figure 1-Figure 11 In some embodiments, the first box body 2 also includes: a first mesh plate 25, which is arranged at the top of the inner shell 21 and is detachably connected to the top of the inner shell 21; wherein the first mesh plate 25 is arranged at the upper part of each water inlet pipe 14, and the sampling valve assembly 8 is installed on the top surface of the first mesh plate 25; the first box body 2 also includes: a second mesh plate 26, and the second mesh plate 26 is installed on the lower inner wall of the inner shell 21; a third mesh plate 27, which is arranged at the lower part of the second mesh plate 26 and is installed on the inner wall of the inner shell 21; wherein the second mesh plate 26 and the third mesh plate 27 are both detachably connected to the inner wall of the inner shell 21; a card slot 28, which is arranged on the side of the second mesh plate 26 close to the bottle body 11, and the bottle cap 12 is carded in the card slot 28.

[0046] In the above embodiment, the first mesh plate 25 and the second mesh plate 26 are respectively provided 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 each bottle body 11 for fixing through the card slot 28, and the surfaces of the first mesh plate 25, the second mesh plate 26, and the third mesh plate 27 are all provided with water-permeable grooves, and the drainage grooves are used for water to pass through the heat dissipation grooves 243 of the array-type rectangular hole plate 241, so that when the water flows through the heat dissipation fins 244, the heat exchange is performed on the heat dissipation fins 244, thereby 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 can block aquatic plants, fish and shrimps in the water body, and prevent the aquatic plants and the like from entering the first box body 2, thereby blocking the port of the water inlet pipe 14 and causing the problem of poor water inlet.

[0047] See also Figure 1-Figure 11 In some embodiments, the second box body 5 includes: a rectangular frame 51, which is arranged on the upper part of the first box body 2 and is spaced apart from the first box body 2; a variable diameter frame 52, which is arranged between the rectangular frame 51 and the first box body 2; wherein the small diameter end of the variable 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 also includes: a support plate 53, which is provided with two groups, and the two groups of support plates 53 are symmetrically arranged on the upper end wall of the rectangular frame 51; wherein a second winding assembly 7 is arranged between the two groups of support plates 53; a fourth mesh plate 54, which is provided on the inner wall of the rectangular frame 51 and is spaced apart from the first mesh plate 25; a plurality of mounting columns 55 are provided, and the plurality of mounting columns 55 are evenly distributed between the fourth mesh plate 54 and the first mesh plate 25, and the two ends of each mounting column 55 are respectively connected to the first mesh plate 25 and the second mesh plate 26.

[0048] In the above embodiment, a plurality of connecting plates are provided between the inner shell 21 and the outer shell 22 of the first box body 2, and each connecting plate is respectively arranged at each vertex 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 plate plays a role in stabilizing the diving direction, and the 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 variable diameter frame 52 and flows upward along the outer wall of the variable 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 flow entering the inner shell 21, and the sampling valve assembly 8 is installed between the fourth mesh plate 54 and the first mesh plate 25.

[0049] See also Figure 1-Figure 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.

[0050] In the above embodiment, in order to promote water flow through the heat dissipation fins 244, the drive motor 246 is started, and the output shaft of the drive motor 246 rotates to drive the impeller 247 to rotate. When the impeller 247 rotates, the water flow is driven from the lower end of the impeller 247 from bottom to top 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 equipment is reduced, causing the sampling equipment to dive. Due to the influence of the gravity of the anchor body 3, when the sampling equipment is recovered, each bottle body 11 is filled with water, resulting in a smaller buoyancy. In order to facilitate the recovery of the sampling equipment, the current direction of the drive motor 246 can be changed so that the output shaft of the drive 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. In conjunction with the second winding assembly 7, the recovery efficiency can be improved.

