The invention belongs to the technical field of ship design and construction, and discloses a positive pressure protection device, a ship and a positive pressure protection method.The positive pressure protection device comprises a shell, a main draught fan, a standby draught fan, a first air brake, a second air brake, a pressure difference detector and a control system, the shell can communicate with a cabin, and the air supply end of the main draught fan and the air supply end of the standby draught fan both communicate with the shell; the first air brake is arranged between the air supply end of the main fan and the shell and used for controlling communication or closing between the main fan and the shell. The second air brake is arranged between the air supply end of the standby fan and the shell and used for controlling communication or closing between the standby fan and the shell. The pressure difference detector is used for detecting the air pressure difference inside and outside the cabin; and the control system is in communication connection with the main fan, the standby fan, the first air brake, the second air brake and the pressure difference detector. When the main fan breaks down, the control system can enable the positive pressure protection device to be immediately and automatically switched to the standby fan to supply air so as to maintain the positive pressure in the cabin.
本发明属于船舶设计及建造技术领域,公开了一种正压保护装置、船舶及正压保护方法,包括壳体、主风机、备用风机、第一风闸、第二风闸、压差检测器和控制系统,壳体能够与舱室连通,且主风机的送风端和备用风机的送风端均与壳体连通;第一风闸设置于主风机的送风端与壳体之间,用于控制主风机与壳体之间的连通或封闭;第二风闸设置于备用风机的送风端与壳体之间,用于控制备用风机与壳体之间的连通或封闭;压差检测器用于检测舱室内部和舱室外部的气压差;控制系统与主风机、备用风机、第一风闸、第二风闸和压差检测器均通信连接。当主风机故障时,控制系统能够使正压保护装置立即自动切换到备用风机进行送风,以维持舱室内的正压。
