Geological disaster survey sampling device

Abstract

The invention discloses a geological disaster exploration sampling device, which belongs to the technical field of geological disaster exploration. Through the provision of a rotating mechanism and a sampling mechanism, etc., before sampling the moss, it is necessary to first rotate the sampler so that the sampler is rotated out from between a first half shell and a second half shell under the restriction of a first rotating shaft, and the extension distance of the sampler is adjusted according to the growth of the moss. At this time, the driving motor is started again. With the rotation of the driving motor, the rotating frame drives the sampler to rotate through the first rotating shaft and contact the substrate layer. With the continuous rotation of the sampler, the substrate layer is shoveled up together with the moss grown thereon, so that even when facing a harder substrate layer, it can be easily and quickly shoveled up. Moreover, since the sampler always rotates with the output shaft of the driving motor as the center of the circle, the depths of multiple samplings are the same, thereby ensuring the accuracy of the sample.

Description

Technical Field

[0001] The invention relates to the technical field of geological disaster exploration, and in particular to a geological disaster exploration sampling device. Background Art

[0002] Geological disaster survey is used to investigate, evaluate, predict and manage geological disasters in order to identify the potential and dangerous behaviors of geological disasters. After natural disasters such as earthquakes, mountain torrents, mud-rock flows and landslides, it is easy for the mountains to be exposed and the rock slopes to lose their original soil. It is necessary to carry out greening operations on the bare rock slopes without matrix after geological disasters.

[0003] Since bare rock slopes have no matrix environment, it is difficult for plants to survive if planted directly. Therefore, it is necessary to build an artificial matrix layer to provide the necessary soil conditions and nutrient support for plant growth, and plant pioneer plants to improve the soil texture. The most commonly used pioneer plants are various mosses that are suitable for the local ecological environment.

[0004] In order to analyze the state of land texture in time, managers need to regularly go to the greening area to sample mosses. Since mosses do not have true differentiation of roots, stems, and leaves, they are usually attached to the substrate through rhizomes or similar structures. Therefore, when sampling, the mosses need to be dug out completely together with their epiphytic substrates, so as to judge the restoration of land texture by the growth of the root system.

[0005] The depth of excavation varies from a few centimeters to more than ten centimeters, depending on the type and growth of the moss. The traditional sampling method is to use a knife or shovel to dig up the substrate layer and the moss together, but this sampling method is relatively slow, especially when the substrate layer is hard or the moss is widely distributed. It will consume a lot of time and energy, and the excavation depth is difficult to achieve uniformity. If the depth is too shallow, it is easy to directly damage the moss plant, especially its fragile leaves and rhizoids, while if the depth is too deep, it is easy to destroy the substrate layer and affect the restoration of the land texture at that location. Summary of the invention

[0056] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical geological disaster survey sampling device in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0057] In order to solve the problem that in the traditional sampling method, a knife or a shovel is used to dig up the substrate layer and the moss together, but this sampling method is relatively slow, especially when the substrate layer is hard or the moss is widely distributed, it will consume a lot of time and energy, and when multiple samplings are required, the depth of each sampling is difficult to achieve uniformity, and a too shallow depth is easy to directly damage the moss plant, while a too deep depth is easy to destroy the substrate layer and affect the accuracy of sample collection, the present invention proposes a geological disaster survey sampling device, such as Figure 1 - Fig.14 As shown:

[0058] The invention comprises a gripping portion 10, wherein the gripping portion 10 comprises a handle 11 for gripping, a support rod 12 arranged at the end of the handle 11, and two connecting portions 13 installed on the support rod 12, wherein the two connecting portions 13 are connected with a rotating mechanism 20, and the rotating mechanism 20 comprises a first half shell 21 and a second half shell 22 respectively connected with the two connecting portions 13, a discharge hole 211 is provided on the surface of the first half shell 21, a rotatable rotating frame 24 is arranged between the first half shell 21 and the second half shell 22, and at least one sampling mechanism 30 is equidistantly arranged on the rotating frame 24, a driving motor 25 is arranged on the first half shell 21, and a remote wireless control module and a control button (not shown in the figure) are arranged on the handle 11, and a control signal can be output to the driving motor 25 by gripping and pressing the button, so as to realize remote real-time control of the driving motor 25, and the output end of the driving motor 25 is connected to the rotating frame 24;

[0059] The rotating mechanism 20 further includes rotating rings 23 disposed on both sides of the rotating frame 24. Annular grooves are provided on both sides of the first half shell 21 and the second half shell 22. The rotating rings 23 on both sides of the rotating frame 24 are respectively rotatably embedded in the corresponding annular grooves.

