Description

Technical Field

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

[0002] In the prior art, such as the "Groundwater Sampling Device" in Chinese Patent No. CN220751686U, a supporting base plate is provided. The top of the supporting base plate has a through hole and a U-shaped fixing frame. A servo motor is fixedly installed on the right side of the U-shaped fixing frame. Rope-taking rollers are rotatably mounted on the inner walls of both sides of the U-shaped fixing frame via bearings. A steel wire rope is wound around the outer side of the rope-taking roller. A waterproof cylinder is fixedly installed at the beginning of the steel wire rope. A restraint mechanism is provided below the rope-taking roller. This groundwater sampling device thus achieves the function of controlling the steel wire rope... The purpose of effective constraint is to ensure the relative stability of the wire rope during its descent, effectively preventing excessive vibration and facilitating subsequent sampling operations. It also ensures the progress of groundwater sampling. However, the sampling device requires a support mechanism for support and fixation, making each sampling process particularly cumbersome. Not only does it need to be positioned and fixed, but the sampling mechanism also needs to be aligned with the ground cavity, which is quite complicated. While ropes can pull and tug on the sampling mechanism, existing devices are too cumbersome. Therefore, a solution is needed to address these issues. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies. Existing groundwater sampling devices require a support mechanism for support and fixation, making each sampling process particularly cumbersome. This not only requires positioning and fixing but also aligning the sampling mechanism with the ground cavity, which is quite complicated. However, ropes can be used to pull and move the sampling mechanism, making the existing device cumbersome. Therefore, this invention provides a groundwater sampling device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a groundwater sampling device, comprising a handle, a cable winding mechanism fixedly connected to the bottom of the handle, a sampling mechanism fixedly connected to the bottom of the cable winding mechanism, the cable winding mechanism comprising a support, the top of the support fixedly connected to the bottom of the handle, a shaft rotatably connected to the inner wall of the support, a winding disc fixedly sleeved on the outer surface of the shaft, a rope wound around the outer surface of the winding disc, a rotating plate fixedly connected to one end of the shaft, a rotating handle rotatably connected to one side of the rotating plate, two fixed frames fixedly connected to one side of the support, a rotating ring provided on the outer surface of the fixed frames, and a sampling mechanism comprising a fixed shell, a support ring fixedly connected to one side of the fixed shell, the outer surface of the support ring being fixedly connected to one end of the rope.

[0005] In a preferred embodiment, an arc-shaped shell is slidably connected to the inner wall of the fixed shell, and a lead block is fixedly connected to one side of the arc-shaped shell.

[0006] In a preferred embodiment, two semi-rings are fixedly connected to the outer surfaces of the fixed shell and the arc-shaped shell, and two threaded grooves are formed between the outer surfaces of the fixed shell and the arc-shaped shell, with threaded sleeves fitted on the outer surfaces of the threaded grooves.

[0007] In a preferred embodiment, a first curved plate is fixedly connected to the inner wall of the fixed shell, and a second curved plate is fixedly connected to the inner wall of the arc-shaped shell.

[0008] In a preferred embodiment, a needle tube is slidably connected to the inner wall of the fixed shell, a needle tip is fixedly connected to the bottom of the needle tube, the bottom end of the needle tip slides through to the outside of the fixed shell, a piston rod is slidably connected to the inner wall of the needle tube, and two grooves are formed on the outer surface of the piston rod.

[0009] In a preferred embodiment, an electric push rod is fixedly connected to the inner top surface of the fixed shell, and a slide is fixedly connected to one end of the electric push rod. The inner wall of the slide is slidably connected to the inner wall of the groove.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] This invention uses a bracket for positioning and fixation, a throttle handle to provide the force source, and the throttle handle drives the rotating plate to rotate, which in turn drives the winding reel to rotate via the shaft. The clockwise and reverse rotation of the rotating plate allows the rope on the winding reel to be wound up and down, thereby moving the sampling mechanism. Two rotating rings can regulate the rope released from the winding reel, making the winding up and down more neat and fixing the winding up and down position points, thus making the winding up and down more stable. The threaded groove and threaded sleeve cooperate to fix the fixed shell and the arc-shaped shell, and the cooperation of the threaded groove and threaded sleeve allows for... The design facilitates the removal and installation of the fixed shell and the arc-shaped shell, increasing their ease of assembly and disassembly. A semi-ring is used to limit the threaded sleeve, and the first and second curved plates can limit and fix the needle tube, preventing it from moving after the arc-shaped shell is installed. The electric push rod can then retract to move the piston rod, thereby extracting water from the area. After the arc-shaped shell is removed, further retraction of the electric push rod will drive the needle tube and needle into the interior of the fixed shell. Then, sliding will allow the needle tube, needle, and piston rod to be removed, facilitating the extraction of the sample from inside the needle tube. Attached Figure Description

[0021] 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.

