Description

Technical Field

[0001] The utility model belongs to the technical field of land surveying, in particular to a surveying device for surveying and demarcation. Background Art

[0002] Surveying and demarcation is a technical service work that is carried out to define the scope of land use, measure the location of boundaries, map the current land use status, calculate the land area, and provide scientific and accurate basic data for land use approval and cadastral management of the administrative department of land and resources based on the needs of land expropriation, requisition, allocation, transfer, conversion of agricultural land, land use planning, and land development, consolidation, and reclamation.

[0003] Among them, after searching, it was found that there is an application number CN202122839053.0, which discloses a measuring device for surveying and demarcation, including a base, a handle movably installed in the middle above the base, and a pulling handle movably installed on one side of the base. The tape measure is wound up and connected to the winding wheel, and a circular hole is opened on the tape measure, so that one end of the tape measure can be fixed to the starting end through a positioning column, and then the pulling handle is turned out, and the pulling handle is pulled by hand to pull the entire device to move along the edge of the measuring area. When a corner is reached, just insert a positioning column into the circular hole of the tape measure at the corner, and after measuring the angle at the corner, the device can continue to be pulled to move to the next corner, which greatly improves the convenience and work efficiency of the device, while also improving the accuracy of the device's measurement.

[0004] However, after research, it was found that the device uses a tape measure to measure the survey boundary. During the measurement process, the tape measure is easily worn, has a short service life, and is easily worn out, making the scale lines on the surface of the tape measure difficult to read. During the measurement process, there is no structure to clean up impurities on the ground, and the impurities on the ground will affect the accuracy of the measurement data. Therefore, a new device is provided to solve this problem. Utility Model Content

[0026] The staff fixes the connecting ring 1013 at the starting end of the measuring rope roll 1012 at the measurement starting point and turns the limit bolt 1023. The limit bolt 1023 moves downward and pushes the bracket 102 downward, so that the pressure wheel 1021 presses the measuring rope to contact the ground, and the displacement sensor 1022 contacts the measuring rope. Then, the measuring box 1 is pulled along the boundary to move. The displacement sensor 1022 detects the moving distance of the measuring rope roll 1012 until the pressure wheel 1021 moves to the boundary end point. At this time, the displacement data detected by the displacement sensor 1022 is the boundary length. After the measurement is completed, the hand wheel 1011 is rotated to reel in the measuring rope.

Then, the limiting bolt 1023 is tightened, and the limiting bolt 1023 moves downward to push the bracket 102 downward, so that the pressure wheel 1021 presses the measuring rope to contact the ground, and the displacement sensor 1022 contacts the measuring rope, and then pulls the measuring box 1 to move along the demarcation, and the servo motor 1031 drives the scraper 103 to rotate 120° back and forth. The scraper 103 scrapes the large impurities in the delimiting area to both sides of the delimiting area, the brush plate 1034 sweeps away the fine impurities in the delimiting area, and the displacement sensor 1022 detects the moving distance of the measuring rope roll 1012. When encountering a bending area, the two insertion rods B1061 at the bottom of a line fixing rod 106 are inserted across the measuring rope to the ground at the bending point to fix the measuring rope at the bending point until the pressure wheel 1021 moves to the delimiting end point. At this time, the displacement data detected by the displacement sensor 1022 is the delimiting length. Finally, the line end fixing rod 105 and the line fixing rod 106 are removed from the ground, and the hand wheel 1011 is rotated to reel in the measuring rope.