[0060] When sampling is required, hold the handle 11 and make the first half shell 21 and the second half shell 22 fit on the ground. At this time, the sampling mechanism 30 is located directly above the moss to be sampled. At this time, the support rod 12 buffers the pressure applied by the first half shell 21 and the second half shell 22 on the matrix layer to avoid excessive pressure applied by the staff during the sampling process, causing the matrix layer to sink. At this time, press the remote control button on the handle 11 to make the drive motor 25 drive the rotating frame 24 to rotate. The rotating frame 24 drives the rotating rings 23 on both sides to rotate under the restriction of the first half shell 21 and the second half shell 22. The rotating frame 24 can drive the sampling mechanism 30 to rotate, and complete the sampling of the moss through the sampling mechanism 30.

[0061] like Figure 6-Figure 8 As shown, the sampling mechanism 30 includes a first rotating shaft 31 rotatably arranged on the rotating frame 24, a sampler 32 sleeved on the first rotating shaft 31, and a receiving cavity 33 arranged on the sampler 32. The sampler 32 can extend from between the first half shell 21 and the second half shell 22 and rotate with the rotating frame 24 to scoop up the moss and the substrate layer, and enter the receiving cavity 33 with the shoveling;

[0062] A vortex-shaped winder 34 is disposed inside the accommodating chamber 33, and the moss entering the accommodating chamber 33 contacts the winder 34 and curls;

[0063] A sampler 35 is embedded inside the winder 34. The sampler 35 includes a push plate 351 matched with the inner wall of the winder 34, a connecting rod 352 arranged in the middle of the push plate 351, and a cover 353 connected to the connecting rod 352 and capable of being embedded in a through hole opened on the accommodating cavity 33. When the push plate 351 moves, the curled moss in the winder 34 is pushed out.

[0064] A through hole is opened on one side of the accommodating chamber 33, and the moss is taken out when the accommodating chamber 33 rotates to the discharge hole 211;

[0065] Before sampling the moss, it is necessary to rotate the sampler 32 first so that the sampler 32 is rotated out from between the first half shell 21 and the second half shell 22 under the restriction of the first rotating shaft 31, and the extension distance of the sampler 32 is adjusted according to the growth of the moss. At this time, the drive motor 25 is started again. As the drive motor 25 rotates, the rotating frame 24 drives the sampler 32 to rotate through the first rotating shaft 31 and contact the substrate layer. As the sampler 32 continues to rotate, the substrate layer is shoveled up along with the moss grown thereon, so that even when facing a harder substrate layer, it can be easily and quickly shoveled up. Moreover, since the sampler 32 always rotates with the output shaft of the drive motor 25 as the center, the depth of multiple samplings is the same, thereby ensuring the accuracy of the sample.

[0066] After the moss sample is collected, it slides into the accommodating chamber 33 along with the sampler 32. At this time, under the guidance of the coiler 34 inside the accommodating chamber 33, the moss and the matrix layer can be curled into a vortex shape matching the coiler 34. The curled moss strip is more compact and easy to carry and transport. The gaps between the leaves are reduced, which reduces the movement of air on the leaf surface, helps to reduce the loss of water during the storage process, and maintains the activity of the moss. At the same time, after curling, the leaves can be tightly wrapped around the stem to protect the internal structure and ensure the integrity of the sample.

[0067] When it is necessary to remove the curly moss sample, such as Figure 8 and Fig. 9 As shown, a groove for pulling is provided on the cover body 353, and a countersunk hole (not shown in the figure) is provided on the inner wall of the side of the accommodating chamber 33 where no through hole is provided. The sampler 35 can be embedded in the countersunk hole. By pulling the groove, the cover body 353 drives the push plate 351 to move out of the countersunk hole through the connecting rod 352. The setting of the countersunk hole can ensure that the push plate 351 will not hinder the moss from entering the winder 34 for curling. At the same time, as the push plate 351 moves inside the winder 34, the push plate 351 contacts the curled moss sample and drives it to move out of the accommodating chamber 33. The curled moss sample after removal is sleeved on the connecting rod 352 and is taken out from the first half shell 21 through the discharge hole 211 along with the cover body 353. The staff can transfer the moss sample to a dedicated sample collection box for storage.

[0068] In order to be able to adjust the digging depth of the sampler 32 according to the growth of moss, Figure 7 , Figure 10-12 As shown, the excavation depth of the sampler 32 is adjusted by an adjustment mechanism 40, which includes a plurality of slide grooves 41 arranged on the rotating frame 24 and a slider 43 slidably embedded in the slide grooves 41, a threaded rod 42 is rotatably arranged in the slide groove 41, and the threaded rod 42 passes through the middle of the slider 43 and meshes with the slider 43;

[0069] The slider 43 is provided with a plurality of protrusions, and the inner wall of the slide groove 41 is provided with grooves that fit with the protrusions. With this design, the threaded rod 42 rotates and drives the slider 43 to move inside the slide groove 41. The protrusions on the slider 43 and the grooves on the inner wall of the slide groove 41 can cooperate with each other to limit the position of the slider 43, so that the slider 43 will not rotate with the threaded rod 42. The threaded rod 42 can only drive the slider 43 to move horizontally along the length direction of the slide groove 41.

