Description

Technical Field

[0001] The utility model relates to the technical field of sewage sampling, in particular to an automatic sampler for refrigerated sample storage. Background Art

[0002] Sewage refers to water that has been polluted and has lost its original function. Due to the addition of new substances into the water or changes in external conditions, the water has deteriorated and can no longer maintain its original function. Before treating the sewage, it is generally necessary to use a water quality sampler to take samples. Whether in the field of environmental protection, sewage toxicity testing or sewage virus testing, water samples are required to be refrigerated immediately after collection. Generally, they are required to be stored at 0℃~4℃ to ensure that the physical, pathological or chemical properties of the water samples will not change, and the water samples to be tested will not deteriorate, thereby ensuring the objectivity and accuracy of water sample testing.

[0003] For example, a water quality sampler capable of refrigerating water samples, with publication number CN219935377U, comprises a sampling pump, a control unit and a sample chamber, wherein the control unit is used to control the start and stop of the sampling pump according to a sampling instruction, a refrigerating box is arranged in the sample chamber, a sample bottle is arranged in the refrigerating box, the sample bottle is connected with the sampling pump, the refrigerating box comprises a receiving groove, an inner cavity and an outer cavity arranged in sequence from the inside to the outside, the receiving groove is used to receive the sample bottle, the inner cavity and the outer cavity are independent of each other, a cold storage material is built in the inner cavity, and a heat preservation material is built in the outer cavity; the water quality sampler combines a miniaturized instrument with a water sample refrigeration function, and not only has the advantages of small size, strong portability and easy use, but also can maintain the temperature of the sampled water sample within a relatively low range within a certain period of time to meet the requirements of water sample detection.

[0004] The above prior art has obvious beneficial effects, but still has shortcomings:

[0005] In the above-mentioned prior art, a water quality sampling and refrigeration process is formed by combining a pump structure with a refrigeration box, while the sampling structure only relies on a group of sample bottles for water quality storage and sampling, and its referenceability is low. In addition, the samples are preserved only by the cold storage material in the refrigeration box, and the temperature thereof is lost. The refrigeration time is low, which is insufficient to cope with long-term sampling work and cannot ensure the stability of the collected water quality. Therefore, an automatic sampler for refrigerated sample storage is proposed. Utility Model Content

[0013] Preferably, the drainage pipe is connected to one side of the shunt pipe, and one end of the sampling pipe is arranged equidistantly along one side of the shunt pipe.

[0014] Compared with the prior art, the utility model has the following beneficial effects:
