Description

Technical Field

[0001] The present invention relates to the technical field of measuring devices, in particular to a measuring device for land planning. Background Art

[0002] With the rapid development of science and technology, the requirements for measurement accuracy in the field of land planning are increasing. Traditional measurement methods can no longer meet the needs of modern land management and planning. In this context, GPS surveying instruments, as a high-precision and high-efficiency measurement and positioning mark, have gradually become the first choice in the field of land planning. When using them, staff are often required to set up the base station and move with the measurement and positioning mark to detect the distance data between them and the base station during the movement.

[0003] The accuracy and stability of the measuring device have a decisive influence on the accuracy of the planning results. Traditional measuring devices have many defects in leveling. When using traditional measuring devices, workers are required to first set up the positioning signal base station in a position, and then move it with the measurement positioning mark to perform measurements. The base station located in the original position is easily affected by the interference of the environment and loses its horizontal balance. At this time, the workers in the distance cannot quickly get accurate prompts. After discovering the situation, they need to move a long distance to adjust the base station, which makes the working time longer. In the case of complex external environment, the measuring device may not be able to maintain a horizontal state for a long time during the operation, thus affecting the accuracy of the measurement results.

[0030] The mounting base 1 is provided with a survey mechanism on the upper surface of the mounting base 1, and the survey mechanism includes a leveling component.

An adjustment level plate 5 is provided on the upper surface of the rotating pile 30, and a limiting plate 5 is provided on the side surface of the adjustment level plate 5. Side ring 21, the inner upper surface of the limiting box body 4 is provided with a limiting ring plate 23 that cooperates with the limiting side ring 21, and a plurality of connecting springs 24 are provided between the limiting ring plate 23 and the inner upper surface of the limiting box body 4. The bottom surface of the adjusting horizontal plate 5 is provided with a bottom contact ring 33, and the upper surface of the adjusting base plate 28 is provided with a limiting annular groove 29 that cooperates with the bottom contact ring 33. The upper surface of the adjusting horizontal plate 5 is provided with a horizontal observation port 20, and the center of the upper surface of the adjusting horizontal plate 5 is provided with a top mounting rod 17, and the upper surface of the top mounting rod 17 is provided with an anchor mounting rod 19, and a positioning signal base station is installed above the anchor mounting rod 19. 6. A small camera 18 is also provided above the horizontal observation port 20. One side surface of the small camera 18 is connected to the side surface of the top mounting rod 17. The leveling assembly also includes a mobile pole 10. A measurement positioning mark 11 is provided above the mobile pole 10. A signal connection is established between the measurement positioning mark 11 and the positioning signal base station 6. A data meter 13 is provided on one side surface of the mobile pole 10. An additional panel 14 is provided on one side surface of the data meter 13. An observation screen is provided on the surface of the additional panel 14. A signal connection is established between the additional panel 14 and the small camera 18. A control button is also provided on the surface of the additional panel 14.

[0031] When in use, the staff first uses the mounting base plate 1 to set the positioning signal base station 6 at the designated position and fix it through the supporting assembly. Then, the measuring positioning mark 11 is installed above the mobile pole 10, and the mobile pole 10 is driven to move, while the positioning signal base station 6 remains at the designated position to locate the measuring positioning mark 11. In the process of the staff driving the mobile pole 10 to move, after arriving at the designated detection positioning point, the staff learns the position distance between the measuring positioning mark 11 and the positioning signal base station 6 through the observation data instrument 13, thereby obtaining the detection data. The staff can use the horizontal observation port 20 and the small camera 18 to monitor the horizontal state of the positioning signal base station 6 in real time. When the positioning occurs, the staff can use the horizontal observation port 20 and the small camera 18 to monitor the horizontal state of the positioning signal base station 6 in real time. When the signal base station 6 is affected by special factors in the environment, such as wind, etc., which causes it to no longer maintain horizontal stability, the staff can operate and adjust it on the additional panel 14 through the control button. First, the electric telescopic rod 27 is driven by the signal to retract, driving the lifting base block 22 to descend. When the lifting base block 22 descends, the rotating pile 30 above it also descends synchronously. The meshing gears 32 on both sides of the rotating pile 30 contact the meshing rack 31 as they descend, and produce a meshing effect. Subsequently, the staff can drive the small electrode 35 according to the deflection of the bubble in the horizontal mirror above the horizontal observation port 20, and rotate the small electrode 35 in different directions according to different deflections. During the rotation process of the small electrode 35 The meshing plate 36 moves with the meshing effect with the threaded rod 37, and drives the two meshing racks 31 to move to one side. As the meshing rack 31 moves, the meshing gear 32 drives the top mounting rod 17 to rotate to one side through the meshing effect with the meshing rack 31, so that the entire adjustment level plate 5 is offset. Subsequently, the electric telescopic rod 27 rises, driving the lifting base block 22 and the rotating pile 30 to rise, so that the two meshing gears 32 lose the meshing effect with the meshing rack 31. Subsequently, the driving motor 25 is driven to drive the upper rotating base 26 and the adjustment level plate 5 to rotate. After rotating one circle to reach a horizontal state, the electric telescopic rod 27 drops again, and gradually moves out of the meshing effect of the meshing rack 31 and the meshing gear 32. Gradually adjust the deflection angle of the horizontal plate 5 until the horizontal plate 5 reaches a horizontal state. After the deflection reaches the maximum angle, the bottom contact ring 33 on the bottom surface of the horizontal plate 5 contacts the limiting annular groove 29. When the horizontal plate 5 is rotated, the bottom contact ring 33 rolls inside the limiting annular groove 29 to increase stability during rotation. The limiting side ring 21 on one side of the horizontal plate 5 is tilted upward due to the deflection and finally contacts the limiting ring plate 23. When the horizontal plate 5 is rotated, the limiting side ring 21 is restricted by the limiting ring plate 23 and the connecting spring 24 as it rotates, and cooperates with the bottom contact ring 33 at the bottom to improve the stability of the horizontal plate 5 at the maximum deflection angle. The horizontal angle is found through gradual angle adjustment and rotation.This allows the horizontal plate 5 to be fine-tuned on the horizontal plane until it reaches a horizontal state.

