Description

Technical Field

[0001] This invention relates to the field of engineering surveying technology, and more specifically to an engineering surveying device based on natural resources. Background Technology

[0002] In the fields of field engineering surveying, such as natural resource investigation and monitoring, land surveying, geological exploration, and water conservancy and mining engineering, devices that measure linear dimensions such as length, distance, area, and angle using optical methods, such as handheld laser rangefinders, portable total stations, and field 3D scanners, are core tools for acquiring spatial geometric information of natural features. These devices emit a measurement beam through an objective lens, which, after diffuse reflection from the surface of the natural target, is converged to the detector by a receiving optical system, completing a single distance (length) or angle sampling within seconds. At the moment of measurement, the objective lens or eyepiece, as the only interface between the optical measurement link and the environment, needs to be fully exposed to ensure distortion-free beam emission and full-aperture reception of the echo signal. Natural resource field surveys have typical mobile operational characteristics: natural resource field survey operations possess significant... Due to the mobile nature of field operations, after completing measurements at a single station, operators must immediately remove the instrument from its support or handheld position, store it in a backpack, or carry it by hand to the next measurement point on foot. The reciprocating multi-directional vibrations generated during the foot transfer cause the instrument to undergo gradual micro-creep and attitude settlement within the flexible liner. This results in differences in the instrument's actual spatial orientation within the liner each time it is unpacked. To suppress this orientation shift, the existing liner structure requires applying a high clamping force to the instrument. However, excessive clamping force further exacerbates over-positioning stress, subjecting the instrument housing and internal precision displacement mechanisms to unexpected assembly stresses. This can lead to minute displacements of optical components, ultimately resulting in decreased measurement accuracy, reduced long-term operational stability, and a significant reduction in the overall efficiency of field measurement operations. Summary of the Invention

[0003] The purpose of this invention is to provide an engineering measurement device based on natural resources to address the aforementioned shortcomings in the technology.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an engineering measurement device based on natural resources, comprising an optical measuring instrument, an optical window, and a take-up and drop-down box, wherein the take-up and drop-down box is provided with a fast measurement component, and the fast measurement component is used to enable the optical measuring instrument and the optical window to quickly reset and maintain the working state for measurement after the measurement is transferred to the next measurement point; The rapid testing component includes several limiting frames movably connected inside the optical measuring instrument, and the limiting frames are evenly distributed at the four corners outside the optical measuring instrument. Each limiting frame has a contact rod installed on the side closest to the optical measuring instrument, and the contact rod is slightly tilted relative to the optical measuring instrument. A centering shaft is connected between the contact rod and the limiting frame.

[0005] Preferably, the elastic component includes a centering groove formed on one side of the limiting frame for guiding the movement of the abutment rod and a migration ring installed on the top of the abutment rod, wherein the migration ring is located inside the centering groove, and a return spring is connected between the migration ring and the centering groove.

[0006] Preferably, the rotating assembly includes a servo motor fixedly connected inside the receiving box and a transfer rod fixedly connected to the bottom of the limiting frame.

The inside of the receiving box is fixedly connected to a guide rail seat, and the top of the guide rail seat is used to support the bottom of the rotating disk. The side of the limiting frame near the migration rod is fixedly connected to a slide, and the slide is movably sleeved on the outside of the guide rail seat.

[0007] Preferably, the blowing assembly includes a horizontal cylinder installed inside the take-up and take-down box and a stabilizing frame disposed at one end of the horizontal cylinder near the optical window. An active air ring communicating with the interior of the stabilizing frame is fixedly connected to the end of the stabilizing frame away from the horizontal cylinder. A driven air ring is installed at one end of the horizontal cylinder and is located at the top of the stabilizing frame. A blower is fixedly connected inside the stabilizer frame, and two directional air rings communicating with the inside are fixedly connected to the outside of the stabilizer frame. Flexible hoses are respectively connected between the outside of the two directional air rings and the driven air ring and the blower. The inside of the cross cylinder is equipped with a multi-dimensional component, which is used to drive the stabilizer to rotate while pushing the driven air ring to reciprocate along the top of the stabilizer. The internal structure of the take-up and take-down box is equipped with a bidirectional component, which is used to drive the horizontal cylinder to move in multiple dimensions along one side of the optical window.

