Description

Technical Field

[0001] The invention relates to the technical field of geographical surveying and mapping, and in particular to a multi-angle slope surveying and mapping device for national land space planning. Background Art

[0002] National land space planning refers to the comprehensive planning and arrangement of the development, utilization, protection, and restoration of national land space resources such as land and ocean at the national level. It is a guide for national space development, a spatial blueprint for sustainable development, and the basic basis for various development, protection, and construction activities. The purpose of national land space planning is to achieve the rational allocation, efficient utilization, and effective protection of national land space resources, and to promote the coordinated unity of economic and social development and ecological environmental protection. In the process of land space planning, in addition to surveying and mapping the land, it is also necessary to survey and map the slopes. The flatness of the slope is an important consideration because it is related to the stability of the slope, soil erosion, visual impact, and subsequent land use.

[0003] After searching, it is found that there are problems in the process of geographical surveying of land in the prior art. Since the staff will use the surveying instrument to survey the land, in addition to the land itself, the staff also need to survey the slope. The slope itself is inclined at a certain angle. When using the surveying instrument to survey the slope, the staff may place the surveying instrument on the ground on one side of the slope, and then adjust the surveying instrument to make it level for surveying. At this time, the viewing angle of the surveying instrument is horizontal and the slope itself is inclined, resulting in a certain angle between the two. The data obtained by the measurement cannot be used directly and needs to be converted by certain calculations. At the same time, the slope The slope is not horizontal, and the slope may be uneven, which blocks the line of sight, making it difficult for the surveyor to directly observe certain parts of the slope, making it difficult for the surveyor to accurately measure the flatness of the slope, and the surveying effect is poor. On the other hand, in the prior art, when using a surveyor to survey slopes, it may be necessary to change the angle of the surveyor. The change in the angle of the surveyor may cause the position of its center of gravity to change and not be in the same straight line as the center of gravity of the bracket. The offset of the center of gravity may cause the bracket to be subjected to greater force, causing the bracket to tilt. The tilt of the bracket also causes the surveyor to tilt, further reducing the surveying accuracy, affecting the staff's reasonable planning of the land. Therefore, based on the above search and combined with the prior art, a multi-angle slope surveying device for national land space planning is proposed to solve the above problems.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] In a typical implementation of this application, please refer to Figures 1 to 12 A multi-angle slope surveying and mapping device for national land space planning includes a bracket 1, a bottom plate 2 is installed on the top surface of the bracket 1, a bearing plate 4 is arranged on the top surface of the bottom plate 2, a support plate 5 is fixedly installed on the top surface of the bearing plate 4, a surveying and mapping instrument body 6 is arranged on the top surface of the support plate 5, and is used for geographical surveying and mapping, a corrugated sleeve 3 is installed between the bottom plate 2 and the bearing plate 4, and is used to connect the bottom plate 2 and the bearing plate 4, the corrugated sleeve 3 is a rubber structure, and two fixing rings are fixedly installed on the outer circular wall surface of the corrugated sleeve 3, and the fixing rings on the corrugated sleeve 3 are respectively connected to the bottom plate 2 and the bearing plate 4 by bolts, so as to facilitate subsequent disassembly.

[0033] The surveying and mapping mechanism 7 is arranged on the outer circumferential wall surface of the support plate 5 for surveying and mapping. The surveying and mapping mechanism 7 includes two baffles 13. The two baffles 13 are fixedly mounted on the outer circumferential wall surface of the support plate 5. A fixing seat 34 is fixedly mounted on the top surface of the support plate 5. A rotating block 35 is fixedly mounted on the bottom surface of the surveying and mapping instrument body 6. The rotating block 35 is rotatably connected to the fixing seat 34 through a rotating shaft. A rotation angle sensor 36 for measuring the rotation angle is fixedly mounted on one side of the rotating block 35. The rotation angle sensor 36 can measure the rotation angle of the rotating block 35 and then measure the rotation angle of the surveying and mapping instrument body 6.

