Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring technology, and in particular to a rapid groundwater quality sampling device. Background Technology

[0002] Groundwater is water that exists in the pores of rocks below the ground surface and is an important component of water resources. Groundwater sampling is used to monitor water quality, determine whether it is polluted and the degree of pollution, and provide a basis for water resource protection and utilization. Using rapid sampling devices can shorten sampling time, improve efficiency, reduce external interference, ensure sample representativeness, and more timely and accurately reflect the true state of groundwater quality.

[0003] The working principle of rapid groundwater sampling devices varies depending on their construction. Simple devices rely on gravity, using a bottom support block to sink to the target depth. Water flow is controlled by an inlet valve to enter the sampling bottle for sampling. Automatic sampling devices with airbag pumps use an airbag pump controller to adjust the inflation and deflation of the airbag, changing the internal pressure to create suction and extract the water sample. A water level control unit monitors the water level to assist sampling, and a depth-controlled sampling system ensures sampling at the designated depth. Simultaneously, a six-parameter water quality monitoring unit analyzes the water sample in real time. Devices with drilling capabilities first use a base and lifting motor to complete the drilling, then use a suction tube and syringe to extract water samples from the bottom of the hole, achieving rapid and accurate sampling.

[0004] In existing technologies, some simple sampling devices lack a rapid recovery structure, making them susceptible to interference from environmental factors such as water flow and water pressure during sampling. This makes it difficult to accurately control the sampling depth and speed, resulting in insufficient representativeness of the water samples. Therefore, a rapid groundwater quality sampling device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a rapid groundwater sampling device, which aims to improve the problem that the existing sampling devices do not have a rapid recovery structure, are easily affected by environmental factors such as water flow and water pressure during sampling, and are difficult to accurately control the sampling depth and speed, resulting in insufficient representativeness of the water samples.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A rapid groundwater sampling device includes a base plate, two fixed plates are fixedly connected to the top of the base plate, and a fixed plate is fixedly connected to the top of each of the two fixed plates. A protective shell is fixedly connected to the front side of one of the fixed plates, a rotating rod is rotatably connected to the rear side of the protective shell, a ratchet is fixedly connected to the front side of the rotating rod, a fixed rod is fixedly connected to the inner wall of the rotating rod, and a spring is provided on the outside of the fixed rod. A moving rod is slidably connected to the top of the protective shell, a moving block is fixedly connected to the bottom of the moving rod, a pawl is rotatably connected to the left side of the moving block, and rotating columns are fixedly connected to adjacent sides of the two fixed plates. A disassembly assembly for disassembling the sampling tube is fixedly connected to the outside of the rotating column.

[0008] As a further description of the above technical solution:

[0009] The disassembly assembly includes a rope, the inside of which is fixedly connected to the outside of the rotating column. A fixed shell is fixedly connected to one side of the rope. A second spring is fixedly connected to the inner wall of the fixed shell. A fixed column is fixedly connected to the right side of the second spring. A second movable rod is slidably connected to the inner wall of the fixed shell. Two limiting blocks are fixedly connected to the outside of the second movable rod.

[0010] As a further description of the above technical solution:

[0011] A telescopic rod is fixedly connected to the bottom of the movable block, and a spring is provided on the outside of the telescopic rod;

[0012] As a further description of the above technical solution:

[0013] A guide plate is fixedly connected to the inner wall of the protective shell, and the right side of the movable block is slidably connected to the left side of the guide plate.

[0014] As a further description of the above technical solution:

[0015] The ratchet is externally engaged with the pawl, and a fixing plate is fixedly connected to the top of the moving rod.

[0016] As a further description of the above technical solution:

[0017] A rotating wheel is fixedly connected to the rear side of the rotating rod, and the outside of the rotating rod is fixedly connected to the inside of the rotating column;

[0018] As a further description of the above technical solution:

[0019] The fixed post is externally slidably connected to the inside of the fixed shell, and the right side of the fixed post is in contact with the left side of the limiting block;

[0020] As a further description of the above technical solution:

[0021] A collection tube is fixedly connected to the right side of the second movable rod, and the outside of the limiting block is slidably connected to the inside of the fixed shell.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the moving rod moves, causing the moving block to move downward, disengaging the pawl from the ratchet, which in turn causes the spring on the fixed rod to exert force, causing the fixed rod to drive the rotating column to rotate, thereby achieving rapid retrieval of the sampling device. In addition, it significantly shortens the on-site operation time, thereby improving the overall efficiency and timeliness of the sampling operation.

