Description

Technical Field

[0001] The present invention relates to the technical field of positioning benchmarks, and specifically to a positioning benchmark for territorial spatial planning. Background Art

[0002] During the process of territorial spatial planning, it is usually necessary to measure and map the land. During the measurement process, it is necessary to insert a positioning benchmark directly into the soil layer, and use the positioning benchmark to assist in completing the surveying and mapping of the land.

[0003] In the Chinese patent with the patent publication number CN222318057U, a positioning benchmark for territorial spatial planning is disclosed, including: a benchmark main body that is hollow inside and has an open upper end. A sharp cone is connected to the lower end of the benchmark main body. A secondary benchmark is inserted into the benchmark main body. A circumferential array of clamping blocks is connected to the outside of the open upper end of the benchmark main body. Threads are provided on the outside of the clamping blocks. The clamping blocks have an inclination angle of one degree to two degrees from the lower end to the upper end. The inner diameter of the clamping blocks is the same as the outer diameter of the secondary benchmark. Four T-shaped chutes are arranged in an array at the lower end of the inner wall of the benchmark main body. A slider with the same cross-section as the chute is inserted into the chute. A threaded hole is provided in the middle of the slider. An installation plane is provided on the outside of the benchmark main body and on one side of the chute. A bolt is provided on the outside of the slider. The bolt is threadedly connected to the threaded hole provided in the middle of the slider. The length of the bolt is shorter than the thickness of the slider. An extension plate is connected to the lower end of the slider. A support bracket is rotatably connected to the end of the extension plate. By inserting the support bracket to the required depth into the ground and adjusting it to a suitable angle, and then tightening the bolt to fix it, the positioning benchmark for territorial spatial planning can be erected on the ground.

[0004] The above positioning benchmark strengthens the stability of the benchmark main body by setting the support bracket. Although it can achieve a certain strengthening effect, the overall structure still relies on the rod structure for auxiliary strengthening. Moreover, in environments such as wetlands, sandy lands or snow fields, the contact effect between the rod structure and the sandy soil is poor. Due to the fluidity of the sand, when the benchmark main body is inserted into the sandy land, the effect of strengthening stability through the support bracket is poor, resulting in the benchmark main body still having looseness and deviation. A loose benchmark or a benchmark with an inclined position is likely to cause deviation in the measurement results, ultimately leading to inaccurate measurement results and affecting the final accuracy of land measurement. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides a positioning benchmark for territorial spatial planning, which has the advantages of being applicable to multiple environments and having stable installation of the positioning benchmark in various environments.

[0016] Advantages of the present invention:

[0017] 1. For the positioning benchmark for territorial spatial planning, by controlling that the auxiliary support rod and the base can be set in an upward retracted state, a horizontal unfolded state, and a downward inserted state, it is convenient for the positioning benchmark to be used on hard paved ground, muddy ground, sandy land, wetland or snow land, thus effectively improving the use effect and scope of the positioning benchmark, facilitating land planning and measurement on multiple terrains, and further improving the convenience of land planning and measurement.

[0018] 2. For the positioning benchmark for territorial spatial planning, by controlling the side insertion rod to be inserted into the soft ground, and then inflating the connecting membranes on both sides through the inflation cavity to make the connecting membranes inflate and expand, using the inflated connecting membranes to squeeze the surrounding soft soil layer, thereby increasing the hardness of the ground around the side insertion rod, and forming multiple inflated fixed spaces in the areas of the multiple side insertion rods fixed to the bottom surface of the base. Through the multiple inflated fixed spaces, the installation stability of the positioning benchmark is further increased. The stably installed positioning benchmark can effectively avoid data deviation in land measurement caused by the shaking of the positioning benchmark, and ensure the stability and accuracy in the land measurement process through the stable positioning benchmark.

[0019] 3. The positioning benchmark for the territorial spatial planning can increase the bottom support area of the main rod body by controlling the side insertion rod to be in the unfolded state, reduce the overall center of gravity, and further increase the stability of the main rod body directly placed on the ground. As a result, the positioning benchmark can be used on the paved ground, ensuring its stable placement under conditions where it cannot be inserted. This facilitates the use of the positioning benchmark on the paved ground, guarantees the accuracy of using the calibration benchmark on the paved ground, and further ensures the accuracy of topographic measurement on the paved ground.

[0020] 4. For the positioning benchmark for the territorial spatial planning, by controlling the side insertion rod to be inserted downward and simultaneously controlling the driving gear to rotate, the driving gear drives the sleeve shaft to rotate through the external tooth ring, transmission gear, and driving shaft, causing the transmission extension rod to drive the auxiliary plug head to rotate. Since the auxiliary plug head is helically arranged, it inserts deep into the ground during rotation, thereby increasing the insertion depth of the side insertion rod, further enhancing the installation stability of the positioning benchmark, and further ensuring the stability and accuracy of land measurement.

