Description

An emergency ventilation device for anti-piracy compartments on ships and the ship Technical Field

[0001] This application relates to the field of ship anti-piracy technology, and in particular to an emergency ventilation device for ship anti-piracy compartments and a ship. Background Technology

[0002] In recent years, piracy has become increasingly frequent and its scope has expanded. Strengthening awareness of prevention and taking effective preventative measures in ship operations has become a top priority for shipping companies and ship designers. Considering the unfavorable situation of pirates boarding the ship, measures should be taken to effectively protect the crew, including setting up anti-piracy shelters in concealed areas such as the steering gear room and equipping them with safe ventilation facilities, thus providing a guarantee for the crew's survival in the event of a pirate attack.

[0003] The ventilation system of the anti-piracy compartment must be powered on and the fan turned on to effectively maintain air circulation inside the compartment, ensuring the amount of air necessary for personnel to move around, thereby extending the rescue time.

[0004] If pirates shut down the ship's power supply, the ventilation fans in the anti-piracy compartments will not operate effectively, and air supply cannot be guaranteed. When pirates release toxic gases into the compartments through the deck ventilation openings, the crew members hiding inside will not be able to survive, and the purpose of safely waiting for rescue will not be achieved. Summary of the Invention

[0005] This invention provides an emergency ventilation device. When pirates release toxic gases through the deck ventilation openings, the crew can shut off the connection between the ventilation ducts and the deck entrances / exits inside the cabin to ensure clean indoor air. At the same time, the manual bellows effectively solves the problem of air supply inside the cabin, thereby extending the crew's waiting time for rescue.

[0006] This invention provides an emergency ventilation device for a ship's anti-piracy compartment. The device includes: an emergency air inlet duct, an emergency air outlet duct, a manual air damper, and a manual air box. One end of the emergency air inlet duct is connected to the inside of the anti-piracy compartment, and the other end is connected to an emergency air inlet outside the compartment. The manual air damper is installed on the air inlet and air outlet ducts of the conventional ventilation ducts inside the anti-piracy compartment. Opening or closing the manual air damper can correspondingly open and close the conventional ventilation ducts. One end of the emergency air outlet duct is connected to an emergency air outlet outside the compartment, and the other end is connected to the inside of the anti-piracy compartment and connected to the manual air box. When the manual air damper is closed, rotating the manual air box can drive the air inside the anti-piracy compartment to flow out through the emergency air outlet duct and allow outside air to flow in through the emergency air inlet duct.

[0007] In some embodiments, the device further includes a warning sign, corresponding to the manual damper, for reminding users to operate the manual bellows for emergency ventilation when the manual damper is closed.

[0008] In some embodiments, the manual air damper is equipped with a switch pull lock for controlling the opening and closing of the manual air damper, and the pull lock handle is respectively marked with open and closed labels.

[0009] In some embodiments, the switch zipper extends and is fixed to the bottom platform of the anti-piracy compartment for easy operation.

[0010] In some embodiments, the warning sign is configured to correspond to the manual air damper, including: the warning sign is configured to correspond to the closed latch position of the manual air damper.

[0011] In some embodiments, the number of manual air dampers is two, which are respectively installed in the air inlet duct and air outlet duct of the conventional ventilation duct in the anti-piracy compartment.

[0012] In some embodiments, one end of the emergency air intake duct is connected to the anti-piracy compartment, including: one end of the emergency air intake duct is connected to the air intake duct of the conventional ventilation duct in the anti-piracy compartment, and the interface is located at the rear end of the manual air damper on the air intake duct.
