Description

Technical Field

[0001] This invention relates to the field of rock observation technology, and more specifically to an auxiliary observation device for field geological rock identification that is easy to assemble and disassemble. Background Technology

[0002] Based on the identification and observation of geological rocks in the field, relevant information such as forecasting, prevention and elimination of geological disasters, investigation and development of geological landscapes, geological engineering design, and construction needs can be obtained by observing the shape and various property changes of the rocks. In fact, by using a special auxiliary observation device, the rocks can be effectively clamped and then the properties of the rocks can be identified and observed by combining a magnifying glass and laser detection. Therefore, the observation device can effectively complete the identification and observation of relevant rocks. In summary, the inventors have found that existing observation devices have the following main defects: due to the large overall size and weight of the current observation devices, they rely on their own weight to stabilize them in the field for identification and observation of relevant rocks. Therefore, simply using weight to fix the position can easily lead to instability of the observation location and make it difficult to move. At the same time, it does not meet the characteristics of easy disassembly and assembly, which reduces the convenience of using the observation device in the field and the accuracy of observation. Summary of the Invention

[0003] The technical solution adopted by the present invention to achieve the technical objective is: an auxiliary observation device for field geological rock identification that is easy to assemble and disassemble, the structure of which includes: a lightweight assembly and disassembly frame, a lightweight top plate, an electrical control board, a central column, and an observer.

The lower end of the clamping structure is connected to the center of the surface of the base plate and the left and right sides are matched with the anti-slip rods at intervals. The lower end of the anti-slip rods is also connected to an inserting block that passes through both sides of the base plate.

Then, the lower end of the anti-slip rod inserts the triangular interlocking block through the bottom plate into the soil. Subsequently, the clamping structure at the center of the surface layer can be connected to the center of the surface layer of the bottom plate through the connecting block of the solid block.

[0009] As a further improvement of the present invention, the left and right sides of the inner wall of the vertical plate are equipped with parallel support columns to determine the position of the parallel plate, and the surface of the parallel plate is planar and overlaps with the clamping block.

[0010] As a further improvement of the present invention, the clamping block is provided with a push-pull block, the push-pull block is welded to the lower center of the balance block, and a vertical slide rod is connected to the center of the surface of the balance block and the center is threadedly connected to the screw. A top block is fixed at the upper end of the screw and the outer layer of the top block is covered by a protective block.

[0011] As a further improvement of the present invention, the shape of the top block matches the shape of the protective block, and the screw at the lower end of the top block is locked vertically into the central internal thread connecting rail of the vertical slide rod.

[0012] As a further improvement of the present invention, the parallel block is provided with a rust-proof block body. The lower ends of the left and right sides of the rust-proof block body are provided with connecting grooves and the upper ends of the block body are provided with control blocks. The control blocks are matched with the limiting ring in the middle part. The limiting ring is set at the upper center of the rust-proof block body and covers the edge of the through groove in the middle. The through groove of the rust-proof block body matches the shape of the clamping block and is inserted and connected to one end of the support column through the connecting grooves at the lower ends of the left and right sides.

[0013] As a further improvement of the present invention, the rust-proof block is rectangular in shape and the connecting grooves on the left and right sides match the shape of the support column. A control block is provided on each side of the upper end of the rust-proof block. The through groove and the limiting ring are both circular in shape and match the shape of the clamping block.

[0014] As a further improvement of the present invention, the observer is provided with an assembly, which is installed at the upper center of the vertical box and the lower end of the vertical box includes a penetrating end. The observation cavity inside the vertical box is connected to the penetrating end. The positioning column is installed on the left and right sides inside the vertical box through the observation cavity to position the flexible contact body. The lower left and right sides of the flexible contact body include observers. The observers are electrically connected to the control board through the power line on the upper side of the flexible contact body.

