Description

Environmental geology investigation sample strorage device Technical Field The utility model relates to the technical field of sample storage, in particular to an environmental geological investigation sample storage device. Background Environmental geological survey samples include water (surface water, groundwater, wastewater), soil and sediment, rock and mineral products (specimens, cores), biological samples and atmospheric sediment, etc., which are used mainly for detecting pollutants, assessing geologic structures and ecological risks. In order to avoid shock pollution and external temperature influence, water samples in the current environmental geological survey are usually stored in a refrigerator with a rubber positioning sleeve through a sampling bottle. Although the rubber locating sleeve can be used for self-adaptively locking sampling bottles with different specifications, the connection tightness between the rubber locating sleeve and the sampling bottle is correspondingly improved along with the increase of the diameter of the sampling bottle, and the tight contact can obstruct the cold air circulation in the refrigerator, so that the condition of uneven temperature distribution in the refrigerator is caused. Disclosure of utility model Based on the above, it is necessary to provide an environmental geological survey sample storage device for solving the problem that the refrigerating storage effect is poor. An environmental geological survey sample storage device, comprising: the refrigerator comprises a refrigerator, wherein an ice bag placing cavity is formed in the inner bottom wall of the refrigerator; The positioning storage mechanism comprises a mounting frame fixedly connected to the inside of the refrigerator, aligned placement holes are formed in the top and bottom ends of the mounting frame, an adjusting screw is connected to the top of the mounting frame in a rotating mode, the rod portion of the adjusting screw penetrates through the inner side of the mounting frame, a mounting frame aligned to the placement holes is connected to the rod portion of the adjusting screw in a threaded mode, and positioning elastic pieces which are annularly distributed around the axis of the placement holes are fixedly connected between the mounting frame and the placement holes.
