Description

Technical Field

[0001] This utility model relates to the technical field of mining area topographic surveying equipment, and in particular to a portable scanner for mining area topographic surveying. Background Technology

[0002] In the field of mining area topographic surveying, 3D laser scanners are commonly used portable surveying equipment. Traditionally, these devices rely on manual handheld operation, requiring surveyors to move around the field to collect topographic data. This method is not only labor-intensive and inefficient, but also poses a risk to the personal safety of surveyors when working in complex terrain or dangerous mining areas.

[0003] With the maturity of drone technology, using drones equipped with 3D laser scanners for mining area topographic surveying has become a new trend. This solution significantly reduces labor intensity and improves inspection efficiency and operational safety. However, existing handheld 3D laser scanners face two major technical challenges when adapted to drone applications: First, due to the lack of a dedicated adapter and fixing mechanism, it is difficult to accurately match the center of gravity when the scanner is installed on the drone, resulting in a significant amount of time spent on debugging and calibration before each takeoff. Second, after the scanner is installed, it is within the coverage area of ​​the drone's shape. During the scanning operation, the laser beam will inevitably scan the drone's own structure, generating a large amount of invalid data, which seriously interferes with the accuracy of the topographic survey results and greatly increases the complexity and workload of subsequent data processing. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a portable scanner for mining area topographic surveying. This utility model has a reasonable structure, with a vertical section fixed base and a horizontal section fixed base working together to accurately fix the drone's legs. The first slide base moves the 3D laser scanner out of the drone's external shape range, avoiding the drone's body structure and reducing invalid scanning data. The second slide base drives the counterweight block to move, achieving center of gravity calibration and shortening debugging time. The adjustment handle is linked to the drive mechanism, which can simultaneously control the fixed base and the slide base, achieving "one-click" installation and calibration. The protective bracket reduces errors and protects the equipment. The integrated design makes it easy to carry. Drone mounting reduces manual labor intensity and safety risks, and improves measurement efficiency and data quality.

[0006] To achieve the above objectives, this utility model proposes a portable scanner for mining area topographic surveying, comprising:

[0011] Drive mechanism: Located inside the housing, driven by an adjustment handle rotatably connected to the surface of the housing. The drive mechanism is connected to the vertical section fixed seat, the horizontal section fixed seat, the first slide, and the second slide.

[0012] In addition, the portable scanner for mining area topographic surveying proposed above may also have the following additional technical features:

[0013] Specifically, the surface of the vertical section fixing seat is provided with an arc-shaped vertical groove that matches the outer dimensions of the vertical section of the UAV leg.

[0014] Specifically, the surface of the horizontal section fixing seat is provided with an arc-shaped flat groove that matches the outer dimensions of the horizontal section of the UAV leg, and an extension is integrally formed at the upper end of the outer port of the arc-shaped flat groove.

[0015] Specifically, the counterweight is cylindrical and is uniformly threaded into the threaded groove on the outer surface of the second slide.

[0016] Specifically, a protective bracket is snapped and fixed at the outer port of the placement cavity. The surface of the protective bracket corresponding to the position of the 3D laser scanner is provided with a protective groove that matches the outer dimensions of the 3D laser scanner. The 3D laser scanner is located in the protective groove.

[0017] Specifically, the driving mechanism includes a bidirectional reciprocating lead screw, a driving main rod, and a first reciprocating lead screw. The bidirectional reciprocating lead screw is rotatably connected to the inner wall of the housing and fixedly connected to one end of the adjusting handle. One end of the first slide and the second slide respectively penetrates into the housing and is threadedly connected to the outer surface of the bidirectional reciprocating lead screw. The driving main rod is rotatably connected to the inner wall of the housing and located on one side of the top of the bidirectional reciprocating lead screw. A first transmission gear and a second transmission gear are respectively provided on the surface of the driving main rod and at corresponding positions on the surface of the bidirectional reciprocating lead screw. The first transmission gear and the second transmission gear mesh with each other. A worm gear portion is uniformly and integrally formed on the surface of the driving main rod, and the top side of the worm gear portion is rotatably connected to... There is a second reciprocating lead screw, which corresponds to the horizontal section fixing seat in the two sets of fixing slots. One end of the second reciprocating lead screw passes through the inside of the fixing slot and is threaded to the inner wall of the horizontal section fixing seat. A worm gear is fixedly connected to the center of the surface of the second reciprocating lead screw and is located inside the housing. The worm gear meshes with the worm. The first reciprocating lead screw is symmetrically rotatably connected to the inner wall of the housing and is located outside the drive rod. One end of each vertical section fixing seat passes through the inside of the housing and is threaded to the outer surface of the first reciprocating lead screw. A central gear and a side gear are respectively provided on the surface of the drive rod and the surface of the first reciprocating lead screw, and the central gear and the side gear mesh with each other.

