As the driving base plate moves, the measurement range of the topography is expanded, and the accuracy of the data results is improved.

Description

Technical Field

[0001] The present invention belongs to the technical field of topographic surveying, and in particular relates to a topographic surveying device for national land space planning and a surveying method thereof. Background Art

[0002] Urban planning regulates urban development and construction, studies the city's future growth, rationalizes its layout, and comprehensively arranges various urban construction projects. It serves as a blueprint for urban development over a specific period of time, a crucial component of urban management, and the basis for urban construction and management. It is also the prerequisite for the three phases of urban planning, urban construction, and urban operation. In urban planning regulations, the surface flatness of the terrain to be developed is often measured to ensure smooth subsequent development, and flatness measuring devices are often used.

[0003] After searching, a Chinese patent document with authorization publication number CN 116147468 B discloses a terrain flatness measurement device for urban planning. This device converts vertical displacement into the relative distance or proximity of guide blocks, and converts the relative proximity or distance of the guide blocks into pressure to achieve the movement of colored liquid. The flatness of the ground is directly determined by the colored liquid input into the interior of the first and second temporary storage tanks in conjunction with the scales on the outer surfaces. The entire process is relatively visual and does not require complex operations. The device only needs to be pushed to the test point to measure the ground undulations. There is no need to stop the device for measurement, thus realizing the function of dynamic measurement of ground flatness during movement.

[0004] The above-mentioned device converts the bumps and depressions of the ground into up and down momentum to realize the movement of the colored liquid to facilitate the visualization of the measured structure. However, when the terrain area to be measured is large, the canvas and brush need to be replaced regularly during the measurement process, and the measurement work needs to be suspended, which affects work efficiency. In addition, the chart presented by the brush and canvas can only rely on experienced staff to obtain the final measurement data, and the measurement method has limitations. Summary of the Invention

DETAILED DESCRIPTION

[0037] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be understood as limiting the present invention.

[0038] The following describes an embodiment of the land space planning topographic surveying device based on its overall structure according to the present invention.

[0039] A land space planning topographic survey device, such as Figures 1 to 10 As shown, it includes a driving base plate 100, a cleaning assembly 200 for clearing ground obstructions (referring to leaves, plant roots and stones on the ground) is installed at the front end of the driving base plate 100, an ultrasonic detection assembly 300 for measuring terrain is installed directly above the driving base plate 100, and a support frame 120 for supporting the ultrasonic detection assembly 300 is fixed on the top of the driving base plate 100 to keep the support frame 120 balanced;

[0040] The ultrasonic detection assembly 300 includes a load-bearing square bar 310 fixed to the center position of the top of the support frame 120. The top of the load-bearing square bar 310 is provided with a first display panel 320 that rotates in two directions. The end of each group of first display panels 320 is connected to the second display panel 330 by a hinge. The lower surface of the second display panel 330 is equipped with two groups of ultrasonic detector assemblies 370. The top of the second display panel 330 is provided with an I-shaped cable pulley 360. The outer wall of the I-shaped cable pulley 360 is wrapped with a cable 361. One end of the cable 361 extends to the top of the first display panel 320 and is fixed. The other end of the cable 361 is fixed to the curved outer wall of the I-shaped cable pulley 360. The bottom of the I-shaped cable pulley 360 is fixed to a transmission sleeve 366 that passes through the bottom of the second display panel 330. The transmission sleeve 366 is rotatably arranged in the second display panel 330 and can drive one group of ultrasonic detector assemblies 370 to rotate.

[0041] The ultrasonic detector assembly 370 includes a housing 371 fixed to the bottom of the second display panel 330, a transmission sleeve 366 passing through the housing 371 and extending into the ultrasonic detector assembly 370 below, a movable ring 368 rotating in the housing 371 fixed to the outer wall of the transmission sleeve 366, a plurality of groups of frame members 374 arranged at equal intervals on both sides of the movable ring 368 in the housing 371, and an ultrasonic detector 375 mounted on the bottom of each group of frame members 374, a diamond-shaped hinge frame 376 being rotatably connected to the inside of the plurality of groups of frame members 374 on the same side, a connecting bar 379 being rotatably connected to the bottom end of the movable ring 368 being provided at the end of the diamond-shaped hinge frame 376, a bottom cover 372 being fixed to the bottom of the housing 371 by bolts, and a clearance groove 373 being provided at the bottom of the bottom cover 372 for the plurality of groups of ultrasonic detectors 375 to slide laterally;

