Hydrogeological stratified sampling device

Abstract

The invention belongs to the technical field of hydrogeological exploration, and particularly relates to a hydrogeological stratified sampling device which comprises a base, a frame is fixedly connected to one side of the upper end face of the base, a winding disc is rotatably arranged on one side of the upper end of the frame, a rope is wound on the winding disc, and a sampling bottle is fixedly connected to the lower end of the rope. And the frame body is also provided with a winding type pushing mechanism for preventing a plant root system on the water surface from influencing the sampling work. By utilizing the winding type pushing mechanism, when a plant root system exists on the water surface of the descending area of the sampling bottle, one side of the rotating roller can be in contact with the plant root system by adjusting the direction of the rotating roller, then the rotating roller is driven to transversely move again, the plant root system is pushed to be away from the descending area of the sampling bottle, and at the moment, the plant root system is pushed to be away from the descending area of the sampling bottle. And then the sampling bottle is driven to enter water, so that the condition that the plant root system is wound on the surface of the sampling bottle and covers the water inlet can be avoided, and the sampling work is ensured to be smoothly carried out.

Description

Technical Field

[0001] The invention belongs to the technical field of hydrogeological exploration, in particular to a hydrogeological stratified sampling device. Background Art

[0002] Hydrogeology is a branch of geology that mainly studies the distribution and formation of groundwater. By sampling groundwater, groundwater samples can be obtained. After analysis, the hydrogeological conditions of the drilling area can be determined, providing important basis and guidance for the implementation of engineering projects.

[0003] The patent with announcement number CN212079292U discloses an automatic water level collector for hydrogeological boreholes, including a bracket, on which the upper end surface of the bracket is sequentially mounted from left to right with a collector body, a winding mechanism, and a controller. Through the setting of the sampling mechanism, while the water level probe detects the water level, the water source in the hole enters the sampling mechanism through the four water inlet holes on the sealing cover, so that the water level probe on the water level collector can effectively sample the water source in the hole while detecting the water level, thereby improving the practicality of the water level collector. Through the setting of the anti-backflow flap door, even if the water level probe and the sampling mechanism shake when moving upward in the hole, the water source collected in the sampling mechanism will not be shaken out, thereby effectively improving the reliability of the sampling mechanism during sampling.

[0004] However, the above technical solution still has the following deficiencies in practical application: The sampling mechanism is connected to a conducting wire and the conducting wire is unwound so that the sampling mechanism enters the groundwater through a borehole to sample the groundwater. However, in order to sample the groundwater, a hole must be drilled on the surface first. During the drilling process, the rotation and cutting action of the drill bit may bring plant roots into the borehole, causing the plant roots to float on the surface of the groundwater. When the sampling mechanism enters the water, these plant roots may become entangled with the sampling mechanism, which may easily cause the water inlet of the sampling mechanism to be covered, thereby affecting the normal progress of subsequent sampling work.

[0005] To this end, the present invention provides a hydrogeological stratified sampling device. Summary of the invention

[0017] The beneficial effects of the present invention are as follows: 1. The hydrogeological stratified sampling device described in the present invention utilizes a second motor to drive the winding disk to rotate, and the rope can be unwound to drive the sampling bottle down, so that the sampling bottle enters the groundwater. When the sampling bottle reaches the depth required for sampling, the solenoid valve on either side is opened to allow the groundwater to flow into the storage cell between the partitions. Moreover, since there are multiple water inlets and partitions, different water layers can be sampled, thereby improving the comprehensiveness of the sampling and facilitating the subsequent analysis of the groundwater samples.