[0018] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] I. Improve the stability of drones

[0021] (1) Precisely fix the UAV legs: The arc-shaped vertical groove on the surface of the vertical section fixing seat and the arc-shaped flat groove + extension of the horizontal section fixing seat are precisely adapted to the shape of the UAV legs. Through the dual mechanism of shape limit and vertical constraint, the connection between the UAV and the scanner is ensured to be stable, avoiding measurement errors caused by shaking during flight.

[0022] (2) Dynamic balance adjustment of center of gravity: The number of columnar counterweights on the second slide can be flexibly increased or decreased through threaded connection. Combined with the three-dimensional laser scanner on the first slide, the overall center of gravity can be accurately calibrated, solving the problem of time-consuming take-off and debugging caused by center of gravity shift when traditional UAVs are mounted, and shortening the preparation time for operation.

[0023] II. Optimizing Measurement Data Quality and Efficiency

[0024] (1) Avoid interference from UAV structure: The scanner is installed in the housing cavity through the first slide. The first slide can flexibly move the 3D laser scanner to outside the coverage area of ​​the UAV, effectively avoiding interference from the UAV structure, significantly reducing the collection of invalid scanning data, and greatly reducing the complexity and workload of subsequent data processing.

[0025] (2) Integrated control of drive mechanism: By rotating the adjustment handle, the position adjustment of the fixed seat and the slide can be controlled synchronously through the transmission components such as the bidirectional reciprocating screw, the drive main rod, and the reciprocating screw, realizing "one-click" installation and center of gravity calibration. The operation is simple and efficient, and the work efficiency is greatly improved compared with the traditional manual adjustment.

[0026] III. Enhance the portability and protective performance of the equipment.

[0027] (1) Integrated portable design: The fixed groove and handle groove on the top of the box are combined to facilitate hand-carrying or quick assembly with drones. The placement cavity can store the scanner and counterweight to form an integrated portable unit, which can meet the transportation needs of complex terrain in mining areas. The protective card is attached to the outer port of the placement cavity to protect the scanner from collisions and dust, and extend the service life of the equipment.

[0028] (2) Reduce manual labor intensity and safety risks: By using drones to replace manual hand-held scanning, surveyors are prevented from entering dangerous mining areas (such as steep slopes and gas areas), thus ensuring personal safety; at the same time, the amount of on-site mobile work is reduced, reducing labor intensity, which is especially suitable for rapid surveying of large-area mining terrain;

[0029] IV. Technological innovation solves industry pain points

[0030] Addressing the issues of "high labor intensity and low efficiency" in traditional handheld scanning and "difficult center of gravity adjustment and numerous data interferences" in drone-mounted systems, this invention achieves "ready to use" through mechanical structural innovation, eliminating the need for complex calibration procedures. This promotes the automation and intelligent upgrading of mining area topographic surveying and has significant engineering application value. Attached Figure Description

[0041] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0042] The following description, in conjunction with the accompanying drawings, describes a portable scanner for surveying topography in mining areas, according to an embodiment of the present invention.

[0043] like Figures 1-4 As shown in the figure, a portable scanner for mining area topographic surveying according to an embodiment of the present invention includes:

[0044] Box 1: The top is symmetrically provided with fixing grooves 11, and the inside of the fixing grooves 11 is provided with handle grooves 12;

[0045] Vertical section fixing seat 2: symmetrically and in opposite directions slidingly connected to the inner wall of fixing groove 11;

[0046] Horizontal section fixing seat 3: It is evenly and horizontally slidably connected to the inner wall of the fixing groove 11 near the handle groove 12;

[0047] First slide 4 and second slide 5: are horizontally slidably connected to the inner wall of the placement cavity 10 of the box 1, and are arranged in opposite directions. The outer surfaces of the first slide 4 and the second slide 5 are respectively provided with a three-dimensional laser scanner 6 and a counterweight 7.

[0048] Drive mechanism 8: It is located inside the housing 1 and is driven by the adjustment handle 9 which is rotatably connected to the surface of the housing 1. The drive mechanism 8 is connected to the vertical section fixed seat 2, the horizontal section fixed seat 3, the first slide 4 and the second slide 5 respectively.

[0049] It should be noted that the housing 1 has symmetrically opened connection holes 1000, and the inner wall of the connection hole 1000 is threaded with a connection lug.

