Description

A rapid sampling device for detecting heavy metal pollution in soil Technical Field

[0001] This utility model relates to the field of soil testing technology, specifically a rapid sampling device for detecting heavy metal pollution in soil. Background Technology

[0002] Heavy metal pollution in soil refers to an environmental problem caused by human activities or natural processes, in which the concentration of specific metal elements such as lead, cadmium, mercury, and arsenic in the soil exceeds normal background levels or national and local safety standards. These heavy metals can enter the soil through various pathways, such as industrial emissions, mining, fertilizer and pesticide use, vehicle exhaust emissions, and improperly disposed solid waste.

[0003] The existing patent announcement number CN209400258U discloses an integrated device for rapid detection and sampling of heavy metals in soil, relating to the technical field of soil heavy metal detection equipment. This integrated device includes a heavy metal detection unit, a telescopic mechanism, and a drill bit. One end of the telescopic mechanism is connected to the heavy metal detection unit, and the other end is detachably connected to the drill bit. The heavy metal detection unit has a cavity that can accommodate the telescopic mechanism. The drill bit is used to sample the soil. This integrated device for rapid detection and sampling of heavy metals in soil can both initially determine whether there is heavy metal pollution in the soil and directly sample based on the determination and identification, avoiding the need for blindly collecting large amounts of soil samples in the field, thus reducing workload and saving costs.

[0004] Using the above-mentioned technical solution, after soil sampling, the soil tends to adhere to the inner wall of the sampling tube, making cleaning inconvenient and hindering subsequent soil sampling and combined testing, potentially leading to soil contamination. Therefore, we provide a rapid sampling device for detecting heavy metal pollution in soil. Summary of the Invention

[0005] The purpose of this invention is to provide a rapid sampling device for detecting heavy metal pollution in soil, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rapid sampling device for detecting heavy metal pollution in soil, comprising a base, a support on one side of the top of the base, two telescopic cylinders on the top of the support, a connecting plate at the bottom of each of the two telescopic cylinders, a sampling tube between the two connecting plates, a sampling port on one side of the top of the sampling tube, a motor on the top of the sampling tube, a transmission paddle inside the sampling tube, a water tank on the top of the base away from the support, a water pump on the top of the water tank, a water delivery hose on one side of the water pump, and a moving mechanism at each of the four corners of the bottom of the base.

[0007] As a further preferred embodiment of this technical solution, the moving mechanism includes a caster wheel mounting bracket, with a pulley rotatably mounted on the bottom of the caster wheel mounting bracket, and a handrail fixedly connected to the top of the base on the side away from the support.

[0013] This utility model provides a rapid sampling device for detecting heavy metal pollution in soil, which has the following features:

[0014] Beneficial effects:

[0015] (1) This utility model controls the forward rotation of the transmission paddle by a motor. When the sampling tube descends, the bottom of the sampling tube can be drilled into the soil in conjunction with the rotating transmission paddle. At this time, the motor is started to control the transmission paddle to reverse, so that the soil can be transported upward. The soil sample is taken out from the sampling tube through the sampling port. The water pump is started to draw the cleaning water pre-stored in the water tank into the water delivery hose. The water is then transported to the sampling tube through the water delivery hose to wash the soil remaining on the inner wall of the sampling tube and the transmission paddle. As a result, the soil is mixed, ensuring the accuracy of soil heavy metal detection.

