Devices for height entertainment

Abstract

The invention provides a device for high-altitude entertainment, which belongs to the field of high-altitude entertainment. At least three gas-filled airbags are built into the cavity of the device. The device includes a barrel-shaped airbag that is filled with helium and expands with heat and contracts with cold, which is explosion-proof and flat-proof. The airbag includes a first airbag, a second airbag and a third airbag, the first airbag and the third airbag are closed airbags filled with helium gas, and the second airbag is an inflatable airbag filled with air. In the present invention, by improving the existing single airbag, the first airbag and the third airbag which are filled with light gas and closed, and the second airbag which is filled with air are set in the inner cavity of the barrel-shaped airbag, and because The second airbag is equipped with a fully automatic inflation and deflation unit to inflate or deflate according to the pressure and temperature of the air, thus ensuring that the inner pressure of the barrel-shaped airbag is stable and the shape is fixed. increased maintenance costs.

Description

Technical field [0001] The present invention relates to the field of high-altitude entertainment, in particular to a device for lift-off entertainment. Background technique [0002] At home and abroad, gas-filled balloons are usually used to carry people for lift-off entertainment. This kind of balloon is usually a single airbag filled with helium gas, and the single airbag is controlled to rise or fall through a drawstring on the ground. In the process of realizing the present invention, the inventor found that if the wind resistance is large, the single airbag is difficult to control, and the maneuverability of lift-off or landing is poor. The sharp object pierced. Since the helium gas in the single airbag is very expensive, once it falls on the ground and is punctured, the maintenance cost is high. At the same time, it is found that due to the large temperature difference in the environment, if the inflation volume is large at high temperature, it is prone to bursting dange...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a device for high-altitude entertainment, to overcome the defect of high maintenance cost caused by the single airbag in the prior art, which is easy to be punctured once it falls on the ground, and to overcome the high temperature of the airbag. Explosive, the defect of affecting the lift force at low temperature fundamentally solves the problem of letting the airbag land smoothly when the pull cord breaks accidentally
