Description

Technical Field

[0001] This invention relates to the field of geological sampling technology, specifically a novel sampler for geological environment monitoring. Background Technology

[0002] In fields such as geological exploration, mineral resource surveys, and engineering geological investigations, geological sampling is a crucial step in obtaining samples of underground rock strata, soil, and other media. As a core piece of equipment, the sampling efficiency, sample integrity, and operational flexibility of the sampler directly affect the accuracy of exploration data and the progress of the work.

[0003] Currently, geological samplers on the market are mainly divided into two categories: single-cylinder samplers and multi-cylinder samplers. Single-cylinder samplers have a simple structure and are suitable for single-point, small-scale sampling scenarios, but their sampling efficiency is low and it is difficult to meet the needs of large-area, multi-point simultaneous sampling. Multi-cylinder samplers, on the other hand, achieve multi-point simultaneous sampling by setting multiple sampling cylinders, which greatly improves sampling efficiency and is suitable for batch sampling operations. However, their structure is relatively complex, and when only single-point sampling is required, the redundant structure of the equipment will increase the difficulty of operation and transportation costs.

[0004] However, existing geological samplers generally suffer from fixed sampling methods. Single-tube and multi-tube sampling functions are independent of each other, making it difficult to switch flexibly according to actual exploration needs. For example, within the same exploration area, if some areas require precise single-point sampling while others require batch sampling at multiple points, operators must carry two different types of samplers. This not only increases equipment investment costs but also reduces operational flexibility and prolongs on-site operation time.

[0005] Meanwhile, the unloading process after sampling is a crucial step in ensuring sample integrity and the accuracy of subsequent testing. Existing samplers lack adaptability control for unloading methods and the number of sampling cylinders. For single-cylinder samplers, a single tapping structure is typically used for unloading, but this structure cannot meet the synchronous unloading requirements of multi-cylinder sampling scenarios. On the other hand, the unloading mechanism of multi-cylinder samplers is mostly a centralized control design, which can only achieve synchronous tapping unloading of all sampling cylinders, making it difficult to perform independent unloading operations on individual sampling cylinders.

[0006] In summary, existing geological samplers have significant shortcomings in terms of switching between single-tube and multi-tube sampling and the targeting and flexibility of material removal control, making it difficult to meet the diverse needs of geological exploration operations. Therefore, a new type of geological sampler that can achieve flexible switching of sampling methods and precise adaptation of material removal control is proposed to solve the existing problems. Summary of the Invention

A plurality of tooth limit blocks that mesh with the third gear are fixedly connected at equal intervals around the surface of the ring frame.

[0013] Preferably, the bottom of the edge pad is fixedly connected to a limiting sleeve by a bracket, a movable plate is slidably connected inside the limiting sleeve, and a first spring is fixedly connected between the movable plate and the limiting sleeve.

[0018] This invention provides a novel sampler for geological environment monitoring. Compared with existing technologies, it has the following advantages:

[0019] (1) The new sampler for geological environment monitoring, by setting up a sampling switching mechanism, a flexible matching mechanism for unloading and a receiving auxiliary mechanism inside the mounting frame, enables the device to switch flexibly between single-cylinder and multi-cylinder according to actual sampling needs through the coordinated cooperation of the sampling switching mechanism, the flexible matching mechanism for unloading and the receiving auxiliary mechanism.

[0020] (2) The new sampler for geological environment monitoring has an extended pad that is flush with the support frame on the top of the cross groove plate, and an auxiliary electric telescopic rod that fits against the top of the extended pad inside the mounting frame. This allows the extended end of the auxiliary electric telescopic rod to be directly attached to the main electric telescopic rod, thereby flexibly controlling its coordinated control mode with the main electric telescopic rod. This ensures that the stable thrust of single-cylinder and multi-cylinder sampling can be flexibly and stably switched on the basis of saving energy.

[0021] (3) The new sampler for geological environment monitoring, by rotating the stop bar on the surface of the limiting strip, allows the arc tooth extrusion ring to reciprocate by rotating and pushing the stop bar, and the stop bar can reduce the friction coefficient between the two through its self-rotation function, thereby improving the smoothness of the fit.

[0045] In a preferred embodiment, to facilitate auxiliary material receiving of the sampling cylinder 506 except at the center position, a material receiving auxiliary mechanism 7 is provided inside the mounting frame 1. The material receiving auxiliary mechanism 7 includes a ring frame 701, which is rotatably disposed inside the mounting frame 1. Several collars 702 are fixedly connected at equal intervals around the inner wall of the ring frame 701. A material receiving auxiliary cylinder 703 is slidably disposed inside the collars 702.

[0046] Several extended pads 11 are fixedly connected at equal intervals around the top of the cross groove plate 4.