[0034] Two mounting seats 30 are installed on the top surface of the support plate 5 by bolts, and a winding roller 31 is rotatably connected to the inside of the mounting seat 30 through a bearing, and a connecting rope 32 is wound around the outer circumferential wall of the winding roller 31. The upper end of the connecting rope 32 is universally connected to the bottom surface of the surveying instrument body 6 through a universal joint. A servo motor 33 for driving the winding roller 31 to rotate is installed on one side of the mounting seat 30, and one end of the driving shaft of the servo motor 33 passes through the mounting seat 30 and is fixedly connected to one end of the winding roller 31. A laser scanner 24 for measuring the inclination of the slope is fixedly installed on the top surface of the support plate 5. The laser scanner 24 obtains spatial data of the slope surface by emitting a laser beam and receiving the laser reflected from the slope surface.

[0035] Among them, the flatness of the slope surface usually refers to the horizontality of the slope surface, that is, whether the slope surface is uniform and whether there are protruding or concave parts. The flatness of the slope surface is an important consideration because it is related to the stability of the slope, soil erosion, visual impact and subsequent land use.

[0036] The surveying and mapping mechanism 7 also includes a wireless centroid 28, which is fixedly mounted on the top surface of the supporting plate 4. The wireless centroid 28 is used to detect the position of the center of gravity of the support plate 5 and the surveying and mapping instrument body 6 as a whole. The staff sets the center position of the wireless centroid 28 as a reference point, and this reference point is on the same straight line as the center of gravity of the bracket 1. The top surface of the baffle 13 is rotatably connected to a connecting frame 39. Two warning lights 22 for warning are fixedly mounted on the top surface of the support plate 5. After the surveying and mapping instrument body 6 is rotated to the same inclination angle as the slope, the warning light 22 emits a light alarm when the center of gravity of the support plate 5 and the surveying and mapping instrument body 6 as a whole deviates from the reference point on the wireless centroid 28 due to the change in the angle of the surveying and mapping instrument body 6.

[0037] A servo motor 38 for driving the connecting frame 39 to rotate is installed on the bottom surface of the baffle 13, one end of the driving shaft of the servo motor 38 passes through the baffle 13 and is fixedly connected to the bottom surface of the connecting frame 39, a positioning frame 42 is installed on the lower end of the connecting frame 39 through bolts, a fixing frame 44 is fixedly installed on the bottom surface of the positioning frame 42, a movable rod 45 is slidably connected inside the fixing frame 44, and two connecting pipes 46 are slidably connected to the movable rod 45, an electric push rod 3 43 for driving the movable rod 45 to move is fixedly installed on the inner top surface of the positioning frame 42, one end of the telescopic shaft of the electric push rod 3 43 passes through the fixing frame 44 and is fixedly connected to the top surface of the movable rod 45, a counterweight frame 55 is fixedly installed on the bottom surface of the fixing frame 44, two support tubes 50 are fixedly installed on the inner bottom surface of the fixing frame 44, a movable plate 49 is slidably connected inside the support tube 50, and one side of the movable plate 49 is fixed A support arm 51 is fixedly installed, and a clamping plate 52 is fixedly installed on the bottom surface of the support arm 51. A limiting column 48 is fixedly installed at the notch of the fixed frame 44. The support arm 51 is slidably connected to the limiting column 48, and the limiting column 48 can limit the movement of the support arm 51 and the clamping plate 52. A plurality of counterweight blocks 53 are arranged on the inner bottom surface of the counterweight frame 55. A positioning column 54 is fixedly installed on the inner bottom surface of the counterweight frame 55, and the counterweight block 53 is slidably connected to the positioning column 54, and the positioning column 54 can position the counterweight block 53. The clamping plate 52 is a U-shaped structure so that it can clamp the counterweight block 53. One side of the connecting pipe 46 is rotatably connected to a connecting rod 2 56 through a rotating shaft, and one end of the connecting rod 2 56 is rotatably connected to one side of the support arm 51 through a rotating shaft. One side of the connecting pipe 46 is rotatably connected to a connecting rod 1 47 through a rotating shaft, and one end of the connecting rod 1 47 is rotatably connected to one side of the fixed frame 44 through a rotating shaft.

[0038] A PLC controller is fixedly installed on the top surface of the support plate 1 5 , and the warning light 22 , the wireless center of gravity meter 28 , the servo motor 1 33 , the angle sensor 36 , the servo motor 2 38 and the electric push rod 3 43 are all electrically connected to the PLC controller.

