Description

Technical Field

[0001] This invention relates to the technical field of water source sampling, and in particular to a water source sampling device and sampling method for monitoring the aquatic ecological environment. Background Technology

[0002] As an important foundation for water resource protection and pollution prevention and control, the quality of water ecological environment monitoring data directly affects the accuracy of ecological assessment and the scientific nature of management decisions. Water source sampling, as the core link of monitoring, needs to obtain water samples with spatiotemporal representativeness through standardized technical means to reflect the true state of the water body's chemical, biological and physical characteristics.

[0003] However, during the water sampling process, the sampling device usually only has a single sampling effect, such as sampling only filtered water to measure turbidity interference absorbance, or sampling only unfiltered water to detect microorganisms, algae and plankton in the water. It cannot sample two types of water samples at the same time, so it is necessary to conduct multiple samplings and use different types of sampling devices. Summary of the Invention

[0038] Example 1

[0039] Reference Figures 1-6 The first embodiment of the present invention provides a sampling method for a water source sampling device for monitoring aquatic ecological environment, which enables the collection of both turbid and clear water samples in a single water sample collection to ensure the accuracy and diversity of the detection data.

[0040] First, the sampling device 100 is inserted into the water, allowing water to enter the sampling device 100 for sampling.

[0041] The clear sampling component 102 can filter and collect the incoming water, ensuring that the collected water sample is clear enough.

[0042] The turbidity sampling component 103 is used to directly receive and turbid the water, making the distribution of microorganisms, algae and plankton more uniform.

[0043] During the sampling process, the cleaning mechanism 200 is activated to clean the clear sampling component 102, ensuring liquid inlet efficiency and preventing clogging at the filter, which would affect the sampling efficiency.

[0044] Example 2

[0045] Reference Figures 1-4 In the second embodiment of the present invention, a sampling mechanism 100 is provided to simultaneously collect clear water samples and turbid water samples.

[0046] The sampling mechanism 100 includes a sampling box 101, a clear sampling component 102, and a turbid sampling component 103. A top plate 104 is movably mounted on the top of the sampling box 101. The clear sampling component 102 includes two clear sampling cylinders 102a. The bottom of each clear sampling cylinder 102a is movably connected to both sides of the bottom of the inner wall of the sampling box 101. A first liquid inlet hole 102b is provided on both sides of the top of the top plate 104. Filter paper 102c is disposed inside the first liquid inlet hole 102b, and an mounting sleeve 102d is fitted onto the surface of the filter paper 102c. The surface of 2d is movably connected to the inner wall of the first liquid inlet 102b. The top of the clear sampling cylinder 102a is movably connected to a plastic guide bag 102e, and the top of the plastic guide bag 102e is connected to the first liquid inlet 102b. The turbid sampling assembly 103 includes a turbid sampling cylinder 103a. The bottom of the turbid sampling cylinder 103a is fixedly connected to the bottom of the inner wall of the sampling box 101. A waterproof motor 103b is provided on the top of the turbid sampling cylinder 103a. A transmission component 103c is fixedly connected to the output end of the waterproof motor 103b. A mixing rod 103d is fixedly connected to the bottom of the transmission component 103c. The mixing rod 103d is located inside the turbid sampling cylinder 103a. A second liquid inlet 103e is provided at the top of the inner wall of the sampling box 101. Three second liquid inlets 103e are provided and are distributed in a ring at equal intervals. Centrifugal components 103f are fixedly connected to both sides of the bottom of the transmission component 103c. The centrifugal component 103f includes a connecting sleeve 103f-1, the top of which is fixedly connected to both sides of the bottom of the transmission component 103c. A transmission ring 103f-2 is fitted onto the surface of the clear sampling assembly 102. The inner side of the transmission ring 103f-2 is connected to the connecting sleeve 103f-1. The inner wall is slidably connected, and the outer side of the transmission ring 103f-2 is fixedly connected to the limiting block 103f-3. The bottom of the inner wall surface of the sampling box 101 is provided with an annular limiting groove 103f-4. The inner wall of the annular limiting groove 103f-4 is slidably connected to the surface of the limiting block 103f-3. The surface of the mounting sleeve 102d is fitted with a rubber inlay ring 102f. The inner wall of the first liquid inlet hole 102b is provided with an inlay groove 102g. The rubber inlay ring 102f is inlaid inside the inlay groove 102g. The bottom of the inner wall of the sampling box 101 is provided with a drainage hole 105. Several drainage holes 105 are provided.

