Sealed fire insulation escape cabin door for ship

Abstract

The invention discloses a sealed fire-insulation escape cabin door for a ship, and belongs to the technical field of cabin doors. According to the scheme, a magnetic impact block and piezoelectric ceramics are arranged on the two sides of a separation ring respectively, only a hot melting rope is completely heated and fractured, and the separation ring is matched with attraction of the magnetic impact block and the piezoelectric ceramics; when a person pushes the escape swing door, the escape swing door and the sodium azide impact together to generate current to stimulate the sodium azide to explode to generate a large amount of nitrogen, the piston ascends to discharge all the internal solution into the mixed gas overflow cavity to react to generate carbon dioxide gas, and at the moment, the sliding gas guide pipe is pushed out by high pressure in the mixed gas overflow cavity; the sliding gas guide pipe sprays liquid and carbon dioxide gas to the two sides of the cabin door in a mist mode, a continuously-supplemented aerosol area is formed outside the cabin door, oxygen inrush is effectively reduced, internal flame detonation is prevented, and the danger that high-temperature smoke carries sparks to rush out of the cabin door to cause firing of other cabins is effectively reduced. And meanwhile, trapped people can rapidly evacuate through the escape revolving door.

Description

technical field [0001] The invention relates to the technical field of hatches, and more particularly, to a sealed fire-proof escape hatch for ships. Background technique [0002] The hatch, the door for personnel, goods and equipment to enter and exit on the aircraft, or the door opened on the bulkhead between the passages and the side shell on the ship to ensure the passage of personnel, vehicles and materials, the ship is easy to navigate at sea In case of various emergencies, such as tsunami, strong wind, and collision of the hull, the electronic components inside the hull will be damaged and short-circuited, which may easily lead to the occurrence of fire. [0003] Due to the small space inside the cabin, the oxygen content is low, and the fire spread is slow. At this time, if the cabin door is opened directly, a large amount of outside air will flow in, which will cause the fire inside the cabin to explode in an instant, resulting in the trapped personnel unable to esc...

AI Technical Summary

Problems solved by technology

[0002] Hatch door, the door for people, goods and equipment to enter and exit on the plane, or the door opened on the bulkhead and shipboard shell plate between the channels on the ship to ensure the passage of people, vehicles and materials. It is easy for ships to sail at sea. Encountering various emergencies, tsunamis, strong winds, hull collisions, etc. will cause damage to the electronic components inside the hull and short circuit, which may easily lead to fires. Without effective escape devices, life is often prone to danger

[0003] Due to the small space inside the cabin, the oxygen content is low, and the fire spreads slowly. At this time, if the cabin door is directly opened, a large amount of outside air will flow in, which will cause the fire inside the cabin to deflagrate instantly, making it impossible for the trapped people to escape in time. , at the same time the fire quickly spread to the outside, causing a wider fire, resulting in irreparable loss of life and property
