Description

Technical Field

[0001] The utility model relates to the technical field of survey unmanned aerial vehicles, in particular to a field survey unmanned aerial vehicle. Background Art

[0002] For example, in the field of architectural design, in order to timely understand the scale information of the construction site, manual surveying and mapping operations are generally used traditionally. However, manual surveying and mapping operations are not only inefficient, but also for some complex or dangerous environments, manual surveys have great difficulties and safety risks. With the rapid development of science and technology, drone technology has been widely used in many fields, especially in the field of field surveys.

[0003] At present, drones have gradually replaced traditional surveying methods with their advantages such as high efficiency, flexibility and safety. The field survey drones on the market mainly use flight control systems and sensor equipment. Through remote control or autonomous flight, they perform image acquisition, terrain mapping and other tasks in the target area, which has the advantage of improving the survey efficiency to a certain extent.

[0004] Since a survey host and a support are generally installed at the bottom of a field survey drone, the survey host can generally be rotated for angle adjustment, but the support is fixed on the field survey drone. In this case, when the survey host is rotated to perform survey operations at multiple angles and directions during subsequent surveys, the support will block the image capture of the survey host, affecting the survey effect and causing inconvenience to the user. In view of this, we propose a field survey drone. Utility Model Content

Two symmetrical connecting rods 26 are fixedly installed on the annular side surface of the fixed sleeve 21. A support rod 261 with a U-shaped cross-section is fixedly installed at the end of the connecting rod 26, which is convenient for using the driving motor 24 to drive the survey host 2 to rotate. Since the connecting rod 26 is fixed on the fixed sleeve 21, as the fixed sleeve 21 rotates, it can drive the survey host 2 and the connecting rod 26 to rotate at the same time, so that the connecting rod 26 and the support rod 261 will not hinder the normal survey of the survey host 2.

[0028] In this embodiment, a fixing plate 241 is fixedly mounted on the end of the output shaft of the driving motor 24 , and the driving gear 25 is fixedly mounted on the bottom surface of the fixing plate 241 by a plurality of fastening screws, so as to facilitate the fixing and mounting operation of the driving gear 25 .

[0029] Specifically, horizontal rods 262 are fixedly installed at both ends of the support rod 261, and the horizontal rods 262 are used for supporting operation.

[0030] Furthermore, a buffer pad 27 is sleeved on the horizontal rod 262, and the buffer pad 27 is used for buffering and protecting operations.
