Description

Technical Field

[0001] This utility model relates to the field of groundwater sampling technology, specifically a groundwater pollution remediation sampling device. Background Technology

[0002] In groundwater pollution investigation and remediation projects, obtaining representative groundwater samples is a crucial prerequisite for assessing the extent of pollution, developing remediation plans, and verifying the effectiveness of remediation.

[0003] Current sampling devices mostly use rope or manual lifting samplers, which are prone to shaking and deviation during the descent, making it difficult to accurately reach the target aquifer. This results in water samples being mixed with upper or lower water bodies, leading to poor representativeness. Furthermore, after sampling, samples often need to be transferred to containers on-site, which can easily lead to volatilization, oxidation, or the introduction of impurities. In addition, most of them lack integrated filtration and immediate sealing functions. Therefore, we propose a groundwater pollution remediation sampling device. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: This utility model discloses a groundwater pollution remediation sampling device, comprising a movable base, a sliding frame fixedly connected to one side of the movable base, a protective box provided on one side of the sliding frame, a fixed rod fixedly connected to the bottom of the protective box, a sliding rod slidably connected to the outer periphery of the fixed rod, a collection box fixedly connected to the bottom of the sliding rod, a servo motor fixedly installed on one side inside the protective box, a lead screw driven by a coupling at the output end of the servo motor, a fixed frame fixedly connected inside the sliding rod, and one side of the fixed frame threadedly connected to the outer periphery of the lead screw.

[0005] As a preferred embodiment of this utility model, a geared motor is fixedly installed at the top center end of the fixed rod, and a cross-shaped limiting rod is driven to the output end of the geared motor through a coupling. A sleeve is slidably connected to the outer periphery of the cross-shaped limiting rod, and the bottom of the sleeve is rotatably connected to the inner bottom wall of the sliding rod.

[0006] As a preferred embodiment of this utility model, the inner wall of the collection box is rotatably connected to a bevel gear, and the upper outer end of the bevel gear is meshed with a bevel gear. The top of the bevel gear is fixedly connected to the bottom of the sleeve through a connecting column.

[0007] As a preferred embodiment of this utility model, the inner wall of the collection box is rotatably connected to a bevel gear, and the upper outer end of the bevel gear is meshed with a bevel gear. The top of the bevel gear is fixedly connected to the bottom of the sleeve through a connecting column.

[0008] As a preferred embodiment of this utility model, a protective net is threadedly connected to one end of the collection box, a filter screen is fixedly connected inside one end of the collection box, and a liquid storage box is threadedly connected to the center end of the bottom of the collection box.

[0009] As a preferred technical solution of this utility model, a rotary motor is fixedly installed on the top of the sliding frame, and the output end of the rotary motor is connected to a lead screw through a coupling. A threaded block is threadedly connected to the outer circumference of the lead screw, and one side of the threaded block is fixedly connected to the protective box.

[0010] As a preferred technical solution of this utility model, the outer walls of the cross-shaped limiting rod are provided with limiting strips on both sides, and the inner wall of the sleeve is provided with a groove that cooperates with the limiting strips.

[0011] The beneficial effects of this utility model are: This groundwater pollution remediation sampling device uses a rotary motor to drive a vertical screw, which in turn drives the entire sampling mechanism to rise and fall smoothly. It can accurately deliver the collection box to the target aquifer depth, avoiding the swaying and positioning deviation of the traditional rope lowering method, and improving the representativeness of the samples. This groundwater pollution remediation sampling device, after the collection box reaches the predetermined depth, first starts the reduction motor to push the piston inward, and discharges the original air or residual liquid in the box, effectively preventing the backflow of mud and sand from the well wall and polluted water from the upper layer, ensuring that the collected sample is an in-situ groundwater sample from the target layer. This groundwater pollution remediation sampling device uses a protective net at the inlet to intercept large particulate impurities and is equipped with a high-precision filter inside to effectively remove suspended solids, protect the piston mechanism, and improve detection accuracy. This utility model has a simple and reasonable structure, novel design, and is easy and convenient to operate, and has high practical value. Attached Figure Description

[0014] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0015] Example: Figures 1-5 As shown, this utility model discloses a groundwater pollution remediation sampling device, including a movable base 1. A sliding frame 2 is fixedly connected to one side of the movable base 1. A protective box 3 is provided on one side of the sliding frame 2. A fixed rod 4 is fixedly connected to the bottom of the protective box 3. A sliding rod 5 is slidably connected to the outer periphery of the fixed rod 4. A collection box 6 is fixedly connected to the bottom of the sliding rod 5. A servo motor 7 is fixedly installed on one side inside the protective box 3. The output end of the servo motor 7 is driven by a lead screw 8 through a coupling. A fixed frame 9 is fixedly connected inside the sliding rod 5, and one side of the fixed frame 9 is threadedly connected to the outer periphery of the lead screw 8.