[0016] (2) The present invention can facilitate the movement of the device through the provided moving mechanism, which significantly improves the efficiency and flexibility of operation; at the same time, the moving mechanism can reduce the intensity of manual labor and realize an efficient, safe and standardized sampling process.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: As shown in Figures 1-4, in this embodiment, a rapid sampling device for detecting heavy metal pollution in soil includes a base 11. A support 12 is provided on one side of the top of the base 11. Two telescopic cylinders 13 are provided on the top of the support 12. The bottom of the support 12 is fixedly connected to the top of the base 11. Two slots on the top of the support 12 are fixedly installed with telescopic cylinders 13. A connecting plate 15 is provided at the bottom of each of the two telescopic cylinders 13. The bottom of the telescopic cylinder 13 is fixedly connected to the top of the connecting plate 15. One side of the connecting plate 15 is fixedly connected to the outside of a sampling cylinder 14. A sampling cylinder 14 is provided between the two connecting plates 15. A sampling port 16 is provided on the top of one side of the sampling cylinder 14. A motor 17 is provided on the top of the sampling cylinder 14. The sampling cylinder 14 is equipped with a transfer paddle 18. A motor 17 is fixedly installed on the top of the sampling cylinder 14. The output end of the bottom of the motor 17 is fixedly connected to the top of the transfer paddle 18. A water tank 19 is provided on the top of the base 11 away from the bracket 12. A water pump 110 is provided on the top of the water tank 19. The bottom of the water tank 19 is fixedly connected to the top of the base 11. The bottom of the water pump 110 is fixedly installed on the top of the water tank 19. The input end of the bottom of the water pump 110 extends into the water tank 19. A water delivery hose 111 is provided on one side of the water pump 110. The output end of the water pump 110 is fixedly connected to one end of the water delivery hose 111. The other end of the water delivery hose 111 is fixedly connected to the inner wall of the slot opened on the side of the sampling cylinder 14 away from the sampling port 16. A moving mechanism 2 is provided at each of the four corners of the bottom of the base 11.

[0025] In this embodiment, when it is necessary to use this device to sample heavy metals in the soil, the device can be moved to the soil area where sampling is required. By simultaneously activating two telescopic cylinders 13, the sampling cylinder 14 between the two connecting plates 15 and the motor 17 can be raised and lowered. By activating the motor 17, the transmission paddle 18 is controlled to rotate forward. When the sampling cylinder 14 descends, the rotating transmission paddle 18 allows the bottom of the sampling cylinder 14 to penetrate into the soil. At this time, activating the motor 17 controls the transmission paddle 18 to rotate in reverse, which can transport the soil upward. When the soil sample is transferred to the top of the sampling tube 14, it can be taken out from the sampling tube 14 through the sampling port 16. In order to avoid the soil remaining in the sampling tube 14 from mixing with the soil sampled later, the water pump 110 can be started to draw the cleaning water pre-stored in the water tank 19 into the water delivery hose 111. The water is then transferred to the sampling tube 14 through the water delivery hose 111 to wash the soil remaining on the inner wall of the sampling tube 14 and the transfer paddle 18, thereby preventing the soil from becoming mixed and ensuring the accuracy of soil heavy metal detection.

[0026] As shown in Figures 1-4, the moving mechanism 2 includes a caster wheel mounting bracket 21, with a pulley 22 rotatably mounted on the bottom of the caster wheel mounting bracket 21, and a handrail 23 fixedly connected to the top of the base 11 on the side away from the bracket 12.

[0027] In this embodiment, the provided moving mechanism 2 facilitates the movement of the equipment, significantly improving work efficiency and flexibility; at the same time, the moving mechanism 2 can reduce the intensity of manual labor and realize an efficient, safe and standardized sampling process.

[0028] This invention provides a rapid sampling device for detecting heavy metal pollution in soil, the specific working principle of which is as follows:

[0029] When this device is needed to sample heavy metals in the soil, it is first moved to the target sampling area. By simultaneously activating two telescopic cylinders 13, the sampling cylinder 14 and motor 17 between the connecting plates 15 are driven to rise and fall as a whole. The motor 17 is activated to control the transmission paddle 18 to rotate forward. As the sampling cylinder 14 descends, the rotating transmission paddle 18 can cut the bottom of the sampling cylinder 14 into the soil. Then, the motor 17 is switched to reverse, and the transmission paddle 18 lifts the soil sample to the top of the sampling cylinder 14 and removes it through the sampling port 16. To prevent residual soil from affecting subsequent sampling, the water pump 110 can be activated to draw cleaning water from the water tank 19 and inject it into the sampling cylinder 14 through the water delivery hose 111 to rinse the inner wall and transmission paddle 18, avoiding cross-contamination of samples and ensuring the accuracy of heavy metal detection. In addition, this design reduces manual intervention through automated operation and improves sampling efficiency. At the same time, the built-in cleaning system effectively avoids the deviation of detection results caused by soil residue. It is especially suitable for heavy metal pollution monitoring scenarios with multiple samples and high precision requirements.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
