Description

Technical Field

[0001] This invention belongs to the field of wastewater sampling technology, specifically a water sampling device for tracing the source of industrial wastewater. Background Technology

[0002] With the acceleration of industrialization, the discharge of industrial wastewater has been increasing year by year. Its complex composition and strong polluting properties have made it one of the main sources of water pollution. Accurately tracing the source of industrial wastewater discharge is a key prerequisite for pollution control and environmental supervision. Water sampling, as the core link of wastewater source tracing, requires the deployment of sampling equipment in different water areas to collect representative water samples. This provides reliable data support for subsequent water quality testing, pollutant fingerprint comparison, and pollution source location, and directly determines the accuracy and timeliness of the source tracing results.

[0003] To improve sampling and source tracing efficiency, existing industrial wastewater source tracing sampling devices generally adopt a timed sampling and online detection mode, which eliminates the need for frequent manual intervention and enables continuous sampling and monitoring of multiple water areas over long periods, significantly reducing manpower input and adapting to the source tracing needs of complex scenarios such as industrial parks and municipal pipe networks. However, this mode still has significant technical pain points in practical applications, seriously affecting the reliability of detection data and restricting the improvement of source tracing accuracy.

[0004] After each sampling, the inner wall of the pipe will be covered with the wastewater residue from the previous sampling. Due to the lack of an effective cleaning mechanism, the residual water sample cannot be completely discharged. When the next sampling is carried out, the newly collected water sample will mix with the residual water sample in the pipe, causing the water sample composition to be diluted or contaminated, destroying the original characteristics of the water sample, making the test data unable to truly reflect the water quality of the current sampling area, and interfering with the judgment of the type and concentration of pollutants.

[0005] As a core component in the detection process, the water quality sensor's sensor head directly contacts the water sample to capture key parameters such as pH, residual chlorine, and pollutant concentration. Its performance stability directly determines the reliability of the detection results. During timed sampling, pollutants remaining after the previous detection will adhere to the surface of the sensor head, forming dirt or biofilm. This not only obstructs the sensing element and weakens the detection signal, but may also react chemically with subsequent water samples, causing the sensor to respond slowly and the values ​​to drift, further aggravating the detection error and making it difficult to meet the stringent requirements for detection accuracy in industrial wastewater source tracing.

[0006] Therefore, the present invention provides a water sampling device for tracing the source of industrial wastewater. Summary of the Invention

This ensures that the sensing components are always clean and sensitive, effectively preventing issues such as signal drift and response lag. Simultaneously, the return pipe and storage cylinder, in conjunction with a bidirectional pump, flush the entire flow path with clean water before the next sampling, thoroughly draining any residual wastewater from the pipes. This prevents the mixing of old and new water samples from causing dilution or cross-contamination, ensuring that each collected water sample accurately reflects the current water quality characteristics.

[0016] 2. This invention, by incorporating a flow guide tube, a scraper, and a storage cylinder, achieves the self-regeneration and long-term stable operation of the cleaning components. It utilizes a combination of backflushing and scraping to perform dual cleaning of the wiping layer, flushing away adsorbed contaminants from the inside out and mechanically scraping away surface liquid and impurities. This maintains the wiping layer's good absorbency and cleaning ability, preventing overall effectiveness from being reduced due to contamination of the cleaning components themselves. Simultaneously, the flow guide tube and storage cylinder enable temporary storage and quantitative supply of cleaning water, ensuring a high degree of coordination between water supply and cleaning actions. Multiple automatic cleaning cycles can be completed without frequent manual water replenishment. The overall structure achieves full automation of sampling, detection, sensor cleaning, and self-cleaning of the cleaning tools, significantly improving the device's continuous working capacity and service life, reducing maintenance costs, and making it more suitable for unattended scenarios such as industrial parks and remote water areas.

