Description

Technical Field

[0001] The utility model mainly relates to the field of groundwater sampling equipment, specifically a groundwater sampling device. Background Art

[0002] Hydrogeology is a branch of geology, and studying groundwater is a topic in hydrogeology. Because groundwater is located inside pits, it is sometimes inconvenient for researchers to collect it. Therefore, they need to use relevant sampling equipment.

[0003] A Chinese patent with the opening number CN217211600U discloses a groundwater sampling device for hydrogeological engineering. When in use, the device can facilitate users to sample groundwater at different depths through the setting of a transmission shaft and a pull rope. Then, through the setting of a mounting plate, a movable groove, a movable plate, a clamping rod, a mounting rod, a clamping groove, a spring and a mounting hole, the user can conveniently disassemble and remove the sampling bucket after sampling. The combination of the above structures achieves the purpose of facilitating the disassembly and removal of the sampling bucket after sampling, thereby improving the sampling efficiency.

[0004] The above patent has the following defects: However, in actual use, the pull rope will be wrapped around various places on the surface of the drive shaft. Therefore, during the winding process, when the position of the pull rope wrapped around the surface of the drive shaft changes, the pull rope will be tilted, which will cause the sampling bucket to collide with the wall of the sampling port pit, causing some impurities on the pit wall to fall into the water sample, affecting the accuracy of sampling.

[0016] The present invention will be further described with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the contents of this invention, those skilled in the art may make various changes or modifications to the present invention, and that such equivalent forms also fall within the scope defined in this application.

[0017] like Figure 1-2As shown, the utility model describes a groundwater sampling device, comprising a U-shaped plate 1, connecting plates 2 are installed on both sides of the bottom surface of the U-shaped plate 1, and two rollers 3 distributed front and back are installed on the bottom surface of each connecting plate 2, and the rollers 3 have a braking function. Two telescopic rods 4 distributed left and right are installed on the top surface of the U-shaped plate 1, and a placement plate 5 is installed between the bottom ends of the two telescopic rods 4. A connecting sleeve 6 is installed on the top surface of the placement plate 5, and a vertical rod 7 is provided in the connecting sleeve 6. The vertical rod 7 is separable from the connecting sleeve 6, and a fastening knob 8 is installed on the connecting sleeve 6. The fastening knob 8 can contact and cooperate with the vertical rod 7, and the bottom end of the vertical rod 7 can be disassembled to install a sampling bucket 9.

[0018] Specifically, a PLC control box 10 is installed on the top surface of the U-shaped plate 1, and the PLC control box 10 is connected to the telescopic rod 4. The PLC control box 10 can control the movement of the telescopic rod 4.

[0020] Specifically, a handle 12 is installed on the front of the U-shaped plate 1.

[0021] Example:

[0022] When using this device, first move the device to the sampling position by rolling the roller 3, then connect the vertical rod 7 with the connecting sleeve 6, and fix the vertical rod 3 in the connecting sleeve 6 by tightening the knob 8, and then control the telescopic rod 4 to extend downward through the PLC control box 10. The extension of the telescopic rod 4 drives the placement plate 5 to move downward, and the movement of the placement plate 5 drives the connecting sleeve 6 and the vertical rod 7 to move downward. The movement of the vertical rod 7 drives the sampling bucket 9 to move downward, and the sampling bucket 9 is extended into the sampling pit, and then sampling is carried out. Driven by the extension of the telescopic rod 4, the sampling bucket 9 will not shake in the axial direction, thereby avoiding the collision between the sampling bucket 9 and the inner wall of the sampling pit, thereby avoiding debris falling into the sampling bucket 9.

The extension and contraction of the telescopic rod can drive the connecting sleeve to move up and down, and then drive the sampling bucket to move up and down, so that the sampling bucket is conveniently inserted into the underground sampling port for sampling, avoiding the shaking of the sampling bucket and the collision with the sampling port. At the same time, the vertical rod and the connecting sleeve can be separated, which is convenient for installing the sampling bucket and facilitating the insertion of the sampling bucket into the sampling port, thereby bringing convenience to groundwater sampling.
