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

[0047] The technical solution of the present application is described in detail below with reference to the accompanying drawings.

[0048] Example 1

[0049] like Figures 1 to 11As shown, this embodiment provides a geographic information surveying and mapping system 100, including a surveying instrument 1, a mounting bracket 2 and an auxiliary mounting member 3. The surveying instrument 1 is used for geographic information surveying and mapping. The mounting bracket 2 includes a base 21 and a tripod 22, the surveying instrument 1 is mounted on the top surface of the base 21, and the tripod 22 is mounted on the bottom surface of the base 21 and is used to be telescopically supported on the ground. The auxiliary mounting member 3 includes a first driving member 31, a mounting tube 32, a battery 33, a second driving member 34, a rotating screw 35, a moving slider 36 and at least three legs 37. The first driving member 31 is mounted on the base 21, and the output end of the first driving member 31 is connected to the mounting tube 32 for driving the mounting tube 32 to rotate. The mounting tube 32 includes a coaxially connected main body portion 321, an insertion portion 322 and a guide block 323; a first accommodating cavity 3211 is formed in the main body portion 321, and the battery 33, the second driving member 34 and the rotating screw 35 are sequentially arranged in the first accommodating cavity 3211 from top to bottom. The battery 33 is electrically connected to the first driving member 31 and the second driving member 34 respectively. The output end of the second driving member 34 is connected to the rotating screw 35 for driving the rotating screw 35 to rotate. The moving slider 36 is sleeved on the rotating screw 35 and form a screw nut pair with the rotating screw 35, at least three legs 37 are evenly spaced along the circumference of the rotating screw 35 and are rotatably connected to the moving slider 36; the insertion part 322 is formed into a conical structure, the large end of the insertion part 322 is connected to the main body part 321, the large end of the insertion part 322 is recessed inward to form a second accommodating cavity 3221 that is interconnected with the first accommodating cavity 3211, and a through hole 3222 corresponding to the legs 37 is opened on the side of the insertion part 322, the angle between the extension direction of the through hole 3222 and the axial direction of the installation cylinder 32 is an acute angle, the guide block 323 is installed in the second accommodating cavity 3221, and a wedge surface 3231 corresponding to the leg 37 is formed on the guide block 323, so that the leg 37 can be guided by the wedge surface 3231.

[0050] The auxiliary mounting member 3 includes a ground insertion state and a stabilization state. In the ground insertion state, the first driving member 31 drives the mounting tube 32 to rotate so as to insert the mounting tube 32 into the ground, and the support leg 37 is located in the first accommodating chamber 3211 and / or the second accommodating chamber 3221; in the stabilization state, the second driving member 34 drives the rotating screw 35 to rotate so that the support leg 37 is close to the guide block 323 and can penetrate into the through hole 3222 and partially pass out of the through hole 3222 under the guidance of the wedge surface 3231.

[0051] Through the above technical scheme, the geographic information surveying and mapping system 100 of the present application can be installed more quickly, stably and reliably in slippery and icy field surveying locations through the auxiliary mounting parts 3, and can be well adapted to slippery application scenarios in the field, which is not only conducive to ensuring the accuracy of surveying and mapping, but also conducive to improving surveying and mapping efficiency.

[0052] To facilitate understanding by relevant technical personnel, the working principle / working process of the above technical solution is explained below.

[0053] When surveying is required in the field where the ground is slippery, icy or other harsh surveying and mapping environments, the entire geographic information surveying and mapping system 100 can be installed at the surveying and mapping location using the provided auxiliary mounting member 3. Specifically, the first driving member 31 is first started, and the first driving member 31 will drive the entire mounting tube 32 to rotate. The operator can then hold the mounting bracket 2 (or the surveying and mapping instrument 1) and conveniently insert the rotating mounting tube 32 into the icy or slippery ground. The tripod 22 is then adjusted so that the tripod 22 is unfolded and supported on the ground, so that the posture of the entire geographic information surveying and mapping system 100 is convenient for surveying and mapping. The second driving member 34 can be started, and the second driving member 34 drives the rotating screw 35 to rotate, and the moving slider 36 sleeved on the rotating screw 35 will move toward the guide block 323. After the leg 37 contacts the wedge surface 3231 on the guide block 323, the leg 37 will penetrate into the through hole 3222 under the guidance of the wedge surface 3231 and emerge from the through hole 3222. Since the entire (or most) insertion part 322 is located below the ground at this time, the extended leg 37 will extend into the soil layer around the insertion part 322, so that the entire installation tube 32 can be reliably and stably installed at the surveying and mapping site. In this way, not only can the surveying and mapping instrument 1 be installed in a slippery outdoor environment more quickly and conveniently, thereby effectively improving the surveying and mapping efficiency, but also the installation stability of the surveying and mapping instrument 1 can be effectively guaranteed, and the problems of shaking and vibration of the surveying and mapping instrument 1 during the surveying and mapping process can be avoided, thereby effectively improving the accuracy of the surveying and mapping data.

