Description

Technical Field

[0001] The utility model relates to the technical field of soil sampling, in particular to a drilling sampling device for geological environment monitoring. Background Technique

[0002] Geological environment monitoring refers to the process of systematically and continuously observing, measuring, recording, and analyzing the state and dynamic changes of geological elements such as the surface layer of the lithosphere and the groundwater and soil it contains by using a variety of technical means. Its core goal is to master the current situation of the geological environment, predict its change trend, evaluate the possible risks (especially geological disaster risks), and provide scientific basis and decision-making support for the rational utilization of resources, environmental protection, spatial planning, and engineering construction safety.

[0003] During the process of geological environment monitoring, it is necessary to drill and sample the soil in order to conduct experimental analysis (physical and mechanical properties, chemical composition, etc.) on the obtained soil samples later.

[0004] A geological environment monitoring sampling device disclosed in Chinese Patent CN214952294U is easy to carry and has good stability. However, compared with the prior art and the comparison scheme, the following problems still exist in the actual use of this sampling device:

[0005] When the viscosity of the sampled soil is relatively large, during the process of inserting the sampling cylinder into the soil, the inner wall of the sampling cylinder adheres to the soil, and there is relative movement between the soil and the rotating sampling cylinder. The relative movement between the sampling cylinder and the soil entering the sampling cylinder rubs against each other, which will cause disturbance to the soil at different depth levels, resulting in the mixing of soil samples at different depth levels, easily generating errors, and affecting the accuracy of geological environment monitoring.

A second adjusting ring 310 is threadedly connected to the second screw rod 309;

[0037] As Figures 6 to 8 shown, the sampling mechanism 5 includes a drill cylinder 51, a connecting seat 52, a sampling cylinder 53 and a connecting shaft 54.

[0040] The working process is as follows:

[0041] S1. During use, the operator steps on the bottom plate 101, then rotates the connecting frame 306 to align the observation mirror 307 on the connecting frame 306 with the drill cylinder 51 and the scale 103, and then tightens the first adjusting ring 305 and the second adjusting ring 310 to fix the position and angle of the observation mirror 307;

[0042] S2. Start the driving member 4. The driving member 4 drives the drill cylinder 51 to rotate through the connecting shaft 54. Loosen the fixing bolt 204 and rotate the crank 202. The crank 202 drives the gear 203 to rotate through the first rotating shaft 201. The gear 203 rotates on the rack 102, driving the first connecting frame 2 to slide on the column 1;

[0043] S3. When the sampling mechanism 5 contacts the ground, since the sampling cylinder 53 is located inside the drill cylinder 51, the bottom of the sampling cylinder 53 extends from the bottom of the drill cylinder 51. The sampling cylinder 53 first inserts into the ground. The first fixing plate 531 and the second fixing plate 533 limit the sampling cylinder 53 to prevent the sampling cylinder 53 from rotating with the rotation of the drill cylinder 51, reducing the relative movement between the soil and the sampling cylinder 53, thereby reducing the mutual friction between the sampling cylinder 53 and the soil entering the inside of the sampling cylinder 53, avoiding disturbing the soil at different depth levels and causing the soil samples at different depth levels to be mixed, thus avoiding errors and ensuring the accuracy of geological environment monitoring;

[0044] S4. Continue to rotate the crank 202 to insert the sampling mechanism 5 into the ground. The soil sample enters the sampling cylinder 53. The soil between the drill cylinder 51 and the sampling cylinder 53 is scraped and loosened by the guide plate 512. Part of the soil between the drill cylinder 51 and the sampling cylinder 53 moves along the guide plate 512 from the opening 511 to the outside of the drill cylinder 51;

[0045] S5. After sampling, remove the bolt between the connecting seat 52 and the drill cylinder 51. At this time, the drill cylinder 51 and the connecting seat 52 are no longer connected. Rotate the crank 202 in the reverse direction to raise the drill cylinder 51. When the drill cylinder 51 is pulled out of the ground, tighten the fixing bolt 204 to fix the position of the drill cylinder 51;

[0046] S6. Then move the drill cylinder 51 away from above the sampling cylinder 53, take out the connecting seat 52, the sampling cylinder 53 and the soil sample in the sampling cylinder 53 together from the hole drilled by the drill cylinder 51, and then open the side cover 532 from one side of the sampling cylinder 53 to take out the soil sample from the sampling cylinder 53.