[0070] The slider 43 is provided with a hinge 44, and a support rod 45 is rotatably provided on the hinge 44. The other end of the support rod 45 is connected to a hinge shaft 46 rotatably provided on the sampler 32. When the slider 43 moves, the support rod 45 pushes the sampler 32 to deflect around the first rotating shaft 31, so as to adjust the length of the sampler 32 extending from the first half shell 21 and the second half shell 22.

[0071] The position of the slider 43 is adjusted by rotating the threaded rod 42, so that the slider 43 pushes the support rod 45 through the hinge 44, and the support rod 45 pushes the sampler 32 to rotate around the first rotation axis 31 through the hinge shaft 46. The support rod 45 is always deflected during the pushing process to adjust the position;

[0072] As the rotating sampler 32 is able to extend from between the first half shell 21 and the second half shell 22 , the greater the extension distance, the deeper the excavation depth. When idle, the sampler 32 can be completely retracted into the first half shell 21 and the second half shell 22 by reverse rotation to avoid damage.

[0073] When the staff performs multiple sampling at the same location, it is necessary to adjust the positions of multiple samplers 32 synchronously, such as Figure 4 , Figure 7 and Fig.11 As shown, the ends of the plurality of threaded rods 42 all pass through the slide slots 41 and are provided with a driving mechanism 50, the driving mechanism 50 includes a driven bevel gear 54 sleeved on the plurality of threaded rods 42, and the driven bevel gear 54 is rotatably provided on the rotating frame 24;

[0074] A mounting frame 51 is mounted on the slide 41, and a servo motor 52 is mounted in the mounting frame 51. The opening and closing and the rotation direction of the servo motor 52 are also controlled by the remote control module on the handle 11. A driving bevel gear 53 that meshes with a plurality of driven bevel gears 54 is mounted on the output end of the servo motor 52.

[0075] By holding the handle 11 and pressing the remote control button, the servo motor 52 can be started. The servo motor 52 drives the active bevel gear 53 to rotate under the restriction of the mounting frame 51, so that the active bevel gear 53 can drive the multiple driven bevel gears 54 meshing with it to rotate synchronously, and the driven bevel gears 54 can drive the respectively connected threaded rods 42 to rotate, thereby achieving the purpose of synchronously adjusting the rotation angles of the multiple samplers 32, and the excavation depths of the multiple samplers 32 are the same.

[0076] When the number of samples to be sampled is large, in order to avoid the problem of insufficient number of samplers 35 leading to the need for repetition and the risk of sample contamination, the samplers 35 can be pre-stored in the storage mechanism 60, the storage mechanism 60 includes an arc-shaped storage cavity 61 arranged on the outer wall of the first half shell 21, the push plate 351 and the cover body 353 are respectively attached to the two sides of the inner wall of the storage cavity 61, and a gate plate 64 for blocking the samplers 35 is rotatably arranged at the entrance of the storage cavity 61;

[0077] A rotating cavity 62 is formed on the inner wall of the storage cavity 61, and a second rotating shaft 63 is rotatably provided on the rotating cavity 62. A gate plate 64 is sleeved and installed on the second rotating shaft 63, and the gate plate 64 can be completely embedded in the rotating cavity 62 by rotating.

[0078] Torsion springs 65 are wound around the two sides of the second rotating shaft 63, and the two ends of the torsion spring 65 are respectively connected to the gate plate 64 and the inner wall of the rotating chamber 62;

[0079] When it is necessary to place the sampler 35, the sampler 35 is attached to the gate plate 64 and pressed down, so that the gate plate 64 rotates under the restriction of the second rotating shaft 63 and pulls the torsion spring 65. The torsion spring 65 is elastically deformed due to the pulling, so that the gate plate 64 can be rotated and retracted into the rotating cavity 62, and the sampler 35 can enter the storage cavity 61 in turn, thereby completing the purpose of carrying multiple samplers 35. When it is necessary to take out the sampler 35 for use, use your fingers to push the gate plate 64 to rotate and open it, and offset the first half shell 21 so that the sampler 35 can roll against the inner wall of the storage cavity 61, so that it can roll out of the storage cavity 61.

[0080] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes to the technical geological disaster survey sampling device and its inventive concept according to the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
