Description

Technical Field

[0001] The present invention belongs to the technical field of geospatial information surveying and mapping. Specifically, it particularly relates to a portable geospatial information surveying and mapping instrument for geospatial information collection. Background Art

[0002] Geospatial information is the various states of the earth's surface reflected in digital form for people to study, reference, and use as a basis for construction. Therefore, the accuracy of geospatial information data is of great importance. A portable geospatial information surveying and mapping instrument is a device that integrates multiple geospatial information collection technologies. It has the characteristics of portability, high precision, and multi-functionality. This device can collect, process, store, and transmit geospatial information data in real time, providing strong support for geospatial information processing, analysis, and application.

[0003] With the rapid development of technology, geospatial information technology, as an important tool for exploring the earth's surface features, environmental changes, and natural resource management, has become increasingly prominent. In scientific research and practical applications, in the face of complex and changeable geomorphologies, such as mountains, vast grasslands, and rugged deserts, it is often necessary for scientific research personnel to personally carry professional surveying and mapping instruments to the field for accurate measurement. In this process, it not only tests the professional skills and adaptability of scientific research personnel but also places extremely high requirements on the portability, durability, and reliability of surveying and mapping instruments. However, in actual operation, some precise and expensive surveying and mapping instruments, such as GPS receivers, total stations, and laser rangefinders, are extremely vulnerable to damage due to accidental dropping, bumping, or jolting during long-distance travel or when carried in complex terrains. This will not only lead to a decrease in measurement accuracy, affecting the accuracy and integrity of data, but may also delay project progress due to equipment failures, seriously reducing work efficiency and even increasing unnecessary economic burdens.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the attached drawings in the embodiments of the invention. Obviously, the described embodiments are only a part of the embodiments of the invention, rather than all the embodiments. Based on the embodiments of the invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the invention.

[0022] In the description of the present invention, it should be understood that the terms "open hole", "upper", "lower", "top", "middle", "inner", etc. indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0023] Please refer to Figures 1-6 As shown, the present invention is a portable geographic information surveying and mapping instrument for geographic information collection, including a surveying and mapping device 1. The surveying and mapping device 1 is arranged on a lifting plate 2. The lifting plate 2 is slidably connected inside a protection box 3. One end of a first threaded rod 4 is rotatably installed at the bottom of the lifting plate 2. The other end of the first threaded rod 4 is threadedly connected inside a threaded cylinder 5. The threaded cylinder 5 is fixedly installed with a first worm gear 6. The first worm gear 6 meshes with a first worm 7. One end of the first worm 7 is fixedly installed with the output shaft of a first motor 8. The other end of the first worm 7 is provided with a driving mechanism for controlling the sliding of a first cover plate 9 and a second cover plate 12. Both the first cover plate 9 and the second cover plate 12 are slidably connected to the protection box 3.

[0024] The working principle of a portable geographic information mapping instrument for geographic information collection proposed by the present invention is that when using this device, first start the first motor 8. The output shaft of the first motor 8 drives the first worm 7 to rotate, thereby driving the first worm gear 6 to rotate, and then driving the threaded barrel 5 to rotate, thereby driving the first threaded rod 4 to rise along the inside of the threaded barrel 5, and then driving the lifting plate 2 to rise, thereby driving the mapping device 1 to rise.

[0025] It should be noted that when the first motor 8 drives the first worm 7 to rotate, it synchronously drives the driving mechanism to move, thereby driving the first cover plate 9 and the second cover plate 12 to slide along the upper part of the protection box 3. Therefore, when the lifting plate 2 drives the mapping device 1 to rise, it will not be blocked.

[0026] Furthermore, when the mapping is completed, reverse-start the first motor 8, thereby driving the first worm 7 to rotate in the reverse direction, and then making the lifting plate 2 drive the mapping device 1 to descend until it is received inside the protection box 3. And at this time, the driving mechanism will also move in the reverse direction, so that the first cover plate 9 and the second cover plate 12 will slide simultaneously towards the central axis position of the protection box 3, thereby sealing the protection box 3, preventing external dust from falling in, and at the same time being able to protect the mapping device 1 to prevent it from being knocked during carrying, thereby causing damage.