[0039] By adopting the above technical solution, through the setting of the surveying instrument body 6, when using the surveying instrument body 6 for geographic surveying, the staff will place the bracket 1 on the ground so that the bracket 1 supports the support plate 1 5 and the surveying instrument body 6, and then use the surveying instrument body 6 to collect geographic information.

[0040] On the other hand, the slope is also an important factor to consider in land planning. Therefore, it is also necessary to survey the slope in national land space planning, and use the surveying instrument body 6 to measure the flatness of the slope. The staff first uses the laser scanner 24 to measure the inclination of the slope. After the inclination data is obtained, it will be transmitted to the PLC controller. The drive shaft of the servo motor 33 on one side of the surveying instrument body 6 rotates to drive the winding roller 31 to rotate. The rotation of the winding roller 31 causes the connecting rope 32 to reel up. The winding of the connecting rope 32 on one side causes the surveying instrument body 6 to tilt and rotate toward one side of the slope. The rotation of the surveying instrument body 6 drives the rotating block 35 to rotate between the fixed seat 34 and drives the rotation angle sensor 36 at the same time. The rotation angle sensor 36 can measure the rotation angle of the rotating block 35 and thus know the surveying instrument body 6. The driving shaft of the servo motor 33 on the other side of the surveying instrument body 6 rotates in the opposite direction. The driving shaft of the servo motor 33 rotates in the opposite direction to release the connecting rope 32 on the other winding roller 31. The two connecting ropes 32 are wound and released respectively at the same speed. When the angle measured by the rotation angle sensor 36 is consistent with the inclination angle of the slope, the surveying instrument body 6 stops rotating. At this time, the viewing angle of the surveying instrument body 6 is parallel to the slope, thereby truly reflecting the actual condition of the slope. The surveying and mapping is intuitive, and it is prevented that part of the slope is blocked due to unevenness due to the horizontal viewing angle of the surveying instrument body 6. The measuring viewing angle is parallel to the surface of the slope, which can more accurately obtain the geometric characteristics and spatial information of the slope, and then accurately survey and map the flatness of the slope and collect information.

[0041] On the other hand, the staff sets a reference point on the wireless centroid 28, and then rotates the surveying instrument body 6 to be consistent with the inclination angle of the slope. Since the surveying instrument body 6 tilts to one side, the position of the overall center of gravity of the support plate 5 and the surveying instrument body 6 changes and deviates from the reference point. When the overall center of gravity of the support plate 5 and the surveying instrument body 6 deviates from the reference point, the wireless centroid 28 will transmit a signal to the PLC controller. The PLC controller will activate the warning light 22 after receiving the signal, and the warning light 22 will emit light to alert the staff.

[0042] Then, the number of counterweights 53 in the counterweight frames 55 on both sides of the support plate 1 5 is adjusted by placing the counterweights 53 on the positioning columns 54 or removing them from the positioning columns 54. The staff starts the electric push rod 3 43, and the telescopic shafts of the electric push rod 3 43 move toward each other to drive the movable rod 45 to move downward. The movable rod 45 moves downward so that the two connecting tubes 46 move inward on the movable rod 45. The inward movement of the connecting tube 46 causes the connecting rod 1 47 to rotate downward. The downward movement of the movable rod 45 also causes the connecting rod 2 56 to rotate downward. The connecting rod 2 56 rotates downward so that the movable plate 49 moves inward inside the support tube 50. The movable plate 49 moves inwardly, driving the support arm 51 to move inwardly along the limit column 48. The limit column 48 can limit the movement of the support arm 51. The support arm 51 moves inwardly, driving the clamping plate 52 to move inwardly. The two groups of support arms 51 and the clamping plate 52 move inwardly to clamp the counterweight block 53 inside the counterweight frame 55. The support arm 51, the clamping plate 52 and the positioning column 54 cooperate to position the counterweight block 53 to prevent the counterweight block 53 from shaking. The change in the number of counterweight blocks 53 on both sides of the support plate 5 causes the counterweight on both sides of the support plate 5 to change, which is convenient for adjusting the position of the overall center of gravity of the support plate 5 and the surveying instrument body 6.

