[0002] Land surveying refers to the process of using computer technology, optoelectronic technology, network communication technology, space science, and information science as a foundation, and global positioning system, remote sensing, and geographic information system as the core technologies, to obtain graphic and location information reflecting the current state of the ground by measuring existing feature points and boundaries, for use in engineering construction planning and design and administrative management.

[0003] During land surveying, the surveying instrument is supported by a platform on a tripod. However, the area of ​​land to be measured is often large, requiring the tripod and surveying instrument to be moved. The size of the surveying instrument results in a high weight at the end of the tripod, making it prone to tilting during transport. When the platform is disconnected from the surveying instrument, the connection structure on the platform makes disassembly and reassembly of the surveying instrument inconvenient. After the surveying instrument is removed from the platform, the lens is not protected, which means that the surveying instrument may be subject to collisions during transport, making it difficult to protect the lens.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-5 A portable land surveying device includes a surveying instrument 1 and a tripod 2 for support. A platform 3 for placing the surveying instrument 1 is installed on the tripod 2. The tripod 2 is placed on the ground so that it can support the surveying instrument 1. The surveying instrument 1 can measure the land. This technical solution is prior art and will not be described in detail here.

[0023] A frame 5 is installed on the platform 3. The frame 5 and the positioning plate 4 extend to the upper part of the platform 3. The frame 5 is a U-shaped structure with an opening on one side. The frame 5 is equipped with a handrail, and the positioning plate 4 extending into the platform 3 is integrally connected to the bottom of the frame 5. The surveying instrument 1 is located inside the frame 5. By placing the surveying instrument 1 inside the frame 5, the frame 5 can surround the surveying instrument 1 from the outside. The handrail can be used to move the frame 5 and the surveying instrument 1 quickly, making it more convenient to carry the surveying instrument 1.

[0024] A clamping structure for clamping the positioning plate 4 is installed on platform 3.

[0025] The clamp structure includes a pressure rod 6 movably mounted on the platform 3 and extending into the positioning plate 4. A movable rod 7 is slidably sleeved inside the platform 3, and a slider 8 extending into the pressure rod 6 is fixedly mounted on the movable rod 7. A movable plate 9 is fixedly mounted on the movable rod 7. The platform 3 guides the movable rod 7, so that the movable rod 7 can smoothly pull the movable plate 9 when moving. By pulling out the movable rod 7, the movable rod 7 drives the slider 8 to slide in the guide groove when moving. The slider 8 drives the pressure rod 6 to deflect around the pin point. When deflecting, the pressure rod 6 can extend into the groove 11 in the positioning plate 4.

[0026] A contact rod 10 is fixedly installed on the positioning plate 4 to abut against the movable plate 9. A displacement plate 12 is slidably sleeved inside the positioning plate 4, and a spring 13 is welded between the displacement plate 12 and the positioning plate 4. A positioning rod 14 is fixedly installed on the displacement plate 12, penetrating the positioning plate 4 and extending into the pressure rod 6. By moving the displacement plate 12 downward, the positioning rod 14 penetrates the positioning plate 4 and extends into the pressure rod 6, thereby connecting the positioning plate 4 and the platform 3, and making the positioning plate 4 easier to disassemble and assemble later.

[0027] The end of the pressure rod 6 away from the slider 8 is connected to the pin of the platform 3. The positioning plate 4 has a groove 11 corresponding to the pressure rod 6. The pressure rod 6 has a guide groove for guiding the slider 8. The spring 13 is vertically welded to the upper end of the moving plate 9 extending into the positioning plate 4. The displacement plate 12 has a positioning groove corresponding to the pressure rod 6. The spring 13 resets the displacement plate 12. When the displacement plate 12 is unloaded, the spring 13 can drive the displacement plate 12 and the positioning rod 14 back to the initial position.

[0028] A protective component for protecting the surveying instrument 1 is installed on the frame 5.

[0029] The protective assembly includes an intercepting rod 15 movably mounted on the frame 5 and corresponding to the surveying instrument 1. A second spring 16 is welded between the intercepting rod 15 and the frame 5. A sealing cover 17 extending to the intercepting rod 15 is mounted on the frame 5. The end of the intercepting rod 15 away from the sealing cover 17 is connected to the frame 5 by a pin. The sealing cover 17 has a concave structure, and the sealing cover 17 and the intercepting rod 15 are provided with magnets 18 that attract each other. The second spring 16 guides the intercepting rod 15. When the intercepting rod 15 is unloaded, the second spring 16 can drive the intercepting rod 15 to intercept the surveying instrument 1, and the sealing cover 17 protects the lens on the surveying instrument 1 from the front, so that the lens can be protected from impact when the surveying instrument 1 is transported.

[0030] The functional principle of this utility model can be explained through the following operation methods:

[0031] After surveying the land, the surveying instrument 1 needs to be moved.

[0032] The displacement plate 12 is lifted, causing the displacement plate 12 to drive the positioning rod 14 to disconnect from the positioning groove on the pressure rod 6. The spring 13 is then subjected to force, causing the pressure rod 6 to disconnect from the positioning plate 4.

[0033] Manually press the moving rod 7 to make the moving rod 7 drive the slider 8 to slide in the guide groove. The moving rod 7 drives the slider 8 to press the pressure rod 6, causing the pressure rod 6 to deflect around the pin point as the fulcrum. The pressure rod 6 is disconnected from the groove 11 on the positioning plate 4.

[0034] Remove the positioning plate 4, causing the positioning plate 4 to disconnect the frame 5, the surveying instrument 1, and the platform 3.

[0035] Pressing the sealing cover 17 causes the opposite poles of the magnetic block 18 to attract each other, causing the sealing cover 17 to extend onto the intercepting rod 15, thus sealing the surveying instrument 1. The frame 5 and the positioning plate 4 are moved upward by the handrail, allowing the operator to move the surveying instrument 1.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
