Description

Technical Field

[0001] This invention relates to the field of soil sampling technology, and in particular to a geological surveying and sampling device. Background Technology

[0002] Geological mapping is a science used to study underground structures, material composition, and geological evolution processes. Sampling soil samples is an indispensable part of geological mapping, providing detailed geological information and supporting a range of engineering decisions and environmental protection measures.

[0003] The existing soil sampling equipment is a soil sampler. During sampling, the operator moves the soil sampler downwards along the axis of the sampling drill and rotates it around the axis to complete the soil sampling. In actual sampling, the operator found that the soil core inside the sampling drill is prone to circumferential displacement, which affects the soil layer distribution and leads to sample distortion. Summary of the Invention

[0004] Research and analysis revealed that the circumferential displacement of the core sample inside the sampling drill tube is due to the frictional force between the core soil and the drill tube after the soil enters the tube. The core soil rotates synchronously with the drill tube, while the soil not inside remains stationary. Therefore, at the interface between the core soil and the non-core soil, circumferential displacement occurs due to the velocity difference. Based on this, it is necessary to provide a geological mapping sampling device to address the problems of current soil samplers and solve the issue of soil displacement and deformation relative to the inner wall of the sampling drill tube during the sampling process.

Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0058] likeFigures 1 to 13 As shown in the drawings, a geological survey sampling device includes a base 100, a drill barrel 300, a fixed barrel 400, a first rotating ring 510 and a second rotating ring 520, the drill barrel 300 is arranged on the base 100, the drill barrel 300 can rotate around its axis and move along its axis, the fixed barrel 400 is arranged on the base 100, and the fixed barrel 400 is located inside the drill barrel 300, the first rotating ring 510 and the second rotating ring 520 are both multiple, the inner diameters of the first rotating ring 510 and the second rotating ring 520 are the same, the multiple first rotating rings 510 and the multiple second rotating rings 520 are rotationally arranged in the fixed barrel 400 and are alternately arranged from bottom to top along the axis of the fixed barrel 400, the lowermost first rotating ring 510 or the second rotating ring 520 is coaxially fixedly connected with the drill barrel 300 (the drill barrel 300 is coaxially fixedly connected with the first rotating ring 510 as shown in the middle), Figure 4 The first transmission assembly 600 is arranged between adjacent first rotating rings 510 and second rotating rings 520, and is used to make the rotation directions of the first rotating rings 510 and the second rotating rings 520 opposite when the first rotating rings 510 and the second rotating rings 520 rotate at the same time.

[0059] When sampling the soil in a certain area, the staff moves the base 100 to the area to be sampled, so that the center of the drill barrel 300 is aligned with the sampling point, then the drill barrel 300 is circumferentially rotated and moved downward along its axis, at this time the drill barrel 300 drives the lowermost first rotating ring 510 to rotate synchronously, under the transmission action of the first transmission assembly 600, the second rotating ring 520 adjacent to the lowermost first rotating ring 510 also rotates at the same time, and the rotation direction of the second rotating ring 520 is opposite to that of the first rotating ring 510, and for the same reason, under the transmission action of the first transmission assembly 600, the remaining first rotating rings 510 and the second rotating rings 520 also rotate at the same time, and the rotation directions of adjacent first rotating rings 510 and second rotating rings 520 are opposite, when the drill barrel 300 moves downward to contact the soil, as the drill barrel 300 continues to move downward, the soil gradually enters the inside of the drill barrel 300 (here the soil entering the inside of the drill barrel 300 is defined as a sample core), when the outer peripheral surface of the sample core contacts the first rotating ring 510 and the second rotating ring 520 at the same time, because the rotation directions of the first rotating ring 510 and the second rotating ring 520 are opposite, the torsional forces applied to the sample core by the first rotating ring 510 and the second rotating ring 520 are the same in size and opposite in direction, therefore, in the case that the number of the first rotating ring 510 and the second rotating ring 520 contacting the sample core is the same, the circumferential force of the sample core is balanced, avoiding the displacement of the sample core in the circumferential direction due to the excessive circumferential torsional force, thereby ensuring that the soil layer distribution of the sample core as much as possible truly reflects the real soil layer distribution of the area.

