Sample concentrating and sampling device for hydraulic ring geological engineering survey

Abstract

The invention discloses a sample concentration sampling device for hydraulic ring geological engineering survey, which comprises a sampling box, a concentration quantification mechanism is installed in the sampling box, the concentration quantification mechanism comprises a concentration box fixedly connected to the top in the sampling box, and the inner wall of the concentration box is in sealed sliding connection with a sliding plate. A first spring is fixedly connected to the inner bottom of the concentration box, the upper end of the first spring is fixedly connected with the sliding plate, a sampling pipe is fixedly connected to the upper end of the concentration box, a vortex pipe is fixedly connected to the lower end of the sampling box, a high-pressure air inlet pipe is fixedly connected to the lower end of the vortex pipe, and an air inlet groove is formed in the lower end of the sampling box. According to the concentration quantification mechanism, after a water resource sample in the concentration box is concentrated every time, the amount of the remaining concentrated samples is the same, then the amount of the concentrated samples is the same every time, quantitative sampling is achieved, and the situation that due to the different sampling amounts, the sample analysis contrast is poor, and the sampling time is shortened is avoided. And the analysis result is inaccurate.

Description

technical field [0001] The invention relates to the technical field of sample sampling devices, in particular to a sample concentration and sampling device for hydraulic and environmental geological engineering surveys. Background technique [0002] Hydraulic and environmental geology is the abbreviation of hydrogeology, engineering geology and environmental geology. It mainly surveys the geological conditions of groundwater resources, engineering construction and natural environment, mainly through sampling, testing and analysis of water resources and soil. [0003] In the existing hydro-environmental geological engineering survey process, the water resource samples of the on-site environment are first collected, and then the water resource samples are concentrated and sampled. After the device concentrates the samples, the sampling operation is performed manually. Due to the large error in manual sampling, it cannot be guaranteed that the amount of samples drawn each time ...

[0003] In the existing hydraulic and environmental geological engineering survey process, the water resource samples of the site environment are first collected, and then the water resource samples are concentrated and sampled. However, the existing concentrated sampling of samples for hydraulic and environmental geological engineering survey After the device concentrates the sample, the sampling operation is performed manually. Due to the large error in manual sampling, it cannot be guaranteed that the amount of sample drawn each time is the same, and quantitative sampling cannot be performed, which will affect the quality of the samples. Analytical contrast, reducing the accuracy of sample analysis
