AI Technical Summary

Technical Problem

The existing drone evacuation capsule loses attitude control after falling into the water and cannot automatically return to its correct position, resulting in poor stability. This may worsen the injuries of the wounded, cause medical equipment to malfunction, and pose a risk of suffocation.

Method used

The design combines a ring-shaped buoyancy structure with an eccentric center of gravity adjustment mechanism. The ring-shaped buoyancy structure provides redundant buoyancy, while the eccentric center of gravity adjustment mechanism dynamically adjusts the center of gravity to achieve automatic righting of the hull. Combined with a water-sensitive vent valve and a side-flipping wing panel assembly, it ensures that the hull quickly returns to a stable attitude after falling into the water.

Benefits of technology

It enables reliable self-floating and automatic righting of the drone transport capsule in harsh sea conditions, ensuring the safety of the casualty's survival space and the normal operation of medical equipment, and improving the survival probability and attitude recovery robustness under extreme conditions.

Abstract

The invention relates to the field of rescue, in particular to an unmanned aerial vehicle rear delivery cabin with self-floating and side-turning returning functions. Comprising a cabin body, an annular buoyancy structure and an eccentric gravity center adjusting mechanism. The cabin main body forms a sealed wounded accommodating space; the annular buoyancy structure is fixedly arranged on the periphery of the cabin main body, the annular buoyancy structure comprises a plurality of independently sealed buoyancy components, and the plurality of buoyancy components are circumferentially distributed around the outer surface of the cabin main body; the eccentric gravity center adjusting mechanism is arranged on the lower portion in the cabin body and comprises a balancing weight and a balancing weight moving guide rail, the balancing weight is installed on the balancing weight moving guide rail in a sliding mode, and the balancing weight moving guide rail extends in the longitudinal direction of the cabin body. According to the unmanned aerial vehicle rear delivery cabin, crossing from passive floating to active stability maintaining is achieved on the unmanned aerial vehicle rear delivery cabin, and the core safety problems that in the background technology, after falling into water, the posture is out of control, and automatic returning cannot be achieved are effectively solved.