[0042] The ultrasonic detection assembly 300 also includes a driving arm group 340 that is rotatably disposed on the front and rear surfaces of the load-bearing square bar 310 and is used to drive the first display panel 320 and the second display panel 330 to fold. The driving arm group 340 includes two sets of active arms 342 that are rotatably disposed on the front and rear surfaces of the load-bearing square bar 310. The end of each set of active arms 342 is rotatably connected to a first connecting arm 343, and the outer walls of the two sets of first connecting arms 343 are rotatably connected to the front and rear surfaces of the first display panel 320 via a second base shaft 346. The end of the second base shaft 346 is rotatably provided with a second connecting arm 344. A first base shaft 345 is fixed to the outer wall of the second connecting arm 344 near the end. The two sets of first base shafts 345 are rotatably connected to the front and rear surfaces of the second display panel 330.

[0043] The front and rear surfaces of the first display plate 320 and the second display plate 330 are fixed with U-shaped restraining plates 350 for restraining the first connecting arm 343 and the second connecting arm 344. A receiving groove 311 is opened in the load-bearing square bar 310. Two groups of positioning shafts 341 extending to the front and rear outer sides of the load-bearing square bar 310 are rotatably provided in the receiving groove 311. The two ends of the positioning shafts 341 are respectively fixed to the driving arm group 340. The outer wall of each group of positioning shafts 341 is fixed with a driven gear 314. The two ends of the positioning shafts 341 are fixed with a driven gear 314. The end of the load-bearing square bar 310 is extended to the outside and fixed to the driving arm group 340. The inner and outer walls of the load-bearing square bar 310 are provided with circular holes for the rotation of the positioning shaft 341. A second driving motor 312 is installed above one group of positioning shafts 341 in the accommodating groove 311. The output end of the second driving motor 312 is connected to a driving gear 313 for driving the driven gear 314 to rotate. A transmission gear 315 connected to the inner wall of the accommodating groove 311 is rotatably provided in the middle of the two groups of driven gears 314.

[0044] The device is moved to the terrain surface to be measured, and the second driving motor 312 is controlled to work, and its output end drives the driving gear 313 to rotate, driving the driven gear 314 to rotate. The transmission gear 315 transmits the two sets of driven gears 314 to rotate synchronously, and the positioning shaft 341 transmits the two sets of driving arms 342 located on the front and rear surfaces of the load-bearing square bar 310 to rotate upward, and drives the first connecting arm 343 to rotate. The first connecting arm 343 rotates with the second base axis 346 as the center of the circle, generating an upward external force on the first display panel 320, causing the first display panel 320 to rotate around the connection point at the top of the load-bearing square bar 310, and at this time, the second connecting arm 344 rotates with the connection point with the first connecting arm 343 as the base point, causing the second display panel 330 to rotate and unfold around the hinge until the first display panel 320 and the second display panel 330 are horizontally placed on both sides of the load-bearing square bar 310 (such as Figure 1 As shown), at this time, the ultrasonic detector assembly 370 located at the bottom of the second display panel 330 faces the ground;

[0045] When the first display panel 320 and the second display panel 330 are unfolded to a horizontal state, the cable 361 is tightened, which drives the I-shaped cable wheel 360 to rotate and release the cable 361, so that the first display panel 320 and the second display panel 330 are fully unfolded. When the I-shaped cable wheel 360 rotates, it drives one group of ultrasonic detector components 370 to rotate and unfold through the transmission sleeve 366, and is perpendicular to the second display panel 330. The dynamic ring 368 on the outer wall of the transmission sleeve 366 rotates synchronously therewith and rotates along the axis of the I-shaped cable wheel 360 as the center of the circle, and pulls the ultrasonic detector components 370 to rotate and unfold. The angle of the connecting rod 379 changes, and the connecting rod 379 will gradually change from an inclined state to a state parallel to the shell 371. The connecting rod 379 will generate a lateral thrust on the diamond-shaped hinge frame 376, so that the spacing between the multiple groups of frame members 374 becomes larger, and the ultrasonic detectors 375 assembled at the bottom slide linearly along the give way groove 373 to complete the adjustment of the spacing between the two adjacent groups of ultrasonic detectors 375, and the ultrasonic detectors 375 in the other group of ultrasonic detector assemblies 370 will also expand outward, thereby increasing the area measured on the ground and improving the accuracy of the terrain measurement data.

