Gas-liquid-solid coupled airborne loading combined buffer device

Abstract

The invention discloses a gas-liquid-solid coupled airborne loading combined buffer device. In device, an airborne material storage box, buffer airbags, an inner spherical shell, a buffer liquid and an outer spherical shell are arranged in a manner of wrapping airborne materials layer by layer from inside to outside; various pairs of corresponding connecting rings are hooked through a plurality ofbuffer springs to achieve connection between the airborne material storage box and the inner spherical shell; the buffer airbags are arranged in the gap between the airborne material storage box andthe inner spherical shell; the buffer liquid is injected into a buffer liquid containing cavity between the inner spherical shell and the outer spherical shell; and the inner spherical shell and the outer spherical shell are each composed of two hemispherical half shells, and clamping grooves and clamping keys on every two hemispherical half shells form clamping structures for assembling. Throughthe layer-by-layer wrapping method, the airborne materials can be buffered at multiple levels, and besides, the spherical design can realize all-round buffer protection of the materials, so that the attitude requirement of an airborne device during landing is reduced, and the capability of adapting to bad weather and complex landing terrains for airborne landing is enhanced.

Description

Technical field [0001] The invention relates to the field of safety protection for airborne loads, in particular to a gas-liquid-solid coupling airborne load combined buffer device. Background technique [0002] The airborne load is the materials needed for airborne to the destination, which is of great practical significance in military and earthquake relief. Since airborne materials will bear huge impact loads on the ground at the moment of landing, in order to ensure the safe landing of airborne materials for the subsequent use of airborne materials by ground receivers, protective buffer devices must be used to reduce the damage to materials caused by impact loads. [0003] In the actual airborne landing process, the existing airborne device has the following problems: [0004] 1. Existing load-carrying airborne devices mostly use large-area parachutes to slow down the materials to safely land on the ground. However, this type of airborne device always has the problem of direct ...

AI Technical Summary

Problems solved by technology

However, this type of airborne device always has the problem that the airdropped equipment directly touches the ground or rebounds or even overturns, which will cause great damage to the materials, especially the airborne that cannot adapt to bad weather and complex landing terrain.

[0005] 2. In order to overcome the problem that the airdrop device directly touches the ground, a small part of the prior art designs an anti-turnover device on the airborne device and arranges a buffer protective airbag at the bottom of the device, but the buffer protective airbag arranged at the bottom of the device is easily caught by the ground when it touches the ground. Piercing by sharp objects causes the airbag to deflate or the internal pressure of the airbag is too high to cause the airbag to burst, which will cause fatal damage to the airdropped materials

[0006] 3. Most of the existing load airborne buffer devices use airbag buffer devices, and most of them are single-chamber airbag buffer devices with a single structure. There are no other forms of buffer devices, resulting in limited effective buffer strokes and buffer forms. Therefore, Can't play a good buffer effect on airborne materials
