Description

Technical Field

[0001] The utility model relates to the technical field of surveying and mapping, in particular to a surveying and mapping laser device carried by an unmanned aerial vehicle (UAV). Background Art

[0002] Surveying and mapping refers to the science and technology of measuring, recording, and mapping the positions, shapes, sizes, mutual relationships, and attributes of surface, underground, and spatial objects. It covers fields such as map making, spatial data acquisition and processing, and the application of geographic information systems (GIS). The development of surveying and mapping technologies enables humans to more accurately understand and utilize the Earth's surface and other spatial information.

[0003] Traditional surveying and mapping devices need to move on the ground. Therefore, there are significant limitations for complex terrains (such as mountainous areas, forests, rivers, etc., which are difficult to traverse) or harsh environments (such as desert or polar regions), making it difficult to achieve complete coverage and accurate surveying and mapping. UAVs can conduct surveying and mapping in rugged terrains or other inaccessible areas, such as high mountains, forests, swamps, etc. They can quickly fly over large areas and conduct continuous surveying and mapping, covering a wider area than traditional hand-held or ground-mounted laser scanners.

[0004] However, existing UAVs generate various types of vibrations during flight, including mechanical vibrations from rotors or propellers, aerodynamic vibrations, and attitude vibrations caused by flight attitude adjustments. These vibrations are directly transmitted to the laser surveying and mapping equipment mounted on the UAV, affecting the measurement accuracy and stability. The mechanical installation structure of the laser surveying and mapping device may not be suitable for direct connection to the UAV body, making it impossible to achieve a quick connection between the laser surveying and mapping device and the UAV body, and ensuring stable surveying and mapping conditions when the surveying and mapping device follows in flight. The present utility model specifically proposes a surveying and mapping laser device carried by an unmanned aerial vehicle to solve the problems mentioned in the above background art.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0024] Referring to Figures 1-4 , a mapping laser device based on a drone includes an unmanned aircraft body 1 and a laser mapping device body 2. A mounting seat 3 is fixedly installed on the lower center of the unmanned aircraft body 1. A telescopic column 5 is fixedly installed at the center of the lower side of the mounting seat 3. The telescopic column 5 includes a sleeve and a sliding column. The sliding column slides inside and outside the sleeve, and a strong spring corresponding to the sliding column is arranged inside the sleeve. The laser mapping device body 2 is located below the mounting seat 3. The sliding column of the telescopic column 5 is fixedly provided with an installation sleeve 12 at the lower end, and an installation insertion cylinder 14 corresponding to the installation sleeve 12 is fixedly installed on the upper side of the laser mapping device body 2. The laser mapping device body 2 is inserted into the installation sleeve 12 through the upper installation insertion cylinder 14, so that the laser mapping device body 2 is installed on the unmanned aircraft body 1;

[0025] Furthermore, a plurality of triangular brackets 4 are arranged between the laser surveying and mapping device body 2 and the mounting seat 3, a plurality of card seats 13 are fixed on the peripheral side of the mounting sleeve 12, the lower ends of the plurality of triangular brackets 4 are rotatably connected with the corresponding card seats 13, a plurality of sockets corresponding to the card seats 13 are fixed on the peripheral side of the mounting insert 14, limiting grooves 15 corresponding to the sockets are provided on the peripheral side of the mounting sleeve 12, a plurality of card heads are fixed on one side of the card seat 13, and through grooves corresponding to the card heads are provided in the sockets, a limiting block 6 is fixed to the inner center of the mounting sleeve 12, and a rectangular groove 16 corresponding to the limiting block 6 is provided at the upper center of the mounting insert 14. When the installation insert tube 14 device enters the installation sleeve 12, the inner square groove 16 of the installation insert tube 14 corresponds to the fixed limit block 6. At this time, the card seat 13 on the side of the installation insert tube 14 can also enter the installation sleeve 12 through the limit groove 15 until the installation insert tube 14 completely enters the sleeve. The installation insert tube 14 in the sleeve can be rotated to one side, and the square groove 16 is misaligned with the limit block 6, so that the installation insert tube 14 is locked in the sleeve. After the installation insert tube 14 is rotated at an angle, several card heads on the card seat 13 enter the through grooves inside the socket, further improving the connection between the installation insert tube 14 and the installation sleeve 12;

[0026] Furthermore, the upper end of the triangular bracket 4 is rotatably connected with a sliding piece 7, and the sliding piece 7 is translated and slid on the lower side of the mounting seat 3 of the mounting seat 3. A rotating rod 10 connected to the mounting seat 3 is arranged on one side of the plurality of sliding pieces 7. The lower side of the mounting seat 3 is rotatably connected with an end face gear ring 8 located outside the mounting seat 3.

A limited block 11 is fixed at the outer end of the rotating rod 10, and a plurality of limit grooves corresponding to the limit block 11 are opened on one side of the sliding piece 7. When the drone body 1 needs to be mounted below When the height of the laser surveying and mapping device body 2 is adjusted, the drone body 1 can be directly pushed up, the strong spring inside the telescopic column 5 is compressed, and the plurality of triangular brackets 4 are rotated at an angle, and the sliding sheet 7 connected thereto is pressed and moved outward, and the upper limit block 2 11 of the rotating rod 10 cooperates with the limit groove to fix the adjusted position immediately. When the upper and lower positions need to be adjusted back, the end face gear ring 8 on the mounting seat 3 is rotated, and through the linkage of the plurality of face gears 9, the rotating rod 10 drives the connected limit block 2 11 to disengage from the limit groove, and then the laser surveying and mapping device body 2 at the lower end of the telescopic column 5 can be adjusted back.