[0054] In the above technical solution, it should be noted that, first, the installation of the surveying instrument 1 of the present application at the surveying site is achieved by relying on the tripod 22 and the auxiliary mounting member 3. Among them, for the tripod 22, the tripod 22 plays the role of assisting in improving stability and assisting in bearing the weight of the surveying instrument 1. For the auxiliary mounting member 3, during installation, the auxiliary mounting member 3 is inserted into the soil layer first, which can play a certain installation guide role. At the same time, it is also convenient for the operator to accurately determine the installation position of the surveying instrument 1 (the installation cylinder 32 can be directly inserted into the soil layer position corresponding to the key surveying points such as control points, reference points, guide points, and triangulation points). In addition, the auxiliary mounting member 3 can also form a reliable grip through the legs 37. That is to say, the auxiliary mounting member 3 can not only play the role of installation guidance and facilitate rapid installation, but also help to accurately control the installation position of the surveying instrument 1. At the same time, it can also effectively ensure the installation stability of the surveying instrument 1.

[0055] Second, the first accommodating cavity 3211 formed in the mounting tube 32 can accommodate the battery 33, and the battery 33 is arranged at the top of the first accommodating cavity 3211. In this way, the arranged battery 33 can more conveniently form an electrical connection with the first driving member 31 and the second driving member 34 to power them. At the same time, the battery 33 can be replaced more quickly without affecting other parts of the auxiliary mounting member 3 (for example, a battery 33 replacement port is set on the top or side of the mounting tube 32).

[0056] Third, in actual use, when the use environment is an icy ground, in order to facilitate the insertion of the support leg 37 into the surrounding soil layer, the insertion part 322 can be inserted below the ice layer, so that the support leg 37 can be inserted into the surrounding soil layer, thereby improving the stability of the entire geographic information surveying and mapping system 100.

[0057] In one embodiment of the present application, Figure 3 and Figure 4 As shown, the mounting tube 32 of the present application may further include a partition plate 324, which is disposed in the first accommodating cavity 3211 and divides the first accommodating cavity 3211 into a first cavity 3211a and a second cavity 3211b arranged along the up and down directions, the first cavity 3211a being close to the base 21, the battery 33 being installed in the first cavity 3211a, and the second driving member 34 being located in the second cavity 3211b and being installed on the partition plate 324.

[0058] In this way, the partition plate 324 can divide the first accommodating cavity 3211 into a relatively independent first cavity 3211a and a second cavity 3211b, which can not only prevent small debris and foreign objects from entering the second cavity 3211b and interfering with the normal operation of the rotating screw 35 and the movable slider 36 when replacing the battery 33 located in the first cavity 3211a, but also effectively ensure the safety of the battery 33.

[0059] In one embodiment of the present application, Figure 5 and Figure 6 As shown, the movable slider 36 of the present application may include a slider body 361 and a plurality of anti-rotation strips 362. The shape of the slider body 361 is adapted to the first accommodating cavity 3211. The slider body 361 is sleeved on the rotating screw 35 and forms a screw-nut pair with the rotating screw 35. The side of the slider body 361 away from the second driving member 34 is recessed inward to form a notch 3611 corresponding to the support leg 37. The support leg 37 is rotatably installed in the notch 3611. A plurality of anti-rotation strips 362 are arranged on the side of the slider body 361 at intervals along the circumference of the slider body 361, and each anti-rotation strip 362 extends along the axial direction of the slider body 361. A plurality of anti-rotation cavities (not shown) extending in the same direction as the first accommodating cavity 3211 are formed in the first accommodating cavity 3211, and the anti-rotation cavity is used to accommodate the anti-rotation strips 362.

[0060] Thus, on one hand, the anti-rotation strip 362 and the anti-rotation cavity thus provided can ensure that the movable slider 36 moves up and down stably and reliably along the direction of the first accommodating cavity 3211 under the drive of the rotating screw 35, and prevent the movable slider 36 from shaking or rotating, thereby affecting the normal deployment of the legs 37. On the other hand, the notch 3611 formed on the slider body 361 can not only reliably install the legs 37 and ensure the smooth rotation of the legs 37, but also help to reduce the weight and manufacturing cost of the slider body 361.

[0061] In one embodiment of the present application, Figure 5 As shown, the guide block 323 of the present application can be formed into a conical structure, the large end of the guide block 323 is connected to the insertion part 322 and the small end of the guide block 323 points to the main body part 321, and the large end edge of the guide block 323 is smoothly connected to the through hole 3222.

