Embodiment Construction

[0038] The present invention will be further described below in conjunction with specific examples, but the protection scope of the present invention is not limited thereto.

[0039] Implementation example 1, a hydrogen energy airship with a new airbag layout, such as figure 1 As shown, airbag and power unit 6 are included. The airbag comprises a main airbag 3 and a plurality of secondary airbags 1. The inside of the main airbag 3 is provided with several partitions in parallel along its length direction, and the partition divides the inner cavity of the main airbag 3 into a plurality of compartments with the same volume. The secondary airbags 1 are located around the main airbag 3, and the number of the secondary airbags 1 is the same as the number of the compartments.

[0040] Helium gas is stored in the main airbag 3 , and flammable gas (hydrogen gas) is stored in the auxiliary airbag 1 .

[0041] The controller is respectively connected with the motor 6, the pressure sen...

Abstract

The invention provides a hydrogen energy airship with a novel air bag layout. The airship comprises air bags and a power device; the air bags include a main air bag and a plurality of auxiliary air bags; a plurality of partition plates are arranged in the main air bag, and an inner cavity of the main air bag is divided into a plurality of compartments by the partition plates; the auxiliary air bags are located on the periphery of the main air bag, the auxiliary air bags are connected with the compartments in the corresponding main air bag through channels provided with adjusting valves; and each auxiliary air bag is connected with a hydrogen loop through a branch pipeline. The multiple auxiliary air bags are adopted for storing hydrogen, the property that the hydrogen serves as floating gas is utilized, and the load of the airship is improved; secondly, the scale of hydrogen leakage is reduced, and the risk of hydrogen leakage is reduced from the source; and on the premise of ensuring that the hydrogen is fully diluted to be below the explosion limit by the helium when the hydrogen leaks, the amount of the helium for dilution is saved.

Description

technical field [0001] The invention relates to the field of aerostat design, in particular to a hydrogen energy airship with a novel airbag layout and a method for using it. Background technique [0002] Airship is a kind of aerostat that uses air buoyancy to achieve airborne performance. Compared with other aerostats that require power maintenance, it has the characteristics of low power consumption and heavy load. It has been widely used in entertainment, surveying and mapping, weather observation and other fields. [0003] Some new research shows that some low-density, flammable gases that can be used as airship fuel can be directly stored in the airship airbags to provide part of the buoyancy and simultaneously serve as airship fuel. [0004] However, unlike helium, when the flammable gas at the explosive limit concentration comes into contact with air, a violent reaction will occur, which seriously threatens the safety of airship operation. Therefore, for the airbag s...
