Description

Technical Field

[0001] This invention relates to the field of measurement technology, specifically to a topographic flatness measuring device for land planning. Background Technology

[0002] Territorial spatial planning serves as a guide for national spatial development and a spatial blueprint for sustainable development. It is the fundamental basis for various development, protection, and construction activities. Establishing a territorial spatial planning system and supervising its implementation involves integrating spatial plans such as functional zoning planning, land use planning, and urban and rural planning into a unified territorial spatial plan, achieving "multi-plan integration," and strengthening the guiding and binding role of territorial spatial planning on various special plans. In territorial spatial planning, it is necessary to measure the flatness of the terrain.

[0003] Chinese invention patent CN113155001A discloses a flatness measuring device for building construction. The patent includes a base, universal wheels with brakes located at the four corners of the lower end of the base, a support vertical beam fixed to the middle of the upper end of the base, a support horizontal beam with one end fixed to the upper end of the support vertical beam and the other end protruding, a drive device, a balancing device, and a measuring dial indicator. The drive device is rotatably fixed to the protruding end of the support horizontal beam, and the upper end of its rotation axis is fixed to one end of a fixed rod. The measuring dial indicator is slidably fixed to the other end of the fixed rod. The bottom surface of the measuring dial indicator and the bottom surface of the universal wheels are on the same horizontal plane.

[0004] Chinese invention patent CN114252048A discloses a terrain flatness measuring device for land spatial planning. This patent includes a base, a testing mechanism, and a marking mechanism. Both the testing mechanism and the marking mechanism are located below the base. Second support blocks are installed at both ends of one side of the outer wall of the top of the base, and a second fixed housing is installed on the outer wall of one opposite end of the two second support blocks. This invention uses a distance sensor mounted on a mounting ring to measure the distance between the sensor and the bottom of the base, thereby calculating the flatness. Because the detection pulleys on both sides are not on the same straight line, a comprehensive measurement of the ground can be achieved. The base, limiting rod, arc-shaped rubber block, arc-shaped rod, vented housing, and brush bristles allow for the pushing and cleaning of the ground to be measured, preventing debris from affecting the movement of the detection pulleys and thus the measurement results.

[0005] The above solution has the following shortcomings: each time a deviation in terrain flatness is detected, the device needs to be stopped and staff need to check and record the results, which reduces the detection efficiency. Furthermore, when the detection equipment is damaged, it needs to be replaced, which increases the detection cycle. In addition, the above solution only records the data of terrain flatness that does not meet the standard, and does not mark the terrain that does not meet the standard. Summary of the Invention

[0006] To address the aforementioned technical problems, a terrain flatness measurement device for land use planning is provided.

[0075] When the device measures the slope of a ditch, the height of the flatness measuring mechanism is adjusted by the adjustable electric push rod so that the flatness measuring mechanism does not come into contact with the ground. This avoids damage to the flatness measuring mechanism due to contact with the ground when measuring the slope of the ditch. The angle measuring mechanism is set in two sets, one set to measure the maximum slope of the ditch and the other set to measure the minimum slope of the ditch, making the device versatile.

[0098] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0099] Reference Figure 1-12 As shown, the topographic flatness measuring device for land planning includes:

[0100] Workbench 1;

[0101] A pigment container 2 is set on a workbench 1 and is fixedly connected to the workbench 1. A telescopic tube 201 is fixedly connected to the pigment container 2. The other end of the telescopic tube 201 passes through the workbench 1 and the connecting plate 702 from top to bottom and communicates with the pigment box 708. A level detector 3 is set on both sides of the pigment container 2 and is fixedly installed on the workbench 1. The level detector 3 is used to detect the horizontal angle of the workbench 1. A connecting groove 4 is set on the rear side of the pigment container 2 and is opened on the workbench 1. A control rod 401 is fixedly connected inside the connecting groove 4. The control rod 401 has a T-shaped structure and is used to control the movement of the workbench 1. Support legs 9 are fixedly connected to the four corners of the bottom of the workbench 1. Universal wheels 901 are fixedly installed at the bottom of the support legs 9.