[0032] The survey mechanism also includes a rain shield assembly, which is installed on the upper surface of the mounting base 1 and the surface of the mobile pole 10. The rain shield assembly includes: two fixed plate bodies 7, which are respectively arranged on the bottom surface of the limiting box body 4 and the upper side surface of the mobile pole 10. The side surface of the fixed plate body 7 is provided with four rotatable rain shield frames 8. The connection between the fixed plate body 7 and the rain shield frame 8 is provided with an axis body. The upper surface of the rain shield frame 8 is provided with a rotatable folding rain shield plate 9. The connection between the rain frame body 8 and the folding rain shield 9 is also provided with an axis body, and the upper surface of the folding rain shield 9 is provided with an inclined top plate 12. The upper surface of the fixed plate body 7 is still provided with four fixing protrusions 49 respectively cooperating with the four rain shield frames 8. A sliding sleeve 16 is further provided at the center of the fixed plate body 7 of the rain shield assembly above the mobile pole 10. Two fixed sleeves 15 are further provided on the surface of the mobile pole 10. The sliding sleeve 16 is located between the two fixed sleeves 15 and can slide.

[0033] During use, if it rains during outdoor use, the staff will rotate the four rotatable rain shield frames 8 on the fixed plate body 7 upwards and assemble the four folded rain shields 9 at the end to form a whole plate to provide rain protection. The inclined top plate 12 can make the rainwater falling on the top flow around to prevent the equipment from getting damp and ensure the dryness of the measuring equipment. The rain shield assembly on the surface of the mobile pole 10 can be pulled downward by the staff to separate the sliding sleeve 16 from the fixed sleeve 15 located above when it is not in use and has not been flipped and assembled, and the entire rain shield assembly can be slid down and the sliding sleeve 16 can be engaged with the fixed sleeve 15 located below. At this time, the four rain shield frames 8 located below can be temporarily used as support frames, so that the equipment can be placed upright on the ground for a short time, increasing portability during use.

[0034] The surveying mechanism also includes a support assembly, which includes: three support frames 2, all of which are arranged on the bottom surface of the mounting base plate 1, the bottom surface of the support frame 2 is provided with a retractable extension leg 3, the bottom of the extension leg 3 is provided with a fixed pin 40, and one side surface of the fixed pin 40 is provided with a pedal 39, a rotatable internal frame 41 is provided at the center of the extension leg 3, an axis is provided between the connection between the internal frame 41 and the storage groove 38, a rotatable sliding plate 42 is provided at the center of the internal frame 41, the upper surface of the sliding plate 42 is provided with a bearing plate 43, the side surface of the sliding plate 42 is provided with a sliding side groove 44, the one side surface of the sliding plate 42 is provided with a limiting plate 45 and a bottom support plate 46, the upper surface of the bottom support plate 46 is provided with a limiting protrusion 47, and the bottom surface of the bottom support plate 46 is provided with a bottom surface anti-slip teeth 48;

[0035] When in use, the support assembly consists of three support frames 2, and each support frame 2 is equipped with a retractable extension leg 3 at the bottom. By adjusting the length of the extension leg 3, it can adapt to different terrain heights. The fixed pins 40 are inserted into the ground to increase stability. The pedals 39 are convenient for users to step on to fix the pins. The design of the internal frame 41 and the sliding plate 42 inside the extension leg 3 allows further adjustment of the stability and height of the support frame. The sliding plate 42 slides on the internal frame 41 through the sliding side groove 44. The limiting plate 45 and the bottom support plate 46 provide additional support and stability. The bottom anti-slip teeth 48 on the bottom support plate 46 ensure the stability of the support assembly on various terrains.

