Description

Technical Field

[0001] The present invention mainly relates to the field of land planning equipment, and specifically to a land planning marking device for national land space planning. Background Art

[0002] The national land space planning is a guide for national space development, a spatial blueprint for sustainable development, and the basic basis for all kinds of development, protection and construction activities. Establish a national land space planning system and supervise its implementation, integrate the main functional area planning, land use planning, urban and rural planning and other spatial planning into a unified national land space planning, realize "multiple plans in one", and strengthen the guiding and restraining role of national land space planning on various special plans. National land space planning requires a lot of field measurements to obtain sufficient information on the distribution of land before spatial planning of the land is carried out.

[0003] Land surveying is the work of measuring and mapping the quantity, distribution and topography of various types of land using surveying and remote sensing technology. It includes topographic surveying, cadastral surveying, land leveling surveying, current land use surveying, and investigation of reserve resources such as barren hills and wastelands. The surveying methods used include geodetic surveying, general surveying, aerial photogrammetry, remote sensing technology and map compilation. As the national basic topographic map is gradually completed, land surveying mainly refers to other contents besides topographic surveying, and all of them are measured based on the national basic topographic map.

[0004] The existing Chinese patent application with publication number CN117759155A discloses a field measurement device for land space planning, including a mounting frame, a support structure is installed on both sides of the mounting frame, a lifting structure is installed on the mounting frame, and a drilling structure is installed on the lifting structure; the drilling structure includes a lifting frame, a turntable is rotatably installed on the lifting frame, and a spiral auger is installed on the turntable; the supporting structure includes two relatively mounted support rods, an adjustment rod is rotatably installed in the middle of the support rod, a limit rod is installed between the two support rods on the outside of the support frame, a sliding sleeve is slidably installed on the limit rod, and the sliding sleeves are respectively connected to the adjustment rods on both sides; a spring is sleeved on the limit rod, and the two ends of the spring are respectively connected to the sliding sleeve and the primary support plate. This device can assist the operator in land measurement and positioning, fix the device in a certain position through the drilling structure and further perform measurement activities, and improve the stability during use and the flexibility during movement by setting a lifting structure and rollers and other devices.

[0005] However, the field measurement device for national land space planning has the following defects when used: 1. When the land space planning field measurement device uses a measuring ruler such as a soft ruler or a tape measure for measurement, it is necessary to first place one end of the measuring ruler on a fixed point, and then move the measuring ruler to the next measuring point. It is not easy to measure and locate large plots of land. In addition, when measuring large plots, if multiple directions need to be measured, it is easy to produce angle deviations during measurement due to the lack of a structure that can display angles, resulting in irregular measured plots, further affecting the measurement effect. When the land space planning field measurement device measures highly irregular planes, due to the low height of the device, the straightness of the measuring ruler is easily affected by the terrain, thereby affecting the measurement results and causing inaccurate measurement values. In addition, the device is not equipped with a balancing structure, which may affect the measurement process due to balance problems. 2. The national land space planning field measurement device does not have a structure for calibrating the measurement position. The drilling structure in the structure needs to rotate the spiral auger deep underground, which will damage the ground at the measurement point, making it difficult to mark the location, and thus easily causing the measurement point to fail, affecting the subsequent national land space planning field measurement work.