[0102] It is understandable that the leveling instrument 3 can detect the levelness of the device. If the leveling instrument 3 detects that the device is not parallel to the ground, there will be errors in the measurement of the terrain flatness.

[0103] Two sets of lifting components 5 are symmetrically arranged on the workbench 1. The lifting components 5 are used to adjust the height of the cleaning components 6.

[0104] The cleaning component 6 is located below the workbench 1 and is fixedly connected to the lifting component 5. The cleaning component 6 is used to clean up debris on the ground.

[0105] The flatness measuring mechanism 7 is located on the rear side of the cleaning component 6 and is fixedly connected to the workbench 1. The flatness measuring mechanism 7 is used to measure the flatness of the terrain.

[0106] Two sets of angle measuring mechanisms 8 are symmetrically arranged at the bottom of the workbench 1. The angle measuring mechanisms 8 are fixedly connected to the workbench 1. The angle measuring mechanisms 8 are used to measure the angle of the ditch slope.

[0107] Reference Figure 5-11 As shown, the flatness measuring mechanism 7 includes:

[0108] The adjustable electric actuator 701 is fixedly installed at the bottom of the workbench 1;

[0109] In a specific embodiment, when the device is idle, the adjustable electric push rod 701 extends upward, and the flatness measuring mechanism 7 moves upward synchronously. When the flatness measuring mechanism 7 is suspended in the air, the adjustable electric push rod 701 stops extending, thus preventing the flatness measuring mechanism 7 from being in contact with the ground for a long time and absorbing moisture, which would reduce the service life of the electronic equipment inside the flatness measuring mechanism 7.

[0110] The connecting plate 702 is fixedly connected to the output end of the adjustable electric push rod 701;

[0111] The left side plate 703 is fixedly connected to the connecting plate 702;

[0112] The right side plate 704 is fixedly connected to the connecting plate 702;

[0113] Fixed plate 705 is fixedly connected to left side plate 703;

[0114] The stepper motor 706 is fixedly mounted on the fixed plate 705. The output end of the stepper motor 706 passes through the left side plate 703. The stepper motor 706 is used to switch the measuring roller 713.

[0115] The spindle 707 is fixedly connected to the output end of the stepper motor 706;

[0116] In a particular embodiment, the measuring roller 713 can be switched when the stepper motor 706 controls the spindle 707 to rotate 45 degrees.

[0117] The paint box 708 is fixedly connected to the right side plate 704;

[0118] The first turntable 709 is located on the right side of the stepper motor 706, and the first turntable 709 is fixedly connected to the spindle 707;

[0119] The second turntable 710 is fixedly connected to the paint box 708;

[0120] The third turntable 711 is located to the left of the second turntable 710, and the third turntable 711 is fixedly connected to the main shaft 707;

[0121] Understandably, the first turntable 709, the second turntable 710, and the third turntable 711 are of the same size, ensuring the smooth operation of the device during measurement.

[0122] The first cylinder 712 has a hollow structure and is provided in several groups. The first cylinder 712 is located between the first turntable 709 and the third turntable 711. The end of the first cylinder 712 near the first turntable 709 is provided with a thread.

[0123] Understandably, several sets of connecting holes are provided through the interior of the first cylinder 712 to facilitate the entry of pigment into the measuring roller 713 through the connecting holes.

[0124] The measuring roller 713 is rotatably connected to the first cylinder 712.

[0125] In addition, multiple sets of bristles are installed on the outer surface of the measuring roller 713. The pigment is used to wet the bristles through the connecting hole opened in the first cylinder 712, which facilitates the marking of the terrain.

[0126] The first turntable 709 includes:

[0127] The mounting hole 727 is provided corresponding to the first cylinder 712, and the mounting hole 727 is opened through the left edge of the first turntable 709;

[0128] The fixing cylinder 728 is disposed on both sides of the mounting hole 727. The fixing cylinder 728 has a hollow structure and is fixedly connected to the first turntable 709.