[0018] 2. The hydrogeological stratified sampling device described in the present invention utilizes a winding and pushing mechanism. When there are plant roots on the water surface in the area where the sampling bottle descends, the orientation of the rotating roller can be adjusted so that one side of the rotating roller contacts the plant roots, and then the rotating roller is driven to move laterally again to push the plant roots away from the descending area of ​​the sampling bottle. At this time, the sampling bottle is driven into the water again to avoid the plant roots being entangled on the surface of the sampling bottle and covering the water inlet, thereby ensuring the smooth progress of the sampling work. Moreover, when the rotating roller pushes the plant roots away, the two clamping blocks can be driven close to each other to clamp the plant roots, thereby avoiding the plant roots returning to the top of the sampling bottle due to the fluctuation of the water surface. When the sampling bottle is removed from the water, it is again entangled by the plant roots. The subsequent sampling work proceeds normally, and whenever the clamping block clamps the plant roots, the rotating roller is driven to rotate, and the plant roots can be wrapped around the surface of the rotating roller with the cooperation of the pressure roller. When the plant roots are rolled up, the two clamping blocks are driven to loosen the plant roots, and the clamping blocks are retracted into the inner cavity of the rotating roller. Then the conical ring is driven to move, and its inner edge cuts into between the rotating roller and the pressure roller, and the inner edge of the conical ring will form a scraping with the surface of the rotating roller to push the plant roots wrapped around the surface of the rotating roller to the end of the rotating roller and drop through the end of the rotating roller. Since the plant roots are changed from long strips to rolled states, at this time, even if the plant roots move with the water flow, they will not be wrapped around the surface of the sampling bottle. Moreover, since the plant roots on the surface of the rotating roller are removed, the continuous operation of the rotating roller is not affected. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Specifically, when the existing water sampler is used, the sampling mechanism is connected to the wire, and the wire is unwound so that the sampling mechanism enters the groundwater through the borehole to sample the groundwater. However, in order to sample the groundwater, it is necessary to drill a hole on the surface of the ground first. During the drilling process, due to the rotation and cutting action of the drill bit, plant roots may be brought into the borehole, so that the plant roots float on the surface of the groundwater. When the sampling mechanism enters the water, these plant roots may be entangled on the sampling mechanism, which may easily cause the water inlet of the sampling mechanism to be covered, thereby affecting the normal progress of subsequent sampling work. Therefore, in order to solve the above problems, when the present embodiment is used, after determining the descending area of ​​the sampling bottle 12, the motor 3 10 is first used to drive the gear 36 to rotate, so that the rack 11 slides downward, so that the rotating roller 28 is on the water surface, and the water surface situation can be observed by the camera 14. When there are plant roots on the water surface of the descending area of ​​the sampling bottle 12, the motor 4 17 can be used to drive the connecting rod 1 16 and the connecting rod 2 18 to rotate, so that the adjustment plate 19 and the rotating roller 28 move laterally, so that the rotating roller 28 is above the plant root system, and then the rotating roller 28 is driven down again, so that it is on the side of the plant root system, and one side of the rotating roller 28 contacts the plant root system, and then the rotating roller 28 is driven to move laterally again, so that the plant root system can be pushed away from the descending area of ​​the sampling bottle 12. At this time, the sampling bottle 12 is driven into the water again, so that the plant roots are prevented from being entangled on the surface of the sampling bottle 12 and covering the water inlet 37, thereby ensuring the smooth progress of the sampling work; Furthermore, although the rotating roller 28 can be used to push the plant roots away from the submerged area of ​​the sampling bottle 12, when the sampling bottle 12 enters the water, the wave of the water surface may cause the pushed-away plant roots to return to the top of the sampling bottle 12. Although the plant roots will no longer cover the water inlet 37, when the sampling bottle 12 is removed from the water, it will contact the plant roots again, causing the sampling bottle 12 to be entangled. When the next sampling location is changed, the sampling bottle 12 is entangled by the plant roots. Therefore, in order to avoid this problem, when the rotating roller 28 pushes the plant roots away, since the plant roots are between the two clamping blocks 44, the motor 43 can be used to drive the bidirectional threaded rod 33 to rotate so that the two clamping blocks 44 are close to each other to clamp the plant roots, thereby avoiding the situation that the plant roots return to the top of the sampling bottle 12 due to the fluctuation of the water surface, and when the sampling bottle 12 is removed from the water, it is entangled by the plant roots again, and the subsequent sampling work can proceed normally; Although the plant roots can be fixed by the above operation to prevent them from moving with the water flow, when the number of plant roots is large, it is difficult for the clamping block 44 to fix all the plant roots at once, and some plant roots will still flow, resulting in the above-mentioned situation that the plant roots are entangled with the sampling bottle 12. Therefore, in order to avoid this situation, every time the clamping block 44 clamps the plant roots, the motor 6 is used to drive the rotating roller 28 to rotate. When the clamping block 44 contacts the pressure roller 27, the pressure roller 27 will be regularly moved, the sliding column 24 will slide, the spring 25 will be compressed, and after the clamping block 44 passes through the pressure roller 27, the pressure roller 27 will reset and press the plant roots again, that is, under the continuous rotation of the rotating roller 28, the plant roots will be entangled with the surface of the rotating roller 28. When the plant roots are rolled up, the two clamping blocks 44 are driven to clamp the plant roots. Loosen, and then use motor six 29 to drive the threaded rod 30 to rotate, so that the clamping block 44 is retracted into the inner cavity of the rotating roller 28, and then use motor five 20 to drive connecting rod three 21 and connecting rod four 22 to rotate, so that the conical ring 41 can move. When the conical ring 41 moves, it can cut into between the rotating roller 28 and the pressure roller 27 through its inner edge, and the inner edge of the conical ring 41 will form a scraping with the surface of the rotating roller 28 to push the plant roots wrapped around the surface of the rotating roller 28 to the end of the rotating roller 28 and drop through the end of the rotating roller 28. Since the plant roots are changed from long strips to a rolled state, at this time, even if the plant roots move with the water flow, they will not be wrapped around the surface of the sampling bottle 12. In addition, since the plant roots on the surface of the rotating roller 28 are removed, the continuous operation of the rotating roller 28 is not affected.

