Problems solved by technology

The air intake device and the exhaust device of the existing aerostat are two separate devices, and a single device cannot satisfy the intake and exhaust at the same time; in addition, the air intake device of the aerostat generally relies on the wind force of the fan to open the one-way However, with the continuous expansion of the application range of aerostats and the development of stratospheric aerostats in various countries, the pressure head of the fan is low at high altitude (the pressure head of the fan is proportional to the air density), and the fan will not be able to blow open smoothly. One-way valve, the air intake efficiency of the fan is affected

Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0024] figure 1 Shown is the structure diagram of the intake and exhaust device in a static state, figure 2 shown as figure 1 The A-A sectional view of the air intake and exhaust device is used to exhaust or supplement the air inside the aerostat, which includes a one-way valve, fan 7, motor 1, rolling shaft 2 and two pull ropes 3. The one-way valve is mainly composed of a housing 11 , a base 12 , a hinge 5 , a rotating assembly (including a torsion spring 4 , a rotating shaft 15 , and connectors) and a mounting flange 13 .

[0025] The housing 11 is open at both ends and hollow inside. One en...

Abstract

The invention relates to an air intake and exhaust device and an aerostat with the same. The air intake and exhaust device is used for exhausting or supplementing air in the aerostat and comprises a one-way valve, a blower, a motor, a rolling shaft and two pull ropes, wherein the one-way valve comprises a housing, a base and a mounting flange; the blower is mounted on the mounting flange; the blower and the base are positioned on two opposite sides of the mounting flange; the blower can output wind power to open two hinges on the base; the motor is accommodated in the housing and fixed on the inside wall of the housing; the rolling shaft is driven by the motor to roll and is parallel to the plane where the mounting flange is arranged; and the motor drives the rolling shaft to rotate to drive the two pull ropes to be wound on or unwound from the rolling shaft, so as to open or close the two hinges. The invention has the advantage that air exhaust of the one-way valve and air intake of the blower can be realized in the same passage.

Description

technical field [0001] The invention relates to an aerostat, in particular to a device for supplementing or releasing air in the aerostat to adjust the pressure difference between the inside and outside of the aerostat. Background technique [0002] The aerostat is a kind of soft structure aircraft. The aerodynamic shape is maintained by adjusting the pressure difference inside and outside the aerostat. The pressure difference between the inside and outside of the aerostat is generally kept within a certain range. This range is related to the weight distribution, air density, air velocity etc. When the aerostat is rising or falling, the external atmospheric pressure is constantly changing. The aerostat needs to discharge or replenish the internal gas, and adjust the internal and external pressure difference to achieve the required value to maintain the aerodynamic shape. The air intake device and the exhaust device of the existing aerostat are two separate devices, and a si...
