Description

Technical Field

[0001] The invention belongs to the technical field of soil and water conservation assessment, and in particular is an intelligent assessment device for collecting polluted soil and water. Background Art

[0002] With the rapid development of industrialization and urbanization, environmental pollution problems are becoming increasingly serious. Among them, water and soil pollution has become a global environmental challenge. Water and soil pollution not only affects the balance and stability of the ecosystem, but also poses a potential threat to human health. Accurately and efficiently collecting and evaluating the status of polluted water and soil is of great significance for formulating effective pollution control strategies, protecting the environment and safeguarding human health.

[0003] A Chinese patent with publication number CN110672363A discloses a multi-point intelligent collection and detection device for contaminated soil, which mainly includes a detection box, a soil collection element, an intelligent detection element, and a power supply. The soil collection element includes a collection installation drawer, a telescopic sleeve, and a collection head. The lower end of the outer wall of the collection head is sleeved with an annular bracket, and the bottom end of the annular bracket is evenly provided with multiple loosening gear rods along the circumferential direction; through the setting of the loosening gear rods, the soil in the collection and detection area can be loosened to avoid the soil being too hard, thereby damaging the drill bit or shortening the service life of the drill bit; through the setting of the collection head, the spiral collection piece can be prevented from being exposed all the time and easily bent, affecting the soil collection effect and thus reducing the detection efficiency; at the same time, multi-point collection of soil at different depths can be performed; it has the advantages of convenient collection, accurate detection, and intelligent integration, and is suitable for large-scale promotion.

[0004] In the current existing technology, a spiral collection port and a spiral collection piece are used to collect soil from multiple sites. However, the deep soil contains not only soil but also water, so the soil is very sticky. If it is discharged directly from the discharge port, some soil in the collection piece may be difficult to discharge. This soil is mixed with the soil collected next time, which will lead to inaccurate detection of ion content results, and thus the collection piece cannot work continuously at the same location.

DETAILED DESCRIPTION

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0037] like Figures 1 to 7As shown, an intelligent assessment device for collecting contaminated water and soil according to an embodiment of the present invention includes: a second detection box 1; a first telescopic cylinder 31, installed inside the detection box 1; a second telescopic cylinder 32, slidably connected to the inside of the first telescopic cylinder 31; a fixed cylinder 34, fixed to the bottom of the second telescopic cylinder 32, and provided with a third motor 38 inside; a sampling cylinder 35, fixed to the bottom of the fixed cylinder 34; six sampling spoons 4 are provided, and two of the sampling spoons 4 are symmetrically arranged on both sides of the sampling cylinder 35; an auxiliary mechanism is provided inside the sampling cylinder 35; the auxiliary mechanism includes a second reciprocating screw rod 41 rotatably connected to the inside of the sampling cylinder 35, and the top of the second reciprocating screw rod 41 is fixed to the output shaft of the third motor 38; three moving blocks 42 are threadedly connected to the reciprocating screw rod, and two sides of the moving block 42 are rotatably connected to each other by a pin shaft. Connecting rod 43, three fixed plates 44 are fixed on the inner wall of the sampling tube 35, and two sliders 45 are slidably connected to the fixed plates 44, and the tops of the sliders 45 are rotatably connected to the bottom of the connecting rod 43 through pins; the sampling spoons 4 are respectively fixed to the bottoms of the sliders 45; the sampling spoons 4 are respectively slidably connected to the sampling tube 35; the auxiliary mechanism also includes a push plate 46 slidably connected to the inner wall of each sampling spoon 4; an electric push rod 461 is fixed to the inner wall of the sampling spoon 4, and the output end of the electric push rod 461 is fixed to the push plate 46; a heater 462 is fixed on the side wall of the push plate 46 close to the electric push rod 461; an ion detector 463 is fixed on the other side wall of the push plate 46; both ends of the fixed plate 44 are fixed with a sealing plate 47, and the sealing plate 47 cooperates with the sampling spoon 4 respectively.

