Description

Technical Field

[0001] The utility model relates to the technical field of groundwater sampling, in particular to a groundwater sampling device. Background Art

[0002] Geological exploration refers to the activity of investigating and studying geological information such as rocks, minerals, geological structures, and groundwater on the earth's surface and underground. The main purpose of geological exploration is to obtain geological information and provide a scientific basis for mineral exploration, geological disaster prevention, and land use planning. Among them, groundwater sampling is a very important task. Through sampling and analysis of groundwater, we can understand the nature, quality, and distribution of groundwater, and provide important reference data for geological exploration.

[0003] In the prior art, there is a patent with application number CN202322402513.2, which provides a portable groundwater sampler, including a sampling bottle, the sampling bottle including a bottle body, a cap and a connecting part, a counterweight cone is threadedly connected to the bottom of the bottle body, and a connecting shaft is arranged above the counterweight cone. When in use, the sampling bottle is sent into the groundwater source by a reel machine, and the bottle mouth of the sampling bottle is always kept upward. When the sampling bottle is immersed in water, the water flows into the sampling bottle through the bottle mouth on the connecting part of the sampling bottle. When the sampling bottle is filled with water, the sampling bottle is pulled out of the groundwater source and returned to the ground by a portable integrated reel machine. After the staff tightens the bottle cap and the connecting part, the sampling bottle is moved to the vicinity of the water quality sample storage container, the bottle cap is opened, and the water quality sample therein is poured into the water quality sample storage container to complete a sampling.

[0004] However, the above patent still has the following deficiencies during use:

[0005] When sampling groundwater, it is often necessary to sample and analyze water at different depths, because groundwater at different depths may have different hydrogeological characteristics and water quality characteristics; and when the sampling device provided by the above patent retracts the sampling bottle, the mouth of the sampling bottle is in an open state, and during the process, water at different depths will be mixed in the sampling bottle, resulting in inaccurate analysis results.

[0039] Among them, the control module generally includes a motor controller, a communication device (a communication device used to achieve remote control, which can be a wireless remote control, a Wi-Fi module, a Bluetooth module or other types of communication devices. The communication device is used to transmit control instructions to the motor controller), a controller (a controller used to send control instructions to the motor controller, which can be a mobile phone app, computer software or an automation system. The controller communicates with the motor controller through the communication device to achieve remote control) and a power supply (provides power supply for the motor and the motor controller to ensure the normal operation of the motor). The technology of remotely controlling the motor is a common existing technology.

[0040] The mounting seat 9 is a hollow cylindrical structure, and an internal thread is arranged on the inner wall of the mounting seat 9 .

[0041] The bottle body 7 is a columnar structure that matches the mounting seat 9, and an external thread that cooperates with the mounting seat 9 is provided on the outer periphery of the bottle body 7 near the bottom. The threaded mounting arrangement of the mounting seat 9 and the bottle body 7 allows the sampling bottle to be quickly assembled and disassembled, thereby improving the convenience of use of the utility model.

[0042] The bottle cap 8 includes a cover body 16 threadedly connected to the bottle body 7 , and a through hole 17 coaxial with the cover body 16 is opened and closed at the top of the cover body 16 .

[0043] The closing assembly is used to close the through hole 17, and the closing assembly includes a mounting plate 20 coaxially arranged in the cover body 16, a plurality of connecting rods 21 are fixedly connected between the periphery of the mounting plate 20 and the inner wall of the cover body 16, and an elastic support rod 22 coaxial with 6 is fixedly installed on the top surface of the mounting plate 20;

[0044] A baffle 18 coaxial with the rubber plug 19 is fixedly mounted on the telescopic end of the elastic support rod 22 . The diameter of the baffle 18 is larger than the diameter of the through hole 17 . Under the elastic support of the elastic support rod 22 , the top surface of the baffle 18 is in compression contact with the inner top surface of the cover body 16 .

[0045] The switch mechanism includes a rotating shaft 4 rotatably mounted at the center of the top surface of the mounting plate 1, the bottom end of the rotating shaft 4 rotates through the mounting plate 1 to the cavity 15, and is fixedly connected to the output shaft end of the motor 14;

[0046] An extension plate 10 vertically arranged with respect to the rotation shaft 4 is fixedly mounted on the top of the rotation shaft 4 , and a mounting block 11 located above the cover 16 is fixedly mounted on the end of the extension plate 10 away from the rotation shaft 4 , and a switch assembly 3 is mounted on the bottom surface of the mounting block 11 .

[0048] When the utility model is in use:

[0049] The end of the rope 6 away from the connecting block 5 is fixed to the external retractable device. When sampling, the rope 6 is released through the retractable device. Under the gravity of the counterweight block 2, the device body will sink in the water. After reaching the specified depth position, the device is remotely controlled to perform sampling.

[0050] Specifically, in this embodiment, five mounting seats 9 are taken as an example. In the initial state, the extension plate 10 is located in the middle position between two adjacent mounting seats 9, and the height of the lower end of the pressing plate 12 is lower than the height of the baffle 18; when sampling, the control motor 14 drives the rotating shaft 4 to rotate thirty-six degrees counterclockwise. At this time, the mounting block 11 is located directly above a bottle cap 8, and the lower end of the pressing plate 12 is squeezed and contacted with the baffle 18 under the elastic force of the spring 13, so that the elastic support rod 22 shrinks to a certain extent. At this time, there is a gap between the baffle 18 and the inner top surface of the cover body 16, and water can enter the sampling bottle through the gap; then the control motor 14 drives the rotating shaft 4 to rotate thirty-six degrees. At this time, the pressing plate 12 is separated from the cover body 16, and the baffle 18 is reset to a state of closing the through hole 17 under the elastic force of the elastic support rod 22, thereby avoiding water at different depths from mixing into the sampling bottle when the device is lifted.

[0051] Therefore, in the utility model, the switch mechanism and the sealing component in the bottle cap 8 are arranged in cooperation to keep the sampling bottle in a closed state after sampling is completed, thereby avoiding mixing of water in the sampling bottle, thereby improving the accuracy of subsequent detection and analysis results.

[0052] In addition, the utility model is provided with multiple mounting seats 9, so that multiple groups of sampling bottles can be installed at the same time. Combined with the rotation of the remote control switch assembly, the opening and closing of multiple sampling bottles can be controlled counterclockwise in the water, so as to perform continuous sampling. The utility model can perform sampling at different depths as needed during a single sinking process, thereby improving the practicality of the utility model.

[0053] Embodiment 2:

[0054] See also Figure 6On the basis of Example 1, a rubber plug 19 matching the through hole 17 is fixedly installed on the top surface of the baffle 18. The setting of the rubber plug 19 can improve the sealing between the baffle 18 and the inner top surface of the cover 16, thereby reducing the possibility of water at different depths being mixed into the sampling bottle, and further improving the accuracy of subsequent analysis results.

[0055] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model.
