Description

Sample preservation device for groundwater detection Technical Field The utility model relates to the field of groundwater detection, in particular to a sample storage device for groundwater detection. Background The groundwater is required to be poured into the bottle body for preservation after being sampled. For example, chinese patent CN212767719U provides a water sample preservation bottle, which comprises a glass layer and a cold storage jacket, wherein the glass layer and the cold storage jacket are sleeved outside the glass layer to form a bottle body, a bottle cap is arranged at the bottle mouth of the bottle body, and the bottle body and the bottle cap are covered by a detachable heat preservation layer. For example, in the preservation bottle in the prior art, in the detection process, samples in the bottle body need to be poured out in batches to detect different projects, and due to long-time storage of the preservation bottle, partial impurities are precipitated, so that larger errors occur in detection results of samples in each batch, and the accuracy of detection data is affected. Disclosure of utility model The utility model aims to provide a sample preservation device for groundwater detection, which solves the problems that a preservation bottle in the prior art is easy to produce precipitation when samples are stored for a long time, so that larger errors occur in detection results of samples taken out from each batch, and the accuracy of detection data is affected. In order to achieve the above object, the present utility model provides a sample storage device for groundwater detection, the sample storage device for groundwater detection includes a storage bottle, an annular supporting portion is formed at a bottom of the storage bottle, a rotating member is rotatably provided at a bottom of the storage bottle, an upper portion of the rotating member is located in the storage bottle, a lower portion of the rotating member is located in the annular supporting portion, a stirring rod located in the storage bottle is detachably provided at an upper portion of the rotating member, and a key groove is formed at a lower end surface of the rotating member. Preferably, a hole is formed at the bottom of the storage bottle, the rotating piece is rotatably clamped in the hole, and a sealing ring assembly is arranged at the contact part of the rotating piece and the hole. Preferably, a screw hole is formed in the upper end face of the rotating member, and a threaded section matched with the screw hole is formed in the lower end of the stirring rod. Preferably, the side of the storage bottle is provided with a transparent viewing window. Preferably, a cap is connected to the upper end opening of the storage bottle in a threaded manner. Preferably, the sample storage device for groundwater detection further comprises a stirring mechanism; The stirring mechanism comprises a base body, a butt joint groove is formed in the upper end face of the base body, a motor is arranged in the base body, an output shaft of the motor extends into the butt joint groove, and a key head matched with the key groove is connected.
