Soil sample preservation device

Technical Field

Background

Environmental monitoring refers to the qualitative, quantitative and systematic identification and testing of the composition of substances in the environment by using various technical means. In practice, environmental quality is typically monitored by taking representative samples, such as soil samples and water samples. These samples typically need to be placed in sample tubes for storage and the sample tubes placed in sample boxes for transport. To facilitate placement of the sample tubes, designers typically design a plurality of storage slots in the sample box for storing the sample tubes. And to facilitate sorting of the sample tubes, one storage tank is usually only capable of holding one sample tube, so that the number of sample tubes stored per sample tank is determined. In the actual use process, because the soil sample collecting place is usually in the field, the collector generally cannot carry a large number of sample boxes in consideration of various reasons such as transportation, transportation and the like, so that when the amount of the sample to be collected is more than the estimated amount, the sample boxes cannot store redundant sample tubes. At this point, the collector may use a bag or other box to store the excess sample tubes. However, in the process of transportation, since the bag and other boxes are only temporarily used for storing the sample tubes, the structure of the sample tubes is not fixed, so that the sample tubes collide with each other in the process of transportation, and then are damaged, so that soil samples are scattered, and further, the subsequent detection test cannot be performed, so that the problem needs to be solved.

The body between the intersection point of the elastic band 12 and the fixed point and the cavity wall between the two fixed points enclose an elastic clamping cavity for clamping the sample tube. The sample tube containing the soil sample is held in the elastic holding cavity. Guide grooves 14 are arranged on the other three sides of the storage chamber. The wire groove extends along the circumferential direction of the storage chamber, and the guide block 121 is slidably disposed in the guide groove 14. The cross section of the guide groove 14 is T-shaped, and the guide block 121 is also designed into a corresponding T-shaped block structure, so that the guide block 121 cannot slide out of the guide groove 14.