[0051] See also Figure 1-Figure 11In some embodiments, the water source sampling device further includes: a valve drive assembly 9, the valve drive assembly 9 is arranged between the impeller 247 and the sampling valve assembly 8; wherein the valve drive assembly 9 includes: a first gear 91, arranged on the output shaft end wall of the driving motor 246, the impeller 247 is arranged between the first gear 91 and the fourth mesh plate 54; a second gear 92, meshed with one side of the first gear 91; a third gear 93, meshed with the other side of the first gear 91; a gear mounting plate 94, provided with two groups, 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 gear ring 95, sleeved on the second gear The wheel 92 is meshed with the outer side of the third gear 93 and the second gear 92 and the third gear 93 away from the first gear 91; the electric telescopic rod 96 is provided with two groups, and the two groups of electric telescopic rods 96 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 gear ring 95; the 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 toward the bottom surface of the gear ring 95; the second friction rod 98, the mounting end of which is connected to the surface of the first mesh plate 25, the friction end is arranged on the upper part of the gear ring 95, and the friction end abuts against the surface of the gear ring 95; the driving rod 99, one end of which is connected to the bottom surface of the gear ring 95, and the other end is drivingly connected to the sampling valve assembly 8.

[0052] In the above embodiment, when the driving motor 246 drives the impeller 247 to rotate, the first gear 91 is driven to rotate through the output shaft of the driving motor 246. When there is no need to drive the sampling valve assembly 8 to work, the telescopic end of the electric telescopic rod 96 is extended, driving the first friction rod 97 to approach the bottom surface of the gear ring 95, so that the friction end of the first friction rod 97 abuts against the bottom surface of the gear ring 95, and the first friction rod 97 and the second friction rod 98 clamp the upper and lower surfaces of the gear ring 95, so that the gear ring 95 cannot rotate. At this time, the second gear 92 and the third gear 93 make a circular motion around the axis of the first gear 91. At the same time, the second gear 92 and the third gear 93 are affected by the meshing of the gear ring 95 and rotate in the process of making a circular motion. When the sampling valve assembly 8 needs to be driven, the telescopic end of the electric telescopic rod 96 is retracted, driving the first friction rod 97 to disengage from the bottom surface of the gear ring 95. At this time, the gear ring 95 is not in contact with the first friction rod 97. The friction force of the gear ring 95 on the second gear 92 and the third gear 93 causes the gear ring 95 to rotate. At this time, the second gear 92 and the third gear 93 rotate but do not make a circular motion around the axis of the first gear 91. Therefore, the rotation of the gear ring 95 drives one end of the driving rod 99 to rotate, and then the driving rod 99 can be rotated to drive the sampling valve assembly 8 to work; It is worth noting that when the gear ring 95 rotates, it needs to rely on the friction between the second gear 92 and the third gear 93. When the gear ring 95 is driven to rotate by the friction force, it can avoid the rigid connection causing the sampling valve assembly 8 to be driven due to the excessively fast output shaft speed of the driving motor 246, resulting in the valve opening accuracy deviation after the sampling valve assembly 8 is driven, so that multiple bottles 11 are opened at the same time. By controlling the extension and retraction of the electric telescopic rod 96, the rotation angle of the gear ring 95 can be accurately controlled, further improving the control accuracy of the sampling valve assembly 8.