[0035] Working principle: by holding the handle 3, the base 1 can be moved to the specified position by the universal wheel 13, and the sampling bottle 12 is aligned with the drill hole, and the motor 3 10 is first used to drive the gear 36 to rotate, so that the rack 11 slides downward, so that the rotating roller 28 is on the water surface, and the water surface situation can be observed by the camera 14. When there are plant roots on the water surface in the area where the sampling bottle 12 falls, the motor 4 17 can be used to drive the connecting rod 1 16 and the connecting rod 2 18 to rotate, so that the adjustment plate 19 and the rotating roller 28 move horizontally, so that the rotating roller 28 is above the plant roots, and then the rotating roller 28 is driven down again to be above the plant roots. The rotating roller 28 is moved laterally to one side of the plant root system, and one side of the rotating roller 28 is in contact with the plant root system, and then the rotating roller 28 is driven to move horizontally again, so that the plant root system can be pushed away from the descending area of ​​the sampling bottle 12. At this time, the winding disk 7 is driven to rotate by the motor 28, and the rope 9 can drive the sampling bottle 12 to descend by unwinding, so that the sampling bottle 12 enters the groundwater. When the sampling bottle 12 reaches the depth required for sampling, the electromagnetic valve 40 on either side is opened, so that the groundwater can flow into the storage cell between the partitions 38. In addition, since the water inlet 37 and the partition 38 are provided in multiple numbers, different water layers can be sampled. The sampling bottle 12 is provided with a plurality of rollers 28, and the roots of the plants are pushed away from the submerged area of ​​the sampling bottle 12. However, when the sampling bottle 12 enters the water, the roots of the plants that are pushed away may return to the top of the sampling bottle 12 due to the fluctuation of the water surface. Although the roots of the plants will no longer cover the water inlet 37, when the sampling bottle 12 is removed from the water, the roots of the plants will contact with the roots of the plants again, causing the sampling bottle 12 to be stuck. 2 is entangled, and when changing the next sampling location, since the sampling bottle 12 has been entangled by the plant roots, the subsequent sampling work is affected. Therefore, in order to avoid this problem, when the rotating roller 28 pushes the plant roots away, since the plant roots are between the two clamping blocks 44, the motor 7 43 can be used to drive the bidirectional threaded rod 33 to rotate, so that the two clamping blocks 44 are close to each other to clamp the plant roots, which can avoid the plant roots returning to the top of the sampling bottle 12 due to the fluctuation of the water surface. When the sampling bottle 12 is removed from the water, it is entangled by the plant roots again, and the subsequent sampling work is carried out normally;Although the plant roots can be fixed by the above operation to prevent them from moving with the water flow, when the number of plant roots is large, it is difficult for the clamping block 44 to fix all the plant roots at once, and some plant roots will still flow, resulting in the above-mentioned situation that the plant roots are entangled with the sampling bottle 12. Therefore, in order to avoid this situation, every time the clamping block 44 clamps the plant roots, the motor 6 is used to drive the rotating roller 28 to rotate. When the clamping block 44 contacts the pressure roller 27, the pressure roller 27 will be regularly moved, the sliding column 24 will slide, the spring 25 will be compressed, and after the clamping block 44 passes through the pressure roller 27, the pressure roller 27 will reset and press the plant roots again, that is, under the continuous rotation of the rotating roller 28, the plant roots will be entangled with the surface of the rotating roller 28. When the plant roots are rolled up, the two clamping blocks 44 are driven to clamp the plant roots. Loosen, then use motor 6 29 to drive threaded rod 30 to rotate, so that clamp 44 is retracted into the inner cavity of rotating roller 28, and then use motor 5 20 to drive connecting rod 3 21 and connecting rod 4 22 to rotate, so that conical ring 41 can move. When conical ring 41 moves, its inner edge can cut into between rotating roller 28 and pressing roller 27, and the inner edge of conical ring 41 will form a scraping with the surface of rotating roller 28 to push the plant roots wrapped around the surface of rotating roller 28 to the end of rotating roller 28 and drop through the end of rotating roller 28. Since the plant roots are changed from long strips to rolled state, at this time, even if the plant roots move with the water flow, they will not be wrapped around the surface of sampling bottle 12. Moreover, since the plant roots on the surface of rotating roller 28 are removed, the continuous operation of rotating roller 28 is not affected. ;