[0008] Preferably, the multidimensional component includes a multidimensional column rotatably connected inside the horizontal cylinder and a limiting rod fixedly connected to one end of the stabilizing frame, with one end of the limiting rod extending into the interior of the horizontal cylinder and fixedly connected to the multidimensional column. A power motor is fixedly connected inside the horizontal cylinder, and the output end of the power motor is fixedly connected to one end of the multidimensional column.

[0009] Preferably, a stabilizing rod is fixedly connected to one end of the driven air ring near the cross cylinder, and one end of the stabilizing rod extends into the interior of the cross cylinder. A slip ring is installed on one side of the stabilizing rod inside the cross cylinder. A first sliding groove and a second sliding groove are respectively opened on the outside of the multi-dimensional column for guiding the movement of the slip ring, and the interiors of the first sliding groove and the second sliding groove are connected. The second sliding groove is designed as a curved arc structure.

[0010] Preferably, the bidirectional assembly includes a drive motor fixedly connected inside the take-up and take-down box and an inner liner fixedly connected to one end of the cross cylinder. The output end of the drive motor is fixedly sleeved with a connecting rod, and one end of the connecting rod is movably sleeved outside the inner liner.

[0011] Preferably, a torsion shaft is fixedly connected inside the take-up and take-down box, and the torsion shaft is designed with an L-shaped structure. The torsion shaft and the drive motor are arranged vertically and alternately inside the take-up and take-down box. A torsion slide rod is installed at the end of the inner lining column away from the cross cylinder. A torsion seat is movably connected to one end of the torsion shaft, and the torsion seat is movably sleeved on the outside of the torsion slide rod.

[0012] The technical effects and advantages provided by the present invention in the above technical solution are as follows: 1. By setting up the storage box, limiting frame, and abutment rod, during the lowering and storage of the optical measuring instrument, the wedge-shaped guide structure formed by the inclined support surface of the abutment rod and the side wall of the optical measuring instrument converts the translational kinetic energy of the instrument into a centripetal sliding component. Combined with the mechanical filtering effect of the inclined plane, the large-scale positional deviation of the initial placement can be automatically converged to a precise alignment posture. The four limiting frames and abutment rods form four-point discrete contact constraints at the four corners of the optical measuring instrument, applying the constraint reaction force of external impact to the edge area with the strongest stiffness of the instrument, forming a spatially statically indeterminate clamp and completely restricting the six spatial degrees of freedom of the instrument. During the transfer of measurement points, the tangential decomposition of vertical inertial force is used to achieve a self-tightening effect, avoiding shaking, collision, and positional deviation of the optical measuring instrument when moving to the next detection point. This ensures the safety of the instrument structure and optical components during transportation, and ensures that after the device is transferred to the next measurement point and taken out for use, it can be directly put into the survey operation without recalibrating the reference, effectively improving the overall operational efficiency of the device for natural resource area measurement.

[0013] 2. By setting up the contact rod, centering shaft, return spring, threaded column, and torsion ring, the contact rod forms a lever swing structure with the centering shaft as the fulcrum. The bottom uses rigid contact to form a hard point positioning reference, and the top achieves elastic adaptive contact through the return spring, forming a graded clamping constraint that is flexible at the top and rigid at the bottom. The elastic tension of the return spring can be precisely adjusted through the threaded column and torsion ring, which ensures the reliability of the clamping limit while avoiding excessive clamping. When the instrument falls, the elastic top can bend and retreat in a controlled manner and provide a secondary guiding force, eliminating the assembly stress of optical components caused by forced correction. The positioning state is guaranteed only by low-stress constraints that maintain the attitude, which significantly improves the accuracy and stability of the measurement results of the optical measuring instrument and optical window.