[0038] In the prior art, when collecting soil, since deep soil contains not only soil but also water, the soil is very sticky, and some soil in the collection piece may be difficult to discharge. These soils are mixed with the soil collected next time, which will lead to inaccurate detection of ion content results, thereby causing the collection piece to be unable to work continuously at the same location; when the auxiliary mechanism provided by the present invention is in use, when sampling, by turning on the third motor 38, the output shaft of the third motor 38 drives the second reciprocating screw 41 to rotate, and the second reciprocating screw 41 drives the moving block 42 to move downward, and the moving block 42 drives one end of the connecting rod 43 to move downward through the pin shaft, and the other end of the connecting rod 43 drives the slider 45 to slide on the fixed plate 44 through the pin shaft, thereby driving the sampling spoon 4 to extend out of the sampling tube 35 through the slider 45. The sampling tube 35 is then driven to rotate for sampling. During testing, the heater 462 is turned on to heat the sample in the sampling spoon 4 to allow the polluted gas in the soil to escape. The ion detector 463 is turned on to detect the outflowing polluted gas, thereby indirectly detecting the heavy metals and organic matter in the pollutants in the polluted soil. The test results are then sent to the test box 1. Finally, the test results are displayed on the display screen 13, and the system analyzes the composition of the polluted water and soil, assesses the pollution status, and facilitates the staff to quickly take protective measures. During discharging, the electric push rod 461 is turned on, and the push plate 46 is driven to move by the output end of the electric push rod 461. The sample in the sampling spoon 4 is pushed out of the sampling spoon 4 by the push plate 46, thereby cleaning the inside of the sampling spoon 4.

[0039] During the test, the electric push rod 461 can be turned on, and the output end of the electric push rod 461 drives the push plate 46 to reciprocate several times, so that the sample shakes in the sampling spoon 4, accelerates the heating of the sample, and improves the test efficiency.

[0040] like Figure 3 and Figure 4 As shown, two first reciprocating screws 21 are rotatably connected to the inner wall of the detection box 1 through bearings; the top ends of the first reciprocating screws 21 are fixedly connected to a rotating wheel 24, and a belt 25 is sleeved between the two rotating wheels 24; the two first reciprocating screws 21 are threadedly connected to a lifting plate 23; two guide rods 22 are fixedly connected to the inner wall of the detection box 1; one end of the lifting plate 23 is slidably connected to the two guide rods 22; the top of the detection box 1 is fixedly connected to a first motor 2, and the output shaft of the first motor 2 is fixedly connected to the top of one of the first reciprocating screws 21.

[0041] The rotating wheel 24, belt 25 and first reciprocating screw 21 provided by the present invention are used to extend the sampling tube 35 out of the bottom of the detection box 1 when in use. By turning on the first motor 2, the output shaft of the first motor 2 drives the connected first reciprocating screw 21 to rotate, and the first reciprocating screw 21 drives the connected rotating wheel 24 to rotate, and the rotating wheel 24 drives another rotating wheel 24 to rotate through the belt 25, and the other rotating wheel 24 drives the connected first reciprocating screw 21 to rotate. The synchronous rotation of the two first reciprocating screws 21 drives the lifting plate 23 to move. When the lifting plate 23 moves, the lifting plate 23 slides on the guide rod 22, and the guide rod 22 limits the lifting plate 23 to move in the vertical direction; the lifting plate 23 drives the first telescopic cylinder 31, the second telescopic cylinder 32 and the sampling tube 35 to move, so that the sampling tube 35 can extend out of the outside of the sampling tube 35.

[0042] like Figure 3 As shown, the top of the lifting plate 23 is fixedly connected to the second motor 3, the output shaft of the second motor 3 is rotatably connected to the lifting plate 23 through a bearing, and the output shaft of the second motor 3 is fixedly connected to the top of the first telescopic cylinder 31; the bottom of the sampling cylinder 35 is fixedly connected to a rotating rod 36, and a drill bit 37 is provided on the outside of the rotating rod 36.

[0043] The drill bit 37 provided by the present invention is used to loosen contaminated soil and water when in use. By turning on the second motor 3, the output shaft of the second motor 3 drives the first telescopic cylinder 31, the second telescopic cylinder 32, the fixed cylinder 34 and the sampling cylinder 35 to rotate, and the sampling cylinder 35 drives the rotating rod 36 to rotate, and the rotating rod 36 drives the drill bit 37 to rotate, and the soil is loosened by the drill bit 37, which facilitates sampling by the sampling cylinder 35 and the sampling spoon 4.

[0044] like Figure 3 As shown, a cylinder is fixedly connected to the top inner wall of the first telescopic cylinder 31, and the output end of the cylinder is fixedly connected to the bottom inner wall of the second telescopic cylinder 32; two limit rods 33 are symmetrically fixed to the outer wall of the second telescopic cylinder 32, and the limit rods 33 are both slidably connected to the inside of the first telescopic cylinder 31.

[0045] When the limiting rod 33 provided by the present invention is in use, the second telescopic cylinder 32 is restricted from moving in the vertical direction by the limiting rod 33 during its up and down movement, and the second telescopic cylinder 32 is restricted from rotating along with the rotation of the first telescopic cylinder 31 by the limiting rod 33 during its rotation.

[0046] like Figure 5 As shown, the fixing plate 44 has two sliding openings symmetrically formed thereon, and the sliders 45 are slidably connected in the sliding openings respectively.

