Description

TECHNICAL FIELD

[0001] The utility model belongs to offshore fire fighting field, especially relate to a lifeboat rack all -round spray fire fighting device. BACKGROUND

[0002] The offshore lifeboat is an indispensable part of the ship safety facilities, and the main purpose is to provide a relatively safe evacuation means for the crew and passengers in emergency. When the ship encounters fire, collision or other conditions that may threaten the safety of the people on board, the lifeboat can quickly transfer people from the dangerous area to a safer place. Therefore, the design of the lifeboat not only considers its own durability and stability, but also ensures the usability under extreme conditions.

[0003] Fire safety in the marine environment is particularly important. Due to the distance from the land, once a fire accident occurs, external rescue forces are often difficult to arrive in time, which requires the ship to have efficient self-rescue ability. Good fire prevention measures not only can effectively prevent the occurrence of fire, but also can quickly control the situation at the initial stage of fire, reduce losses, and protect the life safety of all people on board. In addition, in some cases, an effective fire fighting system can even save the entire ship from sinking.

[0004] Although most modern ships are currently equipped with advanced life-saving equipment and fire fighting systems, there is a lack of fire fighting measures specifically designed for the lifeboat rack area in actual application. The existing fire fighting layout usually focuses on protecting the main structure of the ship and its key functional areas, and less attention is paid to the location where the lifeboat is stored. Generally speaking, although fixed water spray fire extinguishing systems or portable fire extinguishers can play a role to some extent, they are difficult to fully cover the lifeboat and the surrounding space, especially in adverse weather conditions, wind and other factors will affect the spraying effect. When a fire occurs near the lifeboat rack, personnel entering the lifeboat cannot be in the protection range of the fire fighting equipment, and if they need to rely on manual operation of the related fire fighting equipment, it may cause casualties due to slow reaction.
