Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring technology, specifically a sampling device for monitoring environmental wastewater. Background Technology

[0002] In the field of environmental monitoring, accurate and effective sampling of wastewater is the foundation for obtaining reliable monitoring data. With the acceleration of industrialization and urbanization, the discharge of various types of wastewater is becoming increasingly complex, which brings many challenges to wastewater sampling work. Existing sampling devices have a series of problems that cannot be ignored.

[0003] Regarding clogging by impurities, traditional environmental wastewater sampling devices show significant shortcomings when dealing with wastewater containing a large amount of impurities. Most devices rely solely on simple filters, lacking effective anti-clogging and cleaning mechanisms. When wastewater contains large particulate impurities, such as sand and gravel in construction wastewater or metal fragments in industrial wastewater, these impurities easily accumulate on the filter surface, quickly clogging the filter pores and preventing water samples from entering the sampling device, leading to sampling interruptions. Even if some devices are equipped with cleaning components, they often use a single cleaning method, which cannot cope with complex and diverse impurities, resulting in poor cleaning effects. Moreover, once the filter is clogged, manual cleaning is time-consuming and laborious, seriously affecting sampling efficiency. If it is not cleaned in time, the collected water samples will lose their representativeness, leading to deviations in monitoring data.

[0004] In terms of ease of sampling operation, traditional sampling equipment has a relatively cumbersome operating procedure. Taking the common manual pump sampler as an example, the operator needs to repeatedly press the pump body manually to draw water samples. When large-scale or continuous sampling is required, this not only consumes a lot of the operator's physical strength, but also results in slow operation and low efficiency. At the same time, this manual operation method makes it difficult to ensure the consistency and accuracy of each sampling, and is easily affected by the operator's subjective factors. For example, different pressing pressure may lead to differences in the sampling volume, which in turn affects the reliability of the monitoring results. Therefore, there is an urgent need to improve a sampling device for environmental wastewater monitoring to solve the above problems. Utility Model Content

[0014] 1. This sampling device for environmental wastewater monitoring, through its anti-clogging mechanism design, uses a fan blade driven by the water flow to rotate the shaft, which in turn drives the scraper to clean impurities from the surface of the filter plate. Simultaneously, the guide groove design, in conjunction with the slider, guides the mounting base plate to move up and down, allowing the top to clean the filter holes. This multi-component collaborative cleaning method can effectively handle different types of impurities, greatly improves the anti-clogging performance of the filter plate, ensures a continuous and stable water flow during sampling, and guarantees the continuity and efficiency of sampling.

This sampling device for environmental wastewater monitoring, through the design of the sampling mechanism and locking mechanism, uses the buoyancy of the float in the water to drive the rope to move, causing the locking rod to disengage from the locking hole.

At the same time, the rope length can be adjusted according to the sampling depth. With the buoyancy of the float and the assistance of rollers, discs and other components, the depth of the sampling bucket in the water can be controlled more accurately to meet different monitoring needs.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1:

[0025] Based on existing technology, traditional environmental wastewater sampling devices exhibit significant shortcomings when dealing with wastewater containing large amounts of impurities. Most devices rely solely on simple filters, lacking effective anti-clogging and cleaning mechanisms. When wastewater contains large particulate impurities, such as sand and gravel in construction wastewater or metal fragments in industrial wastewater, these impurities easily accumulate on the filter surface, quickly clogging the pores and preventing water samples from entering the sampling device, leading to sampling interruptions. Even if some devices are equipped with cleaning components, they often use a single cleaning method, unable to handle complex and diverse impurities, resulting in poor cleaning effectiveness. Moreover, once the filter is clogged, manual cleaning is time-consuming and labor-intensive, severely impacting sampling efficiency. Failure to clean in a timely manner can also render the collected water samples unrepresentative, leading to biased monitoring data. Therefore, this device is equipped with an anti-clogging mechanism. Please refer to [link / reference needed]. Figures 1-4 This utility model provides a technical solution: a sampling device for environmental wastewater monitoring, comprising a sampling bucket 1, characterized in that: a mounting frame 2 is fixedly installed at the upper end of the sampling bucket 1, a pressing rod 5 is movably installed at the middle position of the mounting frame 2, a piston disc 6 is fixedly installed at the lower end of the pressing rod 5, a sampling port 7 is provided at the middle position of the bottom of the sampling bucket 1, a rubber pad 9 is movably installed on the sampling port 7, and the upper edge of the sampling port 7 is fixedly installed on one side of the rubber pad 9 by screws; the sampling device for environmental wastewater monitoring includes an anti-blocking mechanism, a sampling mechanism, and a locking mechanism, the anti-blocking mechanism includes the sampling bucket 1 and the sampling port 7, a mounting frame 201 is fixedly installed inside the sampling port 7, and a rotating shaft 202 is movably installed inside the mounting frame 201 via a bearing.

[0026] A fan blade 203 is fixedly installed at the upper end of the rotating shaft 202, and a scraper 206 is fixedly installed at the lower end of the rotating shaft 202. A filter plate 207 is fixedly installed at the bottom of the sampling barrel 1 by screws. The filter plate 207 is provided with multiple sets of filter holes 208. The scraper 206 is close to the filter plate 207, but does not contact it.