[0047] Specifically, the sampled water enters the sampling chamber 101 through the first inlet hole 102b and the second inlet hole 103e. The water passing through the first inlet hole 102b is filtered through the filter paper 102c and flows into the clear sampling tube 102a, ensuring that the water sample obtained by the clear sampling tube 102a is clear enough. The water entering the sampling chamber 101 through the second inlet hole 103e falls directly into the turbid sampling tube 103a, allowing various microorganisms, algae and plankton in the water to enter the turbid sampling tube 103a, thus enabling the collection of different types of water samples in a single sampling.

[0048] Furthermore, when sampling is required, the user first places the sampling box 101 with the top plate 104 into the water. Water then enters the sampling box 101 through the first inlet port 102b and the second inlet port 103e. The water passing through the first inlet port 102b is filtered through filter paper 102c, blocking suspended particles. The filtered water then flows through the plastic guide bag 102e into the clear sampling tube 102a, ensuring the water sample obtained from the clear sampling tube 102a is sufficiently clear. Meanwhile, the water entering the sampling box 101 through the second inlet port 103e falls directly into the turbid sampling tube 103a, allowing various microorganisms, algae, and plankton present in the water to pass through. The sample can enter the turbid sampling cylinder 103a, and then the sampling box 101 can be pulled up from the water using an external lifting device. Excess water in the sampling box 101 can then be drained directly through the drain hole 105. The water sample directly entering the turbid sampling cylinder 103a contains various microorganisms, algae, and plankton, which are unevenly distributed. After removing the sampling box 101, the waterproof motor 103b is activated, causing the transmission component 103c to rotate. The transmission component 103c then drives the mixing rod 103d to rotate within the turbid sampling cylinder 103a, resulting in a more even distribution of various microorganisms, algae, and oil-bearing organisms. Meanwhile, the transmission component 103d... During the rotation of 03c, the transmission component 103c drives the connecting sleeve 103f-1 to rotate synchronously. Subsequently, the connecting sleeve 103f-1 drives the connected transmission ring 103f-2 to rotate, causing the transmission ring 103f-2 to rotate around the turbid sampling cylinder 103a. This generates centrifugal force on the clear sampling cylinder 102a, separating any remaining impurities inside and causing them to settle to the bottom. When testing with the sampled clear water, only the water in the upper half of the clear sampling cylinder 102a needs to be used, further improving the clarification effect. Meanwhile, the transmission ring 103f-2 drives... When the clear sampling cylinder 102a rotates, the transmission ring 103f-2 will synchronously drive the limiting block 103f-3 to rotate along the inner wall of the limiting groove 103f-4, thereby limiting the rotation path of the transmission ring 103f-2 and ensuring the stability of the movement of the transmission ring 103f-2. After sampling is completed, the top plate 104 can be removed to expose the clear sampling cylinder 102a and the turbid sampling cylinder 103a, making it convenient for users to extract and test. At the same time, when it is necessary to remove the mounting ring, the user can directly press and push the mounting sleeve 102d to make the mounting sleeve 102d drive the inlay ring to disengage from the inlay groove 102g. Then the user can remove and replace the mounting sleeve 102d and the filter paper 102c.

[0049] It should be noted that the filter paper 102c has a pore size of 0.45μm. This pore size design effectively traps suspended particulate matter in the water (such as silt, algae, and microbial residues), while allowing dissolved ions, small organic molecules, and inorganic matter to pass through. This process eliminates the interference of suspended solids on subsequent physicochemical analyses (such as heavy metals, nutrients, and organic matter), ensuring that the test results reflect the true dissolved composition of the water.

[0050] Example 3

[0051] Reference Figures 1-6 In the third embodiment of the present invention, a cleaning mechanism 200 is provided to perform auxiliary cleaning of the filter and ensure sampling efficiency.

