Expandable inflatable membrane structure air-drop device and operation method thereof

Abstract

The invention relates to the field of air-drop packaging boxes, in particular to an expandable inflatable membrane structure air-drop device and an operation method thereof. The device comprises an outer airbag type expandable inflatable membrane structure box body, an inner airbag type expandable inflatable membrane structure box body, an outer cable rod framework, an inner cable rod framework and an elastic limiting mechanism. The outer cable rod framework is installed on the edge portion of the outer airbag type expandable inflatable membrane structure box body and connected with the outer airbag type expandable inflatable membrane structure box body. According to the expandable inflatable membrane structure air-drop device, multiple energy dissipation mechanisms of landing impact of an air-drop bag are achieved, and the air delivery time and space of materials are saved through quick inflation and assembly; and the problems that the parachute air-drop hit rate is poor and the landing time is long are solved, the device is suitable for delivering solid and liquid substances in different shapes, work is efficient, the structure is reasonable, cost is low, and industrialization is easy.

Description

technical field [0001] The invention relates to the field of airdrop packaging boxes, in particular to an airdrop device with an expandable inflatable membrane structure and an operating method thereof. Background technique [0002] In construction, disaster relief and modern warfare, it is often necessary to use air delivery to deliver various materials. For example, in earthquake-stricken areas, due to serious damage to houses and roads, vehicles cannot pass normally. In order to ensure people's basic living needs, airdrops are often used to deliver rescue Materials are delivered to designated areas in a timely manner. However, conventional box-type airdrop devices mostly use wooden or plastic packing box structures, which take up a lot of space and increase the load of the aircraft, which affects the load capacity of the airdrop. The poor impact resistance during the airdrop process is not conducive to normal transportation and airdrop operations; and , the large volume ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, there are many studies on the slow release and shock absorption of the airdrop box. For example, the patent application number CN201821562641.6 discloses a bottom plate of the airdrop box, and the patent application number CN201810078698.7 discloses a foam Aluminum airdrop box buffer module, foam aluminum airdrop box, application numbers CN201520718781.8 and CN201510590950.9 patents disclose an airdrop box with an airbag protection device. This type of patent is limited to the research on the cushioning module, and there are many shock-absorbing objects It is a rigid box; in addition, there is also a patent with the application number CN201910283305.0 disclosing an airdrop device with positioning tracking and identification functions and its use method, which is mainly for accurately positioning the box after airdrop; in addition , there are also patents with application number CN201920568639.8 disclosing an inflatable airdrop box, and patents with application number CN201110379163.1 disclosing a soft-folding airdrop box. , but its shock absorption and energy consumption measures are less, and it is difficult to apply in practice