[0053] See also Figure 1-Figure 11 In some embodiments, the sampling valve assembly 8 includes: a matching rod 80, which is arranged at the lower part of the driving rod 99; a limiting hole 81, which is arranged at one end of the matching rod 80 close to the driving rod 99, and the driving rod 99 is slidably arranged in the limiting hole 81; a first sleeve 82, which is sleeved on the end of the matching rod 80 away from the driving rod 99; an inclined groove 83, which is arranged on the circumferential outer wall of the first sleeve 82, and the inclined groove 83 is inclined; a slider 84, which is arranged on the outer wall of the bottom end of the matching rod 80, and the slider 84 is slidably arranged in the inclined groove 83; a second sleeve 85, which is arranged at the lower part of the first sleeve 82, and the bottom end of the second sleeve 85 is closed, and each water inlet pipe 14 is away from the bottle body 1 1 are connected to the circumferential outer wall of the second sleeve 85, and each water inlet pipe 14 is arranged divergently with the second sleeve 85 as the center, and each water inlet pipe 14 is connected to the inner wall of the second sleeve 85; a rotary block 86 is rotatably arranged in the second sleeve 85; an L hole 87 is arranged in the rotary block 86, one end of the L hole 87 is connected to the side wall of the rotary block 86, and the other end is connected to the top surface of the rotary block 86; the sampling valve assembly 8 also includes a central valve assembly 88; the central valve assembly 88 is arranged between the second sleeve 85 and the upper part of the bottle body 11 located below the second sleeve 85; the central valve assembly 88 includes: a plug-in rod 881, the top end of which is connected to the bottom of the second sleeve 85 881, an annular groove 882 is arranged on the circumferential outer wall of the plug-in rod 881, and the annular groove 882 is arranged concentrically with the plug-in rod 881; a plurality of water inlet holes 883 are provided, and a plurality of water inlet holes 883 are arranged between the annular groove 882 and the bottom end of the plug-in rod 881, one end of the water inlet hole 883 is connected to the inner wall of the annular groove 882, and the other end is connected to the outer wall of the bottom end of the plug-in rod 881; a third sleeve 884 is sleeved on the circumferential outer wall of the plug-in rod 881, and the bottom end of the third sleeve 884 is connected to the quick-connect valve 13; a water inlet groove 885 is arranged on the circumferential outer wall of the third sleeve 884; the sampling valve assembly 8 also includes: a bubble detection assembly 89, a bubble The detection component 89 is arranged on the surface of the first mesh plate 25; the bubble detection component 89 includes: an annular cover 891, which is arranged on the surface of the first mesh plate 25 and is sleeved on the circumferential outer wall of the first sleeve 82, and the inner wall of the annular cover 891 is spaced apart 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 arranged 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 matching rod 80, and the outer wall of the annular plate 893 slides on the inner wall of the annular cover 891; a switch 894 is arranged on the top surface of the annular plate 893.

[0054] In the above embodiment, when the driving rod 99 is driven to rotate by the gear ring 95, the matching rod 80 rotates along with the driving rod 99 under the influence of the limiting hole 81. The end of the driving rod 99 can be configured as a hexagonal prism, and the limiting hole 81 can be configured as a hexagonal hole. Then, when the fourth mesh plate 54 is disassembled, the driving rod 99 can be pulled out of the limiting hole 81, and the matching rod 80 can also be driven through the limiting hole 81. When the matching rod 80 rotates, the slider 84 is driven to make a circular motion around the axis of the matching rod 80. When the slider 84 is driven and rotated, it slides in the inclined groove 83. During the sliding process of the slider 84 in the inclined groove 83, the first sleeve 82 is driven to rise. When the first sleeve 82 rises, the rotary block 86 is driven to move upward in the second sleeve 85. At this time, one end of the L hole 87 in the rotary block 86 has not yet reached the water inlet pipes 14. During the movement of the rotary block 86, the plug-in rod 881 is driven to move upward. At this time, the annular groove 882 on the plug-in rod 881 is aligned with the water inlet groove 885 on the third sleeve 884, so that the 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. Finally, After the bottle 11 is filled with water, the plug-in rod 881 is continuously lifted, so that the annular groove 882 on the plug-in rod 881 enters the upper part of the third sleeve 884, and the outer wall of the plug-in rod 881 and the inner wall of the third sleeve 884 are re-sealed. If water needs to be introduced into 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 groove 83. When the slider 84 continues to move, the slider 84 drives the rotary block 86 to rotate. When the rotary block 86 rotates, the L hole 87 rotates around the axis of the rotary block 86, so that the bottom end of the L hole 87 is connected to one of the water inlet pipes 14. At this time, the bottle 11 connected to the water inlet pipe 14 starts to be filled with water. The bubble detection assembly 89 is used to detect bubbles released from the L hole 87 from the bottle body 11. When bubbles emerge from the L hole 87, they accumulate on the lower surface of the annular plate 893. After the bubbles accumulate, the annular plate 893 rises due to the buoyancy of the bubbles, thereby triggering the switch 894. It is worth noting that the switch 894 may optionally include a button switch 894. By setting a single-chip microcomputer, a timer, and a driving element of the electric telescopic rod 96, the electric telescopic rod 96 is controlled. In specific use, when the electric telescopic rod 96 drives the first friction rod 97 to disengage from the gear ring 95, the single-chip microcomputer sends a start timing signal to the timer, and the timer starts timing. After a short timing, the single-chip microcomputer fails to recognize the level change signal from the button switch 894. At this time, it means that after the L hole 87 and the water inlet pipe 14 are connected, no gas is discharged from the bottle body 11, and no water enters the bottle body 11. At this time, the single-chip microcomputer sends a control signal to the driving element of the electric telescopic rod 96, so that the electric telescopic rod 96 repeats the above action and temporarily disengages from the gear ring 95. If the button switch 894 has not sent a level change signal to the single-chip microcomputer within the timer interval, the bottle body 11 will be deactivated. If a signal is received, it means that the bubbles have not been discharged yet. The above-mentioned action is repeated until the discharged bubbles lift the annular plate 893, and the switch 894 on the surface of the annular plate 893 abuts against the upper inner wall of the annular cover 891, and then the switch 894 is closed. 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 gear ring 95, the gear ring 95 is relatively inhibited, the position of the L hole 87 remains unchanged, and the water inlet pipe 14 continues to discharge gas and inlet water. When the bottle body 11 is full of 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 full of water.

