Description

Unmanned aerial vehicle keeps away barrier device Technical Field The utility model relates to the field of unmanned aerial vehicle design, in particular to an unmanned aerial vehicle obstacle avoidance device. Background The unmanned aerial vehicle is a fully-called unmanned aerial vehicle, is an unmanned aerial vehicle operated by utilizing wireless remote control equipment and a self-provided program control device, has no cockpit, is provided with equipment such as an autopilot, a program control device and the like, and can be divided into an unmanned fixed wing aircraft, an unmanned vertical take-off and landing aircraft, an unmanned airship, an unmanned helicopter, an unmanned multi-rotor aircraft, an unmanned parachute wing aircraft and the like, and is widely used for aerial reconnaissance, monitoring, communication, anti-diving, electronic interference and the like. The existing part unmanned aerial vehicle can utilize optical equipment to position itself, for example uses the laser range finder to confirm the distance of self and barrier to make things convenient for the staff to avoid in advance, but unmanned aerial vehicle's operation of avoiding is manual operation mostly, in case because of staff's negligence or error, makes unmanned aerial vehicle too near the barrier, can't in time avoid the operation, leads to unmanned aerial vehicle and barrier to collide, brings loss of property. For this reason, in the prior art (bulletin number: CN115617077a, bulletin day: 2023.01.17), an automatic obstacle avoidance unmanned aerial vehicle and an automatic obstacle avoidance method are disclosed, wherein a controller is configured to receive the environmental data, determine whether an obstacle exists in front of the unmanned aerial vehicle according to the environmental data, determine a distance between the unmanned aerial vehicle and the obstacle when the obstacle exists, and control the unmanned aerial vehicle to avoid the obstacle when the distance is less than a preset threshold. In the scheme, when the unmanned aerial vehicle is too close to an obstacle, the unmanned aerial vehicle is controlled to automatically avoid the operation, the unmanned aerial vehicle is prevented from colliding against the obstacle due to negligence of staff, but in the scheme, the radar, the camera body and the ranging sensor are required to be used for monitoring environmental data, the electronic devices possibly fail in long-time working, once a part is damaged, the unmanned aerial vehicle is also in risk of crashing, in addition, the propeller of the unmanned aerial vehicle does not do any protection, the propeller directly collides against the obstacle when collision occurs, the risk is high, a rod supporting a fan does not do any buffer structure, and the service life of the rod cannot be ensured. Therefore, on the basis of the existing unmanned aerial vehicle obstacle avoidance, a mechanism for carrying out quick avoidance and a mechanism for collision buffer during collision are additionally arranged, so that the technical problem that an electronic device is likely to fail during long-time working is solved, and meanwhile, a propeller needs to be effectively protected, and the service life of the unmanned aerial vehicle is guaranteed.
