Sampling and detecting integrated device for soil environment detection

Abstract

The invention discloses a sampling and detecting integrated device for soil environment detection, and mainly relates to the field of sampling and detection devices. The sampling and detecting integrated device comprises a periphery casing, a liquid collection bottle, a detection device assembly and a control alarm device, wherein a spiral conical head is arranged at the bottom of the periphery casing; a first liquid inlet is formed in the side wall of the periphery casing; the detection device assembly comprises a protective casing, a liquid level sensor, an adjusting device and a sampling detection assembly; a second liquid inlet is formed in the protective casing; the sampling detection assembly comprises a longitudinal sampling tube, a sampling connection tube and a vacuum sampling detection bottle; an electromagnetic valve is arranged at the connecting part of the longitudinal sampling tube and the sampling connection tube; the control alarm device comprises a storage battery, a controller and an alarm lamp. The sampling and detection integral device has the beneficial effects that multiple metal ions can be detected at one time, in addition, relatively accurate detection results can be obtained, and two steps of sampling and detection can be completed at one step.

Description

technical field [0001] The invention relates to the field of sampling and detection devices, in particular to an integrated sampling and detection device for soil environment detection. Background technique [0002] Excessive heavy metals will cause environmental pollution, and the accumulation effect of heavy metals in organisms will pose a potential threat to human health. [0003] With the development of the economy, harmful heavy metals (such as Zn, Cu, Pb, Cd, Cr, etc.) , people also pay more attention to the health and quality of fruits and agricultural products. The soil environment directly affects the growth and quality of plants. When heavy metals accumulate to a certain extent, they will pollute the soil, affect the growth and quality of fruit trees and agricultural products, and then cause harm to human health through the food chain. Therefore, it has certain practical significance to monitor and evaluate the content of heavy metals in soil. In the prior art, ...

AI Technical Summary

Problems solved by technology

[0004]1. There are many kinds of metal ions in the soil. The detection method in the prior art can only sample and detect one kind of metal ion at a time. When testing one by one, the detection process takes a long time and is inefficient

[0005]2. When sampling the soil when the area of ​​the measured soil layer is large, since the soil samples taken in each direction are very few, the ion concentration in the soil is between Uneven distribution in the entire measured soil layer area, using the measurement method in the prior art will lead to very inaccurate measurement results

[0006]3. In the prior art, when detecting ions in soil, sampling and detection are generally carried out step by step, and the samples need to be transported to the detection room for detection. Sampling and testing process is cumbersome
