The invention relates to an outboard
inflatable plugging air bag, which consists of a master rod kit, a high-pressure air controller, an air bag seat, an air bag, a positioning pin, a supporting device and a high-pressure air container, wherein the master rod kit consists of a master rod and an end cover; the master rod is a
pipe fitting with a sealed end, and the center of the sealing end is provided with a screw hole; the high-pressure air controller consists of a body, a top rod
system, a
check valve, a
blowoff valve and a stuffy cover; the air bag seat consists of a master piece of the
airbag seat and an accessory of the air bag seat, and the air bag seat is sleeved on the master rod and can make axial movement on the master rod; the air bag is divided into an inner layer and an outerlayer; when not being inflated, the air bag is in a cylindrical shape, and a sealing air bag space is formed between the two
layers; the positioning pin consists of a positioning pin tongue, a positioning pin seat, a positioning pin spring, a positioning pin pull ring and a positioning pin substrate; and the supporting device consists of a
handle, a supporting rod, a cross rod and a chuck. The outboard
inflatable plugging air bag is suitable for the plugging after various ships are damaged, and thus, the outboard
