Abstract
Description
Technical Field
[0001] The present invention relates to the field of soil detection, and particularly to a soil detection device and method. Background Art
[0002] With the vigorous development of industrialization, harmful substances such as sewage are directly placed outside without treatment, resulting in soil pollution and a decrease in the organic content in the soil. To accurately evaluate the degree of soil pollution and formulate remediation, it is necessary to detect the soil at the polluted site, and then select a treatment method according to the content of harmful substances in the soil. Soil environmental monitoring refers to determining the environmental quality (or pollution degree) and its change trend through the measurement of representative values of factors affecting soil environmental quality. Generally, the so-called soil monitoring refers to soil environmental monitoring, which generally includes technical contents such as site layout and sampling, sample preparation, analysis methods, result representation, data statistics, and quality evaluation.
[0003] Currently, in the study of deep soil pollution, the drilling method is usually used to obtain a complete soil column, and the occurrence states of pollutants at different depths are detected after stratification cutting. To prevent the loss of target substances due to water evaporation, microbial activities, or changes in redox potential during sample exposure, it is necessary to quickly fix the segmented soil sections with a curing agent. For example, in the detection of volatile organic compounds, curing helps to maintain the original concentration of the sample and avoid volatilization loss; in the study of pollutant migration mechanisms, by maintaining the soil moisture gradient through curing, isotope tracer data can be accurately obtained to calculate the diffusion coefficient. In addition, layered detection can also reveal the vertical differentiation laws of heavy metals, pesticide residues, and nutrients in the profile, providing a key basis for pollution source tracing.
[0004] Existing technologies mostly rely on transferring the segmented samples to the laboratory for curing operations, but there are significant technical defects in the interval from soil column cutting to curing completion: the cut soil is exposed to the air, resulting in water evaporation and organic matter volatilization; at the same time, it is difficult for manual spraying to cover the deep cutting surface, and the permeability difference is significant; the step-by-step operations of segmentation and curing are time-consuming, and the single processing time is too long, which not only reduces the analysis accuracy but may also mislead the design of the remediation plan.
[0005] Therefore, a technical solution to solve the above problems is needed. Summary of the Invention

[0027] Refer to Figure 1 As shown, it is a schematic structural diagram of a soil detection device of the present invention.
[0028] Refer to Figures 1 to 3 , a soil detection device, including a detection box 100, a cutting and curing structure 200, and a supporting structure 300. The cutting and curing structure 200 and the supporting structure 300 are both arranged in the detection box 100. The supporting structure 300 is used to support the soil to be detected, and the cutting and curing structure 200 is used to cut the soil supported on the supporting structure 300 and cure it. When cutting the soil column, the curing of the cutting surface is completed synchronously to avoid sample exposure and improve the detection accuracy.
[0029] Refer to Figure 1 , Figure 2 , the detection box 100 is a box-type structure, with a sealed inner cavity 110 formed inside. The inner cavity 110 is used to install the supporting structure 300 and the cutting and curing structure 200, and is used to accommodate the soil and perform cutting and curing on the soil. Generally, the detection box 100 is a substantially cuboid-shaped structure, which is hollow inside. A box cover structure 120 for opening it can be provided on one side or the top of it. The box cover structure 120 can be opened to put the soil to be detected on the supporting structure 300 inside for operations such as detection, cutting, and fixing.
[0030] The cutting and curing structure 200 and the supporting structure 300 are relatively arranged in the detection box 100 and can be driven to approach or move away from each other, so that the cutting and curing structure 200 can perform cutting and curing operations on the soil on the supporting structure 300.
[0031] Preferably, when the cutting and curing structure 200 is installed in the detection box 100, a part of the cutting and curing structure 200 can be driven to move inside the detection box 100, approaching or moving away from the supporting structure 300, for operations such as switching and curing the soil on the supporting structure 300, which is convenient to use.
[0032] Further, within the detection box 100, the supporting structure 300 is installed at the bottom inside the box, and the cutting and fixing structure is arranged at the top of the detection box 100. The cutting and curing structure 200 can be driven to move within the detection box 100, approaching or moving away from the supporting structure 300, for operations such as cutting and curing the soil on the supporting structure 300.
[0033] Specifically, in this embodiment, the cutting and curing structure 200 includes a bracket 210 fixed to the top of the detection box 100, a U-shaped support frame 220 movably installed on the bracket 210, and a driving device 230 for driving the support frame 220 to move up and down on the bracket 210. A plurality of segmentation and curing groups are evenly spaced along the axis of the support frame 220. Each segmentation and curing group includes a cutting knife 224 and a plurality of liquid spraying heads 225. When driven by the air cylinder, the support frame 220 can move up and down, enabling the liquid spraying heads 225 and the cutting knife 224 thereon to approach or move away from the soil on the supporting structure 300, for cutting the soil and spraying the curing liquid.
