Description

Technical Field

[0001] The present invention belongs to the technical field of topographic surveying, and specifically relates to a topographic surveying device for territorial spatial planning and its surveying method. Background Technique

[0002] Urban planning is to standardize the development and construction of cities, study the future development of cities, the rational layout of cities, and the comprehensive arrangement of various urban engineering constructions. It is a comprehensive deployment, a blueprint for the development of cities within a certain period, an important part of urban management, the basis for urban construction and management, and also a prerequisite for the three stages of urban planning, urban construction, and urban operation. In the urban planning process, the surface flatness of the to-be-developed terrain is often measured to ensure the subsequent smooth development, and a flatness measuring device is usually used.

[0003] After retrieval, a Chinese patent document with the authorization announcement number of CN 116147468 B discloses a topographic flatness measuring device for urban planning. It converts the up-and-down displacement into the relative separation or relative approach of the guide blocks, and converts the relative approach or relative separation of the guide blocks into pressure to realize the movement of the colored liquid. By matching the colored liquid input into the first temporary storage tank and the second temporary storage tank with the scale on the outer side, the flatness of the ground can be directly obtained. The whole process is relatively visual, and there is no need for complex operations. Just push the device to the measurement point to measure the ground undulation, without the need to stop moving and then measure, realizing the function of dynamically measuring the ground flatness during the movement process.

[0004] The above device converts the protrusions and depressions on the ground into the power of up-and-down undulation to realize the movement of the color liquid for the visualization of the measurement structure. However, when the terrain area to be measured is large, the canvas and paintbrush need to be replaced regularly during the measurement process, and the measurement work needs to be aborted, thus affecting the work efficiency; in addition, the chart presented by the paintbrush and canvas can only obtain the final measurement data by experienced staff, and the measurement method has limitations.

[0020] The embodiments of the topographic survey device for national territorial space planning according to the present invention will be described below according to its overall structure.

[0021] A topographic survey device for national territorial space planning, as Figures 1 to 10 shown, includes a driving base plate 100. A cleaning component 200 for cleaning ground obstacles (referring to leaves, plant roots and stones on the ground) is assembled at the front end of the driving base plate 100. An ultrasonic detection component 300 for measuring the terrain is assembled directly above the driving base plate 100. A support frame 120 for supporting the ultrasonic detection component 300 is fixed on the top of the driving base plate 100 to keep the support frame 120 balanced; The ultrasonic detection assembly 300 includes a load-bearing square bar 310 fixed at the center position of the top of the support frame 120, and the top of the load-bearing square bar 310 is respectively provided with a first display panel 320 that rotates in two directions, and the end of each group of first display panels 320 is connected to a second display panel 330 through a hinge, and the lower surface of the second display panel 330 is equipped with two groups of ultrasonic detector assemblies 370, and the top of the second display panel 330 is provided with an I-shaped cable wheel 360, and the outer wall of the I-shaped cable wheel 360 is wound with a cable 361, one end of the cable 361 extends to the top of the first display panel 320 and is fixed, and the other end of the cable 361 is fixed to the curved outer wall of the I-shaped cable wheel 360, and the bottom of the I-shaped cable wheel 360 is fixed to a transmission sleeve 366 that penetrates the bottom of the second display panel 330, and 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; The ultrasonic detector assembly 370 includes a shell 371 fixed to the bottom of the second display board 330, a transmission sleeve 366 passes through the shell 371 and extends into the ultrasonic detector assembly 370 below, a movable ring 368 rotating in the shell 371 is fixed to the outer wall of the transmission sleeve 366, and multiple groups of frame members 374 are arranged at equal intervals on both sides of the movable ring 368 in the shell 371, and each group of frame members 374 is equipped with an ultrasonic detector 375 at the bottom, and multiple groups of frame members 374 on the same side are rotatably connected with a rhombus hinge frame 376 inside, and the end of the rhombus hinge frame 376 is provided with a connecting bar 379 rotatably connected to the bottom end of the movable ring 368, and a bottom cover 372 is fixed to the bottom of the shell 371 by bolts, and a clearance groove 373 for multiple groups of ultrasonic detectors 375 to slide horizontally is provided at the bottom of the bottom cover 372; The ultrasonic detection assembly 300 also includes a driving arm group 340 rotatably disposed on the front and rear surfaces of the load-bearing square bar 310 and used to drive the first display board 320 and the second display board 330 to fold. The driving arm group 340 includes two groups of active arms 342 rotatably disposed on the front and rear surfaces of the load-bearing square bar 310. The end of each group of active arms 342 is rotatably connected to a first connecting arm 343, and the outer walls of the two groups of first connecting arms 343 are rotatably connected to the front and rear surfaces of the first display board 320 through a second base shaft 346. The end of the second base shaft 346 is rotatably provided with a second connecting arm 344. The outer wall of the second connecting arm 344 and near the end position is fixed with a first base shaft 345. The two groups of first base shafts 345 are rotatably connected to the front and rear surfaces of the second display board 330. The front and rear surfaces of the first display board 320 and the second display board 330 are both fixed with U-shaped restraint plates 350 for restraining the first connecting arm 343 and the second connecting arm 344. A receiving groove 311 is formed 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. Both ends of the positioning shaft 341 are fixedly connected to the driving arm group 340. A driven gear 314 is fixedly mounted on the outer wall of each group of positioning shafts 341. The two ends of the positioning shaft 341 extend outside the load-bearing square bar 310 and are fixedly connected to the driving arm group 340. Circular holes for the positioning shaft 341 to rotate are formed in the inner and outer walls of the load-bearing square bar 310. A second driving motor 312 is assembled above one group of the positioning shafts 341 in the receiving groove 311. The output end of the second driving motor 312 is connected with a driving gear 313 for driving the driven gear 314 to rotate. A transmission gear 315 connected to the inner wall of the receiving groove 311 is rotatably provided at the middle position between the two groups of driven gears 314.