[0129] In a particular embodiment, the fixing cylinder 728 is used to fix the fixing cap 729 and prevent the fixing cap 729 from falling off.

[0130] The outer surface of the fixing cap 729 is slidably connected to the mounting hole 727, and the interior of the fixing cap 729 is threadedly connected to the first cylinder 712.

[0131] In a specific embodiment, to install the measuring roller 713, first insert the unthreaded end of the measuring roller 713 into the second feeding channel 720, then insert the threaded end of the measuring roller 713 into the mounting hole 727, insert the fixing cap 729 from the other end of the mounting hole 727, rotate the measuring roller 713, and the measuring roller 713 is inserted into the mounting hole 727 along the direction of the thread, thus completing the installation of the measuring roller 713.

[0132] The second turntable 710 includes:

[0133] A through hole 714 is located at the center of the right side of the second turntable 710, and the through hole 714 is connected to the paint box 708;

[0134] The material conveying pipes 715 are provided in several groups. The material conveying pipes 715 are arranged in a circumferential array along the through hole 714. The material conveying pipes 715 are opened inside the second turntable 710. One end of the material conveying pipe 715 is connected to the through hole 714.

[0135] The switching valve 716 is correspondingly installed with the material conveying pipe 715, and the switching valve 716 is rotatably connected to the second turntable 710;

[0136] Understandably, when the device is idle, the switching valve 716 closes all the first feed channels 717, so there is no pigment on the measuring roller 713, avoiding pigment evaporation and reducing costs.

[0137] The first feeding channel 717 is correspondingly provided with the conveying pipe 715. The first feeding channel 717 is located at the left edge of the second turntable 710 and is connected to the conveying pipe 715.

[0138] In a particular embodiment, when the device is performing a measurement operation, only one first feeding channel 717 is connected, while the other first feeding channels 717 are in a closed state.

[0139] Sleeve 718 is fixedly connected to the center of the left side of the second turntable 710, and sleeve 718 is rotatably connected to the main shaft 707.

[0140] The outer diameter of the spindle 707 is the same as that of the sleeve 718, which in certain embodiments prevents the spindle 707 from falling off during operation.

[0141] The third turntable 711 includes:

[0142] The annular groove 719 is located on the right edge of the third turntable 711;

[0143] The second feeding channel 720 is disposed inside the annular groove 719. The second feeding channel 720 is disposed corresponding to the first feeding channel 717. The second feeding channel 720 is opened through the right edge of the third turntable 711.

[0144] The ramp surface 721 is provided inside the annular groove 719, and the ramp surface 721 is provided on both sides of the second feeding channel 720;

[0145] Understandably, the ramp 721 is designed to facilitate switching of the measuring roller 713.

[0146] The second cylinder 722 has a hollow structure. The second cylinder 722 is correspondingly arranged with the second feeding channel 720. The second cylinder 722 is slidably connected with the annular groove 719.

[0147] The third cylinder 723 has a hollow structure and is fixedly connected to the second cylinder 722;

[0148] Spring 724 is fixedly connected to the third cylinder 723;

[0149] The fourth cylinder 725 is a hollow structure, and the fourth cylinder 725 is slidably connected to the third cylinder 723;

[0150] The fifth cylinder 726 is a hollow structure, and the outer surface of the fifth cylinder 726 is threaded. The fifth cylinder 726 is fixedly connected to the fourth cylinder 725.

[0151] In a specific embodiment, when the measuring roller 713 in use is damaged, the stepper motor 706 controls the main shaft 707 to rotate 45 degrees. At the same time, the third cylinder 723 compresses the spring 724 under the action of the stepper motor 706, and part of the third cylinder 723 enters the fourth cylinder 725. The second cylinder 722 slides along the opening direction of the annular groove 719. When the undamaged measuring roller 713 reaches the measuring position, that is, when one end of the measuring roller 713 reaches the second feeding channel 720, the stepper motor 706 stops rotating, and the switching of the measuring roller 713 is completed.