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] like Figures 1 to 9 As shown, the water sampling device for tracing the source of industrial wastewater according to the present invention includes an installation part, a sampling mechanism, a detection mechanism, a wiping mechanism, and a reflux mechanism.

[0022] The installation unit includes a buoyancy disk 1 and an installation box 2. The buoyancy disk 1 is fixedly installed on the upper surface of the installation box 2. The density of the buoyancy disk 1 is not higher than the density of the water body in the water area to be sampled. During sampling, the buoyancy disk 1 is first placed in the target water area. Inside the buoyancy disk 1, there is a battery and an information interaction component (not shown in the figure). The information of the test sample is transmitted to the background through the information interaction component.

[0023] The sampling mechanism includes a control pump 13, a feed pipe 16, and a filter 12. The control pump 13 is fixedly installed inside the buoyancy plate 1. The filter 12 is connected to the input end of the control pump 13. During sampling, the filter 12 is located in the water body. When the control pump 13 extracts the sample, solid impurities are filtered through the filter 12.

[0024] The feed pipe 16 is connected to the output end of the control pump 13. During sampling, the sample extracted by the control pump 13 is discharged through the feed pipe 16. The control pump 13 is a common bidirectional micro water pump, and its input and output directions can be adjusted.

[0025] The testing mechanism includes a stage 10 and a sensing plate 9. The sensing plate 9 is used to test the sample. In this embodiment, the sensing plate 9 is a common acid-base detection sensor.

[0026] The induction plate 9 is installed at an angle on the outer wall of the platform 10, and the platform 10 is fixedly installed on the inner wall of the buoyancy plate 1. The feed pipe 16 is located above the platform 10. After the control pump 13 draws water samples, they are discharged through the feed pipe 16 and flow along the platform 10. At this time, the induction plate 9 detects the sample and then feeds the detection results back to the background as the data basis for wastewater source tracing.

[0027] The wiping mechanism includes a slider 20 and a wiping layer 21. The slider 20 is slidably disposed on the outer wall of the platform 10, and the wiping layer 21 is elastically disposed at the bottom of the slider 20. The slider 20 is slidably adjusted to drive the wiping layer 21 to slide synchronously. The elastic force on the wiping layer 21 causes the wiping layer 21 to tend to adhere to the sensing plate 9.

[0028] During operation, the device is first deployed to the target water area via the buoyancy plate 1 of the mounting unit. Since the density of the buoyancy plate 1 is not higher than the density of the water in the sampling area, the device can float stably. The battery inside the buoyancy plate 1 powers all mechanisms, and the information interaction component transmits detection information to the backend. During the sampling phase, the control pump 13 of the collection mechanism is activated to extract water samples. The samples first pass through the filter 12 connected to the input of the control pump 13 to filter solid impurities, and then are discharged through the feed pipe 16 at the output of the control pump 13. During the detection phase, the water sample discharged from the feed pipe 16 flows along the platform 10 fixed to the inner wall of the buoyancy plate 1. The induction plate 9, tilted and installed on the outer wall of the platform 10, detects the water sample parameters in real time. The detection results are fed back to the backend via the information interaction component, serving as the data basis for wastewater source tracing. After detection, the sliding slider 20 is slidable, causing the wiping layer 21, elastically set at the bottom of the slider 20, to slide synchronously. Because the wiping layer 21 is always under elastic force and tends to adhere to the induction plate 9, it can wipe away residual contaminants on the surface of the induction plate 9, completing the cleaning process and avoiding affecting the accuracy of the next detection.

[0029] The reflux mechanism includes a storage cylinder 15 and a reflux pipe 14. The storage cylinder 15 is fixedly installed on the inner wall of the buoyancy plate 1, and the inner cavity of the storage cylinder 15 is used to store clean water.

[0030] The storage cylinder 15 and the output end of the control pump 13 are connected by a return pipe 14. One end of the return pipe 14 extends into the inner cavity of the storage cylinder 15. When the next sampling is required, the input and output directions of the control pump 13 are first adjusted, and then the clean water in the storage cylinder 15 is drawn through the return pipe 14. Then the clean water is discharged from the filter 12.