[0043] At the same time, the staff starts two servo motors 2 38 respectively through the PLC controller. The rotation of the driving shaft of the servo motor 2 38 drives the connecting frame 39 to rotate. The rotation of the connecting frame 39 drives the fixed frame 2 44, the counterweight frame 55 and the counterweight block 53 to rotate, thereby adjusting the angle of the counterweight block 53 on both sides of the support plate 1 5, and then further adjusting the position of the center of gravity of the support plate 1 5 and the surveying instrument body 6 until the overall center of gravity of the support plate 1 5 and the surveying instrument body 6 coincides with the reference point on the wireless centroid 28. At this time, the overall center of gravity of the support plate 1 5 and the surveying instrument body 6 is in the same straight line as the center of gravity of the bracket 1, preventing the bracket 1 from tilting during long-term use due to the change in the center of gravity position of the surveying instrument body 6, and avoiding the angle of the surveying instrument body 6 changing due to the tilt of the bracket 1, improving the stability of the bracket 1 supporting the support plate 1 5 and the surveying instrument body 6, so that the viewing angle of the surveying instrument body 6 is always consistent with the inclination angle of the slope, further improving the accuracy of the surveying instrument body 6 when measuring the flatness of the slope.

[0044] In this process, the ground can be surveyed and geographical information can be collected by looking straight through the surveying and mapping instrument body 6. On the other hand, by adjusting the angle of the surveying and mapping instrument body 6, the inclination angle of the surveying and mapping instrument body 6 is made the same as the inclination angle of the slope, so that the viewing angle of the surveying and mapping instrument body 6 is parallel to the slope, and the actual condition of the slope is truly reflected to survey and map the flatness of its inclined surface, thereby improving the accuracy of surveying and mapping the slope, and comprehensively considering the land surface, the slope and its flatness to carry out land planning, and then by adjusting the number and angle of the counterweight blocks 53 on both sides of the support plate 5, the center of gravity of the support plate 5 and the surveying and mapping instrument body 6 as a whole is made to be in the same straight line as the center of gravity of the bracket 1, so as to prevent the bracket 1 from tilting during long-term use due to the change in the center of gravity position of the surveying and mapping instrument body 6, and to avoid the angle of the surveying and mapping instrument body 6 changing due to the inclination of the bracket 1, thereby further improving the accuracy of the surveying and mapping instrument body 6 when surveying the flatness of the slope, thereby achieving the surveying and mapping effect of the land, and facilitating the staff to carry out land space planning for the land.

[0045] An arc groove 37 is provided on the top surface of the baffle 13, and the cross-section of the arc groove 37 is T-shaped. A mounting column 40 is slidably connected inside the arc groove 37, and a roller 41 is rotatably connected to the bottom surface of the mounting column 40 via a rotating shaft. The top surface of the mounting column 40 is fixedly connected to the inner top surface of the connecting frame 39. The rotation of the connecting frame 39 drives the mounting column 40 and the roller 41 to slide inside the arc groove 37. The arc groove 37, the mounting column 40 and the roller 41 can limit the rotation of the connecting frame 39 and reduce the shaking of the connecting frame 39.

[0046] Specifically, by setting up the connecting frame 39, the connecting frame 39 rotates to drive the mounting column 40 to move inside the arc groove 37, and the movement of the mounting column 40 inside the arc groove 37 also causes the roller 41 to rotate in the arc groove 37. The mounting column 40 and the roller 41 can support the connecting frame 39 and reduce the shaking of the connecting frame 39, while the roller 41 can reduce the friction between the mounting column 40 and the arc groove 37, thereby improving the smoothness of the rotation of the connecting frame 39.

[0047] As a preferred implementation in this embodiment, please refer to Figures 1 to 9 The bottom surface of the surveying instrument body 6 is provided with a support plate 3 29 for supporting the surveying instrument body 6, and the top surface of the support plate 5 is fixedly installed with an electric push rod 23. The top surface of the telescopic axis of the electric push rod 23 is fixedly connected to the bottom surface of the support plate 3 29. The electric push rod 23 is electrically connected to the PLC controller. During normal surveying, the electric push rod 23 and the support plate 3 29 can support the surveying instrument body 6 to prevent the surveying instrument body 6 from rotating at will. After surveying the slope, the electric push rod 23 drives the support plate 3 29 to move downward to cancel the support for the surveying instrument body 6.

