An environmental geological exploration sample storage device

Abstract

The invention provides a storage device for environmental geological survey samples, which includes a plurality of storage tanks; each storage tank includes an outer tank and an inner tank arranged in the outer tank; a movable piston is arranged inside the inner tank; the top of the inner tank and the outer tank A sampling tube passes through and is fixed; one end of the two screw rods passes through the top of the inner tank and the outer tank respectively, and a piston plate is fixed at the end, and the piston plate slides and fits with the inner wall of the inner tank; the upper part of each screw rod is threaded with a nut; The limit device includes a baffle and two limit springs; one end of the two limit springs is respectively fixed at the ends of the two circular grooves, and the other end is fixedly connected to the top of the baffle; the exhaust device includes a top plate, an electromagnet and two support rods; the piston plate is provided with a second through groove, and the outer ring of the second through groove is fixed with an iron ring; one end of the two support rods is fixed at both ends of the top plate, the other end passes through the electromagnet, and is connected with the piston Fixed connection at the top of the board. The device seals and stores the samples in a fixed manner through a storage box combined with a storage tank.

Description

technical field [0001] The invention relates to the technical field of survey sample storage, in particular to a storage device for environmental geological survey samples. Background technique [0002] Geological exploration can be understood as geological work in a broad sense. It is based on the needs of economic construction, national defense construction, and scientific and technological development, using geological exploration methods such as surveying and mapping, geophysical prospecting, geochemical prospecting, drilling, pit exploration, sampling testing, and geological remote sensing. , for the investigation and research of geological conditions such as rocks, stratum structures, minerals, groundwater, and landforms in a certain area. In the process of environmental geological exploration, it is necessary to use a sample storage device to store the obtained samples. [0003] The existing storage device stores solid samples and liquid samples separately, and stores...

Problems solved by technology

[0003] The existing storage device stores solid samples and liquid samples separately, and stores them in simple packaging. However, this storage method makes solid samples easy to collide with each other and cause damage. In addition, the source of liquid samples and solid samples is underground, which has a certain storage capacity. temperature requirements, and is easily oxidized by air, for this reason, the present invention proposes a new environmental geological survey sample storage device
