Description

Technical Field

[0001] The utility model relates to the technical field of surveying and mapping unmanned aerial vehicles, in particular to an aerial photography and surveying and mapping unmanned aerial vehicle. Background Art

[0002] A drone is an unmanned aircraft controlled by a radio remote control device and a self-contained program control device. Drones are widely used, mainly in urban management, agriculture, geology, electricity and other fields. Drones are flexible, efficient, precise, low operating cost, wide range of applications, and short production cycle. At present, the surveying and mapping of some areas is mainly completed by drones, especially forests, lakes and other areas. Drone surveying and mapping is mainly completed by the drone's own camera, and the corresponding image is drawn using digital technology.

[0003] When existing drones are used for forest mapping, their rotating blades have no protective equipment and are easily damaged by collisions with tree branches. At the same time, when the drone is landing, the landing frame of the drone may collide with the ground and break due to improper operation. At this time, the drone is unstable when landing, which may cause the drone to tilt and its rotating blades to collide with the ground, increasing the degree of damage to the drone and the maintenance cost.

[0004] To this end, the utility model provides an aerial photography and mapping UAV, which protects the rotating blades through a protective ring and further provides a ground-mounted auxiliary bracket at the outer end of the protective ring to solve the above-mentioned problem.

[0012] Beneficial Effects

[0013] The utility model provides an aerial photography and mapping drone. Compared with the prior art, it has the following beneficial effects:

[0014] 1. The aerial photography and mapping UAV protects the rotating blades through a protective ring to prevent the rotating blades from contacting with branches when the UAV is surveying in forest areas, causing damage to the UAV.

DETAILED DESCRIPTION

[0020] 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.

[0021] Embodiment 1:

[0022] See also Figure 1-3 , an aerial photography and mapping UAV, including a frame 1, a rotating blade 2 is movably connected to the top of the frame 1, a landing frame 3 is fixedly connected to the bottom of the frame 1, the frame 1 is provided with four groups of connecting rods, the outer ends of the connecting rods are symmetrically fixedly connected to support rods 4, a protective ring 5 is fixedly connected between two groups of support rods 4, the protective ring 5 is arranged at the outer end of the rotating blade 2, the bottom ends of the two support rods 4 are fixedly connected to the support rods 6, and the bottom ends of the support rods 6 are fixedly connected to the baffle 7. The purpose of this setting is that the protective ring 5 is used to protect the rotating blades 2 to prevent the drone from colliding with tree branches when shooting and mapping in the lower layers of the forest, causing damage to the rotating blades 2 of the drone and causing the drone to fall. At the same time, the support rods 4 are used to fix the protective ring 5. The two sets of support rods 4 can be disassembled to facilitate the replacement of the protective ring 5. The baffle 7 connected to the support rod 6 enhances the stability of the drone when it lands, and prevents the drone from falling due to a malfunction. The impact force between the drone and the ground is too large, causing the landing frame 3 to break or be damaged, thereby causing the drone to tilt when it lands, thereby avoiding the collision of the rotating blades 2 with the ground, increasing the degree of damage to the drone, and further increasing the maintenance cost of the drone.

[0023] Preferably, the bottom end of the baffle 7 is symmetrically fixedly connected with a guide rod 8, the inside of the guide rod 8 is slidably connected with a slide rod 9, the bottom end of the slide rod 9 is fixedly connected with a landing plate 10, and a spring 11 is fixedly connected between the guide rod 8 and the slide rod 9. The purpose of this arrangement is that the spring 11 increases the buffering force when the landing plate 10 contacts the ground, reduces the impact force between the frame 1 and the ground, and further improves the safety of the drone when it lands.

[0024] Preferably, the baffles 7 are provided in four groups and are arranged in an annular shape with equal distances, and the baffles 7 are arc-shaped. The purpose of this arrangement is that the four groups of baffles 7 further improve the stability of the drone when it lands, can provide buffering force from four directions, and further improve the safety of the drone when it lands due to a fault.

[0025] In this embodiment, when it is necessary to conduct surveying in an area with a large vegetation coverage area such as a forest, the two groups of support rods 4 connected by the protective ring 5 are installed at the connecting rod position of the frame 1, and the support rod 6 is installed at the bottom of the two groups of support rods 4. During the surveying process, the protective ring 5 protects the rotating blades 2 to prevent the rotating blades 2 from contacting with tree branches during flight, causing the rotating blades 2 of the drone to be damaged and fall. At the same time, when the drone malfunctions and falls, the impact force between the landing frame 3 and the ground is too large, which may cause the landing frame 3 to break or be damaged. At this time, when the landing frame 3 is damaged, the landing plate 10 contacts the ground. At this time, the elastic force generated by the compression and release of the spring 11 enhances the stability of the drone when it lands. As a result, due to the damage to the landing frame 3, the drone tilts when it lands, causing the rotating blades 2 of the drone to contact the ground and cause damage, thereby reducing the maintenance cost of the drone.

[0026] Embodiment 2:

[0027] See also Figure 1-4 This embodiment provides a technical solution for an aerial photography and mapping UAV based on the first embodiment: a hemispherical shell 12 is fixedly connected to the bottom of the frame 1, and a mapping camera 13 is arranged inside the hemispherical shell 12, and the mapping camera 13 is fixedly connected to the bottom of the frame 1. The purpose of this arrangement is that the hemispherical shell 12 protects the mapping camera 13, and the mapping camera 13 is used for shooting and mapping. At the same time, the hemispherical shell 12 makes the viewing angle of the mapping camera 13 wider, so as to expand its shooting range.

[0028] Preferably, a mounting groove 14 is provided inside the hemispherical shell 12, a servo motor 15 is fixedly connected inside the mounting groove 14, and a side rod 16 is fixedly connected to the output end of the servo motor 15. The purpose of this arrangement is that the servo motor 15 is used to drive the side rod 16 to rotate, and the semicircular side rod 16 rotates about the central axis of the hemispherical shell 12, so that the bristles 17 on the inner wall of the side rod 1 have a cleaning effect on the hemispherical shell 12.

[0029] Preferably, two groups of side rods 16 are provided, and bristles 17 are fixedly connected to the inner side of the side rods 16. The purpose of this arrangement is that the two groups of side rods 16 and the bristles 17 on the inner wall clean the outer end of the hemispherical shell 12, thereby improving the clarity of the mapping camera 13.

[0030] In this embodiment, since there is more dust in the air and in rainy weather, a large amount of dust or fog will adhere to the outside of the hemispherical shell 12. At this time, the clarity of the photography by the surveying and mapping camera 13 is easily affected, thereby reducing the accuracy of the surveying and mapping. Therefore, during the shooting process, the servo motor 15 drives the side rod 16 at its output end to rotate, and the rotating side rod 16 drives the bristles 17 on its inner wall to clean the outside of the hemispherical shell 12, thereby improving the clarity of the photography by the surveying and mapping camera 13 and improving the accuracy of the surveying and mapping.