Detailed implementation manners

[0035] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Embodiment 1, please refer to Figure 1 - Figure 11 , a positioning benchmark for territorial space planning, including a main rod body 1, the bottom of the main rod body 1 is movably connected with a support rod 2, the bottom of the support rod 2 is rotatably connected with a base 3, an auxiliary support rod 4 is arranged outside the base 3, the inside of the support rod 2 is threadedly connected with a main cutting rod 5, a radial limit is arranged between the main cutting rod 5 and the base 3; the state between the auxiliary support rod 4 and the base 3 includes an upward converging state, a horizontal unfolding state and a downward cutting state;

[0037] The auxiliary support rod 4 includes a connecting rod 41 and a side cutting rod 42 connected by hinge, the two sides of the side cutting rod 42 are provided with storage cavities 421, the inside of the storage cavity 421 is provided with a connecting membrane 463, and an inflation mechanism is arranged outside the connecting membrane 463.

[0038] It should be noted that this positioning benchmark is used for hard paved ground, muddy ground, sandy ground, wetland or snow ground.

[0039] Among them, the auxiliary support rod 4 is set in a horizontally extended state or a downward inserted state, which is suitable for directly placing the positioning benchmark on the ground or inserting it into the ground.

[0040] Furthermore, when the auxiliary support rod 4 is inserted into the ground with relatively soft geology such as sandy land, snow land or wet land, the connecting membrane 463 can be controlled to expand and inflate outward, so as to increase the acting force between the auxiliary support rod 4 and the ground, and then ensure the stable effect of the device on the relatively soft ground, thereby improving the placement stability of the positioning benchmark.

[0041] Reference Figure 1 、 Figure 2 and Figure 4 In an alternative embodiment, the support rod 2 is used to drive the main insertion rod 5 to move downward, and control the main insertion rod 5 to extend to the outside of the lower bottom surface of the base 3.

[0042] It should be noted that when inserting into the muddy ground, the main insertion rod 5 can be controlled to insert into the muddy ground, and through the cooperation of the main insertion rod 5 and the base 3, the stability of the main rod body 1 inserted into the ground can be ensured, and the overall operation is simple and the positioning is stable.

[0043] Reference Figure 2 、 Figure 5 and Figure 6 In an alternative embodiment, at least three groups of auxiliary support rods 4 are provided, and the three groups of auxiliary support rods 4 are evenly arranged in an array on the top edge side of the base 3. A fixed block 31 is fixedly connected to the top of the base 3, and the connecting rod 41 is rotatably connected to the fixed block 31. A limiting mechanism is arranged inside the auxiliary support rod 4, and the limiting mechanism is used to control the auxiliary support rod 4 to maintain an upward converging state, a horizontally extended state and a downward inserted state.

[0044] It should be noted that when the auxiliary support rod 4 is in the horizontally extended state, the bottom surface of the side insertion rod 42 is flush with the bottom surface of the base 3, and when the auxiliary support rod 4 is in the downward inserted state, the side insertion rod 42 and the base 3 are in a vertical state.

[0045] Among them, the limiting mechanism includes a first limiting rod 47 movably connected inside the connecting rod 41. A return spring 471 is arranged between the first limiting rod 47 and the connecting rod 41. A sealing column 472 is fixedly connected to the outside of the first limiting rod 47. An inclined guiding groove 473 is formed on the side of the sealing column 472. A fixed limiting hole 32 and a rod-receiving limiting hole 33 are formed on the outside of the fixed block 31. The first limiting rod 47 is used to be inserted into the fixed limiting hole 32 and the rod-receiving limiting hole 33 to keep the side inserting rod 42 in a retracted state and a horizontally unfolded state. A limiting driving rod 475 is rotatably connected inside the side inserting rod 42. A second limiting rod 474 is threadedly connected inside the limiting driving rod 475. A inserting limiting hole 411 and an unfolding limiting hole 412 are formed on the outside of the connecting rod 41. The second limiting rod 474 is used to be inserted into the inserting limiting hole 411 and the unfolding limiting hole 412 to keep the side inserting rod 42 in a horizontally unfolded state and a vertically inserting state.

[0046] It should be noted that during the adjustment of the auxiliary support rod 4, the limiting driving rod 475 is rotated, and the limiting driving rod 475 drives the second limiting rod 474 to move towards the connecting rod 41, so as to control the second limiting rod 474 to be inserted into the inserting limiting hole 411 or the unfolding limiting hole 412 respectively.