[0048] Specifically, by setting the support plate three 29, during normal surveying, the electric push rod 1 23 and the support plate three 29 can support the surveying instrument body 6 to prevent the surveying instrument body 6 from rotating at will, thereby improving the stability of the surveying instrument body 6. When surveying the slope, the telescopic axis of the electric push rod 1 23 moves downward to drive the support plate three 29 to move downward and separate from the bottom surface of the surveying instrument body 6, thereby canceling the support for the surveying instrument body 6 and facilitating the adjustment of the angle of the surveying instrument body 6.

[0049] The bracket 1 includes a base 8, which is rotatably connected to the bottom surface of the base plate 2. A bearing is installed on the top surface of the base 8. The base plate 2 is rotatably connected to the base 8 through the bearing. The outer circular wall surface of the base plate 2 is provided with a plurality of notches. The upper end of the support frame 9 is rotatably connected in the notch through a rotating shaft. The lower end of the support frame 9 is slidably connected with a support plate 2 10 for inserting into the soil. The upper end of the support plate 2 10 is slidably connected to the support frame 9. The lower end of the support frame 9 is threadedly connected with a screw 11 for locking the support plate 2 10. Thread grooves are provided on both sides of the support plate 2 10. The screw 11 penetrates the lower end of the support frame 9 and is threadedly connected to the inner circular wall surface of the thread groove. A rope 12 for limiting is provided on the bottom surface of the base 8. The three ends of the rope 12 are respectively fixedly connected to the lower ends of the three support frames 9. The rope 12 can support multiple support frames 9.

[0050] Among them, when the staff uses the bracket 1 for surveying, the staff inserts multiple support plates 10 into the soil, and the ropes 12 can limit the angles of the three support frames 9. The staff moves the surveying instrument body 6 upward to drive the support frame 9 to move upward. The support frame 9 moves upward along the support plate 10 until the surveying instrument body 6 is moved to a suitable height and then the height of the surveying instrument body 6 is locked with the screw 11, so that the bracket 1 is used to support the surveying instrument body 6 to ensure the stability of the surveying instrument body 6 on the ground.

[0051] Specifically, through the support frame 9, during the surveying process, the staff rotates the multiple support frames 9 outward until the rope 12 is straightened, and the rope 12 can limit the angle of the support frame 9. Then the staff inserts the lower ends of the multiple support plates 10 into the soil. The support frames 9 and the support plates 10 can support the base 8. The staff moves the surveying instrument body 6 upward to drive the support frame 9 to move upward. The support frame 9 moves upward along the support plate 10 until the surveying instrument body 6 is moved to a suitable height and then the height of the surveying instrument body 6 is locked with the screw 11, so that the bracket 1 is used to support the surveying instrument body 6, and then the surveying instrument body 6 is stabilized in a suitable position to prevent the surveying instrument body 6 from tipping over.

[0052] A support hole 16 is provided on the top surface of the base 8, and a magnet 20 for limiting the bottom plate 2 is slidably connected to the inner circular wall surface of the support hole 16. The bottom plate 2 is an iron disc-shaped structure. A fixing frame 17 is fixedly installed on the inner bottom surface of the base 8, and a mounting rod 18 is slidably connected to the bottom surface of the fixing frame 17. The top surface of the mounting rod 18 is fixedly connected to the bottom surface of the magnet 20, and the outer circular wall surface of the mounting rod 18 is sleeved with a spring 19 for resetting the magnet 20. One end of the spring 19 is fixedly connected to the bottom surface of the magnet 20, and the other end of the spring 19 is fixedly connected to the inner bottom surface of the fixing frame 17.

[0053] The staff moves the installation rod 18 downward to drive the magnet 20 to move downward and compress the spring 19 at the same time. After the magnetic attraction of the magnet 20 is lost, the staff rotates the surveying instrument body 6 to drive the base plate 2 to rotate. After the surveying instrument body 6 is rotated to a suitable angle, the staff releases the installation rod 18. The magnet 20 is reset under the action of the spring 19 and magnetically attracts the base plate 2 again, thereby determining the angle of the surveying instrument body 6.