[0014] 3. With the servo motor, rotating disk, and transfer slot, the servo motor drives the rotating disk and transfer slot to rotate. The slot rod abuts against each other, causing the limiting frame to move horizontally along the guide rail. The clamping distance between the limiting frame, the abutting rod, and the outer wall of the optical measuring instrument can be precisely adjusted. It can adapt to the storage and positioning needs of optical measuring instruments of different shapes, sizes, and specifications, thus broadening the applicability of the device. At the same time, the guiding cooperation between the guide rail and the slide ensures that the distance adjustment process is smooth and accurate, avoiding the offset of the clamping center.

[0015] 4. Through the configuration of a blower, directional air ring, stabilizer, active air ring, and driven air ring, the blower generates continuous negative pressure intake and high pressure exhaust through the centrifugal action of the impeller. The airflow is synchronously delivered to the active and driven air rings via the directional air ring and stabilizer, constructing a stable and controllable closed-loop airflow supply system. It can provide sufficient airflow for cleaning optical windows without the need for an external air source. The airflow distribution is uniform and the pressure is stable, providing a reliable power foundation for subsequent window dust removal operations. It is suitable for field land surveying operations without an external air source.

[0016] 5. Through the configuration of the drive motor, connecting rod, inner liner column, torsion slide bar, and torsion seat, the drive motor drives the connecting rod to rotate, causing the inner liner column to complete the attitude conversion from arc motion to horizontal motion, realizing the automatic switching of the horizontal cylinder and air ring assembly from the vertical storage state to the horizontal alignment state; the initial storage posture can avoid the lowering path of the optical measuring instrument, avoiding interference with storage, and the airflow generated during the flipping motion can blow the floating dust in the ring groove away from the optical window, realizing the self-cleaning of the air ring assembly and preventing secondary contamination of the optical window by accumulated dust.

[0017] 6. Through the configuration of a power motor, multi-dimensional column, limiting rod, stabilizing rod, first slide groove, second slide groove, and slip ring, the power motor drives the multi-dimensional column to rotate, causing the stabilizing frame and active air to sweep around the optical window axis in a circumferential direction. At the same time, the cooperation of the slide groove and slip ring drives the driven air ring to feed radially, combining the circumferential rotation and radial feed into a spiral airflow coverage trajectory. This enables thorough cleaning of the entire surface of the optical window without dead angles, solving the problems of incomplete cleaning and blind spots in traditional single-point blowing cleaning, and significantly improving the cleaning coverage and cleaning effect of the optical window.

[0018] 7. By setting up active and passive air rings, the two form a dynamic air guiding mechanism with mutual geometric boundaries in the moving flow field. The active air ring forms an annular windbreak boundary, and the passive air ring constrains the airflow into a directional jet pointing towards the optical window, effectively converging the airflow and enhancing the dynamic pressure retention capability of the window surface. This avoids the rapid attenuation of airflow caused by the open space of the take-up and take-down box, and can achieve efficient removal of floating dust even at low airflow rates. This reduces energy consumption while ensuring cleaning efficiency, so that the optical window is in a clean and ready state when the optical measuring instrument arrives at the next measuring point. It can be taken out and measured directly, which greatly improves the continuity and work efficiency of land surveying field operations. Attached Figure Description

