Description

Technical Field

[0001] This utility model relates to the field of environmental protection technology, and in particular to a treatment device for shallow groundwater pollution. Background Technology

[0002] Shallow groundwater pollution treatment devices are environmental protection equipment specifically designed to remediate polluted shallow groundwater. Typically, these devices need to be buried in the soil of the polluted shallow groundwater area during use. Pollution remediation solutions are injected into the storage tank through a dosing pipe, and the solutions flow out through the dispersing holes, penetrating into the soil, i.e., the groundwater layer, to remediate the pollutants.

[0003] Chinese Patent 202422474566.X discloses a device for treating shallow groundwater pollution, including a storage tank with a dosing port at the top. Four spring steel plates are evenly and fixedly connected in a circular pattern on the bottom side wall of the storage tank. The spring steel plates and the dispensing hose are subjected to force and slowly penetrate into the shallow water layer. After the dispensing hose has completely entered the shallow water layer, the rotation of the T-shaped pressure rod stops. A water pollution treatment agent is added into the storage tank through the dosing port. The delivery pump is started, and the agent enters the inlet of the delivery pump. The delivery pump delivers the agent to the delivery pipe, and then through the connecting hose to deliver it to two dispensing hoses. Subsequently, the agent seeps into the shallow water layer through the dispensing holes on the dispensing hoses to treat the water pollution. While the device is treating the water, the water pump sucks the surrounding untreated water into a sampling bottle through a retractable hose, which can detect the water quality of other areas in advance to determine whether the water pollution in this area is serious and which agent needs to be used for treatment.

[0004] However, the above-mentioned treatment device requires adjustment of four T-shaped pressure rods to drive the pressure ring to rise and fall, which is quite troublesome. Therefore, a treatment device for shallow groundwater pollution is proposed to solve the above problems. Utility Model Content

[0027] like Figure 1-3 As shown, the present invention proposes a treatment device for shallow groundwater pollution, including a cover plate 2 and a pressure ring 16. A medicine storage tank 3 is provided in the middle of the lower end of the cover plate 2, and the pressure ring 16 is located on the outer end face of the medicine storage tank 3. A double-headed motor 10 is provided in the middle of the upper end of the cover plate 2, and a feed pipe 15 connected to it is also provided on the side of the upper end of the cover plate 2.

[0028] The device includes threaded rods 9, which are symmetrically distributed and vertically penetrate the upper end of the cover plate 2 and are connected to the top of the pressure ring 16. Both drive ends of the dual-head motor 10 are coaxially connected to transmission rods 17. The ends of the transmission rods 17 away from the dual-head motor 10 are respectively connected to the threaded rods 9 on both sides through connecting components. A protective shell 1 is provided outside the connecting components and at the upper end of the cover plate 2. The protective shell 1 can protect the connecting components.

[0029] Both ends of the bottom of the pressure ring 16 are vertically provided with insertion tubes 6, and multiple drug dispersing holes 5 are provided on the insertion tubes 6 at intervals.

[0030] The medicine storage tank 3 is equipped with a water pumping assembly inside. The water outlets on both sides of the water pumping assembly are connected to the two side insertion pipes 6 via connecting hoses 4. A limiting ring 12 is provided at the outer ring of the bottom of the cover plate 2.

[0031] In this invention, during use, a well is drilled that can directly reach the shallow water layer. Then, the medicine storage tank 3 is inserted into the well, and the cover plate 2 abuts against the well opening. The cover plate 2 is limited by the limiting ring 12. Then, the dual-head motor 10 is started. The dual-head motor 10 can drive the transmission rods 17 on both output ends to rotate. Then, through the connecting components on both sides, it drives the threaded rods 9 on both sides to rotate, thereby driving the pressure ring 16 to descend. When the insertion tube 6 is inserted into the shallow water layer, the medicine can be added into the medicine storage tank 3 through the feed pipe 15. Then, the water pump 14 is started. At this time, the water pump 14 can extract the medicine from the medicine storage tank 3 and deliver the medicine liquid through the T-shaped pipe 13 and the connecting hose 4 to the insertion tubes 6 on both sides. Then, the medicine liquid is discharged into the shallow water layer through the multiple medicine dispersing holes 5 on the insertion tube 6 for water pollution treatment.

[0032] In an optional embodiment, the connecting assembly includes a second bevel gear 19 and a first bevel gear 18. The second bevel gear 19 is rotatably connected to the upper end of the cover plate 2. The threaded rod 9 is threaded vertically through the middle of the second bevel gear 19. The end of the transmission rod 17 away from the dual-head motor 10 passes through the protective housing 1 and is coaxially connected to the first bevel gear 18. The first bevel gear 18 and the second bevel gear 19 mesh with each other.

[0033] It should be noted that when the dual-head motor 10 is started, the dual-head motor 10 can drive the transmission rods 17 on both output ends to rotate. When the transmission rods 17 on both sides rotate, they can drive the first bevel gears 18 on both sides to rotate. When the first bevel gears 18 rotate, they can drive the second bevel gears 19 that mesh with them to rotate on the cover plate 2, thereby driving the threaded rod 9 connected to it to rotate in a threaded manner, so that it can drive the pressure ring 16 to rise and fall.

[0034] The inner diameter of the pressure ring 16 is larger than the outer diameter of the medicine storage tank 3 to prevent the pressure ring 16 from contacting the connecting hose 4 when it is raised or lowered, and to prevent the pressure ring 16 from damaging the connecting hose 4 when it is raised or lowered.

[0035] In an optional embodiment, the threaded rod 9 extends vertically through the upper end face of the protective housing 1, and the top of the threaded rod 9 is connected to the limiting block 8.

[0036] It should be noted that the limiting block 8 can limit the threaded rod 9 and prevent it from coming off.

[0037] In an optional embodiment, a mounting base 11 is rotatably connected to the outer end face of the transmission rod 17, and the bottom of the mounting base 11 is connected to the top of the cover plate 2.

[0038] It should be noted that the mounting base 11 ensures the stability of the transmission rod 17 during rotation.

The pump 14 is located on the inner bottom wall of the medicine storage tank 3, and the T-shaped pipe 13 is located on the upper water outlet end of the pump 14. The two water outlet ends of the T-shaped pipe 13 pass through the outer wall of the medicine storage tank 3 and are respectively connected to the connecting hose 4.

[0040] It should be noted that when the water pump 14 is started, the water pump 14 can draw out the medicine liquid inside the medicine storage tank 3 and transport the medicine liquid to the water pumps 14 on both sides through the T-shaped pipe 13.

[0041] In an optional embodiment, the bottom of the cannula 6 is provided with a conical block 7.

[0042] It should be noted that the conical block 7 facilitates the insertion of the insertion tube 6 into the shallow water layer when it moves downwards.