[0054] Specifically, through the set surveying instrument body 6, in the process of using the surveying instrument body 6 for geographic surveying, the staff needs to adjust the angle of the surveying instrument body 6, the staff moves the mounting rod 18 downward, the mounting rod 18 moves downward inside the fixing frame 17, drives the magnet 20 to move downward and compresses the spring 19, the staff moves the magnet 20 to the outside of the support hole 16 through the mounting rod 18, and the magnet 20 loses its adsorption, the staff rotates the surveying instrument body 6 to drive the bottom plate 2 to rotate, the staff rotates the surveying instrument body 6 to a suitable angle and then releases the mounting rod 18, the force of the spring 19 causes the mounting rod 18 to drive the magnet 20 to move upward until the magnet 20 contacts the bottom surface of the bottom plate 2, at which time the magnet 20 can adsorb the bottom plate 2, thereby determining the angle of the surveying instrument body 6, thereby achieving the effect of adjusting the angle of the surveying instrument body 6, and facilitating the staff to perform geographic surveying from various angles.

[0055] The top surface of the base 8 is provided with an annular groove 14 for supporting the rotation of the base plate 2. The inner rotatable connection of the annular groove 14 is provided with a support ring 15. The top surface of the support ring 15 is fixedly connected to the bottom surface of the base plate 2. The cross-sections of the annular groove 14 and the support ring 15 are both T-shaped structures, which improve the rotation stability of the base plate 2 and the surveying instrument body 6. The inner bottom surface of the annular groove 14 is provided with a plurality of grooves. The inner rotatable connection of the grooves is provided with balls, which reduce the friction between the support ring 15 and the annular groove 14.

[0056] Specifically, the bottom plate 2 is arranged, and the rotation of the bottom plate 2 drives the support ring 15 to rotate inside the annular groove 14 . The annular groove 14 and the support ring 15 cooperate to limit the rotation of the bottom plate 2 , thereby achieving a limiting effect on the bottom plate 2 .

[0057] A gyroscope 21 for detecting the level of the carrying plate 4 is installed on the top surface of the carrying plate 4, and a plurality of support blocks 25 are fixedly installed on the top surface of the bottom plate 2. A connecting block 26 is rotatably connected between every two support blocks 25. A second electric push rod 27 is fixedly installed on one side of the connecting block 26. The top surface of the second electric push rod 27 is universally connected to the bottom surface of the carrying plate 4 through a universal joint. The gyroscope 21 and the second electric push rod 27 are electrically connected to the PLC controller.

[0058] Among them, the gyroscope 21 can detect the horizontal state of the supporting plate 4. The gyroscope 21 can detect the tilt of the support plate 1 5 and the surveying instrument body 6. The telescopic axis of multiple electric push rods 27 moves outward or contracts to keep the support plate 1 5 and the surveying instrument body 6 level, thereby avoiding the influence of the tilt of the surveying instrument body 6 on the surveying.

[0059] Specifically, through the arrangement of the bracket 1, the bracket 1 may tilt due to the uneven ground during use. The tilt of the bracket 1 causes the load-bearing plate 4, the support plate 1 5 and the surveying instrument body 6 to tilt. When the gyroscope 21 on the load-bearing plate 4 detects the tilt, it transmits the information to the PLC controller. The PLC controller processes the information and feeds back the information to the multiple electric push rods 27. The telescopic axes of the multiple electric push rods 27 move outward or contract to adjust the position of the load-bearing plate 4, and at the same time, the electric push rods 27 drive the connecting block 26 to rotate between the support blocks 25, so that the load-bearing plate 4 remains horizontal, and then the support plate 1 5 and the surveying instrument body 6 are always horizontal, so as to avoid the surveying and mapping being affected by the tilt of the surveying instrument body 6.