[0062] In this way, the guide block 323 of the conical structure can not only guide the legs 37 contacting it at any angle to enter the through hole 3222 to achieve the operational reliability and fault tolerance of the present application, but also, compared with guide blocks 323 of other shapes, can effectively simplify the structural complexity of the guide block 323, avoiding the need to open a corresponding wedge surface 3231 on the guide block 323 for each leg 37. (For example, when the guide block 323 is set to a prism shape, it is necessary to open a wedge surface 3231 corresponding to each leg 37 at the corresponding position of the prism according to the number and position of the legs 37. In this way, not only is the structure more complex, but also the processing difficulty is high)

[0063] In one embodiment of the present application, Figure 5 and Figure 6 As shown, the support leg 37 of the present application may include a connecting portion 371 and a blocking portion 372 that are interconnected, wherein one end of the connecting portion 371 away from the blocking portion 372 is rotatably connected to the movable slider 36, and the shape of the blocking portion 372 is adapted to the through hole 3222; wherein, in the ground-inserted state, the blocking portion 372 is located in the through hole 3222 to block the through hole 3222.

[0064] In this way, when inserted into the ground, the blocking portion 372 of the leg 37 can block the through hole 3222, which can effectively prevent soil or other debris from entering the second accommodating chamber 3221 through the through hole 3222. Moreover, the inclined through hole 3222 and the guide block 323 can also effectively increase the difficulty of soil or other debris entering the second accommodating chamber 3221. Even if some soil or other debris enters the second accommodating chamber 3221, it is easy to fall out of the second accommodating chamber 3221 under the inclined guidance of the through hole 3222 and the guide block 323 and the pushing action of the leg 37.

[0065] It is understandable that, in order to facilitate the connection portion 371 of the leg 37 to smoothly enter and pass through the through hole 3222 during the rotation process, the cross-sectional size of the connection portion 371 can be set to be smaller than the cross-sectional size of the through hole 3222. For example, the connection portion 371 can be set to a cylindrical structure or a prismatic structure with a smaller cross-sectional size. The present application does not specifically limit the size and shape of the connection portion 371.

[0066] In one embodiment of the present application, Figure 1 and Figure 7 As shown, the geographic information surveying and mapping system 100 of the present application may further include a telescopic adjustment rod 4, which is disposed between the base 21 and the first driving member 31, and the two ends of the telescopic adjustment rod 4 are detachably connected to the base 21 and the first driving member 31 respectively.

[0067] Thus, on one hand, the telescopic adjustment rod 4 can reliably adjust the height of the surveying instrument 1 relative to the mounting tube 32 (that is, the height relative to the ground), so that it can be adapted to the requirements of different surveying heights, making the geographic information surveying and mapping system 100 of the present application have better environmental versatility. On the other hand, since the two ends of the telescopic adjustment rod 4 are detachably connected to the base 21 and the first driving member 31, respectively, in ordinary scenes (that is, non-slippery outdoor scenes, scenes where stable installation can be achieved through the tripod 22), the auxiliary mounting member 3 and the telescopic adjustment rod 4 can be disassembled, which is more convenient for surveying and mapping operations.

[0068] In the actual engineering experience of the inventor, since the user generally uses one eye to observe through the surveying instrument when surveying, the user's face is not completely aligned with the surveying instrument, and there is a certain misalignment, that is, when surveying, part of the user's face protrudes from the side of the surveying instrument. When surveying in a slippery outdoor environment, it is often accompanied by relatively bad air conditions such as dust and sand. The part of the user's face protruding from the side of the surveying instrument will be exposed to the above-mentioned bad air conditions for a long time. Although the face can be covered by wearing protective equipment such as headgear and covering face scarves, these protective equipment have a large cover on the user's face, which is not convenient for using eyes for surveying operations.

[0069] In view of this, in one embodiment of the present application, Figure 1As shown, the surveying and mapping instrument 1 of the present application may include a surveying and mapping body 11, a gripping bar 12 and two shielding components 13. The surveying and mapping body 11 is used for geographic information surveying and mapping. The gripping bar 12 is arranged on the surveying and mapping body 11 and is used for the user to hold; the gripping bar 12 includes a cover body 121 and a shell 122. The top surface of the shell 122 is recessed inward to form a receiving cavity 123. The cover body 121 is detachably covered on the shell 122; the two shielding components 13 are arranged side by side in the receiving cavity 123, and each shielding component 13 includes a shielding bar 131, a flexible shielding sheet 132 and a vertical rod 133. The shielding bars 131 corresponding to the two shielding components 13 are rotatably connected to the two ends of the shell 122, respectively, and the vertical rod 133 includes a connecting end 1331 and a movable end 1332 arranged opposite to each other. One side is connected to the shielding strip 131 and the flexible shielding sheet 132 extends in the same direction as the shielding strip 131, and the middle part of the other side of the flexible shielding sheet 132 is connected to the connecting end 1331; the shielding component 13 includes a storage state and a shielding state. In the storage state, the shielding strips 131 and the vertical rods 133 corresponding to the two shielding components 13 are all stored in the accommodating cavity 123, and the flexible shielding sheets 132 corresponding to the two shielding components 13 are folded and stored in the accommodating cavity 123; in the shielding state, the two shielding strips 131 corresponding to the two shielding components 13 are respectively rotated out of the accommodating cavity 123 and are located on both sides of the surveying and mapping body 11, and the shielding strip 131 extends in the vertical direction, and the movable end 1332 of the vertical rod 133 vertically presses against the middle part of the shielding strip 131 to enable the flexible shielding sheet 132 to be unfolded on the side of the surveying and mapping body 11.