[0031] This measure thoroughly removes residual wastewater from the previous sampling from the pipeline, preventing contamination or dilution caused by mixing of residual water samples with newly collected water samples. This ensures that the original characteristics of the new water samples are not disturbed. At the same time, rinsing with clean water reduces the adhesion of pollutants to the inner wall of the pipeline, lowering the probability of pollutants coming into contact with and contaminating the sensing plate 9 through the water flow. Combined with the cleaning of the sensing plate 9 by the wiping mechanism, this further improves the accuracy of subsequent detection data, providing a more reliable sampling and detection basis for tracing the source of industrial wastewater. It also reduces the accumulation of dirt in the pipeline, extends the service life of components such as the control pump 13 and the filter 12, and ensures the long-term stable operation of the device.

[0032] The bottom surface of the buoyancy disk 1 is connected to a counterweight anchor block 4 by a traction rope. Multiple counterweight anchor blocks 4 are evenly arranged in a ring along the axis of the buoyancy disk 1. After the buoyancy disk 1 is deployed, the counterweight anchor blocks 4 sink to the bottom of the water, thereby fixing the position of the buoyancy disk 1.

[0033] A photovoltaic panel 3 is fixedly installed on the upper surface of the mounting box 2. The photovoltaic panel 3 is tilted and is used to convert light energy into electrical energy, thereby providing power to the electronic components in the equipment, and can also charge the battery.

[0034] An air duct 8 is fixedly installed on the inner wall of the mounting box 2. The air duct 8 is a square tube with an opening at the bottom. A through hole communicating with the inner cavity of the storage cylinder 15 is opened at the bottom of the mounting box 2, and the opening at the bottom of the air duct 8 faces the through hole.

[0035] A duct fan 5 is fixedly installed at one end of the air duct 8, a heat exchange plate 7 is fixedly installed on the inner wall of the air duct 8, and a control plate 6 is fixedly installed on the outer wall of the air duct 8. The control plate 6 is a common semiconductor refrigeration plate with a cold end and a hot end.

[0036] Multiple heat exchange plates 7 are evenly arranged along the cold end of the control plate 6. The heat exchange plates 7 are made of copper plates. Moisture on the surface of the water is drawn out by the duct fan 5. Then the humid air comes into contact with the low temperature heat exchange plates 7. The moisture condenses into water droplets when it encounters the cold air and finally drips into the inside of the storage cylinder 15, thereby replenishing the liquid in the inner cavity of the storage cylinder 15.

[0037] In a preferred embodiment of the present invention, a guide rod 19 is fixedly installed on the side wall of the platform 10. The guide rod 19 is a smooth rod that passes through the slider 20 and is slidably connected to the slider 20. By setting the guide rod 19, the sliding stability of the slider 20 can be effectively improved.

[0038] A control screw 37 is rotatably mounted on the side wall of the stage 10. The control screw 37 passes through the slider 20 and is connected to the slider 20 through internal and external thread engagement. Rotating the control screw 37 causes the slider 20 to slide, thereby causing the wiping layer 21 to slide, which is used to wipe and clean the sensor plate 9 after detection.

[0039] A control motor 17 is fixedly installed on the side wall of the platform 10. The output shaft of the control motor 17 is connected to the control screw 37 through a transmission component. The transmission component is a common belt and pulley. The control motor 17 drives the control screw 37 to rotate, thereby controlling the slider 20 to slide.

[0040] A support plate 18 is fixedly installed on the bottom surface of the slider 20, and a guide pipe 25 is fixedly installed on the inner wall of the support plate 18. The guide pipe 25 is made of common hard copper pipe.