[0060] After sampling is completed, the staff stops the drill cylinder 300 from rotating and moves it in the opposite direction so that the drill cylinder 300 carrying the sample core can be removed from the soil. After the drill cylinder 300 is removed from the soil, the staff gently taps the drill cylinder 300 with a rubber mallet so that the sample core inside the drill cylinder 300 can slide out.

[0061] In this embodiment, as Figure 4 and Figure 5 As shown, the first transmission assembly 600 includes a first gear ring 610, a second gear ring 620, and a reversing gear 630. In the adjacent first rotating ring 510 and second rotating ring 520, the first gear ring 610 is coaxially disposed on the outer peripheral wall of the first rotating ring 510, and the second gear ring 620 is coaxially disposed on the outer peripheral wall of the second rotating ring 520. The reversing gear 630 is rotatably disposed on the inner peripheral wall of the fixed cylinder 400. The upper part of the reversing gear 630 meshes with the first gear ring 610, and the lower part of the reversing gear 630 meshes with the second gear ring 620.

[0062] When the drill barrel 300 drives the lowest first rotating ring 510 to rotate synchronously, the first rotating ring 510 drives the corresponding reversing gear 630 to rotate through the first toothed ring 610 set on its outer periphery. The reversing gear 630 drives the second rotating ring 520 to rotate through the second toothed ring 620 meshing with it. Since the first rotating ring 510 and the second rotating ring 520 are coaxial, and the axis of the reversing gear 630 is perpendicular to the axis of the first rotating ring 510, the first rotating ring 510 and the second rotating ring 520 rotate simultaneously and in opposite directions.

[0063] In this embodiment, as Figure 4 and Figure 6 As shown, the inner circumferential wall of the first rotating ring 510 is provided with a plurality of first connecting rods 511 at equal intervals in the circumferential direction. The plurality of first connecting rods 511 extend radially along the first rotating ring 510. The end of the first connecting rod 511 away from the first rotating ring 510 is fixedly connected to a first inner ring 512. The inner circumferential wall of the second rotating ring 520 is provided with a plurality of second connecting rods 521 at equal intervals in the circumferential direction. The plurality of second connecting rods 521 extend radially along the second rotating ring 520. The end of the second connecting rod 521 away from the second rotating ring 520 is fixedly connected to a second inner ring 522. The diameter of the second inner ring 522 is the same as the diameter of the first inner ring 512.

[0064] It is understandable that the soil in the outer periphery of the sample core is more prone to displacement than the soil in other areas because it is in direct contact with the inner circumferential surfaces of the first rotating ring 510 and the second rotating ring 520. This will still cause some distortion of the sample. To solve this problem, in this embodiment, the sample core is divided into inner and outer layers by setting the first inner ring 512 and the second inner ring 522. Taking the first inner ring 512 as an example, during testing, the staff only takes the inner layer sample core as the target sample core, and the outer layer sample core is directly discarded. This is because the first rotating ring 510 and the second inner ring 520 are in direct contact with the inner circumferential surfaces of the first rotating ring 510 and the second inner ring 520. The first inner ring 512 has the same angular velocity, but its diameter is smaller than that of the first rotating ring 510. Therefore, the linear velocity of the first rotating ring 510 is greater than that of the first inner ring 512. Consequently, the outer core sample in contact with the first rotating ring 510 moves a greater distance than the inner core sample in contact with the first inner ring 512. Thus, the soil displacement in the outer periphery of the inner core sample is less than that in the outer periphery of the outer core sample. Therefore, using the inner core sample as the target core helps ensure that the soil layer distribution of the core sample accurately reflects the actual soil layer distribution in the area. The second inner ring 522 operates on the same principle as the first inner ring 512, and the specific process will not be elaborated further.

[0065] It should also be noted that the first connecting rod 511 serves two purposes. Firstly, it connects the first rotating ring 510 and the first inner ring 512. Secondly, it cuts the outer core sample into multiple segments via the first connecting rod 511, causing the first rotating ring 510 corresponding to the cut outer core sample to rotate as well, thereby reducing the resistance to the rotation of the drill barrel 300. The second connecting rod 521 serves the same purpose, and will not be elaborated further.

