Description

Technical Field

[0001] This application relates to the field of soil pollutant exceedance detection technology, and in particular to a soil pollutant exceedance alarm device. Background Technology

[0002] Soil pollutants can be broadly classified into two categories: inorganic pollutants and organic pollutants. Inorganic pollutants mainly include acids, alkalis, heavy metals, salts, compounds containing radioactive elements such as cesium and strontium, and compounds containing arsenic, selenium, and fluorine. Organic pollutants mainly include organic pesticides, phenols, cyanides, petroleum, synthetic detergents, 3,4-benzo[a]pyrene, and harmful microorganisms from urban sewage, sludge, and manure. When the soil contains excessive amounts of harmful substances, exceeding its self-purification capacity, it causes changes in the soil's composition, structure, and function, inhibiting microbial activity and reaching a level that endangers human health—this is soil pollution.

[0003] A search revealed Chinese Patent Publication No. CN220399350U, which discloses a soil pollutant exceeding standard alarm device, relating to the field of soil pollutant detection technology. The device includes a detection box with a support assembly for swinging the box. The support assembly includes a base plate, a first support plate mounted on the base plate, and a second support plate mounted on the base plate. The detection box is rotatably connected to the detection box via a pin. This utility model has a reasonable design structure. It utilizes the detection assembly to detect the gas generated after heating, achieving the effect of analyzing and alarming pollutants in the soil sample. Furthermore, the support assembly swings the detection box, and under the action of the stirring assembly, the soil sample in the storage chamber is stirred and agitated, ensuring uniform heating and guaranteeing the accuracy of the soil sample detection results. The support assembly and inlet / outlet pipes complete the loading and unloading of soil, effectively reducing soil residue in the storage chamber after unloading and preventing residual soil from affecting the accuracy of subsequent test results.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following defects in this patent:

[0005] The patent requires soil sampling first, followed by stirring and heating of the soil before testing, which slows down the testing process and prevents simultaneous detection of pollutants in multiple soil layers.

[0006] Therefore, in response to the above problems, the applicant provides a soil pollutant exceeding the standard alarm device. Utility Model Content

[0007] In order to solve the problems mentioned in the background art, this application provides a soil pollutant exceeding the standard alarm device.

[0009] A soil pollutant exceeding the standard alarm device includes three positioning rings. Each positioning ring is equipped with a layered detection mechanism, which includes a surface sensor, a middle layer sensor, a deep layer sensor, and a wiring conduit. The surface sensor, the middle layer sensor, and the deep layer sensor are respectively installed on the three positioning rings in sequence. A wiring conduit is fixedly connected to one side of each of the surface sensor, the middle layer sensor, and the deep layer sensor, and an electric wire is installed in the wiring conduit.

The top end of the top connecting cylinder is fixedly connected to the top surface of the top connecting cylinder.

[0013] Optionally, each of the three connecting cylinders has an annular hole at its bottom, and each of the three annular holes is connected to a connecting plate groove. The connecting plate groove passes through the connecting cylinder, and the three protective covers are located in the three annular holes respectively. The connecting plate is located in the connecting plate groove, and the top of the connecting plate is a "C" shaped handle.

[0014] Optionally, positioning rings are bolted to the bottom surfaces of all three connecting cylinders. The surface sensor, middle sensor, and deep sensor are all connected to the connecting plate via wires.

[0021] 1. This utility model inserts surface, middle and deep sensors into the soil at different depths, thereby enabling targeted detection of pollutants in each soil layer at once, thus increasing the comprehensiveness of the detection.

[0022] 2. This utility model uses a ground-contacting base ring and a sliding column that are vertically upward to allow the pressure plate to slide up and down in the sliding column, thereby driving the soil inserter to be vertically inserted into the soil. This avoids the soil inserter being tilted when inserted into the soil, which would cause errors in the insertion depth and thus errors in the detection.

[0023] 3. In this utility model, when the soil inserter is inserted into the soil, the protective cover blocks the hollow area between two adjacent connecting cylinders, thereby preventing sand and sharp objects from piercing and damaging the surface sensor, middle sensor and deep sensor, thus effectively protecting the surface sensor, middle sensor and deep sensor.

[0030] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0031] This application discloses a soil pollutant exceeding the standard alarm device.

[0032] like Figure 1-5 As shown, a soil pollutant exceeding the standard alarm device includes three positioning rings 2. Each positioning ring 2 is equipped with a layered detection mechanism, which includes a surface sensor 3, a middle layer sensor 4, a deep layer sensor 5, and a wiring conduit 6. The surface sensor 3, the middle layer sensor 4, and the deep layer sensor 5 are installed sequentially on the three positioning rings 2. The wiring conduit 6 is fixedly connected to one side of each of the surface sensor 3, the middle layer sensor 4, and the deep layer sensor 5. An electric wire 60 is installed in the wiring conduit 6.

[0033] The soil inserter 1 is equipped with a shielding and lifting mechanism, which includes a connecting plate 7 and a protective cover 8. Three protective covers 8 are fixedly connected to the connecting plate 7.

[0034] The soil inserter 1 is equipped with a vertical pressing mechanism, which includes a ground contact base ring 16, a sliding column 17 and a pressure plate 18. Multiple sliding columns 17 are fixedly connected in a ring array on the top surface of the ground contact base ring 16, and the multiple sliding columns 17 are slidably connected to the pressure plate 18.

[0035] Please see Figures 1 to 4The soil inserter 1 comprises a connecting cylinder 100, an annular hole 101, a connector 102, a connecting plate groove 103, a connecting cylinder top 104, and a cone 105. There are three connecting cylinders 100 in total. The connector 102 is fixedly connected between two adjacent connecting cylinders 100. The connector 102 is fixedly connected between the bottom connecting cylinder 100 and the cone 105. The top surface of the top connecting cylinder 100 is fixedly connected to the connecting cylinder top 104. The connector 102 is made of stainless steel to ensure stable connection performance. The height of the top connecting cylinder 100 is more than twice the height of the middle connecting cylinder 100 and the bottom connecting cylinder 100.