[0015] As a further improvement of the present invention, the vertical box is formed into a "U" shape through the penetrating end, the positioning columns inside the observation cavity are set in mutually symmetrical positions to fix the left and right sides of the flexible contact body, the observer is semi-circular in shape and includes a magnifying glass and a laser detector, and the assembly is square in shape and matches the shape of the telescopic rod at the lower end of the central column.

[0016] As a further improvement of the present invention, the assembly is provided with an overlapping plate, a locking block is fixed in the center of the overlapping plate and straight plates are connected to the upper and lower edges, and bolts are connected in the straight plates to complete the splicing with the lower part of the central telescopic rod inside the central column.

[0017] As a further improvement of the present invention, the overlapping plate is square in shape and its center is perpendicular to the card block. Three bolts are connected in the middle of the straight plate and are connected through the left, middle and right ends.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention is based on a lightweight assembly / disassembly frame and a lightweight top plate. The weight of the overall device can be reduced by utilizing the properties of aluminum alloy. The two base plates of the lightweight assembly / disassembly frame can be connected to the lightweight top plate through the adsorption blocks and protrusions at the upper end of the anti-slip rod, which facilitates on-site assembly and disassembly. Furthermore, the triangular interlocking block at the lower end of the anti-slip rod can be inserted into the soil for fixation, allowing the observer to be aligned with the rock position. Therefore, this invention can effectively improve the stability of the device for rock observation and meet the requirements of easy assembly and disassembly on-site.

[0019] 2. The present invention further improves the clamping structure on the base plate. The connecting block and the solid block enable the vertical plate to be stably connected to the center of the base plate. Then, the vertical support determines the position of the parallel plate, so that the clamping block can control the vertical slide rod to drive the top block to slide through the push-pull block. For this purpose, after the top block contacts the edge of the rock through the protective block, the position of the rock can be clamped and determined, further improving the matching degree between the observer and the center of the rock.

[0020] 3. The present invention further improves upon the parallel plate by using the connecting grooves at the lower ends of the left and right sides of the anti-rust block to match the shape of one end of the support column on the vertical plate. Then, it can overlap with the vertical plate by direct embedding. Therefore, the effect of easy on-site disassembly and assembly can be achieved by direct embedding or by pulling out the control block.

[0021] 4. With further improvements to the observer, the position of the flexible contact body can be determined by the positioning column in the vertical box. This allows the flexible contact body to deform under force after being vertically embedded in the rock through the penetrating end. Therefore, the observer in the edge area can contact the rock surface. Subsequently, close-range magnification and laser detection can improve the accuracy of rock identification.

Detailed Implementation

[0030] The present invention will be further described below with reference to the accompanying drawings: Example

[0031] Figures 1 to 5 As shown: This invention provides an easy-to-assemble and disassemble auxiliary observation device for field geological rock identification. Its structure includes a lightweight assembly / disassembly frame 1, a lightweight top plate 2, an electrical control board 3, a central column 4, and an observer 5. The upper end of the lightweight assembly / disassembly frame 1 is connected to the lower left and right surfaces of the lightweight top plate 2, and the electrical control board 3 is installed on the upper side of the lightweight top plate 2 and is spaced to the central column 4. The central column 4 passes through the center of the lightweight top plate 2 and is connected to the upper center of the observer 5.

[0032] The lightweight assembly / disassembly frame 1 is provided with a clamping structure 16. The lower end of the clamping structure 16 is connected to the center of the surface of the base plate 14 and the left and right sides are spaced together with the anti-slip rod 13. The lower end of the anti-slip rod 13 is also connected to an inserting block 15 that passes through both sides of the base plate 14. The upper end of the anti-slip rod 13 carries an adsorption block 12 and a protrusion 11.

[0033] The clamping structure 16 is provided with a clamping block 166, which is located at the center of the surface of the parallel plate 165. The left and right sides of the parallel plate 165 are installed in the center area of ​​the vertical plate 163 by the support column 164. The lower end of the vertical plate 163 is equipped with a solid block 162 and a connecting block 161.

