Description

Technical Field

[0001] The present invention belongs to the field of soil pollution control, and in particular relates to a sampling auxiliary device for soil pollution prevention and treatment and an operating method thereof. Background Art

[0002] Soil monitoring is an important part of environmental monitoring. Its purpose is to determine the background value, monitor, forecast and control the soil environmental quality. The priority monitoring objects of soil pollution should be substances that have a significant impact on human health and maintaining ecological balance, such as elements and inorganic pollutants such as mercury, cadmium, lead, arsenic, and chromium. The determination of soil pollution components such as infectious bacteria and viruses introduced by fecal waste and domestic sewage is a trace analysis and ultra-trace analysis. In addition, due to the particularity of the soil environment, the results of soil monitoring are of great significance for understanding the status of soil environmental quality, implementing soil pollution source prevention and control methods and quality management.

[0003] In existing technologies, soil sampling is mostly carried out by inserting a drill rod into the soil to collect soil samples. However, after the soil sample is taken out of the sampling vessel, it is inconvenient to clean the sampling vessel, resulting in soil sample residue easily remaining in the sampling vessel. When the sampling vessel is used next time, the soil sample remaining inside it is easy to cross-contaminate with the newly taken sample, affecting the accuracy of the soil detection of the newly taken sample. In addition, after the drill rod is inserted into the soil and taken out, its surface will also adhere to the soil. If it is not cleaned in time, when the soil is sampled in layers, the upper layer of soil remaining on the drill rod will fall off when the lower layer sample is collected, resulting in interlayer contamination and misjudgment of geological information.

[0004] To this end, the present invention provides a sampling auxiliary device for soil pollution prevention and control and an operating method thereof. Summary of the Invention

[0023] The beneficial effects of the present invention are as follows:

[0024] 1. The present invention relates to a sampling auxiliary device for soil pollution prevention and control and an operating method thereof. A block is controlled to move out of a slot by an electric telescopic rod. When the block is no longer limited, the slide can slide freely on the drill rod. Thus, a nozzle can be controlled by a first motor to align with the position of a feed trough, facilitating the cleaning of several feed troughs one by one. The nozzle sprays to flush the residual soil in the feed trough. A cover box is provided to protect the outside of the feed trough to prevent water from colliding with the feed trough and splashing to the outside, causing mud diffusion and pollution. The mud water after flushing can be filtered by a filter plate, so that the filtered water is stored in a water storage chamber for reuse.

[0025] 2. The present invention relates to a sampling auxiliary device for soil pollution prevention and control and an operating method thereof. When the nozzle cleans the upper feed trough, the heating chamber is located at the feed trough that has just been flushed below. The external air is pumped into the feed trough along the exhaust pipe by an air pump, and the gas entering the feed trough is heated by the heating wire, thereby allowing the hot air to dry the feed trough. As the gas in the heating chamber flows into the heating chamber, the gas with a pressure greater than the saturation pressure is discharged outward along the connecting pipe. By setting the air outlet pipe to an inclined state, the gas ejected from the cavity is tilted and hits the inclined surface of the filter plate, which is convenient for blowing off the mud on the filter plate and preventing the mud from staying on the filter plate and clogging the filter plate and affecting the filtration.

[0026] 3. The present invention relates to a sampling auxiliary device for soil pollution prevention and control and an operating method thereof. A scraper is attached to the outer wall of a drill rod. When the drill rod is pulled out of the soil, the inclined surface at the bottom of the scraper can scrape off the soil adhering to the drill rod, preventing the soil adhering to the drill rod from affecting subsequent soil sampling. The scraper is continuously vibrated downward by the cooperation of a cam and a second spring, thereby shaking off the soil adhering to the inclined surface at the bottom of the scraper.

[0027] 4. The present invention describes a sampling auxiliary device for soil pollution prevention and control and an operating method thereof. By controlling a plurality of sliders to move laterally and insert into the soil, the soil is sampled in layers. The soil enters the feed trough along the inclined surfaces on one side of the two blocks. When the sliders are controlled to move back and retract into the drill rod, the inclined surfaces on the other side of the two blocks pull the sampled soil away from the ground, thereby preventing the sampled soil from slipping out of the feed trough due to adhesion between the soils.