[0036] The working principle of the present invention is:

[0037] When in use, the staff first uses the mounting base plate 1 to set the positioning signal base station 6 at the designated position and fix it through the supporting assembly. Then, the measuring positioning mark 11 is installed above the mobile pole 10, and according to the data indication on the observation data instrument 13, the mobile pole 10 is driven to move, while the positioning signal base station 6 remains at the designated position to locate the position of the measuring positioning mark 11. In the process of the staff driving the mobile pole 10 to move, after arriving at the designated detection positioning point, the staff knows the position distance between the measuring positioning mark 11 and the positioning signal base station 6 through the observation data instrument 13, thereby obtaining the detection data. In the process of the staff driving the mobile pole 10 to move, the staff can use The horizontal state of the positioning signal base station 6 is monitored in real time by the horizontal observation port 20 and the small camera 18. When the positioning signal base station 6 is affected by special factors in the environment, such as wind blowing, and no longer maintains horizontal stability, the staff can operate and adjust it on the additional panel 14 through the control button. First, the electric telescopic rod 27 is driven by the signal to retract, driving the lifting base block 22 to descend. When the lifting base block 22 descends, the rotating pile 30 above it also descends synchronously. The meshing gears 32 on both sides of the rotating pile 30 contact the meshing rack 31 as they descend, and produce a meshing effect. Subsequently, the staff can adjust the small electrode 3 according to the deflection of the bubble in the horizontal mirror above the horizontal observation port 20. 5 is driven, and the small rotating electrode 35 rotates in different directions according to the different deflections. During the rotation of the small electrode 35, the meshing plate 36 moves with the meshing effect with the threaded rod 37, and drives the two meshing racks 31 to move to one side. As the meshing rack 31 moves, the meshing gear 32 drives the top mounting rod 17 to rotate to one side through the meshing effect with the meshing rack 31, so that the entire adjustment level plate 5 is offset. Subsequently, the electric telescopic rod 27 rises, driving the lifting base block 22 and the rotating pile 30 to rise, so that the two meshing gears 32 lose the meshing effect with the meshing rack 31. Subsequently, the driving motor 25 is driven to drive the upper rotating base 26 and the adjustment level plate 5 to rotate. After the horizontal state is reached after one rotation, the electric telescopic rod 27 drops again, and the deflection angle of the horizontal plate 5 is gradually adjusted by the meshing effect of the meshing rack 31 and the meshing gear 32 until the horizontal plate 5 is adjusted to the horizontal state. When the deflection is to the maximum angle, the bottom contact ring 33 on the bottom surface of the horizontal plate 5 is adjusted to contact with the limiting annular groove 29. When the horizontal plate 5 is adjusted to rotate, the bottom contact ring 33 rolls inside the limiting annular groove 29 to increase the stability during rotation, and the limiting side ring 21 on one side of the horizontal plate 5 is warped upward due to the deflection, and finally contacts with the limiting ring plate 23. When the horizontal plate 5 is adjusted to rotate, the limiting side ring 21 will be restricted by the limiting ring plate 23 and the connecting spring 24 as it rotates.Cooperating with the bottom contact ring 33 at the bottom, the stability of the adjustment level plate 5 at the maximum deflection angle is improved. By gradually adjusting the angle and rotating to find the horizontal angle, the adjustment level plate 5 can be fine-tuned on the horizontal plane until it reaches a horizontal state.

[0038] During use, if it rains during outdoor use, the staff will rotate the four rotatable rain shield frames 8 on the fixed plate body 7 upwards and assemble the four folded rain shields 9 at the end to form a whole plate to provide rain protection. The inclined top plate 12 can make the rainwater falling on the top flow around to prevent the equipment from getting damp and ensure the dryness of the measuring equipment. The rain shield assembly on the surface of the mobile pole 10 can be pulled downward by the staff to separate the sliding sleeve 16 from the fixed sleeve 15 located above when it is not in use and has not been flipped and assembled, and the entire rain shield assembly can be slid down and the sliding sleeve 16 can be engaged with the fixed sleeve 15 located below. At this time, the four rain shield frames 8 located below can be temporarily used as support frames, so that the equipment can be placed upright on the ground for a short time, increasing portability during use.
