Technical Field
[0001] This utility model relates to the field of vehicle-mounted nuclear-contaminated soil screening, and more specifically, to a vehicle-mounted nuclear-contaminated soil screening device. Background Technology
[0002] Nuclear-contaminated soil refers to a special type of contaminated soil where radioactive materials have entered the soil environment due to human nuclear activities (such as nuclear accidents, nuclear tests, and leaks from nuclear facilities), resulting in radioactivity levels significantly higher than the natural background value, posing a potential threat to the ecosystem and human health. Nuclear-contaminated soil screening devices are technical equipment used to rapidly and accurately detect the activity of radionuclides (such as cesium-137, strontium-90, and plutonium-239) in the soil and to locate contaminated areas. Its core functions include sampling, detection, data processing, and analysis.
[0003] Existing nuclear-contaminated soil screening devices typically use portable screening devices to screen and test soil. These devices are characterized by single-person operation and portability. However, when using portable screening devices to screen nuclear-contaminated soil, only one soil sample can be taken from the same area for screening at a time. Multiple soil samples cannot be screened and tested simultaneously, resulting in inaccurate screening results. Furthermore, portable screening devices are less efficient than vehicle-mounted nuclear-contaminated soil screening devices. Utility Model Content
[0004] One objective of this invention is to provide a new technical solution for a vehicle-mounted nuclear contaminated soil screening device.
[0005] According to a first aspect of the present invention, a vehicle-mounted nuclear contaminated soil screening device is provided, comprising: a vehicle-mounted plate and a through groove, wherein the through groove is provided inside the vehicle-mounted plate, and a screening and detection mechanism and a stabilizing mechanism are provided on the vehicle-mounted plate, wherein the screening and detection mechanism includes a rotating column, the rotating column is rotatably mounted on the vehicle-mounted plate, a top plate is fixedly connected to the upper end of the rotating column, a connecting seat is connected to the bottom end of the top plate through a driving component, a soil sampling component is fixedly connected to the side wall of the connecting seat, and a screening component is provided on the vehicle-mounted plate;
[0006] The drive assembly includes an electric cylinder, which is fixedly connected to the bottom end of the top plate, and the bottom output end of the electric cylinder is fixedly connected to the connecting seat;
[0007] The soil sampling assembly includes a soil sampler, which is fixedly connected to the side wall of the connecting seat. A sampling tube is fixedly installed at the bottom of the soil sampler, and the bottom of the sampling tube is pointed. The screening assembly includes a screening disc, which is fixedly connected to the upper end of the vehicle plate by a fixing column. A through hole is opened inside the screening disc, and a test tube is threadedly installed at the bottom of the through hole.
[0008] Preferably, a servo motor is mounted on the upper end of the vehicle board, and a rotating rod is fixedly connected to the output end of the servo motor via a coupling. A drive gear is fixedly connected to the bottom end of the rotating rod, and a driven gear is connected to the surface of the drive gear via tooth meshing. A connecting column is fixedly connected to the upper end of the driven gear via a connecting rod. The connecting column can rotate inside the vehicle board, and the connecting column is fixedly connected to the rotating column.
[0009] Preferably, a limiting ring is fixedly connected to the side wall of the connecting column, and the limiting ring is rotatably disposed in a circular groove opened inside the vehicle plate.
[0010] Preferably, the bottom ends of the driving gear and the driven gear are fixedly connected to a support column, and the support column is rotatably connected to the inside of the vehicle plate through a bearing seat.
[0011] Preferably, the stabilizing mechanism includes a connecting rod, which is fixedly connected to the outer wall of the connecting seat. The end of the connecting rod away from the connecting seat is fixedly connected to the outer wall of the soil sampler. Two sets of connecting seats are provided, and the two sets of connecting seats are fixedly connected by a support rod.
[0012] Preferably, a telescopic support rod is fixedly connected to the upper end of the connecting seat, and the upper end of the telescopic support rod is fixedly connected to the bottom end of the top plate.