The output end of the hydraulic cylinder 22 is fixedly connected to a lower pressure plate 23, and the bottom of the lower pressure plate 23 is fixedly connected to a slide rod 16. The inner wall of the drill rod 7 is equidistantly slidably connected to a number of sliders 13. A feed trough 14 is provided inside the slider 13. The bottom of the inner wall of the feed trough 14 is set as an inclined surface. The outer wall of the slide rod 16 is equidistantly connected to a number of connecting shafts 17. The connecting shaft 17 is rotatably connected to the slider 13. The inner wall of the drill rod 7 is located below the slider 13. The square is fixedly connected to a support plate 18, the inner wall of the support plate 18 is fixedly connected to a first sliding shaft 19, the outer wall of the first sliding shaft 19 is slidably connected to a second connecting block 20, the second connecting block 20 is fixedly connected to the slider 13, the outer wall of the first sliding shaft 19 is sleeved with a first spring 21, one end of the first spring 21 is fixedly connected to the support plate 18, and the other end of the first spring 21 is fixedly connected to the second connecting block 20, the inner wall of the feed trough 14 is symmetrically fixedly connected with two blocks 15, and both sides of the block 15 are set as inclined surfaces.

[0041] Through the above technical solution, the electric telescopic rod 9 controls the block 10 to move to the inside of the card slot 11, and the base 1 is moved to the top of the soil sampling. The first motor 3 is started to drive the screw 4 to rotate, so that the first connecting block 5 moves downward, and the slide plate 6 moves downward. The card slot 11 is limited by the block 10. When the slide plate 6 moves downward, it drives the drill rod 7 to move downward, so that the drill rod 7 is inserted into the soil below. The hydraulic cylinder 22 is started to drive the lower pressure plate 23 to move downward, so that the slide rod 16 moves downward. When the slide rod 16 moves downward, it pushes several connecting shafts 17 to move downward and rotate. Under the push of several connecting shafts 17, several sliders 13 are extended outward and inserted into the soil laterally, so that the soil enters the feed Sampling is carried out in the groove 14, and the movement of the slider 13 drives the second connecting block 20 to move, compressing the first spring 21. After the soil enters the feed trough 14 along the inclined surface on one side of the two block blocks 15, the hydraulic cylinder 22 controls the lower pressure plate 23 to move upward. Under the pull of the connecting shaft 17, the slider 13 is retracted into the drill rod 7 in cooperation with the first spring 21. Under the pull of the inclined surface on the other side of the two block blocks 15, the sampled soil is helped to break free from the ground, preventing the sampled soil from slipping out of the feed trough 14 due to mutual adhesion between the soils. Subsequently, the slide plate 6 is controlled to move upward by the first motor 3, driving the drill rod 7 to move upward and out of the ground. By setting the feed trough 14 to an inclined surface, it is convenient to remove the sampled soil.

[0042] Specifically, the flushing component includes a water storage chamber 24, which is opened inside the slide 6. A water inlet 25 is opened on the top of the slide 6. The water inlet 25 is communicated with the water storage chamber 24. A water pump 26 is fixedly connected to the top of the slide 6. The output end of the water pump 26 is connected to a water pumping pipe 27. One end of the water pumping pipe 27 extends to the inside of the water storage chamber 24. The other end of the water pumping pipe 27 is provided with a nozzle 28. The outer wall of the support frame 2 is fixedly connected to the top plate 12 above the limit block 8; the outer wall of the water pumping pipe 27 is fixedly connected to the cover box 2 9. The inner wall of the cover box 29 is set to be semicircular; a filter chamber 31 is opened on the top of the slide 6, and the filter chamber 31 is communicated with the water storage chamber 24. A filter plate 32 is fixedly connected to the top of the slide 6 and located above the filter chamber 31. The top of the filter plate 32 is set to a symmetrical inclined surface. The top of the filter plate 32 is symmetrically fixedly connected to two side plates 33. The top of the slide 6 is fixedly connected to a guide block 30. The guide block 30 fits the outer wall of the drill rod 7. The top of the guide block 30 is set to an inclined surface. The end of the inclined surface of the top of the guide block 30 extends to the top of the filter plate 32.