[0022] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0023] This invention provides, for example Figure 1 , Figure 2 and Figure 3 The diagram shows an engineering surveying device based on natural resources, including an optical measuring instrument 1, an optical window 11, and a take-up and drop-down box 12. The take-up and drop-down box 12 is equipped with a quick measurement component 2, which is used to quickly reset the optical measuring instrument 1 and the optical window 11 after the measurement is transferred to the next measurement point and maintain the working state for measurement. The specific structure and principle of the optical measuring instrument 1 are all existing technologies, so they are not described in detail in this application. At present, in the process of natural resource engineering surveying, the conventional surveying operation process of the optical measuring instrument 1 usually includes the following implementation steps: Since the actual measurement site of natural resource engineering is open, the terrain is complex and varied, and there are often irregular boundary contours, the industry generally adopts a multi-point closed polygon fitting algorithm. The operator surrounds the irregular area to be measured and selects multiple contour inflection points as fixed measurement points in sequence. At each calibrated inflection point, the optical measuring instrument 1 equipped with laser ranging function emits a probe laser in the direction of the center diagonal point of the area to be measured and the adjacent contour inflection point. The equipment simultaneously collects and records multi-dimensional survey data such as spatial slant distance, horizontal azimuth angle, and pitch angle in real time. The built-in data processing module of the measuring instrument automatically corrects and converts all the slope distance parameters collected on site into horizontal plane coordinates based on the attitude compensation logic, and converts each field measurement point into a standard plane rectangular coordinate point. The main control chip inside the equipment retrieves the preset polygon closure area calculation formula, and connects all the converted coordinate points one by one according to the layout order of the survey points. The system automatically fits the closed contour based on the arrangement of the closed coordinate points, and performs geometric calculations through plane coordinate integration to directly and accurately calculate the actual horizontal projected area corresponding to the irregular area to be measured. The rapid testing component 2 includes several limiting frames 21 movably connected inside the optical measuring instrument 1, and the several limiting frames 21 are evenly distributed at the four corners outside the optical measuring instrument 1. Each limiting frame 21 has a contact rod 22 installed on the side close to the optical measuring instrument 1, and the contact rod 22 is slightly tilted relative to the optical measuring instrument 1.

The limiting frame 21 is provided with an elastic component 3 on its outside, and the elastic component 3 is used to keep the top of the contact rod 22 in an adaptive state with the outside of the optical measuring instrument 1. The elastic component 3 includes a centering groove 31 opened on one side of the limiting frame 21 for guiding the movement of the contact rod 22 and a migration ring 32 installed on the top of the contact rod 22. The migration ring 32 is located inside the centering groove 31, and the migration ring 32 and the centering groove 31 are connected together by a return spring 33. The external part of the limiting frame 21 is provided with a threaded post 35, and the external part of the limiting frame 21 is provided with a threaded hole 36 that communicates with the interior of the centering groove 31 for the threaded post 35 to be screwed in. The interior of the centering groove 31 is slidably connected with a torsion ring 34, and one end of the torsion ring 34 is fixedly connected to one end of the return spring 33. One end of the threaded column 35 located inside the centering groove 31 is movably connected to one end of the torsion ring 34; The specific number of limiting frames 21 is four, and the four limiting frames 21 are arranged around the inside of the optical measuring instrument 1. At the same time, the four limiting frames 21 surround the four corners of the outside of the optical measuring instrument 1. In addition, the side of the abutment rod 22 near the optical measuring instrument 1 is made of flexible material, which can form flexible protection with the outside of the optical measuring instrument 1. The take-up and take-down box 12 is equipped with a rotation assembly, which is used to adjust the distance between the contact rod 22 and the optical measuring instrument 1. The rotation assembly includes a servo motor 24 fixedly connected inside the take-up and take-down box 12 and a transfer rod 27 fixedly connected to the bottom of the limiting frame 21. The output end of the servo motor 24 is fixedly connected to a rotating disk 25. The top of the rotating disk 25 is provided with a transfer groove 26 for guiding the transfer rod 27 to move. The transfer groove 26 is designed with an arc shape. The inside of the receiving box 12 is fixedly connected to a guide rail seat 28, and the top of the guide rail seat 28 is used to support the bottom of the rotating disk 25. The side of the limiting frame 21 near the transfer rod 27 is fixedly connected to a slide 29, and the slide 29 is movably sleeved on the outside of the guide rail seat 28.

