Description

Technical Field

[0001] The utility model belongs to the technical field of pollution source sampling, in particular to a sample constant temperature storage device for pollution source sampling. Background Art

[0002] Pollution sources refer to the sources of pollutants that cause environmental pollution, usually referring to places, equipment, devices or human bodies that emit harmful substances into the environment or have harmful effects on the environment. They can be divided into natural pollution sources, atmospheric pollution sources, man-made pollution sources, industrial pollution sources, etc. In order to ensure a clean environment, it is usually necessary to control the pollution sources. In the process of controlling the pollution sources, it is necessary to sample and analyze the pollution sources to ensure efficient control of pollution sources containing different components. In the sampling process of pollution sources, since the components in some pollution sources are greatly affected by the ambient temperature, large changes in temperature may cause the inactivation and decomposition of the components. In order to ensure the accuracy of the analysis results, it is usually necessary to store the pollution source samples with constant temperature storage equipment to ensure that the composition of the samples will not change significantly. However, it still has the following disadvantages in actual use:

[0003] 1. The utility model with announcement number CN204872109U discloses a constant temperature sample storage box for field environmental monitoring sampling. The battery and the microprocessor are arranged between the ABS plastic shell and the aluminum liner of the box body. Two semiconductor cooling sheets are arranged on both sides of the box body and one side is close to the aluminum liner and the other side is close to the aluminum radiator. The aluminum radiator is exposed to the ABS plastic shell of the box body. The display / control screen is arranged on the front of the box body. The battery provides the microprocessor, the two semiconductor cooling sheets and the display / control screen to control the cooling and heating working modes of the two semiconductor cooling sheets. The display / control screen displays the real-time temperature in the box body. The constant temperature sample storage box can store samples at a constant temperature, avoiding the influence of the sample analysis results on the on-site ambient temperature on the sample, and ensuring the accuracy and precision of the monitoring structure. However, in the actual sample collection process, it is often necessary to collect samples at multiple collection points. Therefore, during the sampling process, the storage box needs to be opened and closed multiple times to store multiple samples. Opening the storage box will cause heat exchange between the environment and the storage box. The staff needs to close the storage box in time and quickly to avoid a large change in the temperature inside the storage box. The operation is time-consuming and laborious. In addition, the temperature change causes the storage box to consume more electricity to maintain a constant temperature, which increases expenses.

[0004] 2. When placing the sampling bottles in the sample constant temperature storage equipment for pollution source sampling, in order to ensure the stability of the sampling bottles and avoid the sampling bottles from tipping over and causing the samples to flow out, it is usually necessary to set up structures such as shelves and support frames to support the sampling bottles. However, different pollution sources may require sampling bottles of different sizes, and one size of support structure is difficult to accommodate sampling bottles of multiple sizes. As a result, during actual sampling, the support structure needs to be adjusted according to the size of the sampling bottle, which is time-consuming and labor-intensive. Utility Model Content