[0034] In this process, the adsorption block 12 and protrusion 11 at the upper end of the anti-slip plate 13 of the lightweight disassembly frame 1 complete the interpenetrating adsorption connection with the lower edge of the lightweight top plate 2. Then, the triangular interpenetrating block 15 through the bottom plate 14 at the lower end of the anti-slip rod 13 is inserted into the soil. Subsequently, the clamping structure 16 at the center of the surface layer can complete the parallel interpenetrating connection with the center of the surface layer of the bottom plate 14 through the connecting block 161 of the solid block 162. Then, the edge of the rock is limited by the clamping block 166 of the vertical plate 163.

[0035] The lightweight assembly / disassembly frame 1 and the lightweight top plate 2 are both made of aluminum alloy. The lightweight assembly / disassembly frame 1 has two sets at the lower end of the lightweight top plate 2. The central column 4 is perpendicular to the observer 5, and the central column 4 also carries a telescopic rod inside to adjust the height of the observer 5.

[0036] The protrusion 11 and the adsorption block 12 are both solid, and the surface of the lower anti-slip rod 13 is covered by a rubber sleeve. The insertion block 15 at the lower end of the anti-slip rod 13 is triangular and sharp. The clamping structure 16 and the base plate 14 are both provided with two sets and set in a symmetrical position.

[0037] The vertical plate 163 has parallel support columns 164 on both sides of its inner wall to determine the position of the parallel plate 165. The surface of the parallel plate 165 is planar and overlaps with the clamping block 166.

[0038] The clamping block 166 is provided with a push-pull block 1661, which is welded to the lower center of the balance block 1662. The center of the surface of the balance block 1662 is also connected to a vertical slide rod 1663, which is threadedly connected to the screw 1664. The upper end of the screw 1664 is fixed with a top block 1665, and the outer layer of the top block 1665 is covered by a protective block 1666.

[0039] The top block 1665 is shaped to match the protective block 1666, and the screw 1664 at the lower end of the top block 1665 is locked vertically into the central internal threaded connecting rail of the vertical slide bar 1663.

[0040] The parallel block 165 is provided with a rust-proof block 1651. The lower ends of the left and right sides of the rust-proof block 1651 are provided with connecting grooves 1652 and the upper ends are provided with control blocks 1653. The control blocks 1653 are matched with the limiting ring 1655 in the middle. The limiting ring 1655 is located at the upper center of the rust-proof block 1651 and covers the edge of the through groove 1654 in the middle. The through groove 1654 of the rust-proof block 1651 matches the shape of the clamping block 166 and is inserted and connected to one end of the support column 164 through the connecting grooves 1652 at the lower ends of the left and right sides.

[0041] The rust-proof block 1651 is rectangular in shape, and the connecting grooves 1652 on the left and right sides match the shape of the support column 164. The control block 1653 is provided on each side of the upper end of the rust-proof block 1651. The through groove 1654 and the limiting ring 1655 are both circular in shape and match the shape of the clamping block 166.