[0022] Move the device to the terrain surface to be measured. At this time, control the second driving motor 312 to work. Its output end drives the driving gear 313 to rotate, driving the driven gear 314 to rotate. Through the transmission of the transmission gear 315, the two groups of driven gears 314 rotate synchronously. Through the transmission of the positioning shaft 341, the two groups of driving arms 342 on the front and rear surfaces of the load-bearing square bar 310 rotate upward, and drive the first connecting arm 343 to rotate. The first connecting arm 343 rotates around the second base shaft 346 as the center, generating an upward external force on the first display board 320, causing the first display board 320 to rotate around the connection point at the top of the load-bearing square bar 310. 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 board 330 to rotate and unfold around the hinge until the first display board 320 and the second display board 330 are horizontally placed on both sides of the load-bearing square bar 310 (as Figure 1 shown). At this time, the ultrasonic detector assembly 370 at the bottom of the second display board 330 faces the ground; When the first display board 320 and the second display board 330 are unfolded to a horizontal state, the cable 361 will be in a taut state, driving the I-shaped cable wheel 360 to rotate and release the cable 361, so that the first display board 320 and the second display board 330 are completely in an unfolded state. When the I-shaped cable wheel 360 rotates, it drives one set of ultrasonic detector components 370 to rotate and unfold through the transmission sleeve 366, and is in a state perpendicular to the second display board 330. The moving ring 368 on the outer wall of the transmission sleeve 366 rotates synchronously, rotates around the axis of the I-shaped cable wheel 360, and the angle of the traction link 379 changes. The link 379 will gradually change from an inclined state to a state parallel to the housing 371. The link 379 will generate a lateral thrust on the diamond hinge frame 376, increasing the distance between multiple sets of frame members 374, and the ultrasonic detector 375 assembled at the bottom slides linearly along the relief groove 373 to complete the adjustment of the distance between adjacent two sets of ultrasonic detectors 375. The ultrasonic detector 375 in the other set of ultrasonic detector components 370 will also expand outward, thereby increasing the area measured on the ground and improving the accuracy of the terrain measurement data.

[0023] Please refer particularly to Figures 6 to 9 , a shallow groove 321 corresponding to the thickness dimension of the I-shaped cable wheel 360 is provided on the upper surface of the first display board 320. Two constraint rings fixed to the top of the second display board 330 and in the shallow groove 321 are sleeved on the outer wall of the cable 361. A wheel shaft 362 connected to the top of the transmission sleeve 366 is fixed to the bottom of the I-shaped cable wheel 360. A torsion spring 363 connected inside the second display board 330 is provided on the outer wall of the wheel shaft 362. A through positioning hole 331 is provided at the contact position between the top of the second display board 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, which can generate a reverse torsion force on the wheel shaft 362. When the I-shaped cable wheel 360 is no longer pulled by the cable 361 (that is, when the first display board 320 and the second display board 330 are in a folded state), it will drive the wheel shaft 362 and the I-shaped cable wheel 360 to rotate and reset). A screw 367 passing through the transmission sleeve 366 and threadedly connected to the bottom of the wheel shaft 362 is provided at the bottom of the transmission sleeve 366. A threaded hole 365 matching the screw 367 is provided at the bottom of the wheel shaft 362. A polygonal groove 364 is provided outside the threaded hole 365 at the bottom of the wheel shaft 362. A polygonal ring 369 inserted into the polygonal groove 364 is fixed to the top of the transmission sleeve 366; The shallow groove 321 is used to provide a storage space for the I-shaped cable wheel 360, so that the first display board 320 and the second display board 330 in the folded state are not restricted. The setting of the constraint ring plays a limiting role on the cable 361 in a relaxed state (that is, when the first display board 320 and the second display board 330 are in a folded state), avoiding the cable 361 from being hooked by other components and affecting the unfolding action of the first display board 320 and the second display board 330; The torsion spring 363 can restore the wheel shaft 362 after rotation, so that the I-shaped cable wheel 360 rotates to reel in the cable 361; The screw 367 can flexibly connect the transmission sleeve 366 to the bottom of the axle 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 components 370 to be accurately installed in parallel at the bottom of the second display board 330.

