Description

Technical Field

[0001] The present invention relates to the technical field of soil monitoring, and in particular to a monitoring device and a monitoring method for monitoring the penetration and volatilization of soil pollutants. Background Art

[0002] At present, when it is necessary to monitor various minerals, organic matter and pollutants in the soil, most of them use soil samplers to sample the target area, and then analyze the sampled soil through a soil analyzer to measure the content of various minerals, organic matter and pollutants in the soil. This method monitors the process of soil contact with the outside world for too long, resulting in changes in the penetration and volatilization of some components in the soil as the external environment changes.

[0003] In the existing technology, soil sampling is easily affected by the external environment, causing the various components of the soil to change, reducing the actual content of each component, and it is difficult to achieve equal sampling in the process of collecting soil, and the weight of the equally sampled soil cannot be adjusted, and comparative experiments cannot be performed, resulting in multiple samplings that waste time. In addition, there are certain requirements for the depth of the soil during the sampling process, and the ground often has slopes or uneven areas, which makes the sampled soil depth and the actual depth have a certain error, and it is impossible to obtain the monitoring data actually needed.

[0004] In view of the above problems, the present invention provides a monitoring device and a monitoring method for monitoring the penetration and volatilization of soil pollutants. Summary of the invention

[0005] The object of the present invention is to provide a monitoring device and a monitoring method for monitoring the penetration and volatilization of soil pollutants. The movable plate is moved by pushing a hand push rod to drive the roller to roll and move to the ground to be detected. One of the sleeve rings is slid to make the limit frame break away from the restriction of the gravity ball. At this time, if the ground is uneven, the movable plate will tilt, so that the slider slides in the inner cavity of the first slide groove, which indicates that the ground is uneven. The position of the threaded rod on the movable plate is changed by rotating the hand push rod, and the contact between the roller and the ground becomes the contact between the convex ball and the ground, so that the movable plate remains horizontal. At this time, one of the sleeve rings is slid again to observe whether the gravity ball moves once to judge whether the movable plate is horizontal, thereby ensuring that the drill bit always drills vertically into the ground, so that the sampling soil depth is consistent with the actual sampling depth. The first gear is driven to rotate by the operation of the first motor, and the rotation of the first gear drives the second gear to rotate, and the rotation of the second gear drives the sleeve rod to rotate, and the rotation of the sleeve rod drives the second turntable to rotate, and the rotation of the second turntable drives the first turntable to rotate.

At this time, the second turntable 943 moves with the up and down movement of the control ring 946, that is, the socket position of the sleeve 944 and the collecting tube 942 changes, so that the capacity between the collecting tube 942 and the sleeve 944 changes, so that the amount of soil sampled each time can be controlled, thereby controlling the amount of sampled soil, which is convenient for control experiments.

[0046] In summary: by pushing the hand push rod 3 to drive the roller 2 to roll, the movable plate 1 is moved to the ground to be detected, and one of the rings 58 is slid to make the limit frame 510 break away from the restriction of the gravity ball 57. At this time, if the ground is uneven, the movable plate 1 will tilt, so that the slider 56 slides in the inner cavity of the first slide groove 55, which means that the ground is uneven. By rotating the hand push rod 42, the position of the threaded rod 41 on the movable plate 1 is changed, and the contact between the roller 2 and the ground becomes the contact between the convex ball 45 and the ground, so that the movable plate 1 remains horizontal. At this time, one of the rings 58 is slid again to observe whether the gravity ball 57 moves once to judge whether the movable plate 1 is horizontal, thereby ensuring The drill bit 93 always drills vertically toward the ground, and can monitor whether the equipment is inserted vertically through the horizontal detection component 5. The correction component 4 ensures that the equipment is inserted vertically into the ground, so that the sampled soil depth is the same as the actual depth, making the monitoring data more accurate. The first motor 953 drives the first gear 952 to rotate, the rotation of the first gear 952 drives the second gear 954 to rotate, the rotation of the second gear 954 drives the sleeve rod 955 to rotate, the rotation of the sleeve rod 955 drives the second turntable 943 to rotate, the rotation of the second turntable 943 drives the first turntable 941 to rotate, and the first gear 952 is half smooth, so the first turntable 941 presents periodic rotation, Each time the rotation is half a circle, it is ensured that the soil taken out by the sampling tube 91 falls between the collecting tube 942 and the sleeve 944 in the hopper 98. When the bottom end of the bottom cover 945 contacts the inclined surface of the control ring 946, the bottom cover 945 is opened, and the soil falls into the protrusion 963 for centralized collection. The belt 964 is driven to rotate by the operation of the third motor 966, and the rotation of the belt 964 drives the collecting plate 961 to rotate. The collection plate 961 drives the collecting box 962 to rotate, so that the collecting box 962 collects the soil. The first limiting rod 76 is rotated to make the first limiting rod 76 and the block 77 fall off and engage. At this time, the collected soil is centrally processed to avoid long-term exposure. In order to affect the volatilization of each component outside and ensure the accuracy of the data, the rotation of the fourth motor 971 drives the third gear 972 to rotate, and the rotation of the third gear 972 drives the rack 973 to move up and down. At this time, the rack 973 drives the adjusting frame 974 to move up and down, and the movement of the adjusting frame 974 drives the control ring 946 to move up and down. At this time, the second turntable 943 moves with the up and down movement of the control ring 946, that is, the socket position of the sleeve 944 and the collecting tube 942 changes, so that the capacity between the collecting tube 942 and the sleeve 944 changes, so that the amount of soil sampled each time can be controlled, which is convenient for comparative experiments, avoids the need for multiple sampling, and saves time.