[0052] A cleaning mechanism 200 is fixedly connected to the top of the sampling box 101. The cleaning mechanism 200 includes a support frame 201. Three support frames 201 are arranged in a ring and are evenly distributed. A transmission sleeve 202 is provided on the top of the sampling box 101. An impeller 203 is movably connected to the bottom of the inner wall of the transmission sleeve 202. A transmission frame 204 is fixedly connected to the bottom of the impeller 203. The bottom of the transmission frame 204 extends through to the bottom of the transmission sleeve 202 and is movably connected to the transmission sleeve 202. Scraper strips 205 are fixedly connected to both sides of the bottom of the transmission frame 204. A gathering cover 206 is fixedly connected to the top of the transmission sleeve 202. The diameter of the bottom of the gathering cover 206 is smaller than the diameter of the top. A guide strip 207 is fixedly connected to the bottom of the transmission sleeve 202. Several guide strips 207 are arranged in a ring and are evenly distributed. The guide strips 207 are inclined inward from the top to the bottom.

[0053] Specifically, when the user uses an external lifting device to pull the collection box out of the water, the collection box will drive the support frame 201, the transmission sleeve 202 on the support frame 201, and the impeller 203 to move upward. When moving in the water, the movement of the water flow relative to the impeller 203 will generate lift and resistance difference due to the asymmetrical shape of the blades on the surface of the impeller 203, forming a torque, thereby driving the impeller 203 to rotate and drive the scraper 205 to scrape the top of the filter paper 102c, thereby assisting the filter paper 102c in cleaning. This avoids excessive filter material on the top of the filter paper 102c in water with more impurities, which would affect the filtration efficiency of the filter paper 102c. At the same time, the rotation of the impeller 203 will also cause the water flowing through the impeller 203 to generate a certain impact force on the filter paper 102c. The power of the water flow can also wash away the filter material on the filter paper 102c. The scraping of the scraper 205 further improves the cleaning effect.

[0054] Furthermore, when the user uses an external lifting device to pull the collection box out of the water, the collection box will drive the support frame 201, the transmission sleeve 202 on the support frame 201, and the impeller 203 to move upward. When moving in the water, the water flow relative to the impeller 203 will generate lift and resistance due to the asymmetrical shape of the blades on the surface of the impeller 203, forming a torque, thereby driving the impeller 203 to rotate. Then, the impeller 203 will drive the transmission frame 204 to rotate, causing the transmission frame 204 to drive the scraper 205 to scrape the top of the filter paper 102c, thereby assisting in cleaning the filter paper 102c and preventing excessive filter material on the top of the filter paper 102c from affecting the filtration efficiency in water with more impurities. At the same time, the rotation of the impeller 203 will also cause the water flowing through the impeller 203 to affect the filter paper 102c. The water generates a certain impact force, and the power of the water flow can also break up the filtered material on the filter paper 102c. At the same time, the scraping action of the scraper 205 further improves the cleaning effect. As the impeller 203 moves in the water, the water flows through the interior of the collecting hood 206. Since the diameter of the bottom of the collecting hood 206 is smaller than the diameter of the top, the driving force of the water flow on the impeller 203 is increased, thereby increasing the rotation speed of the scraper 205 and ensuring cleaning efficiency. At the same time, as the water flows through the impeller 203 and impacts the filter paper 102c, the multiple guide strips 207, which are inclined inward from the top to the bottom, can guide the direction of the outflowing water, making the water flow closer to the position of the filter paper 102c, ensuring a better cleaning effect on the filter paper 102c.

[0055] It should be noted that the impeller 203 is made of lightweight plastic, which makes the impeller 203 more efficient in driving and ensures rotational power.

[0056] The remaining structure is the same as that in Example 2.

[0057] Example 4

[0058] Reference Figures 1-6 This is the fourth embodiment of the present invention, which differs from the third embodiment in that: this embodiment provides a water source sampling device and sampling method for water ecological environment monitoring.

