Description

Technical Field

[0001] This invention belongs to the field of surveying benchmark technology, specifically relating to a portable surveying benchmark for geological exploration. Background Technology

[0002] In geological exploration scenarios such as mineral exploration, engineering geological survey, and topographic mapping, surveying benchmarks serve as core tools for determining the coordinates of measuring points and establishing elevation datums. Their stability, adaptability, and data reliability directly determine the accuracy of the exploration results. However, existing surveying benchmarks are limited by their structural design and cannot meet the actual needs of complex exploration environments. The main shortcomings are concentrated in the following two aspects: First, the terrain adaptability is poor and the support stability is insufficient. The existing benchmark support structure is simple. The fixed metal cone tip is only suitable for ordinary soil and is prone to settlement and tilting in soft soil. The flat plate base is only suitable for hardened ground and is easily pushed away by external forces on smooth rock surfaces. When facing complex terrains such as mountain slopes and piles of gravel, the single support mode is difficult to fix effectively, which directly affects the positioning accuracy and cannot meet the requirements of high-precision survey.

[0003] Secondly, the calibration efficiency is low and the data recording mode is outdated. Verticality calibration relies on external equipment, which is difficult for a single person to operate. Some integrated bubble level poles can only be roughly calibrated, resulting in a long deployment time. At the same time, the poles only serve as physical references. The coordinates of the measuring points need to be measured by external equipment, the tilt angle needs to be read manually, and the data needs to be recorded or entered manually. Omissions and errors can easily lead to mismatches between the coordinates and the tilt state, which greatly reduces the efficiency of the operation.

[0004] In summary, to address the aforementioned issues, there is an urgent need for a modular, portable surveying benchmark with multi-terrain adaptive support and automatic data acquisition capabilities. Summary of the Invention

[0005] In view of the above-mentioned shortcomings in the prior art, the present invention provides a portable surveying benchmark for geological exploration to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A portable surveying pole for geological exploration includes a modular pole assembly. An adjustment device is threadedly connected to the lower side of the modular pole assembly, and a support device is threadedly connected to the lower side of the adjustment device. The support device includes a connecting component threadedly connected to the adjustment device, and a triangular component on the lower side of the connecting component. The adjustment device includes a universal joint shaft threadedly connected to the modular pole assembly. A fixing block is located on the lower side of the universal joint shaft, and a retaining ring is located on the lower side of the fixing block, inside a fixed cylinder. Multiple threaded shafts are located on the upper side of the fixed cylinder, and adjusting bushings are mounted on the threaded shafts. A movable groove is located on the upper side of the fixed cylinder.

[0007] Furthermore, the module rod assembly includes a main rod connected to a universal joint shaft, a first auxiliary rod threadedly connected to the upper side of the main rod, a second auxiliary rod threadedly connected to the first auxiliary rod, a rod end cap provided on the second auxiliary rod, an mounting plate provided on the inner wall of the main rod, a positioning module provided on the upper side of the mounting plate, and an angle sensor provided on the lower side.

[0008] Furthermore, the connecting assembly includes a connecting shaft with a fixed cylindrical thread connection, a main cone on the lower side of the connecting shaft, and multiple corner mounting blocks on the outer side of the main cone.

[0009] Furthermore, the triangular assembly includes a hinge plate fixedly connected to the corner mounting block, fixed shafts on both sides of the hinge plate, a sliding plate slidably connected between the fixed shafts, a corner fixing plate on the sliding plate, a cone tip receiving groove on one side of the sliding plate, a supporting cone tip in the cone tip receiving groove, a locking shaft on the supporting cone tip, and a supporting plate hinged to the lower side of the sliding plate.

[0010] Furthermore, the universal joint shaft passes through the movable groove, the bottom of the universal joint shaft is spherical, the sphere is adapted to the fixed block, the upper inner wall of the fixed cylinder is adapted to the bottom sphere of the universal joint shaft, and the fixed cylinder is connected to the retaining ring.

[0011] Furthermore, the positioning module and the tilt sensor are connected to the handheld terminal via a wireless module.

