Technical Field
[0001] The present invention mainly relates to the technical field of land surveying, and in particular to a field surveying device for land space planning. Background Art
[0002] In the field of national land space planning, field survey is the key link to obtain accurate geographic information and rationally plan land use. Accurate field survey data is of vital importance for formulating scientific and reasonable planning schemes, ensuring the effective use of land resources, and promoting regional sustainable development.
[0003] The existing Chinese patent with publication number CN 118189922 A discloses a field measurement device for land planning space, including a fixed component, a movable frame is provided on the left side of the fixed component, a card slot is provided at the top of the inner side of the movable frame, a guide slot is provided on the side of the movable frame away from the fixed component, an adaptive component is movably connected inside the guide slot, and an auxiliary support component is movably connected at the position of the adaptive component below the card slot. The present invention completes the adjustment process by making the adjustment rod always contact with different concave and convex terrains, and at this time, the movable frame can still maintain a constant height, avoiding the problem of measurement data deviation caused by the tilt of the measuring rope caused by the concave and convex terrain, and keeping the measuring rope parallel to the ground as much as possible during the measurement process, improving the measurement accuracy and reducing data deviation.
[0004] However, the land surveying device has the following defects when used in practice: When the measuring equipment in the prior art is in use, the measuring rope is prone to loosening or shaking during the process of retracting and releasing, which greatly affects the accuracy of the measurement.

[0020] Embodiment: A field measurement device for territorial spatial planning As Figure 1-7As shown in the figure, a field measurement device for territorial spatial planning, its specific structure includes: A base 10 and several support legs 101 fixed to its bottom. An installation frame 20 is fixedly arranged on the top surface of the base 10. A rotating shaft 201 is installed on the upper part of the installation frame 20 by bearings. A wire winding disc 202 is arranged inside the installation frame 20. The rotating shaft 201 horizontally penetrates through the center of the wire winding disc 202 and is fixedly connected to it. A measuring rope 203 is fixedly arranged on the wire winding disc 202. The measuring rope 203 is wound around the outside of the wire winding disc 202 for several weeks. A pressure regulating component 30 is arranged on one side of the base 10. The measuring rope 203 passes through the pressure regulating component 30. The above working principle: When this device is in use, the base 10 and the support legs 101 are used to stably place the measuring device. During measurement, place this device on the ground, pull out the measuring rope 203 for on-site measurement. By rotating the rotating shaft 201 to drive the wire winding disc 202 to rotate, the retraction and release of the measuring rope 203 are realized. This structural design makes the retraction and release operation of the measuring rope 203 simple and convenient. The cooperation of the installation frame 20, the rotating shaft 201 and the wire winding disc 202 can efficiently store and release the measuring rope 203, which is convenient for carrying and using. The support legs 101 enhance the stability of the device during on-site measurement and ensure the accuracy of measurement.
[0021] The pressure regulating component 30 includes: a support plate 301, and the support plate 301 is fixedly installed on one side of the base 10; a U-shaped frame 302, and the U-shaped frame 302 is fixedly installed on the top surface of the support plate 301. Limiting grooves 303 are respectively opened on the front and rear sides of the U-shaped frame 302; guide rails 304, and the guide rails 304 are respectively fixedly installed on the upper parts on both sides of the limiting grooves 303; sliders 305, and sliders 305 that are slidably matched with the corresponding guide rails 304 are respectively arranged in the limiting grooves 303; a guide wheel 306, and a guide wheel 306 is rotatably installed between the two sliders 305; a roller 307, and a liftable roller 307 is arranged below the guide wheel 306. The measuring rope 203 passes between the guide wheel 306 and the roller 307; limiting rods 308, and limiting rods 308 are respectively fixedly installed on the tops of the limiting grooves 303. The limiting rods 308 vertically penetrate through the corresponding sliders 305 and are slidably matched with the corresponding sliders 305. Anti-detachment baffles are fixedly installed at the lower ends of the limiting rods 308; springs 309, and springs 309 are respectively sleeved on the outside of the limiting rods 308. The springs 309 are located above the sliders 305 and always squeeze the sliders 305 downward. One end of the spring 309 is fixedly connected to the top surface of the limiting groove 303, and the other end of the spring 309 is fixedly connected to the top surface of the corresponding slider 305. The limiting rods 308 and the anti-detachment baffles can prevent the sliders 305 from detaching from the guide rails 304, ensuring the stability and reliability of the structure.
[0022] When the measuring rope 203 is pulled out or retracted, it will drive the guide wheel 306 to move up and down along the guide rail 304 under the action of the slider 305. The spring 309 always presses the slider 305 downward, so that the guide wheel 306 maintains a certain pressure on the measuring rope 203. The idler roller 307 can be lifted and lowered. The measuring rope 203 passes between the guide wheel 306 and the idler roller 307, and the guide wheel 306 and the idler roller 307 play a role in supporting and adjusting the pressure on the measuring rope 203. The pressure regulating assembly can automatically adapt to the movement of the measuring rope 203. Through the cooperation of the spring 309 and the slider 305, the guide wheel 306 always acts on the measuring rope 203 with an appropriate pressure, preventing the measuring rope 203 from becoming slack or shaking during the retracting and extending process, and improving the measurement accuracy.