[0041] One end of the guide tube 25 passes through the support plate 18 and is fixedly mounted on the mounting plate 24. The bottom surface of the mounting plate 24 is fixedly connected to the outer wall of the wiping layer 21. A spring is installed on the outer wall of the support plate 18, and the other end of the spring is connected to the outer wall of the mounting plate 24. The spring force pushes the mounting plate 24 to achieve the sliding connection between the wiping layer 21 and the slider 20. The guide tube 25 is provided to improve the stability of the sliding between the mounting plate 24 and the wiping layer 21.

[0042] The wiping layer 21 is made of elastic material. The bottom surface of the mounting plate 24 is provided with a guide groove 36. The guide groove 36 is connected to the inner cavity of the guide pipe 25. By introducing clean water from the storage cylinder 15 into the guide pipe 25 and then discharging it through the guide groove 36, the clean water is finally discharged through the wiping layer 21, thus achieving backwash cleaning of the wiping layer 21 from the inside out.

[0043] A mounting bracket 26 is fixedly installed on the outer wall of the platform 10, and a scraper 27 is elastically installed on the outer wall of the mounting bracket 26. The scraper 27 is tilted appropriately.

[0044] After the sliding adjustment slider 20 wipes the wiping layer 21 and wipes the sensing plate 9, it continues to slide towards the side of the platform 10. At this time, the wiping layer 21 pushes the scraper 27 to deflect. When the wiping layer 21 passes the scraper 27, the scraper 27 is lifted by the elastic force. At this time, the wiping layer 21 slides in the opposite direction and the scraper 27 scrapes the surface of the wiping layer 21 to clean the wiping layer 21 and discharge the adsorbed liquid, thus achieving the scraping and cleaning of the wiping layer 21.

[0045] In a preferred embodiment of the present invention, a connecting plate 23 is fixedly installed on the inner wall of the platform 10. The outer wall of the connecting plate 23 is provided with a groove for the guide tube 25 to be inserted. After the wiping layer 21 wipes and cleans the sensor plate 9 and passes the scraper plate 27, the adjusting slider 20 continues to slide until the guide tube 25 is inserted into the groove of the connecting plate 23.

[0046] The upper end of the connecting plate 23 is provided with a transfer cylinder 11, which is used to transfer the clean water inside the storage cylinder 15.

[0047] A support frame 28 is fixedly installed on the inner wall of the transfer cylinder 11, and a control plug 29 is slidably installed on the inner wall of the transfer cylinder 11. The upper end face of the control plug 29 is connected to the outer wall of the support frame 28 through an elastic element. After the guide pipe 25 is inserted into the connecting plate 23, the control connecting plate 23 is opened. At this time, the control plug 29 is elastically slid downward to discharge the clean water inside. The clean water enters the inner cavity of the guide groove 36 through the guide pipe 25 to provide clean water for the backwash cleaning of the wiping layer 21.

[0048] A connecting pipe 30 is rotatably mounted on the upper end face of the connecting plate 23. A sealed bearing and a torsion spring are provided at the connection position between the connecting pipe 30 and the connecting plate 23. When the connecting pipe 30 rotates, the sealing bearing maintains the seal between the two. After rotation, the spring force of the torsion spring controls the connecting pipe 30 to return to its original position.

[0049] The inner cavity of the transfer tube 30 is connected to the inner cavity of the transfer cylinder 11. The connection between the connecting plate 23 and the inner cavity of the transfer cylinder 11 is achieved through the transfer tube 30. When the transfer cylinder 11 is draining liquid, the liquid enters the inner cavity of the guide tube 25 through the transfer tube 30.

[0050] A control shaft 31 is fixedly installed on the inner wall of the connecting plate 23, and a partition plate 32 is fixedly installed on the inner wall of the adapter pipe 30. A fan-shaped through hole is opened on the outer wall of the partition plate 32. The control shaft 31 passes through the partition plate 32 and a sealing plate 34 is fixedly installed thereon. The sealing plate 34 is used to close the fan-shaped through hole. Rotating the adapter pipe 30 drives the partition plate 32 to rotate. When the fan-shaped through hole is open, the adapter pipe 30 is open. Then, the torsion spring controls the adapter pipe 30 to reset. At this time, the sealing plate 34 closes the fan-shaped through hole, thereby realizing the closure of the adapter pipe 30.