[0027] The rotating shaft 202 is provided with a reciprocating guide groove 212, and a slider 211 is movably installed in the guide groove 212. The slider 211 is located in the mounting base plate 204. Multiple sets of ejector pins 205 are fixedly installed under the mounting base plate 204. The ejector pins 205 correspond one-to-one with the filter holes 208. The sampling port 7 is provided with a limiting groove 209, and the two sides of the mounting base plate 204 are provided with limiting blocks 210 that cooperate with it.

[0028] When wastewater is introduced into the sampling device, the water flow impacts the fan blades 203, which are fixedly installed on the upper end of the rotating shaft 202, thereby driving the rotating shaft 202 to rotate. The scraper 206 at the lower end of the rotating shaft 202 rotates accordingly, cleaning the impurities on the surface of the filter plate 207 fixedly installed at the bottom of the sampling barrel 1. At the same time, the slider 211, which is movably installed in the reciprocating guide groove 212 on the rotating shaft 202, moves within the guide groove 212 as the rotating shaft 202 rotates. The slider 211 is located within the mounting base plate 204, thereby driving... The mounting base plate 204 moves up and down. Multiple sets of ejector pins 205 fixedly installed under the mounting base plate 204 correspond one-to-one with the filter holes 208 on the filter plate 207. When the mounting base plate 204 moves, the ejector pins 205 clean the filter holes 208. The sampling port 7 is provided with a limiting groove 209. The limiting blocks 210 on both sides of the mounting base plate 204 slide in the limiting groove 209 to ensure that the mounting base plate 204 moves up and down stably, effectively preventing impurities from clogging the filter plate 207 and ensuring that the water sample continuously and stably enters the sampling bucket 1.

[0029] Example 2:

[0030] Building upon Example 1, the operation of traditional sampling equipment is quite cumbersome. Taking a common manual pump sampler as an example, operators need to repeatedly press the pump body manually to extract water samples. This not only consumes a significant amount of the operator's physical strength when large-scale or continuous sampling is required, but also results in slow operation and low efficiency. Furthermore, this manual operation method makes it difficult to guarantee the consistency and accuracy of each sample, and is easily affected by the operator's subjective factors. For example, different pressing pressure may lead to differences in the sample volume, thus affecting the reliability of the monitoring results. Therefore, this device is equipped with a sampling mechanism and a locking mechanism. Please refer to [link / reference]. Figures 1-6This utility model provides a technical solution: a sampling device for monitoring environmental wastewater. The sampling mechanism includes a pressing rod 5, a pressing plate 302 fixedly installed at the top of the pressing rod 5, a piston plate 6 fixedly installed at the bottom of the pressing rod 5, an exhaust port 303 provided on the piston plate 6, a rubber pad 8 movably installed on the exhaust port 303, one side of the rubber pad 8 being fixedly installed at the upper edge of the exhaust port 303 by screws, and a spring 304 fixedly installed between the piston plate 6 and the mounting bracket 2.

[0031] The locking mechanism includes a mounting bracket 2 and a pressing rod 5. The pressing rod 5 is provided with a locking hole 301, and the mounting bracket 2 is provided with connectors 305 for hanging ropes on both sides.

[0032] Mounting frame 1 2 has mounting slot 1 306. A roller 307 is movably mounted in mounting slot 1 306 via a fixed shaft. Next to mounting slot 1 306 is mounting slot 2 309. A disc 308 is movably mounted in mounting slot 2 309. A rope 4 is fixedly mounted on one side of disc 308. The rope 4 passes around mounting slot 1 306 and through mounting frame 1 2. A float 3 is fixedly mounted at its end. The length of the rope 4 can be adjusted later according to the sampling depth.

[0033] A spring 310 is fixedly installed between the disc 308 and the side wall of the mounting groove 309. A locking rod 311 is fixedly installed on the other side of the disc 308. A lever 312 is fixedly installed on the locking rod 311. A sliding groove 313 is provided on the mounting bracket 2. The lever 312 is movably installed in the sliding groove 313. The locking rod 311 can be inserted into the locking hole 301.

[0034] Before sampling, adjust the length of rope 4 according to the required sampling depth. After placing the device in the water, the float 3 floats upward due to the buoyancy of the water, which drives the rope 4, which is fixedly connected to it, to move. Rope 4 passes around the roller 307 in the first mounting groove 306 and is fixedly connected to the disc 308 in the second mounting groove 309, thereby pulling the disc 308 to move backward. The movement of the disc 308 drives the locking rod 311 to move backward, so that the locking rod 311 disengages from the locking hole 301. At this time, the piston disc 6 returns to its original position under the action of the first spring 304, so that a negative pressure is formed in the sampling bucket 1. Under the action of the negative pressure, the wastewater enters the sampling bucket 1 from the sampling port 7 through the filter plate 207, completing the water sample extraction. When the next sampling is required, press the pressing plate 302 to move the pressing rod 5 down. At this time, the locking rod 311 is pushed out under the action of the second spring 310, so that it is locked in the locking hole 301, which facilitates the next sampling.
