Abstract
Description
Technical Field
[0001] This utility model relates to the field of groundwater sample collection technology, and in particular to a desert groundwater sample extraction device. Background Technology
[0002] Groundwater sampling is primarily used for monitoring water quality, detecting pollution sources, assessing the sustainability of groundwater resources, and analyzing hydrogeological characteristics. By collecting groundwater samples, the concentrations of harmful substances in the water, such as heavy metals, pesticides, and chemical pollutants, can be analyzed to determine whether the water quality meets drinking water or agricultural irrigation standards.
[0003] Groundwater sampling typically requires drilling equipment to open a well, penetrate the groundwater layer, and establish a water intake channel to obtain the groundwater source. Subsequently, extraction devices, such as pumps or samplers, need to be lowered into the well to ensure stable and continuous extraction of groundwater samples. This process is quite cumbersome, and in sandy soils with relatively soft geology, the multiple steps involved can easily damage the groundwater layer, adversely affecting the groundwater environment and compromising operational safety and accuracy. Utility Model Content
[0004] The technical problem this invention aims to solve is that the process of collecting groundwater samples in sandy areas is cumbersome and easily affected by external factors.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a desert groundwater sample extraction device, including a frame, a workbench fixedly connected to the center of the frame, a rotating motor fixedly installed at the bottom of the workbench, a rigid hollow extraction tube fixedly installed at the output end of the rotating motor, a conical drill bit fixedly installed at the bottom end of the hollow extraction tube, an electric chamber fixedly installed on one side of the hollow extraction tube, and a water pumping valve body connected to the hollow extraction tube fixedly installed on the inner wall of one side of the electric chamber.
[0006] As a further improvement of this utility model, push rod motors are fixedly installed at both the top and bottom of the electric chamber, and a snap-fit cover matching the water pump valve body is fixedly installed at the output end of the push rod motor.
[0007] As a further improvement of this utility model, a sealed waterproof interlayer is provided between the push rod motor and the output end, and the push rod motor is coated with a waterproof coating.
[0008] As a further improvement of this utility model, two screw holes are provided on both sides of the workbench, and bolts are fastened to the screw holes and the bolts are fastened to the frame.
[0009] As a further improvement of this utility model, the water pumping valve body is provided with multiple water pumping ports.
[0010] As a further improvement of this utility model, anti-slip pads are threadedly connected to the four corners of the bottom of the frame, and anti-slip grooves are formed at the bottom of the anti-slip pads.
[0011] The beneficial effects of this invention are as follows: By fixing a rotating motor at the bottom of the workbench, and securely attaching a detachable hollow suction tube to the motor's output end, operators can quickly change the tube to meet different sampling needs, ensuring the cleanliness and accuracy of each sample collection. A multi-port pumping valve is connected to one side of the hollow suction tube via an electric chamber, allowing groundwater samples to be collected into the tube. This ensures a smoother pumping process, stable control of the water flow rate, and prevention of sample contamination or uneven flow. Furthermore, the frame, workbench, and four anti-slip pads at the four corners of the frame's bottom ensure the stability of the drilling operation, providing robust support and preventing the equipment from shaking or tilting during drilling, thus ensuring a smooth drilling process.

It should also be understood that the term “and / or” as used herein refers to and includes one or more of the associated listed items, any or all possible combinations thereof.
[0019] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0020] This utility model provides a desert groundwater sample extraction device, including a frame 1;
[0021] As attached Figure 1 , 2 As shown in Figure 4, a workbench 2 is securely connected to the center of the frame 1. Two screw holes are opened on both sides of the workbench 2, and bolts 9 are securely connected to these holes. The bolts 9 are firmly connected to the frame 1 to reinforce the connection and ensure a tight structural fit between the workbench 2 and the frame 1. Anti-slip pads 10 are threaded onto the four corners of the bottom of the frame 1. The bottom of the anti-slip pads 10 has anti-slip grooves to increase friction with the ground and prevent the equipment from sliding or tilting.
[0022] As attached Figure 1-4 As shown, a rotary motor is fixedly installed at the bottom of the workbench 2. A rigid hollow suction pipe 3 is securely fastened to the output end of the rotary motor. The detachable hollow suction pipe 3 is firmly locked to the output end of the rotary motor. A conical drill bit 4 is fixedly installed at the bottom of the hollow suction pipe 3. An electric chamber 5 is fixedly installed on one side of the hollow suction pipe 3. A water pumping valve body 6, which communicates with the hollow suction pipe 3, is fixedly installed on the inner wall of one side of the electric chamber 5. A push rod motor 7 is fixedly installed at both the top and bottom of the electric chamber 5. A sealed waterproof interlayer is provided between the push rod motor 7 and its output end, and the push rod motor 7 is coated with a waterproof coating to prevent water samples from wetting the push rod motor 7 and damaging its internal components when it is lowered. A snap-fit cover 8 that matches the water pumping valve body 6 is fixedly installed at the output end of the push rod motor 7. After the water pumping is completed, the solenoid valve of the water pumping valve body 6 closes, and the snap-fit cover 8 is used to further ensure the airtight closure of the hollow suction pipe 3. The pumping valve body 6 is equipped with multiple pumping ports, and each pumping port uses a different solenoid valve, which allows for flexible selection of sampling flow rate and pressure to ensure accurate sample collection at different water depths.
[0023] Working Principle: In practical implementation, firstly, the frame 1 is placed on a stable ground. Then, the hollow extraction pipe 3 is securely fastened to the output end of the rotating motor at the bottom of the workbench 2. After the workbench 2 is placed in the center of the frame 1, it is securely connected to the frame 1 using bolts 9. The rotating motor is started, causing its output end to drive the hollow extraction pipe 3 and the conical drill bit at the bottom of the hollow extraction pipe 3 to rotate downwards continuously until the hollow extraction pipe 3 is pushed to the water body and then stops. After ensuring that the electric chamber 5 is submerged in water, the push rod motor 7 located at the top and bottom of the electric chamber 5 is started, causing its output end to drive the locking cover 8 to separate. After opening multiple solenoid valves on one side of the water pumping valve body 6, the water sample is extracted. Finally, the hollow extraction pipe 3, which is securely fastened to the output end of the rotating motor, is removed, and the measured water sample is obtained.
