Problems solved by technology

[0003] The blimp of the prior art usually uses a metal cap to seal the helium inflation port through threaded connection. During the inflation operation, it is necessary to manually open the metal cap, connect and evacuate the inflation tube, tighten the metal cap and other necessary operations, and the operation process is complicated. And time-consuming, especially when there is an emergency and it is necessary to replenish the gas before the flight, using the existing technology is time-consuming and may miss the flight window
Secondly, the helium gas charging port is usually set on the side of the airship or near the top of the airship. After the airship is formed, the gas charging port is higher than the ground. The inflatable tube interface on the ground is used for inflating operations. In order not to cause the inflatable tube to float and hit the airship during the flight, the hanging inflatable tube needs to be fixed outside the airship before the airship is released. Some airships even need to cut the hanging inflatable tube. For sealing and fixing, these operations require manual work with the help of equipment, which will consume a lot of manpower, material resources and time
For small airships, the process of replenishing the main airbag and removing the inflation tube after the airship is formed is also time-consuming and laborious
In addition, the air pressure in the helium tank can reach more than ten or even tens of megapascals, and direct inflation will have a greater impact on the air bag. If there is a large gap, there will be a certain risk that the high-pressure and high-speed airflow will directly impact the airbag
[0004] Chinese patent application 201020266550.5 sounding air balloon filling nozzle has certain reference significance for the design and improvement of the airship inflation device, but the internal structure of the device is relatively complicated, the manufacturing cost is high, and the connection, inflation and evacuation process of the inflation device require Manual operation cannot meet the convenience and rapidity requirements of the airship inflation process, and it cannot be used directly as an airship inflation device.
[0005] Since it is inconvenient to operate the airship inflation process by using the traditional threaded connection method, the above-mentioned patent considers the use of a buckle mechanism to realize the quick connection and withdrawal of the inflation device
There are many mature snap-fit ​​self-locking structures currently on the market. For example, the charging device of a certain type of new energy vehicle can be self-locked to prevent falling off by inserting the charging gun into the car charging stand. When the charging gun is inserted into the charging stand, a certain If the self-locking structure is directly applied to the airship, it will compress the skin and capsule of the airship during the insertion process, which may cause the skin and capsule to tear, and the unlocking of the self-locking structure also requires manual operation , can not meet the application requirements of airship convenient and fast inflation
[0006] Generally speaking, there is still a certain gap between the performance of the inflatable device of the existing technology and the performance requirements of the reliability, security and safety of the airship flight test.

Abstract

The invention belongs to the technical field of aircrafts and particularly relates to a convenience quick inflator for airship balloons, comprising a fixing seat, a moving seat, an inflating mechanism, a buckle mechanism, an electromagnetic four-way valve and an electromagnetic relief valve. The convenience quick inflator for airship balloons can provide quick alignment and fastening, inflating, and release and separation; manpower, material and time materials of the inflating process are saved. The convenience quick inflator for airship balloons is reasonable in design, compact in structure,high in practicality and reliability, and convenient to maintain.

Description

technical field [0001] The invention belongs to the technical field of aircraft design, and in particular relates to a convenient and fast inflation device for an airbag of an airship. Background technique [0002] Soft airship is also called pressure airship, its shape is maintained by the buoyant gas filled in the airbag, it has the advantages of large load capacity, long empty time, low noise, low pollution and good economy, and can be widely used It has irreplaceable military and civilian value in fields such as earth observation, regional early warning, space exploration, remote sensing, and communication relay. A blimp generally includes multiple main airbags and auxiliary airbags. The main airbags are generally filled with helium, which is less dense than air and relatively safe, to provide the lift of the airship, and the auxiliary airbags are filled with air to maintain the shape of the airship. [0003] The blimp of the prior art usually uses a metal cap to seal t...
