Abstract

The invention provides a photoelectric control valve of an aerostat. The photoelectric control valve of the aerostat comprises a valve cover, a seal ring, multiple columns, a base, a control circuit, a valve body, an opening-closing mechanism portion and a limiting mechanism portion, wherein the valve body is arranged on a bag body of the aerostat. The multiple columns are respectively located between the base and the valve body to enable the base and the valve body to be connected. The valve body is provided with a valve port and used for air in an air bag in the aerostat to be discharged out. An outer circle of the valve port is sleeved in an inner hole of the seal ring, and the valve cover covers the seal ring and the valve port and is in a sealed state. A flange structure of the lower end face of a lead screw of the opening-closing mechanism portion is fixed to the valve cover, and the lead screw is used for opening and closing the valve cover and enabling the valve cover to be away from and cover the valve port. A motor of the opening-closing mechanism portion is connected with the control circuit and controls lifting and downward moving of the valve cover in the vertical direction. The lead screw is provided with a threaded hole, a stopping block of the limiting mechanism portion is fixed to the lead screw through the threaded hole, and the stopping block vertically moves with the lead screw to block infrared light emitted by an upper limiting optical coupling assembly and a lower limiting optical coupling assembly of the limiting mechanism portion and cut off the control circuit and accordingly enables the motor to stopping running.

Description

technical field [0001] The invention relates to the technical field of aerostats, and relates to a photoelectrically controlled exhaust valve for aerostats, which can adjust the pressure difference between the inside and outside of the aerostat to make it safe and reliable and maintain its aerodynamic shape. Background technique [0002] An aerostat generally refers to a soft-structure aircraft whose specific gravity is lighter than air and relies on atmospheric buoyancy to lift into the air. The aerostat is composed of an airbag made of polymer composite material and various equipment and payloads arranged on the airbag. The airbag is filled with a buoyant gas with a density lower than that of air, and the density difference between the inside and outside of the airbag provides the aerostat buoyancy, thereby completing the lift-off of the aerostat. [0003] Aerostats generally include balloons and airships. The formed aerostats are launched from the ground. As the flight a...
