The invention provides a drag parachute-based lifeboat air automatic inflation device, which comprises a guide parachute (9), a drag parachute (10), a lifeboat (11), a gas cylinder pull rope (12), a main cable (13) and a cylinder valve assembly (14), the guide parachute (9) is connected with the lifeboat (11) through a rope, and the cylinder valve assembly (14) communicated with an inflation bin is arranged on the inflation part of the lifeboat body of the lifeboat (11). The cylinder valve assembly (14) is connected with the drag parachute (10) through the gas cylinder pulling rope (12), the drag parachute (10) is arranged between the guide parachute (9) and the lifeboat (11), one end of the drag parachute (10) is connected to the lifeboat (11) through a rope, the other end of the drag parachute (10) is connected with the guide parachute (9) through rope connection, the initial inflation time of the lifeboat (11) is prolonged, and automatic inflation of the lifeboat (11) in the air isachieved. The device is simple in structure, convenient to operate and high in reliability.
本发明提供一种基于阻力伞的救生船空中自动充气装置,包括引导伞(9)、阻力伞(10)、救生船(11)、气瓶拉发绳(12)、主缆绳(13)和瓶阀组件(14),引导伞(9)通过绳索与救生船(11)连接,救生船(11)船体充气部上设置有与充气仓相连通的瓶阀组件(14),瓶阀组件(14)通过所述气瓶拉发绳(12)与所述阻力伞(10)连接,在引导伞(9)和救生船(11)之间设置有所述阻力伞(10),阻力伞(10)一端通过绳索连接在救生船(11)上,另一端通过绳索连接与引导伞(9)连接,使救生船(11)起始充气时间延长,实现救生船(11)在空中自动充气。本发明结构简单,操作便捷,可靠性高。
