[0002] The geographical environment field surveying and mapping device is a device used to measure, collect and map information such as topography, landforms, spatial position and its attributes in the natural geographical environment, so as to achieve accurate measurement and recording of geographical environment information. Among them, the surveying instrument is a high-tech measuring instrument integrating optics, mechanics and electronics. It can simultaneously measure angles, distances and automatically calculate and display measurement data such as coordinates. It has the characteristics of high precision, high efficiency and high automation. In geological surveying projects, the surveying instrument is the most commonly used equipment in digital mapping technology equipment.

[0003] After searching, the invention patent with Chinese patent number CN114838712A discloses a fixed-point surveying and mapping device for engineering surveying and mapping;

[0004] Compared with the prior art, the invention patent with Chinese patent number CN114838712A is provided with a supporting device, which can be adjusted in height as needed, and a rotatable limit seat is provided at the bottom of the supporting leg, which can adapt to unstable terrain, facilitate the balance of the bracket, and increase safety. An adjusting rod is provided at the bottom of the base, which can make fine height adjustments to the bottom tube to improve accuracy. By providing a connecting column and a bearing on the placement seat, the placement seat can be rotated at an angle as needed and fixed by a positioning bolt, without the need for angle adjustment of the overall bracket, and the fixing plate in the placement slot can fix the surveying instrument, thereby improving stability, which not only improves work efficiency but also increases the accuracy of surveying and mapping.

[0005] However, in actual use of the above device, when the sharp end of the supporting component is inserted into the ground for support, if soft soil is encountered, it is easy for the supporting component to sink into the soil, thereby causing the surveying and mapping instrument to tilt due to uneven force, affecting the stability and accuracy of the surveying and mapping process, and multiple supporting components need to be manually adjusted repeatedly when they are retracted and extended, resulting in low work efficiency. Therefore, a geographical environment field surveying and mapping device is proposed. Summary of the invention

[0006] The purpose of the present invention is to solve the shortcomings of the prior art that the supporting components sink into the soil, causing the surveying instrument to tilt, and multiple supporting components need to be manually adjusted repeatedly when they are retracted and extended, and to propose a geographical environment field surveying device.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Embodiment 1

[0034] like Figure 1-Figure 9As shown, a geographical environment field surveying and mapping device proposed by the present invention comprises a support seat 1 and a surveying and mapping instrument 2, wherein the surveying and mapping instrument 2 is mounted on the upper part of the support seat 1, and a plurality of third movable blocks 3 are rotatably connected to the outer side of the support seat 1, and an end of the third movable block 3 away from the support seat 1 is movably connected to a support rod 9, and a limiting assembly is arranged on the support rod 9, and the limiting assembly comprises a movable ring 27, a limiting ring 18 and a first movable block 21 arranged on the support rod 9, and a round rod 22 is mounted on the side of the support seat 1 away from the surveying and mapping instrument 2, and a plurality of extrusion rods 23 are mounted on the outer side of the round rod 22, and a retracting and extending assembly for the support rod 9 is jointly arranged on the extrusion rod 23 and the round rod 22, and the retracting and extending assembly comprises a U-shaped rod 25 on the extrusion rod 23, and a second movable block 31 arranged on the inner side of the U-shaped rod 25 and a rotating ring 33 arranged on the round rod 22;

[0035] A connecting rod 4 is installed at one end of the third movable block 3 away from the support seat 1, a movable rod 6 is slidably arranged on the inner side of the connecting rod 4, a first spring 5 is installed at one end of the movable rod 6 away from the support rod 9, an end of the first spring 5 away from the movable rod 6 is fixedly connected to the inner side of the connecting rod 4, a torsion spring 7 is installed at the side of the movable rod 6 away from the first spring 5, a side of the torsion spring 7 away from the movable rod 6 is fixedly connected to the support rod 9, a rotating rod 8 is installed at the side of the movable rod 6 close to the support rod 9, and a side of the rotating rod 8 away from the movable rod 6 is rotatably connected to the support rod 9;

[0036] A fixing block 12 is installed on the outer side of the support rod 9, a first sliding groove 10 is provided on the outer side of the connecting rod 4, a plurality of fixing grooves 11 are provided on the outer side of the connecting rod 4, the plurality of fixing grooves 11 are evenly distributed vertically, and the fixing grooves 11 and the first sliding groove 10 are connected, a second sliding groove 13 is provided on the outer side of the support rod 9, a sliding block 14 is slidably provided on the inner side of the second sliding groove 13, a second spring 15 is installed on the side of the sliding block 14 close to the limiting ring 18, a side of the second spring 15 away from the sliding block 14 is fixedly connected to the inner side of the second sliding groove 13, a movable ring 27 is installed on the side of the sliding block 14, and a second spring 15 is installed on the side of the L-shaped rod 17 close to the round rod 22;

[0037] An L-shaped rod 17 is installed at the bottom of the movable ring 27, and the end of the L-shaped rod 17 away from the movable ring 27 is fixedly connected to the limiting ring 18. A plurality of first square grooves 19 are opened on the inner side of the limiting ring 18, and a third spring 20 is installed on the inner side of the first square groove 19. The end of the third spring 20 close to the support rod 9 is fixedly connected to the first movable block 21, and the first movable block 21 is slidably connected to the first square groove 19. The size of the opening of the first square groove 19 is adapted to the size of the first movable block 21. The number of the first movable blocks 21 is multiple groups and is evenly distributed in a circle around the support rod 9, and the first movable block 21 is always kept in fit with the support rod 9 through the third spring 20.