[0047] Specifically, when the auxiliary support rod 4 is in a retracted state, by rotating the limiting driving rod 475, the second limiting rod 474 is controlled to be inserted into the unfolding limiting hole 412. At the same time, the second limiting rod 474 pushes the first limiting rod 47 inside the unfolding limiting hole 412 to control the first limiting rod 47 to be inserted into the rod-receiving limiting hole 33.

[0048] By controlling the first limiting rod 47 to be inserted into the rod-receiving limiting hole 33 and the second limiting rod 474 to be inserted into the unfolding limiting hole 412, it is ensured that the auxiliary support rod 4 is in a retracted state (refer to Figure 2 ), and the retracted state of the auxiliary support rod 4 is effectively ensured to be stable.

[0049] Furthermore, when controlling the auxiliary support rod 4 to be unfolded, similarly, the second limiting rod 474 can be controlled to be inserted into the unfolding limiting hole 412, and the first limiting rod 47 is inserted into the fixed limiting hole 32. At this time, the side inserting rod 42 is in a horizontally unfolded state (refer to Figure 10 ). By controlling the first limiting rod 47 to be inserted into the unfolding limiting hole 412 and the first limiting rod 47 to be inserted into the fixed limiting hole 32, the stability of the unfolded state of the side inserting rod 42 is ensured.

[0050] By controlling the side cutting rod 42 to be in the deployed state, the bottom support area of the main rod body 1 is increased, the overall center of gravity is lowered, and the stability of the main rod body 1 placed directly on the ground is increased, so that the positioning benchmark can be used on the paved ground, and the placement stability of the positioning benchmark can be ensured under the condition that cutting cannot be carried out, so as to facilitate the use of the positioning benchmark on the paved ground, ensure the accuracy of using the calibration benchmark on the paved ground, and further ensure the accuracy of terrain measurement on the paved ground.

[0051] Reference Figure 7 and Figure 9 , further, when the auxiliary support rod 4 is controlled to be in the cutting state, similarly, the second limiting rod 474 can be controlled to be inserted into the cutting limiting hole 411. The second limiting rod 474 is inserted into the inclined guiding groove 473, and the second limiting rod 474 pushes the first limiting rod 47 to be inserted into the fixed limiting hole 32 through the inclined guiding groove 473. At this time, the side cutting rod 42 is in the downward cutting state (reference Figure 11 ), by controlling the second limiting rod 474 to be inserted into the cutting limiting hole 411 and the first limiting rod 47 to be inserted into the fixed limiting hole 32, the stability of the side cutting rod 42 during cutting is ensured.

[0052] By controlling the auxiliary support rod 4 and the base 3 to be able to be set in an upward converging state, a horizontal deployed state and a downward cutting state, it is convenient for the positioning benchmark to be used on hard paved ground, muddy ground, sandy ground, wetland or snow, so as to effectively improve the use effect and scope of the positioning benchmark, facilitate land planning measurement of multiple terrains, and further improve the convenience of land planning measurement.

[0053] Embodiment 2, further on the basis of Embodiment 1, a driving shaft 44 is rotatably connected inside the side cutting rod 42. A sleeve shaft 441 is fixedly connected to the end of the driving shaft 44. A transmission extension rod 45 is slidably connected with radial limitation inside the sleeve shaft 441. The outer end of the transmission extension rod 45 extends to the side cutting rod 42. An auxiliary plug head 43 is fixedly connected to the outer end of the transmission extension rod 45. A transmission gear 442 is fixedly connected to the outside of the driving shaft 44. An external gear ring 6 is rotatably connected to the outside of the base 3. When the auxiliary support rod 4 is in the cutting state, the transmission gear 442 and the external gear ring 6 are in meshed connection. A driving gear 61 is meshed with the outside of the external gear ring 6. The driving gear 61 is installed on the top of the base 3.

[0054] It should be noted that, based on the first embodiment, when the control side insertion rod 42 is in the downward insertion state, the driving gear 61 can be controlled to rotate. The driving gear 61 drives the outer tooth ring 6 to rotate, the outer tooth ring 6 drives the transmission gear 442 to rotate, the transmission gear 442 drives the sleeve shaft 441 to rotate through the driving shaft 44, the sleeve shaft 441 drives the transmission extension rod 45 to rotate, and the transmission extension rod 45 drives the auxiliary plug head 43 to rotate. The auxiliary plug head 43 is spirally arranged and inserts deep into the ground during rotation, thereby further increasing the installation stability of the positioning benchmark.