[0060] Working principle: Through the set bracket 1, when the staff uses the bracket 1 for surveying, the staff inserts multiple support plates 10 into the soil, and the rope 12 can limit the angle of the three support frames 9. The staff moves the surveying instrument body 6 upward to drive the support frame 9 to move upward. The support frame 9 moves upward along the support plate 10 until the surveying instrument body 6 is moved to a suitable height and then the height of the surveying instrument body 6 is locked with the screw 11, so that the bracket 1 is used to support the surveying instrument body 6 to ensure the stability of the surveying instrument body 6 on the ground.

[0061] Secondly, the gyroscope 21 can detect the horizontal state of the supporting plate 4. The gyroscope 21 can detect the tilt of the supporting plate 5 and the surveying instrument body 6, and the telescopic axis of multiple electric push rods 27 moves outward or contracts to keep the supporting plate 5 and the surveying instrument body 6 level, thereby avoiding the influence of the tilt of the surveying instrument body 6 on the surveying.

[0062] Next, the land is geographically surveyed through the surveying instrument body 6. During normal surveying, the electric push rod 1 23 and the support plate 3 29 can support the surveying instrument body 6 to prevent the surveying instrument body 6 from rotating at will. After surveying the slope, the electric push rod 1 23 drives the support plate 3 29 to move downward, canceling the support for the surveying instrument body 6.

[0063] Subsequently, when using the surveying instrument body 6 to measure the flatness of the slope surface, the staff first uses the laser scanner 24 to measure the inclination of the slope surface. After obtaining the inclination data, the servo motor 33 on one side of the surveying instrument body 6 drives the winding roller 31 to rotate and wind up the connecting rope 32. At this time, the servo motor 33 on the other side of the surveying instrument body 6 reversely drives the winding roller 31 to release the connecting rope 32 and the two have the same speed. The connecting rope 32 on one side of the surveying instrument body 6 is wound up to make the surveying instrument body 6 rotate and tilt to one side. The rotation of the surveying instrument body 6 drives the rotating block 35 and the angle sensor 36 to rotate. When the rotation angle detected by the angle sensor 36 is consistent with the inclination angle of the slope surface, the rotation of the surveying instrument body 6 is stopped. At this time, the surveying instrument body 6 can measure the flatness of the slope surface from a parallel direction, which is more accurate than looking straight ahead.

[0064] At the same time, after the surveying instrument body 6 is rotated to the same angle as the slope inclination, the surveying instrument body 6 tilts to one side, causing the position of the overall center of gravity of the support plate 1 5 and the surveying instrument body 6 to change and deviate from the reference point. When the overall center of gravity of the support plate 1 5 and the surveying instrument body 6 deviates from the reference point, the warning light 22 is activated to alert the staff, and the staff adjusts the number of counterweights 53 on both sides of the support plate 1 5, and then the electric push rod 3 43 drives the movable rod 45 to move downward. The movable rod 45 moves downward, causing the connecting pipe 46 to slide inward on the movable rod 45. The inward sliding of the connecting pipe 46 drives the connecting rod 1 47 to rotate downward, and the movable rod 45 moves downward through The movable plate 49 and the support arm 51 are moved inwardly through the connecting rod 2 56, and the inward movement of the support arm 51 drives the clamping plate 52 to move inwardly to clamp the counterweight block 53. At the same time, the servo motor 2 38 drives the connecting frame 39 to rotate, and the rotation of the connecting frame 39 drives the counterweight frame 55 and the counterweight block 53 to rotate. The counterweight frames 55 and the counterweight blocks 53 on both sides rotate respectively to further adjust the overall center of gravity of the support plate 1 5 and the surveying instrument body 6 so that the center of gravity falls on the reference point of the wireless centroid meter 28, thereby preventing the stability of the bracket 1 from being affected by adjusting the angle of the surveying instrument body 6, thereby better measuring and mapping the flatness of the slope slope and realizing multi-angle mapping of the surveying instrument body 6.

[0065] Finally, the staff moves the mounting rod 18 downward to drive the magnet 20 downward and compress the spring 19. After the magnetic attraction of the magnet 20 is lost, the staff rotates the surveying instrument body 6 to drive the base plate 2 to rotate. After the surveying instrument body 6 is rotated to a suitable angle, the staff releases the mounting rod 18. The magnet 20 is reset under the action of the spring 19 and magnetically attracts the base plate 2 again, thereby determining the angle of the surveying instrument body 6.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