[0022] Example 1

[0023] like Figure 1-4As shown, this utility model provides a technical solution: a groundwater sampling device, including a handle 1, a cable winding mechanism 2 fixedly connected to the bottom of the handle 1, a sampling mechanism 3 fixedly connected to the bottom of the cable winding mechanism 2, the cable winding mechanism 2 including a bracket 21, the top of the bracket 21 fixedly connected to the bottom of the handle 1, a shaft rotatably connected to the inner wall of the bracket 21, a winding disc 22 fixedly sleeved on the outer surface of the shaft, a rope 25 wound on the outer surface of the winding disc 22, a rotating plate 23 fixedly connected to one end of the shaft, a rotating handle 24 rotatably connected to one side of the rotating plate 23, two fixed frames 26 fixedly connected to one side of the bracket 21, a rotating ring 27 provided on the outer surface of the fixed frame 26, and a sampling mechanism 3 including a fixed shell 31, a support ring 36 fixedly connected to one side of the fixed shell 31, and the outer surface of the support ring 36 fixedly connected to one end of the rope 25;

[0024] In the above embodiments, the bracket 21 is used for positioning and fixing, the handle 24 provides the force source, the handle 24 drives the rotating plate 23 to rotate, and the shaft drives the receiving plate 22 to rotate. The clockwise and counterclockwise rotation of the rotating plate 23 can make the rope 25 on the receiving plate 22 retract and extend, which in turn drives the sampling mechanism 3 to move. The two rotating rings 27 can straighten the rope 25 released from the receiving plate 22, making the retraction and extension of the rope 25 more neat, fixing the retraction and extension position, and making the retraction and extension more stable.

[0025] An arc-shaped shell 32 is slidably connected to the inner wall of the fixed shell 31, and a lead block 37 is fixedly connected to one side of the arc-shaped shell 32.

[0026] Through the above embodiments, the lead block 37 can increase the gravity of the sampling mechanism 3, allowing the sampling mechanism 3 to sink into the water, so as to facilitate sampling at different water depths.

[0027] Two semi-rings 33 are fixedly connected to the outer surfaces of the fixed shell 31 and the arc-shaped shell 32. Two threaded grooves 34 are opened between the outer surfaces of the fixed shell 31 and the arc-shaped shell 32. A threaded sleeve 35 is fitted on the outer surface of the threaded grooves 34.

[0028] Through the above embodiments, the fixed shell 31 and the arc-shaped shell 32 can be fixed by the cooperation of the threaded groove 34 and the threaded sleeve 35. The cooperation of the threaded groove 34 and the threaded sleeve 35 facilitates the removal and installation of the fixed shell 31 and the arc-shaped shell 32, increasing the convenience of disassembly and assembly of the fixed shell 31 and the arc-shaped shell 32. The semi-ring 33 is used to limit the threaded sleeve 35.

[0029] The inner wall of the fixed shell 31 is fixedly connected to the first curved plate 313, and the inner wall of the arc-shaped shell 32 is fixedly connected to the second curved plate 314.

[0030] A needle tube 310 is slidably connected to the inner wall of the fixed shell 31. A needle tip 311 is fixedly connected to the bottom of the needle tube 310. The bottom end of the needle tip 311 slides through to the outside of the fixed shell 31. A piston rod 312 is slidably connected to the inner wall of the needle tube 310. Two grooves are formed on the outer surface of the piston rod 312.

[0031] An electric push rod 38 is fixedly connected to the inner top surface of the fixed shell 31. One end of the electric push rod 38 is fixedly connected to a slide 39. The inner wall of the slide 39 is slidably connected to the inner wall of the groove.

[0032] Through the above embodiments, the first curved plate 313 and the second curved plate 314 can limit and fix the needle tube 310, so that the needle tube 310 cannot move after the arc-shaped shell 32 is installed. Then, the piston rod 312 can be moved by the retraction of the electric push rod 38, so as to extract the water source in the area. After the arc-shaped shell 32 is removed, the electric push rod 38 can be retracted to drive the needle tube 310 and the needle 311 into the interior of the fixed shell 31. Then, the needle tube 310, the needle 311 and the piston rod 312 can be removed by sliding, so as to remove the sample inside the needle tube 310.

[0033] Working principle:

[0034] like Figure 1-4 As shown, in use, the syringe 310, needle 311 and piston rod 312 are slid into the interior of the fixed housing 31, and the groove in the piston rod 312 is attached to the slide 39. Then, the syringe 310 is pushed to contact the first curved plate 313 and the piston rod 312 is pushed to contact the interior ground of the syringe 310 by extending the electric push rod 38. Then, the arc-shaped housing 32 is slid into the interior of the fixed housing 31, and the fixed housing 31 and the arc-shaped housing 32 are fixed by two threaded sleeves 35.

[0035] Then, the throttle 24 provides the force source, which drives the rotating plate 23 to rotate, thereby driving the collecting tray 22 to rotate via the shaft. The clockwise and counterclockwise rotation of the rotating plate 23 enables the rope 25 on the collecting tray 22 to be extended and retracted, which in turn drives the sampling mechanism 3 to move. When the sampling mechanism 3 reaches the required position, the electric push rod 38 can be controlled by the external controller to retract and drive the piston rod 312 to move, so that the water in that area can enter the needle tube 310 from the needle tip 311. Then, the collecting tray 22 can be retracted to drive the sampling mechanism 3 to take out the water.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