[0024] refer to Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the take-up and take-down box 12 is equipped with a blowing assembly 4, which is used to generate a suspended airflow outside the optical window 11. The blowing assembly 4 includes a horizontal cylinder 42 installed inside the take-up and take-down box 12 and a stabilizing frame 41 located at one end of the horizontal cylinder 42 near the optical window 11. An active air ring 43 communicating with the interior of the stabilizing frame 41 is fixedly connected to the end of the stabilizing frame 41 away from the horizontal cylinder 42. A driven air ring 44 is installed at one end of the horizontal cylinder 42 and is located on top of the stabilizing frame 41. Both the active air ring 43 and the driven air ring 44 are equipped with jet heads on their exteriors, and the jet head outside the active air ring 43 is connected to the stabilizing frame 41. The interior of the mounting rack 41 is interconnected, allowing the airflow inside the mounting rack 41 to be collected and then ejected through the corresponding jet head. Moreover, the two directional air rings 46 provide special guidance for the airflow. One directional air ring 46 delivers the airflow generated by the blower 45 into the interior of the mounting rack 41, while the other directional air ring 46 delivers the airflow inside the mounting rack 41 into the interior of the driven air ring 44, thereby creating a flow rate difference. At the same time, the mounting rack 41 is designed with an I-shaped structure, which allows the connection between it and the active air ring 43 to be in a hollow state, which facilitates the collection and guidance of the airflow. A blower 45 is fixedly connected inside the stabilizer 41, and two directional air rings 46 that communicate with the inside are fixedly connected outside the stabilizer 41. Flexible hoses 47 are respectively connected between the outside of the two directional air rings 46 and the driven air ring 44 and the blower 45. The horizontal cylinder 42 is equipped with a multi-dimensional component 5, which drives the stabilizer 41 to rotate while simultaneously pushing the driven air ring 44 to reciprocate along the top of the stabilizer 41. The multi-dimensional component 5 includes a multi-dimensional column 51 rotatably connected inside the horizontal cylinder 42 and a limiting rod 52 fixedly connected to one end of the stabilizer 41. One end of the limiting rod 52 extends into the interior of the horizontal cylinder 42 and remains fixedly connected to the multi-dimensional column 51. A power motor 57 is fixedly connected inside the horizontal cylinder 42. The output end of 7 is fixedly connected to one end of the multi-dimensional column 51. The driven air ring 44 is also fixedly connected to a stabilizing rod 53 near the end of the horizontal cylinder 42. One end of the stabilizing rod 53 extends into the interior of the horizontal cylinder 42. A slip ring 54 is installed on one side of the stabilizing rod 53 inside the horizontal cylinder 42. The outside of the multi-dimensional column 51 is provided with a first sliding groove 55 and a second sliding groove 56 for guiding the movement of the slip ring 54. The interiors of the first sliding groove 55 and the second sliding groove 56 are connected. The second sliding groove 56 is designed as a curved arc structure. The take-up and take-down box 12 is equipped with a bidirectional component 6, which is used to drive the horizontal cylinder 42 to move in multiple dimensions along one side of the optical window 11. The bidirectional component 6 includes a drive motor 62 fixedly connected inside the take-up and take-down box 12 and an inner liner column 64 fixedly connected to one end of the horizontal cylinder 42. The output end of the drive motor 62 is fixedly sleeved with a connecting rod 63, and one end of the connecting rod 63 is movably sleeved on the outside of the inner liner column 64. Furthermore, there is a movable gap between the drive motor 62 and the bottom of the take-up and take-down box 12, which facilitates the stabilizing frame 41 to rotate and move horizontally along the inside of the take-up and take-down box 12, so as to maintain a suitable gap between the stabilizing frame 41 and the optical window 11. The inside of the take-up and take-down box 12 is fixedly connected to a torsion shaft 67, and the torsion shaft 67 is designed with an L-shaped structure. The torsion shaft 67 and the drive motor 62 are arranged vertically and alternately inside the take-up and take-down box 12. A torsion slide rod 66 is installed at the end of the inner lining column 64 away from the horizontal cylinder 42. A torsion seat 65 is movably connected to one end of the torsion shaft 67, and the torsion seat 65 is movably sleeved on the outside of the torsion slide rod 66.

