[0003] With the widespread application of UAV aerial surveying technology, the demand for high-precision ground control points has surged, driving the innovation and development of aerial surveying ground control point coordinate identification structures.

[0004] Most coordinate marking structures on the market are equipped with protective shells, but these shells are manually disassembled, making the devices impractical. Therefore, a new type of coordinate marking structure for aerial surveying control points is needed. Utility Model Content

[0005] The purpose of this invention is to provide a coordinate marking structure for aerial survey image control points, which solves the problem that most existing coordinate marking structures are equipped with protective shells, and these protective shells are manually disassembled and reassembled, making the device impractical.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an aerial survey image control point coordinate marking structure, including a support frame, a first threaded groove at the bottom end of the support frame, a threaded rivet on the inner side of the first threaded groove, a second threaded groove on the upper surface of the support frame, a threaded base on the inner side of the second threaded groove, a sign above the threaded base, a placement groove on one side of the second threaded groove, a coordinate marking plate on the inner side of the placement groove, a hand grip groove on the upper surface of the coordinate marking plate, and a reflector above the coordinate marking plate;

A first rotating shaft is provided at the rotating end of the drive motor, and a sector bevel gear is fixed to the other end of the first rotating shaft. A first bevel gear is meshed with one side of the sector bevel gear, and a connecting column is fixed inside the first bevel gear.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The aerial survey image control point coordinate marking structure is equipped with a first bevel gear and a second bevel gear. By turning on the drive motor, the sector bevel gear can be driven to rotate. The rotation of the sector bevel gear can cause the first bevel gear to rotate. Similarly, the rotation of the sector bevel gear can cause the second bevel gear to rotate in the opposite direction. Thus, one rotation of the sector bevel gear can cause the connecting column to rotate back and forth once, which can drive the protective shell to open or close automatically. This avoids the problem that most coordinate marking structures are equipped with protective shells, which are manually disassembled and assembled, making the device impractical.

[0017] 2. The aerial survey image control point coordinate marking structure is equipped with a locking plate and a locking groove. By pushing the push plate with external force, the locking plate can be moved, allowing for quick disassembly of the coordinate marking plate. Conversely, the locking plate and locking groove can be locked and fixed by the locking structure. The damper and spring settings allow the locking plate to automatically return to its original position after the force is released, locking and fixing the coordinate marking plate. This allows for quick disassembly and assembly of the coordinate marking plate, facilitating maintenance or replacement of information on the coordinate marking plate and increasing its practicality.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, an aerial survey image control point coordinate marking structure includes a support frame 1. The bottom end of the support frame 1 is provided with a first threaded groove 2. A threaded rivet 3 is provided on the inner side of the first threaded groove 2. The upper surface of the support frame 1 is provided with a second threaded groove 4. A threaded base 5 is provided on the inner side of the second threaded groove 4. A sign 6 is provided above the threaded base 5. A placement groove 7 is provided on one side of the second threaded groove 4. A coordinate marking plate 8 is provided on the inner side of the placement groove 7. A hand grip groove 9 is provided on the upper surface of the coordinate marking plate 8. A reflector 10 is provided above the coordinate marking plate 8.

[0026] A hollow plate 11 is fixed to one side of the support frame 1. A drive motor 12 is fixed inside the hollow plate 11. A first rotating shaft 13 is provided at the rotating end of the drive motor 12. A sector bevel gear 14 is fixed to the other end of the first rotating shaft 13. A first bevel gear 15 is meshed with one side of the sector bevel gear 14. A connecting column 16 is fixed inside the first bevel gear 15. A second bevel gear 17 is meshed with the other side of the sector bevel gear 14. A bearing 18 is provided at the connection between the connecting column 16 and the hollow plate 11. A rotating plate 19 is fixed to the other end of the connecting column 16. A protective shell 20 is fixed to the side wall of the rotating plate 19.

[0027] It should be noted that the outer tooth block of the sector bevel gear 14 is not a complete circle. Therefore, when the side with the tooth block meshes with the first bevel gear 15 or the second bevel gear 17 respectively, it will drive the first bevel gear 15 to rotate in the forward direction or the second bevel gear 17 to rotate in the reverse direction. This enables the same connecting column 16 to rotate in both directions under different meshing conditions, thereby enabling the opening or closing of the protective shell 20.