[0050] Specifically, this utility model has a reasonable structure. Through the coordinated operation of the vertical section fixing seat 2 and the horizontal section fixing seat 3, it achieves precise positioning and stable clamping of the UAV legs. The first sliding seat 4 can flexibly move the 3D laser scanner 6 to outside the coverage area of ​​the UAV's shape, effectively avoiding interference from the fuselage structure, significantly reducing the collection of invalid scanning data, and greatly reducing the complexity and workload of subsequent data processing. The second sliding seat 5 can achieve dynamic calibration of the overall center of gravity by precisely driving the displacement of the counterweight 7, completely solving the problem of takeoff and debugging time caused by center of gravity shift when mounting traditional UAVs, and greatly shortening the operation preparation time. The design of the linkage drive mechanism 8 with the adjustment handle 9 can simultaneously control the position adjustment of the fixed seat and the slide, easily achieving "one-click" installation and center of gravity calibration. The operation process is simplified and efficient. Compared with the traditional manual debugging mode, the work efficiency is significantly improved. The setting of the protective card holder 101 not only reduces installation errors, but also provides reliable protection for core equipment. Its integrated and compact design is easy to carry and transport. Combined with the drone-mounted mode, it can significantly reduce the intensity of manual operation and safety risks, and comprehensively overcome the industry pain points of high labor intensity and complex drone-mounted debugging in traditional measurement operations, fundamentally improving measurement efficiency and data acquisition quality.

[0051] In one embodiment of this utility model, such as Figure 1 As shown, the surface of the vertical section fixing seat 2 is provided with an arc-shaped vertical groove 21 that is adapted to the outer dimensions of the vertical section of the UAV leg.

[0052] Specifically, the surface of the vertical section fixing seat 2 is provided with an arc-shaped vertical groove 21, the outline and size of which are precisely matched with the shape of the vertical section of the drone leg. The arc-shaped vertical groove 21 forms a limiting constraint on the vertical section of the drone leg through a precise shape adaptation design, so as to achieve stable fixation. The close fit between the two effectively enhances the connection stability and provides reliable support for the drone to carry the scanner for operation.

[0053] In one embodiment of this utility model, such as Figure 4As shown, the surface of the horizontal section fixing base 3 is provided with an arc-shaped flat groove 31 that is adapted to the outer dimensions of the horizontal section of the UAV leg, and an extension 32 is integrally formed at the upper end of the outer port of the arc-shaped flat groove 31.

[0054] Specifically, the surface of the horizontal section fixing seat 3 is provided with an arc-shaped flat groove 31. Its outline and size are precisely designed according to the shape parameters of the horizontal section of the UAV outrigger, forming a tightly fitting limiting structure. The extension 32 integrally formed at the upper end of the outer port of the arc-shaped flat groove 31 together with the arc-shaped flat groove 31 constitutes a double fixing mechanism: the arc-shaped flat groove 31 achieves initial limiting through shape adaptation, while the extension 32 forms a constraint barrier in the vertical direction, effectively preventing the horizontal section of the outrigger from vertically displacing in the fixing groove 11, significantly improving connection reliability and operational safety.

[0055] In one embodiment of this utility model, such as Figure 3 As shown, the counterweight 7 is cylindrical and is uniformly threaded into the threaded groove on the outer surface of the second slide block 5.

[0056] Specifically, the counterweight 7 has a columnar structure with threads on its outer surface. The outer surface of the second slide 5 has a corresponding threaded groove. The counterweight 7 is evenly installed in the threaded groove through threaded engagement, achieving a stable connection with the second slide 5. During use, the number of counterweights 7 can be adjusted according to actual needs to balance the overall center of gravity.

[0057] In one embodiment of this utility model, such as Figures 1-2 As shown, protective brackets 101 are snapped and fixed at the outer port of the placement cavity 10. The protective brackets 101 corresponding to the position of the 3D laser scanner 6 have protective grooves on their surfaces that are adapted to the external dimensions of the 3D laser scanner 6. The 3D laser scanner 6 is located in the protective grooves.

[0058] Specifically, a protective bracket 101 is snapped and fixed to the outer port of the placement cavity 10. The surface of the bracket corresponding to the 3D laser scanner 6 is provided with a protective groove that fits precisely. After the scanner is fitted, it can resist collisions and isolate dust through the rounded chamfer of the groove edge and the shock-absorbing silicone layer on the inner wall, which significantly improves the measurement stability and service life in complex industrial environments. At the same time, the embedded design makes the outer surface of the device flush and reduces spatial interference.