[0043] Through the above technical solution, water is filled into the water storage chamber 24 through the water inlet 25. After the sampled soil is taken out, the block 10 is controlled to move out of the card slot 11 by the electric telescopic rod 9. When the limit of the block 10 is lost, the slide 6 can slide freely on the drill rod 7. At this time, the slide 6 is first controlled by the first motor 3 to move to the bottom, and then the nozzle 28 is controlled to align with the position of the feed trough 14, and the feed troughs 14 are cleaned one by one. The water pump 26 is started to draw the water in the water storage chamber 24 along the water pumping pipe 27 to the paper nozzle 28, and the water is sprayed through the nozzle 28 to flush the residual soil in the feed trough 14. The cover box 29 protects the outside of the feed trough 14 to prevent the water flow from hitting the feed trough 14 and splashing outward, causing mud to spread and pollute. By setting the feed trough 14 as a slope, the mud water after flushing can slide outward. The mud water sliding from the feed trough 14 flows along the slope of the guide block 30, falls on the filter plate 32, and then slides down along the slope of the filter plate 32. The mud water is filtered by the filter plate 32, and the filtered water passes through the filter plate 32 into the filter chamber 31, and enters the water storage chamber 24 for storage for reuse. The remaining mud remains on the filter plate 32, slides along the slope of the filter plate 32, and separates from the slide plate 6.

[0044] Specifically, the drying component includes a heating chamber 34, which is opened inside the skateboard 6 and located below the filter chamber 31. One side of the heating chamber 34 passes through the skateboard 6. The inner wall of the heating chamber 34 is provided with a heating wire 37. The bottom of the skateboard 6 is fixedly connected to an air pump 35, and the output end of the air pump 35 is fixedly connected to an exhaust pipe 36. One end of the exhaust pipe 36 extends to the interior of the heating chamber 34.

[0045] Through the above technical solution, after flushing the lowest feed trough 14, the slide 6 is controlled to move upward to clean several feed troughs 14 one by one. When the nozzle 28 cleans the upper feed trough 14, the heating chamber 34 is located at the feed trough 14 that has just been flushed below. The air pump 35 is started to draw the external air into the heating chamber 34 along the exhaust pipe 36. When the gas is discharged from the exhaust pipe 36, it passes through the heating wire 37 and enters the feed trough 14. The heating wire 37 is started to heat the gas entering the feed trough 14, thereby allowing the hot air to dry the flushed feed trough 14.

[0046] Specifically, two connecting pipes 38 are symmetrically fixedly connected to the outer wall of the slide 6, and a sleeve box 39 is fixedly connected between the two connecting pipes 38. The sleeve box 39 is located directly above the filter plate 32. A cavity 40 is opened inside the sleeve box 39. One end of the connecting pipe 38 extends to the inside of the cavity 40, and the other end of the connecting pipe 38 extends to the inside of the heating chamber 34. The outer wall of the sleeve box 39 is symmetrically fixedly connected to two air outlet pipes 41, and the air outlet pipes 41 are installed at an angle.

[0047] Through the above technical solution, as the gas in the heating chamber 34 flows into the heating chamber 34, the gas with a pressure greater than the saturation pressure is discharged outward along the connecting pipe 38. The gas discharged from the connecting pipe 38 enters the cavity 40 and is then discharged along the outlet pipe 41. By setting the outlet pipe 41 to an inclined state, the ejected gas is tilted and hits the inclined surface of the filter plate 32, which is convenient for blowing off the mud on the filter plate 32 and preventing the mud from staying on the filter plate 32 and causing blockage of the filter plate 32 and affecting filtration.

