Environment-friendly detection water sample storage device convenient to take

Abstract

The invention discloses an environment-friendly detection water sample storage device convenient to take. The environment-friendly detection water sample storage device convenient to take comprises astorage box, balls, a sample storage pipe and a valve plate, a refrigeration column is installed in the storage box, a storage sleeve is arranged on the outer side of the refrigeration column, the storage sleeve is also located in the storage box, the balls are arranged between the storage sleeve and the refrigeration column, the storage sleeve is connected with the refrigeration column through the balls, an inserting rod is installed at the upper end of the valve plate, a reset spring is arranged on the outer side of a supporting rod, the reset spring is located on the inner side of a limiting groove, and the supporting rod is connected with the valve plate through the reset spring. According to the environment-friendly detection water sample storage device convenient to take, a water sample can be put into the sample storage pipe to be inserted into a storage cavity to be stored, meanwhile, liquid nitrogen can be injected into the hollow refrigeration column to control the temperature in the storage box and the storage sleeve, then the water sample can be conveniently stored at a low temperature, and the condition of high-temperature evaporation of the water sample is avoided.

Description

technical field [0001] The invention relates to the technical field of environmental detection, in particular to a water sample preservation device for environmental protection detection which is convenient to take. Background technique [0002] Environmental testing, namely environmental testing and treatment, is a highly technical emerging industry. The medium objects of environmental testing can be roughly divided into water quality testing, air testing, soil testing, solid waste testing, biological testing, noise and vibration testing, electromagnetic radiation Detection, radioactivity detection, heat detection, light detection, sanitation (pathogens, viruses, parasites, etc.) detection, etc., in the process of water quality detection, it is usually necessary to sample water, so it is generally necessary to use a sample storage device, but Existing sample storage devices usually have the following problems during use: [0003] 1. Traditional water samples are simply sto...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide an easy-to-take environmental protection detection water sample storage device to solve the problem of simple storage of traditional water samples in containers, but due to various conditions, most samples The project still needs to be sent to a distant laboratory for measurement, so that the sample cannot be stored at low temperature during this process, resulting in high-temperature evaporation of water. After the traditional water sample is collected and stored, when it needs to be tested , which is not conducive to taking out the water sample from the storage device, thus affecting the normal detection experiment and reducing the efficiency of environmental protection detection
