Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a UAV rotating shaft protection device that avoids the shaking of the fan blades and automatically lubricates it. By increasing the contact area between the stabilizing mechanism and the rotating shaft, the stability of the rotating shaft is improved, and the rotation of the rotating shaft is avoided. The vibration is transmitted to the fan blade, which improves the stability of the fan blade, and can reduce the friction of other components of the rotating shaft, maintain the advantages of the service life of the rotating shaft, solve the vibration of the rotating shaft that will cause the vibration of the fan blade, and increase the life of the fan blade The amplitude of the vibration will cause the flight of the aircraft to be unstable, and it will not be possible to lubricate the rotating shaft during the rotation process, resulting in the heat generated by the rotating shaft during the rotation, which will cause the loss of lubricating fluid and increase the friction between the rotating shaft and the surrounding components. , reducing the service life of aircraft equipment

Abstract

The invention relates to the technical field of intelligent unmanned aerial vehicles and discloses an unmanned aerial vehicle rotating shaft protection device capable of preventing fan blades from shaking and achieving automatic lubrication. The unmanned aerial vehicle rotating shaft protection device comprises a lubricating mechanism, wherein the lubricating mechanism comprises a sliding block, a magnetic block is fixedly connected to the interior of the sliding block, and an electromagnetic rod is placed on the side face of the sliding block; a reset spring is fixedly connected to the side wall of the side, close to the electromagnetic rod, of the sliding block, an infusion tube is fixedly connected to the side wall of the sliding block, and a guide block is fixedly connected to an end, away from the infusion tube, of the sliding block. The magnetic block is pushed to move through the electromagnetic rod, the magnetic block is fixedly connected into a sliding block, a surface of the sliding block is rotationally connected with a movable connecting rod, and the other end of the movable connecting rod is rotationally connected with a movable block, so the contact area of the movable block and the rotating shaft is increased, and stability of the rotating shaft is improved by increasing the contact area of a stabilizing mechanism and the rotating shaft; vibration generated by rotation of the rotating shaft is prevented from being transmitted to the fan blades, and stability of the fan blades is improved.

Description

technical field [0001] The invention relates to the technical field of intelligent unmanned aerial vehicles, in particular to a protection device for the rotating shaft of an unmanned aerial vehicle that avoids fan blade shaking and automatically lubricates. Background technique [0002] Unmanned aerial vehicles can replace human beings in the fields of agricultural production and geological exploration, which improves the efficiency and scope of work. The current aircraft fan blades will be affected by wind and vibration after lift-off, and the vibration of the shaft will Causes the vibration of the fan blades, increases the vibration amplitude of the fan blades, causes the flight of the aircraft to be unstable, and cannot lubricate the rotating shaft during the rotation process, causing the heat generated by the rotating shaft during the rotation to cause the loss of lubricating fluid , which increases the friction between the rotating shaft and the surrounding components,...