[0048] Specifically, the inner wall of the base 1 is equidistantly and slidingly connected with several second sliding shafts 43, the top of the second sliding shaft 43 is fixedly connected with a positioning block 42, the positioning block 42 is slidably connected to the base 1, the bottom of the second sliding shaft 43 is fixedly connected with a fixing ring 45, the top of the fixing ring 45 is fixedly connected with a scraper 46, the scraper 46 fits the outer wall of the drill rod 7 and the bottom is set as an annular inclined surface, the outer wall of the second sliding shaft 43 is sleeved with a second spring 44, the top of the second spring 44 is fixedly connected to the base 1, and the bottom of the second spring 44 is fixedly connected to the fixing ring 45; the top of the fixing ring 45 is fixedly connected with a U-shaped frame 47, the top of the inner wall of the U-shaped frame 47 is fixedly connected with a protrusion 48, the bottom of the protrusion 48 is set as a symmetrical inclined surface, the outer wall of the support frame 2 is fixedly connected with a second motor 49, the output end of the second motor 49 is fixedly connected with a cam 50, the cam 50 is set below the protrusion 48 and used in conjunction with the protrusion 48.

[0049] By the above technical solution, when the drill rod 7 is pulled out of the soil, the scraper 46 is attached to the outer wall of the drill rod 7 to scrape off the soil adhering to the drill rod 7, thereby preventing the soil adhering to the drill rod 7 from affecting the subsequent soil sampling. When the drill rod 7 moves to the top of the scraper 46, the scraped soil is likely to remain on the inclined surface at the bottom of the scraper 46. At this time, the second motor 49 is started to drive the cam 50 to rotate. When the raised end of the cam 50 rotates to the upper side, it presses against the inclined surface at the top of the protrusion 48. Under the push of the cam 50, the protrusion 48 moves upward, driving the U-shaped frame 47 to move upward, the fixing ring 45 to move upward, and the scraper 46 to move upward, pressing the second spring 44. When the raised end of the cam 50 rotates to a position disengaged from the protrusion 48, the squeezing of the cam 50 is lost. On the second spring 44, the scraper 46 moves downward and vibrates, thus reciprocating. As the second motor 49 is started, the scraper 46 is driven to continue to vibrate downward, thereby shaking off the adhering soil.

[0050] An operating method of a soil pollution prevention and treatment sampling auxiliary device is provided. The operating method is applicable to the above-mentioned soil pollution prevention and treatment sampling auxiliary device. The operating method steps are as follows:

[0051] S1: Start the first motor 3 to control the drill rod 7 to be inserted into the soil below, start the hydraulic cylinder 22 to control the slider 13 to move horizontally into the soil, and take soil samples;

[0052] S2: Start the electric telescopic rod 9 to control the card block 10 to move out of the card slot 11, start the first motor 3 to control the slide plate 6 to move up and down to adjust the position of the nozzle 28, and flush the soil remaining in the feed trough 14;

[0053] S3: Start the first motor 3 to control the slide plate 6 to move upward step by step, start the air pump 35 and the heating wire 37, and allow hot air to enter the feed trough 14 to dry the flushed feed trough 14.