[0047] The sliding opening provided by the present invention is used to limit the sliding direction of the slider 45 when in use. When the moving block 42 moves, the moving block 42 drives one end of the connecting rod 43 to move through the pin shaft, and the other end of the connecting rod 43 drives the slider 45 to slide in the sliding opening through the pin shaft, and the sliding opening is used to keep the slider 45 always sliding on the fixed plate 44.

[0048] like Figure 7 As shown, a fixing seat 51 is fixed to the bottom of the detection box 1 , a protective cover 5 is slidably connected to the bottom end of the fixing seat 51 , and a plurality of springs 52 are fixed between the protective cover 5 and the fixing seat 51 .

[0049] The protective cover 5 provided by the present invention is used to prevent the splashing of broken soil when in use. By setting the spring 52, the protective cover 5 is suitable for protecting the ground with different slopes. By setting the protective cover 5 to prevent the splashing of broken soil, it can prevent the broken soil from splashing on the workers, which poses certain safety hazards.

[0050] Figure 2 As shown, moving wheels 11 are respectively installed at the four corners of the bottom of the detection box 1; a telescopic pull rod 12 is provided on the rear side wall of the detection box 1; and a display screen 13 and multiple control buttons 14 are provided on the front side wall of the detection box 1.

[0051] The movable wheels 11 provided by the present invention facilitate moving the evaluation device to a specified position; the telescopic pull rod 12 facilitates pushing and pulling by workers of different heights; the display screen 13 is used to display monitoring results and evaluation results; and the control button 14 is used to control the working status of each motor.

[0052] like Figure 6 As shown, two slide grooves 464 are provided on the inner wall of the sampling spoon 4 , and both ends of the push plate 46 are slidably connected in the slide grooves 464 .

[0053] The present invention provides a sliding groove 464. When the push plate 46 moves, the push plate 46 slides in the sliding groove 464. The sliding groove 464 limits the push plate 46 from moving in the horizontal direction.

[0054] Working principle: When sampling, by turning on the third motor 38, the output shaft of the third motor 38 drives the second reciprocating screw 41 to rotate, and the second reciprocating screw 41 drives the moving block 42 to move downward, and the moving block 42 drives one end of the connecting rod 43 to move downward through the pin shaft, and the other end of the connecting rod 43 drives the slider 45 to slide on the fixed plate 44 through the pin shaft, so that the sampling spoon 4 is driven to extend into the sampling tube 35 through the slider 45, and then the sampling tube 35 is driven to rotate for sampling; when detecting, the heater 462 is turned on to heat the sample in the sampling spoon 4 to make the polluted gas in the soil escape, and the ion detector 463 is turned on to detect the outflowing polluted gas, thereby indirectly detecting the polluted gas. The heavy metals and organic matter in the pollutants in the contaminated soil are detected, and then the test results are sent to the detection box 1. Finally, the test results are displayed on the display screen 13, and the system analyzes the composition of the contaminated water and soil, evaluates the pollution status, and facilitates the staff to quickly take protective measures; when discharging, by turning on the electric push rod 461, the output end of the electric push rod 461 drives the push plate 46 to move, and the push plate 46 pushes the sample in the sampling spoon 4 out of the sampling spoon 4, thereby cleaning the inside of the sampling spoon 4; during the detection, the electric push rod 461 can be turned on, and the output end of the electric push rod 461 drives the push plate 46 to reciprocate several times, so that the sample shakes in the sampling spoon 4, accelerates the heating of the sample, and improves the detection efficiency;

[0055] By turning on the first motor 2, the output shaft of the first motor 2 drives the connected first reciprocating screw 21 to rotate, and the first reciprocating screw 21 drives the connected runner 24 to rotate, and the runner 24 drives another runner 24 to rotate through the belt 25, and the other runner 24 drives the connected first reciprocating screw 21 to rotate. The synchronous rotation of the two first reciprocating screws 21 drives the lifting plate 23 to move. When the lifting plate 23 moves, the lifting plate 23 slides on the guide rod 22, and the guide rod 22 limits the lifting plate 23 to move in the vertical direction; the lifting plate 23 drives the first telescopic cylinder 31, the second telescopic cylinder 32 and the sampling cylinder 35 to move, so that the sampling cylinder 35 can extend out of the outside of the sampling cylinder 35;

[0056] By turning on the second motor 3, the output shaft of the second motor 3 drives the first telescopic cylinder 31, the second telescopic cylinder 32, the fixed cylinder 34 and the sampling cylinder 35 to rotate, and the sampling cylinder 35 drives the rotating rod 36 to rotate, and the rotating rod 36 drives the drill bit 37 to rotate, and the drill bit 37 is used to loosen the soil, which facilitates sampling by the sampling cylinder 35 and the sampling spoon 4.