[0059] When sampling is required, the user first places the sampling box 101 with its top plate 104 into the water. Water then enters the sampling box 101 through the first inlet port 102b and the second inlet port 103e. Water passing through the first inlet port 102b is filtered through filter paper 102c, blocking suspended particles. The filtered water then flows through the plastic guide bag 102e into the clear sampling tube 102a, ensuring the water sample obtained from the clear sampling tube 102a is sufficiently clear. Water entering the sampling box 101 through the second inlet port 103e falls directly into the turbid sampling tube 103a, allowing various microorganisms, algae, and plankton present in the water to pass through. The sample is placed into the turbid sampling cylinder 103a. Then, an external lifting device can be used to pull the sampling box 101 out of the water. Excess water in the sampling box 101 can be drained directly through the drain hole 105. The water sample entering the turbid sampling cylinder 103a contains various microorganisms, algae, and plankton, which are unevenly distributed. After removing the sampling box 101, the waterproof motor 103b is activated, causing the transmission component 103c to rotate. The transmission component 103c then drives the mixing rod 103d to rotate within the turbid sampling cylinder 103a, resulting in a more even distribution of various microorganisms, algae, and oil-bearing organisms. Meanwhile, the transmission component 103c... During rotation, the transmission component 103c drives the connecting sleeve 103f-1 to rotate synchronously. The connecting sleeve 103f-1 then drives the connected transmission ring 103f-2 to rotate, causing the transmission ring 103f-2 to rotate around the turbid sampling cylinder 103a. This generates centrifugal force on the clear sampling cylinder 102a, separating any remaining impurities inside and causing them to settle to the bottom. When testing with the sampled clear water, only the water in the upper half of the clear sampling cylinder 102a needs to be used, further improving the clarification effect. When the sampling cylinder 102a rotates, the transmission ring 103f-2 will synchronously drive the limiting block 103f-3 to rotate along the inner wall of the limiting groove 103f-4, thereby limiting the rotation path of the transmission ring 103f-2 and ensuring the stability of the movement of the transmission ring 103f-2. After sampling is completed, the top plate 104 can be removed to expose the clear sampling cylinder 102a and the turbid sampling cylinder 103a, making it convenient for users to extract and test. At the same time, when it is necessary to remove the mounting ring, the user can directly press and push the mounting sleeve 102d to make the mounting sleeve 102d drive the inlay ring to disengage from the inlay groove 102g. Then the user can remove and replace the mounting sleeve 102d and the filter paper 102c.

[0060] When the user uses an external lifting device to pull the collection box out of the water, the collection box will drive the support frame 201, the transmission sleeve 202 on the support frame 201, and the impeller 203 to move upward. During this movement in the water, the water flow relative to the impeller 203 will generate lift and resistance due to the asymmetrical shape of the blades on the impeller 203's surface, creating a torque that drives the impeller 203 to rotate. The impeller 203 then drives the transmission frame 204 to rotate, causing the transmission frame 204 to drive the scraper 205 to scrape the top of the filter paper 102c, thus assisting in cleaning the filter paper 102c. This prevents excessive filter material from remaining on the top of the filter paper 102c in water with high levels of impurities, which could affect the filtration efficiency of the filter paper 102c. Simultaneously, the rotation of the impeller 203 will also cause the water flowing over the impeller 203 to exert a force on the filter paper 102c... The water's impact force, combined with the power of the water flow, can dislodge the filtered material on the filter paper 102c. The scraping action of the scraper 205 further enhances the cleaning effect. As the impeller 203 moves in the water, the water flows through the interior of the collecting hood 206. Because the bottom diameter of the collecting hood 206 is smaller than its top diameter, the driving force of the water flow on the impeller 203 is increased, thereby increasing the rotational speed of the scraper 205 and ensuring cleaning efficiency. Simultaneously, as the water flows past the impeller 203 and impacts the filter paper 102c, multiple guide strips 207, angled inwards from top to bottom, guide the outflow of water, bringing it closer to the filter paper 102c and ensuring a better cleaning effect.

[0061] In summary, when the sampling device 100 is placed in water, the clear sampling component 102 can filter and obtain a clear water sample, while the turbid sampling component 103 can directly contact and obtain a turbid water sample. At the same time, when the sampling device 100 is retrieved, the cleaning mechanism 200 will be activated to clean the filter of the clear sampling component 102, thereby avoiding clogging of the filter.
