Description

Technical Field

[0001] This utility model relates to the field of surveying and positioning equipment technology, and more specifically, to a surveying and positioning device based on BeiDou navigation. Background Technology

[0002] The BeiDou Navigation Satellite System consists of three segments: space, ground, and user. It can provide high-precision, high-reliability positioning, navigation, and timing services to various users worldwide, 24 / 7, and has short message communication capabilities. It has initially achieved regional navigation, positioning, and timing capabilities, with positioning accuracy at the decimeter and centimeter level, velocity measurement accuracy of 0.2 m / s, and timing accuracy of 10 nanoseconds. Existing surveying instruments used for mapping usually have BeiDou navigation and positioning capabilities.

[0003] Commonly available Beidou navigation surveying and positioning devices typically use tripods to fix the surveying instrument in place. However, when adjusting the surveying instrument to different heights, all three legs of the tripod need to be adjusted, making the tripod adjustment process overly cumbersome. Furthermore, the tripod can only be used to face the surveying instrument in a fixed direction. When surveying in different directions, the tripod needs to be raised and the direction adjusted, which is inconvenient for fine-tuning the surveying direction and makes it difficult to use.

[0004] Therefore, we have made improvements to this and proposed a mapping and positioning device based on BeiDou navigation. Utility Model Content

A mounting plate 702 is mounted on the top of the limiting slider 701, and a connecting block 703 is mounted on the bottom of the mounting plate 702. An adjusting rod 704 is rotatably mounted on the connecting block 703. A longitudinal worm gear 705 is mounted on the side of the adjusting rod 704. The longitudinal worm gear 705 meshes with the longitudinal worm wheel 602. A longitudinal knob 706 is mounted on one end of the adjusting rod 704.

[0041] Implementation Process: Support member 101 serves as the basic support structure for the entire device. Three support legs 102 are rotatably connected to the periphery of support member 101, allowing for adjustment of the deployment angle according to terrain requirements. Foot pads 103 are rotatably fitted at the bottom of support legs 102, increasing friction with the ground and making the device more stable. Support legs 102 cooperate with height adjustment component 3 to adjust the overall height of the device. Threaded post 201 is installed on top of support member 101, achieving height adjustment through threaded engagement with height adjustment component 3. Fixing member 202 is installed on top of threaded post 201 to support lateral control component 4. When adjusting the overall height of the device, rotating threaded sleeve 301, due to its threaded engagement with threaded post 201, causes the threaded sleeve to... 301 moves up and down along the threaded post 201. The rotating disk 302 is movably connected in the groove on the side of the threaded sleeve 301. When the threaded sleeve 301 moves up and down, it drives the rotating disk 302 to move up and down. One end of the three limiting rods 303 is rotatably engaged with the rotating disk 302, and the other end is rotatably connected to the three support legs 102. When the rotating disk 302 moves up and down, it pushes or pulls the support legs 102 around the rotation point with the support member 101 through the limiting rods 303, thereby changing the angle between the support legs 102 and the ground, realizing the adjustment of the overall height of the device. When adjusting the lateral angle of the surveying and positioning instrument 8, the lateral knob 405 is rotated, which drives the control rod 404 to rotate. The lateral worm gear 406 on the side of the control rod 404 rotates accordingly. 401 is installed on top of the fixing component 202. The circular shell 402 is installed on top of the fixing base 401. The square plate 403 is located at the bottom of the inner cavity of the circular shell 402, providing rotational support for the control rod 404. The transverse worm gear 406 cooperates with the transverse adjustment component 5 to realize the control of the transverse adjustment component 5. When the transverse worm gear 406 rotates, it drives the transverse worm wheel 502 that meshes with it to rotate. Since the transverse worm wheel 502 is installed on the side of the rotating column 501, the rotating column 501 also rotates. The support plate 503 on the top of the rotating column 501 also rotates, realizing the angle adjustment of the surveying and positioning instrument 8 in the horizontal direction. The circular ring 504 is installed at the bottom of the support plate 503 and slides in the circular groove 407, which plays a role in limiting and stabilizing the support plate 503. When adjusting the longitudinal angle of the surveying and positioning instrument 8, rotating the longitudinal knob 706 causes the adjusting rod 704 to rotate, and the longitudinal worm 705 on the side of the adjusting rod 704 rotates accordingly. The longitudinal worm 705 meshes with the longitudinal worm wheel 602. When rotating, it causes the limiting slider 701 to slide in the limiting groove 604, restricting the mounting plate 702 to move only longitudinally. The connecting block 703 connects the mounting plate 702 and the adjusting rod 704, so that the rotation of the adjusting rod 704 is converted into the longitudinal movement of the mounting plate 702, thereby realizing the position adjustment of the surveying and positioning instrument 8 in the longitudinal direction. Through the coordinated adjustment of the above components, the surveying and positioning instrument 8 can be adjusted to a suitable height, horizontal angle and longitudinal position, thereby improving the accuracy of surveying and positioning work.

Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
