[0002] Aerostats generally refer to aircraft that are lighter than air and rely on atmospheric buoyancy to rise into the air. In the fields of electronics and military and civilian use, hot air balloons are generally not included in the scope of aerostats. In addition, space airships do not necessarily rely on buoyancy. In addition to military use, large civilian aerostats can also be used for transportation, entertainment, disaster relief, film and television shooting, scientific experiments, etc.

[0015] Beneficial effects:

[0016] 1. The pressure-regulated capsule aerostat is not equipped with a protective layer. The strong sunlight will cause the coating on the surface of the aerostat to fade or peel off. If the coating falls off, the aerostat body and the load equipment will be easily corroded and damaged. In addition, sunlight may also affect electronic equipment, such as causing overheating, short circuit and other faults. The protective layer can reduce the transfer of heat and extend the service life of the aerostat body and other equipment.

[0017] 2. The pressure-regulated bladder aerostat can enhance the stability between the protective layer and the aerostat body by arranging the rubber column, thereby avoiding the collision between the protective layer and the aerostat body.

[0018] 3. The pressure-regulating bladder aerostat can filter the air entering the valve body by setting a filter layer, a filter frame and a slide rail. The air after filtration enters the valve body, reducing the internal blockage of the valve body caused by large particles in the air, thereby extending the service life of the valve body. After long-term use, the filter layer is convenient for replacing the filter layer and facilitating the installation and disassembly of subsequent filter layers. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Specifically, one end of the mounting plate 16 away from the first pressure regulating valve 5 is fixedly connected to the inner right side wall of the maintenance compartment 2 .

[0027] In this embodiment, the stability of the first regulating valve during installation is enhanced.

[0028] Specifically, one end of the air outlet pipe 15 away from the first regulating valve passes through the mounting plate 16 and the interior of the maintenance chamber 2 and extends to the outside of the maintenance chamber 2 into a cavity formed between the protective layer 1 and the aerostat body 3 .

[0029] Specifically, multiple slide rails 8 are symmetrically installed inside the maintenance compartment 2, and the left and right sides of multiple filter frames 13 are movably connected to the adjacent sides of multiple symmetrical slide rails 8, and a sealing ring is provided at the connection between the filter frame 13 and the slide rail 8.

[0031] Specifically, each of the plurality of filter frames 13 is provided with a handle 9 .

[0032] Specifically, a sealing ring is provided at the connection between the filter frame 13 and the filter layer 14 .
