DETAILED DESCRIPTION

[0027] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and corresponding drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] The following describes in detail the technical solutions of a soil detection device for soil heavy metal remediation provided by various embodiments of the present invention in conjunction with the accompanying drawings.

[0029] Reference Figures 1 to 3 As shown, an embodiment of the present invention provides a soil detection device for soil heavy metal remediation, including a detection frame 1, a detection movable part 2 is provided in the detection frame 1, and the detection movable part 2 is slidably matched with the detection frame 1, and a detection instrument 3 and a detection displacement part 4 are provided in the detection movable part 2, and the detection instrument 3 is located on the detection displacement part 4, and the detection displacement part 4 can drive the position of the detection instrument 3 to move in the detection movable part 2; a detection cleaning structure 5 is provided on the detection frame 1, and the detection cleaning structure 5 is slidably matched with the detection frame 1, and the detection cleaning structure 5 is located below the detection instrument 3.

[0030] In this embodiment, the detection moving part 2 includes a horizontal moving cylinder 21, a vertical moving cylinder 22 and a horizontal moving block 23. A slide groove 11 is provided at the top position of the detection frame 1. The horizontal moving block 23 is located in the slide groove 11 and the horizontal moving block 23 slides with the slide groove 11. The horizontal moving cylinder 21 is horizontally connected in the slide groove 11 and the telescopic end of the horizontal moving cylinder 21 is connected to the horizontal moving block 23. The vertical moving cylinder 22 is located at the top position of the horizontal moving block 23.

[0031] When testing the soil, the vertical moving cylinder 22 works to drive the position of the detection instrument 3 to move downward, and the position of the detection instrument 3 is moved into the soil to be tested. The heavy metals in the soil are detected by the detection instrument 3. After the detection is completed, when the detection instrument 3 is cleaned and cleaned, the horizontal moving cylinder 21 works to drive the horizontal moving block 23 to move horizontally in the slide 11, and the position of the detection instrument 3 is moved to the upper position of the water collection cover 54. Thereafter, the vertical moving cylinder 22 works to drive the position of the detection instrument 3 to move downward, so that the cleaning of the detection instrument 3 can be realized.

[0032] In this embodiment, the detection displacement member 4 includes a mounting box 41, a displacement motor 42, a displacement gear 43, a fixed collar 44 and two sliders 45. The mounting box 41 is connected to the telescopic end of the vertical moving cylinder 22. Two support frames 46 are provided in the mounting box 41. The two sliders 45 are symmetrically arranged in the fixed collar 44. The fixed collar 44 slides on the two support frames 46 through the two sliders 45. The displacement motor 42 is located on the side wall of one of the support frames 46. The displacement gear 43 is located on the main shaft of the displacement motor 42. A vertically arranged displacement tooth plate 47 is provided on one of the sliders 45. The displacement tooth plate 47 is engaged with the displacement gear 43. The detection instrument 3 is vertically connected in the fixed collar 44. The bottom of the mounting box 41 is provided with a through hole for the movement of the detection instrument 3.

[0033] When detecting heavy metals at different depths in the soil or protecting the detection instrument 3, the displacement motor 42 drives the displacement gear 43 to rotate on the displacement tooth plate 47, which drives the displacement tooth plate 47 to move up and down on the support frame 46, so that the fixed ring 44 moves downward on the two support frames 46 through the two sliders 45. Because the distribution of heavy metals at different depths in the soil is also different, some heavy metals may have a low content in the surface soil due to rain leaching and other effects, and accumulate in deeper soil layers; on the contrary, other heavy metals may be mainly concentrated in the surface soil, so it is necessary to move the position of the detection instrument 3 downward when detecting heavy metals in the soil, so that detection of different depths of the soil can be achieved when detecting heavy metals in the soil;

[0034] After the detection instrument 3 completes the detection and cleaning of the soil, it is necessary to move the detection instrument 3 into the installation box 41 to protect the detection end of the detection instrument 3 to prevent dust or external impact on the detection end, which may cause damage to the detection instrument 3.

[0035] In this embodiment, the detection and cleaning structure 5 includes a sliding base 51, a cleaning swing assembly 52 and a multi-directional cleaning assembly 53. The sliding base 51 is slidably connected to the detection frame 1, the cleaning swing assembly 52 is connected to the sliding base 51, and a water collecting cover 54 is provided on the cleaning swing assembly 52. ​​The multi-directional cleaning assembly 53 is distributed on the water collecting cover 54 in a circular shape at equal intervals.

[0036] In this embodiment, the sliding base 51 has two slide rails 511 at the bottom, and the detection frame 1 is provided with a slideway for the two slide rails 511 to slide. Two locking screws 512 are provided on both sides of the side wall of the detection frame 1, and the locking screws 512 are in conflict with the sliding base 51.

[0037] When cleaning the bottom of the detection instrument 3, the two slide rails 511 on the sliding base 51 will be pushed to move horizontally in the two slides respectively, and the detection and cleaning structure 5 will be moved to the lower position of the detection instrument 3. By rotating the two locking screws 512, the position of the sliding base 51 can be fixed on the detection frame 1. After completing one cleaning, loosen the two locking screws 512 and move the position of the sliding base 51 away from the bottom of the detection instrument 3. Then, the sewage after cleaning in the water collection cover 54 can be discharged to the outside, and the discharge method can be extracted by a water pump.

