Rotor protecting device for unmanned aerial vehicle

Abstract

The invention discloses a rotor protecting device for an unmanned aerial vehicle and relates to the technical field of unmanned aerial vehicles. The rotor protecting device for the unmanned aerial vehicle comprises an unmanned aerial vehicle body and a rotor protecting device; the rotor protecting device is arranged on a rotating arm of the unmanned aerial vehicle body; the rotor protecting devicecomprises a supporting column and a protecting disc; the supporting column is hinged with the protecting disc; a plurality of supporting blocks are arranged at the bottom of the supporting column; fixing devices are arranged on the supporting block; the protecting disc is in a circular disc shape; a through hole is formed in the central position of the upper end surface of the protecting disc; aplurality of circular wheels are arranged on the side surface of the protecting disc; water drain pipes are arranged on the supporting blocks; and hoses connected with the through hole and the water drain pipes are arranged in the protecting disc, the supporting column and the supporting blocks. The rotor protecting device for the unmanned aerial vehicle can protect rotors of the unmanned aerial vehicle against being collided and washed by rainwater.

Description

Technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle rotor protection device. Background technique: [0002] Generally, if the drone suddenly encounters rain during the flight, the flight mission needs to be terminated immediately, otherwise the rain will damage the rotor, and the flight is also prone to danger in rainy weather. In order to overcome the weather conditions Inconvenience, a rain-proof device is needed. For example, the application number CN201520642344.2 discloses an unmanned aerial vehicle rotor protection device, which is installed on a rotor support to protect the rotor, and includes an annular retaining ring. One end of the upper pull rod is fixedly connected, the other end of the upper pull rod is fixedly connected with the same mounting ring, the annular retaining ring is also hinged with one end of the plurality of pull-down rods, and the other end of the pull-down rod is...

Problems solved by technology

[0002] Generally, if the UAV suddenly encounters rain when flying, it needs to terminate the flight mission immediately, otherwise the rain will hit the rotor and cause damage to the rotor, and flying in rainy weather is also prone to danger. In order to be able to overcome the weather conditions Inconvenience, need a kind of rainproof equipment, such as the application number is CN201520642344.2 discloses a UAV rotor protection device, used to be installed on the rotor support to protect the rotor, including an annular retaining ring, the annular retaining ring and multiple One end of each upper tie rod is fixedly connected, the other end of the upper tie rod is fixedly connected with the same installation ring, the annular stop ring is also hinged with one end of a plurality of lower rods, and the other end of the lower rod is provided with a hook, The upper pull rods are uniformly distributed along the circumferential direction of the annular retaining ring, the lower rods are uniformly distributed along the circumferential direction of the annular retaining ring, and a plurality of hook rods are installed on the rotor support matched with the lower rods, and the upper part of the rotor support includes a sliding section and a fixed section, the fixed section is arranged on the upper part of the sliding section, the fixed section is rotatably connected to the installation ring, and the diameter of the sliding section is smaller than the diameter of the inner hole of the installation ring

But this kind of UAV protection device is not suitable for use in rainy weather
