Unmanned aerial vehicle for underground cruise

Abstract

The invention discloses an unmanned aerial vehicle for underground cruise. The unmanned aerial vehicle comprises a main body, a plurality of frame arms fixedly arranged on the main body and power mechanisms fixedly arranged at the ends of the frame arms, a driving motor is installed at the top of the main body, a first lead screw is rotationally arranged on the driving motor, a first sliding block is arranged on the first lead screw in a threaded transmission mode, a plurality of ejector rods are hinged to the first sliding block, a second lead screw is fixedly arranged at the end of the first lead screw, and a second sliding block is arranged on the second lead screw in a threaded transmission mode. According to the device, through protection of a first safety net and a second safety net, broken stones falling from a mine are prevented from hitting the unmanned aerial vehicle, and the unmanned aerial vehicle is prevented from being damaged; meanwhile, an antenna is unfolded along with a track frame, the signal transmission capacity is improved, and the signal transmission stability is guaranteed; and umbrella ribs and the ejector rods are folded, and the first safety net and the second safety net are stored, so that the unmanned aerial vehicle is convenient to store, and the storage space is saved.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to an unmanned aerial vehicle for underground cruising. Background technique [0002] The mine environment is a typical underground environment, with no GPS signal coverage, single color, few feature points, and a relatively complex environment. In order to ensure the production safety of the mine, workers inevitably go to the dangerous area of ​​the underground working face to perform inspections every day. Inspection tasks, timely detection of accident hazards and dangerous situations, the work process is repetitive and dangerous, so drones will be used instead of workers to conduct underground inspections. [0003] When the UAV is flying and inspecting the mine, it is inevitable that gravel will fall in the mine, which poses a certain degree of threat to the inspection work of the UAV. Therefore, it is necessary to install protective devices on the UA...

Problems solved by technology

[0003] When the UAV is flying and inspecting the mine, it is inevitable that gravel will fall in the mine, which poses a certain degree of threat to the inspection work of the UAV. Therefore, it is necessary to install protective devices on the UAV to adapt to the environment in the mine. To prevent the UAV from being damaged by the impact of falling objects, the existing UAV protection device is not perfect and not easy to store. At the same time, when the UAV enters a deep mine, the signal transmission is poor. The patrol inspection of the drone is affected, or even unable to work normally, which is not conducive to the inspection work