[0046] Please refer to Figures 6 to 9 The upper surface of the first display plate 320 is provided with a shallow groove 321 corresponding to the thickness of the I-shaped cable wheel 360. The outer wall of the cable 361 is provided with two sets of constraint rings fixed to the top of the second display plate 330 and the shallow groove 321. The bottom of the I-shaped cable wheel 360 is fixed with a wheel shaft 362 connected to the top of the transmission sleeve 366. The outer wall of the wheel shaft 362 is provided with a torsion spring 363 connected to the second display plate 330. A through positioning hole 331 is provided at the contact position between the top of the second display plate 330 and the torsion spring 363 (the torsion spring 363 is sleeved on the outer wall of the wheel shaft 362 and cooperates with the positioning hole 331 to adjust the wheel shaft 362 The reverse torque is generated. When the I-shaped cable pulley 360 is no longer pulled by the cable 361 (i.e., the first and second display panels 320, 330 are folded), the wheel shaft 362 and the I-shaped cable pulley 360 are driven to rotate and return to their original position. A screw 367 is provided at the bottom of the transmission sleeve 366, passing through the transmission sleeve 366 and threadedly connected to the bottom of the wheel shaft 362. A threaded hole 365 is defined at the bottom of the wheel shaft 362, which mates with the screw 367. A polygonal groove 364 is defined outside the threaded hole 365, aligned with the bottom of the wheel shaft 362. A polygonal ring 369 is fixed to the top of the transmission sleeve 366 and inserted into the polygonal groove 364.

[0047] The shallow groove 321 is used to provide storage space for the I-shaped cable pulley 360, so that the first and second display panels 320 and 330 are not constrained when folded. The restraining ring is provided to limit the position of the cable 361 in a relaxed state (i.e., when the first and second display panels 320 and 330 are folded), preventing the cable 361 from getting hooked on other components and affecting the unfolding movement of the first and second display panels 320 and 330.

[0048] The torsion spring 363 can restore the rotated wheel shaft 362, so that the I-shaped cable wheel 360 rotates and reels the cable 361;

[0049] The screw 367 can flexibly connect the transmission sleeve 366 to the bottom of the wheel shaft 362 to facilitate the disassembly and assembly of the ultrasonic detector 375; and the polygonal groove 364 and the polygonal ring 369 cooperate with each other to enable the two sets of ultrasonic detector assemblies 370 to be accurately installed in parallel at the bottom of the second display panel 330.

[0050] Please refer to Figure 8 and Figure 9 The bottom of the transmission sleeve 366 extends into the lower housing 371. The outer wall of the transmission sleeve 366 is fixedly connected to the lower housing 371 and the end thereof extends to the bottom of the dynamic ring 368. The top of the dynamic ring 368 is fixed with two sets of connecting rods 380 extending to the top of the housing 371. The top of the housing 371 is provided with an arc groove 377 that enables the connecting rods 380 to rotate 90 degrees. The tops of the two sets of connecting rods 380 are fixedly connected to the bottom cover 372 in the upper ultrasonic detector assembly 370.

[0051] The housing 371 located at the top is fixed to the bottom of the second display board 330 , and the housing 371 is rotatably connected to the transmission sleeve 366 at a contact position.

[0052] When the transmission sleeve 366 rotates, the lower shell 371 rotates 90° accordingly and becomes perpendicular to the second display plate 330. The dynamic ring 368 located in the upper shell 371 rotates, and the dynamic ring 368 in the lower shell 371 will not be driven. When the lower shell 371 rotates, since the two sets of connecting rods 380 fix the dynamic ring 368 in the square shell 371 with the upper bottom cover 372, all the components in the lower shell 371 except the dynamic ring 368 will rotate, and the opening of the arc groove 377 ensures that the connecting rod 380 will not affect the rotation of the lower shell 371.

[0053] Please refer to Figure 10 A rectangular groove 378 corresponding to the thickness of the diamond-shaped hinge frame 376 is opened in the middle of each set of frame members 374, and the central hinge point of the diamond-shaped hinge frame 376 is rotatably connected to the center position of the upper and lower inner walls of the rectangular groove 378.

