Description

Technical Field

[0001] The utility model relates to the technical field of low-altitude surveying and mapping, in particular to a low-altitude surveying and mapping device which is convenient to adjust. Background Technique

[0002] Traditional aerial photogrammetry refers to a method of continuously taking pictures of the ground in the air by using aerial surveying and mapping equipment. After obtaining image data, combined with ground measurement control points, etc., control points are encrypted indoors to obtain the exterior orientation elements of the images.

[0003] Currently, general aerial surveying devices use unmanned aerial vehicles (UAVs) to carry camera equipment. However, when the current UAVs land, the landing gear directly makes hard contact with the ground, so it is easy to have a relatively violent collision during landing, which may cause the UAV to tilt and turn over. At the same time, when different surveying and mapping devices are carried on the UAV, the overall weight will also change. If a single fixed buffer is used, it cannot adapt to the landing processes of different weights.

[0004] Therefore, a low-altitude surveying and mapping device which is convenient to adjust is proposed. Summary of the Invention

[0005] The purpose of the utility model is to provide a low-altitude surveying and mapping device which is convenient to adjust, so as to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A low-altitude surveying and mapping device which is convenient to adjust, including a UAV main body, a surveying and mapping camera is installed at the center of the bottom of the UAV main body, and landing gears are symmetrically installed on both sides of the bottom of the UAV main body;

[0007] A support rod is slidably connected to the bottom of the landing gear, a plurality of connecting rods are slidably connected to the support rod evenly, a bottom plate is installed at the bottom ends of the plurality of connecting rods, and springs are sleeved on the outer sides of the plurality of connecting rods.

[0008] Preferably: A chute is opened at the bottom end of the landing gear, sliders are installed at both ends of the support rod, and the sliders are slidably connected to the inside of the chute.

[0009] Preferably: A threaded rod is installed on the slider, and the threaded rod penetrates through the inside of the chute.

[0010] Preferably: A gasket and a nut are respectively installed on the threaded rod.

[0011] Preferably: A limiting plate is installed at the top end of the connecting rod.

[0012] Preferably: A rubber pad is installed on the lower surface of the bottom plate.

[0013] Preferably, a reinforcing rod is installed between the landing gears.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows: when the device lands on the ground, the connecting rod and the spring can play a certain buffering role, avoiding hard contact. At the same time, by adjusting the position of the support rod, the process of landing with different weights can be adapted, improving the stability of the device landing.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0020] Please refer to Figures 1-3 , the present utility model provides a technical solution: a low-altitude mapping device that is convenient to adjust, including a UAV main body 1, a mapping camera 2 is installed at the center of the bottom of the UAV main body 1, and landing gears 3 are symmetrically installed on both sides of the bottom of the UAV main body 1;

[0021] A support rod 6 is slidably connected to the bottom of the landing gear 3, and a plurality of connecting rods 9 are slidably connected to the support rod 6 evenly. The bottom ends of the plurality of connecting rods 9 are installed with a bottom plate 7, and springs 8 are sleeved on the outer sides of the plurality of connecting rods 9.

[0022] As Figure 2 and Figure 3 shown: a chute 5 is opened at the bottom end of the landing gear 3, and sliders 12 are installed at both ends of the support rod 6. The sliders 12 are slidably connected to the inside of the chute 5; through the above settings, the mutual cooperation between the sliders 12 and the chute 5 can make the support rod 6 more convenient and faster to adjust up and down.

[0023] As Figure 3As shown: A threaded rod 13 is installed on the slider 12. The threaded rod 13 penetrates through the inside of the chute 5. A gasket 14 and a nut 15 are respectively installed on the threaded rod 13. Through the above settings, the threaded rod 13 cooperates with the gasket 14 and the nut 15, so that the position of the support rod 6 can be restricted and fixed.

[0024] As Figure 2 and Figure 3 shown: A limit plate 11 is installed at the top of the connecting rod 9. Through the above settings, the position of the connecting rod 9 is restricted, avoiding the situation where the connecting rod 9 separates from the support rod 6.

[0025] As Figure 3 shown: A rubber pad 10 is installed on the lower surface of the bottom plate 7. Through the above settings, hard collisions can be avoided when contacting the ground, enabling the device to land more stably and preventing the device from bouncing due to the reaction force of hard collisions.

[0026] As Figure 3 shown: A strengthening rod 4 is installed between the landing gears 3. Through the above settings, the strength between the landing gears 3 is provided, ensuring the stable operation of the device.

[0027] Working principle: Install the surveying and mapping camera 2 on the UAV main body 1, and then adjust the position of the support rod 6 according to the overall weight of the device. First, loosen the nut 15 to enable the support rod 6 to move up and down. When the overall device is heavy, move the support rod 6 downward to increase the distance between the bottom plate 7 and the landing gear 3, so that the spring 8 can be compressed more. Thus, when the device lands, it can be avoided that the bottom plate 7 contacts the bottom end of the landing gear 3 prematurely, and then the situation of collision and vibration occurs. When the overall device is light, move the support rod 6 upward to effectively avoid the situation where the spring 8 rebounds greatly and bounces the device up when landing. When the position of the support rod 6 is appropriate, fix its position through the nut 15 to complete the overall adjustment work.

[0028] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