[0152] The size of the annular groove 719 is the same as the diameter of the second cylinder 722, the size of the second feeding channel 720 is the same as the outer diameter of the second cylinder 722, the outer diameter of the third cylinder 723 is the same as the inner diameter of the fourth cylinder 725, the fifth cylinder 726 is threadedly connected to the first feeding channel 717, and the second feeding channel 720 is slidably connected to the first cylinder 712.

[0153] In another specific embodiment, the measuring roller 713 is disassembled, and the fifth cylinder 726 is rotated. Since the fifth cylinder 726 has threads, it leaves the first feeding channel 717 along the direction of the threads. During the rotation of the fifth cylinder 726, the third cylinder 723 compresses the spring 724, causing part of the third cylinder 723 to enter the fourth cylinder 725, which increases the space for the fifth cylinder 726 to rotate out of the first feeding channel 717. After the fifth cylinder 726 leaves the first feeding channel 717, the fourth cylinder 725 can be tilted to remove it. Then, the first cylinder 712 is rotated, and it leaves the fixing cap 729 along the opposite direction of the threads. The operation of removing the fourth cylinder 725 increases the space for rotating the first cylinder 712. When one end of the first cylinder 712 is completely away from the first turntable 709, the first cylinder 712 is pulled out of the third turntable 711, thus completing the disassembly of the measuring roller 713.

[0154] In a specific embodiment, when measuring terrain flatness, the adjustable electric push rod 701 extends downwards. When the bottom set of measuring rollers 713 in the flatness measuring mechanism 7 comes into contact with the top of the terrain to be measured, the adjustable electric push rod 701 stops extending. The operator pushes the device to measure the terrain. Photoelectric sensors and data transmitters are installed at the junctions of the first cylinder 712 with the first turntable 709 and the third turntable 711. When the flatness of the terrain does not meet the standard, it will contact the measuring rollers 713. The paint on the measuring rollers 713 will mark the unqualified terrain areas. At the same time, the data transmitter will send the data measured by the photoelectric sensors to the operator. When the measuring rollers 713 are damaged, the stepper motor 706 controls the main shaft 707 to rotate 45 degrees. The damaged measuring rollers 713 rise, and the intact measuring rollers 713 fall, allowing the operator to continue the terrain flatness measurement operation, reducing the time for the operator to replace the measuring rollers 713 and reducing the operator's workload.

[0160] In a particular embodiment, when a measurement operation is required, the lifting motor 502 adjusts the height of the cleaning assembly 6.

[0167] When designing a ditch slope, there is a acceptable slope range. The minimum slope of the slope cannot be less than the minimum slope of the acceptable range, and the maximum slope of the slope cannot be greater than the maximum slope of the acceptable range. Therefore, the angle measuring mechanism 8 is set up in two sets: one set measures the maximum slope of the ditch slope, and the other set measures the minimum slope of the ditch slope.

[0168] Angle measuring mechanism 8 includes:

[0169] The slide rail 801 is provided in two sets, and the two sets of slide rail 801 are symmetrically arranged at the bottom end of the worktable 1. The slide rail 801 is fixedly installed at the bottom end of the worktable 1.

[0170] The first slide block 802 is slidably connected to the slide rail 801;

[0171] When the device performs a measurement operation, the first slide 802 and the second slide 807 slide on the slide rail 801, which can adjust the distance between the adjusting electric push rod 803 and the matching electric push rod 808 to adapt to ditches of different widths and ditch slopes of different heights.

[0172] The electric adjustment push rod 803 is fixedly installed on the first slide block 802;

[0173] The first fixed frame 804 is fixedly connected to the output end of the adjusting electric push rod 803;

[0174] The unwinding motor 805 is fixedly installed on the outside of the first fixed frame 804, and the output end of the unwinding motor 805 passes through the outside of the first fixed frame 804.

[0175] The unwinding reel 806 is fixedly connected to the output end of the unwinding motor 805;

[0176] The dimensions of the unwind reel 806 are the same as those of the take-up reel 811. When the device is idle, the unwind reel 806 and the take-up reel 811 are located on the same horizontal plane.

