Description

Umbrella-free air-drop device

Technical Field

The utility model relates to an air-drop device and peripheral supporting facility technical field especially relate to an umbrella-free air-drop device.

Background

When rescue and relief work, search and rescue of lost trapped personnel and emergency supply in a battlefield, materials need to be delivered from the air because the materials cannot be accessed from the ground. In such cases, it is often necessary to urgently deliver small items such as food, drinking water, medicines, or communication equipment. Conventional aerial delivery systems typically use a parachute as the deceleration device; the honeycomb paper, the foam plastics, the air bag and the like are used as buffer devices during landing, so that the landing impact force is reduced, and the damage of materials is prevented. Parachute air-drop systems are relatively complex in structure, require long-time preparation, and are costly. When a large amount of small and low-value materials need to be airdropped, a large amount of materials are often bundled together for dropping in order to improve the efficiency-cost ratio. The disadvantages of this approach are: 1. when facing complicated weather and terrain conditions, ground personnel often can not obtain materials because the landing site has deviation. For example, when people trapped in flood enclosed areas or mountainous areas are rescued, the area available for landing is often small, the thrown materials can be washed away when falling into the surrounding water, and the thrown materials are difficult to pick up when falling into canyons, so that the rescue purpose cannot be achieved. 2. Because the trapped hedgehog is gathered in a narrow area, the situation that the personnel are hit by an airdrop to cause casualties often happens in practice. 3. The goods and materials are easy to fall under the control of a few people, and a large number of people, particularly vulnerable groups such as old people, children and women cannot obtain rescue goods and materials. To avoid this, it is necessary to use an umbrella-free aerial delivery system that is less costly and simpler to use, and to dispense small pieces from a relatively low height.

Patent publication No. CN208036877U discloses a low-level, umbrella-free airdrop package comprising a carton and a carton for accommodating the carton, and a liner for supporting the carton. The carton includes support frame and parcel at the outside sleeve of support frame. The paper box, the paper box and the liner are all made of corrugated paper. The corrugated board is deformed to achieve the effect of protecting products, and the packaging container is simple in structure, small in size and easy to transport and stack; the packaging mode is simple, the opening is convenient, and the requirement of low-altitude air drop in disaster relief is particularly met. Patent publication No. CN103448911A discloses an umbrella-free air-drop bag for solid food materials and a manufacturing method thereof, comprising a main bag and an auxiliary bag filled in the main bag. The main bag comprises a protective bag, a reinforcing bag and a sealing bag, wherein the two side edges of the protective bag, the reinforcing bag and the sealing bag are sewn together from inside to outside. The protection bag adopts the polyethylene material to make, strengthens the bag and adopts the flexible container cloth material to make, and the encapsulation bag adopts the oxford cloth material to make, assists the bag for adopting the individual layer bag body of flexible container cloth, and the encapsulation bag reaches and assists the bag and be provided with the magic subsides that seal the usefulness in open position. The impact during landing can be effectively slowed down by adopting a multilayer buffer structure, and the umbrella-free air-drop of solid food is completed. The patent with publication number CN106742708A discloses a food parachute-free air-drop bag for emergency and disaster relief, which comprises an outer bag, a first inner bag and a second inner bag, wherein the first inner bag is arranged in the outer bag, the second inner bag is arranged in the first inner bag, the second inner bag comprises a first bag area and a second bag area, inflatable cushions are arranged in the first bag area and the second bag area, a safety rope is arranged at one corner of the outer bag, and a handle belt is arranged on the outer bag. Through the umbrella-free air-drop bag provided by the utility model, the impact of landing can be effectively slowed down by adopting a high-strength bulletproof fiber structure for the outer bag, and the umbrella-free air-drop of food is completed; the inner bag adopts a multi-layer high-elasticity and high-elasticity rubber-plastic integrated composite material structure, so that food can be effectively prevented from leaking and polluting.

In summary, when a large amount of small and low-value materials are air-dropped, an umbrella-free air-dropping system is often used for air-dropping from low altitude or ultra-low altitude, and the common umbrella-free air-dropping systems are classified into two types, one type is a system without an aerial speed reducer and the other type is a system with an aerial speed reducer.

Systems without aerial deceleration absorb the energy of the landing impact primarily by means of structural parts of the aerial delivery container and attached cushioning material. The system has low cost and is convenient to package, transport and put, but has the problems of high descending speed of materials, large landing impact and easy damage of the materials, so the system is mainly used for air-dropping the materials with light dead weight and difficult damage, such as food, solid medicines and the like. Such systems are not suitable for aerial delivery of equipment and fragile goods, nor for delivering supplies to dense populations.

The system with the aerial speed reducer is provided with a small-sized fan cover, a speed reducer and the like on an aerial delivery container, can reduce the speed in the descending process, and is combined with an attached buffer device to reduce the landing impact. The system has slow falling speed, is beneficial to reducing the damage to materials and the injury to ground personnel, but has the problems of small capacity of a single container, complex structure and troublesome packaging, transportation and throwing when a large amount of throwing is needed.

Generally speaking, the existing parachute-free air-drop technology is difficult to simultaneously consider simple and easy use and good deceleration buffer effect, and particularly the using effect is not ideal when a large number of small goods and materials are air-dropped. Therefore, it is an urgent need to solve the problem of the art to provide an umbrella-free air-drop device that is simple and easy to use and has a good deceleration and buffering effect.
