Abstract

The invention discloses an aerial photography unmanned aerial vehicle preventing from falling and being damaged based on pneumatic deceleration, and relates to the technical field of unmanned aerial vehicles. The aerial photography unmanned aerial vehicle preventing from falling and being damaged based on pneumatic deceleration comprises a vehicle frame and four fan blades, and the four fan bladesare movably mounted on the four sides of the top of the vehicle frame correspondingly; deceleration mechanisms are fixedly mounted on the four sides of the top of the vehicle frame correspondingly, and the four fan blades are located in the four deceleration mechanisms correspondingly; an anti-falling mechanism is fixedly mounted in the middle of the top of the vehicle frame, and a three-way pipeis inserted in the vehicle frame in a penetrating mode; and the top end of the three-way pipe penetrates through the top of the vehicle frame and is inserted in the front face of the anti-falling mechanism, and a solenoid valve is fixedly mounted on the top section of the three-way pipe. According to the aerial photography unmanned aerial vehicle preventing from falling and being damaged based onpneumatic deceleration, the solenoid valve is opened to drain hydrogen in a hydrogen tank into an annular air bag, after the annular air bag is expanded to the limit, on the basis of the characteristic that the density of the hydrogen is smaller than that of air, the effect that the vehicle frame bears air buoyancy is greatly improved, and thus the overall falling speed of the unmanned aerial vehicle is decreased.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an aerial photography unmanned aerial vehicle that prevents falling damage based on aerodynamic deceleration. Background technique [0002] UAVs were first used in the military. With the advancement of science and technology, civilian UAVs have been gradually promoted in recent years and are widely used in various industries. At the same time, based on different usage requirements, there are many types of UAVs. The human-machine has the largest range of use, and it is also used as the most basic drone for practice. However, in actual use, due to uncontrollable factors such as weather and improper operation by users, drones often fall. More expensive drones are destroyed. [0003] For example, the Chinese invention publication number is (CN 108216644 A), a rotor drone and its anti-fall protection device, including a frame, a protective plate, a fuselage and a br...