[0177] The second slide block 807 is slidably connected to the slide rail 801;

[0178] The electric actuator 808 is fixedly installed on the second slide block 807;

[0179] In a specific embodiment, the electric push rod 803 and the matching electric push rod 808 are used together to make the unwinding reel 806 and the winding reel 811 located at different heights. Therefore, the measuring line 812 between the unwinding reel 806 and the winding reel 811 forms a certain angle with the bottom of the ditch, and then the slope of the ditch is measured using the measuring line 812.

[0180] The second fixed frame 809 is fixedly connected to the output end of the matching electric push rod 808;

[0181] The winding motor 810 is fixedly installed on the outside of the second fixed frame 809, and the output end of the winding motor 810 passes through the outside of the second fixed frame 809;

[0182] The unwinding motor 805 and the take-up motor 810 rotate in the same direction, ensuring that the measuring line 812 is kept taut.

[0183] The winding reel 811 is fixedly connected to the output end of the winding motor 810;

[0184] One end of the angle measuring line 812 is wound around the unwinding reel 806, and the other end of the angle measuring line 812 is wound around the take-up reel 811;

[0185] In another specific embodiment, the angle measuring line 812 is soaked in pigment before use, and is removed when a measurement operation is required.

[0186] In a specific embodiment, when it is necessary to measure the slope of a ditch slope, the flatness measuring mechanism 7 is first suspended by adjusting the electric push rod 701 to prevent it from contacting the ground and causing damage. Two sets of angle measuring mechanisms 8 are provided. Adjusting the front angle measuring mechanism 8 allows the first slide 802 and the second slide 807 to slide on the slide rail 801, so that the distance between the first slide 802 and the second slide 807 of the front angle measuring mechanism 8 is consistent with the distance at the bottom edge of the slope. When designing the ditch slope, the slope has a acceptable range. Adjusting the electric push rod 803 upwards so that the bottom end of the unwinding reel 806 is at the same level as the top of the slope, and adjusting the electric push rod 808 downwards so that the bottom end of the winding reel 811 is at the same level as the bottom of the slope. On the surface, the angle of the measuring line 812 between the unwinding reel 806 and the winding reel 811 is located at the minimum slope of the qualified slope range. The unwinding motor 805 and the winding motor 810 keep the measuring line 812 taut. The operation of the rear angle measuring mechanism 8 is the same as that of the front angle measuring mechanism 8, but the angle of the rear angle measuring line 812 is located at the maximum slope of the qualified slope range. The staff pushes the device to measure the slope of the ditch. If the slope is greater than the maximum slope or less than the minimum slope, the measuring line 812 marks it and transmits the data to the staff simultaneously.

[0187] The working principle and usage process of this invention are as follows: When measuring the flatness of the terrain, the position of the angle measuring mechanism 8 is adjusted so that the angle measuring mechanism 8 does not contact the ground. The distance adjusting electric push rod 701 adjusts the position of the flatness measuring mechanism 7 so that the measuring roller 713 is in contact with the terrain to be measured. The operator pushes the device to measure the flatness of the terrain. The measuring roller 713 marks the areas where the flatness is not up to standard and transmits the data of the unqualified data to the operator.

[0188] When measuring the slope of a ditch, the position of the flatness measuring mechanism 7 is adjusted by the adjustable electric push rod 701, so that the flatness measuring mechanism 7 is suspended in the air. Then, the distance between the first slide 802 and the second slide 807 in the angle measuring mechanism 8 is adjusted. Finally, the height of the unwinding reel 806 and the rewinding reel 811 is adjusted so that the angle of the measuring line 812 is consistent with the qualified slope of the slope. The staff can then push the device to complete the measurement of the ditch slope.

[0189] The device is equipped with multiple sets of measuring devices. When one set fails, only the backup measuring device needs to be switched without stopping the measurement process, which effectively shortens the measurement cycle. In addition, the device is also equipped with a ditch slope measuring device, which makes the device more versatile and reduces its limitations.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