[0055] See also Figure 1-Figure 11In some embodiments, the first winding assembly 4 and the second winding assembly 7 both include: a take-up roller 41, a take-up motor 42, a screw 43, and a pull rope 44; the circumferential outer wall of the screw 43 is provided with a bidirectional thread 47; a ring 45, which is sleeved on the circumferential outer wall of the screw 43; a guide rod 46, one end of which is rotatably connected to the inner wall of the ring 45, and the other end is slidably arranged in the bidirectional thread 47; wherein the take-up roller 41 of the first winding assembly 4 is rotatably installed on the inner wall of the inner shell 21, and one end of the take-up roller 41 of the first winding assembly 4 passes through the outer shell 22 and is connected to the output shaft of the take-up motor 42; both ends of the screw 43 of the first winding assembly 4 are connected to the inner wall of the outer shell 22; one end of the pull rope 44 of the first winding assembly 4 is wound around the circumferential outer wall of the take-up roller 41, and the other end passes through the outer wall of the ring 45 to connect to the anchor body 3; the take-up roller 41 and the screw 43 of the second winding assembly 7 are rotatably installed between the two support plates 53 The take-up roller 41 of the second winding assembly 7 passes through the support plate 53 and is connected to the output shaft of the take-up motor 42; one end of the pull rope 44 of the second winding assembly 7 is wound around the circumferential outer wall of the take-up roller 41, and the other end passes through the outer wall of the ring 45 to connect to the photovoltaic buoy assembly 6; a buckle 71 is provided at the 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 take-up roller 41 of the second winding assembly 7 are arranged at the lower part of the buckle 71; the photovoltaic buoy assembly 6 includes: an airbag 61, floating on the water surface; a photovoltaic panel 62, arranged on the surface of the airbag 61; a battery 63, installed between the inner shell 21 and the outer shell 22; a plurality of stainless steel electrodes 64, and a plurality of stainless steel electrodes 64 are respectively arranged 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 battery 63, and the stainless steel electrode 64 is electrically connected to the battery 63.

[0056] In the above embodiment, the working modes of the first winding assembly 4 and the second winding assembly 7 are similar. For example, when the first winding assembly 4 is working, the winding electrode drives the take-up roller 41 to rotate, and when the second winding assembly 7 is working, it drives its take-up roller 41 to rotate. When the take-up roller 41 rotates, the pull rope 44 is continuously wound around the circumferential outer wall of the take-up roller 41. During the winding process of the pull rope 44, the ring 45 continuously rotates on the screw 43. Affected by the movement of the guide rod 46 in the bidirectional thread 47, the ring 45 reciprocates along the length direction of the screw 43 during the rotation of the screw 43, thereby evenly winding the pull rope 44 around the outer wall of the take-up roller 41. The photovoltaic panel 62 generates electricity to supply power to the battery 63, and the battery 63 also supplies power to the drive motor 246, the winding motor, and the stainless steel electrode 64. When the stainless steel electrode 64 is energized, 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 shrimp.
