Description

Technical Field

[0001] The utility model relates to the technical field of groundwater sampling, especially a municipal groundwater sampling device. Background Art

[0002] Municipal underground water intake refers to the process of obtaining water resources from underground water sources to meet the water requirements for urban public services and infrastructure operation. The inertial pump is a commonly used groundwater sampling device that generates negative pressure to suck water by quickly moving the drive pipe column up and down, and is suitable for small-diameter monitoring wells or low-flow sampling.

[0003] Chinese Patent No. CN202311780405.7, an inertial pump for automatic pumping water. In this inertial pump, by setting a turntable, specifically when the turntable rotates, the fixed shaft rotates within the arc track, which will drive the arc track to move downward or upward. Then the arc track drives the push rod through the connecting seat, and reciprocating in this way can make the inertial pump body pump water. Driving the inertial pump body to pump water by rotating can improve the pumping efficiency, and the device has a compact structure and stronger stability, avoiding shaking and improving safety. This inertial pump needs to quickly lift the drive rod to pump out the groundwater. In mountainous areas and other places with complex road conditions, vehicles are difficult to reach, and the motor cannot be brought to the water intake point. It is necessary to manually operate the inertial pump to draw water, but it is very difficult for people to continuously and quickly lift the drive rod, resulting in failed water intake. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a municipal groundwater sampling device to solve the problems raised in the related technology.

[0027] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following, in conjunction with the drawings and preferred embodiments, details the specific implementation manners, structures, features and their effects of the present utility model as follows.

[0028] This embodiment provides a municipal groundwater sampling device, as Figure 1 shown, which includes a water pipe part 1 and a driving rod part 2 arranged above the interior of the water pipe part 1, and further includes: a driving part 4, the driving part 4 is arranged inside the water pipe part 1 and is connected to the bottom end of the driving rod part 2;

[0029] a check part 3, the check part 3 is arranged above the driving part 4. When the driving part 4 moves upward, the check part 3 blocks the driving part 4, and negative pressure suction appears below the water pipe part 1; when the driving part 4 moves downward, the check part 3 leaves the driving part 4, and the groundwater below the interior of the water pipe part 1 passes through the driving part 4 and enters the upper part of the interior of the water pipe part 1.

[0030] As Figure 2 shown, the water pipe part 1 includes a water pipe body group, a top cover 13 and a check valve 15, and the water pipe body group includes a water pipe body 11, a pipe cavity 12 and an outlet pipe 14.

[0031] The lumen 12 is provided inside the water pipe body 11. The one-way valve 15 is provided at the bottom of the lumen 12 and is fixedly connected to the water pipe body 11. The top cover 13 is fixedly provided at the top of the water pipe body 11. The water outlet pipe 14 is fixedly provided on the side of the water pipe body 11 in a downward inclined manner and is communicated with the lumen 12.

[0032] As Figure 3 shown, the driving rod part 2 includes a driving rod body 21 and a handle 22. The driving rod body 21 penetrates through the top cover 13 and is inserted into the lumen 12. The driving rod body 21 is slidably connected to the top cover 13. The handle 22 is fixedly provided at the top end of the driving rod body 21 and is located above the top cover 13.

[0033] As Figure 4 shown, the driving part 4 includes a driving disk group and a hole groove group. The driving disk group includes a driving disk 41, a plurality of guide rods 45, an annular groove 46, a plurality of connecting pieces 47 and two convex rings 49. The hole groove group includes an inner groove 42, an outer groove 43, a plurality of column holes 44 and a plurality of through holes 48.

[0034] The driving disk 41 is fixedly provided at the bottom end of the driving rod body 21 and is slidably connected to the inner wall of the water pipe body 11. A sealing ring is fixedly provided on the outer circle of the driving disk 41, so that the driving disk 41 is in close contact with the inner wall of the water pipe body 11, which is beneficial to forming negative pressure suction below the water pipe body 11.

[0035] The annular groove 46 is penetrated through the driving disk 41. The inner groove 42 and the outer groove 43 are respectively located on the inner and outer sides of the annular groove 46 and are located on the upper surface of the driving disk 41. The two convex rings 49 are respectively located on the outer side of the inner groove 42 and the inner side of the outer groove 43 and are located on the inner and outer sides of the annular groove 46.

