Description

Stadium top covering type captive balloon

Technical Field

The invention relates to the technical field of aerostats, in particular to a stadium top-covering type captive balloon.

Background

Large stadiums are designed with consideration to construction costs, turf maintenance, stadium ventilation, etc. and are typically constructed as uncapped structures. When a sports event is held, the sports event is usually affected by weather, such as harsh sunlight, high temperature, rainy and snowy weather, and the like, so that the event is influenced to a certain extent, and the competition experience of athletes and audiences is influenced.

The aerostat generates buoyancy by gas lighter than air in the air bag and overcomes self gravity to realize aerostatics, thereby executing a predetermined task. The captive balloon is one of aerostats, and various devices can be carried by suspending a captive cable at a predetermined position in the air, so as to complete a predetermined task.

The membrane structure is used as a covering structure or a building main body, and is a structure type which generates certain prestress in the interior in a certain mode, forms certain space shape under stress control and has enough rigidity to resist the action of external load. The Japanese Tokyo giant egg is a space shape of a membrane structure supported by the fact that the air pressure in a gymnasium is 300Pa higher than the external air pressure, and the water cube is used for filling air into an air pillow to keep the strength of the whole membrane structure.

At present, the conventional captive balloons are generally used for carrying corresponding equipment on the captive balloons, and lifting the balloons to corresponding heights to complete the predetermined tasks, and the captive balloons are only used as a vehicle for lifting and carrying, and are not used as a practical application of a top shielding tool. The large-span membrane structure needs greater strength and stability, needs a large amount of steel as a support, is heavy, and is difficult to maintain structural strength and stability, so that the practical application is less.

In view of the above situation, the creators of the invention combine actual needs to relate to corresponding product technologies to invent a stadium roof covering type captive balloon, and solve the problem of stadium roof covering by combining aerostat technology and membrane structure concept. Make whole balloon superficial through injecting into helium to balloon inside, rely on the inside atmospheric pressure of self to keep the intensity of whole balloon structure, lift the balloon to the air before the event begins, cover the top on stadium, retrieve the balloon after the event ends, satisfy the stadium event and hide the requirement of a real-time nature.