[0012] Furthermore, the main rod is equipped with a battery, which is electrically connected to the positioning module and the tilt sensor. The main rod, the first auxiliary rod, and the second auxiliary rod are coated with a scratch-resistant and wear-resistant coating.

[0013] Furthermore, the fixed shaft has a threaded hole on its side, and a fixing bolt is installed in the threaded hole.

[0014] Furthermore, the locking shaft passes through the slide plate, and the bottom of the locking shaft is connected to the support cone tip, which is slidably connected to the cone tip receiving groove.

[0015] Furthermore, the triangular component has three sets of corresponding corner mounting blocks, and the three sets of triangular components are evenly distributed circumferentially, while the threaded shaft is evenly distributed circumferentially along the fixed cylinder.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The support device uses three sets of circumferentially evenly distributed triangular components, combined with a pull-out support cone and a flip-up support plate, to achieve support switching in multiple scenarios. In soft soil, the cone is used to fix the support in place to prevent settlement. On hard rock surfaces, the plate is used to prevent slipping and displacement. On mountain slopes, the extension length of the plate is adjusted to match the angle. This solves the problem of poor adaptability of traditional single support structures for marker poles, ensuring the stability of the pole in complex terrain and guaranteeing positioning accuracy. 2. The adjustment device adopts a circumferentially distributed threaded shaft and adjustment bushing, combined with the spherical structure of the universal joint shaft, which can finely adjust the pole posture from 360° without relying on external calibration tools; combined with the real-time feedback data from the tilt sensor inside the main pole, a single person can complete the precise calibration, avoiding the shortcomings of traditional benchmarks that rely on multiple devices, have rough calibration and are time-consuming, greatly shortening the benchmark deployment time and improving the efficiency of surveying operations; 3. The modular pole assembly allows for quick assembly and disassembly via threads, and the length can be flexibly spliced ​​according to needs. When fully disassembled, it is easy to carry in complex environments such as mountains and jungles. At the same time, the positioning module and tilt sensor transmit data to the handheld terminal in real time via a wireless module, automatically associating the coordinates of the measuring points with the tilt status. This avoids the problems of omissions and errors that are easy to occur when recording manually, realizing the integration of data acquisition, recording and storage, reducing the workload of surveyors, and improving data reliability and subsequent processing efficiency.

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting the present application. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0021] In the description of this invention, unless otherwise explicitly specified and limited, the term "connection" or similar designation indicating a connection between components should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0022] Example 1: like Figure 1-6 As shown, the present invention provides a portable surveying pole for geological exploration, comprising a modular pole assembly 1, an adjustment device 2 threadedly connected to the lower side of the modular pole assembly 1, a support device threadedly connected to the lower side of the adjustment device 2, the support device including a connecting component 3 threadedly connected to the adjustment device 2, a triangular component 4 provided on the lower side of the connecting component 3, the adjustment device 2 including a universal connecting shaft 22 threadedly connected to the modular pole assembly 1, a fixing block 25 provided on the lower side of the universal connecting shaft 22, a retaining ring 26 provided on the lower side of the fixing block 25, the retaining ring 26 being located inside the fixing cylinder 21, a plurality of threaded shafts 23 provided on the upper side of the fixing cylinder 21, an adjusting bushing 24 provided on the threaded shafts 23, and a movable groove 27 provided on the upper side of the fixing cylinder 21.

[0023] The modular rod assembly 1 includes a main rod 11 connected to a universal joint shaft 22. A first auxiliary rod 12 is threadedly connected to the upper side of the main rod 11. A second auxiliary rod 13 is threadedly connected to the first auxiliary rod 12. A rod end cap 14 is provided on the second auxiliary rod 13. An installation plate 16 is provided on the inner wall of the main rod 11. A positioning module 15 is provided on the upper side of the installation plate 16, and an angle sensor 17 is provided on the lower side.