[0013] 1. This utility model utilizes the cooperation of a rotating column, top plate, connecting seat, soil sampler, sampling tube, screening disc, through hole, test tube, electric cylinder, servo motor, rotating rod, driving gear, driven gear, and connecting column to move the vehicle to the soil to be tested. The electric cylinder is activated, causing the bottom connecting seat to rise and fall, which in turn moves the soil sampler assembly downwards, allowing it to enter the nuclear-contaminated soil through the through-slot for soil sampling. After sampling, the electric cylinder moves the soil sampler assembly upwards, positioning it parallel to the upper surface of the screening disc. The rotating unit then drives the rotating column to adjust... The device rotates 180 degrees to align the sampling tube with the through-holes inside the screening disc. Then, the electric cylinder moves the sampling tube downwards again, immersing the soil in the fluorescent agent inside the test tube. Combined with an external spectrometer, this allows for convenient screening of nuclear-contaminated soil. This vehicle-mounted nuclear-contaminated soil screening device can simultaneously screen multiple groups of nuclear-contaminated soil using the vehicle-mounted soil sampling component, drive, and rotation components. Multiple samples can be taken from the same location for simultaneous screening and testing, resulting in higher detection effectiveness and efficiency, and improving the practicality and efficiency of the device.
[0014] 2. This utility model, through the cooperation of telescopic support rods, connecting rods, and support rods, utilizes two sets of connecting seats to jointly support the soil sampler in its soil sampling assembly. The two sets of connecting seats are symmetrically arranged along the central axis of the soil sampler, making it more stable when supporting the soil sampler's lifting and lowering movements. This avoids the problem of imbalance caused by the soil sampling assembly becoming heavier after soil removal. As a result, this vehicle-mounted nuclear contaminated soil screening device can maintain stability during the soil sampling process of nuclear contaminated soil, avoiding imbalance and deviation that would affect the soil sampling effect, and improving the practicality and stability of the device.

[0026] like Figure 1-4 As shown, one embodiment of this utility model is provided:
[0027] A vehicle-mounted nuclear contaminated soil screening device. The vehicle-mounted plate 111, through groove 112, electric cylinder 219 and servo motor 220 used in this application are products that can be directly purchased on the market. Their principles and connection methods are existing technologies well known to those skilled in the art.
[0028] Includes: vehicle-mounted plate 111 and through groove 112. Through groove 112 is opened inside the vehicle-mounted plate 111. Screening and detection mechanism 2 and stabilizing mechanism 3 are provided on the vehicle-mounted plate 111. Screening and detection mechanism 2 includes rotating column 211. Rotating column 211 is rotatably mounted on vehicle-mounted plate 111. Top plate 212 is fixedly connected to the upper end of rotating column 211. Connecting seat 213 is connected to the bottom end of top plate 212 through driving component. Soil sampling component is fixedly connected to the side wall of connecting seat 213. Screening component is provided on vehicle-mounted plate 111.
[0029] The drive assembly includes an electric cylinder 219, which is fixedly connected to the bottom of the top plate 212, and the bottom output end of the electric cylinder 219 is fixedly connected to the connecting seat 213.
[0030] The soil sampling assembly includes a soil sampler 214, which is fixedly connected to the side wall of the connecting seat 213. A sampling tube 215 is fixedly installed at the bottom of the soil sampler 214, and the bottom of the sampling tube 215 is sharp. The screening assembly includes a screening disc 216, which is fixedly connected to the upper end of the vehicle plate 111 by a fixing post. A through hole 217 is opened inside the screening disc 216, and a test tube 218 is threadedly fitted at the bottom of the through hole 217.
[0031] When using this vehicle-mounted nuclear-contaminated soil screening device, the vehicle is moved to the location of the nuclear-contaminated soil to be tested. The electric cylinder 219 is activated, causing it to lift and lower the bottom connecting seat 213, which in turn moves the soil sampling component downwards simultaneously. This component enters the nuclear-contaminated soil through the through-slot 112 to collect soil samples. After soil collection, the electric cylinder 219 moves the soil sampling component upwards, positioning it parallel to the upper surface of the screening disc 216. The rotating unit then rotates the rotating column 211 180 degrees, aligning the sampling tube 215 with the through-holes 217 inside the screening disc 216. Subsequently, the electric cylinder 219 moves the sampling tube 215 downwards again, placing the soil in the fluorescent agent inside the test tube 218 for detection with an external spectrometer. This allows for convenient and accurate multi-group screening of nuclear-contaminated soil, improving the screening effect and efficiency.