[0054] The rectangular groove 378 allows the diamond-shaped hinge frame 376 to rotate in the frame 374 around the center position of the upper and lower inner walls of the rectangular groove 378, thereby changing the distance between two adjacent groups of frame members 374, and ultimately driving multiple groups of ultrasonic detectors 375 to deploy, achieving the purpose of measuring large-area terrain.

[0055] Please refer to Figure 1The support frame 120 includes an outer ring 122 located above the driving base plate 100. The curved outer wall of the outer ring 122 is provided with three groups of support arms 121 fixed to the top of the driving base plate 100. The inner side of the outer ring 122 is rotatably provided with an inner ring 140 through a first connecting shaft. The inner side of the inner ring 140 is rotatably connected to the support platform 130 through a second connecting shaft. The top of the support platform 130 is fixed to the bottom of the load-bearing square bar 310, and a counterweight platform 150 is added to the bottom of the support platform 130. The top of the driving base plate 100 is located below the counterweight platform 150 and is equipped with a central control box 110.

[0056] When the central control box 110 drives the base plate 100 to move, the inner ring 140, the outer ring 122 and the counterweight 150 improve the stability of the ultrasonic detection assembly 300, thereby preventing the tilt from affecting the measurement results of the terrain.

[0057] At the same time, the central control box 110 is used to receive instructions and control the operation of various electronic components in the device, thereby achieving efficient measurement of the terrain.

[0058] Please refer to Figure 2 and Figure 3 The cleaning assembly 200 includes two groups of cleaning rollers 230 arranged in front of the driving base plate 100. The two ends of each group of cleaning rollers 230 are rotatably provided with positioning arms 210 fixed to the bottom of the driving base plate 100. The outer wall of one group of positioning arms 210 is equipped with a first driving motor 220 for driving the cleaning rollers 230 to rotate. A baffle 240 is provided on the side of the cleaning rollers 230 close to the front surface of the driving base plate 100, and the two ends of the baffle 240 are fixed to the inner wall of the positioning arm 210. The bottom of the baffle 240 is evenly distributed with multiple groups of dredging rods 250 in a linear array.

[0060] The first drive motor 220 works together with the drive base plate 100. The output end of the first drive motor 220 will drive the cleaning roller 230 to roll along the connection point with the positioning arm 210, and clean the leaves, plant roots and stones on the ground through the ball head rod to ensure that the ultrasonic detector 375 at the rear can measure the ground normally. Since the baffle 240 is in a fixed state, the dredging rod 250 will be erected in the empty position between the two adjacent sets of ball head rods to clear the stuck leaves, plant roots and stones. At the same time, the baffle 240 can block the cleared stones to prevent the stones from splashing to the rear and damaging the ultrasonic detector 375.

[0061] Removable movable panels are provided at corresponding positions of the side walls of the load-bearing square bar 310 and the receiving groove 311 .

[0062] The movable plate facilitates the disassembly and maintenance of the internal first drive motor 220 and the maintenance of the gear set.

[0063] Please refer to Figures 1 to 10 A measuring method of a land space planning topographic surveying device comprises the following steps:

[0064] S1. Manipulate the driving base plate 100 to the starting position of the terrain to be measured, then start the second driving motor 312 to rotate its output end. The driving arm assembly 340 drives the first and second display panels 320, 330 on both sides of the load-bearing square bar 310 to unfold. At this time, the two ultrasonic detector assemblies 370 located at the bottom of the second display panel 330 are arranged in a cross shape, facing the ground.

[0065] S2. Control the driving base plate 100 to move on the ground of the terrain to be measured and move toward the end of the terrain to be measured, while the ultrasonic detector assembly 370 faces the ground to perform measurements. As the driving base plate 100 moves, a large area of ​​terrain can be measured.

[0066] S3. The cleaning component 200 works synchronously with the movement of the driving base plate 100 to clean leaves, plant roots, and stones on the ground to ensure the accuracy of the ground measurement data of the ultrasonic detector component 370 at the rear;

[0067] S4. During the measurement process, the inner ring 140 and the outer ring 122 can rotate in two horizontal directions along their own axes, and with the cooperation of the counterweight platform 150, the center of gravity of the ultrasonic detection assembly 300 can be stabilized, thereby improving the accuracy of the ultrasonic detection assembly 300 in measuring topographic data.