[0024] Specifically, the main pole is connected to the first and second auxiliary poles by threads, and different lengths can be spliced ​​as needed to adapt to short, medium and long distance survey scenarios. The pole end cap serves as a dustproof seal. The mounting plate on the inner wall of the main pole provides a stable mounting base for the positioning module and the tilt sensor. The positioning module is responsible for collecting the coordinates of the measuring points, and the tilt sensor monitors the tilt state of the pole in real time. The two work together to achieve synchronous monitoring of positioning and attitude, avoiding the cumbersome additional equipment required for measurement of traditional benchmarks.

[0025] The connecting assembly 3 includes a connecting shaft 31 threadedly connected to the fixed cylinder 21. A main cone 33 is located on the lower side of the connecting shaft 31, and multiple corner mounting blocks 32 are located on the outer side of the main cone 33. Specifically, the upper side of the connecting shaft is threadedly connected to the fixed cylinder, achieving a stable connection between the support device and the adjustment device. The lower side is fixed to the main cone, which provides a mounting carrier for the corner mounting blocks. Multiple corner mounting blocks are distributed along the outer side of the main cone to fix the triangular assembly, forming a symmetrical support structure. This ensures uniform transmission of support force and avoids instability caused by excessive force at a single connection point.

[0026] The triangular assembly 4 includes a hinge plate 41 fixedly connected to the corner mounting block 32. The hinge plate 41 has fixed shafts 42 on both sides, and a sliding plate 43 is slidably connected between the fixed shafts 42. The sliding plate 43 has a corner fixing plate 44. The sliding plate 43 has a cone tip storage groove 48 on one side, a supporting cone tip 46 in the cone tip storage groove 48, a locking shaft 45 on the supporting cone tip 46, and a supporting plate 47 hinged to the lower side of the sliding plate 43.

[0027] Specifically, the hinge plate is fixed to the corner mounting block to provide installation support for the skateboard; the fixed shaft is slidably connected to the skateboard, allowing adjustment of the skateboard's extension length to change the support radius and adapt to the support needs of different terrains; the corner fixing plate enhances the structural strength of the skateboard and prevents it from deforming; the support cone tip can be pulled out from the storage slot to be deeply fixed in soft soil, and after being retracted, the support plate is flipped to be slip-resistant on hard ground; the locking shaft is used to lock the position of the support cone tip to ensure stable support, and the whole system can switch between support for multiple terrains.

[0028] Universal connecting shaft 22 passes through movable groove 27. The bottom of universal connecting shaft 22 is spherical and is adapted to fixed block 25. The upper inner wall of fixed cylinder 21 is adapted to the bottom spherical part of universal connecting shaft 22. Fixed cylinder 21 is connected to retaining ring 26.

[0029] Specifically, the universal connecting shaft passes through the movable groove, and the bottom spherical structure is adapted to the fixed block and the upper inner wall of the fixed cylinder to form a universal adjustment structure, which can realize 360° fine adjustment of the rod. The retaining ring is connected to the fixed cylinder, which plays a limiting role in the fixed block, preventing the fixed block from falling off and ensuring the stability of the universal adjustment structure. Through this design, in conjunction with the adjusting bushing, the verticality of the rod can be accurately calibrated.

[0030] The positioning module 15 and the tilt sensor 17 are connected to the handheld terminal via a wireless module. Specifically, the positioning module and the tilt sensor are connected to the handheld terminal via a wireless module, which can transmit the collected coordinate data and tilt data to the terminal in real time without the need for manual reading and recording.

[0031] The main pole 11 houses a battery, which, along with the positioning module 15, is electrically connected to the tilt sensor 17. The main pole 11, the first auxiliary pole 12, and the second auxiliary pole 13 are coated with a scratch-resistant and wear-resistant layer. Specifically, the battery inside the main pole provides continuous power to the positioning module and the tilt sensor, ensuring the equipment functions normally during outdoor surveys without requiring an external power source, thus improving portability. The scratch-resistant and wear-resistant coating on the outer surfaces of the main and auxiliary poles protects against scratches and impacts during outdoor surveys.

[0032] The fixed shaft 42 has a threaded hole on its side, and a fixing bolt is installed in the threaded hole. Specifically, the threaded hole on the side of the fixed shaft cooperates with the fixing bolt. After the slide plate is adjusted to the appropriate extension length, tightening the fixing bolt can lock the relative position of the slide plate and the fixed shaft, preventing the slide plate from sliding due to force during the support process and ensuring the stability of the support radius.

