Problems solved by technology

[0005] 1. The airtight performance of the existing groundwater sampling devices is poor, resulting in the obtained water samples often including water bodies that do not reach the specified water level, resulting in inaccurate data for subsequent water sample testing
[0006] 2. Existing groundwater sampling devices can only roughly estimate the sampling depth, but cannot accurately locate the sampling depth
[0007] 3. The existing groundwater sampling device cannot realize the continuous collection of groundwater at different depths, and the sampling efficiency is low
[0008] 4. The existing groundwater sampling device has poor stability during the sampling process, which makes groundwater sampling more difficult

Embodiment 1

[0092]Such asfigure 1 As shown, the present invention has a hydrological geological survey automatic sampling device including sampling boxes 1, sampling box guiding mechanism, sampling box lifting mechanism, sampling box positioning mechanism, sampling mechanism, and host machine.

[0093]The role of the sampling box 1 is to achieve the installation of the sampling mechanism.

[0094]Such asfigure 2 As shown, the sampling case 1 includes a tape cap 2, a casing body 3, and a casing 4.

[0095]The box body 3 is square, such asfigure 1 Indicated. The box body 3 has four sidewalls, defining the direction toward the outer direction of the paper, respectively, in the left and right side walls of the casing body 1, one guide plate, such as the guide plate 5.

[0096]Taking one of the guide plates 5 as an example, a guiding hole 6 is provided on each guide plate 5 for easy directions.

[0097]A sampling hole 7 is also provided on the front side wall of the casing body 1, and the number of sample holes is...

Embodiment 2

[0176]In this first embodiment, a hydrological geological surveying automatic sampling method is based on the hydrological geological surveys, such as the hydrological geological survey, andFigure 9As shown, it includes the following steps:

[0177]I. Each mechanism of the automatic sampling device for hydrogeneous geological surveys in sequence is assembled, and the assembly of the device is completed;

[0178]II. The host computer controls the speed reduction motor 27 rotation, the cable disk 25 automatically wires, at this time, under the action of the guide rod 10, the sampling case is stable, and the sampling case positioning mechanism is sampled in real time in the decline in the decline. Falling height.

[0179]Iii. When the sample case 1 drops to a predetermined depth position, the host computer controls the speed reduction motor 27 to stop the action. At this time, the sample case 1 exactly stops at a certain depth position.

[0180]IV. Samples in the sampling box 1 action, and automat...

Abstract

The invention belongs to the technical field of hydrogeological survey, and specifically discloses an automatic sampling device for hydrogeological survey. The device uses a sampling box lifting mechanism to realize the lifting and lowering operation of the sampling box. The box guide mechanism realizes the guidance of the sampling box to ensure the stability of the sampling box during the sampling process. At the same time, the sampling box positioning mechanism is used to realize the accurate position positioning of the sampling box, which is convenient for reaching the specified depth for groundwater sampling; After reaching the specified depth, the sampling mechanism in the sampling box is used to realize the sampling of groundwater. Since there are multiple sampling containers in the present invention, it is beneficial to realize continuous sampling of groundwater at different depths. Through reasonable design, the invention is beneficial to realize continuous automatic sampling of groundwater at different depths, and is beneficial to improving sampling precision and stability, and ensuring the accuracy of sampling results.

Description

Technical field[0001]The present invention belongs to the field of geological surveys, and more particularly to an automatic sampling device for hydrogemic geological surveys.Background technique[0002]Hydroological geological surveys refer to hydrogeological investigation and research on hydrological geological conditions in a region, and the purpose of hydrogeological surveys is to master the causes, distribution and movement of groundwater and ground water.[0003]At present, the analysis of groundwater is analyzed, the analysis of its motion laws, mainly depends on the sampling of groundwater.[0004]Existing groundwater sampling devices, most of which are simpler, and most of the need to complete the groundwater sampling operation by manual control. Summary, existing underground water sampling devices mainly have the following technical issues:[0005]1. The existing ground water sampling device is poorly comprehensively, causing the obtained water samples, which often includes a wate...