[0036] Please see Figures 1 to 4 Each of the three connecting cylinders 100 has an annular hole 101 at its bottom, and all three annular holes 101 are connected to the connecting plate groove 103. The connecting plate groove 103 passes through the connecting cylinder 100. The three protective covers 8 are located in the three annular holes 101 respectively. The connecting plate 7 is located in the connecting plate groove 103. The top of the connecting plate 7 is a "C" shaped handle 70. The depth and curvature of the annular hole 101 are adapted to the depth and curvature of the protective cover 8. The annular hole 101 limits the position of the protective cover 8 to prevent it from rotating.

[0037] Please see Figure 2 Positioning rings 2 are bolted to the bottom of each of the three connecting cylinders 100. The surface sensor 3, the middle sensor 4, and the deep sensor 5 are all connected to the connecting plate 7 via wires 60. The connecting plate 7 is fixedly installed to the outer circumference of the top connecting cylinder 100. The installed cable conduit 6 effectively protects the wires 60 from soil accumulation.

[0038] Please see Figure 3 and Figure 4 A fixed bracket 11 is fixedly connected to the outer circumference of the top connecting cylinder 100. A nut 12 is threadedly connected to the fixed bracket 11. A sleeve 120 is rotatably connected to the end of the nut 12. A clamping plate 13 is fixedly connected to the sleeve 120. The clamping plate 13 is engaged in the "C"-shaped handle 70. The connecting plate 7 is raised by the "C"-shaped handle 70 to prevent the connecting plate 7 from falling. The operator rotates the nut 12 in the threaded hole of the fixed bracket 11 while balancing the clamping plate 13 with one hand. As the nut 12 rotates and pushes forward, the clamping plate 13 is engaged in the "C"-shaped handle 70. The "C"-shaped handle 70 is then restricted, thus preventing the connecting plate 7 from falling.

[0039] Please see Figure 3A magnet 14 is embedded in the bottom of the "C"-shaped handle 70, and an iron block 15 is embedded in the top connecting cylinder 100. The magnet 14 is magnetically connected to the iron block 15. The top of the top connecting cylinder 100 and the bottom of the "C"-shaped handle 70 are both provided with slots for embedding the magnet 14 and the iron block 15, respectively. When the connecting plate 7 moves down and the protective cover 8 covers the hollow between two adjacent connecting cylinders 100, the connection relationship between the magnet 14 and the iron block 15 ensures the stability of the connecting plate 7 and the protective cover 8 in a static state, that is, it prevents them from moving up and down.

[0040] Please see Figure 1 The top of the connecting cylinder 104 is fixedly connected to a pressure plate 18. The pressure plate 18 is arranged in a ring array with multiple vertical sliding grooves. The sliding grooves are used to limit the vertical sliding of the pressure plate 18 in the sliding groove column 17.

[0041] Please see Figure 5 The top of multiple sliding columns 17 is fixedly connected to a top ring 170, the outer circumference of the pressure plate 18 is symmetrically fixedly connected to a pressure handle 180, and the top of the ground contact base ring 16 is fixedly connected to multiple support columns 160 in a ring array.

[0042] Please see Figure 5 A data display screen 9 is fixedly connected to the outer circumference of the top connecting cylinder 100. An alarm 10 is installed on the top of the data display screen 9. Both the data display screen 9 and the alarm 10 are electrically connected to a power supply module 61.

[0043] The implementation principle of the soil pollutant exceeding the standard alarm device in this application embodiment is as follows:

[0044] The two operators first lift the pressure handle 180, which drives the pressure plate 18 to slide upward in the slide column 17. The pressure plate 18 drives the soil inserter 1 to lift upward, and at this time the ground contact base ring 16 is placed on the soil.

[0045] Two operators press the handle 180, which drives the pressure plate 18 to slide downward in the chute column 17. The cone 105 that first contacts the soil penetrates into the soil. The bottom connecting cylinder 100, the middle connecting cylinder 100, and the top connecting cylinder 100 are inserted into the soil in sequence. When the bottom surface of the pressure plate 18 contacts the top surface of the support column 160, the vertical insertion is completed. At this time, the surface sensor 3 on the top connecting cylinder 100 is about 20cm deep in the soil. The surface sensor 3 is used to detect heavy metals such as lead and cadmium on the soil surface. The middle sensor 4 is about 40cm deep in the soil and is used to detect organic pollutants such as petroleum hydrocarbons and pesticides in the soil. The deep sensor 5 is about 60cm deep in the soil and is used to detect deep pollutants such as mine seepage. The surface sensor 3, the middle sensor 4, and the deep sensor 5 transmit the detected vertically to the data display screen 9 through the processor. At the same time, when the displayed value exceeds the preset value, the CPU will control the alarm 10 to sound an alarm.

[0046] When the soil inserter 1 is about to be inserted into the soil, the "C"-shaped handle 70 and the top surface of the top connecting cylinder 100 are in a magnetic adsorption state. At the same time, the protective cover 8 covers the hollow parts of the two adjacent connecting cylinders 100. After the soil inserter 1 is inserted into the soil, the operator lifts the "C"-shaped handle 70 upward to move the connecting plate 7 and the protective cover 8 upward. At this time, the hollow parts between the two connecting cylinders 100 allow the soil or groundwater to come into contact with the surface of the surface sensor 3, the middle sensor 4 and the deep sensor 5, thus facilitating the operator's detection.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