[0024] Please refer to Figure 8 and Figure 9 The bottom of the transmission sleeve 366 extends into the lower shell 371, the outer wall of the transmission sleeve 366 is fixedly connected to the lower shell 371 and the end thereof extends to the bottom of the moving ring 368, the top of the moving ring 368 is fixed with two groups of connecting rods 380 extending to the top of the shell 371, the top of the shell 371 is provided with an arc groove 377 that enables the connecting rods 380 to rotate 90°, and the tops of the two groups of connecting rods 380 are fixedly connected to the bottom cover 372 in the upper ultrasonic detector assembly 370; 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 the contact position.

[0025] When the transmission sleeve 366 rotates, the lower shell 371 rotates 90° accordingly and is perpendicular to the second display plate 330, and the movable ring 368 in the upper shell 371 rotates, but the movable 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 movable ring 368 in the upper shell 371 with the upper bottom cover 372, all the internal parts of the lower shell 371 except the movable 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.

[0026] Please refer to Figure 10 A rectangular groove 378 corresponding to the thickness of the rhombus hinge frame 376 is opened in the middle of each set of frame members 374, and the central hinge point of the rhombus hinge frame 376 is rotatably connected to the central position of the upper and lower inner walls of the rectangular groove 378.

[0027] 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 finally driving multiple groups of ultrasonic detectors 375 to unfold, so as to achieve the purpose of measuring large-area terrain.

[0028] Please refer to Figure 1, the support frame 120 includes an outer ring 122 located above the drive base plate 100. Three groups of support arms 121 fixed to the top of the drive base plate 100 are provided on the curved outer wall of the outer ring 122. An inner ring 140 is rotatably provided inside the outer ring 122 through a first connecting shaft. A support platform 130 is rotatably connected to the inner side of the inner ring 140 through a second connecting shaft. The top of the support platform 130 is fixedly arranged with the bottom of the load-bearing square bar 310. A counterweight platform 150 is additionally installed at the bottom of the support platform 130. A central control box 110 is assembled below the counterweight platform 150 at the top of the drive base plate 100.

[0029] During the process of the central control box 110 driving the drive base plate 100 to move, the stability of the ultrasonic detection component 300 is improved through the inner ring 140, the outer ring 122 and the counterweight platform 150, and the influence of inclination on the terrain measurement result can be avoided; At the same time, the central control box 110 is used to receive instructions and control the operation of each electronic device in the device, so as to realize the efficient measurement operation of the terrain.

[0030] Please refer specifically to Figure 2 and Figure 3 , the cleaning component 200 includes two groups of cleaning rollers 230 arranged in front of the drive base plate 100. Positioning arms 210 fixed to the bottom of the drive base plate 100 are rotatably provided at both ends of each group of cleaning rollers 230. A first drive motor 220 for driving the cleaning rollers 230 to rotate is assembled on the outer wall of one of the positioning arms 210. A baffle 240 is provided on the side of the cleaning roller 230 close to the front surface of the drive base plate 100, and both ends of the baffle 240 are fixed to the inner wall of the positioning arm 210. A plurality of dredging rods 250 are equidistantly distributed in a linear array at the bottom of the baffle 240; A plurality of ball head rods are equidistantly distributed along the contour of the curved surface on the outer wall of the cleaning roller 230. Each group of dredging rods 250 is located at the position between two adjacent groups of ball head rods.

[0031] 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. The leaves, plant roots and stones on the ground are cleaned through the ball head rods, ensuring that the ultrasonic detector 375 behind can normally measure the ground. Since the baffle 240 is in a fixed state, the dredging rods 250 will stand upright at the vacant positions between two adjacent groups of ball head rods, remove the leaves, plant roots and stones stuck in, and at the same time, the baffle 240 can block the stones cleared to prevent the stones from splashing to the rear and damaging the ultrasonic detector 375.

[0032] Detachable movable plates are provided at the corresponding positions of the side wall of the load-bearing square bar 310 and the receiving groove 311.

[0033] The movable plate facilitates the disassembly and repair of the first drive motor 220 inside and the maintenance of the gear set.

[0034] Please refer particularly to Figures 1 to 10 , a measuring method of a topographic survey device for territorial spatial planning, comprising the following steps: S1. Control the driving base plate 100 to move to the starting end position of the terrain to be measured, and then start the second drive motor 312 to rotate its output end. Drive the first display board 320 and the second display board 330 on both sides of the load-bearing square bar 310 to unfold through the drive arm group 340. At this time, the two ultrasonic detector assemblies 370 at the bottom of the second display board 330 face the ground in a cross shape; S2. Control the driving base plate 100 to move on the ground of the terrain to be measured and move towards the end of the terrain to be measured, while the ultrasonic detector assembly 370 faces the ground for measurement, and large-area measurement operations can be carried out on the terrain as the driving base plate 100 moves; S3. The cleaning assembly 200 works synchronously as the driving base plate 100 moves, and can clean leaves, plant roots, stones, etc. on the ground to ensure the accuracy of the ground measurement data of the subsequent ultrasonic detector assembly 370; S4. During the measurement process, the inner ring 140 and the outer ring 122 can rotate along their own axes in two horizontal directions, 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 terrain measurement data of the ultrasonic detection assembly 300.
