Description

Technical Field

[0001] This utility model relates to the field of groundwater detection technology, and in particular to a simple device for collecting water samples from different depths of boreholes. Background Technology

[0002] In geological surveys of landslide or construction sites, the stratified nature of groundwater systems, such as unconfined and confined layers, means that groundwater at different depths may originate from different aquifers, and its water quality parameters often vary significantly, which has a major impact on later construction work. Therefore, accurately collecting groundwater samples from different depths in boreholes and conducting independent analysis is a crucial step in geological surveys.

[0003] Existing groundwater sampling methods typically involve collecting water from different depths using pumps and hoses after drilling, or using samplers lowered to the corresponding depths for sampling. However, these methods generally have the following limitations: they rely on manually marked hose scales for depth positioning, usually sampling at fixed intervals of approximately 0.5-1 meters, making it difficult to accurately capture thin layers of contamination or hydrological interfaces. Furthermore, factors such as hose stretching, borehole tilting, or water flow impact can easily cause deviations between the actual sampling depth and the target depth, affecting sample representativeness; borehole sampling requires multiple people and is cumbersome. When encountering loose strata, frequent cleaning of the intake is necessary, further reducing work efficiency. Simultaneously, the complexity of manual operation increases the risk of sample failure; traditional sampling equipment is difficult to deploy in areas with poor transportation and struggles to meet the diverse needs of shallow and deep layer monitoring. Summary of the Invention The technical problem to be solved by this utility model is to provide a simple device for collecting water samples from different depths of boreholes, accurately capturing thin-layer pollution and hydrological interfaces, refining batch collection, and significantly improving the accuracy of groundwater sampling and detection; it can be directly operated manually in conjunction with shallow sampling, or it can be equipped with equipment for radial deep sampling, with visual operation, making it more accurate and convenient; the overall structure of the device is simple and reasonable, easy to manufacture and use, easy to maintain, and easy to use.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a simple device for collecting water samples from different depths of boreholes, including a sampling bucket. The sampling bucket is equipped with a traction structure. The inside of the sampling bucket is equipped with multiple sets of sample storage chambers, a distribution pump, and multiple sets of sampling heads. The multiple sets of sample storage chambers and multiple sets of sampling heads are correspondingly coordinated. Each set of sampling heads and sample storage chambers are connected to the sample storage chambers through sampling tubes and delivery tubes to form a complete passage. Each passage is controlled to open and close by multiple sets of solenoid valves in the distribution pump. A battery assembly is provided at the bottom of the sampling bucket. The battery assembly is connected to the distribution pump through a power transmission line. A control assembly that coordinates with the distribution pump is provided at the top of the sampling bucket.

Detailed Implementation

[0019] Example 1: like Figure 1-4 A simple device for collecting water samples from different depths of a borehole includes a sampling bucket 1 with a traction structure. Inside the sampling bucket 1 are multiple sets of sample storage chambers 7, a distribution pump 11, and multiple sets of sampling heads 13. The multiple sets of sample storage chambers 7 and multiple sets of sampling heads 13 are correspondingly matched. Each set of sampling heads 13 and sample storage chambers 7 are connected to the sample storage chambers 7 through sampling tubes 12 and delivery tubes 15 to form a complete passage. Each passage is controlled to open and close by multiple sets of solenoid valves in the distribution pump 11. A battery assembly 17 is provided at the bottom of the sampling bucket 1, and the battery assembly 17 is connected to the distribution pump 11 through a power transmission line 16. A control assembly 5 is provided at the top of the sampling bucket 1 to control the distribution pump 11.

[0020] In such Figure 1 and 2 In the preferred embodiment shown, the traction structure includes multiple sets of lifting rings 2 evenly distributed around the center of the sampling bucket 1 at its top, with traction ropes 3 suspended from the lifting rings 2. The traction ropes 3 are provided with stroke scales 4 to accurately indicate the depth position of the sampling bucket 1 in the borehole.

[0021] In such Figure 1 and 4 In the preferred embodiment shown, the control component 5 is equipped with an altitude measuring device 6, which can acquire the altitude information of the sampling point in real time and provide a reference for data analysis.

[0022] In such Figure 4 In the preferred embodiment shown, the sampling head 13 is provided with a filter structure 14 to filter impurities in the water, prevent clogging of the sampling tube 12 and the sample delivery tube 15, and ensure the smooth progress of the sampling process.

[0023] In such Figure 2 In the preferred embodiment shown, the sample storage chamber 7 is equipped with a pull-out box 8, which facilitates the storage and retrieval of samples and improves operational convenience.

[0024] In such Figure 3 In the preferred embodiment shown, the bottom of the sampling bucket 1 is equipped with multiple sets of cameras 9, and each camera 9 has an illumination structure 10. The cameras 9 can monitor the inside of the borehole in real time, and the illumination structure 10 provides sufficient light for the cameras 9 to ensure clear observation even in dark environments.

[0025] In such Figure 1In the preferred embodiment shown, multiple sampling heads 13 are evenly and vertically distributed from top to bottom on the side wall of the sampling bucket 1, with an appropriate distance between adjacent sampling heads 13, so as to achieve stratified sampling of groundwater at different depths.

[0026] Example 2: like Figure 1-4 The working principle of this utility model is as follows: the device is lowered into the borehole by the traction structure at the top of the sampling bucket 1. The overall depth of the device is accurately located by using the stroke scale 4 on the traction rope 3 in combination with the altitude measuring device 6 on the control component 5. At the same time, the camera 9 at the bottom of the sampling bucket 1 observes the internal environment of the borehole in real time with the assistance of the lighting structure 10, ensuring that the device is lowered stably and that the sampling head 13 is aligned with the aquifer at the target depth. Multiple sets of sampling heads 13, evenly arranged from top to bottom on the side wall of the sampling bucket 1, correspond to groundwater layers at different depths. During sampling, the solenoid valve in the distribution pump 11 is controlled by the control component 5 to selectively open the passage between the sampling head 13 at the target depth and the corresponding sample storage chamber 7. After the groundwater passes through the filter structure 14 of the sampling head 13 to filter impurities, it enters the passage through the sampling tube 12. Under the power of the distribution pump 11, the water sample is transported to the corresponding storage chamber 7 through the sample delivery pipe 15, thus completing the independent storage of the sample at that depth.

[0027] The battery assembly 17 at the bottom of the sampling bucket 1 supplies power to the distribution pump 11, control assembly 5, camera 9 and other electrical components via the power transmission line 16, ensuring that the entire device can work autonomously in the borehole without an external power source. Through the independent control of the solenoid valve, it is possible to flexibly select one or more sampling heads 13 to work simultaneously, so as to achieve synchronous or stepwise collection of water samples at different depths. After sampling is completed, the device is removed from the borehole by a traction structure, and samples from each depth are easily retrieved using the pull-out box 8 on the sample storage chamber 7 for subsequent analysis.

[0028] The beneficial effects of this utility model are: accurate capture of thin-layer pollution and hydrological interfaces, refined batch collection, and significant improvement in the accuracy of groundwater sampling and detection; it can be directly operated manually in conjunction with shallow sampling, or equipped with equipment for radial deep sampling, with visual operation, making it more accurate and convenient; the overall structure of the device is simple and reasonable, easy to manufacture and use, easy to maintain, and easy to use.
