Description

Technical Field

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

[0002] National land space planning serves as a guide for national spatial development, a spatial blueprint for sustainable development, and the fundamental basis for all types of development, protection, and construction activities. Establishing a national land space planning system and supervising its implementation will integrate spatial planning, including major functional area planning, land use planning, and urban and rural planning, into a unified national land space plan, achieving "multiple plans in one." This will strengthen the guiding and constraining role of national land space planning on various special plans. National land space planning requires extensive field surveying to obtain sufficient information on the distribution of land before conducting spatial planning.

[0003] Land surveying is the process of measuring and mapping the quantity, distribution, and topographic characteristics of various types of land using surveying and remote sensing techniques. This includes topographic surveying, cadastral surveying, land leveling surveying, current land use status surveying, and investigation of reserve resources such as barren hills and wastelands. Surveying methods include geodesy, conventional surveying, aerial photogrammetry, remote sensing, and map compilation. With the gradual completion of the national basic topographic map, land surveying primarily refers to various aspects beyond topographic surveying, all conducted 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, comprising a mounting frame, support structures mounted on both sides of the mounting frame, a lifting structure mounted on the mounting frame, and a drilling structure mounted on the lifting structure; the drilling structure comprises a lifting frame, a turntable rotatably mounted on the lifting frame, and a spiral auger mounted on the turntable; the supporting structure comprises two opposing support rods, an adjustment rod rotatably mounted in the middle of the support rods, a limit rod mounted on the outer side of the support frame between the two support rods, a sliding sleeve slidably mounted on the limit rod, and the sliding sleeves are respectively connected to the adjustment rods on both sides; a spring is mounted on the limit rod, and the two ends of the spring are respectively connected to the sliding sleeve and the first support plate. This device can assist the operator in land surveying and positioning, fix the device in a certain position through the drilling structure and further perform measurement activities, and improve stability during use and flexibility during movement by providing a lifting structure and rollers.

[0005] However, the field measurement device for national land space planning has the following defects when used:

[0006] 1. When using a soft ruler or tape measure to measure, the device requires that one end of the ruler be placed on a fixed point before moving it to the next measuring point. This makes it difficult to measure and locate large plots of land. Furthermore, when measuring large plots in multiple directions, the device lacks a structure that can display angles, which can easily lead to angle deviations during measurement. This can cause irregularities in the plot, further impacting the measurement results. Furthermore, when measuring highly irregular surfaces, the device is relatively low, which can easily affect the straightness of the ruler due to the terrain, further impacting the measurement results and leading to inaccurate measurements. Furthermore, the device lacks a balancing structure, which can affect the measurement process due to balance issues.

[0007] 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 into the ground, 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.

The outer surface of the two ends of the movable cone rod 407 is densely provided with handle patterns 409, which are used for personnel to facilitate the movement of the movable cone rod 407. The conical rod 407 rotates so that it can be threadedly matched with the internal thread 406 provided inside the lifting tube 401, so that the movable conical rod 407 can be extended from the inside of the lifting tube 401. End covers 4010 are provided at both ends of the lifting tube 401 and inserted into the inside of the lifting tube 401. The end covers 4010 are located in the inner part of the lifting tube 401 and are fixed with threaded strips 4011 on the outer periphery. The threaded strips 4011 can be threadedly matched with the internal thread 406. By providing the end covers 4010, the movable conical rod 407 is prevented from moving out of the lifting tube 401 when in the storage state, thereby improving the storage degree of the device.

[0049] In this embodiment, the lifting tube 401 is provided through the support tube 101 and can be freely lifted and lowered, so that the lifting tube 401 can be used simultaneously when the support tube 101 is fixed in the forward or reverse direction. Furthermore, the damping traction column 402 is provided in the handle tube 103, and the traction belt 404 connected to the traction block 403 connected to the side of the lifting tube 401 is provided at both ends of the damping traction column 402. By moving the damping traction column 402, the lifting tube 401 is driven The support tube 101 is lifted and lowered, and the movable cone rod 407 is set inside the support tube 101, and the inner thread 406 is set at the middle of the movable cone rod 407 and at both ends of the inner side of the lifting tube 401. By rotating the movable cone rod 407, the outer thread 408 provided on the outer periphery of the movable cone rod 407 can be threadedly matched with the inner thread provided at both ends of the inner side of the lifting tube, and then fixed to the upper end or lower end of the lifting tube 401 and the extension length can be adjusted by rotation, so that the movable cone rod 407 can be moved upward or downward in the device. The ground can be marked when the lifting tube 401 is in use. The end caps 4010 that can cooperate with the internal threads 406 are further provided at both ends of the lifting tube 401 to prevent the movable cone rod 407 in the lifting tube 401 from extending due to gravity when not in use. When in use, the end caps 4010 installed in the extending direction of the movable cone rod 407 are first rotated and removed, and the movable cone rod 407 is further rotated to make the external threads 408 provided on its outer circumference threadedly cooperate with the internal threads 406 so that it is fixed and extended to a certain length, which is convenient for marking. The damping traction column 402 is further moved to pull the traction belt 404 to drive the lifting tube 401 to descend, thereby driving the movable cone rod 407 to descend and insert into the ground to mark the ground position, or the ground position can be marked by other marking methods such as paint marking, object marking, etc. Further, the marked position can be further marked by installing devices such as marking stakes to facilitate subsequent work. Through this structure, the effect of marking and positioning in both the upper and lower directions can be achieved through a set of marking and positioning devices, which is convenient for use.
