Novel unmanned aerial vehicle with fan blade protection covers

Abstract

The invention discloses a novel unmanned aerial vehicle with fan blade protection covers. The novel unmanned aerial vehicle comprises an unmanned aerial vehicle body and high-speed motors fixedly mounted on the unmanned aerial vehicle body. A fan blade is arranged at the upper end of each high-speed motor. A clamp groove is formed in the side face of each high-speed motor. Rod joints are arranged in each clamp groove. A mounting rod is arranged on each rod joint. A protection ring is arranged on the heads of the mounting rods of each high-speed motor. A protection cover is arranged on each protection ring. Each rod joint comprises a sphere and a barrel. A first mounting hole is formed in each barrel, and second mounting holes are formed in the side face of each protection ring. According to the novel unmanned aerial vehicle with the fan blade protection covers, the protection rings are additionally mounted on the outer portions of the fan blades, and the fan blades can be effectively protected against impact damage of foreign bodies; meanwhile, the protection covers are arranged at the upper ends of the protection rings in a sleeving manner, and tree leaves and other sundries can be prevented from falling into the protection rings and influencing rotation of the fan blades; and safety is high, and practicality is good.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a novel unmanned aerial vehicle with a protective cover for wind blades. Background technique [0002] Unmanned aircraft, referred to as "UAV", is an unmanned aircraft controlled by radio remote control equipment and its own program control device. There is no cockpit on board, but equipment such as autopilot and program control device are installed. The personnel on the ground, on the ship, or at the remote control station of the parent aircraft track, locate, remotely control, telemeter and digitally transmit it through radar and other equipment. Under the radio control, it can take off like an ordinary aircraft or be launched into the air with a booster rocket, and it can also be taken into the air by the parent aircraft for flight. When recovering, it can automatically land in the same way as the common aircraft landing process, and can also be recovered by remote co...

AI Technical Summary

Problems solved by technology

However, most of the propeller blades of common UAVs on the market are directly exposed, and there are no protective devices around the blades, so it is very easy for the blades to be interrupted by debris such as branches, causing unmanned The drone crashes, and the cost of a drone is often high, so the property loss after the crash is huge. In view of the above situation, a new type of drone with a wind blade protective cover can be designed to solve the above problems
