Unmanned aerial vehicle

Abstract

The invention discloses an unmanned aerial vehicle which comprises a vehicle body, a propeller driving device and a connecting hole; the propeller driving device is arranged at the top of the surfaceof the vehicle body, a fork-shaped inner cavity is formed in a rotating shaft and located at the top of the vehicle body; a ball head sliding rod is slidably connected to the interior of the rotatingshaft and located at the position of the fork-shaped inner cavity; the reset spring is fixed at the top end of the ball head sliding rod and between the two corresponding sides of the interior of therotating shaft; a catkin removing device is arranged at the bottom of the surface of the rotating shaft, and a dust removing device is fixed to the inner wall of the fork-shaped inner cavity and connected with the bottom end of the ball head sliding rod in a matched mode. The invention relates to the technical field of unmanned aerial vehicle. The unmanned aerial vehicle achieves the effect of removing dust and catkin, can collect dust and catkin, prevents a large amount of dust and catkin from being attached to a joint gap of the rotating shaft or entering the interior of the vehicle body, reduces resistance, avoids part damage, guarantees normal flight of the unmanned aerial vehicle, is safe and reliable, and improves the working efficiency and the use performance.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle. Background technique [0002] With the development of society and the continuous advancement of science and technology, the use of drones is also increasing. UAV is an unmanned aircraft controlled by radio remote control equipment or self-contained program control device. In recent years, drone technology has been greatly improved, and many intelligent and multi-functional unmanned aerial vehicles have emerged. At present, UAVs are widely used in aerial photography, agriculture, plant protection, micro-selfie, express transportation, disaster rescue, observing wild animals, monitoring infectious diseases, surveying and mapping, news reports, power inspections, disaster relief, film and television shooting, creating romance, etc. Both apply well. Compared with manned aircraft, unmanned aerial vehicles have the characteristics of smal...

Problems solved by technology

[0005] In order to solve the technical problems in the background technology, the present invention proposes an unmanned aerial vehicle, which solves the problem that when the existing unmanned aerial vehicle is in use, when the wings rotate, a top-down airflow will be generated. When taking off, a large amount of dust on the ground will be blown up, and at the same time, the dust in the air will be blown downward during the flight, and in April and May every year, it enters the season when catkins are flying all over the sky, so that a large amount of dust and catkins will be scattered. Attached to the connection gap of the rotating shaft or into the body, long-term accumulation will increase unnecessary resistance, and even cause damage to components, affecting service life and reducing performance problems