[0066] In this embodiment, as Figure 4 , Figure 6 , Figures 8-10 As shown, an annular gap 530 is provided between adjacent first inner ring 512 and second inner ring 522. Multiple arc-shaped plates 540 are arranged circumferentially and at equal intervals in the annular gap 530. The multiple arc-shaped plates 540 can move up and down synchronously along the axis of the annular gap 530. When the multiple arc-shaped plates 540 move upward along the axis of the annular gap 530, the multiple arc-shaped plates 540 move radially and synchronously closer to the axis of the annular gap 530, so that the multiple arc-shaped plates 540 form a ring circumferentially, and the diameter of the ring is adapted to the diameter of the first inner ring 512. When the multiple arc-shaped plates 540 move downward along the axis of the annular gap 530, the multiple arc-shaped plates 540 move radially and synchronously away from the axis of the annular gap 530, so that the multiple arc-shaped plates 540 separate from each other.

[0067] It is understandable that the soil core sample entering the drill barrel 300 is subjected to a frictional force in addition to the force acting on its circumference, as well as a frictional force acting downward along its axial direction (specifically, taking the drill barrel 300 as a reference, the soil core sample moves upward along its axis, so the frictional force acting on the soil core sample is downward, and this frictional force will cause the core sample to shift along its axis). Therefore, in order to reduce the amount of displacement of the core sample in its axial direction, it is necessary to make the core sample subject to a frictional force acting upward along its axial direction. In this way, by making the two frictional forces acting on the core sample cancel each other out, the amount of displacement of the core sample in its axial direction can be reduced.

[0068] As the drill barrel 300 continues to drill into the soil, multiple arc-shaped plates 540 move up and down synchronously. When the multiple arc-shaped plates 540 move upward synchronously, they simultaneously approach the axis of the annular gap 530 radially, so that the multiple arc-shaped plates 540 form a ring around the circumference, and the diameter of the ring matches the diameter of the inner core sample. Therefore, the multiple arc-shaped plates 540 simultaneously come into contact with the inner core sample and move upward relative to the inner core sample along its axis (with the arc-shaped plate 540 as a reference, the inner core sample moves downward, and at this time the frictional force on the inner core sample from the arc-shaped plate 540 is directed upward along its axis). This allows the two frictional forces on the inner core sample to cancel each other out, so as to reduce its displacement in the axial direction.

[0069] As the arc-shaped plate 540 moves downward, multiple arc-shaped plates 540 simultaneously move away from the axis of the annular gap 530 radially, thus separating the multiple arc-shaped plates 540 from each other. At this time, the inner circumferential surfaces of the multiple arc-shaped plates 540 no longer contact the outer circumferential surface of the inner core sample, and the inner core sample is no longer subject to frictional force from the arc-shaped plates 540. As the arc-shaped plate 540 moves up and down reciprocally, the inner core sample is intermittently subject to frictional force from the arc-shaped plate 540, so as to reduce the displacement of the inner core sample in its axial direction during sampling, thereby ensuring that the soil layer distribution of the core sample reflects the true soil layer distribution of the area as accurately as possible.

[0070] In this embodiment, as Figures 4-11As shown, a second transmission assembly 700 is provided between the first rotating ring 510 and the arc plate 540. The second transmission assembly 700 is used to drive multiple arc plates 540 to reciprocate up and down along the axis of the annular gap 530. The second transmission assembly 700 includes an annular spiral 710, an intermediate limiting ring 720, a guide post 730, and a guide bar 740. The annular spiral 710 is coaxially arranged on the inner peripheral wall of the first rotating ring 510. A spiral groove is formed on the inner peripheral wall of the annular spiral 710. The spiral groove includes multiple rising sections 711 and multiple falling sections 712. The multiple rising sections 711 and multiple falling sections 712 are alternately connected to form a ring, wherein the groove depth of the rising section 711 is less than that of the falling section 712. The groove depth of the descending section 712, the transition slope 713 is provided at the junction of the ascending section 711 and the descending section 712, there are multiple guide posts 730, one end of the multiple guide posts 730 is set on the outer peripheral surface of the corresponding arc plate 540, and the other end of the multiple guide posts 730 slides through the intermediate limiting ring 720 and is slidably connected in the spiral groove. There are multiple guide strips 740, and the multiple guide strips 740 are correspondingly set on the upper end of each arc plate 540. The first inner ring 512, the second inner ring 522 and the upper part of the fixed cylinder 400 are provided with guide grooves 750, the guide grooves 750 extend along the axis of the annular gap 530, and the guide grooves 750 slide with the guide strips 740.

