Description

Technical Field

[0001] The utility model relates to the technical field of UAV altitude measurement components, specifically to a UAV-assisted tree height measurement component. Background Technique

[0002] When carrying out forestry operation, it is usually necessary to record the height of trees. When the saplings are short, the corresponding measuring tools can be directly used manually for measurement operations. However, when the trees grow taller, it is difficult to directly measure manually. Moreover, traditional forestry measurement methods, such as visual inspection, fixed-point monitoring, manual on-site monitoring and investigation, etc., are not only time-consuming and laborious, with high operating costs, but also not convenient enough in operation.

[0003] At present, with the rapid development of UAV technology, it has the characteristics of high flexibility, wide monitoring range, convenient operation and high automation. By installing the corresponding measuring tools on the UAV, the UAV can be used to fly to the air and then measure the tree height. Such measurement operations have the advantages of simplicity and quickness.

[0004] However, when most UAV-assisted tree height measurement tools are in use, the UAV mainly relies on the human eye to observe whether it reaches the highest point of the tree when flying to the air. This visual observation operation has a large error, and the outside of such UAVs also lacks corresponding protection components, which is easy for leaves to be inserted into the blade part of the UAV from the side, affecting the stable flight of the UAV and bringing inconvenience to users. In view of this, we have proposed a UAV-assisted tree height measurement component. Summary of the Utility Model

[0027] Please refer to Figures 1-4 , the present utility model provides a technical solution: an UAV-assisted tree height measurement component, including an UAV main body 1 and a central control box 10 provided on the UAV main body 1. An assembly plate 3 is provided at the bottom of the central control box 10. A laser rangefinder 33 is fixedly installed on the bottom surface of the assembly plate 3 for distance measurement operations; a micro motor 34 is fixedly installed on the upper surface of the bottom plate body of the assembly plate 3. The end of the output shaft of the micro motor 34 is fixedly installed with a lifting plate 35, and a laser irradiation lamp 36 is fixedly installed on the upper surface of the lifting plate 35, so as to realize that the laser irradiation lamp 36 can irradiate on the top of the tree, and then the laser rangefinder 33 is used for measurement operations;

[0028] Specifically, an outer anti-collision protective sleeve ring 2 is fixedly installed outside the UAV main body 1. Both the upper and lower ends of the outer anti-collision protective sleeve ring 2 are communicated with the outside, and the outer anti-collision protective sleeve ring 2 can perform appropriate protection operations on the blade part of the UAV main body 1.

[0029] In this embodiment, two symmetric bottom support rods 11 are fixedly installed on the bottom surface of the central control box 10. The bottom surface of the bottom support rod 11 is located below the plane where the bottom surface of the laser rangefinder 33 is located. The cross-section of the bottom support rod 11 is U-shaped, and the inside of the bottom support rod 11 is a hollow structure, so as to realize the support and protection operations on the UAV main body 1 during landing by using the bottom support rod 11.

[0030] Specifically, a plurality of inner support rods 20 arranged at equal intervals in a ring shape are fixedly installed on the inner circumferential side of the outer anti-collision protective sleeve ring 2. The inner support rods 20 are fixedly installed on the frame of the UAV body 1 to achieve normal assembly operations.

[0031] Furthermore, a plurality of mesh plates 21 arranged at equal intervals in a ring shape are provided on the outer anti-collision protective sleeve ring 2. The mesh plates 21 are plate structures with mesh holes, enabling normal ventilation operations at the positions of the mesh plates 21.

[0032] In addition, two pairs of vertically symmetric rods 30 are fixedly installed on the top surfaces of the left and right side plates of the assembly plate 3. The top ends of the vertically symmetric rods 30 are fixedly installed with fixing plates 31. The fixing plates 31 are fixedly installed on the bottom surface of the central control box 10 through a plurality of fastening screws, facilitating fixed installation operations.

[0033] It should be noted that two symmetrically arranged wiring holes 32 are provided on the bottom plate of the assembly plate 3. The inner diameter of the wiring holes 32 is between 0.8 cm and 1.3 cm, enabling wiring operations at the positions of the wiring holes 32.

[0034] It should be noted that the laser irradiation lamp 36 is located below the plane where the bottom surface of the outer anti-collision protective sleeve ring 2 is located.

The top position of the tree is irradiated by the laser irradiation lamp 36, making the UAV body 1 approximately at the same height as the tree. Then, the laser rangefinder 33 works to measure the height from the ground, and this height is the height of the tree, completing the height measurement operation.
