Marine pneumatic fire door

Abstract

The invention discloses a pneumatic fireproof door for a ship. The pneumatic fireproof door comprises a constant speed door closing system and a quick door closing system; the constant speed door closing system comprises an air cylinder connected with a door plate, and the door plate is connected with a frame through a rail; the quick door closing system comprises a catapulting column evenly provided with high-pressure air tanks; and the constant speed door closing system and the quick door closing system are controlled by a control box, and the control box is provided with an alarm device. When a fire hazard happens, the alarm device senses the high temperature, the control box is triggered to start the constant speed door closing system, the air cylinder drives the door plate to move, and the door plate is closed at a constant speed; and when a door is closed, a switch on the control box is manually triggered, the high-pressure air tanks are opened, the catapulting column catapults to push the door plate to be quickly closed, and therefore various emergencies can be met.

Description

technical field [0001] The invention relates to a marine pneumatic fire door. Background technique [0002] In the event of a fire, ordinary doors cannot stop the fire, and doors made of combustible materials can easily intensify the fire. Controlling the fire within a certain range can maximize the safety of life before the arrival of firefighters. Generally, automatic fire doors adopt electric control. In case of fire, the circuit system is easily burned, and the fire door cannot be moved in place, nor can it play the role of isolating the fire. There is currently a safety door controlled by a cylinder. Although it can avoid the situation that it cannot be used due to circuit damage, it is likely to cause sudden problems such as explosions at the scene of a fire. The pneumatic door closes slowly, and cannot continue to close when it encounters explosion deformation.

AI Technical Summary

Problems solved by technology

Generally, the automatic fire doors adopt electric control. In case of fire, the circuit system is easy to be burned, and the fire doors cannot be moved in place, nor can they function to isolate the fire.

There is an existing safety door controlled by a cylinder. Although it can avoid the unusable situation due to circuit damage, it is likely to cause sudden problems such as explosions at the fire scene. The pneumatic door closes slowly, and cannot continue to close when it encounters explosion deformation.
