The invention relates to the technical field of aerostats, and discloses an air pressure switch, a pressure maintaining device and a high-altitude balloon restraining and releasing device. The air pressure switch comprises a strain surface and a strain detection component. The strain surface is formed on a wall surface of a sealed container and is used for generating deformation in a preset direction when air pressures inside and outside the sealed container are different; and a detection end of the strain detection component corresponds to the strain surface and is used for outputting a trigger signal when a dependent variable of the strain surface reaches a preset value. The air pressure switch disclosed in the invention is simple in structure and low in cost; weather resistance is good;in a floating environment of a high-altitude balloon, a restraining device of the high-altitude balloon is controlled to be reliably released at a preset height; meanwhile, stable air pressure in thepressure maintaining device can be controlled to be maintained so that a stable air source is provided for related load equipment, and a problem that reliable control over a working state of a cutterand the working state of an air pump in the high-altitude balloon floating environment is generally difficult to implement through an existing control means is solved.
本发明涉及浮空器技术领域,公开了一种气压开关、保压装置及高空气球约束释放装置,该气压开关包括:应变面与应变检测元件;应变面形成于密封容器的壁面,应变面用于在密封容器内外的气压出现差异时,产生预设方向的形变;应变检测元件的检测端与应变面相对应,用于在应变面的应变量达到预设值时输出触发信号;本发明所示的气压开关结构简单、成本低廉,耐候性好,可在高空气球的浮空环境下,控制高空气球的约束装置在预设高度进行可靠释放,同时,还可控制保压装置内维持稳定的气压,以便对相关载荷设备提供稳定的气源,克服了现有的控制手段普遍难以对高空气球浮空环境下的切割器及气泵的工作状态实施可靠控制的问题。