[0025] Working principle: When using: refer to Figure 1 and Figure 2 As shown, in engineering geometric measurement operations in the field of land surveying and natural resources, when the measurement of the current measuring point is completed and it is necessary to move to the next measuring point; First, after the optical measuring instrument 1 and optical window 11 complete the mapping of the current measurement point, the optical measuring instrument 1 is placed inside the take-up box 12. During the descent of the optical measuring instrument 1, its outer wall first contacts the wide opening area at the top of the limiting frame 21 and the abutment rod 22. Under the action of gravity, the optical measuring instrument 1 continues to sink. The inclined support surface of the abutment rod 22 forms a wedge-shaped gap with the side wall of the optical measuring instrument 1, converting the translational kinetic energy of the optical measuring instrument 1 into a tangential component force that slides down the inclined surface. This forces the optical measuring instrument 1 to automatically retract and align with the center of the take-up box 12 during the descent. During this process, the inclined guide surfaces of the limiting frame 21 and the abutment rod 22 form a mechanical filtering effect, gradually converging the large-scale pose deviation at the initial placement to the precise alignment posture in the narrow opening area at the bottom. The four limiting frames 21 The four corner positions of the contact rod 22 are respectively arranged at the four corner positions outside the optical measuring instrument 1 to form a four-point discrete contact constraint. The edge extreme point of the optical measuring instrument 1 is fixedly constrained, so that when the external impact is transmitted to the optical measuring instrument 1, the constraint reaction force acts on the edge area with the strongest structural stiffness of the optical measuring instrument 1. The force flow transmission path is direct and closed. The four corner constraints form a statically indeterminate clamping structure in space, which completely restricts all six spatial degrees of freedom of the optical measuring instrument 1 inside the take-up and put-down box 12. During the process of the optical measuring instrument 1 and the take-up and put-down box 12 being transferred to the next measurement point, there is a normal angle between the inclined surface of the contact rod 22 and the vertical direction. The vertical inertial force is decomposed into a tangential component along the inclined surface. This component pushes the optical measuring instrument 1 continuously towards the bottom of the four corner constraints, forming a stable self-tightening clamping effect. refer to Figure 1 , Figure 2 and Figure 3As shown, when the optical measuring instrument 1 moves downward along the inclined surface of the contact rod 22, the outer wall of the contact rod 22 abuts against the outer wall of the optical measuring instrument 1 and generates a reaction force, causing the contact rod 22 to oscillate slightly along the centering groove 31 and the limiting frame 21 after being subjected to force. The bottom of the contact rod 22 slowly moves towards the inside of the centering groove 31, and the top of the contact rod 22 slowly approaches the top of the optical measuring instrument 1. The two ends of the contact rod 22 use the centering shaft 23 as a fulcrum and make lever movements along the outer wall of the optical measuring instrument 1. One side of the contact rod 22 adopts a flexible structure, which can effectively absorb the squeezing force generated by deformation, so that the bottom of the contact rod 22 is stably attached to the outer wall of the optical measuring instrument 1. During the contact process between the top of the contact rod 22 and the top of the optical measuring instrument 1, the return spring 33 moves towards the migration ring 32 by its own elastic deformation. A thrust is applied from one side, pushing the migration ring 32 and the contact rod 22 closer to the top of the optical measuring instrument 1. At the same time, the threaded column 35 is rotated to maintain a helical engagement with the threaded hole 36. The threaded column 35 extends into or slides out of the centering groove 31 along the threaded hole 36. When the threaded column 35 moves along the centering groove 31, it pushes the torsion ring 34 to move left and right along the centering groove 31. The displacement of the torsion ring 34 can adjust the elastic tension of the return spring 33, so that the top of the contact rod 22 and the top of the optical measuring instrument 1 maintain an elastic adaptive fit, which not only achieves reliable positioning