AI Technical Summary

Technical Problem

Existing aircraft separation anti-collision propeller shaft structures have insufficient impact resistance, limited protection range, are inconvenient to disassemble and assemble, and are time-consuming and costly to maintain.

Method used

A separate anti-collision propeller shaft structure for aircraft, including a crash shield and a connecting rod, was designed. The crash shield is automatically attached to the connecting rod by magnetic plates. During disassembly and assembly, pressing the connecting rod separates the crash shield from the connecting rod. The use of carbon fiber crash shield and magnetic metal connecting rod increases the protection range and ease of disassembly and assembly.

Benefits of technology

It improves the lifespan of the propeller and the stability of the aircraft, reduces maintenance time and costs, enhances shock resistance and protection range, and enables a convenient disassembly and assembly process.

Abstract

The utility model relates to the technical field of aircrafts, in particular to an aircraft separation anti-collision propeller shaft which comprises an aircraft fuselage. The aircraft further comprises an anti-collision cover and a connecting column, a controller and a storage battery are fixedly connected to the interior of the aircraft body, and a camera is fixedly connected to the front end of the aircraft body; by using the anti-collision cover and the connecting columns, the controller controls the propellers to rotate to drive the aircraft to fly, the anti-collision cover reduces the probability that the propellers directly collide with obstacles, the service life of the propellers is prolonged, the protection range is large, and after flight is finished, the anti-collision cover is pressed to damage the two connecting columns in the group to enable the connecting columns to move towards the connecting rods; the anti-collision cover and the connecting rod are separated, a new anti-collision cover is replaced, the magnetic attraction piece is close to the connecting rod to be automatically attracted and aligned, fixation is assisted, stability is improved, manual adjustment time is shortened, the connecting column is loosened to move towards the anti-collision cover, installation and fixation of the anti-collision cover and the connecting rod are achieved, overall disassembly and assembly are convenient, maintenance cost is reduced, and compatibility is high.