[0023] Adjusting blocks 40 are respectively arranged below the sliders 305. The two ends of the idler roller 307 are respectively rotatably connected to the corresponding adjusting blocks 40. Vertical through screw holes 401 are respectively formed in the centers of the top surfaces of the adjusting blocks 40. Adjusting screws 402 are respectively installed in the screw holes 401 in a threaded fit manner. The adjusting screws 402 vertically penetrate through the support plate 301 and are rotatably connected thereto. The two adjusting screws 402 are in transmission connection. By rotating the adjusting screw 402, since the adjusting screw 402 is in threaded fit with the screw hole 401 on the adjusting block 40, the adjusting block 40 will move up and down as the adjusting screw 402 rotates, thereby driving the idler roller 307 to lift and lower, changing the distance between the idler roller 307 and the guide wheel 306 to adapt to measuring ropes 203 with different thicknesses or tension requirements. The two adjusting screws 402 are in transmission connection, which can ensure the synchronous lifting and lowering of both ends of the idler roller 307. The precise adjustment of the height of the idler roller 307 is realized, which can flexibly adapt to the working states of various measuring ropes 203, and improves the versatility and applicability of the device.
[0024] Synchronous wheels 403 are respectively fixedly installed on the outer parts of the two adjusting screws 402. The two synchronous wheels 403 are in transmission connection through a synchronous belt 404. When one of the adjusting screws 402 is rotated, the synchronous wheel 403 on this adjusting screw 402 will drive the other synchronous wheel 403 to rotate through the synchronous belt 404, so that the two adjusting screws 402 rotate synchronously, ensuring the consistency of the lifting and lowering of both ends of the idler roller 307, ensuring that both ends of the idler roller 307 remain horizontal when adjusting the height, further improving the accuracy and stability of the pressure adjustment of the measuring rope 203, and enhancing the measurement effect.
[0025] A handle 405 is fixedly installed at the lower end of one of the adjusting screws 402. The setting of the handle 405 provides an easy-to-apply-force component for the operator, greatly improving the operation convenience of adjusting the height of the idler roller 307, enabling the staff to complete the adjustment work more easily, and improving the work efficiency.
[0026] Four support legs 101 are fixedly installed at the four corners of the bottom surface of the base 10. Sliding sleeves 50 are installed in a sliding fit on the outside of the support legs 101. A connecting plate 501 is fixedly installed inside the sliding sleeves 50 together. A plurality of evenly distributed ground nails 502 are fixedly installed on the bottom surface of the connecting plate 501. The arrangement of the ground nails 502 enhances the fixing effect of the device on the ground, prevents the device from displacing during the measurement process, and improves the measurement accuracy. Extension plates 503 extending outside the base 10 are fixedly installed on both the front and rear sides of the connecting plate 501. Grips 504 are fixedly installed on the top surfaces of the extension plates 503. By holding the grips 504 and moving the connecting plate 501 up and down, the sliding sleeves 50 slide on the support legs 101, thereby adjusting the contact condition between the ground nails 502 and the ground. When the device needs to be fixed, move the connecting plate 501 downward to insert the ground nails 502 into the ground; when not needed, move the connecting plate 501 upward to retract the ground nails 502.
[0027] A through hole is opened on one side of the top surface of the base 10. A locking screw 60 is rotatably installed in the through hole. A nut sleeve 601 arranged opposite to the locking screw 60 is fixedly installed on one side of the top surface of the connecting plate 501. The locking screw 60 is inserted into the nut sleeve 601 and is in threaded fit with it. Rotate the locking screw 60 to make it in threaded fit with the nut sleeve 601. By tightening or loosening the locking screw 60, the connecting plate 501 can be fixed at the current position or the fixation can be released, which is convenient for adjusting the extending and retracting states of the ground nails 502.
[0028] An outer shell 70 is arranged outside the winding disc 202. The outer shell 70 is fixedly connected to the mounting frame 20. And a through slot 701 is opened on one side of the outer shell 70 facing the pressure regulating assembly 30. The measuring rope 203 passes through the through slot 701 and extends outside the outer shell 70. The outer shell 70 is used to protect the winding disc 202 to prevent it from being collided by the outside or interfered by sundries. The measuring rope 203 enters and exits the outer shell 70 through the through slot 701. When the winding disc 202 rotates, the measuring rope 203 can smoothly pass through the through slot 701 for retracting and releasing.
[0029] A crank 80 is fixedly installed at one end of the rotating shaft 201. An operator rotates the crank 80, and the crank 80 drives the rotating shaft 201 to rotate, thereby making the winding disc 202 rotate and realizing the quick retracting and releasing operation of the measuring rope 203.