but also avoids excessive clamping. Furthermore, the bottom of the contact rod 22 and the optical measuring instrument 1 are rigidly connected to form a hard point positioning reference. The elastic adaptive contact area at the top of the contact rod 22 conforms to the outline of the outer shell of the optical measuring instrument 1 with the flexible characteristics of reversible deformation. refer to Figure 1 , Figure 2 and Figure 3 As shown, during the descent of the optical measuring instrument 1, its sidewalls interfere with the elastic top of the contact rod 22. The elastic top undergoes controlled deflection and lateral retraction, while simultaneously providing a secondary guiding force to press the optical measuring instrument 1 towards the stable contact side, achieving precise positioning constraint and forming a graded clamping force that is flexible at the top and rigid at the bottom. This constraint method can prevent the optical measuring instrument 1 from being forcibly corrected during placement, and avoids the introduction of assembly stress inside the optical components due to the locking force forcibly straightening the misaligned optical measuring instrument 1. The sequential constraint ensures that the final stress is only used to maintain a stable posture, rather than to correct the posture, effectively improving the accuracy of the measurement results of the optical measuring instrument 1 and the optical window 11. Secondly, when it is necessary to adjust the clamping distance between the contact rod 22 and the outer wall of the optical measuring instrument 1, the servo motor 24 starts and drives the rotating disk 25 to rotate synchronously, and the migration groove 26 rotates synchronously with the rotating disk 25; the inner wall of the migration groove 26 abuts against the outer wall of the migration rod 27, pushing the migration rod 27 to move horizontally in a straight line, and the displacement of the migration rod 27 drives the limiting frame 21 to move horizontally synchronously, and the slide 29 slides horizontally along the outer wall of the guide rail seat 28 with the displacement of the limiting frame 21, thereby accurately adjusting the clamping distance between the limiting frame 21 and the optical measuring instrument 1; refer to Figure 4 and Figure 5 As shown, finally, when the optical measuring instrument 1 and the optical window 11 are stably limited inside the receiving box 12 by the limiting frame 21 and the abutment rod 22, in the initial state, the stabilizing frame 41 and the driven air ring 44 are close to the inner wall of the receiving box 12, and a gap is maintained between them to avoid the lowering path of the optical measuring instrument 1 and the optical window 11. Then, the blower 45 starts to drive, and its internal impeller rotates at high speed. The blades rotate at high speed synchronously with the impeller, causing the air in the cavity to rotate synchronously. The air molecules are subjected to strong centrifugal force and are quickly thrown radially from the center of the impeller to the outer edge of the impeller. After the air inside the impeller is continuously thrown to the outside, the air density at the impeller axis position decreases. The air pressure decreases, forming a local negative pressure low-pressure area. Under the action of atmospheric pressure, external air is continuously forced in from the air inlet of the blower 45 to replenish the negative pressure area at the center of the impeller, achieving continuous air intake, converting the kinetic energy of the air into the potential energy of the wind pressure, and guiding it uniformly to the air outlet; the airflow is transported to the inside of the stabilizer 41 through one of the directional air rings 46, and the stabilizer 41 guides the collected airflow to the active air ring 43, so that a directional airflow is formed around the active air ring 43; at the same time, the airflow inside the stabilizer 41 is transported to the inside of the other directional air ring 46, and the other directional air ring 46 transports the airflow to the inside of the driven air ring 44, so that a directional airflow is synchronously formed around the driven air ring 44; refer to Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the drive motor 62 starts driving, and its output end drives the connecting rod 63 to rotate synchronously. When the connecting rod 63 rotates, its inner wall abuts against the outer wall of the inner lining column 64, pushing the inner lining column 64 to move upward. The movement path of the inner lining column 64 changes synchronously with the rotation direction of the connecting rod 63. At the same time, the movement path of the inner lining column 64 is restricted after