Antenna for communication of plant protection unmanned aerial vehicle

Abstract

The invention belongs to the technical field of unmanned aerial vehicles, and particularly relates to a communication antenna for a plant protection unmanned aerial vehicle, which comprises an unmanned aerial vehicle body, a second-stage antenna, a first-stage antenna, a lifting mechanism, a positioning assembly, a first-stage antenna, a second-stage antenna, a second-stage antenna, a first-stage antenna, a second-stage antenna, a second-stage antenna and a second-stage antenna, the positioning assembly is arranged on one side of the lifting mechanism, the rotating mechanism is arranged in the protection shell, the secondary antenna is perpendicular to the unmanned aerial vehicle body when working, and when the secondary antenna needs to be stored, the rotating mechanism operates, the positioning assembly is far away from the lifting mechanism, and the positioning assembly rotates along with rotation of the rotating mechanism; the positioning assembly gradually slides out of the bottom of the lifting mechanism, and the secondary antenna and the lifting mechanism gradually rotate along with the rotating mechanism. According to the invention, the antenna can be stored during the flight of the unmanned aerial vehicle, so that the antenna can be prevented from being damaged due to collision with branches or other foreign matters.

Description

technical field [0001] The invention belongs to the technical field of drones, and in particular relates to an antenna for plant protection drone communication. Background technique [0002] In recent years, with the rapid development of UAV technology, people can use UAVs to complete some difficult, dangerous, toxic and harmful tasks. UAVs can be used for plant protection, surveying and mapping, photography, high-voltage cables and agricultural and forestry inspections, etc. Work, in the field of plant protection, drones can be equipped with buckets to spray pesticides on plants. Most drones are remotely controlled wirelessly on the ground, so most drones are equipped with antennas for sending and receiving signals. [0003] Most of the antennas used by existing plant protection drones are fixed on the drone body, and the ends of the antenna are mostly higher than the drone itself. In places with many trees, the antenna is very easy to collide with the branches. As a resul...

Problems solved by technology

[0003] Most of the antennas used by existing plant protection drones are fixed on the drone body, and the ends of the antenna are mostly higher than the drone itself. In places with many trees, the antenna is very easy to collide with the branches. As a result, the antenna will break after being hit, and the antenna will no longer be able to send and receive signals, which may cause the drone to lose control and fall from the sky
