Description

Technical Field

[0001] The present invention relates to the technical field of aerostats, and particularly to a pressure-holding cabin of a moored balloon and a moored balloon. Background Art

[0002] An aerostat generally refers to an aircraft that is lighter than air and relies on atmospheric buoyancy to lift off. A moored balloon is an unpowered aerostat moored by a cable. Compared with other high and low altitude aircraft, a moored balloon has the characteristics of long hovering time, strong weather resistance, simple and flexible deployment, low cost and low maintenance cost. As an excellent medium and low altitude platform, a moored balloon has a very wide range of applications and can play an important role in the civilian field, especially in disaster reduction, pre-disaster warning, post-disaster rescue, atmosphere and environment detection, medium and low altitude communication relay, and ground observation and monitoring.

[0003] The pressure-holding cabin is an important part of the moored balloon for high-altitude operations. Atmospheric monitoring equipment is installed in the pressure-holding cabin, including a water vapor meter, a black carbon meter, a dust meter, etc. For example: during the operation of the water vapor meter, an outlet pipe and an inlet pipe need to be connected. Therefore, pipe holes need to be opened on the shell wall of the pressure-holding cabin to lead the outlet pipe out of the pressure-holding cabin and lead the inlet pipe into the pressure-holding cabin; at the same time, to ensure the normal operation of the atmospheric monitoring equipment, the power supply line and signal line of the atmospheric monitoring equipment need to be electrically connected to the equipment outside the pressure-holding cabin. Therefore, openings corresponding to the power supply line and signal line need to be reserved on the shell wall of the pressure-holding cabin. However, during high-altitude operations, the environmental pressure in the pressure-holding cabin is low and unstable. Under the action of the pressure difference between the inside and outside of the pressure-holding cabin, the gas in the pressure-holding cabin will leak out through the pipe holes or openings, resulting in a decrease in the pressure inside the pressure-holding cabin and affecting the detection accuracy of the atmospheric monitoring equipment inside the pressure-holding cabin, thus affecting the detection results.