[0047] Compared with Example 1, Example 2 has the following advantages: by setting an extended pad 11 flush with the bearing frame 3 on the top of the cross groove plate 4, and setting an auxiliary electric telescopic rod 12 that fits against the top of the extended pad 11 inside the mounting frame 1, the extended end of the auxiliary electric telescopic rod 12 can be flexibly controlled in a direct fitting manner to coordinate with the main electric telescopic rod 2, thereby ensuring a stable thrust for flexibly and stably switching between single-cylinder and multi-cylinder sampling while saving energy.

[0048] The specific operating steps are as follows:

[0049] Sampling Method 1, Single-Cylinder Sampling: The second servo motor 704 is pre-started, causing the second servo motor 704 to drive the third gear 705 to mesh with the tooth limit block 706, causing the tooth limit block 706 to control the ring frame 701 to rotate 45 degrees. During this process, the ring frame 701 will drive the receiving auxiliary cylinder 703 to be misaligned with the cross groove plate 4, providing an unobstructed channel for the descent of the cross groove plate 4.

[0050] Subsequently, the main electric telescopic rod 2 extends to drive the bearing frame 3, cross groove plate 4, electric telescopic rod 501 and center pad 502 to descend. The descent of the center pad 502 will drive the drive motor 505 and sampling cylinder 506 at its bottom to descend and approach the ground. During this process, the drive motor 505 is started, and the drive motor 505 drives the sampling cylinder 506 to rotate, causing the sampling cylinder 506 at the bottom of the center pad 502 to complete single-cylinder sampling.

[0051] Sampling and unloading: After the sampling cylinder 506 at the bottom of the central pad 502 returns to its original height, the first servo motor 601 is started. The first servo motor 601 drives the first gear 602 to rotate. The first gear 602 rotates and meshes with the gear ring 604. The gear ring 604 meshes with the second gear 605 at the same time, causing the L-shaped frame 606 to drive the striking rod 607 to move circumferentially. The striking rod 607 swings circumferentially and reciprocates to strike the sampling cylinder 506 at the bottom of the central pad 502.

[0052] Sampling Method 2, Multi-Cylinder Sampling: The second servo motor 704 is pre-started, causing the second servo motor 704 to drive the third gear 705 to mesh with the tooth limit block 706, causing the tooth limit block 706 to control the ring frame 701 to rotate 45 degrees. During this process, the ring frame 701 will drive the receiving auxiliary cylinder 703 to be misaligned with the cross groove plate 4, providing an unobstructed channel for the descent of the cross groove plate 4.

[0053] Then, the electric telescopic rod 501 is activated, causing the extended end of the electric telescopic rod 501 to drive the central pad 502 to fit tightly against the bottom of the cross groove plate 4, so that the central pad 502 and the edge pad 503 are on the same level, and the corresponding sampling cylinders 506 are all in a level state. When the central pad 502 is pulled up, it will push the edge pad 503 along the sliding groove at the bottom of the cross groove plate 4 through the inner groove plate 504 until the edge pad 503 moves to the bottom of the corresponding extended pad 11.

[0054] Then, the main electric telescopic rod 2 and the auxiliary electric telescopic rod 12 are started simultaneously. The main electric telescopic rod 2 and the auxiliary electric telescopic rod 12 drive the cross groove plate 4 to descend through the extension end. The descent of the cross groove plate 4 drives several drive motors 505 and sampling cylinders 506 to descend. During this process, the sampling cylinders 506 are driven to rotate synchronously by the drive motors 505 to collect samples.

[0055] Knocking linkage control: During the process of pushing the inner groove plate 504 to the equilibrium state by the center pad plate 502, the baffle 610 and the stop rod 611 synchronously return to the vertical state. When the baffle 610 returns to the vertical state, the first spring 10 inside the limit sleeve 8 will push the movable plate 9, the knocking frame 612 and the movable vertical plate 613 to move through tension until the movable vertical plate 613 is in contact with the surface of the baffle 610. When the stop rod 611 returns to the vertical state, it will enter the groove area of ​​the arc tooth extrusion ring 608.

[0056] Material unloading pre-acceptance: By reverse control of the second servo motor 704, the ring frame 701 is caused to reverse and reset the receiving auxiliary cylinder 703 to the bottom of the corresponding sampling cylinder 506;

[0057] Synchronous tapping for material removal: By starting the first servo motor 601, the first gear 602 meshes with the gear ring 604, and the gear ring 604 meshes with the second gear 605. The second gear 605 drives the tapping rod 607 to tap the sampling cylinder 506 at the bottom of the central pad 502 through the L-shaped frame 606. During the rotation of the gear ring 604, the arc tooth extrusion ring 608 is rotated synchronously. The protruding surface of the arc tooth extrusion ring 608 will continuously extrude the stop rod 611, causing the stop rod 611 to drive the baffle 610 to move back and forth through the limiting strip 609. The movement of the baffle 610 will push the movable vertical plate 613 back and forth, causing the movable vertical plate 613 to push the tapping frame 612 back and forth to tap the sampling cylinder 506 at the bottom of the edge pad 503. It should be noted that before centralized control material removal, a collection cylinder should be temporarily placed at the discharge point of the sampling cylinder 506 at the bottom of the central pad 502.