[0028] The threaded rivet 3 forms a detachable structure with the support frame 1 through the first threaded groove 2, and the threaded rivet 3 is provided with four sets symmetrically distributed about the center line of the support frame 1. The support frame 1 can be installed through the threaded rivet 3 and the first threaded groove 2.

[0029] The threaded base 5 forms a detachable structure with the support frame 1 through the second threaded groove 4, and the threaded base 5 forms a fixed structure with the sign 6. The support frame 1 forms a locking structure with the coordinate marking plate 8 through the placement groove 7. The setting of the threaded base 5 and the second threaded groove 4 makes it easy to install and remove the sign 6.

[0030] The sector bevel gear 14 and the first rotating shaft 13 form a rotating structure through the operation of the drive motor 12. The sector bevel gear 14 and the first bevel gear 15 form a meshing structure, and the sector bevel gear 14 and the second bevel gear 17 form a meshing structure. When the drive motor 12 is turned on, the sector bevel gear 14 can be driven to rotate. Through the meshing structure of the sector bevel gear 14 and the first bevel gear 15, the rotation of the sector bevel gear 14 can cause the first bevel gear 15 to rotate. Since the outer tooth block of the sector bevel gear 14 is not a full circle, when one side with the tooth block rotates to the end of the second bevel gear 17 for meshing, the rotation of the sector bevel gear 14 can cause the second bevel gear 17 to rotate in the opposite direction. Thus, one rotation of the sector bevel gear 14 can cause the connecting column 16 to rotate back and forth once, which can drive the protective shell 20 to open or close automatically.

[0031] The first bevel gear 15 forms a fixed structure with the second bevel gear 17 through the connecting column 16, and the connecting column 16 forms a rotating structure with the hollow plate 11 through the bearing 18, and the connecting column 16 forms a fixed structure with the protective shell 20 through the rotating plate 19.

[0032] Example 2

[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment further illustrates Example 1. The support frame 1 has a slide rail 21 inside, a slider 22 is provided on the inner side of the slide rail 21, a push plate 23 is fixed on the side wall of the slider 22, a damper 24 is provided on one side of the push plate 23, a spring 25 is provided on the periphery of the damper 24, a locking plate 26 is fixed on the other side wall of the push plate 23, a locking groove 27 is provided on the outer side of the locking plate 26, and the locking groove 27 is opened on the side wall of the coordinate marking plate 8.

[0034] The push plate 23 forms a sliding structure with the slide rail 21 via the slider 22, and the push plate 23 forms an elastic structure with the support frame 1 via the damper 24 and the spring 25, and the push plate 23 forms a fixed structure with the locking plate 26.

[0035] The locking plate 26 forms a locking structure with the coordinate marking plate 8 through the locking groove 27. The locking groove 27 is provided with two sets of symmetrically distributed about the center line of the coordinate marking plate 8. By pushing the push plate 23 with external force, the locking plate 26 can be moved, so that the coordinate marking plate 8 can be quickly disassembled. Conversely, the locking structure of the locking plate 26 and the locking groove 27 can lock and fix the coordinate marking plate 8. The damper 24 and the spring 25 can make the locking plate 26 automatically return to its original position after the force is lost, locking and fixing the coordinate marking plate 8. This allows for quick disassembly and assembly of the coordinate marking plate 8, which is convenient for maintenance or replacement of the coordinate marking plate 8.

[0036] Working principle: First, the operator needs to install the support frame 1 using the threaded rivets 3 and the first threaded groove 2. Turning on the drive motor 12 rotates the sector bevel gear 14, which in turn rotates the first bevel gear 15. Similarly, the rotation of the sector bevel gear 14 causes the second bevel gear 17 to rotate in the opposite direction. One rotation of the sector bevel gear 14 causes the connecting column 16 to rotate back and forth once, thus automatically opening or closing the protective shell 20. Then, by pushing the push plate 23 with external force, the locking plate 26 can be moved, allowing for quick disassembly of the coordinate marking plate 8. Conversely, the locking structure of the locking plate 26 and the locking groove 27 secures the coordinate marking plate 8. The damper 24 and spring 25 ensure that the locking plate 26 automatically returns to its original position after the force is released, securing the coordinate marking plate 8. This allows for quick disassembly and assembly of the coordinate marking plate 8, facilitating maintenance or content replacement.