[0070] In this way, on one hand, the gripping bar 12 can be used as a gripping part. When installation is required, it is convenient for the user to grip the gripping bar 12 and insert the installation tube 32 into the soil layer of the surveying and mapping site. When transportation is required, it is convenient for the operator to transport the geographic information surveying and mapping system 100 through the gripping bar 12. On the other hand, the shielding component 13 provided can be unfolded on the side of the surveying and mapping body 11 to shield the exposed part of the user's face, so that the user does not need to wear protective equipment that affects the surveying and mapping. It can not only effectively improve the user's experience, protect the user's face, and avoid the user's face from being directly exposed to adverse air conditions, but also make the user not need to wear protective equipment that affects the surveying and mapping, thereby improving the convenience and accuracy of the surveying and mapping operation.

[0071] In this embodiment, it should be noted that when the flexible shielding sheet 132 is stored, the flexible shielding sheet 132 can be folded and stored in the accommodating cavity 123 by utilizing the deformable property of the flexible shielding sheet 132 itself. When the flexible shielding sheet 132 needs to be unfolded, the vertical pole 133 and the shielding strip 131 are used as the unfolding skeleton to unfold the flexible shielding sheet 132 more stably on the side of the surveying and mapping body 11.

[0072] It is understandable that the flexible shielding sheet 132 of the present application can adopt a variety of optional implementations. For example, it can be set as a flexible sheet structure such as a cloth sheet, a plastic sheet, etc. The present application does not specifically limit the material of the flexible shielding sheet 132.

[0073] In one embodiment of the present application, Fig.10 As shown, the flexible shielding sheet 132 of the present application can be set as a semicircular sheet structure, the straight edge corresponding to the semicircular sheet structure is connected to the shielding strip 131, and the middle of the curved edge corresponding to the semicircular sheet structure is connected to the connecting end 1331.

[0074] In this way, the flexible shielding sheet 132 thus provided can be stably and reliably unfolded by the shielding strips 131 and the uprights 133 thus provided, so as to effectively resist the adverse air conditions and protect the exposed facial area of ​​the user.

[0075] In one embodiment of the present application, Figure 1 , Figure 7 and Figure 8 As shown, the shielding assembly 13 of the present application may also include a fastening rod 14 and a fastening nut 15. The fastening rod 14 is set as an L-shaped rod body structure. The fastening rod 14 includes a mounting rod body 141 and a connecting rod body 142 that are connected to each other. The end of the mounting rod body 141 away from the connecting rod body 142 is connected to the base 21, and the end of the connecting rod body 142 away from the mounting rod body 141 extends in a direction away from the surveying and mapping body 11, and a threaded section matching the fastening nut 15 is formed on the connecting rod body 142; a connecting through hole 1311 matching the connecting rod body 142 is formed on the shielding bar 131; in the shielding state, the connecting rod body 142 is inserted into the connecting through hole 1311, and the connecting rod body 142 is connected to the shielding bar 131 through the fastening nut 15 and the connecting rod body 142.

[0076] In this way, by means of the fastening rod 14 and the fastening nut 15 thus arranged, the shielding assembly 13 can be reliably and stably maintained in the shielding state, so as to improve the structural stability and reliability of the shielding assembly 13 under adverse air conditions.

[0077] In one embodiment of the present application, Fig.10 and Fig.11 As shown, the middle part of the shielding strip 131 of the present application may be formed with a mounting hole 1312 for the vertical rod 133 to be inserted; in the shielding state, the vertical rod 133 is inserted into the mounting hole 1312. In this way, not only can the shielding assembly 13 quickly and conveniently reach the shielding state and effectively maintain its structural stability, but it is also convenient to quickly and conveniently release the connection state between the vertical rod 133 and the shielding strip 131, so that the shielding assembly 13 can quickly and conveniently switch between the storage state and the shielding state.

[0078] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto, and any changes or substitutions within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