[0038] In this embodiment, when the surveying and mapping instrument 2 needs to be supported by the support seat 1 to perform surveying and mapping work, after the connecting rod 4 is unfolded, the supporting rod 9 can be rotated, and the torsion spring 7 can be contracted at the same time, and the fixing block 12 can be driven to move to the outside of the fixing groove 11 until the fixing block 12 moves to the inside of the first sliding groove 10, and then the supporting rod 9 is pulled away from the supporting seat 1 by sliding the movable rod 6 on the inside of the connecting rod 4. At this time, the first spring 5 is stretched. When the distance between the supporting rod 9 and the supporting seat 1 moves to a suitable position, the supporting rod 9 can be slowly loosened at this time, and the torsion spring 7 in the contracted state is reset. When the support rod 9 is reset, the first sliding groove 10 on the support rod 9 is moved to the inner side of the fixed groove 11 at the corresponding position, thereby locking the adjusted support rod 9, repeating the operation, adjusting multiple support rods 9 to suitable positions for support use, and then supporting through the support rod 9. When supporting through the support rod 9, the support rod 9 can be restricted by the restriction ring 18 at this time to limit the sharp end of the support rod 9 inserted into the soil, thereby preventing one side of the support rod 9 from excessively sinking into the soil due to soft soil, thereby preventing the surveying and mapping instrument 2 from tilting due to uneven force, which ensures the stability and accuracy of the surveying and mapping process;

[0039] When the support rod 9 is stored, the fixed block 12 can be pushed to the outside of the fixed groove 11, and then moved to the inside of the first sliding groove 10. At this time, the first spring 5 in the stretched state is quickly reset, and at the same time drives the support rod 9 to reset, so that the support rod 9 is quickly retracted, and then the support rod 9 is rotated in the direction of the round rod 22 by the third movable block 3 until the end of the extrusion rod 23 squeezes the extrusion block 16, and the force generated by the extrusion rod 23 squeezing the extrusion block 16 causes the movable ring 27 to pass through the sliding block 14 along the second sliding groove 1 3 slides in the direction away from the support seat 1, and at the same time, the second spring 15 contracts until the movable ring 27 drives the limiting ring 18 to move to the end of the support rod 9, so that the sharp end of the support rod 9 is inside the limiting ring 18, so that the limiting ring 18 automatically covers the sharp end of the support rod 9 to prevent it from scratching people or damaging other equipment. This improves the safety of the measuring device during transportation and storage, and can also reduce the direct contact between the sharp end of the support rod 9 and the ground or other objects to a certain extent, thereby reducing wear and avoiding multiple support rods 9 of different lengths;

[0040] And when the limiting ring 18 moves, the first movable block 21 is driven to keep in contact with the support rod 9 by the force of the expansion and contraction of the third spring 20. Therefore, when the limiting ring 18 moves, the force of the third spring 20 to reset can ensure that the first movable block 21 is in contact with the support rod 9 while moving, thereby breaking up the soil on the end of the support rod 9, preventing the soil from clumping and hardening, and increasing the support length of the support rod 9, causing the support seat 1 to tilt when multiple support rods 9 are used for support.

[0041] Embodiment 2

[0042] like Figure 1-Figure 9 As shown, based on the first embodiment, a square rod 24 is installed on the upper part of the extrusion rod 23, and a U-shaped rod 25 is installed on the end of the square rod 24 away from the extrusion rod 23. A second square groove 29 is opened on the inner side of the U-shaped rod 25, and a fifth spring 30 is installed on the inner side of the second square groove 29. The fifth spring 30 is fixedly connected to the second movable block 31, and a connecting rope 32 is installed on the side of the second movable block 31 close to the fifth spring 30. The number of connecting ropes 32 is multiple groups and is evenly distributed around the round rod 22 in a circular shape. A rotating ring 33 is rotatably connected to the outer side of the round rod 22, and one end of the multiple connecting ropes 32 away from the second movable block 31 is fixedly connected to the rotating ring 33. A fourth spring 26 is installed on the inner side of the U-shaped rod 25, and a pressure plate 28 is installed on the end of the fourth spring 26 close to the second movable block 31, and the pressure plate 28 is slidably connected to the U-shaped rod 25, and the extrusion rod 23 is on the movement trajectory of the extrusion block 16.

[0043] In this embodiment, when the support rod 9 moves in the direction of the round rod 22, the support rod 9 moves to the inner side of the U-shaped rod 25, first squeezing the inclined surface of the second movable block 31, thereby driving the fifth spring 30 to contract through the force generated by squeezing the second movable block 31. At this time, the second movable block 31 is located on the inner side of the second square groove 29. When the support rod 9 moves to the other side of the second movable block 31, the pressure plate 28 is squeezed, thereby driving the fourth spring 26 to contract. At the same time, when the second movable block 31 is no longer squeezed by the support rod 9, the fifth spring 30 in the contracted state is reset, and at the same time drives the second movable block 31 to reset, and the support rod 9 is reset through the second movable block 31, and The pressure plate 28 can be pressed against the support rod 9 by the restoring force of the fourth spring 26, so that it is fixed more stably. When the support rod 9 needs to be unfolded for support, the rotating ring 33 can be rotated at this time, and the multiple connecting ropes 32 can be moved at the same time by the rotating ring 33, thereby driving the second movable block 31 to move to the inner side of the second square groove 29. At this time, the second movable block 31 no longer fixes the support rod 9, and the fourth spring 26 in the contracted state is reset, thereby popping out and unfolding the support rod 9 through the pressure plate 28, so that the surveying and mapping personnel can quickly complete the arrangement and withdrawal of the support rod 9, thereby improving work efficiency, eliminating the need for cumbersome adjustments, shortening preparation time, and enabling surveying and mapping work to be carried out faster.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
