Hull airbag

Abstract

In order to improve the anti-risk capability of a ship, the invention provides a hull airbag which is characterized in that hull airbag bodies (1) are mounted through adopting quickly inflated film blocks made of material such as rubber or plastic, and are arranged on the inner wall and the outer wall of a ship body (2), a blast pump (4) mounted on a marine engine (3) is used for inflating, compressed air is delivered into keel air cylinders (6) in a cabin through a first air delivery pipe (5) to be stored, when risks come, an automatic inflation valve (7) is automatically opened, the hull airbag bodies (1) on the inner wall and the outer wall of the ship body (2) are inflated with compressed air in the keel air cylinders (6) through a second air delivery pipe (8), the automatic inflation valve (7) and an air inlet valve (9), the hull airbag quickly swells to form a ship shaped like a float bowl, collision, stranding, overturning and sinking of the ship can be prevented, the safety of the ship and the possessions is ensured, and meanwhile, the life safety of personnel is also ensured.

Description

Technical field [0001] The invention relates to safety facilities of ships, in particular to a hull safety airbag that resists collision, grounding, overturning and sinking. Background technique [0002] From ancient times to the present, ships have been very good water vehicles for human beings. As water carriers, they have to face various safety risks on water and underwater at any time, especially small and medium-sized ships. Their own risk resistance ability is very poor. In the event of an accident, many ships will capsize and sink, causing loss of property and personnel. [0003] In order to make the ship safer and become a very safe water carrier, it is a problem that has not been solved. The present invention is based on the principle of rapid inflation and huge buoyancy of airbags and pontoons, and combines various materials such as rubber and plastics. The advantage is that a fast-inflatable hull safety bag is provided. This fast-inflatable hull airbag has not been used...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problem of poor anti-risk ability of ships, the present invention sets a rapidly inflatable airbag according to the principle that airbags and buoys have fast inflation and high buoyancy, combined with the advantages of rubber, plastic and other materials with good tensile properties and durability The diaphragm is installed on the inner and outer walls of the hull. The airbags are multiple independent individuals. If a single one is damaged, it will not affect the inflation of other airbags. The hull airbag is installed with a stretchable rubber film or a strong plastic film block with super glue or pressure strips. On the inner and outer walls of the ship, usually use a vacuum pump to pump out the air in the air bag to make it close to the hull, making it a protective film for the hull to prevent seawater erosion
