Description

Technical Field

[0001] The utility model relates to the technical field of aerial survey marking guidance, in particular to a marking guidance device used for aerial survey. Background Art

[0002] Aerial surveying is also called aerial photogrammetry. Aerial photogrammetry refers to the process of taking continuous images of the ground with aerial photographic instruments on an airplane, and drawing a topographic map by combining ground control point measurement, adjustment and stereo mapping. Aerial photography is the process of taking pictures of the ground with a special camera mounted on an airplane or other aircraft (such as balloons, satellites and spacecraft). Aerial photography is the process of taking pictures of the ground with an airplane, and a guidance device is required for long-distance aerial photography.

[0003] However, the existing guidance devices are all small. When airplanes or other aircraft are conducting aerial photography, they are often unable to find the guidance devices, which leads to disorientation and inability to continue aerial photogrammetry. In addition, traditional guidance devices can only be used during the day, which makes it impossible to conduct aerial photogrammetry at night, greatly reducing the efficiency of aerial surveying. In addition, the existing guidance devices can only point to a single position and cannot change the guidance direction as needed. Therefore, we need to propose a marking guidance device for aerial surveying. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides: a marking and guiding device for aerial survey, such as Figure 1-4 As shown, it includes a protective box 1, a connecting column 3 and an installation frame 12, and rotating disks 4 are rotatably arranged on both sides of the installation frame 12. Several groups of exhaust vents 5 and reflectors 9 are arranged on the sides of the two groups of rotating disks 4, and laser lights 6 are clamped on the sides of the two groups of rotating disks 4. A guiding mark 8 is fixedly arranged on the top of the installation frame 12, and a driving component 13 for driving the rotating disk 4 and the guiding mark 8 to rotate respectively is arranged inside the protective box 1 and the installation frame 12. During the day, several groups of reflectors 9 reflect sunlight at multiple angles so that the aircraft in the aerial survey can quickly find the guiding device. The laser lights 6 are arranged so that the overall guiding device can still be easily found by the aerial survey aircraft at night, avoiding the need to waste a lot of time looking for the guiding device, thereby improving the work efficiency during the aerial survey, and several groups of exhaust vents 5 are arranged to prevent the rotating disk from being blown off by excessive wind.

[0023] The driving assembly 13 includes a motor 2, a driving gear 11, a rotating column 19, a transmission gear 20, a rotating shaft 21 and a telescopic sleeve rod 22. The motor 2 is fixedly installed at the bottom of the protective box 1. The bottom end of the rotating shaft 21 is keyed to the output end of the motor 2. The top end of the rotating shaft 21 rotates through the mounting frame 12 and is fixedly connected to the telescopic sleeve rod 22. The driving gear 11 is fixedly installed at the top of the telescopic sleeve rod 22. The motor 2 is started to drive the rotating shaft 21 to rotate, and the rotating shaft 21 drives the driving gear 11 to rotate through the telescopic sleeve rod 22.

[0024] The transmission gear 20 is meshed with the driving gear 11. The transmission gear 20 is fixedly sleeved on the outer arc surface of the rotating column 19, and both ends of the rotating column 19 pass through the mounting frame 12. Both ends of the rotating column 19 are vertically mounted with mounting columns 10. The two groups of rotating disks 4 are respectively fixedly mounted on one end of the two groups of mounting columns 10. When the driving gear 11 rotates, it drives the transmission gear 20 to rotate through meshing. The transmission gear 20 drives the two groups of rotating disks 4 to rotate through the rotating column 19 to ensure that the laser light 6 and the reflector 9 can transmit signals to the sky at multiple angles, so that the aerial survey flying machine can quickly find the guidance device.

[0025] Support tubes 7 are fixedly installed on both sides of the installation frame 12, and the rotating column 19 rotates and passes through the two groups of support tubes 7, and the two groups of installation columns 10 are in contact with the outer ends of the two groups of support tubes 7. The rotating column 19 rotates and passes through the support tubes 7, thereby ensuring that the rotating column 19 can rotate. At the same time, the rotating column 19 is pressed against the inside of the support tube 7 by the two groups of installation columns 10, thereby preventing the rotating column 19 from being positioned in other directions, so as to ensure that the transmission gear 20 is always engaged with the driving gear 11.

[0026] The driving assembly 13 also includes a gear column 16, a lifting motor 17 and a gear 18. The lifting motor 17 is bolted to the inner wall of the protective box 1, and the gear 18 is keyed to the output end of the lifting motor 17. The gear column 16 is fixedly sleeved on the outer arc surface of the connecting column 3, and the gear column 16 and the gear 18 are meshed. The starting cabinet lifting motor 17 drives the gear 18 to rotate, and the gear 18 drives the gear column 16 to move up and down through meshing, thereby driving the connecting column 3 to move up and down as a whole.

[0027] The outer arc surface of the top end of the telescopic sleeve 22 is rotatably sleeved with a limit sleeve 23, and the limit sleeve 23 is fixedly installed inside the installation frame 12, the outer arc surface of the connecting column 3 is rotatably sleeved with the limit column 15, and two groups of support rods 14 are bolted to the upper surface of the protective box 1, and the two groups of support rods 14 are fixedly connected to the outer arc surface of the limit column 15. When the connecting column 3 is raised or lowered, the telescopic sleeve 22 will follow the extension and retraction to ensure that it is fixedly connected to the driving gear 11, and the limit sleeve 23 is provided to prevent the telescopic sleeve 22 from being displaced in other directions. Similarly, the limit column 15 is provided to support the connecting column 3 to prevent the connecting column 3 from being displaced in other directions.

[0028] Two groups of clamping blocks 24 are fixedly installed on the outer arc surface at the bottom end of the rotating shaft 21, and a clamping groove 25 corresponding to the clamping block 24 is opened at the bottom end of the connecting column 3. When it is only necessary to drive the rotating disk 4 to rotate, the lifting motor 17 drives the connecting column 3 to move up through the gear 18 and the tooth column 16, and moves the clamping block 24 out from the inside of the clamping groove 25. At this time, the starting motor 2 will only drive the rotating disk 4 to rotate alone, and when it is necessary to drive the guiding mark 8 to rotate, the lifting motor 17 drives the connecting column 3 to descend through the gear 18 and the tooth column 16, and clamps the clamping block 24 into the inside of the clamping groove 25. At this time, the motor 2 is started, and the rotating shaft 21 will drive the connecting column 3 to rotate through the clamping block 24, thereby achieving the effect of driving the guiding mark 8 to rotate and change the reverse direction.

[0029] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
