UAV (Unmanned Aerial Vehicle) anti-collision device

Abstract

The invention discloses a UAV (Unmanned Aerial Vehicle) anti-collision device. The UAV anti-collision device comprises fan protection frames, a base, a hell and springs, wherein grooves are formed inthe upper ends of corners of the shell; the fan protection frames are arranged on the upper ends of the grooves; fans are arranged at the inner parts of the fan protection frames; each fan comprises amotor, and the output end of the motor is rotationally connected with a rotating seat through a rotating shaft; a controller is arranged at the inner part of the shell; the lower end of the controller is connected with an ultrasonic transducer through a guide wire in series; the base is fixedly arranged on the lower end of the shell; the left end and the right end of the base are connected with upper supports in a welding way; the lower ends of the upper supports are fixedly connected with the springs; the springs are connected with fixed blocks in a winding way. According to the UAV anti-collision device disclosed by the invention, by arranging the fan protection frames, the fans, the ultrasonic transducer, the upper supports and the springs, the problems that fans of a UAV are exposed and are easy to collide with an object, the UAV can be damaged as the UAV often directly collides with the ground due to too fast landing speed during landing, and the economic loss is caused are solved.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicle collision avoidance, in particular to an unmanned aerial vehicle anti-collision device. 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 it is equipped with autopilot, program control device and other equipment. The personnel on the ship or the remote control station of the parent aircraft use radar and other equipment to track, locate, remote control, telemetry and digital transmission. 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 control with a ...