[0059] In one embodiment of this utility model, such as Figure 3As shown, the drive mechanism 8 includes a bidirectional reciprocating lead screw 81, a drive main rod 82, and a first reciprocating lead screw 83. The bidirectional reciprocating lead screw 81 is rotatably connected to the inner wall of the housing 1 and fixedly connected to one end of the adjusting handle 9. One end of the first slide 4 and the second slide 5 respectively penetrates into the interior of the housing 1 and is threaded to the outer surface of the bidirectional reciprocating lead screw 81. The drive main rod 82 is rotatably connected to the inner wall of the housing 1 and is located on one side of the top of the bidirectional reciprocating lead screw 81. A first transmission gear 100 and a second transmission gear 200 are respectively provided on the surface of the drive main rod 82 at positions corresponding to the surface of the bidirectional reciprocating lead screw 81. The first transmission gear 100 and the second transmission gear 200 mesh with each other. A worm gear portion 300 is uniformly and integrally formed on the surface of the drive main rod 82. A second reciprocating lead screw 83 is rotatably connected to one side of the top of the worm gear portion 300. The second reciprocating screw 400 corresponds to the horizontal section fixing seat 3 in the two sets of fixing slots 11. One end of the second reciprocating screw 400 passes through the inside of the fixing slot 11 and is threaded to the inner wall of the horizontal section fixing seat 3. A worm gear 500 is fixedly connected to the center of the surface of the second reciprocating screw 400 and is located inside the housing 1. The worm gear 500 meshes with the worm part 300. The first reciprocating screw 83 is symmetrically rotated and connected to the inner wall of the housing 1 and is located outside the drive main rod 82. One end of the vertical section fixing seat 2 passes through the inside of the housing 1 and is threaded to the outer surface of the first reciprocating screw 83. A middle gear 600 and a side gear 700 are respectively provided on the surface of the drive main rod 82 and the surface of the first reciprocating screw 83, and the middle gear 600 and the side gear 700 mesh with each other.

[0060] Specifically, the working principle of the drive mechanism 8 is as follows: rotating the adjustment handle 9 drives the bidirectional reciprocating screw 81, which is fixedly connected to it, to rotate synchronously. Since one end of the first slide 4 and the second slide 5 passes through the inside of the housing 1 and is threadedly connected to the outer surface of the bidirectional reciprocating screw 81, the rotation of the bidirectional reciprocating screw 81 causes the first slide 4 and the second slide 5 to slide horizontally in opposite directions on the inner wall of the placement cavity 10 of the housing 1, thereby realizing the position adjustment of the three-dimensional laser scanner 6 and the counterweight 7.

[0061] When the bidirectional reciprocating screw 81 rotates, the second transmission gear 200 on its surface meshes with the first transmission gear 100 on the surface of the drive main rod 82, transmitting power to the drive main rod 82 and causing it to rotate synchronously. The worm gear 300 evenly distributed on the surface of the drive main rod 82 rotates accordingly. The worm gear 300 meshes with the worm wheel 500 on the surface of the second reciprocating screw 400, causing the second reciprocating screw 400 to rotate. Since one end of the second reciprocating screw 400 penetrates into the fixed groove 11 and is threaded to the inner wall of the horizontal section fixed seat 3, the rotation of the second reciprocating screw 400 causes the horizontal section fixed seat 3 to slide horizontally on the inner wall of the fixed groove 11 near the handle groove 12, thus completing the adjustment of the horizontal section fixed position of the UAV legs.

[0062] At the same time, when the main drive rod 82 rotates, the central gear 600 on its surface meshes with the side gear 700 on the surface of the first reciprocating screw 83, transmitting power to the first reciprocating screw 83. Since one end of the vertical section fixing seat 2 penetrates into the housing 1 and is threaded to the outer surface of the first reciprocating screw 83, the rotation of the first reciprocating screw 83 causes the vertical section fixing seat 2 to slide symmetrically in opposite directions on the inner wall of the fixing groove 11, thereby adjusting the vertical fixed position of the UAV legs.

[0063] Through the above transmission process, rotating the adjustment handle 9 can realize the synchronous driving and position adjustment of the vertical section fixed seat 2, the horizontal section fixed seat 3, the first slide 4 and the second slide 5 by the drive mechanism 8. The operation is simple and the effect is good.

[0064] In summary, this utility model provides a portable scanner for mining area topographic surveying. The structure is reasonable, with the vertical section fixing seat 2 and the horizontal section fixing seat 3 working together to precisely fix the drone's legs. The first sliding seat 4 moves the 3D laser scanner 6 out of the drone's outline, avoiding the drone's structure and reducing invalid scanning data. The second sliding seat 5 drives the counterweight block 7 to shift, achieving center of gravity calibration and shortening debugging time. The adjustment handle 9, linked to the drive mechanism 8, can simultaneously control the fixing seat and sliding seat, achieving "one-click" installation and calibration. The protective bracket 101 reduces errors and protects the equipment. The integrated design facilitates portability. Drone mounting reduces manual labor and safety risks, improving measurement efficiency and data quality.