[0032] A servo motor 220 is mounted on the upper end of the vehicle board 111. The output end of the servo motor 220 is fixedly connected to a rotating rod 221 via a coupling. A drive gear 222 is fixedly connected to the bottom end of the rotating rod 221. A driven gear 223 is connected to the surface of the drive gear 222 via tooth meshing. A connecting column 224 is fixedly connected to the upper end of the driven gear 223 via a rotating rod. The connecting column 224 can rotate inside the vehicle board 111. The connecting column 224 is fixedly connected to the rotating column 211.
[0033] When the rotating component is running, the servo motor 220 drives the rotating rod 221 to rotate, which in turn drives the driving gear 222 to rotate synchronously. Under the meshing action of the teeth, the driven gear 223 is driven to rotate synchronously. With the cooperation of the connecting column 224, the rotating column 211 can be easily driven to rotate.
[0034] A limiting ring 225 is fixedly connected to the side wall of the connecting column 224, and the limiting ring 225 is rotatably set in a circular groove opened inside the vehicle plate 111;
[0035] When the connecting post 224 rotates, the limiting ring 225 rotates synchronously in the circular groove opened inside the vehicle plate 111, thereby limiting the connecting post 224 and making its rotation more stable.
[0036] A support column 226 is fixedly connected to the bottom end of the driving gear 222 and the driven gear 223. The support column 226 is rotatably connected to the inside of the vehicle plate 111 through a bearing seat.
[0037] When the driving gear 222 and the driven gear 223 rotate, their bottom ends are supported by the support column 226 and the bearing seat, making the rotation more stable.
[0038] The stabilizing mechanism 3 includes a connecting rod 312, which is fixedly connected to the outer wall of the connecting seat 213. One end of the connecting rod 312 away from the connecting seat 213 is fixedly connected to the outer wall of the soil sampler 214. The connecting seat 213 is provided with two sets, and the two sets of the connecting seat 213 are fixedly connected by the support rod 313.
[0039] When using this vehicle-mounted nuclear contaminated soil screening device, the soil sampler 214 in its soil sampling assembly is supported by two sets of connecting seats 213. The two sets of connecting seats 213 are symmetrically arranged along the central axis of the soil sampler 214, which makes it more stable when supporting the soil sampler 214 for lifting and lowering, and avoids the problem of imbalance caused by the soil sampling assembly becoming heavier after the soil is removed.
[0040] A telescopic support rod 311 is fixedly connected to the upper end of the connecting seat 213, and the upper end of the telescopic support rod 311 is fixedly connected to the bottom end of the top plate 212;
[0041] When the electric cylinder 219 drives the bottom connecting seat 213 to move up and down, the telescopic support rod 311 moves up and down synchronously to provide stable support force, making the moving motion of the connecting seat 213 more stable.
[0042] Working principle:
[0043] When using this vehicle-mounted nuclear-contaminated soil screening device, move the vehicle to the soil to be tested, start the electric cylinder 219 to drive the bottom connecting seat 213 to rise and fall, and then drive the soil sampling component to move downwards synchronously, so that it enters the nuclear-contaminated soil through the through groove 112 to collect soil. After the soil is collected, use the electric cylinder 219 to drive the soil sampling component to move upwards, so that it is positioned parallel to the upper surface of the screening disc 216. Use the rotating unit to drive the rotating column 211 to rotate 180 degrees, so that the sampling tube 215 corresponds one-to-one with the through hole 217 opened inside the screening disc 216. Then, the electric cylinder 219 moves the sampling tube 215 downwards again, so that the soil is in the fluorescent agent inside the test tube 218. With the help of an external spectrometer, the nuclear-contaminated soil can be conveniently screened.
[0044] When using this vehicle-mounted nuclear contaminated soil screening device, the soil sampler 214 in its soil sampling assembly is supported by two sets of connecting seats 213. The two sets of connecting seats 213 are symmetrically arranged along the central axis of the soil sampler 214, which makes it more stable when supporting the soil sampler 214 for lifting and lowering, and avoids the problem of imbalance caused by the soil sampling assembly becoming heavy after the soil is removed. The operation is then completed.