[0038] In this embodiment, the cleaning swing assembly 52 includes a swing motor 521, a swing plate 522, a swing rod 523, a swing frame 524 and a swing top plate 525. The swing motor 521 is located on the sliding base 51, and the swing plate 522 is connected to the main shaft of the swing motor 521. The sliding base 51 is provided with two symmetrically arranged support plates 526. The swing frame 524 is rotatably connected to the two support plates 526. The swing frame 524 is provided with a rotatably connected swing shaft 527, and the swing shaft 527 is provided with a support column 528. The swing top plate 525 is horizontally connected to the support column 528, and the two ends of the swing rod 523 are connected to the swing plate 522 and the support column 528.

[0039] When cleaning, the swing motor 521 drives the swing plate 522 to rotate, thereby rotating the swing rod 523. The swing of the swing rod 523 drives the support column 528 to swing, thereby swinging on the two support plates 526 through the swing frame 524, thereby driving the position of the swing top plate 525 to swing in multiple directions. When cleaning the bottom of the detection instrument 3,

[0040] It can fully cover different areas of the bottom. The shape and structure of the bottom of the measuring instrument may be complex, with various depressions, protrusions or corners. By swinging the top plate 525 to drive the side cleaning brush discs 532 and the center cleaning brush disc to swing in multiple directions, the cleaning brush discs can reach every corner of the bottom.

[0041] Adapt to bottoms of different shapes and sizes: The shapes and sizes of the bottoms of different testing instruments vary greatly. The swinging cleaning method can better adapt to this diversity. For bottoms with larger areas, swinging can make the brush plate move in a larger range, increasing the cleaning area; for bottoms with irregular shapes, such as oval or beveled bottoms, swinging can allow the brush plate to clean along the contour of the bottom, fit the shape of the bottom, and avoid blind spots in cleaning.

[0042] Increased scrubbing frequency and angle variation: During the oscillation process, the scrubbing angle and frequency of the side cleaning brush discs 532 and the center cleaning brush disc continuously change. This dynamic cleaning method removes dirt faster than fixed-angle cleaning. For example, when the brush discs oscillate at a certain amplitude and frequency, the bristles interact with the bottom stain in a more diverse manner, not just with simple one-way friction but also with multi-angle scraping and agitation. This is very effective for removing stubborn stains such as dried samples and sticky chemical residues, and can clean the bottom in a shorter time.

[0043] Utilizing the centrifugal force generated by the swinging to assist in cleaning: The movement of the swinging top plate 525 causes the cleaning brush disc to generate centrifugal force, which can throw the cleaning liquid and dirt outward to prevent the dirt from being deposited again in the cleaned area. At the same time, the centrifugal force also helps the cleaning liquid to better penetrate into the gap between the dirt and the bottom of the instrument, thereby enhancing the cleaning effect. For example, when cleaning the bottom of an instrument with sticky dirt, the centrifugal force can help the cleaning liquid separate the dirt from the bottom surface, making the dirt easier to be removed by the brush disc.

[0044] In this embodiment, an annular tube 55 is provided in the water collecting cover 54, and a plurality of water spray heads 56 are provided on the annular tube 55, and the plurality of water spray heads 56 are arranged toward the center position; the multi-directional cleaning component 53 includes a plurality of cleaning parts, each of the cleaning parts includes a side cleaning motor 531 and a side cleaning brush plate 532, the side cleaning motor 531 is located on the water collecting cover 54, and the side cleaning brush plate 532 is connected to the main shaft of the side cleaning motor 531; the multi-directional cleaning component 53 also includes a central cleaning motor 533 and a central cleaning brush plate 534, the central cleaning motor 533 is located at the center of the water collecting cover 54, and the central cleaning brush plate 534 is connected to the main shaft of the central cleaning motor 533.

[0045] After completing a test, when cleaning the bottom of the detection instrument 3, the ring tube 55 sprays deionized water or distilled water to the detection end at the bottom of the detection instrument 3 through multiple water spray heads 56. Deionized water or distilled water does not contain impurities and will not leave mineral residues after rinsing. For some special detection heads, it may be necessary to select a suitable organic solvent, such as ethanol, acetone, etc., for rinsing according to its material and the substance being detected. For example, after detecting some organic pollutants, rinsing with acetone can effectively remove the organic matter remaining on the surface of the detection head; then the side cleaning motor 531 works to drive the side cleaning brush plate 532 to work and clean the side of the detection end, and the center cleaning motor 533 works to drive the center cleaning brush plate 534 to rotate and clean the bottom of the detection end;

[0046] The detection end of the detection instrument 3 is usually complex in shape, with different surfaces such as sides and bottoms. By having the side cleaning motor 531 drive the side cleaning brush 532 to clean the sides, and the center cleaning motor 533 drive the center cleaning brush 534 to clean the bottom, it is possible to ensure that all parts of the detection end are effectively cleaned. This comprehensive cleaning method can reach these different locations, avoiding the situation where only one surface is cleaned while other parts are missed, just like wiping a complex-shaped artwork from all angles, leaving no corner untouched. When testing different samples, if the detection end is not cleaned thoroughly, the residue from the previous sample may contaminate the next sample, thereby affecting the accuracy of the test results. Comprehensive cleaning can effectively remove residual substances from the previous test at the detection end, avoiding cross-contamination.

[0047] The foregoing is merely an embodiment of the present invention and is not intended to limit the present invention. It will be apparent to those skilled in the art that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are intended to be included within the scope of the claims of the present invention.
