Mountain and ravine multifunctional flying crane cross-country ambulance vehicle and its control method

Abstract

The invention relates to a method for performing fly-lifting rescue in mountain ravine and an off-road ambulance. A large-diameter main duct coaxial positive and negative rotation dual rotor wing or a fan bears the main lifting force; a plurality of small-diameter duct rotor wings and fans are horizontally and symmetrically arranged at the periphery of the large-diameter main duct coaxial positive and negative rotation dual rotor wing or the fan; a connecting arm can do telescopic torsional swing to do four-degree-of-freedom action and bear the auxiliary lifting force, direction control and vortex ring prevention; a variable inertia system is arranged in a fly lifter system and has the capacity of resisting turbulence transition wind; a plasma energy wave generator with a vortex ring prevention function is provided; and a fly lifter preferably consisting of the five-axis five-duct six-rotor wing or a fan is provided with an energy transmission pulling cable and is combined with an ambulance with high land off-road capability to form a multi-functional fly-lifting rescue ambulance scheme. The off-road ambulance has the take-off capability under the atrocious weather, has the arm far longer than that of the conventional lifting vertical crane, can perform long-distance lifting rescue task and solves the world problem that the conventional ambulance is difficult to go up and down the escarpment to rescue people and things to be rescued when the accident occurs in the mountain ravine.

Description

technical field [0001] The invention relates to a multifunctional flying crane rescue method and the field of off-road ambulance vehicles for emergency rescue in the event of car accidents in mountains, ravines and mountain roads falling off cliffs. Background technique [0002] Occurred all over the world in mountain forests, ravines and rugged mountainous areas, people who climbed cliffs or injured people in mountain road crashes were in urgent need of rescue. Sufficient distance is extended to the rescue site, and the accompanying rescuers and medical personnel cannot go down the ravine cliff, or cannot lift the wounded after going down, which is time-consuming and laborious, and the manpower is insufficient, so they are not qualified for perfect rescue operations. Ambulances and cranes in the prior art do not have professional supporting rescue tools (such as rigid ladders) for climbing and descending beyond a distance of 130 meters. General ambulances have limited volum...

Problems solved by technology

Its ability to resist turbulent, sudden, shear, transitional winds and crosswinds is not as good as that of single-rotor helicopters

[0007] Two: From the analysis of the requirements of the use environment: if a helicopter is used for rescue, it can only be convenient for rescue operations in the daytime, when there are no high-voltage lines in the surrounding airspace and an unobstructed wide environment. Due to the influence of the airflow around the mountains and ravines, the influence of the environmental climate day and night conditions, some disaster sites are very close to the cliffs and slopes, and the rescue work is also very dangerous, which also limits the use of helicopters for safe rescue.

There is no use of the principle of helicopters to improve the technology to set up the equipment with flying crane function to solve the difficult problem of rescue of the injured and injured in the mountains and ravines, and it is also difficult to solve the problem of completing rescue tasks under harsh weather and environmental conditions.