[0027] In one embodiment, for the above-mentioned driving mechanism, the driving mechanism includes a first incomplete gear 10 arranged on the first worm 7. The first incomplete gear 10 is rotatably installed on the protection box 3. One end of a first connecting rod 11 is rotatably installed on the first incomplete gear 10, and the other end of the first connecting rod 11 is rotatably installed on the first cover plate 9. One end of a second connecting rod 13 is rotatably installed on the first cover plate 9, and the other end of the second connecting rod 13 is rotatably installed on the protection box 3.

[0028] In one embodiment, for the above-mentioned first incomplete gear 10, the first incomplete gear 10 meshes with a second incomplete gear 14.

[0029] The working principle of a portable geographic information mapping instrument for geographic information collection proposed by the present invention is that the output shaft of the first motor 8 drives the first worm 7 to rotate, thereby driving the first incomplete gear 10 to rotate, and then driving the first connecting rod 11 to rotate, thereby driving the first cover plate 9 to slide along the upper part of the protection box 3. And at this time, the second connecting rod 13 also rotates, starting to play a role in guiding and fixing the first cover plate 9.

[0030] It should be noted that while the first incomplete gear 10 rotates, it synchronously drives the second incomplete gear 14 to rotate, thereby driving the third connecting rod 15 to rotate, driving the second cover plate 12 to slide along the upper part of the protection box 3, and at this time, the fourth connecting rod 16 also rotates to start the fixed guiding effect on the second cover plate 12.

[0031] In one embodiment, for the above-mentioned surveying and mapping device 1, the surveying and mapping device 1 is fixedly installed on the lifting plate 2, the threaded cylinder 5 is rotatably installed inside the protection box 3, the first worm 7 is rotatably installed inside the protection box 3, and the first motor 8 is fixedly installed on the protection box 3.

[0033] The working principle of a portable geographic information surveying and mapping instrument for geographic information collection proposed by the present invention is that when the device is in use, the level 19 can be used to observe whether it is in a horizontal state, and by starting the second motor, the rotating disk 17 is driven to rotate, further driving the protection box 3 and the surveying and mapping device 1 to rotate, so that the surveying at different positions can be realized without moving the device.

[0034] In one embodiment, for the above-mentioned fixed disk 18, a fixed rod 20 is rotatably installed at the bottom of the fixed disk 18, a support rod 21 is slidably connected inside the fixed rod 20, a second threaded rod 22 is rotatably installed inside the fixed rod 20, and the second threaded rod 22 is fixedly installed with a second worm gear 23.

[0035] In one embodiment, for the above-mentioned second worm gear 23, the second worm gear 23 meshes with a second worm 24, and the second worm 24 is rotatably installed inside the fixed rod 20.

[0036] The working principle of a portable geographic information surveying and mapping instrument for geographic information collection proposed by the present invention is that when the overall height of the device needs to be adjusted, by rotating the second worm 24, the second worm gear 23 is driven to rotate, further driving the second threaded rod 22 to rotate, driving the support rod 21 to slide along the inside of the fixed rod 20, and thus realizing the adjustment of the overall height of the device.

[0037] It should be noted that the second worm 24 and the second worm gear 23 have self-locking properties, so the stability of the device can be ensured.

[0038] In one embodiment, for the above-mentioned fixed rod 20, one end of the fixed rod 20 is rotatably installed with a rod 25, and the other end of the rod 25 is rotatably installed on a connecting member 26, and the connecting member 26 is slidably connected to a guide rod 27.

[0040] The working principle of a portable geographic information surveying and mapping instrument for geographic information collection proposed by the present invention is that when the device needs to be stored, the operator only needs to rotate the bolt 29, then take out the bolt 29 from the inside of the hole 28, and then slide the connecting member 26 downward, thereby driving the rod 25 to rotate, and further driving the fixed rod 20 to gather toward the center position of the fixed disk 18 at the same time, so as to achieve contraction and facilitate carrying.