[0055] Embodiment 3. Refer to Figure 8 , further based on the second embodiment, two threaded segments with opposite thread directions are provided on the outer part of the driving shaft 44. Threaded sliders 46 are symmetrically threadedly connected to the outer parts of the two threaded segments. An outer support rod 461 is hinged to the outer part of the threaded slider 46, and a positioning rod 462 is hinged to the outer part of the outer support rod 461. When the positioning rod 462 is in the retracted state, it seals the storage cavity 421. Both sides of the connecting membrane 463 are respectively connected to the bottom of the cavity of the storage cavity 421 and the positioning rod 462.

[0056] It should be noted that when the traditional positioning benchmark is inserted into relatively soft ground such as wetlands, sandy lands, and snow lands, due to the relatively soft overall ground medium, when the traditional positioning benchmark is directly inserted into the ground, the contact between the transmission positioning benchmark and the ground is single, so the positioning benchmark is prone to tilt or fall under the action of wind or its own gravity.

[0057] When the positioning benchmark of the present invention is inserted into the bottom surface of a relatively soft medium, based on the second embodiment, when the driving shaft 44 is controlled to rotate, the driving shaft 44 drives the threaded sliders 46 to move towards each other. The threaded sliders 46 push the positioning rods 462 to slide towards the outer sides of the side insertion rod 42 through the outer support rods 461. The two positioning rods 462 on both sides synchronously drive the connecting membrane 463 to move towards the outer sides of the side insertion rod 42, thereby achieving the effect of assisting in stabilizing the side insertion rod 42, increasing the contact effect and contact connection viscosity between the side insertion rod 42 and the soft ground, effectively avoiding the possibility of the positioning benchmark tilting or falling during the installation process, and further ensuring the installation stability of the positioning benchmark.

[0058] Refer to Figure 7 , in an alternative embodiment, the inflation mechanism includes an air guide cavity 48 opened inside the connecting rod 41, a connecting air passage 482 opened inside the side insertion rod 42, and an inflation cavity 483 opened inside the side insertion rod 42. The inflation cavity 483 communicates with the connecting membrane 463 and is used to inflate the inside of the connecting membrane 463.

[0059] Among them, an inflation nozzle 481 is provided outside the air guide cavity 48. The first limiting rod 47 is installed inside the air guide cavity 48. The cutting limiting hole 411 and the unfolding limiting hole 412 are both communicated with the air guide cavity 48. The second limiting rod 474 is in sealed plug connection with both the cutting limiting hole 411 and the unfolding limiting hole 412. Through holes are provided inside both the first limiting rod 47 and the second limiting rod 474. The air guide cavity 48 is communicated with the connecting air duct 482 through the through holes of the first limiting rod 47 and the second limiting rod 474. A connecting air hole is provided inside the driving shaft 44. The connecting air duct 482 is communicated with the inflation cavity 483 through the connecting air hole of the driving shaft 44.

[0060] It should be noted that when the cutting work of the side cutting rod 42 is completed and the positioning rod 462 is controlled to move outward and expand, the stability of the installation of the base 3 and the main rod body 1 on the ground is further enhanced through the positioning rod 462 and the connecting film 463.

[0061] It should be noted that the sealing column 472 abuts against the outside of the cutting limiting hole 411. When the sealing column 472 rotates 90°, when the inclined guide groove 473 is misaligned with the cutting limiting hole 411, the sealing column 472 plays the role of sealing the cutting limiting hole 411. When the inclined guide groove 473 of the sealing column 472 overlaps with the cutting limiting hole 411, the cutting limiting hole 411 is communicated with the air guide cavity 48 through the inclined guide groove 473 and the first limiting rod 47.

[0062] Furthermore, an inflation device, including a syringe or an air pump, can be used to inflate the inside of the air guide cavity 48 through the inflation nozzle 481 by means of the syringe or the air pump. The gas sequentially passes through the air guide cavity 48, the first limiting rod 47, the second limiting rod 474, the connecting air duct 482 and the driving shaft 44 and enters the inflation cavity 483. Finally, the two-side connecting films 463 are inflated through the inflation cavity 483, so that the connecting films 463 are inflated and expanded. The expanded connecting films 463 are used to squeeze the surrounding soft soil layer, thereby increasing the hardness of the ground around the side cutting rod 42, and multiple expanded fixed spaces are formed in the areas of the multiple side cutting rods 42 fixed on the bottom surface of the base 3. Through the multiple expanded fixed spaces, the installation stability of the positioning benchmark is further increased. The stably installed positioning benchmark can effectively avoid data deviation in land measurement caused by the shaking of the positioning benchmark, and ensure the stability and accuracy in the land measurement process through the stable positioning benchmark.

[0063] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
