Description

Technical Field

[0001] This invention relates to the field of environmental monitoring technology, specifically to an environmental geological sampling device. Background Technology

[0002] Groundwater refers to water found in the pores of rocks below the ground surface, or more specifically, water in saturated aquifers below the water table. Groundwater is a crucial component of water resources, and due to its stable quantity and good quality, it is an important source of water for agricultural irrigation, mining, and urban use. Currently, humans primarily utilize shallow groundwater, mainly through well drilling. Human activities also contribute to groundwater pollution, especially with the increasing threat posed by chemical waste from heavy industry. Therefore, groundwater quality monitoring has become an essential aspect of human life.

[0003] Current groundwater testing typically involves drilling monitoring wells and then using instruments to sample groundwater at depths of 40-100 meters. However, with increasing human activity, environmental pollutants pose a growing threat to groundwater. While deeper groundwater is normally unaffected by pollution, the worsening pollution, through soil infiltration, means that even with soil's inherent degradation capabilities, it cannot completely eliminate the pollution at deeper levels. Therefore, the degree of pollution may vary at different depths, and current technology lacks equipment that can easily sample groundwater at deeper depths. Summary of the Invention

Simultaneously, it allows for sliding and lifting within its interior. Furthermore, the drill rod pushing device 60 is connected to the multi-stage drill rod 50 via abutment and rotation. The drill rod pushing device 60 and the drill rod rotating device 70 drive the multi-stage drill rod 50 to rotate and descend simultaneously, allowing the multi-stage drill rod 50 to rotate and drill into the ground. Furthermore, the multi-stage drill rod 50 is configured with a multi-stage extension structure, allowing it to be extended to different lengths for drilling at different depths. Simultaneously, the groundwater sampling device 30 is connected to the multi-stage drill rod 50 via a conduit, thereby completing groundwater sampling at different depths below ground level.

[0017] For details, please refer to the following: Figure 1-3The frame support structure 10 includes a triangular support frame 101, a gear disk support bearing disk 105, a pulley disk support bearing disk 108, and a frame support rod 1014.

[0021] In this embodiment, the rotating gear disk 301 is mounted on the upper part of the gear disk support bearing disk 105 and rotatably connected to it, allowing the rotating gear disk 301 to rotate via the bearing structure. Furthermore, the gear motor 305 drives the gear 306 to mesh with the gear teeth 302, causing the rotating gear disk 301 to rotate, thereby enabling the groundwater sampling device 30 to rotate synchronously with the multi-stage drill bit rod 50. A conduit rotation shaft 307 is further provided so that the conduit 308 rotates with the multi-stage drill bit rod 50. During the process of penetrating deep into the ground, the rotating shaft 307 of the conduit can rotate to extend the conduit 308.

[0022] For details, please refer to the following: Figure 1-3 7. The drill rod pushing device 60 includes an electric cylinder support plate 601, a drill rod pushing tube 604, and a pushing block 6010. The electric cylinder support plate 601 is fixedly installed on the bottom of one side of the support rod 106.

A connecting lifting plate 603 is fixedly installed at the output end of the electric cylinder 602. The drill rod pushing tube 604 is fixedly installed at the end of the connecting lifting plate 603. A rotating bearing 605 is fixedly installed inside the drill rod pushing tube 604. A drill bit is fixedly sleeved on the outer ring of the rotating bearing 605. The drill rod rotating ring 606 has a rotation limiting block 607 fixedly provided on one side of its lower part. The drill rod push tube 604 has push block grooves 608 on both sides of its lower part. The push block grooves 608 have threaded holes 609 on their outer sides. The push block 6010 is installed inside the push block grooves 608 and is slidably connected to them. The push block 6010 has a rotating threaded rod 6011 on its outer side, which is rotatably connected to it and installed inside the threaded holes 609 and threadedly engaged with it. The end of the rotating threaded rod 6011 is fixedly provided with a rotating knob 6012.

[0023] In this embodiment, the electric cylinder 602 extends and retracts, driving the drill rod push tube 604 to rise and fall.

Further, a rotation limiting block 607 is installed inside the limiting block groove 507 on the upper part of the multi-stage connecting column 505 or semi-circular multi-stage connecting column 5015, thereby limiting the connection between the drill rod rotating ring 606 and the multi-stage connecting column 505 or semi-circular multi-stage connecting column 5015, thus ensuring the drill rod rotating ring... 606 can rotate synchronously with both, and further drive the drill rod push tube 604 to descend via the electric cylinder 602, pushing the multi-stage drill bit rod 50 to descend and drill into the ground. Further, push blocks 6010, which can be pushed by the rotating threaded rod 6011, are provided on both sides of the lower part of the drill rod push tube 604. These blocks push the push blocks 6010 to the multi-stage connecting limiting groove 506 opened on the bottom side of the multi-stage connecting column 505 or the semi-circular multi-stage connecting column 5015, so that they are limited and connected with the drill rod push tube 604. This allows the electric cylinder 602 to rise and drive the multi-stage drill bit rod 50 to rise, thereby allowing the multi-stage drill bit rod 50 to be removed from the ground.

[0024] For details, please refer to the following: Figure 1-3 8. The drill rod rotating device 70 includes a pulley rotating ring 701 and a pulley motor support plate 705.

A drive pulley 707 is fixedly provided coaxially at the output end of the pulley motor 706. A transmission belt 708 is sleeved on the outer periphery of the drive pulley 707 and the rotating pulley 704.

[0025] In this embodiment, the drive pulley 707 is rotated by the pulley motor 706, which in turn drives the transmission belt 708 and the rotating pulley 704 to rotate synchronously. This causes the pulley connecting ring 702 and the pulley rotating ring 701 to rotate inside the pulley disc support bearing disc 108. Furthermore, the drill rod limiting groove 703 cooperates with the drill rod limiting strip 504 provided on the outer periphery of the multi-stage drill rod 50 to drive the multi-stage drill rod 50 to rotate synchronously and allow the multi-stage drill rod 50 to slide inside the pulley connecting ring 702. This allows it to be pushed down by the drill rod pushing device 60.
