Problems solved by technology

[0004] 1. The existing groundwater sampling device has poor sampling effect and inaccurate sampling when sampling groundwater, and cannot effectively perform layered sampling of groundwater at different depths, which is not conducive to hydrogeological investigation;
[0005] 2. When the existing groundwater sampling device samples groundwater, it cannot effectively seal the groundwater after sampling, resulting in the groundwater after sampling being easily mixed with groundwater at different depths, resulting in inaccurate sampling and affecting water samples the accuracy of the analysis results;
[0006] 3. The existing groundwater sampling device can only roughly estimate the sampling depth, but cannot accurately locate the sampling depth

Abstract

The invention discloses an automatic stratified sampling geological survey device which comprises a device body, a first servo motor and a rope lowering rack are arranged at the top end of the device body, a control panel is fixedly mounted at the top end of the rope lowering rack, and a rope lowering groove is formed in the top end of the first servo motor; a rope body is arranged in the rope lowering rack, the sampling water tank is driven by a first servo motor to sink, and in the process that the sampling water tank gradually sinks, after an elastic extrusion pad at one end of the sampling water tank is extruded by the water pressure of underground water, the sampling water tank is stressed to move rightwards; and a sampling push rod is pushed away from the interior of a push cavity groove by utilizing the push rod body, and an arc-shaped through groove is exposed out of the interior of a first sealing sleeve gasket, so that underground water with different depths is collected into a sample storage cavity through connecting pipelines by utilizing the arc-shaped through groove.

Description

technical field [0001] The invention relates to the technical field of hydrogeological survey, in particular to a geological survey device for automatic stratified sampling. Background technique [0002] Hydrogeological survey refers to the hydrogeological survey and research work to find out the hydrogeological conditions of an area. The purpose of hydrogeological survey is to grasp the cause, distribution and movement of groundwater and surface water. At present, the analysis of the cause, distribution and movement of groundwater mainly depends on the sampling of groundwater. [0003] The existing groundwater sampling devices mainly have the following problems: [0004] 1. The existing groundwater sampling device has poor sampling effect and inaccurate sampling when sampling groundwater, and cannot effectively perform layered sampling of groundwater at different depths, which is not conducive to hydrogeological investigation; [0005] 2. When the existing groundwater sam...
