Balloon retractable device for balloon aircraft

Abstract

The invention relates to a balloon retracting and releasing device used for a balloon air vehicle and belongs to the technical fields of balloon air vehicles. The provided balloon retracting and releasing device used for the balloon air vehicle is simple in structure, reasonable in design, capable of automatically retracting and releasing a balloon bag and small in occupied space. According to theadopted technical scheme, the balloon retracting and releasing device comprises a vehicle body framework and the balloon bag which are installed on the air vehicle, a lifting table is installed in the center of the vehicle body framework through a lifting oil cylinder, stay bar connecting seats are installed at the four corners of the lifting table, a stay bar oil cylinder connecting seat is installed among the stay bar connecting seats, each stay bar connecting seat is connected with a telescopic stay bar, the stay bar oil cylinder connecting seat is connected with stay bar lifting oil cylinders, a telescopic rod at each level of each telescopic stay bar is provided with a fixing board, the balloon bag is fixed to the fixing boards, supporting bottom boards are installed at the four corners of the vehicle body framework and provided with locking mechanisms, and the locking mechanisms are installed on the supporting bottom boards through hydraulic supporting oil cylinders. The balloonretracting and releasing device is widely used for retraction and release of a balloon.

Description

technical field [0001] The invention relates to a balloon retracting device for a balloon aircraft, which belongs to the technical field of balloon aircraft. Background technique [0002] Balloons are widely used, such as atmospheric research, skydiving training, reconnaissance and interception of enemy aircraft, and dissemination of propaganda materials. Small ones can also be used as toys. The air bag of the balloon is filled with a buoyant gas with a density less than that of air. Currently, balloon-type aircraft are widely used. Such as the application of superpressure balloons for near-space probes, airship airbags, and hot air balloons. The research on balloons at home and abroad is relatively extensive, focusing on balloon materials, pressure and working environment. The structure of traditional balloons is relatively simple, and it works in a general natural environment. The retraction and deployment mainly rely on manual work, and the balloons are not easy to fix...

AI Technical Summary

Problems solved by technology

The structure of traditional balloons is relatively simple, and they work in general natural environments. The retraction and release mainly rely on manual work, and the balloons are not easy to fix and have poor wind resistance, which limits the further development of balloon-type aircraft.