[0036] A plurality of connecting pieces 47 are provided at the bottom end inside the annular groove 46. Both ends of the connecting pieces 47 are fixedly connected to the bottom ends of the two convex rings 49. Through holes 48 are provided through the connecting pieces 47. A plurality of through column holes 44 are provided on the inner groove 42 and the outer groove 43. A plurality of guide rods 45 are fixedly provided on the top of the two convex rings 49. A retaining piece is fixedly provided at the top of the guide rod 45 to prevent the guide rod 45 from sliding out of the guide hole 35, resulting in the check part 3 being separated from the driving part 4. The column holes 44 are used to accommodate the convex columns 34, so that the check part 3 tightly covers the driving part 4, and the accumulated water in the inner groove 42 and the outer groove 43 can flow down from the column holes 44, reducing the weight of the driving part 4 and facilitating lifting.

[0037] As Figure 5 shown, the check part 3 includes a check piece group and a hole channel group. The check piece group includes a check piece 31 and a middle hole 32. The hole channel group includes two grooves 33, a plurality of convex columns 34 and a plurality of guide holes 35.

[0038] The middle hole 32 runs through the middle of the check valve piece 31 for accommodating the driving rod body 21. The grooves 33 are all arranged below the check valve piece 31 for accommodating the convex ring 49. The convex columns 34 are all fixedly arranged below the check valve piece 31 and correspond to the column holes 44. The guide rod 45 passes through the guide hole 35, and the check valve piece 31 slides up and down along the guide rod 45.

[0039] The length of the water pipe body 11 of the present utility model is 30 meters. Therefore, the present utility model is applicable to shallow groundwater with a well depth less than 30 meters.

[0040] Insert one end of the water pipe body 11 with the one-way valve 15 downward into the water intake well. Stop inserting when the one-way valve 15 is below the water surface. Fix the upper end of the water pipe body 11 on the ground with an external bracket so that the water outlet pipe 14 is on the ground. Place a water container under the water outlet pipe 14 to prepare for receiving the groundwater discharged from the water outlet pipe 14.

[0041] Pull up the handle 22 upward. The handle 22 drives the check part 3 and the driving part 4 to move upward through the driving rod body 21 until the check part 3 and the driving part 4 are about to contact the top cover 13 and stop pulling. A negative pressure appears below the water pipe body 11, and the one-way valve 15 is opened due to the pressure imbalance on both sides. The groundwater surges into the water pipe body 11 through the one-way valve 15. Then, press the handle 22 downward. The handle 22 drives the check part 3 and the driving part 4 to move downward through the driving rod body 21. The negative pressure below the water pipe body 11 disappears, and the one-way valve 15 closes, intercepting the groundwater in the water pipe body 11. The pressure below the driving part 4 moving downward is greater than the pressure above it. The pressure difference pushes the check part 3 to slide upward along the guide rod 45, leaving the annular groove 46. The annular groove 46 opens, making the pressure on both sides of the driving part 4 balanced and facilitating the downward movement of the driving part 4. When the handle 22 is about to touch the top cover 13, stop pressing the top cover 13 and switch to pulling upward. Under the action of its own weight, the check part 3 moves downward to block the annular groove 46, and a negative pressure for sucking water appears below the water pipe body 11 again. Repeat this process until all the air in the water pipe body 11 is exhausted. After pressing the handle 22 downward again, the groundwater in the water pipe body 11 pushes up the check part 3 and enters the area above the check part 3 from the annular groove 46. As the driving part 4 moves upward, the groundwater is discharged from the water outlet pipe 14 and collected.

[0042] The check part 3 can slide up and down above the driving part 4. When the driving part 4 moves upward, the check part 3 moves downward and presses on the driving part 4 to block the annular groove 46, causing a negative pressure for sucking water to appear below the water pipe body 11. When the driving part 4 moves downward, the air or groundwater below the water pipe body 11 enters above the water pipe body 11 from the annular groove 46. After all the air in the water pipe body 11 is exhausted, the groundwater begins to enter above the water pipe body 11 and is collected. Since the check part 3 blocks the annular groove 46 when the driving part 4 moves upward and air cannot enter the water pipe body 11, the groundwater can be pumped out without quickly pulling up the driving part 4.

[0043] The above are only the preferred embodiments of the present utility model, and do not impose any form of limitation on the present utility model. Although the present utility model has been disclosed above with the preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the disclosed technical content within the scope of the technical solution of the present utility model. However, as long as it does not depart from the content of the technical solution of the present utility model, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