[0016] The top center of the fixed rod 4 is fixedly installed with a geared motor 10. The output end of the geared motor 10 is connected to a cross-shaped limiting rod 11 through a coupling. A sleeve 12 is slidably connected to the outer periphery of the cross-shaped limiting rod 11, and the bottom of the sleeve 12 is rotatably connected to the inner bottom wall of the slide rod 5. The geared motor 10 drives the sleeve 12 to rotate through the cross-shaped limiting rod 11, and transmits the power to the sampling mechanism through the bevel gear 14 and the conical gear 13.

[0017] The inner wall of the collection box 6 is rotatably connected to a bevel gear 13, and the upper outer side of the bevel gear 13 is meshed with a bevel gear 14. The top of the bevel gear 14 is fixedly connected to the bottom of the sleeve 12 through a connecting post 15.

[0018] The collection box 6 has a fixed plate 16 fixedly connected to one side of the inside. A piston 17 is slidably connected inside the fixed plate 16. A cylinder 18 is fixedly connected to one side of the piston 17. A threaded rod 19 is threadedly connected to one end of the cylinder 18. One end of the threaded rod 19 is fixedly connected to a bevel gear 13. The rotation of the bevel gear 13 drives the threaded rod 19 to rotate, causing the cylinder 18 to push the piston 17 to reciprocate within the fixed plate 16.

[0019] The collection box 6 has a protective net 20 threadedly connected to one end, a filter screen 21 fixedly connected inside one end of the collection box 6, and a liquid storage box 22 threadedly connected to the center of the bottom of the collection box 6. The liquid storage box 22 is used to seal and preserve the collected water sample for subsequent testing.

[0020] The top of the sliding frame 2 is fixedly equipped with a rotary motor 23. The output end of the rotary motor 23 is connected to a lead screw 24 through a coupling. The outer circumference of the lead screw 24 is threaded with a threaded block 25, and one side of the threaded block 25 is fixedly connected to the protective box 3. When the rotary motor 23 drives the lead screw 24 to rotate, the protective box 3, the fixed rod 4, the sliding rod 5 and the collection box 6 can be driven to rise and fall vertically along the sliding frame 2 as a whole, so as to achieve precise adjustment of the sampling depth.

[0021] The cross-shaped limiting rod 11 has limiting strips on both sides of its outer wall, and the inner wall of the sleeve 12 has a groove that cooperates with the limiting strips. The groove on the inner wall of the sleeve 12 that cooperates with the limiting strips ensures that the sleeve 12 can reliably transmit rotational torque when it rises and falls with the slide rod 5.

[0022] Working Principle: In use, the device is first transported to the groundwater sampling point via the mobile base 1. The rotary motor 23 is started, driving the vertically mounted lead screw 24 to rotate. This causes the threaded block 25 and its fixed protective box 3 to move downwards along the sliding frame 2, thus pushing the entire sampling mechanism, including the fixed rod 4, sliding rod 5, and collection box 6, to descend synchronously until the collection box 6 reaches the target aquifer depth. During the descent or after reaching the predetermined depth, the reduction motor 10 is started, its output driving the cross-shaped limiting rod 11 to rotate. Since the cross-shaped limiting rod 11 and the sleeve 12 are engaged by a limiting strip and a slot, the rotational power is transmitted through the sleeve 12 and connecting column 15 to the bevel gear 14, which in turn drives the bevel gear 13 to rotate. The bevel gear 13 drives the threaded rod 19 fixed to it to rotate, causing the cylinder 18 to push the piston 17 to move. This allows the piston 17 to separate from the fixed plate 16, allowing groundwater to pass through the protective net 20 and filter screen 21 into the collection box 6, completing the in-situ sampling. After sampling is completed, the reduction motor 10 rotates in the reverse direction, causing the piston 17 to engage with the fixed plate 16, thus completing the closure and preventing the outside air from reacting with the groundwater. Finally, the rotary motor 23 reverses, and the lead screw 24 drives the sampling mechanism to rise and reset, rotating to remove the liquid storage box 22 for testing.