[0034] Preferably, the driving device 230 is an air cylinder, which is installed on the bracket 210 and is connected to the support frame 220. By driving the air cylinder, the support frame 220 can be driven to move relative to the bracket 210, enabling the cutting knife 224 and the liquid spraying heads 225 to approach or move away from the soil on the supporting structure 300.
[0035] The support frame 220 includes a connecting column 221 connected to the bracket 210 and a support plate 222 connected to the connecting column 221. The connecting column 221 is movably installed on the bracket 210. The support plate 222 can move relative to the bracket 210 through the connecting column 221. The support plate 222 is also connected to the driving end of the air cylinder and can move relative to the bracket 210 through the driving of the air cylinder, and move within the detection box 100. The cutting knife 224 and the liquid spraying heads 225 are both arranged on the support plate 222, and they are both arranged on the downward-facing side of the support plate 222, and can face downward the supporting structure 300 at the bottom of the detection box 100, facilitating the cutting and curing of the soil on the supporting structure 300.
[0036] Preferably, the cutting knife 224 is a cutting knife 224 with a generally conical cross-section, with its bottom being a tip, and the diameter gradually increasing at one end connected to the support frame 220. Two inclined surfaces 2241 are formed on both sides of the cutting knife 224, enabling the cutting knife 224 to more conveniently cut the soil, and the gradually increasing diameter of the cutting knife 224 also facilitates sufficient separation of the cut soil.
[0037] Further, in order to cure the side surface of the cut soil, the side surface of the cutting knife 224 can also output the fixing liquid.
[0038] Specifically, refer to Figure 3, in this embodiment, an internal liquid adding cavity 2242 is provided in the cutting knife 224. The liquid adding cavity 2242 is filled with a solidifying liquid. A plurality of liquid leakage ports 2243 communicating with the liquid adding cavity 2242 are provided on the cutting surface of the cutting knife 224. The plurality of liquid leakage ports 2243 are respectively arranged on the inclined surfaces 2241 on both sides of the cutting knife 224; a pressure valve 2244 is provided at each liquid leakage port 2243, and the liquid output from the liquid leakage port 2243 can be controlled through the pressure valve 2244 for solidification treatment. Moreover, an extended liquid adding pipe (not shown) and a pressurizing air pump (not shown) communicating into the liquid adding cavity 2242 are provided in the liquid adding cavity 2242. The liquid adding pipe can be externally connected to the solidifying liquid, and the pressurizing air pump pressurizes the liquid adding cavity 2242 to make the solidifying liquid flow out from the pressure valve 2244.
[0039] Preferably, two liquid adding cavities 2242 are provided in each cutting knife 224. The two liquid adding cavities 2242 are symmetrically arranged left and right in the cutting knife 224. The two liquid adding cavities 2242 are respectively used to communicate with the liquid leakage ports 2243 on both sides of the cutting knife 224. By providing two liquid adding cavities 2242 in the cutting knife 224, different solidifying liquids can be output on both sides of the cutting knife 224. Moreover, the cutting knife 224 is installed on the support frame 220 and can be driven to rotate, or the cutting knife can be driven to alternately use different solidifying liquids, so that when the cutting knife 224 is used, different solidifying liquids can be used for solidification according to the different soil requirements on both sides of the cutting, or different solidifying liquids can be used in the same soil, making it more convenient to use.
[0040] Specifically, in this embodiment, each cutting knife 224 has two groups of liquid adding pipes, and electromagnetic valves are respectively provided on the liquid adding pipes, namely A valve 2245 and B valve 2246. Two independent liquid adding cavities 2242 are respectively filled with liquid A and liquid B, and the liquid adding cavity 2242 is a conical surface with a circumferential angle of 180°. The cutting knife 224 is rotatably installed on the support frame 220 through a servo motor 2247. The cutting knife 224 is driven to rotate by the servo motor 2247, so that different solidifying liquids can be output on different sides. When in use, the A valve 2245 is opened, liquid A is filled into the liquid adding cavity 2242 and pressurized. Liquid A flows out through the pressure valve 2244 to control the liquid leakage port 2243. The cutting knife 224 descends and inserts into the soil, and the soil is solidified by liquid A; after several minutes, the A valve is closed, the cutting knife 224 rises, the servo motor 2247 drives the cutting knife 224 to reverse 180 degrees, the B valve is opened, liquid B is filled into the liquid adding cavity 2242 and pressurized, and liquid B flows out from the other side of the cutting knife 224 through the pressure valve 2244 to control the liquid leakage port 2243. The cutting knife 224 descends and inserts into the soil, and the soil is solidified by liquid B. It can be understood that the liquid adding pipe is a flexible pipe with a sufficient length reserved to cooperate with the 180-degree rotation of the cutting knife 224.