displacement. The inner lining column 64 rotates along the inside of the connecting rod 63, and drives the torsion slide rod 66 and the torsion seat 65 to rotate along the outer wall of the torsion shaft column 67, releasing the path restriction of the inner lining column 64, so that the movement form of the inner lining column 64 changes from arc motion to horizontal linear motion. The connecting rod 63 continues to rotate, and its inner wall pulls the inner lining column 64 to move horizontally. The displacement of the inner lining column 64 drives the torsion slide rod 66 to slide along the guide inside the torsion seat 65, thereby changing the horizontal cylinder 42 from a vertical state to a horizontal state. The horizontal cylinder 42 moves towards the outer wall of the optical window 11 under the drive of the inner lining column 64. As the device slowly approaches, during the entire movement of the horizontal cylinder 42, the airflow generation structures of the driven air ring 44 and the active air ring 43 generate the first airflow as they rotate. The direction of the airflow changes dynamically with the rotation angle. In the initial stage of rotation, the airflow blows the floating dust accumulated in the ring's recess towards the area away from the optical window 11, achieving self-cleaning of the component. In the final stage of rotation and horizontal movement, the airflow initially acts on the surface of the optical window 11, loosening the dust particles with weak adsorption. After the first movement state is completed, the driven air ring 44 and the active air ring 43 are in a position close to the optical window 11, and then enter the second movement state. The power motor 57 starts to drive the multi-dimensional column 51 to rotate along the inside of the horizontal cylinder 42. The rotation of the multi-dimensional column 51 drives the limiting rod 52 to rotate synchronously. The rotation of the limiting rod 52 drives the stabilizing frame 41 to rotate, thereby driving the entire airflow action surface to sweep around the axis of the optical window 11 in a circumferential manner. refer to Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, simultaneously, the rotation of the multidimensional column 51 synchronously drives the first slide groove 55 to rotate. The inner wall of the first slide groove 55 slides along the outer wall of the slip ring 54, and the slip ring 54 approaches the junction of the first slide groove 55 and the second slide groove 56. This process causes the driven air ring 44 to briefly stop along the outer wall of the stabilizer 41. After the slip ring 54 moves to the junction of the first slide groove 55 and the second slide groove 56, it slides into the interior of the second slide groove 56. When the second slide groove 56 rotates, its inner wall and the outer wall of the slip ring 54 abut against each other and push the slip ring 54 to move horizontally in a straight line. The displacement of the slip ring 54 pushes the stabilizing rod 53 to move horizontally along the interior of the cross cylinder 42, thereby causing the driven air ring 44 to move horizontally along the outer wall of the stabilizer 41, changing its outlet position and the radial feed amount along the optical window 11. The circumferential rotation and the radial feed combine to form a spiral airflow covering trajectory. The rotation of the active air ring 43 realizes the full traversal of the angle of the mapping window, and the radial displacement of the driven air ring 44 adjusts the radius of the airflow. The active air ring 43, when rotating, forms a moving annular windbreak boundary as its ring shape rotates. The driven air ring 44, located at its top forward position, is constrained by the inner wall of the active air ring 43, forming a directional jet pointing towards the optical window 11. At the same time, the driven air ring 44 changes the flow field boundary after the active air ring 43's own airflow exits, concentrating the originally diffused airflow within a local area of ​​the optical window 11. The driven air ring 44 and the active air ring 43 form a dynamic air guiding mechanism with mutual geometric boundaries in the moving flow field, significantly enhancing the dynamic pressure retention capability of the airflow on the surface of the optical window 11, avoiding rapid airflow attenuation due to the open space inside the take-up and drop-down box 12, and achieving efficient removal of floating dust at low flow rates. When the operator arrives at the next measurement point and opens the take-up and drop-down box 12, the optical window 11 is already in a clean and unobstructed ready state, and the optical measuring instrument 1 can be taken out to directly carry out the mapping operation.