[0051] An adjusting plate 33 is elastically installed on the inner wall of the connecting plate 23. A connecting rope is wound around the radial outer wall of the adapter pipe 30. The outer wall of the adjusting plate 33 is fixedly connected to the other end of the connecting rope. During the process of inserting the guide pipe 25 into the connecting plate 23, the adjusting plate 33 is pushed to slide. When the adjusting plate 33 slides, the adapter pipe 30 is pulled to rotate through the connecting rope until the guide pipe 25 is directly below the adapter pipe 30. At this time, the fan-shaped through hole of the partition plate 32 is fully open to facilitate the input of clean water into the guide pipe 25. After the guide pipe 25 is separated from the connecting plate 23, the adjusting plate 33 is reset. At this time, the adapter pipe 30 is reset by the elastic force of the torsion spring until the fan-shaped through hole of the partition plate 32 is closed.

[0052] A guide tube 22 is fixedly installed on the outer wall of the guide rod 19. An adjusting plug 38 is elastically installed in the inner cavity of the guide tube 22. A force ring 35 is fixedly installed on the axial end of the adjusting plug 38. When the slider 20 slides, it first contacts the force ring 35 and presses against the force ring 35. After the force ring 35 slides a certain distance, the guide tube 25 enters the inner cavity of the connecting plate 23.

[0053] The outer wall of the guide tube 22 is provided with an inlet pipe and an outlet pipe. Both the inlet pipe and the outlet pipe are unidirectional and have opposite directions of conduction. A one-way valve is provided in the inner cavity of both the outlet pipe and the inlet pipe of the guide tube 22.

[0054] The inlet pipe of the guide tube 22 is connected to the inner cavity of the storage tube 15, and the outlet pipe of the guide tube 22 is connected to the inner cavity of the transfer tube 11. When the guide tube 25 has not entered the interior of the connecting plate 23, the slider 20 is controlled to reciprocate to press the force ring 35, thereby controlling the adjusting plug 38 to reciprocate to slide, thereby drawing clean water from the inner cavity of the storage tube 15 into the interior of the transfer tube 11, so that clean water can be output after the guide tube 25 and the connecting plate 23 are connected.

[0055] After wiping and cleaning the sensor plate 9, the slider 20 reciprocates to push the force ring 35, causing the adjusting plug 38 to slide back and forth. The input pipe of the guide tube 22 draws clean water from the storage tube 15, and then the clean water is input into the transfer tube 11 through the output pipe until the control plug 29 moves to the highest position. Then, the slider 20 is controlled to slide until the guide tube 25 is inserted into the groove of the connecting plate 23. The guide tube 25 pushes the adjusting plate 33 to slide, and the connecting rope pulls the transfer tube 30 to rotate, so that the fan-shaped through hole of the partition plate 32 is misaligned and connected with the closed plate 34. The control plug 29 in the transfer tube 11 slides downward under the action of the elastic element, and sends clean water into the guide tube 25 through the transfer tube 30. The clean water flows into the guide groove 36 of the mounting plate 24 through the guide tube 25, and finally flows out from the inside to the outside through the wiping layer 21 made of elastic material, realizing the backwash cleaning of the wiping layer 21.

[0056] After backflushing and cleaning, the control motor 17 drives the control screw 37 to rotate via the belt and pulley, causing the slider 20 to slide along the guide rod 19. The slider 20 scrapes the surface of the wiping layer 21 through the scraper plate 27, discharging the liquid and contaminants it has absorbed, thus completing the scraping and cleaning of the wiping layer 21.