[0033] A locking shaft 45 passes through the slide plate 43, and the bottom of the locking shaft 45 is connected to the support cone tip 46. The support cone tip 46 is slidably connected to the cone tip storage groove 48. Specifically, the locking shaft passes through the slide plate and is connected to the support cone tip at the bottom. When the support cone tip is pulled out, it can be deeply fixed in soft soil. When it is retracted, it can be switched to a support plate mode. This design realizes flexible storage and fixation of the support cone tip, avoiding the problem of the cone tip being exposed and easily damaged or scratched, while ensuring quick switching of the support structure under different terrains.

[0034] The triangular component 4 has three sets corresponding to the corner mounting block 32. The three sets of triangular components 4 are evenly distributed circumferentially, and the threaded shaft 23 is evenly distributed circumferentially along the fixed cylinder 21. Specifically, the three sets of triangular components are evenly distributed circumferentially along the corner mounting block to form a symmetrical support structure, ensuring uniform transmission of support force and preventing the rod from tilting due to uneven force. The multiple sets of threaded shafts are evenly distributed circumferentially along the fixed cylinder. Rotating the corresponding adjusting bushing can push the universal connecting shaft for fine adjustment from different directions, achieving precise calibration of the rod's verticality.

[0035] Usage: Select the splicing length of module pole assembly 1 according to the needs of the exploration scenario: for short-distance operations such as dense jungle areas, use only the main pole 11; for medium-distance operations such as plain exploration, splice the main pole 11 and the first auxiliary pole 12; for long-distance operations such as open mining areas, add the second auxiliary pole 13, and finally install the pole end cap 14 for sealing. Tighten the threaded connection shaft 22 of the universal joint of the adjusting device 2 to the lower side of the main pole 11, and fix the fixed cylinder 21 of the adjusting device 2 to the connecting shaft 31 of the support device with threads to complete the overall assembly.

[0036] Switch the support mode according to the terrain. For soft soil, rotate the locking shaft 45 to pull out the support cone tip 46, loosen the fixing bolt of the fixing shaft 42, slide the slide plate 43 along the fixing shaft to adjust the support radius and increase the support stability, tighten the bolt to lock the slide plate 43, and insert the support cone tip 46 into the soil. For hard rock or hardened ground, retract the support cone tip 46 to the storage groove 48 and rotate the locking shaft 45 to fix it. Flip the support plate 47 to make it fit the ground and use the plate support to prevent slippage. For mountainous slope terrain, adjust the extension length of the 3 sets of slide plates to adapt the support cone tip 46 or the plate to the slope angle to ensure the stability of the pole.

[0037] Open the accompanying APP on the handheld terminal, connect to the wireless signal of the intelligent monitoring unit, and view the tilt data of the tilt sensor 17 in real time. If the rod is tilted, rotate the adjustment sleeve 24 in the corresponding direction of the adjustment device 2: the adjustment sleeve 24 on the tilt side screws in and pushes the ball of the universal joint shaft 22 to move in the opposite direction until the tilt angle data shows that the vertical tilt angle is ≤0.5° to complete the calibration.

[0038] After calibration, the positioning module 15 automatically collects the coordinates of the measuring points and transmits them synchronously with the tilt data to the handheld terminal. The APP automatically records and associates the data. After the operation, disassemble the components: unscrew the support device 3 and the adjustment device 2, retract the slide plate 43, retract the support cone tip 46, flip the support plate 47, disassemble the sections of the module rod assembly 1, and put all parts into the matching portable storage bag with built-in cushioning cotton to prevent collision damage. Charge the battery in the main rod 11, regularly check the wear of each threaded connection, and replace the parts in time if the threads are stripped. Clean the dirt from the support cone tip 46 and the support plate 47 to avoid affecting the next use. Every 3 months, perform accuracy calibration on the positioning module 15 and the tilt sensor 17 using standard calibration equipment to ensure data reliability for the next use.