[0054] When in use, the electric telescopic rod 9 is used to control the block 10 to move to the inside of the card slot 11, and the base 1 is moved to the top of the soil sampling. The first motor 3 is started to drive the screw rod 4 to rotate, so that the first connecting block 5 moves downward, and the slide plate 6 moves downward. The card slot 11 is limited by the block 10. When the slide plate 6 moves downward, it also drives the drill rod 7 to move downward, so that the drill rod 7 is inserted into the soil below. The hydraulic cylinder 22 is started to drive the lower pressure plate 23 to move downward, so that the slide rod 16 moves downward. When the slide rod 16 moves downward, it pushes several connecting shafts 17 to move downward and rotate. Under the push of several connecting shafts 17, several sliders 13 are extended outward and inserted into the soil horizontally, so that the soil enters the feed trough 14 for sampling. The slider 13 moves At the same time, the second connecting block 20 is driven to move, pressing the first spring 21. After the soil enters the feed chute 14 along the inclined surface on one side of the two stoppers 15, the hydraulic cylinder 22 controls the lower pressure plate 23 to move upward. Under the pull of the connecting shaft 17, the first spring 21 is cooperated to retract the slider 13 into the drill rod 7. Under the pull of the inclined surface on the other side of the two stoppers 15, the sampled soil is helped to break free from the ground, preventing the sampled soil from sliding out of the feed chute 14 due to the mutual adhesion between the soils. Subsequently, the first motor 3 controls the slide plate 6 to move upward, driving the drill rod 7 to move upward and out of the ground. By setting the feed chute 14 to an inclined surface, it is convenient to take out the sampled soil. When the drill rod 7 is pulled out of the soil, the scraper 46 fits the outer wall of the drill rod 7. The soil adhering to the drill rod 7 is scraped off to prevent the soil adhering to the drill rod 7 from affecting the subsequent soil sampling. When the drill rod 7 moves to the top of the scraper 46, the scraped soil is likely to remain on the inclined surface at the bottom of the scraper 46. At this time, the second motor 49 is started to drive the cam 50 to rotate. When the raised end of the cam 50 rotates to the upper side, it presses against the inclined surface at the top of the protrusion 48. Under the push of the cam 50, the protrusion 48 moves upward, driving the U-shaped frame 47 to move upward, causing the fixing ring 45 to move upward, driving the scraper 46 to move upward, and pressing the second spring 44. When the raised end of the cam 50 rotates to a position disengaged from the protrusion 48, the squeezing of the cam 50 is lost, and the second spring 44 causes the scraper 46 to move downward and vibrate, thus reciprocating. The motor 49 is started, driving the scraper 46 to vibrate downward continuously, so as to shake off the adhered soil, and water is filled into the water storage chamber 24 through the water inlet 25. After taking out the sampled soil, the block 10 is controlled to move out of the card slot 11 by the electric telescopic rod 9. When the block 10 is no longer limited, the slide 6 can slide freely on the drill rod 7. At this time, the first motor 3 is used to control the slide 6 to move to the bottom, and then the nozzle 28 is controlled to align with the position of the feed trough 14, and the feed troughs 14 are cleaned one by one. The water pump 26 is started, and the water in the water storage chamber 24 is sprayed along the water pumping pipe 27 to the paper pumping nozzle 28, and the residual soil in the feed trough 14 is washed. The outer side of the feed trough 14 is protected by the provided cover box 29.To prevent water flow from colliding with the feed trough 14 and splashing outward, causing mud to spread and pollute, the feed trough 14 is set to an inclined surface, so that the mud water after flushing can slide outward, and the mud water sliding from the feed trough 14 flows along the inclined surface of the guide block 30, falls on the filter plate 32, and then slides down along the inclined surface of the filter plate 32. The mud water is filtered by the filter plate 32, and the filtered water passes through the filter plate 32 into the filter chamber 31 and enters the water storage chamber 24 for storage and reuse. The remaining mud remains on the filter plate 32 and slides down along the inclined surface of the filter plate 32, separating from the slide plate 6. After flushing the lowest feed trough 14, the slide plate 6 is controlled to move upward to clean several feed troughs 14 one by one. When the nozzle 28 cleans the upper feed trough 14, the heating chamber 34 is at the bottom At the feed trough 14 that has just been flushed, the air pump 35 is started to draw the outside air into the heating chamber 34 along the air extraction pipe 36. When the air is discharged from the air extraction pipe 36, it passes through the heating wire 37 and enters the feed trough 14. The heating wire 37 is started to heat the air entering the feed trough 14, thereby allowing the hot air to dry the feed trough 14. As the air in the heating chamber 34 flows into the air, the air with a pressure greater than the saturation pressure is discharged outward along the connecting pipe 38. The air discharged from the connecting pipe 38 enters the cavity 40 and is then discharged along the air outlet pipe 41. By setting the air outlet pipe 41 to an inclined state, the ejected air is tilted and hits the inclined surface of the filter plate 32, which facilitates the blowing off of the mud on the filter plate 32 and prevents the mud from staying on the filter plate 32 and clogging the filter plate 32 and affecting the filtration.
