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 as figure 1 As shown, the present invention relates to an automatic sampling device for hydrogeological survey, which includes a sampling box 1, a sampling box guiding mechanism, a sampling box lifting mechanism, a sampling box positioning mechanism, a sampling mechanism and a host computer.

[0093] The function of the sampling box 1 is to realize the installation of the sampling mechanism and the like.

[0094] Such as figure 2 As shown, the sampling box 1 includes a box top cover 2 , a box body 3 and a box bottom cover 4 .

[0095] The box body 3 is square, such as figure 1 shown. The box body 3 has four side walls, and the direction toward the outside of the paper is defined as the front. Then, a guide plate, such as a guide plate 5 , is provided on the left and right opposite side walls of the box body 1 .

[0096] Taking one of the guide plates 5 as an example, each guide plate 5 is provided with a guide hole 6 to facilitate the realization of the guide ...

Embodiment 2

[0176] Present embodiment 2 has described a kind of automatic sampling method for hydrogeological survey, and this automatic sampling method is based on the automatic sampling device for hydrogeological survey mentioned in above-mentioned embodiment 1, as Figure 9 As shown, it includes the following steps:

[0177] I. Assemble each mechanism of the automatic sampling device for hydrogeological investigation in turn, and complete the assembly of the device;

[0178] II. The upper computer controls the rotation of the deceleration motor 27, and the cable reel 25 automatically unwinds the cable. At this time, under the action of the guide rod 10, the sampling box steadily descends. During the descent, the sampling box positioning mechanism monitors the sampling box 1 in real time. drop height.

[0179] III. When the sampling box 1 drops to the predetermined depth position, the host computer controls the deceleration motor 27 to stop, and at this time, the sampling box 1 stops p...

Abstract

The invention belongs to the technical field of hydrogeological survey, and particularly discloses an automatic sampling device for hydrogeological survey. According to the device, a sampling box bodylifting mechanism is used for realizing lifting and descending operations of a sampling box body; in the descending process of the sampling box body, a sampling box body guiding mechanism is used forguiding the sampling box body so as to ensure the stability of the sampling box body in the sampling process, and meanwhile, a sampling box body positioning mechanism is used for realizing accurate position positioning of the sampling box body, so that underground water can be conveniently sampled at a specified depth; and when a specified depth is reached, sampling of underground water is realized by utilizing the sampling mechanism in the sampling box body; due to the fact that the number of sampling containers is multiple, continuous sampling of underground water at different depths can beachieved; through reasonable design, continuous and automatic sampling of underground water at different depths is facilitated; the sampling precision and stability are improved; and the accuracy ofa sampling result is ensured.

Description

technical field [0001] The invention belongs to the technical field of geological survey, in particular to an automatic sampling device for hydrogeological survey. 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. [0003] At present, the analysis of the cause, distribution and movement of groundwater mainly depends on the sampling of groundwater. [0004] Most of the existing groundwater sampling devices have relatively simple structures, and most of them need to be manually controlled to complete the groundwater sampling work. To sum up, the existing groundwater sampling device mainly has the following technical problems: [0005] 1. The airtight performance of the existing groundwater sampling devices is poor, resulting in the obtained wate...