[0071] As the drill barrel 300 continues drilling into the soil, the first rotating ring 510 rotates under force, driving the connected annular spiral strip 710 to rotate synchronously. Since the guide post 730 is slidably connected within the spiral groove, when the annular spiral strip 710 rotates until the guide post 730 slides to the lower end of the rising section 711 of the spiral groove, the guide post 730 slides upward along the rising section 711 as the annular spiral strip 710 continues to rotate. At this time, the guide post 730 drives the corresponding arc-shaped plate 540 to move upward synchronously. Because the groove depth of the rising section 711 is less than the groove depth of the descending section 712, under the limiting action of the guide post 730 and the groove of the rising section 711, the adjacent arc-shaped plates 540 overcome the mutual magnetic repulsion, thus circumferentially... As the first rotating ring 510 continues to rotate, the guide post 730 gradually slides from the rising section 711 to the falling section 712. Since the groove depth of the rising section 711 is less than that of the falling section 712, when the guide post 730 slides into the falling section 712, the adjacent arc-shaped plates 540 move away from each other under the action of mutual magnetic repulsion until the reversing gear 630 contacts the bottom of the groove in the falling section 712. As the first rotating ring 510 continues to rotate, the guide post 730 gradually moves to the lower end of the falling section 712. At this time, under the guidance of the transition slope 713, the guide post 730 slides from the falling section 712 to the rising section 711, thus causing the guide post 730 to drive the corresponding arc-shaped plate 540 to move up and down reciprocally. The up and down reciprocating movement of the arc-shaped plate 540 corresponding to the second rotating ring 520 is the same as that of the arc-shaped plate 540 corresponding to the first rotating ring 510, and will not be described in detail here.

[0072] It should also be noted that, in order for the outer sample core to be able to enter between the first rotating ring 510 and the first inner ring 512, and between the second rotating ring 520 and the second inner ring 522, the annular spiral 710 and the first rotating ring 510 should be fixedly connected by a transverse connecting plate 760, and the annular spiral 710 and the second rotating ring 520 should also be fixedly connected by a transverse connecting plate 760.

[0073] It should also be noted that an intermediate limiting ring 720 is installed to prevent soil from entering the spiral groove.

[0074] In this embodiment, as Figure 1 As shown, the base 100 includes a base and a support plate 200. The support plate 200 is located above the base, and the drill barrel 300 is rotatably disposed below the support plate 200. The support plate 200 can move relative to the base along the axis of the drill barrel 300.

[0075] In this embodiment, as Figure 1 and Figure 2As shown, a first drive assembly 800 is provided at the lower part of the support plate 200. The first drive assembly 800 is used to drive the drill barrel 300 to rotate circumferentially. The first drive assembly 800 specifically includes a first motor 810, a drive gear 820 and a third gear ring 830. The first motor 810 is provided on the support plate 200. The output shaft of the first motor 810 passes through the support plate 200, and the drive gear 820 is fixedly connected to one end of the output shaft of the first motor 810 passing through the support plate 200. The third gear ring 830 is coaxially provided on the outside of the drill barrel 300 and meshes with the drive gear 820.

[0076] When in use, start the first motor 810, which drives the drive gear 820 to rotate. The drive gear 820 then drives the drill barrel 300 to rotate via the third gear ring 830.

[0077] In this embodiment, as Figure 1 and Figure 2 As shown, a second drive assembly 900 is provided between the base 100 and the support plate 200. The second drive assembly 900 is used to drive the support plate 200 to move along the axis of the drill barrel 300. The second drive assembly 900 includes a second motor 910, a screw 920 and a limiting post 930. The second motor 910 is mounted on the base. The output shaft of the second motor 910 is fixedly connected to the screw 920. The screw 920 is threadedly connected to the support plate 200. There are multiple limiting posts 930, and the lower ends of the multiple limiting posts 930 are spaced apart on the base.