[0042] The specific functions and operation procedures of this embodiment are as follows: In this invention, the field geological rock identification auxiliary observation device can be assembled and disassembled on-site using a lightweight assembly / disassembly frame 1 and a lightweight top plate 2. This allows the lightweight assembly / disassembly frame 1 to be easily connected to the lower edge of the lightweight top plate 2 via the adsorption blocks 12 and protrusions 11 on the upper ends of the anti-slip rods 13 on the two sets of base plates 14, facilitating subsequent assembly and disassembly. Furthermore, the triangular interlocking block 15, which penetrates the base plate 14 at the lower end of the anti-slip rod 13, can be inserted into the field surface using its own shape. In the external soil, the soil's moisture and coverage ensure that the device is vertically positioned for use in the field, improving the stability of rock observation and identification. Then, the telescopic rod inside the central column 4 at the center of the lightweight top plate 2 can extend the observer 5 via the electronic control board 3, allowing the observer 5 to observe and identify relevant rocks. Subsequently, the clamping structure 16 on the bottom plate 14 can connect to the center of the surface of the bottom plate 14 via the connecting block 161 at the lower end of the solid block 162. Then, the solid block 162... The vertical plate 163 can be inserted and overlapped with the support column 164 through the connecting groove 1652 of its own rust-proof block 1651 for restraint. During the process, it can be manually removed and placed through the control block 1653, which improves the ease of disassembly and assembly. Furthermore, the through groove 1654 and the limiting ring 1655 in the central part can allow the clamping block 166 of the clamping structure 16 to move in a parallel linear motion. The clamping block 166 can be manually pushed by the push-pull block 1661 to drive the vertical slide rod 1663 of the balance block 1662, thereby moving the top block 1665 and the protective block 1666. The vertical sliding rod 1663 can penetrate through the through groove 1654 and the limiting ring 1655 area, which improves the parallel sliding effect. Then, by clamping the edge of the rock with the top block 1665 and the protective block 1666, the center fit between the rock and the observer 5 can be improved, preventing tilting and ensuring that the observer 5 can completely cover the rock, thus further improving the accuracy of rock observation and identification. At the same time, the rubber protective block 1666 on the top block 1665 can directly contact the rock surface, which can prevent scratching of the rock surface caused by metal-to-metal contact. Example

[0043] Figures 6 to 7 As shown: This invention provides an easy-to-assemble and disassemble auxiliary observation device for field geological rock identification. Its structure includes an observation device 5 with an assembly 58, which is installed at the upper center of a vertical box 51. The lower end of the vertical box 51 includes a penetrating end 52. The observation cavity 53 inside the vertical box 51 communicates with the penetrating end 52. The positioning column 54 is installed on the left and right sides inside the vertical box 51 through the observation cavity 53 to position the flexible contact body 55. The lower left and right sides of the flexible contact body 55 include observation devices 56. The observation devices 56 are electrically connected to the control board 3 through the power line 57 on the upper side of the flexible contact body 55.

[0044] The vertical box 51 is formed into a concave shape through the penetrating end 52. The positioning columns 54 inside the observation cavity 53 are set in mutually symmetrical positions to fix the left and right sides of the flexible contact body 55. The observer 56 is semi-circular and includes a magnifying glass and a laser detector. The assembly 58 is square and matches the shape of the telescopic rod at the lower end of the central column 4.

[0045] The assembly 58 is provided with an overlapping plate 581. A locking block 582 is fixed in the center of the overlapping plate 581, and straight plates 583 are connected to the upper and lower edges. Bolts 584 are connected to the straight plates 583 to complete the splicing with the lower part of the central telescopic rod inside the central column 4.

[0046] The overlapping plate 581 is square in shape and its center is perpendicular to the card block 582. Three bolts 584 are connected in the straight plate 583 and are connected through the left, middle and right ends.

[0047] The specific functions and operation procedures of this embodiment are as follows: In this invention, the vertical box 51 of the observer 5 can be installed in the lower area of ​​the central telescopic rod inside the central column 4 through the locking block 582 in the overlapping plate 581 of the upper mounting accessory 58. At the same time, it is locked by the left, middle and right bolts 584 in the edge straight plate 583 to achieve a firm fit. The detachable design also facilitates easy assembly and disassembly. Then, the bottom penetrating end 52 of the vertical box 51 allows the rock to penetrate into the observation cavity 53 area. For this purpose, the top of the rock will contact the lower layer of the flexible contact body 55 positioned by the positioning column 54. The flexible contact body 55 will then deform under the pressure of the rock. At the same time, the observer 56 in the edge area can contact the rock surface. Utilizing its local magnification characteristics and the laser detection effect it carries, the detected image and the rock data detected by the laser can be transmitted to the control board 3 through the power line 57. Therefore, it can further improve the accuracy of the overall rock data identification and observation, and improve the overall usability of the observation device.