[0041] It can be understood that the length of the cutting knife 224 is less than the distance between the cutting knives 224, so that the cutting knife 224 can be driven to rotate in the detection box 100.
[0042] When the supporting structure 300 is installed in the detection box 100, it has a plane 311 facing upward for placing soil, and this plane 311 extends to the inner side wall of the detection box 100 inside the detection box 100. An accommodating cavity for accommodating soil is formed between the plane 311 and the inner side wall of the detection box 100, so that the soil can be stably placed on the supporting structure 300.
[0043] Specifically, in this embodiment, the supporting structure 300 includes a supporting plate 310 installed in the detection box 100. The supporting plate 310 can be installed in the detection box 100 through the connecting column 221. Its top surface is a flat supporting plane 311. The soil can be placed on the supporting plane 311 for support, and the supporting plane 311 faces the cutting and curing structure 200 inside the detection box 100. When the cutting and curing structure 200 is driven, it can approach or move away from the soil on the supporting surface.
[0044] It can be understood that in some other embodiments, the cutting and curing structure 200 can also be fixedly installed in the detection box 100, while the supporting structure 300 is arranged in the detection box 100 to be lifted and lowered for approaching or moving away from the cutting and curing structure 200, so as to realize that the cutting and curing structure 200 can perform cutting and curing operations on the soil on the supporting structure 300.
[0045] A method for soil detection, using the above-mentioned soil detection equipment, includes the following steps: Soil positioning: Place the soil to be measured on the supporting plate 310 of the supporting structure 300, and adjust the number and position of the cutting knives 224 to align with the preset cutting positions.
[0046] Cutting and curing: The air cylinder drives the support frame 220 to descend, the cutting knives 224 cut into the soil, and at the same time, multiple liquid spraying heads 225 spray the curing liquid towards the soil column to cure the soil.
[0047] Among them, during cutting and curing, by using the fact that the cutting knives 224 can rotate, during the cutting process of the cutting knives 224, the first layer of curing liquid (liquid A) and the second layer of curing liquid (liquid B) are respectively injected into the soil through rotation, and there is an interval of a period of time between the two, such as 1 - 3 minutes. Liquid A is selected as a fast-reacting curing agent (such as a heavy metal chelating agent), and liquid B is selected as a film-forming curing agent (such as an organic stabilizer). Its purpose is to quickly fill the micropores on the surface / cutting surface of the soil after the reaction of liquid A to form a physical barrier layer to prevent the secondary migration of pollutants. At the same time, when cutting the soil, using the newly exposed highly active sites on the cutting surface to quickly fix the target pollutants; secondly, liquid A provides chemical anchor points for liquid B, and liquid B provides physical protection for liquid A, and the combination of the two makes the curing efficiency higher.
[0048] Reset and sampling: After cutting is completed, the support frame 220 rises, and the segmented soil is automatically separated, that is, the segmentation and solidification of the soil column are completed, and the soil directly enters the detection link.
[0049] Before the cutting and solidification steps, the following steps can also be set: Pressurized liquid injection: During use, the solidifying liquid is filled into the liquid adding cavity 2242, the pressurizing air pump is started, and pressurization is carried out on the liquid adding cavity 2242. When the pressure inside the liquid adding cavity 2242 exceeds the conduction pressure of the pressure valve 2244, the solidifying liquid flows out through a plurality of liquid leakage ports 2243 respectively, and the solidifying liquid wets the cutting surface of the cutter 224. During the cutting process of the cutter 224, the solidifying liquid on the cutting surface of the cutter 224 adheres to the cutting surface of the soil column for solidification. During the cutting process of the pressurizing air pump, continuous pressurization is carried out to ensure that the solidifying liquid penetrates deep into the soil cutting surface.
[0050] In the soil detection device of the present invention, the cutter 224 of the cutting and solidifying structure 200 has the function of applying the solidifying liquid. Cooperating with the liquid spraying head 225, immediate solidification can be achieved after segmentation. Especially since the cutting surface is cut from the outside to the inside, physical changes (such as water evaporation, organic matter volatilization, soil shrinkage, crack generation, etc.) are very likely to occur at this cutting surface. By solidifying the cutting surface of the soil column during the cutting process of the cutting knife, the accuracy of the later soil detection results can be guaranteed.
[0051] The above are only some embodiments of the present invention. For those of ordinary skill in the art, without departing from the inventive concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