[0024] 2. In this utility model, the operator inserts the movable rod two into the fixed shell. After encountering the fixed column, it is rotated, causing the limiting block to be limited by the fixed plate and thus entering the limiting groove. At this time, under the action of the spring two, the limiting block is stably locked, thereby realizing the rapid installation of the sampling device. In addition, it greatly shortens the operation preparation time, thereby improving the efficiency of groundwater quality sampling. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 2 and Figure 3 This utility model provides an embodiment of a rapid groundwater sampling device, comprising a base plate 1, which serves as the foundation of the entire device, supporting and stabilizing it. Two fixing plates 2 are fixedly connected to the top of the base plate 1, and fixing discs 3 are fixedly connected to the top of each fixing plate 2. The fixing plates 2 support each other for stability. The fixing discs 3 limit the movement of the rope 14, protecting one of the fixing discs 3. A protective shell 4 is fixedly connected to the front of the fixing disc 3, protecting the internal retrieval device. A rotating rod 5 is rotatably connected to the rear of the protective shell 4, and a ratchet 6 is fixedly connected to the front of the rotating rod 5. The rotating rod 5 receives external force, causing it to rotate and rotate the ratchet 6. The inner wall of the rotating rod 5 is fixedly connected to... A fixed rod 7 is attached, and a spring 8 is provided on the outside of the fixed rod 7. A moving rod 9 is slidably connected to the top of the protective shell 4. A moving block 10 is fixedly connected to the bottom of the moving rod 9. A pawl 11 is rotatably connected to the left side of the moving block 10. A rotating column 23 is fixedly connected to the adjacent side of the two fixed discs 3. The fixed rod 7 receives the rotational force of the rotating rod 5, thereby rotating and causing the spring 8 to be compressed. The moving rod 9 receives external force, causing the moving block 10 to move and causing the pawl 11 to rotate. The pawl 11 limits the ratchet 6 to prevent the ratchet 6 from rotating back. The rotating column 23 receives the force applied by the operator, thereby rotating. A disassembly assembly for disassembling the sampling tube is fixedly connected to the outside of the rotating column 23.

[0033] Reference Figure 2 and Figure 4 The disassembly assembly includes a rope 14, which is internally fixedly connected to the outside of the rotating column 23. The rope 14 is one of the basic components of the equipment and is connected to the sampling device. A fixed shell 16 is fixedly connected to one side of the rope 14. A second spring 17 is fixedly connected to the inner wall of the fixed shell 16. A fixed column 18 is fixedly connected to the right side of the second spring 17. A second moving rod 20 is slidably connected to the inner wall of the fixed shell 16. Two limiting blocks 19 are fixedly connected to the outside of the second moving rod 20. The fixed shell 16 protects the internal limiting components and stabilizes them. The second spring 17 receives the pushing force from the fixed column 18, thereby compressing it. The second moving rod 20 receives external force and moves accordingly. The limiting blocks 19 move with the second moving rod 20 to stabilize it.

[0034] Reference Figures 1 to 3 A telescopic rod 12 is fixedly connected to the bottom of the movable block 10. A spring 13 is provided on the outside of the telescopic rod 12. Both the telescopic rod 12 and the spring 13 receive the pushing force of the movable block 10, thereby squeezing it and causing the movable block 10 to rebound. A guide plate 24 is fixedly connected to the inner wall of the protective shell 4. The right side of the movable block 10 is slidably connected to the left side of the guide plate 24. The guide plate 24 allows the movable block 10 to move linearly and stabilize it. The ratchet 6 is externally engaged with the external side of the pawl 11. The pawl 11 limits the ratchet 6 so that it cannot rotate. A fixed plate 15 is fixedly connected to the top of the movable rod 9. The fixed plate 15 receives the pushing force of the operator, thereby moving the movable rod 9. A rotating rod 5 is fixedly connected to the rear side of the rotating rod. Wheel 22 receives the rotational force from the operator, causing the rotating column 23 to rotate. The rotating rod 5 is externally fixedly connected to the inside of the rotating column 23, receiving the rotational force from the rotating column 23 and thus rotating. The fixed column 18 is externally slidably connected to the inside of the fixed shell 16, receiving the pushing force from the second spring 17 and the limiting plate, thus moving. The right side of the fixed column 18 contacts the left side of the limiting block 19. The fixed column 18 contacts the limiting block 19 under the action of the spring. The right side of the moving rod 20 is fixedly connected to the collection pipe 21. The limiting block 19 is externally slidably connected to the inside of the fixed shell 16. The collection pipe 21 is used to sample groundwater. The limiting block 19 moves with the moving rod 20 to stabilize it.

[0035] Working principle: The operator applies force to the fixed plate 15, causing it to move the moving rod 9. This causes the moving block 10 to move linearly under the action of the guide plate 24, which in turn causes the pawl 11 to rotate. This disengages the pawl 11 from the ratchet 6, allowing the spring spring 8 on the fixed rod 7 inside the rotating rod 5 to apply force, causing the fixed rod 7 to rotate. This, in turn, causes the rotating column 23 to rotate, thus allowing the sampling device to rise rapidly. This achieves rapid retrieval of the sampling device and significantly reduces on-site operation time, thereby improving the overall efficiency and timeliness of the sampling operation.

[0036] The operator pushes the second movable rod 20 into the fixed shell 16, so that the limiting plate touches the fixed plate 3, causing the second spring 17 to compress it. At this time, the operator rotates the second movable rod 20, causing the limiting plate to rotate as well. Then, the force applied to the second movable rod 20 is released, and the second spring 17 begins to release its force, causing the fixed plate 3 to apply force to the limiting plate, thus causing the limiting plate to be locked in the limiting groove. This achieves rapid installation of the sampling device, and significantly shortens the operation preparation time, thereby improving the efficiency of groundwater quality sampling.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
