The present invention relates to a compressed air tank for preventing sinking, and in normal times, when the pressure in the compressed air tank is lower than a certain pressure by a pressure gauge, a switch is operated, and the compressed air tank and air are compressed by an air compressor and stored at a certain pressure. If the ship is sinking due to collision with a reef, etc. and the ship starts to fill with water, the water sensor by the float switch, or the water sensor without a float switch detects water filling, the switch is turned on and the compression The servo motor of the valve, which is opened by the servo motor of the air tank, etc., rotates, and the valve of the compression tank is opened, and the air inside the compression tank is sprayed. provided to prevent sinking. There is an outer shell formed of carbon nanotubes or the like on the outside of the air bag, and it is configured to prevent the air bag from being damaged by internal objects or objects. On the other hand, when the water sensor detects that the water is full, the switch of the air compressor is turned OFF to prevent the air compressor from operating in response to the pressure change in the compressed air tank. |
