The technical field is as follows:

the invention relates to equipment capable of stably and safely landing a load from high altitude.

Background art:

airborne landing is widely applied to war counter-terrorism, rescue and relief work, exploration and entertainment. The parachute used when people are airborne at present mainly reduces the descending speed by the damping of a huge parachute surface to air, the descending speed and the descending direction are difficult to control, and loaded people or objects directly fall to the ground when falling to the ground, so that the people or the objects are easily injured or damaged.

The invention content is as follows:

the invention provides a device which can make people or objects stably land from high altitude and safely land; the invention is realized in such a way that the top of the parachute is provided with a large opening, a hydraulic buffer protection device is sleeved in the large opening, and the protection device consists of a hydraulic device, a pressure injection pipe, a folding bracket, a telescopic foot rest and a foot rest side belt; a propeller is arranged on a pressure pull rod of the hydraulic press. When the air-drop vehicle is in airborne state, the propeller is firstly opened, and under the action of high-speed airflow, the propeller rotates at high speed, so that the effects of stability and preliminary speed reduction are achieved, and meanwhile, the hydraulic buffer protection device is automatically opened; when the height is lowered to a proper height, the parachute is opened, and the speed is further reduced; when the landing device falls on the ground, the front end of the telescopic foot stool of the protection device firstly touches the ground, and loaded people or objects slowly touch the ground, so that the purposes of stable landing and safe landing are achieved.

Description of the drawings:

FIG. 1 is a schematic structural diagram of the present invention.

[4] The parachute is characterized in that an opening [3] is arranged at the top of a parachute [4], a hydraulic buffer protection device [2] is sleeved in the opening [3], and the [2] consists of a hydraulic device [9], an injection pipe [8], a folding support [10], a telescopic foot stool [5] and a foot stool helper belt [12 ]; [7] a pressure pull rod of a hydraulic press (9), wherein a propeller (1) is arranged on the pressure pull rod (7); [6] for loading, the load [6] is hung on the folding support [10] by a bearing lifting rope [11 ].

The propeller [1] can be folded downwards, and the folding bracket [10] can be folded upwards, so that the whole equipment can be folded when not in use; the injection pipe (8) can be made of materials with good quality, softness and toughness, and the propeller (1) and the hydraulic buffer protection device (2) can be made of materials with light quality and strong toughness.

The specific implementation mode is as follows:

when the equipment is used for airborne landing, the propeller [1] is firstly opened, and the propeller [1] rotates at a high speed under the action of high-speed airflow, so that the stable and preliminary speed reduction effect is achieved; meanwhile, a pulling force is generated between the rotating propeller, the lower part of the equipment and the load, and the pulling force drives hydraulic oil in a hydraulic press (9) to press a telescopic foot rest (5) through a pressure injection pipe (8) so as to extend the telescopic foot rest and protect the load (6); when the parachute falls to a proper height, the parachute [4] is opened, the huge umbrella cover can further damp and reduce the speed, and a large amount of air can be gathered to be sprayed out from the top opening [3] at a high speed, so that the rotation of the propeller [1] is accelerated, and the landing is more stable and slower; because the load [6] is hung on the folding bracket [10] of the hydraulic buffer protection device [2], the weight of the parachute [4] is smaller, so the parachute is easier to open and the landing position is easier to adjust by operating the parachute opening pull rope; when the telescopic foot rest falls on the ground, the front end of the telescopic foot rest [5] firstly contacts the ground; after the parachute is dropped to the ground, the parachute is folded downwards, the propeller stops rotating, and under the action of gravity, the hydraulic oil in the telescopic foot rest is pressed back to the hydraulic device, the foot rest is slowly retracted, and the load slowly lands.
