Detailed Description
As shown in figures 1 and 2, the whole appearance of the hot air helium mixed balloon is in a water drop shape, and the fabric of the balloon body is high-strength polyethylene flame-retardant fabric, and comprises a hot air balloon 1, a helium balloon 2, an auxiliary balloon 3, a hanging basket and accessories 4, a heater 5, an operating system 6, an external isolation heat-preservation layer 7, a helium valve 8, a fuel system 9, an inflation and deflation valve 10 and a bearing rope 11.
The hot air bag 1 mainly stores heated air, the density of the air in the hot air bag is reduced after the air is heated by the burner, the weight of the air is lighter than that of cold air with the same volume outside the air bag, and partial lift force is provided for the air bag. The air pocket is installed at the air inlet at the lower part of the hot air bag, so that air flow can be guided into the balloon, and the situation that the balloon is difficult to fill under the condition of air pressure is avoided.
The helium gas bag 2 mainly stores helium gas, and a certain lifting force is stably provided by using the helium gas. And the stable buoyancy provided by the air bag can enable the air-stagnation height and the air-stagnation time of the balloon to be far longer than those of a conventional hot-air balloon.
The auxiliary air bag 3 is mainly characterized in that after the balloon is lifted to a certain height, air is thin, the pressure intensity of helium in the helium bag 2 is greater than that of the outside of the sphere, and partial helium needs to be released into the auxiliary air bag 3 through the helium valve 8, so that the sphere air bag is prevented from being damaged due to overlarge pressure difference between the inside and the outside.
The hanging basket 4-1 is made of non-metal materials such as rattans or glass fiber reinforced plastics and is rectangular, the upper part of the hanging basket is provided with a hole, the bottom of the hanging basket is provided with a landing buffer device, and the hanging basket is provided with a hanging connecting buckle and is connected with the balloon through a connecting cable 4-2.
The heater 5 is mainly used to heat air and comprises two burners, forming a dual redundancy design to prevent failure.
The operating system 6 consists of an air exhaust valve 6-1 and an operating rope 6-2. Pulling down the control rope 6-2, opening the air exhaust valve 6-1, exhausting hot air from the hot air balloon, loosening the control rope 6-2, finishing the exhaust, and utilizing the exhaust gas and the burner to enable the balloon to ascend and descend.
The external insulating layer 7 is mainly used for reducing the loss of air heat, so that the dead time and the rising speed of the ball body are kept by using less fuel consumption rate.
The helium valve 8 is a one-way valve, when the pressure in the gasbag 2 is larger than a set value, the helium valve 8 is opened, partial helium is released into the auxiliary gasbag 3, the internal and external pressure difference of the gasbag is kept, and the safety of the sphere is ensured.
The fuel system 9 is composed of a first fuel tank 9-1, a second fuel tank 9-2 and an air supply pipeline 9-3.
The first inflation and deflation valve 10-1 is arranged on the side wall of the helium bag, the second inflation and deflation valve 10-2 is arranged on the top of the auxiliary air bag, and the first pet deflation valve and the second inflation and deflation valve are used for filling and recovering helium in the helium bag in a ground state.
The bearing ropes 11 and a plurality of bearing lead wire ropes 11 are connected with the auxiliary air bags, the helium air bags and the hot air bags and are used for bearing partial load and reducing the stress of the bag body.
When the balloon needs to be lifted, the balloon is firstly paved on the ground, an inflation hose is connected with a first inflation and deflation valve 10-1 to inflate helium into a balloon helium air bag 2, the balloon is in a spherical shape, then a heater 4 is ignited, the hot air bag 1 is gradually filled with hot air, the balloon starts to lift, the combustion flame of the heater is adjusted to adjust the lifting speed and the height of the balloon, when the sphere rises to a certain height, the pressure difference between the helium bag 2 and the outside is too large, and helium in the bag air bag releases part of the helium to enter a secondary air bag 3 through the helium valve 8 so as to prevent the sphere from cracking. When the balloon needs to descend, the control rope 6-2 is pulled, the air exhaust valve 6-1 is opened, and the ball descends. After the balloon is used, helium is collected into the helium storage container by the first inflation and deflation valve 10-1 and the second inflation and deflation valve 10-2, and the balloon is folded and packaged.
